Book SynopsisRoaming Wild details the unconventional and pioneering lives of Anna and Peter Roberts, a British couple who were instrumental in making the animal welfare movement a respectable, highly-impactful and worldwide organisation. This book explores the paths that led Anna and Peter to found and steward what is now the world's largest and most successful animal welfare charity from a backroom of their own home, with few funds, and at a time when caring for animals and our planet was seen as 'crankish' and 'sentimental'. This is the story of their family, their era, influence, their rebellion and prophetic ideas and the development of Compassion in World Farming. It spans the period from the early 1920s when they were born, throughout the decades of their childhoods and World War II, to their highly romantic meeting and marriage in the 1950s, and then the next years of their lives as dairy and chicken farmers in rural Hampshire. This 'ordinary' part of their story preceded their move to change everything by making the 'extraordinary' decision during the tumultuous 1960s, of risking their livelihood, going vegetarian (as animal farmers), and losing the approval of their peers, to found their compassion-driven campaign. This personal transformation was at a time when the British countryside was also transforming, irrevocably and for the worse, when intensive, polluting farms were just taking root, the cruel battery and broiler system had recently been developed, and the countryside's biodiversity was being destroyed with the implementation of monoculture and the profligate spraying of lethal biocides, such as DDT. The Roberts were at first rejected by the popular animal charities of the day; believing that the public cared only about companion animals or those in circuses, rather than those animals who suffer the most at human hands - those in the food chain - and so the Roberts family went out alone and set up CIWF in the face of much public derision. Then followed the highs and lows of campaign life, a court battle with an order of veal-farming Catholic monks, famine campaigns in Ethiopia, work alongside comedian Spike Milligan, model Celia Hammond and philosopher Peter Singer, challenging EU legislation, and battles with agricultural and chemical giant Monsanto. Corporate giants like McDonald's were influenced to go free-range, even the British Royal family was challenged to go free-range, and animals were put on the agenda of every major political party in the 1970s and much more. The story interweaves the personal with the political and documents the highs and lows of family life, the judgement faced when they chose to raise their three daughters as vegetarians in the 1960s, their myriad spiritual quests, including the couple's time spent in the Indian ashram of Sathya Sai Baba, their rewilding of the land near their family home, and the story of their fifty-year love. This is a tale of an 'ordinary couple with an extraordinary vision'.

Book SynopsisMicro-hydro is a useful way of providing power to houses, workshops or villages that need an independent supply. For many remote areas beyond the reach of a national grid, micro-hydro is the only economic option. Where flow is limited, but high heads are available, the Pelton wheel is one of the most useful turbines. The Micro-hydro Pelton Turbine Manual is written to enable the reader to design and manufacture Pelton turbines with capacities from a few hundred Watts to around 100kw, though much of the information is relevant for larger units too. Aimed at readers with a general engineering workshop background, the emphasis is on simple technology, so that the turbines can be made in small workshops with basic engineering facilities. More advanced processes are discussed for those with access to better manufacturing facilities. As well as detailing all the important aspects of design, the book covers basic theory, turbine selection, manufacture, installation, testing and problem-solving. The manual is well illustrated and contains a comprehensive appendices, containing manufacturing reference information and the derivation of equations used. Jeremy Thake, a mechanical design engineer, has worked for the appropriate technology organization, DCS, in Nepal for six years in micro-hydro systems. He currently works for the renewable energy consultancy, IT Power.

Book SynopsisThe message of Sustainable Livelihoods and Rural Development is clear: livelihoods approaches are an essential lens on questions of rural development, but these need to be situated in a better understanding of political economy. The book looks at the role of social institutions and the politics of policy, as well as issues of identity, gender and generation. The relationships between sustainability and livelihoods are examined, and the book situates livelihoods analysis within a wider political economy of environmental and agrarian change. Four dimensions of a new politics of livelihoods are suggested: a politics of interests, individuals, knowledge and ecology. Together, these suggest new ways of conceptualizing rural and agrarian issues, with profound implications for both thinking and action.

Book SynopsisHowever well equipped the workshop may be there seems to be an incessant need to make up special gadgets of one sort or another. These may range from mutilating a clothes peg to act as a 'third hand' up to major modifications to an existing machine tool. The making of such devices can be fun (indeed, some may appear to do nothing else!) but nevertheless the time taken up in 'devising the device' can often delay the completion of an important project. Shared experience is a most potent tool in reducing such delays, and can, moreover, often provide solutions to problems hitherto believed to be intractable. Tubal Cain has enjoyed more than sixty years' experience in designing and building engines and machines (in both full size and model dimensions) and over this time has made many ancillary devices. In this book he shares 52 of them with you. A number of these had been published in magazines from time to time and some were assembled in volume form about thirty years ago. The opportunity was later taken not only to reprint that book but to revise some of the entries to take advantage of user experience, to add new material and to introduce it into the popular Workshop Practice Series.Table of ContentsFive Clamp and Vice Projects. Ten Jigs and Fixtures. Twenty-five Projects Round and About the Lathe. Thirteen Miscellaneous Projects.

Book SynopsisThis book describes the construction of two different clock projects - an eight day regulator clock and a month going regulator clock - and features full-page fully-dimensionalised working drawings supported by detailed photographs. It also includes instructions and plans for constructing glazed wood cases for each project. It is intended for model engineering hobbyists with basic facilities to enable them to venture into the field of horology by building their own precision clocks which can become treasured family heirlooms. The term 'regulator' simply describes a precision clock. Every clockmaker and repairer needs such an instrument to use in regulating his repair and new work. The typical English regulator, as described in the first section, beats at one second intervals and will run for eight days between winding. The second project is a month going regulator clock, an equally high precision type which will run for a whole month between winding. This book is based on a popular series of popular articles originally published over many years in Model Engineer magazine.Trade ReviewThe publisher has built a very successful niche in special interest books of a technical and engineering nature. This is a worthy addition to the list. The author has described the design and construction of an 8 day regulator clock that requires only a modest selection of engineering tools and which could be built using components made to order by an engineering company. The result is a fine clock with an open dial that provides a view of most of the clock works, mounted in a wooden case with three sides in glass. As a clock, it will provide good time keeping. As an engineering project it will build into a satisfying and practical item that requires only wall space. As an object, it makes a good taking point. The descriptive text is well written and provides a very easy to follow guide to building the clock. The text is accompanied by very clear engineering drawings that provide all of the detail necessary to complete the components and assemble the clock - firetrench.com.Table of ContentsCONTENTS.

Book SynopsisIn recent years there has been an explosion of interest in organic and biodynamic produce. Although once marginal and 'alternative', escalating concerns about the environment, health, food quality and animal welfare have brought organics into mainstream consciousness. Biodynamics, a unique development of the organic approach, does not narrowly focus on agricultural techniques. It was conceived as a new way of thinking about farming, nutrition and the world of nature, allowing for a revitalized relationship with the living soil, the elemental world and the cosmos. Originating from a series of eight lectures given by Dr Rudolf Steiner in 1924, biodynamics broadens the outlook of agriculture and the science behind it, leading to a holistic perspective that incorporates astronomical rhythms and unique preparations for plants and earth. The author describes the foundations on which not only biodynamics but also the wider organic movement is based. He builds bridges between mainstream science and Steiner's insights, making it easier for the wider organic and ecological movement to approach biodynamic concepts and practise. This book has much to offer to the beginner as well as to those already involved with biodynamics. Its broad range of topics - including the ecology of the farm organism, food quality and nutrition, community supported agriculture, planetary influences, seed quality, and the vitality of water - contribute to a deeper understanding of the subject. The author is also concerned to promote innovation so that biodynamics moves with the times. An appendix includes details for contacting various elements of the biodynamic world.

Book SynopsisIn Logomotive Ian Logan's photographs are assembled into chapters and picture essays recalling the great days of lines such as the Santa Fe, the Union Pacific, and the Kansas City Southern. Some of his journeys are presented as travelogues in which he meets the Fat Controller, gets to sound the horn, and wanders into freight yards to see the last generation of streamline locomotives rusting amid the weeds. Animal motifs, Native American allusions, advertising slogans, names of famous trains such as the Super Chief and the Wabash Cannonball provide the subject matter for other picture features.Trade ReviewIn these times, the commercial design agenda is generally set by things like automobiles, sneakers, and financial institutions. We see their logos, typographic trends, and color schemes everywhere—on billboards, atop stadiums, beaming at us from our flatscreens and smartphones. Decades ago, though, the public design space was largely the province of railroads, as shown in Logomotive: Railroad Graphics and the American Dream, a beautifully produced compendium of railroad design from Sheldrake Press, a London-based publisher. The authors are Ian Logan, a noted practitioner on the British and European design scene; and Jonathan Glancey, a veteran writer and correspondent who covers design and architecture. Award-winning British architect Norman Foster offers an eloquent and insightful Foreword. The authors bring a fresh and utterly British sense of surprise to a subject that, for readers of this magazine, is likely quite familiar. I got a kick out of Logan’s story about his first trip to the United States, in 1968, and his encounter with a famous name on the side of a boxcar. “I couldn’t believe what I was seeing: the train was emblazoned with the name Rock Island. My uncle was the singer and songwriter Ewan MacColl, and I was brought up listening to folk, skiffle, and blues, so of course I knew Ronnie Donegan’s recording of the ‘Rock Island Line,’ but I hadn’t worked out that the Rock Island was a real, operational railroad.” The rest of the book chronicles similar revelations. Much of Logomotive is dedicated to exploring and showcasing the company logos and heralds that have enlivened the railroad scene since the late nineteenth century. You will see multiple iterations of all the classics—the Pennsylvania keystone, Santa Fe’s Warbonnet, MoPac’s buzzsaw, Seaboard’s red heart, B&O’s capitol silhouette—plus several obscure ones, accompanied by the authors’ sharp typographical and design analysis. One of the strengths of the book are the myriad visual contexts of the logos: on timetables and travel posters, along the flanks of diesels and freight cars and early streamliners, embedded into the walls and lintels of great stations, imprinted on matchbooks and ashtrays. It’s refreshing that not everything is presented in a pristine state. There is a poignancy to a weathered Western Pacific Feather River herald, riveted to the side of a tugboat funnel; or to an SP “Sunset” logo, struggling to be seen through the rust of an old freight car. As familiar as the subject might be, you can learn a lot from this book. I was fascinated by its take on designer Herbert Matter’s creation of the famous McGinnis-era New Haven logo, as well as Allan Fleming’s evolution of Canadian National’s superbly modernistic “CN,” first envisioned on a paper napkin. You’ll see the way New York Central’s oval transitioned from its early elegant serif font to the sans-serif sterility of the cigar band, or how Great Northern’s Rocky the mountain goat was updated. There were surprises, too, at least for me. I had never realized that the Cotton Belt logo of the 1880s derived from a cross-section of a cotton gin, and I was surprised to learn that design superstar Milton Glaser was responsible for Genesee & Wyoming’s versatile black-orange-yellow brand. The publisher has served its subject well, with a first-class horizontal treatment that includes sharp color printing, heavy paper, and a durable imprinted cover. Although the rather brief narrative is aimed at a general audience—some of the Brits’ observations are amusing, and a glossary at the end is as basic as can be—the book serves as an authoritative overview of the high tide of railroad design, written by professionals who really know their business. -- Kevin P.

Book SynopsisRadar cross section (RCS) is a comparison of two radar signal strengths. One is the strength of the radar beam sweeping over a target, the other is the strength of the reflected echo sensed by the receiver. This book shows how the RCS gauge can be predicted for theoretical objects and how it can be measured for real targets. Predicting RCS is not easy, even for simple objects like spheres or cylinders, but this book explains the two exact forms of theory so well that even a novice will understand enough to make close predictions. Weapons systems developers are keenly interested in reducing the RCS of their platforms. The two most practical ways to reduce RCS are shaping and absorption. This book explains both in great detail, especially in the design, evaluation, and selection of radar absorbers. There is also great detail on the design and employment of indoor and outdoor test ranges for scale models or for full-scale targets (such as aircraft). In essence, this book covers everything you need to know about RCS, from what it is, how to predict and measure, and how to test targets (indoors and out), and how to beat it.Table of Contents Chapter 1: Introduction Chapter 2: Radar Fundamentals Chapter 3: Physics and Overview of Electromagnetic Scattering Chapter 4: Exact Prediction Techniques Chapter 5: High-Frequency RCS Prediction Techniques Chapter 6: Phenomenological Examples of Radar Cross Section Chapter 7: Radar Cross Section Reduction Chapter 8: Radar Absorbing Materials Chapter 9: Radar Absorber Measurement Techniques Chapter 10: Antenna RCS and RCSR Chapter 11: RCS Measurement Requirements Chapter 12: Outdoor RCS Test Ranges Chapter 13: Indoor RCS Ranges Chapter 14: Hip-Pocket RCS Estimation, Data Presentation, and Reduction

Book SynopsisThis is the only English language book on bistatic radar. It starts with James Casper's fine chapter in the first edition of Skolnik's Radar Handbook (1970), capturing previously unpublished work before 1970. It then summarizes and codifies subsequent bistatic radar research and development, especially as catalogued in the special December 1986 IEE journal. It defines and resolves many issues and controversies plaguing bistatic radar, including predicted performance, monostatic equivalence, bistatic radar cross section and resolution, bistatic Doppler, hitchhiking, SAR, ECM/ECCM, and, most importantly, the utility of bistatic radars. The text provides a history of bistatic systems that points out to potential designers, the applications that have worked and the dead-ends not worth pursuing. The text reviews the basic concepts and definitions, and explains the mathematical development of relationships, such as geometry, Ovals of Cassini, dynamic range, isorange and isodoppler contours, target doppler, and clutter doppler spread.Table of Contents Chapter 1: Introduction and Overview Chapter 2: History Chapter 3: Coordinate Systems, Geometry, and Equations Chapter 4: Range Relationships Chapter 5: Location and Area Relationships Chapter 6: Doppler Relationships Chapter 7: Target Resolution Chapter 8: Target Cross Section Chapter 9: Clutter Chapter 10: Electronic Countermeasures and Counter-Countermeasures Chapter 11: Multistatic Radars Chapter 12: Special Concepts and Applications Chapter 13: Special Problems and Requirements Appendix A: Early Publications of Bistatic Radar Phenomenology Appendix B: Width of a Bistatic Range Cell Appendix C: Approximation to the Location Equation Appendix D: Area within a Maximum Range Oval of Cassini Appendix E: Relationships Between Parameters in Target Location and Clutter Doppler Spread Equations Appendix F: Orthogonal Conic Section Theorems

Book SynopsisPalladius wrote in the 5th century AD. His is the latest of Roman agricultural texts and perhaps for that reason was the treatise most widely distributed in the medieval world, being translated into Italian, Catalan and Middle English, among other languages. Later, Palladius fell into neglect as the Renaissance preferred more classical authors (Cato, Varro, Columella.

Book SynopsisBiodynamics is about respect for nature, sustainability and spiritual ecology - but most of all it is about flavoursome, nutritious and enjoyable food! This is a book rich in information, beautifully illustrated and packed with healthy yet tasty recipes. It is a movement that is supported by top chefs, expert viniculturists and numerous celebrities. Even Prince Charles has introduced its methods at his Gloucestershire farm. Yet biodynamic agriculture had humble beginnings, far from the glitz of expensive city restaurants. In 1924 a small group gathered to hear the philosopher and scientist Rudolf Steiner give a series of lectures. At a time when industrial farming and mass production were on the rise, Steiner spoke of the qualitative aspects of food, and outlined an agricultural method founded on a holistic perception of nature. Illustrated with hundreds of full-colour photographs, "The Biodynamic Food and Cookbook" explains the principles behind biodynamics, and places it in the context of food and cooking throughout the ages. Wendy Cook takes us on a journey through the four seasons, presenting over 150 delicious recipes based on years of working with biodynamic nutrition. She studies the ethics of food, the foundations of a balanced diet, and conjures up the colour and vibrancy of Mallorca which has contributed so much to her personal approach. There are supplementary sections on breads, sauces, salads, sweets, drinks and much more.Trade Review'Should be required reading for anyone who cares about good food.' - The Times 'In my experience, biodynamic food is of exceptional quality and taste - so I use it when I can. And it's good for my health!' - Antony Worrall Thompson I know from my own experience that eating biodynamically grown food in good company leaves a fine and lasting impression on the palette. This is because the biodynamic farming which is built upon sound organic principles aims to enhance the quality and vitality of our food. - Patrick Holden, Director, Soil Association
