Subtask 1.16-Slow-Release Bioremediation Accelerators (open access)

Subtask 1.16-Slow-Release Bioremediation Accelerators

Low-cost methods are needed to enhance various bioremediation technologies, from natural attenuation to heavily engineered remediation of subsurface hydrocarbon contamination. Many subsurface sites have insufficient quantities of nitrogen and phosphorus, resulting in poor bioactivity and increased remediation time and costs. The addition of conventional fertilizers can improve bioactivity, but often the nutrients dissolve quickly and migrate away from the contaminant zone before being utilized by the microbes. Through this project, conducted by the Energy & Environmental Research Center, polymers were developed that slowly release nitrogen and phosphorus into the subsurface. Conceptually, these polymers are designed to adhere to soil particles in the subsurface contamination zone where they slowly degrade and release nutrients over longer periods of time compared to conventional fertilizer applications. Tests conducted during this study indicate that some of the developed polymers have excellent potential to satisfy the microbial requirements for enhanced bioremediation.

TECHNICAL BASIS DOCUMENT FOR NATURAL EVENT HAZARDS (open access)

TECHNICAL BASIS DOCUMENT FOR NATURAL EVENT HAZARDS

This technical basis document was developed to support the documented safety analysis (DSA) and describes the risk binning process and the technical basis for assigning risk bins for natural event hazard (NEH)-initiated accidents. The purpose of the risk binning process is to determine the need for safety-significant structures, systems, and components (SSC) and technical safety requirement (TSR)-level controls for a given representative accident or represented hazardous conditions based on an evaluation of the frequency and consequence. Note that the risk binning process is not applied to facility workers, because all facility worker hazardous conditions are considered for safety-significant SSCs and/or TSR-level controls.

Transportation Security Administration: Oversight of Explosive Detection Systems Maintenance Contracts Can Be Strengthened (open access)

Transportation Security Administration: Oversight of Explosive Detection Systems Maintenance Contracts Can Be Strengthened

A letter report issued by the Government Accountability Office with an abstract that begins "Mandated to screen all checked baggage by using explosive detection systems at airports by December 31, 2003, the Transportation Security Administration (TSA) has deployed two types of screening equipment: explosive detection systems (EDS), which use computer-aided tomography X-rays to recognize explosives, and explosive trace detection (ETD) systems, which use chemical analysis to detect explosive residues. This report discusses (1) EDS and ETD maintenance costs, (2) factors that played a role in these costs, and (3) the extent to which TSA conducts oversight of maintenance contracts. GAO reviewed TSA's contract files and processes for reviewing contractor cost and performance data."

Treasury's Bank Enterprise Award Program: Impact on Investments in Distressed Communities Is Difficult to Determine, but Likely Not Significant (open access)

Treasury's Bank Enterprise Award Program: Impact on Investments in Distressed Communities Is Difficult to Determine, but Likely Not Significant

A letter report issued by the Government Accountability Office with an abstract that begins "Established in 1994, the Department of the Treasury's Bank Enterprise Award (BEA) program provides cash awards to banks that increase their investments in community development financial institutions (CDFI) and lending in economically distressed communities. CDFIs are specialized institutions that provide financial services to areas and populations underserved by conventional lenders and investors. In 2005, Treasury provided nearly $10 million in BEA awards. The BEA program has faced longstanding questions about its effectiveness and experienced significant declines in funding in recent years. This report (1) examines the extent to which the BEA program may have provided banks with financial incentives and (2) assesses the BEA program's performance measures and internal controls. To complete this study, GAO reviewed relevant award data; interviewed Treasury, bank, and CDFI officials; and assessed the BEA program's performance measures and internal controls against GAO's standards for effective measures and controls."

Vadose Zone Transport Field Study: Summary Report (open access)

Vadose Zone Transport Field Study: Summary Report

From FY 2000 through FY 2003, a series of vadose zone transport field experiments were conducted as part of the U.S. Department of Energy’s Groundwater/Vadose Zone Integration Project Science and Technology Project, now known as the Remediation and Closure Science Project, and managed by the Pacific Northwest National Laboratory (PNNL). The series of experiments included two major field campaigns, one at a 299-E24-11 injection test site near PUREX and a second at a clastic dike site off Army Loop Road. The goals of these experiments were to improve our understanding of vadose zone transport processes; to develop data sets to validate and calibrate vadose zone flow and transport models; and to identify advanced monitoring techniques useful for evaluating flow-and-transport mechanisms and delineating contaminant plumes in the vadose zone at the Hanford Site. This report summarizes the key findings from the field studies and demonstrates how data collected from these studies are being used to improve conceptual models and develop numerical models of flow and transport in Hanford’s vadose zone. Results of these tests have led to a better understanding of the vadose zone. Fine-scale geologic heterogeneities, including grain fabric and lamination, were observed to have a strong effect on the …

Accelerating Network Traffic Analytics Using Query-DrivenVisualization (open access)

Accelerating Network Traffic Analytics Using Query-DrivenVisualization

Realizing operational analytics solutions where large and complex data must be analyzed in a time-critical fashion entails integrating many different types of technology. This paper focuses on an interdisciplinary combination of scientific data management and visualization/analysis technologies targeted at reducing the time required for data filtering, querying, hypothesis testing and knowledge discovery in the domain of network connection data analysis. We show that use of compressed bitmap indexing can quickly answer queries in an interactive visual data analysis application, and compare its performance with two alternatives for serial and parallel filtering/querying on 2.5 billion records worth of network connection data collected over a period of 42 weeks. Our approach to visual network connection data exploration centers on two primary factors: interactive ad-hoc and multiresolution query formulation and execution over n dimensions and visual display of then-dimensional histogram results. This combination is applied in a case study to detect a distributed network scan and to then identify the set of remote hosts participating in the attack. Our approach is sufficiently general to be applied to a diverse set of data understanding problems as well as used in conjunction with a diverse set of analysis and visualization tools.

Chapter 9: Model Systems for Formation and Dissolution of Calcium Phosphate Minerals (open access)

Chapter 9: Model Systems for Formation and Dissolution of Calcium Phosphate Minerals

Calcium phosphates are the mineral component of bones and teeth. As such there is great interest in understanding the physical mechanisms that underlie their growth, dissolution, and phase stability. Control is often achieved at the cellular level by the manipulation of solution states and the use of crystal growth modulators such as peptides or other organic molecules. This chapter begins with a discussion of solution speciation in body fluids and relates this to important crystal growth parameters such as the supersaturation, pH, ionic strength and the ratio of calcium to phosphate activities. We then discuss the use of scanning probe microscopy as a tool to measure surface kinetics of mineral surfaces evolving in simplified solutions. The two primary themes that we will touch on are the use of microenvironments that temporally evolve the solution state to control growth and dissolution; and the use of various growth modifiers that interact with the solution species or with mineral surfaces to shift growth away from the lowest energy facetted forms. The study of synthetic minerals in simplified solution lays the foundation for understand mineralization process in more complex environments found in the body.
