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.

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.

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.
