The investigations presented below were originally planned on the background of the DARWIN mission. The demand for improved fibre coupling efficiency yet is a general one for applications that cannot cope with the 20% loss of power upon coupling into

For the DARWIN mission the extremely low planet signal levels require an optical instrument design with utmost efficiency to guarantee the required science performance. By shaping the transverse amplitude and phase distributions of the receive beams,

The non-finiteness of the mod-p Schur multiplier of a finitely generated group G with trivial center implies the existence of uncountably many non-residually finite, non-isomorphic central extension groups with kernel C p (see Thm. A). This phenomeno

The microwave plasma surface modification of silicone elastomer with allylamine was studied to improve the biocompatibility of the material. An effort was made to clarify the relationships among plasma conditions and surface chemical composition, phy

Albrecht, W.; Santoso, F.; Luetzow, K.; Weigel, T.; Schomaecker, R.; Lendlein, A.: Preparation of aminated microfiltration membranes by degradable functionalization using plain PEI membranes with various morphologies. In: Journal of Membrane Science. Vol. 292 (2007) 1-2, 145-157. (DOI: 10.1016/j.memsci.2007.01.027)
The work describes the functionalization of microporous poly(ether imide) membranes with ultrafiltration separation profile by degradative functionalization using a two-step treatment process, which leads to strongly aminated membranes with microfilt

The work refers to the hydrophilization of microporous poly(ether imide) (PEI) membranes by coating with brominated poly(vinylpyrrolidone) (BrPVP). The PEI microporous membranes were first aminated with poly(ethylene imine) (Pei) and then coated with

In this note we analyse the analogy betweenm-potent andp-central restricted Lie algebras andp-groups. For restricted Lie algebras the notion ofm-potency has stronger implications than forp-groups (Theorem A). Every finite-dimensional restricted Lie a

It is shown that for the restricted Zassenhaus algebra \({\mathfrak{W} = \mathfrak{W}(1; n)}\), n > 1, defined over an algebraically closed field \({\mathbb{F}}\) of characteristic 2, any projective indecomposable restricted \({\mathfrak{W}}\) -modul

Apheresis is an emerging technique to separate blood components from whole blood or plasma to remove pathologically elevated levels of proteins or toxins. Advantageously, the realization of apheresis by chromatographic techniques allows a selective o
