    Description / Table of Contents: Summary ESR investigations of lyophilized blood of patients with acute lymphatic leukemia exhibit an increase in spin concentration and an additional peak not present in control samples. This peak disappears almost completely concomittantly with a reduction in spin concentration after treating the patients with prednisolone, vincristine, and doxorubicin or after addition of 5 mM of CuCl2 to blood samples. The results show that the ESR spectra of lyophilized blood samples can be utilized to follow the effect of therapy. Moreover, they suggest that the leukemic blood possesses a high concentration of antioxidants.
    Notes: Zusammenfassung ESR-Untersuchungen an lyophilisiertem Blut von Patienten mit akuter lymphatischer Leukämie zeigten eine Zunahme in der Spinkonzentration. Außerdem trat ein zusätzliches Signal auf, welches in Kontrollproben nicht vorhanden ist. Wenn man die Patienten mit Prednisolen, Vincristin und Doxorubicin behandelt, verschwindet gleichzeitig mit einer Abnahme der Spinkonzentration dieses Signal fast vollständig. Ein ähnlicher Effekt wurde erhalten, wenn entsprechende Blutproben mit 5 mM CuCl2 versetzt wurden. Die Ergebnisse zeigen, daß die ESR-Spektren von lyophilisierten Blutproben als Indikator für den Therapie-Verlauf benutzt werden können. Diese Ergebnisse deuten darüber hinaus darauf hin, daß leukämisches Blut eine hohe Konzentration an Antioxidantien besitzt.

    Notes: Abstract Two effects are considered to influence the time dependence of the transformed volume in a binary alloy: a) the impingement effect (IE), takes into account the mutual impingement of the growing particles and b) the impoverishment effect (PE), which considers the decrease of driving forces and the increase of the diffusion paths in the approximation of an impoverishing matrix. Combining both effects growth equations are obtained analogous toJohnson-Mehl-Avrami only for one-dimensional growth.

    Notes: Abstract The decomposition processes taking place in the Al-4.5 at % Zn-2 to 3 at % Mg alloys were studied during continuous heating by means of electrical resistivity, XSAS and DSC measurements and by TEM investigations. It was found that the room temperature pre-ageing has no significant influence on the processes taking place above 230° C. Several temperature ranges were determined in which the decomposition of the solid solution and/or the transformation of the different particles of the second phases take place by different mechanisms.
