    Description / Table of Contents: Zusammenfassung Die Schwefelisotopenzusammensetzung von sulfidischen Erzmineralen und Baryten der unterdevonischen schichtgebundenen Bleiglanz-Zinkblende-Baryt-Erzvorkommen des Grazer Paläozoikums (Ostalpen, Österreich) wurde untersucht. Zur Analyse gelangten 64 Proben von etwa 15 Lokalitäten. Die Schwefelisotopenverteilung zeigt Ähnlichkeiten mit anderen an das Devon gebundenen schwerspatführenden Lagerstätten. Die Baryte ergaben 34S-Werte von +23, 1 bis +27, 8‰, die dem Meerwassersulfat devonischen Alters entsprechen. Die untersuchten Galenite variieren von +2, 4 bis +6, 9‰ und die Sphalerite von +3, 3 bis +9, 1‰. Die Werte der Pyrite zeigen einen großen Streubereich (−27, 4 bis +37, 6‰). Eine massive buntmetallarme Pyritvererzung fällt durch sehr schweren Schwefel auf. Späte Mineralisationsphasen der Sulfide tendieren gleichfalls zur Anreicherung des schweren Schwefels.
    Notes: Abstract The sulphur isotope compositions of 64 samples of sulphide minerals and barites from the strata-bound Lower Devonian ore deposits of the Paleozoic Complex of Graz in the Eastern Alps (Austria) have been investigated. The δ 34S-values of galenites and sphalerites show only small variations in the range of +2, 4 up to +6, 9‰ for PbS and +3, 3 up to +9, 1‰ for ZnS indicating abiogenic origin. Later remobilized sulphide minerals show a tendency to heavier sulphur. The deposition of pyrites is influenced partly by bacteriogenic processes (−27, 4 up to +37, 6‰). The enrichment of heavier sulphur characterizes massive pyrite mineralisations being poor on base metals. The sulphur isotope compositions of barites (+23, 1 up to 27, 8‰) correspond to Devonian sea water sulphate. An ore free barite characterized by increased strontium concentration shows heavier sulphur (+29, 6‰) than barites from ore beds.

    Notes: Abstract The Austrian reconnaissance study of stream-sediment composition — more than 30000 clay-fraction samples collected over an area of 40000 km2 — is summarized in an atlas of regional maps that show the distributions of 35 elements. These maps, rich in information, reveal complicated patterns of element abundance that are difficult to compare on more than a small number of maps at one time. In such a study, multivariate procedures such as simultaneous R-Q mode components analysis may be helpful. They can compress a large number of variables into a much smaller number of independent linear combinations. These composite variables may be mapped and relationships sought between them and geological properties. As an example, R-Q mode components analysis is applied here to the Grazer Paläozoikum, a tectonic unit northeast of the city of Graz, which is composed of diverse lithologies and contains many mineral deposits.

    Notes: Abstract  The progress in microfabrication technologies is currently characterized by an increasing number of microproducts and corresponding efforts for cost effective mass fabrication. In this context, the development and utilization of new application specific materials has become one of the key challenges for the commercial production of miniaturized functional units. This applies, in particular, to the LIGA technique, a sequence of process steps combining deep lithography, microelectroforming and micromoulding, which offers an extremely broad spectrum of materials for the generation of ultraprecise three-dimensional microstructures. A wide variety of polymers, metals, metal alloys and ceramic materials are by now accessible for fabricating microdevices. There are practically no major limitations in selecting the desired material properties, e.g. in respect of mechanical stiffness or biocompatibility, optical transparency or magnetic properties, resistance against corrosion or whatever is required by the specific function of a microdevice.

    Notes: Abstract This paper is focused on the development of plastic nano titer plates for applications in high throughput screening (HTS). For screening systems with integrated confocal microscopes plastic chips have been fabricated by injection molding and injection compression molding which contain micro wells with volumes of 0.9 μl and 1.4 μl and bottom plates with thicknesses of 120 μm and 200 μm. In addition, plastic chips with through holes have been joined with 160 μm glass plates by an adhesive printing process. First fluorescence correlation spectroscopy (FCS) measurements show that the plastic plates with glass bottoms are qualified as screening grade FCS nano titer plates.

    Notes: Summary The influence of a benzodiazepine (triazolam) on the body temperature of poor sleepers during nights disturbed by airplane noises has been examined. Subjects were divided into 3 groups each of 8 men. Following a double-blind design, Group A (controls) received a placebo for 6 consecutive nights, Group B received 0.25 mg triazolam, and Group C received 0.5 mg triazolam on nights N3, N4 and N5. On all other nights Group B and C subjects received placebo. For all 3 groups, nights N3 and N5 were disturbed by 32, semi-randomly distributed airplane noises. Air and wall temperatures (To=20°C), and air humidity (Tdp=10°C), were kept constant. Rectal temperature and 4 local skin temperatures were recorded from each subject. Urine samples were collected each morning for measurement of cortisol and catecholamine levels. Noise was found to cause an increase in body heat storage, but only in Group A. Both drug groups showed impairment of body heat balance. The hypothermic action of triazolam could be explained both by a central action of the drug on the thermoregulatory controller and by a peripheral action on blood vessels.
