results high-ranking officials in our study had less work experience in their current jobs and smoked fewer pack-years of cigarette, but they had higher waist and hip circumference, higher triglyceride level, more stress from role overload and responsibility, and higher total stress score. our group of office workers had more occupational stress because of role ambiguity and insufficiency, but ...

In the present research, the mixed-mode fracture mechanics analysis in a plate with central hole under tensile loading is considered. It is assumed that a plate containing two symmetrical hole-edge cracks is bonded with two dissimilar planes. The stress intensity factors at the crack tips are calculated. The problem is modeled in Casca software and this model is analyzed with Franc software. Th...

eight genotypes of spring safflower (carthamus tinctorius l.) were evaluated for several physiological traits under stress and non-stress water regimes. data were analyzed using principal factor analysis. the factor analysis technique extracted six factors under non-stress conditions. six factors explained about 80% of the total variation, and only 40% of the variance was accounted for by the f...

Stress is a health epidemic of the 21st Century. It can affect anyone at any time, altering or impairing their general (WHO). The study utilized quantitative-descriptive correlational research design to determine stress factors among two hundred randomly selected nursing students University Bohol, aided by self-made questionnaire adopted from Student Nurse Index (SNSI) Jones and Johnston 1999. ...

This study aimed to identify the level of stress in teenagers from multicultural families Korea and examine factors influencing this stress. cross-sectional utilized 15th (2019) Youth Risk Bsehavior Web-based Survey. Of 57,303 survey participants, 749 reported that their father, mother, or both parents were born outside Korea. These individuals selected as participants. We examined general char...

in this paper, the interface crack of two non-homogenous functionally graded materials is studied. subsequently, with employing the displacement method for fracture of mixed-mode stress intensity factors, the continuous variation of material properties are calculated. in this investigation, the displacements are derived with employing of the functional graded material programming and analysis o...

rice plants are injured at the seedling stage in early spring in northern iran. in order to study rice response to cold stress, the expression of osdreb1a, osap37, osmyb3r-2, and osnac6 genes encoding transcription factors was observed in 14-day-old seedlings of cold-tolerant genotype pr and cold-sensitive cv. hashemi during cold stress (5°c for 24 h) using the differential display method and t...

background: nursing is naturally a stressful job. stress in nurses can cause depression, isolation from patients, absence and decrease in their qualification. this study aimed to determine the causes of job stress in nurses of kashan, iran. materials and methods: in this cross-sectional study, 189 nurses from kashan hospitals of different wards were studied. the information collection tool was ...
