BACKGROUND Global climate change is already increasing the average temperature and direct heat exposure in many places around the world. OBJECTIVES To assess the potential impact on occupational health and work capacity for people exposed at work to increasing heat due to climate change. DESIGN A brief review of basic thermal physiology mechanisms, occupational heat exposure guidelines and ...

The purpose of this study is to provide industry practitioners with a better understanding of the impacts of high-temperature conditions on construction labor productivity. Such information could assist in the establishment of plans to prevent heat-stress injuries and help improve the safety and comfort of construction labor working environments. On-site WBGT (Wet Bulb Globe Temperature) data a...

The efficacy of ingestion of ice slurry on actual outdoor endurance performance is unknown. This study aimed to investigate ice slurry ingestion as a cooling intervention before a 10 km outdoor running time-trial. Twelve participants ingested 8 g · kg (- 1) of either ice slurry ( - 1.4°C; ICE) or ambient temperature drink (30.9°C; CON) and performed a 15-min warm-up prior to a 10 km outdoor run...

In this study, the equations obtained non-iteratively are presented for moist air thermodynamic properties as a function of dry-bulb temperature and relative humidity. In this regard, an artificial neural network (ANN) was performed by using MATLAB software. In the ANN, dry-bulb temperature and relative humidity were specified as inputs, and water vapor saturation and partial pressures, wet-bul...

BACKGROUND Workers laboring in steel industries in tropical settings with high ambient temperatures are subjected to thermally stressful environments that can create well-known risks of heat-related illnesses and limit workers' productivity. METHODS A cross-sectional study undertaken in a steel industry in a city nicknamed "Steel City" in Southern India assessed thermal stress by wet bulb glo...

analyses and thermal infrared channels 4 and 5 noaa- avhrr images. this research was carried out in lut desert located in center of sub-tropical divergence dominant in' iranian plateau. the physical and thermal properties of the various desert surfaces have been determined using correlation relationships between the desert variables including: dark sand, normal sand, marl, saline soil, soil dep...

This paper aims to assess the effects of urbanization on heat stress comparing two neighbourhoods in tropical city Rio de Janeiro, Brazil, that differ terms building density and vegetation cover. The outdoor was evaluated by Wet Bulb-Globe Temperature (WBGT) Index, which considers combined effect air temperature, relative humidity, solar radiation wind speed, during year 2016. urban neighbourho...

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...
