Apparatus for real-time acoustic imaging of Rayleigh-Bénard convection (open access)

Apparatus for real-time acoustic imaging of Rayleigh-Bénard convection

We have successfully designed, built and tested an experimental apparatus which is capable of providing the first real-time ultrasound images of Rayleigh-B\'{e}nard convection in optically opaque fluids confined to large aspect ratio experimental cells. The apparatus employs a modified version of a commercially available ultrasound camera to capture images (30 frames per second) of flow patterns in a fluid undergoing Rayleigh Bénard convection. The apparatus was validated by observing convection rolls in 5cSt polydimethylsiloxane (PDMS) polymer fluid. Our first objective, after having built the apparatus, was to use it to study the sequence of transitions from diffusive to time--dependent heat transport in liquid mercury. The aim was to provide important information on pattern formation in the largely unexplored regime of very low Prandtl number fluids. Based on the theoretical stability diagram for liquid mercury, we anticipated that straight rolls should be stable over a range of Rayleigh numbers, between 1708 and approximately 1900. Though some of our power spectral densities were suggestive of the existence of weak convection, we have been unable to unambiguously visualize stable convection rolls above the theoretical onset of convection in liquid mercury. Currently, we are seeking ways to increase the sensitivity of our apparatus, such …

Check 21 Act: Most Consumers Have Accepted and Banks Are Progressing Toward Full Adoption of Check Truncation (open access)

Check 21 Act: Most Consumers Have Accepted and Banks Are Progressing Toward Full Adoption of Check Truncation

A letter report issued by the Government Accountability Office with an abstract that begins "Although check volume has declined, checks still represent a significant volume of payments that need to be processed, cleared, and settled. The Check Clearing for the 21st Century Act of 2003 (Check 21) was intended to make check collection more efficient and less costly by facilitating wider use of electronic check processing. It authorized a new legal instrument--the substitute check--a paper copy of an image of the front and back of the original check. Check 21 facilitated electronic check processing by allowing banks to use electronic imaging technology for collection and create substitute checks from those images for delivery to banks that do not accept checks electronically. Check 21 mandated that GAO evaluate the implementation and administration of the act. The report objectives are to (1) determine the gains in economic efficiency from check truncation and evaluate the benefits and costs to the Federal Reserve System (Federal Reserve) and financial institutions; (2) assess consumer acceptance of the check truncation process resulting from Check 21; and (3) evaluate the benefits and costs to bank consumers from check truncation. GAO analyzed costs for the check operations of the …

Development of a Composite Non-Electrostatic Surface Complexation Model Describing Plutonium Sorption to Aluminosilicates (open access)

Development of a Composite Non-Electrostatic Surface Complexation Model Describing Plutonium Sorption to Aluminosilicates

Due to their ubiquity in nature and chemical reactivity, aluminosilicate minerals play an important role in retarding actinide subsurface migration. However, very few studies have examined Pu interaction with clay minerals in sufficient detail to produce a credible mechanistic model of its behavior. In this work, Pu(IV) and Pu(V) interactions with silica, gibbsite (Aloxide), and Na-montmorillonite (smectite clay) were examined as a function of time and pH. Sorption of Pu(IV) and Pu(V) to gibbsite and silica increased with pH (4 to 10). The Pu(V) sorption edge shifted to lower pH values over time and approached that of Pu(IV). This behavior is apparently due to surface mediated reduction of Pu(V) to Pu(IV). Surface complexation constants describing Pu(IV)/Pu(V) sorption to aluminol and silanol groups were developed from the silica and gibbsite sorption experiments and applied to the montmorillonite dataset. The model provided an acceptable fit to the montmorillonite sorption data for Pu(V). In order to accurately predict Pu(IV) sorption to montmorillonite, the model required inclusion of ion exchange. The objective of this work is to measure the sorption of Pu(IV) and Pu(V) to silica, gibbsite, and smectite (montmorillonite). Aluminosilicate minerals are ubiquitous at the Nevada National Security Site and improving our understanding …

The Earned Income Tax Credit (EITC): Changes for 2008 and 2009 (open access)

The Earned Income Tax Credit (EITC): Changes for 2008 and 2009

The earned income tax credit established in the tax code in 1975, provides cash assistance to lower-income working parents and individuals through the tax system. The earned income tax credit for some earned income credit recipients will be higher in 2009 than it was in 2008. An increase in the size of the earned income tax credit will occur because the maximum amount of earned income used to calculate the credit and the phase-out income level are indexed for inflation.

Energy and system size dependence of phi meson production in Cu+Cu and Au+Au collisions (open access)

Energy and system size dependence of phi meson production in Cu+Cu and Au+Au collisions

We study the beam-energy and system-size dependence of {phi} meson production (using the hadronic decay mode {phi} {yields} K{sup +}K{sup -}) by comparing the new results from Cu + Cu collisions and previously reported Au + Au collisions at {radical}s{sub NN} = 62.4 and 200 GeV measured in the STAR experiment at RHIC. Data presented are from midrapidity (|y| < 0.5) for 0.4 < p{sub T} < 5 GeV/c. At a given beam energy, the transverse momentum distributions for {phi} mesons are observed to be similar in yield and shape for Cu + Cu and Au + Au colliding systems with similar average numbers of participating nucleons. The {phi} meson yields in nucleus-nucleus collisions, normalized by the average number of participating nucleons, are found to be enhanced relative to those from p + p collisions with a different trend compared to strange baryons. The enhancement for {phi} mesons is observed to be higher at {radical}s{sub NN} = 200 GeV compared to 62.4 GeV. These observations for the produced {phi}(s{bar s}) mesons clearly suggest that, at these collision energies, the source of enhancement of strange hadrons is related to the formation of a dense partonic medium in high energy nucleus-nucleus collisions …

Genetic analysis of the regulation of TCH gene expression, Final Report (open access)

Genetic analysis of the regulation of TCH gene expression, Final Report

The Arabidopsis TCH genes, originally isolated as a consequence of their upregulation in response to the mechanical stimulus of touch, are also upregulated by a variety of seemingly disparate environmental and hormonal stimuli. To gain insight into the complexities of TCH gene regulation, a number of approaches were taken. Regulatory elements responsible for regulation were identified and characteristics of the regulation were evaluated. Reporter genes were used to monitor expression localization and dynamics. Microarray analyses of genome-wide expression behavior indicated that touch-inducible gene expression is more widespread than generally appreciated. Identification of all touch-regulated genes shed light on the types of cellular processes that may be altered in response to mechanical stress perturbations. Expression of the TCH2 gene, also called CML24, encoding a calmodulin (CaM)-like (CML) protein, was evaluated. CML24 shares over 40% amino acid sequence identity with CaM, has 4 EF hands and undergoes a Ca2+-dependent change in migration rate through denaturing gel electrophoresis, indicating that CML24 binds Ca2+ and, as a consequence, undergoes conformational changes. CML24 expression occurs in all major organs and is induced from 2- to 15-fold in plants subjected to touch, darkness, heat, cold, hydrogen peroxide, abscisic acid (ABA) and indole-3-acetic acid. The putative CML24 …
