Covering the entire spectrum of this fast-changing field, Diagnostic Imaging: Pediatrics, fourth edition, is an invaluable resource for pediatric radiologists, general radiologists, and trainees—anyone who requires an easily accessible, highly visual reference on today's pediatric imaging. Dr. A. Carlson Merrow, Jr., and his team of highly regarded experts provide up-to-date information on recent advances in technology and safety in the imaging of children to help you make informed decisions at the point of care. The text is lavishly illustrated, delineated, and referenced, making it a useful learning tool as well as a handy reference for daily practice. - Serves as a one-stop resource for key concepts and information on pediatric imaging, including a wealth of new material and content updates on more than 400 diagnoses - Features more than 2,500 illustrations including radiologic images, full-color illustrations, endoscopic and bronchoscopic photographs, clinical photos, and gross pathology images - Features updates from cover to cover including specifics from revised disease classifications and new terminology in best practices recommendations for radiologic reporting - Reflects evolving imaging technology in conjunction with increased awareness of radiation, contrast, and anesthesia safety in children, and how these advances continue to alter pediatric imaging approaches - Uses bulleted, succinct text and highly templated chapters for quick comprehension of essential information at the point of care
Molecular studies reveal highly ordered geographic patterns in plant and animal distributions. The tropics illustrate these patterns of community immobilism leading to allopatric differentiation, as well as other patterns of mobilism, range expansion, and overlap of taxa. Integrating Earth history and biogeography, Molecular Panbiogeography of the Tropics is an alternative view of distributional history in which groups are older than suggested by fossils and fossil-calibrated molecular clocks. The author discusses possible causes for the endemism of high-level taxa in tropical America and Madagascar, and overlapping clades in South America, Africa, and Asia. The book concludes with a critique of adaptation by selection, founded on biogeography and recent work in genetics.
The idea that current methods of food production are not sustainable in the long-term is a controversial topic. This book provides information that will advance a form of livestock production that meets the long- and short-term goals of human food production, minimizing degradation of natural resources. Important concerns regarding food safety, particularly antibiotic and chemical residues in meat, milk and other livestock foods, have stimulated renewed interest in alternative methods of promoting livestock health. Alternative Health Practices for Livestock is the first compilation of its kind for veterinarians, agriculture extension educators and livestock producers. It provides a well-referenced overview of some of the alternative livestock practices currently being examined. Key Features: A much needed information source on alternative health for large animals Contributions from veterinarians, farmers, extension educators and university professors Discusses the necessity for more validated scientific assessments of alternative and herbal therapies in livestock production Includes chapters on ways to promote alternative methods of health care for livestock, including steps to obtain research funding.
