Study of Permanent Magnet Bearings and their Stiffness

functional study of p0 proteins of two cereal yellow dwarf viruses (cydv-rpv and cydv-rps) and identification of their cellular partner

نقش سرکوبگری پروتئین p0 در دو پولروویروس کوتولگی زردی غلات cydv-rpv) و (cydv-rps، متفاوت در شدت بیماریزایی، مورد مطالعه قرار گرفت. نتایج نشان داد که هر دو پروتئین p0 p0cy-rpv) و (p0cy-rps قادر به سرکوب خاموشی آر ان ای ایجاد شده توسط ترادف های تراژن سنس و تکرار معکوس در n. benthamiana هستند. نشان داده شد که هر دو پروتئین p0 می توانند تخریب پروتئین argonaute-1 را تسهیل کنند. علاوه بر این، تمایل م...

Design and optimization of dc brushless permanent magnet motor

Electric motors that have found wide application in various sectors of industry Have unique features such as high reliability, high efficiency, quick acceleration and have small sizes. Brushless DC motors meet these requirements well. In this study, the design of a brushless DC motor speed limits for the particular application at 1800 rpm that can be equivalent to 140 watts output was provided....

Brushless Permanent Magnet Servomotors

Electrical motors drive a variety of loads in today’s world. Almost every industrial process relies on some kind of electrical motors and generators. There exist billions electric motors used in different applications all over the world. Majority of them are small fractional HP motors use in household appliances. However, they used about 5% of the electricity used by the motors. Three phase mot...

a genre analytic study of research papers written by bilingual writers and their beliefs: a case of persian-english writers

تحقیق حاضر گزارشی است از تحلیل بخش مقدمه دو دسته از مقالات که عبارتند از: 11 مقاله از دو نویسنده دوزبانه فارسی زبان, که شامل مقدمه 4 مقاله به زبان انگلیسی و چاپ شده در مجلات بین المللی, مقدمه 3 مقاله به زبان انگلیسی و 4 مقاله به زبان فارسی چاپ شده در مجلات داخلی می شود؛ و 12 مقاله از محققان خارجی که در مجله applied linguistics به چاپ رسیده است. مبنای تئوری این تحلیل ها نظریه سوئلز (1990) یا هما...

Controlled Permanent Magnet Drives

The considered converter-fed permanent magnet motor could alternatively be operated in two basically different states − the vector control mode or alternatively the brushless dc, also known as electronically commutated mode. Several quality aspects concerning the system performance have been comparatively investigated in practical as well as theoretical manner. Focus is thereby given to the num...
