Book Description
CALCUL DU SPECTRE D'ABSORPTION PAR COMPARAISON DES INTENSITES EMISES SELON L'AXE DE DEUX PLASMAS DE FORME CYLINDRIQUE, NE DIFFERANT QUE PAR LEUR LONGUEUR. DANS L'ION LITHIMOIDE D'AL (AL**(10+)) LES CARACTERISTIQUES D'ABSORPTION POUR PLUSIEURS TRANSITIONS CONDUISENT A CONCLURE A UN FORT DESEQUILIBRE DANS LA POPULATION DE CERTAINS NIVEAUX. ON ETUDIE L'INVERSION DE POPULATIONS ENTRE LES NIVEAUX 5F ET 3D, OBSERVEE DANS AL**(10+) MAIS AUSSI MG**(9+). POUR AL**(10+), ON MONTRE COMMENT CETTE INVERSION EST INFLUENCEE PAR LA VARIATION DES PARAMETRES DE PRODUCTION DU PLASMA. L'ETUDE PERMET DE CERNER LES CONDITIONS DANS LESQUELLES CETTE INVERSION PEUT CONDUIRE A UNE AMPLIFICATION DU RAYONNEMENT X-UV.

Book Description
The Encyclopedia of Sustainability Science and Technology (ESST) addresses the grand challenge for science and engineering today. It provides unprecedented, peer-reviewed coverage in more than 550 separate entries comprising 38 topical sections. ESST establishes a foundation for the many sustainability and policy evaluations being performed in institutions worldwide. An indispensable resource for scientists and engineers in developing new technologies and for applying existing technologies to sustainability, the Encyclopedia of Sustainability Science and Technology is presented at the university and professional level needed for scientists, engineers, and their students to support real progress in sustainability science and technology. Although the emphasis is on science and technology rather than policy, the Encyclopedia of Sustainability Science and Technology is also a comprehensive and authoritative resource for policy makers who want to understand the scope of research and development and how these bottom-up innovations map on to the sustainability challenge.

Book Description
Advances in the synthesis of new materials with often complex, nano-scaled structures require increasingly sophisticated experimental techniques that can probe the electronic states, the atomic magnetic moments and the magnetic microstructures responsible for the properties of these materials. At the same time, progress in synchrotron radiation techniques has ensured that these light sources remain a key tool of investigation, e.g. synchrotron radiation sources of the third generation are able to support magnetic imaging on a sub-micrometer scale. With the Fifth Mittelwihr School on Magnetism and Synchrotron Radiation the tradition of teaching the state-of-the-art on modern research developments continues and is expressed through the present set of extensive lectures provided in this volume. While primarily aimed at postgraduate students and newcomers to the field, this volume will also benefit researchers and lecturers actively working in the field.
