This book provides a comprehensive overview of magnetic levitation (Maglev) technologies, from fundamental principles through to the state-of-the-art, and describes applications both realised and under development. It includes a history of Maglev science and technology showing the various milestones in its advancement. The core concepts, operating principles and main challenges of Maglev applications attempted across various fields are introduced and discussed. The principle difficulties encountered when applying Maglev technology to different systems, namely air gap control and stabilization, are addressed in detail. The book describes how major advancements in linear motor and magnet technologies have enabled the development of the linear-motor-powered Maglev train, which has a high speed advantage over conventional wheeled trains and has the potential to reach speed levels achieved by aircraft. However, many expect that Maglev technology to be a green technology that is applied not only in rail transportation, but also in diverse other fields; to ensure clean transfer in LCD manufacturing, in ropeless high speed elevators, small capacity rail transportation, space vehicle launchers, missile testers, energy storage, and so on. These potential applications and their unique challenges and proposed technological solutions are introduced and discussed in depth. The book will provide readers from academia, research institutes and industry with insights on where and how to apply Maglev technology, and will serve as a guide to the realization of their Maglev applications.

From Peter Pan to Harry Potter, from David Copperfield to levitating toys, there is magic in conquering gravity. In this first-ever popular introduction to âeoemaglevâe âe" the use of magnetic forces to overcome gravity and frictionâe"James D. Livingston takes lay readers on a journey of discovery, from basic concepts to todayâe(tm)s most thrilling applications. The tour begins with examples of our historical fascination with levitation, both real and fake. At the next stop, Livingston introduces readers to the components of maglev: gravitational and magnetic forces in the universe, force fields, diamagnetism and stabilization, superdiamagnetism and supercurrents, maglev nanotechnology, and more. He explores the development of the superconductors that are making large-scale levitation devices possible, and the use of magnetic bearings in products ranging from implanted blood pumps to wind turbines, integrated circuit fabrication, and centrifuges to enrich uranium. In the last chapters, we arrive at the science behind maglev transportation systems, such as Chinese trains that travel 250 miles per hour without touching the tracks. Packed with fascinating anecdotes about the colorful personalities who have âeoefought friction by fighting gravity,âe the book maintains accuracy throughout while it entertains and informs technical and nontechnical readers alike. With so many new applications for magnetic levitation on the horizon, Rising Force is sure to retain its own magic for years to come.

Has the future a future? Are we bringing history to an end? Observing any one of several individual but critical trends suggests that, without rapid and positive action, history may have only a very short way to run. Whether it is the growth of world population, of greenhouse gas concentrations and the accelerating rate of climate change, the running down of oil and natural gas reserves, growing shortages of fresh water for agriculture, industry and domestic use, or the increasing difficulty in controlling epidemic diseases we are facing a mounting global crisis that will peak in less than a generation, around the year 2030. Taken together, these trends point to a potentially apocalyptic period, if not for the planet itself then certainly for human societies and for humankind. In this compelling book, and update to The 2030 Spike, Colin Mason explains in clear and irrefutable terms what is going on largely below the surface of our daily or weekly news bulletins. The picture he paints is stark, and yet it is not bleak. Being forewarned, we are forearmed, and he draws on his own extensive political experience to describe how much we can do as individuals, and above all collectively, not merely to avert crisis but to engineer thoroughgoing change that can usher in genuinely sustainable and valuable alternatives to the way we live now.

Cancer cell biology research in general, and anti-cancer drug development specifically, still relies on standard cell culture techniques that place the cells in an unnatural environment. As a consequence, growing tumor cells in plastic dishes places a selective pressure that substantially alters their original molecular and phenotypic properties.The emerging field of regenerative medicine has developed bioengineered tissue platforms that can better mimic the structure and cellular heterogeneity of in vivo tissue, and are suitable for tumor bioengineering research. Microengineering technologies have resulted in advanced methods for creating and culturing 3-D human tissue. By encapsulating the respective cell type or combining several cell types to form tissues, these model organs can be viable for longer periods of time and are cultured to develop functional properties similar to native tissues. This approach recapitulates the dynamic role of cell–cell, cell–ECM, and mechanical interactions inside the tumor. Further incorporation of cells representative of the tumor stroma, such as endothelial cells (EC) and tumor fibroblasts, can mimic the in vivo tumor microenvironment. Collectively, bioengineered tumors create an important resource for the in vitro study of tumor growth in 3D including tumor biomechanics and the effects of anti-cancer drugs on 3D tumor tissue. These technologies have the potential to overcome current limitations to genetic and histological tumor classification and development of personalized therapies.
