    Notes: [Auszug] Barbed bone points, typical of those from the early Holocene settlement of “Early Khartoum”, have been found at three sites along the White Nile, south of Khartoum. The form of the fragments and the stratigraphy of the sites throw light on the environment and technology of the early ...

    Notes: Abstract Experimental determinations of the local heat transfer by forced convection from model leaves heated by a constant energy flux were made in the laboratory under laminar and turbulent flow conditions. The results are expressed in a logarithmic dimensionless plot of the local Nusselt number, Nu d , against the local Reynolds number, Re d . For the laminar case, Nu d was only a linear function of Re d 1/2 downwind from the leading edge regions, although this relationship departed from that predicted theoretically due to the finite size and thickness of the model. For the turbulent case, a simple relationship between Nu d and Re d was found over a wide range of Reynolds numbers. The enhancement of heat transfer in the turbulent case depends primarily on the scale of turbulence rather than on the turbulent intensity. Past workers have discussed their results in relation to a factor β, defined as the ratio between the heat transfer predicted by the Polhausen equation, and that measured. The results suggest that β is not a unique parameter and may not be useful in describing the overall turbulent transfer process.

    Description / Table of Contents: Sommaire Un modèle de la fonction des terminaisons nerveuses sympathiques des tissue ventriculaires a été développé par analogie avec les différentes fonctions neuromusculaires et interneuronnaires. Le modèle caractérise la jonction neuromusculaire ventriculaire par deux sous-systèmes: un mécanisme de libération neurotransmettrice produit la concentration noradrenalineNE(t) selon un comportement global régulier imitant les données de Rosenbleuth (1932), et une réponse dynamique réalistique à la fréquence des stimulations multiplesf s. Dans cette étude, le principe de la contraction ventriculaire se base sur l'extension du modèle fonctionnel existant de la mécanique ventriculaire du coeur dépouillé de ses nerfs (Greene et al., 1973) à la considération de divers états d'intervention inotropique positive. En tout, cette étude a eu pour résultat la création d'un modèle de la mécanique ventriculaire qui reflète les changements d'état inotropique, de volume diastolique final et de durée.
    Abstract: Zusammenfassung Es wurde ein Modell der Funktion sympathischer Nervenenden im ventrikulären Gewebe durch Analogie mit verschiedenen endoneuralen und neuromuskulären Verbindungen entwickelt. Das Modell zeigt die ventrikuläre neuromuskuläre Verbindung anhand von zwei Systemgruppen—einem Auslösemechanismus für die Nerveübertragung und einem ventrikulären Kontraktionsmechanismus. Die Leistung des Auslösemechanismus der Übertragung ist die Noradrenalinkonzentration NE(t) in kompaktem Festkörperverhalten, die die Daten von Rosenbleuth (1932) und eine realistische dynamische Reaktion auf mehrfache Frequenzstimulif s nachahmt. In dieser Untersuchung basiert der ventrikuläre Kontraktionsmechanismus auf einer Erweiterung eines bestehenden Funktionsmodells der ventrikulären Mechanik eines Herzens mit ausgeschalteter Nervenzufuhr (Greene u.a., 1973) zur Berücksichtigung verschiedener Zustände inotroper Intervention. Insgesamt ergibt sich aus dieser Untersuchung das Modell einer ventrikulären Mechanik, die die Änderungen im inotropen Zustand, im enddiastolischen Volumen (Vorbelastung) und in der Zeit widerspiegelt.
    Notes: Abstract A mathematical model of the function of sympathetic neural terminations in ventricular tissue is developed by analogy with various interneural and neuromuscular juctions. The model characterises the ventricular neuromuscular junction in terms of two subsystems—a neurotransmitter release mechanism and a ventricular contraction mechanism. The output of the transmitter release mechanism is the noradrenaline concentrationNE(t) in a lumped steady-state behaviour that mimics the data of Rosenbleuth (1932) and a realistic dynamic response to multiple stimuli of frequencyf s. The ventricular contraction mechanism in this study is based on an extension of an existing functional model of ventricular mechanics for the denervated heart (Greeneet al., 1973) to a consideration of various states of positive inotropic intervention. Overall, this study results in a model of ventricular mechanics that reflects changes in inotropic state, end-diastolic volume (preload) and time.
