    Methods of computation of suspended load from bed materials and flow parameters (1981)
    Oxford, UK : Blackwell Publishing Ltd
    Sedimentology 28 (1981), S. 0 
    Details
    ISSN: 1365-3091
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Geologie und Paläontologie
    Notizen: Computation of the grain-size distribution of the suspended load above a sand bed must take into consideration: (1) sorting processes from the bed to the bed layer and (2) sorting between the bed layer and suspension. Grain-size distributions of the bed layers above sand beds of three different types have been computed in this work, both by the Einstein and the Gessler methods. Using these as references, suspended load distributions have been obtained in each case by the Rouse suspension equation. A new formula has also been developed in partial modification of Hunt's method for direct computation of bed load and suspended load from a bed's grain-size distribution and flow parameters.Comparison of the computed data with actual observations in laboratory flumes show that no one method is particularly superior to the others, but the present method is advantageous because it affords direct computation of the suspended load from a bed's grain-size distribution, without going through an intermediate stage (bed load). The possible sources of error in each of the methods have been discussed.

    ON SIEVING AND SETTLING TECHNIQUES FOR SAND ANALYSIS (1968)
    Oxford, UK : Blackwell Publishing Ltd
    Sedimentology 11 (1968), S. 0 
    Details
    ISSN: 1365-3091
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Geologie und Paläontologie
    Notizen: The basic differences between mechanical analysis of sand by Ro-Tap sieving and by settling in a sedimentation balance are discussed. The Groningen balance can continuously and rapidly record settling times of the grains (50–1,000 μ) of a 1.5-g sample with a maximum recording and reading error of about 2%.The theory of sieving is not fully developed yet, nor has the theory of settling of sand-sized particles been adequately expressed by any mathematical law. The drag coefficient (CD) and Reynolds number (Re) relation often used to derive diameter (d) from settling velocity (v) in this size range, are calculated from experimental data on diameter and velocity. Conversion of settling times to “sedimentation diameters” with the help of experimental curves for single, spherical quartz grains and their comparison with the corresponding “sieve diameters” are often found to be unsatisfactory in the case of natural sands, because shape and density variations of every individual grain in a sample can never be taken into account. Therefore, the use of settling velocity as a new grain parameter is advocated.

    Bounding solutions of systems of equations using interval analysis (1981)
    Springer
    BIT 21 (1981), S. 203-211 
    Details
    ISSN: 1572-9125
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Mathematik
    Notizen: Abstract We introduce some variations of the interval Newton method for bounding solutions to a set ofn nonlinear equations. It is pointed out that previous implementations of Krawczyk's method are very inefficient and an improved version is given. A superior type of Newton method is introduced.

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung An drei Kreuzungsreihen von Sorten unterschiedlicher Hülsenfarbe (schokoladenbraun, rostrot, grün mit schokoladenbraunen Streifen und grün mit rostroten Streifen) wurde die Vererbung dieses Merkmals bei der Straucherbse (Cajanus cajan (L.) Millsp.) untersucht. Für das Auftreten der schokoladenbraunen Hülsenfarbe ist das GenL verantwortlich,L r, ein bisher unbekanntes Allelomorph vonL, für die rostrote Farbe, während das GenD die Verteilung der Farbe steuert.L ist vollständig dominant überL r undD unvollständig dominant überd. Auf Grund der gemachten Feststellungen werden die Genotypen für die einzelnen Phänotypen angegeben.
    Notizen: Summary From three sets of crosses involving the phenotypes chocolate, red oxide, green with chocolate streaks and green with red oxide streaks, the action of the genes governing the phenotypes of the pods ofCajanus cajan (L.) Millsp. has been proposed. GeneL controls production of chocolate colour,L r an allelomorph ofL hitherto unreported, controls production of red oxide colour and geneD controls distribution of this colour. As regards inheritance of these two genes, the relationships betweenL andL r isL〉L r andD is incompletely dominant overd. The genotypes of the different phenotypes have been presented.

    Post-translational processing of 7S and 11S components of soybean storage proteins (1981)
    Springer
    Plant molecular biology 1 (1981), S. 19-34 
    Details
    ISSN: 1573-5028
    Schlagwort(e): Glycine max ; storage protein biosynthesis ; in vitro translation
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie
    Notizen: Abstract The synthesis and processing of the major storage proteins in soybean cotyledons was studied both in vivo and in vitro. The α and α′ subunits of 7S as well as the 11S proteins are synthesized as higher molecular weight-precursors on membrane-bound polysomes. The initial translation products of the 7S are proteolytically cleaved during translation suggesting the removal of a ‘signal peptide’ as evidenced by the presence of 2α and 2α′ peptides immunoreactive with 7S antibody in the in vitro chain completion products of the membrane-bound polysomes. This is followed or accompanied by cotranslational glycosylation, which increases their size equivalent to that of initially-synthesized precursors. In vivo pulse-labelled 7S α and α′ products are of slightly higher molecular weights than the immunoprecipitable chain-completion products, indicating further post-translational modifications. A slow post-translational processing during a period of 1.5 to 16 h yields the final 7S α and α′ glycoproteins. Acidic and basic subunits of the 11S protein appear to be synthesized from common large molecular weight (60K-59K) precursors. Antibodies to the 11S acidic component recognize both acidic and basic domains in the precursor while those raised against basic subunits appear to be specific for that region only. The processing of the 11S precursor is also very slow and occurs post-translationally. This slow rate of processing, coupled with a temporal difference in the synthesis of 7S and 11S components, suggests a highly coordinated mechanism for synthesis and packaging of these proteins into protein bodies during seed development.

    Jack-knifing the ratio and the product estimators in double sampling (1981)
    Springer
    Metrika 28 (1981), S. 245-256 
    Details
    ISSN: 1435-926X
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Mathematik
    Notizen: Summary Almost unbiased ratio and product type estimators have been obtained with the help of the Jack-Knifing technique for simple random sampling in two phases. The mean square errors of the resulting estimators have been compared with those of the corresponding usual (biased) estimators and it has been found that they are approximately same. This study generalizes similar single sampling results ofDurbin [1959],Shukla [1976] and others.
