Aviation Safety: FAA Needs to Strengthen the Management of Its Designee Programs

Description: A letter report issued by the Government Accountability Office with an abstract that begins "The safety of the flying public and the reliability of the nation's aircraft depend, in part, on the Federal Aviation Administration's (FAA) regulation and certification of the aviation industry. FAA delegates the vast majority of its safety certification activities to about 13,600 private persons and organizations, known as "designees," which are currently grouped into 18 different programs. Among othe… more

Medicare Physician Payments: Concerns about Spending Target System Prompt Interest in Considering Reforms

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Concerns were raised about the current system Medicare uses to determine annual changes to physician fees--the sustainable growth rate (SGR) system--when fees were reduced by 5.4 percent in 2002. Subsequent administrative and legislative actions modified or overrode the SGR system, resulting in fee increases for 2003, 2004, and 2005. However, projected fee reductions for 2006-2012 have raised new concer… more

Immigration Enforcement: DHS Has Incorporated Immigration Enforcement Objectives and Is Addressing Future Planning Requirements

Description: A letter report issued by the Government Accountability Office with an abstract that begins "The former Immigration and Naturalization Service (INS) had five interior (non-border-related) immigration enforcement objectives to address federal immigration law violations: identify and remove criminal aliens from the United States; deter and dismantle alien trafficking and smuggling; respond to community reports and complaints about illegal immigration; minimize immigration benefit fraud; and block… more

Defects in p-GaN and their atomic structure

Description: In this paper defects formed in p-doped GaN:Mg grown with Ga polarity will be discussed. The atomic structure of these characteristic defects (Mg-rich hexagonal pyramids and truncated pyramids) in bulk and thin GaN:Mg films grown with Ga polarity was determined at atomic resolution by direct reconstruction of the scattered electron wave in a transmission electron microscope. Small cavities were present inside the defects. The inside walls of the cavities were covered by GaN which grew with reve… more

Study of Dark Matter inspired cMSSM scenarios at a TeV-class Linear Collider

Description: The accuracy in the measurement of the masses of sleptons and heavy Higgs bosons in cMSSM scenarios, compatible with the WMAP result on cold dark matter, has been re-analysed in view of the requirements for predicting this density to a few percent level from SUSY measurements at the linear collider.

Fabrication and Characterization of Graded Cu-Doped Be Shells - Details and Documentation of Our First Attempt

Description: We have fabricated by sputtering and characterized a set of step-graded Cu-doped Be capsules. The capsules were made with Cu doped layers of about 0.35 and 0.70 atom % Cu. The total thickness of the coating is about 100 {micro}m. Capsules were removed from the coater for characterization after each layer was deposited. Our ability to produce doped layers is confirmed, and our ability to control the level of doping is excellent. A variety of characterization techniques, both destructive and non-… more

Water-Level Data Analysis for the Saturated Zone Site-Scale Flow and Transport Model

Description: This report is an updated analysis of water-level data performed to provide the ''Saturated Zone Site-Scale Flow Model'' (BSC 2004 [DIRS 170037]) (referred to as the saturated zone (SZ) site-scale flow model or site-scale SZ flow model in this report) with the configuration of the potentiometric surface, target water-level data, and hydraulic gradients for calibration of groundwater flow models. This report also contains an expanded discussion of uncertainty in the potentiometric-surface map. T… more

Aqueous Corrosion Rates for Waste Package Materials

Description: The purpose of this analysis, as directed by ''Technical Work Plan for: Regulatory Integration Modeling and Analysis of the Waste Form and Waste Package'' (BSC 2004 [DIRS 171583]), is to compile applicable corrosion data from the literature (journal articles, engineering documents, materials handbooks, or standards, and national laboratory reports), evaluate the quality of these data, and use these to perform statistical analyses and distributions for aqueous corrosion rates of waste package ma… more

Aspects of C-H Activation in Metal Complexes Containing Sulfur Ligands

Description: The research project proposed to synthesize new metal complexes with sulfido, disulfido and other types of reactive sulfur ligands, and to explore the joint reactivity of metal and sulfur ligands with hydrogen and organic molecules. The overall objective was to investigate reaction pathways relevant to those observed for the heterogeneous metal sulfide catalysts which promote hydrogen activation, hydrogenation-dehydrogenation of organic substrates, and hydrogenolysis of carbon-heteroatom bonds.… more

Effect of Aging on the Toughness of Human Cortical Bone: Evaluation by R-Curves

Description: Age-related deterioration of the fracture properties of bone, coupled with increased life expectancy, are responsible for increasing incidence of bone fracture in the elderly, and hence, an understanding of how its fracture properties degrade with age is essential. The present study describes ex vivo fracture experiments to quantitatively assess the effect of aging on the fracture toughness properties of human cortical bone in the longitudinal direction. Because cortical bone exhibits rising cr… more

The Ags-Based Super Neutrino Beam Facility Conceptual Design Report

Description: After more than 40 years of operation, the AGS is still at the heart of the Brookhaven hadron accelerator complex. This system of accelerators presently comprises a 200 MeV linac for the pre-acceleration of high intensity and polarized protons, two Tandem Van der Graaffs for the pre-acceleration of heavy ion beams, a versatile Booster that allows for efficient injection of all three types of beams into the AGS and, most recently, the two RHIC collider rings that produce high luminosity heavy io… more

An Orientation Distribution Function for Trabecular Bone

Description: We describe a new method for quantifying the orientation of trabecular bone from three-dimensional images. Trabecular lattices from five human vertebrae were decomposed into individual trabecular elements, and the orientation, mass, and thickness of each element were recorded. Continuous functions that described the total mass (M({var_phi},{theta})) and mean thickness ({tau}({var_phi},{theta})) of all trabeculae as a function of orientation were derived. The results were compared with experimen… more

Clocking Femtosecond X-Rays

Description: The Sub-Picosecond Pulse Source (SPPS) at the Stanford Linear Accelerator Center (SLAC) produces the brightest ultrafast x-ray pulses in the world, and is the first to employ compressed femtosecond electron bunches for the x-ray source. Both SPPS and future X-ray Free Electron Lasers (XFEL's) will use precise measurements of individual electron bunches to time the arrival of x-ray pulses for time-resolved experiments. At SPPS we use electro-optic sampling (EOS) to perform these measurements. He… more
