Anaerobic Fe(III) reduction by Shewanella putrefaciens: Analysis of the electron transport chain

Description: The goals of the project were to isolate mutants that are deficient in metal reduction, identify components of the electron transport chain that are involved in this process, and purify some of these proteins for biochemical analyses. In the 3-year period since the start of the project, we have accomplished many of these goals. We have isolated several new S. oneidensis mutants that are deficient in metal reduction, and have initiated the development of vectors for the overexpression of cytochr… more

Chemical Plant Security

Description: Facilities handling large amounts of potentially hazardous chemicals (i.e., chemical facilities) might be of interest to terrorists, either as targets for direct attacks meant to release chemicals into the community or as a source of chemicals for use elsewhere. Because few terrorist attacks have been attempted against chemical facilities in the United States, the risk of death and injury in the near future is estimated to be low, relative to the likelihood of accidents at such facilities or at… more

Closed orbit response to quadrupole strength variation

Description: We derive two formulae relating the variation in closed orbit in a storage ring to variations in quadrupole strength, neglecting nonlinear and dispersive effects. These formulae correct results previously reported [1,2,3]. We compare the results of the formulae applied to the ATF with simulations using MAD, and consider their application to beam-based alignment.

HARNESS: Heterogeneous Adaptable Reconfigurable Networked Systems. Final Progress Report

Description: HARNESS was proposed as a system that combined the best of emerging technologies found in current distributed computing research and commercial products into a very flexible, dynamically adaptable framework that could be used by applications to allow them to evolve and better handle their execution environment. The HARNESS system was designed using the considerable experience from previous projects such as PVM, MPI, IceT and Cumulvs. As such, the system was designed to avoid any of the common p… more

Life-Cycle Cost Analysis of Energy Efficiency Design Options for Residential Furnaces and Boilers

Description: In 2001, the U.S. Department of Energy (DOE) initiated a rulemaking process to consider whether to amend the existing energy efficiency standards for furnaces and boilers. A key factor in DOE's consideration of new standards is the economic impacts on consumers of possible revisions to energy-efficiency standards. Determining cost-effectiveness requires an appropriate comparison of the additional first cost of energy efficiency design options with the savings in operating costs. DOE's preferred… more

Pilot-Scale Testing of a Rotary Microfilter with Irradiated Filter Disks and Simulated SRS Waste

Description: The processing rate of the Actinide Removal Project (ARP) is limited by the flow rate of the solid-liquid separation process. If the Department of Energy, DOE, could identify and develop a solid- liquid separation technology with a higher filter flux, they could increase the throughput of the Actinide Removal Project and complete treating that fraction of the waste stream in a shorter time, with a significant reduction in life-cycle cost. Savannah River Technology Center personnel identified th… more

Remote Chemical Sensing Using Quantum Cascade Lasers

Description: Research done by the IR sensors team at PNNL is focused on developing advanced spectroscopic methods for detecting signatures of nuclear, chemical, biological and explosives weapons or weapons production. The sensors we develop fall into two categories: remote sensors that can be operated at distances ranging from 150 m to 10 km, and point sensors that are used for in-situ inspection and detection. FY03 has seen an explosion in FM DIAL progress with the net result being solid confirmation that … more

Social Security: Raising or Eliminating the Taxable Earnings Base

Description: Social Security taxes are levied on earnings up to a maximum level set each year. In 2004, this maximum — or what is referred to as the taxable earnings base — is $87,900. There is no similar base for the Medicare Hospital Insurance (HI) portion of the tax; all earnings are taxable for HI purposes. Elimination of the HI base was proposed by President Clinton and enacted in 1993, effectively beginning in 1994. Recently others have proposed that the base for Social Security be raised or eliminate… more

Tax Administration: Planning for IRS's Enforcement Process Changes Included Many Key Steps but Can Be Improved

Description: A letter report issued by the General Accounting Office with an abstract that begins "In recent years, the Internal Revenue Service (IRS) has experienced declines in most of its enforcement programs, including declines in audits and in efforts to collect delinquent taxes. Increasing enforcement productivity is one strategy that can help reverse these declines. To this end, IRS is currently planning and has begun implementing enforcement process improvement projects. GAO was asked to assess the … more

Tracking the Inside Intruder Using Net Log on Debug Logging in Microsoft Windows Server Operating Systems

Description: In today's well-connected environments of the Internet, intranets, and extranets, protecting the Microsoft Windows network can be a daunting task for the security engineer. Intrusion Detection Systems are a must-have for most companies, but few have either the financial resources or the people resources to implement and maintain full-scale intrusion detection systems for their networks and hosts. Many will at least invest in intrusion detection for their Internet presence, but others have not y… more

Bringing Peace to Chechnya? Assessments and Implications

Description: Russia's then-Premier Vladimir Putin ordered military, police, and security forces to enter the breakaway Chechnya region in September 1999, and these forces occupied most of the region by early 2000. The conflict has resulted in thousands of military and civilian casualties and the massive destruction of housing and infrastructure. Putin's rise to power and continuing popularity have been tied at least partly to his perceived ability to prosecute this conflict successfully. This report detail… more
