The study employed a two-dimensional (2D) space with multibody dynamics as the physics to simulate dynamic behaviour of intermeshing gears. Both gear teeth and body were principal stress strain well Von Mises system. A pair meshing examined from pinion other for accurate contact stress-strain simulation. validity proposed simulation was verified surface stress, strain, elastic total displacemen...

Drought stress is one of the serious problems that restricted agronomic plant production worldwide. In molecular level, the harmful effect of drought stress is mostly caused by producing of large amount of reactive oxygen species (ROS). Catalase and Metallothionein genes have a crucial role to mope the hydrogen peroxide (H2O2) resulting reducing oxidative damage. In this research the gene expre...

Repeated stress can trigger a range of psychiatric disorders, including anxiety. The propensity to develop abnormal behaviors after repeated stress is related to the severity, frequency and number of stressors. However, the pattern of stress exposure may contribute to the impact of stress. In addition, the anxiogenic nature of repeated stress exposure can be moderated by the degree of coping th...

In this essay a new theory of stress and linguistic rhythm will be elaborated, based on the proposals of Liberman (1975).' It will be argued that certain features of prosodic systems like that of English, in particular the phenomenon of "stress subordination", are not to be referred primarily to the properties of individual segments (or syllables), but rather reflect a hierarchical rhythmic str...

In this study, ANSYS finite element software is used to simulate the temperature and stress field in the laser powder deposition process. The model is used to determine the effect of the deposition pattern on the final stress distribution. Four deposition patterns are defined to cover the same area: long bead, short bead, spiral in, and spiral out. The results show that the deposition pattern s...

one of the most important issues that faced cities in developing countries with a crisis is expanding informal settlement in them. these settlements with differences in definition are known as occupational, changing, marginal, self-made and uncontrolled housing. it is estimated that about 1 billion man in all over the world live in such kinds of places. these zones are the texture for creation ...
