Reaction kinetic measurements on the hydrochlorination of SiCl/sub 4/ and mg silicon metal in the presence of a copper catalyst were last reported as a function of reaction temperature, reactor pressure and H/sub 2//SiCl/sub 4/ ratio, 3 SiCl/sub 4/ + 2 H/sub 2/ + Si ..-->.. 4 SiHCl/sub 3/. The same reaction was repeated at a lower catalyst loading of 2 wt%. In the presence of 2 wt% cuprous chloride (based on silicon metal), the hydrochlorination reaction rate is doubled to give about the same performance as those obtained at a higher copper catalyst loading. The effect of particle size distribution of the mg silicon metal on the hydrochlorination reaction rate was studied. Reaction kinetic measurements were made on 150 x 400 mesh Si and on 32 x 65 mesh Si in addition to the standard 65 x 150 mesh Si used in previous studies. Results of these experiments show that the reaction rate is essentially independent of the silicon metal particle size. Thus, the reaction occuring on the Si metal surface is the rate-determining step. Mass transfer via diffusion of reactants and product is not rate-limiting. A plausible mechanism of the hydrochlorination reaction is discussed.

This report on the Sensitivity of Mission Analysis and Trade-off Studies provides an analysis of the sensitivity of the results of previous mission analysis and performance specification studies to the possible variations of the values of significant parameters as projected to the year 1985. These parameters include vehicle usage by purpose, driving cycles, trip lengths, ownership projections, and life-cycle costs. Tabulated data are included from calculations with variations in these parameters. (LCL)

Correspondence issued by the General Accounting Office with an abstract that begins "On June 4, 2003, GAO testified before the Senate Committee on Governmental Affairs at a hearing entitled "Transforming the Department of Defense Personnel System: Finding the Right Approach." This letter responds to a request that we provide answers to posthearing questions from Senator George V. Voinovich and Senator Thomas R. Carper concerning the proposed Department of Defense (DOD) Human Capital Reform."

A letter report issued by the Government Accountability Office with an abstract that begins "According to the Department of Health and Human Services (HHS), schemes to defraud the Medicare program have grown more elaborate in recent years. In particular, HHS has acknowledged Centers for Medicare & Medicaid Service's (CMS) oversight of suppliers of durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS) is inadequate to prevent fraud and abuse. Specifically, weaknesses in the DMEPOS enrollment and inspection process have allowed sham companies to fraudulently bill Medicare for unnecessary or nonexistent supplies. From April 2006 through March 2007, CMS estimated that Medicare improperly paid $1 billion for DMEPOS supplies--in part due to fraud by suppliers. Due to the committee's concern about vulnerabilities in the enrollment process, GAO used publicly available guidance to attempt to create DMEPOS suppliers, obtain Medicare billing numbers, and complete electronic test billing. GAO also reported on closed cases provided by the HHS Inspector General (IG) to illustrate the techniques used by criminals to fraudulently bill Medicare. On June 18, 2008, we briefed CMS representatives on the results of our investigation. In response, they acknowledged that our covert tests illustrate gaps in oversight that still require improvement and stated …

A letter report issued by the Government Accountability Office with an abstract that begins "The Biggert-Waters Flood Insurance Reform Act of 2012 (Biggert-Waters Act) immediately eliminated subsidies for about 438,000 National Flood Insurance Program (NFIP) policies, but subsidies on an estimated 715,000 policies across the nation remain. Depending on factors such as policyholder behavior, the number of subsidized policies will continue to decline over time. For example, as properties are sold and the Federal Emergency Management Agency (FEMA) resolves data limitations and defines key terms, more subsidies will be eliminated. GAO analysis found that remaining subsidized policies would cover properties in every state and territory where NFIP operates, with the highest numbers in Florida, Louisiana, and California. In comparing remaining subsidized and nonsubsidized policies GAO found varying characteristics. For example, counties with the highest and lower home values had a larger percentage of subsidized versus nonsubsidized policies."

Correspondence issued by the General Accounting Office with an abstract that begins "This report provides information on hourly fees paid by the federal government to private attorneys for legal services in fiscal years 1999, 2000, and 2001. Relevant legal services include federal employee defense, litigative consultation, intellectual property consultation, and asset forfeiture-related services. For these types of services, GAO obtained information on hourly fees paid to private attorneys by the Department of Justice, the Administrative Office of the United States Courts, the National Aeronautics and Space Administration, and the Department of Veterans Affairs. GAO found that the hourly fees paid to private attorneys ranged from $125 to $357, depending on the agency and the type of legal service."

A letter report issued by the Government Accountability Office with an abstract that begins "From 2003 through 2011, the U.S. Department of Agriculture (USDA) made more than $46 billion in direct payments to farmers and other producers. These producers planted varying percentages of acres that qualified for payments based on their historical planting yields and designated payment rates (qualifying acres). Cumulatively, USDA paid $10.6 billion—almost one-fourth of total direct payments made from 2003 through 2011—to producers who did not, in a given year, grow the crop associated with their qualifying acres, which they are allowed to do. About 2,300 farms (0.15 percent of farms receiving direct payments) reported all their land as “fallow,” and producers did not plant any crops on this land for each year for the last 5 years, from 2007 through 2011; in 2011, these producers received almost $3 million in direct payments."

Correspondence issued by the General Accounting Office with an abstract that begins "The National Nuclear Security Administration (NNSA) spends $5.5 billion a year to maintain the safety and reliability of the nation's nuclear weapons stockpile through the Stockpile Stewardship Program. Because the United States is no longer designing and building new nuclear weapons, extending the life of each of the nine weapon types in the current stockpile is a key component of this program. However, the criteria used by NNSA for determining when its reporting should begin may prevent Congress from receiving complete information on life extension costs. The current Nuclear Weapon Acquisition Reports (NWAR) are less detailed and comprehensive than the Department of Defense's Selected Acquisition Reports. Finally, the cost data in the NWARs exclude significant costs that are necessary to successfully complete the life-extension efforts."

A letter report issued by the Government Accountability Office with an abstract that begins "The number of Regulation A offerings filed and qualified (that is, cleared) by the Securities and Exchange Commission (SEC) has declined significantly after peaking in fiscal years 1997 and 1998, respectively. In particular, offerings filed since 1997 decreased from 116 in 1997 to 19 in 2011. Similarly, the number of qualified offerings dropped from 57 in 1998 to 1 in 2011. Securities attorneys GAO interviewed suggested that the decrease in filings after 1997 could be attributed to a number of factors, including the increased attractiveness of Regulation D. The National Securities Markets Improvement Act of 1996 preempted state registration requirements for other categories of securities including certain Regulation D offerings, which are also exempt from SEC registration. In contrast, Regulation A offerings are generally subject to state securities laws and must go through a federal filing and review process. In recent years, businesses have used Regulation D and registered public offerings to a greater extent than Regulation A."

A letter report issued by the Government Accountability Office with an abstract that begins "Since the implementation of the auditor attestation requirement of the Sarbanes-Oxley Act of 2002 (Sarbanes-Oxley Act), companies exempt from the requirement have had more financial restatements (a company's revision of publicly reported financial information) than nonexempt companies, and the percentage of exempt companies restating generally has exceeded that of nonexempt companies. Exempt and nonexempt companies restated their financial statements for similar reasons (e.g., revenue recognition and expenses), and the majority of these restatements produced a negative effect on the companies' financial statements."

A letter report issued by the General Accounting Office with an abstract that begins "This report reviews information system general controls over the financial systems maintained by the Department of the Interior at its National Business Center (NBC) in Denver, Colorado. GAO found that although the Denver center has made progress in correcting previously cited computer security weaknesses, additional weaknesses affect the Denver center's information system control environment. These weaknesses affect the center's ability to prevent and detect unauthorized changes to financial information, control electronic access to sensitive personnel information, and restrict physical access to sensitive computing areas. The Denver center did not adequately limit access granted to authorized users, control all aspects of the system software controls, or secure access to its network. Also, the Denver center had not fully established a comprehensive program to routinely monitor access to its computer facilities and data and to identify and investigate unusual or suspicious access patterns that could indicate unauthorized access. The primary reason for these weaknesses was that the Denver center had not yet fully developed and implemented a comprehensive entitywide program to manage computer security."

Testimony issued by the General Accounting Office with an abstract that begins "The challenges posed by homeland security exceed the capacity and authority of any one level of government. Protecting the nation against these threats calls for a truly integrated approach, bringing together the resources of all levels of government. The proposed Department of Homeland Security will have a central role in efforts to enhance homeland security. The proposed consolidation of homeland security programs has the potential to reduce fragmentation, improve coordination, and clarify roles and responsibilities. However, formation of a department should not be considered a replacement for the timely issuance of a national homeland security strategy to guide implementation of the complex mission of the department. Appropriate roles and responsibilities within and between the government and private sector need to be clarified. New threats are prompting a reassessment and shifting of long-standing roles and responsibilities, but these shifts are being considered on a piecemeal and ad hoc basis without benefit of an overarching framework and criteria. A national strategy could provide guidance by more systematically identifying the unique capacities and resources at each level of government to enhance homeland security and by providing increased accountability within the intergovernmental …

A letter report issued by the General Accounting Office with an abstract that begins "The 1998 Workforce Investment Act (WIA) required states to provide most federally funded employment-related services through one-stop centers. Two years earlier, welfare reform legislation created the Temporary Assistance for Needy Families (TANF) block grant which provided flexibility to states to focus on helping needy adults with children find and maintain employment. Nearly all states reported some coordination of their TANF and WIA services at the state or local level, and the use of some of these coordination methods increased between 2000 and 2001. Historical relationships, geographic considerations, adequacy of facilities, and different perspectives on how best to serve TANF clients influenced how states and localities choose to coordinate services with one-stop centers. Several challenges, including program differences between TANF and WIA and different information systems used by welfare and workforce agencies, inhibit state and local coordination efforts. Though some states and localities have found creative ways to work around these issues, the differences remain barriers to coordination for many others."

A letter report issued by the General Accounting Office with an abstract that begins "In recent years, the Washington Metropolitan Area Transit Authority's (WMATA) public transit system has experienced problems with the safety and reliability of its transit services, including equipment breakdowns, delays in scheduled service, unprecedented crowding on trains, and some accidents and tunnel fires. At the same time, WMATA's ridership is at an all time high and WMATA managers expect the number of passengers to double during the next 25 years. This report reviews (1) the challenges WMATA faces in operating and maintaining its Metrorail system; (2) efforts WMATA has made to establish and monitor safety and security within its transit system; and (3) the extent to which WMATA follows established best practices in planning, selecting, and budgeting for its capital investments. GAO found that WMATA is addressing significant challenges brought about by the agency's aging equipment and infrastructure and its ever-increasing ridership. WMATA has established programs to identify, evaluate, and minimize safety and security risks throughout its rail and bus systems. WMATA has also adopted several best capital practices used by leading public and private sector organizations, but it could benefit by establishing a more formal, disciplined …

Other written product issued by the General Accounting Office with an abstract that begins "The Joint Financial Management Improvement Program Non-Income Tax Revenue System Requirements documents is intended to provide a common set of non-income tax revenue financial information requirements with which each agency's integrated financial management system must be consistent. This document delineates those interface requirements between non-income tax revenue and other systems that are critical to the performance of both functions. These requirements are intended to be available to all users who rely on the information to carry out their responsibilities. This document does not address system requirements associated solely with the non-income tax revenue process."

A letter report issued by the General Accounting Office with an abstract that begins "To ensure the completeness and accuracy of the 2000 census data, Bureau of the Census analysts were to identify, investigate, and document suspected data discrepancies or issues to clear census data files and products for subsequent processing or public release. They were to determine whether and how to correct the data by weighing quality improvements against time and budget constraints. Because the bureau lacked sufficient staff to conduct a full count review on its own, it contracted out some of the work to members of the Federal-State Cooperative Program for Population Estimates (FSCPE). FSCPE documented 1,402 data issues, 29 percent of the 4,809 issues identified by both FSCPE and bureau analysts during the full count review. Of the 4,809 issues, 1,599 dealt with "group quarters," where counts for prisons, nursing homes, dormitories, and other group living facilities differed from what analysts expected. Of the 1,599 group quarters issues, FSCPE identified 567. Discrepancies relating to housing unit counts, population data, and demographic characteristics accounted for 1,150 issues, 375 of which were identified by FSCPE. Overall, of the 4,809 issues identified during review, 4,267 were not subjected to …
