  • Utilizing sewage wastewater heat in district heating systems in Serbia: effects on sustainability

    Marija Živković, Dejan Ivezić (2021)
    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 ...

    Kristina Gavrilović (2024)
    Izvorište Krupac se nalazi u jugoistočnom delu Srbije, u blizini grada Pirota i deo je sistema za vodosnabdevanje grada i okolnih mesta. Vrela Krupac 1 i Krupac 2 su gravitaciona karstna vrela, locirana na kontaktu jursko-krednog kompleksa stena sa neogenim naslagama Pirotske kotline, čije su specifičnosti uslova dreniranja, kao i uslova cirkulacije, ispitane hidrohemijskim i izotopskim metodama, kao i opitom obeležavanja ponora Golema dubka. Ustanovljeno je da se radi o mladim vodama i sistemu bez duboke cirkulacije podzemnih voda, ...

  • 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 ...

    Snežana M. ignjatović, Ivana M. Vasiljević, Nevena R. Andrić-Tomašević, Ana S. Mladenović (2024)
    Bihaćki i Cazinski baseni su neogeni baseni, koji pripadaju spoljašnjim Dinaridima i formirani su tokom kasne faze razvoja Dinarida. Ovi baseni su od posebnog interesa zbog svoje geološke prošlosti i potencijalnih strukturnih karakteristika. U istraživanju, primenjeni su gravimetrijski podaci u clju boljeg razumevanja evolucije ovih basena. Primenom različitih postupaka matematičkih transformacija na gravimetrijskim podacima može se ustanoviti gravitacioni uticaj neogenih basena male gustine i mogu se detektovati strukture, koje su potencijalno vezane za njihovo formiranje.

  • Synthesis and characterization of high-pressure and high-temperature sphene (CaTiSiO5)

    Jelena Pantić, Vladimir Urbanovich, Vesna Poharc-Logar, Bojan Jokić, Marija Stojmenović, Aleksandar Kremenović, Branko Matović (2014)
    Sphene (CaTiSiO5), a calcium titanosilicate ceramic has been prepared from a powder mixture of CaCO3, TiO2 and SiO2 using vibro-milling for homogenization and activation of precursors. During the highpressure and high-temperature synthesis (HPS) process at 4 GPa and 1,200 °C, sphene undergoes into phase transition, from room-temperature phase P21/a to high-temperature phase A2/a. Evidence of that structural phase transition is given in this paper using infrared, Raman spectroscopy and X-ray powder diffraction. Rietveld refinement was employed to get the ...

    This study presents a unique model for assessing the dependability of continuous parts of combined systems in open-pit mining through the application of fuzzy logic. Continuous sub-systems as part of the combined system of coal exploitation in surface mines have the basic function of ensuring safe operation, high capacity with high reliability, and low costs. These subsystems are usually part of the thermal power plant’s coal supply system and ensure stable fuel supply. The model integrates various independent partial ...
