    Occurrence and nature of mixed infections in nodules of field-grown soybeans (Glycine max) (1987)
    Springer
    Biology and fertility of soils 5 (1987), S. 112-114 
    Details
    ISSN: 1432-0789
    Keywords: Mixed nodule infections ; Glycine max ; Soybeans ; Bradyrhizobium japonicum strains ; Field inoculation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Geosciences , Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Mixed infections of Bradyrhizobium japonicum strains in early and late nodules of four soybean cultivars were studied in a field soil. Nodule occupants were identified by immunofluorescence using serogroup specific antibodies prepared against B. japonicum strains USDA 110, USDA 123, and USDA 138. Double infection was determined directly by combined examination of the same microscopic field by fluorescence and phase contrast microscopy. Double strain occupancy was observed consistently, and its occurrence did not differ substantially in pouch, soil pot, and field experiments, ranging in incidence from 12% to 32%. No significant differences in the incidence or nature of double infection could be attributed to cultivar, seed inoculation, or plant maturity. Strains reactive to strain USDA 123-fluorescent antibody were dominant in both singly and doubly infected nodules irrespective of cultivar, plant age, or seed inoculation with strain USDA 110.

    Cotransposition of a highly repetitive DNA element with flanking sequences in the genome of the midgeChironomus thummi (1987)
    Springer
    Journal of molecular evolution 26 (1987), S. 311-319

    ISSN: 1432-1432
    Keywords: Chironomus thummi ; Repetitive DNA ; Cotransposition ; NTS of rDNA ; Claelements ; Satellite DNA ; DNA amplification
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary A family of highly repetitive DNA elements, the Cla-elements, is present in the genomes of the two sibling speciesChironomus th. thummi andCh. th. piger. These Cla-elements are organized in large tandem repetitive clusters as well as occuring as interspersed monomeric elements, in both subspecies. The analysis of a monomeric Cla-element and several kilobases of its flanking sequences fromCh. th. piger revealed that the short Cla-elements are cotransposed together with adjacent DNA. We found the same association of Cla-elements with specific flanking DNA in clones obtained from the rDNA ofCh. th. thummi and from nonribosomal Cla-DNA ofCh. th. piger. The Cla-element-flanking DNA is clearly also repetitive, but mainly of inter-spersed organization.

    Evolutionary conservation of the 3′ ends of members of a family of giant secretory protein genes inChironomus pallidivittatus (1987)
    Springer
    Journal of molecular evolution 25 (1987), S. 20-28 
    Details
    ISSN: 1432-1432
    Keywords: Balbiani rings ; Evolution ; Immunological detection ; Nucleotide sequence ; 3′ End
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Two cDNA clones representing the 3′-end regions of BR1 and BR2 75S mRNA were obtained fromChironomus pallidivittatus. The regular structure characterizing the core of these genes, consisting of tandemly arranged repeat units, changes into a more irregular structure toward the 3′ end. Distal to a standard type of repeat unit with a characteristic excess of positive charges, a new type of repeat with a high, negative charge density is interspersed among parts of the standard unit. The last 111 amino acids before the stop codon represent a unique region distinctly different in amino acid composition from upstream regions, and include two partially homologous hydrophobic regions. Sequence comparison of 3′-end regions from clones representing BR1 and BR2 genes indicates striking sequence conservation in the unique part of the region. Analysis of the level of silent site divergence shows that the homology increases in the 3′ direction up to the polyadenylation site. That the unique region is retained as a part of the secreted protein is shown by Western blotting.

    Notes: Abstract On the ozonization of larixol in methanol followed by treatment with ammonium chloride, the main reaction products were 15,16,20-trisnorlabd-6-ene-8,13-dione and 6-hydroxy-8,13;8,14-diepoxy-15,20-bisnorlabd-14-one. When ozonization was performed in methanol in the presence of dimethyl sulfide or in methylene chloride in the presence of pyridine, 6,14-dihydroxy-8,13;8,14-diepoxy-15,20-bisnorlabdane and 6-hydroxy-14,50,20-trisnorlabd-8,13-dione predominated in the reaction products.

    Inverse design of supercritical nozzles and cascades (1986)
    Chichester [u.a.] : Wiley-Blackwell
    International Journal for Numerical Methods in Engineering 22 (1986), S. 417-432 
    Details
    ISSN: 0029-5981
    Keywords: Engineering ; Engineering General
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Mathematics , Technology
    Notes: A computation method for the inverse design of supercritical cascades is described. It yields the flow field and the cascade geometry for a prescribed velocity distribution, which may be optimized by boundary-layer calculation. Some developments of the method for convenient application and high accuracy - automatic tuning of the upstream boundary distributions, local mesh refinement with emboxed regions for high resolution of steep gradients - are shown. Comparison between calculation and experiment of the complete flow field is made for a supercritical nozzle flow, and comparison with another method for a turbine cascade. A supercritical compressor cascade and blades for a three-stage axial compressor have been designed. They produced lower losses and higher efficiency in comparison with conventional NACA blades.

    Decay channels of core excitation resonances in 3d and 4f metal atoms (1986)
    Springer

    Topics: Physics
    Notes: Abstract Photoabsorption, photoelectron, and ejected electron spectra of atomic 3d metals and rare earths in the energy range of the strong 3p→3d and 4d→(4fεf) excitations are presented. TheZ-dependence of the strength, shape and decay channels of the giant resonances is discussed. With increasing Z for the 3d metals the 3p→3d resonances change from almost symmetric lines close to the 3p-ionization limits to broad asymmetric profiles centered well below the 3p-ionization threshold. Autoionization leading to the emission of a 3d electron dominates the decay. For lowZ rare earths the 4d→(4fεf) resonances mainly decay via the emission of a 4d electron whereas for higherZ the emission of a 4f electron takes over.
