The present work with economic importance concerns the diet of nine species of locust in the natural conditions in the Moroccan Middle Atlas. The dominant botanical species in each of the studied stations were also determined. This study allows understanding better the phenomena of competition and multitude. In the nature, these informs if a member of the Acrididae attacks the adventitious plants either the cultures. So, we used the method of the examination of the contents of the feces which consists in comparing the fragments of epidermic plants ingested by the locust with those of a reference collection prepared from existing botanical species in biotope. The determination of the diet, by the microscopic analysis of the contents of feces is the most objective by contribution in the direct observations on the ground. Besides this method does not perturb the demographic balance of the populations. The analysis of the food specter of nine species of Acrididaes shows that most part of locusts is polyphages to graminivorestendency, with the exception of Dociostaurusgenei who is oligophage. Acrididaespecie thus shows itself able of changing and of adapting its diet according to the availability of vegetables in its biotope. KEYWORDS: Acrididaes, Middle Atlas, fooddiet, vegetables, adaptation.

In 2001 Euroavia Toulouse organized a symposium on ground effect. We invited most of the Russian and German actors, and some experts from Holland, UK or France for a week of science around the subject of ekranoplans / flying boats. This was dedicated to students. A book was issued... and now that all copies have been sold for a while I am sharing this on LinkedIn for everyone. Enjoy. Stéphan AUBIN

Aircrafts involve the use of complex and advanced engineering devices, making them bulky and excessive fuel consuming mobility machines. The challenges today in the aviation industry is to reduce as much weight as possible; as every single pound of weight reduction directly affects fuel consumption and cost effectiveness.

Circulation control technology and motion in close proximity to the ground have both shown aerodynamic benefits in the generation of lift. Recent research efforts at West Virginia University have explored the potential of merging the two phenomena, in an attempt to enhance both technologies. This paper initiates this combined effort by experimentally investigating the impact ground effect has on the separation location of a jet blown tangentially over circulation controlled cylindrical surfaces. Previous experimental research on circulation controlled cylinders found an optimal radius of curvature and volumetric flow rate; whose model and optimal findings are built upon by this work through the addition of ground effect analysis by varying the ground height. The experiment investigates some of the variables that individually influence circulation control and ground effect; the variables are the radius of curvature, velocity of the jet, and the height from the ground. Data analysis revealed that for a constant volumetric flow rate and varying the height to radius (h/r) value, there is a large amount of variability in the data, indicating that the proximity of the ground has significant impact on the separation location and consequently influence on the potential lift characteristics. Furthermore, when this flow rate was analyzed, it was found that at an h/r of approximately 4.8, it appears that an optimal h/r occurs, based on the surface pressure and flow separation from the cylinders when not influenced by the ground. The data also found that at both radii, 0.520 and 0.659 inches, showed benefit when tested in close proximity to the ground. The findings demonstrate that there is further enhancement potential of the lift generating capability by uniting the lift enhancement of circulation control methodology with the ground effect flight regime. This effort is a preliminary study of a larger effort to determine if merging the two phenomena indicates a lift enhancement. This model does not have a free stream velocity, and subsequently does not measure lift, however, the findings depicted in this effort indicate that there is potential for enhancement, which is currently being researched by the authors.

Traction Citroën de la 7 à la 22 La Traction est présentée aux concessionnaires au mois de mars 1934 et fait son apparition dans les magasins d'exposition dès le mois suivant. Elle plaît d'emblée au public, grâce à l'excellente habitabilité que permet son absence de châssis, pour un prix qui reste raisonnable. La 7A, première version de la Traction, laisse place rapidement à la 7B, puis à la 7C qui adopte un moteur 1 628 cm3 développant 36 ch, tout en remédiant à plusieurs défauts de jeunesse. de 7S à 11 A à partir de novembre 1934, plus longues d'environ 20 cm et à la caisse plus large, moteur 4 cylindres 11 CV inauguré sur la 7S La 15-6 pour moteur 6 cylindres de 2 867 cm³ et 77 ch introduit en 1938 La 22 à moteur V8 de 3 822 cm³.une vingtaine d'exemplaires de présérie ont été fabriqués et certains vendus à une clientèle, aucune survivante en l'état
