    Notes: [Auszug] IN NATURE of February 21, Prof. Wood, referring to my letter of January 17, says that the effects observed were probably due to disturbance of the density gradient of the sodium vapour caused by “local heating by the wire.” I am afraid that in my letter I cannot have described the experimental ...

    Notes: [Auszug] DR. STARK (NATURE, vol. lxxiii., pp. 78, 389, 533) has given a theory, based on his canal-ray experiments, according to which spectrum series are due to positive ions. It occurred to me that its applicability to thermal emission might be tested by experiments on the ionisation accompanying the ...

    Notes: [Auszug] IN reply to Mr. Campbell's letter of April 30, it must suffice to point out that my letter of March 5 was limited to infinite spectrum series and to luminous gases. This seemed to me at the time of writing obvious from the context, as well as from the express reference to the finiteness of the ...

    Notes: [Auszug] THE electrical theory of dispersion is based on the hypotheses (1) that electric waves are due to motions of electric charges, and waves of light in particular to vibrations of charges inside the atom; and (2) that these vibrations are governed by linear equations. On this basis we obtain the ...

    Description / Table of Contents: Effects of Loading Sequences and Size of Repeated Stress Block of Loads on Fatigue Life Calculated using Fatigue FunctionsIt is well-known that collective form, stress intensity and loading sequence of individual stresses as well as size of repeated stress blocks can influence fatigue life, significantly. The basic variant of the consecutive Wöhler curve concept will permit these effects to be involved into fatigue life computation. The paper presented will demonstrate that fatigue life computations using fatigue functions reflect the loading sequence effect with multilevel loading precisely and provide reliable fatigue life data. Effects of size of repeated stress block and loading sequence on fatigue life as observed with block program tests can be reproduced using the new computation method.
    Notes: Man weiß, daß Kollektivform, Beanspruchungsintensität und Reihenfolge der einzelnen Beanspruchungen sowie der Umfang der periodischen Teilfolgen die Lebensdauer bei Blockprogrammversuchen signifikant beeinflussen können. Die Basisvariante des Folge-Wöhler-Kurven-Konzepts erlaubt die Einbeziehung dieser Einflüsse in die Lebensdauerberechnung. Im vorliegenden Beitrag wird gezeigt, daß die Lebensdauerberechnungen mit Ermüdungsfunktionen den Reihenfolge-Effekt bei Mehrstufenbelastungen richtig widerspiegeln und treffsichere Lebensdauerwerte liefern. Die bei Blockprogrammversuchen beobachteten Einflüsse von Teilfolgeumfang und Reihenfolge auf die Lebensdauer sind mit Hilfe des neuen Berechnungsverfahrens nachvollziehbar.

    Description / Table of Contents: Fatigue Life Calculation on the Basis of Fatigue FunctionsSpecific two-step tests constitute the basis of the fatigue functions determination. They consider the fatigue state reached during preloading in the action on the following stress step. The fatigue functions control the sequence of the fatigue life calculation at multi-step and random loadings.
    Notes: Ausgewählte Zweistufenversuche bilden die Grundlage für die Aufstellung von Ermüdungsfunktionen. Sie berücksichtigen den während der schwingenden Vorbelastung erreichten Ermüdungszustand in seiner Auswirkung auf die nachfolgende Belastungsstufe. Die Ermüdungsfunktionen steuern den Ablauf der Berechnung der Lebensdauer bei Mehrstufen- und Randombelastungen.

    Notes: CaSi2 wurde in geschmolzenem AlBr3 bei Temperaturen zwischen 100°C und 200°C mit HBr behandelt. Es wurden hierbei bei den niedrigeren Temperaturen (etwa 100 bis 150°C) lepidoide Polysilane sehr niedriger Oxydationsstufe erhalten. Sie bestehen aus hexagonalen Si-Doppelschichten. Die vierten Valenzen der Si-Atome sind teils durch H- und Br-Atome abgesättigt, teils scheinen sie radikalartigen Charakter zu tragen.Mit steigender Versuchstemperatur nimmt der H-Gehalt ab und in zunehmendem Maße verknüpfen sich die Si-Schichten unter Ausbildung kleiner Bezirke dreidimensionalen Siliciums.

    Notes: Durch Umsetzung von Tribromsilan mit Magnesium in ätherischer Lösung gelang es, das Polysilan (1) (SiH)n in größeren Mengen relativ leicht und in befriedigender Reinheit darzustellen. Eine geringe Substitution der H-Atome durch Brom war nicht zu vermeiden, sie hielt sich jedoch in niederen Grenzen.
