  • Petrološke karakteristike dunavskog šljunka (Beograd – Zemun)

    Miloš Mihajlović (2024)
    Dunavski šljunak u okolini Zemuna karakterističan je za obalne rečne naslage formirane dugotrajnim procesima erozije i transporta materijala koje reka Dunav nosi sa različitih područja uzvodno. Ispitivanja šljunka sa lokacije „Gemax” su pokazala je šljunak uglavnom zaobljen, najčešće u rasponu od nekoliko milimetara do nekoliko centimetara u prečniku. Kako Dunav nosi materijal sa velikog sliva, ovaj šljunak sadrži raznovrsne sastojke sa dominacijom kvarca i odlomaka stena visokosilicijskog sastava. Mineraloško-petrografska ispitivanja pokazala su prisustvo klasta različitog sastava, čime je potvrđena ...

  • Развој модела конструкције просторија отварања рудника са подземном експлоатацијом

    Dražana M. Tošić (2016-08-26)
    Приликом израде подземних просторија у стјенској маси долази до нарушавања природне равнотеже напонских стања стијенског масива који су владали прије израде тих просторија, при чему долази до појаве прертасподјеле напона и његове концентрације у појединим правцима и тачкама, односно долази до појаве пластичних деформација које су праћене ломљењем стијенске масе и кретањима материјала према откопаном простору...

  • 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 ...

  • Surface functional groups and degree of carbonization of selected chars from different processes and feedstock

    Marija Ilić, Franz-Hubert Haegel, Aleksandar Lolić, Zoran Nedić, Tomislav Tosti, Ivana Sredović Ignjatović, Andreas Linden, Nicolai D. Jablonowski, Heinrich Hartmann (2022)
    The knowledge ofthe structural and chemical properties of biochars is decisive for their application as technical products. For this reason, methods for the characterization of biochars that are generally applicable and allow quality control are highly desired. Several methods that have shown potential in other studies were used to investigate two activated carbons and seven biochars from different processes and feedstock. The chars were chosen to cover a wide range of chemical composition and structural properties as a hardness ...

  • Примена CNC машина при обради мермера

    Ненад Остојић (2024)
    Мермер је стена настала метаморфизмом седиментних карбонатних стена, најчешће кречњака или доломита. Мермер се углавном састоји од калцита,кречњака, серпентина и доломита. Његове главне компоненте су углавном калцијум карбонат, који чини више од 50 посто, и други магнезијум карбонат, калцијум оксид, манган оксид и силицијум диоксид, итд. Фазе обраде мермера су: примарно резање мермерних блокова у плоче, површинска обрада мермерних плоча, секундарно резање мермерних плоча, терцијарна обрада (ако је потребно). CNC машина је електро-механички уређај који управља алатима, користећи програмирање путем ...

  • Asbestos-Based Pottery from Corsica: The First Fiber-Reinforced Ceramic Matrix Composite

    Philippe Colomban, Aleksandar Kremenović (2020)
    Asbestos-containing pottery shards collected in the northeast of Corsica (Cap Corse) and dating from the 19th century, or earlier, have been analyzed by SEM-EDS, XRPD, FTIR and Raman microspectroscopy. Blue (crocidolite) and white (chrysotile) asbestos fiber bundles are observed in cross-sections. Most of the asbestos is partly or totally dehydroxylated, and some transformation to forsterite is observed to occur, indicative of a firing above 800 C. Examination of freshly fractured pieces shows a nonbrittle fracture with fiber pull-out, consistent with ...

  • A necessary and sufficient condition for an algebraic integer to be a Salem number

    Dragan Stankov (2019)
    We present a necessary and sufficient condition for a root greater than unity of a monic reciprocal polynomial of an even degree at least four, with integer coefficients, to be a Salem number. This condition requires that the minimal polynomial of some power of the algebraic integer has a linear coefficient that is relatively large. We also determine the probability that an arbitrary power of a Salem number, of certain small degrees, satisfies this condition.
