Nitrate removal from water by biological denitrification / Uklanjanje nitrata iz vode za piće primenom biološke denitrifikacije
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2012)
Ground water pollution by nitrate from routine agricultural practices is a common and growing problem in the major agricultural areas of the world. The concentration of nitrates in these areas may exceed the maximal limited ...
Corrosion of cannon 75/27, model 1911. déport, from the collection of the Military Museum in Belgrade / Korozija topa 75/27, model 1911. deport iz kolekcije Vojnog muzeja u Beogradu
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2012)
This paper analyzes the state of the French Cannon 75/27 model 1911. Déport made of steel. The amount of non-corroded materials, the presence of cracks and other defects in the cannon were determined by the radiographic ...
Numerical simulation of 3D flow at 90o straight-channel confluence with bed elevation discordance
(TuTech Verlag, TuTech Innovation GmbH, 2012)
The paper aims at studying the effect of difference in bed elevations between the tributary and main canals (∆zT) on the flow in the confluence hydrodynamics zone. To do this, a 3D numerical model is used for flow simulation ...
Enhanced Arsenic Removal from Water by Activated Red Mud Based on Hydrated Iron(III) and Titan(IV) Oxides
(Chemical Engineering Communications, 2012)
In this study, acid heat-activated neutralized red mud (AB) was promoted as an efficient sorbent for the removal of inorganic arsenic from water. Three sorbents: neutralized red mud (Bauxsol), acid-treated Bauxsol (aBauxsol), ...
Review: The approaches for estimation of limit of detection for ICP-MS trace analysis of arsenic
(Elsevier B.V., 2012)
The analytical properties of an analytical method must be evaluated through validation protocols. Beside specificity and/or selectivity, linearity of calibration, repeatability and accuracy, the most important parameters ...
Environmental impact assessment of construction of the Ada bridge / Analiza nekih uticaja na životnu sredinu izgradnje mosta na Adi
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2012)
Construction of the new cable stayed bridge on the Sava River in Belgrade - the 'Ada Bridge', required extensive foundation works at the entrance of the Ada Bay, with two environmentally unfavourable consequences -increased ...
Hydraulic design of morning glory spillway with a deflector upstream of the vertical bend / Određivanje dimenzija šahtnog preliva empirijskim jednačinama
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2012)
Hydraulic design of shaft spillways (morning-glory spillways) with flow deflector before the vertical bend is considered. Based on the physical hydraulic model investigations of several structures and available experience ...
Controls at river confluences with discordant beds / Uticajni činioci na rečnim ušćima sa izdignutim dnom pritoke
(Savez građevinskih inženjera Srbije, Beograd, 2012)
The role of four parameters that are controlling river confluence hydrodynamics at discordant beds confluences is investigated using 3D numerical model. These are: the junction angle α, the momentum-flux ratio between the ...
Different approach for calculation of inflow on storm water sewer pumping station: Case study KCS Nova 1 on New Belgrade / Mogućnosti za proračun protoka na kišnoj kanalizacionoj crpnoj stanici - primer KCS Nova 1, Novi Beograd
(Savez inženjera i tehničara Srbije, Beograd, 2012)
In the process of making mathematical models, a common problem is lack or missing data that could be used for calibration and verification of the model. In that case, we have to somehow use available data to calculate the ...
Concave Antiprisms of Second Sort with Regular Polygonal Bases
(Novi Sad: Faculty of Technical Sciences, University of Novi SadNovi Sad: Serbian Society for Geometry and Graphics (SUGIG), 2012)
The paper discusses determining the positions and spatial coordinates of the vertices of polyhedral structures - concave antiprisms of second sort. These polyhedra originate from folding the double row strip of equilateral ...
