Analysis of bacterial spore permeability to water and ions using Nano-Secondary Ion Mass Spectrometry (NanoSIMS)
Regulation of bacterial spore solvent and solute permeability is a fundamental feature of dormancy but is poorly understood. Here we present a new technique, nano-scale secondary ion mass spectrometry (NanoSIMS) that allows the direct visualization and quantification of chemical gradients within spores. Using NanoSIMS, we demonstrate the penetration of water and a simple ionic salt, LiF, into the core of Bacillus thuringiensis israelensis (Bti) spores. The results demonstrate chemical gradients spanning the outer coat to the inner spore core that are driven by concentration-dependent ionic fluxes. Using deuterated water (D{sub 2}O), we have shown that external water is either retained or exchanged with water contained within the spore. Hydration and exchange are rapid, on a timescale of < 1 minute. Our results suggest a permeation mechanism by which short-time scale diffusion into and out of the spore can occur along hydration pathways. Additional studies are in progress to define the flux rates and mechanisms controlling these processes.

Aviation Safety: FAA's Safety Oversight System Is Effective but Could Benefit from Better Evaluation of Its Programs' Performance
A statement of record issued by the Government Accountability Office with an abstract that begins "The U.S. commercial aviation industry has an extraordinary safety record. However, when passenger airlines have accidents or serious incidents, regardless of their rarity, the consequences can be tragic. The Federal Aviation Administration (FAA) works to maintain a high level of safety through an effective safety oversight system. Keys to this system are to: (1) establish programs that focus resources on areas of highest safety risk and on mitigating risks; (2) provide training and communication to ensure that inspectors can consistently carry out the agency's oversight programs; and (3) have processes and data to continuously monitor, evaluate, and improve the numerous oversight programs that make up the safety oversight system. This statement focuses on these three key areas and is based on recent GAO reports on FAA's inspection oversight programs, industry partnership programs, enforcement program, and training program."

THE BC CRIBS & TRENCHES GEOPHYSICAL CHARACTERIZATION PROJECT ONE STEP FORWARD IN HANFORDS CLEANUP PROCESS
A geophysical characterization project was conducted at the BC Cribs and Trenches Area, located south of 200 East at the Hanford Site. The area consists of 26 waste disposal trenches and cribs, which received approximately 30 million gallons of liquid waste from the uranium recovery process and the ferrocyanide processes associated with wastes generated by reprocessing nuclear fuel. Waste discharges to BC Cribs contributed perhaps the largest liquid fraction of contaminants to the ground in the 200 Areas. The site also includes possibly the largest inventory of Tc-99 ever disposed to the soil at Hanford with an estimated quantity of 400 Ci. Other waste constituents included high volumes of nitrate and U-238. The geophysical characterization at the 50-acre site primarily included high resolution resistivity (HRR). The resistivity technique is a non-invasive method by which electrical resistivity data are collected along linear transects, and data are presented as continuous profiles of subsurface electrical properties. The transects ranged in size from about 400-700 meters and provided information down to depths of 60 meters. The site was characterized by a network of 51 HRR lines with a total of approximately 19.7 line kilometers of data collected parallel and perpendicular to the trenches and …

D.C. Charter Schools: Strengthening Monitoring and Process When Schools Close Could Improve Accountability and Ease Student Transitions
A letter report issued by the Government Accountability Office with an abstract that begins "D.C. has a larger percentage of students in charter schools than any state. To help oversee D.C. charter schools, Congress established two authorizers--the Board of Education (BOE), which has an Office of Charter Schools responsible for oversight, and the independent Public Charter School Board (PCSB). Congress required the GAO to conduct a study of the authorizers. This report--which completes GAO's May 2005 study--examines the (1) authorizers' resources, (2) oversight practices, and (3) actions taken once charter schools close. GAO examined BOE and PCSB monitoring reports, revenue and expenditure documents, and closure procedures."

CALE EOS form 2 fits for high pressure fused silica Hugoniot data
The Hugoniot data on fused silica that are displayed on page 321 of the well-known volume ''LASL Shock Hugoniot Data, Stanley P. Marsh, Editor'' are fit to the EOS form 2 such as is used in CALE and other hydrocodes. Two fits are given: one to represent that data set over its full range (up to 84 GPa (840 kbar)) as well as a better fit for the pressure range below about 33 GPa (330 kbar). These EOSs have the strong point of being relatively simple for the user to implement and should be used to roughly represent the beyond-elastic response of fused silica in hydrocode simulations. They will not correctly reproduce the complex multiple-wave ramp-shock structure known to exist in fused silica at lower pressures.

Calibration of Parameters in Beta-Delta HMX Phase Transformation Kinetics Using Computer Simulations
The kinetics of the beta-delta solid-solid phase transformation of HMX (nitramine octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine) were modeled in ALE2D using four similar equilibrium-inhibited nucleation-growth models: a reversible set of Arrhenius kinetics following a LANL model, and three sets of kinetics derived based on an autocatalytic model using the bidirectional reaction formalism. The parameters for the bidirectional kinetics models were calibrated using simulations of two experimental setup scenarios where experimental data is available: 165 C XRD and SITI. In this calibration, the transition enthalpy and activation energy values were kept constant, while the frequency factors were iterated to achieve results similar to those provided by the experiments. This process yielded six unique sets of kinetic parameters that describe the phase transformation: a pair of sets for each of the three bidirectional kinetics models. The models calibrated using 165 C XRD data showed good agreement with LX-04 STEX experimental results, while the SITI-based models were in good agreement with the LANL model and PBX-9501 STEX experimental data. These bidirectional models were also shown to require less computational effort than the LANL model.

CFO Act of 1990: Driving the Transformation of Federal Financial Management
Testimony issued by the Government Accountability Office with an abstract that begins "In 1990, the Chief Financial Officers (CFO) Act, heralded as the most comprehensive financial management reform legislation in 40 years, was enacted. The Act's goal is to improve management through reliable, useful, and timely financial and performance information for day-to-day decisionmaking and accountability. This testimony outlines the legislative history of the CFO Act, and its key elements, progress to date in implementing the Act, and the challenges for the future. Prior to passage of the CFO Act, the seemingly never ending disclosures of fraud, waste, abuse, and mismanagement in federal programs painted a picture of a government unable to manage its programs, protect its assets, or provide taxpayers with the effective and economical services they expect. The enactment of the CFO Act represented a broad-based recognition that federal financial management was in great need of fundamental reform. The Act mandated a financial management leadership structure; required the preparation and audit of annual financial statements; called for modernized financial management systems and strengthened internal control; and required the systematic measurement of performance, the development of cost information, and the integration of program, budget, and financial systems."

Chemical Analysis Of Beryllium Shells
There is a need to understand the level of high-Z impurities in Beryllium shells prepared by sputter coating. The Ignition Point Design Requirements state the following: ''Except for allowed ingredients, as listed in the ablator composition entries, the ablator material in all layers shall contain sufficiently low impurity levels that the sum over all impurities of atom fraction*Z{sup 2} shall be less than or equal to 0.2''. This is a tight specification that requires careful materials analysis. Early in the first quarter of FY06, we undertook a study of Be shell impurities via ICP-MS{sup 2} and determined that the impurity levels in the sputtered shells are very close to the specification.

Complete Photo-Induced Breakup of the H2 Molecule as a Probe ofMolecular Electron Correlation
Despite decades of progress in quantum mechanics, electron correlation effects are still only partially understood. Experiments in which both electrons are ejected from an oriented hydrogen molecule by absorption of a single photon have recently demonstrated a puzzling phenomenon: The ejection pattern of the electrons depends sensitively on the bond distance between the two nuclei as they vibrate in their ground state. Here we report a complete numerical solution of the Schrodinger equation for the double photoionization of H2. The results suggest that the distribution of photoelectrons emitted from aligned molecules reflects electron correlation effects that are purely molecular in origin.
