The WBGT heat stress index has been well tested under a variety of climatic conditions and quantitative links have been established between WBGT and the work-rest cycles needed to prevent heat stress effects at the workplace. While there are more specific methods based on individual physiological measurements to determine heat strain in an individual worker, the WBGT index is used in internatio...
Introduction: Many studies, especially in recent years, have evaluated and controlled the occupational heat stress in Iran using environmental indices. However, so far, no comprehensive study has been conducted to review and classify these studies. Therefore, this study aimed to review and investigate the occupational studies performed by environmental heat stress indices in Iran. Material and...
Background and Objective: Inappropriate atmospheric conditions are harmful factors that cause particular problems in certain seasons (summer or winter). The occupation of confectionery in the regions like Ilam causes severe problems due to the heat generated by the nature of the work (synthetic heat-generating processes) and the heat resulting from the climatic conditions in the region. Exposur...
Development of a personal heat strain risk assessment (PHSRA) index in workplaces and its validation
sericulture has played a very important role in the socio-economic empowerment of rural and semi-urban population. the eco-friendly nature of the industry, in addition to its employment generation potential, low investments and frequent returns, has rendered the industry as one of the most suitable land based economic activity, particularly in the context of global movement against environmenta...
conclusions the was could be used for reliable assessment of work ability among iranian workers. to improve the worker’s work ability, interventional programs should focus on the alteration and correction of work schedule, and increasing the supervisor’s support for the young workers. objectives the present study aimed to assess work ability using wai and was instruments and to compare their re...
background cerebral state index (csi) is derived from electroencephalograms to monitor the level of consciousness during anesthesia. some evidence shows that this indicator has been used to detect cerebral ischemia and prognostic outcomes for traumatic brain injury (tbi). objectives the present study was designed to investigate the correlation between glasgow coma score (gcs) and csi for brain-...
Objective(s): Several beneficial effects have been attributed to the probiotic lactic acid bacteria. It was determined that lactobacilli can exert antiproliferative effects on the various cancer cell lines including colon cancer. Effects of lactic acid bacteria on colon cancer may vary from strain to strain and there is a need to find the new probiotic strains with tumor suppressing properties ...
This research presents temperature distribution and thermal strain of functionally graded material cylinders with varying thickness and temperature-dependency properties that are subjected to heat fluxes in their inner and outer layers. The heterogeneous distribution of properties is modeled as a power function. Using first-order temperature theory and the energy method, governing equations are...
Type II diabetes mellitus is associated with congestive heart failure with preserved ejection fraction. This group of patients has been assumed to have isolated diastolic dysfunction; however, the longitudinal systolic contraction of the left ventricle has not been studied previously. The objective of the present study was to investigate the longitudinal contraction of the left ventricle in nor...
