Book Description
Depuis les origines, le film a été le média privilégié de l'imagerie X. Simple à utiliser et ne nécessitant aucune infrastructure mis à part la source de rayons X, il a permis la généralisation voire la banalisation du contrôle non destructif. Dans les dernières décennies, le film a commencé à partager son hégémonie avec à la fluoroscopie dans des applications où l'accent est mis sur la rapidité d'accès à l'image radiologique. Plus récemment, la fluoroscopie est elle même en train d'être remplacée par des dispositifs intégrés, à base de semi-conducteurs. Ces nouveaux imageurs, plus compacts, fournissent directement une version numérique de l'image. Les capteurs linéaires (ou barrettes) se prêtent particulièrement bien au Contrôle Non Destructif (CND) en temps réel sur des produits en défilement. Néanmoins, bien que prometteuses, ces nouvelles techniques se heurtent le plus souvent à un manque de résolution. Notre travail est une contribution à l'amélioration de la résolution des détecteurs à l'état solide sensibles aux rayons X. Cette contribution s'applique tout particulièrement au domaine du temps réel. Notre approche comporte trois axes principaux. Une première contribution concernant la modélisation de la dégradation, où une nouvelle technique a été mise au point. Un deuxième axe a consisté en la mise en oeuvre de certaines méthodes de restauration. L'accent a été mis sur l'aspect temps réel, nous avons étudié certaines configurations géométriques particulières pouvant donner des résultats intéressants lors de la restauration des signaux. Un dernier axe de recherche exploratoire a été mené dans le sens de l'optimisation des paramètres intrinsèques au capteur grâce à une simulation comportementale.

Book Description
In a time of rapid climatic, industrial and technological changes in molluscan shellfish producing and exporting regions, it is of the utmost importance to keep a keen eye on developing trends. This collection of recent research in molluscan shellfish safety, risk assessment, risk management, regulation and analytical methods presented at the 8th ICMSS (International Conference on Molluscan Shellfish Safety) offers valuable insights in the latest scientific findings. Dans le contexte actuel de changements climatiques, industriels et technologiques rapides dans les régions qui produisent et qui exportent des mollusques, il est essentiel de rester à l’affût des nouvelles tendances. Ce recueil des récents travaux de recherche dans les domaines de la salubrité des mollusques, des évaluations des risques, de la gestion des risques, de la réglementation et des méthodes d’analyse présentés lors de la 8e Conférence internationale sur la salubrité des coquillages (ICMSS) vous aidera à le faire.

Book Description
The matrix isolation (MI) method has now been used for nearly thirty years. During this period it has been actively developed and the range of problems tackled greatly extended. Originally it was used for studies of transient species involv ing vibrational, electronic and ESR spectroscopy. Nowadays the study of transient species forms a comparatively small part of HI work since it has been amply demonstrated that very fruitful information can be obtained of the structure and interactions of stable molecules and their aggregates. In addition to the s~ectroscopic methods mentioned above the MI technique is nowadays a standard method in research based on vibrational relaxation, luminescence, Mossbauer, magnetic circular dichroism, pulsed NMR and photoelectron spectroscopy. The matrix isolation technique affords considerable advantages over more conventional methods in most applications of spectroscopy. Areas where the technique has been widely applied, or shows great potential, include: metal atom chemistry, and its relation to surface chemistry, high temperature inorganic species, transition metal complexes, interstellar species, free radicals and unstable molecules, conformational studies, molecular com plexes, and intermolecular forces.

Book Description
The Cambridge Yearbook of European Legal Studies provides a forum for the scrutiny of significant issues in EU Law, the law of the European Convention on Human Rights, and Comparative Law with a 'European' dimension, and particularly those issues which have come to the fore during the year preceding publication. The contributions appearing in the collection are commissioned by the Centre for European Legal Studies (CELS) Cambridge, a research centre in the Law Faculty of the University of Cambridge specialising in European legal issues. The papers presented are at the cutting edge of the fields which they address, and reflect the views of recognised experts drawn from the University world, legal practice, and the institutions of both the EU and its Member States. Inclusion of the comparative dimension brings a fresh perspective to the study of European law, and highlights the effects of globalisation of the law more generally, and the resulting cross fertilisation of norms and ideas that has occurred among previously sovereign and separate legal orders. The Cambridge Yearbook of European Legal Studies is an invaluable resource for those wishing to keep pace with legal developments in the fast moving world of European integration.

Book Description
This book highlights that Soviet economic planners and politicians must come to recognize the need to make fundamental changes, not simply incremental refinements, in the failing Soviet system. It examines the dynamics of the process of perestroika and the complexity of individual economic issues.
