In this era of evidence-based medicine, one of the biggest challenges confronting acute medicine clinicians is keeping abreast with the rapidly changing recommendations that guide clinical practice. Oxford Desk Reference: Acute Medicine allows easy access to evidence-based materials on commonly encountered acute medical problems to ensure the optimum management of the acutely unwell patient. Collating all the research-based guidelines and protocols in one easily accessible place and presenting it in a uniform style, this practical book is hugely advantageous for a busy clinician as it is not always easy to access research-based guidelines and protocols when needed in the clinic. The book is designed so that each subject forms a self-contained topic in its own right. This makes the information simple to find, read, and absorb, so that the book can be consulted in the clinic or ward setting for information on the optimum management of a particular condition. Edited by three experts in acute medicine, this book should never be far from the acute medicine clinician's side.

X-ray computed tomography has been used for several decades as a tool for measuring the three-dimensional geometry of the internal organs in medicine. However, in recent years, we have seen a move in manufacturing industries for the use of X-ray computed tomography; first to give qualitative information about the internal geometry and defects in a component, and more recently, as a fully-quantitative technique for dimensional and materials analysis. This trend is primarily due to the ability of X-ray computed tomography to give a high-density and multi-scale representation of both the external and internal geometry of a component, in a non-destructive, non-contact and relatively fast way. But, due to the complexity of X-ray computed tomography, there are remaining metrological issues to solve and the specification standards are still under development. This book will act as a one-stop-shop resource for students and users of X-ray computed tomography in both academia and industry. It presents the fundamental principles of the technique, detailed descriptions of the various components (hardware and software), current developments in calibration and performance verification and a wealth of example applications. The book will also highlight where there is still work to do, in the perspective that X-ray computed tomography will be an essential part of Industry 4.0.

In this era of evidence-based medicine, one of the biggest challenges confronting clinicians is keeping abreast with the rapidly changing recommendations that guide clinical practice. It is not always easy to access research-based guidelines and protocols when needed in the clinic. Material isoften spread around various publications and web sites. Collating all the information in one easily accessible place and presenting it in a uniform style is hugely advantageous to a busy clinician. The Oxford Desk Reference - Acute Medicine allows easy access to evidence-based materials on commonlyencountered acute medical problems to ensure the optimum management of the acutely unwell patient. Acute Medicine is a growing and evolving specialty and now has its own curricula for training. This book collates key recommendations that a practising clinician needs to know and presents them in an easily accessible and uniform way allowing rapid assimilation of information. The book is edited bythree experts in Acute Medicine, including Derek Bell, the first chair of Acute Medicine, Richard Leach, author of Acute and Critical Care Medicine at a glance, and Kevin Moore, editor of the Oxford Handbook of Acute Medicine.

Additive manufacturing (AM) is a fast-growing sector with the ability to evoke a revolution in manufacturing due to its almost unlimited design freedom and its capability to produce personalised parts locally and with efficient material use. AM companies, however, still face technological challenges such as limited precision due to shrinkage, built-in stresses and limited process stability and robustness. Moreover, often post-processing is needed due to high roughness and remaining porosity. Qualified, trained personnel are also in short supply. In recent years, there have been dramatic improvements in AM design methods, process control, post-processing, material properties and material range. However, if AM is going to gain a significant market share, it must be developed into a true precision manufacturing method. The production of precision parts relies on three principles: Production is robust (i.e. all sensitive parameters can be controlled). Production is predictable (for example, the shrinkage that occurs is acceptable because it can be predicted and compensated in the design). Parts are measurable (as without metrology, accuracy, repeatability and quality assurance cannot be known). AM of metals is inherently a high-energy process with many sensitive and inter-related process parameters, making it susceptible to thermal distortions, defects and process drift. The complete modelling of these processes is beyond current computational power, and novel methods are needed to practicably predict performance and inform design. In addition, metal AM produces highly textured surfaces and complex surface features that stretch the limits of contemporary metrology. With so many factors to consider, there is a significant shortage of background material on how to inject precision into AM processes. Shortage in such material is an important barrier for a wider uptake of advanced manufacturing technologies, and a comprehensive book is thus needed. This book aims to inform the reader how to improve the precision of metal AM processes by tackling the three principles of robustness, predictability and metrology, and by developing computer-aided engineering methods that empower rather than limit AM design. Richard Leach is a professor in metrology at the University of Nottingham and heads up the Manufacturing Metrology Team. Prior to this position, he was at the National Physical Laboratory from 1990 to 2014. His primary love is instrument building, from concept to final installation, and his current interests are the dimensional measurement of precision and additive manufactured structures. His research themes include the measurement of surface topography, the development of methods for measuring 3D structures, the development of methods for controlling large surfaces to high resolution in industrial applications and the traceability of X-ray computed tomography. He is a leader of several professional societies and a visiting professor at Loughborough University and the Harbin Institute of Technology. Simone Carmignato is a professor in manufacturing engineering at the University of Padua. His main research activities are in the areas of precision manufacturing, dimensional metrology and industrial computed tomography. He is the author of books and hundreds of scientific papers, and he is an active member of leading technical and scientific societies. He has been chairman, organiser and keynote speaker for several international conferences, and received national and international awards, including the Taylor Medal from CIRP, the International Academy for Production Engineering.
