Two experiments on the generation of internal waves in a two-layer fluid are considered. In the first experimental configuration, it is shown that when a periodic current flows along a coast and past a cape, dispersive waves are generated to the right of the cape (facing onshore), and trains of rank-ordered solitary Kelvin waves are periodically shed along the wall, to the left of the cape. Moreover, there is a mean current generated in both layers, parallel to the Barbour Bedale Pas Cher wall, to the left of the cape in the lower layer and to the right of the cape in the upper layer. In the second configuration, it is demonstrated that when a periodic current flows over an obstacle, when the rotation is strong, only dispersive waves can be observed far from the obstacle, whereas when the notation is weak, trains of solitary waves can be observed far from it. The hydraulic conditions over the obstacle affect only the wave amplitude.

Prolonged controlled release of drugs from polymeric matrices is now well established. In contrast, however, release of macromolecules presents more difficulties and in consequence is less well studied and relatively rarely discussed in the literature. The processes of biodegradation and bioerosion which are important in this field have been Barbour France Magasins exploited in other types of surgical device for some years. This review brings Barbour Vetements De Chasse together the literature on various aspects of the bioerosion of polymers containing ester groups, with particular emphasis on release and degradation studies that might form a basis for the design and selection of controlled macromolecular release systems. Polymers discussed include the poly(alpha esters) -including poly(lactic acid) and polyfglycolic acid) —, poly(3-hydroxybutyrate), polydioxanes, polyoxalates, polylactones, polyester hydrogels and the polyanhydride/poly(ortho ester) series.
