    Dynamic mechanical measurements with the eccentric rotating disks flow (1974)
    Springer
    Rheologica acta 13 (1974), S. 814-829 
    Details
    ISSN: 1435-1528
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Physics
    Notes: Summary The forces generated by flow between eccentric rotating disks (ERD) are examined experimentally. ERD experiments are presented for severalNewtonian and viscoelastic fluids with viscosities ranging from 30 to 240 000 poise. The effects of disk separation, radius, misalignment, and eccentricity are studied. ERD data is compared to the dynamic shear moduli,G′ andG″, defined by small amplitude deformation in oscillatory shear flow. Results confirm theory that the two measurable shear forces generated in the ERD do measureG′ andG″. No significant boundary or inertial effects were noted, but in some cases instrument compliance can be significant. Normal stress measurements in the ERD are also reported.

    Closed systems and the rearing of fish larvae (1970)
    Springer
    Helgoland marine research 20 (1970), S. 691-696 
    Details
    ISSN: 1438-3888
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Description / Table of Contents: Summary 1. Various designs and techniques of closed system rearing of fish larvae are being developed using specific species chosen on the basis of their reproductive habits, ecological preference, and potential as environmental indicators. 2. The influence of the parameters of temperature, salinity, food, light, circulation, and the presence of autotropic organisms are tested using as criteria for the success of hatch and development. 3. To date, the results have produced several techniques which increase the percentage of success in raising fry and juvenile fishes.
    Notes: Kurzfassung Verschiedene Anordnungen und Verfahren zur Aufzucht von Fischlarven in geschlossenen Wassersystemen werden gegenwärtig entwickelt und geprüft. Die Auswahl der hierfür benutzten Fischarten erfolgt im Hinblick auf fortpflanzungsbiologische und ökologische Besonderheiten. Der Einfluß von Temperatur, Salzgehalt, Nährstoffen, Licht, autotrophen Organismen sowie der Wasserzirkulation werden anhand der Aufzuchterfolge erörtert. Einige Methoden für die Aufzucht von Fischbrut und Jungfischen werden kurz erläutert.

    Coral reef fishes which forage in the water column (1973)
    Springer
    Helgoland marine research 24 (1973), S. 292-306 
    Details
    ISSN: 1438-3888
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Description / Table of Contents: Summary 1. Radiation of fishes representing many families in the tropical coral reef has repeatedly produced convergence in the specialization for “water-column foragers”. 2. This life mode is depicted by a recognizable set of morphological and behavioral characteristics. Exploitation of this niche has parallel examples in fresh water, and non-tropical habitats. 3. The distinguishing traits of this specialization, and the systematic, ecological and evolutionary features are described and discussed.
    Notes: Extrait Dans un biotope à récif de corail, des espèces étroitement liées peuvent servir d'exemple de différenciation sur le plan de l'évolution. La radiation évolutive de poissons représentant plusieurs familles du récif corallien tropical a conduit à plusieurs reprises à la formation de «fourragers dans la colonne d'eau». Ce mode de vie comporte une série de caractères morphologiques et éthologiques définis. On trouve des éxemples similaires dans l'eau douce et dans des habitats non tropicaux. Les traits distinctifs de cette spécialisation, la systématique, les caractéristiques écologiques et celles se rapportant à l'évolution sont décrits et discutés.

    Hydrodynamic measurements for imperfect mixing processes: Newtonian Fluids (1971)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 17 (1971), S. 1387-1393 
    Details
    ISSN: 0001-1541
    Keywords: Chemistry ; Chemical Engineering

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: The response of a continuous flow mixing system to a step change in an input variable is discussed from the standpoint of dimensional analysis. This idea is presented as an alternative to using zone models for predicting residence time distributions in systems where imperfect mixing occurs.Mixing experiments were performed in a cylindrical flat bottomed tank geometrically similar to tanks commonly used for industrial processes. The response of the system to a step change in feed concentration was observed. Initially the tank contained a salt solution. At the start of an experiment, a stream of salt-free diluent was introduced at the top of the tank and a stream of the salt solution was drained from the bottom, keeping the liquid volume in the tank constant. The salt concentration in the output stream was measured continuously after the start of the experiment.The experimental results are correlated in terms of dimensionless variables, and the variables affecting the mixing process most strongly are determined. The results show that variations in throughput rate or in impeller shape or rotational speed affect the mixing process much more than does impeller position. The data are also compared with models proposed by other authors, and the model constants are evaluated.
