has always risen to challenges and overcome those imposed by its growth and development. The efficient management of production during the difficult times of the nationalization of hydrocarbons, the development and exploitation of a world scale gas chain, optimizing the opening of the national mining domain to partnership, and expanding internationally are among the most striking evidence. Sonatrach’s commitment to ethics is the fruit of this long history. We have the ardent duty to keep it

principle of gaseous diffusion. Following this process, Ernest O. Lawrence (inventor of the Cyclotron) at the University of California in Berkeley implemented a process involving magnetic separation of the two isotopes. Following the first two processes, a gas centrifuge was used to further separate the lighter U-235 from the heavier non-fissionable U-238 by their mass. Once all of these procedures had been completed, all that needed to be done was to put to the test the entire concept behind atomic fission

only 15-20 percent margin (Agnese, 2003). Mass customization Not only are supermarkets being forced to expand the types of products they offer, but they also have to cater to varied consumer tastes within categories. The increased demand for ethnic, natural and ready-to-eat lines is expanding quickly (Table II). A recent study by Williard Bishop Consulting found that in the year 2000, US sales of ethnic foods generated $50 billion in revenue. This number is expected to increase to $75 billion by 2008

d'interdire les HFC mais elle table plutôt pour l'instant sur une incitation à l'installation de solutions alternatives, car elle juge que les nouvelles technologies sont suffisamment développées pour être mises sur le marché [20]. /& 5 Que ce soit la F-Gas ou les réglementations plus strictes qui émergent dans certains pays, on sent bien que des mesures plus contraignantes concernant les HFC vont apparaître dans les années à venir. Ceci prouve l'urgence de développer des systèmes performants capables

triangle or other geometrical concepts ; they only know circles. No notion of figures above 5, and even under 5 they count with the vague notions of "few" and "a lot". No notion of direction (N, S, E; W).

Fluid Cotton Filter Separatory Funnel Pyrex Dish and Stove Day 1: Day 2: Day 60: Day 61: Ingrediants were cut with scissors and places in coffee grinder for pulverizing. The contents were then placed in pyrex dish with cover. Dish was placed on gas stove and allowed to boil. After boil was achieved the stove was turned off. Periodically the stove was turned on to apply heat to the dish. After 20 minutes the biomass was strained. Placed biomass back into the dish and repeated twice.. Added Ronsonal

XIX th century. In the case of service network industries, public intervention was imposed when reality abundantly revealed the deficiencies of the market. Thus in the inter-war and post-Second-World-War periods, public organization of networks into natural monopolies was put in place within national frameworks, each according to its culture and the principles forged by economic theory (Allais, Boiteux...).
