The sustained propagation of combustion fronts in porous media is a necessary condition for the success of an in situ combustion project for oil recovery. Compared to other recovery methods, in situ combustion involves the added complexity of exothermic reactions and temperature-dependent chemical kinetics. In the presence of heat losses, the possibility of ignition and extinction (quenching) exists. In this report, we address the properties of combustion fronts propagating at a constant velocity in the presence of heat losses.

This report provides historical background of the Council, including the role of the previous Commission. It discusses the Council's current mandate and structure, as well as U.S. policy and congressional actions.

Renewable power technologies are inherently capital-intensive, often (but not always) with relatively high construction costs and low operating costs. For this reason, renewable power technologies are typically more sensitive to the availability and cost of financing than are natural gas power plants, for example. In the United States, the bulk of renewable project finance in recent years has been provided by 'tax equity investors' (typically large investment banks and insurance companies) who partner with project developers through highly specialized financing structures (Bolinger, 2009; Cory et al., 2008; Harper et al., 2007). These structures have been designed primarily to capitalize on federal support for renewable power technologies, which has historically come in the form of tax credits and accelerated depreciation deductions. The number of tax equity investors active in the renewable power market has declined precipitously, however, as a result of the financial crisis that began unfolding across the globe in the summer of 2008. The resulting shortage and increased cost of project financing has, in turn, slowed the development of new renewable power projects, leading to layoffs throughout the entire industry supply chain. In recognition of the fact that tax-based policy incentives are not particularly effective when tax burdens are …

This report discusses issues surrounding Japan's interest in purchasing the F-22A Raptor aircraft from the United States. Although the export of the plane is now prohibited by U.S. law, Congress has recently and may again consider repealing this ban.

Described is a manual,portable non-destructive technique to determine the through wall height of cracks present in dissimilar metal welds used in the primary coolling systems of pressure water and boiler light water reactors. Current manual methods found in industry have proven not to exhibit the sizing accuracy required by ASME inspection requirement. The technique described demonstrated an accuracy approximately three times that required to ASME Section XI, Appendix 8 qualification.

Staff of Brookhaven National Laboratory, Columbia University, IBM and the RIKEN BNL Research Center organized a one-day workshop held on February 28, 2003 at Brookhaven to promote the following goals: (1) To explore areas other than QCD applications where the QCDOC and BlueGene/L machines can be applied to good advantage, (2) To identify areas where collaboration among the sponsoring institutions can be fruitful, and (3) To expose scientists to the emerging software architecture. This workshop grew out of an informal visit last fall by BNL staff to the IBM Thomas J. Watson Research Center that resulted in a continuing dialog among participants on issues common to these two related supercomputers. The workshop was divided into three sessions, addressing the hardware and software status of each system, prospective applications, and future directions.

Dissolution experiments were conducted on radioactive sludge from Tank 7, before transfer of the contents of Tank 7 to Tank 51, and the subsequent sludge in Tank 51 to evaluate the effectiveness of the DWPF Cold Chem Method. The DWPF Cold Chem Method is a room temperature dissolution method (DWPF Cold Chem Method) used in the DWPF on the Slurry Receipt and Adjustment Tank (SRAT) samples in preparation for instrumental analysis. Four types of dissolutions experiments were carried out, the DWPF Cold Chem Method, hot aqua regia, sodium peroxide fusion and hot HF-HNO3. The hot HF-HNO3 digestion is modified version of the DWPF method that incorporates a heating step. The hot aqua regia and sodium peroxide fusion digestions were included as reference digestions. The resulting solutions from all the sludge digestions were analyzed by ICP-ES (Inductively Coupled Plasma Emission Spectroscopy). Visual observations and ICP-ES results were used to evaluate the effectiveness of the DWPF Cold Chem by comparison to the hot aqua regia, sodium peroxide fusion and the hot HF-HNO3 digestions. The data and experimental observations support the following conclusions: The DWPF Cold Chem Method seemed to be effective at dissolving initial species of radioactive sludge, but concurrent precipitation of …

This report discusses the ongoing debate about whether or not to approve energy development in the Arctic National Wildlife Refuge (ANWR). Current law forbids energy leasing in the Refuge. This report addresses several legislative options on the issue, as well as policymakers' arguments for and against development, especially in the wake of increasing terrorism since 2000-2001.

In the 107th Congress, renewed efforts are underway to enact a permanent replacement for the Export Administration Act of 1979 (EAA), temporarily reauthorized in the 106th Congress until August 20, 2001. The Export Administration Act of 2001 (S. 149) was introduced on January 23, 2001. Hearings were held by the Senate Banking Committee, and the bill was reported for consideration by the full Senate by a vote of 19-1 to March 22, 2001. The difficulty in passing a comprehensive rewrite of the EAA has resulted, in part, from the continuing tension between national security and commercial concerns. Industry groups, proponents of heightened export controls, the Administration, and Congress have all participated in the reauthorization debate.

The Export Administration Act of 2001 was introduced on January 23, 2001. Hearings were held by the Senate Banking, Housing, and Urban Affairs Committee, and the bill was reported for consideration by the full Senate by a vote of 19-1 to March 22, 2001. A companion version in the House, H.R. 2581, was introduced by Rep. Gilmanon July 20, 2001. The House International Relations Committee reported the measure with 35 amendments on August 1. The Export Administration Act of 1979 expired on August 20, 2001, however the President extended export control authority and the Export Administration Regulations by invoking the International Emergency Economic Powers Act. During the 106th Congress, both houses held hearings on export control legislation and the Senate Banking Committee voted to adopt the Export Administration Act of 1999 (S. 1712, reported on October 8, 1999, S.Rept. 106-180).
