Background and Aim: Changes in lower extremity Alignment are considered as a risk factor for the injuries in this area together with Q Angle. The purpose of the present study was to examine the relationship and affecting anatomical factors of lower extremity Alignment on the Q Angle.Materials and Methods: A total of 120 male students from Tehran University participated in the study and their lower extremity Alignments were investigated in these factors: hip anteversion, internal and external rotation of the hip, valgus and varus of knee, hyperextension of the knee, tibia rotation, tibiavara, and arch index.Results: The results showed that the variables of plantar arch index, varus and valgus of knee, hip anteversion, and tibial torsion had maximum effect on the predicted value of the Q Angle (p£0.05) and the most influence was found to be respectively related to plantar arch index, anteversion of hip, tibial torsion, and varus and valgus of knee.Conclusion: The results showed that the changes in the lower extremity anatomical Alignment can affect the amount of Q Angle. Among the variables studied, the plantar arch index was noted to have the greatest impact due to the influence of the three-point constituent of this Angle. Changes in this Angle can put the person at the risk of various injuries in the segments of the lower limb.

In this paper the planar Alignment is considered by using numerical calculations, the effect of the thickness of the slab on the threshold field (Bc) and effect of exerted magnetic field on the maximum distortion (qm) in the center of the sample have been shown. Finally, changes of Angle Alignment of nematic molecules (q) for a narrow slab in a magnetic field are investigated.

Introduction: In the current research, it has been tried to qualitatively study all kinds of policies and measures necessary for Alignment between teacher preparation programs and democratic social education competencies under the model of teacher education curricula, which include: direct (official) curriculum, Indirect curriculum, informal curriculum (implicit) and unstructured curriculum (hidden) should be identified in the educational system. Method: Qualitative approach and phenomenological method were used in this research. The field of research is Farhangian University of Hormozgan and the participants are  13  lecturers of this university. The sampling method is a combination of convenience and snowball sampling. The research tool was a semi-structured interview. The information was analyzed using thematic analysis method and then using MAXQDA software... Result: The information was analyzed using the theme analysis method and then using MAXQDA software in the form of 2  overarching themes, 8 organizing themes and 25  basic themes. The results of this research showed the basic policies and measures for teacher preparation programs, in the form of two components, strategies and solutions of teacher training curricula, separated by curricula (formal, informal, informal, unstructured curriculum) and with the goal of preparing The formation of teachers has been identified in the educational system to realize the competencies of democratic social education. Conclusion: Therefore, examining the opportunities, facilities, and resources available to achieve these actions should be on the agenda of decision makers and educational planners. It is necessary to pay special attention to the strategies and solutions of teacher training curricula.

The present paper investigates the effect of changes in wheel primary Angles such as Camber and Toe Angles on the fatigue life of vehicle steering knuckle under multi-input random non-proportional 3D stress components. In order to develop real loading conditions for the steering knuckle, the localizing equivalent road as a combination of some rough roads (ISO road classification B-F for highway out of town, urban highway, urban asphalt, soil road, and flagstone, respectively) based on statistical data collected from different cities by utilizing a general questionnaire including road type and vehicle velocity was considered. Then, the various actual load histories obtained through multi-body dynamics analysis of a full vehicle model were applied on several points of the component. The fatigue life of steering knuckle was predicted by using some prominent multi-axial fatigue criteria for non-proportional loading, rain-flow cycle counting algorithm, and Palmgren-Miner damage accumulation rule. Finally, the effect of different values of wheel Angles on the fatigue life of the steering knuckle was examined. The results showed that the highest and lowest fatigue life of steering knuckle are related to the values of 2 positive and negative degrees of camber Angle, respectively. The stress level is reduced in the various equivalent load histories by changing the toe Angle to 0. 2 negative, resulting in an increase in the fatigue life of steering knuckle.

The present study evaluated the performance of a novel solar heating system. A linear Fresnel lens was used to concentrate the heat in this system. Pre-experimentation tested the performance of the system at 5 Alignment Angles and 5 slope Angles. The data was used to evaluate the performance of the system in December 2014 at 6 flow rates (100, 200, 300, 400, 600, and 800 ml. min-1). In these experiments, solar radiation, wind velocity, temperature of fluid in collector, ambient temperature, and ambient relative humidity were recorded. The results demonstrated that the best performance of the system was at a 300 ml. min-1 flow rate, due south orientation, and with monthly adjustment of the slope of the lens. The correlation between the parameters indicated that at different flow rates, the effect of solar radiation on the temperature of the ambient air, heat-absorber pipe, output fluid, and input fluid were 0. 91, 0. 895, 0. 86 and 0. 84, respectively.

In this paper, a step-by-step laboratory procedure for performing a satellite's payload’s Alignment measurement is presented. Four highly accurate theodolites are used along with two or more Alignment corner cube to accurately extract the final attitude. Theodolites are arranged around the satellite in such a way that they have a clear direct view of the Alignment cubes mounted on the payload and the satellite. Two theodolites should point to the payload’s Alignment cube and the other two theodolites must point to the satellite’s Alignment cube. Each theodolite must see at least one other theodolite, directly. Finally, by forming the coordinates systems of the payload and satellite in the theodolites coordinate system along with using the coordinate transfer matrices, the payload Alignment correction matrix will be extracted in detail. The total method accuracy is within the order of few arcseconds.
