    Notes: Abstract From a comparison of phytosterol and triterpenoid patterns of severalSymphytum officinale cytotypes,S. asperum and their interspecific hybrids,S. ×uplandicum, which were obtained from thin layer chromatography and gaschromatography (also in combination with mass spectrometry), the hybrid character of the latter taxon is clearly shown. The specific value of the triterpenoid isobauerenol as a chemotaxonomical marker within this group is discussed in some detail.

    Notes: Summary In a cytophysiological study it was investigated whether in juvenile trout gonadal steroids stimulate the gonadotropic (GTH)-cells directly or indirectly via the brain. Pituitaries of donor animals were transplanted into the caudal musculature of testosterone-treated and non-testosterone-treated host fish. Testosterone treatment caused an increase in GTH-content in the in situ pituitaries and in the grafts. Accordingly, the gonadotrops displayed ultrastructural changes such as the appearance of well-developed Golgi systems and large globules. The stimulation of the morphological development of gonadotrops and of synthesis and storage of GTH in the allografted pituitaries indicates that testosterone affects the GTH-cells directly. In untreated juvenile trout the gonadotropin content of the pituitary and the gonadotropin concentration in the plasma vary with the time of year. This variation and the role of testosterone and gonadotropin-releasing hormone on the release of GTH are discussed.

    Hindered internal rotations in Van der Waals molecules and molecular crystals (1983)

    Notes: The quantum dynamical behavior of the Van der Waals molecule (N2)2 and that of the ordered α and γ phases of solid N2 have recently been calculated, starting from the same ab initio N2—N2 potential. By interpreting the results of these calculations we try to improve our understanding of the libration/internal rotation motions of the N2 monomers and the orientational order-disorder (α-β) phase transition. Some new results are presented and further (mean-field and libron-model) calculations are proposed which assess explicitly the intermolecular pair correlation effects caused by the anisotropic interaction potential.

    Chemical treatment of membranes of a polymer blend: Mechanism of the reaction of hypochlorite with poly(vinyl pyrrolidone) (1995)

    Topics: Chemistry and Pharmacology
    Notes: Sodium hypochlorite solutions are used to treat membranes prepared from a polymeric blend containing poly(vinyl pyrrolidone) (PVP) to increase their water permeability. Sodium hypochlorite affects the membrane material in such a way that PVP is selectively removed from the membrane matrix. The mechanism of the reaction between hypochlorite and PVP is investigated by several chemical analysis techniques of the reaction products. Strong indications are found that the reaction involves chain scission of PVP according to a radical mechanism. © 1995 John Wiley & Sons, Inc.

    Description / Table of Contents: Bestimmung der Spannungstensoren in dünnen, texturierten Kupferschichten mittels Röntgenbeugung bei streifendem EinfallIonenplattierte Kupferschichten wurden mittels Röntgenbeugung hinsichtlich Texturen und Eigenspannungen untersucht. Die vollständigen Orientierungsverteilungsfunktionen wurden bestimmt und scharfe (111)-Fasertexturen gefunden. Die Messung der Dehnungen erfolgte unter streifendem Strahleinfall. Zur Berechnung der Spannungstensoren wurden sowohl texturgewichtete elastische Moduln als auch texturunabhängige elastische Moduln verwendet. Die Bedeutung der Texturmessung für die Spannungstensorbestimmung wird diskutiert. Die gefundenen Spannungen können als thermisch verursacht verstanden werden.
    Notes: Ion-platted thin copper films were examined for residual stresses and texture by X-ray diffraction. The complete orientation distribution functions were determined and sharp (111)-fibre textures were found. The strains were measured by grazing incidence diffraction. The stress tensors were calculated using both texture-weighted elastic compliances and texture-independent X-ray elastic constants. The importance of the texture measurement for the stress tensor determination is discussed. The found stresses can be interpreted as thermally induced.

The procedure also gives the thermal strain. As application examples, the lattice constants of thin aluminium and copper films deposited by ion-platting are evaluated from grazing incidence diffraction data.

    Notes: The on-line coupling of a liquid-liquid extraction system with capillary gas chromatography using atomic emission detection (GC-AED) has been studied. The required large volumes of about 100 μl of an iso-octane solution can be introduced into the GC-AED system by using the AED solvent vent and a solvent vapor exit in front of the capillary analytical column. Test solutions containing several pesticides were detected using the carbon, chlorine, nitrogen and sulfur channels. Analyte detectability (in concentration units) was improved significantly and low concentractions of the test compounds could be determined (1-5 ng/ml). Aqueous samples were on-line extracted and analyzed. The precision of the large-volume injection itself as well as the total extraction-GC-AED system was satisfactory (RSD of ca. 2 and 4%, respectively). As a real-life application, several ground water samples were screened.

    Description / Table of Contents: Corrosion inspection in aircraft constructionThe inspections required on an aircraft during its operational phase are determined largely by the materials and constructions used. Practical experience has shown that corrosion can generally not be prevented on metallic aircraft structures, even if the surface protection systems have been chosen with great care. Constructions and materials used on aircraft and the result types of corrosion are described and the inspection concept is explained on the basis of this. Finally, typical inspection tasks are presented and the measurement results obtained with different NDT methods are presented and discussed.
    Notes: Die erforderlichen Inspektionen an einem Flugzeug in der Nutzungsphase werden wesentlich durch die verwendeten Werkstoffe und Bauweisen bestimmt. Die praktischen Erfahrungen zeigen, daß an metallischen Leichtbaustrukturen Korrosion generell nicht zu verhindern ist, auch bei sorgfältigster Auswahl der Oberflächenschutzsysteme, Luftfahrtspezifische Bauweisen und Werkstoffe und daraus resultierende Korrosionsarten werden vorgestellt. Darauf aufbauend wird das Inspektionskonzept erläutert. Anschließend werden typische Inspektionsaufgaben gezeigt und die Meßergebnisse mit verschiedenen zerstörungsfreien Prüfverfahren dargestellt und diskutiert.
