This textbook aims to ensure that advances in medical textiles are addressed and that recent developments are able to be appreciated and understood not only by medical practitioners and healthcare personnel but also by textile scientists and technologists. The idea is to stimulate collaborative research and development in the field of medical textiles and to equip researchers with an understanding of the steps they need to take to ensure that their efforts, be they to develop new devices for implantation or items for external application, are carried out in such a way as to improve their effectiveness and enhance the prospects for their implementation. Attention is drawn to the need to improve outcomes in the practical setting and to guidance on the detailed planning required prior to engaging in experimental work. Standard tests can help researchers to monitor performance, but for some important applications such as those required to demonstrate antimicrobial and fluid-repellent performance in most items of protective wear, standard tests consistently fall seriously short in terms of predicting how well they might work in the practical setting. Guidance is therefore given for their further development.Chapters within the textbook cover: The history of innovation within medical textiles with particular attention given to key concepts of the latter part of the 19th Century and subsequent associated developments. Textile and polymer science underpinning fibres, fabrics, nano-fibre technology and the functional finishes that can be applied to enhance the performance of medical textile products. Woven, knitted, nonwoven and braided fabrics and the key performance characteristics of each fabric type which make them particularly suited to specific medical textile roles such as mesh, grafts, filtration and scaffolds for tissue engineering. Implantable medical textiles, non-implantable medical textiles, health and hygiene products and extracorporeal devices that use textile products. Legislative requirements for medical devices. The design of experiments and suitability for purpose of textile test methods. Case studies to illustrate how medical textiles are applied in practice.The book provides essential reading for textile professionals, biomedical engineers, and others involved in the research, design and engineering of medical and healthcare appliances, and for those employed in the medical profession wishing to gain new insights into the wealth of materials at their disposal.

This book provides an accessible introduction to the principles and tools for modeling, analyzing, and synthesizing biomolecular systems. It begins with modeling tools such as reaction-rate equations, reduced-order models, stochastic models, and specific models of important core processes. It then describes in detail the control and dynamical systems tools used to analyze these models. These include tools for analyzing stability of equilibria, limit cycles, robustness, and parameter uncertainty. Modeling and analysis techniques are then applied to design examples from both natural systems and synthetic biomolecular circuits. In addition, this comprehensive book addresses the problem of modular composition of synthetic circuits, the tools for analyzing the extent of modularity, and the design techniques for ensuring modular behavior. It also looks at design trade-offs, focusing on perturbations due to noise and competition for shared cellular resources. Featuring numerous exercises and illustrations throughout, Biomolecular Feedback Systems is the ideal textbook for advanced undergraduates and graduate students.For researchers, it can also serve as a self-contained reference on the feedback control techniques that can be applied to biomolecular systems. * Provides a user-friendly introduction to essential concepts, tools, and applications* Covers the most commonly used modeling methods* Addresses the modular design problem for biomolecular systems* Uses design examples from both natural systems and synthetic circuits* Solutions manual (available only to professors at press.princeton.edu)* An online illustration package is available to professors at press.princeton.edu

The essential introduction to the principles and applications of feedback systems—now fully revised and expandedThis textbook covers the mathematics needed to model, analyze, and design feedback systems. Now more user-friendly than ever, this revised and expanded edition of Feedback Systems is a one-volume resource for students and researchers in mathematics and engineering. It has applications across a range of disciplines that utilize feedback in physical, biological, information, and economic systems.Karl Åström and Richard Murray use techniques from physics, computer science, and operations research to introduce control-oriented modeling. They begin with state space tools for analysis and design, including stability of solutions, Lyapunov functions, reachability, state feedback observability, and estimators. The matrix exponential plays a central role in the analysis of linear control systems, allowing a concise development of many of the key concepts for this class of models. Åström and Murray then develop and explain tools in the frequency domain, including transfer functions, Nyquist analysis, PID control, frequency domain design, and robustness.Features a new chapter on design principles and tools, illustrating the types of problems that can be solved using feedbackIncludes a new chapter on fundamental limits and new material on the Routh-Hurwitz criterion and root locus plotsProvides exercises at the end of every chapterComes with an electronic solutions manualAn ideal textbook for undergraduate and graduate studentsIndispensable for researchers seeking a self-contained resource on control theory

The large parks and green infrastructure presented here illustrate the diverse uses and many benefits of large urban parks across 30 major cities. Demand for large urban parks emerged at the height of the First Industrial Revolution in the mid-1800s, when large urban parks represented new ideas of accessible public spaces, often established on land previously owned by aristocracy, royalty or the army. They represented new ideas on how city life could be improved and how large green spaces could enhance urban citizens’ physical and psychological well-being (e.g. Birkenhead Park in Liverpool, Bois de Boulogne in Paris, Tiergarten in Berlin and Central Park in New York City). Today, large urban parks are habitats for biodiversity and spaces of climate change adaptation. For people living in cities, this biodiversity may represent high cultural, recreational and aesthetic values, but is also important for other aspects of health and well-being, for example by reducing the urban heat island effect, air pollution and risks of flooding. At a time when we are seriously reconsidering how we live in cities and our urban quality of life, while also grappling with serious challenges of climate change, the authors of this book detail the much-needed evidence, pathways and vision for a future of more liveable, resilient cities where large urban parks are at the core. This book will help park managers, NGOs, landscape architects and city planners to develop the green city of the future.

At a time when digital technologies are impacting on the success and sustainability of traditional models of journalism, hyperlocal journalism seeks to restore journalistic integrity, build community, incite change and engage audiences. This book argues for the increased importance of these new forms of localized reporting in the digital age.Hyperlocal Journalism and Digital Disruptions begins with the fundamental question of what hyperlocal journalism is, then focuses on three case studies which illustrate its potential to thrive when the right balance is struck between audience engagement, investment and respect. Each case study examines a different start-up in Australia and New Zealand. Although the notion of hyperlocal journalism is not new, the ways in which these regionalized stories are now being told has evolved. This book demonstrates the increased necessity for tailored approaches to creating and providing hyperlocal journalism in order to engage targeted audiences, meet their needs for news and reclaim authenticity and credibility for journalism.This is a valuable resource for researchers, academics, students and practitioners in the areas of Digital Journalism and Media Studies generally.
