 This research aimed to visualize the growth of science development, scientific production, citation frequency of documents, highly cited documents, top authors, widely published journals, and significant subject categories related to documents in the field of social performance of public libraries among the countries with the most publications. Additionally, the research aim was to prepare a cooperation map and evaluate scientific productions in this field.

 According to the purpose of the research, the current research was of the scientometric and applied research kind, and in terms of data collection, it was a descriptive-analytical research type. This research implemented a quantitative approach and scientific indicators such as the centrality index, vocabulary co-occurrence analysis, and co-authorship networks. The data collected from the articles indexed in this database، after retrieving 278 records related to the research, data was analyzed based on the objectives of the research. To draw the networks and maps used in the present study، as well as data analysis، the software of HistCite، Gephi، Node XL, and VOSwiever were used.

 Findings show that scientific productions and the number of citations received in this field during the years under review had generally top and down. Highly cited articles were published in journals in the field of information science and librarianship between 2007 and 2016. All articles in this field were written by 640 authors. The highest collaboration was among 23 authors with at least two collaborations. The rest of the authors contributed to only one work whom their affiliation were the University of Pennsylvania. The Australian National University has the highest number of intermediate centers. The order of universities also varies according to the degree of centrality index or number of collaborations. The highest correlation between the two subjects is related to the subjects of public libraries and information services with a strength of 5. After that, the highest correlation is between the subjects of social media and public libraries with a correlation strength of 4. Social acceptance with public libraries with a correlation strength of 4 and public libraries with web 2 with a correlation strength of 4.

 The most common collaborations in the production of works in the field of social performance of public libraries have been between the United Kingdom and the United States، China with the United States، Australia with the United States، and the United Kingdom with Scotland، respectively. The largest joint venture between the University of Ghana with Kuwait University of Science and Technology، and the University of Illinois with Drexel University، and the rest of the universities had a joint venture. The highest percentage of international collaboration belongs to Australia and the lowest percentage of international collaboration belongs to the United States. With a deeper study of the mentioned cases, one can better understand the limitations and challenges related to the social performance of public libraries in our country and try to fix or improve it. According to the obtained results, it is suggested that Iranian researchers enter more in this field and have scientific cooperation with the authors of other countries, scientific and research centers support and encourage Iranian writers to collaborate with writers from other countries. Particularly, Asian countries should cooperate to gain a greater share in scientific cooperation between countries.

In present study kinetics and equilibrium isotherms models were used in static / batch technique to demonstrate phenomena involving in the process of Rhenium ions uptake on Purolite A170 ionite. In order to realize the adsorption mechanism, four widely used adsorption isotherm models were subjected in detail. The results suggested that in general all models applied generate a satisfactory fit on laboratory data but both Freundlich and D-R isotherm models showed the selectivity coefficient (R2) more than 0.99, and so they can be used to track the equilibrium of the process. Also, in current conditions the maximum monolayer coverage capacities (qm) from the Langmuir isotherm was calculated to be 166.67 mg/g. Modeling of the batch kinetic adsorption was performed by pseudo first order, pseudo second order, Elovich and Intraparticle diffusion equations. The analysis of the results showed that the pseudo second order model can define the adsorption rate properly than others.

several researches have referred to relationship between Schemas as the core of human beliefs and personality styles and characteristics. According to this could we predict resiliency based on the schemas?

This study was conducted with the aim of predicting the resiliency based on early maladaptive schemas and a five-factor model of personality in nurses working in governmental hospitals in Tehran.

The research method is descriptive and correlational. In this study 200 persons were selected according to available sampling method. In order to analyze the data, inferential statistics including Multiple Regression Analysis and Pearson Correlation Coefficient test were used. The tool used to measure variables was the schema questionnaire-short form (J. E. Young, 1998), Neo short form questionnaire (2004), and Conner & Davidson's resiliency questionnaire (2003).

Using Multiple Regression Analysis and Pearson Correlation Coefficient, relationship between neuroticism variables and early maladaptive schemas with resiliency is negative and significant (P<0/05) and the relationship between extroversion, openness to experience and responsibility with resiliency is positive and significant (P<0/05).

The results showed that with increasing neuroticism and early maladaptive schemas, resiliency is reduced and with increasing extraversion, openness to experience and responsibility, resiliency is increased. The results also showed that the early maladaptive schemas had the greatest impact on resiliency.

Assisted leaching of copper from Sarcheshmeh chalcopyrite concentrate was studied. The Effect of addition of sodium peroxodisulfate was investigated. The results showed that at pH 2, in the absence of ferric ion, addition of peroxodisulfate up to 5 g/l increases copper dissolution 14% while more addition to 7.5 g/l has negative effect and decreases the copper dissolution. In the absence of additive, an optimum concentration exists for ferric ion. When 10 g/l ion ferric used, addition of peroxodisulfate up to 10 g/l increases copper dissolution while more addition ceases the leaching. About 40% of copper was dissolved after 24 hr at 70 C while the concentrations of ferric ion and peroxodisulfate was 10 g/l.

Gestational diabetes is a type of diabetes that first diagnosed during pregnancy. Its prevalence has been reported between 1. 3% to 8. 9% in Iran. This study was performed to compare the effect of nutritional interventions with educational methods and without education، and also comparing the behavioral change models education based to control gestational diabetes.

Electronic search of databases was performed using the keywords in English and Persian from SID، Iran Medex، PubMed/MEDLINE، and ScienceDirect. Selected studies were divided into 3 categories including: Diets، diet education based on theories and behavioral change model and diet education without model. The comparison were made between groups.

The results indicated that high-fiber diet on glycemic control was effective in all studies. Social support، self-efficacy and receive feedback influenced on adopting healthy behaviors and group training was more effective than face to face training.

Planning and organizing the appropriate and proper training are necessary to audience and using health education models and theories were more effective than conventional training.
