Pronation distortion syndrome is one of the most common abnormalities in the body that causes distortions in the structures of the skeletal structures of the lower extremities and increases postural sways. The purpose of this study was to determine the effect of 12-week corrective exercises on postural sways in male students with pronation distortion syndrome. In this semi experimental research...
Abstract. In this paper we define and verify a subclass of harmonic univalent functions involving the argument of complex-value functions of the form f = h + ¯g and investigate some properties of this subclass e.g. necessary and sufficient coefficient bounds, extreme points, distortion bounds and Hadamard product.Abstract. In this paper we define and verify a subclass of harmonic univalent func...
Studies on welding process of Aluminium weldments shows that post-weld residual stress and deformation are influential on structure efficiency and there are different variable which affect these stresses and deformation. In this study the effect of geometrical variables and welding sequence on residual stresses and deformation in Aluminium H321 have investigated by the finite element software A...
in this paper we obtain coefficient characterization, extreme points and distortion bounds for the classes of harmonic $p-$valent functions defined by certain modified operator. some of our results improve and generalize previously known results.
objectives: multiple sclerosis is the most prevalent central nervous system diseases thatdue to being chronic, frequent recurrence, uncertainty about its progress, and disability, can lead to various distresses as well as demoralization . rehabilitation method based on cognitive-existential therapy is an integratedapproach which can help to decrease demoralization syndrome in these patients. th...
An approach to the measurement of distortion in hearing aids is presented. Distortion is first defined in general terms. The technique is then applied to the specific problem of predicting the detectability of non-linear distortion. Distortion indices have been obtained for two common, but very different forms of distortion: peak clipping (common to most conventional hearing aids); and, quantiz...
The increase in the number of pulses in multipulse rectifiers leads to a reduction in harmonic current distortion. But this increase in the number of pulses leads to an increase in kVA, cost, and complexity of the multi-pulse rectifiers. As a result, in industrial applications, 12-pulse rectifiers are mainly used due to their lightweight, simple transformers, and low kVA rate, and low cost. The...
Objectives: Pronation distortion syndrome is one of the common physical deformities, that causes distortions in the skeletal structures of the feet. The current study aimed to determine the effects of 12 weeks of systematic and functional corrective exercises on the body posture of students with pronation distortion syndrome. Methods: In this quasi-experimental study, 30 volunteers suffering ...
