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...

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 ...

800x600 background: nowadays, mothers are continuously exposed to different sources of electromagnetic fields before and even during pregnancy.   it has recently been shown that exposure to mobile phone radiation during pregnancy may lead to adverse effects on the brain development in offspring and cause hyperactivity. researchers have shown that behavioral problems in laboratory animals which ...

This study aimed at examining the major mobile wireless technologies, that is,mobile phones and the possibilities associated with them, currently in use in theeducational domains, with an emphasis on language teaching and learning practices.Accordingly, some of the most typical studies using different functions of mobilephones such as e-mail, multimedia capabilities, Wireless Application Protoc...

The emergence of worldwide computing networks is often said to make us all inhabitants of a “global village”. It will not matter where you are in the world, you can still communicate with everybody else. You will be able to access relevant information regardless. This has not made us less mobile, however. On the contrary, we are more mobile than ever. It may sound like a paradox, but an impress...

Mobile cloud computing (MCC) is a new technology that has been developed to overcome the restrictions of smart mobile devices (e.g. battery, processing power, storage capacity, etc.) to send a part of the program (with complex computing) to the cloud server (CS). In this paper, we study a multi-cell with multi-input and multi-output (MIMO) system in which the cell-interior users request service...

Background: In recent years, the widespread use of microwave producing instruments specially mobile phones; result in growing concern regarding the possible effects associated with these waves on human health. Some studies highlight the possible health hazards of electromagnetic fields (EMF), while others contest the hypothesis of biological impact of EMF. The aim of this study was to evaluate ...

a mobile manipulator robot is known as a complex system due to some properties such as coupling between the manipulator and mobile chassis, holonomic and nonholonomic constraints, multivariable and nonlinear dynamics. the control of robot faces the external disturbance, parametric uncertainty and unmodeled dynamics. therefore, the use of an adaptive fuzzy system is suggested for its capability ...
