there area lot of mobile computer devices with a variety of applications and users tend to use them more. due to the limitations of mobile devices, running most of the procedures are impossible. to resolve this problem, mobile devices can be connected to the grid, to use the facilities of grid. on the other hand the communication mechanisms are different for each device and they cannot be conne...

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...
