  • Agates of the Lece Volcanic Complex (Serbia): Mineralogical and Geochemical Characteristics

    Zoran Miladinović, Vladimir Simić, Nenad Nikolić, Nataša Jović Orsini, Milena Rosić (2024)
    Agate veins and nodules occur in the Lece Volcanic Complex (Oligocene-Miocene) situated in the south of Serbia and occupying an area of 700 km2. This volcanic complex is composed predominantly of andesites, with sporadic occurrences of andesite-basalts, dacites and latites, and features agate formations that have been very little investigated. This study focuses on five selected agate occurrences within the Lece Volcanic Complex, employing optical microscopy, scanning electron microscopy (SEM), X-ray powder diffraction analysis, inductively coupled plasma mass spectrometry ...

  • Proračun osnovnih mehanizama na rotornom bageru ShRs 1300 na PK Polje E

    Luka Nikolić (2024)
    Površinska eksoloatacija ležišta mineralnih sirovina, a posebno uglja (lignita) vrši se primenom različitih rudarskih mašina. U zavisnosti od tipa ležišta, rudarsko-geoloških uslova, ekonomske analize i sl. koriste se sistemi sa kontinualnim ili diskontinualnim načinom rada.Kod kontinualnih sistema, primenjuju se kompleksne rudarske mašine kod kojih se proces odvija neprekidno odnosno bez ciklusa utovara, transporta i odlaganja i najčešće rade u sve tri smene. Rotorni bageri i bageri vedričari, transporteri sa gumenom trakom, odlagači ili deponijske mašine čine tkz BTO ili ...

  • The influence of alkyl polyglucosides (and highly ethoxylated alcohol boosters) on the phase behavior of a water/toluene/technical alkyl polyethoxylate microemulsion system

    Marija Ilic, Franz-Hubert Haegel, Vesna Pavelkic, Dragan Zlatanovic, Snezana Nikolic-Mandic, Aleksandar Lolic, Zoran Nedic (2016)
    The influence of additives (alkyl polyglucoside, Glucopon 600 CS UP and alcohol ethoxylate C18E100) on the behavior of the water/toluene/Lutensol ON 50 (technical oxoalcohol, i-C10E5) microemulsion system as a function of temperature and composition has been investigated. The phase behavior of the microemulsions was determined by vertical sections through the Gibbs phase prism (fish-like phase diagrams). Alkyl polyglucoside shifts the one phase region to lower temperatures compared with water/toluene/Lutensol ON 50 mixtures. This is contrary to the expectation, considering ...

    To investigate the influence of spinel structure and sintering temperature on the functional properties of BaTiO3/NixZn1−xFe2O4 (x = 0, 0.5, 1), NiFe2O4, ZnFe2O4, and Ni0.5Zn0.5Fe2O4 were in situ prepared by thermal decomposition onto BaTiO3 surface from acetylacetonate precursors. As-prepared powders were additionally sintered at 1150 °C and 1300 °C. X-ray powder diffraction (XRPD) and scanning electron microscopy (SEM) coupled with electron dispersive spectroscopy (EDS) were used for the detailed examination of phase composition and morphology.

  • Rangiranja bagera za njihovu revitalizaciju primenom višekriterijumske analize

    Ivan Obradović, Dragan Ignjatović, Ranka Stanković, Ljiljana Ivković (2006)
    Obzirom da je na našim površinskim kopovima trenutno u eksploataciji veći broj rotornih bagera sa sličnim tehničkim karakteristikama i približno istom starošću postavlja se pitanje kako rangirati bagere, i kojim redom da se izvrši njihova revitalizacija. Za ocenu stanja i rangiranje ovako velikog broja bagera najpogodnije se pokazalo korišćenje višekriterijumskih metoda sa višeatributnom ocenom, odnosno bodovanje referentnih indikatora stanja bagera na osnovu ekspertske ocene.

  • 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 ...

  • Adaptive neuro-fuzzy prediction of operation of the bucket wheel drive based on wear of cutting elements

    Filip Miletić, Predrag D. Jovančić, Milos Milovančević, Dragan Ignjatović (2020)
    The capacity of the rotor excavator depends largely on the operation of the subsystem for digging. There is a great contribution to the correct and sharp teeth when the capacity is the highest. In the function of time, the teeth become clogged due to abrasive wear, or changes in their geometric shape. To analyze the bucket wheel drive in depend on wear of the cutting elements in this study adaptive neuro fuzzy inference system (ANFIS) approach was implemented. ANFIS ...
