    Description / Table of Contents: Zusammenfassung Plasma normaler und anämischer Ratten, markiert mit59FeCl3, wurde mit konzentrierten Retikulozyten inkubiert. Die Plasmaclearance von59Fe war signifikant rascher als jene des kalten Eisens. In weiteren Experimenten wurden unterschiedliche Mengen von markiertem und unmarkiertem Plasma derart gemischt, daß das Schlußvolumen, sowie die59Fe-, die56Fe- und die Transferrinkonzentration konstant blieben. Das Ausmaß der Radioeisenaufnahme durch Retikulozyten erwies sich als abhängig von der Zahl der voll-gesättigten Di-59Fe-Transferrinmoleküle. Beide Befunde belegen die Heterogenität des Plasmaeisenpools.
    Notes: Summary Plasma of normal and anaemic rats was labelled with59FeCl3 and incubated with packed reticulocytes. The rate of plasma clearance of59Fe was significantly accelerated compared to that of cold iron. In further experiments varying amounts of labelled and unlabelled plasma were mixed to give identical final volumes,59Fe-,56Fe- and transferrin-concentrations. The amount of radioactivity taken up by cells diminished with decreasing numbers of di-59Fe-transferrin molecules, present in the system. Both findings point to the functional heterogeneity of the plasma iron pool.

    AMOUNTS AND TURNOVER RATES OF BRAIN PROTEINS IN MORPHINE-TOLERANT MICE (1971)

    Notes: Abstract— Mice were injected intracerebrally with radioactive leucine 30 min before decapitation. A double-label technique was used; e.g. [3H]leucine in control, untreated mice and [14C]leucine in morphine-tolerant (dependent) mice. Proteins were extracted sequentially from mouse brain with aqueous buffer, Triton X-100, and sodium lauryl sulphate. Each extract was subjected to electrophoresis on discontinuous, porosity-gradient acrylamide gels. When the protein patterns from untreated, acutely morphinized mice were compared with those from morphine-tolerant (dependent) mice, we observed no differences in the amounts of protein or of radioactivity in any of the 55 discrete bands.

    Notes: Zusammenfassung Die Eisenabgabefähigkeit doppelt beladener Transferrinmoleküle an Retikulozyten, ist jener einfach beladener Moleküle überlegen, und vermindert sich rasch wenn Serum unter physiologischen Bedingungen inkubiert wird. Als Erklärung wird die Neuverteilung von Eisenatomen unter den Transferrinbindungsstellen postuliert.

    Optimal startup control of a jacketed tubular reactor (1971)
    Hoboken, NJ : Wiley-Blackwell

    Notes: The optimal startup policy of a jacketed tubular reactor, in which a first-order, reversible, exothermic reaction takes place, is presented. A distributed maximum principle is presented for determining weak necessary conditions for optimality of a diffusional distributed parameter system. A numerical technique is developed for practical implementation of the distributed maximum principle. This involves the sequential solution of the state and adjoint equations, in conjunction with a functional gradient technique for iteratively improving the control function.
