The estrous cycle influence on the number of ovulated eggs after injection of pregnant mare serum gonadotropin (PMSG) and human chorionic gonadotropin (hCG) was investigated in 12, 18, and 24 weeks old adult female Wistar-Imamichi (WI) rats. PMSG (150 IU/kg) was injected at metestrus, diestrus, proestrus, or estrus, followed by hCG (75 IU/kg) 55 h later. Ovulation was induced at all ages and st...

To optimize the output power and reduce the frequency fluctuation in conventional fixed speed Induction Generator (IG) based wind farm, various controlling devices are used. But, this paper proposes that Permanent Magnet Synchronous Generator (PMSG) can work both as a power producing device and as a controlling device for IG. In this paper a more practical case has been considered where a wind ...

Gonadotropic hormones PMSG (15 IU/rat), FSH (3 micrograms/rat), LH (9 micrograms/rat) and hCG (3 micrograms/rat) were shown to decrease the free cytosolic lysosomal enzymes during the acute phase of hormone action in rat ovaries. When isolated cells from such rats were analyzed for the cathepsin-D activity, the granulosa cells of the ovary showed a reduction in the free as well as in the total ...

Different types of permanent magnet generators for wind power application have been subject of research during last two decades. In this thesis different topologies of electrical generators have been investigated for small scale vertical axis wind turbine application. A two stage induction generator is proposed as a alternative solution with respect to the cost of such a system. However, a bigg...

Peptide mass-signature genotyping (PMSG) is a scanning genotyping method that identifies mutations and polymorphisms by translating the sequence of interest in more than one reading frame and measuring the masses of the resulting peptides by mass spectrometry. PMSG was applied to the RDS/peripherin gene of 16 individuals from a family exhibiting autosomal dominant macular degeneration. The meth...

The increasing demand of electric power necessitates the establishment of new generating stations. Wind energy conversion system (WECS) is more attractive due to its mature and clean aspects. During last decades the variable speed wind turbine concept has been increasingly receiving attention due to the fact that it is more controllable and efficient, and has good power quality. The wind turbin...

The aim of this study was to exam sexual receptivity in rabbit does at the day of artificial insemination using the colour of vulva, rectal temperature and vagina cytology by the percentage of keratinized cells. A total of 36 multiparous INAT does were used for this purpose and they were injected with PMSG before artificial insemination (AI). 48 hours after injection, does detected receptive, w...

Permanent magnet generators for renewable energy application have been subject of research during last two decades. Several kinds of rotating electrical generators exist for several applications, including synchronous, induction and DC machines. Doubly Fed Induction Generator is proposed as an alternative solution with respect to the cost of such a system. However, a bigger emphasis in the repo...

Grid-connected wind turbines are fluctuating power sources that may produce flicker during continuous operation. This paper presents a simulation model of a MW-level variable speed wind turbine with a full-scale back-to-back power converter and permanent magnet synchronous generator (PMSG) developed in the simulation tool of PSCAD/EMTDC. Flicker emission of this system is investigated. The 3p (...
