Determination of metal content in some herbal drugs - Empirical and chemometric approach
(Elsevier, Amsterdam, 2005)
The concentrations of Cu, Zn, Mn, Fe, K, Ca, Mg, Al, Ba and B in 26 herbal drugs of special importance in phytopharmacywere studied. Flame atomic absorption and emission spectrometry (FAAS, FAES), as well as inductively ...
Solids residence time distribution in gas-flowing solids-fixed bed contactors
(Amer Chemical Soc, Washington, 2005)
Flowing solids residence time distribution in gas-flowing solids-fixed bed contactors was investigated using a tracer technique with a step signal as input. Particles of different color (all other properties being the same) ...
Artificial neural network modelling of uncertainty in gamma-ray spectrometry
(Elsevier, Amsterdam, 2005)
An artificial neural network (ANN) model for the prediction of measuring uncertainties in gamma-ray spectrometry was developed and optimized. A three-layer feed-forward ANN with back-propagation learning algorithm was used ...
Using the image analysis program for prediction of thermal stability behavior of refractory specimen
(8th International Symposium on Multifunctional and Functionally Graded Materials, FGM2004, 2005)
Most important properties which are usually measured for refractories are work temperature and thermal stability. Thermal stability of the alumina based samples was measured using a standard laboratory procedure, the water ...
Influence of heat treatment on mechanical and sorptional properties of viscose-based nonwovens
(Niscair, 2005)
The influence of heat treatment on sorptional and mechanical properties of viscose: polypropylene (90:10) blend nonwoven fleeces has been studied. It is observed that the heat treatment improves mechanical properties ...
Characterization of glycidyl methacrylate based copolymers by inverse gas chromatography under finite surface coverage
(Wiley-VCH Verlag Gmbh, Weinheim, 2005)
Inverse gas chromatography under finite surface coverage conditions (IGC-FC) was used for the investigation of sorption of hexane, benzene, chloroform and tetrahydrofuran on macroporous crosslinked poly[(glycidyl ...
Determination of thermodynamic properties of macroporous glycidyl methacrylate-based copolymers by inverse gas chromatography
(Wiley, Hoboken, 2005)
Macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) (PGME) was synthesized by suspension copolymerization and modified by ring-opening reaction of the pendant epoxy groups with ethylene ...
The influence of electrochemically deposited zinc alloys on steel on the protective properties of cathaporetic epoxy coatings / Uticaj elektrohemijski taloženih legura cinka na čeliku na zaštitna svojstva epoksidne kataforetske prevlake
(Engineering Society for Corrosion, Belgrade, Serbia, 2005)
Prior to cathaporetic epoxy coating deposition steel surface was modified by chemical deposition of hot dip galvanized steel and by electrochemical deposition of zinc alloys with iron group of elements (Ni, Co and Fe). The ...
Technological characterization of lactic acid bacteria isolated from Radan’s cheese / Karakterizacija tehnoloških osobina bakterija mlečne kiseline izolovanih iz sira sa planine Radan
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2005)
Isolation of lactic acid bacteria from artisanal dairy products is base for selection of new strains with properties which are important for their industrial application. In this work, characterization of 69 strains isolated ...
The influence of concentration of Nd-Fe-B powder in composite coating of optical fiber to the sensibility to external magnetic field
(University of Belgrade, Technical Faculty, Bor, 2005)
Multi-mode optical fiber with magnetic composite coating was investigated as an optical fiber sensor element (OFMSE) for magnetic field sensing The composite coating was formed with dispersions of permanent magnet powder ...
