BACKGROUND Heat stress as a physical harmful agent can increase the risk of health and safety problems in different workplaces such as mining. Although there are different indices to assess the heat stress imposed on workers, choosing the best index for a specific workplace is so important. Since various criteria affect an index applicability, extracting the most effective ones and determining ...

Drought is a wide-spread problem seriously influencing durum wheat (Triticum durum Desf.) production and quality, but development of resistant cultivars is hampered by the lack of effective selection criteria. The objective of this study was to evaluate the ability of several selection indices to identify drought resistance cultivars under a variety of environmental conditions. Twenty four duru...

this paper presents a case study to determine the efficiency of the currently used heat stress indices in correlation with wet bulb globe temperature (wbgt) as a permissible index at a foundry plant and to evaluate the extent of the physiological responses such as heart rate and body temperature in correlation with heat stress indices. the field consisted of a foundry plant where a shift work w...

in order to evaluate of drought tolerance in different canola varieties based on stress evaluation indices in terminal growth duration, an experiment was conducted as split-plot design on randomized complete block design with four replications at experimental field of seed and plant improvement institute, karaj in 2005 and 2006. results using stress susceptibility index (ssi) and tolerance inde...

in order to study drought tolerance indices and to introduce tolerant maize hybrids in drought conditions, an experiment was conducted at the experimental field of seed and plant improvement institute, in 2009. the experiment was carried out using split-plot in a randomized complete block design (crbd) with three replications. the main plots consisted of three levels of irrigation regimes (irri...

abstract water deficit is a major problem for the successful production of agricultural products in iran. this research was conducted to evaluate drought tolerance indices and identifying drought tolerant cultivars of canola. twenty eight canola cultivars were sassed implementing complete block designs experiments in normal and drought stress conditions at isfahan university of technology resea...

in order to study stress tolerance indices and identifying tolerance genotypes to drought stress condition 16 genotypes of durum wheat were assessed in a randomized complete block design with four replications under two irrigated and rainfed conditions in the research station located in west of iran ilam in 2006- 2007. results showed that variation in among durum wheat genotypes under irrigated...
