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...
Free convection flow in an enclosure filled with a congealing melt leads to the product with a nonuniform structure involving large grains. The convective flows are decreased by applying an appropriate magnetic field, obtaining uniform and small grain structures. In this work, using the finite volume method, we investigated the application of a magnetic field to the convective heat transfer and...
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...
In the present paper, we have studied MHD free convective two dimensional unsteady viscous incompressible flows through a porous effect bounded by an infinite vertical porous plate with constant suction. The permeability of the porous medium fluctuates in time about a constant mean, and the viscosity of fluid is assumed to vary as a linear function of temperature. The flow is permitted under th...
Background: Ischemic stroke is a common cause of adult disability and death worldwide that leads to damage in neuronal networks and neurovascular units and ceasation of brain functions. In this study the effect of iron oxide nanoparticles and magnetic field on neurogenesis after ischemic reperfusion (IR) in rat model was evaluated. Methods: In this experimental study 50 male Wistar rats weighi...
Abstract: In chloride salt solutions, titanium alloys exhibit reasonably high pitting potentials as high as +10 V (vs. Ag/AgCl) at room temperatures. On the other hand, anodic pitting potentials are significantly lower in bromide solutions. In this study, pitting corrosion of commercially pure titanium in aqueous NaBr solution of 0.1 M concentration at room temperature was studied and the e...
The effect of magnetic field on torsional waves propagating in non-homogeneous viscoelastic cylindrically aeolotropic material is discussed. The elastic constants and non-homogeneity in viscoelastic medium in terms of density and elastic constant is taken. The frequency equations have been derived in the form of a determinant involving Bessel functions. Dispersion equation in each case has been...
Background & Aim: In human environment, magnetic fields are created by electrical generators, power lines, and electrical instruments. These fields could affect learning and memory. This study was planned to evaluate whether short time exposure to magnetic fields has any significant effect on spatial memory. Material & Method: In this experimental study, we used 10 male Albino Wistar mice ...
During the past decade considerable evidence has been accumulated with regard to the biological effects, both in vivo and in vitro, of extremely low frequency electric and magnetic fields, such as those originating from residentially proximate power lines, household electrical wiring and diagnostic apparatus and therapy devices. Also, during the evolution process, all living organisms experienc...
