A marathon is a grueling endurance race, and runners are at risk of heatstroke. Therefore, the thermal environment course should be accurately assessed. Solar radiation, factor in environment, particularly affected by surrounding environment. In this study, we proposed method to calculate wet-bulb globe temperature (WBGT) short period time using geographic information system (GIS) data, conside...

Introduction: In this study we (i) introduced time-motion analysis for assessing the impact of workplace heat on the work shift time spent doing labor (WTL) of grape-picking workers, (ii) examined whether seasonal environmental differences can influence their WTL, and (iii) investigated whether their WTL can be assessed by monitoring productivity or the vineyard manager's estimate of WTL. Metho...

Military activities in hot environments pose 2 competing demands: the requirement to perform realistic training to develop operational capability with the necessity to protect armed forces personnel against heat-related illness. To ascertain whether work duration limits for protection against heat-related illness restrict military activities, this study examined the heat strain and risks of hea...

Several optimal discharge pressure correlations for transcritical CO2 heat pump in literature have been discussed in this paper. Most of them are related to the ambient temperature, the evaporation temperature and the gas cooler outlet temperature. A revised optimal discharge pressure model as the function of ambient temperature and water outlet temperature is developed based on earlier experim...

Abstract Agricultural irrigation has significantly reshaped the land surface energy and water balance. Previous studies have well investigated its cooling effect on air temperature ( T ). However, increasing humidity which can intensify humid heat was often overlooked, particularly over urban areas with high population density, , consequently greater exposure to moist stress. In this study, usi...

Introduction: Global warming is likely to affect certain groups such as workers in heat-producing industries. With limited research exploring an important area, this study aimed explore the heat stress vulnerability and adaptive strategies of indoor small-scale factory workers. Methods: This was a cross-sectional mixed-method approach used. The setting units. quantitative component included env...
