Das Tris(pentafluorethyl)silanid-Anion addiert an Carbonylverbindungen Ph(R)CO (R=Ph, H), CS2 und CO2, was die Isolierung neuartiger negativ geladener Spezies wie [Si(C2F5)3(η2-OC(R)Ph)]− [Si(C2F5)3(η2-CS2)]− [Si(C2F5)3(η2-CO3)]− ermöglicht. Details zu den Reaktionen werden im Forschungsartikel von Berthold Hoge et al. auf S. 12231 beschrieben. Poröse Materialien Fibröse Proteine Supramolekular...

Isolates of mesenchymal stromal cells (MSCs) contain a mixed cell population of stem cells, multipotent and unipotent progenitors, and differentiated cells. It is speculated that the useful subpopulation for tissue engineering and cell therapy will be the multipotent progenitor cells or the stem cells. The colony forming unit-fibroblast (CFU-F) assay is an in vitro assay for clonogenicity, whic...

The minimal bactericidal concentrations of N-formimidoyl thienamycin (N-f-thienamycin) against 21 strains of enterococci isolated from patients with infective endocarditis were determined by macro- and microdilution methods. By a macrodilution technique with the minimal bactericidal concentration defined as greater than or equal to 99.9% killing of an initial inoculum, all 21 strains of enteroc...

7 Acknowledgments We want to thank specially Stefan Mießbach for numerous contributions in proving the convergence properties of the net dynamic and for advice concerning the " cornered rat " example. We are very grateful to Ingrid Gabler for supplying the experimental data for this same example. 6.3 Convergence of the dynamic We show now the local convergence of the dynamic defined by the MF e...

I. Motivation. Let H be a Hilbert space and f : H → R a C-functional. To study critical points of f in the framework of the classical approaches (Morse Theory [39], Ljusternik–Schnirelman theory [40], etc.) one needs to assume, in particular, that f satisfies the Palais–Smale condition (in short, PS-condition): any sequence {xn} ⊂ H with {f(xn)} bounded and ∇f(xn) → 0 contains a convergent subs...

Let F be a set of ordered patterns, i.e., graphs whose vertices are linearly ordered. An F-free ordering of the vertices of a graph H is a linear ordering of V (H) such that none of the patterns in F occurs as an induced ordered subgraph. We denote by Ord(F) the decision problem asking whether an input graph admits an F-free ordering; we also use Ord(F) to denote the class of graphs that do adm...

Missu brevis F dur op. 21 Hud 279 (1885) Fibich vytvořil během dvouleté tvůrčí krize. Skladba se dočkala mnoha provedení v českých a moravských chrámech zůstala součástí jejich repertoáru až do čtyřicátých let 20. století. V kompozici nalezneme vlivy kompoziční techniky renesanční vokální polyfonie, basso continuo, techniku harmonizace protestantského chorálu, ale...
