the study comparatively identified the benefits of mobile telephone to users in selected rural and urban locations in obio/akpor local government area of rivers state, nigeria. stratified and simple random sampling techniques were used in selecting 60 rural and 60 urban phone users to have a total sample size of 120 respondents. structured questionnaire was used to generate data that were analy...

With the rapid development of the computing and Internet access (i.e., using WiFi, GPRS and 3G) capabilities of smartphones, constructing practical mobile botnets has become an underlying trend. In this paper, we introduce the design of a mobile botnet called Andbot which exploits a novel command and control (C&C) strategy named URL Flux. The proposed Andbot would have desirable features includ...

Despite the very high penetration of the private sector with mobile devices, only few applications and services based on mobile technologies are used, and those are rather trivial. This article suggests an approach for the identification of alternatives for the support of processes of everyday life by launching and establishing services based on mobile applications, mobile devices, and infrastr...

the exposure to electromagnetic field emitted by mobile telephones is increasing rapidly worldwide that causes side effects, including thermal and non thermal side effects. ear proximity to electromagnetic source may lead to greater damage and side effects, including hearing loss. this study was performed to assess the chronic effect of exposure to electromagnetic field of mobile telephones on ...

A high performance liquid chromatography method was studied for determination of 18 ?-glycyrrhetinic acid in Glycyrrhiza glabra L. (licorice) extract. The operating condition were C-18 reversed phase column (VP-ODS, (250×4.6 mm, 5 mm)) at room temperature, acetonitril/phosphoric acid (3/1) as mobile phase, at flow rate of 0.6ml/min (0-8min), 0.4ml/min (8-20min) and UV detection at 230 nm. The...

Designing a secure and reliable mobile agent system is a difficult task. The agent operating system (AOS) is a building block that simplifies this task. AOS provides common primitives required by most mobile agent middleware systems, such as primitives for secure communication, secure and tamper-evident agent packaging and agent migration. Different middleware processes can use AOS at the same ...

A stability indicating High-Performance Liquid Chromatography (HPLC) method wasvalidated and used to study the degradation of cetirizine dihydrochloride in acidic and oxidativeconditions. The separation was carried out on a Symmetry C18 column and a mixture of 50 mMKH2PO4 and acetonitrile (60:40 v/v, pH = 3.5) was used as the mobile phase. The method waslinear over the range of 1-20 μg/mL of ce...
