Transportation Security: Comprehensive Risk Assessments and Stronger Internal Controls Needed to Help Inform TSA Resource Allocation
A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) has called for using risk-informed approaches to help prioritize its investments, develop plans, and allocate resources in a way that balances security and commerce. Within DHS, the Transportation Security Administration (TSA) is responsible for making risk-informed investments to secure the transportation system. GAO evaluated to what extent TSA (1) implemented a risk management approach to inform the allocation of resources across the transportation sector and (2) followed internal control standards in its efforts to implement and use a risk management approach to inform resource allocation."

What's the Difference?--Comparing U.S. and Chinese Trade Data
This report provides a comparison of U.S. and Chinese trade data. U.S. trade with the People's Republic of China (China) is becoming increasingly contentious as the U.S. bilateral trade deficit rises. Debate over this trade deficit is hampered because of disagreement between the two countries on how large the deficit actually is. According to official U.S. figures, China has surpassed Canada as the largest supplier of U.S. imports.

Whole Building Cost and Performance Measurement: Data Collection Protocol Revision 2
This protocol was written for the Department of Energy’s Federal Energy Management Program (FEMP) to be used by the public as a tool for assessing building cost and performance measurement. The primary audiences are sustainable design professionals, asset owners, building managers, and research professionals within the Federal sector. The protocol was developed based on the need for measured performance and cost data on sustainable design projects. Historically there has not been a significant driver in the public or private sector to quantify whole building performance in comparable terms. The deployment of sustainable design into the building sector has initiated many questions on the performance and operational cost of these buildings.

Advanced Dark Energy Physics Telescope (ADEPT)
In 2006, we proposed to NASA a detailed concept study of ADEPT (the Advanced Dark Energy Physics Telescope), a potential space mission to reliably measure the time-evolution of dark energy by conducting the largest effective volume survey of the universe ever done. A peer-review panel of scientific, management, and technical experts reported back the highest possible 'excellent' rating for ADEPT. We have since made substantial advances in the scientific and technical maturity of the mission design. With this Department of Energy (DOE) award we were granted supplemental funding to support specific extended research items that were not included in the NASA proposal, many of which were intended to broadly advance future dark energy research, as laid out by the Dark Energy Task Force (DETF). The proposed work had three targets: (1) the adaptation of large-format infrared arrays to a 2 micron cut-off; (2) analytical research to improve the understanding of the dark energy figure-of- merit; and (3) extended studies of baryon acoustic oscillation systematic uncertainties. Since the actual award was only for {approx}10% of the proposed amount item (1) was dropped and item (2) work was severely restricted, consistent with the referee reviews of the proposal, although there was considerable …

Methadone-Associated Overdose Deaths: Factors Contributing to Increased Deaths and Efforts to Prevent Them
A letter report issued by the Government Accountability Office with an abstract that begins "Prescription drug abuse is a growing public health problem. In particular, methadone-associated overdose deaths--those in which methadone may have caused or contributed to the death--have risen sharply. Before the late 1990s, methadone was used mainly to treat opioid addiction but has since been increasingly prescribed to manage pain. Taken too often, in too high a dose, or with other drugs or alcohol, methadone can cause serious side effects and death. Methadone-associated overdose deaths can occur under several different scenarios, including improper dosing levels by practitioners, misuse by patients who may combine methadone with other drugs, or abuse--using the drug for nontherapeutic purposes. This report examines the regulation of methadone, factors that have contributed to the increase in methadone-associated overdose deaths, and steps taken to prevent methadone-associated overdose deaths. GAO reviewed documents, laws and regulations, data, and research from relevant state and federal agencies, including the Drug Enforcement Administration (DEA) and the Substance Abuse and Mental Health Services Administration (SAMHSA). GAO also interviewed federal officials, officials in five selected states, officials from professional associations and advocacy groups, and experts in pain management, addiction treatment, and forensic sciences."

Silicon Carbide Ceramics for Compact Heat Exchangers
Silicon carbide (SiC) materials are prime candidates for high temperature heat exchangers for next generation nuclear reactors due to their refractory nature and high thermal conductivity at elevated temperatures. This research has focused on demonstrating the potential of liquid silicon infiltration (LSI) for making SiC to achieve this goal. The major advantage of this method over other ceramic processing techniques is the enhanced capability of making high dense, high purity SiC materials in complex net shapes. For successful formation of net shape SiC using LSI techniques, the carbon preform reactivity and pore structure must be controlled to allow the complete infiltration of the porous carbon structure which allows complete conversion of the carbon to SiC. We have established a procedure for achieving desirable carbon properties by using carbon precursors consisting of two readily available high purity organic materials, crystalline cellulose and phenolic resin. Phenolic resin yields a glassy carbon with low chemical reactivity and porosity while the cellulose carbon is highly reactive and porous. By adjusting the ratio of these two materials in the precursor mixtures, the properties of the carbons produced can be controlled. We have identified the most favorable carbon precursor composition to be a cellulose resin mass …

Study of Turbulent Fluctuations Driven by the Electron Temperature Gradient in the National Spherical Torus Experiment
Various theories and numerical simulations support the conjecture that the ubiquitous problem of anomalous electron transport in tokamaks may arise from a short-scale turbulence driven by the electron temperature gradient. To check whether this turbulence is present in plasmas of the National Spherical Torus Experiment (NSTX), measurements of turbulent fluctuations were performed with coherent scattering of electromagnetic waves. Results from plasmas heated by high harmonic fast waves (HHFW) show the existence of density fluctuations in the range of wave numbers k⊥ρe=0.1-0.4, corresponding to a turbulence scale length of the order of the collisionless skin depth. Experimental observations and agreement with numerical results from the linear gyro-kinetic GS2 code indicate that the observed turbulence is driven by the electron temperature gradient. These turbulent fluctuations were not observed at the location of an internal transport barrier driven by a negative magnetic shear.

Department of Defense: Additional Actions and Data Are Needed to Effectively Manage and Oversee DOD's Acquisition Workforce
A letter report issued by the Government Accountability Office with an abstract that begins "Since 2001, the Department of Defense's (DOD) spending on goods and services has more than doubled to $388 billion in 2008, while the number of civilian and military acquisition personnel has remained relatively stable. To augment its in-house workforce, DOD relies heavily on contractor personnel. If it does not maintain an adequate workforce, DOD places its billion-dollar acquisitions at an increased risk of poor outcomes and vulnerability to fraud, waste, and abuse. GAO was asked to (1) assess DOD's ability to determine whether it has a sufficient acquisition workforce, (2) assess DOD initiatives to improve the management and oversight of its acquisition workforce, and (3) discuss practices of leading organizations that could provide insights for DOD's acquisition workforce oversight. To do this, GAO analyzed key DOD studies, obtained data from 66 major weapon system program offices across DOD, and interviewed officials from 4 program offices. GAO also met with representatives from six companies recognized as leaders in workforce management."

Deposition Velocities of Newtonian and Non-Newtonian Slurries in Pipelines
The WTP pipe plugging issue, as stated by the External Flowsheet Review Team (EFRT) Executive Summary, is as follows: “Piping that transports slurries will plug unless it is properly designed to minimize this risk. This design approach has not been followed consistently, which will lead to frequent shutdowns due to line plugging.” A strategy was employed to perform critical-velocity tests on several physical simulants. Critical velocity is defined as the point where a stationary bed of particles deposits on the bottom of a straight horizontal pipe during slurry transport operations. Results from the critical velocity testing provide an indication of slurry stability as a function of fluid rheological properties and transport conditions. The experimental results are compared to the WTP design guide on slurry transport velocity in an effort to confirm minimum waste velocity and flushing velocity requirements as established by calculations and critical line velocity correlations in the design guide. The major findings of this testing is discussed below. Experimental results indicate that the use of the Oroskar and Turian (1980) correlation in the design guide is conservative—Slurry viscosity has a greater affect on particles with a large surface area to mass ratio. The increased viscous forces on these …

Federal Student Aid: Recent Changes to Eligibility Requirements and Additional Efforts to Promote Awarness Could Increase Academic Competitiveness and SMART Grant Participation
A letter report issued by the Government Accountability Office with an abstract that begins "The Academic Competitiveness (AC) and National Science and Mathematics Access to Retain Talent (SMART) Grants were established by the Deficit Reduction Act of 2005. The grants provide merit-based financial aid to certain low-income college students eligible for Federal Pell Grants and are administered by the Department of Education (Education). In the first year of implementation, participation was lower than expected. GAO was asked to determine (1) factors affecting AC and SMART Grant student participation; (2) challenges colleges face in administering the grant programs; and (3) the extent to which Education has assisted states and colleges with implementation. To address these objectives, GAO analyzed data on AC, SMART, and Pell Grants, and interviewed officials from Education and 12 state education agencies, administrators from 42 selected colleges, and several national associations."
