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 ...... (Figures 4, A1 and A?2). Table 2 summarizes the phases identified. The FTIR spectra of asbestos in the O-H and H»O stretching, range (3000–4000 cm !) only show narrow peaks characteristic of O-H vibrations [43]. In our case, strong and broad ~3200 and 3400 cm-! bands are dominant, which are typical ...

Branko M. Petrović (2016-07-12)Rotorni bageri su mašine koje se u današnje vreme najviše primenjuju uprocesu masovne eksploatacije uglja zahvaljujući, pre svega, nizu tehničkoeksploatacionihprednosti u odnosu na druge vrste bagera. Raznovrsnirudarsko-tehnički zahtevi otkopavanja doprineli su razvoju nekoliko tipova ovihmašina, tako da svaki od njih ima svoje prednosti i nedostatke u odnosu nadrugi tip.Predmet istraživanja u disertaciji odnosi se na izbor optimalnekonstrukcije strele bagera i njene usaglašenosti sa uslovima radne sredine kojiće vladati na površinskim kopovima lignita Srbije, imajući u vidu složene usloveeksploatacije (velika ...površinski kop, parametri bloka, kapacitet, rotorni bager, strelabagera, geomehanika, stabilnost kosina, ekonomija... sledeći način: 𝑄𝑏 = 𝑄𝑡�1+𝑡𝑚𝑡𝑑 �𝑓𝑠 (bm3/h) (2.4) gde su : 𝑄𝑡 – teoretski kapacitet (rm³/h), 𝑡𝑑 – neto vreme kopanja bloka (h), 𝑡𝑚 – vreme manevrisanja tokom kopanja bloka (h), 𝑓𝑠 – faktor bubrenja iskopanog materijala.

Natural two-dimensional pyrophyllite: Nanoscale lubricant, electrical insulator and easily-machinable material
Borislav Vasić, Radoš Gajić, Ivana Milošević, Žarko Medić, Marina Blagojev, Marko Opačić, Aleksandar Kremenović, Dejan Lazić (2022)Pyrophyllite, with the chemical formula Al2Si4O10(OH)2, is a naturally occurring and abundant van der Waals mineral belonging to the group of phyllosilicates. It is very soft, layered crystal used for sculpting and an excellent electrical and thermal insulator aimed for the operation at high pressure and temperature. Here, for the first time, two-dimensional (2D) pyrophyllite obtained by both mechanical and liquid phase exfoliation is presented and investigated at the nanoscale. The layered structure provides low friction coefficient of around ...Atomic force microscopy, Insulating properties, Nanofriction and wear, Natural two dimensional materials, Phyllosilicates, PyrophylliteBorislav Vasić, Radoš Gajić, Ivana Milošević, Žarko Medić, Marina Blagojev, Marko Opačić, Aleksandar Kremenović, Dejan Lazić.

Cytotoxic activity of tetradentate Schiff Base Copper(II) complexes
Istraživanje kompleksa bakra kao potencijalnih antikancerogenih agenasa nudi ohrabrujuće perspektive u odnosu na komplekse platine (II) računajući na smanjenu toksičnost, novi mehanizam delovanja, različit spektar aktivnosti i perspektivu neunakrsne rezistencije. Kompleksi Šifovih baza bakra(II) koji sadrže tetradentatne ligande acac2en tipa (acac2en (1); tfacac2en (3), acactfacacen (4), acacphacacen (6)) pokazali su važnu antioksidativnu aktivnost, visok potencijal za interakciju sa HSA i DNK, u prethodnim studijama.

Mehanizam nastanka bjelasičke klipe u internim Dinaridima severne Crne Gore
Katarina Stefanović (2024)Bjelasička klipa predstavlja segment Internih Dinarida na području severne Crne Gore. Područje obuhvata tektonski kontakt Drinsko-ivanjičke jedinice i Istočnobosansko-durmitorske jedinice, pri čemu se na širem području nalaze i jedinice Prekarst i Zona bosanskog fliša. Tektonska klipa Drinsko-ivanjičke jedinice, odnosno bjelasička klipa, kao i generalna tektonska evolucija područja u kom se ona nalazi, nisu izučeni u adekvatnoj meri.

Fuzzy Model for Risk Assessment of Machinery Failures
The main goal of this research was the development of an algorithm for the implementation of negative risk parameters in a synthesis model for a risk level assessment for a specific machine used in the mining industry. Fuzzy sets and fuzzy logic theory, in combination with statistical methods, were applied to analyze the time picture state of the observed machine. Fuzzy logic is presented through fuzzy proposition and a fuzzy composition module.

Clockwise vertical-axis rotation in the West Vardar zone of Serbia: Tectonic implications
The Vardar-Tethyan mega-suture between the Eurasian and Adria (Gondwana) margins comprises remnants of oceanic lithosphere of Neotethys and distal parts of the adjacent continental margins including unconformable Late Cretaceous sedimentary cover and Cenozoic igneous rocks of post-obduction age.

Modeliranje disperzije dimnih gasova iz termoelektrane Kostolac B
Bojan Živanović (2024)Bez hrane se može preživeti nedelju dana, bez vode svega nekoliko dana, međutim, bez vazduha se može preživeti najmanje, nekoliko minuta. Pitanje je kakav uticaj na zdravlje čoveka i okoline ima vazduh koji je lošeg kvaliteta, a kojem je skoro celokupno stanovništvo planete izloženo? Ovaj rad se bavi problematikom modeliranja disperzije dimnih gasova iz novog bloka B3 TE ,,Kostolac’’ B. Ključni momenti koji će biti predstavljeni jesu zagađenje, zdravstveni efekti, modeliranje disperzije i analiza dobijenih rezultata korišćenjem programa AERMOD. Analiziran ......

Bezbednosna rastojanja u jamskim magacinima eksploziva u domaćoj i međunarodnoj praksi
Projektovanje jamskih magacina eksploziva predstavlja složen inženjerski problem. Sama namena jamskih magacina zahteva ispunjenost niza uslova koji se odnose na bezbedno pozicioniranje magacina, ispunjenost uslova ventilacije, pristupa, rukovođenja magacinom, načina skladištenja eksplozivnih sredstava, protivpožarne zaštite, elektro zaštite itd. Veoma važan parametar prilikom projektovanja jamskih magacina eksplozivnih sredstava predstavlja minimalno sigurnosno rastojanje između susednih komora u kojima su smeštena eksplozivna sredstva u cilju sprečavanja potencijalnog neželjenog dejstva vazdušnog udarnog talasa, razornog dejstva eksplozije i seizmičkog dejstva eksplozije.

Classification of Terms on a Positive-Negative Feelings Polarity Scale Based on Emoticons
Mihailo Škorić (2017)The goal of this paper is to draw attention to the possibility of using emoticon-riddled text on the web in language-neutral sentiment analysis. It introduces several innovations in the existing framework of research and tests their effectiveness. It also presents a software tool especially made for that purpose, explains how it builds a database with sentimental value of terms and offers the user manual. Finally, it presents a software tool that tests the new database and gives some examples ...... with a neu- tral character string yy, so that they wiil not be mistaken for :/ emoticon. Finally, regular expressions [a|h|A|H][a|h|A|H][h|H][a|A][h|H][a|h|A|H] and [h|H][a|A][h|H][a|A] are used to find as many different examples of expres- sion of laughter, and the expressions found are replaced with ...Mihailo Škorić.
