Marine Concrete Structures: Design, Durability and Performance comprehensively examines structures located in, under, or in close proximity to the sea. A major emphasis of the book is on the long-term performance of marine concrete structures that not only represent major infrastructure investment and provision, but are also required to operate with minimal maintenance. Chapters review the design, specification, construction, and operation of marine concrete structures, and examine their performance and durability in the marine environment. A number of case studies of significant marine concrete structures from around the world are included which help to reinforce the principles outlined in earlier chapters and provide useful background to these types of structures. The result is a thorough and up-to-date reference source that engineers, researchers, and postgraduate students in this field will find invaluable.

Concrete and cement-based materials must operate in increasingly aggressive aqueous environments, which may be either natural or industrial. These materials may suffer degradation in which ion addition and/or ion exchange reactions occur, leading to a breakdown of the matrix microstructure and consequent weakening. Sometimes this degradation can be extremely rapid and serious such as in acidic environments, while in other cases degradation occurs over long periods. Consequences of material failure are usually severe – adversely affecting the health and well-being of human communities and disturbing ecological balances. There are also large direct costs of maintaining and replacing deteriorated infrastructure and indirect costs from loss of production during maintenance work, which place a great burden on society. The focus of this book is on addressing issues concerning performance of cement-based materials in aggressive aqueous environments , by way of this State-of-the-Art Report. The book represents the work of many well-known and respected authors who contributed chapters or parts of chapters. Four main themes were addressed: I. Nature and kinetics of degradation and deterioration mechanisms of cement-based materials in aggressive aqueous environments, II. Modelling of deterioration in such environments, III. Test methods to assess performance of cement-based materials in such environments, and which can be used to characterise and rate relative performance and inform long term predictions, IV. Engineering implications and consequences of deterioration in aggressive aqueous environments, and engineering approaches to the problem.

This book provides a comprehensive overview of exercise physiology in patients with congenital heart disease and other pediatric cardiopulmonary disorders. It begins with an in-depth but pragmatic discussion of exercise physiology and the cardiopulmonary adaptations to physical activity, followed by a review of the conduct and interpretation of cardiopulmonary exercise tests. Subsequent chapters discuss exercise physiology and testing in patients with a variety of congenital heart diseases, including tetralogy of Fallot, Fontan physiology, transposition of the great arteries, aortic valve disease, and coarctation of the aorta. Additional chapters analyze other conditions commonly encountered by pediatric and congenital cardiologists such as pulmonary vascular disease, cardiomyopathies, heart transplants, and metabolic disorders. The book also examines the role of exercise testing in patients with electrophysiologic issues such as Wolff-Parkinson-White Syndrome, long QT syndrome, atrioventricular node dysfunction, and pacemakers. The presentations are enhanced by data from Boston Children’s Hospital’s vast experience with clinical exercise testing. The textbook concludes with a series of interesting and illustrative cases that build on the earlier chapters, present some fascinating physiology, and provide real-world examples of how exercise testing can inform clinical decision making. Exercise Physiology for the Pediatric and Congenital Cardiologist is a detailed, practical reference for clinicians and other health care providers engaged in exercise testing for children and adults with congenital heart disease and other conditions that may be encountered by the pediatric and congenital cardiologist. It is an essential resource for physicians, medical students, and exercise physiologists as well as researchers in cardiology, pediatrics, and cardiopulmonary fitness.
