Release and diffusion studies of hydrogels based on itaconic acid
(8th Conference of the Yugoslav Materials Research Society, 2007)
Controlled release studies of drugs (theophylline (TH), fenethylline hydrochloride (FE) and gentamicin sulphate (GS)) from pH sensitive poly(2-hydroxyethyl methacrylate/itaconic acid) (P(HEMA/IA)) hydrogels obtained by ...
Ca-alginate hydrogel mechanical transformations - The influence on yeast cell growth dynamics
(Elsevier, Amsterdam, 2007)
A mathematical model was formulated to describe yeast cell growth within the Ca-alginate microbead during air-lift bioreactor cultivation. Model development was based on experimentally obtained data for the intra-bead cell ...

(Elsevier Sci Ltd, Oxford, 2007)
Polyimide resins were obtained from the reaction between N-[4-benzoyl-2-(2,5-dioxo-2,5-dihydro-pyrrol-1-yl)-phenyl]-acetamide and the following compounds with terminal amino groups: urea, 4-[(4-aminophenyl)sulfonyl] aniline, ...
Modeling and investigation of SiGe based MOSFET structure transport characteristics
(8th Conference of the Yugoslav Materials Research Society, 2007)
The focus of this paper was the investigation and modeling of transport characteristics in a strained SiGe based MOSFET structure, which might be of fundamental importance for the understanding of its operating characteristics. ...
Densities and excess molar volumes of the binary 1-propanol plus chloroform and 1-propanol plus benzene and ternary 1-propanol plus chloroform plus benzene mixtures at (288.15, 293.15, 298.15, 303.15, 308.15, and 313.15) K
(Amer Chemical Soc, Washington, 2007)
Densities p and excess molar volumes V-E of the binary 1-propanol + chloroform and 1-propanol + benzene and ternary 1-propanol + chloroform + benzene mixtures have been determined. Experimental p measurements have been ...
An experimental study of the partial oxidation of ethane to ethylene in a shallow fluidized bed reactor / Eksperimentalno ispitivanje parcijalne oksidacije etana do etilena u reaktoru sa plitkim fludizovanim slojem
(Serbian Chemical Society, Belgrade, 2007)
The partial catalytic oxidation of ethane to ethylene was investigated experimentally in a shallow fluidized bed. The performances of two catalyst types, pure γ-Al2O3 and V2O5/γ-Al2O3 particles 1.8 mm in diameter, were ...
Classification of soil samples according to geographic origin using gamma-ray spectrometry and pattern recognition methods
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Multivariate data analysis methods were used to recognize and classify soils of unknown geographic origin. A total of 103 soil samples were differentiated into classes, according to regions in Serbia and Montenegro from ...

A series of microcrystalline products containing the gamma-Bi2O3 phase doped with Co, Fe, Mn, Pb, Sb, Si, Ti, V and Zn has been prepared by solid state reaction. Based on the heating temperature and heating time, the ...
Alginate microbeads as a cell support for cartilage tissue engineering: Bioreactor studies
(8th Conference of the Yugoslav Materials Research Society, 2007)
Alginate was shown to be a suitable support for entrapment and cultivation of chondrocytes and bone marrow stromal cells, which under appropriate in vitro conditions synthesized cartilaginous components. The main limitation ...
Nonlinear frequency response method for estimation of single solute adsorption isotherms. Part I. Theoretical basis and simulations
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
A method for determination of single solute adsorption isotherms based on the analysis of the nonlinear frequency response (FR) of a chromatographic column is developed theoretically. In order to demonstrate this method, ...
