Azospirillum brasilense is one of the N2-fixing microorganisms which, in symbiosis with the roots of cereals and other graminae, enhances growth and development of plants. In this research, wheat seeds (Triticum aestivum) of three cultivars (Ghods, Roshan and Omid) were inoculated with Azospirillum strains (Sp7 and Dol). Inoculation increased growth parameters and yield of wheat cultivars, the ...
experiments were carried out in which the dependence of the fractional softening on temperature, time and strain rate was determined in a 304h stainless steel. three prestrain ranges were identified pertaining to three different post-deformation softening behaviors: 1) prestraining to below the drx critical strain: strongly strain dependent softening by srx alone with softening kinetics control...
Since tubes have numerous industrial applications, different attempts are focused on the severe plastic deformation processes of tubes. As an illustration, tube channel pressing (TCP) is an attractive process for this purpose since it can be used for processing of different sizes of tubes. However, more attempts are needed to improve the outcomes of TCP. For example, imposing of a greater strai...
به منظور مطالعه اثر محلولپاشی باکتریهای محرک رشد و متابولیتهای (شامل سیدروفور، اکسین، جیبرلین و برخی اسیدهای آلی) آنها در مقایسه با تلقیح ریشه بر میزان کلروفیل، جذب عناصر معدنی و عملکرد برنج رقم هاشمی، آزمایشی در دانشکده کشاورزی دانشگاه گیلان در قالب طرح بلوک کامل تصادفی در 4 تکرار در سال 1389 به اجرا درآمد. تیمارها در این تحقیق عبارت بودند از: بدون محلولپاشی و بدون کود (تیمار شاهد)؛ بدون م...
stability studies play a critical role in assuring product quality at all points in the vaccine life cycle and havea major impact on the success of immunization programs worldwide. the purpose of stability study isdetermination of the vaccine quality under the variety of environmental factors and to establish a re-testperiod or a shelf life and recommended storage conditions. in this study thre...
protection of animals immunized against bacillus anthracis is usually demonstrated by challenging with an appropriate dose of a strain of bacillus anthracis that is lethal to unvaccinated animals inoculated at the same time. in this study the protective efficacy in anthrax vaccine (34f2 sterne strain spore) was evaluated in sheep, goats and guinea pigs challenged with subcutaneous inoculation o...
Introduction:The workplace is considered a strategic location for physical, social and especially mental health promotion. Mental healthdisorders and job stress or strain, each,can cussesindividual injuriesand reduce in organizationalperformance. This study was designed and performed to determine association between mental health and job strain among office workers who were working in Qom provi...
Determination of critical points on hot stress-strain curve of metals is crucial in thermo-mechanical processes design. In this investigation a mathematical modeling is given to illustrate the behavior of metal during hot deformation processes such as hot rolling. The critical strain for the onset of dynamic recrystallization has been obtained as a function of strain at the maximum stress. In a...
