    Notes: Dynamical diffraction of thermal neutrons is treated for a plane single-crystal plate of magnetic neutron-absorbing material. It is shown that the results of the theory of dynamical X-ray diffraction can be used in the case of neutron diffraction, when the Fourier transforms of the polarizability are replaced by the Fourier transforms of the interaction potential divided by the kinetic energy of the neutrons. The Fourier transforms of the magnetic part of the interaction potential are calculated expicitly. In order to take the nuclear part of the interaction into account the method of the Fermi pseudopotential is used. The results are applied to the case of symmetrical Bragg reflection. There are two solutions for the intensity of the reflected beam as a function of the angle of neutron incidence, corresponding to the two possible directions of the neutron spin, parallel or antiparallel to the magnetic field in the crystal. It is shown that the positions of the maxima and the widths of the curves illustrating the intensity dependence on the angle of neutron incidence are different for the two possible spin directions and depend on the direction of the magnetization in the crystal. The total intensity of the reflected beam for the diffraction of unpolarized neutrons is obtained by averaging the intensities for the two possible spin directions.

    Description / Table of Contents: Zusammenfassung Unter den Verfahren, die zur Diagnostik des Pankreas-Carcinoms zur Verfügung stehen, kommt der Szintigraphie eine besondere Bedeutung zu. Die Methode basiert auf der Anreicherung einer markierten Aminosäure im Drüsengewebe, es wird also funktionstüchtiges Gewebe dargestellt. Die Diagnose Pankreas-Carcinom ist aus dem szintigraphischen Bild allein nicht zu stellen, weil Funktionsausfälle anderer Genese einen gleichen Befund ergeben können. In diesen Fällen ist die gezielte Eingriffdiagnostik indiziert. Der begrenzte zeitliche und personelle Aufwand sowie die geringe Belastung für den Patienten machen die Pankreasszintigraphie zu einer Methode, die sinnvollerweise-zusammen mit den internistischen Verfahren- am Beginn der diagnostischen Bemühungen stehen sollte.
    Notes: Summary Of the procedures available for diagnosis of pancreatic carcinoma, particular significance can be attributed to scintigraphy. The method is based upon the accumulation of a labeled amino acid in the glandular tissue. The scanning technique delineates functionable tissue. The diagnosis of carcinoma of the pancreas cannot be deduced from the scintigraphic picture alone, however, because functional deficiency of a different origin could result in the same picture. In these cases, carefully planned exploratory surgery is indicated. The limited expense in terms of time and personnel and the modest stress to the patient make pancreatic scintigraphy a method that can reasonably-together with internal procedures-be applied right at the beginning of the process of diagnosis.

    Notes: [Auszug] The experiments were performed on the right pyriformis muscle of Rana temporaria. This muscle is usually innervated by spinal branch IX; it has, however, been observed7 that occasionally the muscle receives additional motor axons from spinal branch VIII. One of these branches, usually IX, was cut ...

    Description / Table of Contents: Summary In 60 children the relationship between facial structures and different types of swallowing was studied. More tongue-thrust swallowers were found in the group with vertical craniofacial growth and there was also a significantly decreased overbite.
    Abstract: Résumé Chez 60 enfants on a étudié la corrélation existant entre le type de déglutition et la structure de la face. La déglutition somatique est plus fréquente avec le type de croissance faciale horizontale et la déglutition viscérale avec le type de croissance verticale. Chez les enfants à type de croissance verticale et présentant une déglutition viscérale, nous avons trouvé une diminution de la supraclusion très significative.
    Notes: Zusammenfassung Die Korrelation zwischen Schluckart und Aufbau des Gesichtsschädels wurde an 60 Kindern untersucht. Die somatische Schluckart ist häufiger beim horizontalen-, die viscerale Schluckart beim vertikalen Wachstumstyp aufgetreten. Bei Kindern mit vertikalem Wachstumstyp und visceraler Schluckart fanden wir einen hochsignifikant verringerten Überbiß.

    Description / Table of Contents: Zusammenfassung In den letzten 11 Jahren wurden 11 Pat. mit einer galligen Peritonitis nach Gallenwegoperationen behandelt. 6 Kranke verstarben. 6mal bestand eine diffuse, 5 mal eine lokale Peritonitis. Nach unserer Erfahrung ist die subhepatische Drainage nach jedem Gallenwegseingriff die beste Prophylaxe. Bei gutem Abfluß über das Drain kann es hierbei noch nach Tagen zu einem spontanen Versiegen des Galleflusses kommen. Bestehen jedoch zusätzlich die Zeichen einer Peritonitis, so muß man unverzüglich laporotomieren und das Leck in den Gallenwegen verschließen. Bei schlechtem Allgemeinzustand genügt hierbei zunächst eine Entleerung und ausreichende Drainage der Bauchhöhle.
    Notes: Summary In 11 years we observed 11 patients with bile peritonitis after operations on the biliary tract. Six of the patients died. There were 6 patients with diffuse and 5 with local peritonitis. According to our experience the subhepatic drain is the best prophylaxis after all operations, even simple cholecystectomy. If there is a good flow of bile through the drain spontaneous occlusion of the leak in the biliary tract can occur even after a few days. If a permanent flow and the clinical symptoms of peritonitis are noted, immediate laparotomy, revision and closure of the leak are necessary. If the patient's condition is poor evacuation and drainage of the abdomen only can be performed initially.

    Description / Table of Contents: Summary 1. Long-term recordings of redox-potential in marine sediments performed under laboratory conditions show that the drift of the measured potential after inserting the electrode cannot be neglected. 2. Cleaning and reinserting an electrode considerably changes the measured potential. This change may reach several hundred mV, depending on the position of the electrode and the composition of the sediment. 3. It takes several days until the potentials observed before cleaning are obtained again. 4. The overall Eh-profile in the sediment column is not changed by successive experiments. An electrode at a certain position in the sediment normally will return to the same potential if enough time is allowed for stabilization. 5. Quick measurements of single Eh-values in systems such as marine sediments must be handled with caution. 6. The measured shape of the redox-profile strongly depends on the time allowed for stabilization. 7. The position of the redox-potential-discontinuity defined as the point of inflection of the curve Eh versus depth seems to be the only meaningful parameter derived from quick measurements.
    Notes: Kurzfassung Die Meßergebnisse von Redoxpotentialen in marinen Sedimenten sind oft schwierig zu interpretieren, weil neben vielen Störungen auch Potentialänderungen nach dem Einbringen der Elektrode in das Sediment auftreten. Zur Quantifizierung dieses Problems wurden Sande aus der Nordadria in Plexiglasrohre gefüllt und Laborversuche unter kontrollierten Bedingungen durchgeführt. Nachdem sich das mit Gold- bzw. Platinelektroden gemessene Redoxpotential stabilisiert hatte, die Elektroden herausgezogen und mechanisch gereinigt waren, konnten deutlich andere Potentiale als vor dem Reinigen festgestellt werden, die erst im Verlauf einiger Tage die alten Marken wieder erreichten. Dabei ändert sich das Eh-Profil in den Sandsäulen selber offensichtlich wohl nicht. Es zeigt sich aber, daß die gemessene Form des Redoxprofils von der Stabilisierungszeit abhängig ist. Durch kurzfristige Messungen kann allerdings die Lage der Redox-Potential-Diskontinuität festgestellt werden.
