in this paper an indirect method is presented to detect potential geothermal sites in kerman province, southeast iran. geothermal heat flux is one of the main parameters to be investigated in geothermal exploration programs. however, few direct heat flux measurements are available for iran. given the proved relation between curie depths and heat flux, magnetic data can be used to calculate the ...
in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
introduction: public and occupational exposure to extremely low frequency (elf) electric and magnetic fields induced by electrical equipment is a significant issue in the environment and at the workplace due to their potential health effects on public health. the purpose of this study was assessment of the electric and magnetic fields intensities and determination of mental and psychological ef...
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 ...
