Nécrose digitale révélant une vascularite rhumatoïde

La vascularite rhumatoïde constitue une manifestation rare < 1% et grave de la PR. Il s'agit d'une vascularite nécrosante des vaisseaux de petit calibre. Les signes habituels sont une vascularite cutanée et une multinévrite .Nous rapportons une nouvelle observation. Patient âgé de 69 ans, tabagique à 50 PA sans antécédents particuliers, consulte pour une polyarthrite touchant les petites et gro...

Neumann Comparison Results in Cylindrical Do- mains

We consider the question: To what extend does the Weyl function (i.e., the abstract Dirichlet-to-Neumann map) see the same singularities as the resolvent of some restriction of the maximal operator. The proper, so-called detectable, subspace will be introduced and analyzed for particular examples, such as, Schrodinger operators, Hain–Lust operators, and (if time permits), the Friedrichs model o...

Mains Signal Propagation through Distribution Systems

This paper looks at a power quality problem termed “Racing Clocks” caused by the amplification of ripple frequency signals in distribution networks. A study of this problem has been undertaken on two 22kV feeder systems within the Sydney area. These two particular feeder systems were chosen as they have caused problems in the past. The purpose of this study was to determine whether the problem ...
