    Achieving the Advanced Turbine Systems (ATS) goals of 60% efficiency, single-digit NO{sub x}, and 10% electric power cost reduction imposes competing characteristics on the gas turbine system. Two basic technical issues arise from this. The turbine inlet temperature of the gas turbine must increase to achieve both efficiency and cost goals. However, higher temperatures move in the direction of increased NO{sub x} emission. Improved coatings and materials technologies along with creative combustor design can result in solutions to achieve the ultimate goal. GE`s view of the market, in conjunction with the industrial and utility objectives, requires the development of Advanced Gas Turbine Systems which encompass two potential products: a new aeroderivative combined-cycle system for the industrial market, and a combined-cycle system for the utility sector that is based on an advanced frame machine. The GE Advanced Gas Turbine Development program is focused on two specific products: (1) a 70 MW class industrial gas turbine based on the GE90 core technology utilizing an innovative air cooling methodology; (2) a 200 MW class utility gas turbine based on an advanced Ge heavy-duty machine utilizing advanced cooling and enhancement in component efficiency. Both of these activities required the identification and resolution of technical issues critical to achieving ATS goals. The emphasis for the industrial ATS was placed upon innovative cycle design and low emission combustion. The emphasis for the utility ATS was placed on developing a technology base for advanced turbine cooling, while utilizing demonstrated and planned improvements in low emission combustion. Significant overlap in the development programs will allow common technologies to be applied to both products. GE Power Systems is solely responsible for offering GE products for the industrial and utility markets.

    We describe the conceptualization and development of the Behavior Analysis programs at the Florida Institute of Technology (Florida Tech). From its beginnings as a small master's program in applied behavior analysis (ABA), the Behavior Analysis programs at Florida Tech have now grown to include three Master of Science programs across two campuses, a Ph.D. program in Behavior Analysis, an undergraduate degree (B.A.) in ABA, an online certificate program that has attracted students internationally, and a hybrid (live and online) Master of Arts in Professional Behavior Analysis program at several sites around the USA. These programs are now housed in the first ever School of Behavior Analysis at a Tier 1, nationally ranked private university. PMID:27606195

    This work looks into the meanings of nursing from the point of view of the students in an undergraduate nursing degree program. The research took place at the Universidad Nacional de Lanús using semistructured interviews - eleven individual and seven group interviews - carried out between 2008 and 2010. A content analysis was then undertaken and the most relevant meanings in relation to four themes were selected: reasons for studying nursing, what nursing is, nursing as a profession, and working in nursing. Multiple and diverse ways of defining nursing were uncovered. Utilizing some conceptual developments from the sociology of the professions, the meanings were organized into four conceptualizations that represent ways of understanding nursing: as a vocation, as a profession, with a utilitarian perspective and with a community perspective. The conclusions reached indicate the need to broaden the debate regarding the types of nurses that are being trained.

    This article argues for the existence of persistent conceptual "bugs" in how novices program and understand programs. These bugs are not specific to a given programming language, but appear to be language-independent. Furthermore, such bugs occur for novices from primary school to college age. Three different classes of bugs-parallelism, intentionality, and egocentrism - are identified, and exemplified through student errors. It is suggested that these classes of conceptual bugs are rooted in...

    . Considering the strength and limitations of both methodologies, the question to be answered in this thesis is: How valuable and compatible are the classical analytical methods in today's conceptual design environment? And can these methods complement each other? To answer these questions, this thesis investigates the pros and cons of classical analytical structural analysis methods during the conceptual design stage through the following objectives: Illustrate structural design methodology of these methods within the framework of Aerospace Vehicle Design (AVD) lab's design lifecycle. Demonstrate the effectiveness of moment distribution method through four case studies. This will be done by considering and evaluating the strength and limitation of these methods. In order to objectively quantify the limitation and capabilities of the analytical method at the conceptual design stage, each case study becomes more complex than the one before.

    Goal 9 of the LANL FY15 Site Sustainability Plan (LANL 2014a) addresses Climate Change Adaptation. As part of Goal 9, the plan reviews many of the individual programs the Laboratory has initiated over the past 20 years to address climate change impacts to LANL (e.g. Wildland Fire Management Plan, Forest Management Plan, etc.). However, at that time, LANL did not yet have a comprehensive approach to climate change adaptation. To fill this gap, the FY15 Work Plan for the LANL Long Term Strategy for Environmental Stewardship and Sustainability (LANL 2015) included a goal of (1) establishing a comprehensive conceptual model of climate change impacts at LANL and (2) establishing specific climate change indices to measure climate change and impacts at Los Alamos. Establishing a conceptual model of climate change impacts will demonstrate that the Laboratory is addressing climate change impacts in a comprehensive manner. This paper fulfills the requirement of goal 1. The establishment of specific indices of climate change at Los Alamos (goal 2), will improve our ability to determine climate change vulnerabilities and assess risk. Future work will include prioritizing risks, evaluating options/technologies/costs, and where appropriate, taking actions. To develop a comprehensive conceptual model of climate change impacts, we selected the framework provided in the National Oceanic and Atmospheric Administration (NOAA) Climate Resilience Toolkit (http://toolkit.climate.gov/).

  12. Conceptual tokamak design at high neutron fluence

    International Nuclear Information System (INIS)

    For the future fusion reactor, it is important to design an experimental device that can be performed testing in-vessel components including tritium breeding modules relevant to the future fusion reactor with high neutron fluence. To realize this requirement, a conceptual tokamak design has been performed in accordance with plasma performance and shape at quasi-steady-state operation. One of the promising scenarios for this purpose is proposed to produce the plasma at the outward shifted radial position with a small minor radius for reasonable plasma parameters. From the analytical results, an appropriate space can be found for neutron shielding so that additional neutron shielding can be installed to protect the tokamak components from any neutron damages under the neutron fluence of 1 MWa m-2. Based on the structural analyses, a two-stage blanket module concept is proposed, i.e. one shielding block with the first wall assembly during high Q operation and two shielding blocks or additional tritium breeding modules during quasi-steady state operation

    2011-03-01

    Our objective was to evaluate whether the limited effectiveness of most community programs intended to prevent disease and promote health should be attributed to the quality of the conceptualization of their program theories. In a retrospective multiple case study we assessed the program theories of 16 community programs (cases) in the Netherlands (1990-2004). Methods were a document analysis, supplemented with member checks (insider information from representatives). We developed a community approach reference framework to guide us in reconstructing and evaluating the program theories. On the whole, programs did not clearly spell out the process theories (enabling the implementation of effective interventions), the program components (interventions) and/or the impact theories (describing pathways from interventions to ultimate effects). Program theories usually turned out to be neither specific nor entirely plausible (complete and valid). The limited effectiveness of most community programs should most probably be attributed to the limited conceptualization of program theories to begin with. Such a failure generally also precludes a thorough examination of the effectiveness of the community approach as such.

    The U.S. Department of Energy (DOE) faces many decisions regarding future remedial actions and waste disposal at the Hanford Site in southeast Washington State. To support these decisions, DOE recognized the need for a comprehensive and systematic approach to developing and documenting complete, consistent, and defensible conceptual models of contaminant release and migration. After reviewing existing conceptual model development methodologies that might be applicable to environmental assessments at the Hanford Site, DOE initiated efforts to adapt and implement the Features, Events, and Processes (FEP) methodology developed for use in performance assessments of nuclear waste disposal systems by NIREX. In adapting this methodology for use in the environmental assessments at Hanford, the international list of FEPs, compiled from nuclear waste disposal programs, was evaluated to develop a list of potentially relevant Hanford-specific FEPs. The international nuclear waste programs focus on deep geologic disposal while waste disposal at the Hanford Site involves burial in shallow unconsolidated geologic deposits. Thus, a graphical tool called the Process Relationship Diagram (PRD) was created to assist in identifying the international FEPs and additional factors that are relevant to Hanford, and to illustrate the relationships among these factors. The PRD is similar in form and function to the Master Directed Diagram used by NIREX to provide a visual and systematic structure for the FEP methodology. Adaptation of this approach is showing promise in facilitating the development of conceptual models and selection of relevant factors to be incorporated into environmental uncertainty assessments for the Hanford Site.

As allowed by the Contract (Part 3, Section J, Attachment B) this report is also intended to fulfill the requirements for a fourth quarterly report. The objective of Phase 2 of the ATS Program is to provide the conceptual design and product development plan for an ultra-high efficiency, environmentally superior and cost-competitive industrial gas turbine system to be commercialized in the year 2000. During the period covered by this report, Solar has completed three of eight program tasks and has submitted topical reports. These three tasks included a Project Plan submission of information required by NEPA, and the selection of a Gas-Fueled Advanced Turbine System (GFATS). In the latest of the three tasks, Solar`s Engineering team identified an intercooled and recuperated (ICR) gas turbine as the eventual outcome of DOE`s ATS program coupled with Solar`s internal New Product Introduction (NPI) program. This machine, designated ``ATS50`` will operate at a thermal efficiency (turbine shaft power/fuel LHV) of 50 percent, will emit less than 10 parts per million of NOx and will reduce the cost of electricity by 10 percent. It will also demonstrate levels of reliability, availability, maintainability, and durability (RAMD) equal to or better than those of today`s gas turbine systems. Current activity is concentrated in three of the remaining five tasks a Market Study, GFATS System Definition and Analysis, and the Design and Test of Critical Components.

    Full Text Available A correct understanding about how computers run code is mandatory in order to effectively learn to program. Lectures have historically been used in programming courses to teach how computers execute code, and students are assessed through traditional evaluation methods, such as exams. Constructivism learning theory objects to students’ passiveness during lessons, and traditional quantitative methods for evaluating a complex cognitive process such as understanding. Constructivism proposes complimentary techniques, such as conceptual contraposition and colloquies. We enriched lectures of a “Programming II” (CS2 course combining conceptual contraposition with program memory tracing, then we evaluated students’ understanding of programming concepts through colloquies. Results revealed that these techniques applied to the lecture are insufficient to help students develop satisfactory mental models of the C++ notional machine, and colloquies behaved as the most comprehensive traditional evaluations conducted in the course.

    2006-11-01

    Violence against women has been a problem in human cultures for centuries. This is still the case both in developed and in developing countries, but it is in developing countries where the problem is aggravated as the result of cultural norms that are tolerant of men exerting power over women and girls as a commonly accepted practice. This power is often put into practice through physical and psychological acts of violence. In Mexico, as in many other countries, there is a legal framework that protects women from such acts, yet in the case of Mexico it has not yet been translated into actual improvements in their lives. We present an overview of advances in legal remedies regarding violence towards females internationally and in Mexico. The fact that these advances per se do not lead to changes in social norms that tolerate violence against females is emphasized. Also presented is the experience of the Mexican Institute for Research on Family and Population (IMIFAP) with the design and implementation of programs that promote protective factors and changes in behaviors in such a way that violence is effectively prevented. These programs focus on the development of psychosocial skills and knowledge through participatory workshops that promote self reflection, and they are developed and evaluated before being then applied on a large scale in poverty-stricken communities. These workshops lead to more egalitarian relationships between genders. IMIFAP's programs address not only violence but also other areas are integrated such that the enablement of psychosocial skills is applied in the broader socio-cultural context, leading to healthier and economically more productive lives. These programs are derived from the Framework for Enabling Agentic Empowerment (FENAE), which enables choice and the development of agentic empowerment through integrating skills, knowledge, and the context in which people live.

    Recent research suggests that school-based kindness education programs may benefit the learning and social-emotional development of youth and may improve school climate and school safety outcomes. However, how and to what extent kindness education programming influences positive outcomes in schools is poorly understood, and such programs are difficult to evaluate in the absence of a conceptual model for studying their effectiveness. In partnership with Kind Campus, a widely adopted school-based kindness education program that uses a bottom-up program framework, a methodology called concept mapping was used to develop a conceptual model for evaluating school-based kindness education programs from the input of 123 middle school students and approximately 150 educators, school professionals, and academic scholars. From the basis of this model, recommendations for processes and outcomes that would be useful to assess in evaluations of kindness education programs are made, and areas where additional instrument development may be necessary are highlighted. The utility of the concept mapping method as an initial step in evaluating other grassroots or non-traditional educational programming is also discussed. PMID:27376750

    Full Text Available Community mobilizing strategies are essential to health promotion and uptake of HIV prevention. However, there has been little conceptual work conducted to establish the core components of community mobilization, which are needed to guide HIV prevention programming and evaluation.We aimed to identify the key domains of community mobilization (CM essential to change health outcomes or behaviors, and to determine whether these hypothesized CM domains were relevant to a rural South African setting.We studied social movements and community capacity, empowerment and development literatures, assessing common elements needed to operationalize HIV programs at a community level. After synthesizing these elements into six essential CM domains, we explored the salience of these CM domains qualitatively, through analysis of 10 key informant in-depth-interviews and seven focus groups in three villages in Bushbuckridge.CM DOMAINS INCLUDE: 1 shared concerns, 2 critical consciousness, 3 organizational structures/networks, 4 leadership (individual and/or institutional, 5 collective activities/actions, and 6 social cohesion. Qualitative data indicated that the proposed domains tapped into theoretically consistent constructs comprising aspects of CM processes. Some domains, extracted from largely Western theory, required little adaptation for the South African context; others translated less effortlessly. For example, critical consciousness to collectively question and resolve community challenges functioned as expected. However, organizations/networks, while essential, operated differently than originally hypothesized - not through formal organizations, but through diffuse family networks.To date, few community mobilizing efforts in HIV prevention have clearly defined the meaning and domains of CM prior to intervention design. We distilled six CM domains from the literature; all were pertinent to mobilization in rural South Africa. While some adaptation of

    The purpose of this article was to illustrate the development of a team's research program based on a conceptual model for the nursing discipline: Roy's Adaptation Model. The ongoing research program includes studies of psychosocial factors, theoretically known for their potential for explaining health. Four groups of people are the focus of these studies: aged spouses in the community, family caregivers of ill elderly people, family caregivers of mentally ill people, and nurses as professional caregivers for elderly people in institutions. The studies are articulated using the three-level structure proposed by Fawcett & Downs (1986) and Fawcett (1991): conceptual-theoretical-empirical. This research program aims to renew understanding of the person's adaptation processes to various environmental stimuli, adaptive responses that influence health, and nursing interventions that promote health (i.e., biopsychosocial integrity). In order to specify the research variables and relations to be studied between these variables in the first phase of the program, each research project is also guided by a middle-range theory compatible with Roy's Adaptation Model. Elaborated within related disciplines, these theories are variations of the Stress and Coping theory of Lazarus & Folkman (1984). The results of these studies will be compared and articulated in a model that integrates the patterns of relations between the variables. The resulting empirical model together with Roy's conceptual model will be used to guide the development of nursing interventions intended to promote adaptive responses and biopsychosocial integrity. The second phase of the research program includes the implementation and evaluation of nursing strategies that promote adaptation among the four groups of people. This research program is a nursing contribution to certain social issues recognized as priorities by the governments of Canada and Québec. This article is an illustration of one of the various

    Full Text Available This paper traces the conceptual evolution of Architectural Program through the second half of the 20th century.  It discusses the evolution of the notion and its place in the architectural discourse in the works of various scholars, while giving and reviewing essential views, with a particular focus on two paradigmatic epistemological positions under which these views could be categorized: analysis-synthesis and conjecture-refutations. Aiming towards a reconsideration of the notion, it concludes with presenting our present understanding and conception of the notion, namely the present “state” of architectural program in the architectural agenda.

  12. Conceptual design report: below-grade bulk waste disposal facility. Formerly Utilized Sites Remedial Action Program

    International Nuclear Information System (INIS)

    This report presents two conceptual designs for below-grade land disposal facilities in the Northeastern United States for wastes managed under the Formerly Utilized Sites Remedial Action Program (FUSRAP). The wastes are low specific activity radioactive wastes generated by programs of the Manhattan Engineer District/Atomic Energy Commission (MED/AEC). One design presented is for a hypothetical disposal facility for the state of New York and one for the state of New Jersey. Each design is based on the estimated volume of FUSRAP waste in each state. Since no specific sites have been identified for the disposal facilities, the geologic, hydrologic, topographic, and meteorologic conditions chosen for the conceptual design are only representative of conditions in New York and New Jersey. The principal difference in the two sites is the assumed soil permeability which requires an engineered clay liner surrounding the waste for the New York facility, but not for the New Jersey facility. The conceptual designs are intended to be conservative and were developed to be compatible with proposed 10 CFR 61 and proposed 40 CFR 192. The designs are developed in sufficient detail to verify the feasibility of the design concepts and to provide a basis for developing capital cost estimates for below-grade land disposal facilities

  13. Nova program at LLNL

    International Nuclear Information System (INIS)

    At LLNL, successful experimental work is being performed with the Nova laser facility, a solid state laser system using neodymium-doped glass laser technology. Nova is the primary U.S. facility devoted to the study of the indirect drive approach to inertial fusion. In this concept, energy from a laboratory driver is converted to radiation that is used to implode and heat the fusion fuel in an inertial fusion capsule. Nova's principial objective is to demonstrate that laser-driven hohlraums (chambers that trap electromagnetic radiation) can meet the conditions of driver/target coupling efficiency, driver irradiation symmetry, driver pulse-shaping, target preheat, and hydrodynamic stability required by hot spot ignition and by fuel compression in order to realize net fusion gain (fusion energy released/driver energy delivered). Major results within the Nova Program fall within the areas of laser performance, target diagnostics, and implosion experiments. (author) 2 figs

  14. Facility for Advanced Accelerator Experimental Tests at SLAC (FACET) Conceptual Design Report

    Energy Technology Data Exchange (ETDEWEB)

    Amann, J.; Bane, K.; /SLAC

    2009-10-30

    This Conceptual Design Report (CDR) describes the design of FACET. It will be updated to stay current with the developing design of the facility. This CDR begins as the baseline conceptual design and will evolve into an 'as-built' manual for the completed facility. The Executive Summary, Chapter 1, gives an introduction to the FACET project and describes the salient features of its design. Chapter 2 gives an overview of FACET. It describes the general parameters of the machine and the basic approaches to implementation. The FACET project does not include the implementation of specific scientific experiments either for plasma wake-field acceleration for other applications. Nonetheless, enough work has been done to define potential experiments to assure that the facility can meet the requirements of the experimental community. Chapter 3, Scientific Case, describes the planned plasma wakefield and other experiments. Chapter 4, Technical Description of FACET, describes the parameters and design of all technical systems of FACET. FACET uses the first two thirds of the existing SLAC linac to accelerate the beam to about 20GeV, and compress it with the aid of two chicanes, located in Sector 10 and Sector 20. The Sector 20 area will include a focusing system, the generic experimental area and the beam dump. Chapter 5, Management of Scientific Program, describes the management of the scientific program at FACET. Chapter 6, Environment, Safety and Health and Quality Assurance, describes the existing programs at SLAC and their application to the FACET project. It includes a preliminary analysis of safety hazards and the planned mitigation. Chapter 7, Work Breakdown Structure, describes the structure used for developing the cost estimates, which will also be used to manage the project. The chapter defines the scope of work of each element down to level 3.

  15. A conceptual framework for rationalized and standardized Universal Newborn Hearing Screening (UNHS) programs.

    Congenital hearing loss is the most frequent birth defect. The American Academy of Pediatrics and the Joint Committee on Infant Hearing established quality of care process indicators for Universal Newborn Hearing Screening starting from 1999. In a previous systematic review of Universal Newborn Hearing Screening studies we highlighted substantial variability in program design and in reported performance data. In order to overcome these heterogeneous findings we think it is necessary to optimize the implementation of Universal Newborn Hearing Screening programs with an appropriate application of the planning, executing, and monitoring, verifications and reporting phases. For this reason we propose a conceptual framework that logically integrates these three phases and, consequently, a tool (a check-list) for their rationalization and standardization.Our paper intends to stimulate debate on how to ameliorate the routine application of high quality Universal Newborn Hearing Screening programs. The conceptual framework is proposed to optimize, rationalise and standardise their implementation. The checklist is intended to allow an inter-program comparison by removing heterogeneity in processes description and assessment. PMID:26872853

  16. Conceptual framework for standard economic evaluation of physical activity programs in primary prevention.

    Wolfenstetter, Silke B

    2011-12-01

    Economic evaluations of primary prevention physical activity programs have gained importance because of scarce resources in health-care-systems. A concept for economic evaluation should be based on the efficacy of physical activity, the standard methods of economic evaluation and the aims of public health. Previous publications have examined only parts of these components and have not developed a comprehensive conceptual framework; it is the objective of this article to develop such a framework. The derived method should aid decision makers and staff members of intervention programs in reviewing and conducting an economic evaluation. A literature search of articles was done using six electronic databases. Referenced works for standard methods and more comprehensive approaches for evaluation of preventive programs were studied. The newly developed conceptual framework for economic evaluation includes: (1) the type of physical activity program; (2) features of a selected study population; (3) the outcome dimension comprising exercise efficacy, reach, recruitment, response rate, maintenance, compliance and adverse health effects plus the social impact; and (4) the cost dimension consisting of program development costs, program implementation costs including the implementation, recruitment, program, participants' time costs and savings resulting from the health effects of the intervention. Cost-effectiveness also depends on the methodology, such as the chosen perspective, data collection, valuation methods and discounting. If an intervention is not considered cost-effective, it is necessary to check each dimension to find possible failures in order to learn for future interventions. A more detailed economic evaluation is of utmost importance for improved comparability and transferability. PMID:21773728

    2013-07-01

    The Radiation Protection Center of the Iraqi Ministry of Environment is developing a groundwater monitoring program (GMP) for the Al-Tuwaitha Nuclear Research Center located near Baghdad, Iraq. The Al-Tuwaitha Nuclear Research Center was established in about 1960 and is currently being cleaned-up and decommissioned by Iraqs Ministry of Science and Technology. This Groundwater Monitoring Program Plan (GMPP) and Conceptual Site Model (CSM) support the Radiation Protection Center by providing: A CSM describing the hydrogeologic regime and contaminant issues, recommendations for future groundwater characterization activities, and descriptions of the organizational elements of a groundwater monitoring program. The Conceptual Site Model identifies a number of potential sources of groundwater contamination at Al-Tuwaitha. The model also identifies two water-bearing zones (a shallow groundwater zone and a regional aquifer). The depth to the shallow groundwater zone varies from approximately 7 to 10 meters (m) across the facility. The shallow groundwater zone is composed of a layer of silty sand and fine sand that does not extend laterally across the entire facility. An approximately 4-m thick layer of clay underlies the shallow groundwater zone. The depth to the regional aquifer varies from approximately 14 to 17 m across the facility. The regional aquifer is composed of interfingering layers of silty sand, fine-grained sand, and medium-grained sand. Based on the limited analyses described in this report, there is no severe contamination of the groundwater at Al-Tuwaitha with radioactive constituents. However, significant data gaps exist and this plan recommends the installation of additional groundwater monitoring wells and conducting additional types of radiological and chemical analyses.

  20. Conceptual design

    International Nuclear Information System (INIS)

    This report documents the TFE Conceptual Design, which provided the design guidance for the TFE Verification program. The primary goals of this design effort were: (1) establish the conceptual design of an in-core thermionic reactor for a 2 Mw(e) space nuclear power system with a 7-year operating lifetime; (2) demonstrate scalability of the above concept over the output power range of 500 kW(e) to 5 MW(e); and (3) define the TFE which is the basis for the 2 MW (e) reactor design. This TFE specification provided the basis for the test program. These primary goals were achieved. The technical approach taking in the conceptual design effort is discussed in Section 2, and the results are discussed in Section 3. The remainder of this introduction draws a perspective on the role that this conceptual design task played in the TFE Verification Program

    1993-07-01

    The Salado Two-Phase Flow Laboratory Program was established to address concerns regarding two-phase flow properties and to provide WIPP-specific, geologically consistent experimental data to develop more appropriate correlations for Salado rock to replace those currently used in Performance Assessment models. Researchers in Sandia`s Fluid Flow and Transport Department originally identified and emphasized the need for laboratory measurements of Salado threshold pressure and relative permeability. The program expanded to include the measurement of capillary pressure, rock compressibility, porosity, and intrinsic permeability and the assessment of core damage. Sensitivity analyses identified the anhydrite interbed layers as the most likely path for the dissipation of waste-generated gas from waste-storage rooms because of their relatively high permeability. Due to this the program will initially focus on the anhydrite interbed material. The program may expand to include similar rock and flow measurements on other WIPP materials including impure halite, pure halite, and backfill and seal materials. This conceptual plan presents the scope, objectives, and historical documentation of the development of the Salado Two-Phase Flow Program through January 1993. Potential laboratory techniques for assessing core damage and measuring porosity, rock compressibility, capillary and threshold pressure, permeability as a function of stress, and relative permeability are discussed. Details of actual test designs, test procedures, and data analysis are not included in this report, but will be included in the Salado Two-Phase Flow Laboratory Program Test Plan pending the results of experimental and other scoping activities in FY93.

    1992-06-15

    The Solenoidal Tracker At RHIC (STAR) will search for signatures of quark-gluon plasma (QGP) formation and investigate the behavior of strongly interacting matter at high energy density. The emphasis win be the correlation of many observables on an event-by-event basis. In the absence of definitive signatures for the QGP, it is imperative that such correlations be used to identify special events and possible signatures. This requires a flexible detection system that can simultaneously measure many experimental observables. The physics goals dictate the design of star and it`s experiment. To meet the design criteria, tracking, momentum analysis, and particle identification of most of the charged particles at midrapidity are necessary. The tracking must operate in conditions at higher than the expected maximum charged particle multiplicities for central Au + Au collisions. Particle identification of pions/kaons for p < 0.7 GeV/c and kaons/protons for p < 1 GeV/c, as well as measurement of decay particles and reconstruction of secondary vertices will be possible. A two-track resolution of 2 cm at 2 m radial distance from, the interaction is expected. Momentum resolution of {Delta}p/p {approximately} 0.02 at p = 0.1 GeV/c is required to accomplish the physics, and,{Delta}p/p of several percent at p = 10 GeV/c is sufficient to accurately measure the rapidly failing spectra at high Pt and particles from mini-jets and jets.

  5. Conceptual Model for Assessing the Minimum Size Area for an Area-Wide Integrated Pest Management Program

    International Nuclear Information System (INIS)

    A conceptual model was developed based on the two basic spatial elements of area-wide integrated pest management (AW-IPM), a core area and a buffer zone, to determine the minimum size of the protected area for the program to be technically feasible and economically justifiable. The model consisted of a biological part (insect dispersal) and an economic part. The biological part used random walks and diffusion equations to describe insect dispersal and to determine the minimum width of the buffer zone required to protect the core area from immigration of pests from outside. In the economic part, the size of the core area was calculated to determine the point at which the revenues from the core area equal the control costs. This model will need to be calibrated and validated for each species and geographic location. Tsetse flies and the Mediterranean fruit fly are used as case studies to illustrate the model. (author)

    The fate and transport of 129I in the environment and potential remediation technologies are currently being studied as part of environmental remediation activities at the Hanford Site. A conceptual model describing the nature and extent of subsurface contamination, factors that control plume behavior, and factors relevant to potential remediation processes is needed to support environmental remedy decisions. Because 129I is an uncommon contaminant, relevant remediation experience and scientific literature are limited. Thus, the conceptual model also needs to both describe known contaminant and biogeochemical process information and to identify aspects about which additional information needed to effectively support remedy decisions. this document summarizes the conceptual model of iodine behavior relevant to iodine in the subsurface environment at the Hanford site.

    Test beam and irradiation facilities are the key enabling infrastructures for research in high energy physics (HEP) and astro-particles. In the last 11 years the Beam-Test Facility (BTF) of the DA{\\Phi}NE accelerator complex in the Frascati laboratory has gained an important role in the European infrastructures devoted to the development and testing of particle detectors. At the same time the BTF operation has been largely shadowed, in terms of resources, by the running of the DA{\\Phi}NE electron-positron collider. The present proposal is aimed at improving the present performance of the facility from two different points of view: extending the range of application for the LINAC beam extracted to the BTF lines, in particular in the (in some sense opposite) directions of hosting fundamental physics and providing electron irradiation also for industrial users; extending the life of the LINAC beyond or independently from its use as injector of the DA{\\Phi}NE collider, as it is also a key element of the electron/...

    The sport of volleyball creates considerable dynamic trunk stability demands. Back injury occurs all too frequently in volleyball, particularly among female athletes. The purpose of this clinical commentary is to review functional anatomy, muscle coactivation strategies, assessment of trunk muscle performance, and the characteristics of effective exercises for the trunk or core. From this information, a conceptual progressive 3-phase volleyball-specific training program is presented to improve dynamic trunk stability and to potentially reduce the incidence of back injury among volleyball athletes. Phase 1 addresses low-velocity motor control, kinesthetic awareness, and endurance, with the clinician providing cues to teach achievement of biomechanically neutral spine alignment. Phase 2 focuses on progressively higher velocity dynamic multiplanar endurance, coordination, and strength-power challenges integrating upper and lower extremity movements, while maintaining neutral spine alignment. Phase 3 integrates volleyball-specific skill simulations by breaking down composite movement patterns into their component parts, with differing dynamic trunk stability requirements, while maintaining neutral spine alignment. Prospective research is needed to validate the efficacy of this program. PMID:18978452

    Cavagna, Luca; Ricci, Sergio; Travaglini, Lorenzo

    2011-11-01

    This paper presents a design framework called NeoCASS (Next generation Conceptual Aero-Structural Sizing Suite), developed at the Department of Aerospace Engineering of Politecnico di Milano in the frame of SimSAC (Simulating Aircraft Stability And Control Characteristics for Use in Conceptual Design) project, funded by EU in the context of 6th Framework Program. It enables the creation of efficient low-order, medium fidelity models particularly suitable for structural sizing, aeroelastic analysis and optimization at the conceptual design level. The whole methodology is based on the integration of geometry construction, aerodynamic and structural analysis codes that combine depictive, computational, analytical, and semi-empirical methods, validated in an aircraft design environment. The work here presented aims at including the airframe and its effect from the very beginning of the conceptual design. This aspect is usually not considered in this early phase. In most cases, very simplified formulas and datasheets are adopted, which implies a low level of detail and a poor accuracy. Through NeoCASS, a preliminar distribution of stiffness and inertias can be determined, given the initial layout. The adoption of empirical formulas is reduced to the minimum in favor of simple numerical methods. This allows to consider the aeroelastic behavior and performances, as well, improving the accuracy of the design tools during the iterative steps and lowering the development costs and reducing the time to market. The result achieved is a design tool based on computational methods for the aero-structural analysis and Multi-Disciplinary Optimization (MDO) of aircraft layouts at the conceptual design stage. A complete case study regarding the TransoniCRuiser aircraft, including validation of the results obtained using industrial standard tools like MSC/NASTRAN and a CFD (Computational Fluid Dynamics) code, is reported. As it will be shown, it is possible to improve the degree of

    Most earlier group interventions for caregivers of demented persons lacked a theoretical basis to guide the intervention process and focused on providing information and practical advice and encouraging the expression of feelings. This article presents the process of a group intervention with emphasis on its conceptual framework, components and characteristics. As caregivers are exposed to numerous daily stressful demands, the intervention's conceptual framework was derived from Lazarus and Folkman's transactional theory of stress and coping and Folkman's Coping Effectiveness Training Program. The central aim of the intervention was to improve the ability of caregivers to cope with the stressful demands at the core of caring for a demented person, rather than to focus on information and the task-oriented aspects of caring. The two components of the intervention deal with the cognitive appraisal of stressors and coping strategies, with a view to determining which strategies are most appropriate on the basis of the changeability of stressors. Three coping strategies were proposed: problem solving (problem-focused coping to deal with changeable stressors), reframing (emotion-focused coping to manage the emotional response to unchangeable stressors), and seeking social support (problem- or emotion-focused coping). The most salient characteristics of this group intervention were its intensity (15 meetings) and its focus on the caregivers' daily reality, which provided concrete reference points for the discussion of conceptual notions.

    The authors are studying conceptual designs of selected nondestructive assay (NDA) instruments for the near-real-time accounting system at the rokkasho Reprocessing Plant (RRP) of Japan Nuclear Fuel Limited (JNFL). The JNFL RRP is a large-scale commercial reprocessing facility for spent fuel from boiling-water and pressurized-water reactors. The facility comprises two major components: the main process area to separate and produce purified plutonium nitrate and uranyl nitrate from irradiated reactor spent fuels, and the co-denitration process area to combine and convert the plutonium nitrate and uranyl nitrate into mixed oxide (MOX). The selected NDA instruments for conceptual design studies are the MOX-product canister counter, holdup measurement systems for calcination and reduction furnaces and for blenders in the co-denitration process, the isotope dilution gamma-ray spectrometer for the spent fuel dissolver solution, and unattended verification systems. For more effective and practical safeguards and material control and accounting at RRP, the authors are also studying the conceptual design for the UO{sub 3} large-barrel counter. This paper discusses the state-of-the-art NDA conceptual design and research and development activities for the above instruments.

  14. Development of a conceptual framework to guide a program of research exploring nurse-to-nurse communication.

    Carrington, Jane M

    2012-06-01

    Research in nursing informatics has been described as problem based rather than theory guided. Furthermore, few examples exist in the literature where the process of theory development is described. This article describes a process used to develop a conceptual framework that supports a theory-driven program of research in nursing informatics. The conceptual framework combines Symbolic Interaction Theory and Information Theory. Constructs of Symbolic Interaction Theory (mind, self, and society) and Information Theory (entropy, negentropy, redundancy, probability, and noise) were then organized according to Gerbner's Communication Model. Theory derivation was the method used for organizing abstract constructs and reducing them to a measurable level. Theory derivation was supplemented with initial research findings. The measurable or middle-range constructs were then organized in a meaningful manner for conceptual framework development. The use of theory derivation to develop a conceptual framework to support theory-driven nursing informatics research will be discussed. The framework entitled "Effective Nurse-to-Nurse Communication" that guides a program of research will then be presented. PMID:22411412

  15. Conceptual development of “at-homeness” despite illness and disease: A review

    Directory of Open Access Journals (Sweden)

    Joakim Öhlén

    2014-05-01

    Full Text Available Only one empirical study, the one by Zingmark, Norberg and Sandman published in 1995, explicitly focuses on at-homeness, the feeling of being metaphorically at-home, as a particular aspect of wellness. However, other studies reveal aspects of at-homeness, but if or how such aspects of at-homeness are related to each other is unclear. For this reason, the aim was to review Scandinavian nursing research related to at-homeness in the context of wellness–illness in severe and long-term conditions in order to take a step towards conceptual clarification of “at-homeness.” The review included interpretive studies related to severe and long-term illness conducted in Sweden: 10 original articles and 5 doctoral theses. “At-homeness” was found to be a contextually related meaning of wellness despite illness and disease embedded in the continuum of being metaphorically at-home and metaphorically homeless. This was characterized by three interrelated aspects and four processes: being safe through expanding–limiting experiences of illness and time, being connected through reunifying–detaching ways of relating, and being centred through recognition–non-recognition of oneself in the experience and others giving–withdrawing a place for oneself. This conceptualization is to be regarded as a step in conceptual clarification. Further empirical investigation and theoretical development of “at-homeness” are needed. The conceptualization will be a step of plausible significance for the evaluation of interventions aimed at enhancing wellness for people with severe long-term illness, such as the frail elderly, and people with chronic illness or palliative care needs.

    The U. S. Department of Energy?s Richland Operations Office has initiated efforts to adapt and implement the Features, Events, and Processes (FEPs) methodology (used in scenario development for nuclear waste disposal programs) to the environmental management and remediation problems facing the Hanford Site. These efforts have shown that modification of the FEPs methodology to incorporate the use of Process Relationship Diagrams (PRD) is effective in facilitating the development of conceptual models and selection of potentially relevant factors to be incorporated into a specific performance assessment. In developing this methodology for Hanford, a master PRD was created to provide an organization structure for identifying the potentially relevant factors (i.e. FEPs) and for illustrating the relationships between these factors. This organizational framework was developed to match the organization of current Hanford site-wide performance assessment activities and to facilitate screening of the FEPs relevant to the problems (and conceptual models) that need to be addressed at the site. However, the link between Hanford specific FEPs and the international list of FEPs was maintained to demonstrate completeness and perhaps to expand the usefulness of the international list for other environmental programs.

  17. A Comprehensive and Systematic Approach to Developing and Documenting Conceptual Models of Contaminant Release and Migration at the Hanford Site

    International Nuclear Information System (INIS)

    The U. S. Department of Energy?s Richland Operations Office has initiated efforts to adapt and implement the Features, Events, and Processes (FEPs) methodology (used in scenario development for nuclear waste disposal programs) to the environmental management and remediation problems facing the Hanford Site. These efforts have shown that modification of the FEPs methodology to incorporate the use of Process Relationship Diagrams (PRD) is effective in facilitating the development of conceptual models and selection of potentially relevant factors to be incorporated into a specific performance assessment.

  18. BRAHMS: Conceptual design report. Forward angle and midrapidity hadron spectrometers at RHIC

    International Nuclear Information System (INIS)

    The Broad RAnge Hadron Magnetic Spectrometers experiment (BRAHMS) is designed to measure charged hadrons over a wide range of rapidity and transverse momentum for all available beams and energies. This conceptual design report describes the BRAHMS detector and how it will be installed and operated at RHIC. Chapter 2 presents an overview of the physics program to be achieved with the BRAHMS Experiment. This is followed in Chapter 3 by an overview of the detector systems, a description which is close to earlier designs but changed to reflect updates. The magnet design is reviewed in Chapter 4. Chapter 5 describes the requirements that the BRAHMS Experiment sets for the intersection region. The arguments for the proposed positioning of the two magnet arms are presented. The needed support buildings and their possible placements are discussed. Chapter 6 examines the requirements on the elements of the forward arm, and demonstrates the feasibility of the proposed combination of magnets and tracking detectors. Most of the detectors are small TPC's, and several features of a prototoye TPC and the testing thereof are describes. The particle identification in BRAHMS is achieved by time-of-flight techniques and Cerenkov counters. This is describes in Chapter 7. The global detectors, i.e., the beam-beam counters and the multiplicity detector, are described next in Chapter 8. The concept for a centrality detector based on silicon strips is presented; a backup scheme employs an array of proportional gas counters. Considerations on data aquisition and triggers, as given next in Chapter 9, are fairly conventional and shoud not pose any major problems for development. The cost estimate for the experiment is given last; the total budget for BRAHMS is within the original goal

  19. Modular programming method at JAERI

    International Nuclear Information System (INIS)

    In this report the histories, concepts and a method for the construction and maintenance of nuclear code systems of Japan Atomic Energy Research Institute (JAERI) are presented. The method is mainly consisted of novel computer features. The development process of the features and experiences with them which required many man-months and efforts of scientists and engineers of JAERI and a computer manufacturer are also described. One of the features is a file handling program named datapool. The program is being used in code systems which are under development at JAERI. The others are computer features such as dynamic linking, reentrant coding of Fortran programs, interactive programming facility, document editor, quick system output viewer and editor, flexible man-machine interactive Fortran executor, and selective use of time-sharing or batch oriented computer in an interactive porgramming environment. In 1980 JAERI has replaced its two old computer systems by three FACOM M-200 computer systems and they have such features as mentioned above. Since 1981 most code systems, or even big single codes can be changed to modular code systems even if the developers or users of the systems will not recognize the fact that they are using modular code systems. The purpose of this report is to describe our methodology of modular programming from aspects of computer features and some of their applications to nuclear codes to get sympathetic understanding of it from persons of organizations who are concerned with the effective use of computers, especially, in nuclear research fields.

  20. Public health and health promotion capacity at national and regional level: a review of conceptual frameworks

    2014-04-01

    Full Text Available The concept of capacity building for public health has gained much attention during the last decade. National as well as international organizations increasingly focus their efforts on capacity building to improve performance in the health sector. During the past two decades, a variety of conceptual frameworks have been developed which describe relevant dimensions for public health capacity. Notably, these frameworks differ in design and conceptualization. This paper therefore reviews the existing conceptual frameworks and integrates them into one framework, which contains the most relevant dimensions for public health capacity at the country or regional level. A comprehensive literature search was performed to identify frameworks addressing public health capacity building at the national or regional level. We content-analysed these frameworks to identify the core dimensions of public health capacity. The dimensions were subsequently synthesized into a set of thematic areas to construct a conceptual framework which describes the most relevant dimensions for capacities at the national or regional level. The systematic review resulted in the identification of seven core domains for public health capacity: resources, organizational structures, workforce, partnerships, leadership and governance, knowledge development and country specific context. Accordingly, these dimensions were used to construct a framework, which describes these core domains more in detail. Our research shows that although there is no generally agreed upon model of public health capacity, a number of key domains for public health and health promotion capacity are consistently recurring in existing frameworks, regardless of their geographical location or thematic area. As only little work on the core concepts of public health capacities has yet taken place, this study adds value to the discourse by identifying these consistencies across existing frameworks and by synthesising

  6. Study of a conceptual nuclear energy center at Green River, Utah. Final summary report

    International Nuclear Information System (INIS)

    This document summarizes a conceptual study on the feasibility and practicality of developing a nuclear energy center (NEC) at a representative Western site. The site selected for this conceptual study, an area of about 50 square miles, is located 15 miles south of Green River, Utah. The conceptual NEC would consist of nine nuclear electric generating units, arranged on the site in three clusters of three reactors each (triads), separated by about 2 1/2 miles. Of the total electric output of 11,250 MWe that the NEC could produce, about 82% is assumed to be transmitted out of Utah to Colorado, New Mexico, Arizona, Nevada, and California. The technical engineering issues studied included geology and seismology, plant design, low-level radioactive waste disposal, transmission, and construction schedules and costs. Socioeconomic issues included were demographics, land use, community service needs, and fiscal impacts. Environmental considerations included terrestrial and aquatic ecology, visual impact, and secondary population impacts. Radiological issues were concerned with the safety and risks of an NEC and an on-site low-level waste facility. Institutional issues included methods of ownership, taxation, implications of energy export, and water allocation. The basic finding was that an NEC would be technically feasible, but a number of socioeconomic and institutional issues would require resolution before a Western regional NEC could be considered a viable power plant siting option

    The 160 GeV polarised muon beam available at CERN, with positive or negative charge, makes COMPASS a unique place for GPD studies. The first GPD related COMPASS results come from exclusive vector meson production on transversely polarised protons and deuterons. The data were taken in 2003-2010 with large solid-state polarised targets, although without detection of recoil particles. Results on various transverse target spin dependent azimuthal asymmetries are presented and their relations to GPDs are discussed. The dedicated COMPASS GPD program started in 2012 with commissioning of a new long liquid hydrogen target and new detectors such as the large recoil proton detector and the large-angle electromagnetic calorimeter. It was followed by a short pilot 'DVCS run'. The performance of the setup and first results on DVCS and exclusive $\\pi ^0$ channels have been demonstrated. The full data taking for the GPD program approved within COMPASS-II proposal is planned for 2016 and 2017.

    The effective cost management during the conceptual design phase of a product is essential to develop a product with minimum cost and desired quality. The integration of the methodologies of quality function deployment (QFD), value engineering (VE) and target costing (TC) could be applied to the continuous improvement of any product during product development. To optimize customer satisfaction and total cost of a product, a mathematical model is established in this paper. This model integrates QFD, VE and TC under multi-objective optimization frame work. A case study on domestic refrigerator is presented to show the performance of the proposed model. Goal programming is adopted to attain the goals of maximum customer satisfaction and minimum cost of the product.

    1996-07-26

    This Final Technical Report presents the accomplishments on Phase 2 of the Advanced Turbine Systems (ATS). The ATS is an advanced, natural gas fired gas turbine system that will represent a major advance on currently available industrial gas turbines in the size range of 1--20 MW. This report covers a market-driven development. The Market Survey reported in Section 5 identified the customer`s performance needs. This market survey used analyses performed by Solar turbine Incorporated backed up by the analyses done by two consultants, Research Decision Consultants (RDC) and Onsite Energy Corporation (Onsite). This back-up was important because it is the belief of all parties that growth of the ATS will depend both on continued participation in Solar`s traditional oil and gas market but to a major extent on a new market. This new market is distributed electrical power generation. Difficult decisions have had to be made to meet the different demands of the two markets. Available resources, reasonable development schedules, avoidance of schedule or technology failures, probable acceptance by the marketplace, plus product cost, performance and environmental friendliness are a few of the complex factors influencing the selection of the Gas Fired Advanced Turbine System described in Section 3. Section 4 entitled ``Conversion to Coal`` was a task which addresses the possibility of a future interruption to an economic supply of natural gas. System definition and analysis is covered in Section 6. Two major objectives were met by this work. The first was identification of those critical technologies that can support overall attainment of the program goals. Separate technology or component programs were begun to identify and parameterize these technologies and are described in Section 7. The second objective was to prepare parametric analyses to assess performance sensitivity to operating variables and to select design approaches to meet the overall program goals.

    Full Text Available The NUSTAR Collaboration brings together several hundred scientists to form one of the four scientific pillars of the future FAIR facility. NUSTAR aims at the exploitation of intense radioactive beams with energies up to 1.5 GeV/u in order to explore nuclei with large neutron or proton excess. The project has evolved over the last years and now reached a state where a large fraction of the core program is financed, partly built, and even ready for operation. With the signing of the FAIR convention in 2010 and the start of construction, the sub-projects in NUSTAR gain momentum and look forward to commissioning and first beams in this decade. The present status of the project will be presented, focusing on the instrumentation to be applied in the various experimental areas behind the Super-FRS fragment separator, which is the central instrument of NUSTAR.

  14. Methodology of life cycle cost with risk expenditure for offshore process at conceptual design stage

    International Nuclear Information System (INIS)

    This study proposed a new LCC (life cycle cost) methodology with the risk expenditure taken into account for comparative evaluation of offshore process options at their conceptual design stage. The risk expenditure consisted of the failure risk expenditure and the accident risk expenditure. The former accounted for the production loss and the maintenance expense due to equipment failures while the latter reflected the asset damage and the fatality worth caused by disastrous accidents such as fire and explosion. It was demonstrated that the new LCC methodology was capable of playing the role of a process selection basis in choosing the best of the liquefaction process options including the power generation systems for a floating LNG (Liquefied natural gas) production facility. Without the risk expenditure, a simple economic comparison apparently favored the mixed refrigerant cycle which had the better efficiency. The new methodology with the risk expenditure, however, indicated that the nitrogen expansion cycle driven by steam turbines should be the optimum choice, mainly due to its better availability and safety. -- Highlights: → The study presented the methodology of the LCC with the risk expenditure for the conceptual design of offshore processes. → The proposed methodology demonstrated the applicability of the liquefaction unit with the power generation system of LNG FPSO. → Without the risk expenditure, a simple economic comparison apparently favored the mixed refrigerant cycle which had the better efficiency. → The new methodology indicated that the nitrogen expansion cycle driven by steam turbines is the optimum choice due to its better availability and safety.

    Prenatal development is recognized as a critical period in the etiology of obesity and cardiometabolic disease. Potential strategies to reduce maternal obesity-induced risk later in life have been largely overlooked. In this paper, we first propose a conceptual framework for the role of public health and preventive medicine in mitigating the effects of fetal programming. Second, we review a small but growing body of research (through August 2015) that examines interactive effects of maternal obesity and two public health foci - diet and physical activity - in the offspring. Results of the review support the hypothesis that diet and physical activity after early life can attenuate disease susceptibility induced by maternal obesity, but human evidence is scant. Based on the review, we identify major gaps relevant for prevention research, such as characterizing the type and dose response of dietary and physical activity exposures that modify the adverse effects of maternal obesity in the offspring. Third, we discuss potential implications of interactions between maternal obesity and postnatal dietary and physical activity exposures for interventions to mitigate maternal obesity-induced risk among children. Our conceptual framework, evidence review, and future research directions offer a platform to develop, test, and implement fetal programming mitigation strategies for the current and future generations of children.

    A key component in risk assessment of contaminated sites is in the formulation of a conceptual site model (CSM). A CSM is a simplified representation of reality and forms the basis for the mathematical modeling of contaminant fate and transport at the site. The CSM should therefore identify...... opinion at different knowledge levels. The developed BBNs combine data from desktop studies and initial site investigations with expert opinion to assess which of the CSMs are more likely to reflect the actual site conditions. The method is demonstrated on a Danish field site, contaminated...... with chlorinated ethenes. Four different CSMs are developed by combining two contaminant source zone interpretations (presence or absence of a separate phase contamination) and two geological interpretations (fractured or unfractured clay till). The beliefs in each of the CSMs are assessed sequentially based...

    Education on the subject of groundwater is crucial for sustainability. Nevertheless, international studies with students across different age groups have shown that the basic hydrogeological concept of groundwater defined as water within porous and permeable rocks is not an established everyday notion. Drawing from international research, a multimedia learning program Zwischen Regenwolke und Wasserhahn (between the rain cloud and the tap) was developed, which incorporates specific insights from the fields of conceptual change research, multimedia research, and the model of educational reconstruction. The effectiveness of the learning program was ascertained by means of two studies with Austrian seventh grade pupils as well as teacher-training students from the fields of biology and geography in order to ascertain the effectiveness of the learning program. Using a quasi-experimental research design, the participants' conceptions and knowledge of groundwater were determined in a pre- and post-test. The pupils and students greatly benefitted from working through the learning software independently. Their knowledge of groundwater increased significantly compared to the control group and there was a highly significant increase in the number of scientifically correct notions of groundwater. The acceptance of the program was also generally very high. The results indicate that theory-guided multimedia learning programs can play an important role in the transfer of research results to classroom settings, especially in science education.

    This paper provides an overview of the construction of a conceptual framework regarding ICT-Assistive Technology (ICT-AT) competence development, designed to gain awareness of the elements involved and to facilitate the understanding and exchange among stakeholders of the ENTELIS (European Network for Technology Enhanced Learning in an Inclusive Society) project. The framework was designed based on the basic principles of Activity Theory, which however have been adapted and adjusted to the project's objectives. Hence, it includes a map of actors and other parameters functioning in a person surrounding "ecosystem", and it allows us to understand and map roles, expectations, barriers, as well as to devise solutions to tackle digital divide. Taking as a starting and central point the person and his/her wish to self-determination and fulfilment (quality of life) and the related needs, it provides a map of how the various concepts and variables interact within the theoretical and methodological perspective of the collection, description and assessment of experiences in ICT-AT education and competences development of persons with disabilities (PwD) of all ages. The conceptual framework represents two interacting learning activity systems: (a) the internal system of the end-user, which includes the end-user and his/her needs, the setting where learning takes place and the other actors involved, and (b) the external system, which embraces the internal system but also wider issues of policy and practice and experiences and 'actors' that contribute to the development and use of ICT and ICT-AT skills in all areas of life. The elements of these systems and their interaction provide the basis for analysing experiences and advancing knowledge relevant for bridging the digital divide. PMID:26294545

    This is a final technical report for a project of the U.S Nuclear Regulatory Commission (sponsored contract NRC-04-090-51) with the University of Arizona. The contract was an optional extension that was initiated on July 21, 1994 and that expired on May 31, 1995. The project manager was Thomas J. Nicholson, Office of Nuclear Regulatory Research. The objectives of this contract were to examine hypotheses and conceptual models concerning unsaturated flow and transport through fractured rock, and to design and execute confirmatory field and laboratory experiments to test these hypotheses and conceptual models at the Apache Leap Research Site near Superior, Arizona. The results discussed here are products of specific tasks that address a broad spectrum of issues related to flow and transport through fractures. Each chapter in this final report summarizes research related to a specific set of objectives and can be read and interpreted as a separate entity. The tasks include detection and characterization of historical rapid fluid flow through fractured rock and the relationship to perched water systems using environmental isotopic tracers of {sup 3}H and {sup 14}C, fluid- and rock-derived {sup 2343}U/{sup 238}U measurements, and geophysical data. The water balance in a small watershed at the ALRS demonstrates the methods of acounting for ET, and estimating the quantity of water available for infiltration through fracture networks. Grain density measurements were made for core-sized samples using a newly designed gas pycnometer. The distribution and magnitude of air permeability measurements have been measured in a three-dimensional setting; the subsequent geostatistical analysis is presented. Electronic versions of the data presented here are available from authors; more detailed discussions and analyses are available in technical publications referenced herein, or soon to appear in the professional literature.

The tasks include detection and characterization of historical rapid fluid flow through fractured rock and the relationship to perched water systems using environmental isotopic tracers of 3H and 14C, fluid- and rock-derived 2343U/238U measurements, and geophysical data. The water balance in a small watershed at the ALRS demonstrates the methods of acounting for ET, and estimating the quantity of water available for infiltration through fracture networks. Grain density measurements were made for core-sized samples using a newly designed gas pycnometer. The distribution and magnitude of air permeability measurements have been measured in a three-dimensional setting; the subsequent geostatistical analysis is presented. Electronic versions of the data presented here are available from authors; more detailed discussions and analyses are available in technical publications referenced herein, or soon to appear in the professional literature

    School anti-violence programs are united in their radical condemnation of aggression, generally equated with violence. The programs advocate its elimination by priming children's emotional and cognitive controls. What goes unrecognized is the embeddedness of aggression in human beings, as well as its positive psychological and moral functions. In…

    An innovative culturally-oriented supported-education program has been established in Israel to address the needs of religious Jewish persons with severe mental illness. This program is utilizing a highly regarded institution in the Orthodox communities, a Beit Midrash, a study hall for religious studies, as a context for rehabilitation. Based on open-ended interviews conducted with the staff members of this program, its conceptual framework and guiding principles have been identified and analyzed. In this program common principles of psychiatric rehabilitation have been adapted and incorporated into a context which has not been known so far as a context for psychiatric rehabilitation. In addition, innovative supported-education methods of work which are compatible with the cultural context of Orthodox Jewish persons have been implemented, such as opportunities provided to the participants to reconstruct their views of their daily struggles and enhance their sense of spirituality via the discussion of socially-oriented religious texts. The culturally-oriented context of the Beit Midrash enables outreach to a population which might otherwise not receive any services. This is a promising model for addressing the unique needs of religious persons with severe mental illness and for filling a gap in the resources available for the rehabilitation of this population in the community.

  8. Advanced turbine systems program conceptual design and product development. Task 3 -- System selection; Topical report

    Energy Technology Data Exchange (ETDEWEB)

    White, D.J.

    1994-07-01

    Solar Turbines Incorporated has elected to pursue an intercooled and recuperated (ICR) gas turbine system to exceed the goals of the DOE Advanced Turbine Systems (ATS) program, which are to develop and commercialize an industrial gas turbine system that operates at thermal efficiencies at least 15% higher than 1991 products, and with emissions not exceeding eight ppmv NOx and 20 ppmv CO and UHC. Solar`s goal is to develop a commercially viable industrial system (3--20 MW) driven by a gas turbine engine with a thermal efficiency of 50% (ATS50), with the flexibility to meet the differing operational requirements of various markets. Dispersed power generation is currently considered to be the primary future target market for the ICR in the 5--15 MW size class. The ICR integrated system approach provides an ideal candidate for the assumed dispersed power market, with its small footprint, easy transportability, and environmental friendliness. In comparison with other systems that use water or toxic chemicals such as ammonia for NOx control, the ICR has no consumables other than fuel and air. The low pressure ratio of the gas turbine engine also is favorable in that less parasitic power is needed to pump the natural gas into the combustor than for simple-cycle machines. Solar has narrowed the ICR configuration to two basic approaches, a 1-spool, and a 2-spool version of the ATS50. The 1-spool engine will have a lower first-cost but lower part-power efficiencies. The 2-spool ATS may not only have better part-power efficiency, its efficiency will also be less sensitive to reduced turbine rotor inlet temperature levels. Thus hot-end parts life can be increased with only small sacrifices in efficiency. The flexibility of the 2-spool arrangement in meeting customer needs is its major advantage over the 1-spool. This Task 3 Topical Report is intended to present Solar`s preliminary system selection based upon the initial trade-off studies performed to date.

    According to the International Labour Organization (ILO), decent work is critical to economic and social progress and well-being. The ILO's Decent Work Agenda outlines four directions (creating jobs, guaranteeing rights at work, extending social protection, promoting social dialogue) (ILO, 2015). While the Agenda's existence may imply consensus about its meaning, we contend that several conceptualizations of decent work exist in the global policy arena. Different institutional perspectives must be negotiated, and political, economic, social and health considerations balanced in its pursuit. This paper reports findings from a critical discourse analysis of 10 policy texts that aimed to reveal different health, economic, and social claims about decent work and how these are shaped by the work policy agendas of the ILO, World Health Organization, and World Bank. Themes emerging from the discourse analysis include the: challenges and realities of promoting "one" agenda; complex intersection between decent work, health and health equity concepts; emphasis on economic and pro-market interests versus the social dimensions of work; and, relative emphasis on individual versus collective responsibility for decent work. To our knowledge, this is a first attempt to contrast different conceptualizations of decent work involving these institutions. Our findings suggest that decent work is a contested notion, and that more than one "agenda" is operating in the face of vested institutional interests. Broader discourses are contributing to a reframing of decent work in economic, social and/or health terms and these are impacting which dimensions of work are taken up in policy texts over others. Results show how the language of economics acts as a disciplinary and regulatory power and its role as a normalizing discourse. We call for research that deepens understanding of how a social, economic and health phenomenon like work is discursively re-interpreted through different global

  11. Conceptual analysis of the fuel management strategy for the RA-3 research reactor at 10 MW

    International Nuclear Information System (INIS)

    The Argentine Research Reactor RA-3 was designed to produce radioisotopes and it operates with LEU (U3O8) fuel since 1990. Its initial power was 5 MW and it has recently been upgraded to 10 MW. The National Atomic Energy Commission (CNEA) is both its owner and operator. At the beginning of this year, the Nuclear Regulatory Authority extended its operation license to an authorised power of 10 MW after a series of modifications and tests carried out by the installation during 2002 and 2003. As a consequence of this power increase, the installation introduced some non-systematic modifications in its fuel management strategy with the purpose of preserving the operation period in 20 days approximately. The main change was to load 2 fuel elements per cycle in some cycles (instead of 1 as it used to be at 5 MW). The purpose of this work is to perform a conceptual analysis of possible fuel management strategies for the RA-3 reactor, that could provide quantitative elements for a safety assessment, as well as to evaluate the fuel management flexibility at 10 MW in compliance with standards in force. It is concluded that operation at 10 MW with a 2 FE/cycle strategy leads to a significant excess reactivity at the beginning of cycle, but still in compliance with the margins established by the standards of application.

    This study explored young children’s understandings of targeted lunar concepts, including when the moon can be observed, observable lunar phase shapes, predictable lunar patterns, and the cause of lunar phases. Twenty-one children (ages 7-9 years) from a multi-aged, self-contained classroom participated in this study. The instructional intervention included lunar data gathering, recording, and sharing, which integrated Starry Night planetarium software and an inquiry-based instruction on moon phases. Data were gathered using semi-structured interviews, student drawings, and a card sorting activity before and after instruction. Students’ lunar calendars and written responses, participant observer field notes, and videotaped class sessions also provided data throughout the study. Data were analyzed using constant comparative analysis. Nonparametric statistical analyses were also performed to support the qualitative findings. Results reflected a positive change in children’s conceptual understanding of all targeted concepts including the cause of moon phases, which is remarkable considering the complexity and abstractness of this spatial task. Results provided evidence that computer simulations may reduce the burden on children’s cognitive capacity and facilitate their learning of complex scientific concepts that would not be possible to learn on their own.

  13. Coming to see objects of knowledge: Guiding student conceptualization through teacher embodied instruction in a robotics programming class

    Science.gov (United States)

    Kwah, Helen

    This thesis explores the questions of how a teacher guides students to see concepts, and the role of gesture and gesture viewpoints in mediating the process of guidance. To examine these questions, two sociocultural theoretical frameworks--Radford's cultural-semiotic theory of knowledge objectification (e.g., 2003), and Goldman's Points of Viewing theory (e.g., 2007)--were applied to conduct a microanalytic, explanatory case study of the instructional activity of an exemplary teacher and his students in a middle school robotics programming class. According to Radford, students acquire concepts as they draw upon semiotic resources such as language and gesture to generalize and objectify initially concrete perceptions and actions. I applied Radford's framework to explain the mediations that a teacher might enact in guiding students to objectify and see concepts. Furthermore, I focused on gesture as semiotic means because of emergent research on gesture's role in communicating the visuospatial imagery that underlies math/ scientific concepts. I extended the view of gestures to the viewpoints constructed in gesture, and applied Goldman's theory to explain how perspectives might be actively constructed and shared in the process of guiding student conceptualization. Data was collected over a semester through participant observation, field notes, teacher and student interviews, and reviews of artifacts. Multimodal microanalyses were conducted on video data from eight class sessions. The findings provide confirmations and some disconfirmations about the applicability of Radford's and Goldman's theories for explaining a teacher's process of guiding student conceptualization. Notably, some of Radford's notions about de-contextualization and symbolic generalizations were not confirmed. Overall, the findings are summarized through three themes including, grounding, and perceptual organizers as two ways that gesture and other means served to both index and identify action

    In this paper, I investigate conceptual categories derived from developmental processing in a deep neural network. The similarity matrices of deep representation at each layer of neural network are computed and compared with their raw representation. While the clusters generated by raw representation stand at the basic level of abstraction, conceptual categories obtained from deep representation shows a bottom-up transition procedure. Results demonstrate a developmental course of learning from specific to general level of abstraction through learned layers of representations in a deep belief network.

    2001-01-01

    Pohang Accelerator Laboratory (PAL) is developing a Multipole Wiggler (MPW14) to utilize high-energy (approx 30 keV) synchrotron radiation at Pohang Light Source (PLS). The MPW14 is a hybrid type device to achieve maximum peak flux density and wide beam fan that can serve two beamlines. PLS MPW14-features period of 14 cm, minimum gap of 14 mm, 20 full field periods, maximum flux density of 2.06 T, 3036 mm total magnetic structure length. The peak flux density is very high compared to the other wigglers of similar pole gap and the period. The high peak flux density was possible using advanced new magnetic material and optimized magnetic geometry. The MPW14 will be used in hard X-ray region of 10-30 keV at 2.5 GeV electron energy. The total photon power is 6.19 kW and the peak power density is 5.27 kW/mrad sup 2 at 2.5 GeV, 150 mA. To withstand the big magnetic loads with minimum deflections, C-type support structure is designed with detailed FEM structural analysis. In this article, all the conceptual design e...

  18. A conceptual design of the RF system for the NSP high intensity proton accelerator at JAERI

    International Nuclear Information System (INIS)

    JAERI has been proposing the Neutron Science Project which aims at exploring the fields of basic science and nuclear technology using a high power spallation neutron source. The neutron source will be driven by a high intensity linear accelerator with an energy of 1.5 GeV and an average beam current of 5.33 mA and beam power of 8 MW. The RF system for the accelerator consists of a high-energy accelerator part and a low energy accelerator part. The maximum RF power requirements at the high and low energy accelerator parts are 25 MW and 8.3 MW, respectively. In this report, we describe the conceptual design of the RF system. In the low energy accelerator part, we estimated the requirement for the high-power amplifier tube and made the basis design for RF components. In the high energy accelerator part, we studied the effect of tuning errors, Lorentz forces and microphonics in the superconducting cavity. We calculated the klystron efficiency and supply power in the arrangement of where one klystron distributes the RF power to four cavities. We also considered an IOT RF system. Finally, we describe the electrical capacity and quantity of cooling water in the RF system. (author)

  19. Dielectric and Radiative Properties of Sea Foam at Microwave Frequencies: Conceptual Understanding of Foam Emissivity

    Peter W. Gaiser

    2012-04-01

    Full Text Available Foam fraction can be retrieved from space-based microwave radiometric data at frequencies from 1 to 37 GHz. The retrievals require modeling of ocean surface emissivity fully covered with sea foam. To model foam emissivity well, knowledge of foam properties, both mechanical and dielectric, is necessary because these control the radiative processes in foam. We present a physical description of foam dielectric properties obtained from the foam dielectric constant including foam skin depth; foam impedance; wavelength variations in foam thickness, roughness of foam layer interfaces with air and seawater; and foam scattering parameters such as size parameter, and refraction index. Using these, we analyze the scattering, absorption, reflection and transmission in foam and gain insights into why volume scattering in foam is weak; why the main absorption losses are confined to the wet portion of the foam; how the foam impedance matching provides the transmission of electromagnetic radiation in foam and maximizes the absorption; and what is the potential for surface scattering at the foam layers boundaries. We put all these elements together and offer a conceptual understanding for the high, black-body-like emissivity of foam floating on the sea surface. We also consider possible scattering regimes in foam.

  20. Building of a conceptual model at UE25-c hole complex

    International Nuclear Information System (INIS)

    US Geological Survey and Lawrence Berkeley Laboratory are attempting to construct a conceptual model of the UE25-c hole complex. An interdisciplinary approach is discussed where all the available data are integrated. Site geology, borehole geophysics and hydraulic test results at UE25-c hole complex suggest that groundwater flow may be controlled by fractures and faults. Significant clusters of fractures in the C-holes are perpendicular to bedding and may be cooling cracks or may be tectonically induced. Unresolved evidence indicates that a fault may intersect the C-holes. For these reasons a porous medium approximation of the rock in the saturated zone at the scale of a well test may be inappropriate. Instead, an Equivalent Discontinuum Model is proposed to model the UE25-c complex hydrology. EDM does not reproduce every geometrical detail of the real system, but instead, attempts to reproduce the observed behavior of the fracture system while preserving the inherent discontinuous nature of the system. 6 refs., 7 figs

    Drawing rocks at primary school: a tool for emerging misconceptions and promoting conceptual change Luca Benciolini Dipartimento di Fisica, Chimica e Ambiente, Università di Udine (Italy) and Giuseppe Muscio Museo Friulano di Storia Naturale (Udine, Italy) In order to investigate spontaneous ideas of children about rock samples, the Museo Friulano di Storia Naturale in collaboration with the Università di Udine submitted six classrooms of fifth and fourth grade-students to a specific test. One hundred thirty-three students without a specific background in Earth Sciences were asked to give a) a written description of a rock sample; b) a drawing of the sample; c) a written short story about the sample. The selected thirty-five samples in the opinion of the researchers contain 255 geologically relevant self-evident characters such as fossils, clastic textures, planar discontinuities and so on. Childs spontaneously described 209 geological characters. Forty-seven fifth-grade students (group A) have been previously followed specific training in multisensory description of objects and observed the 90% of the geologically relevant characters. Group B (forty-three fifth-grade) and group C (forty-three fourth-grade) on the contrary, without any previous instructions discovered the 77%. In order to follow childs building their knowledge through experience we found that the main problem was the lack of consistency between written and drawing description. Heterogeneities as evident as a magmatic contact have been correctly represented by the drawing but it has not been worth of any attention in the written description. On the contrary, written description may sometimes contain careful description of the clastic sedimentary process but these criteria are applied for example to a travertine, without any relations with observed characters. Descriptions and drawing of rock outcrops performed by university students demonstrate the persistence of this attitude. Thus, groups B and

    This report analyzes the economics of producing syncrude from oil shale combining underground and surface processing using Occidental's Modified-In-Situ (MIS) technology and Lawrence Livermore National Laboratory's (LLNL) Hot Recycled Solids (HRS) retort. These retorts form the basic technology employed for oil extraction from oil shale in this study. Results are presented for both Commercial and Pre-commercial programs. Also analyzed are Pre-commercialization cost of Demonstration and Pilot programs which will confirm the HRS and MIS concepts and their mechanical designs. These programs will provide experience with the circulating Fluidized Bed Combustor (CFBC), the MIS retort, the HRS retort and establish environmental control parameters. Four cases are considered: commercial size plant, demonstration size plant, demonstration size plant minimum CFBC, and a pilot size plant. Budget cost estimates and schedules are determined. Process flow schemes and basic heat and material balances are determined for the HRS system. Results consist of summaries of major equipment sizes, capital cost estimates, operating cost estimates and economic analyses. 35 figs., 35 tabs.

  3. Study of a conceptual nuclear energy center at Green River, Utah: licensing considerations

    International Nuclear Information System (INIS)

    This report examines the laws governing the location of a 9-unit nuclear energy center (NEC) near Green River, Utah. The time frame being considered for development of the conceptual NEC is from 1995 to 2013. Accordingly, the report is forced to speculate about some aspects of the plant, its site and its construction. Most of the report examines existing legal requirements for constructing an NEC. Where pertinent, changes in the law are discussed that would affect an NEC that is to be licensed in one or two decades. In general, no insurmountable legal problems exist that would prevent an NEC from being licensed at the Green River location. Several legal requirements pose significant concerns and would have to be faced before an NEC could be built. Among the major legal constraints are radiation protection, regulatory approval of financing, access to water, and local zoning restrictions. Two other constraints that involve legal matters are the wisdom of standardization of the units and the responsibility of the NEC builder to correct socio-economic impacts on the local area

    Physical bodies can be hot or cold, moving or standing,simple or complex. In all such cases one assumes that their respective temperature is a well defined attribute.  What if, however, the ordinary measurement of temperature by direct body contact is not possible?  One conjectures its value, and yes, its very existence, by reasoning based on basic principles of thermodynamics. Is There a Temperature?  Conceptual Challenges at High Energy, Acceleration and Complexity, by Dr. Tamás Sándor Bíró, begins by asking the questions “Do we understand and can we explain in a unified framework the temperature of distant radiation sources, including event horizons, and that of the quark matter produced in high energy accelerator experiments? Or the astounding fluctuations on financial markets?” The book reviews the concept of temperature from its beginnings through the evolution of classical thermodynamics and atomic statistical physics through contemporary models of high energy particle matter.  Based on the...

    A key component in risk assessment of contaminated sites is in the formulation of a conceptual site model (CSM). A CSM is a simplified representation of reality and forms the basis for the mathematical modeling of contaminant fate and transport at the site. The CSM should therefore identify the most important site-specific features and processes that may affect the contaminant transport behavior at the site. However, the development of a CSM will always be associated with uncertainties due to limited data and lack of understanding of the site conditions. CSM uncertainty is often found to be a major source of model error and it should therefore be accounted for when evaluating uncertainties in risk assessments. We present a Bayesian belief network (BBN) approach for constructing CSMs and assessing their uncertainty at contaminated sites. BBNs are graphical probabilistic models that are effective for integrating quantitative and qualitative information, and thus can strengthen decisions when empirical data are lacking. The proposed BBN approach facilitates a systematic construction of multiple CSMs, and then determines the belief in each CSM using a variety of data types and/or expert opinion at different knowledge levels. The developed BBNs combine data from desktop studies and initial site investigations with expert opinion to assess which of the CSMs are more likely to reflect the actual site conditions. The method is demonstrated on a Danish field site, contaminated with chlorinated ethenes. Four different CSMs are developed by combining two contaminant source zone interpretations (presence or absence of a separate phase contamination) and two geological interpretations (fractured or unfractured clay till). The beliefs in each of the CSMs are assessed sequentially based on data from three investigation stages (a screening investigation, a more detailed investigation, and an expert consultation) to demonstrate that the belief can be updated as more information

  10. A conceptual approach to the estimation of societal willingness-to-pay for nuclear safety programs

    International Nuclear Information System (INIS)

    The design, refurbishment and future decommissioning of nuclear reactors are crucially concerned with reducing the risk of radiation exposure that can result in adverse health effects and potential loss of life. To address this concern, large financial investments have been made to ensure safety of operating nuclear power plants worldwide. The efficacy of the expenditures incurred to provide safety must be judged against the safety benefit to be gained from such investments. We have developed an approach that provides a defendable basis for making that judgement. If the costs of risk reduction are disproportionate to the safety benefits derived, then the expenditures are not optimal; in essence the societal resources are being diverted away from other critical areas such as health care, education and social services that also enhance the quality of life. Thus, the allocation of society's resources devoted to nuclear safety must be continually appraised in light of competing needs, because there is a limit on the resources that any society can devote to extend life. The purpose of the paper is to present a simple and methodical approach to assessing the benefits of nuclear safety programs and regulations. The paper presents the Life-Quality Index (LQI) as a tool for the assessment of risk reduction initiatives that would support the public interest and enhance both safety and the quality of life. The LQI is formulated as a utility function consistent with the principles of rational decision analysis. The LQI is applied to quantify the societal willingness-to-pay (SWTP) for safety measures enacted to reduce of the risk of potential exposures to ionising radiation. The proposed approach provides essential support to help improve the cost-benefit analysis of engineering safety programs and safety regulations.

    In this work, we present the conceptual design of the backscattering time-of-flight spectrometer MIRACLES approved for construction at the long-pulse European Spallation Source (ESS). MIRACLES's unparalleled combination of variable resolution, high flux, extended energy, and momentum transfer (0.2-6 Å-1) ranges will open new avenues for neutron backscattering spectroscopy. Its remarkable flexibility can be attributed to 3 key elements: the long-pulse time structure and low repetition rate of the ESS neutron source, the chopper cascade that tailors the moderator pulse in the primary part of the spectrometer, and the bent Si(111) analyzer crystals arranged in a near-backscattering geometry in the secondary part of the spectrometer. Analytical calculations combined with instrument Monte-Carlo simulations show that the instrument will provide a variable elastic energy resolution, δ(ħ ω), between 2 and 32 μeV, when using a wavelength of λ ≈ 6.267 Å (Si(111)-reflection), with an energy transfer range, ħ ω, centered at the elastic line from -600 to +600 μeV. In addition, when selecting λ ≈ 2.08 Å (i.e., the Si(333)-reflection), δ(ħ ω) can be relaxed to 300 μeV and ħ ω from about 10 meV in energy gain to ca -40 meV in energy loss. Finally, the dynamic wavelength range of MIRACLES, approximately 1.8 Å, can be shifted within the interval of 2-20 Å to allow the measurement of low-energy inelastic excitations.

  13. Joint Assessment of Parameter and Conceptual Model Uncertainty at the Hanford Site 300 Area

    2005-12-01

    Assessment of conceptual model and parameter uncertainties is important for science-based decision making, long-term stewardship and monitoring network design. We use the recently developed Maximum Likelihood Bayesian Model Averaging (MLBMA) method to assess jointly the uncertainty associated with alternative flow and transport models, and their parameters, at the 300 Area of the DOE Hanford Site in Washington. Eight groundwater flow and transport model alternatives are considered representing various levels of model complexity, e.g., the degree to which they resolve temporal variations in river stage and spatial variations in hydraulic and transport parameters. The eight models are implemented using MODFLOW and MT3DMS in conjunction with the statistical parameter estimation package PEST and its sensitivity routine SENSAN within the framework of GMS (Groundwater Modeling System). Each of the eight flow and transport models is calibrated jointly against site measurements of hydraulic head and concentration. Parameters found to be insensitive to these measurements and measurements found to have negligible effect on model parameters are excluded from the calibration. The relative plausibility of each calibrated model is expressed in terms of a posterior model probability computed on the basis of Kashyap's information criterion KIC. Models having relatively small posterior probabilities are discarded and those with relatively large posterior probabilities are retained to obtain MLBMA predictions of flow and transport at the site. This is done by (a) using the parameter estimates and their covariance matrices to generate numerous Monte Carlo realizations of model parameters; (b) generating corresponding realizations of predicted heads, concentrations and fluxes; (c) computing the mean and variance of these quantities over all realizations; and (d) averaging the latter over all models using their posterior probabilities as weights. We conclude by comparing the predictive

    The TMT first light Adaptive Optics (AO) facility consists of the Narrow Field Infra-Red AO System (NFIRAOS) and the associated Laser Guide Star Facility (LGSF). NFIRAOS is a 60 × 60 laser guide star (LGS) multi-conjugate AO (MCAO) system, which provides uniform, diffraction-limited performance in the J, H, and K bands over 17-30 arc sec diameter fields with 50 per cent sky coverage at the galactic pole, as required to support the TMT science cases. NFIRAOS includes two deformable mirrors, six laser guide star wavefront sensors, and three low-order, infrared, natural guide star wavefront sensors within each client instrument. The first light LGSF system includes six sodium lasers required to generate the NFIRAOS laser guide stars. In this paper, we will provide an update on the progress in designing, modeling and validating the TMT first light AO systems and their components over the last two years. This will include pre-final design and prototyping activities for NFIRAOS, preliminary design and prototyping activities for the LGSF, design and prototyping for the deformable mirrors, fabrication and tests for the visible detectors, benchmarking and comparison of different algorithms and processing architecture for the Real Time Controller (RTC) and development and tests of prototype candidate lasers. Comprehensive and detailed AO modeling is continuing to support the design and development of the first light AO facility. Main modeling topics studied during the last two years include further studies in the area of wavefront error budget, sky coverage, high precision astrometry for the galactic center and other observations, high contrast imaging with NFIRAOS and its first light instruments, Point Spread Function (PSF) reconstruction for LGS MCAO, LGS photon return and sophisticated low order mode temporal filtering.

  20. Conceptual models of the formation of acid-rock drainage at road cuts in Tennessee

    Science.gov (United States)

    Bradley, Michael W.; Worland, Scott; Byl, Tom

    2015-01-01

    Pyrite and other minerals containing sulfur and trace metals occur in several rock formations throughout Middle and East Tennessee. Pyrite (FeS2) weathers in the presence of oxygen and water to form iron hydroxides and sulfuric acid. The weathering and interaction of the acid on the rocks and other minerals at road cuts can result in drainage with low pH (< 4) and high concentrations of trace metals. Acid-rock drainage can cause environmental problems and damage transportation infrastructure. The formation and remediation of acid-drainage from roads cuts has not been researched as thoroughly as acid-mine drainage. The U.S Geological Survey, in cooperation with the Tennessee Department of Transportation, is conducting an investigation to better understand the geologic, hydrologic, and biogeochemical factors that control acid formation at road cuts. Road cuts with the potential for acid-rock drainage were identifed and evaluated in Middle and East Tennessee. The pyrite-bearing formations evaluated were the Chattanooga Shale (Devonian black shale), the Fentress Formation (coal-bearing), and the Precambrian Anakeesta Formation and similar Precambrian rocks. Conceptual models of the formation and transport of acid-rock drainage (ARD) from road cuts were developed based on the results of a literature review, site reconnaissance, and the initial rock and water sampling. The formation of ARD requires a combination of hydrologic, geochemical, and microbial interactions which affect drainage from the site, acidity of the water, and trace metal concentrations. The basic modes of ARD formation from road cuts are; 1 - seeps and springs from pyrite-bearing formations and 2 - runoff over the face of a road cut in a pyrite-bearing formation. Depending on site conditions at road cuts, the basic modes of ARD formation can be altered and the additional modes of ARD formation are; 3 - runoff over and through piles of pyrite-bearing material, either from construction or breakdown

    International Nuclear Information System (INIS)

    The Advanced Neutron Source (ANS) is a world-class research reactor and experimental center for neutron research, presently being designed at the Oak Ridge National Laboratory (ORNL). The reactor consists of a 330-MW(f) highly enriched uranium core, which is cooled, moderated, and reflected with heavy water. When completed, it will be the preeminent ultrahigh neutron flux reactor in the world, with facilities for research programs in biology, materials science, chemistry, fundamental and nuclear physics, and analytical chemistry. Irradiation facilities are provided for a variety of isotope production capabilities, as well as materials irradiation. The ANS reactor design, at the time of this report, has completed the conceptual design phase and entered the advanced conceptual design phase. This report is part of an effort to fully document the analysis methods and results for the conceptual design. It details the methods used to perform heat load calculations on the ANS reactor design, describes the model used, and gives the resulting heat loads in all components of the reactor, in both a differential (by segment) and integral (by component) fashion. These heat load data are provided at three times within the ANS fuel cycle - at beginning (0 days), middle (8.5 days), and end (17 days) of cycle. The remainder of the report is dedicated to this description. In Chapter 2, some necessary background on the reactor design is provided. Chapters 3 and 4 give details of the depletion methods used and revisions to previous MCNP models. Chapter 5 analyzes the results of these calculations, and Chapter 6 provides a summary and conclusions

    A number of uncertainties exist in the hydrogeology of the Hanford Site, and the high costs and risks associated with cleanup of sites contaminated with radioactive wastes requires that the uncertainty associated with alternative remediation decisions must fully reflect the uncertainty associated with these decisions. Prior uncertainty analyses of Hanford groundwater model predictions have focused on uncertainties in model parameters (e.g., hydraulic conductivity) given an assumed conceptual model of hydrogeologic structure. In this study we evaluated predictive uncertainty related to the model structure conceptualization. Our study has focused on two major elements of the hydrogeologic structure of the Hanford Site: the geometry of mud units that occur within the aquifer, and the parameter zonation for hydrologic properties of the uppermost conductive portion of the aquifer. For each structural element, we have developed alternative conceptual models that have been evaluated by inverse modeling. The geometry and continuity of mud units exert a strong influence on groundwater flow and contaminant transport at the site. A detailed study of the spatial distribution of the three mud units was performed using a data set consisting of the presence/absence of each mud unit at several hundred boreholes, as well as the thickness if a mud unit was present. The spatial analysis proceeded in two stages. A series of stochastic simulations of the mud units were prepared using geostatistical methods. The stochastic simulations were numerically ranked and a subset of the best and worst simulations (as determined by the connectedness of the aquifer given the simulated mud distributions) was used as inputs to an inverse model. Inverse modeling was performed using UCODE and a finite element flow and transport code (CFEST) and used to test the fit of over 76,000 observed potentiometric head data for several alternative models of the mud distribution. Those conceptual models included

    This paper illustrates some of the knowledge representation structures and inference procedures proper to a high-level, fully implemented conceptual language, NKRL (Narrative Knowledge Representation Language). The aim is to show how these tools can be used to deal, in a sentiment analysis/opinion mining context, with some common types of human (and non-human) "behaviors". These behaviors correspond, in particular, to the concrete, mutual relationships among human and non-human characters that can be expressed under the form of non-fictional and real-time "narratives" (i.e., as logically and temporally structured sequences of "elementary events").

    K & S operates the largest and one of the most comprehensive Accredited Dosimetry Calibration Laboratories (ADCLs) in the American Association of Physicists in Medicine (AAPM) secondary laboratory system. It offers calibrations covering energies from Grenz-Ray (0.03-mm Al) to cesium-137 and cobalt-60, brachytherapy source and well chamber calibrations for low-activity sources, and, recently, high-dose-rate iridium-192. The present Quality Assurance (QA) program at K & S began with the AAPM Guidelines for Accreditation (Task Group No. 22 and No. 3, 1989) and grew over the past 10 years to include all aspects of providing a private, self-supporting calibration service from a free-standing independent facility. Some aspects of the QA program were prompted by the requirements of the nuclear power industry while other parts were from national consensus standards or the experiences of staff. Redundancy and teamwork are the most important characteristics of this QA program. K & S has participated in a National Institute of Standards and Technology (NIST) measurement quality assurance (MQA) program since 1982, and, in recent years, an ADCL intralaboratory intercomparison was conducted by Task Group 3 of the Radiation Therapy Committee of the AAPM. One measure of the credibility of a QA program is consistent performance on the MQA program and the ADCL intercomparisons over the past 10 years. An equally important measure of the ability of a program to assure quality results is the frequency of reported errors.

    Eckels Anderson, Chessa

    This study contributed to the body of research that supports a holistic model of afterschool learning through the design of an afterschool intervention that benefits elementary school students of low socioeconomic status. This qualitative study evaluated a science focused afterschool curriculum that was designed using principles from Risk and Resiliency Theory, academic motivation theories, science core ideas from the Next Generation Science Standards, and used environmental education philosophy. The research question of this study is: how does an outdoor and STEM based afterschool program impact at-risk students' self-efficacy, belonging and engagement and ability to apply conceptual knowledge of environmental science topics? The study collected information about the participants' affective experiences during the intervention using structured and ethnographic observations and semi-structured interviews. Observations and interviews were coded and analyzed to find patterns in participants' responses. Three participant profiles were developed using the structured observations and ethnographic observations to provide an in depth understanding of the participant experience. The study also assessed the participants' abilities to apply conceptual understanding of the program's science topics by integrating an application of conceptual knowledge task into the curriculum. This task in the form of a participant project was assessed using an adapted version of the Portland Metro STEM Partnership's Application of Conceptual Knowledge Rubric. Results in the study showed that participants demonstrated self-efficacy, a sense of belonging and engagement during the program. Over half of the participants in the study demonstrated a proficient understanding of program concepts. Overall, this holistic afterschool program demonstrated that specific instructional practices and a multi-modal science curriculum helped to support the social and emotional needs of at-risk children.

    Plasma wakefield acceleration has the potential to dramatically shrink the size and cost of particle accelerators. Research at the SLAC National Accelerator Laboratory has demonstrated that plasmas can provide 1,000 times the acceleration in a given distance compared with current technologies. Developing revolutionary and more efficient acceleration techniques that allow for an affordable high-energy collider is the focus of FACET, a National User Facility at SLAC. The existing FACET National User Facility uses part of SLAC’s two-mile-long linear accelerator to generate high-density beams of electrons and positrons. FACET-II is a new test facility to develop advanced acceleration and coherent radiation techniques with high-energy electron and positron beams. It is the only facility in the world with high energy positron beams. FACET-II provides a major upgrade over current FACET capabilities and the breadth of the potential research program makes it truly unique. It will synergistically pursue accelerator science that is vital to the future of both advanced acceleration techniques for High Energy Physics, ultra-high brightness beams for Basic Energy Science, and novel radiation sources for a wide variety of applications. The design parameters for FACET-II are set by the requirements of the plasma wakefield experimental program. To drive the plasma wakefield requires a high peak current, in excess of 10kA. To reach this peak current, the electron and positron design bunch size is 10μ by 10μ transversely with a bunch length of 10μ. This is more than 200 times better than what has been achieved at the existing FACET. The beam energy is 10 GeV, set by the Linac length available and the repetition rate is up to 30 Hz. The FACET-II project is scheduled to be constructed in three major stages. Components of the project discussed in detail include the following: electron injector, bunch compressors and linac, the positron system, the Sector 20 sailboat and W chicanes

    2011-06-01

    Full Text Available Abstract Background Tobacco smoke exposure (TSE is a serious threat to child health. Roughly 40% of children worldwide are exposed to tobacco smoke, and the very young are often "captive smokers" in homes in which others smoke. The goal of this research project is to develop and evaluate an intervention to reduce young child tobacco smoke exposure. The objective of this paper is to document our approach to building the intervention, to describe the planned intervention, and to explore the conceptual issues regarding the intervention and its evaluation. Methods/Design This project is being developed using an iterative approach. We are currently in the middle of Stage 1. In this first stage, Intervention Development, we have already conducted a comprehensive search of the professional literature and internet resources, consulted with experts in the field, and conducted several Design Workshops. The planned intervention consists of parental group support therapy, a website to allow use of an "online/offline" approach, involvement of pediatricians, use of a video simulation game ("Dr. Cruz" to teach parents about child TSE, and personalized biochemical feedback on exposure levels. As part of this stage we will draw on a social marketing approach. We plan to use in-depth interviews and focus groups in order to identify barriers for behavior change, and to test the acceptability of program components. In Stage II, we plan to pilot the planned intervention with 5-10 groups of 10 parents each. In Stage III, we plan to implement and evaluate the intervention using a cluster randomized controlled trial with an estimated 540 participants. Discussion The major challenges in this research are twofold: building an effective intervention and measuring the effects of the intervention. Creation of an effective intervention to protect children from TSE is a challenging but sorely needed public health endeavor. We hope that our approach will contribute to building

    The Oak Ridge National Laboratory (ORNL) is a US Department of Energy (DOE) facility that is managed by UT-Battelle, LLC. In February 2006, DOE promulgated worker safety and health regulations to govern contractor activities at DOE sites. These regulations, which are provided in 10 CFR 851, Worker Safety and Health Program, establish requirements for worker safety and health program that reduce or prevent occupational injuries, illnesses, and accidental losses by providing DOE contractors and their workers with safe and healthful workplaces at DOE sites. The regulations state that contractors must achieve compliance no later than May 25, 2007. According to 10 CFR 851, Subpart C, Specific Program Requirements, contractors must have a structured approach to their worker safety and health programs that at a minimum includes provisions for pressure safety. In implementing the structured approach for pressure safety, contractors must establish safety policies and procedures to ensure that pressure systems are designed, fabricated, tested, inspected, maintained, repaired, and operated by trained, qualified personnel in accordance with applicable sound engineering principles. In addition, contractors must ensure that all pressure vessels, boilers, air receivers, and supporting piping systems conform to (1) applicable American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (2004) Sections I through XII, including applicable code cases; (2) applicable ASME B31 piping codes; and (3) the strictest applicable state and local codes. When national consensus codes are not applicable because of pressure range, vessel geometry, use of special materials, etc., contractors must implement measures to provide equivalent protection and ensure a level of safety greater than or equal to the level of protection afforded by the ASME or applicable state or local codes. This report documents the work performed to address legacy pressure vessel deficiencies and comply

    Preliminary selection criteria have been developed, peer-reviewed, and applied to a field of 41 candidate materials to choose three alloys for further consideration during the advanced conceptual design phase of waste package development for a potential high level nuclear waste repository at Yucca Mountain, Nevada. These three alloys are titanium grade 12, Alloy C-4, and Alloy 825. These selections are specific to the particular conceptual design outlined in the Site Characterization Plan. Other design concepts that may be considered in the advanced conceptual design phase may favor other materials choices.

    Historically, uranium was disposed in waste solutions of varying waste chemistry at the Hanford Site Central Plateau. The character of how uranium was distributed in the vadose zone during disposal, how it has continued to migrate through the vadose zone, and the magnitude of potential impacts on groundwater are strongly influenced by geochemical reactions in the vadose zone. These geochemical reactions can be significantly influenced by the disposed-waste chemistry near the disposal location. This report provides conceptual models and supporting information to describe uranium fate and transport in the vadose zone for both acidic and alkaline wastes discharged at a substantial number of waste sites in the Hanford Site Central Plateau. The conceptual models include consideration of how co-disposed acidic or alkaline fluids influence uranium mobility in terms of induced dissolution/precipitation reactions and changes in uranium sorption with a focus on the conditions near the disposal site. This information, when combined with the extensive information describing uranium fate and transport at near background pH conditions, enables focused characterization to support effective fate and transport estimates for uranium in the subsurface.

    International Nuclear Information System (INIS)

    A research program for the production and utilization of iodine-123 is described. From 1979 to 1982 the spallation of elemental cesium by 500-MeV protons was used to provide 100 mCi/hr at the end of bombardment (EOB). Contaminants were 3% iodine-125 and 0.15% tellurium-121 at EOB + 36 hr. The material from weekly runs was used by remote clinics in Canada for evaluation as a radiochemical and for labeling studies. A new facility at TRIUMF will be operational in 1983 to produce iodine-123 by the (p,5n) reaction

    Gas turbines in industrial and utility applications can help meet future national and worldwide power generation requirements. Turbine systems burning natural gas offer environmentally sound and economical power generation and cogeneration. Since U.S. demand alone will require up to 15 gigawatts per year of new and replacement capacity after the year 2000, the availability of Advanced Turbine Systems (ATS) to fill a share of this need will save significant amounts of fuel and benefit the environment. Implementation of the ATS Program will also keep U.S. manufacturers on the cutting ledge of turbine technology for power generation applications and enhance the nation`s economic competitiveness.

    The Idaho INEL Oversight Program, in association with the University of Idaho, Idaho Geological Survey, Boise State University, and Idaho State University, developed a research program to determine the hydraulic properties of the Snake River Plain aquifer and characterize the vertical distribution of contaminants. A straddle-packer was deployed in four observation wells near the Idaho Chemical Processing Plant at the Idaho National Engineering Laboratory. Pressure transducers mounted in the straddle-packer assembly were used to monitor the response of the Snake River Plain aquifer to pumping at the ICPP production wells, located 2600 to 4200 feet from the observation wells. The time-drawdown data from these tests were used to evaluate various conceptual models of the aquifer. Aquifer properties were estimated by matching time-drawdown data to type curves for partially penetrating wells in an unconfined aquifer. This approach assumes a homogeneous and isotropic aquifer. The hydraulic properties of the aquifer obtained from the type curve analyses were: (1) Storativity = 3 x 10{sup -5}, (2) Specific Yield = 0.01, (3) Transmissivity = 740 ft{sup 2}/min, (4) Anisotropy (Kv:Kh)= 1:360.

    Video analysis, using the program Tracker (Open Source Physics), in the educational process introduces a new creative method of teaching physics and makes natural sciences more interesting for students. This way of exploring the laws of nature can amaze students because this illustrative and interactive educational software inspires them to think creatively, improves their performance and helps them in studying physics. This paper deals with increasing the key competencies in engineering by analysing real-life situation videos - physical problems - by means of video analysis and the modelling tools using the program Tracker and simulations of physical phenomena from The Physics Education Technology (PhET™) Project (VAS method of problem tasks). The statistical testing using the t-test confirmed the significance of the differences in the knowledge of the experimental and control groups, which were the result of interactive method application.

    beginning, the design studies at Jefferson Lab have focused on achieving high collider performance, particularly ultrahigh luminosities up to 10{sup 34} cm{sup -2}s{sup -1} per detector with large acceptance, while maintaining high polarization for both the electron and light-ion beams. These are the two key performance requirements of a future electron-ion collider facility as articulated by the NSAC Long Range Plan. In MEIC, a new ion complex is designed specifically to deliver ion beams that match the high bunch repetition and highly polarized electron beam from CEBAF. During the last two years, both development of the science case and optimization of the machine design point toward a medium-energy electron-ion collider as the topmost goal for Jefferson Lab. The MEIC, with relatively compact collider rings, can deliver a luminosity above 10{sup 34} cm{sup -2}s{sup -1} at a center-of-mass energy up to 65 GeV. It offers an electron energy up to 11 GeV, a proton energy up to 100 GeV, and corresponding energies per nucleon for heavy ions with the same magnetic rigidity. This design choice balances the scope of the science program, collider capabilities, accelerator technology innovation, and total project cost. An energy upgrade could be implemented in the future by adding two large collider rings housed in another large tunnel to push the center-of-mass energy up to or exceeding 140 GeV. After careful consideration of an alternative electron energy recovery linac on ion storage ring approach, a ring-ring collider scenario at high bunch repetition frequency was found to offer fully competitive performance while eliminating the uncertainties of challenging R&D on ampere-class polarized electron sources and many-pass energy-recovery linacs (ERLs). The essential new elements of an MEIC facility at Jefferson Lab are an electron storage ring and an entirely new, modern ion acceleration and storage complex. For the high-current electron collider ring, the upgraded 12 GeV CEBAF SRF

    The Zurich IMaging POLarimeter (ZIMPOL) developed at ETH Zurich and installed permanently at the Gregory Coude Telescope at Istituto Ricerche Solari Locarno (IRSOL) allows a polarimetric precision down to 10^-5 to be reached. This makes it possible to perform several accurate spectro-polarimetric measurements of scattering polarization and to investigate solar magnetic fields through the signatures of the Hanle and Zeeman effects. The research programs are currently being extended to monochromatic imaging of the Stokes vector with a recently installed Fabry-Perot rapidly tunable filter system with a narrow pass band of about 30mA. The spatial resolution is being improved by the installation of an Adaptive Optics system.

  8. Embodied Conceptual Combination

    2010-11-01

    Full Text Available Conceptual combination research investigates the processes involved in creating new meaning from old referents. It is therefore essential that embodied theories of cognition are able to explain this constructive ability and predict the resultant behaviour. However, by failing to take an embodied or grounded view of the conceptual system, existing theories of conceptual combination cannot account for the role of perceptual, motor and affective information in conceptual combination. In the present paper, we propose the Embodied Conceptual Combination (ECCo model to address this oversight. In ECCo, conceptual combination is the result of the interaction of the linguistic and simulation systems, such that linguistic distributional information guides or facilitates the combination process, but the new concept is fundamentally a situated, simulated entity. So, for example, a cactus beetle is represented as a multimodal simulation that includes visual (e.g., the shiny appearance of a beetle and haptic (e.g., the prickliness of the cactus information, all situated in the broader location of a desert environment under a hot sun, and with (at least for some people an element of creepy-crawly revulsion. The ECCo theory differentiates interpretations according to whether the constituent concepts are destructively, or nondestructively, combined in the situated simulation. We compare ECCo to other theories of conceptual combination, and discuss how it accounts for classic effects in the literature.

  9. The research program at SIS/ESR

    International Nuclear Information System (INIS)

    A varied research program is currently in preparation for the expanded facility. Above one hundred experiments have been proposed following a call for proposals about 1 1/2 year ago, and have been reviewed by an international science committee. About half of the proposals were aimed at research in nuclear and nuclear-matter physics. These are discussed in more detail in the present overview. In addition, about 25% of the proposals were in the area of atomic physics, planning to make use of the capability of the new facility to strip even the heaviest ions into the innermost shells, with the additional possibility of subsequent cooling and deceleration. Biological research, utilizing the larger range of ions at elevated energies and thus deeper penetration and also irradiation in atmosphere, represented about 15% of the proposals; the rest was divided among various projects of applied research.

(1) SINQ LBE target: The phase II study program for SINQ is planned. A new LBE loop is being constructed. The study has the following three objectives: (a) Pump study - design work on an electromagnetic pump to be integrated into the target. (b) Heat pipe performance test - the use of heat pipes as an additional component of the target cooling system is being considered, and it may be a way to futher decouple the liquid metal and water coolant loops. (c) Mixed convection experiment - in order to find an optimal configuration of the additional flow guide for window cooling, mixed convection around the window is to be studied. The experiment will be started using water and then with LBE. (2) ESS Mercury target: For ESS target study, the following experimental studies are planned, some of which are exampled by trial experiments. (a) Flow around the window: Flow mapping around the hemi-cylindrical window will be made for optimising the flow channels and structures, (b) Geometry optimisation for minimizing a recirculation zone behind the edge of the flow separator, (c) Flow induced vibration and buckling problem for a optimised structure of the flow separator and (d) Gas-liquid two-phase flow will be studied by starting to establish the new experimental method of measuring various kinds of two-phase flow characteristics.

    Proposed by Prof. Ganchang Wang in 1964 and officially started in 1976 the ICF Program at CAEP includes research on every aspect of ICF science and technology: high power and energy laser technology, target fabrication, diagnostics, target physics, and potential applications. Two solid-state lasers have been operated since the middle of the last decade. The most of research on target physics has been focused on indirect-drive approach, covering laser-plasma coupling, parametric instabilities and suprathermal electrons, x-ray conversion and transport, plasma energetics, ablation, hydrodynamic instabilities. Neutron production experiments were conducted successfully on the Shenguang facility (2x800 J, 1 ns, and 1.053 μm) with radiation-driven targets in 1990. In addition, equation of state experiments have been performed using both laser- and x-ray-driven targets for Fe, Cu, and glass. Furthermore, a much bigger laser facility is now being considered. copyright 1996 American Institute of Physics

  15. Graphical programming at Sandia National Laboratories

    International Nuclear Information System (INIS)

    Sandia has developed an advanced operational control system approach, called Graphical Programming, to design, program, and operate robotic systems. The Graphical Programming approach produces robot systems that are faster to develop and use, safer in operation, and cheaper overall than altemative teleoperation or autonomous robot control systems. Graphical Programming also provides an efficient and easy-to-use interface to traditional robot systems for use in setup and programming tasks. This paper provides an overview of the Graphical Programming approach and lists key features of Graphical Programming systems. Graphical Programming uses 3-D visualization and simulation software with intuitive operator interfaces for the programming and control of complex robotic systems. Graphical Programming Supervisor software modules allow an operator to command and simulate complex tasks in a graphic preview mode and, when acceptable, command the actual robots and monitor their motions with the graphic system. Graphical Programming Supervisors maintain registration with the real world and allow the robot to perform tasks that cannot be accurately represented with models alone by using a combination of model and sensor-based control

  16. Turbulence Spectra for Boundary-Layer Winds in Tropical Cyclones: A Conceptual Framework and Field Measurements at Coastlines

    Li, Lixiao; Kareem, Ahsan; Hunt, Julian; Xiao, Yiqing; Zhou, Chaoying; Song, Lili

    A conceptual model is proposed for the characteristic sub-ranges in the velocity and temperature spectra in the boundary layer of tropical cyclones (hurricanes or typhoons). The model is based on observations and computation of radial and vertical profiles of the mean flow and turbulence, and on the interpretation of eddy mechanisms determined by shear (namely roll and streak structures near the surface), convection, rotation, blocking and sheltering effects at the ground/sea surface and in internal shear layers. The significant sub-ranges, as the frequency increases, are associated with larger energy containing eddies, shear and blocking, inertial transfer between large and small scales, and intense small-scale eddies generated near the surface caused by waves, coastal roughness change, and the buoyancy force associated with the evaporation of spray droplets. These sub-ranges vary with the locations at which the spectra are measured, i.e. the level in relation to the height of the peak mean velocity and the depth of the boundary layer, and the radius in relation to the eyewall radius and the outer-vortex radius . For two tropical cyclones (Nuri and Hagupit), experimental data were analyzed. Spectra were measured where is near to and using four 1-h long datasets at coastal towers, at 10- and 60-m heights for tropical cyclone Nuri, and at 60-m height for tropical cyclone Hagupit at the south China coast. The field measurements of spectra within the boundary layer show significant sub-ranges of self-similar energy spectra (lying between the length scale 1,000 m and the smallest scales less than 40 m) that are consistent with the above conceptual model of the surface layer. However, with very high wind speeds near the eyewall, the energy of the independently generated intense surface eddy motions, associated with surface waves and water droplets in the airflow, greatly exceeds the energies of the small scales in the inertial sub-range of the boundary layer, over

    The Laser Communication Relay Demonstration will feature a geostationary satellite communicating via optical links to multiple ground stations. The first ground station (GS-1) is the 1m OCTL telescope at Table Mountain in California. The optical link will utilize pulse position modulation (PPM) and differential phase shift keying (DPSK) protocols. The DPSK link necessitates that adaptive optics (AO) be used to relay the incoming beam into the single mode fiber that is the input of the modem. The GS-1 AO system will have two MEMS Deformable mirrors to achieve the needed actuator density and stroke limit. The AO system will sense the aberrations with a Shack-Hartmann wavefront sensor using the light from the communication link's 1.55 microns laser to close the loop. The system will operate day and night. The system's software will be based on heritage software from the Palm 3000 AO system, reducing risk and cost. The AO system is being designed to work at r(sub 0) greater than 3.3 cm (measured at 500 nm and zenith) and at elevations greater than 20deg above the horizon. In our worst case operating conditions we expect to achieve Strehl ratios of over 70% (at 1.55 microns), which should couple 57% of the light into the single mode DPSK fiber. This paper describes the conceptual design of the AO system, predicted performance and discusses some of the trades that were conducted during the design process.

  18. What binds quarks together at different momentum scales? A conceptual scenario

    Directory of Open Access Journals (Sweden)

    N.G. Stefanis

    2014-11-01

    Full Text Available The binding effects of quarks within hadrons are discussed in terms of the pion distribution amplitude over longitudinal momentum fractions. To understand the behavior of this quantity at different momentum scales, the concept of synchronization in complex systems has been employed. It is argued that at low momentum scales, the quarks get correlated by nonlocal quark/gluon condensates that cause an endpoint-suppressed, mainly bimodal structure of the pion distribution amplitude inferred from a sum-rule analysis. The mass generation mechanism, within the framework of Dyson–Schwinger equations, and evolution effects pull these two peaks back to the center to form at Q2→∞ the asymptotic distribution amplitude which represents the most synchronized q¯q state.

  19. Conceptual frameworks in astronomy

    2016-06-01

    How to evaluate students' astronomy understanding is still an open question. Even though some methods and tools to help students have already been developed, the sources of students' difficulties and misunderstanding in astronomy is still unclear. This paper presents an investigation of the development of conceptual systems in astronomy by 50 engineering students, as a result of learning a general course on astronomy. A special tool called Conceptual Frameworks in Astronomy (CFA) that was initially used in 1989, was adapted to gather data for the present research. In its new version, the tool included 23 questions, and five to six optional answers were given for each question. Each of the answers was characterized by one of the four conceptual astronomical frameworks: pre-scientific, geocentric, heliocentric and sidereal or scientific. The paper describes the development of the tool and discusses its validity and reliability. Using the CFA we were able to identify the conceptual frameworks of the students at the beginning of the course and at its end. CFA enabled us to evaluate the paradigmatic change of students following the course and also the extent of the general improvement in astronomical knowledge. It was found that the measure of the students’ improvement (gain index) was g = 0.37. Approximately 45% of the students in the course improved their understanding of conceptual frameworks in astronomy and 26% deepened their understanding of the heliocentric or sidereal conceptual frameworks.

  20. Feasibility and conceptual design of a C.W. positron source at CEBAF

    Energy Technology Data Exchange (ETDEWEB)

    2010-08-01

    A feasibility study of a CW positron source for the 12 GeV upgrade at Jefferson Lab (JLAB) is provided. The proposed ≥ 100 nA Continuous Wave (CW) positron source at JLAB has several unique and challenging characteristics: high current incident electron beam at 126 MeV with a high beam power (up to a MW); CW e- beam and CW e+ production. The multiple scattering is a dominant process when creating e+ in a target, which results a large phase space area of the emitted positrons. An admittance study was done at CEBAF to find the maximum phase space area, which is tolerated in the machine. The measured geometrical transverse admittance (A) were Ax =10 and Ay = 5 mm∙mrad at the injector. Energy spread measurement was also done at the ARC1. The fractional spread limit in the ARC1 was measured as δ = 3×10-3 at 653 MeV. By using the optimized results and the CEBAF parameters, three positron injector configurations are proposed; Combined Function Magnet, Two-Dipole and Microtron Dipole configurations. With the assumptions made, by using 126 MeV Ⓧ10 mA e- beam impinging on a 2 mm W target with a 100 μm spot size, we can get up to 3 μA useful e+ current at the North Linac connection. One of the biggest challenges is the target design, which the deposited power is about 60 kW. ILC designs project power deposition up to 13 kW, which would allow the creation of a e+ beam of up to 650 nA otherwise. The results of analytic and monte carlo simulations of the positron production, capture and acceleration are presented. For the target design, a review is presented of solutions for the high power production target. Portions of this dissertation work have been published in two conference proceedings.

    The potential for a superconducting proton linac (SPL) at CERN started to be seriously considered at the end of the 1990s. In the first conceptual design report (CDR), published in 2000 [1], most of the 352 MHz RF equipment from LEP was re-used in an 800 m long linac, and the proton beam energy was limited to 2.2 GeV. During the following years, the design was revisited and optimized to better match the needs of a high-power proton driver for neutrino physics. The result was a more compact (470 m long) accelerator capable of delivering 5 MW of beam power at 3.5 GeV, using state-of-the-art superconducting RF cavities at 704 MHz. It was described in a second CDR, published in 2006 [2]. Soon afterwards, when preparation for increasing the luminosity of the LHC by an order of magnitude beyond nominal became an important concern, a low-power SPL (LP-SPL) was studied as a key component in the renovation of the LHC injector complex. The combination of a 4 GeV LP-SPL injecting into a new 50 GeV synchrotron (PS2) was ...

    2015-12-01

    The underground Hard Rock Laboratory (HRL) at Äspö, Sweden, is located in granitic rock and dedicated to investigations concerning deep geological disposal of radioactive waste. Several in-situ experiments have been performed in the HRL, among them the recent Buffer-Rock Interaction Experiment (BRIE) and, on a much larger scale, the long-term Prototype Repository (PR) experiment.Interpretation of such experiments requires a profound understanding of the groundwater flow system. Often assumed is a conceptual model where the so-called "intact rock" is interspersed with stochastically distributed fractures. It is also a common assumption, though, that fractures in granite exist on all length-scales implying that the hydraulically relevant rock porosity is basically made up of micro fractures. The conceptual approach of GRS' groundwater flow code d3f thus appeared to be fitting where large fractures are represented discretely by lower-dimensional features while the remaining set of smaller fractures - also called "background fractures" - is assumed to act like an additional homogeneous continuum besides what is believed to be the undisturbed matrix. This approach was applied to a hydraulic model of the BRIE in a cube-like domain of 40 m side length including drifts, boreholes and three intersecting large fractures. According to observations at the underground rock laboratories Stripa and the HRL a narrow zone of reduced permeability - called "skin" - was additionally arranged around all geotechnical openings. Calibration of the model resulted in a considerable increase of matrix permeability due to adding the effect of the background fractures. To check the validity of this approach the calibrated data for the BRIE were applied to a model for the PR which is also located in the HRL but at quite some distance. The related brick-shaped model domain has a size of 200 m x 150 m x 50 m. Fitting the calculated outflow from the rock to the measured outflow distribution

  6. Large superconductors and joints for fusion magnets: From conceptual design to testing at full scale

    International Nuclear Information System (INIS)

    A new kind of superconductor, using the cable-in-conduit concept, is emerging, mainly in the context of fusion activity. At present no large Nb3Sn magnet in the world is operating using this concept. The difficulty of this technology, which has now been studied for 20 years, is that it requires major advances in several interconnected new fields, such as handling a large number (1000) of superconducting strands, high current conductors (50 kA), forced flow cryogenics, Nb3Sn technology, low loss conductors in pulsed operation, high current connections and high voltage insulation (10 kV), as well as demonstration of its economical and industrial feasibility. CEA has been very much involved during the past ten years in this development, which took place in the framework of the NET and ITER technological programmes. One major milestone was reached in 1998-1999 with the successful tests by Euratom-CEA of three full size conductor and connection samples in the SULTAN facility in Switzerland. (author)

    KAERI has been developing pyro-process facilities for a dry processing research of spent fuel about ten years since 1997. A hot cell facility, named the ACPF-Advanced spent fuel Conditioning Process Facility, for the demonstration of a head-end part of pyro-process was developed at November 2005. An inactive demonstration facility for the integrated pyro-process, named PRIDE-pyro-process Integrated inactive Demonstration, has been developing since 2007. The PRIDE facility consists of two cells: one is an air environment cell and another one is an argon environment cell. This facility includes several pyro-process equipment, such as a decladding/voloxidation device, a powder mixing device, an electro-reduction equipment, an electro-refining equipment, an electro-winning equipment, a Cd distillation equipment, a waste salt regeneration and solidification equipment, a salt distillation equipment, etc. In the cell and on the wall, some cell equipment, such as one cell crane, one BTDSM (Bridge Transported Dual arm Servo Manipulator), two HMSM (Horizontally Moving dual arm Servo Manipulator) will be also installed. This facility will be utilized to obtain the basic requirements for an engineering scale pyro-process facility in which the spent fuels from power reactors can be treated. (authors)

    Between main shutdowns of the ITER machine, in-vessel components and Iter Remote Maintenance System (IRMS) are transferred between the Tokamak complex and the Hot Cell Facility using different types of sealed casks. Transfer Casks have different physical interfaces with the Vacuum Vessel, which need to be the same at the docking stations of the HCF. It means that in-vessel components and IRMS are cleaned in the same cells, which is in fact not convenient. Furthermore, logistic studies showed that the use rate of the cells is very inhomogeneous. In order to have dedicated cell for decontamination of Remote Handling tools, in order to increase the operability efficiency and to removes the hot cell docking operation from the critical path, the concept of a universal docking station has been investigated. Based on an existing design, the work was focused on a review of requirements, the re-design and the integration within the HCF layout. The universal docking station has been proposed and is now integrated in HCF design.

    Full Text Available The article is aimed at studying the current trends of regulatory policy in the global energy market and identifying potent ways for energy efficiency growth in terms of the Ukrainian economy. An analysis of the main trends of energy policy development in the world has been carried out and a priority direction for the development of Ukrainian energy on the basis of the biofuel industry has been determined. The article substantiates actuality of the matter that one of the main directions of overcoming the energy crisis in Ukraine, along with ensuring recovery and sustainable growth of the gross domestic product, is transition to the industrial use of biofuels. The process of production and consumption of biofuels must be seen as a means to raise the level of decentralization, while ensuring energy sources. It is determined that the State must provide information support for producers of biofuels, defining their market range and encouraging beneficial business partners. Increased production of biofuels in Ukraine will serve as a fundamental factor in achieving international competitiveness of the national economy, as well as its growth on innovation basis.

    The TREK program consists of a series of experiments that have been proposed to use the new, recently commissioned kaon beamline K1.1BR at the new J-PARC Hadron Facility in Japan. A beam of low-energy positively charged kaons will be stopped, and their decays observed with a large acceptance toroidal spectrometer capable of tracking charged particles with high resolution, combined with a photon calorimeter and additional instrumentation with muon polarimeters. The first two experiments, requiring less beam intensity, aim to test lepton universality in the Ke2/Kμ2 ratio with 0.2% statistical uncertainty, and to search for heavy sterile neutrinos in two-body kaon decays. Ultimately, the Time Reversal Experiment with Kaons (TREK) aims to find New Physics beyond the Standard Model by a precision measurement of the T-violating transverse polarization PT of muons in the K+μ3 decay of stopped kaons with a sensitivity of 10-4.

    As stated at the beginning of this paper conclusions reached thus far cannot be discussed in this paper. However, a great deal of information is available for examination.EPA displayed its ability to coordinate widely separated laboratories, both Federal and private, into a smooth working team in a very short period of time. A very comprehensive study plan was also developed and implemented quickly. EPA was fortunate to have already had GCA under contract when the emergency arose. In no small part the success of the field effort was due to the managerial and technical abilities of the GCA team.Within a period of 6 weeks a plan was developed, a prime contractor retained, subcontractors hired, and field activities begun. Within a period of 3 months in excess of 8600 field samples were collected and over 12,000 field and QC samples were analyzed. During this same period 2 major data systems were developed, debugged, and placed into operation.In short this EPA project was probably the most comprehensive multimedia field project ever attempted by EPA and certainly the data is being subjected to the most strenuous quality control measures ever imposed by this Agency. The entire program is presently under peer review and the results are being prepared for publication by EPA Headquarters.

    In the framework of the SR-Site safety assessment, a conceptual and numerical modelling of radionuclide reactive transport in near-surface systems (including till and clay systems) at Forsmark has been carried out. The objective was to evaluate the retention capacity of the near-surface systems, composed of Quaternary deposits, which would be the last natural barrier for an eventual radionuclide release from the deep repository prior to reaching the biosphere. The studied radionuclides are 14C, 129I, 36Cl, 94Nb, 59Ni, 93Mo, 79Se, 99Tc, 230Th, 90Sr, 226Ra, 135Cs and U. Conceptual description and numerical simulations of radionuclide reactive transport show that cation exchange and surface complexation on illite are active processes for the retention of several radionuclides (U, Th, Ni, Cs, Sr, Ra). Surface complexation on iron hydroxide is an active process in the till system, able to effectively retain U and Ni. Another retention process of importance is the incorporation of the radionuclides into mineral phases, either by the precipitation of pure phases or solid solutions. Quantitative modelling has been useful to illustrate the incorporation of C and Sr in the carbonate solid solution in the considered model domains (till and clay), as well as the precipitation of uraninite in the clay sediments and the precipitation of native selenium and radiobarite in the till. Other mineral phases that could, a priori, retain U, Se, Nb and Tc do not precipitate in the simulations, either due to the pH-Eh conditions and/or because the dissolved concentration of the element is not high enough under the considered simulation conditions. It is important to keep in mind that changes in these parameters and in the boundary conditions could modify the predicted behaviour of these elements. The radionuclides that are most significantly retarded are Th, Ni and Cs, mainly through sorption onto illite. Therefore, if the amount of illite (or available sorption sites) decreases, the

    Global biogeochemical cycles have been deeply modified by human activities in recent decades. But detailed studies analyzing the influence of current economic and social organizations on global biogeochemical cycles within a system perspective are still required. Country level offers a relevant scale for assessing nutrient management and identifying key driving forces and possible leaks in the nutrient cycle. Conceptual modeling helps to quantify nutrient flows within the country and we developed such an approach for France. France is a typical Western European country with intensive agriculture, trade and an affluent diet, all of which may increase internal and external P flows. Phosphorus (P) was taken as a case study because phosphate rock is a non-renewable resource which future availability is becoming increasingly bleak. A conceptual model of major P flows at the country scale was designed. France was divided into agriculture, industry, domestic, import and export sectors, and each of these sectors was further divided into compartments. A total of 25 internal and eight external P flows were identified and quantified on a yearly basis for a period of 16 years (from 1990 to 2006) in order to understand long-term P flows. All the P flows were quantified using the substance flow analysis principle. The results showed that the industrial sector remained the largest contributor to P flows in France, followed by the agriculture and domestic sectors. Soil P balance was positive. However, a positive P balance of 18 kg P ha-1 in 1990 was reduced to 4 kg P ha-1 in 2006, mainly due to the reduced application of inorganic P fertilizer. The overall country scale P balance was positive, whereas half of this additional P was lost to the environment mainly through the landfilling of municipal and industrial waste, disposal of treated wastewater from which P was partially removed, and P losses from agricultural soils though erosion and leaching. Consequences for global P

    2012-10-01

    Public accountability has re-emerged as a top priority for health systems all over the world, and particularly in developing countries where governments have often failed to provide adequate public sector services for their citizens. One approach to strengthening public accountability is through direct involvement of clients, users or the general public in health delivery, here termed 'community accountability'. The potential benefits of community accountability, both as an end in itself and as a means of improving health services, have led to significant resources being invested by governments and non-governmental organizations. Data are now needed on the implementation and impact of these initiatives on the ground. A search of PubMed using a systematic approach, supplemented by a hand search of key websites, identified 21 papers from low- or middle-income countries describing at least one measure to enhance community accountability that was linked with peripheral facilities. Mechanisms covered included committees and groups (n = 19), public report cards (n = 1) and patients' rights charters (n = 1). In this paper we summarize the data presented in these papers, including impact, and factors influencing impact, and conclude by commenting on the methods used, and the issues they raise. We highlight that the international interest in community accountability mechanisms linked to peripheral facilities has not been matched by empirical data, and present a conceptual framework and a set of ideas that might contribute to future studies.

    Geologic and hydrologic data collected by the United States Geological Survey (USGS) are used to evaluate the existing ground water monitoring well network completed in the upper portion of the Snake River Plain aquifer (SRPA) beneath the Idaho Chemical Processing Plant (ICPP). The USGS data analyzed and compared in this study include: (a) lithologic, geophysical, and stratigraphic information, including the conceptual geologic models intrawell, ground water flow measurement (Tracejector tests) and (c) dedicated, submersible, sampling group elevations. Qualitative evaluation of these data indicate that the upper portion of the SRPA is both heterogeneous and anisotropic at the scale of the ICPP monitoring well network. Tracejector test results indicate that the hydraulic interconnection and spatial configuration of water-producing zones is extremely complex within the upper portion of the SRPA. The majority of ICPP monitoring wells currently are equipped to sample ground water only the upper lithostratigraphic intervals of the SRPA, primarily basalt flow groups E, EF, and F. Depth-specific hydrogeochemical sampling and analysis are necessary to determine if ground water quality varies significantly between the various lithostratigraphic units adjacent to individual sampling pumps

    This paper provides an overview of Systems Engineering as it is applied in a conceptual design space systems department at the National Aeronautics and Space Administration (NASA) Marshall Spaceflight Center (MSFC) Advanced Concepts Office (ACO). Engineering work performed in the NASA MFSC's ACO is targeted toward the Exploratory Research and Concepts Development life cycle stages, as defined in the International Council on Systems Engineering (INCOSE) System Engineering Handbook. This paper addresses three ACO Systems Engineering tools that correspond to three INCOSE Technical Processes: Stakeholder Requirements Definition, Requirements Analysis, and Integration, as well as one Project Process Risk Management. These processes are used to facilitate, streamline, and manage systems engineering processes tailored for the earliest two life cycle stages, which is the environment in which ACO engineers work. The role of systems engineers and systems engineering as performed in ACO is explored in this paper. The need for tailoring Systems Engineering processes, tools, and products in the ever-changing engineering services ACO provides to its customers is addressed.

    Full Text Available The nuclear data program at the Rensselaer Polytechnic Institute (RPI is centered around a 60 MeV pulsed electron Linear Accelerator (LINAC configured to deliver pulsed neutron beams. The LINAC electron pulse width can vary between 5 ns and 5 us, a repetition rate of 1–500 pulses per second and neutron yield of up to 1013 n/s. Over the years several experimental setups and techniques were developed to enable a variety of measurement capabilities. The experiments cover the energy range from 0.001 eV to 20 MeV and included neutron transmission, capture, scattering and fission measurements. The facility is also equipped with a Lead Slowing-Down Spectrometer (LSDS producing a high neutron flux that is used for simultaneous measurements of the fission cross section and fission fragment mass and energy distributions. Detectors for (n, alpha and (n, p cross section measurements using the LSDS were also developed and measurements of (n, alpha cross section were completed. The high neutron flux inside the LSDS enables measurements on small samples (sub micrograms or samples with small cross section (sub millibarns. In order to fully utilize the capabilities of the facility, several measurement techniques were developed; high accuracy (<1% total cross sections were measured using iron and uranium filtered neutron beams. A system for fast neutron scattering measurements using an array of liquid scintillators and a digital data acquisition system was recently developed and used for several measurements and is now being adapted for fission neutron studies. Methods for simultaneous measurements of fission and capture cross sections using the RPI multiplicity detector are under development and new modular detectors for both fast and resonance region neutron detection were developed and deployed. These developments result in numerous measurements on different materials and provide input to improved evaluated nuclear data libraries and thus help

    National Security Technologies, LLC, initiated an evaluation of treatment technologies that they would manage and operate as part of the mixed low-level waste (MLLW) disposal facilities at the Nevada National Security Site (NNSS). The NNSS Disposal Facility has been receiving radioactive waste from the U.S. Department of Energy (DOE) complex since the 1960s, and since 2005 the NNSS Disposal Facility has been receiving radioactive and MLLW for disposal only. In accordance with the Resource Conservation and Recovery Act (RCRA), all mixed waste must meet land disposal restrictions (LDRs) prior to disposal. Compliance with LDRs is attained through treatment of the waste to mitigate the characteristics of the listed waste hazard. Presently, most generators utilize commercial capacity for waste treatment prior to shipment to the NNSS Disposal Facility. The objectives of this evaluation are to provide a conceptual study of waste treatment needs (i.e., demand), identify potential waste treatment technologies to meet demand, and analyze implementation considerations for initiating MLLW treatment capacity at the NNSS Disposal Facility. A review of DOE complex waste generation forecast data indicates that current and future Departmental demand for mixed waste treatment capacity will remain steady and strong. Analysis and screening of over 30 treatment technologies narrowed the field of treatment technologies to four: • Macroencapsulation • Stabilization/microencapsulation • Sort and segregation • Bench-scale mercury amalgamation The analysis of treatment technologies also considered existing permits, current the NNSS Disposal Facility infrastructure such as utilities and procedures, and past experiences such as green-light and red-light lessons learned. A schedule duration estimate has been developed for permitting, design, and construction of onsite treatment capability at the NNSS Disposal Facility. Treatment capability can be ready in 20 months.

    Energy availability in a country is of great importance to its economy and to raising and maintaining its standard of living. In 1994, the United States consumed more than 88 quadrillion Btu (quads) of energy and spent about $500 billion on fuels and electricity. Fortunately, the United States is well endowed with energy sources, notably fossil fuels, and possesses a considerable nuclear power industry. The United States also has significant renewable energy resources and already exploits much of its hydropower resources, which represent 10% of electricity production. Nevertheless, in 1994, the United States imported about 45% of the petroleum products it consumed, equivalent to about 17 quads of energy. This dependence on imported oil puts the country at risk of energy supply disruptions and oil price shocks. Previous oil shocks may have cost the country as much as $4 billion (in 1993 dollars) between 1973 and 1990. Moreover, the production and use of energy from fossil fuels are major sources of environmental damage. The corresponding situation in many parts of the world is more challenging. Developing countries are experiencing rapid growth in population, energy demand, and the environmental degradation that often results from industrial development. The near-term depletion of energy resources in response to this rapid growth runs counter to the concept of ''sustainable development''--development that meets the needs of today without compromising the ability of future generations to meet their own needs. Energy research and development (R&D) to improve efficiency and to develop and deploy energy alternatives may be viewed, therefore, as an insurance policy to combat the dangers of oil shocks and environmental pollution and as a means of supporting sustainable development. These considerations guide the energy policy of the United States and of the U.S. Department of Energy (DOE). In its strategic plan, DOE identifies the fostering of &apos

    1993-01-29

    The PHENIX Conceptual Design Report (CDR) describes the detector design of the PHENIX experiment for Day-1 operation at the Relativistic Heavy Ion Collider (RHIC). The CDR presents the physics capabilities, technical details, cost estimate, construction schedule, funding profile, management structure, and possible upgrade paths of the PHENIX experiment. The primary goals of the PHENIX experiment are to detect the quark-gluon plasma (QGP) and to measure its properties. Many of the potential signatures for the QGP are measured as a function of a well-defined common variable to see if any or all of these signatures show a simultaneous anomaly due to the formation of the QGP. In addition, basic quantum chromodynamics phenomena, collision dynamics, and thermodynamic features of the initial states of the collision are studied. To achieve these goals, the PHENIX experiment measures lepton pairs (dielectrons and dimuons) to study various properties of vector mesons, such as the mass, the width, and the degree of yield suppression due to the formation of the QGP. The effect of thermal radiation on the continuum is studied in different regions of rapidity and mass. The e{mu} coincidence is measured to study charm production, and aids in understanding the shape of the continuum dilepton spectrum. Photons are measured to study direct emission of single photons and to study {pi}{sup 0} and {eta} production. Charged hadrons are identified to study the spectrum shape, production of antinuclei, the {phi} meson (via K{sup +}K{sup {minus}} decay), jets, and two-boson correlations. The measurements are made down to small cross sections to allow the study of high p{sub T} spectra, and J/{psi} and {Upsilon} production. The PHENIX collaboration consists of over 300 scientists, engineers, and graduate students from 43 institutions in 10 countries. This large international collaboration is supported by US resources and significant foreign resources.

  16. Restructured site characterization program at Yucca Mountain

    International Nuclear Information System (INIS)

    During 1994 and the early part of 1995, the US Department of Energy's Yucca Mountain Site Characterization Office (YMSCO) and its parent organization, the Office of Civilian Radioactive Waste Management (OCRWM) underwent a significant restructuring. Senior Department officials provided the leadership to reorient the management, technical, programmatic, and public interaction approach to the US High Level Radioactive Waste Disposal Program. The restructuring involved reorganizing the federal staff, conducting meaningful strategic planning, improving the management system, rationalizing contractor responsibilities, focusing upon major products, and increasing stakeholder involvement. The restructured program has prioritized technical and scientific activities toward meeting major regulatory milestones in a timely and cost-effective manner. This approach has raised concern among elements of technical, scientific, and oversight bodies that suitability and licensing decisions could be made without obtaining sufficient technical information for this first-of-its-kind endeavor. Other organizations, such as congressional committees, industrial groups, and rate payers believe characterization goals can be met in a timely manner and within the limitation of available funds. To balance these contrasting views in its decision making process, OCRWM management has made a special effort to communicate its strategy to oversight bodies, the scientific community and other stakeholders and to use external independent peer review as a key means of demonstrating scientific credibility. Site characterization of Yucca Mountain in Nevada is one of the key elements of the restructured program

    The conceptual design of the high luminosity electron-ion collider, eRHIC, is presented. The goal of eRHIC is to provide collisions of electrons (and possibly positrons) with ions and protons at the center-of-mass energy range from 25 to 140 GeV, and with luminosities exceeding 10{sup 33} cm{sup -2} s{sup -1}. A considerable part of the physics program is based on polarized electrons, protons and He3 ions with high degree of polarization. In eRHIC electron beam will be accelerated in an energy recovery linac. Major R&D items for eRHIC include the development of a high intensity polarized electron source, studies of various aspects of energy recovery technology for high power beams and the development of compact magnets for recirculating passes. In eRHIC scheme the beam-beam interaction has several specific features, which have to be thoroughly studied. In order to maximize the collider luminosity, several upgrades of the existing RHIC accelerator are required. Those upgrades may include the increase of intensity as well as transverse and longitudinal cooling of ion and proton beams.

    Full Text Available This paper will track my battle to ‘get conceptual’ in the production of a Grounded Theory. It will discuss early attempts at creating substantive codes through the process of open coding which, despite my best efforts, merely produced descriptive codes. It will illustrate the process by which these descriptive codes became more conceptual, earning the title of substantive code and how their presentation in essay form produced a perfect example of ‘conceptual description’. It will then describe the slow dawning of the purpose of ‘theoretical codes’ as organisers of substantive codes and the emergence of a Grounded Theory.

    Full Text Available Introduction: It presents the development of a proposed conceptual model for digital educational games in the context of the classroom in which the analysis focused on learning for sustainable habits production and consumption in the residential environment. The existing conceptual models are more linked to the creation and recently with evaluation of the games. In the context of the implementation, most models focus more on the description of the games validation processes than in mediating the pedagogical practice itself. Therefore, the research question is about how to create, implement and evaluate digital educational games for teaching and learning process in the classroom, with the focus on learning the culture of sustainability in the residential environment. Methodology: As far as the methodological characterization is concerned, the investigation was supported by bibliographical and field research for data collection. It was emphasized the use of Design Science Research Methodology as methodological procedure for the development of the conceptual model. Results: The system has been tested in a pilot study in two groups of Young Apprentice Program at SENAC/SC to check its consistency. Conclusions: It was concluded based on the results produced by the application of the pilot that the proposed conceptual model contributes to the process of teaching and learning in the classroom.

    1997-01-01

    The University of Texas at El Paso (UTEP) established the Pan American Center for Earth and Environmental Studies (PACES) in 1995 to conduct basic and applied research that contributes to NASA's Mission to Planet Earth. Specifically, PACES provides a repository of remote sensing and other information that supports investigations into an improved understanding of geological, ecological and environmental processes occurring in the southwestern United States and Northern Mexico. Approximately 85% of UTEP's students come from El Paso County, a fast growing urban region representative of many large cities in the Southwest that have, or will soon have, a majority of their population composed of groups currently underrepresented in the scientific and technical workforce. UTEP's student population has an ethnic distribution (63% Hispanic, 32% Anglo, 3% African American, 1.5 % Asian American, and less than 1% Native American) that closely matches the demographics of the region it serves. Thus, UTEP has a mission to serve a multicultural population where minority students comprise the majority. Most Hispanic students at UTEP are primarily of Mexican origin. A large number are first or second-generation U.S. citizens. Characteristics that unite Hispanic students, in particular those of Mexican-origin, are a strong sense of family loyalty and a belief that all family members are responsible for contributing to the economic stability and well-being of the family. Most of their families are larger in number than the national average, and a variety of generations live together or share considerable resources. Thus, many young people feel an obligation and a desire to go to work at a young age and to continue working while in college, thereby assisting their parents and other family members. Older siblings understand that they have responsibilities to do household chores, to aid their younger siblings economically, and to assist elderly family members. This "work ethic" within the

    Full Text Available Abstract. Nowadays, an integrated location, descriptive inventory data and geographical information are required for a better decision making in Indigenous community management activities. The management system can improve productivity and to save time, money and man power. Conventional maps and Indigenous inventories on papers or spread sheet are lack of meeting these requirements which are not static and subjected to change rapidly. The Geographic Information Systems (GIS and Database Management (DBM System are capabilities and confined in manipulation of location and descriptive data, respectively. A GIS system is chosen in Management Information and Infrastructure of Indigenous Communities because its meets all the requirements that can help the authorities to managed the community. GIS able to manipulate location and descriptive data as well as the relationships between them are dynamic. This paper will discussed briefly the conceptual design of GIS activities and Indigenous community in Royal Belum State Park, Malaysia, then terminology and theoretical concepts of GIS, Indigenous community management and the link between them are reviewed.Keywords:  Management, information, infrastructure, conceptual design, Indigenous community 

  16. Implementing a risk management program at Falconbridge

    International Nuclear Information System (INIS)

    A corporate overview of Falconbridge was presented. Falconbridge, founded in 1928 is a leading producer of nickel, copper, cobalt and platinum group metals at low cost. A map displaying its worldwide locations was shown. In Canada, Falconbridge operates in Ontario and Nunavik Territory. The experience in Norway was briefly described, touching on market volatility, market intelligence, portfolio management, and risk management guidelines. The author then explained the purpose of the Energy Project Team, which was responsible for preparing for deregulation, developing strategies for purchasing energy, and minimizing the cost of purchased energy in a competitive market. The plan was described, and the emphasis placed on the core Ontario team. Communication played a large part. The management system functions were reviewed, and analysis provided. The financial integration model was presented. Risk management was dealt with, followed by market intelligence and operational hedge. Division impact was discussed. The major Falconbridge issues were: budget exposure to electricity price variability, how much fixed-price power supply and how long should the contracts be, regulatory structure, market purchase timing, and adhere to corporate risk management policy. The procurement process was described. The author concluded that the product must be kept simple and the number of products limited. A realistic schedule must by adhered to, and a short bidding period of four hours proved ideal. Supplier relationship must be consumer driven. The importance of communication plan was emphasized. Getting pre-approval to make the deal is important. tabs., figs

    In this manuscript we bring to focus student perceptions of salience (or lack of thereof) of emotions in the undergraduate conceptual physics course (in the teacher education program) and their relevance to teaching and learning. Our analysis of student responses to the Mindfulness in Education Heuristic constitutes a feedback loop affording the teacher reflection over his instructional practices. Hence, we ponder pedagogical tools employed by the class instructor (second author) that students identify as evoking emotional responses (both positive and negative). Furthermore, we highlight this teacher's dispositions and his value system (axiology) that appear to bring to balance his passion for science (understood in a traditional Western way as a canon-based epistemology) and his approach to teaching that is driven by compassion towards his students many of whom perceive physics as challenging. We argue that adopting mindful disposition affords engaging in practices that assist in regulating emotions and attention that mediate learning of canonical science content. Likewise, we maintain that the instructor and his mindfulness-driven practices become a model to be replicated in his students' future careers. In such context, mindfulness may be perceived as part of what is referred to as a hidden curriculum. It is our position, however, that the science classroom is a site where wellness-promoting practices (such as mindfulness) should receive an overt attention by becoming science content to be learned and practiced by all citizens throughout everyday life thus contributing to its improved quality. In recognizing that such position may be challenging to adopt by science educators, we present the way the second author has been grappling with reframing his thinking around teaching science. We encourage educators to utilize heuristic methodology towards reflecting on and informing their practice and as one way of exposing their students to social constructs such as

  20. Second annual report of the Environmental Restoration Monitoring and Assessment Program at Oak Ridge National Laboratory

    International Nuclear Information System (INIS)

    This report summarizes the salient features of the annual efforts of environmental monitoring and field investigations conducted to support the Environmental Restoration (ER) Program at the Oak Ridge National Laboratory (ORNL). This report focuses on the watershed scale, striving to provide an ORNL site-wide perspective on types, distribution, and transport of contamination. Results are used to enhance the conceptual understanding of the key contaminants and the sources, fluxes, and processes affecting their distribution and movement. This report summarizes the efforts of the Waste Area Grouping (WAG) 2 and Site Investigations (SI) program. WAG 2 is the lower portion of the White Oak Creek (WOC) system which drains the major contaminated sites at ORNL and discharges to the Clinch River where public access is allowed. The remedial investigation for WAG 2 includes a long-term multimedia environmental monitoring effort that takes advantage of WAG 2's role as an integrator and conduit of contaminants from the ORNL site. This report also includes information from other site-specific remedial investigations and feasibility studies (RI/FS) for contaminated sites at ORNL and data from other ongoing monitoring programs conducted by other organizations [e.g., the National Pollutant Discharge Elimination System (NPDES) compliance monitoring conducted by the Environmental Surveillance and Protection Section]. This information is included to provide an integrated basis to support ER decision making. This report summarizes information gathered through early 1993. Annual data, such as annual discharges of contaminants, are reported for calendar year 1992

  2. Cross software for microprocessor program development at CERN

    International Nuclear Information System (INIS)

    Programs for a variety of microprocessors (including Intel 8080; Motorola 6800 and 6809 and 68000; and Texas Instruments 9900) can be prepared on different host computers (such as IBM 370, CDC 6000, and Nord 10) using portable programs developed at CERN. The range of cross software consists of: an assembler for each target microprocessor, a single linkage editor, a single object module librarian, and a variety of pre-loaders which convert object modules from CERN's format (CUFOM) into manufacturers' formats. The programs are written in BCPL and PASCAL, programming languages which are available on a wide range of computers. (orig.)

  6. Organizational closure and conceptual coherence

    2000-01-01

    This paper reviews ideas developed by the late Gordon Pask as part of this conversation theory (CT). CT uses theories of the dynamics of complex, self-organizing systems, in conjunction with models of conceptual structures, in order to give an account of conceptual coherence (for example, of a theory or a belief system) as a form of organizational closure. In Pask's own terms, CT is concerned both with the kinematics of knowledge structures and the kinetics of knowing and coming to know. The main features of modelling conceptual structures and processes used by Pask are presented. We continue by presenting a summary two-cycle model of learning, aimed to capture some of Pask's key insights with respect to conceptual coherence and the organizational closure of conceptual systems. Parallels are drawn with other work in epistemology, classic cybernetic studies of self-organization, and the concept of autopoiesis. The two-cycle model is then applied recursively to generate learning cycles and conceptual structures at different levels of abstraction, as a contribution to the work of Pask on the topology of thought. Finally, the model is applied reflexively. That is, its own form is considered as a topic for conversation and conceptualization. Carrying out such a reflection provides a coherent way of characterizing epistemological limits, while retaining a clear sense of there being an (in principle) unlimited praxeology of awareness.

  7. How Prospective Teachers Conceptualized Mathematics: Implications for Teaching

    Directory of Open Access Journals (Sweden)

    2015-08-01

    Full Text Available What is mathematics? The difficulty of having a precise, universal definition of mathematics has led prospective teachers to define the term in ways that make sense to them. This paper is part of a larger research project conducted in 2000 in an Ontarian university, Canada. The objectives were to identify and discuss conceptualizations of mathematics that prospective teachers brought to their preparation program and to explore the implications of such conceptualizations in terms of teaching and learning. It was believed that both the identification tools and understandings of prospective teachers’ conceptualizations of mathematics were significant for designing an effective pedagogy in accordance with mathematics reform-based perspectives. The research sample consisted of ten prospective teachers enrolled in a one-year bachelor of education program at an Ontarian university. The research used mathematics autobiographies of the respondents and semi-structured interviews of them as sources of data. Guided by the theory of personal construct for analysis of the data, the results showed that the respondents conceptualized mathematics in terms of metaphor, metonymy and combination of the two. The conclusion explores implications of such conceptualizations for mathematics teaching, learning and assessment.

  9. Successful Minority PhD Producing Programs -- Bell Laboratories and the Meyerhoff Scholarship Program at UMBC

    Science.gov (United States)

    Johnson, Anthony

    2009-03-01

    The Bell Labs Cooperative Research Fellowship Program for Minorities (CRFP), founded in 1972 was one of the first programs of its kind in the US to address the issue of under-representation of minorities in the fields of engineering, mathematics and science. As of 2000, well over 100 PhDs graduated with CRFP sponsorship and a significant fraction joined the research ranks of Bell Labs. In the early days of the program as much as 50% of African American PhDs in Physics in the US were granted to students supported by CRFP. Another unique program initiated by Bell Labs in 1974 that introduced undergraduate students to cutting edge research was the Summer Research Program for Minorities and Women (SRP). The SRP served as a natural feeder to the CRFP. Personally, my career in Optical Physics owes its foundation to these programs and I will give my perspective on participation and impact of the Bell Labs SRP (1974) and CRFP (1975) programs. The Meyerhoff Scholars Program at UMBC was developed in 1988. At that time, UMBC was graduating fewer than 18 African-American STEM majors per year. In 1996 the program was opened to all students with an interest in the advancement of minorities in STEM fields. The program enjoys an overall 18-year retention rate of greater than 95% and has over 500 graduates since 1993. As of May 2006, 75% of these graduates are enrolled in graduate and/or professional programs, with 49 PhDs and 20 MD/PhDs completed as of August 2006. The program challenges notions about minority achievement. Meyerhoff Scholars have changed the perceptions of those around them -- the expectations of faculty who instruct them, the attitudes of students who learn beside them, and the perspectives of scientists who engage them in research.

  10. Relativism: A conceptual analysis.

    Directory of Open Access Journals (Sweden)

    Vittorio Villa

    2010-01-01

    Full Text Available In this paper, first, I will try to give a conceptual definition of relativism, with the aim of singling out the basic elements common to the most relevant relativist conceptions. I will qualify as “relativistic” all conceptions in which all or a relevant part of its criteria and beliefs necessarily depend on a given context. Secondly, I will deal with some critical observations against relativism. From this point of view, a problem arises from the fact that many relativists would like to have the chance ofexpressing some objective judgments. Lastly, I will propose a relativistic conception: one that doesn’t incorporate absolutist elements at all and nevertheless could be able to explain the presence of a common core of criteria and beliefs in all our conceptual schemes and beliefs. Two distinctions are important here: first, local conceptual schemes and long term frameworks, and second, environment and world. This last distinction makes possible to speak, even inside a coherent relativist epistemological conception, of the existence of an objective reality.

  12. Integrated environmental monitoring program at the Hanford Site

    International Nuclear Information System (INIS)

    The US Department of Energy's Hanford Site, north of Richland, Washington, has a mission of defense production, waste management, environmental restoration, advanced reactor design, and research development. Environmental programs at Hanford are conducted by Pacific Northwest Laboratory (PNL) and the Westinghouse Hanford Company (WHC). The WHC environmental programs include the compliance and surveillance activities associated with site operations and waste management. The PNL environmental programs address the site-wide and the of-site areas. They include the environmental surveillance and the associated support activities, such as dose calculations, and also the monitoring of environmental conditions to comply with federal and state environmental regulations on wildlife and cultural resources. These are called ''independent environmental programs'' in that they are conducted completely separate from site operations. The Environmental Surveillance and Oversight Program consists of the following projects: surface environmental surveillance; ground-water surveillance; wildlife resources monitoring; cultural resources; dose overview; radiation standards and calibrations; meteorological and climatological services; emergency preparedness

    Full Text Available This study investigated the service Physical Education Program at Batangas State University system based on the assessments of the administrators, faculty and students on its implementation in consideration of its program components and attitudes of PE teachers towards the subject with the proposed revitalized Physical Education program as an output. Using descriptive research design of research and statistical tools such as percentage, weighted mean, and f-test, the result showed a great extent of the implementation of the service Physical Education program at BSU system in terms of attainment of objectives, curriculum, teaching effectiveness of faculty, and adequacy of facilities, equipment, supplies, and instructional materials. Positive attitudes towards PE except on the concerns on reducing the time allocation for the subject and that it should be mainly sports and play were among the findings. In addition, the objectives of the PE program are believed to be the best indicators while the least indicator is the facilities, equipment and supplies.

  14. Brief communication: Reaction to fire by savanna chimpanzees (Pan troglodytes verus) at Fongoli, Senegal: Conceptualization of "fire behavior" and the case for a chimpanzee model.

    Science.gov (United States)

    Pruetz, Jill D; LaDuke, Thomas C

    2010-04-01

    The use and control of fire are uniquely human traits thought to have come about fairly late in the evolution of our lineage, and they are hypothesized to correlate with an increase in intellectual complexity. Given the relatively sophisticated cognitive abilities yet small brain size of living apes compared to humans and even early hominins, observations of wild chimpanzees' reactions to naturally occurring fire can help inform hypotheses about the likely responses of early hominins to fire. We use data on the behavior of savanna chimpanzees (Pan troglodytes verus) at Fongoli, Senegal during two encounters with wildfires to illuminate the similarities between great apes and humans regarding their reaction to fire. Chimpanzees' close relatedness to our lineage makes them phylogenetically relevant to the study of hominid evolution, and the open, hot and dry environment at Fongoli, similar to the savanna mosaic thought to characterize much of hominid evolution, makes these apes ecologically important as a living primate model as well. Chimpanzees at Fongoli calmly monitor wildfires and change their behavior in anticipation of the fire's movement. The ability to conceptualize the "behavior" of fire may be a synapomorphic trait characterizing the human-chimpanzee clade. If the cognitive underpinnings of fire conceptualization are a primitive hominid trait, hypotheses concerning the origins of the control and use of fire may need revision. We argue that our findings exemplify the importance of using living chimpanzees as models for better understanding human evolution despite recently published suggestions to the contrary.

    2011-12-01

    With funding from an NSF Informal Science Education grant, the Pacific Science Center in Seattle, Washington began the Science Communication Fellowship program in 2009 as part of the Portal to the Public initiative. The purpose of the Science Communication Fellowship program is to train scientists and engineers to communicate more effectively with the general public regarding their research and to assist with the development of hands-on activities that can be used by the scientists and engineers for outreach activities. The program came out of a collaboration to develop a model for effectively communicating current science research at informal science education organizations. The program model has undergone in-depth research and evaluation to assess its effectiveness and impact. To become Science Communication Fellows, researchers participate in four three-hour professional development sessions, where they learn communication techniques through role-playing and hands-on activities. The workshops are supplemented with additional one-on-one meetings with Science Center staff to help the new Fellows develop activities for use at outreach events. These activities are then used by the Fellows at public events that highlight current research taking place in the region. To date over 80 scientists and engineers have gone through the training sessions to become Science Communication Fellows. The Pacific Science Center holds approximately 12 events a year in which Fellows can facilitate their activity. Public programs range from small, monthly programs to large, annual Research Weekends. Funding for this program continues through support from NIH, IMLS, NSF, and NASA grants.

  1. INEEL Subregional Conceptual Model Report Volume 2: Summary of Existing Knowledge of Geochemical Influences on the Fate and Transport of Contaminants in the Subsurface at the INEEL

    Energy Technology Data Exchange (ETDEWEB)

    Paul L. Wichlacz; Robert C. Starr; Brennon Orr

    2003-09-01

    This document summarizes previous descriptions of geochemical system conceptual models for the vadose zone and groundwater zone (aquifer) beneath the Idaho National Engineering and Environmental Laboratory (INEEL). The primary focus is on groundwater because contaminants derived from wastes disposed at INEEL are present in groundwater, groundwater provides a pathway for potential migration to receptors, and because geochemical characteristics in and processes in the aquifer can substantially affect the movement, attenuation, and toxicity of contaminants. The secondary emphasis is perched water bodies in the vadose zone. Perched water eventually reaches the regional groundwater system, and thus processes that affect contaminants in the perched water bodies are important relative to the migration of contaminants into groundwater. Similarly, processes that affect solutes during transport from nearsurface disposal facilities downward through the vadose zone to the aquifer are relevant. Sediments in the vadose zone can affect both water and solute transport by restricting the downward migration of water sufficiently that a perched water body forms, and by retarding solute migration via ion exchange. Geochemical conceptual models have been prepared by a variety of researchers for different purposes. They have been published in documents prepared by INEEL contractors, the United States Geological Survey (USGS), academic researchers, and others. The documents themselves are INEEL and USGS reports, and articles in technical journals. The documents reviewed were selected from citation lists generated by searching the INEEL Technical Library, the INEEL Environmental Restoration Optical Imaging System, and the ISI Web of Science databases. The citation lists were generated using the keywords ground water, groundwater, chemistry, geochemistry, contaminant, INEL, INEEL, and Idaho. In addition, a list of USGS documents that pertain to the INEEL was obtained and manually searched

  3. Global products or customization to different countries: Conceptual framework and application at Wahler, A german company Of the automotive sector

    Directory of Open Access Journals (Sweden)

    Ailton Conde Jussani

    2013-12-01

    Full Text Available Competition in global markets demands product strategies that can help firms deal with the dilemma of global products versus customization, in serving the markets of different countries. Global products lead to large scales, automation, lower costs, plus the easy transfer of people and technology among many subsidiaries, as well as between corporate headquarters and the subsidiaries. However, the lack of customization makes it difficult to gain share in countless market segments, in many countries, and it may even stop a firm from entering in certain countries. This study outlines a model designed to facilitate this type of decision-making. First, based on the literature, a conceptual model was drawn up and the decision-related elements were grouped into seven factors that aid product customization decisions: 1. Market Positioning; 2. Customers’ strategic importance; 3. Product life-cycle development; 4. Legal requirements; 5. Physical environment; 6. Infrastructure and compatibility; and 7. Suppliers’ strategic importance. The case method was used, given the complex nature of the problem, which calls for an in-depth analysis. The model was tested on one of the products made a German company with a Brazilian subsidiary. The components of the valve and the technological trends were analyzed. The case study showed that the influencing factors are interrelated. It became clear that the technological component is directly related with the seven decision factors, and this aspect is analyzed in depth. Nevertheless, further studies are necessary to validate the model, since the case method does not allow one to generalize the findings.

    A new Radiochemistry Education and Research Program was started at the Pennsylvania University, Radiation Science and Engineering Center. The program was initially supported by the Department of Energy, Radiochemistry Education Award Program (REAP). Using REAP funding as leverage we obtained support from the Los Alamos National Laboratory, Department of Homeland Security, Domestic Nuclear Detection Office, various internal funding from PSU and other entities. The PSU radiochemistry program primarily addresses radiochemistry education and secondarily nuclear and radiochemistry research. The education program consists of bolstering our existing radiochemistry and related courses; Nuclear and Radiochemistry, Radiation Detection and Measurement, Radiological Safety and developing new courses, e.g., Laboratory Experiments in Applied Nuclear and Radiochemistry, and Nuclear Methods in Science. A new laboratory has been created with state of the art equipment for the Laboratory Experiments in Applied Nuclear and Radiochemistry course. We also plan to revitalize the nuclear and radiochemistry research programs. We established a state-of-the-art Neutron Activation Analysis Laboratory and a gamma ray spectroscopy laboratory that has 10 stations including state-of-the-art nuclear spectroscopy hardware and software. In addition, we embarked on an expansion plan that included building a new neutron beam hall and neutron beam ports with a cold neutron source. One of the reasons to have a cold neutron source is for the development of a prompt gamma activation analysis facility. A detailed description of PSU radiochemistry education and research program will be given and the future plans will be discussed.

    NONE

    1994-12-01

    This report presents results of Task 3 of the Westinghouse ATS Phase II program. Objective of Task 3 was to analyze and evaluate different cycles for the natural gas-fired Advanced Turbine Systems in order to select one that would achieve all ATS program goals. About 50 cycles (5 main types) were evaluated on basis of plant efficiency, emissions, cost of electricity, reliability-availability-maintainability (RAM), and program schedule requirements. The advanced combined cycle was selected for the ATS plant; it will incorporate an advanced gas turbine engine as well as improvements in the bottoming cycle and generator. Cost and RAM analyses were carried out on 6 selected cycle configurations and compared to the baseline plant. Issues critical to the Advanced Combined Cycle are discussed; achievement of plant efficiency and cost of electricity goals will require higher firing temperatures and minimized cooling of hot end components, necessitating new aloys/materials/coatings. Studies will be required in combustion, aerodynamic design, cooling design, leakage control, etc.

    2001-09-30

    The objective of the ATS program is to develop ultra-high efficiency, environmentally superior and cost competitive gas turbine systems for base load application in utility, independent power producer and industrial markets. Specific performance targets have been set using natural gas as the primary fuel: (1) System efficiency that will exceed 60% (lower heating value basis) on natural gas for large scale utility turbine systems; for industrial applications, systems that will result in a 15% improvement in heat rate compared to currently available gas turbine systems. (2) An environmentally superior system that will not require the use of post combustion emissions controls under full load operating conditions. (3) Busbar energy costs that are 10% less than current state-of-the-art turbine systems, while meeting the same environmental requirements. (4) Fuel-flexible designs that will operate on natural gas but are capable of being adapted to operate on coal-derived or biomass fuels. (5) Reliability-Availability-Maintainability (RAM) that is equivalent to the current turbine systems. (6) Water consumption minimized to levels consistent with cost and efficiency goals. (7) Commercial systems that will enter the market in the year 2000. In Phase I of the ATS program, Siemens Westinghouse found that efficiency significantly increases when the traditional combined-cycle power plant is reconfigured with closed-loop steam cooling of the hot gas path. Phase II activities involved the development of a 318MW natural gas fired turbine conceptual design with the flexibility to burn coal-derived and biomass fuels. Phases I and II of the ATS program have been completed. Phase III, the current phase, completes the research and development activities and develops hardware specifications from the Phase II conceptual design. This report summarizes Phase III Extension activities for a three month period. Additional details may be found in monthly technical progress reports covering the

    Hughes, Chris

    2008-03-01

    Over the past decade a core group of faculty at James Madison University has created an interdisciplinary program in materials science that provides our students with unique courses and research experiences that augment the existing, high-quality majors in physics and astronomy, chemistry and biochemistry, geology and environmental science, mathematics and statistics, and integrated science and technology. The university started this program by creating a Center for Materials Science whose budget is directly allocated by the provost. This source of funds acts as seed money for research, support for students, and a motivating factor for each of the academic units to support the participation of their faculty in the program. Courses were created at the introductory and intermediate level that are cross-listed by the departments to encourage students to enroll in them as electives toward their majors. Furthermore, the students are encouraged to participate in undergraduate research in materials since this is the most fundamental unifying theme across the disciplines. This talk will cover some of the curricular innovations that went into the design of the program to make it successful, examples of faculty and student research and how that feeds back into the classroom, and success stories of the interactions that have developed between departments because of this program. Student outcomes and future plans to improve the program will also be discussed.

  12. The duty health physicist program at Byron Nuclear Power Station

    International Nuclear Information System (INIS)

    The Duty Health Physicist Program at Byron Station was established to deal with routine health physics tasks and provide an interface between frontline and upper radiation-chemistry management. The program consists of a weekly rotation of selected members of the health physics staff into the duty health physicist position to handle the assigned duty tasks. The tasks include, but are not limited to, daily isotopic and air sample review, effluent release package review, maximum permissible concentration calculations, dose approvals, as-low-as-reasonably-achievable action review of pending jobs, and general availability to answer questions and address problems in health-physics-related areas of plant operation. The daily attendance of the duty health physicist at the radiation-chemistry and station plan-of-the-day meetings has increased the overall presence and visibility of the health physics program to upper station management and other station departments. Since its inception in July of 1985, the Duty Health Physics Program has been a major contributor to the observed 50% reduction in reportable personnel errors in the radiation-chemistry department (based on personnel-error-related deviation reports and license event reports generated on the radiation-chemistry department at Byron Station). Although difficulty to quantify, other important benefits of this program are also discussed in this paper

    1995-10-01

    In response to the industrial and utility objectives specified for the ATS, the GE Power Generation ATS Phase 2 Program consisted of a dual approach. These were (1) development of an Industrial ATS (aircraft engine based) led by GE Aircraft Engines, and (2) development of a Utility ATS which was already underway at GEPG. Both programs required the identification and resolution of critical technical issues. Both systems were studied in Tasks 3-7, and both have resulted in designs that meet all ATS goals. The Industrial ATS as defined (130 MW) did not meet projected market power size requirements, and emphasis has remained on the Utility ATS development. The design and testing effort has been focused on the MS7001H combined cycle gas turbine, as the next product evolution in GE Power Generation`s product line.

    This conceptual design report documents the redesign of the IPSS and the OIP in the 105 KW Basin south loadout pit due to a postulated cask drop accident, as part of Project A.5/A.6, Canister Transfer Facility Modifications. Project A.5/A.6 involves facility modifications needed to transfer fuel from the basin into the cask-MCO. The function of the IPSS is to suspend, guide, and position the immersion pail. The immersion pail protects the cask-MCO from contamination by basin water and acts as a lifting device for the cask-MCO. The OIP provides operator access to the south loadout pit. Previous analyses studied the effects of a cask-MCO drop on the south loadout pit concrete structure and on the IPSS. The most recent analysis considered the resulting loads at the pit slab/wall joint (Kanjilal, 1999). This area had not been modeled previously, and the analysis results indicate that the demand capacity exceeds the allowable at the slab/wall joint. The energy induced on the south loadout pit must be limited such that the safety class function of the basin is maintained. The solution presented in this CDR redesigns the IPSS and the OIP to include impact-absorbing features that will reduce the induced energy. The impact absorbing features of the new design include: Impact-absorbing material at the IPSS base and at the upper portion of the IPSS legs. A sleeve which provides a hydraulic means of absorbing energy. Designing the OIP to act as an impact absorber. The existing IPSS structure in 105 KW will be removed. This conceptual design considers only loads resulting from drops directly over the IPSS and south loadout pit area. Drops in other areas of the basin are not considered, and will be covered as part of a future revision to this CDR.

    The magnet program at Brookhaven National Laboratory (BNL) is focussed on superconducting magnets for particle accelerators. The effort includes magnet production at the laboratory and in industry, magnet R&D, and test facilities for magnets and superconductors. Nearly 2000 magnets-dipoles, quadrupoles, sextupoles and correctors for the arc and insertion regions-were produced for the Relativistic Heavy Ion Collider (RHIC), which is being commissioned. Currently, production of helical dipoles for the polarized proton program at RHIC, insertion region dipoles for the Large Hadron Collider (LHC) at CERN, and an insertion magnet system for the Hadron-Elektron-Ring- Analage (HERA) collider at Deutsches Elektronen-Synchrotron (DESY) is underway. The R&D effort is exploring dipoles with fields above 10 T for use in post-LHC colliders. Brittle superconductors-Nb/sub 3/Sn or HTS-are being used for these magnets. The superconductor test facility measures short-sample currents and other characteristics of sample...

    The `conceptual storyline' of a lesson refers to the flow and sequencing of learning activities such that science concepts align and progress in ways that are instructionally meaningful to student learning of the concepts. Research demonstrates that when teachers apply lesson design strategies to create a coherent science content storyline, student learning is positively impacted (Roth et al., 2011). Because the conceptual storyline is often implicit within a lesson, and teachers often have difficulty articulating this aspect of lesson design (Lo et al., 2014), our professional development program engages elementary teachers in analyzing and developing graphic representations of a lesson's conceptual storyline to make that element explicit. In this exploratory study, we present typologies that represent two primary challenges teachers faced in developing coherent conceptual storylines in their lesson design, and examine the extent to which professional development enhanced their capacity to develop a coherent conceptual storyline.

    Fermilab, in collaboration with LBNL and BNL, is developing a quadrupole for installation in the interaction region inner triplets of the LHC. This magnet is required to have an operating gradient of 215 T/m across a 70 mm coil bore, and operates in superfluid helium at 1.9 K. A 2 m magnet program addressing mechanical, magnetic, quench protection, and thermal issues associated with the design was completed earlier this year, and production of the first full length, cryostatted prototype magnet is underway. This paper summarizes the conclusions of the 2 m program, and the design and status of the first full-length prototype magnet. (11 refs).

  3. USING LOGIC COMPONENTS FOR CONCEPTUAL DIE DESIGN

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    Logic components are used to support the conceptual design. Taking the stamping die structure as the research object,several logic components are defined for the conceptual die construction design. A new method-logic assembly modeling is presented to satisfy the characteristic of the top-down die design process. Representing shapes and spatial relations in logic can provide a natural,intuitive method of developing complete computer systems for reasoning about die construction design at the conceptual stage. This method can reflect the designer's thought clearly and provide the designer with a test bed for generating alternatives and performing reasoning work at the conceptual die design stage.

    1998-09-01

    The Eastern Washington Section of the American Nuclear Society (ANS) has tried a number of different approaches to reach out to the local communities and to work alongside educators to increase their awareness of nuclear technology. Some of the programs that the authors have started may serve as examples for other sections in their outreach activities. The Eastern Washington Section of the ANS has an education committee coordinator who is assigned the task of working with high school and college students to increase the awareness of nuclear energy. The most effective approach that the authors have found to reach out to the area schools is to get directly involved with community activities that already interface with the schools and get to know the science teachers at the local schools. The Hanford project has a student internship program called ``Inquiry into Science``. The program allows students to work at Hanford for Science credits. Another program that the local section sponsors is grants to high schools to promote the awareness of nuclear technology. The local section has also worked alongside local community groups to increase nuclear science education. For years the authors have been active in the local science fair, providing awards to nuclear-related science projects. Other community events that the ANS has been involved in include the US Department of Energy Knowledge Bowl and National Engineers.

    2007-07-30

    This report to the Nuclear Regulatory Commission (NRC) describes the development and application of a methodology to systematically and quantitatively assess predictive uncertainty in groundwater flow and transport modeling that considers the combined impact of hydrogeologic uncertainties associated with the conceptual-mathematical basis of a model, model parameters, and the scenario to which the model is applied. The methodology is based on a n extension of a Maximum Likelihood implementation of Bayesian Model Averaging. Model uncertainty is represented by postulating a discrete set of alternative conceptual models for a site with associated prior model probabilities that reflect a belief about the relative plausibility of each model based on its apparent consistency with available knowledge and data. Posterior model probabilities are computed and parameter uncertainty is estimated by calibrating each model to observed system behavior; prior parameter estimates are optionally included. Scenario uncertainty is represented as a discrete set of alternative future conditions affecting boundary conditions, source/sink terms, or other aspects of the models, with associated prior scenario probabilities. A joint assessment of uncertainty results from combining model predictions computed under each scenario using as weight the posterior model and prior scenario probabilities. The uncertainty methodology was applied to modeling of groundwater flow and uranium transport at the Hanford Site 300 Area. Eight alternative models representing uncertainty in the hydrogeologic and geochemical properties as well as the temporal variability were considered. Two scenarios represent alternative future behavior of the Columbia River adjacent to the site were considered. The scenario alternatives were implemented in the models through the boundary conditions. Results demonstrate the feasibility of applying a comprehensive uncertainty assessment to large-scale, detailed groundwater flow

    Analyses were performed to evaluate the performance of the low enriched uranium (LEU) conceptual design fuel for the conversion of the Transient Reactor Test Facility (TREAT) from its current highly enriched uranium (HEU) fuel. TREAT is an experimental nuclear reactor designed to produce high neutron flux transients for the testing of reactor fuels and other materials. TREAT is currently in non-operational standby, but is being restarted under the U.S. Department of Energy’s Resumption of Transient Testing Program. The conversion of TREAT is being pursued in keeping with the mission of the Department of Energy National Nuclear Security Administration’s Material Management and Minimization (M3) Reactor Conversion Program. The focus of this study was to demonstrate that the converted LEU core is capable of maintaining the performance of the existing HEU core, while continuing to operate safely. Neutronic and thermal hydraulic simulations have been performed to evaluate the performance of the LEU conceptual-design core under both steady-state and transient conditions, for both normal operation and reactivity insertion accident scenarios. In addition, ancillary safety analyses which were performed for previous LEU design concepts have been reviewed and updated as-needed, in order to evaluate if the converted LEU core will function safely with all existing facility systems. Simulations were also performed to evaluate the detailed behavior of the UO2-graphite fuel, to support future fuel manufacturing decisions regarding particle size specifications. The results of these analyses will be used in conjunction with work being performed at Idaho National Laboratory and Los Alamos National Laboratory, in order to develop the Conceptual Design Report project deliverable.

  12. Qualified nuclear engineer certification program at Commonwealth Edison

    International Nuclear Information System (INIS)

    Commonwealth Edison (CECo) has utilized a nuclear engineer training and certification program called the Qualified Nuclear Engineer (QNE) Program for many years to ensure that on-site nuclear engineers are ready to assume critical responsibilities in support of reactor operations and reactivity management. Review of this program is significant now because it effectively implements and exceeds the guidance provided by the Institute of Nuclear Power Operations in ACAD 91-017, open-quotes Guidelines for Training and Qualification of Engineering Support Personnelclose quotes for position-specific training of reactor engineers. The CECo QNE program was initiated for boiling water reactor (BWR) station nuclear engineers after reactivity management events occurred in the early 1970s. In 1974 and 1975, two major fuel-failure events occurred in CECo BWR cores caused, in part, by control rod manipulations inappropriate for the original 7 x 7 fuel, which was very susceptible to pellet-clad interaction. In the 1980s pressurized water reactor (PWR) stations across the nation also had a significant number of reactivity management events. From these events, it was apparent that PWR as well as BWR nuclear engineers needed more specialized training to protect the fuel and a PWR QNE program was implemented at CECo. The major purpose of the QNE program is to provide engineers with the proper training and experience to enable them to make good decisions and recommendations regarding core reactivity and fuel performance. The duties that a QNE can be expected to perform after certification include (a) providing reactivity management guidance to operations personnel during normal and abnormal conditions and (b) reviewing special tests, procedures, and modifications that affect reactivity management

    1994-05-01

    The Lake Afton Public Observatory was founded 14 years ago as a joint project of the city, county, local schools, and Wichita State University to provide educational programs for the public and school children. A staff of 4 professional astronomers presents daytime and evening programs at the Observatory and makes presentations in schools to over 20,000 people per year. Programs are scheduled 6 days a week during the academic year and 3 days a week in the summer. Our public programs deviate significantly from the traditional observatory open house by following a specific theme. Selection and discussion of each object is centered on that theme. For example, a program on The Life Story of a Star would view a diffuse nebula (to discuss star formation), a young star cluster (to discuss one outcome of star formation), a double star (to discuss how the properties of stars are determined), and a planetary nebula (to discuss the death of a star). To complement the observing experiences of our visitors, we have developed a wide range of interactive exhibits to develop the concepts touched on in the viewing programs. We have also developed exhibit lending kits for extended use in school classrooms, educational games, activity manuals for teachers, and short videos to introduce single concepts in the classroom. In the past year we have begun to offer a series of workshops for in-service teachers to expand their knowledge of astronomy and to provide them with additional resources for teaching astronomy. This work is supported in part by NSF EPSCoR grant OSR-9255223.

    2009-08-01

    The National Science Foundation is advancing the design of a Deep Underground Science and Engineering Laboratory (DUSEL) at the former Homestake mine in South Dakota. UC Berkeley and LBNL are leading the design effort for the facility and coordinating the definition and integration of the suite of experiments to be coupled to the facility design in the creation of an MREFC (Major Research Equipment and Facility Construction) proposal. The State of South Dakota has marshaled $120M to prepare the site and begin a modest science program at the 4850 ft level. The first physics experiment is anticipated to begin installation in 2009. The current timetable calls for the MREFC Preliminary Design to be assembled by 2010 to be presented to the National Science Board in 2011. This, in turn, indicates that the earliest DUSEL construction start would be FY2013. The MREFC is estimated (before the inclusion of the long baseline neutrino components) at $500--600M, roughly divided evenly between the experimental program and support for the facility. Construction was estimated at 6--8 years. The DOE and NSF are establishing a Joint Oversight Group (JOG) to coordinate the experimental programs and participation in DUSEL. It is anticipated that the JOG would mirror the similar function for the NSF and DOE participation in the LHC, and that DOE-HEP, DOE-NP, and NSF will all participate in the JOG. In parallel with the NSF efforts, DOE-HEP plans to develop a long baseline neutrino program with neutrino beams created at FNAL and aimed at DUSEL. In the P5 report the focus of the program is to pursue CP violation in the lepton sector. The same detectors can also be used for nucleon decay experiments. DOE has indicated that FNAL would be the ''lead lab'' for the long baseline neutrino program and be charged with designing and implementing the neutrino beamline. BNL is to be charged with designing and implementing the detector. The P5 report also emphasizes the

    Due to its interdisciplinary nature, climate science poses wide-ranging challenges for science and mathematics students seeking careers in this field. There is a compelling need for universities to provide coherent programs in climate science in order to train future climate scientists. With funding from NASA Innovations in Climate Education (NICE), California State University, Northridge (CSUN), is creating the CSUN Climate Science Program. An interdisciplinary team of faculty members is working in collaboration with UCLA, Santa Monica College and NASA/JPL partners to create a new curriculum in climate science. The resulting sequence of climate science courses, or Pathway for studying the Mathematics of Climate Change (PMCC), is integrated into a Bachelor of Science degree program in the Applied Mathematical Sciences offered by the Mathematics Department at CSUN. The PMCC consists of courses offered by the departments of Mathematics, Physics, and Geography and is designed to prepare students for Ph.D. programs in technical fields relevant to global climate change and related careers. The students who choose to follow this program will be guided to enroll in the following sequence of courses for their 12 units of upper division electives: 1) A newly created course junior level course, Math 396CL, in applied mathematics which will introduce students to applications of vector calculus and differential equations to the study of thermodynamics and atmospheric dynamics. 2) An already existing course, Math 483, with new content on mathematical modeling specialized for this program; 3) An improved version of Phys 595CL on the mathematics and physics of climate change with emphasis on Radiative Transfer; 4) A choice of Geog 407 on Remote Sensing or Geog 416 on Climate Change with updated content to train the students in the analysis of satellite data obtained with the NASA Earth Observing System and instruction in the analysis of data obtained within a Geographical

    2015-10-01

    Most dental school faculty members arrive on campus with a wealth of clinical experience but little to no teacher training. For the past two decades, there has been a call for schools to educate their faculty on a wide variety of topics including educational methodology and cutting-edge educational techniques through faculty development programs. Drawing on theories of general program evaluation as well as evaluation specific to educational programming, the aim of this study was to investigate outcomes of the Faculty Development Program at the University of Missouri-Kansas City School of Dentistry between 2007 and 2014. A mixed-methods research design gathered quantitative data via email survey sent to all eligible teaching faculty members; it received an overall response rate of 54% (N=51). Qualitative data came from open-ended survey questions and a focus group with seven volunteer faculty participants. The survey data suggested that the stated outcomes of faculty development were being met for all stakeholder groups with varying degrees of success. Focus group results indicated a need for a more formal new faculty orientation and better communication with all about the specific charge of faculty development within the school. Evaluation of faculty development activities in academic dental institutions is a necessary component of the ongoing improvement of dental education. Suggestions for future evaluations include the idea of collaborating with other dental schools to increase sample sizes, which would increase participants' perception of the level of confidentiality and make statistical analyses more robust.

    NASA research scientists work closely with Science Systems and Applications, Inc. (SSAI) personnel at Goddard Space Flight Center (GSFC) on a large variety of education and public outreach (E/PO) initiatives. This work includes assistance in conceptualizing E/PO plans, then carrying through in the development of materials, publication, cataloging, warehousing, and product distribution. For instance, outreach efforts on the Terra, Aqua, and Aura-still in development-EOS missions, as well as planetary and visualization programs, have been coordinated by SSAI employees. E/PO support includes convening and taking part in sessions at professional meetings and workshops. Also included is the coordination of exhibits at professional meetings such as the AGU, AAAS, AMS and educational meetings such as the National Science Teachers Association. Other E/PO efforts include the development and staffing of booths; arranges for booth space and furnishings; shipping of exhibition materials and products; assembling, stocking, and disassembling of booths. E/PO personnel work with organizations external to NASA such as the Smithsonian museum, Library of Congress, U.S. Geological Survey, and associations or societies such as the AGU, American Chemical Society, and National Science Teachers Association to develop products and programs that enhance NASA mission E/PO efforts or to provide NASA information for use in their programs. At GSFC, E/PO personnel coordinate the efforts of the education and public outreach sub-committees in support of the Space and Earth Sciences Data Analysis (SESDA) contract within the GSFC Earth Sciences Directorate. The committee acts as a forum for improving communication and coordination among related Earth science education projects, and strives to unify the representation of these programs among the science and education communities. To facilitate these goals a Goddard Earth Sciences Directorate Education and Outreach Portal has been developed to provide

    GE has achieved a leadership position in the worldwide gas turbine industry in both industrial/utility markets and in aircraft engines. This design and manufacturing base plus our close contact with the users provides the technology for creation of the next generation advanced power generation systems for both the industrial and utility industries. GE has been active in the definition of advanced turbine systems for several years. These systems will leverage the technology from the latest developments in the entire GE gas turbine product line. These products will be USA based in engineering and manufacturing and are marketed through the GE Industrial and Power Systems. Achieving the advanced turbine system goals of 60% efficiency, 8 ppmvd NOx and 10% electric power cost reduction imposes competing characteristics on the gas turbine system. Two basic technical issues arise from this. The turbine inlet temperature of the gas turbine must increase to achieve both efficiency and cost goals. However, higher temperatures move in the direction of increased NOx emission. Improved coating and materials technologies along with creative combustor design can result in solutions to achieve the ultimate goal.

    NASA has a rich history of scientific research that has been conducted throughout our numerous manned spaceflight programs. This scientific research has included animal test subjects participating in various spaceflight missions, including most recently, Space Shuttle mission STS-131. The Animal Care Program at Johnson Space Center (JSC) in Houston, Texas is multi-faceted and unique in scope compared to other centers within the agency. The animal care program at JSC has evolved from strictly research to include a Longhorn facility and the Houston Zoo's Attwater Prairie Chicken refuge, which is used to help repopulate this endangered species. JSC is home to more than 300 species of animals including home of hundreds of white-tailed deer that roam freely throughout the center which pose unique issues in regards to population control and safety of NASA workers, visitors and tourists. We will give a broad overview of our day to day operations, animal research, community outreach and protection of animals at NASA Johnson Space Center.

    Bilheux, Hassina; Herwig, Ken; Keener, Scott; Davis, Larry

    VENUS (Versatile Neutron Imaging Beam line at the Spallation Neutron Source) will be a world-class neutron-imaging instrument that will uniquely utilize the Spallation Neutron Source (SNS) time-of-flight (TOF) capabilities to measure and characterize objects across several length scales (mm to μm). When completed, VENUS will provide academia, industry and government laboratories with the opportunity to advance scientific research in areas such as energy, materials, additive manufacturing, geosciences, transportation, engineering, plant physiology, biology, etc. It is anticipated that a good portion of the VENUS user community will have a strong engineering/industrial research focus. Installed at Beam line 10 (BL10), VENUS will be a 25-m neutron imaging facility with the capability to fully illuminate (i.e., umbra illumination) a 20 cm x 20 cm detector area. The design allows for a 28 cm x 28 cm field of view when using the penumbra to 80% of the full illumination flux. A sample position at 20 m will be implemented for magnification measurements. The optical components are comprised of a series of selected apertures, T0 and bandwidth choppers, beam scrapers, a fast shutter to limit sample activation, and flight tubes filled with Helium. Techniques such as energy selective, Bragg edge and epithermal imaging will be available at VENUS.

    Implementing a laser safety program at the Woods Hole Oceanographic Institution (WHOI) presents many challenges and opportunities for improving safety performance. Getting all laser users to take ownership of safety and comply with all laser safety requirements are key ingredients of a successful laser safety program. WHOI's laser safety program includes the following elements: registration of high power lasers, hazard analysis of laser facilities, proper design of laser facilities, selection of hazard controls, laser safe operating procedures, laser safety training for all laser users, and routine inspections of laser facilities. Laser owners are required to sign the high power laser registration form and agree to comply with all applicable requirements. All laser users are required to sign the laser safe operating procedure that applies to their facility and follow the requirements. Laser users are included in the development of laser safe operating procedures, design of their facilities, review of hazard analysis calculations for their lasers, and in the selection of hazard controls. Laser safety training for new laser users includes a tour of established laser facilities, review of laser safe operating procedure, and a review of basic laser safety information. By engaging the laser users in all elements of the laser safety program, ownership of laser safety at the user level is more easily established and compliance with safety requirements is significantly improved. New laser owners and users are mentored by experienced laser users and are given an opportunity to observe the implementation of laser safety procedures at established laser facilities before operating their own high power lasers. Increased compliance with safety requirements has been demonstrated with fewer non-compliance items noted during annual laser safety inspections, more participation in initial and annual refresher training, and more requests from higher power laser users for assistance

    Full Text Available CONCEPTUAL DELIMITATIONS OF CONTROLLING Nedelcu Serban Universitatea ,,Babes-Bolyai`` Facultatea de Stiinte Economice si Gestiunea Afacerilor 'Controlling' represents a new concept in the Romanian economic environement, being implemented successfully in very few companies. Unlike the German space where controlling is very well represented both at a practical level and in the academia, in Romania controlling can only be found at a practical level, and the specialized literature is restraint, almost absent. Since the practicians of controlling in Romania only know the toolkit they use and not the theoretical elements as well, what is needed in this case is a conceptual delimitation so that controlling would be better implemented, and improved with various elements of the economic environment. In practice, inside various linguistic areas different problems of communication may occur very often in regards to the use of different concepts that may be missunderstood. Therefore in the Romanian research area it becomes imperative to try and clarify the existing issues and to intensify the reasearch in this field. Studying the evolution of the concept we observe that the need for its implementation is primarily experienced at the practical level of the companies, to be then followed by a debate in the specialized literature. The internationalization and the fierce competition that the Romanian companies are confronting on the ecenomic market represent the decissive factor in adopting the concept of controlling.This article is part of the research conducted for my doctoral thesis, 'Controlling in hetergenous economic envirnoments', under the coordination and supervision of Prof.Dr.Dumitru Matis.

    The study of the transverse momentum dependent parton distributions (TMDs) of the nucleon in semi-inclusive deep-inelastic scattering (SIDIS) has emerged as one of the major physics motivations driving the experimental program using the upgraded 11 GeV electron beam at Jefferson Lab’s Continuous Electron Beam Accelerator Facility (CEBAF). The accelerator construction phase of the CEBAF upgrade is essentially complete and commissioning of the accelerator has begun as of April, 2014. As the new era of CEBAF operations begins, it is appropriate to review the body of published and forthcoming results on TMDs from the 6 GeV era of CEBAF operations, discuss what has been learned, and discuss the key challenges and opportunities for the 11 GeV SIDIS program of CEBAF.

    At Fermilab, 9-cell 1.3 GHz superconducting RF (SRF) cavities are prepared, qualified, and assembled into cryomodules (CMs) for Project X, an International Linear Collider (ILC), or other future projects. The 1.3 GHz SRF cavity program includes targeted R&D on 1-cell 1.3 GHz cavities for cavity performance improvement. Production cavity qualification includes cavity inspection, surface processing, clean assembly, and one or more cryogenic low-power CW qualification tests which typically include performance diagnostics. Qualified cavities are welded into helium vessels and are cryogenically tested with pulsed high-power. Well performing cavities are assembled into cryomodules for pulsed high-power testing in a cryomodule test facility, and possible installation into a beamline. The overall goals of the 1.3 GHz SRF cavity program, supporting facilities, and accomplishments are described.

    BRIKEN is a complex detection system to be installed at the RIB-facility of the RIKEN Nishina Center. It is aimed at the detection of heavy-ion implants, $\\beta$-particles, $\\gamma$-rays and $\\beta$-delayed neutrons. The whole detection setup involves the Advanced Implantation Detection Array (AIDA), two HPGe Clover detectors and a large set of 166 counters of 3He embedded in a high-density polyethylene matrix. This article reports on a novel methodology developed for the conceptual design and optimisation of the 3He-tubes array, aiming at the best possible performance in terms of neutron detection. The algorithm is based on a geometric representation of two selected parameters of merit, namely, average neutron detection efficiency and efficiency flatness, as a function of a reduced number of geometric variables. The response of the detection system itself, for each configuration, is obtained from a systematic MC-simulation implemented realistically in Geant4. This approach has been found to be particularly u...

  19. Conceptual Design of a Beam line for Post-Collision extraction and diagnostics at the multi-TeV Compact Linear Collider

    Ferrari, A; Appleby, R; Salt, M

    2009-01-01

    Strong beam-beam effects at the interaction point of a high-energy e+e- linear collider such as the Compact Linear Collider (CLIC) lead to an emittance growth for the outgoing beams, as well as to the production of beamstrahlung photons and e+e- coherent pairs. In this paper, we present a conceptual design of a 150 m long post-collision extraction line for the CLIC machine at 3 TeV, which separates the various components of the outgoing beam using a vertical magnetic chicane, before transporting them to their respective dump. In addition, detailed studies are performed in order to compute the power losses along the CLIC post-collision line. For the vacuum window at the exit of the post-collision line, we propose a thick (1.5 cm) layer of carbon-carbon composite, with a thin (0.2 mm) aluminum leak-tight foil. The stress levels in this exit window are estimated. Finally, we discuss the use of diagnostics along the post-collision line for monitoring and improving the quality of the e+e- collisions and, in turn, ...

    2016-01-01

    Objective: This review examines studies on mindfulness based programs used with adolescents at-risk for poor future outcomes such as not graduating from high school and living in poverty. Method: The keywords used include mindfulness, at-risk and adolescents in each database to search CINAHL (10 items: 2 book reviews, 3 Dissertations, and 5 research articles), Medline EBSCO (15 research articles), and PubMed (10 research articles). Only primary research articles published between 2009- 2015 in English on mindfulness and at-risk adolescents were included for the most current evidence. Results: Few studies (n= 11) were found that investigate mindfulness in at-risk adolescents. These studies used various mindfulness programs (n = 7) making it difficult to generalize findings for practice. Only three studies were randomized control trials focusing mostly on male students with low socioeconomic status and existing mental health diagnoses. Conclusion: There is a relationship between health behaviors and academic achievement. Future research studies on mindfulness based interventions need to expand to its effects on academic achievement in those youth at-risk to decrease problematic behaviors and improve their ability to be successful adults.

  2. Conceptual, experimental and computational approaches to support performance assessment of hydrology and chemical transport at Yucca Mountain

    International Nuclear Information System (INIS)

    The authors of this report have been participating in the Sandia National Laboratory's hydrologic performance assessment of the Yucca Mountain, Nevada, since 1983. The scope of this work is restricted to the unsaturated zone at Yucca Mountain and to technical questions about hydrology and chemical transport. The issues defined here are not to be confused with the elaborate hierarchy of issues that forms the framework of the US Department of Energy plans for characterizing the site (DOE, 1989). The overall task of hydrologic performance assessment involves issues related to hydrology, geochemistry, and energy transport in a highly heterogeneous natural geologic system which will be perturbed in a major way by the disposal activity. Therefore, a rational evaluation of the performance assessment issues must be based on an integrated appreciation of the aforesaid interacting processes. Accordingly, a hierarchical approach is taken in this report, proceeding from the statement of the broad features of the site that make it the site for intensive studies and the rationale for disposal strategy, through the statement of the fundamental questions that need to be answered, to the identification of the issues that need resolution. Having identified the questions and issues, the report then outlines the tasks to be undertaken to resolve the issues. The report consists essentially of two parts. The first part deals with the definition of issues summarized above. The second part summarizes the findings of the authors between 1983 and 1989 under the activities of the former Nevada Nuclear Waste Storage Investigations (NNWSI) and the current YMP

  3. Conceptual hydrochemical model of late Pleistocene aquifers at the Samario-Sitio Grande petroleum reservoir, Gulf of Mexico, Mexico

    International Nuclear Information System (INIS)

    Carbon-14 concentrations between 0.83 and 11.79 pmC of formation water from the Activo Samaria-Sitio Grande petroleum reservoir in SE-Mexico, extracted from 3500 to 4500 m.b.s.l., indicate a common infiltration event of surface water during the late Pleistocene period. Mixing of two components - meteoric water and seawater, previously evaporated at the surface - explain the widespread mineralization (TDI = 15-257 g/L) of Na-Cl and Na-Ca-Cl type reservoir water. Statistical discrimination by clustering and a heterogeneous chemical-isotopic fluid composition indicate the existence of 4 different water types as part of local aquifer systems, which are separated by normal and thrust faults. Tectonic horst and graben structures show an ambiguous, individual hydraulic behaviour - as permeable conduits and/or as impermeable barriers, causing the local limitation of aquifer extent. The recent increase of water production in petroleum wells is not related to the injection of surface water, but the long-term extraction of oil reserves is modifying the original position and flow direction of the reservoir aquifers. The rise of the initial groundwater level reflects the final stage of an exhausted petroleum reservoir with coning effects of underlying aquifer systems. The flexible change towards superior production intervals could represent a feasible technique to avoid the abrupt closure of invaded production wells

    The Former Radiation Worker Medical Surveillance Program at Rocky Flats was conducted in Arvada, CO, by Oak Ridge Associated Universities through the Oak Ridge Institute for Science and Education under DOE Contract DE-AC05-00OR22750. Objectives of the program were to obtain information on the value of medical surveillance among at-risk former radiation workers and to provide long-term internal radiation dosimetry information to the scientific community. This program provided the former radiation workers of the Rocky Flats Environmental Technology Site (formerly Rocky Flats Plant) an opportunity to receive follow-up medical monitoring and a re-evaluation of their internal radiation dose. The former Rocky Flats radiation worker population is distinctive because it was a reasonably stable work force that received occupational exposures, at times substantial, over several decades. This report reflects the summation of health outcomes, statistical analyses, and dose assessment information on former Rocky Flats radiation workers to the date of study termination as of March 2004.

  9. Ground heating and methane oxidation processes at shallow depth in Terre Calde di Medolla (Italy): Observations and conceptual model

    2015-05-01

    The toponym "Terre Calde di Medolla" (literally, "Warm Earths of Medolla") refers to a farming area, located near the town of Modena (Emilia-Romagna region, northern Italy), which has always been known by the local population for the relatively high temperatures of the soil. This phenomenon is particularly evident in wintertime when the snow cover over this area rapidly melts. A detailed investigation, carried out after the devastating 2012 Emilia earthquake that affected this area, showed soil temperatures up to 44°C, i.e., 20-25°C above the local background value, together with diffuse soil fluxes of CH4 (0-2432 g × m-2 × d-1) and minor, though significant, CO2 (0-1184 g × m-2 × d-1), especially from subcircular (a few meters in diameter) zones. Ground heating and gas seepage appear spatially correlated, thus suggesting a close relationship between the two phenomena. The anomalous high ground temperature is not associated with an anomalous geothermal gradient or with the uprising of deep-seated hot fluids. According to the lateral and vertical distributions of the temperatures as well as the chemical and isotopic compositions of the soil gases, the most reliable explanation is the exothermic oxidation of diffusely uprising biogenic methane at very shallow levels (<1 m). Such a process occurs in the presence of free oxygen and methanotrophic bacteria and can then explain (i) the observed ground heating up, (ii) the diffuse emission from the soil of CO2 characterized by an extremely negative isotopic (13C/12C) signature, and (iii) the lack of diffuse and low CH4 fluxes. According to these hypotheses, the heating phenomena affecting the shallow groundwater and the ground surface, as described by several witnesses in the area of the May-June 2012 Emilia earthquake, could be related to either a coseismic or postseismic onset of new areas affected by CH4 seepage or an increase in preexisting CH4 fluxes.

    The Canadian nuclear power generation industry, represented by the CANDU Owners Group (COG), has been funding an experimental program at Chalk River Laboratories (CRL) to study the interaction between molten material ejected from a fuel channel and the moderator. These experiments were designed to address one of the very low probability postulated accident events considered for CANDU Pressurized Heavy Water Reactors. The reactor consists of an array of horizontal fuel channels that contain the UO{sub 2}, nuclear fuel and high-temperature, high-pressure heavy water coolant. Under severely restricted flow blockage conditions, approaching 100% reduction of the flow area, postulated in a fuel channel, the temperature excursion could result in fuel melting, consequential failure of the fuel channel, and ejection of the molten fuel at high pressures into the heavy water moderator at near atmospheric pressure. In preparation for these tests, a chemical mixture called a thermite, that could produce a simulated molten fuel when ignited, was developed in partnership with Argonne National Laboratory (USA). Following this thermite development, two base-case reference tests were completed. The two base-case reference tests, with no molten material present, were performed in the Molten-Fuel Moderator-Interaction (MFMI) facility at CRL. Following the base-case reference tests, a high-pressure melt ejection test using prototypical corium was conducted. The objectives of this paper are to provide an overview of the MFMI program and present the results obtained from thermite development, base-case and melt ejection experiments. (author)

  12. A program for conducting corrective actions at operating industrial facilities

    International Nuclear Information System (INIS)

    The purpose of this paper is to present a proactive, comprehensive program to assist industries in gaining control over the corrective actions required to address historic contaminant releases (such as oil spills fuel distribution times, and other contaminants such as diesel and jet fuels) while at the same time minimizing their impact on facility operations. In contrast to the approach used by many industries, this program emphasizes a proactive approach in which a strategy is developed to meet the needs of both the facility and the regulators. Development of the strategy includes: conducting a comprehensive self-evaluation of environmental problems; identifying applicable corrective action regulations; developing a risk-based priority ranking of sites requiring corrective actions; preparing an overall strategy/schedule to perform the corrective actions; and obtaining the support/approval of corporate management and the regulators. The program meets the needs of the regulators in that it presents a long-term commitment by the facility to assure the protection of public health and the environment, thereby minimizing enforcement need for regulatory oversight and delays caused by the need for regulatory approvals

  13. Audit program for physical security systems at nuclear power plants

    International Nuclear Information System (INIS)

    Licensees of nuclear power plants conduct audits of their physical security systems to meet the requirements of 10 CFR 73, Physical Protection of Plants and Materials. Section 73.55, Requirements for physical Protection of Licensed Activities in Nuclear Power Reactors Against Radiological Sabotage, requires that the security programs be reviewed at least every 12 months, that the audit be conducted by individuals independent of both security management and security supervision, and that the audit program review all aspects of the physical security system: hardware, personnel, and operational and maintenance procedures. This report contains information for the Nuclear Regulatory Commission (NRC) and for the licensees of nuclear power reactors who carry out these comprehensive audits. Guidance on the overall management of the audit function includes organizational structure and issues concerning the auditors who perform the review: qualifications, independence, due professional care, and standards. Guidance in the audit program includes purpose and scope of the audit, planning, techniques, post-audit procedures, reporting, and follow-up

  14. GCFR Fuels and Materials Program at Argonne National Laboratory

    International Nuclear Information System (INIS)

    The F-5 fuel-pin irradiation experiment in EBR-II is a cornerstone of the GCFR program. It is the largest-scale fuel-pin experiment in the present program and will provide data on the performance of pins and a pin-support structure that are prototypic of the GCFR Demonstration Plant. The fuel pins are presently undergoing interim examination after successfully achieving 4.6 at.% burnup. Studies of the thermodynamics and kinetics of the U--Cs--O system, supplemented by analysis of the results of previously irradiated fuel pins, have led to the incorporation of fuel-design modifications in the F-5 experiment to insure adequate performance of the vented fuel. The effect of ribbing, as well as the ribbing process, on the short- and long-term structural performance of fuel-pin cladding is being evaluated via in-reactor and out-of-reactor tests and with the fuel-element modeling code LIFE-GCFR and the finite element program, ADINA

    The NA61/SHINE experiment at the CERN SPS aims to discover the critical point of strongly interacting matter and study properties of the onset of deconfinement. These goals will be reached by measurements of hadron production properties in nucleus-nucleus, proton-proton and proton-lead interactions as a function of collision energy and size of the colliding nuclei. Furthermore, NA61/SHINE will perform numerous precision measurements needed for neutrino (T2K) and cosmic-ray (Pierre Auger Observatory and KASCADE) experiments. This paper summarizes physics arguments for the NA61/SHINE ion program and presents the status and plans of the experiment.

    In the face of a continuing attention to operations and maintenance costs at nuclear power plants, the future of the industry depends largely upon increasing plant availability and improving operating efficiency. The success in achieving these objectives is dependent upon the success of each plant's equipment maintenance program. Preventing the introduction of foreign materials into a nuclear power plant system or component requires a careful, thoughtful, and professional approach by all site personnel. This paper describes a proactive approach to prevent the introduction of foreign material into systems and components, by providing an overview of technical considerations required to develop, implement, and manage a foreign material exclusion program at CNE Cernavoda Unit 1 and 2 Nuclear Power Station. It is also described an example of Foreign Material Intrusion which happened during the 2003 planned maintenance outage at Cernavoda Unit no.1. This paper also defines personnel responsibilities and key nomenclature and a means for evaluating prospective work tasks and activities against standardized criteria, in order to identify the appropriate level of the required FME controls.

  19. Future of the Beam Energy Scan program at RHIC

    International Nuclear Information System (INIS)

    The first exploratory phase of a very successful Beam Energy Scan Program at RHIC was completed in 2014 with Au+Au collisions at energies ranging from 7 to 39 GeV. Data sets taken earlier extended the upper limit of energy range to the √sNN of 200 GeV. This provided an initial look into the uncharted territory of the QCD phase diagram, which is considered to be the single most important graph of our field. The main results from BES phase I, although effected by large statistical errors (steeply increasing with decreasing energy), suggest that the highest potential for discovery of the QCD Critical Point lies bellow √sNN 20 GeV. Here, we discuss the plans and the preparation for phase II of the BES program, with an order of magnitude larger statistics, which is planned for 2018-2019. The BES II will focus on Au+Au collisions at √sNN from 20 to 7 GeV in collider mode, and from √sNN 7 to 3.5 GeV in the fixed target mode, which will be run concurrently with the collider mode operation

    The Advanced Computer Program at Fermilab has developed a multiprocessor system which is easy to use and uniquely cost effective for many high energy physics problems. The system is based on single board computers which cost under $2000 each to build including 2 Mbytes of on board memory. These standard VME modules each run experiment reconstruction code in Fortran at speeds approaching that of a VAX 11/780. Two versions have been developed: one uses Motorola's 68020 32 bit microprocessor, the other runs with AT and T's 32100. both include the corresponding floating point coprocessor chip. The first system, when fully configured, uses 70 each of the two types of processors. A 53 processor system has been operated for several months with essentially no down time by computer operators in the Fermilab Computer Center, performing at nearly the capacity of 6 CDC Cyber 175 mainframe computers. The VME crates in which the processing ''nodes'' sit are connected via a high speed ''Branch Bus'' to one or more MicroVAX computers which act as hosts handling system resource management and all I/O in offline applications. An interface from Fastbus to the Branch Bus has been developed for online use which has been tested error free at 20 Mbytes/sec for 48 hours. ACP hardware modules are now available commercially. A major package of software, including a simulator that runs on any VAX, has been developed. It allows easy migration of existing programs to this multiprocessor environment. This paper describes the ACP Multiprocessor System and early experience with it at Fermilab and elsewhere.

  3. Research and development program on dense TPC's at LBL

    International Nuclear Information System (INIS)

    We have initiated a research and development program at LBL to develop high density TPC's. We are motivated by their potential use as tracking calorimeters to study nucleon decay. They may also be useful in the study of cosmic neutrino fluxes, double β decay and other low rate processes. Of these applications, the use of dense TPC's to study nucleon decay is the most challenging one because it requires instrumenting very large masses. Our R and D program is aimed at developing large TPC's which are competitive in cost with other proposed nucleon decay detectors while offering superior capabilities for energy resolution, particle identification and uniformity of response. There are two ways of obtaining high density TPC's: the first is to use a cryogenic liquid such as liquid argon or liquid methane; the second is to pressurize a gas such as argon or methane to several hundred atmospheres where the density of the gas approaches that of the liquid state. While we are interested in studying both approaches, we are concentrating on the high pressure approach since it offers the potential advantage of proportional wire amplification. A wire amplification of about 3 orders of magnitude would eliminate the noise problems which are inherent in ionization mode detectors such as liquid argon chambers. A possible 10 kton detector is described, and its properties are discussed in terms of tracking, energy measurements and particle identification

Examples of environmental applications of AMS at Lucas Heights include: use of the {sup 14}C bomb pulse to determine the age and age-spread of air trapped in Antarctic ice bubbles, key parameters to study the variability of CO{sub 2} and other greenhouse gases in the past; analyses of {sup 14}C bomb-pulse curves in tree rings from tropical regions and the southern hemisphere to improve our understanding of the carbon cycle and air-sea interactions, important processes for the global climate; analyses of {sup 10}Be and {sup 36}Cl produced in-situ in polished glacial bedrock and moraine boulders from Tasmania, New Zealand and Antarctica, as part of a major national project to unravel the timing of glacial cycles in the southern hemisphere. A recent archaeological application has been the radiocarbon dating of charcoal fragments from the rock shelter at Jinmium in the Northern Territory demonstrating that this site was occupied by Aboriginal people only during the late Holocene. In environmental monitoring, the analysis of {sup 129}I, {sup 14}C and {sup 36}Cl in water specimens from Mururoa and Fangatauga contributed to an IAEA study regarding residual radioactivity in the Pacific after the French nuclear program Extended abstract. 5 refs.

  5. Configuration Management Program Application at KNPP Units 5 and 6 Modernization Program

    International Nuclear Information System (INIS)

    The need for Configuration Management Program development, became very clear after the initiation of the Modernization Program for Units 5and6, because KNPP personnel needed a good and safe way to control the huge amount of data which were transferred into two directions - input data (design and operational documents from KNPP to Contractors) and the design, vendor, procurement, etc. documents (from Contractors to KNPP). Moreover, most of the measures are in fact design changes and it appeared to be extremely important to track these design changes and their reflection into design and operational documents. It is even more important to obtain a successful transfer of all this information to the operating organization (EP-2) after the completion. The proposal for development of Configuration Management (CM) Program for KNPP Units 5and6 Modernization program was divided into three phases: 1. Information Control (Document Control and Records Management) 2.Technical Decision System (Change Control) 3. Master Equipment List (MEL), (as part of the Design requirements element) Information Control Element was chosen to be developed first. Implementation of Information Control element comprised of: Review and assessment of existing situation (procedures for document control and records Management), Development of new/revision of existing procedure for Document Control and Records Management, Development of SmartDoc software application in support of document control and records management and for measure documentation tracking (with its specifics), Data entry for MP5and6 measures, Implementation at EP-2 (with successful data migration from the existing databases). The SmartDoc development was completed at the end of 2002 and after a testing period it was implemented at Modernization and Investment Department first. Then the data for documents were transferred from the existing databases at EP-2 and the system was implemented at EP-2 and other KNPP facilities. Development

    The Center of Applied Space Technology and Microgravity (ZARM) founded by Prof. Dr.-Ing. Hans J. Rath in 1985 is part of the Department of Production Engineering at the University of Bremen, Germany. ZARM established as a research center and currently headed by Prof. Dr. Claus Lämmerzahl is mainly concentrated on fundamental investigations of gravitational and space-related phenomenas under conditions of weightlessness as well as questions and developments related to technologies for space. At ZARM more than 70 scientists, engineers and administrative staff as well as many students from different departments are employed. Today, ZARM is still one of the largest and most important university institutes for space sciences and technologies in Europe as well as worldwide well known in the space community. With a height of 146 m the Bremen Drop Tower is the predominant facility of ZARM and also the only drop tower of its class in Europe. ZARM’s ground-based laboratory offers the opportunity for daily short-term experiments under conditions of high-quality weightlessness at a level of 10 (-6) g (microgravity). The provided quality is one of the purest for experiments under weightlessness worldwide achieved. The scientists may choose between a single drop experiment with 4.74 s in simple free fall and a catapult experiment with 9.3 s of weightlessness. Either in the drop or in the worldwide unique catapult operation routine the repetition rates of microgravity experiments at ZARM are always the same, generally up to 3 times per day. Since the start of operation of the facility in 1990, over 6750 launches of more than 160 different experiment types from various scientific fields like Fundamental Physics, Combustion, Fluid Dynamics, Planetary Formation / Astrophysics, Biology and Materials Sciences have been successfully accomplished so far. In our paper we will report and inform about microgravity experiment programs for students like „Drop Your Thesis!“ by ESA and

    In this talk we present an ongoing effort to develop an undergraduate research training program in geosciences at North Carolina A&T State University. The National Science Foundation HBCU Undergraduate Program (HBCU-UP) funded in 1999 the University's Talent-21: Gateway for Advancing Science and Mathematics Talent. Defined in the Talent-21 Project is a research training component where a facility has been situated for undergraduate research training in the geophysical and environmental sciences. Planned for the undergraduate geophysical research training program is a three-pronged approach of generating (1) real-world seismic data by seismic field surveys, (2) physical modeled data through the Seismic Physical Modeling System, and (3) computer simulated data through mathematical modeling and numerical simulation to mutually refine understanding of site, the data, and the methods selected for testing. The results will be used to build models that simulate earth subsurface structures. This research training program aims to expose students to theory via topical seminars and workshops, and to practice via hands-on experience in field geophysical surveying, comparative field data analysis, physical modeling, computational modeling, and synthetic seismic data acquisition. It offers structured education and training activities that guide experiences in geophysical topics and techniques, and research for students to increase interest and participation in geophysical science with STEM career development. Students usually start the program with academic year research training to prepare themselves for research projects, and continue their pursuit through intensive summer REU program to undertake research projects and write project reports. Students are encouraged to present their research results at regional or national undergraduate research conferences. Four summer REU programs have been conducted since 2001, and some of the student research projects and results will be

    The University of Texas at El Paso (UTEP) is located on 300 acres, only a few hundred years from the US/Mexico border. The DOE Infrastructure Support Program was initiated at UTEP in 1987. The purpose of the program was to assist the University in building the infrastructure required for its emerging role as a regional center for energy-related research. Equally important was the need to strength the University`s ability to complete for sponsored energy-related programs at the state and national levels and to provide opportunities for faculty, staff and students to participate in energy-related research and outreach activities. The program had four major objectives, as follows: (1) implement energy research, outreach and demonstration projects already funded, and prepare new proposals to fund university research interests; (2) establish an Energy Center as a separate operational entity to provide continuing infrastructure support for energy-related programs; (3) strengthen university/private sector energy research linkages; and (4) involve minority graduate and undergraduate students in energy research and outreach activities. Each of the above objectives has been exceeded substantially, and, as a consequence, the University has become a regional leader in energy and environmental research and outreach efforts.

    1991-10-01

    The Texas A M experimental high energy physics program continued to reach significant milestones in each of its research initiatives during the course of the past year. We are participating in two major operating experiments, CDF and MACRO. In CDF, the Texas A M group has spearheaded the test beam program to recalibrate the Forward Hadron Calorimeter for the upcoming CDF data run, as well as contributing to the ongoing analysis work on jets and b-quarks. In MACRO, we have assisted in the development of the final version of the wave form digitizing system being implemented for the entire scintillator system. The construction of the first six supermodules of the detector has been completed and all six are currently taking data with streamer chambers while four have the completed scintillator counter system up and running. We have built and tested prototypes of a liquid-scintillator fiber calorimeter system, in which internally reflecting channels are imbedded in a lead matrix and filled with liquid scintillator. This approach combines the performance features of fiber calorimetry and the radiation hardness of liquid scintillator, and is being developed for forward calorimetry at the SSC. The microstrip chamber is a new technology for precision track chambers that offers the performance required for future hadron colliders. The theoretical high energy physics program has continued to develop during the past funding cycle. We have continued the study of their very successful string-derived model that unifies all known interactions; flipped SU(5), which is the leading candidate for a TOE. Work has continued on some generalizations of the symmetries of string theory, known as W algebras. These are expected to have applications in two-dimensional conformal field theory, two-dimensional extensions of gravity and topological gravity and W-string theory.

  12. Development of a Conceptual Model for Vadose Zone Transport of Tc-99 at Hanford's BC Cribs and the Screening of Remedial Alternatives

    International Nuclear Information System (INIS)

    A number of waste trenches and cribs at Hanford's BC Cribs and Trenches site, which received about 10 Mgal of scavenged tank waste with elevated concentrations of technetium-99 and nitrate, are being evaluated for remediation. The objectives of this study were to: 1) develop a conceptual model for vadose zone transport of mobile contaminants, and 2) investigate the effects of fine-scale heterogeneity (i.e. horizontal laminations, cross-bedding) on the large-scale transport behavior with the goal of developing an appropriate remedial strategy. The vertical heterogeneity structure, conditioned on grain size distributions and borehole geophysical logs (water content and natural isotopes), was developed from a single borehole at the site. Geostatistical methods were used to impose a 3-D spatial correlation structure, using information from an adjacent well-characterized experimental site, and to merge heterogeneities at various scales. Flow and transport properties were derived using property transfer models based on grain size distributions. The STOMP simulator was used to predict flow and transport through the vadose zone and into a 5-m thick confined aquifer during the period of trench operations (1956-1958) through to the present time. Results show that fine-scale heterogeneity within the large-scale lithologic units enhanced lateral flow and mixing, limited vertical penetration in the vadose zone, and played a critical role in keeping contaminants above the water table. Model results show good agreement with a contaminant profile from a borehole installed in the 216-B-26 trench. Simulated distributions of nitrate and electrical resistivity are also in good agreement with the results of a field-scale resistivity survey. These results suggest that installation of an engineered surface barrier would reduce the threat to ground water by reducing the mass flux of contaminants to the water table and increasing the residence time in the vadose zone.

The extreme conditions created by the collisions within a finite volume are akin to the properties of the deconfined partonic state which existed very shortly after the Big Bang and just prior to visible matter formation in the Universe. In this state massless quarks and gluons (partons) are ``quasi free" particles, the so-called Quark Gluon Plasma (QGP). By following the expansion and cooling of this state, we will map out the process of nucleonic matter formation, which occurs during the phase transition. The fundamental properties of this early partonic phase of matter are not well understood but they are essential for confirming QCD (Quantum Chromo-Dynamics) and the Standard Model. The specific topic, chiral symmetry restoration, has been called ``the remaining puzzle of QCD.'' This puzzle can only be studied in the dense partonic medium generated in heavy-ion collisions. The research objectives of this proposal are the development and application of new analysis strategies to study chirality and the properties of the medium above the QGP phase transition using hadronic resonances detected with the ALICE experiment at the Large Hadron Collider (LHC) at the CERN research laboratory in Switzerland. This grant funded a new effort at the University of Texas at Austin (UT Austin) to investigate the Quark Gluon Plasma (QGP) at the highest possible energy of 2.76 TeV per nucleon at the Large Hadron Collider (LHC) at CERN via the ALICE experiment.

    The high energy physics program has continued its experimental activities over. In CDF, the Texas A M group has led an effort to design an upgrade for the silicon vertex detector, and is currently working with the rest of the collaboration on the next major data taking run. In MACRO, work was done on the development of the final version of the wave form digitizing system being implemented for the entire scintillator system. This work is nearing completion, and the system is expected to be up and running on the detector by summer 1993. Work was done within the SDC group to develop gas microstrip chambers for use in precision tracking at the SSC, and in the GEM group, toward the development of a suitable forward calorimeter design. The theoretical high energy physics program has continued the study of a very successful string-derived model that unifies all known interactions: flipped SU(5), which is the leading candidate for a TOE. Work has also continued on some generalizations of the symmetries of string theory, known as W algebras. These are expected to have applications in two-dimensional conformal field theory, two-dimensional extensions of gravity and topological gravity and W-string theory.

  18. Radiation protection program at an accelerator facility complex

    International Nuclear Information System (INIS)

    Broad aspects of Radiation Protection Program at the Tyco Healthcare/Mallinckrodt Inc. will be presented with emphasis on Occupational dose, Public dose and ALARA program. Regulatory requirements, compliance and radio nuclides of concern for external exposure and internal contamination will be discussed. The facility is subject to in depth annual inspections by the Nuclear Regulatory Commission (NRC) to ensure compliance with regulations and operating license requirements. The facility is required to have an emergency contingency plan in place. A simulated emergency drill scenario is witnessed and graded by the NRC and state inspectors, with full participation by the fire department and the local hospital. Radiation Safety Officer (RSO) is in charge of all radiological aspects of the facility, and reports to the plant manager directly. The RSO or any of his staff has the authority to stop a job if there is a radiological concern. The Radiation protection organization interfaces with Production, QA and Engineering and ensures there is no conflict with Industrial Safety, OSHA and FDA requirements. Any employee has the right to call the regulatory officials if he/she has a concern. Operational aspects of Radiation protection program such as radiological survey, contamination control and limits, air sample survey, radio active waste processing and record retention requirements are per plant procedures and regulatory requirements. Shielding and administrative requirements for designing a modification to an existing design or a new lab/hot cell is subject to in-depth review and approval by Radiation Safety Committee. Each department has a Dose Reduction Subcommittee which meets periodically to discuss if any changes in procedures or facility can be made to decrease the dose. The subcommittee also trends the dose to ensure it is trending downward. Even though 99Mo/99mTC generators are manufactured at the facility, majority of the dose is from cyclotron maintenance. Total

    There are strong experimental and theoretical evidences that in collisions of heavy ions at relativistic energies nuclear matter undergoes a phase transition to the deconfined state—Quark Gluon Plasma. The caused energy region of such transition was not found at high energy at SPS and RHIC and search for this energy is shifted to lower energies, which will be covered by the future NICA (Dubna), FAIR (Darmstadt) facilities and BES II at RHIC. Fixed target and collider experiments at the NICA facility will work at the energy range from a few AGeV up to √ {{S_{NN}}} = 11GeV GeV and will study the most interesting area on the nuclear matter phase diagram. The most remarkable results were observed in the study of collective phenomena occurring in the early stage of nuclear collisions. Investigation of the collective flow will provide information on Equation of State (EoS) for nuclear matter. Study of the Event-by-Event fluctuations and correlations can give us signals of critical behavior of the system. Femtoscopy analysis provides the space-time history of the collisions. Also, it was found that baryon stopping power revealing itself as a "wiggle" in excitation function of curvature of the (net)proton rapidity spectrum relates to the order of the phase transition. The available observations of an enhancement of dilepton rates at low invariant masses may serve as a signal of the chiral symmetry restoration in hot and dense matter. Due to this fact, measurements of the dilepton spectra are considered to be an important part of the NICA physics program. The study of strange particles and hypernuclei production gives additional information on the EoS and "strange" axis of the QCD phase diagram. In this paper a feasibility of the considered investigations is shown by the detailed Monte Carlo simulations applied to the planned experiments (BM@N, MPD) at NICA.

    1996-10-01

    The US Department of Energy`s Defense Programs face unprecedented challenges of stewardship for an aging nuclear stockpile, cessation of nuclear testing, reduced federal budgets, and a smaller manufacturing complex. Partnerships with industry are essential in developing technology, modernizing the manufacturing complex, and maintaining the safety and reliability of the nation`s nuclear capability. The past decade of federal support for industrial partnerships has promoted benefits to US industrial competitiveness. Recent shifts in government policy have re-emphasized the importance of industrial partnerships in accomplishing agency missions. Nevertheless, abundant opportunities exist for dual-benefit, mission-driven partnerships between the national laboratories and industry. Experience at Los Alamos National Laboratory with this transition is presented.

    Objective: To provide a conceptual framework for managing diabetic patient care, and creating an information network for clinical research. Background: A wide range of information technology (IT) based interventions such as distance learning, diabetes registries, personal or electronic health record systems, clinical information systems, and clinical decision support systems have so far been used in supporting diabetic care. Previous studies demonstrated that IT could improve diabetes care at its different aspects. There is however no comprehensive conceptual framework that defines how different IT applications can support diverse aspects of this care. Therefore, a conceptual framework that combines different IT solutions into a wide information network for improving care processes and for research purposes is widely lacking. In this study we describe the theoretical underpin of a big project aiming at building a wide diabetic information network namely DIANET. Research design and methods: A literature review and a survey of national programs and existing regulations for diabetes management was conducted in order to define different aspects of diabetic care that should be supported by IT solutions. Both qualitative and quantitative research methods were used in this study. In addition to the results of a previous systematic literature review, two brainstorming and three expert panel sessions were conducted to identify requirements of a comprehensive information technology solution. Based on these inputs, the requirements for creating a diabetes information network were identified and used to create a questionnaire based on 9-point Likert scale. The questionnaire was finalized after removing some items based on calculated content validity ratio and content validity index coefficients. Cronbach’s alpha reliability coefficient was also calculated (αTotal= 0.98, P<0.05, CI=0.95). The final questionnaire was containing 45 items. It was sent to 13 clinicians at two

    Among other goals, the Chronic Disease Self-Management Program (CDSMP) is designed to improve self-efficacy of the chronically ill. However, a substantial proportion of the enrollees often leave CDSMPs before completing the program curriculum. This study examines factors associated with program attrition in a CDSMP implemented in a community setting. We used data from the Our Pathways to Health program, implemented in Humboldt County, California, from 2008 to 2011. Our conceptual framework is based on Bandura's self-efficacy theory, and we used logistic regression to investigate whether baseline self-efficacy and other members' efficacy are associated with participants dropping out of the CDSMP. Twenty-three percent of the participants did not complete the program similar to previous studies. Lower baseline self-efficacy increased the odds of dropout, but other members' efficacy was not associated with differential odds of dropout. Age, educational difference between the individual and the group, weekday sessions, and social/role activity limitations are also found to be associated with program attrition. Our results suggest that participants with low starting self-efficacy may need extra help to complete the program. Further research is needed to understand how to effectively provide additional support to this group.

  6. The meson spectroscopy program with CLAS12 at Jefferson Laboratory

    The study of the hadronic spectrum is one of the most powerful tools to investigate the mechanism at the basis of quark confinement within hadrons. A precise determination of the spectrum allows not only to assess the properties of the hadrons in their fundamental and excited states, but also to investigate the existence of states resulting from alternative configurations of quarks and gluons, such as the glue-balls, hybrid hadrons and many-quarks configurations. The study of the mesonic part of the spectrum can play a central role in this investigation thanks to the strong signature that the hybrid mesons are expected to have: the presence of explicit gluonic degrees of freedom in such states may result in JPC configurations not allowed for the standard q ¯ q states. From the experimental side the expected high-multiplicity decays of the hybrid mesons require an apparatus with high performances in terms of rate-capability, resolution and acceptance. The CLAS12 experiment (formally MesonEx) is one of new-generation experiments at Thomas Jefferson National Laboratory (JLAB) for which an unprecedented statistics of events, with fully reconstructed kinematics for large particle multiplicity decays, will be available. A wide scientific program that will start in 2016 has been deployed for meson spectrum investigation with the CLAS12 apparatus in Hall B at energies up to 11 GeV. One of the main parts of the program is based on the use of the Forward Tagger apparatus, which will allow CLAS12 experiment to extend the study of meson electro-production to the quasi-real photo-production kinematical region (very low Q2), where the production of hybrid mesons is expected to be favoured. The data analysis which is required to extract the signal from hybrid states should go beyond the standard partial wave analysis techniques and a new analysis framework is being set up through the international network Haspect. The Haspect Network gathers people involved into theoretical and

    Lal, R.; Tan, A.; Lyatsky, W.

    A new undergraduate Physics Program with Space Science as the major concentration area has been initiated at Alabama A&M University (AAMU) in 2001. This program is funded by NASAÆs OSS and OEOP Offices under the NRA 00-OSS-02 Minority University Education and Research Partnership Initiative in Space Science-2000. The partner institutions are NASA Marshall Space Flight Center (MSFC) and Goddard Space Flight Center (GSFC), Lawrence Livermore National Laboratory (LLNL) and The University of Alabama in Huntsville (UAH). A primary objective of this Program is to train undergraduate and graduate minority (principally African-American) students in the extremely underrepresented areas of Space Science and to prepare them for eventual teaching and/or research careers in this increasingly important field. The best way to achieve this is to recruit students early from high school, and not wait until they have already selected their specialty in college. Also, a student with a BS degree in Physics with specialization in Space Science will have a decisive advantage in pursuing graduate studies in Space Science than the others. The BS degree requires a student to take 30 credit hours of Physics courses and an additional 18 hours in the chosen area of concentration. Several basic traditional courses in Lower Atmosphere, Aeronomy, the Solar System and Orbital Mechanics have been developed. Additional courses in Plasma Physics, Solar Physics and Astronomy will be taught by NASA-MSFC scientists and UAH faculty. A parallel objective is to expose the student to research experience early in their ca- reers. Each student is required to complete a one semester Undergraduate Research Opportunity Project (UROP) on a relevant topic from Space Science. The students will be guided in research by AAMU and UAH faculty and MSFC scientists. Each student will be required to write a term paper and make an oral presentation before a committee of advisors. This experience will enhance the Space

    An authentic science research program in the classroom can take many forms as can the teacher professional development that accompanies the programs. One different approach invites educators to invoke 21st century skills with their students while focusing on a real-world issue of both local and global concern. The citizen-science program on light pollution, GLOBE at Night, has students and the general public measure the darkness of their local skies and contribute observations online to a world map. They do this by looking toward Orion for the faintest stars and matching what they see to one of seven different star maps. (For more precise measurements, digital sky-brightness meters are used.) These measurements can be compared with data from the previous 4 years, as well as with satellite data, population densities, and electrical power-usage maps. Measurements can be examined online via Google Earth or other tools and are downloadable as datasets from the website. Data from multiple locations in one city or region are especially interesting, and have been used as the basis of research in a classroom or science fair project or even to inform the development of public policy. This year, GLOBE at Night has been expanding its role in training educators on fundamental concepts and data collection to include more data analysis for a topical variety of local projects. Many on-site workshops have and are being given to teachers in grades 5 through high school. Some of the U.S. school communities created mini-campaigns that combined local students with public advocates and representatives from local city and county governments, and also collaborated with students in Wales, Canada, Romania and north-central Chile (near major observatories). Internationally, training has been given via on-line forums, telecon-powerpoint presentations, videoconferencing via Skype, and blogs. Informal educators have come from national and international networks of science, technology and

    2005-01-01

    At PEP-II, seven large power supplies (LGPS) are used to power quad magnets in the electron-positron collider region. The LGPS ratings range from 72kW to 270kW, and were installed in 1997. They are unipolar off-line switch mode supplies, with a 6 pulse bridge rectifying 480VAC, 3-phase input power to yield 650VDC unregulated. This unregulated 650VDC is then input into one (or two) IGBT H-bridges, which convert the DC into PWM 16 kHz square wave AC. This high frequency AC drives the primary side of a step-down transformer followed by rectifiers and low pass filters. Over the years, these LGPS have presented many problems mainly in their control circuits, making it difficult to troubleshoot and affecting the overall accelerator availability. A redesign/rebuilding program for these power supplies was established under the coordination of the Power Conversion Department at SLAC. During the 2004 accelerator summer shutdown all the control circuits in these supplies were redesigned and replaced. A new PWM control b...

    1993-01-29

    The PHENIX Conceptual Design Report (CDR) describes the detector design of the PHENIX experiment for Day-1 operation at the Relativistic Heavy Ion Collider (RHIC). The CDR presents the physics capabilities, technical details, cost estimate, construction schedule, funding profile, management structure, and possible upgrade paths of the PHENIX experiment. The primary goals of the PHENIX experiment are to detect the quark-gluon plasma (QGP) and to measure its properties. Many of the potential signatures for the QGP are measured as a function of a well-defined common variable to see if any or all of these signatures show a simultaneous anomaly due to the formation of the QGP. In addition, basic quantum chromodynamics phenomena, collision dynamics, and thermodynamic features of the initial states of the collision are studied. To achieve these goals, the PHENIX experiment measures lepton pairs (dielectrons and dimuons) to study various properties of vector mesons, such as the mass, the width, and the degree of yield suppression due to the formation of the QGP. The effect of thermal radiation on the continuum is studied in different regions of rapidity and mass. The e[mu] coincidence is measured to study charm production, and aids in understanding the shape of the continuum dilepton spectrum. Photons are measured to study direct emission of single photons and to study [pi][sup 0] and [eta] production. Charged hadrons are identified to study the spectrum shape, production of antinuclei, the [phi] meson (via K[sup +]K[sup [minus

    Brookhaven National Laboratory has prepared a conceptual design for a world class user facility for scientific research using synchrotron radiation. This facility, called the ''National Synchrotron Light Source II'' (NSLS-II), will provide ultra high brightness and flux and exceptional beam stability. It will also provide advanced insertion devices, optics, detectors, and robotics, and a suite of scientific instruments designed to maximize the scientific output of the facility. Together these will enable the study of material properties and functions with a spatial resolution of {approx}1 nm, an energy resolution of {approx}0.1 meV, and the ultra high sensitivity required to perform spectroscopy on a single atom. The overall objective of the NSLS-II project is to deliver a research facility to advance fundamental science and have the capability to characterize and understand physical properties at the nanoscale, the processes by which nanomaterials can be manipulated and assembled into more complex hierarchical structures, and the new phenomena resulting from such assemblages. It will also be a user facility made available to researchers engaged in a broad spectrum of disciplines from universities, industries, and other laboratories.

    Full Text Available This article has at its core the unraveling of factors that have influenced the identity of those who have been caught in between two worlds (Mexico and The United States and whom will be called pre- and in-service returnees from now on. A qualitative approach was chosen in order to delve deep into the participants’ lived experiences through narrative inquiry which in turn aided in the discovery of the elements that have influenced their identity construction. The data suggest that those same elements have been crucial in the creation of a small culture among the participants at a teacher education program in teaching English to speakers of other languages at a Mexican university.Este artículo se centra en aclarar algunos de los factores que influyen en la identidad de las personas que se han visto atrapadas entre dos “mundos” (México y Estados Unidos, también conocidas como los “retornados”. Se optó por un método cualitativo para ahondar en sus experiencias vividas mediante la indagación narrativa, la cual a su vez aportó al descubrimiento de elementos que influyen en la construcción de sus identidades. Los datos sugieren que esos mismos elementos son de suma importancia en la constitución de una pequeña cultura dentro de la licenciatura en la enseñanza de inglés a hablantes de otras lenguas, en una universidad mexicana.

  5. Short-lived radionuclides program at the University of Michigan

    International Nuclear Information System (INIS)

    The University of Michigan Nuclear Medicine Research Program, from instrumentation design through radiopharmaceutical development to clinical evaluation, is heavily dependent on the availability and use of iodine-123. Research activities at the University of Michigan can be divided into four major areas: instrumentation, radiochemistry, radiopharmaceutical development, and clinical evaluation. In the first category a new single-photon ring tomograph (SPRINT) has been built and is undergoing performance testing. SPRINT has been designed specifically for brain imaging with 123I-labeled agents. In the area of radiochemistry, a simple radioiodide exchange technique has been developed for the rapid synthesis of 123I-labeled aromatic compounds. In the radiopharmaceutical arena, a new agent, 123I-meta-iodobenzyl-guanidine (MIBG), has been developed - the result of an extensive structure-distribution-relationship study. This radiopharmaceutical, a storage analog of norepinephrine, images organs with rich sympathetic innervation such as the heart and spleen. In the Nuclear Medicine Clinic three 123I-labeled radiopharmaceuticals are undergoing evaluation

  6. Earthquake safety program at Lawrence Livermore National Laboratory

    International Nuclear Information System (INIS)

    Within three minutes on the morning of January 24, 1980, an earthquake and three aftershocks, with Richter magnitudes of 5.8, 5.1, 4.0, and 4.2, respectively, struck the Livermore Valley. Two days later, a Richter magnitude 5.4 earthquake occurred, which had its epicenter about 4 miles northwest of the Lawrence Livermore National Laboratory (LLNL). Although no one at the Lab was seriously injured, these earthquakes caused considerable damage and disruption. Masonry and concrete structures cracked and broke, trailers shifted and fell off their pedestals, office ceilings and overhead lighting fell, and bookcases overturned. The Laboratory was suddenly immersed in a site-wide program of repairing earthquake-damaged facilities, and protecting our many employees and the surrounding community from future earthquakes. Over the past five years, LLNL has spent approximately $10 million on its earthquake restoration effort for repairs and upgrades. The discussion in this paper centers upon the earthquake damage that occurred, the clean-up and restoration efforts, the seismic review of LLNL facilities, our site-specific seismic design criteria, computer-floor upgrades, ceiling-system upgrades, unique building seismic upgrades, geologic and seismologic studies, and seismic instrumentation. 10 references

    Full Text Available Educators at Sograndio Juvenile Detention Center in Asturias were sure that they were able to offer new alternatives to improve their socio-educational intervention. That is the reason why they got involved in an action research training process aimed at making didactic proposals which tried to optimize the development of social competence programs for youngsters with criminal behavior. In order to do this, the Short Version of the Prosocial Thinking Program for Young People (Alba et al., 2005 was applied to nine inmates, eight males between 14 and 20 years old and a female of 16 years old. Theywere the basis and reflection of ourmethodological intervention. The teamtaking part in this intervention is formed by nine inmates and three external members (two coordinators and a woman psychologist. The investigation, mainly qualitative, includes different instruments (both qualitative and quantitative, such as: observation registries, discussion groups, questionnaires and notebooks. After the implementation of the program, positive changes must be highlighted in the emotional dimension, the resolution of problems, self-control and frustration tolerance. Besides, very high levels of satisfaction have been observed among youngsters, educators and external informants. It is important to have created a climate of professional compromise towards change and this way to have abandoned a passive attitude towards training, so that we were able to start an active search for practical answers, adjusted to our necessities and professional interests. Finally, we make several observations and intervention proposals that contribute to generate didactic knowledge thought and adapted for social education.

    We discuss the results on the fundamental degrees of freedom underlying the nucleon excitation spectrum and how they evolve as the resonance transitions are investigated with increasingly better space-time resolution of the electromagnetic probe. Improved photocouplings for a number of resonant states, those for the N(1720)P13 being significantly changed, have been determined and entered into the 2008 edition of the RPP. Strong sensitivity to the N(1900)P13 state, listed now as a 2-star state in the same edition of RPP, has been observed in KΛ and KΣ photoproduction. None of the earlier observations of a Θ+5(1540) was confirmed in a series of three Jefferson Lab high statistics dedicated measurements, and stringent upper limits on production cross sections were placed in several channels. For the four lowest excited states, the Δ(1232)P33, N(1440)P11, N(1520)D13, and N(1535)S11, the transition amplitudes have been measured in a wide range in photon virtuality Q2. The amplitudes for the Δ(1232) show the importance of the pion-cloud contribution and do not show any sign of approaching the pQCD regime for Q2 photo- and electroproduction data allowed one to specify the branching ratios of this state to the πN and ηN channels; they entered into the 2010 edition of the RPP. Measured for the first time, the longitudinal transition amplitude for the N(1535)S11 became a challenge for quark models and can be indicative of large meson-cloud contributions or alternative representations of this state. The N(1520)D13 clearly shows the rapid changeover from helicity-3/2 dominance at the real photon point to helicity-1/2 dominance at Q2 > 0.5 GeV2 confirming a long-standing prediction of the constituent quark model. The search for undiscovered but predicted states continues to be pursued with a vigorous experimental program. While recent data from Jefferson Lab and elsewhere provide intriguing hints of new states, final conclusions will have to wait for the results of the

    injectors, but can be a consideration in preburners, where the desire to keep turbine inlet temperatures as cool as possible can make it advantageous for the preburners to operate as far from stoichiometry as can be tolerated. For some missions such as single stage to orbit, all of the above requirements must be maintained over a throttleable range, for example 5:1 to 10:1. Finally, the injectors must be ignitable during startup where pressures and temperatures are far from design conditions, and ignition transients must be minimized in order to avoid damage to engine components. In order to satisfy these various constraints, the injector designer must be able to perform design tradeoff studies, and it is important that this be done with minimal time and costs. In fact, it can easily be argued that reducing engine development time and costs is essential to maintaining U.S. competitiveness in space. The Propulsion Directorate of the Phillips Laboratory has invested in a number of programs to advance liquid rocket engine technology, and several of these are directed at improving design tools for liquid rocket injectors. The purpose of the presentation will be to describe some of these latter programs.

    The Solar Dynamics Observatory (SDO) Education and Public Outreach (E/PO) program began as a series of discrete efforts implemented by each of the instrument teams and has evolved into a well-rounded program with a full suite of national and international programs. The SDO E/PO team has put forth much effort in the past few years to increase our cohesiveness by adopting common goals and increasing the amount of overlap between our programs. In this paper, we outline the context and overall philosophy for our combined programs, present a brief overview of all SDO E/PO programs along with more detailed highlight of a few key programs, followed by a review of our results up to date. Concluding is a summary of the successes, failures, and lessons learned that future missions can use as a guide, while further incorporating their own content to enhance the public's knowledge and appreciation of NASA?s science and technology as well as its benefit to society.

    2002-11-01

    Acoustics, essentially a multidisciplinary subject, still has in Brazil a small but increasing number of professionals with a solid background to deal with various aspects of this area. Since 1970 the faculty of the Acoustics and Vibration Laboratory, COPPE/UFRJ, offers graduate (M.Sc and D.Sc) programs, and some undergraduate courses in acoustics, vibration, and signal processing. In January 2000, this group launched a formal undergraduate engineering acoustics program in the Mechanical Engineering Department of the Federal University of Rio de Janeiro. After three years of mechanical engineering, with a firm foundation in physics, applied mathematics, and engineering basics, the undergraduate student may elect to take the engineering acoustics program for the remaining two years. In this program, a wide number of courses are offered, including basic acoustics, room acoustics, signal processing, musical acoustics, machine diagnosis, etc. Approximately 30 different courses may be chosen from. However, the student is not completely free, since the courses selected must fit within a subject concentration profile, e.g., noise control or musical acoustics. In this paper the programs curriculum are presented and its impact on the students is discussed. A first evaluation of the qualifications achieved by the graduate students in the area is also presented.

  10. PHENIX Conceptual Design Report

    International Nuclear Information System (INIS)

    The PHENIX Conceptual Design Report (CDR) describes the detector design of the PHENIX experiment for Day-1 operation at the Relativistic Heavy Ion Collider (RHIC). The CDR presents the physics capabilities, technical details, cost estimate, construction schedule, funding profile, management structure, and possible upgrade paths of the PHENIX experiment. The primary goals of the PHENIX experiment are to detect the quark-gluon plasma (QGP) and to measure its properties. Many of the potential signatures for the QGP are measured as a function of a well-defined common variable to see if any or all of these signatures show a simultaneous anomaly due to the formation of the QGP. In addition, basic quantum chromodynamics phenomena, collision dynamics, and thermodynamic features of the initial states of the collision are studied. To achieve these goals, the PHENIX experiment measures lepton pairs (dielectrons and dimuons) to study various properties of vector mesons, such as the mass, the width, and the degree of yield suppression due to the formation of the QGP. The effect of thermal radiation on the continuum is studied in different regions of rapidity and mass. The eμ coincidence is measured to study charm production, and aids in understanding the shape of the continuum dilepton spectrum. Photons are measured to study direct emission of single photons and to study π0 and η production. Charged hadrons are identified to study the spectrum shape, production of antinuclei, the φ meson (via K+K- decay), jets, and two-boson correlations. The measurements are made down to small cross sections to allow the study of high pT spectra, and J/ψ and Υ production. The PHENIX collaboration consists of over 300 scientists, engineers, and graduate students from 43 institutions in 10 countries. This large international collaboration is supported by US resources and significant foreign resources

  11. Research in Psychiatry: Concepts and Conceptual Analysis.

    Marková, Ivana S; Berrios, German E

    2016-01-01

    Current research in psychiatry is increasingly focused on empirical studies with methods and technologies adopted from medicine. This paper argues that psychiatry has a different epistemological basis from medicine, and it is on account of this that research in psychiatry demands a different approach, one that perforce focuses on the clarification of concepts central to psychiatric practice. This means undertaking conceptual analysis and conceptual history and only then moving on to empirical study. This paper highlights the crucial epistemological differences between the practice of medicine and psychiatry, showing that the latter is enacted at the level of language and communication. Consequently, the structures of psychiatric objects, namely, mental disorders and mental symptoms, are complexes of meaning derived from heterogeneous sources - both organic and semantic. Conceptual analysis of such structures is essential as ultimately the validity of empirical research is directly dependent on the conceptual clarification of its objects of inquiry. PMID:27463619

  12. Conceptual design of integrated safeguards systems

    International Nuclear Information System (INIS)

    The Los Alamos Scientific Laboratory (LASL) is currently involved in the conceptual design of safeguards for generic facilities in the back-end of the nuclear fuel cycle (spent-fuel reprocessing, plutonium nitrate-to-oxide conversion, mixed-oxide fuel fabrication, plutonium scrap recovery, and waste handling). These studies are first steps aimed at eventually providing detailed designs of integrated safeguards systems to guide safeguards-related facility construction and/or modification. The purpose of this presentation is to describe the conceptual design process in terms of its definition, a systematic procedure for its implementation, some of the tools required, and an example of the results of a conceptual design. The value of conceptual design and its relationship to other facets of the complete facility design process are also discussed

    This source-term summary document is intended to describe the current understanding of contaminant source terms and the conceptual model for potential source-term release to the environment at the Idaho National Engineering and Environmental Laboratory (INEEL), as presented in published INEEL reports. The document presents a generalized conceptual model of the sources of contamination and describes the general categories of source terms, primary waste forms, and factors that affect the release of contaminants from the waste form into the vadose zone and Snake River Plain Aquifer. Where the information has previously been published and is readily available, summaries of the inventory of contaminants are also included. Uncertainties that affect the estimation of the source term release are also discussed where they have been identified by the Source Term Technical Advisory Group. Areas in which additional information are needed (i.e., research needs) are also identified.

  16. What factors have influenced implementation of the Developmental Approaches in Science, Health and Technology program at two elementary schools on O'ahu, Hawai'i?

    Science.gov (United States)

    Carson, Lani L.

    This dissertation is a report of two hypothesis-generating qualitative case studies that investigated the factors that affected the successful school-wide implementation of the Developmental Approaches in Science, Health and Technology program, a spiraling, integrated, hands-on program for grades Kindergarten to 6 at two public elementary schools on the island of Oahu, in the state of Hawaii. Four key people were interviewed, 47 classrooms were observed three times each, and 41 of 48 teacher surveys were completed. An author-generated flow-of-influences conceptual framework based on other research findings about variables influencing the implementation of a curricular innovation delineates curricular, organizational, and external variables along with possible teacher-perceived outcomes. The results include 42 tables and 44 figures showing the many factors' positive and negative impacts on the schools' reform efforts. Eighteen hypotheses were generated. Well-planned implementations, strong administrative support and leadership, sustained follow-up support, and frequent collegial planning and sharing times seemed to have the greatest positive influences upon teacher confidence regarding program knowledge and sustained program use. More tenured teachers were using the program at levels equal to or greater than newer teachers until around twenty years of teaching experience, when there was a marked decline in program use.

    2011-01-01

    In 1980 Leon Lederman started Saturday Morning Physics with a handful of volunteer physicists, around 300 students and all the physics teachers who tagged along. Today Fermilab offers over 30 programs annually with help from 250 staff volunteers and 50 educators, and serves around 40,000 students and 2,500 teachers. Find out why we bother. Over the years we have learned to take advantage of opportunities and confront challenges to offer effective programs for teachers and students alike. We offer research experiences for secondary school teachers and high school students. We collaborate with educators to design and run programs that meet their needs and interests. Popular school programs include classroom presentations, experience-based field trips, and high school tours. Through our work in QuarkNet and I2U2, we make real particle physics data available to high school students in datadriven activities as well as masterclasses and e-Labs. Our professional development activities include a Teacher Resource Cent...

  2. High energy physics program at Texas A ampersand M University

    International Nuclear Information System (INIS)

    The Texas A ampersand M high energy physics program has achieved significant mile-stones in each of its research initiatives. We are participating in two major operating experiments, CDF and MACRO; the development of two new detector technologies, liquid scintillating fiber calorimetry and knife-edge chambers; and two SSC detector proposals, SDC and TEXAS/EMPACT. We have developed prototypes of a liquid-scintillator fiber calorimeter system, in which internally reflecting channels are imbedded in a lead matrix and filled with liquid scintillator. This approach combines the performance features of fiber calorimetry and the radiation hardness of liquid scintillator, and is being developed for forward calorimetry in TEXAS/EMPACT. A new element in this program is the inclusion of a theoretical high energy physics research program being carried out by D. Nanopoulos and C. Pope. D. Nanopoulos has succeeded in building a string-derived model that unifies all known interactions: flipped SU(5), which is the leading candidate for a TOE. The impact of this work on string phenomenology certainly has far reaching consequences. C. Pope is currently working on some generalizations of the symmetries of string theory, known as W algebras. These are expected to have applications in two- dimensional conformal field theory, two-dimensional extensions of gravity and topological gravity, and W-string theory. The following report presents details of the accomplishments of the Texas A ampersand M program over the past year and the proposed plan of research for the coming year

    2014-10-01

    Resumption of transient testing at the TREAT facility was approved in February 2014 to meet U.S. Department of Energy (DOE) objectives. The National Nuclear Security Administration’s Global Threat Reduction Initiative Convert Program is evaluating conversion of TREAT from its existing highly enriched uranium (HEU) core to a new core containing low enriched uranium (LEU). This paper describes briefly the initial pre-conceptual designs screening decisions with more detailed discussions on current feasibility, qualification and fabrication approaches. Feasible fabrication will be shown for a LEU fuel element assembly that can meet TREAT design, performance, and safety requirements. The statement of feasibility recognizes that further development, analysis, and testing must be completed to refine the conceptual design. Engineering challenges such as cladding oxidation, high temperature material properties, and fuel block fabrication along with neutronics performance, will be highlighted. Preliminary engineering and supply chain evaluation provided confidence that the conceptual designs can be achieved.

  5. Waste Handling Building Conceptual Study

    International Nuclear Information System (INIS)

    The objective of the ''Waste Handling Building Conceptual Study'' is to develop proposed design requirements for the repository Waste Handling System in sufficient detail to allow the surface facility design to proceed to the License Application effort if the proposed requirements are approved by DOE. Proposed requirements were developed to further refine waste handling facility performance characteristics and design constraints with an emphasis on supporting modular construction, minimizing fuel inventory, and optimizing facility maintainability and dry handling operations. To meet this objective, this study attempts to provide an alternative design to the Site Recommendation design that is flexible, simple, reliable, and can be constructed in phases. The design concept will be input to the ''Modular Design/Construction and Operation Options Report'', which will address the overall program objectives and direction, including options and issues associated with transportation, the subsurface facility, and Total System Life Cycle Cost. This study (herein) is limited to the Waste Handling System and associated fuel staging system

    The Graduate K-12 (GK12) program has been developed by NSF to support the national effort to advance scientific knowledge through educational partnerships. This paper highlights research conducted during the 2006-2007 school year with the Texas A&M University GK12 project. Two elementary schools with very high numbers of at risk students - those who are poor, speak English as their second language, and have a history of failing state-mandated tests were identified to be the field site for the GK12 project. In these two, high-minority (97% and 40% African American and Hispanic) schools, 80% and 56% of the children have been identified by the state as at risk; 94% and 52% are classified as economically disadvantaged; and 46% and 2% are limited English proficient, respectively. In the past year, 30% and 73% of fifth grade students in these schools passed the science portion of the Texas Assessment of Knowledge and Skills (TAKS) test. Data collected during a three- week period where GK12 fellows taught the fifth graders Earth science-related topics is presented. During the implementation, students were engaged in technology-, inquiry-, and game-based activities.

    International Nuclear Information System (INIS)

    The principal aim of bioassay monitoring program in Uranium Concentrate Unity, URA, in Caetite is the maintenance of acceptably safe and satisfactory working conditions, according to national and international norms. Specifically, the objective is to interpret measurements in terms of intake of uranium and committed effective dose, so that the results can be used to demonstrate compliance with the system of dose limitation and, mainly, the optimization of radiation protection. The employed technique is the measurement of uranium in excreta from workers in mine, crushing and uranium concentrate production areas. In conclusion, workers from mining and crushing areas should be monitored by the routine program; urine and feces samples should be analyzed by mass spectrometry, with ICP-MS. The operational monitoring program should be carried out in workers from uranium concentrate production area; urine and feces samples should be analyzed by less expensive techniques. (author)

    Full Text Available Tulane University School of Public Health and Tropical Medicine (SPHTM launched the Bachelors of Science in Public Health (BSPH in 2005. The BSPH has steadily grown and comprises one third of the total enrollment in the school. A review of the organizational structure demonstrates that direct responsibility for undergraduate education by a school of public health is advantageous to the success of the program. The competency and skills-based curriculum attracts students. Outcome measures show the enrollment is steadily increasing. The majority of the BSPH graduates continue onto competitive graduate and professional degree programs. Those who seek jobs find employment related to their public health education, but outside of the traditional governmental public health agencies. The combined BSPH/MPH degree is a pipeline for students to pursue a MPH and increases the likelihood students will pursue careers in public health. The range and depth of study in the bachelors program is continually examined. Topics once within the purview of graduate education are now being incorporated into undergraduate courses. Undergraduate public health is one of a number of factors that is influencing changes in the MPH degree.

    We present here ail approach to conceptual querying where the aim is, given a collection of textual database objects or documents, to target an abstraction of the entire database content in terms of the concepts appearing in documents, rather than the documents in the collection. The approach...... is motivated by an obvious need for users to survey huge volumes of objects in query answers. An ontology formalism and a special notion of-instantiated ontology" are introduced. The latter is a structure reflecting the content in the document collection in that; it is a restriction of a general world...... knowledge ontology to the concepts instantiated in the collection. The notion of ontology-based similarity is briefly described, language constructs for direct navigation and retrieval of concepts in the ontology are discussed and approaches to conceptual summarization are presented....

    DeMott, Diana; Fuqua, Bryan; Wilson, Paul

    2013-01-01

    Once a project obtains approval, decision makers have to consider a variety of alternative paths for completing the project and meeting the project objectives. How decisions are made involves a variety of elements including: cost, experience, current technology, ideologies, politics, future needs and desires, capabilities, manpower, timing, available information, and for many ventures management needs to assess the elements of risk versus reward. The use of high level Probabilistic Risk Assessment (PRA) Models during conceptual design phases provides management with additional information during the decision making process regarding the risk potential for proposed operations and design prototypes. The methodology can be used as a tool to: 1) allow trade studies to compare alternatives based on risk, 2) determine which elements (equipment, process or operational parameters) drives the risk, and 3) provide information to mitigate or eliminate risks early in the conceptual design to lower costs. Creating system models using conceptual design proposals and generic key systems based on what is known today can provide an understanding of the magnitudes of proposed systems and operational risks and facilitates trade study comparisons early in the decision making process. Identifying the "best" way to achieve the desired results is difficult, and generally occurs based on limited information. PRA provides a tool for decision makers to explore how some decisions will affect risk before the project is committed to that path, which can ultimately save time and money.

The major themes of this book are the seven concepts of planning, circulation, 3D, construction, materials, colour and lighting, which covers the entire spectrum of a designer’s activity. Analysing design concepts from the view of the range of possibilities that the designer can examine and eventually decide by choice and conclusive belief the appropriate course of action to take in forming that particular concept, the formation and implementation of these concepts is taken in this book to aid the designer in his/her professional task of completing a design proposal to the client. The purpose of this book is to prepare designers to focus on each concept independently as much as possible, whilst acknowledging relative connections without unwarranted influences unfairly dictating a conceptual bias, and is about that part of the design process called conceptual analysis.

    Full Text Available Abstract InSite is North Americas first supervised injection site and a landmark public heath initiative operating in Vancouver since 2003. The program is a vital component of that cities internationally recognized harm reduction approach to its serious problems with drugs, crime, homelessness and AIDS. InSite currently operates under a waiver of Federal rules that allow it to provide services as a research project. An extensive evaluation has produced very positive results for thousands of users. Normally such strong evidence documenting the successes of such a program, and the medical and public health significance of these positive outcomes, would be the basis for celebration and moves to expand the model and provide similar services elsewhere in Canada. Instead, there is a distinct possibility that InSite will be closed by the newly elected Canadian Prime Minister Paul Harper – a conservative who has traveled to the US to visit George WQ Bush and come back antagonistic to harm reduction in all its forms. Because InSites federal waiver is expiring and up for renewal in September, the fear is that Mr. Harpers will not renew the approval and that the program will be forced to close down. The risks associated with the potential closure of InSite need to be fully understood. This editorial lays out these public health risks and the associated economic impact if InSite were to be closed. In addition to preventable deaths and disease, InSites closure will cost Vancouver and British Columbia between $3.8 and $ 8.8 million in preventable health care expenses over the next two years.

    2012-04-01

    Full Text Available The purpose of this study was to investigate how the use of the computer simulations program VPython facilitated students’ conceptual understanding of fundamental physical principles and in constructing new knowledge of physics. We focused on students in a calculus-based introductory physics course, based on the Matter and Interactions curriculum of Chabay & Sherwood (2002 at a large state engineering and science university in the USA. A major emphasis of this course was on computer modeling by using VPython to write pro¬grams simulating physical systems. We conducted multiple student interviews, as well as an open-ended exit survey, to find out student views on how creating their own simulations to enhanced-conceptual understanding of physics and in constructing new knowledge of phys¬ics. The results varied in relation to the phases when the interviews were conducted. At the beginning of the course, students viewed the simulation program as a burden. However, dur¬ing the course, students stated that it promoted their knowledge and better conceptual understanding of physical phenomena. We deduce that VPython computer simulations can improve students’ conceptual understanding of fundamental physical concepts and promote construction of new knowledge in physics, once they overcome the initial learning curve associated with the VPython software package.

  14. A Metric Conceptual Space Algebra

    Science.gov (United States)

    Adams, Benjamin; Raubal, Martin

    The modeling of concepts from a cognitive perspective is important for designing spatial information systems that interoperate with human users. Concept representations that are built using geometric and topological conceptual space structures are well suited for semantic similarity and concept combination operations. In addition, concepts that are more closely grounded in the physical world, such as many spatial concepts, have a natural fit with the geometric structure of conceptual spaces. Despite these apparent advantages, conceptual spaces are underutilized because existing formalizations of conceptual space theory have focused on individual aspects of the theory rather than the creation of a comprehensive algebra. In this paper we present a metric conceptual space algebra that is designed to facilitate the creation of conceptual space knowledge bases and inferencing systems. Conceptual regions are represented as convex polytopes and context is built in as a fundamental element. We demonstrate the applicability of the algebra to spatial information systems with a proof-of-concept application.

  19. Conceptual design summary

    International Nuclear Information System (INIS)

    The Advanced Neutron Source (ANS) is a new basic and applied research facility based on a powerful steady-state research reactor that provides beams of neutrons for measurements and experiments in the fields of materials science and engineering, biology, chemistry, materials analysis, and nuclear science. The useful neutron flux for these experiments will be at least five times, and in some cases twenty times, more than is available at the world's best existing facilities. In addition, ANS will provide irradiation capabilities for the production of radioisotopes for medical applications, research, and industry and facilities for materials irradiation testing. The need for a new steady-state neutron research facility in the United States was emphasized by the 1984 National Academy Report and confirmed by the Department of Energy's (DOE's) Energy Research Advisory Board in 1985. These studies defined a minimum thermal neutron flux requirement of 5 x 1019 m-2 · s-1. The National Steering Committee for an Advanced Neutron Source, with representation from the major fields of science that will use the facility, was established in 1986 and has continued to define the performance requirements and instrument layouts needed by the user community. To minimize technical risks and safety issues, the project adopted a policy of not relying upon new inventions to meet the minimum performance criteria, and the design presented in this report is built on technologies already used in other facilities and development programs: for example, the involute aluminum-clad fuel plates common to HFIR and ILL and the uranium silicide fuel developed in DOE's Reduced Enrichment for Research and Test Reactors program and tested in reactors worldwide. At the same time, every state-of-the-art technique has been implemented to optimize neutron beam delivery at the experiments

    Full Text Available Bangladesh Open University (BOU runs school programs as part of its academic activities through open schooling since its inception. As of today, the Open School uses the first generation self-learning materials (SLMs written, before an era, following an in-house style and template. The concerned faculty member corrects, every year, texts before the reprint; but this is limited to spelling mistakes, factual errors and page make-ups only. The University has taken policy and steps to revise the texts as a whole which is still limited to the previous process. But; the current government is implementing the agenda of digital Bangladesh which definitely will influence the texts vis-à-vis template, learner’s instructions, gender-sensitiveness, context and content. In addition, education theory has been sifted from instructivism to constructivism which is being experimented and implemented by the Ministerial project entitled Teaching Quality Improvement (TQI partnering with the BOU School of Education with new texts. Time changes, new things are being adopted. Open School also requires revising its texts in relation to the government’s current agenda of implementing the digital Bangladesh. This study collects data from tutors, distance educators, writers and reviewers and finally develops a framework for revising the OS SLMs at a digital environment.

    The development of successful urban tree plantings has at least four critical components: 1) expectations and goals appropriate for cities, 2) an analysis of site-specific environmental conditions, 3) selection of taxa responsive to that set of site conditions and 4) a regular program of management. The issues involved that are both conceptual (such as our attitudes towards trees) and technical (such as the size of a planting space or the level of summer irrigation).

  5. Gamma scanner conceptual design report

    International Nuclear Information System (INIS)

    The Fuels and Materials Examination Facility (FMEF) will include several stations for the nondestructive examination of irradiated fuels. One of these stations will be the gamma scanner which will be employed to detect gamma radiation from the irradiated fuel pins. The conceptual design of the gamma scan station is described. The gamma scanner will use a Standard Exam Stage (SES) as a positioner and transport mechanism for the fuel pins which it will obtain from a magazine. A pin guide mechanism mounted on the face of the collimator will assure that the fuel pins remain in front of the collimator during scanning. The collimator has remotely adjustable tungsten slits and can be manually rotated to align the slit at various angles. A shielded detector cart located in the operating corridor holds an intrinsic germanium detector and associated sodium-iodide anticoincidence detector. The electronics associated with the counting system consist of standard NIM modules to process the detector signals and a stand-alone multichannel analyzer (MCA) for counting data accumulation. Data from the MCA are bussed to the station computer for analysis and storage on magnetic tape. The station computer controls the collimator, the MCA, a source positioner and the SES through CAMAC-based interface hardware. Most of the electronic hardware is commercially available but some interfaces will require development. Conceptual drawings are included for mechanical hardware that must be designed and fabricated

    Silberman, Donn M.; Doushkina, Valentina V.

    2010-08-01

    Three years ago we reported on a new optics education program established at the Irvine Center for Applied Competitive Technologies (CACT) at the Advanced Technology and Education Park (ATEP) operated by the South Orange County Community College District (SOCCCD). This paper reports on new Optical Engineering and Instrument Design Programs now being offered through the University of California, Irvine Extension. While there are some similarities between the two programs, the differences are mainly the students' level. The community college level programs were targeted primarily at technicians and junior level engineers. The university level programs are targeted at senior level engineering and physical sciences university students, graduate and post graduate students and designers in industry. This paper reviews the reasons for establishing these certificate programs and their content, the students' motivations for taking them and their employers' incentives for encouraging the students.

  7. How effective are programs at managing transition from hospital to home? A case study of the Australian transition care program

    Directory of Open Access Journals (Sweden)

    Gray Leonard C

    2012-03-01

    Full Text Available Abstract Background An increasing demand for acute care services due in part to rising proportions of older people and increasing rates of chronic diseases has led to new models of post-acute care for older people that offer coordinated discharge, ongoing support and often a focus on functional restoration. Overall, review of the literature suggests there is considerable uncertainty around the effectiveness and resource implications of the various model configurations and delivery approaches. In this paper, we review the current evidence on the efficacy of such programs, using the Australian Transition Care Program as a case study. Discussion The Australian Transition Care Program was established at the interface of the acute and aged care sectors with particular emphasis on transitions between acute and community care. The program is intended to enable a significant proportion of care recipients to return home, rather than prematurely enter residential aged care, optimize their functional capacity, and reduce inappropriate extended lengths of hospital stay for older people. Broadly, the model is configured and targeted in accordance with programs reported in the international literature to be effective. Early evaluations suggest good acceptance of the program by hospitals, patients and staff. Ultimately, however, the program's place in the array of post-acute services should be determined by its demonstrated efficacy relative to other services which cater for similar patient groups. Summary Currently there is a lack of robust evaluation to provide convincing evidence of efficacy, either from a patient outcome or cost reduction perspective. As the program expands and matures, there will be opportunity to scrutinise the systematic effects, with lessons for both Australian and international policy makers and clinical leaders.

  10. Detection Of Control Flow Errors In Parallel Programs At Compile Time

    Directory of Open Access Journals (Sweden)

    Bruce P. Lester

    2010-12-01

    Full Text Available This paper describes a general technique to identify control flow errors in parallel programs, which can be automated into a compiler. The compiler builds a system of linear equations that describes the global control flow of the whole program. Solving these equations using standard techniques of linear algebra can locate a wide range of control flow bugs at compile time. This paper also describes an implementation of this control flow analysis technique in a prototype compiler for a well-known parallel programming language. In contrast to previous research in automated parallel program analysis, our technique is efficient for large programs, and does not limit the range of language features.

  12. The program of the ALARA Center at Brookhaven National Laboratory

    International Nuclear Information System (INIS)

    In 1984 the Brookhaven National Laboratory was asked by the Nuclear Regulatory Commission to set up a Center to monitor dose-reduction efforts in the US and abroad and to focus the industry's attention on ALARA. The paper summarizes the main work of the ALARA Center between 1984 and 1992. The Center maintains nine data bases for the NRC and the Nuclear Power Industry. These databases are constantly updated and access to them is provided through a personal computer and a modem and by periodic publications in the form of a newsletter and NUREG reports. Also described briefly are eight other projects related to dose-reduction at nuclear power plants that the Center has carried out for the NRC. Among these are projects that analyze the cost-effectiveness of engineering modifications, look at worldwide activities at dose reduction and compare US and foreign dose experience, examine high-dose worker groups and high-dose jobs, develop optimum techniques to control contamination at nuclear plants, and look at the doses being received by men and women in all sectors of the nuclear industry

  13. Program of energy saving measures at NIKHEF-MEA

    International Nuclear Information System (INIS)

    In this report a package of energy-saving measures for NIKHEF-MEA are presented. The proposed measures have reference to the raising, in relatively short time, of the modulation frequency to the desired value when, in behalf of maintenance or tuning the repetition frequency is set low. A second group of measures consists in the limitation of the energy consumption of the cooling systems at MEA and AFBU. At MEA important economizations can be achieved by the limitation of the heat-leaching to outside when the accelerator is out of operation while at AFBU the tuning of the r.p.m. of the circulation pumps in the cooling systems seems to be attractive. As least measure of the package the power control of NIKHEF is incorporated. This should allow for exploiting the available power as economical as possible and for keeping the costs for electricity supply as low as possible. 4 tabs

    OBJECTIVE To compare vocational aspirations and outcomes of participants in the 10-week Leadership Program for Veterinary Students at Cornell University. DESIGN Survey. SAMPLE Veterinary students who participated in the program between 1990 and 2013. PROCEDURES Questionnaires that sought information about the career aspirations of participants at the beginning and end of the program were reviewed, along with records documenting the career progression of participants, audio recordings of interviews conducted with students, and notes of vocation-oriented counseling sessions held during each year's program. RESULTS At the conclusion of the program, 143 of 174 (82%) participants indicated they were more likely than not to undertake research training after completing their veterinary degree, compared with 106 of 174 (61%) at the beginning. Participation also stimulated interest in residency training and industry, but did little to promote interest in careers in government or the military. The percentage of participants who indicated they were more likely than not to pursue additional training in private practice decreased from 97 of 174 (56%) at the beginning of the program to 75 of 174 (43%) at the end. Information on career progression was available for 391 individuals, of whom 177 (45%) were pursuing careers of the kind envisioned by the program. However, 189 (48%) participants had a career in general or specialty clinical practice. CONCLUSIONS AND CLINICAL RELEVANCE The Leadership Program appeared to have a short-term influence on careers anticipated by program participants. However, a substantial proportion pursued careers in clinical practice after graduation. PMID:27654162

  1. Conceptual Drivers for an Exploration Medical System

    Science.gov (United States)

    Antonsen, E.; Canga, M.

    2016-01-01

    Interplanetary spaceflight provides unique challenges that have not been encountered in prior spaceflight experience. Extended distance and timeframes introduce new challenges such as an inability to resupply medications and consumables, inability to evacuate injured or ill crew, and communication delays that introduce a requirement for some level of autonomous medical capability. Because of these challenges the approaches used in prior programs have limited application to a proposed three year Mars mission. This paper proposes a paradigm shift in the approach to medical risk mitigation for crew health and mission objectives threatened by inadequate medical capabilities in the setting of severely limited resources. A conceptual approach is outlined to derive medical system and vehicle needs from an integrated vision of how medical care will be provided within this new paradigm. Using NASA Design Reference Missions this process assesses each mission phase to deconstruct medical needs at any point during a mission. Two operational categories are proposed, nominal operations (pre-planned activities) and contingency operations (medical conditions requiring evaluation) that meld clinical needs and research needs into a single system. These definitions are used to derive a task level analysis to support quantifiable studies into a medical capabilities trade. This trade allows system design to proceed from both a mission centric and ethics-based approach to medical limitations in an exploration class mission.

    We review Theodore Millon's contributions to conceptualizing personality disorders in contemporary clinical science and practice. Millon worked tirelessly across professional domains and theoretical orientations, developing a rich integrative theory of personality and its pathology, directly and indirectly impacting the evolving iterations of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III through DSM-5), and advocating for the personality disorders through his contributions to cofounding the International Society for the Study of Personality Disorders and the Journal of Personality Disorders. We conclude with a closer look at Millon's final major contributions to conceptualizing personality disorders as well as the strengths and limitations of his approach.

  11. 3He Neutron Spin Filter cell development program at JCNS

    International Nuclear Information System (INIS)

    In order to produce high-quality 3He Neutron Spin Filters (NSF) with a high polarisation level, it is necessary to achieve a long 3He relaxation time by the reduction of the wall relaxation. This requires one to minimise the amount of impurities at the surface of the glass cells, and to have as few contaminants as possible in the gas filling system. In this report we describe the detailed procedure we employ to produce 3He cells using our newly built filling station. The obtained life times for a number of cells are practically approaching the fundamental limit imposed by the dipole-dipole interaction between 3He atoms.

  14. Spintronics: Conceptual Building Blocks

    Science.gov (United States)

    Ansermet, J.-Ph.

    The purpose of this introduction to spintronics is to provide some elementary description of its conceptual building blocks. Thus, it is intended for a newcomer to the field. After recalling rudimentary descriptions of spin precession and spin relaxation, spin-dependent transport is treated within the Boltzmann formalism. This suffices to introduce key notions such as the spin asymmetry of the conductivities in the two-current model, the spin diffusion length, and spin accumulation. Two basic mechanisms of spin relaxation are then presented, one arising from spin-orbit scattering and the other from electron-magnon collisions. Finally, the action of a spin-polarized current on magnetization is presented in a thermodynamics framework. This introduces the notion of spin torque and the characteristic length scale over which the transverse spin polarization of conduction electron decays as it is injected into a magnet.

    Bækgaard, Lars

    1998-01-01

    We analyze some of the problems related to conceptual modeling in data warehousing environments. The long-term data warehousing challenge is flexibility rather than efficiency. The reason is that most warehouses will contain growing collections of historical data that are supposed to satisfy...... changing information needs. We show how the event-entity-relationship model (EVER) can be used for schema design and query formulation in data warehouses. Our work is based on a layered data warehouse architecture in which a global data warehouse is used for flexible long-term organization and storage...... of all warehouse data whereas local data warehouses are used for efficient query formulation and answering. In order to support flexible modeling of global warehouses we use a flexible version of EVER for global schema design. In order to support efficient query formulation in local data warehouses we...

  17. Materials evaluation programs at the Defense Waste Processing Facility

    International Nuclear Information System (INIS)

    The Savannah River Site (SRS) has been operating a nuclear fuel cycle since the 1950s to produce nuclear materials in support of the national defense effort. About 83 million gallons of high-level waste produced since operations began has been consolidated by evaporation into 33 million gallons at the waste tank farm. The Department of Energy authorized the construction of the Defense Waste Processing Facility (DWPF), the function of which is to immobilize the waste as a durable borosilicate glass contained in stainless steel canisters prior to the placement of the canisters in a federal repository. The DWPF is now mechanically complete and is undergoing commissioning and run-in activities. A brief description of the DWPF process is provided

  18. Greater confinement disposal program at the Savannah River Plant

    International Nuclear Information System (INIS)

    The first facility to demonstrate Greater Confinement Disposal (GCD) in a humid environment in the United States has been built and is operating at the Savannah River Plant. GCD practices of waste segregation, packaging, emplacement below the root zone, and waste stabilization are being used in the demonstration. Activity concentrations to select wastes for GCD are based on a study of SRP burial records, and are equal to or less than those for Class B waste in 10CFR61. The first disposal units to be constructed are 9-foot diameter, thirty-foot deep boreholes which will be used to dispose of wastes from production reactors, tritiated wastes, and selected wastes from off-site. In 1984 an engineered GCD trench will be constructed for disposal of boxed wastes and large bulky items. 2 figures, 1 table

    2001-12-01

    The Jyväskylä K130 cyclotron has been modified to allow also negative ion acceleration with stripping extraction. A multi-cusp ion source for negative ions (H- and d-) was built [1]. The source gives over 5 mA at a voltage of 5.9 kV, which is used for 30 MeV protons. The extracted 30 MeV proton beam of 60 μA from the cyclotron has been reached. Due to very good extraction efficiency the dose rate in the cyclotron vault has decreased by a factor of 10-20 with 30 MeV protons compared to positive ion extraction. Also the inflector change was automated in order to reduce the dose for personnel.

  1. Training programs for emergency response personnel at Hanford

    International Nuclear Information System (INIS)

    The Three Mile Island reactor accident has focused attention on emergency planning and preparedness including selection and training of personnel. At Hanford, Pacific Northwest Laboratory (PNL) is in the unique position of providing emergency response personnel, planning, training and equipment not only for its own organization and facilities but also for the Hanford Site in general, as well as the Interagency Radiological Assistance Plan (IRAP) Region 8 Team. Team members are chosen for one or more of the emergency teams based upon professional education and/or experience as well as interest, aptitude and specialized knowledge. Consequently, the initial training orientation of each new team member is not directed toward general professional ability, but rather toward specialized knowledge required to carry out their assigned emergency tasks. Continual training and practice is necessary to maintain the interest and skills for effectively coping with major emergencies. The types of training which are conducted include: tests of emergency systems and/or procedures; drills involving plant employees and/or emergency team members (e.g., activation of emergency notification systems); short training sessions on special topics; and realistic emergency exercises involving the simulation of major accidents wherein the emergency team must solve specific problems on a real time basis

    The Design Demonstration Experiment for the University of Missouri Research Reactor (DDE-MURR) is intended to facilitate Low Enriched Uranium (LEU) conversion of the MURR by demonstrating the performance and fabrication of the LEU fuel element design through an irradiation test in a 200mm channel at the Belgium Reactor 2 (BR2). Revision 0 of this report was prepared at the end of government fiscal year 2012 when most of the resources for furthering DDE design work were expected to be postponed. Hence, the conceptual design efforts were summarized to provide the status of key objectives, notable results, and provisions for future design work. Revision 1 of this report was prepared at the end of fiscal year 2013 in order to include results from a neutronic study performed by BR2, to incorporate further details that had been achieved in the engineering sketches of the irradiation devices, and to provide an update of the DDE-MURR campaign in relation to program objectives and opportunities for its eventual irradiation. These updates were purposed to bring the DDE-MURR conceptual design to level of maturity similar to that of the other two DDE efforts (DDE-MITR and DDE-NBSR). This report demonstrates that the DDE-MURR design effort is well on the path to producing a suitable irradiation experiment, but also puts forth several recommendations in order to facilitate success of the irradiation campaign.

    2000-11-06

    The objective of the ''Waste Handling Building Conceptual Study'' is to develop proposed design requirements for the repository Waste Handling System in sufficient detail to allow the surface facility design to proceed to the License Application effort if the proposed requirements are approved by DOE. Proposed requirements were developed to further refine waste handling facility performance characteristics and design constraints with an emphasis on supporting modular construction, minimizing fuel inventory, and optimizing facility maintainability and dry handling operations. To meet this objective, this study attempts to provide an alternative design to the Site Recommendation design that is flexible, simple, reliable, and can be constructed in phases. The design concept will be input to the ''Modular Design/Construction and Operation Options Report'', which will address the overall program objectives and direction, including options and issues associated with transportation, the subsurface facility, and Total System Life Cycle Cost. This study (herein) is limited to the Waste Handling System and associated fuel staging system.

    2016-01-01

    Evidence suggests that diabetes education can be delivered at the worksite to better support employees' diabetes self-management and improve productivity and health care costs. This study was conducted to address the feasibility of a diabetes worksite education program for employees at a large urban academic health care institution. The diabetes education program was delivered in the diabetes center at the institution, a resource that was previously underutilized by employees. Through collaboration with groups in the institution, 20 employees of diverse ethnicity participated in the worksite diabetes education program with positive outcomes: improved glycemic control measured (HbA1c), attainment of self-management goals, and satisfaction with the program. Work absences trended downward, but numbers of hospitalizations and emergency department visits were unchanged in the 3 months following education. Recommendations include replication of the study with more employee participation and program evaluation over a longer period of time to continue assessment of employees' educational needs.
