Water fluxes in unsaturated, fractured rock involve the physical processes occurring at fracture-matrix interfaces within fracture networks. Modeling these water fluxes using a discrete fracture network model is a complicated effort. Existing preprocessors for TOUGH2 are not suitable to generate grids for fracture networks with various orientations and inclinations. There are several 3-D discrete-fracture-network simulators for flow and transport, but most of them do not capture fracture-matrix interaction. We have developed a new 3-D discrete-fracture-network mesh generator, FRACMESH, to provide TOUGH2 with information about the fracture network configuration and fracture-matrix interactions. FRACMESH transforms a discrete fracture network into a 3 dimensional uniform mesh, in which fractures are considered as elements with unique rock material properties and connected to surrounding matrix elements. Using FRACMESH, individual fractures may have uniform or random aperture distributions to consider heterogeneity. Fracture element volumes and interfacial areas are calculated from fracture geometry within individual elements. By using FRACMESH and TOUGH2, fractures with various inclinations and orientations, and fracture-matrix interaction, can be incorporated. In this paper, results of flow and transport simulations in a fractured rock block utilizing FRACMESH are presented.

Appropriations are one part of a complex federal budget process that includes budget resolutions, appropriations (regular, supplemental, and continuing) bills, rescissions, and budget reconciliation bills. This Report is a guide to one of the 13 regular appropriations bills that Congress passes each year. It is designed to supplement the information provided by the House and Senate Appropriations Subcommittee on VA, HUD, and Independent Agencies.

The nation’s health, wealth, and security rely on the production and distribution of certain goods and services. The array of physical assets, processes and organizations across which these goods and services move are called critical infrastructures (e.g. electricity, the power plants that generate it, and the electric grid upon which it is distributed). Computers and communications, themselves critical infrastructures, are increasingly tying these infrastructures together. This report aims to address the concern that this reliance on computers and computer networks raises the vulnerability of the nation’s critical infrastructures to “cyber” attacks.

This report provides information on the Office of Management and Budget’s (OMB) Circular A-76, “Performance of Commercial Activities,” and the impact of a related reform initiative, the Federal Activities Inventory Reform Act (FAIR) of 1998, within the Department of Defense. The Circular defines federal policy for determining whether recurring commercial activities should be outsourced to commercial sources, Governmental facilities, or through inter-service support agreements. The FAIR Act creates statutory reporting requirements for federal executive agencies, by requiring Federal executive agencies to identify activities “not inherently governmental” and consider outsourcing through managed competitions. However, FAIR does not require that agencies contract out these activities.

Correspondence issued by the General Accounting Office with an abstract that begins "Weaknesses in the Department of Housing and Urban Development's (HUD) financial management systems have been a long-standing challenge for the department and have contributed to our designating two of its major programs areas as high-risk and the financial management information systems in particular as a major management challenge. While some progress has been made, both GAO and the HUD Office of the Inspector General (IG) have reported extensively on weaknesses related to HUD's financial management systems. In audits of HUD's consolidated financial statements, the IG has consistently identified several material internal control weaknesses resulting from inadequate financial management systems. In recent audit reports, the HUD OIG also noted that the completion of the development of adequate financial management systems is the most critical need faced by HUD in improving its financial management control environment. Responsive financial management systems are particularly critical to HUD's ability to meet its mission, deliver key services, and establish sufficient management control over its operations. In light of these issues, Congress asked that we (1) summarize HUD's past efforts to implement an integrated financial management system, (2) identify the challenges HUD faces with its …

Ap/Bp stars are magnetic chemically peculiar early A and late B type stars of the main sequence. They exhibit peculiar surface abundance anomalies that are thought to be the result of gravitational settling and radiative levitation. The physics of diffusion in these stars are reviewed briefly and some model predictions are discussed. While models reproduce some observations reasonably well, more work is needed before the behavior of diffusing elements in a complex magnetic field is fully understood.

This report provides an overview of Federal Research and Development funding for FY2004.

Testimony issued by the General Accounting Office with an abstract that begins "GAO is a key source of objective information and analyses and, as such, plays a crucial role in supporting congressional decision-making and helping improve government for the benefit of the American people. This testimony focuses on GAO's (1) fiscal year 2002 performance and results, (2) efforts to maximize our effectiveness, responsiveness and value, and (3) our budget request for fiscal year 2004 to support the Congress and serve the American public."

A letter report issued by the General Accounting Office with an abstract that begins "Constructing, improving, and repairing roads is fundamental to meeting the nation's mobility needs. The Federal Highway Administration (FHWA) supplies most of the money (about $20 billion in fiscal year 2003), and state departments of transportation are primarily responsible for completing projects. Many federal and state agencies (called resource agencies) help ensure that environmental and other concerns are considered. These and other organizations have recognized that the time it takes to complete complex federally funded highway projects is too long--in some cases nearly 20 years. GAO was asked to report the views of knowledgeable officials on the most promising approaches for reducing completion time for federally funded highway projects. GAO obtained the views of 33 officials from federal, state, and private organizations with interests in federally funded roads."

This report details the history of the three federal transfer taxes, tracing their development from their eighteenth century roots to the present.

In this report, the history of the federal transfer taxes, has been divided into four parts: (1) the federal death and gift taxes utilized in the period 1789 to 1915; (2) the development of the modern estate and gift taxes from 1916 through 1975; (3) the creation and refinement of a unified estate and gift tax system, supplemented by a generation-skipping transfer tax; and (4) the phase out and repeal of the estate and generation-skipping taxes, with the gift tax being retained as a device to protect the integrity of the income tax.

Testimony issued by the General Accounting Office with an abstract that begins "Following the bioterrorist events of the fall of 2001, there has been concern that the nation may not be prepared to respond to a major public health threat, such as the current outbreak of Severe Acute Respiratory Syndrome (SARS). Whether a disease outbreak occurs naturally or is due to the intentional release of a harmful biological agent by a terrorist, much of the initial response would occur at the local level, particularly hospitals and their emergency departments. Efforts to plan for worldwide influenza pandemics are useful for understanding public health preparedness for other large-scale outbreaks. GAO was asked to examine (1) the preparedness of state and local public health agencies and organizations for responding to a large-scale infectious disease outbreak, (2) the preparedness of hospitals for responding to a large-scale infectious disease outbreak, and (3) federal and state efforts to prepare for an influenza pandemic. This testimony is based on GAO's report, Bioterrorism: Preparedness Varied across State and Local Jurisdictions, GAO-03-373 (Apr. 7, 2003), a survey of hospitals GAO conducted to assess their level of emergency preparedness, and information updating GAO's prior report on federal and state planning …
