    Notes: Abstract If an electrically conducting medium (e.g. a dusty plasma) rotates around a gravitating central body, which possesses an axisymmetric dipole field, the medium is supported to two-thirds by the centrifugal force and to one-third by electromagnetic forces under the condition that the magnetic field is strong enough to controll the motion. If the electromagnetic forces disappear — e.g. by a de-ionisation of the dusty plasma — the medium will fall down to two-thirds of its original central distance. The result of this process will be a ‘cosmogonic shadow effect’ which is described in some detail. The Voyager 1/Saturn results demonstrate that the macro-structure of the Saturnian ring system can be explained as a result of this effect working at the formation of the system. The agreement between the theoretical results and the observations is better than a few percent. A similar analysis of the asteroidal belt shows that its macro-structure can also be explained by the cosmogonic shadow effect. The agreement between theory and observations is perhaps even better than in the Saturnian ring system. The observational results demonstrate that during their formation both the Saturnian ring and the asteroidal belt passed a plasma state dominated by electromagnetic effects.

    Description / Table of Contents: Zusammenfassung Vor dem Hintergrund der geschichtlichen und demographischen Entwicklung Brasiliens wird die derzeitige medizinische Versorgung dargestellt und Probleme der psychiatrischen Bedarfsanalyse und -planung diskutiert. Die Situation in Brasilien ist durch einen Mangel an psychiatrischen Versorgungseinrichtungen und epidemiologischen Daten gekennzeichnet. Eine kostengünstige und rasche Verbesserung könnte durch ein vorgeschlagenes Stufenprogramm erreicht werden: Einrichtung von psychiatrischen sowie kinder- und jugendpsychiatrischen Abteilungen an Allgemeinkrankenhäusern, stufenweiser Aufbau eines extramuralen Versorgungssystems, Gesetze zur Erleichterung der Rehabilitation und die Bildung einer Enquete-Kommission zwecks Bestandsaufnahme und Planung des Soll-Zustandes für die psychiatrische Versorgung Brasiliens.
    Notes: Summary The current state of mental health care in Brazil, and the problems of estimating needs in the population and of planning psychiatric services, are reviewed against the national historical, sociodemographic and medical background. The situation in Brazil is characterized by a shortage of psychiatric care agencies, as well as of the statistical and epidemiological data required for planning purposes. The following steps are proposed as a programme of action to bring about a rapid and relatively economic improvement in this situation: (1) establishment of psychiatric and child psychiatric departments in general hospitals; (2) establishment of out-patient, day-patient and rehabilitation facilities in the local communities; (3) legislation to abolish discriminatory practices against former psychiatric patients, and to extend health insurance cover to after-care and rehabilitation services; (4) setting-up of a national commission to enquire into the situation of mental health care, to formulate plans for a comprehensive, community-based mental health service and to promote research in this field.

    Description / Table of Contents: Zusammenfassung DC-Remissions-Eichkurven für definierte Konzentrationsbereiche lassen sich mittels der Gleichung: ln S=a · F b (bzw. ln S=a · H b) weitgehend linearisieren. Dabei bedeuten F = Peakflächen, H = Peakhöhen und S = passende Skalenteile für die Substanzmenge. Im Rahmen des DC-Methodenfehlers werden gute Übereinstimmungen zwischen Rechner-Geraden und Meßdaten erhalten, wie an 10 Beispielen von Arzneistoffen gezeigt wird. Für enge Eichbereiche genügt meist schon eine Kurvenanpassung mit einer Potenzfunktion ohne Logarithmierung der S-Werte. Eine Arbeitstechnik, die zu guten Ergebnissen führt, wird beschrieben.
    Notes: Summary TLC reflectance calibration curves for defined concentration ranges can be nearly linearized by the equation: ln S=a · F b (respectively: In S=a · H b) where F means the peak area, H the peak height and S adequate scale figures for the concentration. As shown on 10 examples of drugs, a good correlation of the calculator fit with the measured data is obtained within the range of the TLC error. For narrow calibration ranges usually a power curve fit without forming the logarithms of the S values is sufficient. A working technique, leading to good results, is described.
