Acoustical Imaging and Mechanical Properties of Soft Rock and Marine Sediments Progress Report: October-December 2001

Description: During this phase of the project the research team concentrated on acquisition of acoustic emission data from the high porosity rock samples. The initial experiments indicated that the acoustic emission activity from high porosity Danian chalk were of a very low amplitude. Even though the sample underwent yielding and significant plastic deformation the sample did not generate significant AE activity. This was somewhat surprising. These initial results call into question the validity of attempt… more

Customs Service: Effects of Proposed Legislation on Officers' Pay

Description: A letter report issued by the General Accounting Office with an abstract that begins "GAO reviewed the effects of proposed legislation--H.R. 1833--on the pay of officers at the U.S. Customs Service. The proposal would amend the 1911 Act governing Customs officers' overtime and premium pay, and it would more closely align Customs differential pay with that of other federal agencies. Should the provision be enacted, Customs officers would be limited to the amount and times for which they would be… more

Energetic Particle Effects Can Explain the Low Frequency of Alfvin Modes in the DIII-D Tokamak

Description: During beam injection in the DIII-D tokamak, modes with lower frequencies than expected for toroidicity-induced Alfvin eigenmodes (TAE) are often observed. We present the analysis of one of these ''beta-induced Alfvin eigenmodes'' (BAE) with a high-n stability code HINST that includes the effect of the energetic ions on the mode frequency. It shows that the ''BAE'' could be the theoretically predicted resonant-TAE (RTAE), which is also called an energetic-particle mode (EPM).

Fish and Wildlife Service: Challenges to Managing the Carlsbad, California, Field Office's Endangered Species Workload

Description: A letter report issued by the General Accounting Office with an abstract that begins "The Fish and Wildlife Service's (FWS) Carlesbad office is developing a computerized project-tracking system for its consultation and habitat conservation planning (HCP) projects. This system, if properly implemented, should improve the office's record keeping and its ability to track the status of projects and help determine why they are in that status. The new system could also improve project management by a… more

Food Safety: Federal Oversight of Seafood Does Not Sufficiently Protect Consumers

Description: A letter report issued by the General Accounting Office with an abstract that begins "Since the Food and Drug Administration (FDA) issued the Hazard Analysis and Critical Control Point system (HACCP) regulations for seafood, the food industry has made some progress in ensuring the safety of seafood. However, several important weaknesses compromise the overall effectiveness of the federal seafood safety system. If left uncorrected, they will continue to undermine the goal of HACCP systems--that … more

In-Situ Electrolyte Replenishment for Long Fuel Cell Life. Phase II Final Report

Description: The carbonate fuel cell has many advantages over conventional methods of producing electricity. It converts hydrocarbon fuels directly into electricity with a high efficiency (>70% in a co-generation plant configuration) and consequently releases less carbon dioxide greenhouse gases (>30% less compared to a combined cycle gas turbine plant). Its adaptability to meet the customers' specific power requirements is ideally suited for distributed power generation. The advantages of distributed… more

LDV Measurement of Confined Parallel Jet Mixing

Description: Laser Doppler Velocimetry (LDV) measurements were taken in a confinement, bounded by two parallel walls, into which issues a row of parallel jets. Two-component measurements were taken of two mean velocity components and three Reynolds stress components. As observed in isolated three dimensional wall bounded jets, the transverse diffusion of the jets is quite large. The data indicate that this rapid mixing process is due to strong secondary flows, transport of large inlet intensities and Reynol… more

Motor Vehicle Safety: NHTSA's Ability to Detect and Recall Defective Replacement Crash Parts Is Limited

Description: A letter report issued by the General Accounting Office with an abstract that begins "Although the National Highway Traffic Safety Administration (NHTSA) has the authority to regulate aftermarket crash parts, the agency has not developed safety standards for them because it has not determined that any aftermarket crash parts contain safety-related defects. NHTSA has more limited authority to regulate the use of recycled air bags. NHTSA could elect to develop safety standards for occupant restra… more
