An Amplitude Analysis of the Decay B+- -> pi+- pi+- pi-+
The authors present a Dalitz-plot analysis of charmless B{sup {+-}} decays to the final state {pi}{sup {+-}}{pi}{sup {+-}}{pi}{sup {-+}} using 210 fb{sup -1} of data recorded by the BABAR experiment at {radical}s = 10.58 GeV. We measure the branching fractions {Beta}(B{sup {+-}} {yields} {pi}{sup {+-}}{pi}{sup {+-}}{pi}{sup {-+}}) = (16.2 {+-} 1.2 {+-} 0.9) x 10{sup -6} and {Beta}(B{sup {+-}} {yields} {rho}{sup 0}(770){pi}{sup {+-}}) = (8.8 {+-} 1.0 {+-} 0.6{sub -0.7}{sup +0.1}) x 10{sup -6}. Measurements of branching fractions for the quasi-two-body decays B{sup {+-}} {yields} {rho}{sup 0}(1450){pi}{sup {+-}}, B{sup {+-}} {yields} f{sub 0}(980){pi}{sup {+-}} and B{sup {+-}} f{sub 2}(1270){pi}{sup {+-}} are also presented. They observe no charge asymmetries for the above modes, and there is no evidence for the decays B{sup {+-}} {yields} {chi}{sub c0}{pi}{sup {+-}}, B{sup {+-}} {yields} f{sub 0}(1370){pi}{sup {+-}} and B{sup {+-}} {yields} {sigma}{pi}{sup {+-}}.

Analysis of Density Changes in Plutonium Observed from Accelerated Aging Using Pu-238 Enrichment
We present dimensional and density changes in an aging plutonium alloy enriched with 7.3 at.% of {sup 238}Pu and reference alloys of various ages. After 45 equivalent years of aging, the enriched alloys at 35 C have swelled in volume by 0.14 to 0.16% and now exhibit a near linear volume increase, without void swelling. Based on X-ray diffraction measurements, the lattice expansion by self-irradiation appears to be the primary cause for dimensional changes during the initial 2-3 years of aging. Following the initial transient, the density change is primarily cause by a constant helium in-growth rate as a result of {alpha}-particle decay.

Analysis of Meteorological Data Obtained During Flight in a Supercooled Stratiform Cloud of High Liquid-Water Content
"Flight icing-rate data obtained in a dense and abnormally deep supercooled stratiform cloud system indicated the existence of liquid-water contents generally exceeding values in amount and extent previously reported over the midwestern sections of the United States. Additional information obtained during descent through a part of the cloud system indicated liquid-water contents that significantly exceeded theoretical values, especially near the middle of the cloud layer. The growth of cloud droplets to sizes that resulted in sedimentation from the upper portions of the cloud is considered to be a possible cause of the high water contents near the center of the cloud layer" (p. 1).

APPLICATION FO FLOW FORMING FOR USE IN RADIOACTIVE MATERIAL PACKAGING DESIGNS
This paper reports on the development and testing performed to demonstrate the use of flow forming as an alternate method of manufacturing containment vessels for use in radioactive material shipping packaging designs. Additionally, ASME Boiler and Pressure Vessel Code, Section III, Subsection NB compliance along with the benefits compared to typical welding of containment vessels will be discussed. SRNL has completed fabrication development and the testing on flow formed containment vessels to demonstrate the use of flow forming as an alternate method of manufacturing a welded 6-inch diameter containment vessel currently used in the 9975 and 9977 radioactive material shipping packaging. Material testing and nondestructive evaluation of the flow formed parts demonstrate compliance to the minimum material requirements specified in applicable parts of ASME Boiler and Pressure Vessel Code, Section II. Destructive burst testing shows comparable results to that of a welded design. The benefits of flow forming as compared to typical welding of containment vessels are significant: dimensional control is improved due to no weld distortion; less final machining; weld fit-up issues associated with pipes and pipe caps are eliminated; post-weld non-destructive testing (i.e., radiography and die penetrant tests) is not necessary; and less fabrication steps are required.

An Application of the Coda Methodology for Moment-Rate Spectra Using Broadband Stations in Turkey
A recently developed coda magnitude methodology was applied to selected broadband stations in Turkey for the purpose of testing the coda method in a large, laterally complex region. As found in other, albeit smaller regions, coda envelope amplitude measurements are significantly less variable than distance-corrected direct wave measurements (i.e., L{sub g} and surface waves) by roughly a factor 3-to-4. Despite strong lateral crustal heterogeneity in Turkey, they found that the region could be adequately modeled assuming a simple 1-D, radially symmetric path correction. After calibrating the stations ISP, ISKB and MALT for local and regional distances, single-station moment-magnitude estimates (M{sub W}) derived from the coda spectra were in excellent agreement with those determined from multistation waveform modeling inversions, exhibiting a data standard deviation of 0.17. Though the calibration was validated using large events, the results of the calibration will extend M{sub W} estimates to significantly smaller events which could not otherwise be waveform modeled. The successful application of the method is remarkable considering the significant lateral complexity in Turkey and the simple assumptions used in the coda method.

Argonne Wakefield Accelerator facility upgrade.
The Argonne Wakefield Accelerator has been successfully used for conducting wakefield experiments in dielectric loaded structures and plasmas. Although the initial wakefield experiments were successful, higher drive beam quality would substantially improve the wakefield accelerating gradients. For this reason they have built a new 1-1/2 cell L-band photocathode RF gun. This gun is expected to produce 10-100 nC bunches with 2-5 ps rms pulse length and normalized emittance less than 100 mm mrad. The gun will initially have a copper photocathode, which will soon be replaced by a high quantum efficiency cesium telluride one, allowing the generation of a train of high charge bunches. the beam energy at the exit of the gun cavity will be in the range 7.5-10 MeV. A standing-wave linac structure operating at the same frequency (1.3 GHz) will increase the beam energy to about 15 MeV. This beam will be used in high-gradient wakefield acceleration experiments and other high intensity electron beam applications. Traveling-wave dielectric loaded structures, operating at 7.8 and 15.6 GHz, will be excited by the propagation of single bunches or by trains of up to 32 electron bunches, reaching gradients in excess of 100 MV/m over distances of the order of 1 …

Auditing and Its Regulators: Proposals for Reform After Enron
Auditors are regulated by both governmental agencies and professional organizations, though many now question whether this oversight is adequate. Enron’s auditor, Arthur Andersen, has been investigated by the U.S. Securities and Exchange Commission (SEC), several congressional committees, and other agencies, and it is facing numerous law suits. A federal jury convicted the firm on obstruction of justice charges on June 15, 2002. Other corporations and their auditors are also under scrutiny. Numerous accounting and audit reforms have been proposed, including some by the accounting industry. The House passed an audit reform bill (H.R. 3763) on April 24, 2002. The Senate passed an amended version of its bill (S. 2673) on July 15th. The SEC published proposed reform rules June 26th; on the 28th it required top executives in companies with revenues exceeding $1.2 billion to personally certify that filed reports are complete and accurate

Augustine Band of Cahuilla Indians Energy Conservation and Options Analysis - Final Report
The Augustine Band of Cahuilla Indians was awarded a grant through the Department of Energy First Steps program in June of 2006. The primary purpose of the grant was to enable the Tribe to develop energy conservation policies and a strategy for alternative energy resource development. All of the work contemplated by the grant agreement has been completed and the Tribe has begun implementing the resource development strategy through the construction of a 1.0 MW grid-connected photovoltaic system designed to offset a portion of the energy demand generated by current and projected land uses on the Tribe’s Reservation. Implementation of proposed energy conservation policies will proceed more deliberately as the Tribe acquires economic development experience sufficient to evaluate more systematically the interrelationships between conservation and its economic development goals.

Aviation Rulemaking: Incomplete Implementation Impaired FAA's Reform Efforts
Testimony issued by the General Accounting Office with an abstract that begins "This testimony discusses the results of GAO's review of the Federal Aviation Administration's (FAA) rulemaking process and ways to improve its efficiency. GAO found that the time FAA took to formally initiate a rule in response to a congressional mandate or a National Transportation Safety Board recommendation varied widely. Between fiscal year 1995 and fiscal year 2000, FAA initiated most such rules within two years, but some rules were initiated many years later. During the entire six-year period GAO reviewed FAA's median time for the final rule phase--about 15 months--was comparable to that of four other federal regulatory agencies. Over a shorter, more recent period, FAA took longer to complete this phase. In 1998, FAA developed reforms to address problems the pace of rulemaking, including the timing of management's involvement, the administration of the process, and human capital management issues. However, the reforms have yet to shorten the rulemaking process because they have not been fully or effectively implemented. Shifting priorities, some brought about by external events and some by internal circumstances, have continued to delay the pace of rulemaking. In addition, difficult policy issues have sometimes remained …

Aviation Security: TSA Has Enhanced Its Explosives Detection Requirements for Checked Baggage, but Additional Screening Actions Are Needed
A letter report issued by the Government Accountability Office with an abstract that begins "Explosives represent a continuing threat to aviation security. The Transportation Security Administration (TSA), within the Department of Homeland Security (DHS), seeks to ensure through the Electronic Baggage Screening Program (EBSP) that checked-baggage-screening technology is capable of detecting explosives. Generally, the explosives detection system (EDS) is used in conjunction with explosives trace detection (ETD) machines to identify and resolve threats in checked baggage. As requested, GAO assessed the extent to which: (1) TSA revised explosives detection requirements and deployed technology to meet those requirements, and (2) TSA's approach to the current EDS acquisition meets best practices for schedules and cost estimates and includes plans for potential upgrades of deployed EDSs. GAO analyzed EDS requirements, compared the EDS acquisition schedule against GAO best practices, and interviewed DHS officials. This is a public version of a sensitive report that GAO issued in May 2011."
