Traction characteristics of polymer blended oils.
Journal of The Japan Petroleum Institute, 1987 In order to develop polymer additives which increase the traction coefficient of its blended oils, many kinds of homopolymers and copolymers were synthesized. The traction coefficient of polymerblended oils was measured with a two-disk machine. The relation between traction coefficient of the blended oils and molecular structure of the polymer ...

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.
