Cancer of the breast is the second leading cause of cancer death among women worldwide. The majority of cancer of the breast cases (95%) is not hereditary. Can long-term cell phone use be linked to breast cancer? It is unlikely that electromagnetic radiation is involved, but it could possibly be due to the generated heat (cell phones only occasionally transmit when people are not talking on the...
Recent research on the impact of cell phones has largely focused on coverage and nonresponse error with few exceptions (Kennedy et al 2009, Brick et al 2011). In this work the authors focus on nonsampling error in the American Time Use Survey (ATUS). This nationally representative survey is conducted by the U.S. Census Bureau on behalf of the Bureau of Labor Statistics. The sample for the ATUS ...
Background: The widespread use of cell phones has led to an increase in concern about the effect of radiofrequency radiation on the physiology of the human body. This study was conducted to determine the different reaction temperatures of different brain tissue in exposure to mobile radiofrequency waves. Method: This was an experimental study. The cowchr('39')s brain tissue was examined in a c...
today, mobile phone as one of manifestations of new communication technology plays an important role in human individual and social life and it is included an inseparable part in their daily relations so that we can claim that life is impossible without it for many of people or at least it doesn't have any desirability. the influence of mobile phone applications in life different matters, ...
Little work has empirically examined the cognitive construct of situation awareness (SA) in driving tasks involving the use of advanced in-vehicle automated technologies and personal communication devices. This research investigated the effects of an adaptive cruise control (ACC) system, and cell phone use in driving, on a direct and objective measure of SA, and assessed the competition of mult...
With cell mobile phone devices becoming a basic part of life, the re-charging of cell mobile phone battery energy has always been a problem. The cell mobile phone devices differ in their talk-time and battery energy take a position by according to their producer and battery energy. All these mobile phones regardless of their producer and battery energy have to be put to renew after battery ener...
BACKGROUND The association between cell phone use and the development of parotid tumors is controversial. Because there is unequivocal evidence that the microenvironment is important for tumor formation, we investigated in the parotid glands whether cell phone use alters the expression of gene products related to cellular stress. METHODS We used the saliva produced by the parotid glands of 62...
background there is currently great concern about the possible adverse effect of microwave radiation from cell phones. in addition, noise is one of the physical pollutants of modern societies. objectives the present study aimed to examine the separate and simultaneous effects of cell phone microwaves, noise, and their effects on sperm parameters and total antioxidant capacity in adult male rats...
