Book Description
Nos activités ont porté à la fois sur le développement de moyens d'observations et sur la mise au point de nouvelles méthodes de restitution des propriétés des nuages et des aérosols, leur validation et l'analyse géophysique des produits dérivés pour application à la modélisation. Ces recherches mettent en œuvre principalement des observations depuis l'espace et visent, à travers la description à l'échelle globale des propriétés des nuages et des aérosols, à comprendre les processus qui gouvernent leur évolution. Dans un premier temps, les résultats obtenus ont principalement permis de mieux déterminer l'un des paramètres clés pour l'évolution d'un nuage et son impact radiatif : la phase thermodynamique de l'eau condensée. Par la suite, en cherchant à mieux comprendre les paramètres déterminant la phase du nuage, nous avons tenté d'établir les liens entre phase thermodynamique, propriétés microphysiques et conditions thermodynamique. Dans le même temps, les problématiques d'observation des nuages nous ont amené à nous pencher sur des questions plus générales de l'observation de l'atmosphère par télédétection concernant les aérosols et, de manière plus prospective, la vapeur d'eau. L'ensemble de ces travaux nous a conduit à proposer récemment un nouveau concept pour l'observation des nuages, des aérosols et de la vapeur d'eau depuis l'espace. Ce projet a été déposé auprès de l'Agence Spatiale Européenne (ESA) en réponse à son appel à idée pour la 8ème mission Earth Explorer. En remettant en perspective les travaux réalisés depuis dix ans, et concrétisés notamment au travers du projet récemment soumis à l'ESA, mais également en replaçant notre activité de recherche dans son contexte social, politique et économique, nous posons la question suivante sans avoir la prétention d'y répondre : "Qui se soucie vraiment des nuages, des aérosols et du climat ?"

Book Description
AEROSOL SCIENCE TECHNOLOGY AND APPLICATIONS Aerosols influence many areas of our daily life. They are at the core of environmental problems such as global warming, photochemical smog and poor air quality. They can also have diverse effects on human health, where exposure occurs in both outdoor and indoor environments. However, aerosols can have beneficial effects too; the delivery of drugs to the lungs, the delivery of fuels for combustion and the production of nanomaterials all rely on aerosols. Advances in particle measurement technologies have made it possible to take advantage of rapid changes in both particle size and concentration. Likewise, aerosols can now be produced in a controlled fashion. Reviewing many technological applications together with the current scientific status of aerosol modelling and measurements, this book includes: Satellite aerosol remote sensing The effects of aerosols on climate change Air pollution and health Pharmaceutical aerosols and pulmonary drug delivery Bioaerosols and hospital infections Particle emissions from vehicles The safety of emerging nanomaterials Radioactive aerosols: tracers of atmospheric processes With the importance of this topic brought to the public's attention after the eruption of the Icelandic volcano Eyjafjallajökull, this book provides a timely, concise and accessible overview of the many facets of aerosol science.

Book Description
The #1 guide to aerosol science and technology -now better than ever Since 1982, Aerosol Technology has been the text of choice among students and professionals who need to acquire a thorough working knowledge of modern aerosol theory and applications. Now revised to reflect the considerable advances that have been made over the past seventeen years across a broad spectrum of aerosol-related application areas - from occupational hygiene and biomedical technology to microelectronics and pollution control -this new edition includes: * A chapter on bioaerosols * New sections on resuspension, transport losses, respiratory deposition models, and fractal characterization of particles * Expanded coverage of atmospheric aerosols, including background aerosols and urban aerosols * A section on the impact of aerosols on global warming and ozone depletion. Aerosol Technology, Second Edition also features dozens of new, fully worked examples drawn from a wide range of industrial and research settings, plus new chapter-end practice problems to help readers master the material quickly.

Book Description
All papers have been peer-reviewed. The International Radiation Symposium (IRS) is organized every four years by the International Radiation Commission (IRC) and this book presents a compilation on the current problems in atmospheric radiation, from theory and modeling to measurements and applications on weather and climate, from spectroscopy to satellite remote sensing of the many land-ocean-atmosphere components.

Book Description
"This edition reflects the changes which have occurred in spray drying technology and plant design since the publication of the fourth edition. The author argues that spray drying will remain the most important dehydration technique available to convert pumpable fluid feedstocks into powders. Topics covered include the drying principles, a survey of auxiliary equipment and the applications of spray drying in industry. There is a new chpater on spray drying in environmental control and there is a list of spray drying patents issued within the last five years. This edition also contains more data and tables that cover operation and design information for a wide range of products."--Provided by the publisher.

Book Description
Note for the electronic edition: This draft has been assembled from information prepared by authors from around the world. It has been submitted for editing and production by the USDA Agricultural Research Service Information Staff and should be cited as an electronic draft of a forthcoming publication. Because the 1986 edition is out of print, because we have added much new and updated information, and because the time to publication for so massive a project is still many months away, we are making this draft widely available for comment from industry stakeholders, as well as university research, teaching and extension staff.

Book Description
The fluidized-bed reactor is the centerpiece of industrial fluidization processes. This book focuses on the design and operation of fluidized beds in many different industrial processes, emphasizing the rationale for choosing fluidized beds for each particular process. The book starts with a brief history of fluidization from its inception in the 1940’s. The authors present both the fluid dynamics of gas-solid fluidized beds and the extensive experimental studies of operating systems and they set them in the context of operating processes that use fluid-bed reactors. Chemical engineering students and postdocs as well as practicing engineers will find great interest in this book.
