The mechanisms of pedestrian slip on flooring contaminated with solid particles [PDF]
Statistics by the UK Health and Safety Executive (HSE) suggest that slips, trips and falls account for up to one in three major workplace accidents. The vast majority of these accidents are the result of contaminant (fluid or solid) within the shoe-floor

Assessment of Friction Losses and Friction Factor in Polypropylene Pipes
Recently, polypropylene (PPR) pipes have been increasingly used to replace galvanized iron pipes in most water transmission systems due to their ease of installation and perceived health safety. Also, PPR has engineering features that do not deteriorate

Effect of organic acid concentration in lubricant on tribological characteristics of friction couple
Introduction. The possibility of using monocarboxylic acids as a lubricant composition additive, and the effect of their concentration in lubricant on the evolution of the friction factor of a brass-steel couple, as well as the morphology of the film ...

Measurement of Local Convective Heat Transfer Coefficient of Alumina-Water Nanofluids in a Double Tube Heat Exchanger [PDF]
Heat transfer coefficient and thermal efficiency of γ-Al2O3/water nanofluids flowing through a double tube heat exchanger were experimentally investigated. The nanoparticles were well dispersed in distilled water at 0.05–0.15 %vol.

Relativistic Dynamical Friction in the Weak Scattering Limit
A test mass, $M$, moving through an ambient medium of light particles with lower average kinetic energy than itself suffers a deceleration caused by its scattering of the light particles. The phenomenon is usually referred to as dynamical friction.
