The first standards for chemical protective clothing (CPC) emerged mid to late 1980's and have evolved since as most standards are revisited every 5 yr. Over the past years, we have also seen a strengthening of the chemical and worker protection legislation around the globe (various forms of REACH) but also protection of workers. The most prevalent standards originate under the auspices of the ...

for the first time in the history of logic, abd al razzaq al-jili (d. 570/1174), in the treatise al-lame fi al-shakl al-rabe, dealt with the modal syllogisms of the fourth figure. previous to him, dinha, the priest, and ibn salah al-hamadani had discussed the non-modal moods of the fourth figure. jili’s treatise deals only with simple modalities and ignores the complex ones. his pupil, fakhr al...

This paper presents a brief review on the current status of biodiesel production and its performance and emission characteristics as compression ignition engine fuel. This study is based on the reports on biodiesel fuel published in the current literature by different researchers. Biodiesel can be produced from crude vegetable oil, non-edible oil, waste frying oil, animal tallow and also from a...

Helictites--an enigmatic type of mineral structure occurring in some caves--differ from classical speleothems as they develop with orientations that defy gravity. While theories for helictite formation have been forwarded, their genesis remains equivocal. Here, we show that a remarkable suite of helictites occurring in Asperge Cave (France) are formed by biologically-mediated processes, rather ...

occupational health and safety systems have a unique role in sustainable development of hazardous industries. the aim of this research is investigating and assessing of h3se performance excellence systems. to achieve mentioned goal by qualitative approach and multi grounded theory tools h3se excellence model was described. mentioned tools contain two qualitative research methods (meta synthesis...

Biodiesel produced from non-edible plant sources is cost-effective, biodegradable, environment friendly, and compatible with petro-diesel, but new extraction processes still need to be discovered. Here, we explored the fuel properties of seeds six sources, including Sapindus mukorossi (Soapnut, SP), Vernicia fordii (Tung, TO), Ricinus communis (Castor, CA), Toona sinensis (Juss. TS), Ailanthus ...
