the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...

ژنوتیپ ها تحت دو شرایط تنش و بدون تنش خشکی در قالب طرح بلوک های کامل تصادفی در سه تکرار در منطقه بیستون در سال زراعی 91-1390 ارزیابی شدند. نتایج تجزیه واریانس نشان داد که تفاوت بین ژنوتیپ ها در شرایط بدون تنش برای همه صفات به جزء برای تعداد پنجه، وزن کل بوته ها و عملکرد کاه معنی دار بودند، و در شرایط تنش نیز برای همه صفات به جزء برای نسبت طول پدانکل به ارتفاع و تعداد پنجه بارور معنی دار بودند. ...

determination of uranium in natural water and complex solutions using ion exchange chromatography: a combined procedure using ion exchange chromatography and uv-vis spectrophotometry techniques has been developed to measure uranum in natural water and complex solutions. after conditicing , one hundred milli liters of sample solutions have been passed through an ion exchange column,pachked with ...

در بهار سال 1391، به منظور تعیین بهترین شاخص‎های کمی تحمل به خشکی در ژنوتیپ‎های چغندرقند، آزمایشی به‎صورت طرحکرت‎های خرد شده در قالب بلوک‎های کامل تصادفی در سه تکرار در ایستگاه تحقیقاتی مرحوم مطهری مؤسسه تحقیقات چغندرقند درکمال‎شهر کرجانجام گرفت. دو تیمار آبیاری شامل آبیاری نرمال پس از 90-80 میلی‎متر و آبیاری با اعمال تنش پس از 270 میلی‎متر تبخیر از تشتکتبخیر کلاس A در کرت‎های اصلی و 36 ژنوتیپ ...

For evaluation of spring wheat cultivars using drought resistance indices, two separately experiments were done in split plot basis of Random Complete Block Design with four replications. This research was done with complete irrigation (control) and drought stress that start before and after of booting stage in research farm of Agriculture Faculty, University of Tabriz. Basis grain yield in irr...

this study investigated the potential role of age in inductive and deductive grammar learning among iranian foreign language learners. the experimental population consisted of our randomly selected samples including two groups of children (with age of exposure to english within 8-13), and two groups of adults (with age of exposure to english within 11-13). thus, the comparison was between ch...

In order to determine the most effective indices for quantifying drought tolerance and identify genotypes that are tolerant to water stress in bread wheat, 50 bread wheat genotypes were compared in a randomized complete block design with three replications under both the non-stress dry farming with two complementary irrigation and the water stress dry farming conditions in Khorramabad, Iran. An...

به منظور ارزیابی تحمل به خشکی در ژنوتیپ‌های گندم نان، تعداد 20 ژنوتیپ در قالب طرح بلوک‌های کامل تصادفی با سه تکرار در شرایط بدون تنش و تنش رطوبتی در مزرعۀ تحقیقاتی دانشکدۀ کشاورزی دانشگاه رازی در سال زراعی 90-1389مورد بررسی قرار گرفتند. بر اساس عملکرد دانه در شرایط تنش و بدون تنش، 14 شاخص تحمل به خشکی شامل شاخص تحمل به تنش (STI)، حساسیت به تنش (SSI)، تحمل (TOL)، میانگین بهره وری (MP)، میانگین ه...
