Assessment of spa mineral water quality from Vrnjačka Banja, Serbia: geochemical, bacteriological, and health risk aspects
Nebojša Đ. Pantelić, Simona Jaćimović, Jana Štrbački, Danijela B. Milovanović, Biljana P. Dojčinović, Aleksandar Ž. Kostić (2019)The goal of this study is to evaluate the quality of seven natural mineral water sources in the Vrnjačka Banja area used in the treatment of various diseases. The 24 macro- and microelements were determined by inductively coupled plasma optical emission spectrometry (ICP-OES). The results show that element content was within allowed limits of concentration, except for B, As, and Se. The evaluated content of these elements can be associated with geological and anthropogenic factors. The sample S6 contains ...Nebojša Đ. Pantelić, Simona Jaćimović, Jana Štrbački, Danijela B.

Differently shaped nanocrystalline (Fe, Y)3O4 and its adsorption efficiency toward inorganic arsenic species
Biljana P Dojčinović, Boštjan Jančar, Lotfi Bessais, Aleksandar Kremenović, Nataša P Jović-Jovičić, Predrag T Banković, Dalibor M Stanković, Miloš Ognjanović, Bratislav V Antić (2019)Herein we report effects of partial substitution of Fe3+ by Y3+ in magnetite (Fe3O4) on morphology and inorganic arsenic species adsorption efficiency of the Fe3−xYxO4 nanoparticles formed. The series of Fe3−xYxO4 (x=0.00, 0.042 and 0.084, labeled as Y00, Y05 and Y10, respectively) was synthesized using co-precipitation followed by microwave-hydrothermal treatment (MW) at 200°C. With increase of yttrium content(xvalue), both the morphological inhomogeneity of the samples and the fraction of spinel nanorods as compared to spinel pseudospherical particles increased.

The Kovin lignite is characterized by high moisture content, medium to high ash yield, medium to high sulphur content and a relatively low gross and net calorific value. The mineralogical composition, and major and trace element contents were determined by X-ray diffraction, scanning electron microscopy with energy dispersive Xray spectroscopy (SEM-EDS) analyses, and inductively coupled plasma optical emission spectrometry (ICP-OES). ...... elements in the Kovin lignite (Serbia) Dragana Životić, Olga Cvetković, Predrag Vulić, Ivan Gržetić, Vladimir Simić, Konstantin Ilijević, Biljana Dojčinović, Suzana Erić, Bogdan Radić, Sanja Stojadinović, Snežana Trifunović Дигитални репозиторијум Рударско-геолошког факултета Универзитета у Београду ...

Geotermalni potencijal pliocensko-kvartarnih sedimenata na teritoriji opštine Zemun
Matija Zorić (2024)Grad Beograd se nalazi na području koje je izuzetno bogato podzemnim vodama i hidrogeotermalnim resursima. Najveće količine podzemnih voda akumulirane su u okviru aluvijalnih peskovito-šljunkovitih sedimenata i krečnjaka tortonsko-sarmatske starosti. Opština Zemun ima najveći geotermalni potencijal od svih Beogradskih opština, čak 57.7% od ukupnog potencijala celog grada Beograda. Master rad je fokusiran na istraživanju i analizi poznatih tehničkih sistema, kao i termotehničkih sistema koji su u upotrebi na teritoriji opštine Zemun.

Одређивање резерви нафтног лежишта „Х“ методом материјал баланса
Александра Петровић (2024)Метода материјалног баланса је кључна техника у процени резерви нафте и гаса у лежиштима која омогућава системско прорачунавање доступних резерви. Циљ ове методе је да се прецизно израчунају количине флуида у лежишту на основу доступних PVT података, података о лежишту и производњи. Резултати примене методе материјалног баланса показују да је она ефикасна у пружању кавнтитативних процена, међутим њена тачност зависи од квалитета улазних података.

Ostvarivanje dobiti pri uvođenju sistema agregatnih zamena na osnovnoj rudarskoj mehanizaciji površinskih kopova EPS
Jedan od osnovnih zadataka na površinskim kopovima uglja je ostvarivanje zadovoljavajućeg vremenskog i kapacitetnog iskorišćenja kontinualnih sistema. Da bi se to postiglo, neophodno je izvršiti izmene u postojećoj strategiji održavanja. Preduslov je uvođenje agregatne zamene vitalnih delova na rudarskim mašinama. Benefiti su višestruki. Očekivani rezultati ovakvog pristupa su: smanjenje zastoja i povećanje vremena rada; direktne materijalne uštede; bolja organizacija rada; racionalizaciju radioničkih i magacinskih kapaciteta; povećanje vrednosti mašina.
