Uninhabited Air Vehicles: Enabling Science for Military Systems
by Committee on Materials Structures Aeronautics for Advanced Uninhabited Air VehiclesU.S. Air Force (USAF) planners have envisioned that uninhabited air vehicles (UAVs), working in concert with inhabited vehicles, will become an integral part of the future force structure. Current plans are based on the premise that UAVs have the potential to augment, or even replace, inhabited aircraft in a variety of missions. However, UAV technologies must be better understood before they will be accepted as an alternative to inhabited aircraft on the battlefield. The U.S. Air Force Office of Scientific Research (AFOSR) requested that the National Research Council, through the National Materials Advisory Board and the Aeronautics and Space Engineering Board, identify long-term research opportunities for supporting the development of technologies for UAVs. The objectives of the study were to identify technological developments that would improve the performance and reliability of “generation-after-next” UAVs at lower cost and to recommend areas of fundamental research in materials, structures, and aeronautical technologies. The study focused on innovations in technology that would “leapfrog” current technology development and would be ready for scaling-up in the post-2010 time frame (i.e., ready for use on aircraft by 2025).

United Arab Emirates Keys to Soil Taxonomy
by Shabbir A. Shahid Mahmoud A. Abdelfattah Michael A. Wilson John A. Kelley Joseph V. ChiarettiCentral to human life and civilization, soils are an integral part of the physical and cultural environment. Although we may take them for granted, the rise and fall of civilizations is closely linked with the use and abuse of soil and water resources. It is therefore important to evaluate soils for their quality and link them to appropriate uses and services. This book provides information on soil classification and shows how to key out taxa relevant to UAE soils. The latest soil inventory of United Arab Emirates reveals that a rather uniform looking desert landscape has, in fact, a diversity of subsurface features. These features confirm the soil diversity in terms of classification, chemistry, physics, mineralogy, fertility, suitability for different uses and vulnerability to land degradation. United Arab Emirates Keys to Soil Taxonomy presents information for keying out the soils of the United Arab Emirates into separate classes and provides a guide to associated laboratory methods. The classification used predominantly is extracted from the 11th edition of the USDA-NRCS Keys to Soil Taxonomy, and sections relevant to the soils found in the UAE are included here. Primarily, this key is designed to fit the soil system of the United Arab Emirates. Information not found in the USDA key has been added, including criteria and classes for: 1) differentiating anhydritic soils from gypsic soils, 2) identifying "lithic" subgroups for Aquisalids and Haplosalids, 3) identifying "salidic" subgroups within the great groups of Gypsids, Calcids, Psamments, and Orthents, and 4) incorporation of phases for soil taxa. A subsurface diagnostic horizon and mineralogy class (anhydritic), not reported earlier in the world soil literature and, recently found in the UAE, has also been added to the book. The book also offers a mechanism for updating the current soil surveys, and will facilitate the correlation of soils from new surveys in the UAE. Additionally, it will help the international soil science community to converse about UAE soils, and facilitate comparison to soils of other regions. These linkages allow countries with similar mapping and classification procedures and similar soils to transfer agriculture technology without conducting long-term experiments under similar environmental conditions, especially for Gulf Cooperation Council countries (Bahrain, Kuwait, Qatar, Oman, and Saudi Arabia).
The United Nations World Water Development Report 3: Water in a Changing World (Two Vols.)
by World Water World Water Assessment ProgrammeThe United Nations World Water Development Report, published every three years, is a comprehensive review providing an authoritative picture of the state of the world's freshwater resources. It offers best practices as well as in-depth theoretical analyses to help stimulate ideas and actions for better stewardship in the water sector. It is the only report of its kind, resulting from the collaboration and contributions of the 26 UN agencies, commissions, program, funds, secretariats and conventions that have a significant role in addressing global water concerns. The news media are full of talk of crises - in climate change, energy and food and troubled financial markets. These crises are linked to each other and to water resources management. Unresolved, they may lead to increasing political insecurity and conflict. Water is required to meet our fundamental needs and rising living standards and to sustain our planet‘s fragile ecosystems. Pressures on the resource come from a growing and mobile population, social and cultural change, economic development and technological change. Adding complexity and risk is climate change, with impacts on the resource as well as on the sources of pressure on water. The challenges, though substantial, are not insurmountable. The Report shows how some countries have responded. Progress in providing drinking water is heartening, with the Millennium Development Goal target on track in most regions. But other areas remain unaddressed, and after decades of inaction, the problems in water systems are enormous and will worsen if left unattended. Leaders in the water sector can inform decisions outside their domain and manage water resources to achieve agreed socioeconomic objectives and environmental integrity. Leaders in government, the private sector and civil society determine these objectives and allocate human and financial resources to meet them. Recognizing this responsibility, they must act now! Two volume set: 336
The United States and Europe: Beyond the Neo-Conservative Divide? (Contemporary Security Studies)
by Jon Roper John BaylisA penetrating new examination of the triangular political and cultural relationship between America, Britain, and continental Europe. This relationship is both fraught and dynamic. Post-war reconstruction of Europe brought integration. Creating a ‘United States of Europe’ was a goal shared by many Americans. Yet the contemporary 'War on Terror', has redefined relationships between America, Britain, 'old' and 'new' Europe. For Britain, the Channel seems wider than the Atlantic, although geopolitically it is part of Europe. This book brings together experts from Britain, Europe and America to explore the complexities of contemporary cultural and political relationships, considering the challenges that have been met and those that have to be faced.

Uniting Electron Crystallography and Powder Diffraction
by Anatoly Avilov Kenneth Shankland Louisa Meshi Ute Kolb William I.F DavidThe polycrystalline and nanocrystalline states play an increasingly important role in exploiting the properties of materials, encompassing applications as diverse as pharmaceuticals, catalysts, solar cells and energy storage. A knowledge of the three-dimensional atomic and molecular structure of materials is essential for understanding and controlling their properties, yet traditional single-crystal X-ray diffraction methods lose their power when only polycrystalline and nanocrystalline samples are available. It is here that powder diffraction and single-crystal electron diffraction techniques take over, substantially extending the range of applicability of the crystallographic principles of structure determination. This volume, a collection of teaching contributions presented at the Crystallographic Course in Erice in 2011, clearly describes the fundamentals and the state-of-the-art of powder diffraction and electron diffraction methods in materials characterisation, encompassing a diverse range of disciplines and materials stretching from archeometry to zeolites. As such, it is a comprehensive and valuable resource for those wishing to gain an understanding of the broad applicability of these two rapidly developing fields.
