he use of hand-held mobile phones/cellular phones while driving is a known risk factor for road traffic accidents.1 In Iran, the use of mobile phones has increased dramatically in recent years. However, little research has been done to determine the prevalence of mobile phone use while driving in Iran. We conducted an observational, cross-sectional study to document patterns of mobile phone use...

Emergency Locator Transmitters (ELT) are generally the primary tool for locating distressed aircrews following an aircraft accident. In 2009, the International COSPAS-SARSAT organization ordered the cessation of 121.5 MHz ELT satellite monitoring to alleviate systemic false alarms and encourage pilots to upgrade ELTs to modern 406 MHz models. While most nations acquiesced to the mandate, the Un...

The good news is that cellular phones do not cause brain cancer. The bad news? They are unfortunately a cause of car accidents. In fact, according to research by Drs. Donald A. Redelmeier and Robert J. Tibshirani, driving with the use of a cell phone can be likened to driving with a blood alcohol level of about 0.10 per cent. The chances of getting into an car accident while using a cellular ph...

This paper presents a case of video streaming system for mobile phone which has actually been implemented and deployed for commercial services in CDMA2000 1X cellular phone networks. As the computing environment and the network connection of cellular phones are significantly different from the wired desktop environment, the traditional desktop streaming method is not applicable. Therefore, a ne...

In this paper, we present the design of Greystar, an innovative defense system for combating the growing SMS spam traffic in cellular networks. By exploiting the fact that most SMS spammers select targets randomly from the finite phone number space, Greystar monitors phone numbers from the grey phone space (which are associated with data only devices like laptop data cards and machine-to-machin...

The present study provides evidence that "in vitro" simple exposure of an aqueous solution of electric eel acetylcholinesterase (EeAChE; EC 3.1.1.7.) to cellular phone emission alters its enzymatic activity. This paper demonstrates, by combining different experimental techniques, that radio frequency (RF) radiations irreversibly affect the structural and biochemical characteristics of an import...

The cellular phone market has advanced rapidly and consequently has produced a variety of functional capabilities and interface designs. However, this same rapid proliferation has led to problems with the diffusion and organization of design guidelines. Given the current market demands on usability that include addressing the needs of users with disabilities, cellular phone developers need easy...

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...
