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 ...
Artificial neural network modelling of uncertainty in gamma-ray spectrometry
(Elsevier, Amsterdam, 2005)
An artificial neural network (ANN) model for the prediction of measuring uncertainties in gamma-ray spectrometry was developed and optimized. A three-layer feed-forward ANN with back-propagation learning algorithm was used ...
The diffusion of water in poly(ditetrahydrofurfuryl itaconate)
(Elsevier Sci Ltd, Oxford, 2005)
The diffusion of water into solid poly(ditetrahydrofurfuryl itaconate) (PDTFI) films and in analogous polymer solutions was measured. Diffusion into solid PDTFI films on a glass support was measured in three solutions of ...
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 ...
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 ...
Using the image analysis program for prediction of thermal stability behavior of refractory specimen
(8th International Symposium on Multifunctional and Functionally Graded Materials, FGM2004, 2005)
Most important properties which are usually measured for refractories are work temperature and thermal stability. Thermal stability of the alumina based samples was measured using a standard laboratory procedure, the water ...
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 ...
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 ...
Aramid fiber reinforced laminar thermoplastic composite materials
(Journal of Advanced Materials, 2005)
In order to obtain a composite material with desired improved resistance to penetration of ballistic projectile, a poly(p-phenyleneterephthalamide) reinforced laminar thermoplastic composite material has been made. This ...
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) ...
