Background & Aim: In recent years, health care workers' mobile phones have been considered important as a source of infection because they could have a significant role in nosocomial infections. The aim of this study is to determine the type of microbial contamination of health care workers' mobile phones in Sina hospital in Tabriz. Methods & Materials: In this descriptive-analytical study, ...
The evaluation of the exposure from mobile communication devices requires consideration of electromagnetic fields (EMFs) over a broad frequency range from dc to GHz. Mobile phones in operation have prominent spectral components in the low-frequency (LF) and radio-frequency (RF) ranges. While the exposure to RF fields from mobile phones has been comprehensively assessed in the past, the LF field...
background: the goals of the present work were to retrieve the scientific articles published on addiction to the internet, video games, and cell phones and to analyze the pattern of publications in this area (who is doing the research, when and where it is taking place, and in which journals it is being published), to determine the research being conducted as well as to document geographical t...
Background: Rapid advances in technology, especially in the field of telecommunication, have led to extraordinary levels of mothers’ exposures to radiofrequency electromagnetic fields (RF-EMFs) prior to or during pregnancy.Objective: The main goal of this study was to answer this question whether exposure of women to common sources of RF-EMFs either prior to or during pregnancy is related to ...
Background and Objective: Widespread use of cell phones and increased noise pollution in surrounding environment are the most important risk factors of human health in the age of technology. The aim of this study was to investigate the effects of mobile phone radiation and noise stress on serum levels of T3 and T4 in male rats. Materials and Methods: In this experimental study, the male Wist...
the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis,a one-way anova experimental design was carried out. 24 sednior students of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inter...
Currently, the problem of electromagnetic safety population has acquired social significance and is an urgent issue for modern development Republic Kazakhstan, as well other countries world. Environmental exposure to radiofrequency fields from mobile phones rapidly increased in last two decades this trend expected continue. Modern technologies have become a source pollution generated fields. Du...
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...
With the number of cellular phone users rapidly increasing, there is a considerable amount of public concern regarding the effects that electromagnetic fields (EMFs) from cellular phones have on health. People with self-attributed electromagnetic hypersensitivity (EHS) complain of subjective symptoms such as headaches, insomnia, and memory loss, and attribute these symptoms to radio frequency (...
Introduction: The process of puberty is one of the most important events of one’s life and onset of menstruation (menarche) is one of the important phenomena during the maturation process of females. Undoubtedly, genetics is the main determinant factor in the onset of puberty but several environmental factors contribute to the age of menarche. Objective: The purpose of this study was t...
