Threshold limit values (TLVs) are intended to protect workers from the severest effects of thermal stress and to establish the exposures to heat in working conditions. Earlier, acute heat strokes often occurred as a result of working in hot environments in Japan. However, acute heat strokes recently sometimes occurred in outdoor work environments such as industrial constructions and agriculture...

[1] Trends and variations of Goddard Satellite-based Surface Turbulent Fluxes (GSSTF) version 2c (GSSTF2c) latent heat flux (LHF) are examined. This version of LHF takes account of the correction in Earth incidence angle. The trend of global mean LHF for GSSTF2c is much reduced relative to GSSTF version 2b Set 1 and Set 2 for the same period 1988–2008. Temporal increase of GSSTF2c LHF in the tw...

Weather, climate and tourism are interconnected in many different ways. All of them are of both global and local significance. Weather and/or climate information is of interest for tourists and the tourist industry especially before and during the vacation period. Relevant climate information can be obtained through different media (tourist guide books, Internet, CD, DVD) or through weather ser...

In the present study, comprehensive stress testing of Dexketoprofen trometamol was carried out according to ICH guideline Q1A (R2). Dexketoprofen trometamol is subjected to stress conditions of hydrolysis, oxidation, photolysis and neutral decomposition. Additionally, the solid drug is subjected to 50 °C for 60 days in dry-bath, and to the combined effect of temperature and humidity, with and w...

Background: The poultry industry suffers losses from problems as pale, soft and exudative (PSE), and dark, firm and dry (DFD) meat can develop in meat as a result of shortand long-term stress, respectively. These abnormalities are impacted by pre-slaughter animal welfare. Methods: This work evaluated the effects of open vehicle container microclimate, throughout the 38 ± 10 km journey from the ...

Temperature-humidity index (THI) values applicable to South Africa and Namibia have been established during this investigation for each month of the year by means of computerized modelling and mapping techniques. The data indicate that each year heat stress risk areas (HSRA's) expand from August to January and retract from February to July. The THI values classified according to the Livestock W...

Heat stress may contribute to decreased match performance when football is played in extreme heat. This study evaluated activity patterns and thermal responses of players during soccer matches played in different environmental conditions. Non-acclimatized soccer players (n=11, 20±2 years) played two matches in conditions of moderate heat (MH) and high heat (HH) index. Core temperature (T(c) ) a...

A specific, accurate, precise and sensitive validated reversed phase liquid chromatographic method has been developed for the determination of valacyclovir in the presence of its degradation products in bulk drug as well as tablet dosage form. As per ICH guideline Q1A (R2), drug was subjected to all stress conditions such as hydrolysis (acidic, neutral and alkaline), oxidation (3 % H2O2 v/v), p...

The recent large scale deployment of multi crystalline silicon photovoltaic (PV) modules in the field has risen the need for indepth studies of degradation in a fast and efficient manner. In this context, different standard test procedures as specified under IEC 61215 viz. thermal cycling (TC), humidity freeze (HF) and damp heat (DH) have been developed for crystalline silicon PV modules [1]. T...

Background: Climate change is one of the most complex human challenges in future. One consequences climate exposure people to heat stress, especially outdoor environments. The aim this study was model changes trend stress environments coming decades context and global warming. Methods: Wet Bulb Globe Temperature (WBGT) index, Canadian Earth System Model (CanESM2), Statistical Down Scaling (SDSM...
