  • 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: ...

  • Indexing of textual databases based on lexical resources: A case study for Serbian

    Ranka Stanković, Cvetana Krstev, Ivan Obradović, Olivera Kitanović (2015)
    In this paper we describe an approach to improvement of information retrieval results for large textual databases by pre-indexing documents using bag-of-words and Named Entity Recognition. The approach was applied on a database of geological projects financed by the Republic of Serbia in the last half century. Each document within this database is described by metadata, consisting of several fields such as title, domain, keywords, abstract, geographical location and the like. A bag of words was produced from these ...

  • Primena digitalne fotogrametrije u rudniku Rudnik

    Nikola Mirković, Luka Crnogorac, Katarina Urošević (2023)
    Digitalna fotogrametrija, lasersko skeniranje i virtuelizacija sve više pronalaze aktivne uloge u rudarstvu, prvenstveno zbog svoje široke mogućnosti primene. Laserskim skeniranjem i fotogrametrijom snimaju se i kreiraju 3D modeli otkopa, jamskih hodnika, površinskih kopova, površinskih objekata (zgrada, spomenika, predmeta), a vrši se skeniranje celih rudnika koji se rekonstruišu u 3D digitalne modele.

  • Poređenje rezultata interferometrijske analize za zemljotrese na istočnom anatolijskom rasedu od 2020. i 2023. godine

    Dragan Živković (2024)
    Ovaj rad se bavi analizom površinskih deformacija izazvanih zemljotresima u Turskoj iz 2020. i 2023. godine korišćenjem diferencijalne satelitske radarske interferometrije (DInSAR tehnike). Cilj istraživanja bio je da se kvantifikuju i uporede deformacije terena izazvane ovim seizmičkim događajima i da se razumeju mehanizmi koji stoje iza oslobađanja seizmičke energije u regionu. Analizom DInSAR snimaka, identifikovane su različite deformacije duž rasednih zona za svaki zemljotres. Dok je zemljotres iz 2020. godine (M 6,7) izazvao lokalizovane deformacije duž Istočno anatolijskog raseda, zemljotres ...

  • Model inteligentnog sistema adaptivnog upravljanja procesom prerade rude

    Ivana M. Jovanović (2016-01-13)
    U oblasti procesa prerade rude, flotacijska koncentracija predstavlja jednu od najznačajnijih i najčešće primenjivanih metoda separacije korisnih od nekorisnih minerala. Samim tim, veoma je važno osigurati uspešan rad flotacijskog postrojenja kroz dostizanje zadovoljavajućih tehno-ekonomskih pokazatelja. Cilj upravljanja procesom flotacijske koncentracije je upravo optimizacija kvaliteta i iskorišćenja korisne komponente u koncentratu uz maksimizaciju profita. Shodno tome, istraživanja na polju modelovanja i upravljanja ovim procesom zauzimaju značajno mesto u praksi kontolnog inženjenringa.Teorijska istraživanja u okviru doktorske disertacije obuhvatila su analizu položaja ...

  • Projection of SO2 emissions in coal power plants in Serbia

    Aleksandar Madžarević, Predrag Jovančić, Stevan Đenadić, Filip Miletić, Miodrag Ristović, Miroslav Crnogorac (2023)
    The production of electricity in the countries of South-Eastern Europe (SEE) was mainly related to the use of coal, predominantly lignite. The total installed capacity of thermal power plants using coal in these seven countries is 17.813 MW, distributed in 31 thermoblocks. The mentioned plants are the dominant pollutant emitters in all observed countries. Data on the largest emitters in the countries of the European Union and a comparison with SEE countries were collected. The calculation of emissions of ...

  • Karst aquifer impact on the formation of surface runoff: case study of the Resava River catchment, Serbia

    Marina Mitrašinović, Vesna Ristić Vakanjac, Veljko Marinović, Saša Milanović, Ljiljana Vasić, Dušan Polomčić (2022)
    The paper compares the flow regimes of the Resava River at the gauging stations of the Manasija Monastery (upper course) and the town of Svilajnac (lower course). The hydrological analysis encompasses a multiyear period of monitoring (1982–2020). The water budget and baseflow index are assessed for the catchment areas monitored by the Svilajnac station (683 km2) and the Manasija Monastery station (358k m2), considering the overall monitoring period and characteristic years. The results indicate that the specific runoff in ...
