Limited fossil energy reserves in the world and increase the level of energy consumption, human always challenged to replace new energy sources. In the meantime the wind and the sun, having the advantage because of environmental pollution, and free of charge, will contribute greatly to the future of energy production in the world.. The aim of this study was to locate a suitable location for the establishment of wind farms in the province of Qazvin by considering criteria and sub criteria were effective. Given the importance of integrating information, analytic hierarchy process (AHP) to weight the selection and software layers of the software Expert choice was to implement a Geographic Information System (GIS) was used to analyze the spatial and layers. After data analysis, Qazvin province in terms of the construction of wind farms on three levels without power, average power and view available data rates were quite reasonable division The areas with the limits specified for locating wind farms and using geographic information system mapping out the entire range. The results show that fuzzy AHP method can provide more accurate according to the parameter And more precisely identify areas of limitation. It seems that the Qazvin-prone areas in the East and in the West in restricted areas closer to the city's takestan As well as North and North-West and South regions of Bouin Zahra areas are suitable areas for wind energy load.

The success rate of breeding in birds can be considered as an indispensable tool for ecology and population demographic studies. In fact, breeding is a direct measure of the quality of the habitat. This study was conducted with the purpose of breeding the endangered species, Egyptian vulture in Naghadeh. Egyptian vulture is one of the most valuable species in the world that is at the head of food pyramid and plays an essential role in the survival of other organisms in an ecosystem. Therefore, studying the breeding status of this species can be a research priority in many areas. In this study, for the first time, a record of breeding of this species was made from Naghadeh. The authors were able to identify and record locations of nesting and breeding in the county.

Role of Environmental factors on Elamite settlements in Isfahan province

per
Throughout history, humans have always been associated with surrounding environmental factors to create his own settlements. Thus, the study of environmental factors has a significant role in recognizing the characteristics of an area's establishment. The studied areas in this research are Shahsarba and Asghar in Isfahan province, which are located in plains and mountainous areas, respectively. In this research, the most important environmental factors associated with Elamite settlements in these areas are identified. Finally, it was determined that the two main factors for the establishment of these regions are Gavkhoni moorland and Funke Roodhoogh cones. Ultimately, geological studies conducted on the center of the Iranian plateau indicate the different weather conditions of the region during our study period and therefore, archeological studies will be inefficient and incomplete without considering climatic and environmental conditions of that period.

Bioaccmulation of polycyclic aromatic hydrocarbons in Barbatia helblingii from Bushehr coast

Polycyclic aromatic hydrocarbons are a large group of organic pollutants that are part of the World Health Organization's hazardous substance list. Oil spill is one of the major routes for the introduction of polycyclic aromatic hydrocarbons (PAHs) into marine ecosystems. Oil tank vessels, platforms, oil pipelines, gas and petrochemical industries, and urban and industrial wastewater are the most important contributors to oil pollution in the coastal waters of the Bushehr province. In this study, concentrations and accumulation of aromatic hydrocarbons in the Barbatia helblingii and sediments on the coasts of Bushehr at 5 stations along the Bushehr coastline were measured and calculated. The concentration of tPAHs was 935-4972 ng/g in sediments and 140 to 638 ng/g in oysters. In contrast to other parts of the world, PAHs contamination in the studied area is moderate to high. The bioaccumulation of PAHs in the oyster is not high from sediments and these compounds seem to be more concentrated from water. In addition, bioaccumulation of compounds with a lower molecular weight, such as three-ring compounds, was higher than other compounds.
