Faber & Faber MINI The True and Secret History of the Making of
Book SynopsisIn 1959, the first Mini was produced on an assembly line at Cowley, near Oxford. It would take a team of supremely talented designers, engineers and production-line workers to build a car that was unique in appearance and construction. They would clash over an uncomfortable and unsafe prototype, and the public had to be convinced to buy a car that let in water when it rained. But somehow the Mini became an icon. Designed for austerity and efficiency, the car came to represent individuality and classlessness.Today, the car is still produced at Cowley - it is now owned by BMW and called the MINI. A great British manufacturing story, it is more popular throughout the world than it has ever been, a symbol of the age that created it. But who makes these things, and what do they think about their work? By meeting the people behind the MINI, Simon Garfield uncovers a fascinating story of endeavour, ingenuity and masterful marketing. The modern MINI has come a long way from the leak

The History Press Ltd Machines Behaving Badly
Book SynopsisCan we build moral machines?Artificial intelligence is an essential part of our lives for better or worse. It can be used to influence what we buy, who gets shortlisted for a job and even how we vote. Without AI, medical technology wouldn't have come so far, we'd still be getting lost in our GPS-free cars, and smartphones wouldn't be so, well, smart. But as we continue to build more intelligent and autonomous machines, what impact will this have on humanity and the planet?Professor Toby Walsh, a world-leading researcher in the field of artificial intelligence, explores the ethical considerations and unexpected consequences AI poses. Can AI be racist? Can robots have rights? What happens if a self-driving car kills someone? What limitations should we put on the use of facial recognition? Machines Behaving Badly is a thought-provoking look at the increasing human reliance on robotics and the decisions that need to be made now to ensure the future of AI iTrade Review''AI is more than the machine. It’s as much about us and our society that creates and, in turn, is changed by it. This is a thrilling and alarming vision that Machines Behaving Badly effortlessly shares through engaging stories and insights from a researcher at the forefront of this global transformation.’' -- Alan Duffy

Wiley-VCH Verlag GmbH Fundamentals of Inkjet Printing: The Science of
Book SynopsisFrom droplet formation to final applications, this practical book presents the subject in a comprehensive and clear form, using only content derived from the latest published results.Starting at the very beginning, the topic of fluid mechanics is explained, allowing for a suitable regime for printing inks to subsequently be selected. There then follows a discussion on different print-head types and how to form droplets, covering the behavior of droplets in flight and upon impact with the substrate, as well as the droplet's wetting and drying behavior at the substrate. Commonly observed effects, such as the coffee ring effect, are included as well as printing in the third dimension. The book concludes with a look at what the future holds. As a unique feature, worked examples both at the practical and simulation level, as well as case studies are included. As a result, students and engineers in R&D will come to fully understand the complete process of inkjet printing.Table of ContentsList of Contributors Preface xxi 1 Introductory Remarks 1 Ian M.

Crecy Publishing Boulton Paul 1917-1961
Book SynopsisA prolific sub-contractor building airframes during the First World War, Boulton & Paul entered thefield of design and manufacture in 1917 with the formation of an Aeronautical and Research Divisionunder John Dudley North. Never destined to be one of the big players, they produced a relativelymodest output of prototype aircraft and then in 1937 a series of bombers and a small batch ofcivilian two seaters. The relatively unsuccessful Defiant was their best known aircraft.However, hidden from public view was a prolific output of proposals, trials and inventions. Frombiplane fighters through the novel turret fighters and into the supersonic age with VTOL lift-fan jets,Boulton Paul were always at the forefront of development.Based upon over 60 years of research, this book recounts many of these radical and innovativeprojects using development layouts, final schemes, drawings and photographs of mock-ups, modelsand prototype airframes. Many projects are recreated in CAD and other drawings by the authorpreviously an apprentice and a technical engineer with the company and archivist of the BoultonPaul Association.This book sheds much new light on the activities of a hitherto often overlooked company which wasin many respects at the forefront of aeronautical innovation in Britain for several decades.

Bloomsbury Publishing PLC Infantry Antiaircraft Missiles
Book SynopsisNoted authority Steven J. Zaloga charts the development, combat use, and influence of man-portable air defense systems, from the late 1960s to the present day.The first attempts at developing a man-portable air defense system (MANPADS) based around a guided missile began in the mid-1950s, as a response to the increased speed and maneuverability of jet aircraft. This book charts the technological evolution of the MANPADS and explores their combat usage and the lessons from these encounters. Besides detailing the missiles, it also surveys the various methods developed as countermeasures to the MANPADS threat.The first generation of MANPADS, such as the US Army's Redeye and the Soviet Strela-2 (SA-7 Grail), saw combat use in the Vietnam War in 1972 and the Yom Kippur War of 1973. The next generation of infrared-guided MANPADS, such as the US Stinger and Soviet Igla, came to prominence following the Soviet invasion of Afghanistan in 1979. Since the 1970s, MANPADS have been used in iTable of Contents[provisional] Introduction Development Use Impact Conclusion Bibliography Index

Chelsea Green Publishing Co The Small-Scale Poultry Flock, Revised Edition:
Book SynopsisThe first edition of The Small-Scale Poultry Flock helped thousands of small-scale farmers and smallholders adopt a practical model for working with chickens and other domestic fowl based on natural systems. In this expanded and thoroughly revised edition, readers will find plenty of all-new material. Author Harvey Ussery introduces readers to his new favorite breed of chicken, Icelandics; describes how he manages his breeding flock using a clan mating system; presents detailed information on the use of trapnests and record-keeping spreadsheets for evaluating breeding hen performance; and provides step-by-step instructions for construction of an ingeniously designed mobile poultry shelter. Readers will also find fully updated information and tips on all aspects of flock management, including: growing (and sourcing) feed on a small scale cultivating earthworms and grubs as high-protein poultry feed brooding (and breeding) at home implementing manure management using electric net fencing for ranging flocks using poultry as insect and weed managers in the garden and orchard enlisting your chickens as garden tillers and compost-makers protecting the flock from predators keeping the flock healthy working with mother hens In The Small-Scale Poultry Flock, Revised Edition Ussery presents a sustainable and ecologically friendly model that can be adapted to a variety of scales. His advice and examples throughout the book will prove invaluable for beginner farmers, growers looking to incorporate poultry into their programme and experienced farmers looking to create a truly sustainable system.Trade Review“Ussery provides an encyclopedia of chicken and other fowl care, encompassing everything from anatomy and species selection to feeding, breeding, and selling in the local market. . . . Altogether, there’s no better introductory reference on the joy of home-raising chickens.” —Booklist“Written by a self-described ‘old hick with chickenshit on his boots,’ The Small-Scale Poultry Flock is a welcoming and decisive guide to the poultry-keeping experience. Harvey Ussery’s natural approach is that of a partnership with his flock, in what he terms ‘an integrated food independence enterprise.’ The author shares straightforward, encouraging information written from the viewpoint of someone who desires to share the knowledge that has come out of three decades of hard-won experience. Anyone considering a natural approach to producing eggs and meat will cherish this must-have reference, enjoyable to sit down and read cover-to-cover, but also perfect for answers on the go.” —Foreword Review“As usual, Harvey never ceases to amaze with his in-depth knowledge of poultry keeping. I love that, as knowledgeable as he is, he still constantly searches for new ‘tweaks’ to improve his farm efforts and the quality of life for his birds. He writes from that direct experience and it certainly shows in this wonderful go-to book for any aspiring poultry keeper. So many people claim to be chicken husbandry experts, but Harvey, he’s the real deal.” —Jeannette Beranger, senior program manager, The Livestock Conservancy“Harvey Ussery has spent a lifetime developing and showcasing a truly viable poultry model that is ultimately carbon-sequestering, hygienic, neighbor-friendly, and food-secure. . . . This book is about a call to heritage, to the wisest of wise traditions in food security and relationships. Harvey brings the latest tools and practices within the grasp of any aspiring flockster. It is this functional spirit that makes this book a classic in the small-scale poultry rearing genre.” —Joel Salatin, Polyface, Inc.“Amid the new and urgent focus on holistic, inputs-free food production married to ecologically robust land management, this expanded edition of Harvey Ussery’s classic guide to all things chicken should have a place on every small farm or homestead bookshelf. Dedicated to the conviction that what is best for the animal and the land will always be best for the farmer, Ussery points the novice ‘flockster’ toward best practice, while he inspires the long-time poultry keeper with a deeper commitment to ecological cooperation.” —Shawn and Beth Dougherty, authors of The Independent Farmstead“Here’s the ultimate book for those who want to know everything there is to know about raising poultry. And every detail is backed up by the author’s own (often entertaining) experiences. I could not find—in this encyclopedic array of chicken knowhow—one detail that I could quibble with.” —Gene Logsdon, author of Letter to a Young Farmer and Holy Shit“The Small-Scale Poultry Flock is the perfect book for all chicken keepers, from the folks just starting out to the most experienced. It covers everything from the history of the species and coop designs to feeding, breeding, keeping predators at bay, processing meat, and much more. Harvey’s writing style is easy going and feels like an old friend giving you sound advice. This is a comprehensive resource to keep on your bookshelf for many years to come.” —Jessi Bloom, author of Free-Range Chicken Gardens; coauthor of Practical Permaculture“It is refreshing and inspiring to read a book on chickens that has original content and creative techniques. This can only come from personal insights and hands-on experience. Harvey Ussery eloquently describes how to keep and employ a family flock of chickens. “Chickens have migrated with humans for over 3,000 years all over the planet. It’s time to bring them back home. Let them work in our communities and production gardens where they can feed not only themselves and humans, but also the soul and soil of Nature, enabling an abundant ecology. Food security with a consistent supply chain can be as close as your own backyard. Just read and use the practices described in The Small-Scale Poultry Flock. You will not be disappointed. High fives to Harvey!” —Pat Foreman, author of City Chicks; founder, The Gossamer Foundation“This book is packed with practical advice on raising poultry by someone who has not only done it all but has learned from his broad experience and knows how to communicate that wisdom clearly and in a lively, readable style. Harvey Ussery has written one of the most comprehensive guides out there, but what places it above the rest of the crowd is that he shows you how to work with nature rather than against it in ways that will minimize work while ensuring the health and happiness of the flock. Whether you're a beginner or an old-time poultry farmer, you shouldn’t go any further without this excellent manual.” —Toby Hemenway, author of Gaia’s Garden and The Permaculture City“The Small-Scale Poultry Flock is about establishing a free-range poultry flock fully integrated into a healthy homestead ecosystem. Based upon the author’s decades of hands-on experience with many breeds and species, it covers all the basics about raising poultry, and fills some important gaps not usually covered well enough elsewhere, including chicken behavior, poultry breeding, raising chicks with broody hens, managing free-ranging, dealing with predators, using electric net fencing, feeding poultry with home-grown feeds, and integrating the poultry with soil mineral balance, gardens, lawns and pastures, orchards, worm bins, and soldier fly (larvae) production. If you want to raise chickens and can afford just one book, I recommend this one.” —Carol Deppe, author of The Resilient Gardener“Ussery’s outstanding book is certain to withstand the test of time both for its encyclopedic and practical information, and for its acknowledgment that the future of our culture and our food security is in the hands of the small farmer and backyard producer. If you are starting out with your first flock, this is your book. And when you’ve been keeping poultry for 30+ years, this will still be your best book.” —Shannon Hayes, author of The Grassfed Gourmet Cookbook and Radical Homemakers“Anyone interested in practical, experienced, insightful information about how to select, breed, care for, manage, feed, protect, process, eat or market small-scale poultry flocks for their own eating pleasure or selling to others—and have FUN—should read this book.” —Frederick Kirschenmann, distinguished fellow, Leopold Center for Sustainable Agriculture; author of Cultivating an Ecological Conscience“There is a revolution going on, and it is the popular return of keeping poultry to provide food for our home tables. Ussery’s The Small-Scale Poultry Flock helps lead the way by integrating the small flock with its natural environment, the homestead, or small farm. Nowhere else will you find such valuable information on putting poultry to work in the garden, producing much of their feed, and producing healthful food for ourselves.” —Don Schrider, author of the American Livestock Breeds Conservancy’s Chicken Assessment for Improving Productivity and Storey’s Guide to Raising Turkeys "The Small-Scale Poultry Flock is an indispensable guide for homesteaders or market growers interested in doing it right. . . .[And] the revised edition packs in even more information than the original.” —Hobby Farms

Pen & Sword Books Ltd An Encyclopaedia of World Bridges
Book SynopsisBridges are one of the most important artefacts constructed by man, the structures having had an incalculable effect on the development of trade and civilisation throughout the world. Their construction has led to continuing advances in civil engineering technology, leading to bigger spans and the use of new materials. Their failures, too, whether from an inadequate understanding of engineering principles or as a result of natural catastrophes or warfare, have often caused immense hardship as a result of lost lives or broken communications. In this book, a sister publication to his earlier An Encyclopaedia of British Bridges (Pen & Sword 2019), David McFetrich gives brief descriptions of some 1200 bridges from more than 170 countries around the world. They represent a wide range of different types of structure (such as beam, cantilever, stayed and suspension bridges). Although some of the pictures are of extremely well-known structures, many are not so widely recognisable and a separate section of the book includes more than seventy lists of bridges with distinctly unusual characteristics in their design, usage and history.

Chelsea Green Publishing Co Our Wild Farming Life: Adventures on a Scottish
Book Synopsis[F]or anyone who has ever sat in a city office dreaming of owning a smallholding one day and living off the land, this book will inspire them to take the plunge. Rated 5 stars by The Telegraph I raced through this beautiful story with mounting awe and excitement. What Lynn and Sandra have achieved on their croft in Scotland is a miracle of rebirth on land Isabella Tree, author of Wilding The inspiring story of two courageous women who took the leap and embraced a whole new way of life. Kate Humble, author of Home Cooked As seen on the BBC’s This Farming Life Our Wild Farming Life is what happens when you follow your dreams of living on the land; a story of how two people became farmers – and how they learned to make a living from it, their way. Lynn and Sandra left their friends, family and jobs in England to travel north to Scotland to find a small piece of land they could call their own. They had no money, no plan and no experience in farming. They had in mind keeping a few chickens, a kitchen garden and renting out some camping space, but instead, they fell in love with Lynbreck Croft – 150 acres of wild Scottish Highlands filled with opportunity and beauty, shrouded by the Cairngorms mountains. This is the inspirational true story of Lynbreck Croft – a regenerative Scottish croft rooted in local food and community – and the dreams of two women in search of a new, wilder existence. In Our Wild Farming Life, Lynn and Sandra recount their experiences as they rebuild their new home and work out what kind of farmers they want to be. They learn how to work with Highland cattle, become part of the crofting community and begin to truly understand how they can farm in harmony with nature to produce wonderful food for themselves and the people around them. Through efforts like these, Lynn and Sandra have been able to combine regenerative farming practices with old crofting traditions to keep their own personal values intact.Trade Review‘I raced through this beautiful story with mounting awe and excitement. What Lynn and Sandra have achieved on their croft in Scotland is a miracle of rebirth on land that most would have considered beyond hope. Their success is testament to the wisdom of working with nature rather than battling against it and their pragmatism, honesty and openness to new and old ideas shines through on every page. I hope it inspires legions of new farmers.’—Isabella Tree, author of Wilding‘A ripping good account of the guts, luck and perseverance it takes to create a productive and healthy farm or croft that jumps the rails of our conventional industrial agriculture.’—Nick Offerman‘Full of refreshing honesty and a burning passion to reconnect food, communities and nature, what Lynn and Sandra have achieved is nothing short of incredible. These two are the real deal; humble pioneers during a critical time working selflessly to empower others. Lynbreck Croft is the embodiment of how humans should approach food production, and this book serves as an invaluable resource for anybody who has an interest in a regenerative future.’—Huw Richards, author of The Vegetable Grower’s Handbook‘The inspiring story of two courageous women who took the leap and embraced a whole new way of life. Lynn and Sandra, I salute you!’—Kate Humble, broadcaster and author of Home Cooked‘This is a story that needed to be told. I defy anyone to be in the presence of Lynn and Sandra for ten minutes and not come away inspired and with a smile. Arriving in the Highlands with a dream and very little else apart from determination, enthusiasm, passion, warmth and humility, they were not afraid to learn from mistakes and to seek help and advice. ‘The Highlands can be a welcoming place, but you have to earn it. Folk here won’t beat a path to your door unless you leave it wide open. And they did it. Neighbours embraced their dream and wanted to make it happen. To be a part of it. The gift of a cow. The gift of fuel. The gift of thousands of years of experience, knowledge and a love for the land.’—Euan McIlwraith, BBC TV and Radio presenter‘Many of us dream of going “back” to the land. Lynn Cassells and Sandra Baer have made it happen. In this inspirational, honest and quietly revelatory book they show how farming is not a lifestyle fantasy but a way of living, working and eating that is in partnership – with the land, the community, animals and each other. This is not a step back but the key to all our futures.’—Patrick Barkham, author of Wild Child "Their work on the croft is a true community endeavor....Our Wild Farming Life is a warm yet realistic chronicle of the world of the small-time farmer, sharing a vision of how we humans can feed ourselves sustainably and ethically while living in harmony with the natural world."—Booklist

The University of Chicago Press The Eyes of the World Mining the Digital Age in
Book SynopsisTrade Review"The Eyes of the World is a groundbreaking, brilliantly written book about Congo’s place in the global economy. Smith places artisanal miners of coltan at the center of his study. Contrary to most popular views of the Congolese as victims of global corporations and brutal state authorities, miners recognize their value as experienced workers who often can protect their interests. . . . Smith deftly weaves insights drawn from an array of anthropological theory with gripping, moving case studies of individual miners and mining sites. . . . Strikingly, Smith shows how Western efforts to crack down on 'blood diamonds' end up, in actuality, to be a tool to weaken the leverage of artisanal miners and allow wily state authorities to cash in on their ability to selectively enforce their will on Congolese workers. This book should be required reading for anyone who wants to understand the Democratic Republic of Congo today." * Choice *"Chock-full of fascinating details on the people and communities that have lived off mining in the chaos of the wars in Congo." * Foreign Affairs *"Beautiful and evocative. . . . Smith produces one of the richest and most thought-provoking ethnographies I have read in a very long time. The Eyes of the World is likely to become an anthropological classic." * Reviews in Anthropology *“Blood minerals: a global cause ‘intended to do one thing, but under the surface, invisible to many, . . . doing something else.’ Smith offers a whirlwind of research on the varied actors who extract coltan—often in the ruins of colonial concessions—making it available to international markets. The Eyes of the World skillfully cuts through metropolitan stereotypes, drawing readers instead into the astounding vortex of the mines.” * Anna Tsing, coeditor of Feral Atlas: The More-than-Human Anthropocene *“A riveting, wonderful potpourri of story, theory, and history. The Eyes of the World hugs closely to people’s lives, words, and theories, vividly unpacking multiple dimensions of movement in the mining of those digital minerals that end up in global devices. One of the most brilliant, important, and utterly teachable ethnographies to appear on Congo in a long time.” * Nancy Rose Hunt, author of A Nervous State: Violence, Reveries, and Remedies in Colonial Congo *“Smith gives us a rare glimpse into the complex dynamics of otherwise largely invisible local worlds that do nonetheless matter on a global scale. A great observer and talented narrator, he convincingly argues how, in the vortex of these Congolese mining worlds, destructive forms of extra-statecraft undid existing socio-cultural assemblages while generating the basis for new transformative orders.” * Filip De Boeck, author of Suturing the City: Living Together in Congo’s Urban Worlds *"Smith’s book is bound to become a classic in the anthropology of mining and the conflict minerals literature. . . . This book is an absolute joy to read and sets the bar very high for future researchers working on the issue of conflict minerals. This is mining anthropology at its very best." * The Journal of Development Studies *Table of ContentsPart One: Orientations Prologue: An Introduction to the Personal, Methodological, and Spatiotemporal Scales of the Project 1.

Book SynopsisOne of the great classics of Scottish history, The Drove Roads of Scotland interweaves folklore, social comment and economic history in a fascinating account of Scotland’s droving trade and the routes by which cattle and sheep were brought from every corner of the land to markets in central Scotland. In pastoral Scotland, the breeding and movement of livestock were fundamental to the lives of the people. The story of the drove roads takes the reader on an engrossing tour of Scottish history, from the lawless cattle driving by reivers in the sixteenth and seventeenth centuries to the legitimate movement of stock which developed after the Union of the Crowns, by which time the large-scale movement of stock to established markets had become an important part of Scotland’s economy, and a vital aspect of commercial life in the Empire.Trade Review'a great classic of Scottish history - a masterpiece' * Highland News *'Comprehensive and continuously engrossing' * The Scotsman *
