The gas holdup in a multiphase reciprocating plate column filled with carboxymethylcellulose solutions / Утицај концентрације раствора и степена полимеризације карбоксиметилцелулозе на садржај гаса у реактору са вибрационом мешалицом
(Serbian Chemical Society, 2005)
Gas holdup was investigated in a gas-liquid and gas-liquid-solid reciprocating plate column (RPC) under various operation conditions. Aqueous carboxymethylcellulose (sodium salt, CMC) solutions were used as the liquid ...
The surface energy of disperse cadmium electrodeposits formations / Површинска енергија електрохемијског формирања дисперзног талога кадмијума
(Serbian Chemical Society, 2005)
The surface energy of disperse cadmium electrodeposits formation was determined by using a procedure described earlier.1,2 It was shown that the surface energy strongly depends on the composition of the solution from which ...
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 ...
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), ...
Comparative analysis of laboratory accreditation in Bulgaria, Lithuania, Slovakia and Serbia and Montenegro
(Springer-Verlag, 2005)
The development of an internationally recognized laboratory accreditation process, accompanied by a mutual recognition agreement (MRA), is an issue of great interest in Central and Eastern European countries. This paper ...
Antifreeze life cycle assessment: II. Mathematical modelling / Životni ciklus antifriza: II. Rezultati matematičkog modelovanja
(Association of Chemical Engineers of Serbia, 2005)
A mathematical model based on the mass and energy balances of all the processes included in antifreeze life cycle assesment (LCA) was defined in the first part of this study [1]. The part of energy that can be transformed ...
Lactic acid fermentation in vegetable juices supplemented with different content of brewer’s yeast autolysate / Mlečno-kisela fermentacija sokova povrća obogaćenih različitim sadržajem autolizata pivskog kvasca
(Faculty of Technology, Novi Sad, 2005)
The work is concerned with the conditions for lactic acid fermentation in a mixture of beetroot (Beta vulgaris L) juice and carrot (Daucus carota L) juice and different content of brewer’s yeast autolysate with Lactobacillus ...
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 ...
