  • Анализа режима истицања карстног врела Горњи Душник (Сува планина)

    Александар Танасковић (2024)
    Карстно врело Горњи Душник налази се у истоименом селу у југоисточној Србији, у општини Гаџин Хан. Врело је узлазног типа и дренира западне делове Суве планине.Каптирано је за потребе водоснабдевања Гаџиног Хана, као и села Горњи и Доњи Душник.Током 2023. и 2024. године спроведена су хидрогеолошка истраживања, са циљем дефинисања режима и биланса подземних вода врела Горњи Душник. У ту сврху, коришћени су подаци из два осматрачка периода.Прва осматрања режима истицања је вршио Геозавод, од 1.11.1977. до 31.01.1979. године.Затим су ...

  • Mineragenija i potencijalnost karbonatnih sirovina rudnog reona Bjelopavlića (Crna Gora)

    Darko M. Božović (2016-09-28)
    Karbonatne sirovine, obzirom na geološku građu Crne Gore predstavljaju jednu od najznačajnijih nemetaličnih mineralnih sirovina. U Crnoj Gori postoje brojna leţišta karbonatnih sirovina (arhitektonsko - građevinskog i tehničko - građevinskog kamena) koja su istraţena ili su u eksploataciji, među kojima rudni reon Bjelopavlića zauzima najznačajnije mjesto.Dosadašnja istraţivanja karbonatnih sirovina na ovom području imala su, međutim, prevashodno uzak istraţivački cilj, utvrđivanje rezervi arhitektonsko - građevinskog i tehničko - građevinskog kamena određenog leţišta, ili preliminarna ispitivanja kvaliteta krečnjaka u njima, sa ...

    Even in the third decade of the 21st century, large power plants are still responsible for more than half of the electricity production in Europe and US. They predominantly use fossil fuels in their work, which results in the emission of pollutants into the air, soil and water. In addition to the production of electric energy, fossil fuels, including coal, are used for industrial purposes. Although the use of coal, especially in the countries of the European Union, is ...

In initial bitumen, the n-alkan-2-ones are identified in the range of C12–C33. In LPs from the OS, they are present in the range C10–C33, whereas in LPs ...

The fatty acid methyl esters are present in the range C11–C31 in LPs from the OS, while exclusively odd C17–C23 homologues are detected in LPs from the ...

  • Assessments of effects of implementation of strategic plans for development of Belgrade District heating system

    Dejan Ivezić, Marija Živković, Aleksandar Madžarević, Miodrag Grujić (2020)
    The district heating system (DHS) is one of the key elements of the Belgrade energy system. Overview of the current state and basic characteristics of the DHS are presented in this paper. The focus is on the planned development of DHS and on the analyses of effects of realization of measures and projects defined by strategic documents related to DHS which are adopted by city authorities (Development Strategy of DHS and Strategy of Belgrade Development). Two exploratory scenarios were ...
