By extracting the fundamental concepts from this enormous and ever-growing field, the authors tell the story of cell biology, and create a coherent framework through which non-expert readers may approach the subject. Written in clear and concise language, and beautifully illustrated, the book is enjoyable to read, and it provides a clear sense of the excitement of modern biology. Molecular Biology of the Cell sets forth the current understanding of cell biology (completely updated as of Autumn 2001), and it explores the intriguing implications and possibilities of the great deal that remains unknown. The hallmark features of previous editions continue in the Fourth Edition. The book is designed with a clean and open, single-column layout. The art program maintains a completely consistent format and style, and includes over 1,600 photographs, electron micrographs, and original drawings by the authors. Clear and concise concept headings introduce each section. Every chapter contains extensive references. Most important, every chapter has been subjected to a rigorous, collaborative revision process where, in addition to incorporating comments from expert reviewers, each co-author reads and reviews the other authors' prose.

    In this book, Richlin argues that the attitude of sexual aggressiveness in defense of a bounded area serves as a model for Roman satire from Lucilius to Juvenal. Using literary, anthropological, psychological, and feminist methodologies, she suggests that aggressive sexual humor reinforces aggressive behavior on both the individual and societal levels, and that Roman satire provides an insight into Roman culture. Including a substantial and provocative new introduction, this revised edition is important not only as an in-depth study of Roman sexual satire, but also as a commentary on the effects of all humor on society and its victims.

    First published in the 1800s, "Ray's Arithmetics" are organized in an orderly manner around the discipline of arithmetic itself. They present principles and follow up each one with examples which include difficult problems to challenge the best students. Students who do not master a concept the first time can return to it later, work the more difficult problems, and master the concepts. Thus in these compact volumes is a complete arithmetic course to study in school, to help in preparation for ACT and SAT tests, and to use for reference throughout a lifetime. In order to capture the spirit of the original Ray's, the publishers of this edition have refrained from revising the problems and prices. Only a few words have been changed. Thus students will have to rely on their arithmetic ability to solve the problems. Also the charm of a former era lives on in this reprinting. Flour and salt are sold by the barrel, kegs may contain tar, and postage stamps cost three cents each. Through this content, students learn social history of the 1800s in a unique, hands-on manner at the same time they are mastering arithmetic. Primary Arithmetic: Reading, writing and understanding numbers to 100; adding and subtracting with sums to 20; multiplication and division to 10s.

    At the same time, the text provides readers with the familiar feel common to texts on engineering subjects, helping to make a coursework on probability and statistics a more pleasant and meaningful learning experience. Important features include: all examples and problems are written with the prospective engineer in mind; wherever possible, real data are used in examples, problems and illustrations; the second edition thoroughly integrates the computer, and many examples are illustrated with printouts using SPSS, SAS and other software.

    This is meant to emphasize that this volume has been written as a general course in modern analysis on a graduate student level and not only as the beginning of a specialized course in partial differen tial equations. In particular, it could also serve as an introduction to harmonic analysis. Exercises are given primarily to the sections of gen eral interest; there are none to the last two chapters. Most of the exercises are just routine problems meant to give some familiarity with standard use of the tools introduced in the text. Others are extensions of the theory presented there. As a rule rather complete though brief solutions are then given in the answers and hints. To a large extent the exercises have been taken over from courses or examinations given by Anders Melin or myself at the University of Lund. I am grateful to Anders Melin for letting me use the problems originating from him and for numerous valuable comments on this collection. As in the revised printing of Volume II, a number of minor flaws have also been corrected in this edition. Many of these have been called to my attention by the Russian translators of the first edition, and I wish to thank them for our excellent collaboration."

    Intent on questioning the meaning of the antitraditionalist impulse in today's society, Shils argues here that the tendency to distrust and rebel against tradition is at the heart of tradition itself; only through suspicion and defiance does tradition actually move forward. Revealing the importance of tradition to social and political institutions, technology, science, literature, religion, and scholarship, Tradition remains the definitive work on this vital element of our society. "Shils is a man of fabled learning, whose mind purrs powerfully like the moth at dusk. I hesitate to use the word conservative of him because it misses the central concern of his work, which is not conservatism, but the conservation of those human resources and achievements which are richest, and matter most."—David A. Martin, Times Literary Supplement "Tradition is the first comprehensive treatment of the subject that encompasses the totality of tradition in all its multifaceted variables and functions. . . . It is a landmark analytical and theoretical sociological study that not only fills a need but also provides a basic model and impetus for further research."—H. Leon Abrams Jr., Sociology

    The examples and the statistical methods are laid out with unusual clarity by the simple device of using special formats for each. The book was written with great care and is extremely user-friendly."--The UMAP JournalAlthough the goals and procedures of statistical research have changed little since the Second Edition of Statistics for Research was published, the almost universal availability of personal computers and statistical computing application packages have made it possible for today's statisticians to do more in less time than ever before.The Third Edition of this bestselling text reflects how the changes in the computing environment have transformed the way statistical analyses are performed today. Based on extensive input from university statistics departments throughout the country, the authors have made several important and timely revisions, including: Additional material on probability appears early in the textNew sections on odds ratios, ratio and difference estimations, repeated measure analysis, and logistic regressionNew examples and exercises, many from the field of the health sciencesPrintouts of computer analyses on all complex proceduresAn accompanying Web site illustrating how to use SAS(R) and JMP(R) for all proceduresThe text features the most commonly used statistical techniques for the analysis of research data. As in the earlier editions, emphasis is placed on how to select the proper statistical procedure and how to interpret results. Whenever possible, to avoid using the computer as a "black box" that performs a mysterious process on the data, actual computational procedures are also given.A must for scientists who analyze data, professionals and researchers who need a self-teaching text, and graduate students in statistical methods, Statistics for Research, Third Edition brings the methodology up to date in a very practical and accessible way.

    The med term approaches and how they differ Most med terms books teach by memorization the whole word approach. Memorize vocabulary and then try to recognize word patterns. Gylys uses the word-building approach. First learn the patterns of medical words before you learn the vocabulary. Why does word-building work? It begins with the basics Gylys takes a common sense approach, by introducing word elements first: Roots Combining forms Suffixes Prefixes She covers them one by one, breaking down each word part. Common English word elements are presented This familiarity makes it easier for students to learn and break apart and build words. Students can use their understanding of word parts to decipher vocabulary. Mnemonic devices, interactive activities (in the book and on the CD) make word-building fun and this in turn increases retention no more tedious memorization, students learn by breaking down and rebuilding words From my years of teaching, I found it was much easier for students to learn word parts directly associated with a body system (or specialty area), and this has been the key to my approach in all of my texts and software products.

    The first topic considered is gladiatorial combat; not merely popular entertainment, it was also an important element in Roman politics. The book then investigates the composition of the political elite in the late Republic and Principate (249 BC - AD 235), showing that ideals of hereditary succession disguised high rates of social mobility. The final chapter ranges over aristocratic death rituals and tombs, funerals and ghost stories, to the search for immortality and the power of the Roman dead in distributing property by written wills.

    Also introduced are many new concepts for ultra-low emissions combustors, which rely on new advances in fuel preparation and liner wall-cooling techniques for their success.

    In 1952 the book was published by Princeton University Press in an English translation by the distinguished scholar of Chinese history, Derk Bodde, "the dedicated translator of Fung Yu-lan's huge history of Chinese philosophy" (New York Times Book Review). Available for the first time in paperback, it remains the most complete work on the subject in any language.Volume I covers the period of the philosophers, from the beginnings to around 100 B.C., a philosophical period as remarkable as that of ancient Greece. Volume II discusses a period lesser known in the West--the period of classical learning, from the second century B.C. to the twentieth century.

    Updated throughout, it covers the essential mathematics required by students of economics and business. The emphasis is on applying mathematics rather than providing theorems, and a wide range of applications are covered with detailed answers provided for many of the exercises.The book is structured, and the material deliberately selected, to increase in difficulty as the book progresses. Subjects covered include: algebra; linear equations, with immediate applications in simple economic models of markets and the national economy; natural generalizations of elementary matrix algebra and non-linear equations; applications in finance; the groundwork for calculus; profit maximization for a firm, simple inventory models, and other applications of marginal concepts; integration covering both standard analytical techniques and numerical methods; partial differentiation; linear programming; and dynamic relationships in continuous terms and in discrete terms. Three appendices provide extensive treatment of trigonometric functions, an introduction to set theory, and detailed answers to all exercises provided.

    It has overcome its continental isolation and has also established itself in the English-speaking world. By attracting both problem inquiry and problem-solving-oriented scientists with different cultural, academic, and profes- sional backgrounds from all over the world, it has broadened not only its geo- graphical but also its conceptual and methodological scopes. We are pleased to confirm in 1993 that the growth of landscape ecology continues, and to again express our gratification at the encouraging re- sponse to this first English-language monograph on the subject and its contribution to these developments. As before, we feel special satisfac- tion that it has reached not only the shelves of libraries and academic re- searchers, but that it has also appealed to professional practitioners, teachers, and their students from industrialized and developing countries, embracing the broad range of fields related to landscape ecology in the natural sciences as well as in the humanities.

    The author, well-known for presenting concepts and techniques in the most precise, accessible manner possible, introduces students to the fundamentals of engineering design through a highly visual format and numerous step-by-step examples and hands-on exercises. As a matter of fact, Engineering Design Graphics is one of the few texts available today that actually features illustrations drawn by its author.While retaining many of the features that have made previous editions so successful, the ninth edition incorporates a number of key revisions that help make it the most comprehensive, classically modern, and competitively-priced textbook on the market:Comprehensive Eight chapters cover the 6 complete design process-from preliminary ideas to implementation - including a full chapter containing design problemsIntegrates Computer Methods boxes throughout Includes Chapter 23: Working Drawings which can be used to create a variety of additional classroom assignments Incorporates civil engineering applications and specialty chapters on pipe drafting and electric/electronics drafting Classically Modern Features coverage of 3D methods and solid modeling, as well as complete coverage of traditional 2D drawing methods Updated coverage of AutoCAD(r) Release 14 (optional coverage of AutoCAD Release 13 is also available) Features a chapter on career options to get students thinking about the future Incorporates a second color throughout as a teaching and learning aid Step-by-step methods are outlined in figure captions - not buried in the text

    Much of this progress is represented in this revised, expanded edition, including such topics as the Feigenbaum universality of period doubling, the Zoladec solution, the Iljashenko proof, the Ecalle and Voronin theory, the Varchenko and Hovanski theorems, and the Neistadt theory. In the selection of material for this book, the author explains basic ideas and methods applicable to the study of differential equations. Special efforts were made to keep the basic ideas free from excessive technicalities. Thus the most fundamental questions are considered in great detail, while of the more special and difficult parts of the theory have the character of a survey. Consequently, the reader needs only a general mathematical knowledge to easily follow this text. It is directed to mathematicians, as well as all users of the theory of differential equations.

    The book centers around those properties that have to do with uniform convergence and uniform limits in the context of differentiation and integration. Topics discussed include the classical test for convergence of series, Fourier series, polynomial approximation, the Poisson kernel, the construction of harmonic functions on the disc, ordinary differential equation, curve integrals, derivatives in vector spaces, multiple integrals, and others. One of the author's main concerns is to achieve a balance between concrete examples and general theorems, augmented by a variety of interesting exercises. Some new material has been added in this second edition, for example: a new chapter on the global version of integration of locally integrable vector fields; a brief discussion of L1-Cauchy sequences, introducing students to the Lebesgue integral; more material on Dirac sequences and families, including a section on the heat kernel; a more systematic discussion of orders of magnitude; and a number of new exercises.

    A large number of empirically based relationships describe biological rates as simple functions of body size; and other such relations predict the intrinsic rate of population growth, animal speed, animal density, territory size, prey size, physiology, and morphology. Such equations almost always exist for mammals and birds, often for other vertebrates and invertebrates, sometimes for protozoa, algae, and bacteria, and occasionally even for plants. There are too many organisms to measure all aspects of the biology of every species of population, so scientists must depend on generalizations. Body size relations represent our most extensive and powerful assemblage of generalizations, but they have never been organized for use in ecology. This book represents the largest single compilation of interspecific size relations, and instructs the reader on the use of these relationships; their comparison, combination, and criticism. Both strengths and weaknesses of our current knowledge are discussed in order to indicate the many possible directions for further research. This important volume will therefore provide a point of departure toward a new applied ecology, giving quantitative solutions to real questions. It will interest advanced students of ecology and comparative physiology as well as professional biologists.
