    Notes: Abstract The degree of sediment disturbance in the South Pass area is correlated to the average hydraulic conductivity, shear strength, and thermal gradient. Hydraulic conductivity averages 18, 6, and 4 × 10−7 cm/s in the undisturbed, moderately disturbed, and most disturbed sediments, respectively. Shear strength also decreases with increasing disturbance, from 7.6 to 4.4 to 3.5 kPa. Excluding the four stations dominated by annual temperature variations, the remaining 19 thermal gradients correlate well with sediment disturbance. The average gradient is positive in all of the disturbed sediments (0.12 ± 0.07° C/m) and 0 in the undisturbed sediments (0.02 ± 0.05° C/m).

    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.

    Notes: Abstract Pairwise combinations of genes for resistance to scald in barley were developed using linked isozyme markers to test whether such combinations conferred improved resistance to the pathogen, Rhynchosporium secalis. The resistance genes originally derived from Hordeum vulgare ssp. spontaneum. The combinations were bred into an essentially similar genetic background because the scald-susceptible, Australian barley cultivar ‘Clipper’ was the recurrent backcross parent in their ancestry. In field tests of the recombinants over 2 years, disease levels were lower in three of six doubly resistant lines than in backcross lines carrying a single resistance gene, which in turn were less diseased than either ‘Clipper’ or recombinants that lacked the marked resistance genes. All resistant lines significantly outyielded ‘Clipper’ but did not themselves differ significantly. Lines resistant to scald had significantly higher grain size and grain weight. Gains for malt yield of about 1 % were detected in the higher disease environment. Resistance was not accompanied by any obvious “cost” in terms of yield or quality. Protection against scald is therefore a significant requirement for new malting barley cultivars in scald-prone areas.

    Notes: Abstract  A genomic DNA fragment from Triticum tauschii, the donor of the wheat D genome, contains a starch branching enzyme-I (SBE-I) gene spread over 6.5 kb. This gene (designated wSBE I-D4) encodes an amino acid sequence identical to that determined for the N-terminus of SBE-I from the hexaploid wheat (T. aestivum) endosperm. Cognate cDNA sequences for wSBE I-D4 were isolated from hexaploid wheat by hybridisation screening from an endosperm library and also by PCR. A contiguous sequence (D4 cDNA) was assembled from the sequence of five overlapping partial cDNAs which spanned wSBE I-D4. D4 cDNA encodes a mature polypeptide of 87 kDa that shows 90% identity to SBE-I amino acid sequences from rice and maize and contains all the residues considered essential for activity. D4 mRNA has been detected only in the endosperm and is at a maximum concentration mid-way through grain development. The wSBE I-D4 gene consists of 14 exons, similar to the structure for the equivalent gene in rice; the rice gene has a strikingly longer intron 2. The 3′ end of wSBE I-D4 was used to show that the gene is located on group 7 chromosomes. The sequence upstream of wSBE I-D4 was analysed with respect to conserved motifs.

    Notes: Abstract: A rigorous extraction of the deuteron charge form factors from tensor polarization data in elastic electron-deuteron scattering, at given values of the 4-momentum transfer, is presented. Then the world data for elastic electron-deuteron scattering is used to parameterize, in three different ways, the three electromagnetic form factors of the deuteron in the 4-momentum transfer range 0-7 fm−1. This procedure is made possible with the advent of recent polarization measurements. The parameterizations allow a phenomenological characterization of the deuteron electromagnetic structure. They can be used to remove ambiguities in the form factors extraction from future polarization data.

    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.
