Petrološke karakteristike dunavskog šljunka (Beograd – Zemun)
Miloš Mihajlović (2024)Dunavski šljunak u okolini Zemuna karakterističan je za obalne rečne naslage formirane dugotrajnim procesima erozije i transporta materijala koje reka Dunav nosi sa različitih područja uzvodno. Ispitivanja šljunka sa lokacije „Gemax” su pokazala je šljunak uglavnom zaobljen, najčešće u rasponu od nekoliko milimetara do nekoliko centimetara u prečniku. Kako Dunav nosi materijal sa velikog sliva, ovaj šljunak sadrži raznovrsne sastojke sa dominacijom kvarca i odlomaka stena visokosilicijskog sastava. Mineraloško-petrografska ispitivanja pokazala su prisustvo klasta različitog sastava, čime je potvrđena ...... sistemom, levak za sipanje uzorka spremljenog za ispitivanje u menzuru, šejker za cilindar, vaga.

Development and evaluation of fracture gradient curve model: a case study of south-central Kazakhstan
An accurate fracture gradient value is one of the most important issues in oil and gas well design and drilling. The value of a fracture gradient is a critical parameter for determining the drilling mud weight and selecting the proper depths for setting the casing in the planning process of drilling operations. This paper proposed the new curve model of fracture gradient for the south-central Kazakhstan (central Asia) region based on the analysis of leak-off test and format integrity ...Branimir Stanisavljevic, Vesna Karovic Maricic, Irena Isakov.

The Flow Conditions in the Epikarst Zone of a Karst Aquifer. Case Study: Suva planina Mt., East Serbia
Branislav Petrović (2023)The epikarst as a part of the karst aquifer represents a complex point of contact and mixing of unconsolidated material from the terrain surface, carbonate rocks altered by “corrosive” water, flora and fauna (and remains of), which is partially saturated with groundwater. Significant amounts of (plant accessible) water, and other solutes and particles, can be stored in this zone for extended periods of time. Thus, attenuation or biochemical processes could start in this layer and change quality of infiltrated ...Branislav Petrović. "The Flow Conditions in the Epikarst Zone of a Karst Aquifer.

Control of substructure construction of railways in the Republic of Serbia
Контрола збијености природног тла (у ископу) или збијеног у насипу при изградњи саобраћајница представља један од основних облика контроле квалитета доњег строја. Код изградње брзих саобраћајница (аутопутеви и брза железница) приоритет је постизање високог нивоа контроле извршених радова. У циљу онемогућавања диференцијалног слегања (при изградњи насипа), или промене запремине услед допунског збијања материјала, које неминовно доводе до деформација, потребно је извршити оптимално збијање материјала.

Damage quantification of built stone on Dark Gate (Belgrade, Serbia): sample of damage index application for decay rate evaluation
The Dark Gate is the monument of culture, part of the cultural and historical complex of the Belgrade Fortress. It is constructed of limestone blocks that after 270 years of exposure to environmental conditions and different anthropogenic influences show wide ranges of decay forms. During 2007, detail registration of all built limestone microfacies and weathering forms was done using tools of monument mapping. A correlation scheme ‘‘intensity– damage category’’ was made according to the type, intensity, and distribution of ...... stone was historically the predominant material used for building and artistic pur- poses.

Using gravity data to define structural correlation affecting the formation of Neogene basins
A gravity survey can help to define the structural correlation in the study area. The structures that have influenced the development of Neogene basins can be defined using gravity data. By applying mathematical transformations to gravity data, the geological structures (faults, nappes, etc.) that impacted the formation of Neogene basins can be defined. We have taken the part of the Dinarides as the test region.
