Background: Neuritis is one of the causes of neuropathic pains. It is proved that turmeric and curcumin have anti-neuritis effect that may be reduce of neuropathic pain. Objective: In this study, effects of turmeric and curcumin have been evaluated on behavioral response resulted from chronic constriction injury (CCI) in rat. Methods: In this experimental study Wistar male rat (200-250 gr) were...

in saturated soils, heating induces thermal expansion of both grains and the pore fluid. lower thermal expansion coefficient of aggregates results in the increase of pore pressure and reduction of the effective stress besides subsequent volume changes due to the dissipation of pore pressure and heat transfer. dissipation of thermally induced pore pressure with time is a coupled thermo-hydro-mec...

Pressure vessel is a container used to store fluids under pressure and temperature. The fluids can be air, water, chemicals, fuel, gases etc. are most commonly used in food and chemical industries, oil refineries and so on. Pressure vessel is subjected to thermal and structural loads for power plant applications. Since the pressure vessel are subjected to both structural and thermal loads stres...

Fly ash (FA) is produced as a waste byproduct during the burning process of coal in thermal power plants whose cost is primarily associated to cleaning and transportation. It possesses mechanical properties on account of its constituents like silica and alumina. The use of FA as filler in styrene butadiene rubber (SBR) was of researchers’ interest to reinforce and/or to reduce product cost. In ...

A novel Starch/Poly (vinyl alcohol)/nano-Titanium dioxide (ST/PVA/nano-TiO2) biodegradable nanocomposite film was prepared by homogeneously dispersed TiO2 nanoparticles in different ratios of starch/PVA-based materials, via a solution casting method. Glycerol was used as plasticizer. The mechanical and thermal properties of films were studied using tensile and perforation strength tests and the...

A lthough an economic analysis will usually show that process-yield improvements and cycletime considerations have a far larger effect on the total cost of ownership, price is usually seen as the most important consideration when choosing an alignment system. Yet price should not be the single determining factor. True, system improvements to increase coupling yield are limited by prices that th...

A comprehensive experimental study performed under a combination of thermo-electro-mechanical loads applied to widely used electro-active polymer, is presented in the Part I this work (Mehnert et al., 2021). Soft polymeric materials, as base materials polymers, are highly susceptible temperature changes. Hence, thermal influences on their behavior have be investigated precisely. Constitutive mo...
