The effect of concentration and application method of chlormequat (cycocel), a plant growth retardant, on plant height and some other traits in Brassica oleracea cultivars 'Kamome White' and 'Nagoya Red' was assessed. Plant growth retardants are commonly applied to limit stem elongation and produce a more compact plant. The experiment was done as a factorial in randomized completely blocks design (RCBD) with four replications. Plants (40 days after transplanting) were sprayed and drenched with 500,1000 and 1500 mg I-1 cycocel. In each experiment, control untreated plants. Data were recorded the 60 and 90 days after transplanting. Based on analysis of variance (ANOVA), the effect of different treatments and their interaction on all traits was significant at 0.05 or 0.01 level of probability. Treatment of 1500 mg I-1 cycocel resulted in about 50 and 20% shorter plants than control plants, 60 and 90 days after transplant. The growth of Brassica oleracea cultivar 'Kamome White' and 'Nagoya Red' decreased with increased cycocel concentration. Foliar sprays of cycocel controlled plant height of both cultivars. Results indicated that the shortest plants (9.94 and 11.59 cm) were those sprayed with 1500 mg I-1 cycocel in cultivar'Kamome White' after 60 and 90 days, respectively. The largest number of leaves (33.94) and highest leaf diameter (9.39 cm) occurred in cv 'Nagoya Red', when drench was used. Maximum dry matter (14.31 %) accumulated in cv'Nagoya Red', treated with spray. © Triveni Enterprises, Lucknow (India).

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.

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.

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.

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.

The long term effects of Cu and Ni to water reserves were studied for the use of plants. The objective was to quantify m etals accum ulation in the soil profile and calculate material balances and metal removal efficiency as the metal loads increase Ni in the 0 to 3.5 m soil profile, with concentration increases of 0.25 to 1.35 mg/kg. Copper accumulated only in the 0 to 1.2 m top soil layer with concentration increase of 0.25 to 0.81 mg/kg. Sequential selective extraction showed Cu tended to oxides such as Fe and Zn oxides and organic nitrogen, and Ni only banded with organic matter. This amounts to the Cu and Ni applied during 10 years reported at the Khuzestan soil center. The low concentrations of Cu and Ni were effluent in the top soil and retained water in sub-soil. This led to attainment of excess water that crops needed in dry regions.

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.

This paper presents a hybrid genetic algorithm for assembly flow-shop scheduling problem with sequence-dependent setup and transportation times. The used objective function in this research consists of minimizing of the sum of total weighted squared tardiness, makespan, total weighted squared earliness and number of tardy job. Since the problem is NP-hard, we solved this problem by hybrid genetic algorithm.To validate the proposed model, the Lingo 8.0 software was used. Comparison between the results of the Lingo 8.0 and hybrid genetic algorithm shows that in larger problems (if >10, where is the number of jobs) the results obtained by Lingo do not have adequate efficiency and cannot be compared with the proposed hybrid genetic algorithm in terms of computational time and deviation from the minimum objective function.Test results are provided for a wide range of problem instances.
