Volumetric integral and integro-differential equations are considered that describe problems of diffraction by three-dimensional bodies with given macroscopic permittivity magnetic permeability, as well on free vibrations such bodies. Similar obtained for waveguide structures: hollow shielded waveguides dielectric filling, (optical beamguides), photonic-crystal waveguides. Dominantly stationary...

effects of hall current, ion-slip and coriolis force on unsteady mhd couette-hartmann flow of a viscous incompressible electrically conducting fluid through a porous medium bounded by porous plates in the presence of a uniform transverse magnetic field which is either fixed relative to the fluid or to the moving porous plate is investigated using laplace transform technique. the expressions for...

In the present paper behavior of free convective boundary layer flow an electrically con-ducting visco-elastic,incompressible fluid through a porous medium over continuously moving surface in presence uniform magnetic field with constant suction is studied. A assumed to be applied perpendicularly surface. similarity transformation used which reduces partial differential equation ordinary equati...

This article is intended to provide clinical neurologists with an overview of the major techniques of advanced MRI of brain tumor: diffusion-weighted imaging, perfusion-weighted imaging, dynamic contrast-enhanced T1 permeability imaging, diffusion-tensor imaging, and magnetic resonance spectroscopy. These techniques represent a significant addition to conventional anatomic MRI T2-weighted image...

The magnetic permeabiility and the thickness of the socalled %on"magnetic grain boundary were studied for a MgMnZn-femte with composition M~,J~,&ln,lFe,,,03,m For the mono-domain situation the grain size dependence of the effective initial permeability is well described by the nonmagnetic grain boundary model. A gradual increase of permeability with grain size around the transition from monoto ...

This report evaluates a variety of dental materials with respect to MR imaging artifacts and their mechanisms of production. A 0.15-T superconducting system and an MR phantom were used in assessing imaging artifacts. Several in-vivo studies were also carried out. The dental materials were analyzed for composition and magnetic permeability and the results were compared with the artifacts produce...

Epoxy matrix nanocomposites with nickel nanoparticles of two different sizes were processed and characterized to investigate their structure-magnetic property correlations. Crystal structure, morphology, density, resistivity and magnetic properties of the nanocomposites with different filler contentswere compared for different size scales. Nanocomposites with 25 nm nanoparticles showed higher c...

Magnetohydrodynamic(MHD) peristaltic flow of a Couple Stress Fluid through a permeable channel is examined in this investigation. The flow analysis is performed in the presence of an External Magnetic Field. Long wavelength and low Reynolds number approach is implemented. Mathematical expressions of axial velocity, pressure gradient and volume flow rate are obtained. Pressure rise, frictional f...
