Combating Child Pornography: Federal Agencies Coordinate Law Enforcement Efforts, but an Opportunity Exists for Further Enhancement

A letter report issued by the General Accounting Office with an abstract that begins "The trafficking of child pornography through increasingly sophisticated electronic media, including Internet chat rooms, newsgroups, and peer-to-peer networks, has made such images more readily accessible. These technological advances have created more challenges for law enforcement, including requiring effective coordination to combat this crime. The federal law enforcement agencies that play a role in investigating child pornography are the FBI, Customs, Postal Inspection Service, and Secret Service. This report provides information on the coordination of federal efforts to combat child pornography. Specifically, it (1) identifies mechanisms federal agencies have in place to combat child pornography and (2) provides information on an opportunity to further enhance coordination among federal law enforcement agencies."

Combating Terrorism: Intergovernmental Cooperation in the Development of a National Strategy to Enhance State and Local Preparedness

Testimony issued by the General Accounting Office with an abstract that begins "Federal, state, and local governments share responsibility for terrorist attacks. However, local government, including police and fire departments, emergency medical personnel, and public health agencies, is typically the first responder to an incident. The federal government historically has provided leadership, training, and funding assistance. In the aftermath of September 11, for instance, one-quarter of the $40 billion Emergency Response Fund was earmarked for homeland security, including enhancing state and local government preparedness. Because the national security threat is diffuse and the challenge is highly intergovernmental, national policymakers must formulate strategies with a firm understanding of the interests, capacity, and challenges facing those governments. The development of a national strategy will improve national preparedness and enhance partnerships between federal, state, and local governments. The creation of the Office of Homeland Security is an important and potentially significant first step. The Office of Homeland Security's strategic plan should (1) define and clarify the appropriate roles and responsibilities of federal, state, and local entities; (2) establish goals and performance measures to guide the nation's preparedness efforts; and (3) carefully choose the most appropriate tools of government to implement the national strategy …

COMBUSTION TURBINE (CT) HOT SECTION COATING LIFE MANAGEMENT

The integrity of coatings used in hot section components of combustion turbine is crucial to the reliability of the buckets. This project was initiated in recognition of the need for predicting the life of coatings analytically, and non destructively; correspondingly, three principal tasks were established. Task 1, with the objective of analytically developing stress, strain and temperature distributions in the bucket and thereby predicting thermal fatigue (TMF) damage for various operating conditions; Task 2 with the objective of developing eddy current techniques to measure both TMF damage and general degradation of coatings and, Task 3, with the objective of developing mechanism based algorithms. This report is a record of the progress to date on these 3 key tasks. Two supporting tasks relating to field validation (Task 4) and economic analysis (Task 5) have not yet been initiated.

Commercial Aviation: Financial Condition and Industry Responses Affect Competition

Testimony issued by the General Accounting Office with an abstract that begins "This testimony discusses the economic state of the airline industry. Many, but not all, major U.S. passenger airlines are experiencing their second consecutive year of record financial losses. In 2001, the U.S. commercial passenger airline industry reported losses in excess of $6 billion. For 2002, some Wall Street analysts recently projected that U.S. airline industry losses will approach $7 billion, and noted that the prospects for recovery during 2003 are diminishing. Carriers have taken many actions to lower their costs and restructure their operations. Since September 2001, carriers have furloughed 100,000 staff, renegotiated labor contracts, and streamlined their fleets by retiring older, costlier aircraft. Carriers have reduced capacity by operating fewer flights or smaller aircraft. In some cases, carriers eliminated all service to communities. As the aviation industry continues its attempts to recover, Congress will be confronted with a need for increased oversight of a number of public policy issues. First, airlines' reactions to financial pressures will affect the domestic industry's competitive landscape. Second, airlines' reductions in service will likely place additional pressure on federal programs supporting air service to small communities, where travel options are already limited. …

Comparison Between the Predictions and Measurements for the Beam Gas Interactions During the Last Gold and Proton Runs in RHIC.

The last gold-gold and polarized proton-proton collision runs were performed at energies of 100 GeV/nucleon. The beam gas interactions in RHIC are very important for the beam lifetime in RHIC. In this report the lifetime predicted by pressure data differences between the beams ON and beams OFF, at the energies of 100 GeV/nucleon. are compared to the predictions for the beam gas interaction and beam lifetimes.

Computational Chemistry for Nuclear Waste Characterization and Processing: Relativistic Quantum Chemistry of Actinides

In the course of the 3 years we have conducted calculations on molecular structures containing actinides, lanthanides, and other heavy elements. Our calculations were done at the relativistically-correct, all-electron, 4-component calculations (DHF, MP2, and CCSD(T)), using density functional theory (DFT) with relativistic effective core potentials (RECPs), and various other methodologies. We studied the ground- and excited state structures, energetics, vibrational frequencies, and NMR, excitation and ionization spectra. In addition a considerable amount of codes and methodologies have been developed during the GC3 period, enabling us to do the extensive research described in this final report, and providing researchers worldwide with new computational chemistry tools. In this section we will give a brief overview of our activities and accomplishments, grouped by each research institution. A more extensive overview can be found in the appendices containing the full yearly reports.

Construction Site Storm Water Sampling California's New Construction Sampling and Analysis Requirements

The California State Water Resources Control Board (State Board) originally issued a National Pollutant Discharge System (NPDES) permit for storm water discharges associated with construction activities in 1992. This NPDES permit was issued as a general permit, applicable throughout the state (with certain exceptions). The general construction permit was made site-specific by a discharger-developed Storm Water Pollution Prevention Plan (SWPPP). As with most NPDES construction storm water permits, monitoring requirements were limited to inspections. Sampling and analysis of discharges was not specifically required, but a Regional Water Quality Control Board (Regional Board) could require additional monitoring. In 1999, the State -Board revised and reissued its construction general permit. While the 1999 permit significantly enhanced the erosion and sediment control descriptions and requirements, and expanded the inspection program, sampling and analysis was still not required. Environmental advocacy groups took exception to the absence of sampling requirements and sought relief in court to add sampling and analysis. In 2001, the State Board in response to the court order adopted a resolution requiring sampling and analysis of construction site runoff under two conditions. Turbidity and/or sediment sampling is required when construction site runoff enters water bodies determined to impaired for sediment or turbidity. …

Cooling water systems for accelerator components at the Advanced Photon Source.

As in most accelerators at the Advanced Photon Source, water is the media of choice for absorbing heat generated by a multitude of accelerator components. A large cooling water distribution system with flow rate of nearly 10,000 gpm in the primary circuit and small closed-loop water systems with flow rates of less than 100 gpm are installed at the APS. The central plant houses primary water distribution pumps, heat rejection equipment, and polishing and make-up systems. All water used for heat rejection by accelerator equipment is deionized and filtered to provide minimum resistivity of 3 M{Omega}-cm and maximum particle size of 0.5 microns. Water temperature and pressure are being controlled at 35 secondary systems before water is delivered to the accelerator components. Temperature of various water systems is controlled to as tight as + 0.1 deg F. With most accelerator components interlocked on water flow and temperature, it is imperative that both are maintained with a high degree of reliability. It is also necessary for water systems to be designed with sufficient flexibility to allow for easy modifications, additions, and expansions. From the time original water systems were installed a number of system upgrades to improve reliability and to integrate …

Cooperative Threat Reduction Program Annual Report

Correspondence issued by the General Accounting Office with an abstract that begins "Section 1308 of the National Defense Authorization Act for Fiscal Year 2001 requires the Comptroller General to provide Congress with an assessment of the Department of Defense's annual report on the Cooperative Threat Reduction (CTR) program within 90 days of the submission of the annual report to Congress. The Department of Defense submitted its CTR annual report for Fiscal Year 2002 to Congress on September 3, 2002 almost 19 months after the submission date mandated by law. GAO found that the report (1) did not clearly set forth future funding data required by Congress, (2) did not include certain important planning elements, (3) in some instances asserted the use of a more rigorous methodology than was actually used, and (4) incorporated some but not all prior GAO recommendations."

Coupling Measurement and Correction at Rhic.

Coupling correction at RHIC has been operationally achieved through a two-step process: using local triplet skew quadrupoles to compensate coupling corn rolled low-beta triplet quadrupoles, and minimizing the tune separation and residual coupling with orthogonal global skew quadrupole families. An application has been developed for global correction that allows skew quadrupole tuning and tune display with a choice of different tune measurement techniques, including tune-meter, Schottky and phase lock loop (PLL). Coupling effects have been analysed by using 1024-turn (TBT) information from the beam position monitor (BPM) system. These data allow the reconstruction of the off-diagonal terms of the transfer matrix, a measure of global coupling. At both injection and storage energies, coordination of tune meter kicks with TBT acquisition at 322 BPM's in each ring allows the measurement of local coupling at all BPM locations.

Crystal Collimation at Rhic.

For the year 2001 run, a bent crystal was installed in the yellow ring of the Relativistic Heavy Ion Collider (RHIC). The crystal forms the first stage of a two stage collimation system. By aligning the crystal to the beam, halo particles are channeled through the crystal and deflected into a copper scraper. The purpose is to reduce beam halo with greater efficiency than with a scraper alone. In this paper we present the first results from the use of the crystal collimator. We compare the crystal performance under various conditions, such as different particle species, and beta functions.
