This is a self-contained and systematic account of affine differential geometry from a contemporary view, not only covering the classical theory, but also introducing more modern developments. In order both to cover as much as possible and to keep the text of a reasonable size, the authors have concentrated on the significant features of the subject and their relationship and application to such areas as Riemannian, Euclidean, Lorentzian and projective differential geometry. In so doing, they also provide a modern introduction to the last. Some of the important geometric surfaces considered are illustrated by computer graphics, making this a physically and mathematically attractive book for all researchers in differential geometry, and for mathematical physicists seeking a quick entry to the subject.

Forensic DNA Evidence Interpretation is the most comprehensive resource for DNA casework available today. Written by leaders in the fields of biology and statistics, the book emphasizes the interpretation of test results and provides the necessary formulae in an easily accessible manner. The book begins by reviewing all pertinent biology, and then provides information on every aspect of DNA analysis, including modern interpretation methods and issues, and contemporary population genetic models available for estimating DNA frequencies or likelihood ratios. Following a chapter on procedures for validating databases, the text presents overviews and performance assessments of both modern sampling uncertainty methods and current paternity testing techniques. Later chapters discuss the latest methods for mixture analysis, LCN (ultra trace) analysis, and non-autosomal (mito, X, and Y) DNA analysis. The text concludes with procedures for disaster victim identification and information on DNA intelligence databases. Supported by numerous tables and over 800 references, this authoritative book provides a link among the biological, forensic, and interpretative domains of the DNA profiling field. It is a valuable resource that allows forensic scientists and technicians, molecular biologists, and attorneys to use forensic DNA evidence to its greatest potential.

Timothy Edward Ward, Jacqueline StedallEnglish scientist Thomas Harriot (c.1560-1621) left his scientific and mathematical findings in a jumble of manuscript sheets that have not been previously published in a form relevant to his method of investigation. Stedall (history of science, Queen's College, Oxford, UK) includes some 140 translated and annotated of the sheets concerned with the solution and structure of polynomial equations. In her introductory essay she explains the importance of the work to mathematics, discussing which contributions were new and how it relates to the works of such figures as Viente, Warner, and Torporley.

Tropical East Asia is home to over one billion people and faces massive human impacts from its rising population and rapid economic growth It has already lost more than half of its forest cover to agriculture and urbanization and has the highest rates of deforestation and logging in the tropics Habitat loss coupled with hunting and the relentless trade in wildlife products threatens all its large and many of its smaller vertebrates Despite these problems the region still supports an estimated 15 25 of global terrestrial biodiversity and a growing environmental awareness means that it is no longer assumed that economic development justifies environmental damage and no longer accepted that this trade off is inevitable Effective conservation action now depends on integrating a clear understanding of the ecological patterns and processes in the region with the varied needs of its human population This third edition continues to provide an overview of the terrestrial ecology of Tropical East Asia from southern China to Indonesia and from Bhutan and Bangladesh to the Ryukyu Islands of Japan It retains the balance between compactness and comprehensiveness of the previous editions and the even handed geographical treatment of the whole region but it updates both

Growth reproduction and geographical distribution of plants are profoundly influenced by their physiological ecology the interaction with the surrounding physical chemical and biological environments This textbook highlights mechanisms that underlie plant physiological ecology at the levels of physiology biochemistry biophysics and molecular biology At the same time the integrative power of physiological ecology is well suited to assess the costs benefits and consequences of modifying plants for human needs and to evaluate the role of plants in natural and managed ecosystems Plant Physiological Ecology Third Edition is significantly updated with many full color illustrations and begins with the primary processes of carbon metabolism and transport plant water relations and energy balance After considering individual leaves and whole plants these physiological processes are then scaled up to the level of the canopy Subsequent chapters discuss mineral nutrition and the ways in which plants cope with nutrient deficient or toxic soils The book then looks at patterns of growth and allocation life history traits and interactions between plants and other organisms Later chapters deal with traits that affect decomposition of plant material and with the
