Leland Johnson and Daniel Schaffer begin their narrative in 1943 when the U.S. Army Corps of Engineers built ORNL in the hills of East Tennessee to produce plutonium for atomic weapons. After World War II, ORNL became a center for fundamental scientific research under the successive management of the Atomic Energy Commission, the Energy Research and Development Administration, and the Department of Energy.
Research on ferroelectricity and ferroelectric materials started in 1920 with the discovery by Valasek that the variation of spontaneous polarization in Rochelle salt with sign and magnitude of an applied electric field traced a complete and reproducible hysteresis loop. Activity in the field was sporadic until 1935, when Busch and co-workers announced the observation of similar behavior in potassium dihydrogen phosphate and related compounds. Progress thereafter continued at a modest level with the undertaking of some theoretical as well as further experimental studies. In 1944, von Hippel and co-workers discovered ferroelectricity in barium titanate. The technological importance of ceramic barium titanate and other perovskites led to an upsurge of interest, with many new ferroelectrics being identified in the following decade. By 1967, about 2000 papers on various aspects of ferroelectricity had been published. The bulk of this widely dispersed literature was concerned with the experimental measurement of dielectric, crystallographic, thermal, electromechanical, elastic, optical, and magnetic properties. A critical and excellently organized cpmpilation based on these data appeared in 1969 with the publica tion of Landolt-Bornstein, Volume 111/3. This superb tabulation gave instant access to the results in the literature on nearly 450 pure substances and solid solutions of ferroelectric and antiferroelectric materials. Continuing interest in ferroelectrics, spurred by the growing importance of electrooptic crystals, resulted in the publication of almost as many additional papers by the end of 1969 as had been surveyed in Landolt-Bornstein.
Recently, environmental scientists have been required to perform a new type of assessment-ecological risk assessment. This is the first book that explains how to perform ecological risk assessments and gives assessors access to the full range of useful data, models, and conceptual approaches they need to perform an accurate assessment. It explains how ecological risk assessment relates to more familiar types of assessments. It also shows how to organize and conduct an ecological risk assessment, including defining the source, selecting endpoints, describing the relevant features of the receiving environment, estimating exposure, estimating effects, characterizing the risks, and interacting with the risk manager. Specific technical topics include finding and selecting toxicity data; statistical and mathematical models of effects on organisms, populations, and ecosystems; estimation of chemical fate parameters; modeling of chemical transport and fate; estimation of chemical uptake by organisms; and estimation, propagation, and presentation of uncertainty. Ecological Risk Assessment also covers conventional risk assessments, risk assessments for existing contamination, large scale problems, exotic organisms, and risk assessments based on environmental monitoring. Environmental assessors at regulatory agencies, consulting firms, industry, and government labs need this book for its approaches and methods for ecological risk assessment. Professors in ecology and other environmental sciences will find the book's practical preparation useful for classroom instruction. Environmental toxicologists and chemists will appreciate the discussion of the utility for risk assessment of particular toxicity tests and chemical determinations.
Oak Ridge, Tennessee, was created by the U.S. government during World War II to aid in the construction of the first atomic bomb. Drawing on oral history and previously classified material, this book portrays the patterns of daily life in this unique setting.
This is the story of the young women of Oak Ridge, Tennessee, who unwittingly played a crucial role in one of the most significant moments in U.S. history. The Tennessee town of Oak Ridge was created from scratch in 1942. One of the Manhattan Project's secret cities. All knew something big was happening at Oak Ridge, but few could piece together the true nature of their work until the bomb "Little Boy" was dropped over Hiroshima, Japan, and the secret was out. The reverberations from their work there, work they did not fully understand at the time, are still being felt today.
A town with a significant place in American history as the Birthplace of the Atomic Bomb, this pictorial history takes a visual journey pre-war and post. Nestled in the foothills of East Tennessee, 25 miles west of Knoxville, is a small town bordered on three sides by the Clinch River. The land first existed under other names - Elza, Robertsville, Scarboro, and Wheat - but in 1942, 59,000 acres of this unassuming rural land were transformed in a matter of weeks into a "secret city" that became known as the mysterious Manhattan District. As a direct result of the letter written by Albert Einstein to President Franklin D. Roosevelt in 1939, the Manhattan District was created to develop new atomic weapons. Finally named Oak Ridge in 1943 and now thriving with a population of over 27,000, the town continues to be a significant center for the advancement of science and technology used throughout the world. In this pictorial history, photographs and personal descriptions guide readers on a visual journey of the construction of a city and the creation of the atomic bomb, to the post-war transformation of Oak Ridge into a major scientific community in the South.
This volume is a joint effort of the Research Materials Information Center (RMIC) of the Solid State Division at Oak Ridge National Laboratory and the Libraries and Information Systems Center at Bell Telephone Laboratories (BTL) Murray Hill, N. J. The Research Materials Information Center has, since 1963, been answering inquiries on the avail ability, preparation, and properties of inorganic solid-state research materials. The preparation of bibliographies has been essential to this function, and the interest in ferroelectrics led to the compila tion of the journal and report literature on that subject. The 1962 book Ferroelectric Crystals, by Jona and Shirane, was taken as a cutoff point, and all papers through mid-1969 received by the Center have been included. The Libraries and Information Systems Center of BTL has, over a period of years, developed a proprie tary package of computer programs called BELDEX, which formats and generates indexes to biblio graphic material. This group therefore undertook to process RMIC's ferroelectric references by BELDEX so that both laboratories could have the benefit of an indexed basic bibliography in this important research area.
