A pseudo-fluid representation of vertical liquid-coarse solids flow / Vertikalno kretanje tečnosti i čvrstih čestica tretirano kao pseudo-fluid
(Serbian Chemical Society, 2005)
The pseudo–fluid concept has been applied for the prediction of the pressure gradient and voidage in vertical liquid-coarse solids flow. Treating the flowing mixture as a single homogenous fluid, the correlation for the ...
Solvent and structural effects on the kinetics of the reactions of cycloalkenylcarboxylic and cycloalkenylacetic acids with diazodiphenylmethane
(Wiley, Hoboken, 2005)
The rate constants for the reaction of different cycloalkenylcarboxylic, cycloalkenylacetic acids, and phenylacetic acid with diazodiphenylmethane were determined in 12 aprotic solvents at 30 degrees C. in order to explain ...
Bioethanol from corn meal hydrolyzates / Proizvodnja bioetanola na hidrolizovanom kukuruznom brašnu
(Association of the Chemical Engineers of Serbia, 2005)
The two-step enzymatic hydrolysis of corn meal by commercially available α-amylase and amyloglycosidase and the subsequent or simultaneous ethanol fermentation of the hydrolyzates by Saccharomyces cerevisiae yeast were ...
An algorithm for LC1 optimization
(Faculty of Organizational Sciences, Belgrade, 2005)
In this paper an algorithm for LC1 unconstrained optimization problems, which uses the second order Dini upper directional derivative is considered. The purpose of the paper is to establish general algorithm hypotheses ...
Comparison of Hydroxyapatite Sorption Properties Towards Cadmium, Lead, Zinc and Strontium Ions
(Trans Tech Publications, 2005)
Apatites are well known matrix for heavy metal immobilization and remediation of
ground water and contaminated soils. In this work, capacities of different synthetic hydroxyapatite
(HAP) samples for Pb, Cd, Sr and Zn ...
The Modeling of Insulin Controlled Release Process From Fibrous Artificial Store
(Emerald Group Publishing Ltd., 2005)
In the past, insulin was frequently administered by hypodermic injection, as liquids forms. To avoid problems incurred through the utilization of the injectable route of insulin administration, new dosage forms containing ...
Structural and crystallization characteristics of K 2 O· TiO 2 ·3GeO 2 glass / Strukturní a krystalizaèní charakteristiky k2o·tio2·3geo2 skel
(Institute of Chemical Technology, 2005)
Structure and crystallization of K 2 O·TiO 2 ·3GeO 2 glass have been investigated by means of Fourier transform infrared spectroscopy (FTIR), differential thermal analysis (DTA), differential scanning calorimetry (DSC), ...
Kinetic study of formic acid oxidation on carbon-supported platinum electrocatalyst
(Elsevier Science Sa, Lausanne, 2005)
Oxidation of formic acid on the platinum catalyst supported on high area carbon was investigated by potent iodynamic and quasi-steady-state polarization measurements. It was found that the poisoning of the reaction occurred ...
Heat of vaporization from the corresponding states principle / Određivanje toplote isparavanja na bazi principa korespondentnih stanja
(Association of the Chemical Engineers of Serbia, 2005)
The heat of vaporization was estimated from the corresponding states principle. The reported values of the functions δS(0) and δS(1), or their analytical expressions, are presented. Tabulated values of δS(0) and δS(1) were ...
Kinetics and mechanism of As2S2 oxidation / Кинетика и механизам процеса оскидације једињења Аs2S2
(Serbian Chemical Society, 2005)
The kinetics of realgar (As2S2) oxidation was studied under isothermal and non-isothermal conditions. The obtained values of the activation energy indicate that the process occurs in the kinetic domain with the realgar ...
