this paper presents an approach to modeling of field penetration and gives contribution to understanding the real effects of the fields and the sensitivity of human model to electromagnetic radiation generated by mobile antenna. when a human body is exposed to the electromagnetic radiation, because human body contain 70% of liquid, and it contain more liquid near of head, heart, abdomen (near o...
for many years it was believed that extremely lowfrequency electromagnetic field (elf-emf) do not have any significant biological effects. in this study, the influence of extremely low-frequency electromagnetic fields on the growth performance, serum antioxidant power and gastrointestinal structure of rainbow trout were evaluated. rainbow trout (17-18 g) were exposed to electromagnetic fields (...
introduction: the aim of the present study is to investigate the effect of interaperitoneal injection of baclofen (gaba-b agonist) and cgp35348 (gaba-b antagonist) on serum testosterone concentration in aggressive rats exposed to electromagnetic field. methods: fifty five mature male rats weighing 200±20 grams were studied. animals were divided into 2 main groups and four subgroups. main groups...
drop plate technique has a priority and preference compared with the spread plate procedure, because of less time, quantity of media, effort requirement, little incubator space, and less labor intensive. the objective of this research was to compare the accuracy and fidelity of drop plate method vs. spread plate method by parametric and nonparametric statistical tests. for bacterial enumeration...
in this paper are present the results of measurements of magnetic induction at some locationsin city bor (the east serbia) dating from the household electric devices and transformer stations suited near the residental areas. stress is on the extremely low frequent electromagnetic radiation from transformer stations and other high voltage instalations in urban areas. risk of the extremely low fr...
The principle of calculation a plate from metamaterial with inductive type chiral inclusions is submitted. It shown that distribution an electromagnetic wave to such substance can be investigated the help introduction parameter and on basis detailed method calculation. By comparison two methods dependence frequency radiation falling found. With nonlinear differential equation for potential this...
In this research, the effects of electromagnetic fields of various strengths (0, 1 and 2mT) have been investigated on antioxidant enzymes activity in Valerian (Valeriana officinalis L.). The dry and wet (soaked for 30 min) Valerian seeds were exposed to electromagnetic fields 30 min per day for 3 days. Each treatment and control groups had 3 replicates and 10 seeds were employed for each replic...
Introduction: The highest electromagnetic radiation pollution is related to the radiofrequency waves of mobile phones (1). Up to 70% of these waves can be absorbed by various tissues (2). Absorption of these waves can damage the body tissues by causing oxidative stress (3). Given that melatonin plays an antioxidant role, it seems that this hormone can have a protective effect on the hepato- tox...
background: exposure to extremely low frequency electromagnetic fields is increasingly common, but the potential influence on pregnant women has not been thoroughly investigated. methods: in this case-control study, 58 women who had an unexplained spontaneous abortion at < 14 weeks gestation and 58 matched pregnant women >14 weeks gestation were enrolled in 2012. the women completed the questio...
Currently, many children undergo precocious puberty, resulting in short stature due to premature closure of the growth plate. Pulsed electromagnetic field (PEMF) stimulation induces cell proliferation articular chondrocytes. We developed a method for promotion using equipment with PEMF. In this study, we aimed evaluate effects PEMF on rate plates an animal model. An experimental study was condu...
