In order to gain and sustain a competitive advantage, today's organizations need to effectively mobilizetheir change. The purpose of this study is determining the relationship between Organizational Structure and staff resistance in front of change in Fars Province Physical Education Managers. The method of the research is descriptive and its type is correlation between variables and - in view of theoretical and scientific basis of the present study - it could be categorized as applicational. The statistical corpus in this study was comprised of the heads and deputies in various counties in Fars province physical education organizations of whom n=46 were opted out by the method of full-counting sampling as the population of the research. Yet again, the toolkit to gather data was the standard questionnaire of Robins organizational structure, in addition to the questionnaire as to the resistance against change the suitability and the stability of Robins standard questionnaire have been made mention of in various national and international source studies (α=./86). The permanency of the resistance +questionnaire again in the present work (against change) was calculated through the method of kronbach Alfa coefficient testing (α=./83). The analysis of the data was accomplished with the application of inferential and descriptive statistics (like Pearson co-variation and Klomgrev-Smirhev testing. The level of significance of either α=/05 or α=/01were determined through excel and spss software. Findings: The results showed that there was significant relationship between organizational structure and staff resistance against change (P>/05). Moreover, There was significant and positive relationship between formalization, complexity & centralization of decision-making with staff resistance against change (P>/05or P>/01). With correction of organizational structure, field for application of change can be provided. Source

The effects of elastic and inelastic electron-phonon interactions on current-voltage characteristic and tunnelling magnetoresistance (TMR) of Li@C59X (X = N, B) molecule that is coupled to two ferromagnetic electrodes was investigated using the non-equilibrium Green's function (NEGF) method. Our results by taking also into consideration spin degrees of freedom (excluding spin-mixing effects) indicate that the presence of inelastic electron-phonon interaction polaron formation increases current and shifts the TMR behaviour to higher values. Also, an increase of two orders of magnitude observed in current for Li@C59B compared to C60. © 2015 Taylor & Francis. Source

Introduction and aim: the prevalence of obsessive-compulsive disorders and depression increase prescription and consumption of serotonin reuptake medications. Therefore, the aim of this study is to investigate the side effects of clomipramine on testosterone, LH, FSH. 40 mature big male rats were divided into groups of control, sham, and experimental 1,2,3. these groups received 2.5,5,10 mg/kg doses ofclomipramine medicine by gavage method for 21 days.at the end, after drawing blood blood samples was used in order to measure serum concentration of LH.FSH and testosteronehormones, by radioimmunoassay. Data were analyzed by SPSS software (version of 18) and Duncan test. Results indicated a significant increase in concentration of LH and there was a significant decrease in the testosteroneconcentration.in experimental group 3 in the level of (p<0.001) thanother groups.no significant difference was also observed in the concentration of FSH. Clomipramine decreases testosterone secretion. Therefore, the use of this medicine is not recommended in the ages of pregnancy. Source

In this paper, the effect of modified clay on the mechanical efficiency of epoxy resin is examined. Studies by X ray diffraction and microscopic transient electron method show that modified clay distribution in polymer area is intercalated kind. Examination the results of mechanical tests shows that existence of modified clay in epoxy area increases pressure yield strength, tension module and nano composite fracture toughness in relate of pure epoxy. By microscopic examinations it is recognized too that the action of toughness growth of this kind of nano composite is due to crack deflection, formation of new surfaces and fracture of clay piles.

TiO2 nanocomposite films with different concentrations of TiO2 MT-150A nanoparticles were immobilized on glass substrates using a dip coating process. The crystalline structure and surface chemical state of nanocomposite film properties were examined by X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), respectively. The specific surface area and morphology of TiO2 MT-150A nanoparticles were evaluated by the BET method and Field Emission Scanning Electron Microscopy (FE-SEM). The photocatalytic activities of films were evaluated by the methyl orange decoloring rate. XPS measurements showed that the oxygen amount (%) was related to the film composition. The composite film with 10 g/L MT-150A loading yielded the highest amount of surface oxygen (26.82%) and TiO2 rutile showed the lowest amount of surface oxygen (13.67%) in the form of surface hydroxyl groups. The remaining oxygen was identified as lattice oxygen. In addition, the nanocomposite film with 10 g/L MT-150A loading yielded the highest photocatalytic activity. © 2010 Elsevier Ltd and Techna Group S.r.l. Source
