    Notes: Gold Schottky-barrier diodes (SBDs) were fabricated on vapor-phase-grown single-crystal ZnO. Deep-level transient spectroscopy, using these SBDs, revealed the presence of four electron traps, the major two having levels at 0.12 eV and 0.57 below the conduction band. Comparison with temperature-dependent Hall measurements suggests that the 0.12 eV level has a temperature activated capture cross section with a capture barrier of about 0.06 eV and that it may significantly contribute to the free-carrier density. Based on the concentrations of defects other than this shallow donor, we conclude that the quality of the vapor-phase-grown ZnO studied here supercedes that of other single-crystal ZnO reported up to now. © 2002 American Institute of Physics.

    Notes: A complete ab initio treatment is applied to the autoionization process in the He*(2s 3S)+Li(2s 2S) collisional complex. Feshbach projection based on orbital occupancy, implemented in a multireference configuration interaction (MRCI) code, defines the resonance state and provides the entrance channel potential curve as well as all pertinent information on the resonance–continuum coupling. The l-dependent coupling elements in local approximation are obtained by projecting a compact one-electron function, named Penning molecular orbital (PMO), onto the wave function of the ejected electron with proper energy. The continuum wave function is obtained by coupled channel calculations in the static-exchange approximation. A converged set of seven complex coupling matrix elements, used in the nuclear dynamics calculation based on a complex Numerov algorithm, fully describes the electron angular momentum transfer. The calculated angle-dependent spectra, as well as the total, angle-, and energy-integrated ionization cross sections agree well with available experimental data. © 2000 American Institute of Physics.

    Notes: Sub-Doppler laser spectroscopy of the A 2E″←X 2E′ band of Li3 shows well-resolved and characteristic hyperfine structures of rovibronic transitions which can be explained in all detail by the interplay between the underlying Fermi-contact interaction, the symmetry species of the rovibronic states and the Coriolis coupling of rotational and pseudorotational motions. Ab initio calculated electron spin densities reproduce the observed line splittings to within 3%. In this Jahn–Teller distorted molecule magnetic equivalence of identical nuclei is strictly valid only for rovibronic states of A symmetry. However, it also holds for rovibronic states of E symmetry if they are of pure A vibronic origin, and it is enforced for many E states of pure E vibronic origin by Coriolis coupling. In contrast, those transitions which involve states with dominant Kc=0 rotation functions and/or with strong vibronic E/A mixing show significant changes in the hyperfine patterns due to magnetic inequivalence, sometimes called "hyperfine doubling." © 2001 American Institute of Physics.

    Notes: During the critical early postnatal period, the development of lymphatic organs, being the major structural components of the immune system, progresses rapidly. In this context, the growth kinetics and growth rates of Peyer's patches, tonsilla veli palatini, lymphnodes (lc. mesentericum craniale and lc. bronchale), spleen and thymus were investigated in German landrace piglets from birth until 2 weeks of age. The weight of all these organs increased faster than body weight but regression analysis revealed remarkable differences in growth kinetics and growth rates. The lymphoepithelial organs (Peyer's patches, tonsilla veli palatini) had low growth rates at birth (∼10%/day) that increased continuously until 2 weeks, while lymphnodes and spleen exhibited constant high growth rates (∼40%/day). Small intestinal lymphnodes alone showed biphasic growth kinetics which could be attributed to colostrum absorption. The growth kinetics of the thymus included a point of inflexion at the end of the first week. The differences in growth kinetics and growth rates are discussed with regard to their immunobiological relevance.

    Description / Table of Contents: Zusammenfassung An einem experimentell erzeugten Hornhautödem bzw. an normalen Hornhäuten von Kaninchen wird die Wirkung von Glucose- und Glycerinlösungen unterschiedlicher Konzentration verglichen. Als Maß des Quellungsgrades dient die Hornhautdicke, die mit einem Meßgerät eigener Anfertigung in Anlehnung an das Gerät von Jäger registriert wird. Es wurden folgende Ergebnisse erzielt: 1. Die normale Kaninchenhornhaut konnte sowohl durch Glucose- als auch durch Glycerinlösung bis etwa auf 50% der Normaldicke entquollen werden. 2. Glucoselösungen wirkten auf das experimentell erzeugte Hornhautödem stärker entquellend als glycerinlösungen gleicher Osmolarität. 3. Eine geringe regenerationsfördernde Wirkung auf das Corneaendothel konnte bei Glycerinbehandlung deutlicher nachgewiesen werden als bei Glucoselösung vergleichbarer Konzentration. Aus den Ergebnissen folgt, daß sich Glycerin ebenso wie Glucose zur Entquellung eines Hornhautödems eignet. Eine Entscheidung über die Verwendbarkeit von Glycerinlösung beim Hornhautödem des Menschen erfordert weitere Untersuchungen.
    Notes: Summary The effect of glucose and glycerine solutions of different concentrations was examined on a corneal oedema produced experimentally and on normal corneae of rabbits, respectively. The swollen cornea was measured by means of a home-made device similar to that described by Jäger! The following results were obtained: 1. By instillation of glucose as well as glycerine solutions it was possible to reduce the thickness of the normal rabbit cornea to 50% of the original value. 2. Glucose solutions showed a more dehydrating effect on the experimentally produced corneal oedema than glycerine solutions of the same osmolarity. 3. A slight effect favouring the regeneration of the corneal endothelium could be seen more distinctly after treatment with glycerine than after the instillation of glucose solutions of comparable concentrations. It is concluded that glycerine and glucose are equally suitable for dehydrating a corneal oedema. Further investigations, however, are necessary before glycerine solutions can be used in human corneal oedemata.

    Description / Table of Contents: Zusammenfassung Die vorliegende Arbeit schließt an unsere I. Mitteilung an und führt nach statistisch orientierter Auswertung der klinischen Befunde zu folgenden Ergebnissen: 1. Junge Wistar-Ratten (mittleres Körpergewicht 119 g) reagierten auf einmalige intracutane Injektion von 0,08–0,1 ml kompletten Freundschen Adjuvans zu 76,1% mit Arthritis, zu 79,5% mit Augenentzündungen, zu 51,6% mit Ohrknötchen und zu 58,7% mit Schwanzknoten. 2. Nach Latenzzeiten zwischen 1 und 80 Tagen trat bei 67,7% der untersuchten Augen eine Uveitis anterior auf. Bei 21 Tieren blieb sie auf ein Auge beschränkt. In 37 von 49 Fällen beidseitiger Affektion lagen zwischen dem Entzündungsbeginn von rechtem und linkem Auge Intervalle von 1–37 Tagen. 3. Bei 58 von 119 Augen (48,7%) mit einer Uveitis anterior kam es im Verlauf von 101–102 Tagen zu klinisch sicheren Remissionen. 35 Fälle mit einem, 14 mit zwei und 9 Fälle mit drei Rezidiven wurden beobachtet. Beginn. Dauer und Schweregrad der Schübe gleicher Ordnung sowie die Dauer entzündungsfreier Intervalle werden, abgestuft nach der Schubzahl der Verläufe, in Form arithmetischer Mittel angegeben. Remissionslose Entzündungen traten meist später auf und hielten länger an als die ersten Schübe rezidivierender Entzündungen. Die Entzündungsschübe I–III begannen jeweils in Abständen von etwa 2 Wochen, der Schub IV bereits nach einem Intervall von 8–9 Tagen. Eine Tendenz zu rascherem Abklingen in der Reihe aufeinanderfolgender Entzündungsschübe war nicht generell von einer Milderung der Symptome begleitet. 4. Mit der Arthritis als augenfälligstem Symptom der Adjuvans-Krankheit zeigten sich die Augenveränderungen eng, aber nicht zwingend, Ohrknötchen indessen als nahezu obligatorisch assoziiert. Als einziges Zeichen einer Adjuvans-Krankheit wurden Augenentzündungen dreimal häufiger beobachtet als Arthritis.
    Notes: Summary The present publication is a continuation of our first communication. A statistically orientated valuation of clinical findings leads to the following results: 1. Young Wistar rats (average body weight 119 g) responded to a single intracutaneous injection of 0.08–0.1 ml of Freund's complete adjuvant by developing several symptoms of adjuvant disease. 76.1% of the animals developed arthritis, 79.5% inflammations of the eyes and 51.6% and 58.7% respectively showed nodular alterations in external ears and tail. 2. After a latent period from 1 to 80 days 67.7% of the eyes examined developed iridocyclitic changes. In 21 animals inflammation was limited to one eyeball. In 37 out of 49 cases of bilateral affection the interval, between onset of inflammation in the right and the left eyes varied between 1 and 37 days. 3. During a period of 101–102 days clinically assured recidivations were demonstrated in 58 out of 119 eyes (48.7%) showing iridocyclitis. 35 cases showed one, 14 two and 9 cases three recidivations. Onset, duration and severity of batches of the same rank as well as the duration of intervals without inflammatory signs —graduated according to the number of batches per course—are stated as arith-metical means. Non-relapsing inflammations mostly began later and lasted longer than the first batches of relapsing inflammations. The inflammatory batches II and III started after an interval of 2 weeks, and the batch IV already after an interval of 8–9 days. A tendency to quicker improvement in the series of successive batches was not generally accompanied by a moderation of symtoms. 4. Eye lesions showed a close but no obligatory association with the arthritis as the most obvious symptom of adjuvant disease. The development of nodular changes in the external ears, however, seemed bound to the presence of arthritis. As the only sign of an adjuvant disease eye lesions were observed three times more frequently than arthritis.
