Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The first part of this title contained all statistical tests relevant to starting clinical investigations, and included tests for continuous and binary data, power, sample size, multiple testing, variability, confounding, interaction, and reliability. The current part 2 of this title reviews methods for handling missing data, manipulated data, multiple confounders, predictions beyond observation, uncertainty of diagnostic tests, and the problems of outliers. Also robust tests, non-linear modeling , goodness of fit testing, Bhatacharya models, item response modeling, superiority testing, variability testing, binary partitioning for CART (classification and regression tree) methods, meta-analysis, and simple tests for incident analysis and unexpected observations at the workplace and reviewed. Each test method is reported together with (1) a data example from practice, (2) all steps to be taken using a scientific pocket calculator, and (3) the main results and their interpretation. Although several of the described methods can also be carried out with the help of statistical software, the latter procedure will be considerably slower. Both part 1 and 2 of this title consist of a minimum of text and this will enhance the process of mastering the methods. Yet the authors recommend that for a better understanding of the test procedures the books be used together with the same authors' textbook 'Statistics Applied to Clinical Studies' 5th edition edited 2012, by Springer Dordrecht Netherlands. More complex data files like data files with multiple treatment modalities or multiple predictor variables can not be analyzed with a pocket calculator. We recommend that the small books 'SPSS for starters', Part 1 and 2 (Springer, Dordrecht, 2010, and 2012) from the same authors be used as a complementary help for the readers' benefit. 88 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In recent years there has been a rapid increase in the understanding of communication between animals and this is perhaps especially true of bio-acoustics. In the last 35 years a completely new branch of bio acoustics, involving ultrasounds, has been made possible by technical developments that now allow these inaudible sounds to be detected and studied. This subject has a personal fascination for the authors, perhaps because of the novelty of 'listening in' to these previously unknown sig nals, perhaps because of the wide variety of ways in which different animals use them. Many studies of different aspects of animal ultrasound have now been published and a review of them all seems to be timely. Ultrasound is is biologically arbitrary; other animals defined in human terms and may produce similar signals at lower frequencies for similar purposes. This book attempts to be comprehensive but the limits of the subject are rather difficult to define. It should be read in conjunction with other books on audible bio-acoustics. Each chapter has been written and may be read as a separate entity, although there is considerable cross-referencing. Chapters 1 and 2 form a common introduction and may help in understanding the later sections. The Appendix is not essential but is included for those who may be interested in the quanti tative aspects of the echo-location phenomena described in Chapters 3 and 8. 324 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book documents research conducted on the analysis of urban growth and sprawl by using remote sensing data and GIS techniques. The research was conducted between 1980-2010 in the city of Kolkata, India. The aim of the research was to use metrics that were less demanding in terms of data and computation than normal metrics. However, it has been found that most of them were inferior in capturing insights of urban sprawl. For this book, some of these metrics have therefore been modified and new ones are proposed. The research focuses on problems associated with the analysis of urban growth by using remote sensing data from a technological perspective. 120 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Obesity in affluent countries continues to be a serious problem. When one runs an Obesity Clinic there appears to be an unending series of patients who need help. Our understanding of weight control has been advanced not only by the studies of obese patients but also by our investigation of the problems of weight gain in young women with anorexia nervosa. Just as among obese patients there is the group of 'efficient metabolizers' who can maintain their excessive weight with a calorie intake occasion ally as low as 600 kcal per day, so we have demonstrated that among anorexic women there are a few who may fail to gain normal weight with 3500 kcal per day. Some of the latter group may in fact develop T3 (tri-iodothyronine) thyrotoxicosis. One of the major unknown factors is still what determines when patients may be at these extremes. If we knew how to control these extremes we would like, for a time, to switch each to the opposite end of the spectrum. One factor which is becoming apparent from studying people in the machine which continually plots metabolic rate is that the metabolic response to food is a' major factor in determining a person's weight. In general terms there is a tendency for those who are below their ideal weight to have an increased metabolic response to food and those who are above ideal weight to have a reduced metabolic response to food. 124 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This text is an introduction to the physics of collisional plasmas, as opposed to plasmas in space. It is intended for graduate students in physics and engineering . The first chapter introduces with progressively increasing detail, the fundamental concepts of plasma physic. The motion of individual charged particles in various configurations of electric and magnetic fields is detailed in the second chapter while the third chapter considers the collective motion of the plasma particles described according to a hydrodynamic model. The fourth chapter is most original in that it introduces a general approach to energy balance, valid for all types of discharges comprising direct current(DC) and high frequency (HF) discharges, including an applied static magnetic field. The basic concepts required in this fourth chapter have been progressively introduced in the previous chapters. The text is enriched with approx. 100 figures, and alphabetical index and 45 fully resolved problems. Mathematical and physical appendices provide complementary information or allow to go deeper in a given subject. 504 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Disorder is everywhere, inherently present in nature, and is commonly believed to be a synonymous with disturbance. As a consequence, the methodical and customary study of the dynamics of the electromagnetic field, both in the linear and nonlinear optical regimes, leans to rule out it from the treatment. On the other hand, nonlinearity enriches the physical disciplines and brings them closer to reality with respect to the linear approximation. Nonlinearity allows to stimulate a wide and rich ensemble of optical responses that beautifies the role of matter in the active processes with electromagnetic fields. Independently of each other, both of these mechanisms foster localization of light. What happens when light enlightens their synergistic interaction When pushed together, light, disorder and nonlinearity make new and intriguing phenomena emerge. This text provides a comprehensive investigation of the role of disorder in the nonlinear optical propagation both in transparent media and lasers. Eventually, disorder promotes and enhances complex nonlinear dynamics opening new perspectives in applied research driven by the processes of localization of the electromagnetic field. The first experimental study of laser emission in granular media unveils how randomness magnifies and largely affect laser-matter interactions. Viola Folli in her research work touches and deepens the leading milestones of the new science named Complex Photonics. 132 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is derived from a series of articles written for dental practitioners and first published in Dental Update. The articles were written as a consequence of running a weekly clinic, concerned largely with the correction of referred endodontic problems. In most cases the 'problems' did not exist and were treated simply by redoing the root filling or by undertaking a straightforward apicectomy. Regrettably, in many other cases, the problem would not have existed had the previously undertaken, and potentially simple, apicectomy been carried out competently. There is no good reason why apical surgery should not be undertaken by the general dental practitioner as part of the patient's overall treatment. After all, the problem will usually have arisen either during, or as a result of, routine dental treatment. In addition, the tooth may require to be restored, either at the time of surgery or fairly soon thereafter. Regrettably, inexperience in the handling of soft tissues, and concern about the risk of damage to associated structures, often deters the dentist from attempting what is, if sensibly approached, an uncomplicated minor dento-alveolar operation. Chapters 1-8 introduce the reader to the basic techniques of apicectomy. Chapters 9, 12, 16 and 17 will, it is hoped, help the interested dentist to develop a competence to treat more complex cases, once he or she has become proficient in the basic skills. 120 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Catalysis involves just about every field of scientific study. This means that a multidisciplinary approach is needed in catalytic studies. Catalysis involves breaking and forming new bonds and this requires an under standing of either adsorption by bonding to an extended structures or bonding in a coordination sphere. Any understanding of catalytic action must necessarily involve an understanding of this bonding. Even 200 years ago scientists were aware that a properly treated mate rial, such as charcoal, could adsorb an enormous quantity of gas. In 1812, de Sassasure (English translation, Annal Philosphy, 6, 241 (1815' pro posed that the ability of a material to increase the rate of chemical reac tion was due to adsorption of the material in the fine structure of the solid so that the concentrations of the reactants were significantly increased, and this increase in concentration led to an increase in reaction rate. During the 1800s, little advance was made in the understanding of adsorp tion. 552 pp. Englisch.

We. the fortunate from the haemophilia oasis. have much to learn from each other. This is important. but even more important is the urgency to convey your knowledge. your skills. your experience and your dedication to the haemophiliacs in the desert: 'We can only begin to understand the condition. the life of a sufferer. by comparing him to a soldier in the trenches of World War I. In the trenches the soldier seldom forgets that the next moment may bring death or crippling. The haemophiliac is literally in the trenches. The soldier may be spared injury. but pain awaits the haemophiliac. Fear. moreover, is paramount to the pain. As in the trenches. the anxiety can be more oppressive than the wound. Waiting to go over the top imposes a greater strain than the actual charge. For the soldiers that survived World War I in the trenches. 4 years seemed eternity; the haemophiliac never leaves the battlefield: Opening Address, Frank Schnabel. World Federation of Hemophilia. Copenhagen. June 25th. 1963. War can come to an oasis, peace can come to the trenches. With this book, Dr Peter Jones has joined the international struggle. Carefully, concisely and cogently. the text offers a grand strategy. With allies like Dr Jones we will, one day, achieve victory. Frank Schnabel, Chairman. 188 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This booktouches upon a few of the major challenges that all modern societies will have to face in the near future: how to set up a resilient pay-as-you-go pension system; whether the current balance between expenses and revenues in social expenditure is viable in the future, and, if not, what changes need to be introduced; whether the relative well-being of the current and future cohorts of the old will be preserved, and how their standards of living compare to those experienced by the old in the recent past.At the micro level, the exchanges between generations are presented and discussed in detail: how they have evolved in the recent past in terms of time, money, co-residence and proximity, and what will likely happen next. The geographical scope is on the developed countries, plus South Korea.A rich documentation of tables and graphs supports the scientific analyses and the policy implications in each of the nine chapters of this book, where demography, sociology, and economics intersect fruitfully, both at the macro and at the micro level. 224 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Trace metals occur as natural constituents of the earth's crust, and are ever present constituents of soils, natural waters and living matter. The biological significance of this disparate assemblage of elements has gradually been uncovered during the twentieth century; the resultant picture is one of ever-increasing complexity. Several of these elements have been demonstrated to be essential to the functions of living organisms, others appear to only interact with living matter in a toxic manner, whilst an ever-decreasing number do not fall conveniently into either category. When the interactions between trace metals and plants are considered, one must take full account of the known chemical properties of each element. Consideration must be given to differences in chemical reactivity, solubility and to interactions with other inorganic and organic molecules. A clear understanding of the basic chemical properties of an element of interest is an essential pre-requisite to any subsequent consideration of its biological significance. Due consideration to basic chemical considerations is a theme which runs through the collection of chapters in both volumes. 272 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Chapter I describes deposition as a basic microelectronics technique. Plasma enhanced chemical vapor deposition (PECVD) is a technique widely accepted in microelectronics for the deposition of amorphous dielectric films such as silicon nitride and silicon oxide. The main advantage of PECVD stems from the intro duction of plasma energy to the CVD environment, which makes it possible to promote chemical reactions at relatively low temperatures. A natural extension of this is to use this plasma energy to lower the temperature required to obtain a crystalline deposit. This chapter discusses the PECVD technique and its ap plication to the deposition of dielectric, semiconductor, and conductor films of interest to microelectronics. Chapter 2 acquaints the reader with the technology and capabilities of plasma processing. Batch etching reactors and etching processes are approaching ma turity after more than ten years of development. Requirements of anisotropic and selective etching have been met using a variety of reactor configurations and etching gases. The present emphasis is the integration of plasma etching processes into the overall fabrication sequence. Chapter 3 reviews recent advances in high pressure oxidation technology and its applications to integrated circuits. The high pressure oxidation system, oxi dation mechanisms, oxidation-induced stacking faults, impurity segregation, and oxide quality are described. Applications to bipolar and MOS devices are also presented. 960 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is traditional in the literature on Pierre Bayle to make some refer ene e to iVlontaigne as one of the masters of skepticism in whose tracks he follows, albeit hardly so eloselyas Charron had. Time and again critics feel the need to mention Montaigne and Bayle in the same context, sometimes to contrast their brands of Pyrrhonism, more often to explain similarities in their ideas and methods, which have frequent ly been regarded as important steps in the gradual evolution of un Christian, even anti-Christian, thought. Their names were already associated during Bayle's life, for example, in the mediocre work by Dom Alexis Gaudin, La Distinction et la Nature du Bien et du MaI, Traite ou l'on combat l'erreur des Manicheens, les sentimens de Jvfontaigne & de Charron, & ceux de J. Vfonsieur Bayle. In the nineteen th century, the author of the Dictionnaire historique et critique wa~ generally elassified as a skeptic; and his name was inevi tably linked with the essayist's. In his Port-Royal, Sainte-Beuve pictured Bayle as one of the avowed skeptics in Montaigne's funeral cortege and spoke of both men as 'd'autant pIus fourbes qu'ils ne le sont pas toujours. ' His later works show that he revised his opinion on each somewhat,l but in this he was unusual for his century. 376 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Semiconductors have been used widely in signal-level or 'brain' applications. Since their invention in 1948, transistors have revolutionized the electronics industry in computers, information processing, and communications. Now, however, semiconductors are being used more and more where consid erable 'brawn' is required. Devices such as high-power bipolar junction tran sistors and power field-effect transistors, as well as SCRs, TRlACs, GTOs, and other semiconductor switching devices that use a p-n-p-n regenerative effect to achieve bistable action, are expanding the power-handling horizons of semicon ductors and finding increasing application in a wide range of products including regulated power supplies, lamp dimmers, motor drives, pulse modulators, and heat controls. HVDC and electric-vehicle propulsion are two additional areas of application which may have a very significant long range impact on the tech nology. The impact of solid-state devices capable of handling appreciable power levels has yet to be fully realized. Since it first became available in late 1957, the SCR or silicon-controlled rec tifier (also called the reverse blocking triode thyristor) has become the most popular member of the thyristor family. At present, SCRs are available from a large number of manufacturers in this country and abroad. SCR ratings range from less than one ampere to over three thousand amperes with voltage ratings in excess of three thousand volts. 340 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is a privilege to be asked to introduce this important work. Such a book has long been needed. Industrial manipulators and robots have caught the attention of the general public and become very fashionable in the last few years. The casual reader of current newspapers and magazit:les or the viewer of television and films might easily conclude that the development of mechanical hands, arms and legs or other mobility devices has progressed rapidly in only the last few years. Most people are unaware of the gradual orderly succession of creative designs and painstaking refinements which have been produced over a greater number of years. That story is carefully described in this volume, together with diagrams and photographs which document in detail this elegant phase in the history of machine design. This volume together with Volume 3A constitute the most complete and comprehensive work on manipulators and teleoperators. Jean Vertut and Philippe Coiffet are well known not only as authors but also as engineers who have produced some of the finest devices in the world. Of course for the complete history of manipulators and teleoperators one must look back to the artisans who crafted the delightful clock works, mechanical puppets and toys before and during the Renaissance. 260 pp. Englisch.

Harris presented the first three chapters of Atheism and Theism as public lectures at Tulane University on January 20-22, 1975. The lecture series was made possible by a grant from the Franklin J. Matchette Foundation of New York City. Those of us who had the pleasure of hearing the lectures formed the judgment that they deserved publication to reach a wider audience and to assure a more permanent reeord. We invited Professor Harris to allow us to publish his lectures in Tulane Studies in Philosophy. On his part, he de veloped the themes of the lectures into a more comprehensive and lasting work. With Professor Harris's approval, we are taking the unprecedented step of devoting Volume XXVI of Tulane Studies in Philosophy to the publication of Atheism and Theism. We are certain that it will advance the fundamentally philosophical argument surrounding theism and Christianity. We are also convinced that it will add substantialIy to the prestige of our series of annua1 volumes of philosophy, now in its twenty-sixth year. 'Ve wish to express our thanks to the Franklin J. Matchette Foundation for the original grant sup porting the lectures and to Professor Harris for presenting first the lectures and then the book. R. C. W. A. J. R. 172 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Only 14 years have passed since the first publication appeared which implicated mycoplasmas as agents of plant disease. The diseases them selves have been known for much longer; indeed clover phyllody, a typical example, was described in the seventeenth century, well before any animal mycoplasma diseases had been documented. The early history of plant mycoplasmas is described in Chapter 2 and one obvious conclusion to be drawn from the frustrating experiences of the earlier workers is that the experimental methods at their disposal were simply inadequate for the task. Progress in science depends critically upon the development of new methods. Although important advances have been made in plant and insect mycoplasmology, notably in the discovery of spiroplasmas, many intractable problems remain. Most plant myco plasmas cannot yet be cultured in vitro, and their natural plant habitat, the phloem, is one of the most difficult plant tissues for the experi menter to handle, placing severe restrictions on the type of experiments which can be performed in vivo. It is clear that radically new methods may be required to solve these problems. A survey of the progress which has been made shows that application of techniques from a wide range of disciplines has been necessary. A successful individual or group of workers must possess the skills of a plant pathologist, a plantsman, a plant physiologist, a light-and electron microscopist, a bacteriologist, a biochemist, an immunologist, an ento mologist, a virologist and a molecular geneticist. 372 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume reviews the most recent knowledge in the field of gastrointestinal motility in health and disease. The topics addressed include basic as well as clinical data concerning the motor functions of the entire gut: the lower oesophageal sphincter and the gastro-oesophageal reflux; the gastric emptying and the role of the pylorus; the motility of the biliary tract and its disorders; the cyclic motor activity of the gut and intestinal transit; the colonic and ano-rectal motility. There are also impOltant contributions in physiology and pharmacology relating to the neurohumoral regulation of the gut, and the function of digestive smooth muscle. Several papers explore the nature of the linkage between brain and gut. a link which has long been deduced by clinicians but not, until recently, systematically explored by scientists. The individual papers, selected from a large number of submissions, have been subject to 'peer-review' by an inter national committee which includes both cliniCians and basic scientists. Therefore this book should serve as an up to date source of information for researchers concerned with basic sciences as well as for clinicians in gastroenterology, medicine and surgery. C.

This item is printed on demand - it takes 3-4 days longer - Neuware -Kilbourne (1973) described the student of influenza as 'continually looking back over his shoulder and asking 'what happened ', in the hope that understanding of past events will alert him to the catastrophies ofthe future'. Experience suggests the futility of such a hope, since the most predictable feature of influenza is its unpredictability. Nonetheless, the stubborn viabil ity of this hope is strongly affirmed by the many attempts, described and discussed in this volume, to develop a useful and practical representation of influenza virus behavior. I hasten to add, however, that the desired model has yet to be perfected. The existence and usefulness of animal models of infectious diseases of man are well documented. Reproduction of disease by infecting an experimental animal satisfies the third of Koch's four postulates to establish proof of disease causation by a specific bacterium. Animal models also have been extremely useful in studies of the pathogenesis, immunoprophylaxis, and specific therapy of several important diseases, ineluding (with only modest success) influenza. Development of such a model is simple, at least in concept. and can be achieved by one or only a few scientists. 260 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Geometric Methods in System Theory In automatic control there are a large number of applications of a fairly simple type for which the motion of the state variables is not free to evolve in a vector space but rather must satisfy some constraints. Examples are numerous; in a switched, lossless electrical network energy is conserved and the state evolves on an ellipsoid surface defined by x'Qx equals a constant; in the control of finite state, continuous time, Markov processes the state evolves on the set x'x = 1, xi ~ O. The control of rigid body motions and trajectory control leads to problems of this type. There has been under way now for some time an effort to build up enough control theory to enable one to treat these problems in a more or less routine way. It is important to emphasise that the ordinary vector space-linear theory often gives the wrong insight and thus should not be relied upon. 324 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Let us then consider, for a moment, the world as described by the physicist. It consists of a number of fundamental particles which . appear bound by certain natural laws which indicate the form of their relationship_ Now the physicist himself who describes all this, is in his own account, himself constructed of it. He is, in short, made of a conglomeration of the very particulars he describes, no more, no less, bound together by and obeying such general laws as he himself has managed to find and to record. Thus we cannot escape the fact that the world we know is constructed in order (and thus in such a way as to be able) to see itself. This is indeed amazing. Not so much in view of what it sees, although this may appear fantastic enough, but in respect of the fact that it can see at all. But in order to do so, evidently it must first cut itself up into at least one state which sees and at least one other state which is seen. In this severed and mutilated condition, what ever sees is only partially itself. We may take it that the world undoubtedly is itself (i.e., is indistinct from itself), but, in any attempt to see itself as an object, it must, equally undoubtedly, act so as to make itself distinct from, and therefore false to, itself. In this condition it will always partially elude itself. 208 pp. Englisch.

Some of these variations can be measured, such as weight and length. Others are less easily measured, but have come to be recognized as common variants such as molding of the head or temporary deformations of limbs caused by unusual intrauterine positions. One way to recognize deviations from normal that may require intervention is to have a long experience examining many infants. Another way is to enrich a finite experience by access to a superb collection of photographs taken over a long period by a careful observer. No one student can possibly see all the normal and abnormal variations in newborn infants in the time allotted in most curricula, or for that matter in a lifetime. We are dependent on shared information. 424 pp. Englisch.

Sixty-three carefully chosen profes sionals were invited to participate in this institute together with 12 lecturers and 7 assistants. The 63 participants were selected from a group of almost 140 applicants. Each had the background to learn effectively the set of computer IC design aids which were presented. Each also had individual expertise in at least one of the topics of the Institute. The Institute was designed to provide hands-on type of experience rather than consisting of solely lecture and discussion. Each morning, detailed presentations were made concerning the critical algorithms that are used in the various types of computer IC design aids. Each afternoon a lengthy period was used to provide the participants with direct access to the computer programs. In addition to using the programs, the individual could, if his expertise was sufficient, make modifications of and extensions to the programs, or establish limitations of these present aids. The interest in this hands-on activity was very high and many participants worked with the programs every free hour. The editors would like to thank the Direction of SOGESTA for the excellent facilities, ~1r. R. Riccioni of the SOGESTA Computer Center and Mr. 11. Vanzi of the University of Genova for enabling all the programs to run smoothly on the set date. P.Antognetti D.O.Pederson Urbino, Summer 1980. 552 pp. Englisch.

I offer as evidence the spirited debates among scientists that have occurred in the past and that will probably continue for some time to come. Consider also that hypertension is a disease of significant morbidity and mortality, yet in the majority of instances the cause of the pressure elevation is unknown. And further, the wide variety of antihypertensive drugs currently used, often without a full understanding of the mechanisms involved, suggests that we often know as little about what decreases blood pressure with antihypertensive therapy as we know about what increases pressure in the first place. This ignorance has fostered and probably justified extensive inquiries into outstanding problems of blood pressure control. The pace has quickened in the last one or two decades, and published reports germaine to the subject appear to be accumulating at an exponential rate. Hence, speaking for myself, the reviewer is faced with too little understanding and too much information. 260 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The past few years have seen the publication of a large number of articles and not a few books on the subject of relief of intractable pain. New ideas have been put forward on pain mechanisms, new methods of treatment have been reported and improved results c1aimed, and a growing catalogue of complications oftreatment has been recorded. The vast and expanding literature on the subject poses for the reader the dual problems of surveil lance and of assessment. The object of the present book is to provide a critical and constructive review of current writings and ideas on a wide range of aspects of the nature of intractable pain, particularly of present day practice and new ideas on treatment. Each chapter is written by an acknowledged authority and the approach throughout is practical rather than academic. In editing the individual chapters an effort was made to achieve a contemporary approach and to eliminate material which was unduly historicalor retrospective in content. At the same time the individ ual style of the authors was retained as far as possible. For decades chronic pain has been a therapeutic 'no man's land'. For the surgeon pain was an unfortunate complication wh ich not infrequently followed surgery; for the physician it was a distressing symptom in a number of disease syndromes; to the psychiatrist it was one of a number of features in many cases of mental illness. 272 pp. Englisch.
