Specific heat loading in Nd:glass lasers (open access)

Specific heat loading in Nd:glass lasers

The specific thermal load parameter, chi, for xenon flashlamp-pumped Nd:glass gain media is written as a function of neodymium concentration, pump pulse duration, and energy extraction efficiency. The currently available data on radiative and nonradiative decay probabilities of several commercial Nd:glasses are used to calculate and graph specific thermal load parameter values. By factoring these results into performance scaling relationships for zig-zag and disk lasers, specific Nd:glasses can be selected for optimized laser performance.

Procedure for matching synfuel users with potential suppliers. Appendix B. Proposed and ongoing synthetic fuel production projects (open access)

Procedure for matching synfuel users with potential suppliers. Appendix B. Proposed and ongoing synthetic fuel production projects

To assist the Department of Energy, Office of Fuels Conversion (OFC), in implementing the synthetic fuel exemption under the Powerplant and Industrial Fuel Use Act (FUA) of 1978, Resource Consulting Group, Inc. (RCG), has developed a procedure for matching prospective users and producers of synthetic fuel. The matching procedure, which involves a hierarchical screening process, is designed to assist OFC in: locating a supplier for a firm that wishes to obtain a synthetic fuel exemption; determining whether the fuel supplier proposed by a petitioner is technically and economically capable of meeting the petitioner's needs; and assisting the Synthetic Fuels Corporation or a synthetic fuel supplier in evaluating potential markets for synthetic fuel production. A data base is provided in this appendix on proposed and ongoing synthetic fuel production projects to be used in applying the screening procedure. The data base encompasses a total of 212 projects in the seven production technologies.

Development of magnetic mirror systems for nuclear testing applications (open access)

Development of magnetic mirror systems for nuclear testing applications

Several system studies have concluded that the small size and steady state nature of magnetic mirror systems provide attractive features for nuclear-testing applications. The principle shortcoming of mirror systems is their small data base relative to that of tokamaks. This paper summarizes the present data base and describes experiments that could be carried out with small modifications of existing facilities to explore plasma physics issues associated with the production of high neutron fluxes in magnetic mirror configurations. The experiments would demonstrate physics principles important to such future applications of fusion power neutrons as blanket testing, tritium production, fissile fuel production, or decontamination of high-level radioactive nuclear-reactor wastes.

America Competes Act: NIST Applied Some Safeguards in Obtaining Expert Services, but Additional Direction from Congress Is Needed

A letter report issued by the Government Accountability Office with an abstract that begins "The America COMPETES Act gave the National Institute of Standards and Technology (NIST), within the Department of Commerce, the authority, through 2010, to obtain the temporary services of up to 200 experts or consultants per year, but did not specify how the agency should acquire these services. NIST has used this authority to award personal services contracts to obtain the services of individuals. The act requires GAO to report on whether additional safeguards would be needed if NIST's authority were to be made permanent. To meet that requirement, GAO determined (1) the extent to which NIST has used its authority; (2) how effective the authority has been in helping NIST meet its need for experts; and (3) the extent to which NIST has provided appropriate safeguards over its use, and what additional safeguards are needed. GAO reviewed statutes, regulations, federal guidance, and NIST's contracts. In addition, GAO interviewed officials at NIST, Commerce, and the Office of Personnel Management (OPM)."

DOD Business Systems Modernization: Key Navy Programs' Compliance with DOD's Federated Business Enterprise Architecture Needs to Be Adequately Demonstrated

A letter report issued by the Government Accountability Office with an abstract that begins "For decades, the Department of Defense (DOD) has been challenged in modernizing its thousands of business systems. Since 1995, GAO has designated the department's business systems modernization efforts as high risk. One key to effectively modernizing DOD's systems environment and satisfying relevant legislative requirements is ensuring that business system investments comply with an enterprisewide strategic blueprint, commonly called an enterprise architecture. For DOD's business systems modernization, it is developing and using a federated Business Enterprise Architecture (BEA), which is a coherent family of parent and subsidiary architectures. GAO was requested to determine whether key Department of the Navy business systems modernization programs comply with DOD's federated BEA. To determine this, GAO examined the BEA compliance assessments, certifications, and approvals for selected Navy programs against relevant guidance."

Defense Acquisitions: Actions to Improve Navy SPAWAR Low-Rate Initial Production Decisions

A letter report issued by the General Accounting Office with an abstract that begins "During its review of the Navy's Space and Naval Warfare (SPAWAR) Systems Command's fiscal year 2001 budget request, GAO found that many information technology systems were being procured and fielded in relatively large quantities--sometimes exceeding 50 percent of the total--during low-rate initial production and before completion of operational testing. The primary purpose of low-rate initial production is to produce enough units for operational testing and evaluation and to establish production capabilities to prepare for full-rate production. Commercial and Department of Defense (DOD) best practices have shown that completing a system's testing before producing significant quantities substantially lowers the risk of costly fixes and retrofits. For major weapons systems, statutory provisions limit the quantities of systems produced during low-rate initial production to the minimum quantity necessary. These statutory provisions also require justification for quantities exceeding 10 percent of total production. Although these provisions do not apply to non-major systems, DOD and Navy acquisition regulations encourage these programs to make use of the low-rate initial production concept. This report reviews (1) information systems being procured and fielded for SPAWAR in large numbers before operational testing, (2) what effects …

District of Columbia: More Details Needed on Plans to Integrate Computer Systems With the Family Court and Use Federal Funds

A letter report issued by the General Accounting Office with an abstract that begins "Congress passed the D.C. Family Court Act of 2001 to reform court practices and establish procedures to improve interactions between the District of Columbia's Family Court, of D.C. Superior Court, and social service agencies in the District. The act directed the Mayor to prepare a plan to integrate the computer systems of District agencies with those of the Court. The fiscal year 2002 D.C. Appropriations Act authorized $200,000 for integrating the computer systems and $500,000 for social workers to implement family court reform.

Food and Drug Administration: Approval and Oversight of the Drug Mifeprex (open access)

Food and Drug Administration: Approval and Oversight of the Drug Mifeprex

A letter report issued by the Government Accountability Office with an abstract that begins "In September 2000, the Food and Drug Administration (FDA), part of the Department of Health and Human Services (HHS), approved the drug Mifeprex for use in terminating early term pregnancy. FDA approved the drug under a provision of its Subpart H regulations, allowing it to restrict the drug's distribution to assure its safe use. Critics have questioned aspects of the Mifeprex approval process, including the reliance on historically-controlled clinical trials that compare a drug's effects on a condition to the known course of the condition rather than to another drug or placebo. Critics argued that Mifeprex does not fit within the scope of Subpart H, which applies to drugs that treat serious or life-threatening illnesses. Concerns have also been raised about FDA's oversight of the drug since approval, including the agency's response to deaths in U.S. women who had taken the drug. In this report GAO (1) describes FDA's approval of Mifeprex, including the evidence considered and the restrictions placed on its distribution; (2) compares the Mifeprex approval process to the approval processes for other Subpart H restricted drugs; and (3) compares FDA's postmarket oversight of …

SERDP ER-1376 Enhancement of In Situ Bioremediation of Energetic Compounds by Coupled Abiotic/Biotic Processes:Final Report for 2004 - 2006 (open access)

SERDP ER-1376 Enhancement of In Situ Bioremediation of Energetic Compounds by Coupled Abiotic/Biotic Processes:Final Report for 2004 - 2006

This project was initiated by SERDP to quantify processes and determine the effectiveness of abiotic/biotic mineralization of energetics (RDX, HMX, TNT) in aquifer sediments by combinations of biostimulation (carbon, trace nutrient additions) and chemical reduction of sediment to create a reducing environment. Initially it was hypothesized that a balance of chemical reduction of sediment and biostimulation would increase the RDX, HMX, and TNT mineralization rate significantly (by a combination of abiotic and biotic processes) so that this abiotic/biotic treatment may be a more efficient for remediation than biotic treatment alone in some cases. Because both abiotic and biotic processes are involved in energetic mineralization in sediments, it was further hypothesized that consideration for both abiotic reduction and microbial growth was need to optimize the sediment system for the most rapid mineralization rate. Results show that there are separate optimal abiotic/biostimulation aquifer sediment treatments for RDX/HMX and for TNT. Optimal sediment treatment for RDX and HMX (which have chemical similarities and similar degradation pathways) is mainly chemical reduction of sediment, which increased the RDX/HMX mineralization rate 100 to150 times (relative to untreated sediment), with additional carbon or trace nutrient addition, which increased the RDX/HMX mineralization rate an additional 3 to 4 …

PION SCATTERING FROM A POLARIZED TARGET

This report describes the use of a target containing polarized protons in a particle-scattering experiment. Positive pions of 246-MeV kinetic energy were scattered from the polarized protons. The parameter P that was measured is equivalent to that determined by analyzing the recoil-proton polarization in scattering from an unpolarized target. It has been measured to a higher accuracy than heretofore achieved in pion-proton scattering, at an energy and at angles inconvenient for double-scattering techniques.

Oxygen Transport Ceramic Membranes

In the present quarter, experiments are presented on ceramic/metal interactions of Zirconia/ Ni-B-Si system and with a thin Ti coating deposited on zirconia surface. Existing facilities were modified for evaluation of environmental assisted slow crack growth and creep in flexural mode. Processing of perovskites of LSC, LSF and LSCF composition were continued for evaluation of mechanical properties as a function of environment. These studies in parallel to those on the LSFCO composition is expect to yield important information on questions such as the role of cation segregation and the stability of the perovskite structure on crack initiation vs. crack growth. Studies have been continued on the La{sub 1-x}Sr{sub x}FeO{sub 3-d} composition using neutron diffraction and TGA studies. A transition from p-type to n-type of conductor was observed at relative low pO{sub 2}, at which the majority carriers changed from the holes to electrons because of the valence state decreases in Fe due to the further loss of oxygen. Investigation on the thermodynamic properties of the membrane materials are continued to develop a complete model for the membrane transport. Data obtained at 850 C show that the stoichiometry in La{sub 0.2}Sr{sub 0.8}Fe{sub 0.8}Cr{sub 0.2}O{sub 3-x} vary from {approx}2.85 to 2.6 over …

Temporal Representation in Semantic Graphs

A wide range of knowledge discovery and analysis applications, ranging from business to biological, make use of semantic graphs when modeling relationships and concepts. Most of the semantic graphs used in these applications are assumed to be static pieces of information, meaning temporal evolution of concepts and relationships are not taken into account. Guided by the need for more advanced semantic graph queries involving temporal concepts, this paper surveys the existing work involving temporal representations in semantic graphs.

The 126-B-3 waste site is the former coal storage pit for the 184-B Powerhouse. During demolition operations in the 1970s, the site was used for disposal of demolition debris from 100-B/C Area facilities. The site has been remediated by removing debris and contaminated soils. The results of verification sampling demonstrated that residual contaminant concentrations do not preclude any future uses and allow for unrestricted use of shallow zone soils. The results also showed that residual contaminant concentrations are protective of groundwater and the Columbia River.

National Certification Methodology for the Nuclear Weapons Stockpile (open access)

National Certification Methodology for the Nuclear Weapons Stockpile

Lawrence Livermore and Los Alamos National Laboratories have developed a common framework and key elements of a national certification methodology called Quantification of Margins and Uncertainties (QMU). A spectrum from senior managers to weapons designers has been engaged in this activity at the two laboratories for on the order of a year to codify this methodology in an overarching and integrated paper. Following is the certification paper that has evolved. In the process of writing this paper, an important outcome has been the realization that a joint Livermore/Los Alamos workshop on QMU, focusing on clearly identifying and quantifying differences between approaches between the two labs plus developing an even stronger technical foundation on methodology, will be valuable. Later in FY03, such a joint laboratory workshop will be held. One of the outcomes of this workshop will be a new version of this certification paper. A comprehensive approach to certification must include specification of problem scope, development of system baseline models, formulation of standards of performance assessment, and effective procedures for peer review and documentation. This document concentrates on the assessment and peer review aspects of the problem. In addressing these points, a central role is played by a 'watch list' …
