Troubleshooting Rotating Machinery: Including Centrifugal Pumps and Compressors, Reciprocating Pumps and Compressors, Fans, Steam Turbines, Electric Motors, and More

by Robert X. Perez Andrew P. Conkey

Process machines are critical to the profitability of processes. Safe, efficient and reliable machines are required to maintain dependable manufacturing processes that can create saleable, on-spec product on time, and at the desired production rate. As the wards of process machinery, we wish to keep our equipment in serviceable condition. One of the most challenging aspects of a machinery professional or operator's job is deciding whether an operating machine should be shut down due to a perceived problem or be allowed to keep operating. If he or she wrongly recommends a repair be conducted, the remaining useful machine life is wasted, but if he or she is right, they can save the organization from severe consequences, such as product releases, fires, costly secondary machine damage, etc. This economic balancing act is at the heart of all machinery assessments. Troubleshooting is part science and part art. Simple troubleshooting tables or decision trees are rarely effective in solving complex, real-world machine problems. For this reason, the authors want to offer a novel way to attack machinery issues that can adversely affect the reliability and efficiency of your plant processes. The methodology presented in this book is not a rigid "cook book" approach but rather a flexible and dynamic process aimed at exploring process plant machines holistically, in order uncover the true nature the problem at hand.

Troubleshooting Vacuum Systems

by Norman P. Lieberman

Vacuum systems are in wide spread use in the petrochemical plants, petroleum refineries and power generation plants. <P><P>The existing texts on this subject are theoretical in nature and only deal with how the equipment functions when in good mechanical conditions, from the viewpoint of the equipment vendor. In this much-anticipated volume, one of the most well-respected and prolific process engineers in the world takes on troubleshooting vacuum systems, and especially steam ejectors, an extremely complex and difficult subject that greatly effects the profitability of the majority of the world's refineries.

A Troublesome Inheritance: Genes, Race and Human History

by Nicholas Wade

Drawing on startling new evidence from the mapping of the genome, an explosive new account of the genetic basis of race and its role in the human story Fewer ideas have been more toxic or harmful than the idea of the biological reality of race, and with it the idea that humans of different races are biologically different from one another. For this understandable reason, the idea has been banished from polite academic conversation. Arguing that race is more than just a social construct can get a scholar run out of town, or at least off campus, on a rail. Human evolution, the consensus view insists, ended in prehistory.Inconveniently, as Nicholas Wade argues in A Troublesome Inheritance, the consensus view cannot be right. And in fact, we know that populations have changed in the past few thousand years--to be lactose tolerant, for example, and to survive at high altitudes. Race is not a bright-line distinction; by definition it means that the more human populations are kept apart, the more they evolve their own distinct traits under the selective pressure known as Darwinian evolution. For many thousands of years, most human populations stayed where they were and grew distinct, not just in outward appearance but in deeper senses as well.Wade, the longtime journalist covering genetic advances for The New York Times, draws widely on the work of scientists who have made crucial breakthroughs in establishing the reality of recent human evolution. The most provocative claims in this book involve the genetic basis of human social habits. What we might call middle-class social traits--thrift, docility, nonviolence--have been slowly but surely inculcated genetically within agrarian societies, Wade argues. These "values" obviously had a strong cultural component, but Wade points to evidence that agrarian societies evolved away from hunter-gatherer societies in some crucial respects. Also controversial are his findings regarding the genetic basis of traits we associate with intelligence, such as literacy and numeracy, in certain ethnic populations, including the Chinese and Ashkenazi Jews.Wade believes deeply in the fundamental equality of all human peoples. He also believes that science is best served by pursuing the truth without fear, and if his mission to arrive at a coherent summa of what the new genetic science does and does not tell us about race and human history leads straight into a minefield, then so be it. This will not be the last word on the subject, but it will begin a powerful and overdue conversation.From the Trade Paperback edition.

Troublesome Science: The Misuse of Genetics and Genomics in Understanding Race (Race, Inequality, and Health #2)

by Rob DeSalle Ian Tattersall

It is well established that all humans today, wherever they live, belong to one single species. Yet even many people who claim to abhor racism take for granted that human “races” have a biological reality. In Troublesome Science, Rob DeSalle and Ian Tattersall provide a lucid and forceful critique of how scientific tools have been misused to uphold misguided racial categorizations.DeSalle and Tattersall argue that taxonomy, the scientific classification of organisms, provides an antidote to the myth of race’s biological basis. They explain how taxonomists do their science—how to identify a species and to understand the relationships among different species and the variants within them. DeSalle and Tattersall also detail the use of genetic data to trace human origins and look at how scientists have attempted to recognize discrete populations within Homo sapiens. Troublesome Science demonstrates conclusively that modern genetic tools, when applied correctly to the study of human variety, fail to find genuine differences. While the diversity that exists within our species is a real phenomenon, it nevertheless defeats any systematic attempt to recognize discrete units within it. The stark lines that humans insist on drawing between their own groups and others are nothing but a mixture of imagination and ideology. Troublesome Science is an important call for researchers, journalists, and citizens to cast aside the belief that race has a biological meaning, for the sake of social justice and sound science alike.

A Truck Full of Money: One Man's Quest to Recover from Great Success

by Tracy Kidder

"A perfectly executed, exquisitely reported parable of the Internet age and the wild, mad adventure that is start-up culture."--Charles Duhigg Fortune, mania, genius, philanthropy--the bestselling author of Mountains Beyond Mountains gives us the inspiring story of Paul English, the founder of Kayak.com and Lola. Tracy Kidder, the "master of the nonfiction narrative" (The Baltimore Sun) and author of the bestselling classic The Soul of a New Machine, now tells the story of Paul English, a kinetic and unconventional inventor and entrepreneur, who as a boy rebelled against authority. Growing up in working-class Boston, English discovers a medium for his talents the first time he sees a computer. As a young man, despite suffering from what would eventually be diagnosed as bipolar disorder, he begins his pilgrim's journey through the ups and downs in the brave new world of computers. Relating to the Internet as if it's an extension of his own mind, he discovers that he has a talent for conceiving innovative enterprises and building teams that can develop them, becoming "a Pied Piper" of geeks. His innovative management style, success, and innate sense of fair play inspire intense loyalty. Early on, one colleague observes: "Someday this boy's going to get hit by a truck full of money, and I'm going to be standing beside him." Yet when English does indeed make a fortune, when the travel website Kayak is sold for almost two billion dollars--the first thing he thinks about is how to give the money away: "What else would you do with it?" The second thing he thinks is, What's next? With the power of a consummate storyteller, Tracy Kidder casts a fresh, critical, and often humorous eye on the way new ideas and new money are reshaping our culture and the world. A Truck Full of Money is a mesmerizing portrait of an irresistibly endearing man who is indefatigable, original, and as unpredictable as America itself. Advance praise for A Truck Full of Money"A perfectly executed, exquisitely reported parable of the Internet age, and the wild, mad adventure that is start-up culture."--Charles Duhigg "A Truck Full of Money brings us into unknown spaces of the complex workings of the mind--of a brilliant software engineer, of this new decade, of the brutal/fast business of technology, of stunning privilege, and of one man's efforts to put his fortune to humane use."--Adrian Nicole LeBlanc"The story of [an] entrepreneur's remarkable life [and] the new American economy and the technological world that built it. More engrossing work from a gifted practitioner of narrative nonfiction."--Kirkus ReviewsFrom the Hardcover edition.

True Bugs (Heteroptera) of the Neotropics

by Antônio R. Panizzi Jocélia Grazia

True bugs (Heteroptera) are a diverse and complex group of plant-feeding and predatory insects important to food production, human health, the global economy and the environment. Within the nearly 43,000 species described around the world, Neotropical true bugs are particularly diverse, and much remains to be discovered about their biology and relations with other species. Inspired by the need for a comprehensive assessment, True Bugs (Heteroptera) of the Neotropics is the most complete and thorough review ever published. Experts in each of the seven infraorders have drawn together the scattered literature to provide detailed treatments of each major taxon. The most common and important species as well as select lesser known species in each major family are covered, highlighting morphology, classification, biology and ecology. The numerous color illustrations highlight key species and their adaptations, and importance to basic and applied sciences is discussed. Each chapter is based on an up-to-date review of the literature, and with a bibliography of more than 3,000 references, readers are presented with an unprecedented and vital and timely account of the true bugs of the Neotropical Region.

True Cost Accounting for Food: Balancing the Scale (Routledge Studies in Food, Society and the Environment)

by Barbara Gemmill-Herren

This book explains how True Cost Accounting is an effective tool we can use to address the pervasive imbalance in our food system. Calls are coming from all quarters that the food system is broken and needs a radical transformation. A system that feeds many yet continues to create both extreme hunger and diet-related diseases, and one which has significant environmental impacts, is not serving the world adequately. This volume argues that True Cost Accounting in our food system can create a framework for a systemic shift. What sounds on the surface like a practice relegated to accountants is ultimately a call for a new lens on the valuation of food and a new relationship with the food we eat, starting with the reform of a system out of balance. From the true cost of corn, rice and water, to incentives for soil health, the chapters economically compare conventional and regenerative, more equitable farming practices in and food system structures, including taking an unflinching look at the true cost of cheap labour. Overall, this volume points towards the potential for our food system to be more human-centred than profit-centred and one that has a more respectful relationship to the planet. It sets forth a path forward based on True Cost Accounting for food. This path seeks to fix our current food metrics, in policy and in practice, by applying a holistic lens that evaluates the actual costs and benefits of different food systems, and the impacts and dependencies between natural systems, human systems, agriculture and food systems. This volume is essential reading for professionals and policymakers involved in developing and reforming the food system, as well as students and scholars working on food policy, food systems and sustainability.

The True Creator of Everything: How the Human Brain Shaped the Universe as We Know It

by Miguel Nicolelis

A radically new cosmological view from a groundbreaking neuroscientist placing the human brain at the center of humanity’s universe Renowned neuroscientist Miguel Nicolelis introduces readers to a revolutionary new theory of how the human brain evolved to become an organic computer without rival in the known universe. Nicolelis undertakes the first attempt to explain the entirety of human history, culture, and civilization based on a series of recently uncovered key principles of brain function. This new cosmology is centered around three fundamental properties of the human brain: its insurmountable malleability to adapt and learn; its exquisite ability to allow multiple individuals to synchronize their minds around a task, goal, or belief; and its incomparable capacity for abstraction. Combining insights from such diverse fields as neuroscience, mathematics, evolution, computer science, physics, history, art, and philosophy, Nicolelis presents a neurobiologically based manifesto for the uniqueness of the human mind and a cautionary tale of the threats that technology poses to present and future generations.

True Enough

by Catherine Z. Elgin

The development of an epistemology that explains how science and art embody and convey understanding. Philosophy valorizes truth, holding that there can never be epistemically good reasons to accept a known falsehood, or to accept modes of justification that are not truth conducive. How can this stance account for the epistemic standing of science, which unabashedly relies on models, idealizations, and thought experiments that are known not to be true? In True Enough, Catherine Elgin argues that we should not assume that the inaccuracy of models and idealizations constitutes an inadequacy. To the contrary, their divergence from truth or representational accuracy fosters their epistemic functioning. When effective, models and idealizations are, Elgin contends, felicitous falsehoods that exemplify features of the phenomena they bear on. Because works of art deploy the same sorts of felicitous falsehoods, she argues, they also advance understanding. Elgin develops a holistic epistemology that focuses on the understanding of broad ranges of phenomena rather than knowledge of individual facts. Epistemic acceptability, she maintains, is a matter not of truth-conduciveness, but of what would be reflectively endorsed by the members of an idealized epistemic community—a quasi-Kantian realm of epistemic ends.

True Genius: The Life And Science Of John Bardeen

by Lillian Hoddeson Vicki Daitch

What is genius? Define it. Now think of scientists who embody the concept of genius. Does the name John Bardeen spring to mind? Indeed, have you ever heard of him?Like so much in modern life, immediate name recognition often rests on a cult of personality. We know Einstein, for example, not just for his tremendous contributions to science, but also because he was a character, who loved to mug for the camera. And our continuing fascination with Richard Feynman is not exclusively based on his body of work; it is in large measure tied to his flamboyant nature and offbeat sense of humor.These men, and their outsize personalities, have come to erroneously symbolize the true nature of genius and creativity. We picture them born brilliant, instantly larger than life. But is that an accurate picture of genius? What of others who are equal in stature to these icons of science, but whom history has awarded only a nod because they did not readily engage the public? Could a person qualify as a bona fide genius if he was a regular Joe?The answer may rest in the story of John Bardeen.John Bardeen was the first person to have been awarded two Nobel Prizes in the same field. He shared one with William Shockley and Walter Brattain for the invention of the transistor. But it was the charismatic Shockley who garnered all the attention, primarily for his Hollywood ways and notorious views on race and intelligence.Bardeen&rsquo;s second Nobel Prize was awarded for the development of a theory of superconductivity, a feat that had eluded the best efforts of leading theorists&mdash;including Albert Einstein, Neils Bohr, Werner Heisenberg, and Richard Feynman. Arguably, Bardeen&rsquo;s work changed the world in more ways than that of any other scientific genius of his time. Yet while every school child knows of Einstein, few people have heard of John Bardeen. Why is this the case?Perhaps because Bardeen differs radically from the popular stereotype of genius. He was a modest, mumbling Midwesterner, an ordinary person who worked hard and had a knack for physics and mathematics. He liked to picnic with his family, collaborate quietly with colleagues, or play a round of golf. None of that was newsworthy, so the media, and consequently the public, ignored him.John Bardeen simply fits a new profile of genius. Through an exploration of his science as well as his life, a fresh and thoroughly engaging portrait of genius and the nature of creativity emerges. This perspective will have readers looking anew at what it truly means to be a genius.

True Genius: The Life and Work of Richard Garwin, the Most Influential Scientist You've Never Heard of

by Joel Shurkin

Richard Garwin was awarded the Presidential Medal of Freedom by President Barack Obama Called a "true genius" by Enrico Fermi, Richard Garwin has influenced modern life in far-reaching ways, yet he is hardly known outside the physics community. This is the first biography of one of America's great minds--a top physicist, a brilliant technological innovator, and a trusted advisor of presidents for sixty years. Among his many contributions to modern technology are innovations we now take for granted: air-traffic control systems, touch screens, color monitors, laser printers, GPS satellite navigation, and many other facets of everyday contemporary life.But certainly his most important work has been on behalf of nuclear disarmament. As a key member of the Los Alamos team that developed the hydrogen bomb (he created the final design), Garwin subsequently devoted much of his career to ensuring that nuclear weapons never again be used. He has spent hundreds of hours testifying before Congress, serving on government advisory committees, and doing work that is still classified, all the while working for IBM as a researcher. A genuine polymath, his ideas extend from propulsion systems for interplanetary flight to preventing flu epidemics. Never shy about offering his opinions, even to rigid government bureaucracies unwilling to change, Garwin continues to show leaders how to do the smart thing. The world is a more interesting and safer place because of his many accomplishments.

True Roots: What Quitting Hair Dye Taught Me about Health and Beauty

by Ronnie Citron-Fink

Like 75% of American women, Ronnie Citron-Fink dyed her hair, visiting the salon every few weeks to hide gray roots in her signature dark brown mane. She wanted to look attractive, professional, young. Yet as a journalist covering health and the environment, she knew something wasn't right. All those unpronounceable chemical names on the back of the hair dye box were far from natural. Were her recurring headaches and allergies telltale signs that the dye offered the illusion of health, all the while undermining it?So after twenty-five years of coloring, Ronnie took a leap and decided to ditch the dye. Suddenly everyone, from friends and family to rank strangers, seemed to have questions about her hair. How'd you do it? Are you doing that on purpose? Are you OK? Armed with a mantra that explained her reasons for going gray—the upkeep, the cost, the chemicals—Ronnie started to ask her own questions.What are the risks of coloring? Why are hair dye companies allowed to use chemicals that may be harmful? Are there safer alternatives? Maybe most importantly, why do women feel compelled to color? Will I still feel like me when I have gray hair?True Roots follows Ronnie's journey from dark dyes to a silver crown of glory, from fear of aging to embracing natural beauty. Along the way, readers will learn how to protect themselves, whether by transitioning to their natural color or switching to safer products. Like Ronnie, women of all ages can discover their own hair story, one built on individuality, health, and truth.

The True Story of Modern Cosmology: Origins, Main Actors and Breakthroughs

by Emilio Elizalde

This book tells the story of how, over the past century, dedicated observers and pioneering scientists achieved our current understanding of the universe. It was in antiquity that humankind first attempted to explain the universe often with the help of myths and legends. This book, however, focuses on the time when cosmology finally became a true science. As the reader will learn, this was a slow process, extending over a large part of the 20th century and involving many astronomers, cosmologists and theoretical physicists. The book explains how empirical astronomical data (e.g., Leavitt, Slipher and Hubble) were reconciled with Einstein's general relativity; a challenge which finally led Friedmann, De Sitter and Lemaître, and eventually Einstein himself, to a consistent understanding of the observational results. The reader will realize the extraordinary implications of these achievements and how deeply they changed our vision of the cosmos: From being small, static, immutable and eternal, it became vast and dynamical - originating from (almost) nothing, and yet now, nearly 14 billion years later, undergoing accelerated expansion. But, as always happens, as well as precious knowledge, new mysteries have also been created where previously absolute certainty had reigned.
