Review of the Department of Defense Test Protocols for Combat Helmets considers the technical issues relating to test protocols for military combat helmets. At the request of the DOD Director of Operational Test and Evaluation, this report evaluates the adequacy of the Advanced Combat Helmet test protocol for both first article testing and lot acceptance testing, including its use of the metrics of probability of no penetration and the upper tolerance limit (used to evaluate backface deformation). The report evaluates appropriate use of statistical techniques in gathering data; adequacy of current helmet testing procedures; procedures for the conduct of additional analysis of penetration and backface deformation data; and scope of characterization testing relative to the benefit of the information obtained.
This readable and engaging book dispels myths, often based on Western bias, about the nutritional value, flavor, and yield of these African grains.
Designed as a tool for economic development, the volume is organized with increasing levels of detail to meet the needs of both lay and professional readers. The authors present the available information on where and how each grain is grown, harvested, and processed, and they list its benefits and limitations as a food source.
The authors describe "next steps" for increasing the use of each grain, outline research needs, and address issues in building commercial production.
Sidebars cover such interesting points as the potential use of gene mapping and other "high-tech" agricultural techniques on these grains.
This fact-filled volume will be of great interest to agricultural experts, entrepreneurs, researchers, and individuals concerned about restoring food production, environmental health, and economic opportunity in sub-Saharan Africa.

The committee identifies teachers, or classroom practitioners, as the key to change, while acknowledging that change at the classroom level is significantly impacted by overarching public policies. How People Learn: Bridging Research and Practice highlights three key findings about how students gain and retain knowledge and discusses the implications of these findings for teaching and teacher preparation. The highlighted principles of learning are applicable to teacher education and professional development programs as well as to K-12 education. The research-based messages found in this book are clear and directly relevant to classroom practice. It is a useful guide for teachers, administrators, researchers, curriculum specialists, and educational policy makers.
Oceanography and Mine Warfare examines the following issues: (1) how environmental data are used in current mine warfare doctrine, (2) current procedures for in situ collection of data, (3) the present capabilities of the Navy's oceanographic community to provide supporting information for mine warfare operations, and (4) the ability of oceanographic research and technology developments to enhance current mine warfare capabilities. This report primarily concentrates on the importance of oceanographic data for mine countermeasures.
To provide a context for this analysis of present and proposed U.S. boost-phase and non-boost missile defense concepts and systems, the committee considered the following to be the missions for ballistic missile defense (BMD): protecting of the U.S. homeland against nuclear weapons and other weapons of mass destruction (WMD); or conventional ballistic missile attacks; protection of U.S. forces, including military bases, logistics, command and control facilities, and deployed forces, including military bases, logistics, and command and control facilities. They also considered deployed forces themselves in theaters of operation against ballistic missile attacks armed with WMD or conventional munitions, and protection of U.S. allies, partners, and host nations against ballistic-missile-delivered WMD and conventional weapons.
Consistent with U.S. policy and the congressional tasking, the committee conducted its analysis on the basis that it is not a mission of U.S. BMD systems to defend against large-scale deliberate nuclear attacks by Russia or China. Making Sense of Ballistic Missile Defense: An Assessment of Concepts and Systems for U.S. Boost-Phase Missile Defense in Comparison to Other Alternatives suggests that great care should be taken by the U.S. in ensuring that negotiations on space agreements not adversely impact missile defense effectiveness. This report also explains in further detail the findings of the committee, makes recommendations, and sets guidelines for the future of ballistic missile defense research.
