In Nuclear Magnetic Resonance (NMR) experiments, besides the apparatus designed to acquire the NMR signal, it is necessary to generate a radio frequency electromagnetic field using a device capable to transduce electromagnetic power into a transverse magnetic field. We must generate this transverse homogeneous magnetic field inside the region of interest with minimum power consumption. Many con...

although the promotional effects on bone healing of pulsed electromagnetic fields (pemf) have beenwell demonstrated, the effects of static magnetic fields (smf) remained unclear. in this study, effects of acustom-made magnetic wrap on radiographic and histopathological aspects of bone healing using a canineunstable osteotomy gap model were investigated. after an osteotomy of the midshaft radius...

Plants are generally subjected to a combination of different conditions such as magnetic field and soil bacteria in their life. The present investigation tried to compare the effects and interactions of magnetic field and rhizobial inoculant in alfalfa. A pot experiment was performed under a natural condition by a factorial design to ...

Context. Massive hot stars produce dense ultraviolet (UV) photon fields in their surroundings. If a very high-energy (VHE) gammaray emitter is located close to the star, then gamma-rays are absorbed in the stellar photon field, creating secondary (electron-positron) pairs. Aims. We study the broadband emission of these secondary pairs in the stellar photon and magnetic fields. Methods. Under ce...

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 this research, some more applicable ferrofluids are produced and their mechanical specifications are measured, experimentally. also, their treatments in the ventilated cavity geometry are assessed numerically. the magnetite nanoparticles are produced by a chemical combination of fe2+ and fe3+ with nh3. in order to solve the nanoparticles in the new mediums, a proper coating is added to them....

The effect of a transverse magnetic field on the boundary layer flow and heat transfer of anisothermal stretching cylinder is analyzed. The governing partial differential equations for themagnetohydrodynamic, temperature, and concentration boundary layers are transformed into a setof ordinary differential equations using similarity transformations. The obtained ordinarydifferential equations ar...

----------------------------------------------------ABSTRACT-----------------------------------------------------In the present paper is an investigation of heat and mass transfer characteristics of MHD free convection of steady flow of an incompressible electrically conducting fluid over an inclined plate under the influence of an applied uniform magnetic field and the effects of Hall current ...
