This study compares the film thickness, lubricant temperature, and traction curves of two groups commonly used constitutive models for lubricants in thermo-elastohydrodynamic lubrication (TEHL) modelling. The first group consists Tait equation state, Doolittle Newtonian viscosity model, Carreau shear thinning model. second includes Dowson Roelands–Houpert Eyring simulations were conducted using...

Articular cartilage is a robust tissue that facilitates load distribution and wear-free articulation in diarthrodial joints. These biomechanical capabilities are fundamentally tied to hydration, whereby high interstitial fluid pressures support facilitate maintenance of low strains frictions. Our recent ex vivo studies sliding biomechanics using the convergent stationary contact area (cSCA) con...

Multiple forms of hydrolytic enzymes were demonstrated in extracts of healthy bean leaves (Phascolus vulgaris L.) and bean leaves infected with the halo blight organism [Pseudomonas phaseolicola (Burkh.) Dowson] by polyacrylamide disc electrophoresis. Bean leaves contained up to 4 acid phosphatase bands, 9 esterase bands active towards alpha-naphthyl acetate, and 7 esterase bands towards alpha-...

Many attempts have been made during the past 20 years to explain the remarkable lubricating qualities of synovial fluid (Dowson, 1966-67; McCutcheon, 1966-7) but, until recently, relatively little attention has been paid to the precise threedimensional form of the articulating surfaces between which the fluid is interposed. Indeed, McCall (1968) stated that the literature contained no light mic...
