This book was released on 2011 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Considéré comme vecteur énergétique du futur, l'hydrogène semble être la solution miracle pour sortir de la crise énergétique et environnementale actuelle. Ceci peut être vrai à condition de résoudre tous les problèmes inhérents à son cycle de vie (production, distribution, stockage et utilisation). Face aux nombreux impacts environnementaux générés au cours de la production d'hydrogène, la complexité de leur évaluation et les éventuelles interactions entre eux, le recours à des méthodes d'évaluation environnementale semble nécessaire. Ainsi, l'Analyse de Cycle de Vie Exergétique (ACVE) a été choisie comme l'outil le plus intéressant pour l'étude des scénarios de production d'hydrogène. Elle va, d'une part, comparer des systèmes de production d'hydrogène dans le but de déterminer lequel est le plus éco-efficace et, d'autre part, localiser leurs possibilités d'amélioration environnementale. Huit scénarios de production d'hydrogène ont été étudiés par cette approche ACVE. Ces scénarios se basent essentiellement sur des techniques de reformage du méthane fossile, du biométhane et du bioéthanol. Les résultats obtenus montrent que les scénarios de production d'hydrogène à partir du méthane fossile, technique mûre et largement utilisée, sont les plus gros consommateurs de ressources abiotiques et les plus émetteurs de gaz à effet de serre (GES). Par contre, le recours au biométhane comme source d'hydrogène peut présenter, dans certaines configurations, une bonne solution. Le profil environnemental d'une filière hydrogène ex-biométhane peut encore être rendu plus attrayant par amélioration du système de digestion anaérobie avec un système de reformage sur site. Le recours au bioéthanol produit à partir du blé comme source d'hydrogène présente des effets néfastes sur l'environnement. En effet, ces procédés sont caractérisés par de grands pouvoirs d'eutrophisation et d'acidification en plus de leurs émissions importantes des gaz effet de serre (GES). Toutefois, le bioéthanol peut constituer une source durable et renouvelable pour la production d'hydrogène si sa production ne nuit pas à l'environnement.

Download or read book The Sounds of Early Cinema written by Richard Abel and published by Indiana University Press. This book was released on 2001-10-03 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sounds of Early Cinema is devoted exclusively to a little-known, yet absolutely crucial phenomenon: the ubiquitous presence of sound in early cinema. "Silent cinema" may rarely have been silent, but the sheer diversity of sound(s) and sound/image relations characterizing the first 20 years of moving picture exhibition can still astonish us. Whether instrumental, vocal, or mechanical, sound ranged from the improvised to the pre-arranged (as in scripts, scores, and cue sheets). The practice of mixing sounds with images differed widely, depending on the venue (the nickelodeon in Chicago versus the summer Chautauqua in rural Iowa, the music hall in London or Paris versus the newest palace cinema in New York City) as well as on the historical moment (a single venue might change radically, and many times, from 1906 to 1910). Contributors include Richard Abel, Rick Altman, Edouard Arnoldy, Mats Björkin, Stephen Bottomore, Marta Braun, Jean Châteauvert, Ian Christie, Richard Crangle, Helen Day-Mayer, John Fullerton, Jane Gaines, André Gaudreault, Tom Gunning, François Jost, Charlie Keil, Jeff Klenotic, Germain Lacasse, Neil Lerner, Patrick Loughney, David Mayer, Domi-nique Nasta, Bernard Perron, Jacques Polet, Lauren Rabinovitz, Isabelle Raynauld, Herbert Reynolds, Gregory A. Waller, and Rashit M. Yangirov.

This book was released on 2020-06-16 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Blockchain is widely considered a new key technology. The Foundation for Technology Assessment (TA-SWISS) has proposed a comprehensive assessment of blockchain technologies. With this publication, TA-SWISS provides the much-needed social contextualisation of blockchain. The first, more technical part of the study takes an in-depth look at how blockchain functions and examines the economic potential of this technology. By analysing multiple real-world applications, the study sheds light on where the blockchain has advantages over traditional applications and where existing technologies continue to be the better solution. The second part of the study examines how blockchain became mainstream. It explores the origins of blockchain in the early history of information technology and computer networks. The study also reveals the impact blockchain has on industrial and public spaces. Finally, it discusses the social implications and challenges of blockchain against the background of a new socio-technical environment.

Download or read book Life Cycle Impact Assessment written by Michael Z. Hauschild and published by Springer. This book was released on 2015-03-24 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a detailed presentation of the principles and practice of life cycle impact assessment. As a volume of the LCA compendium, the book is structured according to the LCIA framework developed by the International Organisation for Standardisation (ISO)passing through the phases of definition or selection of impact categories, category indicators and characterisation models (Classification): calculation of category indicator results (Characterisation); calculating the magnitude of category indicator results relative to reference information (Normalisation); and converting indicator results of different impact categories by using numerical factors based on value-choices (Weighting). Chapter one offers a historical overview of the development of life cycle impact assessment and presents the boundary conditions and the general principles and constraints of characterisation modelling in LCA. The second chapter outlines the considerations underlying the selection of impact categories and the classification or assignment of inventory flows into these categories. Chapters three through thirteen exploreall the impact categories that are commonly included in LCIA, discussing the characteristics of each followed by a review of midpoint and endpoint characterisation methods, metrics, uncertainties and new developments, and a discussion of research needs. Chapter-length treatment is accorded to Climate Change; Stratospheric Ozone Depletion; Human Toxicity; Particulate Matter Formation; Photochemical Ozone Formation; Ecotoxicity; Acidification; Eutrophication; Land Use; Water Use; and Abiotic Resource Use. The final two chapters map out the optional LCIA steps of Normalisation and Weighting.

Download or read book Arctic Shipping written by Frédéric Lasserre and published by Routledge. This book was released on 2019-09-05 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book considers both the present state of Arctic shipping and possible future trends with reference to the various sectors of maritime transportation: cruise tourism, container traffic and bulk shipping. Ports are analysed as tools that support the strategies of coastal states to foster the development of resource extraction, enhance the attractiveness of Arctic shipping lanes and enable the control of maritime activities through coast guard deployment. The aim of this book is to draw a picture of the trends of Arctic shipping. How is traffic evolving in Canada’s Arctic, or along the Northern Sea Route? Are there significant differences between bulk and container shipping segments when considering the Arctic market? How are the ports and the hinterland developing and what are the strategies behind those? How is the legal framework shaping the evolution of maritime transportation? The contributors to this book consider all of these questions, and more, as they map out the prospects for Arctic shipping and analyse in detail the development of Arctic shipping as a result of multi-variable interactions. This book will be key reading for industry professionals and post-graduate students alike.

Download or read book Crying Out for Change written by Deepa Narayan-Parker and published by World Bank Publications. This book was released on 2000 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: A multi-country research initiative to understand poverty from the eyes of the poor, the Voices of the Poor project was undertaken to inform the World Bank's activities and the upcoming World Development Report 2000/01. The research findings are being published in three books: "Can Anyone Hear Us?" gathers the voices of over 40,000 poor women and men in 50 countries from the World Bank's participatory poverty assessments (Deepa Narayan, Raj Patel, Kai Schafft, Anne Rademacher, and Sarah Koch-Schulte, authors). "Crying Out for Change" pulls together new field work conducted in 1999 in 23 countries (Deepa Narayan, Robert Chambers, Meera Shah, and Patti Petesch, authors). "From Many Lands" offers regional patterns and country case-studies (Deepa Narayan and Patti Petesch, editors). Voices of the Poor marks the first time such an exercise has been undertaken in so many developing countries and transition economies around the world. It provides a unique and detailed picture of the life of the poor and explains the constraints poor people face to escape from poverty in a way that more traditional survey techniques do not capture well. Each of the three volumes demonstrates the importance of voice and power in poor people's definition of poverty. Voices of the Poor concludes that we need to expand our conventional views of poverty which focus on income expenditure, education, and health to include measures of voice and empowerment.
