Nitric oxide (NO) has emerged as a novel regulator of several ovarian events, such as ovulation, steroidogenesis, and apoptotic cell death. The NO synthases (NOS) are a family of enzymes that catalyze the oxidation of L-arginine to NO and L-citrulline. The purpose of the present study was to localize NOS isoforms in the rat ovary and to examine their hormonal regulation. We conducted immunohist...

In this paper, a model of a variable speed wind turbine using a permanent magnet synchronous generator (PMSG) is presented and the control schemes are proposed. The model presents the aerodynamic part of the wind turbine, the mechanic and the electric parts. Simulations have been conducted with Matlab/Simulink to validate the model and the proposed control schemes.

In this paper, a comparative analysis of Total Harmonic Distortion (THD) between wind farms with double-fed induction generators (DFIG) and synchronous permanent magnet (PMSG) integrated into the grid is developed. The Fast Fourier Transform (FFT) technique to evaluate output current signal THD in different fault conditions indicate best performance among used. generation problems are associate...

In this paper, a standalone permanent magnet synchronous generator (PMSG) system is designed to generate power at maximum point (MPP). The variable speed operation of wind energy conversion consists PMSG, controlled rectifier and voltage source inverter co the load. Proportional integral (PI), sliding mode (SM), feed forward neural network (FFNN) control strategies are applied in field oriented...

The use of Universal type motors is very commonly used, both in daily life and research activities. universal motor can be used as prime mover generator PMSG (Permanent Magnet Synchronous Generator), which its application there are obstacles, namely the difficulty stabilizing speed due to influence changes load connected PMSG, this affects output voltage generated by system. In case, a stabiliz...

PPARs are a family of nuclear hormone receptors involved in various processes that could influence ovarian function. We investigated the cellular localization and expression of PPARs during follicular development in ovarian tissue collected from rats 0, 6, 12, 24, and 48 h post-PMSG. A second group of animals received human CG (hCG) 48 h post-PMSG. Their ovaries were removed 0, 4, 8, 12, and 24...

us damages to the ovary storage and the matrix muscle state. some of these patients may admit to infertility clinics for having pregnancy and on the other hand hormonal administration for superovulation induction is a routine procedure in assisted reproduction technology (art) clinics.objective: this study aimed to investigate fertility and fetuses of hormone treated super ovulated female mice ...

Presently, among the global ocean energy technologies, most conventional one is wave power generation device based on oscillating water column (OWC) converter. Given fluctuation and randomness of waves complexity current grid, dynamic response grid connections must be considered. Furthermore, considering characteristics converter, this paper proposed an adaptive intelligent controller (AIC) for...
