abstract knowledge of the coordination of the agricultural activities in every region with the weather and climate condition of that area is necessary for any kind of agriculture activity. therefore, understanding the climate and analyzing the ecophysiological characteristics of plants are the most important factors in production. saffron is one of the most valuable plants, which is planted in ...

Background: The rejected films in radiography may be responsible for an unnecessary increase in the radiation dose to the population. The effective dose to population is a very important factor in estimation of stochastic risk in radiology. The main goal of this study was to determine the effective dose to members of the public due to rejected films in diagnostic radiology departments in the No...

in this study impact of climate change on operation of gorgan rud basin's dams was evaluated. in this regard temperature and precipitation of the basin for 2011-2035 periods were downscaled using sdsm model and cgcm3-a2 outputs. results showed that annual temperature would increase 0.05°c and annual precipitation would decrease about 4percent. to predict streamflow of the gorgan rud basin ...
