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...

To explore the coupling effect of open space temperature and air velocity in hot-arid hot-humid climate regions rural China, 1690 valid data were obtained by long-term field tests questionnaires carried out regions. Results indicated that when operative is below 33.5 °C, mean thermal sensation decreases with increase region. When rose to greater than could be significantly reduced only over 1.0...

  Background Visceral leishmaniasis (VL) is most commonly found among children under the age of 10 in some provinces of Iran including Ardabil. As such, this study set out to determine the relationship between some climatic factors and the prevalence of VL in Northwest of Iran. Materials and Methods In this descriptive-analytic study, data collection was done on some climatic factors including ...

Despite provision of drinking water as the most common method of occupational heat stress prevention, there remains confusion in hydration messaging to workers. During work site interactions in a hot and humid climate, workers commonly report being informed to consume tepid fluids to accelerate rehydration. When questioned on the evidence supporting such advice, workers typically cite that flui...

The traditional architectural methods used in the historical cities of Iran provide useful information on various fields related to architecture and urban planning. Of particular interest are the techniques used for designing open and closed spaces in houses located in the hot and humid climate zone. The proportions observed for the courtyard in such houses have a great role in determining the ...

heat stress is a common occupational health hazard at outdoor workplaces especially in a hot-humid climate. overheating of the body can cause a number of problems, including heat rash, heat cramps, dizziness, heat exhaustion, and heat stroke. the present study aimed to assess heat stress indices including di, wbgt, and sw req /phs, as a mean to estimate the heat load on the employees of a petro...

Aflatoxins are potent mycotoxins that cause developmental and immune system suppression, cancer, and death. As a result of regulations intended to reduce human exposure, crop contamination with aflatoxins causes significant economic loss for producers, marketers, and processors of diverse susceptible crops. Aflatoxin contamination occurs when specific fungi in the genus Aspergillus infect crops...

Metabolic rate, a physiological trait closely related to fitness traits, is expected to evolve in response to two main environmental variables: (1) climate, low metabolic rates being found in dry and hot regions when comparing populations originating from different climates in a common garden experiment and (2) resource limitations, low metabolic rates being selected when resources are limited....
