Toxoplasma gondii is one of the most prevalent parasitic infections in world. Rh, NED and Me49 are of the most prevalent clonal types of the parasite isolated till now. Differences in pathogenicity and virulence of different types have been investigated in different studies. No controlled study was performed to compare the ability of different types to initiate humoral immune response. We inves...

Tea (C. sinensis L.) is the most important beverage crop in Iran and genetic base of current Iranian tea shrubs were achieved from three mass seeds namely: Dhongan, Batjan and Raighur. In this study, genetic diversity of 30 cultivated tea clones were evaluated using 45 RAPD markers and 13 morphological and 4 chemical characters respectively. Sixteen and of 45 markers produced 96 bands that 89 b...

کیفیت توان یکی از نگرانی های مهم مهندسین سیستم های قدرت میباشد. از طرفی هارمونیک ها به عنوان یکی از پدیده- های کیفیت توان در نظر گرفته میشوند. از این رو شناسایی شکل موج جریان و ولتاژ برای طراحی فیلترها جهت حذف و یا کم کردن اثر هارمونیک ها در یک سیستم قدرت ضروری است. این پایان نامه دو روش جدید برای آشکارسازی هارمونیک ها در سیستم های قدرت ارائه میدهد. اگر چه تخمین پارامترهای هارمونیکی در اثر غیر ...
