Eksploatacioni učinci ugljenih sistema na površinskom kopu Tamnava–Zapadno polje
U radu su analizirani eksploatacioni učinci ugljenih sistema na površinskom kopu Tamnava–Zapadno polje. Period analize je prvih šest meseci tekuće godine. Analiza je vršena sa aspekta ostvarene proizvodnje, kvaliteta uglja, efektivnog vremena rada, kapacitetnog i vremenskog iskoršćenja i zastoja sistema. Za poređenje podataka različitih parametara koji po svojoj prirodi nisu međusobno uporedivi, u radu su korišćene metode višekriterijumskog odlučivanja.... uglja prema otkopanoj količini proslojaka peska i gline.

Palaeoflora of Kamenica (Pranjani Basin, western Serbia)
Palaeofloras of the Paleogene in Serbia are relatively rare, especially in comparison with floras from Neogene sediments. Most Paleogene phytoas sociations from the territory of Serbia existed in a dry and warm climate. The youngest Paleogene phytoassociation originates from the Pranjani Basin (Western Serbia), locality Kamenica. The age of this palaeoflora is determined as Late Oligocene. This fossil plant assemblage is different from other Paleo gene phytoassociations.The palaeoflora from Kamenica is characterized with leaf imprints larger than in other ...... leaves – a physiognomic analysis of european vegetation.

Conversion of land areas after coal mine closure and reclamation
Otkopavanje uglja površinski i podzemno praćeno je degradacijom zemljišta, promenom formiranja predela i izmenom flore i faune. Od velikog značaja je razvoj novih naučno utemeljenih pristupa obnovljanje antropogeno poremećenih predela zasnovanih na formiranju rekultivacionih i rudarskih tehnologija. Apsolutno je neophodno obezbediti sveobuhvatno kvalitetno očuvanje zemljišnih i vodnih resursa i odrediti rekultivisano zemljište za novu namenu.

The Content of Toxic Metals in Agricultural Produce near a Coal Mine: Case Study KCB in Lazarevac, Serbia
Праћење и анализа концентрација токсичних метала (олово и кадмијум) у земљишту и усевима указују на то да пољопривредно земљиште у Србији углавном није загађено, а квалитет земљишта је природно добар. Због тога су таква земљишта погодна за органску пољопривреду. Сви уочени случајеви контаминације токсичним металима су само локалне природе, а резултат су ђубрива и пестицида, комуналног отпада, издувних гасова, оближњих производних објеката, топионица, рудника, јаловишта итд.

Indexing of textual databases based on lexical resources: A case study for Serbian
In this paper we describe an approach to improvement of information retrieval results for large textual databases by pre-indexing documents using bag-of-words and Named Entity Recognition. The approach was applied on a database of geological projects financed by the Republic of Serbia in the last half century. Each document within this database is described by metadata, consisting of several fields such as title, domain, keywords, abstract, geographical location and the like. A bag of words was produced from these ...... archiving of geologic data, and provide a modern and effective in- formation basis for carrying out all activities related to planning, design and decision-making in the field of geology.

Frequency and Length of Syllables in Serbian
Marija Radojičić, Biljana Lazić, Sebastijan Kaplar, Ranka Stanković, Ivan Obradović, Ján Mačutek, Lívia Leššová (2019)Basic analyses of several properties of syllables (the rank-frequency distribution, the distribution of length, and the relation between length and frequency) in Serbian is presented. The syllabification algorithm used combines the maximum onset principle and the sonority hierarchy. Results indicate that syllables behave similarly to words as far as mathematical models are concerned, but values of parameters in models for syllables are quite different from those for words.... all of them (and also to many other languages). Our data support the hypothesis suggested by Strauss et al. (2008), according to which syllables, as far as models are concerned, behave like words. Syllables in the Serbian text under analysis „mimic“ the behaviour of words with respect to their f ...

As several other Poisson-like distributions also fit the data very well, we postpone any attempts to formulate conclusions that could be deduced from the model and parameter values until data for more languages are available.
