Background: Extremely low frequency (0-300 Hz) fields from power lines, electronic equipment and medical devices, have been reported to produce various biological effects. Global system for mobile (GSM) is most largely used in everybody's life. This system utilizes a low frequency band as well as a high frequency range of electromagnetic field. This study investigated the effects of 217 Hz elec...

The electromagnetic field commutation relations are defined in terms of geometric factors that are double averages over two finite four-dimensional space-time regions. The square root of any of the uncertainty relations derived from the aforementioned commutators is taken as a critical field, in the sense that any electromagnetic field much larger than it can be treated as classical. Another cr...

The effects of noise on the calcium oscillations in a cell exposed to electromagnetic fields are described by a dynamic model. Noise is a very important factor to be considered in the dynamic research on the calcium oscillations in a cell exposed to electromagnetic fields. Some meaningful results have been obtained here based on the discussion. The results show that the pattern of intracellular...

Background: Electromagnetic fields interact with human tissues and may have adverse effects on fertility and reproduction. During the last decades there has been a growing concern on the effects of electromagnetic radiations on biological systems in general. Radiation risks from electromagnetic fields generated by processes such as reduced fertility and a significant decrease in implantation ra...

Work by Lund, Burr, Becker, and others leads to the inescapable conclusion that organisms tend to express quasisystemic electric changes when perturbed, and, conversely, will tend toward wellness either through endogenous repair currents or the application of equivalent external currents. We show that an all-inclusive electromagnetic field representation for living systems is fully consistent w...

As demonstrated by Chernodub, strong magnetic field forces vacuum to develop real condensates of electrically charged ρ mesons, which form an anisotropic inhomogeneous superconducting state similar to Abrikosov vortex lattice. As far as electromagnetic field behaviour is concerned, this state of vacuum constitutes a hyperbolic metamaterial [1]. Here we demonstrate that spatial variations of mag...
