  • 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 ...

  • Mitigating hydrate formation in onshore gas wells: A case study on optimization techniques and prevention

    Milica Ješić, Bojan Martinović, Stefan Stančić, Miroslav Crnogorac, Dušan Danilović (2023)
    Gas wells, particularly those situated onshore, play a vital role in the global energy sector by supplying a significant portion of natural gas. However, operational challenges, notably gas hydrate formation, pose substantial issues, leading to complications such as flowline blockages and unexpected well shutdowns. Gas hydrates, crystalline structures resembling ice, ...

  • Molecular and Isotope Composition of Biomarkers in Immature Oil Shale and its Liquid Pyrolysis Products (Open and Closed System)

    Gordana Gajica, Aleksandra Šajnovic, Jan Schwarzbauer, Aleksandar Kostić, Branimir Jovančićević, Ksenija Stojanović (2021)
    The molecular and isotopic composition of biomarkers in initial bitumen isolated from raw immature oil shale samples from the Lower Miocene Aleksinac Basin (Serbia) and liquid products (LPs) obtained by pyrolysis in open (OS) and closed systems (CS) are studied. The influence of pyrolysis type and variations of kerogen type on biomarkers composition and their isotopic signatures in LPs is determined. The molecular composition of the LPs from the OS pyrolysis is very similar to those in initial bitumen, independently ...

  • Crystallographic, spectroscopic, thermal and computational studies of polymeric cobalt(II)–mellitate complex with 2,2′-bipyridine

    Lidija Radovanović, Dušan P. Malenov, Marko V. Rodić, Aleksandar Kremenović, Jelena Rogan (2021)
    Orange single crystals of new polymeric cobalt(II) complex {[Co(bipy)(H2O)4]2[Co(μ-mell)(H2O)2]·10H2O}n, 1, were synthesized by slow evaporation method at room temperature (bipy = 2,2′-bipyridine, mell = hexaanion of mellitic acid) and its crystal structure was determined by single-crystal X-ray diffraction. The complex 1 was characterized based on elemental analysis, FTIR spectroscopy and thermal (TG/DTA) analysis followed by computational analysis of noncovalent interactions and quantum chemical calculations of interaction energies. In 1, two crystallographically different Co(II) atoms adopt a deformed octahedral geometry, ...

    Transformation of the heating sector is recognized as being essential for ensuring reliable and afordable energy services provided with reduced consumption of energy sources and diminished impact on the environment and less import dependency. The possibility of utilizing energy sources that otherwise would be wasted needs to be considered and treated as a big advantage of district heating systems. Despite many advantages, sewage wastewater heat is still a mostly unused resource at the global level and a totally unused ...

  • Optimizacija površinskog kopa Ciganuša – Škorac

    Vasilije Zejak (2024)
    U radu se govori o značaju optimizacije u savremenom rudarstvu i kako nam to softveri štede vreme, novac i olakšavaju procese planiranja.Konkretno u izradi ovog rada korišćen je softverski paket Whittle.Da bi se optimizacije mogla uspešno sprovesti, potrebno je konstruisati pre svega blok model ležišta kao i definisati niz tehno – ekonomskih parametara. Na osnovu tih podataka definiše se optimalna kontura i dinamika razvoja radova. U skladu sa definisanim podaci i odgovarajućim podlogama definisana je optimalna kontura površinskog kopa Ciganuša ...

  • Hyperpycnites within the Devonian-Carboniferous flysch of the Carpatho-Balkanides (Kostadinovica, eastern Serbia)

    Miloš Radonjić (2020)
    This study presents new discoveries of vascular plants and the trace fossil Dictyodora liebeana (GEINITZ) from the Devonian–Carboniferous Kučaj-Zvonce flysch of the Carpatho-Balkanides and the implications of this fossil association for its sedimentary setting. The occurrence of the described plant debris in a deep-marine environment indicates the presence of hyperpycnites within the siliciclastic turbidites exposed at the Kostadinovica locality. The sedimentological data and the characteristics of the fossil material support the proposed model in which the sediment was at ...
