The Kuroshio Power Plant
by Falin ChenBy outlining a new design or the Kuroshio power plant, new approaches to turbine design, anchorage system planning, deep sea marine engineering and power plant operations and maintenance are explored and suggested. The impact on the local environment, particularly in the face of natural disasters, is also considered to provide a well rounded introduction to plan and build a 30MW pilot power plant. Following a literature review, the six chapters of this book propose a conceptual design by focusing on the plant's core technologies and establish the separate analysis logics for turbine design and the relay platforms. This is tempered against the ecological impact of both the construction and operation of the plant. These proposed technologies and plans can be further applied to power generation in other waters such as the Gulf Stream, the East Australian Current the Humboldt Current and the East Africa Coastal Current. Engineers, students and industry professionals are provided with a solid introduction to power plant technology as well as a design with specific real world applications

Kuwait Soil Taxonomy
by Shabbir A. Shahid Samira A. OmarThis book provides guidelines to key soil taxa in the deserts of Kuwait and guidance to associated procedures for laboratory analyses of soils, leading to land use planning on informed decisions. Soils are essential to provide food, feed, and fiber in addition to multiple ecosystem services that sustain life on earth. To achieve the above services sustainably, it is essential to use soils rationally based on their potential for specific uses. This requires establishing national soil classification systems to assess soils locally and to provide guidance to other countries where similar soils may be occurring. Once soil classification is established, it becomes easier to adopt technologies established on similar soils and environmental conditions without conducting long-term and expensive experimental trial. The taxa are established based on soil’s morphological, physical, chemical, and mineralogical properties and climatic factors. It offers opportunities to maintain future soil surveys and their correlation to the soils of Kuwait. The book is useful in other arid region countries where similar soil and environmental conditions are existing, such as Bahrain, Oman, Qatar, and Saudi Arabia. The book also has international relevance, as it was prepared by extracting definitions from USDA-NRCS keys to soil taxonomy, and sections related to soils of Kuwait are added in the book. The book is a unique and excellent addition to the international soil literature.
KW/UKW Draht-Multibeam: Projektierung, Optimierung und Anpassung am Einsatzort
by George MoroianuDie Absicht, den speziell für Ballungszentren konzipierten Draht-Multibeam den Lesern zu präsentieren, hat den Autoren motiviert, dieses Buch zu schreiben. Und die Erkenntnis, dass effiziente Richtantennen heute nur mit einer Antennensoftware entworfen werden können, hat ihn überzeugt, den Inhalt basierend auf die Software EZNEC aufzubauen. Im Multibeamstapel befinden sich 3El.Oktobeams, die mit der Referenzantenne 3El-Yagi-Uda gleichwertig sind. Die Eigenschaften des 3El.Oktobeams werden analysiert, der Aufbau beschrieben und die Optimierung erklärt. Ein originelles Verfahren zur Ermittlung von Umgebungseinflüssen am Einsatzort ermöglicht, dass ein 3El.Oktobeam so projektiert werden kann, dass gleich nach der Aufstellung am Einsatzort ohne jede Anpassung, alle relevanten Performanzen erreicht werden. Auch der Zusammenbau und die Gestaltung des Trägergestells werden detailliert beschrieben. Die im Stapel integrierten 3El.Oktobeams werden getrennt gespeist. Aber es wird auch eine kettenartige Serien-Stapelspeisung beschrieben. Beide Lösungen werden verglichen und das Ergebnis kommentiert. Der Draht-Multibeam hat einen reduzierten Drehradius, wiegt ca.19 kg und kann auf leichten teleskopischen Masten auch in Ballungszentren, wo die Mehrzahl der User wohnt, ohne seitliche Bodenanker aufgebaut werden.

L2-Gain and Passivity Techniques in Nonlinear Control
by Arjan SchaftThis standard text gives a unified treatment of passivity and L2-gain theory for nonlinear state space systems, preceded by a compact treatment of classical passivity and small-gain theorems for nonlinear input-output maps. The synthesis between passivity and L2-gain theory is provided by the theory of dissipative systems. Specifically, the small-gain and passivity theorems and their implications for nonlinear stability and stabilization are discussed from this standpoint. The connection between L2-gain and passivity via scattering is detailed. Feedback equivalence to a passive system and resulting stabilization strategies are discussed. The passivity concepts are enriched by a generalised Hamiltonian formalism, emphasising the close relations with physical modeling and control by interconnection, and leading to novel control methodologies going beyond passivity. The potential of L2-gain techniques in nonlinear control, including a theory of all-pass factorizations of nonlinear systems, and of parametrization of stabilizing controllers, is demonstrated. The nonlinear H-infinity optimal control problem is also treated and the book concludes with a geometric analysis of the solution sets of Hamilton-Jacobi inequalities and their relation with Riccati inequalities for the linearization. #65533; L2-Gain and Passivity Techniques in Nonlinear Control (third edition) is thoroughly updated, revised, reorganized and expanded. Among the changes, readers will find: #65533; updated and extended coverage of dissipative systems theory #65533; substantial new material regarding converse passivity theorems and incremental/shifted passivity #65533; coverage of recent developments on networks of passive systems with examples #65533; a completely overhauled and succinct introduction to modeling and control of port-Hamiltonian systems, followed by an exposition of port-Hamiltonian formulation of physical network dynamics #65533; updated treatment of all-pass factorization of nonlinear systems The book provides graduate students and researchers in systems and control with a compact presentation of a fundamental and rapidly developing area of nonlinear control theory, illustrated by a broad range of relevant examples stemming from different application areas.

Lab Girl: A Story Of Trees, Science And Love
by Hope JahrenLab Girl is a book about work and about love, and the mountains that can be moved when those two things come together. It is told through Jahren's remarkable stories: about the discoveries she has made in her lab, as well as her struggle to get there; about her childhood playing in her father's laboratory; about how lab work became a sanctuary for both her heart and her hands; about Bill, the brilliant, wounded man who became her loyal colleague and best friend; about their field trips - sometimes authorised, sometimes very much not - that took them from the Midwest across the USA, to Norway and to Ireland, from the pale skies of North Pole to tropical Hawaii; and about her constant striving to do and be her best, and her unswerving dedication to her life's work.Visceral, intimate, gloriously candid and sometimes extremely funny, Jahren's descriptions of her work, her intense relationship with the plants, seeds and soil she studies, and her insights on nature enliven every page of this thrilling book. In Lab Girl, we see anew the complicated power of the natural world, and the power that can come from facing with bravery and conviction the challenge of discovering who you are.

A Lab of One's Own: One Woman's Personal Journey Through Sexism in Science
by Rita Colwell Sharon Bertsch McGrayneA riveting memoir-manifesto from the first female director of the National Science Foundation about the entrenched sexism in science, the elaborate detours women have taken to bypass the problem, and how to fix the system. If you think sexism thrives only on Wall Street or in Hollywood, you haven&’t visited a lab, a science department, a research foundation, or a biotech firm. Rita Colwell is one of the top scientists in America: the groundbreaking microbiologist who discovered how cholera survives between epidemics and the former head of the National Science Foundation. But when she first applied for a graduate fellowship in bacteriology, she was told, &“We don&’t waste fellowships on women.&” A lack of support from some male superiors would lead her to change her area of study six times before completing her PhD. A Lab of One&’s Own documents all Colwell has seen and heard over her six decades in science, from sexual harassment in the lab to obscure systems blocking women from leading professional organizations or publishing their work. Along the way, she encounters other women pushing back against the status quo, including a group at MIT who revolt when they discover their labs are a fraction of the size of their male colleagues&’. Resistance gave female scientists special gifts: forced to change specialties so many times, they came to see things in a more interdisciplinary way, which turned out to be key to making new discoveries in the twentieth and twenty-first centuries. Colwell would also witness the advances that could be made when men and women worked together—often under her direction, such as when she headed a team that helped to uncover the source of the anthrax used in the 2001 letter attacks. A Lab of One&’s Own shares the sheer joy a scientist feels when moving toward a breakthrough, and the thrill of uncovering a whole new generation of female pioneers. But it is also the science book for the #MeToo era, offering an astute diagnosis of how to fix the problem of sexism in science—and a celebration of the women pushing back.

Label-Free Biosensor Methods in Drug Discovery
by Ye FangThis volume explores label-free biosensors, advantageous in part because this technology bypasses the need of labels, reporters, and cell engineering, all of which are common to labeled techniques but may introduce artifacts in assay results. Addressing several fundamental and practical aspects as to how to implement label-free methods in the drug discovery process, this book covers a wide range of topics, including binding kinetics determination, fragment screening, antibody epitope mapping, protein-protein interaction profiling and screening, receptor pathway deconvolution, drug pharmacology profiling and screening, target identification, drug toxicity assessment, and physical phenotype profiling and diagnostics based on various cellular processes such as cell adhesion, migration, invasion, infection, and inflammation. As part of the Methods in Pharmacology and Toxicology series, chapters aim to provide key detail and implementation advice to aid with progress in the lab. Practical and thorough, Label-Free Biosensor Methods in Drug Discovery provides a new avenue for rapid access to a focused collection of highly regarded contributions in the field.
Label-Free Super-Resolution Microscopy (Biological and Medical Physics, Biomedical Engineering)
by Vasily AstratovThis book presents the advances in super-resolution microscopy in physics and biomedical optics for nanoscale imaging. In the last decade, super-resolved fluorescence imaging has opened new horizons in improving the resolution of optical microscopes far beyond the classical diffraction limit, leading to the Nobel Prize in Chemistry in 2014. This book represents the first comprehensive review of a different type of super-resolved microscopy, which does not rely on using fluorescent markers. Such label-free super-resolution microscopy enables potentially even broader applications in life sciences and nanoscale imaging, but is much more challenging and it is based on different physical concepts and approaches. A unique feature of this book is that it combines insights into mechanisms of label-free super-resolution with a vast range of applications from fast imaging of living cells to inorganic nanostructures. This book can be used by researchers in biological and medical physics. Due to its logically organizational structure, it can be also used as a teaching tool in graduate and upper-division undergraduate-level courses devoted to super-resolved microscopy, nanoscale imaging, microscopy instrumentation, and biomedical imaging.
Labnet: Toward A Community of Practice (Technology and Education Series)
by Richard Ruopp Shahaf Gal Brian Drayton Meghan PfisterConnected by a computer telecommunications network, ninth-graders from eight high schools scattered thousands of miles across Alaska work together, building a robot submarine to gather samples from the floor of Prince William Sound. This is high school science as some teachers and educational reformers today envision it -- centered on student projects that encourage learning by doing...supported by modern technology...enriched by collaboration among students and teachers, both face to face and far apart. This example is drawn from LabNet, a three-year effort funded by the National Science Foundation. The project was conducted by Technical Education Research Centers (TERC), a nonprofit educational organization dedicated to improving mathematics and science education. Eventually reaching 562 teachers in 37 states, Puerto Rico, and American Samoa, LabNet had a direct impact on their classroom practice. In a follow-up evaluation, the majority said they had assigned their students more projects and had used LabNet's telecommunications network to exchange project ideas with other teachers. This book is the story of LabNet as told by its editors, with 14 additional essays on science projects -- both theoretical and practical -- by LabNet teachers and TERC staff.

Labor and the Locavore
by Margaret GrayIn the blizzard of attention around the virtues of local food production, food writers and activists place environmental protection, animal welfare, and saving small farms at the forefront of their attention. Yet amid this turn to wholesome and responsible food choices, the lives and working conditions of farmworkers are often an afterthought.Labor and the Locavore focuses on one of the most vibrant local food economies in the country, the Hudson Valley that supplies New York restaurants and farmers markets. Based on more than a decade's in-depth interviews with workers, farmers, and others, Gray's examination clearly shows how the currency of agrarian values serves to mask the labor concerns of an already hidden workforce. She also explores the historical roots of farmworkers' predicaments and examines the ethnic shift from Black to Latino workers. With an analysis that can be applied to local food concerns around the country, this book challenges the reader to consider how the mentality of the alternative food movements implies a comprehensive food ethic that addresses workers' concerns.
Labor in the Era of Globalization
by Clair Brown Barry Eichengreen Michael ReichThe third quarter of the twentieth century was a golden age for labor in the advanced industrial countries, characterized by rising incomes, relatively egalitarian wage structures, and reasonable levels of job security. The subsequent quarter-century has seen less positive performance along a number of these dimensions. This period has instead been marked by rapid globalization of economic activity that has brought increased insecurity to workers. The contributors to this volume, prominent scholars from the United States, Europe, and Japan, distinguish four explanations for this historic shift. These include 1) rapid development of new technologies; 2) global competition for both business and labor; 3) deregulation of industry with more reliance on markets; and 4) increased immigration of workers, especially unskilled workers, from developing countries. In addition to analyzing the causes of these trends, the contributors also investigate important consequences, ranging from changes in collective bargaining and employment relations to family formation decisions and incarceration policy.
