Synergy between the mineral deposit exploration and geothermal resources assessment on the example of "Valjevo" boron and lithium deposit in Serbia
Nebojša Atanacković, Vladimir Živanović, Ana Vranješ, Sava Magazinović, Marinko Toljić, Ana Arifović, Branislav Potić (2023)Exploration of mineral deposits involves a collection of vast data sets on geological characteristics of the area. These data can largely contribute to the assessment of the geothermal potential, which can lead to an increase in the share of geothermal resources in the energy mix of the extractive industry and the local community.

Surface functional groups and degree of carbonization of selected chars from different processes and feedstock
Marija Ilić, Franz-Hubert Haegel, Aleksandar Lolić, Zoran Nedić, Tomislav Tosti, Ivana Sredović Ignjatović, Andreas Linden, Nicolai D. Jablonowski, Heinrich Hartmann (2022)The knowledge ofthe structural and chemical properties of biochars is decisive for their application as technical products. For this reason, methods for the characterization of biochars that are generally applicable and allow quality control are highly desired.

Fluid inclusion study in quartz of the Rudnik Pb-Zn-Cu-Ag skarn deposit, Serbia
Six types of fluid inclusions were identified in three growth zones of hydrothermal quartz from the Rudnik skarn deposit. In the core zone, primary two-phase fluid inclusions of high (type 1) and moderate salinity (type 2) homogenized to liquid between 350-430 °C and 340-420 °C, respectively. Raman analysis revealed that the vapour phases are a CO2-CH4 gas mixture, with a predominance of CO2.

Production of electricity from coal-fired power plants and accompanying CO2 emissions: comparison of EU-27 and US
Even in the third decade of the 21st century, large power plants are still responsible for more than half of the electricity production in Europe and US. They predominantly use fossil fuels in their work, which results in the emission of pollutants into the air, soil and water. In addition to the production of electric energy, fossil fuels, including coal, are used for industrial purposes. Although the use of coal, especially in the countries of the European Union, is ...... ge ne ra ti on [1 Wh ] 1000 10,0 Pa rt ic ip at io n of co al in el ec tr ic it y pr od uc ti on [% ] 0,0 -- B F.G S-O-S T.O BBB .B -00 85B85BššŠ e a 82 – I I I I I RI :N-BR:Bo-Bo-O5-Bo-o5-Bo:Bso:BOB:Oo5-50:Bo-S0:o-B5-G0:-Bo-B5o:BeB: - Q e q RRRR RRRGSKSSSGSGSGS lss Total ...

Rule-based Automatic Multi-word Term Extraction and Lemmatization
In this paper we present a rule-based method for multi-word term extraction that relies on extensive lexical resources in the form of electronic dictionaries and finite-state transducers for modelling various syntactic structures of multi-word terms. The same technology is used for lemmatization of extracted multi-word terms, which is unavoidable for highly inflected languages in order to pass extracted data to evaluators and subsequently to terminological e-dictionaries and databases. The approach is illustrated on a corpus of Serbian texts from ...... are: (a) a head-noun of a MWT is not masculine, so the adjective simple word lemma (always given in the masculine gender) does not agree with it; (b) a MWT lemma should be in the plural, although singular forms exist for simple word constituents.

Петрологија црвених пешчара источне Србијe
Андреј Марковић (2024)У источној Србији формација црвених пешчара има велико распрострањење и улази у састав многих планина овог дела наше земље. Формацију чине кластичне стене интензивно црвене боје псамитске, ређе псамитско-псефитске структуре и алевритске структуре. Ове стене леже трансгресивно преко старијих пермо-карбонских и карбонских стена, док навише прелазе у доњотријаске седименте. Формација црвених пешчара захвата два појаса унутар Карпато-балканида – унутрашњи и средишњи део. Узорци анализирани у овом раду део су средишњег појаса. Тема завршног рада је петрологија црвених пешчара источне ...... Cp0ouje Kanpnunar Menrop Anjipej MapkonBuh [11/17 TIpod. np Buonera Tajuh Beorpajn, jy.r, 2024. Kowmucuja: 1.

Optimizacija utovarno-transportnih sistema u funkciji planiranja površinskog kopa
Mirjana V. Banković (2018-07-13)Profitabilna eksploatacija sve složenijih ležišta je težak zadatak koji zavisi odtemeljnog procesa analize, planiranja i projektovanja rudnika. Izvodljiv strateškiplan mora da zadovoljava društvena, regulatorna, tehnološka, geometrijska iekonomska ograničenja. Kako bi se postigao osnovni cilj, odnosno profitabilnost iodrživost rudarskog projekta na duži period, neophodno je unapređenjematematičkih modela i informatičke podrške procesima planiranja i optimizacijekoji će omogućiti efikasnu realizaciju ovih ciljeva...tehnološki model, integralni model, planiranje, optimizacija,utovarno-transportni sistem, neto sadašnja vrednost projekta...
