    Notes: An analysis of the coherent states for the noncompact supergroup Osp(2/2N,R) is presented. In contrast to Osp(1/2N,R), both typical and atypical representations have to be considered. The measure of integration, in general, for Osp(2/2N,R) coherent states is calculated; it is then used to construct the decomposition of unity for the special case of Osp(2/2,R). It is found, however, that the typical and atypical representations of Osp(2/2,R) have to be treated separately. It is verified that the coherent states for Osp(2/2,R) are "closest to classical'' in the sense of Perelomov.

    Notes: Some physically realizable positive discrete series representations of the noncompact orthosymplectic superalgebra Osp(4/2,R) are considered. The decomposition of these Osp(4/2,R) representations on reduction to Sp(2,R)×SO(4) is studied in detail, and the corresponding state vectors are explicitly constructed by acting with the generators on a general lowest weight state. Some examples are given to illustrate these results for particular single-particle spaces.

    Notes: Coherent states for the harmonic oscillator representations of the noncompact supergroup Osp(1/2N,R) are introduced and the invariant integration measure is calculated by studying transformation properties of supercoset variables. The generalized Bogoliubov transformation for mixed systems of bosons and fermions is also obtained. An example for the simple harmonic oscillator is given.

    Notes: [Auszug] Vega, the second brightest star in the northern hemisphere, serves as a primary spectral type standard. Although its spectrum is dominated by broad hydrogen lines, the narrower lines of the heavy elements suggested slow to moderate rotation, giving confidence that the ground-based calibration ...

    Notes: Abstract Theβ-ray spectrum of Cs137 has been measured with an iron-free spectrometer. The energy of the soft component was found to beE 0=514±2 keV. The parameterk of the hard-component shape factorC 2VA (2) (W)=q 2+kp 2 was determined to bek=0.015±0.004. Theβ intensities amount to 6.5% (hard component) and 93.5% (soft component). TheK conversion coefficient of the isomeric transition was measured to beα K=0.093±0.003, in excellent agreement withSliv's theoretical value.

    Notes: Abstract In the decay Eu152→Gd152 fiveβ(circularly polarizedγ) correlations have been measured (Table). The Fermi matrix element of the 3−–3− β transition is small or vanishing. The levels of 344 and 755 keV (I=2+ and 4+, respectively) seem to be collective states.

    Notes: Summary The blood pressure is not disturbed by a local injection of norepinephrine into the hypothalamus, but the excitability of vasopressor centres is affected. Often, the excitability of these centres is decreased; sometimes, it is increased, and, more rarely, it is first potentiated and then inhibited. Epinephrine has the same action, but dopamine is less potent; isoprenaline produces both facilitation and inhibition of these centres, but the facilitating effect is more frequent than with norepinephrine.

    Description / Table of Contents: Zusammenfassung Zwei innerhalb eines Jahres sezierte Fälle von plötzlichem Tod bei elektrischer Dauerstimulation des Herzens durch implantierte Schrittmacher gaben zu der Überlegung Anlaß, wie häufig mit Komplikationen und Spättodesfällen bei solchen Patienten gerechnet werden muß, da dies für die Ausübung spezieller Berufe und insbesondere für die aktive Teilnahme am Straßenverkehr von Bedeutung erschien. Eine Zusammenstellung mehrerer Statistiken mit insgesamt 1341 Behandlungsfällen zeigte, daß Reoperationen infolge von Störungen unterschiedlicher Art in einem großen Teil der Fälle notwendig wurden. Spättodesfälle traten 97–105mal auf 691–969 Patienten auf. In nur 2% waren technische Störungen die Ursache. Auf Grund der plötzlichen Spättodesfälle und der häufig außerhalb der Klinik auftretenden Komplikationen, welche durch den Stress des Straßenverkehrs u. U. begünstigt werden, erscheinen elektrisch dauerstimulierte Patienten für bestimmte Berufe mit Verantwortung für Menschenleben und insbesondere für die aktive Teilnahme am Straßenverkehr ungeeignet.
    Notes: Summary Two cases of sudden death of individuals with cardiac pacemakers were autopsied within a one year period. Speculations regarding reintegration of such patients into certain professions and particularly their ability to participate in road traffic gave rise to the current report. A survey of several statistical evaluations comprising 1341 patients with pacemakers indicated the necessity of repeated surgical intervention because of various failures of stimulation in a large number of cases. Delayed deaths occurred 97–105 times in 691–969 patients. In only 2% of these deaths technical failure was the cause. In consideration of the suddenness with which late complications occur and their aggravation by stress associated with road traffic it appears that patients with pacemakers are unsuitable for certain professions involving the lives of others and should not be granted driving permits.

    Description / Table of Contents: Zusammenfassung An 105 Individuen, 61 männlichen und 44 weiblichen, wird die Behauptung eines Geschlechtsdimorphismus hinsichtlich der Höhe und Größe der Processus mastoidei statistisch nachgeprüft. Für die mediale und laterale Fortsatzhöhe lassen sich keine signifikanten Mittelwertsdifferenzen aufzeigen. Zudem ist die Varianz der Kollektive so groß, daß der Proc. mastoid. als Identifikationsmerkmal ausscheidet. Die gefundene Mittelwertsdifferenz der Größe der Fortsätze, hier durch die äußere Fläche ausgedrückt, läßt sich statistisch eindeutig sichern. Dies entspräche der Vorstellung einer Kausalbeziehung zwischen Ausbildung und Insertion der seitlichen Halsmuskulatur einerseits und Größe bzw. Volumen der Fortsätze andererseits.
    Notes: Summary The supposition regarding sex-linked differences in height and surface area of the mastoid process was tested in 105 human skulls, 61 of which were male and 44 were female. There was no statistically significant difference noted in the mean values of the lateral and medial measurements of the processes from both sexes. Some significance, however, was noted in the measurement of the surface area. This may be associated with the insertion of stronger lateral neck-musculature, as is isually the case in males.
