Available in PDF, EPUB and Kindle. Book excerpt: A partir de la répartition des polluants sur la région suivant ce cadastre, les données obtenues ont servi de données d'entrées pour un modèle de simulation physicochimique de la troposphère (UAM Urban Airshed Model). Une étude précédemment menée, portant sur l'introduction de la spéciation moléculaire détaillée des COV et l'utilisation du mécanisme CBIV n'a pas donné de résultats concluants quant à l'impact de cette spéciation sur la formation d'ozone. Nous souhaitions par l'introduction d'un nouveau mécanisme avoir une prise en compte meilleure de l'ensemble de ces composés et voir ainsi leur contribution éventuelle sur la formation d'ozone sur notre domaine. Ceci nécessitait une adaptation du modèle et notamment l'installation d'un module (interface FCM = Flexible Chemical Mecanism) permettant l'introduction d'un nouveau mécanisme chimique (SAPRC 99 au lieu du CBIV) au sein même du modèle. L'ensemble des fichiers d'entrées a été adapté pour la prise en compte de la totalité des composants. L'influence de la spéciation des COV sur la formation d'ozone sur un épisode de simulation a été ensuite étudiée avec une augmentation de la concentration d'ozone calculée aux stations et un pourcentage moyen d'écart sur la formation d'ozone de l'ordre de 28% par rapport aux calculs avec le précédent mécanisme.

This book was released on 2002 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: La connaissance des émissions automobiles de polluants réglementés (CO, HC, NOx et particules) est de nos jours bien développée. Cependant, le manque de données concernant les polluants non réglementés comme les Composés Organiques Volatils (COV) nécessite d'être comblé pour mieux appréhender les problèmes de pollution de l'air liés aux transports routiers. Ainsi, l'objectif de ces travaux était d'identifier et de quantifier individuellement les COV, particulièrement les hydrocarbures de C2 à C14 et les dérivés carbonylés, à l'émission de véhicules particuliers placés en conditions réelles de conduite. Un échantillon de 25 véhicules particuliers a été sélectionné sur la base d'une prévision de la constitution du parc automobile français de 2001. Divers types de technologies, i.e. véhicules essence et diesel équipés ou non de catalyseur, ont été testés sur banc à rouleau avec échantillonnage à volume constant (CVS) pour déterminer les émissions réglementées et les COV individuels. Les facteurs d'émission (g/km) moteur chaud d'une centaine de polluants ont été établis suivant quatre cycles de conduite modem Hyzem pour retracer les comportements de conduite réels urbains, routiers et autoroutiers. De plus, un intérêt particulier a été porté aux composés toxiques et/ou photochimiquement réactifs comme le benzène, le formaldéhyde, l'acétaldéhyde et le 1,3-butadiène. Ainsi, une évaluation de la toxicité et du potentiel de formation d'ozone a été menée afin de comparer l'impact respectif des émissions des motorisations testées. Finalement, ces résultats ont été appliqués à un inventaire d'émissions afin d'évaluer l'impact de la modification de la spéciation des COV automobiles sur les sorties d'un modèle eulérien 3D de chimie/transport (Urban Airshed Model IV).

Available in PDF, EPUB and Kindle. Book excerpt: In the preface to Volume 1 of the 'Annals of Life Insurance Medicine' Dr. MAX E. EISENRING described the goal of this publication as follows: "Any project which aims at contributing substantially to the modern science of medical underwriting can do so only if the many people preoccupied with these problems throughout the world join forces to the ultimate benefit of those most in need of life assurance." In an endeavour to keep the life insurance medical directors all over the world informed of the developments in the field of life insurance medicine, we have decided to publish the papers which were presented at the 11 th International Congress of Life Assurance Medicine in Mexico in 1973 in Volume 5 of the 'Annals'. We are most grateful to Dr. J. REN06N, President of the Organizing Commit tee of the Congress in Mexico for having consented to our publishing the proceed ings of the Congress in a special edition of the 'Annals'. It is a source of great satisfaction to us that in this way a much larger circle of life insurance medical directors can be reached than would have been the case if only the participants themselves were to receive the proceedings of the Congress. Dissemination of the results of medical research on an international basis, in particular those findings that have a bearing on life insurance medicine, is one of our foremost aims.

Available in PDF, EPUB and Kindle. Book excerpt: This book is developed from and includes the presentations of leading international experts and scholars in the 12-14 July, 2006 Wingspread Workshop. With urban waters as a focal point, this book will explore the links between urban water quality and hydrology, and the broader concepts of green cities and smart growth. It also addresses legal and social barriers to urban ecological sustainability and proposes practical ways to overcome those barriers. Cities of the Future features chapters containing visionary concepts on how to ensure that cities and their water resources become ecologically sustainable and are able to provide clean water for all beneficial uses. The book links North American and Worldwide experience and approaches. The book is primarily a professional reference aimed at a wide interdisciplinary audience, including universities, consultants, environmental advocacy groups and legal environmental professionals.
