Lattice Boltzmann Modeling : An Introduction for Geoscientists and Engineers
Lattice Boltzmann models have a remarkable ability to simulate single- and multi-phase fluids and transport processes within them. A rich variety of behaviors, including higher Reynolds numbers flows, phase separation, evaporation, condensation, cavitation, buoyancy, and interactions with surfaces can readily be simulated. This book provides a basic introduction that emphasizes intuition and simplistic conceptualization of processes. It avoids the more difficult mathematics that underlies LB models. The model is viewed from a particle perspective where collisions, streaming, and particle-particle/particle-surface interactions constitute the entire conceptual framework. Beginners and those with more interest in model application than detailed mathematical foundations will find this a powerful "quick start" guide. Example simulations, exercises, and computer codes are included. Working code is provided on the Internet
L'astrofilo moderno = The modern amateur astronomer
In less than two decades, amateur astronomy has changed its face. The reason, of course, is technological progress. Cheap but high-quality telescopes, computer-controlled "go-to" mounts, autoguiders, CCD cameras, video cameras and (as always) computers and the Internet are just some of the elements that revolutionized 21st century astronomy. Not only have they made amateur astronomy more "friendly" and fun, but they have also greatly expanded the potential of the amateur astronomer. Martin Mobberley first tackles the basic issues and then analyzes in depth what tools are available on the market. From here he starts to review the revolutionary possibilities that open up for amateur astronomers, from imaging, to spectroscopy, to photometry, to the surveillance of Near-Earth objects - comets and asteroids that can come dangerously close to the Earth.
Land-Use and Land-Cover Change : Local Processes and Global Impacts
The book presents recent estimates of the rates in changes of major land classes such as forest, cropland and pasture. Among the causative mechanisms behind land change, synergetic factor combinations are found to be more common than single key factor explanations. Aggregated globally, multiple impacts of local land changes are shown to significantly affect central aspects of Earth System functioning. Innovative developments and applications in the fields of modeling and scenario construction are presented. Finally, conclusions are drawn about the most pressing implications for the design of appropriate intervention policies, and on new directions and frontiers of research.
Landslides from Massive Rock Slope Failure
Amongst the thematic topics discussed are global frequency, impacts on society, analysis of initial rock slope failure, monitoring of rock slope movement, analysis and modeling of post-failure behaviour, volcanic landslides, and influences of massive rock slope failure on the geomorphological evolution of mountain regions. Regional contributions include reports on rockslides and rock avalanches in Norway, western Canada, the Andes of Argentina, the Karakoram Himalaya, the European Alps, the Appennines, and the mountains of Central Asia.
Landslides : Risk Analysis and Sustainable Disaster Management
Based on contributions to the first General Assembly of the International Consortium on Landslides, this reference and status report emphasizes the mechanisms of different types of landslides, landslide risk analysis, and sustainable disaster management. It comprises the achievements of the ICL over the past three years, since the Kyoto assembly. It consists of three parts: research results of the International Programme on Landslides (IPL); contributions on landslide risk analysis; and articles on sustainable disaster management. The contributions reflect a wide range of topics and concerns, randing from field studies, identification of objects of cultural heritage at landslide risk, as well as landslide countermeasures.
Landscape Analysis and Visualisation : Spatial Models for Natural Resource Management and Planning
This book presents a collection and synthesis of many of these perspectives — perhaps it could only be produced in a land urb- ised in the tiniest of pockets, and yet so daunting with respect to the way non-populated landscapes dwarf its cities. Many travel to Australia to its cities and never see the landscapes — but it is these that give the country its power and imagery. It is the landscapes that so impress on us the need to consider how our intervention, through activities ranging from resource exploitation and settled agriculture to climate change, poses one of the greatest crises facing the modern world. In this sense, Australia and its landscape provide a mirror through which we can glimpse the extent to which our intervention in the world threatens its very existence.
Land-Change Science in the Tropics : Changing Agricultural Landscapes
Land use and land-cover change research over the past decade has focused mainly on contemporary primary land-cover conversions in the tropics and sub-tropics, with considerable resources dedicated to the explanation and prediction of tropical deforestation and often ignoring the dynamism in the world’s agro-pastoral landscapes. This collection integrates cutting-edge research in the social, biogeophysical, and geographical information sciences to understand the human and environmental dynamics that change the type, magnitude and location of land uses and land covers in the changing countryside.This book describes the monitoring of land-cover changes, explains the processes through which land is altered, and describes the development of spatially-explicit models to predict land change. This book illustrates how practitioners have integrated knowledge from the three scientific realms - social, biophysical, and GIScience - that underpin land-change science.
Land Use and Soil Resources
Land-use change is one of the main drivers of many environmental change processes. It influences the basic resources of land use, including the soil. Its impact on soil often occurs so creepingly that land managers hardly contemplate initiating ameliorative or counterbalance measures. Poor land management has degraded vast amounts of land, reduced our ability to produce enough food, and is a major threat to rural livelihoods in many developing countries. To date, there has been no single unifying volume that addresses the multifaceted impacts of land use on soils. This book has responded to this challenge by bringing together renowned academics and policy experts to analyze the patterns, driving factors and proximate causes, and the socioeconomic impacts of soil degradation. Policy measures to prevent irreversible degradation and rehabilitate degraded soils are also identified.
Lake Victoria : Ecology, Resources, Environment
Recently, there has been, and continues to be, a tremendous interest on Lake Victoria and its environs, both locally and internationally. A casual browsing on the Internet indicates that the entries on the Lake have been rising phenomenally. At the same time, the issues discussed are as diverse as they are varied in their treatment of the subject, both in terms of depth and comprehensiveness. The information on Lake Victoria and its environ is scattered, isolated, and sometimes confusing even though documentation on the subject are available. Despite this situation, the fact remains that various people (e. g. , secondary and universitystudents,researchers,practitioners,etc. ,)wouldliketoaccess and know more about the Lake and its environs. Aware of the existing information gap about this world’s second largest fresh water Lake, this book is intended to provide readers with up-to-date information pertaining the Lake. The book gives an in-depth coverage of environmental issues, - source endowment, poverty amidst plenty, development opportunities, challenges and other related issues facing the Lake and its environs. It aims at providing information on the above variables, which hopefully will address the needs of various users.
L’esprit de l’aiguille : L’apport du Yi Jing à la pratique de l’acupuncture = The Spirit of the Needle: The contribution of the Yi Jing to the practice of acupuncture
Acupuncture deciphers and heals human beings in all their mutations. The symbolism of Yi Jing joins the humanism of this Traditional Medicine for a dynamic reading of the changes and transformations at work in human beings. The double reflection generates a global vision of the human being and the approach to patients is changed. After an approach to the state of mind, encountered in these two fields, the author sets out to find the oldest roots of the notions of Yin and Yang. This allows him to identify the main strengths of the constitution of a human being and to deepen its symbolic construction. Three fields of application of this approach are then studied. The Extraordinary Meridians are viewed from a descriptive and behavioral perspective, which makes them extremely lively and familiar. Luo points, human being's relationship points with Reality, are also considered on a practical level using a symbolic reading of the links of Heaven, Earth and Man. Many examples shed light on these aspects. The last application is a detailed and comprehensive presentation of the fundamental and symbolic functions of the twelve main meridians through the hexagrams which correspond to their ancient Shu points. This original book is intended for any practitioner of traditional Chinese medicine curious to broaden their field of investigation. Dr M. Vinogradoff has been practicing acupuncture for 25 years. He is a member of the French Acupuncture Association, the French Acupuncture College and the Ricci Institute. After having published the complete translation of Yi Jing, in 2006 he published a novel, the action of which is set in Ancient China.
Kristian Birkeland : The First Space Scientist
PREFACEThisscientific biography of Kristian Birkeland (1867–1917) was written to bring the story ofa Norwegian national hero to the attention ofthe English-speaking world. Birkeland’sheroic stature was established not on a field of military battle,but in the bitter cold of the Artic wilderness ashe sought to answer basic questions abouthow the Sun controlled northern lights andmag-netic storms. He was also afather of Norsk Hydro one ofNorway’s largest industries. Birkel and died before reaching the age of 50.Because Birkel and never kept adiary, documented information about his family and private life is sparse. Before he died, Olaf Devik, the last of Birke-ffland’s close friends, gave along interview and graciously transferred his personal archive to A.E. Birkeland’s 82 scientific papers and three book-length publications map the progress of his investigations. addressed this book questions that had vexed European scientists for centuries. Why do the northern lights appear overhead when the Earth’s magnetic field is disturbed? How are magnetic storms connected to disturbances on the Sun? To answer these questions Birkeland interpreted his advance laboratory simulations and daring campaigns in the Arctic wilderness in the light of Maxwell’s newly discovered laws of electricity and magnetism. Birkeland’s ideas were dismissed for decades, only to be vindicated when satellites could fly above the Earth’s atmosphere.
Knowing the Salween River : Resource Politics of a Contested Transboundary River
Focuses on the Salween River, shared by China, Myanmar, and Thailand, that is increasingly at the heart of pressing regional development debates. The basin supports the livelihoods of over 10 million people, and within it there is great socio-economic, cultural and political diversity. The basin is witnessing intensifying dynamics of resource extraction, alongside large dam construction, conservation and development intervention, that is unfolding within a complex terrain of local, national and transnational governance. With a focus on the contested politics of water and associated resources in the Salween basin, this book offers a collection of empirical case studies that highlights local knowledge and perspectives. Given the paucity of grounded social science studies in this contested basin, this book provides conceptual insights at the intersection of resource governance, development, and politics of knowledge relevant to researchers, policy-makers and practitioners at a time when rapid change is underway.
Kinetics of Water-Rock Interaction
Systems at the surface of the Earth are continually responding to energy inputs derived from solar radiation or from the radiogenic heat in the interior. These energy inputs drive plate movements and erosion, exposing metastable mineral phases at the Earth’s surface. In addition, these energy fluxes are harvested and transformed by living organisms. As long as these processes persist, chemical disequilibrium at the Earth’s surface will be perpetuated. Chemical disequilibrium is also driven by human activities related to production of food, extraction of water and energy resources, and burial of wastes. To understand how the surface of the Earth will change over time, we must understand the rates at which reactions occur and the chemical feedbacks that relate these reactions across extreme temporal and spatial scales. This book addresses fundamental and applied questions concerning the rates of water-rock interactions driven by tectonic, climatic, and anthropogenic forcings.
Iutam Symposium on Dynamics and Control of Nonlinear Systems with Uncertainty ; Proceedings of the IUTAM Symposium held in Nanjing, China, September 18-22, 2006
The last decade has witnessed an increasing interest towards the dynamics and control of nonlinear engineering systems from the scientists engaged in nonlinear dynamics and the control engineers. Both groups of people have recognized the importance of interaction between nonlinear dynamics and robust control during their efforts to improve the dynamic performance of engineering systems with uncertainty, which comes from either the random excitations, such as wind and earthquake, or the modelling errors of real systems including their sensors, controllers and actuators. The dynamics and control of nonlinear systems with uncertainty, therefore, is a vital interdisciplinary topic related to both stochastic systems and deterministic systems. This volume contains the papers presented at the IUTAM Symposium on Dynamics and Control of Nonlinear Systems with Uncertainty, which was sponsored by the International Union of Theoretical and Applied Mechanics (IUTAM)

Comparative risk assessment and environmental decision making
Decision making in environmental projects is typically a complex and confusing process characterized by trade-offs between socio-political, environmental, and economic impacts. Comparative Risk Assessment (CRA) is a methodology applied to facilitate decision making when various activities compete for limited resources. CRA has become an increasingly accepted research tool and has helped to characterize environmental profiles and priorities on the regional and national level. CRA may be considered as part of the more general but as yet quite academic field of multi-criteria decision analysis (MCDA). Considerable research in the area of MCDA has made available methods for applying scientific decision theoretical approaches to multi-criteria problems, but its applications, especially in environmental areas, are still limited. The papers show that the use of comparative risk assessment can provide the scientific basis for environmentally sound and cost-efficient policies, strategies, and solutions to our environmental challenges.
