Davis-Bacon Act: Labor Now Verifies Wage Data, but Verification Process Needs Improvement

Description: A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a legislative requirement, GAO reviewed the: (1) Department of Labor's response to the House Appropriations Committee's directive that it verify a random sample of employers' wage data submissions and select a sample of submissions for on-site data verification; and (2) likely effect of these efforts on the accuracy and timeliness of Davis-Bacon Act wage determinations."

Point Defects in Binary Laves-Phase Alloys

Description: Point defects in the binary C15 NbCrQ and NbCoz, and C 14 NbFe2 systems on both sides of stoichiometry were studied by both bulk density and X-ray Iattiee parameter measurements. It was found that the vacancy concentrations in these systems after quenching from 1000"C are essentially zero. The constitutional defects on both sides of stoichiometry for these systems were found to be of the anti-site type in comparison with the model predictions. Thermal vacancies exhibiting a maximum at the stoic… more

House Committee Markup: Preparation

Description: Markups provide Members on a committee an opportunity to change parts of a bill prior to its consideration by the full House. A number of administrative, procedural, and substantive steps must be undertaken in preparation for a markup, and other steps could or should be undertaken. Generally, the markup should be strategically planned to minimize controversy, provide Members with political dividends, and position the committee for future action. This report is intended as a guide for various ta… more

House Committee Markup: Reporting

Description: At the end of the amendment process, the chair normally entertains a motion to report a measure favorably to the House. This report addresses the procedural options committees have regarding the form of reporting, such as what happens to amendments adopted in markup, as well as other considerations at the time of reporting.

House Committee Markup: Amendment Procedure

Description: This report briefly discusses committee markups in the House of Representatives. The essential purpose of a committee markup is to determine whether a measure pending before a committee should be altered, or amended, in any substantive way. Of course, committees do not actually amend measures; instead a committee votes on which amendments it wishes to recommend to the House.

Transport, Growth Mechanisms, and Material Quality in GaN Epitaxial Lateral Overgrowth

Description: Growth kinetics, mechanisms, and material quality in GaN epitaxial lateral over-growth (ELO) were examined using a single mask of systematically varied patterns. A 2-D gas phase reaction/diffusion model describes how transport of the Ga precursor to the growth surface enhances the lateral rate in the early stages of growth. In agreement with SEM studies of truncated growth runs, the model also predicts the dramatic decrease in the lateral rate that occurs as GaN over-growth reduces the exposed … more

Optical Detection of Aqueous Phase Analytes via Host-Guest Interactions on a Lipid Membrane Surface

Description: The organization and assembly of molecules in cellular membranes is orchestrated through the recognition and binding of specific chemical signals. A simplified version of the cellular membrane system has been developed using a synthetically prepared membrane receptor incorporated into a biologically derived lipid bilayer. Through an interplay of electrostatic and van der Wards interactions, aggregation or dispersion of molecular components could be executed on command using a specific chemical … more

Cycling Endurance of SONOS Non-Volatile Memory Stacks Prepared with Nitrided SiO(2)/Si(100) Intefaces

Description: The effects of nitrided SiO{sub 2}/Si(100) interfaces upon cycling endurance in silicon-oxide-nitride-oxide-silicon (SONOS) non-volatile memory transistors are investigated. Analysis of MOSFET sub-threshold characteristics indicate cycling degradation to be a manifestation of interface state (D{sub it}) generation at the tunnel oxide/silicon interface. After 10{sup 6} write/erase cycles, SONOS film stacks prepared with nitrided tunnel oxides exhibit enhanced cycling endurance with {Delta}D{sub … more

Deflection of large near-earth objects

Description: The Earth is periodically hit by near Earth objects (NEOs) ranging in size from dust to mountains. The small ones are a useful source of information, but those larger than about 1 km can cause global damage. The requirements for the deflection of NEOs with significant material strength are known reasonably well; however, the strength of large NEOs is not known, so those requirements may not apply. Meteor impacts on the Earth`s atmosphere give some information on strength as a function of object… more

Application of the Solubility Parameter Concept to the Design of Chemiresistor Arrays

Description: Arrays of unheated chemically sensitive resistors (chemiresistors) can serve as extremely small, low-power-consumption sensors with simple read-out electronics. We report here results on carbon-loaded polymer composites, as well as polymeric ionic conductors, as chemiresistor sensors. We use the volubility parameter concept to understand and categorize the chemiresistor responses and, in particular, we compare chemiresistors fabricated from polyisobutylene (PIB) to results from PIB-coated acous… more

Reflectance Infrared Spectroscopy on Operating Surface Acoustic Wave Chemical Sensors During Exposure to Gas-Phase Analytes

Description: We have developed instrumentation to enable the combination of surface acoustic wave (SAW) sensor measurements with direct, in-situ molecular spectroscopic measurements to understand the response of the SAW sensors with respect to the interfacial chemistry of surface-confined sensing films interacting with gas-phase analytes. Specifically, the instrumentation and software was developed to perform in-situ Fourier-transform infrared external-reflectance spectroscopy (FTIR-ERS) on operating SAW de… more

A Coupled Modeling System to Simulate Water Resources in the Rio Grande Basin

Description: Limited availability of fresh water in arid and semi-arid regions of the world requires prudent management strategies from accurate, science-based assessments. These assessments demand a thorough understanding of the hydrologic cycle over long time periods within the individual water-sheds that comprise large river basins. Measurement and simulation of the hydrologic cycle is a tremendous challenge, involving a coupling between global to regional-scale atmospheric precipitation processes with r… more

LANDFILL OPERATION FOR CARBON SEQUESTRATION AND MAXIMUM METHANE EMISSION CONTROL

Description: ''Conventional'' waste landfills emit methane, a potent greenhouse gas, in quantities such that landfill methane is a major factor in global climate change. Controlled landfilling is a novel approach to manage landfills for rapid completion of total gas generation, maximizing gas capture and minimizing emissions of methane to the atmosphere. With controlled landfilling, methane generation is accelerated and brought to much earlier completion by improving conditions for biological processes (pri… more

Reliability and Lifetime Prediction for Ceramic Components

Description: Ceramic materials are used extensively in non-nuclear components in the weapons stockpile including neutron tubes, stronglinks, weaklinks, batteries, and current/voltage stacks. Ceramics also perform critical functions in electronics, passively as insulators and actively as resistors and capacitors, Glass and ceramic seals also provide hermetic electrical feedthrus in connectors for many weapons components.

AN ADVANCED CONTROL SYSTEM FOR FINE COAL FLOTATION

Description: A model-based flotation control scheme is being implemented to achieve optimal performance in the handling and treatment of fine coal. The control scheme monitors flotation performance through on-line analysis of tailings ash content. Then, based on an on-line estimate of incremental ash, the pulp level is adjusted using a model-based control algorithm to compensate for feed variations and other process disturbances. Recent developments in sensor technology are being applied for on-line determi… more
