GEOSPATIAL MAPPING OF ECOLOGICAL RISK FROM POTENTIALLY TOXIC ELEMENTS IN SOIL IN THE PANNONIAN-CARPATHIAN BORDER AREA SOUTH OF THE DANUBE
(Carpathian Association of Environment and Earth Sciences, 2022)
This study collected agricultural surface soil samples from 200 sites in the district of Braničevo, located in the Carpathian Mountains – Pannonian Basin south of the Danube River (Serbia). The main objective was to determine ...
Influence of periodate oxidation on sorption properties of viscose yarn
(Editura Acad Romane, Bucuresti, 2018)
Viscose yarn was submitted to oxidation using different sodium periodate concentrations for various periods of time in order to investigate the influence of oxidation on the chemical and sorption properties of the resulting ...
Crack propagation in 3PB specimen made from welded joint
(1st Virtual European Conference on Fracture - Vecf1, 2020)
Crack propagation in 3PB specimen has been investigated experimentally by using Digital Image Correlation (DIC) technique. For this purpose, specimens were taken from butt welded plates, made of P460NL1 micro-alloyed steel. ...
New functional polymers obtained by amination of PVC
(Proceedings of the fourth Yugoslav Materials Research Society Conference (YUCOMAT IV), 2002)
A new procedure for introduction of aromatic diamines into polymer, in particular into poly(vinyl chloride) (PVC) molecule, was developed. Produced materials have attractive properties such as combination of good film-forming, ...
