Observation of e^+e^- to \rho^+\rho^- near \sqrt{s}=10.58\gev
The authors report the first observation of e{sup +}e{sup -} {yields} {rho}{sup +}{rho}{sup -}, in a data sample of 379 fb{sup -1} collected with the BABAR detector at the PEP-II e{sup +}e{sup -} storage ring at center-of-mass energies near {radical}s = 10.58 GeV. The authors measure a cross section of {sigma}(e{sup +}e{sup -} {yields} {rho}{sup +}{rho}{sup -}) = 19.5 {+-} 1.6(stat) {+-} 3.2(syst) fb. Assuming production through single-photon annihilation, there are three independent helicity amplitudes. They measure the ratios of their squared moduli to be |F{sub 00}|{sup 2} : |F{sub 10}|{sup 2} : |F{sub 11}|{sup 2} = 0.51 {+-} 0.14(stat) {+-} 0.07(syst) : 0.10 {+-} 0.04(stat) {+-} 0.01(syst) : 0.04 {+-} 0.03(stat) {+-} 0.01(syst). The |F{sub 00}|{sup 2} result is inconsistent with the prediction of 1.0 made by QCD models with a significance of 3.1 standard deviations including systematic uncertainties.

Overcoming Constraints to High-Yield Plantation-Grown Hardwoods in the Southeastern United States
This project was comprised of the following four inter-related tasks: Task 1 Plantation Maintenance and Measurement--Data on dry weight productivity per tree and/or growth as measured by individual tree height and diameter at a specified height on the stem was determined at the end of each of five years corresponding to ages 2 through 6. Measurements of height and diameter were recorded once a month during the growing season on a subsample of four trees per clone per species per treatment combination. Dry biomass in the leaf litter traps during the growing season once the canopy has closed was periodically collected and measured. Foliar nutrient levels were determined once a month by removing LPI 8 on each subsampled measurement tree and completing nutrient analyses. Weather data, including precipitation, minimum and maximum temperature and photosynthetically active radiation on an hourly basis were recorded daily. Information on irrigation rates and fertilization levels were collected. Task 2 Intra- And Interspecific Variation In Osmotic Potential--The specific objectives of this task were: (1) to determine whether limitation in water availability constrains productivity and influences leaf osmotic potential of cottonwood, sycamore, and/or sweetgum growing under short-rotation field conditions, (2) to document the occurrence of osmotic adjustment …

Peacekeeping: Thousands Trained but United States Is Unlikely to Complete All Activities by 2010 and Some Improvements Are Needed
A letter report issued by the Government Accountability Office with an abstract that begins "In 2004, in response to the Group of Eight (G8) Sea Island Summit, the United States established the Global Peace Operations Initiative (GPOI), a 5-year program to build peacekeeping capabilities worldwide, with a focus on Africa. Since 2005, the Department of State (State) has allocated $374 million and selected 52 countries to participate in the program. Congress mandated that GAO assess and report on the initiative. This report assesses (1) progress made in meeting GPOI goals, (2) whether State is consistently assessing the quality and effectiveness of the training, and (3) the extent to which countries meet program criteria and whether trainees are adequately screened for human rights abuses. GAO assessed State and Department of Defense (DOD) data and program documents, interviewed U.S. and host country officials, and conducted field work in eight countries."

Second Quarter Hanford Seismic Report for Fiscal Year 2008
The Hanford Seismic Assessment Program (HSAP) provides an uninterrupted collection of high-quality raw and processed seismic data from the Hanford Seismic Network for the U.S. Department of Energy and its contractors. The Hanford Seismic Assessment Team locates and identifies sources of seismic activity and monitors changes in the historical pattern of seismic activity at the Hanford Site. The data are compiled, archived, and published for use by the Hanford Site for waste management, natural phenomena hazards assessments, and engineering design and construction. In addition, the seismic monitoring organization works with the Hanford Site Emergency Services Organization to provide assistance in the event of a significant earthquake on the Hanford Site. The Hanford Seismic Network and the Eastern Washington Regional Network consist of 44 individual sensor sites and 15 radio relay sites maintained by the Hanford Seismic Assessment Team. For the Hanford Seismic Network, seven local earthquakes were recorded during the second quarter of fiscal year 2008. The largest event recorded by the network during the second quarter (February 3, 2008 - magnitude 2.3 Mc) was located northeast of Richland in Franklin County at a depth of 22.5 km. With regard to the depth distribution, two earthquakes occurred at shallow depths …

Secure Border Initiative Fiscal Year 2008 Expenditure Plan Shows Improvement, but Deficiencies Limit Congressional Oversight and DHS Accountability
Correspondence issued by the Government Accountability Office with an abstract that begins "In November 2005, the Department of Homeland Security (DHS) announced the launch of Secure Border Initiative (SBI), a multiyear, multibillion-dollar program aimed at securing U.S. borders and reducing illegal immigration. Elements of SBI are carried out by several organizations within DHS. One component is the U.S. Customs and Border Protection's (CBP) SBI program office, which is responsible for developing a comprehensive border protection system using people; technology, known as SBInet; and tactical infrastructure (TI)--pedestrian and vehicle fencing; roads; and lighting. Initially, the focus of SBI is on the U.S. southwest border areas, between the ports of entry, that CBP has designated as most in need of enhanced border security because of serious vulnerabilities. In September 2006, CBP awarded a prime contract to the Boeing Company for 3 years, with three additional 1-year options. As the prime contractor, Boeing is responsible for acquiring, deploying, and sustaining selected SBInet technology and tactical infrastructure projects, and for providing supply chain management for selected tactical infrastructure projects. For fiscal years 2005 through 2008, Congress appropriated more than $2.7 billion for the SBI program. For fiscal year 2009, the President's budget includes a …

Simulation of Wakefield Effect in ILC IR Chamber
To achieve super high luminosity, high current beams with very short bunch length are needed, which carry high intensity EM fields. For ILC, two bunch trains with bunch length of 300 {micro}m and bunch charge of 3.2nC are needed to collide at the IR to achieve the ILC luminosity goals. When the 300 {micro}m bunches pass through the IR chamber, wakefields will be excited, which will cause HOM power flowing through the IR chamber beam pipe to the final doublets due to the high frequency characteristic of the induced wakefields. Since superconducting technology is adopted for the final doublets of ILC BDS, whose operation stability might be affected by the HOM power produced at the IR chamber, quench might happen. In this paper, we did some analytical estimation and numerical simulation on the wakefield effects in ILC IR chamber.

Tax Expenditures: Available Data Are Insufficient to Determine the Use and Impact of Indian Reservation Depreciation
A letter report issued by the Government Accountability Office with an abstract that begins "Indians lag behind other Americans on many key economic indicators, such as median household income. To improve such conditions, Congress in 1993 created Indian reservation depreciation (IRD), a tax expenditure offering accelerated depreciation for property invested on Indian reservations. GAO was asked to (1) describe which taxpayers claimed IRD, (2) analyze the effect of IRD on the economic development of reservations, and (3) describe the tax benefits offered by IRD. GAO used the Internal Revenue Service's (IRS) Statistics of Income data to try to identify IRD users and measure IRD's effects; however, the data were unreliable for those purposes. GAO also calculated examples of potential IRD tax benefits for different property classes."

TESTING OF A ROTARY MICROFILTER TO SUPPORT HANFORD APPLICATIONS
Savannah River National Laboratory (SRNL) researchers are investigating and developing a rotary microfilter for solid-liquid separation applications at the Savannah River Site (SRS). Because of the success of that work, the Hanford Site is evaluating the use of the rotary microfilter for its Supplemental Pretreatment process. The authors performed rotary filter testing with a full-scale, 25-disk unit with 0.5 {micro} filter media manufactured by Pall Corporation using a Hanford AN-105 simulant at solids loadings of 0.06, 0.29, and 1.29 wt%. The conclusions from this testing are: (1) The filter flux at 0.06 wt% solids reached a near constant value at an average of 0.26 gpm/ft{sup 2} (6.25 gpm total). (2) The filter flux at 0.29 wt% solids reached a near constant value at an average of 0.17 gpm/ft{sup 2} (4 gpm total). (3) The filter flux at 1.29 wt% solids reached a near constant value at an average of 0.10 gpm/ft{sup 2} (2.4 gpm total). (4) Because of differences in solids loadings, a direct comparison between crossflow filter flux and rotary filter flux is not possible. The data show the rotary filter produces a higher flux than the crossflow filter, but the improvement is not as large as seen in …

Thermal Performance Analysis for Wsb Drum
The Nuclear Nonproliferation Programs Design Authority is in the design stage of the Waste Solidification Building (WSB) for the treatment and solidification of the radioactive liquid waste streams generated by the Pit Disassembly and Conversion Facility (PDCF) and Mixed Oxide (MOX) Fuel Fabrication Facility (MFFF). The waste streams will be mixed with a cementitious dry mix in a 55-gallon waste container. Savannah River National Laboratory (SRNL) has been performing the testing and evaluations to support technical decisions for the WSB. Engineering Modeling & Simulation Group was requested to evaluate the thermal performance of the 55-gallon drum containing hydration heat source associated with the current baseline cement waste form. A transient axi-symmetric heat transfer model for the drum partially filled with waste form cement has been developed and heat transfer calculations performed for the baseline design configurations. For this case, 65 percent of the drum volume was assumed to be filled with the waste form, which has transient hydration heat source, as one of the baseline conditions. A series of modeling calculations has been performed using a computational heat transfer approach. The baseline modeling results show that the time to reach the maximum temperature of the 65 percent filled drum is …
