Using a system of cavity quantum electrodynamics （QED） we present two schemes for multipartite entan- glement generation. In the first scheme, a three-level atom is interacting with three cavities successively. In the second one, two three-level atoms are interacted with a coherent optical cavity. These protocols allow us to generate the six c/asses of tripartite entanglement （GHZ, W, A-B-C, AB-C, C-AB, and B-AC class states） by controling the interaction time between atoms and cavities. Moreover, they allow us to generate entanglement between the cavity fields degrees of freedom （from the first scheme）, and a mixed entanglement between the cavity field degrees of freedom and the atomic degrees of freedom.

Polypropylene （PP） matrix composites reinforced with chemically treated Almond Shell （AS） particles with and without compatibilizer （PP-g-MA） was prepared by a twin-screw extrusion at loading of 20 wt.% AS particles. Two types of chemical treatments （alkali treatment with sodium hydroxide and etherification with dodecane bromide） of the particles were carried out to improve the interface adhesion between particles and PP matrix. Results show that chemical modifications of AS particles affect the mechanical and viscoelastic properties of AS/PP composites. The composites reinforced with alkali treated particles and the compatibilized matrix lead to a notable increase in the Young＇s modulus （14%） compared to the composites with untreated AS particles. The ductility of composite was also evaluated by the yield strain, and results show a notable increase （31%） compared to that of composites with untreated particles. The thermal stability increased with the use of etherification （385 ℃）, with gains in the temperature up to 23 ℃ compared to neat PP （362 ℃）. The achieved results show that the AS/PP composites can be used in several applications. A thermoplastic matrix compsite mixed with treated AS particles appears to be a good alternative to obtain environmentally friendly products.

The low recharge of reservoirs and the increasing demand for water limit the potential of mobilized resources, especially in arid to semi-arid areas like Morocco. Integrated management is essential to safeguard this resource. In respect with this perspective, this work provides the analysis of hydrogeological potential of Khemisset-Tiflet region, which falls within the action area of the Sebou Hydraulic Basin Agency. The basis of our studies was as follows:(1) The interpretation of the existing geoelectric data;(2) application of geophysical methods for non-destructive reconnaissance and their integration into a Geographic Information System(GIS). The analysis demonstrates that: The map of the isohypses and the geoelectric cross-section of the substratum of the superficial roof aquifer show clearly a plunge associated with development of the Paleozoic roof in the South and the direction of flow of the surface water is from south to north, from the upper zone to the north of the El Kansera dam. These conclusions constitute very useful contribution for any resource management projects in this area.
