Fluid inclusion study in quartz of the Rudnik Pb-Zn-Cu-Ag skarn deposit, Serbia
Six types of fluid inclusions were identified in three growth zones of hydrothermal quartz from the Rudnik skarn deposit. In the core zone, primary two-phase fluid inclusions of high (type 1) and moderate salinity (type 2) homogenized to liquid between 350-430 °C and 340-420 °C, respectively. Raman analysis revealed that the vapour phases are a CO2-CH4 gas mixture, with a predominance of CO2. The core contains and dispersed vapour-rich fluid inclusions of low salinity (type 3) composed of CO2-CH4-H2S ...Stefan Petrović, Ronald J. Bakker, Vladica Cvetković, Rade Jelenković.

The Impact Assessment of NO2 Emission from District Heating Plant on Local Air Quality, the Case of Zemun, Belgrade
The Belgrade district heating system relies on fossil fuels in heat production, where natural gas has the largest share of around 95% and fuel oil with around 4.4%. The Zemun heating plant is completely fueled with fuel oil. Currently, it is the largest plant that is not fueled with natural gas. The objective of this paper is to assess the impact of NO2 from the Zemun heating plant on local air quality by analyzing and comparing the concentration of ...NO2, Zagađenje vazduha, Kvalitet vazduh na lokalnom nivou, Model disperzije, AERMOD, Daljinsko grejanje, BeogradBoban Pavlović, Uroš Pantelić, Marija Živković, Dejan Ivezić.

Analysis Of the Process Of Carbon Capture Utilization And Storage In Underground Reservoirs
John Nyame (2024)The importance of mitigating the effects of global climate change has necessitated an in-depth exploration of innovative strategies to reduce carbon dioxide (CO2) emissions. Among these strategies, Carbon Capture, Utilization, and Storage (CCUS) has emerged as a promising and transformative solution. This master thesis delves into the diverse realm of CCUS processes, aiming to unravel the positives challenges, and opportunities within this dynamic field. The analysis begins with a systematic examination of carbon capture technologies, encompassing post-combustion, pre-combustion, and oxy-fuel combustion ...... strippers and intercooled absorbers could offer a competitive CO--capture solution[39].

Availability as a dimension of energy security in the Republic of Serbia
Boban Pavlović, Dejan Ivezić (2016)There is a range of modern approaches and models in literature for the evaluation and determination of energy security, which are based on different parameters and indicators. For most of them, a common characteristic is emphasizing the avail ability of energy, as an important dimension for ensuring energy security. In this paper, concise overview of Serbian energy sectors is given and appropriate energy indicators are defined and determined. Selected indicators provide insight into the main components that characterize availability ...... natural gas, this indicator is very important because it shows the ability of the country to maintain strategic stocks of critical fuels – oil [12] and natural gas [13]. 2 Oil stockSOS (Oil) 0.086 (8,6%) Oil consumption = = (2) 2 Natural gas stockSOS (Natural gas) 0.2227 (22.3%) Natural gas consumption ...

DFT study of free radical scavenging activity of erodiol
Zoran Marković, Jelena Đorović, Milan Dekić, Milanka Radulović, Svetlana Marković, Marija Ilić (2013)Antioxidant activity of erodiol was examined at the M05-2X/6-311+G(d,p) level of theory in the gas and aqueous phases. The structure and energy of radicals and anions of the most stable erodiol rotamer were analyzed. To estimate antioxidant potential of erodiol, different molecular properties were examined: bond dissociation enthalpy, proton affinity together with electron transfer energy, and ionization potential followed by proton dissociation enthalpy. It was found that hydrogen atom transfer is the prevailing mechanism of erodiol behavior in gas; ...Zoran Marković, Jelena Đorović, Milan Dekić, Milanka Radulović, Svetlana Marković, Marija Ilić.
