The area of study belongs to the higher building of the base of Small Kabylie. It consists of several tectono-lithological units affected by a metamorphism épizonale to mésozonale of low pressure and high temperature. This last estimated at P=4-5 Kbar and T=650-700°C is underlined by the presence of the veins of leucozones and the myrmékite thus near to the field of partial fusion. The structural draft shows the superposition of schisto-sandy units épizonales on units of higher rank. This area is overcome in its Western and Eastern part by formations of Oligo-Miocène-Kabyle. The study of the syn-schistous deformation highlights an extensive component at vergency is and of the linéations of stretching of direction E - W (D1) with a virgation towards the NNE. This deformation induces the shape in arc marked by plans of schistosity and foliation resulting from the deformation (D2) due to the accommodation of the total overlapping of the building of Beni-Ferguène towards the NW. Alpine and eo-alpine post-schistous deformations of lower (Pt), at vergency East and South, are highlighted.

Problems related to seepage through earth dams constitute more than 40% of the sources of observed damages throughout the world. A particular attention is given to how to minimize the effects due to seepage by using an adequate means of drainage to ensure the hydraulic and mechanical stabilities of the dam. In the homogeneous earth dams, the filtering drainage blanket is used with dimensions and location in the backfill determined by some unreliable methods. In this work a simple chart is developed in order to effectively locate the filtering drainage blanket along with a graph giving its length. This graph was obtained after having carried out a computer simulation of a great number of earth dams in which the total height, the embankment slopes, and the material characteristics were varied. For each dam, the drain length is changed within the acceptable limits of the hydraulic stability and the landslide stability of the downstream side embankment which is calculated.

Le travail que nous proposons a pour objet d’étude la publicité (illustrée par l’une de ces formes), cette publicité qui peut très bien être ce capital dont parle J. Demorgon. Il s’agit de lire à travers elle le culturel pour pouvoir prétendre à une possible communication interculturelle entre celui à qui appartient ce capital et auquel s’adresse cette publicité et celui qui, de l’extérieur, entreprend cet autre regard possible.
