(Elsevier, 2009)
The new metallophthalocyanine (Zn, Cu, Ni, Co) polymers containing 4,6,10,12,16,18,22,24-octakis(2-hydroxyethoxy)-2,8,14,20-tetramethylresorcinarene are described. Firstly, 4,6,10,12,16,18,22,24-octakis(2-hydroxyethoxy)- ...
The polarization of X-rays and magnetic photoionization cross-sections for L3 sub-shell
(Elsevier, 2009)
The alignment of atoms with inner-shell vacancies resulting from ionization by photons was investigated by measuring the anisotropic emission of L shell X-ray lines. The X-ray line intensities were measured using an Si(Li) ...

Fourier method for a quasilinear pseudo-parabolic equation with periodic boundary condition
(2009)
A multidimensional mixed problem with Neuman type periodic boundary condition is studied for quasilinear pseudo-parabolic equation ?u/?ta2 ?2u/?x2 - ? ?3u/?t?x2 = f(t, x, u). The existence, uniqueness and also convergence ...
Barbus niluferensis, a new species of barbel (Teleostei: Cyprinidae) from Nilüfer River, Turkey, with re-description of B. oligolepis
(Magnolia Press, 2009)
Barbus niluferensis, new species, is described from the Nilüfer River, Marmara Sea drainage, Turkey, It is distinguished by a weaker last simple dorsal-fin ray, serrated along the proximal half of its posterior margin, a ...
AC losses in a commercial Bi: 2223/Ag tape
(Institute of Physics Publishing, 2009)
We have investigated the effect of temperature, field amplitude, frequency and orientation of the field on AC losses in a commercial Bi:2223/Ag tape. The measurements were performed using an AC susceptometer. The experimental ...
Effects of x in Yb1-xGdxBa2Cu3O7-y samples on c-lattice parameter, activation energy and its magnetic power constant
(Elsevier, 2008)
The Yb1-xGdxBa2Cu3O7-y superconducting samples (x = 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0) which were prepared by solid-state reaction technique were studied to investigate the effect of x on c-lattice parameter, the activation ...
