Effects of radio waves on male fertility
In recent years, male fertility has changed due to the effects of environmental, health and lifestyle factors and the infertility rate has increased, to the extent that male fertility may be affected by extreme heat, exposure to pesticides, radiation, substances Changes in radioactivity, lifestyle, stress and occupation. In the environment, there are ionizing and non-ionizing rays whose effect...
متن کاملEvaluation of the effects of radio frequency waves and mobile phone distance on cow brain tissue temperature
Background and Aim: Considering the great advances and extensive use of cell phones and its effects on the human communications and interactions, investigation of potential negative effects of cell phones on the users' health is necessary. The aim of this study was to determine the effect of the distance between cell phones and brain tissue on the temperature of the central and gray matters of ...
متن کاملModulation of radio frequency signals by ULF waves
The ionospheric plasma is continually perturbed by ultra-low frequency (ULF; 1–100 mHz) plasma waves that are incident from the magnetosphere. In this paper we present a combined experimental and modeling study of the variation in radio frequency of signals propagating in the ionosphere due to the interaction of ULF wave energy with the ionospheric plasma. Modeling the interaction shows that th...
متن کاملActive control of edge localized modes by radio frequency waves
The effect of radio frequency wave driven torque on edge localized mode !ELM" activity is studied. It is shown that the radio frequency driven torque causes transition of type I giant ELMs to the benign grassy ELM behavior. The efficiency of this process scales directly with minor radius and inversely with the plasma density. It is argued that the technique of active ELM control will be efficie...
متن کاملHigh frequency ion sound waves associated with Langmuir waves in type III radio burst source regions
Short wavelength ion sound waves (2–4 kHz) are detected in association with the Langmuir waves (∼15– 30 kHz) in the source regions of several local type III radio bursts. They are most probably not due to any resonant wavewave interactions such as the electrostatic decay instability because their wavelengths are much shorter than those of Langmuir waves. The Langmuir waves occur as coherent fie...
