− The theory of electromagnetic shielding is based on the waves equations describing the behavior of electromagnetic field in substance and also boundary phenomena by means of Fresnel’s reflection and transmission coefficients. The interaction between electromagnetic radiation and infinite plane shield having finite thickness d, placed in free space in plane waves region depends of material/shi...

a new medium, termed ecol was developed for the detection and enumeration of e. coli. the selective properties of ecol medium for the detection of e.coli from mixed culture in wastewater was tested and compared with conventional coliform media at 37°c and 44°c. results clearly showed that ecol medium was enable to direct confirmation of e.coli to be carried out by the indole reaction. the resul...

Tensile membrane structures were the focus of extensive research during a four year FP6 project Contex-T. This project brought together experts from different disciplines to bring the technology for building membrane structures forward. Membrane materials, tension devices, supporting structure, comfort and safety aspects of membrane constructions were studied. This has resulted in a number of s...

In this paper, a new version of the traffic generator script “cbrgen.tcl” to the Network Simulator (NS-2) was developed and applied in many simulation experiments. The main objective of this paper was to study the impacts of varying the transmitted (sent) data rate for the CBR and TCP traffic under varying number of nodes. The performance of MANETs traffic pattern was evaluated with respect to ...

Health[1] Health[1]Biotechnology [2]Diseases [3]Health [4]Medicine [5]The Body [6]Denmark [7]Videnskab.dk [8] Danish scientists have developed a new vaccine against tuberculosis. The vaccine was created in an entirely new way and may potentially save millions of lives, say the researchers. Tuberculosis annually kills some 1.4 million people, making it one of the world’s deadliest diseases. This...

Political culture in Iran, the changes in it, factors causing these changes and their proba-ble outcomes have been of interest to writers and researchers at the present time more than ever; as a result, the concept of political culture, which is a newly developed con-cept in the political studies and research in Iran, is regarded as of great importance in these studies. Similarly, the number of...

Based on work in media studies, new literacy studies, applied linguistics, the arts and empirical research on the experiences of urban youths’ informal media arts practices we articulate a new vision for media education in the digital age that encompasses new genres, convergence, media mixes, and participation. We first outline the history of how students’ creative production has been used to m...
