Magnetic abrasive finishing can be classified as a non-traditional super finishing method for finishing surfaces with different shapes and working materials like flat plates, shafts, bearings parts, screws, tubes and many other mechanical parts that need good surface finishing properties. MAF is effective in polishing, cleaning, deburring and burnishing metal parts. The most important parameter...

analytical chemistry has experienced, as well as other areas of science, a big change due to the needs and opportunities provided by analytical nanoscience and nanotechnology. now, nanotechnology is increasingly proving to be a powerful ally of analytical chemistry to achieve its objectives, and to simplify analytical processes. moreover, the information needs arising from the growing nanotechn...

In this study the effect of magnetic Reynolds number variation on magnetic distribution of natural convection heat transfer in an enclosure is numerically investigated. The geometry is a two dimensional enclosure which the left wall is hot, the right wall is cold and the top and bottom walls are adiabatic. Fluid is molten sodium with Pr=0.01 and natural convection heat transfer for Rayleigh num...

in order to study the effects of magnetic field, silver nano particles and micronutrient fertilizers on sugar beet, an experiment was conducted at razavi research and technology institute, mashhad, iran. experiment carried out with seven treatments based on randomized complete block design with three replications. treatments included (t1) magnetic field and silver nano particles + kemira fertil...

Agar/Fe3O4 nanocomposites were synthesized in the presence of an external magnetic field (~ 0.4 Tesla) and their characteristics were compared with the samples synthesized without considering the external magnetic field. In this study we used Fe2+ and Fe3+ for synthesizing Fe3O4 magnetic nanoparticles in the presence of agar as polymeric additive, by co-precipitation technique. Vibrating sample...

In this study, the authors reported a case of woman with severe compulsion who became pregnant during the Repetitive transcranial magnetic stimulation. We carried out Repetitive transcranial magnetic stimulation and behavior therapy simultaneously after repeated medications' refraction. The patient received 20 sessions 1 Hz Repetitive transcranial magnetic stimulation in right dorsolateral pref...

hard magnetic srfe12o19 (srm) nanoparticles were synthesized by a facile sonochemical reaction. the magnetic nanoparticles were then added to acrylonitrile-butadiene-styrene, polystyrene, polycarbonate, and poly sulfone to make magnetic nanocomposites. the magnetic properties of the samples were also investigated using an alternating gradient force magnetometer. the strontium ferrite nanopartic...

in this study, the feasibility of using magnetic technology to reduce the dispersion of soil has been investigated. the reference treatment was potable water and 3 magnetic water devices (with different magnetic intensities) were used for magnetizing the potable water. the results showed that the magnetic field has a significant effect in order of 5 percent on increasing of magnesium concentrat...
