Vulnerability assessment and mapping of hazard pollution is raised on as an important management strategy to protect the karst. Karstic aquifers in semi-arid regions of the West of Iran with regard to the natural conditions of the region, are susceptible to contamination. Estimation of amount and vulnerability mapping of aquifers in the karst religion of Bistoun- Paraw – Kermanshah plain agains...

Background and Objective: The childhood obesity is associated with the development of type 2 diabetes and cardiovascular disease throughout the lifecycle. The purpose of this study was to examine the relationship between adiponectin, leptin, cholesterol and triglyceride serum levels in the overweight girls after 12 weeks moderate intensity aerobic exercise training. Materials and Methods: ...
Wind erosion is the most important geomorphic process and the main cause of the landscape change in arid and semi-arid areas. This paper focuses on the Dust Storm Index (DSI) with the aim of monitoring wind erosion in Central Iran using meteorology data. The trend of standardized DSI and its three factors which are sever dust storm, moderate dust storm and local dust events were studied using M...
Crop production has a correlation with the applied water in moderate semi-arid conditions. Due to temperature and rainfall changes enhancing productivity crop are needed for limited resource In this study, maize (Zea mays L.) yields measured fields during 11 years from 2005-2006 2015-2016 were compared those simulated by Agro-ecological Zone method under environment located at north west of Ira...
abstract earthworms are an important component of soil fauna, and play a crucial role in the improvement of soil properties. however, very little is known of the interactive influence of earthworms and organic materials on soil enzyme activities, particularly in arid and semi-arid soils. the low organic matter content and the significant role of earthworms in stimulating microbiological and bio...
abstract erosion and sedimentation are the most complicated problems in hydrodynamic which are very important in water-related projects of arid and semi-arid basins. for this reason, the presence of suitable methods for good estimation of suspended sediment load of rivers is very valuable. solving hydrodynamic equations related to these phenomenons and access to a mathematical-conceptual model ...
depth of frost penetration is one of the main indices in agriculture, civil and transportation engineering. soil temperature is a function of several factors including: topography, solar radiation, air temperature, moisture content and other physical properties of soil such as thermal capacity, coefficient of heat conductivity, and specific heat. the main objective of the present paper is to de...
تیلریوزیس گرمسیری یک بیماری لنفوپرولیفراتیو پیشرونده در گاومیش و گاو می¬باشد که بوسیله تیلریا آنولاتا ایجاد می¬شود. تیلریا اورینتالیس در گروه تیلریاهای خوش¬خیم قرار دارد (تیلریا سرجنتی، تیلریا بوفلی و تیلریا اورینتالیس). تیلریوزیس خوش خیم گاو و گاومیش، دارای علائم بالینی ملایم یا بدون علائم می¬باشد. در این مطالعه 138 نمونه¬ی خون از گاومیش¬ها و 138 نمونه¬ی خون از گاوها جمع آوری و مورد آزمایش ق...
