The 6th edition of a well-known and much used standard text in the field. This book covers all aspects of the biochemical abnormalities caused by various diseases and how they relate to the biochemical changes in the blood, urine, cerebrospinal fluid, joint fluids, other body fluids and in cells. The purpose is to provide the fundamental bases for understanding the biochemical changes that occur in disease processes and in turn to provide the rationale for applying this understanding to the diagnosis of the disease process. A substantial appendix is provided so that the user can quickly identify the reference ranges for a large number of animal species.* An appendix is provided in the book so that the user can quickly identify the reference ranges for a large number of animal species* Explains what biochemical changes occur in disease processes and provides the rationale for applying this understanding to the diagnosis of the disease process

Solar Physics publishes up to two Topical Issues per year that focus on areas of especially vigorous and active research. The present Topical Issue contains papers of recent results on the solar corona, as well as on the transition region and low solar wind. The majority of these papers, which were all refereed in accordance with the standards of Solar Physics, were presented in August 1999 at a workshop held in Monterey, California. The authors were offered the opportunity to present relevant parts of their contributions on an accompanying CD ROM of this Topical Issue. The Sun's magnetic field is responsible for the spectacularly dynamic and intri­ cate phenomenon that we call the corona. The past decade has seen an enormous increase in our understanding of this part of the solar outer atmosphere, both as a result of observations and because of rapid advances in numerical studies. The Yohkoh satellite has observed the Sun now for over eight years, producing spectac­ ular sequences of images that convey the complexity of the corona. The imaging and spectroscopic instruments on SOHO have added information on the cooler part of the corona. And since April of 1998 TRACE has given us very high resolution images of the 1-2 MK corona, at cadences that allow detailed observations of field oscillations, loop evolution, mass ejecta, etc.

This text focuses on the advances in our understanding of solar convection and activity, and on new methods and results of helioseismic diagnostics of the internal structures and dynamics of solar convection and active regions. The methods of local helioseismology (time-distance tomography, ring-diagram analysis, acoustic imaging, and holography) have provided promising results on the deep structure of large-scale convection and flows, emerging active regions, and sunspots. The book includes reviews and contributed papers presented at the SOHO-9 Workshop held on July 12-15, 1999, at Stanford University, California, USA. It provides a comprehensive overview of the current status of the field and presents new ideas and approaches to helioseismic diagnostics and theoretical modelling of the physical processes inside the Sun. The book is recommended for graduate students and specialists in solar physics, astrophysics, and geophysics.

The Sun's magnetic field is responsible for the spectacularly dynamic and intricate phenomenon that we call the corona. The past decade has seen an enormous increase in our understanding of this part of the solar outer atmosphere, both as a result of observations and because of rapid advances in numerical studies. The YOHKOH satellite has observed the Sun now for over six years, producing spectacular sequences of images that convey the complexity of the corona. The imaging and spectroscopic instruments on SOHO have added information on the cooler part of the corona. And since April of 1998 TRACE has given us very high resolution images of the 1-2 MK corona, at cadences that allow detailed observations of field oscillations, loop evolution, mass ejecta, etc. This volume contains papers contributed to a workshop (held in August 1999, in Monterey, California) that was dedicated to an exploration of the most recent results on the solar corona, as well as on the transition region and low solar wind.The diverse presentations at the meeting revolved around one key theme: the entire outer atmosphere of the Sun is intrinsically dynamic, evolving so rapidly that even the concept of a single local temperature for a single fluid often breaks down. Moreover, the corona is an intrinsically nonlinear and nonlocal medium. These aspects are discussed in these proceedings that include both papers that review recent developments (both based on observations and on theoretical/numerical modeling), and original research papers based on observations from many different observatories. The papers presented at the meeting add up to such a size that they are distributed over two Topical Issues of Solar Physics (December 1999 and April 2000), which are reprinted in these bound volumes.

Most papers in this book were presented at the SOHO-9 Workshop 'Helioseismic Diagnostics of Solar Convection and Activity', held on 12-15 July 1999 at Stanford University, California, U.S.A. Some papers which were not presented at the work­ shop have been added, after authors had been invited in Solar News to contribute to this book. All papers submitted to this book have been refereed, and only those of high scientific quality were accepted for publication. The book focuses on the recent advances in our understanding of solar con­ vection and activity, and on methods and results of helioseismic diagnostics of the internal structures and dynamics of solar convection and active regions. The methods of local helioseismology (time-distance tomography, ring-diagram analy­ sis, acoustic imaging and holography), intensively developed in the past few years, have provided promising results on the deep structure of large-scale convection and flows, emerging active regions, and sunspots. Along with the traditional 'global' helioseismology based on frequencies of resonant oscillation modes, the local-area techniques have become increasingly important for studying the solar interior and the mechanisms of solar activity. The new high-resolution helioseismology projects 'Solar Oscillation Investiga­ tionlMichelson Doppler Imager' (SOIlMDI) on board SOHO, and ground-based 'Global Oscillation Network Group' (GONG) have provided a tremendous amount of solar oscillation data. Extracting from these data the information about the in­ ternal properties and dynamics of the Sun, and using this information in theoretical models and space weather forecasts are new challenges in solar physics.
