Benefiting from exceptional credits voted in 1833, the Muséum national d’Hstoire naturelle de Paris had the opportunity to modernize the garden that houses it and was one with it: the Jardin des Plantes. The young architect Charles Rohault de Fleury (1801-1875), appointed a year earlier chief architect of the Museum, thus inherited the responsibility of designing new buildings and decorations that reflect the scientific ambition attached to this place: to preserve and exhibit all the natural productions of the globe.

Les propriétés germicides des rayonnements ultraviolets (UV) suscitent un intérêt de plus en plus important dans les domaines d'applications stratégiques que sont l'environnement et la santé. Les diodes électroluminescentes (LEDs) semi-conductrices à base de nitrure d'aluminium et de gallium représentent les nouvelles sources d'émission UV qui pourront répondre à cette demande. Leurs performances, bien qu'encore modestes, progressent chaque jour et nous vivons le point de bascule entre le laboratoire et le domaine grand public. Pour définitivement parvenir à s'imposer, elles doivent associer efficacité, forte capacité de développement, ainsi que souplesse et facilité d'utilisation, performances qu'aucune source UV n'a encore atteint jusqu'à présent.

The article presents a study which focuses on the French international company offering services in project management, engineering, and construction for the energy industry Technip, which was founded by the French government in 1958 and specialized in petroleum engineering. It analyzes the structural changes in the economies of developed countries since 1958 and the history of the company with focus given to three periods including 1958 to 1974, 1974 to 1994, and 1994 to 2012. France's petroleum policy during the 1950s, the role of technology in the company's growth, and Technip's development into an international company are discussed.
