Antioxidant and Anticholinesterase Activity Evaluation of ent-Kaurane Diterpenoids from Sideritis arguta
(Amer Chemical Soc, 2009)
The petroleum ether and acetone extracts of the aerial parts of Sideritis arguta afforded two new and six known diterpenoids with the ent-kaurane skeleton. The structures of the new diterpenoids were determined as ent-7 ...
Polynomial solution of high-order linear Fredholm integro-differential equations with constant coefficients
(Pergamon-Elsevier Science Ltd, 2008)
In this study, a practical matrix method is presented to find an approximate solution of high-order linear Fredholm integro-differential equations with constant coefficients under the initial-boundary conditions in terms ...
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, ...
Enhancement of flotation performance of oil shale cleaning by ultrasonic treatment
(Elsevier, 2009)
In this study, it was attempted to enhance the performance of flotation cleaning of oil shales by use of ultrasound. The use of an excitation effect through ultrasonication was investigated towards inorganic particles that ...
Double-walled carbon nanotube based carbon paste electrode as xanthine biosensor
(Springer Wien, 2009)
We describe the first usage of a double walled carbon nanotube (DWCNT) modified carbon paste electrode as biosensor transducer. Xanthine was chosen as a substrate for evaluation of the electrode performance. Proper amount ...
The In Vitro Antimicrobial Activities of the Essential Oils of Some Lamiaceae Species from Turkey
(Mary Ann Liebert, Inc, 2009)
In this study, antimicrobial activities of the essential oils obtained by using the hydrodistillation method from some lamiaceous plants-Mentha longifolia (L.) Hudson ssp. longifolia, M. longifolia (L.) Hudson ssp. typhoides ...
Tourist harassment - A marketing perspective
(Pergamon-Elsevier Science Ltd, 2007)
Consumer services research contains few empirical studies of harassment involving tourists. Previous studies are largely in general typological terms. Relatively little is known about the effects of harassment on tourist ...
Removal of cationic dyes by kaolinite
(Elsevier Science Bv, 2009)
The removal of cationic dyes such as maxilon yellow 4GL (MY 4GL) and maxilon red GIRL (MR GRL) on kaolinite from aqueous solutions has been studied according to the adsorption method. The adsorbed amount of dyes on kaolinite ...
Volumetric evaluation of the relations among the cerebrum, cerebellum and brain stem in young subjects: a combination of stereology and magnetic resonance imaging
(Springer France, 2008)
The Cavalieri estimator using a point grid is used to estimate the volume of three-dimensional structures based on two-dimensional slices of the object. The size of the components of intracranial neural structures should ...
