Equilibrium Adsorption of Krypton and Xenon on Activated Carbon and Linde Molecular Sieves (open access)

Equilibrium Adsorption of Krypton and Xenon on Activated Carbon and Linde Molecular Sieves

Equilibrium krypton and xenon adsorption isotherms were obtained for four varieties of charcoal and for Linde Molecular Sieves Types 4A and 5A, generally at 0, 25, and 60°c. Such data are of interest in connection with design and evaluation of adsorbers for radioactive noble gas fission products. The isotherms were fitted, by linear regression analysis, to straight-line forms of the Freundlich and Langmuir equations. The Freundlich linear equation gave the better fit and the parameters of this equation are presented for each of the isotherms. Also presented are the constants for an equation representing the temperature dependence of arbitrary adsorption coefficients, the coefficients having been calculated from the Freundlich isotherm parameters. Some aspects of the applicability and accuracy of these results are discussed.

Discretionary Budget Authority by Subfunction: An Overview (open access)

Discretionary Budget Authority by Subfunction: An Overview

President Obama's FY2013 budget submission was released on February 13, 2012. This report provides a graphical overview of historical trends in discretionary budget authority (BA) from FY1976 through FY2011, enacted levels for FY2012 spending, and the levels consistent with the President's proposals for FY2013 through FY2017. Spending caps and budget enforcement mechanisms established in the Budget Control Act (BCA) of 2011 will probably strongly affect the FY2013 budget cycle. This report may provide a starting point for discussions about spending trends and federal priorities, but it does not attempt to explain spending patterns in each policy area.

Effect of Routing Upon Temperature of Cooling Stream (open access)

Effect of Routing Upon Temperature of Cooling Stream

With discussion under way concerning power production by chain reacting piles, it becomes pertinent to consider the ration of the temperature of the hottest spot in the pile to the average exit temperature of the cooling stream. This is important because the temperature of the hottest spot in the pile is one of the limiting factors in determining the maximum power at which a pile can be operated. However, the higher the temperature of the emerging cooling stream, the more efficient can be the thermal engine operated by it. Thus the ideal situation is to have the average exit temperature of the cooling stream as near as possible to the hottest temperature of the hottest spot in the pile.

The American Steel Industry: A Changing Profile

The U.S. steel industry has faced increasing difficulties since the late 1990s. More than 30 U.S. steel producers have gone into bankruptcy. While different companies and parts of the industry have been affected to different degrees, the two types of domestic producers of raw steel, integrated mills and minimills, have both supported restrictions on imports, which they say have undermined the ability of the U.S. industry to produce steel economically. This report reviews industry developments and the economic situation of the steel industry, including legacy cost aspects of its problems.

U.S.-Japan Economic Relations: Significance, Prospects, and Policy Options (open access)

U.S.-Japan Economic Relations: Significance, Prospects, and Policy Options

Japan and the United States are the two largest economic powers. Together they account for over 30% of world domestic product, for a significant portion of international trade in goods and services, and for a major portion of international investment. This economic clout makes the United States and Japan potentially powerful actors in the world economy. Economic conditions in the United States and Japan have a significant impact on the rest of the world. Furthermore, the U.S.-Japan bilateral economic relationship can influence economic conditions in other countries. More generally, other issues regarding U.S.-Japan economic relations may emerge on the agenda of the 112th Congress. U.S. and Japanese leaders have several options on how to manage their relationship, including stronger reliance on the World Trade Organization; special bilateral negotiating frameworks and agreements; or a free trade agreement.

EPA’s Proposed Policy on Wastewater Blending: Background and Issues (open access)

EPA’s Proposed Policy on Wastewater Blending: Background and Issues

In November 2003 the Environmental Protection Agency (EPA) proposed a policy regarding a type of wastewater treatment practice called blending. Some cities use blending to manage peak flows of water and waste into wastewater treatment plants during and after storms as a way to prevent conditions that otherwise result in raw sewage backups into homes and other buildings or overflows into nearby waters. This report provides background on blending, why and how it is practiced, EPA’s proposed policy, associated issues, and congressional interest in the topic.
