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, ... -
Studies on the protonation constants of some triazoles in ethanol-water mixtures
