in chapter one we will describe definitions and preliminary results to provide the global context of our own results to be presented in detail in the subsequent chapters in chapter two we consider degree-one maps of the circle and we study their rotation set. our main result in this chapter says that if the map is topologically mixing then its rotation interval is nontrivial (that is, not reduc...

Background & Aims: Previous studies have stated that the scapulohumeral rhythm dysfunction can make a person prone to glenohumeral joint pathologies. The purpose of this study was to survey symmetric resting scapular posture and scapulohumeral rhythm ratio between dominant and non-dominant shoulders in elderly subjects in different humeral abduction angles. Materials & Methods: Thirty-five hea...

this research study aimed to investigate the relationship between field-dependence/independence cognitive style and vocabulary learning strategies among iranian efl learners. ninety participants majoring in english translation at arak university were chosen. the participants were classified into two groups of field-dependent and independent based on the results of group embedded figure test (ge...

 In this paper, we calculate the spin-dependent conductance of ferromagnetic quantum wire in the presence of one or two defects by using Green's function method at the tight-binding approach. We study the effect of rotation of defect magnetic moment on the system conductance. The results show that in the magnetic wire, independent of existence or absence of defect, the allowed energy region shi...
