The Late Devonian contraction along the Precaspian Basin north margin: Transpressional range building in the intracratonic domain
Novak Novčić, Marinko Toljić (2023)The evolution of intraplate sedimentary basins located in the vicinity of an active convergent plate boundary is often controlled by the collisional dynamics of the adjacent orogen. The transfer of compression from the orogen to the platform's interior results in the formation of complex structural geometry and kinematics that often reactivate older crustal faults, focus far-field stresses and control the evolution of associated sedimentary basins. One place where this localisation can be optimally understood is the Precaspian Basin, situated ...Intrakratonske deformacije, transpresija, kosa kompresija, krustalni rasedi, intrakratonski transfer stresa, kontrakcioni blokoviNovak Novčić, Marinko Toljić.

The first record of nautiloids (Cenoceras intermedius) from the early Pliensbachian of Rgotina, (Getic nappe, eastern Serbia)
Cenoceras intermedius (J. Sowerby) is one of the most widespread species among the Early Jurassic nautiloid fauna and its geological range still controversial up to the present day. The specimen of Cenoceras intermedius from the sandy bioclastic limestones of Rgotina (Getic nappe of eastern Serbia), is a large half conch representing the phragmocone. Viewing our findings in light of previous results suggests the main morphological changes occurred during the ontogenetic evolution. The coiling starts with a round-square whorl section, ...Cephalopoda, Cenoceras intermedius, ontogenetic changes, geological range, northwestern Neo-Tethys, PliensbachianPaul Țibuleac, Barbara V.

Chalcopyrite Floatability in Flotation Plant of the Rudnik Mine
У раду је приказан део резултата обимних индустријских испитивања утицаја финоће млевења руде на резултате флотације минерала олова, бакра и цинка из руде рудника "Рудник". На основу резултата индустријских испитивања, констатовано је да се при једностепеном млевењу и двостепеном класирању комплексне Pb-Zn-Cu руде, појављује проблем тзв. диференцијалне мељивости. Наиме, галенит као мек минерал знатно брже се уситњава од осталих минерала у руди. Ово доводи до тога да минерал галенит прелази у ситне класе које споро флотају, а у ...Predrag Lazić, Đurica Nikšić, Rudolf Tomanec, Dušica Vučinić, Lidija Cvetićanin.

Recent advances made by reaction experiments on melting of heavily metasomatized hydrous mantle
Dejan Prelević, Michael W. Förster, Stephan Buhre, Fatma Gülmez, Tobias Grützner, Yu Wang, Stephen F. Foley (2024)Mantle-derived magmas are traditionally assumed to originate by melting of an upper mantle consisting of uniform spinel- or garnet peridotite dominated by olivine. However, extensive studies of mantle-derived basalts suggest that the mantle is more mineralogically heterogeneous, so that the genesis of even the most common magmas requires consideration of mixed source regions within the mantle involving pyroxenites and hydrous minerals. We refer to these with the group term metasomes. However, most experimental studies on mantle melting have assumed ...Dejan Prelević, Michael W.

Flotability of chalcopyrite from the Rudnik deposit
Директно селективно флотирање олова, бакра и цинка у флотацији рудника „Рудник” датира од 1984. године. Технолошка шема омогућава директно издвајање селективних концентрата у три циклуса. У првом циклусу се издваја минерал олова (галенит), док су минерал бакра (халкопирит) и минерал цинка (марматит) депримирани. У другом циклусу се оток концентрације минерала олова кондиционира и припрема за издвајање минерала бакра. Након кондиционирања, у овом циклусу се издваја минерал бакра. У трећем циклусу се оток концентрације минерала бакра кондиционира и припрема за ...Đurica Nikšić, Predrag Lazić, Milena Kostović.

An example of karst catchment delineation for prioritizing the protection of an intact natural area
Vesna Ristić Vakanjac, Zoran Stevanović, Aleksandra Maran Stevanović, Boris Vakanjac, Marina Čokorilo Ilić (2015)Проучавано је карстни извор Перућац као главни дрен подручја планине Таре у западној Србији у циљу процене његовог режима отицања, резерви воде и дефинисања његове сливне површине. Извор се налази у североисточној, унутрашњој зони класичног динарског крша, коју карактерише доминантно проширење висококарстификованих тријаских кречњака, слабо развијена хидрографска мрежа са много понора и густе шуме. Тара је један од пет националних паркова у Србији. Циљ рада је био да се идентификује заштитна зона високог приоритета у оквиру очуваног природног подручја ...Vesna Ristić Vakanjac, Zoran Stevanović, Aleksandra Maran Stevanović, Boris Vakanjac, Marina Čokorilo Ilić.

Automatic construction of a morphological dictionary of multi-word units
The development of a comprehensive morphological dictionary of multi-word units for Serbian is a very demanding task, due to the complexity of Serbian morphology. Manual production of such a dictionary proved to be extremely time-consuming. In this paper we present a procedure that automatically produces dictionary lemmas for a given list of multi-word units. To accomplish this task the procedure relies on data in e-dictionaries of Serbian simple words, which are already well developed. We also offer an evaluation ...electronic dictionary, Serbian, morphology, inflection, multiwordn units, noun phrases, query expansionCvetana Krstev, Ranka Stanković, Ivan Obradović, Duško Vitas, Miloš Utvić.

Model za optimizaciju graničnog saržaja metala u rudi u funkciji dugoročnog planiranja površinskih kopova
Daniel P. Kržanović (2016-06-14)Optimizacija graničnog sadržaja metala u rudi jedan je od osnovnih koraka u planiranju i dizajniranju površinskih kopova i ima za cilj postizanje maksimalne neto sadašnje vrednosti (NPV). Iz tog razloga, optimizacija graničnog sadržaja i danas je predmet mnogih istraživanja u rudarskoj nauci, sa ciljem rešavanja praktičnih problema u eksploataciji ležišta.Dugoročno planiranje eksploatacije na površinskim kopovima podrazumeva sagledavanje svih relevantih parametara i faktora (geologije rudnog ležišta, tehnologije proizvodnog procesa, kapaciteta otkopavanja i prerade, troškova, cena metala, iskorišćenja i dr) kako ...površinski kop, dugoročno planiranje, optimizacija graničnog sadržaja, maksimizacija neto sadašnje vrednosti (NPV).Daniel P.
