Optimization of chromatographic separation of solvent mixture based on thermodynamic functions of adsorption and dissolution
Basad on determined specific retention volumes for components of solvent mixture, their heats of adsorp­ tion (-AH) on a chromosorb W AW DMCS (80-100)mesh su­ pport and heats of dissolution (-AH) onExpand
Difference equations and local convergence of inexact Newton methods
Abstract In this paper, some observations on local convergence of inexact Newton methods are given. The basic perturbation result concerning difference equations due to Perron and Ostrowski is usedExpand
[Determination of solvent vapors in the air during use of Butapren OBT III glue].
Gas chromatographic method was applied to determine the mixture of extraction benzine, benzene, toluene and ethyl acetate vapours. These are the components of several types of butapren glues. OptimumExpand
