Introduction: In recent years, the rapidly increasing use of mobile phone operating nearby the human head has caused public concern for its effects on human health. The FDTD methodology is widely used for calculation of the effects of electromagnetic fields on human body. Methods and Materials: In this paper, first a dual band patch antenna structure (GSM-900 and DCS 1800), which is located i...
This paper presents results from a study on mobile phone use to connect two rural hospitals in Malawi with community health workers (CHWs), the hospitals work with. Mobile phone use at the hospitals has helped reduce the need for face-to-face communication to permit patient information exchange, meetings and appointments scheduling, as well as work coordination. On the other hand mobile phone u...
objective: electro-magnetic radiation (emr) is emitted from mobile phones. various researches have shown relationships between mobile phone emr exposure to cancer and neurologic damages. this study aims to investigate the effects of mobile phone emr on brain antioxidant enzyme activity and the learning process. methods: rat pups and their dames were exposed to emr for 3 h per day from p2 to p1...
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...
Mobile phone use is banned or regulated in some circumstances. Despite recognized safety concerns and legal regulations, some people do not refrain from using mobile phones. Such problematic mobile phone use can be considered to be an addiction-like behavior. To find the potential predictors, we examined the correlation between problematic mobile phone use and personality traits reported in add...
The present study employs standardized data acquired from the Brain Resource International Database to study the relationship between mobile phone usage, personality, and brain function (n = 300). Based on the frequency and duration of mobile phone usage, three groups were formed. The findings suggest a subtle slowing of brain activity related to mobile phone use that is not explained by differ...
