Gravity pervades the whole universe; hence buoyancy drives fluids everywhere including those in the atmospheres and interiors of planets and stars. Prime examples of such flows are mantle convection, atmospheric flows, solar convection, dynamo process, heat exchangers, airships and hot air balloons. In this book we present fundamentals and applications of thermal convection and stratified flows.Buoyancy brings in extremely rich phenomena including waves and instabilities, patterns, chaos, and turbulence. In this book we present these topics in a systematic manner. First we present a unified treatment of linear theory that yields waves and thermal instability for stably and unstably-stratified flows respectively. We extend this analysis to include rotation and magnetic field. We also describe nonlinear saturation and pattern formation in Rayleigh-Bénard convection.The second half of the book is dedicated to buoyancy-driven turbulence, both in stably-stratified flow and in thermal convection. We describe the spectral theory including energy flux and show that the thermally-driven turbulence is similar to hydrodynamic turbulence. We also describe large-scale quantities like Reynolds and Nusselt numbers, flow anisotropy, and the dynamics of flow structures, namely flow reversals. Thus, this book presents all the major aspects of the buoyancy-driven flows in a coherent manner that would appeal to advanced graduate students and researchers.
One of the main goals of intermediate energy nuclear physics, which serves an important role as a bridge between nuclear and particle physics, is to construct the theory of strong interaction phenomena in terms of conventional degrees of freedom (nucleons, deltas and mesons) as well as of quark degrees of freedom.The main topics to be discussed at this conference are the interaction of pions and other mesons with nuclei at intermediate energies and the role of mesonic degrees of freedom in nuclear reactions, including photon, hadron and heavy ion induced reactions. Both theoretical and experimental results will be included.Over the past two decades, the Meson Factories, including LAMPF, TRIUMF, and PSI, have provided us with systematic experimental information on hadron-hadron and hadron-nucleus dynamics. Major accelerators of JINR are also suitable for studying problems in Intermediate Energy Nuclear Physics. At the present time, first experiments have been performed with the proton beams at the Moscow Meson Factory of INR. One of the purposes of this conference is to introduce the intermediate-energy physics community to the possibility of utilizing the facilities of JINR and INR during the next decade.
This book explores the origins and significance of the corporate climate action phenomenon, which has attracted increased attention in recent years. It examines how and why, during the 2010s, American, German, and Indian corporations spanning finance, technology, automotive, and energy-intensive industries adopted certain climate practices and converged around the idea that the private sector has a vital role to play in addressing climate change and advancing a low-carbon future. It also considers how policy developments that states widely understood as watersheds, including the 2015 Paris Climate Agreement, simply confirmed what the private sector had long believed: that states lacked answers about how to achieve concerted, ambitious, and effective climate action. It was in this context, amid diminishing expectations for robust state climate action, that select corporations sought to fill a perceived leadership vacuum in an issue area poised to shape future global trends. Providing a novel assessment of the corporate sector as a climate actor, this book evaluates how the shift in the center of gravity in the climate change issue area away from national governments and toward other players may influence world order and impact an international security landscape increasingly defined by non-military challenges.
This book contains the transcripts of the lectures presented at the NATO Advanced study Institute on "Computational Techniques in Quantum Chemistry and Molecular Physics", held at Ramsau, Germany, 4th - 21st Sept. 1974. Quantum theory was developed in the early decades of this century and was first applied to problems in chemistry and molecular physics as early as 1927. It soon emerged however, that it was impossible to con sider any but the simplest systems in any quantita tive detail because of the complexity of Schrodinger's equation which is the basic equation for chemical and molecular physics applications. This remained the si tuation until the development, after 1950, of elec tronic digital computers. It then became possible to attempt approximate solutions of Schrodinger's equa tion for fairly complicated systems, to yield results which were sufficiently accurate to make comparison with experiment meaningful. Starting in the early nineteen sixties in the United States at a few centres with access to good computers an enormous amount of work went into the development and implementation of schemes for approximate solu tions of Schrodinger's equation, particularly the de velopment of the Hartree-Fock self-consistent-field scheme. But it was soon found that the integrals needed for application of the methods to molecular problems are far from trivial to evaluate and cannot be easily approximated.
Traditional strategy assumes stability and predictability. Today's world is better characterised by turbulence, uncertainty, novelty and ambiguity - conditions that contribute disruptive changes and trigger the search for new ways of coping. This book aims to become the premier guide on how to do scenario planning to support strategy and public policy. Co-authored by three experts in the field, the book presents The Oxford Scenario Planning Approach (OSPA). The approach is both intellectually rigorous and practical. Methodological choices and theoretical aspects in practice are detailed in reference to the relevant literatures and grounded in 6 case studies the authors have been involved with. The book makes several contributions to the field, centred on how learning with scenario planning is supported by re-framing and re-perception; how this iterative process can be embedded in corporate or government settings, and how it helps those that it supports to do well in today's world. The book is written in an accessible style and will be a useful introductory text as well as a useful guide for the more experienced scenario planning practitioner and scholar.

Although the expression “responsibility to future generations” is firmly established in public and political vocabulary, its operational meaning and practice are inadequately understood and yet to be systematically evaluated. Moreover, the term has not been successfully translated into viable ethical and theoretical concepts that can guide public policies and actions. How can the modes of governance and established policy priorities become compatible with the well-being of future generations? The primary objective of this book is to identify the conditions of and obstacles to governance for a sustainable future, or future-regarding governance. Governance concerns steering a society over extended periods of time, not responding to particular policy issues. The ideas and strategies proposed by contributors in this book to establish future-regarding governance are based on the theoretical and empirical analyses of the major long-term problems facing advanced democracies in general, and Japan in particular. Japan is an interesting case indeed. Relatively poor climate policy, rapidly decreasing birth rate, aging population, extensive public debt, prolonged economic recession, healthcare and pension systems that urgently require redesigning, hollowing-out of industries and subsequent loss of jobs, deteriorating infrastructures, increasing nuclear waste, and intensifying social polarization have caused a decline in people’s trust in the government and democratic processes. Currently, Japanese citizens are widely circulating their doubts about the social system’s sustainability. This book comprises two parts. In Part I, authors from various disciplinary backgrounds examine the idea of governance for a sustainable future from theoretical perspectives. This part discusses issues associated with future-regarding governance that are wicked in nature, such as the philosophical/ethical foundation on which to base the idea of governance for a sustainable future, major impediments to the development of future-regarding governance, and the modes of thinking and action required by leaders and citizens to realize such governance. Chapters in Part II largely focus on the state of long-term governance in Japan. This part uses empirical and in-depth analyses with cross-sectoral and cross-national policy perspectives to identify the state of future-regarding governance in various policy fields and major sectors or organizations mainly in Japan, while also examining strategies and measures to improve their performance. From this perspective, Western democracies and weak democratic regimes elsewhere will be provided with valuable lessons to avoid fatal policy mistakes, thereby improving future-oriented governance worldwide. By combining theoretical discussions on far-reaching issues and empirical analyses of Japanese cases, the book will shed a new light on governance for a sustainable future.
This thoroughly revised and updated Fourth Edition of a time-honored text provides the reader with a comprehensive introduction to the field of scanning electron microscopy (SEM), energy dispersive X-ray spectrometry (EDS) for elemental microanalysis, electron backscatter diffraction analysis (EBSD) for micro-crystallography, and focused ion beams. Students and academic researchers will find the text to be an authoritative and scholarly resource, while SEM operators and a diversity of practitioners — engineers, technicians, physical and biological scientists, clinicians, and technical managers — will find that every chapter has been overhauled to meet the more practical needs of the technologist and working professional. In a break with the past, this Fourth Edition de-emphasizes the design and physical operating basis of the instrumentation, including the electron sources, lenses, detectors, etc. In the modern SEM, many of the low level instrument parameters are now controlled and optimized by the microscope’s software, and user access is restricted. Although the software control system provides efficient and reproducible microscopy and microanalysis, the user must understand the parameter space wherein choices are made to achieve effective and meaningful microscopy, microanalysis, and micro-crystallography. Therefore, special emphasis is placed on beam energy, beam current, electron detector characteristics and controls, and ancillary techniques such as energy dispersive x-ray spectrometry (EDS) and electron backscatter diffraction (EBSD). With 13 years between the publication of the third and fourth editions, new coverage reflects the many improvements in the instrument and analysis techniques. The SEM has evolved into a powerful and versatile characterization platform in which morphology, elemental composition, and crystal structure can be evaluated simultaneously. Extension of the SEM into a "dual beam" platform incorporating both electron and ion columns allows precision modification of the specimen by focused ion beam milling. New coverage in the Fourth Edition includes the increasing use of field emission guns and SEM instruments with high resolution capabilities, variable pressure SEM operation, theory, and measurement of x-rays with high throughput silicon drift detector (SDD-EDS) x-ray spectrometers. In addition to powerful vendor- supplied software to support data collection and processing, the microscopist can access advanced capabilities available in free, open source software platforms, including the National Institutes of Health (NIH) ImageJ-Fiji for image processing and the National Institute of Standards and Technology (NIST) DTSA II for quantitative EDS x-ray microanalysis and spectral simulation, both of which are extensively used in this work. However, the user has a responsibility to bring intellect, curiosity, and a proper skepticism to information on a computer screen and to the entire measurement process. This book helps you to achieve this goal. Realigns the text with the needs of a diverse audience from researchers and graduate students to SEM operators and technical managers Emphasizes practical, hands-on operation of the microscope, particularly user selection of the critical operating parameters to achieve meaningful results Provides step-by-step overviews of SEM, EDS, and EBSD and checklists of critical issues for SEM imaging, EDS x-ray microanalysis, and EBSD crystallographic measurements Makes extensive use of open source software: NIH ImageJ-FIJI for image processing and NIST DTSA II for quantitative EDS x-ray microanalysis and EDS spectral simulation. Includes case studies to illustrate practical problem solving Covers Helium ion scanning microscopy Organized into relatively self-contained modules – no need to "read it all" to understand a topic Includes an online supplement—an extensive "Database of Electron–Solid Interactions"—which can be accessed on SpringerLink, in Chapter 3
