Study of privatization effects on resources productivity by productivity by using data envelopment model and MalmQuist index: A case study for branches of Kermanshah province Mellat Bank
Economic effects of human beings have been always focused on how to obtain the best results b using the least possibilities and factors available, such tendency can be called "attainment of higher efficiency and productivity". Productivity is a comprehensive concept encompassing efficiency an increase in which is taken into account by politic and economic authorities continuously in order to promote standard of living of, welfare of, and relaxation and peace of people. Some consider survival and persistence of a politico-economic system dependent on productivity. One way to increase productivity is privatization and free trade. Present research focuses on effects of these 2 variables on each other. Subject of this research is to study effects of privatization on total productivity of production factors in in Mellat Bank and its aim is to analyze productivity after Mellat Bank was privatized in order for resulting outcomes to create clearer outlook and wider perspective in front of managers. Considering research aim and subject, this research used descriptive-analytical method. In present research, inputs and outputs of 48 Mellat Bank of Kermanshah province were studied in 2 time intervals: one related to pre-privatization time (2005-2007) and other to post-privatization time (2009-2011) of Mellat Bank. This research inputs include personnel, administrative, and operational costs while outputs include volumes of deposits, facilities, and services provided. Data was analyzed by using MalmQuist index and data coverage analysis with EMS and GAMS software. Then, hypotheses were tested by SPSS software. Research results indicate that, following privatization, total productivity index and human force productivity increased significantly and it was found that technological changes relate directly to the level of productivity so that enhanced technology level can increase productivity level.

Synthesis and characterization of chitosan based graft co polymer: an efficient adsorbent for dyeing industry waste water
N- Maleilated chitosan was synthesized by reaction of chitosan with maleic anhydride (MA) in N, N-dimethyl formamide. N-Maleilated chitosan – g – (methyl methacrylate) co-polymer was prepared via free radical polymerization using ceric ammonium nitrate (CAN) as the initiator. The effect of polymerization variables including initiator concentration, monomer concentration and reaction temperature on grafting percentage were studied. It was found that the grafting yield and grafting efficiency were increased with increasing the polymerization variables and then decreased. The grafting was maximum at 1.6g of initiator (CAN), 2g of the monomer (Methyl methacrylate) at 700c. The co-polymer obtained was confirmed by FTIR, XRD, TGA, DSC analysis. This graft co-polymer was used as an adsorbent in dye effluent treatment. It was more efficient than parent chitosan. Equilibrium sorption experiments were carried out. The experimental data was successfully fitted to the Langmuir adsorption isotherm.

Synthesis, characterization and antibacterial studies of nickel (II) mixed ligand complexes of dithiocarbamate ligands with Schiff base
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.

Temporal analysis of wheat yield and climatic trends in Pakistan
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 Role of Press TV Channel and its Media Functions in Reflecting Political Events in Iran
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.

Thermodynamic Parameters, Electrical Conductivity and Spectrophotometric Measurements of Mn 2+, Co2+, Ni2+Cu2+, Zn2+, Cd2+, and Fe3+-Complexes with Some Schiff Base Hydrazones Containing Quinoline Moiety
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.
