A permanent magnet synchronous generator (PMSG) variable speed wind turbine connected to an electrolyzer and a battery model system is presented in this paper. Hydrogen gas could be produced from the model system, when a variable wind speed is applied to the PMSG driven variable wind turbine. The simulation results presented shows the nature of some of the variables of the PMSG wind driven turb...

Background and Objective: Aloe buettneri (A), Dicliptera verticillata (D), Hibiscus macranthus (H) and Justicia insularis (J) are medicinal plants whose leaf mixture aqueous extract (ADHJ) is locally used to regulate the menstrual cycle and to treat infertility in women. This study was designed to evaluate the ovarian follicles growth inducing potential of ADHJ in Pregnant Mare Serum Gonadotrop...

The efficiency of medroxyprogesterone acetate (MAP) sponges in combination with either pregnant mare serum gonadotrophin (PMSG) or cloprostenol (PGF2α) for inducing and synchronizing the estrous cycle in non-lactating Kivircik ewes was investigated during the natural non-breeding season. All ewes (n = 69) were treated with 60 mg MAP sponges for 12 days. In addition, each ewe received an intramu...

A total of 88 thoroughbred mares were diagnosed with clinical ovarian quiescence and subjected to four treatment regimens. Using PMSG, hCG or combinations of both. A high dose combination of 5,000IU PMSG with 5,000IU hCG showed significantly higher rates of marked estrus and ovulation induction (P<0.01) as well as conception rates (P<0.05). In the present study, the administration of a high-dos...

Procedures have been developed for the purification of pregnant mare serum gonadotropin (PMSG) and its a and jl subunits. The procedure for the hormone purification involves three steps of column chromatography on Sephadex G-100, DEAE-Sephadex A-50, and hydroxyapatite. The preparation of subunits involves the dissociation of PMSG with 10 M urea followed by their separation by chromatography on ...

به کمک شبیه ­سازی دینامیک مولکولی می ­توان تحلیل کوتاه مدت در مقیاس زمانی چند ده پیکوثانیه ­ای را برای مواد آسیب دیده­ی تابشی مورد مطالعه قرار داد. بر همین مبنا این ­سازی، تعداد تعادلی عیوب نقطه بین ­نشین و تهی ­جای مختصات مکانی آن­ها آهن- آلفا دست آورده شد. سپس با استفاده از نتایج حاصل شده، مونت کارلوی جنبشی شیء منظور بررسی تأثیر بازپخت آلفای انجام نشان دادند که یکنواخت دیده­ ی تنها خوشه جای ب...

Thir ty-one 3-year-old Angus cows and 23 2-year-old Angus heifers were randomly allotted to two t rea tment groups to examine the influence o f PMSG on endocr ine and reproductive responses. Sixteen cows and 11 heifers received a single subcutaneous inject ion of 2,000 IU PMSG on day 17 o f the estrous cycle (Trt 17); 15 cows and 12 heifers received 1,500 IU PMSG on day 5 and 2,000 IU on day 17...

Two experiments were conducted to determine the effect of exogenous gonadotropins on follicular development in gilts actively immunized against gonadotropin releasing hormone (GnRH). Four gilts, which had become acyclic after immunization against GnRH, and four control gilts were given 1,000 IU pregnant mare serum gonadotropin (PMSG), while four additional control gilts were given saline. Contr...
