Modelling of dissolved oxygen in the Danube River using artificial neural networks and Monte Carlo Simulation uncertainty analysis
(Elsevier Science Bv, Amsterdam, 2014)
This paper describes the training, validation, testing and uncertainty analysis of general regression neural network (GRNN) models for the forecasting of dissolved oxygen (DO) in the Danube River. The main objectives of ...
Unsupervised classification and multi-criteria decision analysis as chemometric tools for the assessment of sediment quality: A case study of the Danube and Sava River
(Elsevier, Amsterdam, 2016)
The aim of this study was to evaluate the quality of freshwater sediments by means of three chemometric techniques for multi-criteria analysis and decision: self-organizing network (SON), self-organizing map (SOM) and ...
The effect of T4 heat treatment on the microstructure and corrosion behaviour of Zn27Al1.5Cu0.02Mg alloy
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The effect of heat treatment on the microstructure and corrosion behaviour of Zn27Al1 5CuO 02Mg alloy was examined The alloy was prepared by melting and casting route and then thermally processed (T4 regime) Corrosion ...
Adsorption of arsenate on iron(III) oxide coated ethylenediamine functionalized multiwall carbon nanotubes
(Elsevier Science Sa, Lausanne, 2012)
New criteria in assessing the quality of drinking water reduced the maximum permissible concentration of arsenic from 50 mu g L-1 to 10 mu g L-1 and set a requirement for the development of new technologies for arsenic ...
Polyurethane networks based on polycaprolactone and hyperbranched polyester: Structural, thermal and mechanical investigation
(Elsevier Science Sa, Lausanne, 2019)
A series of environmentally friendly polyurethane (PU) networks based on polycaprolactone as soft segment (SS) and Boltorn (R) aliphatic hyperbranched polyester of the second pseudo generation as crosslinking agent was ...
Structural, ferroelectric and magnetic properties of BiFeO3 synthesized by sonochemically assisted hydrothermal and hydro-evaporation chemical methods
(Elsevier Sci Ltd, Oxford, 2016)
BiFeO3 powders were synthesized by sonochemically assisted hydrothermal and hydro-evaporation methods. The X-ray diffraction confirmed the presence of secondary phases, Bi25FeO39 and Bi2Fe4O9, in as prepared BiFeO3 powders. ...
Synthesis of medium-chain length capsinoids from coconut oil catalyzed by Candida rugosa lipases
(Elsevier Sci Ltd, Oxford, 2017)
A commercial preparation of Candida rugosa lipases (CRL) was tested for the production of capsinoids by esterification of vanillyl alcohol (VA) with free fatty acids (FA) and coconut oil (CO) as acyl donors. Screening of ...
Mechanochemically assisted solid-state and citric acid complex syntheses of Cu-doped sodium cobaltite ceramicsh
(Elsevier Science Sa, Lausanne, 2015)
In the last decade, the sodium cobaltite ceramic became a promising candidate for potential thermoelectric applications, because of its large thermopower and low resistivity. In this work, polycrystalline samples of ...
