MITIGATION OF ELECTRICAL DISCHARGE DAMAGE IN ELECTRIC VEHICLE BEARINGS: COMPARATIVE STUDY OF MULTI-WALLED CARBON NANOTUBES AND ALUMINA NANOPARTICLES IN LUBRICATING GREASE

The electrified environments encountered in electric vehicles (EVs) in terms of parasitic currents present significant challenges for the performance of EV bearings and their lubricants.This study investigates the effectiveness of various concentrations (0.1 wt.%, 0.2 wt.%, 0.3 wt.%, and 0.4 wt.%) of multi-walled carbon nanotubes (MWCNT) and alumin

The transition from the Cambrian to Ordovician in Morocco is known to be characterized by a frequent Furongian hiatus, restricted extension of the Tremadocian marine deposits, and frequent unconformities at the base of the transgressive upper Floian deposits.In telemarkskongen flue the present work, we first highlight the occurrence of Fe- and mica

Abstract We study the interior structure of five dimensional neutral helical black holes in Einstein gravity and charged helical black holes in Einstein-Maxwell gravity.Inside the neutral helical black holes, the systems evolve to a stable spacelike Kasner singularity.The metric field related to the helical deformation strength exhibits oscillation

A radioimmunoassay for the determination of 3 beta-hydroxy-5-cholenoic acid in human serum has been developed, using 3 beta-hydroxy-5-cholenoyl-thyroglobulin as immunogen and 3 beta-hydroxy-5-cholenoylglycyl-125I histamine as radioactive ligand.The association constant was 6.3 X 10(8) l/mol.Cross reactivity with other bile acids of human serum was

ABSTRACT Bats are well-recognized reservoirs of zoonotic viruses.Several spillover events from bats to humans have been reported, causing severe epidemic or endemic diseases including severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2), SARS-CoV, Middle East respiratory syndrome-CoV (MERS-CoV), henipaviruses, and filoviruses.In this study,
