    Description / Table of Contents: Zusammenfassung Die mikrophotometrische Auswertung von Spektren erlaubt über den Vergleich mit den Spektren eines UV-Normales nach Rössler, Krefft und Rüttenauer die spektrale Emission eines Quecksilber-Einspritz-Brenners zu bestimmen. Schon geringe Beimengungen zum in den Kern der Entladung injizierten Quecksilber verändern die spektrale Strahlungsverteilung. Brennt die Entladung mit kathodischem Brennfleckensatz in einer Gasatmosphäre, so liegt in der Wahl dieses Zusatzstoffes eine weitere Möglichkeit, die spektrale Emission des Quecksilber-Einspritz-Brenners zu variieren. Über diese Spektren und ihre Interpretation wird in der vorliegenden Arbeit berichtet.
    Notes: Summary The spectra of the mercury injection lamp can be determined by microphotometric analysis. It is shown that small quantities of additives vary the spectral distribution. This paper presents spectra and their interpretation.

    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.

    Notes: Summary To the creamy-yellow colored bases of the rump feathers ofDucula bicolor adheres lipoid and noncolored powder. It is supposed, that the lipoid contains the creamy colour, which apparently is no carotenoid.

    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.

    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: Zusammenfassung Der Aufbau der Chorda dorsalis wurde bei zwei Tunikaten — Dendrodoa grossularia und Oikopleura dioica — elektronenmikroskopisch untersucht. Die Chorda von Dendrodoa besteht aus einem Strang solider, mit Dottereinschlüssen gefüllter, glykogenreicher Zellen. Sie sind von einer Paserschicht umhüllt, an der die quergestreifte Muskulatur des Schwanzes unmittelbar ansetzt. Die Chorda von Oikopleura besteht aus peripher gelegenen epithelartigen Zellen, die eine mit elastischem Material gefüllte, langgestreckte Vakuole umschließen. Ihr Cytoplasma enthält locker verteilt Golgi-Apparat, glattes und granuliertes endoplasmatisches Reticulum, Mitochondrien vom tubulären Typ und optisch leere Vakuolen. An der Faserhülle der Chorda setzen lateral die beiden Stränge quergestreifter Muskulatur an. Am Schwanz beider Formen werden ventrale und dorsale Flossen auf unterschiedliche Weise ausgebildet.
    Notes: Summary The fine structure of the notochord of two tunicate species — Dendrodoa grossularia and Oikopleura diowa — was investigated with the electron microscope. In Dendrodoa, the notochord consists of a cord of solid glycogen-rich cells, which contain numerous big yolk droplets. These cells, which are otherwise poor in cytoplasmic organelles, are surrounded by a layer of fibrils, to which the muscle cells of the tail are firmly attached. In Oikopleura the notochord consists of peripheral flat epitheliumlike cells, which surround a single central rodlike vacuole filled with elastic material. The cytoplasm of the notochordal cells contains loosely distributed Golgi apparatus, smooth and granulated endoplasmic reticulum, mitochondria of the tubular type and empty-appearing vacuoles. The two muscle tracts of the tail are laterally attached to the fibrous sheath of the notochord. The dorsal and ventral fin of the tail exhibit in both animals a completely different ultrastructure.

    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.
