Double traveling valve increases rod-pump efficiency
Traditional sucker rod pumps (SRP) use a single traveling valve, but recent double traveling valve innovations have improved SRP performance and efficiency in field applications with double traveling valves installed in pumps with top mechanical seating. The valves sealed better and produced similar fluid volumes compared with the previous single-valve pumps. They also enabled a reduction in pump diameter and optimized usage of surface equipment. Overall, the double travel valve SRPs produced stable production rates and annual production targets.Miloš Petrović, Bojan Martinović, Milica Ješić, Miroslav Crnogorac.

Razvoj integralnog modela za optimizaciju diskontinualnog sistema proizvodnje na površinskim kopovima nemetala
Miodrag Čelebić (2024)Izbor optimalne mehanizacije u diskontinualnom sistemu transporta je jedna od najvažnijih odluka koju treba donijeti prilikom projektovanja površinskih kopova. Pri izboru optimalne mehanizacije, uticaj ima veliki broj faktora, kako prirodnih – geoloških i ekoloških, tako i tehničkih, ekonomskih i socijanih. Neki od njih se mogu izraziti numerički, u određenim mijernim jedinicama, a neki opisno, lingvističkim varijablama, shodno uslovima koji vladaju na rudnim ležištima, a koje karakterišu visok stepen neizvjesnosti i neodređenosti kako prilikom istraživanja, tako i tokom procesa eksploatacije ...izbor mehanizacije, tehnologija eksploatacije, diskontinualani sistem, ekspertsko odlučivanje, lingvističke varijable, MCDM, FAHPMiodrag Čelebić.

Compaction of Municipal Solid Waste
Jovana Janković Pantic, Dragoslav Rakić, Tina Đurić, Irena Basarić Ikodinović, Snežana Bogdanović (2022)Regardless of the numerous activities undertaken to reduce municipal solid waste, its annual volumes continue to grow. In Serbia, the most common and the only one form of waste disposal is at municipal landfills with daily compaction and soil covering. Municipal waste compacting is one of the basic components of the disposal process. Well compacted waste takes up less volume and allows much safer storage. In order to better predict the behavior of municipal waste at landfills, it is ...Jovana Janković Pantic, Dragoslav Rakić, Tina Đurić, Irena Basarić Ikodinović, Snežana Bogdanović.

Challenges in using wastewater heat pumps in district heating systems
Dejan Ivezić, Marija Živković, Aleksandar Madžarević, Boban Pavlović, Dušan Danilović, Dimitrije Manić (2022)Decarbonization of district heating systems requires ensuring significant amounts of renewable energy available in the proximity of the district heating network. One of the promising solutions is the utilization of purified water from wastewater treatment plants by heat pumps. However, as a heat source, wastewater treatment plants are characterized by annual variability of the flow and temperature of purified water. The consequence is the variability of recoverable heat potential. In this paper, the effect of variability is analyzed for ...Dejan Ivezić, Marija Živković, Aleksandar Madžarević, Boban Pavlović, Dušan Danilović, Dimitrije Manić.

A proposal for the landslide damage questionnaire in suburban areas
Landslides are one of the most often natural disasters that have an extensive impact on society including loss of life, destruction of infrastructure and properties, damage to land and loss of natural resources. Landslide losses can significantly vary and they depend on a variety of different criteria such as the size and type of landslide, lithological setting of terrain, the terrain slope gradient, the quality of materials used for construction, and the construction typology. Damage from landslides is usually ...Uroš Đurić, Biljana Abolmasov, Miloš S. Marjanović, Sanja Jocković, Miloš D. Marjanović.

Strategic Environmental Assessment and the precautionary principle in the spatial planning of wind farms – European experience in Serbia
Spatial determination planning is at an initial and very sensitive step in the development of wind farms. On one hand, it is important to maximize the potential of wind in a particular area, and on the other hand, it is important to achieve environmental protection (including the human population and natural heritage) in the same space at the same time. With this in mind, it is important to balance all the requirements that are relevant for reaching the optimal ...Boško Josimović, Aleksandar Cvjetić, Danilo Furundžić.
