A design of a flexible, light-weighted sieve electrode with integrated cables for interfacing regenerating nerves has been developed using micromachining technologies. The authors used polyimide as substrate and insulation layers and platinum as electrode metallization. The materials showed no cytotoxic effects in biocompatibility testing. In first chronic experiments on the sciatic nerve of rats, the authors received good regeneration, a functional reinervation, and no mechanical traumatization of the nerve caused by the microsystem due to the flexible materials.
The effects of highly dispersed (≤ 0.1mg/cm2) noble metal catalysts (e.g. Pd, Pt, Ir and Ru) on the electrochemical performance of screen printed La0.84Sr0.16MnO3 cathodes was investigated. At typical operating condi...
The effects of highly dispersed (≤ 0.1mg/cm2) noble metal catalysts (e.g. Pd, Pt, Ir and Ru) on the electrochemical performance of screen printed La0.84Sr0.16MnO3 cathodes was investigated. At typical operating conditions (e.g. T=1273K, η= −0.1V), the current density in presence of palladium is increased by about one order of magnitude as compared to the current density obtained with pure La0.84Sr0.16MnO3 cathodes. At the same time, the apparent activation energy of the oxygen reduction reaction is decreased from ≈ 2eV (without catalyst) to ≈ 1eV (with Pd).
What is the relation between the average level of complexity that characterizes a product's technology, and the degree of diversity of that technology across rival firms? Evolutionary theories of innovation and te...

Lisp applications need to show a reasonable cost-benefit relationship between the offered expressiveness and their demand for storage and run-time. Drawbacks in efficiency, apparent in Lisp as a dynamically typed prog...

Kernel/2r is a software infrastructure that provides the integration platform for the construction of distributed process-oriented multi-user/multi-role systems. Kernel/2r includes different process engines that enable the enactment of formally defined process models, thus assisting users in staying in line with procedures and regulations required by law or by the organization or ISO 9000 quality standards, for instance. The authors demonstrate the appropriateness of Kernel/2r as a basis for the construction of application systems in the engineering domain as well as in the commercial domain by discussing the IRIN Software Factory and the OTIS on-line ticket vending system.< >

Noting that software reuse depends on the availability of engineering concepts for its support, the author introduces some of those engineering concepts and two derived notions: uniformity and invariance. He argues that both of these notions play an important role in the industrialization of the underlying engineering concepts.< >
