2010 Manufacturing Readiness Assessment Update to the 2008 Report for Fuel Cell Stacks and Systems for the Backup Power and Materials Handling Equipment Markets
In 2008, the National Renewable Energy Laboratory (NREL), under contract to the US Department of Energy (DOE), conducted a manufacturing readiness assessment (MRA) of fuel cell systems and fuel cell stacks for back-up power and material handling applications (MHE). To facilitate the MRA, manufacturing readiness levels (MRL) were defined that were based on the Technology Readiness Levels previously established by the US Department of Energy (DOE). NREL assessed the extensive existing hierarchy of MRLs developed by Department of Defense (DoD) and other Federal entities, and developed a MRL scale adapted to the needs of the Fuel Cell Technologies Program (FCTP) and to the status of the fuel cell industry. The MRL ranking of a fuel cell manufacturing facility increases as the manufacturing capability transitions from laboratory prototype development through Low Rate Initial Production to Full Rate Production. DOE can use MRLs to address the economic and institutional risks associated with a ramp-up in polymer electrolyte membrane (PEM) fuel cell production. In 2010, NREL updated this assessment, including additional manufacturers, an assessment of market developments since the original report, and a comparison of MRLs between 2008 and 2010.

The 2012 Gordon Research Conference on Mitochondria and Chloroplasts will assemble an international group of scientists investigating fundamental properties of these organelles, and their integration into broader physiological processes. The conference will emphasize the many commonalities between mitochondria and chloroplasts: their evolution from bacterial endosymbionts, their genomes and gene expression systems, their energy transducing membranes whose proteins derive from both nuclear and organellar genes, the challenge of maintaining organelle integrity in the presence of the reactive oxygen species that are generated during energy transduction, their incorporation into organismal signaling pathways, and more. The conference will bring together investigators working in animal, plant, fungal and protozoan systems who specialize in cell biology, genetics, biochemistry, physiology, proteomics, genomics, and structural biology. As such, this conference will provide a unique forum that engenders cross-disciplinary discussions concerning the biogenesis, dynamics, and regulation of these key cellular structures. By fostering interactions among mammalian, fungal and plant organellar biologists, this conference also provides a conduit for the transmission of mechanistic insights obtained in model organisms to applications in medicine and agriculture.

2012 MUTAGENESIS GORDON RESEARCH CONFERENCE, AUGUST 19-23, 2012
The delicate balance among cellular pathways that control mutagenic changes in DNA will be the focus of the 2012 Mutagenesis Gordon Research Conference. Mutagenesis is essential for evolution, while genetic stability maintains cellular functions in all organisms from microbes to metazoans. Different systems handle DNA lesions at various times of the cell cycle and in different places within the nucleus, and inappropriate actions can lead to mutations. While mutation in humans is closely linked to disease, notably cancers, mutational systems can also be beneficial. The conference will highlight topics of beneficial mutagenesis, including full establishment of the immune system, cell survival mechanisms, and evolution and adaptation in microbial systems. Equal prominence will be given to detrimental mutation processes, especially those involved in driving cancer, neurological diseases, premature aging, and other threats to human health. Provisional session titles include Branching Pathways in Mutagenesis; Oxidative Stress and Endogenous DNA Damage; DNA Maintenance Pathways; Recombination, Good and Bad; Problematic DNA Structures; Localized Mutagenesis; Hypermutation in the Microbial World; and Mutation and Disease.

2012 SRNL-EM VANE RHEOLOGY RESULTS
The vane method has been shown to be an effective tool in measuring the yield stress of both settled and mixed slurries in laboratory bench scale conditions in supporting assessments of both actual and simulant waste slurries. The vane has also been used to characterize dry powders and granular solids, the effect of non-cohesive solids with interstitial fluids and used as a guide to determine if slip is present in the geometries typically used to perform rheological flow curve measurements. The vane has been extensively characterized for measuring the shear strength in soils in both field and laboratory studies. The objectives for this task are: Fabricate vane instrument; Bench top testing to further characterize the effect of cohesive, non-cohesive, and blends of cohesive/non-cohesive simple simulants; Data from measurement of homogenized and settled bed of Kaolin sludge and assessment of the technology. In this document, the assessment using bench scale measurements of non-cohesive materials (beads) and cohesive materials (kaolin) is discussed. The non-cohesive materials include various size beads and the vane was assessed for depth and deaeration (or packing) via tapping measurements. For the cohesive (or non-Newtonian) materials, flow curves and yield stress measurements are performed using the vane and this …

2d Affine XY-Spin Model/4d Gauge Theory Duality and Deconfinement
We introduce a duality between two-dimensional XY-spin models with symmetry-breaking perturbations and certain four-dimensional SU(2) and SU(2) = Z{sub 2} gauge theories, compactified on a small spatial circle R{sup 1,2} x S{sup 1}, and considered at temperatures near the deconfinement transition. In a Euclidean set up, the theory is defined on R{sup 2} x T{sup 2}. Similarly, thermal gauge theories of higher rank are dual to new families of 'affine' XY-spin models with perturbations. For rank two, these are related to models used to describe the melting of a 2d crystal with a triangular lattice. The connection is made through a multi-component electric-magnetic Coulomb gas representation for both systems. Perturbations in the spin system map to topological defects in the gauge theory, such as monopole-instantons or magnetic bions, and the vortices in the spin system map to the electrically charged W-bosons in field theory (or vice versa, depending on the duality frame). The duality permits one to use the two-dimensional technology of spin systems to study the thermal deconfinement and discrete chiral transitions in four-dimensional SU(N{sub c}) gauge theories with n{sub f} {ge} 1 adjoint Weyl fermions.

3D COMSOL Simulations for Thermal Deflection of HFIR Fuel Plate in the "Cheverton-Kelley" Experiments
Three dimensional simulation capabilities are currently being developed at Oak Ridge National Laboratory using COMSOL Multiphysics, a finite element modeling software, to investigate thermal expansion of High Flux Isotope Reactor (HFIR) s low enriched uranium fuel plates. To validate simulations, 3D models have also been developed for the experimental setup used by Cheverton and Kelley in 1968 to investigate the buckling and thermal deflections of HFIR s highly enriched uranium fuel plates. Results for several simulations are presented in this report, and comparisons with the experimental data are provided when data are available. A close agreement between the simulation results and experimental findings demonstrates that the COMSOL simulations are able to capture the thermal expansion physics accurately and that COMSOL could be deployed as a predictive tool for more advanced computations at realistic HFIR conditions to study temperature-induced fuel plate deflection behavior.

L.A. Courthouse: Initial Project Justification Is Outdated and Flawed
Testimony issued by the Government Accountability Office with an abstract that begins "Because of delays and cost increases, the General Services Administration (GSA) canceled the authorized 41-courtroom Los Angeles (L.A.), California, courthouse project in 2006. Since then, GSA and the judiciary have been slow to agree upon how to proceed with the project, for which about $366 million in appropriated funds remains available. In 2012, with the judiciarys support, GSA issued a request for proposal for contractors to design and build a 24-courtoom, 32-chamber courthouse, which would be used in conjunction with 25 existing courtrooms in the Roybal Courthouse. However, this new plan will not address one of the principal justifications for the original projectthat the L.A. Court be centralized at one site. Instead, it would increase the distance between the Roybal Courthouse and the planned second court location and the distance to the federal detention center from which prisoners must be transported."

Accelerated deployment of nanostructured hydrotreating catalysts. Final CRADA Report.
Nanomanufacturing offers an opportunity to create domestic jobs and facilitate economic growth. In response to this need, U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy issued a Research Call to develop nanomanufacturing capabilities at the National Laboratories. High performance catalysts represent a unique opportunity to deploy nanomanufacturing technologies. Re-refining of used lube oil offers an opportunity to create manufacturing jobs and decrease dependence on imported petroleum. Improved catalysts are required to produce a better quality product, decrease environmental impact, extend catalyst life, and improve overall economics of lube oil re-refining. Argonne National Laboratory (Argonne) in cooperation with Universal Lubricants, Inc. (ULI) and Chemical Engineering Partners (CEP) have carried out a Cooperative Research and Development Agreement (CRADA) to prepare nanostructured hydrotreating catalysts using atomic layer deposition (ALD) to exhibit superior performance for the re-refining of used lube oil. We investigated the upgrading of recycled lube oil by hydrogenation using commercial, synthetically-modified commercial catalysts, and synthesized catalysts. A down-flow (trickle bed) catalytic unit was used for the hydrogenation experiments. In addition to carrying out elemental analyses of the various feed and product fractions, characterization was undertaken using H{sup 1} and C{sup 13} NMR. Initially commercial were evaluated. Second these …

Acculturation and Depression in Older Mexican American Adults: the Role of Social Support
Despite socioeconomic disadvantages, less acculturated Mexican Americans tend to exhibit better mental health than their more acculturated counterparts. However, in the case of older Mexican American adults, research has demonstrated the opposite to be true (Gonzalez, Haan, & Hinton, 2001). A variable of interest potentially responsible for this difference is social support. Thus, the current study proposed to investigate the mediation and moderation effects that social support has on the relationship between acculturation and depression in older Mexican American adults age 60 or older. Data from the Health and Retirement Study (HRS) was analyzed. Results showed that the mediating effect of contact with one’s children (-.109*) and the moderating effect of total social support and contact with one’s children (-.127*; -.103*) were statistically significant in the relationship between acculturation and depression. Although these effects are small they may still hold important implications for better understanding this population.

Advanced Gearless Drivetrain - Phase I Technical Report
Boulder Wind Power (ÃÂâÃÂÃÂÃÂÃÂBWPÃÂâÃÂÃÂÃÂÃÂ) collaborated with the National Renewable Energy Laboratory (NREL) in Golden, Colorado, to demonstrate the economics of scaling an advanced gearless drivetrain technology to 6MW (and larger) turbine applications. The project goal was to show that this advanced drivetrain technology enables a cost of energy of less than $0.10/kWH in offshore applications. This drivetrain technology achieves this Cost of Energy (ÃÂâÃÂÃÂÃÂÃÂCOEÃÂâÃÂÃÂÃÂÃÂ) advantage via a 70% greater torque density versus current state-of-the-art drivetrain technologies. In addition, a new dynamically compliant design strategy is required to optimize turbine system-level COE. The BWP generator is uniquely suited for this new design strategy. This project developed a concept design for a 6MW drivetrain and culminated in a plan for a system-level test of this technology at 3MW scale. The project further demonstrated the advantage of the BWP drivetrain with increasing power ratings, with conceptual designs through 10 MW.
