in new management approaches, in the organizations with inflexible structure, existing of red tapes and interruptions caused by limitations and also non-compliance with environmental changes, create demotivation among staff. with regard to the influence of job motivational potential and its relationship to the type of organizational structure( enabling and dissuasive), the goal of this research...
In many studies concerning wire heating during MR imaging, a "resonant wire length" that maximizes RF heating is determined. This may lead to the nonintuitive conclusion that adding more wire, so as to avoid this resonant length, will actually improve heating safety. Through a theoretical analysis using the method of moments, we show that this behavior depends on the phase distribution of the R...
A. K. Rutz, S. Ryf, G. Crelier, S. Kozerke, P. Boesiger Institute for Biomedical Engineering, University and ETH, Zurich, Switzerland Introduction: Myocardial tagging such as CSPAMM [1] combined with harmonic phase-analysis (HARP) [2] is a powerful method to quantify myocardial motion of healthy and diseased hearts. CSPAMM data are typically acquired using a phased array coil. In order to achie...
This paper studies fault-tolerant operation of multipole single-phase switched reluctance generators (SRG’s), in particular, an 8/8-pole switched reluctance machine. The multipole single-phase SRG system is advantageous for reduced cost and higher efficiency compared to polyphase equivalents. However, using the classical phase-leg topology, a phase fault may prevent generating operation complet...
abstract i the purpose of this study was to launch a thorough investigation concerning the possibility of differing orientations to the writing proficiency construct by native and non-native english speaking teacher raters. it mainly revolved around the international english language testing system (ielts) that is widely administered and employed as a measure of general proficiency in englis...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
here, we report analysis of in vitro and in vivo drug release from an in situ formulation consisting of triamcinolone acetonide (tr) and poly(d,l-lactide-co-glycolide) (plga) and the additives glycofurol and hydroxyapatite nanoparticles (ha). we found that these additives enhanced drug release rate. we used the taguchi method to predict optimum formulation variables to minimise the initial burs...
Overcoming Coil Phase Effects in Highly Accelerated Imaging with a Dedicated Fourth Gradient Channel
Introduction: Magnetic Resonance Microscopy (MRM) has become an important tool for in-vivo microscopy and in-vitro/exvivo histology [1,2]. One challenge is that very small RF coils are used to obtain high signal-to-noise ratio in small voxel sizes. These small coils limit the field-of-view, necessitating the use of arrays or multiple studies. In this abstract, the extension of our previous work...
abstract foreign and iranian cultures are far distinct in the constraints imposed on writing and translating for children, since the iranian literary system is mainly concerned with cultural and religious instructions which lead to manipulation of translated texts. this study sought to identify the cultural and social constraints and norms which determined the strategies applied in the transl...
acknowledge the importance of e-commerce to their countries and to survival of their businesses and in creating and encouraging an atmosphere for the wide adoption and success of e-commerce in the long term. the investment for implementing e-commerce in the public sector is one of the areas which is focused in government‘s action plan for cross-disciplinary it development and e-readiness in go...
