This study investigates that the sound wave propagation of multiferroic thermo elastic Nanofibers under the influence of surface effect and parametric excitation via Timoshenko form of beam equations. The equation of analytical model is obtained for Nanofiber through shear and rotation effect. The solution of the problem is reached through the coupled time harmonic equations in flexural directi...

background: despite therapeutic effect of hemodialysis in end stage renal disease (esrd) patients, these patients encounter different physical and psychological tensional factors. physical exercises have beneficial physical and psychological effects on patients under hemodialysis as one of the accessory therapeutic methods. as few studies have been done about the effects of physical exercise on...

Stages of Diversification in a Neoclassical World Recent research has documented a U-shaped industrial concentration curve over an economy’s development path. How far can neoclassical trade theory take us in explaining this pattern? We estimate the production side of the Heckscher-Ohlin model using industry data on 44 developed and developing countries for the period 1976-2000. Decomposing the ...

The hydrologic mechanisms underlying the climate-soil-vegetation dynamics and thus controlling the most basic ecologic patterns and processes are described as one very exciting research frontier for the years to come. In this personal opinion I have concentrated on those processes where soil moisture is the key link between climate fluctuations and vegetation dynamics in space and time. The soi...

We have fabricated field effect transistors in order to study charge trapping in pentacene transistors and charge noise in a variety of organic field effect transistors.

state divisions are one of the most effective tools for political space organizing. the background of dividing the territory of the country into smaller units in iran may be historically traced back to the formation of the first territorial state by achaemenids. the role and function of state divisions, its relationship to national survival, facilitation of exerting the government’s will, a bal...

Two Cu-Co and Co3O4 oxides were synthesized by the conventional sol-gel auto-combustion and their physical-chemical properties were characterized by XRD, FTIR, SEM, TPR and XPS. The XRD results indicated that copper-cobalt oxide appeared in a mixture form of Cu0.15Co2.85O4 spinel and CuO phases, whereas the cobalt oxide exhibited in the pure form of Co3O4 spinel. The FTIR approved the formation...
