We previously reported that the intraperitoneal and intrabursal administration of bestatin, an aminopeptidase inhibitor, enhanced follicular growth and ovulation in immature mice. In this study, we examined the effect of bestatin on follicular growth and ovulation under the conditions in which the ovarian response to gonadotropins was suppressed. Immature female mice were exposed to 72-h contin...

Ewes were treated with a medroxyprogesterone acetate (MAP) sponge for 8 d followed, at sponge removal, with 500 IU pregnant mare serum gonadotropin (PMSG) at d 30, 40 or 50 (d 0 = lambing) to induce estrus. Dry and lactating ewes were divided into equal numbers at each postpartum day and bred at estrus. Conception rates and number of accessory sperm were determined by flushing the oviducts 3 d ...

In this paper, we focused on modeling and simulation of a hybrid solar-wind energy system, consisting photovoltaic cell wind turbine driven by Permanent Magnet Synchronous Generator (PMSG). The proposed system gives details the system. PV subsystem, there will be MPPT controller, DC-DC boost converter. subsystem includes PMSG, controller. controllers were designed to extract maximum power regar...

Generator dapat menghasilkan listrik dengan tiga syarat, yakni : terdapat medan magnet, coil dan adanya perubahan flux yang melewati coil. Tempat untuk meletakkan pada generator disebut slot, jumlah slot berpengaruh karakteristik generator. Perubahan Back EMF KE. Simulasi menggunakan kawat lilitan diameter 1 mm. Pada penelitian ini dilakukan perancangan PMSG 12s10p, divariasikan slotnya menjadi...

Due to the complexity of detailed models, single-generator equivalent model (SEM) a wind farm is commonly used facilitate stability analysis. However, adequacy SEM for analysis in direct-drive farms with VSC-HVDC systems still uncertain. Therefore, this article analyzes two aspects: oscillation modes and sub-synchronous (SSO) enhancement by optimizing parameters. Firstly, various critical are c...

Higher efficiency, predictability, and high-power density are the main advantages of a permanent magnet synchronous generator (PMSG)-based hydro turbine. However, control PMSG is nontrivial issue, because its time-varying parameters nonlinear dynamics. This paper suggests novel optimal fuzzy supervisor passivity-based high order sliding-mode controller to address problems faced by conventional ...

Wind power is one of the most promising renewable energy sources. Due to a constantly increasing penetration rate in grids order comply with interconnection requirements. This article targets impact permanent magnet synchronous generator (PMSG) which subject attention due low cost and maintenance requirements, driven by wind turbine necessary electronic converters that allow turbines operate at...

Permanent magnet synchronous generator (PMSG) wind power system with full rating converter configuration is especially suitable for energy applications. Direct model predictive control (DMPC) has led to more possibilities in terms of choice because its straightforward concept PMSG turbine systems high-power off-shore farms. However, due complete dependence on the knowledge, parameter mismatches...
