Present study was designed to evaluate the semen quality of breeding bulls positive for 24 and 30 kDa heparin binding proteins (HBPs) in the semen.Seventeen Holstein Friesian breeding bulls were screened for 24 and 30 kDa HBPs in semen by heparin-sepharose affinity chromatography and SDS-PAGE, and grouped into three based on presence/absence of HBP
The interest in motor drive systems with a number of phases greater than three has increased, mainly in high-power industrial fields due to their advantages compared with three-phase drive alesis vi61 systems.In this paper, comprehensive mathematical modeling of a five-phase matrix converter (MC) is introduced.Besides that, the direct and indirect
Proton exchange membrane fuel cells are a new energy technology with great potential due to advantages such as high efficiency and no pollution.The structure of the gas flow channels has a profound impact on the overall performance of the fuel cell.Different flow channel geometries barbie jogadora de v?lei have their own advantages and disadvantage
This paper provides an application of the hybrid Grey Wolf Optimization and Particle Swarm Optimization (GWO-PSO) method to reach a solution to the optimal reactive power dispatch (ORPD) problem in the scope of electric power networks.PSO is a swarm based meta-heuristic optimization algorithm whose target is to seek the best solution to a problem b
