The impact of calculation of resources and reserves on mining activity in Serbia
The appearance of interest of the world's most important mining companies i for investment in Serbia imposes the problem of harmonization of domestic legislation with foreign ones. In this paper, specific categorization and classification of mineral raw materials, which do not match in domestic and foreign practice, are treated. The existence of such a conflict of criteria in use for categorization and classification can lead to misunderstanding and create certain complications in business. The following sections outline some of ...geological exploration, deposits, solid mineral raw materials, mineral projects, mineral resources and reservesJelena Zakonović, Katarina Urošević, Radmila Gaćina.

Energetska bezbednost sektora prirodnog gasa Srbije
U prve dve decenije 21. veka obezbeđivanje sigurnosti snabdevanja prirodnim gasom domaćeg tržišta bio je jedan od prioriteta razvoja energetike Srbije. Istovremeno, aspekt sigurnog snabdevanja bio je neizostavni deo slagalice stvaranja energetske bezbednosti. Izražena uvozna zavisnost je dominantna karakteristika sektora prirodnog gasa, tačnije, Republika Srbija je snažno zavisna od ruskog gasa, sa više od 80% uvezenih količina gasa, a do pre dve godine snabdevala se isključivo kroz jednu interkonekciju.

Prognozna ocena resursa kaolinitskih glina u sedimentnim basenima Srbije
Vladimir M. Simić (2003)Kaolinitske gline predstavljaju jednu od privredno najznačajnijih nemetaličnih mineralnih sirovina u Srbiji. Ležišta tih glina odavno se istražuju i eksploatišu u Aranđelovačkom i Kolubarskom basenu i basenima vlašićkog antiklinorijuma. Osim toga, u većem ili manjem obimu istražene su mnoge lokalnosti, a na nekima od njih vršila se povremena eksploatacija. Dosadašnja istraživanja kaolinitskih glina imala su, međutim, prevashodno uzak istraživački cilj - utvrđivanje rezervi glina određenog ležišta, dok su istraživanja regionalnog karaktera bila malog obima i vezana za delove pojedinih ...prognozna ocena, resursi kaolinitskih glina, sedimentni baseni, Srbija, geologija, mineralogija, kvalitet, potencijalnostVladimir M.

Процјена хазарда и ризика од клизишта за различите нивое просторног планирања у Републици Српској, БиХ
Цвјетко С. Сандић (2022)Територија Републике Српске је у посљедних десетак година веома угрожена активирањем нових и реактивирањем старих клизишта. Она својим дјеловањем наносе огромне материјалне штете, па и људске жртве, те је неопходно озбиљније третирање и дјеловање у борби са овим природним хазардом. Чест проблем јесте одговорност, тј. надлежност институција из ове области и недостатак у законској регулативи која готово никако или само површно обрађује област хазарда и ризика од клизишта.

U-Pb zircon geochronology of the Paleogene – Neogene volcanism in the NW Anatolia: Its implications for the Late Mesozoic-Cenozoic geodynamic evolution of the Aegean
E. Yalçın Ersoy, Cüneyt Akal, Ş. Can Genç, Osman Candan, Martin R. Palmer, Dejan Prelević, İbrahim Uysal, Regina Mertz-Kraus (2017)The northern Aegean region was shaped by subduction, obduction, collision, and post-collisional extension processes. Two areas in this region, the Rhodope-Thrace-Biga Peninsula to the west and Armutlu-Almacık-Nallıhan (the Central Sakarya) to the east, are characterized by extensive Eocene to Miocene post-collisional magmatic associations. We suggest that comparison of the Cenozoic magmatic events of these two regions may provide insights into the Late Mesozoic to Cenozoic tectonic evolution of the Aegean. With this aim, we present an improved Cenozoic stratigraphy ...E. Yalçın Ersoy, Cüneyt Akal, Ş. Can Genç, Osman Candan, Martin R. Palmer, Dejan Prelević, İbrahim Uysal, Regina Mertz-Kraus.

Vulnerability methods in hard rock formation as a basis for groundwater risk assessment – from resource to source
Groundwater in a hard rock formation is most endangered at places where a potential source can discharge contaminants that can reach the saturated zone of an aquifer. In these circumstances, an essential tool for groundwater protection is the contamination risk map. This map is based on the integration of two maps: a hazards map, i.e., map of potential sources of contamination and a vulnerability map. The selection of a proper vulnerability method is an important task since the resulting ...karta rizika od kontaminacije, ranjivosti podzemnih voda, DRASTIC, EPIK, PI, COP, Nacionalni park TaraVladimir Živanović, Igor Jemcov, Veselin Dragišić.

The influence of alkyl polyglucosides (and highly ethoxylated alcohol boosters) on the phase behavior of a water/toluene/technical alkyl polyethoxylate microemulsion system
Marija Ilic, Franz-Hubert Haegel, Vesna Pavelkic, Dragan Zlatanovic, Snezana Nikolic-Mandic, Aleksandar Lolic, Zoran Nedic (2016)The influence of additives (alkyl polyglucoside, Glucopon 600 CS UP and alcohol ethoxylate C18E100) on the behavior of the water/toluene/Lutensol ON 50 (technical oxoalcohol, i-C10E5) microemulsion system as a function of temperature and composition has been investigated. The phase behavior of the microemulsions was determined by vertical sections through the Gibbs phase prism (fish-like phase diagrams). Alkyl polyglucoside shifts the one phase region to lower temperatures compared with water/toluene/Lutensol ON 50 mixtures.

Reducing environmental impact caused by mining activities in limestone mines
Radmila Gaćina, Bojan Dimitrijević (2022)Mining and its related activities have always resulted in changes in the environment and these changes can vary from one area to another. As a result of mining, several types of changes can be distinguished: destruction of land and existing vegetation, changes in terrain topography, modification in air quality, changes in surface and groundwater quality, as well as change geotechnical conditions of the rock. Environmental impact of mining have been a public concern. There is widespread global interest in mining ...Radmila Gaćina, Bojan Dimitrijević.
