  • Identification of the Best Available Renewable Energy Source for Electricity Production in Serbia

    Boban Pavlović, Dejan Ivezić, Marija Živković (2020)
    Around 2/3 of electricity production in Serbia originates from coal-fired thermal power plants. The most significant domestic coal deposits are lignite deposits, a type of low -quality coal that causes negative health, climate and environmental impacts during the combustion. To reduce those negative impacts on domestic electricity production and to promote environmental awareness, the Serbian Energy Sector Development Strategy and the National Action Plan for Use of Renewable Energy Sources indicate the plan for increasing the share of ...

  • Димензионисање транспортера на спољашњем одлагалишту повшинског копа Западни Костолац

    Петар Миловановић (2024)
    У савременом рударству, површински копови угља наилазе на различите проблеме које треба превазићи зарад добијања потребне количине угља. Као највећи потрошачи овог енергента су термоелектране, на основу овога можемо да закључимо колико су блиско повезани добра и континуирана производња на површинском копу и рад термоелектрана. Са задатком да се обезбеди стабилна и континуирана производња, потребно је да се направи добар одабир транспортера. У овом раду, за димензионисање потребног транспортера са траком, коришћен је програмски пакет Helix.Програмски пакет Helix представља један ...

  • Determining the Availability of Continuous Systems at Open Pits Applying Fuzzy Logic

    Miljan Gomilanović, Miloš Tanasijević, Saša Stepanović (2022)
    This work presents a model for determining the availability of continuous systems at open pits by applying fuzzy logic and fuzzy inference systems. The applied model was formed by the synthesis of independent partial indicators of availability. The model is based on an expert system for assessing the availability of continuous mining systems. The availability of the system, as a complex state parameter, is decomposed into the partial indicators, reliability, and convenience of maintenance, and the fuzzy compositions, used ...

  • Sinteza i karakterizacija vanadata alkalnih metala sa elementima retkih zemalja

    Anđela Jovanović (2024)
    Predmet i cilj pisanja ovog rada su sinteza i karakterizacija vanadata alkalnih metala sa elementima retkih zemalja. Prilikom ovih istraživanja, ispitivan je sistem REE2O3–V2O5–KF, gde REE predstavlja trovalentni katjon izabranih elemenata retkih zemalja (Y, Sm, Eu, Gd, Er, Yb). Ovo istraživanje bazirano je na sintezi kristala, nakon čega su dobijeni kristali posmatrani pod binokularnom lupom, analizirani metodom rendgenske difrakcije na polikristalnom materijalu (XRPD) i metodom skenirajuće elektronske mikroskopije sa energetsko-disperzivnom spektroskopijom (SEM-EDS), kako bi se utvrdile karakteristike dobijenih kristala. ...

  • Microstructural and magnetic properties of electrospun hematite/cuprospinel composites

    Mira Ristić, Aleksandar Kremenović, Michael Reissner, Željka Petrović, Svetozar Musić (2020)
    Phase composition, microstructural and magnetic properties of electrospun hematite/cuprospinel composites were investigated. Samples were synthesized starting with 0 to 10 mol% of copper relative to iron. The round shape of reference electrospun fbres was preserved upon their heating up to 600 °C in air, whereas at 700 °C hollow substructure was additionally formed. In these reference samples the presence of hematite phase was detected by XRPD. A small amount (traces) of Fe3O4 /γ-Fe2O3 was also found, due to the ...

  • The ‘Umka’ landslide

    Uroš Đurić, Dragana Đurić, Miloš Marjanović, Biljana Abolmasov, Ivana Vasiljević (2024)
    We present an in-depth landslide map of the ‘Umka’ landslide near Belgrade, Serbia, at a scale of 1:5000. The map delineates elements at risk, primarily buildings and road infrastructure impacted by the landslide displacements of several cm per year, introduced during frequent reactivation stages. The Main map results from a survey of over 350 buildings and more than 7 km of state and local roads. The acquisition techniques included engineering geological field mapping, building survey, and visual interpretation of ...

  • Kvantitativna ocena režima i bilansa podzemnih voda u aluvijonu Velike Morave od Bagrdana do ušća u Dunavu

    Aleksandar Balubdžić (2024)
    Aluvijalni sedimenti velikih reka raspolažu značajnim količinama podzemnih voda, što je zajedno sa površinskim vodama dozvolilo razvoj naselja i ljudskih aktivnosti. Ovaj razvoj uslovljava veće potrebe za vodnim resursima i njihovim kvalitetom. Sa povećanjem eksploatacije podzemnih voda, uticaj iste je značajniji i može da dovede do opadanja nivoa podzemnih voda i pogoršanja kvaliteta. Aluvijon Velike Morave ima značajno rasprostranjenje, usled čega predstavlja važno ležište izdanskih voda sa velikim eksploatacionim mogućnostima.

  • Stratigraphic implications of the Mio-Pliocene geodynamics in the area of Mt. Avala: new evidence from Torlak Hill and Beli Potok (Belgrade, Serbia)

    Ljupko Rundić, Meri Ganić, Slobodan Knežević, Dejan Radivojević, Miloš Radonjić (2019)
    Mt. Avala is located on the southern margin of the Pannonian basin (SPB), a border zone between the uplifted morphostructures of the Dinarides and Carpathian-Balkanides. Similar to the Pannonian basin, tectonostratigraphic evolution of the Mt. Avala area during the last 23 Ma has is characterized by syn- and post-rifting processes as well as tectonic inversion. Here, we present the results of field investigations of the Miocene‒Pliocene dynamics that led to different spatial positions of the same stratigraphic units (e.g. ...

  • Back-arc underplating provided crustal accretion affecting topography and sedimentation in the Adria microplate

    Paolo Mancinelli, Vittorio Scisciani, Cristina Pauselli, Gérard M. Stampfli, Fabio Speranza, Ivana Vasiljević (2021)
    Supported by evidence of deep crustal sources for the observed magnetic anomalies in Central Italy and by outcropping gabbros in the Croatian archipelago, we model the observed gravity and magnetic anomalies in the Central Adriatic Sea and surroundings. We suggest that the major magnetic anomalies in the area are related to a wide underplating and propose that this volume represents the first stage of the back-arc Adria continental breakup in Early Permian times. During the Palaeotethys-Adria collision, underplating has ...

  • Примена нумеричких метода у моделовању тецишта са освртом на различите реолошке услове

    Јелка Крушић (2023)
    Тецишта су комплексне појаве нестабилности које захтјевају истраживања и испитивањакоја до сада нису рађена код нас у области геотехнике. По механизму, начину активирањаи понашању покренутог материјала се знатно разликују од клизишта. Циљ оведисертације је била примјена нумеричких модела пропагације тецишта на примјеру двијепојаве које су се десиле у Србији као посљедица дјеловања циклона Тамара. Детаљноистраживање тецишта подразумијева теренско картирање, теренска истраживања илабораторијска испитивања одабраних узорака са терена.

  • 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 ...
