This book proposes the tool change methods for the excessive tool wear in the construction rules of shield tunnel construction in China. From the perspective of shield tunneling, atmospheric pressure tool change, pressure opening and tool change, and other special techniques, the tool change technologies are proposed. It highlights a number of tool-changing techniques and research and development work, including pressure-changing tools, tool-changing tools in the tool-cylinder arm, and cutter-tooth cutter inter-change since the beginning of the construction of the Nanjing Yangtze River Tunnel.

Vaccines have saved more lives than any other single medical advance. Yet today only four companies make vaccines, and there is a growing crisis in vaccine availability. Why has this happened? This remarkable book recounts for the first time a devastating episode in 1955 at Cutter Laboratories in Berkeley, California, thathas led many pharmaceutical companies to abandon vaccine manufacture. Drawing on interviews with public health officials, pharmaceutical company executives, attorneys, Cutter employees, and victims of the vaccine, as well as on previously unavailable archives, Dr. Paul Offit offers a full account of the Cutter disaster. He describes the nation's relief when the polio vaccine was developed by Jonas Salk in 1955, the production of the vaccine at industrial facilities such as the one operated by Cutter, and the tragedy that occurred when 200,000 people were inadvertently injected with live virulent polio virus: 70,000 became ill, 200 were permanently paralyzed, and 10 died. Dr. Offit also explores how, as a consequence of the tragedy, one jury's verdict set in motion events that eventually suppressed the production of vaccines already licensed and deterred the development of new vaccines that hold the promise of preventing other fatal diseases.

Fishing vessels are popular as models. Especially the small cutters, as one can experience them up close on holiday in numerous harbours on the North Sea and Baltic Sea, but also on the Mediterranean, exert a great attraction on model ship builders. In this book, cutter enthusiasts Jürgen Behrendt and Stefan Schmischke provide the reader with the necessary information to build realistic and attractive models of small fishing vessels. Basic information (so that one understands what happens on board), constructional features and, above all, special functions and detailing are the topics. Building tips for various models, an overview of fishing cutter kits and a presentation of sources of supply for building and refining models round off the subject. Over 400 illustrations show models and originals and clarify building techniques and special detailing. Come with us on a fishing trip! From the content: • Why cutters? • Cutter in the original • Fishing methods • Ports, shipyards, experiences • Marking of fishing vessels in Germany • Implementation in the model • Behind the scenes • Market review – Kits briefly • Model specifications • Improvements to cutter models • Special functions • Detailing • Weathering • Variations in the model • Sources of supply

With a unique combination of ancient and contemporary wisdom from the Tibetan Buddhist tradition, The Diamond Cutter presents readers with empowering strategies for success in their work and personal lives. Geshe Michael Roach, one of the great teachers today of Tibetan Buddhism, has richly woven The Diamond Cutter in three layers. The first is a translation of selections from the Diamond Sutra itself, an ancient text comprised of conversations between the Buddha and his close disciple Subhuti. Considered a central work by Buddhists throughout the world, the Diamond Sutra has been the focus of much interpretation over the centuries. In the second layer, Geshe Michael quotes from some of the best commentaries of the Tibetan tradition. In the main text, the third layer, he uses both sutra and commentary as a jumping-off point for presenting his own teaching. Geshe Michael gives fresh insight into ancient wisdom by using examples from his own experience as one of the founders of the Andin International Diamond Corporation, which was started with capital of fifty thousand dollars and which today has annual sales in excess of one hundred million dollars. Much of the success of Andin has come from applying the business strategies presented in The Diamond Cutter. Geshe Michael's easy style and spiritual understanding make this work of timeless wisdom an invaluable source for those already familiar with, and those unfamiliar with, Tibetan Buddhism.

Those who've spent time with the elderly Amish woman realize the wisdom in her words. One could say Catherine's kitchen is her office. Baking cookies is her form of therapy. Christmas wreaths, nailed to the porch of the Amish home, attract the eye of photographer Claire Ryan. Knocking on the door, she plans on asking permission to take some photos and then be on her way. But once inside, sitting in the warmth of that home with paper angels on strings and pine boughs decorating the mantel, Claire relaxes, eventually telling Catherine why she's about given up on finding love and no longer bothers with Christmas. Soon they're in the kitchen getting ready to make cookies. When Catherine brings out a wooden box holding old tin cookie cutters, Claire notices one is missing. The cookie cutter is found weeks later -- and it has nothing to do with making cookies.
