    Description / Table of Contents: Resumé Le ferrocyanure de potassium trihydraté, K4Fe(CN)6·3H2O, a été chauffé en présence d'oxygÊne dans un Derivatograph, dans des conditions bien déterminées de masse et de vitesse de chauffage. Le chauffage a été interrompu à diverses températures et les spectres Mössbauer ainsi que les diffractogrammes de rayons X ont été enregistrés aprÊs trempe du matériau à la température ambiante. On a étudié de cette faÇon le déroulement de la réaction; on décrit les avantages et les inconvénients de chacune de ces techniques. On a pu déceler la présence de K4Fe(CN)6,α-Fe2O3, Fe3O4 Fe3C, Fe, FeO, KFeO2,Β-FeOOH, KOCN, K2CO3 et KCN aux différentes étapes du traitement thermique.
    Abstract: Zusammenfassung Kaliumhexacyanoferrat(II)trihydrat, K4[Fe(CN)6.3H2O wurde unter kontrollierten Bedingungen in einem Derivatographen in Gegenwart von Sauerstoff erhitzt. Das Aufheizen wurde bei verschiedenen Temperaturen gestoppt und Mössbauer-Spektren, sowie Röntgendiffraktogramme aufgenommen. Der Reaktionsweg wurde auf diese Weise untersucht und die Vor- und Nachteile jeder der Techniken beschrieben. Bei den verschiedenen Stufen des thermischen Vorganges konnten K4[Fe(CN)6],α-Fe2O3, Fe3O4, Fe3C, Fe, FeO, KFeO2,Β-FeOOH, KOCN, K2CO3 und KCN nachgewiesen werden.
    Notes: Abstract Potassium hexacyanoferrate(II) trihydrate, K4Fe(CN)6·3H2O, was heated under controlled conditions of mass and rate in a derivatograph in the presence of oxygen. The heating was stopped at different temperatures and Mössbauer spectra and X-ray diffractograms were taken on the quenched material at room temperature. The reaction pathway was studied in this way and the advantages and drawbacks of each of the techniques are described. At different stages of the thermal process we were able to show the presence of K4Fe(CN)6,α-Fe2O3, Fe3O4, Fe3C, Fe, FeO, KFeO2,Β-FeOOH, KOCN, K2CO3 and KCN.

    Notes: Summary Linkage data of the four gene markers Pi, Gm, GLO, and HLA exclude Gm and Pi gene assignment to the short arm of chromosome 6. The findings, however, do not disprove the following gene order: HLA-GLO-centromere-Gm-Pi.

    Description / Table of Contents: Summary Based on the definition of dynamic inventory models with demand distributions depending on the state of a Markov chain the structure of optimal ordering policies is developed.
    Notes: Zusammenfassung Nach der Definition von dynamischen Lagerhaltungsmodellen, in denen der Bedarf vom Zustand einer Markov-Kette abhängt, wird gezeigt, welche Struktur die unter den Modellprämissen optimale Bestellpolitik hat.
