Social identity is a constant and permanent process that changes social situations based on individual experiences in these situations. Religious and ethnic identities are two dimensions of social identity that are of great importance in Iranian society. Due to the ethnic diversity in Iran and the proximity of ethnic cultures through migration, ethnic identity is noticeable. Religious identity ...

the thermal decomposition of 86 % vinyl chloride 14 % vinyl acetate copolymer wasstudied by the conductometry technique in the presence of nitrogen. the kinetics of stability andthermal degradation of vinyl chloride- co- vinyl acetate (pvc- co- pvac) copolymer withcopper, copper oxide and tricalcium dicitrate (st) were investigated at various temperatures (150-180 oc ) in solution. the rate coe...

Isothermal redox kinetics of as-received Co3O4 (AC), 1 h ball milled Co3O4 (BC), and 1 h ball milled Co3O4-15wt.% Fe2O3 (BCF) was investigated at various temperatures (1130, 1100, 1070, and 1040 °C for reduction and 830, 860, and 890°C for re-oxidation) by thermogravimetric method. It was found that mechanic...

There are several obstacles to the commercialization of PEM fuel cells.  One of the reasons is that the presence of carbon monoxide (CO) in the reformatted fuel, even at a very small scale, decreases the fuel cell performance. The aim of this paper is to investigate the effect of CO in reformatted fuel on PEM fuel cell performance. For this purpose, a steady state, one-dimensional and non-isoth...

Two different possible mechanisms of water gas shift reaction including formate and redox mechanisms on the Ag5 cluster were investigated using DFT computations. All the elementary steps involved in both mechanisms were considered. It was observed that dissociation of H2Oads and OHads, as well as formation of CO2(ads), required activation e...

This article explores the advantages and one potential implementation of a new style of computation in which multiple lines of symbolic processing are pursued at different speeds within a hybrid multi-agent system. The cognitive architecture DUAL consists of small hybrid computational entities called DUAL agents. Each agent has a symbolic processor capable of simple symbol manipulations. There ...

Purpose: Despite the widespread use of cryotherapy in sports fields there is a lack of certain evidence of its impact of it on muscle activation especially following fatigue-induced exercise. This study aimed to assess the impact of cryotherapy alone and after plyometric exercises on knee muscle activation during the drop jump task. Method: 35 active female subjects (mean age of 22.74±2.10, m...
