    Notes: Zusammenfassung und Schlußfolgerung Anhand der vorgestellten Erbegnisse lassen sich für unser Kollektiv folgende Aussagen treffen: 1. Die KathD-Konzentration ist unabhängig von der Mehrzahl der etablierten Prognosefaktoren, so auch vom Nodalstatus. 2. Die KathD-Konzentration korreliert positiv mit der Rezidivwahrscheinlichkeit. 3. Somit kann die Bestimmung der KathD-Konzentationen im Tumorzytosol des primären Mammakarzinoms dazu beitragen, insbesondere aus dem Low-Risk-Kollektiv der nodalnegativen Patientinnen nochmals Untergruppen mit erhöhtem Rezidivrisiko zu selektieren.

    Determination of the gap distribution in YBa2Cu3O7 using a far-infrared reflection-Fabry-Pérot device (1993)
    Springer
    The European physical journal 90 (1993), S. 3-12

    Notes: Abstract This paper reports on far-infrared measurements of YBa2Cu3O7 films oriented with the c-axis perpendicular to the surface, by using a silicon reflection Fabry-Pérot interferometer as a multireflection device. From these we could derive the dielectric function, the refractive index, the field penetration depth and the surface impedance of the material. The one order of magnitude higher sensitivity of the method compared to a direct reflectance measurement allowed to find an almost continuous gap distribution in the 70–215 cm−1 region together with a separate gap at about 330 cm−1. A quasizero gap absorption is found down to 20 cm−1 even at low temperatures (10 K).

    FIR-spectroscopy on iron-doped YBaCuO ceramics: energy gap, phonons and a band at 500 cm−1 (1991)
    Springer
    The European physical journal 83 (1991), S. 1-5 
    Details
    ISSN: 1434-6036
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract We have measured the reflectance of superconducting iron-doped YBaCuO ceramics in the frequency range from 20 to 10000 cm−1 for various temperatures above and belowT c . In these spectra we could directly observe an energy gap. A Kramers-Kronig analysis was performed. We discuss the temperature dependence of two infrared-active phonons and an absorption band located around 500 cm−1.

    Effect of the nitrification inhibitors 1-amidino-2-thiourea and dicyandiamide in combination with urea and ammonium sulfate (1990)

    Notes: Abstract The efficiency of the nitrification inhibitors dicyandiamide (DCD) and 1-amidino-2-thiourea (or guanylthiourea = GTU) in reducing losses from N fertilizers was investigated in two greenhouse experiments where leaching of nitrate-N was induced by percolation at 3 and 5 weeks after fertilization. At an application rate of 10% by weight of fertilizer-N (e.g. 10 kg GTU/ha), GTU in combination with ammonium sulfate (AS) had effects similar to those of DCD (e.g. 15 kg DCD/ha) with regard to nitrate leaching, plant yields and nitrogen uptake. However, in combination with urea (U), GTU was more effective than DCD when applied at the same ratio except with a humic sandy clay soil (pH 7.3, 4.4% organic C), where GTU did not perform as effectively. Nitrate leaching was reduced by as much as 50% using U/GTU instead of U/DCD, and plant yield increased by 30%. At temperatures between 17 and 25°C, the combination U/GTU could protect a high percentage of the nitrogen from being nitrified and leached over a 3 to 5 weeks period. The superiority of GTU over DCD was demonstrated especially in the treatments with 5 weeks of preincubation, despite the considerably lower application rate.

    Increased mechanical fragility and intravascular lysis of erythrocytes in cats fed a propylene glycol-containing diet (1992)

    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract The mechanism responsible for the decreased red blood cell (RBC) lifespan associated with feeding propylene glycol (PG)-containing diets was investigated to understand better how Heinz body-contained RBC are destroyed. Three cats were fed a diet containing 12% PG for 14 days and three other cats served as control. The experimental group developed reticulocytosis and increased Heinz body numbers. Red blood cell membrane immunoglobulih G (IgG) concentration and phagocytosis of RBC by peritoneal macrophages were lower in the PG group compared to the control group suggesting that neither IgG nor non-IgG-mediated phagocytosis was responsible for the RBC destruction. Osmotic fragility, rate of RBC proteolysis and mild mechanical fragility test results were not statistically different from controls. However, when RBC from cats fed PG were exposed to severe mechanical stress, their fragility were increased 2.2–2.8 times. Additionally, haptoglobin concentrations were decreased in the PG group. These data suggest that intravascular lysis may be involved in the pathogenesis of PG-induced RBC destruction.

    Description / Table of Contents: Das in einer früheren Arbeit publizierte kinetisch/strukturelle Modell wird auf den Netzwerkaufbau durch Coreaktion von 2,2-Bis(4-cyanatophenyl)propan mit 2,2-Bis(4-glycidyloxyphenyl) propan in der Schmilze angewendet. Die relativen Geschwindigkeitskonstanten der Hauptreaktionen, die die freien Parameter des Modells darstellen, werden für diesen Fall identifiziert, und die gute Übereinstiummung zwischen Theorie und Experiment wird gezeigt.
    Notes: The previously published kinetical structural model is applied to the network build-up during the coreaction of 2,2-bis(4-cyanatophenyl) propane with 2,2-bis(4-glycidyloxyphenyl) propane in bulk. The relative rate constants of the main reactions, which act as the free parameters of the model, were identified for this case, and the good agreement between theory and experiment is shown.
