conditional monitoring is prerequisite to prevent severe damage or falling down the trees. problems such as trunk decays, reduces trees resistance against wind and floods. in this study, a mathematical modeling technique is being selected to determine the trees strength against such events. finally, an applicable model for safety factor was created by having numeral (dimensions of crown and tru...

The aim of this study was to analyze the cultural adaptation of the European Spanish version of the Perceived Stress Scale (PSS; Cohen, Kamarak, & Mermelstein, 1983), for its use in Mexican samples. Using a random sample of students, internal consistency was analyzed and the factor structure of the Spanish version of the PSS was compared with the factor structure found in the English version. I...

The internal (or residual) stress is among the key notions to describe the state of the systems far from equilibrium. Such stress is invisible on the macroscopic scale where the system is regarded as a black-box. Yet nonequilibrium macroscopic operations allow to create and observe the internal stress. We present in this lecture some examples of the internal stress and its operations. We descri...

the speed of the development and changes of technology is so fast and astonishing that causes the increase of stress and diminishing societies health. there are some factors involved in the creation of the stress. those factors included as the stresses caused by external factors of the organization internal factors of the organization, collective and individual stresses. the relationship betwee...

The present study examines stress among parents of children with intellectual disability. 102 parents formed the sample of this study, 30 of whom had children without disability. A stress assessment test with internal validity of 0.608 was utilised. This test has two parts: physical and mental, former with 19 items and latter with 21 items. T test was applied to check differences in stress, gen...

The filling of thin-walled steel tubes with quartz sand can help to prevent the premature buckling of the steel tube at a low cost. During an impact, the internal stress of the quartz sand-filled steel tube column is subjected to not only axial force but also lateral confining force, resulting in complicated internal stress. A suitable sensor for monitoring the internal stress of such a structu...
