1. RELATIONSHIP BETWEEN SOCIAL CAPITAL AND ORGANIZATIONAL ENTREPRENEURSHIP
by Babak Jamshidinavid, Mojtaba Chavoshani & Farzad Parse
Abstract

Nowadays, according to the extent and variety of changes inflicted on the body of the organizations, they have found to deal with the changes that so have faced, They Should be associated with the new compounds of their existing resources to provide new competitive advantages and this is why the importance of creative staffing and innovative human resources and the entrepreneurs of organization have become more prominent. Since university education as the main custodians of HR professionals play a vital role in society, entrepreneurship consideration in this matter will help the organization to develop better and in the meantime, the social capital and pay special attention to it, is a crucial factor in achieving organizational goals and in order to promote and facilitate the organization of programs is important which the processes of innovation, creativity and collective learning are affected by it , and it's easy to achieve .This study is about relationship between the social capita and entrepreneurship in Islamic Azad University of Kermanshah. Staff and faculty members of Islamic Azad University of Kermanshah have formed Statistical Society in this study. And among them, 210 persons are selected as the study sample. Analysis of the research model and hypotheses testing were performed by using structural equation approach , as well as, confirmatory factor analysis and Path analysis diagram was performed by using  LISREL software , and  the results showed  that there is a significant relationship between social capital (Structural, cognitive and relational) and entrepreneurship.

2. CONTRIBUTION TO IMPROVING THE PERFORMANCE COEFFICIENT OF A SOLAR ABSORPTION REFRIGERATION SYSTEM

by M. Benramdane, MEA. Ghernaouet & S. Abboudi

Abstract

It is easy to notice lately, the significant growth that the energy market, which opens the doors to a race for new energy sources and new methods for obtaining the benefit of energy. It is in the same vein as some industrial and research laboratories with an interest environment increasingly growing development of absorption chillers that have many advantages.

The absorption refrigeration systems using ammonia-water couple now become a promising solution for cooling due to their many advantages. These systems use greener refrigerants to the environment. They also have the advantage of using a free source of heat and clean by coupling with a solar heat source.

The objective of this work is to study a refrigeration loop absorption using the ammonia-water pair purpose of determining its performance and suggest improvements. This improvement in the coefficient of performance "COP" is based on changes to the system to absorption itself. Our approach is to increase the number of boilers and absorbers (three boilers, condenser, evaporator and two absorbers). The modifications brought us the following advantages: the possibility of operating with temperatures vary around 70 °C panels that require less costly simple plans and elimination of the distillation column which is explained by the reduction in the overall cost of the facility with improved COP.

3. COMPARISON OF THE NONLINEAR OPTICAL PROPERTIES OF PLATINUM NANOPARTICLES IN BOTH PULSED AND CONTINUOUS REGIME
by M. Eslamifar
Abstract

 

The nonlinear properties of platinum nanoparticles (ptNPs) in the aqueous solution of sodium dodecyl sulfate (SDS) are investigated under irradiation of a continuous wave (CW) laser and nanosecond pulse laser at the wavelength of 532 nm. These properties are studied using Z-scan technique. In this technique transmittance of the laser beam by the sample is measured. The closed Z-scan measurements reveal thermal contribution for the nonlinear refractive index of the platinum nanoparticles in the CW regime and the saturable absorption is observed using the open aperture Z-scan method in the pulsed regime. It will be shown that the thermal thin lens model is in excellent agreement with the experimental results of the sample. A fit has allowed extracting the value of nonlinear refractive index to be -1.08 10-8 cm2/W. The saturable absorption is analyzed using a phenomenological model based on nonlinear absorption and saturation intensity.
