in this thesis,spin dependend transport and electron transport through of ng/sg(graphene/ superconductor graphen) are studied in the junction of ng/fgt/sg. due to andreev reflection conductance increases in the presence of superconductor graphene.also, by applying a voltage gate on a superconductor, fermi level shifts and the conductance is independent of ferromagnatic substrate. also, the cond...

ژن zfx کد کننده یکی از اعضای خانواده پروتئین های انگشت روی می باشد که به عنوان تنظیم کننده خود نوزایی در چندین نوع سلول های بنیادی عمل می کند. علاوه بر این، بیان این ژن به طور غیر نرمال در چندین سرطان افزایش می یابد و با درجه بدخیمی ارتباط دارد. در این مطالعه به منظور بررسی نقش zfx در پاتوژنز آستروسیتوما، بیان آن با استفاده از روش real time rt-pcr در 25 نمونه بافت توموری آستروسیتوما با درجات مخ...
