  • Ionothermal synthesis and crystal structure of a new organic–inorganic hybrid compound:catena-poly[bis(1-ethyl-3-methylimidazolium) [hepta-μ-bromido-pentacuprate(I)]]

    Ljiljana Karanović, Dejan Poleti, Tamara Đorđević (2014)
    A new organic-inorganic hybrid compound, catena-poly[bis(1-ethyl-3-methylimidazolium) [μ5-bromido-tri-μ3-bromido-tri-μ2-bromido-pentacuprate(I)]], {(C6H11N2)2[Cu5Br7]}n, has been obtained under ionothermal conditions from a reaction mixture containing Ba(OH)2•8H O, Cu(OH)2•2H2O, As2O5 , 1-ethyl-3-methylimidazolium bromide and distilled water. The crystal structure consists of complex [Cu5Br7]2- anions arranged in sinusoidal {[Cu5Br7]2-}n chains running along the a axis, which are surrounded by 1-ethyl-3-methylimidazolium cations. Three of the five unique Br atoms and one of the three Cu(I) atoms occupy special positions with half-occupancy (a mirror plane perpendicular to the b ...

  • Procena poroznosti i litologije na osnovu geofizičkih merenja u severoistočnoj Rumuniji

    Manja Grifatong (2024)
    Geofizička karotažna merenja imaju važnu ulogu u određivanju fizičkih i geoloških svojstava delova Zemljine kore. Cilj ovog rada je da se prikaže procena poroznosti i litoloških karakteristika formacije na osnovu rezultata geofizičkih karotažnih merenja. Na osnovu dostupnih podataka izrađeni su dijagrami promene poroznosti sa dubinom i krosplot dijagrami neutronska poroznost – srednja gustina za dve bušotine koje se nalaze na Moldavskoj platformi, u severoistočnoj Rumuniji. Na osnovu ovih dijagrama određene su zone povećane poroznosti i litologija formacija kroz koje ...

  • Analiza rada električnih centrifugalnih pumpi

    Milica Stanojević (2024)
    Ovaj rad analizira rad električne centrifugalne pumpe (ESP) u naftnoj industriji, sa fokusom na problem taloženja kamenca (karbonatnih naslaga) unutar sistema. Električne centrifugalne pumpe (ESP) predstavljaju srce mnogih naftnih bušotina. Njihova visoka pouzdanost i sposobnost rada u zahtevnim uslovima čine ih neophodnim za stabilnu i kontinuiranu proizvodnju.Senzori igraju ključnu ulogu u praćenju rada ESP sistema i detekciji ranih znakova taloženja kamenca. Problem taloženja kamenca je izuzetno značajan, jer može dovesti do smanjenja efikasnosti pumpe, povećanja troškova održavanja, i dugoročnih zastoja ...

  • Quantitative landslide risk assessment in the city of Tuzla

    Miloš Marjanović, Biljana Abolmasov, Cvjetko Sandić, Miralem Mulać, Petar Begović (2021)
    In the climate-changing conditions, geological environment interacts more dramatically with the urban fabric than before. The urbanization is expansive and more aggressive than before, but so are the weather extremes and long-term climate trends. In effect, many processes which can be triggered by either side, nature or engineering, are becoming more pervasive than before, and such is the case with landslides. Dealing and managing landslides requires few crucial steps, starting from collecting data on landslide location and typology – ...

  • Design of a sucker rod pumping system

    Ana Ponoćko (2024)
    For a long time in the history of oil production, sucker rod pumps have been the first and in many cases the only choice when it comes to mechanical extraction methods. Proper selection of each individual element of the system enables optimization, which entails benefits in the form of increased efficiency and reduced costs. The first part of the paper presents the underground and surface equipment of the rod pump and describes the operation of the entire system. The ...

  • Synthesis, magnetic, thermal and structural properties of Co(II), Ni(II) and Cu(II) complexes containing isophthalato ligands

    Jelena Rogan, Dejan Poleti, Ljiljana Karanović, Zvonko Jagličić (2011)
    A series of novel ternary Co(II), Ni(II) and Cu(II) complexes containing 2,20-dipyridylamine (dipya), 2,20-bipyridine (bipy), and 1,10-phenanthroline (phen), as aromatic diamine ligands, and dianion of isophthalic acid (ipht) have been prepared by ligand exchange reactions from diluted H2O/EtOH solutions. The complexes were characterized by elemental analysis, IR spectroscopy, magnetic susceptibility measurements and TG and DSC analysis. Three complexes, Cu(dipya)(ipht)H2O (1), Co(dipya)(ipht)2H2O (2) and Cu(ipht)(phen)2H2O (5) are polymeric with bis-monodentate ipht, while the other two complexes M(bipy)(ipht)4H2O, M@Co(II) (3) and ...

    Aлександар Додеровић (2024)
    Површинска експлоатација минералних сировина захтијева претходно откопавање значајних( милионских) количина јаловине, које је неопходно транспортовати до локације на којој ће сеона трајно одложити. Традиционални приступ избора локације и дизајна одлагалишта се карактерише парцијалним приступом, заснованом на анализи неколико водећих критеријума као и на личном искуству инжењера, често занемарујући синергетски ефекат осталих утицајних фактора Технолошке операције које се односе на манипулацију јаловином, међу којима предњачи транспорт, генеришу највећи дио трошкова у површинској експлоатацији.

  • An update on the mineral-like Sr-containing transition metal arsenates

    Tamara Đorđević, Ljiljana Karanović (2021)
    We report on the crystal structures of three novel synthetic SrM-arsenates (M = Ni and Fe3+), isostructural or structurally related to the minerals from tsumcorite, carminite and brackebuschite groups. They were synthesised under mild hydrothermal conditions and further characterised using single-crystal X-ray diffraction (SXRD), scanning electron microscopy with energy dispersive spectroscopy (SEMEDS) and Raman spectroscopy. SXRD and SEM-EDS yielded formulae: (I) SrNi2(AsO4)2·2H2O, (II) Sr1.4Fe3+ 1.6(AsO4)2(OH)1.6 and (III) SrFe3+(AsO4)(AsO3OH). All three structures are built up of slightly distorted MO6 octahedra ...

    Aligning senses across resources and languages is a challenging task with beneficial applications in the field of natural language processing and electronic lexicography. In this paper, we describe our efforts in manually aligning monolingual dictionaries. The alignment is carried out at sense-level for various resources in 15 languages. Moreover, senses are annotated with possible semantic relationships such as broadness, narrowness, relatedness, and equivalence. In comparison to previous datasets for this task, this dataset covers a wide range of languages ...
