Analysis of micro-structural relaxation phenomena in laser-modified fused silica using confocal Raman microscopy
Fused silica micro-structural changes associated with localized 10.6 {micro}m CO{sub 2} laser heating are reported. Spatially-resolved shifts in the high-frequency asymmetric stretch transverse-optic (TO) phonon mode of SiO{sub 2} were measured using confocal Raman microscopy, allowing construction of axial fictive temperature (T{sub f}) maps for various laser heating conditions. A Fourier conduction-based finite element model was employed to compute on-axis temperature-time histories, and, in conjunction with a Tool-Narayanaswamy form for structural relaxation, used to fit T{sub f}(z) profiles to extract relaxation parameters. Good agreement between the calculated and measured T{sub f} was found, yielding reasonable values for relaxation time and activation enthalpy in the laser-modified silica.

Celebrating 100 Years of the Texas Folklore Society, 1909-2009
The Texas Folklore Society is one of the oldest and most prestigious organizations in the state. Its secret for longevity lies in those things that make it unique, such as its annual meeting that seems more like a social event or family reunion than a formal academic gathering. This book examines the Society’s members and their substantial contributions to the field of folklore over the last century. Some articles focus on the research that was done in the past, while others offer studies that continue today. For example, L. Patrick Hughes explores historical folk music, while Meredith Abarca focuses on Mexican American folk healers and the potential direction of research on them today. Other articles are more personal reflections about why our members have been drawn to the TFS for fellowship and fun. This book does more than present a history of the Texas Folklore Society: it explains why the TFS has lasted so long, and why it will continue.

Control Banding and Nanotechnology Synergist
The average Industrial Hygienist (IH) loves a challenge, right? Okay, well here is one with more than a few twists. We start by going through the basics of a risk assessment. You have some chemical agents, a few workers, and the makings of your basic exposure characterization. However, you have no occupational exposure limit (OEL), essentially no toxicological basis, and no epidemiology. Now the real handicap is that you cannot use sampling pumps, cassettes, tubes, or any of the media in your toolbox, and the whole concept of mass-to-dose is out the window, even at high exposure levels. Of course, by the title, you knew we were talking about nanomaterials (NM). However, we wonder how many IHs know that this topic takes everything you know about your profession and turns it upside down. It takes the very foundations that you worked so hard in college and in the field to master and pulls it out from underneath you. It even takes the gold standard of our profession, the quantitative science of exposure assessment, and makes it look pretty darn rusty. Now with NM there is the potential to get some aspect of quantitative measurements, but the instruments are generally very …

Department of Homeland Security: A Comprehensive Strategy Is Still Needed to Achieve Management Integration Departmentwide
Testimony issued by the Government Accountability Office with an abstract that begins "Significant management challenges exist for the Department of Homeland Security (DHS) as it continues to integrate its varied management processes, policies, and systems in areas such as financial management and information technology. These activities are primarily led by the Under Secretary for Management (USM), department management chiefs, and management chiefs in DHS's seven components. This testimony summarizes a new GAO report (GAO-10-131) that examined (1) the extent to which DHS has developed a comprehensive strategy for management integration that includes the characteristics recommended in GAO's earlier 2005 report, (2) how DHS is implementing management integration, and (3) the extent to which the USM is holding the department and component management chiefs accountable for implementing management integration through reporting relationships. GAO reviewed DHS plans and interviewed DHS management officials."

Fabrication and characterization of submicron polymer waveguides by micro-transfer molding
Various methods exist for fabrication of micron and submicron sized waveguide structures. However, most of them include expensive and time consuming semiconductor fabrication techniques. An economical method for fabricating waveguide structures is introduced and demonstrated in this thesis. This method is established based on previously well-developed photonic crystal fabrication method called two-polymer microtransfer molding. The waveguide in this work functions by a coupler structure that diffracts the incident light into submicron polymer rods. The light is then guided through the rods. Characterization is done by collecting the light that has been guided through the waveguide and exits the end of these submicron polymer bars. The coupling and waveguiding capabilities are demonstrated using two light sources, a laser and white light.

Formula Grants: Funding for the Largest Federal Assistance Programs Is Based on Census-Related Data and Other Factors
A letter report issued by the Government Accountability Office with an abstract that begins "Many federal assistance programs are funded by formula grants that have historically relied at least in part on population data from the decennial census and related data to allocate funds. In June 2009, the Census Bureau reported that in fiscal year 2007 the federal government obligated over $446 billion through funding formulas that rely at least in part on census and related data. Funding for federal assistance programs continues to increase. Government Accountability Office (GAO) was asked to determine (1) how much the federal government obligates to the largest federal assistance programs based on the decennial census and related data, and how the Recovery Act changed that amount; and (2) what factors could affect the role of population in grant funding formulas. To answer these objectives, GAO identified the 10 largest federal assistance programs in each of the fiscal years 2008 and 2009 based on data from the President's fiscal year 2010 budget. GAO reviewed statutes, agency reports, and other sources to obtain illustrative examples of how different factors could affect the role of population data in grant funding."

Hydrated goethite (alpha-FeOOH) (100) interface structure: Ordered water and surface functional groups.
Goethite({alpha}-FeOOH), an abundant and highly reactive iron oxyhydroxide mineral, has been the subject of numerous stud-ies of environmental interface reactivity. However, such studies have been hampered by the lack of experimental constraints on aqueous interface structure, and especially of the surface water molecular arrangements. Structural information of this type is crucial because reactivity is dictated by the nature of the surface functional groups and the structure or distribution of water and electrolyte at the solid-solution interface. In this study we have investigated the goethite(100) surface using surface diffraction techniques, and have determined the relaxed surface structure, the surface functional groups, and the three dimensional nature of two distinct sorbed water layers. The crystal truncation rod (CTR) results show that the interface structure consists of a double hydroxyl, double water terminated interface with significant atom relaxations. Further, the double hydroxyl terminated surface dominates with an 89% contribution having a chiral subdomain structure on the(100) cleavage faces. The proposed interface stoichiometry is ((H{sub 2}O)-(H{sub 2}O)-OH{sub 2}-OH-Fe-O-O-Fe-R) with two types of terminal hydroxyls; a bidentate (B-type) hydroxo group and a monodentate (A-type) aquo group. Using the bond-valence approach the protonation states of the terminal hydroxyls are predicted to be OH type (bidentate hydroxyl …

An Introduction to the Design of the Low-Income Housing Tax Credit
This report discusses the Low-Income Housing Tax Credit (LIHTC), which is a federal provision that reduces the income tax liability of taxpayers claiming the credit. These taxpayers are typically investors in real estate development projects that have traded cash for the tax credits to support the production of affordable housing. The credit is intended to lower the financing costs of housing developments so that the rental prices of units can be lower than market rates, and thus, presumably, affordable.

Managing Sensitive Information: Actions Needed to Prevent Unintended Public Disclosures of U.S. Nuclear Sites and Activities
A letter report issued by the Government Accountability Office with an abstract that begins "On May 7, 2009, the Government Printing Office (GPO) published a 266-page document on its Web site that provided detailed information on civilian nuclear sites, locations, facilities, and activities in the United States. At the request of the Speaker of the House, this report determines (1) which U.S. agencies were responsible for the public release of this information and why the disclosure occurred, and (2) what impact, if any, the release of the information has had on U.S. national security. In performing this work, the Government Accountability Office (GAO) analyzed policies, procedures, and guidance for safeguarding sensitive information and met with officials from four executive branch agencies involved in preparing the document, the White House, the House of Representatives, and GPO."

Novel Low Temperature Solid State Fuel Cells
We have successfully fabricated (PrBa)Co{sub 2}O{sub 5+{delta}} and (LaBa)Co{sub 2}O{sub 5+{deleta}} epitaxial thin film on various single crystal substrates. Physical and electrochemical properties characterizations were carried out. Highly conductive oxygen-deficient double perovskite LnBaCo2O5+? thin films were grown on single crystal (001) SrTiO{sub 3} (STO), (001) MgO, (001) LaAlO{sub 3} and (110) NdGaO{sub 3} substrate by pulsed laser deposition. Microstructure studies from synchrotron X-ray diffraction and Transmission electron microscopy. High temperature transport properties was carried in different atmosphere (O{sub 2},Air, N{sub 2}) up to ~900K. Resistance response of (LaBa)Co{sub 2}O{sub 5+{delta}} epitaxial thin film was characterized in oxygen, nitrogen and 4% hydrogen over a wide range of temperature from 400�C up to 800�C. To determine the electrode performance and oxygen exchange kinetics of PrBaCo{sub 2}O{sub 5+{delta}}, multi-layered thin film based half cell was deposited on LaAlO{sub 3}(001) substrate. The temperature dependence of the resistance of this half ?cell structure was characterized by electrochemical impedance spectroscopy (EIS) within different temperature and gas environments. Anode supported fuel cells, with GCO:YSZ multilayer thin film as electrolyte and PBCO thin film as electrode, are fabricated on tape casted NiO/YSZ substrate. Full cell performance is characterized up to 800�C.

Observation of Strong Resonant Behavior in the Inverse Photoelectron Spectroscopy of Ce Oxide
X-ray Emission Spectroscopy (XES) and Resonant Inverse Photoelectron Spectroscopy (RIPES) have been used to investigate the photon emission associated with the Ce3d5/2 and Ce3d3/2 thresholds. Strong resonant behavior has been observed in the RIPES of Ce Oxide near the 5/2 and 3/2 edges. Inverse Photoelectron Spectroscopy (IPES) and its high energy variant, Bremstrahlung Isochromat Spectroscopy (BIS), are powerful techniques that permit a direct interrogation of the low-lying unoccupied electronic structure of a variety of materials. Despite being handicapped by counting rates that are approximately four orders of magnitude less that the corresponding electron spectroscopies (Photoelectron Spectroscopy, PES, and X-ray Photoelectron Spectroscopy, XPS) both IPES and BIS have a long history of important contributions. Over time, an additional variant of this technique has appeared, where the kinetic energy (KE) of the incoming electron and photon energy (hv) of the emitted electron are roughly the same magnitude as the binding energy of a core level of the material in question. Under these circumstances and in analogy to Resonant Photoelectron Spectroscopy, a cross section resonance can occur, giving rise to Resonant Inverse Photoelectron Spectroscopy or RIPES. Here, we report the observation of RIPES in an f electron system, specifically the at the 3d{sub …
