  • Просторна анализа епикарста у оквиру карстног система источног дела Суве планине

    Бранислав Петровић, Зоран Стевановић, Вељко Мариновић, Снежана Игњатовић (2022)
    Епикарст представља највиши део стенске масе који је изложен карстификацији, при чему су главне карактеристике епикарста акумулирање подземне воде и стварање услова за формирање концентрисаних токова у подини ове зоне. У досадашњој пракси истраживања епикарста углавном су коришћене индиректне методе: даљинска детекција, анализа хидрограма карстних врела, хидрохемијске и изотопске анализе, па чак и опити трасирања, док је са друге стране јако мали број истраживача изучавао епикарст директним теренским истраживањима. У раду je приказана иновирана методологија истраживања епикарста, која користи ...

  • Phase relations and physical indicators of municipal waste from old landfills in Serbia

    Dragoslav R Rakić, Irena G Basarić Ikodinović, Jovana M Janković, Tina D Đurić (2021)
    Due to certain similarities of municipal waste and soil, usually for the determination of basic parameters of physical state, laboratory and field tests which are common in geotechnical investigations are used. It is often to construct an apparatus for special purpose to perform some specific laboratory and field tests. Therefore, different values of indicators of municipal waste physical state can be found in the literature. The basic reasons should be found in different definitions and methods that researchers use ...

    Boban S. Pavlović (2022)
    Aktuelnu energetsku tranziciju odlikuje ubrzanje procesa dekarbonizacije energetskih sistema, unapređenje energetske efikasnosti, razvoj čistijih tehnologija baziranih na obnovljivim izvorima energije i održivije korišćenje prirodnih resursa. Da bi se napravio ovako krupan zaokret u postojećim energetskim sistemima, osim promene postojećih tehnologija, potrebno je u planiranje energetske tranzicije uključiti i političke, sociološke, ekonomske i ekološke aspekte, a pre svega obrasce ponašanja i donošenja odluka krajnjih potrošača.

  • Synergy between the mineral deposit exploration and geothermal resources assessment on the example of "Valjevo" boron and lithium deposit in Serbia

    Nebojša Atanacković, Vladimir Živanović, Ana Vranješ, Sava Magazinović, Marinko Toljić, Ana Arifović, Branislav Potić (2023)
    Exploration of mineral deposits involves a collection of vast data sets on geological characteristics of the area. These data can largely contribute to the assessment of the geothermal potential, which can lead to an increase in the share of geothermal resources in the energy mix of the extractive industry and the local community. On the example of the "Valjevo" B-Li deposit, data on structural settings and previous hydrogeological investigations were combined with the results of resource drilling and geophysical ...

  • Defining location and dip of magnetic anomaly sources applying mathematical transformation

    Snežana Ignjatović, Milanka Negovanović (2022)
    It is significant to define the location and dip of anomaly sources during the geophysical exploration (magnetic, gravity, electric, seismic, etc.). In this paper we presented results obtained during magnetic survey. Applying different method of mathematical transformations on magnetic data we can find the position (edge) and dip of magnetic anomaly sources. For successful solution of this problem, we used combination two method tilt derivative and upward continuation. The study area located in the eastern Serbia, north part of ...
