Analytical electron microscopy is one of the most powerful tools today for characterization of the advanced materials that support the nanotechnology of the twenty-first century. In this book the authors clearly explain both the basic principles and the latest developments in the field. In addition to a fundamental description of the inelastic scattering process, an explanation of the constituent hardware is provided. Standard quantitative analytical techniques employing electron energy-loss spectroscopy and energy-dispersive X-ray spectroscopy are also explained, along with elemental mapping techniques. Included are sections on convergent beam electron diffraction and electron holography utilizing the field emission gun. With generous use of illustrations and experimental data, this book is a valuable resource for anyone concerned with materials characterization, electron microscopy, materials science, crystallography, and instrumentation.

Ecological Methods by the late T.R. E. Southwood and revised over the years by P. A. Henderson has developed into a classic reference work for the field biologist. It provides a handbook of ecological methods and analytical techniques pertinent to the study of animals, with an emphasis on non-microscopic animals in both terrestrial and aquatic environments. It remains unique in the breadth of the methods presented and in the depth of the literature cited, stretching right back to the earliest days of ecological research. The universal availability of R as an open source package has radically changed the way ecologists analyse their data. In response, Southwood's classic text has been thoroughly revised to be more relevant and useful to a new generation of ecologists, making the vast resource of R packages more readily available to the wider ecological community. By focusing on the use of R for data analysis, supported by worked examples, the book is now more accessible than previous editions to students requiring support and ideas for their projects. Southwood's Ecological Methods provides a crucial resource for both graduate students and research scientists in applied ecology, wildlife ecology, fisheries, agriculture, conservation biology, and habitat ecology. It will also be useful to the many professional ecologists, wildlife biologists, conservation biologists and practitioners requiring an authoritative overview of ecological methodology.

Particle characterization is an important component in product research and development, manufacture, and quality control of particulate materials and an important tool in the frontier of sciences, such as in biotechnology and nanotechnology. This book systematically describes one major branch of modern particle characterization technology - the light scattering methods. This is the first monograph in particle science and technology covering the principles, instrumentation, data interpretation, applications, and latest experimental development in laser diffraction, optical particle counting, photon correlation spectroscopy, and electrophoretic light scattering. In addition, a summary of all major particle sizing and other characterization methods, basic statistics and sample preparation techniques used in particle characterization, as well as almost 500 latest references are provided. The book is a must for industrial users of light scattering techniques characterizing a variety of particulate systems and for undergraduate or graduate students who want to learn how to use light scattering to study particular materials, in chemical engineering, material sciences, physical chemistry and other related fields.

Since antibodies tagged with markers have been developed, immunocytochemistry has become the method of choice for identifying tissue substances or for the localisation of nucleic acid in tissue by in situ hybridisation. Resin-embedded tissue is routinely used and new techniques are constantly introduced. Thus, the novice entering these fields has a breathtaking variety of methods open to him. This labmanual covers the embedding of tissue using epoxy resin methods to the more sensitive procedures employing the acrylics. The possibilities and results are discussed so that an understanding of the techniques can be acquired and appropriate choices made. The various resins available and all steps involved in tissue processing, beginning with fixation, as well as the great variety of labelling methods and markers that are commonly used for "on-section" cytochemistry and immunocytochemistry are described, including detailed protocols for the application.

Offers a comprehensive nonmathematical treatment regarding the design and analysis of experiments, focusing on basic concepts rather than calculation of technical details. Much of the discussion is in terms of examples drawn from numerous fields of applications. Subjects include the justification and practical difficulties of randomization, various factors occurring in factorial experiments, selecting the size of an experiments, different purposes for which observations may be made and much more.

Drawing on state-of-the-art cellular and molecular techniques as well as new and sophisticated imaging and information technologies, this comprehensive, three-volume collection of cutting-edge protocols provides readily reproducible methods for studying and analyzing the events of embryonic development. volume 1 (ISBN: 089603-574-3) contains techniques for establishing and characterizing several widely used experimental model systems, for the study of developmental patterns and morphogenesis, and for the examination of embryo structure and function. There are also step-by-step methods for the analaysis of cell lineage, the production and use of chimeras, and the experimental and molecular manipulation of embryos, including the application of viral vectors. volume 2 (ISBN: 0-89603-575-1) describes state-of-the-art methods for the study of organogenesis, the analysis of abnormal development and teratology, the screening and mapping of novel genes and mutations, and the application of transgenesis, including the production of transgenic animals and gene knockouts. No less innovative, volume 3 (ISBN: 0-89603-576-X) introduces powerful techniques for the manipulation of developmental gene expression and function, the analysis of gene expression, the characterization of tissue morphogenesis and development, the in vitro study of differentiation and development, and the genetic analysis of developmental models of diseases. Highly practical and richly annotated, the three volumes of Developmental Biology Protocols describe multiple experimental systems and details techniques adopted from the broadest array of biomedical disciplines.

Multivariate Calibration Harald Martens, Chemist, Norwegian Food Research Institute, Aas, Norway and Norwegian Computing Center, Oslo, Norway Tormod NA]s, Statistician, Norwegian Food Research Institute, Aas, Norway The aim of this inter-disciplinary book is to present an up-to-date view of multivariate calibration of analytical instruments, for use in research, development and routine laboratory and process operation. The book is intended to show practitioners in chemistry and technology how to extract the quantitative and understandable information embedded in non-selective, overwhelming and apparently useless measurements by multivariate data analysis. Multivariate calibration is the process of learning how to combine data from several channels, in order to overcome selectivity problems, gain new insight and allow automatic outlier detection. Multivariate calibration is the basis for the present success of high-speed Near-Infrared (NIR) diffuse spectroscopy of intact samples. But the technique is very general: it has shown similar advantages in, for instance, UV, Vis, and IR spectrophotometry, (transmittance, reflectance and fluorescence), for x-ray diffraction, NMR, MS, thermal analysis, chromatography (GC, HPLC) and for electrophoresis and image analysis (tomography, microscopy), as well as other techniques. The book is written at two levels: the main level is structured as a tutorial on the practical use of multivariate calibration techniques. It is intended for university courses and self-study for chemists and technologists, giving one complete and versatile approach, based mainly on data compression methodology in self-modelling PLS regression, with considerations ofexperimental design, data pre-processing and model validation. A second, more methodological, level is intended for statisticians and specialists in chemometrics. It compares several alternative calibration methods, validation approaches and ways to optimize the models. The book also outlines some cognitive changes needed in analytical chemistry, and suggests ways to overcome some communication problems between statistics and chemistry and technology.

This text is intended to provide students with instruction and valuable laboratory experience in the often neglected area of inorganic chemistry. Divided into four main parts, the book covers chemistry of the main group elements, chemistry of the transition metals, organometallic chemistry, and bioinorganic chemistry. Recognizing the high cost of materials, difficulties in waste disposal, and dangers of toxicity, the authors have adopted a ``microscale'' approach to experiments in the book, thereby also reducing the time students spend in preparation. With over 45 experiments, Microscale Inorganic Chemistry incorporates the use of a broad sampling of elements and also covers such topics as laboratory safety, equipment, report writing, and literature searching.

Since the creation of the term "Scientific Computing" and of its German counterpart "Wissenschaftliches Rechnen" (whoever has to be blamed for that), scientists from outside the field have been confused about the some what strange distinction between scientific and non-scientific computations. And the insiders, i. e. those who are, at least, convinced of always comput ing in a very scientific way, are far from being happy with this summary of their daily work, even if further characterizations like "High Performance" or "Engineering" try to make things clearer - usually with very modest suc cess, however. Moreover, to increase the unfortunate confusion of terms, who knows the differences between "Computational Science and Engineering" , as indicated in the title of the series these proceedings were given the honour to be published in, and "Scientific and Engineering Computing", as chosen for the title of our book? Actually, though the protagonists of scientific com puting persist in its independence as a scientific discipline (and rightly so, of course), the ideas behind the term diverge wildly. Consequently, the variety of answers one can get to the question "What is scientific computing?" is really impressive and ranges from the (serious) "nothing else but numerical analysis" up to the more mocking "consuming as much CPU-time as possible on the most powerful number crunchers accessible" .

Since the pioneering work of U. S. VonEuler, G. O. Burr, B. Samuelsson, and others in the field of eicosanoids, research in this area continues to grow rapidly. Novel eicosanoids are being discovered even as enzymes that ca- lyze the synthesis of well-established eicosanoids are being critically studied with respect to their regulation and function. The novice in this field will most likely encounter three areas of intense research activity: regulation of expression and function of enzymes, i.e., ph- pholipases, cyclooxygenases, and lipoxygenases involved in the syntheses of established eicosanoids, characterization and distribution in tissues of eicosanoid receptors, and discovery and biologic roles of novel eicosanoids. This book is a compilation of chapters addressing these three areas. Most chapters of Eicosanoid Protocols address the first area, giving p- ticular emphasis to the cyclooxygenases and their two isoforms. This was done intentionally, because the discovery of the constitutive and inducible isoforms of this enzyme have introduced new concepts in the pathobiology of inflammation and in the use of nonsteroidal anti-inflammatory drugs. Although receptors of most established eicosanoids have been characterized and cloned, only one chapter (on the thromboxane A receptor) was devoted to this area.

For students, DIY hobbyists, and science buffs, who can no longer get real chemistry sets, this one-of-a-kind guide explains how to set up and use a home chemistry lab, with step-by-step instructions for conducting experiments in basic chemistry - not just to make pretty colors and stinky smells, but to learn how to do real lab work: purify alcohol by distillation; produce hydrogen and oxygen gas by electrolysis; smelt metallic copper from copper ore you make yourself; analyze the makeup of seawater, bone, and other common substances; synthesize oil of wintergreen from aspirin and rayon fiber from paper; perform forensics tests for fingerprints, blood, drugs, and poisons; and much more.From the 1930s through the 1970s, chemistry sets were among the most popular Christmas gifts, selling in the millions. But two decades ago, real chemistry sets began to disappear as manufacturers and retailers became concerned about liability. "The Illustrated Guide to Home Chemistry Experiments" steps up to the plate with lessons on how to equip your home chemistry lab, master laboratory skills, and work safely in your lab.The bulk of this book consists of 17 hands-on chapters that include multiple laboratory sessions on the following topics: Separating Mixtures; Solubility and Solutions; Colligative Properties of Solutions; Introduction to Chemical Reactions and Stoichiometry; Reduction-Oxidation (Redox) Reactions; Acid-Base Chemistry; Chemical Kinetics; Chemical Equilibrium and Le Chatelier's Principle; Gas Chemistry; Thermochemistry and Calorimetry; Electrochemistry; Photochemistry; Colloids and Suspensions; Qualitative Analysis; Quantitative Analysis; Synthesis of Useful Compounds; and Forensic Chemistry. With plenty of full-color illustrations and photos, Illustrated Guide to Home Chemistry Experiments offers introductory level sessions suitable for a middle school or first-year high school chemistry laboratory course, and more advanced sessions suitable for students who intend to take the College Board Advanced Placement (AP) Chemistry exam. A student who completes all of the laboratories in this book will have done the equivalent of two full years of high school chemistry lab work or a first-year college general chemistry laboratory course. This hands-on introduction to real chemistry - using real equipment, real chemicals, and real quantitative experiments - is ideal for the many thousands of young people and adults who want to experience the magic of chemistry.

This companion to The New Statistical Analysis of Data by Anderson and Finn provides a hands-on guide to data analysis using SPSS. Included with this guide are instructions for obtaining the data sets to be analysed via the World Wide Web. First, the authors provide a brief review of using SPSS, and then, corresponding to the organisation of The New Statistical Analysis of Data, readers participate in analysing many of the data sets discussed in the book. In so doing, students both learn how to conduct reasonably sophisticated statistical analyses using SPSS whilst at the same time gaining an insight into the nature and purpose of statistical investigation.

Separation Methods in Drug Synthesis and Purification, Second Edition, Volume Eight, provides an updated on the analytical techniques used in drug synthesis and purification. Unlike other books on either separation science or drug synthesis, this volume combines the two to explain the basic principles and comparisons of each separation technique. New sections to this volume include enantiomer separation using capillary electrophoresis (CE) and capillary electro- chromatography, the computer simulation of chromatographic separation for accelerating method development, the application of chromatography and capillary electrophoresis used as surrogates for biological processes, and new developments in the established techniques of chromatography and preparative methods.

Since their rapid proliferation in the late 1960s and early 1970s, quadrupole mass spectrometers have had a profound impact across the physical sciences. Geometrically simple, yet behaviorally complex, these dynamic mass analyzers continue to facilitate remarkable breakthroughs in fields ranging from biochemical analysis to process control technology. Long regarded as the standard introduction to the field, Quadrupole Mass Spectrometry and Its Applications provides today's engineers and scientists with an authoritative, wide-ranging overview of the development and uses of quadrupoles. Beginning with the basic operating principles of quadrupole devices, the book moves from general explanations of the actions of radio-frequency fields to descriptions of their utilization in quadrupole mass filters, monopoles, three-dimensional quadrupole ion traps, and various time-of-flight spectrometers. A concluding series of chapters examines early applications of quadrupoles in atomic physics, gas chromatography, upper atmospheric research, medicine, and environmental studies. Superb writing from the field's foremost scientists along with the continued central role of quadrupoles in contemporary research make this volume as timely and relevant as ever.

Scanning Tunneling Microscopy III provides a unique introduction to the theoretical foundations of scanning tunneling microscopy and related scanning probe methods. The different theoretical concepts developed in the past are outlined, and the implications of the theoretical results for the interpretation of experimental data are discussed in detail. Therefore, this book serves as a most useful guide for experimentalists as well as for theoreticians working in the field of local probe methods.
In this second edition the text has been updated and new methods are discussed.

ism (i. e. , Saccharomyces carlsbergensis, or brewer's yeast) and one of its corresponding enzymes. The experiments on this organism and enzyme are not limited to the materials suggested and can be easily adapted to the desired technical level and available budget. Similarly, the subse- quent cloning experiments suggest that use of particular vectors and strains, but, as indicated, alternative materials can be used to success- fully perform the laboratory exercises.

The intent of this work is to bring together in a single volume the techniques that are most widely used in the study of protein stability and protein folding. Over the last decade our understanding of how p- teins fold and what makes the folded conformation stable has advanced rapidly. The development of recombinant DNA techniques has made possible the production of large quantities of virtually any protein, as well as the production of proteins with altered amino acid sequence. Improvements in instrumentation, and the development and refinement of new techniques for studying these recombinant proteins, has been central to the progress made in this field. To give the reader adequate background information about the s- ject, the first two chapters of this book review two different, yet related, aspects of protein stability. The first chapter presents a review of our current understanding of the forces involved in determining the conf- mational stability of proteins as well as their three-dimensional folds. The second chapter deals with the chemical stability of proteins and the pathways by which their covalent structure can degrade. The remainder of the book is devoted to techniques used in the study of these two major areas of protein stability, as well as several areas of active research. Although some techniques, such as X-ray crystallography and mass spectroscopy, are used in the study of protein stability, they are beyond the scope of this book and will not be covered extensively.

Since the first edition of "Scanning 'funneling Microscopy I" has been pub lished, considerable progress has been made in the application of STM to the various classes of materials treated in this volume, most notably in the field of adsorbates and molecular systems. An update of the most recent develop ments will be given in an additional Chapter 9. The editors would like to thank all the contributors who have supplied up dating material, and those who have provided us with suggestions for further improvements. We also thank Springer-Verlag for the decision to publish this second edition in paperback, thereby making this book affordable for an even wider circle of readers. Hamburg, July 1994 R. Wiesendanger Preface to the First Edition Since its invention in 1981 by G. Binnig, H. Rohrer and coworkers at the IBM Zurich Research Laboratory, scanning tunneling microscopy (STM) has devel oped into an invaluable surface analytical technique allowing the investigation of real-space surface structures at the atomic level. The conceptual simplicity of the STM technique is startling: bringing a sharp needle to within a few Angstroms of the surface of a conducting sample and using the tunneling cur rent, which flows on application of a bias voltage, to sense the atomic and elec tronic surface structure with atomic resolution Prior to 1981 considerable scepticism existed as to the practicability of this approach."

Scanning Tunneling Microscopy II, like its predecessor, presents detailed and comprehensive accounts of the basic principles and the broad range of applications of STM and related scanning probe techniques. The applications discussed in this volume come predominantly from the fields of electrochemistry and biology. In contrast to those in STM I, these studies may be performed in air and in liquids. The extensions of the basic technique to map other interactions are described in chapters on scanning force microscopy, magnetic force microscopy, and scanning near-field optical microscopy, together with a survey of other related techniques. Also discussed here is the use of a scanning proximal probe for surface modification. Together, the two volumes give a comprehensive account of experimental aspects of STM and provide essential reading and reference material. In this second edition the text has been updated and new methods are discussed.

It is now twenty years since Cohen and Boyer's first steps into DNA cloning. In the time since then, there has been an ever increasing acc- eration in the development and application of the cloning methodology. With the recent development of the polymerase chain reaction, a second generation of the technology has been born, enabling the isolation of DNA (and in particular, genes) with little more information than the p- tial knowledge of the sequence. In fact, DNA sequencing is now so advanced that it can almost be carried out on the industrial scale. As a consequence of these advances, it now appears feasible to sequence whole genomes, including one the size of the human. What are we going to do with this information? The future of basic molecular biology must lie in the ability to analyze DNA (and especially the genes within it) starting at the DNA level. It is for these problems that Protocols for Gene Analysis attempts to offer solutions. So you have a piece of DNA, possibly a gene--what do you do next? The first section of this book contains a number of "basic" te- niques that are required for further manipulation of the DNA. This s- tion is not intended to be a comprehensive collection of methods, but merely to serve as an up-to-date set of techniques. I refer you to other volumes in the Methods Molecular Biology series for further rec- binant DNA techniques.

Peptide synthesis has emerged as one of the most powerful tools in biochemical, pharmacological, immunological, and biophysical la- ratories. Recent improvements include general solid-phase method- ogy, new protecting groups, and automated equipment. These advances have allowed the facile synthesis of increasingly more complex p- tides. Many of these new and improved methods for the synthesis of peptides and peptide-related substances have been reported in various publications, but never compiled in a convenient handbook. Like other volumes in this series, Peptide Synthesis Protocols concentrates on the practical aspects of these procedures, providing the researcher with detailed descriptions and helpful tips about potential problems. This volume is not intended to serve as a basic guide to standard Merrifie- type solid-phase strategy, but rather to provide the researcher with some of the most recent applications in the field of peptide science. A c- panion volume, Peptide Analysis Protocols, will detail methodology for the charaterization of new synthetic peptides. Development of new methods and applications has continued actively even as this volume was in preparation. Owing to the number of contributors to this volume, it was necessary to establish a cutoff for publication purposes. We feel that all of the protocols presented are timely and up-to-date. Several promising new strategies, such as allyloxycarbonyl-based syntheses, were being developed at the time this volume was in the editing stages and will be included in future editions.

This monograph presents the still young, but already large and very active interdisciplinary realm of computer supported cooperative work (CSCW) in a systematic and well-balanced way. Besides technical progress also the cultural, social, legal, psychological and economic aspects of CSCW are discussed. The book makes accessible a wealth of information and culminates in the development and detailed discussion of a "Collaboratory" suitable to fulfil the needs of scientific cooperation in Europe.
The book addresses CSCW research and development professionals as well as the general scientist interested in CSCW-based scientific cooperation. The bibliography with its more than 600 entries and the subject index are particularly comprehensive and helpful.

This is the second of three volumes of Methods in Molecular Biology that deal with Physical Methods of Analysis. The first of these, Spectroscopic Methods and Analyses dealt with NMR spec troscopy, mass spectrometry, and metalloprotein techniques, and the third will cover X-ray crystallographic methods. As with the first volume. Microscopy, Optical Spectroscopy, and Macroscopic Techniques is intended to provide a basic understand ing for the biochemist or biologist who needs to collaborate with spe cialists in applying the techniques of modern physical chemistry to biological macromolecules. The methods treated in this book fall into four groups. Part One covers microscopy, which aims to visualize individual molecules or complexes of several molecules. Electron microscopy is the more familiar of these, while scanning tunneling microscopy is a new and rapidly developing tool. Methods for determining the shapes and sizes of molecules in solution are described in Part Two, which includes chapters on X-ray and neutron scattering, light scattering, and ult- centrifugation. Calorimetry, described in Part Three, provides the means to monitor processes involving thermodynamic changes, whether these are intramolecular, such as conformational transition, or the interactions between solutes or between a solute and its sol vent. Part Four is concerned with optical and infrared spectroscopy and describes applications ranging from the measurement of protein concentration by UV absorbance to the analysis of secondary struc ture using circular dichroism and Fourier-transform infrared spec troscopy."
