    Notes: The fine-focusing capability of a current-carrying, "active" plasma lens has been demonstracted for the first time. A cylindrically symmetric argon discharge plasma pulsed with an oscillating current of over 20 kA in amplitude served as a current conducting medium. With this plasma lens has been demonstrated for the first time. A cylindrically symmetric argon discharge plasma pulsed with an oscillating current of over 20 kA in amplitude served as a current conducting medium. With this plasma lens the diameter of an incident 2.2-GeV gold ion beam from the linear accelerator UNILAC at GSI-Darmstadt was focused from initially 10 to about 0.25 mm, at a focal length of only 140 mm. The gradient of the azimuthal magnetic field exceeded 120 T/m. The striking features of this first-order and strong-focusing plasma lens favor its use as a precise high-gradient focusing device for high-energy charged particles.

    Notes: Abstract A study of prompt neutrino events from 400 GeV protons on a beam-dump is presented. The ratio of electron- to muon-neutrino rates is 0.86±0.14, in agreement withe−μ universality. The anti-neutrino to neutrino flux ratio is $$\bar v_\mu /v_\mu = 0.81 \pm 0.19$$ . The absolute rates and distributions observed are shown to be in quantitative agreement with the known properties of charmedquark production in hadron collisions.

    Description / Table of Contents: Summary This study considers findings of psychological gerontology as particularly important for geriatric rehabilitation research. Its concrete aim was to describe the course and outcome of geriatric rehabilitation based on a wide range of success criteria, to explore the influencing role of age, sex, and diagnosis as well as to describe the variability pattern of success. The data were gathered from a sample of 100 older adults who underwent treatment in a German inpatient rehabilitation unit. Participants were assessed across five measurement occasions by use of a state-of-the-art geriatric assessment and psychological data collection part. The results underline, for one, that significant improvements of functional as well as psychological capacity were obtained. Second, age and sex played practically no role concerning the course of the success criteria, whereas diagnosis revealed some statistically meaningful effects. Third, it was found that the variability of success was characterized by a relatively homogenous pattern of gain with regard to functional criteria; with respect to psychological variables, heterogeneity was more pronounced and some participants show loss as well, a chance for further improvement of the geriatric rehabilitation.
    Notes: Zusammenfassung Diese Arbeit geht von der Notwendigkeit aus, grundlegende Erkenntnisse der psychologischen und sozialwissenschaftlichen Gerontologie stärker als bisher in die empirische Rehabilitationsforschung mit alten Menschen einzubeziehen. Konkretes Ziel war es, den kurz- und langfristigen Verlauf geriatrischer Rehabilitation mit Hilfe eines erweiterten Spektrums von Erfolgsmaßen zu beschreiben, den Einfluß der Variablen Alter, Geschlecht und Diagnose auf den Verlauf zu prüfen, sowie die interindividuelle Variabilität des Erfolges zu beschreiben. Dazu wurden 100 Patienten der stationären geriatrischen Rehabilitation über 5 Meßzeitpunkte hinweg einer eingehenden medizinisch-geriatrischen sowie psychologischen Erhebung unterzogen. Die Ergebnisse zeigen, daß die Rehabilitation sowohl kurz- als auch langfristig gute bis sehr gute Erfolge in geriatrisch-medizinischen und psychosozialen Aspekten der Lebensqualität erbringt. Das Lebensalter und das Geschlecht spielen nahezu keine Rolle im Hinblick auf den Verlauf der Erfolgsmaße, während sich deutliche Diagnoseeffekte nachweisen lassen. Hinsichtlich der Variabilität des Erfolges zeigen sich vergleichsweise homogene Verläufe in bezug auf die medizinisch-geriatrischen Erfolgsmaße mit deutlichen Erfolgen bei nahezu allen Teilnehmern. In bezug auf die psychosozialen Maße sind neben moderater ausfallenden Gewinne bei einigen Personen auch Verluste zu konstatieren, ein Hinweis, die Bemühungen in diesem Bereich zu verstärken.

    Description / Table of Contents: Zusammenfassung Dieser Beitrag nimmt seinen Ausgang davon, daß die Interventionsgerontologie heute ein sehr breites Spektrum an Einflußformen auf normales Altern wie Altern mit Kompetenzeinbußen bereitstellt. Als zweiter Ausgangspunkt wird die These aufgestellt, daß die Interventionsgerontologie in Zukunft in noch stärkerer Weise, als dies bereits heute der Fall ist, Alternsverläufe verändern kann und wird. Im weiteren werden der Stellenwert der interventionsgerontologischen Forschung heute detailliert dargelegt und dabei vor allem die heute existierende Verknüpfung mit grundlagenwissenschaftlichen Befunden, die zugrundeliegende kontextuelle Sicht des Alterns, die interdisziplinäre Orientierung sowie der erreichte Methodenstandard herausgestellt. Sodann wird das in der Zukunft zu erwartende Potential der Interventionsgerontologie an drei Bereichen illustriert: 1. Gesundheit und Alltagskompetenz, 2. Wohnen und 3. Kommunikation.
    Notes: Summary This paper starts with the insight that today's intervention gerontology provides a very broad scope of strategies with impact on the course of normal aging as well as aging with competence losses. Also, it is assumed that this impact of intervention gerontology will grow even further in the future. In the following, current intervention gerontology research is discusses by particularly highlighting its connection with basic gerontology findings, the contextual view of aging, the interdisciplinary orientation, and the methodological standard. With respect to the potential of gero-intervention in the future, three prototypical domains are considered: (1) health and everyday competence, (2) living environments, and (3) communication.

    Notes: Abstract The energy loss of heavy ions with an energy of 1.4 MeV/u in a hydrogen plasma has been measured. A 20 cm longz-pinch has been used as plasma target. Our data show a strong enhancement of the stopping power of the plasma compared to that of a cold gas with equal density. The results completely confirm the predictions of the standard stopping power model.

    Notes: Abstract The energy loss of heavy ions in a hydrogen plasma has been measured in an energy range from 1.4 to 6 MeV/u. A z-pinch has been used as a plasma target with a maximum free electron density of 1.5×10 19 cm −3 . Our data show a strong enhancement of the stopping power of the plasma compared to that of a cold gas with equal density. Charge state analysis of the ions also show a higher charge state of the ions in the plasma target, relative to the cold hydrogen gas targets. A plasma lens effect of the high power z-pinch discharge was observed in our experiments.
