Availability as a dimension of energy security in the Republic of Serbia
Boban Pavlović, Dejan Ivezić (2016)There is a range of modern approaches and models in literature for the evaluation and determination of energy security, which are based on different parameters and indicators. For most of them, a common characteristic is emphasizing the avail ability of energy, as an important dimension for ensuring energy security. In this paper, concise overview of Serbian energy sectors is given and appropriate energy indicators are defined and determined. Selected indicators provide insight into the main components that characterize availability ...... faculty publications available in open access, as well as the employees' publications. - The Repository is available at: www.dr.rgf.bg.ac.rs Pavlović, B., et al.: Availability as a Dimension of Energy Security in the Republic of Serbia THERMAL SCIENCE: Year 2017, Vol. 21, No. 1A, pp. 323-333 323 AVAILABILITY ...

Simple 2D gravity–density inversion for the modeling of the basin basement: example from the Banat area, Serbia
We have developed a technique to calculate lateral density distribution of the sedimentary basin basement by combining linear gravity–density inversion and 2D forward modeling. The procedure requires gravity anomaly data, depth-to-basement data and density data for the sediments (density–depth distribution). Gravity efect of density variations in the basement was extracted from the total gravity anomaly by removing the joint efect of the sediments with vertical density variations and homogeneous basement of average density contrast (calculated by 2D modeling). Gravity ...Ivana Vasiljević, Snežana Ignjatović, Dragana Đurić.

Pleistocene rhinoceros from Bogovina Cave: the first report of Stephanorhinus hundsheimensis Toula, 1902 (Mammalia, Rhinocerotidae) from Serbia
Finds of Pleistocene rhinoceros are rare in Serbia, and only one species (the woolly rhinoceros Coelodonta antiquitatis Blumenbach, 1799) has been reported so far. The current paper presents the dental material of an extinct so-called Hundsheim rhinoceros, Stephanorhinus hundsheimensis Toula, 1902 from Bogovina Cave (East ern Serbia). Both the morphological and metric characteristics of the teeth are consis tent with the attribution to S. hundsheimensis.

Prioritization of strategic measures for strengthening the security of supply of the Serbian natural gas sector
To strengthen the security of supply of the Serbian gas sector, it is necessary to analyze the impact of planned strategic measures. The analysis involves the identification of the most influential threats to the security of natural gas supply and prioritization of the strategic measures for overcoming the consequences of threats. The proposed methodology is based on Fuzzy Analytic Hierarchy Process. The obtained weights for the identified threats and strategic measures are formed according to experts' judgments.

Atmospheric exposure vs burying: influences on damage intensity of built-in kersantite in the monument of the Small Staircase (Belgrade, Serbia)
Proučavan je efekat „zatrpanog kamena“ na intenzitet procesa degradacije prisutnih na kersantitu koji je ugrađen u spomenik Malo stepenište. Istraživanja su vršena na uzorcima stene iz kamenoloma i na oštećenim kamenim blokovima ugrađenim u spomenik. Dok su neki delovi stepeništa bili pod zemljom 90 godina, većina kamenih elemenata je bila izložena različitim uslovima sredine i antropogenim uticajima. Urađeno je detaljno mapiranje trenutnog stanja spomenika kako bi se istražio uticaj “zatrpavanja” i kompleksne geometrije spomenika na tip propadanja i variranje ...Nevenka Novaković, Predrag Dabić, Vesna Matović.

Influence of DEM resolution on numerical modelling of debris flows in RAMMS - Selanac case study
Debris flows induced by intensive rainfall represent very hazardous phenomena in many parts of the World. Methods for prediction of runout distance of flow like mass movements are different and depending on the input data, rheology, and available or appropriate numerical solution. However, sometimes it is not easy to obtain pre event and post event high-resolution data in the rural or mountainous area. Thus, the topology of terrain is the most important input parameter for the every real case ...... heterogeneous in lithological composition, as well as grain size distribution (up to m 3 boulders) (Fig. 3).

Верификација етажних транспортера на угљеном систему – површински коп Дрмно
Тамара Андрејевић (2024)У савременом рударству, површински копови угља наилазе на различите проблеме које треба превазићи зарад добијања потребне количине угља. Као највећи потрошачи овог енергента јављају се термоелектране, где на основу овога можемо да закључимо колико су блиско повезани добра и континуирана производња на површинском копу и рад термоелектрана. Са циљем да се обезбеди стабилна и континуирана производња, потребно је да се направи добар одабир транспортера.

Техно-економска оцена подземног откопавања лежишта бакра применом коморно-стубне методе

Одређивање оптималне производње дубинске пумпе на клипним шипкама
Небојша Савић (2024)Дужи временски период током историје производње нафте, дубинске пумпе на клипним шипкама су први и у многим случајевима једини избор када су у питању механичке методе експлоатације. Правилан одабир сваког појединачног елемента система омогућава оптимизацију која са собом повлачи бенефите у виду повећавања ефикасности и смањења трошкова. Тренутно примењени систем дубинских пумпи на клипним шипкама на лежишту „Н“ обезбеђује стабилну производњу и реализацију годишњих планова производње без већих проблема. У овом раду је приказан начин оптимизације производње дубинским пумпама ...... s3a 6yuiomuny H-016 „ B B B B I U J B E B U Ne tl se qu e (k— e") 08 % W Ž0 M Cesrk Aegie (degrres) m ” _= » 41 RODSTAR 2018 REL 1 \ Theta Olfekd Services, inc. | (gotheta.com) NTC NIS · Naftagas INPUT DATA 'CALCULATED RESULTS (TOTAL SCORE: 78% GRADE: B-) 75 Target Prod (mYD}: ...

Mesozoic carbonate rocks in Serbia used as dimension stone
Vesna Matović, Tijana Vojnović Ćalić (2016)The building industry in Serbia uses, to a great extent, imported natural stone for architectural purposes. The significance of local deposits, particularly limestones, is not adequately perceived despite the country’s abundance of these valuable resources. Therefore, this study focuses on Serbia’s Mesozoic carbonate rocks, specifically on the deposits of four selected quarries: Klisura, Skrzut, Struganik, and Tisnica. The quality and prospects of the application of these limestones has not yet been the subject of a detailed, comprehensive investigation. Therefore, ......

The ‘Umka’ landslide
We present an in-depth landslide map of the ‘Umka’ landslide near Belgrade, Serbia, at a scale of 1:5000. The map delineates elements at risk, primarily buildings and road infrastructure impacted by the landslide displacements of several cm per year, introduced during frequent reactivation stages. The Main map results from a survey of over 350 buildings and more than 7 km of state and local roads. The acquisition techniques included engineering geological field mapping, building survey, and visual interpretation of ...rizik od klizišta, elementi rizika, kartiranje pomoću drona, ispitivanje objekata, geotehnički monitoringUroš Đurić, Dragana Đurić, Miloš Marjanović, Biljana Abolmasov, Ivana Vasiljević.
