Synthesis of new hyperbranched urethane-acrylates and their evaluation in UV-curable coatings
(Elsevier Science Sa, Lausanne, 2004)
Three series of hyperbranched urethane-acrylates (HB-UA), based on aliphatic hyperbranched polyesters and polyethyleneglycol acrylate, were prepared and evaluated for use in UV-curable coatings. UV-curing kinetics were ...
Optimization of artificial neural network for retention modeling in high-performance liquid chromatography
(Elsevier, Amsterdam, 2004)
An artificial neural network (ANN) model for the prediction of retention times in high-performance liquid chromatography (HPLC) was developed and optimized. A three-layer feed-forward ANN has been used to model retention ...
Protective properties of epoxy coatings electrodeposited on steel electrochemically modified by Zn-Fe alloys / Zaštitna svojstva epoksidnih kataforetskih prevlaka na čeliku elektrohemijski modifikovanom Zn-Fe legurama
(Association of Chemical Engineers of Serbia, 2004)
Epoxy coatings were electrodeposited on steel and steel modified by Zn-Fe alloys using the constant voltage method. Zn-Fe alloys were electrodeposited on steel at different current densities. The effect of the Zn-Fe alloy ...
Kinetics of the reaction of 5-substituted orotic acids with diazodiphenylmethane / Kinetika reakcije 5-supstituisanih orotinskih kiselina sa dizaodifenilmetanom
(Serbian Chemical Society, Belgrade, 2004)
Rate konstants for the reaction of eight 5-substituted orotic acids with diazodiphenylmethane (DDM) in dimethylformamide (DMF) were determined at 30 ºC by the known spectrophotometricmethod. The determined rate constants ...
Control of microbial growth in industrial water cooling and air conditioning systems / Kontrola mikrobnog rasta u industrijskim rashladnim sistemima i sistemima za kondicioniranje vazduha
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2004)
Biological impurity in water cooling systems is a result of growth of various microorganisms (viruses, bacteria, fungi and algae). The influence of microbial processes in water cooling systems can be recognized from two ...
Polyacrylamide and poly(itaconic acid) complexes
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
Intermolecular complex formation through hydrogen bonding between poly(itaconic acid), partially neutralized and non-neutralized, and polyacrylamide was studied by potentiometry. The complexes were obtained by template ...
Obtaining crystals in a laboratory furnace
(Elsevier, Amsterdam, 2004)
A model of an air cooler (telescopic cold bridge) with a column of Tamman test tubes (telescopic test comb), installed in a laboratory tube furnace, for regulation and simultaneous crystallization tests at different ...
Efficiency of membrane extraction of phenol-4-aminoantipyrine complex with n-alcohols
(Elsevier, Amsterdam, 2004)
In this study, the membrane extraction of phenol-4-aminoantipyrine complex with the series of aliphatic alcohols was investigated by monitoring the efficiency of the process. A commercial polysulphone hollow-fiber membrane ...
Applicability of cubic equation of state mixing rules on correlation of excess molar volume of non-electrolyte binary mixtures
(Taylor & Francis Ltd, Abingdon, 2004)
The excess molar volume V data of the binary liquid systems were correlated by the Peng-Robinson-Stryjek-Vera equation of state coupled with two different types of mixing rules: composition dependent van der Waals mixing ...
Characterization and antimicrobial activity of bacteriocin 217 produced by natural isolate Lactobacillus paracasei subsp paracasei BGBUK2-16
(Int Assoc Food Protection, Des Moines, 2004)
The strain Lactobacillus paracasei subsp. paracasei BGBUK2-16, which was isolated from traditionally homemade white-pickled cheese, produces bacteriocin 217 (Bac217; similar to7 kDa). The onset of Bac217 biosynthesis was ...
