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

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

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 cytochromes and other proteins in S. oneidensis. We have also overexpressed CymA, one of the c cytochromes that are involved in metal reduction.

Chemical Plant Security (open access)

Chemical Plant Security

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 attacks on other targets using conventional weapons. For any individual facility, the risk is very small, but risks may be increasing with potentially severe consequences for human health and the environment. Available evidence indicates that many chemical facilities may lack adequate safeguards.

Closed orbit response to quadrupole strength variation (open access)

Closed orbit response to quadrupole strength variation

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.

Failure of Vapor Overheads Discharge Line for a Radioactive Waste Evaporator (open access)

Failure of Vapor Overheads Discharge Line for a Radioactive Waste Evaporator

A 2-inch schedule 40 steel core pipe in an evaporator overheads discharge line broke at several locations downstream from a section of the line where it bridges a road. Fish mouth openings that developed along the pipe seams were initiated at lack of fusion defects in the pipe welds. A vacuum created in the piping upstream of the breaks prevented full drainage of the water upon shut down of the pump. Freezing of water in the pipe (the line was not heat traced) and water hammer effects occurring with pump restart could each contribute to the extensive deformation and tearing observed at the breaks. Both the weld flaws and the over pressure contributed to the outcome. All pipe was replaced and a vacuum break was installed to eliminate the problem.

HARNESS: Heterogeneous Adaptable Reconfigurable Networked Systems. Final Progress Report (open access)

HARNESS: Heterogeneous Adaptable Reconfigurable Networked Systems. Final Progress Report

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 problems found with using these current systems, such as no single point of failure, ability to survive machine, node and software failures. Additional features included improved intercomponent connectivity, with full support for dynamic down loading of addition components at run-time thus reducing the stress on application developers to build in all the libraries they need in advance.

Identifying performance bottlenecks on modern microarchitectures using an adaptable probe (open access)

Identifying performance bottlenecks on modern microarchitectures using an adaptable probe

The gap between peak and delivered performance for scientific applications running on microprocessor-based systems has grown considerably in recent years. The inability to achieve the desired performance even on a single processor is often attributed to an inadequate memory system, but without identification or quantification of a specific bottleneck. In this work, we use an adaptable synthetic benchmark to isolate application characteristics that cause a significant drop in performance, giving application programmers and architects information about possible optimizations. Our adaptable probe, called sqmat, uses only four parameters to capture key characteristics of scientific workloads: working-set size, computational intensity, indirection, and irregularity. This paper describes the implementation of sqmat and uses its tunable parameters to evaluate four leading 64-bit microprocessors that are popular building blocks for current high performance systems: Intel Itanium2, AMD Opteron, IBM Power3, and IBM Power4.

Life-Cycle Cost Analysis of Energy Efficiency Design Options for Residential Furnaces and Boilers (open access)

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

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 approach involves comparing the total life-cycle cost (LCC) of owning and operating a more efficient appliance with the LCC for a baseline design. This study describes the method used to conduct the LCC analysis and presents the estimated change in LCC associated with more energy-efficient equipment. The results indicate that efficiency improvement relative to the baseline design can reduce the LCC in each of the product classes considered.

The Numerical Electromagnetics Code (NEC) - A Brief History (open access)

The Numerical Electromagnetics Code (NEC) - A Brief History

The Numerical Electromagnetics Code, NEC as it is commonly known, continues to be one of the more widely used antenna modeling codes in existence. With several versions in use that reflect different levels of capability and availability, there are now 450 copies of NEC4 and 250 copies of NEC3 that have been distributed by Lawrence Livermore National Laboratory to a limited class of qualified recipients, and several hundred copies of NEC2 that had a recorded distribution by LLNL. These numbers do not account for numerous copies (perhaps 1000s) that were acquired through other means capitalizing on the open source code, the absence of distribution controls prior to NEC3 and the availability of versions on the Internet. In this paper we briefly review the history of the code that is concisely displayed in Figure 1. We will show how it capitalized on the research of prominent contributors in the early days of computational electromagnetics, how a combination of events led to the tri-service-supported code development program that ultimately led to NEC and how it evolved to the present day product. The authors apologize that space limitations do not allow us to provide a list of references or to acknowledge the numerous …

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

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

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 the rotary microfilter as a technology that could significantly increase filter flux, with improvements of as much as 10X over the 0.5 micron crossflow filter and 5X over the 0.1 micron crossflow filter. The Savannah River Technology Center received funding from the DOE-HQ, Office of Cleanup Technologies, to evaluate and develop the rotary microfilter for radioactive service at the Savannah River Site. The authors performed pilot-scale simulant filtration tests with irradiated filter disks. They employed three types of filter disks for the tests (0.5 m stainless steel, 0.1 m stainless steel, and 0.1 m ceramic/stainless steel). They analyzed the filter's structural material, Ryton(R) for hardness, and irradiated the entire disk with an estimated 2.5-5 year (83-165 MRad) radiation dose. They measured the hardness of …
