Respirator performance rating tables have been constructed for hot, humid (29 degrees C, 95% RH); hot, dry (49 degrees C, 30% RH); and cold, dry (-32 degrees C, 70% RH) conditions. These tables convey expected wearer performance percentages compared to unmasked workers for various mask elements and work rates. The hot, humid condition was found to be the most severe overall. Many table entries ...

Hot and humid environments are prevalent in many industries. People working in hot and humid environments are at great risk of specific heat-related disorders, the productivity decrease and safety problems. In order to guarantee workers’ health and safety, safety evaluation and early warning rating of the hot and humid environments are studied in this paper. The fuzzy analytic hierarchy process...

Temperature variability impact on physiological, hematological and biochemical parameters of growing and adult Karan Fries cattle was studied during hot humid, winter, spring and summer. During forenoon and afternoon the respiration rate (RR) and rectal temperature (RT) increased by 4.67 and 3.67 breaths/min and 0.87°C and 0.77°C respectively in growing KF cows during summer over spring. The re...

this paper discusses the results of the full-scale field measurement study to investigate the most efficient application strategy of the hybrid turbine ventilator (htv) in improving the indoor thermal comfort in hot-humid tropics. the effects of three different htv application strategies performance on improving the levels of indoor air temperature, relative humidity (rh) and air velocity were ...

Even though studies investigating the effect of road transportation on haematological parameters in goats from temperate and hot tropical environments are numerous, few studies have focused on the recovery rate following transportation, especially in the hot, humid tropical environment. This study investigated the haematological parameters and oxidative stress response of goats subjected to 7 h...

Introduction Anhidrosis is a decreased ability to sweat in response to increased body temperature. It most often occurs in horses living in hot, humid climates like Florida and other Gulf coast states. It is an important problem for performance horses because thermoregulation is mainly accomplished by sweating in the horse. Between 65-70% of heat is lost via the evaporation of sweat and the hum...

conclusions the mean heart rate was higher in participants who were overweight than those with normal weight. results the mean and standard deviation of the heart rate in the hot climatic condition and moderate exercise were 103.84 (3.34) for normal weight subjects and 108.67 (3.27) for overweight subjects. the mean and standard deviation of the heart rate in a very hot climatic condition and l...

The objective of this study was to examine interactions between climatic factors, parity, and weaning-to-first-mating interval (WMI) for total number of pigs born at subsequent parity (TPB) of female pigs serviced during 2 seasons. The present study analyzed records of 27,739 gilts and 127,670 parity records of sows in 95 Japanese herds; the records included females that were serviced between J...

The purpose of this observational study was to determine the circulating leukocyte subset response to completing the 2013 Hotter'N Hell Hundred recreational 164-km road cycle event in a hot and humid environmental condition. Twenty-eight men and four women were included in this study. Whole blood samples were obtained 1-2 hours before (PRE) and immediately after (POST) the event. Electronic siz...
