Erfahrungen, Orte, Aufenthalte und die Sorge um das Selbst

This article deals with Paul Celans relation to Europe and his version of the 'souci de soi' (Foucault).

Die Konzentration. Zur Bewegung des dichterischen Sprechens in der Poetik Paul Celans

This article demonstrates the mouvement of poetic speech in Celan's poetics at the exemple of one poem, thus stressing the significance of the poetic form.

Zur Poetik Paul Celans: Gedicht und Mensch - Die Arbeit am Sinn

This publication summarises my PhD on Paul Celans poetics, focussing on the constitution of meaning and establishing it as a poetological anthropology.

Die Ungewissheit der Natur. Zur Dichtung Michael Donhausers und Hans-Ulrich Treichels

This article analyses the idea and role of nature in the poetics of two contemporary German poets, Donhauser and Treichel.

3D die shape optimisation for net-shape forging of aerofoil blades

This paper reports on work in developing a finite element (FE) based die shape optimisation for net-shape forging of 3D aerofoil blades for aeroengine applications. Quantitative representations of aerofoil forging tolerances were established to provide a correlation between conventional dimensional and shape specifications in forging production and those quantified in FE simulation. A new direct compensation method was proposed, employing variable weighting factors to minimise the total forging tolerances in forging optimisation computations. A surface approximation using a B-spline surface was also developed to ensure improved die surface quality for die shape representation and design. For a Ni-alloy blade test case, substantial reduction in dimensional and shape tolerances was achieved using the developed die shape optimisation system.

CASTING SOLVENT CONTROLLED-RELEASE OF CHLORHEXIDINE FROM ETHYLCELLULOSE FILMS PREPARED BY SOLVENT EVAPORATION

Chlorhexidine release from ethylcellulose films east from solvents of different dichloromethane/ethanol compositions was studied. Release rate was proportional to the square root of time. Increased ethanol content within the casting solvent significantly enhanced release rate. Release rate and cumulative mass released at different time periods (5, 10, 15 and 25 days) were proportional to the solubility parameter of the casting solvent.
