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. Мултидисциплинарни приступ истраживања резултирао је сазнањима да се ради о спорој циркулацији подземних вода, као и водама различите старости, што је од великог значаја за управљање природним ресурсом као што су подземне воде врела ...... koTnuMHe, Mehy kojua je M Bpeno KaBak.

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 expansion... lekar akušer obstetrician Both components inflect and agree in case and number nc nxnf kit ubica killer whale The gender of the second component changes in plural nc nxn3 kamen- temeljac foundation stone The separating hyphen can be omitted nc nxn2 Kongo Brazavil Congo- Brazzaville Neither of the ...Cvetana Krstev, Ranka Stanković, Ivan Obradović, Duško Vitas, Miloš Utvić.

Terminology Acquisition and Description Using Lexical Resources and Local Grammars
Acquisition of new terminology from specific domains and its adequate description within terminological dictionaries is a complex task, especially for languages that are morphologically complex such as Serbian. In this paper we present an approach to solving this task semi-automatically on basis of lexical resources and local grammars developed for Serbian. Special attention is given to automatic inflectional class prediction for simple adjectives and nouns and the use of syntactic graphs for extraction of Multi-Word Unit (MWU) candidates for ...... of inflectional classes. 1 Introduction In this paper we present a semi-automatic proce- dure for terminology acquisition in Serbian.

Availability as a dimension of energy security in the Republic of Serbia
Boban Pavlović, Dejan Ivezić (2016)There is a range of modern approaches and models in literature for the evaluation and determination of energy security, which are based on different parameters and indicators. For most of them, a common characteristic is emphasizing the avail ability of energy, as an important dimension for ensuring energy security. In this paper, concise overview of Serbian energy sectors is given and appropriate energy indicators are defined and determined. Selected indicators provide insight into the main components that characterize availability ...... RES in total final consumption (TFC) (RES2). The TPES is calculated as the sum of primary production and import, less to the sum of export, stock changes, bunkers, and statistical difference [9].

Crystallography and Surface Oxidation of Stoichiometric Arsenopyrite from Šumadija-Kopaonik Pb-Zn/Polymetallic Ore District (Serbia)
Ivana Jelić, Aleksandar Pačevski, Aleksandar Kremenović, Aleš Šoster, Andreja Šestan, Janez Zavašnik (2023)The behaviour and stability of arsenopyrite largely depend on its crystal structure, but studies of crystallography and structural defects are scarce. For clarification, we investigated a series of natural arsenopyrite crystals from the polymetallic Pb-Zn-(±Cu,Ag,Au,Sb,Bi,W) Šumadija-Kopaonik ore district (Serbia) by powder X-ray diffraction (XRPD). Among them, samples from the Drenjak gold mineralisation showed near-stoichiometric FeAsS composition and were further investigated by conventional and high-resolution transmission electron microscopy methods. TEM revealed abundant planar crystallographic defects and epitaxial surface oxide layer ...Inorganic Chemistry, Condensed Matter Physics,General Materials Science, General Chemical Engineering, crystal structure, FeAsS, oxidation, TEM, XRPD...

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 ...... 2011). The dacitoandesites were considered to be older than the granodiorite intrusions since the Kremići intrusion caused metamorphic/metasomatic changes in the surrounding dacitoandesites (Mićić 1980), or alternatively, partly synchronous with the Kopaonik intrusion (Dimitri- jević 1997).

Dejan Ivezić, Marija Živković, Dimitrije Manić, Aleksandar Madžarević, Boban Pavlović, Dušan Danilović (2023)The integration of wastewater heat pumps (using purified water) in district heating systems is analyzed in this paper. The simulation procedure is proposed to analyze the impacts of stochasticity of purified water temperature and flow to heat pump integration and operation. The analysis includes calculation of the daily and seasonal coefficient of performance, as well as fossil fuel savings and CO2 emission reduction due to wastewater heat pump use.
