This study was conducted to evaluate fertili ty in 160 day-old gilts. In Experiment 1, 28 gilts in the following five groups were injected with (1) vehicle, (2) 500 /ag of a synthetic gonadotropin releasing hormone (GnRH) anal ogne [ D-Ala 6-des-Gly-NH2101 LH-RH-ethylamide (AY 25205), (3) a cbmbination of 400 IU of pregnant mares' serum gonadotropin and 200 IU of human chorionic gonadotropin (4...

This paper presents the expansion of power quality for variable speed Wind Power System (WPS) using Permanent Magnet Synchronous Generator (PMSG) and Trans Z-Source Inverter. The PMSG is having compact collection and dimensions, compare to Induction Generator. Induction Generator needs the grid power, then only start the power production. But without take up the grid power PMSG should produce t...

We have observed that levels of the antioxidant glutathione (GSH) and protein levels of the catalytic and modifier subunits of the rate-limiting enzyme in GSH synthesis, GCLc and GCLm, increase in immature rat ovaries after treatment with gonadotropin. The goals of the present studies were to delineate the time course and intraovarian localization of changes in GSH and GCL after PMSG and after ...

Wind energy, a kind of non-conventional energy source and environmental fresh energy, is widely studied nowadays. Directly driven wind turbine permanent magnet synchronous generator (D-PMSG) plays a vital role in the latest small-scale wind Power technology. This paper presents the modeling and simulation of a 12kW direct driven Permanent Magnet Synchronous Generator of Wind Power. This model c...

There was no difference in frequency of maturation of oocytes obtained from mice hypophysectomized for 2 weeks compared to those from sham-operated or untreated (control) animals of the same age. By 7 weeks, and also at 12 and 17 weeks, the incidence of polar body formation in vitro was significantly reduced. The number of oocytes which remained meiotically inactive in culture was increased at ...

Pregnant mare's serum (pms) is being used by various workers for inducing ovulation in the immature rat (Cole, 1936; Williams, 1945; Zarrow, Caldwell, Hafez & Pincus, 1958; Strauss & Meyer, 1962; McCormack & Meyer, 1962). This report is concerned with the comparison of pmsg preparations manufactured by three different companies as regards their ability to cause ovarian growth and ovulation in t...

In a high proportion of new energy grids or 100% source power grid, the dynamic performance PMSG under fault conditions is very important. However, current small signal model lacks detailed and deep analysis permanent-magnet synchronous generator (PMSG)-based wind generation LVRT control. Here, pre-fault, after failure recovery stages are established. This paper employs linear analyses to chara...

Ucar O. , M. Kaya, S. Yildiz , F. Onder , M. Cenesiz , M. Uzun: Effect of Progestagen/PMSG Treatment for Oestrus Synchronization of Tuj Ewes to be Bred after the Natural Breeding Season. Acta Vet. Brno 74, 2005: 385-393. The aim of this study was to investigate the effect of pregnant mare serum gonadotrophin (PMSG) and progestagen sponge on oestrus synchronization of Tuj ewes mated after breedi...
