    Notizen: Measurement of diode photocurrent represents a new method for obtaining extended x-ray absorption fine structure (EXAFS) information specific to the junction region of a diode. EXAFS measurements at Ga and As K edges of an aluminum-on-GaAs Schottky diode have been used to demonstrate this new technique. The spectra observed in the diode current arise mainly from x-ray absorption events within 2 μm of the diode junction, i.e., within a minority carrier diffusion length of the approximately 600-A(ring)-wide depletion region. The diode current EXAFS are consistent with EXAFS obtained from fluorescence measurements.

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung Leberblutungen nach spitz-scharfer oder stumpfer Oberbauchtraumatisation sind keine Seltenheit. Von besonderem Interesse sind jedoch atraumatische Leberblutungen, wenn bei strafrechtlichen Ermittlungen tödliche Leberblutungen als einzige oder konkurrierende Todesursache diskutiert werden müssen. Mit Hilfe der Ergebnisse von Tierversuchen an Kaninchen konnte gezeigt werden, daß unter spezifischen enzymatischen Stoffwechselbedingungen innerhalb weniger Tage Blutungen einzig in der Leber entstehen. Atraumatische Leberblutungen mit Rhexis-Kavernen können den Folgezustand einer Traumatisation vortäuschen und, unter forensischen Aspekten falsch interpretiert, Analß für ein Fehlurteil sein.
    Notizen: Summary Hepatic hemorrhages are not unusual after sharp or blunt abdominal traumata. They are of particular interest when deadly hepatic hemorrhages are under discussion as the single or contributory cause of death in forensic investigations, for instance after reanimation or acts of violence. The test results in rabbits demonstrate that artificial and specific enzyme-assimilation conditions can cause atraumatic hepatic hemorrhages in only a few days. With and without concomitant injuries, liver bleeding may have an atraumatic genesis. An additional human case report shows the possibility of confusion with atraumatic rhexis hemorrhage in the liver.

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung In Fortführung früherer experimenteller, postmortaler Schädelbruchverletzungen von Säuglingen nach Stürzen aus 82 cm Höhe wurden weitere 35 Sturzversuche durchgeführt, so daß insgesamt Ergebnisse von 50 Fällen vorliegen. Bei je 5 Sturzversuchen auf harten Untergrund — (Steinkachelboden, Teppichboden und Linol-Schaumstoff) — waren in allen Fällen Kalottenfrakturen entstanden. Bei den 35 Sturzvorgängen auf weich gepolsterten Untergrund — (Schaumstoffmatte, Kamelhaardecke) — traten bei 5 Fällen gleichartige Frakturen auf, die im Os parietale lokalisiert waren. In dieser Region besteht bis zum späten Säuglingsalter wegen primärer Einschichtigkeit der Ossifikation, noch fehlender Diploe und Vaskularisation eine besondere Prädilektionszone für Bruchverletzungen nach stumpfer Gewalt, insbesondere bei Sturz auf den Kopf. Diese Untersuchungsergebnisse haben somit bestätigt, daß nach angeblichen Sturzvorgängen aus Wickeltischhöhe die Annahme der Unversehrtheit des Säuglingsschädels nicht berechtig ist.
    Notizen: Summary Following previous experiments on postmortem skull fractures of infants, falls from 82-cm heights onto stone (A), carpet (B) and foam-backed linoleum (C), 35 further falling tests were carried out onto softly cushioned ground. In 10 cases a 2-cm thick foam rubber mat (D) was chosen and in 25 further cases a double-folded (8-cm-thick) camel hair blanket (E). Hence the results of altogether 50 tests could be evaluated. In test groups A–C on a relatively hard surface, skull fractures of the parietale were observed in every case; in test group D this fracture was seen in one case and in test group E in four cases. Measurements along the fracture fissures showed bone thicknesses of 0.1–0.4 mm. The fracture injuries originated in paper-thin single-layer bone areas without diploe, which can also be considered the preferred regions for skull fractures of older infants following falls from low heights. These results indicate that it is no longer possible to assume that the skull of infants is not damaged after falls from table height.

    Notizen: Abstract Ultrastructural evidence is presented of a chromatophoresystem in the zooxanthellae containing hermatypic, deep-water coral Leptoseris fragilis (Milne Edwards and Haime). It consists of multilobed cells which mainly occupy the intercellular space of the oral gastrodermis. The cellular processes are filled with electron-dense granules up to 1-μm-long and 0.5-μm-wide. Within the cytoplasm an elaborate system of microtubules is established. The ramifications of the pigment cells, containing the pigment granules, form a dense and nearly continuous layer close to the overlying zooxanthellae. It is speculated that host pigments may transform the violet portion of the incident light into longer wavelengths, thus increasing the photosynthetic efficiency of the zooxanthellae.

    Notizen: Summary A sensitive assay for thiamine suitable for clinical use has been developed. It is based on precolumn oxidation of thiamine to thiochrome followed by HPLC-separation and fluorescence detection. The assay is applicable to various biological materials, including human plasma. The minimum amount detectable was 5 fmol, minimum plasma concentration 0.5 nmol/l and minimum sample volume 0.3 ml plasma. Each chromatographic run took 3 min. Inter- and intra-assay relative standard deviations (RSD) were 8.3% and 6.3%, respectively, at a stock plasma concentration of 10.8 nmol/l. At 38.8 nmol/l, interassay RSD was reduced to 3.4%. The recovery of 5 nmol/l added thiamine was 102 (SD±17)%, that of 30 nmol/l was 94±5%. Plasma levels in 91 volunteers ranged from 6.6 to 43 nmol/l, showing a log normal distribution with a median of 11.6 nmol/l. Thiamine kinetics were studied in plasma and urine from 8 men after intravenous and oral doses of 50, 100 and 200 mg thiamine hydrochloride. In all individuals, nonlinear renal elimination kinetics were demonstrated by plotting the fractional amount of thiamine excreted unchanged in urine against the corresponding area under the plasma concentration — time curve.

    Notizen: Abstract The surfaces of Pt-45Pd-10Rh foils oxidized over the range 875–1075 K in a 20% O2-Ar mixture at atmospheric pressure were examined by Auger electron, X-ray photoelectron, and Raman spectroscopy. The composition of the oxide formed on the surface was found to vary with temperature from predominantly PdO at 875 K to PdRhO2 at 1075 K. Only a few atomic percent Pt was observed, present in both the metallic and (apparently) +1 oxidation states at 875 K and in the metallic state at 1075 K. The formation of PdRhO2 (and no Rh2O3) at 1075 K was found to persist upon reoxidation following a low-temperature reduction cycle in which the increased Rh concentration on the surface was retained. An oxidation-induced Rh enrichment of the surface of the alloy foil beyond 50 at. % does not appear likely within the temperature/pressure regime investigated.

    Notizen: Abstract The surfaces of air-oxidized Pd-15Rh alloys have been examined by X-ray photoelectron spectroscopy (XPS) and by Raman spectroscopy. The XPS results indicate that the near-surface region of samples oxidized in the temperature range 1075 to 1125 K contains Pd in both the +2 and +1 oxidation states and Rh in the +3 oxidation state. The ratio of Pd (I) to Rh (III) is found to be 1∶1. Raman spectra confirm that two Pd-containing phases, PdO and PdRhO2, are present in the near-surface region and eliminate the possibility that Rh2O3 is present. Also, a resonant Raman effect is observed in anhydrous PdO for exciting wavelengths in the vicinity of 500 nm.
