Irradiation resistance of elastomeric composites based on NR/CSM blend and waste rubber powder
(RAD Centre, Niš, Serbia, 2021-06-14)
Effect of waste rubber particles (WTR) size on elastomers based on natural rubber and chlorosulfonated polyethylene rubber (NR/CSM= 50:50) was studied. Two types of WTR with different particle size (150–250 μm and 450–600μm) ...
Applications of conductive polymers in modern technologies
(University PIM, Banja Luka, Republic of Srpska, B&H, 2022-06-02)
Polymers are the subject of intensive research and development, not only in science but also in industry. In the last few years, many studies have been conducted on conjugated polymers, and this study of polymers has ...
A Sensitive Voltammetric Sensor for Caffeic Acid Made from Thermolised Modified UF Resins With Incorporated Fe(III) and Ti(IV) Oxide Particles
(University of Novi Sad, Faculty of Technology Novi Sad, 2022-10-20)
Domestic high performance electrode material was prepared by thermolysis of in situ synthesized urea-formaldehyde (UF) resins modified with Fe(III) nitrate and Ti(IV) oxide in different combinations: iron salt and UF resins ...
INFLUENCE OF MODIFIED MONTMORILLONITES ON FORMALDEHYDE CONTENT IN UREA-FORMALDEHYDE/MONTMORILLONITE COMPOSITES
(University of Novi Sad, Faculty of Technology Novi Sad, 2022-10-20)
The effect of different montmorillonites (KSF and K10) and their modifications (Na-KSF, Na-K10) on content of formaldehyde-FA (free and liberated) modified urea-formaldehyde (UF) composites was investigated. KSF and K10 ...
Radon anomalies as precursors of a recent earthquake: A case study of Kosovska Mitrovica environment
Spike-like peaks in the concentration of radon gas prior to a major earthquake are attributed to release different gases (CO2, CH4, H2S, SO2, H2 suitable for the transport of radon to the earth’s surface) due to pre-seismic ...
Annual effective dose due to ingestion and inhalation of radon in water samples from public fountains in municipality of Kuršumlija, Serbia
In the present study, the water samples were taken from public fountains in rural area
municipality of Kuršumlija, in southern part of Serbia. Sampling of water from public fountains began subsequently according to ...
Relationship between outdoor radon concentrations and meteorological parameters
In order to establish radon levels in outdoor atmosphere radon measurements were performed during the fifteen days by alpha spectrometric measuring method with detector Airthings Corentium Home. Measuring point was at 0.5 ...
High indoor radon concentration in residential houses. Ninth International Conference on radiation and applications in various fields of research, RAD9, Virtual Conference, Herceg Novi, Montenegro, July 14-18, 2021.
People are mainly exposed to radon in indoor environments. Exposure to radon and its decay products is the second leading cause of lung cancer, and there is a strong synergistic effect with smoking. The most significant ...
Small deformations, variations and energies of curves
Contrary to isometries as transformations that preserve distances, in-
finitesimal bending is a type of small deformation in which the arc length
is invariant with appropriate precision. The influence that given ...
