Leaching kinetics of lead from lead (II) sulphate in aqueous calcium chloride and magnesium chloride solutions
(Elsevier Science Bv, Amsterdam, 1997)
The kinetics of lead leaching from lead (II) sulphate in aqueous calcium chloride and magnesium chloride solutions was studied. The leaching rates of lead were measured by using an agitated vessel at atmospheric pressure, ...
Thermal shock of ceramic material : Comparison of resistance parameter with the critical ΔT values ΔTc = ΔTc(Bi) of ceramic materials
(Trans Tech Publications Ltd., 1997)
Thermal shock resistance of ceramic material can be characterized by using resistance parameters or critical temperature difference. Correlation between fracture resistance parameter, R and critical temperature difference, ...
Selection of Calculation Method for Temperature Distribution in 99 Mass-% Al 2 O 3 Refractories
(Verlag Schmidt GmbH, 1998)
Refractories are constantly exposed to temperature changes. In most cases this exposure causes damage. In this work, attention is paid to problems of non-steady-state heat transfer. Some analytical and numerical methods ...
Electrical resistance of cotton-metal fibre yarns
(Inst Chemical Fibres, Lodz, 1999)
Yarns representing cotton-metal fibre blends were studied. The electrical resistance of yarns including different fractions of cotton and metal fibres was compared with cotton yarns having the same nominal characteristics. ...
Liposomes as carriers of antimicrobial drugs
(Taylor & Francis Ltd, Abingdon, 1997)
Liposome are promising drug carrier systems being developed. Their successful use in the treatment of several diseases demonstrates that a solid rationale for clinical development of liposomes as antimicrobial drug carriers ...
Rhizopus arrhizus lipase-catalyzed interesterification of palm oil midfraction in a gas-lift reactor
(Elsevier Science Inc, New York, 1994)
Celite-immobilized lipase from Rhizopus arrhizus was encapsulated in lecithin reverse micelles and used to interesterify triacylglycerols of palm oil midfraction with stearic acid in n-hexane. The reaction kinetics were ...
One more general method for solving Oseen's equations
(Springer Wien, Wien, 1991)
In this paper we have proposed a new method for solving the Oseen's equations. It has been testified in the case of the normal flow around the cylinder for the Re number being much smaller than 1. The step forward was to ...
The applicability of DTG to polymerisation studies
(John Wiley & Sons Ltd, W Sussex, 1993)
The application of derivativ thermogravimetry (DTG) to investigate polymerisation mechanisms is illustrated using the radical polymerisation of di-n-alkyl itaconates as well as the photoinitiated polymerisation of methyl ...
The electro-oxidation of glycerol on the gold(100)-oriented single-crystal surface and poly crystalline surface in 0.1 M NaOH
(Elsevier Science Sa, Lausanne, 1991)
Formation mechanism, morphology and synthesis of alpha-Al2O3, mullite and cordierite particles obtained by the ultrasonic spray pyrolysis
(Trans Tech Publications Ltd, Durnten-Zurich, 1996)
The present stage in our investigations of the synthesis of high-purity, submicrometer and spherical Al2O3, mullite and cordierte powders obtained by the ultrasonic spray pyrolysis is presented. The influence of precursors ...
