The problem of unbounded uniaxial chiral omega media in the presence of both static electric and magnetic point charges is investigated. For this purpose scalar electric and magnetic potentials in these media are introduced. Using these potentials, the corresponding electric and magnetic fields are determined. The similar problem of static electric and magnetic current sources with the goal of ...

introduction: biological effects of magnetic fields have been investigated by scientists for many years and a vast amount of research using different frequencies and intensities have been performed on humans and laboratory animals. the results of these studies, which have mostly been done by applying high frequencies, have shown that electromagnetic fields are effective on structure and functio...

the second somatosensory area (sli) has been studied both by electrical evoked potentials24 and magnetoencephalography (meg)5 magnetic evoked fields of contralateral primary somatosensory and ipsilateral second somatosensory cortices of 12 normal subjects were recorded in response to median nerve electrical stimulation by means of a single magnetometer. we detected. in addition to the usual con...

introduction:  the  use  of  mobile  communication  systems  has  dramatically  increased  over  the  past  decade. although many studies have been performed to determine the effect of radio frequency (rf) but  less attention has been paid to the possible biological impact of exposure to extremely low frequency  (elf) components.   the objective of this study is two folds. one is to design the ...

background: nowadays, magnetic nanoparticles (mnps) have received much attention because of their enormous potentials in many fields such as magnetic fluid hyperthermia (mfh). the goal of hyperthermia is to increase the temperature of malignant cells to destroy them without any lethal effect on normal tissues. to investigate the effectiveness of cancer therapy by magnetic fluid hyperthermia, fe...

in this paper, the hartree-fock method has been formulated to investigate some of the ground state properties of quasi-one-dimensional interacting electron gas in the presence of the magnetic field. the bare coulomb interaction between electrons has been assumed. for this system, we have also computed some of its thermodynamic and magnetic properties such as the energy, pressure, incompressibil...

mri workers are occupationally exposed to static and time-varying gradient magnetic fields.  while the 24-hour time-averaged exposure to static magnetic fields is about a few mt, the maximum static field strength can be as high as 500 mt during patient set up. over the past several years, our lab has performed extensive experiments on the health effects of exposure of animal models and humans t...

power stations produce a range of magnetic fields more than 20 mt which are harmful to those working or living around them. several investigators have reported an increased health risk due to exposure to electric and magnetic fields (emf) at 50 and 60 hz. several studies have been reported especially with increased tumor incidence, effects on reproduction and development, and neural and behavio...
