DOWNLOAD EBOOKThe Sword and the Shield is based on one of the most extraordinary intelligence coups of recent times: a secret archive of top-level KGB documents smuggled out of the Soviet Union which the FBI has described, after close examination, as the "most complete and extensive intelligence ever received from any source." Its presence in the West represents a catastrophic hemorrhage of the KGB's secrets and reveals for the first time the full extent of its worldwide network. Vasili Mitrokhin, a secret dissident who worked in the KGB archive, smuggled out copies of its most highly classified files every day for twelve years. In 1992, a U.S. ally succeeded in exfiltrating the KGB officer and his entire archive out of Moscow. The archive covers the entire period from the Bolshevik Revolution to the 1980s and includes revelations concerning almost every country in the world. But the KGB's main target, of course, was the United States. Though there is top-secret material on almost every country in the world, the United States is at the top of the list. As well as containing many fascinating revelations, this is a major contribution to the secret history of the twentieth century. Among the topics and revelations explored are: The KGB's covert operations in the United States and throughout the West, some of which remain dangerous today. KGB files on Oswald and the JFK assassination that Boris Yeltsin almost certainly has no intention of showing President Clinton. The KGB's attempts to discredit civil rights leader in the 1960s, including its infiltration of the inner circle of a key leader. The KGB's use of radio intercept posts in New York and Washington, D.C., in the 1970s to intercept high-level U.S. government communications. The KGB's attempts to steal technological secrets from major U.S. aerospace and technology corporations. KGB covert operations against former President Ronald Reagan, which began five years before he became president. KGB spies who successfully posed as U.S. citizens under a series of ingenious disguises, including several who attained access to the upper echelons of New York society.

DOWNLOAD EBOOKThe COVID-19 pandemic has presented unprecedented challenges to the nation's K-12 education system. The rush to slow the spread of the virus led to closures of schools across the country, with little time to ensure continuity of instruction or to create a framework for deciding when and how to reopen schools. States, districts, and schools are now grappling with the complex and high-stakes questions of whether to reopen school buildings and how to operate them safely if they do reopen. These decisions need to be informed by the most up-to-date evidence about the SARS-CoV-2 virus that causes COVID-19; about the impacts of school closures on students and families; and about the complexities of operating school buildings as the pandemic persists. Reopening K-12 Schools During the COVID-19 Pandemic: Prioritizing Health, Equity, and Communities provides guidance on the reopening and operation of elementary and secondary schools for the 2020-2021 school year. The recommendations of this report are designed to help districts and schools successfully navigate the complex decisions around reopening school buildings, keeping them open, and operating them safely.

DOWNLOAD EBOOKThis volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient. Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also: Reviews selected components of food that may influence the bioavailability of these compounds. Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role. Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.

DOWNLOAD EBOOKForced Migration, first published in 1982, examines the impact of the slave trade on Africa. There has been much debate over recent years about the effect of the Atlantic slave trade on Africa, with some authorities claiming that there were huge figures involved, and that these set back Africa's development for many years. Other historians reach lower estimates of the figures involved in the Atlantic trade, and hence argue that the effects on the political economy of Africa were more limited. Had widespread slavery existed long before the growth of the European slave trade? How important was the trans-Saharan traffic? Dr Inikori is the most authoritative voice in Africa to take part in this controversial international debate. He has done much original research into records, and here has made and introduced a selection of key papers. He has added elucidating editorial comments that place each paper in its context and link it to the other contributions.

DOWNLOAD EBOOKCarbohydrate Chemistry provides review coverage of all publications relevant to the chemistry of monosaccharides and oligosaccharides in a given year. The amount of research in this field appearing in the organic chemical literature is increasing because of the enhanced importance of the subject, especially in areas of medicinal chemistry and biology. In no part of the field is this more apparent than in the synthesis of oligosaccharides required by scientists working in glycobiology. Clycomedicinal chemistry and its reliance on carbohydrate synthesis is now very well established, for example, by the preparation of specific carbohydrate- based antigens, especially cancer-specific oligosaccharides and glycoconjugates. Coverage of topics such as nucleosides, amino-sugars, alditols and cyclitols also covers much research of relevance to biological and medicinal chemistry. Each volume of the series brings together references to all published work in given areas of the subject and serves as a comprehensive database for the active research chemist Specialist Periodical Reports provide systematic and detailed review coverage in major areas of chemical research. Compiled by teams of leading authorities in the relevant subject areas, the series creates a unique service for the active research chemist, with regular, in-depth accounts of progress in particular fields of chemistry. Subject coverage within different volumes of a given title is similar and publication is on an annual or biennial basis.

DOWNLOAD EBOOKNew observations of the period between the cosmic recombination and the end of reionization are posing intriguing questions about where the first generations of stars were formed, how the first galaxies were assembled, whether these galaxies have low redshift counterparts, and what role the early galaxies played in the reionization process. Combining the new observational data with theoretical models can shed new light on open issues regarding the star formation process, its role in the reionization of the Universe, and the metal enrichment in galaxies at those early epochs. This volume brings together leading experts in the field to discuss our current level of understanding and what may come in the near future as our observational as well as theoretical tools improve. The book confronts the theory of how the first stars, black holes, and galaxies formed with current and planned observations. This synthesis is very timely, just ahead of the establishment of major new facilities, such as the James Webb Space Telescope (JWST), a next-generation, millimeter/sub-millimeter observatory in the Atacama desert (ALMA), and ground-based Extremely Large Telescopes (ELT). Together, they will revolutionize the study of the most distant objects in the Universe. This volume is aimed at beginning graduate students but can also serve as a reference work for active researchers in the field. Apart from presenting the fundamental concepts involved, it also provides an introduction to the methods and techniques used. The book will also be useful to anyone with an astrophysical background who needs an effective starting point for learning about the first stars and galaxies.
