Tectonic evolution of the Vršac Mts. (NE Serbia): Inferences from field kinematic and microstructural investigations
The Vršac Mts. in NE Serbia represent the key area to investigate structural relations between the Northern Serbo-Macedonian Subunit and Supragetic Unit of the Dacia Mega-Unit. The geodynamic events during the Variscan orogeny in the Late Paleozoic colligated the two units and led to their metamorphic differentiation. The Late Cretaceous extension exhumed the medium-grade Serbo-Macedonian metamorphic rocks and structurally juxtaposed them against the low-grade metamorphosed basement of the Supragetic Unit along an E-dipping shear zone, which outcrops in the ...severna srpsko-makedonska subjedinica, supragetikum, kinematska analiza, multifazna ekstenzionalna deformacija...

Long-term planning methodology for improving wood biomass utilization
The insufficiently developed forest management system is often followed by undeveloped forest resources supply chain and insufficient institutional support. These cause inefficient usage of fuel-wood as well as huge amounts of unused forest residues. In order to achieve optimal and long-term sustainable utilisation of biomass, an original methodology based on the interaction of mathematical optimization and backcasting approach has been developed. Mathematical optimization is used for both generation and consideration of techno-economic parameters of the forest biomass supply chain. ...Vladimir Vukašinović, Dušan Gordić, Marija Živković, Davor Koncalović, Dubravka Živković.

Tina Kamčeva, Jörg Flemmig, Bojana Damnjanović, Jürgen Arnhold, Aleksandar Mijatović, Marijana Petković (2011)Fosfolipaza pankreasa A2 (PLA2) igra važnu ulogu u ćelijskoj homeostazi kao iu procesu karcinogeneze. Efekti metalo-lekova koji se koriste kao hemoterapeutici na aktivnost ovog enzima nisu poznati. U ovom radu, interakcija između PLA2 svinjskog pankreasa i dva odabrana kompleksa prelaznih metala — tetrahloro(bipiridin) platine(IV) ([PtCl4(bipi)]) i dihloro (bipiridin) rutenijum(III)hlorida ([RuCl2(bipi)2) ]Cl)—proučavana je.

Equilibrium and kinetic studies of the reactions between [Ru(terpy)(bipy)Cl]Cl complex and biologically important N-donor ligands
Studije u oblasti antikancerogenih karakteristika jedinjenja rutenijuma(III/II) izazivaju veliku pažnju već nekoliko godina otkako su neka od njih kao što su KP1019 (indazolijum-tetrahloridobis(H-indazol)rutenat(III)) i NAMI-A (imidazolijum) -trans-tetrahlorido(dimetilsulfoksid)indazolerutenat(III)) dostigao nivo kliničkog ispitivanja. Kompleksi rutenijuma u reakciji sa molekulom DNK formiraju prvenstveno gvanin- i adenin-adukt, kao komplekse platine. Takođe, nekoliko studija ukazuje na veoma jake interakcije sa proteinima. Međutim, kompleksi Ru(III/II) pokazuju generalno manje toksične efekte od lekova platine(II).1 Proučavali smo kinetiku reakcija supstitucije kompleksa [Ru(terpi)(bipi)Cl]Cl sa biološki važnim ligandima: dimetilsulfoksidom, gvanozin-5’-monofosfatom, ...Aleksandar Mijatović, Biljana Petrović, Ratomir Jelić, Živadin Bugarčić.

Geostatički proračuni sanacije klizišta šipovima
U ovom radu su, polazeći od rezultata geotehničkih istraživanja, prikazani geostatički proračuni sanacije klizišta vertikalnim šipovima. Metodologija proračuna je složena, jer podrazumeva interakciju klizišta i stabilizirajućih šipova. Stoga se simultano analiziraju stabilnost klizišta i stabilnost šipova. Prilikom određivanja bočne otpornosti tla oko šipova koristi se metoda Brinč Hansena koja uzima u obzir trodimenzionalne uslove u tlu i može da se primeni u složenim geološkim uslovima koji su česti u Srbiji. Analize stabilnosti klizišta vrše se odgovarajućim metodama granične ravnoteže. ...sanacija klizišta, interakcija klizišta i šipa, bočna otpornost šipova, stabilnost klizišta i šipova... uslova da se superponiraju otpori tla duž klizne površine i otpori koji su posledica interakcije šipa i okolnog tla.
