This new edition of the best-selling computing textbook, previously published by Letts Educational, has been revised and updated to meet the demands of the new modular Computing specifications as offered by the various examining boards from September 2000. It is divided into units which correspond to the modules of the Advanced Subsidiary and Advanced Level Computing offered by the AQA examining board and will be ideal for these courses. Centres using other 'A' Level Computing specifications will find that this comprehensive text covers almost all of the required topics in an accessible and 'student-friendly' way. Additional resources for teachers and students are available from the publisher's website (http://www.payne-gallway.co.uk)

Graph theory experienced a tremendous growth in the 20th century. One of the main reasons for this phenomenon is the applicability of graph theory in other disciplines such as physics, chemistry, psychology, sociology, and theoretical computer science. This textbook provides a solid background in the basic topics of graph theory, and is intended for an advanced undergraduate or beginning graduate course in graph theory.

This second edition includes two new chapters: one on domination in graphs and the other on the spectral properties of graphs, the latter including a discussion on graph energy. The chapter on graph colorings has been enlarged, covering additional topics such as homomorphisms and colorings and the uniqueness of the Mycielskian up to isomorphism. This book also introduces several interesting topics such as Dirac's theorem on k-connected graphs, Harary-Nashwilliam's theorem on the hamiltonicity of line graphs, Toida-McKee's characterization of Eulerian graphs, the Tutte matrix of a graph, Fournier's proof of Kuratowski's theorem on planar graphs, the proof of the nonhamiltonicity of the Tutte graph on 46 vertices, and a concrete application of triangulated graphs.

Reflecting the newest trends in computer science, new and revised material throughout the Second Edition of this book places increased emphasis on abstract data types (ADTs) and object-oriented design. This book continues to offer a thorough, well-organized, and up-to-date presentation of essential principles and practices in data structures using C++. Topics include C++'s I/O and string classes, pointers and dynamic allocation, lists, array-based and linked-list implementations of stacks, queues, searching, inheritance and more. For computer professionals in companies that have computing departments or those who want advanced training in C++.

The third edition of this successful textbook looks again at the influence of natural selection on behavior - an animal's struggle to survive by exploiting resources, avoiding predators, and maximizing reproductive success. In this edition, new examples are introduced throughout, many illustrated with full color photographs. In addition, important new topics are added including the latest techniques of comparative analysis, the theory and application of DNA fingerprinting techniques, extensive new discussion on brood parasite/host coevolution, the latest ideas on sexual selection in relation to disease resistance, and a new section on the intentionality of communication. Written in the lucid style for which these two authors are renowned, the text is enhanced by boxed sections illustrating important concepts and new marginal notes that guide the reader through the text. This book will be essential reading for students taking courses in behavioral ecology.

"An Introduction to Spectroscopy" presents the most fundamental concepts of inorganic chemistry at a level appropriate for first year students and in a manner comprehensible to them. This is true even of 'difficult' topics such as the wave mechanical atom, symmetry elements and symmetry operations, and the ligand group orbital approach to bonding, The book contains many useful diagrams illustrating (among other things) the angular dependence of atomic wave functions the derivation of energy level diagrams for polyatomic molecules; close packed lattices and ionic crystal structures. The diagrams of the periodic variation of atomic and molecular properties, showing trends across periods and down groups simultaneously, are especially instructive. Spectroscopy is presented mainly as a tool for the elucidation of atomic and molecular structures.

Each chapter begins with a clear and concise statement of "What Every First-year Student Should Know About . . ." outlining the background knowledge that the student is assumed to have from previous courses and thus pointing out what topics might need to be reviewed. There are also detailed statements of the objectives of each chapter, a number of worked examples interspersed in the text, and a comprehensive set of problems and exercises to test the student's understanding. Tables of data throughout the text and appendices at the end provide much valuable information.

Animal Physiology presents all the branches of modern animal physiology with a strong emphasis on integration among physiological disciplines, ecology, and evolutionary biology. The book takes an entirely fresh approach to each topic. Its full colour illustration program includes many novel, visually effective features to help students learn. Each of the 28 chapters starts with a brief animal example to engage student interest and demonstrate the value of the material that will be learned. The book includes five entire chapters that apply students' newfound physiological knowledge to curiosity provoking and important topics, including diving by marine mammals, the mechanisms of navigation, and training/disuse effects in muscle. The book is committed to a comparative approach throughout. While mammalian physiology is consistently treated in depth, emphasis is also given to the other vertebrate groups, arthropods, molluscs, and as appropriate additional invertebrates. Concepts and integrative themes are emphasized while giving students the specifics they need. The whole animal is the principal focus of this book. The pages are filled with information on everything from knockout mice and enzyme chemistry to traditional organ physiology, phylogenetic analysis, and applications to human affairs. Always, the central organizing principle for the array of topics presented is to understand whole animals in the environments where they live. Concepts from chemistry, physics, and mathematics are explained so the book will be accessible to science students at the sophomore or higher level. Neurophysiological principles are developed clearly and carefully, to help students understand important concepts in sufficient depth without being overwhelming. Pedagogical aids include embedded summaries throughout chapters, lists of key terms, study questions, partially annotated reference lists, an extensive glossary, and appendices on topics such as units of measure and logarithms. For all three authors, teaching physiology to undergraduate students has been a lifelong priority. The opening three chapters provide background material on physiological basics, cell molecular concepts, transport of solutes and water, ecology, and evolutionary biology. The remaining chapters are organized into five sections: Food, Energy, and Temperature Integrating Systems Muscle and Movement Oxygen, Carbon Dioxide, and Internal Transport Water, Salts, and Excretion

Explains the basics of inorganic chemistry with a primary emphasis on facts; then uses the student's growing factual knowledge as a foundation for discussing the important principles of periodicity in structure, bonding and reactivity. New to this updated edition: improved treatment of atomic orbitals and properties such as electronegativity, novel approaches to the depiction of ionic structures, nomenclature for transition metal compounds, quantitative approaches to acid-base chemistry, Wade's rules for boranes and carboranes, the chemistry of major new classes of substances including fullerenes and silenes plus a chapter on the inorganic solid state.
