The Acoustic Bubble describes the interaction of acoustic fields with bubbles in liquid. The book consists of five chapters. Chapter 1 provides a basic introduction to acoustics, including some of the more esoteric phenomena that can be seen when high-frequency high-intensity underwater sound is employed. Chapter 2 discusses the nucleation of cavitation and basic fluid dynamics, while Chapter 3 draws together the acoustics and bubble dynamics to discuss the free oscillation of a bubble and acoustic emissions from such activity. The acoustic probes that are often applied to study the behavior of a bubble when an externally-applied acoustic field drives it into oscillation is deliberated in Chapter 4. The last chapter outlines a variety of effects associated with acoustically-induced bubble activity. The bubble detection, sonoluminescence, sonochemistry, and pulse enhancement are also covered. This publication is a good reference for physics and engineering students and researchers intending to acquire knowledge of the acoustic interactions of acoustic fields with bubbles.

This book closes the gap between Chemical Reaction Engineering and Fluid Mechanics. It provides the basic theory for momentum, heat and mass transfer in reactive systems. Numerical methods for solving the resulting equations as well as the interplay between physical and numerical modes are discussed. The book is written using the standard terminology of this community. It is intended for researchers and engineers who want to develop their own codes, or who are interested in a deeper insight into commercial CFD codes in order to derive consistent extensions and to overcome "black box" practice. It can also serve as a textbook and reference book.

For over fifteen years, New York Times bestselling author Harry S. Dent, Jr., has been uncannily accurate in predicting the financial future. In his three previous works, Dent predicted the financial recession of the early nineties, the economic expansion of the mid-nineties, and the financial free-for-all of 1998-2000. The Next Great Bubble Boom -- part crystal ball, part financial planner -- offers a comprehensive forecast for the next two decades, showing new models for predicting the future behavior of the economy, inflation, large- and small-cap stocks, bonds, key sectors, and so on. In taking a look at past booms and busts, Dent compares our current state to that of the crash of 1920-21, and the years ahead of us to the Roaring Twenties. Dent gives advice on everything from investment strategies to real estate cycles, and shows not only how bright our future will be but how best to profit from it. Dent gives us all something to look forward to, including: The Dow hitting 40,000 by the end of the decade The Nasdaq advancing at least ten times from its October 2001 lows to around 13,500, and potentially as high as 20,000 by 2009 Another strong advance in stocks in 2005, with a significant correction into around September/October 2006 The Great Boom resurging into its final and strongest stage in 2007, and even more fully in 2008, lasting until late 2009 to early 2010 Dent's amazing ability to track and forecast our financial future is renowned, and here he takes that ability to the next level, showing not only what our economy will look like but also how it will affect us as individuals, as organizations, and as a culture. From the upcoming wealth revolution to the essential principles of entrepreneurial success, the book describes a new society where economic and philanthropic development go hand in hand. In The Next Great Bubble Boom, Dent shows not only how the economic growth of the late 1990s was a prelude to the true great boom right around the corner but how all of us can reap its benefits.

A IUTAM (International Union of Theoretical and Applied Mechanics) Sympo sium 'Mechanics and Physics of Bubbles in Liquids' was held at Pasadena, Calif., USA from 15 through 19 June 1981. The present volume contains the printed version of nearly all papers read at the Symposium. The study of the behaviour of bubbles in liquids was originally stimu lated by problems in cavitation and in boiling ofliquids. Today research is initiated by problems in many other fields as well. In this respect a growing interest from the side of biomechanics may be mentioned. Ordering of the papers could be done either according to the various mechanical and physical aspects of the subject or according to the fields of application. The presentaton at the Symposium contained a bit of both; there was a session on physico-chemical aspects for example and also a session on biological applications. The subdivision in this volume follows roughly the sessions in the Symposium. Most of them start with a paper of a survey nature, reporting progress made in recent years. Here, as in other fields of engineering science, one notes the important part played by experimental techniques and by numerical analysis.

From The Outer Heliosphere To The Local Bubble

Knowledge about the outer heliosphere and the interstellar medium, which were long treated as two separate fields, has improved dramatically over the past 25 years as a consequence of recent developments: The discovery of interstellar pickup ions and neutral helium inside the heliosphere, the determination of the interstellar hydrogen distribution in the heliosphere obtained using backscattered solar Lyman-alpha radiation, the prediction and subsequent detection of the hydrogen wall just outside of the heliopause, the development of detailed global models for the interaction of solar wind plasma with the interstellar medium, and most recently, direct in-situ plasma and field measurements inside of the heliosheath. At the same time, our understanding of the nearby galactic environment, including the composition and dynamics of the warm gas clouds and hot gas in the local bubble, has benefited greatly from absorption-line spectroscopy using nearby stars as background sources and dynamic modeling. The present volume provides a synopsis of these developments organised into seven sections: Dominant physical processes in the termination shock and heliosheath, three-dimensional shape and structure of the dynamic heliosphere, relation of the plasmas and dust inside and outside of the heliosphere, origin and properties of the very local interstellar medium, energy and pressure equilibria in the local bubble, physical processes in the multiphase interstellar medium inside of the local bubble, and the roles that magnetic fields play in the outer heliosphere and the local bubble. The last theme is probably the most basic of all as magnetic fields play important roles in most of the phenomena discussed here. The volume concludes with four papers providing the "big picture" by looking at the time evolution of both the heliosphere and the local bubble, looking beyond the local bubble, and finally addressing the challenges in modeling the interface between the two media.

Multiple-choice testing is an educational reality. Rather than complain about the negative impact these tests may have on teaching and learning, why not use them to better understand your students' true mathematical knowledge and comprehension? Maryann Wickett and Eunice Hendrix-Martin show teachers how to move beyond the student's answer--right or wrong--to uncover understanding and/or misconceptions. By asking a few simple follow-up questions, teachers can learn a great deal about student understanding and make better, more informed instructional decisions. The Beyond the Bubble books (grades 2-3 and grades 4-5) are each divided into five strands--number, measurement, algebra, geometry, and probability--with six problems per strand. Each problem includes an overview of the objective of the test question, a sample question, typical of those found on standardized tests, strategies students employ to solve the problem, conversation starters, student work, student-teacher conversations, and instructional strategies to advance student learning. Teachers will also find suggestions for differentiation, reproducible of sample questions, and a comprehensive list of additional resources. With dozens of sample test questions and numerous student samples, Beyond the Bubble shows educators how to use multiple choice tests to provide more purposeful, focused mathematics instruction for all of their students.

An eye-opening account of how the hidden rise of personalization on the Internet is controlling-and limiting-the information we consume. In December 2009, Google began customizing its search results for each user. Instead of giving you the most broadly popular result, Google now tries to predict what you are most likely to click on. According to MoveOn.org board president Eli Pariser, Google's change in policy is symptomatic of the most significant shift to take place on the Web in recent years-the rise of personalization. In this groundbreaking investigation of the new hidden Web, Pariser uncovers how this growing trend threatens to control how we consume and share information as a society-and reveals what we can do about it. Though the phenomenon has gone largely undetected until now, personalized filters are sweeping the Web, creating individual universes of information for each of us. Facebook-the primary news source for an increasing number of Americans-prioritizes the links it believes will appeal to you so that if you are a liberal, you can expect to see only progressive links. Even an old-media bastion like The Washington Post devotes the top of its home page to a news feed with the links your Facebook friends are sharing. Behind the scenes a burgeoning industry of data companies is tracking your personal information to sell to advertisers, from your political leanings to the color you painted your living room to the hiking boots you just browsed on Zappos. In a personalized world, we will increasingly be typed and fed only news that is pleasant, familiar, and confirms our beliefs-and because these filters are invisible, we won't know what is being hidden from us. Our past interests will determine what we are exposed to in the future, leaving less room for the unexpected encounters that spark creativity, innovation, and the democratic exchange of ideas. While we all worry that the Internet is eroding privacy or shrinking our attention spans, Pariser uncovers a more pernicious and far- reaching trend on the Internet and shows how we can- and must-change course. With vivid detail and remarkable scope, The Filter Bubble reveals how personalization undermines the Internet's original purpose as an open platform for the spread of ideas and could leave us all in an isolated, echoing world.
