The pace of human progress accelerated profoundly in the twentieth century, spawning revolutionary advances in medicine, agriculture, and industry. Between 1900 and 2000, the world's population quadru
Tropical glaciers are both highly sensitive indicators of global climate and fresh water reservoirs in some fast developing regions. This book gives a theoretical and practical analysis of tropical glaciology including a useful definition of tropical glacier-climate regimes and the analysis of the main glaciological key variables. The Rwenzori and the Cordillera Blanca are investigated as examples of tropical glacierized mountains. The fluctuations of their glaciers since the end of the Little Ice Age are reconstructed and the probable climatic reasons are discussed. The evidence of great expansions of mountain glaciers throughout the tropics on several occasions during the Quaternary are summarised, examined and then applied and contrasted. The accompanying map of the Rwenzori Mountains National Park at a scale of 1:100,000 shows the spectacular retreat of the glaciers during the last century, and their extensions over half the area of the Park in the last 300,000 years.
Cutting across boundaries of art and science, evolution is a fundamental process that has beguiled thinkers through the ages. This collection draws together world-renowned thinkers and communicators with their own intriguing insights. In these essays they offer a feast of dazzling thoughts and ideas to challenge and enthral the reader. Why and how do civilizations and societies change over time? Why do our cells develop the way they do? Why are some villages still villages while others have grown into vast cities? Can we learn from our evolutionary past to plan a better future for our health and society? Tracing a line from the history of biological evolution, through the evolution of cultures, society, science and the universe, Evolution brings together intriguing parallels from all levels of life. From the evolution of the developing embryo to the evolution of a developing star, common threads develop into a fascinating story.
This book describes the application of high-temperature superconducting materials to microwave devices and systems. It deals with the fundamentals of the interaction between microwaves and superconductors, and includes a basic description of how microwave devices can be constructed using these materials. Since the discovery of high-temperature superconductors in 1986 there has been an enormous effort worldwide to develop and characterize these materials. Work on applications has proceeded more slowly however. Nevertheless, commercial applications are now beginning to be possible, including use in passive microwave devices. The advantages of using high-temperature superconductors in these devices is carefully described by the author, enabling scientists and engineers to form a complete understanding of the subject. The rest of the book is devoted to examples of superconducting microwave filters, antennas and systems. The examples chosen relate not only to what can be achieved at present
Marine phosphorites, the principal raw material for phosphatic fertilizers, do not occur uniformly through time and space. The origin of these unusual sedimentary rocks appears to be related mainly to marine biological productivity, often associated with upwelling currents during certain intervals of geological time. This book examines the environmental setting and resulting phosphorites which formed during the Miocene, one of the major and most recent phosphogenic periods throughout the geologic record. In addition, an oceanographic perspective is given by investigations of modern oceanic environments where phosphorites are presently forming. Together, the geologic and marine approaches provide a complete outlook on this important mineral resource. This book is the third of four reference volumes which together cover the achievements of the International Geological Correlation Programme Project 156 (Phosphorites) during the ten years of the project's existence.
Concern about the effects of global change on our planet's future has driven much research into the last few thousand years of earth history. In contrast, this volume takes a much longer viewpoint to provide a historical perspective to recent and future global change. Over 40 international specialists investigate the reaction of life to global environmental changes, from Cretaceous times to the turn of the century. During this time earth's climate has changed from a very warm, 'greenhouse' phase with no significant ice sheets to today's 'ice-house' world. A wide spectrum of animal, plant and protistan life is discussed, encompassing terrestrial, shallow-marine and deep-marine realms. Each chapter considers a particular taxonomic group, looking first at the general picture and then focusing on more specialized aspects such as extinctions, diversity and biogeography. This volume will form an invaluable reference for researchers and graduate students in paleontology, geology, biology, oce
A good grasp of the theory of structures - the theoretical basis by which the strength, stiffness and stability of a building can be understood - is fundamental to structural engineers and architects. Yet most modern structural analysis and design is carried out by computer, with the user isolated from the processes in action. This book provides a broad introduction to the mathematics behind a range of structural processes. The basic structural equations have been known for at least 150 years, but modern plastic theory has opened up a fundamentally new way of advancing structural theory. Paradoxically, the powerful plastic theorems can be used to examine 'classic' elastic design activity, and strong mathematical relationships exist between these two approaches. Some of the techniques used in this book may be familiar to the reader, and some may not, but each of the topics examined will give the structural engineer valuable insight into the basis of the subject. This lucid volume provid
This first volume takes the story from its beginnings in Ionian philosophy as far as the formation of the Atomic Theory and the first criticisms of it by Plato and Aristotle. The second volume will describe the cosmology of Plato and Aristotle, the attempt by Epicurean opponents to revive Atomism and later developments of the debate in classical philosophy and science up to the sixth century of our era. Both are accessible to anyone interested in the history of science and philosophy, even if they have no specialized knowledge of Greek philosophy and no Greek; but professional scholars too will find much of importance to them.
According to received historiography, the fundamental issue in eighteenth-century optics was whether light could be understood as the emission of particles, or as the motion of waves in a subtle medium. Moreover, the emission theory of light was supposed to have been dominant in the eighteenth century, backed by Newton's physical arguments. This picture is enriched and qualified by focusing on the origins, contents and reception of the wave theory of light, published by Leonhard Euler in 1746, studied in depth in this 1995 book. Contrary to what has been assumed, the particle–wave debate only starts with Euler. When the emission view of light suddenly became dominant in Germany around 1795, it was new chemical experiments that proved crucial. Reflecting on the mathematical, experimental and metaphysical aspects of physical optics, a general picture of early modern science is outlined in the epilogue to the book.
This description of a model system for cell differentiation and organogenesis is written by one of the foremost researchers in the area. The main emphasis is on the mammalian kidney, but the book also deals with the development of the transien excretory organs. It includes discussions of induction, proliferation, early cytodifferentiation and morphogenesis and organogenesis. This authoritative account will be valuable to developmental biologists and also to scientists working in paediatric nephrology. As it gives the background of normal development and of control systems, it will also be of use to nephrologists working on abnormalities in the urinary tract.
Where did SARS come from? Have we inherited genes from Neanderthals? How do plants use their internal clock? The genomic revolution in biology enables us to answer such questions. But the revolution would have been impossible without the support of powerful computational and statistical methods that enable us to exploit genomic data. Many universities are introducing courses to train the next generation of bioinformaticians: biologists fluent in mathematics and computer science, and data analysts familiar with biology. This readable and entertaining book, based on successful taught courses, provides a roadmap to navigate entry to this field. It guides the reader through key achievements of bioinformatics, using a hands-on approach. Statistical sequence analysis, sequence alignment, hidden Markov models, gene and motif finding and more, are introduced in a rigorous yet accessible way. A companion website provides the reader with Matlab-related software tools for reproducing the steps de
