A contribution to the understanding of the discharge dynamics and water balance of the karst spring Gornji Dušnik (Suva Planina)
A sufficiently long time-series of daily discharges is needed to assess the discharge dynamics and calculate the water balance equation parameters of a spring (river source). The paper assumes that a catchment is gauged if a time-series of observations of at least 30 years is available, which is a rare case in Serbia. One-year monitoring is often set up to verify the reserves of a water source or spring intended for capture. Monitoring ceases after the final report is ...Aleksandar Tanasković, Vesna Ristić Vakanjac, Dušan Polomčić, Jelena Ratković.

Turbidity simulation for short-term prediction: case study of the karst spring Surdup (Bor, Serbia)
Из перспективе снабдевања пијаћом водом, квалитет воде карстних издани је међу највишим, и често захтева само њихову дезинфекцију пре употребе. Међутим, карстне подземне воде изложене су одређеним притисцима. Током сушних периода углавном има мало воде, а током кишних периода има изненадних променa и квалитета и количине воде. Реакција слива на падавине је често брза и варијације у параметрима квалитета и квантитета (истицање, ниво вода, замућеност, укупан број микроорганизама, суспендовани нанос, итд.) су нестабилни. Ово захтева праћење истицања и ...Marina Pešić, Vesna Ristić Vakanjac, Boris Vakanjac, Kostadin Jovanov.

Method validation and geochemical modelling of chromium speciation in natural waters
The study focuses on validating reference methods such as ICP-OES and ICP-MS for detecting ultratrace levels of chromium in groundwater, where concentrations are typically very low. Additionally, it verifies a hyphenated technique, IC-ICP-MS, for determining naturally occurring Cr(VI) in tested waters. The validation process involved various chromium analysis variants, including isotopes 52Cr and 53Cr in ICP-MS and IC-ICP-MS techniques, along with specific emission lines in the ICPOES technique. Statistical data processing revealed that the achieved limits of quantification for ...шестовалентни хром, ИЦ-ИЦП-МС, технике са цртицама, геохемијско моделирање, анализа спецификација, валидација методеPiotr Rusiniak, Katarzyna Wątor, Ewa Kmiecik, Vesna Ristić Vakanjac.

Influence of DEM resolution on numerical modelling of debris flows in RAMMS - Selanac case study
Debris flows induced by intensive rainfall represent very hazardous phenomena in many parts of the World. Methods for prediction of runout distance of flow like mass movements are different and depending on the input data, rheology, and available or appropriate numerical solution. However, sometimes it is not easy to obtain pre event and post event high-resolution data in the rural or mountainous area. Thus, the topology of terrain is the most important input parameter for the every real case ...Jelka Krušić, Biljana Abolmasov, Mileva Samardžić Petrović.

Microstructural and magnetic properties of electrospun hematite/cuprospinel composites
Phase composition, microstructural and magnetic properties of electrospun hematite/cuprospinel composites were investigated. Samples were synthesized starting with 0 to 10 mol% of copper relative to iron. The round shape of reference electrospun fbres was preserved upon their heating up to 600 °C in air, whereas at 700 °C hollow substructure was additionally formed. In these reference samples the presence of hematite phase was detected by XRPD. A small amount (traces) of Fe3O4 /γ-Fe2O3 was also found, due to the ...Electrical and Electronic Engineering, Condensed Matter Physics, Atomic and Molecular Physics and Optics, Electronic, Optical and Magnetic MaterialsMira Ristić, Aleksandar Kremenović, Michael Reissner, Željka Petrović, Svetozar Musić.

Primena modela transporta idealne čestice na primeru razvoja Površinskog kopa Jakovačka Kumša
Hidrodinamičkim proračunima transporta „idealne“ čestice prikazan je uticaj eksploatacije peskova sa površinskog kopa „Jakovačka Kumša“ na beogradsko izvorište podzemnih voda. Potencijalnu opasnost od zagađenja podzemnih voda izvorišta za vodosnabdevanje čini skup različitih procesa koji se odvijaju na površinskom kopu. U radu je prikazano poređenje dva modela transporta idealne čestice. Prvi model se odnosi na analizu putanje i vremena putovanja idealne čestice od površinskog kopa do izvorišta za stanje pre otvaranja kopa, dok se drugi model odnosi na stanje kada ...upravljnje podzemnim vodama, zaštita podzemnih voda, hidrodinamički model, metoda praćenja „idealne“ čestice, modflow, modpathDušan Polomčić, Dragoljub Bajić, Vesna Ristić Vakanjac, Marina Čokorilo Ilić.
