Multi-elemental analysis of real water samples from the Požega area, Serbia
Nebojša Pantelić, Jana Štrbački, Ivana Maloparac, Nikola Tomašević, Biljana Dojčinović, Aleksandar Kostić (2022)Cilj ovog rada bio je ispitivanje kvaliteta realnih uzoraka vode za piće, prikupljenih sa teritorije grada Požege i okolnih seoskih naselja. Za određivanje koncentracije makro i mikroelemenata u uzorcima vode korišćena je analitička tehnika induktivno kuplovana plazma sa optičkom emisionom spektrometrijom, ICP-OES. Dobijeni rezultati upoređivani su sa maksimalno dozvoljenim kocentracijama elemenata propisanim nacionalnim Pravilnikom o higijenskoj ispravnosti vode za piće, kao i preporukama Svetske zdravstvene organizacije (WHO) i Američke agencije za zaštitu životne sredine (EPA). Analizirane vode su malomineralizovane ...Nebojša Pantelić, Jana Štrbački, Ivana Maloparac, Nikola Tomašević, Biljana Dojčinović, Aleksandar Kostić.

Crystallography and Surface Oxidation of Stoichiometric Arsenopyrite from Šumadija-Kopaonik Pb-Zn/Polymetallic Ore District (Serbia)
Ivana Jelić, Aleksandar Pačevski, Aleksandar Kremenović, Aleš Šoster, Andreja Šestan, Janez Zavašnik (2023)The behaviour and stability of arsenopyrite largely depend on its crystal structure, but studies of crystallography and structural defects are scarce. For clarification, we investigated a series of natural arsenopyrite crystals from the polymetallic Pb-Zn-(±Cu,Ag,Au,Sb,Bi,W) Šumadija-Kopaonik ore district (Serbia) by powder X-ray diffraction (XRPD). Among them, samples from the Drenjak gold mineralisation showed near-stoichiometric FeAsS composition and were further investigated by conventional and high-resolution transmission electron microscopy methods. TEM revealed abundant planar crystallographic defects and epitaxial surface oxide layer ...Inorganic Chemistry, Condensed Matter Physics,General Materials Science, General Chemical Engineering, crystal structure, FeAsS, oxidation, TEM, XRPD... 2023-10-16 07:35:12 Crystallography and Surface Oxidation of Stoichiometric Arsenopyrite from Šumadija-Kopaonik Pb-Zn/Polymetallic Ore District (Serbia) Ivana Jelić, Aleksandar Pačevski, Aleksandar Kremenović, Aleš Šoster, Andreja Šestan, Janez Zavašnik Дигитални репозиторијум Рударско-геолошког факултета ...

Konceptualni model hidrogeotermalnog sistema šire okoline Brusa - geološki, geofizički i hidrogeološki uslovi / Conceptual model of hydrothermal system of Brus area - geological, geophysical and hydrogeological condition
Dejan Milenić, Ana Vranješ, Marinko Toljić, Ivana Vasiljević, Natalija Radosavljević, Matija Ognjanović (2024)Na širem području Brusa izvedena su naučna multidisciplinarna istraživanja za potrebe ocene geotermalnog potencijala sa zadatkom de9inisanja uslova formiranja geotermalnih i termomineralnih resursa. Interpretacijom podataka zaključeno je da je na predmetnom terenu formiran "hibridni" hidrogeotermalni sistem, koji sadrži elemente sistema u rov-strukturi i elemente konvektivnog hidrogeotermalnog sistema sa rezervoarom u pokrivaču granitoidne intruzije. Sistem čine dva nezavisna hidrogeotermalna rezervoara. Prvi rezervoar formiran je u gornjokrednim krečnjacima na dubini od oko 1550 m.

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 ...Paolo Mancinelli, Vittorio Scisciani, Cristina Pauselli, Gérard M. Stampfli, Fabio Speranza, Ivana Vasiljević.

Proučavanje razvića Bihaćkog i Cazinskog basena primenom gravimetrijskih podataka
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.

Micro- to nanoscale textures of gold in arsenopyrite and scorodite from the As-Au-Bi assemblage of Drenjak locality (Serbia)
Ivana Jelić, Janez Zavašnik, Marina Lazarov, Alena Zdravković, Sabina Kovač, Jovica Stojanović, Aleksandar Pačevski (2023)Arsenopyrite and pyrite are important carriers of Au that is present in the form of microscopic and “invisible” gold. Such gold can be expected to be released upon the process of oxidation of these sulfides. In studied gold mineralization at Drenjak, related to the granitoids of the Oligocene-Miocene Kopaonik Ore District, the main arsenopyrite-pyrite-(bismuthinite) sulfide assemblage was formed in the quartz bodies and partly replaced by scorodite (FeAsO4·2H2O) and Bi-arsenate. With only up to 5 ppm of gold recorded ...Ivana Jelić, Janez Zavašnik, Marina Lazarov, Alena Zdravković, Sabina Kovač, Jovica Stojanović, Aleksandar Pačevski.

A bilingual digital library for academic and entrepreneurial knowledge management
A generic knowledge management process of organization, storage and retrieval of knowledge can suitably be fitted in a digital library. In the digital and knowledge age digital libraries can be used in knowledge management to handle intellectual assets and support knowledge creation.
