Dermatotoxicology Methods: The Laboratory Worker's Ready Reference

by Howard I. Maibach Francis N. Marzulli

This work presents and evaluates methods employed to identify the potential of certain types of chemicals to adversely affect the skin. A variety of test methods are included such as tests for skin penetration, metabolism, irritation, the skin immune system, photo effects, skin cancer, and topical effects of retinoids and depigmenting chemicals. Tests for chemicals that affect the reproductive and nervous system are also included. Both animal and human tests that have been standardised and tests that are under development and employ animal alternatives are addressed in this book. Besides different testing methods, a rationale for accepting non-animal models and a review of some regulatory agency discussions about animal alternative tests are included.

It allows for the identification of dozens of morphological features that are particularly important in identifyin

Derrida after the End of Writing: Political Theology and New Materialism (Perspectives in Continental Philosophy)

by Clayton Crockett

What are we to make of Jacques Derrida’s famous claim that “every other is every other,” if the other could also be an object, a stone or an elementary particle? Derrida’s philosophy is relevant not just for human ethical language and animality, but to profound developments in the physical and natural sciences, as well as ecology. Derrida After the End of Writing argues for the importance of reading Derrida’s later work from a new materialist perspective. In conversation with Heidegger, Lacan, and Deleuze, and critically engaging newer philosophies of speculative realism and object-oriented ontology, Crockett claims that Derrida was never a linguistic idealist. Furthermore, something changes in his later philosophy something that cannot be simply described as a “turn.” In Catherine Malabou’s terms, there is a shift from a motor scheme of writing to a motor scheme of plasticity. Crockett explores some of the implications of interpreting Derrida through the new materialist lens of technicity or plasticity, attending to the significance of ethics, religion, and politics in his later work. By reading Derrida from a new materialist perspective, Crockett provides fresh readings of his ideas of sovereignty, religion, responsibility, and mourning. These new readings produce fruitful engagements with the thinkers who have followed Derrida, including Malabou, Timothy Morton, John D. Caputo, and Karen Barad. Here is a new reading of Derrida that moves beyond conventional understandings of poststructuralism and deconstruction, a reading that is responsive to and critical of some of the crucial developments shaping the humanities today.

Desalination Concentrate Management

by Bradley Ladewig Benjamin Asquith

This book examines five methods used for concentrate management, namely; disposal to surface water, disposal to sewerage, deep well injection, land applications and evaporation ponds. In particular, the book focuses on the design, siting, cost, and environmental impacts of these methods. While these methods are widely practiced in a variety of settings already, there are many limitations that restrict the use of certain disposal options in particular locations.

Desalination and Water Security (Earthscan Studies in Water Resource Management)

by Chris Anastasi

Desalination is to the water industry what renewables are to the electricity sector. However, unlike renewables, the former is being deployed in a quiet revolution away from public glare. This book provides a holistic view of desalination, highlighting the important role this technology can play in providing safe access to water across the globe. It describes the context for this technology to flourish in the coming decades. It discusses the pressures on freshwater resources and the key role the desalination industry plays as it moves from a good-to-have provider today to a must-have mainstream water solution in the future. The book explores the vital elements of the desalination industry, including the winning technologies and how further technological developments will reduce costs and increase deployment into new areas. It also addresses the energy used and the key environmental issues of carbon dioxide emissions and brine waste production. Using a series of country case studies, the book illustrates how desalination can supplement natural water resources in different environments and for different purposes, and how it is supporting domestic and economic activity. Providing a forward-thinking assessment, the book considers developments over the next 30 years as climate change impacts become even more apparent. This book will be of great interest to those working to alleviate water scarcity and improve water security. It will also be of interest to those in water resource management, water policy and regulation, water science, and environmental engineering.

Desalination: A National Perspective

by National Research Council of the National Academies

There has been an exponential increase in desalination capacity both globally and nationally since 1960, fueled in part by growing concern for local water scarcity and made possible to a great extent by a major federal investment for desalination research and development. Traditional sources of supply are increasingly expensive, unavailable, or controversial, but desalination technology offers the potential to substantially reduce water scarcity by converting the almost inexhaustible supply of seawater and the apparently vast quantities of brackish groundwater into new sources of freshwater. Desalination assesses the state of the art in relevant desalination technologies, and factors such as cost and implementation challenges. It also describes reasonable long-term goals for advancing desalination technology, posits recommendations for action and research, estimates the funding necessary to support the proposed research agenda, and identifies appropriate roles for governmental and nongovernmental entities.

Desalination: Water from Water

by Jane Kucera

“Blue is the new green.” This is an all-new revised edition of a modern classic on one of the most important subjects in engineering: Water. Featuring a total revision of the initial volume, this is the most comprehensive and up-to-date coverage of the process of desalination in industrial and municipal applications, a technology that is becoming increasingly more important as more and more companies choose to “go green.” This book covers all of the processes and equipment necessary to design, operate, and troubleshoot desalination systems, from the fundamental principles of desalination technology and membranes to the much more advanced engineering principles necessary for designing a desalination system. Earlier chapters cover the basic principles, the economics of desalination, basic terms and definitions, and essential equipment. The book then goes into the thermal processes involved in desalination, such as various methods of evaporation, distillation, recompression, and multistage flash. Following that is an exhaustive discussion of the membrane processes involved in desalination, such as reverse osmosis, forward osmosis, and electrodialysis. Finally, the book concludes with a chapter on the future of these technologies and their place in industry and how they can be of use to society. This book is a must-have for anyone working in water, for engineers, technicians, scientists working in research and development, and operators. It is also useful as a textbook for graduate classes studying industrial water applications.

Descartes on Mathematics, Method and Motion: On the Role of Cartesian Physics in the Scientific Revolution (SpringerBriefs in Philosophy)

by Ladislav Kvasz

This book argues that Descartes’ physics was a milestone on the road to modern mathematical physics. After Newton introduced a completely different approach to mathematical description of motion, Descartes’ physics became obsolete and even difficult to comprehend. This text follows the language of Descartes and the means of which motion can be described. It argues that Descartes achieved almost everything that later Newton was able to do—to describe the motion of interacting bodies- by different (i.e. algebraic) means. This volume completely refutes the received view according to which Descartes’ physics was merely a kind of discursive natural philosophy. To make this interpretation more plausible the book follows Descartes’ ideas from his early work in mathematics, through his invention of the analytic method towards his mature physics. It shows that Descartes followed a similar heuristic pattern.The volume appeals to students and researchers; it invites the reader equippedwith minimal understanding of college mathematics to follow Descartes on his intellectual journey through the Scientific Revolution. The reader will gain a deeper understanding of the role of mathematical language in the creation of modern physics and a glimpse into the fascinating world of Descartes’ scientific thought. Several of Descartes’ philosophical ideas can be traced back to his scientific interests and thus the book elucidates the motivation behind some of Descartes’ key positions in the area of epistemology and method. In the penultimate chapter the book presents four arguments in favor of seeing Descartes as a physicist on par with Galileo and Newton.

Descartes's Changing Mind

by Peter Machamer J. E. McGuire

Descartes's works are often treated as a unified, unchanging whole. But in Descartes's Changing Mind, Peter Machamer and J. E. McGuire argue that the philosopher's views, particularly in natural philosophy, actually change radically between his early and later works--and that any interpretation of Descartes must take account of these changes. The first comprehensive study of the most significant of these shifts, this book also provides a new picture of the development of Cartesian science, epistemology, and metaphysics. No changes in Descartes's thought are more significant than those that occur between the major works The World (1633) and Principles of Philosophy (1644). Often seen as two versions of the same natural philosophy, these works are in fact profoundly different, containing distinct conceptions of causality and epistemology. Machamer and McGuire trace the implications of these changes and others that follow from them, including Descartes's rejection of the method of abstraction as a means of acquiring knowledge, his insistence on the infinitude of God's power, and his claim that human knowledge is limited to that which enables us to grasp the workings of the world and develop scientific theories.

Descartes's Secret Notebook: A True Tale of Mathematics, Mysticism , and the Quest to Understand the Universe

by Amir D. Aczel

René Descartes (1596–1650) is one of the towering and central figures in Western philosophy and mathematics. His apothegm “Cogito, ergo sum” marked the birth of the mind-body problem, while his creation of so-called Cartesian coordinates have made our physical and intellectual conquest of physical space possible. But Descartes had a mysterious and mystical side, as well. Almost certainly a member of the occult brotherhood of the Rosicrucians, he kept a secret notebook, now lost, most of which was written in code. After Descartes’s death, Gottfried Leibniz, inventor of calculus and one of the greatest mathematicians in history, moved to Paris in search of this notebook—and eventually found it in the possession of Claude Clerselier, a friend of Descartes. Leibniz called on Clerselier and was allowed to copy only a couple of pages—which, though written in code, he amazingly deciphered there on the spot. Leibniz’s hastily scribbled notes are all we have today of Descartes’s notebook, which has disappeared. Why did Descartes keep a secret notebook, and what were its contents? The answers to these questions lead Amir Aczel and the reader on an exciting, swashbuckling journey, and offer a fascinating look at one of the great figures of Western culture.

Descartes-Agonistes

by John Schuster

This book reconstructs key aspects of the early career of Descartes from 1618 to 1633; that is, up through the point of his composing his first system of natural philosophy, Le Monde, in 1629-33. It focuses upon the overlapping and intertwined development of Descartes' projects in physico-mathematics, analytical mathematics, universal method, and, finally, systematic corpuscular-mechanical natural philosophy. The concern is not simply with the conceptual and technical aspects of these projects; but, with Descartes' agendas within them and his construction and presentation of his intellectual identity in relation to them. Descartes' technical projects, agendas and senses of identity shifted over time, entangled and displayed great successes and deep failures, as he morphed from a mathematically competent, Jesuit trained graduate in neo-Scholastic Aristotelianism to aspiring prophet of a systematised corpuscular-mechanism, passing through stages of being a committed physico-mathematicus, advocate of a putative 'universal mathematics', and projector of a grand methodological dream. In all three dimensions--projects, agendas and identity concerns--the young Descartes struggled and contended, with himself and with real or virtual peers and competitors, hence the title 'Descartes-Agonistes'.

Descent: The Heroic Discovery of the Abyss

by Bradford Matsen

Brad Matsen brings to vivid life the famous deep-sea expeditions of Otis Barton and William Beebe. Beebe was a very well-connected and internationally acclaimed naturalist, with the power to generate media attention. Barton was an engineer and heir to a considerable fortune, who had long dreamed of making his mark on the world as an adventurer. Together, Beebe and Barton would achieve what no one had done before--direct observation of life in the blackness of the abyss. Here, against the back drop of the depression, is their riveting tale.

Describing Species: Practical Taxonomic Procedure for Biologists

by Judith Winston

A basic practical manual for the process of describing new species, this desperately needed desk reference and guide to nomenclatural procedure and taxonomic writing serves as a Strunk & White of species description, covering both botanical and zoological codes of nomenclature.

Describing Species: Practical Taxonomic Procedure for Biologists

by Judith Winston

New species are discovered every day—and cataloguing all of them has grown into a nearly insurmountable task worldwide. Now, this definitive reference manual acts as a style guide for writing and filing species descriptions. New collecting techniques and new technology have led to a dramatic increase in the number of species that are discovered. Explorations of unstudied regions and new habitats for almost any group of organisms can result in a large number of new species discoveries—and hence the need to be described. Yet there is no one source a student or researcher can readily consult to learn the basic practical aspects of taxonomic procedures.Species description can present a variety of difficulties: Problems arise when new species are not given names because their discoverers do not know how to write a formal species description or when these species are poorly described. Biologists may also have to deal with nomenclatural problems created by previous workers or resulting from new information generated by their own research. This practical resource for scientists and students contains instructions and examples showing how to describe newly discovered species in both the animal and plant kingdoms.With special chapters on publishing taxonomic papers and on ecology in species description, as well as sections covering subspecies, genus-level, and higher taxa descriptions, Describing Species enhances any writer's taxonomic projects, reports, checklists, floras, faunal surveys, revisions, monographs, or guides.The volume is based on current versions of the International Codes of Zoological and Botanical Nomenclature and recognizes that systematics is a global and multicultural exercise. Though Describing Species has been written for an English-speaking audience, it is useful anywhere Taxonomy is spoken and will be a valuable tool for professionals and students in zoology, botany, ecology, paleontology, and other fields of biology.

Descriptive Archaeoastronomy and Ancient Indian Chronology

by Amitabha Ghosh

This book presents the basic fundamentals of descriptive archaeoastronomy and its application to the astronomical descriptions found in ancient Indian scriptures. Archaeoastronomy is a branch of positional astronomy that helps to determine the epochs of ancient astronomical alignments and special astronomical events. In this book, only the descriptions of special stellar alignments and events found in ancient texts can identify the antiquity of the descriptions. India possesses a large volume of ancient scriptures like Vedas and Puranas which contain many astronomical descriptions as in ancient India positional astronomy was well developed. The antiquities of these texts are determined through archaeoastronomical techniques. Major events like Mahabharata War are dated and using these dates a chronology of ancient India is determined. The astronomically determined chronology is compared with the results from various archaeological, palaeoclimatological, geological and genealogical investigations of ancient India. This introductory book interests readers interested in unveiling the mystery involved with the protohistory of this ancient civilization.

Descriptive Inorganic, Coordination, and Solid State Chemistry

by Glen E. Rodgers

This proven book introduces the basics of coordination, solid-state, and descriptive main-group chemistry in a uniquely accessible manner, featuring a "less is more" approach. Consistent with the "less is more" philosophy, the book does not review topics covered in general chemistry, but rather moves directly into topics central to inorganic chemistry. Written in a conversational prose style that is enjoyable and easy to understand, this book presents not only the basic theories and methods of inorganic chemistry (in three self-standing sections), but also a great deal of the history and applications of the discipline. This edition features new art, more diversified applications, and a new icon system. And to better help readers understand how the seemingly disparate topics of the periodical table connect, the book offers revised coverage of the author's "Network of Interconnected Ideas" on new full color endpapers, as well as on a convenient tear-out card.

Descriptive Taxonomy

by Mark F. Watson Chris H. C. Lyal Colin A. Pendry Mark F. Watson Chris H. C. Lyal

In an age when biodiversity is being lost at an unprecedented rate, it is vital that floristic and faunistic information is up to date, reliable and easily accessible for the formulation of effective conservation strategies. Electronic data management and communication are transforming descriptive taxonomy radically, enhancing both the collection and dissemination of crucial data on biodiversity. This volume is written by scientists at the forefront of current developments of floras and faunas, along with specialists from applied user groups. The chapters review novel methods of research, development and dissemination, which aim to maximise the relevance and impact of data. Regional case studies are used to illustrate the outputs and impacts of taxonomic research. Integrated approaches are presented which have the capacity to accelerate the production of floras and faunas and to better serve the needs of a widening audience.

Desde la eternidad hasta hoy: En busca de la teoría definitiva del tiempo

by Sean Carroll

A partir de la entropía, la física cuántica, los viajes en el tiempo o el significado de la vida, Sean Carroll profundiza en uno de los grandes enigmas de la ciencia: ¿Qué es el tiempo? Hace veinte años Stephen Hawking intentó explicar el tiempo a través de la comprensión del big bang. Ahora, en Desde la eternidad hasta hoy, Sean Carroll, uno de los mejores físicos teóricos del mundo, nos ofrece una teoría revolucionaria que ilustra cómo la flecha del tiempo existe gracias a condiciones previas al big bang, una era con la que Einstein ni siquiera soñó, y que explica que nuestro universo convive con universos paralelos en los que el tiempo viaja en dirección opuesta. Autoridades en el campo de la física teórica opinan... «Una exploración cautivadora de los misterios del tiempo.» Brian Green «Lúcido y profundo.» Kip S. Thome Y la prensa afirma... «Desde la eternidad hasta hoy es una de las mejores explicaciones de los misterios asombrosos de nuestro universo.» The Wall Street Journal «Carroll utiliza un lenguaje coloquial y accesible para explorar los desafíos de la cosmología.» Library Journal

Desde las ruinas del futuro

by Manuel Arias Maldonado

Si queremos evitar futuros sobresaltos, es necesario explicar la crisis y elucidar sus significados. La pandemia de la COVID-19 ha sacudido a la humanidad con una fuerza inopinada: un virus de origen animal ha obligado a los ciudadanos de gran parte del globo a quedarse en casa, y el mundo acelerado de la globalización se ha detenido ante la mirada perpleja de los contemporáneos. Millones de personas han enfermado y cientos de miles han muerto, mientras el uso masivo de las mascarillas nos recordaba a diario que la habitabilidad del planeta no puede darse por supuesta. Así que, un siglo después de la Gripe Española, otro virus infeccioso ha actuado como agente histórico de primer orden. Y esta catástrofe inesperada, mas no imprevista, aguarda ahora a sus intérpretes. Manuel Arias Maldonado se aproxima a la pandemia como al fenómeno polisémico que es: efecto colateral de las relaciones socionaturales y riesgo global que a duraspenas encaja en las categorías dominantes; la acción del virus fuerza a las democracias a operar en condiciones excepcionales dominadas por la incertidumbre. Pero el virus también activa nuevos imaginarios colectivos y reabre el debate sobre un futuro que se presenta menos como promesa que como amenaza. Rehuyendo cualquier tentación profética, el autor defiende la capacidad del viejo pensamiento ilustrado para procesar con éxito este acontecimiento sublime, cuya causa no debe buscarse en el fracaso de la modernidad sino en su carácter asimétrico e inacabado. La crítica ha dicho sobre el autor:«Leer a Arias Maldonado siempre nos ayuda a entender cómo está cambiando el mundo.»Daniel Gascón, Letras Libres «Arias Maldonado no es un politólogo sino un filósofo político. La diferencia entre ambos oficios es la misma que separa al interiorista del arquitecto. Arias es un académico cuya kantiana ambición es toda la que quepa en la consideración científica de la política. Su trabajo trasciende el corral patrio para dialogar con homólogos extranjeros sobre desafíos estructurales de la democracia occidental.»Jorge Bustos, El Cultural
