Nickel (II) mixed chelates of Schiff base derived from salicylaldehyde and aniline with various dithiocarbamate ligands have been characterized by metal analysis, microbial activity, solubility, infrared and electronic spectral measurements. The compounds were generally insoluble in water and soluble in some solvents. The metal analysis gave values close to the expected percentage metal values confirming the coordination of the nickel metal in the complexes. The interpretation of the infrared spectra of the complexes showed that the two uninegative ligands coordinate to the metal ions in their complexes in a bidentate mode, the dithiocarbamate ligands binding through both sulphur atom and the Schiff base through the azomethine nitrogen and phenolic oxygen. The electronic spectra revealed that the nickel complexes are typical of square planar as evidenced by the presence of two d-d absorption bands. The synthesized compounds showed moderate to high antibacterial activity against the test bacteria and can be effective as antibiotics.

During the recent decade, the anthropogenic activities have become dominating factor towards the problem of climate variability and change. This climate variability has become the centre of many scientific studies. The objective of this paper was to investigate the total wheat yield during the time period of 1989-2009 and the overall impact of climate on the wheat yield in the provinces of Pakistan. The key meteorological variables that influenced the wheat yield were identified, the correlation and regression functions between climate relevant wheat yield and these variables were established. The correlation analysis revealed a significant relationship between wheat yield and climatic variable and regression analysis revealed that high level of variance in wheat production could be explained by climatic parameters under study. The findings of the research suggested an intensification of research as well as the appropriate measures at raising wheat yields.

The purpose of the present research was to study the effect of therapeutic horseback riding on repetitive behaviors of children with autism spectrum disorders. It was quasi experimental with one group Pre and Post Test design. The samples were 6 children with autism spectrum disorders selected through available method in a special education center for autistic children in Shiraz, Iran. All the participants had pre-test and then therapeutic horseback riding intervention for one month (consisting of two 45 minute session of riding per week) and finally post-test was administered. Bodfish et al (2002) revised repetitive behaviors scale was used to assess children’s repetitive behaviors. Paired-samples T Test was utilized to analyze the data. The results showed that therapeutic horseback riding decreases the repetitive behaviors of children with autism spectrum disorders significantly. It can be concluded that therapeutic horseback riding has a positive effect on repetitive behaviors improvement.

The present paper intends to bring forward the impact of T.V programs on Indian College Students’ behavior. The progress of the human civilization is demarcated with district eras; these eras have been characterized by technological advances and innovation that changed the human life. The latest innovation to multiple satellite TV channels into the drawing of urban Indian is greatly determining the TV viewing behavior. The present study is conducted with the following objectives: 1.To find out the TV viewing behavior of Arts College Students in terms of various TV channels and types of programs . 2. To assess the perception of college youth regarding to TV programs and their influences both positive and negative. 3. To find out whether there is any association between certain demographic variables pertaining to College youth and their perception of TV programs. Keeping these objectives of the studying in view, the following questions have been formulated for variation: 1.Are the respondents, (College Students of Art College) likely to perceive the foreign program as source of negative influences? 2.Do the respondents watch Foreign Programs more than Indian programs? 3.Do the respondents watch documentaries less than the other type of films? The Sample is 120 Native Students from the Art College of Osmania University, (Hyderabad. India) which selected randomly from different departments. Keeping the study objectives in view, a questionnaire in English was developed pretested.

The purpose of this study is the review of the relationship between organizational trust and knowledge management in the national company of refining and distribution of the oil production in Kermanshah – Iran. This research is on the basis of the descriptive type, and the questionnaires are used in it. Aloonen et al., (2008). Questionnaires are used for organizational trust and for knowledge management evaluation is the questionnaires of Proset et al., Capacity of statistical society consist of 270 employee of the national company on the basis of the class accidental sampling among them, some of them have selected as a statistical sample and finally, 134 questioners have collected. Kolmogorov -Simonov test was used for the determining of the normality collected data, and to confirm the results of it. Hypothesis of the research were put in test container with spearman conjunction test. Results show meaning full and positive conjunction between trust and knowledge management. That is as trust of employees about their organization, increases; they should show much knowledge management.

This study was to analyze the content of the news reported in network Press TV. It studied the reflection of political events in this network. The research was performed for highlighting and emphasizing the political functions of the media and political communication using content analysis. The choice of network news, news related to political events that represent the policy of the media network, is taken into consideration. The study samples included news about the political events in Press TV network. In this study, 141 reports were selected for content analysis in terms of indicators such as induced bias or impartiality, the value of news, news items, and other news sources were evaluated. According to the results, most of the news, with only one-sided and agreeing point of view in covering news related to Iran, reflected in a few cases. The viewpoints were one-sided in favor, and opposite views were covered too. Merely the reflection of the agreeing views will manifest the orientation of the news and shows the network as biased. Thus, it is suggested to avoid declining opposite views and to cover them in a proffessional way. This will not only make audience rely more on the news, but also will help the reports to be more effective and thus, it will be easier for the audience to accept the main theme of the network.

A new hydrazone Schiff base consisting of 7-chloro-4-(o-hydroxy benzilidenehydrazo) quinoline, with metal complexes of some divalent metal ions, Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II), and Cd(II) were investigated Conduct metrically and thermodynamically. We have used molar ratio method to determine the stoichiometric of the formed complexes, The results obtained confirmed the formation of 1:1 and 1:2, M: L complexes. In order to get information about the composition of complexes electrical conductivity were determined. The standard thermodynamic parameters viz. ?G, ?H and ?S, for the proton-ligand and the stepwise metal-ligand complexesluated. Thermodynamic functions were analyzed in terms of the electrostatic (el) and non-electrostatic (cratic, c) components. ?Hc was found to be linearly correlated with the acceptor number of the metal ion (ANM), and ?H el was linearly correlated with the ionic radii of the metal ion. The calculated values for ?Go, ?Ho and ?So concluded that the complexion process processed spontaneously. Spectrophotometric measurements of Co (II), Ni(II) complexes obeyed Beer's law up to certain values, 6.6 x 103, 8.0x103 dm3mol-1cm-1, respectively, indicating that the ligand HL could be used to detect Co(II) and Ni(II) in such concentrations. The study was performed also for Fe (III)-complexes.

Topology is a branch of geometry concerned with the properties remains unchanged when the figure is deformed. The significance of topology is which will help to develop light weight components which are used in manufacturing of two wheeler carts, etc., the result is we get better automobile fuel efficiency. This in turn results to energy conservation and global environmental preservation. In industries several attempts are made to produce lightweight designs. In order to manufacture light weight component our first step is to decrease the weight of the wheel rim. The wheel is designed using CATIA and Imported CATIA 3D Model into Altair Hyper Mesh V13 for doing Pre-processing and ALTAIR Optistruct Software for doing optimization and structural analysis of the wheel rim. The aim of this work is to develop an optimization procedure in order to reduce the weight of rim component. The focus of this project has been the weight reduction of an aluminium wheel by means of a topology analysis.

Translating for children has always been crucial perturbation for professional and non-professional translators as Sprachmittlers. This is owing to conjectural vulnerability of this cohort of people in conditions of their world of childhood. When we embark on translating for children, we should bear in mind that a text is not a stable/durable object: it brings along a different response at every reading. Therefore, we are dealing with various readings and also a wide range of interpretations. In this respect, we bring out Skopos Paradigm as for the fulfillment of our intention in translating for children since this paradigm parks more fully-grown the pree of purpose and situation of the clientele (e.g. children). Whatever a story or written form is, when translating for this intended group of people, what matters is the maintenance of function-aim-among possible yet pertained interpretations.

In this work, we make use of the well known product rule and Leibnitz’s theorem to generate a new method which can be used to obtain the higher order derivatives of any functions which depends on four variables. The new method does not require the knowledge of the preceding derivative before obtaining the succeeding ones.
