Status and tendencies under development and application of underground coal gasification-UCG
Podzemna gasifikacija uglja u Svetu poslednjih decenija doživljava znatnu ekspanziju u istraživanju i razvoju zbog uveliko iskorišćenih ležišta uglja i loših ekoloških efekata (pri sagorevanju u TE) na životnu okolinu. Srbija ima znatne rezerve uglja, a kada bi se za PGU koristile samo vanbilansne rezerve i otkopni ostaci bilansnih, jasno je kakvi bi bili ekonomski (a i energetski i ekološki) efekti. U radu su sagledane aktivnosti u Svetu na tom planu, pa smatramo da ima smisla i potrebe za primenu ove ...David Petrović, Lazar Kričak, Stefan Milanović, Jovan Marković, Nikola Simić.

Microstructural and magnetic properties of electrospun hematite/cuprospinel composites
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 ...Electrical and Electronic Engineering, Condensed Matter Physics, Atomic and Molecular Physics and Optics, Electronic, Optical and Magnetic MaterialsMira Ristić, Aleksandar Kremenović, Michael Reissner, Željka Petrović, Svetozar Musić.

A new evidence for pachyostotic snake from Turonian of Bosnia-Herzegovina
Фосилни налази морских змија из кредних седимената Босне и Херцеговине познати су од пре скоро сто година. У овом раду је приказан нови налаз пахиостотичне змије пронађене у локалном каменолому Дубовац, око три километра северозападно од Билеће. Примерак чини низ од 29 кичмених пршљенова од којих су седам изоловани из седимента. Међу изолованим пршљеновима два најочуванија су својим скоро четвртастим обликом слична пршљеновима Simoliophis rochebrunei али су неурални луци више отечени. Пршљенови и ребра показују висок степен пахиостозе као ...Dragana Đurić, Dragoslav Radosavljević, Dragana Petrović, Miloš Radonjić, Petar Vojnović.

Analiza rizika flotacijskih jalovišta
U Srbiji i u svetu, dogodile su se brojne akcidentne situacije na flotacijskim jalovištima usled havarija. Pojave akcidenata zaslužuju da budu predmet istraživanja u cilju otkrivanja mehanizma njihovog nastajanja, obima i dometa ugrožavanja kako života ljudi tako i životne sredine, kako bi se inicirali zahtevi za projektovanje i ugradnju zaštitnih sistema čija pouzdanosti treba da bude veća od ukupne verovatnoće opasnosti. U ovom radu je dat primer i prikazana je analiza rizika od pojave akcidentnih situacija gde se naglašava ...Sandra Milutinović, Milena Kostović, Ljubiša Obradović, Sanja Petrović, Srđana Magdalinović.

Methods of transportation and discharge of tails to flotation tailings pond
There are different ways of transporting tailings to flotation tailings, this paper presents all of them that are in use in Europe. For conventional storage, tailings are generally discharged from outfalls located along the embankments (dams) of the facility. For surface thickened disposal and paste storage, the tailings are generally discharged from a central location - either through risers or from point sources that are raised during the life of the plant. There is also dry stacking of tailings, ...Sandra Milutinović, Milena Kostović, Ljubiša Obradović, Srđana Magdalinović, Sanja Petrović.

Fuzzy expert analysis of the severity of mining machinery failure
Mining machinery failure is almost an everyday occurrence. Usually the failures bare certain consequences, which require additional financial costs to repair and restore the system to its operational state. The consequences are viewed through negative and damaging effects a failure has on the machine, health and safety of the employees, work environment, and on the environment. The removal of the consequences of the failure requires additional financial investment, which has a negative impact on the company’s business. In order ...Dejan V.

Fuzzy Model for Risk Assessment of Machinery Failures
The main goal of this research was the development of an algorithm for the implementation of negative risk parameters in a synthesis model for a risk level assessment for a specific machine used in the mining industry. Fuzzy sets and fuzzy logic theory, in combination with statistical methods, were applied to analyze the time picture state of the observed machine. Fuzzy logic is presented through fuzzy proposition and a fuzzy composition module. Using these tools, the symmetric position of the ...... of Machinery Failures Dejan V.

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 ...Snežana Jovanović Stević, Snežana Radisavljević, Aleksandar Mijatović, Biljana Petrović, Ana Kesić.
