RE: Random vs. Form-wound stator coils for IFDs. Simply buy a motor that is rated for the service it is to perform. In North America, that would be a motor with an MG1 Part 31 endorsement on the nameplate. I'm not familiar with similar endorsements in the IEC world but there may well be one or more.
5a-Reductase (5AR) is the enzyme that catalyzes the conversion of (among others): 1  Testosterone â 5a-DHT. 2  Androstenedioneâ androsterone. 3  Cortisol â allo-tetrahydrocortisol.s early as 1986, it was suspected by some that 5a-DHT might be a primary contributing factor to prostate cancer growth. 15 5a-Reductase (5AR) is responsible for conversion of testosterone to 5a-dihydrotestosterone (5a-DHT).
LPAR. (L ogical PAR tition) A logical segmentation of a mainframe's memory and other resources that allows it to run its own copy of the operating system and associated applications.LPARs are caused by special hardware circuits and allow multiple system images to run in one machine.DF was the first to provide in hardware the equivalent of IBM's VM operating system, which supports multiple system images in software. Interestingly, an LPAR can host VM, which itself can host multiple operating systems. See PR/SM and virtual machine.
