In this article, using the generalized Newton transformation, we define higher order mean curvatures of distributions of arbitrary codimension and we show that they agree with the ones from Brito and Naveira [F. Brito, A.M. Naveira, Total extrinsic curvature of certain distributions on closed spaces of constant curvature, Ann. Global Anal. Geom., 18 (2000) 371–383]. We also introduce higher order mean curvature vector fields and we compute their divergence for certain distributions and using this we obtain total extrinsic mean curvatures. 相似文献

We report a tethered poly(3,4-propylenedioxythiophene) derivative with a built-in polymer conformation restriction which locks the conjugated chain at a specific dihedral angle, thus providing a handle in which to tune the optical and electronic properties of the material. 相似文献

A sensitive and specific liquid chromatography tandem mass spectrometry method with electrospray ionization for the determination of endothelin-1 in rat plasma and lung effluents has been developed and validated. Detection was achieved by an Applied Biosystems MDS Sciex API 2000 triple quadrupole mass spectrometer coupled to an Agilent 1100 LC system. The limit of detection and the limit of the quantification of ET-1 in matrix buffer was estimated at 40 pM and 1 nM, respectively. The precision and accuracy for both intra- and inter-day determination of the analyte ranged from 2.5% to 14.7% and from 104.2% to 113.3%, respectively. No significant relative matrix effect was observed. Stability of ET-1 established in a bench-top, autosampler, long-term storage stability as well as freeze/thaw cycles shown no significant degradation products in the samples. The results of the method validation indicated that this method is applicable for the determination of the ET-1 concentration in an effluent from the isolated lung preparation as well as in vivo in plasma samples to evaluate ET-1 as a potential biomarker of the progression of pulmonary endothelial dysfunction and pulmonary hypertension in rats induced by a monocrotaline injection. 相似文献

We investigate an optimal control problem described by a second-order ordinary differential equation on the interval ]0,∞[
and an integral cost functional. The study of this problem is based on a variational approach. 相似文献

The phase equilibria established up to the solidus line in the system Fe2V4O13−WO3, one of the intersections of the three-component system Fe2O3−V2O5−WO3, have been studied. The system appears not to be a real two-component system.
Zusammenfassung Es wurde eine Untersuchung des Phasengleichgewichtes durchgeführt, welches bezüglich der Solidus-Linie im System Fe2V4O13−WO3, einer der Zwischenbereiche im Dreikomponentensystem Fe2O3−V2O5−WO3, nachgewiesen wurde. Dieses System scheint kein echtes Zweikomponentensystem zu sein.相似文献

Studies on the three-component system Fe2O3-V2O5-WO3 have shown the occurrence of a new, compound with molecular formula FeVW2O10. Its X-ray characteristics and its melting temperature, 865±10 °C, have been established.
Zusammenfassung Einleitende Untersuchungen am Dreikomponentensystem Fe2O3-V2 O5-WO3 zeigten das Auftreten einer neuen, noch nicht publizierten Verbindung der Formel FeVW2O10. Die Verbindung wurde röntgenographisch beschrieben, ihr Schmelzpunkt beträgt 865 ±10°C.相似文献

Using DTA and X-ray phase diffraction methods, a diagram of phase equilibria established in two sections of a tricomponent
oxide triangle Fe2O3-V2O5-WO3was constructed, that is, in the sections: Fe8V10W16O85-Fe2O3and Fe8V10W16O85-Fe2WO6.
