  • Моделирање дисперзије прашине у фази одлагања флотацијске јаловине у руднику “Шупља стијена”

    Вања Живановић (2024)
    Рударство, као једна од кључних индустрија у многим земљама света игра важну улогу у стварању економске вредности али истовремено и велики притисак на животну средину. Процеси експлоатације и обраде руде често укључују употребу разних хемикалија, што може изазвати загађење земљишта, воде и ваздуха. Очување животне средине постаје све важније питање у свету у којем се суочавамо са изазовима као што су климатске промене, деградација земљишта, губитак биодиверзитета. Моделирање дисперзије загађења животне средине представља процес у ком се коришћењем математичких модела ...

  • Upravljanje resursima podzemnih voda severne Bačke

    Bojan B. Hajdin (2013-03-07)
    Vodosnabdevanje gradova i naselja severne Bačke vrši se u potpunosti iskorišćavanjempodzemnih voda. Najznačajnije količine podzemne vode namenjene za piće zahvatajuse iz izdani u vodonosnim pleistocenskim naslagama koje su poznate kao osnovnivodonosni kompleks, dok su danas u vodosnabdevanju manje zastupljene vode izizdani u pliocenskim sedimentima i prve, slobodne izdani rasprostranjene plitko ispodpovršine terena.Pored snabdevanja stanovništva, veliki potrošači podzemne vode su i industrijskapreduzeća, a zbog loših uslova i nerazvijenih sistema za navodnjavanje sve veći korisnicivoda prve izdani postaju i poljoprivredni proizvođači.Geološka ...

  • Petrološke karakteristike dunavskog šljunka (Beograd – Zemun)

    Miloš Mihajlović (2024)
    Dunavski šljunak u okolini Zemuna karakterističan je za obalne rečne naslage formirane dugotrajnim procesima erozije i transporta materijala koje reka Dunav nosi sa različitih područja uzvodno. Ispitivanja šljunka sa lokacije „Gemax” su pokazala je šljunak uglavnom zaobljen, najčešće u rasponu od nekoliko milimetara do nekoliko centimetara u prečniku. Kako Dunav nosi materijal sa velikog sliva, ovaj šljunak sadrži raznovrsne sastojke sa dominacijom kvarca i odlomaka stena visokosilicijskog sastava. Mineraloško-petrografska ispitivanja pokazala su prisustvo klasta različitog sastava, čime je potvrđena ...

  • The use of biological markers in determination of origin and type of organic matter in the Tisza river sediments

    Snežana Štrbac, Gordana Gajica, Aleksandra Šajnović, Nebojša Vasić, Ksenija Stojanović, Branimir Jovančićević (2013)
    The objective of the study was to determine the origin and type of organic matter (OM) of the Tisza recent sediments along the distance of 153 km through the territory of Serbia. For this purpose group organic-geochemical parameters and biomarker compositions were used. All samples contain approximately same amount of OM, which was deposited under uniform, slightly reducing conditions. Based on the distribution of n-alkanes, the origin and type of OM could not be precisely estimated. However, n-alkane patterns ...

    The research presented in this paper aims at creating a bilingual (sr-en), easily searchable, hypertext, born-digital, corpus-based terminological database of raw material terminology for dictionary production. The approach is based on linking dictionaries related to the raw material domain, both digitally born and printed, into a lexicon structure, aligning terminology from different dictionaries as much as possible. This paper presents the main features of this approach, data used for compilation of the terminological database, the procedure by which it has ...

  • Properties of fly ash and slag from the power plants

    Miloš Šešlija, Aleksandra Rosić, Nebojša Radović, Milinko Vasić, Mitar Đogo, Milovan Jotić (2016)
    This paper describes the physical, chemical and mineral properties of ash and slag, which were taken from thermal power plants Nikola Tesla A, Nikola Tesla B, Kostolac A and Kostolac B. The knowledge of the mineralogical material composition is important because the type of minerals directly determines the properties of the fly ash and slag and their possible application. Laboratory tests showed that ash and slag samples consist of the following minerals: amorphous materials, quartz, feldspar, mullite, melilite, cristobalite, ...
