objectives: the aim of current study was to determine the effects of hata yoga training on dynamic and static balances of elderly women in mashhad. methods and materials: the present study enjoys the semi-experimental design. the statistical population of the study, which has been carried out in 2009, were elderly women of mashhad who were voluntarily invited to participate in the research. 29 ...

introduction: one of the main sections of warm up is stretching which the importance of them is static and dynamic stretching. the purpose of this study was to examine the effects of static and dynamic stretching within a pre-exercise warm-up on the static and dynamic in soccer players. materials and methods: eighteen physical education female students (height: 159.68 ± 5.94 cm; mass: 60.21 ± 5...

The balance assessment of biosphere material and energy flows those resulting from economic activity in the industrial region is carried out. analysis based on use stability indicators region's socio-ecological system. For activity, total input criterion was used, where consumed natural resources are reduced to a single value. It found that functioning sector operating fossil fuels created sign...

Csikszentmihalyi’s Flow theory states that a balance between challenge and skill leads to high engagement, overwhelming challenge leads to anxiety or frustration, and insufficient challenge leads to boredom. In this p aper, we test this theory within the context of student interaction with an intelligent tutoring system. Automated detectors of student affect and knowledge were developed, valida...

The paper discusses the processes that determine the parasitic heat generation and its distribution in the solid-state laser materials. It is inferred that the balance between the laser emission and heat generation is determined by the characteristics of the pumping system and by the partial efficiencies of the various steps of the flow of excitation between the energy levels of the laser mater...

A unified framework for analyzing the existence of ground states in wide classes of elastic complex bodies is presented here. The approach makes use of classical semicontinuity results, Sobolev mappinngs and Cartesian currents. Weak diffeomorphisms are used to represent macroscopic deformations. Sobolev maps and Cartesian currents describe the inner substructure of the material elements. Balanc...
