    Notes: Abstract The nucleus5Li has been investigated within an excitation range of 17.8 – 21.1 MeV by measuring γ-rays from the reaction D(τ, γ o)5Li. In this range, excitation functions and angular distributions have been taken. The excitation functions exhibit broad maxima at 20 MeV which indicate, in agreement with other results, a level or a group of levels. Assuming that there is only one resonance, its properties are discussed. On the basis of the existing and the new experimental results, aJ π=1/2+ assignment is proposed besides the former resultJ π=(3/2, 5/2)+.

    Notes: Zusammenfassung Eine morphometrische Analyse menschlicher, entzündeter Gingiva ergab im Vergleich zu normalem Bindegewebe 70% weniger Kollagenfasern, dreifach vergrösserte und pathologisch veränderte Fibroblasten und eine kleine Population charakteristischer Immunoblasten mit einer Zellansammlung, die zu 76% aus Zellen der Lymphozytenserie bestand. Die Grösse der Fibroblasten war positiv mit der steigenden Zahl der Lymphozyten korreliert. Diese Befunde weisen auf eine Immunreaktion mit zytotoxischen Auswirkungen auf Fibroblasten des gingivalen Bindegewebes hin.

    Notes: Abstract The linewidth of a cw-single-mode tunable dye laser has been investigated. It was found that the linewidth is determined by microscopic velocity fluctuations of the turbulent flow within the dye cell of the laser and by fluctuations of the pump power. The linewidth is further influenced by mechanical disturbances and by temperature fluctuations of the dye solution. The results of the investigations made it possible to achieve a reduction of the velocity fluctuations. It is shown that under adequate operating conditions the free-running dye laser has a linewidth of 2 MHz.

    Description / Table of Contents: Experience gained with protective coating systems on steel underwater structures managed by Wasser- und Schifffahrtsverwaltung in the North Sea and Baltic Sea regionsIn order to develop protection systems for steel underwater structures in the coastal regions long-term exposure tests have been carried out at Kiel-Holtenau, Büsum and Brunsbüttelkoog (Germany); the tests included exposure to seawater and brackish water. On the basis of the results obtained it was possible to design coating systems having relatively long useful life. The behaviour ob these systems under practical application conditions is in agreement with the results obtained during the tests. On this basis it is possible to define requirements concerning in efficient coating: derusting to the blank metal;Zn dust primer; coating of tar modified epoxy resins having a minimum coating thickness of 500 μm; (multicoat systems on tar-epoxy basis are not satisfactory); thick coatings on polyurethane basis are promising for the future.
    Notes: Um Schutzmaßnahmen für Stahlwasserbauten im Küstenbereich zu entwickeln, wurden Langzeitversuche in Kiel-Holtenau und Büsum sowie Brunsbüttelkoog durchgeführt, wobei sowohl die Einwirkung von Meerwasser als auch die von Brackwasser untersucht wurde. Aufgrund der dabei erhaltenen Ergebnisse konnten neue Beschichtungssysteme mit verhältnismäßig langer Lebensdauer entwickelt werden. Das Verhalten der Systeme unter Praxisbedingungen entspricht den bei den Versuchen erhaltenen Ergebnissen. Auf dieser Grundlage lassen sich die an eine Beschichtung zu stellenden Anforderungen wie folgt definieren: Metallblanke Entrostung; evtl. Zn-Staubbeschichtung als Grundierung; Überzug auf Teerepoxidbasis mit mindestens 500 μm Schichtdicke (Mehrschichtenanstriche auf Teerepoxidbasis haben sich nicht bewährt); Dickschichtüberzüge auf Polyurethanbasis dürften sich in Zukunft durchsetzen.
