in order to evaluate the effects of methanol on germination percentage, germination speed index, plumule and radicle length, plumule and radicle dry weigh, vigor index and consumed endosperm of bean in condition of water deficit, a factorial experiment done based on completely randomized design with three replications. the first factor was different levels of methanol included 0 (control), 5, 1...
this experiment was conducted using 216 male chicken (ross 308) to evaluate the effects of organic selenium and sodium bicarbonate supplementation on blood parameters, growth performance and carcass characteristics in heat stress condition. birds were reared under same condition and fed with similar diets till 28 d of age. at 28 days of old, broiler with similar weight were regrouped within die...
Factor price equalization (FPE) is a central theme in trade theory, for which [Dixit, A.K., Norman, V., 1980. Theory of International Trade, Cambridge University Press, London] establish the necessary and sufficient condition (the Dixit–Norman condition). [Deardorff, A.V. 1994.

با توجه به اهمیتی که رودخانه ها در تأمین منابع آب بشر دارند، آگاهی از میزان رواناب و بار رسوبی که حمل می کنند می تواند بشر را در برنامه ریزی های آینده در منابع آب یاری نماید. امروزه، کاربرد روش های سیستمی به خاطر توانایی پردازش حجم بالایی از داده ها در مدت زمان کوتاه در برنامه ریزی منابع آب در حال افزایش می باشد. از آنجایی که مدل swat2009 یک مدل جامع و کامل جهت ارزیابی فرآیندهای هیدرولوژیک در س...
Chronic toxicity test was conducted for 28 days with post larval stages of Penaeus indicus to arsenic for studying the changes associated with growth pattern, specifying the length, weight and condition factor. Arsenic exposures produced significant (P < 0.05) effect in terms of length, weight and deteriorated the condition factor of the test animal. Differentiation in relation between the cond...
This research was conducted at Research Farm of Isfahan University of Technology to examine the relations among phonologic, morphologic and physiologic traits and their effects on grain yield of 20 oat (Avena sativa L.) genotypes. A randomized complete block design with three replications was used in each irrigation treatment (i.e. irrigation after 70±3, and 130±3 mm evaporation from class A pa...
