Abstract A wet-bulb temperature of 35 ○ C is widely used as the threshold for human survivability, but not a particularly accurate metric heat stress. For person in shade, more index, which based on model thermoregulation that accounts metabolic heat, radiation, respiratory ventilation, and finite wind speeds. The index has two critical values: highest healthy core can be maintained survivable....

Day and night comfort votes were recorded from Caucasian residents at Weipa, a mission station in the hot humid tropics of North Queensland, Australia. The limit of day comfort for more than 50% of the men was 81 5°F. (27-5°C.) "normal" corrected effective temperature; the night limit was 78'00F. (25 5°C.). Day comfort limits correlated well with air conditions at which sweat was apparent: nigh...

In pressure-atomized sprays, the liquid droplets and gas in two-phase flow field may exhibit self-similar properties, so that spray as a whole be described self-similar. This description is used to model mass transfer from ambient by evaporation of droplet liquid. The concentration vapor phase solution related transport equation form. transform source representing effect compared against profil...

background: a cross sectional study was conducted to determine the association between occupational stress risk factors and salivary alpha-amylase activity levels among fresh fruit bunch (ffb) cutters at oil palm plantation.  methods: a total of 109 ffb cutters were selected from two oil palm plantations in pulau carey, selangor at west coast of malaysia in 2015. questionnaires were used to det...

Statistical post-processing is an indispensable tool for providing accurate weather forecasts and early warnings extremes. Most statistical univariate, with dependencies introduced via use of empirical copula. Standard methods take a dependence template from either the raw ensemble output (ensemble copula coupling, ECC) or observations (Schaake Shuffle, SSh). There are drawbacks to both methods...

The aims of the present field-based study were to investigate changes in fit horses undergoing acclimatisation to a hot humid environment and to provide data on which to base recommendations for safe transport and acclimatisation. Six horses (age 7-12 years) were flown from Europe to Atlanta and underwent a 16 day period of acclimatisation. Exercise conditions during acclimatisation (wet bulb g...

This study assesses heatstroke risk in the near future (2031–2050) under RCP8.5 scenario. The developed model is based on a generalized linear with number of ambulance transport due to (hereafter patients heatstroke) as explained variable and daily maximum temperature or wet bulb globe (WBGT) explanatory variable. With temperature, we performed projection case considering only climate change (C...

The thermal strain imposed on helicopter aircrew by chemical protective (NBC) clothing in summer in Germany has been assessed in a laboratory simulation. The environmental conditions used were dry bulb temperature 35 degrees C, wet bulb temperature 19 degrees C and a wind speed of 2.0 m X s-1. The NBC equipment imposed a significant thermal strain on the crewman when compared with standard summ...
