    This report is the work of a panel of eight US scientists who surveyed and assessed Soviet research in the spare sciences. All of the panelists were very familiar with Soviet research through their knowledge of the published scientific literature and personal contacts with Soviet and other foreign colleagues. In addition, all of the panelists reviewed considerable additional open literature--scientific, and popular, including news releases. The specific disciplines of Soviet space science research examined in detail for the report were: solar-terrestrial research, lunar and planetary research, space astronomy and astrophysics, and, life sciences. The Soviet Union has in the past carried out an ambitious program in lunar exploration and, more recently, in studies of the inner planets, Mars and especially Venus. The Soviets have provided scientific data about the latter planet which has been crucial for studies of the planet's evolution. Future programs envision an encounter with Halley's Comet, in March 1986, and missions to Mars and asteroids. The Soviet programs in the life sciences and solar-terrestrial research have been long-lasting and systematically pursued. Much of the ground-based and space-based research in these two disciplines appears to be motivated by the requirement to establish long-term human habitation in near-Earth space. The Soviet contributions to new discoveries and understanding in observational space astronomy and astrophysics have been few. This is in significant contrast to the very excellent theoretical work contributed by Soviet scientists in this discipline.

    This report assesses the state of the art in several areas of climate research in the former Soviet Union. This assessment was performed by a group of six internationally recognized US experts in related fields. The areas chosen for review are: large-scale circulation processes in the atmosphere and oceans; atmospheric radiative processes; cloud formation processes; climate effects of natural atmospheric disturbances; and the carbon cycle, paleoclimates, and general circulation model validation. The study found an active research community in each of the above areas. Overall, the quality of climate research in the former Soviet Union is mixed, although the best Soviet work is as good as the best corresponding work in the West. The best Soviet efforts have principally been in theoretical studies or data analysis. However, an apparent lack of access to modern computing facilities has severely hampered the Soviet research. Most of the issues considered in the Soviet literature are known, and have been discussed in the Western literature, although some extraordinary research in paleoclimatology was noted. Little unusual and exceptionally creative material was found in the other areas during the study period (1985 through 1992). Scientists in the former Soviet Union have closely followed the Western literature and technology. Given their strengths in theoretical and analytical methods, as well as their possession of simplified versions of detailed computer models being used in the West, researchers in the former Soviet Union have the potential to make significant contributions if supercomputers, workstations, and software become available. However, given the current state of the economy in the former Soviet Union, it is not clear that the computer gap will be bridged in the foreseeable future.

    This assessment of recent data compression and coding research outside the United States examines fundamental and applied work in the basic areas of signal decomposition, quantization, lossless compression, and error control, as well as application development efforts in image/video compression and speech/audio compression. Seven computer scientists and engineers who are active in development of these technologies in US academia, government, and industry carried out the assessment. Strong industrial and academic research groups in Western Europe, Israel, and the Pacific Rim are active in the worldwide search for compression algorithms that provide good tradeoffs among fidelity, bit rate, and computational complexity, though the theoretical roots and virtually all of the classical compression algorithms were developed in the United States. Certain areas, such as segmentation coding, model-based coding, and trellis-coded modulation, have developed earlier or in more depth outside the United States, though the United States has maintained its early lead in most areas of theory and algorithm development. Researchers abroad are active in other currently popular areas, such as quantizer design techniques based on neural networks and signal decompositions based on fractals and wavelets, but, in most cases, either similar research is or has been going on in the United States, or the work has not led to useful improvements in compression performance. Because there is a high degree of international cooperation and interaction in this field, good ideas spread rapidly across borders (both ways) through international conferences, journals, and technical exchanges. Though there have been no fundamental data compression breakthroughs in the past five years--outside or inside the United State--there have been an enormous number of significant improvements in both places in the tradeoffs among fidelity, bit rate, and computational complexity.

    MELCOR is a fully integrated, engineering-level computer code that models the progression of severe accidents in light water reactor (LWR) nuclear power plants, which is being developed at Sandia National Laboratories for the US Nuclear Regulatory Commission (US-NRC). The entire spectrum of severe accident phenomena, including reactor coolant system and containment thermal/hydraulic response, core heatup, degradation and relocation, and fission product release and transport, is treated in MELCOR in a unified framework for both boiling water reactors (PRWs). The MELCOR computer code has been developed to the point that is now being successfully applied in severe accident analyses, particularly in probabilistic risk assessment (PRA) studies. MELCOR was the first of the severe accident analysis code to undergo a formal peer review process. One of the major conclusions of the recent MELCOR Peer Review was the need for a more comprehensive and more systematic program of MELCOR assessment. This report provides a discussion of this technical assessment.

    2011-09-01

    Adverse events in surgery have highlighted the importance of non-technical skills, such as communication, decision-making, teamwork, situational awareness and leadership, to effective organizational performance. These skills carry particular importance to surgical oncology, as members of a multidisciplinary team must work cohesively to formulate effective patient care plans. Several non-technical skills evaluation tools have been developed for use in surgery, without adequate comparison and consensus on which should be standard for training. Eleven articles describing the use of three non-technical evaluation tools related to surgery: NOTSS (Non Technical Skills for Surgeons), NOTECHS (Non Technical Skills) and OTAS (Observational Teamwork Assessment for Surgery) were analyzed with respect to scale formulation, validity, reliability and feasibility. Furthermore, their use in training thus far and the future of non-technical rating scales in surgical curricula was discussed. Future work should focus on incorporating these assessment tools into training and into a real operating room setting to provide formative evaluations for surgical residents. PMID:21129950

    This document is an initial energy assessment for American Samoa, the first of many steps in developing a comprehensive energy strategy. On March 1, 2010, Assistant Secretary of the Interior Tony Babauta invited governors and their staff from the Interior Insular Areas to meet with senior principals at the National Renewable Energy Laboratory (NREL). Meeting discussions focused on ways to improve energy efficiency and increase the deployment of renewable energy technologies in the U.S. Pacific Territories. In attendance were Governors Felix Camacho (Guam), Benigno Fitial (Commonwealth of the Northern Mariana Islands), and Togiola Tulafono, (American Samoa). This meeting brought together major stakeholders to learn and understand the importance of developing a comprehensive strategic plan for implementing energy efficiency measures and renewable energy technologies. For several decades, dependence on fossil fuels and the burden of high oil prices have been a major concern but never more at the forefront as today. With unstable oil prices, the volatility of fuel supply and the economic instability in American Samoa, energy issues are a high priority. In short, energy security is critical to American Samoa's future economic development and sustainability. Under an interagency agreement, funded by the Department of Interior's Office of Insular Affairs, NREL was tasked to deliver technical assistance to the islands of American Samoa. Technical assistance included conducting an initial technical assessment to define energy consumption and production data, establish an energy consumption baseline, and assist with the development of a strategic plan. The assessment and strategic plan will be used to assist with the transition to a cleaner energy economy. NREL provided an interdisciplinary team to cover each relevant technical area for the initial energy assessments. Experts in the following disciplines traveled to American Samoa for on-island site assessments: (1) Energy

    This report (Nuclear Power Plant Security Assessment Technical Manual) is a revision to NUREG/CR-1345 (Nuclear Power Plant Design Concepts for Sabotage Protection) that was published in January 1981. It provides conceptual and specific technical guidance for U.S. Nuclear Regulatory Commission nuclear power plant design certification and combined operating license applicants as they: (1) develop the layout of a facility (i.e., how buildings are arranged on the site property and how they are arranged internally) to enhance protection against sabotage and facilitate the use of physical security features; (2) design the physical protection system to be used at the facility; and (3) analyze the effectiveness of the PPS against the design basis threat. It should be used as a technical manual in conjunction with the 'Nuclear Power Plant Security Assessment Format and Content Guide'. The opportunity to optimize physical protection in the design of a nuclear power plant is obtained when an applicant utilizes both documents when performing a security assessment. This document provides a set of best practices that incorporates knowledge gained from more than 30 years of physical protection system design and evaluation activities at Sandia National Laboratories and insights derived from U.S. Nuclear Regulatory Commission technical staff into a manual that describes a development and analysis process of physical protection systems suitable for future nuclear power plants. In addition, selected security system technologies that may be used in a physical protection system are discussed. The scope of this document is limited to the identification of a set of best practices associated with the design and evaluation of physical security at future nuclear power plants in general. As such, it does not provide specific recommendations for the design and evaluation of physical security for any specific reactor design. These best practices should be applicable to the design and

    2015-01-01

    A review by Catchpole et al (2009) into the causes and types of harm experienced by the surgical patient emphasised the high risk nature of the perioperative period. Investigations into recent failures at NHS organisations have emphasised the relevance of non-technical skills education in improving clinical performance and patient outcomes. However, scrub practitioner non-technical skills are often developed on a tacit basis, making assessment of performance difficult. This literature review identifies strategies that facilitate assessment of non-technical skills during surgery. Recommendations are made that will assist scrub practitioners in using a validated scrub practitioner non-technical skills assessment framework reliably. PMID:26016259

    This report describes the results of investigations performed by the Georgia Tech Research Institute (GTRI) and the National Center for Atmospheric Research (NCAR) under a task entitled 'Pulsed Lidar Performance/Technical Maturity Assessment' funded by the Crew Systems Branch of the Airborne Systems Competency at the NASA Langley Research Center. The investigations included two tasks, 1.1(a) and 1.1(b). The Tasks discussed in this report are in support of the NASA Virtual Airspace Modeling and Simulation (VAMS) program and are designed to evaluate a pulsed lidar that will be required for active wake vortex avoidance solutions. The Coherent Technologies, Inc. (CTI) WindTracer LIDAR is an eye-safe, 2-micron, coherent, pulsed Doppler lidar with wake tracking capability. The actual performance of the WindTracer system was to be quantified. In addition, the sensor performance has been assessed and modeled, and the models have been included in simulation efforts. The WindTracer LIDAR was purchased by the Federal Aviation Administration (FAA) for use in near-term field data collection efforts as part of a joint NASA/FAA wake vortex research program. In the joint research program, a minimum common wake and weather data collection platform will be defined. NASA Langley will use the field data to support wake model development and operational concept investigation in support of the VAMS project, where the ultimate goal is to improve airport capacity and safety. Task 1.1(a), performed by NCAR in Boulder, Colorado to analyze the lidar system to determine its performance and capabilities based on results from simulated lidar data with analytic wake vortex models provided by NASA, which were then compared to the vendor's claims for the operational specifications of the lidar. Task 1.1(a) is described in Section 3, including the vortex model, lidar parameters and simulations, and results for both detection and tracking of wake vortices generated by Boeing 737s and 747s.

    2005-02-01

    Investigation of the literature pertaining to lunar base (LB) missions and the technologies required for LB development has revealed an information gap that hinders technical feasibility assessment. This information gap is the absence of technical readiness levels (TRL) (Mankins, 1995) and information pertaining to the criticality of the critical enabling technologies (CETs) that enable mission success. TRL is a means of identifying technical readiness stages of a technology. Criticality is defined as the level of influence the CET has on the mission scenario. The hypothesis of this research study is that technical feasibility is a function of technical readiness and technical readiness is a function of criticality. A newly developed research analysis method is used to identify the technical feasibility of LB mission scenarios. A Delphi is used to ascertain technical readiness levels and CET criticality-to-mission. The research analysis method is applied to the Delphi results to determine the technical feasibility of the LB mission scenarios that include: observatory, science research, lunar settlement, space exploration gateway, space resource utilization, and space tourism. The CETs identified encompasses four major system level technologies of: transportation, life support, structures, and power systems. Results of the technical feasibility assessment show the observatory and science research LB mission scenarios to be more technical ready out of all the scenarios, but all mission scenarios are in very close proximity to each other in regard to criticality and TRL and no one mission scenario stands out as being absolutely more technically ready than any of the other scenarios. What is significant and of value are the Delphi results concerning CET criticality-to-mission and the TRL values evidenced in the Tables that can be used by anyone assessing the technical feasibility of LB missions.

    2013-04-01

    Since the incorporation of workplace-based assessment within the specialty training programme in obstetrics and gynaecology, the assessment of technical competence to carry out caesarean section has been undertaken by the Objective Structured Assessment of Technical Skill tool. This requirement has been formalised in the Matrix of Educational Progression, ensuring that the tool must assess trainees' technical competence in caesarean section procedures of varying levels of complexity throughout training. Trainee feedback suggests that the effectiveness of the tool diminishes as the seniority of the trainee increases, with technical competence assessed less effectively in more complex procedures. This seems to be a result of the generic design of the tool and insufficient training on the part of assessors. Both of these are due to be addressed within a division of the Objective Structured Assessment of Technical Skill tool into explicitly formative and summative assessments of technical skill, following a General Medical Council-led consultation on the future of workplace-based assessment.

    A technical maturity assessment method was performed by systems engineers in collaboration with an advisory panel composed of team members from different Department of Energy sites and from different engineering and science disciplines. Various stabilization technologies were assessed annually as to their relative maturity and availability for use in stabilizing nuclear materials. After three years of assessments, several of the technologies are now components of operational systems. A regression analysis of the historical assessments was performed, and it was concluded that the numerical technical maturity score produced by a team of experts can provide a powerful predictor of the time remaining until the operational application of technologies.

    The U.S. Department of Energy's Office of Environmental Management (DOE-EM) was established to achieve the safe and compliant disposition of legacy wastes and facilities from defense nuclear applications. A large majority of these wastes and facilities are 'one-of-a-kind' and unique to DOE. Many of the programs to treat these wastes have been 'first-of-a-kind' and unprecedented in scope and complexity. This has meant that many of the technologies needed to successfully disposition these wastes were not yet developed or required significant re-engineering to be adapted for DOE-EM's needs. The DOE-EM program believes strongly in reducing the technical risk of its projects and has initiated several efforts to reduce those risks: (1) Technology Readiness Assessments to reduce the risks of deployment of new technologies; (2) External Technical Reviews as one of several steps to ensure the timely resolution of engineering and technology issues; and (3) Technical Risk Ratings as a means to monitor and communicate information about technical risks. This paper will present examples of how Technology Readiness Assessments, External Technical Reviews, and Technical Risk Ratings are being used by DOE-EM to reduce technical risks.

  4. 2011 PERFORMANCE ASSESSMENT COMMUNITY OF PRACTICE TECHNICAL EXCHANGE - SUMMARY

    SciTech Connect

    Seitz, R.

    2011-12-30

    The Performance Assessment Community of Practice (PA CoP) was developed in 2008 to improve consistency and quality in the preparation of performance assessments (PAs) and risk assessments across the Department of Energy (DOE) Complex. The term, PA, is used to represent all of these modeling applications in this report. The PA CoP goals are to foster the exchange of information among PA practitioners and to share lessons learned from PAs conducted for DOE, commercial disposal facilities, and international entities. Technical exchanges and workshops are a cornerstone of PA CoP activities. Previous technical exchanges have addressed Engineered Barriers (2009 - http://www.cresp.org/education/workshops/pacop/), the Advanced Simulation Capability for Environmental Management and the Cementitious Barriers Partnership (2010 - http://srnl.doe.gov/copexchange/links.htm). Each technical exchange also includes summary presentations regarding activities at DOE, the Nuclear Regulatory Commission (NRC) and other organizations (e.g., International Atomic Energy Agency (IAEA)) as well as a number of presentations from selected sites to provide insight and perspective from on-going modeling activities. Through the deployment of PA Assistance Teams, the PA CoP has also been engaged in the development of new PAs across the DOE Complex. As a way of improving consistency in the preparation of new PAs, the teams provide technical advice and share experiences, noteworthy practices, and lessons learned from previous Low-Level Waste Disposal Facility Federal Review Group (LFRG) reviews. Teams have provided support for PAs at Hanford, Idaho, Paducah and Portsmouth. The third annual PA CoP Technical Exchange was held on May 25-26, 2011 in Atlanta, GA. The PA CoP Steering Committee Meeting held its first meeting on May 24 prior to the Technical Exchange. Decision making using models and software quality assurance were the topical emphasis for the exchange. A new feature at the 2011 technical

  12. Technical assessment of maglev system concepts. Final report

    SciTech Connect

    Lever, J.H.

    1998-10-01

    The Government Maglev System Assessment Team operated from 1991 to 1993 as part of the National Maglev Initiative. They assessed the technical viability of four US Maglev system concepts, using the French TGV high speed train and the German TR07 Maglev system as assessment baselines. Maglev in general offers advantages that include high speed potential, excellent system control, high capacity, low energy consumption, low maintenance, modest land requirements, low operating costs, and ability to meet a variety of transportation missions. Further, the US Maglev concepts could provide superior performance to TR07 for similar cost or similar performance for less cost. They also could achieve both lower trip times and lower energy consumption along typical US routes. These advantages result generally from the use of large gap magnetic suspensions, more powerful linear synchronous motors and tilting vehicles. Innovative concepts for motors, guideways, suspension, and superconducting magnets all contribute to a potential for superior long term performance of US Maglev systems compared with TGV and TR07.

  15. Technical and operational assessment of molecular nanotechnology for space operations

    NASA Astrophysics Data System (ADS)

    McKendree, Thomas Lawrence

    2001-07-01

    This study assesses the performance of conventional technology and three levels of molecular nanotechnology (MNT) for space operations. The measures of effectiveness are technical performance parameters for five space transportation architectures, and the total logistics cost for an evaluation scenario with mining, market and factory locations on the Moon, Mars and asteroids. On these measures of effectiveness, improvements of 2--4 orders of magnitude are seen in chemical rockets, solar electric ion engines, solar sail accelerations (but not transit times), and in structural masses for planetary skyhooks and towers. Improvements in tether performance and logistics costs are nearer to 1 order of magnitude. Appendices suggest additional improvements may be possible in space mining, closed-environment life support, flexible operations, and with other space transportation architectures. In order to assess logistics cost, this research extends the facility location problem of location theory to orbital space. This extension supports optimal siting of a single facility serving circular, coplanar orbits, locations in elliptic planetary and moon orbits, and heuristic siting of multiple facilities. It focuses on conventional rocket transportation, and on high performance rockets supplying at least 1 m/s2 acceleration and 500,000 m/s exhaust velocity. Mathematica implementations are provided in appendices. Simple MNT allows diamond and buckytube construction. The main benefits are in chemical rocket performance, solar panel specific power, solar electric ion engine performance, and skyhook and tower structural masses. Complex MNT allows very small machinery, permitting large increases in solar panel specific power, which enables solar electric ion engines that are high performance rockets, and thus reduces total logistics costs an order of magnitude. Most Advance MNT allows molecular manufacturing, which enables self-repair, provides at least marginal improvements in nearly

    Dvorak, J

    1996-11-01

    In analysis of the cervical and cervicobrachial syndrome with or without signs of compression of the nerve root or spinal cord, functional assessment of the cervical spine is of great importance. Comparisons between actively performed and passively induced motion can be verified by using standardized computer-assisted assessment allowing precise documentation of the range of motion and coupled motion. The age-related normal values should be considered. The neurological assessment includes not only the cranial nerves and upper extremities but also lower extremities to avoid overlooking the signs of cervical myelopathy. In patients with compression of nerve roots or the spinal cord neurophysiology might be helpful in identifying or verifying compression. In patients with suspected myelopathy sensory evoked potentials will allow assessment of the function of the ascending spinal pathways and motor evoked potentials, assessment of the function of the descending cortical spinal pathways.

    This is the Final Report for the Louisiana Industrial Assessment Center for the period of 9/1/2002 through 11/30/2006, although we were still gathering data through 02/16/2007. During this period, our Industrial Assessment Center completed 109 energy assessments for manufacturing firms in our area, offered 3 Save Energy Workshops, taught 26 students (9 graduate and 17 undergraduate) energy management savings techniques and offered an Energy Management Graduate class three times. These 109 energy assessments made a total of 738 energy savings recommendations, 33 waste reduction recommendations, and 108 productivity improvement recommendations. These combined recommendations would save client companies more than $87,741,221.16, annually at the then current energy costs. If all of these recommendations were implemented separately, the implementation cost would have been $34,113,482.10 or a Simple Payback Period, SPP=4.7 months. Between 9 months and 12 months after the assessment, we surveyed the manufacturing firms to find out what they implemented. They had implemented approximately 50 percent of our recommendations at an annual saving of $25,867,613.18. The three Save Energy Workshops had an average attendance of twelve individuals. The three graduate Energy Management courses had an average attendance of eleven students.

    A transutilitarian rationale is proposed for assessing human spaceflight that is based on objectives for these endeavors and ethical norms of conduct. Specific attention is given to: presupposed/tacit reasons for including man in spaceflight and the restricted notion of rational/justifiable activity. It is shown that economic rationale is insufficient and unsuitable as a means for assessing manned spaceflight, and transutilitarian objectives are compiled that contribute to the motivation for manned flight. The transutilitarian motivations include: pioneering uncharted territory, enhancing national prestige, establishing space-related autonomy, promoting international cooperation, and enhancing science and the quality of human life.

  9. Technical and clinical view on ambulatory assessment in Parkinson's disease.

    PubMed

    Hobert, M A; Maetzler, W; Aminian, K; Chiari, L

    2014-09-01

    With the progress of technologies of recent years, methods have become available that use wearable sensors and ambulatory systems to measure aspects of--particular axial--motor function. As Parkinson's disease (PD) can be considered a model disorder for motor impairment, a significant number of studies have already been performed with these patients using such techniques. In general, motion sensors such as accelerometers and gyroscopes are used, in combination with lightweight electronics that do not interfere with normal human motion. A fundamental advantage in comparison with usual clinical assessment is that these sensors allow a more quantitative, objective, and reliable evaluation of symptoms; they have also significant advantages compared to in-lab technologies (e.g., optoelectronic motion capture) as they allow long-term monitoring under real-life conditions. In addition, based on recent findings particularly from studies using functional imaging, we learned that non-motor symptoms, specifically cognitive aspects, may be at least indirectly assessable. It is hypothesized that ambulatory quantitative assessment strategies will allow users, clinicians, and scientists in the future to gain more quantitative, unobtrusive, and everyday relevant data out of their clinical evaluation and can also be designed as pervasive (everywhere) and intensive (anytime) tools for ambulatory assessment and even rehabilitation of motor and (partly) non-motor symptoms in PD.

    The purpose of this assessment is to characterize the economic energy efficiency potential and investment requirements for space heating and hot water provided by district heat in the stock of state and municipal institutional buildings in the city of Kyiv. The assessment involves three activities. The first is a survey of state and municipal institutions to characterize the stock of institutional buildings. The second is to develop an estimate of the cost-effective efficiency potential. The third is to estimate the investment requirements to acquire the efficiency resource. Institutional buildings are defined as nonresidential buildings owned and occupied by state and municipal organizations. General categories of institutional buildings are education, healthcare, and cultural. The characterization activity provides information about the number of buildings, building floorspace, and consumption of space heating and hot water energy provided by the district system.

    The UM Industrial Assessment Center assisted 119 primary metals, automotive parts, metal casting, chemicals, forest products, agricultural, and glass manufacturers in Michigan, Ohio and Indiana to become more productive and profitable by identifying and recommending specific measures to improve energy efficiency, reduce waste and increase productivity. This directly benefits the environment by saving a total of 309,194 MMBtu of energy resulting in reduction of 0.004 metric tons of carbon emissions. The $4,618,740 implemented cost savings generated also saves jobs that are evaporating from the manufacturing industries in the US. Most importantly, the UM Industrial Assessment Center provided extremely valuable energy education to forty one UM graduate and undergraduate students. The practical experience complements their classroom education. This also has a large multiplier effect because the students take the knowledge and training with them.

    2004-02-01

    This report presents the results of the fish passage assessment as outlined as part of the Protect and Restore the Big Canyon Creek Watershed project as detailed in the CY2003 Statement of Work (SOW). As part of the Northwest Power Planning Council's Columbia Basin Fish and Wildlife Program (FWP), this project is one of Bonneville Power Administration's (BPA) many efforts at off-site mitigation for damage to salmon and steelhead runs, their migration, and wildlife habitat caused by the construction and operation of federal hydroelectric dams on the Columbia River and its tributaries. The proposed restoration activities within the Big Canyon Creek watershed follow the watershed restoration approach mandated by the Fisheries and Watershed Program. Nez Perce Tribal Fisheries/Watershed Program vision focuses on protecting, restoring, and enhancing watersheds and treaty resources within the ceded territory of the Nez Perce Tribe under the Treaty of 1855 with the United States Federal Government. The program uses a holistic approach, which encompasses entire watersheds, ridge top to ridge top, emphasizing all cultural aspects. We strive toward maximizing historic ecosystem productive health, for the restoration of anadromous and resident fish populations. The Nez Perce Tribal Fisheries/Watershed Program (NPTFWP) sponsors the Protect and Restore the Big Canyon Creek Watershed project. The NPTFWP has the authority to allocate funds under the provisions set forth in their contract with BPA. In the state of Idaho vast numbers of relatively small obstructions, such as road culverts, block thousands of miles of habitat suitable for a variety of fish species. To date, most agencies and land managers have not had sufficient, quantifiable data to adequately address these barrier sites. The ultimate objective of this comprehensive inventory and assessment was to identify all barrier crossings within the watershed. The barriers were then prioritized according to the amount of

    James, E C; Zukoski, E; Wormeck, J

    1981-02-01

    The aeroelectric solar power concept has been evaluated. The evaluation is based on a one-dimensional flow analysis which invokes the conservation of mass, momentum and energy of the fluid mixture (air, water vapor and water droplets) flowing through the powerplant. A performance evaluation computer code is developed which can be used to assess the concept under diverse conditions and in preliminary design. For purposes of this evaluation, the geometry of the powerplant has been specified. Aerodynamic flow losses have been estimated using a compendium of pipe flow data for each component of the power plant. These losses are utilized in the flow analysis. Flow losses have been estimated to be approximately one-third of the stream's dynamic pressure (1/2 pu/sup 2/) in the tower's cylinder section. Geometric or configuration changes can be made to reduce aerodynamic loss.

  9. Notional Scoring for Technical Review Weighting As Applied to Simulation Credibility Assessment

    NASA Technical Reports Server (NTRS)

    Hale, Joseph Peter; Hartway, Bobby; Thomas, Danny

    2008-01-01

    NASA's Modeling and Simulation Standard requires a credibility assessment for critical engineering data produced by models and simulations. Credibility assessment is thus a "qualifyingfactor" in reporting results from simulation-based analysis. The degree to which assessors should be independent of the simulation developers, users and decision makers is a recurring question. This paper provides alternative "weighting algorithms" for calculating the value-added for independence of the levels of technical review defined for the NASA Modeling and Simulation Standard.

    The U.S. Agency for International Development (USAID), through their partnership with the U.S. Department of the Interior (DOI), requested the support of Oak Ridge National Laboratory (ORNL) to provide specialized technical assistance as part of the Smart Infrastructure for the Mekong (SIM) Program in Thailand. Introduced in July 2013 by U.S. Secretary of State John Kerry, SIM is a U.S. Government Inter-Agency program that provides Lower Mekong partner countries with targeted, demand-driven technical and scientific assistance to support environmentally sound, climate conscious and socially equitable infrastructure, clean energy development, and water resources optimization. The U.S. Government is committed to supporting sustainable economic development within the region by providing tools, best practices, technical assistance, and lessons learned for the benefit of partner countries. In response to a request from the Electricity Generating Authority of Thailand (EGAT), a SIM project was developed with two main activities: 1) to promote hydropower sustainability and efficiency through technical assessment training at two existing hydropower assets in Thailand, and 2) the design and implementation of one national and two or three regional science and policy workshops, to be co-hosted with EGAT, to build common understanding of and commitment to environmental and social safeguards for Mekong Basin hydropower projects. The U.S. Department of Energy (DOE) is leading the technical assessment (Activity 1), and has contracted ORNL to provide expert technical assistance focused on increasing efficiency at existing projects, with the goal of increasing renewable energy generation at little to no capital cost. ORNL is the leading national laboratory in hydropower analysis, with a nationally recognized and highly qualified team of scientists addressing small to large-scale systems (basin-, regional-, and national-scale) energy generation optimization analysis for DOE.

    Aim To review the literature on non-technical skills and assessment methods relevant to emergency care. Background Non-technical skills (NTS) include leadership, teamwork, decision making and situation awareness, all of which have an impact on healthcare outcomes. Significant concerns have been raised about the rates of adverse medical events, many of which are attributed to NTS failures. Methods Ovid, Medline, ProQUEST, PsycINFO and specialty websites were searched for NTS measures using applicable access strategies, inclusion and exclusion criteria. Publications identified were assessed for relevance. Results A range of non-technical skill measures relevant to emergency care was identified: leadership (n = 5), teamwork (n = 7), personality/behavior (n = 3) and situation awareness tools (n = 1). Of these, 9 have been used with emergency care populations/clinicians. All had varying degrees of reliability and validity. In the last decade there has been some development of teamwork measures specific to emergency care with a predominantly global and collective rating of broad skills. Conclusion A variety of non-technical skill measures are available; only a few have been used in the emergency care arena. There is a need for an increase in the focused assessment of teamwork skills for a greater understanding of team performance to enhance patient safety in medical emergency care. PMID:27147832

    2015-05-01

    In order to meet the environmental legislative framework in force in Europe and reduce sludge processing and disposal costs, several sludge treatment technologies and management strategies have been proposed in the last two decades. The evaluation of their technical and economic suitability, case by case, may be a challenge, since many aspects are involved, so that a robust decision support system should be used. Within the ROUTES project (founded within the EU Seventh Framework Programme), the authors have developed an assessment procedure which allows rating several technical factors (such as system reliability, complexity, safety aspects, modularity, etc.) and estimating capital and operating costs, in case a plant is being upgraded. The comparison between the original (reference) plant and the modified configuration informs about technical hot spots (which are expressed by a traffic light-type colour code) and cost gaps resulting from the implementation of the new solution.

    Objectives The objectives of the study were to identify Danish anaesthesiologists’ non-technical skills and to customise the Scottish-developed Anaesthetists’ Non-Technical Skills instrument for Danish anaesthesiologists. Methods Six semi-structured group interviews were conducted with 31 operating room team members: anaesthesiologists, nurse anaesthetists, surgeons, and scrub nurses. Interviews were transcribed verbatim and analysed using directed content analysis. Anaesthesiologists’ non-technical skills were identified, coded, and sorted using the original instrument as a basis. The resulting prototype instrument was discussed with anaesthesiologists from 17 centres to ensure face validity. Results Interviews lasted 46–67 minutes. Identified examples of anaesthesiologists’ good or poor non-technical skills fit the four categories in the original instrument: situation awareness; decision making; team working; and task management. Anaesthesiologists’ leadership role in the operating room was emphasised: the original ‘Task Management’ category was named ‘Leadership’. One new element, ‘Demonstrating self-awareness’ was added under the category ‘Situation Awareness’. Compared with the original instrument, half of the behavioural markers were new, which reflected that being aware of and communicating one’s own abilities to the team; working systematically; and speaking up to avoid adverse events were important skills. Conclusions The Anaesthetists’ Non-Technical Skills instrument was customised to a Danish setting using the identified non-technical skills for anaesthesiologists and the original instrument as basis. The customised instrument comprises four categories and 16 underpinning elements supported by multiple behavioural markers. Identifying non-technical skills through semi-structured group interviews and analysing them using direct content analysis proved a useful method for customising an assessment instrument to another

  18. Technical and Economic Assessment of Span-Loaded Cargo Aircraft Concepts

    NASA Technical Reports Server (NTRS)

    1976-01-01

    The benefits are assessed of span distributed loading concepts as applied to future commercial air cargo operations. A two phased program is used to perform this assessment. The first phase consists of selected parametric studies to define significant configuration, performance, and economic trends. The second phase consists of more detailed engineering design, analysis, and economic evaluations to define the technical and economic feasibility of a selected spanloader design. A conventional all-cargo aircraft of comparable technology and size is used as a comparator system. The technical feasibility is demonstrated of the spanloader concept with no new major technology efforts required to implement the system. However, certain high pay-off technologies such as winglets, airfoil design, and advanced structural materials and manufacturing techniques need refinement and definition prior to application. In addition, further structural design analysis could establish the techniques and criteria necessary to fully capitalize upon the high degree of structural commonality and simplicity inherent in the spanloader concept.

    A technical assessment of the continued wet storage of EBR-II fuel has been made. Previous experience has shown that in-basin cladding failure occurs by intergranular attack of sensitized cladding, likely assisted by basin water chlorides. Subsequent fuel oxidation is rapid and leads to loss of configuration and release of fission products. The current inventory of EBR-II fuel stored in the ICPP basins is at risk from similar corrosion reactions.

    Presenting science fair projects gave students an opportunity to complete a performance assessment that comprised a meaningful task focused on process and subject to standards-based assessment. Students presented science inquiry and engineering design projects to judges at a regional science fair. The judges used the domains of the Potter Rubrics to assess the students' work and assigned a Quality score to each project. Using multiple regression, this study found that the mean scores on the Methods and Analysis domains predicted the mean Quality scores. Analyzing the technical quality of the Potter Rubrics addressed some of the measurement and generalizability concerns about performance assessments. Recommendations for future research and implications for practice were examined.

  7. Technical and economic assessment of processes for the production of butanol and acetone

    NASA Technical Reports Server (NTRS)

    1982-01-01

    This report represents a preliminary technical and economic evaluation of a process which produces mixed solvents (butaol/acetone/ethanol) via fermentation of sugars derived from renewable biomass resources. The objective is to assess the technology of producing butanol/acetone from biomass, and select a viable process capable of serving as a base case model for technical and economic analysis. It is anticipated that the base case process developed herein can then be used as the basis for subsequent studies concerning biomass conversion processes capable of producing a wide range of chemicals. The general criteria utilized in determining the design basis for the process are profit potential and non-renewable energy displacement potential. The feedstock chosen, aspen wood, was selected from a number of potential renewable biomass resources as the most readily available in the United States and for its relatively large potential for producing reducing sugars.

    1993-12-01

    The primary objective of this project is to examine factors affecting technical and economic success of horizontal well applications. The project`s goals will be accomplished through five tasks designed to evaluate the technical and economic success of horizontal drilling, ascertain its limitations, and outline technical needs to overcome these limitations. Data describing operators` experiences throughout the domestic oil and gas industry will be gathered and organized. MEI databases containing detailed horizontal case histories will also be used. All these data will be categorized and analyzed to assess the status of horizontal well technology and determine the impact of horizontal wells on present and future domestic oil recovery and reserves. A spreadsheet data file was constructed from well data describing 3885 domestic horizontal wells, the total as of the summer of 1993. Most domestic effort in horizontal drilling has been focused on fractured carbonate formations. Three principal formations are the focus of this activity: The Austin Chalk in Texas, the Bakken Shale in North Dakota, and the Niobrara in Colorado and Wyoming. Results from this formation type are well known and a large volume of published results is available. Given the scope of the present study, it was decided to limit the analyses to formations other than these three fractured carbonates. Based on domestic well data, 431 horizontal wells have been completed in other formations. These wells were highlighted for detailed study.

    Background After almost a decade of implementing competency-based programs in postgraduate training programs, the assessment of technical skills remains more subjective than objective. National data on the assessment of technical skills during surgical training are lacking. We conducted this study to document the assessment tools for technical skills currently used in different surgical specialties, their relationship with remediation, the recommended tools from the program directors’ perspective, and program directors’ attitudes toward the available objective tools to assess technical skills. Methods This study was a cross-sectional survey of surgical program directors (PDs). The survey was initially developed using a focus group and was then sent to 116 PDs. The survey contains demographic information about the program, the objective assessment tools used, and the reason for not using assessment tools. The last section discusses the recommended tools to be used from the PDs’ perspective and the PDs’ attitude and motivation to apply these tools in each program. The associations between the responses to the assessment questions and remediation were statistically evaluated. Results Seventy-one (61%) participants responded. Of the respondents, 59% mentioned using only nonstandardized, subjective, direct observation for technical skills assessment. Sixty percent use only summative evaluation, whereas 15% perform only formative evaluations of their residents, and the remaining 22% conduct both summative and formative evaluations of their residents’ technical skills. Operative portfolios are kept by 53% of programs. The percentage of programs with mechanisms for remediation is 29% (19 of 65). Conclusion The survey showed that surgical training programs use different tools to assess surgical skills competency. Having a clear remediation mechanism was highly associated with reporting remediation, which reflects the capability to detect struggling residents

    1996-02-01

    The Department of Energy and its contractors are faced with environmental concerns and large waste management costs. Federal legislation and DOE Orders require sites to develop waste minimization/pollution prevention programs. In response to these requirements, the Kansas City Plant developed a pollution prevention tool called a pollution prevention opportunity assessment (PPOA). Pilot assessments resulted in the development of a graded approach to reduce the amount of effort required for activities that utilized nonhazardous and/or low-volume waste streams. The project`s objectives in FY95 were to validate DOE`s PPOA Graded Approach methodology, provide PPOA training and technical assistance to interested DOE personnel and DOE contractors, enhance the methodology with energy analysis and tools for environmental restoration activities, implement a DOE-wide PPOA database, and provide support to DOE EM-334 in the completion of a report which estimates the future potential for pollution prevention and waste minimization in the DOE complex.

    2014-01-01

    Introduction Strengthening health service delivery to the rural poor is an important means of redressing inequities. Meso-level managers can help enhance efficiency in the utilization of existing resources through the application of practical tools to analyze routinely collected data reflecting inputs and outputs. This study aimed to assess the efficiency and change in productivity of health posts over two years in a rural department of Guatemala. Methods Data envelopment analysis was used to measure health posts’ technical efficiency and productivity change for 2008 and 2009. Input/output data were collected from the regional health office of Alta Verapaz for 34 health posts from the 19 districts comprising the health region. Results Technical efficiency varied widely across health posts, with mean scores of 0.78 (SD=0.24) and 0.75 (SD=0.21) in 2008 and 2009, respectively. Overall, productivity increased by 4%, though 47% of health posts experienced a decline in productivity. Results were combined on a bivariate plot to identify health posts at the high and low extremes of efficiency, which should be followed up to determine how and why their production processes are operating differently. Conclusions Assessing efficiency using the data that are available at the meso-level can serve as a first step in strengthening performance. Further work is required to support managers in the routine application of efficiency analysis and putting the results to use in guiding efforts to improve service delivery and increase utilization.

    1993-01-01

    Since July 1992, the WHO Regional Office for Europe has been using epidemiological and public health assessment techniques to guide its interventions in the crisis in the former Yugoslavia. WHO field operations have evolved into the largest emergency relief operation ever undertaken in the European Region. The WHO programme of humanitarian assistance focuses on five major areas: public health, equipment, supplies and logistic support, support to war victims, primary health care for refugees and rehabilitation of the health care system. The main thrust of the programme is to implement the public health measures required for survival. The first step is to provide health intelligence for international humanitarian assistance programmes through health and nutrition monitoring. This leads to targeted intervention. While involved in all aspects of relief, WHO clearly justifies its presence by its technical focus, bringing its network of expertise and experience to bear on the assessment of need and the coordination of intervention. Three examples of this approach are given: the nutrition programme, which includes emergency food aid and health and nutrition monitoring, the winter protection programme in Bosnia and Herzegovina, and the medical kit programme, involving the design and use of special kits to cover basic emergency needs for medical supplies to the maximum number of people. In the former Yugoslavia, the WHO Regional Office for Europe has concentrated on technical situation analysis and sound public health grounding to guide and direct intervention. PMID:8017078

    Background: The share of healthcare-related expenditure in the Gross Domestic Product of Kazakhstan is relatively small, and it is strategically important to restructure budgetary expenses in favor of healthcare with simultaneous redistribution of resources in accordance with changing demands and prioritization of high-quality medical care. The aim of this study was to analyze resource provision to healthcare organizations in Kazakhstan and its structure and level assessment. Materials and Methods: The study is based on a comparative assessment of technical and technological equipment of medical institutions in Almaty, Kazakhstan. We analyzed the scope and structure of the financial component of the resource base in Almaty. We carried out information processing and analysis methods, content analysis, mathematical treatment, as well as conducted case studies. Also, we held opinion poll among medical staff (specialists, managerial staff) (n = 300) P for trend < 0.001 and patients (n = 210) P for trend < 0.001. Results: About 18.8% of patients do not receive medical care because of defects of the equipment, whereas 19.9% of patients claim that the reason of refusal of the provision of medical services is an equipment overload. Conclusion: Most of the respondents referred to on poor technical equipment, mismatch with the world standards of performance and competitiveness. Lack of advanced medical technology, inadequate financing, insufficient supply of domestic medical equipment, and inadequate procurement by tender were also noted. The obtained data point to the need for optimization and upgrading medical equipment at various levels of healthcare. PMID:25535494

  2. A tool for technical assessment of rural water supply systems in South Africa

    NASA Astrophysics Data System (ADS)

    Rietveld, L. C.; Haarhoff, J.; Jagals, P.

    Water and sanitation services provide a cost-effective solution for alleviating the impact of water-borne diseases. Actually, for water supply projects a top-down approach is followed, giving priority to deliver sufficient quantities of water, increasing its availability by investment in new systems. Little attention is paid to the functioning of these systems on the long-term, and its maintenance and operational constraints. In this paper, a methodology was developed to technically assess water supply systems based on four criteria, namely availability, capacity, continuity and condition. The practicality of the approach is demonstrated by a technical assessment of a number of water supply systems in the Vhembe District in South Africa. The systems consist of piped distribution systems with public standpipes, mostly fed by groundwater. In general, it can be concluded that the performance of the systems, although relatively new, is poor. The availability (criterion 1) of the drinking water is a problem due to poorly constructed boreholes or disagreement on the payment of the operational cost after construction. In most villages the capacity (criterion 2) of the installed infrastructure is sufficient, although storage volume is in some villages too small. The continuity (criterion 3) of the water supply is threatened by disputes about payment of diesel for the pump and maintenance and repair of the pump. Finally, the condition (criterion 4) is poor mostly due to taps at the standpipes which are damaged and require frequent replacement. Despite the simplicity of the proposed assessment methodology, it provides rapid insight in the state of a system and is ideal for bench marking the performance of different systems in different regions. Furthermore, the quantitative measures of the four different criteria allow system operators and planners to rapidly pinpoint the reasons for poor performance and to take the appropriate corrective action.

    Cardiovascular disease is the primary cause of mortality and a major cause of disability worldwide. The dysfunction of the vascular endothelium is a pathological condition characterized mainly by a disruption in the balance between vasodilator and vasoconstrictor substances and is proposed to play an important role in the development of atherosclerotic cardiovascular disease. Therefore, a precise evaluation of endothelial function in humans represents an important tool that could help better understand the etiology of multiple cardio-centric pathologies. Over the past twenty-five years, many methodological approaches have been developed to provide an assessment of endothelial function in humans. Introduced in 1989, the FMD test incorporates a forearm occlusion and subsequent reactive hyperemia that promotes nitric oxide production and vasodilation of the brachial artery. The FMD test is now the most widely utilized, non-invasive, ultrasonic assessment of endothelial function in humans and has been associated with future cardiovascular events. Although the FMD test could have clinical utility, it is a physiological assessment that has inherited several confounding factors that need to be considered. This article describes a standardized protocol for determining FMD including the recommended methodology to help minimize the physiological and technical issues and improve the precision and reproducibility of the assessment.

    The use of methane-related fuels, derived from a variety of sources, in highway vehicles is assessed. Methane, as used here, includes natural gas (NG) as well as synthetic natural gas (SNG). Methanol is included because it can be produced from NG or the same resources as SNG, and because it is a liquid fuel at normal ambient conditions. Technological, operational, efficiency, petroleum displacement, supply, safety, and economic issues are analyzed. In principle, both NG and methanol allow more efficient engine operation than gasoline. In practice, engines are at present rarely optimized for NG and methanol. On the basis of energy expended from resource extraction to end use, only optimized LNG vehicles are more efficient than their gasoline counterparts. By 1985, up to 16% of total petroleum-based highway vehicle fuel could be displaced by large fleets with central NG fueling depots. Excluding diesel vehicles, which need technology advances to use NG, savings of 8% are projected. Methanol use by large fleets could displace up to 8% of petroleum-based highway vehicle fuel from spark-ignition vehicles and another 9% from diesel vehicles with technology advances. The US NG supply appears adequate to accommodate fleet use. Supply projections, future price differential versus gasoline, and user economics are uncertain. In many cases, attractive paybacks can occur. Compressed NG now costs on average about $0.65 less than gasoline, per energy-equivalent gallon. Methanol supply projections, future prices, and user economics are even more uncertain. Current and projected near-term methanol supplies are far from adequate to support fleet use. Methanol presently costs more than gasoline on an equal-energy basis, but is projected to cost less if produced from coal instead of NG or petroleum.

    In order to address the issue of technological progress, most integrated assessment models have incorporated methods to account for autonomous energy efficiency improvement, the natural tendency of an economy to find more efficient ways to produce energy services. Although the treatment of technical changes as an autonomous event is a reasonable modeling convenience, it is not a statement of actual cause and effect. The purpose of this research project is to examine the responsiveness of a particular technology, solar photovoltaic electricity generation, to research and development expenditures by the government and private industry. The goal is to be able to model how the technology can be expected to respond to future government expenditures. The first step was to develop a database of government expenditures on solar photovoltaic research and development. The next step was to develop an analytical dynamic optimization model that would allow the characterization of the important factors in the R&D process and the demonstration of generalizable principles of optimal investment in the R&D process. There is now a solid starting point for research into the relation between government spending on technology research and the response of the technology in terms of technical efficiency.

    There is a critical need for standard approaches to assess, report and compare the technical performance of genome-scale differential gene expression experiments. Here we assess technical performance with a proposed standard 'dashboard' of metrics derived from analysis of external spike-in RNA control ratio mixtures. These control ratio mixtures with defined abundance ratios enable assessment of diagnostic performance of differentially expressed transcript lists, limit of detection of ratio (LODR) estimates and expression ratio variability and measurement bias. The performance metrics suite is applicable to analysis of a typical experiment, and here we also apply these metrics to evaluate technical performance among laboratories. An interlaboratory study using identical samples shared among 12 laboratories with three different measurement processes demonstrates generally consistent diagnostic power across 11 laboratories. Ratio measurement variability and bias are also comparable among laboratories for the same measurement process. We observe different biases for measurement processes using different mRNA-enrichment protocols. PMID:25254650

    In an era when health resources are increasingly constrained, international organisations are transitioning from directly managing health services to providing technical assistance (TA) to in-country owners of public health programmes. We define TA as: A dynamic, capacity-building process for designing or improving the quality, effectiveness, and efficiency of specific programmes, research, services, products, or systems’. TA can build sustainable capacities, strengthen health systems and support country ownership. However, our assessment of published evaluations found limited evidence for its effectiveness. We summarise socio-behavioural theories relevant to TA, review published evaluations and describe skills required for TA providers. We explore challenges to providing TA including cost effectiveness, knowledge management and sustaining TA systems. Lastly, we outline recommendations for structuring global TA systems. Considering its important role in global health, more rigorous evaluations of TA efforts should be given high priority. PMID:22606939

    Fundamental movement competency is essential for participation in physical activity and for mitigating the risk of injury, which are both key elements of health throughout life. The squat movement pattern is arguably one of the most primal and critical fundamental movements necessary to improve sport performance, to reduce injury risk and to support lifelong physical activity. Based on current evidence, this first (1 of 2) report deconstructs the technical performance of the back squat as a foundation training exercise and presents a novel dynamic screening tool that incorporates identification techniques for functional deficits that limit squat performance and injury resilience. The follow-up report will outline targeted corrective methodology for each of the functional deficits presented in the assessment tool. PMID:25506270

    2016-01-01

    The U.S. Geological Survey (USGS) assessed the undiscovered, technically recoverable oil and gas resources of Armenia in 2013. A Paleozoic and a Cenozoic total petroleum system (TPS) were identified within the country of Armenia. The postulated petroleum system elements are uncertain, resulting in low geologic probabilities for significant oil an gas resources. Two assessment units (AU) were delineated in each TPS—a Paleozoic-Sourced Conventional Reservoirs AU and a Permian Shale Gas AU in the Paleozoic Composite TPS and a Paleogene-Sourced Conventional Reservoirs AU and a Cenozoic Coalbed Gas AU in the Cenozoic Composite TPS. The TPS elements are largely uncertain and risked, and so only the Paleogene-Sourced Conventional Reservoirs AU was quantitatively assessed because the geologic probability is more than the threshold of 10 percent (that is, the probability of at least one conventional oil or gas accumulation of 5 million barrels of oil equivalent or greater based on postulated petroleum-system elements). The USGS estimated fully risked mean volumes of about 1 million barrels of oil (MMBO), about 6 billion cubic feet of natural gas (BCFG), and less than 1 million barrels of natural gas liquids (MMBNGL).

    1995-04-01

    The Department of Energy (DOE) has prepared a revision to DOE Order 5820.2A, entitled ``Radioactive Waste Management.`` DOE issued DOE Order 5820.2A in September 1988 and, as the title implies, it covered only radioactive waste forms. The proposed draft order, entitled ``Waste Management,`` addresses the management of both radioactive and nonradioactive waste forms. It also includes spent nuclear fuel, which DOE does not consider a waste. Waste forms covered include hazardous waste, high-level waste, transuranic (TRU) waste, low-level radioactive waste, uranium and thorium mill tailings, mixed waste, and sanitary waste. The Radioactive Waste Technical Support Program (TSP) of Leached Idaho Technologies Company (LITCO) is facilitating the revision of this order. The EM Regulatory Compliance Division (EM-331) has requested that TSP estimate the impacts and costs of compliance with the revised order. TSP requested Dames & Moore to aid in this assessment by comparing requirements in Draft Order 5820.2B to ones in DOE Order 5820.2A and other DOE orders and Federal regulations. The assessment started with a draft version of 5820.2B dated January 14, 1994. DOE has released three updated versions of the draft order since then (dated May 20, 1994; August 26, 1994; and January 23, 1995). Each time DOE revised the order, Dames and Moore updated the assessment work to reflect the text changes. This report reflects the January 23, 1995 version of the draft order.

    Developing countries that are considering the deployment of nuclear power plants (NPPs) in the near future need to perform reactor technology assessment (RTA) in order to select the most suitable reactor design. The International Atomic Energy Agency (IAEA) reported in the Common User Considerations (CUC) document that "proven technology" is one of the most important technical criteria for newcomer countries in performing the RTA. The qualitative description of five desired features for "proven technology" is relatively broad and only provides a general guideline to its characterization. This paper proposes a methodology to define the "proven technology" term according to a specific country's requirements using a three-stage evaluation process. The first evaluation stage screens the available technologies in the market against a predefined minimum Technology Readiness Level (TRL) derived as a condition based on national needs and policy objectives. The result is a list of technology options, which are then assessed in the second evaluation stage against quantitative definitions of CUC desired features for proven technology. The potential technology candidates produced from this evaluation is further narrowed down to obtain a list of proven technology candidates by assessing them against selected risk criteria and the established maximum allowable total score using a scoring matrix. The outcome of this methodology is the proven technology candidates selected using an accurate definition of "proven technology" that fulfills the policy objectives, national needs and risk, and country-specific CUC desired features of the country that performs this assessment. A simplified assessment for Malaysia is carried out to demonstrate and suggest the use of the proposed methodology. In this exercise, ABWR, AP1000, APR1400 and EPR designs assumed the top-ranks of proven technology candidates according to Malaysia's definition of "proven technology".

    INTRODUCTION Despite awareness of the limitations of current selection and competency assessments, there is little consensus and alternatives have not been readily accepted. Essential surgical skills include visuospatial and technical ability. The aim of this study was to survey current methods of higher surgical trainee selection and assessment. We suggest ways to improve the process. MATERIALS AND METHODS Nine surgical training programmes in the London deanery were surveyed through questionnaires to programme directors, existing trainees and examination of deanery publications. RESULTS Testing of visuospatial and technical ability was piloted at selection only in a single general surgical department. Practical skills were assessed in 3/9 (33%) specialties (ENT, plastic and general surgery). Once selected, no specialty tested visuospatial and technical ability. Practical skills were tested in only 1/9 (11%) specialties (plastic surgery). The remaining 8/9 (89%) were ‘assessed’ by interview. CONCLUSIONS Lack of visuospatial and technical ability assessment was identified at selection and during higher surgical training. Airlines have long recognised early identification of these qualities as critical for efficient training. There is a need for more objective methods in this area prior to selection as time to assess surgical trainees during long apprenticeships is no longer available. We advocate a suitably validated competency-based model during and at completion of training. PMID:18201473

    The paper reports on the methodology and findings of a recent project on behalf of the Austrian Federal Ministry of Agriculture, Forestry, Environment and Water Management. The Ministry is seeking procedures for combining ecological and economic criteria to assess which technical urban water alternatives shall receive funding. To this end the current decision making process (DMP) for implementing urban water alternatives in Austria has been analyzed and compared with the situation elsewhere, e.g. in Sweden. The DMP entails specific requirements on assessment, whence the most common decision aid methodologies, ranging from LCA-based to multi-criteria methods, have been described and evaluated from an environmental, economic, legal and practical point of view, turning out recommendations to the Ministry. Their main points are: First the DMP should be kept as simple as possible in order to make it transparent. Second the aggregation of different criteria groups should and can be avoided. Therefore the stakeholders should not be allowed to make trade-offs. Finally clear objectives need to be stated. PMID:16445172

    Serious pollution of SO{sub 2} and acid deposition have emerged in China in the latest decade due to the stagnant growth of coal use. As a large consumer of energy, thermal power generation takes up about 30% of the total coal consumption and will remain an increasing demand for coal over a long period. In the paper, the pollution status, trend and a series of related policy measures made by the government were presented to give the great significance to the control of SO{sub 2} emissions from power generation. Flue gas desulfurization (FGD) is widely adopted over the world to control SO{sub 2} emissions. In China, the research and development of power plant FGD technology were initiated in the mid 70`s. Especially since the 7th and 8th Five-Year plan, more efforts have been made on FGD development and introduction. The authors carried out a systematic review on the FGD technical status in China, placing an emphasis on the processes pilot tested, demonstrated, introduced and applied, such as limestone(lime)-gypsum process, lime spray drying, phosphate ammoniate compound fertilizer process, simplified wet limestone process, furnace calcium injection/post-furnace humidification and simplified combined dust/SO{sub 2} removal. The test and operation were described in details and the main technical indices were listed for the various processes. Following the technical assessment, the authors set up a methodology to gave a comparable economic evaluation on the FGD processes. Based on the methodology, unified setting of economic parameters such as discount, inflation and price of materials, the estimation was made for the FGD capital, operation cost and levelized cost. In addition, the sensitivity of main parameters such as generation installing capacity and sulfur content of coal was analyzed on the cost of SO{sub 2} removal. The results showed that the rise of power generation cost would be 0.02-0.03 Yuan/kWh and 0.01-0.02 Yuan/kWh for wet and dry FGD installations

    The service consists of a tool for quick technical and economic feasibility assessment of small hydropower sites, based on topography, hydrology, environmental flows and other constraints such as distance from existing electric grids. The system works in a web-mapping wrap and allows analysis at a scale comparable to common geo-browsing tools (such Google Earth ©), just like e.g. popular JRC's PVGIS for the estimation of photovoltaic potential. The system provides basically two levels of operation: (1) mapping of the hydropower potential at Europe or regional scale, and (2) preliminary assessment of hydropower production at a site specific level. In the first level, a map of the potential production is provided taking into account a predefined length of the diversion of water (derivation channel and penstock) and calculating related Hydraulic jump; the system combines then topographic information together with flow duration curve information for the whole European/regional stream network and operative hypothesis on maximum derivable flow and other relevant derivation parameters. In the second level user defines in detail project parameters (amount of withdrawal, length of derivation, distance from connection grid, type of turbine, local feed in tariff) and the system evaluates preliminary feasibility check (size of the plat, maximum allowed investment for a fixed for a payback time). Interface via Google Map/Earth © or similar geo-browsing tools will be provided. This tool is expected to play a role in promoting investment in pico-to micro-hydropower plants by making preliminary feasibility assessment much quicker and affordable, and providing reliable estimation of potential available resource, which may be a critical aspect in the development of small plants and for site scouting activity The research leading to these results has received funding from the European Community's Seventh Framework Programme under Grant Agreement No. 603587 (SWITCH-ON).

    In order to more fully integrate renewable resources, such as wind and solar, into the transmission system, additional capacity must be realized in the short term using the installed transmission capacity that exists today. The U.S. Department of Energy (DOE) and the National Renewable Energy Laboratory Transmission and Grid Integration Group supported this study to assemble the history of regulations and status of transmission technology to expand existing grid capacity. This report compiles data on various transmission technology methods and upgrades for increased capacity utilization of the existing transmission system and transmission corridors. The report discusses the technical merit of each method and explains how the method could be applied within the current regulatory structure to increase existing transmission conductor and/or corridor capacity. The history and current state of alternatives to new construction is presented for regulators, legislators, and other policy makers wrestling with issues surrounding integration of variable generation. Current regulations are assessed for opportunities to change them to promote grid expansion. To support consideration of these alternatives for expanding grid capacity, the report lists relevant rules, standards, and policy changes.

    Efforts are ongoing to improve outcomes from cardiac arrest and medical emergencies. A promising quality improvement modality is use of non-technical skills (NTS) that aim to address human factors through improvements in performance of leadership, communication, situational awareness and decision-making. Originating in the airline industry, NTS training has been successfully introduced into anaesthesia, surgery, emergency medicine and other acute medical specialities. Some aspects of NTS have already achieved acceptance for cardiac arrest teams. Leadership skills are emphasised in advanced life support training and have shown favourable results when employed in simulated and clinical resuscitation scenarios. The application of NTS in medical emergency teams as part of a rapid response system attending medical emergencies is less certain; however, observations of simulations have also shown promise. This review highlights the potential benefits of NTS competency for cardiac arrest teams and, more importantly, medical emergency teams because of the diversity of clinical scenarios encountered. Discussion covers methods to assess and refine NTS and NTS training to optimise performance in the clinical environment. Increasing attention should be applied to yielding meaningful patient and organisational outcomes from use of NTS. Similarly, implementation of any training course should receive appropriate scrutiny to refine team and institutional performance. PMID:23611153

    Studies have been performed to assess the industrial perspectives of partitioning and transmutation of long-lived elements. These studies were carried out in tight connection with GEN-IV systems development. The results include the technical and economic evaluation of fuel cycle scenarios along with different options for optimizing the processes between the minor actinide transmutation in fast neutron reactors, their interim storage and geological disposal of ultimate waste. The results are analysed through several criteria (impacts on waste, on waste repository, on fuel cycle plants, on radiological exposure of workers, on costs and on industrial risks). These scenario evaluations take place in the French context which considers the deployment of the first Sodium-cooled Fast Reactor (SFR) in 2040. 3 management options of minor actinides have been studied: no transmutation, transmutation in SFR and transmutation in an accelerator-driven system (ADS). Concerning economics the study shows that the cost overrun related to the transmutation process could vary between 5 to 9% in SFR and 26 % in the case of ADS.

    The objective of this program is to provide the engineering tools necessary for an authoritative assessment of the performance of industrial furnaces firing pulverized coal. The program incorporates two experimental tasks and is constructed around an analytical task which will identify and upgrade the family of computer programs required to undertake the performance analysis studies. These analytical tools will be used to predict the effect of parameters such as fuel type and furnace variables on combustor performance, and to identify those properties which have a major impact on thermal performance. The second task uses a combustion reactor to screen the key variables identified and to provide data on the properties of coal particulate matter which affect heat transfer performance. Verification of the engineering analytical approach will be provided by measurements made in a pilot-scale furnace. This present report discusses technical progress during the first three months of the program, and considers the selection of the appropriate analytical tools and preliminary details of the experimental system.

    Before disposing of transuranic radioactive waste in the Waste Isolation Pilot Plant (WIPP), the United States Department of Energy (DOE) must evaluate compliance with applicable long-term regulations of the United States Environmental Protection Agency (EPA). Sandia National Laboratories is conducting iterative performance assessments (PAs) of the WIPP for the DOE to provide interim guidance while preparing for a final compliance evaluation. This volume, Volume 2, contains the technical basis for the 1992 PA. Specifically, it describes the conceptual basis for consequence modeling and the PA methodology, including the selection of scenarios for analysis, the determination of scenario probabilities, and the estimation of scenario consequences using a Monte Carlo technique and a linked system of computational models. Additional information about the 1992 PA is provided in other volumes. Volume I contains an overview of WIPP PA and results of a preliminary comparison with the long-term requirements of the EPA`s Environmental Protection Standards for Management and Disposal of Spent Nuclear Fuel, High-Level and Transuranic Radioactive Wastes (40 CFR 191, Subpart B). Volume 3 contains the reference data base and values for input parameters used in consequence and probability modeling. Volume 4 contains uncertainty and sensitivity analyses related to the preliminary comparison with 40 CFR 191B. Volume 5 contains uncertainty and sensitivity analyses of gas and brine migration for undisturbed performance. Finally, guidance derived from the entire 1992 PA is presented in Volume 6.

    Duplex ultrasound is an evolving technology that allows the assessment of volumetric blood flow in the carotid and vertebral arteries during a range of interventions along the spectrum of health and chronic disease. Duplex ultrasound can provide high-resolution diameter and velocity information in real-time and is noninvasive with minimal risks or contraindications. However, this ultrasound approach is a specialized technique requiring intensive training and stringent control of multiple complex settings; results are highly operator-dependent, and analysis approaches are inconsistent. Importantly, therefore, methodological differences can invalidate comparisons between different imaging modalities and studies; such methodological errors have potential to discredit study findings completely. The task of this review is to provide the first comprehensive, user-friendly technical guideline for the application of duplex ultrasound in measuring extracranial blood flow in human research. An update on recent developments in the use of edge-detection software for offline analysis is highlighted, and suggestions for future directions in this field are provided. These recommendations are presented in an attempt to standardize measurements across research groups and, hence, ultimately to improve the accuracy and reproducibility of measuring extracranial blood flow both within subjects and between groups.

    In many European countries, image quality for digital x-ray systems used in screening mammography is currently specified using a threshold-detail detectability method. This is a two-part study that proposes an alternative method based on calculated detectability for a model observer: the first part of the work presents a characterization of the systems. Eleven digital mammography systems were included in the study; four computed radiography (CR) systems, and a group of seven digital radiography (DR) detectors, composed of three amorphous selenium-based detectors, three caesium iodide scintillator systems and a silicon wafer-based photon counting system. The technical parameters assessed included the system response curve, detector uniformity error, pre-sampling modulation transfer function (MTF), normalized noise power spectrum (NNPS) and detective quantum efficiency (DQE). Approximate quantum noise limited exposure range was examined using a separation of noise sources based upon standard deviation. Noise separation showed that electronic noise was the dominant noise at low detector air kerma for three systems; the remaining systems showed quantum noise limited behaviour between 12.5 and 380 µGy. Greater variation in detector MTF was found for the DR group compared to the CR systems; MTF at 5 mm(-1) varied from 0.08 to 0.23 for the CR detectors against a range of 0.16-0.64 for the DR units. The needle CR detector had a higher MTF, lower NNPS and higher DQE at 5 mm(-1) than the powder CR phosphors. DQE at 5 mm(-1) ranged from 0.02 to 0.20 for the CR systems, while DQE at 5 mm(-1) for the DR group ranged from 0.04 to 0.41, indicating higher DQE for the DR detectors and needle CR system than for the powder CR phosphor systems. The technical evaluation section of the study showed that the digital mammography systems were well set up and exhibiting typical performance for the detector technology employed in the respective systems.

    The Ocean Thermal Energy Conversion (OTEC) Life Cycle Cost Assessment (OLCCA) is a study performed by members of the Lockheed Martin (LM) OTEC Team under funding from the Department of Energy (DOE), Award No. DE-EE0002663, dated 01/01/2010. OLCCA objectives are to estimate procurement, operations and maintenance, and overhaul costs for two types of OTEC plants: -Plants moored to the sea floor where the electricity produced by the OTEC plant is directly connected to the grid ashore via a marine power cable (Grid Connected OTEC plants) -Open-ocean grazing OTEC plant-ships producing an energy carrier that is transported to designated ports (Energy Carrier OTEC plants) Costs are developed using the concept of levelized cost of energy established by DOE for use in comparing electricity costs from various generating systems. One area of system costs that had not been developed in detail prior to this analysis was the operations and sustainment (O&S) cost for both types of OTEC plants. Procurement costs, generally referred to as capital expense and O&S costs (operations and maintenance (O&M) costs plus overhaul and replacement costs), are assessed over the 30 year operational life of the plants and an annual annuity calculated to achieve a levelized cost (constant across entire plant life). Dividing this levelized cost by the average annual energy production results in a levelized cost of electricity, or LCOE, for the OTEC plants. Technical and production efficiency enhancements that could result in a lower value of the OTEC LCOE were also explored. The thermal OTEC resource for Oahu, Hawaii and projected build out plan were developed. The estimate of the OTEC resource and LCOE values for the planned OTEC systems enable this information to be displayed as energy supplied versus levelized cost of the supplied energy; this curve is referred to as an Energy Supply Curve. The Oahu Energy Supply Curve represents initial OTEC deployment starting in 2018 and demonstrates the

    The Industrial Assessment Center (IAC) program at West Virginia University (WVU), which is funded by the Industrial Technologies Program (ITP) in the U.S. Department of Energy’s (DOE) Office of Energy Efficiency and Renewable Energy (EERE), has provided a unique opportunity to enhance efficient energy utilization in small to medium-sized manufacturers. It has also provided training to engineering students in the identification and analysis of efficient energy use in each aspect of the manufacturing process and associated supporting elements. The outcomes of the IAC Program at WVU have assisted the manufacturers and the students in having a heightened sensitivity to industrial energy conservation, waste reduction, and productivity improvement, as well as a better understanding of the technical aspects of manufacturing processes and the supporting elements through which efficient energy utilization can be enhanced. The IAC at WVU has conducted 101 energy assessments from 2002 until 2006. The focus of the industrial assessments has been on energy savings. It has been the IAC’s interest to strongly focus on energy savings and on waste minimization and productivity improvements that strictly have an impact on energy. The IAC at WVU was selected as the Center of the year in 2005 from amongst 26 centers and has obtained a ranking within the top 5 in the previous few years. From 2002 to 2006, the total recommended energy savings produced by the IAC at WVU is 1,214,414 MMBtu, of which the electricity accounts for 93,826,067 kWh (equivalent to 320,226 MMBtu) and natural gas for 871,743 MMBtu. The balance is accounted for in savings in other fuels, mainly coal and wood. This results in an average recommended energy savings of 928,971 kWh from electricity and 8,631 MMBtu from natural gas per facility. The total CO2 emissions saved from 2002 to 2006 is 154,462 tons, with an average of 1,529.3 tons per facility. The average recommended energy cost savings per facility is

    Advanced small modular reactors (aSMRs) can provide the United States with a safe, sustainable, and carbon-neutral energy source. The controllable day-to-day costs of aSMRs are expected to be dominated by operation and maintenance costs. Health and condition assessment coupled with online risk monitors can potentially enhance affordability of aSMRs through optimized operational planning and maintenance scheduling. Currently deployed risk monitors are an extension of probabilistic risk assessment (PRA). For complex engineered systems like nuclear power plants, PRA systematically combines event likelihoods and the probability of failure (POF) of key components, so that when combined with the magnitude of possible adverse consequences to determine risk. Traditional PRA uses population-based POF information to estimate the average plant risk over time. Currently, most nuclear power plants have a PRA that reflects the as-operated, as-modified plant; this model is updated periodically, typically once a year. Risk monitors expand on living PRA by incorporating changes in the day-by-day plant operation and configuration (e.g., changes in equipment availability, operating regime, environmental conditions). However, population-based POF (or population- and time-based POF) is still used to populate fault trees. Health monitoring techniques can be used to establish condition indicators and monitoring capabilities that indicate the component-specific POF at a desired point in time (or over a desired period), which can then be incorporated in the risk monitor to provide a more accurate estimate of the plant risk in different configurations. This is particularly important for active systems, structures, and components (SSCs) proposed for use in aSMR designs. These SSCs may differ significantly from those used in the operating fleet of light-water reactors (or even in LWR-based SMR designs). Additionally, the operating characteristics of aSMRs can present significantly different

    High-frequency continuous measurements of the partial pressure of CO2 (pCO2) are crucial for constraining the spatiotemporal dynamics of CO2 emissions from inland water systems. However, direct measurements of pCO2 are scarce, and no systematic comparisons have been conducted on the suitability of the widely used measurement systems for continuous underway or long-term deployment in various field conditions. We compared spray- and marble-type equilibrators and a membrane-enclosed CO2 sensor to assess their suitability for continuous long-term or underway pCO2 measurements in an urbanized river system in Korea. Both equilibrators had a shorter response time compared with the membrane-enclosed sensor, and could capture large spatial variations of pCO2 during a transect study along a highly urbanized river reach. The membrane-enclosed sensor based on passive equilibration provided comparable underway measurements along the river sections where pCO2 varied within the sensor detection range. When deployed in a eutrophic river site, the membrane-enclosed sensor was able to detect large diel variations in pCO2. However, biofouling on the membrane could reduce the accuracy of the measurement during long deployments exceeding several days. The overall results suggest that the fast response of the equilibrator systems facilitates capturing large spatial variations in pCO2 during short underway measurements. However, the attendant technical challenges of these systems, such as clogging and desiccant maintenance, have to be addressed carefully to enable their long-term deployment. The membrane-enclosed sensor would be suitable as an alternative tool for long-term continuous measurements if membrane biofouling could be overcome by appropriate antifouling measures such as copper mesh coverings.

    Lafave, Mark R.; Butterwick, Dale J.

    2014-01-01

    Context: Athletic taping skills are highly valued clinical competencies in the athletic therapy and training profession. The Technical Skill Assessment Instrument (TSAI) has been content validated and tested for intrarater reliability. Objective: To test the reliability of the TSAI using a more robust measure of reliability, generalizability theory, and to hypothetically and mathematically project the optimal number of raters and scenarios to reliably measure athletic taping skills in the future. Setting: Mount Royal University. Design: Observational study. Patients or Other Participants: A total of 29 university students (8 men, 21 women; age = 20.79 ± 1.59 years) from the Athletic Therapy Program at Mount Royal University. Intervention(s): Participants were allowed 10 minutes per scenario to complete prophylactic taping for a standardized patient presenting with (1) a 4-week-old second-degree ankle sprain and (2) a thumb that had been hyperextended. Two raters judged student performance using the TSAI. Main Outcome Measure(s): Generalizability coefficients were calculated using variance scores for raters, participants, and scenarios. A decision study was calculated to project the optimal number of raters and scenarios to achieve acceptable levels of reliability. Generalizability coefficients were interpreted the same as other reliability coefficients, with 0 indicating no reliability and 1.0 indicating perfect reliability. Results: The result of our study design (2 raters, 1 standardized patient, 2 scenarios) was a generalizability coefficient of 0.67. Decision study projects indicated that 4 scenarios were necessary to reliably measure athletic taping skills. Conclusions: We found moderate reliability coefficients. Researchers should include more scenarios to reliably measure athletic taping skills. They should also focus on the development of evidence-based practice guidelines and standards of athletic taping and should test those standards using a

    In recent years, the Mars One program has gained significant publicity for its plans to colonize the red planet. Beginning in 2025, the program plans to land four people on Mars every 26 months via a series of one-way missions, using exclusively existing technology. This one-way approach has frequently been cited as a key enabler of accelerating the first crewed landing on Mars. While the Mars One program has received considerable attention, little has been published in the technical literature regarding the formulation of its mission architecture. In light of this, we perform an independent analysis of the technical feasibility of the Mars One mission plan, focusing on the architecture of the life support and in-situ resource utilization (ISRU) systems, and their impact on sparing and space logistics. To perform this analysis, we adopt an iterative analysis approach in which we model and simulate the mission architecture, assess its feasibility, implement any applicable modifications while attempting to remain within the constraints set forth by Mars One, and then resimulate and reanalyze the revised version of the mission architecture. Where required information regarding the Mars One mission architecture is not available, we assume numerical values derived from standard spaceflight design handbooks and documents. Through four iterations of this process, our analysis finds that the Mars One mission plan, as publicly described, is not feasible. This conclusion is obtained from analyses based on mission assumptions derived from and constrained by statements made by Mars One, and is the result of the following findings: (1) several technologies including ISRU, life support, and entry, descent, and landing (EDL) are not currently "existing, validated and available" as claimed by Mars One; (2) the crop growth area described by Mars One is insufficient to feed their crew; (3) increasing the crop growth area to provide sufficient food for the crew leads to atmospheric

    Fourteen Tiger Team Assessment and eight Technical Safety Appraisal (TSA) final reports have been received and reviewed by the DOE Training Coordination Program during Fiscal Year 1992. These assessments and appraisals included both reactor and non-reactor nuclear facilities in their reports. The Tiger Team Assessments and TSA reports both used TSA performance objectives, and list ``concerns`` as a result of their findings. However, the TSA reports categorized concerns into the following functional areas: (1) Organization and Administration, (2) Radiation Protection, (3) Nuclear Criticality Safety, (4) Occupational Safety, (5) Engineering/Technical Support, (6) Emergency Preparedness, (7) Safety Assessments, (8) Quality Verification, (9) Fire Protection, (10) Environmental Protection, and (11) Energetic Materials Safety. Although these functional areas match most of the TSA performance objectives, not all of the TSA performance objectives are addressed. For example, the TSA reports did not include Training, Maintenance, and Operations as functional areas. Rather, they included concerns that related to these topics throughout the 11 functional areas identified above. For consistency, the Operations concerns that were identified in each of the TSA report functional areas have been included in this summary with the corresponding TSA performance objective.

    A SETAC Technical Workshop titled "The Nexus Between Ecological Risk Assessment and Natural Resource Damage Assessment Under CERCLA: Understanding and Improving the Common Scientific Underpinnings," was held 18-22 August 2008 in Gregson, Montana, USA, to examine the linkage, nexus, and overlap between ecological risk assessment (ERA) and natural resource damage assessment (NRDA) under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). Experts from a broad range of relevant scientific, legal, and policy disciplines convened to 1) ascertain the potential for improved scientific harmonization of the processes of ERA and NRDA; 2) identify where statutory, regulatory, or scientific constraints might exist that would constrain or preclude the harmonization of the 2 processes; 3) determine approaches that might overcome these constraints; and 4) recommend research or potential changes in regulatory policies that might serve to improve both processes. This is the introduction to a series of 3 papers that describe the findings and conclusions of this workshop. Although unanimity was not achieved on all technical, legal, or policy questions posed to the participants, some consensus areas did arise. First, there appear to be few if any legal constraints to using the environmental data collected for ERA or NRDA for both processes. Second, although it is important to recognize and preserve the distinctions between ERA and NRDA, opportunities for data sharing exist, particularly for the characterization of environmental exposures and derivation of ecotoxicological information. Thus, effective coordination is not precluded by the underlying science. Where a cooperative, interactive process is involved among the response agencies, the natural resource trustees, and the responsible party(s), technical, legal or regulatory constraints can be minimized. Finally, one approach that might enhance the potential applicability of data collected for the ERA

    The United States Department of Energy (DOE) commissioned a study the suitability of different advanced reactor concepts to support materials irradiations (i.e. a test reactor) or to demonstrate an advanced power plant/fuel cycle concept (demonstration reactor). As part of the study, an assessment of the technical maturity of the individual concepts was undertaken to see which, if any, can support near-term deployment. A Working Group composed of the authors of this document performed the maturity assessment using the Technical Readiness Levels as defined in DOE’s Technology Readiness Guide . One representative design was selected for assessment from of each of the six Generation-IV reactor types: gas-cooled fast reactor (GFR), lead-cooled fast reactor (LFR), molten salt reactor (MSR), supercritical water-cooled reactor (SCWR), sodium-cooled fast reactor (SFR), and very high temperature reactor (VHTR). Background information was obtained from previous detailed evaluations such as the Generation-IV Roadmap but other technical references were also used including consultations with concept proponents and subject matter experts. Outside of Generation IV activity in which the US is a party, non-U.S. experience or data sources were generally not factored into the evaluations as one cannot assume that this data is easily available or of sufficient quality to be used for licensing a US facility. The Working Group established the scope of the assessment (which systems and subsystems needed to be considered), adapted a specific technology readiness scale, and scored each system through discussions designed to achieve internal consistency across concepts. In general, the Working Group sought to determine which of the reactor options have sufficient maturity to serve either the test or demonstration reactor missions.

    This research was to evaluate the Technical Guideline (HJ/T130-2003) effectiveness based on data resource from a questionnaire survey and interviews on EIA experts. The result demonstrated that the guideline served mainly as a quality control measure for PEIA products, and only a small proportion of experts considered it effective due to its inconsistency with the newly released Chinese PEIA Regulation (2009) and poor practicability. Current status of SEA implementation in China was also studied in terms of application fields, effectiveness evaluation, and major issues to affect SEA, to conclude that SEA implementation in China is premature, and with limited effectiveness. The major problem was the lack of effective methodologies and technical tools. Recommendations for revising the PEIA Guideline and advices to improving SEA implementation in China were accordingly proposed.

    2016-01-01

    How much energy could be generated if PV modules were installed on all of the suitable roof area in the nation? To answer this question, we first use GIS methods to process a lidar dataset and determine the amount of roof area that is suitable for PV deployment in 128 cities nationwide, containing 23% of U.S. buildings, and provide PV-generation results for a subset of those cities. We then extend the insights from that analysis to the entire continental United States. We develop two statistical models--one for small buildings and one for medium and large buildings--and populate them with geographic variables that correlate with rooftop's suitability for PV. We simulate the productivity of PV installed on the suitable roof area, and present the technical potential of PV on both small buildings and medium/large buildings for every state in the continental US. Within the 128 cities covered by lidar data, 83% of small buildings have a location suitable for a PV installation, but only 26% of the total rooftop area of small buildings is suitable for development. The sheer number of buildings in this class, however, gives small buildings the greatest technical potential. Small building rooftops could accommodate 731 GW of PV capacity and generate 926 TWh/year of PV energy, approximately 65% of rooftop PV's total technical potential. We conclude by summing the PV-generation results for all building sizes and therefore answering our original question, estimating that the total national technical potential of rooftop PV is 1,118 GW of installed capacity and 1,432 TWh of annual energy generation. This equates to 39% of total national electric-sector sales.

    This technical report responds to the recognition by the U.S. Global Change Research Program (USGCRP) and the National Climate Assessment (NCA) of the importance of understanding how land use and land cover (LULC) affects weather and climate variability and change and how that variability and change affects LULC. Current published, peer-reviewed, scientific literature and supporting data from both existing and original sources forms the basis for this report's assessment of the current state of knowledge regarding land change and climate interactions. The synthesis presented herein documents how current and future land change may alter environment processes and in turn, how those conditions may affect both land cover and land use by specifically investigating, * The primary contemporary trends in land use and land cover, * The land-use and land-cover sectors and regions which are most affected by weather and climate variability,* How land-use practices are adapting to climate change, * How land-use and land-cover patterns and conditions are affecting weather and climate, and * The key elements of an ongoing Land Resources assessment. These findings present information that can be used to better assess land change and climate interactions in order to better assess land management and adaptation strategies for future environmental change and to assist in the development of a framework for an ongoing national assessment.

    This report provides an assessment of technical and production risks of candidate low-cost attitude/heading reference systems (AHRS) for use in the Advanced General Aviation Transport Experiments (AGATE) airplanes. A low-cost AHRS is a key component of modem "glass cockpit" flight displays for General Aviation (GA) aircraft. The technical capabilities of several candidate low-cost AHRS were examined and described along with the technical issues involved with using all solid-state components for attitude measurement. An economic model was developed which describes the expected profit, rate of return, and volume requirements for the manufacture of low-cost AHRS for GA aircraft in the 2000 to 2020 time frame. The model is the result of interviews with GA airframe manufacturers, avionics manufacturers and historical analysis of avionics of similar complexity. The model shows that a manufacturer will break even after three years of AHRS production, realizing an 18 percent rate of return (23 percent profit) on an investment of $3.5M over the 20 year period. A start-up production estimate showed costs of $6-12M for a new company to build and certify an AHRS from scratch, considered to be a high-risk proposition, versus $0.25-0.75M for an experienced avionics manufacturer to manufacture a design under license, a low-risk proposition.

    A couple of domestic institutions have been investigating the application of vitrification technology to treat low- and intermediate-level radioactive wastes in Korea. In the case that such investigations prove to be successful, it is expected that commercial vitrification plants will be constructed. The safety insuring on vitrification plants could not be compatible with criterion on radioactive waste management because the facilities are at high temperature and contain a variety of accommodations for the exhaust gases and residual products. Therefore, it is necessary to suggest a new strategy or modifications of criterion of radioactive waste management on considerations related with the vitrification technology. In order to ensure the safety of vitrification plants, a technical guideline or standard for design and operation of vitrification plants must be established too. A study on the safety assessment of vitrification plants in consideration with general items as an industrial facility, safety and technical requirements as a nuclear facility is needed to be ready before using and permitting them. Also, the stability of vitrified waste forms produced by vitrification plants must be analyzed to ensure their acceptance in final repositories, which includes chemical durability as one of the main considerable items. This paper introduces the status on the utilization of vitrification technology for treating LILW and efforts to develop technical guides with basic study results on chemical durability of forms.

  19. Assessment of the technical and economic feasibility of coal sludge slurries

    1999-07-01

    Over the past two decades, there has been considerable progress made in the technical developments relating to the utilization of coal in the form of a coal water slurry (CWS) both as a gasifier feedstock and as a furnace fuel. A very promising approach to utilizing CWS in an economical and cost effective manner is to use its basic technical advantage over coal, i.e. its behavior as a fluid as a method of introducing other ordinary unusable fuel sources such as sewage sludge or other solid Btu containing wastes. This can provide an economic advantage to CWS via waste disposal fees income as well as solving a vexing disposal problem. Sewage sludge presents severe disposal problems for municipalities across the country. The problem of sewage sludge disposal has reached crisis proportions in many areas of the country. Although the benefit of concentrating the sludge slurry for combustion is evident, there is a major technical barrier, which is related to the rheological properties of the sludge. It would appear that the solids in a sludge slurry consist of both colloidal-sized particles and larger open-structures which trap a significant amount of water. As the sludge is concentrated, it begins to lose its fluid properties at about 10% solids and becomes a filter cake at 15% solids which must be handled as a solid, i.e. belt feeders, etc. This poses problems for incineration because feeding concentrated sludge requires mechanical feeders and combustion of the sludge requires a considerable amount of excess air (40--50%) and significant quantities of auxiliary fuels. Direct combustion of sludge in a resource recovery facility or an incinerator also leads to high levels of uncontrolled emissions including particulates and metals such as cadmium, mercury, etc. Expensive emission controls are required to meet EPA limits. The net result is a considerable add-on expense to sludge disposal with little recovery of the inherent Btu value. The overall goal of this project was

    Western Research Institute, in conjunction with the Electric Power Research Institute, Foster Wheeler International, Inc. and the US Department of Energy, has undertaken a research and demonstration program designed to examine the market potential and the technical feasibility of ash use options for PFBC ashes. Ashes from the Foster Wheeler Energia Oy pilot-scale circulating PFBC tests in Karhula, Finland, combusting (1) low-sulfur subbituminous and (2) high-sulfur bituminous coal, and ash from the AEP's high-sulfur bituminous coal-fired bubbling PFBC in Brilliant, Ohio, were evaluated in laboratory and pilot-scale ash use testing at WR1. The technical feasibility study examined the use of PFBC ash in construction-related applications, including its use as a cementing material in concrete and use in cement manufacturing, fill and embankment materials, soil stabilization agent, and use in synthetic aggregate production. Testing was also conducted to determine the technical feasibility of PFBC ash as a soil amendment for acidic and sodic problem soils and spoils encountered in agricultural and reclamation applications. The results of the technical feasibility testing indicated the following conclusions. PFBC ash does not meet the chemical requirements as a pozzolan for cement replacement. However, it does appear that potential may exist for its use in cement production as a pozzolan and/or as a set retardant. PFBC ash shows relatively high strength development, low expansion, and low permeability properties that make its use in fills and embankments promising. Testing has also indicated that PFBC ash, when mixed with low amounts of lime, develops high strengths, suitable for soil stabilization applications and synthetic aggregate production. Synthetic aggregate produced from PFBC ash is capable of meeting ASTM/AASHTO specifications for many construction applications. The residual calcium carbonate and calcium sulfate in the PFE3C ash has been shown to be of value in

    2007-07-01

    The technical properties of three layered cement-bonded boards (CBBs) made from wastepaper and sawdust were investigated. The CBBs were produced at three density levels of 1000, 1200 and 1300 kg/m{sup 3} and at four cement/particle ratios of 2.0:1, 2.5:1, 3.0:1 and 3.5:1 on a weight to weight basis. The technical properties evaluated were modulus of rupture (MOR), modulus of elasticity (MOE), water absorption (WA) and thickness swelling (TS). The MOR values ranged from 4.85 to 11.69 MPa and MOE values ranged from 2.80 to 5.57 GPa. The mean values of WA and TS after 24 h of water soaking of the CBBs ranged from 18.18% to 40.49% and 3.55% to 12.13%, respectively. MOR and MOE of the CBBs increased with increase in board density, but MOR decreased with the increase in cement/particle ratio. On the other hand, WA and TS decreased with increase in board density and cement/particle ratio. CBBs produced from wastepaper and sawdust at cement/particle ratios of 3.0:1 and 3.5:1 are suitable for building construction such as paneling, ceiling and partitioning.

  18. Exploring genome wide bisulfite sequencing for DNA methylation analysis in livestock: a technical assessment.

    PubMed

    Doherty, Rachael; Couldrey, Christine

    2014-01-01

    Recent advances made in "omics" technologies are contributing to a revolution in livestock selection and breeding practices. Epigenetic mechanisms, including DNA methylation are important determinants for the control of gene expression in mammals. DNA methylation research will help our understanding of how environmental factors contribute to phenotypic variation of complex production and health traits. High-throughput sequencing is a vital tool for the comprehensive analysis of DNA methylation, and bisulfite-based strategies coupled with DNA sequencing allows for quantitative, site-specific methylation analysis at the genome level or genome wide. Reduced representation bisulfite sequencing (RRBS) and more recently whole genome bisulfite sequencing (WGBS) have proven to be effective techniques for studying DNA methylation in both humans and mice. Here we report the development of RRBS and WGBS for use in sheep, the first application of this technology in livestock species. Important technical issues associated with these methodologies including fragment size selection and sequence depth are examined and discussed. PMID:24860595

    Toxicogenomics promises to be an important part of future human health risk assessment of environmental chemicals. The application of gene expression profiles (e.g., for hazard identification, chemical prioritization, chemical grouping, mode of action discovery, and quantitative analysis of response) is growing in the literature, but their use in formal risk assessment by regulatory agencies is relatively infrequent. Although additional validations for specific applications are required, gene expression data can be of immediate use for increasing confidence in chemical evaluations. We believe that a primary reason for the current lack of integration is the limited practical guidance available for risk assessment specialists with limited experience in genomics. The present manuscript provides basic information on gene expression profiling, along with guidance on evaluating the quality of genomic experiments and data, and interpretation of results presented in the form of heat maps, pathway analyses and other common approaches. Moreover, potential ways to integrate information from gene expression experiments into current risk assessment are presented using published studies as examples. The primary objective of this work is to facilitate integration of gene expression data into human health risk assessments of environmental chemicals. PMID:25944780

    2006-01-01

    Using a geology-based assessment methodology, the U.S. Geological Survey - Afghanistan Ministry of Mines and Industry Joint Oil and Gas Resource Assessment Team estimated mean volumes of undiscovered petroleum in northern Afghanistan; the resulting estimates are 1.6 billion barrels (0.2 billion metric tons) of crude oil, 16 trillion cubic feet (0.4 trillion cubic meters) of natural gas, and 0.5 billion barrels (0.8 billion metric tons) of natural gas liquids. Most of the undiscovered crude oil is in the Afghan-Tajik Basin and most of the undiscovered natural gas is in the Amu Darya Basin. Four total petroleum systems were identified, and these were subdivided into eight assessment units for the purpose of this resource assessment. The area with the greatest potential for undiscovered natural gas accumulations is in Upper Jurassic carbonate and reef reservoirs beneath an impermeable salt layer in relatively unexplored parts of northern Afghanistan. The Afghan-Tajik Basin has the greatest potential for undiscovered crude oil accumulations, and these are potentially in Cretaceous to Paleogene carbonate reservoir rocks associated with thrust faulting and folding.

    2008-01-01

    The U.S. Geological Survey (USGS) has completed an assessment of the undiscovered oil and associated gas resources of the Upper Devonian to Lower Mississippian Bakken Formation in the U.S. portion of the Williston Basin of Montana and North Dakota and within the Williston Basin Province. The assessment is based on geologic elements of a total petroleum system (TPS), which include (1) source-rock distribution, thickness, organic richness, maturation, petroleum generation, and migration; (2) reservoir-rock type (conventional or continuous), distribution, and quality; and (3) character of traps and time of formation with respect to petroleum generation and migration. Framework studies in stratigraphy and structural geology and modeling of petroleum geochemistry, combined with historical exploration and production analyses, were used to estimate the undiscovered, technically recoverable oil resource of the Bakken Formation. Using this framework, the USGS defined a Bakken-Lodgepole TPS and seven assessment units (AU) within the system. For the Bakken Formation, the undiscovered oil and associated gas resources were quantitatively estimated for six of these AUs.

    1987-11-01

    A preliminary assessment of the technical and economic feasibility of a district heating and cooling (DHC) system serving a portion of Joliet, Illinois, has been completed. The basic system, which was designed to provide thermal and electrical energy services to the assessment area, was found to be economically feasible while providing energy services at prices that are less than or equal to current costs. The DHC assessment area included the following: the Downtown Business District; the newly-designated Heritage Business Park; and the Joliet Correctional Center. The Heritage Business Park is the site of a former steel wire and rod mill. Approximately one-third of the site is currently occupied by a rod mill operated by American Steel and Wire while the rest of the Park is essentially undeveloped. In late 1985, plans were formulated to redevelop the site into an industrial park for light industry, offices and research and development facilities. The installation of a DHC system over the next five to ten years would not only complement the redevelopment of the Downtown Business District that was recently begun, but would help to encourage the eventual development of the Heritage Business Park as well.

  16. Technical Note: Seasonality in alpine water resources management - a regional assessment

    NASA Astrophysics Data System (ADS)

    Vanham, D.; Fleischhacker, E.; Rauch, W.

    2008-01-01

    Alpine regions are particularly affected by seasonal variations in water demand and water availability. Especially the winter period is critical from an operational point of view, as being characterised by high water demands due to tourism and low water availability due to the temporal storage of precipitation as snow and ice. The clear definition of summer and winter periods is thus an essential prerequisite for water resource management in alpine regions. This paper presents a GIS-based multi criteria method to determine the winter season. A snow cover duration dataset serves as basis for this analysis. Different water demand stakeholders, the alpine hydrology and the present day water supply infrastructure are taken into account. Technical snow-making and (winter) tourism were identified as the two major seasonal water demand stakeholders in the study area, which is the Kitzbueheler region in the Austrian Alps. Based upon different geographical datasets winter was defined as the period from December to March, and summer as the period from April to November. By determining potential regional water balance deficits or surpluses in the present day situation and in future, important management decisions such as water storage and allocation can be made and transposed to the local level.

    2014-01-01

    Since the early 1950s, the number of international measurement standards for anchoring stable isotope delta scales has mushroomed from 3 to more than 30, expanding to more than 25 chemical elements. With the development of new instrumentation, along with new and improved measurement procedures for studying naturally occurring isotopic abundance variations in natural and technical samples, the number of internationally distributed, secondary isotopic reference materials with a specified delta value has blossomed in the last six decades to more than 150 materials. More than half of these isotopic reference materials were produced for isotope-delta measurements of seven elements: H, Li, B, C, N, O, and S. The number of isotopic reference materials for other, heavier elements has grown considerably over the last decade. Nevertheless, even primary international measurement standards for isotope-delta measurements are still needed for some elements, including Mg, Fe, Te, Sb, Mo, and Ge. It is recommended that authors publish the delta values of internationally distributed, secondary isotopic reference materials that were used for anchoring their measurement results to the respective primary stable isotope scale.

    The objective of the study is to evaluate the technical and economic feasibility of producing motor fuel grade (MFG) ethanol in smaller plants amenable to a farm or cooperative operation. Several parameters are explored as follows: six agricultural locations; three plant sizes of 90,000, 300,000, and 900,000 gallons per year; five feedstocks; ethanol proof levels of 190 and 199; and byproduct distillers grains either as whole stillage or prepared by various degrees of drying. Plants were assumed to operate only 6000 hours per year (sugar beets only 3600 hours) because of limitations of time (or beet feedstock). Locally available boiler fuels were chosen. Simplified processing was identified so as to be realistically within the time and experience available to a farmer-operator. The most attractive case used Indiana corn in a 900,000 gallon plant making 190 proof ethanol, and selling whole stillage (no dewatering or drying). Plant investment for this best case as well as several option combinations is given. The selling price of the best case 190 proof ethanol at 20% IROR was $1.79 based on $2.70 corn.

  20. Method of machine technical state assessment on the basis of joint signal analysis

    NASA Astrophysics Data System (ADS)

    Fidali, Marek

    2011-04-01

    Joint analysis of two signals which are observed during machine operation allows us to acquire information on such phenomena occurring within the machine which cannot be obtained as the results of an analysis of single signals. This knowledge makes it purposeful to assume that the joint analysis of a major number of signals allows us also to acquire new information on the machine state. In this paper the concept of joint signal analysis based on a signal analysis in both "micro" and "macro" time domains was described. In order to calculate values of joint features of signals and determine the machine state on the basis of the joint analysis results the generalized data window was introduced. In order to limit a number of simultaneously considered signals and determine a relation between signal feature values and machine states, the procedure based on an application of additional virtual signals was proposed. In order to verify the elaborated method an active diagnostic experiment was carried out. The experiment result was a set of learning data, which enables us to construct a diagnostic classifier. Exemplary results of classification of technical state of a machine were also presented.

    This report presents the preclosure performance assessment review (PAR) of the Site Characterization Plan Conceptual Design Report (SCP-CDR). The PAR was performed on the design presented in the SCP-CDR working draft, Revision 1, released in October 1986. After review this working draft became the ''Site Characterization Plan Conceptual Design Report'', Revision 1. There are two distinct objectives of the PAR: (1) to analyze the design presented in the SCP-CDR in terms of offsite and occupational radiological safety, and (2) to test safety assessment methods and tools. This report addresses only the first of the PAR objectives. The PAR analysis consists of assessments of offsite and occupational doses resulting from routine and abnormal repository events. The scope of the analysis is restricted to preclosure operations at the repository. This report addresses (1) the description of repository facilities and operations, (2) the development of radioactive material inventories and radiation dose rates, (3) the development of radioactive material release scenarios and source terms, and (4) the assessment of offsite and occupational radiation dose equivalents. This report contains a summary of the analyses in the above four areas, and analysis details are documented. The results of the assessments are compared with regulatory requirements to determine how the repository performs relative to the requirements. The analyses indicate that the offsite and occupational impacts comply with regulatory requirements. However, based on this preliminary analysis of the draft design document, the occupational impacts exceed the SCP-CDR design objective of 1 rem/year in some areas. 59 refs., 12 figs., 127 tabs.

  2. Technical note on probabilistic assessment of one-step-ahead rainfall variation by Split Markov Process

    Maity, R.; Prasad, D.

    2011-01-01

    In this paper, Split Markov Process (SMP) is developed to assess one-step-ahead variation of daily rainfall at a rain gauge station. SMP is an advancement of general Markov Process (MP) and specially developed for probabilistic assessment of change in daily rainfall magnitude. The approach is based on a first-order Markov chain to simulate daily rainfall variation at a point through state/sub-state Transitional Probability Matrix (TPM). The state/sub-state TPM is based on the historical transitions from a particular state to a particular sub-state, which is the basic difference between SMP and general MP. In MP, the transition from a particular state to another state is investigated. However, in SMP, the daily rainfall magnitude is categorized into different states and change in magnitude from one temporal step to another is categorized into different sub-states for the probabilistic assessment of rainfall variation. The cumulative state/sub-state TPM is represented in a contour plot at different probability levels. The developed cumulative state/sub-state TPM is used to assess the possible range of rainfall in next time step, in a probabilistic sense. Application of SMP is investigated for daily rainfall at Khandwa station in the Nimar district of Madhya Pradesh, India. Eighty years of daily monsoon rainfall is used to develop the state/sub-state TPM and twenty years data is used to investigate its performance. It is observed that the predicted range of daily rainfall captures the actual observed rainfall with few exceptions. Overall, the assessed range, particularly the upper limit, provides a quantification possible extreme value in the next time step, which is very useful information to tackle the extreme events, such flooding, water logging etc.

  3. Defining the “proven technology” technical criterion in the reactor technology assessment for Malaysia’s nuclear power program

    Developing countries that are considering the deployment of nuclear power plants (NPPs) in the near future need to perform reactor technology assessment (RTA) in order to select the most suitable reactor design. The International Atomic Energy Agency (IAEA) reported in the Common User Considerations (CUC) document that “proven technology” is one of the most important technical criteria for newcomer countries in performing the RTA. The qualitative description of five desired features for “proven technology” is relatively broad and only provides a general guideline to its characterization. This paper proposes a methodology to define the “proven technology” term according to a specific country’s requirements using a three-stage evaluation process. The first evaluation stage screens the available technologies in the market against a predefined minimum Technology Readiness Level (TRL) derived as a condition based on national needs and policy objectives. The result is a list of technology options, which are then assessed in the second evaluation stage against quantitative definitions of CUC desired features for proven technology. The potential technology candidates produced from this evaluation is further narrowed down to obtain a list of proven technology candidates by assessing them against selected risk criteria and the established maximum allowable total score using a scoring matrix. The outcome of this methodology is the proven technology candidates selected using an accurate definition of “proven technology” that fulfills the policy objectives, national needs and risk, and country-specific CUC desired features of the country that performs this assessment. A simplified assessment for Malaysia is carried out to demonstrate and suggest the use of the proposed methodology. In this exercise, ABWR, AP1000, APR1400 and EPR designs assumed the top-ranks of proven technology candidates according to Malaysia’s definition of “proven technology”.

    The Proliferation Path Assessment and Targeting System (PPATS) provides a common framework for conducting counterproliferation analysis. PPATS displays a network of acquisition pathways for nuclear, chemical and biological (NBC) weapons of mass destruction (WMD). The network display can be expanded to reveal individual process steps involving activities, equipment and materials. The PPATS software allows its users to link intelligence to the process steps, ascertain evidence of activity at certain steps and associate active steps installations/facilities. It allows analysts to determine critical paths based on findings of activity underway and assess the impact of potential options imposed against the proliferant country or actor. This report provides a general description of the prototype of software development effort and its status within the counterproliferation community.

    The U.S. Department of Energy (DOE), Office of Environmental Management (EM) has responsibility for cleanup and disposition of nuclear wastes and excess materials that are a legacy of the nuclear arms race. In fulfilling this responsibility, EM applies a systems engineering approach to identify baseline disposition plans for the wastes and materials (storage, stabilization, treatment, and disposal), assess the path viability, and develop integration opportunities to improve the disposition viability or to combine, eliminate, and/or simplify activities, technologies, and facilities across the DOE Complex, evaluate the baseline and alternatives to make informed decisions, and implement and track selected opportunities. This paper focuses on processes used to assess the disposition path viability - the likelihood that current planning for disposition of nuclear waste and materials can be implemented.

    2013-01-01

    Several strategies for the effective separation of 99mTc from 99Mo have been developed and validated. Due to the success of column chromatographic separation using acidic alumina coupled with high specific activity fission 99Mo (F 99Mo) for production of 99Mo/99mTc generators, however, most technologies until recently have generated little interest. The reduced availability of F 99Mo and consequently the shortage of 99Mo/99mTc column generators in the recent past have resurrected interest in the production of 99Mo as well as 99mTc by alternate routes. Most of these alternative production processes require separation techniques capable of providing clinical grade 99mTc from low specific activity 99Mo or irradiated Mo targets. For this reason there has been renewed interest in alternate separation routes. This paper reviews the reported separation technologies which include column chromatography, solvent extraction, sublimation and gel systems that have been traditionally used for the fabrication of 99Mo/99mTc generator systems. The comparative advantage, disadvantage, and technical challenges toward adapting the emerging requirements are discussed. New developments such as solid-phase column extraction, electrochemical separation, extraction chromatography, supported liquid membrane (SLM) and thermochromatographic techniques are also being evaluated for their potential application in the changed scenario of providing 99mTc from alternate routes. Based on the analysis provided in this review, it appears that some proven separation technologies can be quickly resurrected for the separation of clinical grade 99mTc from macroscopic levels of reactor or cyclotron irradiated molybdenum targets. Furthermore, emerging technologies can be developed further to respond to the expected changing modes of 99mTc production.

  9. Weeks Island brine diffuser site study: baseline conditions and environmental assessment technical report

    SciTech Connect

    1980-12-12

    This technical report presents the results of a study conducted at two alternative brine diffuser sites (A and B) proposed for the Weeks Island salt dome, together with an analysis of the potential physical, chemical, and biological effects of brine disposal for this area of the Gulf of Mexico. Brine would result from either the leaching of salt domes to form or enlarge oil storage caverns, or the subsequent use of these caverns for crude oil storage in the Strategic Petroleum Reserve (SPR) program. Brine leached from the Weeks Island salt dome would be transported through a pipeline which would extend from the salt dome either 27 nautical miles (32 statute miles) for Site A, or 41 nautical miles (47 statute miles) for Site B, into Gulf waters. The brine would be discharged at these sites through an offshore diffuser at a sustained peak rate of 39 ft/sup 3//sec. The disposal of large quantities of brine in the Gulf could have a significant impact on the biology and water quality of the area. Physical and chemical measurements of the marine environment at Sites A and B were taken between September 1977 and July 1978 to correlate the existing environmental conditions with the estimated physical extent of tthe brine discharge as predicted by the MIT model (US Dept. of Commerce, 1977a). Measurements of wind, tide, waves, currents, and stratification (water column structure) were also obtained since the diffusion and dispersion of the brine plume are a function of the local circulation regime. These data were used to calculate both near- and far-field concentrations of brine, and may also be used in the design criteria for diffuser port configuration and verification of the plume model. Biological samples were taken to characterize the sites and to predict potential areas of impact with regard to the discharge. This sampling focused on benthic organisms and demersal fish. (DMC)

    Aim To evaluate a combined protocol for simultaneous cardiac MRI (CMR) and contrast-enhanced (CE) whole-body MR angiography (WB-MRA) techniques within a single examination. Materials and methods Asymptomatic volunteers (n = 48) with low-moderate risk of cardiovascular disease (CVD) were recruited. The protocol was divided into four sections: (1) CMR of left ventricle (LV) structure and function; (2) CE-MRA of the head, neck, and thorax followed by the distal lower limbs; (3) CMR LV “late gadolinium enhancement” assessment; and (4) CE-MRA of the abdomen and pelvis followed by the proximal lower limbs. Multiple observers undertook the image analysis. Results For CMR, the mean ejection fraction (EF) was 67.3 ± 4.8% and mean left ventricular mass (LVM) was 100.3 ± 22.8 g. The intra-observer repeatability for EF ranged from 2.1–4.7% and from 9–12 g for LVM. Interobserver repeatability was 8.1% for EF and 19.1 g for LVM. No LV delayed myocardial enhancement was observed. For WB-MRA, some degree of luminal narrowing or stenosis was seen at 3.6% of the vessel segments (involving n = 29 of 48 volunteers) and interobserver radiological opinion was consistent in 96.7% of 1488 vessel segments assessed. Conclusion Combined assessment of WB-MRA and CMR can be undertaken within a single examination on a clinical MRI system. The associated analysis techniques are repeatable and may be suitable for larger-scale cardiovascular MRI studies. PMID:25791202

    Hasler, William L.

    2011-01-01

    The wireless motility/pH capsule (WMC) is an orally ingested, nondigestible, data recording device that enables the simultaneous assessment of regional and whole gut transit. Approved by the US Food and Drug Administration for the evaluation of patients with suspected delayed gastric emptying and the evaluation of colonic transit time in patients with chronic idiopathic constipation, this capsule continuously measures the temperature, pH, and pressure of its surrounding environment while traveling through the gastrointestinal tract (via gut peristalsis) until exiting the body through the anus. Validated patterns in pH and temperature recordings allow for accurate measurement of gastric emptying, small bowel transit, colonic transit, and whole gut transit times. The WMC is a nonradioactive, office-based, gastrointestinal transit testing modality shown in several clinical trials to be a suitable alternative to scintigraphy and radiopaque marker studies in measuring gastric emptying, small bowel, colonic, and whole gut transit times. Unlike widely available transit tests, which provide only region-specific transit data, the WMC offers the benefit of measuring gastric, small bowel, and colonic transit times in a single examination. The WMC also provides intraluminal pressure readings throughout the digestive tract, offering a noninvasive means by which to assess gastrointestinal motility. The WMC should be considered the transit study of choice for individuals suspected of having altered transit in more than one region of the gastrointestinal tract. This review summarizes the features and performance characteristics of the WMC as well as provides a summary on how this diagnostic modality is most effectively used in the assessment of gastrointestinal symptom complexes due to suspected abnormalities in transit.

    Subsequent to preliminary investigations by the Golden Gate Bridge Highway & Transportation District (GGB), in coordination with Pacific Gas & Electric (PG&E), the GATEWAY Demonstration program was asked to evaluate the technical feasibility of replacing existing roadway lighting on the bridge with products utilizing LED technology. GGB and PG&E also indicated interest in induction (i.e., electrodeless fluorescent) technology, since both light source types feature rated lifetimes significantly exceeding those of the existing high-pressure sodium (HPS) and low-pressure sodium (LPS) products. The goal of the study was to identify any solutions which would reduce energy use and maintenance without compromising the quantity or quality of existing illumination. Products used for roadway lighting on the historic bridge must be installed within the existing amber-lensed shoebox-style luminaire housings. It was determined that induction technology does not appear to represent a viable alternative for the roadway luminaires in this application; any energy savings would be attributable to a reduction in light levels. Although no suitable LED retrofit kits were identified for installation within existing luminaire housings, several complete LED luminaires were found to offer energy savings of 6-18%, suggesting custom LED retrofit kits could be developed to match or exceed the performance of the existing shoeboxes. Luminaires utilizing ceramic metal halide (CMH) were also evaluated, and some were found to offer 28% energy savings, but these products might actually increase maintenance due to the shorter rated lamp life. Plasma technology was evaluated, as well, but no suitable products were identified. Analysis provided in this report was completed in May 2012. Although LED technologies are expected to become increasingly viable over time, and product mock-ups may reveal near-term solutions, some options not currently considered by GGB may ultimately merit evaluation.

    The threat from biological weapons is assessed through both a comparative historical analysis of the patterns of biological weapons use and an assessment of the technological hurdles to proliferation and use that must be overcome. The history of biological weapons is studied to learn how agents have been acquired and what types of states and substate actors have used agents. Substate actors have generally been more willing than states to use pathogens and toxins and they have focused on those agents that are more readily available. There has been an increasing trend of bioterrorism incidents over the past century, but states and substate actors have struggled with one or more of the necessary technological steps. These steps include acquisition of a suitable agent, production of an appropriate quantity and form, and effective deployment. The technological hurdles associated with the steps present a real barrier to producing a high consequence event. However, the ever increasing technological sophistication of society continually lowers the barriers, resulting in a low but increasing probability of a high consequence bioterrorism event.

    The performance and cost of compressed hydrogen storage tank systems has been assessed and compared to the U.S. Department of Energy (DOE) 2010, 2015, and ultimate targets for automotive applications. The on-board performance and high-volume manufacturing cost were determined for compressed hydrogen tanks with design pressures of 350 bar ({approx}5000 psi) and 700 bar ({approx}10,000 psi) capable of storing 5.6 kg of usable hydrogen. The off-board performance and cost of delivering compressed hydrogen was determined for hydrogen produced by central steam methane reforming (SMR). The main conclusions of the assessment are that the 350-bar compressed storage system has the potential to meet the 2010 and 2015 targets for system gravimetric capacity but will not likely meet any of the system targets for volumetric capacity or cost, given our base case assumptions. The 700-bar compressed storage system has the potential to meet only the 2010 target for system gravimetric capacity and is not likely to meet any of the system targets for volumetric capacity or cost, despite the fact that its volumetric capacity is much higher than that of the 350-bar system. Both the 350-bar and 700-bar systems come close to meeting the Well-to-Tank (WTT) efficiency target, but fall short by about 5%.

  1. Nuclear fuel cycle assessment of India: A technical study for U.S.-India cooperation

    NASA Astrophysics Data System (ADS)

    Krishna, Taraknath Woddi Venkat

    The recent civil nuclear cooperation proposed by the Bush Administration and the Government of India has heightened the necessity of assessing India's nuclear fuel cycle inclusive of nuclear materials and facilities. This agreement proposes to change the long-standing U.S. policy of preventing the spread of nuclear weapons by denying nuclear technology transfer to non-NPT signatory states. The nuclear tests in 1998 have convinced the world community that India would never relinquish its nuclear arsenal. This has driven the desire to engage India through civilian nuclear cooperation. The cornerstone of any civilian nuclear technological support necessitates the separation of military and civilian facilities. A complete nuclear fuel cycle assessment of India emphasizes the entwinment of the military and civilian facilities and would aid in moving forward with the separation plan. To estimate the existing uranium reserves in India, a complete historical assessment of ore production, conversion, and processing capabilities was performed using open source information and compared to independent reports. Nuclear energy and plutonium production (reactor- and weapons-grade) was simulated using declared capacity factors and modern simulation tools. The three-stage nuclear power program entities and all the components of civilian and military significance were assembled into a flowsheet to allow for a macroscopic vision of the Indian fuel cycle. A detailed view of the nuclear fuel cycle opens avenues for technological collaboration. The fuel cycle that grows from this study exploits domestic thorium reserves with advanced international technology and optimized for the existing system. To utilize any appreciable fraction of the world's supply of thorium, nuclear breeding is necessary. The two known possibilities for production of more fissionable material in the reactor than is consumed as fuel are fast breeders or thermal breeders. This dissertation analyzes a thermal

    Specialized Vertum Partners software tools were prototyped, tested and commercialized to allow wind energy stakeholders to assess the uncertainties of climate change on wind power production and distribution. This project resulted in three commercially proven products and a marketing tool. The first was a Weather Research and Forecasting Model (WRF) based resource evaluation system. The second was a web-based service providing global 10m wind data from multiple sources to wind industry subscription customers. The third product addressed the needs of our utility clients looking at climate change effects on electricity distribution. For this we collaborated on the Santa Ana Wildfire Threat Index (SAWTi), which was released publicly last quarter. Finally to promote these products and educate potential users we released “Gust or Bust”, a graphic-novel styled marketing publication.

    The radiation dose commitment to ten body organs/parts, due to inhalation of resuspended nuclear contaminants from target ships exposed to the underwater burst (Test Baker) is determined for personnel who worked on the ships during and after Operation CROSSROADS. Four representative ships, INDEPENDENCE, NEW YORK, PENSACOLA and SALT LAKE CITY, are examined for the personnel activities associated with post-BAKER reboarding. Additionally, the dose due to internal emitters is assessed for personnel who unloaded ammunition from twenty target ships at Kwajalein, and for shipyard workers exposed to eight of the higher intensity ships at Pearl Harbor, Puget Sound, and San Francisco Naval Shipyards. For almost all activities, fifty-year bone dose commitments are less than 0.15 rem from any annual period of exposure.

    On-board and off-board performance and cost of cryo-compressed hydrogen storage has been assessed and compared to the DOE 2010, 2015 and ultimate targets for automotive applications. The Gen-3 prototype system of Lawrence Livermore National Laboratory was modeled to project the performance of a scaled-down 5.6-kg usable hydrogen storage system. The on-board performance of the system and high-volume manufacturing cost were determined for liquid hydrogen refueling with a single-flow nozzle and a pump that delivers 1.5 kg/min of liquid H{sub 2} to the insulated cryogenic tank capable of being pressurized to 272 atm (4000 psi). The off-board performance and cost of delivering liquid hydrogen were determined for two scenarios in which hydrogen is produced by central steam methane reforming (SMR) and by central electrolysis using electricity from renewable sources. The main conclusions from the assessment are that the cryo-compressed storage system has the potential of meeting the ultimate target for system gravimetric capacity and the 2015 target for system volumetric capacity (see Table I). The system compares favorably with targets for durability and operability although additional work is needed to understand failure modes for combined pressure and temperature cycling. The system may meet the targets for hydrogen loss during dormancy under certain conditions of minimum daily driving. The high-volume manufacturing cost is projected to be 2-4 times the current 2010 target of $4/kWh. For the reference conditions considered most applicable, the fuel cost for the SMR hydrogen production and liquid H{sub 2} delivery scenario is 60%-140% higher than the current target of $2-$3/gge while the well-to-tank efficiency is well short of the 60% target specified for off-board regenerable materials.

    The study, Energy Vulnerability Assessment of the US Pacific Islands, was mandated by the Congress of the United States as stated in House Resolution 776-220 of 1992, Section 1406. The resolution states that the US Secretary of Energy shall conduct a study of the implications of the unique vulnerabilities of the insular areas to an oil supply disruption. Such study shall outline how the insular areas shall gain access to vital oil supplies during times of national emergency. The resolution defines insular areas as the US Virgin Islands, Puerto Rico, Guam, American Samoa, the Commonwealth of the Northern Mariana Islands, and Palau. The US Virgin Islands and Puerto Rico are not included in this report. The US Department of Energy (USDOE) has broadened the scope of the study contained in the House Resolution to include emergency preparedness and response strategies which would reduce vulnerability to an oil supply disruption as well as steps to ameliorate adverse economic consequences. This includes a review of alternative energy technologies with respect to their potential for reducing dependence on imported petroleum. USDOE has outlined the four tasks of the energy vulnerability assessment as the following: (1) for each island, determine crude oil and refined product demand/supply, and characterize energy and economic infrastructure; (2) forecast global and regional oil trade flow patterns, energy demand/supply, and economic activities; (3) formulate oil supply disruption scenarios and ascertain the general and unique vulnerabilities of these islands to oil supply disruptions; and (4) outline emergency preparedness and response options to secure oil supplies in the short run, and reduce dependence on imported oil in the longer term.

    An energy storage system which could be attractive for future electric utility peak-load applications is a modified gas turbine power system utilizing underground storage of very high pressure air. The compressed air energy storage (CAES) concept involves using off-peak electricity generated from indigenous coal or nuclear sources to compress air, storing the air in large underground facilities, and withdrawing the air during peak-load periods when it would be heated by combustion and expanded through gas turbines to generate power. The attractiveness of the CAES concept is based upon its potential to supply competitively priced peaking energy, to reduce peak-load power plant dependence on petroleum-based fuels, and to provide a means for leveling the utility system load demand. Therefore, a technical and economic assessment of coal-fired fluidized bed (FBC) combustor/compressed air energy storage (FBC/CAES) systems was performed and is described. The conclusions drawn from the FBC/CAES study program are encouraging. They indicate that pressurized FBC/CAES power plants should be technologically feasible, provide good performance, and be economically competitive. Specifically, it is concluded that: coal-fired FBC/CAES systems should be technically feasible in the near future and potentially attractive for peak-load power generation; and an open-bed PFBC/CAES configuration would provide the best candidate for early commercialization. It has relatively low risk combined with moderate cost and reasonable round-trip heat rate. It also has the potential for future growth options which tend to reduce costs and lower fuel consumption.

    Information is presented which was extracted from various assessments of energy storage technologies conducted during the past four years, primarily under the auspices of the Office of Energy Systems Research and Development (formerly the Division of Energy Storage Systems). A thorough search of the relevant literature was conducted using the DOE/RECON computerized data base and other sources. Only tabular or graphic material was abstracted from the documents. The material has been organized in two ways: by the intended end use, i.e., vehicles, utility load leveling, residential load leveling, industrial, and solar, and within each end use, by technology. The summary tables attempt to compare the results of different studies of the same technology or end use. No attempt is made to summarize the conclusions of each individual study, but rather to point out areas of agreement or disagreement between them. The reader should be aware of the risks in making comparisons between studies conducted by researchers with possibly differing purposes and assumptions. Any conclusions based on the summary sections are more indicative than definitive.

    A program to demonstrate Solvent Refined Coal (SRC) technology has been initiated by the US Department of Energy (DOE) in partnership with two industrial groups. Project management responsibility has been assigned to the Oak Ridge Operations Office (ORO) of DOE. ORO requested that the Oak Ridge National Laboratory assess current research and development (R and D) activities and develop recommendations for those activities that might contribute to successful completion of the SRC demonstration plant projects. The objectives of this final report are to discuss in detail the problem areas in SRC; to discuss the current and planned R and D investigations relevant to the problems identified; and to suggest appropriate R and D activities in support of designs for the SRC demonstration plants. Four types of R and D activities are suggested: continuation of present and planned activities; coordination of activities and results, present and proposed; extension/redirection of activities not involving major equipment purchase or modifications; and new activities. Important examples of the first type of activity include continuation of fired heater, slurry rheology, and slurry mixing studies at Ft. Lewis. Among the second type of activity, coordination of data acquisition and interpretation is recommended in the areas of heat transfer, vapor/liquid equilibria, and physical properties. Principal examples of recommendations for extension/redirection include screening studies at laboratory scale on the use of carbonaceous precoat (e.g., anthracite) infiltration, and 15- to 30-day continuous tests of the Texaco gasifier at the Texaco Montebello facility (using SRC residues).

    This report summarizes an assessment of technology available to develop a noninvasive life detector for use on the battlefield. The detectors determine if casualties wearing chemical protective overgarments are alive or dead without further exposing either the casualties or the aidmen to the contaminated environment. Seven technology approaches sponsored by the Department of Defense (comprising 11 devices), four technologies identified in a market survey, and one device described in a Broad Agency Announcement proposal were examined as candidate Advanced Life Detectors. The technologies and instruments surveyed included three transmitter-receiver technologies, an electrocardiogram (ECG) technology, pacemaker-transmitter/receiver, dry electrode heart rate monitor, five microwave technologies, flash reflectance oximetry, an ultrasound technology, a streaming potential technology, a dry electrode ECG monitor coupled to a microphone, a statometric technique for determining heart rate and blood pressure, and a vital-signs monitor that determines heart rate and blood pressure using blood pressure cuff and microphones incorporated into the cuff. Analysis of the state-of-the-art of each device indicates that none of them are advanced enough to fulfill all the requirements of the draft Joint Services Operational Requirement. Three of the devices identified are recommended for further evaluation.

    The purpose of the Socio-economic Assessment is threefold in nature: to describe the socio-economic forces at work within the rural and urban areas throughout the Rocky Mountain Region (the Region); to develop social and economic profiles for the Region as a whole and each of its eight subregions; and, finally, to describe the potential impacts of the above mentioned forces on the Region and to make recommendations for developing future strategies to facilitate coordination between the Forest Service, the various state, local, and other federal agencies, and Native American Indian tribes. This project involved the analysis of various social and economic variables in an attempt to determine the social and economic situation in the Rocky Mountain Region, and how it has been altered over the last three decades. To this end, data was collected on demographic changes, income growth, employment and unemployment, payrolls, number and size of firms, and SIC industrial breakdowns for various industries within each subregion and economic impact area.

    The purpose of this study was to prospectively use a whole-heart three-dimensional (3D) coronary magnetic resonance (MR) angiography technique specifically adapted for use at 3 T and a parallel imaging technique (sensitivity encoding) to evaluate coronary arterial anomalies and variants (CAAV). This HIPAA-compliant study was approved by the local institutional review board, and informed consent was obtained from all participants. Twenty-two participants (11 men, 11 women; age range, 18-62 years) were included. Ten participants were healthy volunteers, whereas 12 participants were patients suspected of having CAAV. Coronary MR angiography was performed with a 3-T MR imager. A 3D free-breathing navigator-gated and vector electrocardiographically-gated segmented k-space gradient-echo sequence with adiabatic T2 preparation pulse and parallel imaging (sensitivity encoding) was used. Whole-heart acquisitions (repetition time msec/echo time msec, 4/1.35; 20 degrees flip angle; 1 x 1 x 2-mm acquired voxel size) lasted 10-12 minutes. Mean examination time was 41 minutes +/- 14 (standard deviation). Findings included aneurysms, ectasia, arteriovenous fistulas, and anomalous origins. The 3D whole-heart acquisitions developed for use with 3 T are feasible for use in the assessment of CAAV. PMID:18372470

    A Transportable Grout Facility is being constructed at the Hanford Site to immobilize low-level liquid radioactive waste in grout. This report addresses the grout and sediment testing methodology that is being developed at PNL to support assessments of the long-term performance of the disposed grout. Sediment is the soil that surrounds and underlies the disposed grout. A goal of these efforts is to certify tests for application at Hanford. An assessment of the long-term risks posed by grout requires data on the ability of grout to resist leaching of wastes contained within the grout. Additionally, data are needed on the ability of the sediments to retard the mobility of any wastes released from grout. The effects of aging on the ability of grout to retain waste must also be understood. Aging of grout can reduce or enhance the ability of the grout to contain waste. Credible predictive modeling of the fate of hazardous constituents in disposed grout for periods of up to 10,000 years would best be performed using comprehensive, coupled hydrologic and chemical reaction codes based on knowledge of the mechanisms that control waste release and mobility. It is not clear yet how soon such codes will be available or which types of waste disposal options they will apply to. In the interim we must be content with simpler and separate models that address individual reactions such as leaching and adsorption. One of these models, the Semi-Infinite Solid Diffusion Leach Model, is a popular release model used to describe the leaching of grouts and other cemented waste forms. Because others have found success in describing laboratory leach experiments with cemented waste forms using this leach model and because it appears likely to err on the conservative side for the Hanford application, we currently endorse the use of this model and its supporting experimental methodology for approximations of grout waste release rates. At the present time it is believed that the leachate from

  3. Counting Highly Cited Papers for University Research Assessment: Conceptual and Technical Issues

    A Kuhnian approach to research assessment requires us to consider that the important scientific breakthroughs that drive scientific progress are infrequent and that the progress of science does not depend on normal research. Consequently, indicators of research performance based on the total number of papers do not accurately measure scientific progress. Similarly, those universities with the best reputations in terms of scientific progress differ widely from other universities in terms of the scale of investments made in research and in the higher concentrations of outstanding scientists present, but less so in terms of the total number of papers or citations. This study argues that indicators for the 1% high-citation tail of the citation distribution reveal the contribution of universities to the progress of science and provide quantifiable justification for the large investments in research made by elite research universities. In this tail, which follows a power low, the number of the less frequent and highly cited important breakthroughs can be predicted from the frequencies of papers in the upper part of the tail. This study quantifies the false impression of excellence produced by multinational papers, and by other types of papers that do not contribute to the progress of science. Many of these papers are concentrated in and dominate lists of highly cited papers, especially in lower-ranked universities. The h-index obscures the differences between higher- and lower-ranked universities because the proportion of h-core papers in the 1% high-citation tail is not proportional to the value of the h-index.

    Ecosystems, and the biodiversity and services they support, are intrinsically dependent on climate. During the twentieth century, climate change has had documented impacts on ecological systems, and impacts are expected to increase as climate change continues and perhaps even accelerates. This technical input to the National Climate Assessment synthesizes our scientific understanding of the way climate change is affecting biodiversity, ecosystems, ecosystem services, and what strategies might be employed to decrease current and future risks. Building on past assessments of how climate change and other stressors are affecting ecosystems in the United States and around the world, we approach the subject from several different perspectives. First, we review the observed and projected impacts on biodiversity, with a focus on genes, species, and assemblages of species. Next, we examine how climate change is affecting ecosystem structural elements—such as biomass, architecture, and heterogeneity—and functions—specifically, as related to the fluxes of energy and matter. People experience climate change impacts on biodiversity and ecosystems as changes in ecosystem services; people depend on ecosystems for resources that are harvested, their role in regulating the movement of materials and disturbances, and their recreational, cultural, and aesthetic value. Thus, we review newly emerging research to determine how human activities and a changing climate are likely to alter the delivery of these ecosystem services. This technical input also examines two cross-cutting topics. First, we recognize that climate change is happening against the backdrop of a wide range of other environmental and anthropogenic stressors, many of which have caused dramatic ecosystem degradation already. This broader range of stressors interacts with climate change, and complicates our abilities to predict and manage the impacts on biodiversity, ecosystems, and the services they support. The

    Background: Despite the benefits of the objective structured assessment of technical skills (OSATS) and it appropriateness for evaluating clinical abilities of nursing students , few studies are available on the application of this method in nursing education. Objectives: The purpose of this study was to compare the effect of using OSATS and traditional methods on the students’ learning. We also aimed to signify students’ views about these two methods and their views about the scores they received in these methods in a medical emergency course. Patients and Methods: A quasi-experimental study was performed on 45 first semester students in nursing and medical emergencies passing a course on fundamentals of practice. The students were selected by a census method and evaluated by both the OSATS and traditional methods. Data collection was performed using checklists prepared based on the ‘text book of nursing procedures checklists’ published by Iranian nursing organization and a questionnaire containing learning rate and students’ estimation of their received scores. Descriptive statistics as well as paired t-test and independent samples t-test were used in data analysis. Results: The mean of students’ score in OSATS was significantly higher than their mean score in traditional method (P = 0.01). Moreover, the mean of self-evaluation score after the traditional method was relatively the same as the score the students received in the exam. However, the mean of self-evaluation score after the OSATS was relatively lower than the scores the students received in the OSATS exam. Most students believed that OSATS can evaluate a wide range of students’ knowledge and skills compared to traditional method. Conclusions: Results of this study indicated the better effect of OSATS on learning and its relative superiority in precise assessment of clinical skills compared with the traditional evaluation method. Therefore, we recommend using this method in evaluation of

    Ashes produced by thermal treatments of sewage sludge exhibit common properties with cement. For example, major elements present in SSA are the same of major elements of cement. Hydraulic properties of SSA are quite the same of cement ones. They may therefore be used to substitute part of cement in concrete or other cementitious materials, provided that technical prescriptions are satisfied and that environmental risks are not significantly increased. The objective of the present study was to determine the appropriate substitution ratios to satisfy both technical and environmental criteria. In a first step, the elemental composition and particle size distribution of the ashes were measured. Then the ashes were used along with Portland cement and sand at different ratios of substitution to produce mortar and concrete which were cured for up to 90 days into parallelepipedic or cylindrical monoliths. The mechanical properties of the monoliths were measured using standard procedures for flexural and compressive strengths, and compared to blanks containing no ashes. The environmental criteria were assessed using leaching tests conducted according to standard protocols both on the ashes and the monoliths, and compared to the blanks. Results showed that the characteristics of the ashes ranged between those of cement and sand because of their larger particle size and higher content in SiO2 as compared to cement. The monoliths made with the highest substitution ratios exhibited a significant decrease in flexural and compressive strengths. However, when the ashes were used in partial substitution of cement at appropriate ratios, the concrete monoliths exhibited similar compressive strengths as the blank samples. The most appropriate ratios were found to be 10% substitution of cement and 2% substitution of sand. The leaching tests conducted on the ashes in their powdery form revealed that amongst the potential contaminants analyzed only Mo and Se were leached at

    The load-following capability of fluidized bed combustion-augmented compressed air energy storage systems was evaluated. The results are presented in two parts. The first part is an Executive Summary which provides a concise overview of all major elements of the study including the conclusions, and, second, a detailed technical report describing the part-load and load following capability of both the pressurized fluid bed combustor and the entire pressurized fluid bed combustor/compressed air energy storage system. The specific tasks in this investigation were to: define the steady-state, part-load operation of the CAES open-bed PFBC; estimate the steady-state, part-load performance of the PFBC/CAES system and evaluate any possible operational constraints; simulate the performance of the PFBC/CAES system during transient operation and assess the load following capability of the system; and establish a start-up procedure for the open-bed PFBC and evaluate the impact of this procedure. The conclusions are encouraging and indicate that the open-bed PFBC/CAES power plant should provide good part-load and transient performance, and should have no major equipment-related constraints, specifically, no major problems associated with the performance or design of either the open-end PFBC or the PFBC/CAES power plant in steady-state, part-load operation are envisioned. The open-bed PFBC/CAES power plant would have a load following capability which would be responsive to electric utility requirements for a peak-load power plant. The open-bed PFBC could be brought to full operating conditions within 15 min after routine shutdown, by employing a hot-start mode of operation. The PFBC/CAES system would be capable of rapid changes in output power (12% of design load per minute) over a wide output power range (25% to 100% of design output). (LCL)

    Technical assessment and remodeling of existing data indicates that the Richton salt dome, located in southeastern Mississippi, appears to be a suitable site for expansion of the U.S. Strategic Petroleum Reserve. The maximum area of salt is approximately 7 square miles, at a subsurface elevation of about -2000 ft, near the top of the salt stock. Approximately 5.8 square miles of this appears suitable for cavern development, because of restrictions imposed by modeled shallow salt overhang along several sides of the dome. The detailed geometry of the overhang currently is only poorly understood. However, the large areal extent of the Richton salt mass suggests that significant design flexibility exists for a 160-million-barrel storage facility consisting of 16 ten-million-barrel caverns. The dome itself is prominently elongated from northwest to southeast. The salt stock appears to consist of two major spine features, separated by a likely boundary shear zone trending from southwest to northeast. The dome decreases in areal extent with depth, because of salt flanks that appear to dip inward at 70-80 degrees. Caprock is present at depths as shallow as 274 ft, and the shallowest salt is documented at -425 ft. A large number of existing two-dimensional seismic profiles have been acquired crossing, and in the vicinity of, the Richton salt dome. At least selected seismic profiles should be acquired, examined, potentially reprocessed, and interpreted in an effort to understand the limitations imposed by the apparent salt overhang, should the Richton site be selected for actual expansion of the Reserve.

    A technical assessment of the critical issues and problem areas in the field of plasma materials interactions (PMI) in magnetic fusion devices shows these problems to be central for near-term experiments, for intermediate-range reactor devices including D-T burning physics experiments, and for long-term reactor machines. Critical technical issues are ones central to understanding and successful operation of existing and near-term experiments/reactors or devices of great importance for the long run, i.e., ones which will require an extensive, long-term development effort and thus should receive attention now. Four subgroups were formed to assess the critical PMI issues along four major lines: (1) PMI and plasma confinement physics experiments; (2) plasma-edge modelling and theory; (3) surface physics; and (4) materials technology for in-vessel components and the first wall. The report which follows is divided into four major sections, one for each of these topics.

    Heavy fractions resulting from mechanical treatment stages of mechanical-biological waste treatment plants are posing very specific demands with regard to further treatment (large portions of inert and high-caloric components). Based on the current Austrian legal situation such a waste stream cannot be landfilled and must be thermally treated. The aim of this research was to evaluate if an inert fraction generated from this waste stream with advanced separation technologies, two sensor-based [near-infrared spectroscopy (NIR), X-ray transmission (XRT)] and two mechanical systems (wet and dry) is able to be disposed of. The performance of the treatment options for separation was evaluated by characterizing the resulting product streams with respect to purity and yield. Complementing the technical evaluation of the processing options, an assessment of the economic and global warming effects of the change in waste stream routing was conducted. The separated inert fraction was evaluated with regard to landfilling. The remaining high-caloric product stream was evaluated with regard to thermal utilization. The results show that, in principal, the selected treatment technologies can be used to separate high-caloric from inert components. Limitations were identified with regard to the product qualities achieved, as well as to the economic expedience of the treatment options. One of the sensor-based sorting systems (X-ray) was able to produce the highest amount of disposeable heavy fraction (44.1%), while having the lowest content of organic (2.0% C biogenic per kg waste input) components. None of the high-caloric product streams complied with the requirements for solid recovered fuels as defined in the Austrian Ordinance on Waste Incineration. The economic evaluation illustrates the highest specific treatment costs for the XRT (€ 23.15 per t), followed by the NIR-based sorting system (€ 15.67 per t), and the lowest costs for the air separation system (€ 10.79 per t

    The Hand1- and Cmya1-ESTs are novel short-term tests for embryotoxic chemicals using genetically engineering mouse ES cells for luciferase reporter gene assays. These ESTs allow convenient determination of differentiation toxicity and cell viability in a short duration with high throughput 96-well microplates for prediction of embryotoxicity of chemicals. To assess the Hand1-EST technical protocol, we firstly compared reporter gene assay and cytotoxicity test data for a representative compound (hydroxyurea) from four different laboratories with tests carried out under the same experimental conditions. Extensive investigations of the Hand1- and Cmya1-ESTs were then performed to explore reproducibility by comparing a set of 6 well-known test chemicals, including hydroxyurea, across the laboratories. The results gave good correspondence in all four laboratories, indicating that transferability, intra-laboratory variability and inter-laboratory variability of the present technical protocols of the ESTs were sufficient to conduct further validation studies.

    The U.S. Department of Energy (DOE) is currently evaluating the water management procedures at the Separations Process Research Unit (SPRU). The facility has three issues related to water management that require technical assistance: (1) due to a excessive rainfall event in October, 2010, contaminated water collected in basements of G2 and H2 buildings. As a result of this event, the contractor has had to collect and dispose of water offsite; (2) The failure of a sump pump at a KAPL outfall resulted in a Notice of Violation issued by the New York State Department of Environment and Conservation (NYSDEC) and subsequent Consent Order. On-site water now requires treatment and off-site disposition; and (3) stormwater infiltration has resulted in Strontium-90 levels discharged to the storm drains that exceed NR standards. The contractor has indicated that water management at SPRU requires major staff resources (at least 50 persons).

    2008-01-01

    The purpose of the U.S. Geological Survey's (USGS) National Oil and Gas Assessment is to develop geology-based hypotheses regarding the potential for additions to oil and gas reserves in priority areas of the United States, focusing on the distribution, quantity, and availability of oil and natural gas resources. The USGS has completed an assessment of the undiscovered, technically recoverable coalbed-gas resources in Cretaceous and Tertiary rocks underlying the North Slope and adjacent State waters of Alaska (USGS Northern Alaska Province 5001). The province is a priority Energy Policy and Conservation Act (EPCA) province for the National Assessment because of its potential for oil and gas resources. The assessment of this province is based on geologic principles and uses the total petroleum system concept. The geologic elements of a total petroleum system include hydrocarbon source rocks (source rock maturation, hydrocarbon generation and migration), reservoir rocks (stratigraphy, sedimentology, petrophysical properties), and hydrocarbon traps (trap formation and timing). In the Northern Alaska Province, the USGS used this geologic framework to define one composite coalbed gas total petroleum system and three coalbed gas assessment units within the petroleum system, and quantitatively estimated the undiscovered coalbed-gas resources within each assessment unit.

    Two terms, two job categories, 'technical writer' and 'technical author' are discussed in terms of industrial and business requirements and standards. A distinction between 'technical writing' and technical 'writing' is made. The term 'technical editor' is also considered. Problems inherent in the design of programs to prepare and train students for these jobs are discussed. A closer alliance between industry and academia is suggested as a means of preparing students with competent technical communication skills (especially writing and editing skills) and good technical skills.

    2007-09-11

    An exceptional number of Middle Eastern and North African nations have recently expressed interest in developing nuclear energy for peaceful purposes. Many of these countries have explored nuclear research in limited ways in the past, but the current focused interest and application of resources towards developing nuclear-generated electricity and nuclear-powered desalination plants is unprecedented. Consequently, questions arise in response to this emerging trend: What instigated this interest? To what end(s) will a nuclear program be applied? Does the country have adequate technical, political, legislative, nonproliferation, and safety infrastructure required for the capability desired? If so, what are the next steps for a country in preparation for a future nuclear program? And if not, what collaboration efforts are possible with the United States or others? This report provides information on the capabilities and interests of 13 countries in the region in nuclear energy programs in light of safety, nonproliferation and security concerns. It also provides information useful for determining potential for offering technical collaboration, financial aid, and/or political support.

  14. A Socio-technical assessment of the success of picture archiving and communication systems: the radiology technologist’s perspective

    PubMed Central

    2013-01-01

    Background With the increasing prevalence of Picture Archiving and Communication Systems (PACS) in healthcare institutions, there is a growing need to measure their success. However, there is a lack of published literature emphasizing the technical and social factors underlying a successful PACS. Methods An updated Information Systems Success Model was utilized by radiology technologists (RTs) to evaluate the success of PACS at a large medical center in Taiwan. A survey, consisting of 109 questionnaires, was analyzed by Structural Equation Modeling. Results Socio-technical factors (including system quality, information quality, service quality, perceived usefulness, user satisfaction, and PACS dependence) were proven to be effective measures of PACS success. Although the relationship between service quality and perceived usefulness was not significant, other proposed relationships amongst the six measurement parameters of success were all confirmed. Conclusions Managers have an obligation to improve the attributes of PACS. At the onset of its deployment, RTs will have formed their own subjective opinions with regards to its quality (system quality, information quality, and service quality). As these personal concepts are either refuted or reinforced based on personal experiences, RTs will become either satisfied or dissatisfied with PACS, based on their perception of its usefulness or lack of usefulness. A satisfied RT may play a pivotal role in the implementation of PACS in the future. PMID:24053458

    1985-06-01

    Purpose of this study is to explore the status of R and D in Japan and the ability of US researchers to keep abreast of Japanese technical advances. US researchers familiar with R and D activities in Japan were interviewed in ten fields that are relevant to the more efficient use of energy: amorphous metals, biotechnology, ceramics, combustion, electrochemical energy storage, heat engines, heat transfer, high-temperature sensors, thermal and chemical energy storage, and tribology. The researchers were questioned about their perceptions of the strengths of R and D in Japan, comparative aspects of US work, and the quality of available information sources describing R and D in Japan. Of the ten related fields, the researchers expressed a strong perception that significant R and D is under way in amorphous metals, biotechnology, and ceramics, and that the US competitive position in these technologies will be significantly challenged. Researchers also identified alternative emphases in Japanese R and D programs in these areas that provide Japan with stronger technical capabilities. For example, in biotechnology, researchers noted the significant Japanese emphasis on industrial-scale bioprocess engineering, which contrasts with a more meager effort in the US. In tribology, researchers also noted the strength of the chemical tribology research in Japan and commented on the effective mix of chemical and mechanical tribology research. This approach contrasts with the emphasis on mechanical tribology in the US.

    The National Nuclear Security Administration, Nevada Operations Office (NNSA/NV) operates and maintains two active facilities on the Nevada Test Site (NTS) that dispose Department of Energy (DOE) defense-generated low-level radioactive (LLW), mixed radioactive, and classified waste in shallow trenches, pits and large-diameter boreholes. The operation and maintenance of the LLW disposal sites are self-regulated under DOE Order 435.1, which requires review of a Performance Assessment for four performance objectives: 1) all pathways 25 mrem/yr limit; 2) atmospheric pathways 10 mrem/yr limit; 3) radon flux density of 20 pCi/m2/s; and 4) groundwater resource protection (Safe Drinking Water Act; 4 mrem/yr limit). The inadvertent human intruder is protected under a dual 500- and 100-mrem limit (acute and chronic exposure). In response to the Defense Nuclear Facilities Safety Board Recommendation 92 2, a composite analysis is required that must examine all interacting sources for compliance against both 30 and 100 mrem/yr limits. A small component of classified transuranic waste is buried at intermediate depths in 3-meter diameter boreholes at the Area 5 LLW disposal facility and is assessed through DOE-agreement against the requirements of the Environmental Protection Agency (EPA)'s 40 CFR 191. The hazardous components of mixed LLW are assessed against RCRA requirements. The NTS LLW sites fall directly under three sets of federal regulations and the regulatory differences result not only in organizational challenges, but also in different decision objectives and technical paths to completion. The DOE regulations require deterministic analysis for a 1,000-year compliance assessment supplemented by probabilistic analysis under a long-term maintenance program. The EPA regulations for TRU waste are probabilistically based for a compliance interval of 10,000 years. Multiple steps in the assessments are strongly dependent on assumptions for long-term land use policies

    2009-07-28

    Research is being conducted for the U.S. Nuclear Regulatory Commission (NRC) at the Pacific Northwest National Laboratory (PNNL) to assess the effectiveness and reliability of advanced nondestructive examination (NDE) methods for the inspection of light water reactor components. The scope of this research encompasses primary system pressure boundary materials including cast austenitic stainless steels (CASS); dissimilar metal welds; piping with corrosion-resistant cladding; weld overlays, inlays and onlays; and far-side examinations of austenitic piping welds. A primary objective of this work is to evaluate various NDE methods to assess their ability to detect, localize, and size cracks in coarse-grained steel components. In this effort, PNNL supports cooperation with Commissariat à l’Energie Atomique (CEA) to assess reliable inspection of CASS materials. The NRC Project Manager has established a cooperative effort with the Institut de Radioprotection et de Surete Nucleaire (IRSN). CEA, under funding from IRSN, are supporting collaborative efforts with the NRC and PNNL. Regarding its work on the NDE of materials, CEA is providing its modeling software (CIVA) in exchange for PNNL offering expertise and data related to phased-array detection and sizing, acoustic attenuation, and back scattering on CASS materials. This collaboration benefits the NRC because CEA performs research and development on CASS for Électricité de France (EdF). This technical letter report provides a summary of a technical evaluation aimed at assessing the capabilities of phased-array (PA) ultrasonic testing (UT) methods as applied to the inspection of welds in CASS pressurizer (PZR) surge line nuclear reactor piping. A set of thermal fatigue cracks (TFCs) was implanted into three CASS PZR surge-line specimens (pipe-to-elbow welds) that were fabricated using vintage CASS materials formed in the 1970s, and flaw responses from these cracks were used to evaluate detection and sizing

    Background Human error and deficient non-technical skills (NTSs) among providers of ALS in helicopter emergency medical services (HEMS) is a threat to patient and operational safety. Skills can be improved through simulation-based training and assessment. Objective To document the current level of simulation-based training and assessment of seven generic NTSs in crew members in the Norwegian HEMS. Methods A cross-sectional survey, either electronic or paper-based, of all 207 physicians, HEMS crew members (HCMs) and pilots working in the civilian Norwegian HEMS (11 bases), between 8 May and 25 July 2012. Results The response rate was 82% (n=193). A large proportion of each of the professional groups lacked simulation-based training and assessment of their NTSs. Compared with pilots and HCMs, physicians undergo statistically significantly less frequent simulation-based training and assessment of their NTSs. Fifty out of 82 (61%) physicians were on call for more than 72 consecutive hours on a regular basis. Of these, 79% did not have any training in coping with fatigue. In contrast, 72 out of 73 (99%) pilots and HCMs were on call for more than 3 days in a row. Of these, 54% did not have any training in coping with fatigue. Conclusions Our study indicates a lack of simulation-based training and assessment. Pilots and HCMs train and are assessed more frequently than physicians. All professional groups are on call for extended hours, but receive limited training in how to cope with fatigue. PMID:25344577

    1982-07-01

    Binary cycle power plants have been the subject of much discussion among engineers and scientists for nearly 100 years. Current economic and environmental concerns have stimulated new interest and research. Ammonia has been recommended by other studies as the leading contender for use as simply the heat rejection medium in an air-cooled power plant. This study investigates the technical feasibility and economic potential of including an expander in the heat rejection system of an air-cooled power plant. The expander would be used during certain parts of the year to increase the total output of the power plant. Five different plant locations (Miami, San Francisco, Bakersfield, Chicago, Anchorage) were investigated to show the effect which climate has on the economic potential of this ammonia bottoming cycle. The study shows that the expected energy costs for the bottoming cycle only will be less than 50 mills/kWh for any of the five plant locations. This cost assumes that an ammonia phase-change heat rejection system is already a part of the existing plant.

A detailed process model was developed in ASPEN Plus{trademark} to perform material and energy balances. The results of this simulation were used to size and cost major pieces of equipment from which the determination of the necessary selling price of hydrogen was made. A sensitivity analysis was conducted on the process to study hydrogen price as a function of biomass feedstock cost and hydrogen production efficiency. The gasification system used for this study was the Battelle Columbus Laboratory (BCL) indirectly heated gasifier. The heat necessary for the endothermic gasification reactions is supplied by circulating sand from a char combustor to the gasification vessel. Hydrogen production was accomplished by steam reforming the product synthesis gas (syngas) in a process based on that used for natural gas reforming. Three process configurations were studied. Scheme 1 is the full reforming process, with a primary reformer similar to a process furnace, followed by a high temperature shift reactor and a low temperature shift reactor. Scheme 2 uses only the primary reformer, and Scheme 3 uses the primary reformer and the high temperature shift reactor. A pressure swing adsorption (PSA) system is used in all three schemes to produce a hydrogen product pure enough to be used in fuel cells. Steam is produced through detailed heat integration and is intended to be sold as a by-product.

    A technical analysis has been completed for a commercial-scale two-stage gasification-combustion system. The CLEERGAS (Covanta Low Emissions Energy Recovery GASification) process consists of partial combustion and gasification of as-received municipal solid waste (MSW) on a moving grate producing syngas followed by full combustion of the generated syngas in an adjoining chamber and boiler. This process has been in operation since 2009 on a modified 330-tonne day(-1) waste-to-energy (WTE) line in Tulsa, Oklahoma. Material balances determined that the syngas composition is 12.8% H2 and 11.4% CO, the heating value of the gas in the gasifier section is 4098 kJ Nm(-3), and an aggregate molecular formula for the waste is C6H14.5O5. The analysis of gas measurements sampled from the Tulsa unit showed that the gasification-combustion mode fully processed the MSW at an excess air input of only 20% as compared to the 80-100% typically found in conventional WTE moving grate plants. Other important attributes of the CLEERGAS gasification-combustion process are that it has operated on a commercial scale for a period of over two years with 93% availability and utilizes a moving grate technology that is currently used in hundreds of WTE plants around the world.

    The Risk Assessment for the Retrieval of Transuranic Waste is a comparative risk assessment of the potential adverse human health effects resulting from exposure to contaminants during retrieval and post-retrieval aboveground storage operations of post-1970 earthen-covered transuranic waste. Two alternatives are compared: (1) Immediate Retrieval and (2) Delayed Retrieval. Under the Immediate Retrieval Alternative, retrieval of the waste is assumed to begin immediately, Under the Delayed Retrieval Alternative, retrieval is delayed 10 years. The current risk assessment is on Pads 1, 2, and 4, at Technical Area-54, Area-G, Los Alamos National Laboratory (LANL). Risks are assessed independently for three scenarios: (1) incident-free retrieval operations, (2) incident-free storage operations, and (3) a drum failure analysis. The drum failure analysis evaluates container integrity under both alternatives and assesses the impacts of potential drum failures during retrieval operations. Risks associated with a series of drum failures are potentially severe for workers, off-site receptors, and general on-site employees if retrieval is delayed 10 years and administrative and engineering controls remain constant. Under the Delayed Retrieval Alternative, an average of 300 drums out of 16,647 are estimated to fail during retrieval operations due to general corrosion, while minimal drums are predicted to fail under the Immediate Retrieval Alternative. The results of the current study suggest that, based on risk, remediation of Pads 1, 2, and 4 at LANL should not be delayed. Although risks from incident-free operations in the Delayed Retrieval Alternative are low, risks due to corrosion and drum failures are potentially severe.

    Aim To describe and assess the scientific and technical aspects of animal forensic testing at the University of California, Davis. The findings and recommendations contained in this report are designed to assess the past, evaluate the present, and recommend reforms that will assist the animal forensic science community in providing the best possible services that comply with court standards and bear judicial scrutiny. Methods A batch of 32 closed files of domestic dog DNA cases processed at the University of California, Davis, between August 2003 and July 2005 were reviewed in this study. The case files comprised copies of all original paperwork, copies of the cover letter or final report, laboratory notes, notes on analyses, submission forms, internal chains of custody, printed images and photocopies of evidence, as well as the administrative and technical reviews of those cases. Results While the fundamental aspects of animal DNA testing may be reliable and acceptable, the scientific basis for forensic testing animal DNA needs to be improved substantially. In addition to a lack of standardized and validated genetic testing protocols, improvements are needed in a wide range of topics including quality assurance and quality control measures, sample handling, evidence testing, statistical analysis, and reporting. Conclusion This review implies that although a standardized panel of short tandem repeat and mitochondrial DNA markers and publicly accessible genetic databases for canine forensic DNA analysis are already available, the persistent lack of supporting resources, including standardized quality assurance and quality control programs, still plagues the animal forensic community. This report focuses on closed cases from the period 2003-2005, but extends its scope more widely to include other animal DNA forensic testing services. PMID:21674824

    2016-02-01

    The assessment of the efficiency of wastewater treatment plants (WWTPs) is essential to compare their performance and consequently to identify the best operational practices that can contribute to the reduction of operational costs. Previous studies have evaluated the efficiency of WWTPs using conventional data envelopment analysis (DEA) models. Most of these studies have considered the operational costs of the WWTPs as inputs, while the pollutants removed from wastewater are treated as outputs. However, they have ignored the fact that each pollutant removed by a WWTP involves a different environmental impact. To overcome this limitation, this paper evaluates for the first time the efficiency of a sample of WWTPs by applying the weighted slacks-based measure model. It is a non-radial DEA model which allows assigning weights to the inputs and outputs according their importance. Thus, the assessment carried out integrates environmental issues with the traditional "techno-economic" efficiency assessment of WWTPs. Moreover, the potential economic savings for each cost item have been quantified at a plant level. It is illustrated that the WWTPs analyzed have significant room to save staff and energy costs. Several managerial implications to help WWTPs' operators make informed decisions were drawn from the methodology and empirical application carried out. PMID:26686068

    At the U.S. Department of Energy (DOE) Hanford Site, the Waste Treatment Plant (WTP) is being constructed to immobilize both high-level waste (IUW) for disposal in a national repository and low-activity waste (LAW) for onsite, near-surface disposal. The schedule-controlling step for the WTP Project is vitrification of the large volume of LAW, current capacity of the WTP (as planned) would require 50 years to treat the Hanford tank waste, if the entire LAW volume were to be processed through the WTP. To reduce the time and cost for treatment of Hanford Tank Waste, and as required by the Tank Waste Remediation System Environmental Impact Statement Record of Decision and the Hanford Federal Facility Consent Agreement (Tn-Party Agreement), DOE plans to supplement the LAW treatment capacity of the WTP. Since 2002, DOE, in cooperation with the Environmental Protection Agency and State of Washington Department of Ecology has been evaluating technologies that could provide safe and effective supplemental treatment of LAW. Current efforts at Hanford are intended to provide additional information to aid a joint agency decision on which technology will be used to supplement the WTP. A Research, Development and Demonstration permit has been issued by the State of Washington to build and (for a limited time) operate a Demonstration Bulk Vitrification System (DBVS) facility to provide information for the decision on a supplemental treatment technology for up to 50% of the LAW. In the Bulk Vitrification (BV) process, LAW, soil, and glass-forming chemicals are mixed, dried, and placed in a refractory-lined box, Electric current, supplied through two graphite electrodes in the box, melts the waste feed, producing a durable glass waste-form. Although recent modifications to the process have resulted in significant improvements, there are continuing technical concerns.

    Dengue is a rapidly growing public health threat with approximately 2.5 billion people estimated to be at risk. Several vaccine candidates are at various stages of pre-clinical and clinical development. Thus far, live dengue vaccine candidates have been administered to several thousands of volunteers and were well-tolerated, with minimal short-term safety effects reported in Phase I and Phase II clinical trials. Based on the natural history of dengue, a theoretical possibility of an increased risk of severe dengue as a consequence of vaccination has been hypothesized but not yet observed. In October 2011, the World Health Organization (WHO) convened a consultation of experts in dengue, vaccine regulation and vaccine safety to review the current scientific evidence regarding safety concerns associated with live attenuated dengue vaccines and, in particular, to consider methodological approaches for their long-term evaluation. In this paper we summarize the scientific background and methodological considerations relevant to the safety assessment of these vaccines. Careful planning and a coordinated approach to safety assessment are recommended to ensure adequate long-term evaluation of dengue vaccines that will support their introduction and continued use.

    There is a large uncertainty in quantifying the inhalation pathway and the aerosol emission rate in human health assessments of radioactive-contamination sites. The need for site-specific assessments led to formation of our team of specialists at LLNL, who have participated in numerous field campaigns around the world. Our goal was to obtain all the information necessary for determining potential human exposures and to estimate source terms for turbulent transport of the emissions during both normal and disturbed soil conditions. That is, measurements were made of the key variables to quantify the suspended aerosols at the actual contamination sites, but different scenarios for habitation, site management, and site cleanup were included. The most notable locations of these site-investigations were the Marshall Islands (Bikini, Enewetak, and Rongelap), Nevada Test Site (GMX, Little Feller, Palanquin, and Plutonium Valley), Tonopah (Nevada--site of Roller Coaster), Savannah River Lab (South Carolina--H-Area site), Johnston Island (cleanup of rocket-impact site), Chernobyl (Ukraine--grass field end sandy beach sites near Nuclear Power Plant Unit 4), and Palomares (Spain--site of aircraft accident). This discussion will review the variables quantified, methods developed, general results, uncertainty of estimations, and recommendations for future research that are a result of our experience in these field studies.

    Peripheral quantitative computed tomography (pQCT) has found new fields of application in bone medicine, but none of them concerns the forensic practice. This study exposes the potential of pQCT applied to a penetrating lesion in a vertebral body. A pQCT scanner was used for the measurements (XCT Research SA+; Stratec Medizintechnik GmbH, Pforzheim, Germany). A more precise reconstruction of the path of the lesion within the trabecular bone was reached, with more details concerning the morphological characteristics of the lesion inside the vertebral body, and the elaboration of a 3D model was created, which allowed the operator to define the volume of the lack of tissues related to the lesion. The application of pQCT scan proved to be a potentially useful tool for the assessment of bone lesions, although further studies are needed in order to verify its applicability to forensic context.

    The U.S. Nuclear Regulatory Commission (NRC) has a multi-year program at the Pacific Northwest National Laboratory (PNNL) to provide engineering studies and assessments of issues related to the use of nondestructive evaluation (NDE) methods for the reliable inspection of nuclear power plant components. As part of this program, there is a subtask 2D that was set up to address an assessment of issues related to the NDE of high density polyethylene (HDPE) butt fusion joints. This work is being driven by the nuclear industry wanting to employ HDPE materials in nuclear power plant systems. This being a new material for use in nuclear applications, there are a number of issues related to its use and potential problems that may evolve. The industry is pursuing ASME Code Case N-755 entitled “Use of Polyethylene (PE) Plastic Pipe for Section III, Division 1, Construction and Section XI Repair/Replacement Activities” that contains the requirements for nuclear power plant applications of HDPE. This Code Case requires that inspections be performed after the fusion joint is made by visually examining the bead that is formed and conducting a pressure test of the joint. These tests are only effective in general if gross through-wall flaws exist in the fusion joint. The NRC wants to know whether a volumetric inspection can be conducted on the fusion joint that will reliably detect lack-of-fusion conditions that may be produced during joint fusing. The NRC has requested that the work that PNNL is conducting be provided to assist them in resolving this inspection issue of whether effective volumetric NDE can be conducted to detect lack of fusion (LOF) in the butt HDPE joints. PNNL had 24 HDPE pipe specimens manufactured of 3408 material to contain LOF conditions that could be used to assess the effectiveness of NDE in detecting the LOF. Basic ultrasonic material properties were measured and used to guide the use of phased arrays and time-of-flight diffraction (TOFD) work that

    The purpose of this study was to prospectively use a whole-heart three-dimensional (3D) coronary magnetic resonance (MR) angiography technique specifically adapted for use at 3 T and a parallel imaging technique (sensitivity encoding) to evaluate coronary arterial anomalies and variants (CAAV). This HIPAA-compliant study was approved by the local institutional review board, and informed consent was obtained from all participants. Twenty-two participants (11 men, 11 women; age range, 18–62 years) were included. Ten participants were healthy volunteers, whereas 12 participants were patients suspected of having CAAV. Coronary MR angiography was performed with a 3-T MR imager. A 3D free-breathing navigator-gated and vector electrocardiographically–gated segmented k-space gradient-echo sequence with adiabatic T2 preparation pulse and parallel imaging (sensitivity encoding) was used. Whole-heart acquisitions (repetition time msec/echo time msec, 4/1.35; 20° flip angle; 1 × 1 × 2-mm acquired voxel size) lasted 10–12 minutes. Mean examination time was 41 minutes ± 14 (standard deviation). Findings included aneurysms, ectasia, arteriovenous fistulas, and anomalous origins. The 3D whole-heart acquisitions developed for use with 3 T are feasible for use in the assessment of CAAV. © RSNA, 2008 PMID:18372470

    On April 27, 1986, at least 8 million liters of medium-weight crude oil spilled from a ruptured storage tank into the Bahia Las Minas on the Caribbean Coast of Panama. Coral reefs, seagrass communities, and mangroves were affected. The area of the spill was also the location of the Smithsonian Tropical Research Institute's Galeta Laboratory where resident and visiting scientists have been studying the ecology of the Bahia Las Minas and the adjacent areas for over 15 years. Because this was a unique opportunity to assess the immediate biological effects following a major spill in the Caribbean region and to monitor the subsequent recovery, the U.S. Department of the Interior Minerals Management Service supported a 5-year environmental study. The objectives of the study are to identify any long-term changes in the marine environment that may have resulted from the spill and to understand the ecological processes causing such changes. This is the first report from the study and addresses the effects observed during the first two years of the effort.

    The Ames assay and Mutatox were evaluated to compare their ability to identify the genotoxic potential of dredged sediments. The Ames assay has been used extensively in the testing of environmental contaminants. Mutatox, a bacterial bioluminescence test, was developed as a genotoxicity bioassay. Ten sediments with varying degrees of contamination were soxhlet extracted. These extracts were divided into crude and clean samples. Cleaned samples were prepared using silica-gel chromatography resulting in 20 extract samples. Both the Ames test (TA98 and TAl00) and Mutatox were conducted with and without S9 metabolic activation. TA98+S9 and TA1OO+S9 indicated a positive mutagenic response in 80 and 50 percent, respectively, of the sediment extracts. Half of the extracts indicated a positive mutagenic response with TA98-S9, while only 10 percent did so with TAlOO-S9. Mutatox indicated a positive mutagenic response with S9 activation in 75 percent of the extracts and no mutagenic response in any of the sediment extracts without metabolic activation. In a side-by-side comparison of the Ames assay (TA98+S9) and Mutatox, 80 percent of the sediment extracts had similar responses, both positive and negative. Fifty percent of the sediment extracts had similar responses when tested with TAlOO+S9 and Mutatox. Mutatox compared favorably with the Ames assay and shows promise as a screening tool to assess sediment genotoxicity when used with Ames assay as a confirmation.

    The recovery of beverage cartons (BC) in three lightweight packaging waste processing plants (LP) was analyzed with different input materials and input masses in the area of 21-50Mg. The data was generated by gravimetric determination of the sorting products, sampling and sorting analysis. Since the particle size of beverage cartons is larger than 120mm, a modified sampling plan was implemented and targeted multiple sampling (3-11 individual samplings) and a total sample size of respectively 1200l (ca. 60kg) for the BC-products and of about 2400l (ca. 120kg) for material-heterogeneous mixed plastics (MP) and sorting residue products. The results infer that the quantification of the beverage carton yield in the process, i.e., by including all product-containing material streams, can be specified only with considerable fluctuation ranges. Consequently, the total assessment, regarding all product streams, is rather qualitative than quantitative. Irregular operation conditions as well as unfavorable sampling conditions and capacity overloads are likely causes for high confidence intervals. From the results of the current study, recommendations can basically be derived for a better sampling in LP-processing plants. Despite of the suboptimal statistical results, the results indicate very clear that the plants show definite optimisation potentials with regard to the yield of beverage cartons as well as the required product purity. Due to the test character of the sorting trials the plant parameterization was not ideal for this sorting task and consequently the results should be interpreted with care. PMID:26547410

The major recommendations of the staff paper include the following: (1) There continues to be a need to control ambient levels of carbon monoxide to protect public health; (2) Both 1-hour and 8-hour averaging times should be retained for primary carbon monoxide standards; (3) Exposure analysis results indicate relatively few individuals with angina pectoris would experience carboxyhemoglobin (COHb) levels of 2.1% or greater when exposed to carbon monoxide levels in ambient air only if current standards are attained; (4) Public health risk for COHb levels of 2.0% or lower appears to be small, if any; (5) Current 1-hour (35 ppm) and 8-hour (9 ppm) standards for carbon monoxide should be reaffirmed.

    1988-01-01

    Critical issues for the steady state operation of plasma confinement devices exist in both the physics and technology fields of fusion research. Due to the wide range and number of these issues, this technical assessment has focused on the crucial issues associated with the plasma physics and the plasma interactive components. The document provides information on the problem areas that affect the design and operation of a steady state ETR or ITER type confinement device. It discusses both tokamaks and alternative concepts, and provides a survey of existing and planned confinement machines and laboratory facilities that can address the identified issues. A universal definition of steady state operation is difficult to obtain. From a physics point of view, steady state is generally achieved when the time derivatives approach zero and the operation time greatly exceeds the characteristic time constants of the device. Steady state operation for materials depends on whether thermal stress, creep, fatigue, radiation damage, or power removal are being discussed. For erosion issues, the fluence and availability of the machine for continuous operation are important, assuming that transient events such as disruptions do not limit the component lifetimes. The panel suggests, in general terms, that steady state requires plasma operation from 100 to 1000 seconds and an availability of more than a few percent, which is similar to the expectations for an ETR type device. The assessment of critical issues for steady state operation is divided into four sections: physics issues; technology issues; issues in alternative concepts; and devices and laboratory facilities that can address these problems.

  17. Hawaii demand-side management resource assessment. Final report, Reference Volume 3 -- Residential and commercial sector DSM analyses: Detailed results from the DBEDT DSM assessment model; Part 1, Technical potential

    SciTech Connect

    1995-04-01

    The Hawaii Demand-Side Management Resource Assessment was the fourth of seven projects in the Hawaii Energy Strategy (HES) program. HES was designed by the Department of Business, Economic Development, and Tourism (DBEDT) to produce an integrated energy strategy for the State of Hawaii. The purpose of Project 4 was to develop a comprehensive assessment of Hawaii`s demand-side management (DSM) resources. To meet this objective, the project was divided into two phases. The first phase included development of a DSM technology database and the identification of Hawaii commercial building characteristics through on-site audits. These Phase 1 products were then used in Phase 2 to identify expected energy impacts from DSM measures in typical residential and commercial buildings in Hawaii. The building energy simulation model DOE-2.1E was utilized to identify the DSM energy impacts. More detailed information on the typical buildings and the DOE-2.1E modeling effort is available in Reference Volume 1, ``Building Prototype Analysis``. In addition to the DOE-2.1E analysis, estimates of residential and commercial sector gas and electric DSM potential for the four counties of Honolulu, Hawaii, Maui, and Kauai through 2014 were forecasted by the new DBEDT DSM Assessment Model. Results from DBEDTs energy forecasting model, ENERGY 2020, were linked with results from DOE-2.1E building energy simulation runs and estimates of DSM measure impacts, costs, lifetime, and anticipated market penetration rates in the DBEDT DSM Model. Through its algorithms, estimates of DSM potential for each forecast year were developed. Using the load shape information from the DOE-2.1E simulation runs, estimates of electric peak demand impacts were developed. Numerous tables and figures illustrating the technical potential for demand-side management are included.

    Washington River Protection Solutions (WRPS) and its contractors at Pacific Northwest National Laboratory (PNNL) and Savannah River National Laboratory (SRNL) are conducting a development program to develop / refine the cementitious waste form for the wastes treated at the ETF and to provide the data needed to support the IDF PA. This technical approach document is intended to provide guidance to the cementitious waste form development program with respect to the waste form characterization and testing information needed to support the IDF PA. At the time of the preparation of this technical approach document, the IDF PA effort is just getting started and the approach to analyze the performance of the cementitious waste form has not been determined. Therefore, this document looks at a number of different approaches for evaluating the waste form performance and describes the testing needed to provide data for each approach. Though the approach addresses a cementitious secondary aqueous waste form, it is applicable to other waste forms such as Cast Stone for supplemental immobilization of Hanford LAW. The performance of Cast Stone as a physical and chemical barrier to the release of contaminants of concern (COCs) from solidification of Hanford liquid low activity waste (LAW) and secondary wastes processed through the Effluent Treatment Facility (ETF) is of critical importance to the Hanford Integrated Disposal Facility (IDF) total system performance assessment (TSPA). The effectiveness of cementitious waste forms as a barrier to COC release is expected to evolve with time. PA modeling must therefore anticipate and address processes, properties, and conditions that alter the physical and chemical controls on COC transport in the cementitious waste forms over time. Most organizations responsible for disposal facility operation and their regulators support an iterative hierarchical safety/performance assessment approach with a general philosophy that modeling provides

    DNA extracted from formalin-fixed, paraffin-embedded (FFPE) tissues has been used in the past to analyze genetic polymorphisms. We evaluated the technical reproducibility of different types of assays for gene polymorphisms using DNA extracted from FFPE material. By using the MassARRAY iPLEX system, we investigated polymorphisms in DPYD (rs1801159 and rs3918290), UMPS (rs1801019), ERCC1 (rs11615), ERCC1 (rs3212986), and ERCC2 (rs13181) in 56 FFPE DNA samples. By using PCR, followed by size-based gel electrophoresis, we also examined TYMS 5′ untranslated region 2R/3R repeats and GSTT1 deletions in 50 FFPE DNA samples and 34 DNAs extracted from fresh-frozen tissues and cell lines. Each polymorphism was analyzed by two independent runs. We found that iPLEX biomarker assays measuring single-nucleotide polymorphisms provided consistent concordant results. However, by using FFPE DNA, size-based PCR biomarkers (GSTT1 and TYMS 5′ untranslated region) were discrepant in 32.7% (16/49, with exact 95% CI, 19.9%–47.5%; exact binomial confidence limit test) and 4.2% (2/48, with exact 95% CI, 0.5%–14.3%) of cases, respectively, whereas no discrepancies were observed using intact genomic DNA. Our findings suggest that DNA from FFPE material can be used to reliably test single-nucleotide polymorphisms. However, results based on size-based PCR biomarkers, and particularly GSTT1 deletions, using FFPE DNA need to be interpreted with caution. Independent repeated assays should be performed on all cases to assess potential discrepancies. PMID:25746798

    Kellogg was requested by DOE/GRI to perform a technical and economic assessment of the Westinghouse fluidized bed coal gasification process as applied to production of SNG equivalent to 250 billion BTU/day from Pittsburgh No. 8 coal. Based on operating experiences in the PDU, where most of the key variables have been demonstrated during 5+ years of testing, Westinghouse provided process data for the gasifier area. Kellogg selected the overall processing sequence and established design bases for the balance of the plant. This work was subsequent to a previous (1979) screening evaluation of Westinghouse by Kellogg: comparison of the two designs reveals the following: The 1980 gasifier design basis, while more detailed, is almost identical to that of 1979. The gas treatment and sulfur recovery schemes were significantly changed: Combined shift/methanation was substituted for stand-alone reaction units; independent Selexol units for removal of H/sub 2/S and CO/sub 2/ replaced a non-selective Benfield unit; and a Claus-SCOT combination replaced Stretford units and significantly improved the flue gas desulfurization. Key results of the current efforts are compared with those of the screening evaluation. The reductions in efficiencies in the new calculations are attributed to a more realistic evaluation of plant energy requirements and to lack of optimization of individual plant section designs. The economic data indicate that a noteworthy reduction in gas cost was accomplished by a reduction in the capital cost of the plant, such that Kellogg concludes, as previously for the screening evaluation, that the Westinghouse process appears to be superior to existing processes (i.e., Lurgi) and at least competitive with other processes evaluated under the DOE/GRI joint program.

    The Stratton Ridge salt dome is a large salt diapir located only some ten miles from the currently active Strategic Petroleum Reserve Site at Bryan Mound, Texas. The dome is approximately 15 miles south-southwest of Houston. The Stratton Ridge salt dome has been intensively developed, in the desirable central portions, with caverns for both brine production and product storage. This geologic technical assessment indicates that the Stratton Ridge salt dome may be considered a viable, if less-than-desirable, candidate site for potential expansion of the Strategic Petroleum Reserve (SPR). Past development of underground caverns significantly limits the potential options for use by the SPR. The current conceptual design layout of proposed caverns for such an expansion facility is based upon a decades-old model of salt geometry, and it is unacceptable, according to this reinterpretation of salt dome geology. The easternmost set of conceptual caverns are located within a 300-ft buffer zone of a very major boundary shear zone, fault, or other structural feature of indeterminate origin. This structure transects the salt stock and subdivides it into an shallow western part and a deeper eastern part. In places, the distance from this structural boundary to the design-basis caverns is as little as 150 ft. A 300-ft distance from this boundary is likely to be the minimum acceptable stand-off, from both a geologic and a regulatory perspective. Repositioning of the proposed cavern field is possible, as sufficient currently undeveloped salt acreage appears to be available. However, such reconfiguration would be subject to limitations related to land-parcel boundaries and other existing infrastructure and topographic constraints. More broadly speaking, the past history of cavern operations at the Stratton Ridge salt dome indicates that operation of potential SPR expansion caverns at this site may be difficult, and correspondingly expensive.

  8. Technical and economic assessments of storage techniques for long-term retention of industrial-beet sugar for non-food industrial fermentations

    NASA Astrophysics Data System (ADS)

    Vargas-Ramirez, Juan Manuel

    Industrial beets may compete against corn grain as an important source of sugars for non-food industrial fermentations. However, dependable and energy-efficient systems for beet sugar storage and processing are necessary to help establish industrial beets as a viable sugar feedstock. Therefore, technical and economic aspects of beet sugar storage and processing were evaluated. First, sugar retention was evaluated in whole beets treated externally with either one of two antimicrobials or a senescence inhibitor and stored for 36 wk at different temperature and atmosphere combinations. Although surface treatment did not improve sugar retention, full retention was enabled by beet dehydration caused by ambient air at 25 °C and with a relative humidity of 37%. This insight led to the evaluation of sugar retention in ground-beet tissue ensiled for 8 wk at different combinations of acidic pH, moisture content (MC), and sugar:solids. Some combinations of pH ≤ 4.0 and MC ≤ 67.5% enabled retentions of at least 90%. Yeast fermentability was also evaluated in non-purified beet juice acidified to enable long-term storage and partially neutralized before fermentation. None of the salts synthesized through juice acidification and partial neutralization inhibited yeast fermentation at the levels evaluated in that work. Conversely, yeast fermentation rates significantly improved in the presence of ammonium salts, which appeared to compensate for nitrogen deficiencies. Capital and operating costs for production and storage of concentrated beet juice for an ethanol plant with a production capacity of 76 x 106 L y-1 were estimated on a dry-sugar basis as U.S. ¢34.0 kg-1 and ¢2.2 kg-1, respectively. Storage and processing techniques evaluated thus far prove that industrial beets are a technically-feasible sugar feedstock for ethanol production.

    The internal dosimetry program at the Savannah River Site (SRS) consists of radiation protection programs and activities used to detect and evaluate intakes of radioactive material by radiation workers. Examples of such programs are: air monitoring; surface contamination monitoring; personal contamination surveys; radiobioassay; and dose assessment. The objectives of the internal dosimetry program are to demonstrate that the workplace is under control and that workers are not being exposed to radioactive material, and to detect and assess inadvertent intakes in the workplace. The Savannah River Site Internal Dosimetry Technical Basis Manual (TBM) is intended to provide a technical and philosophical discussion of the radiobioassay and dose assessment aspects of the internal dosimetry program. Detailed information on air, surface, and personal contamination surveillance programs is not given in this manual except for how these programs interface with routine and special bioassay programs.

    The purpose of this addendum is, first, to provide and discuss disease agent survey results that were not available for inclusion in the Disease Risk Assessment portion of the YEAR 3 report at the time of its writing, and second, to make recommendations stemming from these results. The first set of results deals with live box exposure tests conducted using juvenile sentinel rainbow trout in the spring of 2002 to detect Myxosoma cerebralis and Ceratomyxa shasta. The second set of results deals with similar exposure tests conducted in the spring of 2003. The latter tests were initially intended to occur in the fall of 2002 but had to be re-scheduled to the spring of 2003 because suitably aged sentinel rainbow trout for the exposures were not available in the fall of 2002. The methods used for the live box exposure tests were essentially the same as those described in the YEAR 3 report. Fish were again exposed at the same four sites above McIntyre Dam and at the same four sites below the dam. As mentioned in the YEAR 3 report, the spring 2002 exposure lasted for 21 days (May 6 to 27). The spring 2003 exposure also lasted for 21 days (April 22 to May 13). The number of fish in the spring 2003 tests was, however, reduced to approximately half the number used in previous tests in order to reduce the chances of dissolved oxygen problems, suspected to have occurred in earlier tests in some of the live boxes. As before, fish that survived the live box exposures were transferred to Skaha Hatchery where they were held for sufficient time to permit any infections with M. cerebralis and C. shasta to develop and to permit for spore development in these pathogens. Assays for the pathogens were carried out as previously described. Detection of M. cerebralis was based on detecting its spores following the trypsin/pepsin digestion method. Detection of C. shasta was based on a polymerase chain reaction (PCR) test, but smears of fresh intestinal tissues (one fish per smear) were also

  6. [A comparative and technical assessment of the HELP system (heparin extracorporeal LDL precipitation) and cascade filtration (CF) for the treatment of high plasma lipids].

    PubMed

    Loschiavo, Carmelo

    2013-01-01

    Extracorporeal techniques for the removal of plasma lipids, known as LDL-apheresis, have improved treatment of atherosclerotic lesions in patients with familial hyperlipidemia (FH). In the homozygous form, such treatment is to be considered a life-saving therapy, and in heterozygous forms, which are widely distributed in the population, it is also used when there is a high risk of coronary atherogenic lesions and where a dietary and pharmacological approach has failed to satisfy the objective of a LDL-C 2.6 mmol/L. Of the various techniques available, we believe that cascade filtration (CF) and extracorporeal LDL precipitation with heparin (HELP) are the methods of choice for technical reasons, clinical efficacy and safety. HELP provides, at long-term follow-up, a 5% greater decrease in LDL-C and Lp (a) compared to CF, and about 10% increase in fibrinogen removal resulting in decreased blood viscosity. Conversely, CF produces a concomitant elimination of up to 20% of HDL-C, whereas HELP results in around 5% elimination. CF determines a loss of protein which over time can impact negatively on the protein profile, while HELP results in negligible protein loss. Finally, a significant dampening effect on the intermediate products of inflammation, which initiate the process of vessel atheroma development, has been documented only with HELP. Therefore, the HELP procedure appears to inhibit the development of atheromatous plaques via several different routes. PMID:23832475

    Acute respiratory infections are the leading cause of global child mortality. In the developing world, nasal oxygen therapy is often the only treatment option for babies who are suffering from respiratory distress. Without the added pressure of bubble Continuous Positive Airway Pressure (bCPAP) which helps maintain alveoli open, babies struggle to breathe and can suffer serious complications, and frequently death. A stand-alone bCPAP device can cost $6,000, too expensive for most developing world hospitals. Here, we describe the design and technical evaluation of a new, rugged bCPAP system that can be made in small volume for a cost-of-goods of approximately $350. Moreover, because of its simple design—consumer-grade pumps, medical tubing, and regulators—it requires only the simple replacement of a <$1 diaphragm approximately every 2 years for maintenance. The low-cost bCPAP device delivers pressure and flow equivalent to those of a reference bCPAP system used in the developed world. We describe the initial clinical cases of a child with bronchiolitis and a neonate with respiratory distress who were treated successfully with the new bCPAP device. PMID:23372661

    This report documents the results of a collaborative project to demonstrate a solid state lighting (SSL) general illumination product in an outdoor area walkway application. In the project, six light-emitting diode (LED) luminaires were installed to replace six existing high pressure sodium (HPS) luminaires mounted on 14-foot poles on a set of exterior walkways and stairs at the Federal Aviation Administration (FAA) William J. Hughes Technical Center in Atlantic City, New Jersey, during December, 2007. The effort was a U.S. Department of Energy (DOE) SSL Technology Gateway Demonstration that involved a collaborative teaming agreement between DOE, FAA and Ruud Lighting (and their wholly owned division, Beta LED). Pre- and post-installation power and illumination measurements were taken and used in calculations of energy savings and related economic payback, while personnel impacted by the new lights were provided questionnaires to gauge their perceptions and feedback. The SSL product demonstrated energy savings of over 25% while maintaining illuminance levels and improving illuminance uniformity. PNNL's economic analysis yielded a variety of potential payback results depending on the assumptions used. In the best case, replacing HPS with the LED luminaire can yield a payback as low as 3 years. The new lamps were quite popular with the affected personnel, who gave the lighting an average score of 4.46 out of 5 for improvement.

    The study addresses the possible ways of involving gaseous products produced by "wet" incineration of human wastes mixed with H2O2 in an alternating electric field in the cycling of the physical model of a bio-technical life support system (BTLSS). The resulting gas mixture contains CO2 and O2, which are easily involved in the cycling in the closed ecosystem, and NH3, which is unacceptable in the atmosphere of the BTLSS. NH3 fixation has been proposed, which is followed by nitrification and involvement of the resulting products in the mass exchange of the closed system. Experiments have been performed to show that plants can be grown in the atmosphere resulting from the closing of the gas loop that includes a physicochemical installation and a growth chamber with plants representing the phototrophic compartment of the BTLSS. The results of the study suggest the conclusion that the proposed method of organic waste oxidation can be a useful tool in creating a physical model of a closed-loop integrated BTLSS.

    Under Title III, Section 313 of the Superfund Amendment and Reauthorization Act of 1986 (SARA) companies which release toxic chemicals into the environment are required to report annually the amount of these toxic releases. Because the chemical toxic-release reports are public information, EPA Region V is concerned that the raw data published in the toxic-chemical-release reports will be misinterpreted and will in turn generate unfounded public concern. The study examines the possibility of using the Graphical Exposure Modeling System (GEMS), a computer program, to transform incoming raw data into better qualified, user ready, public information. Specifically, the report analyzes the compatibility between the raw data reported in the toxic chemical release reports and the input requirements of the GEMS exposure model. An industrial site in East St. Louis, Illinois is used as a test site for the development of the exposure assessment. The study discusses the research and the methods used to perform the exposure assessment. The report also reviews the legislation which requires companies to report toxic-release data, the basics of exposure assessment and the GEMS model, the research methods used, and the findings of the study.

    2015-08-01

    Acute puerperal metritis (APM) in dairy cows is a common disease occurring in the first 10 d after calving. According to a widely accepted definition, the diagnosis is primarily based on body temperature and sensorial assessment of vaginal discharge. The scope of this study was to evaluate the reliability for color, smell, and viscosity of vaginal discharge from healthy cows and cows with APM. Fifteen investigators evaluated 6 vaginal discharge samples 10 times. Subsequently, the investigators rated the health status of the cows and the diagnostic value of color, smell, and viscosity. In a final questionnaire, the investigators estimated their ability to diagnose APM correctly and the influence of experience. Reliability was tested using Cohen's kappa (κ). Our study revealed slight to moderate reliabilities concerning the assessment of vaginal discharge. Overall interobserver reliability for color, smell, and viscosity was κ=0.15, 0.27, and 0.44, respectively. Overall intraobserver reliability for color, smell, and viscosity was κ=0.35, 0.39, and 0.6, respectively. By means of a questionnaire, overall personal expertise to detect cows suffering from APM correctly as such was estimated to be 59%, whereas the diagnostic value of a combination of color, smell, and viscosity to detect cows with APM correctly was estimated to be 91.1% perfect. We found a discrepancy between reliability and the personal perception of diagnostic value. Our study shows that the sensorial assessment of color, smell, and viscosity of vaginal discharge in cows postpartum is subjective. PMID:26026759

    The Industrial Assessment Center program at North Carolina State University has conducted one hundred industrial assessments of small and medium sized manufacturers in North Carolina, South Carolina, and Virginia. Reports were submitted to each facility that included a brief description of the plant, historical energy use, and a technical analysis of potential energy efficiency savings, waste reduction, and productivity savings. Seven hundred thirty eight conservation measures were recommended with total annual cost savings in excess of $18 million. The NCSU IAC has worked with other government and private entities to deliver energy efficiency and conservation services. We have worked closely with the NCSU Industrial Extension Service, the Manufacturer’s Extension Partnership (MEP), and the North Carolina State Energy Office to provide follow-up technical help and financial assistance in implementing conservation recommendations. In addition to these organizations, the NCSU IAC has also worked with the NC Department of Pollution Prevention and Environmental Assistance, the NC Solar Center, Advanced Energy Corporation, Duke Power, Progress Energy, Dominion Power, and the City of Danville, Virginia. Eighteen undergraduate and twenty graduate students were exposed to a variety of manufacturing processes, trained on plant safety, and taught the use of various types of data collection equipment. The students performed technical analyses of each recommendation, computed the potential savings from engineering relations and collected data, estimated the cost from vendor information, and communicated the findings in a compact, well written report to the client. The students have also been exposed to a variety of business personnel, including corporate presidents, engineering managers, plant managers, plant engineers, facility maintenance staff, and production workers – each with a unique perspective on the challenges faced in a modern manufacturing facility.

  17. Applying the European protocol for the quality control of the physical and technical aspects of mammography screening threshold contrast visibility assessment to digital systems

    NASA Astrophysics Data System (ADS)

    Van Metter, Richard; Heath, Michael; Fletcher-Heath, Lynn

    2006-03-01

    The need to assure the image quality of digital systems for mammography screening applications is now widely recognized. One approach is embodied in Part B of the European Protocol for the Quality Control of the Physical and Technical Aspects of Mammography Screening (EPQCM), which prescribes criteria for several interconnected image quality metrics. The focus of this study is on the "threshold contrast visibility" (TCV) protocol (section 2.4.1 of the EPQCM), in which human observers score images of a CDMAM or similar 4-AFC phantom. This section of the EPQCM currently omits many critical experimental details, which must be gleaned from ancillary documents. Given these, the purpose of this study is to quantify the effects of several remaining experimental variables, including phantom design, and the methods used for scoring and analysis, on the measured results. Preliminary studies of two CDMAM version 3.4 (CDMAM 3.4) phantoms have revealed a 17% difference in TCV when averaged over all target diameters from 0.1 to 2.0 mm. This indicates phantom variability may affect results at some sites. More importantly, we have shown that the current CDMAM phantom design, methods for scoring, and analysis, substantially limit the ability to measure system performance accurately and precisely. An improved phantom design has been shown to avoid these limitations. Viewing environment and presentation context affect the performance and efficiency of visual scoring of phantom images. An automated display tool has been developed that isolates individual 4-AFC targets of CDMAM phantom images, automatically optimizes window/level, and automatically records observers' scores. While not substantially changing TCV, the tool has increased scoring efficiency while mitigating several of the limitations associated with unassisted visual scoring. For example, learning bias and navigational issues are completely avoided. Ultimately, software-based ideal observer scoring will likely prove to be

    The aim of this study was to compare automated ribosomal intergenic spacer analysis (ARISA) and denaturing gradient gel electrophoresis (DGGE) techniques to assess bacterial diversity in the rumen of sheep. Sheep were fed 2 diets with 70% of either alfalfa hay or grass hay, and the solid (SOL) and liquid (LIQ) phases of the rumen were sampled immediately before feeding (0 h) and at 4 and 8 h postfeeding. Both techniques detected similar differences between forages, with alfalfa hay promoting greater (P < 0.05) bacterial diversity than grass hay. In contrast, whereas ARISA analysis showed a decrease (P < 0.05) of bacterial diversity in SOL at 4 h postfeeding compared with 0 and 8 h samplings, no variations (P > 0.05) over the postfeeding period were detected by DGGE. The ARISA technique showed lower (P < 0.05) bacterial diversity in SOL than in LIQ samples at 4 h postfeeding, but no differences (P > 0.05) in bacterial diversity between both rumen phases were detected by DGGE. Under the conditions of this study, the DGGE was not sensitive enough to detect some changes in ruminal bacterial communities, and therefore ARISA was considered more accurate for assessing bacterial diversity of ruminal samples. The results highlight the influence of the fingerprinting technique used to draw conclusions on factors affecting ruminal bacterial diversity. PMID:24492564

    The purpose of this paper is: (1) conduct HELP model variations in weather data, profile characteristics, and hydraulic conductivities for major rock units; (2) compare and contrast the results of simulations; (3) obtain an estimation of leakage through the landfill from the surface to the aquifer; and (4) evaluate contaminant transport to the aquifer utilizing leakage estimation. The conclusions of this paper are: (1) the HELP model is useful to assess landfill design alternatives or the performance of a pre-existing landfill; (2) model results using site-specific data incorporated into the Weather Generator (Trail 4), varied significantly from generalized runs (Trials 1-3), consequently, models that lack site-specific data should be used cautiously; and (3) data from this study suggest that there will not be significant downward percolation of leachate from the surface of the landfill cap to the aquifer-leachate transport rates have been calculated to be slow.

    Elite overhead athletes are at risk of vascular injury due to repetitive abduction and external rotation of the dominant arm. The posterior circumflex humeral artery (PCHA) is prone to degeneration, aneurysm formation, and thrombosis in elite volleyball players and baseball pitchers. The prevalence of PCHA-related thromboembolic complications is unknown in this population. However, the prevalence of symptoms associated with digital ischemia is 31% in elite volleyball players. A standardized noninvasive imaging tool will aid in early detection of PCHA injury, prevention of thromboembolic complications, and measurement reproducibility. A standardized vascular sonographic protocol for assessment of the proximal PCHA (SPI-US protocol [Shoulder PCHA Pathology and Digital Ischemia-Ultrasound protocol]) is presented. PMID:27072158

    WHO Technical Report 921 "Prevention and Management of Osteoporosis" was published in 2003. WHO Scientific Group Meeting on Prevention and Management of Osteoporosis was organized in 1998. The members consisted of 21 scientists from all over the world with 2 experts in WHO. Contents of the book included introduction, pathogenesis of osteoporosis and related fractures, epidemiology and risk factors, diagnosis and assessment, prevention and treatment, socioeconomic aspects, delivery of care and education, summary and recommendations. Osteoporosis is a silent epidemic and destroys QOL in overwhelming populations in the world. Risk factors are different from country to country, but nutritional, genetic, life style and other factors are concerned in the pathogenesis of the disease. Appropriate assessment and diagnosis are essential for the evaluation who should be treated. Many kinds of drugs have been developed for the treatment. Many ways for treating patients with fractures have been proposed. However, the establishment of systems of care is needed with aids of both governmental and non-governmental organizations. Finally education of citizens is very important. PMID:15802765

  8. A TECHNICAL ASSESSMENT OF THE CURRENT WATER POLICY BOUNDARY AT U.S. DEPARTMENT OF ENERGY, PADUCAH GASEOUS DIFFUSION PLANT, PADUCAH, KENTUCKY

    In 1988, groundwater contaminated with trichloroethene (TCE) and technetium-99 (Tc-99) was identified in samples collected from residential water wells withdrawing groundwater from the Regional Gravel Aquifer (RGA) north of the Paducah Gaseous Diffusion Plant (PGDP) facility. In response, the U.S. Department of Energy (DOE) provided temporary drinking water supplies to approximately 100 potentially affected residents by initially supplying bottled water, water tanks, and water-treatment systems, and then by extending municipal water lines, all at no cost, to those persons whose wells could be affected by contaminated groundwater. The Water Policy boundary was established in 1993. In the Policy, DOE agreed to pay the reasonable monthly cost of water for homes and businesses and, in exchange, many of the land owners signed license agreements committing to cease using the groundwater via rural water wells. In 2012, DOE requested that Oak Ridge Associated Universities (ORAU), managing contractor of Oak Ridge Institute for Science and Education (ORISE), provide an independent assessment of the quality and quantity of the existing groundwater monitoring data and determine if there is sufficient information to support a modification to the boundary of the current Water Policy. As a result of the assessment, ORAU concludes that sufficient groundwater monitoring data exists to determine that a shrinkage and/or shift of the plume(s) responsible for the initial development of this policy has occurred. Specifically, there is compelling evidence that the TCE plume is undergoing shrinkage due to natural attenuation and associated degradation. The plume shrinkage (and migration) has also been augmented in local areas where large volumes of groundwater were recovered by pump-and treat remedial systems along the eastern and western boundaries of the Northwest Plume, and in other areas where pump-and-treat systems have been deployed by DOE to remove source contaminants.

    This report presents data and assumptions employed in an application of PNNL’s Global Change Assessment Model with a newly-developed Monte Carlo analysis capability. The model is used to analyze the impacts of more aggressive U.S. residential and commercial building-energy codes and equipment standards on energy consumption and energy service costs at the state level, explicitly recognizing uncertainty in technology effectiveness and cost, socioeconomics, presence or absence of carbon prices, and climate impacts on energy demand. The report provides a summary of how residential and commercial buildings are modeled, together with assumptions made for the distributions of state–level population, Gross Domestic Product (GDP) per worker, efficiency and cost of residential and commercial energy equipment by end use, and efficiency and cost of residential and commercial building shells. The cost and performance of equipment and of building shells are reported separately for current building and equipment efficiency standards and for more aggressive standards. The report also details assumptions concerning future improvements brought about by projected trends in technology.

    A Sampling and Analysis Plan was prepared and submitted to a Scientific Review Committee for comment. Substantial comments relative to study objectives, sampling design, and sampling periods coupled with the passage of Hurricane Andrew precluded the scheduled initiation of sampling at offshore and coastal sites (Tasks 3 -- Environmental Field Sampling and Analysis of Naturally Occurring Radioactive Materials (NORM), Heavy Metals, and Organics and 4 -- Monitoring of the Recovery of Impacted Wetland and Open Bay Produced Water Discharge Sites in Coastal Louisiana and Texas). A proposed revised schedule has been prepared for Tasks 3 and 4. Task 5 (Assessment of Economic Impacts of Offshore and Coastal Discharge Requirements on Present and Future Operations in the Gulf of Mexico Region), activities have involved identification and collection of the necessary data for the economic analysis. Task 6 (Synthesis of Gulf of Mexico Region Consumption and Use Patterns), activities have included near completion of the literature review and a reevaluation of the data collection efforts relative to the wholesaler, process plant, and restaurant components. Task 7 (Technology Transfer Plan), work has been delayed due to the Tasks 3 and 4 delay and cancellation of the annual US Minerals Management Service Gulf of Mexico Region Information Transfer Meeting.

    The overall objective of this research project was to explore the use of in situ bIomonitoring using wild mammalian animal models to assess ecotoxicity risks from petrochemical contaminants. We approached this objective by comparing the relative sensitivities of selected measures of metabolic, immunologic, genetic, and histopathologic toxicity (multiparameter model) in small-mammalian residents of terrestrial ecosystems contaminated with complex mixtures of petrochemicals (an abandoned oil refinery complex). Multiparameter response profiles of small mammals were evaluated relative to results from common laboratory bioassay tests (fathead minnow survival, rice seed germination test, etc.) and soil chemical analyses to determine their ability to predict ecotoxicity risks (as indexed by demographic changes in the small mammal community). Our principal in situ biomonitor was the cotton rat (Sigmodon hispidus), which is the dominant member of the small mammal community on 3 uncontaminated reference and 3 heavy metal-petrochemical contaminated study sites. Chemical analyses of soil and soil extracts identified a variety of heavy metal and organic contaminants on the 3 suspected toxic study sites, which was reflected in common laboratory bioassay results using fathead minnow, microtox, rice seed germination, and Ceriodaphnia assays.

    This volume describes emission results from sampling of flue-gas from a firetube boiler burning a coal/oil/water (COW) mixture and COW with soda ash added (COW+SA) to control SO/sub 2/ emissions. Measurements included: continuous monitoring of flue-gas emissions; source assessment sampling system (SASS) sampling of the flue gas with subsequent laboratory analysis of the samples to give total flue gas organics in two boiling point ranges, specific quantitation of the semivolatile organic priority pollutant species, and flue gas concentrations of 73 trace elements; Method 5 sampling for total particulate; and controlled condensation system sampling for SO/sub 2/ and SO/sub 3/ emissions. Flue-gas SO/sub 2/ emissions decreased almost 99% with soda ash addition from 1,089 to 13.6 ppm (3% O2). NOx emissions decreased slightly from 477 to 427 ppm, while CO emissions increased significantly from an average of 25 to 426 ppm (all at 3% O2). Particulate loading at the boiler outlet almost doubled (from 1,970 to 3,715 pg/dscm) with the additive. The size distribution of particulate also shifted to a much smaller mean diameter. Total organic emissions increased from 6.7 to 13.1 mg/dscm; most of the increase were nonvolatile (C16+) organics. Of the semivolatile organic priority pollutant species, only fluoranthene and phenanthrene were detected with the COW fuel, and phenanthrene with the COW+SA fuel.

    The non-technical skills of situational awareness and the formation of effective interpersonal relationships are essential to enhance surgical outcomes. However, most scrub practitioners demonstrate only tacit awareness of these skills and develop such qualities on an informal basis. Application of non-technical skills may be assessed formally, using a structured framework, to transform normative behaviour and to strengthen barriers against the latent threats that may result from fallible humans working in inadequate organisational systems.

    for future habitat restoration actions. Such designs are being developed concurrently with this project by several other groups in the Columbia Basin (RME Workgroup 2003, NMFS 2003, Hillman and Paulsen 2002, Hillman 2003). By addressing questions about habitat restoration and monitoring (in coordination with other related efforts), we hope that this project will catalyze a shift in the Basin's paradigm of habitat restoration, moving from implementation of individual watershed projects towards rigorously designed and monitored, multiwatershed, adaptive management experiments. The project involved three phases of work, which were closely integrated with various related and ongoing efforts in the region: (1) Scoping - We met with a Core Group of habitat experts and managers to scope out a set of testable habitat restoration hypotheses, identify candidate watersheds and recommend participants for a data evaluation workshop. (2) Data Assembly - We contacted over 80 scientists and managers to help evaluate the suitability of each candidate watershed's historical data for assessing the effectiveness of past restoration actions. We eventually settled on the Yakima, Wenatchee, Clearwater, and Salmon subbasins, and began gathering relevant data for these watersheds at a workshop with habitat experts and managers. Data assembly continued for several months after the workshop. (3) Data Analysis and Synthesis - We explored statistical approaches towards retrospectively analyzing the effects of restoration 'treatments' at nested spatial scales across multiple watersheds (Chapters 2-5 of this report). These analyses provided a foundation for identifying existing constraints to testing restoration hypotheses, and opportunities to overcome these constraints through improved experimental designs, monitoring protocols and project selection strategies (Chapters 6 and 7 of this report). Finally, we developed a set of recommendations to improve the design, implementation, and monitoring of
