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)) ...
Comparison of point counting and planimetry methods for the assessment of cerebellar volume in human using magnetic resonance imaging: a stereological study
(Springer France, 2008)
The cerebellum is involved in motor learning and cognitive function in human. Many studies have been conducted to assess the cerebellar volume. To the best of our knowledge, there is no cerebellar volume study evaluating ...
The hematological effects of methyl parathion in rats
(Elsevier Science Bv, 2008)
The effects of methyl parathion (MP) at sublethal concentration on hematological constituent [red blood corpuscles (RBC), white blood corpuscles (WBC), mean cell volume (MCV), mean corpuscular hemoglobin (MCH), mean ...
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 ...
Volumetric evaluation of the relations among the cerebrum, cerebellum and brain stem in young subjects: a combination of stereology and magnetic resonance imaging
(Springer France, 2008)
The Cavalieri estimator using a point grid is used to estimate the volume of three-dimensional structures based on two-dimensional slices of the object. The size of the components of intracranial neural structures should ...
Lightlike hypersurfaces in semi-Riemannian manifold with semi-symmetric non-metric connection
(Matematisk Inst, 2008)
In this paper, We Study lightlike hypersurfaces of a semi-Riemannian manifold admitting a semisymmetric non-metric connection. We give the equations of Gauss and Codazzi. Then, we obtain conditions under which the Ricci ...
