    Notes: [Auszug] FOR many years, cosmologists have been intrigued by possibly coincidental relationships between physical constants of the microscopic and cosmic domains1. Examples of these are the approximate equality of such large dimensionless numbers as the ratio of the electromagnetic to the gravitational ...

    Boundary conditions in closed universes (1975)
    Springer
    General relativity and gravitation 6 (1975), S. 253-258 
    Details
    ISSN: 1572-9532
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract We consider the problem of a particle in a square potential well in a one-dimensional closed universe. Imposition of periodic boundary conditions on the wave function changes the usual discrete energy levels to narrow but finite energy bands. Effects on the properties of atoms in a closed universe are estimated to be undetectable.

    Trapped null geodesies in a rotating interior metric (1976)
    Springer
    General relativity and gravitation 7 (1976), S. 715-729 
    Details
    ISSN: 1572-9532
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract We consider trapped, null geodesies in an interior, rotating metric which matches the Kerr metric on a spheroidal surface. The interior metric is unphysical, but still useful for obtaining a qualitative understandng of the properties of the trapped, interior geodesies. We find, by numerical techniques, that the presence of rotation increases trapping for count-errotating orbits, but decreases it for corotating orbits.

    Ion association in solutions of dimethylthallium(III) hydroxide (1974)
    Springer
    Journal of solution chemistry 3 (1974), S. 553-561

    Notes: Abstract From studies of the specific hydroxide ion catalyzed decomposition of diacetone alcohol by dimethylthallium(III) hydroxide at 25°C, it is concluded that both ion pairs (dissociation constantK=0.090 mole-dm−3) and dimers (dimerization constantK d=1.5 dm3-mole−1) exist in aqueous solution.

    Diffusion of magnetic flux elements on a fractal geometry (1991)
    Springer
    Solar physics 135 (1991), S. 249-259 
    Details
    ISSN: 1573-093X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Recent observations have indicated that magnetic field elements are distributed on the Sun in fractal patterns with dimension D 〈 2. We suggest that the transport of magnetic field elements across the solar surface should be treated as diffusion on a fractal geometry. We review a semi-analytical, theoretical treatment of fractal diffusion. Comparison with observations of small-scale motions of solar magnetic flux concentrations indicates that fractal diffusion may be taking place with dimension in the range 1.3 to 1.8. It is shown that, compared to the predictions that would be made for two-dimensional diffusion, fractal diffusion in this range would lead to an increased level of in situ flux cancellation in decaying active regions by 7% to 35%. Other work in specialities outside of solar physics may be useful in explaining solar magnetic phenomena.

    ISSN: 1573-093X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A statistical analysis is made of the spatial distribution of umbral dots and photospheric granules. The dots and granules are more evenly spaced than random points, though dots mapped by different observers have different distributions.

    Properties of flares observed in the Mg i b2 line at 5172 Å (1983)
    Springer
    Solar physics 89 (1983), S. 341-353 
    Details
    ISSN: 1573-093X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Observations of emission in the Mgi b2 line at 5172 Å are presented for 13 flares. Also discussed are 3 flares which occurred in regions under observation but which showed no Mg emission. The Mg flare kernels resemble white-light flare kernels in their general morphology and location. Comparison of Mg filtergrams with magnetograms indicates that the Mg kernels occur at the feet of magnetic arches across neutral lines. Time-lapse Mg filtergram films indicate photospheric shearing motions near flare sites for several hours before flare onset. We have compared flare Mg emission with microwave and both hard and soft X-ray flare emissions. Examination at the time development of the 1981, July 27 flare shows that the microwave and X-ray bursts may be clearly related to the appearance of successive Mg flare kernels. We have also compared subjective, relative Mg flare importances with other flare emission measurements. For the full sample of flares, Mg importance is significantly correlated with hard and soft X-ray emission peaks, with X-ray ‘hardness’ (ratio of hard to soft peaks) and with the rise slope of soft X-ray bursts. The Mg importance does not correlate with the microwave peaks when the full sample of flares is used, but for the subset showing Mg emission there is significant correlation. No correlation with Hα importance was found. Our results suggest that Mg emission is associated with an impulsive component which may be absent from some flares. The San Fernando Observatory magnesium etalon filter system is described.

    Elaboration of the new magnetohydrostatic sunspot theory (double return flux model) (1983)
    Springer
    Solar physics 88 (1983), S. 117-135 
    Details
    ISSN: 1573-093X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract An extension of the recently formulated Return Flux Sunspot Model is presented. The basic equation for a Double Return Flux Sunspot Model is derived, and a pressure distribution and magnetic field are calculated. The possible topology of the magnetic structure and its thermodynamic consequences are discussed. The paper includes a magnetogram of a single round sunspot (9 August, 1981). The authors attempt to interpret the observational data for the vertical component of magnetic field of this sunspot on the basis of the Double Return Flux Model.
