A first simulation study of the barrel-endcap transition region in a calorimeter of the scintillator tile design

Description: We have made a first study of the calorimetric response to 10 GeV/c charged pions in the transition region between barrel and endcap for the scintillator-tile design pursued at Argonne National Laboratory using the simulation program ANLSIM. For (very nearly) projective tower orientations in the barrel, the crack appears deep within a narrow angular range, causing a loss of the response in that region up to 40%. Pointing the towers onto the beam axis 35 cm or more away from the nominal-interaction point leads to a shortened depth of the barrel-endcap crack as seen by particles incident from the interaction region, cutting the maximum loss down by almost one half. The worsening of the resolution follows the same trend. Introduction of a solenoidal coil in front of the calorimeter causes an overall degradation of the response by an amount nearly comparable to the effect of the crack. Electrons of the same incident momentum are more strongly affected by the coil than pions but see only a much narrower region of degradation by the crack. 15 refs., 6 figs., 2 tabs.

Rock equation of state: a constitutive computer model

Description: A constitutive model for a rock equation of state was developed in HEMP and CEL-HEMP computer codes. The model includes the mechanical and thermal properties of soil, such as elasticity, pore closure, compaction, and vaporization. Three test problems were computed using the equation of state: ground motion following the LATIR event, impact vaporization of preheated plates, and surface motion produced from exploding a 3.7-kg(10-lb) charge at a depth of 6.5 m. Agreement between our computations from the model and actual measurements is remarkably close.

Group Purchasing Organizations: Services Provided to Customers and Initiatives Regarding Their Business Practices

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Health care providers rely on group purchasing organizations (GPO) to negotiate contracts with vendors of medical products. In 2002, questions were raised about GPOs engaging in potentially anticompetitive business practices such as collecting excessively high contract administrative fees. In 2003, GAO reported that selected GPOs had adopted or revised codes of conduct to respond to the questions about their business practices, but that it was too soon to evaluate the impact of the codes of conduct. GAO was asked to provide information on GPOs. In this report, GAO describes (1) the types of services that GPOs provide and how the GPOs fund these services, (2) initiatives that GPOs have implemented since 2002 to address the questions that had been raised about their business practices, and (3) the reported impact of the GPOs' codes of conduct and other initiatives. To do its work, GAO reviewed GPO documents and collected written responses to structured questions from the six largest GPOs based on their reported 2007 purchasing volume. GAO also conducted follow-up interviews with these six GPOs. GAO interviewed representatives from six GPO customers--hospitals--that varied in size, the GPOs with which they did business, and whether they had an ownership stake in a GPO. GAO also interviewed five medical product vendors of various sizes that do business with GPOs."

Very Light Jets: Several Factors Could Influence Their Effect on the National Airspace System

Description: A letter report issued by the Government Accountability Office with an abstract that begins "For several years, a number of aviation manufacturers have been designing and testing very light jets, a type of small jet aircraft equipped with advanced technologies and priced below other business jets. Aviation forecasters predict that thousands of very light jets will enter the National Airspace System (NAS) over the next two decades, contributing to the overall growth of the general aviation fleet. While some experts predict that very light jets will be used in ways that are similar to current general aviation aircraft, others predict that they will be used to expand the air taxi market to provide on-demand, point-to-point air transportation. In 2006, the Federal Aviation Administration (FAA) certified the first very light jets for flight. This report identifies (1) current very light jet forecasts and what factors could affect very light jet deliveries, (2) how increasing numbers of very light jets might affect the capacity and safety of the NAS, (3) how FAA is planning to accommodate the entry of very light jets into the NAS, and (4) how very light jets might affect FAA's costs and Airport and Airway Trust Fund revenues. To address these issues, GAO reviewed relevant documents and interviewed agency officials and aviation experts. GAO is not making recommendations in this report. The Department of Transportation provided technical clarifications, which were incorporated as appropriate."

Border Security: Consular Identification Cards Accepted within United States, but Consistent Federal Guidance Needed

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Several state and local government agencies and financial institutions accept consular identification (CID) cards, which are issued by foreign governments to their citizens living abroad. Mexico issued more than 2.2 million CID cards in 2002-2003 and Guatemala issued approximately 89,000 from mid-2002 to 2003. Critics of CID cards say their acceptance facilitates the unlawful stay within the United States of undocumented aliens and may provide opportunities for terrorists to remain undetected in this country. GAO examined (1) the purpose of a CID card and how Mexican and Guatemalan CID cards are being used in the United States, (2) steps Mexico and Guatemala have taken to verify the identities of CID card applicants and incorporate security features in CID cards now used in the United States, and (3) the positions and policies of federal agencies regarding CID cards."

State and Local Government Pension Plans: Governance Practices and Long-term Investment Strategies Have Evolved Gradually as Plans Take On Increased Investment Risk

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Recent market declines have significantly diminished the asset value of state and local pension plans. Reported unfunded liabilities for these plans are estimated in the hundreds of billions of dollars. As a result, in the long term, these governments may need to make significant fiscal adjustments such as modifying employee benefits, or increasing contributions to plans. They may also alter investment strategies to attempt to maximize returns by assuming increased risk. Consequently, GAO was asked to examine: (1) who makes investment decisions for state and local defined benefit pension plans and what guides their decision making; (2) how plans allocate their assets and manage their investments; and (3) practices that plans are using to meet a range of challenges in governance, investment, or funding. To address these objectives, GAO reviewed relevant literature, interviewed experts in pension and retirement systems, conducted a survey of state and local plans, and performed more detailed reviews of plans in seven states."

Federal Housing Administration: Agency Should Assess the Effects of Proposed Changes to the Manufactured Home Loan Program

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Pending legislation to the Federal Housing Administration's (FHA) Title I Manufactured Home Loan program would increase loan limits, insure each loan, incorporate stricter underwriting requirements, and set up-front premiums. GAO was asked to review (1) selected characteristics of manufactured housing and the demographics of the owners; (2) federal and state consumer protections for owners of manufactured homes; and (3) the potential benefits and costs of the proposed changes for borrowers and the federal government. In addressing these objectives, GAO analyzed select Census data; researched federal laws and laws in eight states; interviewed local, state, and federal officials; and analyzed various scenarios that might affect Title I program costs."

Strategic Petroleum Reserve: Available Oil Can Provide Significant Benefits, but Many Factors Should Influence Future Decisions about Fill, Use, and Expansion

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Congress authorized the Strategic Petroleum Reserve (SPR), operated by the Department of Energy (DOE), to release oil to the market during supply disruptions and protect the U.S. economy from damage. The reserve can store up to 727 million barrels of crude oil, and currently contains enough oil to offset 59 days of U.S. oil imports. GAO answered the following questions: (1) What factors do experts recommend be considered when filling and using the SPR? (2) To what extent can the SPR protect the U.S. economy from damage during oil supply disruptions? (3) Under what circumstances would an SPR larger than its current size be warranted? As part of this study, GAO developed oil supply disruption scenarios, used models to estimate potential economic harm, and convened 13 experts in conjunction with the National Academy of Sciences."

Nonprime Mortgages: Analysis of Loan Performance, Factors Associated with Defaults, and Data Sources

Description: A letter report issued by the Government Accountability Office with an abstract that begins "The surge in mortgage foreclosures that began in late 2006 and continues today was initially driven by deterioration in the performance of nonprime (subprime and Alt-A) loans. Nonprime mortgage originations increased dramatically from 2000 through 2006, rising from about 12 percent ($125 billion) of all mortgage originations to about 34 percent ($1 trillion). The nonprime market contracted sharply in mid-2007, partly in response to increasing defaults and foreclosures for these loans. This report (1) provides information on the performance of nonprime loans through December 31, 2009; (2) examines how loan and borrower characteristics and economic conditions influenced the likelihood of default (including foreclosure) of nonprime loans; and (3) describes the features and limitations of primary sources of data on nonprime loan performance and borrower characteristics, and discusses federal government efforts to improve the availability or use of such data. To do this work, GAO analyzed a proprietary database of securitized nonprime loans and Home Mortgage Disclosure Act data, and reviewed information on mortgage data sources maintained by private firms and the federal government."

Defense Management: Better Guidance Needed in Selecting Operating Methods for Name-Brand, Fast-Food Restaurants

Description: A letter report issued by the General Accounting Office with an abstract that begins "The military exchange services operate a wide range of retail activities, such as department stores, florist shops, barber and beauty shops, gas stations, and restaurants. Hamburger restaurants represent a major segment of the exchange services' name-brand, fast-food sales. The exchange services use either a direct or an indirect method to operate these restaurants. Under the direct method, the exchange service enters into a franchise agreement with a name-brand company to sell its product on a military installation. As the franchisee, the exchange service builds and operates the restaurant and directly employs and trains the personnel. In turn, the exchange service receives all of the revenues and profits and usually pays the company a licensing fee plus a percentage of the restaurant's sales. Under the indirect method, the exchange service contracts with a name-brand company that, in turn, builds the restaurant and either operates it as a company restaurant or provides a licensed operator. The company or its licensed operator hires, trains, and pays the restaurant personnel and usually pays annual fees and commissions to the exchange service on the basis of restaurant's sales. Under this agreement, the exchange service receives a percentage of the restaurant's annual sales; annual licensing fees; and, in some cases, a signing bonus or minimum guaranteed commissions. GAO's analysis of fiscal year 1998 and 1999 financial data from the Army and Air Force Exchange Service and the Navy Exchange Service Command showed that the indirect method of operating name-brand hamburger restaurants was more profitable than the direct method, regardless of the restaurants' sales volume, restaurant type (free-standing or part of a food court), or location. GAO's investment analysis projected that if new name-brand, hamburger restaurants were to be built, the indirect method …

Amtrak: Improved Management and Controls over Food and Beverage Service Needed

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Food and beverages have been served on board National Railroad Passenger Corporation (Amtrak) trains since Amtrak was created. Amtrak's 11 commissaries, located around the country, are responsible for receiving, warehousing and stocking food, beverages, and other items for Amtrak's on-board dining and cafe service. January 1999, Amtrak ran these commissaries with its own employees. Since then, Amtrak has contracted out the responsibility for the commissaries and for ordering and stocking all food, beverage, and related items under a contract that expires in September 2006. Gate Gourmet, the contractor, is also a supplier of food and beverages to several major airlines. During fiscal years 2002 through 2004, the period we focused on in our audit work, Amtrak paid Gate Gourmet between $59 million and $64 million a year in reimbursements and fees. Gate Gourmet personnel operate Amtrak-owned commissaries and order, receive, store, and stock trains with food, beverages, and other related items, such as table linens and napkins. Food and beverage supplies are charged to Amtrak employees who provide on-board food and beverage service and account for the food and beverages en route. When a train arrives at its final destination, all remaining stock items are returned to a commissary. Gate Gourmet charges Amtrak for the items used, as well as for labor, management, and other fees.Since Amtrak started operations in 1971, Amtrak has struggled financially and has depended on a federal subsidy of more than $1 billion a year since fiscal year 2003 to remain solvent. For fiscal years 2002 through 2004, Amtrak's food and beverage expenses were about $487 million--or only about 5 percent of the company's total expenditures. However, during that same time period, Amtrak's food and beverage service earned about $243 million in …

Trade Adjustment Assistance: Experiences of Six Trade-Impacted Communities

Description: A letter report issued by the General Accounting Office with an abstract that begins "This report reviews trade adjustment assistance and other assistance programs, such as the North American Free Trade Agreement Transitional Adjustment Assistance (NAFTA-TAA) program, to determine if they have helped distressed communities deal with the adverse impacts of trade. GAO conducted case studies in six such trade-impacted communities, all of which experienced major trade-related plant closures and layoffs in the mid- to late-1990s. Two communities lost a large percentage of local jobs in sudden plant closures and experienced economic crises. The other communities experienced rolling layoffs or a series of smaller plant closures that dislocated as many or more workers but did so gradually. Experiences in the communities GAO visited indicate that Temporary Adjustment Assistance (TAA) and NAFTA-TAA assistance to dislocated workers, although substantial, could be implemented more effectively. Program administrators and training providers in each community said that the programs have structural problems that impede effective service delivery. One factor that influenced the implementation of training benefits in many communities is that a significant percentage of dislocated workers needed to earn a high school equivalency degree or take remedial courses before they could even start a training program. Case study communities' experience with economic adjustment showed that the assistance available to them was limited and that there are no easy answers to community recovery, even when funds are available. These communities had relied on low-skilled manufacturing jobs, which are disappearing, and now face the difficult task of diversifying their economies while addressing fundamental human capital issues. These communities' experiences with efforts to assist dislocated workers and adjust to changing economic conditions offer several lessons. Program administrators and training providers said that bureaucratic rigidities in dislocated workers programs limited their flexibility in addressing dislocated workers' diverse training …

Nuclear Security: DOE Needs to Improve Control Over Classified Information

Description: A letter report issued by the General Accounting Office with an abstract that begins "The Department of Energy (DOE) maintains millions of classified documents containing highly sensitive nuclear weapons design and production information. Allegations that the Peoples Republic of China obtained nuclear warhead designs from an employee of DOE's Los Alamos National Laboratory, as well as the disappearance of two computer hard drives containing highly sensitive weapons information from that same laboratory, have raised concerns about how effectively DOE protects classified information, particularly the most sensitive classified information that is contained in vaults and computer systems. DOE's security program consists of many strategies for protecting and controlling classified information, such as controlling access to classified information through physical and administrative barriers and determining whether a person's work requires a "need to know" the information. DOE has recently increased protection for top-secret documents by revising its Classified Matter Protection and Control Manual, which provides detailed requirements for the protection and control of classified matter. This report reviews the (1) extent to which DOE's Sandia and Los Alamos National Laboratories have implemented DOE's established access controls and need-to-know requirements for classified vaults and computer systems containing the most sensitive classified information as well as the adequacy of these requirements and (2) steps DOE is taking to upgrade the protection of its classified information. GAO found that the Los Alamos and Sandia National Laboratories have implemented DOE's access controls and need-to-know requirements for both vaults and classified computer systems containing the most sensitive classified information. However, DOE's requirements for documenting need to know lack specificity, allowing laboratory managers wide variations in interpretation and implementation and. DOE has recently taken, and continues to take, steps to upgrade protection and control over its classified information, but additional steps are needed."

Theoretical considerations in solid bowl centrifugation

Description: A combination of literature survey and independent analysis determined three relationships for the prediction of the critical (or minimum recoverable) particle size in a solid bowl centrifuge. The relationships were derived based on three different theories of fluid behavior within the centrifuge; (1) laminar film flow (laminar film model), (2) plug flow (Sharples Model), and parabolic flow (modified Sharples Model). The critical particle size for the centrifuge used in Cs-PTA recovery in the CAW process predicted by the three relationships range from 0.19 to 0.34 ..mu..m (1 ..mu..m = 10/sup -6/m). The laminar film model gives the most conservative estimate of critical particle size (0.34 ..mu..m) and the resulting relationship is recommended for use to predict solid bowl centrifuge performance. Three correction factors are incorporated into the predictive equations to account for the effects of fluid turbulence near the centrifuge feed point, fluid lag and hindered settling. Of these factors, turbulence near the feed point (which is accounted for by using an effective centrifuge length) has the greatest impact, increasing the predicted critical particle size by 15%, while the combination of fluid lag and hindered settling factors increase the recoverable particle size by 4%. The overall effect of the correction factors is an approximately 20% decrease in centrifuge effectivity. The fraction of solids smaller than the critical size range has not been reliably determined for laboratory or plant prepared Cs-PTA. In addition, the density of Cs-PTA crystals is reported to vary from 3.2 to 12 grams per cubic centimeter.

Web Collection Plan Overview: Considerations for Project Curators

Description: This report is part of the Web-at-Risk project. The guidelines in this document are intended to assist the Web-at-Risk's project's curators in developing plans for the collections they will create using the project's Web Archiving Service (WAS). A web collection typically consists of a group of web-sites related by a common subject, theme, or event. Librarians will notice that some familiar concepts and practices from collection planning for print materials easily transfer to collection planning for web-published materials while some new concepts and unfamiliar practices are introduced. To effectively manage collections of web-published materials, it is good practice to either create new plans or modify existing collection plans to address these concepts and practices.
