The effect of inhomogeneous static magnetic field (SMF) on visceral pain elicited by the intraperitoneal injection of 0.6% acetic acid (writhing test) was studied in mice in an environment, where animals could freely move. 30 min, whole-body exposure of mice to SMF (permanent NdFeB N50 grade 10× 10mm cylindrical magnets with alternating poles) following the nociceptive challenge resulted in a 7...
This paper proposes a novel dual-consequent-pole Vernier memory machine (DCP-VMM) featuring alternatively arranged NdFeB and low coercive-force (LCF) magnet poles on the rotating and stationary sides, respectively. Due to the presence of LCF magnets that can be repetitively magnetized or demagnetized via a simple current pulse, the extra-high torque density at low-speed, and excellent high-effi...
The surface condition and microstructure of near stoichiometric (Fe823Ndll.8B5.9) Nd-Fe-B alloy ribbons and the effect of melt spinning parameters were investigated using optical, scanning and transmission electron microscopes (SEM, TEM). The formation of gas pockets on the roll surface of the ribbons during melt spinning can prevent heat transform and result in local coarse grains. The local t...
