Konceptualni model hidrogeotermalnog sistema šire okoline Brusa - geotermalna karakterizacija sistema / Conceptual model of hydrothermal system of Brus area - system geothermal characterization
Dejan Milenić, Ana Vranješ, Marinko Toljić, Ivana Vasiljević, Natalija Radosavljević, Matija Ognjanović (2024)Postavljeni konceptualni model hidrogeotermalnog sistema Brusa sa širom okolinom testiran je primenom različitih hidrohemijskih i izotopskih metoda u cilju njegove verifikacije i karakterizacije. Rezultati su ukazali na atomsfersko poreklo geotermalnih fluida i na razviće primarnih rezervoara u okviru karbonatnih stena. Prvi rezervoar formiran je u okviru krečnjaka gornjotrijakse starosti, dok drugi rezervoar egzistira u okviru trijskaih mermera. Zone prihranjivanja locirane su u zapadnom delu terena. Sistemi gravitacionih raseda kontrolišu kretanje fluida u sistemu, dok proces jonske izmene dominira u ...Dejan Milenić, Ana Vranješ, Marinko Toljić, Ivana Vasiljević, Natalija Radosavljević, Matija Ognjanović.

Two approaches to compilation of bilingual multi-word terminology lists from lexical resources
In this paper, we present two approaches and the implemented system for bilingual terminology extraction that rely on an aligned bilingual domain corpus, a terminology extractor for a target language, and a tool for chunk alignment. The two approaches differ in the way terminology for the source language is obtained: the first relies on an existing domain terminology lexicon, while the second one uses a term extraction tool. For both approaches, four experiments were performed with two parameters being ...Branislava Šandrih, Cvetana Krstev, Ranka Stanković.

Приказане су доменске специфичности ових ресурса, како се користе, и међусобно употпуњују. Посебно је приказано како се коришћењем доменског корпуса могу екстраховати глаголи специфични за кулинарски домен и описати начини њиховог коришћења.

Mesozoic carbonate rocks in Serbia used as dimension stone
Vesna Matović, Tijana Vojnović Ćalić (2016)The building industry in Serbia uses, to a great extent, imported natural stone for architectural purposes. The significance of local deposits, particularly limestones, is not adequately perceived despite the country’s abundance of these valuable resources. Therefore, this study focuses on Serbia’s Mesozoic carbonate rocks, specifically on the deposits of four selected quarries: Klisura, Skrzut, Struganik, and Tisnica. The quality and prospects of the application of these limestones has not yet been the subject of a detailed, comprehensive investigation. Therefore, ...... Trijarski konoditi Zlatibora.

Prognoza operativne efikasnosti aktivnog podzemnog rudnika zasnovana na teoriji sivih sistema
Svetlana M. Štrbac-Savić (2016-06-10)Efikasnost predstavlja preduslov za opstanak svake rudarske kompanije, posebno u uslovima izuzetno konkurentnog trţišnog okruţenja kao što je to rudarska industrija. Efikasnost oznaĉava sposobnost kompanije da ispuni svoje kratkoroĉne ili dugoroĉne ciljeve. Operativna efikasnost se definiše kao odnos izmeĊu ulaznih parametara potrebnih za odvijanje proizvodnje i pokazatelja dobijenih proizvodnjom.

Influence of mono- and two-component organic modifiers on determination of lipophilicity of tetradentate Schiff bases
Ispitivani su uticaji primene mono- i dvokomponentnih organskih modifikatora na određivanje lipofilnosti 12 tetradentatnih Šifovih baza metodom reverzno-fazne tankoslojne hromatografije. Osnovni cilj je da se proceni tip interakcije između posmatranih jedinjenja i komponenti primenjenih hromatografskih sistema i uspostavi neki obrazac ponašanja kako bi se lakše izabrala kombinacija organskih modifikatora koji će simulirati interakciju u biološkim sistemima na osnovu činjenica da iste osnovne intermolekularne interakcije su odgovorne za ponašanje supstanci i u biološkom i u hromatografskom sistemu.
