The evolution of hydrogen from proton irradiated glassy carbon
(Elsevier B.V., 2011)
Glassy carbon was irradiated with 15 key H(+) ion beam. It was observed that the implanted hydrogen is unstable in material and evolves as H, H(2) and H(2)O. Post-irradiation evolution of H, H(2) and H(2)O from proton ...
Nutrient Composition of Three Mangulica Pork Cuts from Serbia
(Humana Press Inc., 2018)
The purpose of this study was to analyze and evaluate the levels of essential elements (Mn, Fe, Cu, Zn, and Se) and proximate composition (moisture, protein, fat, and ash) of three pork cuts (loin, hind leg, and shoulder) ...
3D Digital Image Correlation Analysis of the Shrinkage Strain in Four Dual Cure Composite Cements
(Hindawi Limited, 2019)
The introduction of resin-based cements and an adhesive-bonding system in daily dental practice has given the opportunity to increase the retention of previously conventional cemented restorations and the optimal results ...
Determination of the Load Carrying Capacity of Damaged Pipes Using Local Approach to Fracture
(Japan Inst Metals, Sendai, 2012)
The subject of this study was the application of local approach to ductile fracture in order to estimate the integrity of damaged seam casing pipes for oil and gas drilling rigs. The experimental testing included tensile ...
Efficient immobilization of lipase from Candida rugosa by entrapment into poly(N-isopropylacrylamide-co-itaconic acid) hydrogels under mild conditions
(Springer, New York, 2012)
Temperature and pH-sensitive hydrogels, based on N-isopropylacrylamide and itaconic acid, with varying comonomer ratios and crosslinking agent content, were prepared by free radical crosslinking copolymerization. The ...
Heat generation during plunge stage in friction stir welding
(Vinca Institute of Nuclear Sciences, 2013)
This paper deals with the heat generation in the Al alloy Al2024-T3 plate under different rotating speeds and plunge speeds during the plunge stage of friction stir welding. A 3-D finite element model is developed in the ...
Effect of material heterogeneity and constraint conditions on ductile fracture resistance of welded joint zones - Micromechanical assessment
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
The topic of this work is assessment of ductile fracture initiation and development in different zones of welded joint of a high strength low alloyed (HSLA) steel. A combined experimental-numerical procedure is applied for ...

(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
This paper presents experimental and numerical analysis of the change of temperature and force in the vertical direction during the friction stir welding of high-strength aluminium alloy 2024 T3. This procedure confirmed ...
Batch and semicontinuous production of L-ascorbyl oleate catalyzed by CALB immobilized onto Purolite (R) MN102
(Elsevier, Amsterdam, 2017)
L-Ascorbyl oleate is recognized as efficient liposoluble antioxidant and biosurfactant which can be synthesized by using immobilized lipases as catalysts in organic media. However, development of economical production ...
Molecular structure of carboxymethyl starch in dilute aqueous sodium chloride solutions
(Wiley-VCH Verlag, 2013)
The dilute solution behavior of six carboxymethyl starch (CMS) samples was investigated in aqueous NaCl solutions of different concentration (0.01, 0.05, 0.1, and 0.5 M) by dynamic light scattering (DLS) at 25°C. The values ...
