The fourth edition of the TNM Classification was published in 1987,1 and a revision in 1992.2 It was the result of efforts by all national TNM Committees towards a worldwide uniform classification. The classifica tion criteria are identical with the fourth edition of the Manual for 3 Staging of Cancer of the American Joint Committee on Cancer (AJCC). Although the classification has found wide acceptance, some workers have pointed out that individual definitions and rules for staging are not sufficiently detailed. This can lead to inconsistent application of the clas sification. the antithesis of standardization. This source of differences in interpretation applies not only to the classification of individual organs but also to the general rules of the system, especially to the definitions of the requirements for the pathological classification (pT, pN). These are specified only for carcinoma of the breast; for other sites, reference must be made back to the general rules. which can lead to variable interpreta tions. The TNM Project Committee of the UICC has addressed this prob lem and collected and considered the criticisms and suggestions from the national TNM Committees as well as from cancer registries, oncolo gical associations and individual users. The result was the decision to complement the 4th edition of the TN M Classification 1.2. 3 with the publi cation of a TNM Supplement containing recommendations for the uni form use of TNM."

"The Elements"has become an international sensation, with over one million copies in-print worldwide.The highly-anticipated paperback edition of"The Elements"is finally available.An eye-opening, original collection of gorgeous, never-before-seen photographic representations of the 118 elements in the periodic table.The elements are what we, and everything around us, are made of. But how many elements has anyone actually seen in pure, uncombined form?"The Elements"provides this rare opportunity. Based on seven years of research and photography, the pictures in this book make up the most complete, and visually arresting, representation available to the naked eye of every atom in the universe. Organized in order of appearance on the periodic table, each element is represented by a spread that includes a stunning, full-page, full-color photograph that most closely represents it in its purest form. For example, at -183 C, oxygen turns from a colorless gas to a beautiful pale blue liquid.Also included are fascinating facts, figures, and stories of the elements as well as data on the properties of each, including atomic weight, density, melting and boiling point, valence, electronegativity, and the year and location in which it was discovered. Several additional photographs show each element in slightly altered forms or as used in various practical ways. The element's position on the periodic table is pinpointed on a mini rendering of the table and an illustrated scale of the element's boiling and/or melting points appears on each page along with a density scale that runs along the bottom.Packed with interesting information, this combination of solid science and stunning artistic photographs is the perfect gift book for every sentient creature in the universe.Includes a tear-out poster of Theodore Gray's iconic Photographic Periodic Table "

units have been included. References, which now number approximately 650, have been brought up to date. The most recently accepted values of the physical constants have been provided. Our thanks go to all those who, since the fifth edition, have helped in this revision by suggestions. In particular the authors express their gratitude to Jane M. Jerrard who, with enthusiasm, put the text into a computer and eliminated the editorial scissors and paste and simplified the onerous and long task of producing a text from the fragmented material of the revision. In the preface to the fifth edition it was suggested that the book provided at that time the most complete and up-to-date information of its kind available. The authors again make the same claim for this sixth edition. H. G. JERRARD D. B. McNEILL Warsash Newtownards Southampton Northern Ireland England Preface to the first edition The intense specialization that occurs in science today has meant that scientists working in one field are often not familiar with the nomenclature used by their colleagues in other fields. This is particularly so in physics. This dictionary is designed to help overcome this difficulty by giving information about the units, dimensionless numbers and scales which have been used, or are still being used, throughout the world. Some four hundred entries are provided and these are supplemented by about five hundred references. The definition of each entry is given together with relevant historical facts.

The Fifth Report of the International Committee on Taxonomy of Viruses (ICTV), summarizes the proceedings and decisions reached by the ICTV at its meetings held at the International Congresses of Virology in Sendai (1984), Edmonton (1987) and Berlin (1990). This report has been organized in the same way as the previous ones (Wildy, 1971; Fenner, 1976; Matthews, 1979; 1982), yet it encompasses many more families and groups of viruses than previous reports, and it includes new tables, diagrams and keys. The officers and members of the ICTV study groups from 1984 to 1990 are listed, as the current ICTV statutes and rules of nomenclature. Information on the format for submission of new taxonomic proposals to the ICTV is also provided. Since the Fourth Report of the ICTV (1982), 19 new virus families and groups have been described. This report includes 2,430 viruses belonging to 73 families or groups, as well as virus satellites and viroids descriptions, but it does not include descriptions not approved by the ICTV. It now will be possible to publish such preliminary, and in some cases controversial, descriptions in the Virology Division pages of the Archives of Virology --this will allow virologists to carry on the kind of interim dialogue that is necessary for arriving at broad agreement on taxonomic matters.

The "raison d'etre" of hierarchical dustering theory stems from one basic phe nomenon: This is the notorious non-transitivity of similarity relations. In spite of the fact that very often two objects may be quite similar to a third without being that similar to each other, one still wants to dassify objects according to their similarity. This should be achieved by grouping them into a hierarchy of non-overlapping dusters such that any two objects in ne duster appear to be more related to each other than they are to objects outside this duster. In everyday life, as well as in essentially every field of scientific investigation, there is an urge to reduce complexity by recognizing and establishing reasonable das sification schemes. Unfortunately, this is counterbalanced by the experience of seemingly unavoidable deadlocks caused by the existence of sequences of objects, each comparatively similar to the next, but the last rather different from the first."

The original suggestion to organize a symposium about the classi fication and evolution of the Flowering Plants was made at, the International Botanical Congress at Leningrad in 1975, and the idea was so well accepted by several colleagues that plans for such a symposium quickly took shape. An organizing committee consisting of Professor H. MERXMULLER, Miinchen, Professor V. H. HEYWOOD, Reading, and Professor K. KUBITZKI, Hamburg, was set up. The conference took place on 7-12 September 197tl in the Institut fiir Allgemeine Botanik of the University of Hamburg under the auspices of the International Association for Plant Taxonomy and was at tended by 80 participants from 14 countries. There have been several meetings in recent years which have dealt with the origin and evolution of the Flowering Plants so that it might be questioned whether yet another symposium dealing with more or less the same subject were really "justified. As the reader will see from the contents of the book, this symposium differed from similar ones held recently in two respects: 1. Emphasis was given to methodological aspects of the classification of higher taxa, and 2. much classificatory and evolutionary evidence relating to the higher taxa of Flowering Plants was presented."

Science communication is a rapidly expanding area and meaningful engagement between scientists and the public requires effective communication. Designed to help the novice scientist get started with science communication, this unique guide begins with a short history of science communication before discussing the design and delivery of an effective engagement event. Along with numerous case studies written by highly regarded international contributors, the book discusses how to approach face-to-face science communication and engagement activities with the public while providing tips to avoid potential pitfalls. This book has been written for scientists at all stages of their career, including undergraduates and postgraduates wishing to engage with effective science communication for the first time, or looking to develop their science communication portfolio.

People have been interested in knots at least since the time of Alexander the Great and his encounter with the Gordian knot. There are famous knot illustrations in the Book of Kells and throughout traditional Islamic art. Lord Kelvin believed that atoms were knots in the ether and he encouraged Tait to compile a talbe of knots about 100 years ago. In recent years, the Jones polynomial has stimulated much interest in possible relationships between knot theory and physics. The book is concerned with the fundamental question of the classification of knots, and more generally the classification of arbitrary (compact) topological objects which can occur in our normal space of physical reality. Professor Hemion explains his classification algorithm - using the method of normal surfaces - in a simple and concise way. The reader is thus shown the relevance of such traditional mathematical objects as the Klein bottle or the hyperbolic plane to this basic classification theory. The Classification of Knots and 3-dimensional Spaces will be of interest to mathematicians, physicists, and other scientists who want to apply this basic classification algorithm to their research in knot theory.

The notion of 'natural kinds' has been central to contemporary discussions of metaphysics and philosophy of science. Although explicitly articulated by nineteenth-century philosophers like Mill, Whewell and Venn, it has a much older history dating back to Plato and Aristotle. In recent years, essentialism has been the dominant account of natural kinds among philosophers, but the essentialist view has encountered resistance, especially among naturalist metaphysicians and philosophers of science. Informed by detailed examination of classification in the natural and social sciences, this book argues against essentialism and for a naturalist account of natural kinds. By looking at case studies drawn from diverse scientific disciplines, from fluid mechanics to virology and polymer science to psychiatry, the author argues that natural kinds are nodes in causal networks. On the basis of this account, he maintains that there can be natural kinds in the social sciences as well as the natural sciences.

Biologist Carol Kaesuk Yoon explores the historical tension between evolutionary biology and taxonomy. Carl Linnaeus struggled in the eighteenth century to define species in light of their mutability while still relying on intuitive, visual judgments. As taxonomy modernized, it moved into labs, yielding results counterintuitive to humanity s innate predisposition to order the world. By conceding scientific authority to taxonomists, Yoon argues, we ve contributed to our own alienation from nature."

The first volume, which runs well over 1,000 pages, contains the classification at the three- and four-character levels, the classification of the morphology of neoplasms, special tabulation lists for mortality and morbidity, definitions, and the nomenclature regulations. The volume also reproduces the report of the International Conference for the Tenth Revision, which indicates the many complex considerations behind the revisions.

Chemical nomenclature is used to identify a chemical species by means of written or spoken words and enables a common language for communication amongst chemists. Nomenclature for chemical compounds additionally contains an explicit or implied relationship to the structure of the compound, in order that the reader or listener can deduce the structure from the name. This purpose requires a system of principles and rules, the application of which gives rise to a systematic nomenclature. Of course, a wide range of traditional names, semisystematic or trivial, are also in use for a core group of common compounds. Detailing the latest rules and international practice, this new volume can be considered a guide to the essential organic chemical nomenclature, commonly described as the "Blue Book". An invaluable source of information for organic chemists everywhere and the definitive guide for scientists working in academia or industry, for scientific publishers of books, journals and databases, and for organisations requiring internationally approved nomenclature in a legal or regulatory environment.

Embracing more than 5,000 genera, distributed in 425 families and 46 orders, Malcolm C. McKenna and Susan K. Bell's "Classification of Mammals" is the most comprehensive work to date on the systematics, relationships, and occurrences of all mammal taxa, living and extinct, down through the rank of genus.

Since George Gaylord Simpson's 1945 classification, the paleontological record has been recalibrated, and the intervening years have seen much debate and progress concerning the theoretical underpinnings of systematization. McKenna inherited the project from Simpson and, with Bell, has constructed a completely updated hierarchical system that reflects the genealogy of Mammalia.

Covering a range of metaphors from a diverse field of sciences, from cell and molecular biology to evolution, ecology, and biomedicine, Understanding Metaphors in the Life Sciences explores the positive and negative implications of the widespread use of metaphors in the biological and life sciences. From genetic codes, programs, and blueprints, to cell factories, survival of the fittest, the tree of life, selfish genes, and ecological niches, to genome editing with CRISPR's molecular scissors, metaphors are ubiquitous and vital components of the modern life sciences. But how exactly do metaphors help scientists to understand the objects they study? How can they mislead both scientists and laypeople alike? And what should we all understand about the implications of science's reliance on metaphorical speech and thought for objective knowledge and adequate public policy informed by science? This book will literally help you to better understand the metaphorical dimensions of science.

This new edition of a foundational text presents a contemporary review of cladistics, as applied to biological classification. It provides a comprehensive account of the past fifty years of discussion on the relationship between classification, phylogeny and evolution. It covers cladistics in the era of molecular data, detailing new advances and ideas that have emerged over the last twenty-five years. Written in an accessible style by internationally renowned authors in the field, readers are straightforwardly guided through fundamental principles and terminology. Simple worked examples and easy-to-understand diagrams also help readers navigate complex problems that have perplexed scientists for centuries. This practical guide is an essential addition for advanced undergraduates, postgraduates and researchers in taxonomy, systematics, comparative biology, evolutionary biology and molecular biology.

The first IUPAC Manual of Symbols and Terminology for Physicochemical Quantities and Units was published in 1969 with the objective of 'securing clarity and precision, and wider agreement in the use of symbols, by chemists in different countries, among physicists, chemists and engineers, and by editors of scientific journals'. Subsequent revisions have taken account of many developments in the field and were also substantially expanded and improved in presentation in several new editions of what is now widely known as the ‘Green Book of IUPAC’. This abridged version of the forthcoming 4th edition reflects the experience of the contributors and users of the previous editions. The book has been systematically brought up to date and provides a compilation of generally used terms and symbols with brief, understandable definitions and explanations. Tables of important fundamental constants and conversion factors are included. In this abridged guide, the more specialized and complex material has been omitted, retaining, however, the essence of the Green Book. It is particularly intended to be suitable for students and teachers but it should also be useful for scientists, science publishers and organizations working across a multitude of disciplines requiring internationally approved terminology in the area of Physical Chemistry. It now includes the most up to date definitions and constants in agreement with the ‘new SI’ as established by agreement on the International System of Units in Paris in 2019. It should find the widest possible acceptance and use for best practice in science and technology.

This text can be read at many levels. Not least it is an extraordinary inventory - an illustrated summary of all the Earthly creatures that have ever lived. Whatever living thing you come across, from E-coli to an oak tree or an elephant, this book will show you what kind of creature it is, and how it relates to all others. Yet there are far too many creatures to present merely as a catalogue. The list of species already described is vast enough - nearly two million - but there could in reality be as many as 30 million different animals, plants, fungi and protists - and perhaps another 400 million different bacteria and archaea. In the 4000 million years or so since life first began on Earth, there could have been several thousand billion different species. The only way to keep track of so many is to classify - placing similar creatures into categories, which nest within larger categories, and so on. As the centuries have passed, so it has become clear that the different groups are far more diverse than had ever been appreciated. Thus Linneus in the 18th century placed all living things in just two kingdoms, Animals and Plants.

The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) addresses classification and labelling of chemicals by types of hazards. It provides the basis for worldwide harmonization of rules and regulations on chemicals and aims at enhancing the protection of human health and the environment during their handling, transport and use by ensuring that the information about their physical, health and environmental hazards is available. The sixth revised edition includes, inter alia, a new hazard class for desensitized explosives and a new hazard category for pyrophoric gases; miscellaneous amendments intended to further clarify the criteria for some hazard classes (explosives, specific target organ toxicity following single exposure, aspiration hazard, and hazardous to the aquatic environment) and to complement the information to be included in section 9 of the Safety Data Sheet; revised and further rationalized precautionary statements; and an example of labelling of a small packaging in Annex 7.

How do you describe an analytical method, measure the purity of the new chemical that you have just synthesized, or report the proper units of measurement? For analytical chemists, the principal tool of the trade, or source of terms, is this book - the so-called Orange Book. First published in 1978, this latest edition takes into account the explosion of new analytical procedures and, at the same time, the diversity of techniques and the quality and performance characteristics of the procedures that are the focus of interest. The scope of analytical chemistry has widened, new types of instrumental techniques have emerged and automation has taken over. Answers can now be shared, not only on the chemical composition and structure of the sample, but also changes in composition and structure in space and time. New chapters on chemometrics, bio-analytical methods of analysis, and sample treatment and preparation have been added. The terminology of metrology and quality assurance is now up to date with the latest ISO and JCGM standards. This new volume will be an indispensable reference resource for the coming decade, revising and updating accepted terminology, and providing the official language of analytical chemistry.

This second part of Volume 48 of the Flora of Pan-Himalaya is devoted to the single genus, Saussurea of the Asteraceae family, which has wide medicinal applications. This is the largest family in the Pan-Himalaya, with 235 species, 149 of which are endemic to the Pan-Himalaya. Saussurea is a notoriously difficult, largely Asiatic, genus with often indistinct species boundaries. Many new species of Saussurea were described in the course of preparing this account. The nomenclatural novelties in this volume include five changes in status, and 17 new synonyms. 27 lectotypes are newly designated. During the research for this volume, the author and his team described 40 new species of Saussurea, and these, along with numerous new designations and classifications, are recorded here for the first time.

This popular safety best-seller is designed to help the user quantify the expected damage of potential fire and explosion incidents in realistic terms, identify the equipment likely to contribute to the creation or escalation of an incident, and communicate the fire and explosion risk potential to management. Based on Dow's Fire and Explosion Risk Analysis Program, the index provides a step-by-step, objective evaluation of the actual fire and explosion, as well as reactivity potential of process equipment and its contents.

"To my knowledge, there has never [before] been a volume that analyzes, in one place, the actual language of science-- those elements of thinking that are acknowledged to be the basis of scientific thought. . . . [Thus] this is a very important book, contributing to several fields: science, education, rhetoric, medicine, and perhaps even philosophy. . . . Darian's erudition is truly astonishing." -- Celest A. Martin, Associate Professor, College Writing Program, University of Rhode Island

From astronomy to zoology, the practice of science proceeds from scientific ways of thinking. These patterns of thought, such as defining and classifying, hypothesizing and experimenting, form the building blocks of all scientific endeavor. Understanding how they work is therefore an essential foundation for everyone involved in scientific study or teaching, from elementary school students to classroom teachers and professional scientists.

In this book, Steven Darian examines the language of science in order to analyze the patterns of thinking that underlie scientific endeavor. He draws examples from university science textbooks in a variety of disciplines, since these offer a common, even canonical, language for scientific expression. Darian identifies and focuses in depth on nine patterns-- defining, classifying, using figurative language, determining cause and effect, hypothesizing, experimenting, visualizing, quantifying, and comparing-- and shows how they interact in practice. He also traces how these thought modes developed historically from Pythagoras through Newton.

From subarctic tundra to equatorial rainforest, deep in the soil and at the tip of the highest tree, ants are found the world over. This book, by the world's leading ant taxonomist, offers a definitive guide for identifying these ubiquitous insects.

Barry Bolton provides identification keys to all the living ant subfamilies and genera, presented in alphabetical order and separated by zoogeographical region. Designed for professional and amateur myrmecologists alike, this guide is as accessible as it is comprehensive, including information on the function and use of identification keys, instructions for preparing specimens for examination, and an illustrated glossary of morphological terms. Over 500 scanning electron microscope photographs illustrate the taxonomic keys.

Bolton introduces each subfamily with a diagnosis of the group, followed by synoptic classifications of all genera within each subfamily, notes on broad distribution, and a list of references to all species-rank publications useful to identification. He also provides a short summary of the extinct subfamilies and includes a checklist of every name ever proposed in the classification of ants, from the rank of family down to subgenus, showing the current status and usage of each.

An updated and exhaustively expanded revision of the taxonomic keys found in Hö lldobler and Wilson's "The Ants," Bolton's identification guide takes its place alongside that landmark work as the foundation for the study of ants for many years to come.
