Verwirklichende Raume - Poetik und Raumkonzeption bei Paul Celan und Martin Buber

This article with the conception of space in Paul Celan's poetics, comparing it to Martin Buber's and developing a notion of 'realisation', important to both Celan and Buber. Partant du concept du fantastique en tant qu'espace dans laquelle les phénomènes sont véritablement perçus au lieu de simplement se dérouler, l'article montre comment la rupture avec la réalité accoutumée peut mener à une sensation intense de l'être. Chez Martin Buber se trouve la description d'un telle espace, où l'unité est créée à partir de la polarité de tout ce qui est. Le poème peut représenter un exemple d'un tel espace « réalisant ». La conception de l'espace chez Buber est démontrée en dialogue avec le poème STEHEN de Paul Celan, afin de montrer comment le monde réifié est « réalisé » par la poésie. Ainsi sont mis en valeur le rapport mutuel et le lien indispensable entre réalités sociales et la réalité du non-espace.

The Langmuir probe as a diagnostic of the electron component within low temperature laser ablated plasma plumes

A Langmuir probe has been used as a diagnostic of the temporally evolving electron component within a laser ablated Cu plasma expanding into vacuum, for an incident laser power density on target similar to that used for the pulsed laser deposition of thin films. Electron temperature data were obtained from the retarding region of the probe current/voltage (I/V) characteristic, which was also used to calculate an associated electron number density. Additionally, electron number density data were obtained from the saturation electron current region of the probe (I/V) characteristic. Electron number density data, extracted by the two different techniques, were observed to show the same temporal form, with measured absolute values agreeing to within a factor of 2. The Langmuir probe, in the saturation current region, has been shown for the first time to be a convenient diagnostic of the electron component within relatively low temperature laser ablated plasma plumes.

Narrative on the Net:Bill and his hyper- lives, loves and texts

Narrative, by its very nature, is changing as a consequence of internet developments. Hypertexts are, for example, changing not just the way in which we disseminate information, but also the ways in which we write, speak and think. In this paper a narrative approach is taken to assess a case study of a person’s extensive home site on the web. Bill maintains an extensive web site documenting his life with Parkinson’s Disease, his love for running and all matters relating to the island of Montserrat in the Eastern Caribbean. Bill’s Parkinson’s Disease hypertext diary forms the focus of this case study of a life spent on-line. Though set up just as a diary about this progressively degenerative disease, because of its hypertextual qualities, this paper argues that it is through the diary that Bill comes to produce and sustain - to narrate - his identity. This paper thus contributes to the position that though hypertext encourages the construction of fragmented and false identity narratives, it is also a medium for sustaining linear and coherent representations of self-identity.

Stereotactic radiosurgery for arteriovenous malformations, Part 1:management of Spetzler-Martin Grade I and II arteriovenous malformations

The aim of this paper was to define the outcomes and risks of stereotactic radiosurgery (SRS) for Spetzler-Martin Grade I and II arteriovenous malformations (AVMs).

Preparation of Dess-Martin periodinane - The role of the morphology of 1-hydroxy-1,2-benziodoxol-3(1H)-one 1-oxide precursor

1-Hydroxy-1,2-benziodoxol-3(1H)-one I-oxide prepared by oxidation of o-iodobenzoic acid with potassium bromate forms either a microcrystalline powder, a macrocrystalline material, or a mixture of both forms. This difference in physical form is the source of the difficulty in reproducibly converting 1-hydroxy-1,2-benziodoxol-3(1H)-one 1-oxide to the corresponding I-triacetoxy derivative. A simple method is given for conversion of crystalline 1-hydroxy-1,2-benziodoxol-3(1H)-one 1-oxide to the more reactive powder form, The microcrystalline powder and macrocrystalline material are characterised by X-ray diffraction.
