Determining the origin of raining air masses in Iran and the Middle East Countries using isotopic composition (18O and 2H) of Precipitations
the Middle East meteoric water line (MEMWL - δ2H = 6.86 δ18O + 9.4) and Iran meteoric water line (IMWL - δ2H = 6.56 δ18O + 4.25), and to recognize the origin of raining air masses in Iran and the Middle East (ME) Countries. The wide range of isotopic...
بررسی کانه زایی مس و آلتراسیون های موجود در محدوده برناباد بردسکن، استان خراسان رضوی
چکیده :
مطالعات کانی شناسی و ژئوشیمیایی در منطقه برناباد حاکی از زون بندی کانه سازی پلی متال مرتبط با نفوذ توده های پلوتونیک در منطقه می باشد. مطالعه و آنالیز از 161 نمونه (به روش ICP-ME) از رخنمون های برجای واحدهای سنگی، کانی زایی ها...
Comparison of coupling constant by using momentum spectra and event shape variables in different interactions
We describe in this paper the QCD prediction to calculate the strong
coupling constant by using event shape variables as well as momentum spectra. By
fitting the dispersive model and employing our parameters, on event ...
Comparison of Growth Performance and Carcass Characteristics of Broiler Chickens Fed Diets with Various Energy and Constant Energy-to-Protein Ratio
This experiment was conducted to compare the effect of diets with various energy constant ME: CP ratio on performance, nutrients efficiency and carcass characteristics of broiler chickens. In a completely randomized design experiment, five starter...
