Heavy metals in lignite and soil of Kostolac-Kovin coal basin, eastern Serbia - comparative analysis with selected cities in Serbia, region, Europe and world
Bogoljub Vučković, Bojan Dimitrijević (2023)The Kostolac-Kovin coal basin with an area of 320 km2, with 5 separate layers of coal and with a total of about 5.7 Bt of geological resources and reserves represents an exceptional potential for coal production in Serbia. The coal resources listed in this way are not fully exploitable, but they represent potential for consideration. In this paper, we deal with the geochemical characteristics of coal seams and perform a comparative analysis of coal affectation on the environment. With ......

A Lexical Approach to Acronyms and their Definitions
In this paper we present a comprehensive approach to acronyms for Natural-Language Processing (NLP) of Serbian texts. The proposed procedure includes extraction of acronyms and their definitions that are usual Multi-Word Units (MWUs), shallow parsing of MWUs that enables MWU lemmatization and production of entries in morphological electronic dictionaries, both for MWU and acronyms, that are provided with grammatical, syntactic, semantic and domain information. This approach enables representation that reflects complex relations between acronyms and their definitions.... finition patterns within text: towards an automated construction of comprehensive acronym-definition dictionaries.

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 ...... closely to MWEs (Baldwin & Kim, 2010; Frantzi et al., 2000).

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.

Analiza mogućnosti primene tehnologije hvatanja i skladištenja ugljenika (CO2) na objektima Nis-A
Isidora Veljanoski (2024)U ovom radu opisana je primena CCUS tehnologija u kompaniji NIS i na koji način treba da se optimizuje da bi projekat bio rentabilan.U prvom i drugom poglavlju opisani su energetski trendovi i tranzicije, razvojni mehanizmi za regulisanje emisije gasova staklene baste i o ugljen-dioksidu kao hemijskom jedinjenju i šta je to CCUS.U trećem, četvrtom i petom poglavlju je detaljnije opisano izdvajanje, hvatanje, transport i skladištenje ugljen-dioksida.Šesto poglavlje i sedmo poglavlje obuhvataju rešenja za razvoj i realizaciju CCUS projekata ...energetski trendovi, ugljen-dioksid, CCUS, izdvajanje, hvatanje, transport i skladištenje CO2, ležište, ekonomija projekta... (širenjem sa visokog na atmosferski pritisak) delimično prelazi u čvrsto stanje (suvi led). Ugljen-dioksid ima primenu u: – Industriji, -– Medicini. Il 2.1.1 Sadašnje korišćenje ugljen-dioksida Korišćenje CO- u industrijske svrhe: Umesto da se CO jednostavno skladišti ili emituje, moguće ...
