Quality of chemically modified hemp fibers
(Elsevier Sci Ltd, Oxford, 2008)
Hemp fibers are very interesting natural material for textile and technical applications now. Applying hemp fibers to the apparel sector requires improved quality fibers. In this paper, hemp fibers were modified with sodium ...
Re-refining of waste mineral insulating oil by extraction with N-methyl-2-pyrrolidone
(Elsevier Science Bv, Amsterdam, 2006)
Extraction with N-methyl-2-pyrrolidone (NMP) via the three-stage mixer-settler operation was studied as possible process for re-refining of waste mineral insulating oil. The following extraction process parameters were ...
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, ...
In situ stabilization of toxic metals in polluted soils using phosphates: theoretical prediction and experimental verification
(Elsevier, Amsterdam, 2005)
The in situ (in place) immobilization of toxic metals, using inexpensive "reactive" amendments, is considered as a simple and cost-effective approach for the treatment of soils, contaminated by the presence of heavy metals, ...
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 ...
Characterization of microflora in homemade semi-hard white Zlatar cheese
(Elsevier Science Bv, Amsterdam, 2007)
The Zlatar cheese belongs to the group of traditionally homemade cheeses, which are produced from nonpasteurized cow's milk, without adding of any bacterial starter culture. Changes were followed in lactic acid bacteria ...
Glycosaminoglycan deposition in engineered cartilage: Experiments and mathematical model
(Wiley-Blackwell, Malden, 2000)
Functional cartilaginous constructs for scientific research and eventual tissue repair were cultivated in bioreactors starting from chondrocytes immobilized on polymeric scaffolds. The scaffolds gradually degraded as the ...
Immobilization of yeast cells in PVA particles for beer fermentation
(Elsevier Sci Ltd, Oxford, 2007)
In this study, the potential of application of non-aggressive LentiKat (R) technique for brewer's yeast immobilization on polyvinyl alcohol was assessed. High cell loads of about 109 cells/ml were achieved by this procedure ...
Estimation of single solute adsorption isotherms applying the nonlinear frequency response method using non-optimal frequencies
(Elsevier, Amsterdam, 2008)
In order to estimate single solute adsorption isotherms, the nonlinear frequency response (FR) of a chromatographic column is analyzed experimentally and evaluated using the concept of higher order frequency response ...
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 ...
