Prediction for debonding damage process and effective elastic properties of glass-bead-filled modified polyphenylene oxide
(Elsevier Sci Ltd, Oxford, 2006)
A three-dimensional three-phase finite element unit cell model has been applied to predict the debonding damage process of particulate polymer composites (PPC) during tensile deformation. The model consists of a particle, ...
New analytical HFET I-V characteristics model
(Natl Inst Optoelectronics, Bucharest-Magurele, 2006)
In this paper the new analytical model of current - voltage characteristics of a Heterostructure Field Effect Transistor (HFET), is proposed. The model is relatively simple, and at the same time, it describes complex HFET ...
Heat transfer conditions and ultrasonic measurements of alumina based refractories
(CHISA 2006 - 17th International Congress of Chemical and Process Engineering, 2006)
In this paper temperature difference and resistance parameters were used for prediction of thermal shock behavior of alumina based commercial refractories with content of Al2O3 from 28 % to 78 %. Thermal and mechanical ...
The Candida rugosa lipase catalyzed synthesis of amyl isobutyrate in organic solvent and solvent-free system: A kinetic study
(Elsevier, Amsterdam, 2006)
The Candida rugosa lipase catalyzed esterification of butyric acid with amyl alcohol in isooctane and in solvent-free system was studied. Nearly complete conversion ( gt 95%) of substrates was achieved using low enzyme ...
Influence of electrode materials and the manner of electrode surface processing on gas-filled surge arresters relevant characteristics
(2006 25th International Conference on Microelectronics, MIEL 2006, 2006)
The aim of this paper is to present the electrode effects as approach for the improvement of gas filled surge arresters (GFSA) protective characteristics in the most optimal way. We examined the influence of the electrode ...
Surface characteristics and modification of different carbon materials
(7th Conference of the Yugoslav Materials Research Society - Recent Developments in Advanced Materials and Processes, YUCOMAT VII, 2006)
In this work, surface characteristics of different carbon materials were investigated. The materials under consideration were: activated carbon, carbon monolith, carbon felt and glassy carbon (powder, plate and broken ...
Effect of temperature on the excess molar volumes of some alcohol plus aromatic mixtures and modelling by cubic EOS mixing rules
(Elsevier, 2006)
Densities of the (methanol + benzene), (ethanol + benzene), (methanol + chlorobenzene) and (ethanol + chlorobenzene) mixtures have been measured at six temperatures (288.15, 293.15, 298.15, 303.15, 308.15 and 313.15 K) and ...
Prediction of the Lee retention indices of polycyclic aromatic hydrocarbons by artificial neural network
(Elsevier, Amsterdam, 2006)
A quantitative structure retention relationship technique using an artificial neural network (ANN) has been used for the prediction of the Lee retention indices for PAHs on SE-52 and DB-5 stationary phases. The selected ...
Supercritical carbon dioxide extraction and fractionation of hyper for in and adhyperforin from St. John's Wort (Hypericum perforatum L.)
(CHISA 2006 - 17th International Congress of Chemical and Process Engineering, 2006)
Plants of the genus Hypericum have been used as traditional medicinal plants in various parts of the world. St. John's Wort (Hypericum perforatum L.) has been reported as an antidepressive, antiviral, antimicrobial, ...
Application of nonlinear frequency response to investigation of membrane transport
(Taylor & Francis Inc, Philadelphia, 2006)
The concept of higher order frequency response functions, used for investigation of weekly nonlinear systems by frequency response techniques, is applied to investigation of membrane systems. Isothermal permeation of single ...
