States of the situations of energy, water and solar distillation in the world have been dressed. From this, two new solar still models have been developed, one theoretically: flowing solution over inclined flat plates solar still; and the other experimentally: canals solar still. To study the effect of significant parameters on the evaporated volume water of a flowing solution on a heated inclined plate or several inclined plates solar still, a mathematical two dimensional flow analysis was carried out based on continuity, momentum and energy equations for the liquid phase. It is shown that the significant parameters are the film thickness, the plate length and inclination, and the heat at the wall which represents the solar radiation absorbed by the plate. In the experimental studies, canals solar still prototype of 0, 6 m2 in area has been designed and tested. The tests have shown the effects of certain atmospheric, design and operational techniques parameters on the output and the operation of the solar still. It has been concluded that the solar radiation, the solar movement pursuit, the distance covered by the solution and a good thermal isolation, have a significant effects on the output of the solar still whose distilled water production has reached an appreciable quantity of 2,7 l (i.e. 4,8 l/m2). Finally, some propositions have been suggested for further study, to develop the two new types of solar stills.

Have proceeded many of the Algerian universities to adopt this type of education for the development of education and to achieve greater efficiency and quality of the output of the educational process. And the University of Skikda, like other Algerian universities have developed a cell of the e-learning which is based on the establishment of a platform for elearning and the formation of both teachers and students to move to this new style of education. The aim of this study was to investigate a broader e-learning by the University of Skikda and the extent of its application by knowing the ingredients and preparations created by the University of Skikda to implement the project in addition to detection of the various problems and obstacles that limit the use or application by the elements of the educational process.
