This report provides an overview of current and proposed laws at the state and federal levels that require the disclosure of the chemicals added to the fluid used in hydraulic fracturing.

This report discusses factors suggesting an increased risk of a double-dip recession. A double-dip or W-shaped recession occurs when the economy emerges from a recession, has a short period of growth, but then, still well short of a full recovery, falls back into recession. It also discusses other factors that suggest economic recovery will continue. It presents the U.S. historical experience with double-dip recessions. It examines the role of deleveraging by households and businesses in the aftermath of the recent financial crisis in shaping the likely pace of economic recovery. The report concludes with a look at current economic projections.

Testimony issued by the Government Accountability Office with an abstract that begins "In summary, TSA has completed its initial testing of the CAT/BPSS technology and has begun operational testing at three airports. We found the project’s associated life cycle cost estimate to be reasonably comprehensive and well documented, although we are less confident in its accuracy due to questions about the assumed inflation rate. In addition, we could not evaluate its credibility because the current version does not include an independent cost estimate or an assessment of how changing key assumptions and other factors would affect the estimate. Our past work has identified three key challenges related to TSA’s efforts to acquire and deploy technologies to address homeland security needs: (1) developing and meeting technology program requirements, (2) overseeing and conducting testing of new screening technologies, and (3) developing acquisition program baselines to establish initial cost, schedule, and performance parameters."

A letter report issued by the Government Accountability Office with an abstract that begins "The Social Security Administration (SSA) has taken steps that hold promise for improving the process for updating its medical criteria, but continues to face challenges ensuring timely updates. SSA now uses a two-tiered system for ongoing revisions to its medical listings. First, it completes a comprehensive review of all medical conditions listed within each of 14 body systems, making needed revisions. For subsequent updates for a body system, the agency uses a targeted approach, selecting for review and revision only those medical conditions most in need of change. To date, SSA has completed comprehensive revisions for 8 of the 14 body systems and now is reviewing conditions under them to determine where targeted revisions are appropriate. However, some of these targeted revisions have experienced delays. Moreover, SSA has yet to complete comprehensive revisions for six body systems that have been ongoing for 19 to 33 years. SSA officials attributed delays to a lack of staff and expertise, along with the complexity and unpredictability of the regulatory process."

A letter report issued by the Government Accountability Office with an abstract that begins "GAO’s analysis of Marine Corps depot maintenance activity group (DMAG) reports showed that from fiscal years 2004 through 2011, reported actual carryover exceeded the allowable amounts in the most recent 6 years of the 8- year period, ranging from $59 million in fiscal year 2007 to $7 million in fiscal year 2011. GAO’s analysis also showed that the amounts of carryover exceeding the allowable amounts have declined in each of the past 4 years. These reductions could be attributed to DMAG actions, including implementing production efficiencies that reduced the time required to repair weapon systems."

The closure of Tank 16H will require removal of material from the annulus of the tank. Samples from Tank 16H annulus were characterized and tested to provide information to evaluate various alternatives for removing the annulus waste. The analysis found all four annulus samples to be composed mainly of Si, Na, and Al and lesser amounts of other elements. The XRD data indicate quartz (SiO{sub 2}) and sodium aluminum nitrate silicate hydrate (Na{sub 8}(Al{sub 6}Si{sub 6}O{sub 24})(NO{sub 3}){sub 2}.4H{sub 2}O) as the predominant crystalline mineral phases in the samples. The XRD data also indicate the presence of crystalline sodium nitrate (NaNO{sub 3}), sodium nitrite (NaNO{sub 2}), gibbsite (Al(OH){sub 3}), hydrated sodium bicarbonate (Na{sub 3}H(CO{sub 3}){sub 2}.2H{sub 2}O), and muscovite (KAl{sub 2}(AlSi{sub 3}O{sub 10})(OH){sub 2}). Based on the weight of solids remaining at the end of the test, the water leaching test results indicate 20-35% of the solids dissolved after three contacts with an approximately 3:1 volume of water at 45 C. The chemical analysis of the leachates and the XRD results of the remaining solids indicate sodium salts of nitrate, nitrite, sulfate, and possibly carbonate/bicarbonate make up the majority of the dissolved material. The majority of these salts were dissolved …

Subcritical transition to turbulence has been proposed as a source of turbulent viscosity required for the associated angular momentum transport for fast accretion in Keplerian disks. Previously cited laboratory experiments in supporting this hypothesis were performed either in a di erent type of flow than Keplerian or without quantitative measurements of angular momentum transport and mean flow profile, and all of them appear to su er from Ekman e ects, secondary flows induced by nonoptimal axial boundary conditions. Such Ekman e ects are expected to be absent from astronomical disks, which probably have stress-free vertical boundaries unless strongly magnetized. Aims. To quantify angular momentum transport due to subcritical hydrodynamic turbulence, if exists, in a quasi-Keplerian flow with minimized Ekman e ects. Methods.We perform a local measurement of the azimuthal-radial component of the Reynolds stress tensor in a novel laboratory apparatus where Ekman e ects are minimized by flexible control of axial boundary conditions. Results.We find significant Ekman e ects on angular momentum transport due to nonoptimal axial boundary conditions in quasi-Keplerian flows. With the optimal control of Ekman e ects, no statistically meaningful angular momentum transport is detected in such flows at Reynolds number up to two millions. Conclusions. Either …

The U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office operates the Nevada National Security Site (NNSS) and North Las Vegas Facility (NLVF). From 1951 through 1992, the NNSS was the continental testing location for U.S. nuclear weapons. The release of radionuclides from NNSS activities has been monitored since the initiation of atmospheric testing. Limitation to underground detonations after 1962 greatly reduced radiation exposure to the public surrounding the NNSS. After nuclear testing ended in 1992, NNSS radiation monitoring focused on detecting airborne radionuclides from historically contaminated soils. These radionuclides are derived from re-suspension of soil (primarily by wind) and emission of tritium-contaminated soil moisture through evapotranspiration. Low amounts of legacy-related tritium are also emitted to air at the NLVF, an NNSS support complex in North Las Vegas. To protect the public from harmful levels of man-made radiation, the Clean Air Act, National Emission Standards for Hazardous Air Pollutants (NESHAP) (Title 40 Code of Federal Regulations [CFR] Part 61 Subpart H) limits the release of radioactivity from a U.S. Department of Energy (DOE) facility to that which would cause 10 millirem per year (mrem/yr) effective dose equivalent to any member of the public. This limit does not include …

The objectives of this project are to create jobs and to provide tribal homes and buildings with weatherization assistance for energy efficiency. The project will establish a Tribal Multi-County Weatherization Energy Program to provide training, outreach and education on energy assistance and conservation to low-income families. The Tribes' mission, under its Strategic Energy Plan of 2008, is to promote tribal efficiency, reduce energy costs, create jobs, economic opportunities, and incorporate energy planning in construction and economic development.

Control of collective properties of relativistic particles is increasingly important in modern accelerators. In particular, shot noise affects accelerator performance by driving instabilities or by competing with coherent processes. We present experimental observations of shot noise suppression in a relativistic beam at the Linac Coherent Light Source. By adjusting the dispersive strength of a chicane, we observe a decrease in the optical transition radiation emitted from a downstream foil. We show agreement between the experimental results, theoretical models, and 3D particle simulations.
