    Notes: The exoerythrocytic forms of Plasmodium gallinaceum in thin sections of infected tissue cultures have been examined with the electron microscope. It was seen that important changes occur in the fine structure of the parasite during the various phases of the cycle. The cytoplasm of the merozoites at the beginning and at the end of each cycle shows a great electron density due to a fine granulation. Larger granules are found at one pole of the parasite. The merozoites have a large nucleus in the center, and an oval body of great electron density at one pole, the significance of which is unknown. Short canaliculi can also be seen in the cytoplasm, but no mitochondria have been found.The cytoplasm of the schizonts shows a low electron density. It contains small particles scattered irregularly throughout its whole mass. The nuclei are not well defined; the oval body observed in the merozoites apparently has disappeared. Short canaliculi are present everywhere; however, mitochondria could not be identified with certainty.In the final phase of the cycle, in the rosette formations, the cytoplasm assumes again the fine granular structure. The future merozoites are grouped around a cytoplasmic core, with which they are directly connected. The whole segmenter is situated in a vacuole formation. In cross sections of the merozoites an opening in the central pole has been observed.

    Notes: In order to study the blepharoplast-kinetoplast region in the adult form of Schizotrypanum cruzi thin sections of this form, obtained in tissue cultures, have been examined with the electron microscope. It has been seen that the kinetoplast is contained in a large spherical, vacuole-like space, in hich its osmiophilic mass is more dispersed than in the leishmania and crithidia forms, where it is contained in a rectangular, almost linear space. The basal body of the flagellum has been found at the margin of the vacuole, although separated from it. A group of striae in parallel array has been found with regularity in all the trypanosome forms, similar to the structures of the parabasal body in other protozoa, or to the Golgi apparatus of metazoan cells. The significance of this structure for the parasite is discussed.

    Notes: [Auszug] A second group of proteins was also found which possessed a mobility on filter paper similar to, but not identical with, that of albumin. They migrate at the same rate as the slow portion of the albumin and in starch gel can be separated from albumin only in a discontinuous system of buffers. These ...

    Untersuchungen über die Verwendung einer Pseudomonas spec. zum Nachweis von Thioaminosäuren in chromatographisch reiner Glutaminsäure (1960)

    Notes: Zusammenfassung Eine Pseudomonas spec., deren Abhängigkeit von verwertbaren Nicht-Sulfat- oder Sulfit-Schwefelverbindungen bei einer Symbiosestudie festgestellt wurde, zeigt ein auffälliges Washstum durch chromatographisch reine Glutaminsäure. Es wurde festgestellt, daß dieses Wachstum zum überwiegenden Teil auf Verunreinigungen der Glutaminsäure mit Thioaminosäuren zurückzuführen ist. Mit diesem Keim läßt sich übersichtsmäßig der Gehalt der Glutaminsäure an Gesamt-Thioaminosäuren ungefähr bestimmen. Die Reinsubstanz der jeweiligen Thioaminosäure bewirkt eine deutlich lineare Abhängigkeit des Wachstums von der Aminosäure-Konzentration. Als Reinsubstanz kann nicht nur die l-Form, sondern auch die d-Form bei Methionin, sowie neben Cystin auch Cystein bestimmt werden.

    Der Synergismus von Schwermetallionen (Cu++, Cd++, Pb++, Hg++) und kolloidalem Schwefel bei der fungiciden Wirkung auf Conidien von Fusarium decemcellulare (1960)

    Notes: Zusammenfassung Kombinationen von Cadmium-, Kupfer-, Blei- und Quecksilbersalzen mit kolloidalem Schwefel wirken stark synergistisch. Eine blaue Kupfer-verbindung, Bleisulfid, Cadmiumsulfid und eine sich mit Lauge grau-grün färbende Quecksilberverbindung, welche dabei in den Conidien auftraten, konnte nicht in ursächlichen Zusammenhang mit der synergistischen Wirkung gebracht werden. Die nähere Untersuchung des Synergismus zwischen Kupfer und Schwefel zeigte eine schnellere toxische Wirkung des Gemisches, eine Störung des Schwefelreduktionsvermögens der Conidien durch Kupfer und eine starke Förderung der Kupferaufnahme durch den Schwefel. Kolloidaler Schwefel fördert auch die Aufnahme des Bleis und des Cadmiums in die Conidien, aber nicht die des Quecksilbers.

    Notes: Zusammenfassung Die affine Lösung vonNeuringer undMcIlroy [1] für die ebene, laminare Staupunktströmung einer elektrisch leitenden Flüssigkeit in einem magnetichen Feld wird auf den rotationssymmetrischen Fall erweitert. Die gemäss dem Jouleschen Gesetz umgesetzte Wärme sowie die Wärmezufuhr durch Reibung werden dabei ohne Vernachlässigung berücksichtigt. Die Randbedingungen werden neu formuliert, und Lösungen werden erhalten in der Gestalt von gewöhnlichen Differentialgleichungen, die numerisch integriert werden. Die Grössenordnung der auftretenden Parameter wird abgeschätzt in Fällen, welche physikalisches Interesse haben. In den meisten Fällen ist es möglich, eine Grenzschicht-Annäherung einzuführen. Die Resultate hängen dann im wesentlichen nur von einem einzigen Parameter ab. Die Geschwindigkeitsverteilung, das magnetische Feld und der Wärmeübergang an der Körperoberfläche werden berechnet.

    Die Harmonischen der Rotationsenergie bei der Schubkurbel und verwandte Fourier-Reihen (1960)

    Notes: Summary The rotational energy of a link in a mechanism is proportional to the square of its angular velocity. This ‘square’, in contrast to the angular velocity itself, can be expanded into a Fourier series, having finite values for its coefficients. The problem is solved by splitting it into partial fractions, leading to the harmonic analysis of the slotted lever mechanism. Further related series are given at the end.
