(Institute for Medicinal Plants Research "Dr. Josif Pancic", 2019)
The aim of the present study was the optimization of the extraction conditions (particle size, solid-to-solvent ratio, extraction time and procedure) via total polyphenol content and radical scavenging activity, using wild ...
Application of permeable materials for CBRN protective equipment / Primena filtrosorpcionih materijala za NHB zaštitnu opremu
(Engineering Society for Corrosion, Belgrade, Serbia, 2015)
The new concept of chemical, biological, radiological and nuclear combat clothing offers the opportunity of substantial cost savings by eliminating the need for additional, CBRN over garments, whose high weight and poor ...
Analysis of fracture behaviour of thin s316l stainless steel plates
(Institut za ispitivanje materijala, Beograd, 2017)
In this paper are presented experimental analyses of the behaviour of 316L stainless steel in regard to fracture, according to standard methods of investigation on modified tensile C(T) specimens. The S316L alloy is selected ...
Determination of the coffin-manson equation under low-cycle fatigue conditions
(Structural Integrity and Life-Integritet I Vek Konstrukcija, 2021)
The cycle loading of a material results in the modification of its properties and so in this paper is presented the behaviour of the fatigue life using low-cycle fatigue parameters. By applying the Coffin-Manson equation ...
