The determination of when, how, how often and with whom an animal breeds is moving rapidly away from evolutionary pressures and towards human purposes: these include the breeding of around 50 billion mammals and birds for food production annually, the breeding of pedigree dogs and cats, racing dogs and horses, specialised laboratory animal strains and the use of reproductive science to conserve endangered species or breeds and to limit unwanted populations of pests and non-native species. But the ethics and sustainability of this takeover of animals' reproductive lives have been insufficiently examined by either professionals or the public. This book discusses the methods, the motivations and the consequences of human intervention in animal breeding in terms of animal health, behaviour and well-being. It explores where we are now and the choices ahead, and looks to a future where we have more respect for animals as sentient beings and where we could loosen the reins of reproductive control.
The climate of our planet is changing at a rate unprecedented in recent human history. The energy absorbed from the sun exceeds what is returned to space. The planet as a whole is gaining energy. The heat content of the ocean is increasing, the surface and atmosphere are warming, mid-latitude glaciers are melting, sea level is rising, and the Arctic Ocean is losing its ice cover. None of these assertions is based on theory but on hard observational facts. Given the science-heavy nature of climate change, debates and discussions have not played as big a role in the public sphere as they should, and instead are relegated to often misinformed political discussions and inaccessible scientific conferences. Michael B. McElroy, an eminent Harvard scholar of environmental studies, combines both his research chops and pedagogical expertise to present a book that will appeal to the lay reader but still be grounded in scientific fact. The book begins with a general introduction, followed by chapters on energy basics, a discussion of the contemporary energy systems of the US and China, and the aforementioned chapters on climate. It continues with a series of chapters on specific energy options: coal, oil, natural gas, nuclear, wind, solar, hydro, geothermal, and biomass. The perspective is global but with a specific focus on the US and China recognizing the critical role these countries must play in addressing the challenge of global climate change. The book concludes with a discussion of initiatives now underway to at least reduce the rate of increase of greenhouse gas emissions, together with a vision for a low carbon energy future that could in principle minimize the long-term impact of energy systems on global climate.

Recent progress in numerical methods and computer science allows us today to simulate the propagation of seismic waves through realistically heterogeneous Earth models with unprecedented accuracy. Full waveform tomography is a tomographic technique that takes advantage of numerical solutions of the elastic wave equation. The accuracy of the numerical solutions and the exploitation of complete waveform information result in tomographic images that are both more realistic and better resolved. This book develops and describes state of the art methodologies covering all aspects of full waveform tomography including methods for the numerical solution of the elastic wave equation, the adjoint method, the design of objective functionals and optimisation schemes. It provides a variety of case studies on all scales from local to global based on a large number of examples involving real data. It is a comprehensive reference on full waveform tomography for advanced students, researchers and professionals.
The International Mining Forum is a recurring event, hosted by the University of Science and Technology in Cracow, Poland, bringing together an international group of scientists, including those working in rock mechanics and computer engineering as well as mining engineers. The topics are wide-ranging, including papers on remote sensing to assess primary impact; treatment of sealed-off coal mine fires; sustainable development in mine closure; and monitoring of natural hazards and safety issues.
This book introduces a methodology for solving the seismic inverse problem using purely numerical solutions built on 3D wave equations and which is free of the approximations or simplifications that are common in classical seismic inversion methodologies and therefore applicable to arbitrary 3D geological media and seismic source models. Source codes provided allow readers to experiment with the calculations demonstrated and also explore their own applications.
Across the globe, controversies around vaccines exemplify anxieties thrown up by new technologies. Whether it is growing parental concerns over the MMR vaccine in the UK or Nigerian communities refusing polio vaccines-associating them with genocidal policies-these controversies feed the cornerstone debates of our time concerning trust in government, media responsibility, scientific impartiality, citizen science, parental choice and government enforcement. This book is a groundbreaking examination of how parents are reflecting on and engaging with vaccination, a rapidly advancing and universally applied technology. It examines the anxieties emerging as today's highly globalized vaccine technologies and technocracies encounter the deeply intimate personal and social worlds of parenting and childcare, showing these to be part of transforming science-society relations. The authors interweave rich ethnographic data from participant-observation, interviews, group discussions and parental narratives from the UK and West Africa with the findings of large-scale surveys, which reveal more general patterns. The book takes a comparative approach and draws perspectives from medical anthropology, science and technology studies and development studies into engagement with public health and vaccine policy. The authors show how vaccine controversies involve relations of knowledge, responsibility and interdependence across multiple scales that challenge easy dichotomies: tradition versus modernity, reason versus emotion, personal versus public, rich versus poor, and Northern risk society versus Southern developing society. They reflect critically on the stereotypes that at times pass for explanations ofparents' engagement with both routine vaccination and vaccine research, suggesting some routes to improved dialogue between health policy-makers, professionals and medical researchers, and the people they serve. More broadly, the book suggests new terms of debate for thinking about science-society relations in a globalized world.
Magnetometry for Archaeologists covers the most widely used method for archaeological surveying. Authors Arnold Aspinall, Chris Gaffney, and Armin Schmidt recount the history of magnetometers from their inception through today's state-of-the-art detectors, explain the physics behind the different types of sensors, and describe the most fruitful ways in which the technology can be employed. They also consider the theoretical and practical uses of magnetometry from for many archaeological periods and regions. The reader learns exactly what magnetometry measures, and how knowledge gained from it influences the ways in which surveys are undertaken. The authors also discuss the potential for and the problems associated with the use, display, and interpretation of buried remains. View the book's Acknowledgments.
Fracture and flow of rocks under stress and their geophysical and seismological implications raise fundamental questions in rock mechanics, particularly in the areas of tectonophysics and seismology. This text exclusively addresses the deformation and fracture of rock specimens under general triaxial compression, in which all three principal stresses are different; which significantly affects the ultimate strength of rocks. It moreover deals with deformation and failure folloiwng intermediate principal stress in graphic and numerical form. The effect of the intrinsic features of rock masses of inhomogeneous or anisotropic structure are taken into account, as are acoustic emission phenomena in rocks under various stress states. Friction in rocks, measured by a newly-designed shear-testing machine, is discussed in relation to earthquake phenomena.
Planetary Tectonism across the Solar System, Volume Two in the Comparative Planetology series, addresses key questions surrounding planetary tectonism, such our understanding of the global contraction of Mercury, the formation of giant rift zones on Saturn’s icy moons, or the tesserated terrain on Venus. The book makes connections to Earth, such as how deformation on Mercury is both similar and different, and how to apply theoretical considerations behind plate tectonics on Earth to other planets. The book offers up-to-date, accessible and comprehensive discussions on the major tectonic processes and landforms that shape and drive the evolution of planets, moons and smaller bodies. By placing a singular emphasis on comparing tectonic processes and landforms on all relevant Solar System bodies, with the explicit objective of providing a systems-level understanding of this widespread phenomenon, this book is ideal for anyone studying planetary tectonism.

Ring lasers are commonly used as gyroscopes for aircraft navigation and attitude control. The largest ring lasers are sensitive enough that they can be used for high resolution inertial rotation sensing of the Earth in order to detect tiny perturbations to the Earth's rotation caused by earthquakes or global mass transport. This book describes the latest advances in the development of large ring lasers for applications in geodesy and geophysics using the most sensitive and stable devices available. Chapters cover our current knowledge of the physics of the laser gyroscope, how to acquire and analyse data from ring lasers, and what the potential applications are in the geosciences. It is a valuable reference for those working with ring lasers or using the data for applications in geodesy and geophysics; as well as researchers in laser physics, photonics and navigation.
A concise introduction to geophysical data processing - many of the techniques associated with the general field of time series analysis - for advanced students, researchers, and professionals. The textbook begins with calculus before transitioning to discrete time series via the sampling theorem, aliasing, use of complex sinusoids, development of the discrete Fourier transform from the Fourier series, and an overview of linear digital filter types and descriptions. Aimed at senior undergraduate and graduate students in geophysics, environmental science, and engineering with no previous background in linear algebra, probability, or statistics, this textbook draws scenarios and datasets from across the world of geophysics, and shows how data processing techniques can be applied to real-world problems using detailed examples, illustrations, and exercises (using MATLAB or similar computing environment). Online supplementary resources include datasets for students, and a solutions manual and all the figures from the book as PowerPoints for course instructors.
A century ago, Lewis Fry Richardson introduced the concept of energy cascades in turbulence. Since this conceptual breakthrough, turbulence has been studied in diverse systems and our knowledge has increased considerably through theoretical, numerical, experimental and observational advances. Eddy turbulence and wave turbulence are the two regimes we can find in nature. So far, most attention has been devoted to the former regime, eddy turbulence, which is often observed in water. However, physicists are often interested in systems for which wave turbulence is relevant. This textbook deals with wave turbulence and systems composed of a sea of weak waves interacting non-linearly. After a general introduction which includes a brief history of the field, the theory of wave turbulence is introduced rigorously for surface waves. The theory is then applied to examples in hydrodynamics, plasma physics, astrophysics and cosmology, giving the reader a modern and interdisciplinary view of the subject.
High pressure mineral physics is a field that has shaped our understanding of deep planetary interiors and revealed new material phenomena occurring at extreme conditions. Comprised of sixteen chapters written by well-established experts, this book covers recent advances in static and dynamic compression techniques and enhanced diagnostic capabilities, including synchrotron X-ray and neutron diffraction, spectroscopic measurements, in situ X-ray diffraction under dynamic loading, and multigrain crystallography at megabar pressures. Applications range from measuring equations of state, elasticity, and deformation of materials at high pressure, to high pressure synthesis, thermochemistry of high pressure phases, and new molecular compounds and superconductivity under extreme conditions. This book also introduces experimental geochemistry in the laser-heated diamond-anvil cell enabled by the focused ion beam technique for sample recovery and quantitative chemical analysis at submicron scale. Each chapter ends with an insightful perspective of future directions, making it an invaluable source for graduate students and researchers.
Although upwards of 50,000 environmental assessments (EAs) are prepared annually-compared to some 500 environmental impact statements (EISs)-the focus of U.S. National Environmental Policy Act (NEPA) regulations is on defining requirements for preparing EISs. Written by Charles Eccleston and J. Peyton Doub, who have established themselves among the top environmental experts in the world, Preparing NEPA Environmental Assessments: A User's Guide to Best Professional Practices fills the need for an authoritative and comprehensive guide on how to prepare EAs. Bridging the regulatory gap, this book identifies relevant EIS regulatory requirements that can be logically interpreted to also apply to EAs. It compiles and synthesizes information scattered throughout NEPA's regulations, executive orders, and guidance documents, and incorporates case law to provide additional clarification. The authors also draw on the professional experiences and best professional practices (BPP) of NEPA practitioners. From the fundamentals to more advanced topics, the book presents a consistent methodology to help beginners, students, and professionals manage, analyze, and write legally sufficient EAs. It addresses dilemmas that have traditionally plagued preparation of EAs, provides BPPs, tools, and approaches for resolving problems, and introduces methods for streamlining the EA process. Building on Eccleston's previous guide to EAs, Effective Environmental Assessments: How to Manage and Prepare NEPA Assessments (2001), this book reflects the rapid changes in government policy over the past ten years. An indispensable source of practical information, it provides readers with step-by-step direction and best practices for preparing defensible EAs.

Fundamentals of Seismic Wave Propagation, published in 2004, presents a comprehensive introduction to the propagation of high-frequency body-waves in elastodynamics. The theory of seismic wave propagation in acoustic, elastic and anisotropic media is developed to allow seismic waves to be modelled in complex, realistic three-dimensional Earth models. This book provides a consistent and thorough development of modelling methods widely used in elastic wave propagation ranging from the whole Earth, through regional and crustal seismology, exploration seismics to borehole seismics, sonics and ultrasonics. Particular emphasis is placed on developing a consistent notation and approach throughout, which highlights similarities and allows more complicated methods and extensions to be developed without difficulty. This book is intended as a text for graduate courses in theoretical seismology, and as a reference for all academic and industrial seismologists using numerical modelling methods. Exercises and suggestions for further reading are included in each chapter.
The Sun and stars rotate in di?erent ways and at di?erent velocity rates. The knowledge of how they rotate is important in understanding the formation and evolution of stars and their structure. The closest star to our Earth, the Sun, is a good laboratory to study in detail the rotation of a G star and allows to test new ideas and develop new techniques to study stellar rotation. More or less massive, more or lessevolved objects, however, can have averydi?erent rotation rate, structure and history. In recent years our understanding of the rotation of the Sun has greatly improved. The Sun has a well-known large-scale rotation, which can be m- sured thanks to visible features across the solar disk, such as sunspots, or via spectroscopy. In addition, several studies cast light on di?erential rotation in the convective zone and on meridional circulation in the radiative zone of the Sun. Even the rotation of the core of the Sun can now be studied thanks to various methods, such as dynamics of the gravitational moments and of course, helioseismology, through g-modes analysis. Moreover, the magnetic ?eld is strongly linked to the matter motions in the solar plasma. The solar magnetic ?eld can be measured only at the surface or in theupperlayers.Itistheproductoftheinternaldynamoorofthelocaldynamos if they exist - in any case magnetic ?eld and rotation cannot thus be separated.
