The aim of this paper is to establish the existence positive solutions by determining eigenvalue intervals parameters μ1, μ2, ..., μm for iterative system nonlinear differential equations order p wi(p) (x) + μi ai fi (wi+1 ) = 0, 1 ≤ i m, x∈ [0,1], wm+1 w1 (x), x ∈ satisfying non-homogeneous integral boundary conditions wi (0) wi' wi(p-2) wi(r) - ηi ∫01gi(τ)wi(r)(τ)dτ λi, where r {1, 2, p−2} bu...

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: 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...

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...

While Wi-Fi 5 is still sufficient for many organizations and businesses, it important to consider upgrade 6. This article discusses the main differences between The goal identify key metrics transmission of information content signals, a method determining best use signals certain categories use, an analysis study influence frequencies on quality transmitted information, also analyzes growth ra...
