This study investigated cold weather safety footwear and the possible thermal effects of steel toe caps in footwear. Two boot models were manufactured and used in two variants - with (As and Ws) and without (An and Wn) steel toe cap. The boot insulation was measured with an artificial, heated foot (AHF). Experiments with 6 male subjects with boots Ws and Wn consisted of sitting for 60 minutes at -

Popular Abstract in Swedish Oberoende av om det är i ett samhälle, datornätverk eller organen i en mänsklig kropp, så är behovet av kommunikation stort i en komplex miljö. Eftersom den komplicerade människokroppen är beroende av kommunikation för att reglera funktioner, skickas otaliga mängder signaler oavbrutet. För att signalerna skall vara meningsfulla så måste de kunna tas emot och behandlas. Intercellular communication is of crucial importance in regulating physiology and G-protein coupled receptors (GPCRs) have evolved as an important mechanism in this process. Of the approximately 800 human GPCRs, about 160 are still considered to be “orphan” receptors for which an endogenous ligand remains to be identified. Since an estimated 50% of all clinical drugs act on 30 known GPCRs, the rem

Gold-bearing pyrite ores are refractory and must be pre-treated to break down the sulphides by oxidation. This is done usually by roasting, bacterial oxidation and smelting. Moreover, ores with high sulphur content require pre-treatment to prevent excessive chlorine consumption, an important source of pollution. The pyrite waste created in mining operation presents serious problems on the environm

Vocal tract area functions estimated from 38 sets of X-rayed vowel articulations collected from the literature and from new X-ray motion films of English and Arabic speech reveal four constriction locations: along the hard palate, along the soft palate, in the upper pharynx and in the lower larynx. Each location is appropriate for a definable class of vowel qualities, confirming the quantal nature

Kapitlet diskuterar temat det goda livet och upplevelsesamhället utifrån den tyske sociologen Gerhard Schulzes författarskap. Som sådant utgör det ett bidrag till en samtidsanalys.

The former Soviet empire spanned eleven time zones and contained half the world's forests; vast deposits of oil, gas and coal; various ores; major rivers such as the Volga, Don and Angara; and extensive biodiversity. These resources and animals, as well as the people who lived in the former Soviet Union – Slavs, Armenians, Georgians, Azeris, Kazakhs and Tajiks, indigenous Nenets and Chukchi – were
