Heavy metals in petroleum-contaminated surface soils in Serbia
(Societa Chimica Italiana, 2004)
Investigation of heavy metal contamination levels as well as their association types with substrates in petroleum-contaminated surface soil was carried out using modified sequential extraction method. In that way, ...
Impact of wind speed on the concentration of PM2.5 in ambient air
(Belgrade : Vinča Institute of Nuclear Sciences, 2016)
Twenty-four hour measurements of PM2.5 particulate matter have been carried out during the period between the 22nd January
and the 25th February 2013 in a suburban area of Belgrade. PM2.5 samples were collected on 47 mm ...
ANTIOXIDANT AND ANTIMICROBIAL EDIBLE FILMS BASED ON DEXTRAN CONTAINING POLYPHENOLS FROM YARROW EXTRACT
(Polychar 26 World Forum on Advanced Materials, 2018)
Current trends in food biotechnology are focused on replacing synthetic polymers used for food packages by the natural ones. Biopolymers are made by sustainable processes in a cheap way. Moreover, they are nontoxic and can ...

The subject of this paper is the structural design of a safety steel device that is located between the standard wagon buffer and the collision energy absorber. The safety steel device is a sacrifical part able to withstand ...
Numerical analysis of fracture of non-standard ring specimen for examination of axially flawed cylindrical structures
(14th International Conference on Fracture, ICF 2017, 2017)
Integrity of cylindrical structures, such as pipes and small-scale pressure vessels, is typically assessed by testing fracture mechanics specimens, like compact tensile CT or single-edge notched bending, SENB. However, ...
Ductile crack growth initiation in welded joints - Micromechanical approach
(Welding in the World, 2008)
The integrity of welded structures depends on the load-carrying capacities of their welded joints. Having in mind that welding process produces a large microstructural gradient through the weld, resulting in variation of ...
