BACKGROUND There is tremendous concern regarding the possible adverse effects of cell phone microwaves. Contradictory results, however, have been reported for the effects of these waves on the body. In the present study, the effect of cell phone microwaves on sperm parameters and total antioxidant capacity was investigated with regard to the duration of exposure and the frequency of these waves...

I review the expected Galactic sources of gravitational waves, concentrating on the low-frequency domain and summarise the current observational and theoretical knowledge we have. A model for the Galactic population of close binaries, which is tested against the observations is used to predict the expected signal for the future space based gravitational wave detector LISA. With a simple model f...

We examine the motion of charged particles in gravitational and electro-magnetic background fields. We study in particular the deviation of world lines, describing the relative acceleration between particles on different space-time trajectories. Two special cases of background fields are considered in detail: (a) pp-waves, a combination of gravitational and electro-magnetic polarized plane wave...

Background Low birth weight is one of the most important health indicators in evaluating pregnancy care worldwide. We aimed to evaluate the effect of cell phones used in pregnancy on fetal growth and preterm labor. Materials and Methods The search process included screening the rel...

most popular sources for electromagnetic waves. However, there are many concerns regarding their biological effects on the body, especially the central nervous system. Therefore, the aim of this study was to evaluate the effects of cell phone radiation on histology of the cerebellar granular cells in the neonatal rat. Materials and methods: We selected some Wistar rats. Then, we randomly d...

• Optical property of a material is defined as its interaction with electro-magnetic radiation in the visible. • Electromagnetic spectrum of radiation spans the wide range from γ-rays with wavelength as 10 m, through x-rays, ultraviolet, visible, infrared, and finally radio waves with wavelengths as along as 10 m. • Visible light is one form of electromagnetic radiation with wavelengths ranging...

background: a lot of investigations exist on the biological effects of radiofrequency and microwave radiation however only a few studies have considered non-carcinogenic exposure to radiations specifically from mobile phones. objectives: to introduce some subjective neurological symptoms in mobile phone users. materials and methods: in this cross-sectional descriptive study conducted from march...
