Tables of Spectra of Hydrogen, Carbon, Nitrogen, and Oxygen Atoms and Ions completely updates Charlotte E. Moore's energy levels and multiplet tables derived from analyses of optical spectra of hydrogen, carbon, nitrogen, and oxygen. The book contains data for neutrals and for all stages of ionization. Configurations, term designations, J-values, energy levels, and ionization potentials are provided as well. The book will benefit astronomers, atomic and optical physicists, plasma physicists, and chemists.

This new, fourth, edition of Allen's classic Astrophysical Quantities belongs on every astronomer's bookshelf. It has been thoroughly revised and brought up to date by a team of more than ninety internationally renowned astronomers and astrophysicists. While it follows the basic format of the original, this indispensable reference has grown to more than twice the size of the earlier editions to accommodate the great strides made in astronomy and astrophysics. It includes detailed tables of the most recent data on: - General constants and units - Atoms, molecules, and spectra - Observational astronomy at all wavelengths from radio to gamma-rays, and neutrinos - Planetary astronomy: Earth, planets and satellites, and solar system small bodies - The Sun, normal stars, and stars with special characteristics - Stellar populations - Cataclysmic and symbiotic variables, supernovae - Theoretical stellar evolution - Circumstellar and interstellar material - Star clusters, galaxies, quasars, and active galactic nuclei - Clusters and groups of galaxies - Cosmology. As well as much explanatory material and extensive and up-to-date bibliographies.

Introduction to Biological Imaging Discover what biological imaging is able to accomplish in this up-to-date textbook One of the fundamental goals of biology is to understand how living organisms establish and maintain their spatiotemporal organization of the biochemical, cell biological and developmental biology processes that sustain life. Biological systems are inherently complex with a large number of components needed to sustain cellular function. In order to understand any complex system, one must determine its composition by identifying the components it is made of, how each of these components function and carry out their specific task, and how they interact with one another to function together. To grasp the link of such changes to physiological cell and tissue function and/or pathogenesis/disease progression, we need to understand how modifications alter macromolecular function, macromolecular interactions, and/or spatiotemporal distribution and overall supramolecular structural organization. Biological imaging holds the key to understanding spatiotemporal organization, and will thus be increasingly important for the next generations of biological and biochemical researchers. Introduction to Biological Imaging provides the first comprehensive textbook surveying this subject. It elucidates the fundamental principles underlying the capture and production of bioimages, the requirements of image analysis and interpretation, and some key problems and solutions in bioimaging. It includes everything experimental biologists need to incorporate appropriate bioimaging solutions into their work. Introduction to Biological Imaging readers will also find: Coverage of all major types of biological imaging, including medical imaging, cellular imaging, macromolecular imaging, and more Advice on preparing samples for various imaging methods Specific examples in each chapter connecting bioimaging process to the production of real experimental data Introduction to Biological Imaging is a valuable introduction for undergraduate or graduate students in courses relating to bioimaging, as well as scientists and researchers in the biological and medical fields who want a one-stop reference for the full range of imaging techniques.
