Efficiencies of different methods for determination of organophosphate pesticide residues in fermented wheat substrate / Efikasnost različitih metoda za određivanje ostataka organofosfata u fermentisanim uzorcima žita
(Institute of Pesticides and Environmental Protection, 2013)
In the present work, the efficiencies of three different sample preparation methods for GC/ MS determination of pirimiphos-methyl and chlorpyrifos-methyl residues in wheat (Triticum spelta) samples fermented by Lactobacillus ...
Finite element analysis of fracture resistance parameters for stationary semi-elliptical surface cracks in high strength steel / Analiza parametara otpornosti na lom metodom konačnih elemenata, kod stacionarnih polueliptičnih prslina u čeliku povišene čvrstoće
(Society for Structural Integrity and Life, Institute for Material Testing, 2015)
This study deals with numerical simulations based on elastic-plastic finite element method for nonlinear stress analyses on pre-cracked tensile specimens with high strength properties. The influence of crack geometry on ...
Determination of activation energy for static recrystallization using multipass continuous cooling torsion test
(Savez inženjera metalurgije Srbije, Beograd, 2009)
Two microalloyed steels (Nb low carbon and V medium carbon) were tested by means of multistage continuous cooling torsion with aim to evaluate the interpass recrystallization data, by means of Tnr (temperature of ...
Application of exergy analysis in recycling streams / Primena eksergijske analize u reciklažnim tokovima
(Engineering Society for Corrosion, Belgrade, Serbia, 2015)
Materials for recycling always contain a certain degree of contamination. The presence of impurities i.e. contamination in the recycling streams causes a change in the composition of the original materials to recycle. As ...
Examination of wear resistance of polymer-basalt composites
(Univerzitet u Kragujevcu - Fakultet inženjerskih nauka, Kragujevac, 2013)
Olivine basalt, as a natural material, has excellent physical and mechanical properties such as hardness, compressive strength, wear resistance, color and gloss. On the other hand it is difficult for processing, because ...
Assessment of pressure vessel load capacity in the presence of cracks / Procena nosivosti posude pod pritiskom u prisustvu prsline
(Society for Structural Integrity and Life, Institute for Material Testing, 2013)
The paper illustrates the structural assessment of an investigated pressure vessel, made of low-alloyed high strength steel, with an external surface crack located on the shell wall. In order to assess the remaining strength ...
Tension mechanical properties of recycled glass-epoxy composite material / Mehanička svojstava recikliranog staklo-epoksi kompozitnog materijala
(Faculty of Technology, Novi Sad, 2012)
The significance of composite materials and their applications are mainly due to their good properties. This imposes the need for their recycling, thus extending their lifetime. Once used composite material will be disposed ...
Procedures for processing of copper secondary raw materials / Postupci prerade sekundarnih sirovina bakra
(Engineering Society for Corrosion, Belgrade, Serbia, 2013)
The technological procedures for copper secondary raw materials processing include two basic stages: pretreatment of the copper waste and its further metallurgical processing. For copper waste pretreatment technology, there ...
