Book Description
“Eels [is] more than a fish book. It is an impassioned defense of nature itself. . . . [Prosek] passes on the truth that the often disdained eel, like all migratory fish, is vital and mysterious and worthy of our full effort to bring it back.” — New York Times Book Review “A wonderful account of far-flung travels in pursuit of the secrets of the earth’s most mysterious fish. . . . Fascinating and beautifully rendered.” — Peter Matthiessen Famous for his deeply informed, compulsively readable books on trout, James Prosek (whom the New York Times has called “the Audubon of the fishing world”) takes on nature’s quirkiest and most enigmatic fish: the eel. Fans of Mark Kurlansky’s Cod and The Big Oyster or Trevor Corson’s The Secret Life of Lobsters will love Prosek’s probing exploration of the hidden deep-water dwellers. With characteristically captivating prose and lavish illustrations, Prosek demystifies the eel’s unique biology and bizarre mating routines, and illuminates the animal’s varied roles in the folklore, cuisine, and commerce of a variety of cultures.

Book Description
to the Second Edition Since the first (1986) edition of this book, the numbers of installations, researchers, and research publications devoted to electron energy-loss spec troscopy (EELS) in the electron microscope have continued to expand. There has been a trend towards intermediate accelerating voltages and field-emission sources, both favorable to energy-loss spectroscopy, and sev eral types of energy-filtering microscope are now available commercially. Data-acquisition hardware and software, based on personal computers, have become more convenient and user-friendly. Among university re searchers, much thought has been given to the interpretation and utilization of near-edge fine structure. Most importantly, there have been many practi cal applications of EELS. This may reflect an increased awareness of the potentialities of the technique, but in many cases it is the result of skill and persistence on the part of the experimenters, often graduate students. To take account of these developments, the book has been extensively revised (over a period of two years) and more than a third of it rewritten. I have made various minor changes to the figures and added about 80 new ones. Except for a few small changes, the notation is the same as in the first edition, with all equations in SI units.

Book Description
As a food resource in both Eastern and Western countries, the eel is an important fish. Over the years, remarkable progress has been achieved in understanding the mysterious life cycle of eels that has fascinated scientists since the age of Aristotle. The spawning area of the Japanese eel was discovered and the migratory route of its larvae was elucidated. With the development of techniques for artificial induction of gonadal maturation, it became possible to obtain hatched larvae. Larval rearing to the leptocephalus stage, one of the most difficult tasks involved in eel culture, finally was achieved. By presenting these important breakthroughs, Eel Biology will be of great help in the development of effective management strategies for maintaining stable eel populations. With contributions by leading experts, this book is a valuable source for researchers as well as industry technicians in the fields of aquatic biology, aquaculture, and fisheries.

Book Description
This book explains concepts of transmission electron microscopy (TEM) and x-ray diffractometry (XRD) that are important for the characterization of materials. The fourth edition adds important new techniques of TEM such as electron tomography, nanobeam diffraction, and geometric phase analysis. A new chapter on neutron scattering completes the trio of x-ray, electron and neutron diffraction. All chapters were updated and revised for clarity. The book explains the fundamentals of how waves and wavefunctions interact with atoms in solids, and the similarities and differences of using x-rays, electrons, or neutrons for diffraction measurements. Diffraction effects of crystalline order, defects, and disorder in materials are explained in detail. Both practical and theoretical issues are covered. The book can be used in an introductory-level or advanced-level course, since sections are identified by difficulty. Each chapter includes a set of problems to illustrate principles, and the extensive Appendix includes laboratory exercises.

Book Description
Transmission Electron Microscope (TEM) is a very powerful tool for characterizing various types of materials. Using a light microscope, the imaging resolution is at several hundred nanometers, and for a Scanning Electron Microscope (SEM) at several nanometers. The imaging resolution of the TEM, however, can routinely reach several angstroms on a modem instrument. In addition, the TEM can also provide material structural information, since the electrons penetrate through the thin specimens, and chemical compositional information due to the strong electron-specimen atom interactions. This book provides a concise practical guide to the TEM user, starting from the beginner level, including upper-division undergraduates, graduates, researchers, and engineers, on how to learn TEM efficiently in a short period of time. Volume I covers the instrumentation, sample preparation, fundamental diffraction, imaging, analytical microscopy, and some newly developed microscopy techniques. This book may serve as a textbook for a TEM course or workshop, or a reference book for the TEM user to improve their TEM skills.

Book Description
Volume 27 of Reviews in Mineralogy provides a background to the TEM as a mineralogical tool, to give an introduction to the principles underlying its operation, and to explore mineralogical applications and ways in which electron microscopy can augment our knowledge of mineral structures, chemistry, and origin. Much time will be devoted to mineralogical applications. It provides sufficient information to allow mineralogists and petrologists to have an informed understanding of the data produced by transmission electron microscopy and to have enough knowledge and experience to undertake initial studies on their own. The opening chapters cover the principles of electron microscopy and chemical analysis using the TEM; while the following chapters consider mineralogical, petrological, and geochemical applications and their implications, for both low- and high-temperature geological environments. The Mineralogical Society of America sponsored a short courses in conjunction with their annual meetings with the Geological Society of America, and this volume represents the proceedings of the eighteenth in the sequence. This TEM course was convened October 23-25, 1992, at Hueston Woods State Park, College Comer, Ohio.

Book Description
This book explains much of what is known currently about freshwater eels, focusing on social and cultural aspects as well as science. A wealth of eel-related material is presented by scientists from around the world, including information on eel fishing, resources, distribution, aquaculture, economics, cuisine, environment and ecosystems, idioms, arts and crafts, tradition, legends, mythology, archaeology and even memorial services. Eels are important as food for humankind and are an interesting model for scientists studying animal migration and reproductive ecology. Their snake-like morphology differentiates them from most other fish, and their unpredictable behaviour that allows them to move over wet land and climb rocks adjacent to waterfalls attracts attention and evokes curiosity. Eels are therefore considered to be enigmatic creatures or metaphysical entities beyond human intelligence; indeed, they have been deified in parts of the world. In recent decades, however, with global populations of eels in sharp decline, some species face a real threat of extinction, and effective conservation strategies and measures are needed. Comparisons across these issues between various countries provide an image of a long-lasting relationship between eels and humankind, and encourage comprehensive and detailed understanding of eels from the perspectives of social, cultural and natural sciences. By promoting understanding of the close relationship between eels and humans, the broader public is engaged and public awareness of eel importance raised, helping to conserve these unique but endangered fish.
