The main aim of the project is to use an ac/dc/ac power converter to extract power from variable speed Permanent Magnet Synchronous generator (PMSG) and feed it to supply a standalone load. The output voltage and frequency of the PMSG is variable in nature due to non uniform wind velocities . In order to condition and feed it to a load we need power electronic interface. The variable three phas...

The effects of progestogen-gonadotropin treatment on estrous response, ovulation rate and lambing response of crossbred ewes were examined at two times during the anestrous season (May-June and July-August). Each ewe group was treated with progestogen pessaries for 16 days and injected with 750 IU pregnant mare serum gonadotropin (PMSG) on days 17 and 32 to induce two consecutive estrous period...

such as pregnant mare serum gonadotropin (PMSG) and human menopausal gonadotropin (hMG) is a well-established practical technique. The purpose of this technique is to achieve enhanced commercial production of genetically meritorious individuals in the livestock industry, to retrieve a number of oocytes and early embryos in various research fields including genetic engineering, and to treat medi...

In this paper, a wind energy conversion system (WECS) is presented for the electrification of rural areas with availability. A three-phase AC-DC converter based on bridgeless Cuk used power extraction from permanent magnet synchronous generator (PMSG). The topology enables elimination front-end diode bridge rectifier (DBR). Moreover, has fewer components, simple control, and high efficiency, ma...

The efficiency of a short-term treatment with an intravaginal device containing progesterone (CIDR) combined with pregnant mares’ serum gonadotrophin (PMSG) and prostaglandin analogue (PGF2α) was evaluated for the induction of estrus, initiation of cyclic activity, and fertility in postpartum suckled yak cows. Seventy-five postpartum suckled yak cows were assigned to three treatments: (1) inser...

Superovulation in donors is an important factor influencing ovulation rate and embryo recovery. Crossbreed pubertal gilts (n=376) treated from year 2005 to 2009 were used as embryo donors. Experiment was evaluated in two parts: In the first part (I) gilts were divided into two groups with different synchronization schedules. In the first group (R+) 265 gilts were treated with Regumate Porcine (...
