Male fertility requires the continuous production of high quality motile spermatozoa in abundance. Alterations in all three metrics cause oligoasthenoteratozoospermia, the leading cause of human sub/infertility. Post-mitotic spermatogenesis inclusive of several meiotic stages and spermiogenesis (terminal spermatozoa differentiation) are transcriptionally inert, indicating the potential importan...

The influence of the different properties gas diffusion layer (GDL) on operation a liquid-cooled, proton-exchange polymer electrolyte fuel cell (PEMFC) has been studied in this work. Three-dimensional numerical simulations (CFD) have conducted to compare several commercial GDLs with properties, analyzing their performance. Specifically, four (AvCarb P-75, SIGRACET 34BC, 34BA and Toray TGP-H-090...
