This study investigates the read more contribution of magnetostriction to vibration and acoustic noise in interior permanent magnet synchronous motors using finite element analysis and experiments on two test machines.The two motors have identical dimensions but different iron core materials.The first motor is made of 6.5% high-silicon steel
Abstract Background There is scientific evidence that preventive physical exercise is effective even in high age.In contrast, there are few opportunities of preventive exercise for highly aged people endangered by or actually in need of care.For example, they would not be able to easily go to training facilities; standard exercises may be too inten
Biogenic amines (BAs) and free amino acids (AAs) are low-molecular nitrogenous compounds occurring in a wide range of foodstuffs, found in increased amount in different fermented foods, seafood, and wines.This study deals with the development of an analytical method based on liquid chromatography with tandem mass spectrometry with precolumn derivat
LuTan-1 (LT-1) cga 200 to cga 510 adapter is a constellation with two full-polarization L-band radar satellites designed by China, and the first satellite was scheduled to be launched in December 2021 and the second one in January 2022.The LT-1 will be operated for deformation monitoring in repeat-pass mode, and for DEM generation in bistatic mode,
