    Notes: Abstract Frescos and oil-paintings from the 15. and the beginning of the 16. century showing outbreaks of pests In the 15. and the beginning of the 16. century frescos and oil-paintings were created for catechetic purposes on which the Ten Commandments respectively their transgressions were confronted with the Ten Egyptian Troubles. Such paintings are still to be found in the church of the Holy Virgin at Lemgo, in the municipal church of Zierenberg (Kassel district), in the church at Nonnberg near Altoetting in Upper Bavaria, in the churcht at Werschling in Carinthia, in the municipal church at Friedberg in Hassia, in the St. Georges church at Dinkelsbuehl and in the conventual church at Benediktbeuern in Upper Bavaria. Naturally only this troubles are interesting here where calamities by vermins are presented. While in Lemgo, Zierenberg and far extending also in Dinkelsbuehl the vermins are shown more symbolic in a form of a standardized letter like on contemporary graphic designs and on older book-paintings, the vermins on the frescos at Nonnberg and on the paintings at Benediktbeuern are rendered full of life and natural. In regard to the paintings about the trouble of migratory locusts the artists of Nonnberg and Benediktbeuern have possibly produced their works under the impression of the invasion of locusts during the years from 1475 till 1477 in Tyrol, Styria and Venetia.

    Notes: Abstract The superconducting transition temperatureT c of a Nb3Sn diffusion wire has been studied as a function of low-temperature neutron irradiation (T=10 K).T c is observed to be essentially constant until the fast neutron dose φt (for neutron energiesE〉0.1 MeV) exceeds a value of 1018 n/cm2; after this valueT c decreases linearly with φt up to the maximum applied dose of 1.05×1019 n/cm2. Comparison with theory and other experimental data indicates that radiation-induced disorder is the primary mechanism for the observedT c changes.

    Notes: Abstract Damages by birds in the antique Damages by birds especially on young or on standing crops are known since the early antique. Cause of the damages were essentially the same species of birds which are also important ennemies of the farmer till to-day: daws, starlings, sparrows, throstles. From greater birds which could be dangerous mainly for the winter-corn are mentioned cranes and wild-geese. To prevent damages mostly the same simple methods were applied which play an important part not only till early modern times but also till to-day. Representations of damages by birds in a real sense are not present; at the most decorative paintings and sculptures permit some conclusions about observations in this direction.

    Notes: Abstract The scattering of conduction electrons by defects is described by a low-field transport relaxation timeτ k x . It depends on the electron wavevectork and on the direction of the electric fieldE/E, but not on the magnetic fieldH. From a discussion of Kohler's rule written in terms of the exact relaxation timeτ k * it follows that this approximation is very good for low values ofH/ρ, withρ being the resistivity forH=0. Assumingτ k x to be known, the linearized Boltzmann equation is solved by a Jones-Zener expansion up to termsH 3. For metals with cubic symmetry we derive simple formulae for the coefficients of transverse and longitudinal magnetoresistance and for the two leading terms of the Hall coefficientR(H)=R 0+R 2(H/ρ)2. Simplifications occur for aτ k with cubic symmetry and for metals with special Fermi surfaces. These formulae are used to interpret experimental results of the magnetic field dependence ofR(H) in Al(Ge) at 4 K. In this dilute aluminium alloyR 0 is highly positive andR 2 strongly negative. By irradiating a 3,000 ppm Al(Ge) sample with reactor neutrons at 4 K, an increasing concentration of self-interstitials and vacancies is added to the germanium impurities resulting in a decrease of bothR 0 and |R 2|. This is discussed in a three-group model of the Fermi surface of aluminium.

    Notes: Abstract The scattering of conduction electrons on dilute point defects in aluminium was investigated, for zero temperature, by pseudopotential calculations considering the realistic form of the Al Fermi surface (FS) and band structure. The 4-OPW wavefunctions, band velocities and FS curvatures were calculated for 1,300 pointsk on 1/48 (cubic symmetry element) of the FS. The scattering potentials were obtained as follows: for the impurities Ge, Mg, Zn, and Ga tabulated pseudopotentials were used and rescreened for the electron density of Al, the vacancy was treated as a missing Al atom and the [100] dumbbell interstitial as two Al atoms with a vacancy in between (always with strain field corrections). The scattering matrixP kk′ was obtained in first order Born approximation. The linearized Boltzmann equation was solved numerically by iteration, for zero magnetic field and for a reduced set of 109 points on 1/48 FS, to yield the anisotropic transport relaxation timesτ k and lifetimesτ k 0 . Theτ k were interpolated for the 1,300 points again and inserted into low-field FS integrals for the galvanomagnetic coefficients which depend sensitively on the details of the FS and the anisotropy ofτ k . Without any free parameter, our results agree very well with experimental data for the case of Ge, Mg, and Zn impurities, and less so for the homovalent Ga impurities and for the self-defects. The diffusion thermopower was also calculated.

    Notes: Abstract Spontaneous-fission and alpha-decay half-lives are calculated for even-even nuclei with the atomic numberZ=104–110. The results reproduce rather well the existing experimental data for these nuclei and predict rather large total lifetimes for nuclei even heavier than observed up to now. The latter is mainly due to a deformed shell at the neutron numberN=162–164, obtained in calculations.
