Segregation in water fluidized beds of sand particles
(Elsevier, 2013)
Fluidization experiments were conducted on four fractions of filtration (quartz) sand using columns of 144 and 64mm i.d. The size distribution of the fractions obtained by sieving followed an approximately modified normal ...
Effect of welded joint imperfection on the integrity of pipe elbows subjected to internal pressure
(University of Osijek, Tech Fac, Slavonski Brod, 2013)
Since local defects reduce the load-carrying capacity and deformation ability of a piping system, an analysis is undertaken to quantify the influence of weld defects on integrity of the pipe elbows subjected to internal ...
Development starter cultures for production functional beverages from cow's whey
(UNIVERSITY OF BELGRADE - TECHNICAL FACULTY IN BOR, 2013)
Organoleptic characteristics of fermented dairy beverages largely depend on the proper selection of bacteria used for the construction of starter cultures and purpose of this study was to evaluate activity of eight ...
Screening for factors affecting dextransucrase production from Leuconostoc mesenteroides isolated from water kefir grains using statistical approach
(Serbian Chemical Society, 2013)
A leuconostoc strain was isolated from water kefir grains obtained from a household in Belgrade, Serbia. Strain was identified as Leuconostoc mesenteroides after biochemical and 16S rRNA sequencing studies. The isolated ...
Immobilized cells
(John Wiley & Sons, 2013)
Modification of chitosan by zeolite A and adsorption of Bezactive Orange 16 from aqueous solution
(Composites: Part B: Engineering, 2013)
This study represents new material based on chitosan modified by zeolite A as adsorbent for anionic dye, using Bezactive Orange 16 as a model compound. Interactions between dye and chitosan/zeolite A film at initial ...
Tailoring the supercapacitive performances of noble metal oxides, porous carbons and their composites / Rasvetljavanje superkondenzatorskih odlika oksida plemenitih metala, poroznih ugljeničnih materijala i njihovih kompozita
(Serbian Chemical Society, 2013)
Porous electrochemical supercapacitive materials, as an important type of new-generation energy storage devices, require detailed analysis and knowledge of their capacitive performances under different charging/discharging ...
Analysis and comparison of mass transfer phenomena related to Cu2+ sorption by hydroxyapatite and zeolite
(Elsevier B.V., 2013)
Zeolite and hydroxyapatite (HAP) are well-known sorbent materials, with high capacities for removal of toxic heavy metals. In this study, the influence of process parameters onto kinetics of Cu2+ sorption by zeolite and ...
Arsenic Removal from Water Using Industrial By-Products
(Hindawi Limited, 2013)
In this study, removal of arsenic ions using two industrial by-products as adsorbents is represented. Removal of As(III) and As(V) from water was carried out with industrial by-products: residual from the groundwater ...
The Galvanostatic Reduction on Modified Platinum Electrode and Determination of Trinitrotoluene in Neutral Solution
(Esg, Belgrade, 2013)
The study of the electrochemical reduction on acetonitrile modified platinum electrode and determination of trinitrotoluene (TNT) in neutral solution by simple galvanostatic technique is presented here. The obtained ...
