  • Differently shaped nanocrystalline (Fe, Y)3O4 and its adsorption efficiency toward inorganic arsenic species

    Biljana P Dojčinović, Boštjan Jančar, Lotfi Bessais, Aleksandar Kremenović, Nataša P Jović-Jovičić, Predrag T Banković, Dalibor M Stanković, Miloš Ognjanović, Bratislav V Antić (2019)
    Herein we report effects of partial substitution of Fe3+ by Y3+ in magnetite (Fe3O4) on morphology and inorganic arsenic species adsorption efficiency of the Fe3−xYxO4 nanoparticles formed. The series of Fe3−xYxO4 (x=0.00, 0.042 and 0.084, labeled as Y00, Y05 and Y10, respectively) was synthesized using co-precipitation followed by microwave-hydrothermal treatment (MW) at 200°C. With increase of yttrium content(xvalue), both the morphological inhomogeneity of the samples and the fraction of spinel nanorods as compared to spinel pseudospherical particles increased. By ...

  • Одређивање оптималних параметара рада бушотина у повременом гаслифту

    Радослава Јованчевић (2024)
    Гаслифт представља механичку методу производње при коме се производна бушотина снабдева гасом под високим притиском, а његова притисна енергија се користи како би се подржао еруптивни рад бушотине или након еруптивног рада, у циљу истискивања заосталог флуида. Два основна типа гаслифта су повремени и континуални гаслифт. У овом раду је детаљније описана метода повременог гаслифт система. Одређивање оптималне количине гаса који се утискује и расподела ограничене количине гаса на групу бушотина представља битан део пројектовања сваког гаслифт система. Главни ...

  • 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, ...

  • Избор одговарајуће механичке методе

    Анастасија Мирјанић (2024)
    Експлоатација нафте и гаса кључна је за задовољење глобалних енергетских потреба. Различите методе се користе за ефикасно вађење тих природних ресурса из земљe. Механичке методе експлоатације, које укључују различите врсте пумпи и компресора, играју значајну улогу у овом процесу. У нафтној индустрији, ефикасно вађење нафте и гаса зависи од избора одговарајуће технологије пумпања. Две од најраспрострањенијих технологија су дубинске пумпе са клипним шипкама (енгл. Sucker rod pumps- SRP) и електричне потапајуће пумпе (енгл. Electrical submersible pump- ESP). Овај завршни рад ће ...

  • Tectonic evolution of the Vršac Mts. (NE Serbia): Inferences from field kinematic and microstructural investigations

    Uroš Stojadinović, Nemanja Krstekanić, Bojan Kostić, Marija Ružić, Aleksa Luković (2021)
    The Vršac Mts. in NE Serbia represent the key area to investigate structural relations between the Northern Serbo-Macedonian Subunit and Supragetic Unit of the Dacia Mega-Unit. The geodynamic events during the Variscan orogeny in the Late Paleozoic colligated the two units and led to their metamorphic differentiation. The Late Cretaceous extension exhumed the medium-grade Serbo-Macedonian metamorphic rocks and structurally juxtaposed them against the low-grade metamorphosed basement of the Supragetic Unit along an E-dipping shear zone, which outcrops in the ...

    In this paper, grandite core with Grs64±1Adr36±1Sps2composition was crystallographically studied. This core represents zone A of the macroscopically visiblefive A–E zones of the optically anisotropic Grs58–64 Adr36–42Sps2 grandite. The applied procedure includes the detailed analysis of the powder diffraction patterns, and the Rietveld refinements of the crystal structures in a series of 18 space groups and two mixtures, which were followed by the comparative analysis of the R-values, site occupancy factors, and the bond lengths and angles. Synthesis of all ...

  • A multi-criteria approach for assessing the potential of renewable energy sources for electricity generation: Case Serbia

    Boban Pavlović, Dejan Ivezić, Marija Živković (2021)
    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 ...

  • Tehnologija izrade i opremanje magacina eksploziva za potrebe ležišta bakra

    Aleksandar Milojević (2024)
    Nakon radova otvaranja i početka eksploatacije, rudno telo bakra velikih rezervi zahteva i veliku količinu eksploziva da bi se ostvario zacrtan kapacitet. Samim tim, neophodno je izraditi funkcionalan magacin eksploziva koji će biti pristupačan svim horizontima i koji će moći da ispuni celokupni kapacitet svih horizonata. Obzirom da će se u magacinu skladištiti eksploziv, on mora ispunjavati specijalne uslove kako bi skladištenje bilo bezbedno.

  • 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 ...
