First published in 1984. As scholar, researcher, and commentator, Dr. Paul E. Zinner has spent much of the last six years in Europe studying the development of East-West relations, observing negotiations on arms reduction, and conducting interviews with foreign policy and national security experts from key countries. This book brings together eleven of his essays~-nearly all previously unpublished--that emphasize developments since 1977. The essays cover a broad range of topics, among them the status and prospects of the Vienna troops reduction talks; the political and military implications of NATO's "double track" decision concerning modernization of intermediate-range nuclear forces in Europe; the impact of the crises in Afghanistan and Poland on the Western alliance; and the foreign policy options available to the Reagan administration. Also included are assessments of current trends in the NATO alliance and a cautious projection of the political climate in Western Europe by the end of the 198Os. Updated throughout with introductory and commentary notes, the essays provide insight into the dominant themes in the interaction between the NATO and Warsaw Pact powers.

The influence of Arabic-Islamic science on European astronomy is still evident in the number of terms and star names which derive from the Arabic. These articles examine what the Arabs - and other peoples of the Islamic world - knew about the fixed stars and the constellations, and the astrological traditions they associated with them. Professor Kunitzsch shows how the early folk astronomy of the Arabs was radically altered, without being swept away, by the discovery of ancient Greek, also Indian and Persian, sources; by far the most important of these was the Almagest of Ptolemy. This knowledge was then transmitted to medieval Europe, to Byzantium and, especially, to Spain, as the articles go on to describe, and was a vital factor in stimulating the development of scientific thought in the West.
The spallation neutron source (SNS) being built at the Oak Ridge National Laboratory (ORNL) will be by far the highest flux pulsed source of epithermal neutrons in the world when it comes on line in 2006. Although the main thrust of the science program at the SNS will be materials science, the facility could provide outstanding opportunities for research in nuclear astrophysics, fundamental symmetries, and applied nuclear physics. To review the current status of these fields and to begin to assemble the scientific case and the community of researchers for future experiments at the SNS, a workshop on ?Astrophysics, Symmetries, and Applied Physics? was held in March 2002 at the ORNL. Over 60 scientists, representing 11 US and 4 foreign universities as well as many national laboratories around the world, participated in the workshop. The proceedings describe the current state of research in those fields and the future opportunities at the SNS.
This work summarizes the historical progression of the field of lithium (Li) isotope studies and provides a comprehensive yet succinct overview of the research applications toward which they have been directed. In synthesizing the historical and current research, the volume also suggests prospective future directions of study. Not even a full decade has passed since the publication of a broadly inclusive summary of Li isotope research around the globe (Tomascak, 2004). In this short time, the use of this isotope system in the investigation of geo- and cosmochemical questions has increased dramatically, due, in part, to the advent of new analytical technology at the end of the last millennium. Lithium, as a light element that forms low-charge, moderate-sized ions, manifests a number of chemical properties that make its stable isotope system useful in a wide array of geo- and cosmochemical research fields.
This brand new edition describes in detail the tests involved in urodynamic investigation and shows in which clinical areas these tests can help the management of patients. The authors concentrate on common clinical problems and on the presentation of symptom complexes rather than diagnosis, pointing out any limitations and possible artefacts of investigation. * The new edition takes into account the technological innovations that have taken place over the last 10 years, while retaining the original objectives of the first edition. * The subject is presented so simply that a clinician with no previous experience will learn how to use the appropriate equipment in the correct situation. * Urodynamic investigation is described in such detail that it can be accepted in its own right as a fundamental contribution to the management of many patients. After reading this book, clinicians will appreciate the value and limitations of the subject and will have obtained the necessary practical advice on which equipment to use in which situation.
Paul Feyerabend's globally acclaimed work, which sparked and continues to stimulate fierce debate, examines the deficiencies of many widespread ideas about scientific progress and the nature of knowledge. Feyerabend argues that scientific advances can only be understood in a historical context. He looks at the way the philosophy of science has consistently overemphasized practice over method, and considers the possibility that anarchism could replace rationalism in the theory of knowledge. This updated edition of the classic text includes a new introduction by Ian Hacking, one of the most important contemporary philosophers of science. Hacking reflects on both Feyerabend's life and personality as well as the broader significance of the book for current discussions.
If you want to know where you are, you need a good clock. The surprising connection between time and place is explored in Time and Navigation: The Untold Story of Getting from Here to There, the companion book to the National Air and Space Museum exhibition of the same name. Today we use smartphones and GPS, but navigating has not always been so easy. The oldest "clock" is Earth itself, and the oldest means of keeping time came from observing changes in the sky. Early mariners like the Vikings accomplished amazing feats of navigation without using clocks at all. Pioneering seafarers in the Age of Exploration used dead reckoning and celestial navigation; later innovations such as sextants and marine chronometers honed these techniques by measuring latitude and longitude. When explorers turned their sights to the skies, they built on what had been learned at sea. For example, Charles Lindbergh used a bubble sextant on his record-breaking flights. World War II led to the development of new flight technologies, notably radio navigation, since celestial navigation was not suited for all-weather military operations. These forms of navigation were extended and enhanced when explorers began guiding spacecraft into space and across the solar system. Astronauts combined celestial navigation technology with radio transmissions. The development of the atomic clock revolutionized space flight because it could measure billionths of a second, thereby allowing mission teams to navigate more accurately. Scientists and engineers applied these technologies to navigation on earth to develop space-based time and navigation services such as GPS that is used every day by people from all walks of life. While the history of navigation is one of constant change and innovation, it is also one of remarkable continuity. Time and Navigation tells the story of navigation to help us understand where we have been and how we got there so that we can understand where we are going.
This book brings together the most up-to-date information on the fabrication techniques, properties, and potential applications of low dimensional silicon carbide (SiC) nanostructures such as nanocrystallites, nanowires, nanotubes, and nanostructured films. It also summarizes the tremendous achievements acquired during the past three decades involving structural, electronic, and optical properties of bulk silicon carbide crystals. SiC nanostructures exhibit a range of fascinating and industrially important properties, such as diverse polytypes, stability of interband and defect-related green to blue luminescence, inertness to chemical surroundings, and good biocompatibility. These properties have generated an increasing interest in the materials, which have great potential in a variety of applications across the fields of nanoelectronics, optoelectronics, electron field emission, sensing, quantum information, energy conversion and storage, biomedical engineering, and medicine. SiC is also a most promising substitute for silicon in high power, high temperature, and high frequency microelectronic devices. Recent breakthrough pertaining to the synthesis of ultra-high quality SiC single-crystals will bring the materials closer to real applications. Silicon Carbide Nanostructures: Fabrication, Structure, and Properties provides a unique reference book for researchers and graduate students in this emerging field. It is intended for materials scientists, physicists, chemists, and engineers in microelectronics, optoelectronics, and biomedical engineering.
In the past ten years, heteroepitaxy has continued to increase in importance with the explosive growth of the electronics industry and the development of a myriad of heteroepitaxial devices for solid state lighting, green energy, displays, communications, and digital computing. Our ever-growing understanding of the basic physics and chemistry underlying heteroepitaxy, especially lattice relaxation and dislocation dynamic, has enabled an ever-increasing emphasis on metamorphic devices. To reflect this focus, two all-new chapters have been included in this new edition. One chapter addresses metamorphic buffer layers, and the other covers metamorphic devices. The remaining seven chapters have been revised extensively with new material on crystal symmetry and relationships, III-nitride materials, lattice relaxation physics and models, in-situ characterization, and reciprocal space maps.
Central Europe - here, Poland, the German Democratic Republic, Czechoslovakia and Hungary - is at the centre of international attention since the Soviet collapse. An understanding of its postwar history is critical to an appreciation of the challenges facing its present rulers. This is an engrossing account of the installation, development, operation and eventual downfall of its (very different) communist regimes, and the transition to the freedoms and uncertainties of the post-Soviet world. The book covers political, economic, social and cultural change, emphasising the crucial relationships with the USSR throughout.
Renal sonography forms a basic part of routine diagnostic strategy. This textbook summarizes eighteen years of experience in diagnostic ultrasound. We want it to serve as a guide to both imagers and mere consumers of information. That is why we shall emphasize practical advice and diagnostic pitfalls; it is also why we shall often deal with the relations of sonography with other diagnostic procedures, which it may complement or replace, precede or follow, the purpose being to achieve efficiency at low cost. We shall limit our subject matter to the kidney itself and the neighboring retroperitoneal compartments, dealing only briefly with the lower urinary tract, which requires specialized procedures. We devoted considerable space to renal sonography in our book Clinical Atlas of Ultrasonic Radiography, published in 1973. Since then, nothing has changed and everything has changed. Nothing, because even then the differential diagnosis between a solid and a cystic mass, the etiologic diagnosis of a nonsecreting kidney, and the positive diagnosis of a traumatic juxtarenal hematoma were quite reliable, making possible drastic reductions in the indications for instrumental roentgenologic examinations. Everything, be cause improved resolution and grey scale imaging (already partially achieved in 1973, thanks to real time) have profoundly refined both anatomic and pathologic ultrasonic studies. And now high resolution real time imaging has revolutionized renal examination techniques, whereas Doppler is entering routine ultrasonic diagnosis.
Studying Captive Animals outlines the methods that may beused to study the behaviour, welfare and ecology of animals livingunder the control of humans, including companion animals, feralpopulations, and those living on farms and in zoos. This book is a step-by-step guide to the whole process ofconducting a scientific study: from designing the original project,formulating testable hypotheses, and collecting and analysing thedata, to drawing conclusions from the work and writing it up as ascientific report or paper. It also illustrates how to write aformal research proposal - a crucial and often difficult element ofthe student project - and how to deal with the ethical reviewprocess. Sample data collection sheets are provided and the analysis andpresentation of data are worked through in diagrammatic form. Inaddition, exercises are included that enable the reader to practice analysing different types of data and advice isprovided on the selection of appropriate statistical tests. Thetext describes the different types of student projects that may beundertaken in the field, and explains where secondary data may befound for zoos. This is an insightful resource, particularly for those studyingand working with zoo and farm animals. It is essential reading forstudents studying zoo biology and animal management; it is alsosuitable for students on courses in animal behaviour, animalwelfare, zoology, biology, psychology, animal science, animalproduction, animal ecology, conservation biology, and veterinaryscience. This book is primarily intended for undergraduates butwill also be of value to postgraduate students who have notpreviously engaged in field studies. Professionals working ininstitutions that are members of the World Association of Zoos andAquariums, the European Association of Zoos and Aquaria and otherregional and national zoo organisations will benefit from access tothis practical guide.
From Sean Connery to Roy Rogers, from comedy to political satire, films that include espionage as a plot device run the gamut of actors and styles. More than just "spy movies," espionage films have evolved over the history of cinema and American culture, from stereotypical foreign spy themes, to patriotic star features, to the Cold War plotlines of the sixties, and most recently to the sexy, slick films of the nineties. This filmography comprehensively catalogs movies involving elements of espionage. Each entry includes release date, running time, alternate titles, cast and crew, a brief synopsis, and commentary. An introduction analyzes the development of these films and their reflection of the changing culture that spawned them.
