Electric currents and electromagnetic fields have been applied to biological systems, particularly humans, with both therapeutic and pathological results. This text discusses biological responses to electric currents and electromagnetic fields, including medical applications and shock hazards. It covers fundamental physical and engineering principles of responses to short-term electrical exposure and emphasises human reactions, although animal responses are considered as well, and the treatment covers reactions from the just-detectable to the clearly detrimental. An important new chapter discusses standards for human exposure to electromagnetic fields and electric current and demonstrates how these standards have been developed using the principles treated in earlier chapters.

Bioelectricity (or bioelectromagnetism) relates to the study of biological electrical currents, and bioimpedance deals with the measurement of electrical conductivity. They are intimately linked to biomedical engineering, with major significance for development of novel medical devices, as well as the study of biological rhythms. This completely updated new edition remains the most comprehensive reference tool for this intricate, interdisciplinary field. The authors, both internationally recognized experts in the field, have thoroughly revised the entire text. It remains the only such work that discusses in detail dielectric and electrochemical aspects, as well as electrical engineering concepts of network theory. The highly effective, easy to follow organization has been retained, with new discussion of state-of-the-art advances in finite element analysis, endogenic sources, control theory, tissue electrical properties, and invasive measurements. There are two all new chapters on bioelectricity, along with an introduction to Geselowitz theory, the Maxwell basis of bioimpedance, and multivariate analysis as an alternative. * Increased emphasis on bioelectricity and potential clinical applications * Two all new chapters dealing with electrical properties of passive and excitable tissue * Expanded discussion of finite element modelling and a broad range of applications * Provides a complete ?all in one? reference source for a multidisciplinary, complex field * Includes many additional figures and all improved, newly drawn illustrations throughout

Electrostimulation is defined as the action of electrical energy on nerve and muscle OCo the two classes of excitable tissue. This cutting-edge resource offers you broad coverage of the subject, expanding the scope of electrostimulation discussions to include accidental, aversive, and possibly harmful biological effects of electrical energy. The book enables you to develop standards for human exposure to electric currents having various waveforms, determine classes of nerve fibers brought to excitation within specified regions of the body due to certain types of exposure, and quantify how harmonic distortions influence the excitability of sinusoidal extrostimulation. This practical reference also offers guidance in using the SENN (Spatially Extended Nonlinear Node) computer model that simulates the interaction of applied electric energy with myelinated neurons.Moreover, you learn how to compare efficacy and hazard potential of various stun weapons, assess unintended nerve stimulation from MRI exposure of patients with metallic implants, and compare the safety margins between electrostimulation thresholds of sensory and motor neurons relative to unintended cardiac excitation or painful sensory responses."

Work in the field of neuroprosthetics requires multidisciplinary teams, but these collaborators must meet on common ground to develop an understanding of the capabilities and limitations of each part of a bioengineering project. The Handbook of Neuroprosthetic Methods provides a comprehensive resource for the techniques, methodologies, and options available to properly design and undertake experiments within the field of neuroprosthetics. It combines the most commonly employed concepts, applications, and knowledge from the many disciplines associated with neuroprosthetic research to foster more effective, profitable, and productive collaborations. From basic neurophysiology to emerging technologies, this book provides a clear introduction to the entire range of neuroprosthetic systems. Each chapter includes background information, methodology, illustrative figures that clarify experimental methods, and tables that outline and compare experimental choices. The last part of each chapter provides practical applications and examples that relate the topic to the actual design and implementation of a neuroprosthetic system or device. Through its exploration of a variety of developmental processes, the book provides guidance on issues that have yet to be solved, strategies for solving such problems, and the pitfalls often encountered when developing neural prostheses. Whether you are new to or a veteran of the field, whether you work directly or indirectly with neuroprosthesis projects, the Handbook of Neuroprosthetic Methods provides an accessible common ground for all involved in neuroprosthetic design and research.

Ensuring safe and plentiful supplies of potable water (both now and for future generations) and developing sustainable treatment processes for wastewater are among the world’s greatest engineering challenges. However, sustainability requires investment of money, time and knowledge. Some parts of the world are already working towards this goal but many nations have neither the political will nor the resources to tackle even basic provision and sanitation. Combining theory and practice from the developing and developed worlds with high- and low-tech, high- and low-cost solutions, this book discusses fundamental and advanced aspects of water engineering and includes: water resource issues including climate change, water scarcity, economic and financial aspects requirements for sustainable water systems fundamentals of treatment and process design industrial water use and wastewater treatment sustainable effluent disposal sustainable construction principles With integrated theory, design and operation specifications for each treatment process, this book addresses the extent to which various treatment methods work in theory as well as how cost effective they are in practice. It provides a nontechnical guide on how to recover and reuse water from effluent, which is suitable for those in water resource management, environmental planning, civil and chemical engineering.
