EM-21 HIGHER WASTE LOADING GLASSES FOR ENHANCED DOE HIGH-LEVEL WASTE MELTER THROUGHPUT STUDIES - 10194
Supplemental validation data has been generated that will be used to determine the applicability of the current Defense Waste Processing Facility (DWPF) liquidus temperature (T{sub L}) model to expanded DWPF glass regions of interest based on higher waste loadings. For those study glasses which had very close compositional overlap with the model development and/or model validation ranges (except TiO{sub 2} and MgO concentrations), there was very little difference in the predicted and measured TL values, even though the TiO{sub 2} contents were above the 2 wt% upper limit. The results indicate that the current T{sub L} model is applicable in these compositional regions. As the compositional overlap between the model validation ranges diverged from the target glass compositions, the T{sub L} data suggest that the model under-predicted the measured values. These discrepancies imply that there are individual oxides or their combinations that were outside of the model development and/or validation range over which the model was previously assessed. These oxides include B{sub 2}O{sub 3}, SiO{sub 2}, MnO, TiO{sub 2} and/or their combinations. More data is required to fill in these anticipated DWPF compositional regions so that the model coefficients could be refit to account for these differences.

EXAMINATION OF SHIPPING PACKAGES 9975-01818, 9975-01903 AND 9975-02287
Three 9975 shipping packages were examined to investigate the non-conforming condition of an axial air gap greater than 1 inch. This condition typically indicates the presence of excess moisture in the fiberboard overpack, and may be accompanied by degradation in the fiberboard properties. The package with the largest axial air gap (9975-01818, with an air gap of 1.437 inches) was found to contain significant excess moisture, and the lower fiberboard assembly was covered with mold and was significantly degraded in strength. This condition is very similar to that observed previously in package 9975-01819. Both packages (-1818 and -1819) appear to contain a similar amount of excess moisture, which was previously estimated for 9975-01819 as {approx}2.5 liters. The condition of 9975-01818 was also evidenced by several rust spots along the bottom chime of the drum, although no significant rust was noted on the closure bolts. Packages 9975-01903 and 9975-02287 were also examined. The axial air gap in these two packages was less than in 9975-01818, but still exceeded 1 inch. These two packages contained elevated moisture levels, although not significantly higher than seen in other 'typical' packages. The fiberboard in these two packages was of sound integrity, and appeared generally consistent …

Extended model for Richtmyer-Meshkov mix
We examine four Richtmyer-Meshkov (RM) experiments on shock-generated turbulent mix and find them to be in good agreement with our earlier simple model in which the growth rate h of the mixing layer following a shock or reshock is constant and given by 2{alpha}A{Delta}v, independent of initial conditions h{sub 0}. Here A is the Atwood number ({rho}{sub B}-{rho}{sub A})/({rho}{sub B} + {rho}{sub A}), {rho}{sub A,B} are the densities of the two fluids, {Delta}V is the jump in velocity induced by the shock or reshock, and {alpha} is the constant measured in Rayleigh-Taylor (RT) experiments: {alpha}{sup bubble} {approx} 0.05-0.07, {alpha}{sup spike} {approx} (1.8-2.5){alpha}{sup bubble} for A {approx} 0.7-1.0. In the extended model the growth rate beings to day after a time t*, when h = h*, slowing down from h = h{sub 0} + 2{alpha}A{Delta}vt to h {approx} t{sup {theta}} behavior, with {theta}{sup bubble} {approx} 0.25 and {theta}{sup spike} {approx} 0.36 for A {approx} 0.7. They ascribe this change-over to loss of memory of the direction of the shock or reshock, signaling transition from highly directional to isotropic turbulence. In the simplest extension of the model h*/h{sub 0} is independent of {Delta}v and depends only on A. They find that h*/h{sub …

Final Report: Grant DE-FG02-05ER15682. Simulation of Complex Microphase Formation in Pure and Nanoparticle-filled Diblock Copolymers
The goal of this project was to use molecular simulation to quantify the impact of additives on the onset and structure of bicontinuous phases in linear diblock copolymers (DBC). The focus was on understanding how additives with selective affinity for a given block will distribute and perturb the structure of complex bicontinuous phases (like gyroid, double diamond, and plumbers nightmare whose minority component block forms two interweaving 3D networks) in DBCs; it was hypothesized that a suitable choice of additive type, size, affinity, and concentration may suppress or stabilize a particular bicontinuous phase. The ultimate goal in this line of investigation is to elucidate the rational design of the optimal additive for which the composition range of stability of a particular bicontinuous phase is maximized. Ours are the first published simulation studies to report on the formation of the gyroid phase in DBC melts and of other bicontinuous phases in DBC-modified by homopolymer. The following tasks were carried out: (i) simulation of bicontinuous phases of pure DBCs via both on-lattice Monte Carlo simulations and continuum-space Monte Carlo and molecular dynamics simulations, (ii) determination of the effect of selective additives (homopolymer) of different sizes on such bicontinuous phases, and (iii) development …

Homeland Security: Greater Attention to Key Practices Would Help Address Security Vulnerabilities at Federal Buildings
Testimony issued by the Government Accountability Office with an abstract that begins "The Federal Protective Service (FPS) within the Department of Homeland Security (DHS) is responsible for providing law enforcement and related security services for nearly 9,000 federal facilities under the control and custody of the General Services Administration (GSA). In 2004 GAO identified a set of key protection practices from the collective practices of federal agencies and the private sector, which included allocation of resources using risk management, strategic management of human capital, leveraging of technology, information sharing and coordination, and performance measurement and testing. This testimony is based on past reports and testimonies and discusses (1) limitations FPS faces in protecting GSA buildings and resulting vulnerabilities; and (2) actions FPS is taking. To perform this work, GAO used its key practices as criteria, visited a number of GSA buildings, surveyed tenant agencies, analyzed pertinent laws and DHS and GSA documents, conducted covert testing at 10 judgmentally selected high-security buildings in four cities, and interviewed officials from DHS, GSA, and tenant agencies, and contractors and guards."

Laser Wakefield Acceleration at Reduced Density in the Self-Guided Regime
Experiments conducted using a 200TW 60 fs laser have demonstrated up to 720 MeV electrons in the self-guided laser wakefield regime using pure Helium gas jet targets. Charge and energy of the accelerated electrons was measured using an electron spectrometer with a 0.5T magnet and charge callibrated image plates. The self-trapped charge in a helium plasma was shown to fall off with decreasing electron density with a threshold at 2.5 x 10{sup 18} (cm{sup -3}) below which no charge is trapped. Self-guiding however is shown to continue below this density limitation over distances of 14 mm with an exit spot size of 25{micro}m. Simulations show that injection of electrons at these densities can be assisted through ionization induced trapping in a mix of Helium with 3% Oxygen.

Scintillation Properties of Eu2+-Activated Barium Fluoroiodide
The scintillation properties of powders and single-crystals of BaFI doped with Eu2+ are presented. Single crystals were grown by the vertical Bridgman technique. Under optical and X-ray excitation, the samples exhibit a narrow E2+ 5d-4f transition emission centered at 405 nm. The scintillation light output is estimated to be 55,000+-5,000 photons/MeV at 662 keV with 85percent of the light decaying within 600 ns. An energyresolution of 8.5percent full width at half maximum (FWHM) has been achieved using this scintillator for 662 keV excitation (137Cs source) at room temperature.

Towards a Research Agenda for Cyber Friendly Fire
Historical assessments of combat fratricide reveal principal contributing factors in the effects of stress, degradation of skills due to continuous operations or sleep deprivation, poor situation awareness, and lack of training and discipline in offensive/defense response selection. While these problems are typically addressed in R&D focusing on traditional ground-based combat, there is also an emerging need for improving situation awareness and decision making on defensive/offensive response options in the cyber defense arena, where a mistaken response to an actual or perceived cyber attack could lead to destruction or compromise of friendly cyber assets. The purpose of this report is to examine cognitive factors that may affect cyber situation awareness and describe possible research needs to reduce the likelihood and effects of "friendly cyber fire" on cyber defenses, information infrastructures, and data. The approach is to examine concepts and methods that have been described in research applied to the more traditional problem of mitigating the occurrence of combat identification and fratricide. Application domains of interest include cyber security defense against external or internal (insider) threats.

Transportation Worker Identification Credential: Progress Made in Enrolling Workers and Activating Credentials but Evaluation Plan Needed to Help Inform the Implementation of Card Readers
A letter report issued by the Government Accountability Office with an abstract that begins "The Transportation Worker Identification Credential (TWIC) program, which is managed by the Department of Homeland Security's (DHS) Transportation Security Administration (TSA) and the U.S. Coast Guard, requires maritime workers who access secure areas of transportation facilities to obtain a biometric identification card to access these facilities. A federal regulation set a national compliance deadline of April 15, 2009. TSA is conducting a pilot program to test the use of TWICs with biometric card readers in part to inform the development of a second TWIC regulation. The Government Accountability Office (GAO) was asked to evaluate TSA's and the Coast Guard's progress and related challenges in implementing TWIC, and to evaluate the management challenges, if any, TSA, Coast Guard, and DHS face in executing the TWIC pilot test. GAO reviewed TWIC enrollment and implementation documents and conducted site visits or interviewed officials at the seven pilot program sites."
