the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation

in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.

Verification of Low Latitude Ionosphere Effects on WAAS During October 2003 Geomagnetic Storm

The Federal Aviation Administration’s Wide Area Augmentation System (WAAS) provides high integrity GPS-based precision navigation service to users in the conterminous United States. In October 2003, only four months after WAAS was commissioned, a series of coronal mass ejections from the sun triggered one of the strongest geomagnetic and ionospheric storms of the solar cycle. WAAS user integrit...

investigation of effective parameters on the rigidity of light composite diaphragms (psscb) by fem

در این رساله با معرفی سقف های psscb متشکل از ترکیب ورق های فولادی ذوزنقه ای و تخته های سیمانی الیافی به عنوان سقف های پیش ساخته (سازگار با سیستم سازه ای قاب های فولادی سبک) به بررسی پارامترهای موثر بر صلبیت سقف، پرداخته می شود. در تحقیق حاضر ابتدا به مدل سازی دو نمونه سقف آزمایش شده، به روش اجزاء محدود با استفاده از نرم افزار تحلیلی abaqus ver 6.10 پرداخته شده است. نمونه های ساخته شده تحت اعما...

A large - scale traveling ionospheric disturbance during the magnetic storm of 15 September 1999

[1] Using a comprehensive data set and model calculations, we have investigated a prominent large-scale traveling ionospheric disturbance (LSTID) observed in Japan ( 37 –16 MLAT) on 15 September 1999, during a recovery phase of sequential storms. The LSTID was detected at 2300–2400 LT (1400–1500 UT) as an enhancement of the 630-nm airglow intensity (50!350 R), a decrease in the F layer virtual ...
