A letter report issued by the General Accounting Office with an abstract that begins "The Department of Defense (DOD) maintains equipment and infrastructure worth billions of dollars in many environments where corrosion is causing military assets to deteriorate, shortening their useful life. The resulting increase in required repairs and replacements drives up costs and takes critical systems out of action, reducing mission readiness. GAO was asked to review military activities related to corrosion control. Specifically, this report examines the extent of the impact of corrosion on DOD and the military services and the extent of the effectiveness of DOD's and the services' approach to preventing and mitigating corrosion."

A letter report issued by the General Accounting Office with an abstract that begins "The Army's five maintenance depots produced work valued at $1.5 billion in fiscal year 2002, with the remaining 49 percent of the Army's depot work performed by contractors. GAO was asked to assess (1) the trends in and the reliability of depot workload projections; (2) whether workloads are sufficient for efficient depot operations, initiatives are under way to improve efficiency, and additional workloads are possible; (3) whether the Army has identified depots' core capability and provided workload to support that capability; and (4) whether the Army has a long-range plan for a viable, efficient depot system."

This report documents the results of Phase 1 of the ''Air Force Hydrazine Detector Characterization and Calibration Project''. A method for calibrating model MDA 7100 hydrazine detectors in the United States Air Force (AF) inventory has been developed. The calibration system consists of a Kintek 491 reference gas generation system, a humidifier/mixer system which combines the dry reference hydrazine gas with humidified diluent or carrier gas to generate the required humidified reference for calibrations, and a gas sampling interface. The Kintek reference gas generation system itself is periodically calibrated using an ORNL-constructed coulometric titration system to verify the hydrazine concentration of the sample atmosphere in the interface module. The Kintek reference gas is then used to calibrate the hydrazine monitors. Thus, coulometric titration is only used to periodically assess the performance of the Kintek reference gas generation system, and is not required for hydrazine monitor calibrations. One advantage of using coulometric titration for verifying the concentration of the reference gas is that it is a primary standard (if used for simple solutions), thereby guaranteeing, in principle, that measurements will be traceable to SI units (i.e., to the mole). The effect of humidity of the reference gas was characterized by using …

An experimental technique is presented that permits diagnostics viewing light from the plasma edge to be spatially calibrated relative to one another. By sweeping the plasma edge, each chord of each diagnostic sweeps out a portion of the light emission profile. A nonlinear least-squares fit to such data provides superior cross-calibration of diagnostics located at different toroidal locations compared with simple surveying. Another advantage of the technique is that it can be used to monitor the position of viewing chords during an experimental campaign to ensure that alignment does not change over time. Moreover, should such a change occur, the data can still be cross-calibrated and its usefulness retained.

Recent experimental observations from NSTX [National Spherical Torus Experiment] suggest that many modes in a subcyclotron frequency range are excited during neutral-beam injection (NBI). These modes have been identified as Compressional Alfven Eigenmodes (CAEs) and Global Alfven Eigenmodes (GAEs), which are driven unstable through the Doppler-shifted cyclotron resonance with the beam ions. The injection velocities of the NBI ions in NSTX are large compared to Alfven velocity, V(sub)0 > 3V(sub)A, and a strong anisotropy in the fast-ion pitch-angle distribution provides the energy source for the instabilities. Recent interest in the excitation of Alfven Eigenmodes in the frequency range omega less than or approximately equal to omega(sub)ci, where omega(sub)ci is the ion cyclotron frequency, is related to the possibility that these modes can provide a mechanism for direct energy transfer from super-Alfvenic beam ions to thermal ions. Numerical simulations are required in order to find a self-consistent mode structure, and to include the effects of finite-Larmor radius (FLR), the nonlinear effects, and the thermal plasma kinetic effects.

The neutralization of solutions containing significant quantities of fissile material at the Department of Energy's Savannah River Site and the subsequent transfer of the slurry to the High Level Waste (HLW) system is accomplished with the addition of a neutron poison to ensure nuclear safety. Gd, depleted U, Fe, and Mn have been used as poisons in the caustic precipitation of process solutions prior to discarding to HLW. However, the use of Gd is preferred since only small amounts of Gd are necessary for effective criticality control, smaller volumes of metal hydroxides are produced, and the volume of HLW glass resulting from this process is minimized.

The multilevel physics, massively parallel plasma simulation code, M3D, has been used to study spherical tori (STs) and tokamaks. The magnitude of outboard shift of density profiles relative to electron temperature profiles seen in NSTX [National Spherical Torus Experiment] under strong toroidal flow is explained. Internal reconnection events in ST discharges can be classified depending on the crash mechanism, just as in tokamak discharges; a sawtooth crash, disruption due to stochasticity, or high-beta disruption. Toroidal shear flow can reduce linear growth of internal kink. It has a strong stabilizing effect nonlinearly and causes mode saturation if its profile is maintained, e.g., through a fast momentum source. Normally, however, the flow profile itself flattens during the reconnection process, allowing a complete reconnection to occur. In some cases, the maximum density and pressure spontaneously occur inside the island and cause mode saturation. Gyrokinetic hot particle/MHD hybrid studies of NSTX show the effects of fluid compression on a fast-ion-driven n = 1 mode. MHD studies of recent tokamak experiments with a central current hole indicate that the current clamping is due to sawtooth-like crashes, but with n = 0.

An estimated 41.2 million people were without health insurance in 2001. Legislation under consideration by the 108th and earlier Congresses is intended to assist small employers in offering health insurance as a benefit to their workers. A new bill, H.R. 4281, introduced on May 5, 2004, The Small Business Health Fairness Act of 2003 (H.R. 6601s. 545), and a number of bills from the earlier Congresses include provisions creating new groups for small firms to join or encouraging the growth of existing groups so that small employers can band together to offer coverage to their employees.

Under the federal system in the United States, the states and localities traditionally have held the major responsibility for prevention and control of crime and maintenance of order. For most of the Republic’s history, “police powers” in the broad sense were reserved to the states under the Tenth Amendment to the Constitution. Many still hold that view, but others see a string of court decisions in recent decades as providing the basis for a far more active federal role. Several bills are discussed in this report that address issues related to crime, juvenile justice, and Congress’ evolving role in crime legislation.

The Superfund program for cleaning up the nation’s worst hazardous waste sites was created by the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, or CERCLA (P.L. 96-510, as amended). This report discusses recent development and background issues, superfund issues, revenue issues, comprehensive reauthorization, and legislation regarding superfund program.

The United States accords permanent normal-trade-relations (NTR) (formerly called most-favored-nation (MFN)) treatment to all its trading partners except six countries to which it is denied by law and 11 countries whose NTR status is temporary and subject to the conditions of Title IV of the Trade Act of 1974.

In the 108th Congress, debate over energy efficiency programs has focused on budget, oil, natural gas, and electricity issues, and provisions in the omnibus energy policy bill, S. 2095, H.R. 6, and S. 14/S. 1149. The Bush Administration’s FY2005 budget request for the Department of Energy’s (DOE’s) Energy Efficiency Program sought $875.9 million, including $543.9 for R&D and $332.0 million for grants. In the first session, the omnibus energy bill (H.R. 6) had several significant tax and regulatory measures for energy efficiency. It did not pass the Senate due to concerns about cost and an MTBE “safe harbor” provision.

China’s economy continues to be a concern to U.S. policymakers. On the one hand, China’s economic growth presents huge opportunities for U.S. exporters. On the other hand, the surge in Chinese exports to the United States has put competitive pressures on many U.S. industries. Many U.S. policymakers have argued that greater efforts should be made to pressure China to fully implement its WTO commitments and to change various economic policies deemed harmful to U.S. economic interests, such as its currency peg and its use of subsidies to support its SOEs. In addition, recent bids by Chinese state-owned firms to purchase various U.S. firms have raised concerns among Members over the impact such acquisitions could have on U.S. national and economic security.
