    Seltene Metallverbindungen in Sedimenten (1955)

    Notes: Zusammenfassung An 2 Beispielen (Zinnober und Baryt) wird erörtert, wie es in Sedimenten zur mehr oder weniger frühzeitigen Ausscheidung von relativ seltenen Metallverbindungen kommt unter bemerkenswerter Konzentrationswanderung. In vielen, aber nicht in allen Fällen erscheint als Vorbedingung der Mineralbildung die Gegenwart von Hohlräumen im Sediment. Die Gegenwart organischer Materie scheint wenigstens in einem Teil der Fälle die Konzentrationswanderung zu begünstigen.

    Photolithotrophy, photoheterotrophy, and chemoheterotrophy: Patterns of resource utilization on an annual and a diurnal basis within a pelagic microbial community (1979)

    Notes: Abstract An annual investigation of rates of photolithotrophy, photoheterotrophy, and chemoheterotrophy utilizing glucose and bicarbonate was made within the pelagic zone of a small, hardwater, southwestern Michigan lake. Sampling proceeded on a monthly, diurnal, and depth-wise basis. Annual mean photoheterotrophic uptake was estimated at 2.6μg C m−3h−1. Two periods of relatively high activity were observed: one during spring overturn and the second during the late summer period. In general, greatest contributions to overall carbon cycling occurred during morning to midday incubation periods and at intermediate depths within the water column. Rates of chemoheterotrophy averaged 6.9μg C m−3h−1 and were relatively uniform throughout the annual period. Greatest overall chemoheterotrophic activity was associated with periods of overturn. In general, this activity increased throughout the day and with increasing depth within the water column. The annual mean for photolithotrophic fixation was 1.33 mg C m−3h−1. Greatest contributions to rates of photosynthesis were associated with epilimnetic waters during early morning and midday incubations. Relatively minor contributions to inorganic fixation were made by waters below the 6-meter contour. Spring overturn and late summer represented periods of particularly great photolithotrophic activity. Quantitative comparisons among carbon pathways indicate that rates of pelagic heterotrophy, both photo- and chemoheterotrophy combined, contribute small quantities of carbon to overall carbon metabolism in this oligotrophic system. Qualitative comparisons among pathways indicate strong spatial and temporal separation. The late summer period showed greatest seasonal separation of the three pathways. Spring values represented a period of relatively high activity for all three pathways. On a depth-wise basis, photolithotrophic activity was greatest near the surface and chemolithotrophic activity greatest near the bottom. Photoheterotrophy took an intermediate position between the two. Diurnally, photoheterotrophy and photolithotrophy showed greatest activity during midday and early morning periods, whereas chemoheterotrophy increased throughout the daylight period and reached maximal values in sunset incubations.

    Tests of quantum chromodynamics in the decay of the τ-lepton and in electron positron annihilation into hadrons (1979)
    Springer
    The European physical journal 3 (1979), S. 55-64 
    Details
    ISSN: 1434-6052
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract We present a method to derive upper and lower bounds for a large class of quantities measurable ine + e − annihilation into hadrons and in τ-decay. The theoretical input are the asymptotic expansions for the vacuum polarization functions of vector and axial vector currents in the euclidean region as given by QCD. Since our method allows straightforward inclusion of (as yet uncalculated) higher order terms in α s , there is the potential of making high precision tests of QCD even with experiments at rather moderate energies. We argue, therefore, that it may be very worthwhile to pursue experiments ate + e − storage rings below theJ/Ψ resonance and to measure the branching ratios for the decays of the τ-lepton with high accuracy. In the latter case we can also get information on the behaviour of the weak axial vector current which should be very interesting in connection with chiral symmetry breaking.

    Aminoacyl-tRNA synthetase families and their significance to the origin of the genetic code (1978)
    Springer
    Origins of life and evolution of the biospheres 9 (1978), S. 39-50 
    Details
    ISSN: 1573-0875
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Geosciences
    Notes: Abstract A correlation of various aspects of the protein structures and substrate and mechanistic specificities of the aminoacyl-tRNA synthetases has led to the identification of at least one family of enzymes probably derived from a common ancestral synthetase. While strong correlations exist only in one part of the array of 64 codons comprising the Genetic Code, this itself may be interpreted as a meaningful pattern, most consistent with a development of the present code from earlier codes containing fewer amino acids and fewer available codons. Specifically, strong correlations in the enzymes whose cognate tRNAs respond to codons containing a central pyrimidine, including the enzyme family of Ile-, Phe-, Val-, Met-, and Leu-tRNA synthetases, suggests that these enzymes evolved last, and that, therefore, an earlier version of the Genetic Code was comprised solely of codons containing a central purine. It is suggested that further study of the historical interrelationships of these enzymes could lead to a fairly detailed picture of how the Genetic Code developed.

    Dissections of a triangular prism (1975)

    Geometriae dedicata 4 (1975), S. 279-289 
    Details
    ISSN: 1572-9168
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics
    Notes: Abstract Three parallel, non-planar lines ξ, η, and ζ are given in ordinary 3-space, and distinct points X 1, X 2, ..., X x are given on ξ, Y 1, Y 2, ..., Y y on η, and Z 1, Z 2, ..., Z z on ζ. Into at most how many cells do the xyz triangular plane segments X i Y j Z k divide the interior of the triangular prism determined by the lines ξ, η, and ζ? We employ an ingenious method due to Alfred Brousseau to solve this problem of classical combinatorial geometry.
