Cytotoxic activity of tetradentate Schiff Base Copper(II) complexes
Istraživanje kompleksa bakra kao potencijalnih antikancerogenih agenasa nudi ohrabrujuće perspektive u odnosu na komplekse platine (II) računajući na smanjenu toksičnost, novi mehanizam delovanja, različit spektar aktivnosti i perspektivu neunakrsne rezistencije. Kompleksi Šifovih baza bakra(II) koji sadrže tetradentatne ligande acac2en tipa (acac2en (1); tfacac2en (3), acactfacacen (4), acacphacacen (6)) pokazali su važnu antioksidativnu aktivnost, visok potencijal za interakciju sa HSA i DNK, u prethodnim studijama. Zbog toga je bilo interesantno ispitati i uporediti potencijal antikancerogene aktivnosti in vitro, u odnosu ...Nevenka Gligorijević, Aleksandar Mijatović, Sandra Aranđelović, Rada Baošić .

Interactions of Copper(II) Complexes of some Schiff base ligands with calf thymus DNA and bovine serum albumin
Joni prelaznih metala u kombinaciji sa različitim ligandima nude veliki broj mogućnosti za ispitivanje potencijalnih bioaktivnosti. Među jonima prelaznih metala, bakar je poznat kao endogeni metal za ljude, sa karakterističnim biološkim redoks aktivnostima i relativno jakim afinitetom za nukleobaze. Kompleksi bakra ispoljavaju svoju antitumornu aktivnost na nekoliko različitih načina, generišu veliku količinu ROS, što uzrokuje oksidativno oštećenje mitohondrija i biomakromolekula. Nađeno je da kompleksi bakra(II) imaju umeren do dobar afinitet vezivanja sa DNK, uglavnom putem interkalacije.Angelina Petrović, Aleksandar Mijatović, Rada Baošić, Jovana Bogojeski.

Characterization of biochar surface functional groups
In this work, biochar originating from paper fibres was examined. Biochar was prepared via pyrolysis method at 550°C. Oxygen-containing functional groups on biochar surface were determined. The surface functional groups of biochar were analysed by Fourier transform infrared spectroscopy. The amount of oxygen-containing functional groups was performed with Boehm titration. The total acidity of biochar was mostly attributed to carboxylic and lactonic groups.Marija Ilić, Vesna Pavelkić, Aleksandar Lolić, Branko Leković.

Mogućnost korišćenјa toplotnih pumpi sa otpadnom toplotom iz postrojenјa za prečišćavanјe otpadnih voda kao toplotnim izvorom
U narednom periodu se planira izgradnja nekoliko desetina sistema za prečišćavanje otpadnih voda u većim gradovima u Srbiji. Iskustva iz postrojenja koja su trenutno u radu, pokazuju da bi prečišćena otpadna voda, s obzirom na protok i temperaturu, mogla da predstavlja značajan izvor obnovljive energije. U radu su prikazani primeri dobre prakse korišćenja ove energije u sistemima daljinskog grejanja u zemljama Evropske unije.

‘Blue-’ and ‘Brown-speckled’ pottery from Qalhât, the Sultanate of Oman (13–16th centuries): Comparison with traditional Omani 19–20 century productions
Representative ‘Blue speckled’ (13–16th centuries) and ‘Brown speckled’ (13–21st century) wares recovered from the excavations in Qalhât or collected around Bahlâ city (Sultanate of Oman) were characterized by XRPD, SEM-EDS, Raman/optical microspectroscopy, and thermal expansion. Minerals present in the body (quartz, augite and albite as major phases, calcite, dolomite, rutile, anatase, phosphate, hematite and magnetite as minor phases) were identified by XRPD and/or Raman spectroscopy. SEM-EDXS microanalysis was performed on the glazes in order to compare their composition, especially ...Liliana Gianni, Hélène Renel, Aleksandar Kremenović, Philippe Colomban.

Environmental Noise Impact Assessment for Large-Scale Surface Mining Operations in Serbia
Noise emissions are a significant environmental impact caused by the mining industry in all technological phases of surface mining, mineral processing, and waste disposal. This paper presents the role of noise impact assessment and control in large-scale surface mining operations. Mine planning develops the model of mining operations, ore excavation, and waste dumping scheduling and processing rates, including spatial distribution of mining activities. Such a level of mine planning requires an environmental impact assessment study. This can be achieved ...Uros Pantelic, Petar Lilic, Aleksandar Cvjetic, Nikola Lilic.

Hydrodynamic analysis application of contaminated groundwater remediation to oil hydrocarbons
U ovom radu sagledana je primena hidrodinamičke analize u okviru odabrane remedijacione metode ,,pumpanja i tretiranja” kontaminiranih podzemnih voda ugljovodonicima, na primeru pretakališta rafinerije nafte u Pančevu. Primenjena hidrodinamička analiza predstavlja pravilan, a sve češće i neophodan pristup u savremenoj hidrogeologiji. Prethodnim hemijskim analizama uzoraka tla i podzemnih voda na istražno-osmatračkim objektima detektovano je zagađenje produktima nafte. Novoizvedena istraživanja obuhvatila su izvođenje 12 pijezometara različitih dubina, geoelektrično sondiranje tla, ,,in situ” merenja prisutnog kontaminanta, izdvojenog kao hidrofobna faza LNAPL, ...Predrag Pajić, Aleksandar Čalenić, Dušan Polomčić, Dragoljub Bajić.

Effect of natural gas composition on methane number: A case of gas reservoirs in Serbia
Natural gas is considered as the most environmentally acceptable fossil fuel, thus it is an alternative to petroleum derivate, dominantly used in internal combustion engines. Physical properties of a fuel as well as behavior during combustion process are affected by its composition. This article presents analysis of effect of natural gas composition on methane number (MN), conducted for natural gas deposits in Serbia.

Possibilities for Reduction of Energy-Related Air Pollution in Serbia - Exploring Energy Scenarios
Fossil fuels and biomass account for almost 93% of the total primary energy supply in Serbia. Meeting the energy needs of consumers implies a transformation of the chemical energy of fuels through combustion processes to obtain heat that can be utilized as such, or further transformed into mechanical or electrical energy. These processes have an undeniable impact on air pollution, even in cases of biofuels or hydrogen combustion. Possibilities for air pollution reduction are identified, both on the supply ...Marija Živković, Boban Pavlović, Dejan Ivezić, Aleksandar Mijatović.

Effect of Properties of Working Fluids on the Efficiency of a Low-Temperature Organic Rankine Cycle
Decarbonization of all segments of energy systems, both on the supply and demand side, is one of the main goals of the energy transition. Electricity supply in the future will largely rely on generation from intermittent energy sources: wind and solar. Locally available, non-utilized alternative low-temperature energy sources as hydro-geothermal wells, and abounded oil and gas wells, have the potential to provide continual energy production over the year. Electricity generation from these energy sources is carried out with working ...Marija Živković, Aleksandar Mijatović, Dejan Ivezić, Boban Pavlović.
