    Notes: Abstract  The cause of hypereosinophilia (EO) in hemodialysis (HD) patients is multifactorial and is felt to be a benign laboratory abnormality related to dialysis or uremia. Kimura disease (KD) is an angiolymphoid proliferative disorder of unknown etiology. Many cases are associated with nephrotic syndrome in children; however, it has seldom been reported in children on dialysis. We report here a 13-year-old boy who developed persistent EO and subsequent anemia after maintenance HD; he later developed KD. The atypical clinical manifestation of KD and its relationship to HD and erythropoietin hyposensitive anemia in this patient are discussed.

    Description / Table of Contents: A Mathematical Function for the Description of Charpy Impact TestsSo far there exists no satisfactory analytical expression for the description of the results of Charpy impact tests. A function is developed in this paper for the functional dependence of these data on temperature using the following assumptions:1Charpy impact test results follow linear functions for purely ductile and brittle fracture, respectively.2A mixed fracture mode exits over the whole temperature range.3The percentage ductile fracture increases with increasing temperature. The temperature-dependent rate of increase of the percentage ductile fracture follows a Gaussian distribution.The equation derived with these assumptions is capable of describing all results of Charpy impact tests. Examples of curves of absorbed energy, lateral extension and percentage shear fracture versus temperature are shown.
    Notes: Für die Beschreibung von Ergebnissen aus Kerbschlagbiegeversuchen gab es bisher keinen zufriedenstellenden analytischen Ausdruck. Unter den folgenden Annahmen wurde in dieser Arbeit eine Funktion für die Darstellung solcher Werte entwickelt:1Kerbschlagwerte für rein spröden bzw. rein duktilen Bruch folgen linearen Temperaturfunktionen.2Im gesamten Temperaturbereich liegt ein temperaturabhängiger Mischzustand des Bruches vor.3Der duktile Anteil am Bruch nimmt mit steigender Temperatur zu. Die temperaturabhängige Zuwachsrate dieses Anteils folgt einer Normalverteilung.Die mit diesen Annahmen abgeleitete Gleichung kann sämtliche Ergebnisse aus Kerbschlagbiegeversuchen beschreiben. Beispiele von AV-T-, Breitung-T- und nichtkristalliner Anteil-T-Kurven werden gezeigt.

    Description / Table of Contents: Shift vectors for the comparison of Cv-T-curvesIt is shown in this paper that a shift in the Cv-T-curves caused by mechanical or thermal treatment, or by irradiation with particles of high energy can be better described by a shift vector given by the inversion points of a functionally determined curve than with the currently used empirical criteria. Moreover, the shift of a whole curve can be described by a vector whose components are the shifts of all parameters used for the calculation of the curve.The resulting vector of a Cv-T-curve may, for instance, be connected functionally with the neutron fluence. This makes it possible to compute shift vectors.
    Notes: In dieser Arbeit wird gezeigt, daß die durch mechanische oder thermische Einwirkung oder durch Bestrahlung mit hochenergetischen Teilchen hervorgerufene Verschiebung von AvT-Kurven durch die Verschiebung des funktionell bestimmten Wendepunktes mit einem Verschiebungsvektor besser beschrieben werden kann als mit den bisher üblichen empirischen Kriterien. Darüber hinaus kann die Verschiebung der gesamten Kurve durch einen Vektor beschrieben werden, dessen Komponenten die Verschiebungen aller zur Berechnung der Kurven verwendeten Parameter sind.Der Ergebnisvektor einer Av-T-Kurve kann z. B. mit der Neutronenfluenz funktionell verknüpft werden. Dies ermöglicht die Berechnung von Verschiebungsvektoren.

    Notes: The miscibility of polycarbonate (PC) with poly(methyl methacrylate-co-cyclohexyl methacrylate) (PMCHM) and with poly(methyl methacrylate) (PMMA) was studied by nuclear magnetic resonance (NMR) 1H spin-lattice relaxation time in the rotating frame (1H T1p), differential scanning calorimetry (DSC), and transmission electron microscopy (TEM). A blend of PC/PMCHM (50/50 wt/wt) with the acrylic component PMCHM, a copolymer of PMMA and poly(cyclohexyl methacrylate) (80/20 wt/wt), shows only one T1p value, which indicates high miscibility in this blend. A blend of PC/PMMA (50/50 wt/wt) shows two 1H T1p values, which are similar to those of the homopolymers PC and PMMA. These results indicate high immiscibility. The “domain size” calculated from NMR results of the miscible blend PC/PMCHM is approximately 40 Å. The results of DSC and TEM are similar to the NMR results. However, TEM results show the presence of 3% PC domains in the PC/PMCHM blend, which are not seen by NMR or DSC. Those PC domains are approximately 500 Å. A strong intramolecular repulsion in the copolymer PMCHM and specific intermolecular interactions between PC and PMMA may explain the miscibility in the PC/PMCHM system. © 1994 John Wiley & Sons, Inc.
