Wave Processes in Solids With Microstructure

In this book, Professor Pinsky gives a self-contained account of the theory of positive harmonic functions for second order elliptic operators, using an integrated probabilistic and analytic approach. The book begins with a treatment of the construction and basic properties of diffusion processes. This theory then serves as a vehicle for studying positive harmonic funtions. Starting with a rigorous treatment of the spectral theory of elliptic operators with nice coefficients on smooth, bounded domains, the author then develops the theory of the generalized principal eigenvalue, and the related criticality theory for elliptic operators on arbitrary domains. Martin boundary theory is considered, and the Martin boundary is explicitly calculated for several classes of operators. The book provides an array of criteria for determining whether a diffusion process is transient or recurrent. Also introduced are the theory of bounded harmonic functions, and Brownian motion on manifolds of negat

Molecular biology techniques have considerably increased our understanding of mechanisms underlying the control of flower initiation, development, function and senescence, processes which can be critically important in managing the yield of agricultural crops. The book covers the molecular and genetic control of flower morphogenesis in particular species and discusses the role and regulation of gene expression in the development, together with action of the male and female gametes in plant reproduction. The considerable variation in longevity of flowers and pattern of senescence are reviewed. The importance of ethylene in the control mechanism is discussed using examples of both ethylene-sensitive and insensitive species. The book will be vital to those researching floral physiology, and a useful reference for undergraduates studying relevant botanical courses.

The key to preserving and managing biodiversity is understanding which processes are important at different scales, and how changes affect different components of biodiversity. In this book, existing theories on diversity are synthesised into a logical framework. Global and landscape-scale patterns of biodiversity are described in the first section. In the second, the spatial and temporal dynamics of diversity are emphasised. The third section develops an integrated set of mechanistic explanations for diversity patterns at the levels of population, community, ecosystem and landscape. Finally, case studies examine diversity patterns in marine and terrestrial ecosystems and the effects of biological invasions. The book concludes with a discussion of the economics of preserving biological diversity. This book will interest research workers and students of ecology, biology and conservation.

This is the second volume in a major new initiative in the study of local history, designed to equip students and amateur enthusiasts with a mastery of the basic techniques and concepts required to pursue the subject in depth. From Family History to Community History explores population movements, spatial divisions and social structures in town and countryside, and gives pointers as to the meaning of 'community'. Regional settings, the idea of 'place', and changes over time are also examined, with special attention being paid to the patterns and the processes of all forms of migration. These themes give rise to new research ideas in family and community history.

Tiko, a tiny island in the Pacific Ocean, faces a tidal wave of D-E-V-E-L-O-P-M-E-N-T, which threatens to demolish ancestral ways and the human spirit. From Sione, who prefers to play cards with his

However well the anatomy of the gastro-intestinal tracts of a wide range of mammals is described and quantified, there can be no real explanation of observed patterns without consideration of the mechanical and chemical properties of the food consumed, and of the digestive stages involved in its processing. This book aims to integrate findings from the many different types of investigations of mammalian digestive systems into a coherent whole. Using the themes of food, form and function, researchers discuss models of digestive processes, linking this with evolutionary aspects of food utilisation. Macroscopic and ultrastructural studies of the gastro-intestinal tract are also presented, as are physiological, ecological and biochemical aspects of the digestion of different food types. The book ends with an integrative chapter, bringing together the themes running through the earlier sections.

Originally published in 1972 (Beacon Press), catching the first wave of widespread interest in environmental issues, this influential work is here reprinted with an extensive new preface by the author

The Cold War ended with an exhilarating wave of events: the toppling of the Berlin Wall, the rise of the dissident poet Vaclav Havel, the revolution in Romania. Americans rejoiced at the dramatic con

This book examines the early work of William Carlos Williams in relationship to a woman's tradition of American poetry, as represented by Mina Loy, Denise Levertov and Kathleen Fraser - three generations of women poets working in or directly from a modernist tradition. Linda Kinnahan traces notions of the feminine and the maternal that develop as Williams seeks to create a modern poetics. The impact of first-wave American feminism is examined through an extended analysis of Mina Loy's poetry as a source of a feminist modernism for Williams. Levertov and Fraser are discussed as poetic daughters of Williams who strive to define their voices as women and to reclaim an enabling poetic tradition. In the process, each woman's negotiations with poetic authority and tradition call into question the relationship of poetic father and daughter. Positioning Williams in relation to these three generations of Anglo-American writing within and descending from the modernist movement, the book pursues

Soil Ecology is an exciting textbook for all those concerned with the environment. The author meets the increasing challenge faced by environmental scientists, ecologists, agriculturalists and biotechnologists for an integrated approach to soil ecology. Intellectually enticing and yet eminently readable, the book sets out both fundamental theory and principle to give the reader a thorough grounding in soil ecology. The author emphasises the interrelations between plants, animals and microbes. The fundamental physical and chemical properties of the soil habitat are clearly set out, enabling the reader to explore and understand the processes of soil nutrient cycling and the ecology of extreme soil environments. The book will appeal to advanced undergraduates and graduates in environmental science, plant science, ecology, microbiology and agriculture.

It teaches in a step-by-step fashion the logical techniques of phonological analysis and the fundamental theories that underpin it. This thoroughly revised and updated edition teaches students how to analyze phonological data, how to think critically about data, how to formulate rules and hypotheses, and how to test them. New to this edition: • Improved examples, over 60 exercises and 14 new problem sets from a wide variety of languages encourage students to practise their own analysis of phonological processes and patterns • A new and updated reference list of phonetic symbols and an updated transcription system, making data more accessible to students • Additional online material includes pedagogical suggestions and password-protected answer keys for instructors

This book was originally published in 1991 when land degradation was becoming recognised as a key issue for world conservation as we approached the end of the twentieth century. The complex relationship between human development and the environment is explored in this book with a particular emphasis on the causes of land degradation processes. Having given a broad overview of what land degradation is and why it is occurring, Dr Barrow goes on to illustrate the problem in the context of different habitat types such as forest, woodland and drylands. The impact of human activities through global pollution and industrial and urban development, as well as conservation efforts, are discussed. Written as an introduction to the topic, this book provides a clear synthesis of ways of understanding the phenomenon of land degradation.

Jaegwon Kim is one of the most pre-eminent and most influential contributors to the philosophy of mind and metaphysics. This collection of essays presents the core of his work on supervenience and mind with two sets of postscripts especially written for the book. The essays focus on such issues as the nature of causation and events, what dependency relations other than causal relations connect facts and events, the analysis of supervenience, and the mind-body problem. A central problem in the philosophy of mind is the problem of explaining how the mind can causally influence bodily processes. Professor Kim explores this problem in detail, criticises the nonreductionist solution of it, and offers a modified reductionist solution of his own. Both professional philosophers and their graduate students will find this an invaluable collection.

Longitudinal research is an essential element in the investigation of human development over time, with considerable advantages over more widely used cross-sectional research designs. This book examines the scope for longitudinal studies in a range of developmental fields, emphasizing the advantages of this approach for the investigation of causal mechanisms and processes and the dynamics of development over the lifespan. It also discusses methodological issues and some of the practical and ethical problems that longitudinal research may present. The distinguished contributors review normal and disordered development in the emotional, cognitive and social domains, including valuable discussions of gene-environment interactions, the maturation of the human brain, and issues relating to ageing.

Rodents are the predominant experimental animals found in life-sciences research laboratories. The body temperature of a rodent is markedly affected by surgical, chemical or environmental manipulation. Because temperature regulation is controlled essentially by a 'holistic' regulatory system, meaning that its responses affect the activities of all other psychological and behavioural processes, it is clear that researchers working with rodents must be familiar with thermoregulatory physiology. With the help of extensive data tables and figures, this book explains the key facets of rodent thermal physiology, including neurological control and gender and intraspecies variations. There is a novel chapter on the effects of trauma, toxic chemicals and other factors. The book should therefore find use in government, academic or industrial laboratories whose researchers are working with rodents.

This book introduces the theory of the structural loading on ships and offshore structures caused by wind, waves and currents, and goes on to describe the applications of this theory in terms of real structures. The main topics described are linear-wave induced motions, loads on floating structures, numerical methods for ascertaining wave induced motions and loads, viscous wave loads and damping, station-keeping and water impact and entry. The applications of the theoretical principles are introduced with extensive use of exercises and examples. Applications covered include conventional ships, barges, high speed marine vehicles, semisubmersibles, tension leg platforms, moored or dynamic positioned ships, risers, buoys, fishing nets, jacket structures and gravity platforms.

Drawing on a multitude of data sets and building on analyses carried out over more than a decade, this book offers a major new theoretical explanation of how ordinary citizens figure out what they favour and oppose politically. Reacting against the conventional wisdom, which stresses how little attention the general public pays to political issues and the lack of consistency in their opinions, the studies presented in this book redirect attention to the processes of reasoning that can be discerned when people are confronted with choices about political issues. These studies demonstrate that ordinary people are in fact capable of reasoning dependably about political issues by the use of judgmental heuristics, even if they have only a limited knowledge of politics and of specific issues.

This volume develops a unifying approach to population studies, emphasising the interplay between modelling and experimentation. Throughout, mathematicians and biologists are provided with a framework within which population dynamics can be fully explored and understood. Aspects of population dynamics covered include birth-death and logistic processes, competition and predator-prey relationships, chaos, reaction time-delays, fluctuating environments, spatial systems, velocities of spread, epidemics, and spatial branching structures. Both deterministic and stochastic models are considered. Whilst the more theoretically orientated sections will appeal to mathematical biologists, the material is presented so that readers with little mathematical expertise can bypass these without losing the main flow of the text.

Fluctuations in fish populations in lakes can cascade through food webs to alter nutrient cycling, algal biomass and primary production. Trophic cascades may interact with nutrients and physical factors to explain most of the variance in lake ecosystem process rates. In this 1993 book, a multidisciplinary research team tests this idea by manipulating whole lakes experimentally, and coordinating this with palaeolimnological studies, simulation modelling, and small-scale enclosure experiments. Consequences of predator-prey interactions, behavioural responses of fishes, diel vertical migration of zooplankton, plankton community change, primary production, nutrient cycling and microbial processes are described. Palaeolimnological techniques enable the reconstruction of trophic interactions from past decades. Prospects for analysing the interaction of food web structure and nutrient input in lakes are explored.

Numerical Mathematics is a unique textbook which presents rudimentary numerical mathematics in conjunction with computational laboratory assignments. No previous knowledge of calculus or linear algebra is presupposed, and thus the book is tailor-made for undergraduate students, as well as prospective mathematics teachers. The material in the book emphasises algorithmic aspects of mathematics, which are made viable through numerical assignments, in which the traditional 'chalk-and-talk' lecturer turns, in part, into a laboratory instructor. The book is not a numerical methods book, containing ready-made computational recipes. Rather, it guides the student to create the algorithm required for any given assignment - expressed in whichever programming language is used - on the basis of the underlying mathematics. The computational assignments cover iterative processes, area approximations, solution of linear systems, acceleration of series summation, interpolative approximations, and const

The study of chiefdoms has moved from a preoccupation with their formal characteristics to a concern with their dynamics as political institutions. The contributors to this volume are interested in how ruling elites retain power through control over production and exchange, and then legitimize that control through an elaborate ideology. The eleven case studies look at particular chiefdoms, originating in specific historical conditions. Despite obvious differences between the chiefdoms, certain common underlying processes are revealed. The collection recognizes how complex and interdependent the sources of power in society are, as well as the forces of instability that constantly threaten to tear the society apart. Chiefdoms offers a rich and varied interpretation of sociopolitical power.

Post-translational modifications are now known to play a fundamental role in regulating the activity, location and function of a wide range of proteins. In plant cells work on different types of post-translational modifications has progressed largely along independent lines. This book brings research workers together to allow an exchange of ideas, and reflects a diversity of interest whilst also revealing common ground. An introductory chapter reviewing recent progress in the field is followed by reviews of protein phosphorylation in bacteria and animals which provide a useful perspective on this subject in plants. Consideration is then given to plant protein kinases and the processes they control. Acylation and glycosylation, and their functions in protein targeting and folding are reviewed, along with the roles of glycoproteins in plant development and of ubiquitination in plant senescence.

Personal Identity, National Identity and International Relations is the first psychological study of nation-building, nationalism, mass mobilisation and foreign policy processes. In a bold exposition of identification theory, William Bloom relates mass psychological processes to international relations. He draws on Freud, Mead, Erikson, Parsons and Habermas to provide a rigorously argued answer to the longstanding theoretical problem of how to aggregate from individual attitudes to mass behaviour. With a detailed analysis of the nation-building experience of preindustrial France and England, William Bloom applies the theory to international relations.

This textbook for advanced level courses in oceanography focuses on the interaction of ecological and physical processes that govern the ocean. The book begins with an introduction to ecology, using f

The Films of Roberto Rossellini traces the career of one of the most influential Italian filmmakers through close analysis of the seven films that mark important turning points in his evolution: The Man with a Cross (1943), Open City (1945), Paisan (1946), The Machine to Kill Bad People (1948–52), Voyage in Italy (1953), General della Rovere (1959) and The Rise to Power of Louis XIV (1966). Beginning with Rossellini's work within the fascist cinema, it discusses his invention of neorealism, a new cinematic style that resulted in several classics during the immediate postwar period. Almost immediately, however, Rossellini's continually evolving style moved beyond mere social realism to reveal other aspects of the camera's gaze, as is apparent in the films he made with Ingrid Bergman during the 1950s; though unpopular, these works had a tremendous impact on the French New Wave critics and directors. Rossellini's late career marks a return to his nonrealist period, now critically reexami

This book examines the love elegies of the Roman poets Tibullus, Propertius and Ovid from the point of view of the way the meanings attributed to the poems arise out of the interests and preoccupations of the cultural situation in which they are read. Each study is centred around a reading of a poem or poems together with a discussion of a variety of sophisticated theoretical approaches. All Latin texts and terms are translated or closely paraphrased. Although the book concentrates on the work of the Roman elegists, the challenging insights it offers into the processes involved in the reading and appropriation of the texts of the past are relevant to scholars and students of classical literature in general, and its discussion of such key issues as history, textuality, representation, discourse, gender, ideology and metaphor will be of concern to those interested in literary theory and cultural studies.

This book applies some of the procedures of modern critical theory (in particular reception-theory, deconstruction, theories of dialogue and the hermeneutics associated with the German philosopher Gadamer) to the interpretation of Latin poetry. Charles Martindale argues that we neither can nor should attempt to return to an 'original' meaning for ancient poems, free from later accretions and the processes of appropriation; more traditional approaches to literary enquiry conceal a metaphysics which has been put in question by various anti-foundationalist accounts of the nature of meaning and the relationship between language and what it describes. From this perspective the author examines different readings of the poetry of Virgil, Ovid, Horace and Lucan, in order to suggest alternative ways in which those texts might more profitably be read. Finally he focuses on a key term for such study 'translation' and examines the epistemological questions it raises and seeks to circumvent.

Deep-Sea Biology provides a comprehensive account of the natural history of the organisms associated with the deep-sea floor, and examines their relationship with this remote and inhospitable environment. In the initial chapters, the authors describe the physico-chemical nature of the deep-sea floor and the methods used to collect and study its fauna. They then go on to discuss the ecological framework by exploring spatial patterns of diversity, biomass, vertical zonation and large-scale distributions. Subsequent chapters review current knowledge of feeding, respiration, reproduction and growth processes in these communities. The unique fauna of hydrothermal vents and seeps are considered separately. Finally, there is a discussion of man's exploitation of deep-sea resources and his use of this environment for waste disposal on the fauna of this, the earth's largest ecosystem.

This book studies later medieval culture [c. 1150–1500] through its central symbol: the eucharist. From the twelfth century onwards the eucharist was designed by the Church as the foremost sacrament. The claim that this ritual brought into presence Christ's own body, and offered it to believers, underpinned the sacramental system and the clerical mediation upon which it depended. The book explores the context in which the sacramental world was created and the cultural processes through which it was disseminated, interpreted and used. With attention to the variety of eucharistic meanings and practices - in procession on the feast of Corpus Christi, devotions, prayers, drama, in dissent, abuse and doubt - the author reveals and considers ways in which a religious culture is used as a language for the articulation of order and power, as well as for the most private explorations. The book moves from the 'design' of the eucharist in the twelfth century to its re-design in the sixteenth - a

The subject of mineralogy is moving away from the traditional systematic treatment of mineral groups toward the study of the behaviour of minerals in relation to geological processes. A knowledge of how minerals respond to a changing geological environment is fundamental to our understanding of many dynamic earth processes. By adopting a materials science approach, An Introduction to Mineral Sciences explains the principles underlying the modern study of minerals, discussing the behaviour of crystalline materials with changes in temperature, pressure and chemical environment. The concepts required to understand mineral behaviour are often complex, but are presented here in simple, non-mathematical terms for undergraduate mineralogy students. After introductory chapters describing the principles of diffraction, imaging and the spectroscopic methods used to study minerals, the structure and behaviour of the main groups of rock-forming minerals are covered, and the role of defects in the

This comprehensive 1992 treatise was the first on electrical trauma in humans. Several of the world's leading experts describe the basic mechanisms of tissue injury in victims of electrical trauma, the complex and varied manifestations of electrical trauma, and clinical treatment protocols. Coverage of the topic is broad, ranging from mathematical models of molecular processes to intra-operative clinical care. The volume describes the basic physiochemical mechanisms responsible for tissue damage and explains the complex and variable ways in which electrical trauma manifests itself. Electrical Trauma serves as an important source of information from a variety of perspectives that contribute to the understanding of the electrical injury problem and development of rational therapy. It is suitable for clinicians in trauma surgery, emergency medicine, plastic surgery, intensive care and burns units and for those with an academic and research interest in the mechanisms and causes of electric

Belonging in the two Berlins is an ethnographic investigation into the meaning of German selfhood during the Cold War. Taking the practices of everyday life in the divided Berlin as his point of departure, Borneman shows how ideas of kin, state, and nation were constructed through processes of mirror-imaging and misrecognition. Using linguistics and narrative analysis, he compares the autobiographies of two generations of Berlins residents with the official version of the lifecourse prescribed by the two German states. He examines the relation of the dual political structure to everyday life, the way in which the two states legally regulated the lifecourse in order to define the particular categories of self which signify Germanness, and how citizens experientially appropriated the frameworks provided by these states. Living in the two Berlins constantly compelled residents to define themselves in opposition to their other half. Borneman argues that this resulted in a de facto divided

Protonic conduction in liquid electrolytes is commonplace but is relatively rare in solids. There is much interest worldwide in proton conducting solids, both from the scientific aspect, as materials with novel properties, but also for their possible applications in high-density solid-state batteries, sensors and other electrochemical devices. This book gives a comprehensive review of proton conductors, including theory, techniques, the materials themselves and applications.

This textbook will provide both undergraduates and practising engineers with an up-to-date and thorough grounding in the concepts of modern digital transmission. The book is not encyclopaedic, rather it selects the key concepts and processes and explains them in a deliberate pedagogic style. These concepts and processes are then illustrated by a number of system descriptions. The book is divided into three parts. The longest, Part II, describes the basic processes of digital transmission, such as matched filter detection, pulse shaping, line coding, channel coding, error detection and correction, etc. Understanding the concepts behind these processes requires a grasp of basic mathematical models, and this is provided in Part I. Finally, to put the processes in context, Part III describes elements of the public switched telephone network. The text is written throughout in a modern, digital context, and is comprehensively illustrated with helpful figures. Although the mathematical models

Biogeography is an increasingly important area for ecology, dynamic biogeography being the study of biological patterns and processes on a broad scale both geographically and temporally. Dynamic Biogeography opens with a survey of the different approaches encountered within the subject. The remainder of the book is arranged into four parts. The first is concerned with patterns of concordance; both quantitative and qualitative classifications are discussed. Geographical trends in species' diversity and biological traits are viewed, with Part 3 leading into areography or the analysis of species ranges. The book is drawn together by an overview of all the scales of variation and a glimpse into the future of biogeography. This book will be of interest primarily to scientists in the fields of ecology and biogeography; but the interdisciplinary approach should appeal to all those involved in the biological sciences.

Information on the evolution, taxonomy, morphology, anatomy, physiology and genetics of grapevines has been scarce and thinly spread in the literature on horticulture and the plant sciences. This book aims to provide a concise but comprehensive overview of the biology and cultivation of the grapevine, accessible to all concerned with viticulture. After a description of the essential features of viticulture, including a concise history from antiquity to modern times, the taxonomy of the grapevine and the evolutionary processes which gave rise to the diversity within the Vitaceae is considered. Particular attention is paid to the genera Vitis and Muscadinia, which are considered a reserve of genetic variation for the improvement of grapevines. A description of the vegetative and reproductive anatomy of the grapevine precedes a full discussion of the developmental and environmental physiology of these fascinating and economically important plants. The concluding chapter considers the pot
