    Notes: In magnetic field analysis, designers are interested in the magnitude of magnetic flux density. It is common practice to use vector potential as an unknown variable and then differentiate it to obtain the magnetic flux density. This paper uses the magnetic flux density directly as an unknown variable. The formulation of this new method and its application to two-dimensional and axisymmetrical magnetic fields are explained and illustrated. The calculated error of the magnetic flux density by the new technique is compared with that obtained by the traditional finite element method for a model of known solution. The comparison shows that the new method is capable of producing better results than the traditional one in terms of computation time and accuracy. Furthermore, the proposed technique will be useful for the calculation of three-dimensional fields and eddy-current problems.

    Notes: Summary An attempt was male to identify Lucifer Yellow-labeled neurons in the rat supraoptic nucleus as vasopressin-containing neurons, by means of a combination of immunoperoxidase histochemistry and iontophoretic single cell-injection. We came to the conclusion that the fluorecent dye does not diminish the immunoreactivity of vasopressin in the magnocellular neurons. This newly developed method, along with its modifications, should prove to be quite useful for electrophysiological and morphological studies on the neuropeptide-releasing neurons in the mammalian neuroendocrine system.

    Notes: Summary Six strains of a new serological type of bovine rhinovirus were isolated in primary calf kidney cell cultures from nasal swab specimens of cattle with acute respiratory disease in Japan. They are serologically indistinguishable from one another and show no cross reaction with bovine rhinovirus types 1 and 2. We propose that the new isolates classified as bovine rhinovirus serotype 3.

    Notes: Summary Transmissible gastroenteritis virus grown in primary swine kidney cell cultures agglutinated erythrocytes from chicken, guinea pig and cattle but not erythrocytes from mouse and goose. The optimal incubation temperature was at 4°C. The hemagglutination (HA) reaction was inhibited by specific antiserum. Some factors involved in the HA and HA-inhibition (HI) were investigated and standard HA and HI tests were established. HI antibody titers of individual pig sera showed a significant positive correlation with their neutralizing antibody titers.

    Description / Table of Contents: Zusammenfassung Die Existenz von Ionen-Aggregaten in Äthylen-Acrylsäure-Mischpolymerisaten, die durch Mangan-acetat und Nickel-acetat neutralisiert wurden, wurden durch dielektrische Messungen im Temperaturbereich von -180 bis 80 °C und für einige Frequenzen zwischen 30 Hz und 100 kHz, studiert. Dieβ′- undγ-Relaxationsprozesse wurden beobachtet, die durch die Mikro-Brownschen Molekülbewegungen im höheren Temperaturbereich vonT g und durch lokale Molekülbewegungen im tieferen Temperaturbereich vonT g verursacht werden. Die Veränderung in Intensität und Relaxationstemperatur für die beiden Relaxationsprozesse mit dem Grad der Neutralisation deutet auf die Bildung von Ionen-Aggregaten in Bereichen höherer Neutralisation als einem Wert zwischen 3.3 und 14% für das Mn(II)-Salz und als 14% für das Ni(II)-Salz an. Diese Bildung von Ionen-Aggregaten wurde ebenso durch Elektronenspinresonanz (ESR) und durch Kleinwinkel-Röntgenstreuung (KWRS) nachgewiesen. Die ESR-Spektren in den Mn(II)-Salzen zeigen sechs Absorptionen bei 14% Neutralisation und eine Absorption bei 62%. Die KWRS deutet auf die Existenz von Ionen-Aggregaten hin, deren Durchmesser ungefähr 27 Å für das Mn(II)-Salz und 19–23 Å für das Ni(II)-Salz bei höherer Neutralisation als 14% ist.
    Notes: Summary The existence of ion-clusters in ethylene-acrylic acid copolymers (mole% of acrylic acid is 9.3) neutralized with manganese(II) and nickel(II) acetates, respectively, was studied by dielectric measurements in the temperature range of −180 to 80 °C at several frequencies between 30 Hz and 100 kHz. Theβ′ relaxation due to a micro-Brownian molecular motion aboveT g and theγ relaxation due to a local molecular motion belowT g were observed. Variation in the magnitude and the relaxation temperature of the two relaxations with degree of neutralization by manganese/nickel acetate suggest the formation of ion-clusters in the higher degrees of neutralization above a value between 3.3 and 14% for the Mn(II) salts and above about 14% for the Ni(II) salts. Furthermore, this formation of ion-clusters was evidenced by electron spin resonance and small angle X-ray scattering studies. The ESR spectra for the Mn(II) salts exhibited six peaks at 14% of degree of neutralization and one peak at 62%. This indicates the existence of ion-clusters at 62%. The small angle X-ray scatterings suggested the existence of ion-clusters of diameter of about 27 Å for the Mn(II) salts and 19–23 A for the Ni(II) salts, at the high degrees of neutralization above 14%.
