    Notes: Ordering of Cu and In atoms in near-stoichiometric CuInS2 epitaxial films grown on Si (111) by molecular beam epitaxy was studied by transmission electron microscopy. Nonchalcopyrite ordering of the metal atoms in CuInS2 is observed, which is identified as CuAu-type ordering. Sharp spots in electron diffraction patterns reveal the ordered Cu and In atom planes alternating along the [001] direction over a long range. High-resolution electron microscopy confirms this ordering. The CuAu-ordered structure coexists with the chalcopyrite ordered structure, in agreement with theoretical prediction. © 1998 American Institute of Physics.

    Notes: CdSe quantum dots on ZnSe, grown by molecular beam epitaxy and formed during reorganization of an initially uniform film by thermal activation, are microstructurally elucidated in cross section and plan view, using transmission electron microscopy. In diffraction contrast, an almost uniform wetting layer is clearly visible. Dark contrast features with a distinctly larger extension into growth direction mark the location of quantum dots. Individual quantum dots can be identified in high-resolution imaging both by lattice expansion and contrasts arising from their strain fields. Plan-view images show the coexistence of two classes of quantum dots with an average lateral size of ≤10 nm (area density 100 μm−2) and 10–50 nm (20 μm−2), respectively. The shape of the larger entities is pyramidlike. © 1998 American Institute of Physics.

    Notes: Schluss Zusammenfassend kann man also als Ergebnis der Untersuchungen folgendes aufstellen: 1. Eine günstige Einwirkung einer Behandlung mit Alttuberkulin, in der Weise wie sie etwa in der Humanmedizin angewendet wird, konnte ich bei der Impftuberkulose des Meerschweinchens ebensowenig wie Haupt und frühere Untersucher beobachten, weder was die Lebensdauer noch was die klinischen und anatomischen Veränderungen betrifft. 2. Behandlung mit ziemlich grossen Dosen Rosenbachschen Tuberkulins scheint in solchen Fällen, die schon an sich zu sehr chronischem Verlauf neigen, noch eine weitere Verlangsamung des Krank heitsablaufes herbeiführen zu können, also immerhin günstig, wenn auch nicht heilend wirken zu können. 3. Beide Mittel werden von den Tieren in grossen Mengen vertragen. Eine immunisierende Wirkung haben beide nicht. Selbstverständlich berechtigt dieses Ergebnis keineswegs dazu, etwa bei der menschlichen Tuberkulose die Versuche mit dem Rosenbachschen Präparat aufzugeben, ebenso wie man ja das Alttuberkulin trotz seiner Unwirksamkeit gegen die Meerschweinchen tuberkulose in der Humanmedizin mit Nutzen verwendet.

    Description / Table of Contents: Summary 1. The phenylalanine tolerance was estimated after intravenous injection of L-phenylalanine in premature newborns, mature newborns, infants and normal adults. The elimination of phenylalanine from the blood followed the pattern of a monomolecular reaction. The rate of elimination was, therefore, chosen for the comparison of the degree of tolerance. 2. The tolerance of phenylalanine was markedly reduced in most of the prematures; the same was found in some of the mature newborn infants. Compared with the tolerance in adults there was no decrease of phenylalanine tolerance in most of the mature newborns and in all infants. 3. The relation of phenylalanine tolerance to the activity of phenylalanine hydroxylase and to the development of the phenylalanine hydroxylase system was discussed.
    Notes: Zusammenfassung 1. Die Phenylalanin-Toleranz wurde vergleichend bei Frühgeborenen, reifen Neugeborenen, Säuglingen und Erwachsenen bestimmt. Die Untersuchung erfolgte nach intravenöser Injektion von L-Phenylalanin. Die Elimination von Phenylalanin aus dem Blut erfolgte entsprechend einer Exponentialfunktion. Zur Beurteilung des Toleranzgrades wurde die Eliminationshalbwertszeit gewählt. 2. Die Phenylalanin-Toleranz war bei den meisten Frühgeborenen herabgesetzt. Bei reifen Neugeborenen kamen Toleranzverminderungen vor; sie waren jedoch wesentlich seltener. Die meisten Neugeborenen und alle Säuglinge zeigten eine Phenylalanin-Toleranz, die der beim normalen Erwachsenen entspricht. 3. Es werden die Beziehungen diskutiert, die zwischen der Phenylalanin-Toleranz und der Aktivität der Phenylalaninhydroxylase bestehen, und es wird auf die bei neonatalen Tieren beobachteten Aktivitätsverminderung des Phenylalaninhydroxylase-Systems hingewiesen.

    Notes: [Auszug] The purpose of the investigation described in this communication was to estimate the rate of elimination of phenylalanine from the blood. We tested seventeen healthy adults, nine heterozygotes, and six phenylketonurics. First we obtained a fasting specimen of capillary blood by means of a ...

    Notes: The paper describes the Rossendorf beamline (ROBL) built by the Forschungszentrum Rossendorf at the ESRF. ROBL comprises two different and independently operating experimental stations: a radiochemistry laboratory for X-ray absorption spectroscopy of non-sealed radioactive samples and a general purpose materials research station for X-ray diffraction and reflectometry mainly of thin films and interfaces modified by ion beam techniques.
