Introduction Abnormal neural impulses in the nervous system may lead to various diseases and disabilities. High frequency alternating currents (HFAC) has been used to block the propagation of such impulses and improve the symptoms or disabilities. The technique is safe, reversible, and relatively selective, and its reliability, the optimum stimulation parameters, and elimination of the onset re...

Abstract: In this study, the effects of variation of thickness and the number of quantumwells as well as the contact length were investigated. In this paper, a vertical cavity surfaceemitting laser was simulated using of software based on finite element method. Thenumber of quantum wells was changed from 3 to 9 and the results which are related tooutput power, resonance ...

Epoxy nanocomposites with multiwall carbon nanotubes (MWCNTs) filler up to 0.3%wt were prepared by shear mixing and good dispersion of the MWCNTs in the epoxy was successfully achieved. The electrical behaviour was characterized by measurements of the alternating current (AC) and direct current (DC) conductivities at room temperature. Typical percolation law behaviour was observed with a low pe...
