Laboratory Studies of the Effects of Pressure and Dissolved Gas Supersaturation on Turbine-Passed Fish

Description: The objective of this study was to examine the relative importance of pressure changes as a source of turbine-passage injury and mortality. Specific tests were designed to quantify the response of fish to rapid pressure changes typical of turbine passage, with and without the complication of the fish being acclimated to gas supersaturated water. We investigated the responses of rainbow trout (Oncorhynchus mykiss), chinook salmon (O. tshawytscha), and bluegill sunfish (Lepomis macrochirus) to th… more

Trade Legislation in the 106th Congress: An Overview

Description: The 106th Congress completed action on a number of major trade initiatives. The impact on American firms and workers was a paramount concern in the passage of this legislation. Most notably, bills were passed to establish "normal trade relations" with China, deepen economic ties with the countries of Sub-Saharan Africa, enhance trade benefits for 24 Caribbean Basin countries, and to ease trade sanctions on Cuba and other countries. Congress also voted to maintain U.S. participation in the World… more

A Search for the Higgs Boson Using Very Forward Tracking Detectors with CDF

Description: The authors propose to add high precision track detectors 55 m downstream on both (E and W) sides of CDF, to measure high Feynman-x protons and antiprotons in association with central states. A primary motivation is to search for the Higgs boson, and if it is seen to measure its mass precisely. The track detectors will be silicon strip telescopes backed up by high resolution time-of-flight counters. They will have four spectrometer arms, for both sides of the p and {bar p} beams. The addition o… more

Separation of co2 From Flue Gases by Carbon-Multiwall Carbon Nanotube Membranes

Description: Multiwalled carbon nanotubes (MWNT) were found to be an effective separation media for removing CO{sub 2} from N{sub 2}. The separation mechanism favors the selective condensation of CO{sub 2} from the flowing gas stream. Significant uptakes of CO{sub 2} were measured at 30 C and 150 C over the pressure range 0.5 to 5 bar. No measurable uptake of nitrogen was found for this range of conditions. The mass uptake of CO{sub 2} by MWNT was found to increase with increasing temperature. A packed bed … more

Seismic Characterization of Coal-Mining Seismicity in Utah for CTBT Monitoring

Description: Underground coal mining (down to {approx}0.75 km depth) in the contiguous Wasatch Plateau (WP) and Book Cliffs (BC) mining districts of east-central Utah induces abundant seismicity that is monitored by the University of Utah regional seismic network. This report presents the results of a systematic characterization of mining seismicity (magnitude {le} 4.2) in the WP-BC region from January 1978 to June 2000-together with an evaluation of three seismic events (magnitude {le} 4.3) associated with… more

White Paper on Proton - Nucleus Collisons.

Description: The role of proton-nucleus (p-A) collisions in the study of strong interactions has a long history. It has been an important testing ground for QCD. At RHIC p-A studies have been recognized since the beginning as important elements of the program. These include so-called baseline measurements in cold nuclear matter, essential (along with p-p studies) to a systematic study of QCD at high temperatures and densities in the search for the quark gluon plasma. Also accessible is a study of QCD in the… more

Distortion Correction for the Many Beam Fabry Perot Velocimeter

Description: Graphical curves and text tables are presented that map out time and space distortions for data obtained from film records of the Many Beam Fabry Perot Velocimeter. Effective distortion corrections extracted from these mappings can be applied to upcoming velocimetry experiments, but only with limited success over periods of a year or more into the future. A method of using three fiducials to provide fresh time and space distortion data on each film record is presented as a more reliable procedu… more

Dynamic Three-Dimensional Process Water Density Model for Ultrasim

Description: A temperature dependent D2O density model has been developed for the 3-D hydraulics module in the near real-time plant analysis code ULTRASIM. By replacing the constant density, ULTRASIM is improved in two ways. First, all 3-D hydraulic analyses performed are more physically realistic now that the temperature dependence of the D2O density is accounted for. Secondly, simple temperature driven process water transients can now be modeled and investigated, including natural circulation tests. This … more

Country-of-Origin Labeling for Foods: Current Law and Proposed Changes

Description: Federal law requires most imports, including many food items, to bear labels informing the “ultimate purchaser” of their country of origin. Various bills have been introduced to impose expanded country-of-origin labeling requirements on meats and on several other agricultural products. Such proposals have attracted attention for a number of reasons. One is that they are viewed (by some advocates) as a way to help U.S. producers dealing with low farm prices. Also, some perceive that food product… more

Farm Program Spending: What's Permitted Under the Uruguay Round Agreements

Description: This report discusses farm income and commodity price support proposals that might succeed the programs due to expire in 2002. A key question being asked of virtually every new proposal is how it will affect U.S. commitments under the 1994 Uruguay Round Agreement on Agriculture (URAA), which commitsthe United States to spend no more than $19.1 billion annually on domestic farm supports most likely to distort trade. The URAA spells out the rules for countries to determine whether their policies … more

Agriculture and Fast Track Trade Legislation

Description: The 107th Congress is expected to consider new "fast track" (or, Presidential trade promotion) authority, which could enable the Administration to submit trade agreements negotiated with foreign countries to Congress for consideration under expedited procedures. Many agricultural and food industry interests are among the export-oriented enterprises that support fast track authority, arguing that foreign trading partners will not seriously negotiate with an Administration that lacks it. However,… more

Micromachined VLSI 3D electronics. Final report for period September 1, 2000 - March 31, 2001

Description: The phase I program investigated the construction of electronic interconnections through the thickness of a silicon wafer. The novel aspects of the technology are that the length-to-width ratio of the channels is as high as 100:1, so that the minimum amount of real estate is used for contact area. Constructing a large array of these through-wafer interconnections will enable two circuit die to be coupled on opposite sides of a silicon circuit board providing high speed connection between the tw… more
