The exceptional mechanical, optical, surface and biocompatibility properties of nanodiamond have gained it much interest. Exhibiting the outstanding bulk properties of diamond at the nanoscale in the form of a film or small particle makes it an inexpensive alternative for many applications. Nanodiamond is the first comprehensive book on the subject. The book reviews the state of the art of nanodiamond films and particles covering the fundamentals of growth, purification and spectroscopy and some of its diverse applications such as MEMS, drug delivery and biomarkers and biosensing. Specific chapters include the theory of nanodiamond, diamond nucleation, low temperature growth, diamond nanowires, electrochemistry of nanodiamond, nanodiamond flexible implants, and cell labelling with nanodiamond particles. Edited by a leading expert in nanodiamonds, this is the perfect resource for those new to, and active in, nanodiamond research and those interested in its applications.

The polarity of a sentence is crucial for its meaning. It is thus hardly surprising that languages have developed devices to highlight this meaning component and to contrast statements with negative and positive polarity in discourse. Research on this issue has started from languages like German and Dutch, where prosody and assertive particles are systematically associated with polarity contrast. Recently, the grammatical realization of polarity contrast has been at the center of investigations in a range of other languages as well. Core questions concern the formal repertoire and the exact meaning contribution of the relevant devices, the kind of contrast they evoke, and their relation to information structure and sentence mood. This volume brings together researchers from a theoretical, an empirical, and a typological orientation and enhances our understanding of polarity with the help of in-depth analyses and cross-linguistic comparisons dealing with the syntactic, semantic, pragmatic and/or prosodic aspects of the phenomenon.

The first edition of this definitive text ran to 24 chapters. The second edition, reflecting the explosive growth of interest in echo-enhancement, contains 44. The first section deals with some of the most important emerging issues and technologies and covers harmonic imaging, the use of echo-enhancers to provide quantitative information, and the application of enhanced power Doppler to tissue imaging. The second, on contrast echocardiography, explores the use of echo-enhancement during transesophageal imaging. One chapter describes the use of contrast-enhancement transesophageal imaging to determine coronary flow reserve and another gives a detailed account of the application of the technique to the evaluation of left ventricular function. Other authors describe the intraoperative use of contrast echocardiography and discuss the potential of myocardial contrast echocardiography to replace thallium scintigraphy. Another chapter covers the emerging technique of transient response imaging and its role in the assessment of myocardial perfusion, and two chapters are devoted to three-dimensional contrast echocardiographic assessment of myocardial perfusion. Use of echo-enhancement in the evaluation of peripheral circulation is discussed in chapters on carotid and peripheral arterial flow imaging and others that describe renal and hepatic vascular imaging. The newer applications of echo-enhancement outside the cardiovascular system are described in three chapters devoted to the visualization of tumour vasculature. The final chapters look to the future and cover the imaging of intramyocardial vasculature, the development of site-specific agents and the emergence of the new acoustically active agents.

To our knowledge, this is the first book dealing exclusively with myocardial contrast two-dimensional echocardiography (MC-2DE), a new and exciting diagnostic methodology for assessment of myocardial perfusion, which has seen rapid development and has now entered the clinical stage. The experi mental research and human applications have been described in technical papers published in a variety of journals, but our objective is to provide the reader with a comprehensive and concentrated overview of the field and of the current state of the art. To facilitate appreciation of the significant ad vances made and issues yet to be resolved, we are pleased to have several well known specialists contribute their own assessment of specific aspects of MC- 20E and illustrate the method's principles as well as applications. We were faced with inevitable overlaps and some repetitions in the discussion of quan titative potentials or limilations of the methodology. Rather than strictly 'streamlining' the text, we decided to accept some redundancy in the interest of presenting a diversity of points of views, reflecting the current evolutionary state of MC-20E. Following a brief reference to the established clinical contrast echocardiog raphy, recent developments and validations of the specialized MC-2DE tech nique are reviewed, bearing in mind that the field is in a flux and some of the ongoing activities have not as yet been formally reported. Mechanisms of the echo contrast and several new agents are decribed next, and an additional chapter illustrates current thoughts-on optimizing the echo contrast medium.

The book Theory and Practice of Contrast completes, corrects and integrates the foundations of science and humanities, which include: theory of art, philosophy (aesthetics, epistemology, ontology, axiology), cognitive science, theory of information, theory of complexity and physics. Through the integration of these distant disciplines, many unresolved issues in contemporary science have been clarified or better understood, among others: defining impact (contrast) and using this definition in different fields of knowledge; understanding what beauty/art is and what our aesthetic preferences depend on; deeper understanding of what complexity and information are in essence, and providing their general definitions. Complexity means integration, value and goodness - concepts that seem to be neglected today. The book also has a high degree of integration/complexity, although each chapter introduces a new issue. The last chapter: "Binary Model of the Universe" draws attention to the need for including in physics the analysis of our mind and the resulting new possibilities, which include the mentioned (digital) model of the universe. Despite the difficult issues raised here, this study is written in accessible language and may be interesting not only for scientists and academics.

This book takes contrast, an issue that has been central to phonological theory since Saussure, as its central theme, making explicit its importance to phonological theory, perception, and acquisition. The volume brings together a number of different contemporary approaches to the theory of contrast, including chapters set within more abstract representation-based theories, as well as chapters that focus on functional phonetic theories and perceptual constraints. This book will be of interest to phonologists, phoneticians, psycholinguists, researchers in first and second language acquisition, and cognitive scientists interested in current thinking on this exciting topic.

Why a book on contrast echocardiography? Over the past dozen years enough experience has accumulated to warrant a more extensive treatment of this method. Furthermore, there are new developments that suggest increased clinical utility for contrast echocardiography in the future. This book aims to summarize the "state of the art" for those interested in echocardiography - presumably mainly cardiologists, but here and there those of a more technical bent will find useful information as well. We feel that a more basic understanding of microbubble dynamics is necessary to advance research for such applications as transmission through the lungs, videodensitometric quantitation of cardiac output, intracardiac shunts, etc. All of these topics are extensively dealt with. The reader will note that many of the clinical chapters are written by pediatric cardiologists. This is only natural, since shunt detection and analysis of flow relationships are relatively more important in congenital heart diseases, and cur rently represent the most important uses for contrast echo cardiography in day-to day practice.

This is the third edition of a very successful book that originally emerged from the work of a committee set up by the European Society of Urogenital Radiology in 1994 to consider the safety of contrast media used for diagnostic imaging. The new edition not only fully updates the previous edition, but also includes new chapters on complex topics such as pediatric issues and practical aspects of off-label contrast media use. Comprehensive consideration is given to the many different safety issues relating to iodine-based contrast media, gadolinium-based contrast media, microbubbles for ultrasound, and barium sulfate. The text includes chapters on both acute and delayed non-renal adverse reactions and on renal adverse reactions. All of the questions frequently raised in radiological practice are addressed. This book, presented in a handy, easy-to-use format, provides an invaluable, unique, and unparalleled source of information.
