For thousands of years, people of all cultures have made and used clocks, from the city sundials of ancient Rome to the medieval water clocks of imperial China, hourglasses fomenting revolution in the Middle Ages, the Stock Exchange clock of Amsterdam in 1611, Enlightenment observatories in India, and the high-precision clocks circling the Earth on a fleet of GPS satellites that have been launched since 1978. Clocks have helped us navigate the world and build empires, and have even taken us to the brink of destruction. Elites have used them to wield power, make money, govern citizens, and control lives-and sometimes the people have used them to fight back. Through the stories of twelve clocks, About Time brings pivotal moments from the past vividly to life. Historian and lifelong clock enthusiast David Rooney takes us from the unveiling of al-Jazari's castle clock in 1206, in present-day Turkey; to the Cape of Good Hope observatory at the southern tip of Africa, where nineteenth-century British government astronomers moved the gears of empire with a time ball and a gun; to the burial of a plutonium clock now sealed beneath a public park in Osaka, where it will keep time for 5,000 years. Rooney shows, through these artifacts, how time has been imagined, politicized, and weaponized over the centuries-and how it might bring peace. Ultimately, he writes, the technical history of horology is only the start of the story. A history of clocks is a history of civilization.

Ecological Assessment of Polymers Strategies for Product Stewardship and Regulatory Programs John D. Hamilton and Roger Sutcliffe The expense of providing ecological assessments of new commercial products is formidable. The cost of the failure to comply with the current regulations--measured in fines, liability damages, and loss of public trust--is potentially much, much higher. Establishing effective environmental product stewardship strategies for assessment upfront not only promotes initial and continued compliance, it can reduce costs via the more efficient development of new products. Based on the collaboration of the Rohm and Haas Company and S.C. Johnson Wax with other manufacturers, contract laboratories, universities, and government agencies, Ecological Assessment of Polymers is the first complete reference to provide environment-oriented information about polymers from a product development and regulatory compliance perspective. A number of books deal with the potential hazards of pesticides and solvents. This is the first to focus on the commercial synthetic polymers that exist in laundry detergents, paints, super-absorbent diapers, packaging materials, and many other consumer and industrial products. Using the principles of environmental toxicology and chemistry, Ecological Assessment of Polymers approaches environmental evaluation as a decision-making process. The book demonstrates how assessment can be used as a planning tool for developing products, reducing potential liability, and creating new products, processes, and disposal systems. Featured discussions:

• Overviews of methods, instrumentation, and databases used by environmental scientists to assessprocesses/products involving polymers
• Environmental regulatory assessment schemes for preventing dangerous environmental exposure during manufacture, use, transport, storage, and disposal
• Interpretations of ecotoxicity and fate tests with polymers
• New directions of research in degradable polymers
• Life-Cycle Assessment (LCA) of polymers
• Polymer regulations from the United States, Canada, Europe, and the Pacific Region

From the Author's Preface
Ceramic sensors have been in use for more than thirty years. Since ceramics exhibit a number of specific characteristics that enable their cost to become lower and their reliability to increase, they have occupied a significant position in sensor technology. This is why many companies and universities have directed their efforts towards investigating and developing new ceramic sensors and expanding their areas of application.
To the best of our knowledge.., there has been] no book treating different sensors on the basis of their common physical and chemical properties, technological principles, and applications. This book is] a detailed survey of ceramic sensors and a generalization of the results achieved in this field so far. Ceramic sensors for different physical quantities are discussed without going too deep into theory...
The concept of ceramic sensors includes all sensors that are produced using ceramic technology. It also covers thick film sensors, since from a structural and technological point of view, they can be regarded as a variety of ceramic sensors. The subject of scientific research in this book is humidity, gas. temperature, and pressure sensors on the basis of semiconductor and dielectric ceramic materials and solid electrolytes.
Special attention is paid to the physical and chemical, as well as the technological, bases of ceramic sensors, their classification, the types of materials used..., the methods of controlling their parameters and characteristics, the areas of application, and the electric circuits for connecting the sensors.

Techniques and Topics in Flow Measurement covers the applications and techniques of flow measurement. This definitive book provides guidelines for choosing appropriate techniques and assuring valid measurements as well as describes methods for treatment of calibration data in fluid flow under various conditions. The book also covers three systems of units: the SI system, the English Absolute Dimensional system, and the English Engineering system. Commonly used - and often misused - variables such as force, weight, and pressure are defined, and the relationships between the systems for these common variables are summarized.
One of the many unique features of Techniques and Topics in Flow Measurement is the number of ready-to-use tables included throughout the text. Tables are provided for such commonly encountered variables as the saturation vapor pressure of water; the composition of dry air; the compressibility factor for air; air-free and air-saturated water density; viscosity of dry air, nitrogen, and other gases; and specific heat/specific volume ratios for dry air, water vapor, and moist air. Another unique feature of this book is the number of highly relevant examples. The author includes examples/exercises that demonstrate applications for density calculations; water vapor mixing ratio determination; gas viscosity interpolation; NIST guideline applications; buoyancy corrections; and more.

This book is the first to present flow measurement as an independent branch of the measurement techniques, according to a new global and unitary approach for the measurement of fluid flow field, starting from finding its unitary fundamental bases. Furthermore, it elaborates the method of unitary analysis/synthesis and classification of compound gauging structures (CGS): the UASC - CGS method. These methods ensure, in a systematic and predictable way, both the analysis of the types of flow meters made until present (i.e. CGS) and the synthesis of new types of flowmeters. The book outlines new contributions in this field, including separately, for flow meters, and CGS: structural schemes and their unitary, unitary classification, unitary logical matrix, method of unitary analysis/synthesis and classification.

Can the newborn infant accurately record traumatic experience? Can early traumas be retained in memory? How would such traumatic memories affect later development? Where should we look for evidence of such traumas in adult patients? If Someone Speaks, It Gets Lighter provides surprising answers to these questions. Taking as her point of departure both her own clinical experience and case reports in the analytic literature, Lynda Share provides a thorough, at times revelatory, examination of the basic issues. She proposes that the controversy between narrative and historical truth be redefined in terms of the distinctly different memory systems involved and in terms of the special mechanisms whereby trauma, as opposed to ordinary expectable experience, becomes a major unconscious organizer of behavior and memory. Then, winding her way skillfully through contemporary debates about the limits of reconstruction, she argues persuasively that the impact of early infantile trauma can become accessible through disciplined analytic inquiry. Indeed, for Share, to forego the possibility of reconstructing such traumas in favor of an exclusively here-and-now interpretive approach is to risk perpetuating the trauma in all its pathogenicity. By contrast, when trauma can be reexperienced meaningfully in treatment, both behavioral reenactments and trauma-related transference issues can be dramatically clarified. Demonstrating her point with vivid clinical case reports, Share emphasizes the special value of dream interpretation in recovering the full psychological impact of events that occurred in the first few years of life. Through the imagistic dimension of dream formation, unconscious traumaticmemories gain access to an expressive vehicle through which the patient, aided by the analyst's understanding, can begin to work through early experiences that have heretofore been dimly known but not felt. At once a return to the intuitions of the early psychoanalytic pioneers and a foray into the recent insights of developmental psychology, If Someone Speaks, It Gets Lighter integrates scientific research with contemporary psychoanalytic theory to reclaim an important area of therapeutic intervention. Specifically, Share's framework enables analysts and therapists to realize the clinical imperative of helping patients move beyond the unconscious limits laid down by their earliest histories.
