introduction increase in alpha band is observed when blood perfusion in frontal area of head decreases. the present study evaluated some changes in the alpha band particularly, alpha-1 of frontal and central areas of the head, when several areas were exposed simultaneously to magnetic field. materials and methods five points of head (f3, f4, cz, t3, and t4) of twenty healthy male participants w...

this study is considering a micropolar fluid flow over a porous stretching sheet in the presence of thermal radiation and uniform magnetic field. the effects of local variation in thermal conductivity of micropolar fluid on heat transfer rate from the sheet are investigated; besides, the impacts of radiation, magnetic field and porous sheet on variations of thermal boundary layer thickness are ...

background : electromagnetic fields are associated with production, transmission and use of electricity. in this  tudy we have investigated the effects of short and long time alternative magnetic fields' (amf, 50 hz) exposure on the secretion of hypothalamic-pituitary-gonadal axis in the male rats. methods : forty eight wistar male rats, same range of age and weight were divided into four group...

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...

Abstract We study the transition of short range Ising spin glasses in a magnetic field, within a general replica symmetric field theory, which contains three masses and eight cubic couplings, that is defined in terms of the fields representing the replicon, anomalous and longitudinal modes. We discuss the symmetry of the theory in the limit of replica number n → 0, and consider the regular case...

Magnetic-field dependence of the resistivities in MnAs 1100 films on GaAs 001 and MnAs 0001 films on GaAs 111 B is investigated at low temperatures. Correspondence of the features in the longitudinal and transverse resistivities under reorientations of the magnetization enables us to distinguish the anisotropic magnetoresistance effect from the effects originating from the band structure of MnA...

We have recently obtained new explicit nonperiodic solutions for the three-dimensional timedependent wave equation in spherical coordinates. Since Maxwell field equation (MFE) is formed by four wave equations, our results also lead to nonperiodic solutions of the set of classical Maxwell’s equations (ME). To understand the meaning of these new expressions, we revisited the standard derivation o...

A model-free theoretical framework for a phenomenological description of spin-lattice relaxation by anomalous translational diffusion in inhomogeneous systems based on the fractional diffusion equation is developed. The dependence of the spin-lattice relaxation time on the size of the pores in porous glass Vycor is experimentally obtained and found to agree well with our theoretical predictions...

The interaction of conduction electrons with a longitudinal sound wave propagating in a crystal in a constant magnetic field is investigated. It is shown that the transverse spin current arises when the longitudinal sound wave propagation through the system. The average power absorbed by the spin subsystem of the conduction electrons and the spin-Hall conductivity have a resonant character.

the use of magnetic fields in targeted drug delivery, especially for treatment of cancers and tumoral regions, is one of the significant techniques in the field of modern methods of treatment. considering that many vital biological tissues have been located deep in the body, then for targeted drug delivery and effective treatment in these tissues, it is required to bring therapeutic agent to th...
