    Notizen: Many crystals produce a diffuse scattering of X-rays which is localized in a series of relplanes. It is shown that the corresponding linear disorder in the crystal may have various origins. In silicon, the scattering is due to thermal vibrations and is well explained by the elastic properties of the crystal. In neutron irradiated quartz the radiation damage is responsible for the major part of the scattering. The case of BaTiO3 and KNbO3 is discussed in detail. A linear disorder is proposed which accounts better for the different distributions of the scattering in the 4 allotropic phases than the alternative explanation of the soft mode. In spite of some neutron inelastic scattering results it is not yet possible to distinguish between static and dynamic disorder.

    Notizen: A qualitative description of the X-ray diffuse scattering from NaNbO3 single crystals as a function of temperature up to 800°C is given. Two types of distinct diffuse scattering where observed in {100} reciprocal planes and on (100) reciprocal axes. While the diffuse scattering in reciprocal planes shows no critical behaviour at the different phase transitions and can be attributed to a `linear disorder' similar to that suggested earlier for KNbO3, the diffuse scattering on reciprocal axes is critical in the vicinity of the 641°C phase transition. The atomic displacements involved with the linear disorder that persists up to 800°C are attributed to the niobium atoms; the critical planar disorder in the cubic phase is attributed to rotations of oxygen octahedra similar to those suggested for SrTiO3 and KMnF3. Both types of disorder exist in the cubic paraelectric phase.

    Notizen: X-ray diffuse scattering from V0.90Nb0.10O2 shows that the metal-to-insulator phase transition which occurs around - 25°C without an overall structural change can be explained by local pairing of the vanadium atoms. This local order, which recalls the low-temperature insulating structure of pure VO2, is two dimensional and occurs in the (110) planes of the average rutile structure with little correlation between successive parallel (110) atomic planes.

    Notizen: From the study of X-ray diffuse scattering diagrams, it has been shown that the diffuse scattering located along three equivalent reciprocal rods (100) in the cubic phase disappears successively at 641, 575 and 520°C. The interpretation is given in terms of planar local order.

    Notizen: Abstract In order to obtain strains of Saccharomycopsis lipolytica impaired in the active transport of l-lysine, mutants resistant to a mixture of l-canavanine, l-4-5-transdehydrolysine and l-S-amino ethylcysteine, taken either all three or two by two, were isolated. These compounds were shown previously to be competitive inhibitors of l-lysine uptake. The resistance patterns and excretion capacity of the mutants were established. All mutants behaved as monogenic. Recombination tests indicated that four genes at least were involved. All mutants were impaired in both high and low affinity l-lysine transport systems. Several hypotheses on the functions of these genes are put forward and discussed.

    Notizen: Summary Reversions of a mutation lye 1.5 blocking the first step of the lysine catabolic pathway were isolated. These reversions mapped inside the LYC1 locus. They exhibited an alteration of the regulation of the lysine pool after nitrogen and phosphorus starvation. This phenomenon did not appear in sexual diploids homozygous for the reversion. Diploids homozygous for the mating type were constructed by protoplast fusion. They displayed a pattern similar to that of the haploids. We conclude that the expression of this mutation is under the control of the physiological state of the mating type.

    Beschreibung / Inhaltsverzeichnis: Résumé La déshydratation du gypse (réaction du typeS→ S′+G oùS′ est un solide non stoechiométrique) est étudiée à l'aide d'un réacteur en lit fluidisé. La forme particuliè re de la courbe isotherme qui traduit, pour le système binaire CaSO4- H2Og, la présence d'un équilibre divariant, permet d'interpréter l'influence de la masse initiale du produit dans le réacteur, du débit de fluidisation et de la température sur cette réaction.
    Kurzfassung: Zusammenfassung Die Dehydratisierung von Gips (eine Reaktion des TypsS→ S′+G, wobeiS′ ein nichtstöchiometrischer Festkörper ist) wurde mit Hilfe eines Fluidbettreaktors untersucht. Die eigenartige Form der Isotherme, welche für das Binärsystem CaSO4- H2Og ein divariantes Gleichgewicht andeutet, gestattet die Deutung des Einflusses der anfänglichen Masse des Produktes im Reaktor, der Leistung der Fiuidisation sowie der Temperatur auf diese Reaktion.
    Notizen: Abstract Dehydration of gypsum (which is anS→ S′+G type reaction whereS′ is a nonstoichiometric solid) was investigated by means of a reactor in a fluidized bed. The special shape of the isothermal curves shows that a divariant equilibrium is present in the case of the CaSO4-H2Og system. One can interpret the influence of the amount of starting material in the reactor, and the effects of fluidization and temperature for this type of reaction.
