Different approaches to two-dimensional numerical modelling of natural watercourses
(Union of Croatian Civil Engineers and Technicians, 2017)
Results obtained by analysis of three different approaches to numerical modelling of open watercourses are presented in the paper. Two examples of flow, uniform flow on the physical model of a curve at the Tisza River and ...
Investigation of accessory elements of representative petrologic radioactivity carriers at Stara Planina, Serbia
(Nuclear Technology and Radiation Protection, 2019)
The present study deals with the abundance of the most common accessory elements of radioactivity carriers on the Stara Planina mountain at four defined locations. All investigated locations have increased radioactivity, ...
Photodegradation of dimethenamid-p in deionised and ground water
(Savez hemijskih inženjera, Beograd, 2016)
The study of photodegradation of dimethenamid-P herbicide was performed in deionised and ground water using TiO2 as a catalyst under UV light. The effect of electron acceptor (H2O2), scavenger of (OH)-O-center dot radicals ...
Corrosion of an austenite and ferrite stainless steel weld / Korozija zavarenog spoja austenitnog i feritnog nerđajućeg čelika
(Srpsko hemijsko društvo, Beograd, 2011)
Dissimilar metal connections are prone to frequent failures. These failures are attributed to the difference in the mechanical properties across the weld, the coefficients of thermal expansion of the two types of steels ...
Analytical methods for arsenic speciation analysis / Analitičke metode za analizu arsenovih jedinjenja
(Srpsko hemijsko društvo, Beograd, 2013)
Arsenic exists in the form of various chemical species differing in their physicochemical behaviour, toxicity, bioavailability and biotransformation. The determination of arsenic species is an important issue for environmental, ...
The sorption of inorganic arsenic on modified sepiolite: the effect of hydrated iron(III) oxide
(Srpsko hemijsko društvo, Beograd, 2014)
The sorption of inorganic arsenic species, As(III) and As(V), from water by sepiolite modified with hydrated iron(III) oxide was investigated at 25 degrees C through batch studies. The influence of the initial pH value, ...
The effects of oscillating nozzle on Christiansen's uniformity coefficient
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2015)
Rainfall simulators have been used in research for more than 40 years. Unfortunately, there is not much literature on their construction and calibration. This paper presents a rainfall simulator experimental rig, developed ...
Challenging analytical task: analysis and monitoring of arsenic species in water
(Environmental Engineering and Management Journal, 2014)
Analysis and monitoring of arsenic is still a challenging analytical task. Due to its complex behaviour (different forms of arsenic that can be present depending on pH and oxidation states of arsenic) as well as demanding ...
Corroded scale analysis from water distribution pipes / Analiza korozionih ljuski u vodovodskim cevima
(Savez hemijskih inženjera, Beograd, 2011)
The subject of this study were the steel pipes that are part of Belgrade's drinking water supply network. In order to investigate the mutual effects of corrosion and water quality, the corrosion scales on the pipes were ...
Application of artificial neural networks for hydrological modelling in karst
(Union of Croatian Civil Engineers and Technicians, 2018)
The possibility of short-term water flow forecasting in a karst region is presented in this paper. Four state-of-the-art machine learning algorithms are used for the one day ahead forecasting: multi-layer perceptron neural ...
