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, ...... toward monofunctional ri a neeeat [Ru(terpy)(bipy)Cl]* complexes decrease in order: Tiourea>DMSO>His > 5'-GMP. * As can be seen from Fig. 3, the dominating hydrolytic complex at lower pH values is (2, -1), with maximum a concentration at pH = 7. re P eee " : ie a ‘f acts Wea i a B.

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 ...Dejan Ivezić, Miodrag Gluščević, Marija Živković.

A fuzzy-based decision support model for effectiveness evaluation - a case study of examination of bulldozers
Effectiveness evaluation is one of the basic components of engineering asset management and maintenance engineering in general. Effectiveness is an overall concept representing a measurement of quality of service level for the analyzed engineering system. This concept contains a series of partial indicators relating to time in operation and time for maintenance activities, as well as functional properties of the system. This article describes the analysis and structuring of partial indicators, as well as the development of a model ...... indicators into one – effectiveness (E). The fuzzy proposition is a procedure for representing a statement that includes linguistic variables based on available information about the considered engineering system (Klir & Yan, 1995). A definition of structure and interdependence of linguistic variables ...

Modeliranje disperzije dimnih gasova iz termoelektrane ,, Nikola Tesla”
Milica Kostić (2024)Termoelektrane na ugalj, iako značajan izvor električne energije, predstavljaju veliki izazov zbog zagađenja koje uzrokuju. Glavni uzrok zagađenja je neumerena ljudska potreba za energijom i resursima, što dovodi do emisije različitih zagađivača u atmosferu, uključujući okside ugljenika, sumpora, azota, kao i lebdeće čestice i toksine. Ove emisije imaju negativan uticaj na kvalitet vazduha, zdravlje ljudi i životnu sredinu. Procena uticaja termoelektrana na ugalj na životnu sredinu je zakonska obaveza i ključna za smanjenje tih negativnih efekata.

Mariја Bošković (2024)Rad ukazuje na savremene metode rešavanja problema industrijskog otpada, sa posebnim fokusom na pećnu prašinu koja nastaje tokom metalurških procesa, poput proizvodnje čelika u elektrolučnim pećima. U radu se detaljno razmatra hemijski sastav pećne prašine, koja sadrži teške metale poput cinka, olova i kadmijuma, i naglašavaju ekološki izazovi koje predstavlja njeno zbrinjavanje. Takođe, analiziraju se metode tretmana i valorizacije pećne prašine, uključujući pirometalurške i hidrometalurške procese, pri čemu je poseban akcenat stavljen na reciklažu cinka iz pećne prašine.

U strukturama arsenata i fosfata, AsO4- i PO4-tetraedrinajčešće se vezuju sa tetraedarski ili oktaedarski koordinisanim katjonima prelaznihmetala formirajući otvorene strukture (slojeve ili 3D mreže) sa širokim opsegomrazličitih topologija. U šupljinama ili porama u obliku povezanih ili nepovezanihkanala, tunela, kaveza i međuslojnog prostora mogu se ugraditi različiti vanmrežni joni(obično ...Sabina Z. Kovač.
