Cryptosporidium as a Foodborne Pathogen (SpringerBriefs in Food, Health, and Nutrition)
by Lucy J. RobertsonAlthough widely recognized as an important waterborne pathogen, Cryptosporidium spp. can also be transmitted by contamination of food. The same properties of this protozoan parasite that mean that water is an excellent transmission vehicle are also important for foodborne transmission. These include the low infective dose, the high number of oocysts that are excreted, and the robustness of these transmission stages. However, many more outbreaks of waterborne cryptosporidiosis have been reported than foodborne outbreaks. This is probably partly due to epidemiological tracing being much more difficult for foodborne outbreaks than waterborne outbreaks, and the number of persons exposed to infection often being fewer. Nevertheless, the potential importance of foodborne transmission is gradually being recognized, and a wide range of different foodstuffs have been associated with those outbreaks that have been recorded. Additionally, various factors mean that the potential for foodborne transmission is becoming of increasing importance: these include the growth of international food trade, a current trend for eating raw or very lightly cooked foods, and the rise in small-scale organic farms, where there the possibility for contamination of vegetable crops with animal feces may be greater.
Crystal Fire: The Invention Of The Transistor And The Birth Of The Information Age
by Michael Riordan Lillian Hoddeson"Without the invention of the transistor, I'm quite sure that the PC would not exist as we know it today."—Bill Gates On December 16, 1947, John Bardeen and Walter Brattain, physicists at Bell Laboratories, jabbed two electrodes into a sliver of germanium. The power flowing from the germanium far exceeded what went in; in that moment the transistor was invented and the Information Age was born. No other devices have been as crucial to modern life as the transistor and the microchip it spawned, but the story of the science and personalities that made these inventions possible has not been fully told until now. Crystal Fire fills this gap and carries the story forward. William Shockley, Bell Labs' team leader and co-recipient of the Nobel Prize with Brattain and Bardeen for the discovery, grew obsessed with the transistor and went on to become the father of Silicon Valley. Here is a deeply human story about the process of invention — including the competition and economic aspirations involved — all part of the greatest technological explosion in history. The intriguing history of the transistor — its inventors, physics, and stunning impact on society and the economy — unfolds here in a richly told tale."—Science News "Thoroughly accessible to lay readers as well as the techno-savvy. . . .

Crystal Structure,Electronic and Optical Properties of Epitaxial Alkaline Earth Niobate Thin Films (Springer Theses)
by Dongyang WanThis impressive thesis offers a comprehensive scientific study of the alkaline earth niobates and describes their nonlinear optical properties for the first time. It explores the crystal structure, electrical properties, optical absorption properties, hot carrier dynamics, nonlinear optical property and strain-induced metal to insulator transition of alkaline earth niobates using advanced experimental techniques. These alkaline earth niobates can have a strong plasmon resonance in the visible range due to their large carrier density, and this unique property gives rise to the emergent phenomenon of photocatalysis and nonlinear optical properties. This series of intrinsic plasmonic materials based on niobates, can be used as a photocatalyst to split water under sunlight, a novel saturable absorber in the high-power ultrashort pulsed laser system, and as a sensor in microelectromechanical systems.
Crystalline Lasers: Physical Processes and Operating Schemes
by Alexander KaminskiiBy the end of the 1970s, crystalline lasers were widely used in science, engineering, medicine, and technology. The types of lasers used have continued to grow in number to include newly discovered crystalline hosts, previously known compounds generating at other spectral wavelengths, and broadband tunable stimulated emission. This has led to the creation of an extremely promising new generation of crystalline lasers that are both highly efficient and more reliable. The major part of this book is devoted to describing multilevel operating laser schemes for stimulated emission excitation in insulating crystals doped with lanthanide ions.The first part of Crystalline Lasers deals with the history of the physics and spectroscopy of insulating laser crystals. The chapters in the second part of the book present results from the study of Stark-energy levels of generating ions in laser crystals and their radiative and nonradiative intermanifold transition characteristics. This section includes extensive tabular data and reference information. Popular and novel operating schemes of crystalline lasers are covered in Part 3.In the chapters in the fourth part of the book, the newest technologies in the physics and engineering of crystalline lasers are considered. The results of investigations into laser action under selective excitations, miniature crystalline lasers, and the properties of nonlinear activated laser crystals are presented and analyzed.Crystalline Lasers summarizes and reviews the results of many years of research and studies of activator ions and multilevel operating laser schemes, and discusses exciting prospects of using these systems to create new types of crystalline lasers. This book will be of use to laser scientists and engineers, physicists, and chemical engineers.

Crystallization Modalities in Polymer Melt Processing: Fundamental Aspects Of Structure Formation
by Hermann Janeschitz-KrieglIn addition to structure formation in crystallizing polymers and semicrystalline polymers, this second edition completes the topic of transport phenomena. It also reviews solidification by crystallization during cooling and under flow or pressure, which all play an enormous role in polymer melt processing.Generally, there is an intensive interaction between three transport phenomena: heat transfer, momentum transfer (flow, rheology) and (flow induced) crystallization. The strong interaction between the three transport phenomena is a major challenge when it comes to experimentation, and advances in this area are detailed in the book, guiding further development of sound modeling. This book enables readers to follow an advanced course in polymer processing. It is a valuable resource for polymer chemists, applied physicists, rheologists, plastics engineers, mold makers and material scientists.
Crystallization Modalities in Polymer Melt Processing: Fundamental Aspects of Structure Formation

Crystallization and Growth of Colloidal Nanocrystals (SpringerBriefs in Materials)
by Edson Roberto Leite Caue RibeiroSince the size, shape, and microstructure of nanocrystalline materials strongly impact physical and chemical properties, the development of new synthetic routes to nanocrystals with controlled composition and morphology is a key objective of the nanomaterials community. This objective is dependent on control of the nucleation and growth mechanisms that occur during the synthetic process, which in turn requires a fundamental understanding of both classical nucleation and growth and non-classical growth processes in nanostructured materials. Recently, a novel growth process called Oriented Attachment (OA) was identified which appears to be a fundamental mechanism during the development of nanoscale materials. OA is a special case of aggregation that provides an important route by which nanocrystals grow, defects are formed, and unique--often symmetry-defying--crystal morphologies can be produced. This growth mechanism involves reversible self-assembly of primary nanocrystals followed by reorientation of the assembled nanoparticles to achieve structural accord at the particle-particle interface, the removal of adsorbates and solvent molecules, and, finally, the irreversible formation of chemical bonds to produce new single crystals, twins, and intergrowths. Crystallization and Growth of Colloidal Nanocrystals provides a current understanding of the mechanisms related to nucleation and growth for use in controlling nanocrystal morphology and physical-chemical properties, and is essential reading for any chemist or materials scientist with an interest in using nanocrystals as building blocks for larger structures. This book provides a compendium for the expert reader as well as an excellent introduction for advanced undergraduate and graduate students seeking a gateway into this dynamic area of research.
Crystallization as Studied by Broadband Dielectric Spectroscopy (Advances in Dielectrics)
by Tiberio A. Ezquerra Aurora NogalesThis book presents new approaches that offer a better characterization of the interrelationship between crystalline and amorphous phases. In recent years, the use of dielectric spectroscopy has significantly improved our understanding of crystallization. The combination of modern scattering methods, using either synchrotron light or neutrons and infrared spectroscopy with dielectrics, is now helping to reveal modifications of both crystalline and amorphous phases. In turn, this yields insights into the underlying physics of the crystallization process in various materials, e.g. polymers, liquid crystals and diverse liquids. The book offers an excellent introduction to a valuable application of dielectric spectroscopy, and a helpful guide for every scientist who wants to study crystallization processes by means of dielectric spectroscopy.

Crystallization of Nanoscaled Colloids (Springer Theses)
by Philip G. BornThis thesis deals with the processes that create ordered assemblies from disordered nanoparticles. Ordered packings of nanoscale particles can exhibit unusual properties. This work investigates the self-assembly of such particles, a process widely employed for the generation of ordered structures, but not yet well understood. In situ methods are used to observe the assembly of sub-micron polymer lattices and sub-10 nm gold particles into crystalline monolayers and aggregates. On the basis of these results, the book develops new models that describe the competition between different influences, such as thermal agitation and directional forces. It suggests necessary criteria that lead to the emergence of order.

Crystals and Crystallinity in Polymers
by Finizia Auriemma Claudio De RosaProvides the tools needed to master and apply the fundamentals of polymer crystallographyUsing core concepts in physics, chemistry, polymer science and engineering, this book sheds new light on the complex field of polymer crystallography, enabling readers to evaluate polymer crystallization data and determine the best methods to use for their investigations. The authors set forth a variety of tested and proven methods for analyzing ordered and disordered structures in polymer crystals, including X-ray diffraction, electron diffraction, and microscopy. In addition to the basics, the book explores several advanced and emerging topics in the field such as symmetry breaking, frustration, and the principle of density-driven phase formation.Crystals and Crystallinity in Polymers introduces two new concepts in crystallinity and crystals in synthetic polymers. First, crystallinity in polymeric materials is compatible with the absence of true three-dimensional long-range order. Second, the disorder may be described as a structural feature, using the methods of X-ray scattering and electron diffraction analysis.The book begins by introducing the basic principles and methods for building structural models for the conformation of polymer crystal chains. Next, it covers:Packing of macromolecules in polymer crystalsMethods for extracting structural parameters from diffraction dataDefects and disorder in polymer crystalsAnalytical methods for diffuse scattering from disordered polymer structuresCrystal habitInfluence of crystal defects and structural disorder on the physical and mechanical properties of polymeric materialsCrystals and Crystallinity in Polymers examines all the possible types of structural disorder generally present in polymer crystals and describes the influence of each kind of disorder on X-ray and electron diffraction patterns. Its comprehensive, expert coverage makes it possible for readers to learn and apply the fundamentals of polymer crystallography to solve a broad range of problems.

Cscl 2: Carrying Forward the Conversation
by Timothy Koschmann Naomi Miyake Rogers HallCSCL 2: Carrying Forward the Conversation is a thorough and up-to-date survey of recent developments in Computer Supported Collaborative Learning, one of the fastest growing areas of research in the learning sciences. A follow-up to CSCL: Theory and Practice of an Emerging Paradigm (1996), this volume both documents how the field has grown and fosters a meaningful discussion of how the research program might be advanced in substantive ways. Recognizing the long-standing traditions of CSCL work in Europe and Japan, the editors sought to broaden and expand the conversation both geographically and topically. The 45 participating authors represent a range of disciplinary backgrounds, including anthropology, communication studies, computer science, education, psychology, and philosophy, and offer international perspectives on the field. For each chapter, the goal was not only to show how it connects to past and future work in CSCL, but also how it contributes to the interests of other research communities. Toward this end, the volume features a "conversational structure" consisting of target chapters, invited commentaries, and author responses. The commentaries on each chapter were solicited from a diverse collection of writers, including prominent scholars in anthropology of education, social studies of science, CSCW, argumentation, activity theory, language and social interaction, ecological psychology, and other areas. The volume is divided into three sections: *Part I explores four case studies of technology transfer involving CSILE, one of the most prominent CSCL projects. *Part II focuses on empirical studies of learning in collaborative settings. *Part III describes novel CSCL technologies and the theories underlying their design. Historically, there has been a certain amount of controversy as to what the second "C" in CSCL should represent. The conventional meaning is "collaborative" but there are many C-words that can be seen as relevant. With the publication of this volume, "conversational" might be added to the list and, in this spirit, the book might be viewed as an invitation to join a conversation in progress and to carry it forward.
Cscl: Theory and Practice of An Emerging Paradigm
by Timothy KoschmannThis book, about a newly emerging area of research in instructional technology, has as its title the acronym "CSCL." Initially, CSCL was chosen as an acronym for Computer-Supported Collaborative Learning. However, some would argue that "collaborative" is often not a descriptive term for what learners do in instructional settings; further, as the field develops, the technology used to support collaboration may not always involve computers, at least not in the direct ways they have been used to support instruction in the past. To avoid getting bogged down in this terminological debate, this book uses CSCL as a designation in its own right, leaving open to interpretation precisely what words it stands for. The authors talk a great deal about the theory underlying their work. In part, this is because that is what they were asked to do, but it is also an indication of the state of the field. In an established paradigm in which the theories and methods are well agreed upon, such discussion is less central. CSCL, however, has not yet reached the stage of "normal" science. There is much to be worked out yet. This book is offered with the hope that it will help to define a direction for future work in this field. The chapters appear in alphabetical order (except for the introductory chapter and the afterword) -- not for lack of a better way to organize the chapters, but rather because the organizational possibilities are too numerous and this order does not privilege one over another. By not imposing a topical organizing structure on this collection, it is hoped that readers will feel freer to explore the chapters in a way that best suits their needs.

Ctrl + Z: The Right to Be Forgotten
by Meg Leta JonesA gripping insight into the digital debate over data ownership, permanence and policy“This is going on your permanent record!” is a threat that has never held more weight than it does in the Internet Age, when information lasts indefinitely. The ability to make good on that threat is as democratized as posting a Tweet or making blog. Data about us is created, shared, collected, analyzed, and processed at an overwhelming scale. The damage caused can be severe, affecting relationships, employment, academic success, and any number of other opportunities—and it can also be long lasting. One possible solution to this threat? A digital right to be forgotten, which would in turn create a legal duty to delete, hide, or anonymize information at the request of another user. The highly controversial right has been criticized as a repugnant affront to principles of expression and access, as unworkable as a technical measure, and as effective as trying to put the cat back in the bag. Ctrl+Z breaks down the debate and provides guidance for a way forward. It argues that the existing perspectives are too limited, offering easy forgetting or none at all. By looking at new theories of privacy and organizing the many potential applications of the right, law and technology scholar Meg Leta Jones offers a set of nuanced choices. To help us choose, she provides a digital information life cycle, reflects on particular legal cultures, and analyzes international interoperability. In the end, the right to be forgotten can be innovative, liberating, and globally viable.
Cuba After Castro: Legacies, Challenges, and Impediments
by Bruce Hoffman Kevin F. Mccarthy Gabriella Gonzalez Louay Constant Edward Gonzalez Jeffery C. TannerWhen the end of the Castro era arrives, the successor government and the Cuban people will need to answer certain questions: How is Castro's more than four-decade rule likely to affect a post-Castro Cuba? What will be the political, social, and economic challenges Cuba will confront? What are the impediments to Cuba's economic development and democratic transition? The authors examine Castro's political legacies, Cuba's generational and racial divisions, its demographic predicament, the legacy of a centralized economy, and the need for industrial restructuring.
