Abstract Background Heat stress is a major environmental factor that could induce premature leaf senescence in plants. So far, few rice senescent mutants have been reported to involve heat tolerance. Findings We identified 50 ( psl50 ) mutant exhibited higher susceptibility with decreased survival rate, over-accumulated hydrogen peroxide (H 2 O content and increased cell death under compared th...
section{introduction} the concept of {sl cartan geometry} appeared at the beginning of the twentieth century, when {e}lie cartan was working on the so-called {sl equivalence problem}, the aim of which is to determine whether two given geometric structures can be mapped bijectively onto each other by some diffeomorphism. this problem can be considered in many different contexts, such as ...
رفتار شیمیایی فسفر در خاک تابعِ پیچیده‌ای از عوامل مختلف از جمله اکسیدهای آهن است. هدف این پژوهش بررسی تأثیر اندازه (نانو و غیر نانو) و غلظت ذرات اکسید آهن بر گونه‌بندی و فراهمی فسفر برای گیاه بود. پژوهش به صورت طرح آزمایشی فاکتوریل در قالب طرح پایة کاملاً تصادفی در چهار تکرار و پنج سطح اکسید آهن غیر نانو و پنج سطح اکسید آهن نانو (0، 500، 1000، 5000، 10000 mgkg-1) انجام پذیرفت. گونه‌بندی فسفر به ...
Introduction: Hydatidosis is one of the most important zoonotic diseases in the world. The main issue of the treatment of this disease is elimination of protoscolices during surgery to prevent from causes of secondary cysts. The aim of this study was to evaluation of scolicidal effects of Cornus mas (C mas) and Lavandula officainalis (L officainalis) extract in vitro. Materials and Methods: In ...
there is less published research about how teachers in efl contexts respond to students who are relatively less mature and less competent l2 writers. while writing researchers have examined various issues concerning peer and teacher response in writing-oriented classes, little research has centered on the effect of collaborative tasks particularly dictogloss on writing skills. output collaborat...
در این پژوهش واکنش تغذیه‌ای نارنگی انشو با پایه سوینگل‌سیتروملو به خاک‌های آهکی شرق مازندران بررسی شد. آزمایش گلدانی به مدت دو سال در قالب طرح بلوک‌های کامل تصادفی با هفت خاک دارای مقادیر متفاوت کربنات کلسیم معادل از 2% تا 45 درصد در 4 تکرار جمعاً با 28 گلدان انجام شد. نتایج نشان داد که بیشترین میانگین وزن خشک اندام هوایی از خاک جنوب ساری با مقدار آهک کل 14 درصد، آهک فعال 5 درصد حاصل شد و در خاک...
Three species of L. tropica, L. major and L. infantum are known as main causal agents of leishmaniasis have been reported in Iran. Since cutaneous leishmaniasis (CL) is endemic in North East of Iran, in the present work, 50 Leishmania positive isolates from human cases in Mashhad (Center of Razavi province, North East of Iran), were genotyped by means of polymerase chain reaction-restriction f...
Nucleus accumbens (Nac) has been considered as a center for the induction of drug dependence. Since a high concentration of the enzyme, nitric oxide synthase (NOS) has been found in the Nac, and this fact that the role of nitric oxide (NO) in acquisition and expression of drug dependence has become clear in recent years, therefore in this study the effects of intraaccumbal injections of L-argin...
