Composition of organic matter and thermal maturity of Mesozoic and Cenozoic sedimentary rocks in East Herzegovina (External Dinarides, Bosnia and Herzegovina)
This paper presents the first data on the organic matter and thermal maturity of Mesozoic and Cenozoic sedimentary rocks in the East Herzegovina region of the External Dinarides. Representative, organic-rich samples from outcropping sedimentary rocks of different ages in the area (Triassic to Neogene) were selected and analysed. The organic matter was studied by Rock-Eval pyrolysis and under the microscope in reflected non-polarized light and incident blue light. The results obtained show the presence of different types of organic ...... and thermal maturity of Mesozoic and Cenozoic sedimentary rocks in East Herzegovina (External Dinarides, Bosnia and Herzegovina) Nikoleta Aleksić, Aleksandar Kostić, Miloš Radonjić Дигитални репозиторијум Рударско-геолошког факултета Универзитета у Београду [ДР РГФ] Composition of organic matter ...

Production of electricity from coal-fired power plants and accompanying CO2 emissions: comparison of EU-27 and US
Even in the third decade of the 21st century, large power plants are still responsible for more than half of the electricity production in Europe and US. They predominantly use fossil fuels in their work, which results in the emission of pollutants into the air, soil and water. In addition to the production of electric energy, fossil fuels, including coal, are used for industrial purposes. Although the use of coal, especially in the countries of the European Union, is ......

Energetska bezbednost sektora prirodnog gasa Srbije
U prve dve decenije 21. veka obezbeđivanje sigurnosti snabdevanja prirodnim gasom domaćeg tržišta bio je jedan od prioriteta razvoja energetike Srbije. Istovremeno, aspekt sigurnog snabdevanja bio je neizostavni deo slagalice stvaranja energetske bezbednosti. Izražena uvozna zavisnost je dominantna karakteristika sektora prirodnog gasa, tačnije, Republika Srbija je snažno zavisna od ruskog gasa, sa više od 80% uvezenih količina gasa, a do pre dve godine snabdevala se isključivo kroz jednu interkonekciju. U radu se razmatra aktuelna situacija u sektoru prirodnog ...... bezbednost sektora prirodnog gasa Srbije Aleksandar Madžarević, Predrag Jovančić, Miroslav Crnogorac Дигитални репозиторијум Рударско-геолошког факултета Универзитета у Београду [ДР РГФ] Energetska bezbednost sektora prirodnog gasa Srbije | Aleksandar Madžarević, Predrag Jovančić, Miroslav Crnogorac ...

Structural dissymmetrization of optically anisotropic Grs64±1Adr36±1Sps2 grandite from Meka Presedla (Kopaonik Mt., Serbia)
In this paper, grandite core with Grs64±1Adr36±1Sps2composition was crystallographically studied. This core represents zone A of the macroscopically visiblefive A–E zones of the optically anisotropic Grs58–64 Adr36–42Sps2 grandite. The applied procedure includes the detailed analysis of the powder diffraction patterns, and the Rietveld refinements of the crystal structures in a series of 18 space groups and two mixtures, which were followed by the comparative analysis of the R-values, site occupancy factors, and the bond lengths and angles. Synthesis of all ...Pavle Tančić, Aleksandar Kremenović, Predrag Vulić.

Strategic Environmental Assessment and the precautionary principle in the spatial planning of wind farms – European experience in Serbia
Spatial determination planning is at an initial and very sensitive step in the development of wind farms. On one hand, it is important to maximize the potential of wind in a particular area, and on the other hand, it is important to achieve environmental protection (including the human population and natural heritage) in the same space at the same time. With this in mind, it is important to balance all the requirements that are relevant for reaching the optimal ...Boško Josimović, Aleksandar Cvjetić, Danilo Furundžić.

Digitalizacija u rudarstvu: Kreiranje sistema za efikasno poslovno izveštavanje
Proces donošenja odluka u oblasti rudarstva i geologije uslovljen je blagovremenim posedovanjem kvalitetnih podataka i informacija. Kompleksnost rudarskih procesa nalaže prikupljanje podataka na dnevnom odnosno na smenskom nivou. Podaci kao takvi bez analitičkog pristupa nisu dovoljni. Kako bi pristup podacima bio brz i efikasan neophodno je posedovanje adekvatnog digitalnog rešenja uz adekvatne centralizovane baze podataka.

Sinteza i karakterizacija vanadata alkalnih metala sa elementima retkih zemalja
Anđela Jovanović (2024)Predmet i cilj pisanja ovog rada su sinteza i karakterizacija vanadata alkalnih metala sa elementima retkih zemalja. Prilikom ovih istraživanja, ispitivan je sistem REE2O3–V2O5–KF, gde REE predstavlja trovalentni katjon izabranih elemenata retkih zemalja (Y, Sm, Eu, Gd, Er, Yb). Ovo istraživanje bazirano je na sintezi kristala, nakon čega su dobijeni kristali posmatrani pod binokularnom lupom, analizirani metodom rendgenske difrakcije na polikristalnom materijalu (XRPD) i metodom skenirajuće elektronske mikroskopije sa energetsko-disperzivnom spektroskopijom (SEM-EDS), kako bi se utvrdile karakteristike dobijenih kristala. ...elementi retkih zemalja, sinteza kristala metodom fluksa, vanadati alkalnih metala, rendgenska difrakcija, SEM-EDS metodaAnđela Jovanović.
