  • Sitni, ali bitni: uloga sitnih sisara, herpetofaune i mekušaca u rekonstrukciji pleistocenskih paleosredina

    Katarina Bogićević, Draženko Nenadić, Dragana Đurić, Mihajlo Jovanović, Aleksandra Savković (2023)
    Fosilni ostaci životinja i biljaka imaju važnu ulogu u rekonstrukciji pleistocenskih paleosredina. U ovom radu opisan je značaj tri grupe životinja: sitnih sisara, herpetofaune I mekušaca. Mada je za rekonstrukciju važan sastav čitave asocijacije, nalasci pojedinih vrsta mogu biti dovoljno indikativni da otkriju tip staništa ili klimatske uslove. Posebnu teškoću pri rekonstrukciji paleosredina u Srbiji predstavlja činjenica da klimatske promene na Balkanskom poluostrvu nisu bile tako oštre kao u srednjoj i zapadnoj Evropi, pa ne postoji drastična razlika u ...

A particular difficulty in reconstructing palaecoenvironments in Serbia is the fact that climate changes on the Balkan Peninsula were not as sharp as in Central and Western Europe, so there is no drastic difference in composition, on the basis of which we would easily ...

  • Fault type assessment based on vertical gravity gradient anomalies – advantages and limitations

    Ivana Vasiljević, Snežana Ignjatović, Branislav Sretković (2024)
    The type of dip-slip faults can be assessed based on the analysis of vertical gravity gradients. Theoretically, just a simple comparation of the gradient extreme values can give us an answer whether the fault is normal or reverse (thrust). Practical application of this method is far more complicated and the results depend on a number of parameters, such as a complexity of geological setting, the quality of gravity data, dip angle and displacement of the fault, density contrast, etc. ...

  • Available technological procedures for capturing CO2 in the industrial and power generation sectors

    Lola Tomić, Vesna Karović Maričić, Dušan Danilović, Branko Leković, Miroslav Crnogorac (2021)
    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 ...

  • Non-Detonating Chemical Mixture for Non-Invasive Methods of Rock Breaking

    Lazar Kričak, Milanka Negovanović, Nikola Simić, Stefan Milanović (2024)
    Within the Innovation developed several different non-detonating chemical mixtures for non-invasive methods of rock breaking. Laboratory and polygon tests gave the satisfactory results and knowledge enough to start the practical experiments in the field. The basis of this innovation is a theoretical assumption that certain chemical mixtures release a large quantity of gases during combustion. If these gases are found in the enclosed space a growing pressure on the walls of the chamber in which combustion takes place will ...

  • 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 ...

  • 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 ...
