Testimony issued by the Government Accountability Office with an abstract that begins "In summary, VA’s SDVOSB program remains vulnerable to fraud and abuse. VA has made inconsistent statements about its progress in verifying firms listed in VetBiz using the new, more-thorough process the agency implemented in response to the 2010 Act. In one communication, VA stated that as of February 2011, all new verifications would use the 2010 Act process going forward. According to the most-recent information provided by VA, there are 6,079 SDVOSBs and veteran-owned small businesses (VOSB) listed in VetBiz. Of these, 3,724 were verified under the more-through process implemented under the 2010 Act, and 2,355—over 38 percent—were verified under the less-rigorous 2006 Act process. The presence of firms that have only been subjected to the less-stringent process that VA previously used represents a continuing vulnerability. In 2011, VA’s Office of Inspector General (OIG) issued a report finding that VA’s document review process under the 2006 Act “ in many cases was insufficient to establish control and ownership [and] in effect allowed businesses to self-certify as a veteran-owned or service-disabled veteran-owned small business with little supporting documentation.”"

A letter report issued by the Government Accountability Office with an abstract that begins "To help the Department of State (State) meet its requirements for critical goods and services in Iraq and Afghanistan, the Department of Defense (DOD) supported State on 22 acquisitions. On State's behalf, DOD awarded and manages 20 acquisitions, known as assisted interagency acquisitions, under the authority of the Economy Act with an estimated value of almost $1 billion for basic support goods and services and security services. DOD also supported two of State's acquisitions for medical services and unmanned aerial vehicles. Across the 22 acquisitions, DOD has been involved in one or more aspects of the acquisition cycle, including planning, award, management, and oversight. GAO identified at least 128 DOD personnel with contracting and subject matter expertise who provided support for these acquisitions."

Correspondence issued by the Government Accountability Office with an abstract that begins "Almost all ANS hardware and most software development were completed prior to its cancellation, according to the Army and GDRS. The software for the most advanced capabilities was not completed, which potentially presented the greatest complexities. GDRS had demonstrated many of ANS’s capabilities to some extent, including its capability to avoid obstacles and follow a leading vehicle through varying terrain. ANS had not yet progressed to the independent testing phase, however. In cancelling ANS and MM-UGV, the Army estimated that approximately $2.5 billion in planned funding for fiscal years 2013 to 2017 could be made available for other Army efforts. According to Army officials, the government owns the work completed on ANS to date."

Correspondence issued by the Government Accountability Office with an abstract that begins "Minority- or female-owned, minority-owned, and female-owned firms represented 15 percent, 6 percent and 10 percent, respectively, of firms in the U.S. pipeline industry in 2007. In terms of market share, minority- or female-owned firms are estimated to have accounted for a total of 13 percent of industry receipts, with minority-owned firms having accounted for 3 percent and female-owned firms having accounted for 11 percent of receipts."

A letter report issued by the Government Accountability Office with an abstract that begins "Since fiscal year 2005, the number of federal non-postal civilian and non-tactical military vehicles has increased about 7 percent, from about 420,000 to 449,000 vehicles. However, from fiscal year 2005 to 2011, some agencies decreased their fleets, and the change in fleet size from agency to agency varied considerably. For example, one-third of the agencies (8 of 24) with the largest number of vehicles decreased their fleets by at least 2 percent during this period. Of the 4 agencies GAO selected for review, the Departments of Agriculture (USDA) and Veterans Affairs (VA) increased their fleets 5 and 49 percent, respectively since fiscal year 2005; the U.S. Air Force and Department of the Interior (Interior) decreased their fleets 7 and 9 percent, respectively. Overall, federal agencies increased the portion of their fleets made up of alternative fuel vehicles (e.g., vehicles that operate using ethanol or batteries) from about 14 percent to 33 percent from fiscal years 2005 to 2011. In addition, GAO found that 8 agencies accounted for almost 80 percent of total federal vehicles in fiscal year 2011, while 35 other agencies held the remaining vehicles."

This report discusses the Sustainable Growth Rate (SGR), which is the statutory method for determining the annual updates to the Medicare physician fee schedule. The SGR system was established because of the concern that the Medicare fee schedule itself would not adequately constrain overall increases in spending for physicians’ services.

Beginning January 1, 2012, most carbon dioxide emissions from commercial flights to, from, and within the European Union are covered by the EU Emission Trading Scheme. This report details why there is a need to address aviation emissions, how the EU's emissions trading scheme works, estimated impacts on U.S. airlines, and related materials.

Indiana University’s SWIM activities have primarily been in three areas. All are completed, but we are continuing to work on two of them because refinements are useful to both DoE laboratories and the high performance computing community.

This technical report covers a 3-year cooperative agreement between the University of Maine and the Northeastern Forest Experiment Station that focused on the characterization of forest stands and the assessment of forest carbon storage (see attached for detailed description of the project). The goal of this work was to compare estimates of forest C storage made via remeasurement of FIA-type plots with eddy flux measurements. In addition to relating whole ecosystem estimates of carbon storage to changes in aboveground biomass, we explored methodologies by partitioning growth estimates from periodic inventory measurements into annual estimates. In the final year, we remeasured plots that were subject to a shelterwood harvest over the winter of 2001-02 to assess the production of coarse woody debris by this harvest, to remeasure trees in a long-term stand first established by NASA, to carry out other field activities at Howland, and, to assess the importance of downed and decaying wood as well as standing dead trees to the C inputs to harvested and non harvested plots.

This is the final technical report for the SBIR Phase I project titled 'A System for Conducting Sophisticated Mechanical Tests in Situ with High Energy Synchrotron X-Rays.' Experiments using diffraction of synchrotron radiation that help scientists understand engineering material failure modes, such as fracture and fatigue, require specialized machinery. This machinery must be able to induce these failure modes in a material specimen while adhering to strict size, weight, and geometric limitations prescribed by diffraction measurement techniques. During this Phase I project, Mechanical Solutions, Inc. (MSI) developed one such machine capable of applying uniaxial mechanical loading to a material specimen in both tension and compression, with zero backlash while transitioning between the two. Engineers currently compensate for a lack of understanding of fracture and fatigue by employing factors of safety in crucial system components. Thus, mechanical and structural parts are several times bigger, thicker, and heavier than they need to be. The scientific discoveries that result from diffraction experiments which utilize sophisticated mechanical loading devices will allow for broad material, weight, fuel, and cost savings in engineering design across all industries, while reducing the number of catastrophic failures in transportation, power generation, infrastructure, and all other engineering systems.

Forests provide wildlife habitat, water and air purification, climate moderation, and timber and nontimber products. Concern about climate change has put forests in the limelight as sinks of atmospheric carbon. The C stored in the global vegetation, mostly in forests, is nearly equivalent to the amount present in atmospheric CO{sub 2}. Both voluntary and government-mandated carbon trading markets are being developed and debated, some of which include C sequestration resulting from forest management as a possible tradeable commodity. However, uncertainties regarding sources of variation in sequestration rates, validation, and leakage remain significant challenges for devising strategies to include forest management in C markets. Hence, the need for scientifically-based information on C sequestration by forest management has never been greater. The consequences of forest management on the US carbon budget are large, because about two-thirds of the {approx}300 million hectare US forest resource is classified as 'commercial forest.' In most C accounting budgets, forest harvesting is usually considered to cause a net release of C from the terrestrial biosphere to the atmosphere. However, forest management practices could be designed to meet the multiple goals of providing wood and paper products, creating economic returns from natural resources, while sequestering C from the …

The electro-optic phase grating streak spectrometer (EOPGSS) generates a time-resolved spectra equivalent to that obtained with a conventional spectrometer/streak camera combination, but without using a streak camera (by far the more expensive and problematic component of the conventional system). The EOPGSS is based on a phase, rather than an amplitude grating. Further, this grating is fabricated of electro-optic material such as, for example, KD*P, by either etching grooves into an E-O slab, or by depositing lines of the E-O material onto an optical flat. An electric field normal to the grating alters the material’s index of refraction and thus affects a shift (in angle) of the output spectrum. Ramping the voltage streaks the spectrum correspondingly. The streak and dispersion directions are the same, so a second (static, conventional) grating disperses the spectrum in the orthogonal direction to prevent different wavelengths from “overwriting” each other. Because the streaking is done by the grating, the streaked output spectrum is recorded with a time-integrating device, such as a CCD. System model, typical design, and performance expectations will be presented.

Personnel characterized a Savannah River National Laboratory (SRNL) archived sample of Tank 48H slurry (HTF-E-05-021) in addition to the composite of samples HTF-48-12-20 and HTF-48-12-24, which were both retrieved in February 2012. The combined February 2012 sample is referred to as HTF-48-12-20/24 in this report. The results from these analyses are compared with Tank 48H samples analyzed in 2003, 2004, and 2005. This work supports the effort to demonstrate copper-catalyzed peroxide oxidation (CCPO) of organic content in this material. The principal findings with respect to the chemical and physical characteristics of the most recent sample are: (1) The measured potassium tetraphenylborate (KTPB) solid concentration is 1.76 wt %; (2) Titanium was in line with 2004 and 2005 slurry measurements at 897 mg/L, it represents 0.1535 {+-} 0.0012 wt % monosodium titanate (MST); (3) The measured insoluble solids content was 1.467 wt %; (4) The free hydroxide concentration in the Tank 48H filtrate sample (1.02 {+-} 0.02 M) is close to the Tank 48H limit (1.0 M); (5) Carbonate reported by total inorganic carbon (TIC, 1.39 {+-} 0.03 M) is more than double the concentrations measured in past (2003-2005) samples; (6) The soluble potassium content (measured at 286 {+-} 23 mg/L) …
