    Description: During the cruises No 17 and 22 of the German research vessel „Meteor“, 45 water samples were taken at 4 stations in the central part of the Mediterranean Sea. Mass spectrometrical analyses showed that systematic, but time variable changes of the oxygen isotope ratios occur. Deep water samples (T〉 500 m) have a ± constant isotopic composition of d18O = +1.79‰ (SMOW) and a Chlorinity of 21.399‰. These data are discussed with respect to paleotemperature determinations.

    The Inhibition by Cytokinin of Auxin-Promoted Elongation in Excised Soybean Hypocotyl (1973)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 29 (1973), S. 0 
    Details
    ISSN: 1399-3054
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: The experiments characterize the inhibition by kinetin of auxin-promoted elongation in excised hypocotyl sections of 3-day soybean seedlings (Glycine max cv. Hawkeye 63). It was found that concentrations of kinetin above 4.2 μM did not further inhibit auxin-promoted elongation. Kinetin is as potent an inhibitor of elongation as actinomycin D or cycloheximide. Tissue incubated for 3 or 5 h in the absence of auxin or cytokinin would, upon addition of auxin, exhibit a new growth rate similar to that of tissue grown in auxin for the entire incubation period. Similarly, tissue grown for 3 and 5 h in the presence of auxin would revert to the control rate of elongation upon addition of kinetin. A 10 to 30 min preincubation in kinetin yielded the tissue incapable, for the ensuing 6 h, of increasing its rate of elongation in response to auxin. Zeatin and isopentenyladenine were more potent than kinetin and benzyladenine in the inhibition of elongation. Levels of ethylene produced in the presence of auxin plus cytokinin indicated that it was not involved in this auxin-cytokinin interaction. Kinetin by itself did not promote elongation; nor did it enhance auxin-promoted elongation at low auxin concentrations.

    Slime of Myxococcus virescens (1973)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 28 (1973), S. 0 
    Details

    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: The slime excreted by two strains of Myxococcus virescens during growth in liquid casitone medium was studied. Strain S1H, unable to grow in dispersion, excreted slime during growth later than strain D11, which grows in dispersion. Slime was precipitated from the cell-free culture solution with ethanol and the crude precipitate fractionately dissolved using first pH 5,4 and then pH 9.0 for the remainder of the precipitate. Comparatively more material from strain S1H than from strain D11 belonged to the pH 9.0 fraction. The fractions thus obtained were dialyzed and then lyophilized.The composition of the slime preparations varied with the density of the harvested cultures. The slime fraction dissolved at low pH contained 12–18 % (w/w) Folin reactive material, 2–4% lipid and 5–30% anthrone positive material (glucose equivalents). The fraction soluble at pH 9.0 was richer in Folin positive material. About 25% of the proteolytic activity in the culture solution was recovered in the slime preparations. No DNA was detected in the slime, unless the cultures were harvested daring the phase of decline.The high polymers of the slime were separated from material of low molecular weight and coprecipitated media constituents by gel filtration on Sepharose 2B. The relative amount of the high polymers increased during growth, although they seemed to be degraded in the culture during the phase of decline. The polymer had a molecular weight of about 20 million. In most preparations: it was Folin positive.

    Sauerstoff-Isotopenuntersuchungen an Mineralen eines metamorphen Profils der Hohen Tauern, Österreich (1973)

    Notes: Abstract Oxygen isotope analyses on minerals of a metamorphic profile from Hohe Tauern, Austria indicate that the oxygen isotopes of the coexisting minerals quartz, garnet, and biotite have been reequilibrated during alpidic metamorphism. The K/Ar-ages of these biotites are in the range of 20–30 my. Metamorphic temperatures can be calculated from the quartz-biotite and quartz-garnet isotopic fractionations. The metamorphic temperature in the northern part of the region under investigation is 440° C and increases in direction to Tauernhauptkamm to about 600° C. Indicated by petrographic investigations, two samples from this area show no remarkable metamorphic influence. K/Ar-determinations on hornblendes and biotites yielded variscan ages. The isotopic temperatures of these samples, calculated by the oxygen isotope fractionations of quartz-biotite, quartz-magnetite, and feldspar-magnetite are equal within the limits of instrumental error and represent the crystallisation temperature of a granodioritic magma of 660–670° C.

    Korrosion und Korrosionsschutz in der Lebensmittelindustrie (1973)

    Description / Table of Contents: Corrosion and corrosion protection in the food industriesThe corrosion of equipment and packaging materials being contacted with food products can result in undesirable alterations of aspect and flavour and in serious cases may give rise to intoxication. Corrosion protection must therefore consider the material to be processed as well as the material of construction. Machinery for processing food products are mostly made of stainless steel which should have a certain molybdenum content to possess sufficient pitting resistance in salt solutions. Aluminium can be used in many instances, provided the particular medium contains neither halides nor bases. Plastic coatings are used increasingly in recent time. In such cases, however, one has to consider, in addition to the corrosion resistance of the materials, the danger of migration of certain ingredients such as plastifier or stabilizers. On the product side one may rely on the inhibiting efficiency of certain constituents, e. g. gelatine.
    Notes: Die Korrosion der Anlagen und Verpackungen, die mit Lebensmitteln in Berührung kommen, kann zu unerwünschten Veränderungen des Aussehens und des Geschmacks und in ernsten Fällen sogar zu Vergiftungen führen. Beim Korrosionsschutz muß man daher sowohl vom Material als auch won den Lebensmitteln her ausgehen. Die Maschinen, die mit Lebensmitteln in Berührung kommen, werden meist aus nichtrostendem Stahl gefertigt, vorzugsweise mit einem gewissen Molybdängehalt, um ausreichende Beständigkeit gegen Lochfraß in Salzlösungen zu gewährleisten. Aluminium kann in zahlreichen Fällen verwendet werden, sofern das jeweilige Medium weder Halogenide noch Basen enthält. In neuerer Zeit verwendet man zunehmend Kunststoffüberzüge. Dabei ist jedoch nicht nur die Korrosionsbeständigkeit dieser Materialien zu berücksichtigen, sondern ebenso die Gefahr der Migration von Bestandteilen (z. B. Weichmacher, Stabilisatoren) aus dem Kunststoff. Produktseitig kann man berücksichtigen, daß manche Bestandteile (z. B. Gelatine) inhibierend wirken.
