    Notes: Abstract Fowl plague virus, strain Dutch, was metabolically labeled withd-[2-3H]mannose, or withd-[6-3H]glucosamine, and the small subunit (HA2; 0.8 mg in total) of the viral hemagglutinin was isolated by preparative sodium dodecylsulfate-polyacrylamide gel electrophoresis. After proteolytic digestion, the radioactive oligosaccharides were sequentially liberated from the glycopeptides by treatment with different endo-β-N-acetylglucosaminidases and with peptide:N-glycosidase or, finally, by hydrazinolysis. In this manner, four groups of glycans could be obtained by consecutive gel filtrations and were subfractionated by HPLC. The structures of the individual oligosaccharides were analyzed by micromethylation, by acetolysis or by digestion with exoglycosidases. The major species amongst the high mannose glycans at Ans-406 of the viral glycopolypeptide were found to be Manα1-2Manα1-3(Manα1-2Manα1-6)Manα1-6(Manα1-2Manα1-2Manα1-3)Manβ1-4GlcNacβ1-4GlcNAc and Manα1-3(Manα1-2Manα1-6)Manα1-6(Manα1-2Manα1-2Manα1-3)Manβ1-4GlcNAcβ1-4GlcNAc, while the complex glycans at Asn-478 are predominantly GlcNAcβ1-2Manα1-3(GlcNAcβ1-2Manα1-6)Manβ1-4GlcNAcβ1-4GlcNAc (lacking, in part, one of the outerN-acetylglucosamine residues) and GlcNAcβ1-2Manα1-3(Galβ1-4GlcNAcβ1-2Manα1-6)Manβ1-4GlcNAcβ1-4GlcNAc.

    Die mesozoische Magnafazies-Abfolge in den nördlichen Anden (Peru, Ekuador, Kolumbien) (1980)

    Description / Table of Contents: Abstract Over 100 sedimentary formations and groups are known from the epicontinental to continental Mesozoic (“Oriente Andino” sensu H.Bürgl) in the Andean region of Peru, Ecuador and Colombia. These lithostratigraphic (or facial) complexes are attached to 6 magnafacies-units which follow each other chronologically, thereby clearly evidencing a uniform paleogeographic-sedimentary development in the mentioned areas, although the geological structure of the Western respectively Coastal Cordilleras of the North (Colombia, Ecuador) is fundamentally different from that of the Southern ones (Peru, Chile).
    Abstract: Resumen Más de 100 grupos y formaciones sedimentarios des »Oriente Andino« (sensu H.Bürgl) en los Andes septentrionales (PerÚ, Ecuador, Colombia) están asociados a 6 unidades magnafaciales que se suceden cronológicamente. Este »Oriente Andino« abarca las cuencas sedimentarias de tipo epicontiental a continental de la época mesozoica. Se bosqueja así claramente, en las áreas mencionadas, una evolución paleogeográfica-sedimentológica bastante uniforme, aunque las estructuras geológicas de las Cordilleras Occidentales (o Costeras, respectivamente) de la parte septentrional (Colombia, Ecuador) se diferencian fundamentalmente de las del Sur (PerÚ, Chile).
    Notes: Zusammenfassung Die weit über 100 sedimentären Formationen und Gruppen im mesozoischen epikontinentalen bis kontinentalen „Oriente Andino“ der nördlichen Anden (Peru, Ekuador und Kolumbien) werden 6 zeitlich aufeinanderfolgenden Magnafazies-Einheiten zugeordnet. Dabei zeichnet sich deutlich eine einheitliche paläogeographisch-sedimentäre Entwicklung in den genannten Räumen ab, obwohl sich der geologische Bau der andinen West- bzw. Küstenkordilleren im Norden (Kolumbien, Ekuador) grundsätzlich vom Süden (Peru, Chile) unterscheidet.

    Nonlocal light-cone expansions and evolution equations (1985)
    Springer
    The European physical journal 26 (1985), S. 591-600 
    Details
    ISSN: 1434-6052

    Topics: Physics
    Notes: Abstract A new variant of the nonlocal light-cone expansion in QCD is proposed. The anomalous dimension of the corresponding fermion flavour nonsinglet operator is calculated in the one-loop approximation and shown to coincide (up to a trivial diagonal factor) with the Brodsky-Lepage kernel. The connection of our approach with the standard local conformal light-cone expansion is briefly discussed. An exclusive light-cone dominated process is considered within the framework of our formalism. The evolution equation obtained earlier by different methods is recovered in a particularly straightforward and compact manner.

    Hadron operators on the light-cone (1986)

    Topics: Physics
    Notes: Abstract Meson and baryon operators on the light cone are studied which reproduce the well-known parton distribution amplitudes as matrix elements between the vacuum and an one-meson (baryon) state. We extent our previous results to the case of the quark-gluon mixing which is relevan for the description of a flavour-singlet meson. The anomalous dimensions of the considered nonlocal light-cone operators are calculated explicity in the one-loop approximation. We thus recover the evolution kernels for meson and baryon wave functions derived earlier by other authors using different methods.

    On the structure of the ‘red’ globular cluster NGC 1806 in the large magellanic cloud (1982)
    Springer
    Astrophysics and space science 84 (1982), S. 133-141

    Topics: Physics
    Notes: Abstract A structural study of the old globular cluster NGC 1806 in the LMC has been carried out by star counts onB- andV-ESO 3.6 m telescope plates with three different limiting magnitude levels. The star density distribution was obtained directly from the surface strip count function with the Plummer formalism and the generalized Schuster law according to Lohmann. This yields beside the central density the structural parametern and the characteristic length parameterR 0 for each individual colour and magnitude level. The results show that the blue stellar content of NGC 1806 — the horizontal branch stars — is more concentrated towards the cluster center than the red giant and subgiant objects. Also such a dynamical mass segregation is observed for the red giants compared with the subgiants.

    Notes: Abstract HEAO-B (Einstein) satellite measurements with the Imaging Proportional Counter revealed the W UMa binary system TZ Bootis as an X-ray source. It is estimated that the luminosity ratioL x/Lvof this system is about 10−3.8 indicating that TZ Bootis is in the transition region between A- and W-type W UMa systems.

    Nonlocal light-cone operators describing hadrons in processes with large momentum transfer (1987)
    Springer
    Czechoslovak journal of physics 37 (1987), S. 516-520 
    Details
    ISSN: 1572-9486
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The application of a special version of the nonlocal light-cone expansion to hadron processes with large momentum transfer is reviewed. The light-cone operators introduced in this approach may be considered as the relevant hadron operators: Their matrix elements between the vacuum and a one-hadron state coincide with the quark distribution amplitude, and their anomalous dimensions are unique extensions of the well known Brodsky-Lepage evolution kernels having also a simple relation to the Altarelli-Parisi kernels.
