Petrofizička svojstva krečnjaka postamenta spomenika „Pobednik” na Beogradskoj tvrđavi
Dijana Trajković (2024)Spomenik „Pobednik” je podignut 1928. godine na Gornjem gradu Beogradske tvrđave. Spomenik je predstavljen bronzanom muškom figurom sa orlom u desnoj ruci i spuštenim mačem u levoj ruci i delo je vajara Ivana Meštrovića, dok je postament delo arhitekte Petra Bajalovića. Postament je u vidu dorskog stuba sa kanelurama na visokoj kubičnoj bazi i izgrađen je od krečnjaka o čijem poreklu ne postoje zvanični literaturni podaci, ali u korelaciji sa ostalim objektima Beogradske tvrđave, pretpostavlja se da je za ...... nHCTpHOyimHjy H jaBHO caormrraBahbc JIeJIa, H ripepajie, aKo ce HaBeJIe HMc ayTOpa Ha HauHH ojIpebeH ojt crpaHe ayropa H naBaola JuineHIe, duaK H y KOMOpLHJaJIHeC CBpXec.

Interaction of sodium dodecylsulfate (SDS) with homoionic montmorillonites: adsorption isotherms and metal-ion release
The interaction of dodecylsulfate anions (DS−) with homoionic Ca-, Mg-, Ni-, Cu-, Cd-, Pb- and Fe-montmorillonites were investigated. Mg- and Cd-montmorillonite do not adsorb DS−, and an anion exchange at the edges of the clay mineral does not take place. Three different adsorption processes are identified on the other montmorillonites: i) Fe-montmorillonite is covered with amorphous iron hydroxide, and DS−-anions are bound at positively charged sites. ii) On Ca- and Pb-montmorillonite DS− is precipitated as Me(DS)2. iii) On Ni- ...M.

Gate Road Support Deformation Forecasting Based on Multivariate Singular Spectrum Analysis and Fuzzy Time Series
Luka Crnogorac, Rade Tokalić, Zoran Gligorić, Aleksandar Milutinović, Suzana Lutovac, Aleksandar Ganić (2021)Underground mining engineers and planners in our country are faced with extremely difficult working conditions and a continuous shortage of money. Production disruptions are frequent and can sometimes last more than a week. During this time, gate road support is additionally exposed to rock stress and the result is its progressive deformation and the loss of functionality of gate roads. In such an environment, it is necessary to develop a low-cost methodology to maintain a gate road support system. ...deformacije podgrade, lasersko skeniranje, višekanalna singularna spektralna analiza, prognoza, klasterisanje fuzzy vremenskih serija... then the h-step ahead VMSSA forecasts exist and is achieved by the following formula: [ x̂(1)j1 , . . . , x̂(M) jM ]T = [ x̃(1)j1 , . . . , x̃(M) jM ] , ji = 1, . . . , Ni (IM×M −WWT) −1WU∇MT Zh, ji = Ni + 1, . . . , Ni + h , (12) where Zh = [ Z(1) h , . . . , Z(M) h ]T and Z(1) h = [ ...

Inhibitory effect of platinum and ruthenium bipyridyl complexes on porcine pancreatic phospholipase A2
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. Laserska desorpcija/jonizacija uz pomoć matriksa, vremenska masa spektrometrija (MALDI-TOF MS) i fluorescentna spektroskopija korišćeni su za analizu aktivnosti enzima u odsustvu i prisustvu metalnih kompleksa i za ......

Adsorption and Polymerization of Aniline on Cu(II)-Montmorillonite: Vibrational Spectroscopy and ab Initio Calculation
Batch adsorption experiments in the presence of oxygen were performed to study the interlayer reactions of aniline on Cu(II)-montmorillonite in aqueous solutions. At concentrations below a critical value of CC ) 2.6 mmol dm-3 only a colored Cu(II)-aniline complex is formed, characterized by a stability constant of log(Kassoc/dm3 mol-1) ) 1.5. At concentrations beyond Cc aniline polymerizes yielding a dark brown product, which is identified by two vibrational spectroscopy techniques, attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy and ...M.
