original article background and objectives: one type of electromagnetic fields, based on frequency range, is extremely low frequency (elf) fields. there are lots of reports about measuring elf- magnetic field (mf) in substations, power plants, cities, near high voltage power lines and etc. this study aimed to compare the difference between measurement of three-axis and single-axis probe mf mete...
Background The aim of this study was to investigate the effect of applying the 1-mT magnetic field (MF) in the ovarian tissue vitrification. MaterialsAndMethods Ovaries of 6-8 week-old Naval Medical Research Institute female mice randomly were divided into 5 groups: V1: Ovaries that immediately after leaving of the mice body, were examined histologically (control group), V2: Ovaries that withou...
Introduction Range and diffusion of positron-emitting radiopharmaceuticals are important parameters for image resolution in positron emission tomography (PET). In this study, GEANT4 toolkit was applied to study positron diffusion in soft tissues with and without a magnetic field for six commonly used isotopes in PET imaging including 11C, 13N, 15O, 18F, 68Ga, and 82Rb. Materials and Methods GEA...
The magnetization and the critical current density of newly discovered NdO0.82F0.18FeAs superconductor with a critical temperature, Tc,, of 51.5 K has been studied as a function of applied magnetic field and temperature. It was found that this compound exhibits a standard superconductivity with diamagnetic onset close to Tc at a very low applied magnetic field. It was shown that there was a str...
