    Inverting travel times with a triplication (1982)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: A method based on the use of constrained spline fits is used to overcome the difficulties arising when body-wave data in the form of T-delta are reduced to the tau-p form in the presence of cusps. In comparison with unconstrained spline fits, the method proposed here tends to produce much smoother models which lie approximately in the middle of the bounds produced by the extremal method. The method is noniterative and, therefore, computationally efficient. The method is applied to the lunar seismic data, where at least one triplication is presumed to occur in the P-wave travel-time curve. It is shown, however, that because of an insufficient number of data points for events close to the antipode of the center of the lunar network, the present analysis is not accurate enough to resolve the problem of a possible lunar core.

    Propagation of Rayleigh Waves in the Earth (1937)

    Geophysical journal international 4 (1937), S. 0

    Notes: The propagation of Rayleigh waves in the Earth is investigated in the whole range of periods T from about 10s up to one hour. Three methods are necessary in order to cover this range of periods effectively. The standard flat Earth method, with neglect of gravity, gives values for the phase velocity C correct to within I per cent up to T= 50s only, and for the group velocity U up to T= 250s. The method of the flattening of the Earth, with neglect of gravity, has the I per cent accuracy limits for C and U at 300 and 400, respectively. Inclusion of gravity effects in the flattening of the Earth approximation does not alter the above limits. For T 〉 300 (n 〈 25) one must determine the period T(n) of free oscillation of the Earth as a function of the order of the spherical harmonic n. This involves the solution of a system of differential equations of the sixth order, in which the gravitational effects are included. The wave penetrates appreciably into the core already at T= 600. Using the above three methods in their respective ranges of validity, we have evaluated C(T) and U(T) for (I) Bullen's Model B, (2) the Jeffreys-Bullen Model, as modified by Dorman, Ewing and Oliver, and (3) the Gutenberg Model. The observed Rayleigh group velocity data of Ewing and Press for T 〈 380s and the phase velocity data of Nafe and Brune for T 〈 300s agree with the values computed for the Gutenberg model, but not for the other models. This substantiates a previous conclusion reached by Takeuchi, Press and Kobayashi and by Dorman, Ewing and Oliver that the observed Rayleigh wave data provide evidence in support of Gutenberg's lowvelocity layer. The few observed Rayleigh group velocities between T= 400 and 600 are substantially lower than the theoretical values for all the three models.

    On the aplanarity of the nitrate group in inorganic crystals (1983)

    Description / Table of Contents: Zusammenfassung Die geometrische Analyse sorgfältig verfeinerter Kristallstrukturen anorganischer Nitrate zeigt, daß schwache Aplanaritäten dieser Gruppe — d. h. solche mit einem Abstandd des Stickstoffs von der Ebene der drei Sauerstoffe bisd ∼ 0,02 Å — keineswegs seltene Ausnahmen sind. Viel größere Aplanaritäten wurden zwar beschrieben oder ergeben sich aus den veröffentlichten Strukturdaten; alle Beispiele mitd〉0,05 Å scheinen jedoch einer Bestätigung zu bedürfen.
    Notes: Abstract Geometric analysis of carefully refined inorganic nitrate crystal structures shows that weak aplanarities of the NO3-group, i.e. with a distanced of the nitrogen atom from the plane defined by the three oxygen atoms up tod∼0.02 Å, are by no means rare exceptions. Much larger aplanarities have been reported to occur in some crystal structures or follow from the published structure data, but all examples withd〉0.05 Å seem to need confirmation.

    The motion mechanics of Nitella filaments (Cytoplasmic streaming): Their imitation in detail by screw-mechanical models (1981)
    New York, NY : Wiley-Blackwell

    Notes: Our knowledge about the actin-containing characean filaments on the basis of light and electron microscopical investigations is reviewed. Dynamic filamentous networks, known already from isolated droplets, were detected in Nitella rhizoidal cells using light microscopical techniques. Earlier light microscopic observations in cytoplasmic droplets are confirmed and complemented by new model experiments with rotating helices. The motile phenomena occurring at the filament bundles (ring formation, wave propagation, particle translocation, net dynamics, rolling motions, formation of side arms) can, in this way, be imitated in detail. Thus, the concept of cytoplasmic streaming as a translocation along bundles of rapidly rotating helical filaments is supported. In order to explain unidirectional cytoplasmic streaming, a periodic winding up and unwinding of fine filaments is postulated by which ions are periodically bound and displaced. The formation of side arms which is favored during unwinding results in a screw-mechanical different behavior of the filaments in the two directions of rotation and therefore causes permanent particle transport in one direction.
