We have shown previously that mRNA for peroxisome proliferator-activated receptor gamma (PPARgamma) is expressed in granulosa cells and downregulated by the luteinizing hormone (LH) surge. The current studies were undertaken to test the hypothesis that LH stimulates a decrease in the expression of PPARgamma, as well as its activity, in granulosa cells. Ovaries were collected from immature rats ...

This research was conducted to study the follicular dynamics, hormonal, biochemical profile and fertility response in acyclic and norgestomet+PMSG treated acyclic buffaloes in summer. The study animals were divided into two groups: group I [control (n=8): no treatment] and II [treatment group (n=15)]. In group II, seven animals were used for follicular biochemical and hormonal profile and eight...

Glucocorticoids are known to have diverse effects on the uterus, generally believed to be mediated by the glucocorticoid receptor (GR). To date, two isoforms of the enzyme 11beta-hydroxysteroid dehydrogenase (11betaHSD) have been identified, namely 11betaHSD1 and 11betaHSD2, which interconvert active and inactive glucocorticoids and regulate local levels of hormones available to the GR in targe...

ABSTRAKPerubahan laju aliran air pada pembangkit listrik pikohidro dapat menyebabkan daya dan tegangan yang dihasilkan generator menjadi tidak stabil. Penelitian ini bertujuan untuk merancang Maximum Power Point Tracking (MPPT) dengan algoritma logika fuzzy Permanent Magnet Synchronous Generator (PMSG) penstabil aplikasi pikohidro. Pada penelitian digunakan dua unit konverter DC/DC tipe buck-bo...

This study proposes a product sustainability assessment tool (PSAT) that addresses the environmental, health and safety, social, economic aspects from life cycle perspective. The proposed PSAT uses principles of Green Chemistry, Industrial Ecology, Engineering as guidelines in development its criteria. developed criteria are expressed easy-to-answer questions covering safety sustainability. als...

in recent years, there has been a fast growth in wind energy conversion system (wecs). there are two general types of wind turbines in wecs: fixed speed wind turbines and varying speed wind turbines.permanent magnet synchronous generator (pmsg) is one of the most attractive generators for the varying speed turbine wecs.in this paper, a fuzzy controller is proposed to control the current source ...

objective: the aim of the present study was to evaluate artificial insemination techniques on reproductive performance in ghezel ewes synchronized with cidr during breeding season. methods: all ewes were treated with controlled internal drug release device (cidr) inserted into the vagina of the ewes for 14 days. all ewes were treated a single intramuscular (im) dose of pmsg was injected. in thi...

In this paper, the design and implementation of a permanent magnet synchronous generator (PMSG) based wind energy conversion system battery bank storages are connected to utility grid. It has phase locked loop (PLL) control strategy as it provides for single-phase grid inverter with constant dc-link voltage. The is interfaced through diode bridge rectifier (DBR) dc-dc boost converter, single vo...

Wind power plants (WPPs) are required to provide primary frequency regulation services when a high proportion of wind is connected the grid. The reserve turbine generators (WTGs), including rotor kinetic energy and deloading power, determined by its current speed active thus, different levels WTGs will be formed because variable wake effect in WPP. This article proposes an adaptive control stra...
