Ozone absorption in raw waters
(Serbian Chemical Society, 2008)
The ozone absorption in raw water entering the main ozonization step at the Belgrade drinking water supply plant was investigated in a continuous stirred tank reactor (CSTR). A slow chemical reaction rate of dissolved ozone ...
Low-temperature tension properties of glass-epoxy composite materials / Određivanje zateznih svojstava staklo-epoksi kompozitnih materijala na niskim temperaturama
(Faculty of Technology, Novi Sad, 2005)
The aim of this paper was to present the determination of tensile strength Rm and modulus of elasticity Et of glass-epoxy composites at two different temperatures (at room temperature t=20°C, and at t =-50°C). Standard ...
Comparative examination of activity of different strains of lactic acid bacteria in beetroot and carrot juice / Uporedna ispitivanja aktivnosti sojeva bakterija mlečno-kiselinskog vrenja u soku cvekle i mrkve
(Faculty of Technology, Novi Sad, 2000)
Fermented vegetable juices are an important component of nutrition, because the fermentation improves the quality of natural vegetable juices by its products, which are important biotic substances. Beetroot (Beta vulgaris ...
The effect of TiO 2 on the structure and devitrification behavior of potassium titanium germanate glass
(Springer Netherlands, 2006)
The effect of replacing 20 mol% of GeO 2 by TiO 2 on the properties of potassium germanate glass was investigated. The structure and devitrification behaviour of glasses were studied by Fourier transform infrared spectroscopy ...
Karakteristike kvašenja pletenina na bazi konoplje namenjenih za medicinske svrhe / Liquid wetting properties of hemp based knitted fabrics for hospital uses
(Savez inženjera i tehničara tekstilaca Srbije, 2006)
U okviru ovog rada pletenine na bazi konoplje podvrgnute su ispitivanju maksimalnog kapaciteta apsorpcije tečnosti kao i brzine njene apsorpcije. S obzirom da su za izradu pletenina upotrebljene nehomogene kompleksne pređe ...
Kinetics of the hydrogen evolution reaction on Fe-Mo film deposited on mild steel support in alkaline solution
(Pergamon-Elsevier Science Ltd, Oxford, 2005)
The mechanism and kinetics of the hydrogen evolution reaction were studied. in 1.0 mol dm(-3) NaOH solution on Fe-Mo alloy electrodes prepared by electrodeposition at constant current densities from a pyrophosphate bath. ...
The effect of reversing current deposition on the apparent density of electrolytic copper powder / Uticaj reversne struje na nasipnu masu pri elektrolitičkom taloženju bakarnog praha
(Serbian Chemical Society, 2002)
The possibility of depositing copper powders with different apparent density by changing the shape of reversing current wave is shown. The morphology and crystallinity of powder particles can be varied considerably by ...
Removal of methyl tertiary butyl ether from wastewaters using photolytic, photocatalytic and microbiological degradation processes
(Elsevier Science Bv, Amsterdam, 2007)
Contamination of groundwater by methyl tertiary butyl ether (MTBE), that is detected in wastewater of petrochemical industry, is an increasing problem to water supply companies. The subjects of this research were the methods ...
Prediction of ductile fracture initiation using micromechanical analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
In the paper ductile fracture initiation analysis of low-alloyed ferritic steel has been made by application of two micromechanical models: the Rice-Tracey void growth model and the Gurson-Tvergaard-Needleman (GTN) model. ...
