Properties of fly ash and slag from the power plants
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, ...fly ash, slag, physical composition, chemical composition, mineral composition, X-ray diffraction method... mass (%) NT A – m 58 16 10 5 5 3 3 – – 100 NT A – j 66 17 9 3 2 2 – – – 99 NT B – m 50 17 12 6 4 7 4 – – 100 NT B – j 50 10 14 8 6 7 3 – 2 100 KO A – m 55 7 23 7 – – 4 4 – 100 KO A – j 55 10 12 3 2 10 1 7 – 100 KO B – m 55 19 13 5 – – 5 3 – 100 KO B – j 50 6 15 2 2 10 5 10 – 100 NT A (s) 56 21 11 3 – – ...

Connections between the Levant and the Balkans in the late Middle Pleistocene: Archaeological findings from Velika and Mala Balanica Caves (Serbia)

Rink, Senka Plavšić, Mirjana Roksandić (2022)Major changes in the technological, economic, and social behavior of Middle Pleistocene hominins occurred at the onset of the Middle Paleolithic, 400e200 ka. However, until recently it was not possible to establish when, where, and how certain forms of Middle Paleolithic behavior appeared and spread into Southeastern Europe, mainly owing to gaps in the Paleolithic record. Here we report new results of dating, material culture, and the archaeological context of finds from the Balanica Cave Complex in Sicevo (Serbia). ...Dušan Mihailović, Steven L.

Asbestos-Based Pottery from Corsica: The First Fiber-Reinforced Ceramic Matrix Composite
Asbestos-containing pottery shards collected in the northeast of Corsica (Cap Corse) and dating from the 19th century, or earlier, have been analyzed by SEM-EDS, XRPD, FTIR and Raman microspectroscopy. Blue (crocidolite) and white (chrysotile) asbestos fiber bundles are observed in cross-sections. Most of the asbestos is partly or totally dehydroxylated, and some transformation to forsterite is observed to occur, indicative of a firing above 800 C. Examination of freshly fractured pieces shows a nonbrittle fracture with fiber pull-out, consistent with ...... 1500- 8 š ž Fi 1000- E 500- ok——— | Tremolite, 01-086-1319. j | i I\\\„\M ML _L ı . j ıl | I[SWVi | THE - Diopside, 00-017-0318. j L | l a · || ı - Actinolite, heated, 01-089-5367 i ii | uartz, 00-001-0649 j ı ı ı | 3 Talc 1A, 01-082-8123 i dı ı a |l ' 10 20 30 40 50 60 70 ...

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 ...... Snowdon, Am. Assoc. Petrol. Geol. Bull. 83 (1999) 1426 17. J. M.

Fuzzy expert analysis of the severity of mining machinery failure
Mining machinery failure is almost an everyday occurrence. Usually the failures bare certain consequences, which require additional financial costs to repair and restore the system to its operational state. The consequences are viewed through negative and damaging effects a failure has on the machine, health and safety of the employees, work environment, and on the environment. The removal of the consequences of the failure requires additional financial investment, which has a negative impact on the company’s business. In order ...Dejan V.

Crystallography and Surface Oxidation of Stoichiometric Arsenopyrite from Šumadija-Kopaonik Pb-Zn/Polymetallic Ore District (Serbia)
Ivana Jelić, Aleksandar Pačevski, Aleksandar Kremenović, Aleš Šoster, Andreja Šestan, Janez Zavašnik (2023)The behaviour and stability of arsenopyrite largely depend on its crystal structure, but studies of crystallography and structural defects are scarce. For clarification, we investigated a series of natural arsenopyrite crystals from the polymetallic Pb-Zn-(±Cu,Ag,Au,Sb,Bi,W) Šumadija-Kopaonik ore district (Serbia) by powder X-ray diffraction (XRPD). Among them, samples from the Drenjak gold mineralisation showed near-stoichiometric FeAsS composition and were further investigated by conventional and high-resolution transmission electron microscopy methods.

Површинско распадање керсантита из Тешића мајдана у корелацији са начином обраде на примеру малог степеништа (Београдска тврђава)
Невенка Новаковић (2024)Архитектуру Београда на прелазу 19. у 20. век обележила је употреба керсантита из каменолома Тешића мајдана. Kao камен високих декоративних својстава, керсантит је коришћен за јавне споменике, делове или потпуну изградњу објеката (Народна скупштина Србије, Мало степениште, Народни музеј и др.). Како очување споменика културе изискује познавање својстава уграђеног камена, истраживања су обухватила детаљно проучавање петролошких, хемијских и физичких карактеристика керсантита из Тешића мајданa и узорака камена из споменика Мало степениште (студија случаја). Након детаљног мапирања стања керсантита, лабораторијских ...керсантит, Мало степениште, споменик културе, архитектонски камен, физичко-хемијско распадање, мапирање, форме распадања, површинска обрадаНевенка Новаковић.
