The short-term effects of high temperatures are a serious concern in the context of climate change. In areas that today have mild climates the research activity has been rather limited, despite the fact that differences in temperature susceptibility will play a fundamental role in understanding the exposure, acclimatization, adaptation and health risks of a changing climate. In addition, many s...
The temperature humidity index (THI) was originally developed for humans by Thom (1958) and extended to cattle by Berry et al (1964). It is currently used to estimate cooling requirements of dairy cattle in order to improve the efficiency of management strategies to alleviate heat stress. The Livestock Conservation Institute evaluated the biological responses to varying THI values and categoriz...
Dust is a phenomenon in arid and semi-arid areas due to high wind speeds on the un-polluted soil surface and prone to erosion. The occurrence of dust has always been a problem for residents in the western and southwestern regions of the country, has gradually spread to other provinces, including the capital. The study area is southwest of Iran, Khuzestan province. The latitude and longitude of ...
Background and aims: lack of thermal comfort in outdoor environments, can cause disorders and diseases, negative impact on productivity and performance, and even can cause death. Therefore, it is important to evaluate it. Various indices and models have been used to assess the level of comfort of humans. In most evaluations has been tried to estimate the comfort level using meteorological data ...
Abstrac t . The Fosberg fire weather index is a simple tool for evaluating the potential influence of weather on a wildland fire based on temperature, relative humidity and wind speed. A modification to this index that includes the impact of precipitation is proposed. The Keetch-Byram drought index is used to formulate a ‘fuel availability’ factor that modifies the response of the fire weather ...
The aim of the study was to evaluate the effect of storage and temperature on egg physical quality in Hyline chickens line. A total of 150 eggs from College of Natural Resources farm were sampled for the present experiment. About 70 eggs each were stored in home refrigerator (temperature, 7.46±0.23 ˚C; relative humidity, 24.80±0.05%) and room temperature (temperature, 22.98±1.12 ˚C; relative hu...
in order reaching to occurate water regime under minimum tillage system and its effect on the physiological indices of 3 rice cultivars an experiment was conducted as a split-plot design based on randomized complete block with three replication in the year of 2006-2007 at research field of shavour station. treatment contains three water regimes with one day or check, two (i2) and three days (...
Capabilities of an integrated ground-based system for the operational measurement of humidity profiles, using both an UHF wind profiler and a radiometer, are discussed. The combination takes advantage of the complementary characteristics of each instrument. The radiometer is able to give a fair evaluation of smoothed humidity and temperature profiles, while the wind profiler is more suited for ...
