Karst wastewater as a high quality, renewable and within the circular economy water resource
Jovana Nikolić, Vesna Ristić Vakanjac (2021)High quality drinking water in it’s natural state is becoming less and less available to the human population. Based on the expected climate changes, it is considered that this resource will be less in the world but also in our region. Also, the accompanying polluting components that exceed the maximum allowable concentration are increasingly present in the waters. Even after the water treatment, it happens that some components are still in the drinking water, which adversely affects human health. ...Jovana Nikolić, Vesna Ristić Vakanjac.

Mogućnost korišćenјa toplotnih pumpi sa otpadnom toplotom iz postrojenјa za prečišćavanјe otpadnih voda kao toplotnim izvorom
U narednom periodu se planira izgradnja nekoliko desetina sistema za prečišćavanje otpadnih voda u većim gradovima u Srbiji. Iskustva iz postrojenja koja su trenutno u radu, pokazuju da bi prečišćena otpadna voda, s obzirom na protok i temperaturu, mogla da predstavlja značajan izvor obnovljive energije. U radu su prikazani primeri dobre prakse korišćenja ove energije u sistemima daljinskog grejanja u zemljama Evropske unije.

Потреба за израдом биланса и оценом расположивих резерви подземних вода Републике Србије
Природне карактеристике Србије, просторна дистрибуција ресурса водe и њихових корисника, као и међусобна интеракција коришћења, заштите вода, као и заштите од вода, условиле су да се подземне воде на читавој територији морају посматрати интегрално, јединствено, комплексно и рационално. Међутим, тренутно је у Републици Србији могуће дефинисати само одлике појединих издани и/или изворишта услед непостојања довољних података за свеобухватну анализу стања ресурса.

Productivity improvement with use of beam gas compressor: pilot test in Southeastern Europe mature field
Most of the wells in the oilfield Turija are operating with sucker rod pumps, where casing pressure at around 15 bar, and with marginal production rates. The high value of casing pressure indicates high pressure on the face of the formation and depends directly on well productivity. In addition, with increasing value of the casing pressure gas column in the annulus is moving the dynamic fluid level near pump intake and more gas is entering the pump, it results ...beam gas compressor, BGC, increase productivity, sucker rod pump, SRP, mature field, artificial lift, production optimisationBojan Martinović, Dušan Danilović, Branko Grubač, Robert Fadiga.

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.

Uticaj raspadanja na stabilnost kosina u mekoj stenskoj masi
Anđela Despotov (2024)U radu je opisano ponašanje mekih stenskih masa koje su izložene porecesu raspadanja tokom određenog vremenskog perioda. Meke stenske predstavljaju kritične vrste stenskih masa pošto izazivaju različite probleme tokom izvođenja građevinskih radova. Meke stene mogu biti sedimentne stene, raspadnute metamorfne i magmatske stene. Odlikuju se niskim vrednostima čvrstoće, visokom deformabilnošću, visokom plastičnošću, podložne su dezintegraciji i fizičko-hemijskom raspadanju, odnosno ubrzanom dejstvu površinskog raspadanja usled atmosferskih uticaja.Za klasifikaciju mekih stenskih masa koriste se modifikovane verzije već postojećih klasifikacionih sistema.

Complex geophysical survey on solving the problem of water loss in the karst terrain reservoir
Branislav Sretković, Dejan Vučković (2023)Geophysical surveys in karst terrain are always a specific challenge. Each of them requires a careful consideration of the problem, specific conditions on the ground, the selection of adequate methods applicable in that specific and unique karst area. But they should have one thing in common: a complex approach and looking at the problem from wider to narrower, with a gradual narrowing of the investigation area, increasing the spatial precision and resolution of the obtained data. On the example of ...Branislav Sretković, Dejan Vučković.
