within the effective-field theory with correlations (eft), a transverse random field spin-1 ising model on the simple cubic (z=6) lattice is studied. the phase diagrams, the behavior of critical points, transverse magnetization,  internal energy, magnetic specific heat are obtained numerically and discussed for different values of p the concentration of the random transverse field.

BACKGROUND Submaximal eccentric exertions occur occupationally when rapidly rising tool-generated forces exceed the operator's capacity to react against them. The purpose of this study was to investigate the effects of short duration repetitive submaximal eccentric forearm exertions at levels comparable to industrial power hand tool use on dynamic mechanical properties (stiffness, effective mas...

statement of problem: dental resin composites are becoming prevalent in restorative dentistry and have almost replaced amalgam nowadays. consequently, their mechanical properties and durability are critical. objectives: the aim of this study was to produce pyrex glass nano-particles by wet milling process and use them as reinforcement in dental resins for anterior restorations and then examinat...

in the present study, the microstructure and mechanical properties of the dissimilar welding betweenastm a335 low alloy steel and er309l austenitic stainless steel were investigated using the gastungsten arc welding process. the welding of dissimilar materials between astm a335 low alloy steeland er309l austenitic stainless steel was found to have a significant effect on the microstructure when...

this study prepared new edible composite film by blending kefiran with whey protein. the film-forming solutions used different ratios of kefiran to whey protein (70/30, 50/50, 30/70, 10/90) and were cast at room temperature. the effects of the addition of whey protein on the physical, mechanical and water-vapor permeability (wvp) properties of the film were investigated. it was found that an in...

in this paper, we have used density functional perturbation theory (dfpt) and pseudo-potential method to calculate the phonon spectrum, phonon density of states (dos), specific heat capacity and mechanical properties of (5,5) armchair and (9,0) zigzag single wall carbon nanotubes (swcnts). our calculations show that young’s modulusfor (5,5) and (9,0) nanotubesare higher than 1tpa. we have also ...

excellent mechanical properties of carbon nanotubes (cnts) make them outstanding candidate reinforcements to enhance mechanical properties of conventional composites. the glass/polyester composites are widely used in many industries and applications. improving the mechanical properties of such composites with addition of cnts can increase their applications. in this research, multi-walled carbo...

carbon nano-tube (cnt) reinforced metal matrix nano-composites have attracted a great deal of attention in recent years due to the outstanding physical and mechanical properties of cnts. however, utilizing cnt as reinforcement for alloy matrixes has not been studies systematically and is still a challenging issue. in the present study, cu80fe20/10cnt nanocomposite was synthesized by mechanical ...
