Побољшање ефикасности одлучивања у рударству применом линеарних оптимизационих модела
Трајче Бошевски (2021)Одлучивање и управљање у рударству је захтеван и сложен задатак изложен ризицима. Конвенционални-искуствени приступи доношења одлука, у пракси често показују слабост која се огледа у недовољној поузданости и прецизности. Предмет истраживања докторске дисертације, под називом „Побољшање ефикасности одлучивања у рударству применом линеарних оптимизационих модела“ је да, сагледавањем научних метода линеарног програмирања, приступи формирању локацијских модела који би били засновани на анализи и прилагођавању постојећих и увођењу нових претпоставки за случајеве као што је експлоатација и потрошња кречњака.

Hydrochemical indicators of groundwater flow in the area of “Čukaru Peki” Cu-Au underground mine in eastern Serbia
The physical and chemical properties of groundwater, together with the groundwater levels regime and rock hydraulic properties, are often used to understand and conceptualize the hydrogeological system. Prediction of the influence of mining works on groundwater, and vice versa, is a challenge due to significantly altered groundwater flow patterns in the raw materials exploitation areas in relation to natural conditions. Therefore, multiple parameters are assessed and monitored before and during exploitation to properly characterize and quantify the system for ...Nebojša Atanacković, Vladimir Živanović, Jana Štrbački, Veselin Dragišić, Ivana Cvejić.

Distribution of Potentially Toxic Elements in the City of Zintan and Its Surroundings (Northwestern Libya) by Surface Soil Sampling
Boris Vakanjac, Zorana Naunović, Vesna Ristić Vakanjac, Tanita Đumić, Saša Bakrač, Jana Štrbački, Vuk Gajić, Taher Mohamed Alzarog (2023)The study area is the city of Zintan, in northwestern Libya, which has grown over the past 30 years. Its current population is roughly 30,000. Although the city is in part commercial, most of the population engages in agriculture and primarily grows cereal crops (wheat and barley). The demand of the growing city for agricultural products has increased, intensifying the use of fertilizers, pesticides, and insecticides. Consequently, concentrations of potentially toxic elements (PTE) in the soil have increased.

Burnishing Versus Smoothing In Ceramic Surface Finishing: A Sem Study
From the Neolithic up to the present, people have used various methods to improve the surface of ceramic objects. In this study, we look specifically at smoothing and pattern burnishing of ceramics produced today by traditional methods. Optical microscopy and SEM show specific surface changes. Smoothing results in an irregular surface, which causes diffused reflection of light. Burnishing produces an even and compact surface, which causes specular reflection and lustre. The results can be used to infer methods of ...Ionescu Corina, Volker Hoeck, Crandell Otis N., Šarić Kristina.

Geostatički proračuni sanacije klizišta šipovima
U ovom radu su, polazeći od rezultata geotehničkih istraživanja, prikazani geostatički proračuni sanacije klizišta vertikalnim šipovima. Metodologija proračuna je složena, jer podrazumeva interakciju klizišta i stabilizirajućih šipova. Stoga se simultano analiziraju stabilnost klizišta i stabilnost šipova. Prilikom određivanja bočne otpornosti tla oko šipova koristi se metoda Brinč Hansena koja uzima u obzir trodimenzionalne uslove u tlu i može da se primeni u složenim geološkim uslovima koji su česti u Srbiji.
