The Impact of Earnings Transparency on Cost of Capital

Abstract— The existence of earnings transparency has significant financial consequences in recent years. Earnings transparency decrease information asymmetry which is positively associated with cost of capital. Therefore, this paper investigates whether the earnings transparency can decrease the cost of capital. We use adjusted R2s from annual panel regressions based on the explanatory power of stock return in relation with earnings and change in earnings as earning transparency measure. This study applies the ordinary least squares (OLS) method to estimate cost of capital model for 80 firms listed on Tehran stock exchange market from 2009 to 2013. The result shows the earnings transparency has significant impact on the cost of capital, even when the earning transparency measure is not considerable. Moreover, the earning transparency decrease the cost of capital, which there is significant negative relation between expected cost of capital and earning transparency measure. Hence, earnings transparency protects the interests of shareholders, which provide a lower cost of capital.

The effect of exchange rate unification policy on drug prices in Iran during 2001-2003

Abstract — One of the main problems in drug sector is the mandatory dependence of this sector on the limited resources of foreign exchange. The change in economic structure of country gradually from the middle of the first development plan influenced Iran’s pharmaceutical system, so far as single exchange reported in 2001. Indeed, large efforts that were made to perform this policy led to gradual removal of subsidized exchange from domestic drugs till the end of the year 2003. Performing this policy has raised discussions among Supporters and opponents. This study aimed to investigate the effect of exchange rate unification performance on drug price. This study is an analytic-descriptive study that has been carried out using the information on 2001-2003. To calculate the changes in drug prices affected by exchange rate unification performance on drug price, Fisher price index was used. The results of this study indicate that the extent of changes in total drug prices using Fisher price index in 2001-2003 is about 13.01 and 31.99, respectively. Total increase in drug price affected by exchange rate unification performance in 2001, 2002 and 2003 has been about 3221, 2890 and 3179 billion, respectively. With retrospect to exchange rate unification resulting in high inflation rate, the government must provide exchange rate for fundamental goods including drug in order that performing this policy does not lead to changing drug price; on the other hand, provisions must be provided in order that reimbursement of incremental costs is transmitted from patient to third-party payers and insurers. To share risk and cover higher risks, it is suggested to use Franchise afloat.

Determining the life-cycle through the cash flow patterns taken from the cash flow forms

Abstract— One of the methods for distinguishing the stages of the life cycle of the firms was presented by [1]. In this method, to differentiate the stages of the firm's life-cycle, the model created by the positive and negative signal of the layers of the cash flow forms concerning the operational levels (investment, operationalization, and financial supplies) is used. Attributing each of the cash flow patterns to the stages in the life cycle in firms has been done using the economic theories. The features related to the cash flows of the life cycle can be determined through the economic theory. Knowing the stages of the life cycle in firms can help the credit-givers, investors, and the most important user of the accountant information in predicting the future situation of the firms. In other words, the conditions in which the firm is seen help the users of accountant information to have a better evaluation of the financial information of the firm, the present and future needs (like the need for investment and financial supplies) and also the capacity and action of the management. In this study, the method for determining the patterns of cash flows, its superiority over other methods of determining the life cycle and theories about the patterns of cash flow will be explained in detail.

Developing a Monitoring System for Non-point Pollutants in Groundwater Sources using BAISINS Software (Case Study of Sivand River before It Joins the Kor River in Fars Province)

Abstract—The Sivand River and the Kor River are located in the northwest of Fars Province. The Kor River originates from the southern heights of the Zagros Mountains, flows for about 310 kilometers, and pours into Bakhtegan Lake. Along its course, many floodways and rivers join it, the most important of which is the Sivand River. The Sivand River flows for 47 kilometers and joins the Kor River near Marvdasht at Pol Khan. These two rivers are almost the only main sources of water needed in agricultural activities in the northern and central plains of the Province. Previous research suggested parts of the Kor-Sivand Basin had water of desirable quality while other sections were heavily polluted with varying degrees of point and nonpoint pollutants. The software BASINs 4.0 and the HSPF model were used to study more carefully the issue of pollution sources. The use of this model made it possible to investigate nonpoint pollution sources (before the Sivand River joins the Kor River) and the N  and DO factors at 5-, 10- , and 15- year intervals.

Wastewater Treatment in Northern Isfahan Plant Using REDO Method Compared with Pilot Scale

Abstract— So far, numerous studies were conducted in the field of wastewater treatment discharged from treatment plants using modern techniques in order to achieve output standards in terms of wastewater treatment plants including the U.S Environmental Protection Agency (EPA) and World Health Organization (WHO). Therefore, this study was performed in order to determine the optimal dose, power and efficiency of REDO disinfection system to eliminate or reduce substantially total coliform level in a wastewater treatment plant in Northern Isfahan in 2011. This is an experimental-applied study. For the first time in the Middle East, the effect of four disinfectants such as chlorine (Cl2), chlorine dioxide (ClO2), oxygen (O2) and ozone (O3) produced in the electro-lysis solution of water and salt using REDO device with 200 liters per hour capacity and 118 liters per minute input wastewater flow at pilot and Batch scales was examined in order to determine the optimal dose of disinfectant solution for the purpose of eliminating total coliform level and decreasing total trihalomethanes in wastewater output in treatment plant in Northern Isfahan. In addition, coliform level of wastewater samples was measured both before and after wastewater treatment. Laboratory results showed that 4-ppm injection of this solution decreased disinfection of total coliform from 7.9 x 106 in pilot scale to 69 mpn in 100 mL while the latter decreased to 31mpn in 100 mL in the closed scale. The results also indicated that this solution causes a slight reduction in COD and a slight increase in TDS in the output wastewater. Based on these results, the best injection dose is 4 ppm with 99.9% efficiency. This dose causes substantial reduction in total coliform in wastewater discharged from treatment plants to surface waters, adsorbent wells and agricultural and environmental uses.

Genotypic Pattern Analysis of Forage Yield in Agropyron cristatum by using AMMI model

Abstract— In order to determine yield stability of Agropyron cristatum over six environments in Iran, 18 accessions were evaluated based on randomized complete block design with three replications at rainfed and irrigated conditions in Karaj, Mashhad and Boroojerd research stations, Iran. Total annual dry matter (DM) yield were collected and averaged over two years. Stability parameters were calculated as additive main effect and the multiplicative interaction analysis (AMMI). Based on AMMI analysis, the main effects of environment, accession and interaction effect of environment × accession were significant (p<0.01). In AMMI analysis, the first two principal component axes were significant (p<0.01) and justified 83.1% of total genetic by environment interaction variation. The AMMI biplot IPCA1 vs. IPCA2 scores for both genotype and environments showed G7 and G11 accessions were close to the center of the biplot and had the least interaction based on both two components and were considered as more stable accessions over all tested environments. Accessions G2, G16, G17 and G12 had the highest specific adaptation to rainfed condition. In contrast, G14 and G8 accessions had the highest specific adaptation to irrigated environment of Mashhad and similarly, G3, G7, G18, G15 and G6 accessions had higher specific adaptation to the irrigated environments in Boroojerd.

Design a public swimming pool based on ecological perspective

Abstract—In this paper, a public swimming pool is designed with an ecological perspective, due to the energy crisis in the country, air pollution caused by the use of conventional fossil fuels and also the need for civil society in Iran especially in arid tropical area. Shahrood city has an excellent situation for the use of solar energy and the construction of a public swimming pool because of the special geographical position, locating in the border areas of desert and a lot of sunny days throughout the year. It is used the structure of several pools based on solar energy in different continents for the design of this swimming pool with considering the climate and ecosystem of Shahrood city. Some features like the use of solar energy for heating pool water cycle, education to promote respect for the environment for energy conservation, and reduce pollution in the pool for a tourist attraction addition to attraction for sport and recreation, can be noted for this design. Finally, with considering to the lack of ecological pool with this approach in Shahrood city and different advantages of it, providing the funding and implementation of it could have a major impact on various aspects of Shahroodian people life.

The analysis of organizational education and training system from economic view and human capital and its role in sustainable development

Abstract-The social organizations are some of the foremost phenomena at present time. Many requirements are met by organizations in modern world. By the aid of their resources including technology, information, financial sources, and human capital the organizations meet the social requirements. The human capital of the organizations is deemed as the paramount and most effective organizational sources since other sources are perishable but the human capital can be developed. To realize this objective, the reviewing scientific method has been employed. The results of this investigation indicate that the growth and excellence of human capital in the organizations might be only possible through organizational education and training. This issue suggests that organizational investment in growth and development of human capital is more efficient than investment in physical and equipment- related dimensions and it contributes the organizations in realization of their goals and growth and development of organizations will help to national growth and sustainable development from various dimensions. Thus, organizations should change their attitude from equipment- centered view to education and learning- centered approach. Of course, fulfillment of this important point requires serious investment in the field of training and education. 

Forage yield stability in populations of Agropyron cristatum using parametric stability methods

Abstract— The Forage Dry matter (DM) yield were investigated for 18 accessions of Agropyron cristatum in an experimental based on randomized complete block design with three replication at two environmental conditions (rainfed and irrigated) in three research station as Mashhad, Brojerd and Karaj, Iran. The stability parameters of coefficient of variation (CVi), Shukla's stability variance (δ2i), Wricke's ecovalance (Wi2), Deviation from regression (S2di), Eberhart/Russell regression coefficient (bi) and coefficient of determination (Ri2) were estimated for all of accessions. According to Eberhart and Russel (1966) method the accessions G5, G10 and G11 with slope of 1.0 with low deviation from regression coupled with higher DM yield over six environments considered as more stable. Accessions G1 and G9 had (bi<1) and higher DM yield for poor environment. The Accessions G13, G15 and G18 showed (bi>1) and indicate sensitivity to environmental changes for DM yield. To better understand the relationships among the parametric stability statistics and assessment of stable accessions, principal component analysis (PCA) was used. The results of (PCA) showed that the two first components explained 48.58% and 38.31% of total variation. The accessions of G11, G18, G12, G10 and G7 were superior based on all stability parameters and the accessions of G17, G15 and G13 were stable based on CVi, Wi2 and S2di and had a high yield. The accessions of G1, G3, G5, G8 and G4 were classified as stable accessions based on δ2i, bi and Ri2 and this group had a low mean yield. The accessions of G16, G2, G9, G14 and G6 had a week stability and DM yield based on all calculated parameters and means of DM yield.

Determination Heavy metals Accumulation in Water, Sediment and Fish of Qarasou River

Abstract— The excessive increasing of population and industrializing societies, especially since second half of the 20th century, is caused to appearing new problems about environment pollutions. Heavy metals are some kinds of these pollutions that they are naturally marine ecosystems constituents. Even some of them have a crucial role in the living creatures’ existence, but their too much density causes the endangering of the aquatic creatures’ life. In this investigation, four stations were determined in order to determining the amount of heavy metals including Cu, Ph, Cd, Fe, Zn, and Ni in Qarasou River’s water, sediment and fish. Furthermore, physiochemical parameters (water temperature, dissolved oxygen, total hardness, electronic conduct, SIO2, TP, TN, PO4, NO3, NO2, NH4, TDS, COD, BOD5, and PH) were measured. The results showed that the observed heavy metals in the water of the region relate to Zn, Fe, Cu, and Ni. In the sediments of basin Pb, Zn, Fe, Cu and Ni were seen and the heavy metals such as Zn, Fe, and Cu in the tissue of fish Squalies Cephalus type and Pb, Zn, and Cu in Copeata type were observed. Based on the observations of metals in water, sediment and the tissue of fish, there are Cu, Zn, and Fe in the form of bioaccumulation in the tissue of the fish. The observed results indicated that non biological parameters including Nitrite, Phosphate, total Phosphorous, TDS, COD, Zn, and Fe amount aren’t in complete desirable circumstances and some parameters like BOD5, however they are in normal boundary, their amount is comparatively high.

Effects of dietary supplements of probiotics, synbiotics and phytobiotics on growth performance and carcass characteristics of broilers under heat stress

Abstract- In order to investigate the dietary effects of growth promoters in broilers under heat stress conditions, 256 male one-day old hybrid "ROSS 308" broilers were investigated using a 2 × 4 factorial experiment in a completely randomized design. In this experiment, treatment number is 8 and replications are estimated to be 4. Dietary treatments consisted of: 1-control (without any feed additives); 2-control treatment with probiotic (primalac, 300 mg/kg); 3- control treatment with synbiotic (biomin IMBO, 1000 mg/kg); 4-control treatment with phytobiotic (sangrovit, 200 mg/kg). Heat stress treatments also including: 1-normal heat conditions; 2- applying 39˚C heat were investigated during a 42-days experiment. The traits associated with growth performance (feed intake, weight gain, feed conversion rate) were measured weekly. In 42 days of age, four birds from each treatments group were selected and killed by random; the weight of carcass, bors of fabricious, spleen and length of small intestine were measured. Relative size of these organs was obtained with dividing the weight of bors, spleen, and small intestine by the body weight and multiplying it to 100.The yield of carcass, bors, and spleenthat were under effect of treatment groups were compared with control group. The results demonstrated that average daily weight gain in period of 22-42 days showed significant difference between control and synbiotic treatment; so that, synbiotic treatment had more average weight gain in compare with other treatments. In total 42 days period, there was a considerable numerical difference between control and experimental treatments of synbiotic and phytobiotic. But effect of heat stress and interaction effect didn't have any effect on average daily weight gain. Generally, the results demonstrated that adding growth promoters causes improvement of growth and some of carcass characteristics.

Preparation and evaluation of nanocomposite starch films containing ZnO for extended shelf life of fresh strawberry

Abstract— Bionanocomposites starch films containing ZnO nanoparticles were prepared by casting method from corn starch solutions. The nanoparticles of ZnO were homogenized by sonication and incorporated into corn starch solutions at different concentrations (e.g. 1%, 3%, 5%, and 7% w/w dried starch). Fresh strawberries were then packed in the polypropylene packages covered with these bionanocomposites, to be used as cap of packaging, and stored at 4oC. Microbial stability of the fresh strawberry was evaluated after 4, 8, 12, 16 and 20 days of storage. Dispersion quality of antimicrobial nanoparticle within the polymer matrix films were assessed by Transmission Electron Microscopy analysis (TEM) and the mechanical properties of them were characterized by using Young's Modulus analysis. The results showed that microbial growth rate significantly reduced as a result of using this nanocomposite packaging material by up to 20 days. The TEM results revealed that ZnO nanoparticles with spherical and granular morphology had uniform distribution within starch polymer. Moreover, Young’s Modulus for all of the nanocomposites increased with the increasing filler loading. Consequently, ZnO nanoparticles have the potential as a filler in starch-based films for use as an antimicrobial packaging materials which help to extend the shelf life of fresh strawberry to 20 days.

This study is seeking to develop tourism industry with Tir parks designing standards and the issues of physical and functional aspects of Aftab Derakhshan Sahra complex in Qazvin. The methodology of mentioned study is based on the practical purposes with the origin of descriptive-case study. Data collection is in library and field study mode. The results show that the tendency of people to use Tir parks depends on various aspects such as functional, physical, perceptional, visual, social, cultural, economical, traffic, environmental aspects. Meanwhile, functional and physical aspects contain great portion which are related to some items including: present land uses in the complex, the location of the complex, space syntax, accessibility, local materials and etc.

Considering the present condition of urban green space (intraurban parks ) by GIS (case sample: district 18 of Tehran)

Abstract— Urban uses are considered as the main column and frame of the city so that the cities are assessed according to the functions and services of how to establish them. Green spaces have different functions in the cities specially big and industrial cities among the urban uses. Green space improves the bioenvironmental conditions of the cities from one hand and provides the suitable conditions for citizens to spend their free time from another hand. The public uses cannot provide desirable services for the citizens because of some reasons like the high density of population, disordering of establishment and location, not paying attention to availability radius and population thresholds. This matter I more visible in big cities particularly for uses like the green space ( intra urban parks). Urban green space is so important that the existence of these uses is one of the indices of development of the societies today. The green space of the studied district (district 18 of municipality of Tehran) is considered in analyzing urban green space to study the distribution of these uses within the district. Then the data are analyzed  by the geographical information system (GIS) so that some suggestions can be proposed by the attained results for determining the districts disadvantaged from using public facilities (parks) and directing the responsible to the necessity of paying attention to suitable locating and distribution of green space (intra urban parks) within the district. 

Features of Qajar Era Houses in the Temperate Climate of the Caspian (Case Study: Kolbadi’s House and Sardar Jalil in Sari) 

Abstract—Mansion of Manuchehrkhan Kolbadi is located in Abanbar-e-no neighborhood in Sari ,and was built around 140 years ago in the late Qajar era by the order of Sardar Jalil, a Sardar of army at the time. This monument was registered as one of the Iranian national monuments on October 31st 1998 with the registration number 2148. Currently, it has been turned into the Museum of Sari city. Architecture of this mansion and the house of Sardar Jalil are influenced by Qajar era architecture, having interior and exterior parts taking the climatic and architectural aspects into considerations. The main building of the two mansions in the interior part was built on two and three floors, and a basement and a dais and two-way rooms on each floor. Dais of the second floor is one of the most beautiful rooms of the mansion ,and every part of it recalls the decorative arts practices of Qajar era. Properties of the architectural components of the building such as rooms, chambers, dais, bath, stable, yard , the art used on their windows , sashes and their decorations with colored glass are unique in their own kinds. Over time, kitchen and parts of the servers’ residential units got ruined and now it has been replaced by new buildings. Like most buildings of Qajar era, this building was built with mud, lime, reed mace, stone, glass, ceramics and wood. The building has ceramic roof, false arc, lion head shapes, sash windows and brick façade. This paper applies library research method , and most of its subjects are obtained from people familiar with the building, and are descriptively presented in the paper. People who have tried to understand and introduce Tabarestan were mostly employees of the province’s cultural heritage and crafts organization.

Pathology of urban seismic areas using Inversion Hierarchical Weight Process (IHWP) and GIS; case study: Gorgan

Abstract— Physical components of urban areas such as buildings, open spaces and their physical characteristics like the size of mass, manner and place of settlement, size and appearance and their positions have a determining role in intensity and extent of cities’ seismic vulnerability during an earthquake. Many Iranian cities are located on the areas with medium and high risk of earthquake. Therefore, considering the quality of the elements and physical components of urban areas can dramatically decrease man-made disasters in Iranian cities. The city of Gorgan, with a population  over 330,000 and an area of 3600 hectares in 2011, is one of the cities which are located in earthquake-prone areas with high risk of earthquake. Residence of some 12 percent of the population in time-worn buildings (consisting roughly 10 percent of the whole area of the city) as well as the lack of a pathological zoning (seismic zoning) of the city has made the seismic zoning of the city a crucial issue. In the present article, vulnerability to earthquake was considered through calculation, analysis and combination of factors such as access to medical centers, the ratio of the streets width to the buildings height, (enclosure),  PGA (Peak Ground Acceleration) of the area, building density, population density, land use, the structures quality  and the extent of vulnerability in Gorgan using Inversion Hierarchical Weight Process (IHWP) and GIS. The study showed that the buildings in the southern parts of Gorgan – compared to the other areas – are less vulnerable. Moving from the south to the north, seismic vulnerability increases. It is due to the fact that the north of the city enjoys wide enough streets and  resistant, young buildings.

Waste management options to control greenhouse gas emissions –Landfill, compost or incineration? 

Abstract—Methane (CH4) is predicted to cause as much global warming as carbon dioxide (CO2) over the next 20 years. Traditionally the global warming potential (GWP) of methane has been measured over 100 years. The IPCC’s Fourth Assessment Report (IPCC 2007) warns that this underestimates its immediate impact. Viewed over 20 years it has 72 times the GWP of CO2.

The current study was prompted by concern about these emissions, and by a recent Government policy study in Melbourne, Australia, which recommended composting of municipal waste. The mass composting of waste would reduce landfill gas, currently used as a fuel. This study uses recent information (2006 IPCC Guidelines) with local data to estimate:

- How much greenhouse gas is emitted to the atmosphere from best practice landfill with methane capture Pipes? How much can be captured to use as fuel?

- Is aerobic composting or incineration better at controlling emissions than landfill with gas capture?

A Study of the Possible Solutions for Radon Concentration Reduction in Homes in Order to Minimize Energy Consumption in Ventilation Systems

Abstract— One of the main problems engaging the attention of scientific communities is air pollution especially in indoor areas such as homes. In this regard, radon is one of the most important and dangerous pollutants since various studies and researches have shown that this gas is the second cause of lung cancer after smoking. Aiming to increase efficiency and reduce costs, current buildings have caused a lower quality of the air inside homes. Therefore, an appropriate ventilation system is required to prevent such pollution in order to provide clean and fresh air at an acceptable level. This article tries to study an optimum condition for achieving two important goals i.e. human health and energy saving optimization in ventilation systems.

Abstract— Heavy metals for their poisonous susceptibility in more than permissible level are being considered as a great concern of environment. Metals enter to environment through many ways like industrial activities. In present investigation three unnecessary heavy metals such as lead, cadmium and chromium were measured by spectrophotometry method in muscle tissue of local carp. The mean of lead, cadmium and chromium concentration in muscle tissue were respectively 1.56 0.44, 0.16 0.04 and 0.83 0.11  g/g, and the possibility of potential hazard of consuming this fish was evaluated according to instruction of U.S.A environment conservation organization. The obtained amount of heavy metals concentration in local carp was (0.31 m/g) more than international standards (0.3  g/gwet weight) in 2007 .in addition, according to obtain results the most of daily consumption dose was for lead element.

In present study children more than women were under risk of carp consumption. Nevertheless estimating of potential risk of all elements showed less than 1 for native in habitants which shows that consumption of local carp has no peril for consumers. 

Qualitative and Quantitative Evaluation of Groundwater in Isfahan Najaf Abad Study Area

Abstract— In this paper, quantitative and qualitative changes in groundwater of Najaf Abad Plain were evaluated. The quantitative assessment based on data obtained from 48 observation wells showed that the average groundwater level in this plain declined 24.25 meter from 1994 to 2012. Then, the average groundwater level declined averagely 1.28 meter per year. Zonation of the declines in this plain suggested that maximum drop is observed in intermediate aquifer zones. This decline even extends to 85 meters. The minimum drop rate equal to zero was observed in Zayanderood margins. Fifteen operated wells were analyzed physicochemically to evaluate chemical quality of the study area. These evaluations included measuring pH, total hardness (TH), total dissolved solids in water (TDS), electrical conductivity (EC), magnesium (Mg), calcium (Ca), sodium (Na), potassium (K), chloride (Cl ), sulfate (SO4), bicarbonate (HCO3). Comparing the results with drinking water quality standards of the World Health organization (WHO) revealed that many water samples could not be categorized as drinking water. Hydro chemical type and profiles using Piper diagram showed that dominant type of the study area is categorized as bicarbonate type with sodic profile. Wilcox diagram results and combining sodium absorption ratio (SAR) and electrical conductivity (EC) indexes showed that only 66.6 of the samples are suitable for agricultural purposes.

The analysis of organizational education and training system from economic view and human capital and its role in sustainable development

Abstract-The social organizations are some of the foremost phenomena at present time. Many requirements are met by organizations in modern world. By the aid of their resources including technology, information, financial sources, and human capital the organizations meet the social requirements. The human capital of the organizations is deemed as the paramount and most effective organizational sources since other sources are perishable but the human capital can be developed. To realize this objective, the reviewing scientific method has been employed. The results of this investigation indicate that the growth and excellence of human capital in the organizations might be only possible through organizational education and training. This issue suggests that organizational investment in growth and development of human capital is more efficient than investment in physical and equipment- related dimensions and it contributes the organizations in realization of their goals and growth and development of organizations will help to national growth and sustainable development from various dimensions. Thus, organizations should change their attitude from equipment- centered view to education and learning- centered approach. Of course, fulfillment of this important point requires serious investment in the field of training and education.

Site location of temporary accommodation after the earthquake using GIS: A Case Study of Tehran Municipality's District 5

Abstract: Studies in the field of the post-catastrophe management shows that in most cases, especially in urban and more developed areas, construction and reconstruction after the event will be complicated and slowed down. This is due to several factors such as complexity, remains of the damaged building elements, the level of area development, administrative construction regulations, too many homeless people, basic living standards, etc. At this stage, supplying permanent accommodation after the temporary settlement is a major problem. One of the most important problems which is considerable after a quake for responsible crisis management organizations is choosing a suitable and safe place as a temporary residence for catastrophe-stricken people. Geographical Information System, due to its unique locating efficiency can be used as a proper tool for logical locating in the\ hands of decision makers. This article tries to study district 5 of Tehran city as a sample area in choosing trend of proper places for residing quake-stricken people soon after the event. So, primarily the conceptual sample was designed, and then various data needed to establish a data base including facilities, services, vital networks information, and also natural features and characteristics of the area were collected and put in a similar framework of numerical properties. The data, then, analyzed comprehensively using Geographical Information System. At the next stage, the standard features of locating emergency residing quake-stricken people data were entered into the location data base and researching as well as extracting the results were done based on the mentioned information. Considering all standards of locating a proper place as a temporary residence for the quake-stricken, such as vital networks of power, gas and others and also natural conditions of the area, the results proved that the best places for temporary residing operations are open areas of some parks in this district.

Environmental impacts of rural tourism

Abstract— Tourism in an environment that consists of human and natural characteristics of the human environment and the processes of economic, social and cultural. The natural environment of plants, animals and their habitat will be formed. We can distinguish between the human and natural environment. Tourism can be an important form of human activity has important effects. The effect on the target area, where tourists and the local environment, economy, culture and society interact very evident, therefore this study was to describe the environmental impacts of tourism, although tourism issues are multifaceted and often "a set of economic, social and environmental.

In this set of solutions and positive and negative impacts of tourism on the environment is studied. This descriptive study included the sustainable tourism, especially rural tourism development in the region can be achieved by considering the relationship between the three components of the environment is tourism. Tourist destination and host society considered, this relationship can be complex, dynamic, constructive or destructive. Therefore the aim of establishing sustainable rural tourism moderation and balance with long-term conservation of these three components is tourism. Since there is a close relationship between economic and environmental policies aimed at achieving the goal of a social or economic impact is inevitably environment if this policy is not to comment, if the root causes of environmental degradation and economic functions, the solution is the same.

Analyzing role of agriculture in food safety and using natural sources in world countries (international approach)

Abstract—Food safety determined human’s history. The world population will increase to 9 billion people until four decades later and the predicted required food will increase to two times more than this. This increase will have more pressure on natural resources such as water, soil nutrients materials. The gap in our science about world capacity for production of inputs from one hand and the need to sustainable production of crops and food safety from the other hand explains special paying attention to producing food inputs with optimal production. Limitation of soil, water, food and energy suggest that we need a new predicted solution in local and global. Growing requested of food material, combined feed for animal shows that for changing potency of power in earth management we need to improving productivity of crops and better using of resources. Therefore agricultural engineering has a major duty to these projects.

A Study on the New Towns’ Rate of Success and Performance, and Scrutinizing their Obstacles and Problems.

(Case Study: Sadra New City)

Abstract— Cities and towns are dynamic systems whose shape and performance alters gradually. Factors as industrialization, migrations of villagers to cities according to land reforms, successive droughts, deceptive urban attractions and villages’ repulsive agents, has cause daily increase in the cities’ sizes and numbers and also has altered their shapes and performance. This process has resulted in the emersion of metropolises as Tehran, Shiraz, Isfahan, Mashhad and Tabriz. The high density of population and activity in metropolises has lowered the citizens’ life qualities and caused economic, social and environmental problems. This has resulted in the construction of new cities with the purpose of decentralization of the mother cities. In order to approach to this purpose, prospections have been made about the attraction of population and occupations. When talking about new cities, automatically our mind goes towards utopias and an aggregation of ideals in these cities; cities which are optimum in their design, construction and execution and are accordant to innovative urban thoughts; and all citizens can live in safe spaces having facilities, sustainable neighborhood centers, powerful social centers with a calmness which has been predicted in the attitude of such cities. A question about if Iran’s new cities have such qualifications, arises here. This article is to survey these cities’ aims and reasons of failure, by studying their process of alterations, and finally evaluates Sadra new city as a case study.

A Study on Spatial - locational distribution of health care use, by GIS system

Case Study: Hospitals in Kerman

Abstract: Rapid growth of population in cities, especially large ones, has increased the demand for public goods and services. This increase in population is causing problems in providing services to these individuals. In most cities, the lack of appropriate space allocation and optimal placement of structural elements and services, particularly health centers (hospitals) and the number of affective factors in locating the centers has caused the increase of urban and citizenship problems. The need to plan for humanity's urban centers, which are the cities, is more than ever. And due to this lack of documented system and careful planning of cities, this issue has created a lot of problems. As one of most important problems we can mention the decrease in various per capita lands in the city. The places for treatment facilities are one of the main uses, and allocating space to this user is an important issue for planners and urban planning. Due to the sensitivity of the usage and its direct relationship with the families; how to allocate space and layout optimization is very important for therapeutic use. In Kerman, as the Province and also one of the metropolises of the south, the high urban population density, traffic, lack of adequate access, lack of land, lack of proper distribution of medical applications space has made this survey more urgent. We aimed to investigate the spatial- locational distribution of healthcare facilities (hospitals) and to identify underserved areas in the Kerman city, according to the locational standards and criteria.  The research method is field, descriptive - analytical, the data collection is done using GPS, and for data analysis Excel, GIS were taken into account. The results show that the spatial and locational distribution and health centers in the city of Kerman, unlike other urban centers of health, haveLess adherence to laws that classify urban neighborhood as the area, region and … .In general, the region number onehas a suitable situation while other areas of the city are facing shortages.

Zoning Hormozgan’s tourism comfortable climate using the (TCI) index

Abstract—Tourism is one of the largest industries in the world and climate, as a source of tourism, plays an important role in this industry, so that more tourists determine the time and destination of their travel according to climatic conditions. In this study, using Mieczkowski (1985) Tourism Climate Index (TCI) and the climatic data from 9 synoptic stations, the climatic tourism in Hormozgan province has been evaluated. This index has systematically evaluated the climatic conditions for tourism using average maximum monthly parameters of daily temperature, mean daily temperature, minimum relative humidity, mean daily relative humidity, rainfall (mm), total sunshine hours and wind speed. An Analytical-descriptive method has been used for this study with the objective of qualitative evaluation of Hormozgan province based on comfort and bio-chemical aspects, as well as determining a tourism calendar based on the TCI index. For this purpose the homogeneous climatic data of one statistical 15 year period from the 9 synoptic stations of the province have been collected, and after processing and analyzing them with Excel, and also creation of a data bank, the TCI index have been calculated on a monthly basis for the various stations and by using the GIS method a TCI map, based on DEM, has been drawn for each month of the year.

The results show that climatic index of the Hormozgan tourism in the month of December and March have scored the highest points, therefore they have the best climatic conditions for tourism. On the other hand July and August, with the lowest scores, are the most inappropriate months for tourism activities.

Study of factors that affect flooding in order to reduce natural hazards in areas Yamchi Dam Using by GIS

Abstract—Flooding obliterates facilities and causes physical damage and disrupts utilizing of highways and railways. In addition, flood is a barrier for effective drainage and economical use of land for agricultural and industrial purposes. Due to the high current or river runoff in catchment, huge erosion occurs across the basin and eventually creates serious problems in downstream of the falls which is caused by settlement and accumulation of sediment. Upper catchment of Yamchi Dam is the Sub Basin of Balkhly River in Ardabil which is located on the southern hillsides of mount Sabalan. Due to the topographic and climate condition of this basin, flooding is vulnerable here; and this causes damage to rural dwelling sites, farm lands, and communicative pathways. The occurrence of this phenomenon in one hand culminates into soil eroding increasing and soil exacerbation resources, in the other hand forces filling in Yamchi Dam reservoir. Therefore the purpose of this study is to identify factors that contribute to flooding in the mentioned as to approach above purpose factors such as slope, aspect, and lithology, distance from waterways and precipitation were examined as effective factors in which contributes to flooding; then their data layers in  (GIS) and Arc MAP were prepared and  as well as geometric factors such as  shape, area, and circumference, basin height and rectangular area were assessed and  investigated results suggest that following  basin study is  prone to devastated floods that mainly occur in spring. The results also showed that interfered factors in the flooding basin consecutively include slope and aspect, waterways, rainfall, lithology and the time of concentration and the time of delay. Because basin shape is round, so it shows more reaction which is attributed to shower and flood occurrence. The length of basin waterway is also high, which is indicating a high density of streams and the possibility of flooding occurrence is high, therefore, managerial and protective measurements should be taken in the basin.

Study of affect factors on flooding and crisis management in Yamchi Dam using by GIS

Abstract—Human life since the beginning up to now has always been associated with the risk of natural disasters. Due to climate variability and temporary instability and destructive condition of Iran, yet is one of the countries that are more vulnerable to natural disasters, that flood is one of the most serious ones. Upper catchment of Yamchi Dam is the Sub Basin of Balkhly River in Ardabil which is located on the southern hillsides of mount Sabalan. Due to the topographic and climate condition of this basin, flooding is vulnerable here; and this causes damage to rural dwelling sites, farm lands, and communicative pathways. The occurrence of this phenomenon in one hand culminates into soil eroding increasing and soil exacerbation resources, in the other hand forces filling in Yamchi Dam reservoir. Therefore the purpose of this study is to identify factors that contribute to flooding in the mentioned as to approach above purpose factors such as slope, aspect, and lithology, distance from waterways and precipitation were examined as effective factors in which contributes to flooding; then their data layers in  (GIS) and Arc MAP were prepared. The results also showed that interfered factors in the flooding basin consecutively include slope and aspect, waterways, rainfall, lithology, and the time of concentration and the time of delay. Overviewing the basin flood statistics confirms the fact that the majority of flooding occurrence in the upper basins of the Yamchi dam has happened in the months of April and May. Due to the floods occurrence in the following months some factors such as rainfall increasing, snow melting in the upper elevations of the watershed and poor vegetation in the basin are involved in this case. Therefore, attention to these issues and providing practical guidelines in the area may reduce the statistics of the future flooding.

Biogas production yield of anaerobic baffled reactor in low pH and HRT

Abstract— The purpose of this research is to examine the performance of anaerobic baffled reactor (ABR) in two different operational conditions with focus on biogas production. For this purpose, a pilot with 6 compartments, having overall net volume of 60 liters, was used and inoculated continuously with dairy wastewater. After start-up, the average COD removal efficiency of 82% was achieved for 36 hours hydraulic retention time (HRT). In first step, by decreasing HRT to 18 hours, the overall COD removal efficiency and total biogas production yield were reduced 5 and 24%, respectively. Here, the ratio of methane to carbon dioxide content of biogas was reduced from 1.6 to about 1.14. In the second step, in HRT of 18 hours, the influent pH was reduced below 6 instantaneously. The experimental results show that the COD removal efficiency and biogas production yield were reduced dramatically about 46 and 82%, respectively. As a consequence, the M:C ratio was dramatically decreased to 0.14. It can be concluded that ABR with 6 compartments is rather a robust technology for dairy wastewater treatment and biogas production in low HRTs. However, it seems more susceptible to pH reductions. Therefore, for a well energy recovery, it obviously requires an equalization or pre-treatment unit as neutralization.

An Overview of Thermochemical Methods for Hydrogen Production from Biomass as a Clean Fuel

Abstract— Fossil fuels that supply the major part of energy demand of the world are being depleted fast. Also Their combustion products cause environmental impacts and global problems such as global warming as a result of greenhouse gases emissions that follows with melting arctic ices, raising the ocean's level, and forest burnings so that after industrial revolution and increasing growth of machines and specially after discovering and extraction of oil and gas reserves, greenhouse gases emissions have increased significantly so that many of scientists and engineers believe that substitution of fossil fuels with clean fuels that come from renewable resources, is one of the best ways to solve these problems. Another important issue is energy security and availability. Hydrogen has attracted a lot of researcher's attention to itself as the most abundant element in the world that releases the highest energy during combustion (2.8 times higher than that of gasoline). Its abundance and minimum environmental impacts during conversion to power, are the most important criteria that make this element, the key energy carrier of future. Since hydrogen can be produced from abundant renewable resources, it is expected that the use of hydrogen as an alternative fuel will increase dramatically. In this article we study about thermochemical methods of producing hydrogen from biomass as a renewable carbon-containing resource, affecting parameters of the process and the challenges of using this energy carrier.

Numerical Simulation of Flow Field around a Darrieus Vertical axis wind turbine to Estimate Rotational wakes Size

Abstract: Due to the increasing energy cost and reducing fossil resources, also with respect to environmental pollutions, sustainable energy usage is inevitable. In the last decades wind power is allocated to a particular share of sustainable energies. Design and optimization of wind systems requires aerodynamics analysis. Computational fluid dynamics is a guaranteed method for aerodynamics analysis of wind turbines. In this work at first we introduce briefly Darrieus vertical axis wind turbines and discussed their advantages and disadvantages compared to the horizontal axis wind turbines. Then tried to use a computational fluid dynamics method to simulate flow field around the Darrieus vertical axis wind turbine with three straight blades that use NACA0016 airfoil as profile of blades. To do this, we used RNG K-ε turbulence model to solve RANS equations of fluid motion. Simulation has been performed for three values of the rotational speeds. Velocity distribution of wakes is obtained in some horizontal directions.

Significant bias may exist in previous relations that neglected the influence of σv’.The results showed that the proposed empirical formula can be used as reliable relation in the northeast of Iran.

The Role of Spectral Indices in Identification and Preparation of Soil Salinity Map of Bare Lands and Vegetations

Abstract—Spatial and temporal  variation of soil salinity is large, therefore mapping the salinity is difficult. Costs of remote sensing data are less, so they are widely used. But extant studies generally study arid soils (bare) and less point to  halophyte plants  and their role as indicators of salinity. This paper aims to investigate the relationship between soil properties, electrical conductivity of the saturation extract (ECe) and the spectral reflectance of vegetation species and bare soil, to offer a method to provide salinity mapping using remote sensing. Various vegetation species and bare soil reflectance have been measured. Spectral Response Index (SRI) for bare soil as well as soil with vegetations have been measured using the Normalized Difference Vegetation Index (NDVI) and Soil Adjusted Vegetation Index (SAVI). (ECe), texture and  organic matter of soil samples were determined. Landsat5 imagery have been used to calculate Spectral Response Index (SRI). The correlation coefficient between (SRI) and soil salinity were obtained and a model was presented for soil salinity prediction. EC map was estimated using the proposed model . Correlation between SRI, and EC was calculated which was higher compared to other models (0.97). The results show that salinity map obtained from the model is in the highest level of compliance with field findings (0.87).

Studying of spatial characteristics of groundwater quality by using the factor analysis method and GIS (Case Study: Coastal Plain aquifer Surrey - Neka)

Abstract—Ground water in coastal areas is the main source of water for domestic and agriculture use. Water resources in these areas where are fertility and populated are faced by many biological challenges so understanding different effective on ground water quality factors can help to have a optimal management of the aquifer. The aim of this study is to have a spatial investigate in the qualitative properties of Sari, Neka aquifer. In this study, a combination of the two methods, factor analysis and geostatic was used to spatial analysis of groundwater quality. The results of factor analysis revealed three factors. Cl, Na, SAR, EC which represent the salinity in first factor, bicarbonate, magnesium, calcium and TH indicate water hardness in the second factor and potassium and PH reflect the impact of the geological factors and increasing in use of fertilizers and in the third factor. Finally, with the scores obtained from factor analysis we planned the spatial distribution of groundwater quality by kriging model. The first factor increases in some parts of coastal line and southern parts, the second factor increases in southern and the third factor increases in parts of central and coastal areas. According to the results, the effective factors on the quality of the aquifer can be agricultural land use and management, development of residential areas, salty water intrusion into aquifers and geological factors. 

Using Inversion Hierarchical Weight Process ”IHWP” Analysis to Identify Security Levels in Kerman Neighborhoods Based on Physical Indices

Abstract— Security in Kerman was studied from the viewpoint of physical factors that underlie crime. This article analyzes security levels in some neighborhoods of Kerman by considering physical indices underlying crime. The descriptive-analytic method was used and most of the information and data was obtained through on-the-ground observation and understanding of the situation in the neighborhoods. The six indices of openness of the space, compactness of texture, vegetation, lighting of the streets, urban furniture, and quality of the streets were used to analyze security levels. The modified model based on entropy weight was then employed to calculate the influence coefficient of each parameter of security and the technique of inverse hierarchical analysis was used to determine the actual and the ideal levels of quality of each neighborhood. It was found that the indices of lighting and quality of the streets enjoyed the highest influence coefficient and the index of the openness of space the lowest. Moreover, of the 13 studied neighborhoods, the Imam-e-Jom-e neighborhood enjoyed the highest, while the Allahabad and Taherabad neighborhoods, that were developed in the unstoppable urban sprawl, were mostly located on the outskirts of the city, and were the places where mainly people of low-income levels and non-natives lived, had the lowest quality.

The study of sustainability indicators in the  countries of the polluted cities of the world compared to countries with high per capital income

Abstract: Due to increase in the economic activities , cities have ended up in evacuating the environmental resources and the increased pollution of the earth which is the most crucial factor to affect environmental imbalances . Of  these most important pollutions which has a main role in the rise of the earth temperature is air pollution . What matters is the relationship between pollution and the economic , social , and environmental development . The present paper deals with the study of the substantial  indicators in the countries having the most polluted cities in the world. Three basic indicators  ,  namely  economic ,  social ,  and   environmental developments taken from the variables within reach are studied. This survey is taken in comparison with the countries that contain .the  highest national  gross  income  per capita . The  population under  study  includes  countries  with 50  world  polluted cities marked  by  the  World  Health  Organization  as  first  rank  in pollution in 2014 and countries which have high national income. To this  organization , the pollution  index  is the appearance of 10 micrometers or less particles suspended in the air. The data is gathered through library study and  the    updated    in  formations  are   from   the sites of Word  Health Organizations , the International Agency of Environmental Protection , World Bank , and the Guinness Book of  Records. The results  indicate  a  substantial deep gap   between countries containing the polluted  cities  and  countries   with   the highest word income per capita. The negative correlation between the  amount of  pollution  and sustainability  rate  in   the   polluted. countries of the world is indicative of lacking a smart  development compatible  with  the countries  environmental  conditions.

Look at the situation in Iran for Migration With an emphasis on the city of Ardabil

Modeling of PEM fuel cell with reformate feed

Abstract—Fuel gas containing Carbon monoxide severely degrades the performance of the PEM fuel cell. To evaluate the effects of such feed, a two-dimensional, single-phase and non-isothermal carbon monoxide poisoning  model for PEM fuel cell has been developed based on the conservation of mass, momentum, species, electrical charge and energy as well as adsorption, desorption and electro-oxidation kinetics. These equations solved with finite element method and good agreement seen between modeling and experimental results. The simulated results show that increasing the anode overpotential, increases the fractional coverage of catalyst surface by Hydrogen. In addition, inert gases like CO2 have too low effect than CO on polarization curve.

Modeling of photovoltaic panel using datasheet parameters

Abstract—the growing number of the PV panels that share power supplying all over the world makes it essential to have a model of panels to be utilized in further analyzing. In this study a single diode model, which is simple and accurate, is created for PV panel. The parameters that need to be extracted from datasheet specification in modeling of PV panel include photovoltaic current (IPV), diode reverse saturation current (I0), diode ideality constant (a), series resistance (RS), and parallel resistance (RP). For simplicity some authors eliminate the parallel resistance or both the series and parallel resistance, but these resistances have significant effect on PV model accuracy and its better not to be eliminated. This paper proposes an iteration procedure to estimate the amount of these resistances by changing the values of resistances to match the maximum power point with maximum power point voltage. Two different commercial PV modules with different technology (monocrystal and multicrystal) are selected and modeled in MATLAB/ SCRIPT. Their predicted output values at nominal operating cell temperature (NOCT) provided by proposed model are compared with the NOCT parameters values provided by manufacture's datasheet and their relative errors are calculated to validate the proposed model.

Chemical and Biological Characterization of Animal Wastes in Livestock Industry and Offering Appropriate Management Solutions to Collect and Dispose of Them (Case Study of Dasht-e Azadegan Dairy Cattle Farm)

Abstract— One of the sources of waste production is the waste produced by the livestock industries. Animal waste contains nutrients  such as nitrogen , phosphorus , potash , high percentage of organic matters , and also pathogens transmitted from animals to humans , which not only do pollute the environment in case of waste mismanagement, but also endanger public health and sanitation. This research aims to investigate bacterial properties and the amount of fecal coliform and chemical properties and the total amount of produced waste per each head of cattle with regard to their weight and the average mean of daily produced waste of the studied dairy cattle farms and also to offer management solutions for their optimal disposal. In this connection, chemical properties such as percentage of nitrogen, phosphorus, potassium, calcium per dry weight , BOD, pH , C/N ratio, total and fecal coliform rate were measured. Pathogens such as Escherichia Coli, Salmonella, Shigella, Ascaris , Balantidium Coli , Tina Saginata were identified. The fecal coliform was measured as 26x109 MPN/g per dry weight. The amount of fecal wastes pr head of cattle with regard to the weight of the cattle and total amount of animal wastes was calculated in Susangerd and Hamidieh dairy cattle farms. The studied samples are Holstein dairy cows. The average amount of produced waste per each head of cow weighing 240 to 365 kg is 12.9 to 19.7 kg per day. The total amount of waste produced in Susangerd and Hamidieh dairy farms is 466.3 and 973.36 kg per day respectively. In order to compare the data, spss software was used. Scraper system and tractors equipped with blade were used to collect the waste. With regard to the climatic conditions and the soil type, biogas method and drying the compost indoors by dryer are suggested for the waste disposal.  

Advantages, Disadvantages, Obstacles and Strategies for Renewable Energy

A Survey on Removal of Cadmium from Aqueous Solutions using Activated Carbon of Almond-Shell

Abstract: Cadmium is one of the heavy metals which is entered to water resources through different ways such as industrial, home and agricultural wastewaters or as a result of unhygienic withdrawal of urban and industrial wastes. Surveys in some regions around pollutant resources show that surface waters or underground waters is contaminated to cadmium in “0.1 to 1” mg/lit [1]. Activated carbon with nano pores is a green technology for separation of poisonous material in environment. The aim of this research is to determine the level of cadmium absorption by activated carbon of almond-shell in concentration of “20 ”, “50” and “100” per part million (ppm) and different insolubility times from “15 to 120” min. Experiments for determining isotherms were assigned discontinuous in different concentrations and different amounts of biological activated carbon (from “0.1 gr to 0.3” gr) and the cadmium with desired PH. Measurement of cadmium performed by atomic absorption device and based on the standards.  Observing the research results and the PH regulated on “6” , increase in primary concentration of cadmium resulted in increasing of absorption level and also by elapsing the time, absorption level was raised and the maximum absorption on “61%”  was happened in time range of “120” min. The results indicate that bio absorber containing sodium alginate containing activated carbon prepared from almond shell is new adsorbent for the removal of cadmium ions from aqueous environments.

Applying the Knowledge of Operational Research in Agricultural Mechanization

Abstract—Applying any technologies that leads to increase productivity in the agricultural production is interpreted as mechanization. In another definition, the mechanization is the use of technology in agriculture in order to achieve stable development. If the latter definition is considered as the basis, it can be concluded that by using the scientific achievements which is considered as a type of technology and is accelerated the development of mechanical agriculture; steps have been taken to expand mechanization. One of these scientific achievements is the knowledge of Operational research. This knowledge which is one of the branches of applied mathematics is used to facilitate decision making based on scientific criteria and constraints. In the agricultural sector in which there are various restrictions such as weather conditions, economic and social issues; taking advantage of this knowledge can help to solve problems and make the right decision. This paper introduces knowledge of Operational research and its application context in agricultural mechanization.

Studying the effect of freezing on artificial ripening of ‘Mazafati’ date fruits in Khalal stage

Abstract−The palm bunch wilt or date bunch fading disorder (fruit shriveling and desiccation before ripening) and fruit abscission due to high weather humidity or strong local winds blowing have forced the palm owners to harvest the date fruit yield in Khalal stage and ripen it artificially, so that they may reduce the loss to a remarkable extent. The present research studies the application of the method of freezing and keeping refrigerated for artificial ripening of date fruit at Khalal stage. This experiment was carried out in a factorial manner and in form of randomized complete block design. The experiment included two factors that are 1) ripening stage in three levels (Khalal, semi-ripe, and Rutab), and 2) storing time in three levels (45, 90, and 135 days). After being stored in the freezer, date fruits at Khalal stage were taken out of the freezer in the related times and required tests in regard with fruit water content, pH, reducing sugar percentage, total sugar percentage, Total Soluble Solids percentage (TSS), and titratable acidity were performed on them in the laboratory. Results indicated that, after keeping fruits refrigerated, percentages of Total Soluble Solids percentage and total sugar percentage were significantly increased over time. Percentage of reducing sugar was lower in Khalal stage in compare to Rutab stage. Acidity and moisture content in Khalal stage were higher than in Rutab stage. Color of fruits in Khalal stage stored in a refrigerated condition turned darker over time, and the fruits tissue became softer, to the extent that they were marketable after 45 days. The more the storage time is prolonged, the more the fruits turn darker and softer. However, the quality of the fruits stored and marketed in this method were as the same as the newly-picked fruits. 

Kat, an Architectural Invention for Temperature Adjustment in City of Dezful: Economic Architecture

Abstract: One of the outcomes of the ever growing technology and urbanization is the incessant flow of new architectural styles expressed in different structures and forms we have been witnessing every day. The question arises as of the mass of the architectural structures and monuments which one could be characterized and introduced as a sustainable and durable work? Most of the traditional buildings are characterized as relatively sustainable architectures, since in their construction a good tradeoff could be achieved for such factors as culture, originality, climate, local materials, and functionality. Sustainable architecture at each time involves harmony with environment with the least damage to nature, maximum energy saving, roots in local culture, as well as a proper response to overall functional requirements of readability and unambiguity. This study explores “Kat”, a unique structure developed in an organic fashion along parts of the Dez River near Dezful city. The research is conducted based on a descriptive survey design where the required data is gathered through field observation, interview with local people, and library research. Our findings underline the highly adaptive and comfort seeking nature of human being which, in our case, is manifested in Kat thank to the benevolent presence of the adjacent natural rocks on the riverside. This place while serves as a resort, it satisfies the sustainability conditions privacy, introversity, dynamism, and economy of the structure) without adverse consequences for the natural environment.

Development of an Efficient in Vitro Micropropagation Protocol for Medicinally Important Plant Stevia rebaudiana Bertoni

Abstract: The current situation of medicinal plants and increasing demand of plant derived drugs suggest an immediate need to conserve our medicinal plant resources. Stevia rebaudiana is a valuable medicinal plant species and it is being used for the treatment of diabetes. Currently, there is a high demand for raw material of this medicinal herb due to ever increasing diabetes disorder among the population. It is becoming an endangered species due to its infertile and small sized seed. The methods of vegetative propagation are not efficient to save this rare plant.  In order to meet the increased demand an efficient in vitro propagation of stevia rebaudiana was established. The present study attempted to develop in vitro micropropagation protocol for the important medicinal plant Stevia rebaudiana Bertoni. Shoot tip and node segment of healthy plants from natural condition were used as explants for direct organogenesis. Different concentrations of cytokinin and auxin both alone were used. The results showed that shoot tip explants was far better than node explants. The highest percent of shoot induction (97.78 %) and shoot length (14.3 cm) shoot were obtained in full strength MS media and ½strength MS media from shoot tip explants. The maximum of shoot length (14.6 cm), number of leaf (24 Leaves per explants cultured) and multiple shooting rates (14.4 shoots per explants cultured) were obtained in MS medium fortified with 1.0 mg/l BAP from shoot tip explants. Highest number of root (6.4 roots per shoot cultured) and root length (5.2 cm) were observed in ½strength MS media fortified with 0.5 mg/l IBA. In this study physiological effects of different strengths of Murashige and Skoog (MS) medium and growth regulators cytokinin (BAP, KIN and TDZ) and auxin (IBA) on invitro Proliferation of stevia were investigated. Rooting was best achieved on half strength MS medium augmented with 0.5 mg/l  IBA. The plantlets regenerated in vitro with well-developed shoot and roots were successfully established in pots containing garden soil and grown in a greenhouse with above survival rate. The methods of vegetative propagation are not efficient to save this rare plant. Therefore protocols developed in present investigation are not only useful for its large scale propagation but also conservation of germplasm.

Effect of Salinity Stress on Germination Properties in Tomato (Lycopersicon esculentum L. var Chef fallat).

Abstract— The response of tomato genotype Chef fallat against five salinity levels (distilled water as control, 25, 50, 75 and 100 mM) were studied at germination and early seedling stages. An experiment with conducted by using a completely randomized design (CRD) with three replications. Shoot and root length, shoot and root fresh weight, seed vigor, mean germination time, germination percentage and rate measured 14 days after germination. Results of data analysis showed that, there were significant differences between salinity stress levels for all investigated traits except mean germination time. Results of data analysis showed that, indicate that the maximum germination percentage during the test was related to the observer 25 mM and control (Distilled water) treatment. the maximum germination percentage at day 14, with an average of 98.76 and 97.66%, were related to the Distilled water and 25 mM treatments. The maximum root length, at day 14 of the test, was from the 25 mM treatment, which did not show a significant statistical difference with the control (Distilled water) treatment. In the entire measured traits, we achieved better results from the control (Distilled water) treatment and 25 mM treatments, in comparison to the 50 mM density, which indicates that the Chef fallat tomato genotype could grow properly in low-saline conditions, but this growth faces an extremely significant decrease with the increased salt densities.

Performance Evaluation of Optimal Locating and Sizing of DGs as Hybrid Systems 

Abstract— Distributed resources can provide power (active and reactive) as hybrid system in transmission and distribution networks. These sources show desirable effects such as improved power quality, improved voltage deviation, reduced peak shaving and losses, increased reliability, etc in the transmission and distribution networks. To achieve the desired effects listed above, optimal location and size determination has a particular feature. Lack of proper placement of the hybrid distributed generation system in the network may increase the errors causing voltage fluctuations and may increase losses. Therefore, the technical evaluation as well as qualitative and quantitative analysis of a wide range of factors affecting network security and performance is essential in this case. This paper applies Binary Genetic Algorithm (BGA) for locating DG (Distributed Generations) to reduce losses and improve voltage deviation. Then, DG sizing as a hybrid system by PSO algorithm is done to reduce the net cost of the equipment. This approach is carried out on three IEEE networks distribution buses 9, 13 and 34 and, the best location and the optimal size is presented according to the objectives.

New and Sustainable methods and Approaches in protecting Natural Environment

Abstract— Natural environment refers to all environments in which life exists. It encompasses a set of external physical factors and living organisms that are interacting with each other and influence the growth, development and behavior of the organisms. Natural environment means combining different in science and includes set of biological and environmental factors in the form of natural environment and non-biological ones like physical and chemical factors that affect and are affected by the life of an individual or a species. Nowadays, this definition is related to human and his activities and the natural environment can be summarized as a set of natural factors of the Earth like air, water, atmosphere, rocks, and vegetation that have surrounded humans. In the 21st century, protecting the natural environment is known as one of the 8 goals of the century developments and considered as one of the 3 bases for sustainable development. In this regard, mechanisms like emphasis on idealistic approaches, i.e. diminishing realistic trend and resorting to critical modernistic approaches and International Environmental Law are thought to be among methods that guarantee the new approach of environment protection.

Ecological roles of anammox bacteria

Abstract-Types of bacteria such as anammox bacteria obtain their energy for growth from the anaerobic oxidation of ammonium with nitrite to dinitrogen gas.Because of thisfeaturehas made anammox bacteria very valuable for industry where they are applied for the removal of nitrogen compounds from industrial and domestic wastewaters.Anammox bacteria are also important in nature where they contribute significantly to oceanic nitrogen loss. Further, anammox bacteria have similarities to both Archaea and Eukarya, making them extremely interesting from a cell biological perspective. The anammox cell does not conform to the typical prokaryotic cell plan: single bilayer membranes divide the anammox cell into three distinct cellular compartments that possibly also have distinct cellular functions. The innermost and largest compartment, the anammoxosome, is the location of the energy metabolism. The middle compartment, the riboplasm, contains the nucleoid and ribosomes and thus has a genetic,information processing function. Finally, the outer most compartment, the paryphoplasm, has an as yet unknown function.

In this descriptive-analytic study, the survey methodology and the SWOT management model were implemented to identify the factors affecting sustainable development of urban tourism in Nourabad, Mamasani as well as study the advantages, disadvantages, and possible threats that might exist in this regard.  The results show that due to its various natural and historical tourist attractions, Nourabad has a high potential for sustainable development of tourism.

A Comparative Study of Concepts, Principles and Traditional Methods of Iranian Architecture and Urbanization in the Sustainable Architecture and Urbanism    

Abstract: The study of Iranian past architecture and its education in a proper manner corrects inaccurate and ungracious contemporary architecture ¬and establishes a suitable method. Any kind of architecture is organized and can be considered as an organizer of the space of human environment. The purpose of this study is understanding the past events  and learning about the essence of the basic architecture ,i.e. space. Something without time aspects time and urban space fulfils the same essential essence, especially in spaces that have gradually formed during history. Architecture of ancient land of Iran is an interconnected chain of experiences and values that have been continued from thousands of years a go by artists, architects and Iran people from one generation to another. During this gradual evolution, Iranian architecture and urbanism at all times have been formed with a focus on the cultural, religious, social and natural infrastructure of ¬ that time and a variety of styles of architecture and urbanism created in different parts of Iran because of various ethnics, religions and climate conditions. Simultaneous construction of Iranian buildings in cities ¬and villages ¬ at different times and places with social, cultural, religious and environmental infrastructures cause Iranian architecture always meet the material and spiritual needs of the people. Architecture and urbanism in central and desert regions of Iran which completely reflects traditional Iranian architecture and urbanism, is mostly in harmony with cultural, religious, social and natural infrastructures. There is a close relationship between architecture and city and human and nature which show the existence of sustainable concepts and features in Iranian architecture and urbanism.  This inspires Iranian and even non-Iranian contemporary architects. However, globally the issues of greenhouse effect, urban traffic, land congestion, urban air pollution and population growth have created undesirable effects on quality of life in cities. These issues cause the subject of sustainability of cities to be at the top priority.  In this study, in addition to a comparative study of the concepts and features ¬ of sustainable architecture and urbanism, the concepts and features of architecture and Iranian traditional cities are investigated. The result of this study is to achieve specific ¬shared features between the two studied categories.

Geopolitical interaction and international law of energy  

Abstract—If we knew Geopolitics as the complex relations of power in the international system based on political geography, economy and culture, energy as the primary source of human activities in all aspects of life has an important role in this framework. In contemporary international relations, accurately mapped geopolitical interaction with energy can be put many opportunities for decision-makers and decision makers of a country's foreign policy. On the other hand, the international law of energy as a relatively new field in the interaction with the geopolitics formed and developed. Exploration, extraction, energy transfer, finitude of fossil fuels resources and the emergence of environmental problems, has created a new discourse in international relations. Also, the sustainable development and environmental protection, the use of fossil energy carriers should be replaced with renewable energy sources such as wind energy, solar energy, geothermal energy, biomass energy and etc, is the beginning of a new geopolitical conflict in the contemporary world. Hence and given the positive points of environmental, economical and especially legislation in other legal systems such as European Union agreement regarding the energy charter in 1994 and since that study and analyze the energy issue and status not only environmental and economic point of view, but legally has also a special place, therefore the current paper focuses on the issue of energy sources & consumptions status in European Union law in order to provide legal pattern in Iranian legal system and comprehensive energy policies managed by European Union in the grounds of energy such as environmental protection, renewable energy applications, diversity of energy sources, using new technology  in reducing energy consumption, expand international cooperation and regional laws and regulations regarding energy and environmental protection.

Studying the environmental pollution resulting from tourism in plages and some strategies for reducing it (Case Study: Shahrdari Plage and Tooskasara Plage in Ramsar City)

Abstract—Beaches and plages have an important role in attracting tourists, because they have natural features. Tourism causes income generating, as well as environmental degradation in the region and types of pollution. Since these areas are not vast, in a short time, large amount of garbage and sewage will be produced there. We studied the conditions of Shahrdari plage and Tooskasara plage in Ramsar. The purpose of this research is to study the amount of produced garbage and sewage of tourists and their seasonal distribution in the most and least visited days and to compare the number of tourists and types of pollutions of the mentioned plages. Our methodology is cross-sectional and it is a library and field-based study. We went to the municipality of Ramsar for data collection. Since our study is field-based, we went to the plages to observe and measure the number of visitors and the amount of garbage and sewage in April, August and December. We put statistics on diagrams in excel. The results suggest, there is a lot of garbage and sewage in the most visited months because of many tourists, lack of proper environmental controls and their limited area and there is more garbage and sewage in Tooskasara plage due to its better facilities. Thus, using modern methods of pollution control, eco-tourism facilities and proper culture building will keep tourists and protect the environment of the region.

Effect of caffeine supplementation on performance and carcass characteristics of male broilers chicks

Abstract: Caffeine added to drinks and food as a stimulator drug, and causes HCL secretion in stomach, hypertension and dilated blood vessels. In this experiment 200 1-d-old broiler chicks were randomly assigned to 4 dietary treatments (5 pens/ treatment of 10 male broilers each) in a completely randomized design. First treat was a control and the next three dietary treatments were supplemented with caffeine: 2) 0.5%, 3) 1.00%, 4) 2.00%. Broiler starter, grower and finisher diets, based on corn and soybean meal, were formulated, pelleted, and fed ad libitum. All data were analyzed by the analysis of variance general linear models procedure of SAS/STAT software and when treatment means were significant (P < 0.05), Tukey’s multiple range tests was used to compare means. Before analysis, the univariate test was used to assess the normality of all data. Results show that with inclusion levels of caffeine, FI and DWG significantly decreased. Different levels of caffeine had no significant effects on FCR. Pancreases, neck and bursa relative weight and carcass percentage in 21 d and neck, gizzard and thymus weight in 42 d significantly increased with higher levels of caffeine. It was concluded that there was no significant difference in 0.5 and 1.00 % of caffeine and 2% caffeine cusses caffeinism in broiler chicks. 

Evaluation of pressure treatments on microorganisms

Abstract: Novel food processing technologies aim to provide safe, high quality foods with desirable nutritional and physico-chemical properties. One of those emerging processes which could serve as an alternative method for food preservation is the use of high hydrostatic pressure. This treatment permits the inactivation of microorganisms and enzymes at low temperatures, whilst valuable low molecular constituents, such as vitamins, colors and flavorings, remain largely unaffected. Hydrostatic high pressure technology is relatively new to food industry and is more and more considered as an alternative to traditional preservation methods like heat processing. Inactivation of bacteria, spores, and virus has been demonstrated.

Re-Construction Management on Urbanities based on spatial approaches

Abstract: In the case of developing countries, the pace of urbanization is rapid compared to their level of industrialization, resulting in irregular settlements. It has been pointed out that the phenomenon of “over-urbanization” occurs as the urban population swells more than the level of economic development can support. Thus, it is now recognized that poverty is an important driving factor in the growth of cities in developing countries. The types and severities of urban environmental problems differ depending on the development level of “hardware” (infrastructure such as mass transportation systems, water supply and sewerage systems, and waste treatment facilities) and “software” (such as legal systems and market economy mechanisms) for a given level of urban economic activity. With this over-urbanization phenomenon, urban environmental infrastructure is a cause of shortages, and poverty is an important factor preventing the formation of financial mechanisms that could facilitate urban environmental infrastructure improvements (Kidokoro 1998).

Nevertheless, since the 1980s, the economic growth of cities has been helped along by increases in foreign direct investment (FDI), as cities became connected to the global economy. Factors such as these are changing the patterns of urban growth. While such urban economic growth can be a factor that drives improvements in urban environmental infrastructure, it also encourages urban population growth. Moreover, this can intensify problems associated with both environment and environmental infrastructure. In following sub-sections, the issues related to urbanization, economic growth, environmental problems, and their inter-relationship are discussed.

Effect of caffeine supplementation on Immunity response of male broilers chicks

Abstract: Caffeine added to drinks and food as a stimulator drug, and causes HCL secretion in stomach, hypertension and dilated blood vessels. In this experiment 200 1-d-old broiler chicks were randomly assigned to 4 dietary treatments (5 pens/ treatment of 10 male broilers each) in a completely randomized design. First treat was a control and the next three dietary treatments were supplemented with caffeine: 2) 0.5%, 3) 1.00%, 4) 2.00%. Broiler starter, grower and finisher diets, based on corn and soybean meal, were formulated, pelleted, and fed ad libitum. To assess humeral immune response, evaluation of antibodies against sheep red blood cell (SRBC) on days 36 and 42 were used and to cellular immunity, Coetaneous Basophile Hypersensitivity (CBH) was used. All data were analyzed by the analysis of variance general linear models procedure of SAS/STAT software and when treatment means were significant (P < 0.05), Tukey’s multiple range tests was used to compare means. Before analysis, the univariate test was used to assess the normality of all data. Results show that caffeine supplementation significantly increased humeral immune response, and 0.5% caffeine induces maximum IgM in 42d. Although cell mediated immunity significantly decreased with inclusion level of caffeine in day 14, and maximum cellar immune response were shown with 0.5% caffeine supplementation. It was concluded that 0.5 caffeine supplementation cause maximum humeral and cell mediated immune response in 42 and 14d, respectively.

Designing Rule-Based & Decision Tree Spam Detection

Abstract: Amongst the security threats against the e-mails are the spams. To detect spams, the key word databank is selected and the specified keywords are saved in the relevant data structure. When an e-mail is received, its contents and behavior are reviewed. Since it is presumed that the nature of the e-mail content is that of text, in order to decrease the disparateness and increase the efficiency, the text is summarized, the roots of the words are determined and set on a vector and then the rule-based scoring of the vectors is applied. In addition to common rules, new rules are also introduced into this expert system to enhance its efficiency. On the contrary to common systems which apply the Naïve Bayes classification, the decision tree is used to develop the expert system. In the assessment done afterwards by means of a standard dataset including 21 properties and 4601 samples, we concluded that the F-measure attained by decision-tree classification is larger than the one by Naïve Bayes classification and therefore it provides higher accuracy. The other conclusion was that the resultant FPR from decision tree classification is smaller than the one from Naïve Bayes classification which means it has fewer cases of wrong detection. The precision relevant to decision tree classification is also higher than the precision provided by Naïve Bayes classification which proves a higher degree of accuracy in its algorithm. Through a comparison made between the results of the decision tree classification and sample-based learning method, we came to similar conclusions. A review of the cost, TN and FP factors also revealed that besides the assistance it provides to the experts in exploitation of data, the decision tree classification is an optimal method compared to the common Naïve Bayes (simple) classification.

Economic sustainable development through entrepreneurship and social capital

Abstract— Social capital is one of important organizational capabilities and assets that can help organizations to create and develop the human capital. Experimental evidences in knowledge-based societies clearly reveal the importance of knowledge creation process in relation to social capital in organizations. Social capital is a new concept that is posed in economic reviews in modern societies.  In the absence of social capital, other capitals lose their effectiveness and make it difficult to pave cultural and economic development path. Introduce this approach on many economic issues is representative importance of structures role and social relations on economic variables. This approach in economic discussions shows the importance of structures and social relations on economic variables. 

Social capital is essentially a collection of networks, norms and cognitions (understanding) that facilitates cooperation within groups and between groups in order to achieve mutual interests. Social capital is primarily based on cultural and social factors and identifying it as an investment in macro management level in developing countries and companies and firms can create a new understanding of social-economic systems and help managers in better guidance of systems. In fact, addressing this matter as a potential can have an effective role in economic progress and development of a country. Therefore, we have tried to present concepts and issues of social capital and entrepreneurship and its functional role in economic development; then we state the relationship between social capital and entrepreneurship by offering a pooled model.

More Need of Professional Ethics in Accounting and Auditing

Abstract: Changing of the environmental, social and cultural conditions in a society has led to the changes in the needs of the human population and this change itself has resulted in developments and more need of higher technology and capitals which can’t be afforded by one individual. So for business and technology development we need more people to invest, and people will invest in such companies only if they are sufficiently assured about their investment. Thus the number of ownerships in the company will increase and this has led to a gap between ownership and management. In such circumstances, and given the diversity of investment, most of the individuals are attempting to invest and buy shares of companies that do not have any working or financial knowledge. In such conditions, the potential and actual investors rely more on the data prepared by accountants and auditors to make such decisions. Thus, accounting and auditing have become an increasingly important field in societies with developing economics. One of the distinguishing features of the accounting and auditing profession compared to most of the fields is the acceptance of responsibility for the public. Hence, the society (both government and people) have some expectations of this profession and to assess the stewardship of management task, one should be able to trust the data prepared by the accountants and reports from auditors. Therefore, accountants and auditors in order to maintain their position in society not only must have professional qualifications but must have genuine integrity, honesty and integrity. So, maintenance of confidence in the community is one of the most valuable assets of this profession. The present review aims to address the subject theoretically.

The Effect of Individual Factors and Characteristics on the Organizational Structure of Cinema as a Medium

Abstract—Human beings are considered as the key and most sensitive elements of an organization. Most of the new organizational and management theories refer to such a sensitive factor. But it is certain that the humans are different innately. The individual differences in an organization and among the staff at different ranks of professional environments are the issue that has attracted the attention of the researchers of behavioral sciences. Although the staff and directors of organizations have similarities, they are different from each other from several points of view and these differences make management of human beings more difficult. The more the awareness of the directors of the variety of such differences and their principles is, the higher the possibility for them to be able to coordinate better the endeavors of the individuals under their supervision to achieve organizational goals and increase individual and occupational productivity will be. Therefore, considering the significance and position of individual differences and characteristics of the staff in organizations, this study tries to not only express the concepts of individual and characteristic differences and the origin of individual and characteristic differences of the staff and its effect on their organizational behavior, but also some of the specific characteristics that affect the organizational behavior. In this direction, by using questionnaires as instruments and paying attention to the individual characteristics of the staff, we studied in which organizational structures the employees are inclined to be active. The validity of the questionnaire was confirmed by using the ideas of the qualified scholars and the questionnaire's reliability was examined through using Cronbach's Alpha test standing at 0.759 level. The statistical sample was prepared by determining Cochran sample volume formula for 346 people. The results of the research over the statistical sample and use of the t-test showed that the employees prefer the organic structure of the organization to the mechanical and middle structures and that they find efficiency, incentive, enthusiasm and cooperation and more importantly satisfaction in organic structures higher than mechanical and middle structures. 

Expression of Resistive economy Factors and its fundamental Elements

Abstract: The culture of using foreign goods and need of manufacturing enterprises to components, spare parts, machineries and importing raw materials and non-protection of above enterprises and relying on the oil revenues and in other word the fragile structure of state economy caused the enemies to benefit from a lever in the name of oil and economic embargos for threatening our country and use the above factor for leading the country towards critical conditions and economic recession. The only solution for releasing from the above status is expressing and executing the resistive economy policy and economic campaign (jihad). The structure of state economy may be strengthened against the foreign invasion (adopted embargos) using expression of the said policy by the leader of Islamic Republic of Iran and analysis of key elements mentioned by him. Promoting the culture of domestic production and modifying the economic structures through payment of low-interest loans for renovation and expansion of production lines, downsizing the economic activities of government upon proper enforcement of principle 44 of constitutional law for strengthening and economic prosperity particularly protection of above companies after assignment, taking effort for correct and complete execution of five-year development plans of Islamic Republic of Iran for increasing the productivity, employment and changing the economic structures, attraction of dispersed and confused investments in production sector through modifying the interest of banking deposits and capital market (stock exchange), as well as attraction of foreign investments upon guaranteeing the return and productivity of investments made through holding the relative conferences and prevention of irregular import of consumables may provide the requirements for retrofitting the state economy.     

Evaluation Performance of the Banks in Attracting and Retaining Customers

Abstract: Increasingly need of people of banking services has caused that initiative plans and projects and fresh approaches are taken into consideration due to different reasons such as development of cities, unsafety of money transfer, acceleration in work procedure, necessity for balance control and payments on the one hand and necessity for realization of people’s expectations, customer loyalty and attraction of new customers.   Knowing and innovative, perseverant and updated administration is a necessity of administration structure of any bank. It seems that similarity in publicity by banks in television and radio media, the press, billboards across the city, media and granting awards do not create the required motivation among customers. Meanwhile, some of managers of banks assume that bank marketing administration has the duty of publicity and advertising. However, duty of marketing administration goes beyond what is assumed by the managers. Herein this paper, in order to survey the case, a hypothesis has been developed (Material motivation, compared to other intra-organizational elements plays the prominent role in qualitative and quantitative promotion of performance of bank personnel). In order to examine the case, a questionnaire has been used for this purpose. The statistical population includes nine state banks accordingly. 


ABSTRACT: Auditing profession has an important role in the world economic system. Auditors' impart credibility to the enterprises performance report and financial position with a reliable basis for decision making by stakeholders. Auditors critical role in the economic system, made the audit profession distinct from other professions and made it vulnerable and affected by numerous and complex economic events. Auditing profession in the world, already several times experienced the mistrust crisis and forced to pay substantial restructuring and finally, each time has been able to regain lost trust. In Iran,the auditing profession establishment is young and leaves early years of its life. Iran's economy is dominated by the state and private sectors and competing that is elements of a free economy and a major driver of economic transactions and decision making, doesn’t have share of striking. However, auditing profession has facing various challenges in Iran. In this paper ,we describe the auditing developments in Iran, challenges, current solutions for the problems and also the facing opportunities to this profession.  


ABSTRACT: The present study aims to assess the existing governmental accounting system in Iran and analyze its weaknesses. It also shows how accrual accounting can facilitate government policies. Recently, some evidence of increased awareness among government officials about the need for more fiscal discipline (economic discipline) can be noticed in the management of government agencies. Furthermore, it is generally accepted that the structure of public resources management and management procedures, including accounting systems used in the public sector, are not appropriate to implement the government plans with the more sufficient application of public resources. Compared with the public management sector in developed countries, accounting procedures, budgeting, financial reporting and auditing has had slight alterations in Iran during the last century. In the current study, first, we investigate the structure of governmental accounting in Iran and then, the existing obstacles are analyzed and some solutions are proposed.

Investigation the plant population and irrigation cycle base on growth characteristics on red beans in Arak climate condition (markazi province)

Abstract—:A study was carried out to evaluate plant population and irrigation cycle on growth characteristics of two red bean cultivars, in  Khomein National Research Station(markazi province ) in 2008-2009. The experiments were carried out with factorial design with three replications. Treatments were included irrigation cycle in two level( irrigation after 5mm and 100mm evaporation from pan ) as main factor and three population levels, respectively(30,40 and 50 plants per square meter with the  4, 5 and 6/6 cm space among the rows) and two red bean cultivars (Goli and Azna)  were considered as sub factors.

The results of variance analysis showed that drought stress  on the  characteristics such, plant height level occurred in probability level of (p<0.01) and in the rest of the characteristics were not statistically significant, also plant height and stem diameter the number of nodes on the main stem  and the number of sub branches in probability level(p<0.01) has been affected by cultivar, stem diameter and number of sub branches  in probability level (p<0/01) and the number of nodes on the main stem at the level of probability(p<0.05). However,the interaction effects of stresson various bean cultivars in this study has been set in.the  probability level (p<0.01), as well as all interactions between cultivars and population on the number of sub branches were  significant (p<0.01).  In this study theinteractive effects ofthree factorson the numberof branchesat the probability level (p<0.05) were been effective. 

Studying effect of physiological indexes of growth on irrigation management and planting pattern in two cultivars of red bean under Khomein climate conditions

Abstract—To evaluate the effects of planting density and irrigation management on the physiological characteristics of two cultivars of red beans (Goli and Ezna), an experiment was conducted in 2007-2008 crop year in Bean National Research Station in Khomein city. Experiment was conducted assplit –factorier plot design on  randomized complete blocks design with 3 replications. Treatments consisted of two levels of irrigations (irrigation after 50 and 100 mm evaporation from class A pan) as main factor and three density levels, respectively (30 , 40 and 50 plants per square meter with spacing 4 , 5 and 6/6 cm on row) and two cultivars of red beans were considered as sub factors. The results showed that drought stress of leaf area index parameters (LAI) has reduced crop growth rate (CGR), in the index of relative growth rate (RGR), firstly drought increased RGR and then receiving higher GDDs, decreased relative growth rate (RGR). Density increase from 30 to 50 plants per square meter increased leaf area index (LAI), crop growth rate (CGR) and relative growth rate (RGR).

Qualitative and quantitative characterization of municipal solid waste in Ilam

Abstract— Solid waste due to rapid population growth and urbanization in many cities over the past has raised concerns for officials. Disposal of Municipal waste in each area according to the type and quality of waste is different from other regions and usage of disposal method without any assessment of waste and local adjustment factors are outstanding action.  In order to characterize the quantity and quality of solid waste in Ilam, statistics and existing documents of municipal were used. To collect and complete this information and determine the physical and chemical analysis, per capita production and determination of physical components of waste was documented to standard library documentation.

The findings indicate that the average waste generated in the city is about 130 tons per day. The same amount increases 1.2 fold in summer in such a way that 77.2 percent are of the organic and degradable waste and about 4.8 of the total waste are paper and paperboard and 18% are recyclable materials such as plastics, metals, glass and etc. Also, all parameters of chemical waste in Ilam as compared with Iranian standard to produce compost have been standard.

Ilam produces about 130 tons of waste pre days, which make up more than 77 percent of the organic waste. At the present, it does not have compost production plant and any official or municipal organization does not try to recycle. Given that paddlers sporadically try to collect dry recycled waste unsystematically therefore it is necessary to provide necessary facilities for construction of the compost plant while organizing recycle situation.

Application of NIR spectroscopic analysis in detecting mechanical damage of agricultural products

Abstract— Mechanical damages in agricultural products appear due to impacts and compressions produced during harvesting, transport, and manipulation processes. These damages have a direct effect on loss of quality and reduce sale prices. Until now, the objective has been to describe the mechanism of damages and their prediction from widely used tests such as puncture tests or compression tests. Although these techniques give high quality information about damages, but they are destructive methods. So recently investigations have focused on the use of new technologies that are nondestructive and minimal time consumers. Near infrared spectroscopy (NIRS) is one of the these technologies that will help the food industry to provide better products for the consumer and reduce potential economic losses.

Analysis the effect of trees and fruit plants as urban green walls, on increasing sustainable natural resources

Abstract- According to increasing development and challenges of city lives, conserving the environment is essential more than before. Hence, sustainability and sustainable development arise to save urban habitats from industry and technology and to save and develop natural resources as a factor in planning agenda. Considering city parks, land occupation to greeneries and so on are considered in this approach. Although there are tensions here: green and open spaces do not lead to direct benefits so, there is a little financial support behind them. But there is strong willing to find new solutions about urban greeneries development in developed countries because of commitments over agreements and ecologic charters and also, public force. There for, one of the predicted solutions is taking benefit from urban green walls and roofs. Using these walls as modern urban development strategy to conserve city environment, decrease pollution and energy consumption optimizing is discussed. Besides having environmental benefits, they lead to sustainable aestheticy in urban landscape. This thesis, besides studying concepts like sustainability, sustainable development and green wall, analyze the role of urban green roofs and walls in city stabilization by analytic-descriptive method and library studies. In last, necessity of survey becomes clear and suggestions are presented. In general, studies show that paying attention to urban green walls, specially ignored spaces, has a significant effect on urban ecology and pollution decrease. Plants as natural filters, increase livability rate of cities.

Assessment of site and damage incurred in natural and planted stands of Haloxylon persicum in Abbas Abad region, Miami County (Semnan province)

Abstract— Haloxylon plants are leafless shrubs with an articulated stem that were planted to stabilize moving sands as well as to green desert but they became gradually wilted and declined. Few studies have been done on damage incurred and resistance of natural and planted stands of Haloxylon. The aims of this study are to identify pests of Haloxylon shrub and their effects on this species as well as to compare natural and planted stands of Haloxylon in Abbas-Abad region of Miami County. In each stand a 1ha plot was selected randomly and parameters including density, number of main branches, individual height, collar diameter, canopy area, seeding rate, regenerations, seed conditions, vitality, and amount of damage incurred by pests were measured and evaluated. To identify pests, regular visits were made throughout the year and live traps, dead traps and mesh-fabric traps were used to capture pests. Results showed that in natural stand density (307 individual per hectare) and canopy area (2965.27 m2 ha-1) were higher than planted stand. In planted stand, amount of seed production (79% of individuals), number of regenerations (1239 individual per hectare), percentage of healthy seeds (72.75%), and vitality (61%) were higher than natural stand. In natural stand 52% of individuals were completely infected by pest but for planted stand this value was 88% representing higher resistance of natural stand to pest compared to planted one. Pests Caillardia azurea Log., Acanthococcus abaii Danzig., Eriophyes sp, and Allactaya elater Lich., were identified, and the highest damage in both stands had caused by pest Caillardia azurea Log. 

The Identification of the Red Grape Bunch Using Image Processing and Neural Networking

Abstract— In this study a system of automatic processing based on color and color components is explained. About three hundred images have been taken from Urmia’s grape fields from early morning to evening in sunny and cloudy weathers.  Multilayer perceptron neural network with an after-error-publication learning algorithm was used as one of the tools of artificial intelligence for recognizing and separating different image classes. The input of the network was the average of the color components (R, G, and B) of the pixels of the images and the outputs of the network were [1] as the red grape bunch and [0] as a non-grape objects (i.e. leaves, sky, branches and trunk) which, finally, after trying and testing of the learning algorithm the number of neurons of the neural network was determined; using 13 neurons in the hidden layer and one hidden layer the learning algorithm of Trainlm with sigmoid function was able to recognize and separate picture classes with 98% precision. The results of the analysis of the pictures show a high precision in the separation and classification of classes of pictures. 

Strategies for urban green path sustainable development with the emphasize on conservation and enhancement of urban habitat

Abstract-Sustainable development is established to improve quality of life of citizens, habitat management and reaching to a better future. Planning for urban green path as public space is an effective strategy to gain sustainability. It meets basic human needs in urban spaces and is a combination of framework, spirit, aesthetic y and nature. It also helps improvement of urban identity. One aspect of sustainable green path is landscape as a set of natural and artificial factors which is important for designers because of being real, objective and the result of citizens perception of the city. This thesis is decided to ascertain green path development with the emphasize on urban landscape and sustainable public spaces. Since it has a basic role in joining natural and artificial environment, it is essential to come to strategies and principles as urban designing guide lines.

The role and importance of themajororgans on osmoregulation in fish 

Abstract_Among the most important settings that fish must be apply in the specific environments, is salt and water balance. There are a few species that their internal salt concentration is close to their surroundings. Cells to survive in an environment need the specific concentrations of certain substances, such as dissolved ions in the water. Indoor fish's body must have needed a set of ionized salts, alkalinity and dissolved organic compounds, while the external environment has a set of several of these factors. Thus the possibility of balance concentration of ions in the blood and keep it in a certain concentration, is need to transfer one side of membrane to another side with control mechanisms. Until provide unification concentration of ions in the blood with fish living environment water.Lose of ion and vital molecule such as water or inter certain ion in blood and tissue of fish or increased their concentration in blood can to be threat for continue of fish life. This paper is discussed the performance of various organs involved in osmoregulation of fish.

Half-Century Air Temperature Trends in Iran

Abstract—Global warming and climate change will have a significant impact on the sustainability of water supplies in the coming decades. Impacts of these changes can be observed in hydrologic time series. In this study annual mean air temperature of 30 synoptic stations of Iran in the period of 1961 to 2010 used to investigate possible trends. Spearman and Mann-Kendall non-parametric trend tests which are known as appropriate tools in detecting linear trends of a hydrological time series are adapted in this study. Results showed that there was no significant difference between Mann-Kendall and Spearman tests and Spearman test employed to trend analysis of all synoptic stations. This analysis indicated that 46.7 and 10 percents of stations detected significantly positive trend at 1 and 5% levels respectively.

Studying the role of Mycorrhizaas a biofertilizer in agricultural in agriculture

Abstract:Following the huge growth of world Population in recent years; The Production of agricultural crops in unavoidabl one of the strategies of high Production of agricultural crop is to increase the yield in area unit for mid-term or Long- term by using chemical and biological fertilizers. among the different fertilizers; The chemical fertilizers are more used because of Their suitable effectiveness and their more comfortable use, ignoring That their excess use leads to environmental Pollution and this problem is one of concerns of today huma To solve this problem; it seems necessary that suitable strategies are offerd to decrease the application of all kinds of chemical fertilizers; and consequently the envirnmental pollution the researchers believe thatby a good and correct management and by using bioligic fertilize and microorganism; we can Provide better nutritional conditions to Plants. Some of soil miccroorganisms are able to form a symbiotic relation to host through occupation of a part of plan,s roots. Among these; the fungus symbiosism to plant is one of the most importas phenomena in natural and agricultural ecosystems. mycorrhizafungs is able to form a symbiosysm to the roots of terristrial Plants. Then both of the can benefit and help each others life. The most of identified plants on earth plant can form the symbiotic relation. But It is variable depending on the root of host plant and morphologic proparties of symbiont fungus. The most intersting propert of mycorrhiza fungus is to increase the growth of host plant; and this symbiosis causes the quick exchange of nutritional elements between host plant and fungus. Then biofertilizer ofmycorrhiza can help us reach Sustainable agicul.

The role of biological control in sustainable agriculture

Abstract:Nowadays, in order to supply the food needs a growing population, increasing the performance of crops per unit area has been an impressive increase in performance to look for excessive use of chemical fertilizers and pesticides can be fitted, unaware of the possible consequences of the large intake of these chemicals to the environment and human looking, based on this in this article were it to try one of the methods of biological pest control, namely compilation control (bio-containment) evaluates. Biological control method with useful live agents against decisions harmful organism (pest) can be fitted in. By applying this method to control harmful organism, topically, or because it populations will be removed to a size-reduced its economic damage was not the nutritional and other pest is not considered.

The use of natural enemies of pests can be effective step in reducing environmental pollution, but it should be noted that this type of control will not be alone in destroy all pests. To get more effective results consolidated control that it is better to apply several methods used to control rather than a method.

Investigating the Impact of Groundwater Electrical Conductivity Changes on Desertification Trend Using GIS (Case Study: Mehran Plain)

Abstract— Desertification has been considered as one of the most destructive phenomena in nature and over the past few decades. There have been many international efforts to prevent and balance this phenomenon. Understanding the processes of desertification and factors involved in it and also awareness of the varying degrees of intensity of these processes and factors are important and necessary matters which have to be assessed and evaluated. Over-exploitation of groundwater degrades water quality. Using low quality water is one of the contributing factors in soil salinity and desertification increase. To evaluate the impact of electrical conductivity in desertification trend in the study area, 9 wells located in the Mehran plain were investigated over three time periods (2004-2008, 2001-2005, and 2009-2012). Iranian model (IMDPA) and ArcGIS9.3 software are utilized firstly to give weights to the information layers, then every layer’s value is interfered in the specified indicator and its effect on desertification was evaluated. Then, each layer was granted a weight between 1 and 4 according to the study area conditions. Finally, for each parameter and according to weights allocated, a map was prepared. The results showed that the intensity of desertification increased from the beginning to the end of the study period, so that, at the beginning of the period 8.95% of the area was classified at severe desertification class, while, this class increased to 14.47% at the end of study period.

Assessment of energy efficiency in agro-forestry systems of date palm and Barely (case study)

Abstract— The systems of Agro-Forestry lead to the increase of the resistance and efficiency of the resources use in agricultural production systems with the rise in biodiversity. Assessment of the energy efficiency of these systems has contributed to the energy challenges in the sector of the production of agricultural products and improves the energy productivity in these types of production systems. Hence 100 gardens of date which have the date and barley agroforestry selected randomly in the region of Sistan and Baluchestan and the data related to the input and barley pertinent to the agricultural year of 2011-2012 were obtained from the farmers in the form of the questionnaires. The results demonstrated that in the systems of agricultural forests of forage date and barely, the total energy inputs and outputs are respectively 34401.94 and 104671.28 MJ ha. Accordingly, the energy use efficiency was calculated 3.04 in this system that was about 0.9 units lower in comparison to the date monoculture system. This is due to the use of chemical fertilizers in the production of forage barley and the barley’s failure to reach to the stage of seed production. The results also revealed that in forage date and barley agroforestry, a cycle between human, livestock and plant is created while the rise in biodiversity and the farmers’ income. In addition to provide part of the required forage, it reduces the waste.

Fuzzy logic in intelligent agriculture 

Abstract— Fuzzy logic is an extension of Boolean logic dealing with the concept of partial truth. Whereas classical logic holds that everything can be expressed in binary terms (0 or 1, yes or no, black or white), fuzzy logic replaces Boolean truth-values with degrees of them. Fuzzy logic permits the use of linguistic values of variables and imprecise relationships for modeling system behavior and it is a powerful concept for handling non-linear, time-varying and adaptive systems. Due to need to improving agricultural systems and increasing the farmer's income, this paper presents an overview of fuzzy logic literature, modeling techniques, applications to agricultural systems; an example expresses the steps of constructing a fuzzy logic model and discusses the strategies for improving of agricultural systems.

Effect of different levels of salinity and nitrogen fertilizer on MDA accumulation and RWC content of two wheat cultivars at anthesis stage

Abstract — In order to study the effect of different levels of salinity (N) and nitrogen on some biochemical reactions of two wheat genotypes at anthesis stage, an experiment was performed under greenhouse conditions at the Agricultural, Medical and Industrial Research School of Karaj‎‎ in 2011.‎ Treatments were five levels of salt stress ‎‎(0, 6, 8, 10 and 12 dS/m), two nitrogen levels (50 and 150 Kg N/ha) and two wheat cultivars, Bam (resistant) and Tajan (susceptible to salt stress) arranged in randomized complete block design with three replication. Results indicated that under salinity stress condition, N application (150 kg N/ha) increased the RWC and also decreased the MDA content of both ‎genotypes. The positive effect of high nitrogen level on salt-tolerant genotype was more obvious than sensitive genotype. In conclusion genotypic differences between two cultivars, from viewpoint of tolerance to salinity stress and also fertilizer permeability between two genotypes caused that effect of augmentation of fertilizer utilization on Bam cultivar be more obvious than Tajan cultivar. These results demonstrate that nitrogen could be as a physiological solution to improve wheat tolerance against salinity harmful damages at anthesis stage.

Considering the effect of targeting the energy carrier subside on urban families’ food expenses in Kerman

Abstract— Targeting energy subside means removing subside on energy carrier price, which can both increase economic efficiency (optimized balance between supply and demand, increase in consumption efficiency and changing its pattern) and fair income distribution. For this, first, the consumption patterns of urban families in Kerman were considered, by using the Quadratic Almost Ideal Demand System and families’ income-expense data between “2002-2007” by income deciles. Then the income and price elasticity were examined. The mentioned groups includes: food, energy, clothes, transportation, communication and other goods. For all income deciles, as it was expected, the price elasticity is less than zero and the income elasticity is more than zero. Then the food support boundary of consumers was defined in 2007 and the effect of targeting energy subside on food support boundary was measured. The results showed that by increasing energy carriers’ price and cash payment of subside to consumers, the food support boundary of each citizen decrease from 211699 Rial to 165229 Rial. This project, generally, shows that before the implementation of subside targeting policy the first, second and third deciles and after the implementation of this policy the first and second deciles were enjoyed from food support.

Predicting surface runoff using a moisture- related runoff coefficient in the spatially distributed hydrological model, wetspa

Abstract— This paper explains how the WetSpa models calculate surface runoff. Since this method does the computation of runoff in an interesting rantional way, therefore the paper tries to give a detail explanation about it. A spatially distributed hydrologic model (WetSpa) is used to estimate daily/hourly runoff and river water discharge for each grid cell in the erea basin. The model combines topography, landuse and soil maps, and observed daily/ hourly meteorological time series to predict discharge hydrographs and the spatial distribution of hydrological parameters in the catchment. The discharge hydrograph at the outlet is composed of three components, i.e. surface runoff, interflow and groundwater flow. The model was applied on the Dinvar watershed in the Karkheh river basin of Kermanshah, with 72 months of meteo-hydrological measurements. In this study, a moisture-related runoff coefficient method is propose for calculating surface runoff in each grid cell, which allows the actual runoff coefficient to vary in time, and in function of rainfall intensity, rainfall duration and cell characteristics, giving an approximation to the surface runoff volume at each time step. The simulation results show that the model predicts the daily hydrographs with a good accuracy, 66% according to the Nash-Sutcliffe and the simulated total runoff volume is 48.01 that composed of surface runoff (2.4%), groundwater flow (21.28%), and Interflow (25.7%) and finally amount simulated total runoff(48.01) correspond measured total runoff  (48.07).

It is like most types of seafood full of calcium, iodine, and unsaturated acid protein. The meat of the aquatic creatures as a raw substance comprises a protein system that during fishing, transportation, preparation, and processing is exposed to a collection of internal changes and interactions resulting in its putrescence. Because of the nutritional and economic value of shrimp, this study investigated the effect of the different doses of green tea (200, 400, and 600 ppm) on the moisture content, pH value, peroxide value and the total volatile nitrogen and compared the results from various doses. The results indicated that the 600ppm dose had the most influence on the fall in the moisture content and the pH value while all doses of green tea significantly affected the other putrescent parameters (total volatile nitrogen and peroxide value, P<0.05). The results generally showed that different doses of green tea result in the increase in the qualitative parameters of shrimp during refrigeration.

Sowing Dates Effects, on Yield and Yield Components of Three Cotton Cultivars in North of khuzestan Province

Abstract— Sowing time is one of the most important factor for maximizing the yield Especially in those areas where temperature, day length, rainfall and humidity vary throughout the year The present studies were conducted to determine optimum planting date on three cotton varieties at agriculture research station-safiabad, Dezful, Khuzestan. The experiments were conducted in a randomized completely block design as split- plot with four replications cultivars. In all the treatments, cotton yield, fibers yield, seed yield and the percentage of lint were measured during the experiment. Analysis of variance for yield and yield components of cotton showed that the effect of planting date and cultivar on cotton yield and seed yield was significant but those interactions with each other were not significant. There was no significant difference among various planting dates in terms of lint percentage but the highest lint percentage in all three varieties was related to the second planting date with a mean of 33.9% while the first planting date had the minimum average with 31.7%. Among three cultivars studied the cyland cultivar had maximum yield loss with a decrease of 47 kg.ha-1cotton yield, 15.7 kg.ha-1 fibers yield and 31.2 kg.ha-1 seed yield. Termes 14 and cyland cultivars with 0.13% and 0.06% had the highest and lowest losses in lint percentage with 24-hour delay of the optimum time of sowing. According to all the result can be stated that early and late planting dates could lead to a decline in cotton yield and in aggregate the date of 5th April is the best planting date for all cultivars studied.

Comparing the efficiency of protein and maltodextrin on spray drying of honey: physical and functional properties, powder production yield

Abstract— In this study, the efficiency of Sodium caseinate (as a dairy model protein) and Maltodextrin was assessed on spray drying process of honey. The obtained results revealed that no powder will be produced in drying process of honey without using supplements, while using protein in spray drying process (as low as 10%), will increase the efficiency up to 50%. Comparing to that, reaching a similar efficiency will need large amount of Maltodextrin (up to 100% w/w based on dry weight of honey). The mechanism of action of proteins has been proven by other scientists using physical property tests, powder production efficiency and glass transition temperature (Tg). Recent study showed that preferential migration of protein to the surface of droplets/particles, which reduces adhesive behavior (stickiness) between particles and dryer wall by the increase in the surface protein coverage of the particles. The mechanism of Maltodextrin to decrease the stickiness is due to the increase in the overall Tg of the honey powders.

Calibration and validation results of the spatially distributed hydrological model, WetSpa, in the Dinvar Watershed, Karkheh, Iran

Abstract—The WetSpa model, working on a daily basis, is applied to simulate flow hydrograph for the Dinvar watershed. The Dinvar basin is located in Kermanshah, and the river is a tributary of the Karkheh River. The 6 years (2006-2012) measured daily precipitation, temperature, PET, and discharge data are used for model calibration and validation. The first 3 years (2006-2008) of the 6 year period is chosen for model calibration and the second 3 years (2008-2012) for model validation. The calibration process is performed manually for the global model parameters only, whereas the spatial model parameters are kept as they are. And For model validation, the calibrated global parameters are used to simulate the daily stream flow for the second part of the data. The results of a graphical comparison between observed and simulated daily flow at Dinvar , and evaluation criteria for the calibration and validation period show that the model performance is satisfactory for both calibration and validation periods.

Iranian Gazelles

Abstract: According to the conducted studies, three are species of gazelle in Iran, including Persian gazelle (Gazella subgutturosa), Jabir gazelle (Gazella bennetti) and Mountain Gazelle (Gazella gazelle). Persian gazelle or the goitered gazelle is the most abundant gazelle species in Iran; unfortunately, in 2008, it was added to the list of vulnerable and endangered animal species of IUCN. The species lives in 15 protected areas in Iran, among which Mouteh Wildlife Refuge is one of the largest populations of Persian gazelle depending on natural ecosystems. Examining the cytochrome b region in a number of conserved areas of the species showed that all of them belong to a pure population of Persian gazelle; however, the gazelles living in different habitats are significantly different from each other. Biometric studies on the skull indicated that the gazelles living in the Eastern and Western Zagros Mountains of Iran are distinct from each other. Persian gazelle mostly feeds on plants with high protein content. Indian or Jebeer gazelle is another species of gazelle living in Iran, which is considered as protected and endangered species in the country. Unfortunately, their species status has been so far controversial; thus, it has been not put on the IUCN list. However, there are strong morphological and molecular evidence suggesting that the animal belongs to the Gazella bennetti species. This species is very similar to the Persian gazelle, but smaller in body size. It should be noted that three subspecies of Jebeer gazelle have been identified in Iran. The Mountain gazelle is another species of Iran's gazelles, which shows more specification in the body color than other species. The only habitat of this species is in the Faroor Island in the Persian Gulf. The scientific name of the Iranian subspecies Mountain gazelle is G. gazelle dareshurii. In general, the three valuable species of Iran's gazelles are currently in need of need serious protection and support in order to prevent the extinction of such valuable biological resources and preserve them for future generations.

Rethinking the tools measuring species diversity: Application of multi-scale plots

Abstract— the measurement of biodiversity is essential for conservation, monitoring and management of vegetation. Given the importance of rapid assessment of species diversity, there is a necessity to use appropriate methods. However, current sampling methods may be complicated and confusing when the aim is rapid and accurate assessment of plant diversity, thus, using appropriate methods can lead us to the management objectives which are simplicity and speed, at the same the efficiency and accuracy. This paper reviews the sampling methods for measuring species diversity, especially multi-scale plots designed, and then, the necessity of application of suitable plots in order to measure species diversity. Moreover, it compares three multi scale plots including Modified Whitaker plot, Intensive Modified Whitaker plot, and C plot. As a result, to measure and evaluate species diversity due to increase in precision and accuracy, the application of smaller multi-scale plots in more repetitions would be preferred than large multi scale plots. Moreover, the C plot compared with the Intensive Modified Whitaker plot is preferred. It also draws a species-area curve by which can be compared different vegetation types. Finally, it is suggested that if the field application of other multi-scale plots could be applied, their advantages and disadvantages would be more carefully assessed.

Estimating Evaporation from Bare Saline Soils

Abstract—Iran is an arid country, its average rainfall is one third of world’s rainfall while it evaporates 3 times more than the world average. Evaporation takes place from vegetation cover, from bare soil, or from water bodies. In the absence of a vegetation cover, soil surface is exposed to atmosphere which increases the rate of evaporation. Evaporation of soil moisture will not only lead to water losses even it will also increase the risk of soil salinity. The risk is increased under low annual rainfall, saline irrigation water, and deep water table. Soil and water salinity is common in arid and semiarid regions where using saline water is common under insufficient fresh water resources. This research was conducted at Ferdowsi University of Mashhad, Iran. PVC pipes with a diameter of 110 mm, and an effective height of 1 m filled with loamy sand soil was used in this study as lysimeter for calculating evaporation rate. The results showed that salinity decreased evaporation and there was a chance for better prediction of evaporation at stages I and II.

Numerical Simulation of Underground Water Resources in Leilakh Plain of Kurdistan Province within the Low-Rain Years

Abstract— Kurdistan province is one of the major agricultural regions in the country in which Leilakh Plain is one of the active agricultural areas in the western part of country. In recent years, decrease in water rain and increasing growth of population within civil and rural regions, industrial workshop, spread-up of agricultural farms and discovery and exploitation of mines have led to increase in usage of underground water and huge decrease in static level of Leilakh plain. Due to the above-mentioned reasons, the future survival of rural and civil population is highly dependent on efficient method of underground water resources management in the plain. Therefore, development of a mathematical model of underground water resource management is the initial and most important action in efficient management of underground water resources. The objective of present survey is to develop a mathematical model of underground water currents in Leilakh plain of Kurdistan province. In order to attain this aim, through using Modflow computer code, a stable and non-stable numerical model of underground water currents was developed for Leilakh plain. Static-level data within observational shafts in 2007-2008 and 2008-2009 was used for evaluation and test of suggested models. In the follow-up, by using sensitivity analysis procedure, the effects of hydrodynamic features of underground water beds on prediction precision of mathematical models were examined. In fact, within the present study, the results of suggested models had a high match with observational data, so the suggested numerical model can be used as an effective tool for management of underground water resources in Leilakh plain.

Study the biological status of two species of  endangered turtles of Iran: Euphrates softshell turtle (Refetus euphraticus) and Hawksbill sea turtle (Eretmochelys imbricata)

Abstract: In general, there are 10 species of turtles in Iran five species of which are terrestrial turtles (non-marine turtles), and the other five species are considered sea turtles. The Euphrates soft shell turtle with the scientific name of Refetus euphraticus is the only soft-shell turtle in Iran. The back shell of these turtles is covered with a thick, soft and oval shape skin. It has a long and flexible neck with a roughly board head. The animal is distributed in Tigris and Euphrates (southern Turkey), northeastern Syria and Iraq. In Iran, these turtles are only seen in Khuzestan province in the basin of Karun River and Jarrahi River. According to the distribution of this species in hot and humid areas of Iran, and since the temperature in winter is not associated with a sharp decline in such areas, the turtles in province do not show the hibernation behavior. It is an omnivorous animal. Unfortunately, the Euphrates turtle is a critically endangered species facing extinction. In overall, habitat degradation, release of various pollutants into the habitat and fishing and hunting altogether have approached the species to extinction. The other species studied in this paper is the hawksbill sea turtle with scientific name of Eretmochelys imbricata, which is considered as a sea turtle. The animal is omnivorous in its early years of life, but after this period, it only feeds on sponges (only a few species of them). These animals are used to immigrate, and in some cases, the distance between their feeding areas and the location of their nesting accounts for hundreds, and sometimes thousands of kilometers. The hawksbill sea turtles nesting habitats in Iran include the coasts of the southern provinces of Bushehr, Hormozgan and Sistan & Baluchistan. In a study, the genetic diversity of this animal was examined in Persian Gulf islands using mitochondrial genome (mitochondrial D-loop region), and the results showed that the diversity of hawksbill sea turtles in Qeshm island is more than Kish island. In general, the haplotype diversity was calculated as 0.69, representing the low genetic diversity in this area. Therefore, the animal life-threatening factors by human interference are considered as the major factors for such a reduced genetic diversity. The results also showed that the Persian Gulf turtles have migrated to the region from Pacific Ocean and the Sea of Oman having a high genetic affinity with each other. Also, the hawksbill sea turtles hatching in the Persian Gulf weighted average and have a shorter length than the global average. They lay fewer eggs as well. The species, not only in Iran but throughout the world, is exposed to extinction, and thus, it has been registered in the Red List of International Organization for Conservation of Nature and Natural Resources (IUCN). Therefore, protection of these two species in order to prevent their extinction is as fundamental issues to be considered in our country, Iran.

NLP phytotoxin, a selective - biological herbicide of dicot weeds

Abstract— NLPs (Necrosis and ethylene inducing proteins) as microbial phytotoxins have been found in extensive range of microorganisms with different necrotic ability that cause hypersensitive immune response in dicotyledones weeds which result in extensive necrosis and death. This protein is not recognized by the immune system of monocot plants. NLPs have been used on dicot plants with various method like spraying, injection, hanging drop method and transferring its corresponding gene by Agrobacterium bacteria to the plant. Also a lot of auxiliary factors have been done such as the use of detergents, fungal or bacterial cell mid NLPs in order to increasing its effectiveness. The purpose of this paper is review of the target plants or host range of NLP, the range of microorganisms having this phytotoxine, how it works, ways to effectively use it as well as factors affecting its functionality as a biological herbicide.

The effect of polyvinyl polypyrrolidone, polyethylene glycol and urea on polyphenolic compounds and in vitro gas production of pomegranate seed and peel

Abstract— The objective of this study was to determine the effect treating pomegranate seed (PS) and peel (PP) whit polyvinyl polypyrrolidone (PVP), polyethylene glycol (PEG) and urea on their nutritive value, phenolic compounds and digestion coefficients. The PP and PS samples were sprayed with PEG, PVP and urea solutions and kept in airtight plastic containers for 3 days at room temperature. Samples were analysed for crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), ether extract (EE), ash, mineral content, total polyphenolic compounds (TP), total tannins (TT), condensed tannins (CT) and hydrolysable tannins (HT). The in vitro gas production method was used to estimate the DM fermentation parameters. The results showed treating PS and PP with urea led to a significant (P<0.05) reduction  TP, TT and HT contents. Treating of PS and PP with 10% PEG was probably associated with reduction (P<0.05) in TP and HT contents of PS and reduction (P<0.05) in CT content of PP sample. Inclusion of 10% PVP had no effect on TP and HT contents of PS and PP samples. Treating of PP with PEG and PVP at a level of 10% or treating with urea led to a significant (P<0.05) increasment in gas production compared to the control sample. The results suggest that urea solution was more effective in reduction of tannins in PP and PS samples, in comparison with PEG and PVP application. Spraying PP sample with urea or PEG and PVP reduced the tannin concentration, increased accumulative gas produced and improved organic matter digestibility, metabolizable energy and in vitro DM disappearance for PP sample. However more research are needed for better understanding the nutritional value of these by-products specially under in vivo conditions.

The Effect of Seed Age of Petropyrum Aucheri Seeds on its Germination Characteristics

Abstract— Petropyrum aucheri Jaubert & Spach is a native shrub of Polygonaceae family which grows in semiarid areas. One of the main problems in applied ecology programs in pastures is lack of access to full information about germination of a lot of native plants of pastures.  This lack of knowledge has resulted in some executive problems such as failure to recommend these species for planting in fertile areas and the use of non-native species.  Since no systematic study has been done on germination of petropyrum aucheri seeds, it seems necessary to investigate it. Some plants seeds have low germination percentage immediately after the harvest. One of the most important reasons of this phenomenon is plant physiological dormancy. This situation might change due to the seed storage in certain conditions or after some time during the seed lifetime. This research has investigated the effect of seed age on germination traits of petropyrum aucheri seeds. The experiment was carried out as a randomized complete block design in four replications. Three seed groups were prepared: 

A. Seeds which were almost one year old and had been in dry storage. 

B. Seeds which were separated from plant after maturation and were     sowed immediately after the harvest. 

C. Seeds which were harvested as immature and then were sowed. 

The results showed that germination percentage of the seeds which were in dry storage for one year had increased which was significantly different from immature seeds or the mature seeds which had just been harvested. It seem that  petropyrum aucheri seeds have a kind of physiological dormancy and need to be in dry storage in order to gain more percentage of germination. In fact petropyrum aucheri seeds have post-maturation stage. Seeds storage had no significant effect on germination rate in comparison to the state that the newly harvested seeds were used. Immature seeds had very low percentage and rate of germination and this matter rejects the intervention of the seed coat on germination. In other words, petropyrum aucheri seeds dormancy does not depend on their coat. It also seems that picking up immature petropyrum aucheri seeds prevents their post-maturation and highly decreases their germination percentage.

Abstract— Drought as a natural disaster incurs wide varieties of human casualties and ecosystem dames differed to others natural catastrophes like flood, storm and earthquake to some extent. The present paper aimed at assess efficiency of some common climate indices including standardized precipitation index (SPI), decile index (DI) and percent of normality index (PNI) in Hormozgan province (southern Iran) at four stations of Kahurestan, Brentin, Bandar Abas and Jask. The required diagrams were plotted in software's SPSS and Excel. According to the results of comparing minimum precipitation year to sever and extreme drought years suggested that PNI and DI showed too extremely drought simultaneously to minimum rainfall event and better efficiency than SPI index in terms of representing too extreme drought. Among stations of interest, SPI index does mot reflects precipitation losses in annual scale, however it forecasts drought and its periods rapidly compared to two other ones. So, the most suitable indoices to analysis drought condition during years of a given statistical period, those PNI ,DI were fall into the first place followed by SPI. Finally, it is recommended to prepare drought zonation maps to cope with drought in basins of interests.

Comparison of potato vegetative traits in aeroponic and solid culture systems 

Abstract—The solid culture cultivation is the common method for minituber production in Iran. This method has several disadvantages including low performance and high potential risk to pathogen infections. Aeroponic system is a new method, which does not require soil and has been successfully used for minituber production. Considering the fact that there is a positive correlation between growth and the performance of minituber production, evaluation and optimization of plant growth can significantly increase the efficiency of minituber production. This project was conducted at Seed and Plant Improvement Institute in Karaj in order to compare the impact of these two cultivation systems in growth characteristics of the Agria cultivar in 1391-1392. Two culture systems compared by t test in 36 replication. For growth evaluation, stem height, stem diameter, internode length, Dry matter content of stem and root, root length, stolon length, stolon diameter and number of stolons were recorded and analyzed. Results showed that except the dry matter content of both root and stem, other traits were significantly different (P ≥1%) with each other. Based on the results, aeroponic system had a significant impact on increasing the vegetative growth, so that the height of the stem with the average of 240.18 cm and root length with the average of 79.58 cm in aeroponic system were more than twice compared to the height of the stem and root length in the solid culture system. Stolon characters were highly correlated with mini-tuber production efficiency. In aeroponic system, the average number and the average length of stolons were 21.25 and 14.14, respectively, which were much higher than that of in solid culture system.

Revealed Comparative Advantages of Citrus Exports Among the Major Exporter  Countries : 1995-2010

Abstract— Based on the arguments in Balassa’s stages of comparative advantage thesis, this paper looks at the performance of exports in major produsers of Citrus over the period 1995-2010 and examines the RCA and the “Revealed Simmetric Comparative Advantage” (the RSCA) between these countries. The RSCA is also comparative to other measures of international trade specialisation. These measures included the Michaely Index, Trade Specialisation Index, Chi square measure and the Contribution to the Trade Balance.The results show that a number of countries such as Spain, South Africa, Greece, China, Egypt, Morocco, United States of  America, Netherlands, Turkey, Pakistan, Iran and Lebanon enjoyed the comparative advantage over the period 1995-2010. However Pakistan, Iran and Lebanon are losed their comparative advantage in the last years. Only countries of Spain, China, Morocco and South Africa their RCA index trends were upward and saw the most changes in 1995-2010. The results indicated that another countries’s Citrus export structure is faced with fluctuations and competitive position of their Citrus export has been weakened within the studied period.The evidence strongly suggests that despite the strong export performance experienced by another countries, thay are losing their comparative advantage with respect to primary years.

Investigating the Cultivation Method and Regeneration of Petropyrum Aucheri in Pots to Reclaim Arid and Semiarid Areas

Abstract— One native species of Iran rangelands is Petropyrum aucheri. Nowadays, the use of native species for rangeland rehabilitation is superior to imported species due to their more compatibility during the past years. Since there is not much information about cultivation of Petropyrum aucheri, and considering its importance, some experiments were conducted in planting tray and plastic pots in order to achieve ideas conditions for germination and establishment of Petropyrum aucheri. Several experiments were carried out in nursery conditions, greenhouse, and habitat of petropyrum aucheri. All of the experiments were observational and descriptive for determining the percentage of germination. With the failure of one experiment and low percentage of germination, other experiments were carried out and finally in the sixth experiment good results were obtained and the percentage of germination and survival of seeds was high and successful cultivation method and deployment of Petropyrum aucheri were achieved. The results showed that:

In order to propagate Petropyrum aucheri nurseries could not be used, because the seedlings of Petropyrum aucheri depend on light and need a lot of light during the day. In order to cultivate Petropyrum aucheri it is not appropriate to use planting tray, because it seems that the seeds do not receive adequate water and soil due to shallow depth of such trays. In addition, the poles of such trays are very open and they cannot hold water well; consequently, cultivating Petropyrum aucheri in plastic pots is more successful. Cultivating Petropyrum aucheri too deep fails, so it is better to plant seeds in shallow depth and about 0.5 cm. 

The young seedlings of Petropyrum aucheri need temperature fluctuations during the day and night at the beginning of growth and the seeds germinate better and establish successfully in such conditions. Therefore, cultivating the seeds of Petropyrum aucheri in greenhouse is not suitable due to lack of plant fluctuations.

The results indicate that the effect of different culture medium on quality index and number of leaves is significant at 1% level but on regeneration is not significant. MS medium with average (12.8 Leaves per explant) was the best medium for Roses explants in establishment stage. The highest quality of explants (4.5 Index), was related to the treatment of MS medium. We saw that this treatment showed significant difference with other treatments. The least quality of explants (2.56 Index), was observed in WPM medium. Characteristics which were studied in this experiment were consist of number of leaves, regeneration percentage and quality index.

Soil Quality for Sustainable Development

Abstract— Soil quality has found a very precious and special status in today’s agriculture and especially in sustainable development and neglecting it enters severe damages to the environment around us. Those measurable soil properties that affect the capacity of soil to empower product is called soil quality index. Some of the characteristics include organic matter, aggregates, pH, EC, nitrate nitrogen, and bulk density. The aggregated quality index or Nutritional Quality Index is two evaluation models in arid and semiarid regions. Soil stability index (SI) and the cumulative ranking (CR) are the other two models that are used to quantify soil quality based on its physical stability against erosion. Using these indicators of soil quality study is needed to solve the problems of soil. To fix any problem, the study of indices and soil characteristics is needed. Salinity, Sodium, and poorly draining are some of the soil problems that were examined to solve soil problems and its probable cause were examined.

Analyzing the role of women and providing guidelines for rural development

Abstract: Rural women in most societies constitute major force of agricultural work. Importance of women issue in Iran especially in rural areas on the one hand is faced with limitation of resources and manufacturing resources; and on the other hand with rapid population growth and mass of the jobless people, in achieving to rural development. Rural women work alongside men in all stages of agricultural crops and livestock production. In general, development is a multi-dimensional process with various economic, social, political and cultural aspects; and rural women's participation in this process has been an active and effective participation. Women in our country play a significant role in rural society Due to the unfavorable social, economic, cultural conditions and the extent of their participation in various economic, productive and services activities is in high level. The most important aspect of this participation has been its economic dimension for rural women. Many development economists believe that what ultimately determine the characteristics and trends of economic and social development is human resources of a country and not its capital and natural resources. As half of the human resources, women are not only the goal and purpose of any kind of development but also they are considered as a factor of the economic and social development. In this article it is tried to provide a comprehensive picture of the status of rural women as well as recommended strategies to promote rural life and women's role in and rural development.

Toxicity of some commonly used pesticides in tomato fields against Habrobracon hebetor (Hymenoptera: Braconidae) under laboratory conditions 

Abstract— Toxicity of some commonly used pesticides on different developmental stages of a biological control agent, Habrobracon hebetor (Say) (Hymenoptera: Braconidae), were investigated in the laboratory. Persistent toxicity of tested pesticides on the adult stage of parasitoid was also determined. The effects of pesticides on immature stages of parasitoid were tested by dipping H. hebetor larvae and pupae in pesticide solution at recommended concentrations. The adult wasps were exposed to field-recommended concentration of the pesticides on glass plates. Chlorpyrifos significantly reduced adult emergence when parasitoid larvae or pupae were treated with field-recommended concentration. Cypermethrin and iprodion+carbendazim also had a significant adverse effect on parasitoid emergence during the larval stage. Among all the tested pesticides, cypermethrin and chlorpyrifos exhibited the highest toxicity to adult wasps. Persistency test showed that chlorpyrifos and cypermethrin were “moderately persistent” and “slightly persistent”, respectively. Other pesticides were classified as “little persistent”.

Statistical downscaling of daily mean temperature in Shahrekord Station, Iran: an assessment of climate change impacts in a semi-arid region

Abstract—The increasing concentration of greenhouse gases (GHG) in the atmosphere due to human activities has resulted in global warming and a global energy imbalance. General Circulation Models (GCMs) are widely used tools to assess potential impacts of global climate warming. However, their outputs are difficult to use in regional impact studies because of their coarse spatial resolution. Downscaling techniques are used to bridge the spatial and temporal resolution gaps to reduce the problem of discordant scales by deriving regional climate information from global climate data. The objective of this study is assessing local climate change impacts on daily mean temperature using statistical downscaling technique. The application of statistical downscaling model (SDSM) is demonstrated with respect to the generation of daily mean temperature scenarios for Shahrekord station, Iran by 2010–2039. The data used for evaluation were large-scale atmospheric data encompassing daily NCEP/NCAR reanalysis data and the daily mean climate model results for A2 emission scenario of HadCM3 model. The results obtained from SDSM were acceptable for the temperature. From the downscaled results, it can be concluded that in the future, the station will become more “hotter” in the next 30 years using the HadCM3 scenarios. The maximum temperature rise of 24 ° C in July and the minimum in January with a value of 3 °C are observed.

Considering the effect of targeting the energy carrier subside on urban families’ food expenses in Kerman

Abstract— Targeting energy subside means removing subside on energy carrier price, which can both increase economic efficiency (optimized balance between supply and demand, increase in consumption efficiency and changing its pattern) and fair income distribution. For this, first, the consumption patterns of urban families in Kerman were considered, by using the Quadratic Almost Ideal Demand System and families’ income-expense data between “2002-2007” by income deciles. Then the income and price elasticity were examined. The mentioned groups includes: food, energy, clothes, transportation, communication and other goods. For all income deciles, as it was expected, the price elasticity is less than zero and the income elasticity is more than zero. Then the food support boundary of consumers was defined in 2007 and the effect of targeting energy subside on food support boundary was measured. The results showed that by increasing energy carriers’ price and cash payment of subside to consumers, the food support boundary of each citizen decrease from 211699 Rial to 165229 Rial. This project, generally, shows that before the implementation of subside targeting policy the first, second and third deciles and after the implementation of this policy the first and second deciles were enjoyed from food support.

An Analysis of Land Use Instability in Urban Settlements in Southwestern Tehran Metropolis

Abstract: Tehran metropolis, due to various factors such as concentration of capital, enjoyment of infrastructures and employment opportunities, has turned to the most important hub for attraction of population in Iran. On the other hand, factors such as implementation of some improper spatial policies in Tehran city and district and increase in land and property prices, low-income immigrants’ being pushed to suburban rural settlements and finally unsystematic physical expansion of such settlements all have led to the appearance of urban self-growing settlements around Tehran metropolis. Such local-spatial conditions are more prevalent in urban districts of southweastern Tehran which surround Saveh Road. Appearance of such districts was triggered by development of Islamshahr through spatial-functional annexation of rural settlements and change of agricultural lands and it was aggravated by farther structural expansion and emergence of new cities due to the increase in immigration to this district. Currently, this trend is still in full swing with the decreasing attraction of the original districts of these immigrants. 

With view of the role that these suburban districts play in the stability of settlement system of the wider districts and also having in mind the emphasis of other studies done in this regard on the social and cultural aspects of this issue, in the current study, employing statistical data and documentary and field studies, it is tried to yield a spatial analysis of instability of the land use pattern in urban districts around Saveh Road. Analysis of spatial-local distribution of land use indicates severe shortage and scantiness of per capita urban land use and this trend becomes even more severe in the cities which reach out to more suburban areas which are further away from Islamshahr. by considering these districts as an undeniable reality, Therefore, reforming and systematization of the current land use to initiate active and functional involvement of these settlements in stabilizing the zonal system and their residents’ enjoyment of better living conditions should be in order. By identifying and analyzing the roots and reasons of centralism in Tehran and reforming the land use systems, a sustainable spatial pattern for other condensed urban settlements in other similar geographical areas in developing countries becomes feasible.

In vitro effect of the adding of sodium hydroxide on rumen gas production of whole barley grain

Abstract— The purpose of this study was to examine the effect of treatment of whole barley grain (WBG) with sodium hydroxide (NaOH) on in vitro rumen gas production parameters. Experimental treatments included untreated whole barley grain (BControl) and treated barley grain with NaOH+water (35 g + 220 ml/kg DM WBG) for 30 days (BNaOH). In vitro gas production technique was used to determine the gas production parameters of the samples. The amount of produced gas at each time of incubation in each glass serum bottle was taken as the gas production parameter. Results of the in vitro technique revealed that alkali treatment of WBG caused an increase in the asymptotic gas volume (b) versus BControl (122.157 and 130.969 ml, respectively). Constant rate of gas production (c) significantly decreased by BNaOH compared with BControl (0.0247 and 0.0351 ml/h, respectively). Furthermore, treatment of WBG caused a significant increase in the halftime of maximal gas production (t1/2) versus BControl (28.05 and 19.74 h, respectively). The finding of the present study leads us to conclude that treatment of WBG with NaOH improved in vitro gas production parameters.

Experimental Study of the Effect of Guide Walls Asymmetry on Hydraulic Performance of Ogee Spillways with Curved Plans

Abstract—Executive limitations are among the factors that have attracted the attention of many hydraulic engineers. Designing an asymmetrical ogee spillway was the focus of attention of the present research. This study analyzed the physical model of a curved ogee spillway with a plan in the scale 1:50. The spillway was tested with both symmetrically and asymmetrically arranged guide walls while each state included 2 angles 60 and 90 degree angles. Hydraulic parameters were measured for 6 discharges per unit width in the range of 6.74 to 48.42 L/sec. Flow depth in   =4.92 with a symmetrical 90-degree angle was 3.47 times the flow depth in a 60-degree asymmetrical angle. Prior to submergence, the static pressure profile was reduced with an increase in the discharge passing the crown in all states and sample cross sections. However, the static pressure profile was increased from the beginning of the shoot. Therefore, the lowest pressure was reported to be   for a symmetrical 60-degree angle around the crown with 48.52 . However, for a symmetrical 90-degree angle with  , which experiences submergence sooner, pressure profile uniformly increased from crown to toe with discharges more than 40.52 . Accordingly, the peak pressure was reported to be    for the same angle with 48.52 . Based on the observations and diagrams it was concluded that symmetry or asymmetry did not affect static pressure. This finding was proved fora60-degree angle compared in the symmetrical and asymmetrical states. Moreover, the difference between the two states obtained for the 60-degree angle was caused by the influence of downstream flow on upstream flow, which was itself caused by the change in the flow regimes. Discharge coefficient was also independent of the effect of symmetry prior to submergence.

The effect of Green tea (Camellia Sinensis) on chemical change of white shrimp during refrigeration storage

Abstract— Shrimp a member of the aquatic crustacean species can be found in most parts of the world both in freshwater and saltwater form. It is like most types of seafood full of calcium, iodine, and unsaturated acid protein. The meat of the aquatic creatures as a raw substance comprises a protein system that during fishing, transportation, preparation, and processing is exposed to a collection of internal changes and interactions resulting in its putrescence. Because of the nutritional and economic value of shrimp, this study investigated the effect of the different doses of green tea (200, 400, and 600 ppm) on the moisture content, pH value, peroxide value and the total volatile nitrogen and compared the results from various doses. The results indicated that the 600ppm dose had the most influence on the fall in the moisture content and the pH value while all doses of green tea significantly affected the other putrescent parameters (total volatile nitrogen and peroxide value, P<0.05). The results generally showed that different doses of green tea result in the increase in the qualitative parameters of shrimp during refrigeration.

Biodiversity and Planted Forest Ecosystems

Abstract— Planted forests compare to natives are commonly very simple ecosystems in terms of their structure. These forests are subject to intensive management interventions to meet the efficient wood production which, in most established planted forests, is the explicit goal. The provision of ecosystem services and goods is related to ecosystem functioning. One of the important factors affecting ecosystem functioning is biodiversity. The biodiversity through two mechanisms including “niche complementarity” and “ecological insurance against disturbances and stress” affects ecosystem functioning. Lack of knowledge base that underpins the domestication and cultivation of tree well as the low uptake of mixed planted forests may be attributable to the fact that surprisingly little of the body of knowledge and ecological literature on the relationships between ecosystem functioning and biodiversity has transgressed into the silvicultural knowledge of planted forest management. But fortunately, there are promising signs that ecologists are increasingly studying on production ecosystems.

Each lightintensity treatment was replicated in 2 environmentally controlled rooms in each trial with 950 Ross × Ross 308 chicks per room. Data were analyzed as a randomized complete block design with trial serving as a block. All chicks were exposed to 40 lx of light intensity and 23 h of light for the first 7 d followed by treatment light intensity and 17 h of day length thereafter. Body weight and feed consumption were determined at 7, 14, and 35 d of age. At the end of each trial, 60 birds per treatment were processed to determine the detailed meat yield. Skeletal and footpad and ocular health were monitored at 31 and 32 d of age, respectively. Body weight, feed consumption, feed:gain ratio, and mortality were unaffected by light intensity. Carcass, thigh, and drum yield as a percentage of live weight decreased linearly with increasinglight intensity. The 1 lx treatment resulted in heavier wings as a percentage of live weight. Light intensity had no effect on skeletal health, but ulcerative footpad lesions decreased linearly with increasing light intensity. Birds exposed to the 1 lx treatment had heavier and larger eyes. In conclusion,light intensity did not affect broiler production and mortality but did affect carcass characteristics.

Soil methane emission from Afforested areas with Pinus eldarica and Robinia pseudoacacia in Cheetgar Park, Iran

Abstract—The increase in the concentration of the major greenhouse gases (GHG’s) in the atmosphere is considered one of the main factors causing the warming .Forest ecosystems are normally net sinks for atmospheric CH4, because rates of CH4 consumption exceed its production. Tree influences both the production and oxidation of CH4, and can play an important role in determining whether a particular forest is a net source or sink of CH4. Purpose of this study was to gain insight into the influence of plants species on the CH4 emission of soil. To achieve this, areas with Pinus eldarica and Robinia pseudoacacia plantation were selected in Chitgar forest Park. Soil sampling was done randomly. Some important soil properties such as pH,   CH4 soil emission, organic matter percentage, and  the amount of active carbon were measured. Gas samples were collected by a common methodology based on a static chamber technique for CH4. The results showed that species type significantly affects soil CH4 emission and CH4 emission was significantly higher for the soil with Pinus eldarica plantation. Considering the effects of Robinia on soil characteristics and methane emissions, it is supposed that this species can alter the soil into the reservoir of methane.

Hydrogeochemical factors governing the origin and transport of Cr from ophiolitic complex to water resources in the Pangi area (Kadkan, NW Torbat Hydarieh, Iran)

Abstract—The hydrochemistry of the water resources in Pangi area (Kadkan, NW Torbat Hydarieh), has revealed high concentrations of Cr and heavy metals (Cd, Ni, As) exceeding maximum permissible limit. The result of measurement by GFAAS showed that the highest Cr concentrations were found in waters in the vicinity of chromite mines. The high levels of Mg2+, Na+, Cl-, SO42-, HCO3- and Cr in the stream sediments often exceed the thresholds of the WHO standards. The water samples of the study area display pH with a mean 8.5, TDS with a mean of 1259 mg/l and EC showed 1978 μs/cm. Hydrochemical facies using Piper trilinear plot delineated two water samples as Na-Cl facies with Ca-SO4, Mg-Cl, Na-HCO3 and Mg-HCO3 facies as minor types. Local ophiolitic rocks, especially serpentinites and ultramafic units, are Cr-rich and represent a Cr source for groundwaters. Hydrogeological investigations confirmed high total Cr contents in soils and waters related to ultramafic rocks from northern ophiolitic zone. Cr(III) concentrations in resulting soils and sediments are magnified by weathering reactions, as a consequence of selective alteration of silicate minerals relative to chromite. The high concentrations of Cl-, Mg2+, Ca2+ and HCO3- well as high values of EC, pH and TDS in studied samples are related to weathering reactions of ferromagnesian rocks of ophiolitic complex. The abundance of Mn and Fe oxy-hydroxide (as electron acceptor) with Cr rich spinels in the study area, creates a chemical systems potentially able to increase the Cr(III) to Cr(VI) oxidation. Cr(III) is highly concentrated in areas where the dissolved oxygen content of less than 1 mg/l and pH is in the neutral range. The rate and amount of Cr(VI) in environment increases with increasing chromium concentrations and decreasing pH. As in the ophiolitic zone, pH is greater than neutral range (pH> 7.9) and DO>7.67 mg/l, Therefore, given the values of DO, Eh and alkaline pH of the water sample in the area, chromium in water resources area must contain significant amounts of Cr(VI) and is in the form of chromate (CrO42-). The hydrochemical data demonstrate that serpentinites and serpentine soils are main potential source of non-anthropogenic Cr(VI).The enrichment and variability of Cr in serpentinites and serpentine soils is directly related to the abundance and weathering of multicomponent spinel system.

Solutions for Tunneling Problems

Abstract— Tunneling through weak and jointed rock masses such as in the metro project of  Isfahan (Shemshak formation) is a challenging task for the planners, designers, engineers and the geologists because of high overburden, thickly vegetated surface, poor rocks and highly varying geology with the presence of numerous small and big shear zones, thrusts, faults, etc. Due to these reasons, tunneling problems such as squeezing ground condition, chimney formation, face collapse, water in rush, etc. have been faced in the past and are still being encountered. Failures and the problems may be regarded as challenges and opportunities for generating new knowledge base and thereby increasing self-reliance in tunneling. Accordingly, recent experience of (i) tunneling through the poor rocks experiencing the squeezing conditions, (ii) SRF rating in case of competent moderately jointed rock experiencing spalling and rock burst condition, (iii) tunnels under dynamic condition, (iv) the effect of rock type on bolt length and (v) the improvement in rock mass quality Q because of the grouting of full-column rock bolt grout are presented in the paper. The challenges of cost-effective grouting in water charged rocks and swelling ground and TBM tunneling in metro project of Isfahan (Shemshak formation) are also briefly highlighted.

Reducing Energy Waste Using New Materials and Modern Building Techniques in Buildings

Abstract: According to statistics issued in Iran, more than one third (1/3) of energy consumption is associated to buildings section. Among these, heating and cooling are the most important energy consumption factors in a way that about 70% of natural gas is consumed for heating in buildings. One of the most important factors that leads to thermal energy waste in buildings are walls. In fact, a considerable portion of building elements that works as a separator between inside and outside of the building is the wall that in the case of proper use of good materials like 3D panels you can improve their heat resistance to a considerable degree and hence prevent from energy waste[3].

In this paper, the impact of using new materials on energy consumption is to be known and we see that after that the whole building’s energy consumption is reduced. This has a considerable effect on fuel consumption and can compensate the building’s financial burden in a short period of time. Not only it is economically justifiable, but also it is beneficial.

Synthesis of carbon coatings on anodized aluminum alloys, and it's application as BTX pollutants adsorbent

Abstract— Industrial, agricultural and urban wastewater and sewage containing toxic organic substances are the major pollutants of surface water and groundwater. In recent years the use of adsorbents as an efficient method has got a great attention due to capability of this method in removal of the mentioned pollutants. In this work, the 7075 and 5083 aluminum alloys samples with the desired size and dimension were anodized in the oxalic acid electrolyte after heat treatment using a two-step anodizing. The above technique is applied because of more uniform honeycomb structure of oxide layer produced by this method. Then, phenolic resins and polyvinyl alcohol as carbon precursor were coated on anodized aluminum by simply immersion in the above polymer solutions. Finally, the carbonization process was carried out in a vacuum furnace for application of these samples as adsorbent. In this study, aqueous solutions containing benzene, toluene and xylene was evaluated as an indicator of organic pollutants. Results showed that the benzene, toluene and xylene content of aqueous solution have been reduced in all tested samples.

The Calculation and Study of the Radon Decay Chain in the Environment

Abstract— The main part of human exposure to radiation comes from the environmental radiation of Radon. It is estimated that half of the effective dose humans receive comes from radon and radon daughters with a short half-life. Radon is a colorless, odorless, tasteless and neutral gas which is 100 times deadlier than CO poisoning and is the second major cause of lung cancer after smoking. This study tries to calculate and examine the radon isotope decay chain which is hazardous in the nature. The results show that only five of the several isotopes produced in the radon-222 (222Rn) decay chain and whose decay in enclosed places reaches equilibrium over time are important. Studying those isotopes in dosimetry calculations is considered to be important while the other isotopes do not threaten our health.

Abstract— With the increase of environment pollution by heavy metals in the past decades and its effects on the food chain, phytoremediation can be a way to reduce pollution of metals from the environment. This study aiming to evaluate the ability of sunflower inoculated with Glomus mosseae for grow and uptake of lead (Pb) in a soil contaminated with zero, 600, 1200 and 1800 mg kg-1 Pb. This study was carried out in a greenhouse cultivation. Increasing lead contamination decreased root and shoot biomasses of sunflower significantly. In contrast, inoculation with mycorrhizal fungi, Glomus mosseae, increased plant growth in soil contaminated with lead. Percentage of root colonization by Glomus mosseae was rose by increasing the level of Pb to 1200 mg kg-1 and was reduced at 1800 mg kg-1 Pb. Lead concentration in mycorrhizal sunflower varied in the shoot biomass from 26.67 to 166.67 mg kg-1 and in the root biomass from 45.14 to 435.43 mg kg-1 Pb (for zero to 1800 mg kg-1 Pb respectively). Dry weight was varied and increased significantly above the permissible limit (30 mg kg-1 Pb), by increasing the lead level.

The Effect of Heat and Mass Transfer Coefficients on the Vacuum Drying of Porous Body, A Numerical Study 

Abstract— In the present study the phenomenon of drying a wet substance under vacuum has been investigated numerically. At first, the environment air pressure of the sample was reduced linearly in 1 min and then became constant. In this study the effect of heat and mass transfer coefficients on the temperature and moisture rate has been considered and the temperature and moisture rate distributions in the square-shaped substance due to the reduction of vacuum chamber pressure are predicted by numerical method. It is shown that for a high heat transfer coefficient, the center temperature of the apple gets to the balanced temperature rapidly, because much more heat is transferred from the fluid to the surface, while in similar conditions, no significant change in the moisture rate is observed. While changing the mass transfer coefficient has no effect on the temperature distribution, but the sample moisture rate is changed under the same conditions.

Management of Air Pollution Control in Cement Industry

Abstract— The cement industry is one of the oldest and most important industries in Iran’s economy as well as one of its greatest environmental polluters. Any activities that involve the breaking, crushing, drilling and grinding of materials may produce fine silica dust. However, the dusts can also be found in soil, mortar, plaster, shingles and abrasives. Dust particles are usually in the size range from about 1 to 100 µm in diameter. Pollutants are greatest risks for the environment and human health problems. The pollutants are often lumped together under the term smog. Dust generated in the cement industry can be studied in order to achieve the dust emission control equipment. Although many operations generate dust are inevitable, but the loss of trapping dust and prevent dust dispersion produced by techniques such as those outlined in the paper will be obtainable.

Evaluation Methods of Acidic Drainage due to Mining of Sulfide Minerals “Case Studies of Darrehzar Copper Mine”

Abstract—Environment is exposed to serious threats at global and national levels and it has forced all countries to organize and systematize the existing chaos by research and investigation about environmental problems. Acid mine drainage may be the worst environmental problem which has a negative and deleterious effect on the quality of surface and ground waters. Many of pollutions (especially in mining areas) refer to weathering and decomposition of rocks, minerals and mining pulps; these pollutants enter the life cycle of animals and plants by entering the geochemical and biogeochemical cycles (water, air, plant, soil, sediments, minerals, rocks, etc.) which leads to ripples and environmental problems. 

   Acidic drainage is obtained from the oxidation of sulfide minerals especially when pyrite is exposed to air and water. Iran has abundant mineral reserves and resources that their mining and processing can lead to a serious source of pollutants.

Among these, sulfide mines are important in extraction process due to aggravating the acidic drainages and increasing the concentration of heavy elements; it is also important in processing stage due to the emission of pollutant gases especially SO2. In this paper, we have investigated the geochemical processes and environmental issues of acidic drainages resulting from sulfide ores of copper mine in Darrehzar, Kerman. In order to rectify this situation, we can use the methods of “open limestone channels” to control and treat the acid drainage of copper mine in Darrehzar based on standard methods of managing the acid drainage and considering the situation of similar mines. Effectiveness of semi-industrial bioleaching project is recommended by performing various experiments.

Hydrological and geochemical processes controlling the origin and transport of Arsenic in the Pangi area (NW Torbat Hydarieh, Iran)

Abstract—In this study, arsenic concentration and pollution in water resources of Pangi area (Kadkan, NW Torbat Hydarieh), adjacent to Sarhang- Golbou ophiolitic zone, is investigated. Results of this study indicate high concentrations of arsenic in local water resources as arsenic concentration is 12 times greater than standard values in Golbou. Aquifer lithology, hydrological gradient, and water geochemistry of Roudeshour and adjacent areas show that the same processes control arsenic concentrations in surficial and ground water resources. As-bearing sulfide minerals especially pyrite and arsenopyrite are the main origin of arsenic in water resources. In spite of that, arsenic remaining time and mechanism of diffusion in water phase is controversial. According to geochemical studies, arsenic can be released at and close to surface of aquifer and then during geochemical reactions it can be transferred to depth. States of arsenic diffusion in aqueous phases depend on oxidation of As-bearing solid materials and displacement of antagonistic ligands. In presence of sulfides and reducing conditions, thioarsenic is dominant form of arsenic but in oxidizing conditions arsenate is dominant form. Thus, solution of Fe oxy-hydroxides together with arsenic diffusion, is the main agent of high concentration of arsenic in local water resources.

Compatibility Study and Comparison of Ten Soybean Cultivars in the Climatic Conditions of Iranshahr

Abstract— Soybean is an important oil crop because it contains 18-20 percent oil and about 40 percent protein. Since around 90 percent of the vegetable oil needs of the country are imported, evaluation of different soybean cultivars for planting them in various regions can play a considerable role in increasing oil crop production. For this purpose, 10 soybean cultivars were compared in the form of randomized complete block design in three replications at the Agriculture Research Station of Iranshahr in 2012. Results obtained showed there were significant differences among the cultivars with respect to the characters of seed yield, biological yield, and harvest index, number of pods per plant, number of seeds per pod, 1000-seed weight, and number of lateral shoots, plant height, and percentage oil content. Comparison of the means using Duncan’s method indicated that the maximum seed yields with 3487, 2803, and 2461 kilograms per hectare belonged to the cultivars Villiams, SAHAR, and Katoul, respectively, and the minimum to the cultivars L44, and M9 with 1243 and 1400 kilograms per hectare, respectively. Moreover, results of correlation analysis revealed that there were positive and significant correlations between the yields of the cultivars and the characters of biological yield, harvest index, number of pods per plant, 1000-seed weight, and plant height, and a negative and strong correlation between the yields of the cultivars and their percentage oil contents.

Aras river water improvement and application of phytoremediation for removal of industrial waste

Abstract— Today the pollution of the boarder waters has made crucial problems for the neighbouring countries.  Throwing the industrial and homemade wastes and water wastes, hospital and domestic wastes in to the water are examples of sources which make the water polluted and also making water warm is another problem arose from those activities. The pollutions which have been made by countries beside the basin of the river are one of the important struggles associated with Aras River. Recently mining activities in the suburbs and basin of the Aras river have increased the pollution of the waters going to the Aras and consequently the Aras river itself.  Mining activities and extraction of ore and metals in Azerbaijan, Armenia and Iran are examples of such activities. The entrance of pollutants to water ecosystems threatens both the natural environment and the health of the residents of that polluted region. The pollutants which enter through mining activities to the water penetrate to the Aquifer and soil and threaten the life of the residents. Underestimating the dangers of these pollutants not only threatens the life of local people but also the major part of the society. So these problems should not be underestimated. It should be mentioned that the water of Aras river is used in irrigation of agricultural fields in downstream of the East Azerbaijan and Moghan plain in the Ardabil province.  The results of this research show that in order to use wastewater in ponds, it is better to use plants which absorb metals. In order to reduce the effects of heavy metals tamarix shrubs and  Loui straws can be helpful to filter the water waste. The implementation of the new methods of filtering by considering the environment helps to reach the goal of filtering and also to keep environment itself.

A review of the biological status of Persian fallow deer (Dama mesopotamica), a precious and endangered animal species in Iran 

Abstract: The Persian fallow deer with the scientific name of Dama mesopotamica, is one of the two deer species in the world. The other species is the European fallow deer. The Persian fallow deer is the largest species of fallow deer and larger than the European species, but its antlers are not as wide and large as the European one. They are 60–100 kg in weight and 130–240 cm long with a 16-19 cm tail. The length of gestation in female is approximately 230 days. Their maximum life span is about 20 years and the maximum breeding age is around 15 years old. The maturity age in fallow deer is about 16 months, except that males are in fertile for several years. Persian fallow deer is usually nocturnal and rests during the day. The animal usually feeds in the early morning or evening. It has a very strong visual sense and is a very good swimmer. Molecular study of the animal has shown that there has no genetic mixing and hybridization between Persian fallow deer with deer transferred from Germany, and their population is absolutely pure Iranian with their own homogeneity structure. According to the latest statistics in recent years, there are about 551 heads of deer today in Iran that regrettably the number reduces everyday. One area of Persian fallow deer distribution in Iran in the Ashk Island is located in the National Park of Urmia Lake. Unfortunately, in recent years, the increased environmental crisis due to drought of Urmia Lake has led to intolerable environmental conditions of the area for the deer, and thus the reduction of their population. Fallow deer population experiences non- desirable conditions in their other breeding areas; for example, during the ongoing year (2013), the loss and death of more than 70 heads of Persian fallow deer in the Karkheh margins has exposed this valuable species to the border of extinction. Preserving the valuable genetic resources of this valuable species through generating fibroblastic germ cells as well as developing proper opportunities for increasing the number of deer followed by restoration and revival of Urmia Lake and making the environment conditions of Ashk island more viable for the Persian follow deer can be considered as necessary measures to prevent the extinction of this species.

Natural Fiber Reinforced Polymer Composite in Synthetic Bone Grafting – A New Approach

Abstract — Bio material is the term usually applied to living or processed tissues or to materials used to reproduce the function of living tissue in conjunction with them. Simply it is a material intended to interact with the biological system. Although autogenous- and allogeneic- bone grafts have been used for a long time in bone therapies, there is still a donor shortage and infection risk. As an alternative, synthetic biomaterials have been developed and clinically used as bone grafts. Disclosed herein are an environmentally friendly Biocomposite prepared from a mixture, as reinforcement, of fibers extracted from plant herbs like banana, roselle and sisal which have a medicinal value. Metals and alloys that are successful as bio materials include: gold, tantalum, stainless steel, Co-Cr, NiTi (shape memory alloy), Ti, Zirconia.  The selection of the material for implants depends on the complication of bone defects. Shortcomings of many metals include low biocompatibility, corrosion, too high stiffness compared to tissues, high density, and release of metal ions which may cause allergic tissue reactions. Polymer composites provide alternative choice to overcome the shortcomings mentioned above. This paper is intended to fabricate Natural fiber reinforced composite as a plate material by using the polymer bioepoxy resin (epichlorohydrin). The plate material uses calcium phosphate, calcium sulphate, hen eggshell powdered material and Hydroxy Apatite ceramic composite and collagen as its coating.

Improvement of heavy metal adsorption by nano-structured bentonite

Abstract— In this study because of the proper cationic exchange capacity, high specific surface, stability, and cheapness of clay nano-Bentonite, it was used as an absorbent agent for adsorption of zinc as a heavy metal. In order to improve the adsorption mechanism in nano- Bentonite structure a model was introduced based on three improving factors including: 1- dimensional factor and analysis of d-spacing effect 2- Inter layer cation types by investigation of swelling index factor effect 3- Effect of environmental conditions such as pH, metal ion concentration, absorbent concentration and stirring speed. For investigation of model efficacy, three mentioned factor were tested in three steps. First, preparation procedure was done on six samples for determination of dimensional factor amounts, d-spacing and swelling index. Then the expected sample for maximum adsorption based on these amounts was selected. Second, by using Experimental Design software and CCD design model, the environmental effect was investigated and optimum amounts were determined. Third, these conditions were tested for all six samples. Results showed that the decreasing of dimensions results in decreasing of d-spacing in samples and increasing of swelling index in Na-Bentonite samples. In Bentonite samples the counter effect of swelling index on d-spacing caused 30% increasing in absorption. Finally, a sample with dimension of 2.05 nm, swelling index of 17.6, d-spacing of 12.59 and absorption recovery of about 94% was selected as the best absorbent.These instructions give you guidelines for preparing papers for conferences or journals.

Numerical Investigation of the Performance of Ab-anbars with Windcatcher by using Computational Fluid Dynamic at Different Velocities

Abstract— One of the most important parts of traditional architectural structural building in Iran that have a significant impact on the urban landscape and architecture, are domes. In the natural architecture of the central plateau region, establishing a spiritual and material relationship between the environmental conditions and the use of arched ceilings, such as domes over the centuries has become an important feature of the place. In this paper, as an example of the masterpieces of the ancient Persians, the efficacy of such ceilings in ab-anbar with windcatcher has been investigated. The ab-anbar as one of the infrastructures has a great position in the Iranian civilization and is spread almost in the frontline across Iran. Ab-anbar space does not disclose and all of them have a vent for air. Confined space makes the possibility of access to storage inside difficult, additionally, it makes the water very hot, so on sunny days the storage inside is very hot. Therefore, all the ab-anbar has air vents on the storage roof. The vent and the windmill cause the coolness and the salubrity of the water in addition to the ventilation inside the tank. In this paper, we firstly discuss the function of the ab-anbars and then we study the function of ab-anbar with windcatcher under different velocities using computational fluid dynamics. For this purpose, first the geometric modeling and mesh structure is done in software GAMBIT and then we investigate the flow patterns in this type of ab-anbars with using FLUENT software.

Laboratory investigation of the effect of a new labyrinth with different length and width in the wing length of a triangular-shaped labyrinth weir

Abstract - Due to minor changes in the static load on the crest in case of large fluctuations in flow rate, polyhedral weirs, compared with other types of weirs, are considered as economic structures to control water levels in the irrigation networks. Using labyrinth weirs is an effective and economical approach to improve the efficiency of the weir by increasing its effective crest length. In this case, for a constant hydraulic height and width, it passes a greater discharge in comparison with other types of weirs. In this study, the V-shaped plan-form weirs are studied [1, 2]. Tests are conducted on 30 models with 7 different discharges, and in a total of 210 tests. The models include 30 V-shaped weirs with various lengths. The models are investigated in a flume with 8 m length, 0.35 m width and height of 0.40 m. The results of this study indicate that for all triangular-shaped weirs the ratio of discharge coefficient to P/  ( : total hydraulic load, P: weir height) is at first increased and after reaching a maximum, begins to be reduced. As the height of labyrinth on the weir wings increases, as a result of increases in effective length, the discharge coefficient is increased for a specific  /P. The results also show that increasing the wing length reduces the discharge coefficient. Also, the discharge coefficient is greater for V-shaped weirs than linear ones.

Survey Effective Factors on Adoption of Low Input Sustainable Agriculture from the Standpoint of Agriculture Experts in Ilam Province

Abstract— Nowadays the world is facing many problems, which the most important one of them is the Explosion of Population. This increase in population will cause serious implications on the consumption and distribution of food around the world. Previously, in order to meet the increasing demand for food, breeding livestock and further harvesting from agricultural land while enriching them with more nutrients, were the two dominant ways of increasing the production. But it seems highly unlikely that we can harvest more food by adding more nutrients to agricultural lands in the future. Therefore, designing systems that can comply with the long-term requirements of Humans, while considering optimal resource conservation, is a very important issue in modern agriculture. In such systems, inputs like chemical pesticides are slightly used. In this regard, agricultural experts are constantly seeking ways to reduce the dependence on external entities, while meeting the financial interests and social acceptability of farmers. This article aims to survey the factors affecting the adoption of sustainable low input agriculture from the standpoint of agricultural experts in Ilam province. A questionnaire was used as the main tool for this research and its validity was approved by seven professors and experts of Ministry of Agriculture. In order to assess the reliability of the questionnaire, a preliminary test was conducted using 30 questionnaires and The Cronbach alpha coefficient was calculated to be 88%. Statistical population were comprised of 170 agricultural experts from Ilam province, of which according to Cochran's formula, 313 were chosen as the sample and were selected using a stratified random sampling method with proper attribution. A statistical analysis was conducted after data extraction using SPSS version 12 software. The dependent variable in this study is Adoption of low input sustainable agriculture from the standpoint of agricultural experts in Ilam province, and independent variables include individual, educational, economical, and social factors.

A review of the biological status of Iranian dwarf honey bees (Apis florea)

Abstract: Honey bees of the Apis genus are classified regarding to their size, into three groups: large, medium and dwarf honeybees and the Apis florea species belong to the third group. Fore wing length in this species has been evaluated to be between 5-7 mm. These honey bees mostly make hives in urban areas, areas with high agricultural activity and Savannah. The distribution region of this species in Iran is the southern half of the country. Morphological studies of these species in Iran indicate that according to Bergman’s rule, there is a positive correlation between the increase in height and size in this species. Therefore, the honey bees of the southwestern areas with higher latitude and the larger size are grouped in a cluster and the honey bees in southeast parts of the country with lower latitude and smaller bees are grouped in another cluster. Other morphological and geometric-morphometric studies about the dwarf honeybees of a number of provinces in Iran has shown that honeybees of Hormozgan (with lower latitude) are different from other provinces honey bees (Ilam, Khuzestan and Bushehr) with higher latitude. Also, the length of the third and fourth tergite and the length of the proboscis, are the most variable morphological features in the Iranian dwarf honeybees. Karyotype study also included 16 chromosomes of this species in two groups: 4 metacentric chromosomes (1, 4, 7 and 11) and 12 chromosomes (including sub-metacentric chromosomes, sub-telocentric and 2 acrocentric chromosomes). Molecular study of these honey bees using microsatellite markers indicated that these honey bees have a suitable genetic condition because the great environmental diversity and interactions between genotype and environment. Regarding the morphology of the Apis florea honey bees in Asia, they have almost a different status. This species has a great importance in the pollination of crops in the southern parts of Iran and is considered as a local and national asset for the country. so, serious operations should be taken to preserve of this precious species in Iran.

Abstract- Oreochromis niloticus fingerlings were stocked in fifteen earthen ponds measuring 1000 m2 (25x40m) and 1.25m deep. The ponds were allocated into five treatments in a complete Randomized Design and labeled as T1; feed only (F) and served as a control group, T2; Compost + feed (CF), T3; Chicken litter + feed (CLF), T4; Fish rigger + feed (FRF) and T5; inorganic fertilizer (Urea +Super phosphate) + feed (IFF), where each treatment was triplicated. The T3 (CLF) treated fish group showed significantly higher growth parameters than the other treated fish groups, whereas, the feed-only treated group was the lowest. Yet no significant differences observed between fish grown in the CLF and CF treated ponds in their daily weight gain. Meanwhile, the survival rate % was generally high in all treated fish groups with the highest survival observed in T2 (CF- treated fish group) Additionally, the different pond management practices regarding the different fertilizers used in this study had fairly improved body composition of O. niloticus fish which revealed a significantly higher levels in the body moisture, fat, ash and protein content than those recorded for the fish at the start of the experiment. Generally a significantly higher phytoplankton and zooplankton number was noted in the fertilized ponds as compared to the number recorded in the feed only treated pond water. Regarding the type of the fertilizer applied, the highest phytoplankton count was noted in the pond water of the CLF treated ponds. Also it is worth stressing that the blue green and green algae were the dominating species in the pond water received fertilizers especially in the CLF treated ponds. The high natural pond productivity achieved in the current study with regard to the plenty and dominance of certain species of plankton besides the benthic materials existed in the ponds is definitely influenced by numerous types of fertilizers considering that the highest level was noticed in the CLF received ponds. Accordingly, our recorded results of chlorophyll α (ug ml-1), phytoplankton and zooplankton count and their species combination in both pond water and fish stomach contents are matched and supporting each other. It gives further verification to the superiority of using fertilizers plus supplemental feeding in producing higher fish yield rather than using artificial feed only and that the usage of CLF is preferable than the other treatments. For all treated fish groups, generally higher incidences of protozoal parasites were found in summer, autumn, and spring which was 73%, 64.5%, and 64% respectively. Yet, the results of the current study recorded parasitic infestation without a meaningful fish mortality in the experimental ponds which is supported by the high fish survivability detected in this work. The net profit was significantly higher from fish cultured in ponds received chicken liter and supplemental feeding. Therefore, overall results obtained in this study suggest that the combined application of fertilizers (namely chicken manure) and feed would be an effective technique to improve the production of a filter feeder, such as O. niloticus.

Multi criteria rules for equitable allocation of GHGs emission reduction at a country scale

Abstract— The adverse effects of climate change and GHGs emission can be combated just by application and acceptance of emissions reduction policies which are based on "Equity" concept. In addition, lack of supranational authority to impose the international agreements and no accountability for reduction efforts at country level may lead to poor implementation of emission reduction targets. As a result, this research suggests and applies fifteen different linear combinations of some principles in order to explore different kinds of burden sharing rules at a country scale for Iran. The focus is on "Horizontal Equity" on the premise of reduction target, economic development and the fulfillment of regional equity. The results of this study show that a 20% cut in Iran’s GHGs emission will lead to about 7-9% reduction of GDP over the period 2010-2020. Amongst the models examined for the appropriateness in this study, the model which assigns a greater weight to the criteria of CO2 per Added Value, demonstrated to be the most viable economical choice that is also fully supportive of less developed provinces. Iran's economy is strongly emission dependent thus application of high potentials for sustainable development and green economic growth, especially renewables, should be placed at the head of governmental plans.

Abstract— Development of cities and increase of the population in recent years and need to energy and as a result increase of economic cost of providing energy and also harmful environmental effects of pollutants resulted from combustion of the urban and nonurban consumers fossil fuels in the future will lead to challenges for the governments. It is necessary to find solutions to prevent social crises resulted from these problems. The developed countries have sought solutions for sloving similar problems and they have produced energies for different users in the cities and country and developed concurrent thermal and cooling systems. Due to economic and technical advantages like high thermal output relative to other thermal power plants (up to 90%) and as result significant saving in fuel consumption, development of such power plants reduces urban electricity transferring and distribution networks burden and investment costs and also decreases loses and improves cities environmental conditions. This action is aligned with implementation of Kyoto protocol regarding to sustainable development and reduction of greenhouse gases production. Expansion of commercial, residential and administrative spaces will lead to increase 47% in fuel consumption until 2020. This enhancement will add trillions environmental pollutants on the earth and air. In this article the environmental effects of air pollution are investigated. According to this fact the next century will be the century of energy and attention to energy crises and necessity of saving on energy consumption and considering air pollution and as result greenhouse effect and other environmental and commercial impacts so it is necessary to use concurrent thermal and power production systems in order to reduce electricity and thermal production process pollutants and study feasibility of employing this technology in power industry.

Design and Implementation a novel Low Power Consumption Lighting System

Abstract—In this paper we present a way to reduce the standby power consumption of a PIR-sensor-based lighting device. Generally although a PIR-sensor-based lighting device will turn on when motion is detected, and will turn off when the motion disappears, the device still consumes 1-3 W power when the lampis off. In our design the device consumes 0.007 W when the light is off, and is not only easy to set up but also inexpensive. Our circuit supplies the lamp with power when motion is detected; when the motion disappears it turns the lamp off, and the electric power is shut off in order to reduce the standby power. We usean MCU which receives signals from a PIR sensor which detects any individual approaching the device. The MCU controls the SSR On/Off when used as a lighting switch for shutting off the standby power. The MCU monitoring program provides automatic detection of any individual by means of the PIR sensor. The MCU has internal modules to simplify the hardware circuit design. The circuit component count, cost and powerconsumption are low.

Optimum Design of Transformer Model on contactless Energy Transmission System (CET) with Series Resonant Converter

Abstract— contactless transformer with a large air gap has small magnetizing inductance and large leakage inductance comparing with a closely conventional transformer. This paper focus on analysis, optimum design results of the winding contactless transformer using resonant converter. On the contrary to the traditional closely coupled transformer, the contactless transformer with separated primary and secondary winding is used. Therefore, the Contactless transformer with series resonant converter can reduce flow and improved system efficiency. However, this article can be used in the design and manufacture of contactless transmission systems can be significantly improved. However, that requires a contactless transmission system (wireless), is designed to optimize the transformer model. So if this system could be established in the next few years, we have witnessed the removal of wires and cables, That is a great help to preserve the environment and prevent visual disturbance and also avoid being beautiful face of nature will bring.

Energy use, Economic analysis and Mechanization Index of Onion Production in Iran

ABSTRACT— This paper studies the energy balance between the input and the output per unit area for onion in Mazandaran province of Iran. In this study, data were collected by using random sampling method for 122 face to face questioners. Results showed that the highest share of energy consumption belongs to chemical fertilizers (45.5%) followed by diesel (12.76%). The results indicated that total energy input of 42008.56 MJ ha-1 was consumed for onion production. The energy productivity and net energy value were estimated as 0.416 kg MJ-1 and -14856.92 MJ ha-1, respectively. The ratio of energy outputs to energy inputs was approximately 0.646. The benefit-cost ratio was estimated as 1.59. Mechanization degree (MD) was calculated for plowing and disk border were 100% and 20.65%, as the highest and lowest, respectively. The farms of between two to three hectares with 0.89 highest mechanization index (MI) and those between one to two hectare with 0.6 lowest MI were remarkable.

Effects of continuous triangular roughnesses on the hydraulic jump characteristics in horizontal Stilling basin

Abstract-A hydraulic jump is a surprising phenomenon in the science of hydraulics which dissipates hydrokinetic energy. Hydraulic structures like stilling basin frequently use this important characteristic of the hydraulic jump in order to dissipate energy in downstream of spillways, gates and torrents. Since dimensions of these structures are directly dependent on characteristics of the hydraulic jump therefore to make them economical many wide surveys have been conducted on characteristics of hydraulic jump and how to control them or minimize their dimensions. For example in the recent years it has been suggested that continuous roughness of the Stilling basin could be effective in reducing jump dimensions. The present study has been performed by considering this assumption and it is tried to determine level and type of this effect using laboratory experiments. To achieve this aim various experiments were performed for input numbers ranging 5-12.5 in flume that is 35 cm wide. In these experiments triangular roughnesses and their combination were installed and tested in the floor of flume in such a way that upper surface of roughnesses and spillway crest  are on the same level and some parameters like flow rate, roller length, first depth, secondary depth, jump length , water surface profile were measured. Analysis of data showed that roughnesses decrease jump length to moderate size of 57% and provide about 20% decrease in secondary depth of jump than classic type. This decrease can be caused by increase in flow turbulency level between roughnesses that causes approximately 13-fold increase in shear stress.

Investigating the factors which reduce quality of life in informal settlements (Case study: Khezr District in Hamedan City)

Abstract— Quality of life is one of the most important factors which must be paid attention to in different stages of urban planning. The improvement of life quality is the most important aim of public policies of each society and policy makers need to find the best way of resource distribution in line with people’s needs. This research aims to find factors reducing quality of life and rank them in informal settlements of Khezr.  The responses of the settlements were collected in a 367 questionnaires and analyzed with spss (ver.18). Friedman test was used to categorize the physical, economic, environmental and social factors separately so that the effective measures and actions are taken to reduce the basic problems, costs and their social effects and to increase satisfaction. The results show that these factors play a great role in low level of life quality. In fact, this research is an effort to make grounds to improve sustainable environmental conditions for the growth of health, safety, expectation and faith in informal settlements.

A new method for switching converters, DC / AC Solar Cells

Abstract—Energy Photovoltaics convert sunlight into electricity through photovoltaic cells (pvs), which is commonly called a solar cell. Solar cell is a non-mechanical device that is typically silicon alloy.

Facilities that use energy absorbed from the sun's heat into electricity is called solar thermal power facility based on a variety of existing, single-focus concentrator based on geometric shapes are divided into three categories:

Parabolic mirrors the plants that they are studs.

Plants where the recipient is located in a tower and sunlight that is reflected by mirrors Hlyvstat big name. They are parabolic dish receiver plants.

All the states of the DC power produced. In general, after stating that the DC voltage from the photocell is used to connect the plants to the distribution network, it must first be converted to a fixed frequency AC connected to the network then it can be.

In this article we will be converting the DC / AC inverter multi-level, organized the construction of a new modulation can use to reduce losses and harmonics Converters so that the energy from the solar cells can be better exploited.
