Waste rocks and medieval slag as sources of environmental pollution in the area of the Pb-Zn Mine Rudnik (Serbia)
Alena Zdravković, Vladica Cvetković, Kristina Šarić, Aleksandar Pačevski, Aleksandra Rosić, Suzana Erić (2020)The new geochemical and mineralogical data of soil and water from the Pb-Zn Rudnik Mine area (central Serbia) reveal that the areas close to the mining sites and those located remotely from them are both affected by significant pollution by toxic elements, especially As, Pb, Ni and Cr. We, therefore, propose that two main sources are generally responsible for the current state of pollution in this area. The first is the material from waste rock dumps (WRDs) in which ...Alena Zdravković, Vladica Cvetković, Kristina Šarić, Aleksandar Pačevski, Aleksandra Rosić, Suzana Erić.

Integrisano okruženje za pripremu paralelizovanog korpusa
Razvoj paralelizovanih korpusa zahteva pripremu paralelnih tekstova za njihovu integraciju u paralelizovani korpus. Reč je o jednom kompleksnom zadatku koji se može rešiti na različite načine, i koji mora da se odvija u nekoliko koraka. U ovom radu najpre je iznet postupak pripreme paralelnih tekstova za paralelizovani korpus koji se koristi u Grupi za jezičke tehnologije Univerziteta u Beogradu. Potom je dat kratak pregled programa (XAlign, Concordancier, WS4LR), odnosno softverskih alata koji se pri tome koriste.

Development of the hybrid MCDM model for evaluating and selecting bucket wheel excavators for the modernization process
This paper presents a methodology for evaluating and ranking different bucket wheel excavators (BWE) for determining which machine should enter in the process of revitalization and modernization. Various multicriteria methods are used. Combining them achieves the best effect when choosing BVE for the modernization process. AHP, TOPSIS, VIKOR, and PROMETHEE methods are used. The hybrid models are developed from the multi-criteria decision making (MCDM) methods and they are used to evaluate the basic indicators that characterize the operation of ...Snezana Savkovic, Predrag Jovancic, Stevan Djenadic, Milos Tanasijevic, Filip Miletic.

Characterization of bituminite in Kimmeridge Clay by confocal laser scanning and atomic force microscopy
Paul C. Hackley, Jolanta Kus, João Graciano Mendonça Filho, Andrew D. Czaja, Angeles G. Borrego, Dragana Životić, Brett J. Valentine, Javin J. Hatcheries (2022)This work investigates bituminite (amorphous sedimentary organic matter) in Upper Jurassic Kimmeridge Clay source rock via confocal laser scanning microscopy (CLSM) and atomic force microscopy (AFM). These petrographic tools were used to provide better understanding of the nature of bituminite, which has been historically difficult to identify and differentiate from similar organic matter types in source rocks. As part of an International Committee for Coal and Organic Petrology (ICCP) working group, an immature (0.42% vitrinite reflectance), organic-rich (44.1 wt% ...Битуминит, Kонфокална ласерска скенирајућа микроскопија, Mикроскопија атомских сила, Органска петрологија, Термичка зрелостPaul C.

The Late Devonian contraction along the Precaspian Basin north margin: Transpressional range building in the intracratonic domain
Novak Novčić, Marinko Toljić (2023)The evolution of intraplate sedimentary basins located in the vicinity of an active convergent plate boundary is often controlled by the collisional dynamics of the adjacent orogen. The transfer of compression from the orogen to the platform's interior results in the formation of complex structural geometry and kinematics that often reactivate older crustal faults, focus far-field stresses and control the evolution of associated sedimentary basins. One place where this localisation can be optimally understood is the Precaspian Basin, situated ...Intrakratonske deformacije, transpresija, kosa kompresija, krustalni rasedi, intrakratonski transfer stresa, kontrakcioni blokoviNovak Novčić, Marinko Toljić.

Towards the semantic annotation of SR-ELEXIS corpus: Insights into Multiword Expressions and Named Entities
Овај рад представља активности на развоју корпуса ELEXIS-sr, српском додатку вишејезичном анотираном корпусу ELEXIS-а, који се састоји од семантичких анотација и репозиторија значења речи. ELEXIS је паралелни вишејезични анотирани корпус на десет европских језика, који може да се користи као вишејезички репер за евалуацију европских језика са мање и средње развијеним ресурсима. Фокус овог рада је на вишечланим изразима и именованим ентитетима, њиховом препознавању у скупу реченица ELEXIS-sr и поређењу са анотацијама на другим језицима.
