Devaluation has different effects on the structure of trade patterns in countries which have a fixed exchange rate regime. The experience of devaluation in many countries has clearly shown that devaluation policies have not always led to the improvement of their trade pattern structures. Some empirical studies have revealed that after employing devaluation, the real rate of money in some nation...
امروزه با توجه به افزایش تقاضا و کاهش منابع انرژی، ذخیره سازی انرژی امری ضروری به نظر می¬رسد و مواد تغییر فاز دهنده وسیله مناسبی برای این منظور بشمار می¬روند. نقطه ضعف این مواد پایین بودن هدایت حرارتی آنهاست و یکی از راههای برطرف کردن این عیب، افزودن نانوذرات به این مواد است. در این پژوهش اثر نانو ذرات بتا سیلیکون کاربید بر خواص حرارتی ماده تغییر فاز دهنده پلی اتیلن گلیکول مورد مطالعه قرار گرفت...
To study human-to-human transmissibility of the avian influenza A (H7N9) virus in China, household contact information was collected for 125 index cases during the spring wave (February to May 2013), and for 187 index cases during the winter wave (October 2013 to March 2014). Using a statistical model, we found evidence for human-to-human transmission, but such transmission is not sustainable. ...

The aim of this paper is two folds: 1- To compare the level of technological advances in Iran's Automotive Industry with that of its competitors globally. 2- To compare the relative technological advances of Iran’s Auto Industry with other sectors of the Iranian economy. To measure the level of technological advances, we have used the Atlas Model of Technology. The results indicate that the lev...
Purpose-The research aims at evaluating the standardization/adaptation of international marketing strategy in Iran multinational companies (MNCs) based a model in which the impact of external environmental variables on the marketing mix internal variables (i.e. Product, Promotion, Price and Place) is considered, while in the previous researches no attempt was done to examine the interdepende...
It is an exciting time to be an ecologist. Over the past several decades, our discipline has matured from one focused on the assembly of case studies based on natural history, to one that has seen improved conceptual frameworks and mathematical models that help explain ecological phenomena from species coexistence to elemental cycling. The maturation of our discipline has been fostered by many ...
