Micro-pitting is a common fatigue failure Collagen mode of spur gears.To reduce it, this paper proposes a novel tooth tip relief method.Gear meshing simulation is firstly performed considering the actual contact path, showing that there are four Hertz contact stress peaks in the transition areas of the tooth flank.Equations are then developed for t
Over the last quarter century, more than 532 genes have been put forward as regulatory targets of retinoic acid.In some cases this Collagen control is direct, driven by a liganded heterodimer of retinoid receptors bound to a DNA response element; in others, it is indirect, reflecting the actions of intermediate transcription factors, non-classical
Car Chargers This paper investigates the combined effect of radial magnetic field and viscous dissipation on entropy generation in horizontal co-axial cylinders of generalized Couette flow.The analytical solutions for velocity and temperature profiles are obtained and utilized to compute the entropy generation, Bejan number as well as the average e
The risk of developing pulmonary hypertension (PH) in people living with HIV is at least 300-fold higher than in the general population, and illicit drug use further potentiates the development of HIV-associated PH.The relevance of extracellular vesicles (EVs) containing both coding as well as non-coding RNAs in PH secondary to HIV infection and dr
