    Notes: Abstract The adsorption of C60 molecules on the surface of a rhenium ibbon heated to 1800 K is investigated quantitatively. It is found that the C60 molecules are adsorbed without reflection and then dissociate, and the carbon formed in the process is dissolved in the bulk of the rhenium to the limit of solubility. Then a graphite monolayer forms on the rhenium surface, and the dissociation of the C60 molecules stops. It is shown that the C60 molecules can be used as an effective carbonizing object on metals in ultrahigh vacuum.

    Notes: Strains in HgTe/Hg0.1Cd0.9Te superlattices grown on (211)B Cd0.96Zn0.04Te substrates have been investigated by high-resolution x-ray diffraction. The lattice mismatch, the tensile as well as the shear strain have been obtained by measuring symmetric and asymmetric diffraction profiles in different azimuths. These measured strain parameters are then used to extract from the diffraction profiles the chemical composition and thickness of individual layers constituting the superlattice period. The analysis is based on the theory of elasticity, in which the strain tensor components in partially relaxed epitaxial layers are calculated by minimizing the strain energy density. The method presented in this article is valid for the strain analysis of partially relaxed epitaxial layers grown on arbitrarily oriented surfaces. © 1997 American Institute of Physics.

    Notes: Strain in a HgTe/Hg0.1Cd0.9Te superlattice grown on (112)B Cd0.96Zn0.04Te substrate has been investigated by x-ray reciprocal space mapping. It is shown that the shear strain in the superlattice results in monoclinic unit cells, whereas the cubic symmetry of the substrate is retained. The reciprocal lattice points of the superlattice are shifted by the shear strain such that the conventional analysis fails to interpret them correctly. Instead, reciprocal space maps should be constructed for two azimuths in opposite directions and analyzed simultaneously in a coordinate system with nonorthogonal axes. The shear strain is obtained from the angle between the [111] directions of the superlattice and the substrate. After a position correction taking the measured shear strain into account, longitudinal strains are calculated with conventional methods. © 1997 American Institute of Physics.

    Notes: The haemolysis of sea bass Dicentrarchus labrax red blood cells (RBC) was initiated by tert-butyl-hydroperoxide (t-BHP). The onset of the haemolytic process was accelerated by increasing t-BHP concentration. This process was preceded by a drop in the RBC glutathione content followed by the production of lipid peroxidation products. Also t-BHP induced DNA fragmentation in RBC nuclei as measured by COMET assay. The addition of the antioxidant Trolox C® dose-dependently delayed the onset of both lipid peroxidation and haemolysis, and protected GSH stores against t-BHP-induced depletion. DNA fragmentation was also pre-vented by Trolox C®. These results indicate that t-BHP induces haemolysis in sea bass RBC through the induction of oxidative stress. Such a simple model could prove useful for both fundamental and applied studies on marine fish antioxidant mechanisms.

    Description / Table of Contents: Zusammenfassung Der folgende Aufsatz zeigt auf, daß programmierte sequentielle Graph-Grammatiken dazu benutzt werden können, die Veränderung hoher Zwischencodes zu spezifizieren, die im Kontext einer Software-Entwicklungsumgebung auftreten, deren Werkzeuge alle inkrementell und syntaxgesteuert arbeiten. Wir legen in diesem Aufsatz mehr Wert auf die Erläuterung einer systematischen Vorgehensweise, um die Spezifikation zu erhalten, als auf die detaillierte Abhandlung der Spezifikation selbst. Somit kann dieses Papier auch als ein Ansatz zu einem „Spezifikations-Engineering” mit Hilfe von Graph-Grammatiken angesehen werden. Der Ansatz wird maßgeblich beeinflußt von der Syntaxdefinition der zugrundeliegenden formalen Sprache für das Programmieren im Kleinen bzw. für das Modulkonzept etc. einerseits und andererseits von der Vorstellung der Form der Benutzerschnittstelle.
    Notes: Abstract The following paper demonstrates that programmed sequential graph grammars can be used in a systematic proceeding to specify the changes of high level intermediate data structures arising in a programming support environment, in which all tools work in an incremental and syntax-driven mode. In this paper we lay stress upon the way to get the specification rather than on the result of this process. Therefore, we give here some approach to “specification engineering” using graph grammars. This approach is influenced by the syntactical definition of the underlying language for Programming in the Small, the module concept etc. to be supported on one side but also by the idea of the user interface.
