A letter report issued by the Government Accountability Office with an abstract that begins "Medicaid, a federal-state program that finances health care for certain low-income populations, can play a critical role in the provision of preventive services, which help prevent, diagnose, and manage health conditions. GAO examined available data to assess (1) the extent to which Medicaid children and adults have certain health conditions and receive certain preventive services, (2) for Medicaid children, state monitoring and promotion of the provision of preventive services, (3) for Medicaid adults, state coverage of preventive services, and (4) federal oversight by the Centers for Medicare & Medicaid Services (CMS). GAO analyzed data from nationally representative surveys: the National Health and Nutrition Examination Survey (NHANES), which includes physical examinations of participants, and the Medical Expenditure Panel Survey (MEPS). GAO also surveyed state Medicaid directors and interviewed federal officials."

In each case, the information was supplied by the agency itself and is current as of the date of publication. Entries are arranged alphabetically in four sections: legislative branch; judicial branch; executive branch; and agencies, boards, and commissions.

A letter report issued by the Government Accountability Office with an abstract that begins "In fiscal year 2008, the Department of Education (Education) oversaw the distribution of approximately $96 billion in federal student financial aid, including $14.6 billion in Pell Grants to low- and middle-income students, to help students and their families pay for higher-education expenses. Much of this aid was distributed based on a formula specified in the Higher Education Act, as amended, that is used to identify students who need financial assistance to pay for higher education. To apply for federal financial aid, such as Pell Grants, students submit a Free Application for Federal Student Aid on which they report their own or both their own and their families' income and assets. Students who are financially dependent on their parents or other family members are required to report their own and their family's income and assets, while those who are financially independent report only their own income and assets (and their spouse's, if they are married). To determine if a student has financial need, the aid formula compares how much it costs a student to attend a particular college and an estimate of how much the student or …

A letter report issued by the Government Accountability Office with an abstract that begins "Companies that develop and produce oil and gas from federal lands and waters are required to report their production volumes and other data to the Department of the Interior's (Interior) Minerals Management Service (MMS) and to pay royalties either in value (cash) or in kind (oil or gas). In fiscal year 2008, MMS estimated that it had collected more than $2.4 billion in royalty-in-kind (RIK) gas. It is important that MMS ensure that it receives the RIK gas to which it is entitled. The difference between the RIK gas owed--MMS's entitled percentage of gas--and the percentage it actually receives is referred to as a "gas imbalance." GAO was asked to evaluate the extent to which MMS can provide reasonable assurance that it is accurately identifying and collecting RIK gas imbalances in a timely fashion. GAO analyzed MMS documents and data, documentation of industry standards, and interviewed MMS and industry officials."

A letter report issued by the Government Accountability Office with an abstract that begins "The growing volume of consumer products imported into the United States has strained the resources of the Consumer Product Safety Commission (CPSC), challenging the agency to find new ways to ensure the safety of these products. The Consumer Product Safety Improvement Act (CPSIA) mandated that GAO assess the effectiveness of CPSC's authorities over imported products. GAO's objectives were to (1) determine what is known about CPSC's effectiveness in using these authorities, (2) compare CPSC's authorities with those of selected U.S. agencies and international entities, and (3) evaluate CPSC's plans to prevent the entry of unsafe consumer products. To address these objectives, GAO analyzed CPSC and other agencies' and entities' authorities, reviewed literature on consumer product safety, and compared CPSC's planning efforts with criteria for effective planning practices."

Simulations of the x-ray free-electron laser (FEL) oscillator are presented that include transverse effects and realistic Bragg crystal properties with the two-dimensional code GINGER. In the present cases considered the radiation divergence is much narrower than the crystal acceptance, and the numerical algorithm can be simplified by ignoring the finite angular bandwidth of the crystal. In this regime GINGER shows that the saturated x-ray pulses have 109 photons and are nearly Fourier-limited with peak powers in excess of 1 MW. Wealso include preliminary results for a four-mirror cavity that can be tuned in wavelength over a few percent, with future plans to incorporate the full transverse response of the Bragg crystals into GINGER to more accurately model this tunable source.

Pacific Northwest National Laboratory (PNNL) has been tasked by Bechtel National Inc. (BNI) on the River Protection Project-Hanford Tank Waste Treatment and Immobilization Plant (RPP-WTP) project to perform research and development activities to resolve technical issues identified for the Pretreatment Facility (PTF). The Pretreatment Engineering Platform (PEP) was designed and constructed and is to be operated as part of a plan to respond to issue M12, “Undemonstrated Leaching Processes.” The PEP is a 1/4.5-scale test platform designed to simulate the WTP pretreatment caustic leaching, oxidative leaching, ultrafiltration solids concentration, and slurry washing processes. The PEP replicates the WTP leaching processes using prototypic equipment and control strategies. The PEP also includes non-prototypic ancillary equipment to support the core processing. Two operating scenarios are currently being evaluated for the ultrafiltration process (UFP) and leaching operations. The first scenario has caustic leaching performed in the UFP-2 ultrafiltration feed vessels (i.e., vessel UFP-VSL-T02A in the PEP; and vessels UFP-VSL-00002A and B in the WTP PTF). The second scenario has caustic leaching conducted in the UFP-1 ultrafiltration feed preparation vessels (i.e., vessels UFP-VSL-T01A and B in the PEP; vessels UFP-VSL-00001A and B in the WTP PTF). In both scenarios, 19-M sodium hydroxide solution (NaOH, caustic) …

We present experimental studies of the gain length and saturation power level from 1.5 nm to 1.5 Angstroms at the Linac Coherent Light Source (LCLS). By disrupting theFEL process with an orbit kick, we are able to measure the X-ray intensity as a function of undulator length. This kick method is cross-checked with the method of removing undulator sections. We also study the FEL-induced electron energy loss after saturation to determine the optimal taper of the undulator K values. The experimental results are compared to theory and simulations.

The second scenario has caustic leaching conducted in the UFP-VSL-T02A ultrafiltration feed preparation vessel, identified as Integrated Test B. Washing operations in PEP Integrated Tests A and B were conducted successfully as per the approved run sheets. However, various minor instrumental problems occurred, and some of the process conditions specified in the run sheet were not met during the wash operations, such as filter-loop flow-rate targets not …

The second stage of the FERMI FEL, named FEL-2, is based on the principle of high-gain harmonic generation and relies on a double-seeded cascade. Recent developments stimulated a revision of the original setup, which was designed to cover the spectral range between 40 and 10 nm. The numerical simulations we present here show that the nominal (expected) electron-beam performance allows extension of the FEL spectral range down to 4 nm. A significant amount of third harmonic power can be also expected. We also show that the proposed setup is flexible enough for exploiting future developments of new seed sources, e.g., high harmonic generation in gases.

The Department of Energy Livermore Site Office requested a technical review of remedial alternatives proposed for the Building 812 Operable Unit, Site 300 at the Lawrence Livermore National Laboratory. The team visited the site and reviewed the alternatives proposed for soil remediation in the draft RI/FS and made the following observations and recommendations. Based on the current information available for the site, the team did not identify a single technology that would be cost effective and/or ecologically sound to remediate DU contamination at Building 812 to current remedial goals. Soil washing is not a viable alternative and should not be considered at the site unless final remediation levels can be negotiated to significantly higher levels. This recommendation is based on the results of soil washing treatability studies at Fernald and Ashtabula that suggest that the technology would only be effective to address final remediation levels higher than 50 pCi/g. The technical review team identified four areas of technical uncertainty that should be resolved before the final selection of a preferred remedial strategy is made. Areas of significant technical uncertainty that should be addressed include: (1) Better delineation of the spatial distribution of surface contamination and the vertical distribution of subsurface …

Epigenetics refers to the study of heritable changes in genome function that occur without a change in primary DNA sequence. The 2009 Gordon Conference in Epigenetics will feature discussion of various epigenetic phenomena, emerging understanding of their underlying mechanisms, and the growing appreciation that human, animal, and plant health all depend on proper epigenetic control. Special emphasis will be placed on genome-environment interactions particularly as they relate to human disease. Towards improving knowledge of molecular mechanisms, the conference will feature international leaders studying the roles of higher order chromatin structure, noncoding RNA, repeat elements, nuclear organization, and morphogenic evolution. Traditional and new model organisms are selected from plants, fungi, and metazoans.

Natural gamma-ray background is composed of four components; which include cosmic rays, cosmic ray produced atmospheric activity, terrestrial sources, and skyshine from terrestrial sources. Skyshine is radiation scattered from the air above a source that can produce a signal in radiation detection instrumentation. Skyshine has been studied for many years but its contribution to the natural background observed in a detector has not been studied. A large NaI(Tl) detector was used to investigate each of the four components of the natural background using a series of 48-hour measurements and appropriate lead shielding configured to discriminate contributions from each component. It was found that while the contribution from skyshine decreases rapidly with energy, it represents a significant portion of the background spectrum below ~500keV. A similar campaign of measurements using a HPGe detector is underway.
