    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: 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: 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: 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: Summary Seventy-six physicians, working on a German Mobil Resuscitation Unit, were examined by use of a modified Gottschalk-Gleser technique. The aim was to describe scores for anxiety, hostility and hope and to compare those to the values of a normal population. Physicians' sumscores differed from those of a normal population: Anxiety and hostility were significantly higher. Singlescores for death-, separation- and shame-anxiety were higher, those for injury-anxiety and diffuse anxiety were lower. Guilt anxiety did not differ. Scores for hostility outward open were the same, whereas hostility outward covered and inward were higher than in the normal population. Ambivalent hostility was the same. Scores for positive hope were significantly lower, those for negative hope the same than in the normal population. In conclusion we found three possible obstacles for resuscitating physicians in dealing with anxiety, hostility and hope: Compared to the normal population physicians seem to deal less with injury-, guilt- and diffuse anxiety. Dealing with hostility reveals mechanisms of repression, projection and turning hostility towards the own person. Compared to the normal population resuscitating physicians tend not to talk more about the hopelessness related to their work.
    Notes: Zusammenfassung 76 Ärzte eines Notarztwagensystems wurden mittels eines modifizierten Gottschalk-Gleser-Interviews untersucht. Dabei wurden Scores für Angst, Hoffnung und Aggression von Ärzten in ihrem Bericht über die Durchführung präklinischer Wiederbelebungen erfaßt und mit den Werten einer Normalbevölkerungsstichprobe verglichen. Ärzte wiesen signifikant höhere Werte für Angst- und Aggressionssummenscores auf als die Vergleichsstichprobe. Einzelscores für Todes-, Trennungs- und Schamangst waren signifikant höher, für Verletzungsangst und diffuse Angst niedriger als in der Normalbevölkerung. Die Schuldangst unterschied sich nicht. Die Ergebnisse für offen nach außen gerichtete Aggressivität waren gleich, die für nach außen verdeckte und nach innen gerichtete Aggressivität waren signifikant höher als in der Normalbevölkerung. Bei der ambivalenten Aggressivität zeigte sich kein Unterschied. Scores der Ärzte für positive Hoffnung waren signifikant niedriger, diejenigen für negative Hoffnung unterschieden sich nicht von der Normalbevölkerung. Im Vergleich zur Normalbevölkerung ergaben sich insgesamt drei Hinweise auf Hindernisse für Ärzte, mit Angst, Hoffnung und Aggressivität in Reanimationssituationen angemessen umzugehen: Ärzte scheinen sich weniger mit Verletzungs-, diffuser- sowie Schuldangst auseinanderzusetzen. Der Umgang mit Aggressionen offenbart Mechanismen der Verdrängung, Projektion und Wendung gegen das Selbst. Gegenüber der Normalbevölkerung scheinen Ärzte nicht intensiver über die mit ihrer Tätigkeit verbundene Hoffnungslosigkeit zu sprechen.

    Notes: Zusammenfassung An Hand von 52 Aorten, die durch Unterbindung sämtlicher Äste abgedichtet werden konnten, wurde dasAorten-Fassungsvermögen von der Geburt an bis in das höhere Lebensalter bei verschiedenen Füllungsdrucken festgestellt undmit den Volumina des arteriellen Windkessels verglichen, die auf Grund kreislaufmechanischer Daten bei Lebenden errechnet werden können. Die zugleich direkt ermitteltenSpeichervolumina von Gesamtaorten erweisen sich etwa bis zum 50. Lebensjahr annähernd dem halben Herzschlagvolumen gleich. Die Gegenüberstellung derAorten-Volumendehnbarkeit verschiedener Altersstufen ergibt, daß diese im Verlauf des Lebens einer gesetzmäßigen Entwicklung unterworfen ist, in der diePhase der zunehmenden Dehnbarkeit (von der Geburt an bis zum Alter von 10–20 Jahren) und die darauffolgende Phase desfortschreitenden Dehnbarkeitsverlustes zu unterscheiden ist. — Die Aorten vonHypertonikern höherer Altersstufen (7. Lebensdekade) weisen ein wesentlichgrößeres Fassungsvermögen auf und sind zugleichetwas dehnbarer als die Aorten der Normotoniker. Die im höheren Alter oft verstärkt auftretendeherdförmige Arteriosklerose der Aorta setzt ihre Volumendehnbarkeit über den Altersdurchschnitt herab.Das stärkere Befallensein der Bauchaorta durch die herdförmigen sklerotischen Veränderungen wird vermutlich durch ihre von vornherein geringere Dehnbarkeit und einen etwas höheren altersgebundenen Dehnbarkeitsverlust mit begünstigt. Die Untersuchungder Druck-Längenbeziehungen der Aorta ergab, daß unter einem Füllungsdruck, der einer normalen intravasalen Druckbelastung entspricht,die Aorta im Körper nahezu spannungsfrei verankert ist.
