This updated and revised edition of a widely acclaimed and
successful text for undergraduates examines topology of recent
compact surfaces through the development of simple ideas in plane
geometry. Containing over 171 diagrams, the approach allows for a
straightforward treatment of its subject area. It is particularly
attractive for its wealth of applications and variety of
interactions with branches of mathematics, linked with surface
topology, graph theory, group theory, vector field theory, and
plane Euclidean and non-Euclidean geometry.
Since the first publication of this definitive work nearly 40 years ago, this fourth edition has been completely rewritten. Crystallization is used at some stage in nearly all process
industries as a method of production, purification or recovery of
solid materials.
The first part of this text provides an overview of the physics of lasers and it describes some of the more common types of lasers and their applications. The production of laser light requires the formation of a resonant cavity where stimulated emission of radiation occurs. The light produced in this way is intense, coherent and monochromatic. Applications of lasers include CD/DVD players, laser printers and fiber optic communication devices. While these devices depend largely on the monochromaticity and coherence of the light that lasers produce, other well-known applications, such as laser machining and laser fusion depend on the intensity of laser light. The second part of the book describes the phenomenon of Bose-Einstein condensation. These condensates represent a state of matter that exists in some dilute gases at very low temperature as predicted first by Satyendra Nath Bose and Albert Einstein. Bose-Einstein condensates were first observed experimentally in 1995 by Eric Cornell and Carl Wieman at the University of Colorado, and shortly thereafter by Wolfgang Ketterle at the Massachusetts Institute of Technology. The experimental techniques used to create a Bose-Einstein condensate provide an interesting and unconventional application of lasers: the cooling and confinement of a dilute gas at very low temperature.
Open microfluidics - the study of microflows having a boundary with surrounding air - encompasses paper- or thread-based microfluidics, droplet microfluidics and open-channel microfluidics. Open-channel microflow is a flow at the micro-scale, guided by solid structures, and having at least a free boundary (with air or vapor) other than the advancing meniscus. This book is devoted to the study of open-channel microfluidics which, contrary to paper or thread or droplet microfluidics, is still very sparsely documented, but bears many new applications in biology, biotechnology, medicine, material and space sciences. Capillarity being the principal force triggering an open microflow, the principles of capillarity are first recalled. The onset of open-channel microflow is next analyzed and the fundamental notion of generalized Cassie angle - the apparent contact angle which accounts for the presence of air - is presented. The theory of the dynamics of open-channel microflows is then developed, using the notion of averaged friction length, which accounts for the presence of air along the boundaries of the flow domain. Different channel morphologies are studied and geometrical features, such as valves and capillary pumps, are examined. An introduction to two-phase open-channel microflows is also presented, showing that immiscible plugs can be transported by an open-channel flow. Finally, a selection of interesting applications in the domains of space, materials, medicine and biology is provided, showing the potentialities of open-channel microfluidics.
Retaining the introductory flavor of the now classic First Edition,
this revision includes all the latest techniques in the field. New
information on methods of radio tag harnessing, new sections on
satellite tracking techniques and new types of data analysis are
all included. Still the only comprehensive, up-to-date,
introduction to this fundamental technique for wildlife and
behavioral biologists.
Parkinson's disease is a neurological disorder with cardinal motor signs of resting tremor, bradykinesia and lead-pipe rigidity. In addition, many patients display non-motor symptoms, including a diminished sensation of smell, gastrointestinal problems, various disorders of sleep and some cognitive impairment. These clinical features - particularly the motor signs - manifest after a progressive death of many dopaminergic neurones in the brain. Conventional therapies can reduce the signs of the disease, however, the progression of this neuronal demise has proved difficult to slow or stop, and the condition is relentlessly progressive. Hence, there is a real need to develop a treatment that is neuroprotective and slows the pathology of the disease effectively. At present, there are several neuroprotective therapies in the experimental pipeline, but these are for the patients of tomorrow. This book focuses on two therapies that are readily available for the patients of today. They involve the use of exercise and light (i.e. photobiomodulation: the use of red to infrared light therapy on body tissues). Given the heterogeneity of Parkinson's disease in humans, tackling the condition from a range of different angles - with several different therapies - would only serve to enhance the positive outcomes. This book considers the use of exercise and light therapies, proposing that they have the potential to make a powerful "dynamic duo", offering a most effective neuroprotective treatment option to patients.
Semiconductors and Modern Electronics is a brief introduction to the physics behind semiconductor technologies. Chuck Winrich explores the topic of semiconductors from a qualitative approach to understanding the theories and models used to explain semiconductor devices, which is intended to bring the advanced ideas behind semiconductors to a broader audience of students who will not major in physics. Applications of semiconductors are explored and understood through the models developed in the book. Much of the inspiration for this text comes from Winrich's experience teaching a general electronics course to students majoring in business. The goal of that class, and this work, is to bring forward the science behind semiconductors, and then to look at how that science affects the lives of people.
Multigrid presents both an elementary introduction to multigrid
methods for solving partial differential equations and a
contemporary survey of advanced multigrid techniques and real-life
applications.
This third edition of Peter Bernath's successful Spectra of Atoms and Molecules is designed to provide advanced undergraduates and graduate students a working knowledge of the vast field of spectroscopy. Also of interest to chemists, physicists, astronomers, atmospheric scientists, and engineers, this volume emphasizes the fundamental principles of spectroscopy with the primary goal of teaching the interpretation of spectra. Features include a presentation of group theory needed to understand spectroscopy, detailed worked examples and a large number of excellent problems at the end of each chapter. Prof. Bernath provides a large number of diagrams and spectra which have been specifically recorded for this book. Molecular symmetry, matrix representation of groups, quantum mechanics, and group theory are among the topics covered; atomic, rotational, vibrational, electronic and Raman spectra are analyzed. Bernath's clear treatment of the confusing topic of line strengths as needed for quantitative applications is featured. This much-needed new edition has been updated to include the 2010 CODATA revision of physical constants, and a large number of corrections and clarifications. Responding to student requests, the main new feature is the addition of detailed worked examples in each chapter. Spectra of Atoms and Molecules, 3e will help demystify spectroscopy by showing readers the necessary steps in a derivation, as well as the final result.

Foundations of Engineering Acoustics takes the reader on a journey
from a qualitative introduction to the physical nature of sound,
explained in terms of common experience, to mathematical models and
analytical results which underlie the techniques applied by the
engineering industry to improve the acoustic performance of their
products. The book is distinguished by extensive descriptions and
explanations of audio-frequency acoustic phenomena and their
relevance to engineering, supported by a wealth of diagrams, and by
a guide for teachers of tried and tested class demonstrations and
laboratory-based experiments.
The nuclear Nonproliferation Treaty (NPT) is the cornerstone of nonproliferation and disarmament efforts, yet its negotiation and success was not inevitable. This book aims to address the developments that led to the negotiation of the treaty, examine its implementation, and address challenges that the NPT faces going forward. It begins with an overview of precursor efforts to establish international limits on nuclear weapons and why these efforts failed. It also looks at the changes in the political environment and technical advances, which together increased the threat of proliferation and drove states to negotiate the NPT. The second chapter considers the negotiation of the treaty itself and looks at the gap between US and Soviet positions on key areas like alliance control of nuclear weapons, and how the two governments found common ground on nonproliferation language. It also explores the critical role played by the non-aligned movement to push inclusion of disarmament provisions that would become the foundation for Article VI of the treaty and the hesitancy of nuclear-armed states to support disbarment language and timelines. Chapter 3 of the book focuses on implementation of the NPT and its initial successes in heading off states with nuclear weapons research programs. It addresses how the treaty responded to challenges like the dissolution of the Soviet Union and gaps identified by the illicit nuclear weapons programs in Iraq and North Korea in the early 1990s. Chapter 3 also includes a section on the debate in 1995 over extending the treaty indefinitely, and the compromises reached to satisfy the concerns of the non-nuclear weapon states. Finally, Chapter 4 addresses some of the outstanding challenges to the NPT that remain unresolved, such as the continued failure to convene a conference on the Middle East WMD-free zone and specify the consequences of withdrawing from the NPT, and repurposing civilian nuclear technology transferred under the treaty weapons purposes. It also looks at how the ban treaty under negotiations in the United Nations will support or undermine the NPT's objectives.
In the 1950s, John Reber convinced many Californians that the best
way to solve the state's water shortage problem was to dam up the
San Francisco Bay. Against massive political pressure, Reber's
opponents persuaded lawmakers that doing so would lead to disaster.
They did this not by empirical measurement alone, but also through
the construction of a model. Simulation and Similarity explains why
this was a good strategy while simultaneously providing an account
of modeling and idealization in modern scientific practice. Michael
Weisberg focuses on concrete, mathematical, and computational
models in his consideration of the nature of models, the practice
of modeling, and nature of the relationship between models and
real-world phenomena.
Nanogels are three-dimensional nanosized networks that are formed by physically or chemically cross-linking polymers. They have been explored as a drug-delivery system due to their biocompatibility, high stability, particle-size adjustment, drug-loading capability and modification of the surface for active targeting by cognate receptors on the target cells of tissues. Nanogels can respond to stimuli such as pH, temperature, light and redox, which results in the controlled release of drugs and targeting of site by environmental stimuli and prevents accumulation in non-target tissues, minimizing the side effects of the drug. This book aims to provide a general introduction to nanogels and the design of various stimuli-sensitive nanogels that can control drug release in response to specific stimuli.
A venerable tradition in the metaphysics of science commends ontological reduction: the practice of analysis of theoretical entities into further and further proper parts, with the understanding that the original entity is nothing but the sum of these. This tradition implicitly subscribes to the principle that all the real action of the universe (also referred to as its "causation") happens at the smallest scales-at the scale of microphysics. A vast majority of metaphysicians and philosophers of science, covering a wide swath of the spectrum from reductionists to emergentists, defend this principle. It provides one pillar of the most prominent theory of science, to the effect that the sciences are organized in a hierarchy, according to the scales of measurement occupied by the phenomena they study. On this view, the fundamentality of a science is reckoned inversely to its position on that scale. This venerable tradition has been justly and vigorously countered-in physics, most notably: it is countered in quantum theory, in theories of radiation and superconduction, and most spectacularly in renormalization theories of the structure of matter. But these counters-and the profound revisions they prompt-lie just below the philosophical radar. This book illuminates these counters to the tradition principle, in order to assemble them in support of a vaster (and at its core Aristotelian) philosophical vision of sciences that are not organized within a hierarchy. In so doing, the book articulates the principle that the universe is active at absolutely all scales of measurement. This vision, as the book shows, is warranted by philosophical treatment of cardinal issues in the philosophy of science: fundamentality, causation, scientific innovation, dependence and independence, and the proprieties of explanation.
Paleomagnetism is the study of the fossil magnetism in rocks. It
has been paramount in determining that the continents have drifted
over the surface of the Earth throughout geological time. The
fossil magnetism preserved in the ocean floor has demonstrated how
continental drift takes place through the process of sea-floor
spreading. The methods and techniques used in paleomagnetic studies
of continental rocks and of the ocean floor are described and then
applied to determining horizontal movements of the Earth's crust
over geological time. An up-to-date review of global paleomagnetic
data enables 1000 million
In a groundbreaking examination of the antislavery origins of liberal Protestantism, Molly Oshatz contends that the antebellum slavery debates forced antislavery Protestants to adopt an historicist understanding of truth and morality. Unlike earlier debates over slavery, the antebellum slavery debates revolved around the question of whether or not slavery was a sin in the abstract. Unable to use the letter of the Bible to answer the proslavery claim that slavery was not a sin in and of itself, antislavery Protestants, including William Ellery Channing, Francis Wayland, Moses Stuart, Leonard Bacon, and Horace Bushnell, argued that biblical principles opposed slavery and that God revealed slavery's sinfulness through the gradual unfolding of these principles. Although they believed that slavery was a sin, antislavery Protestants' sympathy for individual slaveholders and their knowledge of the Bible made them reluctant to denounce all slaveholders as sinners. In order to reconcile slavery's sinfulness with their commitments to the Bible and to the Union, antislavery Protestants defined slavery as a social rather than an individual sin. Oshatz demonstrates that the antislavery notions of progressive revelation and social sin had radical implications for Protestant theology. Oshatz carries her study through the Civil War to reveal how emancipation confirmed for northern Protestants the antislavery notion that God revealed His will through history. She describes how after the war, a new generation of liberal theologians, including Newman Smyth, Charles Briggs, and George Harris, drew on the example of antislavery and emancipation to respond to evolution and historical biblical criticism. The theological innovations rooted in the slavery debates came to fruition in liberal Protestantism's acceptance of the historical and evolutionary nature of religious truth.
This is the fifth volume of "Advances in Sonochemistry" the first
having been published in 1990. The definition of sonochemistry has
developed to include not only the ways in which ultrsound has been
harnessed to effect chemistry but also its uses in material
processing. Subjects included range from chemical dosimetry to
ultrasound in microbiology to ultrasound in the extraction of plant
materials and in leather technology.

Intended a both a textbook and a reference, Fourier Acoustics
develops the theory of sound radiation uniquely from the viewpoint
of Fourier Analysis. This powerful perspective of sound radiation
provides the reader with a comprehensive and practical
understanding which will enable him or her to diagnose and solve
sound and vibration problems in the 21st Century. As a result of
this perspective, Fourier Acoustics is able to present thoroughly
and simply, for the first time in book form, the theory of
nearfield acoustical holography, an important technique which has
revolutionised the measurement of sound. Relying little on material
outside the book, Fourier Acoustics will be invaluable as a
graduate level text as well as a reference for researchers in
academia and industry.
The sea is steadily rising, presently at 3.4 mm per year, and it is already costing billions in Venice, on the Thames river and in New York City, to counter sea-level-related surges. Experts anticipate an accelerated rise, and credible predictions for sea-level rise by the year 2100 range from 12 inches to above six feet. Study of the Earth's geologic history, through ice-core samples, links sea-level rise to temperature rise. Since the lifetime of carbon dioxide in the atmosphere is measured in centuries, and it has upset the balance of incoming and outgoing energy, the Earth's temperature will continue to rise, even if carbon burning ceases. Engineering the Earth's solar input appears increasingly attractive and practical as a means to lower the Earth's temperature and, thus, to lower the sea level. The cost of engineering the climate appears small; comparable, even, to the already-incurred costs of sea-level rise represented by civil engineering projects in London, Venice and New York City. Feasible deployment of geoengineering, accompanied by some reduction in carbon burning, is predicted to lower the sea level by the order of one foot by 2100, which negates the expected rise and would provide an immense economic benefit. The accompanying lower global temperature would reduce the severity of extreme weather and restore habitability to lethally hot parts of the world.
Elements of Photoionization Quantum Dynamics Methods focuses on the RMT approach for multiphoton quantum dynamics, which is employed to tackle the problem of laser-induced atomic dynamics. This recently developed formulation has shown the potential to become one of the mainstream ab initio theoretical approaches capable of describing the quantum dynamics of multielectron quantum systems exposed in ultrashort intense laser pulses lasting at the femtosecond timescale ( 10-15 sec). The method itself builds on the division-of-space concept and has evolved as an extension of the well-established atomic R-matrix method to incorporate time in its formulation. It is this way that its name was inherited, R-matrix with time incorporation (RMT), although no R-matrix appears anywhere in the formulation. |
