Adaptive Optics Imaging Survey of Luminous Infrared Galaxies (open access)

Adaptive Optics Imaging Survey of Luminous Infrared Galaxies

We present high resolution imaging observations of a sample of previously unidentified far-infrared galaxies at z < 0.3. The objects were selected by cross-correlating the IRAS Faint Source Catalog with the VLA FIRST catalog and the HST Guide Star Catalog to allow for adaptive optics observations. We found two new ULIGs (with L{sub FIR} {ge} 10{sup 12} L{sub {circle_dot}}) and 19 new LIGs (with L{sub FIR} {ge} 10{sup 11} L{sub {circle_dot}}). Twenty of the galaxies in the sample were imaged with either the Lick or Keck adaptive optics systems in H or K{prime}. Galaxy morphologies were determined using the two dimensional fitting program GALFIT and the residuals examined to look for interesting structure. The morphologies reveal that at least 30% are involved in tidal interactions, with 20% being clear mergers. An additional 50% show signs of possible interaction. Line ratios were used to determine powering mechanism; of the 17 objects in the sample showing clear emission lines--four are active galactic nuclei and seven are starburst galaxies. The rest exhibit a combination of both phenomena.

Basic Data Report for Well Plugging and Abandonment and Reconfiguration Activities for Fiscal Year 2005 (open access)

Basic Data Report for Well Plugging and Abandonment and Reconfiguration Activities for Fiscal Year 2005

The FY 2005 program was initiated on March 31, 2005, and concluded on July 16, 2005. The FY 2005 program initially included 25 wells requiring workover (P&A, Magenta reconfiguration, cleaning and keeping). During the process, the U.S. Bureau of Land Management (BLM) requested transfer of two wells (H-7c and H-8c) to their ownership for future livestock watering. These wells were transferred to the BLM through execution of Form wr-03, Declaration of Owner of Underground Water Rights, between the New Mexico Office of the State Engineer (NMOSE), the BLM, and the DOE Carlsbad Field Office (CBFO). One well (H-2b2) was cleaned and retained as a Culebra monitor well for continued use. One well (H-3d) was converted to a shallow well to monitor the formational contact between the Dewey Lake Redbeds Formation and the Santa Rosa Formation in support of the DP-831 discharge permit monitoring program. Nine dual-completion wells were reconfigured as Magenta-only monitor wells, and 12 wells were plugged and abandoned permanently. This report presents the summary in the same order that the wells were worked in the field.

China, the United States and the IMF: Negotiating Exchange Rate Adjustment (open access)

China, the United States and the IMF: Negotiating Exchange Rate Adjustment

In recent years, the United States and other countries have expressed considerable concern that China’s national currency (the yuan or renminbi) is seriously undervalued. Some analysts say the yuan needs to rise by as much as 40% in order to reflect its equilibrium value. Critics say that China’s undervalued currency provides it with an unfair trade advantage that has seriously injured the manufacturing sector in the United States. Chinese officials counter that they have not pegged the yuan to the dollar in order to gain trade advantages. Rather, they say the fixed rate promotes economic stability that is vital for the functioning of its domestic economy.

Comparison of Experimental to Theoretical Strains During Water Hammer (open access)

Comparison of Experimental to Theoretical Strains During Water Hammer

Experimental strains during water hammer were compared to theoretical equations for strain. These equations were derived from the basic equations of motion, which lead to equations for the hoop stress and hoop strain. In this particular case, a sudden pressure increase increase traveling in a pipe was measured, and the hoop strains resulting from this fluid transient were also measured. Measuring the strains at numerous locations along the pipe permitted comparison of the strains as a function of position with respect to the fluid shock wave. This comparison of strains at different positions along the pipe permits analysis the vibratory nature of the strain in the pipe wall. Essentially, the equations of motion provide an approximate technique to find the maximum stress and strain due to water hammer.

Controlled VLS Growth of Indium, Gallium and Tin Oxide Nanowiresvia Chemical Vapor Transport (open access)

Controlled VLS Growth of Indium, Gallium and Tin Oxide Nanowiresvia Chemical Vapor Transport

We utilized a vapor-liquid-solid growth technique to synthesize indium oxide, gallium oxide, and tin oxide nanowires using chemical vapor transport with gold nanoparticles as the catalyst. Using identical growth parameters we were able to synthesize single crystal nanowires typically 40-100 nm diameter and more than 10-100 microns long. The products were characterized by means of XRD, SEM and HRTEM. All the wires were grown under the same growth conditions with growth rates inversely proportional to the source metal vapor pressure. Initial experiments show that different transparent oxide nanowires can be grown simultaneously on a single substrate with potential application for multi-component gas sensors.

Femtosecond Diffractive Imaging with a Soft-X-ray Free-Electron Laser (open access)

Femtosecond Diffractive Imaging with a Soft-X-ray Free-Electron Laser

Theory predicts that with an ultrashort and extremely bright coherent X-ray pulse, a single diffraction pattern may be recorded from a large macromolecule, a virus, or a cell before the sample explodes and turns into a plasma. Here we report the first experimental demonstration of this principle using the FLASH soft X-ray free-electron laser. An intense 25 fs, 4 x 10{sup 13} W/cm{sup 2} pulse, containing 10{sup 12} photons at 32 nm wavelength, produced a coherent diffraction pattern from a nano-structured non-periodic object, before destroying it at 60,000 K. A novel X-ray camera assured single photon detection sensitivity by filtering out parasitic scattering and plasma radiation. The reconstructed image, obtained directly from the coherent pattern by phase retrieval through oversampling, shows no measurable damage, and extends to diffraction-limited resolution. A three-dimensional data set may be assembled from such images when copies of a reproducible sample are exposed to the beam one by one.

Homosexuals and U.S. Military Policy: Current Issues (open access)

Homosexuals and U.S. Military Policy: Current Issues

This report discusses policy towards homosexuals in the U.S. military service. In 1993, new laws and regulations pertaining to homosexuals and U.S. military service came into effect reflecting a compromise in policy. This compromise, colloquially referred to as “don’t ask, don’t tell,” holds that the presence in the armed forces of persons who demonstrate a propensity or intent to engage in homosexual acts would create an unacceptable risk to the high standards of morale, good order and discipline, and unit cohesion which are the essence of military capability. Service members are not to be asked about nor allowed to discuss their homosexuality. This compromise notwithstanding, the issue has remained politically contentious.

Lanczos and Recursion Techniques for Multiscale Kinetic Monte Carlo Simulations (open access)

Lanczos and Recursion Techniques for Multiscale Kinetic Monte Carlo Simulations

We review an approach to the simulation of the class of microstructural and morphological evolution involving both relatively short-ranged chemical and interfacial interactions and long-ranged elastic interactions. The calculation of the anharmonic elastic energy is facilitated with Lanczos recursion. The elastic energy changes affect the rate of vacancy hopping, and hence the rate of microstructural evolution due to vacancy mediated diffusion. The elastically informed hopping rates are used to construct the event catalog for kinetic Monte Carlo simulation. The simulation is accelerated using a second order residence time algorithm. The effect of elasticity on the microstructural development has been assessed. This article is related to a talk given in honor of David Pettifor at the DGP60 Workshop in Oxford.

Localized Corrosion Behavior of Type 304SS with a Silica Layer Under Atmospheric Corrosion Environments (open access)

Localized Corrosion Behavior of Type 304SS with a Silica Layer Under Atmospheric Corrosion Environments

The U.S. Department of Energy (DOE) has proposed a potential repository for spent nuclear fuel and high-level radioactive waste at the Yucca Mountain site in Nevada. [I] The temperature could be high on the waste packages, and it is possible that dripping water or humidity could interact with rock dust particulate to form a thin electrolyte layer with concentrated ionic species. Under these conditions, it is possible that highly corrosion-resistant alloys (CRAs) used as packages to dispose the nuclear waste could suffer localized corrosion. Therefore, to better understand long-term corrosion performance of CRAs in the repository, it is important to investigate localized corrosion under a simulated repository environment. We measured open circuit potential (OCP) and galvanic current (i{sub g}) for silica-coated Type 304SS during drying of salt solutions under controlled RH environments to clarify the effect of silica layer as a dust layer simulant on localized corrosion under atmospheric environments. Type 304SS was used as a relatively susceptible model CRA instead of the much more corrosion resistant alloys, such as Alloy 22, that are being considered as, waste package materials.

Measurements of Intra-Beam Scattering at Low Emittance in the Advanced Light Source (open access)

Measurements of Intra-Beam Scattering at Low Emittance in the Advanced Light Source

The beam emittance at the interaction point of linear colliders is expected to be strongly influenced by the emittance of the beams extracted from the damping rings. Intra-beam scattering (IBS) potentially limits the minimum emittance of low-energy storage rings, and this effect strongly influences the choice of energy of damping rings [1]. Theoretical analysis suggests that the NLC damping rings will experience modest emittance growth at 1.98 GeV, however there is little experimental data of IBS effects for very low-emittance machines in the energy regime of interest. The Advanced Light Source (ALS) at Lawrence Berkeley National Laboratory is a third-generation synchrotron light source operating with high-intensity, low-emittance beams at energies of approximately 1-2 GeV, and with emittance coupling capability of 1% or less. We present measurements of the beam growth in three dimensions as a function of current, for normalized natural horizontal emittance of approximately 1-10 mm-mrad at energies of 0.7-1.5 GeV, values comparable to the parameters in an NLC damping ring. Using a dedicated diagnostic beamline with an x-ray scintillator imaging system, measurements of the transverse beamsize are made, and bunch length measurements are made using an optical streak camera. Emittance growth as a function of bunch current is …
