Multiphase evolution of fluids in the Rudnik hydrothermal-skarn deposit (Serbia): new constraints from study of quartz-hosted fluid inclusions
This study presents and discusses first detailed petrographic, microthermometric and Raman spectroscopic data from quartzhosted fluid inclusions at Rudnik Zn-Pb-Cu-Ag skarn deposit (Serbia) and combines them with the information on skarnand ore paragenesis. Three periods in the metamorphic-hydrothermal history of the deposit are recognized: 1) the pre-ore prograde skarn period when garnet-clinopyroxene skarns formed, 2) the syn-ore period that encompasses a retrograde stage marked by epidote and zoisite and a quartz-sulfide stage characterized by quartz, pyrrhotite, sphalerite, galena and ...skarnovska ležišta, rudnik, fludine inkluzije, srpska kenozojska magmatska provincija, Zapadno Tetisjki metalogenetski pojasStefan Petrović, Ronald J.

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.

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.

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.

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.

Развој геолошког информационог система Републике Србије
Геолошки информациони систем Србије (ГеолИСС) је пројектован, првенствено, са намером ефикасног дигиталног архивирања геолошких и њима сродних података. У овом раду је приказана структура базе података као основа за развој геолошки конципираног ГИС-а. Нови, објектно орјентисани (О-О) начин моделирања омогућио је дефинисање самосталних типова објеката, хијерархијски повезаних кроз тополошке и друге релације, чиме је обезбеђена њихова медјусобна интеракција. Објектно оријентисано моделирање извршено је коришћењем унифицираног језика моделирања (UML) и CASE алата, кроз концептуални и логички ниво.

Complex geophysical survey on solving the problem of water loss in the karst terrain reservoir
Branislav Sretković, Dejan Vučković (2023)Geophysical surveys in karst terrain are always a specific challenge. Each of them requires a careful consideration of the problem, specific conditions on the ground, the selection of adequate methods applicable in that specific and unique karst area. But they should have one thing in common: a complex approach and looking at the problem from wider to narrower, with a gradual narrowing of the investigation area, increasing the spatial precision and resolution of the obtained data.

Geothermal potential, chemical characteristic and utilization of groundwater in Serbia
To collect and unify data about all geothermal resources in Serbia, a database was formed. The database allows us to perceive the geothermal resources of Serbia and their potential for utilization. Based on the data available in the geothermal database, the estimated temperatures of reservoirs, heat power, and geothermal energy utilization were calculated. The database contains 293 geothermal records (springs, boreholes) registered at 160 locations, with groundwater temperatures in the range between 20 and 111 °C.

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.

Application of Peleg model on mass transfer kinetics during osmotic dehydratation of pear cubes in sucrose solution
Vesna Pavelkić, Tanja Brdarić, Marija Petrović, Gavrilo Šekularac, Milica Košević, Lato Pezo, Marija Ilić (2015)The applicability of Peleg model was investigated for predicting mass transfer kinetics during the osmotic dehydration (OD) process of pears, at different concentrations (40, 60 and 70%, w/w) and temperatures (20, 35 and 50 °C) of sucrose solution. Increase in sucrose solution concentration resulted in higher water loss (WL) and solid gain (SG) values through the osmotic treatment period. After 360 min of osmotic treatment of pears, WL ranged from 23.71 to 31.68% at 20 °C, from 24.80 to ...Vesna Pavelkić, Tanja Brdarić, Marija Petrović, Gavrilo Šekularac, Milica Košević, Lato Pezo, Marija Ilić.

Optimizacija ugla nagiba generalne kosine unutrašnjeg odlagališta površinskog kopa Tamnava-Zapad
Formiranje geomehanički tabilnih unutrašnjih odlagališta otkrivke ima izuzetno značajnu ulogu pri projektovanju i planiranju razvoja površinskih kopova uglja sa aspekta preraspodele masa otkrivke, dinamike eksploatacije, ekoloških zahteva, rudarskih rizika i troškova. Uvećanje zavodnjenosti unutrašnjeg odlagališta otkrivke površinskog kopa Tamnava-Zapadno Polje, kao posledica globalnih klimatskih promena sa pojavom katastrofalnih obimnih padavina i velike poplave, dovelo je i do značajnih ali i trajnih promena geomehaničkih karakteristika materijala, umanjenja stabilnosti generalne kosine unutrašnjeg odlagališta i znatnog povećanja rudarskog rizika.
