Standard No. EN 15831:2004 provides 2 methods of calculating insulation: parallel and serial. The parallel method is similar to the global one defined in Standard No. ISO 9920:2007. Standards No. EN 342:2004, EN 14058:2004 and EN 13537:2002 refer to the methods defined in Standard No. EN ISO 15831:2004 for testing cold protective clothing or equipment. However, it is necessary to consider sever...

The in vitro antimicrobial activity of Sapindus mukorossi and Emblica officinalis fruit extracts were studied against Streptococcus mutans, Staphylococcus aureus, Lactobacillus acidophilus, Candida albicans and Saccharomyces cerevisiae. The acetone, ethanol, methanol, hot water and cold water extracts of S.mukorossi exhibited antimicrobial activity against one of the tested microorganisms i.e. ...

Site U1328 (Scientific Prospectus Site CAS-06A) is located within a seafloor cold-vent field, with dimensions 2 km by 4 km, consisting of at least four vents associated with nearsurface faults. The cold vents are characterized by near-vertical seismic blank (or wipe-out) zones that are between 80 and several 100 m wide, and show a clear E-W trend as identified from 3D seismic imaging. The most ...

Artificial freshwater recharge is commonly used to mitigate seawater intrusion and restore salinized aquifers in coastal zones. While the temperature of recharged often differs from that aquifers, effects differences on water flow salinity distributions are rarely examined. Based laboratory experiments numerical simulations, we found response distribution cold prolonged. Cold performs better co...

BACKGROUND Little evidence is available about the association between temperature and cerebrovascular mortality in China. This study aims to examine the effects of ambient temperature on cerebrovascular mortality in different climatic zones in China. METHOD We obtained daily data on weather conditions, air pollution and cerebrovascular deaths from five cities (Beijing, Tianjin, Shanghai, Wuha...

Heptahelical protein 1 (HHP1) is a negative regulator in abscisic acid (ABA) and osmotic signalling in Arabidopsis. The physiological role of HHP1 was further investigated in this study using transgenic and knock-out plants. In HHP1::GUS transgenic mutants, GUS activity was found to be mainly expressed in the roots, vasculature, stomata, hydathodes, adhesion zones, and connection sites between ...

Climate change affects building cooling demand; however, little has been done to explore this effect and show its variability in different climatic zones. This review organizes summarizes studies which have simulated the impact of climate on requirements, critically analyzes effectiveness mitigation strategies proposed by these alleviate impact. The methodology selected that reported demand dis...

A risk assessment of vegetation zone responses to climate change was conducted using the classical Holdridge life zone model on the Loess Plateau of Northwest China. The results show that there are currently ten vegetation zones occurring on the Loess Plateau (1950–2000), including alvar desert, alpine wet tundra, alpine rain tundra, boreal moist forest, boreal wet forest, cool temperate desert...

It is commonly thought hot diapiric flows prevail in the mantle wedge above the subducting slab. However, hydration and partial melting along the slab can create a situation in which a Rayleigh-Taylor instability can develop at the top of a cold subducting slab. We have modelled numerically with a high-resolution 2-D regional model this parodoxically interesting geological phenomenon in which r...
