Mirjana V. Banković (2018-07-13)Profitabilna eksploatacija sve složenijih ležišta je težak zadatak koji zavisi odtemeljnog procesa analize, planiranja i projektovanja rudnika. Izvodljiv strateškiplan mora da zadovoljava društvena, regulatorna, tehnološka, geometrijska iekonomska ograničenja.

Synthesis, magnetic, thermal and structural properties of Co(II), Ni(II) and Cu(II) complexes containing isophthalato ligands
A series of novel ternary Co(II), Ni(II) and Cu(II) complexes containing 2,20-dipyridylamine (dipya), 2,20-bipyridine (bipy), and 1,10-phenanthroline (phen), as aromatic diamine ligands, and dianion of isophthalic acid (ipht) have been prepared by ligand exchange reactions from diluted H2O/EtOH solutions. The complexes were characterized by elemental analysis, IR spectroscopy, magnetic susceptibility measurements and TG and DSC analysis. Three complexes, Cu(dipya)(ipht)H2O (1), Co(dipya)(ipht)2H2O (2) and Cu(ipht)(phen)2H2O (5) are polymeric with bis-monodentate ipht, while the other two complexes M(bipy)(ipht)4H2O, M@Co(II) (3) and ...комплекси прелазних метала, карбоксилатни лиганди, N-лиганди, кристална структура, магнетна својстваJelena Rogan, Dejan Poleti, Ljiljana Karanović, Zvonko Jagličić.

Smanjenje sleganja plitkih temelja primenom mikrošipova
Slobodan Ćorić, Dragoslav Rakić (2021)Mikrošipovi su šipovi malog prečnika koji se grade tako što se u tlu specijalni postupkom formira bušotina koja se zatim armira i injektira. Njihov prečnik je najčešće 150 – 300 mm, a dužina može da bude i više desetina metara. Mikrošipovi mogu da se grade u svim vrstama tla i mogu da budu vertikalni i kosi. Oni se, stoga, koriste kao zamena za konvencionalne šipove i ankere. Primena mikrošipova u fundiranju predstavlja jedan savremeni način izgradnje i sanacije temelja/objekata. ...Slobodan Ćorić, Dragoslav Rakić.

Curcumin nanonization using an alternative small-scale production unit: selection of proper stabilizer applying basic physicochemical consideration and biological activity assessment of nanocrystals
Ines Nikolić, Jelena Antić-Stanković, Dragana Božić, Danijela Ranđelović, Bojan Marković, Dominique Jasmin Lunter, Aleksandar Kremenović, Miroslav Savić, Snežana Savić (2020)As the number of poorly soluble drugs is increasing, nanocrystals have become very interesting due to wide range of application possibilities. Curcumin was used as a model active ingredient in this work. Even though it has many proven positive effects, due to its physicochemical issues, its possibilities have not been fully exploited. The goal of this work was to select optimal conditions for a top-down method for curcumin nanosuspension production, and to perform their comprehensive characterization applying complementary methodologies: ...Ines Nikolić, Jelena Antić-Stanković, Dragana Božić, Danijela Ranđelović, Bojan Marković, Dominique Jasmin Lunter, Aleksandar Kremenović, Miroslav Savić, Snežana Savić.

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.

Овај рад истражује различите методе снимања терена, укључујући ласерско скенирање и фотограметријско снимање терена. Такође, детаљно се анализира употреба беспилотне летелице модела Aibot X6 V2 за месечно снимање радова на површинском копу ,,Дрмно“. Прикупљени подаци су обрађени помоћу ......

Merenje pritiska u bušotinskom cevovodu
Ratko Matija (2024)Merenje pritiska ima veliki značaj u naftovodima i gasovodima. U ovom završnom radu analizirane su različite metode merenja pritiska , kao što su merenje pritiska manometrima sa tečnostima, kapacitivnim manometrima, električnim manometrima nekim drugim. Objašnjena je kalibracija senzora pritiska koja u velikoj meri utiče na tačnost merenja. Navedeni su i objašnjeni elementi cevovoda i u vezi s tim pad pritiska, čije je merenje tema ovog završnog rada.... gasovod [bar] · Pj»- ppritisak na izlazu iz gasovoda [bar] 4- koeficijent trenja O – protok fluida [m*/h] ; [kg/h] // – gustina fluida [kg/m"] L- dužina cevovoda [m] D- unutrašnji prečnik cevovoda [m] Za cevovode visokog i srednjeg pritiska: 2, – P,?={1.7108 · 10 · Z-2-pf-Q? ·L) / D* gde su: ...

Paskal se definiše kao: [Pa] = [N] / [m]' = [kg]/[m] * [s]* .Paskal je Jedinica koja nije pogodna za korišćenje u svakodnevnom životu, pa se zato koriste veće Jedinice: -– kilopaskal IkPa = 1 ...Ratko Matija.
