Conventional resonant bar tests allow the measurement of seismic properties of rocks and sediments at low frequencies (several kilohertz). However, the tests require a long, slender sample which is often difficult to obtain from the deep subsurface and weak and fractured formations. We present an alternative low-frequency measurement technique to the conventional resonant bar tests. This technique involves a jacketed core sample placed between a pair of long, metal extension rods with attached seismic source and receiver—the same geometry as the split Hopkinson pressure bar test for large-strain, dynamic impact experiments. Because of the added length and mass to the sample, the resonance frequency of the entire system can be lowered significantly, compared to the sample alone. The proposed “Split Hopkinson Resonant Bar (SHRB)” test is applied in two steps. In the first step, extension and torsion-mode resonance frequencies and attenuation of the system are measured. Then, numerical inversions for the compressional and shear wave velocities and attenuation are performed. We initially applied the SHRB test to synthetic materials (plastics) for testing its accuracy, then used it for measuring the seismic velocities and attenuation of a rock core containing supercritical CO{sub 2}, and a sediment core while methane hydrate formed …

HyPerComp Inc. in research collaboration with TEXCEL has set out to build a Virtual Test Blanket Module (VTBM) computational system to address the need in contemporary fusion research for simulating the integrated behavior of the blanket, divertor and plasma facing components in a fusion environment. Physical phenomena to be considered in a VTBM will include fluid flow, heat transfer, mass transfer, neutronics, structural mechanics and electromagnetics. We seek to integrate well established (third-party) simulation software in various disciplines mentioned above. The integrated modeling process will enable user groups to interoperate using a common modeling platform at various stages of the analysis. Since CAD is at the core of the simulation (as opposed to computational meshes which are different for each problem,) VTBM will have a well developed CAD interface, governing CAD model editing, cleanup, parameter extraction, model deformation (based on simulation,) CAD-based data interpolation. In Phase-I, we built the CAD-hub of the proposed VTBM and demonstrated its use in modeling a liquid breeder blanket module with coupled MHD and structural mechanics using HIMAG and ANSYS. A complete graphical user interface of the VTBM was created, which will form the foundation of any future development. Conservative data interpolation via CAD (as …

This report begins with a brief examination of clean energy, renewable energy, and alternative energy. It then presents possible selection criteria Congress could use to determine which sources could be eligible for a CES depending on the goal(s) of the CES. The report provides an overview of the energy sources most commonly discussed as potential CES qualifying sources: biomass, fossil fuels (natural gas combined-cycle and coal-fired power plants with carbon capture and sequestration), geothermal resources, nuclear, solar, water, and wind. The report describes where each source can be found in the United States, the estimated quantity available for electricity generation, technologies used to create electricity from the source, advantages and disadvantages of using the source for electricity generation, and policy implications should the source be included in a CES.5 The report also contains a section on energy efficiency and its potential inclusion in a CES.

The construction sector is a major component of the U.S. economy. During the past decade, construction was a prime beneficiary of low interest rates and the housing-led economic boom, but was also one of the largest casualties of the subsequent financial crisis. Construction spending comprised about 7%-8% of U.S. annual economic output from 1995 to mid-2000, reaching nearly 9% of gross domestic product at the peak of the housing run-up in 2006, before declining to about 5% in 2010. Likewise, construction employment ranged from a low of about 4.6 million during the early 1990s to a high of 7.7 million during the 2006 housing boom, and was about 5.5 million in early 2011.

Côte d'Ivoire is emerging from a severe political-military crisis that followed a disputed November 28, 2010, presidential runoff election between former president Laurent Gbagbo and his, former Prime Minister Alassane Ouattara. Both claimed electoral victory and formed opposing governments. Their rivalry spurred a full-scale civil military conflict in early March 2011, after months of growing political violence. Armed conflict largely ended days after Gbagbo's arrest by pro-Ouattara forces, aided by United Nations (U.N.) and French peacekeepers, but limited residual fighting was continuing to occur as of April 20.

This report discusses about Côte d’Ivoire which is emerging from a severe political-military crisis that followed a disputed November 28, 2010, Presidential runoff election between former president Laurent Gbagbo and his, former Prime Minister Alassane Ouattara.

Key definitions are also included.

Ferrimagnetic Mn{sub 3-x}Co{sub x}Ga compounds have been investigated by magnetic circular dichroism in x-ray absorption (XMCD). Compounds with x > 0.5 crystallize in the CuHg{sub 2}Ti structure. A tetragonal distortion of the cubic structure occurs for x {le} 0.5. For the cubic phase, magnetometry reveals a linearly increasing magnetization of 2x Bohr magnetons per formula unit obeying the generalized Slater-Pauling rule. XMCD confirms the ferrimagnetic character with Mn atoms occupying two different sublattices with antiparallel spin orientation and different degrees of spin localization and identifies the region 0.6 < x {le} 0.8 as most promising for a high spin polarization at the Fermi level. Individual Mn moments on inequivalent sites are compared to theoretical predictions.

The local structure and 4f orbital occupancy have been investigated in Ce{sub 1−x}Yb{sub x}CoIn{sub 5} via Yb L{sub III}-edge extended x-ray absorption fine structure (EXAFS), Ce and Yb L{sub III}-edge x-ray absorption near-edge structure (XANES), and angle-resolved photoemission spectroscopy (ARPES) measurements. Yb(III) (4f{sup 13}) is the hole analog of Ce(III) (4f{sup 1}). Yb is found to be strongly intermediate-valent in Ce{sub 1−x}Yb{sub x}CoIn{sub 5} throughout the entire doping range, including pure YbCoIn{sub 5}, with an f-hole occupancy for Yb of n{sub f} ≃ 0.3 (i.e. Yb{sup 2.3+}), independent of Yb concentration and independent of temperature down to T = 20 K. In contrast, the f-electron orbital occupancy for Ce remains close to 1 for all Yb concentrations, suggesting that there is no mutual influence on n{sub f} between neighboring Ce and Yb sites. Likewise, ARPES measurements at 12 K have found that the electronic structure along {Gamma} − X is not sensitive to the Yb substitution, suggesting that the Kondo hybridization of Ce f electrons with the conduction band is not affected by the presence of Yb impurities in the lattice. The emerging picture is that in Ce{sub 1−x}Yb{sub x}CoIn{sub 5} there are two networks, interlaced but independent, that couple …

This report discusses a variety of issues related to expedited recission measures that may prove of possible interest to congress. It also discusses Expedited Rescission Proposals in the 111th, 112th Congress.

Expedited rescission bills focus on procedural changes in Congress and typically contain a detailed schedule to ensure immediate introduction of a measure to approve the President's rescission request, prompt reporting by committee or automatic discharge, special limits on floor amendments and debate, and so on. Under expedited rescission, congressional approval is still necessary to rescind the funding, but the fast-track procedures may help to encourage an up-or down vote on the President's proposal.

This document compares the performance of various hydrodynamic models on a common benchmark problem, The Corpus Christi Bay benchmark, designed by Texas Water Development Board (TWDB). The benchmark problem includes a data-set for calibration of the model and another data-set for verification of the model. The application of the Finite-Volume Coastal Ocean Model (FVCOM) to this benchmark problem enabled TWDB to evaluate the strengths and weaknesses of the model for use in predicting the three-dimensional circulation and salinity transport in bay and estuary systems on the Texas coast. (p. 2).
