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...

This quantitative, qualitative study investigates the usage of mobile phone applications in teaching and learning processes.

The study was conducted in the English Department at Hebron University at the second semester of the academic years 2015/2016. The study focuses on the Business Engl...

Objectives: Most studies have performed to identify the affective variables in using mobile phone by drivers based on interview and questionnaire. In this study call answering rate while driving was investigated in a sample of male postgraduate students of a university in Tehran by a driving simulator. Methods: Six driving scenario designed differing in risk of driving. Answer rate to mobile...

Introduction:  The  use  of  mobile  communication  systems  has  dramatically  increased  over  the  past  decade. Although many studies have been performed to determine the effect of radio frequency (RF) but  less attention has been paid to the possible biological impact of exposure to extremely low frequency  (ELF) components.   The objective of this study is two folds. One is to design the ...

Introduction: The great use of electrical appliances in different life applications is one of the most obvious concerns because of its possible health drawbacks. These investigation reports results of electromagnetic field effect emitted from mobile phones on some biophysical parameters of human blood belonging to blood groups A, B, AB & O collected from the normal persons. The parameters obser...

background: the health effect of rapidly increasing everyday exposure of humans to radiofrequency radiation is a major global concern. mobile phone jammers prevent the mobile phones from receiving signals from base stations by interfering with authorized mobile carriers’ services. in spite of the fact that mobile jammer use is illegal, they are occasionally used in offices, shrines, conference ...
