100-D Area In Situ Redox Treatability Test for Chromate-Contaminated Groundwater: FY 1998 Year-End Report
A treatability test was conducted for the In Situ Redox Manipulation (ISRM) technology at the US Department of Energy's Hanford, Washington 100D Area. The target contaminant was dissolved chromate [Cr(VI)] in groundwater. The ISRM technology involves creating a permeable subsurface treatment zone to reduce mobile chromate in groundwater to an insoluble form. The ISRM permeable treatment zone is created by reducing ferric iron [Fe(III)] to ferrous iron [Fe(II)] within the aquifer sediments. This is accomplished by injecting aqueous sodium dithionite into the aquifer and withdrawing the reaction products. The goal of the treatability test was to create a linear ISRM barrier by injecting sodium dithionite into five wells. Well installation and site characterization activities began in the spring of 1997. The first dithionite injection took place in September 1997. The results of this first injection were monitored through the spring of 1998; the remaining four dithionite injections were carried out in May through July of 1998. These five injections created a reduced zone in the Hanford unconfined aquifer 150 feet in length (perpendicular to groundwater flow) by 50 feet wide. The reduced zone extended over the thickness of the unconfined zone, which is approximately 15 feet. Analysis of recent groundwater …

2010 Census: Bureau Needs to Specify How It Will Assess Coverage Follow-up Techniques and When It Will Produce Coverage Measurement Results
A letter report issued by the Government Accountability Office with an abstract that begins "An accurate decennial census relies on finding and counting people--only once--in the right place and collecting complete and correct information. GAO reviewed the Department of Commerce's U.S. Census Bureau's (Bureau) plans to (1) improve the census's accuracy--or coverage--with its coverage follow-up operation, (2) assess the accuracy of the census through its census coverage measurement program, and (3) evaluate these efforts after 2010. GAO reviewed documentation and interviewed Bureau officials about the Bureau's coverage follow-up and measurement plans. GAO compared plans for measuring coverage in 2000 and 2010 and interviewed 15 experts about changes to the plans."

2010 Census: Census at Critical Juncture for Implementing Risk Reduction Strategies
Testimony issued by the Government Accountability Office with an abstract that begins "In 2007, the U.S. Census Bureau (Bureau) estimated the 2010 Census would cost $11.5 billion, including $3 billion on automation and technology. At a March hearing, the Department of Commerce (Commerce) stated that the Field Data Collection Automation (FDCA) program was likely to incur significant cost overruns and announced a redesign effort. At that time, GAO designated the 2010 Decennial Census as high risk, citing long-standing concerns in managing information technology (IT) investments and uncertain costs and operations. This testimony is based on past work and work nearing completion, including GAO's observation of the address canvassing dress rehearsal. For IT acquisitions, GAO analyzed system documentation, including deliverables, cost estimates, other acquisitions-related documents, and interviewed Bureau officials and contractors. This testimony describes the implications of redesign for (1) dress rehearsal and decennial operations, (2) IT acquisitions management, and (3) Decennial Census costs."

Administrative Subpoenas and National Security Letters in Criminal and Foreign Intelligence Investigations: Background and Proposed Adjustments
Administrative subpoena authority, including closely related national security letter authority, is the power vested in various administrative agencies to compel testimony or the production of documents or both in aid of the agencies’ performance of their duties. During the 108th Congress, the President urged Congress to expand and re-enforce statutory authority to use administrative subpoenas and national security letters in criminal and foreign intelligence investigations; and legislation was introduced for that purpose. Related proposals have been offered during the 109th Congress, some of which deal with national security letter authority. Proponents of expanded use emphasize the effectiveness of administrative subpoenas as an investigative tool and question the logic of its availability in drug and health care fraud cases but not in terrorism cases. Critics suggest that it is little more than a constitutionally suspect “trophy” power, easily abused and of little legitimate use.

Administrative Subpoenas and National Security Letters in Criminal and Intelligence Investigations: A Sketch
Administrative subpoena authority, including closely related national security letter authority, is the power vested in various administrative agencies to compel testimony or the production of documents or both in aid of the agencies’ performance of their duties. Both the President and Members of Congress have called for statutory adjustments relating to the use of administrative subpoenas and national security letters in criminal and foreign intelligence investigations. One lower federal court has found the sweeping gag orders and lack of judicial review that mark one of the national security letter practices constitutionally defective. Proponents of expanded use emphasize the effectiveness of administrative subpoenas as an investigative tool and question the logic of its availability in drug and health care fraud cases but not in terrorism cases. Critics suggest that it is little more than a constitutionally suspect “trophy” power, easily abused and of little legitimate use. This is an abridged version — without footnotes, appendices, quotation marks and most citations to authority — of Administrative Subpoenas and National Security Letters in Criminal and Foreign Intelligence Investigations: Background and Proposed Adjustments, CRS Report RL32880.

Advanced Turbine Systems (ATS): Phase 1 system scoping and feasibility studies
As part of this involvement Solar intends to design and commercialize a unique gas turbine system that promises high cycle efficiencies and low exhaust emissions. This engine of approximately 12-MW will be targeted for the dispersed power markets both urban and rural. Goals of 50% thermal efficiency and 8 parts-per-million by volume (ppmv) nitrogen oxide emissions were established. Reliability, availability, and maintainability (RAM) will continue to be the most important factors in the competitive marketplace. The other major goal adopted was one of reducing the cost of power produced by 10%. This reduction is based on the cost of power (COP) associated with today`s engines that lie in the same horsepower range as that targeted in this study. An advanced cycle based on an approximation of the Ericsson Cycle was adopted after careful studies of a number of different cycles. This advanced intercooled, recuperated engine when fired at 2450{degree}F will be capable of meeting the 50% efficiency goal if the cooling air requirements do not exceed 7% of the total air flow rate. This latter qualification will probably dictate the use of ceramic parts for both the nozzle guide vanes and the turbine blades. Cooling of these parts will probably …

ADVANCED WAVEFORM SIMULATION FOR SEISMIC MONITORING EVENTS
The recent Nevada Earthquake (M=6) produced an extraordinary set of crustal guided waves. In this study, we examine the three-component data at all the USArray stations in terms of how well existing models perform in predicting the various phases, Rayleigh waves, Love waves, and Pnl waves. To establish the source parameters, we applied the Cut and Paste Code up to distance of 5° for an average local crustal model which produced a normal mechanism (strike=35°,dip=41°,rake=-85°) at a depth of 9 km and Mw=5.9. Assuming this mechanism, we generated synthetics at all distances for a number of 1D and 3D models. The Pnl observations fit the synthetics for the simple models well both in timing (VPn=7.9km/s) and waveform fits out to a distance of about 5°. Beyond this distance a great deal of complexity can be seen to the northwest apparently caused by shallow subducted slab material. These paths require considerable crustal thinning and higher P-velocities. Small delays and advances outline the various tectonic province to the south, Colorado Plateau, etc. with velocities compatible with that reported on by Song et al.(1996). Five-second Rayleigh waves (Airy Phase) can be observed throughout the whole array and show a great deal of variation …

Advances in Low-Defect Multilayers for EUVL Mask Blanks
Low-defect multilayer coatings are required to fabricate mask blanks for Extreme Ultraviolet Lithography (EUVL). The mask blanks consist of high reflectance E W multilayers on low thermal expansion substrates. A defect density of 0.0025 printable defects/cm{sup 2} for both the mask substrate and the multilayer is required to provide a mask blank yield of 60%. Current low defect multilayer coating technology allows repeated coating-added defect levels of 0.05/cm{sup 2} for defects greater than 90 nm polystyrene latex sphere (PSL) equivalent size for lots of 20 substrates. Extended clean operation of the coating system at levels below 0.08/cm{sup 2} for 3 months of operation has also been achieved. Two substrates with zero added defects in the quality area have been fabricated, providing an existence proof that ultra low defect coatings are possible. Increasing the ion source-to-target distance from 410 to 560 mm to reduce undesired coating of the ion source caused the defect density to increase to 0.2/cm{sup 2}. Deposition and etching diagnostic witness substrates and deposition pinhole cameras showed a much higher level of ion beam spillover (ions missing the sputter target) than expected. Future work will quantify beam spillover, and test designs to reduce spillover, if it is confirmed …
