Camera phones are ubiquitous, and consumers have been adopting them faster than any other technology in modern history. When connected to a network, though, they are capable of more than just picture taking: Suddenly, they gain access to the power of the cloud. We exploit this capability by providing a series of image-based personal advisory services. These are designed to work with any handset...

Introduction: Mobile phones are in close contact with body serving transportation of bacteria in hospital settings. Further, sharing of mobile phones among health care workers & non Health care workers distinctly facilitate the spread of potentially pathogenic bacteria to the community. Aims & Objective: To study the bacterial flora present on cell phones of II & III MBBS students & to compare ...

background: pre-exposure to radiofrequency radiations of mobile phones would significantly increase the survival rate of exposed animals compared to those exposed to a lethal dose of gamma radiation alone. stimulation of the immune system is believed to be a key mechanism for the induction of this phenomenon, the so-called “adaptive response.” the immune system protects organisms against infect...

The International Agency for Research on Cancer classifies radiofrequency (RF) electromagnetic emissions of cell phones as possibly carcinogenic to humans [1] and suggests the use of hands-free devices such as earphones to reduce direct exposure of the brain to such emissions. In this paper, we present the design of a mobile application that exploits persuasive principles to encourage the use o...

Modern cell phones are a ubiquitous resource with a residual capacity to accommodate chemical sensing and biosensing capabilities. From the different approaches explored to capitalize on such resource, the use of autonomous disposable lab-on-a-chip (LOC) devices-conceived as only accessories to complement cell phones-underscores the possibility to entirely retain cell phones' ubiquity for distr...

RE: " CELLULAR TELEPHONE USE AND RISK OF ACOUSTIC NEUROMA " Christensen et al. (1) recently presented results on the use of cellular telephones and the risk for acoustic neuroma. However, in our opinion, several issues need to be clarified in the paper. Our main concern is that the study did not take into account exposures from cordless phones, and associations specific for ever use of analog o...

BACKGROUND The use of cellular and cordless telephones has increased dramatically during the last decade. There is concern of health problems such as malignant diseases due to microwave exposure during the use of these devices. The brain is the main target organ. METHODS Since the second part of the 1990's we have performed six case-control studies on this topic encompassing use of both cellu...

The possible risks of radio-frequency electromagnetic fields for the human body is a growing concern for our society. We have previously shown that weak pulsed microwaves give rise to a significant leakage of albumin through the blood-brain barrier. In this study we investigated whether a pathologic leakage across the blood-brain barrier might be combined with damage to the neurons. Three group...

The aim of this paper is to investigate the pedagogic approach that best support effective use of cell phones in the distance education context. Many distance education scholars agreed that students need to be supported both cognitively and affectively through mediated forms of interaction. Distance education institutions have used a variety of technologies to enhance interaction but none has b...

Human exposure to radio frequency radiation has increased dramatically during recent years from widespread use of mobile phones, and in some studies this exposure has been linked to the development of acoustic neuroma. The aim of our study was to describe the epidemiology of acoustic neuroma in a newly developed country, Qatar. We reviewed all cases of acoustic neuroma registered at the Hamad M...
