Child Welfare: Improved Federal Oversight Could Assist States in Overcoming Key Challenges
Testimony issued by the General Accounting Office with an abstract that begins "Title IV-B of the Social Security Act, comprised of two subparts, is the primary source of federal funding for services to help families address problems that lead to child abuse and neglect and to prevent the unnecessary separation of children from their families; however, a number of challenges exist that impair states' ability to deliver and track these services. This testimony is based on findings from three reports issued in 2003 and addresses the following: (1) states' use of Title IV-B funds in providing a wide array of services to prevent the occurrence of abuse, neglect, and unnecessary foster care placements, as well as in providing other child welfare services; (2) factors that hinder states' ability to protect children from abuse and neglect; and (3) the Department of Health and Human Services' (HHS) role in helping states to overcome these challenges. Findings are based on multiple methodologies, including a survey to child welfare directors on states' use of Title IV-B funds; an analysis of nearly 600 exit interview documents completed by staff who severed their employment from 17 state, 40 county, and 19 private child welfare agencies; and …

Collisional Transport in a Low Aspect Ratio Tokamak -- Beyond the Drift Kinetic Formalism
Calculations of collisional thermal and particle diffusivities in toroidal magnetic plasma confinement devices order the toroidal gyroradius to be small relative to the poloidal gyroradius. This ordering is central to what is usually referred to as neoclassical transport theory. This ordering is incorrect at low aspect ratio, where it can often be the case that the toroidal gyroradius is larger than the poloidal gyroradius. We calculate the correction to the particle and thermal diffusivities at low aspect ratio by comparing the diffusivities as determined by a full orbit code (which we refer to as omni-classical diffusion) with those from a gyroaveraged orbit code (neoclassical diffusion). In typical low aspect ratio devices the omni-classical diffusion can be up to 2.5 times the calculated neoclassical value. We discuss the implications of this work on the analysis of collisional transport in low aspect ratio magnetic confinement experiments.

Comparisons of U.S. and Foreign Military Spending: Data from Selected Public Sources
This report lists and compares military expenditures of the United States and foreign nations using two sources: the London-based International Institute for Strategic Studies’ (IISS) The Military Balance, and the U.S. State Department’s World Military Expenditures and Arms Transfers (WMEAT). Although the IISS and the U.S. State Department aim to provide figures that are as consistent and accurate as possible, cross-national comparisons of defense spending are inherently imperfect. Available sets of figures are useful, but often do not correspond with one another for a variety of reasons. This report provides two sets of figures from widely recognized sources in order to offer Congress a sample of the data published on this topic.

A COMPUTATIONAL WORKBENCH ENVIRONMENT FOR VIRTUAL POWER PLANT SIMULATION
This is the thirteenth Quarterly Technical Report for DOE Cooperative Agreement No: DE-FC26-00NT41047. The goal of the project is to develop and demonstrate a Virtual Engineering-based framework for simulating the performance of Advanced Power Systems. Within the last quarter, good progress has been made on all aspects of the project. Software development efforts have focused on a preliminary detailed software design for the enhanced framework. Given the complexity of the individual software tools from each team (i.e., Reaction Engineering International, Carnegie Mellon University, Iowa State University), a robust, extensible design is required for the success of the project. In addition to achieving a preliminary software design, significant progress has been made on several development tasks for the program. These include: (1) the enhancement of the controller user interface to support detachment from the Computational Engine and support for multiple computer platforms, (2) modification of the Iowa State University interface-to-kernel communication mechanisms to meet the requirements of the new software design, (3) decoupling of the Carnegie Mellon University computational models from their parent IECM (Integrated Environmental Control Model) user interface for integration with the new framework and (4) development of a new CORBA-based model interfacing specification. A benchmarking exercise to compare …

A Cumulant-based Analysis of Nonlinear Magnetospheric Dynamics
Understanding magnetospheric dynamics and predicting future behavior of the magnetosphere is of great practical interest because it could potentially help to avert catastrophic loss of power and communications. In order to build good predictive models it is necessary to understand the most critical nonlinear dependencies among observed plasma and electromagnetic field variables in the coupled solar wind/magnetosphere system. In this work, we apply a cumulant-based information dynamical measure to characterize the nonlinear dynamics underlying the time evolution of the Dst and Kp geomagnetic indices, given solar wind magnetic field and plasma input. We examine the underlying dynamics of the system, the temporal statistical dependencies, the degree of nonlinearity, and the rate of information loss. We find a significant solar cycle dependence in the underlying dynamics of the system with greater nonlinearity for solar minimum. The cumulant-based approach also has the advantage that it is reliable even in the case of small data sets and therefore it is possible to avoid the assumption of stationarity, which allows for a measure of predictability even when the underlying system dynamics may change character. Evaluations of several leading Kp prediction models indicate that their performances are sub-optimal during active times. We discuss possible improvements …

Direct Conversion of Carbon Fuels in a Molten Carbonate Fuel Cell
Anodes of elemental carbon may be discharged in a galvanic cell using a molten carbonate electrolyte, a nickel-foam anode-current collector, and a porous nickel air cathode to achieve power densities of 40-100 mW/cm{sup 2}. We report cell and anode polarization, surface area, primary particle size and a crystallization index for nine particulate carbon samples derived from fuel oil, methane, coal, charred biological material and petroleum coke. At 800 C, current densities of 50-125 mA/cm{sup 2} were measured at a representative cell voltage of 0.8 V. Power densities for cells with two carbon-anode materials were found to be nearly the same on scales of 2.8- and 60 cm{sup 2} active area. Constant current operation of a small cell was accompanied by constant voltage during multiple tests of 10-30 hour duration. Cell voltage fell off after the carbon inventory was consumed. Three different cathode structures are compared, indicating that an LLNL fabricated porous nickel electrode with <10 {micro}m pores provides improved rates compared with nickel foam with 100-300 {micro}m pores. Petroleum coke containing substantial sulfur and ash discharges at a slightly lower rate than purified petroleum coke. The sulfur leads to degradation of the anode current collector over time. A conceptual model …

A Dynamically Adaptive Arbitrary Lagrangian-Eulerian Method for Hydrodynamics
A new method that combines staggered grid Arbitrary Lagrangian-Eulerian (ALE) techniques with structured local adaptive mesh refinement (AMR) has been developed for solution of the Euler equations. The novel components of the combined ALE-AMR method hinge upon the integration of traditional AMR techniques with both staggered grid Lagrangian operators as well as elliptic relaxation operators on moving, deforming mesh hierarchies. Numerical examples demonstrate the utility of the method in performing detailed three-dimensional shock-driven instability calculations.

Final Project Report for Grant DE-FG03-00ER54581 Selective Control of Chemical Reactions With Plasmas
OAK-B135 This research work focused on control of the reactive species inside a plasma through measurement and manipulation of the electron energy distribution function (EEDF) and on understanding the surface reaction mechanisms on the substrate exposed to a combination of ion and atom beam sources to simulate a real plasma. A GEC chamber (Gaseous Electronic Conference Reference Cell)8 with a mass spectrometer and a Langmuir probe (LP) system were used for this research. It was found that H2 and N2 additives to an Ar plasma could effectively change the EEDF and the average electron temperature (Te). This finding provides the possibility to selectively control reaction rates in the plasma to control etching selectivity on a surface. This concept was demonstrated in Ar/N2/H2 and Ar/CH4 /H2 systems.

Flor-Essence? Herbal Tonic Promotes Mammary Tumor Development in Sprague Dawley Rats
Background: Women who are diagnosed with breast cancer often self-administer complementary and alternative medicines to augment their conventional treatments, improve health, or prevent recurrence. Flor-Essence{reg_sign} Tonic is a complex mixture of herbal extracts used by cancer patients because of anecdotal evidence that it can treat or prevent disease. Methods: Female Sprague Dawley rats were given water or exposed to 3% or 6% Flor-Essence{reg_sign} beginning at one day of age. Mammary tumors were induced with a single oral 40 mg/kg/bw dose of dimethylbenz(a)anthracene at 50 days of age and sacrificed at 23 weeks. Rats were maintained on AIN-76A diet. Results: Control rats had palpable mammary tumor incidence of 51.0% at 19 weeks of age compared to 65.0% and 59.4% for the 3% and 6% Flor-Essence{reg_sign} groups respectively. Overall, no significant difference in time until first palpable tumor was detected among any of the groups. At necropsy, mammary tumor incidence was 82.5% for controls compared to 90.0% and 97.3% for rats consuming 3% and 6% Flor-Essence{reg_sign}, respectively. Mean mammary tumor multiplicity ({+-}SES) for the controls was 2.8 ({+-} 0.5) and statistically different from the 3% or 6% Flor- Essence{reg_sign} groups with 5.2 ({+-} 0.7), and 4.8 ({+-} 0.6), respectively (p{<=}0.01). As expected, …
