A Guide to Close Binary Systems (ISSN)
by Edwin Budding Osman DemircanIntroduction to Close Binary Systems provides a comprehensive survey and guide to the fast-moving field of multiple, specifically binary, stars, with an up to date account of research around 'close', i.e. interacting pairs. Such interactions allow direct quantification of stellar properties, opening up factual insights into basic building blocks of the Universe.The book provides a much needed update for the seminal Close Binary Systems of Zdenĕk Kopal. Following a comparable plan, it presents relevant subject matter with an emphasis on building a framework of understanding to serve as a supporting resource for students and researchers. The text starts from a general historical background and progresses into the main theoretical ideas supporting our prima facie interpretation of observations. The central chapters explore further into these observational methods, arranged according to the classic subdivisions of astrometry, spectroscopy and photometry. Optimal inversion of observational data into model parametrization is a theme through these chapters. Significant here is the problem of how non-uniqueness in modelling affects interpretation. The underlying issues of stellar evolution bearing on observational evidence become paramount in the last four chapters. The book proceeds step-by-step from directly understandable examples of unevolved pairs to the challenging cases where stars are found in more and more extreme conditions, leading up to the mergers of massive black hole pairs seen in the new field of gravitational wave astronomy. This is a valuable reference for postgraduate and advanced undergraduate students working in mainstream areas of stellar astrophysics, with applications also to exoplanet research which shares some methodological features. Course designers for stellar astrophysics will find a useful selection of topics within this book.Key features:• Provides a well-explained and backgrounded, up-to-date account of close binary systems, in a fast-moving field of research that is growing in scientific importance• Surveys a wide range of case-studies within the context of binary and multiple star systems• Fills an acknowledged gap in current literatureCover Image: A public memorial to Zdenek Kopal in his home town (birthplace) of Litomysl in Czechia.
A Guide to Empirical Orthogonal Functions for Climate Data Analysis
by Valeria Simoncini Antonio NavarraClimatology and meteorology have basically been a descriptive science until it became possible to use numerical models, but it is crucial to the success of the strategy that the model must be a good representation of the real climate system of the Earth. Models are required to reproduce not only the mean properties of climate, but also its variability and the strong spatial relations between climate variability in geographically diverse regions. Quantitative techniques were developed to explore the climate variability and its relations between different geographical locations. Methods were borrowed from descriptive statistics, where they were developed to analyze variance of related observations-variable pairs, or to identify unknown relations between variables. A Guide to Empirical Orthogonal Functions for Climate Data Analysis uses a different approach, trying to introduce the reader to a practical application of the methods, including data sets from climate simulations and MATLAB codes for the algorithms. All pictures and examples used in the book may be reproduced by using the data sets and the routines available in the book . Though the main thrust of the book is for climatological examples, the treatment is sufficiently general that the discussion is also useful for students and practitioners in other fields. Supplementary datasets are available via http://extra.springer.com

A Guide to Feynman Diagrams in the Many-Body Problem: Second Edition
by Richard D. Mattuck"A great delight to read." -- Physics TodayAmong the most fertile areas of modern physics, many-body theory has produced a wealth of fundamental results in all areas of the discipline. Unfortunately the subject is notoriously difficult and, until the publication of this book, most treatments of the topic were inaccessible to the average experimenter or non-specialist theoretician.The present work, by contrast, is well within the grasp of the nonexpert. It is intended primarily as a "self-study" book that introduces one aspect of many-body theory, i.e. the method of Feynman diagrams. The book also lends itself to use as a reference in courses on solid state and nuclear physics which make some use of the many-body techniques. And, finally, it can be used as a supplementary reference in a many-body course.Chapters 1 through 6 provide an introduction to the major concepts of the field, among them Feynman diagrams, quasi-particles and vacuum amplitudes. Chapters 7 through 16 give basic coverage to topics ranging from Dyson's equation and the ladder approximation to Fermi systems at finite temperature and superconductivity. Appendixes summarize the Dirac formalism and include a rigorous derivation of the rules for diagrams. Problems are provided at the end of each chapter and solutions are given at the back of the book.For this second edition, Dr. Mattuck, formerly of the H. C. Orsted Institute and the University of Copenhagen, added to many chapters a new section showing in mathematical detail how typical many-body calculations with Feynman diagrams are carried out. In addition, new exercises were included, some of which gave the reader the opportunity to carry out simpler many-body calculations himself. new chapter on the quantum field theory of phase transitions rounds out this unusually clear, helpful and informative guide to the physics of the many-body problem.

A Guide to Moist-Soil Wetland Plants of the Mississippi Alluvial Valley
by Michael L. Schummer Heath M. Hagy K. Sarah Fleming Joshua C. Cheshier James T. CallicuttMoist-soil wetlands are seasonally flooded areas that produce early-succession plant communities of grasses, sedges, and other herbaceous plants. Moist-soil wetland plants provide food and cover for a diversity of wildlife species, including waterfowl and other waterbirds. Thus, conservation and management of moist-soil plants has become a major component of wildlife conservation efforts in the Mississippi Alluvial Valley and elsewhere in North America. The authors combined their extensive experience working in managed and unmanaged wetlands from southern Missouri to southern Louisiana to produce this beautifully illustrated identification guide. A detailed, yet user friendly field guide to identify moist-soil plants of the Mississippi Alluvial Valley has not been available until now. Management to encourage the growth of moist-soil plants is a common conservation strategy used by state, federal, and private landowners to increase food and cover for wildlife. Thus, landowners must be able to identify moist-soil plants to meet their wildlife conservation goals. Landowners, scientists, wildlife biologists, and students alike will welcome this useful resource which includes 600 detailed color photographs of plants, images of seeds and tubers, and other helpful information to aid in identification. The book includes subsections of major plant groups occurring in moist-soil wetlands including aquatics, grasses, broadleaves, sedges and rushes, trees and shrubs, vines, and agricultural crops.

A Guide to Writing in the Sciences
by Patricia Patchet-Golubev Andrea A. GilpinWhile teaching writing to undergraduate science students, Gilpin and Patchet-Golubev discovered that although many relatively sophisticated manuals for scientific writing exist, most are aimed at mainly professionals or specialists and are of little practical use to the majority of students. This introductory guide fills that large gap.Direct and friendly in tone the book provides clear and concise explanations of the basic elements of scientific writing required of students. The various genres are detailed -- in particular lab reports and research essays - as well as scientific articles, poster presentations, proposals, and even essay exams. Similarities and differences among these genres are underlined in order to illustrate structural principles and to provide practical writing tips. A detailed chapter covers the elements of grammar and punctuation that are fundamental to all good writing; it also outlines some key points about scientific style in particular.Using accessible language throughout, the authors organize their material with helpful lists, copious examples, and boxed writing and research tips. There are several useful appendices (including a classification chart of organisms and an international units conversion chart), an index, and selected bibliography on science and technical writing. Unique in its field, this guide offers a practical and valuable guide to the basic principles and conventions of science writing.
