Хидротермалне промене у издвојеним стратиграфским јединицама у бушотини јужно од Бора
Павле Јовичић (2024)Анализом уступљених узорака из истражне бушотине јужно од Бора, од стране компаније Serbia Zijin Mining, утврђене су хидротермалне промене (алтерације) које прате стратиграфске чланове набушене самом бушотином. Установљене алтерације директно осликавају класично развиће порфирског Cu система, при чему је указано на њихову повезаност са минерализацијом, као и на потенцијалност самог истражног простора којем изабрана бушотина припада.Павле Јовичић.

Отпад из процеса сагоревања угља као сировина за добијање елемената ретких земаља
Бојан Земљак (2024)Због великог броја индустрија у којима се користе ови ресурси, глобална економија се у великој мери ослања на елементе ретких земаља. Елементи ретких земаља су есенцијална сировина — материјал за развој савремених технологија, али у односу на њихову огромну потражњу, њихово вађење је ограничено и повезано је са значајним утицајима на животну средину.

Investigating distant effects of the Moesian promontory: Brittle tectonics along the western boundary of the Getic unit (East Serbia)
In this study, we report evidence for brittle deformation in a part of the Carpatho–Balkan orogen, which is explained in terms of effects of the rigid Moesian promontory of the European plate on fault kinematics in East Serbia. We focus on the westernmost part of the Getic Unit of the East Serbian Carpatho–Balkanides, i.e. the Gornjak–Ravanica Unit, located between two main thrusts that were repeatedly activated from Early Cretaceous to recent times. We combine a new data set on ...Getikum, Mezijska jedinica, Karpato-balkanski orogen, krte deformacije, Gornjačko-ravanička jedinicaAna Mladenović, Milorad D.

Multiple-Criteria Decision-Making in Mine Development Planning
Sanja Bajić (2023)The Borska Reka ore deposit is an experimental location where developed methodologies have been applied. It is the largest ore body within the Bor mining complex, which has been the subject of numerous studies and analyses for more than three decades. The paper focuses on the application of FAHP and the VIKOR method to address ranking of alternatives and select the optimal mining method by means of fuzzy multicriteria optimization.Sanja Bajić.

Kontaktni metamorfizam gornjokrednih sedimentnih stena Rudnika
Kostić N. Bojan (2021)Kontaktni metamorfizam gornjokrednih sedimentnih stena na planini Rudnik ispitivan je na uzorcima iz pet bušotina. Definisano je šest varijeteta krednih stena (protolita) koji čine dve litološke jedinice izgrađene od klastičnog, karbonatnog i klastično-karbonatnog materijala. Vulkanskom aktivnosti na Rudniku formirana su vulkanska tela koja se utiskuju duž slojevitosti sedimentnih stena, a neka ih presecaju u vidu dajkova. Starost ovog vulkanskog događaja određena je na 23.9 miliona godina.

Predeanu, S. Pusz, J. Ribeiro, S. Rodrigues, A.K. Singh, I. Suárez-Ruiz, I. Sýkorová, N.J. Wagner, D. Životić (2020)Self-heating of coal waste is a major problem in the leading coal-producing and consuming countries, independent of the recent or past coal exploitation history. The phenomenon of self-heating is dependent on many factors such as the properties of organic matter (maceral composition and rank), moisture and pyrite content, climate effects, and storage conditions (shape of the dump or compaction of the coal waste). Once deposited, coal waste undergoes oxidation, which can lead to self- heating with the overall temperatures ...M. Misz-Kennan, J. Kus, D. Flores, C. Avila, Z. Büçkün, N. Choudhury, K.

Improving Document Retrieval in Large Domain Specific Textual Databases Using Lexical Resources
Large collections of textual documents represent an example of big data that requires the solution of three basic problems: the representation of documents, the representation of information needs and the matching of the two representations.

A multi-criteria approach for assessing the potential of renewable energy sources for electricity generation: Case Serbia
When assessing the potential of renewable energy alternatives for electricity generation, it is necessary to implement a multi-perspective approach that includes economic, technical, environmental, and socio-political criteria. For the evaluation of criteria and alternatives, the Fuzzy Analytical Hierarchy Process (FAHP) method is applied. The obtained weights are formed according to the values of energy indicators and expert judgments. The use of a fuzzy numerical value scale for the assessment of expert judgments and energy indicators provides a more sensitive ...... analytic hierarchy process.
