This text focuses on conservation laws in magnetohydrodynamics, gasdynamics and hydrodynamics. A grasp of new conservation laws is essential in fusion and space plasmas, as well as in geophysical fluid dynamics; they can be used to test numerical codes, or to reveal new aspects of the underlying physics, e.g., by identifying the time history of the fluid elements as an important key to understanding fluid vorticity or in investigating the stability of steady flows. The ten Galilean Lie point symmetries of the fundamental action discussed in this book give rise to the conservation of energy, momentum, angular momentum and center of mass conservation laws via Noether’s first theorem. The advected invariants are related to fluid relabeling symmetries – so-called diffeomorphisms associated with the Lagrangian map – and are obtained by applying the Euler-Poincare approach to Noether’s second theorem. The book discusses several variants of helicity including kinetic helicity, crosshelicity, magnetic helicity, Ertels’ theorem and potential vorticity, the Hollman invariant, and the Godbillon Vey invariant. The book develops the non-canonical Hamiltonian approach to MHD using the non-canonical Poisson bracket, while also refining the multisymplectic approach to ideal MHD and obtaining novel nonlocal conservation laws. It also briefly discusses Anco and Bluman’s direct method for deriving conservation laws. A range of examples is used to illustrate topological invariants in MHD and fluid dynamics, including the Hopf invariant, the Calugareanu invariant, the Taylor magnetic helicity reconnection hypothesis for magnetic fields in highly conducting plasmas, and the magnetic helicity of Alfvén simple waves, MHD topological solitons, and the Parker Archimedean spiral magnetic field. The Lagrangian map is used to obtain a class of solutions for incompressible MHD. The Aharonov-Bohm interpretation of magnetic helicity and cross helicity is discussed. In closing, examples of magnetosonic N-waves are used to illustrate the role of the wave number and group velocity concepts for MHD waves. This self-contained and pedagogical guide to the fundamentals will benefit postgraduate-level newcomers and seasoned researchers alike.

Dedicated to the critical management of acutely ill adults with congenital heart disease, this comprehensive book discusses the many challenges faced in the management of these patients, who require intensive inter- and trans-disciplinary care. It provides the first universal review of the practical management of patients with these complex conditions, who survive into adulthood with congenital cardiac malformations and are often affected by other morbidities. For this reason, it reflects a consistent interaction and collaboration between several disciplines: pediatric and adult cardiology, cardiac surgery, pediatric and adult cardiac intensive care, anesthesia, intensive care nursing, nutrition, psychology and many other specialties. It offers concise and pragmatic recommendations, and provides basic and advanced concepts that allow caregivers to anticipate, prevent and effectively treat such pathologies. The book also includes chapters focusing on cardiac-database and risk-factorassessment, organizational and operational topics, advanced mechanical circulatory assistance and pharmacology.Whilst bringing together top international experts who are leading reference programs around the globe, this book is an indispensable teaching tool for clinicians and caregivers involved in the management of critically ill adults with congenital heart disease.
