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).
Two 5-alpha-reductase (5aR) iso-enzymes have been identified: type 1 5-alpha-reductase, and type 2 5-alpha-reductase.Type 1 5aR has been found in various parts of the body including sebaceous glands, the epidermis, sweat glands, nervous system cells and in hair follicles (dermal papilla, outer root sheath, and matrix).In skin, type 1 5aR activity is primarily concentrated in sebaceous glands of the face and scalp.ype 1 5aR has been found in various parts of the body including sebaceous glands, the epidermis, sweat glands, nervous system cells and in hair follicles (dermal papilla, outer root sheath, and matrix).
