abstract in this study, we synthesized a novel template polymer by using methacrylic acid (mma) as functional monomer, ethylene glycol dimethacrylate(egdma) as cross linker, 2,2-azobisisobutyronitrile (aibn) as initiator and olanzapine as targeted molecule in the presence of chloroform and acetonitrile as solvent. the products have been characterized and confirmed by (chn)elemental analysis,...
there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...
in order to study water deficit tolerance in thymus daenensis subsp. daenensis ecotypes, seeds of eight ecotypes were collected from different locations. seedling are produced in greenhouse, and then transferred to field as an experiment of split plot design based on rcbd with three replicates. three irrigation treatments (normal irrigation, prevention of irrigation at the start of flowering 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...
Drought occurrence is one of the most important reasons for reduced yield in crops. At least in arid and semi-arid areas an efficient approach to tackle this problem is to identify and grow tolerant genotypes with the help of drought tolerance indices. The main objective of this research was to study the effects of drought on the performance of six genotypes of lentil in order to evaluate some ...
Wheat is sown mostly in Peru, areas above 3000 m altitude, under rainfed conditions and frequent drought problems during the crop cycle. It a cereal used as staple food by families of small-scale farmers who are dedicated to their cultivation, which why it necessary develop varieties with tolerance. This investigation had objectives (1) determine yield potential wheat genotypes stress condition...
abstract to determine the effects of different levels of drought stress on yield and yield components of corn hybrids as well as to determine the correlation between the characteristic and yield in different level of stress a experimental study was done in split plot with 15 corn hybrids placed in gharakheil. the main plot was contained different levels of stress(a1:irrigation after 50mm evapor...
به دلیل پدیده گرم شدن جهانی در دهه های اخیر تبدیل به یکی از عوامل مهم کاهش عملکرد گندم در مناطق خشک و نیمه خشک شده در نتیجه، ایجاد ارقام متحمل به گرما را اجتناب ناپذیر نموده است. به منظور بررسی شاخص های تحمل گرما در گندم، 144 لاین اینبرد نوترکیب حاصل از تلاقی کاز (متحمل) و مانتنا (حساس به گرما) به همراه دو والد و تعدادی از ارقام تجاری به مدت دو سال (86-1385 و 87-1386) در قالب طرح لاتیس مستطیل 1...
این تحقیق به منظور بررسی ارتباط بین صفات فیزیولوژیک، صفات زراعی و انتخاب ژنوتیپ های برتر بر اساس شاخص های مقاومت به خشکی در دو شرایط تنش و غیرتنش، در مزرعه تحقیقاتی ایستگاه تحقیقات کشاورزی اسلام آبادغرب و آزمایشگاه مرکز تحقیقات کشاورزی و منابع طبیعی کرمانشاه اجرا شد. نتایج حاصل از تجزیه رگرسیون نشان داد که در شرایط تنش خشکی هفت صفت و در شرایط نرمال شش صفت وارد مدل عملکرد دانه شدند. در هر دو شرا...
it is definitely necessary to understand the concept and behavior of causation of life insurance policies and its determinants for insurance managers, regulators, and customers. for insurance managers, the profitability and liquidity of insurers can be increasingly influenced by the number of causation through costs, adverse selection, and cash surrender values. therefore, causation is a materi...
