Verification of insulation tests for traction motors
Electrical Engineering in Japan, 1997 More than 30,000 thousand dc motors are used by the Japan Railway group companies alone as traction motors for railway vehicles. Insulation breakdown of armatures is one of the most important problems in traction motors. Therefore, various insulation tests are carried out for each motor in overhaul. The methods for insulation tests were determined more

Neurovascular Contacts in the Pathophysiology of Neuralgic Amyotrophy: An Observational Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Neuralgic amyotrophy (NA) is a prevalent, monophasic, multifocal immune‐mediated neuropathy. A distinctive characteristic of the disease is the occurrence of nerve or fascicle constrictions and torsions (NA‐associated focal nerve lesions, NAFL). The pathophysiology underlying this phenomenon remains to be fully elucidated.

Advanced Engineering Materials, EarlyView.This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...
