Background: The radiation emitted from electromagnetic fields (EMF) can cause biological effects on prokaryotic and eukaryotic cells, including non-thermal effects. Objective: The present study evaluated the non-thermal effects of wireless fidelity (Wi-Fi) operating at 2.4 GHz part of non-ionizing EMF on different pathogenic bacterial strains (Escherichia coli 0157H7, Staphylococcus aureu...

male infertility is a distressingly common condition affecting about 1 in 20 of the male population. in a majority of the cases, the male partner produces sufficient numbers of spermatozoa to achieve fertilization but there are functional defects in these cells that prevent conception from occurring. in this study, the effects of wi-fi radiation on spermatogenesis, testes and testosterone of la...

In this paper we describe our configurable hotspot framework for ubiquitous interaction. A camera points to a physical space, the user defines interaction areas, and designs gestures by combining hotspots (rectangles) that detect simple 2D motions (left_right, top_bottom, etc.).

Background: The use of devices emitted microwave radiation such as mobile phones, wireless fidelity (Wi-Fi) routers, etc. is increased rapidly. It has caused a great concern; the researchers should identify its effects on people’s health. We evaluated the protective role of Vitamin C on the metabolic and enzymatic activities of the liver after exposure to Wi-Fi routers.Material and Methods: 7...

I discuss the nature of ‘hotspots’ and ‘jet knots’ in the kpc-scale structures of powerful radio galaxies and their relationship to jet-environment interactions. I describe evidence for interaction between the jets of FRI sources and their local environments, and discuss its relationship to particle acceleration, but the main focus of the paper is the hotspots of FRIIs and on new observational ...

„Shared WiFi-Communities“, deren Mitglieder private WLAN-Zugänge für die Nutzung durch Dritte frei geben, bieten ein großes Marktpotenzial. Nutzer können mittels mobiler Endgeräte über Hotspots anderer Community-Mitglieder kostenlos auf das Internet zugreifen oder mit der Bereitstellung von breitbandigem WiFi Geld verdienen. Zwischen Angebot und Nachfrage vermitteln überwiegend kommerzielle Ins...
