Deformation pattern and strain hardening in a highly textured 8090 Al-Li alloy sheet
(Elsevier Science Sa, Lausanne, 2000)
Structure-deformation pattern analysis was made on a highly textured 8090 AI-Li alloy sheet deformed in tension. It is shown that the sharp beta-fiber type crystallographic texture induces a strong orientation variation ...
Microstructure and mechanical properties of Al-4·4 wt-%Mg alloy (AA5182) after equal channel angular pressing
(Maney Publishing, 2005)
Equal channel angular pressing (ECAP) has been used to process an Al-4-4 wt-%Mg alloy (AA5182) at room temperature (RT), 200°C and 400°C. The evolution of microstructure and mechanical properties after ECAP has been studied ...
UV-curable hyperbranched urethane acrylate oligomers containing soybean fatty acids
(Elsevier Science Sa, Lausanne, 2005)
Urethane acrylate resins based on partially modified aliphatic hyperbranched polyesters (HBP) have been synthesized. HBP of the second and the third generation were synthesized from 2,2-bis(hydroxymethyl)propionic acid and ...
Optimization of artificial neural network for retention modeling in high-performance liquid chromatography
(Elsevier, Amsterdam, 2004)
An artificial neural network (ANN) model for the prediction of retention times in high-performance liquid chromatography (HPLC) was developed and optimized. A three-layer feed-forward ANN has been used to model retention ...
Application of Nonlinear frequency response to adsorption systems with complex kinetic mechanisms
(Springer, Dordrecht, 2005)
The paper is a contribution to formation of a library of sets of frequency response functions of different orders, for complex kinetic mechanisms typical for adsorption on bidispersed sorbents. The first and second order ...
Predictive modeling of the mechanical properties of particulate hydroxyapatite reinforced polymer composites
(Wiley, Hoboken, 2002)
The influence of particle geometry and volume fraction on the mechanical properties of a hydroxyapatite (HAp) particulate reinforced polymer (poly-L-lactide and collagen) matrix composite was investigated through finite-element ...
The non-oxidative thermal degradation of poly(di-n-alkyl itaconates). I. Analysis of the thermolysis volatiles
(Elsevier Sci Ltd, Oxford, 2005)
The volatiles arising from the thermal degradation of poly(di-n-alkyl itaconates) with ester substituents ranging from methyl to n-octyl were analysed. The corresponding monomer was found to be the major degradation product. ...
Thermal stability of starch benzoate
(Elsevier Sci Ltd, Oxford, 2005)
Starch esterification with benzoyl chloride was performed in two steps, the first being the alkali treatment of the starch and the second, esterification. Samples of hydrophobic starch benzoate were synthesized with degrees ...
Classification of soil samples according to geographic origin using gamma-ray spectrometry and pattern recognition methods
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Multivariate data analysis methods were used to recognize and classify soils of unknown geographic origin. A total of 103 soil samples were differentiated into classes, according to regions in Serbia and Montenegro from ...
