  • Application of Expansive Mortars for the Formation of Artificial Screens During Blasting in Urban Areas

    Milanka Negovanović, Lazar Kričak, Stefan Milanović, Nikola Simić, Jelena Majstorović (2024)
    During construction of buildings in urban areas, sometimes there is a need to blast solid rock mass in the immediate vicinity of the surrounding buildings. In that case, the aim is not only to increase the efficiency of blasting, but also to reduce harmful effects of ground vibration induced by blasting. At the same time, it is very important to protect the buildings located in the safe zone from the blast site as well as remaining rock mass around ...

  • Jeleč grad- još nepriznati objekat geonasleđa

    Marija Radisavljević, Danica Srećković Batoćanin, Vladan Vidosavljević, Irena Kajtez (2022)
    Остаци средњовековног града Јелеча на једном од врхова планине Рогозне (1262 m), по неким веровањима представљаju купу угашеног вулкана. Рогозна je позната по појавама скарновске Cu–Au минерализације, а трагови рударске активности и важних путева још од античких времена и даље постоје у непосредној околини. О томе сведочи и османски назив за Рогозну: Gümüş Dağ (Сребрна планина). Време изградње Јелеча је непознато. Постоје индиције да је постојао још у 6. веку, али се помиње први пут средином 12. века. Поуздан податак ...

  • The Dictionary of the Serbian Academy: from the Text to the Lexical Database

    Ranka Stanković, Rada Stijović, Duško Vitas, Cvetana Krstev, Olga Sabo (2018)
    In this paper we discuss the project of digitization of the Dictionary of the Serbo-Croatian Standard and Vernacular Language. Scanning and character recognition were a particular challenge, since various non-standard character set encoding was used in the course of the almost 60-year long production of the dictionary. The first aim of the project was to formalize the micro-structure of the dictionary articles in order to parse the digitized text of and transform it into structured data stored in relational lexical database. This approach ...

  • Inhibitory effect of platinum and ruthenium bipyridyl complexes on porcine pancreatic phospholipase A2

    Tina Kamčeva, Jörg Flemmig, Bojana Damnjanović, Jürgen Arnhold, Aleksandar Mijatović, Marijana Petković (2011)
    Fosfolipaza pankreasa A2 (PLA2) igra važnu ulogu u ćelijskoj homeostazi kao iu procesu karcinogeneze.

  • Automatic construction of a morphological dictionary of multi-word units

    Cvetana Krstev, Ranka Stanković, Ivan Obradović, Duško Vitas, Miloš Utvić (2010)
    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 ...

  • The different approaches in seismic stratigraphy interpretation

    Dejan Radivojević (2018)
    U tekstu su prikazana dva osnovna pristupa u seizmostratigrafskoj interpretaciji. Prvi kao polaznu osnovu ima seizmičke sekcije, čija se interpretacija u kasnijoj fazi koreliše sa bušotinskim podacima. Drugi u prvoj fazi analizira podatke dobijene dubokim bušenjem koji se kasnije korelišu sa seizmičkim sekcijama. Prikazan je hronološki redosled i objašnjen postupak pri seizmostratigrafskoj interpretaciji oba pristupa. Ovakav način interpretacije omogućio je naftnim kompanijama detaljnije i preciznije sagledavanje geoloških odnosa, smanjenje rizika istraživanja i racionalnije projektovanje razradnih bušotina.
