Replica of the “Great Triangle Gold Nugget” Belonging to Belgrade University Collection, Gilded or Not?
... Belgrade in Serbia, has been holding over a hundred years the gypsum model of triangular shape that represents the replica of one of the world’s largest native gold nugget weighing 36.2 kg, known as “The Great Triangle”. Nugget model is golden metallic in colour with a shape similar to a rectangular ...
... Since the gold colour and shine remained the same, did not darken by the time it was assumed that the model is gilded. Material and method Chemical composition of the gypsum model surface was carried out in the Laboratory for SEM, Faculty of Mining and Geology, University of Belgrade ...
... the type and manner of material that was used for covering. Result and conclusion The data obtained by EDS analysis show that the gypsum model is covered with gold leaf, which was expected according to the macroscopic characteristic of the object. How many such gilded replicas of the ...Alena Zdravković, Maja Milošević, Ivana Jelić.

Geotehnički aspekti izgradnje visećeg pešačkog mosta u Starom gradu u Užicu
U radu su prikazani rezultati geotehničkih istraživanja za potrebe izgradnje visećeg pešačkog mosta preko klisure reke Đetinje u Užicu. Predviđeno je da most, sistema prednapregnute trake, omogući prelaz pešacima sa desne dolinske strane na stranu Starog grada, koja je opasana strmom liticom (cca. 40 m visine). Za potrebe formiranja geotehničkog modela i strukturnog sklopa krečnjačke stenske mase korišćen je postupak fotogrametrijskog snimanja dronom. Predviđeno je da se zatežuća sila (od oko 30 MN), koju most prenosi na obalni stub, ...fotogrametrija, stabilnost kosina, pukotine, prednapregnuta sidra, test granične nosivosti, paker (Ližonov) test... napravljen je numerički model stenske mase i izvršeni su proračuni stabilnosti metodama granične ravnoteže i konačnih elemenata. Na ovaj način određen je faktor sigurnosti, kao i pomeranja konstrukcije. 2. GEOLOŠKA GRAĐA I ISTRAŽIVANJA TERENA 2.1. Strukturno-geološke karakteristike terena u zoni ...
