Antimicrobial activity and essential oil compositions of two Ranunculus species from Turkey: R. constantinopolitanus and R. arvensis
(2008)
The isolated essential oils of Ranunculus constantinopolitanus and Ranunculus arvensis were tested for antimicrobial activity against the bacteria E. coli, K. pneumoniae, P. aeruginosa, E. faecalis, S. aureus, B. cereus ...
Role of coexistence of superconductivity and paramagnetism in magnetostriction of high-T c superconductors
(Springer, 2008)
Total magnetostriction in the superconducting state for high-T c superconductors has been separated into critical state and paramagnetic components in terms of a H (x) dependent magnetic flux density. We show that the ...
Modeling of normal-state like contribution on the pinning induced magnetostriction
(Elsevier, 2008)
To describe the change of the sign of the magnetostriction at the field close to the upper critical field, Bc2, which were observed in some magnetostriction measurements carried out on the type-II superconductors, theoretical ...
Effect of ascorbic acid supplementation on sperm quality of rainbow trout (Onchorynchus mykiss)
(2008)
The aim of the work was to determine the effects of two different doses of ascorbic acid (300 mg kg-1 and 800 mg kg-1). They were evaluated on sperm quality of rainbow trout. The results of study showed that 800 mg kg-1 ...
Fourier method for a quasilinear parabolic equation with periodic boundary condition
(Hacettepe University, 2008)
A multidimensional mixed problem with Neuman type periodic boundary condition is studied for the quasilinear parabolic equation ?u/?t-a2 ?2u/?x2 = f(t, x, u). The existence, uniqueness and also continuity of the weak ...
First record of Chromogobius zebratus (Gobiidae) for the mediterranean coast of Turkey
(TUBİTAK, 2008)
The Kolombatovic's goby Chromogobius zebratus, was caught for the first time from the Turkish coast of the Mediterranean Sea. The lateral-line system and morphometric features of this species were examined. © Tübitak.
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 ...
Lattice operations of positive bilinear mappings
(Mathematical Society of the Rep. of China, 2008)
In this paper we establish extension theorems for additive mappings ? : A+ ×B+ ? C+, where A, B are Riesz spaces (lattice ordered spaces or vector lattices) and C is an order complete Riesz space, to the whole of A×B, ...
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 ...
The Benthic exotic species of the Black Sea: Blood cockle (Anadara inaequivalvis, Bruguiere, 1789: Bivalve) and Rapa whelk (Rapana thomasiana, Crosse, 1861: Mollusc)
(2009)
The Black Sea is in transition from a freshwater to a marine environment and has a very low biodiversity. Therefore, it appears to be particularly vulnerable and easy target for many exotic species. Anthropogenic introductions ...
