In this study, we investigated the effect of a heat source on blood flow through gradient-tapered vessel under influence gradient magnetic field by reformulating problem using mathematical model representing momentum and energy equations. The partial differential equations were dimensionlessly scaled scaling parameter further reduced to system ordinary A coupled regular was solved series method...
background: magnetic nanoparticles in a variable magnetic field are able to produce heat. this heat (42-45°c) has more selective effect on fast dividing cancer cells than normal tissues. methods: in this work magnetite nanoparticles have been prepared via co-precipitation and phase identification was performed by powder x-ray diffraction (xrd). magnetic parameters of the prepared nanoparticles ...
introduction magnetic fields are capable of altering the trajectory of electron beams andcan be used in radiation therapy.theaim of this study was to produce regions with dose enhancement and reduction in the medium. materials and methods the ndfeb permanent magnets were arranged on the electron applicator in several configurations. then, after the passage of the electron beams (9 and 15 mev va...
Various studies have been done on the effective factors that cause the emanation of radon gas as the earthquake forecast from the earth. In this study, Magnetic field is examined and the effect of weak magnetic fields of up to 40 gauss applied to paper and aluminum membranes is measured. The results indicate an increase in the diffusion coefficient versus the increase of the applied magnetic fi...
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...
This paper investigates damping ratio in micro-beam resonators based on magneto-thermo-elasticity. A unique aspect of the present study is the effect of permanent magnetic field on the stiffness and thermo-elastic damping of the micro resonators. In our modeling the theory of thermo-elasticity with interacting of an externally applied permanent magnetic field is taken into account. Combined the...
Background and aims: Extremely low frequency magnetic field (ELF) is part of Spectrum of electromagnetic waves with range 30 to 300 Hz. The average magnetic field exposures in the workplace have been found to be higher in “electrical occupations” than in other occupations such as office work. The interaction between magnetic fields produced by power lines and substations with living organisms a...
In this paper, we present a numerical study of turbulent natural-convection in square cavity differentially heated and filled with nanofluid subjected to an inclined magnetic field. The standard k-? model was used as the turbulence model. transport equations were discretized by finite volume method using SIMPLE algorithm. influence Rayleigh number, Hartmann orientation angle applied field, type...
