  • Kvantitativne karakteristike eksploatacionog režima podzemnih voda na izvorištu "Jaroš" - Sombor

    Dušan Polomčić, Jelena Ratković, Vesna Ristić Vakanjac, Dejan Tadić, Bojan Hajdin (2024)
    Izvorište "Jaroš" formirano je na prostoru SOmbora. Podzemne vode koje se zahvataju na izvorištu sa ukupno 18 bunara koriste se za vodosnabdevanje grada Sombora, prigradskih i okolnih naselja. Podzemne vode se zahvataju iz zbijenog tipša izdani sa slobodnim nivoom kvartarne starosti. Hidrodinamički model režima podzemnih voda izrađen je u cilju analize eksploatacionog režima i bilansa podzemih voda na izvorištu "Jaroš". Primenom hidrodinamičkog modela zasnovanog na numeričkoj metodi konačnih razlika određen je bilans podzemnih voda za područje istraživanja predmetnog izvorišta, ...

  • Određivanje parametara smičuće čvrstoće tla primenom statističke metode

    Božidar Rudnjanin (2024)
    Određivanje parametara smičuće čvrstoće tla je od ključne važnosti u geotehničkom inženjerstvu jer utiče na stabilnost i nosivost raznih građevinskih konstrukcija. Ovaj master rad obrađuje temu primene deskriptivne statistike za analizu parametara smičuće čvrstoće tla,čime se obezbeđuje osnov za donošenje odluka o planiranju i izvođenju građevinskih projekata.U prvom delu rada, prikupljaju se relevantni podaci o smičućoj čvrstoći tla iz prethodnih laboratorijskih ispitivanja za trasu buduće brze saobraćajnice Novi Sad - Ruma.Ti podaci uključuju vrednosti smičuće čvrstoće i različite faktore ...

  • Using gravity data to define structural correlation affecting the formation of Neogene basins

    Snežana Ignjatović, Ivana Vasiljević, Branisav Sretković, Milanka Negovanović (2023)
    A gravity survey can help to define the structural correlation in the study area. The structures that have influenced the development of Neogene basins can be defined using gravity data. By applying mathematical transformations to gravity data, the geological structures (faults, nappes, etc.) that impacted the formation of Neogene basins can be defined. We have taken the part of the Dinarides as the test region. The paper presents the results obtained using the procedure residual, vertical gradient, and total ...

    Marija Ilić, Franz-Hubert Haegel, Aleksandar Lolić, Zoran Nedić, Tomislav Tosti, Ivana Sredović Ignjatović, Andreas Linden, Nicolai D. Jablonowski, Heinrich Hartmann (2022)
    The knowledge ofthe structural and chemical properties of biochars is decisive for their application as technical products. For this reason, methods for the characterization of biochars that are generally applicable and allow quality control are highly desired. Several methods that have shown potential in other studies were used to investigate two activated carbons and seven biochars from different processes and feedstock. The chars were chosen to cover a wide range of chemical composition and structural properties as a hardness ...

  • Freeze-dried nanocrystal dispersion of novel deuterated pyrazoloquinolinone ligand (DK-I-56-1): Process parameters and lyoprotectant selection through the stability study

    Jelena R. Mitrović, Maja Bjelošević Žiberna, Aleksandar Vukadinović, Daniel E. Knutson, Dishary Sharmin, Aleksandar Kremenović, Pegi Ahlin Grabnar, Odon Planinšek, Dominique Lunter, James M. Cook, Miroslav M. Savić, Snežana D. Savić (2023)
    Recently, nanocrystal dispersions have been considered as a promising formulation strategy to improve the bioavailability of the deuterated pyrazoloquinolinone ligand DK-I-56-1 (7‑methoxy-2-(4‑methoxy-d3-phenyl)-2,5-dihydro-3H-pyrazolo[4,3-c]quinolin-3-one). In the current study, the freeze-drying process (formulation and process parameters) was investigated to improve the storage stability of the previously developed formulation. Different combinations of lyoprotectant (sucrose or trehalose) and bulking agent (mannitol) were varied while formulations were freeze-dried under two conditions (primary drying at -10 or -45 °C). The obtained lyophilizates were characterized in terms ...

    The Borska Reka ore deposit is an experimental location where developed methodologies have been applied. It is the largest ore body within the Bor mining complex, which has been the subject of numerous studies and analyses for more than three decades. The paper focuses on the application of FAHP and the VIKOR method to address ranking of alternatives and select the optimal mining method by means of fuzzy multicriteria optimization.

  • Method validation and geochemical modelling of chromium speciation in natural waters

    Piotr Rusiniak, Katarzyna Wątor, Ewa Kmiecik, Vesna Ristić Vakanjac (2024)
    The study focuses on validating reference methods such as ICP-OES and ICP-MS for detecting ultratrace levels of chromium in groundwater, where concentrations are typically very low. Additionally, it verifies a hyphenated technique, IC-ICP-MS, for determining naturally occurring Cr(VI) in tested waters. The validation process involved various chromium analysis variants, including isotopes 52Cr and 53Cr in ICP-MS and IC-ICP-MS techniques, along with specific emission lines in the ICPOES technique. Statistical data processing revealed that the achieved limits of quantification for ...

    The Selanac debris flow is a very huge event triggered after extreme rainfall caused by Cyclone Tamara activity in the Republic of Serbia in May 2014. The Selanac case study was already modelling in different programs using Voellmy rheology assumptions like RAMMS software. In this paper research are focusing particularly on the process of debris flowing from initiation zone to main deposition area using Geoflow SPH two-phase model considering frictional rheology law. Main rheological parameters are back-calculated using also ...
