    L’Observation du Comportement du Nouveau-Ne: Une Source Pertinente d’Informations Medicales

    L’observation du comportement du nouveau-né est une source importante d’informations d’ordre médical. Trois domaines bénéficient des données de l’observation : 1) l’analyse du développement grâce à l’utilisation de l’Assessment of Preterm Infant Behavior (évaluation du comportement de l’enfant prématuré) ; 2) l’évaluation de la douleur dominée par l’analyse de l’expression faciale grâce à des échelles validées, telle que le Neonatal Facial Coding System (système néonatal de codage facial) ; 3) la recherche de lésions cérébrales par le Quality Assessment of General Movements (évaluation de la qualité des mouvements généraux). L’observation comportementale fondée sur des outils validés par la recherche clinique constitue un complément utile des données de l’imagerie en période néonatale. The neonatal behavioral observation is an important source of medical informations in three domains: 1) assessment of development which can be done with the Assessment of Preterm Infant Behavior, 2) assessment of pain with the analysis of facial expression using validated pain scales such as the Neonatal Facial Coding System, 3) assessement of brain injuries with the Quality Assessment of General Movements. Such a behavioral observation of the newborn using validated tools is a useful complement of the neuro-imaging techniques

    Neutron-induced nucleosynthesis

    Neutron--induced nucleosynthesis plays an important role in astrophysical scenarios like in primordial nucleosynthesis in the early universe, in the s--process occurring in Red Giants, and in the α\alpha--rich freeze--out and r--process taking place in supernovae of type II. A review of the three important aspects of neutron--induced nucleosynthesis is given: astrophysical background, experimental methods and theoretical models for determining reaction cross sections and reaction rates at thermonuclear energies. Three specific examples of neutron capture at thermal and thermonuclear energies are discussed in some detail.Comment: 40 pages (uses kluwer.sty), 2 postscript figures (uses psfig), accepted for publication in Surveys in Geophysics, uuencoded tex-files and postscript-files available at ftp://is1.kph.tuwien.ac.at/pub/ohu/Geo.u
