A letter report issued by the Government Accountability Office with an abstract that begins "Since 1998, GAO has issued numerous reports on nursing home quality and safety that identified significant weaknesses in federal and state oversight. Under contract with the Centers for Medicare & Medicaid Services (CMS), states conduct annual nursing home inspections, known as surveys, to assess compliance with federal quality and safety requirements. States also investigate complaints filed by family members or others in between annual surveys. When state surveys find serious deficiencies, CMS may impose sanctions to encourage compliance with federal requirements. GAO was asked to assess CMS's progress since 1998 in addressing oversight weaknesses. GAO (1) reviewed the trends in nursing home quality from 1999 through January 2005, (2) evaluated the extent to which CMS's initiatives have addressed survey and oversight problems identified by GAO and CMS, and (3) identified key challenges to continued progress in ensuring resident health and safety. GAO reviewed federal data on the results of state nursing home surveys and federal surveys assessing state performance; conducted additional analyses in five states with large numbers of nursing homes; reviewed the status of its prior recommendations; and identified key workforce and workload issues confronting …

A letter report issued by the Government Accountability Office with an abstract that begins "The Legal Services Corporation (LSC) was created as a private nonprofit to support legal assistance for low-income people to resolve their civil legal matters and relies heavily on federal appropriations. In 2006, LSC distributed most of its $327 million in grants to support such assistance. Effective internal controls over grants and oversight of grantees are critical to LSC's mission. GAO was asked to determine whether LSC's internal controls over grants management and oversight processes provide reasonable assurance that grant funds are used for their intended purposes. GAO analyzed key records and interviewed agency officials to obtain an understanding of LSC's internal control framework, including the monitoring and oversight of grantees, and performed limited reviews of internal controls and compliance at 14 grantees."

A letter report issued by the Government Accountability Office with an abstract that begins "Disputes between policyholders and insurers after the 2005 hurricane season highlight the challenges in understanding the cause and extent of damages when properties are subjected to both high winds and flooding. Questions remain over the adequacy of steps taken by the Federal Emergency Management Agency (FEMA) to ensure that claims paid by the National Flood Insurance Program (NFIP) cover only those damages caused by flooding. GAO was asked to evaluate (1) issues that arise when multiple insurance policies provide coverage for losses from a single event, (2) state regulators' oversight of loss adjusters, and (3) information that NFIP collects to assess the accuracy of damage determinations and payments. GAO collected data from FEMA, reviewed reinspection reports and relevant policies and procedures, and interviewed state regulatory officials and others about adjuster oversight and NFIP."

A letter report issued by the General Accounting Office with an abstract that begins "In September 2000, the U.S. Census Bureau told Congress that it had at least $305 million in budget savings out of its $4.5 billion fiscal year 2000 no-year appropriations for the 2000 decennial census. Of the $4.5 billion appropriated to the U.S. Census Bureau in fiscal year 2000, lower-than-expected expenditures and obligations resulted in available balances of at least $415 million. A lower-than-expected support staff workload reduced salary and benefit costs by about $348 million. Enumerator workload is largely determined by the initial mail response rate for returned census questionnaires. The initial mail response of 64 percent meant that Census enumerators did not have to visit more than three million American households. However, the available balances from the higher mail response rate and the lower support staff workload were partially offset by about $100 million of higher salary and benefit costs for enumerators, including a higher workload for unanticipated recounts. According to Bureau data, enumerator productivity did not significantly affect budget variances for the 2000 decennial census. The Bureau reported the national average time to visit a household and complete a census questionnaire was about the …

A letter report issued by the General Accounting Office with an abstract that begins "Section 212 of the Small Business Regulatory Enforcement Fairness Act requires agencies to publish compliance guides for each rule or group of related rules for which the agency is required to prepare a final regulatory flexibility analysis. GAO found that Section 212 has had little impact, and its implementation has varied across and sometimes within the agencies. None of the agencies in GAO's review provided GAO with guidance documents that met all of the statutory requirements for all of their 1999 and 2000 final rules. The agencies indicated that they tried to put their compliance guides in plain language--just as they have for all their regulatory materials. The guidance documents that the agencies gave GAO were often published on the agencies' web sites. Direct mail, electronic list servers, agency/regional offices, and workshops were also used for distribution."

A letter report issued by the Government Accountability Office with an abstract that begins "Medicare cost plans--managed care plans paid based on the reasonable costs of delivering Medicare-covered services--enroll a small number of beneficiaries compared to Medicare Advantage (MA), Medicare's managed care program in which the plans accept financial risk if their costs exceed fixed payments received for each enrolled beneficiary. Despite the small enrollment, industry representatives stated that cost plans provide a managed care option in areas that traditionally had few or no MA plans. Current law allows existing cost plans to continue operating unless specific MA plans of sufficient enrollment serve the same area. In such cases, the cost plan must discontinue serving that area beginning in 2011. The Medicare Improvements for Patients and Providers Act of 2008 (MIPPA) required the Government Accountability Office (GAO) to examine issues related to the conversion of Medicare cost plans to MA plans. In response, GAO (1) determined the MA options available to beneficiaries in cost plans, (2) described key differences for beneficiaries between cost plans, MA plans, and Medicare fee-for-service (FFS); (3) determined the extent to which organizations offering cost plans also offer MA plans; and (4) described concerns cost plans …

A Discontinuous Galerkin method for solving hyperbolic systems of conservation laws involving interfaces is presented. The interfaces are represented by a collection of element boundaries and their position is updated using an arbitrary Lagrangian-Eulerian method. The motion of the interfaces and the numerical fluxes are obtained by solving a Riemann problem. As the interface is propagated, a simple and effective remeshing technique based on distance functions regenerates the grid to preserve its quality. Compared to other interface capturing techniques, the proposed approach avoids smearing of the jumps across the interface which leads to an improvement in accuracy. Numerical results are presented for several typical two-dimensional interface problems, including flows with surface tension.

The mean cost for converging an estimated density of states using the Wang-Landau algorithm is measured for the Ising and Heisenberg models. The cost increases in a power-law fashion with the number of spins, with an exponent near 3 for one-dimensional models, and closer to 2.4 for two-dimensional models. The effect of multiple, simultaneous walkers on the cost is also measured. For the one-dimensional Ising model the cost can increase with the number of walkers for large systems. For both the Ising and Heisenberg models in two-dimensions, no adverse impact on the cost is observed. Thus multiple walkers is a strategy that should scale well in a parallel computing environment for many models of magnetic materials.

Gas Technology Institute (GTI), together with Hamworthy Peabody Combustion Incorporated (formerly Peabody Engineering Corporation), the University of Utah, and Far West Electrochemical have developed and demonstrated an innovative combustion system suitable for natural gas and coke-oven gas firing within the steel industry. The combustion system is a simple, low-cost, energy-efficient burner that can reduce NOx by more than 75%. The U.S. steel industry needs to address NOx control at its steelmaking facilities. A significant part of NOx emissions comes from gas-fired boilers. In steel plants, byproduct gases – blast furnace gas (BFG) and coke-oven gas (COG) – are widely used together with natural gas to fire furnaces and boilers. In steel plants, natural gas can be fired together with BFG and COG, but, typically, the addition of natural gas raises NOx emissions, which can already be high because of residual fuel-bound nitrogen in COG. The Project Team has applied its expertise in low-NOx burners to lower NOx levels for these applications by combining advanced burner geometry and combustion staging with control strategies tailored to mixtures of natural gas and byproduct fuel gases. These methods reduce all varieties of NOx – thermal NOx produced by high flame temperatures, prompt NOx produced …

We report a passively mode-locked fiber-based oscillator that has no internal dispersion-compensating gratings. This design, the first of its kind, produces 25 nJ pulses at 80 MHz with the pulses compressible to 150 fs. The pulses appear to be self-similar and initial data imply that their energy is further scalable.

A dielectric barrier discharge (DBD) technique has been employed to produce uniform atmospheric plasmas of He and N2 gas mixtures in open air in order to functionalize the surface of filtered-arc deposited hydrogen-free diamond-like carbon (DLC) films. XPS measurements were carried out on both untreated and He/N2 DBD plasma treated DLC surfaces. Chemical states of the C 1s and N 1s peaks were collected and used to characterize the surface bonds. Contact angle measurements were also used to record the short- and long-term variations in wettability of treated and untreated DLC. In addition, cell viability tests were performed to determine the influence of various He/N2 atmospheric plasma treatments on the attachment of osteoblast MC3T3 cells. Current evidence shows the feasibility of atmospheric plasmas in producing long-lasting variations in the surface bonding and surface energy of hydrogen-free DLC and consequently the potential for this technique in the functionalization of DLC coated devices.

Decades of underground coal mining has left about 5,000 square miles of abandoned mine workings that are rapidly filling with water. The water quality of mine pools is often poor; environmental regulatory agencies are concerned because water from mine pools could contaminate diminishing surface and groundwater supplies. Mine pools are also a threat to the safety of current mining operations. Conversely, mine pools are a large, untapped water resource that, with treatment, could be used for a variety of industrial purposes. Others have proposed using mine pools in conjunction with heat pumps as a source of heating and cooling for large industrial facilities. The management or use of mine pool water requires accurate maps of mine pools. West Virginia University has predicted the likely location and volume of mine pools in the Pittsburgh Coalbed using existing mine maps, structure contour maps, and measured mine pool elevations. Unfortunately, mine maps only reflect conditions at the time of mining, are not available for all mines, and do not always denote the maximum extent of mining. Since 1999, the National Energy Technology Laboratory (NETL) has been evaluating helicopter-borne, electromagnetic sensing technologies for the detection and mapping of mine pools. Frequency domain electromagnetic sensors …

Composition projections for Sludge Batch 5 (SB5) were developed, based on a modeling approach at the Savannah River National Laboratory (SRNL), to evaluate possible impacts of the Al-dissolution process on the availability of viable frit compositions for vitrification at the Defense Waste Processing Facility (DWPF). The study included two projected SB5 compositions that bound potential outcomes (or degrees of effectiveness) of the Al-dissolution process, as well as a nominal SB5 composition projection based on the results of the recent Al-dissolution demonstration at SRNL. The three SB5 projections were the focus of a two-stage paper study assessment. A Nominal Stage assessment combined each of the SB5 composition projections with an array of 19,305 frit compositions over a wide range of waste loading (WL) values and evaluated them against the DWPF process control models. The Nominal Stage results allowed for the down-selection of a small number of frits that provided reasonable projected operating windows (typically 27 to 42 wt% WL). The frit/sludge systems were mostly limited by process related constraints, with only one system being limited by predictions of nepheline crystallization, a waste form affecting constraint. The criteria applied in selecting the frit compositions somewhat restricted the compositional flexibility of the candidate …

In the event of a toxic chemical release to the atmosphere, shelter-in-place (SIP) is an emergency response option available to protect public health. This paper is the last in a three-part series that examines the effectiveness of SIP at reducing adverse health effects in communities. We model a hypothetical chemical release in an urban area, and consider SIP effectiveness in protecting occupants of commercial buildings. Building air infiltration rates are predicted from empirical data using an existing model. We consider the distribution of building air infiltration rates both with mechanical ventilation systems turned off and with the systems operating. We also consider the effects of chemical sorption to indoor surfaces and nonlinear chemical dose-response relationships. We find that commercial buildings provide effective shelter when ventilation systems are off, but that any delay in turning off ventilation systems can greatly reduce SIP effectiveness. Using a two-zone model, we find that there can be substantial benefit by taking shelter in the inner parts of a building that do not experience direct air exchange with the outdoors. Air infiltration rates vary substantially among buildings and this variation is important in quantifying effectiveness for emergency response. Community-wide health metrics, introduced in the previous papers …
