The flocculated structure and flow properties of suspensions of brilliant carmine 6B (C6B) in polybutadiene were investigated. In this study, we have used simple suspensions of C6B in polybutadiene having different viscosity. Stress overshoot phenomenon after various rest periods and double-step shearing test were examined for the suspensions. In the double-step shearing test, a transient stres...

Shearing ewes in mid pregnancy can provide farmers with management and financial advantages. Six experiments conducted at Massey University have collectively shown that shearing ewes at this time can increase lamb birthweight by up to 1.0 kg. When comparisons were made across studies, there was a strong negative relationship between size of the response and the birthweight of control lambs (tho...

Cropping is a cutting process whereby opposing aligned blades create a shearing failure by exerting opposing forces normal to the surfaces of a metal sheet or plate. Building on recent efforts to quantify cropping, this paper formulates a plane strain elastic–plastic model of a plate subject to shearing action by opposing rigid platens. Shear failure at the local level is modeled by a cohesive ...

Gravitational instability of a vertically thin, dusty sheet near the midplane of a protoplanetary disk has long been proposed as a way of forming planetesimals. Before Roche densities can be achieved, however, the dust-rich layer, sandwiched from above and below by more slowly rotating dust-poor gas, threatens to overturn and mix by the Kelvin-Helmholtz instability (KHI). Whether such a threat ...

A general analysis and experimental validation of transmission wavefront shearing interferometry for photoelastic materials are presented. These interferometers applied to optically isotropic materials produce a single interference pattern related to one phase term, but when applied to photoelastic materials, they produce the sum of two different interference patterns with phase terms that are ...

We report a simple method that uses (i) emulsion shearing with oxidation to make core-shell particles, and (ii) emulsion shearing with surface-tension driven phase segregation to synthesize particles with complex surface compositions and morphologies. Subjecting eutectic gallium-indium, a liquid metal, to shear in an acidic carrier fluid we synthesized smooth liquid core-shell particles 6.4 nm ...

We give an analysis of the stability and uniqueness of the simply laminated microstructure for all three tetragonal to monoclinic martensitic transformations. The energy density for tetragonal to monoclinic transformations has four rotationally invariant wells since the transformation has four variants. One of these tetragonal to monoclinic martensitic transformations corresponds to the shearin...

forty sheep skins were allocated into two groups. group one was sheared using shearing machine and group two was chemically dewooled using 15 percent sodium sulfide. results indicated that fibre diameter of slipewool (39.3 ± 2.3 µm) was significantly (p< 0.05) higher than the sheared wool fibers (36.3 ± 0.7 µm), but staple length of slipewool (3.3 ± 0.7 cm) was significantly (p< 0.05) lower tha...

regions on three ovine chromosomes (oar1, oar5 and oar25) were selected to study quantitative trait loci (qtl) segregating for wool traits in baluchi sheep. a total of 503 progeny from 13 half-sib families were genotyped for 15 microsatellite markers. the average number of progeny per sire was 38 and ranged between 16 and 59. data were collected from research centre on baluchi breed in 2009 and...
