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 کاملMAPK activation by radio waves.
In this issue of the Biochemical Journal, Freidman et al. report the findings of a study to look at the potential of mobile phones to activate intracellular signalling cascades. They found that radio waves corresponding to the frequency commonly used by mobile phones are able to activate ERK1/2 (extracellular-signal-regulated kinases 1 and 2). This effect was observed even at intensities lower ...
متن کاملRadio Waves for Space-Based Construction
This paper follows up on the idea of using potential fields for automatic construction of massive objects of desired shape in Space. In STAIF03, we showed the commonality between the theories for acoustic and optical positioning/shaping methods. Using this theoretical framework, we developed a simple engineering estimation scheme to predict the acceleration per unit intensity. The radiation pre...

متن کاملTwisted Radio Waves and Twisted Thermodynamics
We present and analyze a gedanken experiment and show that the assumption that an antenna operating at a single frequency can transmit more than two independent information channels to the far field violates the Second Law of Thermodynamics. Transmission of a large number of channels, each associated with an angular momenta 'twisted wave' mode, to the far field in free space is therefore not po...
