    Notes: Abstract –  We examine patterns in fish species assemblages in the Toxaway and Horsepasture rivers, two high elevation streams in North Carolina, USA. This region is noted for extreme topographical relief, high cumulative annual rainfall and many rare and endemic plants and animals. The study area encompasses a portion of the Blue Ridge Escarpment and the associated Brevard Fault Zone. We hypothesise that major waterfalls and cascade complexes have acted to limit invasion and colonisation by fishes from downstream. This hypothesis is supported by longitudinal fish assemblage patterns in our study streams. Fish species richness in Toxaway River increased from 4 to 23 between Lake Toxaway and Lake Jocassee, a distance of 10 river km. We found similar discontinuities in neighbouring Horsepasture River and Bearwallow Creek. We found no instances of species replacement along this elevation gradient, and the trend in increased diversity downstream showed discontinuities coincident with sharp elevation breaks. With regard to theories posited to explain community formation in headwater stream fish communities (especially in those characterised by high topographical relief), we suggest coloniser ‘access’ may be more important than other factors including competitive interactions.

    A relationship between erythrocyte volume and concentration in humans and other mammals (1980)
    Springer
    Annals of hematology 41 (1980), S. 421-426

    ISSN: 1432-0584

    Description / Table of Contents: Summary In 33 male and female human blood samples, red cell count decreased in a highly significant (p 〈0.01) non-linear fashion as MCV increased. An identical, equally significant relationship was obtained using published hématologie values for 20 other mammalian species. These findings suggest a hyperbolic relationship between RCC and MCV, with the latter as the independent variable.
    Notes: Zusammenfassung In 33 Blutproben von gesunden weiblichen und männlichen Versuchspersonen zeigt die Erythrozytenzahl bei Vergrößerung des mittleren Zellvolumens einen statistisch signifikanten nichtlinearen Abfall. Aus hämatologischen Daten der Literatur wurde eine bei 20 anderen Säugern gleiche und ebenfalls statistisch signifikante Beziehung gefunden. Es handelt sich dabei um eine hyperbolische Beziehung zwischen dem mittleren Zellvolumen und der Erythrozytenzahl, worin das Zellvolumen die unabhängige Veränderliche sein dürfte.

    Method for structural characterization of high polymeric networks by an osmotic pressure technique (1965)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: An apparatus was designed to measure the osmotic pressure of solvent-polymer systems. The method is unique in that semirigid polymers may be incorporated as the solute component without specimen fissures occurring from excessive solvent dilative action. The advantages of this technique are: high polymeric materials both elastomeric and plastic can be structurally characterized by the same technique; the calculated effective molecular weight of the polymer network will reflect a value consistent with the polymer's performance characteristics; and the method is only restricted to lyophilic polymer-solvent systems.
