    Notes: The usefulness of gel filtration through cross-linked dextrans as a means of separating protein components in the water extracts of flour was investigated. Dextrans employed included Sephadex G-25, G-50, G-75, G-100, and G-200, while distilled water and several concentrations of lactic acid were used as eluting solvents. The most effective combination was Sephadex G-100 gel with 0.5N lactic acid as eluant. Although single protein components could not be isolated by this technique, it was possible to effect a simplification of the protein mixture and a concentration of some components in relatively small fractions of the eluate from gel columns. The combination of gel filtration and preparative starch-gel electrophoresis was utilized to isolate a fraction which migrated electrophoretically as a single component.

    Notes: Isoelectric focusing (IEF) and immunoblotting were used to detect genetic variants of malt endopeptidase (MEP1), an enzyme related to malting quality in barley and coded by the CepB locus on barley chromosome 3 (= 3H). A variant was found in a Turkish accession of wild barley (Hordeum vulgare ssp. spontaneum). The self progeny of a hybrid between this accession and the barley cultivar ‘Clipper’ were analyzed for recombination between the CepB locus and other isozyme loci. The estimates of recombination linked the CepB locus to an NADH diaphorase locus (Ndh2), which in turn was linked to the seedling esterase complex (Est1, Est2, and Est4) situated near the distal end of the long arm of chromosome 3. The Ndh2 locus was independent of two other NADH dehydrogenase loci (Ndh3, Ndh5) which were mapped on barley chromosome 5 (= 1H) in relation to the three hordein loci (Hor1, Hor2, and Hor3).

    Notes: Abstract Nine women with primary ovarian failure, who were having their artificial menstrual cycles manipulated with physiological levels of estrogen and high doses of progesterone, were entered into the study. They filled in urinary symptom questionnaires and had urodynamic investigations in the two phases of treatment: estrogen and progesterone, and estrogen alone. The number of voids per 24 hours was significantly greater in the progesterone phase, as was the end filling pressure on cystometry. This is the first report in the literature of the effects of high-dose progesterone on the lower urinary tract.

    Description / Table of Contents: Übersicht Die N-Parameter-Methode der Integralbeziehungen von Galerkin, Kantorovich und Dorodnitsyn gehört zur gleichen Klasse wie die Verfahren von Ritz und Galerkin. Diese Methode wird benützt, um Lösungen für die stationäre, inkompressible, zwei-dimensionale Strömung einer laminaren Grenzschicht zu finden. Allgemeine Lösungen N. Ordnung werden für Gebiete mit beschleunigter Strömung erhalten und, mit gewissen Abänderungen zur Berücksichtigung eines möglichen Ablösepunktes, auch für Gebiete einer verzögerten Strömung. Die Konvergenz und die Genauigkeit der Methode werden durch Vergleich der Lösungen mit zahlreichen ähnlichen und nicht-ähnlichen Strömungsproblemen untersucht. Die Methode erlaubt eine beliebig weitgehende Annäherung an den Ablösepunkt, ohne daß numerische Schwierigkeiten auftreten oder besondere Grenzwertbetrachtungen erforderlich wären.
    Notes: Summary The Galerkin-Kantorovich-Dorodnitsyn N-parameter method of integral relations belongs in the same general category as those of Ritz and Galerkin. The method is employed to solve the steady, incompressible, two-dimensional flow of a laminar boundary layer. General Nth-order solutions are obtained for regions of accelerated flow and, with a modification to account for a possible separation point, for regions of retarded flow. The convergence and accuracy of the method are evaluated by comparing the solutions with a large number of similar and nonsimilar flow problems. The method permits a separation point to be approached as closely as desired without encountering numerical difficulties or requiring special continuation techniques.

    Notes: Summary Accessions of Hordeum vulgare ssp. spontaneum, the wild progenitor of barley, collected in Israel (70), Iran (15) and Turkey (6) were screened for seedling response to four isolates of Rhynchosporium secalis, the pathogen causing leaf scald in barley. Resistance was very common in the collection (77%) particularly among accessions from the more mesic sites (90%). The genetics of this resistance were investigated in fifteen backcross (BC3) lines that contained an isozyme variant from H.v. ssp. spontaneum in a H.v. ssp. vulgare (cv. Clipper) background and were resistant to scald. Segregation in the BC3F2 families conformed with a single dominant resistance gene in 9 of the 15 lines. Scald resistance and the isozyme marker were closely linked in three of the BC3-lines, loosely linked in four and unlinked in the remaining eight. Scald resistance genes were identified on barley chromosomes 1, 3, 4 and 6. Crosses between several of the scald resistant BC-lines together with the linkage data indicated that at least five genetically independent resistances are available for combining together for deployment in barley. The linkage of scald resistance in several BC3-lines to the isozyme locus Acp2 is of special interest as this locus is highly polymorphic in wild barley.
