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 ...
Quality assurance of storage tanks after in-service crack repairs / Osiguranje kvaliteta rezervoara u eksploataciji posle popravke prslina
(Society for Structural Integrity and Life, Institute for Material Testing, 2013)
According to the Pressure Equipment Directive (PED 97/23/EC) a new produced storage tank can be accepted on the market only if the required quality is proved. In this way the structural integrity might be at the requested ...
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 ...
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 ...
Modeling of the matrix porosity influence on the elastic properties of particulate biocomposites / Modeliranje uticaja matrične poroznosti na elastične osobine poroznih biokompozita
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, 2012)
For a wide range of engineering structures such as ceramics, porous shape memory alloys, foam-like structures and thermal spray deposits, porous materials have been used. Recently, porous biocomposites for the applications ...
Antimicrobial potential of triticale stillage after lactic acid fermentation with Lactobacillus fermentum PL-1 / Antimikrobni potencijal džibre tritikalea posle mlečno-kisele fermentacije pomoću Lactobacillus fermentum PL-1
(Faculty of Technology, Novi Sad, 2013)
This study is concerned with the testing of antimicrobial activity of triticale stillage obtained after lactic fermentation by Lactobacillus fermentum PL-1. The antimicrobial tests were performed using the disc-diffusion ...
Intellectual property and regulation of functional foods
(Economics institute, Belgrade, 2012)
Today, there exist scientific evidences that functional foods have favorable physiological and psychological effects as well as additional functions in relation to health, apart from the basic nutritional effects, thus ...
Preparation of glass-ceramic in Li2O-Al2O3-GeO2-P2O5 system
(University of Novi Sad, 2013)
The results of preparation and structural characterization of glass-ceramics from the system Li2O-Al2O3-GeO2-P2O5 are shown in this paper. The crystallization behaviour of the selected glass was examined under non-isothermal ...
