    Notes: Zusammenfassung 1. Es wird gezeigt, daß die Unregelmäßigkeiten bei der Filtration von der gleichen Art sind wie die Anomalien beim Fließen der kolloiden Lösungen. 2. Die Erscheinung des Filtereffektes ist daher wesensverwandt mit den bekannten Erscheinungen der Rheopexie (Fließverfestigung) und Thixotropie (Fließverflüssigung). 3. Der Unterschied ist nur ein gradueller, indem sich diese Anomalien, entsprechend der geringen Dimension molekulardisperser kinetischer Einheiten, erst bei viel dünneren Schichten bemerkbar machen. 4. Auf Grund der Vorstellung, daß jedes rheonome (fließgesetzliche) System aus kleinen skleronomen (starrgesetzlichen) Systemen (Molekülen, Mizellen usw.) aufgebaut ist, werden die Rechengrundlagen diskutiert und einige Diagramme als Ausführungsbeispiele diskutiert. 5. Es werden einige experimentelle Ergebnisse zum Filtereffekt mitgeteilt und einige praktisch wichtige Konsequenzen für die Filtration gegeben, die sich in manchen Industrien vielfach bewährten und daher Beachtung auch für andersartige Verwendungszwecke verdienen.

    Notes: Abstract Dipeptidase A (Dip-A), a new peptidase locus in Drosophila melanogaster, is located on the second chromosome at map position 55.2 and in the 41A-B; 42A2-3 interval in the salivary gland chromosomes. Three alleles are reported. In the Carpenter, North Carolina population the allele frequencies are: Dip-A 6 (fastest)=0.064; Dip-A 4 (intermediate)=0.920; and Dip-A 2 (slowest)=0.015.

    Genetic and cytogenetic studies of four glycolytic enzymes in Drosophila melanogaster: Aldolase, triosephosphate isomerase, 3-phosphoglycerate kinase, and phosphoglucomutase (1979)
    Springer
    Biochemical genetics 17 (1979), S. 769-783 
    Details
    ISSN: 1573-4927
    Keywords: Drosophila ; aldolase ; triosephosphate isomerase ; glycolysis

    Notes: Abstract Four glycolytic enzymes in Drosophila melanogaster have been genetically and/or cytogenetically mapped. The structural gene for aldolase (Ald) has been genetically mapped to 3-91.5 and cytogenetically localized to 97A-B. Tpi, the structural gene for triosephosphate isomerase, has been genetically mapped to 3-101.3 and cytogenetically localized to 99B-E. Utilizing closer-flanking markers than the previous mapping, Pgk, the structural gene for 3-phosphoglycerate kinase, has been mapped to 2-5.9; cytogenetically it was found to lie in the interval between 22D and 23E3. The cytogenetic location of Pgm, the structural gene for phosphoglucomutase which has been located genetically at 3-43.4, was determined to be in 72D1-5.

    Genetic and cytogenetic studies of the malate dehydrogenases of Drosophila melanogaster (1979)
    Springer

    ISSN: 1573-4927
    Keywords: malate dehydrogenase ; cytoplasmic ; mitochondrial ; cytogenetic ; Drosophila
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Genetic and cytogenetic locations of the structural genes for the NAD-dependent malate dehydrogenases have been studied. The mitochondrial form (mMDH) is coded for by a gene (Mdh) found at 62.6 on the third chromosome and included in Df(3R)P14, which includes 90C2–91A3 in the salivary gland chromosomes. Based on its inclusion within several J (Jammed; 2–41.0) deficiencies, the structural gene (cMdh) for the cytoplasmic form (cMDH) was determined to lie in region 31B-E, confirming the earlier finding of Grell. Flies lacking any cMDH activity (cMdhn-γ10069/ Df(2L)J-der-27) were both viable and fertile.

    Description / Table of Contents: The well-known pendulum apparatus for the testing of paints (DIN 53157) has been provided with a heating unit and used for testing polymer materials.The obtained value (PW) turns out to be easily determinable and appropriate for the characterization of viscoelastic properties of polymers as a function of temperature. The results are discussed in connection with those obtained with the torsional pendulum.This paper is intended to stimulate further measurements, discussions and above all to bring up new interpretation possibilities of the results.
    Notes: Das nach DIN 53157 bekannte und der Lackprüfung dienende Pendelgerät wurde für diese Messungen mit einer Heizung versehen und für Untersuchungen an Kunststoffen eingesetzt. Die erhaltene Meßgröße, der Pendelwert, erweist sich als eine geeignete und leicht bestimmbare Größe zur Charakterisierung verschiedener Kunststofftypen und erlaubt eine Beschreibung und Erklärung ihres visko-elastischen Verhaltens in Abhängigkeit von der Temperatur. Die Ergebnisse werden auch im Vergleich mit den Ergebnissen aus freien Torsionsschwingungen diskutiert. Weitere Messungen, Diskussionen und vor allem eine Erweiterung der Interpretation der Ergebnisse sollen durch diese Arbeit angeregt werden.

    Notes: Mode of action and characterization of multifunctional automotive exhaust catalysts. Because of the pending reduction in permissible concentration of toxic components in automotive exhausts the catalysts presently available will have to be replaced by more efficient systems. For these “second generation” catalysts multifunctional platinum/rhodium based catalysts are in the course of development, with provision being made for control of the fuel/air mixture. The new catalysts destroy both NOx as well as carbon monoxide and hydrocarbons and are effective in the neighbourhood of the stoichiometric composition of the fuel/air mixture. The mode of action of the new “three-way” catalysts is described in detail and the present trends in development are outlined.
