An Integrated Surface Engineering Technology Development for Improving Energy Efficiency of Engine Components
Frictional losses are inherent in most practical mechanical systems. The ability to control friction offers many opportunities to achieve energy conservation. Over the years, materials, lubricants, and surface modifications have been used to reduce friction in automotive and diesel engines. However, in recent years, progress in friction reduction technology has slowed because many of the inefficiencies have been eliminated. A new avenue for friction reduction is needed. Designing surfaces specifically for friction reduction with concomitant enhanced durability for various engine components has emerged recently as a viable opportunity due to advances in fabrication and surface finishing techniques. Recently, laser ablated dimples on surfaces have shown friction reduction properties and have been demonstrated successfully in conformal contacts such as seals where the speed is high and the load is low. The friction reduction mechanism in this regime appears to depend on the size, patterns, and density of dimples in the contact. This report describes modeling efforts in characterizing surface textures and understanding their mechanisms for enhanced lubrication under high contact pressure conditions. A literature survey is first presented on the development of descriptors for irregular surface features. This is followed by a study of the hydrodynamic effects of individual micro-wedge dimples …

Probabilistic Risk Based Decision Support for Oil and Gas Exploration and Production Facilities in Sensitive Ecosystems
This report describes work performed during the initial period of the project 'Probabilistic Risk Based Decision Support for Oil and Gas Exploration and Production Facilities in Sensitive Ecosystems.' The specific region that is within the scope of this study is the Fayetteville Shale Play. This is an unconventional, tight formation, natural gas play that currently has approximately 1.5 million acres under lease, primarily to Southwestern Energy Incorporated and Chesapeake Energy Incorporated. The currently active play encompasses a region from approximately Fort Smith, AR east to Little Rock, AR approximately 50 miles wide (from North to South). The initial estimates for this field put it almost on par with the Barnett Shale play in Texas. It is anticipated that thousands of wells will be drilled during the next several years; this will entail installation of massive support infrastructure of roads and pipelines, as well as drilling fluid disposal pits and infrastructure to handle millions of gallons of fracturing fluids. This project focuses on gas production in Arkansas as the test bed for application of proactive risk management decision support system for natural gas exploration and production. The activities covered in this report include meetings with representative stakeholders, development of initial content …

Vermont Biofuels Initiative: Local Production for Local Use to Supply a Portion of VermontâÂÂs Energy Needs
The Vermont Biofuels initiative (VBI) is the Vermont Sustainable Jobs FundâÂÂs (VSJF) biomass-to-biofuels market development program. Vermont is a small state with a large petroleum dependency for transportation (18th in per capita petroleum consumption) and home heating (55% of all households use petroleum for heating). The VBI marks the first strategic effort to reduce VermontâÂÂs dependency on petroleum through the development of homegrown alternatives. As such, it supports the four key priorities of the U.S. Department of EnergyâÂÂs Multi-year Biomass Plan: 1.) Dramatically reduce dependence on foreign oil; 2.) Promote the use of diverse, domestic and sustainable energy resources; 3.) Reduce carbon emissions from energy production and consumption; 4.) Establish a domestic bioindustry. In 2005 VSJF was awarded with a $496,000 Congressionally directed award from U.S. Senator Patrick Leahy. This award was administered through the U.S. Department of Energy (DE-FG36- 05GO85017, hereafter referred to as DOE FY05) with $396,000 to be used by VSJF for biodiesel development and $100,000 to be used by the Vermont Department of Public Service for methane biodigester projects. The intent and strategic focus of the VBI is similar to another DOE funded organizationâ the Biofuels Center of North CarolinaâÂÂin that it is a nonprofit driven, …

Clean Water Infrastructure: A Variety of Issues Need to Be Considered When Designing a Clean Water Trust Fund
A letter report issued by the Government Accountability Office with an abstract that begins "The Environmental Protection Agency (EPA) has estimated that a potential gap between future needs and current spending for wastewater infrastructure of $150 billion to $400 billion could occur over the next decade. A number of entities are involved in planning, financing, building, and operating this infrastructure. Some of these stakeholders have suggested a variety of approaches to bridge this potential gap. One such proposal is to establish a clean water trust fund. In this context, GAO was asked to (1) obtain stakeholders' views on the issues that would need to be addressed in designing and establishing a clean water trust fund and (2) identify and describe potential options that could generate about $10 billion in revenue to support a clean water trust fund. In conducting this review, GAO administered a questionnaire to 28 national organizations representing the wastewater and drinking water industries, state and local governments, engineers, and environmental groups and received 22 responses; reviewed proposals and industry papers; interviewed federal, state, local, and industry officials; and used the most current data available to estimate the revenue that could potentially be raised by various taxes on …

Federal Contracting: Guidance on Award Fees Has Led to Better Practices but Is Not Consistently Applied
A letter report issued by the Government Accountability Office with an abstract that begins "In prior work, GAO found that contractors were paid billions of dollars in award fees regardless of acquisition outcomes. In December 2007, the Office of Management and Budget (OMB) issued guidance aimed at improving the use of award fee contracts. GAO was asked to (1) identify agencies' actions to revise or develop award fee policies and guidance to reflect OMB guidance, (2) assess the consistency of current practices with the new guidance, and (3) determine the extent agencies are collecting, analyzing, and sharing information on award fees. GAO reviewed the Departments of defense (DOD), Energy (DOE), Health and Human Services (HHS), and Homeland Security (DHS) and the National Aeronautics and Space Administration (NASA)--agencies that constituted over 95 percent of the dollars spent on award fee contracts in fiscal year 2008."

International Food Assistance: Local and Regional Procurement Can Enhance the Efficiency of U.S. Food Aid, but Challenges May Constrain Its Implementation
A letter report issued by the Government Accountability Office with an abstract that begins "While the U.S. approach of providing in-kind food aid has assisted millions of hungry people for more than 50 years, in 2007 GAO reported limitations to its efficiency and effectiveness. To improve U.S. food assistance, Congress has authorized some funding for local and regional procurement (LRP)--donors' purchase of food aid in countries affected by food crises or in a country within the same region. Through analysis of agency documents, interviews with agency officials, experts, and practitioners, and fieldwork in four African countries, this requested report examines (1) LRP's impact on the efficiency of food aid delivery; (2) its impact on economies where food is procured; and (3) U.S. legal requirements that could affect agencies' use of LRP."

ITER Generic Diagnostic Upper Port Plug Nuclear Heating and Personnel Dose Rate Assesment Neutronics Analysis using the ATTILA Discrete Ordinates Code
Neutronics analysis to find nuclear heating rates and personnel dose rates were conducted in support of the integration of diagnostics in to the ITER Upper Port Plugs. Simplified shielding models of the Visible-Infrared diagnostic and of the ECH heating system were incorporated in to the ITER global CAD model. Results for these systems are representative of typical designs with maximum shielding and a small aperture (Vis-IR) and minimal shielding with a large aperture (ECH). The neutronics discrete-ordinates code ATTILA® and SEVERIAN® (the ATTILA parallel processing version) was used. Material properties and the 500 MW D-T volume source were taken from the ITER “Brand Model” MCNP benchmark model. A biased quadrature set equivelant to Sn=32 and a scattering degree of Pn=3 were used along with a 46-neutron and 21-gamma FENDL energy subgrouping. Total nuclear heating (neutron plug gamma heating) in the upper port plugs ranged between 380 and 350 kW for the Vis-IR and ECH cases. The ECH or Large Aperture model exhibited lower total heating but much higher peak volumetric heating on the upper port plug structure. Personnel dose rates are calculated in a three step process involving a neutron-only transport calculation, the generation of activation volume sources at pre-defined …
