Renal cell carcinoma (RCC) is one of most fatal cancers. In most patients It is resistant to chemotherapy. Ferula gummosa gum, Scutellaria lindbergii, Kelussia odoratissima and Artemisia kopetdaghensis are herbs that there are some cytotoxic activity reports about them. In this study cytotoxic and apoptotic activity of these four extracts on RCC cell line (ACHN) were evaluated and compared.ACHN...

Linear (order-one) function evaluation schemes, such as bipartite and multipartite tables, are usually effective for low precision approximations. For high output precision, the lookup table size is often too large for practical use. This study investigates the so-called (M,p, k) scheme that reduces the range of input argument to a very small interval so that trigonometric functions can be appr...

باتوجه به اینکه اخیرا یکسوکنندهها در سیستمهای توزیع الکتریکی کاربرد بسیاری پیدا کردهاند، مدلسازی آنها نیز از دیدگاه مصرف کننده هایdc مورد توجه زیادی قرار گرفته است. تا کنون در این راستا مدلسازی یکسوکننده های 12پالس و 18 پالس با استفاده از روشهای متوسط گیری انجام شده است. از سوی دیگر به منظور کاهش هارمونیک های ناشی از وجود یکسوکننده ها (هم در قسمت ولتاژ بارdc وهم در قسمت جریان منبع تغذیه ac ) یک...
