Mesozoic carbonate rocks in Serbia used as dimension stone
Vesna Matović, Tijana Vojnović Ćalić (2016)The building industry in Serbia uses, to a great extent, imported natural stone for architectural purposes. The significance of local deposits, particularly limestones, is not adequately perceived despite the country’s abundance of these valuable resources. Therefore, this study focuses on Serbia’s Mesozoic carbonate rocks, specifically on the deposits of four selected quarries: Klisura, Skrzut, Struganik, and Tisnica. The quality and prospects of the application of these limestones has not yet been the subject of a detailed, comprehensive investigation. Therefore, ...... (Fig. 1d). The exploitation takes place at a few exploitation levels on both sides of the riverbed covering an area of approximately 0.12 km? (Živković and Paunović 2000). Materials and methods Carbonate rocks collected from four different locations in Serbia (quarries: Klisura, Skrzut, Struganik ...

Hybrid Model for Optimisation of Waste Dump Design and Site Selection in Open Pit Mining
Aleksandar Doderovic, Svetozar-Milan Doderovic, Sasa Stepanovic, Mirjana Bankovic, Dejan Stevanovic (2023)Waste management is an unavoidable technological operation in the process of raw material extraction. The main characteristic of this technological operation is the handling of large quantities of waste material, which can amount to several hundred million cubic metres. At the same time, this operation must comply with all administrative and environmental standards. Therefore, optimising waste rock management (particularly haulage and dumping) has the potential to significantly improve the overall value of the project. This paper presents a hybrid ...Aleksandar Doderovic, Svetozar-Milan Doderovic, Sasa Stepanovic, Mirjana Bankovic, Dejan Stevanovic.

Kroskorelacione analize nivoa podzemnih voda i nivoa Velike Morave, vodomerni profil Ljubičevski Most
Sliv Velike Morave predstavlja glavni drenažni rečni sistem Republike Srbije (RS) iz razloga što zahvata oko 42 % njene površine. Zbog visokog kvaliteta zemljišta Pomoravlja, kao i značajnih rezervi podzemnih voda, ono predstavlja najgušće naseljenu oblast u užoj Srbiji. Od privrednih grana najzastupljenija je poljoprivredna proizvodnja. Bilo je istorijskih pokušaja da ova reka postane i plovna ali do sada bezuspešno. Zbog svoje značajnosti za RS, na ovoj reci je još pre više od 100 godina uspostavljen monitoring nivoa voda ...režim površinskih i podzemnih voda, kroskorelaciona analiza, brzina kretanja podzemnih voda, reka Velika MoravaMilan Kresojević, Vesna Ristić Vakanjac, Dušan Polomčić, Boris Vakanjac, Jugoslav Nikolić.

Ground surface subsidence monitoring using sentinel-1 in the “Kostolac” open pit coal mine
Zoran Gojković, Milan Kilibarda, Ljiljana Brajović, Miloš Marjanović, Aleksandar Milutinović, Aleksandar Ganić (2023)Open pit coal mining affects surrounding populated areas, resulting in terrain surface deformation. Surface deformation should be monitored as often as possible to control deformations and prevent potential incidents. This paper analyzes time series deformation estimated from the Sentinel-1 satellite images using the Persistent Scatterer Interferometry method to monitor subsidence rates caused by open pit mining activities. It is possible to measure deformations using classical geodetic methods, but those are rarely used in practice because they are time-consuming and ...Zoran Gojković, Milan Kilibarda, Ljiljana Brajović, Miloš Marjanović, Aleksandar Milutinović, Aleksandar Ganić.

DFT study of free radical scavenging activity of erodiol
Zoran Marković, Jelena Đorović, Milan Dekić, Milanka Radulović, Svetlana Marković, Marija Ilić (2013)Antioxidant activity of erodiol was examined at the M05-2X/6-311+G(d,p) level of theory in the gas and aqueous phases. The structure and energy of radicals and anions of the most stable erodiol rotamer were analyzed. To estimate antioxidant potential of erodiol, different molecular properties were examined: bond dissociation enthalpy, proton affinity together with electron transfer energy, and ionization potential followed by proton dissociation enthalpy. It was found that hydrogen atom transfer is the prevailing mechanism of erodiol behavior in gas; ...Zoran Marković, Jelena Đorović, Milan Dekić, Milanka Radulović, Svetlana Marković, Marija Ilić.
