  • The influence of structural modification of Pd(II) pincer-type complexes on the kinetics of substitution reactions

    Snežana Jovanović Stević, Snežana Radisavljević, Aleksandar Mijatović, Biljana Petrović, Ana Kesić (2023)
    This mini-review summarizes the kinetic data obtained for the substitution reactions of some palladium(II) complexes containing bis-pyrazolylpyridine derivatives as pincer-type ligands with biologically significant nitrogen- and sulfur-donor biomolecules as nucleophiles. Three structurally different palladium(II) complexes were selected: [Pd(L1)Cl]+ (Pd1), [Pd(L2)Cl]+ (Pd2) and [Pd(L3)Cl]+ (Pd3) (where L1 = bis(2-(1H-pyrazol-1-yl)ethyl)amine, L2 = 2,6-bis(5-(tert-butyl)-1H-pyrazol-3-yl)pyridine, and L3 = 2,6-bis(5-(tert-butyl)-1-methyl-1H-pyrazol-3-yl)pyridine, while for the entering nucleophiles were used thiourea (Tu), L-methionine (L-met), and guanosine-5’-monophosphate (5’-GMP). Kinetic measurements were carried out for all systems as pseudo-first ...

  • Connections between the Levant and the Balkans in the late Middle Pleistocene: Archaeological findings from Velika and Mala Balanica Caves (Serbia)

    Dušan Mihailović, Steven L. Kuhn, Katarina Bogićević, Vesna Dimitrijević, Ana B. Marín-Arroyo, Jelena Marković, Norbert Mercier, Bojana Mihailović, Mike W. Morley, Predrag Radović, William J. Rink, Senka Plavšić, Mirjana Roksandić (2022)
    Major changes in the technological, economic, and social behavior of Middle Pleistocene hominins occurred at the onset of the Middle Paleolithic, 400e200 ka. However, until recently it was not possible to establish when, where, and how certain forms of Middle Paleolithic behavior appeared and spread into Southeastern Europe, mainly owing to gaps in the Paleolithic record. Here we report new results of dating, material culture, and the archaeological context of finds from the Balanica Cave Complex in Sicevo (Serbia). ...

  • Clockwise vertical-axis rotation in the West Vardar zone of Serbia: Tectonic implications

    Vesna Lesić, Emo Márton, Violeta Gajić, Dragana Jovanović, Vesna Cvetkov (2018)
    The Vardar-Tethyan mega-suture between the Eurasian and Adria (Gondwana) margins comprises remnants of oceanic lithosphere of Neotethys and distal parts of the adjacent continental margins including unconformable Late Cretaceous sedimentary cover and Cenozoic igneous rocks of post-obduction age. This study provides kinematic constraints for displacements and rotations affecting the Serbian part of the West Vardar and Jadar-Kopaonik units after the closure of the Neotethyan (= Sava) Ocean. The targets of the paleomagnetic research were Late Cretaceous sediments representing an ...

  • Tektono-termalna evolucija kontakta Dinarida i Karpato-Balkanida u području Jastrepca

    Dalibor Erak (2019)
    Predmet istraživanja doktorske disertacije je tektonska evolucija područja planine Jastrebac u centralnoj Srbiji, gde višefazna tektonska aktivnost od mezozoika do danas komplikuje rekonstrukciju strukturnih odnosa i geološke evolucije ovog prostora. Kompleksna višefazna evolucija planine Jastrebac u Srbiji je demonstrirana kombinovanjem kinematskih podataka prikupljenih na terenu i mikrostrukturnih opservacija sa dodatnim termohronološkim podacima “fission track” i podacima odredbe starosti metodom U-Pb na cirkonima. Gornjokredna ekshumacija bila je praćena gornjokredno-eocenskim navlačenjem i magmatizmom vezanim za kontinentalnu koliziju, pri čemu je akreciona ...

    Праћење и анализа концентрација токсичних метала (олово и кадмијум) у земљишту и усевима указују на то да пољопривредно земљиште у Србији углавном није загађено, а квалитет земљишта је природно добар. Због тога су таква земљишта погодна за органску пољопривреду. Сви уочени случајеви контаминације токсичним металима су само локалне природе, а резултат су ђубрива и пестицида, комуналног отпада, издувних гасова, оближњих производних објеката, топионица, рудника, јаловишта итд.

  • Geološke karakteristike neogenih sedimenta na prostoru šire okoline Ledinaca

    Aleksandar Tričković (2024)
    Sagledavanje evolucije neogenih sedimenata na prostoru šire okoline sela Ledinci omogućeno je primenom različitih stratigrafskih metoda na površinskim i potpovršinskim podacima. Za izradu rada korišćene su sedimentološke, biostratigrafske, geofizičke i riftno sekvencione metode, koje su primenjene na površinskim izdancima i bušotinama. Primenom principa riftne sekvencione stratigrafije na podacima dobijenim geofizičkim karotažnim merenjima dobijeni su podaci o vremenu ekstenzije u Panonskom basenu. Pored toga ovi podaci zajedno sa sedimentološkim i stratigrafskim metodama omogućili su izdvajanje depozicionih sredina tokom neogena. Generalno ...

  • Late and post-collisional tectonic evolution of the Adria-Europe suture in the Vardar Zone

    Emő Márton, Marinko Toljić, Vesna Cvetkov (2022)
    The Vardar Zone is a product of the Triassic-Jurassic opening of the Neotethys, Jurassic obduction, Late Cretaceous/Paleogene consumption of the oceanic crust and continental collision. During the last process, the Eastern Vardar Zone was thrust over the Central and eventually both onto the Western Vardar Zone. The present paleomagnetic and structural study provided new results from the first two zones in the Belgrade area. The younger set of data, together with published ones from the third zone, provide firm ...

  • Karst groundwater quantity assessment and sustainability: the approach appropriate for river basin management plans

    Veljko Marinović, Zoran Stevanović (2019)
    As a result of the fact that karstified rocks can accumulate large amounts of high-quality groundwater, karst aquifer is considered, throughout the world, one of the most important types of aquifers. Due to their high permeability, but also vulnerability to pollution, these precious groundwater resources need to be properly evaluated and protected. Taking into account heterogeneity and complexity of the karst environment, it is difficult to propose a uniform algorithm for managing karst groundwater, which causes the necessity to ...

    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.
