Synthesis and characterization. of complexes of Ni(II), Co(II), and Cu(II) with four 4-aminobenzoate derivatives of unsymmetrical vic-dioximes
(Taylor & Francis Inc, 2002)
Four different 4-aminobenzoate derivates of vic-dioximes Were synthesized. Their transition metal complexes with Ni(II), Co(II) and Cu(II) were prepared with a metal-ligand ratio of 1:2. The unsymmetrical complexes are in ...
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 ...
Statistical principal components analysis for retrieval experiments
(Wiley, 2007)
In this article, the statistical principal components analysis (PCA) is proposed as a method for performance comparisons of different retrieval strategies. It is shown that the PCA method can reveal implicit performance ...

Withdrawal capacity of pinned and unpinned round mortise and tenon furniture joints
(Forest Products Soc, 2004)
Tests were conducted to determine the withdrawal capacity of cross-pinned round mortise and tenon joints. Tenon diameters ranged from a nominal 0.6 to 1.0 inches. Cross-pins were about one-half the diameter of the tenons. ...
Effect of hole diameter, hole distance from the edge, and material properties on lateral pin holding strength of medium density fiberboard and particleboard
(Forest Products Soc, 2004)
There is no established standard which evaluates the lateral holding resistance of wood composites. The method of test offered in this study intends to determine the lateral resistance of panels used in case constructions ...
The effect of repeated annealing temperature on the structural, optical, and electrical properties of TiO2 thin films prepared by dip-coating sol-gel method
(Springer, 2009)
In this study, we have studied the effect of repeated annealing temperatures on TiO2 thin films prepared by dip-coating sol-gel method onto the glasses and silicon substrates. The TiO2 thin films coated samples were ...
N-salicylidene anilines and their copper complexes: comparative investigations of mesomorphic, morphologic, thermotropic and thermodynamical properties
(Taylor & Francis Ltd, 2006)
In this work comparative studies of the mesomorphic and morphologic properties and thermal behaviour of new Schiff base N-salicylidene aniline ligands and the effects of Cu(II) additions on these properties have been carried ...
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. ...
Raman scattering under pressure and the phase transition in epsilon-GaSe
(Wiley-V C H Verlag Gmbh, 2003)
Raman scattering in epsilon-GaSe has been investigated at room temperature in a diamond anvil cell by using helium gas as a pressure transmitting medium. The first observation of the solid-solid phase transition under ...
