A letter report issued by the Government Accountability Office with an abstract that begins "The safety of the nation's flying public depends, in large part, on the aviation industry's compliance with safety regulations and the Federal Aviation Administration's (FAA) enforcement of those regulations when violations occur. FAA attempts to gain the industry's compliance through enforcement tools, including levying fines and suspending or revoking operating certificates, and partnership programs that allow participating companies or individuals to self-report violations of safety regulations and mitigate or avoid fines or other legal actions. GAO was asked to assess how FAA uses its enforcement options to address noncompliance and what management controls are in place to ensure that enforcement efforts and partnership programs result in compliance with aviation safety regulations."

Testimony issued by the Government Accountability Office with an abstract that begins "GAO summarized the results of its investigation, performed at Congress' request, of street narcotic sales in the vicinity of certain drug rehabilitation clinics in the District of Colombia. To obtain an overview of the problem, we conducted physical surveillance of five clinics in the District of Columbia and interviewed clinic personnel and law enforcement officials. In brief, we found that a significant amount of illegal drug trafficking activity takes place around these clinics. Patients frequently must navigate their way through a virtual bazaar of illegal drug dealing when they enter and exit the facilities."

This report discusses the social security benefits and the spousal benefits of individuals who are not financially dependent on their spouses because they receive benefits based on their own work records.

One problem which plagues the numerical evaluation of one-loop Feynman diagrams using recursive integration by part relations is a numerical instability near exceptional momentum configurations. In this contribution we will discuss a generic solution to this problem. As an example we consider the case of forward light-by-light scattering.

The TNX pilot-scale research facility released processed waste, containing elevated concentrations of several metals and radionuclides into an unlined seepage basin between 1958 and 1980. The contents of this basin have entered the nearby swamp, the TNX Outfall Delta (TNX OD), by subsurface and overland flow. Studies were conducted to evaluate whether sediment amendments could be used to reduce contaminant mobility and bioavailability. Previous studies showed that the addition of a phosphate mineral, apatite, and zero-valent iron, Fe(0), were effective at immobilizing a broad range of contaminants at the site. It is anticipated that the sediment amendments will be broadcast on the ground surface and backfilled into drilled 2 cm diameter x 15 cm deep holes spaced across the contaminated area. The amendments' zone-of-influence of these two application methods was conducted to permit treatment design. The objective of this study was to determine (1) which source of phosphate mineral is most suitable for sediment-contaminant stabilization, and (2) what is the extent of the zone-of-influence of applied apatite and Fe(0).

Effects of MHD reconnection events on the beam-plasma fusion reactivity and transport of the beam ions are studied. Based on the analysis of fusion reactivity changes induced by MHD events, the conclusion is drawn that the strong drops of the neutron yield during sawtooth crashes observed in the National Spherical Torus experiment (NSTX) [M. Ono et al., Nucl. Fusion 40, 557 (2000)] are associated with both a particle redistribution inside the plasma and a loss of the beam ions. Mechanisms of the energetic ion transport during sawtooth crashes are analyzed, in particular, with the use of the resonance adiabatic invariant derived in this paper. A numerical simulation of the particle motion during a sawtooth crash in NSTX is done with the code OFSEF [Ya. I. Kolesnichenko, et al., Nucl. Fusion 40, 1325 (2000)] extended for a better description of the particle precession. It is shown that the motion of toroidally passing particles in NSTX can become stochastic under the influence of a crash. This stochasticity, as well as the motion along the resonance island, leads to the escape of some particles from the plasma.

The method of protectively coating metallic uranium which comprises dipping the metallic uranium in a molten alloy comprising about 20-75% of copper and about 80-25% of tin, dipping the coated uranium promptly into molten tin, withdrawing it from the molten tin and removing excess molten metal, thereupon dipping it into a molten metal bath comprising aluminum until it is coated with this metal, then promptly withdrawing it from the bath.

Nevada Underserved Science Education Program (NUSEP) is a project to examine the effect of implementing new and innovative Earth and space science education curriculum in Nevada schools. The project provided professional development opportunities and educational materials for teachers participating in the program.

Age-appropriate technical writing lessons for underperforming high-school students can offer them an innovative, ''authentic'' way to improve how they read and write. Thus the techniques and principles of effective technical communication routinely applied at work also provide a positive response to one of today's great educational challenges. This workshop shows participants how to (1) introduce English and science teachers to the value of technical writing as a response to school literacy problems, (2) prepare plausible practice exercises to help students improve their basic literacy, and (3) recognize and respond to known literacy outreach pitfalls. Every effective literacy outreach project based on technical writing needs to address four key problems.

The global demilitarization of nuclear and conventional munitions is producing millions of pounds of surplus energetic materials. Historically, energetic materials (high explosives, propellants, and pyrotechnics) have been disposed of by open burning/open detonation (OB/OD). The use of OB/OD is becoming unacceptable due to public concerns and increasingly stringent environmental regulations. Clearly, there is a great need to develop environmentally sound and cost-effective alternatives to OB/OD. The conversion of surplus picric acid and/or ammonium picrate (Explosive D) to1,3,5-triamino-2,4,6- trinitrobenzene (TATB) has been subject of extensive process development studies at Lawrence Livermore National Laboratory (LLNL). LLNL, under the direction and sponsorship of the U.S. Army Defense Ammunition Center (DAC), is developing a process for the conversion of picric acid to TATB on a larger scale. In FY 03, a 10 g per batch process was developed with good results. Development for a one pound per batch system is required as part of overall scale up process for producing TATB from the surplus feedstocks.

We are currently developing a plutonium ceramic target for the MASHA mass separator. The MASHA separator will use a thick plutonium ceramic target capable of tolerating temperatures up to 2000 C. Promising candidates for the target include oxides and carbides, although more research into their thermodynamic properties will be required. Reaction products will diffuse out of the target into an ion source, where they will then be transported through the separator to a position-sensitive focal-plane detector array. Experiments on MASHA will allow us to make measurements that will cement our identification of element 114 and provide for future experiments where the chemical properties of the heaviest elements are studied.

The mechanical response of a pearlitic UHCS-1.3C steel deformed at approximately 4000 s{sup -1} to large strains ({var_epsilon} = -0.9) has been studied. Failure, at both the macroscopic and the microscopic levels has been evaluated, and the ability of the material to absorb energy in compression has been examined. Failure occurred by the development of a shear band. However before failure, extensive buckling of the carbide plates was observed and the UHCS-1.3C material exhibited significant potential for compressive ductility and energy absorption due to the distributed buckling of these plates. Strain localization during adiabatic shear band development resulted in the formation of austenite. Subsequent cooling produced a divorced-eutectoid transformation with associated deformation, which resulted in a microstructure consisting of 50 to 100 nm sized grains. The stress-strain behavior within the shear band has also been determined. The results are used to critically evaluate the maximum shear stress criterion of shear band development. New criteria for the development of shear bands are developed based on a strain energy concept.
