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: 70...

background:  wi-fi allows electronic devices such as laptops to exchange data or connect to a network resource. the main goal of this study was to assess the bioeffects of short term exposure to 2.4 ghz microwave radiation emitted from a common wi-fi router on sperm quality. materials and methods: male wistar rats were divided into 7 groups; i, sham exposed 4 h/day for 7days at 30 cm from the r...

Super Wi-Fi is a Wi-Fi-like network built upon TV white spaces (TVWS) exploiting cognitive radio (CR) techniques. Super Wi-Fi is expected to achieve larger coverage than today’s Wi-Fi thanks to its superior propagation characteristics, while suffering from smaller bandwidth compared to Wi-Fi (6–8 MHz versus 20 MHz) which limits its network capacity. Therefore, it has been a common belief that S...

We construct a new family of ${\mathrm{AdS}}_{2}\ifmmode\times\else\texttimes\fi{}{S}^{3}\ifmmode\times\else\texttimes\fi{}{S}^{2}$ solutions to type IIB supergravity arising as near-horizon geometries D1-F1-D3-D5-NS5-D7 brane intersections preserving four supersymmetries. show that subclass these asymptotes locally the ${\mathrm{AdS}}_{6}\ifmmode\times\else\texttimes\fi{}{S}^{2}\ifmmode\times\...

One of the characteristics Qur’an is its skill in articulating speech, which made eloquent Arabs prostrate themselves to eloquence. This noble book was revealed stunning ways that touch Arabs' being, capture their hearts and entertain minds. message intended reveal secrets hidden purposes diagnosing meanings abstract inanimate objects great bodies. The main question this research why does God p...

A s evidenced in Paleolithic cave paintings of fi sh dating from 17,000 years ago, human-fi sh interactions have existed for thousands of years (Valladas et al. 2001). The earliest interactions likely involved fi sh as food and were necessarily tied to geographic access (i.e., island or coastal locations). Over time, the establishment of farm fi shing and the emergence of modern capture and tra...

We present an evaluation of the ${\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}$ and ${K}^{\ifmmode\pm\else\textpm\fi{}}$ box contributions to hadronic light-by-light piece muon's anomalous magnetic moment, ${a}_{\ensuremath{\mu}}$. The calculation corresponding electromagnetic form factors (EFFs) is performed within a Dyson-Schwinger equations (DSE) approach quantum chromodynamics. These ar...
