Hidrogeohemijska valorizacija esencijalnih mikroelemenata mineralnih voda Srbije
Jana S. Stojković (2013-09-25)Mineralne vode još od davnina privlače pažnju ljudi i to kako u pogledu istraživanja iproučavanja, tako i u pogledu njihovog iskorišćavanja. Naročito je važno poznavanjesadržaja mikroelemenata u njima, jer su to komponente njihovog hemijskog sastavakoje ih odvajaju od tzv. „običnih“ malomineralizovanih voda.U ovom radu proučavani su odabrani esencijalni mikroelementi (fluor, bor, litijum,kalijum, stroncijum i silicijum), u mineralnim vodama Srbije, pri čemu je analiziranopreko 130 uzoraka mineralnih voda iz različitih geoloških sredina, to jest hidrogeološkihrejona. Cilj ovog istraživanja bio je ...esencijalni mikroelementi, faktori migracije, zakonomernosti rasprostranjenja, hidrogeohemijski procesi, multivarijantna statistička analiza, mineralne vode Srbije...

Analiza primene višekriterijumskih metoda u optimizaciji izbora hidruličnih bagera na površinskim kopovima uglja
Hidraulični bageri primenjuju se u različitim oblastima privrede a najzastupljeniji su u građevinarstvu i rudarstvu. Na površinskim kopovima sa kontinualnim sistemima, klasifikuju kao pomoćna mehanizacija a na površinskim kopovima sa diskontinualnim sistemima, kao osnovna mehanizacija. Kako je u oba slučaja njihova primena neizostavna, važno je izvršiti adekvatnu analizu postojećih podataka, u cilju optimizacije izbora tipa hidrauličnog bagera u odnosu na uslove rada datog površinskog kopa. U radu su opisane različite višekriterijumske metode koje su korišćene za analizu hidrauličnih bagera. ...... kriterijuma.

Karst aquifer impact on the formation of surface runoff: case study of the Resava River catchment, Serbia
Marina Mitrašinović, Vesna Ristić Vakanjac, Veljko Marinović, Saša Milanović, Ljiljana Vasić, Dušan Polomčić (2022)The paper compares the flow regimes of the Resava River at the gauging stations of the Manasija Monastery (upper course) and the town of Svilajnac (lower course). The hydrological analysis encompasses a multiyear period of monitoring (1982–2020). The water budget and baseflow index are assessed for the catchment areas monitored by the Svilajnac station (683 km2) and the Manasija Monastery station (358k m2), considering the overall monitoring period and characteristic years. The results indicate that the specific runoff in ......

Određivanje parametara smičuće čvrstoće tla primenom statističke metode
Božidar Rudnjanin (2024)Određivanje parametara smičuće čvrstoće tla je od ključne važnosti u geotehničkom inženjerstvu jer utiče na stabilnost i nosivost raznih građevinskih konstrukcija. Ovaj master rad obrađuje temu primene deskriptivne statistike za analizu parametara smičuće čvrstoće tla,čime se obezbeđuje osnov za donošenje odluka o planiranju i izvođenju građevinskih projekata.U prvom delu rada, prikupljaju se relevantni podaci o smičućoj čvrstoći tla iz prethodnih laboratorijskih ispitivanja za trasu buduće brze saobraćajnice Novi Sad - Ruma.Ti podaci uključuju vrednosti smičuće čvrstoće i različite faktore ...... filtracije ž s Š JIE |3 š 3 ||-}E s |ž 3|8|5 s 5Š ž 8 š s| [} -| s| Š - Š |a B •| e Š |s žš žl f | g s ON |||sJ| svl e al šlžB}bS|Š|a|} „ „ šš |ž š H Š i F Fj E|ElE|Š '3 s Hi d Hi Š i ri }i :| xž |s *|: S . = = 3) 3 š i Š5|Q8|s|S|E|šIš|es|š|B5|" || | 3 |šš|ag| Zž ŠslŽ |č|e|šssS}| | a Fa s š Š a 2als ...

Late and post-collisional tectonic evolution of the Adria-Europe suture in the Vardar Zone
The Vardar Zone is a product of the Triassic-Jurassic opening of the Neotethys, Jurassic obduction, Late Cretaceous/Paleogene consumption of the oceanic crust and continental collision. During the last process, the Eastern Vardar Zone was thrust over the Central and eventually both onto the Western Vardar Zone. The present paleomagnetic and structural study provided new results from the first two zones in the Belgrade area. The younger set of data, together with published ones from the third zone, provide firm ...Emő Márton, Marinko Toljić, Vesna Cvetkov.
