When a twin dies during pregnancy, this experience can leave a vague but profound sense of loss in the mind of the survivor. In this book is reflected current, ground-breaking research into the death of a twin, both at birth and before, plus stories and poetry written by the survivors themselves. This extraordinary collection of twenty articles about the death of a twin from a variety of perspectives reveals the astonishing truth of how it can actually feel to be the survivor when your twin has died in the womb. Recent research has shown that as many as one in eight people are the sole survivors of a twin pregnancy, and many of them have no proof of ever having had a twin. Ultrasound scanning now reveals that many more tiny twins are lost in the womb than was ever thought possible. The editor is Althea Hayton, who is director of "wombtwin.com," an internet- based research project. She provides information, help and psychological support for the sole survivors of twin or multiple pregnancies. Michael J. Shea, Ph.D. of the Santa Barbara Graduate Institute says about this book; "This is a great addition to a psychological understanding of prenatal development and gives a comprehensive view from a wide variety of experts in the field. A must read for anyone interested in pre- and perinatal psychology, and especially anyone who thinks they may have had a twin." Some of these chapters will be of particular interest to pregnant women who have experienced "vanishing twin" syndrome. Therapists and psychologists who are studying the pre-birth origins of various psychological conditions such as depression, blocked grieving or suicidal thoughts will find the case studies in this book very enlightening. The personal accounts of the loss of a twin before birth are of interest to all, and raise some important issues about the nature of pre-born consciousness. It seems that we all carry some vague impressions of our life in the womb, and surviving twins have a particularly interesting story to tell.

With the advent of High Temperature Superconductivity and the increasing reliability of fabrication techniques, superconductor technology has moved firmly into the mainstream of academic and industrial research. There is currently no single source of practical information giving guidance on which technique to use for any particular category of superconductor. An increasing number of materials scientists and electrical engineers require easy access to practical information, sensible advice and guidance on 'best-practice' and reliable, proven fabrication and characterisation techniques.The Handbook will be the definitive collection of material describing techniques for the fabrication and analysis of superconducting materials. In addition to the descriptions of techniques, authoritative discussions written by leading researchers will give guidance on the most appropriate technique for a particular situation.Characterisation and measurement techniques will form an important part of the Handbook, providing researchers with a standard reference for experimental techniques. The tutorial style description of these techniques makes the Handbook particularly suitable for use by graduate students.The Handbook will be supported by a comprehensive web site which will be updated with new data as it emerges.The Handbook has six main sections: -- Fundamentals of Superconductivity - characteristic properties, elementary theory, critical current of type II superconductors-- Processing - bulk materials, wires and tapes, thick and think films, contact techniques-- Characterisation Techniques - structure/microstructure, measurement and interpretation of electromagnetic properties,measurement of physics properties-- Materials - characteristic properties of low and high Tc materials-- Applications - high current applications, trapped flux devices, high frequency devices, josephson junction devic

The 12th International Symposium on Superconductivity was held in Morioka, Japan, October 17-19, 1999. Convened annually since 1988, the symposium covers the whole field of superconductivity from fundamental physics and chemistry to a variety of applications. At the 12th Symposium, a mini-symposium focusing on the two-dimensionality of high-temperature superconductors, or the c-axis transport, and a session on vortex physics were organized. There were also many reports on the recent developments of YBCO-based coated conductors both in the United States and in Japan, AC losses of wires and tapes, developments of bulk materials with strong flux pinning, the recent progress in thin film and junction technologies, and the demonstration of various electronics applications using SQUIDs, microwave devices, and single-flux-quantum (SFQ) digital devices. This volume is a valuable resource for all those working in the field of superconductivity.

Scientists have long speculated on the impact of extreme natural catastrophes on human societies. Archeology and Volcanism in Central America provides dramatic evidence of the effects of several volcanic disasters on a major civilization of the Western Hemisphere, that of the Maya. During the past 2,000 years, four volcanic eruptions have taken place in the Zapotitán Valley of southern El Salvador. One, the devastating eruption of Ilopango around A.D. 300, forced a major migration, pushing the Mayan people north to the Yucatán Peninsula. Although later eruptions did not have long-range implications for cultural change, one of the subsequent eruptions preserved the Cerén site—a Mesoamerican Pompeii where the bodies of the villagers, the palm-thatched roofs of their houses, the pots of food in their pantries, even the corn plants in their fields were preserved with remarkable fidelity. Throughout 1978, a multidisciplinary team of anthropologists, archeologists, geologists, biologists, and others sponsored by the University of Colorado's Protoclassic Project researched and excavated the results of volcanism in the Zapotitan Valley—a key Mesoamerican site that contemporary political strife has since rendered inaccessible. The result is an outstanding contribution to our understanding of the impact of volcanic eruptions on early Mayan civilization. These investigations clearly demonstrate that the Maya inhabited this volcanically hazardous valley in order to reap the short-term benefits that the volcanic ash produced—fertile soil, fine clays, and obsidian deposits.

33 14. 3. 5 REE between Plagioclase and Aqueous Fluid 0 Cullers et al. (1973) measured the distribution of REE at 850 C and 750 bars pressure between a natural plagioclase, An , and gaseous water. The rare earths 65 favored the plagioclase by a factor which varies from about 25 for Ce to 10 for Lu. Data were also obtained for forsterite, diopside, enstatite and two rhyolite glasses, on the one hand, and water on the other hand, thereby permitting estimation of the partition coefficients between all pairs of phases. 14. 4 Chemical Substitution in Natural Feldspars 14. 4. 1 Introduction It is quite impracticable to give all the data on chemical substitution in natural feldspars: indeed many of the details are significant only to some particular pegmatite or rock body. As far as possible, emphasis is placed on features of general interest to crystal chemists and to petrologists. Ironically the well established features can be described more easily than the uncertain ones, and unfortunately it is necessary to use valuable space on data of dubious value. The bibliography is fairly complete, but it was impracticable to locate all data, especially those in obscure journals. Each reference is followed by a list of the elements referred to in the paper, thereby permitting a reader to compile a fairly compre hensive set of references on any chosen element. Not all papers are mentioned in the text. The book on Geochemistry and Mineralogy of Rare Elements, etc.
