Chitosan/acid dye interactions in wool dyeing system
(Elsevier Sci Ltd, Oxford, 2005)
This study assesses the interactions that could occur during dyeing of the chitosan treated wool fibres on basis of the spectrophotometric study, by measuring the absorbance values of the solutions containing dye and ...
Colonic microbiota signatures across five northern European countries
(Amer Soc Microbiology, Washington, 2005)
The composition of the colonic microbiota of 91 northern Europeans was characterized by fluorescent in situ hybridization using 18 phylogenetic probes. On average 75% of the bacteria were identified, and large interindividual ...
Solids residence time distribution in gas-flowing solids-fixed bed contactors
(Amer Chemical Soc, Washington, 2005)
Flowing solids residence time distribution in gas-flowing solids-fixed bed contactors was investigated using a tracer technique with a step signal as input. Particles of different color (all other properties being the same) ...
Corrosion studies on electrochemically deposited PANI and PANI/epoxy coatings on mild steel in acid sulfate solution
(Elsevier Science Sa, Lausanne, 2005)
The corrosion behavior of mild steel and mild steel covered by electrochemically deposited (a) polyaniline (PANI) film, (b) epoxy coating
and (c) PANI/epoxy coating system in 0.1 M sulfuric acid solution were investigated ...
Determination of thermodynamic properties of macroporous glycidyl methacrylate-based copolymers by inverse gas chromatography
(Wiley, Hoboken, 2005)
Macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) (PGME) was synthesized by suspension copolymerization and modified by ring-opening reaction of the pendant epoxy groups with ethylene ...
Osmotic coefficient of K2SO4(aq) in supersaturated solution at T=298.15 K
(Amer Chemical Soc, Washington, 2005)
The Zdanovskii rule, in simple and modified form, was used for the estimation of supersaturated K2SO4-(aq) osmotic coefficients at T = 298.15 K by treatment of the isopiestic data of the mixed electrolyte solutions. The ...
Characterization of glycidyl methacrylate based copolymers by inverse gas chromatography under finite surface coverage
(Wiley-VCH Verlag Gmbh, Weinheim, 2005)
Inverse gas chromatography under finite surface coverage conditions (IGC-FC) was used for the investigation of sorption of hexane, benzene, chloroform and tetrahydrofuran on macroporous crosslinked poly[(glycidyl ...
Electrothermal desorption in an annular-radial flow - ACFC adsorber - Mathematical modeling
(Springer, New York, 2005)
A mathematical model of an annular, radial-flow adsorber with the possibility of electroresistive heating of the adsorbent bed has been postulated. The model consists of a set of coupled nonlinear PDEs, ODEs and algebraic ...
Determination of metal content in some herbal drugs - Empirical and chemometric approach
(Elsevier, Amsterdam, 2005)
The concentrations of Cu, Zn, Mn, Fe, K, Ca, Mg, Al, Ba and B in 26 herbal drugs of special importance in phytopharmacywere studied. Flame atomic absorption and emission spectrometry (FAAS, FAES), as well as inductively ...
Supercritical carbon dioxide essential oil extraction of Lamiaceae family species: Mathematical modelling on the micro-scale and process optimization
(Pergamon-Elsevier Science Ltd, Oxford, 2005)
In this paper the essential oil supercritical carbon dioxide extraction from leaves of Lamiaceae family species was studied. Recent investigations of Lamiaceae family essential oil storage have shown that most of the oil ...
