The molecules of the title compound, [Mn(C(7)H(4)NO)(C(16)H(14)N(2)O(2))]·H(2)O, form dimers in the solid state across a crystallographic inversion center. The bridging Mn(2)O(2) group is built of phen-oxy groups, and is asymmetric, with an Mn-O distances of 1.9002 (13) and 2.6236 (14) Å. A substantial cavity between the two Mn atoms [Mn⋯Mn = 3.5082 (4) Å] is produced by the formation of the di...

Current studies on the fatigue lifetime of ceramics are mostly focused on the relation between the stress amplitude (or maximum stress) and cycles to failure. For a more compliant and plastic ceramic which has a pronounced nonlinear stress-strain relation, the role of plastic strain in the fatigue damage is investigated for the first time in this study using a 12 mol% Ce-TZP. By testing at diff...

Zusammenfassung Die Softwaretechnik an Hochschulen versteht sich meist als anwendungsorientierte (Ingenieur-) Wissenschaft. Was sind aus heutiger Sicht ihre wissenschaftlichen Fundamente für die Lehre, und wie stabil sind sie? Professionelle Softwareentwicklung sollte sich an wissenschaftlichen Konzepten und Ergebnissen orientieren. Umgekehrt sollte die Praxis auch Impulse für die anwendungsori...

Zusammenfassung. In vielen Bildverarbeitungsaufgaben stellt die Segmentierung einen wichtigen Schritt zur analytischen Auswertungsphase dar. Ihr Ziel im Dreidimensionalen ist es, einen Volumendatensatz in eine Menge von Regionen aufzuteilen, die in Bezug auf gewisse Eigenschaften homogen sind. Das Ergebnis dient meist als Basis für eine anschließende Klassifizierung. Die hier vorgestellte Segme...

In the title compound, C(6)H(6)F(5)NS, the environment of the S atom is roughly octa-hedral. The axial F-S bond appears slightly elongated with respect to the four equatorial F-S bonds. Equatorial F atoms are staggered with respect to the benzene ring. The N atom is displaced from the benzene plane by 0.154 (4) Å. The F-S-C-C torsion angles differ greatly from the values observed in the related...

The von Neumann stabil i ty criterion is employed in analyzing the stabili ty of a class of difference schemes for initial-value problems involving linear parabolic partial differential equations, u t = A u. I t is shown that , cont rary to the usual rule of thumb, there exist completely implicit difference schemes which are uncondit ionally unstable. Further , it is shown that the stabili ty p...

Fallot tetralojisi en sık görülen siyanotik doğumsal kalp hastalığıdır. Bu hastalarda doğum sonrası meydana gelen ani hemodinamik değişiklikler ciddi, yaşamı tehdit eden multiorgan komplikasyonlarına yol açar. Bu yüzden anestezi seçimi zordur. Otuz üç haftalık düzeltilmemiş Fallot tetralojili gebe sezeryan operasyonuna alındı. Sorunsuz bir şekilde epidural anestezi uygulandı. Hastanın vital bul...

Single crystals of the title compound, C(10)H(13)OS(+)·Br(-), were obtained from ethyl acetate/ethyl ether after reaction of acetophenone with hydro-bromic acid and dimethyl-sulfoxide. The carbonyl group is almost coplanar with the neighbouring phenyl ring [O-C-C-C = 178.9 (2)°]. The sulfanium group shows a trigonal-pyramidal geometry at the S atom. The crystal structure is stabil-ized by C-H⋯B...
