Global War on Terrorism: Reported Obligations for the Department of Defense (open access)

Global War on Terrorism: Reported Obligations for the Department of Defense

Correspondence issued by the Government Accountability Office with an abstract that begins "Since 2001, Congress has provided the Department of Defense (DOD) with about $808 billion in supplemental and annual appropriations, as of March 2009, primarily for military operations in support of the Global War on Terrorism (GWOT). DOD's reported annual obligations for GWOT have shown a steady increase from about $0.2 billion in fiscal year 2001 to about $162.4 billion in fiscal year 2008. For fiscal year 2009, Congress provided DOD with about $65.9 billion in supplemental appropriations for GWOT as of March 2009 and the President plans on requesting an additional $75.5 billion in supplemental appropriations for GWOT for the remainder of the fiscal year. A total of $31.0 billion has been obligated in the first quarter of fiscal year 2009 through December 2008. The United States' commitments to GWOT will likely involve the continued investment of significant resources, requiring decision makers to consider difficult trade-offs as the nation faces an increasing long-range fiscal challenge. The magnitude of future costs will depend on several direct and indirect cost variables and, in some cases, decisions that have not yet been made. DOD's future costs will likely be affected by …

Defense Infrastructure: DOD Needs to Periodically Review Support Standards and Costs at Joint Bases and Better Inform Congress of Facility Sustainment Funding Uses

A letter report issued by the Government Accountability Office with an abstract that begins "The 2005 Defense Base Closure and Realignment Commission recommended that the Department of Defense (DOD) establish 12 joint bases by consolidating the management and support of 26 separate installations, potentially saving $2.3 billion over 20 years. In response to a direction from the House Armed Services Committee report accompanying the National Defense Authorization Act for Fiscal Year 2009, GAO evaluated DOD's (1) efforts and expected costs to deliver installation support at joint bases and (2) funding for facility sustainment, which includes the maintenance and repair activities necessary to keep facilities in good working order, at all installations. GAO compared new support standards with the current support levels, visited nine installations that will become four joint bases, and compared facility sustainment funding levels with requirements and goals."

Defined Benefit Pensions: Survey Results of the Nation's Largest Private Defined Benefit Plan Sponsors (open access)

Defined Benefit Pensions: Survey Results of the Nation's Largest Private Defined Benefit Plan Sponsors

A letter report issued by the Government Accountability Office with an abstract that begins "The number of private defined benefit (DB) pension plans, an important source of retirement income for millions of Americans, has declined substantially over the past two decades. For example, about 92,000 single-employer DB plans existed in 1990, compared to just under 29,000 single-employer plans today. Although this decline has been concentrated among smaller plans, there is a widespread concern that large DB plans covering many participants have modified, reduced, or otherwise frozen plan benefits in recent years. GAO was asked to examine (1) what changes employers have made to their pension and benefit offerings, including to their defined contribution (DC) plans and health offerings over the last 10 years or so, and (2) what changes employers might make with respect to their pensions in the future, and how these changes might be influenced by changes in pension law and other factors. To gather information about overall changes in pension and health benefit offerings, GAO asked 94 of the nation's largest DB plan sponsors to participate in a survey; 44 of these sponsors responded. These respondents represent about one-quarter of the total liabilities in the nation's single-employer …

Defense Acquisitions: Assessments of Selected Weapon Programs

A letter report issued by the Government Accountability Office with an abstract that begins "This is GAO's seventh annual assessment of selected Department of Defense (DOD) weapon programs. The report examines how well DOD is planning and executing its weapon acquisition programs, an area that has been on GAO's high-risk list since 1990. This year's report is in response to the mandate in the joint explanatory statement to the Consolidated Security, Disaster Assistance, and Continuing Appropriations Act, 2009. The report includes (1) an analysis of the overall performance of DOD's 2008 portfolio of 96 major defense acquisition programs and a comparison to the portfolio performance at two other points in time--5 years ago and 1 year ago; (2) an analysis of current cost and schedule outcomes and knowledge attained by key junctures in the acquisition process for a subset of 47 weapon programs--primarily in development--from the 2008 portfolio; (3) data on other factors that could impact program stability; and (4) an update on changes in DOD's acquisition policies. To conduct our assessment, GAO analyzed cost, schedule, and quantity data from DOD's Selected Acquisition Reports for the programs in DOD's 2003, 2007, and 2008 portfolios. GAO also collected data from program …

Low Temperature Combustion with Thermo-Chemical Recuperation to Maximize In-Use Engine Efficiency (open access)

Low Temperature Combustion with Thermo-Chemical Recuperation to Maximize In-Use Engine Efficiency

The key to overcome Low Temperature Combustion (LTC) load range limitations in reciprocating engines is based on proper control over the thermo-chemical properties of the in-cylinder charge. The studied alternative to achieve the required control of LTC is the use of two separate fuel streams to regulate timing and heat release at specific operational points, where the secondary fuel is a reformed product of the primary fuel in the tank. It is proposed in this report that the secondary fuel can be produced using exhaust heat and Thermo-Chemical Recuperation (TCR). TCR for reciprocating engines is a system that employs high efficiency recovery of sensible heat from engine exhaust gas and uses this energy to transform fuel composition. The recuperated sensible heat is returned to the engine as chemical energy. Chemical conversions are accomplished through catalytic and endothermic reactions in a specially designed reforming reactor. An equilibrium model developed by Gas Technology Institute (GTI) for heptane steam reforming was applied to estimate reformed fuel composition at different reforming temperatures. Laboratory results, at a steam/heptane mole ratio less than 2:1, confirm that low temperature reforming reactions, in the range of 550 K to 650 K, can produce 10-30% hydrogen (by volume, wet) …

Observations on Faults and Associated Permeability Structures in Hydrogeologic Units at the Nevada Test Site (open access)

Observations on Faults and Associated Permeability Structures in Hydrogeologic Units at the Nevada Test Site

Observational data on Nevada Test Site (NTS) faults were gathered from a variety of sources, including surface and tunnel exposures, core samples, geophysical logs, and down-hole cameras. These data show that NTS fault characteristics and fault zone permeability structures are similar to those of faults studied in other regions. Faults at the NTS form complex and heterogeneous fault zones with flow properties that vary in both space and time. Flow property variability within fault zones can be broken down into four major components that allow for the development of a simplified, first approximation model of NTS fault zones. This conceptual model can be used as a general guide during development and evaluation of groundwater flow and contaminate transport models at the NTS.

Looking for Darwin's footprints in the microbial world (open access)

Looking for Darwin's footprints in the microbial world

As we observe the 200th anniversary of Charles Darwin's birthday, microbiologists interested in the application of Darwin's ideas to the microscopic world have a lot to celebrate: an emerging picture of the (mostly microbial) Tree of Life at ever-increasing resolution, an understanding of horizontal gene transfer as a driving force in the evolution of microbes, and thousands of complete genome sequences to help formulate and refine our theories. At the same time, quantitative models of the microevolutionary processes shaping microbial populations remain just out of reach, a point that is perhaps most dramatically illustrated by the lack of consensus on how (or even whether) to define bacterial species. We summarize progress and prospects in bacterial population genetics, with an emphasis on detecting the footprint of positive Darwinian selection in microbial genomes.

Pyramidal and Chiral Groupings of Gold Nanocrystals Assembled Using DNA Scaffolds (open access)

Pyramidal and Chiral Groupings of Gold Nanocrystals Assembled Using DNA Scaffolds

Nanostructures constructed from metal and semiconductor nanocrystals conjugated to, and organized by DNA are an emerging class of material with collective optical properties. We created discrete pyramids of DNA with gold nanocrystals at the tips. By taking small angle X-ray scattering (SAXS) measurments from solutions of these pyramids we confirmed that this pyramidal geometry creates structures which are more rigid in solution than linear DNA. We then took advantage of the tetrahedral symmetry to demonstrate construction of chiral nanostructures.

Melt spreading code assessment, modifications, and application to the EPR core catcher design. (open access)

Melt spreading code assessment, modifications, and application to the EPR core catcher design.

The Evolutionary Power Reactor (EPR) is under consideration by various utilities in the United States to provide base load electrical production, and as a result the design is undergoing a certification review by the U.S. Nuclear Regulatory Commission (NRC). The severe accident design philosophy for this reactor is based upon the fact that the projected power rating results in a narrow margin for in-vessel melt retention by external cooling of the reactor vessel. As a result, the design addresses ex-vessel core melt stabilization using a mitigation strategy that includes: (1) an external core melt retention system to temporarily hold core melt released from the vessel; (2) a layer of 'sacrificial' material that is admixed with the melt while in the core melt retention system; (3) a melt plug in the lower part of the retention system that, when failed, provides a pathway for the mixture to spread to a large core spreading chamber; and finally, (4) cooling and stabilization of the spread melt by controlled top and bottom flooding. The overall concept is illustrated in Figure 1.1. The melt spreading process relies heavily on inertial flow of a low-viscosity admixed melt to a segmented spreading chamber, and assumes that the …

Solving large-scale sparse eigenvalue problems and linear systems of equations for accelerator modeling (open access)

Solving large-scale sparse eigenvalue problems and linear systems of equations for accelerator modeling

The solutions of sparse eigenvalue problems and linear systems constitute one of the key computational kernels in the discretization of partial differential equations for the modeling of linear accelerators. The computational challenges faced by existing techniques for solving those sparse eigenvalue problems and linear systems call for continuing research to improve on the algorithms so that ever increasing problem size as required by the physics application can be tackled. Under the support of this award, the filter algorithm for solving large sparse eigenvalue problems was developed at Stanford to address the computational difficulties in the previous methods with the goal to enable accelerator simulations on then the world largest unclassified supercomputer at NERSC for this class of problems. Specifically, a new method, the Hemitian skew-Hemitian splitting method, was proposed and researched as an improved method for solving linear systems with non-Hermitian positive definite and semidefinite matrices.

Real-Time Gene Expression Profiling of Live Shewanella Oneidensis Cells (open access)

Real-Time Gene Expression Profiling of Live Shewanella Oneidensis Cells

The overall objective of this proposal is to make real-time observations of gene expression in live Shewanella oneidensis cells with high sensitivity and high throughput. Gene expression, a central process to all life, is stochastic because most genes often exist in one or two copies per cell. Although the central dogma of molecular biology has been proven beyond doubt, due to insufficient sensitivity, stochastic protein production has not been visualized in real time in an individual cell at the single-molecule level. We report the first direct observation of single protein molecules as they are generated, one at a time in a single live E. coli cell, yielding quantitative information about gene expression [Science 2006; 311: 1600-1603]. We demonstrated a general strategy for live-cell single-molecule measurements: detection by localization. It is difficult to detect single fluorescence protein molecules inside cytoplasm - their fluorescence is spread by fast diffusion to the entire cell and overwhelmed by the strong autofluorescence. We achieved single-molecule sensitivity by immobilizing the fluorescence protein on the cell membrane, where the diffusion is much slowed. We learned that under the repressed condition protein molecules are produced in bursts, with each burst originating from a stochastically-transcribed single messenger RNA molecule, …

Stress- and Chemistry-Mediated Permeability Enhancement/Degradation in Stimulated Critically-Stressed Fractures (open access)

Stress- and Chemistry-Mediated Permeability Enhancement/Degradation in Stimulated Critically-Stressed Fractures

This work has investigated the interactions between stress and chemistry in controlling the evolution of permeability in stimulated fractured reservoirs through an integrated program of experimentation and modeling. Flow-through experiments on natural and artificial fractures in Coso diorite have examined the evolution of permeability under paths of mean and deviatoric stresses, including the role of dissolution and precipitation. Models accommodating these behaviors have examined the importance of incorporating the complex couplings between stress and chemistry in examining the evolution of permeability in EGS reservoirs. This document reports the findings of experiment [1,2] and analysis [3,4], in four sequential chapters.

Water Quality Trends in the Entiat River Subbasin: Final 2008 Annual Report. (open access)

Water Quality Trends in the Entiat River Subbasin: Final 2008 Annual Report.

The ISEMP program monitors the status and trend of water quality elements that may affect restoration project effectiveness in the Entiat subbasin. As part of this effort, the PNW Research Station (PNW) measures, analyzes and interprets temporal trends in natural stream water pH, dissolved oxygen, specific conductivity and temperature. The Entiat River is currently on the Clean Water Act 303(d) list for pH exceedence, and there is insufficient information to determine the spatial and temporal extent or potential causes of this exceedence. In the spring 2008, PNW redeployed data-logging, multiparameter probes at four locations in the Entiat subbasin to measure water quality parameters, focusing on pH. This resumed previous data collection that was interrupted by river ice in early December 2007. Instruments were again removed from the river in early December 2008. This annual report covers the period from December 2007 through December 2008. The highest pH values occurred during the low-flow period from midsummer through the following midspring then dropped sharply during the annual snowmelt runoff period from late spring through early summer. Water temperature began rapidly increasing during the receding limb of the annual snowmelt hydrograph. Highest mean monthly temperatures occurred in July and August, while instantaneous maxima …

Ion Uptake Determination of Dendrochronologically-Dated Trees Using Neutron Activation Analysis (open access)

Ion Uptake Determination of Dendrochronologically-Dated Trees Using Neutron Activation Analysis

Uptake of metal ions by plan roots is a function of the type and concentration of metal in the soil, the nutrient biochemistry of the plant, and the immediate environment of the root. Uptake of gold (Au) is known to be sensitive to soil pH for many species. Soil acidification due to acid precipitation following volcanic eruptions can dramatically increase Au uptake by trees. Identification of high Au content in tree rings in dendrochronologically-dated, overlapping sequences of trees allows the identification of temporally-conscribed, volcanically-influenced periods of environmental change. Ion uptake, specifically determination of trace amounts of gold, was performed for dendrochronologically-dated tree samples utilizing Neutron Activation Analysis (NAA) technique. The concentration of gold was correlated with known enviironmental changes, e.g. volcanic activities, during historic periods.

Wind Generation Feasibility Warm Springs Power and Water Enterprises (WSPWE) is a corporate entity owned by the Confederated Tribes of the Warm Springs Reservation, located in central Oregon. The organization is responsible for managing electrical power generation facilities on tribal lands and, as part of its charter, has the responsibility to evaluate and develop renewable energy resources for the Confederated Tribes of Warm Springs. WSPWE recently completed a multi-year-year wind resource assessment of tribal lands, beginning with the installation of wind monitoring towers on the Mutton Mountains site in 2003, and collection of on-site wind data is ongoing. The study identified the Mutton Mountain site on the northeastern edge of the reservation as a site with sufficient wind resources to support a commercial power project estimated to generate over 226,000 MWh per year. Initial estimates indicate that the first phase of the project would be approximately 79.5 MW of installed capacity. This Phase 2 study expands and builds on the previously conducted Phase 1 Wind Resource Assessment, dated June 30, 2007. In order to fully assess the economic benefits that may accrue to the Tribes through wind energy development at Mutton Mountain, a planning-level opinion of probable cost was performed …
