Personal floatation devices maintain either a semirecumbent flotation posture with the head and upper chest out of the water or a horizontal flotation posture with the dorsal head and whole body immersed. The contribution of dorsal head and upper chest immersion to core cooling in cold water was isolated when the confounding effect of shivering heat production was inhibited with meperidine (Dem...

ABSTRACTA novel floatation-spectrophotometric extraction method was developed for the recovery of tin (II) from aqueous samples prior to determination by UV spectrophotometric detection. The method is based on the formation of a complex between tin (II) and kalmagyte in pH=8. The complex is floated in the interface of n-hexane and aqueous phases. After removing the aqueous phase, the floated pa...

Solar energy is a sustainable clean energy. Evaporating seawater through solar thermal conversion an ideal solution to the global shortage of fresh water resources. At present, evaporating generally suffers from serious heat loss, salt accumulation and high cost. Here, non-woven technology spraying process, flexible fabric with rough, porous, fluffy surface prepared. Polyethylene terephthalate/...
