Prediction of Coal ash leaching behavior in acid mine water, comparison of laboratory and field studies

Description: Strongly alkaline fluidized bed combustion ash is commonly used to control acid mine drainage in West Virginia coal mines. Objectives include acid neutralization and immobilization of the primary AMD pollutants: iron, aluminum and manganese. The process has been successful in controlling AMD though doubts remain regarding mobilization of other toxic elements present in the ash. In addition, AMD contains many toxic elements in low concentrations. And, each mine produces AMD of widely varying qua… more

Migration and Entrapment of DNAPLs in Heterogeneous Systems: Impact of Waste and Porous Medium Composition

Description: Dense nonaqueous phase liquids (DNAPLs) pose a significant threat to soil and groundwater at Department of Energy (DOE) sites. Evidence suggests that subsurface wettability variations are present at many of these sites as a result of spatical and temporal variations in aqueous phase chemistry, contaminant aging, mineralogy and organic matter. The presence of such heterogeneity may significantly influence DNAPL migration and entrapment in the saturated zone.

Top physics: search for electroweak single top quark production in p anti-p collisions at s**(1/2) = 1.96 tev

Description: We report on a search for Standard Model t-channel and s-channel single top quark production in p{bar p} collisions at a center of mass energy of 1.96 TeV. We use a data sample corresponding to 162 pb{sup -1} recorded by the upgraded Collider Detector at Fermilab. We find no significant evidence for electroweak top quark production and set upper limits at the 95% confidence level on the production cross section, consistent with the Standard Model: 10.1 pb for the t-channel, 13.6 pb for the s-ch… more

Automated visual direction : LDRD 38623 final report.

Description: Mobile manipulator systems used by emergency response operators consist of an articulated robot arm, a remotely driven base, a collection of cameras, and a remote communications link. Typically the system is completely teleoperated, with the operator using live video feedback to monitor and assess the environment, plan task activities, and to conduct the operations via remote control input devices. The capabilities of these systems are limited, and operators rarely attempt sophisticated operati… more

Individuals with Disabilities Education Act (IDEA): Analysis of Changes Made by P.L. 108-446

Description: This report discusses the Individuals with Disabilities Education Act (IDEA — 20 U.S.C. §1400 et seq.), which is both a grants statute and a civil rights statute. It provides federal funding for the education of children with disabilities and requires, as a condition for the receipt of such funds, the provision of a free appropriate public education (FAPE). The statute also contains detailed due process provisions to ensure the provision of FAPE. Originally enacted in 1975, the act responded t… more

Waste Form Qualification Compliance Strategy for Bulk Vitrification

Description: The Bulk Vitrification System is being pursued to assist in immobilizing the low-activity tank waste from the 53 million gallons of radioactive waste in the 177 underground storage tanks on the Hanford Site. To demonstrate the effectiveness of the bulk vitrification process, a research and development facility known as the Demonstration Bulk Vitrification System (DBVS) is being built to demonstrate the technology. Specific performance requirements for the final packaged bulk vitrification waste… more

Review of The SIAM 100-Digit Challenge: A Study in High-Accuracy Numerical Computing

Description: In the January 2002 edition of SIAM News, Nick Trefethen announced the '$100, 100-Digit Challenge'. In this note he presented ten easy-to-state but hard-to-solve problems of numerical analysis, and challenged readers to find each answer to ten-digit accuracy. Trefethen closed with the enticing comment: 'Hint: They're hard! If anyone gets 50 digits in total, I will be impressed.' This challenge obviously struck a chord in hundreds of numerical mathematicians worldwide, as 94 teams from 25 nation… more

Fiber Optical Micro-Detectors for Oxygen Sensing in Power Plants Progress Report

Description: A reflection mode fiber optic oxygen sensor that can operate at high temperatures for power plant applications is being developed. The sensor is based on the {sup 3}O{sub 2} quenching of the red emission from hexanuclear molybdenum chloride clusters. One of the critical materials issues is to demonstrate that the luminescent cluster immobilized in the sol-gel porous support can withstand high temperature. At the same time the sol-gel matrix must have a high permeability to oxygen. Using a potas… more

Energy Policy: Legislative Proposals in the 109th Congress

Description: While introduction of energy legislation in the 109th Congress is pending, it remains unclear what its course may be. Some believe that the results of the fall 2004 election have heightened prospects for opening up the Arctic National Wildlife Refuge (ANWR) to oil and gas development, and the Republican leadership has indicated that ANWR is to be included in the budget resolution that will come before Congress. Senate Energy and Natural Resources Committee Chairman Pete Domenici has indicated t… more

DEVELOPING STATE POLICIES SUPPORTIVE OF BIOENERGY DEVELOPMENT

Description: Working within the context of the Southern States Biobased Alliance (SSBA) and with officials in each state, the Southern States Energy Board (SSEB) is identifying bioenergy-related policies and programs within each state to determine their impact on the development, deployment or use of bioenergy. In addition, SSEB will determine which policies have impacted industry's efforts to develop, deploy or use biobased technologies or products. As a result, SSEB will work with the Southern States Biob… more

Foreign Intelligence Surveillance Act: Selected Legislation from the 108th Congress

Description: The Foreign Intelligence Surveillance Act, as passed in 1978, provided a statutory framework for the use of electronic surveillance in the context of foreign intelligence gathering. In doing so, Congress sought to strike a balance between national security interests and personal privacy rights. Subsequent legislation expanded federal laws dealing with foreign intelligence gathering to address physical searches, pen registers and trap and trace devices, and access to certain business records.

Agriculture: Prospective Issues for Congress

Description: A number of issues affecting U.S. agriculture could receive attention during the 109th Congress. Some are related to new initiatives or to unfinished legislation from the 108th Congress; others have been the focus of ongoing congressional oversight. Although the current (2002) farm bill (P.L. 107-171) generally does not expire until 2007, the agriculture committees could begin hearings on a new measure as early as 2005. The farm bill spells out the types and levels of benefits provided to produ… more
