Military Disability Retirement: Closer Monitoring Would Improve the Temporary Retirement Process
A letter report issued by the Government Accountability Office with an abstract that begins "Service members found unfit for duty due to a service-related illness or injury may be eligible for military disability retirement. When their disability is not stable, however, they may be placed on the military's Temporary Disability Retired List (TDRL) and granted temporary benefits for as long as 5 years. GAO was asked to respond to concerns about TDRL caseloads, management, and impact on servicemembers. To address these concerns, we analyzed TDRL data; interviewed military officials; reviewed laws, regulations, and other relevant documents; and conducted 12 focus groups with temporary retirees. This report examines (1) recent trends in the TDRL caseload size, (2) recent trends in the characteristics of those placed on the TDRL, (3) disability retirement outcomes for TDRL placements, (4) the adequacy of TDRL management, and (5) the adequacy of information provided to TDRL retirees."

Mortgage Financing: HUD Could Realize Additional Benefits from Its Mortgage Scorecard
A letter report issued by the Government Accountability Office with an abstract that begins "Along with private mortgage providers, the Department of Housing and Urban Development's (HUD) Federal Housing Administration (FHA) has been impacted by technological advances that began in the mid-1990s and that have significantly affected the way the mortgage industry works. As a result, in 2004, FHA implemented Technology Open to Approved Lenders (TOTAL) Scorecard--an automated tool that evaluates the majority of new loans insured by FHA. However, questions have emerged about the effectiveness of TOTAL. Given these concerns, you asked GAO to evaluate the way the agency developed and uses this new tool. This report looks at (1) the reasonableness of FHA's approach to developing TOTAL and (2) the potential benefits to HUD of expanding its use of TOTAL."

Foreign Assistance: Various Challenges Impede the Efficiency and Effectiveness of U.S. Food Aid
A letter report issued by the Government Accountability Office with an abstract that begins "The United States is the largest global food aid donor, accounting for over half of all food aid supplies to alleviate hunger and support development. Since 2002, Congress has appropriated an average of $2 billion per year for U.S. food aid programs, which delivered an average of 4 million metric tons of food commodities per year. Despite growing demand for food aid, rising business and transportation costs have contributed to a 52 percent decline in average tonnage delivered over the last 5 years. These costs represent 65 percent of total emergency food aid, highlighting the need to maximize its efficiency and effectiveness. Based on analysis of agency documents, interviews with experts and practitioners, and fieldwork, this report examines some key challenges to the (1) efficiency of U.S. food aid programs and (2) effective use of U.S. food aid."

Federal Real Property: Progress Made Toward Addressing Problems, but Underlying Obstacles Continue to Hamper Reform
A letter report issued by the Government Accountability Office with an abstract that begins "GAO prepared this report under the Comptroller General's authority to conduct evaluations on his own initiative to assist Congress. Federal real property is a high-risk area due to excess and deteriorating property, reliance on costly leasing, unreliable data, and security challenges. GAO's objectives were to determine (1) what progress the administration and major real property-holding agencies have made in strategically managing real property and addressing long-standing problems and (2) what problems and obstacles, if any, remain to be addressed. GAO reviewed documents and interviewed officials from the Office of Management and Budget (OMB) and nine agencies that hold 93 percent of federal property."

Sarbanes-Oxley Act: Consideration of Key Principles Needed in Addressing Implementation for Smaller Public Companies
A letter report issued by the Government Accountability Office with an abstract that begins "Congress passed the Sarbanes-Oxley Act to help protect investors and restore investor confidence. While the act has generally been recognized as important and necessary, some concerns have been expressed about the cost for small businesses. In this report, GAO (1) analyzes the impact of the Sarbanes-Oxley Act on smaller public companies, particularly in terms of compliance costs; (2) describes responses of the Securities and Exchange Commission (SEC) and Public Company Accounting Oversight Board (PCAOB) to concerns raised by smaller public companies; and (3) analyzes smaller public companies' access to auditing services and the extent to which the share of public companies audited by mid-sized and small accounting firms has changed since the act was passed."

DOD's High-Risk Areas: Successful Business Transformation Requires Sound Strategic Planning and Sustained Leadership
Testimony issued by the Government Accountability Office with an abstract that begins "In January 2005, GAO released its 2005 high-risk series update report for the 109th Congress. GAO's high-risk series has increasingly focused on major government programs and operations that need urgent attention and transformation to ensure that the U.S. government functions in the most economical, efficient, and effective manner possible. GAO also emphasizes those federal programs and operations that are at high risk because of their greater vulnerabilities to fraud, waste, abuse, and mismanagement. Of the 25 areas on GAO's 2005 high-risk list, 8 are Department of Defense (DOD) programs or operations and 6 are governmentwide high-risk areas for which DOD shares some responsibility. These high-risk areas touch on all of DOD's major business operations. DOD's failure to effectively address these many high-risk areas results in billions of dollars of waste each year and inadequate accountability to Congress and the American people. Congress asked GAO to provide its views on (1) DOD's high-risk areas, including those it shares responsibility for with other federal agencies; (2) an emerging challenge for DOD that merits close attention, involving DOD's approach to risk management; and (3) key elements, such as a chief management …

Human Capital: The Role of the Ombudsmen in Dispute Resolution
A letter report issued by the General Accounting Office with an abstract that begins "Federal agencies have created ombudsmen offices to expedite the resolution of employees' complaints about workplace issues. An ombudsman provides an informal alternative to more formal administrative processes in the workplace, using various techniques and often working "outside the box" to deal with conflicts and other organizational disputes. GAO found that the number of ombudsman offices handling workplace issues in federal agencies is small but is expected to grow. These offices deal with a wide range of workplace issues, from helping employees get answers to questions about agency policies and cutting through "red tape" to more serious situations, such as allegations about employment discrimination. In studying the ombudsmen offices at the National Institutes of Health (NIH), the International Broadcasting Bureau (IBB), and the U.S. Secret Service, GAO found some common approaches as well as some differences in their operations. Common to all three offices was their broad responsibility and authority to deal with almost any workplace issue, their ability to bring systemic issues to management's attention, and the way in which they worked with other agency offices in providing assistance to employees. But how they were structured …

National Airspace System: Experts' Views on Improving the U.S. Air Traffic Control Modernization Program
Other written product issued by the Government Accountability Office with an abstract that begins "In 1981, the Federal Aviation Administration (FAA) began a program to modernize the national airspace system and a primary component, the air traffic control (ATC) system. The ATC component of this program, which is designed to replace aging equipment and accommodate predicted growth in air traffic, has had difficulty for more than two decades in meeting cost, schedule, and performance targets. The performance-based Air Traffic Organization (ATO) was created in February 2004 to improve the management of the modernization effort. On October 7, 2004, GAO hosted a panel to discuss attempts to address the ATC modernization program's persistent problems. Participants discussed the factors that they believed have affected FAA's ability to acquire new ATC systems. Participants also identified steps that FAA's ATO could take in the short term to address these factors, as well as longer term steps that could be taken to improve the modernization program's chances of success and help the ATO achieve its mission. The participants included domestic and foreign aviation experts from industry, government, private think tanks, and academia. They are recognized for their expertise in aviation safety, economics, and engineering; transportation …

Title Insurance: Actions Needed to Improve Oversight of the Title Industry and Better Protect Consumers
A letter report issued by the Government Accountability Office with an abstract that begins "In a previous report and testimony, GAO identified issues related to title insurance markets, including questions about the extent to which premium rates reflect underlying costs, oversight of title agent practices, and the implications of recent state and federal investigations. This report addresses those issues by examining (1) the characteristics of title insurance markets across states, (2) factors influencing competition and prices within those markets, and (3) the current regulatory environment and planned regulatory changes. To conduct this review, GAO analyzed available industry data and studies, and interviewed industry and regulatory officials in a sample of six states selected on the basis of differences in size, industry practices, regulatory environments, and number of investigations."

Multi-year search for a diffuse flxu of muon neutrinos with AMANDA-II
A search for TeV-PeV muon neutrinos from unresolved sources was performed on AMANDA-II data collected between 2000 and 2003 with an equivalent livetime of 807 days. This diffuse analysis sought to find an extraterrestrial neutrino flux from sources with non-thermal components. The signal is expected to have a harder spectrum than the atmospheric muon and neutrino backgrounds. Since no excess of events was seen in the data over the expected background, an upper limit of E{sup 2}{Phi}{sub 90%C.L.} < 7.4 x 10{sup -8} GeV cm{sup -2} s{sup -1} sr{sup -1} is placed on the diffuse flux of muon neutrinos with a {Phi} {proportional_to} E{sup -2} spectrum in the energy range 16 TeV to 2.5 PeV. This is currently the most sensitive {Phi} {proportional_to} E{sup -2} diffuse astrophysical neutrino limit. We also set upper limits for astrophysical and prompt neutrino models, all of which have spectra different than {Phi} {proportional_to} E{sup -2}.

Shielding Calculations for NSLS-II Beamlines.
Brookhaven National Laboratory is in the process of designing a new Electron Synchrotron for scientific research using synchrotron radiation. This facility, called the 'National Synchrotron Light Source II' (NSLS-II), will provide x-ray radiation of ultra-high brightness and exceptional spatial and energy resolution. It will also provide advanced insertion devices, optics, detectors, and robotics, and a suite of scientific instruments designed to maximize the scientific output of the facility. The project scope includes the design, construction, installation, and commissioning of the following accelerators: a 200 MeV linac, a booster accelerator operating from 200 MeV to 3.0 GeV, the storage ring which stores 500 mA current of electrons at an energy of 3.0 GeV and 56 beamlines for experiments. It is planned to operate the facility primarily in a top-off mode, thereby maintaining the maximum variation in stored beam current to < 1%. Because of the very demanding requirements for beam emittance and synchrotron radiation brilliance, the beam life-time is expected to be quite low, on the order of 2 hours. Each of the 56 beamlines will be unique in terms of the source properties and configuration. The shielding designs for five representative beamlines are discussed in this paper.

Role of Fluid Pressure in the Production Behavior of EnhancedGeothermal Systems with CO2 as Working Fluid
Numerical simulation is used to evaluate mass flow and heatextraction rates from enhanced geothermal injection-production systemsthat are operated using either CO2 or water as heat transmission fluid.For a model system patterned after the European hot dry rock experimentat Soultz, we find significantly greater heat extraction rates for CO2 ascompared to water. The strong dependence of CO2 mobility (=density/viscosity) upon temperature and pressure may lead to unusualproduction behavior, where heat extraction rates can actually increasefor a time, even as the reservoir is subject to thermaldepletion.

Achievable magnetic fields of super-ferric helical undulators for the ILC.
The magnetic fields on the beam axis of helical undulators for the proposed International Linear Collider (ILC) gamma-ray production were calculated for undulator periods of 10 mm and 12 mm. The calculation assumed the use of low-carbon steel for the magnetic poles and a beam chamber outer diameter of 6.3 mm. Using NbTi superconducting coils at 4.2 K, the on-axis field for a 10-mm-period undulator was 0.62 T at the critical current density. The field for a 12-mm undulator period was 0.95 T, which gives a K value of 1.06. The K value for an 11-mm undulator with Nb{sub 3}Sn superconducting coils was estimated to about 1.1.

Predicted Effects of Prescribed Burning and Timber Management on Forest Recovery and Sustainability at Fort Benning, Georgia
The objective of this work was to use a simple compartment model of soil carbon (C) and nitrogen (N) dynamics to predict forest recovery on degraded soils and forest sustainability, following recovery, under different regimes of prescribed fire and timber management. This report describes the model and a model-based analysis of the effect of prescribed burning and forest thinning or clearcutting on stand recovery and sustainability at Fort Benning, GA. I developed the model using Stella{reg_sign} Research Software (High Performance Systems, Inc., Hanover, NH) and parameterized the model using data from field studies at Fort Benning, literature sources, and parameter fitting. The model included (1) a tree biomass submodel that predicted aboveground and belowground tree biomass, (2) a litter production submodel that predicted the dynamics of herbaceous aboveground and belowground biomass, (3) a soil C and N submodel that predicted soil C and N stocks (to a 30 cm soil depth) and net soil N mineralization, and (4) an excess N submodel that calculated the difference between predicted plant N demands and soil N supplies. There was a modeled feedback from potential excess N (PEN) to tree growth such that forest growth was limited under conditions of N deficiency. Two …

Soil Carbon Dynamics Along an Elevation Gradient in the Southern Appalachian Mountains
The role of soil C dynamics in the exchange of CO{sub 2} between the terrestrial biosphere and the atmosphere is at the center of many science questions related to global climate change. The purpose of this report is to summarize measured trends in environmental factors and ecosystem processes that affect soil C balance along elevation gradients in the southern Appalachian Mountains of eastern Tennessee and western North Carolina, USA. Three environmental factors that have potentially significant effects on soil C dynamics (temperature, precipitation, and soil N availability) vary in a predictable manner with altitude. Forest soil C stocks and calculated turnover times of labile soil C increase with elevation, and there is an apparent inverse relationship between soil C storage and mean annual temperature. Relationships between climate variables and soil C dynamics along elevation gradients must be interpreted with caution because litter chemistry, soil moisture, N availability, and temperature are confounded; all potentially interact in complex ways to regulate soil C storage through effects on decomposition. Some recommendations are presented for untangling these complexities. It is concluded that past studies along elevation gradients have contributed to a better but not complete understanding of environmental factors and processes that potentially affect …

Mass- and temperature-dependent diffusion coefficients for lightnoble gases for the TOUGH2-EOSN Model
This report describes modifications made to the EOSN module(Shan and Pruess, 2003) of the nonisothermal multiphase flow simulatorTOUGH2 (Pruess, et al., 1999). The EOSN fluid property module simulatestransport of water, brine, air, and noble gases or CO2 in the subsurface.In the standard version of the EOSN module, diffusion coefficients can bespecified by the user, but there is no allowance for liquid-phasediffusion coefficients to change with temperature. Furthermore, usersmust specify radiogenic sources of heat and helium for each element indata block GENER, which can be a time-consuming task for models withlarge numbers of elements. Our modifications seek to increase thefunctionality and efficiency of using TOUGH2-EOSN by allowing for mass-and temperature-dependent liquid-phase diffusion coefficients for heliumand neon and specification of radiogenic heat and helium production as aproperty of a material. The modified version is based on TOUGH2-EOSN andthus requires familiarity with the capabilities and input formats of theTOUGH2 code (Pruess, et al., 1999) and the EOSN module (Shan and Pruess,2003). This report only details our modifications and how to properlyutilize them.
