    THE IMPACT-FLOOD CONNECTION: DOES IT EXIST? (1994)
    Oxford, UK : Blackwell Publishing Ltd
    Terra nova 6 (1994), S. 0 
    Details
    ISSN: 1365-3121
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geosciences
    Notes: In a recent article in Terra Nova, Kristan-Tollmann and Tollmann (1994) suggested that the Biblical Flood can be explained by seven fragments of a comet that impacted the ocean at seven locations on Earth at 03.00h (C.E.T.) on 23 September, 9545 yr BP. We demonstrate that all the ‘geological proofs’ that allegedly support their conclusions are not supported by the available data on impact cratering. Their hypothesis is based on insufficient and ambiguous data, selective citation, and incomplete comprehension of previous research.

    Notes: [Auszug] Realizing the possibility that many kinds of organisms might be involved, we were prepared to use agar plates of different compositions ; but we were surprised to find that the microflora of the leaves is much more uniform than might be anticipated. We proceeded as follows : from different trees we ...

    Notes: [Auszug] THE idea that the Earth suffered an impact from a large extraterrestrial body at the Cretaceous/Tertiary (K/T) boundary 65 million years ago is now almost unanimously accepted, to judge from a recent conference in Houston*. Less consensus exists about the damage that might have been inflicted on ...

    Notes: [Auszug] The question of whether the dinosaurs and other life forms were wiped out at the end of the Cretaceous period (66 million years ago) by a cosmic impact or by a more earthbound catastrophe may finally be answered with the discovery of glass tektites from the era in Haiti. The ...

    A simple model for estimating protein solubility in aqueous polymer solutions (1994)
    Chichester : Wiley-Blackwell
    Journal of Chemical Technology AND Biotechnology 60 (1994), S. 413-418 
    Details
    ISSN: 0268-2575
    Keywords: protein ; polymer ; aqueous solution ; solubility ; Chemistry ; Biochemistry and Biotechnology
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Process Engineering, Biotechnology, Nutrition Technology
    Notes: A simple scaling analysis of protein solubility in semi-diluted polymer aqueous solutions was derived based on the recent theoretical development of Abbott et al.1 on the interactions between protein spheres and entangled polymer coils and the experimental observations of Atha and Ingham2 on the polymer-induced protein precipitation. Both the hard-sphere nature of the protein and the flexibility of the polymer coils have been taken into account in the model. The experimental data can be fitted by using this model with physically reasonable values of the exponent. This approach may be useful in estimating protein solubilities in water in the presence of polymer from limited and usually costly experimental data.
