(Allured Publ Corp, 2000)The oil of Lallemantia peltata (L.) Fisch. et Mey. (Labiatae) obtained by Simultaneous Distillation-Extraction (SDE) using Likens-Nickerson apparatus, was analyzed by GC/MS. Thirteen compounds were identified representing ... -
Critical factors in the templated grain growth of textured reaction-bonded alumina
(Wiley-Blackwell, 2000)The Templated Grain Growth (TGG) of Al2O3 occurs in three stages: densification, radial growth of individual template grains until template impingement, and template grain thickening. Significant template growth occurs ... -
Essential oil of Hippomarathrum boissieri Reuter et Hausskn.
(Allured Publ Corp, 2000)The essential oil hydrodistilled from herbal parts of Hippomarathrum boissieri (Umbelliferae), was analyzed by GC/MS. Eighty-nine compounds representing 92.4% of the oil were identified with beta-caryophyllene (25.6%) and ... -
Lipids and essential oil of Origanum onites
(Consultants Bureau, 2000)Neutral lipids, glycolipids, phospholipids, pigments, and essential oil of the above-ground part of Origanum onites L. (Lamiaceae) are isolated and characterized for the first time. The fatty-acid composition of the lipids ... -
The composition and antifungal bioassay of the essential oils of different Betula species growing in Turkey
(Consultants Bureau, 2000)Five Betula species, B. pendula, B. browicziana, B. medwediewii, B. litwinowii, and B. recurvata, were collected from different parts of Turkey. The leaves of these species were hydrodistilled to yield the consequent ... -

(John Wiley & Sons LTD, 2000)Water-distilled essential oil of Cinnamomum tamala (Ham.) Nees & Eberm. (Lauraceae) leaves was analysed by CC-MS. Sixty-three compounds, representing 94.3% of the oil, were identified. beta -Caryophyllene (25.3%), linalool ... -
Paley inequalities for discrete-time rational orthonormal bases
(Elsevier Science BV, 2000)In this paper, we derive some inequalities which provide information about the Fourier coefficients of linear-time-invariant discrete-time systems with respect to the bounded rational orthonormal basis functions studied ... -
Adaptive polyphase subband decomposition structures for image compression
(IEEE-Inst Electrical Electronics Engineers Inc, 2000)Subband decomposition techniques have been extensively used for data coding and analysis. In most filter banks, the goal is to obtain subsampled signals corresponding to different spectral regions of the original data. ... -
On the existence of a disk algebra basis
(Elsevier Science BV, 2000)In this paper, approximation of discrete-time systems by fixed pole orthonormal basis functions is investigated. It is shown that if accumulation points of basis poles do not cover the entire unit circle, then the Fourier ... -
Simultaneous computer control of pH in multiple environmental laboratory bioreactors
(Selper LTD, Publications Div, 2000)This paper describes the design, construction and operation of a computerized pH control system for environmental laboratory reactors. Since pH is often a key environmental parameter in environmental process reactors, it ... -
Case studies on the use of neural networks in eutrophication modeling
(Elsevier Science BV, 2000)Artificial neural networks are becoming more and more common to be used in development of prediction models for complex systems as the theory behind them develops and the processing power of computers increase. A three ... -
Synthesis and preliminary evaluation of new 5-pyrazolinone derivatives as analgesic agents
(Editions Scientifiques Medicales Elsevier, 2000)New 4-(aroyloxyalkanoyl)-2,3-dimethyl-1-phenyl-3-pyrazolin-5-ones (5) were cyclized to 4-(2-aryl-5-unsubstituted/substituted oxazol-4-yl)-2,3-dimethyl-1-phenyl-3-pyrazolin-5-ones (6) employing the Davidson procedure. ... -
New heat treatment methods for glass removal from silicon nitride and sialon ceramics
(Kluwer Academic Publ, 2000)Sialon ceramics were discovered simultaneously (but independently) in late 1971 at Newcastle University and also at the Toyota Research Laboratories in Japan. During the 30 years since their original discovery, the Newcastle ... -
Testing wound-healing activity in T15 fibroblast cultures: A morphometric analysis
(Frame, 2000)The purpose was to evaluate the use of mouse T15 fibroblast cell cultures for the investigation of wound-healing activity. In order to investigate their mechanisms of action, the effects of drugs with wound-healing activities ... -
