Arrovian impossibilities in aggregating preferences over non-resolute outcomes
(Springer, 2008)
Let A be a set of alternatives whose power set is A. Elements of A are interpreted as non-resolute outcomes. We consider the aggregation of preference profiles over A into a (social) preference over A. In case we allow ...
Studies on the protonation constants of some triazoles in ethanol-water mixtures
(Chemical Publishing Co., 2008)
Several studies, involving the formation and investigation of biological activities of some triazoles derivatives. These derivatives have weak acidic properties. To gain more information about the effect of solvent on ...
An extended model for coexistence of superconductivity and paramagnetism in high-Tc superconductors
(2008)
In the present work, the total magnetization in superconducting state is separated into critical state and paramagnetic components in terms of an H(x)-dependent magnetic flux density. Utilizing this model, we reproduce ...
Variation of K X-ray fluorescence cross-sections of Cu, Y and Ba in Y Ba2Cu3O7-δ superconductor
(Elsevier, 2009)
K X-ray fluorescence cross-sections of Cu, Y and Ba elements were measured in CuO, Y 2O3, BaCO3 compounds and Y Ba2Cu3O7-? superconductor samples (nonreacted agent, calcined and sintered states). A superconductor sample ...
Phylogeny of neurergus crocatus and neurergus strauchii in Turkey based on morphological and molecular data
(2009)
We described the phylogeny of the salamandrid genus Neurergus in Turkey using statistical analyses on morphometric characters and a molecular analysis based on 12S and 16S rRNA genes. Two different species, Neurergus ...
Dynamic phase diagrams of a mixed spin-1 and spin-5/2 Ising system in an oscillating magnetic field
(2009)
We study the nonequilibrium aspects of the kinetics of a mixed spin-1 and spin-5/2 Ising system, including the biquadratic nearest-neighbor pair interaction (K) and the crystal-field interaction (D), under the presence of ...
Synthesis of some new 1,2,4-triazoles, their Mannich and Schiff bases and evaluation of their antimicrobial activities
(Elsevier, 2009)
4-Phenyl-5-pyridin-4-yl-4H-1,2,4-triazole-3-thiol (3) was obtained in basic media via the formation of 2-isonicotinoyl-N-phenylhydrazinecarbothioamide (2), and converted to some alkylated derivatives (4a,b) and Mannich ...
Determination of the protonation constants of triazole derivatives in non-aqueous solvents
(2009)
Different 17 triazole derivatives were titrated with tetrabutylammonium hydroxide in four non-aqueous solvents (isopropyl alcohol, rert-butyl alcohol, N,N-dimethylformamide and acetonitrile), using Potentiometric method. ...
Capoeta mauricii n. sp., a new species of cyprinid fish from lake beyşehir, turkey: (Osteichthyes: Cyprinidae)
(Taylor & Francis, 2009)
Capoeta mauricii n. sp. is described from the Lake Beyşehir drainage, in Central Anatolia, Turkey. It is distinguished from other Anatolian Capoeta by having the lips somewhat fleshy and lower lip with developed lateral ...
Investigation of some superconducting properties of ytterbium diffusion-doped YBa2Cu3O7-x superconductors
(Elsevier, 2008)
The effect of Yb diffusion on structural evolution and superconducting properties of YBa2Cu307-x (Y123) prepared in the bulk polycrystalline form were studied. The ytterbium (Yb) diffusion in superconducting Y123 ceramic ...
