In this research we have studied the effects of extremely low frequency magnetic field on the peripheral blood lymphocytes chromosomes of human in vitro and rat in vivo. By this means, we used 60 blood samples of 10 men as well as 40 rats. Of 60 human blood samples ,40 samples (in two group of 20) were selected as test groups and placed into the 2 mT and 35 Hz magnetic field. The blood samples,...

This communication influences on magnetohydrodynamic flow of viscoelastic fluid with magnetic field induced by oscillating plate. General solutions have been found out for velocity and shear stress profiles using mathematical transformations (Integral transforms). The governing partial differential equations have been solved analytically under boundary conditions u(0,t)=A_0 H(t)sinΩt and u(0,t)...

We show that in a spontaneously broken effective gauge field theory, quantized general background \(R_\xi \)-gauge, also the fields undergo non-linear (albeit background-gauge invariant) redefinition induced by radiative corrections. This proves to be crucial order renormalize coupling constants of gauge-invariant operators gauge-independent way. The classical background-quantum splitting is no...

introduction radiotherapy planning systems require many percentage depth dose (pdd) and profile measurements and there are various dosimeters that can be used to obtain these scans. as dose perturbation is particularly troublesome in smaller photon fields, using a low-perturbation, unshielded electron field diode (efd) in these fields is of interest. the aim of this work was to investigate the ...
