E-learning has acquired a prime place in many discussions recently. A number of research efforts around the world are trying to enhance education and training through improving e-learning facilities. This paper briefly explains one such attempt aimed at designing a system to support video clips in e-learning and explains how profiles of the presenters in video clips can be used to improve the u...

We address the problem of including Coulomb distortion effects in inclusive quasielastic (e, e) reactions using an improved version of the effective momentum approximation. Arguments are given that a simple modification of the effective momentum approximation, which is no longer applicable in its original form in the case of highly charged nuclei, leads to very good results. A comparison of the...

Using an effective lagrangian description we analyze possible new physics contributions to the most relevant muon number violating processes: μ → e γ and μ–e conversion in nuclei. We identify a general class of models in which those processes are generated at one loop level and in which μ–e conversion is enhanced with respect to μ → e γ by a large ln(mμ/Λ), where Λ is the scale responsible for ...

conclusions according to the results, six strains were resistant to six or seven antibiotics and all strains were at least resistant to two antibiotics. however, for each of these resistant bacteria one bacteriophage was isolated from environmental samples, which showed the effectiveness of bacteriophages to remove clinically resistant e. coli strains. effective phages in vitro showed effective...

 The Organization Readiness of Engineering Project Management Based on Virtual Teams has been analyzed in an Iranian Engineering firm. Adapting and analyzing the latest readiness model, experts’ opinions were received by questionnaires and main criteria of the readiness have been identified. The considered readiness criteria are: Infrastructure, Deliverables (Drawings, Reports, Minutes of Meeti...

background: despite the prevalence of non-alcoholic fatty liver disease (nafld) and non-alcoholic steatohepatitis (nash), no treatment has been proven to be effective in these common diseases. although many studies have shown that lifestyle modifications such as increasing physical activities and exercise could be effective in the treatment of these common diseases, the optimal strategy is stil...
