Grounds for Grounding


Book Description

GROUNDS FOR GROUNDING The first book to cover grounding from the circuit to system and across the entire spectrum of applications Grounds for Grounding provides a complete and thorough approach to the subject of designing electrical and electronic circuits and systems, blending theory and practice to demonstrate how a few basic rules can be applied across a broad range of applications. The authors begin with the basic concepts of Electromagnetic Compatibility (EMC) that are essential for understanding grounding theory and its applications, such as “ground loop,” which is one of the most misunderstood concepts in EMC. Next, they provide an introduction to grounding, including safety grounding, grounding for control of electromagnetic interference, and grounding-related case studies. Subsequent chapter coverage includes: Fundamentals of grounding design Bonding principles Grounding for power distribution and lightning protection systems Grounding in wiring circuits and cable shields Grounding of EMI terminal protection devices Grounding on printed circuit boards Integrated facility and platform grounding system Practical case studies are integrated throughout the book to aid in readers’ comprehension and each chapter concludes with a useful bibliography. Grounds for Grounding is an indispensable resource for electrical and electronic engineers who work with the design of circuits, systems, and facilities.




Book from the Ground


Book Description

A book without words, recounting a day in the life of an office worker, told completely in the symbols, icons, and logos of modern life. Twenty years ago I made Book from the Sky, a book of illegible Chinese characters that no one could read. Now I have created Book from the Ground, a book that anyone can read. —Xu Bing Following his classic work Book from the Sky, the Chinese artist Xu Bing presents a new graphic novel—one composed entirely of symbols and icons that are universally understood. Xu Bing spent seven years gathering materials, experimenting, revising, and arranging thousands of pictograms to construct the narrative of Book from the Ground. The result is a readable story without words, an account of twenty-four hours in the life of “Mr. Black,” a typical urban white-collar worker. Our protagonist's day begins with wake-up calls from a nearby bird and his bedside alarm clock; it continues through tooth-brushing, coffee-making, TV-watching, and cat-feeding. He commutes to his job on the subway, works in his office, ponders various fast-food options for lunch, waits in line for the bathroom, daydreams, sends flowers, socializes after work, goes home, kills a mosquito, goes to bed, sleeps, and gets up the next morning to do it all over again. His day is recounted with meticulous and intimate detail, and reads like a postmodern, post-textual riff on James Joyce's account of Bloom's peregrinations in Ulysses. But Xu Bing's narrative, using an exclusively visual language, could be published anywhere, without translation or explication; anyone with experience in contemporary life—anyone who has internalized the icons and logos of modernity, from smiley faces to transit maps to menus—can understand it.

The Complete Book of Ground Covers


Book Description

Ground covers are widely thought of as utilitarian—we turn to them when we have a problem that needs a solution. How fast will it fill an area? Can we put it into the tight spaces between pavers? How much foot traffic can it withstand? Yet these plants also offer a diverse range of beautiful and intriguing options with a variety of colors, textures, and forms. They can unify a landscape, knit together plantings and hardscape, and add extra layers of beauty, dynamism, and surprise. As a replacement for lawns, they can reduce our use of water, fertilizer, pesticides, herbicides, carbon-based fuels, and transform a yard into a diverse landscape of habitat and food for native insects, birds, and other wildlife. In this meticulously researched reference, nurseryman Gary Lewis profiles more than 4000 ground covers that can perform these roles with aplomb. No matter what kinds of conditions you’re facing—shade, dry soil, heavy clay, excess moisture—there’s a ground cover that will thrive and beautify your garden. Comprehensive, practical, and copiously illustrated, this indispensable volume belongs on the shelf of every designer, landscape architect, and serious gardener.




Metaphysical Grounding


Book Description

Some of the most eminent and enduring philosophical questions concern matters of priority: what is prior to what? What 'grounds' what? Is, for instance, matter prior to mind? Recently, a vivid debate has arisen about how such questions have to be understood. Can the relevant notion or notions of priority be spelled out? And how do they relate to other metaphysical notions, such as modality, truth-making or essence? This volume of new essays, by leading figures in contemporary metaphysics, is the first to address and investigate the metaphysical idea that certain facts are grounded in other facts. An introduction introduces and surveys the debate, examining its history as well as its central systematic aspects. The volume will be of wide interest to students and scholars of metaphysics.




Gaining Ground


Book Description

Why and how Boston was transformed by landmaking. Fully one-sixth of Boston is built on made land. Although other waterfront cities also have substantial areas that are built on fill, Boston probably has more than any city in North America. In Gaining Ground historian Nancy Seasholes has given us the first complete account of when, why, and how this land was created.The story of landmaking in Boston is presented geographically; each chapter traces landmaking in a different part of the city from its first permanent settlement to the present. Seasholes introduces findings from recent archaeological investigations in Boston, and relates landmaking to the major historical developments that shaped it. At the beginning of the nineteenth century, landmaking in Boston was spurred by the rapid growth that resulted from the burgeoning China trade. The influx of Irish immigrants in the mid-nineteenth century prompted several large projects to create residential land—not for the Irish, but to keep the taxpaying Yankees from fleeing to the suburbs. Many landmaking projects were undertaken to cover tidal flats that had been polluted by raw sewage discharged directly onto them, removing the "pestilential exhalations" thought to cause illness. Land was also added for port developments, public parks, and transportation facilities, including the largest landmaking project of all, the airport. A separate chapter discusses the technology of landmaking in Boston, explaining the basic method used to make land and the changes in its various components over time. The book is copiously illustrated with maps that show the original shoreline in relation to today's streets, details from historical maps that trace the progress of landmaking, and historical drawings and photographs.

Uncertain Ground


Book Description

From the National Book Award-winning author of Redeployment and Missionaries, an astonishing fever graph of the effects of twenty years of war in a brutally divided America. When Phil Klay left the Marines a decade ago after serving as an officer in Iraq, he found himself a part of the community of veterans who have no choice but to grapple with the meaning of their wartime experiences—for themselves and for the country. American identity has always been bound up in war—from the revolutionary war of our founding, to the civil war that ended slavery, to the two world wars that launched America as a superpower. What did the current wars say about who we are as a country, and how should we respond as citizens? Unlike in previous eras of war, relatively few Americans have had to do any real grappling with the endless, invisible conflicts of the post-9/11 world; in fact, increasingly few people are even aware they are still going on. It is as if these wars are a dark star with a strong gravitational force that draws a relatively small number of soldiers and their families into its orbit while remaining inconspicuous to most other Americans. In the meantime, the consequences of American military action abroad may be out of sight and out of mind, but they are very real indeed. This chasm between the military and the civilian in American life, and the moral blind spot it has created, is one of the great themes of Uncertain Ground, Phil Klay’s powerful series of reckonings with some of our country’s thorniest concerns, written in essay form over the past ten years. In the name of what do we ask young Americans to kill, and to die? In the name of what does this country hang together? As we see at every turn in these pages, those two questions have a great deal to do with each another, and how we answer them will go a long way toward deciding where our troubled country goes from here.




No Common Ground


Book Description

When it comes to Confederate monuments, there is no common ground. Polarizing debates over their meaning have intensified into legislative maneuvering to preserve the statues, legal battles to remove them, and rowdy crowds taking matters into their own hands. These conflicts have raged for well over a century--but they've never been as intense as they are today. In this eye-opening narrative of the efforts to raise, preserve, protest, and remove Confederate monuments, Karen L. Cox depicts what these statues meant to those who erected them and how a movement arose to force a reckoning. She lucidly shows the forces that drove white southerners to construct beacons of white supremacy, as well as the ways that antimonument sentiment, largely stifled during the Jim Crow era, returned with the civil rights movement and gathered momentum in the decades after the Voting Rights Act of 1965. Monument defenders responded with gerrymandering and "heritage" laws intended to block efforts to remove these statues, but hard as they worked to preserve the Lost Cause vision of southern history, civil rights activists, Black elected officials, and movements of ordinary people fought harder to take the story back. Timely, accessible, and essential, No Common Ground is the story of the seemingly invincible stone sentinels that are just beginning to fall from their pedestals.
