Synthesis, characterization and cyclization reactions of some new bisthiosemicarbazones
(Arkat, 2009)
The reaction of trans-1, 4-dichloro-2-butene 1 with selected phenols affords (E)-1, 4-bis(aryloxy)-2-butenes 2a-d which are converted into bis-thiosemicarbazones 3a-h via the reactions with thiosemicarbazide and 4-methyl ...
Chemical composition and antimicrobial activity of essential oils from Centaurea appendicigera and Centaurea helenioides
(Taylor & Francis LTD., 2009)
The chemical components and antimicrobial activity of the essential oils from Centaurea appendicigera C. Koch and Centaurea helenioides Boiss, two different endemic members of the genus Centaurea L. (Asteraceae), were ...
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 ...
Sulphur and some heavy metal contents in foliage of Corylus avellana and some roadside native plants in Ordu province, Turkey
(Ekoloji, 2009)
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 ...
Synthesis of methyl (E)-2′,4″-thiazachalcones and their N-alkyl derivatives, photochemistry with theoretical calculations and antimicrobial activities
(TUBİTAK, 2009)
A series of 9 new (E) -thiazachalcones (1-3), and their N -alkyl substituted derivatives (4-6), and stereoselective dimerization products (7-9) were synthesized, then tested for antimicrobial activity against all test ...
Relationships between vegetation zonation and edaphic factors in a salt-marsh community (Black Sea coast)
(2009)
The effects of pH, electrical conductivity (EC), soluble cations (Na +, K +, Ca 2+, Mg 2+), and soluble anions (HCO 3 -, Cl -, SO 4 2-) on vegetation zonation in a salt-marsh community (Black Sea coast) were investigated ...
PCR based idendification and discrimination of Caranx rhonchus (Pisces, Carangidae) based on nuclear and mtDNA sequences
(2009)
PCR based nuclear and mitochondrial DNA markers are used to clarify cases of misidentification of adult individuals of fish species with morphological similarities. This problem prevails in the case of false scad (Caranx ...
