Postojeće stanje i budući trendovi u preventivnoj zaštiti podzemnih voda Srbije
Vladimir Živanović (2022)Podzemne vode predstavljaju osnovni, a u mnogim zemljama i jedini resurs za javno vodosnabdevanje stanovništva tako da zaštita podzemnih voda predstavlja bitan preduslov za njihovo dugotrajno i održivo korišćenje. Kako u svetu, tako i u Srbiji, zaštita podzemnih voda se najvećim delom svodi na primenu preventivnih mera zaštite. Kod planiranja zaštite većih prostora sve više se koriste metode za ocenu ranjivosti podzemnih voda. Njihova primena je posebno naglašena u karstnim područjima zato što se tu izdvajaju delovi terena sa ...Zaštita podzemnih voda, karte ranjivosti podzemnih voda, karta hazarda, karte rizika od kontaminacije, monitoring podzemnih voda, SrbijaVladimir Živanović.

Geochemical evaluation of dolostone deposits in Montenegro: Implications for potential industrial applications
Darko Bozovic, Vladimir Simic, Dragan Radulovic, Slobodan Radusinovic, Vesna Matovic, Anja Terzic (2024)This study presents a unique model for assessing the dependability of continuous parts of combined systems in open-pit mining through the application of fuzzy logic. Continuous sub-systems as part of the combined system of coal exploitation in surface mines have the basic function of ensuring safe operation, high capacity with high reliability, and low costs. These subsystems are usually part of the thermal power plant’s coal supply system and ensure stable fuel supply. The model integrates various independent partial ...примарне сировине, минералогија, физичко-механичка својства, технолошка својства, наука о материјалимаDarko Bozovic, Vladimir Simic, Dragan Radulovic, Slobodan Radusinovic, Vesna Matovic, Anja Terzic.

Asset management and condition monitoring on maintenance of mining equipment lignite mines
Predrag Jovančić (2016)Maintenance strategy, once set, is not permanent. This strategy should be adapted and altered according to the findings, achieved results, variation of mine product prices, changes in the region etc. On the other hand, maintenance strategy should be: safe operation, higher productivity, reduced costs and functionality of complete system. Asset management represents activities through which mine achieves the optimal and sustainable management of its property, in order to meet the plan - realization of production with optimized costs. Therefore, ...Predrag Jovančić.

Analysis Of the Process Of Carbon Capture Utilization And Storage In Underground Reservoirs
John Nyame (2024)The importance of mitigating the effects of global climate change has necessitated an in-depth exploration of innovative strategies to reduce carbon dioxide (CO2) emissions. Among these strategies, Carbon Capture, Utilization, and Storage (CCUS) has emerged as a promising and transformative solution. This master thesis delves into the diverse realm of CCUS processes, aiming to unravel the positives challenges, and opportunities within this dynamic field.
