Continuum Mechanics through the Ages - From the Renaissance to the Twentieth Century: From Hydraulics to Plasticity (Solid Mechanics and Its Applications #223)

by Gérard A. Maugin

Mixing scientific, historic and socio-economic vision, thisunique book complements two previously published volumes on the history ofcontinuum mechanics from this distinguished author. In this volume, Gérard A. Maugin looks at the period from the renaissance to the twentieth century and heincludes an appraisal of the ever enduring competition between molecular andcontinuum modelling views. Chapters trace early works in hydraulics and fluid mechanics not covered in theother volumes and the author investigates experimental approaches, essentiallybefore the introduction of a true concept of stress tensor. The treatment ofsuch topics as the viscoelasticity of solids and plasticity, fracture theory,and the role of geometry as a cornerstone of the field, are all explored. Readers will find a kind of socio-historical appraisal of the seminalcontributions by our direct masters in the second half of the twentiethcentury. The analysis of the teaching and research texts by Duhem, Poincaré andHilbert on continuum mechanics is key: these provide the most valuabledocumentary basis on which a revival of continuum mechanics and itsformalization were offered in the late twentieth century. Altogether, the three volumes offer a generous conspectus of the developmentsof continuum mechanics between the sixteenth century and the dawn of thetwenty-first century. Mechanical engineers, applied mathematicians andphysicists alike will all be interested in this work which appeals to allcurious scientists for whom continuum mechanics as a vividly evolving sciencestill has its own mysteries.

Continuum Mechanics Through the Twentieth Century: A Concise Historical Perspective (Solid Mechanics and Its Applications #196)

Continuum Mechanics with Eulerian Formulations of Constitutive Equations (Solid Mechanics and Its Applications #265)

by M.B. Rubin

This book focuses on the need for an Eulerian formulation of constitutive equations. After introducing tensor analysis using both index and direct notation, nonlinear kinematics of continua is presented. The balance laws of the purely mechanical theory are discussed along with restrictions on constitutive equations due to superposed rigid body motion. The balance laws of the thermomechanical theory are discussed and specific constitutive equations are presented for: hyperelastic materials; elastic–inelastic materials; thermoelastic–inelastic materials with application to shock waves; thermoelastic–inelastic porous materials; and thermoelastic–inelastic growing biological tissues.

Continuum Modeling: An Approach Through Practical Examples (SpringerBriefs in Applied Sciences and Technology)

by Adrian Muntean

This book develops continuum modeling skills and approaches the topic from three sides: (1) derivation of global integral laws together with the associated local differential equations, (2) design of constitutive laws and (3) modeling boundary processes. The focus of this presentation lies on many practical examples covering aspects such as coupled flow, diffusion and reaction in porous media or microwave heating of a pizza, as well as traffic issues in bacterial colonies and energy harvesting from geothermal wells. The target audience comprises primarily graduate students in pure and applied mathematics as well as working practitioners in engineering who are faced by nonstandard rheological topics like those typically arising in the food industry.

Continuum Physics (Graduate Texts in Physics)

by Peter Hertel

This small book on the properties of continuously distributed matter covers a huge field. It sets out the governing principles of continuum physics and illustrates them by carefully chosen examples. These examples comprise structural mechanics and elasticity, fluid media, electricity and optics, thermoelectricity, fluctuation phenomena and more, from Archimedes' principle via Brownian motion to white dwarfs. Metamaterials, pattern formation by reaction-diffusion and surface plasmon polaritons are dealt with as well as classical topics such as Stokes' formula, beam bending and buckling, crystal optics and electro- and magnetooptic effects, dielectric waveguides, Ohm's law, surface acoustic waves, to mention just some. The set of balance equations for content, flow and production of particles, mass, charge, momentum, energy and entropy is augmented by material, or constitutive equations. They describe entire classes of materials, such as viscid fluids and gases, elastic media, dielectrics or electrical conductors. We discuss the response of matter to rapidly oscillating external parameters, in particular the electric field strength of light, in the framework of statistical thermodynamics.< An appendix on fields and a glossary round off this bird's-eye view on continuum physics. Students of physics, engineering and related fields will benefit from the clear presentation of worked examples and the variety of solution methods, including numerical techniques. Lecturers or advanced students may profit from the unified view on a substantial part of physics. It may help them to embed their research field conceptually within a wider context.

Continuum Thermodynamics and Constitutive Theory

by Christina Papenfuß

This book presents different thermodynamic approaches in the area of constitutive theory: thermodynamics of irreversible processes, rational thermodynamics, and extended thermodynamics. These different approaches are analyzed with respect to their presuppositions, as well as to their results, and each method is applied to several important examples. In many cases these examples are archetypes for numerous technologically important materials; i.e. complex materials having an internal structure. Some of the examples dealt with in this book are liquid crystals, colloid suspensions, ans fiber suspensions. The book well serves students and researchers who have basic knowledge in continuum mechanics and thermodynamics. It provides a systematic overview of the vast field of thermodynamic constitutive theory, beginning from a historical perspective and concluding with outstanding questions in recent research.

Contours of Canadian Thought

by A. B. Mckillop

The leaps of knowledge in nineteenth-century science shook the foundations of religious and humanistic values throughout much of the world. The Darwinian Revolution and similar developments presented enormous philosophical challenges to Canadian scientists, philosophers, and men of letters. Their responses, many and varied, form a central theme in this collection of essays by one of Canada's leading intellectual historians.McKillop explores the thought of a number of English-Canadian thinkers from the 1860s to the 1920s, decades that saw Canada's entry into the modern age. We meet Daniel Wilson, an educator and ethnologist for whom the pursuit of science was a form of poetic engagement, requiring the poet's sensibilities; John Watson, one of the world's leading exponents of objective idealism, whose philosophical premises helped to undermine the very religious tradition he sought to bolster; and William Dawson LeSueur, an apostle of Positivism, whose spirited defence of critical inquiry and evolutionary social ethics led him towards an entirely contradictory position.In addition to profiles of individuals, McKillop considers the ways in which their ideas operated in the context of Canadian institutions including the universities and the press. From these prospectives emerges a detailed analysis of the life of the mind of English Canada in an age of questioning, of doubt, and of struggle to reorient the intellectual and philosophical positions of a quickly changing society.

Contours of Feminist Political Ecology (Gender, Development and Social Change)

by Wendy Harcourt Ana Agostino Rebecca Elmhirst Marlene Gómez Panagiota Kotsila

This open access book sets out the contours of feminist political ecology (FPE) as a major contribution to ongoing debates in the field. As Professor Lyla Mehta says in her Foreword, the book is "foregrounding multiple ways of knowing and being, thus enabling new conceptions of politics, justice and alternatives to dominant, capitalist development trajectories". In an innovative methodological twist, the edited book engages the reader in conversations that have emerged from the multi-sited and cross-generational dialogues of the Well-Being Ecology Gender cOmmunities (WEGO) network over the last four years. The conversations explore topics that range from climate change and extractivism, to body politics and health, degrowth, care and community well-being. The authors reflect on their collective learning process as they map out the new directions of FPE research and analysis. The chapters highlight WEGO transnational/transdisciplinary conversations with local communities, social movements and different academic spaces. The book foregrounds the ethics of doing feminist work inside and outside academe and brings to life the importance of doing reflexive research aware of situated historical and contemporary geographical contours of power.

Contra el rebaño digital: Un manifiesto

by Jaron Lanier

El fascinante manifiesto por un uso creativo de la tecnología de uno de los creadores de Internet. Contra el rebaño digital es uno de los libros que más han dado que hablar en los últimos tiempos: un aviso contra nuestra obsesión por la tecnología y, en concreto, por internet, escrito por uno de los expertos más estimulantes y visionarios. La temprana dedicación de Lanier a la realidad virtual y el desarrollo de tecnologías en red son legendarias, así como sus artículos, que atacan muchas de las cuestiones que el mundo de la tecnología considera sagradas. En este manifiesto, Lanier apunta contra lo que ha bautizado como la cultura nerd de internet o el «maoísmo digital», es decir, la tendencia de la comunidad tecnológica de primar la plataforma sobre el contenido y los ordenadores sobre las personas. En total contraste con los que saludan el triunfo del contenido generado por los usuarios, Lanier ve una internet desinformada y tediosa, en la que la cantidad se impone a la calidad y las buenas ideas son acalladas a base de gritos. Pero Contra el rebaño digital no es una diatriba antitecnológica. Es un manifiesto fresco y energizante dedicado a quienes la tecnología les inspira aunque les decepcione el modo en que es empleada. Lanier propone a los usuarios de la red frenar un poco, generar contenidos profundos en vez de llamativos y sacar el máximo partido de internet en vez de usarla ciegamente para todo. Reseñas: «Aunque Lanier no pertenece a mi generación, nos conoce y nos comprende bien, y ha escrito un libro breve y aterrador, Contra el rebaño digital, que se hace eco de mi propia incomodidad, pero partiendo de un conocimiento y una perspicacia reales, tanto en lo práctico como en lo filosófico.» Zadie Smith, The New York Review of Books «Lúcido, poderoso y persuasivo. Una lectura imprescindible para todos aquellos que observan cómo la red y la tecnología que usamos a diario están modelando la cultura y el mercado.» Michiko Kakutani, The New York Times «Este es el libro más importante escrito hasta la fecha sobre nuestro mundo cada vez más digitalizado. Será recordado como el manifiesto que salvó a la humanidad al límite de la extinción, o como el último mensaje inteligente de una especie obsoleta.» Douglas Rushkoff «Apasionante y estimulante. Un correctivo necesario en los salones de debates tecnológicos.» San Francisco Chronicle «Importante... Lo que subyace en el ciberpensamiento de Lanier es una fe fundamentalmente humanista en la tecnología.» Los Angeles Times «Para quienes quieren leer para pensar, y leer para transformar, Contra el rebaño digital es el libro con el que empezar la década. Crudo, alborotador e inesperado. Y también muy entretenido.» Times Higher Education Supplement «El libro fundamental para comprender el mundo después de Google.» The Stranger (Seattle) «Poético y profético, este puede ser el libro más importante del año. ¡Lee este libro y álzate contra la rigidez de la red!» The Times (Londres) «Inspirado, enojoso y totalmente necesario. Bienvenidos al primer gran llamamiento del siglo en defensa de un "nuevo humanismo digital" frente a la conformidad en red del ciberespacio.» The Independent «Un nuevo y convincente manifiesto... Lanier es el primer gran apóstata de la era de internet.» Newsweek

Contra la perfección: La ética en la era de la ingeniería genética

by Michael J. Sandel

¿Qué tiene de malo manipular nuestra naturaleza o la de otros seres? El filósofo Michael Sandel trata de responder a esta pregunta a través de un ameno pero profundo repaso del campo de la bioética. Desde hace tiempo es evidente que la ciencia va más deprisa de lo que nuestras intuiciones morales son capaces de asumir: hoy ya es materialmente posible encargar una mascota exactamente igual que la que acabamos de enterrar; o reivindicar que se asegure que nuestros hijos tendrán las mismas determinaciones genéticas que nosotros, incluso cuando consisten en algo como la sordera. La mayoría de las personas se sienten cuando menos incómodas ante algunas de las posibilidades que abre la ingeniería genética, aunque no siempre les resulta fácil explicar por qué. ¿Qué tiene de malo manipular nuestra naturaleza? ¿Dónde están las líneas rojas, si las hay?Contra la perfección explora estos y otros dilemas morales relacionados con la búsqueda de nuestro propio perfeccionamiento. Sandel argumenta que la búsqueda de la perfección es imperfecta por razones que van más allá de la seguridad y de la equidad, y nos lleva más allá de los familiares términos del discurso político para mostrarnos que la revolución genética transformará el modo en que se discute sobre cuestiones éticas y obligará a reintroducir las cuestiones de orden espiritual en el centro del debate político. Para debatir sobre la ética del perfeccionamiento es preciso abordar preguntas que el mundo moderno ha ignorado desde hace décadas, en gran medida porque bordean el terreno tradicional de la teología. Pero nuestros nuevos poderes en el ámbito de la biotecnología hacen inevitables estas preguntas. Abordarlas es la tarea de este libro, escrito por uno de los filósofos políticos más notables de nuestro tiempo.

Contraception: A Concise History (The MIT Press Essential Knowledge series)

by Donna J. Drucker

The development, manufacturing, and use of contraceptive methods from the late nineteenth century to the present, viewed from the perspective of reproductive justice.The beginning of the modern contraceptive era began in 1882, when Dr. Aletta Jacobs opened the first birth control clinic in Amsterdam. The founding of this facility, and the clinical provision of contraception that it enabled, marked the moment when physicians started to take the prevention of pregnancy seriously as a medical concern. In this volume in the MIT Press Essential Knowledge series, Donna Drucker traces the history of modern contraception, outlining the development, manufacturing, and use of contraceptive methods from the opening of Dr. Jacobs's clinic to the present. Drucker approaches the subject from the perspective of reproductive justice: the right to have a child, the right not to have a child, and the right to parent children safely and healthily.Drucker describes contraceptive methods available before the pill, including the diaphragm (dispensed at the Jacobs clinic) and condom, spermicidal jellies, and periodic abstinences. She looks at the development and dissemination of the pill and its chemical descendants; describes technological developments in such non-hormonal contraceptives as the cervical cap and timing methods (including the “rhythm method” favored by the Roman Catholic church); and explains the concept of reproductive justice. Finally, Drucker considers the future of contraception—the adaptations of existing methods, new forms of distribution, and ongoing efforts needed to support contraceptive access worldwide.

Contract Research and Development Organizations: Their Role in Global Product Development

by Shayne C. Gad Charles B. Spainhour

The last 10 years have seen a seismic shift in therapeutic product development and testing. In both the pharmaceutical (both small and large molecule) and medical device sectors, the vast majority of testing and evaluation of products is not performed within innovator companies, but rather has been outsourced to a growing universe of commercial organizations. The authors both have more than 30 years experience in this field, and both have worked within innovator companies, for CROs, and as consultants in the field. Contract Research and Development Organizations: Their Role in Global Product Development has been crafted by these authors to provide a how to guide for all aspects of working with CROs in selecting, working with and ensuring the best possible desirable outcome of having the R&D function, or substantial parts of it, outsourced. It uses as the exemplary case nonclinical safety assessment, biocompatibility and efficacy testing which are to be performed to select the best possible candidate compound, device or formulation and then moving the resulting regulated therapeutic medical product into and through the development process and to marketing approval. But also covered are the contract synthesis of drug substances and corresponding manufacture of biologics and manufacture of products, formulation development, clinical evaluation, regulatory and document preparation support, and use of consultants. Included in the volume are an exhaustive listing of those CROs in the (drug and device) safety evaluation sector and their contact information and capabilities, and extensive similar listing for the other types of contract service providers. Also included are guidances on how to monitor ongoing work at contract facilities and audit check lists for GLP, GMP and GCP facilities. These listings are international in scope, and a specific chapter addresses working with some of the newer international CROs.

Contract Theory in Continuous-Time Models (Springer Finance)

by Jianfeng Zhang Jakša Cvitanic

In recent years there has been a significant increase of interest in continuous-time Principal-Agent models, or contract theory, and their applications. Continuous-time models provide a powerful and elegant framework for solving stochastic optimization problems of finding the optimal contracts between two parties, under various assumptions on the information they have access to, and the effect they have on the underlying "profit/loss" values. This monograph surveys recent results of the theory in a systematic way, using the approach of the so-called Stochastic Maximum Principle, in models driven by Brownian Motion. Optimal contracts are characterized via a system of Forward-Backward Stochastic Differential Equations. In a number of interesting special cases these can be solved explicitly, enabling derivation of many qualitative economic conclusions.

A Contract with the Earth

by Newt Gingrich Terry L. Maple

Focusing the environmental debate on the principle of common commitment, former Speaker of the House Newt Gingrich and eminent conservationist Terry L. Maple present A Contract with the Earth. They declare a need for bipartisan environmentalism—a new era of environmental stewardship with principles that they believe most Americans will share. While acknowledging that liberals and conservatives do not see eye to eye on many issues, Gingrich and Maple argue successfully that environmental stewardship is a mainstream value that transcends partisan politics. Their thoughtful approaches to our environmental challenges are based on three main premises: environmental leadership is integral to America's role in the world, technologically savvy environmental entrepreneurs can and should be the cornerstone of environmental solutions, and cooperation and incentives must be dramatically increased to achieve workable and broadly supported environmental solutions.Gingrich and Maple believe that most people—regardless of how they categorize themselves politically—are weary of the legal and political conflicts that prevent individuals and communities from realizing the benefits of environmental conservation. The foundation of the book—a ten-point Contract with the Earth—promotes ingenuity over rhetoric as the way forward.

Contractors and War: The Transformation of US Expeditionary Operations

by Christopher Kinsey Malcolm Hugh Patterson

The U. S. military is no longer based on a Cold War self-sufficient model. Today's armed forces are a third smaller than they were during the Cold War, and yet are expected to do as much if not more than they did during those years. As a result, a transformation is occurring in the way the U. S. government expects the military to conduct operations-with much of that transformation contingent on the use of contractors to deliver support to the armed forces during military campaigns and afterwards. Contractors and Warexplains the reasons behind this transformation and evaluates how the private sector will shape and be shaped by future operations. The authors are drawn from a range of policy, legislative, military, legal, and academic backgrounds. They lay out the philosophical arguments supporting the use of contractors in combat and stabilization operations and present a spectrum of arguments that support and criticize emergent private sector roles. The book provides fresh policy guidance to those who will research, direct, and carry out future deployments.

Contractual Management: Managing Through Contracts

by Ralph Schuhmann Bert Eichhorn

The Concept Contractual Management offers a holistic approach to managerial decision-making based on contracts or business processes that are related to contracts. It explains management from the point of view of the contract, just as it interprets the contract from the point of view of management. Thus, the approach highlights the great inherent potential of contracts for managing companies, transactions and business relationships. The book addresses students as well as practitioners and gives insights into the usage of contracts to manage companies or relationships. It covers contract handling from preliminary deliberations to negotiations, implementation, and all the way to the evaluation of the contract within the company. Furthermore, it provides competencies to design and implement a contract and to organize the relevant processes. The Content In Part 1, the book explains the theoretical foundations of Contractual Management; in Part 2, the application of the approach is illustrated through case studies which cover various sectors, industries, company sizes, contract types, and management situations. Theory part: Contractual Management – A Holistic Approach to a Diverse Issue. Case study part: 11 case studies arranged according to specific contract-related topics: Information and Communication – Change – Enterprise Networks – Conflict – Accounting and Financing – Legal Compliance – Societal Steering. The Editors Professor Dr. Ralph Schuhmann: After holding a senior management position in industry, Ralph Schuhmann now teaches Business Law at Ernst-Abbe-Hochschule in Jena, Germany. He is the scientific director of the Contractual Management Institute at SRH Hochschule Berlin and has published various articles on contract law and contract management. Professor Dr. Bert Eichhorn: Before his appointment as professor for International Law and Business Law at SRH Hochschule Berlin, Bert Eichhorn worked as a legal consultant at the EU Parliament and as a lawyer. He has published numerous articles in national and international scientific journals in the area of contract management and international law. He is the managing director of the Contractual Management Institute at SRH Hochschule Berlin.

Contradictions: Neuroscience and Religion (Springer Praxis Books)

by José M. Musacchio

"Contradictions" is a general interest book that exposes the incompatibility between popular religious beliefs and the scientific view of human nature. It begins with a survey of the evolution of religions and their continuing, often irrational, influences in modern society. Then, based on his long experience in neuroscience, the author takes issue with Decartes about the duality of body and soul. He presents case studies of patients with brain diseases and from these deduces that the soul, far from being separate and supernatural, is no more or less than our way of experiencing our brains ... and which correspondingly disintegrates when they do. Convincing clinical findings and powerful arguments about the universality of truth make this book a bold contribution to the debate about belief and religion in the modern world.

The Contrarian: Peter Thiel and Silicon Valley's Pursuit of Power

by Max Chafkin

A biography of venture capitalist and entrepreneur Peter Thiel, the enigmatic, controversial, and hugely influential power broker who sits at the dynamic intersection of tech, business, and politics &“Max Chafkin&’s The Contrarian is much more than a consistently shocking biography of Peter Thiel, the most important investor in tech and a key supporter of the Donald Trump presidency. It&’s also a disturbing history of Silicon Valley that will make you reconsider the ideological foundations of America&’s relentless engine of creative destruction.&”—Brad Stone, author of The Everything Store and Amazon UnboundSince the days of the dot-com bubble in the late 1990s, no industry has made a greater impact on the world than Silicon Valley. And few individuals have done more to shape Silicon Valley than Peter Thiel. The billionaire venture capitalist and entrepreneur has been a behind-the-scenes operator influencing countless aspects of our contemporary way of life, from the technologies we use every day to the delicate power balance between Silicon Valley, Wall Street, and Washington. But despite his power and the ubiquity of his projects, no public figure is quite so mysterious.In the first major biography of Thiel, Max Chafkin traces the trajectory of the innovator's singular life and worldview, from his upbringing as the child of immigrant parents and years at Stanford as a burgeoning conservative thought leader to his founding of PayPal and Palantir, early investment in Facebook and SpaceX, and relationships with fellow tech titans Mark Zuckerberg, Elon Musk, and Eric Schmidt. The Contrarian illuminates the extent to which Thiel has sought to export his values to the corridors of power beyond Silicon Valley, including funding the lawsuit that destroyed the blog Gawker and strenuously backing far-right political candidates, notably Donald Trump for president in 2016. Eye-opening and deeply reported, The Contrarian is a revelatory biography of a one-of-a-kind leader and an incisive portrait of a tech industry whose explosive growth and power is both thrilling and fraught with controversy.

Contrast-Enhanced Ultrasound: From Simple to Complex

by Alexander N. Sencha Yury N. Patrunov

This book provides a comprehensive analysis of the value of contrast-enhanced ultrasound (CEUS) in the diagnosis of a wide variety of pathologies. Sonography reliably identifies a wide range of diseases, and the efficacy of modern ultrasound has dramatically improved with contrast enhancement. This book covers almost all aspects of CEUS starting from basic principles and ending with features of its application in individual organs. In particular, it explores the diseases of abdominal, retroperitoneal, and pelvic organs as well as superficial structures, highlighting the characteristic features of typical findings. Focal lesions are discussed in depth, with attention to their early detection and differential diagnosis. Besides, a practical approach to the stratification of the risk of malignancies is provided. The authors summarized their own experience with CEUS in oncology, hepatology, gynecology, urology, endocrinology, and other fields of medicine. The role of CEUS in differential diagnosis of various disorders of the female reproductive system is comprehensively discussed as well. The presentation is clear and concise, and richly illustrated. The book will be a helpful tool for both residents and practitioners approaching ultrasound diagnostics, as well for more experienced radiologists and other professionals.

Contrast-Enhanced Ultrasound in Pediatric Imaging

by Paul S. Sidhu Maria E. Sellars Annamaria Deganello

This book is a comprehensive guide to the rapidly evolving field of contrast-enhanced ultrasound (CEUS) in the child. The uses and interpretation of CEUS are clearly explained with the aid of numerous illustrations. The coverage encompasses both established indications, such as focal liver lesions, abdominal solid organ injury, and vesicoureteral reflux, and a range of newer applications. Extensive information is also provided on microbubble agents and their use in the pediatric age group, as well as on practical aspects of setting up a CEUS service for children.CEUS is a safe imaging method that is ideal for the young patient and can be used for problem solving in a number of clinical situations. Ultrasound combined with microbubble contrast avoids the ionizing radiation of a CT examination, the use of iodinated contrast, the need for sedation or a general anesthetic, and the complexities of MR imaging. In bringing readers up to date with best practice and the latest innovations in CEUS, this book will be of value for pediatric radiologists, pediatric sonographers/technicians, and pediatricians.

Contrast-Enhanced Ultrasound of the Urinary Tract

by Maurizio Atzori Giovanni Regine Romano Fabbri

This book examines in detail the diagnostic impact of contrast-enhanced ultrasound in the evaluation of urinary tract pathology, paying particular attention to the diagnostic gain that may be expected in relation to other imaging techniques such as CT and MRI. The role of contrast-enhanced ultrasound is evaluated in a range of pathologies, including ischemia, trauma, inflammation, cystic lesions, and solid tumors, as well as in the imaging of anatomic variants. New applications, for example monitoring of kidney transplantation, assessment of urinary bladder lesions, and diagnosis of vesico-ureteric reflux, are also covered. The presented cases, drawn from the authors' personal clinical caseload, include images obtained using multimodality techniques, sometimes with 3D CT reconstruction. The authors' own experiences are compared with the most recent reports in the scientific literature.
