Advanced Process Heater (open access)

Advanced Process Heater

The Roadmap for Process Heating Technology (March 16, 2001), identified the following priority R&D needs: Improved performance of high temperature materials; Improved methods for stabilizing low emission flames; Heating technologies that simultaneously reduce emissions, increase efficiency, and increase heat transfer. This Category I award entitled ''Proof of Concept of an Advanced Process Heater (APH) for Steel, Aluminum, and Petroleum Industries of the Future'' met the technical feasibility goals of: (1) Doubling the heat transfer rates (2) Improving thermal efficiencies by 20%, (3) Improving temperature uniformity by 100 degrees F and (4) simultaneously reducing NOx and CO2 emissions. The APH address EERE's mission priority of increasing efficiency/reducing fuel usage in energy intensive industries. One component of the APH, the SpyroCorTM, was commercialized by STORM Development's partner, Spinworks LLC. Over 2000 SpyrCorsTM were sold in 2004 resulting in 480 million BTU's of energy savings, 20% reduction in NOx and CO2 levels, and 9 jobs in N.W. Pennsylvania. A second component, the HeatCorTM, a low-cost high-temperature heat exchanger will be demonstrated by Spinworks in 2005 in preparation for commercial sales in 2006. The project occurred in the 21st Congressional District of Pennsylvania. Once fully commercialized, the APH energy savings potential is 339 trillion …

Agricultural Biotechnology: Background and Recent Issues (open access)

Agricultural Biotechnology: Background and Recent Issues

Since the first genetically engineered (GE) crops (also called GM [genetically modified] crops, or GMOs, genetically modified organisms) became commercially available in the mid-1990s, U.S. soybean, cotton, and corn farmers have rapidly adopted them. As adoption has spread, there have been policy debates over the costs and benefits of GE products. Issues include the impacts of GE crops on the environment and food safety, and whether GE foods should be specially labeled. Congress generally has been supportive of GE agricultural products, although some Members have expressed wariness about their adoption and regulation. The 109th Congress will likely continue to follow trade developments, particularly the U.S.-EU dispute, as well as U.S. regulatory mechanisms for approving biotech foods.

Antimicrobial Properties of Diamondlike Carbon-Silver-Platinum Nanocomposite Thin Films (open access)

Antimicrobial Properties of Diamondlike Carbon-Silver-Platinum Nanocomposite Thin Films

Silver and platinum were incorporated within diamondlike carbon (DLC) thin films using a multicomponent target pulsed laser deposition process. Transmission electron microscopy of the DLC-silver and DLC-platinum composite films reveals that the metals self-assemble into particulate nanocomposite structures. Nanoindentation testing has shown that diamondlike carbon-silver films exhibit hardness and Young's modulus values of approximately 37 GPa and 333 GPa, respectively. DLC-silver-platinum films exhibited antimicrobial properties against Staphylococcus bacteria. Diamondlike carbon-biofunctional metal nanocomposite films have a variety of potential medical and antimicrobial applications.

Characterization of Microbial Communities in TCE-Contaminated Seep Zone Sediments (open access)

Characterization of Microbial Communities in TCE-Contaminated Seep Zone Sediments

Hundreds of sites across the United States contain trichloroethene (TCE) contamination, including the Department of Energy's Savannah River Site (SRS) in Aiken, South Carolina. Previous studies have indicated that microorganisms are capable of efficiently degrading TCE to nonhazardous end products. In this project, molecular and growth based methods were used for microbial characterization of a TCE impacted seepzone where TCE degradation is naturally occurring. The results from this work provide clear evidence that the SRB may play a significant role in TCE degradation along the Twin Lakes seepline.

Cloture: Its Effect on Senate Proceedings

Cloture is the only means by which the Senate can vote to limit debate on a matter, and thereby overcome a possible filibuster. Until 1949, cloture could not be invoked on nominations, and before 1980 this action was attempted only twice. From 1949 through 2002, cloture was sought on 35 nominations, and invoked on 21.

Color and Variability Characteristics of Point Sources in the Faint Sky Variability Survey (open access)

Color and Variability Characteristics of Point Sources in the Faint Sky Variability Survey

The authors present an analysis of the color and variability characteristics for point sources in the Faint Sky Variability Survey (FSVS). The FSVS cataloged {approx} 23 square degrees in BVI filters from {approx} 16-24 mag to investigate variability in faint sources at moderate to high Galactic latitudes. Point source completeness is found to be >83% for a selected representative sample (V - 17.5-22.0 mag, B-V = 0.0-1.5) containing both photometric B, V detections and 80% of the time-sampled V data available compared to a basic internal source completeness of 99%. Multi-epoch (10-30) observations in V spanning minutes to years modeled by light curve simulations reveal amplitude sensitivities to {approx} 0.015-0.075 mag over a representative V = 18-22 mag range. Periodicity determinations appear viable to time-scales of an order 1 day or less using the most sampled fields ({approx} 30 epochs). The fraction of point sources is found to be generally variable at 5-8% over V = 17.5-22.0 mag. For V brighter than 19 mag, the variable population is dominated by low amplitude (< 0.05 mag) and blue (B-V < 0.35) sources, possibly representing a population of {gamma} Doradus stars. Overall, the dominant population of variable sources are bluer than B-V …

Delta/Alpha-Prime Phase Transformations in a Pu-Ga Alloy (open access)

Delta/Alpha-Prime Phase Transformations in a Pu-Ga Alloy

In pure plutonium, the monoclinic {alpha} phase is the equilibrium phase at ambient temperature and pressure. The addition of a few percent of gallium, however, allows the fcc {delta} phase to be retained metastablely at ambient conditions. When the metastable {delta} phase is cooled to subambient temperatures, it partially transforms to the monoclinic {alpha}' phase, which has gallium supersaturated in the lattice. The {alpha}' phase reverts to the {delta} phase when the sample is heated above the ambient temperature. The martensite burst (M{sub b}) and reversion start (R{sub s}) temperatures are functions of the composition, heating rate, and prior thermal history. For a Pu-2.0 at% Ga alloy, the transformation hysteresis is approximately 150 C, which is large compared with other solid-solid phase transformations. Both the forward and reverse transformations are martensitic and proceed via a burst mode. Here, we use differential scanning calorimetry (DSC) and resistometry to perform fundamental studies of the {alpha}'/{delta} transformations with the goal of understanding how aging may affect {delta} phase stability, particularly the M{sub b} temperature. Because materials properties of the {alpha}' and {delta} phases are considerably different (including a density increase of 25% and an accompanying resistivity increase of 46% upon transformation from {delta} …

European Union Enlargement (open access)

European Union Enlargement

On May 1, 2004, 10 states joined the European Union (EU), enlarging the Union to 25 members. The EU views the enlargement process as an historic opportunity to promote stability in Europe and further the integration of the continent by peaceful means. In addition to the 10 new members (Cyprus, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia, and Slovenia), three other states — Bulgaria, Romania, and Croatia — hope to accede to the EU by 2007. Turkey is also a candidate and is expected to begin accession negotiations in 2005. Macedonia has also applied for EU membership.

The European Union in 2005 and Beyond (open access)

The European Union in 2005 and Beyond

The European Union (EU) experienced significant changes in 2004 as it enlarged from 15 to 25 members and continued work on a new constitutional treaty to institute internal reforms and further EU political integration. In 2005, the EU is expected to build on these efforts and seek to implement several recent foreign policy and defense initiatives. This report describes the current status of the EU’s “constitution,” EU enlargement, the EU’s evolving foreign and defense policies, and possible implications for U.S.-EU relations.

The European Union's "Constitution" (open access)

The European Union's "Constitution"

In June 2004, the European Union (EU) concluded work on a constitutional treaty that contains changes to the EU’s governing institutions and decision-making processes. This new “constitution” grew out of the 2002-2003 Convention on the Future of Europe and previous EU efforts to institute internal reforms ahead of the Union’s expansion from 15 members to 25 in May 2004. The “constitution” aims to enable a larger EU to operate effectively and prevent gridlock, but it must still be ratified by all member states before it enters into force. This report provides background information on the Convention and describes the EU “constitution,” its key provisions, next steps, and possible implications for the U.S.-EU relationship.

Historical Doses from Tritiated Water and Tritiated Hydrogen Gas Released to the Atmosphere from Lawrence Livermore National Laboratory (LLNL). Part 2. LLNL Annual Site-specific Data, 1953 - 2003 (open access)

Historical Doses from Tritiated Water and Tritiated Hydrogen Gas Released to the Atmosphere from Lawrence Livermore National Laboratory (LLNL). Part 2. LLNL Annual Site-specific Data, 1953 - 2003

It is planned to use the tritium dose model, DCART (Doses from Chronic Atmospheric Releases of Tritium), to reconstruct dose to the hypothetical maximally exposed individual from annual routine releases of tritiated water (HTO) and tritiated hydrogen gas (HT) from all Lawrence Livermore National Laboratory (LLNL) facilities and from the Sandia National (SNL) Laboratory's Tritium Research Laboratory over the last fifty years. DCART has been described in Part 1 of ''Historical Doses From Tritiated Water And Tritiated Hydrogen Gas Released To The Atmosphere from Lawrence Livermore National Laboratory (LLNL)'' (UCRL-TR-205083). This report (Part 2) summarizes information about annual routine releases of tritium from LLNL (and SNL) since 1953. Historical records were used to derive facility-specific annual data (e.g., source terms, dilution factors, ambient air concentrations, meteorological data, including absolute humidity and rainfall, etc.) and their associated uncertainty distributions. These data will be used as input to DCART to calculate annual dose for each year of LLNL operations. Sources of information are carefully referenced, and assumptions are documented. Confidence on all data post-1974 is quite high. Prior to that, further adjustment to the estimated uncertainty may have to be made if more information comes to light.
