  • 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 ...

  • On the distribution modulo 1 of the sum of powers of a Salem number

    Dragan Stankov (2016)
    It is well known that the sequence of powers of a Salem number θ, modulo 1, is dense in the unit interval, but is not uniformly distributed. Generalizing a result of Dupain, we determine, explicitly, the repartition function of the sequence , where P is a polynomial with integer coefficients and θ is quartic. Also, we consider some examples to illustrate the method of determination.

  • Stanje i perspektivnost vodosnabdevanja Obrenovca i naselja opštine posle poplava, 2014. godine

    Bojan Hajdin, Dušan Polomčić, Dragoljub Bajić (2017)
    Obrenovac i okolna naselja su tokom 2014. godine zbog poplava u Srbiji pretpeli veliku materijalnu štetu, a pored brojnih privrednih preduzeća ozbiljno je bio ugrožen i sistem vodosnabdevanja. Izvorište „Vić bare“ za vodosnabdevanje grada u selu Zabrežje, na Savi, u potpunosti je potopljeno, a vodovodna mreža, u pojedinim delovima već veoma stara, dodatno je oštećena. Poslednjih nekoliko decenija kao glavni razlozi za probleme u vodosnabdevanju Obrenovca isticane su nedovoljne rezerve podzemnih voda na izvorištu. Novijim istraživanjima utvrđene su rezerve ...

    M. Misz-Kennan, J. Kus, D. Flores, C. Avila, Z. Büçkün, N. Choudhury, K. Christanis, J.P. Joubert, S. Kalaitzidis, A.I. Karayigit, M. Malecha, M. Marques, P. Martizzi, J.M.K. O'Keefe, W. Pickel, G. Predeanu, S. Pusz, J. Ribeiro, S. Rodrigues, A.K. Singh, I. Suárez-Ruiz, I. Sýkorová, N.J. Wagner, D. Životić (2020)
    Self-heating of coal waste is a major problem in the leading coal-producing and consuming countries, independent of the recent or past coal exploitation history. The phenomenon of self-heating is dependent on many factors such as the properties of organic matter (maceral composition and rank), moisture and pyrite content, climate effects, and storage conditions (shape of the dump or compaction of the coal waste). Once deposited, coal waste undergoes oxidation, which can lead to self- heating with the overall temperatures ...

  • Hypogene karst associated with igneous intrusions and its influence on the subsequent karst evolution in high mountains (Central Andes, Peru)

    Alexander B. Klimchouk, Saša Milanović, Cristian Bittencourt (2021)
    Carbonate rocks of Cretaceous age are wide spread in the Peruvian Andes. The studied area in the eastern part of the Cordillera Occidental, near a large igneous intrusion and a skarn deposit, exemplifies polygenetic and multi-phase karst development. Hypogene karstification is related to a hydrothermal activity associated with a magmatic event at ca. 11-9.7 Ma responsible for the emplacement of the nearby intrusion and related alteration of the carbonate rocks. It has resulted in deep-rooted, laterally isolated stair-case-rising shaft ...

    Марија Живковић, Дејан Ивезић, Бобан Павловић, Дејан Стојановић (2024)
    Производња топлоте у системима даљинског грејања у Републици Србији тренутно се заснива искључиво на процесима сагоревања, с доминантним уделом природног гаса из увоза. Иако су технологије за коришћење обновљивих и алтернативних извора енергије добро познате, њихова примена у системима даљинског грејања у Републици Србији још увек је занемарљива (око 2%). Како би се убрзао и олакшао процес транзиције ка обновљивим изворима енергије и разумело тренутно стање и перспектива, спроведена је анкета међу представницима топлана Србији. Циљ је био ...
