Dragana Životić, Olga Cvetković, Predrag Vulić, Ivan Gržetić, Vladimir Simić, Konstantin Ilijević, Biljana Dojčinović, Suzana Erić, Bogdan Radić, Sanja Stojadinović, Snežana Trifunović (2019)geochemical and mineralogical study was performed on lignite samples from the Upper Miocene Kovin deposit, hosting three coal seams. 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). ......

Using gravity data to define structural correlation affecting the formation of Neogene basins
A gravity survey can help to define the structural correlation in the study area. The structures that have influenced the development of Neogene basins can be defined using gravity data. By applying mathematical transformations to gravity data, the geological structures (faults, nappes, etc.) that impacted the formation of Neogene basins can be defined. We have taken the part of the Dinarides as the test region. The paper presents the results obtained using the procedure residual, vertical gradient, and total ...Snežana Ignjatović, Ivana Vasiljević, Branisav Sretković, Milanka Negovanović.

Influence of mono- and two-component organic modifiers on determination of lipophilicity of tetradentate Schiff bases
Ispitivani su uticaji primene mono- i dvokomponentnih organskih modifikatora na određivanje lipofilnosti 12 tetradentatnih Šifovih baza metodom reverzno-fazne tankoslojne hromatografije. Osnovni cilj je da se proceni tip interakcije između posmatranih jedinjenja i komponenti primenjenih hromatografskih sistema i uspostavi neki obrazac ponašanja kako bi se lakše izabrala kombinacija organskih modifikatora koji će simulirati interakciju u biološkim sistemima na osnovu činjenica da iste osnovne intermolekularne interakcije su odgovorne za ponašanje supstanci i u biološkom i u hromatografskom sistemu.

Analysis of the exhaust emissions inventory from auxiliary mining machines
Stevan Đenadić, Aleksandar Mirković, Jovana Mitrović, Filip Miletić, Predrag Jovančić, Dragan Ignjatović (2023)Open-pit coal mines are equipped with a large number of mining machines and vehicles with diesel engines. Due to common daily operation of these machines and vehicles large amounts of exhaust gases which contain numerous pollutants are emitted into the atmosphere. The demand to reduce air pollution induced the activities in developed countries to map and calculate all gases emitted by industries to formulate and select adequate preventive activities. In collaboration with machine manufacturers, emission standards for off-road machines ...Stevan Đenadić, Aleksandar Mirković, Jovana Mitrović, Filip Miletić, Predrag Jovančić, Dragan Ignjatović.

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 ...... destilovanom vodom do vrha piknometra, bez uzorka (m) (c). 18 Na osnovu dobijenih vrednosti masa određujemo specifičnu masu prema formuli (3.1). p = p *(__——) G.) ma+me pr — specifična masa uzorka (g/cm*); pm — stvarna zapreminska masa vode (g/cm?); me — masa uzorka (g); mi- masa piknometra ...
