Assessment of environmental radioactivity and health hazard at Stara Planina region
Slavko Dimovic, Boris Vakanjac, Ivana Jelic, Milena Rikalovic, Vesna Ristic-Vakanjac, Radoje Bankovic (2021)Циљ студије је био да се процени потенцијални ризик од зрачења у близини напуштених рудника уранијума, јаловишта или лежишта уранијума на Старој планини у Србији. За процену ризика одређено је неколико параметара: активност еквивалента радијума, Raeq, екстерни индекс опасности, Hex, брзина апсорбоване дозе гама зрачења, D, годишња ефективна доза на позадинској експозицији гама гама на отвореном, AEDoutdoor и ризик од рака током живота, ELCR. Добијени резултати су показали да сви узорци, осим једног, имају Raeq вредност и до два ...Slavko Dimovic, Boris Vakanjac, Ivana Jelic, Milena Rikalovic, Vesna Ristic-Vakanjac, Radoje Bankovic.

Micro- to nanoscale textures of gold in arsenopyrite and scorodite from the As-Au-Bi assemblage of Drenjak locality (Serbia)
Ivana Jelić, Janez Zavašnik, Marina Lazarov, Alena Zdravković, Sabina Kovač, Jovica Stojanović, Aleksandar Pačevski (2023)Arsenopyrite and pyrite are important carriers of Au that is present in the form of microscopic and “invisible” gold. Such gold can be expected to be released upon the process of oxidation of these sulfides. In studied gold mineralization at Drenjak, related to the granitoids of the Oligocene-Miocene Kopaonik Ore District, the main arsenopyrite-pyrite-(bismuthinite) sulfide assemblage was formed in the quartz bodies and partly replaced by scorodite (FeAsO4·2H2O) and Bi-arsenate. With only up to 5 ppm of gold recorded ...Ivana Jelić, Janez Zavašnik, Marina Lazarov, Alena Zdravković, Sabina Kovač, Jovica Stojanović, Aleksandar Pačevski.

Karst groundwater quantity assessment and sustainability: the approach appropriate for river basin management plans
Veljko Marinović, Zoran Stevanović (2019)As a result of the fact that karstified rocks can accumulate large amounts of high-quality groundwater, karst aquifer is considered, throughout the world, one of the most important types of aquifers. Due to their high permeability, but also vulnerability to pollution, these precious groundwater resources need to be properly evaluated and protected. Taking into account heterogeneity and complexity of the karst environment, it is difficult to propose a uniform algorithm for managing karst groundwater, which causes the necessity to ...Upravljanje karstnim podzemnim vodama, Pritisci na kvantitet voda, Plan upravljanja vodnim resursima, Bosna i Hercegovina, SrbijaVeljko Marinović, Zoran Stevanović.

Избор одговарајуће механичке методе
Анастасија Мирјанић (2024)Експлоатација нафте и гаса кључна је за задовољење глобалних енергетских потреба. Различите методе се користе за ефикасно вађење тих природних ресурса из земљe. Механичке методе експлоатације, које укључују различите врсте пумпи и компресора, играју значајну улогу у овом процесу. У нафтној индустрији, ефикасно вађење нафте и гаса зависи од избора одговарајуће технологије пумпања. Две од најраспрострањенијих технологија су дубинске пумпе са клипним шипкама (енгл. Sucker rod pumps- SRP) и електричне потапајуће пумпе (енгл. Electrical submersible pump- ESP). Овај завршни рад ће ...Анастасија Мирјанић. Избор одговарајуће механичке методе, 2024

Estimating hydraulic parameters for the complex hydrodynamic models
Hydrodynamic models have usually been calibrated manually, by trial-and-error, with different values of hydraulic parameters and hydraulic characteristics of boundary conditions. This method of calibration and estimation of hydraulic parameters requires an extensive knowledge and experience of experts, but whether the resulting solution includes an optimal set of parameters still remains an open question. An optimization method founded upon the Gauss-Marquardt-Levenberg algorithm, along with PEST software based on that algorithm, introduces automation of model calibration with regularization, which substantially ...Dušan Polomčić, Dragoljub Bajić, Jelena Ratković, Bojan Hajdin.

Transboundary groundwater resource management: needs for monitoring the Cijevna River Basin (Montenegro–Albania)
The transboundary Cijevna River Basin shared between Albania and Montenegro has a surface area of 650 km2. It is extremely important for water management, especially in the country of Montenegro which is downstream. Due to the high permeability of both the karst and intergranular aquifers that exist in the basin, the River Cijevna sinks along the length of its riverbed and in summer months it usually dries up completely at the confluence section. Hydrometry surveys undertaken during a drought ...Upravljanje međugraničnim vodama, ranjivost podzemnih voda, monitoring mreža, karstne izdani, Albanija, Crna GoraMomčilo Blagojević, Zoran Stevanović, Milan Radulović, Veljko Marinović, Branislav Petrović.
