Electrical Submersible Pumps (ESPs) present higher efficiency, larger production rate, and can be operated in deeper wells than the other geothermal artificial lifting systems. Enhanced Geothermal Systems (EGS) applications recommend lifting 300 C geothermal water at 80kg/s flow rate in a maximum 10-5/8-inch diameter wellbore to improve the cost-effectiveness. In this paper, an advanced ESP design tool comprising a 1D theoretical model and a 3D CFD analysis has been developed to design ESPs for geothermal applications. Design of Experiments was also performed to optimize the geometry and performance. The designed mixed-flow type centrifugal impeller and diffuser exhibit high efficiency and head rise under simulated EGS conditions. The design tool has been validated by comparing the prediction to experimental data of an existing ESP product.

A series of developmental AFA alloys was selected for study based on: 25 Ni wt.% (alloys A-F), 20 wt% Ni (alloys G-H), and 12 Ni wt.% (alloys I-L). An emphasis in this work was placed on the lower alloy content direction for AFA alloys to reduce alloy raw material cost, rather than more highly alloyed and costly AFA alloys for higher temperature performance. Alloys A-D explored the effects of Al (3-4 wt.%) and C (0.05-0.2 wt.%) in the Fe-25Ni-14Cr-2Mn-2Mo-1W-1Nb wt.% base range; alloys E and F explored the effects of removing costly Mo and W additions in a Fe-25Ni-14Cr-4Al-2.5Nb-2Mn-0.2C base, alloys G and H examined Nb (1-2.5wt.%) and removal of Mo, W in a Fe-20Ni-14Cr-3Al-2Mn-0.2 C wt.% base; and alloys I-L examined effects of C (0.1-0.2 wt.%) and Mn (5-10 wt.%) on a low cost Fe-14Cr-12Ni-3Cu-2.5Al wt.% base (no Mo, W additions). Creep testing resulted in elemental trends that included the beneficial effect of higher carbon and lower niobium in 20-25%Ni AFA alloys and, the beneficial of lower Mn in 12%Ni AFA alloys. Corrosion tests in steam and sulfidation-oxidation environments showed, in general, these alloys were capable of a ten-fold improvement in performance when compared to conventional austenitic stainless steels. …

We have studied the effect of nanostructuring in Pt monolayer model electrocatalysts on a Rh(111) single-crystal substrate on the adsorption strength of chemisorbed species. In situ high energy resolution fluorescence detection X-ray absorption spectroscopy at the Pt L(3) edge reveals characteristic changes of the shape and intensity of the 'white-line' due to chemisorption of atomic hydrogen (H(ad)) at low potentials and oxygen-containing species (O/OH(ad)) at high potentials. On a uniform, two-dimensional Pt monolayer grown by Pt evaporation in ultrahigh vacuum, we observe a significant destabilization of both H(ad) and O/OH(ad) due to strain and ligand effects induced by the underlying Rh(111) substrate. When Pt is deposited via a wet-chemical route, by contrast, three-dimensional Pt islands are formed. In this case, strain and Rh ligand effects are balanced with higher local thickness of the Pt islands as well as higher defect density, shifting H and OH adsorption energies back toward pure Pt. Using density functional theory, we calculate O adsorption energies and corresponding local ORR activities for fcc 3-fold hollow sites with various local geometries that are present in the three-dimensional Pt islands.

Report on a flood protection plan for the Cottonwood Creek and Fish Creek Watersheds in the City of Arlington, Texas.

This report provides examples of recent Administration "combating violent extremism" (CVE) activity and examines some of the risks and challenges evident in the Strategic Implementation Plan for Empowering Local Partners to Prevent Violent Extremism in the United States' (SIP's) three objectives. The report also diagrams and briefly discusses the "future activities and efforts" outlined in the SIP for each of these three objectives.

In August 2011, the Obama Administration announced its counter-radicalization strategy. It is devised to address the forces that influence some people living in the United States to acquire and hold radical or extremist beliefs that may eventually compel them to commit terrorism. This is the first such strategy for the federal government, which calls this effort “combating violent extremism” (CVE). This report provides examples of recent Administration CVE activity and examines some of the risks and challenges evident in the SIP's three objectives. The report also diagrams and briefly discusses the “future activities and efforts” outlined in the SIP for each of these three objectives. A number of areas may call for oversight from Congress. These include the following: picking partners and establishing "rules of the road," intervention with at-risk individuals, identifying programs to assist grassroots CVE efforts, countering extremist ideas, the lack of a lead agency, and transparency.

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) has conducted about 2,800 security surveys and vulnerability assessments on critical infrastructure and key resources (CIKR). DHS directs its protective security advisors to contact owners and operators of high-priority CIKR to offer to conduct surveys and assessments. However, DHS is not positioned to track the extent to which these are performed at high-priority CIKR because of inconsistencies between the databases used to identify these assets and those used to identify surveys and assessments conducted. GAO compared the two databases and found that of the 2,195 security surveys and 655 vulnerability assessments conducted for fiscal years 2009 through 2011, 135 surveys and 44 assessments matched and another 106 surveys and 23 assessments were potential matches for high-priority facilities. GAO could not match additional high-priority facilities because of inconsistencies in the way data were recorded in the two databases, for example, assets with the same company name had different addresses or an asset at one address had different names. DHS officials acknowledged that the data did not match and have begun to take actions to improve the collection and organization of the …

This goal of this project was to develop cyber security audit and attack detection tools for industrial control systems (ICS). Digital Bond developed and released a tool named Bandolier that audits ICS components commonly used in the energy sector against an optimal security configuration. The Portaledge Project developed a capability for the PI Historian, the most widely used Historian in the energy sector, to aggregate security events and detect cyber attacks.

A letter report issued by the Government Accountability Office with an abstract that begins "At the departmental level, neither the Department of Defense (DOD) nor the individual military departments know the extent to which weapon system programs rely on long-term maintenance contracts. DOD policy requires DOD and the military departments to approve acquisition strategies and lifecycle sustainment plans, which include information on contractor support, but DOD officials reported that they do not collect information on the use of long-term contracts. DOD’s limited visibility over long-term maintenance contracts reflects broader DOD challenges with managing services acquisition. GAO’s past work has identified the need for DOD to obtain better data on its contracted services to enable it to make more strategic decisions. DOD is considering a number of policy- and data-related initiatives that could improve its knowledge of these contracts, but these efforts are in the early stages of development."

Projects under the NCHT have produced hydrogen from natural gas, …

In this report, we summarize the research in physics of elementary particles conducted by the Florida Tech DOE supported group at the CMS experiment at CERN, during the last 3-year cycle under this grant.

The focus of this research project was atoms with scattering lengths that are large compared to the range of their interactions and which therefore exhibit universal behavior at sufficiently low energies. Recent dramatic advances in cooling atoms and in manipulating their scattering lengths have made this phenomenon of practical importance for controlling ultracold atoms and molecules. This research project was aimed at developing a systematically improvable method for calculating few-body observables for atoms with large scattering lengths starting from the universal results as a first approximation. Significant progress towards this goal was made during the five years of the project.

The goal of this study was to validate the previously observed high biological kill performance of PAEROSOL, a semi-dry, micro-aerosol decontamination technology, against common HAI in a non-human subject trial within a hospital setting of Madigan Army Medical Center (MAMC) on Joint Base Lewis-McChord in Tacoma, Washington. In addition to validating the disinfecting efficacy of PAEROSOL, the objectives of the trial included a demonstration of PAEROSOL environmental safety, (i.e., impact to hospital interior materials and electronic equipment exposed during testing) and PAEROSOL parameters optimization for future deployment.

Correspondence issued by the Government Accountability Office with an abstract that begins "In summary, the Army and the Marine Corps have taken steps to determine the future usefulness of nonstandard equipment but have not finalized all of the decisions on whether to add such equipment to unit authorization documents. As of November 2011, the Army had reviewed 409 equipment systems through its Capabilities Development for Rapid Transition process, determining that about 11 percent of that equipment is useful for the future and about 37 percent is not needed and should be terminated. The Army has not made a final decision on the future need for the remaining 52 percent of the equipment, which it continues to sustain for current operations primarily through the use of overseas contingency operations funds. The Army has also taken some additional actions to review nonstandard equipment through other forums and reviews which have led to recommendations for some items to be retained for the future. Since 2008, the Marine Corps has reviewed 144 different requests for capabilities to fill gaps identified by commanders. Of these, the Marine Corps has determined that about 63 percent will continue to be needed in the future to meet enduring …

Governance models for the International Linear Collider Project are examined in the light of experience from similar international projects around the world. Recommendations for one path which could be followed to realize the ILC successfully are outlined. The International Linear Collider (ILC) is a unique endeavour in particle physics; fully international from the outset, it has no 'host laboratory' to provide infrastructure and support. The realization of this project therefore presents unique challenges, in scientific, technical and political arenas. This document outlines the main questions that need to be answered if the ILC is to become a reality. It describes the methodology used to harness the wisdom displayed and lessons learned from current and previous large international projects. From this basis, it suggests both general principles and outlines a specific model to realize the ILC. It recognizes that there is no unique model for such a laboratory and that there are often several solutions to a particular problem. Nevertheless it proposes concrete solutions that the authors believe are currently the best choices in order to stimulate discussion and catalyze proposals as to how to bring the ILC project to fruition. The ILC Laboratory would be set up by international treaty …

Correspondence issued by the Government Accountability Office with an abstract that begins "State has an extensive process designed to make the country reports on human rights as comprehensive, objective, and uniform as possible. This process includes annually issuing detailed instructions, consulting and assessing information from multiple sources, and collaboratively and iteratively drafting and reviewing the reports. State issues instructions for preparing the country reports each year, outlining a consistent structure and describing, for example, the topics that should be included in each subsection. The instructions also, among other things, indicate that the country reports should build on the previous year’s reports and specify guidelines for new and updated content. In addition, the instructions state that staff preparing the country reports are to use and assess multiple sources, including host governments, local and international human NGOs, labor unions, and host country media as well as classified information. State officials told us that they also obtain information from business leaders and industry groups, although there is no legal requirement to do so. In general, according to State officials, Foreign Service officers—often on their first or second tour of duty—prepare first drafts of the country reports with the assistance of other embassy personnel, …

Pacific Northwest National Laboratory evaluated juvenile salmonid passage and distribution at Lookout Point Dam (LOP) on the Middle Fork Willamette River for the U.S. Army Corps of Engineers, Portland District (USACE), to provide data to support decisions on long-term measures to enhance downstream passage at LOP and others dams in USACE's Willamette Valley Project. This study was conducted in response to the listing of Upper Willamette River Spring Chinook salmon (Oncorhynchus tshawytscha) and Upper Willamette River steelhead (O. mykiss) as threatened under the Endangered Species Act. We conducted a hydroacoustic evaluation of juvenile salmonid passage and distribution at LOP during February 2010 through January 2011. Findings from this 1 year of study should be applied carefully because annual variation can be expected due to variability in adult salmon escapement, egg-to-fry and fry-to-smolt survival rates, reservoir rearing and predation, dam operations, and weather. Fish passage rates for smolt-size fish (> {approx}90 mm and < 300 mm) were highest during December-January and lowest in mid-summer through early fall. Passage peaks were also evident in early spring, early summer, and late fall. During the entire study period, an estimated total of 142,463 fish {+-} 4,444 (95% confidence interval) smolt-size fish passed through turbine …

A letter report issued by the Government Accountability Office with an abstract that begins "During the 5-year period from fiscal year 2007 through 2011, the Department of Housing and Urban Development’s (HUD) Office of Inspector General (OIG) had budget and staffing resources that were consistent with other OIGs, and a monetary return for each budget dollar which exceeded the average return for Cabinet-level OIGs. During the 5-year period, the HUD OIG had total budgetary resources ranging from $121 million to $144 million, consistently ranking it fifth among all Cabinet-level OIGs. However, while the total budgetary resources for all Cabinet-level OIGs increased by about 45 percent over the 5-year period, the HUD OIG’s total budgetary resources increased by 19 percent. In terms of staffing, the HUD OIG’s full-time-equivalent staff (FTE) consistently ranked in the top four or five of the Cabinet-level OIGs. Also, the HUD OIG’s FTEs increased by about 13 percent during the 5-year period, as compared to about a 17 percent average increase for all Cabinet-level OIGs. During the same 5-year period, the HUD OIG reported an estimated average dollar return of about $13.62 for each HUD OIG total budgetary dollar received, while the 16 OIGs in the Cabinet-level …

A laser offers a unique set of opportunities for precise delivery of high quality coherent energy. This energy can be tailored to alter the properties of material allowing a very flexible adjustment of the interaction that can lead to melting, vaporization, or just surface modification. Nowadays laser systems can be found in nearly all branches of research and industry for numerous applications. Sufficient evidence exists in the literature to suggest that further advancements in the field of laser material processing will rely significantly on the development of new process schemes. As a result they can be applied in various applications starting from fundamental research on systems, materials and processes performed on a scientific and technical basis for the industrial needs. The interaction of intense laser radiation with solid surfaces has extensively been studied for many years, in part, for development of possible applications. In this thesis, I present several applications of laser processing of metals and polymers including polishing niobium surface, producing a superconducting phase niobium nitride and depositing thin films of niobium nitride and organic material (cyclic olefin copolymer). The treated materials were examined by scanning electron microscopy (SEM), electron probe microanalysis (EPMA), atomic force microscopy (AFM), high resolution …

The Reference Site (RS) study is part of the research, monitoring, and evaluation (RME) effort developed by the Action Agencies (Bonneville Power Administration [BPA], U.S. Army Corps of Engineers, Portland District [USACE], and U.S. Bureau of Reclamation) in response to Federal Columbia River Power System (FCRPS) Biological Opinions (BiOp). While the RS study was initiated in 2007, data have been collected at relatively undisturbed reference wetland sites in the LCRE by PNNL and collaborators since 2005. These data on habitat structural metrics were previously summarized to provide baseline characterization of 51 wetlands throughout the estuarine and tidal freshwater portions of the 235-km LCRE; however, further analysis of these data has been limited. Therefore, in 2011, we conducted additional analyses of existing field data previously collected for the Columbia Estuary Ecosystem Restoration Program (CEERP) - including data collected by PNNL and others - to help inform the multi-agency restoration planning and ecosystem management work underway in the LCRE.
