The interaction of organoselenium trans-palladium(II) complexes toward small-biomolecules and CT-DNA
Serija organoselenijum trans-paladijum(II) kompleksa 1 (bis(2-(fenilselanilmetil)oksolan)dihloropaladijum(II)), 2 (bis(2-(fenilselanilmetil)oksan)dihloropaladijum(II)) i 3 (bis(2) ,2-dimetil-3-(fenilselanil)oksan)dihloropaladijum(II)) su korišćeni za ispitivanje reaktivnosti ovog specifičnog tipa kompleksa prema različitim bio-molekulima. Ovaj sistem je od posebnog interesa jer se jako malo zna o supstitucionim reakcijam organoselenijum paladijum(II) kompleksa sa trans konfiguracijom. Zamena koordinovanog hlorida sa serijom malih bio-molekula (l-Met, l-His, l-Cis, GSH i 5′-GMP) proučavana je pod uslovima pseudo-prvog reda kao funkcija koncentracije nukleofila i temperature korišćenjem tehnika zaustavljenog toka.

Rock slope stability analysis under Hoek–Brown failure criterion with different flow rules
The stability analysis of homogeneous rock slope following the Hoek–Brown failure criterion under the hypothesis of different flow rules is performed based on limit equilibrium and finite element methods. The applied failure criterion is the generalized Hoek–Brown that can be introduced as a shear/normal function in analysis applying different flow rules. The results are compared with those obtained by the application of equivalent shear strength parameters of the Mohr–Coulomb criterion, considering that this is still the most widely used ...Kružna klizna površ, Huk-Braunov kriterijum loma, Kriterijum popuštanja, Smičuća/normalna funkcija, Nivo napona, Verovatnoća i parametarska analizaSvetlana Melentijević, Zoran Berisavljević, Dušan Berisavljević, Claudio Olalla Marañón .

Palinomorfe sa lokaliteta Gostuška reka (Stara planina)
Ivan Rutović (2024)U radu su prikazani rezultati palinološkog istraživanja permsko-trijaskih sedimenata sa lokaliteta Gostuška reka. Palinološki kompleksi su detaljno analizirani, što je omogućilo morfološku, taksonomsku i paleoekološku identifikaciju palinomorfi. Istraživanje je pokazalo prisustvo velikog broja spora i polena golosemenica, dok je polen skrivenosemenica zastupljen u manjem procentu. Na osnovu paleoekoloških analiza, zaključeno je da je tokom formiranja sedimenata na lokalitetu vladala aridna klima, sa povremenim vlažnim fazama koje su omogućavale razvoj močvarne vegetacije.... „Paleozoik i Mezozoik".

Surface functional groups and degree of carbonization of selected chars from different processes and feedstock
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.

Geotechnical Conditions for Construction of Savski Trg Metro Station as a Part of the Belgrade Metro Line One
In order to solve serious traffic congestion in Belgrade, a number of studies regarding the Belgrade Metro construction have been carried out since 1973. However, only in 2019, the routes of the future metro lines 1 and 2 were de-fined as a part of the General Metro Construction Project. The lines are de-signed to intersect at the location of Sava Square, where an interchange met-ro station will be built. It represents a complex geotechnical structure consist-ing of three different ...Nemanja Stanic, Dragoslav Rakic, Josip Isek, Slavoljub Simic.

Definisanje strukturnih odnosa primenom postupka horizontalni gradijent
Različiti postupci matematičkih transformacija se mogu primeniti na gravimetrijskim i magne tometrijskim podacima, kako bi se na istražnom terenu definisali strukturno-tektonski odnosi. U radu su prikazani rezultati dobijeni korišćenjem postupka horizontalni gradijent i ukupni horizontalni gradijent na gravimetrisjkim podacima. Navedeni postupci su pomogli da se detektuju kontakti sa velikim padnim uglom (vertikalni ili subvertikalni kontakti), koji se mogu interpretirati kao rasedi.

Дефинисање циркулације карстних вода ,,Врело Кавак" у циљу одрживог управљања водним ресурсима
Милена Пућо (2024)У југоисточном делу Србије, североисточно од града Пирота формирана је богата карстна издан у оквиру јурских и доњокредних кречњака. Врело Кавак, које дренира ову издан учествује у водоснабдевању града Пирота.Дефинисање циркулације и специфичних услова дренирања ове карстне издани вршено је хидрохемијским и изотопским методама.
