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 ...
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, ...
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 ...
Photosystem II functionality and antioxidant system changes during leaf rolling in post-stress emerging ctenanthe setosa exposed to drought
(2009)
We studied the changes in antioxidant system and chlorophyll fluorescence parameters in post-stress emerging Ctenanthe setosa (Rosc.) Eichler (Marantaceae) plants (PSE plants) having reduced leaf area under drought stress ...

The concentration of sulphur and some heavy metals the leaves of Corylus avellana, Alopecurus myosuroides, Helleborus orientalis, Glechoma hederacea, Calamintha nepeta and Urtica dioica were determined around the "polluted ...
Effects of sexual reproduction on growth and vegetative propagation in Arum Maculatum L. (Araceae): Insitu removal experiments
(2009)
We investigated the effects of sexual reproduction on vegetative propagation and relative somatic cost in Arum maculatum L. (Araceae). Two groups were selected as control and experimental. The spadices of individuals in ...
