    Notizen: Summary The compositional distributions of coding sequences and DNA molecules (in the 50-100-kb range) are remarkably narrower in murids (rat and mouse) compared to humans (as well as to all other mammals explored so far). In murids, both distributions begin at higher and end at lower GC values. A comparison of homologous coding sequences from murids and humans revealed that their different compositional distributions are due to differences in GC levels in all three codon positions, particularly of genes located at both ends of the distribution. In turn, these differences are responsible for differences in both codon usage and amino acids. When GC levels at first+second codon positions and third codon positions, respectively, of murid genes are plotted against corresponding GC levels of homologous human genes, linear relationships (with very high correlation coefficients and slopes of about 0.78 and 0.60, respectively) are found. This indicates a conservation of the order of GC levels in homologous genes from humans and murids. (The same comparison for mouse and rat genes indicates a conservation of GC levels of homologous genes.) A similar linear relationship was observed when plotting GC levels of corresponding DNA fractions (as obtained by density gradient centrifugation in the presence of a sequence-specific ligand) from mouse and human. These findings indicate that orderly compositional changes affecting not only coding sequences but also noncoding sequences took place since the divergence of murids. Such directional fixations of mutations point to the existence of selective pressures affecting the genome as a whole.

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung QuarternäreHeusler-Legierungen der Zusammensetzung (Ni1−x Cu x )2MnSn wurden über den Konzentrationsbereichx=0–1 hergestellt. Alle waren einphasig und zeigten L 21-Struktur. Magnetische Messungen wurden sowohl im ferromagnetischen als auch im paramagnetischen Bereich durchgeführt. Sie ergaben für Mn, das einzige Atom das in dieser Art vonHeusler-Legierungen ein Moment zeigt, den üblichen Wert von ca. 4 µB und ein ihm entsprechendes μeff im paramagnetischen Bereich. Ein flaches Minimum derCurietemperatur kann mit Hilfe von di-dl-Wechselwirkung erklärt werden.
    Notizen: Abstract QuarternaryHeusler alloys of composition (Ni1−x Cu x )2MnSn were prepared withx=0–1. They were all single phased with L21 structure. Alloys were investigated by magnetic measurements. For Mn, the only atom carrying a moment in this kind ofHeusler alloys, the usual value (∼4 µB) was found and a corresponding μeff in the paramagnetic region. A shallow minimum of theCurie temperatures can be explained on the basis of di-dl interaction.

    Notizen: Abstract From our interpretation of the Bouguer gravity and aeromagnetic anomalies in south-east Scotland, we conclude that a massive granite batholith underlies the greater part of the eastern Southern Uplands. The granite model which we computed earlier from gravity anomalies in the Tweeddale area fits the observed magnetic anomalies closely, if a normal magnetization of 0.095 A m−1 is assigned, similar to values found for exposed local granites. Further gravity modelling shows that, apart from the Tweeddale boss, the granite shallows to less than 1 km near Lammer Law in East Lothian and extends north of the Lammermuir Fault. A model for the East Lothian volcanics was computed from their aeromagnetic anomalies, then their gravitational effect was combined with that estimated for the Devonian and Carboniferous sediments and the result stripped off the observed gravity field. The residual gravity anomalies were used to generate a two-dimensional model for the granite north of the Lammermuir Fault. The expected tectonic consequences of a massive granite batholith in the eastern Southern Uplands are compared with the known development of faults and sedimentary basins around its margins.

    Notizen: Abstract The MINDO/SR method is used to study surface properties such as the work function, heat of adsorption and magnetic moment as a function of hydrogen coverage. A good correlation between theory and experiment is found. Furthermore, a qualitative analysis of surface geometry changes due to hydrogen chemisorption is presented.

    Notizen: Summary Distribution of glycogen particles in semithin and ultrathin sections of biopsy samples from human muscles subjected to either short- or long-term running were investigated using PAS and Periodic Acid-ThioSemiCarbazide-Silver Proteinate (PA-TSC-SP) staining methods. Glycogen particles were predominantly found immediately under the sarcolemma or aligned along the myofibrillar Iband. After long-term exhaustive exercise type-1 fibers with a few or no glycogen particles in the core of the fibers were frequently observed. The subsarcolemmal glycogen stores of these “depleted” type-1 fibers were about three times as large as after exhaustive short-time exercise. Another indication of utilization of subsarcolemmal glycogen stores during anaerobic exercise was that many particles displayed a pale, rudimentary shape. This observation suggests fragmental metabolization of glycogen. Thus, depending on type of exercise and type of fiber differential and sequential glycogen utilization patterns can be observed.
