Autoradiography is the localization within a solid specimen of a radiolabel by placing the specimen against a layer of detector material. Many types of specimen can be studied, from whole organisms to ultra-this cryosections. Indeed, rather than being a single technique, autoradiography is a collection of methods with certain features in common. Between them, these techniques can supply information at the macroscopic, microscopic, and ultrastructural levels, and their use is important to biological scientists in a variety of research areas. In this handbook, the author provides a comprehensive overview of the major techniques of autoradiography. With the aid of numerous illustrations, the various methods are clearly described, and the information which they can provide is discussed. Suggestions for further reading are provided at the end of most chapters. The student involved in biological or biomedical research will find this an invaluable introduction to the theory and techniques of autoradiography, and a clear guide to choosing the correct approach for his or her particular application. It will also be of interest to more experienced researchers, who are already familiar with one particular method, and wish to broaden their approach to another level.

Laboratory work is an essential part of undergraduate chemistry courses. The laboratory provides a setting for training not just in practical hand and instrument skills, but also for other skills such as planning, recording, interpreting and working in teams. However, students often learn little from their time in the laboratory and find it hard to make connections with lectures. Over half of third-level chemical students have no intention of becoming practising chemists anyway. Teaching staff may also feel pressured in relation to manpower, materials, time and safety. Carrying out exercises before and after laboratory sessions can maximise the benefit of practical work for higher education students. This books surveys existing materials for pre-laboratory and post-laboratory exercises in the chemical sciences. Twenty examples are given, and guidance is provided for constructing similar exercises.

The knowledge base of chromatography continued to expand throughout the 1990s owing to its many applications to problems of contemporary interest in industry, life and environmental sciences. Organizing this information into a single text for a diverse group of scientists has become increasingly difficult. The present book stemmed from the desire to revise Chromatography Today, written by the same author with Salwa K. Poole, and published in 1991. This title is considered to be one of the definitive texts on chromatography. It was soon realized however, that a simple revision would not provide the desired result of a contemporary picture of the practice of chromatography at the turn of the century. The only workable solution was to start afresh, maintaining the same general philosophy and concept for Chromatography Today where possible, while creating essentially a new book.
The format of the new book is modular, with extensive cross-references to permit rapid location of related material using different separation concepts. Important features are extensive tabulation of essential data for performing separations and an extensive bibliography to the most recent literature.
This title is intended as a suitable text for graduate level courses in the separation sciences and as a self-study guide for professional chromatographers wishing to refresh their background in this rapidly expanding field.
The Essence of Chromatography presents a comprehensive survey of modern chromatography and is an effective replacement for Chromatography Today.
.Comprehensive and authoritative coverage of chromatographic techniques
.Contains extensive coverage of recent literature on this subject
.Ideal text for graduates and suitable for professional chromatographers"

We may learn from our mistakes, but Deborah Mayo argues that, where experimental knowledge is concerned, we haven't begun to learn enough. "Error and the Growth of Experimental Knowledge" launches a vigorous critique of the subjective Bayesian view of statistical inference, and proposes Mayo's own error-statistical approach as a more robust framework for the epistemology of experiment. Mayo genuinely addresses the needs of researchers who work with statistical analysis, and simultaneously engages the basic philosophical problems of objectivity and rationality.
Mayo has long argued for an account of learning from error that goes far beyond detecting logical inconsistencies. In this book, she presents her complete program for how we learn about the world by being "shrewd inquisitors of error, white gloves off." Her tough, practical approach will be important to philosophers, historians, and sociologists of science, and will be welcomed by researchers in the physical, biological, and social sciences whose work depends upon statistical analysis.

We are now accustomed to conceive of science as an instrumental activity, producing numbers, measurements and graphs by means of sophisticated devices. This book investigates the historical process that gave rise to this instrumental culture. The contributors trace the displacement of instruments across the globe, the spread of practices or precision and the circulation and appropriation of skills and knowledge.
Through comparative and contextual approaches, the volume confronts the tension between the local and the global, examining the process of the universalization of science. Bringing together case studies ranging from the seventeenth to the twentieth centuries, contributors discuss French, German and British initiatives, as well as the knowledge and techniques of travellers in countries such as India, Africa, South East Asia and the Americas.
Students and researchers interested in the history of science in both Western and non-Western cultures will find this book a valuable and thought-provoking read.
