[en] Enhancing situational awareness by mining social media has been widely studied, but little work has been done focusing on recovery phases. To provide evidence to support the possibility of harnessing social media as a sensor of recovery activities, we examine the correlations between topic frequencies on Twitter and people’s socioeconomic recovery activities as reflected in the excess demand for used cars and housing, after the Great East Japan Earthquake and Tsunami of 2011. Our research suggests that people in the disaster-stricken area communicated more about recovery and disaster damages when they needed to purchase used cars, while the nonlocal population communicated more about going to and supporting the disaster-stricken area. On the other hand, regarding the excess demand for housing, when the local population of the disaster-stricken area started to resettle, they communicated their opinions more than in other periods about disaster-related situations.

[en] Detailed design parameters of a new, high-resolution electron monochromator are presented. The design utilizes a hemispherical filter as the energy-dispersing element and combines both cylindrical and aperture electrostatic lenses to accelerate, decelerate, transport, and focus the electron beam from the cathode to the interaction region

[en] We have performed high-field/high-frequency ESR measurements on the interacting S=((1)/(2)) dimer system KCuCl₃. The magnetic excitation of this material is studied in a wide frequency region up to 2 THz (8.3 meV) and in a pulsed high magnetic field up to 55 T

[en] This study is part of the Basalt Waste Isolation Project, operated for the US Department of Energy by Rockwell Hanford Operations. The overall purpose of the study is to assess locations within the Columbia River Basalt Group beneath the Hanford Site in south-central Washington suitable for a geologic repository for radioactive waste. This hydrologic study was made to describe the hydrologic characteristics of the basalt units of the Columbia Plateau. This was done by comprehensive data compilation, data interpretation and analysis. Data are presented in the form of maps and tables suitable as input information about the regional hydrology for possible future analysis by computer models. The report includes: an introduction; basic data; interpretation which covers stratigraphic trend surface, water levels, transmissivity and storage of aquifers, recharge, discharge, flow, subbasins, cross sections, references and appendix of record of wells

[en] The standard free energies for formation of AlF₃, ThF₄, UF₃, UF₄, CrF₂, MnF₂ and CrF₃ were determined by emf measurements. From the emf values and Δ/sup f/ G⁰ (MgF₂) obtained from Δ/sup f/ H⁰ data by calorimetry measurements, the standard free energies of formation of the above fluorides at 600⁰C were calculated as follows: Δ/sup f/ G⁰ (AlF₃) = -306.0 +- 0.2, Δ/sup f/ G⁰ (ThF₄) = -436.6 +- 0.8, Δ/sup f/ G⁰ (UF₃) = -310.9 +- 0.8: Δ/sup f/ G⁰ (UF₄) = -394.0 +- 1.3, Δ/sup f/ G⁰ (CrF₂) = -156.4 +- 0.3, Δ/sup f/ G⁰ (MnF₂) = -175.0 +- 0.2, Δ/sup f/ G⁰ (CrF₃) = -229.1 +- 1.0 (kcal/mol).

[en] The Pauli blocking effect on the pionic decay rate of sub(Λ)⁵He is investigated with the Λ-α potential obtained from the hard-core Λ-N potential. The repulsive core of the Λ-N interaction reduces the Pauli blocking effect and enhances the pionic decay rate by about 30%. The lifetime of sub(Λ)⁵He evaluated is in good agreement with the experimental one. (author)

[en] Several wet and dry methods for the conversion of UF₆ to UO₂ powder, e.g., the ammonium diuranate (ADU) process and the integrated dry route process, have been developed to an industrial scale. Although the UO₂ powders fabricated by conventional methods have good ceramic characteristics, there is room for improvement. To extend burnup of nuclear fuel, a decrease in fission gas release from UO₂ pellets is required. It has been considered that large-grain pellets satisfy this requirement, but it is difficult to obtain such large-grain pellets by using conventional UO₂ powder. A new method has been developed to produce a highly active UO₂ powder that can greatly contribute to improvement of the fabrication process of nuclear fuel pellet. By using this highly active UO₂ powder, large-grain pellets can be made easily, and low-temperature sintering can be achieved

[en] The objective of this compilation is to present a comprehensive listing of the published, unpublished, and open file references pertaining to the surface and subsurface hydrology of the Columbia River basalts within the State of Washington and is presented in support of Rockwell's hydrologic data compilation effort for the Basalt Waste Isolation Program. A comprehensive, annotated bibliography of the Pasco Basin (including the Hanford Site) hydrology has been prepared for Rockwell as part of the Pasco Basin hydrology studies. In order to avoid unnecessary duplication, no effort was made to include a complete list of bibliographic references on Hanford in this volume

[en] Deformation slip and twinning in Ti--Al--V alloys were studied using acoustic emission. It was found that acoustic emission during plastic deformation of titanium and Ti--6Al--4V alloy were accompanied by twin formation. Furthermore, it is important that acoustic emission technique is an effective method for detecting twinning. (auth)

[en] This study proposed a new approach to apply the steric pore-flow model to predict the rejection of eight N-nitrosamines and seven VOCs that are of great concern in potable water reuse through an RO membrane. In this approach, solute rejection is predicted by estimating the free-volume hole-size. The free-volume hole-radius was determined with pure water permeability of a membrane and a single reference compound N-nitrosodimethylamine (NDMA) by minimizing the variance between the experimentally obtained and calculated NDMA rejection values at the permeate flux of 20 L/m2 h. The obtained free-volume hole-radius of ESPA2 RO membrane was 0.348 nm, which was larger than the value previously determined by positron annihilation lifetime spectroscopy (PALS) analysis (0.289 nm). The model incorporated with the estimated free-volume hole-radius could accurately predict the rejection of eight N-nitrosamines under a range of permeate flux (2.6–20 L/m2 h). The model was also validated using experimentally obtained VOC rejection values. The predicted VOC rejections at the permeate flux of 20 L/m2 h were almost identical to their experimentally obtained rejections. However, VOC rejection prediction at a lower permeate flux was less accurate. Further improvement and validation of the model with a variety of trace organic chemicals is required to allow for a more accurate prediction. The model was also validated using the membrane free-volume hole-radius value previously obtained from PALS analysis. Using PALS data resulted in some over-prediction. The results suggest that PALS analysis cannot allow for model prediction unless additional adjustment is provided to improve the prediction accuracy
