Mechanical shearing of crystals of a polymorph with a layered structure may be used to separate them from harder crystals of a visually indistinguishable polymorph that resist such shearing.

The relative mean square error in the three-dimensional stress field predicted by classical plate theory is shown to be OQi/L^)2, where h is the plate thickness and Lj. is a mean square measure of the wavelength of the midplane deformation pattern. This improves a recent result of Nordgren who obtained a relative error estimate of 0(h/L*). The improved error estimate, which, like Nordgren's, is...

The effect of an axially symmetric mild stenosis on the steady flow of blood, when blood is represented by Newtonian model have been studied. Theoretical results for the velocity profile, pressure gradient, wall shearing stress and separation phenomena are obtained by solving the momentum integral equation. The results obtained are discussed graphically for mild stenosis for Reynolds number (Re...

This paper is a continuation of two recent publications on crack growth in viscoelastic media. It provides further theoretical results for large strains that enable prediction opening displacement comparison with experimental data the region singularity. In order to achieve good agreement experiment it was necessary account far-field viscoelasticity. Additionally, found deformation throughout s...

Abstract The rheological properties of cement pastes prepared using kenaf-plant cellulose microfibers (CMFs), which was incorporated for the purpose internal curing, were investigated. main test variables are length and mass fraction CMFs. CMFs lengths 400 ?m 5 mm included in mixtures at 0.3, 0.6, 1, 2 wt.% cement. Dry CMF particles wetted with water to fiber saturation point vacuum filtration ...
