In patients with insulin-dependent diabetes mellitus (IDDM), microalbuminuria is a predictor of widespread severe microangiopathy and macroangiopathy. Patients with microalbuminuria show generalized dysfunction of the vascular endothelium, but it is [...]

Composites consisting of polymer matrix materials and natural or synthetic layered minerals e.g. clays were prepared by using special compatibilizing agents between these two intrinsically non-miscible components. Block or graft copolymers combining one part of the polymer that is identically and/or completely miscible with the organic polymer and another part that is compatible with the natural mineral are applied to act as compatibilizer. The interaction between the first part of the compatibilizer is preferentially an ionic interaction or an interaction via hydrogen bonds. This interaction leads to a separation of the mineral into single sheets and/or small clusters containing approximately 2–10 sheets and a subsequent homogeneous incorporation of these clusters into the polymer matrix material.

Let  be a smooth complex vector bundle over a compact complex manifold M. The complex gauge group  of  is a non-normable complex Fréchet Lie group which acts smoothly on the affine Fréchet space C" of all partial (0, 1)-connections in . The paper establishes a structural result for the isotropies of this action. Specifically, via methods involving the C∞-topology of the gauge group, the isotropies are shown to be finite dimensional closed embedded complex Lie subgroups of . As an application, a new proof of an earlier result of Morimoto on the finite dimensionality of the group of holomorphic bundle automorphisms of a holomorphic vector bundle is given. The new proof uncovers additional information, namely, that this group is naturally realized as an extension of a closed Lie subgroup of the holomorphic transformations of the base M by the isotropy of the given ∂-operator of the bundle.Copyright 1993, 1999 Academic Press
