Approximate solution of multi-pantograph equation with variable coefficients
(Elsevier, 2008)
This paper deals with the approximate solution of multi-pantograph equation with nonhomogenous term in terms of Taylor polynomials. The technique we have used is based on a Taylor matrix method. In addition, some numerical ...
Silica gel functionalized with 4-phenylacetophynone 4-aminobenzoylhydrazone: Synthesis of a new chelating matrix and its application as metal ion collector
(Elsevier Science Bv, 2008)
The silica gel surface immobilized with 4-phenylacetophynone 4-aminobenzoylhydrazone (PAAH) after surface modification by 3-chloropropyltrimethoxysilane (CPTS). The modified silica gel was used for sorption of Cu(II), ...
Comparison of textile dyeing effluent adsorption on commercial activated carbon and activated carbon prepared from olive stone by ZnCl2 activation
(Elsevier, 2008)
Adsorption of Remazol Red B on activated carbon prepared from olive stone and commercial activated carbon from aqueous solutions was compared. Different activating agent (ZnCl2) amounts and adsorbent particle size were ...
Influence of frequency and bias voltage on dielectric properties and electrical conductivity of Al/TiO2/p-Si/p(+) (MOS) structures
(Iop Publishing Ltd, 2008)
In this study, the frequency and voltage dependence of the dielectric constant (epsilon'), dielectric loss (epsilon ''), loss tangent (tan delta), electric modulus (M' and M '') and ac electrical conductivity (sigma(ac)) ...
Polynomial solution of high-order linear Fredholm integro-differential equations with constant coefficients
(Pergamon-Elsevier Science Ltd, 2008)
In this study, a practical matrix method is presented to find an approximate solution of high-order linear Fredholm integro-differential equations with constant coefficients under the initial-boundary conditions in terms ...
Design, performance, and calibration of CMS forward calorimeter wedges
(Springer, 2008)
We report on the test beam results and calibration methods using high energy electrons, pions and muons with the CMS forward calorimeter (HF). The HF calorimeter covers a large pseudorapidity region (3 <= vertical bar eta ...
Effects of atmospheric plasma treatment on the dyeability of cotton fabrics by acid dyes
(Blackwell Publishing, 2008)
Cotton fabrics were treated with air and argon atmospheric plasma for surface activation. Activated surfaces were grafted with two different amine compounds: ethylenediamine and triethylenetetramine. Pretreated cotton was ...
Unparticle effects in rare t -> cgg decay
(Amer Physical Soc, 2008)
In this work the flavor-changing, rare t -> cgg decay induced by mediation of scalar and tensor unparticles is studied. Using the standard model result for the branching ratio of the t -> cgg decay, the parameter space of ...
Measurement and comparison of silicon p-i-n-photodiodes with ac impedance at different voltages
(Maik Nauka/Interperiodica/Springer, 2008)
The dark alternating current (ac) parameters of commercially available silicon p-i-n-photodiodes are measured and compared at room temperature both in forward and reverse bias using the impedance spectroscopy technique. ...
