Archaeological chemistry / par Pollard,, A. Mark. Publication : [S.l.] : Royal Society of Chemistry, 1996 . 392 p. ; , The application of chemistry within archaeology is an important and fascinating area. It allows the archaeologist to answer such questions as "what is this artefact made of?", "where did it come from?" and "how has it been changed through burial in the ground?", providing pointers to the earliest history of mankind. Archaeological Chemistry begins with a brief description of the goals and history of archaeological science, and the place of chemistry within it. It sets out the most widely used analytical techniques in archaeology and compares them in the light of relevant applications. The book includes an analysis of several specific archaeological investigations in which chemistry has been employed in tracing the origins of or in preserving artefacts. The choice of these investigations conforms to themes based on analytical techniques, and includes chapters on obsidian, ceramics, glass, metals and resins. Finally, it suggests a future role for chemical and biochemical applications in archaeology. Archaeological Chemistry enables scientists to tackle the fundamental issues of chemical change in the archaeological materials, in order to advance the study of the past. It will prove an essential companion to students in archaeological science and chemistry, field and museum archaeologists, and all those involved in conserving human artefacts. 22 cm.

Career management for chemists / par Fetzer, John. Publication : [S.l.] : Springer, 2004 . 266 p. ; , Building a successful career in the sciences depends on more than good technical knowledge and research skills. Communication and interpersonal skills, as well as personal traits, are often decisive factors in the level of advancement and satisfaction that can be achieved. But where do scientists, from new graduates to mid-career professionals, go for insights and advice on how to plan, manage or reengineer their careers? Now John FetzerÆs. 24 cm.

Extraction of organic analytes from food : a manual of methods / par Self, R. Publication : [S.l.] : Royal Society of Chemistry, 2005 . 344 p. ; , This book is designed as a laboratory manual of methods used for the preparation and extraction of organic chemical compounds from food sources. It offers ideas on how to facilitate progress towards the total automation of the assay, as well as proposing assays for unknowns by comparison with known methods. Beginning with an introduction to extraction methodology, Extraction of Organic Analytes from Foods then progresses through sample preparation, extraction techniques (partition, solvation, distillation, adsorption and diffusion) and applications. Subject indices for the applications are organised by commodity, method, chemical class and analyte, and provide useful examples of references from the literature to illustrate historical development of the techniques. Examples of methods that have been compared, combined or used in collaborative trials have been correlated and used to form the beginnings of a database that can be expanded and updated to provide a laboratory reference source. Logically structured and with numerous examples, Extraction of Organic Analytes from Foods will be invaluable to practising food analysts as both a reference and training guide. In addition, the introductory sections in each chapter have been written with food science and technology students in mind, making this an important title for academic libraries. 24 cm.

International tables for crystallography, symmetry relations between space groups.   Publication : [S.l.] : Wiley, 2004 . 744 p. ; , This volume presents a systematic treatment of the maximal subgroups and minimal supergroups of the crystallographic plane groups and space groups. It is an extension of and a supplement to Volume A, Space-group symmetry, in which only basic data for sub- and supergroups are provided. Group-subgroup relations, apart from their theoretical interest, are the basis of a number of important applications in crystallographic research: (1) In solid-state phase transitions there often exists a group-subgroup relation between the symmetry groups of the two phases. According to Landau theory, this is in fact mandatory for displacive (continuous, second-order) phase transitions. Group-subgroup relations are also indispensable in cases where the symmetry groups of the two phases are not directly related but share a common subgroup or supergroup. (2) Group-subgroup relations provide a concise and powerful tool for revealing and elucidating relations between crystal structures. They can thus help to keep up with the ever-increasing amount of crystal-structure data. Their application requires knowledge of the relations of the Wyckoff positions of group-subgroup related structures. (3) Group-subgroup relations are of great importance in the study of twinned crystals, domain structures and domain boundaries. (4) These relations can even help to identify errors in space-group assignment and crystal-structure determination. (5) Subgroups of space groups provide a valuable approach to teaching crystallographic symmetry. Volume A1 consists of three parts: Part 1 presents an introduction to the theory of space groups at various levels and with many examples. It includes a chapter on the mathematical theory of subgroups. Part 2 gives for each plane group and space group a complete listing of all maximal subgroups and minimal supergroups. The treatment includes the generators of each subgroup as well as any necessary changes of the coordinate system. Maximal isomorphic subgroups are given in parameterized form as infinite series because of the infinite number for each group. A special feature of the presentation is graphs that illustrate the group-subgroup relations. Part 3 lists the relations between the Wyckoff positions of every space group and its subgroups. Again, the infinite number of maximal isomorphic subgroups of each space group are covered by parameterized series. These data for Wyckoff positions are presented here for the first time. Audience: The volume is a valuable addition to the library of scientists engaged in crystal-structure determination, crystal physics or crystal chemistry. It is essential for those interested in phase transitions, the systematic compilation of crystal structures, twinning phenomena and related fields of crystallographic research. 31 cm.
