Pinus pinea (fıstık çamı) ormanları dünyada geni? bir yayılışa sahip değildir. Fıstık çamının dünyadaki yayılış alanları onun Akdeniz havzasına lokalize olmuş bir tür olduğuna işaret etmektedir. Bu çalışmada Türkiye'nin ...
Effect of silicon on plant growth and mineral nutrition of maize grown under water-stress conditions
(Taylor & Francis Inc, 2006)
The effect of silicon (Si) on physiological attributes and nutritional status of maize (Zea mays cv. DK 647 F1) under water stress was studied in a pot experiment. Treatments were (1) well watered (WW): 100% of FC (soil ...
Synthesis and spectroscopic studies of mixed-ligand and polymeric dinuclear transition metal complexes with bis-acylhydrazone tetradentate ligands and 1,10-phenanthroline
(Pergamon-Elsevier Science Ltd, 2006)
Two types of dinuclear copper(II) and nickel(II) complexes with two tetradentate N2O2 donor ligands 1,4-bis(1-anthranoylhydrazonoethyl)benzene (L-1), 1,4-bis(1-salicyloylhydrazonoethyl)benzene (L-2) and N,N '-bidentate ...
Free-radical scavenging capacity and antimicrobial activity of wild edible mushroom from Turkey
(Academic Journals, 2006)
Antioxidant capacity and antimicrobial activities of Ramaria flava (Schaeff) Quel. (RF) extracts obtained with ethanol were investigated in this study. Four complementary test systems; namely DPPH free radical scavenging, ...
A study on the humidity sensing properties of ZnCr2O4-K2CrO4 ionic conductive ceramic sensor
(Elsevier Science Sa, 2006)
The response to humidity of ZnCr2O4-K2CrO4 ceramic composites formed by solid-state reaction at elevated temperatures is studied. The fired ceramic body, which proved to be mainly constructed from ZnCr2O4 spinel grains, ...

Three types of copper complexes as well as an oximate-bridged nickel complex with isonitrosoacetophenone 2-aminobenzoylhydrazone (H2L) have been prepared in ethanolic solution and characterized by elemental analyses, IR, ...
A biosensor based on graphite epoxy composite electrode for aspartame and ethanol detection
(Elsevier Science Bv, 2006)
A gelatin membrane with carboxyl esterase and alcohol oxidase was subsequently integrated onto the surface of a graphite epoxy composite electrode (GECE). The developed biosensors showed linearity in the range of 2.5-400 ...
Lattice vibrations of pure and doped GaSe
(Pergamon-Elsevier Science Ltd, 2006)
The Bridgman method is used to grow especially undoped and doped single crystals of GaSe. Composition and impurity content of the grown crystals were determined using X-ray fluorescence (XRF) method. X-ray diffraction, ...
