rarely, do we think of cancer as “bacterial”, such that we are often told that “cancer is not contagious” persistent bacterial infections cause persistent irritation of the host’s defense systems, which when ineffective in eradication of the infection, result in a multitude of self-destructive damages. this in some cases occurs to such severity that the resulting cellular hyper-proliferation pr...
Nowadays in order to increase the reliability and other special aims, the power networks are exchanged to the large and interconnected networks. In such networks, the relays setting and coordination is complicated and needs to determine break points. Break points are the initial points in coordination process and in pervious works, different methods are proposed to finding them in interconnecte...
In this paper we investigate the use of a supervised, but self-organizing, Adaptive Resonance Theory type of neural network (Fuzzy-ARTMAP), for first break picking in seismic reflection data. First break picking is the accurate location of the leading energy pulse received by a geophone in response to a seismic shot. The performance of Fuzzy-ARTMAP is compared to our previous work with multi-la...
At high temperatures the breaking of chemical bonds becomes relatively easy and the slow step in a chemical reaction shifts to the rate at which energy can seep into the bond that is to break. This has been observed by various investigators. A new general theory of reactions is developed here to explain this limiting rate at high temperatures. In the case of cyclopropane and cyclobutane the the...
در این تحقیق سنتز آزمایشگاهی کربن فعال به روش فیزیکی در راکتور دوار با استفاده از گازهای اکسید کننده دی اکسید کربن و بخار آ ب از پوست سخت پسته به عنوان ماده اولیه مورد بررسی قرار گرفت اثر سه پارامتر دمای فعالسازی،زمان ماندودبی گاز اکسید کننده بر روی عددیدی و burn-offبا استفاده از طراحی آزمایش به روش ccd مورد بررسی قرار گرفت. این پارامتر ها دردو سطح بالا وپایین که به ترتیب برای دمای فعالسازی،زما...
