The purpose of this study is to quantify the acute changes in endothelial histology that are associated with an induced increase in blood velocity. A nontraumatic intra-aortic device was designed to produce a rapid convergence of the aortic blood stream into a narrow channel along the ventral aspect of the thoracic aorta in dogs. The endothelial surface overlying this channel was exposed to a b...

Though still in use today, the method of the effective shearing force to evaluate the maximum shear stress in variable depth beams does not stand close scrutiny. It can lead to overestimating the shearing strength of these beams, although it is suggested as a viable procedure by many otherwise excellent codes of practice worldwide. This paper should help to put the record straight. It should wa...

In this study18 female sheep aged between 20-25 months was used in this experiment in alqasim city .the mow procedure was performed in a closed area using traditional method with shearers. The aim of study was to evaluate the stress response and the oxidant antioxidant balance against shearing process in sheep. Blood malonaldldhyde (MDA)and glutathione (GSH)concentration , were measured in 18 f...

-During the course of present investigation, effects of first order homogeneous chemical reaction and thermal radiation on two dimensional MHD flow of a visco-elastic fluid past a moving porous plate by considering double diffusive convection in presence of heat generation has been analyzed. A uniform magnetic field is applied in the direction normal to the moving plate. Also, the plate is cons...

We describe the effects of both magnetic buoyancy and differential rotation on a disc of isothermal gas embedded in a purely azimuthal magnetic field, in order to study the evolution and interplay of Parker and shearing instabilities. We perform a linear analysis of the evolution of perturbations in the shearing sheet model. Both instabilities occur on the slow MHD branch of the dispersion rela...
