    The importance and need for full compliant implementation of NIMS nationwide was clearly demonstrated during the Hurricane Katrina event, which was clearly expressed in Secretary Chertoff's October 4, 2005 letter addressed to the State's governors. It states, ''Hurricane Katrina was a stark reminder of how critical it is for our nation to approach incident management in a coordinated, consistent, and efficient manner. We must be able to come together, at all levels of government, to prevent, prepare for, respond to, and recover from any emergency or disaster. Our operations must be seamless and based on common incident management doctrine, because the challenges we face as a nation are far greater than capabilities of any one jurisdiction.'' The NIMS is a system/architecture for organizing response on a ''national'' level. It incorporations ICS as a main component of that structure (i.e., it institutionalizes ICS in NIMS). In a paper published on the NIMS Website, the following statements were made: ''NIMS represents a core set of doctrine, principles, terminology, and organizational processes to enable effective, efficient and collaborative incident management at all levels. To provide the framework for interoperability and compatibility, the NIMS is based on a balance between flexibility and standardization.'' Thus the NIC is challenged with the need to adopt quality SDO generated standards to support NIMS compliance, but in doing so maintain the flexibility necessary so that response operations can be tailored for the specific jurisdictional and geographical needs across the nation. In support of this large and complex challenge facing the NIC, the Pacific Northwest National Laboratory (PNNL) was asked to provide technical support to the NIC, through their DHS Science and Technology ? Standards Portfolio Contract, to help identify, review, and develop key standards for NIMS compliance. Upon examining the challenge, the following general process appears to be a

    This paper describes a comparison between PTB and NIM in the field of absolute spectral-band radiometry and thermodynamic temperature measurement. For the comparison a NIM made interference filter radiometer with a centre wavelength of 633 nm was taken to PTB. The filter radiometer was calibrated at NIM and PTB with respect to spectral irradiance responsivity. For the integral value in the band-pass range an agreement of 0.1% was observed in both calibrations. In a next step, the 633 nm filter radiometer was used to measure the temperature of a high-temperature blackbody in comparison to an 800 nm filter radiometer of PTB in the temperature range between 1400 K and 2750 K. The thermodynamic temperature measured by the two filter radiometers agreed to within 0.2 K to 0.5 K with an estimated measurement uncertainty ranging between 0.1 K and 0.4 K (k=1)

  13. Improving Control System Security through the Evaluation of Current Trends in Computer Security Research

    2005-03-01

    At present, control system security efforts are primarily technical and reactive in nature. What has been overlooked is the need for proactive efforts, focused on the IT security research community from which new threats might emerge. Evaluating cutting edge IT security research and how it is evolving can provide defenders with valuable information regarding what new threats and tools they can anticipate in the future. Only known attack methodologies can be blocked, and there is a gap between what is known to the general security community and what is being done by cutting edge researchers --both those trying to protect systems and those trying to compromise them. The best security researchers communicate with others in their field; they know what cutting edge research is being done; what software can be penetrated via this research; and what new attack techniques and methodologies are being circulated in the black hat community. Standardization of control system applications, operating systems, and networking protocols is occurring at a rapid rate, following a path similar to the standardization of modern IT networks. Many attack methodologies used on IT systems can be ported over to the control system environment with little difficulty. It is extremely important to take advantage of the lag time between new research, its use on traditional IT networks, and the time it takes to port the research over for use on a control system network. Analyzing nascent trends in IT security and determining their applicability to control system networks provides significant information regarding defense mechanisms needed to secure critical infrastructure more effectively. This work provides the critical infrastructure community with a better understanding of how new attacks might be launched, what layers of defense will be needed to deter them, how the attacks could be detected, and how their impact could be limited.

    A quantum-voltage-calibrated Johnson-noise thermometer was developed at NIM, which measures the Boltzmann constant k by comparing the thermal noise across a 100 ? sense resistor at the temperature of the triple point of water with the pseudo-random frequency-comb voltage waveform synthesized with a bipolar-pulse-driven quantum-voltage-noise source. A measurement with integration period of 10 hours and bandwidth of 640 kHz resulted in a relative offset of 0.5×10{sup ?6} from the current CODATA value of k, and a type A relative standard uncertainty of 23×10{sup ?6}. Benefiting from closely matched noise powers and transmission-line impedances and small nonlinearities in the cross-correlation electronics, the derived k shows self-consistent values and standard uncertainties for different measurement bandwidths.

In his presentation, Professor Tarascon recounted European basic research activates in electrical energy storage. The 2011 EFRC Summit and Forum brought together the EFRC community and science and policy leaders from universities, national laboratories, industry and government to discuss "Science for our Nation's Energy Future." In August 2009, the Office of Science established 46 Energy Frontier Research Centers. The EFRCs are collaborative research efforts intended to accelerate high-risk, high-reward fundamental research, the scientific basis for transformative energy technologies of the future. These Centers involve universities, national laboratories, nonprofit organizations, and for-profit firms, singly or in partnerships, selected by scientific peer review. They are funded at $2 to $5 million per year for a total planned DOE commitment of $777 million over the initial five-year award period, pending Congressional appropriations. These integrated, multi-investigator Centers are conducting fundamental research focusing on one or more of several ?grand challenges? and use-inspired ?basic research needs? recently identified in major strategic planning efforts by the scientific community. The purpose of the EFRCs is to integrate the talents and expertise of leading scientists in a setting designed to accelerate research that transforms the future of energy and the environment.

    The Two Stage Coal Liquefaction process became operational at Wilsonville in May 1981, with the inclusion of an H-OIL ebullated-bed catalytic reactor. The two stage process was initially operated in a nonintegrated mode and has recently been reconfigurated to fully integrate the thermal and the catalytic stages. This report focuses on catalyst activity trends observed in both modes of operation. A literature review of relevant catalyst screening studies in bench-scale and PDU units is presented. Existing kinetic and deactivation models were used to analyze process data over an extensive data base. Based on the analysis, three separate, application studies have been conducted. The first study seeks to elucidate the dependence of catalyst deactivation rate on type of coal feedstock used. A second study focuses on the significance of catalyst type and integration mode on SRC hydrotreatment. The third study presents characteristic deactivation trends observed in integrated operation with different first-stage thermal severities. In-depth analytical work was conducted at different research laboratories on aged catalyst samples from Run 242. Model hydrogenation and denitrogenation activity trends are compared with process activity trends and with changes observed in catalyst porosimetric properties. The accumulation of metals and coke deposits with increasing catalyst age, as well as their distribution across a pellet cross-section, are discussed. The effect of catalyst age and reactor temperature on the chemical composition of flashed bottoms product is addressed. Results from regenerating spent catalysts are also presented. 35 references, 31 figures, 18 tables.

    2007-04-01

    Homeland Security Presidential Directive HSPD-5 requires all federal departments and agencies to adopt a National Incident Management System (NIMS)/Incident Command System (ICS) and use it in their individual domestic incident management and emergency prevention, preparedness, response, recovery, and mitigation programs and activities, as well as in support of those actions taken to assist state and local entities. This system provides a consistent nationwide template to enable federal, state, local, and tribal governments, private-sector, and nongovernmental organizations to work together effectively and efficiently to prepare for, prevent, respond to, and recover from domestic incidents, regardless of cause, size, or complexity, including acts of catastrophic terrorism. This document identifies the operational concepts of the Federal Radiological Monitoring and Assessment Center's (FRMAC) implementation of the NIMS/ICS response structure under the National Response Plan (NRP). The construct identified here defines the basic response template to be tailored to the incident-specific response requirements. FRMAC's mission to facilitate interagency environmental data management, monitoring, sampling, analysis, and assessment and link this information to the planning and decision staff clearly places the FRMAC in the Planning Section. FRMAC is not a mitigating resource for radiological contamination but is present to conduct radiological impact assessment for public dose avoidance. Field monitoring is a fact-finding mission to support this effort directly. Decisions based on the assessed data will drive public protection and operational requirements. This organizational structure under NIMS is focused by the mission responsibilities and interface requirements following the premise to provide emergency responders with a flexible yet standardized structure for incident response activities. The coordination responsibilities outlined in the NRP are based on the NIMS

    Early approaches to surgical implantation of electronic tags in fish were often through trial and error, however, in recent years there has been an interest in using scientific research to identify techniques and procedures that improve the outcome of surgical procedures and determine the effects of tagging on individuals. Here we summarize the trends in 108 peer-reviewed electronic tagging effect studies focused on intracoleomic implantation to determine opportunities for future research. To date, almost all of the studies have been conducted in freshwater, typically in laboratory environments, and have focused on biotelemetry devices. The majority of studies have focused on salmonids, cyprinids, ictalurids and centrarchids, with a regional bias towards North America, Europe and Australia. Most studies have focused on determining whether there is a negative effect of tagging relative to control fish, with proportionally fewer that have contrasted different aspects of the surgical procedure (e.g., methods of sterilization, incision location, wound closure material) that could advance the discipline. Many of these studies included routine endpoints such as mortality, growth, healing and tag retention, with fewer addressing sublethal measures such as swimming ability, predator avoidance, physiological costs, or fitness. Continued research is needed to further elevate the practice of electronic tag implantation in fish in order to ensure that the data generated are relevant to untagged conspecifics (i.e., no long-term behavioural or physiological consequences) and the surgical procedure does not impair the health and welfare status of the tagged fish. To that end, we advocate for i) rigorous controlled manipulations based on statistical designs that have adequate power, account for inter-individual variation, and include controls and shams, ii) studies that transcend the laboratory and the field with more studies in marine waters, iii) incorporation of knowledge and

    Trends in properties of motor gasolines for the years 1942 through 1984; diesel fuels for the years 1950 through 1983; aviation fuels for the years 1947 through 1983; and heating oils for the years 1955 through 1984, have been evaluated based upon data contained in surveys prepared and published by the National Institute for Petroleum and Energy Research (NIPER) formerly the Bartlesville Energy Technology Center (BETC). The surveys for motor gasolines were conducted under a cooperative agreement with the Coordinating Research Council (CRC) and the Bureau of Mines from 1935 through 1948 and in cooperation with the American Petroleum Institute (API) since 1948 for all surveys. The motor gasoline surveys have been published twice annually since 1935 describing the properties of motor gasolines throughout the country. Other surveys prepared in cooperation with API and the Bureau of Mines, the Energy Research and Development Administration, the Department of Energy, and currently NIPER were aviation gasolines beginning in 1947, diesel fuels in 1950, aviation turbine fuels in 1951, and heating oils, formerly burner fuel oils, in 1955. Various companies throughout the country obtain samples of motor gasolines from retail outlets and refinery samples for the other surveys, and analyze the samples using American Society for Testing and Materials (ASTM) procedures. The analytical data are sent to the Bartlesville Center for survey preparation and distribution. A summary report has been assembled from data in 83 semiannual surveys for motor gasolines that shows trends throughout the entire era from winter 19

The most important trends from 1989--1994 are ranked in order of importance as: global market; retail wheeling/open access; exempt wholesale generators (EWGs); Energy Policy Act 1992; increased competition; transmission (better access and policy changes); consolidation of industry; bulk power marketing and sales; open competitive bidding; and almost exclusive shift to large gas projects. There is shift in emphasis, and the introduction of new trends, in IPP executive prediction for the future (1995--1999). Their views, in order of importance, are: retail wheeling; increased globalization; consolidation of industry; competition and direct competition with utilities; open access transmission; restructuring of entire power utility industry; deregulation; electricity as a commodity; and unbundling of integrated monopolies.

  5. Solar cooking trends--A preliminary report

    SciTech Connect (OSTI)

    Blum, B.L.

    1992-12-31

    This report discusses early results of research on trends in solar cooking worldwide and the key factors in those trends. It is based on household interviews in Belize, Honduras and Nicaragua and mail surveys from scattered individuals and promotion projects worldwide. Household interviews from six more countries will be included in future reports. Early data indicate that where solar cooking has been introduced an immediate, rapid increase in awareness and interest in solar cooking is followed by slow, sustained growth in actual solar cooking two or three years later, after an incubation period. Access to information and affordable materials for the cookers are important. Individual users and promoters both identify similar key elements for effective promotion projects, but in current projects many are often missing. Even so, successes of these small-scale efforts verify the benefits and acceptability of solar cooking to families in many regions, and should encourage much broader promotion efforts. Future reports will explore various economic, technical, cultural and environmental factors in solar cooking use as guides for larger efforts.

    Oil and gas-fired packaged steam generators are used in many industrial plants. They generate saturated or superheated steam up to 250,000 lb/hr, 1000 psig, and 950 F. They may be used for continuous steam generation or as standby boilers in cogeneration systems. Numerous variables affect the design of this equipment. A few important considerations should be addressed at an early point by the plant engineer specifying or evaluating equipment options. These considerations include trends such as customized designs that minimize operating costs and ensure emissions regulations are met. The paper discusses efficiency considerations first.

    1997-09-01

    Increasingly, users of the Energy Information Administration`s petroleum data and analytical reports have expressed an interest in a recurring report that takes a broad view of the petroleum sector. What is sought is some perspective on the complex interrelationships that comprise an industry and markets accounting for 40 percent of the energy consumed in the United States and ranging from the drilling rig in the oil field to the pump at the local gasoline station. This report comprehensively examines historical trends, and selectively focuses on major issues and the events they represent. It analyzes different dimensions of the industry and related markets in terms of how they relate to a common theme, in this case, the volatility in petroleum markets.

  11. Historical trends and extremes in boreal Alaska river basins

    Climate change will shift the frequency, intensity, duration and persistence of extreme hydroclimate events and have particularly disastrous consequences in vulnerable systems such as the warm permafrost-dominated Interior region of boreal Alaska. This work focuses on recent research results from nonparametric trends and nonstationary generalized extreme value (GEV) analyses at eight Interior Alaskan river basins for the past 50/60 years (1954/64–2013). Trends analysis of maximum and minimum streamflow indicates a strong (>+50%) and statistically significant increase in 11-day flow events during the late fall/winter and during the snowmelt period (late April/mid-May), followed by a significant decrease in the 11-day flow events during the post-snowmelt period (late May and into the summer). The April–May–June seasonal trends show significant decreases in maximum streamflow for snowmelt dominated systems (<–50%) and glacially influenced basins (–24% to –33%). Annual maximum streamflow trends indicate that most systems are experiencing declines, while minimum flow trends are largely increasing. Nonstationary GEV analysis identifies time-dependent changes in the distribution of spring extremes for snowmelt dominated and glacially dominated systems. Temperature in spring influences the glacial and high elevation snowmelt systems and winter precipitation drives changes in the snowmelt dominated basins. The Pacific Decadal Oscillation was associated with changes occurring in snowmelt dominated systems, and the Arctic Oscillation was linked to one lake dominated basin, with half of the basins exhibiting no change in response to climate variability. The paper indicates that broad scale studies examining trend and direction of change should employ multiple methods across various scales and consider regime dependent shifts to identify and understand changes in extreme streamflow within boreal forested watersheds of Alaska.

  13. PREFERRED WATERFLOOD MANAGEMENT PRACTICES FOR THE SPRABERRY TREND AREA

    SciTech Connect (OSTI)

    David S. Schechter

    2004-08-31

    The naturally fractured Spraberry Trend Area is one of the largest reservoirs in the domestic U.S. and is the largest reservoir in area extent in the world. Production from Spraberry sands is found over a 2,500 sq. mile area and Spraberry reservoirs can be found in an eight county area in west Texas. Over 150 operators produce 65,000 barrels of oil per day (bopd) from the Spraberry Trend Area from more than 9,000 production wells. Recovery is poor, on the order of 7-10% due to the profoundly complicated nature of the reservoir, yet billions of barrels of hydrocarbons remain. We estimate over 15% of remaining reserves in domestic Class III reservoirs are in Spraberry Trend Area reservoirs. This tremendous domestic asset is a prime example of an endangered hydrocarbon resource in need of immediate technological advancements before thousands of wells are permanently abandoned. This report describes the final work of the project, ''Preferred Waterflood Management Practices for the Spraberry Trend Area.'' The objective of this project is to significantly increase field-wide production in the Spraberry Trend in a short time frame through the application of preferred practices for managing and optimizing water injection. Our goal is to dispel negative attitudes and lack of confidence in water injection and to document the methodology and results for public dissemination to motivate waterflood expansion in the Spraberry Trend. This objective has been accomplished through research in three areas: (1) detail historical review and extensive reservoir characterization, (2) production data management, and (3) field demonstration. This provides results of the final year of the three-year project for each of the three areas.

    2005-10-04

    A process is underway to develop mature, integrated methodologies to address nonproliferation issues. A variety of methodologies (both qualitative and quantitative) are being considered. All have one thing in common, a need for a consistent set of proliferation related data that can be used as a basis for application. One approach to providing a basis for predicting and evaluating future proliferation events is to understand past proliferation events, that is, the different paths that have actually been taken to acquire or attempt to acquire special nuclear material. In order to provide this information, this report describing previous material acquisition activities (obtained from open source material) has been prepared. This report describes how, based on an evaluation of historical trends in nuclear technology development, conclusions can be reached concerning: (1) The length of time it takes to acquire a technology; (2) The length of time it takes for production of special nuclear material to begin; and (3) The type of approaches taken for acquiring the technology. In addition to examining time constants, the report is intended to provide information that could be used to support the use of the different non-proliferation analysis methodologies. Accordingly, each section includes: (1) Technology description; (2) Technology origin; (3) Basic theory; (4) Important components/materials; (5) Technology development; (6) Technological difficulties involved in use; (7) Changes/improvements in technology; (8) Countries that have used/attempted to use the technology; (9) Technology Information; (10) Acquisition approaches; (11) Time constants for technology development; and (12) Required Concurrent Technologies.

  20. Trends in motor gasolines: 1942-1981

    SciTech Connect (OSTI)

    Shelton, E M; Whisman, M L; Woodward, P W

    1982-06-01

    Trends in motor gasolines for the years of 1942 through 1981 have been evaluated based upon data contained in surveys that have been prepared and published by the Bartlesville Energy Technology Center (BETC). These surveys have been published twice annually since 1935 describing the properties of motor gasolines from throughout the country. The surveys have been conducted in cooperation with the American Petroleum Institute (API) since 1948. Various companies from throughout the country obtain samples from retail outlets, analyze the samples by the American Society for Testing and Materials (ASTM) procedures, and report data to the Bartlesville center for compilation, tabulation, calculation, analysis and publication. A typical motor gasoline report covers 2400 samples from service stations throughout the country representing some 48 companies that manufacture and supply gasoline. The reports include trend charts, octane plots, and tables of test results from about a dozen different tests. From these data in 77 semiannual surveys, a summary report has thus been assembled that shows trends in motor gasolines throughout the entire era of winter 1942 to 1943 to the present. Trends of physical properties including octane numbers, antiknock ratings, distillation temperatures, Reid vapor pressure, sulfur and lead content are tabulated, plotted and discussed in the current report. Also included are trend effects of technological advances and the interactions of engine design, societal and political events and prices upon motor gasoline evolution during the 40 year period.

  1. Subsea production systems -- Trends in the nineties

    SciTech Connect (OSTI)

    Jones, J.W.

    1995-12-31

    This paper describes recent subsea production system experience, with focus on cost reduction trends which are expected to continue throughout the remainder of the decade. First, the system configuration trend from large, heavy, multi-well integrated drilling template and production/injection manifold systems to small, lightweight, ``minitemplate`` systems or clustered well manifolds with individual satellite wells is addressed. Second, several equipment technology trends are addressed including towed flowline bundles with integral manifolds, development of improved reservoir management/data acquisition tools, subsea pressure boosting to extend the reach of subsea systems, emergence of the rental tool market and ``tool pools``, ``horizontal`` trees for certain applications, and standardization of subsea components and interfaces. This paper concludes that subsea production systems have successfully demonstrated their overall reliability, and have established a proven track record over the past thirty years of field experience. System configuration and equipment technology trends in the nineties are now improving the profitability and capability of subsea production systems. Subsea production system examples are cited along with generic costs to illustrate the effectiveness of these cost reduction trends. 12 figs.

    This is the seventh edition of Trends and Balances to be presented to the staff of Oak Ridge National (ORNL) and other interested parties. Each year at the end of the planning cycle the Laboratory publishes its official planning document, the Institutional Plan. Trends and Balances is brought out as a condensation of that more formal document and is intended to provide a reference to the kinds of plans that have occupied senior laboratory management over the past year. An institution as large as ORNL changes slowly, so some of the information in this document overlaps that contained in the previous edition of Trends and Balances. Much, however, is different. A new section, for example, describes what senior Laboratory management feels are five new directions for science and technology at ORNL. This document is intended to provide new insights into the programs and structure of the Laboratory.

  3. Trends in HFE Methods and Tools and Their Applicability to Safety Reviews

    The U.S. Nuclear Regulatory Commission's (NRC) conducts human factors engineering (HFE) safety reviews of applicant submittals for new plants and for changes to existing plants. The reviews include the evaluation of the methods and tools (M&T) used by applicants as part of their HFE program. The technology used to perform HFE activities has been rapidly evolving, resulting in a whole new generation of HFE M&Ts. The objectives of this research were to identify the current trends in HFE methods and tools, determine their applicability to NRC safety reviews, and identify topics for which the NRC may need additional guidance to support the NRC's safety reviews. We conducted a survey that identified over 100 new HFE M&Ts. The M&Ts were assessed to identify general trends. Seven trends were identified: Computer Applications for Performing Traditional Analyses, Computer-Aided Design, Integration of HFE Methods and Tools, Rapid Development Engineering, Analysis of Cognitive Tasks, Use of Virtual Environments and Visualizations, and Application of Human Performance Models. We assessed each trend to determine its applicability to the NRC's review by considering (1) whether the nuclear industry is making use of M&Ts for each trend, and (2) whether M&Ts reflecting the trend can be reviewed using the current design review guidance. We concluded that M&T trends that are applicable to the commercial nuclear industry and are expected to impact safety reviews may be considered for review guidance development. Three trends fell into this category: Analysis of Cognitive Tasks, Use of Virtual Environments and Visualizations, and Application of Human Performance Models. The other trends do not need to be addressed at this time.

    2004-02-13

    This report describes the work performed during the first semi-annual third year of the project, ''Preferred Waterflood Management Practices for the Spraberry Trend Area''. The objective of this project is to significantly increase field-wide production in the Spraberry Trend in a short time frame through the application of preferred practices for managing and optimizing water injection. Our goal is to dispel negative attitudes and lack of confidence in water injection and to document the methodology and results for public dissemination to motivate waterflood expansion in the Spraberry Trend. To achieve this objective, in this period we concentrated our effort on analyzing production and injection data to optimize the reservoir management strategies for Germania Spraberry Unit. This study address the reservoir characterization and monitoring of the waterflooding project and propose alternatives of development of the current and future conditions of the reservoir to improve field performance. This research should serve as a guide for future work in reservoir simulation and can be used to evaluate various scenarios for additional development as well as to optimize the operating practices in the field. The results indicate that under the current conditions, a total of 1.410 million barrels of oil can be produced in the next 20 years through the 64 active wells and suggest that the unit can be successfully flooded with the current injection rate of 1600 BWPD and the pattern consisting of 6 injection wells aligned about 36 degrees respect to the major fracture orientation. In addition, a progress report on GSU waterflood pilot is reported for this period.

    Peterson, C.

    1980-08-21

    This report outlines major conservation trends for the four US energy consuming sectors: residential, commercial, industrial, and transportation. Tables on residential use include data on gas, electricity, and fuel oil. Data is not available for renewable sources or for bottled gas, kerosene, or propane. Commercial data is also reported for gas, electricity, and fuel oil, and total consumption is examined on a square foot basis. Industrial trends are shown for the ten most energy intensive industries. In addition, industrial efficiencies by fuel are analyzed. For the transportation sector, petroleum products (particularly gasoline) are the major fuels considered, and selected energy intensities are examined. The discussion on each sector will cover findings, data sources, and data interpretation. Recommendations on reporting are part of the residential section of this report.

  14. Current Trends in Gamma Radiation Detection for Radiological Emergency Response

    Passive and active detection of gamma rays from shielded radioactive materials, including special nuclear materials, is an important task for any radiological emergency response organization. This article reports on the current trends and status of gamma radiation detection objectives and measurement techniques as applied to nonproliferation and radiological emergencies. In recent years, since the establishment of the Domestic Nuclear Detection Office by the Department of Homeland Security, a tremendous amount of progress has been made in detection materials (scintillators, semiconductors), imaging techniques (Compton imaging, use of active masking and hybrid imaging), data acquisition systems with digital signal processing, field programmable gate arrays and embedded isotopic analysis software (viz. gamma detector response and analysis software [GADRAS]1), fast template matching, and data fusion (merging radiological data with geo-referenced maps, digital imagery to provide better situational awareness). In this stride to progress, a significant amount of interdisciplinary research and development has taken place–techniques and spin-offs from medical science (such as x-ray radiography and tomography), materials engineering (systematic planned studies on scintillators to optimize several qualities of a good scintillator, nanoparticle applications, quantum dots, and photonic crystals, just to name a few). No trend analysis of radiation detection systems would be complete without mentioning the unprecedented strategic position taken by the National Nuclear Security Administration (NNSA) to deter, detect, and interdict illicit trafficking in nuclear and other radioactive materials across international borders and through the global maritime transportation–the so-called second line of defense.

    Research in the deep terrestrial biosphere is driven by interest in novel biodiversity and metabolisms, biogeochemical cycling, and the impact of human activities on this ecosystem. As this interest continues to grow, it is important to ensure that when subsurface investigations are proposed, materials recovered from the subsurface are sampled and preserved in an appropriate manner to limit contamination and ensure preservation of accurate microbial, geochemical, and mineralogical signatures. On February 20th, 2014, a workshop on “Trends and Future Challenges in Sampling The Deep Subsurface” was coordinated in Columbus, Ohio by The Ohio State University and West Virginia University faculty, and sponsored by The Ohio State University and the Sloan Foundation’s Deep Carbon Observatory. The workshop aims were to identify and develop best practices for the collection, preservation, and analysis of terrestrial deep rock samples. This document summarizes the information shared during this workshop.

    1981-05-01

    Data on the use of natural gas, electricity, distillate and residual fuel oil, coal, and purchased coke were collected from the United States Bureau of the Census and aggregated nationally and by Census Region. Trend profiles for each fuel and industry were developed and economic, regulatory, and regional factors contributing to these trends were examined. The recession that followed the OPEC embargo in 1973 affected the industrial sector and the heavily industrialized regions of the country most severely. Both industrial production and fuel consumption fell significantly in 1975. As production recovered, spiraling fuel prices promoted conservation efforts, and overall fuel consumption remained at pre-recession levels. From 1975 to 1977 natural gas consumption decreased in almost all the industries examined with curtailments of gas supplies contributing to this trend.

    The primary objective of the research reported here is to analyze energy use trends for the entire economy and by end-use sector (residential, commercial, and industrial, and transportation). In particular, an examination of energy trends was undertaken for the period 1972 through 1982 to determine the magnitude of ''energy savings'' attributable to: (1) changes in economic activity; (2) efficiency improvements relative to the 1972 stock (including structures and capital equipment); and (3) efficiency improvements relative to 1960 to 1972 trends. In addition to identifying the measures of energy savings described above, the causes of efficiency improvement relative to 1972 are explored. For example, energy savings due to efficiency improvements in the residential sector are explained by such activities as changes in household size, migration, improved shell and appliance efficiencies, and increased wood use. For this research, Pacific Northwest Laboratory (PNL) developed a consistent methodology for analyzing energy use trends by end-use sector. Alternative measures of energy use trends (i.e., alternative base cases) were developed for the purpose of measuring energy savings. The energy use trends were calculated as the product of economic activity levels (number of households in the residential sector, square feet of floor space in the commercial sector, output in the industrial sector, and person-miles/ton-miles traveled in the transportation sector) and energy use intensities (energy use per household, energy use per square foot of commercial floor space, energy use per unit of industrial output, and energy use per mile traveled). Energy savings were then defined as differences between alternative estimates of energy use. Data and methods used to derive the alternative estimates are contained in a separate volume of this report (PNL-5026-App.).

    2007-11-12

    Mixing depth is an important quantity in the determination of air pollution concentrations. Fireweather forecasts depend strongly on estimates of the mixing depth as a means of determining the altitude and dilution (ventilation rates) of smoke plumes. The Savannah River United States Forest Service (USFS) routinely conducts prescribed fires at the Savannah River Site (SRS), a heavily wooded Department of Energy (DOE) facility located in southwest South Carolina. For many years, the Savannah River National Laboratory (SRNL) has provided forecasts of weather conditions in support of the fire program, including an estimated mixing depth using potential temperature and turbulence change with height at a given location. This paper examines trends in the average estimated mixing depth daily maximum at the SRS over an extended period of time (4.75 years) derived from numerical atmospheric simulations using two versions of the Regional Atmospheric Modeling System (RAMS). This allows for differences to be seen between the model versions, as well as trends on a multi-year time frame. In addition, comparisons of predicted mixing depth for individual days in which special balloon soundings were released are also discussed.

    This paper will complement that delivered by Thomas root by following his historical analysis of the Fifth Amendment through recent case law with an analysis of regulatory taking through environmental statutes. The discussion will center on takings of water rights through application of the Clean Water Act and the Threatened and Endangered Species Act. Although the examples used will be hypothetical, they will be based upon factual situations. Some of the issues presented for consideration will be an examination of standing of municipalities and corporations under the Fifth Amendment, federal and state legislation impacting the judicial trend toward reviving the Fifth Amendment, budgetary considerations, and convergence from focus on real property to other types of property. The author will also discuss the judicial trend in the Fifth Amendment cases from reliance on federal power to regulate to financial impact on real property resulting from regulation, and the potential for a return to the analysis of the power to regulate through a resurrection of the Tenth Amendment limitation of powers.

  9. Retrospective Evaluation of Appliance Price Trends

    SciTech Connect (OSTI)

    Dale, Larry; Antinori, Camille; McNeil, Michael; McMahon, James E.; Fujita, K. Sydny

    2008-07-20

    Real prices of major appliances (refrigerators, dishwashers, heating and cooling equipment) have been falling since the late 1970s despite increases in appliance efficiency and other quality variables. This paper demonstrates that historic increases in efficiency over time, including those resulting from minimum efficiency standards, incur smaller price increases than were expected by Department of Energy (DOE) forecasts made in conjunction with standards. This effect can be explained by technological innovation, which lowers the cost of efficiency, and by market changes contributing to lower markups and economies of scale in production of higher efficiency units. We reach four principal conclusions about appliance trends and retail price setting: 1. For the past several decades, the retail price of appliances has been steadily falling while efficiency has been increasing. 2. Past retail price predictions made by DOE analyses of efficiency standards, assuming constant prices over time, have tended to overestimate retail prices. 3. The average incremental price to increase appliance efficiency has declined over time. DOE technical support documents have typically overestimated this incremental price and retail prices. 4. Changes in retail markups and economies of scale in production of more efficient appliances may have contributed to declines in prices of efficient appliances.

Since then, the number of U.S. utilities offering green pricing programs has steadily grown. Today, more than 500 utilities in regulated electricity markets--or about 16% of all utilities nationally--offer their customers green power options. Because some of these utilities offer programs in conjunction with cooperative associations or other public power entities, the number of distinct programs is slightly more than 100. Through these programs, more than 33 million customers spanning 34 states have the ability to purchase renewable energy to meet some portion or all of their electricity needs, or make contributions to support the development of renewable energy resources. Typically, customers must pay a premium above standard electricity rates for this service.

    1984-05-01

    This report provides a very brief description of steelmaking, and an overview of comparative data, primarily related to the use of energy and materials for each of the major steelmaking processes. This is followed by a discussion of possible limitations on the use of scrap - the current raw material for electric steel - and possible technological routes for overcoming them. The economics of electric-steel production in general, and of electric minimills in particular, seem clearly established. Electric steel-making is viable in its own right. The trend toward electric steelmaking provides significant economic and competitive advantages for producers and important overall economic, environmental and energy advantages for the US at large. Conversion to electric steelmaking offers a 4 to 1 advantage in terms of the overall energy used to produce a ton of steel, and a 2 to 1 savings in energy cost for the producer. The amount of energy saved, to produce the same amount of steel in 1967 and 1980, was equivalent to 25 million tons of coal. Furthermore, the amount of old scrap used to produce a ton of steel has doubled since 1967 because of the use of electric furnaces. Using the existing scrap to produce steel would save the energy equivalent of two billion barrels of oil. 44 references, 6 figures, 7 tables.

  14. Transportation energy trends and issues through 2030

    SciTech Connect (OSTI)

    DeCicco, J.M.

    1996-12-31

    Controlling transportation energy use looms as a serious challenge for the United States in the 21st century. Demand for transportation services is steadily growing, driven by increasing population, economic activity, and incomes. Few forces presently constrain growth in travel by the energy-intensive modes of automobile, truck, and air transportation. In contrast to other sectors of the economy, transportation energy efficiency improvements are nearly stagnant. Efficiency increases are now absent in highway modes; aircraft efficiency is improving, but not enough to offset rising air travel. Transportation is also the most oil-dependent sector of the economy as well as the country`s most rapidly growing source of greenhouse gas emissions. A conservative forecast indicates US transportation energy consumption rising from 23 Quads in 1990 to roughly 36 Quads by 2030; less conservative assumptions push the total to 43 Quads by 2030. Yet opportunities exist for efficiency improvements to counter a substantial portion of this growth. The most promising options are technological, with potential long-term efficiency improvements of threefold for light vehicles, twofold for aircraft, and 65 percent for heavy trucks. Combined with system efficiency changes to help limit growth of the energy-intensive modes, transportation energy use might be cut to 19 Quads by 2030. Pursuing cost-effective strategies to move the system toward such reduced energy intensiveness would be clearly valuable for the economy and environment. This paper examines these trends and options, and offers suggestions for policies that could lead to reductions in transportation energy use and its associated problems such as greenhouse gas emissions and oil dependence risks. 24 refs., 6 figs., 3 tabs.

    This paper examines experience in solar renewable energy certificate (SREC) markets in the United States. It describes how SREC markets function--key policy design provisions, eligible technologies, state and regional eligibility rules, solar alternative compliance payments, measurement and verification methods, long-term contracting provisions, and rate caps. It also examines the trends of SREC markets--trading volumes, sourcing trends, trends in the size of solar photovoltaic (PV) systems driven by these markets, and trends in price and compliance. Throughout, the paper explores key issues and challenges facing SREC markets and attempts by policymakers to address some of these market barriers. Data and information presented in this report are derived from SREC tracking systems, brokers and auctions, published reports, and information gleaned from market participants and interviews with state regulators responsible for SREC market implementation. The last section summarizes key findings.

  4. An Examination of Temporal Trends in Electricity Reliability Based on Reports from U.S. Electric Utilities

    SciTech Connect (OSTI)

    Eto, Joseph H.; LaCommare, Kristina Hamachi; Larsen, Peter; Todd, Annika; Fisher, Emily

    2012-01-06

    Since the 1960s, the U.S. electric power system has experienced a major blackout about once every 10 years. Each has been a vivid reminder of the importance society places on the continuous availability of electricity and has led to calls for changes to enhance reliability. At the root of these calls are judgments about what reliability is worth and how much should be paid to ensure it. In principle, comprehensive information on the actual reliability of the electric power system and on how proposed changes would affect reliability ought to help inform these judgments. Yet, comprehensive, national-scale information on the reliability of the U.S. electric power system is lacking. This report helps to address this information gap by assessing trends in U.S. electricity reliability based on information reported by electric utilities on power interruptions experienced by their customers. Our research augments prior investigations, which focused only on power interruptions originating in the bulk power system, by considering interruptions originating both from the bulk power system and from within local distribution systems. Our research also accounts for differences among utility reliability reporting practices by employing statistical techniques that remove the influence of these differences on the trends that we identify. The research analyzes up to 10 years of electricity reliability information collected from 155 U.S. electric utilities, which together account for roughly 50% of total U.S. electricity sales. The questions analyzed include: 1. Are there trends in reported electricity reliability over time? 2. How are trends in reported electricity reliability affected by the installation or upgrade of an automated outage management system? 3. How are trends in reported electricity reliability affected by the use of IEEE Standard 1366-2003?

    DOE Public Access Gateway for Energy & Science Beta (PAGES Beta)

    2014-01-29

    We demonstrate that porous graphene can efficiently separate gases according to their molecular sizes using molecular dynamic (MD) simulations,. The flux sequence from the classical MD simulation is H2>CO2>>N2>Ar>CH4, which generally follows the trend in the kinetic diameters. Moreover, this trend is also confirmed from the fluxes based on the computed free energy barriers for gas permeation using the umbrella sampling method and kinetic theory of gases. Both brute-force MD simulations and free-energy calcualtions lead to the flux trend consistent with experiments. Case studies of two compositions of CO2/N2 mixtures further demonstrate the separation capability of nanoporous graphene.

  16. Gender Trends in Radiation Oncology in the United States: A 30-Year Analysis

    SciTech Connect (OSTI)

    Ahmed, Awad A.; Egleston, Brian; Holliday, Emma; Eastwick, Gary; Takita, Cristiane; Jagsi, Reshma

    2014-01-01

    Purpose: Although considerable research exists regarding the role of women in the medical profession in the United States, little work has described the participation of women in academic radiation oncology. We examined women's participation in authorship of radiation oncology literature, a visible and influential activity that merits specific attention. Methods and Materials: We examined the gender of first and senior US physician-authors of articles published in the Red Journal in 1980, 1990, 2000, 2004, 2010, and 2012. The significance of trends over time was evaluated using logistic regression. Results were compared with female representation in journals of general medicine and other major medical specialties. Findings were also placed in the context of trends in the representation of women among radiation oncology faculty and residents over the past 3 decades, using Association of American Medical Colleges data. Results: The proportion of women among Red Journal first authors increased from 13.4% in 1980 to 29.7% in 2012, and the proportion among senior authors increased from 3.2% to 22.6%. The proportion of women among radiation oncology full-time faculty increased from 11% to 26.7% from 1980 to 2012. The proportion of women among radiation oncology residents increased from 27.1% to 33.3% from 1980 to 2010. Conclusions: Female first and senior authorship in the Red Journal has increased significantly, as has women's participation among full-time faculty, but women remain underrepresented among radiation oncology residents compared with their representation in the medical student body. Understanding such trends is necessary to develop appropriately targeted interventions to improve gender equity in radiation oncology.

  18. Smoothing method aids gas-inventory variance trending

    SciTech Connect (OSTI)

    Mason, R.G. )

    1992-03-23

    This paper reports on a method for determining gas-storage inventory and variance in a natural-gas storage field which uses the equations developed to determine gas-in-place in a production field. The calculations use acquired data for shut-in pressures, reservoir pore volume, and storage gas properties. These calculations are then graphed and trends are developed. Evaluating trends in inventory variance can be enhanced by use of a technique, described here, that smooths the peaks and valleys of an inventory-variance curve. Calculations using the acquired data determine inventory for a storage field whose drive mechanism is gas expansion (that is, volumetric). When used for a dry gas, condensate, or gas-condensate reservoir, the formulas require no further modification. Inventory in depleted oil fields can be determined in this same manner, as well. Some additional calculations, however, must be made to assess the influence of oil production on the gas-storage process.

  3. Water Quality Trends in the Entiat River Subbasin: Final 2008 Annual Report.

    Woodsmith, Richard; Bookter, Andy

    2009-03-30

    The ISEMP program monitors the status and trend of water quality elements that may affect restoration project effectiveness in the Entiat subbasin. As part of this effort, the PNW Research Station (PNW) measures, analyzes and interprets temporal trends in natural stream water pH, dissolved oxygen, specific conductivity and temperature. The Entiat River is currently on the Clean Water Act 303(d) list for pH exceedence, and there is insufficient information to determine the spatial and temporal extent or potential causes of this exceedence. In the spring 2008, PNW redeployed data-logging, multiparameter probes at four locations in the Entiat subbasin to measure water quality parameters, focusing on pH. This resumed previous data collection that was interrupted by river ice in early December 2007. Instruments were again removed from the river in early December 2008. This annual report covers the period from December 2007 through December 2008. The highest pH values occurred during the low-flow period from midsummer through the following midspring then dropped sharply during the annual snowmelt runoff period from late spring through early summer. Water temperature began rapidly increasing during the receding limb of the annual snowmelt hydrograph. Highest mean monthly temperatures occurred in July and August, while instantaneous maxima occurred during the period July-September. Dissolved oxygen reached its lowest levels during the period of highest water temperature in July-September. Specific conductivity remained very low at all sites throughout the year.

  6. Scaling trends in SET pulse widths in Sub-100 nm bulk CMOS processes.

    Digital single-event transient (SET) measurements in a bulk 65-nm process are compared to transients measured in 130-nm and 90-nm processes. The measured SET widths are shorter in a 65-nm test circuit than SETs measured in similar 90-nm and 130-nm circuits, but, when the factors affecting the SET width measurements (in particular pulse broadening and the parasitic bipolar effect) are considered, the actual SET width trends are found to be more complex. The differences in the SET widths between test circuits can be attributed in part to differences in n-well contact area. These results help explain some of the inconsistencies in SET measurements presented by various researchers over the past few years.

    C. M. Sizemore; David S. Schechter

    2003-08-13

    This report describes the work performed during the second year of the project, ''Preferred Waterflood Management Practices for the Spraberry Trend Area''. The objective of this project is to significantly increase field-wide production in the Spraberry Trend in a short time frame through the application of preferred practices for managing and optimizing water injection. Our goal is to dispel negative attitudes and lack of confidence in water injection and to document the methodology and results for public dissemination to motivate waterflood expansion in the Spraberry Trend. To achieve this objective, in this period we concentrated our effort on characterization of Germania Unit using an analog field ET ODaniel unit and old cased hole neutron. Petrophysical Characterization of the Germania Spraberry units requires a unique approach for a number of reasons--limited core data, lack of modern log data and absence of directed studies within the unit. The need for characterization of the Germania unit has emerged as a first step in the review, understanding and enhancement of the production practices applicable within the unit and the trend area in general. In the absence or lack of the afore mentioned resources, an approach that will rely heavily on previous petrophysical work carried out in the neighboring ET O'Daniel unit (6.2 miles away), and normalization of the old log data prior to conventional interpretation techniques will be used. A log-based rock model has been able to guide successfully the prediction of pay and non-pay intervals within the ET O'Daniel unit, and will be useful if found applicable within the Germania unit. A novel multiple regression technique utilizing non-parametric transformations to achieve better correlations in predicting a dependent variable (permeability) from multiple independent variables (rock type, shale volume and porosity) will also be investigated in this study. A log data base includes digitized formats of Gamma Ray, Cased
