Résumé : Ocean Thermal Energy Conversion, OTEC, is a concentrated renewable source of energy available in the one third of the world's ocean lying in the tropics. An OTEC plant is a heat engine fed with warm surface water and cold water pumped up from the deep. The difference of temperature, 20°C, is small, it can be used to produce electricity as well as fresh water. Plants can be installed on land or at sea. The main problem is to build and deploy a large diameter pipe to pump the cold water from 600 to 1 000 m in depth. France, who discovered the idea realised some major demonstrations fifty years ago. More recently US and Japanese firms have spent more than dollars 200 millions to develop prototypes and research in this field. Several major OTEC pilot plants are presently discussed mainly hy US, Japanese and French teams. The main challenge is to prove the potential competitivness of OTEC electricity in the 10 to 100 MWe range, with diesel electricity in the 1990's. Production of OTEC desalination water and marine proteins are also under consideration. The present book give a unique overview of both technical and economical aspects of this promising source of energy. [NOT CONTROLLED OCR]
L'Océan présente un potentiel considérable d'énergie renouvelable. Dans ce domaine, l'énergie thermique des mers (ETM) apparaît très riche de promesses. C'est une idée française: elle est due à d'Arsonval (1881). Les travaux de G. Claude et P. Boucherat (1928-1934), les projets d'Abidjan (1940-1956) et de la Guadeloupe (1958) essaieront de la matérialiser. Depuis les années 60, ce sont surtout les Américains et les Japonais qui développent les recherches. La France a repris ses projets à partir de 1978, de même que certains pays d'Europe, Cet ouvrage expose les caractéristiques de l'ETM et fixe les ordres de grandeur qui permettent de dimensionner les composants d'une centrale. Il rend compte des recherches menées dans différents pays pour maîtriser la technologie ETM :aux États-Unis, au Japon, en Grande-Bretagne, en Suède, en France et, plus récemment, en Inde ou à Taïwan. Il examine les potentialités réelles dans 98 pays et territoires qui ont accès au gisement ETM et dont les 2/3 sont dans la mouvance européenne. L'étude traite enfin du coût de cette énergie dans la perspective d'une compétitivité du KWG/ETM avec le KWG/fioul. L'examen porte ainsi sur d'autres actions possibles: production eau douce, aquaculture, froid. [OCR NON CONTRÔLE]

Résumé : International audience
To investigate the contribution of whole-body post-mortem computed tomography (PMCT) in sudden unexpected death in infants and children.METHODS:Forty-seven cases of sudden unexpected death in children investigated with radiographic skeletal survey, whole-body PMCT and autopsy were enrolled. For imaging interpretation, non-specific post-mortem modifications and abnormal findings related to the presumed cause of death were considered separately. All findings were correlated with autopsy findings.RESULTS:There were 31 boys and 16 girls. Of these, 44 children (93.6 %) were younger than 2 years. The cause of death was found at autopsy in 18 cases (38.3 %), with 4 confirmed as child abuse, 12 as infectious diseases, 1 as metabolic disease and 1 as bowel volvulus. PMCT results were in accordance with autopsy in all but three of these 18 cases. Death remains unexplained in 29 cases (61.7 %) and was correlated with no abnormal findings on PMCT in 27 cases. Major discrepancies between PMCT and autopsy findings concerned pulmonary analysis.CONCLUSIONS:Whole-body PMCT may detect relevant findings that can help to explain sudden unexpected death and is essential for detecting non-accidental injuries. We found broad concordance between autopsy and PMCT, except in a few cases of pneumonia. It is a non-invasive technique acceptable to relatives.KEY POINTS:• Whole-body post-mortem computed tomography (PMCT) is an effective non-invasive method. • Whole-body PMCT is essential for detecting child abuse in unexpected death. • There is concordance on cause of death between PMCT and autopsy. • Whole-body PMCT could improve autopsy through dissection and sampling guidance. • PMCT shows findings that may be relevant when parents reject autopsy.

Résumé : International audience
Idiopathic pulmonary fibrosis (IPF) is the most frequent chronic idiopathic interstitial pneumonia in adults. The management of rare diseases in France has been organised by a national plan for rare diseases, which endorsed a network of expert centres for rare diseases throughout France. This article is an overview of the executive summary of the French guidelines for the management of IPF, an initiative that emanated from the French National Reference Centre and the Network of Regional Competence Centres for Rare Lung Diseases. This review aims at providing pulmonologists with a document that: 1) combines the current available evidence; 2) reviews practical modalities of diagnosis and management of IPF; and 3) is adapted to everyday medical practice. The French practical guidelines result from the combined efforts of a coordination committee, a writing committee and a multidisciplinary review panel, following recommendations from the Haute Autorité de Santé. All recommendations included in this article received at least 90% agreement by the reviewing panel. Herein, we summarise the main conclusions and practical recommendations of the French guidelines.
