Book excerpt: Les océans et la banquise jouent un rôle important dans le système climatique et météorologique. Une future mission satellite en micro-ondes passives basses fréquences, conçue pour observer les régions polaires est actuellement à l'étude à l'Agence Spatiale Européenne pour l'expansion du programme Copernicus. Les observations satellites en micro-ondes passives permettent une observation de la surface de la Terre par tous temps, aussi bien de jour que de nuit. Dans cette thèse, nous nous intéressons à l'estimation des paramètres de surface de l'océan et de la banquise à partir des observations satellites micro-ondes passives basses fréquences. L'objectif est de développer de nouvelles méthodes d'estimation de ces paramètres qui soient plus efficaces et adaptées à la future mission satellite micro-onde passive CIMR (Copernicus Imaging Microwave Radiometer). La première partie de la thèse traite de l'estimation des paramètres océaniques tels que la température de la surface de la mer, la salinité et la vitesse du vent océanique. La deuxième partie traite de l'estimation des paramètres de la banquise tels que la concentration en glace, l'épaisseur de neige et la température d'interface neige-glace. Enfin, avec les méthodes développées dans cette thèse les performances de la mission CIMR sont évaluées et comparées à celles des missions actuelles.

Book excerpt: ‘An interesting and important account.’ Daily Telegraph Have you ever stopped and wondered where your jeans came from? Who made them and where? Ever wondered where they end up after you donate them for recycling? Following a pair of jeans, Clothing Poverty takes the reader on a vivid around-the-world tour to reveal how clothes are manufactured and retailed, bringing to light how fast fashion and clothing recycling are interconnected. Andrew Brooks shows how recycled clothes are traded across continents, uncovers how retailers and international charities are embroiled in commodity chains which perpetuate poverty, and exposes the hidden trade networks which transect the globe. Stitching together rich narratives, from Mozambican markets, Nigerian smugglers and Chinese factories to London’s vintage clothing scene, TOMS shoes and Vivienne Westwood’s ethical fashion lines, Brooks uncovers the many hidden sides of fashion.

This book was released on 2005 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: In March, 2004, Water Survey of Canada and the Canadian Society for Hydrological Sciences co-hosted a workshop in Yellowknife to discuss how to improve our community's abilities to predict streamflow in the Mackenzie Valley and similar cold regions of Canada. The workshop's objectives were to: 1) provide outreach to practitioners of the results of recent studies in cold water regions hydrological regimes in the context of predicting streamflow; 2) assess "state of the art" techniques to predict streamflow in ungauged basins in northern landscapes, and; 3) define technical needs and recommend a research agenda that can deliver these over the next decade. This book summarizes presentations by invited speakers on the subjects of: statisical hydrology and hydrometric network planning; cold regions hydrological processes; application of hydrological models to cold regions; and advances in distributed hydrological modelling.

Book Synopsis 'Being Alive Well' by : Naomi Adelson
Download or read book 'Being Alive Well' written by Naomi Adelson and published by University of Toronto Press. This book was released on 2000-12-15 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Being Alive Well': Health and the Politics of Cree Well-Being is a critical medical anthropological analysis of health theory in the social sciences with specific reference to the James Bay Cree of northern Quebec. In it the author argues that definitions of health are not simply reflections of physiological soundness but convey broader cultural and political realities. The book begins with a treatise on the study of health in the social sciences and a call for a broader understanding of the cultural parameters of any definition of health. Following a chapter that outlines the history of the Whapmagoostui (Great Whale River) region and the people, Adelson presents the underlying symbolic foundations of a Cree concept of health, or miyupimaatisiiun. The core of this book is an ethnographic study of the Whapmagoostui Cree and their particular concept of "health" (miyupimaatisiiun or "being alive well"). That concept is mediated by history, cultural practices, and the contemporary world of the Cree, including their fundamental concerns about their land and culture. In the contemporary context, health – or more specifically, "being alive well" – for the Cree of Great Whale is an intimate fusion of social, political, and personal well-being, thus linking individual bodies to a larger socio-political reality.

Download or read book Cities at Risk written by Helene Joffe and published by Springer Science & Business Media. This book was released on 2013-03-27 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the major growth of the world’s population over the past century, as well as rapid urbanisation, people increasingly live in crowded cities. This trend is often accompanied by proliferation of poorly built housing, uncontrolled use of land, occupation of unsafe environments and overstretched services. When a natural hazard strikes such a city many people are vulnerable to loss of life and property. This book explores what these people think and feel about the threats that they face. How do they live with perils ranging from earthquakes to monsoons, from floods to hurricanes, in the 21st century? The authors are drawn from a large range of disciplines: Psychology, Engineering, Geography, Anthropology and Urban Planning. They also reflect on how perils are represented in multiple cultures: the United States, Japan, Turkey, Bangladesh, the United Kingdom and New Zealand. The book therefore not only brings to light the ways that different cultures represent natural hazards but also the different ways in which various disciplines write about living with perils in the 21st century. The book is addressed both to researchers and to organizations involved with risk management and risk mitigation.

Book Synopsis Climate and the British Scene by : Gordon Manley
Download or read book Climate and the British Scene written by Gordon Manley and published by . This book was released on 1962 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: From Chaucer's sweet April showers to the peasoupers of Sherlock Holmes the British scene cannot be contemplated without climate entering in. This edition is exclusive to newnaturalists.com In this book Professor Manley shows us the best and worst of our much-maligned climate. He traces the subtle influence of sunshine and cloud, of dew, mist, rain, hail and snow, of heat and cold on the changing scene through the seasons. We often apologise for our climate, but in many ways it is the best in the world. No great extremes of heat or cold, no dreaded droughts, no destructive hurricanes, yet a marked seasonal rhythm with lots of little surprises. The richness of plant and animal life, the extremely high productivity of our farmlands, the fleeting beauties of our landscape - all are closely linked with Britain's climate. It may justly be claimed that this is the first book to attempt scientifically to trace these intimate yet elusive relationships.
Book Synopsis Land Ocean Interaction by : D. Huntley
Download or read book Land Ocean Interaction written by D. Huntley and published by IWA Publishing. This book was released on 2000-12-01 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The UK Land-Ocean Interaction Study (LOIS) provided a major opportunity to measure and model the processes controlling the fluxes of materials between river basins and coastal seas. The main programme of research took place between 1992 and 1998, funded by the UK Natural Environment Research Council, and involved approximately 360 coastal researchers contributing to more than 70 collaborative projects. This book presents accessible summaries of key results of this research. The ten chapters of the book are written by leading contributors to the programme, and cover aspects of the physical, sedimentological, chemical and biological processes controlling fluxes between river catchments and coastal seas in temporate environments. Major overarching themes for all of the chapters include the persistence, storage, degradation and transport of pollutants from catchment to coastal sea, and an emphasis on the relevance of research for river and coastal water quality management. The chapters also describe a number of important technological advances in the measurement of processes and longer term monitoring of the fluvial, estuarine and coastal environments. Approaches to monitoring were also transferred between disciplines, in many cases for the first time. The rivers and coastal programme of LOIS was unique in its scale and inter-disciplinarity and its results are of lasting value. This book provides a useful and important summary of many of its results and an effective introduction to the research for those who want to delve more deeply into the data and published papers. It will be of interest to scientists, environmental managers and scientific policy makers.
