Project for laboratory study for removal of organic sulfur from coal. Quarterly technical progress report
The Gravimelt Process was extended to the desulfurization of ordinary mine-cleaned Kentucky No. 11 coal obtained from the Tennessee Valley Authority. Eight process runs were made resulting in reduction of the sulfur content from a starting 2.7 lbs S/10/sup 6/ Btu to a mean of 0.475 lbs S/10/sup 6/ Btu, (0.95 lbs SO/sub 2//10/sup 6/ Btu) for an average 82% sulfur reduction. The effect of utilization of molten sodium hydroxide alone vs molten mixed potassium and sodium hydroxide was investigated for this coal; sulfur reduction averaged 84% for the mixed melt and 78% for the use of sodium hydroxide alone. A double extraction with sodium hydroxide resulted in a reduction in total sulfur to 0.3 lbs S/10/sup 6/ Btu which is an 89% reduction. In a series of experiments, the melt was reused three times on fresh samples of coal, always giving the same amount of sulfur reduction. Extraction of the desulfurized Kentucky No. 11 coals with an additional dilute sulfuric acid wash reduced the ash content of the coal from 7.9% to a level of 0.3%, thus providing a solid hydrocarbon fuel similar in both ash and sulfur content to a medium grade fuel oil. Multiple experimentation on high …

Integrated dry NO sub x /SO sub 2 emissions control system
This project's goal is to demonstrate the removal up to 70% of the NO{sub x} and 70% of the SO{sub 2} emissions from coal fired utility boilers. It will establish an alternative emissions control technology integrating a combination of several processes, while minimizing capital expenditures and limiting waste production to dry solids that are handled with conventional ash removal equipment. These processes include low-NO{sub x} burners, NO{sub x} ports and urea injection for NO{sub x} control, sodium or calcium based sorbent injection for SO{sub 2} control, and flue gas humidification to enhance the reactivity of the SO{sub 2} control compound.

ASHRAE Standard 62-1989: Energy, Cost, and Program Implications.
ASHRAE Standard 62-1989 (Standard 62-89) Ventilation for Acceptable Indoor Air Quality'' is the new heating, ventilating, and air-conditioning (HVAC) industry consensus for ventilation air in commercial buildings. Bonneville Power Administration (Bonneville) references ASHRAE Standard 62-81 (the predecessor to Standard 62-89) in their current environmental documents for required ventilation rates. Through its use, it had become evident to Bonneville that Standard 62-81 needed interpretation. Now that the revised Standard (Standard 62-89) is available, its usefulness needs to be evaluated. Based on current information and public comment, the American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE) revised Standard 62-1981 to Standard 62-89. Bonneville's study estimated the energy and cost implications of ASHRAE Standard 62-89 using simulations based on DOE-2.1D, a computer simulation program which estimates building use hourly as a function of building characteristics and climatic location. Ten types of prototypical commercial buildings used by Bonneville for load forecasting purposes were examined: Large and Small Office, Large and Small Retail, Restaurant, Warehouse, Hospital, Hotel, School, and Grocery. These building characterizations are based on survey and energy metering data and represent average or typical construction and operation practices and mechanical system types. Prototypical building ventilation rates were varied in five steps to …

Microcomputer-based pellet trajectory guidance system for the Baseball II-T experiment
In the Baseball II-T experiment a pellet generation and injection system was employed to place frozen ammonia pellets at the focus of a laser beam. The original trajectory guidance system suffered a number of problems that limited its accuracy and complicated the operation of the system. These problems were related to variable charge-to-mass ratios, timing, pellet discrimination, and computer speed. The original system design was improved by changes to the sensing components, microcomputer, and trajectory guidance system.

Safety-analysis report for packaging (SARP) general-purpose heat-source module 750-Watt shipping container
The SARP includes discussions of structural integrity, thermal resistance, radiation shielding and radiological safety, nuclear criticality safety, and quality control. Extensive tests and evaluations were performed to show that the container will function effectively with respect to all required standards and when subjected to normal transportation conditions and the sequence of four hypothetical accident conditions (free drop, puncture, thermal, and water immersion). In addition, a steady state temperature profile and radiation profile were measured using two heat sources that very closely resemble the GPHS. This gave an excellent representation of the GPHS temperature and radiation profile. A nuclear criticality safety analysis determined that all safety requirements are met.

Medicare Fraud Prevention: CMS Has Implemented a Predictive Analytics System, but Needs to Define Measures to Determine Its Effectiveness
A letter report issued by the Government Accountability Office with an abstract that begins "The Centers for Medicare and Medicaid Services (CMS) implemented its Fraud Prevention System (FPS) in July 2011, as required by the Small Business Jobs Act, and the system is being used by CMS and its program integrity contractors who conduct investigations of potentially fraudulent claims. Specifically, FPS analyzes Medicare claims data using models of fraudulent behavior, which results in automatic alerts on specific claims and providers, which are then prioritized for program integrity analysts to review and investigate as appropriate. However, while the system draws on a host of existing Medicare data sources and has been integrated with existing systems that process claims, it has not yet been integrated with the agency's payment-processing system to allow for the prevention of payments until suspect claims can be determined to be valid. Program officials stated that this functionality has been delayed due to the time required to develop system requirements; they estimated that it will be implemented by January 2013 but had not yet developed reliable schedules for completing this activity."

USDA Graduate School: Revenue Reporting Needs to Be Improved
A letter report issued by the General Accounting Office with an abstract that begins "The U.S. Department of Agriculture's Graduate School provides extensive training opportunities to government employees and others. As a nonappropriated fund instrumentality, the Graduate School relies solely on income from the training it offers. During fiscal year 1999, the federal agencies GAO reviewed had 20 interagency agreements with the Graduate School totaling about $5.7 million. The agencies also had 531 contracts, totaling $29 million, with private companies for training and related services. The Graduate School's financial statements for fiscal year 1999 incorrectly identified the portion of revenue that was earned through interagency agreements. This misclassification occurred primarily because of the Graduate School's reporting policies."

Immigration Enforcement: ICE Could Improve Controls to Help Guide Alien Removal Decision Making
A letter report issued by the Government Accountability Office with an abstract that begins "Officers with U.S. Immigration and Customs Enforcement (ICE) within the Department of Homeland Security (DHS) investigate violations of immigration laws and identify aliens who are removable from the United States. ICE officers exercise discretion to achieve its operational goals of removing any aliens subject to removal while prioritizing those who pose a threat to national security or public safety and safeguarding aliens' rights in the removal process. The General Accountability Office (GAO) was asked to examine how ICE ensures that discretion is used in the most fair, reasoned, and efficient manner possible. GAO reviewed (1) when and how ICE officers and attorneys exercise discretion and what internal controls ICE has designed to (2) guide decision making and (3) oversee and monitor officers' decisions. To conduct this work, GAO reviewed ICE manuals, memorandums, and removal data, interviewed ICE officials, and visited 21 of 75 ICE field offices."

Elections: Statistical Analysis of Factors That Affected Uncounted Votes in the 2000 Presidential Election
A letter report issued by the General Accounting Office with an abstract that begins "Following the 2000 presidential election, concerns were raised about the election process, including the ability of some voting equipment to render a complete and accurate vote count. Furthermore, minorities and disadvantaged voters were seen as more likely to have their votes not counted because they may have used less reliable voting equipment than affluent white voters. GAO found that although the state in which counties are located had more of an effect on the number of uncounted presidential votes than did counties' demographic characteristics or voting equipment, there were statistically significant effects on uncounted presidential votes. State differences accounted for 26 percent of the total variation in uncounted presidential votes across counties. State differences may have included such factors as statewide voter education efforts, state standards for determining what is a valid vote, the use of straight party ballots, the number of candidates on the ballot, the use of provisional ballots, and the extent to which absentee or early voting occurred."

Clean Water Act: Longstanding Issues Impact EPA's and States' Enforcement Efforts
Testimony issued by the Government Accountability Office with an abstract that begins "Congress enacted the Clean Water Act to help reduce water pollution and improve the health of the nation's waterways. The Environmental Protection Agency (EPA) administers its enforcement responsibilities under the act through its Office of Enforcement and Compliance Assurance (OECA), as well as its 10 regional offices and the states. Over the last 9 years, GAO has undertaken a number of reviews of EPA's environmental enforcement activities, including for the Clean Water Act. For this testimony statement, GAO was asked to summarize the results of five prior reports on the effectiveness of EPA's enforcement program. Specifically, this statement includes information on the (1) factors that cause variations in enforcement activities and lead to inconsistencies across regions, (2) impact that inadequate resources and work force planning has had on enforcement, (3) efforts EPA has taken to improve priority planning, and (4) accuracy and transparency of measures of program effectiveness. GAO's prior recommendations have included the need for EPA to collect more complete and reliable data, develop improved guidance, and better performance measures. Although EPA has generally agreed with these recommendations, its implementation has been uneven. GAO is not making …
