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.

Gas turbines are of prime importance to aircrafts. The turbo machinery is a complex aspect of designing. Efficiency of turbo machinery is closely proportional to material selection and its performance. Each section of a turbo machinery deserves or has a different criteria of temperature dependency. As per this dependency turbine blades, nozzles and wheels are designed using different types of materials- alloys, which are highly resistant to temperature and light weight. This will lead to aircrafts which are very light and highly efficient. These materials are alloys which are very costly. And this high cost are making them difficult to be used abundantly. All these problems has made researchers to look around for material which is light, comparatively cheap and highly efficient as per turbine needs. This paper throws light on the existing materials used in turbine blades and a new compound which is a carbon allotrope which is capable of meeting all above needs perfectly.
