background: there is a great concern for the possible adverse effects of radiofrequency radiations of cell phones. moreover, unwanted sound is one of the physical pollutants of current societies. thus, the present study was conducted to examine the effect of cell phone waves, sound, and simultaneous effect of cell phone waves and sound on sperm viability and total antioxidant capacity of blood ...

The high-β operating regime of spherical tokamaks (ST), such as in NSTX and MAST, make them attractive fusion devices. For access to such high β regimes, it is necessary to heat and to drive currents in ST plasmas. While such plasmas are overdense to conventional electron cyclotron waves, electron Bernstein waves (EBW) offer an attractive means toward this purpose. The applications of EBWs in S...

Plasma density oscillations (Langmuir waves) in the wake of an intense (Ipeak 3 1017W/cm2) laser pulse (100 fs) are measured with ultrafast time resolution using a longitudinal interferometric technique. Phase shifts consistent with large amplitude (Æne=ne 1) density waves at the electron plasma frequency were observed in a fully tunnel-ionized He plasma, corresponding to longitudinal electric ...

A kinetic theory of resonant interaction between electrostatic waves and the bounce motion of electrostatically trapped electrons is developed. Precise criteria are derived for the stability of electrostatic potential structures which trap electrons in a highly magnetized plasma. The theory explains the energy transfer from electron phase space holes to waves observed in simulations. It may als...

Abstract-The influence of temperature perturbations on the propagation and stability of low frequency waves in a weakly collisional plasma is analyzed. Temperature oscillations in general reduce the stability of ion acoustic waves. It also tends to lower themagnitude of the critical current necessary for triggering the instability. In the case of drift waves its effect is to change the destabil...
