Nowadays jamming causes the major data loss in mobile communications. During the transmission time Anti-jamming technique can be used to transmit intermittently at low power in order to conserve energy. Here we use 802.11wireless network technology and this is to access the functions of the physical layer. There are two functions called Rate Adaptation and Power Control are used to find out whe...
Background: The widespread use of cell phones has led to an increase in concern about the effect of radiofrequency radiation on the physiology of the human body. This study was conducted to determine the different reaction temperatures of different brain tissue in exposure to mobile radiofrequency waves. Method: This was an experimental study. The cowchr('39')s brain tissue was examined in a c...
conclusions mobile phone text messaging increased adherence to diabetes therapy and improved the clinical outcome in saudi patients with type 2 diabetes. results in addition to significant improvement in patients’ knowledge, mean fasting blood glucose level improved from 8.60 ± 3.16 to 7.77 ± 3.11 mmol/l and mean hba1c decreased from 9.9% ± 1.8% to 9.5% ± 1.7%. objectives we conducted a study t...
because of the need to develop specific measurement scales for different services industries, this study aimed to empirically develop a reliable and valid model specifically for measuring mobile telecommunication service quality. a multidimensional measurement model (ms-qual) has been proposed based on an extensive literature review and then, to assess the model validity, convergent and discrim...
Background: Electromagnetic fields were made by electromagnetic radiations (EMR) of mobile phone (radio-frequencies 900 MHz). Various researches have shown that there are relationships between mobile phone electromagnetic exposure and cancer and neurologic damages. The aim of our study was to investigate the effects of mobile phone electromagnetic radiations (radio-frequencies 900 MHz) on learn...
Background: Excessive use of mobile phones is addictive and causes many complications. The severity of these complications depends on the duration of the call and the frequency of using mobile phones. Therefore, this study aimed to determine the effect of mobile phone waves on salivary secretion. Materials and Methods: This descriptive study was conducted on 120 dental students in Rafsanjan, Ir...
