Clockwise vertical-axis rotation in the West Vardar zone of Serbia: Tectonic implications
The Vardar-Tethyan mega-suture between the Eurasian and Adria (Gondwana) margins comprises remnants of oceanic lithosphere of Neotethys and distal parts of the adjacent continental margins including unconformable Late Cretaceous sedimentary cover and Cenozoic igneous rocks of post-obduction age. This study provides kinematic constraints for displacements and rotations affecting the Serbian part of the West Vardar and Jadar-Kopaonik units after the closure of the Neotethyan (= Sava) Ocean. The targets of the paleomagnetic research were Late Cretaceous sediments representing an ...... 2 2 9 4 .4 5 .6 V ar ia b le U p p e r C a m p a n ia n 7 T o li ć q u ar ry 4 0 1 5 – 0 2 2 4 4 � 1 3 0 1 4 00 2 0 � 2 8 0 4 3 00 L im es to n e R ed 8 /8 3 5 9 .9 * 5 8 .0 * 2 7 1 3 .4 3 5 0 .1 4 6 .2 2 7 1 3 .4 3 2 2 /1 4 U p p e r C a m p a n ia n 8 L ip o v ic a q u ar ry ...

Debris-flow Susceptibility Assessment in Flow-R: Ribnica River Case Study
Debris flows are among the most dangerous erosional geohazards due to the fast rate of movement and long runout zones. Even though the initiation can be triggered in mountainous areas, inhabited and with steep slopes, their propagation and deposition can endanger not only buildings and infrastructure in the urbanized areas, but also threaten human lives. As these initiation areas usually represent unattainable terrains with rapid vegetation cover development, field observations and aerial photo analysis become high-demanding tasks. Consequently, medium-to-regional ...Ksenija Micić, Miloš Marjanović, Biljana Abolmasov .

Uticaj površinske obrade kamena na promenu primarne poroznosti
Ana Radivojević (2024)Površinska obrada kamena je izuzetno bitna kod stena koje se koriste u izgradnji svih vrsta objekata. Površinskom obradom se direktno utiče, ne samo na estetska svojstva kamena nego i na njegove fizičko-mehaničke karakteristike. Cilj ovog završnog rada je analiza uticaja poliranja i rezanja kao tehnoloških procesa obrade na poroznost odabranih vrsta arhitektonsko-građevinskog kamena. Ispitivane stene su gabro „Nero Assoluto“, granit sa površinskog kopa „Ploče“, granit African Red, krečnjak sa lokaliteta „Skržut“ i krečnjak poznat pod nazivom „Sirogojno crveni“.... vode u odnosu na rezane.

Improving Document Retrieval in Large Domain Specific Textual Databases Using Lexical Resources
Large collections of textual documents represent an example of big data that requires the solution of three basic problems: the representation of documents, the representation of information needs and the matching of the two representations. This paper outlines the introduction of document indexing as a possible solution to document representation. Documents within a large textual database developed for geological projects in the Republic of Serbia for many years were indexed using methods developed within digital humanities: bag-of-words and named ...... or a geological event like landslide or earthquake. For evaluation standard measures were used, namely precision P = tp/(tp + fp), recall R = tp/(tp + fn), and F1-measure F = 2 · P · R/(P + R), where tp – true positive is the number of relevant documents retrieved, fp – false positive is the number ...

Tektonska evolucija ugljevičkog basena (Bosna i Hercegovina)
Slobodan Dragić (2024)U radu je prezentovana šira slika tektonske evolucije ugljevičkog basena, kao i Dinarida uopšte. Prikazani su litostratigrafski odnosi istraživanog područja, kao i kratak pregled tektonskih jedinica koje se nalaze u domenu basena. Najveća pažnja posvećena je kinematskoj analizi rasjednih struktura i interpretaciji podataka u svjetlu tektonske evolucije basena. Ugljevički basen zapunjen je oligocensko-miocenskim sedimentima, a njegovu osnovu grade paleozojsko-mezozojske formacije. Najstarije tvorevine na ovom području su permski sedimenti.
