Recycling: Additional Efforts Could Increase Municipal Recycling

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Although recycling can generate environmental and economic benefits, the national recycling rate has increased only slightly since 2000, according to the Environmental Protection Agency (EPA). While local governments have the primary role in operating recycling programs, EPA and the Department of Commerce (Commerce) have some legal responsibilities for encouraging recycling. GAO was asked to (1) identif… more

Long-Term Care Insurance: Federal Program Has a Unique Profit Structure and Faced a Significant Marketing Challenge

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Spending on long-term care services--about $193 billion in 2004--is expected to rise. In 2000, Congress passed the Long-Term Care Security Act, requiring the federal government to offer long-term care insurance. To do so, the Office of Personnel Management (OPM) contracted with Long Term Care Partners LLC (Partners) to create the Federal Long Term Care Insurance Program. This is the second of two report… more

Recovery of Fresh Water Resources from Desalination of Brine Produced During Oil and Gas Production Operations

Description: Management and disposal of produced water is one of the most important problems associated with oil and gas (O&G) production. O&G production operations generate large volumes of brine water along with the petroleum resource. Currently, produced water is treated as a waste and is not available for any beneficial purposes for the communities where oil and gas is produced. Produced water contains different contaminants that must be removed before it can be used for any beneficial surface a… more

Using DUSTRAN to Simulate Fog-Oil Dispersion and Its Impacts on Local Insect Populations at Ft. Hood: Final Report

Description: Smokes and obscurants (S&O) are important screening agents used during military training exercises on many military installations. Although the use of S&O is subject to environmental laws, the fate and effects of S&O on natural habitats are not well documented. One particular concern is the impact S&O may have on local insect populations, which can be important components of terrestrial food chains of endangered species. Fog-oil (FO) is an S&O that is of particular concern. An important part of… more

Calculated concrete target damage by multiple rod impact and penetration

Description: The effect of enhanced crater formation has been demonstrated experimentally when multiple and delayed shaped charge jets impact and penetrate concrete. The concept for enhancement utilizes a single follow-on jet at the centerline of holes produced by multiple precursor jets penetrating the surrounding the region. Calculations of the 3D crater enhancement phenomena have been conducted with multiple rods to simulate the steady state portion of the multiple jet penetration process. It is expected… more

Design and Evaluation of a Virtual Quadrant Receiver for 4-ary Pulse Position Modulation/Optical Code Division Multiple Access (4-ary PPM/O-CDMA)

Description: M-ary pulse position modulation (M-ary PPM) is an alternative to on-off-keying (OOK) that transmits multiple bits as a single symbol occupying a frame of M slots. PPM does not require thresholding as in OOK signaling, instead performing a comparison test among all slots in a frame to make the slot decision. Combining PPM with optical code division multiple access (PPM/O-CDMA) adds the benefit of supporting multiple concurrent, asynchronous bursty PPM users. While the advantages of PPM/O-CDMA ar… more

Aluminum Bronze Alloys to Improve the System Life of Basic Oxygen and Electric Arc Furnace Hoods, Roofs and Side Vents.

Description: Energy Industries of Ohio was the lead organization for a consortium that examined the current situation involving the service life of electric arc and basic oxygen furnace hoods, roofs and side vents. Republic Engineered Products (REP), one of the project partners, installed a full-scale Al-Bronze “skirt” in their BOF at their Lorain OH facility, believed to be the first such installation of this alloy in this service. In 24 months of operation, the Al-Bronze skirt has processed a total of 4,5… more

Code Verification Results of an LLNL ASC Code on Some Tri-Lab Verification Test Suite Problems

Description: As scientific codes become more complex and involve larger numbers of developers and algorithms, chances for algorithmic implementation mistakes increase. In this environment, code verification becomes essential to building confidence in the code implementation. This paper will present first results of a new code verification effort within LLNL's B Division. In particular, we will show results of code verification of the LLNL ASC ARES code on the test problems: Su Olson non-equilibrium radiatio… more

A Bloch-Torrey Equation for Diffusion in a Deforming Media

Description: Diffusion Tensor Magnetic Resonance Imaging (DTMRI)technique enables the measurement of diffusion parameters and therefore,informs on the structure of the biological tissue. This technique isapplied with success to the static organs such as brain. However, thediffusion measurement on the dynamically deformable organs such as thein-vivo heart is a complex problem that has however a great potential inthe measurement of cardiac health. In order to understand the behavior ofthe Magnetic Resonance (… more
