The challenges for Z-generation geologists
Dejan Radivojević (2022)Nastupajuća generacija geologa suočava se sa nekim problemima koji su poznati i njihovim prethodnicima, ali takođe i sa do sada novim i nepoznatim izazovima. Činjenica da mnogi geologiju povezuju sa „prljavim“ industrijama u kojima će biti sve manje prilika za zaposlenje u vreme kada se teži čistoj vodi, zemljištu i vazduhu kao i to da je smatraju zastarelom u sadašnje vreme brzog tehnološkog razvoja dovela je do velikog pada interesovanja za studije geologije svuda u svetu.

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 ...... in database technology provide nowadays for management of large quantities of heterogeneous data.

Primena aeromagnetskih i gravimetrijskih podataka pri izrad geofizičkog-geološkog modela dela Timočkog magmatskog kompleksa
Snežana Ignjatović (2023)Geofizičke metode istraživanja imaju veoma veliki značaj pri definisanju Zemljine potpovršine, pošto podaci dobijeni geofizičkim merenjima mogu da se koriste za izradu geofizičko – geološkog modela za prostor koji se istažuje. Na primeru sevrnog dela Timočkog magmatskog kompleksa (TMK) u radu je prikazano kako se primenom geofizičkih (aeromagnetskih i gravimetrijskih) i geoloških podataka može napraviti model istažnog terena u cilju definisanja potpovršine.

Wells calculation for the protection of opencast mine Radljevo North from groundwater
Za projektovanje kvalitetnog sistema zaštite jednog površinskog kopa od podzemnih voda bitno je da ulazni podaci budu verodostojni, kako bi se na osnovu njih izvršili potrebni proračuni objekata odvodnjavanja podzemnih voda. Proračunima za površinski kop Radljevo Sever je omogućeno da se dobije potreban broj bunara kako bi oni pravilno funkcionisali i obezbedili potrebno obaranje podzenih voda.Dušan Polomčić, Vladimir Petković, Miloš Jeremić.

Possibilities of retro-digitalized German-Serbian Mining Dictionary
U radu će biti prikazan opis procesa retrodigitalizacije dvojezičnog Nemačko-srpskog rudarskog rečnika iz 1923. godine čiji je autor rudarski inženjer Dragutin Stepanović (Степановић, 1923). Ovaj rečnik je zasnovan na skoro 4 000 leksičkih zapisa koji su prevodilački ekvivalenti ili uputnice. Umesto predgovora autor daje uvid u svoje pismo upućeno “Ministru šuma i rudnika” u kome piše o nameri da zabeleži reči koje se koriste u narodu kako bi izbegao upotrebu nemačkih reči. Iako broj odrednica nije toliko veliki, rečnik ...Biljana Lazić, Olivera Kitanović, Ivan Obradović.

Late and post-collisional tectonic evolution of the Adria-Europe suture in the Vardar Zone
The Vardar Zone is a product of the Triassic-Jurassic opening of the Neotethys, Jurassic obduction, Late Cretaceous/Paleogene consumption of the oceanic crust and continental collision. During the last process, the Eastern Vardar Zone was thrust over the Central and eventually both onto the Western Vardar Zone.

The influence of Al<sup>3+</sup>ion on porcine pepsin activity<i>in vitro</i>
The in vitro effect of Al3þ ions in the concentration range 1.7·1026M–8.7·1023M on pepsin activity at pH 2, via kinetic parameters and its electrophoretic mobility was evaluated. Kinetic study demonstrated the existence of an activation effect of Al3þ at pH 2 on pepsin molecule. Kinetic analysis with respect to concentrations of haemoglobin showed that Al3þ ions increase the maximal velocity (Vmax) and kcat values rather than apparent affinity for substrate (KS) implying the non-competitive nature of activation which indicated ...... spectral and aluminium binding assays data (experimental data not shown) the fraction of bound aluminium to pepsin v and dissociation constant for pepsin-aluminium complex K a, were found to be 0.96 + 0.09 and 8.39 + 0.76LM respectively [31].
