Effects of waste sulfur content on properties of self-compacting concrete
(Consejo Superior Investigaciones Cientificas-Csic, Madrid, 2020)
Self-compacting concrete (SCC) contains fine mineral fillers such as limestone powder. The idea of this study was to partially replace limestone with waste sulfur since it is hydrophobic, insoluble in water and therefore ...
The advantage of ultrasound during electrodeposition on morphology and corrosion stability of Zn-Co alloy coatings
(Taylor & Francis Ltd, Abingdon, 2020)
The influence of ultrasound agitation on the properties of electrodeposited Zn-Co coatings was analysed and compared with coatings deposited by using magnetic stirring. The morphology and chemical composition of the deposits ...
Procedure of solidification and stabilization of heavy metals from mine waste waters adsorbed on fly ash pellets into enviromentally acceptable building material / Postupak solidifkacije i stabilizacije teških metala iz otpadnih rudničkih voda adsorbovanih na peletama u ekološki prihvatljiv građevinski materijal pepela
(Zavod za intelektualnu svojinu Republike Srbije, 2020)
Stabilization of heavy metals, especially copper, from acidic mine wastewater is performed by their solidification into sulfur polymer concrete as an environmentally acceptable building material. The procedure is carried ...
A Three-electrode gas arrester for low voltage isolation coordination
(Elsevier Sci Ltd, Oxford, 2020)
This work aims is to design, fabricate and test a gas surge arrester with optimum characteristics based on testing the influence of all parameters that affect the characteristics of gas surge arresters for the coordination ...
The effect of temperature on pollen germination and pollen tube growth of quince cultivars
(IV Balkan Symposium on Fruit Growing, 2020)
The effect of three different temperatures (8, 16 and 24 degrees C) on pollen germination and pollen tube growth in vitro in eight quince cultivars ('Leskovacka', Vranjska', 'Morava', 'Pazardzijska', 'Hemus', 'Asenica', ...
Utilization of gamma and e-beam irradiation in the treatment of waste sludge from a drinking water treatment plant
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
An increasing production of drinking water and a significant amount of waste in the form of treated sludge can lead to a serious environmental problem. The high organic content in the sludge, together with the high summer ...
Thermo-responsive hydrogels based on poly(N-isopropyl- acrylamide) and hyaluronic acid cross-linked with nanoclays
(Srpsko hemijsko društvo, Beograd, 2020)
Semi-interpenetrating polymer networks (SIPN) based on thermo-responsive poly(N-isopropylacrylamide) (PNIPA) and water-soluble sodium salts of linear hyaluronic acid (Na-HA) were physically cross-linked with synthetic ...
Amides as a model system of low molar mass algal organic matter. Influence on the adsorption of p-nitrophenol on activated carbon
(Elsevier, Amsterdam, 2020)
In this study, the adsorption equilibrium and diffusivity parameters of p-nitrophenol were estimated for water containing different concentrations of secondary amides. Commercial powdered activated carbon was used as an ...
Sensitivity analysis of the variational model for the particulate expansion of fluidized beds
(Taylor & Francis Inc, Philadelphia, 2020)
Fluidization experiments were performed by using spherical and non-spherical particles to examine the sensitivity of the variational model to three input parameters: U-mf, epsilon(mf) and U-t. Several correlations for U-mf, ...
A detailed experimental and computational study of monocarbohydrazones
(Elsevier, Amsterdam, 2020)
The substituent and solvent effect on intramolecular charge transfer (ICT) of twelve monocarbohydrazones (mCHs) were studied using experimental and theoretical methodology. The effects of specific and non-specific ...
