The association between poor nutrition and disease is well established. Integrating nutritional sciences into clinical practice offers a valuable tool to improve patient care and prognosis, particularly within the critical care environment where nutrition is often overlooked. However, optimizing nutritional support offers a safe and simple adjunct to more expensive and technologically challenging treatments for these complex patients. This volume provides comprehensive guidelines for the nutritional support of critically ill patients and is valuable reading for doctors, nurses, dieticians and practitioners working within the critical care environment. It begins by discussing nutritional physiology and patient assessment, providing an essential foundation for planning and managing the dietary requirements of critically ill patients. Internationally-recognized authors present evidence-based guidelines for managing various groups, including surgical patients, patients with burns, and patients with renal failure. The implications of enteral vs. parenteral nutrition, timing of nutritional support, therapeutic strategies, and management of complications are discussed.
Most astronomers believe that the universe began about 15 billion years ago when an explosion led to its expansion and cooling. The present state of the universe compels us to believe that the universe was extremely hot and dense in its infancy. In the beginning there was intense radiation. The photons produced equal amounts of matter and antimatter and a plasma soup of particles and antiparticles was present. Plasma is the first state of matter from which all the other states originated. This book discusses the diversity of cosmic and terrestrial plasmas found in the early universe, galactic and intergalactic media, stellar atmospheres, interstellar spaces, the solar system and the Earth's ionosphere, and their observability with the most recent telescopes such as the Chandra X-ray telescope and gamma ray telescopes. It deals with different ways of creating plasmas such as thermal, pressure and radiative ionization for laboratory and cosmic plasmas.
How did the Sun evolve, and what will it become? What is the origin of its light and heat? How does solar activity affect the atmospheric conditions that make life on Earth possible? These are the questions at the heart of solar physics, and at the core of this book. The Sun is the only star near enough to study in sufficient detail to provide rigorous tests of our theories and help us understand the more distant and exotic objects throughout the cosmos. Having observed the Sun using both ground-based and spaceborne instruments, the authors bring their extensive personal experience to this story revealing what we have discovered about phenomena from eclipses to neutrinos, space weather, and global warming. This second edition is updated throughout, and features results from the current spacecraft that are aloft, especially NASA's Solar Dynamics Observatory, for which one of the authors designed some of the telescopes.
