    Description / Table of Contents: Zusammenfassung 1. Es wird über Untersuchungen an 141 Jungen und 151 Mädchen berichtet, bei denen die körerliche Leistungsfähigkeit (W170) in der von Mocellin u. Rutenfranz vorgeschlagenen Weise bestimmt wurde. 2. Die Normierung der Untersuchungsergebnisse erfolgte über die Bezugsgrößen Alter, Körperlänge und Körpergewicht. Dabei fanden sich zwischen der W170 und Körpermaßen, außer zwischen W170 und Gewicht bei Jungen, keine linearen Beziehungen über größere Bereiche hinweg. 3. Es bestand eine Proportionalität zwischen Mittelwerten der W170 in verschiedenen Altersgruppen und den entsprechenden Streuungen. Als Streuungsmaß wurde deshalb der Variabilitätskoeffizient verwendet. 4. Die Entwicklung der W170 in Abhängigkeit von Lebensalter und Geschlecht wurde an Hand der Beziehungen zwischen W170 und Körpermaßen mit Hilfe der Normwerte von Meredith rechnerisch ermittelt. Die errechneten Werte werden mit den empirischen Werten verglichen. Die Möglichkeit alters- und geschlechtsspezifischer Besonderheiten wird diskutiert. 5. Unter Berücksichtigung einer methodenabhängigen Differenz der W170-Werte von 90 mkp min−1 werden die bei kontinuierlich steigender Leistung bestimmten W170-Werte auf Verhältnisse bei stufenweise steigender Leistung umgerechnet, so daß ein Vergleich mit den Werten anderer Untersucher durchgeführt werden kann.
    Notes: Abstract 1. A report is given of investigations on the physical performance capacity (W170) which was determined in the way proposed by Mocellin and Rutenfranz. 2. The results were classified according to age, height and body weight. Except for the relation between W170 and body weight in boys, no other linear relationship was recorded in boys and girls between W170 and physical parameters for a wider range. 3. The recorded mean values and the standard deviations of W170 at various developmental stages in boys as well as in girls tended to be proportionally related. Therefore the coefficient of variation was selected as standard for deviations of regressions. 4. The development of W170 in relation to sex and age was assessed according to relationships between W170 and physical parameters by means of normal values given by Meredith. The estimated values of W170 are compared with the empirical values of the investigated population. 5. Taking into account a systematic difference of 90 mkp min−1 between values of W170 obtained at continuous or at stepwise increase of load, our values have been transformed to conditions of a stepwise increase of load so that a comparison with values of other investigations is possible.

    Notes: Abstract On the basis of studies of about 100 collections of the groupConocybe mesospora and after comparison of extra-European material we conclude that, within the European representatives of this complex, it is necessary to distinguish nine species and two varieties. Three new species are described:Conocybe subxerophytica Sing. & Hauskn.,C. minima Sing. & Hauskn. andC. roberti Sing. & Hauskn. C. mesospora var.subalpina Sing. is now recognized as an autonomous species, butC. brunneola (Kühn. ex)Kühn. & Watling is understood as variety ofC. microspora (Velen.)Dennis. C. excedens var.pseudomesospora Sing. & Hauskn. is described as a new variety.C. affinis Sing. is indicated for Europe.C. microsperma Sing. is the new name ofC. microspora (Vel.)Dennis ss.Dennis. A full description of nine taxa of this group is given and a key to 11 taxa occurring in Europe added. Seven taxa are illustrated for the first time with colored photographs. All taxa known to us from other continents and belonging to theC. mesospora group have been compared with the most similar European species or varieties.

    Description / Table of Contents: High Temperature Fatigue of the Precipitation Hardened Alloy AlCuMnZr (2219) - A Study of the MicrostructureThe creep resistant alloy AlCuMnZr (age-hardened) was subjected to simultaneous fatigue and annealing (at 300°C). This condition (high temperature fatigue) is often found under operational conditions, e.g. in cylinder heads. The material was then studied by means of mechanical testing (hardness measurements) and optical and electron microscopy. It is shown by microscopy that the microstructure is inhomogeneous: Band-like regions are formed in which the phase transformation Θ′ → Θ has occurred. Coarsening of the precipitates is somewhat accelerated in the matrix due to fatigue. The results will be discussed on grounds of the literature and the existing theories.
    Notes: Die warmfeste Legierung AlCuMnZr (voll ausgehärtet) wird gleichzeitig einer Dauerschwingbelastung sowie einer Temperaturerhöhung (300 °C) unterworfen. Diese Beanspruchungskombination (Hochtemperatur-Ermüdung) tritt in der Praxis vielfach auf, u.a. in Zylinder-köpfen. Der Werkstoff wird anschließend mechanisch (Härtemessungen) sowie licht- und elektronenmikroskopisch untersucht. Die Mikroskopie erhellt die ausgeprägte Inhomogenität des Verformungsgefüges, das aus schmalen bänderförmigen Bereichen besteht, in denen die Phasentransformation Θ′ → Θ stattgefunden hat. Diese Bänder umschließen das Θ′-gehärtete Grundgefüge. In letzterem hat die Ermüdung das Teilchenwachstum im Vergleich zu einer Auslagerung ohne Belastung etwas beschleunigt. Die Ergebnisse werden im Lichte der vorhandenen Literatur und Theorien diskutiert.

    Notes: Using a multistage extraction apparatus of a new type, crude Thevetin was separated into the two components Cerberoside (Thevetin B) and Thevetin A. The solvent consumption was low and there was no disturbing emulgation of the phases in each other. The separation efficiency corresponds with the approximate calculations based on distribution coefficients and ratio of flow rates.

    Description / Table of Contents: On the Reaction of Phosphorus(III) Fluorides with Phenyl AzideThe reaction of phenyl azide with phosphorus(III) fluorine compounds was found to proceed according to the principle of a Staudinger reaction producing, normally, fluorine-containing N-phenylphosphine imides. From diethylamino difluorophosphine and phenyldifluorophosphine the dimers, [(Et2N)F2PNPh]2 and [PhF2PNPh]2, were obtained with phenyl azide. These compounds have previously been prepared by a different route. The compounds were characterized by elemental analysis, determination of the molecular weight, either cryoscopically or by mass spectrometry as well as through their n.m.r. spectra (1H, 19F and 31P).
    Notes: Die Umsetzung von Phenylazid mit Phosphor(III)-Flour-Verbindungen verlief im Sinne einer Staudinger-Reaktion, im Regelfalle unter Bildung von fluorhaltigen N-Phenylphosphinimiden. Aus Diethylaminodifluorphosphin sowie Phenyldifluorphosphin und Phenylazid wurden die auf anderem Wege bereits dargestellten Dimeren [(Et2N)F2PNPh]2 und [PhF2PNPh]2 erhalten. Die Verbindungen wurden durch Elementaranalyse, kryoskopische und massenspektrometrische Molekulargewichtsbestimmungen, sowie durch NMR-Spektren (1H, 19F und 31P) charakterisiert.
