Sheikh Bahaei University or SHBU also known as Sheikh Bahaei University and SHBU,was established by virtue of the 1994 Law of non–governmental and non-profitable universities and institutions through the efforts of ten professors from the University of Isfahan.Sheikh Bahaei University is governed according to educational regulations of the High Council of Cultural Revolution and the Ministry of Science, Research and Technology, the latter endorsing its credential degrees. Like many other universities and institutes affiliated with the Ministry, it admits students through the National Entrance Examination held by the Iranian Educational Testing Organization. The students are therefore to comply with the rules and regulations set by the mentioned Council and Ministry in all aspects of their education including matters related to student affairs, discipline, tuition and fees.

In this paper, we obtain several new generalized KKM-type theorems under a new coercivity condition and the condition of intersectionally closedness which improves condition of transfer closedness. As applications, we obtain new versions of equilibrium problem, minimax inequality, coincidence theorem, fixed point theorem and an existence theorem for an 1-person game. © 2012 Springer Science+Business Media, LLC.

In this paper, we consider different kinds of generalized vector variational-like inequality problems and a vector optimization problem. We establish some relationships between the solutions of generalized Minty vector variational-like inequality problem and an efficient solution of a vector optimization problem.We define a perturbed generalized Stampacchia vector variational-like inequality problem and discuss its relation with generalized weak Minty vector variational-like inequality problem. We establish some existence results for solutions of our generalized vector variational-like inequality problems. © Springer Science+Business Media, LLC. 2011.

Chemical exchange saturation transfer (CEST) is a new mechanism of contrast generation in magnetic resonance imaging (MRI) which differentiates molecule biomarkers via chemical shift. CEST MRI contrast mechanism is complex and depends on radio frequency (RF) pulses used in experimental conditions. To find the optimal RF pulse, numerical solutions of Bloch-McConnell equations may be used. The purpose of this work is to compare the effects of different RF pulses on the CEST phenomenon. First, a two-pool exchange model for CEST in MRI is used. Z-spectra and signal calculations for the two-pool model have been carried out for some RF pulses. Efficiency of both continuous and binomial RF pulses is investigated by calculating three parameters, namely: CEST image contrast, flip angle and specific absorption ratio (SAR). The contrast of CEST image is considered proportional to amount of saturation. As a binomial RF pulse, WALTZ-16* demonstrates a good efficiency, but generates some unwanted direct saturations. On the other hand, continuous RF pulses do not create any unwanted direct saturation, but have less efficiency. © 2012 IEEE.

Some properties of α-weakly preinvex and pseudoinvex functions via Clarke-Rockafellar and limiting subdifferentials are obtained. Furthermore, the equivalence between vector variational-like inequalities and vector optimization problems are studied under pseudoinvexity condition. © 2011 Springer Science+Business Media, LLC.

The present study was carried out to scrutinize the possibility and extent of transfer at the level of concepts in parity and internal content based on Jarvis’ (2007) framework among Iranian EFL learners having the following in focus: concepts in Persian that do not have counterparts in English, concepts that are broader than a corresponding concept in English or vice versa, and concepts in Persian and English that seem to be broadly equivalent but are still different. Also, it investigated to examine the role of the two learner-based variables of language proficiency and age in Iranian EFL learners’ possible conceptual transfer. To serve the purpose, the data were collected from 100 Iranian learners (70 females, 30 males) studying English as a foreign language in an English Language School in Mobarakeh, Isfahan. With the data being submitted to statistical analyses, the findings revealed significant cases of conceptual transfer from Persian to English. It was also noticed that the participants’ level of English proficiency played a significant role in their transfer of concepts but their age did not. © 2012, Australian International Academic Centre PTY LTD.
