stress refers to the degree of force used in producing a syllable. all of the words in lexicon regardless of the apparent structure and the number of their syllables have their own stress. given that the regularities governing stress assignment in persian depend on the type of lexical category and that persian speakers have a tendency to assign stress at the end of words, the goal of the presen...

rails fracture by the growth of fatigue crack or critical crack is one of the prevalent defects in railway. the rail fracture, failure and stress analysis should be studied in order to prevention of rail fracture. in this paper, new formulation of contact stress for two rolling bodies is presented, where the results are closed to the hertz stress formulation. moreover, stress analysis is done b...

a method for error estimation of isogeometric analysis of plane stress problems which is the based on stress recovery and using the super convergent properties of the gauss points, has been already introduced. this paper is devoted to the development of the method and study of the effects of these supercovergent points on the solution improvement and error estimation of axisymmetric problems by...

introduction: stress is defined as any environmental change that disturbs the maintenance of brain homeostasis. stress leads to production of pro-inflammatory cytokines that provoke neurodegenerative disorders. in the present study, we investigated the effects of dalteparin on hippocampal neuronal death induced by chronic stress in rats. methods: the study was carried out on 60 adult male wista...

drought stress, especially drought at terminal stages, plays an important role in reduction of yield in field crops such as common beans. 50 genotypes of common bean including 3 control genotypes (dehghan, bahman and naz) were used to evaluate and identify the tolerant genotypes. this experiment were performed in a randomized complete block design (rcbd) with three replications under two condit...
