Drive models for steam engines and hot air engines
Many modellers – especially beginners – ask themselves when the first steam engine or hot-air engine model is finished and working: and now? After all, such machines were originally intended to do work and enable mechanical activities. Early on, the suppliers of toy steam engines therefore came up with the idea of producing drive models in which the engines could deliver their power in a meaningful way. But many of these suppliers no longer exist, many machines are only available in antiquarian form and the supply of finished drive models is limited – and besides, making your own is much more exciting anyway! This is also the opinion of Volker Koch, who describes in this book numerous ...
Steam-powered workshops as model
The use of steam engines to drive machine tools was the cornerstone of the first industrial revolution, and it was only the use of electric motors that made the complicated - and not entirely harmless - transmissions superfluous. No wonder, then, that model makers are also fascinated by such workshops with their complex mechanics. But how do you build such a workshop? Can you build it yourself? Or can commercially available components be used to create an attractive steam workshop? Volker Koch answers these questions and many more in his extensively illustrated book, which revives a fascinating piece of technical history. From the content: Driving machines, transmissions, operating models The "three-part machine system” Driving machines for model workshops Transmissions for model workshops Operating models for model workshops Drive by a simple model locomobile Robust self-made steam engine A simple hammer mill with steam drive Model workshop with Märklin components A simple Mamod layout Self-made operating models

Future Cities
Future Cities For the first time in human history, more than 50% of the world's population lives in urban regions. Cities are the largest, most complex, and most dynamic man-made systems. They are vibrant centers of cultural life and engines that drive the global economy. Contemporary cities are environmentally, socially, and economically unsustainable. The quality of urban life is threatened by such factors as pollution, rising temperatures, limited resources, congestion, social inequalities, aging of large sectors of the world population, poverty, informality, crime, and economic imbalances. The overall planning of future cities is a challenge that can only be faced by interdisciplinary te...
Disease and Democracy
Disease and Democracy is the first comparative analysis of how Western democratic nations have coped with AIDS. Peter Baldwin's exploration of divergent approaches to the epidemic in the United States and several European nations is a springboard for a wide-ranging and sophisticated historical analysis of public health practices and policies. In addition to his comprehensive presentation of information on approaches to AIDS, Baldwin's authoritative book provides a new perspective on our most enduring political dilemma: how to reconcile individual liberty with the safety of the community. Baldwin finds that Western democratic nations have adopted much more varied approaches to AIDS than is commonly recognized. He situates the range of responses to AIDS within the span of past attempts to control contagious disease and discovers the crucial role that history has played in developing these various approaches. Baldwin finds that the various tactics adopted to fight AIDS have sprung largely from those adopted against the classic epidemic diseases of the nineteenth century—especially cholera—and that they reflect the long institutional memories embodied in public health institutions.
Mangrove Dynamics and Management in North Brazil
Mangrove ecosystems are being increasingly threatened by human activities. Their biotic productivity supplies food and other resources to the human populations that inhabit or make use of them. This volume highlights the results of a ten-year German / Brazilian research project, called MADAM, in one of the largest continuous mangrove areas of the world, located in northern Brazil. Based on the analysis of the ecosystem dynamics, management strategies for the conservation and sustainable use of mangroves are presented and discussed. Beyond the scientific results, this book also provides guidelines for the development of international cooperation projects.

Global Design and Local Materialization
This book constitutes the refereed proceedings of the 15th International Conference on Computer-Aided Architectural Design Futures, CAAD Futures 2013, held in Shanghai, China, in July 2013. The 35 revised full papers presented were carefully reviewed and selected from 78 submissions. The papers are organized in topical sections on digital aids to design creativity, concepts, and strategies; digital fabrication and local materialization; human-computer interaction, user participation, and collaborative design; modeling and simulation; shape and form studies.
Food Co-ops in America
In recent years, American shoppers have become more conscious of their food choices and have increasingly turned to CSAs, farmers' markets, organic foods in supermarkets, and to joining and forming new food co-ops. In fact, food co-ops have been a viable food source, as well as a means of collective and democratic ownership, for nearly 180 years. In Food Co-ops in America, Anne Meis Knupfer examines the economic and democratic ideals of food cooperatives. She shows readers what the histories of food co-ops can tell us about our rights as consumers, how we can practice democracy and community, and how we might do business differently. In the first history of food co-ops in the United States, ...
