Proračun osnovnih mehanizama na rotornom bageru ShRs 1300 na PK Polje E
Luka Nikolić (2024)Površinska eksoloatacija ležišta mineralnih sirovina, a posebno uglja (lignita) vrši se primenom različitih rudarskih mašina. U zavisnosti od tipa ležišta, rudarsko-geoloških uslova, ekonomske analize i sl. koriste se sistemi sa kontinualnim ili diskontinualnim načinom rada.Kod kontinualnih sistema, primenjuju se kompleksne rudarske mašine kod kojih se proces odvija neprekidno odnosno bez ciklusa utovara, transporta i odlaganja i najčešće rade u sve tri smene. Rotorni bageri i bageri vedričari, transporteri sa gumenom trakom, odlagači ili deponijske mašine čine tkz BTO ili ...... > Debljina reza s= 0,sam Broj podetaža u bloku: >n > — 0,55D — | bDOd — 0,7«D 26 26 > Tood Č 0,5+9 b 0,79 5,8 > moa > 4,1 Tnod = 5 Visina podetaža: 0,5*%DD Visina I podetaže: hI = 0,6 * D = 0,6 * 9 » 5,4 = 5,5[m] Visina ostalih.

Differently shaped nanocrystalline (Fe, Y)3O4 and its adsorption efficiency toward inorganic arsenic species
Biljana P Dojčinović, Boštjan Jančar, Lotfi Bessais, Aleksandar Kremenović, Nataša P Jović-Jovičić, Predrag T Banković, Dalibor M Stanković, Miloš Ognjanović, Bratislav V Antić (2019)Herein we report effects of partial substitution of Fe3+ by Y3+ in magnetite (Fe3O4) on morphology and inorganic arsenic species adsorption efficiency of the Fe3−xYxO4 nanoparticles formed. The series of Fe3−xYxO4 (x=0.00, 0.042 and 0.084, labeled as Y00, Y05 and Y10, respectively) was synthesized using co-precipitation followed by microwave-hydrothermal treatment (MW) at 200°C. With increase of yttrium content(xvalue), both the morphological inhomogeneity of the samples and the fraction of spinel nanorods as compared to spinel pseudospherical particles increased.

A proposal for the landslide damage questionnaire in suburban areas
Landslides are one of the most often natural disasters that have an extensive impact on society including loss of life, destruction of infrastructure and properties, damage to land and loss of natural resources. Landslide losses can significantly vary and they depend on a variety of different criteria such as the size and type of landslide, lithological setting of terrain, the terrain slope gradient, the quality of materials used for construction, and the construction typology. Damage from landslides is usually ...Uroš Đurić, Biljana Abolmasov, Miloš S. Marjanović, Sanja Jocković, Miloš D. Marjanović.

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, ......
