    Description / Table of Contents: Zusammenfassung Es wird berichtet über sonographische Routinekontrollen nach Nierentransplantation bei 72 Patienten. Die Kontrollen sollten in erster Linielokale Komplikationen im Operationsgebiet erfassen und diese gegebenenfalls von einer Abstoßungsreaktion bei nicht eindeutigen klinischen Befunden abgrenzen. Bei den 72 Patienten wurden insgesamt 295 Sonographien durchgeführt. Es fanden sich 22 lokale Komplikationen, von denen 15 im klinisch noch stummen Stadium sonographisch erfaßt wurden. Diese Patienten konnten dann frühzeitig einer chirurgischen bzw. urologischen Behandlung zugeführt werden. Aufgrund dieser Ergebnisse erscheint uns die routinemäßige sonographische Kontrolle des Nierentransplantates zur frühzeitigen Erfassung einer lokalen Komplikation im OP-Gebiet gerechtfertigt, während nuclearmedizinische Methoden bei der Frage nach vasculären Veränderungen und bei gestörter Transplantatfunktion eingesetzt werden sollten.
    Notes: Summary Routine follow-up examinations by ultrasonography after renal transplantation were performed in 72 patients from December 1978 until March 1980. The aim of these controls was to recognizelocal complications in the area of surgery in order to differentiate from a rejection reaction in patients with unclear clinical symptoms. 22 out of 72 patients had local complications. 15 out of those 22 were detected by ultrasound in a state without clinical symptoms, which then could be treated by surgical or urological intervention. We therefore believe that routine follow-up examinations after renal transplantation by ultrasound are indicated in order to recognize local complications. Nuclear procedures should be employed if alteration of blood flow or disturbed function of the transplanted kidney are considered.

    Description / Table of Contents: Im Rahmen der BIXON-ZWANZIG-Theorie wird die Dynamißk von Polymerlösungen unter Berücksichtigung voi hydrodynamischen and excluded-volume-Wechselwirkungen konsistent behandelt. Die Ergebnisse bestätigen die wesentlichsten Eigenschaften des “blob” -Bildes, d. h. den Einfluß der nicht-uniformen Ausdehnung der Kette auf die Relaxationszeiten und die Intrinsic-Viskosität, unterscheiden sich im Detail jedoch von den Ergebnissen von DAUD und JANNINK sowie WEILL und DES CLOIZEAUX. Entgegen den Voraussagen wird ein zweites Plateau in [η(ω)] nicht beobachtet.
    Notes: The dynamics of polymer solutions are consistently treated by the BIXON-ZWANZIG theory including both hydrodynamic and excluded volume interactions. The results confirm generally the essential features of the “blob” picture in polymer dynamics, i.e. the influence of non-uniform chain expansion on the relaxation time spectra and the intrinsic viscosity, but differs in detail from results by DAOUD and JANNINK and WEILL and DES CLOIZEAUX. Especially no second plateau in [η(ω)] is observed.

    Description / Table of Contents: The optimized ROUSE-ZIMM-theory by BIXON and ZWANZIG is used to derive consistently viscoelastic relaxation times of chain models including the hydrodynamic interaction and excluded volume. The intrinsic viscosity is calculated on the basis of these relaxation time spectra.
    Notes: Auf der Basis des von BIXON und ZWANZIG begründeten optimierten ROUSE-ZIMM-Modells werden viskoelastische Relaxationszeiten für Modellketten unter Berücksichtigung des excluded-volume-Effecktes und der hydrodynamischen Wechselwirkung in konsistenter Weise berechnet. Die Eigenviskosität wird auf der Grundlage der Relaxationszeit-spektren berechnet.

    Gel permeation chromatograms: Approximate relation of line shape to polymer polydispersity (1965)

    Notes: Characteristics of gel permeation chromatograms are investigated for three molecular distribution functions assuming a linear relation between elution volume and the logarithm of solute molecular weight. The average molecular weight, Mgpc, determined by the peak position of a chromatogram lies between the Mw and Mn for a polydisperse polymer.

    Polydisperse polymers with random trifunctional branching. II. Weight-averaging of chosen molecular size-dependent functions and a restatement of the approximate distribution function (1965)
    New York : Wiley-Blackwell

    Notes: The product gzbZa is weight-averaged over the distribution of molecular species in a polydisperse polymer possessing randomly distributed trifunctional branch points. This permits comparison between branched and nonbranched polydisperse polymers of certain physical properties that depend upon the relative degree of polymerization, z, and upon the ratio of branched to nonbranched molecule mean-square radii, g = Rbr2/Rl2. Values of a, b, and γ (a branching index) are chosen for specific physical reasons and the computed ratios, \documentclass{article}\pagestyle{empty}\begin{document}$ (1 - \gamma )^a \int_0^\infty {g_z ^b z^a } W_z dz/\int_0^\infty {z^{a + 1} e^{ - z} dz} $\end{document} are tabulated. The distribution function for the polydisperse polymer possessing randomly distributed trifunctional branch points is restated in terms of a modified Bessel function of the first kind. This form is of use since properties of the Bessel function are known and the tabulated values of this function are generally available.

    Continuous wave stimulated Raman spectroscopy of the ν1 band of natural GeH4 (1982)

    Notes: The ν1 band of natural germane (GeH4) has been recorded using a continuous wave stimulated Raman experiment which we describe in this paper. The resolution is about 0.005 cm-1 at 10 Torr pressure. In the first stage of the analysis, the Raman lines were identified thanks to the recent study of the ν1 and ν3 bands made by Lepage, Champion and Robiette. In the second stage, the stimulated Raman data were combined with the infrared data to refine the excited state constants of the isotopic species 70GeH4, 72GeH4 and 74GeH4.
