    The flare-related depression of the noise storm on May 5, 1978 (1982)

    Notes: Abstract Though a number of flares is capable to trigger the emission of a noise storm, in some other rare cases flares may also lead to a depression of the radio flux of a pre-existing noise storm. Details of this phenomenon are demonstrated at the flare of May 5, 1978 which can be regarded as an instructive example. Using extensive observations during the solar cycle No. 20 a number of further noise storm depressions could be detected whereas chance coincidences with flares could be ruled out by a statistical treatment. Possible mechanisms related to the noise storm depression effect are briefly discussed.

    α1 (Pi) types and subtypes in the Tyrolean population (1983)
    Springer
    Human genetics 〈Berlin〉 63 (1983), S. 193-194 
    Details
    ISSN: 1432-1203

    Topics: Biology , Medicine
    Notes: Summary Since nine patients with infantile liver cirrhosis or hepatopathy associated with the Pi ZZ phenotype had been observed in recent years in the Children's Hospital of the University of Innsbruck, Tyrol, the distribution of the Pi types and the PiM subtypes was determined in the Tyrolean population. Apparently healthy blood donors (868) from different regions of Tyrol were examined. Isoelectricfocusing was used for classification of Pi types. The frequency of the allele Piz was 0.0138, which corresponded to the range observed in other Middle European populations. The frequencies for the suballeles of PiM were PiM1=0.7062, PiM2=0.1480, and PiM3=0.1037. PiS had a frequency of 0.0225, the other rare alleles occurred with a combined frequency of 0.0058.

    A two-component model of impulsive microwave burst emission consistent with soft and hard X-rays (1977)

    Notes: Abstract A two-component (core-halo) emission model has been applied reconciling hard and soft X-ray burst emissions with the microwave burst radiation. The core region is represented by a nonthermal energy distribution (Maxwellian+power law tail) and assumed to be surrounded by a thermal halo. Parameters characterizing the energy distribution and emission measures have been derived numerically from soft and hard X-ray measurements. Using an artificial magnetic field model the microwave flux spectrum has been calculated on the basis of gyro-synchrotron emission and absorption by solving the equation of radiation transfer along the ray trajectories. Open parameters were used to adapt the spectrum to the radio measurements. Thus probable informations about the most appropriate magnetic field parameters as well as about the time- and frequency- dependent source diameters (yielding growth velocities of the core region during the impulsive phase) are deduced for the burst of 1972 May 18 as an example. A fit of the observed spectrum at the burst maximum is consistent with a magnetic field of 150O G at the core centre decreasing up to about 40 G at the top of the halo at a height of 50 000 km above the centre, a core density of 1010 cm−3 decreasing to 109 cm−3 at the outer halo boundary, and a core diameter of 15 000 km (∼]20″). Due to the simple geometry and emission process adopted,- the model refers primarily to special impulsive bursts. For the representation of broad band microwave bursts, e.g. type IV μ, events, a more complex source geometry and/or other variants of the emission mechanism must be invoked.
