  • 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...

  • Geofizičko reflektivno sondiranje kao test integriteta betonskog šipa

    Jovo Jakišić (2024)
    Temelj predstavlja izuzetno bitan element svakog građevinskog objekta. Zbog toga je neophodno poštovati odgovarajuće standarde, u projektovanju i izvođenju temeljne konstrukcije.Šipovi predstavljaju jedan od načina dubokog fundiranja tj. temeljenja. Za svaki izvedeni šip pojedinačno neophodno je izvesti kontrolu kvaliteta. Postoji više postupaka kojima je mogućeizvršiti kontrolu kvaliteta, a jedan od njih je test integriteta šipa malom silom, koji je prikazan u ovom radu.Ovaj postupak se izvodi seizmometrijskom metodom, postupkom refleksije, koji je definisan međunarodnim standardom ASTM D5882.Podaci koji su prikazani ...

  • Geotechnical effects of municipal solid waste destruction with different compaction methods

    Jovana M Janković Pantić, Dragoslav R Rakić, Irena G Basarić Ikodinović, Tina D Đurić, Gordana Hadži-Niković (2022)
    Disposal of waste in municipal solid waste landfills is the only way of waste disposal in Serbia, with daily compaction and covering with soil material. Due to less space for the construction of new landfills, it is necessary to use their maximum capacity. Well-compacted municipal solid waste takes up less volume and enables safer storage, so it is useful to previously determine the compaction parameters in the laboratory: maximum dry unit weight (γdmax) and optimal water content (wopt). In ...

  • Bioleaching Process for Copper Extraction from Waste in Alkaline and Acid Medium

    Ivica Ristović, Darina Štyriaková, Iveta Štyriaková, Jaroslav Šuba, Emilija Širadović (2022)
    Flotation wastes are becoming a valuable secondary raw material and source of many metals and semimetals worldwide with the possibilities of industrial recycling. The flotation tailings contain oxide and sulfide minerals that have not been sufficiently stabilized and form acidic mine waters, which in turn contaminate groundwater, rivers, and reservoi6sediments. An effective way to recycle these mine wastes is to recover the metals through leaching. While the focus is on acid bioleaching by iron- and sulfur-oxidizing bacteria, alkaline leaching, ...

  • Smanjenje sleganja plitkih temelja primenom mikrošipova

    Slobodan Ćorić, Dragoslav Rakić (2021)
    Mikrošipovi su šipovi malog prečnika koji se grade tako što se u tlu specijalni postupkom formira bušotina koja se zatim armira i injektira. Njihov prečnik je najčešće 150 – 300 mm, a dužina može da bude i više desetina metara. Mikrošipovi mogu da se grade u svim vrstama tla i mogu da budu vertikalni i kosi. Oni se, stoga, koriste kao zamena za konvencionalne šipove i ankere. Primena mikrošipova u fundiranju predstavlja jedan savremeni način izgradnje i sanacije temelja/objekata. ...

  • Comparative analysis of karst water quality parameters of the Banja spring near Valjevo (Republic of Serbia)

    Jovana Lončar, Jovana Mladenović, Vesna Ristić Vakanjac, Veljko Marinović, Branislav Petrović, Petar Vojnović, Radisav Golubović (2024)
    The monitoring of karst spring release regimes is becoming more and more relevant due to the fact that karst waters are of exceptional quality and most often it is only necessary to chlorinate these waters in order to use them for water supply. In addition to monitoring the discharge regime, it is certainly necessary to establish monitoring of quality parameters that are generally observed sporadically (seasonally or monthly). An example of a well-designed monitoring of quantitative and qualitative parameters ...

  • Curcumin nanonization using an alternative small-scale production unit: selection of proper stabilizer applying basic physicochemical consideration and biological activity assessment of nanocrystals

    Ines Nikolić, Jelena Antić-Stanković, Dragana Božić, Danijela Ranđelović, Bojan Marković, Dominique Jasmin Lunter, Aleksandar Kremenović, Miroslav Savić, Snežana Savić (2020)
    As the number of poorly soluble drugs is increasing, nanocrystals have become very interesting due to wide range of application possibilities. Curcumin was used as a model active ingredient in this work. Even though it has many proven positive effects, due to its physicochemical issues, its possibilities have not been fully exploited. The goal of this work was to select optimal conditions for a top-down method for curcumin nanosuspension production, and to perform their comprehensive characterization applying complementary methodologies: ...

  • 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. The analysis begins with a systematic examination of carbon capture technologies, encompassing post-combustion, pre-combustion, and oxy-fuel combustion ...

    Recent research in the southern Central Balkans has resulted in the discovery of the first Middle Paleolithic sites in this region. Systematic excavations of Velika and Mala Balanica, and Peˇsturina (southern Serbia) revealed assemblages of Middle Paleolithic artifacts associated with hominin fossils and animal bones. This paper focuses on Pesturina Layer 4, radiometrically and biostratigraphically dated to Marine Isotope Stage (MIS) 5, which yielded traces of temporary hunting camps. The remains of large ungulate prey are associated with predominantly ...
