    Description / Table of Contents: Abstract Les auteurs étudient les aspects morphologiques et structuraux du carrefour hépatico-cave. Cette étude porte sur 20 sujets adultes des deux sexes après formolisation. Les veines hépatiques et leurs terminaisons dans la veine cave inférieure sont prélevées, étudiées sur le plan macroscopique et incluses dans la paraffine. Les coupes sériées sont fixées selon la technique d'Azan. Trois veines hépatiques sont retrouvées dans tous les cas : les veines hépatiques droite, moyenne et gauche. Dans 20% des cas, la veine moyenne s'ouvre directement dans la veine cave inférieure. L'ostium des veines hépatiques s'appuie sur deux piliers réunis à leur partie inférieure par un repli semilunaire. La paroi des veines hépatiques au niveau de leur ostium est très épaisse avec un fort contingent de fibres musculaires et collagènes. Les fibres musculaires réalisent un véritable sphincter qui peut jouer un rôle physiologique dans le contrôle de la circulation hépatique.
    Notes: Summary The authors studied the morphological and structural aspects of the junctions between the hepatic veins and the inferior vena cava. The study was carried out on 20 specimens obtained from adult cadavers of both sexes, fixed in 10% formaldehyde solution. The hepatic veins with their junctions on the inferior vena cava were isolated. Then a macroscopic analysis of the openings of the hepatic veins into the inferior vena cava was performed. Part of this material was embedded in paraffin, submitted to serial sectioning and stained with Azan's trichrome and resorcin-fuchsin. Three hepatic veins were observed in all cases: right, left and the middle. In 20% of the cases the middle hepatic vein opens directly into the inferior vena cava. The hepatic vein openings are supported by two pillars inferiorly united through a semilunar fold. The hepatic vein wall is greatly thickened at the level of its junction with the inferior vena cava, showing a large ammont of muscular and collagenous fibers. These bundles constitute a sphincter-like formation which may play a physiological role in the control of the hepatic circulation.

    Notes: The electronic properties of a one-dimensional diatomic crystal have been analyzed by using the MO-LCAO method in the tight binding approximation, with mathematical techniques involved in setting up and solving difference equations. The approach gives the exact sets of analytic solutions for both localized and nonlocalized states. The theory of surface states is developed as a characteristic value problem. To illustrate the method the surface states for a semiinfinite crystal which contains a local imperfection at the surface were examined. It appears that this method has advantages over previous methods developed to solve surface problems in crystalline lattices.
