در مطالعه حاضر توانایی مدل swat2009 در شبیه سازی رواناب و همچنینن ارزیابی اثر تغییرات کاربری اراضی بر رواناب سطحی در حوضه معرف کچیک واقع در استان گلستان با مساحت 3600 هکتار بررسی شد. مدل swat توسط سرویس تحقیقات کشاورزی ایالات متحده تهیه شده و به عنوان ابزاری برای بررسی اثرات اقدامات مختلف مدیریتی بر آب، رسوب و تولیدات شیمیایی اراضی کشاورزی در مقیاس آبخیزهای بزرگ در سطح جهان مورد استفاده قرار گر...
Maturation/M-phase-promoting factor is the universal inducer of M-phase in eukaryotic cells. It is currently accepted that M-phase-promoting factor is identical to the kinase cyclin B-Cdk1. Here we show that cyclin B-Cdk1 and M-phase-promoting factor are not in fact synonymous. Instead, M-phase-promoting factor contains at least two essential components: cyclin B-Cdk1 and another kinase, Greatw...
Heavy metals (HMs) are hazardous environmental pollutants which by entering the food chain cause harm to humans, plants and other organisms. In order to study the effects of salinity and lead (Pb) and cadmium (Cd) HMs on spinach plant, a factorial, pot experiment, based on complete randomized blocks design, was carried out in 2013 in College of Agriculture, Shahrood University of Technology. Tr...
A large portion of Iran railway routes are located in sandy desert areas. Therefore, paying attention to soil stabilization methods seems essential. In present study, in parallel to introducing the deep soil mixing as an efficient and economic method of soil improvement, in the frame work of a practical example, assuming loose sandy soil parameters, feasibility of the method application is inve...
In order to investigate the effects of irrigation water salinity on root traits and absorption of sodium (Na+) and potassium (K+) by wheat cultivars, a factorial experiment, based on completely randomized design with 3 replications, was conducted under greenhouse conditions. The main factor was 7 wheat genotypes ]Ghods, Marvdasht and Bahar (sensitive to salinity) and Arg, Bam, Sistani and Sing...
در این پایان نامه به برسی سیستم های صف که دایما دچار خرابی و سپس سلامت میشون پرداخته که در آن با مشتریان ناشکیبا در سیستم با پارمتر ورود فازی مواجه هستیم و اندازه های موثر سیستمی از جمله تعداد افراد مورد انتظار در سیستم و همچنین مقدار مورد انتظار زمان اقامت در سیستم در حالت crisp و در حالت fuzzy بدست آمده و همچنین با یکدیگر مقایسه گشته است و همچنین کلیه اندازه های موثر یافت شده را با استفاده از...
we call a module essentially retractable if homr for all essential submodules n of m. for a right fbn ring r, it is shown that: (i) a non-zero module is retractable (in the sense that homr for all non-zero ) if and only if certain factor modules of m are essentially retractable nonsingular modules over r modulo their annihilators. (ii) a non-zero module is essentially retractable if and on...
the veterinary drugs residues are also important pollutants found in milk, since veterinary drugs are commonly used in cattle management. considering the role of milk in human nutrition and its wide consumption throughout the world, it is very important to ensure the milk quality. a quantitative structure–retention relationship (qsrr) was developed using the partial least square (pls), kernel p...
