Mogućnost korišćenјa toplotnih pumpi sa otpadnom toplotom iz postrojenјa za prečišćavanјe otpadnih voda kao toplotnim izvorom
U narednom periodu se planira izgradnja nekoliko desetina sistema za prečišćavanje otpadnih voda u većim gradovima u Srbiji. Iskustva iz postrojenja koja su trenutno u radu, pokazuju da bi prečišćena otpadna voda, s obzirom na protok i temperaturu, mogla da predstavlja značajan izvor obnovljive energije. U radu su prikazani primeri dobre prakse korišćenja ove energije u sistemima daljinskog grejanja u zemljama Evropske unije. Analiziran je rad postrojenja za prečišćavanje otpadnih voda u Šapcu i razmotrena je mogućnost njegovog korišćenja ...... korišćenja toplotnih pumpi sa otpadnom toplotom iz postrojenja za prečišćavanje otpadnih voda kao toplotnim izvorom Possibilities for Utilization of Waste Heat from Wastewater Treatment Plants by Heat Pumps Dejan Ivezić, Marija Živković, Aleksandar Madžarević, Boban Pavlović Univerzitet u Beogradu ...Dejan Ivezić, Marija Živković, Aleksandar Madžarević, Boban Pavlović.

Analiza uporednog praćenja temperature površine ohlađenih materijala pri njihovom zagrevanju do ambijentalne temperature
U datom eksperimentalnom radu su termografskim metodama ispitivane termofizičke karakteristike različitih materijala. Za ispitivanja su izabrani mesingani niovčić, ugalj i pelet, jer imaju različita termoizolaciona svojstava i različito stanje površine. Uzorci su najpre hlađeni, a zatim je njihovo zagrevanje na sobnoj temperaturi praćeno termalnom kamerom. U drugom delu eksperimenta, korišćena je impulsna termografija, a zagrevanje površine uzoraka vršeno je svetlosnom pobudom.Stevan Đenadić, Ljubiša Tomić, Vesna Damnjanović, Katarina Nestorović.

Composition of organic matter and thermal maturity of Mesozoic and Cenozoic sedimentary rocks in East Herzegovina (External Dinarides, Bosnia and Herzegovina)
This paper presents the first data on the organic matter and thermal maturity of Mesozoic and Cenozoic sedimentary rocks in the East Herzegovina region of the External Dinarides. Representative, organic-rich samples from outcropping sedimentary rocks of different ages in the area (Triassic to Neogene) were selected and analysed. The organic matter was studied by Rock-Eval pyrolysis and under the microscope in reflected non-polarized light and incident blue light. The results obtained show the presence of different types of organic ...... the original S1 (hence PI and to a lesser extent TOC), it was presumed that there was also a relative increase of S2 and HI, due to the presence of solid bitumen and heavy/asphaltic oil.

... generative potential (S2) in most samples is thus a result not only of the cracking of kerogen, but also of bitumen.

Quantitative landslide risk assessment in the city of Tuzla
In the climate-changing conditions, geological environment interacts more dramatically with the urban fabric than before. The urbanization is expansive and more aggressive than before, but so are the weather extremes and long-term climate trends. In effect, many processes which can be triggered by either side, nature or engineering, are becoming more pervasive than before, and such is the case with landslides. Dealing and managing landslides requires few crucial steps, starting from collecting data on landslide location and typology – ...... includes open pit coal and underground salt mining. Both mining types can affect stability by causing subsidence (m order of magnitude) or producing waste deposits that are fine-grained non-cohesive but unstable when saturated. Distance to mining is a numeric proxy, which was normalized to meet 0-1 ...Miloš Marjanović, Biljana Abolmasov, Cvjetko Sandić, Miralem Mulać, Petar Begović.

The Usage of Various Lexical Resources and Tools to Improve the Performance of Web Search Engines
In this paper we present how resources and tools developed within the Human Language Technology Group at the University of Belgrade can be used for tuning queries before submitting them to a web search engine. We argue that the selection of words chosen for a query, which are of paramount importance for the quality of results obtained by the query, can be substantially improved by using various lexical resources, such as morphological dictionaries and wordnets. These dictionaries enable semantic ...LR web services, MultiWord Expressions & Collocations, Information Extraction, Information Retrieval... queries are of no interest since they represent simple lists of key words, for instance Beograd, Gradska čistoća, privatizacija ‘Belgrade, City Waste Disposal, privatization’.

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.

Multiple-Criteria Decision-Making in Mine Development Planning
Sanja Bajić (2023)The Borska Reka ore deposit is an experimental location where developed methodologies have been applied. It is the largest ore body within the Bor mining complex, which has been the subject of numerous studies and analyses for more than three decades. The paper focuses on the application of FAHP and the VIKOR method to address ranking of alternatives and select the optimal mining method by means of fuzzy multicriteria optimization.Sanja Bajić.
