    Use of steel and tantalum apparatus for molten Cd-Mg-Zn alloys

    Get PDF
    Steel and tantalum apparatus contains various ternary alloys of cadmium, zinc, and magnesium used in pyrochemical processes for the recovery of uranium-base reactor fuels. These materials exhibit good corrosion resistance at the high temperatures necessary for fuel separation in liquid metal-molten salt solvents

    Study and development of acoustic treatment for jet engine tailpipes

    A study and development program was accomplished to attenuate turbine noise generated in the JT3D turbofan engine. Analytical studies were used to design an acoustic liner for the tailpipe. Engine ground tests defined the tailpipe environmental factors and laboratory tests were used to support the analytical studies. Furnace-brazed, stainless steel, perforated sheet acoustic liners were designed, fabricated, installed, and ground tested in the tailpipe of a JT3D engine. Test results showed the turbine tones were suppressed below the level of the jet exhaust for most far field polar angles

    Sustainable agricultural residue removal for bioenergy: A spatially comprehensive US national assessment

    Get PDF
    This study provides a spatially comprehensive assessment of sustainable agricultural residue removal potential across the United States for bioenergy production. Earlier assessments determining the quantity of agricultural residue that could be sustainably removed for bioenergy production at the regional and national scale faced a number of computational limitations. These limitations included the number of environmental factors, the number of land management scenarios, and the spatial fidelity and spatial extent of the assessment. This study utilizes integrated multi-factor environmental process modeling and high fidelity land use datasets to perform the sustainable agricultural residue removal assessment. Soil type represents the base spatial unit for this study and is modeled using a national soil survey database at the 10–100 m scale. Current crop rotation practices are identified by processing land cover data available from the USDA National Agricultural Statistics Service Cropland Data Layer database. Land management and residue removal scenarios are identified for each unique crop rotation and crop management zone. Estimates of county averages and state totals of sustainably available agricultural residues are provided. The results of the assessment show that in 2011 over 150 million metric tons of agricultural residues could have been sustainably removed across the United States. Projecting crop yields and land management practices to 2030, the assessment determines that over 207 million metric tons of agricultural residues will be able to be sustainably removed for bioenergy production at that time. This biomass resource has the potential for producing over 68 billion liters of cellulosic biofuels

    Wage Discrimination and the Comparable Worth Theory in Perspective

    Get PDF
    Our article focuses primarily on one legal question: Does the wage discrimination theory, as sketched by Professor Blumrosen, fall within the remedial ambit of Title VII of the Civil Rights Act? Wage Discrimination\u27s factual contentions as to the existence and universality of wage discrimination deserve equally detailed analysis, but we leave that task to scholars of the pertinent disciplines, sociology and economics. We will deal with the factual contentions of Wage Discrimination only so far as necessary to challenge its central factual conclusion: that a demonstration of job separation should lead to a judicial inference of wage discrimination. This assertion is crucial to Professor Blumrosen\u27s argument because it is the basis for the proposal that incumbents of sex- or race-separated jobs are entitled, by virtue of their jobs alone, to higher wages. Because her social science evidence is unpersuasive and her legal analysis is unsound, we conclude that the courts and the Congress have been wise in refraining from attempts to impose the comparable worth theory on the American economy
