Influence of encastering on thin-walled cantilever beams with u and z profiles on the magnitude of equivalent stress and deformation
(Society for Structural Integrity and Life, Institute for Material Testing, 2019)
The purpose of this work is to present analytical and numerical determination of equivalent stress and deformation of open section thin-walled U and Z cantilever beams loaded with torsion. This work can be divided into two ...
The effect of calcinated hydroxyapatite and magnesium doped hydroxyapatite as fillers on the mechanical properties of a model bisgma/tegdma dental composite initially and after aging
(Savez inženjera metalurgije Srbije, Beograd, 2018)
This study aimed to investigate the possibility of modifying model BisGMA/TEGDMA dental composite by substituting 10 wt. % of conventional glass fillers with bioactive fillers based on calcinated nanosized hydroxyapatite ...
Bisphenol a removal from aqueous solution using fine alpha-fe2o3 particles
(Savez inženjera metalurgije Srbije, Beograd, 2018)
Iron(III) oxide particles (alpha-Fe2O3) were obtained from ferrous chloride (FeCl3 center dot 6H(2)O) precursor using ammonium hydroxide as a precipitating agent and particles were calcined at 700 degrees C for 4 h. ...
Modelling of Dyeing of Modified Polyester at Lower Temperature by Ultrasound
(University of Ljubljani, Fac Natural Sci & Engineering, Dept Textiles, Ljubljana, 2018)
This article discusses the process of polyester dyeing through the modelling process, i.e. the ability of adsorption of dyes for chemically modified polyester fibres of knitted fabrics in aqueous environment in the presence ...
Optimization of galacto-oligosacharides synthesis using response surface methodology / Optimizacija sinteze galakto-oligosaharida pomoću metoda odzivnih površina
(Institute for Food Technology, Novi Sad, 2017)
Galacto-oligosaccharides (GOS) are important lactose-derived compounds, considered to be a prebiotics, based on abundant scientific evidence about their unique physical properties and physiological effects. This consequently ...
The recycling of high magnesium aluminum alloys estimation of the most reliable procedure
(Savez inženjera metalurgije Srbije, Beograd, 2009)
Aluminum is one of the most recyclable materials. Namely, the properties of aluminum are not affected by the recycling and reuse, thus enable that high value of the metal is maintained after reprocessing. The re-smelting ...
Strain field measurements of glass ionomer cement
(Institut za ispitivanje materijala, Beograd, 2019)
Extensive evolution of glass ionomer cements (GIC) has marked a significant shift in the practice of luting indirect dental restorations limiting the use of zinc-phosphate and zinc-polycarboxylate cements to a few indications. ...
Influence of the polymer matrix type on cavitation resistance of composites
(University of Novi Sad, Faculty of Technical Sciences, 2021)
Cavitation resistance of polymer matrix / basalt powder composites was determined in this work. Two types of composites
were tested: epoxy resin / basalt powder composite and polyester resin / basalt powder composite. In ...
TRANSIENT TEMPERATURE FIELDS EFFECTS ON MULTI-PASS WELDING IN A BUTT JOINT OF AUSTENITIC PIPING / UTICAJI PRELAZNIH TEMPERATURSKIH POLJA NA VIŠEPROLAZNO ZAVARIVANJE U SUČEONOM SPOJU AUSTENITNIH CEVI
(Society for Structural Integrity and Life (DIVK), 2023)
This work uses computational thermomechanical model-based finite element analysis (FEA) to explore the effects of welding sequences on residual stresses that accumulate in the material and distortions of welded components, ...
Exploitation properties of ni-pd/al2o3 catalyst supported on ceramic foam
(Savez inženjera metalurgije Srbije, Beograd, 2015)
The goal of this research was to examine exploitation properties of Ni-Pd/Al2O3 catalyst supported on alpha-Al2O3 based foam in the dry methane reforming. The catalyst was prepared by using aerosol method. Chloride precursors ...
