in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...

wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...

Background and purpose: Today, most organizations have recognized the value of their invisible assets and seek multiple methods to use them efficiently. One of these invisible assets is knowledge and knowledge management is a process of creating value from knowledge implementation. Execution of knowledge management requires paying attention to important factors such as organizational culture a...

Introduction: Knowledge management as a new subject has created a new approach to facilitating education and research in the higher education system. University graduates need to enter the world with the tools to play a role before they go to work, which is considered imperative in knowledge management. The purpose of this study was to survey the effectiveness of the PhD. curriculum to create k...

The capability approach has been used for nearly two decades as a holistic framework for guiding qualitative inquiries on equity in higher education. Despite significant research in this area, the scope of the basic capabilities needed for the realization of equity in access to higher education and during university education has not yet been clarified, and the extent of the factors influencing...

we show that when both sources ( lepton flavor violation sources and cp-violating phases) are present, the electric dipole moment of the electron, $d_e$, receives a contribution from the phase of the trilinear $a$-term of staus, $phi_{a_ au}$. for $phi_{a_ au}=pi/2$, the value of $d_e$, depending on the ratios of the lfv mass elements, can range between zero and three orders of magnitude a...
