Multiphase evolution of fluids in the Rudnik hydrothermal-skarn deposit (Serbia): new constraints from study of quartz-hosted fluid inclusions
This study presents and discusses first detailed petrographic, microthermometric and Raman spectroscopic data from quartzhosted fluid inclusions at Rudnik Zn-Pb-Cu-Ag skarn deposit (Serbia) and combines them with the information on skarnand ore paragenesis. Three periods in the metamorphic-hydrothermal history of the deposit are recognized: 1) the pre-ore prograde skarn period when garnet-clinopyroxene skarns formed, 2) the syn-ore period that encompasses a retrograde stage marked by epidote and zoisite and a quartz-sulfide stage characterized by quartz, pyrrhotite, sphalerite, galena and ...skarnovska ležišta, rudnik, fludine inkluzije, srpska kenozojska magmatska provincija, Zapadno Tetisjki metalogenetski pojasStefan Petrović, Ronald J.

Дефинисање геотехничких параметара еолских седимената земуснког платоа на основу лабораторијских и теренских SPT испитивања
Ђорђе Крзман (2024)Циљ овог рада је био да се одреде геотехничке караткеристике предметног терена што представља полазну основу за рационално пројектовање и градњу. Истражним бушењем утврђено је да предметни терен изграђују четри лесна хоризонта и три слоја погребене земље до дубине од 22-23 m. Лабораторијским испитивањем добијени су ефективни параметри смичуће чврстоће, где се кохезија најчешће креће између c’=14 и 18 kPa, а угао унутрашњег трења f'= 25 - 30 °.

Research on influence of track stiffness on development of rail squat defects
This paper presents research aiming to establish the relationship between track stiffness and the appearance and development of squat defects on running rails. Uneven incidence of squat defects was observed on the rails of the investigated main transit track in arailway station. Inspection of track support conditions was conducted using an electrometric method. The comparative analysis of the research results indicated a correlation between the incidence of squats and the changes in track support stiffness. The electrometric profiles and ...Milica Mićić, Zdenka Popović, Luka Lazarević, Dejan Vučković, Ljiljana Brajović.

Using English Baits to Catch Serbian Multi-Word Terminology
In this paper we present the first results in bilingual terminology extraction. The hypothesis of our approach is that if for a source language domain terminology exists as well as a domain aligned corpus for a source and a target language, then it is possible to extract the terminology for a target language. Our approach relies on several resources and tools: aligned domain texts, domain terminology for a source language, a terminology extractor for a target language, and a ...aligned texts, word alignment, terminology extraction, electronic dictionaries, morphological inflectionCvetana Krstev, Branislava Šandrih, Ranka Stanković.

The State and Perspective of Belgrade District Heating System Development
Dejan Ivezić, Marija Živković, Aleksandar Madžarević, Fethi Silajdžić, Samra Arnaut, Goran Đelić (2019)District heating (DH) system in Belgrade provides energy for heating of more than 21 million m2 in households (app. 50% of all households), public, commercial and industry sectors. Public Utility Company “Beogradske elektrane” is responsible for all segments of the DH system operation. The system is fueled mostly by natural gas. The share of renewables is negligible. The research analyzes effects of implementation of two main projects proposed in the Development Strategy of the PUC - the introduction of ...Dejan Ivezić, Marija Živković, Aleksandar Madžarević, Fethi Silajdžić, Samra Arnaut, Goran Đelić .

Утицај похабаности резних елемената роторног багера на ниво вибрација погона за копање
Филип Милетић (2023)У докторској дисертацији је анализиран утицај похабаности резних елемената роторног багера на потрошњу електричне енергије и ниво амплитуде вибрација погона за копање. Креиран је модел који у функцији стања резних елемената дефинише зависност разматраних физичких феномена. За развој модела примењене су једначине теорије осцилација и Ватметарска метода [1] којом се одређује потрошња електричне енергије. За верификацију модела извршена су мерења на роторном багеру SRs2000.32/5+VR ангажованом на откопавању откривке на површинском копу Тамнава–Западно поље. Обављено је пет мерења.
