SExtended Abstract Introduction and Objective: Small grain cereals such as wheat, are affected by types of destructive environmental factors such as abiotic and biotic stresses that severely reduce crop yields. To cope with these conditions, transcription factors cause plant resistance to these stresses by activating or suppressing the expression of genes involved in the resistance responses....
In this paper, to account for the effect of water stresses in the various growth stages under deficitirrigation, the multiplicative, seasonal and minimal approaches are integrated in the BUDGETmodel. To evaluate the model, the simulated yields for winter wheat (was grown in Sharif Abaddistrict) under various levels of water stress were compared with observed yields. The resultshowed, simulated ...

New quinazoline derivatives were prepared by one pot reaction of anthranilic acid, acetic anhydride and primary amines, under ultrasonic irradiation. As a result, Ultrasonic irradiation has led to affordable, clean synthesis of a variety of target compounds in much higher yields, than traditional methods. This method has numerous advantages: such as higher yields, shorter reactions time, and ea...

در این پژوهش امکان ایجاد پوشش های نانو کامپوزیتی fe-tic بر سطح زیرلایه های فولادی به روش پوشش دهی لیزری مورد بررسی قرار گرفت . به منظور آماده سازی مواد اولیه و ایجاد ذرات نانو کریستال تیتانیم و کربن فعال شده از روش آلیاژسازی مکانیکی استفاده شد . ذرات تیتانیم و کربن خالص به نسبت استکیومتری مشخص مخلوط و توسط آسیا ماهواره ای آسیا شد. مخلوط نانو کریستال تیتانیم و کربن فعال شده با پودر آهن خالص مخل...
yield gap analysis provides an essential framework to prioritize research and policy efforts aimed at reducing yield constraints. to identify options for increasing chickpea yield, the ssm-chickpea model was parameterized and evaluated to analyze yield potentials, water limited yields and yield gaps for nine regions representing major chickpea-growing areas of razavi khorasan province. the aver...
In this article we discuss examples of fractal $omega$-operads. Thus we show that there is an $omega$-operadic approach to explain existence of the globular set of globular setsfootnote{Globular sets are also called $omega$-graphs by the French School.}, the reflexive globular set of reflexive globular sets, the $omega$-magma of $omega$-magmas, and also the reflexive $omega$-magma ...
A protocol for the synthesis of 1,4-dihydropyridines (Hantzsch type-products) was developed by means of a three-component condensation of an aldehyde, a β-dicarbonyl compound, ammonium acetate and nano Al2O3/KF as catalyst. This reaction was carried out under different conditions including i) solvent-free ii) and reflux in different solvents. In all conditions, the desired products were obtaine...
