The highest peak in the eastern United States, Mount Mitchell towers 6,684 feet over its home in Yancey County, North Carolina. It has borne silent witness to great scientific and personal achievements, tragic loss of life, heated debates, and a host of controversies both great and small. Once considered forbidding and remote, it claimed the life of its namesake, Elisha Mitchell, when he fell to his death in an attempt to firmly establish the mountain's height. In the early 1900s, entrepreneurs constructed a railroad, opening its old-growth forests to massive deforestation. This devastation stirred some of the earliest notions of environmentalism that led to Mount Mitchell's establishment as North Carolina's first state park. Today, it is a playground for tourists from around the world, offering some of the best hiking and views in the nation. Mount Mitchell showcases the rich history of the mountain along with the events and colorful characters that have shaped its story.

Magnetic Components Design and Applications is intended primarily for the circuit designer and the power processing systems designer who have found that in order to be more effective they must learn not only to use, but to design their own magnetic components. It will also be useful to the trans former engineer, by showing how to develop high-performance designs quickly and easily by employing optimization criteria. This book is a design manual, a how-to-build-it manual, and a survey of some common and state-of-the-art practices in magnetic component design and high voltage insulation. It contains the data necessary to design power transformers on a gradient scale from 60 Hz to several hundred kilohertz, conventional and air-core current transformers, power reactors, saturable transformers and saturable reactors, and air core and conventional pulse transformers. Further, it con tains essential information about dielectric materials and fabrication meth ods, basic heat transfer technology, and electric field gradient control for high voltage applications. Mathematical methods of optimization are developed, and results are given in a number of areas, particularly in the area of maximizing power den sity in power transformers and the maximization of stored energy per unit volume for power reactors. For various reasons, each chapter is written from a different starting level.

Presents for the first time detailed data on the role played by multinationals in the industrial sectors of the OECD economies.

Bretherick's Handbook of Reactive Chemical Hazards, Fourth Edition, has been prepared and revised to give access to a wide and up-to-date selection of documented information to research students, practicing chemists, safety officers, and others concerned with the safe handling and use of reactive chemicals. This will allow ready assessment of the likely potential for reaction hazards which may be associated with an existing or proposed chemical compound or reaction system. A secondary, longer-term purpose is to present the information in a way which will, as far as possible, bring out the causes of, and interrelationships between, apparently disconnected facts and incidents. This handbook includes all information which had become available to the author by April 1989 on the reactivity hazards of individual elements or compounds, either alone or in combination. It begins with an introductory chapter that provides an overview of the complex subject of reactive chemical hazards, drawing attention to the underlying principles and to some practical aspects of minimizing such hazards. This is followed by two sections: Section 1 provides detailed information on the hazardous properties of individual chemicals, either alone or in combination with other compounds; the entries in Section 2 are of two distinct types. The first type of entry gives general information on the hazardous behavior of some recognizably discrete classes or groups of the 4,600 or so individual compounds for which details are given in Section 1. The second type of entry concerns reactive hazard topics, techniques, or incidents which have a common theme or pattern of behavior involving compounds of several different groups, so that no common structural feature exists for the compounds involved.
