این رساله را با مفاهیم و قضایای اساسی آغاز می کنیم. سپس عملگر اسکتن و trace class را تعریف می کنیم و نشان می دهیم یک جبرژردان از عملگرهای شبه پوچ توان و فشرده شامل عملگر trace class ، زیرفضای پایا دارد. هم چنین نشان می دهیم یک جبر ژردان از عملگرهای شبه پوچ توان اسکتن مثلثی شونده است. در نهایت به بررسی ویژگی های عملگرهای کراندار که در شرایط طیفی جمعی و ضربی صدق می کنند می پردازیم و نتایج آنها را...
To evaluate effect of different irrigation regimes and mycorrhizal fungi on the growth and yield of mungbean NM92 [Vigna radiata (L.) Wilczk], a field experiment was conducted in split plot arrangements using randomized complete block design (Irrigation after 50, 100, 150 and 200 mm evaporation from pan class A as main plots and mycorrhiza species, Glomus mosseae, G. intraradices and a non-inoc...
A comprehensive analysis of interfacial water molecules in the structures of 109 unique protein-DNA complexes is presented together with a new view on their role in protein-DNA recognition. Location of interfacial water molecules as reported in the crystal structures and as emerging from a series of molecular dynamics studies on protein-DNA complexes with explicit solvent and counterions, was a...
در این تحقیق اثر ریتانسرین ( آنتاگونیست گیرنده سروتونینی 5-ht2) بر فراموشی ناشی از اسکوپولامین (آنتاگونیست گیرنده موسکارینی کولینرژیک ) در ماز آبی موریس morris water maze,mwm) ) بررسی گردید .
Two field experiments were conducted in 1996 at the experimental station, College of Agriculture, Shiraz University at Badjgah. Fourteen cultivars consisting of eight hybrids and six open pollinated cultivars were grown in two randomized complete block designs with four replications. The well-watered experiment received water when evaporation reached 65±5 mm from class A evaporation pan. The wa...
Background and objectives: Essential oils (volatiles) are aromatic oily liquids prepared from different parts of plants and demonstrate various therapeutic and cosmetic properties. The dissolution of essential oils are not desirable in water, therefore the aim of this research was evaluation and selection the best co-solvents for increasing their solubility and bio availability...
Introduction: Drought is recognized as a slow, creeping phenomenon that can accelerates the expansion of desertification in different regions especially in arid and semi-arid area with its effect on the agricultural sectors, water resources and vegetation cover. Positioning of Iran in the world arid and semi-arid belt is exposed to drought and water crisis and desertification. Drought monitorin...
We consider the problem of sharing water among agents located along a river. Each agent’s benefit depends on the amount of water consumed. An allocation of water is efficient when it maximizes total benefits. To sustain an efficient water allocation the agents can compensate each other by monetary transfers. Every water allocation and transfer schedule yields a welfare distribution, where an ag...
increasing the efficiency of water use is one of the main topics of sustainable agriculture in arid and semi-arid. the use of some materials such as superabsorbent polymers increase water storage in the soil and thus reduce the water use. increase water storage in the soil to reduce the effects of drought and saline soil. in order to evaluate the effect of super absorbent polymer on survival an...
Background & Aims of the Study: Water resources are useful or potentially useful. Uses of water are included agricultural, industrial, household, recreational and environmental activities. The majority of human uses require fresh water. Rivers are parts of this fresh water that play a very important role in the water cycle, acting as drainage channels for surface water. Hence, ...
