The 222-S Laboratory contains 155 active fume hoods that are used to support analytical work with radioactive and/or toxic materials. The performance of a fume hood was brought into question after employees detected odors in the work area while mixing chemicals within the subject fume hood. Following the event, testing of the fume hood was conducted to assess the performance of the fume hood. Based on observations from the testing, it was deemed appropriate to conduct performance evaluations of other fume hoods within the laboratory.

Compositional data are represented as vector variables with individual vector components ranging between zero and a positive maximum value representing a constant sum constraint, usually unity (or 100 percent). The earth sciences are flooded with spatial distributions of compositional data, such as concentrations of major ion constituents in natural waters (e.g. mole, mass, or volume fractions), mineral percentages, ore grades, or proportions of mutually exclusive categories (e.g. a water-oil-rock system). While geostatistical techniques have become popular in earth science applications since the 1970s, very little attention has been paid to the unique mathematical properties of geostatistical formulations involving compositional variables. The book 'Geostatistical Analysis of Compositional Data' by Vera Pawlowsky-Glahn and Ricardo Olea (Oxford University Press, 2004), unlike any previous book on geostatistics, directly confronts the mathematical difficulties inherent to applying geostatistics to compositional variables. The book righteously justifies itself with prodigious referencing to previous work addressing nonsensical ranges of estimated values and error, spurious correlation, and singular cross-covariance matrices.

The Department of Homeland Security has proposed security regulations for chemical facilities, implementing the statutory authority granted in Homeland Security Appropriations Act, 2007. The proposed regulations require chemical facilities possessing amounts and yes of substances considered by the DHS Secretary to be hazardous to notify DHS and undergo a consequence-based screening process. This report details the proposed regulations issued by the Department of Homeland Security, key issues, and policy options related to chemical facility security.

We investigate the climate forcing from and response to projected changes in short-lived species and methane under the A1B scenario from 2000-2050 in the GISS climate model. We present a meta-analysis of new simulations of the full evolution of gas and aerosol species and other existing experiments with variations of the same model. The comparison highlights the importance of several physical processes in determining radiative forcing, especially the effect of climate change on stratosphere-troposphere exchange, heterogeneous sulfate-nitrate-dust chemistry, and changes in methane oxidation and natural emissions. However, the impact of these fairly uncertain physical effects is substantially less than the difference between alternative emission scenarios for all short-lived species. The net global mean annual average direct radiative forcing from the short-lived species is .02 W/m{sup 2} or less in our projections, as substantial positive ozone forcing is largely offset by negative aerosol direct forcing. Since aerosol reductions also lead to a reduced indirect effect, the global mean surface temperature warms by {approx}0.07 C by 2030 and {approx}0.13 C by 2050, adding 19% and 17%, respectively, to the warming induced by long-lived greenhouse gases. Regional direct forcings are large, up to 3.8 W/m{sup 2}. The ensemble-mean climate response shows little regional …

In the context of eternal inflation we discuss the fate of Lambda = 0 bubbles when they collide with Lambda< 0 crunching bubbles. When the Lambda = 0 bubble is supersymmetric, it is not completely destroyed by collisions. If the domain wall separating the bubbles has higher tension than the BPS bound, it is expelled from the Lambda = 0 bubble and does not alter its long time behavior. If the domain wall saturates the BPS bound, then it stays inside the Lambda = 0 bubble and removes a finite fraction of future infinity. In this case, the crunch singularity is hidden behind the horizon of a stable hyperbolic black hole.

We perform a maximum likelihood analysis of the cluster abundance measured in the SDSS using the maxBCG cluster finding algorithm. Our analysis is aimed at constraining the power spectrum normalization {sigma}{sub 8}, and assumes flat cosmologies with a scale invariant spectrum, massless neutrinos, and CMB and supernova priors {Omega}{sub m}h{sup 2} = 0.128 {+-} 0.01 and h = 0.72 {+-} 0.05 respectively. Following the method described in the companion paper Rozo et al. (2007), we derive {sigma}{sub 8} = 0.92 {+-} 0.10 (1{sigma}) after marginalizing over all major systematic uncertainties. We place strong lower limits on the normalization, {sigma}{sub 8} > 0.76 (95% CL) (> 0.68 at 99% CL). We also find that our analysis favors relatively low values for the slope of the Halo Occupation Distribution (HOD), {alpha} = 0.83 {+-} 0.06. The uncertainties of these determinations will substantially improve upon completion of an ongoing campaign to estimate dynamical, weak lensing, and X-ray cluster masses in the SDSS maxBCG cluster sample.

Some in Congress have expressed concern about the government's use of private-sector lead system integrators (LSIs) for executing large, complex defense-related acquisition programs. LSIs are large, prime contractors hired to manage such programs.The 110th Congress has also introduced legislation to require the federal government to study the use of LSIs, and legislation wich would prohibit the use of LSIs for remaining contracts under the Deepwater Program. This report contains information on the background on LSIs, potential oversight issues for Congress, potential options for Congress, and legislative activity as related to this issue.

Correspondence issued by the Government Accountability Office with an abstract that begins "This report responds to Congress's request that GAO determine the status and estimated costs of environmental cleanup on the island of Vieques. For decades, the U.S. Navy conducted ship-to-shore bombing exercises and other live-fire training activities on the island, which is located off the coast of Puerto Rico. The Navy ceased its operations on Vieques in 2003. The Navy has transferred the land to the Municipality of Vieques and the Puerto Rico Conservation Trust for conservation purposes and to the Department of the Interior. Although the land has been transferred, the Navy remains responsible for environmental cleanup. The cleanup is being carried out under the Defense Environmental Restoration Program (DERP) that consists of (1) the Installation Restoration Program, which addresses cleanup of hazardous substances, and (2) the Military Munitions Response Program, which addresses cleanup of munitions."

Correspondence issued by the Government Accountability Office with an abstract that begins "On January 17, 2007, GAO testified before Congress on the Department of Defense's (DOD) management of its acquisition of services. GAO made several key points during the hearing. First, DOD's long-standing problems with contract management have become more prominent as DOD's reliance on contractors to provide services continues to grow. Second, DOD lacks sound contracting practices when acquiring services. Third, DOD's acquisition workforce has been downsized without sufficient attention to requisite skills and competencies. Fourth, DOD's acquisitions have resulted in outcomes that have cost the department valuable resources. And, finally, while DOD is taking some steps to address these problems, it does not know how well its services acquisition processes are working, which part of its mission can best be met through buying services, and whether it is obtaining the services it needs while protecting DOD's and the taxpayer's interests. Within this context, members of Congress requested that GAO provide additional comments on DOD's efforts regarding the following topics: interagency contracting, acquisition of services, acquisition reform, and the acquisition workforce."
