The data stored on mobile phones is a common source of investigative and evidential material, but there may be further useful information available such as Call Detail (or Data) Records linked to the SIM card used, held by network operators for billing purposes. Historic Cell Site Analysis involves the analysis of these records, in conjunction with other information such as survey and geographi...
The main objective of this paper is to argue how the mobile phones have transformed the Iranian lifestyle and how the arrival of mobiles has been a catalyst for revolting behavior, and has launched a new consumer behavior and has changed our relationships. The paper explains how the people's behavior has developed a whole new social code in Iran. It is argued that the social value of being able...
We investigated the effects of mobile phone radiation on cerebral glucose metabolism using high-resolution positron emission tomography (PET) with the (18)F-deoxyglucose (FDG) tracer. A long half-life (109 minutes) of the (18)F isotope allowed a long, natural exposure condition outside the PET scanner. Thirteen young right-handed male subjects were exposed to a pulse-modulated 902.4 MHz Global ...
Introduction: The rapid development of wireless telecommunication technologies over the past decades, has led to significant changes in the exposure of the general public to electromagnetic fields. Nowadays, people are continuously exposed to different sources of electromagnetic fields such as mobile phones, mobile base stations, cordless phones, Wi-Fi routers, and power lines. Therefore, th...
Mobile phones and Wi-Fi radiofrequency radiation are among the main sources of the exposure of the general population to radiofrequency electromagnetic fields (RF-EMF). Previous studies have shown that exposure of microorganisms to RF-EMFs can be associated with a wide spectrum of changes ranged from the modified bacterial growth to the alterations of the pattern of antibiotic resistance. Our l...
Background Mobile phone has played an increasingly important role in people’s lives; however, there is a global concern that it may cause adverse effects on health. This study aimed to assess the effect of educational intervention based on Health Belief Model (HBM) to d...

The GSM--Global System for Mobile Communication meets all relevant requirements, and it is most widely used throughout the world. According to the mobile phone concept, the whole communication area is divided into sub-areas (cells) where base ...
conclusions mobiles contamination with different pathogens is extremely common among our health care staffs compared with other societies, and resistance of these isolates to various antibiotics is also detectable. thus, quick assessment of this issue to prevent the spread of these infectious agents is critical for the authorities in our health care systems. results in total, 99.2% of mobile ph...
Twenty volunteers participated in two experiments exploring the acute effects of using the mobile phone Motorola GSM 8700 on the functions of the CNS. When speaking (5 minutes reading a text from daily newspapers) the electromagnetic fields from the mobile apparatus did not affect the visual evoked potentials. Also a 6-min exposure did not reveal any effect of electromagnetic fields on the resu...
