    Notes: Abstract In voltage clamp experiments on myelinated nerve fibres the time resolution of the current measurement is limited by the low-pass characteristics of the internodes. We increased the corner frequency of the current passing internode by grounding one half of this internode externally. Using a simplified equivalent circuit we calculated an increase in the bandwidth of the internode by a factor of about 6. Consequently, the peak value of the recorded capacity current increased while its duration was considerably shortened.

    Antitumor properties of organometallic metallocene complexes of tin and germanium (1988)

    Notes: Summary The antitumor activity of the four metallocene compounds decaphenylstannocene [η5-(C6H5)5C5]2Sn(II), decabenzylstannocene [η5-(C6H5CH2)5C5]2Sn(II), decaphenylgermanocene [η5-(C6H5)5C5]2Ge(II), and decabenzylgermanocene [η5-(C6H5CH2)5C5]2Ge(II), containing the main group IV elements tin or germanium as the central metal atom and two pentasubstituted cyclopentadienyl ring ligands in sandwich arrangement, were tested against Ehrlich ascites tumor in female CF1 mice. The complexes caused cure rates of 40% to 90% of the animals treated over rather broad dose ranges. With both germanocene complexes, no strong dose-activity relationship was manifest. The toxicity of all four metallocenes was low, the LD10 values of both stannocenes being 460 and 500 mg/kg, and those of both germanocenes higher than 700 mg/kg. Regarding the isolated pentasubstituted cyclopentadiene ligands (C6H5)5C5H and (C6H5CH2)5C5H, these also exhibited antitumor activity which was less pronounced than that of the metal-containing sandwich complexes. Decasubstituted stannocene and germanocene compounds represent a new type of non-platinum group metal antitumor agents structurally differing from known inorganic and organometallic cytostatics.

    Über die bevorzugte kristallographische orientierung der einzelkristalle in natürlichen faserhalitaggregaten (1976)

    Description / Table of Contents: Summary The orientations of the crystallites in a fibrous halite were determined using an X-ray universal stage method in which for each individual grain the Laue-diagrams of the three symmetry axes, made visible by an image intensifier, were set at the center. The results are presented in an equal-area net using the poles of the corresponding grain's sections in a spherical triangle with the normals to (001), (011) and (111) as corner points. Studies on a thin section perpendicular to the fiber direction revealed a two-fold axis approximately along the fiber direction for about a third of the crystallites. This is qualitatively what is expected from halite vectorial growth rates. The results of sections parallel to the fiber axis are not so clear but do show orientation effects.
    Notes: Zusammenfassung Die Orientierung der Kristallite eines Faserhalites wurde mit einer Röntgen-U-Tisch-Methode bestimmt, indem für jedes Korn die drei Symmetrieachsen des durch einen Bildverstärker sichtbar gemachten Laue-Bildes zentral gestellt wurden. Die Darstellung der Ergebnisse erfolgte in einer flächentreuen Projektion durch Eintragung der Pole der Kornschnittflächen im entsprechenden Präparat in einem sphärischen Dreieck mit den Durchstoßpunkten der Senkrechten auf (001), (011) und (111) als Eckpunkten. Aus der Bearbeitung eines Schnittes senkrecht zur Faserrichtung ergibt sich, daß etwa ein Drittel der Kristallite eine zweizählige Achse nahe zur Faserrichtung hat; das entspricht qualitativ den Erwartungen aus den vektoriellen Wachstumsgeschwindigkeiten beim Halit. Die Ergebnisse aus Schnitten parallel zur Faserachse sind nicht so klar zu interpretieren, jedoch zeigen sich auch hier Orientierungseffekte.

    Description / Table of Contents: Summary The fabric of an oriented halite rock sample from Niedersachsen-Riedel pit near Wathlingen (Niedersachsen, BRD) was determined by fixing the orientation of 540 grains using a four circle X-ray universal stage. The statistical evaluation leads to weak maxima of the poles of the fourfold axis and shows that the {100} faces lie — more often than purely statistically — parallel to the three macroscopic partition planesL, S andQ which are oriented approximately perpendicular to each other. — Further investigations would be necessary for a genetic interpretation of natural halite fabrics.
    Notes: Zusammenfassung Das Korngefüge einer orientiert entnommenen Halit-Gesteinsprobe aus der Grube Niedersachsen-Riedel bei Wathlingen (Niedersachsen, BRD) wurde durch Festlegung der räumlichen Orientierung von 540 Einzelkörnern mit Hilfe eines vierachsigen Röntgen-U-Tisches bestimmt. Die statistische Auswertung führt zu schwach ausgeprägten Maxima der Pole der vierzähligen Achsen und zeigt, daß die {100}-Flächenlagen merklich häufiger als rein statistisch in den drei annähernd senkrecht aufeinander stehenden makroskopischen TeilungsflächenL, S undQ liegen. — Für eine allgemeinere genetische Erklärung eines natürlichen Halit-Gefüges wären noch weitere Untersuchungen notwendig.
