Flow regimes and liquid mixing in a draft tube gas-liquid-solid fluidized bed
(Pergamon-Elsevier Science Ltd, Oxford, 1992)
Flow behavior of gas bubbles, liquid and particles, and mixing in the liquid phase were studied in draft and annulus of a draft tube gas-liquid-solid fluidized bed. The experimental unit was a 80mm ID × 1.5 m column with ...
The thermal degradation kinetics of poly(chlorethylmethacrylates)
(John Wiley & Sons Ltd, W Sussex, 1992)
The thermal degradation kinetics of poly(2-mono-, 2,2-di- and 2,2,2-trichlorethyl methacrylate) and of the non-chlorinated poly(ethyl methacrylate) were studied by TG in the absence and presence of oxygen. The overall ...
The flow of the viscous fluid around the sphere in the range Re {similar or less-than} 2
(Springer Wien, Wien, 1992)
An improved and more correct solution of Oseen's equations, when the flow of the incompressible viscous fluid around the sphere is concerned, has been suggested. The new Oseen's correction term of the Stokes solution for ...
The corrosion behaviour of epoxy-resin electrocoated steel
(Pergamon-Elsevier Science Ltd, Oxford, 1992)
a.c. Impedance measurements carried out on epoxy-resin electrocoated steels have been used to determine the pore resistance of the organic films as a function of time of exposure to 3% NaCl solution. The time dependence ...
Synthesis and rheological study of some maleic acid and fumaric acid stereoregular polyesters - 8. Unsaturated polyester fibers
(Springer, New York, 1992)
First unsaturated polyester fibers were prepared starting from stereoregular, macromolecular poly(octamethylene fumarate). Fibers obtained from octamethylene copolyesters of fumaric and terephthalic acids manifested improved ...
Retention behavior of some amides in reversed- and normal-phase thin-layer chromatography
(Springer Heidelberg, Heidelberg, 1992)
The retention behavior and separation ability of reversed- and normal-phase TLC with, polar and nonpolar mobile phases, has been studied by measuring the retentions of a series of amides. The retention behavior and separation ...
Hydrogen peroxide oxidation on passive iron in alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 1992)
The kinetics of hydrogen peroxide oxidation were studied on passive iron in alkaline solutions of pH ranging from 9.8 to 13.8, using the rotating disk electrode. Measurements were taken using the linear sweep technique. ...
Reološka i druga svojstva N-metilmorfolin-N-oksidnog rastvora celuloze za vlakna / Rheological and other properties of cellulose solution in N-methylmorpholine-N-oxide
(Loznica : Viskoza, 1992)
Između različitih rastvarača za direktno rastvaranje celuloze i primene ovih rastvora za proizvodnju hemijskih celuloznih vIakana najperspektivniji je N-metilmorfolin-N-oksid (NMMO). Teižište ovog rada je na istraživanju ...
Kristalisanje koncentrovanih rastvora celuloze u N-metilmorfolin-N-oksidu / Crystallization of concentrated cellulose solutions in N-methylmorpholine-N-oxide
(Loznica : Viskoza, 1992)
U istraživanju mogućnosti dobijanja hemijskih celuloznih vlakana bez upotrebe ugljen disulfida posebna pažnja je posvećena takvim direktnim rastvaračima celuloze kao što su tercijerni amini. U ovom radu proučavane su pojave ...
Cathodic processes on corroding low-carbon steel: the effect of the degree of deformation
(Pergamon-Elsevier Science Ltd, Oxford, 1992)
The influence of the degree of deformation of low-carbon steel (0.48% Mn, 0.47% Si, 0.085% C) caused by mono-axial stretching was investigated with respect to the kinetics of electrochemical hydrogen evolution and the ...
