Climate change and their imapct on karst groundwater
Milan Đelić, Vesna Ristić Vakanjac (2021)In the last 30 years, there have been progressively more dry and rainy years, a reduced presence or even absence of snow cover, an increase in air temperature, large-scale fires, intensified glacier melting, and the like. Climate change certainly has an effect on all areas of economic activity, but its largest impact is on water resources and existing ecosystems. One of the most important water resources is groundwater, on account of which more than 70% of the population of ...Milan Đelić, Vesna Ristić Vakanjac .

Manganese-pyromellitate complex as a precursor for preparation of spinel Mn3O4
Lidija Radovanović, Željko Radovanović, Aleksandar Kremenović, Bojana Simović, Milica V. Vasić, Jelena Rogan (2022)In recent years, thermal decomposition studies of transition metal complexes with benzenepolycarboxylate ligands have become an area of a great importance due to the possibility of obtaining useful metal oxides with desirable electrical, magnetic and catalytic properties [1]. As a contrast to conventional methods for the preparation of metal oxides, such as hydrothermal or sol–gel treatment, thermolysis is faster, more efficient ...Lidija Radovanović, Željko Radovanović, Aleksandar Kremenović, Bojana Simović, Milica V.

The number of nonunimodular roots of a reciprocal polynomial
Dragan Stankov (2023)We introduce a sequence Pd of monic reciprocal polynomials with integer coefficients having the central coefficients fixed as well as the peripheral coefficients. We prove that the ratio of the number of nonunimodular roots of Pd to its degree d has a limit L when d tends to infinity. We show that if the coefficients of a polynomial can be arbitrarily large in modulus then L can be arbitrarily close to 0. It seems reasonable to believe that if ...Algebraic integer, the house of algebraic integer, maximal modulus, reciprocal polynomial, primitive polynomial, Schinzel-Zassenhaus conjecture, Mahler measure, method of least squares, cyclotomic polynomialsDragan Stankov.

The impact of temporal variability of groundwater levels on groundwater vulnerability maps in karst terrains – a case example of the Perućac spring catchment area
Groundwater vulnerability maps represent an essential tool for protecting karst groundwater resources. Vulnerability assessment is usually based on spatial evaluation of various parameters that affect the vulnerability degree and regulate the protection role of the unsaturated zone. Most of these parameters, like soil and geology conditions, are constant and do not change during the year or over several years. In contrast, some parameters, such as the groundwater level, depend on the variability of recharge conditions. By considering the variability ...Vladimir Živanović, Igor Jemcov, Nebojša Atanacković.

Upper Cretaceous scaglia type limestone from Klepa Mts. (North Macedonia) - sedimentology and biostratigraphy
The research area is located in the central part of North Macedonia, in the area of the Klepa Mts. Based on sedimentological, micropaleontological and biostratigraphical investigations of samples from both the east and west side of the Klepa Mts., sedimentary rocks of the Upper Creaceous age are determined. During the latest Cretaceous, this area was dominated by the sedimentation of dominantly carbonate rocks with variable amounts of clastic components. From the tectonic point of view, investigated area belongs to the ...Violeta Gajić, Milena Dunčić, Ana Mladenović, Dejan Prelević. "Upper Cretaceous scaglia type limestone from Klepa Mts.

Possibilities for Reduction of Energy-Related Air Pollution in Serbia - Exploring Energy Scenarios
Fossil fuels and biomass account for almost 93% of the total primary energy supply in Serbia. Meeting the energy needs of consumers implies a transformation of the chemical energy of fuels through combustion processes to obtain heat that can be utilized as such, or further transformed into mechanical or electrical energy. These processes have an undeniable impact on air pollution, even in cases of biofuels or hydrogen combustion. Possibilities for air pollution reduction are identified, both on the supply ...Marija Živković, Boban Pavlović, Dejan Ivezić, Aleksandar Mijatović.

Dynamic and Static Elastic Properties - Laboratory Investigations of Metamorphites of the "Vranjska Banja" Series
Metamorphites of the series “Vranjska banja” built predominantly of high crystallinity schist series, alternately layered double mica, gneiss, leptonite and micaschist. For the construction of the “Prvonek” dam were carried out laboratory investigations of dynamic and static elastic properties on micashist and gneiss samples in the perpendicular and parallel direction to the foliation. These investigations provided monitoring of the rock mass anisotropy properties and greater reliability of the design parameteres. As the design of mining and construction facilities becomes ...Jelena Majstorović, Bojan Dimitrijević, Suzana Lutovac, Snežana Savković, Miloš Gligorić.
