    Comparative rheology of nucleated and non-nucleated red blood cells (1981)
    Springer
    Pflügers Archiv 390 (1981), S. 283-287 
    Details
    ISSN: 1432-2013
    Keywords: Nucleated erythrocytes ; Blood rheology ; Viscosity ; Hematocrit ; Capillary circulation

    Topics: Medicine
    Notes: Abstract The flow properties of nucleated avian (duck) red cell suspensions were determined in narrow glass capillaries (internal diameter 5–11 μm) perfused at constant pressure. Measurements were carried out of cellular and suspending fluid flow velocity and dynamic (tube) hematocrit. Comparison with previous measurements on human erythrocyte suspensions showed that the dynamic hematocrit reduction (Fahraeus effect) of avian cell suspensions was significantly more sensitive to changes of hematocrit than observed on the human cells. It was in addition found that the Fahraeus effect is the dominating phenomenon determining the viscosity of the nucleated cell suspensions, in contrast to suspensions of non-nucleated human red cells. Furthermore, the apparent viscosity of the nucleated cell suspensions is significantly higher than that of human blood at equal capillary diameter and tube hematocrit. In the living capillary bed of birds, the unfavourable rheological properties of the nucleated red cells could be compensated for by a low capillary hematocrit and/or a higher capillary density compared to mammalian species.

    Zur Kristallstruktur der Orthoferrite der Seltenen Erden. III. Strukturuntersuchung am TmFeO3 (1968)
    Weinheim : Wiley-Blackwell
    Zeitschrift für anorganische Chemie 356 (1968), S. 163-171

    Description / Table of Contents: X-ray diffractometer data from powdered thulium orthoferrite, TmFeO3, were used for the determination of the crystal structure by least squares methods. The data were corrected for impurity phases and for anomalous dispersion. Precise lattice constants were determined by calibration with admixed high purity silicon powder.
    Notes: Röntgenpulverdiagramme liefern Daten zur Strukturbestimmung des Thuliumorthoferrits. Aus den Integralintensitäten der Reflexe werden nach Berücksichtigung von Fremdphasenüberlagerungen die Koordinaten der Ionen in der Elementarzelle durch Ausgleichsrechnung bestimmt. Die genauen Gitterkonstanten werden durch Vermessung mit Referenzlinien von zugemischtem reinstem Silicium ermittelt.

    Description / Table of Contents: The crystal structures of orthorhombic selenates MSeO4 (M — Mn, Co, Ni) have been refined by least square methods from X-ray and neutron diffraction powder data.The metal atoms are octahedrally surrounded by oxygen at an average distance of 2.20 Å. The mean distance in the SeO4 tetrahedron is 1.65 Å.
    Notes: Aus Intensitäten von Pulverdiagrammen (Röntgen- und Neutronenbeugung) wurden die Kristallstrukturen der orthorhombischen Selenate MSeO4 (M — Mn, Co, Ni) durch Ausgleichsrechnung verfeinert. In diesen Verbindungen ist das Selen tetraedrisch von Sauerstoff umgeben; der mittlere Selen-Sauerstoff-Abstand beträgt 1,65 Å. Die Metallatome haben sechs Sauerstoffatome in oktaedrischer Anordnung als nächste Nachbarn; der mittlere Abstand zwischen Metall und Sauerstoff beträgt 2,20 Å.
