Enhanced durability and reactivity for zinc ferrite desulfurization sorbent (open access)

Enhanced durability and reactivity for zinc ferrite desulfurization sorbent

AMAX Research Development Center (AMAX R D) has been investigating methods for improving the reactivity and durability of the zinc ferrite desulfurization sorbent. Zinc ferrite sorbents are intended for use in desulfurization of hog coal gas in integrated gasification combined cycle (IGCC) or molten carbonate fuel cell (MCFC) applications. The reactivity of the sorbent may be defined as its sulfur sorption capacity at the breakthrough point in a bench-scale fixed-bed reactor. The durability may be defined as the ability of the sorbent to maintain its reactivity and other important physical characteristics such as size, strength, and specific surface area during 10 cycles of sulfidation and regeneration. Two base case sorbents, spherical pellets and cylindrical extrudes used in related METC sponsored projects, are being used to provide a basis for the comparison of physical characteristics and chemical reactivity.

Upper limits on neutron bursts emitted from Ti pressurized D sub 2 gas cells (open access)

Upper limits on neutron bursts emitted from Ti pressurized D sub 2 gas cells

In a search for bursts of neutrons from Ti in pressurized D{sub 2} gas cells, no statistically significant deviations from the background were observed for events where five or more neutrons are detected over a ten day experiment, including 103 hours of counting with cells on, and 28 hours counting of various backgrounds. Up to four cells were used including some 60 grams of 662-Ti fillings in a pressurized cylinder with 40-60 atmosphere of D{sub 2} gas. Other Ti samples were used too. The samples were cooled to liquid nitrogen temperature and placed in front of the neutron detector while warming up to room temperature. Seven cooling cycles were used, for each sample. The neutron detector system included 12 liquid scintillator neutron detectors, arranged in a close packed geometry, with six detectors in the upper hemisphere and six in the lower hemisphere. A central detector placed 2 cm from the cells was used, in each hemisphere, as a scatterer for a time of flight coincidence measurement, yielding the total coincidence efficiency of {epsilon}=2{plus minus}1%. The system was also used in singles mode to allow for counting with large efficiency. A neutron event is characterized by measuring its pulse heights, pulse …

Credit Unions: Financial Condition Has Improved, but Opportunities Exist to Enhance Oversight and Share Insurance Management (open access)

Credit Unions: Financial Condition Has Improved, but Opportunities Exist to Enhance Oversight and Share Insurance Management

A letter report issued by the General Accounting Office with an abstract that begins "Recent legislative and regulatory changes have blurred some distinctions between credit unions and other depository institutions such as banks. The 1998 Credit Union Membership Access Act (CUMAA) allowed for an expansion of membership and mandated safety and soundness controls similar to those of other depository institutions. In light of these changes and the evolution of the credit union industry, GAO evaluated (1) the financial condition of the industry and the deposit (share) insurance fund, (2) the impact of CUMAA on the industry, and (3) how the National Credit Union Administration (NCUA) had changed its safety and soundness processes."

Military Personnel: Top Management Attention Is Needed to Address Long-standing Problems with Determining Medical and Physical Fitness of the Reserve Force (open access)

Military Personnel: Top Management Attention Is Needed to Address Long-standing Problems with Determining Medical and Physical Fitness of the Reserve Force

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense's (DOD) operations in time of war or national emergency depend on sizeable reserve force involvement and DOD expects future use of the reserve force to remain high. Operational readiness depends on healthy and fit personnel. Long-standing problems have been identified with reserve members not being in proper medical or physical condition. Drilling members in the reserve force by law are required to have a medical exam every 5 years and an annual certificate of their medical status. Also, DOD policies require an annual dental exam and an annual evaluation of physical fitness. Compliance with these routine requirements is the first step in determining who is fit for duty. Public Law 108-375 required GAO to study DOD's management of the health status of reserve members activated for Operations Enduring Freedom and Iraqi Freedom. GAO assessed DOD's (1) ability to determine reserve force compliance with routine exams, and (2) visibility over reserve members' health status after they are called to duty and the care, if any, provided to those deployed with preexisting conditions."

Biennial Budgeting: Three States' Experiences (open access)

Biennial Budgeting: Three States' Experiences

A letter report issued by the General Accounting Office with an abstract that begins "Members of Congress periodically have expressed interest in converting the federal budget process from an annual to a biennial cycle. Congress believes that the time spent on these activities has come at the expense of congressional oversight and authorization responsibilities. To better understand states' experiences with the biennial budget cycle, GAO studied three states: Arizona, Ohio, and Connecticut. GAO found that the states' reasons for changing their budget cycles varied. For example, Arizona adopted a biennial cycle to increase legislative oversight and reduce time spent on the budget. Connecticut adopted it as part of a fiscal reform effort. To execute a biennial budget successfully, the states' experiences suggest that the legislative and executive branches must agree on how the off-year budget process will work. Different approaches to managing the off-year budget have been developed by states, including establishing formal guidelines for off-year budget changes and relying on leadership control. Efforts to increase legislative oversight in the off-year by converting to a biennial budget process may be difficult. Ohio and Connecticut officials said they that have not increased legislative oversight in the off-year, and Arizona officials said …

Financial Management: Billions in Improper Payments Continue to Require Attention

A letter report issued by the General Accounting Office with an abstract that begins "As the steward of taxpayer dollars, the federal government is accountable for how its agencies and grantees spend funds. It is also responsible for safeguardingagainst improper payments, which include payments that should not have been madeor were made for incorrect amounts irrespective of whether the agency had effective controls in place. Reported estimates of improper payments total billions ofdollars annually. With billions of dollars at risk, agencies need to vigilantly safeguard those resources entrusted to them and assign a high priority to reducing fraud, waste, and abuse. In their fiscal year 1999 financial statement, 12federal agencies reported improper payments totalling $20.7 billion. A first step for some agencies will be to assess programs at risk and develope ways to identify, estimate, and report the nature and extent of improper payments annually. Without this fundamental knowledge, agencies will not be fully informed about the magnitude, trends, and types of payment errors occurring within their programs. Furthermore, most agencies will not be able to make informed cost-benefit decisions about strengthening their internal controls to minimize future improper payments or effectively develop goals and strategies to reduce them.

A letter report issued by the General Accounting Office with an abstract that begins "Public health experts have raised concerns about the ability of the nation's public health system to detect and respond to emerging infectious disease threats, such as pandemic influenza. Although vaccines are considered the first line of defense to prevent or reduce influenza-related illness and death, GAO found that they may be unavailable, in short supply, or ineffective for some portions of the population during the first wave of a pandemic. Federal and state influenza pandemic plans are in various stages of completion and do not completely or consistently address key issues surrounding the purchase, distribution, and administration of vaccines and antiviral drugs. Inconsistencies in state and federal policies could contribute to public confusion and weaken the effectiveness of the public health response."

Immigration Benefits: Additional Efforts Needed to Help Ensure Alien Files Are Located when Needed

A letter report issued by the Government Accountability Office with an abstract that begins "To document the interactions of aliens with the Department of Homeland Security's (DHS) United States Citizenship and Immigration Services (USCIS) and other government entities, USCIS creates alien files, or A-files. While deemed critical, especially in making citizenship decisions, A-files are sometimes missing during adjudications. In 2002, naturalization was granted to an alien whose A-file was missing and who was later found to be associated with a terrorist organization. GAO focused its review on (1) how often USCIS adjudicates naturalization applications without an A-file and why, (2) the effect that missing A-files can have on the adjudication process, and (3) steps taken to help mitigate the risk of missing A-files. To address these questions, GAO interviewed officials and staff from USCIS and reviewed relevant data, policies, and procedures related to processing naturalization applications and the automated file-tracking system DHS established to track the movement of A-files."

nu-TRLan User Guide Version 1.0: A High-Performance Software Package for Large-Scale Harmitian Eigenvalue Problems (open access)

nu-TRLan User Guide Version 1.0: A High-Performance Software Package for Large-Scale Harmitian Eigenvalue Problems

The original software package TRLan, [TRLan User Guide], page 24, implements the thick restart Lanczos method, [Wu and Simon 2001], page 24, for computing eigenvalues {lambda} and their corresponding eigenvectors v of a symmetric matrix A: Av = {lambda}v. Its effectiveness in computing the exterior eigenvalues of a large matrix has been demonstrated, [LBNL-42982], page 24. However, its performance strongly depends on the user-specified dimension of a projection subspace. If the dimension is too small, TRLan suffers from slow convergence. If it is too large, the computational and memory costs become expensive. Therefore, to balance the solution convergence and costs, users must select an appropriate subspace dimension for each eigenvalue problem at hand. To free users from this difficult task, nu-TRLan, [LNBL-1059E], page 23, adjusts the subspace dimension at every restart such that optimal performance in solving the eigenvalue problem is automatically obtained. This document provides a user guide to the nu-TRLan software package. The original TRLan software package was implemented in Fortran 90 to solve symmetric eigenvalue problems using static projection subspace dimensions. nu-TRLan was developed in C and extended to solve Hermitian eigenvalue problems. It can be invoked using either a static or an adaptive subspace dimension. In …
