Mobile Genetic Elements by James Shapiro Pdf

Mobile Genetic Elements introduces the nonspecialist to the biology and genetics of mobile elements. It attempts to make the biochemistry of DNA rearrangements more accessible to embryologists and evolutionists, and to illuminate the related developmental cycles to the biochemist. The book also shows how natural the activity of mobile elements can be in diverse biological situations. The chapters describe several well-studied cases in which genetic determinants—often identified as specific nucleic acid sequences—repeatedly change their positions within or between cellular genomes. Because their genomic positions are not fixed, these determinants may conveniently be classed together under the rubric of mobile genetic elements. The book begins with a discussion of maize controlling elements. This is followed by separate chapters on the bacteriophages ? and Mu; nonviral mobile elements in bacteria; transposable Ty elements in brewer's yeast; Drosophila transposable element; and hybrid dysgenesis. Subsequent chapters cover vertebrate retroviruses; Agrobacterium oncogenesis in plants; flagellar phase variation in Salmonella; yeast mating type; and surface antigenic variation in trypanosomes.

Handbook of Superconducting Materials by David A. Cardwell,David S. Ginley Pdf

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

Advances in Superconductivity XII by T. Yamashita,K. Tanabe Pdf

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.

Archeology and Volcanism in Central America by Payson D. Sheets Pdf

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.

Feldspar Minerals by J.V. Smith Pdf

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.

Advances in Superconductivity X by Kozo Osamura,Izumi Hirabayashi Pdf

The International Symposium on Superconductivity, which has been held annu ally since 1988, is a forum for presenting the most up-to-date information about a broad range of research and development in superconductivity, from funda mental aspects to applications. More than 10 years have passed since the discovery of oxide superconductors and since various developments of applications began. It may be said that the prospects for application of oxide superconductors recently have opened up. Great progress has been made toward practical use, for example, of the flywheel, which uses bulk materials, and the high-performance cryo-cooled magnet made of bismuth wire. These were the results of persistent efforts to develop materials from the viewpoint of materials science and engineering. Also important is the progress in comprehensive understanding of high temperature superconductivity. Unique electronic properties of cuprates such as the non-Fermi liquid normal state, spin-charge separation, spin gap, and d-wave symmetry were discussed at the symposium, as were the unique electromagnetic properties resulting from the low dimensionality of cuprates. In the field of new superconductors, many exotic materials have been discovered since 1986. A decade of work with cuprate superconductors is reviewed in this proceedings, and several of the newest materials are presented. These papers will be instructive for many researchers and for students who are to enter this field.

Electronic Properties of High-Tc Superconductors by Hans Kuzmany,Michael Mehring,Jörg Fink Pdf

The International Winter School on Electronic Properties of High-Temperature Superconductors, held between March 7-14, 1992, in Kirchberg, (Tyrol) Austria, was the sixth in a series of meetings to be held at this venue. Four of the earlier meetings were dedicated to issues in the field of conducting polymers, while the winter school held in 1990 was devoted to the new discipline of high-T c superconductivity. This year's meeting constituted a forum not only for the large number of scientists engaged in high-Tc research, but also for those involved in the new and exciting field of fullerenes. Many of the issues raised during the earlier winter schools on conducting polymers, and the last one on high-T c superconductivity, have taken on a new significance in the light of the discovery of superconducting C materials. 60 The Kirchberg meetings are organized in the style of a school where expe rienced scientists from universities, research laboratories and industry have the opportunity to discuss their most recent results, and where students and young scientists can learn about the present status of research and applications from some of the most eminent workers in their field. In common with the previous winter school on high-Tc superconductors, the of the cuprate superconductors. present one focused on the electronic properties In addition, consideration was given to related compounds which are relevant to the understanding of the electronic structure of the cuprates in the normal state, to other oxide superconductors and to fulleride superconductors.

Untwine by Edwidge Danticat Pdf

“A genuinely moving exploration of the pain of separation” from the New York Times-bestselling author and National Book Award finalist (The New York Times Book Review). NAACP Image Awards Outstanding Literary Work 2015 VOYA Magazine Perfect Ten CCBC Choices List Selection Bank Street College of Education Best Children’s Books of the Year, 2016 New York Public Library Best Books for Teens Selection Giselle Boyer and her identical twin, Isabelle, are as close as sisters can be, even as their family seems to be unraveling. Then the Boyers have a tragic encounter that will shatter everyone’s world forever. Giselle wakes up in the hospital, injured and unable to speak or move. Trapped in the prison of her own body, Giselle must revisit her past in order to understand how the people closest to her—her friends, her parents, and above all, Isabelle, her twin—have shaped and defined her. Will she allow her love for her family and friends to lead her to recovery? Or will she remain lost in a spiral of longing and regret? Untwine is a spellbinding tale, lyrical and filled with love, mystery, humor, and heartbreak. Award-winning author Edwidge Danticat brings her extraordinary talent to this graceful and unflinching examination of the bonds of friendship, romance, family, the horrors of loss, and the strength we must discover in ourselves when all seems hopeless. “While Danticat fully grounds Giselle in her identity as a Haitian-American teen in Miami, this gentle young artist could speak to any teen anywhere coping with a major loss.” —The Philadelphia Inquirer
