Geološke karakteristike neogenih sedimenta na prostoru šire okoline Ledinaca
Aleksandar Tričković (2024)Sagledavanje evolucije neogenih sedimenata na prostoru šire okoline sela Ledinci omogućeno je primenom različitih stratigrafskih metoda na površinskim i potpovršinskim podacima. Za izradu rada korišćene su sedimentološke, biostratigrafske, geofizičke i riftno sekvencione metode, koje su primenjene na površinskim izdancima i bušotinama. Primenom principa riftne sekvencione stratigrafije na podacima dobijenim geofizičkim karotažnim merenjima dobijeni su podaci o vremenu ekstenzije u Panonskom basenu. Pored toga ovi podaci zajedno sa sedimentološkim i stratigrafskim metodama omogućili su izdvajanje depozicionih sredina tokom neogena.

A Knowledge-Based Approach to Mine Ventilation Planning in Yugoslav Mining Practice
Ventilation system analysis is a complex process based on the calculation and analysis of numerous parameters. These problems can be successfully solved by the SimVent numerical package, but a full understanding and use of the obtained results require the involvement of an experienced specialist in the ventilation field. The solution was found in the creation of a hybrid system INVENTS, whose knowledge base represents a formalization of the expert knowledge in the mine ventilation field. In this paper, we ...Nikola Lilić, Ivan Obradović, Ranka Stanković.

Одређивање оптималних параметара цевовода за двофазни проток
Николина Ћурчић (2024)Eфикасно управљање протоком флуида је кључно за оптимизацију перформанси система и обезбеђивање оперативне сигурности. Двофазни ток, који подразумева истовремено присуство течне и гасне фазе унутар цевовода и измењивача топлоте, представља један од најсложенијих аспеката динамике флуида. Овај феномен намеће јединствене изазове који захтевају дубоко разумевање и прецизно планирање. Ефикасно управљање двофазним током није само кључно за одржавање ефикасности система, већ је и неопходно за спречавање потенцијалних проблема као што су повећана ерозија, неочекиване флуктуације притиска и ризици по безбедност.

Hydrographic and hydrological characterization of the Vodenička and Rosomačka rivers
Vesna Ristić Vakanjac, Marina Čokorilo Ilić, Dušan Polomčić, Dragoljub Bajić, Jelena Ratković (2017)The Visočica River rises in Bulgaria, on the Berovo Mountain. Its course in Bulgaria is 16.7 km long. It enters Serbia near the village of Donji Krivodol. Up to the village of Pakleštica, or the beginning of Lake Zavoj, its right-bank tributaries are the Krivodolštica, the Vodenička, the Rosomačka and the Dojkinačka. There are no left-bank tributaries. Among the tributaries, water levels and discharges are gauged only on the Dojkinačka River. The Vodenička had also been gauged but only ...Vesna Ristić Vakanjac, Marina Čokorilo Ilić, Dušan Polomčić, Dragoljub Bajić, Jelena Ratković.

Аnaliza mogućnosti povećanja nagiba završne kosine površinskog kopa “Podbraćan”
Vladimir Čebašek, Veljko Rupar (2018)Eksploatacijom boksita iz ležišta "Podbraćan" formiran je površinski kop sa maksimalnom visinom zavšne kosine od 280 m. Redovnom kontrolom stabilnosti trenutnog stanja kosina površinskog kopa utvrđeno je da faktor sigurnosti iznosi Fs = 1.71 – 1.85, a što je ukazalo da postoji mogućnost povećanja nagiba kosine.

Multiphase evolution of fluids in the Rudnik hydrothermal-skarn deposit (Serbia): new constraints from study of quartz-hosted fluid inclusions
This study presents and discusses first detailed petrographic, microthermometric and Raman spectroscopic data from quartzhosted fluid inclusions at Rudnik Zn-Pb-Cu-Ag skarn deposit (Serbia) and combines them with the information on skarnand ore paragenesis. Three periods in the metamorphic-hydrothermal history of the deposit are recognized: 1) the pre-ore prograde skarn period when garnet-clinopyroxene skarns formed, 2) the syn-ore period that encompasses a retrograde stage marked by epidote and zoisite and a quartz-sulfide stage characterized by quartz, pyrrhotite, sphalerite, galena and ...skarnovska ležišta, rudnik, fludine inkluzije, srpska kenozojska magmatska provincija, Zapadno Tetisjki metalogenetski pojas... metamorphic rocks Clay-carbonate unit [Z Sandy-Carbonate unit [__] carbonate unit | siciclastic unit __- Fault 77 Nappe al ti tu de (m ) F-i ii > [ ouanz-latite intrusive shallow facie: Quartz-latite extrusive deeper facies [__] Upper Cretaceous sedimentary series [E Lower Cretaceous ...

Modeliranje disperzije dimnih gasova iz termoelektrane Kostolac B
Bojan Živanović (2024)Bez hrane se može preživeti nedelju dana, bez vode svega nekoliko dana, međutim, bez vazduha se može preživeti najmanje, nekoliko minuta. Pitanje je kakav uticaj na zdravlje čoveka i okoline ima vazduh koji je lošeg kvaliteta, a kojem je skoro celokupno stanovništvo planete izloženo? Ovaj rad se bavi problematikom modeliranja disperzije dimnih gasova iz novog bloka B3 TE ,,Kostolac’’ B.

Ionothermal synthesis and crystal structure of a new organic–inorganic hybrid compound:catena-poly[bis(1-ethyl-3-methylimidazolium) [hepta-μ-bromido-pentacuprate(I)]]
A new organic-inorganic hybrid compound, catena-poly[bis(1-ethyl-3-methylimidazolium) [μ5-bromido-tri-μ3-bromido-tri-μ2-bromido-pentacuprate(I)]], {(C6H11N2)2[Cu5Br7]}n, has been obtained under ionothermal conditions from a reaction mixture containing Ba(OH)2•8H O, Cu(OH)2•2H2O, As2O5 , 1-ethyl-3-methylimidazolium bromide and distilled water. The crystal structure consists of complex [Cu5Br7]2- anions arranged in sinusoidal {[Cu5Br7]2-}n chains running along the a axis, which are surrounded by 1-ethyl-3-methylimidazolium cations.

Production of electricity from coal-fired power plants and accompanying CO2 emissions: comparison of EU-27 and US
Even in the third decade of the 21st century, large power plants are still responsible for more than half of the electricity production in Europe and US. They predominantly use fossil fuels in their work, which results in the emission of pollutants into the air, soil and water. In addition to the production of electric energy, fossil fuels, including coal, are used for industrial purposes. Although the use of coal, especially in the countries of the European Union, is ......

Analysis of the exhaust emissions inventory from auxiliary mining machines
Stevan Đenadić, Aleksandar Mirković, Jovana Mitrović, Filip Miletić, Predrag Jovančić, Dragan Ignjatović (2023)Open-pit coal mines are equipped with a large number of mining machines and vehicles with diesel engines. Due to common daily operation of these machines and vehicles large amounts of exhaust gases which contain numerous pollutants are emitted into the atmosphere. The demand to reduce air pollution induced the activities in developed countries to map and calculate all gases emitted by industries to formulate and select adequate preventive activities. In collaboration with machine manufacturers, emission standards for off-road machines ...Stevan Đenadić, Aleksandar Mirković, Jovana Mitrović, Filip Miletić, Predrag Jovančić, Dragan Ignjatović.
