Analiza hidrauličke veze između reke Save i podzemnih voda na izvorištu za vodosnabdevanje Obrenovca
Na izvorištu „Vić bare“ formiranom u aluvijonu Save za vodosnabdevanje Obrenovca u poslednje dve decenije izvedeno je više detaljnih hidrogeoloških istraživanja u cilju utvrđivanja rezervi podzemnih voda i izdvajanja zona sanintarne zaštite. Monitoring podzemnih voda u celoj zoni izvorišta, za potrebe izrade hidrodinamičkog modela, omogućio je i hidrauličku analizu odnosa površinskih voda reke Save i podzemnih voda na izvorištu sa kojeg se trenutno zahvata do 310 l/s vode. U radu su prikazani rezultati korelacione analize, odnosno ispitivanja na ...Dragoljub Bajić, Bojan Hajdin, Dušan Polomčić, Vesna Ristić Vakanjac.

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.

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.
