Self-Organized Megastructures in Sedimentary Basins
The overall theme of the project is to develop a quantitative understanding of basin reaction/transport/mechanical (RTM) processes on a broad range of scales. Our approach starts with the development of novel formulations of the basic RTM process rate laws (e.g. rock deformation, texture dynamics, and fracturing). We then set forth algorithms for solving the resulting partial differential equations numerically. As many of the parameters in the subsurface are not well known, we embed the entire approach in a probabilistic framework through information theory. The result is a set of novel software and conceptual papers that have been the first quantitative theory of a number of fundamental phenomena that take into account the full RTM dynamics of these systems.

Slurry Molding Technologies for Novel Carbon and Graphite Materials
The Oak Ridge National Laboratory (ORNL) has developed a slurry molding technology for the manufacture of porous, high surface area, carbon fiber composites molecular sieves, and carbon-carbon composite preforms. Potentially, this technology could be applied to the manufacture of a host of novel carbon materials including porous adsorbent carbons, low-pressure drop adsorbent carbon composites, ultra-fine-grained graphite, and carbon fiber reinforced graphite. New opportunities for high surface carbon fiber composite molecular sieve (CFCMS) materials are now emerging. Many of these opportunities are driven by increasingly harsh environmental pressures. Traditional granular activated carbon (GAC) is not suitable for many of these applications because of the difficulties encountered with attrition and in forming ''structures'' which have the necessary mechanical and physical properties. In addition, the electrical desorption of adsorbed species is not possible with GAC due to its low bulk electrical conductivity. Activated carbon fibers have been found to be useful in some applications. Work by ORNL has shown, for example, that CFCMS materials are capable of adsorbing various gases and desorbing them under electrical stimulation. For some applications these fibers have to be formed into a structure that can offer the desired mechanical integrity and pressure drop characteristics. To date, the work …

Surface Transportation: Many Factors Affect Investment Decisions
A letter report issued by the General Accounting Office with an abstract that begins "Passenger and freight traffic are expected to grow substantially in the future, generating additional congestion and requiring continued investment in the nation's surface transportation system. Over the past 12 years, the federal government has provided hundreds of billions of dollars for investment in surface transportation projects through the Intermodal Surface Transportation Efficiency Act of 1991 and its successor legislation, the Transportation Equity Act for the 21st Century. Reauthorization of this legislation is expected to provide hundreds of billions of dollars more in federal funding for surface transportation projects. For this investment to have the greatest positive effect, agencies at all levels of government need to select investments that yield the greatest benefits for a given level of cost. This report provides information about the processes that state and regional transportation decisionmakers use to analyze and select transportation infrastructure investments. GAO identified (1) key federal requirements for planning and deciding on such investments, (2) how benefit-cost analysis facilitates sound decisionmaking, and (3) other factors that decision-makers consider in evaluating and deciding on investments."

Testing efficiency of storage in the subsurface: frio brine pilot experiment
Can we demonstrate that subsurface storage is an effective method of reducing emissions of CO2 to the atmosphere? The Frio Brine Pilot Experiment is designed to test storage performance of a typical subsurface environment in an area where large-volume sources and sinks are abundant, near Houston, Texas, USA. We employed extensive pre-experiment characterization and modeling to identify significant factors that increase or decrease risk of leakage from the injection zone. We then designed the experiment to focus on those factors, as well as to test for presence or absence of events that are not expected. A fully developed reservoir model of heterogeneous reworked fluvial sandstones of the Frio Formation documents three-dimensional compartmentalization of the injection horizon by faulting associated with salt-dome intrusion and growth. Modeling using the TOUGH2 simulator showed that a significant source of uncertainty for subsurface performance of injected CO2 is residual CO2 saturation during storage. If initial displacement of water during injection is efficient and capillary effects create the expected residual saturation of 30 percent CO2, the volume occupied by the plume will be limited, and long-term storage can be expected even in an open system. If, however, during injection, CO2 moves out from the injection well …

Thermal Effects During CO2 Leakage from a Geologic Storage Reservoir
Leakage of CO2 from a geologic storage reservoir along an idealized fault zone has been simulated, including transitions between supercritical, liquid, and gaseous CO2. We find strong non-isothermal effects and nonmonotonic leakage behavior, due to an interplay between multiphase flow and heat transfer effects.

Transcription-Driven Twin Supercoiling of a DNA Loop: A Brownian Dynamics Study
The torque generated by RNA polymerase as it tracks along double-stranded DNA can potentially induce long-range structural deformations integral to mechanisms of biological significance in both prokaryotes and eukaryotes. In this report, we introduce a dynamic computer model for investigating this phenomenon. Duplex DNA is represented as a chain of hydrodynamic bends interacting through elastic potentials. The chain, linear when relaxed, is looped to form two open but topologically constrained subdomains. This permits the dynamic introduction of torsional stress via a centrally applied torque. We simulate by Brownian dynamics the 100 {micro}s response of a 477-basepair B-DNA template to the localized torque generated by the prokaryotic transcription ensemble. Following a sharp rise at early times, the distributed twist assumes a nearly constant value in both subdomains, and a succession of supercoiling deformations occurs as superhelical stress is increasingly partitioned to writhe. The magnitude of writhe surpasses that of twist before also leveling off when the structure reaches mechanical equilibrium with the torsional load. Superhelicity is simultaneously right-handed in one subdomain and left-handed in the other. The properties of the chain at the onset of writhing agree well with predictions from theory, and the generated stress is ample for driving secondary …

Transitional Medical Assistance (TMA) Under Medicaid
Medicaid, a means-tested federal/state program that provides health care coverage to certain groups of individuals, requires that states continue Medicaid benefits for certain low-income families who would otherwise lose coverage because of changes in their income. This continuation of benefits is known as transitional medical assistance (TMA). The law permanently requires four months of TMA for families who lose Medicaid eligibility due to increased child or spousal support collections, as well as those who lose eligibility due to an increase in earned income or hours of employment. Congress expanded work-related TMA under Section 1925 of the Social Security Act as part of the Family Support Act of 1988, and states currently must provide TMA to families who lose Medicaid eligibility for work-related reasons for at least six, and up to 12, months.

Transport, Targeting, and Applications of Metallic Functional Nanoparticles for Degradation of DNAPL Chlorinated Organic solvents
The goals of this project have been to synthesize reactive metal colloids capable of: (1) reductively degrading chlorinated solvents, (2) being transported in porous media, and (3) partitioning from aqueous to non-aqueous solvents or accumulating at water/organic solvent interfaces. This project addresses the need for methods to efficiently remove or degrade dense non-aqueous phase liquid (DNAPL) contaminants, and that act as long-term sources of groundwater contamination through slow solubilization. This project builds on a general particle-based approach to subsurface contaminant remediation that has been demonstrated by others in the successful degradation of chlorinated compounds dissolved in groundwater using Fe(0) colloids. Delivering reactive particles directly to the surface of the DNAPL will decompose the pollutant into benign materials, reduce the migration of pollutant during treatment, possibly lead to encapsulation of the DNAPL, and reduce the time needed to remove residual pollution by other means, such as natural attenuation. Specific research challenges include: Synthesis of reactive particles that can be deployed in aqueous environments, modification of the particle surfaces, and modeling the transport behavior in porous media containing pendant chlorinated solvent.

TREATMENT OF HYDROCARBON, ORGANIC RESIDUE AND PRODUCTION CHEMICAL DAMAGE MECHANISMS THROUGH THE APPLICATION OF CARBON DIOXIDE IN NATURAL GAS STORAGE WELLS
Two gas storage fields were studied for this project. Overisel field, operated by Consumer's Energy, is located near the town of Holland, Michigan. Huntsman Storage Unit, operated by Kinder Morgan, is located in Cheyenne County, Nebraska near the town of Sidney. Wells in both fields experienced declining performance over several years of their annual injection/production cycle. In both fields, the presence of hydrocarbons, organic materials or production chemicals was suspected as the cause of progressive formation damage leading to the performance decline. Core specimens and several material samples were collected from these two natural gas storage reservoirs. Laboratory studies were performed to characterize the samples that were believed to be representative of a reservoir damage mechanism previously identified as arising from the presence of hydrocarbons, organic residues or production chemicals. A series of laboratory experiments were performed to identify the sample materials, use these materials to damage the flow capacity of the core specimens and then attempt to remove or reduce the induced damage using either carbon dioxide or a mixture of carbon dioxide and other chemicals. Results of the experiments showed that pure carbon dioxide was effective in restoring flow capacity to the core specimens in several different settings. …

Unemployment Compensation: Benefits While on Leave for the Birth or Adoption of a Child
The Temporary Extended Unemployment Compensation Act of 2002 (TEUC), was signed into law March 9, 2002, as a part of P.L. 107-147. TEUC provides up to 13 weeks of additional federally funded unemployment compensation (UC) to individuals in all states who exhaust their regular UC benefits. TEUC also provides a second 13 weeks of benefits to individuals who exhaust their benefits in a high-unemployment state. On January 8, 2003, Congress passed S. 23 (P.L. 108-1) extending the TEUC program through May 31, 2003, and phasing-out benefits through August 30,2003. This report will be updated as events warrant.

Unlocking the potential for efficiency and demand response throughadvanced metering
Reliance on the standard cumulative kilowatt-hour meter substantially compromises energy efficiency and demand response programs. Without advanced metering, utilities cannot support time-differentiated rates or collect the detailed customer usage information necessary to (1)educate the customer to the economic value of efficiency and demand response options, or (2) distribute load management incentives proportional to customer contribution. These deficiencies prevent the customer feedback mechanisms that would otherwise encourage economically sound demand-side investments and behaviors. Thus, the inability to collect or properly price electricity usage handicaps the success of almost all efficiency and demand response options. Historically, implementation of the advanced metering infrastructure (AMI) necessary for the successful efficiency and demand response programs has been prevented by inadequate cost-benefit analyses. A recent California effort has produced an expanded cost-effectiveness methodology for AMI that introduces previously excluded benefits. In addition to utility-centric costs and benefits, the new model includes qualitative and quantitative costs and benefits that accrue to both customers and society.

WASTE CONTAINER AND WASTE PACKAGE PERFORMANCE MODELING TO SUPPORT SAFETY ASSESSMENT OF LOW AND INTERMEDIATE-LEVEL RADIOACTIVE WASTE DISPOSAL.
Prior to subsurface burial of low- and intermediate-level radioactive wastes, a demonstration that disposal of the wastes can be accomplished while protecting the health and safety of the general population is required. The long-time frames over which public safety must be insured necessitates that this demonstration relies, in part, on computer simulations of events and processes that will occur in the future. This demonstration, known as a Safety Assessment, requires understanding the performance of the disposal facility, waste containers, waste forms, and contaminant transport to locations accessible to humans. The objective of the coordinated research program is to examine the state-of-the-art in testing and evaluation short-lived low- and intermediate-level waste packages (container and waste form) in near surface repository conditions. The link between data collection and long-term predictions is modeling. The objective of this study is to review state-of-the-art modeling approaches for waste package performance. This is accomplished by reviewing the fundamental concepts behind safety assessment and demonstrating how waste package models can be used to support safety assessment. Safety assessment for low- and intermediate-level wastes is a complicated process involving assumptions about the appropriate conceptual model to use and the data required to support these models. Typically due to …
