Numerical modeling of Selanac debris flow propagation using SPH code
The Selanac debris flow is a very huge event triggered after extreme rainfall caused by Cyclone Tamara activity in the Republic of Serbia in May 2014. The Selanac case study was already modelling in different programs using Voellmy rheology assumptions like RAMMS software. In this paper research are focusing particularly on the process of debris flowing from initiation zone to main deposition area using Geoflow SPH two-phase model considering frictional rheology law. Main rheological parameters are back-calculated using also ...... Figure 3 Final model of flow heights A) 16s B) 30s C) 50s D) 100s SCG-XIII INTERNATIONAL SYMPOSIUM ON LANDSLIDES.

Upper Miocene depositional environments of the Kikinda-Mokrin High (Serbia)
Saša Ivanišević, Dejan Radivojević (2018)Exploration for oil and gas in mature areas, such as the Pannonian Basin, can benefit from reexamination of old data using more advanced modern workflows that focus on the temporal and spatial aspects of sediment deposition. Specifically, we apply a new environment of deposition model that interprets the Upper Miocene- Pliocene sediments as being deposited in a rapidly filling basin characterized by quick shelf edge progradation from the northwest toward the southeast.

Testing the energy value of different types of coal by the method of active thermography
In this paper, coal thermograms are presented and analyzed in order to determine their energy value. Two types of coal of different categories, brown and lignite, were selected for active thermographic imaging. The tested coal samples were processed before measurement so that they are similar in dimensions and have two plane-parallel smooth surfaces. The test samples were "primarily" heated under the same conditions and the process of their cooling was monitored by a thermal camera. "Then" they were cooled ...Stevan Đenadić, Ljubiša Tomić, Vesna Damnjanović, Predrag Jovančić, Dragutin Jovković.

Application of the principle of circular economy to the thermal groundwater, the example of the municipality of Bogatić
There are about 360 locations of thermal and thermo-mineral waters in Serbia, whose water temperatures range from 14 to 98°C, which ranks Serbia as the richest European country in geothermal energy. The mentioned water resources (thermal and thermomineral waters) are used, mostly, for therapeutic purposes in spas and sports and recreational centers. The main problem that is present is the fact that they are not used in a rational and efficient way. The paper will give examples territorially related ...Marija Jovanović, Vesna Ristić Vakanjac.

The in vitro effect of Al3þ ions in the concentration range 1.7·1026M–8.7·1023M on pepsin activity at pH 2, via kinetic parameters and its electrophoretic mobility was evaluated. Kinetic study demonstrated the existence of an activation effect of Al3þ at pH 2 on pepsin molecule. Kinetic analysis with respect to concentrations of haemoglobin showed that Al3þ ions increase the maximal velocity (Vmax) and kcat values rather than apparent affinity for substrate (KS) implying the non-competitive nature of activation which indicated ...... bacteriophage.
