Overview of the hydrogeological investigations of recently discovered world class deposits in Serbia
Europe industry has growing concerns on availability of the raw materials. To address this challenge, the European Commission has created a list of critical raw materials for the EU, launched EIT Raw Materials initiative, and continuously support research projects (like INTRAW, UNEXMIN etc.) with the aim of reducing the dependency and meeting growing demands. In the last 15 years Serbia is experiencing new bust in geological exploration of mineral deposits. Currently 167 exploration licenses are active, covering approximately 6000 ...Nebojša Atanacković, Vladimir Živanović, Veselin Dragišić, Sava Magazinović.

The impact of temporal variability of groundwater levels on groundwater vulnerability maps in karst terrains – a case example of the Perućac spring catchment area
Groundwater vulnerability maps represent an essential tool for protecting karst groundwater resources. Vulnerability assessment is usually based on spatial evaluation of various parameters that affect the vulnerability degree and regulate the protection role of the unsaturated zone. Most of these parameters, like soil and geology conditions, are constant and do not change during the year or over several years. In contrast, some parameters, such as the groundwater level, depend on the variability of recharge conditions. By considering the variability ...Vladimir Živanović, Igor Jemcov, Nebojša Atanacković.

Hydrochemical indicators of groundwater flow in the area of “Čukaru Peki” Cu-Au underground mine in eastern Serbia
The physical and chemical properties of groundwater, together with the groundwater levels regime and rock hydraulic properties, are often used to understand and conceptualize the hydrogeological system. Prediction of the influence of mining works on groundwater, and vice versa, is a challenge due to significantly altered groundwater flow patterns in the raw materials exploitation areas in relation to natural conditions. Therefore, multiple parameters are assessed and monitored before and during exploitation to properly characterize and quantify the system for ...Nebojša Atanacković, Vladimir Živanović, Jana Štrbački, Veselin Dragišić, Ivana Cvejić.

Fizičko-hemijsko raspadanje krečnjaka ugrađenih u objekte Beogradske tvrđave i mogućnost konsolidacije
Maja Z. Franković (2022)Beogradska tvrđava, spomenik kulture od izuzetnog značaja za Republiku Srbiju, izgrađena je od krečnjaka badenske starosti. Njihova litološka heterogenost, u sadejstvu sa uticajima okruženja, rezultira visokim intenzitetima raspadanja. Korelacijom intrinzičnih sa ekstrinzičnim faktorima, definisani su fizičko-hemijski procesi raspadanja ugrađenih mikrofacija krečnjaka. Aplikacijom neorganskih konsolidanata na karbonatnoj bazi (nano-kreča i Ca-acetoacetata) i alkoksisilana, te korelacijom fizičko-mehaničkih svojstava pre i nakon tretmana, ispitana je efektivnost u pogledu zaustavljanja dekohezije krečnjaka.

The use of biological markers in determination of origin and type of organic matter in the Tisza river sediments
Snežana Štrbac, Gordana Gajica, Aleksandra Šajnović, Nebojša Vasić, Ksenija Stojanović, Branimir Jovančićević (2013)The objective of the study was to determine the origin and type of organic matter (OM) of the Tisza recent sediments along the distance of 153 km through the territory of Serbia. For this purpose group organic-geochemical parameters and biomarker compositions were used. All samples contain approximately same amount of OM, which was deposited under uniform, slightly reducing conditions. Based on the distribution of n-alkanes, the origin and type of OM could not be precisely estimated. However, n-alkane patterns ...... markers in determination of origin and type of organic matter in the Tisza river sediments Snežana Štrbac, Gordana Gajica, Aleksandra Šajnović, Nebojša Vasić, Ksenija Stojanović, Branimir Jovančićević Дигитални репозиторијум Рударско-геолошког факултета Универзитета у Београду [ДР РГФ] The use ...

Laboratory testing of fly ash
Fly ash is one of the most common waste materials created by burning of coal. It is composed of smaller particles, consisting mainly of aluminosilicate glass, mullite and quartz, which are collected by electrostatic separators (filter) of gaseous products arising from the combustion of coal.
