A revision of the classic text on railroad engineering, considered the ``bible'' of the field for three decades. Presents railroad engineering principles quantitatively but without excessive resort to mathematics, and applies these principles to day-by-day design, construction, operation, and maintenance. Relates practice to principles in an orderly, sequential pattern (subgrade, ballast, ties, rails). Applicable to both conventional railroads and rapid transit systems.

Neonatal nutrition has a pivotal role in normal child development and is of even greater importance in the sick or premature neonate. This 2006 edition includes a comprehensive account of the basic science, metabolism and nutritional requirements of the neonate, and a greatly expanded number of chapters dealing in depth with clinical issues ranging from IUGR, intravenous feeding, nutritional therapies for inborn errors of metabolism, and care of the neonatal surgical patient. Evolving from these scientific and clinical aspects, the volume highlights the important long-term effects of fetal and neonatal growth on health in later life. In addition, there are very practical chapters on methods and techniques for assessing nutritional status, body composition, and evaluating metabolic function.

This book is a thorough introduction to climate science and global change. The author is a geologist who has spent much of his life investigating the climate of Earth from a time when it was warm and dinosaurs roamed the land, to today's changing climate.

The management of the extremes of plasma or blood glucose concentrations, hypoglycemia and hyperglycemia, in the first 48 hours of life to several days of life in both preterm and term newborn infants is one of the most frequently encountered issues clinicians face. The concentrations of glucose upon which we base our decision-making remain more a matter of expert opinion than being evidence-based, and a consensus on blood glucose concentrations that should be treated in the newborn has not been definitive enough .This lack of consensus has led to further confusion for clinician as two pediatric organizations, the Committee on the Fetus and Newborn of the American Academy of Pediatrics (AAP) and the Pediatric Endocrine Society (PES), have recently provided expert opinion on the management of neonatal hypoglycemia that suggested different ranges of actionable blood glucose concentrations. The AAP guidance applies only to the first 24 h of life, while the PES strategy focuses on infants beyond 48 h of life with the emphasis on assuring that cases of persistent hypoglycemia are identified before these infants are discharged.This book provides an approach to neonatal hypo- and hyperglycemia that incorporates opinions from authoritative organizations, the literature, and clinical practice and provides management that meets the newborns’ energy requirements while still promoting successful breastfeeding and preventing unnecessary NICU admissions. It is also helpful medicolegally, as both disorders, but particularly hypoglycemia, have been the subject of numerous legal cases, often decided on misinformation or prejudicial bias.Written by experts in the field, Disorders of Neonatal Glycemia provides valuable details to help clinicians recognize and understand all the grey areas in these two disorders and recognize the difference among standard guidelines, such as those from the AAP and the PES.
