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 ...... 80 0.80 162 424 8 K Bogdašići 0.79 0.21 5.93 0.19 751 411 9 K Bogdašići 1.36 0.27 8.97 0.51 660 414 10 K Bogdašići 0.94 0.31 5.89 0.43 627 420 11 K Pridvorci 4.47 1.70 35.76 0.96 800 394 12 K Pridvorci 5.87 2.19 47.04 1.46 801 400 13 K Todorići 0.85 0.21 6.95 0.33 818 406 14 K Todorići 3.08 1.81 ...

Business Models for Small-scale Biomass Projects Development
Biomass is recognized as the most promising renewable energy source in Serbia. The share of biomass in Serbian final energy consumption is over 10%, but mostly related to traditional use in stoves and ovens. One of the main obstacles for wider implementation of contemporary biomass facilities is the inexperience of consumers and stakeholders in the implementation of “innovative” business models, especially in the cases of small-scale projects. In this paper, three different business models (public utility company, energy cooperative ......

Primena metoda podzemnog otkopavanja sa očuvanjem površine terena
Uroš Mirković (2024)Tema ovog diplomskog rada je primena metoda podzemnog otkopavanja sa očuvanjem površine terena, sa posebnim osvrtom na metodu otkopavanja uz zasipavanje pasta zasipima. Ova metoda omogućava efikasan eksploatacioni proces u podzemnim rudnicima, uz minimalne uticaje na površinu, čime se smanjuju deformacije i sleganja terena iznad eksploatacionih radova. Pasta zasipi, koji se sastoje od mešavine jalovine, vode i cementa, koriste se za popunjavanje ispražnjenih prostorija nakon otkopavanja, čime se obezbeđuje stabilnost okolnih stena i smanjuje rizik od urušavanja.

Equilibrium and kinetic studies of the reactions between [Ru(terpy)(bipy)Cl]Cl complex and biologically important N-donor ligands
Studije u oblasti antikancerogenih karakteristika jedinjenja rutenijuma(III/II) izazivaju veliku pažnju već nekoliko godina otkako su neka od njih kao što su KP1019 (indazolijum-tetrahloridobis(H-indazol)rutenat(III)) i NAMI-A (imidazolijum) -trans-tetrahlorido(dimetilsulfoksid)indazolerutenat(III)) dostigao nivo kliničkog ispitivanja. Kompleksi rutenijuma u reakciji sa molekulom DNK formiraju prvenstveno gvanin- i adenin-adukt, kao komplekse platine. Takođe, nekoliko studija ukazuje na veoma jake interakcije sa proteinima. Međutim, kompleksi Ru(III/II) pokazuju generalno manje toksične efekte od lekova platine(II).1 Proučavali smo kinetiku reakcija supstitucije kompleksa [Ru(terpi)(bipi)Cl]Cl sa biološki važnim ligandima: dimetilsulfoksidom, gvanozin-5’-monofosfatom, ...Aleksandar Mijatović, Biljana Petrović, Ratomir Jelić, Živadin Bugarčić.

Chemo-probe into the mantle origin of the NW Anatolia Eocene to Miocene volcanic rocks: Implications for the role of, crustal accretion, subduction, slab roll-back and slab break-off processes in genesis of post-collisional magmatism
Post-collisional Cenozoic magmatic activity in NW Anatolia produced widespread volcanism across the region. In the Biga Peninsula, in the west, medium-K calc-alkaline to ultra-K rocks with orogenic geochemical signature were emplaced at ~43–15 Ma (Biga orogenic volcanic rocks; BOVR). Volcanic activity in the Central Sakarya region, to the east, is mainly restricted to ~53–38Ma, but also continued during the Early Miocene with small basaltic extrusives (Sakarya orogenic volcanic rocks; SOVR).
