Gordana Gajica, Aleksandra Šajnovic, Jan Schwarzbauer, Aleksandar Kostić, Branimir Jovančićević, Ksenija Stojanović (2021)The molecular and isotopic composition of biomarkers in initial bitumen isolated from raw immature oil shale samples from the Lower Miocene Aleksinac Basin (Serbia) and liquid products (LPs) obtained by pyrolysis in open (OS) and closed systems (CS) are studied. The influence of pyrolysis type and variations of kerogen type on biomarkers composition and their isotopic signatures in LPs is determined. The molecular composition of the LPs from the OS pyrolysis is very similar to those in initial bitumen, independently ...... experiments were performed in open (OS, Pyrolyser, Model MTF 10/15/130 Carbolite, UK) and closed (CS, autoclave) systems at a temperature of 400 °C for 4 h.

Available technological procedures for capturing CO2 in the industrial and power generation sectors
Climate change is a major environmental issue caused by anthropogenic emissions of greenhouse gases. Capturing CO2 and storing it in suitable geological formations is one of the main technological solutions that can provide mitigation of CO2 emission into the atmosphere. Capturing CO2 represents the first phase in process of carbon capture and storage, and includes the application of various technologies for the separation of CO2 produced in the energy and industrial sectors. There are four main systems for capturing ...... . 27. Hinkov, I.; Lamari, F.D.; Langlois, P.; Dicko, M.; Chilev, C.; & Pentchev, I. CARBON DIOXIDE CAPTURE BY ADSORPTION (REVIEW).

Fuzzy optimization in hydrodynamic analysis of groundwater control systems: Case study of the pumping station “Bezdan 1”, Serbia
Dragoljub Bajić, Dušan Polomčić (2014)A groundwater control system was designed to lower the water table and allow the pumping sta-tion “Bezdan 1” to be built. Based on a hydrodynamic analysis that suggested three alternative solutions, mul-ticriteria optimization was applied to select the best alternative. The fuzzy analytic hierarchy process methodwas used, based on triangular fuzzy numbers. An assessment of the various factors that influenced the selec-tion of the best alternative, as well as fuzzy optimization calculations, yielded the “weights” of the alternativesand the ...groundwater lowering, groundwater management scenario, fuzzy analytic hierarchy process,expert knowledge, triangular fuzzy numbers, linguistic variables... then V(M1 ≥ M2) =1.

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.

Отварање и припрема лежишта за примену коморно-стубних метода откопавања
Никола Станишић (2024)Циљ мастер рада је да кроз теоријски преглед и практични пример, прикаже процес отварања и припреме лежишта за примену коморно-стубне методе окопавања. Предмет рада је мало лежиште олово-цинкане руде, а од варијација коморно-стубних метода откопавања, изабрана је коморно-стубна метода етажног откопавања са откопавањем одoздо на доле. Рад се бави темама одабира и описа начина отварања и припреме лежишта, методама откопавања, технологијом израде просторија и откопавања лежишта, организацијом рада и проценом трошкова и економичности експлоатације.... pyOHuka, Pynapcko-reo:momiku (Qpaky1reT, Beorpajn.
