Animal Biotechnology: Science-based Concerns

by National Research Council

Genetic-based animal biotechnology has produced new food and pharmaceutical products and promises many more advances to benefit humankind. These exciting prospects are accompanied by considerable unease, however, about matters such as safety and ethics. This book identifies science-based and policy-related concerns about animal biotechnology—key issues that must be resolved before the new breakthroughs can reach their potential.The book includes a short history of the field and provides understandable definitions of terms like cloning. Looking at technologies on the near horizon, the authors discuss what we know and what we fear about their effects—the inadvertent release of dangerous microorganisms, the safety of products derived from biotechnology, the impact of genetically engineered animals on their environment. In addition to these concerns, the book explores animal welfare concerns, and our societal and institutional capacity to manage and regulate the technology and its products. This accessible volume will be important to everyone interested in the implications of the use of animal biotechnology.

Application of Lightweighting Technology to Military Vehicles, Vessels, and Aircraft

by National Research Council Division on Engineering and Physical Sciences National Materials and Manufacturing Board Committee on Benchmarking the Technology and Application of Lightweighting

Lightweighting is a concept well known to structural designers and engineers in all applications areas, from laptops to bicycles to automobiles to buildings and airplanes. Reducing the weight of structures can provide many advantages, including increased energy efficiency, better design, improved usability, and better coupling with new, multifunctional features. While lightweighting is a challenge in commercial structures, the special demands of military vehicles for survivability, maneuverability and transportability significantly stress the already complex process. Application of Lightweighting Technology to Military Vehicles, Vessels, and Aircraft assesses the current state of lightweighting implementation in land, sea, and air vehicles and recommends ways to improve the use of lightweight materials and solutions. This book considers both lightweight materials and lightweight design; the availability of lightweight materials from domestic manufacturers; and the performance of lightweight materials and their manufacturing technologies. It also considers the "trade space"--that is, the effect that use of lightweight materials or technologies can have on the performance and function of all vehicle systems and components. This book also discusses manufacturing capabilities and affordable manufacturing technology to facilitate lightweighting. Application of Lightweighting Technology to Military Vehicles, Vessels, and Aircraft will be of interest to the military, manufacturers and designers of military equipment, and decision makers.

Applying Advanced Information Systems To Ports And Waterways Management

by National Research Council

The future safety of maritime transportation in the United States-a major factor in the nation's international trade and economic well-being-will depend heavily on the quality of port and waterways information systems. <P><P>Many U.S. ports and waterways lack adequate information services, although certain elements of advanced systems are now available in some locations. Barriers to improvements in information systems include the division of responsibilities for waterways management among multiple agencies at all levels of government, a lack of coordination among the federal agencies responsible for waterways management, inadequate budgets for some critical maritime programs, the high costs of some specialized technologies, stakeholder opposition to user fees, limited access to certain key data, the incompatibility of many independently developed systems, and the absence of standards for some attractive technologies.

Arsenic in Drinking Water

by National Research Council

The U.S. Environmental Protection Agency (EPA) has been considering a more stringent regulation of arsenic in water. A significant reduction in the maximum contaminant level (MCL) could increase compliance costs for water utilities. This book discusses the adequacy of the current EPA MCL for protecting human health in the context of stated EPA policy and provides an unbiased scientific basis for deriving the arsenic standard for drinking water and surface water.Arsenic in Drinking Water evaluates epidemiological data on the carcinogenic and noncarcinogenic health effects of arsenic exposure of Taiwanese populations and compares those effects with the effects of arsenic exposure demonstrated in other countries&mdash;including the United States.The book also reviews data on toxicokinetics, metabolism, and mechanism and mode of action of arsenic to ascertain how these data could assist in assessing human health risks from arsenic exposures. This volume recommends specific changes to improve the toxicity analyses and risk characterization. The implications of the changes for EPA&rsquo;s current MCL for arsenic are also described.

Assessing Risks to Endangered and Threatened Species from Pesticides

by National Research Council Division on Earth and Life Studies Board on Environmental Studies and Toxicology Committee on Ecological Risk Assessment Under FIFRA and ESA

The US Fish and Wildlife Service (FWS) and the National Marine Fisheries Service (NMFS) are responsible for protecting species that are listed as endangered or threatened under the Endangered Species Act (ESA) and for protecting habitats that are critical for their survival. The US Environmental Protection Agency (EPA) is responsible for registering or reregistering pesticides under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and must ensure that pesticide use does not cause any unreasonable adverse effects on the environment, which is interpreted to include listed species and their critical habitats. The agencies have developed their own approaches to evaluating environmental risk, and their approaches differ because their legal mandates, responsibilities, institutional cultures, and expertise differ. Over the years, the agencies have tried to resolve their differences but have been unsuccessful in reaching a consensus regarding their assessment approaches. As a result, FWS, NMFS, EPA, and the US Department of Agriculture asked the National Research Council (NRC) to examine scientific and technical issues related to determining risks posed to listed species by pesticides. Specifically, the NRC was asked to evaluate methods for identifying the best scientific data available; to evaluate approaches for developing modeling assumptions; to identify authoritative geospatial information that might be used in risk assessments; to review approaches for characterizing sublethal, indirect, and cumulative effects; to assess the scientific information available for estimating effects of mixtures and inert ingredients; and to consider the use of uncertainty factors to account for gaps in data. Assessing Risks to Endangered and Threatened Species from Pesticides, which was prepared by the NRC Committee on Ecological Risk Assessment under FIFRA and ESA, is the response to that request.

Assessing the Reliability of Complex Models

by National Research Council Division on Engineering and Physical Sciences Board on Mathematical Sciences And Their Applications Committee on Mathematical Foundations of Verification, Validation, and Uncertainty Quantification

Advances in computing hardware and algorithms have dramatically improved the ability to simulate complex processes computationally. Today's simulation capabilities offer the prospect of addressing questions that in the past could be addressed only by resource-intensive experimentation, if at all. Assessing the Reliability of Complex Models recognizes the ubiquity of uncertainty in computational estimates of reality and the necessity for its quantification. As computational science and engineering have matured, the process of quantifying or bounding uncertainties in a computational estimate of a physical quality of interest has evolved into a small set of interdependent tasks: verification, validation, and uncertainty of quantification (VVUQ). In recognition of the increasing importance of computational simulation and the increasing need to assess uncertainties in computational results, the National Research Council was asked to study the mathematical foundations of VVUQ and to recommend steps that will ultimately lead to improved processes. Assessing the Reliability of Complex Models discusses changes in education of professionals and dissemination of information that should enhance the ability of future VVUQ practitioners to improve and properly apply VVUQ methodologies to difficult problems, enhance the ability of VVUQ customers to understand VVUQ results and use them to make informed decisions, and enhance the ability of all VVUQ stakeholders to communicate with each other. This report is an essential resource for all decision and policy makers in the field, students, stakeholders, UQ experts, and VVUQ educators and practitioners.

Assessment of Inertial Confinement Fusion Targets

by National Research Council Division on Engineering and Physical Sciences Board on Physics and Astronomy Board on Energy and Environmental Systems Panel on the Assessment of Inertial Confinement Fusion Targets

In the fall of 2010, the Office of the U.S. Department of Energy's (DOE's) Secretary for Science asked for a National Research Council (NRC) committee to investigate the prospects for generating power using inertial confinement fusion (ICF) concepts, acknowledging that a key test of viability for this concept--ignition --could be demonstrated at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) in the relatively near term. The committee was asked to provide an unclassified report. However, DOE indicated that to fully assess this topic, the committee's deliberations would have to be informed by the results of some classified experiments and information, particularly in the area of ICF targets and nonproliferation. Thus, the Panel on the Assessment of Inertial Confinement Fusion Targets ("the panel") was assembled, composed of experts able to access the needed information. The panel was charged with advising the Committee on the Prospects for Inertial Confinement Fusion Energy Systems on these issues, both by internal discussion and by this unclassified report. A Panel on Fusion Target Physics ("the panel") will serve as a technical resource to the Committee on Inertial Confinement Energy Systems ("the Committee") and will prepare a report that describes the R&D challenges to providing suitable targets, on the basis of parameters established and provided to the Panel by the Committee. The Panel on Fusion Target Physics will prepare a report that will assess the current performance of fusion targets associated with various ICF concepts in order to understand: 1. The spectrum output; 2. The illumination geometry; 3. The high-gain geometry; and 4. The robustness of the target design. The panel addressed the potential impacts of the use and development of current concepts for Inertial Fusion Energy on the proliferation of nuclear weapons information and technology, as appropriate. The Panel examined technology options, but does not provide recommendations specific to any currently operating or proposed ICF facility.

Assessment of Planetary Protection Requirements for Spacecraft Missions to Icy Solar System Bodies

by National Research Council Space Studies Board Division on Engineering and Physical Sciences Committee on Planetary Protection Standards for Icy Bodies in the Outer Solar System

NASA's exploration of planets and satellites during the past 50 years has led to the discovery of traces of water ice throughout the solar system and prospects for large liquid water reservoirs beneath the frozen ICE shells of multiple satellites of the giant planets of the outer solar system. During the coming decades, NASA and other space agencies will send flybys, orbiters, subsurface probes, and, possibly, landers to these distant worlds in order to explore their geologic and chemical context. Because of their potential to harbor alien life, NASA will select missions that target the most habitable outer solar system objects. This strategy poses formidable challenges for mission planners who must balance the opportunity for exploration with the risk of contamination by Earth's microbes, which could confuse the interpretation of data obtained from these objects. The 2000 NRC report Preventing the Forward Contamination of Europa provided a criterion that was adopted with prior recommendations from the Committee on Space Research of the International Council for Science. This current NRC report revisits and extends the findings and recommendations of the 2000 Europa report in light of recent advances in planetary and life sciences and, among other tasks, assesses the risk of contamination of icy bodies in the solar system.

Assessment of Staffing Needs of Systems Specialists in Aviation

by National Research Council Division on Behavioral and Social Sciences and Education Board on Human-Systems Integration Committee on Staffing Needs of Systems Specialists in Aviation

Within the Federal Aviation Administration (FAA), the Airway Transportation System Specialists ATSS) maintain and certify the equipment in the National Airspace System (NAS).In fiscal year 2012, Technical Operations had a budget of $1.7B. Thus, Technical Operations includes approximately 19 percent of the total FAA employees and less than 12 percent of the $15.9 billion total FAA budget. Technical Operations comprises ATSS workers at five different types of Air Traffic Control (ATC) facilities: (1) Air Route Traffic Control Centers, also known as En Route Centers, track aircraft once they travel beyond the terminal airspace and reach cruising altitude; they include Service Operations Centers that coordinate work and monitor equipment. (2) Terminal Radar Approach Control (TRACON) facilities control air traffic as aircraft ascend from and descend to airports, generally covering a radius of about 40 miles around the primary airport; a TRACON facility also includes a Service Operations Center. (3) Core Airports, also called Operational Evolution Partnership airports, are the nation's busiest airports. (4) The General National Airspace System (GNAS) includes the facilities located outside the larger airport locations, including rural airports and equipment not based at any airport. (5) Operations Control Centers are the facilities that coordinate maintenance work and monitor equipment for a Service Area in the United States. At each facility, the ATSS execute both tasks that are scheduled and predictable and tasks that are stochastic and unpredictable in. These tasks are common across the five ATSS disciplines: (1) Communications, maintaining the systems that allow air traffic controllers and pilots to be in contact throughout the flight; (2) Surveillance and Radar, maintaining the systems that allow air traffic controllers to see the specific locations of all the aircraft in the airspace they are monitoring; (3) Automation, maintaining the systems that allow air traffic controllers to track each aircraft's current and future position, speed, and altitude; (4) Navigation, maintaining the systems that allow pilots to take off, maintain their course, approach, and land their aircraft; and (5) Environmental, maintaining the power, lighting, and heating/air conditioning systems at the ATC facilities. Because the NAS needs to be available and reliable all the time, each of the different equipment systems includes redundancy so an outage can be fixed without disrupting the NAS. Assessment of Staffing Needs of Systems Specialists in Aviation reviews the available information on: (A) the duties of employees in job series 2101 (Airways Transportation Systems Specialist) in the Technical Operations service unit; (B) the Professional Aviation Safety Specialists (PASS) union of the AFL-CIO; (C) the present-day staffing models employed by the FAA; (D) any materials already produced by the FAA including a recent gap analysis on staffing requirements; (E) current research on best staffing models for safety; and (F) non-US staffing standards for employees in similar roles.

Assessment of Supercritical Water Oxidation System Testing for the Blue Grass Chemical Agent Destruction Pilot Plant

by National Research Council Board on Army Science and Technology Division on Engineering and Physical Sciences Committee to Assess Supercritical Water Oxidation System Testing for the Blue Grass Chemical Agent Destruction Pilot Plant

Assessment of Supercritical Water Oxidation System Testing for the Blue Grass Chemical Agent Destruction Pilot Plant reviews and evaluates the results of the tests conducted on one of the SCWO units to be provided to Blue Grass Chemical Agent Destruction Pilot Plant. The Army Element, Assembled Chemical Weapons Alternatives (ACWA) is responsible for managing the conduct of destruction operations for the remaining 10 percent of the nation's chemical agent stockpile, stored at the Blue Grass Army Depot (Kentucky) and the Pueblo Chemical Depot (Colorado). Facilities to destroy the agents and their associated munitions are currently being constructed at these sites. The Blue Grass Chemical Agent Destruction Pilot Plant (BGCAPP) will destroy chemical agent and some associated energetic materials by a process of chemical neutralization known as hydrolysis. The resulting chemical waste stream is known as hydrolysate. Among the first-of-a-kind equipment to be installed at BGCAPP are three supercritical water oxidation (SCWO) reactor systems. These particular hydrolysate feeds present unique non-agent-related challenges to subsequent processing via SCWO due to their caustic nature and issues of salt management.This report provides recommendations on SCWO systemization testing inclusive of durability testing and discusses systemization testing objectives and concepts.

An Assessment of the National Institute of Standards and Technology Manufacturing Engineering Laboratory

by National Research Council Division on Engineering and Physical Sciences Laboratory Assessments Board Panel on Manufacturing Engineering

The mission of the Manufacturing Engineering Laboratory (MEL) of the National Institute of Standards and Technology (NIST) is to promote innovation and the competitiveness of U.S. manufacturing through measurement science, measurement services, and critical technical contributions to standards. The MEL is organized in five divisions: Intelligent Systems, Manufacturing Metrology, Manufacturing Systems Integration, Precision Engineering, and Fabrication Technology. A panel of experts appointed by the National Research Council (NRC) assessed the first four divisions. Overall, this book finds that the four individual divisions are performing to the best of their ability, given available resources. In many areas in all four divisions, the capabilities and the work being performed are among the best in the field. However, reduced funding and other factors such as difficulty in hiring permanent staff are limiting (and are likely to increasingly limit) the degree to which MEL programs can achieve their objectives and are threatening the future impact of these programs.

An Assessment of the National Institute of Standards and Technology Materials Science and Engineering Laboratory

by National Research Council Division on Engineering and Physical Sciences Laboratory Assessments Board Panel on Materials Science and Engineering

The Materials Science and Engineering Laboratory (MSEL) of the National Institute of Standards and Technology (NIST) works with industry, standards bodies, universities, and other government laboratories to improve the nation's measurements and standards infrastructure for materials. A panel of experts appointed by the National Research Council (NRC) assessed the four divisions of MSEL, by visiting these divisions and reviewing their activities. This book concludes that, for the selected portion of the MSEL programs reviewed, the staff, the projects, and many facilities are outstanding. The projects are clearly focused on the mission of MSEL. The facilities and equipment are rationally upgraded within budget constraints, with several facilities being unique; the funding provided through the America COMPETES Act of 2007 is being used effectively. Division chiefs and staff evinced high morale, attributable to several factors: clear definitions of expectations and of the processes for realizing them, strong support of the MSEL from NIST leadership and of NIST generally from the President and from the Congress (through the American Competitiveness Initiative and the America COMPETES Act), and positive feedback from customers.

In this respect, the laboratory provides the foundation for the metrology of optical and ionizing radiations, time and frequency, and fundamental quantum processes, historically major areas of standards and technology. The Panel on Physics visited the six divisions of the laboratory and reviewed a selected sample of their programs and projects. This book finds that the overall quality and productivity of the Physics Laboratory are comparable to or better than those of other peer institutions, an accomplishment that is being achieved with an infrastructure that is smaller in both size and funding than the size and funding of most national and agency laboratories in the United States.

An Assessment of the Prospects for Inertial Fusion Energy

by National Research Council Division on Engineering and Physical Sciences Board on Physics and Astronomy Board on Energy and Environmental Systems Committee on the Prospects for Inertial Confinement Fusion Energy Systems

The potential for using fusion energy to produce commercial electric power was first explored in the 1950s. Harnessing fusion energy offers the prospect of a nearly carbon-free energy source with a virtually unlimited supply of fuel. Unlike nuclear fission plants, appropriately designed fusion power plants would not produce the large amounts of high-level nuclear waste that requires long-term disposal. Due to these prospects, many nations have initiated research and development (R&D) programs aimed at developing fusion as an energy source. Two R&D approaches are being explored: magnetic fusion energy (MFE) and inertial fusion energy (IFE). An Assessment of the Prospects for Inertial Fusion Energy describes and assesses the current status of IFE research in the United States; compares the various technical approaches to IFE; and identifies the scientific and engineering challenges associated with developing inertial confinement fusion (ICF) in particular as an energy source. It also provides guidance on an R&D roadmap at the conceptual level for a national program focusing on the design and construction of an inertial fusion energy demonstration plant.

Assessment to Enhance Air Force and Department of Defense Prototyping for the New Defense Strategy

by National Research Council Division on Engineering and Physical Sciences Air Force Studies Board Norman M. Haller Planning Committee for a Workshop on Assessment to Enhance Air Force and Department of Defense Prototyping for the New Defense Strategy

Assessment to Enhance Air Force and Department of Defense Prototyping for the New Defense Strategy is the summary of a workshop convened by the Air Force Studies Board of the National Academies' National Research Council in September 2013 to enhance Air Force and Department of Defense (DoD) prototyping for the new defense strategy. This workshop examined of a wide range of prototyping issues, including individual recommendations for a renewed prototype program, application of prototyping as a tool for technology/system development and sustainment (including annual funding), and positive and negative effects of a renewed program. Prototyping has historically been of great benefit to the Air Force and DoD in terms of risk reduction and concept demonstration prior to system development, advancing new technologies, workforce enhancement and skills continuity between major acquisitions, dissuasion of adversaries by demonstrating capabilities, maintaining technological surprise through classified technologies, and an overarching strategy of overall risk reduction during austere budget environments. Over the last two decades, however, many issues with prototyping have arisen. For example, the definitions and terminology associated with prototyping have been convoluted and budgets for prototyping have been used as offsets to remedy budget shortfalls. Additionally, prototyping has been done with no strategic intent or context, and both government and industry have misused prototyping as a key tool in the DoD and defense industrial base. Assessment to Enhance Air Force and Department of Defense Prototyping for the New Defense Strategy envisions a prototyping program that encourages innovation in new concepts and approaches and provides a means to assess and reduce risk before commitment to major new programs.

Assuring the U.S. Department of Defense a Strong Science, Technology, Engineering, and Mathematics (STEM) Workforce

by National Research Council National Academy of Engineering Division on Engineering and Physical Sciences Policy and Global Affairs Board on Higher Education and Workforce Committee on Science, Technology, Engineering, and Mathematics Workforce Needs for the U.S. Department of Defense and the U.S. Defense Industrial Base

The ability of the nation's military to prevail during future conflicts, and to fulfill its humanitarian and other missions, depends on continued advances in the nation's technology base. A workforce with robust Science, Technology, Engineering and Mathematics (STEM) capabilities is critical to sustaining U.S. preeminence. Today, however, the STEM activities of the Department of Defense (DOD) are a small and diminishing part of the nation's overall science and engineering enterprise. Assuring the U.S. Department of Defense a Strong Science, Technology, Engineering, and Mathematics (STEM) Workforce presents five principal recommendations for attracting, retaining, and managing highly qualified STEM talent within the department based on an examination of the current STEM workforce of DOD and the defense industrial base. As outlined in the report, DOD should focus its investments to ensure that STEM competencies in all potentially critical, emerging topical areas are maintained at least at a basic level within the department and its industrial and university bases.

Attitudes, Aptitudes, and Aspirations of American Youth: Implications for Military Recruitment

by National Research Council

Recruiting an all-volunteer military is a formidable task. To successfully enlist one eligible recruit, the Army must contact approximately 120 young people. The National Research Council explores the various factors that will determine whether the military can realistically expect to recruit an adequate fighting force -- one that will meet its upcoming needs. It also assesses the military's expected manpower needs and projects the numbers of youth who are likely to be available over the next 20 years to meet these needs. With clearly written text and useful graphics, Attitudes, Aptitudes, and Aspirations of American Youth offers an overview of important issues for military recruiters, touching on a number of important topics including: sex and race, education and aptitude, physical and moral attributes, and military life and working conditions. In addition, the book looks at how a potential recruit would approach the decision to enlist, considering personal, family, and social values, and the options for other employment or college. Building on the need to increase young Americans' propensity to enlist, this book offers useful recommendations for increasing educational opportunities while in the service and for developing advertising strategies that include concepts of patriotism and duty to country. Of primary value to military policymakers, recruitment officers, and analysts, Attitudes, Aptitudes, and Aspirations of American Youth will also interest social scientists and policy makers interested in youth trends.

Attracting PHDs to K-12 Education: A Demonstration Program for Science, Mathematics, and Technology

by National Research Council

The National Research Council (NRC) has undertaken a three-phase project to explore the possibility of a program to attract science, mathematics and engineering PhDs to careers in K-12 education. The first phase of the project surveyed the interests of recent PhDs in science and mathematics in pursuing careers in secondary education. Analysis of the Phase I data suggests that a significant percentage of PhDs might be interested in pursuing careers in secondary education under some circumstances. This report from the second phase of the project presents a proposal for a national demonstration program to determine how one might prepare PhDs to be productive members of the K-12 education community. The proposed program is designed to help meet the needs of the nation's schools, while providing further career opportunities for recent PhDs in science, mathematics and engineering.

Attracting Science And Mathematics Ph.d.s To Secondary School Education

by National Research Council

The National Research Council conducted a study to identify a set of incentives that state governments and local school districts can use to attract Ph.D. scientists and mathematicians to secondary school teaching positions. This project investigated the career ambitions of Ph.D.s in the physical and life sciences through focus groups and a national survey to determine the kinds of work conditions and compensation packages that would induce them to take positions teaching physics, chemistry, biology, and various electives in public high schools or positions developing secondary school science and mathematics curricula. The study conducted interviews with Ph.D.s who are already teaching in secondary schools to ascertain information from their experiences, with local school district administrators to assess what they are realistically willing to offer Ph.D. scientists to attract them, and with higher education administrators to explore programmatic changes they would need to institute to provide Ph.D.s with skills tailored to secondary school teaching. These investigations led to this report which describes the incentives local school districts could use in establishing pilot programs in this area.
