the thermally stimulated discharge (tsdc) current is studied for acrylonitrile butadiene rubber (nbr) loaded with different high abrasion furnace carbon black (haf). tsdc peak appears only for higher haf contents > 60phr (70 and 80phr of haf contents), the tsdc spectra consist of a sharp peak corresponding to a peak temperature tm which is slightly shifted to higher temperature for 70phr ...
The induction characteristic of halothane in nitrous oxide and oxygen were compared with halothane in oxygen alone and intravenous induction with thiopentum and succinylcholine.Materials and Methods: A vital capacity technique was used for the gaseous induction groups using a mapleson F system and a 1-litre reservoir bag. four end points of anesthesia were recorded: time to cessation of hand gr...
whereas in electrical discharge machining (edm) the heat flux entering the workpiece is extremely high, the fourier heat conduction model may fails. this article reports on determination of temperature distribution in the workpiece due to edm using non-fourier heat conduction model. equations are solved by deriving the numerical solution. the temperature layers and profiles of sample calculatio...
abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
