چکیده روش های متعددی برای برآورد رواناب حاصل از بارش در حوضه های آبریز وجود دارد. یکی از این روش ها استفاده از مدل های هیدرولوژیکی است. با استفاده از مدل های هیدرولوژیکی و شبیه سازی فرآیندهای هیدرولوژیکی می توان با صرف کمترین زمان و هزینه، رواناب و مولفه های دیگر چرخ? هیدرولوژیکی را برآورد کرد. از آنجا که در حوضه های آبریز اندازه گیری تمام کمیت های مورد نیاز برای تحلیل رواناب ممکن نیست، انتخاب...

during the recent decades, substantial changes are made in the borders and contents of physiology as a basic course for the students in medicine. here some strategies are presented to preserve the classical and integrative approaches in teaching physiology, while these approaches extent our knowledge to molecular, sub-cellular and cellular levels.
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...

The negative effects of a high level of government debt are now generally acknowledged. The extensive borrowing of past years has enlarged the share of interest payments in government spending, thus restricting the scope for future fiscal policy action. There is very little prospect of being able to initiate economic recovery by way of expansive fiscal policy. High deficits and rising debt rati...
We address the problem of integrating classes that are developed independently. We propose to factorise the intensional and extensional dimensions of classes and let them be organised in separate hierarchies. Class integration becomes the problem of integrating extent graphs, and to describe relations between the properties of the classes to be integrated. Our approach may be seen as extending ...
