    The UNEP (United Nations Environment Program) discussed the environmental impacts of extraction, transportation, and utilization of fossil fuels at a meeting in Warsaw, the first in a series of UNEP undertakings, to be followed by studies on nuclear energy and renewable energy sources. The major issues examined at the meeting were human health effects of atmospheric emissions, especially SO/sub 2/; effects of SO/sub 2/ on vegetation and bodies of fresh water; long-term ecologic effects of oil spills in the sea; and potential effects on climate from atmospheric CO/sub 2/ arising from fossil fuel combustion. A doubling of the atmospheric CO/sub 2/ concentration would cause an estimated 1.5/sup 0/-3.0/sup 0/C increase in the surface air temperature. With an amount of CO/sub 2/ equivalent to 0.5 x 10/sup 10/ tonnes of carbon annually injected into the atmosphere from fossil fuels, of which only 0.27 x 10/sup 10/ tonnes are removed by some exchange processes with ocean or land. A 17% increase in atmospheric CO/sub 2/ over the 1976 concentration of 332 ppm is expected by the year 2000.

    1997-01-01

    Integrated assessments in support of environmental policy have been applied to a number of countries and regions, and to international negotiations. UNEP's first Global Environment Outlook (GEO-1) can be seen as a step towards making the tool of integrated assessment more widely available as a means for focusing action. This technical report documents RIVM's contribution to the GEO-1 report, focusing on the subject 'looking ahead'. It is illustrated that a 'what if' analysis helps to look beyond the delays in environmental and resource processes. This report illustrates that integrated assessment and modelling techniques can be excellent tools for environment and development policy-setting. The methodology, however, will need to be further developed and adapted to the realities and expectations of diverse regions, incorporating alternative policy strategies and development scenarios. This report focuses primarily on the period 1970-2015, because reliable historical data are often only generally available from 1970 onwards and the year 2015 is believed to match the time perspective of decision-makers. The findings of the analysis are reported in terms of six regions, corresponding with the division of the UNEP regional offices. Questions asked are: how will socioeconomic driving forces affect freshwater and land resources, and how will these changes mutually interact, and why are these changes important for society? Chapter 2 deals with the development of the social and economic driving forces. In the Chapters 3 and 4 it is discussed how this pressure influences selected aspects of the environment. Chapter 3 alone addresses the importance of selected elements of the interacting global element cycles for environmental quality, while Chapter 4 addresses land resources, their potential for food production and associated dependence on freshwater resources. The impacts on selected components of natural areas (Chapter 5) and society (Chapter 6) are subsequently addressed

    2003-01-01

    The third Global Environment Outlook (GEO-3) was published on the eve of the Johannesburg summit (autumn 2002). GEO-3 looked back thirty years and forward thirty years. A set of what-if scenarios was used to explore the ways our society can advance, including implications for environmental and social goals. Characteristically, GEO-3 examines in a relatively deep fashion how its global scenarios can be interpreted in the context of each of the world's regions. This brochure presents the pan-European elaboration of the four GEO-3 scenarios. It focusses on the scenarios proper and their impacts in environmental terms. The scenarios are: The Markets First scenario envisages a world in which market-driven developments converge on the currently prevailing values and expectations in industrialized countries; In a Policy First world, strong actions are undertaken by governments in an attempt to achieve specific social and environmental goals; The Security First scenario assumes a world full of large disparities, where inequality and conflict, brought about by socio-economic and environmental stresses, prevail: and Sustainability First pictures a world in which a new development paradigm emerges in response to the challenge of sustainability supported by new, more equitable values and institutions. The second section describes 'the pan-European tale of the four futures' in a predominantly qualitative manner. Section 3 presents a regionally differentiated examination of the environmental implications of the scenarios. Details on input material, assumptions and methodologies applied, and actual results, can be found in Chapter 4 of GEO-3 'Outlook 2002-32' and in the Technical Background Report on GEO-3 Scenario Work

    1982-04-01

    The 1972 United Nations Conference on the Human Environment (Stockholm) outlined a ''master plan'' for protecting the world's environment which linked environmental assessment, environmental management, and supporting measures, as basic and inseparable elements - also recognizing the advantages of a regional approach in contributing to the solution of global problems. The development of UNEP's Regional Seas Programme, since the Action Plan for the Mediterranean was adopted in 1975, demonstrates that the basic concepts formulated at Stockholm can effectively foster regional cooperation among interested States, and that such cooperation can and does benefit greatly from the support of the United Nations as a whole. The viability of any long-term regional programme lies with the political and financial commitment of the Governments concerned. Within the UNEP Regional Seas Programme this commitment is usually formalized through binding regional legal agreements, and is manifested concretely through an agreed set of activities that are revised periodically by the Governments involved. It is expected that these activities will be adquately supported by financial resources put at the disposal of each of the regional programmes primarily by the Governments concerned.

    1988-01-01

    The Second Workshop of Participants in the Joint FAO-IOC-WHO-IAEA-UNEP Project on Monitoring of Pollution in the Marine Environment of the West and Central African Region (WACAF/2) was attended by 29 participants from 10 countries (Senegal, The Gambia, Sierra Leone, Cote d'Ivoire, Ghana, Benin, Nigeria, Cameroun, Congo and Gabon). Levels of metals, chlorinated hydrocarbons and petroleum components in marine biota were discussed in seven scientific reports which were presented by the participating scientists (Cote d'Ivoire, Sierra Leone, Nigeria, The Gambia, ghana and Cameroun). Three of the presented reports were on organochlorines and four dealt with trace metal levels in marine organisms. The Representative of the International Atomic Energy Agency (IAEA) reviewed the results obtained during the data quality assurance intercalibration exercises carried out in the region during the first phase. The result received are still within acceptable range. However, there seems to be a trend for values to be higher than the range of finally certified concentrations. Considering that most results were clearly better in the second exercise, after equipment service, part of the earlier deviation might be attributed to instrument malfunctions. These results can be regarded as fairly encouraging for the future development in the West and Central African marine pollution monitoring programme. Refs, tabs

    The UNEP (United Nations Environment Programme) programme of Greenhouse Gas Abatement Costing Studies is intended to clarify the economic issues involved in assessing the costs of limiting emissions of greenhouse gases and to propose approaches to comparable costing studies. Phase 1 of the Zimbabwe country study describes the current energy situation in Zimbabwe related to the national economy, energy supply and demand and amounts of greenhouse gas emissions. Factors regarding the geography, (including a map illustrating the degree and character of land degradation by erosion) population, politics, international relations, land-use and management of the energy sector are dealt with in detail and the text is illustrated with data compiled from the study. It is estimated that Zimbabwe consumed 270.4 Tj of energy during 1988 and emitted 21.7 tonnes of carbon dioxide. An emission intensity of 80.2 tonnes/Tj for the whole economy and 63.6 tonnes/Tj for electric power generation alone was calculated. Forecasting for the year 2020 estimated carbon dioxide emission intensities of 73.5 tonnes/Tj for the whole economy and 43.7 tonnes for power generation. Net carbon dioxide emissions are predicted to be 30-42 tonnes during 2020. (AB).

    The United Nations 'Conference on Environment and Development' (Rio de Janeiro, June 1992) adopted the 'Agenda 21' action programme. Agenda 21, Chapter 19 'Environmentally Sound Management of Toxic Chemicals including the Prevention of Illegal International Traffic with Toxic and Dangerous Products' includes detailed instructions for activities for the improvement of chemical safety. As described in Programme Area C 'Information Exchange on Toxic Chemicals and Chemical Risks', international institutions responsible for the exchange of information on chemical risks are to be strengthened. The close cooperation between the Federal Environmental Agency and UNEP Chemicals (until 1995 UNEP/IRPTC (United Nations Environment Programme / International Register of Potentially Toxic Chemicals)) on the exchange of scientific and legal information on hazardous chemicals represents a direct and successful contribution to the implementation of Agenda 21, Chapter 19. UNEP Chemicals was supported in the area of data collection. In return, the noted data of UNEP Chemicals, which were elaborated in international cooperation, were made directly available to the Federal Environmental Agency. This cooperation with UNEP Chemicals represents an important contribution to the international exchange of data on hazardous chemicals. (orig.)

    1990-01-01

    Remote manual operations in radiation environments are typically performed very slowly. Sensor-based computer-controlled robots hold great promise for increasing the speed and safety of remote operations; however, the programming of robotic systems has proven to be expensive and difficult. Generalized approaches to robot programming that reuse available software modules and employ programming languages which are independent of the specific robotic and sensory devices being used are needed to speed software development and increase overall system reliability. This paper discusses the robot independent programming environment (RIPE) developed at Sandia National Laboratories (SNL). The RIPE is an object-oriented approach to robot system architectures; it is a software environment that facilitates rapid design and implementation of complex robot systems for diverse applications. An architecture based on hierarchies of distributed multiprocessors provides the computing platform for a layered programming structure that models applications using software objects. These objects are designed to support model-based automated programming of robotic and machining devices, real-time sensor-based control, error handling, and robust communication

  7. Depleted uranium in Kosovo. Post-conflict environmental assessment. UNEP scientific mission to Kosovo, 5-19 November 2000

    International Nuclear Information System (INIS)

    2003-01-01

    This report presents the findings of the first-ever international assessment of the environmental impact of depleted uranium (DU) when used in a real conflict situation. It has been carried out as part of the post-conflict assessments conducted by the United Nations Environment Programme (UNEP) in the Balkans. The report builds on an earlier theoretical study by UNEP. In October 1999, as part of its assessment of the Kosovo conflict's impact on the environment and human settlements, UNEP carried out a Desk Assessment study of the potential effects of the possible use of DU during the conflict. The study was limited by the lack of information on the actual use of DU. In July 2000, however, the North Atlantic Treaty Organization (NATO) provided UNEP with the information required, enabling a field mission to be planned and conducted. The information included a map indicating the location of 112 separate strikes by DU ammunition, and a table showing the number of DU rounds used and the coordinates of the targeted areas. During the field mission to Kosovo, from 5 - 19 November 2000, soil, water and other samples were collected from eleven sites where DU had reportedly been used during the conflict. Five separate laboratories then analysed the samples. When the laboratory phase was finalised in early March, the analyses of the samples collected showed only low levels of radioactivity. Furthermore, the results suggested that there is no immediate cause for concern regarding toxicity. However, major scientific uncertainties persist over the long-term environmental impacts of DU, especially regarding groundwater. Due to these scientific uncertainties, UNEP calls for precaution. There is a very clear need for action to be undertaken on the clean-up and decontamination of the polluted sites, for awareness-raising aimed at the local population, and for future monitoring. Just as the Desk Assessment conducted in October 1999 advised precaution, the recommendations of this

    The project initiated by the United Nations Environment Programme aims to clarify some economic issues involved in greenhouse gas limitation by carrying out comparative studies of various nations. The programme should contribute to the establishment of a consistent methodological framework for making cost assessments of greenhouse gas abatement and help to support countries in the process of establishing national and international agreements on actions to combat climate change. The publication gives a survey of Danish energy demand and supply, emissions and current energy policy issues and reviews existing studies of carbon dioxide reductions. This includes the overall national environmental policy and the plan of action for the transport sector. Conclusions are that there seems to be a long-term potential for significant reduction of CO 2 emission by 10-15% by 2010 with no additional costs, a 50% reduction will cost DKK 25-50 per kg reduced CO 2 . The most promising options include increased use of cogeneration of heat and electricity, and electricity conservation in households, services and in industry. Economic growth is forecast as ca. 2.7% and energy prices for oil products should increase by ca. 4.8%. A 40% reduction of CO 2 emission in the year 2005 would increase costs by 1-2%, and a reduction of two thirds of present emission should be possible at no additional cost compared to the reference cases. There is general agreement that a reduction of carbon dioxide emission of 15-30% by 2005-10 should involve no additional costs to society. (AB) (11 refs.)

    Full text: Vienna/Nairobi - Mohamed ElBaradei, the Director-General of the International Atomic Energy Agency (IAEA) and Klaus Toepfer, Executive Director of the United Nations Environment Programme (UNEP), have agreed to consider ways and means to respond to requests for fact-finding missions to Bosnia-Herzegovina, the Federal Republic of Yugoslavia and Iraq where depleted uranium (DU) was used during military conflicts. The two organizations will co-ordinate their action with the World Health Organization, which has recently decided to send a team to study the health effects of depleted uranium in Iraq, as well as with other relevant UN system organizations. Pekka Haavisto, Chairman of UNEP's Depleted Uranium Assessment Team, is meeting today with UN officials in Sarajevo for consultations on a possible future mission to Bosnia-Herzegovina. Mr. Haavisto will visit Belgrade tomorrow to meet with officials of the Federal Republic of Yugoslavia. The IAEA is considering holding a training course to improve the understanding and skills of specialist staff from concerned countries. The main focus will be on measurement methods and the assessment of risks from depleted uranium and other radioactivity. The possibility of sending fact-finding missions to Bosnia-Herzegovina, the Federal Republic of Yugoslavia and Iraq follows last year's mission to Kosovo by the UNEP-led DU Assessment Team. UNEP will wait for the scientific findings of the report of the Kosovo mission, expected to be released in early March, before it embarks on new DU field assessments. (author)

    1992-01-01

    The first meeting of the Global Task Team on the Implications of Climate Change on Coral Reefs was held to develop an authoritative scientific and technical review of the implications of climate change for coral reefs and their ecologically sustainable use. The Task Team is expected to provide expert advice and guidance in the implementation of the pilot activity on coral reef monitoring as part of the UNEP-IOC-WMO Long-Term Global Monitoring System of coastal and near-shore phenomena related to climate change. This would ensure coordination of various activities aimed at assessing the scale of impacts on natural environments and socio-economic systems particularly in the case of low-lying islands and other areas vulnerable to climate change and sea level rise. The work of the Task Team should ultimately assist the Governments concerned in mitigating the impacts of such changes.

    2013-10-01

    Olympic shooters discharge, annually, thousands of tons of lead shot which pose toxic risks to animals and may pollute both surface and ground waters. Non-toxic steel shot is an acceptable and effective substitute, but International Shooting Sports Federation (ISSF) rules prevent its adoption. The present policy and rules of the ISSF on lead shot use contravene the International Olympic Committee (IOC) Charter position on environmental protection. The United Nations Environment Programme (UNEP), a formal Olympic partner on environmental protection, has no stated policy on contamination from lead ammunition, despite having declared lead a Priority Area for remedial action, and is pressing to remove lead from the global human environment. The IOC Sport and Environment Commission and UNEP could examine the continued use of lead shot ammunition and advise the IOC Executive Board on appropriate changes in policy and rules that could halt the massive lead shot contamination of shooting range environments world-wide.

  12. The emissions gap report 2012. A UNEP synthesis report

    2012-11-15

    One of the fundamental questions in the global climate negotiations is: what level of ''ambition'', in terms of collective emission reductions, is needed to protect global climate? To help answer this question UNEP and the scientific community have published a series of reports on the ''emissions gap1'' since 2010. Of particular interest to the ambition question is the gap in 2020 between emission levels consistent with the 2 deg. C climate target and emissions levels projected if country reduction pledges are fulfilled. If there is a gap, then there is doubt that the ambition of countries is great enough to meet the agreed-upon 2 deg. C climate target. In the 2010 Emissions Gap Report, scientists indicated that there would likely be a substantial emissions gap in 2020, although estimates of this gap ranged widely, depending on assumptions about how country pledges would be complied with. In the 2011 Bridging the Emissions Gap Report, scientists noted that enough technical potential existed to close the gap in 2020, but fast action by countries was needed. UNEP has now convened a group of 55 scientists and experts from 43 scientific groups across 22 countries to produce this third emissions gap report which covers the following: 1) An update of global greenhouse gas emission estimates, based on a number of different authoritative scientific sources; 2) An overview of national emission levels, both current (2010) and projected (2020) consistent with current pledges and other commitments; 3) An estimate of the level of global emissions consistent with the two degree target in 2020, 2030 and 2050; 4) An update of the assessment of the emissions gap for 2020; 5) A review of selected examples of the rapid progress being made in different parts of the world to implement policies already leading to substantial emission reductions. These policies could contribute significantly to narrowing the gap if they are scaled up and replicated in other countries. (Author)

    International Nuclear Information System (INIS)

    1981-05-01

    The water hyacinth project was initially proposed at the Regional Workshop on Rural Technology held at Dacca in January 1978. In November 1978, national coordinators met at New Delhi and outlined the project in detail as reported in CSC(79)RT-4. The meeting was attended by delegates from Bangladesh, Egypt, Guyana, India, Malaysia, Papua New Guinea, Sri Lanka, Commonwealth Science Council and the United Nations Environment Programme. Following this a proposal was submitted to UNEP seeking funding support to meet the external cost component of the project. This support was subsequently granted. The project aims to achieve an integrated approach towards managing water hyacinth. The underlying intention was that management would cover both eradication of the plant as well as making productive use of it when possible. Productive uses envisaged include biogas synthesis, production of papers and boards and as a source of proteins. Another interesting possibility is the use of the plant to control industrial as well as domestic water pollution . All these were detailed in a three and a half year time plan. The project had its first review meeting in June 1979 in Papua New Guinea. The major intention of this meeting was to examine status reports from each country in an attempt to quantify the problem caused by water hyacinth and assess the work plan in relation to this. The report of this meeting has been published as CSC(79)RT-5. At this meeting Papua New Guinea decided to withdraw from this project as water hyacinth was not regarded as a severe problem. The use of dugong as a control agent was not recommended by Papua New Guinea. In April 1980 an interim review meeting attended by the Regional Coordinator and representatives of UNEP and CSC was held in London where, based on the progress made in the participating countries, activities and time schedules were refined and sharpened (CSC (80)RT-16). It look some time to resolve the external funding question . It was

    Access to energy is one of the basic requirements for human development. To meet these growing energy needs without creating negative side effects is a challenge. The possibility of global climate change resulting from an increase in GHG concentrations in the atmosphere due to developmental activities is a major global concern. India is passing through the process of economic growth. Although India has not created the problem of climate change, India stands ready to be a part of the solution. The largest chunk of emissions was from electricity generation amounting to 65 percent of the total CO 2 equivalent emissions from the energy sector. Nuclear energy and renewables stand as sources for electricity with minimum GHG emission. Production of electricity from any form of primary energy has some environmental effect. A balanced assessment is needed. Nuclear power is of importance to India because it has potentially unlimited resource base, does not emit GHGs and, depending on location, has potentially favourable economics versus coal. In the long term, if we are to preserve the environment, it will be necessary to tap this source to the maximum extent feasible, In nuclear power stations, all its wastes are contained. India being home to nearly a third of the entire world's thorium, the strategies for large scale deployment of nuclear energy is focused towards utilization of thorium. The electricity potential of 3-stage programme is estimated to be about 2 lakh GWe-yr. Nuclear Power Corporation of India Limited is currently operating 20 reactors and has accumulated more than 337 reactor-years of experience in safe operation. A defence-in-depth approach is at the heart of safety philosophy, where there are several lines of defence, one backing another. Radiation is relevant for nuclear, coal, oil, gas and geothermal power plants. The essential task is to prevent excessive amounts now or in the future. One of the guiding principles adopted is to ensure that radiation

    The UNEP (United Nations Environment Programme) programme of Greenhouse Gas Abatement Costing Studies is intended to clarify the economic issues involved in assessing the costs of limiting emissions of greenhouse gases and to propose approaches to comparable costing studies. Phase 1 of the Zimbabwe country study describes the current energy situation in Zimbabwe related to the national economy, energy supply and demand and amounts of greenhouse gas emissions. Factors regarding the geography, (including a map illustrating the degree and character of land degradation by erosion) population, politics, international relations, land-use and management of the energy sector are dealt with in detail and the text is illustrated with data compiled from the study. It is estimated that Zimbabwe consumed 270.4 Tj of energy during 1988 and emitted 21.7 tonnes of carbon dioxide. An emission intensity of 80.2 tonnes/Tj for the whole economy and 63.6 tonnes/Tj for electric power generation alone was calculated. Forecasting for the year 2020 estimated carbon dioxide emission intensities of 73.5 tonnes/Tj for the whole economy and 43.7 tonnes for power generation. Net carbon dioxide emissions are predicted to be 30-42 tonnes during 2020. (AB).

    In spite of many years’ efforts, it is difficult to prove substantial improvements of the work environment and policymakers are continuously searching for new efficient strategies. This paper examines the concept of orchestration of work environment programs, based on an empirical analysis...... of recent Danish policy. Orchestration is a strategy where different stakeholders and activities are integrated into a unified program aimed at a specific target group. The analysis includes three policy cases, supplemented with two company case studies. The research shows a move toward a more governance...... type of regulation, which is not only emerging in network but also includes more explicitly orchestrated policy programs. The stakeholders participate in the network with different interests and the orchestration of work environment policies is therefore built on a platform of regulation...

    In December 1987, a WHO-UNEP meeting held at SCPRI (Service Central de protection canter Les Rayonnements Ionisantes - Le Vesinet, France) set up the basis of the international network GERMON (Global Environmental Radiation Monitoring Network) as an extension of existing network 'Global Environment Monitoring Systems' (GEMS). The accident from Chernobyl certainly was the important nuclear event influencing this decision. The aim of the GERMON network is to initiate programmes for the routine monitoring of the environmental radioactivity and to ensure a quick interchange of credible data in case of major accidental radioactive releases, as well as the development of intervention devices in the member states running such programmes. The responsibility of the Co-ordinating Collaborating Centre (CCC) has been given to the French Service Central de Protection Centre les Rayonnements Ionisants (SCPRI). In 1994, this Service became the Office de Protection Centre les Rayonnements Ionisants (OPRI). The Ministry of Health has a national network consisting of 23 radiation hygiene laboratories; 19 of these are included in the framework of county divisions of public health , and the other 4 are compartments of the regional institutes of public health. WHO designated the Institute of Public Health from Bucharest as National Contact Centre, in charge with communicating the results obtained by the national laboratories on the indicators of environmental radioactivity, according to the established methodologies. The main indicators considered are: ambient gamma dose, radioactivity of the air, of the precipitation, and of the milk. Following the measurement and transmission protocols of the CCC, the Radiation Hygiene Laboratory from the Institute of Public Health has established a methodology to be followed by the laboratories of the national network.

The GUI provides access to a Visual Programming Language (VPL) environment and a text editor. In executing a method, the VPL is opened, a task for the robot is built from the code library blocks, and data is assigned to input and output connections identifying input and output data for each block. A task sequence(s) is sent to the control module(s) over the NTL to command execution of the task.

  7. Indoor Environment Program - 1996 Annual Report

    Indoor Environment Program

    1996-11-01

    The forty-five chemists, physicists, biologists, architects, engineers, staff, and students of the Indoor Environment Program are all working to solve the problems of indoor air quality, health, comfort, and energy use associated with the indoor environment. A common thread throughout this work is the importance of ventilation--both for its role in supporting human health and comfort as well as for its liability in requiring large amounts of energy to heat and cool it. The importance of understanding these interactions can be illustrated by two examples: the health and productivity of workers (Fisk and Rosenfeld, 1996) and the performance of sensitive equipment in clean room environments (Faulkner, et d., 1996). During the past year, we estimated the magnitudes of health and productivity gains that may be obtained by providing better indoor environments. The ratio of the potential financial benefits of improving indoor environments to the costs of the improvements ranges between 20 and 50. A second example is from our Clean Room Energy Efficiency Study: Clean rooms utilize large amounts of electricity to operate fans that recirculate air at very high flow rates through particle filters. Usually, the fans operate continuously at full speed, even when the clean room is unused. To reduce the energy use in a research clean room, the rate of air recirculation was controlled in response to real-time measurements of particle concentration. With this new control system, fan energy use decreased by 65% to 85% while maintaining particle concentrations below the allowable limits except during occasional one-minute periods. The estimated payback period for this technology is one to four years.

    Buildings use approximately one-third of the energy consumed in the United States. The potential energy savings derived from reduced infiltration and ventilation in buildings are substantial, since energy use associated with conditioning and distributing ventilation air is about 5.5 EJ per year. However, since ventilation is the dominant mechanism for removing pollutants from indoor sources, reduction of ventilation can have adverse effects on indoor air quality, and on the health, comfort, and productivity of building occupants. The Indoor Environment Program in LBL`s Energy and Environment Division was established in 1977 to conduct integrated research on ventilation, indoor air quality, and energy use and efficiency in buildings for the purpose of reducing energy liabilities associated with airflows into, within, and out of buildings while maintaining or improving occupant health and comfort. The Program is part of LBL`s Center for Building Science. Research is conducted on building energy use and efficiency, ventilation and infiltration, and thermal distribution systems; on the nature, sources, transport, transformation, and deposition of indoor air pollutants; and on exposure and health risks associated with indoor air pollutants. Pollutants of particular interest include radon; volatile, semivolatile, and particulate organic compounds; and combustion emissions, including environmental tobacco smoke, CO, and NO{sub x}.

    Experience using the Argonne-developed PARMACs macro package to implement a portable parallel programming environment is described. Fortran programs with intrinsic parallelism of coarse and medium granularity are easily converted to parallel programs which are portable among a number of commercially available parallel processors in the class of shared-memory bus-based and local-memory network based MIMD processors. The parallelism is implemented using standard UNIX (tm) tools and a small number of easily understood synchronization concepts (monitors and message-passing techniques) to construct and coordinate multiple cooperating processes on one or many processors. Benchmark results are presented for parallel computers such as the Alliant FX/8, the Encore MultiMax, the Sequent Balance, the Intel iPSC/2 Hypercube and a network of Sun 3 workstations. These parallel machines are typical MIMD types with from 8 to 30 processors, each rated at from 1 to 10 MIPS processing power. The demonstration code used for this work is a Monte Carlo simulation of the response to photons of a ''nearly realistic'' lead, iron and plastic electromagnetic and hadronic calorimeter, using the EGS4 code system. 6 refs., 2 figs., 2 tabs

    This document provides a description of the Real Time Programming Environment (RTProE). RTProE tools allow a programmer to create soft real time projects under general, multi-purpose operating systems. The basic features necessary for real time applications are provided by RTProE, leaving the programmer free to concentrate efforts on his specific project. The current version supports Microsoft Windows{trademark} 95 and NT. The tasks of real time synchronization and communication with other programs are handled by RTProE. RTProE includes a generic method for connecting a graphical user interface (GUI) to allow real time control and interaction with the programmer`s product. Topics covered in this paper include real time performance issues, portability, details of shared memory management, code scheduling, application control, Operating System specific concerns and the use of Computer Aided Software Engineering (CASE) tools. The development of RTProE is an important step in the expansion of the real time programming community. The financial costs associated with using the system are minimal. All source code for RTProE has been made publicly available. Any person with access to a personal computer, Windows 95 or NT, and C or FORTRAN compilers can quickly enter the world of real time modeling and simulation.

    With this fourth assessment of the gap between ambitions and needs, the United Nations Environment Programme seeks to inform governments and the wider public on how far the response to climate change has progressed over the past year, and thus whether the world is on track to meet the 2 deg. C target. In addition to reviewing national pledges and actions, this year's assessment, for the first time, also reviews international cooperative initiatives which, while potentially overlapping, serve to complement national pledges and actions. From a technical standpoint, meeting the 2 deg. C target remains possible: it will take a combination of full implementation of current national pledges and actions, a scaling up of the most effective international cooperative initiatives, and additional mitigation efforts at the country level. All these efforts will require strengthened policies aimed at curbing greenhouse gas emissions. Crucially, they also require the promotion of development pathways that can concomitantly reduce emissions. As in the previous assessment, this year's report provides updated analyses of a number of tried and tested sector-specific policy options to achieve this goal. Specifically, we show that actions taken in the agricultural sector can lower emissions and boost the overall sustainability of food production. Replicating these successful policies, and scaling them up, would provide one option for countries to go beyond their current pledges and help close the 'emissions gap'. (LN)

    Techniques are disclosed for loading programs efficiently in a parallel computing system. In one embodiment, nodes of the parallel computing system receive a load description file which indicates, for each program of a multiple program multiple data (MPMD) job, nodes which are to load the program. The nodes determine, using collective operations, a total number of programs to load and a number of programs to load in parallel. The nodes further generate a class route for each program to be loaded in parallel, where the class route generated for a particular program includes only those nodes on which the program needs to be loaded. For each class route, a node is selected using a collective operation to be a load leader which accesses a file system to load the program associated with a class route and broadcasts the program via the class route to other nodes which require the program.

  5. Using Programming Environments in Teaching GIS Concepts

    Directory of Open Access Journals (Sweden)

    Imre Bornemisza

    2009-03-01

    Full Text Available When teaching Geographical Information Systems (GIS it is important to explain the theoretical elements, but it is also necessary to illustrate the basic functions with examples. To help students it is advisable to separate the teaching of fundamentals from the practical application of complex GIS software. A simple programming language like Logo creates opportunities for acquiring knowledge in an easy way. The development of a program makes it possible tounderstand the most important categories. If the program contains query functions as well, students can learn more about problem solution methods.This paper also demonstrates the power of the Logo family of languages which is delivered by different implementations. Elica Logo is used to build simple GIS tools that provide a very widerange of educational problems and lead to numerous ideas for further explorations. The nice intuitive 3D interface is an attractive approach to gain and retain student’s engagement in thelearning process.

  9. Factors Influencing Learning Environments in an Integrated Experiential Program

    Science.gov (United States)

    Koci, Peter

    The research conducted for this dissertation examined the learning environment of a specific high school program that delivered the explicit curriculum through an integrated experiential manner, which utilized field and outdoor experiences. The program ran over one semester (five months) and it integrated the grade 10 British Columbian curriculum in five subjects. A mixed methods approach was employed to identify the students' perceptions and provide richer descriptions of their experiences related to their unique learning environment. Quantitative instruments were used to assess changes in students' perspectives of their learning environment, as well as other supporting factors including students' mindfulness, and behaviours towards the environment. Qualitative data collection included observations, open-ended questions, and impromptu interviews with the teacher. The qualitative data describe the factors and processes that influenced the learning environment and give a richer, deeper interpretation which complements the quantitative findings. The research results showed positive scores on all the quantitative measures conducted, and the qualitative data provided further insight into descriptions of learning environment constructs that the students perceived as most important. A major finding was that the group cohesion measure was perceived by students as the most important attribute of their preferred learning environment. A flow chart was developed to help the researcher conceptualize how the learning environment, learning process, and outcomes relate to one another in the studied program. This research attempts to explain through the consideration of this case study: how learning environments can influence behavioural change and how an interconnectedness among several factors in the learning process is influenced by the type of learning environment facilitated. Considerably more research is needed in this area to understand fully the complexity learning

    The paper describes and illustrates an environment for interactive support of the detection and implementation of macro-level parallelism in Fortran programs. The approach couples algorithms for dependence analysis with both innovative techniques for complexity management and capabilities for the measurement and analysis of the parallel computation structures generated through use of the environment. The resulting environment is complementary to the more common approach of seeking local parallelism by loop unrolling, either by an automatic compiler or manually. (orig.)

    Liu, Allison S.; Schunn, Christian D.; Flot, Jesse; Shoop, Robin

    2013-12-01

    Computer science proficiency continues to grow in importance, while the number of students entering computer science-related fields declines. Many rich programming environments have been created to motivate student interest and expertise in computer science. In the current study, we investigated whether a recently created environment, Robot Virtual Worlds (RVWs), can be used to teach computer science principles within a robotics context by examining its use in high-school classrooms. We also investigated whether the lack of physicality in these environments impacts student learning by comparing classrooms that used either virtual or physical robots for the RVW curriculum. Results suggest that the RVW environment leads to significant gains in computer science knowledge, that virtual robots lead to faster learning, and that physical robots may have some influence on algorithmic thinking. We discuss the implications of physicality in these programming environments for learning computer science.

    Programming models and environments play the essential roles in high performance computing of enabling the conception, design, implementation and execution of science and engineering application codes. Programmer productivity is strongly influenced by the effectiveness of our programming models and environments, as is software sustainability since our codes have lifespans measured in decades, so the advent of new computing architectures, increased concurrency, concerns for resilience, and the increasing demands for high-fidelity, multi-physics, multi-scale and data-intensive computations mean that we have new challenges to address as part of our fundamental R&D requirements. Fortunately, we also have new tools and environments that make design, prototyping and delivery of new programming models easier than ever. The combination of new and challenging requirements and new, powerful toolsets enables significant synergies for the next generation of programming models and environments R&D. This report presents the topics discussed and results from the 2014 DOE Office of Science Advanced Scientific Computing Research (ASCR) Programming Models & Environments Summit, and subsequent discussions among the summit participants and contributors to topics in this report.

    To introduce a multiplatform, Python language-based, development environment called graphical programming interface for prototyping MRI techniques. The interface allows developers to interact with their scientific algorithm prototypes visually in an event-driven environment making tasks such as parameterization, algorithm testing, data manipulation, and visualization an integrated part of the work-flow. Algorithm developers extend the built-in functionality through simple code interfaces designed to facilitate rapid implementation. This article shows several examples of algorithms developed in graphical programming interface including the non-Cartesian MR reconstruction algorithms for PROPELLER and spiral as well as spin simulation and trajectory visualization of a FLORET example. The graphical programming interface framework is shown to be a versatile prototyping environment for developing numeric algorithms used in the latest MR techniques. © 2014 Wiley Periodicals, Inc.

    1992-01-01

    We report our experience in porting Linac application programs written for Camac controlled hardware consoles to an X-Windows/Motif based workstation environment. Application programs acquire their parameter values from a front end computer (FEC), controlling the acceleration process, via a local area network. The timing for data acquisition and control is determined by the particle source timing. Two server programs on the FEC for repetitive acquisition and command-response mode will be described. The application programs on the workstations access a common parameter access server who establishes the necessary connection to the parameters on the FEC. It displays the parameter's current values and allows control through Motif widgets. An interactive synoptics editor and its corresponding driver program allow easy generation of synoptics displays and interaction through command panels. (author)

    Walking is a preferred and recommended physical activity for middle-aged and older adults, but many barriers exist, including concerns about safety (ie, personal security), falling, and inclement weather. Mall walking programs may overcome these barriers. The purpose of this study was to summarize the evidence on the health-related value of mall walking and mall walking programs. We conducted a scoping review of the literature to determine the features, environments, and benefits of mall walking programs using the RE-AIM framework (reach, effectiveness, adoption, implementation, and maintenance). The inclusion criteria were articles that involved adults aged 45 years or older who walked in indoor or outdoor shopping malls. Exclusion criteria were articles that used malls as laboratory settings or focused on the mechanics of walking. We included published research studies, dissertations, theses, conference abstracts, syntheses, nonresearch articles, theoretical papers, editorials, reports, policy briefs, standards and guidelines, and nonresearch conference abstracts and proposals. Websites and articles written in a language other than English were excluded. We located 254 articles on mall walking; 32 articles met our inclusion criteria. We found that malls provided safe, accessible, and affordable exercise environments for middle-aged and older adults. Programmatic features such as program leaders, blood pressure checks, and warm-up exercises facilitated participation. Individual benefits of mall walking programs included improvements in physical, social, and emotional well-being. Limited transportation to the mall was a barrier to participation. We found the potential for mall walking programs to be implemented in various communities as a health promotion measure. However, the research on mall walking programs is limited and has weak study designs. More rigorous research is needed to define best practices for mall walking programs' reach, effectiveness, adoption

    2003-01-01

    In this paper we describe an Assertion Checking Environment (ACE) for compositional verification of programs, which are written in an industrially sponsored safe subset of C programming language called MISRA C [Guidelines for the Use of the C Language in Vehicle Based Software, 1998]. The theory is based on Hoare logic [Commun. ACM 12 (1969) 576] and the C programs are verified using static assertion checking technique. First the functional specifications of the program, captured in the form of pre- and post-conditions for each C function, are derived from the specifications. These pre- and post-conditions are then introduced as assertions (also called annotations or formal comments) in the program code. The assertions are then proved formally using ACE and theorem proving tool called Stanford Temporal Prover [The Stanford Temporal Prover User's Manual, 1998]. ACE has been developed by us and consists mainly of a translator c2spl, a GUI and some utility programs. The technique and tools developed are targeted towards verification of real-time embedded software

    Member State Support Program (MSSP) is comprised of various programs such as development of safeguards approach, training, information analysis and so on. Each support programs would be evaluated biennially through coordinators' meeting. IAEA publish 'Development and Implementation Support Programme for Nuclear Verification' so that the member state can review it. In the program, IAEA specify the need to develop the virtual reality based training tools. The objective of this project is to develop comprehensive training software dedicated to verification activities in the field based on the virtual environment. The training for the IAEA inspector is indispensable to maintain or improve their verification capability and to be prepared for the inspection of the complicated facilities. However, the grabbing of the available facility is not easy due to following limitations such as security, confidentiality, interference of the commercial operation and so on. Therefore, the virtual environment, which can replace a real facility, is required for the IAEA training. The objective of this software is to support the IAEA's verification capability. It is useful for the trainer and trainee to better understand how nuclear materials are processed in the fuel fabrication facility and what kind safeguards approaches are needed at each process before inspections. The final product will be integrated in the IAEA safeguards training courses to improve the efficiency of the safeguards training. Also we are going to make a decision if additional projects such as CANDU fuel parts or other facilities depending on evaluation results at the IAEA training course will be held on Korea in this year

    1999-01-01

    Full Text Available Recent developments in processor capabilities, software tools, programming languages and programming paradigms have brought about new approaches to high performance computing. A steadfast component of this dynamic evolution has been the scientific community’s reliance on established scientific packages. As a consequence, programmers of high‐performance applications are reluctant to embrace evolving languages such as Java. This paper describes the Java‐to‐C Interface (JCI tool which provides application programmers wishing to use Java with immediate accessibility to existing scientific packages. The JCI tool also facilitates rapid development and reuse of existing code. These benefits are provided at minimal cost to the programmer. While beneficial to the programmer, the additional advantages of mixed‐language programming in terms of application performance and portability are addressed in detail within the context of this paper. In addition, we discuss how the JCI tool is complementing other ongoing projects such as IBM’s High‐Performance Compiler for Java (HPCJ and IceT’s metacomputing environment.

    Exascale systems, with a thousand times the compute capacity of today’s leading edge petascale computers, are expected to emerge during the next decade. Their software systems will need to facilitate the exploitation of exceptional amounts of concurrency in applications, and ensure that jobs continue to run despite the occurrence of system failures and other kinds of hard and soft errors. Adapting computations at runtime to cope with changes in the execution environment, as well as to improve power and performance characteristics, is likely to become the norm. As a result, considerable innovation is required to develop system support to meet the needs of future computing platforms. The XPRESS project aims to develop and prototype a revolutionary software system for extreme-­scale computing for both exascale and strong­scaled problems. The XPRESS collaborative research project will advance the state-­of-­the-­art in high performance computing and enable exascale computing for current and future DOE mission-­critical applications and supporting systems. The goals of the XPRESS research project are to: A. enable exascale performance capability for DOE applications, both current and future, B. develop and deliver a practical computing system software X-­stack, OpenX, for future practical DOE exascale computing systems, and C. provide programming methods and environments for effective means of expressing application and system software for portable exascale system execution.

    1993-01-01

    Rhone-Poulenc (RP; Paris) made further progress last year in its pollution-reducing efforts, under the group's worldwide three-year Environment Plan (1992--1994). The company's water index improved by 15% from 1991 and by 22% from 1990 -- slightly ahead of target. The air index improved 9% from 1991 and 15% from 1990. open-quotes Progress regarding atmospheric emissions is significant, but we wish to go further in order to reach our medium-term objectives,close quotes says RP vice-chairman Jean-Marc Bruel. About 47% of the company's capital spending in 1992 was devoted to these emissions. The solid waste index remained static, with an improvement of 1% compared with an 18% advance in 1991. The startup of incineration units in 1993 will help correct this situation. Bruel reiterates the group's established goal of a 50% reduction in all effluent and solid waste by 1995, and 65% by 2000, using 1990 as the base year for its environment index. He says the indices have been adopted by the French chemical industry association -- Union des Industries Chimiques -- and the U.K.'s Chemical Industries Association. RP's environment-related expenditures in 1992 amounted to F1.8 billion ($330 million), of which F1.2 billion was for operating expenses and the remainder for new investments. Expenditures in France were F594 million and F479 million, respectively; the US, F381 million and F122 million; and Brazil F64 million and F14 million. Spending is forecast to be at a similar level in 1993. Environmental research, with spending of F5.8 billion in 1992, is integrated into all the group's research programs

    2013-10-12

    Simulation studies allow researchers to answer specific questions about data analysis, statistical power, and best-practices for obtaining accurate results in empirical research. Despite the benefits that simulation research can provide, many researchers are unfamiliar with available tools for conducting their own simulation studies. The use of simulation studies need not be restricted to researchers with advanced skills in statistics and computer programming, and such methods can be implemented by researchers with a variety of abilities and interests. The present paper provides an introduction to methods used for running simulation studies using the R statistical programming environment and is written for individuals with minimal experience running simulation studies or using R. The paper describes the rationale and benefits of using simulations and introduces R functions relevant for many simulation studies. Three examples illustrate different applications for simulation studies, including (a) the use of simulations to answer a novel question about statistical analysis, (b) the use of simulations to estimate statistical power, and (c) the use of simulations to obtain confidence intervals of parameter estimates through bootstrapping. Results and fully annotated syntax from these examples are provided.

    Full Text Available Simulation studies allow researchers to answer specific questions about data analysis, statistical power, and best-practices for obtainingaccurate results in empirical research. Despite the benefits that simulation research can provide, many researchers are unfamiliar with available tools for conducting their own simulation studies. The use of simulation studies need not be restricted toresearchers with advanced skills in statistics and computer programming, and such methods can be implemented by researchers with a variety of abilities and interests. The present paper provides an introduction to methods used for running simulationstudies using the R statistical programming environment and is written for individuals with minimal experience running simulation studies or using R. The paper describes the rationale and benefits of using simulations and introduces R functions relevant for many simulation studies. Three examples illustrate different applications for simulation studies, including (a the use of simulations to answer a novel question about statistical analysis, (b the use of simulations to estimate statistical power, and (c the use of simulations to obtain confidence intervals of parameter estimates throughbootstrapping. Results and fully annotated syntax from these examples are provided.

    Since the Clean Development Mechanism (CDM) was defined at Conference of the Parties 3 in Kyoto 1997, it took the international community another 4 years to reach the Marrakesh Accords in which the modalities and procedures to implement the CDM was elaborated. Even if more detailed rules, procedures and modalities have to be further developed a general framework to implement the CDM and other Kyoto mechanisms are now in place. This guidebook is produced to support the UNEP project 'Capacity Development for the Clean Development Mechanism'. Focus is on the CDM project cycle, the Project Design Document (PDD), and related issues such as sustainable development goals, financing and market intelligence. The appendices present frequently asked questions and answers, a short overview of existing guidelines and a possible future list of eligible CDM projects categories. (BA)

  19. State of the environment: selected topics, 1979. [Annual report of Executive Director, UN Environment Program

    Energy Technology Data Exchange (ETDEWEB)

    1979-01-01

    This annual report of the Executive Director, UN Environment Program, to the Governing Council of the United Nations focuses on four topics of global significance: schistosomiasis, pesticide resistance, noise pollution, and tourism. The four topics, while not the only urgent ones, are important contemporary problems associated with the impacts of development and environmental management. The pressures of man's efforts to increase the agricultural base through irrigation and chemical pesticides have resulted in an unprecedented spread of infectious schistosomiasis and pesticide pollution. Industrialization and urbanization have raised noise levels until they represent serious health hazards. International tourism has grown to such proportions that hundreds of millions of individual trips are taken by the average public each year. The positive and negative aspects of these developments are examined in hopes of stimulating discussions that will lead to more desirable planning and management. 81 references. (DCK)

    functional programming (services). Then, the aspect of permanence or temporality will be addressed to determine the choice of appropriate technologies used in order to convey programmatic assertions into physical solutions. The nodes are meant to be as lightweight installments in the area as possible, but at the same time as durable and of good quality as to support positive social effects and reinforce building social capital in the area. The author believe that this emergency-based AT node scenario can be extrapolated to unbalanced housing areas being the result of urban sprawl, after being only slightly adjusted to local standards. But the main goal is to allow for efficient interventions in areas in dire needs and poor environments with limited resources or limited funds.

    Research in the Division's environmental science program includes air pollution, water pollution, and the effects of pollutants on man and natural ecosystems. Work has focused on the chemistry and physics of particle surfaces. Using the technique of electron spectroscopy for chemical analysis (ESCA), surface reactions of sulfur and nitrogen compounds have been studied, and results include the identification of new chemical forms of nitrogen on particle surfaces and evidence for the importance of particle surfaces in the catalysis of sulfur dioxide to sulfuric acid. The Division's work in water pollution has been devoted to the study of trace metals in the estuarine environment, especially in San Francisco Bay. Studies on the effect of dredging operations on trace metals in the Mare Island ship channel and on the distribution of cadmium in Bay sediments have been performed. Research has also been conducted on the distribution of trace elements between bound states on suspended particles and in solution in Bay waters. Research is being conducted on a variety of problems relating to effects of pollutants. Biological studies seeking to discover effects of specific environmental insults such as oxidants at the cellular level have been done, and epidemiological studies have been initiated on the impacts of trace metals on human health. Theoretical studies in an attempt to develop a basis for assessing the stability of ecological systems are also being undertaken.

    Our goals were toexamine the educational approachesused at radiation oncology residency programs nationwide andto evaluate program director(PD) and chief resident (CR) perceptions of their educational environment. We distributed a survey regarding curricular structure via email toall identified US radiation oncology residency PDs and CRs. Pearson χ 2 test was used toevaluate whether differences existed between answers provided by the 2 study populations. The survey was disseminated to 200 individuals in 85 US residency programs: 49/85PDs(58%)and 74/115 (64%)CRs responded. More than one-half of PDs and CRs report that attending physicians discussed management, reviewed contours, and conducted mock oral board examinations with the residents. At nearly 50% of programs, the majority of teaching conferences use a lecture-based approach, whereas only 20% reported predominant utilization of the Socratic method. However, both PDs (63%) and CRs (49%) reported that Socratic teaching is more effective than didactic lectures (16% and 20%, respectively), with the remainder responding that they are equally effective. Teaching sessions were reported to be resident-led ≥75% of the time by 50% of CRs versus 18% of PDs (P = .002). Significantly more CRs than PDs felt that faculty-led teaching conferences were more effective than resident-led conferences (62% vs 26%, respectively; P Socratic-based teaching conferences. Increased communication between PDs and CRs can better align perceptions with educational goals. Copyright © 2016 American Society for Radiation Oncology. Published by Elsevier Inc.

    1991-01-01

    The IOC-UNEP Review Meeting on Oceanographic Processes of Transfer and Distribution of Pollutants in the Sea was opened at the Ruder Boskovic Institute, Zagreb, Yugoslavia on Monday, 15 May 1989. Papers presented at the meeting dealt with physical and geochemical processes in sea-water and sediment in transport mixing and dispersal of pollutants. The importance of mesoscale eddies and gyres in the open sea, wind-driven currents and upwelling events in the coastal zone, and thermohaline processes in semi-enclosed bays and estuaries was recognized. There is strong evidence that non-local forcing can drive circulation in the coastal area. Concentrations, horizontal and vertical distributions and transport of pollutants were investigated and presented for a number of coastal areas. Riverine and atmospheric inputs of different pollutants to the western Mediterranean were discussed. Reports on two on-going nationally/internationally co-ordinated projects (MEDMODEL, EROS 2000) were presented. Discussions during the meeting enabled an exchange of ideas between specialists in different disciplines to be made. It is expected that this will promote the future interdisciplinary approach in this field. The meeting recognized the importance of physical oceanographic studies in investigating the transfer and distribution of pollutants in the sea and in view of the importance of the interdisciplinary approach and bilateral and/or multilateral co-operation a number of recommendations were adopted

    Recent trend in programming is changing from text based programming to visual programming. In the text-based environment, major amount of time is spent on program development and debugging. Visual programming environment makes the process of modeling and simulation more intuitive and creative. In this case the user spends more time on actual model building and later on the analysis phase of the design. The aim of this project is to design and develop a visual programming environment for the solution of the elliptical partial differential equations. The main core of this software package is based on advanced data structures including graph theory representations and generic trees for fast data linking and processing.

    2004-07-01

    The Clean Development Mechanism (CDM), an innovative cooperative mechanism under the Kyoto Protocol, is designed with the dual aim of assisting developing countries in achieving sustainable development (SD) and of assisting industrialised countries in achieving compliance with their greenhouse gas (GHG) emission reduction commitments. The SD dimension is not merely a requirement of the CDM; it should be seen as a main driver for developing country interest in participating in CDM projects. This is so, since apart from GHG emission reductions CDM projects will have a number of impacts in the host countries, including impacts on economic and social development and on the local environment. Furthermore, the selecting of the SD criteria and the assessment of the SD impacts are sovereign matters of the host countries in the current operationalisation of the Kyoto Protocol. National authorities can thus use the SD dimension to evaluate key linkages between national development goals and CDM projects, with the aim of selecting and designing CDM projects so that they create and maximise synergies with local development goals.

    When dealing with neutron radiation one of the keys to reducing worker exposure is to have as much distance and shielding between the radiation and the radiation worker as possible. Using a PC to control a process from a remote location allows the distance between the radiation worker and the radiation source to be increase. Increasing the distance at which radiation worker can control a process allows more shielding to be placed around the glovebox. There are many commercial packages that allow controlling remote processes with a PC. This paper shows how flexible the LabVIEW Graphical Programming Language can be in implementing the remote control of glovebox process

    EnCana in Ecuador is deeply committed through the sustainable development by minimizing and controlling hazards, while contributing to the well being of the people and protecting the environment of the communities where we operate, the health and safety of our employees, as well as preventing any loss and ensuring business continuity. To ensure a safe work environment for all our employees and Contractors, the Company has conducted a complete Risk Evaluation, considering: physical, biological, chemical, ergonomics and psychosocial factors. Based on this Map of Risks, the exposure level and the age of the employee, the Medical Department established four different routines of medical exams (pre-occupational and occupational), which are conducted on a regular two years basis, or even in a shorter period of time, if required. Additionally, medical exams are conducted when an employee is transferred to a different position. All employees have their own records, which document their medical shape when enrolled, at any time while working, and when the person leaves the Company. This allows diagramming the history of employees, the following information: X Axis (horizontal) Age of the employee when enrolled, years (chronological) and position when the exams are conducted. Y Axis (vertical) Capability in terms of percentage, of different organs and physiology (audiometric, ears, lungs, etc.). All this information is processed by the EHS Department, which in conjunction with other departments, plan improvement Safety measures to avoid the exposure of the employees to those factors above mentioned, minimizing potential losses and reducing dramatically costs of accidents and absenteeism. Exactly the same concept is being implemented with Contractors, which must also comply with these requirements. Follow-up of all recommendations is conducted on a regular basis by the Employees, Contractors and Management (Executive) EHS Committees. (author)

The United States Coast Guard (USCG) has been charged with implementing the provisions of the Oil Pollution Act of 1990 (OPA-90), as it pertains to marine transportation vessels and facilities. Among the provisions are requirements for vessel and facility owners and operators to develop comprehensive response plans that specifically match response resources to spill removal requirements. Meeting the response plan provisions of OPA-90 requires common standards for testing, selecting and assigning resources to anticipated response needs and objectively evaluating response plans for adequacy. In August of 1991, the USCG OPA-90 office approached ASTM to determine the feasibility of developing standards through that organizations procedures. Meetings were then held between the OPA-90 staff and members of the ASTM Committee F-20 on Hazardous Substances and Oil Spill Response. An agreement was reached to commence standards development in the areas of: Barriers, Skimmers, Treating Agents, Pumps, Beach Clean-up, Sorbents, Bioremediation, In-situ Burning, Temporary Storage Devices, Communications, Remote Sensing. It was recognized that ASTM and other organizational standards existed in several of these areas, but there were those where none were known to exist. Standards development was, therefore, expected to be a complicated and time-consuming process. Both the USCG OPA-90 and EC/EED offices required standards to be developed quickly, without subverting the ASTM process. Mechanical containment and recovery was considered to be the primary area of concern for both groups

  20. An overview of environment Canada's National Incinerator Testing and Evaluation Program (NITEP)

    1991-01-01

    In response to the many concerns associated with incineration, Environment Canada established the National Incineration Testing and evaluation Program (NITEP) in 1984. It's mission was to assess the incineration process as a means for disposal of MSW in Canada. The program primarily focused on the environment and health impacts of MSW incinerators by determining how design and operating conditions can be modified to reduce emissions of concern. In addition to developing better measuring and monitoring methods, supporting ash residue management research programs, NITEP established four major field projects to develop the data base necessary for national guidelines. This paper presents a brief overview of the most significant field program findings over the past six years and the rationale for the Canadian Council of Ministers of the Environment (CCME) Operating and Emissions Guidelines for MSW Incinerators published in June of 1989. In addition an overview of the ash work completed to date, and work still underway, will be presented

  1. Improving delivery of a health-promoting-environments program: experiences from Queensland Health.

    Science.gov (United States)

    Dwyer, S

    1997-01-01

    The purpose of this paper is to outline the key components of a statewide multisite health-promoting-environments program. Contemporary health-promotion programs in settings such as schools, workplaces and hospitals use organisational development theory to address the health issues of the setting, including the physical environment, the organisational environment, and the specific health needs of the employees and consumers of the service. Program principles include management of each project by the participant organisation or site (for example, a school or workplace), using resources available within the organisation and the local community, voluntary participation, social justice and participant-based priority setting, and evaluation and monitoring. Adoption of these principles implies a shift in the role of the health worker from implementer to facilitator. Based on the experience of Queensland Health, it is proposed that the essential building blocks of the health-promoting-environments program are an intersectoral policy base, a model for action, training and resources, local facilitators, support from local organisations, a supportive network of sites, marketing of the program, and a state-based evaluation and monitoring system. The program in Queensland was able to develop a significant number of these components over the 1990-1996 period. In regard to evaluation, process measures can be built around the program components; however, further research is required for development of impact indicators and benchmarks on quality.

  2. Environment of symbolic and graphic programming for the SYMPATI-2 line processor

    Fernandez, Pascal

    1991-01-01

    This research thesis reports the development of a programming environment which can be easily used at all levels of development of an application in the field of image processing. The author first presents different programming environments by distinguishing, on the one hand, languages or environments which are not specific to a machine, and, on the other hand, languages or environments which are dedicated to a specialised parallel architecture. Then, after a recall of the structure of the line processor from an operational point of view, the author proposes a detailed presentation of the 4LP language, i.e. the layer 0 of the environment. The three other layers are then presented. They respectively comprise a high level symbolic language, a user-friendly and interactive graphic tool, and an interactive graphic tool for the development of applications from programme icons

    2016-04-01

    Full Text Available This paper deals with fuzzy goal programming approach to solve fuzzy linear bilevel integer programming problems with fuzzy probabilistic constraints following Pareto distribution and Frechet distribution. In the proposed approach a new chance constrained programming methodology is developed from the view point of managing those probabilistic constraints in a hybrid fuzzy environment. A method of defuzzification of fuzzy numbers using ?-cut has been adopted to reduce the problem into a linear bilevel integer programming problem. The individual optimal value of the objective of each DM is found in isolation to construct the fuzzy membership goals. Finally, fuzzy goal programming approach is used to achieve maximum degree of each of the membership goals by minimizing under deviational variables in the decision making environment. To demonstrate the efficiency of the proposed approach, a numerical example is provided.

    1994-01-01

    Following the Chernobyl accident in 1986, a group of experts from the World Health Organization (WHO) and the United Nations Environment Program (UNEP) met in France to discuss and develop the basic principles of a global environmental radiation monitoring network (GERMON). The basic functions of this network were to provide regular reports on environmental radiation levels and to be in a position to provide reliable and accurate radiation measurements on a quick and accurate radiation measurements on a quick turnaround basis in the event of a major radiation release. By 1992, although 58 countries had indicated an interest in becoming a part of the GERMON system, only 16 were providing data on a regular basis. This paper traces the history of GERMON from its inception in 1987 through its activities during 1993-4. It details the objectives of the network, describes functions, lists its participants, and presents obstacles in the current network. The paper examines the data requirements for radiological emergency preparedness and offers suggestions for the current system. The paper also describes the growing need for such a network. To add a domestic perspective, the authors present a summary of the environmental monitoring information system that was used by the NRC in 1986 in its analyses of the Chernobyl incident. Then we will use this 1986 experience to propose a method for the use of GERMON should a similar occasion arise in the future

    Targeting occupational health and safety interventions to different groups of employees and sectors is important. The aim of this study was to explore the environment-intervention fit of a Danish psychosocial work environment intervention program for the residential and home care sector. Focus group interviews with employees and interviews with mangers were conducted at 12 selected workplaces and a questionnaire survey was conducted with managers at all 115 workplaces. The interventions enhanced the probability of employees experiencing more “good” work days, where they could make a difference to the lives of clients. The interventions may therefore be characterized as culturally compelling and having a good fit with the immediate work environment of employees. The interventions furthermore seemed to fit well with the wider organizational environment and with recent changes in the societal and economic context of workplaces. However, some workplaces had difficulties with involving all employees and adapting the interventions to the organization of work. The findings suggest that flexibility and a variety of strategies to involve all employees are important aspects, if interventions are to fit well with the care sector. The focus on employees' conceptualization of a “good” work day may be useful for intervention research in other sectors. PMID:26380356

    1995-02-01

    As the LDEF program draws to a close, it leaves in place the fundamental building blocks for a Space Environment and Effects (SEE) program. Results from LDEF data analyses and investigations now form a substantial core of knowledge on the long term effects of the space environment on materials, system and structures. In addition, these investigations form the basic structure of a critically-needed SEE archive and database system. An agency-wide effort is required to capture all elements of a SEE program to provide a more comprehensive and focused approach to understanding the space environment, determining the best techniques for both flight and ground-based experimentation, updating the models which predict both the environments and those effects on subsystems and spacecraft, and, finally, ensuring that this multitudinous information is properly maintained, and inserted into spacecraft design programs. Many parts and pieces of a SEE program already exist at various locations to fulfill specific needs. The primary purpose of this program, under the direction of the Office of Advanced Concepts and Technology (OACT) in NASA Headquarters, is to take advantage of these parts; apply synergisms where possible; identify and when possible fill-in gaps; coordinate and advocate a comprehensive SEE program. The SEE program must coordinate and support the efforts of well-established technical communities wherein the bulk of the work will continue to be done. The SEE program will consist of a NASA-led SEE Steering Committee, consisting of government and industry users, with the responsibility for coordination between technology developers and NASA customers; and Technical Working Groups with primary responsibility for program technical content in response to user needs. The Technical Working Groups are as follows: Materials and Processes; Plasma and Fields; Ionizing Radiation; Meteoroids and Orbital Debris; Neutral External Contamination; Thermosphere, Thermal, and Solar

    The major effort that NASA, initially with the help of the United States Air Force (USAF), carried out for 27 years to synthesize the experimental and theoretical results of space research related to energetic charged particles into a quantitative description of the terrestrial trapped radiation environment in the form of model environments is detailed. The effort is called the Trapped Radiation Environment Modeling Program (TREMP). In chapter 2 the historical background leading to the establishment of this program is given. Also, the purpose of this modeling program as established by the founders of the program is discussed. This is followed in chapter 3 by the philosophy and approach that was applied in this program throughout its lifetime. As will be seen, this philosophy led to the continuation of the program long after it would have expired. The highlights of the accomplishments are presented in chapter 4. A view to future possible efforts in this arena is given in chapter 5, mainly to pass on to future workers the differences that are perceived from these many years of experience. Chapter 6 is an appendix that details the chronology of the development of TREMP. Finally, the references, which document the work accomplished over these years, are presented in chapter 7

  4. Run-Time and Compiler Support for Programming in Adaptive Parallel Environments

    Directory of Open Access Journals (Sweden)

    Guy Edjlali

    1997-01-01

    Full Text Available For better utilization of computing resources, it is important to consider parallel programming environments in which the number of available processors varies at run-time. In this article, we discuss run-time support for data-parallel programming in such an adaptive environment. Executing programs in an adaptive environment requires redistributing data when the number of processors changes, and also requires determining new loop bounds and communication patterns for the new set of processors. We have developed a run-time library to provide this support. We discuss how the run-time library can be used by compilers of high-performance Fortran (HPF-like languages to generate code for an adaptive environment. We present performance results for a Navier-Stokes solver and a multigrid template run on a network of workstations and an IBM SP-2. Our experiments show that if the number of processors is not varied frequently, the cost of data redistribution is not significant compared to the time required for the actual computation. Overall, our work establishes the feasibility of compiling HPF for a network of nondedicated workstations, which are likely to be an important resource for parallel programming in the future.

    Johnson, Donna B; Smith, Lynne T; Bruemmer, Barbara

    2007-02-01

    Providing small grants to community organizations can be an effective way to encourage changes in the environment that support better nutrition. This is effective because these organizations can provide insights into their communities, ready-made relationships with community members, and the trust of the community. Small-grants programs are more likely to be successful when they are tailored to the needs of individual communities, led by organizations that have established reputations with the community, fully supported by the lead community organization, and engage local partners that complement the skills and resources of the lead organization. An evaluation of a small-grants program, Grants for Healthy Youth, found that grantees developed unique approaches to improving their community nutrition environments, gained experience and skills in program development, built partnerships, and received recognition for their project work. Grantees faced some common barriers, especially with program evaluation. Small-grants programs can be an effective way to improve community nutrition environments, but granting agencies need to provide effective technical assistance to communities throughout the process.

  14. Enhancement of the Work in Scia Engineer's Environment by Employment of XML Programming Language

    Directory of Open Access Journals (Sweden)

    Kortiš Ján

    2015-12-01

    Full Text Available The productivity of the work of engineers in the design of building structures by applying the rules of technical standards [1] has been increasing by using different software products for recent years. The software products offer engineers new possibilities to design different structures. However, there are problems especially for design of structures with similar static schemes as it is needed to follow the same work-steps. This can be more effective if the steps are done automatically by using a programming language for leading the processes that are done by software. The design process of timber structure which is done in the environment of Scia Engineer software is presented in the article.

    One of the main targets of the UNEP Greenhouse Gas Abatement Costing Study is combining the techno-economic and purely economic modelling approaches into one overall modelling methodology for greenhouse gas abatement costing studies. This type of models can be categorized as bottom-up models, since technology data on a very detailed level result in costs and emissions on a national level. In contrast with, but not necessarily in conflict with these models, macro-economists rely in general on macro-economic models which derive economic projections from aggregated national and sectorial economic data. These so called top-down models describe the complete national economy. Therefore the energy sector is modelled in a very aggregated way. Since the micro-economic and techno-economic approaches can be classified both as bottom-up approaches, it could be expected that mutual understanding exists. However, this is not true for all issues in this field. Techno-economical views and micro-economic views differ for instance on the implementation of options. This topic drew attention during the UNEP study, next to other items as techno-economic and macro-economic model assessments of the costs of CO 2 abatement. One of the most important implementation issues is the so-called negative cost (benefit) potential of energy saving options, which exists in the techno-economic view at this very moment, but which is not implemented yet. In the view of micro-economic analysis this potential does not exist, since options which are profitable would have been implemented according to presently adopted cost-benefit theory. Several aspects of this controversy have been discussed extensively elsewhere. In this paper the two visions are summarized and it is discussed whether it is fruitful to combine techno-economic and micro-economic approaches in an overall methodological framework. 1 tabs., 8 refs

    This paper presents the integration of a virtual environment (BlindAid) in an orientation and mobility rehabilitation program as a training aid for people who are blind. BlindAid allows the users to interact with different virtual structures and objects through auditory and haptic feedback. This research explores if and how use of the BlindAid in conjunction with a rehabilitation program can help people who are blind train themselves in familiar and unfamiliar spaces. The study, focused on nine participants who were congenitally, adventitiously, and newly blind, during their orientation and mobility rehabilitation program at the Carroll Center for the Blind (Newton, Massachusetts, USA). The research was implemented using virtual environment (VE) exploration tasks and orientation tasks in virtual environments and real spaces. The methodology encompassed both qualitative and quantitative methods, including interviews, a questionnaire, videotape recording, and user computer logs. The results demonstrated that the BlindAid training gave participants additional time to explore the virtual environment systematically. Secondly, it helped elucidate several issues concerning the potential strengths of the BlindAid system as a training aid for orientation and mobility for both adults and teenagers who are congenitally, adventitiously, and newly blind.

    This document describes in detail the ongoing and planned US Test program on the mechanical properties of sodium-exposed Type 316 austenitic stainless and Fe-2 1/4 Cr-1 Mo ferritic steels. The test program is based on the Development Requirement Specifications (DRS) established by the DOE/Clinch River Breeder Reactor Project (CRBRP) Program Office, the general need for the development of LMFBR structural-design criteria established by the Nuclear Systems Materials Handbook, and the need for a fundamental understanding of materials behavior in a sodium environment, which is generic to LMFBR systems. The planned test program is an extension of work based on current knowledge of sodium chemistry and the influence of sodium purity on the mechanical properties of structural materials

    International Nuclear Information System (INIS)

    2002-01-01

    This issue has come to the fore in recent years now that Norwegian military personnel have been sent to regions of the world where ammunition made of depleted uranium has been used. A number of surveys have been conducted in the Balkans, so far indicating no health hazards to people present in these areas. However, the latest international surveys show that contamination may be long-lasting. Tonje Sekse represented the Norwegian Radiation Protection Authority at the United Nations Environment Programme's (UNEP) inspection tour to Serbia and Montenegro in the autumn of 2001. The report, entitled ''Depleted uranium in Serbia and Montenegro - Post-Conflict Environmental Assessment in the Federal Republic of Yugoslavia'' was published by UNEP in March 2002.(author)

    It is becoming a popular practice for architects and HVAC engineers to simulate airflow in and around buildings by computational fluid dynamics (CFD) methods in order to predict indoor and outdoor environment. However, many CFD programs are crippled by a historically poor and inefficient user interface system, particularly for users with little training in numerical simulation. This investigation endeavors to create a simplified CFD interface (SCI) that allows architects and buildings engineers to use CFD without excessive training. The SCI can be easily integrated into new CFD programs. (author)

    It is exceedingly difficult to demonstrate definitive long-term changes in animal health as a result of acid-forming emissions from sour gas wells. A summary is presented of current research in Alberta, followed by the potential for research funding by the Alberta Government/Industry Acid Deposition Program (ADRP). The Alberta Environment research budget consists of four programs in addition to the ADRP: acid deposition effects research in the Athabasca oil sands; western and northern Canada long-range transport of air pollutants; departmental monitoring; and inhalation toxicology and animal health. Animal health research, although a component of the acid deposition issue, is beyond the mandate of Alberta Environment, and the ADRP members committee does not forsee becoming involved in the long-term and complex research required to address the effects of acid-forming emissions on livestock. Funds for additional animal health research must come from other government departments and agencies whose mandate covers this area

    The creation of psychophysical tasks for the behavioral neurosciences has generally relied upon low-level software running on a limited range of hardware. Despite the availability of software that allows the coding of behavioral tasks in high-level programming environments, many researchers are still reluctant to trust the temporal accuracy and resolution of programs running in such environments, especially when they run atop non-real-time operating systems. Thus, the creation of behavioral paradigms has been slowed by the intricacy of the coding required and their dissemination across labs has been hampered by the various types of hardware needed. However, we demonstrate here that, when proper measures are taken to handle the various sources of temporal error, accuracy can be achieved at the 1 ms time-scale that is relevant for the alignment of behavioral and neural events.

  6. A mixed-methods exploration of an environment for learning computer programming

    2015-08-01

    Full Text Available A mixed-methods approach is evaluated for exploring collaborative behaviour, acceptance and progress surrounding an interactive technology for learning computer programming. A review of literature reveals a compelling case for using mixed-methods approaches when evaluating technology-enhanced-learning environments. Here, ethnographic approaches used for the requirements engineering of computing systems are combined with questionnaire-based feedback and skill tests. These are applied to the ‘Ceebot’ animated 3D learning environment. Video analysis with workplace observation allowed detailed inspection of problem solving and tacit behaviours. Questionnaires and knowledge tests provided broad sample coverage with insights into subject understanding and overall response to the learning environment. Although relatively low scores in programming tests seemingly contradicted the perception that Ceebot had enhanced understanding of programming, this perception was nevertheless found to be correlated with greater test performance. Video analysis corroborated findings that the learning environment and Ceebot animations were engaging and encouraged constructive collaborative behaviours. Ethnographic observations clearly captured Ceebot's value in providing visual cues for problem-solving discussions and for progress through sharing discoveries. Notably, performance in tests was most highly correlated with greater programming practice (p≤0.01. It was apparent that although students had appropriated technology for collaborative working and benefitted from visual and tacit cues provided by Ceebot, they had not necessarily deeply learned the lessons intended. The key value of the ‘mixed-methods’ approach was that ethnographic observations captured the authenticity of learning behaviours, and thereby strengthened confidence in the interpretation of questionnaire and test findings.

    The Chemical, biological and radiological/nuclear Research and Technology Initiative (CRTI) is a program led by Canada's Department of National Defence in an effort to improve the capability of providing technical and analytical support in the event of a terrorist-related event. This paper summarized the findings from the CRTI Sample Triage Working Group and reviewed information on Environment Canada's triage program and its' mobile sample inspection facility that was designed to help examine samples of hazardous materials in a controlled environment to minimize the risk of exposure. A sample triage program is designed to deal with administrative, health and safety issues by facilitating the safe transfer of samples to an analytical laboratory. It refers to the collation of all results including field screening information, intelligence and observations for the purpose of prioritizing and directing the sample to the appropriate laboratory for analysis. A central component of Environment Canada's Emergency Response Program has been its capacity to respond on site during an oil or chemical spill. As such, the Emergencies Science and Technology Division has acquired a new mobile sample inspection facility in 2004. It is constructed to work with a custom designed decontamination unit and Ford F450 tow vehicle. The criteria and general design of the trailer facility was described. This paper also outlined the steps taken following a spill of hazardous materials into the environment so that potentially dangerous samples could be safety assessed. Several field trials will be carried out in order to develop standard operating procedures for the mobile sample inspection facility. 6 refs., 6 figs., 4 appendices.

  9. Structuring learning environments: Lessons from the organization of post-literacy programs

    Easton, Peter A.

    1989-12-01

    New conceptual and historical work on the nature of literacy and information on several bellwether post-literacy efforts in developing countries furnish a basis for diagnosing some of the deficiencies in current approaches to post-literacy programming. The key issue is the design of a `literate environment'. Heretofore attention has been concentrated too exclusively on the reading materials and continuing education side of the problem, and insufficient attention has been given to the more critical and difficult aspect: ensuring adequate opportunities for the application of new literate skills. The availability of these functional opportunities is closely related to the possibilities for accumulation and reinvestment of economic surplus in the environment, and to the way in which the related activities are organized. Literacy programs can unite skills relevant to management of local resources with strategies of cultural, political or religious revitalization that mobilize people to use their human resources. They therefore continue to offer an attractive means of initiating a reinvestment spiral from limited initial capital. To realize these potentials at the post-literacy stage, however, requires planning post-literacy before literacy, broadening programs to address primary school leavers as well, and paying greatly increased attention to the economic and social structure of the learning environment.

    2011-01-01

    The authors of the recently published Institute of Medicine on the Future of Nursing report emphasized the importance of preparing nurses to lead change to advance health care in the United States. Other scholars linked practice environments to safe quality care. In order for nurses to fully actualize this role in practice environments, they need to possess leadership skills sets that identify and respond to challenges faced. New nurses are no exception. This article presents a program with a 5-year track record that is designed to support transition and enhance the skill sets of leadership for new nurses in their first year of practice. Qualitative and quantitative evaluation measurements at baseline and postprogram provided data for evaluation of the first 4 cohorts in the program. Evaluative outcomes presented indicate that new nurses gained leadership and translational research skills that contributed to their ability to influence practice environments. Nonetheless, practice environments continue to need improvement and ongoing leadership from all levels of nursing must be upheld.

    Plutonium-fueled radioisotopic heat sources find application in a spectrum of space, terrestrial, and underseas applications to generate electrical power by thermoelectric or dynamic-cycle conversion. Such systems under postulated accident conditions could release radioactivity into the environment resulting in risks to the general population. The released radioactivity could be dispersed into various environmental media, such as air, soil, and water and interact with people through various exposure pathways leading to inhalation, ingestion, and external radiological doses and associated health effects. The authors developed short-term exposure (RISK II) and long-term exposure (RISK III) models for use in safety risk assessments of space missions utilizing plutonium-fueled electric power systems. To effectively use these models in risk assessments, representative input values must be selected for a spectrum of environmental transfer parameters that characterize the behavior of plutonium in the environment. The selection of appropriate transfer parameters to be used in a given analysis will depend on the accident scenarios to be modeled and the terrestrial and aquatic environments to be encountered. The authors reviewed the availability of plutonium environmental data for use in risk assessments and the status of research programs being conducted by various organizations related to the behavior of plutonium in the environment. This report summarizes the research programs presently being conducted at six Department of Energy Laboratories and makes recommendations on areas where further research is needed to fill gaps in the data necessary for risk assessments. 19 refs., 2 figs., 1 tab

    Several public health education programs and government agencies across the country have started offering virtual or online training programs in emergency preparedness for people who are likely to be involved in managing or responding to different types of emergency situations such as natural disasters, epidemics, bioterrorism, etc. While such online training programs are more convenient and cost-effective than traditional classroom-based programs, their success depends to a great extent on the underlying technological environment. Specifically, in an online technological environment, different types of user experiences come in to play-users' utilitarian or pragmatic experience, their fun or hedonic experience, their social experience, and most importantly, their usability experience-and these different user experiences critically shape the program outcomes, including course completion rates. This study adopts a multi-disciplinary approach and draws on theories in human computer interaction, distance learning theories, usability research, and online consumer behavior to evaluate users' experience with the technological environment of an online emergency preparedness training program and discusses its implications for the design of effective online training programs. . Data was collected using a questionnaire from 377 subjects who had registered for and participated in online public health preparedness training courses offered by a large public university in the Northeast. Analysis of the data indicates that as predicted, participants had higher levels of pragmatic and usability experiences compared to their hedonic and sociability experiences. Results also indicate that people who experienced higher levels of pragmatic, hedonic, sociability and usability experiences were more likely to complete the course(s) they registered for compared to those who reported lower levels. The study findings hold important implications for the design of effective online emergency

    The STA basic system has been enhanced to accelerate support for parallel programming on heterogeneous parallel computers, through a series of R and D on the technology of parallel processing. The enhancement has been made through extending the function of the PPDF, Parallel Program Development Environment in the STA basic system. The extended PPDE has the function to make: 1) the automatic creation of a 'makefile' and a shell script file for its execution, 2) the multi-tools execution which makes the tools on heterogeneous computers to execute with one operation a task on a computer, and 3) the mirror composition to reflect editing results of a file on a computer into all related files on other computers. These additional functions will enhance the work efficiency for program development on some computers. More functions have been added to the PPDE to provide help for parallel program development. New functions were also designed to complement a HPF translator and a parallelizing support tool when working together so that a sequential program is efficiently converted to a parallel program. This report describes the use of extended PPDE. (author)

    2016-06-01

    This study explored the intertwined effects between the policies and regulations of the companies and personal background on participation in the physical fitness programs and leisure-time activities in financial enterprises. A total of 823 employees were selected as the sample with the multilevel stratification random-sampling technique. The response rate was 52.0%. Data were analyzed with descriptive statistics and hierarchical linear logistic regression. Thirty-two percent and 39% of the employees participated in the physical fitness programs and leisure-time activities, respectively. The factors affecting participation were categorized into intrapersonal factors, interpersonal processes, and primary groups, as well as institutional factors. In the interpersonal processes and primary groups level, higher family social support, more equipment in health promotion was associated with more participation in the programs. With the influence from the institutional level, it was found that health promotion policy amplified the relationship between employees' age and participation, but attenuated the relationship between education level and participation. Health promotion equipment in the institutes attenuated the relationship between colleague social support, family social support, and education level with program participation. Physical activity equipment in the community attenuated the relationship between family social support and program participation. The influential factors of social support and worksite environment could predict the employees' participation in the physical fitness programs and leisure-time physical activities. Health promotion policy and equipment attenuated the negative effects of nonparticipation as well as amplified the positive effects of participation.

    2006-01-01

    This paper provides an overview of the eight components of a radiation safety program in a large health care facility spread out over several campuses in a large geographic area in Nova Scotia. The main focus is based on those areas that are regulated by the Canadian Nuclear Safety Commission and generally encompass nuclear medicine and radiation therapy operations. X-ray operations are regulated provincially, but the general operational principles of an effective radiation safety program can be applied in all these areas. The main components covered include the set up of an organizational structure that operates separately from individual departments, general items expected from reports to corporate management or regulators, and some examples of the front-line expectations for those in individual departments. The review is not all encompassing, but should give organizations some insight of the magnitude of a radiation safety program in a district style environment. (author)

    Lim, S. C.; Park, J. S.; Sohn, J. W.; Choi, S. B.

    This work presents a design and analysis program for vehicle devices utilizing an electrorheological (ER) fluid. The program is operated in graphic user interface (GUI) environment and the initial window is consisted of four subprogram modules which are related to ER shock absorber, ER seat damper, ER engine mount, and ER anti-lock brake system (ABS), respectively. In order to execute each module, both material properties and design parameters are to be chosen by the user. Then, the output display window shows the field-dependent performance characteristics to be considered as design criteria. In addition, control performances of the vehicle system equipped with ER devices are displayed in time and frequency domain. In order to demonstrate the effectiveness of the proposed program, ER shock absorber and ER ABS are designed and manufactured and their performance characteristics are evaluated.

    2007-08-01

    Full Text Available This paper relates the experience that students have while accessing Virtual Property Manager (VPM, a Web-based simulation learning tool designed to introduce students to a new discipline being offered at the university – Residential Property Management. The VPM simulation was designed in part to develop student interest in the new program. Results indicate that this simple simulation device did make a notable impact on student interest. Additionally, student acceptance and self-reported impact differed significantly based upon the delivery context. Adding a competitive reward element to the simulation experience improved student's evaluation of the software and self-reported interest in the field. Results indicate that educational simulation evaluation, acceptance, and performance may often be substantially influenced by the delivery context, rather than simply the program itself. Developers may do well to focus "outside the box" of program content to promote audience-specific delivery environments.

    2009-01-01

    Many studies need to determine a subject's threshold for a given task. This can be achieved efficiently using an adaptive staircase procedure. While the logic and algorithms for staircases have been well established, the few pre-programmed routines currently available to researchers require at least moderate programming experience to integrate into new paradigms and experimental settings. Here, we describe a freely distributed routine developed for the E-Prime programming environment that can be easily integrated into any experimental protocol with only a basic understanding of E-Prime. An example experiment (visual temporal-order-judgment task) where subjects report the order of occurrence of two circles illustrates the behavior and consistency of the routine.

    In this paper Amoco Norway Oil Company's environmental program is detailed, followed by example operational programs and achievements aimed to minimize environmental risks to the marine environment at Valhall platform. With a corporate goal to be a leader in protecting the environment, the appropriate strategies and policies that form the basis of the environmental management system are incorporated in the quality assurance programs. Also, included in the program are necessary organizational structures, responsibilities of environmental affairs and line organization personnel, compliance procedures and a waste task force obliged to implement operations improvements. An internal environmental audit system has been initiated, in addition to corporate level audits, which, when communicated to the line organization closes the environmental management loop through experience feed back. Environmental projects underway are significantly decreasing the extent and/or risk of pollution from offshore activities. The cradle to grave responsibility is assumed with waste separated offshore and onshore followed by disposal in audited sites. A $5 MM program is underway to control produced oily solids and reduce oil in produced water aiming to less than 20 ppm. When oil-based mud is used in deeper hole sections, drill solids disposed at sea average less than 60 g oil/kg dry cuttings using appropriate shaker screens, and a washing/centrifuge system to remove fines. Certain oily liquid wastes are being injected down hole whereas previously they were burned using a mud burner. Finally, a program is underway with a goal to eliminate sea discharge of oil on cuttings through injection disposal of oily wastes, drilling with alternative muds such as a cationic water base mud, and/or proper onshore disposal of oily wastes

    Brief summaries are presented of some 35 individual programs covering a wide range of activities in the atmospheric, oceanographic, and terrestrial ecology areas. In general, these programs are involved with the study of pollutants resulting from the production of energy and their effects or potential effects on the environment. Programs include meteorology and plume dispersion, with emphasis on tracing plumes from the tall stacks of fossil-fuel burning power plants, and implementation of MAP3S (the Multistate Atmospheric Power Production Pollution Study), including both field and modeling studies related to atmospheric pollutants in the Northeastern United States, the meteorology of the coastal land-sea interface, the development of long-distance tracer systems for following movements of air masses, the measurement of a series of pollutants at ambient levels in real time, and laboratory and field studies on the collection and behavior of aerosol particulates, including work on the speciation and quantification of sulfate particulates. The objective of programs in oceanographic sciences is to assess the potential impact of energy-related activities (reactor releases, oil spills, etc.) on the Northeast coastal zone and its biota. A capability for the study of environmental virology has been established. Another major program is the study of the effects of acid rain on forest ecosystems and on selected crops.

    1980-03-01

    A computer program, PABLM, was written to facilitate the calculation of internal radiation doses to man from radionuclides in food products and external radiation doses from radionuclides in the environment. This report contains details of mathematical models used and calculational procedures required to run the computer program. Radiation doses from radionuclides in the environment may be calculated from deposition on the soil or plants during an atmospheric or liquid release, or from exposure to residual radionuclides in the environment after the releases have ended. Radioactive decay is considered during the release of radionuclides, after they are deposited on the plants or ground, and during holdup of food after harvest. The radiation dose models consider several exposure pathways. Doses may be calculated for either a maximum-exposed individual or for a population group. The doses calculated are accumulated doses from continuous chronic exposure. A first-year committed dose is calculated as well as an integrated dose for a selected number of years. The equations for calculating internal radiation doses are derived from those given by the International Commission on Radiological Protection (ICRP) for body burdens and MPC's of each radionuclide. The radiation doses from external exposure to contaminated water and soil are calculated using the basic assumption that the contaminated medium is large enough to be considered an infinite volume or plane relative to the range of the emitted radiations. The equations for calculations of the radiation dose from external exposure to shoreline sediments include a correction for the finite width of the contaminated beach

    The Insight Segmentation and Registration Toolkit (ITK) is a long-established, software package used for image analysis, visualization, and image-guided surgery applications. This package is a collection of C++ libraries, that can pose usability problems for users without C++ programming experience. To bridge the gap between the programming complexities and the required learning curve of ITK, we present a higher-level visual programming environment that represents ITK methods and classes by wrapping them into "blocks" within MATLAB's visual programming environment, Simulink. These blocks can be connected to form workflows: visual schematics that closely represent the structure of a C++ program. Due to the heavily C++ templated nature of ITK, direct interaction between Simulink and ITK requires an intermediary to convert their respective datatypes and allow intercommunication. We have developed a "Virtual Block" that serves as an intermediate wrapper around the ITK class and is responsible for resolving the templated datatypes used by ITK to native types used by Simulink. Presently, the wrapping procedure for SimITK is semi-automatic in that it requires XML descriptions of the ITK classes as a starting point, as this data is used to create all other necessary integration files. The generation of all source code and object code from the XML is done automatically by a CMake build script that yields Simulink blocks as the final result. An example 3D segmentation workflow using cranial-CT data as well as a 3D MR-to-CT registration workflow are presented as a proof-of-concept.

    Plutonium-fueled radioisotopic heat sources find application in a spectrum of space, terrestrial, and underseas applications to generate electrical power by thermoelectric or dynamic-cycle conversion. Such systems under postulated accident conditions could release radioactivity into the environment resulting in risks to the general population. The released radioactivity could be dispersed into various environmental media, such as air, soil, and water and interact with people through various exposure pathways leading to inhalation, ingestion, and external radiological doses and associated health effects. The authors developed short-term exposure (RISK II) and long-term exposure (RISK III) models for use in safety risk assessments of space missions utilizing plutonium-fueled electric power systems. To effectively use these models in risk assessments, representative input values must be selected for a spectrum of environmental transfer parameters that characterize the behavior of plutonium in the environment. The selection of appropriate transfer parameters to be used in a given analysis will depend on the accident scenarios to be modeled and the terrestrial and aquatic environments to be encountered. The authors reviewed the availability of plutonium in the environment. This report summarizes the research programs presently being conducted at six Department of Energy Laboratories and makes recommendations on areas where further research is needed to fill gaps in the data necessary for risk assessments

    Nitric oxide is essential in the vascular adaptation to pregnancy, as knockout mice lacking nitric oxide synthase (NOS3) have abnormal utero-placental perfusion, hypertension and growth restriction. We previously showed with ex vivo studies on transgenic animals lacking NOS3 that adverse intrauterine environment alters fetal programming of vascular reactivity in adult offspring. The current research shows that altered vascular reactivity correlates with higher blood pressure in vivo. Our data suggest that higher blood pressure depends on both genetic background (NOS3 deficiency) and uterine environment, becomes more evident with age (> 7 postnatal weeks), activity and stress, is gender specific (preponderant among males), and can be affected by the sleep-awake cycle. In utero or early postnatal life (programming is associated with abnormal blood pressure (BP) profiles in vivo. Mice lacking a functional endothelial nitric oxide synthase (KO, NOS3 -/- ) and wild-type mice (WT, NOS3 +/+ ) were crossbred to generate homozygous NOS3 -/- (KO), maternally derived heterozygous NOS3 +/- (KOM: mother with adverse intrauterine environment from NOS3 deficiency), paternally derived heterozygous NOS3 +/- (KOP: mother with normal in utero milieu) and NOS3 +/+ (WT) litters. BP was measured in vivo at 7, 14 and 21 weeks of age. After univariate analysis, multivariate population-averaged linear regression models were used to identify factors affecting BP. When compared to WT offspring, systolic (SBP), diastolic (DBP) and mean (MAP) BP progressively increased from KOP, to KOM, and peaked among KO (P 7 postnatal weeks), higher locomotor activity, daytime recordings, and recent blood pressure transducer insertion (P < 0.001). Post hoc analysis showed that KOM had higher SBP than KOP (P < 0.05). Our study indicates that adverse intrauterine environment contributes, along with multiple other factors, to account for hypertension; moreover, in utero or early postnatal life may represent

    Due-date assignment plays an important role in scheduling systems and strongly influences the delivery performance of job shops. Because of the stochastic and dynamic nature of job shops, the development of general due-date assignment models (DDAMs) is complicated. In this study, two genetic programming (GP) methods are proposed to evolve DDAMs for job shop environments. The experimental results show that the evolved DDAMs can make more accurate estimates than other existing dynamic DDAMs with promising reusability. In addition, the evolved operation-based DDAMs show better performance than the evolved DDAMs employing aggregate information of jobs and machines.

    The complexity of Valve Program development, planning, execution and management in a refurbishment environment is an enormous undertaking requiring the proper coordination and integration of many moving parts. As such, lack of attention and understanding of this complexity has led to significant cost and schedule overruns in past refurbishment projects in the province. OPEX indicates the challenges in completing valve scope during refurbishments are related but not limited to; lack of detailed condition assessments, improper scope development, insignificant strategic approach to work task planning, scheduling and procurement, absence of contingency planning for common ‘as found’ conditions during execution, lack of proper training requirements, etc. In addition, past contracting strategies to employ numerous companies in collaboration to complete such a complex and specialized program, has resulted in further complications surrounding the management and integration of multiple quality programs and internal company processes. Finally, the aftermath of such fragmented projects results in an absolute closeout nightmare, often times taking years to locate, sift through and re-integrate pertinent information back into customer systems. Valve Program complexity cannot be understood by just anyone, only those that have lived through a refurbishment project and experienced the challenges mentioned above have the knowledge, skill, and ability to appreciate how to tactically apply past learning to realize future improvements. Furthermore, effective contractor-customer collaboration is crucial; true and in-depth knowledge and understanding of the customer quality programs, engineering and work management processes, configuration management requirements, and most importantly the imperative significance of nuclear safety, are all essential components to ensure overall alignment and program success.

    Taibah University offers regular nursing (RNP) and nursing bridging (NBP) bachelor programs. We evaluated student perception of the learning environment as one means of quality assurance. To assess nursing student perception of their educational environment, to compare the perceptions of regular and bridging students, and to compare the perceptions of students in the old and new curricula. Cross-sectional survey. College of Nursing at Taibah University, Madinah, Saudi Arabia. The Dundee Ready Educational Environment Measure (DREEM) instrument was distributed to over 714 nursing students to assess perception of the educational environment. Independent samples t test and Pearson's chi square were used to compare the programs and curricula. The DREEM inventory score. Of 714 students, 271 (38%) were RNP students and 443 (62%) were NBP students. The mean (standard deviation) DREEM score was 111 (25). No significant differences were observed between the programs except for the domain "academic self-perceptions" being higher in RNP students (P .05). Nursing students generally perceived their learning environment as more positive than negative. Regular students were more positive than bridging students. Students who experienced the new curriculum were more positive towards learning. The cross-sectional design and unequal gender and study level distributions may limit generalizability of the results. Longitudinal, large-scale studies with more even distributions of participant characteristics are needed.

    The development of the hydrocarbon resources of the North Sea has resulted in both offshore and onshore environmental repercussions, involving the existing physical attributes of the sea and seabed, the coastline and adjoining land. The social and economic repercussions of the industry were equally widespread. The dramatic and speedy impact of the exploration and exploitation of the northern North Sea resources in the early 1970s, on the physical resources of Scotland was quickly realised together with the concern that any environmental and social damage to the physical and social fabric should be kept to a minimum. To this end, a wide range of research and other activities by central and local government, and other interested agencies was undertaken to extend existing knowledge on the marine and terrestrial environments that might be affected by the oil and gas industry. The outcome of these activities is summarized in this paper. The topics covered include a survey of the marine ecosystems of the North Sea, the fishing industry, the impact of oil pollution on seabirds and fish stocks, the ecology of the Scottish coastline and the impact of the petroleum industry on a selection of particular sites.

Perceptions were compared between genders and 2 bachelor's programs. A total of 219 students participated in this study, drawn from the Generic Bachelor of Science in Nursing (GBSN) and the Post-Registered Nurse Bachelor of Science in Nursing (PRBSN) programs of the Shifa College of Nursing, Islamabad, Pakistan. The Dundee Ready Education Environment Measure was utilized for data collection. Descriptive statistics were used to calculate total scores, as well as means and standard deviations, and the t-test was applied for comparisons according to program and gender. The overall total mean score (119 of 200) is suggestive of more positive than negative perceptions of the educational environment. The mean score of 13 of 28 on the social self-perception subscale suggests that the social environment was felt to be 'not a nice place.' The t-test revealed more positive perceptions among students enrolled in the PRBSN program (Pnursing students. Both positive and negative perceptions were reported; the overall sense of a positive environment was present, but the social component requires immediate attention, along with other unsatisfactory components. Establishing a supportive environment conducive to competence-based learning would play an important role in bringing desirable changes to the educational environment.

    Full Text Available This paper discusses the proposed model of the collaborative virtual learning system for the introductory computer programming course which uses one of the collaborative learning techniques known as the “Think-Pair-Share”. The main objective of this study is to design a model for an online learning system that facilitates the collaborative learning activities in a virtual environment such as online communications and pair or small group discussions. In order to model the virtual learning environment, the RUP methodology has been used where it involves the data collection phase and the analysis and design phase. Fifty respondents have been randomly selected to participate in the data collection phase to investigate the students’ interest and learning styles as well as their learning preferences. The results have shown the needs for the development of online small group discussions that can be used as an alternative learning style for programming courses. The proposed design of the virtual learning system named as the Online Collaborative Learning System or OCLS is being depicted using the object-oriented models which are the use-case model and class diagram in order to show the concise processes of virtual “Think-Pair-Share” collaborative activities. The “Think-Pair-Share” collaborative learning technique that is being used in this model has been chosen because of its simplicity and relatively low-risk. This paper also presents the proposed model of the system’s architecture that will become the guidelines for the physical development of OCLS using the web-based applications.

    Biological pathways are descriptive diagrams of biological processes widely used for functional analysis of differentially expressed genes or proteins. Primary data analysis, such as quality control, normalisation, and statistical analysis, is often performed in scripting languages like R, Perl, and Python. Subsequent pathway analysis is usually performed using dedicated external applications. Workflows involving manual use of multiple environments are time consuming and error prone. Therefore, tools are needed that enable pathway analysis directly within the same scripting languages used for primary data analyses. Existing tools have limited capability in terms of available pathway content, pathway editing and visualisation options, and export file formats. Consequently, making the full-fledged pathway analysis tool PathVisio available from various scripting languages will benefit researchers. We developed PathVisioRPC, an XMLRPC interface for the pathway analysis software PathVisio. PathVisioRPC enables creating and editing biological pathways, visualising data on pathways, performing pathway statistics, and exporting results in several image formats in multiple programming environments. We demonstrate PathVisioRPC functionalities using examples in Python. Subsequently, we analyse a publicly available NCBI GEO gene expression dataset studying tumour bearing mice treated with cyclophosphamide in R. The R scripts demonstrate how calls to existing R packages for data processing and calls to PathVisioRPC can directly work together. To further support R users, we have created RPathVisio simplifying the use of PathVisioRPC in this environment. We have also created a pathway module for the microarray data analysis portal ArrayAnalysis.org that calls the PathVisioRPC interface to perform pathway analysis. This module allows users to use PathVisio functionality online without having to download and install the software and exemplifies how the PathVisioRPC interface can be

    Full Text Available This study employed a survey method to investigate the influence of library environments, user education, and user-librarian collaborations on the use of academic libraries by undergraduate students in Nigeria. 2,676 students from six universities in the South-West Nigeria responded to the questionnaire. The findings revealed that the academic libraries are less used because of the availability of alternative information systems (such as the Internet, reading-rooms in residence halls and apartments, poor library environment, inadequate user education programs, and absence of formal user-librarian collaboration programs. It is recommended that the internal and external environment of the libraries be improved, that user education programs be extended to 2 semesters, and that user-librarian collaborations be institutionalised.

    PHREEQC [1] is a widely used non-interactive open source software for speciation, batch-reactions, one-dimensional transport, and inverse geochemical caclulations. It represents the tool of choice for many researchers and practicioners for a broad set of geochemical problems, underground CO2 storage among others. Its open source nature, the flexibility to program arbitrary kinetic laws for the chemical reactions, as well as a thorough implementation of the Pitzer formalism explain its success and longevity. However, its non-interactive architecture make it cumbersome to couple PHREEQC to transport programs to achieve reactive transport simulations [2], but also to overcome the limitations of PHREEQC itself regarding the setup of large numbers of simulations - for example exploring wide ranges of conditions - and the graphical evaluation of the results. This has been the main motivation leading to the development of an interface with the high level language and environment for statistical computing and graphics GNU R [3]. The interface consists of minor modifications in PHREEQC's C source code, only affecting data I/O, plus on the R side a bunch of helper functions used to setup the simulations - basically automated manipulation of PHREEQC's input files, which are text files - and to collect and visualize the results. The most relevant subset of PHREEQC's capabilities and features are fully usable through the interface. Illustratory examples for the utility of this programmable interface were given in the framework of the research project this developement originated from: CLEAN [4], a project investigating the feasibility of enhanced gas recovery combined with CO2 storage. This interface allowed us to successfully and easily manipulate, compare and refit chemical databases, perform sensitivity analysis by combinatory variations of parameters, and all that in an environment which is both scriptable and interactive, with all results directly available for further

    System interface sets (SIS) for large, complex, non-stop, distributed systems are examined. The SIS of the Space Station Program (SSP) was selected as the focus of this study because an appropriate virtual interface specification of the SIS is believed to have the most potential to free the project from four life cycle tyrannies which are rooted in a dependance on either a proprietary or particular instance of: operating systems, data management systems, communications systems, and instruction set architectures. The static perspective of the common Ada programming support environment interface set (CAIS) and the portable common execution environment (PCEE) activities are discussed. Also, the dynamic perspective of the PCEE is addressed.

    Full Text Available Background Despite of healthy nutrition recommendations have been offered in recent decades, researches show an increasing rate of unhealthy junk food consumption among primary school children. The aim of this study was to investigate the effects of health promotion intervention on the school food buffets and the changes in nutritional behaviors of the students. Materials and Methods In this Quasi-interventional study, eight schools agreed to participate in Tabriz city, Iran. The schools were randomly selected and divided into an intervention and a control group, and a pretest was given to both groups. A four weeks interventional program was conducted in eight randomly selected schools of the city based on the socio-ecological model. A check list was designed for the assessment of food items available at the schools’ buffets, a 60-item semi-quantitative food frequency questionnaire (FFQ was used to assess the rate of food consumption and energy intake. Results evaluation and practice were analyzed using the Wilcoxon, Mann Whitney-U and Chi-square tests. Results The findings revealed reduction in the intervention group between before and after intervention with regard the range of junk food consumption, except for the sweets consumption. The number of junk foods provided in the schools buffets reduced in the intervention group. After the intervention on the intervention group significant decreases were found in the intake of energy, fat and saturated fatty acids compared to the control group (p = 0.00.   Conclusion In order to design effective school food environment promotion programs, school healthcare providers should consider multifaceted approaches.

    Change management is an important area of training in undergraduate nursing education. Successful change management in healthcare aimed at improving practices requires facilitation skills that support teams in attaining the desired change. Developing facilitation skills in nursing students requires formal educational support. A Dutch Regional Care Improvement Program based on a nationwide format of change management in healthcare was designed to act as a Powerful Learning Environment for nursing students developing competencies in facilitating change. This article has two aims: to provide comprehensive insight into the program components and to describe students' learning experiences in developing their facilitation skills. This Dutch Regional Care Improvement Program considers three aspects of a Powerful Learning Environment: self-regulated learning; problem-based learning; and complex, realistic and challenging learning tasks. These three aspects were operationalised in five distinct areas of facilitation: increasing awareness of the need for change; leadership and project management; relationship building and communication; importance of the local context; and ongoing monitoring and evaluation. Over a period of 18 months, 42 nursing students, supported by trained lecturer-coaches, took part in nine improvement teams in our Regional Care Improvement Program, executing activities in all five areas of facilitation. Based on the students' experiences, we propose refinements to various components of this program, aimed at strengthenin the learning environment. There is a need for further detailed empirical research to study the impact this kind of learning environment has on students developing facilitation competencies in healthcare improvement.

  11. Recommendations for Guidelines for Environment-Specific Magnetic-Field Measurements, Rapid Program Engineering Project #2

    Energy Technology Data Exchange (ETDEWEB)

    1997-03-11

    The purpose of this project was to document widely applicable methods for characterizing the magnetic fields in a given environment, recognizing the many sources co-existing within that space. The guidelines are designed to allow the reader to follow an efficient process to (1) plan the goals and requirements of a magnetic-field study, (2) develop a study structure and protocol, and (3) document and carry out the plan. These guidelines take the reader first through the process of developing a basic study strategy, then through planning and performing the data collection. Last, the critical factors of data management, analysis reporting, and quality assurance are discussed. The guidelines are structured to allow the researcher to develop a protocol that responds to specific site and project needs. The Research and Public Information Dissemination Program (RAPID) is based on exposure to magnetic fields and the potential health effects. Therefore, the most important focus for these magnetic-field measurement guidelines is relevance to exposure. The assumed objective of an environment-specific measurement is to characterize the environment (given a set of occupants and magnetic-field sources) so that information about the exposure of the occupants may be inferred. Ideally, the researcher seeks to obtain complete or "perfect" information about these magnetic fields, so that personal exposure might also be modeled perfectly. However, complete data collection is not feasible. In fact, it has been made more difficult as the research field has moved to expand the list of field parameters measured, increasing the cost and complexity of performing a measurement and analyzing the data. The guidelines address this issue by guiding the user to design a measurement protocol that will gather the most exposure-relevant information based on the locations of people in relation to the sources. We suggest that the "microenvironment" become the base unit of area in a study, with

    This paper presents the highlights and constraints of RT/OS and how it can be used at other places. The support of approximately 1000 VME and VXI CPUs in network-based multiprocessor systems needs a special set of programming tools and application environment which are bundled as the RT/OS Real-Time-Operating-System. Supporting the Motorola 680x0 processors and micro-controller with a development system on UNIX and MS-DOS platforms, the tool set gives the opportunity of bringing small embedded controllers as well as VME multiprocessor systems into operation. The tool set includes a cross compiler and a special version of a remote debugger, as well as application support such as downloading and configuration management. The main feature is a modular kernel with message-based task switching, using the rendezvous principle to allow easy extension. Special features of this kernel for a distributed system are networking with the Berkeley socket library supporting TCP/IP, XNS and Novell Netware, a multiprocessor system on VMEbus with the interprocessor Communication Module (IPC), a device driver library for almost every G64 I/O card using a FieldBus Interface called PDV and a X11R4 port.

    Python unique features such its interpretative, multiplatform and object oriented nature as well as being a free and open source software creates the possibility that any user connected to the internet can download the entire package into any platform, install it and immediately begin to use it. Thus Python is gaining reputation as a preferred environment for introducing students and new beginners to programming. Therefore in Africa, the Python African Tour project has been launched and we are coordinating its use in computational science. We examine here the challenges and prospects of using Python for computational physics (CP) education in developing countries (DC). Then we present our project on using Python to simulate and aid the learning of laboratory experiments illustrated here by modeling of the simple pendulum and also to visualize phenomena in physics illustrated here by demonstrating the wave motion of a particle in a varying potential. This project which is to train both the teachers and our students on CP using Python can easily be adopted in other DC.

    2011-04-01

    How do you keep a classroom of 100 undergraduates actively learning? Can students practice communication and teamwork skills in a large class? How do you boost the performance of underrepresented groups? The Student-Centered Active Learning Environment for Undergraduate Programs (SCALE-UP) Project has addressed these concerns. Because of their inclusion in a leading introductory physics textbook, project materials are used by more than 1/3 of all science, math, and engineering majors nationwide. The room design and pedagogy have been adopted at more than 100 leading institutions across the country. Physics, chemistry, math, astronomy, biology, engineering, earth sciences, and even literature classes are currently being taught this way. Educational research indicates that students should collaborate on interesting tasks and be deeply involved with the material they are studying. We promote active learning in a redesigned classroom for 100 students or more. (Of course, smaller classes can also benefit.) Class time is spent primarily on "tangibles" and "ponderables"--hands-on activities, simulations, and interesting questions. Nine students sit in three teams at round tables. Instructors circulate and engage in Socratic dialogues. The setting looks like a banquet hall, with lively interactions nearly all the time. Hundreds of hours of classroom video and audio recordings, transcripts of numerous interviews and focus groups, data from conceptual learning assessments (using widely-recognized instruments in a pretest/posttest protocol), and collected portfolios of student work are part of our rigorous assessment effort. Our findings (based on data from over 16,000 students collected over five years as well as replications at adopting sites) can be summarized as the following: 1) Female failure rate is 1/5 of previous levels, even though more is demanded of students. 2) Minority failure rate is 1/4 that seen in traditionally taught courses. 3) At-risk students are more

    This effort, sponsored by the Defense Nuclear Agency under the Radiation Environments Program, was carried out to obtain measured data for benchmarking MASH, the Monte Carlo Adjoint Code System. MASH was developed to replace the Vehicle Code System, VCS, that has been used by the Department of Defense and NATO for calculating neutron and gamma-ray radiation fields and shielding protection factors inside armored vehicles and structures from nuclear weapon radiation. Free-field data were obtained at distances of 170- and 400-meters from the APR while in-box measurements were made at 400 meters only. The box, included to obtain neutron and gamma-ray reduction factors, was a 2-meter cube configuration having 0.1016-m-thick steel walls. Calculated data were obtained using MASH by analysts from the Oak Ridge National Laboratory and Science Applications International Corporation. Calculated (C) results were compared with experimental (E) data in terms of C/E ratios. Free-field and in-box neutron kerma generally agreed within ±20%, although some C/E comparisons fell outside this range depending upon the detector against which the calculated data were compared. For those cases where the C/E ratio is marginal or unacceptable, problems in the detector systems were acknowledged to be principal cause of the discrepancy. Generally poor agreement (∼25-35%) was achieved among the C/E ratios for the free-field gamma-ray kerma at the 170- and 400-m locations while excellent (10%, or better) C/E values were obtained for the in-box conditions. The discrepancy for the free-field comparison was attributed to the failure by the analysts to include a tree line adjacent to the measurement site in the calculational geometry. C/E values for the neutron and gamma-ray reduction factors ranged from 1% to 23% depending on the detector. 4 refs., 2 figs., 14 tabs

    In April 2005 twenty civil nuclear sites in the United Kingdom became the responsibility of the Nuclear Decommissioning Authority (NDA), a new organization created by the British Government to manage the cleanup of these sites. As a key part of this transition, the NDA became the owner and manager of these sites, which formerly were owned by the site operators, British Nuclear Fuels Limited plc (BNFL) and the United Kingdom Atomic Energy Authority (UKAEA). This was one of the most significant events in the history of the United Kingdom's nuclear industry and represented a true sea change, affecting many aspects of life and business on and around these sites as well as nationally. The NDA's budget for the cleanup of the twenty sites and the management of the overall cleanup program is approximately pounds 2 Billion per annum, almost $4 Billion. It is important to note that approximately half of this amount is spent with the supply chains which serve the management and operations contractors, including pounds 500 million at Sellafield alone. Additionally, the site management and operations contractors receive most of the pounds 2 Billion through contracts between the NDA and the various site management companies. This represents a lot of government money moving through contracts between entities, which invokes procurement and contracting rules and regulations, that while not new, have not previously been this broadly applied to nuclear site cleanup activities throughout the UK. The current estimate for the total life cycle cleanup costs for all twenty civil nuclear sites is pounds 56 Billion, a figure that is likely to increase further. The first rules to mention are the European Union Procurement Guidelines, which are designed to help ensure that procurements involving government funds are conducted in an open, fair, and transparent environment. While it is difficult to argue with the intent of these rules, at least for now they are having a slowing down effect on

    The accountable care organization (ACO), one of the most promising and talked about new models of care, focuses on improving communication and care transitions by tying potential shared savings to specific clinical and financial benchmarks. An important factor in meeting these benchmarks is an ACO's ability to manage medications in an environment where medical and pharmacy care has been integrated. The program described in this article highlights the critical components of Marshfield Clinic's Drug Safety Alert Program (DSAP), which focuses on prioritizing and communicating safety issues related to medications with the goal of reducing potential adverse drug events. Once the medication safety concern is identified, it is reviewed to evaluate whether an alert warrants sending prescribers a communication that identifies individual patients or a general communication to all physicians describing the safety concern. Instead of basing its decisions regarding clinician notification about drug alerts on subjective criteria, the Marshfield Clinic's DSAP uses an internally developed scoring system. The scoring system includes criteria developed from previous drug alerts, such as level of evidence, size of population affected, severity of adverse event identified or targeted, litigation risk, available alternatives, and potential for duration of medication use. Each of the 6 criteria is assigned a weight and is scored based upon the content and severity of the alert received.  In its first 12 months, the program targeted 6 medication safety concerns involving the following medications: topiramate, glyburide, simvastatin, citalopram, pioglitazone, and lovastatin. Baseline and follow-up prescribing data were gathered on the targeted medications. Follow-up review of prescribing data demonstrated that the DSAP provided quality up-to-date safety information that led to changes in drug therapy and to decreases in potential adverse drug events. In aggregate, nearly 10,000 total

    Jackson, M.A.

    1982-01-01

    The programmer's task is often taken to be the construction of algorithms, expressed in hierarchical structures of procedures: this view underlies the majority of traditional programming languages, such as Fortran. A different view is appropriate to a wide class of problem, perhaps including some problems in High Energy Physics. The programmer's task is regarded as having three main stages: first, an explicit model is constructed of the reality with which the program is concerned; second, this model is elaborated to produce the required program outputs; third, the resulting program is transformed to run efficiently in the execution environment. The first two stages deal in network structures of sequential processes; only the third is concerned with procedure hierarchies. (orig.)

  12. Long-Term Weight Loss Effects of a Behavioral Weight Management Program: Does the Community Food Environment Matter?

    2018-01-01

    Full Text Available This study examined whether community food environments altered the longer-term effects of a nationwide behavioral weight management program on body mass index (BMI. The sample was comprised of 98,871 male weight management program participants and 15,385 female participants, as well as 461,302 and 37,192 inverse propensity-score weighted matched male and female controls. We measured the community food environment by counting the number of supermarkets, convenience stores, and fast food restaurants within a 1-mile radius around each person’s home address. We used difference-in-difference regression models with person and calendar time fixed effects to estimate MOVE! effects over time in sub-populations defined by community food environment attributes. Among men, after an initial decrease in BMI at 6 months, the effect of the program decreased over time, with BMI increasing incrementally at 12 months (0.098 kg/m2, p < 0.001, 18 months (0.069 kg/m2, p < 0.001, and 24 months (0.067 kg/m2, p < 0.001. Among women, the initial effects of the program decreased over time as well. Women had an incremental BMI change of 0.099 kg/m2 at 12 months (p < 0.05 with non-significant incremental changes at 18 months and 24 months. We found little evidence that these longer-term effects of the weight management program differed depending on the community food environment. Physiological adaptations may overwhelm environmental influences on adherence to behavioral regimens in affecting longer-term weight loss outcomes.

    Science.gov (United States)

    A request for technical collaboration between the UNEP and the US EPA resulted in the establishment of a MCRADA. The purpose of this agreement was to evaluate an air quality monitoring system (referred to as the UNEP pod) developed by the UNEP for use in environmental situations where more sophisticated monitoring instrumentation was not available. The US EPA has conducted numerous evaluations of other similar sensor pods at its Research Triangle Park, NC research campus and has trained staff as well as established research designs for such efforts. Under the terms of the MCRADA, the US EPA would operate the pod using UNEP provided operating procedures in a manner consistent with its planned intent of deployment. The US EPA would collect air quality monitoring data from the pod involving select environmental measures over a period of approximately one month. Reference monitoring data collected from collocated federal regulatory monitors would be used to establish a comparison between the two systems and thus establishment of performance characteristics. In addition, the US EPA would provide feedback information to the UNEP as to observed ease of use features of the pod that would be beneficial in its future evolution and deployment. The UNEP recently developed a multipollutant sensor pod called the UNEP Air Quality Monitoring Unit, herein simply defined as the UNEP pod (http://aqicn.org/faq/2015-10-28/unep-air-quality-monitoring-station/).

    Three projects are currently underway for the development of new coatings for the protection of materials in the space environment. These coatings are based on vacuum deposition technologies. The projects will go as far as the proof-of-concept stage when the commercial potential for the technology will be demonstrated on pilot-scale fabrication facilities in 1996. These projects are part of a subprogram to develop supporting technologies for automation and robotics technologies being developed under the Canadian Space Agency's STEAR Program, part of the Canadian Space Station Program.

    The objective was to determine baseline characteristics of pediatric residency training programs and academic departments in regard to family-friendly work environments as outlined in the Report of the Task Force on Women in Pediatrics. We conducted Web-based anonymous surveys of 147 pediatric department chairs and 203 pediatric program directors. The chair's questionnaire asked about child care, lactation facilities, family leave policies, work-life balance, and tenure and promotion policies. The program director's questionnaire asked about family leave, parenting, work-life balance, and perceptions of "family-friendliness." The response rate was 52% for program directors and 51% for chairs. Nearly 60% of chairs reported some access to child care or provided assistance locating child care; however, in half of these departments, demand almost always exceeded supply. Lactation facilities were available to breastfeeding faculty in 74% of departments, although only 57% provided access to breast pumps. A total of 78% of chairs and 90% of program directors reported written maternity leave policies with slightly fewer reporting paternity leave policies. The majority (83%) of chairs reported availability of part-time employment, whereas only 27% of program directors offered part-time residency options. Most departments offered some flexibility in promotion and tenure. Although progress has been made, change still is needed in many areas in pediatric departments and training programs, including better accessibility to quality child care; improved lactation facilities for breastfeeding mothers; clear, written parental leave policies; and flexible work schedules to accommodate changing demands of family life.

  3. Green energy. Biomass fuels and the environment

    International Nuclear Information System (INIS)

    1991-01-01

    The United Nations Environment Programme has been concerned with energy/environment issues since it was first set up after the United Nations Conference on the Human Environment held in Stockholm in 1972. In the late 1970s, UNEP compiled three comprehensive reports on the the environmental impacts of the production and use of fossil fuels, nuclear energy and renewable energy sources. In 1987 it was decided to update the volume on renewable energy since knowledge of biofuels and their effects on the environment had greatly improved. Among many innovations, Brazil's decision to embark on a major, and now successful, programme to produce ethanol from sugarcane as a substitute vehicle fuel is one of the most significant. At the same time, energy tree crops, agroforestry systems and the use of plantations for environmental improvement have become issues of key importance to sustainable development in developing countries. Biomass fuels, of course, have always been important in terms of the numbers of people who use them; the significant change during the 1980s was that the potential advantages of these fuels took on a new significance in the light of environmental degradation and related issues such as greenhouse warming. The biomass fuels began to be considered as attractive energy sources in their own right - not simply as 'last resort' fuels for developing countries with only limited energy options. While this development may solve some environmental problems, it certainly raises others - the improper utilization of biomass fuels in the past has been responsible for deforestation, desertification and the ill health of many millions of the women in developing countries who use biomass fuels in unventilated huts. These issues currently affect about half of the world population. The new UNEP study was intended to provide an up-to-date evaluation of the environmental issues raised by the use of biomass fuels, and hence to reduce or eliminate their adverse impacts while

    2014-03-01

    In the area of child maltreatment prevention, little is known about the typology of changes that individuals undergo in response to parent-training interventions. In this study, we examined the patterns of change observed in parents immediately after their completion of the Apoyo Personal y Familiar (APF, Personal and Family Support) parenting program. We identified five clusters and classified 496 parents according to two criteria: (a) the amount of pre-post changes (total or partial) as reflected in their self-reports on implicit theories, parental agency and childrearing practices, and (b) the positive, negative or mixed character of these changes. The study also included a follow-up of a subset of 95 participants intended to examine the extent to which the patterns of change identified in the first part of the study might predict the quality of the childrearing environment at home and the successful integration of the APF program into social services structures one year on. In this follow-up study, external evaluators observed families' home environments and collected the parenting program facilitators' self-reports on changes to their work environment. The evaluators found higher-quality childrearing environments and more positive appraisals of the changes to the teams' work with families in those cases where participants had experienced partial or total positive changes as a result of the APF. This approach offers insights into processes of individual change that have practical implications for the successful implementation of parenting programs in child maltreatment prevention services.

    2008-01-01

    In FY2008, the U.S. Department of Defense (DoD) initiated the Computational Research and Engineering Acquisition Tools and Environments (CREATE) program, a $360M program with a two-year planning phase and a ten-year execution phase. CREATE will develop and deploy three computational engineering tool sets for DoD acquisition programs to use to design aircraft, ships and radio-frequency antennas. The planning and execution of CREATE are based on the 'lessons learned' from case studies of large-scale computational science and engineering projects. The case studies stress the importance of a stable, close-knit development team; a focus on customer needs and requirements; verification and validation; flexible and agile planning, management, and development processes; risk management; realistic schedules and resource levels; balanced short- and long-term goals and deliverables; and stable, long-term support by the program sponsor. Since it began in FY2008, the CREATE program has built a team and project structure, developed requirements and begun validating them, identified candidate products, established initial connections with the acquisition programs, begun detailed project planning and development, and generated the initial collaboration infrastructure necessary for success by its multi-institutional, multidisciplinary teams

    2000-01-01

    To determine which, if any, characteristics should be incorporated into a select-in approach to screening personnel for long-duration spaceflight, we examined the influence of crewmember social/ demographic characteristics, personality traits, interpersonal needs, and characteristics of station physical environments on performance measures in 657 American men who spent an austral winter in Antarctica between 1963 and 1974. During screening, subjects completed a Personal History Questionnaire which obtained information on social and demographic characteristics, the Deep Freeze Opinion Survey which assessed 5 different personality traits, and the Fundamental Interpersonal Relations Orientation-Behavior (FIRO-B) Scale which measured 6 dimensions of interpersonal needs. Station environment included measures of crew size and severity of physical environment. Performance was assessed on the basis of combined peer-supervisor evaluations of overall performance, peer nominations of fellow crewmembers who made ideal winter-over candidates, and self-reported depressive symptoms. Social/demographic characteristics, personality traits, interpersonal needs, and characteristics of station environments collectively accounted for 9-17% of the variance in performance measures. The following characteristics were significant independent predictors of more than one performance measure: military service, low levels of neuroticism, extraversion and conscientiousness, and a low desire for affection from others. These results represent an important first step in the development of select-in criteria for personnel on long-duration missions in space and other extreme environments. These criteria must take into consideration the characteristics of the environment and the limitations they place on meeting needs for interpersonal relations and task performance, as well as the characteristics of the individuals and groups who live and work in these environments.

    1994-09-01

    This third volume of the Information Management Architecture for an Integrated Computing Environment for the Environmental Restoration Program--the Interim Technical Architecture (TA) (referred to throughout the remainder of this document as the ER TA)--represents a key milestone in establishing a coordinated information management environment in which information initiatives can be pursued with the confidence that redundancy and inconsistencies will be held to a minimum. This architecture is intended to be used as a reference by anyone whose responsibilities include the acquisition or development of information technology for use by the ER Program. The interim ER TA provides technical guidance at three levels. At the highest level, the technical architecture provides an overall computing philosophy or direction. At this level, the guidance does not address specific technologies or products but addresses more general concepts, such as the use of open systems, modular architectures, graphical user interfaces, and architecture-based development. At the next level, the technical architecture provides specific information technology recommendations regarding a wide variety of specific technologies. These technologies include computing hardware, operating systems, communications software, database management software, application development software, and personal productivity software, among others. These recommendations range from the adoption of specific industry or Martin Marietta Energy Systems, Inc. (Energy Systems) standards to the specification of individual products. At the third level, the architecture provides guidance regarding implementation strategies for the recommended technologies that can be applied to individual projects and to the ER Program as a whole

    Ray, R. B.

    1994-01-01

    OPMILL is a computer operating system for a Kearney and Trecker milling machine that provides a fast and easy way to program machine part manufacture with an IBM compatible PC. The program gives the machinist an "equation plotter" feature which plots any set of equations that define axis moves (up to three axes simultaneously) and converts those equations to a machine milling program that will move a cutter along a defined path. Other supported functions include: drill with peck, bolt circle, tap, mill arc, quarter circle, circle, circle 2 pass, frame, frame 2 pass, rotary frame, pocket, loop and repeat, and copy blocks. The system includes a tool manager that can handle up to 25 tools and automatically adjusts tool length for each tool. It will display all tool information and stop the milling machine at the appropriate time. Information for the program is entered via a series of menus and compiled to the Kearney and Trecker format. The program can then be loaded into the milling machine, the tool path graphically displayed, and tool change information or the program in Kearney and Trecker format viewed. The program has a complete file handling utility that allows the user to load the program into memory from the hard disk, save the program to the disk with comments, view directories, merge a program on the disk with one in memory, save a portion of a program in memory, and change directories. OPMILL was developed on an IBM PS/2 running DOS 3.3 with 1 MB of RAM. OPMILL was written for an IBM PC or compatible 8088 or 80286 machine connected via an RS-232 port to a Kearney and Trecker Data Mill 700/C Control milling machine. It requires a "D:" drive (fixed-disk or virtual), a browse or text display utility, and an EGA or better display. Users wishing to modify and recompile the source code will also need Turbo BASIC, Turbo C, and Crescent Software's QuickPak for Turbo BASIC.

    2016-01-01

    Characterization of accurate flight vehicle unsteady aerodynamics is critical for component and secondary structure vibroacoustic design. The Aerosciences Branch at the National Aeronautics and Space Administration (NASA) Marshall Space Flight Center has conducted a test at the NASA Ames Research Center (ARC) Unitary Plan Wind Tunnels (UPWT) to determine such ascent aeroacoustic environments for the Space Launch System (SLS). Surface static pressure measurements were also collected to aid in determination of local environments for venting, CFD substantiation, and calibration of the flush air data system located on the launch abort system. Additionally, this test supported a NASA Engineering and Safety Center study of alternate booster nose caps. Testing occurred during two test campaigns: August - September 2013 and December 2013 - January 2014. Four primary model configurations were tested for ascent aeroacoustic environment definition. The SLS Block 1 vehicle was represented by a 2.5% full stack model and a 4% truncated model. Preliminary Block 1B payload and manned configurations were also tested, using 2.5% full stack and 4% truncated models respectively. This test utilized the 11 x 11 foot transonic and 9 x 7 foot supersonic tunnel sections at the ARC UPWT to collect data from Mach 0.7 through 2.5 at various total angles of attack. SLS Block 1 design environments were developed primarily using these data. SLS Block 1B preliminary environments have also been prepared using these data. This paper discusses the test and analysis methodology utilized, with a focus on the unsteady data collection and processing.

    Reynolds, Lawrence P; Caton, Joel S

    2012-05-06

    The concept that developmental insults (for example, poor pre- or postnatal nutrition) can have long-term consequences on health and well-being of the offspring has been termed developmental programming. In livestock, developmental programming affects production traits, including growth, body composition, and reproduction. Although low birth weight was used as a proxy for compromised fetal development in the initial epidemiological studies, based on controlled studies using livestock and other animal models in the last two decades we now know that developmental programming can occur independently of any effects on birth weight. Studies in humans, rodents, and livestock also have confirmed the critical role of the placenta in developmental programming. In addition, the central role of epigenetic regulation in developmental programming has been confirmed. Lastly, relatively simple therapeutic/management strategies designed to 'rescue' placental development and function are being developed to minimize the effects of developmental programming on health and productivity of humans, livestock, and other mammals.

  2. Dependent-Chance Programming Models for Capital Budgeting in Fuzzy Environments

    Institute of Scientific and Technical Information of China (English)

    LIANG Rui; GAO Jinwu

    2008-01-01

    Capital budgeting is concerned with maximizing the total net profit subject to budget constraints by selecting an appropriate combination of projects. This paper presents chance maximizing models for capital budgeting with fuzzy input data and multiple conflicting objectives. When the decision maker sets a prospec-tive profit level and wants to maximize the chances of the total profit achieving the prospective profit level, a fuzzy dependent-chance programming model, a fuzzy multi-objective dependent-chance programming model, and a fuzzy goal dependent-chance programming model are used to formulate the fuzzy capital budgeting problem. A fuzzy simulation based genetic algorithm is used to solve these models. Numerical examples are provided to illustrate the effectiveness of the simulation-based genetic algorithm and the po-tential applications of these models.

    The benefits of using online exercises have been analysed in terms of distance learning, automatic assessment and self-regulated learning. In this study, we have not found a direct proportional relationship between student performance in the course exercises that use online technologies and the exam grades. We see that the average submission rate to these online exercises is not positively correlated with the exercise points. Yet, our results confirm that doing exercises along supports student learning and skill accumulation equipping them with the knowledge of programming. While the student performance in programming courses is affected by factors such as prior background in programming, cognitive skills and the quality of teaching, completing the course exercises via learning-by-doing is an indispensable part of teaching. Based on the student feedback from the course survey, the students are highly satisfied with using online technologies as part of learning.

    1991-01-01

    The assessment of the impacts of the French nuclear program on atmosphere pollution is based on a macroeconomic long term model MELODY particularly detailed for the energy sector. The French energy strategy, characterized by its nuclear program, is compared with an alternative coal strategy based on coal-fired power plants. The coal strategy would have entailed different economic performances, a different energy balance, and, consequently, a different quality of air. For instance, by 1990, carbon emissions would have been 60% higher with the coal strategy; actually, they are 27% lower today than their 1973 level. The French nuclear program resulted both in a carbon emission reduction similar to the Toronto Conference target, and in a significant improvement of economic performances. 4 refs.; 10 figs.; 1 tab

    1998-01-01

    Combinations of surface elements needed to determine the position and the posture of a robot have been investigated based on the morphological properties of each object and expressed in a tree form. Here, a way to construct an environment model using the task-directional instructing tree was introduced. Several surface elements to be used for modeling were prioritized taking consideration of the kind of tasks in the tree. This modeling with the instructing tree was found to be an effective method which allows to flexibly respond to severe environments including occlusion and specular reflexion, which often appear in nuclear installation. In addition, pseudo-contact point monitoring method was implemented into ''Takumi'', a sensor-based manipulation system developed in the previous year and the effectiveness of this system was examined through an experiment of putting a seal on a paper with the manipulator, suggesting availability in real working conditions.

    Skin barrier structure and function is essential to human health. Hitherto unrecognized functions of epidermal keratinocytes show that the skin plays an important role in adapting whole-body physiology to changing environments, including the capacity to produce a wide variety of hormones, neurotransmitters and cytokine that can potentially influence whole-body states, and quite possibly, even emotions. Skin microbiota play an integral role in the maturation and homeostatic regulation of keratinocytes and host immune networks with systemic implications. As our primary interface with the external environment, the biodiversity of skin habitats is heavily influenced by the biodiversity of the ecosystems in which we reside. Thus, factors which alter the establishment and health of the skin microbiome have the potential to predispose to not only cutaneous disease, but also other inflammatory non-communicable diseases (NCDs). Indeed, disturbances of the stratum corneum have been noted in allergic diseases (eczema and food allergy), psoriasis, rosacea, acne vulgaris and with the skin aging process. The built environment, global biodiversity losses and declining nature relatedness are contributing to erosion of diversity at a micro-ecological level, including our own microbial habitats. This emphasises the importance of ecological perspectives in overcoming the factors that drive dysbiosis and the risk of inflammatory diseases across the life course.

    A graphical user interface system was developed for the two dynamic simulation systems based on modular programming methods: MSS and DSNP. The following works were made in conjunction with the system development: (1) conversion of the module libraries of both DSNP and MSS, (2) extension of DSNP- pre-compiler, (3) graphical interface for module integration, and (4) automatic converter of simple language descriptions for DSNP, where (1) and (2) were made on an engineering work station, while the rest (3) and (4), on Macintosh HyperCard. By using the graphical interface, a user can specify the structure of a simulation model, geometrical data, initial values of variables, etc. only by handling modules as icon on the pallet fields. The use of extended DSNP pre-compiler then generates the final product of dynamic simulation program automatically. The capability and effectiveness of the system was confirmed by a sample simulation of PWR SBLOCA transient in PORV stuck open event. (author)

    Lehr, J.C.

    1993-01-01

    The Department of Energy (DOE) operates a large industrial complex located at various production, processing, testing, and research and development installations across the country. During the 40+ years of operation, this complex generated and managed waste to then-current standards. However, some of these waste management practices have subsequently been proven to be inadequate for long-term environmental protection. The Office of Environmental Restoration and Waste Management (EM) was established in 1989, when DOE's top priority changed from nuclear weapons production to environmental cleanup. The Environmental Restoration (ER) Program within EM was tasked to ensure that risks to human health and the environment posed by DOE's past operations at its nuclear facilities and sites are eliminated or reduced to prescribed, safe levels. Since its creation, the ER Program has been one of the fastest growing programs in the Department, demonstrating the Secretary's commitment to the new clean-up priority. (The 1989 budget was $400 million, while the 1993 budget is $1.8 billion.) As new technologies are developed and new management strategies implemented, the program will continue to expand. This paper describes the environmental remediation process from its early assessment phase to the final compliance effort

    Erez, Mattan

    2018-02-21

    The Dynamic, Exascale Global Address Space programming environment (DEGAS) project will develop the next generation of programming models and runtime systems to meet the challenges of Exascale computing. Our approach is to provide an efficient and scalable programming model that can be adapted to application needs through the use of dynamic runtime features and domain-specific languages for computational kernels. We address the following technical challenges: Programmability: Rich set of programming constructs based on a Hierarchical Partitioned Global Address Space (HPGAS) model, demonstrated in UPC++. Scalability: Hierarchical locality control, lightweight communication (extended GASNet), and ef- ficient synchronization mechanisms (Phasers). Performance Portability: Just-in-time specialization (SEJITS) for generating hardware-specific code and scheduling libraries for domain-specific adaptive runtimes (Habanero). Energy Efficiency: Communication-optimal code generation to optimize energy efficiency by re- ducing data movement. Resilience: Containment Domains for flexible, domain-specific resilience, using state capture mechanisms and lightweight, asynchronous recovery mechanisms. Interoperability: Runtime and language interoperability with MPI and OpenMP to encourage broad adoption.

  7. The Environment for Application Software Integration and Execution (EASIE), version 1.0. Volume 2: Program integration guide

    Jones, Kennie H.; Randall, Donald P.; Stallcup, Scott S.; Rowell, Lawrence F.

    1988-01-01

    The Environment for Application Software Integration and Execution, EASIE, provides a methodology and a set of software utility programs to ease the task of coordinating engineering design and analysis codes. EASIE was designed to meet the needs of conceptual design engineers that face the task of integrating many stand-alone engineering analysis programs. Using EASIE, programs are integrated through a relational data base management system. In volume 2, the use of a SYSTEM LIBRARY PROCESSOR is used to construct a DATA DICTIONARY describing all relations defined in the data base, and a TEMPLATE LIBRARY. A TEMPLATE is a description of all subsets of relations (including conditional selection criteria and sorting specifications) to be accessed as input or output for a given application. Together, these form the SYSTEM LIBRARY which is used to automatically produce the data base schema, FORTRAN subroutines to retrieve/store data from/to the data base, and instructions to a generic REVIEWER program providing review/modification of data for a given template. Automation of these functions eliminates much of the tedious, error prone work required by the usual approach to data base integration.

    The placenta is a transient organ found in eutherian mammals that evolved primarily to provide nutrients for the developing fetus. The placenta exchanges a wide array of nutrients, endocrine signals, cytokines and growth factors with the mother and the fetus, thereby regulating intrauterine development. Recent studies show that the placenta is not just a passive organ mediating maternal-fetal exchange. It can adapt its capacity to supply nutrients in response to intrinsic and extrinsic variations in the maternal-fetal environment. These dynamic adaptations are thought to occur to maximize fetal growth and viability at birth in the prevailing conditions in utero. However, some of these adaptations may also affect the development of individual fetal tissues, with patho-physiological consequences long after birth. Here, this review summarizes current knowledge on the causes, possible mechanisms and consequences of placental adaptive responses, with a focus on the regulation of transporter-mediated processes for nutrients. This review also highlights the emerging roles that imprinted genes and epigenetic mechanisms of gene regulation may play in placental adaptations to the maternal-fetal environment.

  11. Medium-term generation programming in competitive environments: a new optimisation approach for market equilibrium computing

    International Nuclear Information System (INIS)

    Barquin, J.; Centeno, E.; Reneses, J.

    2004-01-01

    The paper proposes a model to represent medium-term hydro-thermal operation of electrical power systems in deregulated frameworks. The model objective is to compute the oligopolistic market equilibrium point in which each utility maximises its profit, based on other firms' behaviour. This problem is not an optimisation one. The main contribution of the paper is to demonstrate that, nevertheless, under some reasonable assumptions, it can be formulated as an equivalent minimisation problem. A computer program has been coded by using the proposed approach. It is used to compute the market equilibrium of a real-size system. (author)

    Cross, James H., II

    1991-01-01

    The Graphical Representations of Algorithms, Structures, and Processes for Ada (GRASP/Ada) has successfully created and prototyped a new algorithm level graphical representation for Ada software, the Control Structure Diagram (CSD). The primary impetus for creation of the CSD was to improve the comprehension efficiency of Ada software and thus improve reliability and reduce costs. The emphasis was on the automatic generation of the CSD from Ada source code to support reverse engineering and maintenance. The CSD has the potential to replace traditional prettyprinted Ada source code. In Phase 1 of the GRASP/Ada project, the CSD graphical constructs were created and applied manually to several small Ada programs. A prototype (Version 1) was designed and implemented using FLEX and BISON running under the Virtual Memory System (VMS) on a VAX 11-780. In Phase 2, the prototype was improved and ported to the Sun 4 platform under UNIX. A user interface was designed and partially implemented. The prototype was applied successfully to numerous Ada programs ranging in size from several hundred to several thousand lines of source code. In Phase 3 of the project, the prototype was prepared for limited distribution (GRASP/Ada Version 3.0) to facilitate evaluation. The user interface was extensively reworked. The current prototype provides the capability for the user to generate CSD from Ada source code in a reverse engineering mode with a level of flexibility suitable for practical application.

    This study provides a spatial analysis of distribution and access to commercial fruit and vegetable establishments within the territory of a representative sample of public fitness facilities known as the Health Academy Program (HAP) in Belo Horizonte, Minas Gerais State, Brazil. The study evaluated commercial food establishments within a buffer area based on a radius of 1,600 meters around each of 18 randomly selected fitness facilities. Quality of access to fruits and vegetables was assessed by the Healthy Food Store Index (HFSI), consisting of the variables availability, variety, and advertising of fruits, vegetables and ultra-processed foods. The analysis was based on calculation of the Kernel intensity estimator, nearest neighbor method, and Ripley K-function. Of the 336 food establishments, 61.3% were green grocers and open-air markets, with a median HFSI of 11 (5 to 16). In only 17% of the territories, the majority of the "hot area" establishments displayed better access to healthy foods, and only three areas showed a clustering pattern. The study showed limited access to commercial establishments supplying healthy fruits and vegetables within the territory of the public fitness program.

    The healthcare environment consists of vast amounts of dynamic and unstructured information, distributed over a large number of information systems. Mobile agent technology is having an ever-growing impact on the delivery of medical information. It supports acquiring and manipulating information distributed in a large number of information systems. Moreover is suitable for the computer untrained medical stuff. But the introduction of mobile agents generates advanced threads to the sensitive healthcare information, unless the proper countermeasures are taken. By applying the role-based approach to the authorization problem, we ease the sharing of information between hospital information systems and we reduce the administering part. The different initiative of the agent's migration method, results in different methods of assigning roles to the agent.

    Stand alone nuclear power plant simulators, as well as building blocks based nuclear power simulator are available from different companies throughout the world. In this work, a review of such simulators has been explored for both types. Also a survey of the possible authoring tools for such simulators development has been performed. It is decided, in this research, to develop prototype simulator based on components building blocks. Further more, the authoring tool (Mat lab software) has been selected for programming. It has all the basic tools required for the simulator development similar to that developed by specialized companies for simulator like MMS, APROS and others. Components simulations, as well as integrated components for power plant simulation have been demonstrated. Preliminary neural network reactor model as part of a prepared neural network modules library has been used to demonstrate module order shuffling during simulation. The developed components library can be refined and extended for further development. (author)

  3. Hypothalamic neuroendocrine circuitry is programmed by maternal obesity: interaction with postnatal nutritional environment.

    Directory of Open Access Journals (Sweden)

    Hui Chen

    Full Text Available OBJECTIVE: Early life nutrition is critical for the development of hypothalamic neurons involved in energy homeostasis. We previously showed that intrauterine and early postnatal overnutrition programmed hypothalamic neurons expressing the appetite stimulator neuropeptide Y (NPY and suppressor proopiomelanocortin (POMC in offspring at weaning. However, the long-term effects of such programming and its interactions with post-weaning high-fat-diet (HFD consumption are unclear. RESEARCH DESIGN AND METHODS: Female Sprague Dawley rats were exposed to chow or HFD for 5 weeks before mating, throughout gestation and lactation. On postnatal day 1, litters were adjusted to 3/litter to induce postnatal overnutrition (vs. 12 in control. At postnatal day 20, half of the rats from each maternal group were weaned onto chow or HFD for 15 weeks. Hypothalamic appetite regulators, and fuel (glucose and lipid metabolic markers were measured. RESULTS: Offspring from obese dams gained more weight than those from lean dams independent of post-weaning diet. Maternal obesity interacted with post-weaning HFD consumption to cause greater levels of hyperphagia, adiposity, hyperlipidemia, and glucose intolerance in offspring. This was linked to increased hypothalamic NPY signaling and leptin resistance in adult offspring. Litter size reduction had a detrimental impact on insulin and adiponectin, while hypothalamic NPY and POMC mRNA expression were suppressed in the face of normal energy intake and weight gain. CONCLUSIONS: Maternal obesity, postnatal litter size reduction and post-weaning HFD consumption caused obesity via different neuroendocrine mechanism. There were strong additive effects of maternal obesity and post-weaning HFD consumption to increase the metabolic disorders in offspring.

    Full Text Available It has been well known for many years that prenatal life is not fully protected in the uterine microenvironment. But only over the last decade we have been focusing on mechanisms and modalities of maternal and foetal exposure to an impressive range of chemicals (e.g.: endocrine disruptors, physical factors (e.g.: ionizing radiations and biological agents (e.g.: viruses able to induce potentially adaptive and predictive epigenetic changes in the embryo-fetal genome, thus interfering with the programming of tissues and organs in an often irreversible way. Sometimes these epigenetic marks could be even inherited from one generation to another. This new awareness could radically transform the representation of the individual development (ontogeny and of the evolution of our species (phylogeny. This model of pathogenesis is the so-called theory of the embryo-foetal origins of adult diseases (DOHAD: Developmental Origins of Health and Diseases. This new paradigm is important not only to explain in a more exhaustive  way the embryo-foetal origins of all the above mentioned disorders and  their dramatic increase over the last decades, but also to try to effectively face this epidemiological transition. The key-term in this context is certainly primary prevention: only by reducing the maternal-foetal factors of distress and the exposure of the foetus (and of its gametes to pollutants,  it would be possible to protect the  correct programming of  cells, tissues and organs. Proceedings of the 11th International Workshop on Neonatology and Satellite Meetings · Cagliari (Italy · October 26th-31st, 2015 · From the womb to the adultGuest Editors: Vassilios Fanos (Cagliari, Italy, Michele Mussap (Genoa, Italy, Antonio Del Vecchio (Bari, Italy, Bo Sun (Shanghai, China, Dorret I.

    To provide a single open-source platform for comprehensive MR algorithm development inclusive of simulations, pulse sequence design and deployment, reconstruction, and image analysis. We integrated the "Pulseq" platform for vendor-independent pulse programming with Graphical Programming Interface (GPI), a scientific development environment based on Python. Our integrated platform, Pulseq-GPI, permits sequences to be defined visually and exported to the Pulseq file format for execution on an MR scanner. For comparison, Pulseq files using either MATLAB only ("MATLAB-Pulseq") or Python only ("Python-Pulseq") were generated. We demonstrated three fundamental sequences on a 1.5 T scanner. Execution times of the three variants of implementation were compared on two operating systems. In vitro phantom images indicate equivalence with the vendor supplied implementations and MATLAB-Pulseq. The examples demonstrated in this work illustrate the unifying capability of Pulseq-GPI. The execution times of all the three implementations were fast (a few seconds). The software is capable of user-interface based development and/or command line programming. The tool demonstrated here, Pulseq-GPI, integrates the open-source simulation, reconstruction and analysis capabilities of GPI Lab with the pulse sequence design and deployment features of Pulseq. Current and future work includes providing an ISMRMRD interface and incorporating Specific Absorption Ratio and Peripheral Nerve Stimulation computations. Copyright © 2018 Elsevier Inc.

    This report on the status of the Office of Environment's program for inactive uranium mill tailings sites is an analysis of the current status and a forecast of future activities of the Office of Environment. The termination date for receipt of information was September 30, 1980. Aerial radiological surveys and detailed ground radiological assessments of properties within the communities in the vicinity of the designated processing sites in Canonsburg, Pennsylvania, Salt Lake City, Utah, and Boise, Idaho led to the designation of an initial group of vicinity properties for remedial action. The potential health effects of the residual radioactive materials on or near these properties were estimated, and the Assistant Secretary for Environment recommended priorities for performing remedial action to the Department's Assistant Secretary for Nuclear Energy. In designating these properties and establishing recommended priorities for performing remedial action, the Office of Environment consulted with the Environmental Protection Agency, the Nuclear Regulatory Commission, representatives from the affected State and local governments, and individual property owners. After notifying the Governors of each of the affected States and the Navajo Nation of the Secretary of Energy's designation of processing sites within their areas of jurisdiction and establishment of remedial action priorities, a Sample Cooperative Agreement was developed by the Department in consultation with the Nuclear Regulatory Commission and provided to the affected States and the Navajo Nation for comments. During September 1980, a Cooperative Agreement with the Commonwealth of Pennsylvania for the designated Canonsburg processing site was executed by the Department. It is anticipated that a Cooperative Agreement between the State of Utah and the Department to perform remedial actions at the designated Salt Lake City site will be executed in the near future

    One of the main objectives of the German Federal Ministry for the Environment, within the overall concept of the Federal Government to help establish democracy and a social market economy in Eastern Europe, is to contribute to improving the safety of nuclear power plants. Safety evaluations of Soviet-type reactors in the former German Democratic Republic have given rise to findings since 1990 which resulted in qualified cooperation especially in Russia and Ukraine. These activities mainly serve to strengthen the role of supervisory authorities in the interest of nuclear safety, and to make available technical inspection systems for nuclear power plants. German experts also conducted safety analyses and radioactivity measurements in situ. The financial expenditure between 1990 and 1995 totaled approx. DM 150 million. The money was spent on some 75 different projects for which contracts were awarded to qualified German firms. All measures, from analyses to the provision of equipment to training seminars, serve the purpose of providing help towards self-help, together with an adequate transfer of know-how. (orig.) [de

  10. Offspring Hormones Reflect the Maternal Prenatal Social Environment: Potential for Foetal Programming?

    Meise, Kristine; von Engelhardt, Nikolaus; Forcada, Jaume; Hoffman, Joseph Ivan

    2016-01-01

    Females of many species adaptively program their offspring to predictable environmental conditions, a process that is often mediated by hormones. Laboratory studies have shown, for instance, that social density affects levels of maternal cortisol and testosterone, leading to fitness-relevant changes in offspring physiology and behaviour. However, the effects of social density remain poorly understood in natural populations due to the difficulty of disentangling confounding influences such as climatic variation and food availability. Colonially breeding marine mammals offer a unique opportunity to study maternal effects in response to variable colony densities under similar ecological conditions. We therefore quantified maternal and offspring hormone levels in 84 Antarctic fur seals (Arctocephalus gazella) from two closely neighbouring colonies of contrasting density. Hair samples were used as they integrate hormone levels over several weeks or months and therefore represent in utero conditions during foetal development. We found significantly higher levels of cortisol and testosterone (both P hormonally mediated maternal effects may depend more strongly on the maternal regulation of androgen rather than cortisol levels.

    Program management models have raised concerns among occupational therapists about professional standards related to clinical competence, performance review procedures, and quality improvement initiatives. This paper describes how a chart-stimulated recall (CSR) peer-review process and interview tool was revised, implemented, and evaluated as a pilot project to assess the clinical competence of occupational therapy staff at a large urban health centre in southern Ontario. Fourteen pairs (n=28) of occupational therapists representing various practice areas participated in this project. Half served as peer assessors and half as interviewees. Peer assessors conducted an independent chart review followed by a one-hour personal interview with a peer partner to discuss clinical management issues related to the client cases. Each interviewer rated his or her partner's clinical competence in eight areas of performance using a 7-point Likert scale. Results indicated that the CSR tool could discriminate among occupational therapists in terms of overall levels of clinical competence and also identify specific areas of concern that could be targeted for professional development. Feedback from participants was positive. The CSR tool was found to be useful for assessing clinical competence of occupational therapists in this large health centre as a quality improvement initiative within that discipline group. Further research is needed to establish the reliability and validity of the CSR tool.

    2013-06-01

    To identify the most and least commonly cited security management messages that nongovernmental organizations (NGOs) are communicating to their field staff, to determine the types of documentation that NGOs most often use to communicate key security messages, and to distinguish the points of commonality and divergence across organizations in the content of key security messages. The authors undertook a systematic review of available security policies, manuals, and training materials from 20 international humanitarian NGOs using the InterAction Minimum Operating Security Standards as the basis for a review framework. The most commonly cited standards include analytical security issues such as threat and risk assessment processes and guidance on acceptance, protection, and deterrence approaches. Among the least commonly cited standards were considering security threats to national staff during staffing decision processes, incorporating security awareness into job descriptions, and ensuring that national staff security issues are addressed in trainings. NGO staff receive security-related messages through multiple document types, but only 12 of the 20 organizations have a distinct security policy document. Points of convergence across organizations in the content of commonly cited standards were found in many areas, but differences in security risk and threat assessment guidance may undermine communication between aid workers about changes in local security environments. Although the humanitarian community has experienced significant progress in the development of practical staff security guidance during the past 10 years, gaps remain that can hinder efforts to garner needed resources, clarify security responsibilities, and ensure that the distinct needs of national staff are recognized and addressed.

    1977-07-01

    Racial, sexual, and ethnic discrimination, it is contended, creates as great a crisis in the environment as the threat of nuclear war since it also threatens social survival. Individual freedom, human dignity and socio-political equality are resources vital for the survival of Americans; White racism deprives Blacks and other minorities' members of these essentials for humane living. Survival today depends on Renewal, for which nothing is more decisive than mobility of talent. Much has been accomplished recently in bringing about the participation of minorities' members in higher education but data are presented which indicate that, in terms of income, minorities' members tend to be discriminated against greatest as they increase their education. An 8-point program is presented to achieve equity and equality in and through education.

    1991-06-01

    A brief description is given of the PASC-3 (Petten-AMPX-SCALE) Reactor Physics code system and associated UNIPASC work environment. The PASC-3 code system is used for criticality and reactor calculations and consists of a selection from the Oak Ridge National Laboratory AMPX-SCALE-3 code collection complemented with a number of additional codes and nuclear data bases. The original codes have been adapted to run under the UNIX operating system. The recommended nuclear data base is a complete 219 group cross section library derived from JEF-1 of which some benchmark results are presented. By the addition of the UNIPASC work environment the usage of the code system is greatly simplified. Complex chains of programs can easily be coupled together to form a single job. In addition, the model parameters can be represented by variables instead of literal values which enhances the readability and may improve the integrity of the code inputs.

    The basic goal in all environmental data analysis is to characterize the value of some parameter in a portion of the environment over some period of time to a stated degree of accuracy from a limited number of data points. More reliability in the results can be acquired if a proper statistical treatment of the data including estimates of precision, frequency distribution analysis and group comparisons, is performed as part of an environmental surveillance program. The main objective of this paper is to describe the procedures adopted for performing the analysis and statistical treatment of the data obtained in the Environmental Monitoring Program of CDTN during the period of 1993 to 1995. In this study, the results of total alpha and beta concentrations in airborne particulates and surface water samples are considered. In this case, the statistical treatment involved the variability estimation and frequency distribution analysis. Time series analysis of the results is carried out through sequential graphics, which give information about the long-term behavior of the variables. (author) work. (author)

    This study was conducted to evaluate the effectiveness of a mother/infant-toddler health program developed to enhance parenting knowledge, behavior and confidence in low income mothers and home environment. A one-group pretest-posttest quasi-experimental design was used. Sixty-nine dyads of mothers and infant-toddlers (aged 0-36 months) were provided with weekly intervention for seven session. Each session consisted of three parts; first, educating to increase integrated knowledge related to the development of the infant/toddler including nutrition, first aid and home environment; second, counseling to share parenting experience among the mothers and to increase their nurturing confidence; third, playing with the infant/toddler to facilitate attachment-based parenting behavior for the mothers. Following the programs, there were significant increases in parenting knowledge on nutrition and first aid. A significant improvement was found in attachment-based parenting behavior, but not in home safety practice. Nurturing confidence was not significantly increased. The program led to more positive home environment for infant/toddler's health and development. The findings provide evidence for mother-infant/toddler health program to improve parenting knowledge, attachment-based parenting behavior and better home environment in low income mothers. Study of the long term effectiveness of this program is recommended for future research.

    The Advanced Distributed Simulation (ADS) Synthetic Environments Program seeks to create robust virtual worlds from operational terrain and environmental data sources of sufficient fidelity and currency to interact with the real world. While some applications can be met by direct exploitation of standard digital terrain data, more demanding applications -- particularly those support operations 'close to the ground' -- are well-served by emerging capabilities for 'value-adding' by the user working with controlled imagery. For users to rigorously refine and exploit controlled imagery within functionally different workstations they must have a shared framework to allow interoperability within and between these environments in terms of passing image and object coordinates and other information using a variety of validated sensor models. The Synthetic Environments Program is now being expanded to address rapid construction of virtual worlds with research initiatives in digital mapping, softcopy workstations, and cartographic image understanding. The Synthetic Environments Program is also participating in a joint initiative for a sensor model applications programer's interface (API) to ensure that a common controlled imagery exploitation framework is available to all researchers, developers and users. This presentation provides an introduction to ADS and the associated requirements for synthetic environments to support synthetic theaters of war. It provides a technical rationale for exploring applications of image understanding technology to automated cartography in support of ADS and related programs benefitting from automated analysis of mapping, earth resources and reconnaissance imagery. And it provides an overview and status of the joint initiative for a sensor model API.

    Throughout the 1970s and early 1980s, the U.S. Nuclear Regulatory Commission's (NRC's) thermal-hydraulic research program enjoyed ample funding, sponsored extensive experimental and analytical development programs, and attracted worldwide expertise. With the completion of the major experimental programs and with the promulgation of the revised emergency core-cooling system rule, both the funding and prominence of thermal-hydraulic research at the NRC have declined in recent years. This has led justifiably to the concern by some that the program may no longer have the minimal elements needed to maintain both expertise and world-class status. The purpose of this article is to describe the NRC's current thermal-hydraulic research program and to show how this program ensures maintenance of a viable, robust research effort and retention of needed expertise and international leadership

    Okita, Yuji; Hayase, Kenichi; Oba, Kyoko; Fudano, Jun

    For most modern corporations, engineering is an essential element. While the public increasingly demands social responsibility in business activities, the importance of the interweaving relationship between business ethics and engineering ethics has been recognized. In this paper, firstly the change in the business environment is overviewed. Then, a new concept for designing and implementing a business ethics program, named the EAB (Ethics Across the Business) approach, is proposed. The EAB approach is highly adaptable for engineering-oriented corporations in their business ethics program activities because it derives from a process approach which has been much used by many companies to perform such activities as quality assurance and environment management. Finally, a newly developed method to monitor employee consciousness in terms of engineering ethics is introduced together with trial results.

    1991-01-01

    Field studies were conducted by MCC to determine areas of research of mutual interest to MCC and JSC. NASA personnel from the Information Systems Directorate and research faculty from UHCL/RICIS visited MCC in Austin, Texas to examine tools and applications under development in the MCC Software Technology Program. MCC personnel presented workshops in hypermedia, design knowledge capture, and design recovery on site at JSC for ISD personnel. The following programs were installed on workstations in the Software Technology Lab, NASA/JSC: (1) GERM (Graphic Entity Relations Modeler); (2) gIBIS (Graphic Issues Based Information System); and (3) DESIRE (Design Recovery tool). These applications were made available to NASA for inspection and evaluation. Programs developed in the MCC Software Technology Program run on the SUN workstation. The programs do not require special configuration, but they will require larger than usual amounts of disk space and RAM to operate properly.

  15. Terrestrial service environments for selected geographic locations. Final report. [1965--1974 data; to define solar array environment to aid in encapsulation program

    1976-06-24

    This report contains results obtained from analyses of climatic, precipitation, air pollution, and other environmental data for the years 1965 to 1974 at nine widely different geographic locations in the United States (Albuquerque, N.M.; Bismarck, N.D.; Boston, Mass.; Brownsville, TX.; Cleveland, OH; Fairbanks, AK; Los Angeles, CA; Miami, FL; and Phoenix, AZ). In addition to descriptive and diurnal statistics for 24 individual climatic variables, ''environmental cell'' statistics were computed to obtain the frequencies, durations, and transitions for the simultaneous occurrence of various combinations of environmental variables. Results are presented for the simultaneous occurrence of specific levels of air temperature, relative humidity, wind speed, and insolation, in addition to representative results obtained for other combinations of variables. The results characterize the environmental conditions to which terrestrial solar arrays would be exposed over a 20-year lifetime, and serve to identify environmental factors and levels that can be used in testing candidate encapsulation materials and systems for such terrestrial exposures. An innovative methodology was applied to obtain these results for combinations of environmental variables. Because of its generality and demonstrated feasibility, it is concluded that the methodology also has broad applications to other testing programs.

    Full Text Available The aim of this research was to determine the swimming program effects on the gross motor function, mental adjustment to the aquatic environment and the ability to move in the water and swim in children with cerebral palsy. The sample consisted of seven children (4 boys and 3 girls with spastic cerebral palsy and an average age of 9y 5mo ± 1y 3 mo. The swimming program lasted 6 weeks, with two swimming sessions per week. Each session lasted 45 minutes. The swimming program included the application of the Halliwick Method and swimming exercises which are used in a healthy population. The GMFM test was used for the assessment of gross motor functions. The WOTA2 test was applied to assess mental adjustment and swimming skills. The Wilcoxon matched pairs test was used to determine the statistically significant differences between the initial and final measuring. The results have indicated that there was statistically significant differences in the E dimension (p=0.04 and the total score T (p=0.03 of the GMFM test, then for mental adjustment to the aquatic environment WMA (p=0.02, ability to move in water andswimming skills WSW (p=0.03 and the overall result WTO (p=0.02 of the WOTA2 test. The applied swimming program had a statistically significant effect on the improvement in walking, running and jumping as well as the overall gross motor functions of children with cerebral palsy. The applied program also contributed to a statistically significant influence on the increase in mental adjustment to the aquatic environment and the ability to move in water and swim.

    Research has demonstrated a significant positive association between frequent family meals and children's dietary intake; however, the promotion of healthful family meals has not been rigorously tested for key food environment and nutrition-related behavioral outcomes in a randomized trial. To describe family home food environment and nutrition-related parent and child personal and behavioral outcomes of the Healthy Home Offerings via the Mealtime Environment Plus program, the first rigorously tested family meals intervention targeting childhood obesity prevention. Randomized controlled trial. Baseline, postintervention (12 months, 93% retention), and follow-up (21 months, 89% retention) data (surveys and dietary recalls) were collected. Children aged 8 to 12 years (N=160) and their parents were randomized to intervention (n=81) or control (n=79) groups. The intervention included five parent goal-setting calls and 10 monthly sessions delivered to families in community settings that focused on experiential nutrition activities and education, meal planning, cooking skill development, and reducing screen time. Family home food environment outcomes and nutrition-related child and parent personal and behavioral outcomes. Analyses used generalized linear mixed models. Primary comparisons were contrasts between intervention and control groups at postintervention and follow-up, with adjustments for child age and parent education. Compared with control parents, intervention parents showed greater improvement over time in scores of self-efficacy for identifying appropriate portion sizes, with significant differences in adjusted means at both post-intervention (P=0.002) and follow-up (P=0.01). Intervention children were less likely to consume at least one sugar-sweetened beverage daily at post-intervention than control children (P=0.04).

    2005-07-01

    The impact of a bullying and violence prevention program on education attainment was studied in five elementary schools (K-5), over a 5-year period. A multiple baseline design was used and academic attainment test scores of 1,106 students were monitored before and after the introduction of the program across the school district. This sample was contrasted with an equivalent control sample of 1,100 students from the school district who attended schools that did not join the program. Program participation was associated with pronounced improvements in the students' achievement test scores. Notable reductions in the scores of those students who left schools with active programs were also observed. This simple, low-cost anti-violence intervention, involves all those who work in schools, not just students. It appears to significantly benefit educational performance of children in the participating elementary schools. The program focuses attention on the interaction between the bully, victim and audience of bystanders who are seen as pivotal in either promoting or ameliorating violence. Buy in to the philosophy by teachers & administration is high, because the format allows each school to create materials with its own personal stamp, and since there is no classroom curriculum add on, the burden to teachers is vastly reduced. Psychiatrists who work with schools could easily assist a school to put the program in place as part of their consultation work.

    The aim was to assess options and cost of reducing emissions of greenhouse gases (with emphasis on carbon dioxide) from human activity in Zimbabwe. A brief description of the country's economy and energy sector, policy and pricing and regulations is given and substantial data related to the country's economy, technology, energy consumption, emission and fuel prices are presented. The energy demand in households and for other sectors in Zimbabwe are assessed, and documented in the case of the former. The reference scenarios on energy demand and supply assess greenhouse gas emissions under conditions whereby the present economic growth trends predominate. Energy efficiency improvements are discussed. Abatement technology options are stated as afforestation for carbon sequestration, more efficient coal-fired industrial boilers, extended use of hydroelectricity, prepayment electric meters, minimum tillage, optimization of coal-fired tobacco barns, industrial power factor correction equipment, domestic biogas digesters, solar water heating systems, time switches in electric geysers, optimization of industrial furnaces, photovoltaic water pumps, production of ammonia from coal for fertilizing purposes, and recovery of coke oven gases for use in thermal power generation.

    2017-10-01

    This study follows the humanitarian forensic programs in Cyprus and Kosovo over a ten-year period with an emphasis on the role of local capacity building. It begins by providing an in-depth historical account of forensic activities, followed by a comparison of the rate of excavations, exhumations and identifications. Through this analysis, a repeated pattern emerges whereby forensic activities in Kosovo start with a surge in values, which drop drastically in the first few years of operations, followed by a steadily declining productivity curve. By contrast, in Cyprus, activities begin modestly, with lower values allowing for some modest growth. Close observation of the two programs provides indications as to the factors that may influence the development of forensic programs as well as the elements that need to be set in place to create an environment conducive to greater sustainability through local ownership and responsibility.

  4. The I.A.G./A.I.G. SEDIBUD (Sediment Budgets in Cold Environments) Program (2005 - 2017): Key activities and outcomes

    2017-04-01

    Amplified climate change and ecological sensitivity of high-latitude and high-altitude cold climate environments has been highlighted as a key global environmental issue. Projected climate change in largely undisturbed cold regions is expected to alter melt-season duration and intensity, along with the number of extreme rainfall events, total annual precipitation and the balance between snowfall and rainfall. Similarly, changes to the thermal balance are expected to reduce the extent of permafrost and seasonal ground frost and increase active-layer depths. These combined effects will undoubtedly change Earth surface environments in cold regions and will alter the fluxes of sediments, solutes and nutrients. However, the absence of quantitative data and coordinated analysis to understand the sensitivity of the Earth surface environment are acute in cold regions. Contemporary cold climate environments generally provide the opportunity to identify solute and sedimentary systems where anthropogenic impacts are still less important than the effects of climate change. Accordingly, it is still possible to develop a library of baseline fluvial yields and sedimentary budgets before the natural environment is completely transformed. The SEDIBUD (Sediment Budgets in Cold Environments) Program, building on the European Science Foundation (ESF) Network SEDIFLUX (Sedimentary Source-to-Sink Fluxes in Cold Environments, since 2004) was formed in 2005 as a new Program (Working Group) of the International Association of Geomorphologists (I.A.G./A.I.G.) to address this still existing key knowledge gap. SEDIBUD (2005-2017) has currently about 400 members worldwide and the Steering Committee of this international program is composed of eleven scientists from ten different countries. The central research question of this global program is to: Assess and model the contemporary sedimentary fluxes in cold climates, with emphasis on both particulate and dissolved components.

    Full Text Available This scientific article deals with the integral estimate of the effectiveness of performance of indices of the state target programs for protection of the natural environment in Ukraine, namely – the subject of the research is quantitative indices of the State target program “Forests of Ukraine” for 2010–2015 and their estimate. Methodology. The methodological basis of the study is the system of indices for the estimate of effectiveness and performance of the state target programs for the protection of the natural environment that include the following indices (indicators: an integrated index of financing the program actions and indicators of co-financing. The author applies integrated indicator of financing the program tasks and actions to assess the actual level of financing the program from various sources through the entire period of the program implementation and to carry out a comparative analysis of financial support for various programs implemented at the expense of the budgetary funds and other sources. The author uses indicator of co-financing for calculating the ratio of actual and planned indicators of the attraction of the funds from other sources (public borrowings, extrabudgetary funds per 1 UAH of the budget funds. Results. Proceeding from the analysis of quantitative indices of the State target program “Forests of Ukraine” for 2010–2015, it was established that for all 5 years of activity, the planned level of budget financing of the Program has not been achieved. In particular, in 2010–2011, operations and tasks of the Program had been financed from the budget funds by 77% and in 2014–2015 by 33% and 27% respectively. During the entire period of the Program implementation, the average annual rate of actual financing from all sources attained 147%, including 53% from the state budget and 206% from other sources of financing. The author has proved that the said indices of the performance of the Program

    The move toward competency-based education will require medical schools and postgraduate training programs to restructure learning environments to motivate trainees to take personal ownership for learning. This qualitative study explores how medical students select and implement study strategies while enrolled in a unique, nontraditional program that emphasizes reflection on performance and competence rather than relying on high-stakes examinations or grades to motivate students to learn and excel. Fourteen first-year medical students volunteered to participate in three, 45-minute interviews (42 overall) scheduled three months apart during 2013-2014. Two medical educators used structured interview guides to solicit students' previous assessment experiences, preferred learning strategies, and performance monitoring processes. Interviews were digitally recorded and transcribed verbatim. Participants confirmed accuracy of transcripts. Researchers independently read transcripts and met regularly to discuss transcripts and judge when themes achieved saturation. Medical students can adopt an assessment for learning mind-set with faculty guidance and implement appropriate study strategies for mastery-learning demands. Though students developed new strategies at different rates during the year, they all eventually identified study and performance monitoring strategies to meet learning needs. Students who had diverse learning experiences in college embraced mastery-based study strategies sooner than peers after recognizing that the learning environment did not reward performance-based strategies. Medical students can take ownership for their learning and implement specific strategies to regulate behavior when learning environments contain building blocks emphasized in self-determination theory. Findings should generalize to educational programs seeking strategies to design learning environments that promote self-regulated learning.

    The aim of the study was to determine the association between dietary outcomes and the neighbourhood food environment (street network distance from home to stores) and consumer food environment (Nutrition Environment Measurement Survey-Stores (NEMS-S) audit). The neighbourhood food environment was captured by creating 0?5-mile and 1-mile network distance (street distance) around each participant’s home and the nearest food venue (convenience store, grocery store, supermarket, farmers’ market and produce stand). The consumer food environment was captured by conducting NEMS-S in all grocery stores/supermarkets within 0?5 and 1 mile of participants’ homes. Fayette County, KY, USA. Supplemental Nutrition Assessment Program (SNAP) participants, n 147. SNAP participants who lived within 0?5 mile of at least one farmers’ market/produce stand had higher odds of consuming one serving or more of vegetables (OR56?92; 95% CI 4?09, 11?69), five servings or more of grains (OR51?76; 95% CI 1?01, 3?05) and one serving or more of milk (OR53?79; 95% CI 2?14, 6?71) on a daily basis. SNAP participants who lived within 0?5 mile of stores receiving a high score on the NEMS-S audit reported higher odds of consuming at least one serving of vegetables daily (OR53?07; 95% CI 1?78, 5?31). Taken together, both the neighbourhood food environment and the consumer food environment are associated with a healthy dietary intake among SNAP participants.

    Psi4NumPy demonstrates the use of efficient computational kernels from the open-source Psi4 program through the popular NumPy library for linear algebra in Python to facilitate the rapid development of clear, understandable Python computer code for new quantum chemical methods, while maintaining a relatively low execution time. Using these tools, reference implementations have been created for a number of methods, including self-consistent field (SCF), SCF response, many-body perturbation theory, coupled-cluster theory, configuration interaction, and symmetry-adapted perturbation theory. Furthermore, several reference codes have been integrated into Jupyter notebooks, allowing background, underlying theory, and formula information to be associated with the implementation. Psi4NumPy tools and associated reference implementations can lower the barrier for future development of quantum chemistry methods. These implementations also demonstrate the power of the hybrid C++/Python programming approach employed by the Psi4 program.

    The Mental Health Action Checklist for a Better Workplace Environment (MHACL) is a tool for a worker participatory approach to improve work environments for worker mental health. The present study investigated the effects of an organizational intervention using the MHACL on reducing job stressors and the psychological distress of workers of a manufacturing enterprise in Japan with a controlled study design. Nine of 45 departments participated in a work environment improvement program, including planning workshops, implementation and monitoring, between July and December 2005 (intervention group, n=321). The remaining 36 departments served as the control group (n=750). Outcomes (job stressors, worksite support, psychological distress, etc.), measured using the Brief Job Stress Questionnaire, as well as sick leave days taken from the company record, were recorded before and six months after the program for both groups. Among women, skill underutilization, supervisor and coworker support, psychological distress, and job satisfaction changed more favorably in the intervention group than in the control group (pparticipation in the planning workshops and among departments with a 50% or higher rate of implemented vs. planned actions. A worker participatory organizational intervention using the MHACL seems effective for promoting mental health among Japanese white-collar women.

    Alberta Environment Water Management Operations (WMO) owns and operates 46 dams and 800 kilometres of canals in Alberta. The WMO consists of 120 staff and several contract operators to take care of this infrastructure. Most of the infrastructure supplies water for irrigation use, which adds 5 billion dollars to the provincial economy annually. Other water uses include stock watering, domestic use, municipal use, recreational use and habitat. Alberta Environment's weir safety program was also discussed along with options for rehabilitation to improve public safety. A case study of Calgary's Weir Dam on the Bow River was highlighted. A brief history of the dam was offered and safety programs around provincially-owned weirs were discussed. Photographs were included to illustrate some of the additional safety measures at the Calgary weir, such as suspended safety buoys upstream of the boom directing paddlers to the portage trail, and signage on the river that can be activated when the boom is out. Typical river users on the Calgary Bow River and safety history at the Calgary Weir were discussed along with other topics such as the Calgary Bow River weir project criteria; project design progress; pre-feasibility options; scale modelling; final design analysis; construction funding; and proposed changes to the safety program for the new weir configuration. figs.

    A plethora of observational evidence exists concerning the impact of management and leadership on workforce, work environment, and care quality. Yet, no randomised controlled trial has been conducted to test the effectiveness of leadership and management interventions in aged care. An innovative aged care clinical leadership program (Clinical Leadership in Aged Care--CLiAC) was developed to improve managers' leadership capacities to support the delivery of quality care in Australia. This paper describes the study design of the cluster randomised controlled trial testing the effectiveness of the program. Twenty-four residential and community aged care sites were recruited as managers at each site agreed in writing to participate in the study and ensure that leaders allocated to the control arm would not be offered the intervention program. Sites undergoing major managerial or structural changes were excluded. The 24 sites were randomly allocated to receive the CLiAC program (intervention) or usual care (control), stratified by type (residential vs. community, six each for each arm). Treatment allocation was masked to assessors and staff of all participating sites. The objective is to establish the effectiveness of the CLiAC program in improving work environment, workforce retention, as well as care safety and quality, when compared to usual care. The primary outcomes are measures of work environment, care quality and safety, and staff turnover rates. Secondary outcomes include manager leadership capacity, staff absenteeism, intention to leave, stress levels, and job satisfaction. Differences between intervention and control groups will be analysed by researchers blinded to treatment allocation using linear regression of individual results adjusted for stratification and clustering by site (primary analysis), and additionally for baseline values and potential confounders (secondary analysis). Outcomes measured at the site level will be compared by cluster

  16. FISSION 2120: a program for assessing the need for engineered safety feature grade air cleaning systems in post accident environments

    International Nuclear Information System (INIS)

    Martin, G. Jr.; Michlewicz, D.; Thomas, J.

    1979-01-01

    A computer program FISSION 2120, has been developed to evaluate the need for various engineered Safety Feature grade air cleaning systems to mitigate radiation exposures resulting from accidential releases of radioactivity. Those systems which are generally investigated include containment sprays with chemical additives, containment fan coolers with charcoal filters, and negative pressure maintenance systems for double barrier containments with either one-pass filtration or recirculation with filtration. The program can also be used to calculate the radiation doses to control room personnel. This type of analysis is directed towards the various protection aspects of the emergency ventilation system and involves the modeling of the radiological source terms and the atmospheric transport of the radioactive releases. The modeling is enhanced by the inherent capability of the program to accommodate simultaneous release of activity from several sources and to perform a dose evaluation for a wide range of the design characteristics of control room emergency air filtration systems. Use of the program has resulted in considerable savings in the time required to perform such analyses and in the selection of the most cost-effective Engineered Safety Features

    Proper establishment of the placenta is important for fetal survival; however, placental adaptations to inadequate maternal nutrition or other stressors are imperative for fetal growth to be optimal. The effects of maternal nutritional status and activity level on placental vascular function and uteroplacental blood flows are important to understand as improper placental function leads to reduced growth of the fetus. In environments where fetal growth can be compromised, potential therapeutics may augment placental function and delivery of nutrients to improve offspring performance during postnatal life. Factors that could enhance placental function include supplementation of specific nutrients, such as protein, hormone supplements, such as indolamines, and increased activity levels of the dam. To understand the mechanism of how the maternal environment can impact uterine or umbilical blood flows, assessment of placental vascular reactivity has been studied in several large animal models. As we begin to understand how the maternal environment impacts uterine and umbilical blood flows and other uteroplacental hemodynamic parameters, development of management methods and therapeutics for proper fetal growth can be achieved.

    The Strategic Technologies in Automation and Robotics (STEAR) program is managing a number of development contracts to improve the protection of spacecraft materials from the Low Earth Orbit (LEO) space environment. The project is structured in two phases over a 3 to 4 year period with a budget of 3 to 4 million dollars. Phase 1 is designed to demonstrate the technical feasibility and commercial potential of a coating/substrate system and its associated application process. The objective is to demonstrate a prototype fabrication capability using a full scale component of a commercially viable process for the protection of materials and surface finishes from the LEO space environment, and to demonstrate compliance with a set of performance requirements. Only phase 1 will be discussed in this paper.

    The object-oriented design strategy as both a problem decomposition and system development paradigm has made impressive inroads into the various areas of the computing sciences. Substantial development productivity improvements have been demonstrated in areas ranging from artificial intelligence to user interface design. However, there has been very little progress in the formal characterization of these productivity improvements and in the identification of the underlying cognitive mechanisms. The development and validation of models and metrics of this sort require large amounts of systematically-gathered structural and productivity data. There has, however, been a notable lack of systematically-gathered information on these development environments. A large part of this problem is attributable to the lack of a systematic programming environment evaluation methodology that is appropriate to the evaluation of object-oriented systems.

    Highlights: • Stochastic energy management of retailer under smart grid environment is proposed. • Optimal selling price is determined in the smart grid environment. • Fixed, time-of-use and real-time pricing are determined for selling to customers. • Charge/discharge of ESS is determined to increase the expected profit of retailer. • Demand response program is proposed to increase the expected profit of retailer. - Abstract: In this paper, bilateral contracting and selling price determination problems for an electricity retailer in the smart grid environment under uncertainties have been considered. Multiple energy procurement sources containing pool market (PM), bilateral contracts (BCs), distributed generation (DG) units, renewable energy sources (photovoltaic (PV) system and wind turbine (WT)) and energy storage system (ESS) as well as demand response program (DRP) as virtual generation unit are considered. The scenario-based stochastic framework is used for uncertainty modeling of pool market prices, client group demand and variable climate condition containing temperature, irradiation and wind speed. In the proposed model, the selling price is determined and compared by the retailer in the smart grid in three cases containing fixed pricing, time-of-use (TOU) pricing and real-time pricing (RTP). It is shown that the selling price determination based on RTP by the retailer leads to higher expected profit. Furthermore, demand response program (DRP) has been implemented to flatten the load profile to minimize the cost for end-user customers as well as increasing the retailer profit. To validate the proposed model, three case studies are used and the results are compared.

    2013-01-01

    Full Text Available In accord with the practical engineering design conditions, a nonlinear programming model is constructed for maximizing the fatigue life of V-belt drive in which some polymorphic uncertainties are incorporated. For a given satisfaction level and a confidence level, an equivalent formulation of this uncertain optimization model is obtained where only interval parameters are involved. Based on the concepts of maximal and minimal range inequalities for describing interval inequality, the interval parameter model is decomposed into two standard nonlinear programming problems, and an algorithm, called two-step based sampling algorithm, is developed to find an interval optimal solution for the original problem. Case study is employed to demonstrate the validity and practicability of the constructed model and the algorithm.

    The goal of this ongoing comprehensive osteoporosis disease management initiative is to provide the adult primary care physicians' (PCPs) offices with a program enabling them to systematically identify and manage their population for osteoporosis. For over six years, Hill Physicians Medical Group (Hill Physicians) has implemented multiple strategies to develop a best practice for identifying and treating members who were candidates for osteoporosis therapy. Numerous tools were used to support this disease management effort, including: evidence-based clinical practice guidelines, patient education sessions, the Simple Calculated Osteoporosis Risk Estimation (SCORE) questionnaire tool, member specific reports for PCPs, targeted member mailings, office-based Peripheral Instantaneous X-ray Imaging (PIXI) test and counseling, dual x-ray absorptiometry (DEXA) scan guidelines, and web-based Electronic Simple Calculated Osteoporosis Risk Estimation (eSCORE) questionnaire tools. Hill Physicians tabulated results for patients who completed 2649 SCORE tests, screened 978 patients with PIXI tests, and identified 338 osteopenic and 124 osteoporotic patients. The preliminary results of this unique six-year ongoing educational initiative are slow but promising. New physician offices express interest in participating and those offices that have participated in the program continue to screen for osteoporosis. Hill Physicians' message is consistent and is communicated to the physicians repeatedly in different ways in accordance with the principles of educational outreach. Physicians who have conducted the program have positive feedback from their patients and office staff and have begun to communicate their experience to their peers.

    The concept of the “risk environment” – defined as the “space … [where] factors exogenous to the individual interact to increase the chances of HIV transmission” – draws together the disciplines of public health and geography. Researchers have increasingly turned to geographic methods to quantify dimensions of the risk environment that are both structural and spatial (e.g., local poverty rates). The scientific power of the intersection between public health and geography, however, has yet to be fully mined. In particular, research on the risk environment has rarely applied geographic methods to create neighbourhood-based measures of syringe exchange programs (SEPs) or of drug-related law enforcement activities, despite the fact that these interventions are widely conceptualized as structural and spatial in nature and are two of the most well-established dimensions of the risk environment. To strengthen research on the risk environment, this paper presents a way of using geographic methods to create neighbourhood-based measures of (1) access to SEP sites and (2) exposure to drug-related arrests, and then applies these methods to one setting (New York City). NYC-based results identified substantial cross-neighbourhood variation in SEP site access and in exposure to drug-related arrest rates (even within the subset of neighbourhoods nominally experiencing the same drug-related police strategy). These geographic measures – grounded as they are in conceptualizations of SEPs and drug-related law enforcement strategies – can help develop new arenas of inquiry regarding the impact of these two dimensions of the risk environment on injectors’ health, including exploring whether and how neighbourhood-level access to SEP sites and exposure to drug-related arrests shape a range of outcomes among local injectors.

    Xiang, Lin

    This is a collective case study seeking to develop detailed descriptions of how programming an agent-based simulation influences a group of 8 th grade students' model-based inquiry (MBI) by examining students' agent-based programmable modeling (ABPM) processes and the learning outcomes. The context of the present study was a biology unit on natural selection implemented in a charter school of a major California city during spring semester of 2009. Eight 8th grade students, two boys and six girls, participated in this study. All of them were low socioeconomic status (SES). English was a second language for all of them, but they had been identified as fluent English speakers at least a year before the study. None of them had learned either natural selection or programming before the study. The study spanned over 7 weeks and was comprised of two study phases. In phase one the subject students learned natural selection in science classroom and how to do programming in NetLogo, an ABPM tool, in a computer lab; in phase two, the subject students were asked to program a simulation of adaptation based on the natural selection model in NetLogo. Both qualitative and quantitative data were collected in this study. The data resources included (1) pre and post test questionnaire, (2) student in-class worksheet, (3) programming planning sheet, (4) code-conception matching sheet, (5) student NetLogo projects, (6) videotaped programming processes, (7) final interview, and (8) investigator's field notes. Both qualitative and quantitative approaches were applied to analyze the gathered data. The findings suggested that students made progress on understanding adaptation phenomena and natural selection at the end of ABPM-supported MBI learning but the progress was limited. These students still held some misconceptions in their conceptual models, such as the idea that animals need to "learn" to adapt into the environment. Besides, their models of natural selection appeared to be

    In this paper, we propose a mathematical model in stochastic dynamic optimization form to determine the optimal strategy for an integrated single product inventory control problem and supplier selection problem where the demand and purchasing cost parameters are random. For each time period, by using the proposed model, we decide the optimal supplier and calculate the optimal product volume purchased from the optimal supplier so that the inventory level will be located at some point as close as possible to the reference point with minimal cost. We use stochastic dynamic programming to solve this problem and give several numerical experiments to evaluate the model. From the results, for each time period, the proposed model was generated the optimal supplier and the inventory level was tracked the reference point well. (paper)

    This paper presents a virtual reality system (the BlindAid) developed for orientation and mobility training of people who are newly blind. The BlindAid allows users to interact with different virtual structures and objects via auditory and haptic feedback. This case study aims to examine if and how the BlindAid, in conjunction with a traditional rehabilitation programme, can help people who are newly blind develop new orientation and mobility methods. Follow-up research based on this study, with a large experiment and control group, could contribute to the area of orientation and mobility rehabilitation training for the newly blind. The case study research focused on A., a woman who is newly blind, for 17 virtual sessions spanning ten weeks, during the 12 weeks of her traditional orientation and mobility rehabilitation programme. The research was implemented by using virtual environment (VE) exploration and orientation tasks in VE and physical spaces. The research methodology used both qualitative and quantitative methods, including interviews, questionnaire, videotape recording, and user computer logs. The results of this study helped elucidate several issues concerning the contribution of the BlindAid system to the exploration strategies and learning processes experienced by the participant in her encounters with familiar and unfamiliar physical surroundings.

    On the shelf and upper slope off Peru the signal of coastal upwelling productivity and bottom-water oxygen is well preserved in alternately laminated and bioturbated diatomaceous Quaternary sediments. Global sea-level fluctuations are the ultimate cause for these cyclic facies changes. During late Miocene time, coastal upwelling was about 100 km west of the present centers, along the edge of an emergent structure that subsequently subsided to form the modern slope. The sediments are rich in organic carbon, and intense microbially mediated decomposition of organic matter is evident in sulfate reduction and methanogenesis. These processes are accompanied by the formation of diagenetic carbonates, mostly Ca-rich dolomites and Mg-calcites. The downhole isotopic signatures of these carbonate cements display distinct successions that reflect the vertical evolution of the pore fluid environment. From the association of methane gas hydrates, burial depth, and low-chloride interstitial fluids, we suggest an additional process that could contribute to the characteristic chloride depletion in pore fluids of active margins: release of interlayer water from clays without a mineral phase change. The shelf sediments also contain a subsurface brine that stretches for more than 500 km from north to south over the area drilled. The source of the brine remains uncertain, although the composition of the oxygen isotopes suggests dissolution of evaporites by seawater.

    Full Text Available At present, big data is very popular, because it has proved to be much successful in many fields such as social media, E-commerce transactions, etc. Big data describes the tools and technologies needed to capture, manage, store, distribute, and analyze petabyte or larger-sized datasets having different structures with high speed. Big data can be structured, unstructured, or semi structured. Hadoop is an open source framework that is used to process large amounts of data in an inexpensive and efficient way, and job scheduling is a key factor for achieving high performance in big data processing. This paper gives an overview of big data and highlights the problems and challenges in big data. It then highlights Hadoop Distributed File System (HDFS, Hadoop MapReduce, and various parameters that affect the performance of job scheduling algorithms in big data such as Job Tracker, Task Tracker, Name Node, Data Node, etc. The primary purpose of this paper is to present a comparative study of job scheduling algorithms along with their experimental results in Hadoop environment. In addition, this paper describes the advantages, disadvantages, features, and drawbacks of various Hadoop job schedulers such as FIFO, Fair, capacity, Deadline Constraints, Delay, LATE, Resource Aware, etc, and provides a comparative study among these schedulers.

    1992-01-01

    The present publication appears for the first time on a regular basis. It follows the experimental Compendium, which at the time of its publication in 1987, marked the first attempt to compile statistics based on the intensive conceptual work on environment statistics that had taken place in the framework of the Conference of European Statisticians in the early 1980s. The publication is divided into two parts. Part One is devoted to standard statistics, time series and indicators on several aspects of the environment. Part Two is a statistical monograph of a complex environmental issue. The time it deals with environmental impacts of agriculture. It seeks to be a comprehensive description of the linkages between the actual environmental effects and the physical, social and economic characteristics of agricultural production. Data on environmental time series and indicators shown in Part One of this Compendium were obtained from two sources. First, international databases were used. Climate data from NCDC, Ashville and CAC, Washington D.C.; ICPB data on European bird populations; IUCN data on wetlands; FAO and ICES data on fish catches; ECE databases on energy and transport; WHO/UNEP GEMS Air data on urban air quality; EMEP/CCC and EMEP/MSC-W data on background air quality; ECE/FAO data on forest resources and fires; ECE/ICP data on forest damage; ECE/FAO data on forest fires and UNEP/GEMS Water data on freshwater quality are the international data sets used either exclusively or as the major source for the compilation of the respective sections of the Compendium. In particular, experts from the USSR and the United Kingdom contributed special chapters on the radiation situation in the former USSR after the Chernobyl accident and on health effects of low dose radiation.

    This report presents the results from the analysis of the 34th set of environmental quality assessment samples (QAP 34) that were received on or before June 10, 1991. This Quality Assessment Program (QAP) is designed to test the quality of the environmental measurements being reported to the Department of Energy by its contractors. Since 1976, real or synthetic environmental samples that have been prepared and thoroughly analyzed at the Environmental Measurements Laboratory (EML) have been distributed at first quarterly and then semi-annually to these contractors. Their results, which are returned to EML within 90 days, are compiled with EML's results and are reported back to the participating contractors 30 days later. A summary of the reported results is available to the participants 3 days after the reporting deadline via a modem-telephone connection to the EML computer. The ''EML value'' listed in the tables to which the contractors' results are compared is the mean of replicate determination for each nuclide. The EML uncertainty is the standard error of the mean. All other uncertainties are as reported by the participants

    Collaboration is a complex phenomenon, where intersubjective dynamics can greatly affect the productive outcome. Evaluation of collaboration is thus of great interest, and can potentially help achieve better outcomes and performance. However, quantitative measurement of collaboration is difficult, because much of the interaction occurs in the intersubjective space between collaborators. Manual observation and/or self-reports are subjective, laborious, and have a poor temporal resolution. The problem is compounded in natural settings where task-activity and response-compliance cannot be controlled. Physiological signals provide an objective mean to quantify intersubjective rapport (as synchrony), but require novel methods to support broad deployment outside the lab. We studied 28 student dyads during a self-directed classroom pair-programming exercise. Sympathetic and parasympathetic nervous system activation was measured during task performance using electrodermal activity and electrocardiography. Results suggest that (a) we can isolate cognitive processes (mental workload) from confounding environmental effects, and (b) electrodermal signals show role-specific but correlated affective response profiles. We demonstrate the potential for social physiological compliance to quantify pair-work in natural settings, with no experimental manipulation of participants required. Our objective approach has a high temporal resolution, is scalable, non-intrusive, and robust.

    Background: Modern contraceptive prevalence was 14.1% in 2007 in Kinshasa, the capital city of the Democratic Republic of the Congo (DRC). Yet virtually nothing was known about the family planning supply environment. Methods: Three surveys of health facilities were conducted in 2012, 2013, and 2014 to determine the number, spatial distribution, and attributes of sites providing family planning services. The 2012 and 2013 surveys aimed to identify the universe of family planning facilities while obtaining a limited set of data on “readiness” to provide family planning services (defined as having at least 3 modern methods, at least 1 person training in family planning in the last 3 years, and an information system to track distribution of products to clients) and output (measured by couple-years of protection, or CYP). In contrast, the 2014 survey, conducted under the umbrella of the Performance Monitoring and Accountability 2020 (PMA2020) project, was based on 2-stage cluster sampling. This article provides detailed analysis of the 2012 and 2013 surveys, including bivariate and multivariate analysis of correlates of readiness to provide services and of output. Results: We identified 184 health facilities that reported providing at least 1 contraceptive method in 2012 and 395 facilities in 2013. The percentage of sites defined as “ready” to provide services increased from 44.1% in 2012 to 63.3% in 2013. For the 3-month period between January and March 2013, facilities distributed between 0 and 879.2 CYP (mean, 39.7). Nearly half (49%) of the CYP was attributable to implants, followed by IUDs (24%), CycleBeads (11%), and injectables (8%). In 2013, facilities supported by PEPFAR (n = 121) were more likely than other facilities to be rated as ready to provide services (Pplanning implementing agencies (Pplanning in the DRC in many ways, including mobilizing partners to increase contraceptive access and increasing donor investment in family planning in the DRC

    ORL-students and residents have an ongoing debate about the "best" programme in Europe. Aim of this study was to comparatively assess differences among programmes in training, satisfaction, quality of life (QoL) of residents and recent otorhinolaryngologist (ORL) specialists in France, Germany, Spain, Italy, Austria, and Belgium. A self-administered anonymous questionnaire, structured in ten sections including general information, provided guidance, working environment, training structure, teaching of medical students, publication work, QoL, and satisfaction with training, were emailed to residents and recent ORL specialists. 476 returned questionnaires from 6 countries revealed that daily work hours were the highest in France and Belgium with 11 and 10.4 h on average, respectively. QoL, work conditions, and salary were best in Germany followed by Austria in terms of possibility of part-time contracts, better respect for post-duty day off, and compensation for overtime. Satisfaction with training including support and guidance of seniors was lowest in Italy, but, on the other hand, the publication work and support had a more important place than in other countries. In Belgium, there was some gap between the quality of teaching and feedback from seniors as well as apprenticeship. The highest satisfaction with training was in France and Spain followed by Austria. The study results provide guidance before choosing an ORL training programme in Europe. Country-specific strengths could be included into future harmonization efforts to improve all programmes, facilitate professional exchange and, finally, establish standards-of-care carried out by well-trained doctors also looking after a satisfying work-life balance.

  4. Energy, pollution, environment and health

    International Nuclear Information System (INIS)

    1999-01-01

    Many of the major environmental problems of today, such as climate change, air pollution, acidification of lakes and forests, deforestation and desertification, share a common causal factor: energy - its production, transformation and final use. The burning of fossil fuels has already contributed to acidification of lakes and forests, and threatens to alter the world's climate. Traditional open fires cause indoor air pollution, thereby harming the health of women and children in the Third World. In many developing countries, the disappearing forest base is increasingly unable to supply enough wood for energy needs, leading to even greater pressure on forests, which in turn can lead to desertification. Nuclear reactor accidents may release large quantities of radioactive materials, and hydro dams may fail and inundate large areas of land. Indeed, every energy system has some impact on health and the environment, either affecting the same group of people who enjoy the benefits: the exposure of a small group to fumes from a poorly vented common cooking device; or a different group: acid rain in one country caused by the burning of fossil fuels in another, or harm to the health of future generations from today's radioactive nuclear waste. During the past two decades, these energy- environment impacts have become so serious that they may limit further growth of the world's energy economy. Consequently, these problems are now being examined more closely by decision makers throughout the world, as well as by the general public. In addition, it has become clear that energy cannot be viewed in isolation and that pollution, environment and health issues must be integrated into the development of national and international energy policies, so that the adverse impacts of energy can be reduced. To do this, the relationships among different energy systems and their impacts need to be defined clearly. To that end, UNEP has convened conferences on this topic and prepared several

    An autopilot scheme of volumetric-modulated arc therapy (VMAT)/intensity-modulated radiation therapy (IMRT) planning with the guidance of prior knowl-edge is established with recorded interactions between a planner and a commercial treatment planning system (TPS). Microsoft (MS) Visual Studio Coded UI is applied to record some common planner-TPS interactions as subroutines. The TPS used in this study is a Windows-based Eclipse system. The interactions of our application program with Eclipse TPS are realized through a series of subrou-tines obtained by prerecording the mouse clicks or keyboard strokes of a planner in operating the TPS. A strategy to autopilot Eclipse VMAT/IMRT plan selection process is developed as a specific example of the proposed "scripting" method. The autopiloted planning is navigated by a decision function constructed with a reference plan that has the same prescription and similar anatomy with the case at hand. The calculation proceeds by alternating between the Eclipse optimization and the outer-loop optimization independent of the Eclipse. In the C# program, the dosimetric characteristics of a reference treatment plan are used to assess and modify the Eclipse planning parameters and to guide the search for a clinically sensible treatment plan. The approach is applied to plan a head and neck (HN) VMAT case and a prostate IMRT case. Our study demonstrated the feasibility of application programming method in C# environment with recorded interactions of planner-TPS. The process mimics a planner's planning process and automatically provides clinically sensible treatment plans that would otherwise require a large amount of manual trial and error of a planner. The proposed technique enables us to harness a commercial TPS by application programming via the use of recorded human computer interactions and provides an effective tool to greatly facilitate the treatment planning process. © 2016 The Authors.

    Vixen is a collection of enabling technologies for uninhibited distributed object computing. In the Spring of 1995 when Vixen was proposed, it was an innovative idea very much ahead of its time. But today the technologies proposed in Vixen have become standard technologies for Enterprise Computing. Sun Microsystems J2EE/EJB specifications, among others, are independently proposed technologies of the Vixen type. I have brought Vixen completely under the J2EE standard in order to maximize interoperability and compatibility with other computing industry efforts. Vixen and the Enterprise JavaBean (EJB) Server technologies are now practically identical; OIL, another Vixen technology, and the Java Messaging System (JMS) are practically identical; and so on. There is no longer anything novel or patentable in the Vixen work performed under this grant. The above discussion, notwithstanding, my independent development of Vixen has significantly helped me, my university, my students and the local community. The undergraduate students who worked with me in developing Vixen have enhanced their expertise in what has become the cutting edge technology of their industry and are therefore well positioned for lucrative employment opportunities in the industry. My academic department has gained a new course: "Multi-media System Development", which provides a highly desirable expertise to our students for employment in any enterprise today. The many Outreach Programs that I conducted during this grant period have exposed local Middle School students to the contributions that NASA is making in our society as well as awakened desires in many such students for careers in Science and Technology. I have applied Vixen to the development of two software packages: (a) JAS: Joshua Application Server - which allows a user to configure an EJB Server to serve a J2EE compliant application over the world wide web; (b) PCM: Professor Course Manager: a J2EE compliant application for configuring a

    This paper intends to describe the outline of the Eco Care Program (ECP) at the Siemens-Division Industry Solutions and its implementation. ECP aims to embrace and to coordinate main activities within the product lifecycle management (PLM) process considering both economic targets in terms of overall lifecycle costs as well as energy efficiency and other important environmental issues in the innovation management for industrial solutions. ECP consists of adapted methods for assessing the environmental and financial impacts of industrial solutions (plants, processes, single technologies or even services) and tools which helps to derive reliable assessment results. Life Cycle Assessment (LCA) is a suitable method for assessing environmental impacts of products and solutions over their entire lifecycle focusing on those lifecycle phases which may contribute significantly to environmental burdens or benefits. To meet these requirements the main challenge is to simplify the assessment methodology as far as reliability and accuracy of results is preserved. To present results in both dimensions of economical performance and environmental impact the paper introduces the concept of the 'eco care matrix' (ECM). Environmental sound industrial solutions have advantages in both 'eco' dimensions (eco-nomical + eco-logical). The analytical approach presented is further on implemented in two complementary and independent industrial application fields: in order to exemplify usability of the approach in quite complex process technology different hot metal producing technologies (blast furnace route vs. smelting reduction routes COREX / FINEX). The second pilot application is targeted on the assessment of infrastructure solutions especially focusing on the comparison of environmental and financial effects of different technologies and payment schemes of electronic city tolling systems for London and Copenhagen.

    The Herschel Space Observatory has enabled us to probe the physical conditions of outer disks, envelopes, and outflows of young stellar objects, including embedded objects, Herbig Ae/Be disks, and T Tauri disks. We will report on results from three projects, DIGIT, WISH, and FOOSH. The DIGIT (Dust, Ice, and Gas in Time) program (PI: Neal Evans) utilizes the full spectral range of the PACS instrument to explore simultaneously the solid and gas-phase chemistry around sources in all of these stages. WISH (Water in Star Forming Regions with Herschel, PI Ewine van Dishoeck) focuses on observations of key lines with HIFI and line scans of selected spectral regions with PACS. FOOSH (FU Orionis Objects Surveyed with Herschel, PI Joel Green) studies FU Orionis objects with full range PACS and SPIRE scans. DIGIT includes examples of low luminosity protostars, while FOOSH studies the high luminosity objects during outburst states. Rotational ladders of highly excited CO and OH emission are detected in both disks and protostars. The highly excited lines are more commonly seen in the embedded phases, where there appear to be two temperature components. Intriguingly, water is frequently detected in spectra of embedded sources, but not in the disk spectra. In addition to gas features, we explore the extent of the newly detected 69 um forsterite dust feature in both T Tauri and Herbig Ae/Be stars. When analyzed along with the Spitzer-detected dust features, these provide constraints on a population of colder crystalline material. We will present some models of individual sources, as well as some broad statistics of the emission from these stages of star and planet formation.

    More than 2 years after the Gulf conflict, scientists are continuing to keep a close watch on marine pollution stemming from the war. Following the conflict in early 1991, major concern was raised worldwide when an estimated four to eight million barrels of crude oil were directly released into the Persian Gulf from the Sea Island terminal in Kuwait. Such amounts clearly made it the largest oil spill in history. The catastrophe was exacerbated when Kuwaiti oil fields were ignited. The magnitude of the pollution, and the types of toxic contaminants involved, led to a worldwide response through the United Nations system. An inter-agency plan of action was developed quickly. As one of its steps, the co-ordinating agency - the United Nations Environment Programme (UNEP) - asked the IAEA's Marine Environment Laboratory (MEL) in Monaco to help make a preliminary assessment of the situation. The Laboratory's main goal in initial surveys was to map the extent and general degree of the war-related pollution throughout the Gulf. Since the initial surveys were done, IAEA-MEL scientists have been engaged in regional follow-up activities in ongoing attempts to obtain a clearer picture of the oil pollution's effects on the Gulf's marine environment. This article highlights the laboratory's work in the Gulf following the 1991 conflict, within the context of co-operative programmes and projects. 1 fig

    The computer programs ARRRG and FOOD were written to facilitate the calculation of internal radiation doses to man from the radionuclides in the environment and external radiation doses from radionuclides in the environment. Using ARRRG, radiation doses to man may be calculated for radionuclides released to bodies of water from which people might obtain fish, other aquatic foods, or drinking water, and in which they might fish, swim or boat. With the FOOD program, radiation doses to man may be calculated from deposition on farm or garden soil and crops during either an atmospheric or water release of radionuclides. Deposition may be either directly from the air or from irrigation water. Fifteen crop or animal product pathways may be chosen. ARRAG and FOOD doses may be calculated for either a maximum-exposed individual or for a population group. Doses calculated are a one-year dose and a committed dose from one year of exposure. The exposure is usually considered as chronic; however, equations are included to calculate dose and dose commitment from acute (one-time) exposure. The equations for calculating internal dose and dose commitment are derived from those given by the International Commission on Radiological Protection (ICRP) for body burdens and Maximum Permissible Concentration (MPC) of each radionuclide. The radiation doses from external exposure to contaminated farm fields or shorelines are calculated assuming an infinite flat plane source of radionuclides. A factor of two is included for surface roughness. A modifying factor to compensate for finite extent is included in the shoreline calculations

  12. A Dynamic Programming-Based Sustainable Inventory-Allocation Planning Problem with Carbon Emissions and Defective Item Disposal under a Fuzzy Random Environment

    2018-01-01

    Full Text Available There is a growing concern that business enterprises focus primarily on their economic activities and ignore the impact of these activities on the environment and the society. This paper investigates a novel sustainable inventory-allocation planning model with carbon emissions and defective item disposal over multiple periods under a fuzzy random environment. In this paper, a carbon credit price and a carbon cap are proposed to demonstrate the effect of carbon emissions’ costs on the inventory-allocation network costs. The percentage of poor quality products from manufacturers that need to be rejected is assumed to be fuzzy random. Because of the complexity of the model, dynamic programming-based particle swarm optimization with multiple social learning structures, a DP-based GLNPSO, and a fuzzy random simulation are proposed to solve the model. A case is then given to demonstrate the efficiency and effectiveness of the proposed model and the DP-based GLNPSO algorithm. The results found that total costs across the inventory-allocation network varied with changes in the carbon cap and that carbon emissions’ reductions could be utilized to gain greater profits.

    Participation in the Supplemental Nutrition Assistance Program (SNAP) has been linked to an increased risk of obesity, but not much is known about the mechanisms behind this association. The objective of this study was to determine if the neighborhood density of unhealthy food outlets modifies the association between obesity and participation in SNAP. Data comes from the first wave of the Los Angeles Family and Neighborhood Survey; included are a subsample of adults (18+ years) who were SNAP participants or eligible non-participants (N = 1,176). We carried out multilevel analyses with obesity (BMI ≥ 30 Kg/m 2 ), SNAP participation, and the neighborhood density of unhealthy food outlets as dependent, independent and modifying variables, respectively, controlling for age, gender, race/ethnicity, marital status, working status, mental health, and neighborhood poverty. SNAP participants had double the odds of obesity compared to eligible non-participants (OR = 2.02; 95%CI = 1.44-2.83). However, the neighborhood density of unhealthy food outlets did not modify this association. SNAP participation was associated with higher odds of obesity in our primarily Hispanic sample in Los Angeles County, with no effect modification found for the unhealthy portion of the food environment. More research is needed with additional food environment measures to confirm our null findings. Additional research is needed to elucidate the mechanisms linking SNAP participation and obesity as they remain unclear.

  14. The supplemental instruction program: Student perceptions of the learning environment and impact on student academic achievement in college science at California State University, San Marcos

    Hizer, Suzanne Elizabeth

    Higher education in science has been criticized and calls to increase student learning and persistence to degree has been recognized as a national problem by the Department of Education, the National Science Foundation, the National Research Council, and the National Academy of Sciences. One mode of academic assistance that may directly address this issue is the implementation of Supplemental Instruction (SI) in science courses. SI is a specific model of academic assistance designed to help students in historically difficult science classes master course content, thus increasing their academic achievement and retention. This study assessed the SI program at California State University, San Marcos, in supported science courses. Specifically, academic achievement based on final course grades were compared between SI participating and nonparticipating students, multiple affective factors were measured at the beginning and end of the semester, and students' perceptions of the classroom and SI session learning environments recorded. Overall, students who attended five or more SI sessions achieved higher final course grades. Students who chose to participate in SI had higher initial levels of responsibility and anxiety. Additionally, SI participants experienced a reduction in anxiety over the semester whereas nonparticipants experienced an increase in anxiety from beginning to the end of the semester. The learning environment of SI embodies higher levels of constructivist principles of active learning such as cooperation, cohesiveness, innovation, and personalization---with one exception for the physics course, which is a based on problem-based learning. Structural equation modeling of variables indicates that high self-efficacy at the end of the semester is directly related to high final course grades; this is mediated by cohesion in the classroom and the cooperation evidenced in SI sessions. These findings are elaborated by student descriptions of what happened in SI

    Obesity is a public health problem that disproportionately affects low-income populations. Moreover, participation in Supplemental Nutrition Assistance Program (SNAP) has been associated with obesity among low-income women. The goal of this study was to determine the impact of intrapersonal, home environment, community and social factors on diet quality and body mass index (BMI) of low-income women participating in SNAP. This study also aimed to examine the role of these factors in mediating the relationship between food insecurity and diet quality, and BMI. A total of 152 women receiving SNAP benefits were recruited from low-income neighborhood centers and housing communities, and administered a demographics questionnaire, the United States adult food security scale, food frequency questionnaire, and multi-dimensional home environment scale (MHES). They also were measured for height and weight to calculate BMI. The Dietary Guidelines Adherence Index 2015 was used to measure diet quality. Regression analyses were conducted to determine the MHES subscales that were significant predictors of diet quality and BMI. The Preacher and Hayes mediation model was used to evaluate the mediation of the relationship between food insecurity and diet quality, and BMI by the MHES. Emotional eating resistance and favorable social eating behaviors were positively associated with diet quality; whereas emotional eating resistance, lower availability of unhealthy food at home, neighborhood safety and favorable social eating behaviors were inversely associated with BMI in women participating in SNAP. The MHES significantly mediated the relationship between food insecurity and BMI. These results emphasize the importance of intrapersonal, home environment, community and social factors in mediating the relationship between food insecurity and BMI in low-income women.

    In 1999 the Balkan's conflict lead NATO war planes to leave 10x10 3 kg of depleted uranium (DU) in the environment of Kosovo and neighbouring states (UNEP, 2001). DU behaves in the same manner in the environment as natural uranium and it can be traced with isotopic analysis due to the fact that DU has the isotopic composition of 0.2% 235 U and 99.8% 2 38 U as opposed to natural uranium which has 0.7% 2 35 U and 99.3% 2 38 U. DU is a waste product of the nuclear industry which enrich nuclear fuel by 2 35 U. Large stock piles of DU therefore exist in countries that produce nuclear energy and/or nuclear weapons. The DU is given to the weapons industry for free (or cheap) and has been a popular choice for armour penetrating arsenal due to the high density of uranium (19 g cm -3 ) and therefore its high penetrating power. Indeed the arsenal used in Kosovo consisted of DU penetrators that were shot from A-10 aeroplanes. They weigh roughly 300 g and have the shape of a fat 9 cm long pencil. (author)

  18. Designing and Using Virtual Field Environments to Enhance and Extend Field Experience in Professional Development Programs in Geology for K-12 Teachers

    2011-12-01

    Virtual reality (VR) is increasingly used to acquaint geoscience novices with some of the observation, data gathering, and problem solving done in actual field situations by geoscientists. VR environments in a variety of forms are used to prepare students for doing geologic fieldwork, as well as to provide proxies for such experience when venturing into the field is not possible. However, despite increased use of VR for these purposes, there is little research on how students learn using these environments, how using them impacts student field experience, or what constitutes effective design in light of emerging theories of geocognition. To address these questions, I investigated the design and use of a virtual reality environment in a professional development program for middle school Earth science teachers called Teachers on the Leading Edge (TOTLE). This environment, called a virtual field environment, or VFE, was based largely on the field sites visited by the participants during summer workshops. It was designed as a tool to prepare the participants for workshop field activities and as a vehicle for taking elements of that experience back to their students. I assessed how effectively the VFE accomplished these goals using a quasi-experimental, mixed method study that involved a series of teaching experiments, interviews, participant surveys, and focus groups. The principle conclusions reached in this study are as follows: 1. In a field trip orientation experiment involving 35 middle school teachers, 90.6% of the participants stated a preference for VFE enhanced orientation over an alternative orientation that used photographs and static maps to complete a practice field activity. When asked about how the VFE prepared them for their field experience, the participants ranked it as most helpful for visualize the location and geography of the field sites. They ranked it lower for helping them visualize structural and geomorphic patterns, and ranked it as least

    The perinatal period is a window of heightened plasticity that lays the groundwork for future anatomic, physiologic, and behavioral outcomes. During this time, maternal diet plays a pivotal role in the maturation of vital organs and the establishment of neuronal connections. However, when perinatal nutrition is either lacking in specific micro- and macronutrients or overloaded with excess calories, the consequences can be devastating and long lasting. The brain is particularly sensitive to perinatal insults, with several neurologic and psychiatric disorders having been linked to a poor in utero environment. Diseases characterized by learning and memory impairments, such as autism, schizophrenia, and Alzheimer disease, are hypothesized to be attributed in part to environmental factors, and evidence suggests that the etiology of these conditions may date back to very early life. In this review, we discuss the role of the early-life diet in shaping cognitive outcomes in offspring. We explore the endocrine and immune mechanisms responsible for these phenotypes and discuss how these systemic factors converge to change the brain's epigenetic landscape and regulate learning and memory across the lifespan. Through understanding the maternal programming of cognition, critical steps may be taken toward preventing and treating diseases that compromise learning and memory. © 2017 American Society for Nutrition.

    Hybrid silicon photon-counting detectors are becoming standard equipment for many synchrotron applications. The latest in the Medipix family of read-out chips designed as part of the Medipix Collaboration at CERN is the Medipix3, which while maintaining the same pixel size as its predecessor, offers increased functionality and operating modes. The active area of the Medipix3 chip is approx 14mm × 14mm (containing 256 × 256 pixels) which is not large enough for many detector applications, this results in the need to tile many sensors and chips. As a first step on the road to develop such a detector, it was decided to build a prototype single chip readout system to gain the necessary experience in operating a Medipix3 chip. To provide a flexible learning and development tool it was decided to build an interface based on the recently released FlexRIOTM system from National Instruments and to use the LabVIEWTM graphical programming environment. This system and the achieved performance are described in this paper.

    This cross-sectional study examined the: (1) association between food store environment (FSE), fruit and vegetable (FV) availability and access, and prevalence of early childhood overweight/obesity (COWOB); and (2) influence of young child actual FV intake on the relationship between the FSE and early COWOB prevalence. Anthropometric and socio-demographic data of children (2 to 8 years; N=466) in baseline communities on Guam participating in the Children's Healthy Living (CHL) Program community trial were included. CDC year 2000 growth charts were used to calculate BMI z-scores and categories. FSE factors (fresh FV scores, store type) were assessed using the CX3 Food Availability and Marketing Survey amended for CHL. ArcGIS maps were constructed with geographic coordinates of participant residences and food stores to calculate food store scores within 1 mile of participant's residences. A sub-sample of participants (n = 355) had Food and Activity Log data to calculate FV and energy intakes. Bivariate correlations and logistic regression evaluated associations. Of 111 stores surveyed, 73% were small markets, 16% were convenience stores, and 11% were large grocery/supermarkets. Supermarkets/large grocery stores averaged the highest FV scores. Most participants did not meet FV intake recommendations while nearly half exceeded energy intake recommendations. Living near a small market was negatively correlated with BMI z-score (r = - 0.129, P associations. The high density of small markets may be an opportunity for FSE intervention but further investigation of Guam's FSE influence on health is needed.

    The Framework for Interdisciplinary Design Optimization (FIDO) is a general programming environment for automating the distribution of complex computing tasks over a networked system of heterogeneous computers. For example, instead of manually passing a complex design problem between its diverse specialty disciplines, the FIDO system provides for automatic interactions between the discipline tasks and facilitates their communications. The FIDO system networks all the computers involved into a distributed heterogeneous computing system, so they have access to centralized data and can work on their parts of the total computation simultaneously in parallel whenever possible. Thus, each computational task can be done by the most appropriate computer. Results can be viewed as they are produced and variables changed manually for steering the process. The software is modular in order to ease migration to new problems: different codes can be substituted for each of the current code modules with little or no effect on the others. The potential for commercial use of FIDO rests in the capability it provides for automatically coordinating diverse computations on a networked system of workstations and computers. For example, FIDO could provide the coordination required for the design of vehicles or electronics or for modeling complex systems.

    Alberta Environment's water management operations (WMO) own and operates 46 dams and 800 km of canals. This presentation discussed a rehabilitation program designed to improve the safety of the WMO's Calgary weir which was built in 1908 to encourage settlement in the province. The weir includes a 32 m wide sluiceway, a 2.5 m concrete weir, and a fish ladder. A portage trail has been built to accommodate canoes, and signs are posted to indicate the hazards associated with the weir. The WMO has also launched an advertising campaign to outline hazards to the general public. The WMO has a contract with the Calgary fire department (CFD) to maintain a safety boom and provide rescue operations at the weir. The weir project aims to accommodate access and safety while enhancing flood conveyance capabilities of the weir. The project will allow upstream passage for patrol boats operated by the Calgary fire department's aquatic rescue service. The final design of the weir will include a series of drops constructed downstream of the weir to create pool and riffle structures that will eliminate hydraulic rollers. Notches will be cut in the weir to regulate flows moving through the new low and high flow channels. Case studies of other low-head dams operated by the WMO were also presented. tabs., figs.

    To evaluate the effectiveness of a leadership and management program in aged care. Double-blind cluster randomized controlled trial. Twelve residential and community-aged care sites in Australia. All care staff employed for 6 months or longer at the aged care sites were invited to participate in the surveys at 3 time points: baseline (time 1), 9 months from baseline (time 2), and 9 months after completion of time 2 (time 3) from 2011 to 2013. At each time point, at least 500 care staff completed a survey. At baseline (N = 503) the largest age group was 45 to 54 years (37%), and the majority of care staff were born in Australia (70%), spoke English (94%), and had at least completed secondary education (57%). A 12-month Clinical Leadership in Aged Care (CLiAC) program for middle managers, which aimed to further develop their leadership and management skills in creating positive workplace relationships and in enabling person-centered, evidence-based care. The primary outcomes were care staff ratings of the work environment, care quality and safety, and staff turnover rates. Secondary outcomes were care staff's intention to leave their employer and profession, workplace stress, job satisfaction, and cost-effectiveness of implementing the program. Absenteeism was excluded due to difficulty in obtaining reliable data. Managers' self-rated knowledge and skills in leadership and management are not included in this article, which focuses on care staff perceptions only. At 6 months after its completion, the CLiAC program was effective in improving care staff's perception of management support [mean difference 0.61, 95% confidence interval (CI) 0.04-1.18; P = .04].

    1998-03-01

    The purpose of this paper is to provide a summary analysis and comparison of various environment, safety, and health (ES&H) management systems required of, or suggested for use by, the Departrnent of Energy Defense Programs` sites. The summary analysis is provided by means of a comparison matrix, a set of Vean diagrams that highlights the focus of the systems, and an `End Gate` filter diagram that integrates the three Vean diagrams. It is intended that this paper will act as a starting point for implementing a particular system or in establishing a comprehensive site-wide integrated ES&H management system. Obviously, the source documents for each system would need to be reviewed to assure proper implementation of a particular system. The matrix compares nine ES&H management systems against a list of elements generated by identifying the unique elements of all the systems. To simplify the matrix, the elements are listed by means of a brief title. An explanation of the matrix elements is provided in Attachment 2 entitled, `Description of System Elements.` The elements are categorized under the Total Quality Management (TQM) `Plan, Do, Check, Act` framework with the added category of `Policy`. (The TQM concept is explained in the `DOE Quality Management implementation Guidelines,` July 1997 (DOE/QM- 0008)). The matrix provides a series of columns and rows to compare the unique elements found in each of the management systems. A `V` is marked if the element is explicitly identified as part of the particular ES&H management system. An `X` is marked if the element is not found in the particular ES&H management system, or if it is considered to be inadequately addressed. A `?` is marked if incorporation of the element is not clear. Attachment I provides additional background information which explains the justification for the marks in the matrix cells. Through the Vean diagrams and the `End Gate` filter in Section 3, the paper attempts to pictorially display the focus of

    1999-01-01

    A large number of assessments of regional marine areas have been conducted in recent years for a variety of purposes. Periodic reviews of the state of the marine environment have been undertaken by the United Nations Joint Group of Experts on the Scientific Aspects of Marine Environmental Protection (GESAMP). The most recent of these global assessments was published in 1990. The international adoption of a Global Programme of Action for the Protection of the Marine Environment from Land-Based Activities in 1995 has led to additional demand for regional assessments and a global review. The regional assessments are either completed or in train largely through mechanisms associated with the UNEP Regional Seas Programme. The global assessment has been assigned to GESAMP and incorporated into its plans for the preparation of a new global review to be completed in the year 2002. The Intergovernmental Oceanographic Commission, (IOC) the Scientific Committee for Oceanic Research (SCOR) and the Scientific Committee on Problems of the Environment (SCOPE) are collaborating in a review of ocean science. The Global Environment Facility (GEF) recently approved funding for a 'Global International Waters Assessment' (GIWA) partly as a means of determining priorities within its International Waters Portfolio. This paper outlines the nature of, and contemporary activities within, these various assessments. (author)

    The intrauterine environment has a strong influence on pregnancy outcome. The placenta and the umbilical cord together form the main supply line of the fetus. Amniotic fluid also serves important functions. These three main components decide whether there will be an uneventful pregnancy and the successful birth of a healthy baby. An insult to the intrauterine environment has an impact on the programming of the fetus, which can become evident in later life, mainly in the form of cardiovascular diseases, diabetes, and certain learning disabilities. The past two decades have witnessed major contributions from researchers in this field, who have included ultrasonologists, epidemiologists, neonatologists, and pediatricians. Besides being responsible for these delayed postnatal effects, abnormalities of the placenta, umbilical cord, and amniotic fluid also have associations with structural and chromosomal disorders. Population and race also influence pregnancy outcomes to some extent in certain situations. USG is the most sensitive imaging tool currently available for evaluation of these factors and can offer considerable information in this area. This article aims at reviewing the USG-related developments in this area and the anatomy, physiology, and various pathologies of the placenta, umbilical cord, and the amniotic fluid

  15. Development of a modular streamflow model to quantify runoff contributions from different land uses in tropical urban environments using Genetic Programming

    2015-06-01

    The decrease of pervious areas during urbanization has severely altered the hydrological cycle, diminishing infiltration and therefore sub-surface flows during rainfall events, and further increasing peak discharges in urban drainage infrastructure. Designing appropriate waster sensitive infrastructure that reduces peak discharges requires a better understanding of land use specific contributions towards surface and sub-surface processes. However, to date, such understanding in tropical urban environments is still limited. On the other hand, the rainfall-runoff process in tropical urban systems experiences a high degree of non-linearity and heterogeneity. Therefore, this study used Genetic Programming to establish a physically interpretable modular model consisting of two sub-models: (i) a baseflow module and (ii) a quick flow module to simulate the two hydrograph flow components. The relationship between the input variables in the model (i.e. meteorological data and catchment initial conditions) and its overall structure can be explained in terms of catchment hydrological processes. Therefore, the model is a partial greying of what is often a black-box approach in catchment modelling. The model was further generalized to the sub-catchments of the main catchment, extending the potential for more widespread applications. Subsequently, this study used the modular model to predict both flow components of events as well as time series, and applied optimization techniques to estimate the contributions of various land uses (i.e. impervious, steep grassland, grassland on mild slope, mixed grasses and trees and relatively natural vegetation) towards baseflow and quickflow in tropical urban systems. The sub-catchment containing the highest portion of impervious surfaces (40% of the area) contributed the least towards the baseflow (6.3%) while the sub-catchment covered with 87% of relatively natural vegetation contributed the most (34.9%). The results from the quickflow

    Although an array of federal, state, and local programs exist that target food insecurity and the specific nutritional needs of seniors, food insecurity among older adults in the United States remains a persistent problem, particularly in minority and rural populations. Food insecurity is highly predictive of inadequate fresh fruit and vegetable (FFV) consumption in particular. The Senior Farmers' Market Nutrition Program (SFMNP) is a community-based program to help seniors purchase FFVs at farmer's markets in their neighborhoods. The SFMNP continues to grow; however, little is known about the effectiveness of the program. The purposes of this article are to (1) highlight the importance of community and neighborhood based food insecurity programs, specifically emphasizing the importance of FFV access for seniors, (2) review the current state of the evidence on the SFMNP, and (3) provide recommendations for researchers and policy-makers wishing to continue to advance the knowledge base in neighborhood-based food security among older adults.

    Full Text Available Abstract Background Sustained employability and health are generating awareness of employers in an aging and more complex work force. To meet these needs, employers may offer their employees health surveillance programs, to increase opportunities to work on health and sustained employability. However, evidence for these health surveillance programs is lacking. The FLESH study (Functional Labour Evaluation for Sustained Health and employment was developed to evaluate a comprehensive workers’ health promotion program on its effectiveness, cost-benefit, and process of the intervention. Methods The study is designed as a cluster randomised stepped wedge trial with randomisation at company plant level and is carried out in a large meat processing company. Every contracted employee is offered the opportunity to participate in the POSE program (Promotion Of Sustained Employability. The main goals of the POSE program are 1 providing employee’s insight into their current employability and health status, 2 offering opportunities to improve employability and decrease health risks and 3 improving employability and health sustainably in order to keep them healthy at work. The program consists of a broad assessment followed by a counselling session and, if needed, a tailored intervention. Measurements will be performed at baseline and will be followed up at 20, 40, 60, 80, 106 and 132 weeks. The primary outcome measures are work ability, productivity and absenteeism. Secondary outcomes include health status, vitality, and psychosocial workload. A cost-benefit study will be conducted from the employers’ perspective. A process evaluation will be conducted and the satisfaction of employer and employees with the program will be assessed.

    Fusion energy is not as mature as the other energy options. However, in recent years fusion research has focused on its energy mission, and the progress has been impressive. Ten years ago, many observers questioned whether fusion in the laboratory was scientifically feasible. Today, few question fusion's basic feasibility, and the issues have shifted to its economic and environmental aspects. This is a measure of the progress the program has made. For the reasons outlined here, the author requests Congress to support at a minimum the Administration's FY96 budget request of $366 Million for fusion energy. This level permits the program to continue developing the tokamak as its principal fusion concept. The level is, however, insufficient to pursue meaningful development of specialized materials and non-tokamak alternatives which are sure to play important roles in enabling fusion to reach its highest potential attractiveness

    Spreadsheet management is a border-land between office applications and programming, however, it is rather communicated that spreadsheet is nothing more than an easily handled fun piece. Consequently, the complexity of spreadsheet handling, the unprepared end-users, their problem solving abilities and approaches do not match. To overcome these problems we have developed and introduced Sprego (Spreadsheet Lego). Sprego is a simplified functional programming language in spreadsheet environment,...

  1. Programming the offspring through altered uteroplacental hemodynamics: how maternal environment impacts uterine and umbilical blood flow in cattle, sheep and pigs.

    As placental growth and vascularity precedes exponential fetal growth, not only is proper establishment of the placenta important, but also a continual plasticity of placental function throughout gestation. Inadequate maternal environment, such as nutritional plane, has been documented to alter fetal organogenesis and growth, thus leading to improper postnatal growth and performance in many livestock species. The timing and duration of maternal nutritional restriction appears to influence the capillary vascularity, angiogenic profile and vascular function of the placenta in cattle and sheep. In environments where fetal growth and/or fetal organogenesis are compromised, potential therapeutics may augment placental nutrient transport capacity and improve offspring performance. Supplementation of specific nutrients, including protein, as well as hormone supplements, such as indolamines, during times of nutrient restriction may assist placental function. Current use of Doppler ultrasonography has allowed for repeated measurements of uterine and umbilical blood flow including assessment of uteroplacental hemodynamics in cattle, sheep and swine. Moreover, these variables can be monitored in conjugation with placental capacity and fetal growth at specific time points of gestation. Elucidating the consequences of inadequate maternal intake on the continual plasticity of placental function will allow us to determine the proper timing and duration for intervention.

    Youth advocacy for obesity prevention is a promising but under-evaluated intervention. The aims of this study are to evaluate a youth advocacy program's outcomes related to youth perceptions and behaviors, develop an index of youth advocacy readiness, and assess potential predictors of advocacy readiness. Youth ages 9-22 in an advocacy training program (n = 92 matched pairs) completed surveys before and after training. Youth outcomes and potential predictors of advocacy readiness were assessed with evaluated scales. All 20 groups who completed the evaluation study presented their advocacy projects to a decision maker. Two of six perception subscales increased following participation in the advocacy program: self-efficacy for advocacy behaviors (p assertiveness (p < .01), health advocacy history (p < .001), knowledge of resources (p < .01), and social support for health behaviors (p < .001). Youth increased days of meeting physical activity recommendations (p < .05). In a mixed regression model, four subscales were associated with the advocacy readiness index: optimism for change (B = 1.46, 95 % CI = .49-2.44), sports and physical activity enjoyment (B = .55, 95 % CI = .05-1.05), roles and participation (B = 1.81, 95 % CI = .60-3.02), and advocacy activities (B = 1.49, 95 % CI = .64-2.32). The youth advocacy readiness index is a novel way to determine the effects of multiple correlates of advocacy readiness. Childhood obesity-related advocacy training appeared to improve youths' readiness for advocacy and physical activity.

    Many science and research skills are taught by osmosis in graduate programs with the expectation that students will develop good communication skills (speaking, writing, and networking) by observing others, attending meetings, and self reflection. A new National Science Foundation Graduate Teaching Fellows in K- 12 Education (GK-12; http://ehrweb.aaas.org/gk12new/) program at UCLA (SEE-LA; http://measure.igpp.ucla.edu/GK12-SEE-LA/overview.html ) attempts to make the development of good communication skills an explicit part of the graduate program of science and engineering students. SEE-LA places the graduate fellows in two pairs of middle and high schools within Los Angeles to act as scientists-in- residence. They are partnered with two master science teachers and spend two-days per week in the classroom. They are not student teachers, or teacher aides, but scientists who contribute their content expertise, excitement and experience with research, and new ideas for classroom activities and lessons that incorporate inquiry science. During the one-year fellowship, the graduate students also attend a year-long Preparing Future Faculty seminar that discusses many skills needed as they begin their academic or research careers. Students are also required to include a brief (two-page) summary of their research that their middle or high school students would be able to understand as part of their published thesis. Having students actively thinking about and communicating their science to a pre-college audience provides important science communication training and helps contribute to science education. University and local pre- college school partnerships provide an excellent opportunity to support the development of graduate student communication skills while also contributing significantly to the dissemination of sound science to K-12 teachers and students.

    The Metal Mining Effluent Regulations (MMER) took effect in 2002 and require most metal mining operations in Canada to complete environmental effects monitoring (EEM) programs. An "effect" under the MMER EEM program is considered any positive or negative statistically significant difference in fish population, fish usability, or benthic invertebrate community EEM-defined endpoints. Two consecutive studies with the same statistically significant differences trigger more intensive monitoring, including the characterization of extent and magnitude and investigation of cause. Standard EEM study designs do not require multiple reference areas or preexposure sampling, thus results and conclusions about mine effects are highly contingent on the selection of a near perfect reference area and are at risk of falsely labeling natural variation as mine related "effects." A case study was completed to characterize the natural variability in EEM-defined endpoints during preexposure or baseline conditions. This involved completing a typical EEM study in future reference and exposure lakes surrounding a proposed uranium (U) mine in northern Saskatchewan, Canada. Moon Lake was sampled as the future exposure area as it is currently proposed to receive effluent from the U mine. Two reference areas were used: Slush Lake for both the fish population and benthic invertebrate community surveys and Lake C as a second reference area for the benthic invertebrate community survey. Moon Lake, Slush Lake, and Lake C are located in the same drainage basin in close proximity to one another. All 3 lakes contained similar water quality, fish communities, aquatic habitat, and a sediment composition largely comprised of fine-textured particles. The fish population survey consisted of a nonlethal northern pike (Esox lucius) and a lethal yellow perch (Perca flavescens) survey. A comparison of the 5 benthic invertebrate community effect endpoints, 4 nonlethal northern pike population effect endpoints

    Experiments on Apollo missions 15, 16, and 17 were utilized in an attempt to learn about the induced environment in the vicinity of manned spacecraft. Photographic sequences were examined to obtain scattered light data from the spacecraft-generated particulates during quiescence periods and after liquid dumps. The results allowed estimates of the obscuration factor and the clearing times after dumps. It was found that the clearing times were substantially longer than anticipated. The mass spectrometer detected a high molecular flux in lunar orbit which was induced by the spacecraft. It is shown that this is most likely caused by small ice crystals being continually produced in lunar orbit. Other data from the ultraviolet spectrometer and the stellar camera are also analyzed, and estimated values or upper limits are placed on the total scattering background, the size and number of particles generated, the velocity range, and the column density.

    United States Astronauts have a very unique occupational exposure profile. In order to understand these risks and properly address them, the National Aeronautics and Atmospheric Administration, NASA, originally created the Longitudinal Study of Astronaut Health, LSAH. The first LSAH was designed to address a variety of needs regarding astronaut health and included a 3 to 1 terrestrial control population in order to compare United States "earth normal" disease and aging to that of a microgravity exposed astronaut. Over the years that program has been modified, now termed Lifetime Surveillance of Astronaut Health, still LSAH. Astronaut spaceflight exposures have also changed, with the move from short duration shuttle flights to long duration stays on international space station and considerable terrestrial training activities. This new LSAH incorporates more of an occupational health and medicine model to the study of occupationally exposed astronauts. The presentation outlines the baseline exposures and monitoring of the astronaut population to exposures, both terrestrial, and in space.

    Supplier selection (SS) is a multi-criteria and multi-objective problem, in which multi-segment (e.g. imperfect-quality discount (IQD) and price-quantity discount (PQD)) and multi-aspiration level problems may be significantly important; however, little attention had been given to dealing with both of them simultaneously in the past. This study proposes a model for integrating multi-choice goal programming and multi-segment goal programming to solve the above-mentioned problems by providing the following main contributions: (1) it allows decision-makers to set multiple aspiration levels on the right-hand side of each goal to suit real-world situations, (2) the PQD and IQD conditions are considered in the proposed model simultaneously and (3) the proposed model can solve a SS problem with n suppliers where each supplier offers m IQD with r PQD intervals, where only ? extra binary variables are required. The usefulness of the proposed model is explained using a real case. The results indicate that the proposed model not only can deal with a SS problem with multi-segment and multi-aspiration levels, but also can help the decision-maker to find the appropriate order quantities for each supplier by considering cost, quality and delivery.

    Introduction Noise-induced hearing loss (NIHL) is a serious problem for workers and therefore for businesses. The hearing conservation program (HCP) is a set of coordinated measures to prevent the development or evolution of occupational hearing loss, which involves a continuous and dynamic process of implementation of hearing conservation routines through anticipation, recognition, evaluation, and subsequent control of the occurrence of existing environmental risks or of those that may exist in the workplace and lead to workers' hearing damage. Objective The aim of this study was to evaluate the effectiveness of the HCP in preventing further hearing loss in workers with audiograms suggestive of NIHL. The audiometric tests and medical records of 28 furniture company workers exposed to noise were reviewed and monitored for 2 years. Methods This retrospective, cross-sectional study examined five audiometric tests in the medical records (on admission and every semester) of 28 workers in a furniture company (totaling 140 audiometric exams) following the introduction of the HCP. Results Data analysis showed no differences between the audiometric tests conducted on admission and those performed every semester. Conclusions The HCP implemented was effective in preventing the worsening of hearing loss in workers already with NIHL when exposed to occupational noise. Therefore, such a measure could be useful for the employment of workers with hearing loss in job sectors that have noise exposure.

    The application independent simulation system KISMET was developed. This tool gives a different approach compared to previously existing robot simulators. A hierarchical data structure approach is used for the definition of workcell geometry, assembly topology and mechanism kinematics. This database structure allows for presentation of interactively selectable levels of detail and is, therefore, especially useful for real-time rigid body simulation of complex RH-scenarios. With KISMET, assembly structures can be modelled in any number of detail levels. Workcell geometry, assembly topology and mechanisms can be defined interactively by means of the integrated modeller. The mechanism simulation allows for kinematical tree structures with any number of joints, planar closed chains, and interconnections between joints. Examples of novel simulation methods, data structures, and algorithms are presented for selected examples: the hidden surface problem, graphical presentation techniques, collision testing, and control of scene cameras (image simulation, fast positioning and tracking). Special attention is paid to the real-time problem. The way this system was realized within the UNIX world is shown as an example for geometric and kinematic modelling techniques that grant for the optimum use of the capabilities of high-performance graphics workstations. A further chapter is focussing on the use of standard interfaces for CAD model transfer (CAD * I, STEP) and robot programming (IRDATA). Examples of practical KISMET applications for remote handling in fusion reactors, in a nuclear fuel element reprocessing cell and in sensor based robotics are used to present the developed methods.

    As a contribution to Germany's "Science Year 2016*17 - Seas and Oceans", a large science outreach program organized and financed by the National Ministry for Education and Research, GeoUnion, the umbrella organization of Earth science associations and institutions in Germany, has conducted a series of advance level workshops for out-of-school educators and interpreters in Germany. The workshops were organized in co-operation with geoparks, biosphere reserve areas and other environmental management institutions all over Germany. The goal was to convey various perspectives of modern marine sciences to inland venues, linking important present-day marine themes with the presentation of marine phases in the geological history of the host region. The workshops were designed for park rangers, museum educationalists and other science communicators, initiating a broader impact on target groups such as school classes, (geo-)tourists and stakeholder groups. Our approach has been to combine lectures by top-level scientists (on both ocean literacy aspects and regional geology) with discussions and an on-the-spot learning-and-presenting module based on prepared text and visual material. Beyond earth science issues we have integrated economy, ecology, social sciences as well as arts and humanities aspects. One central topic was the role of the world ocean in climate change; other themes highlighted sea level rise, the thermohaline circulation, sea-floor spreading, coral reefs, over-fishing, various marine species and the problem of plastic waste in the ocean. We had anticipated that marine issues are actually very rarely discussed in inland Germany. A structured presentation of ocean literacy elements has proved to be a new range of topical issues from earth and environmental sciences highly appreciated by the participants.

    Maternal stress during pregnancy may influence childhood growth and adiposity, possibly through immune/inflammatory programming. We investigated whether exposure to prenatal stress and methylation in inflammation-related genes were associated with childhood adiposity in 424 mother-child pairs in Mexico City, Mexico. A stress index was created based on four prenatally administered stress-related scales (Exposure to Violence, Crisis in Family Systems, State-Trait Anxiety Inventory, and Edinburgh Postnatal Depression Scale). We measured weight, height, body fat mass (BFM), percentage body fat (PBF), and waist circumference in early childhood (age range, 4-6 years). Body mass index (BMI) z scores were calculated according to World Health Organization standards. DNA methylation in gene promoters of tumor necrosis factor α, interleukin 8, and interleukin 6 (IL6) in umbilical cord blood were determined by pyrosequencing. An interquartile range increase in stress index (27.3) was associated with decreases of 0.14 unit in BMI z score (95% confidence interval [CI] = -0.28 to -0.005), 5.6% in BFM (95% CI = -9.7 to -1.4), 3.5% in PBF (95% CI = -6.3 to -0.5), and 1.2% in waist circumference (95% CI = -2.4 to -0.04) in multivariable-adjusted models. An interquartile range increase in IL6 methylation (3.9%) was associated with increases of 0.23 unit in BMI z score (95% CI = 0.06-0.40), 8.1% (95% CI = 2.3-14.3) in BFM, 5.5% (95% CI = 1.7-9.5) in PBF, and 1.7% (95% CI = 0.2-3.3) in waist circumference. Prenatal stress was associated with decreased childhood adiposity, whereas cord blood IL6 methylation was associated with increased childhood adiposity in Mexican children.

    Accurate models of soil moisture are vital for solving core problems in meteorology, hydrology, agriculture and ecology. The capacity for soil moisture modelling is growing rapidly with the development of high-resolution, continent-scale gridded weather and soil data together with advances in modelling methods. In particular, the GlobalSoilMap.net initiative represents next-generation, depth-specific gridded soil products that may substantially increase soil moisture modelling capacity. Here we present an implementation of Campbell's infiltration and redistribution model within the NicheMapR microclimate modelling package for the R environment, and use it to assess the predictive power provided by the GlobalSoilMap.net product Soil and Landscape Grid of Australia (SLGA, ∼100 m) as well as the coarser resolution global product SoilGrids (SG, ∼250 m). Predictions were tested in detail against 3 years of root-zone (3-75 cm) soil moisture observation data from 35 monitoring sites within the OzNet project in Australia, with additional tests of the finalised modelling approach against cosmic-ray neutron (CosmOz, 0-50 cm, 9 sites from 2011 to 2017) and satellite (ASCAT, 0-2 cm, continent-wide from 2007 to 2009) observations. The model was forced by daily 0.05° (∼5 km) gridded meteorological data. The NicheMapR system predicted soil moisture to within experimental error for all data sets. Using the SLGA or the SG soil database, the OzNet soil moisture could be predicted with a root mean square error (rmse) of ∼0.075 m3 m-3 and a correlation coefficient (r) of 0.65 consistently through the soil profile without any parameter tuning. Soil moisture predictions based on the SLGA and SG datasets were ≈ 17% closer to the observations than when using a chloropleth-derived soil data set (Digital Atlas of Australian Soils), with the greatest improvements occurring for deeper layers. The CosmOz observations were predicted with similar accuracy (r = 0.76 and rmse of ∼0

    Full Text Available Abstract Background Geographic Information Systems (GIS are powerful communication tools for public health. However, using GIS requires considerable skill and, for this reason, is sometimes limited to experts. Web-based GIS has emerged as a solution to allow a wider audience to have access to geospatial information. Unfortunately the cost of implementing proprietary solutions may be a limiting factor in the adoption of a public health GIS in a resource-constrained environment. Scalable Vector Graphics (SVG is used to define vector-based graphics for the internet using XML (eXtensible Markup Language; it is an open, platform-independent standard maintained by the World Wide Web Consortium (W3C since 2003. In this paper, we summarize our methodology and demonstrate the potential of this free and open standard to contribute to the dissemination of Expanded Program on Immunization (EPI information by providing interactive maps to a wider audience through the Internet. Results We used SVG to develop a database driven web-based GIS applied to EPI data from three countries of WHO AFRO (World Health Organization – African Region. The system generates interactive district-level country immunization coverage maps and graphs. The approach we describe can be expanded to cover other public health GIS demanding activities, including the design of disease atlases in a resources-constrained environment. Conclusion Our system contributes to accumulating evidence demonstrating the potential of SVG technology to develop web-based public health GIS in resources-constrained settings.

Compound organic of mercury in the foods they are absorbed in 95% in the alimentary canal and stored in the fatty fabric and the brain. The biological period for compound organic of mercury it ascends to several (1 -18) years. While in a mature brain they are only attacked and damaged, partly in irreversible form his structure already existent, in a brain of a boy the mercury can cause that these structures not even go being formed. In the children the chronic absorption is cause of the Feer illness. If those affected are mature with similar symptoms it is also spoken of micro-mercuryalism. The clinical scheme is manifested p. e.g. in the non acceptance of walking, to be stopped and to sit down, without appetite behavior and of bad humor, apathy, muscular pains and of the articulations, loss appetite and of weight. The adults also present audition problems and tremors. In the world environment the mercury causes more dangers for the health of what was supposed until recently. This was of an alarming study of the program of the environment of the United Nations (UNEP) Some scientists suppose that for this reason annually only in USA 300000 recently born they take a bigger risk for cerebral damages. This implies from problems in the learning until damages in the nervous system. Most of the miners know about the dangers for the health caused by the mercury. However their careless handling is usually more the rule that the exception, since the effects then no longer reversible they are not immediate, but for the alone accumulation they are manifested in the course of the time, even after years. The technical alternatives in front of the use of mercury in the extraction of gold exist. But many times they require a bigger capital investment and in their handling they are more complex.

    Enacting Environments is an ethnography of the midst of the encounter between corporations, sustainable development and climate change. At this intersection 'environmental management' and 'carbon accounting' are put into practice. Purportedly, these practices green capitalism. Drawing on fieldwork...... of day-to-day practices of corporate environmental accountants and managers, Ingmar Lippert reconstructs their work as achieving to produce a reality of environment that is simultaneously stable and flexible enough for a particular corporate project: to stage the company, and in consequence capitalism......, as in control over its relations to an antecedent environment. Not confined to mere texts or meetings between shiny stakeholders co-governing the corporation – among them some of the world's biggest auditing firms, an environmental non-governmental organisation (NGO) and standards – control is found...

    In this thesis, we implemented a way of programming by means of gaming accessories. The main reason is that to show a diferent way of developing programs, because vast majority of programers are using two input / output devices: keyboard and mouse. These two devices have become standard and will definitely remain so in the future. For our implementation, we used high-level programming language Java and NetBeans integrated development environment. The program is actually a ...

    Full Text Available The purpose of this research is the identification of a paradigm which fixes the basic concepts and the type of logical relationships between them, whereby direct, govern and evaluate choises on new technologies. The contribution is based on the assumption that the complexity of knowledge is correlated with the complexity of the learning environment. From the existence of this correlation will descend a series of consequences that contribute to the definition of a theoretical construct in which the logical categories of learning become the guiding criteria on which to design learning environments and, consequently, also the indicators on by which to evaluate its effectiveness.

    The maternal-fetal environment plays an important role in developmental programming of adult disease. Metabolic and hormonal dysfunction during human fetal development accompanies gestational diabetes as a common occurrence in polycystic ovary syndrome (PCOS) mothers, while human fetal androgen excess from congenital adrenal hyperplasia or virilizing tumors precedes PCOS-like symptoms after birth. To date, clinical studies of infant blood levels at term have yet to confirm that human fetal an...

    Power generation from radioisotopes is one of the major applications of nuclear energy for peaceful purposes and is in practice in over twenty countries including India. Other well-known applications of radioactive substances are in medicine, industry, scientific and industrial research programs, and nuclear weapons. The only serious disadvantage with the radioisotopes and their waste products is the constant release of radiation energy which contaminates the environment and endangers the life. An attempt has been made to identify the major sources of radioactivity in the environment and assess its potential impact on the environment. Recent developments in safety measures for prevention of contamination and control of radioactivity and in radioactive wastes management are also discussed.

    Full Text Available According to United Nations Environment Programme (UNEP, ensuring a clean and healthy environment will provide multiple benefits to society and economy. Sustainable production, followed by appropriate management of industrial and agricultural waste, will protect and enhance biodiversity and ecosystem services. To achieve this objective, specific policies must be put in place and specific actions performed for making a low-carbon and resource-efficient economy with reduced production of petrol-derived goods. The aim of the study has been to produce effective and safe anti-age beauty masks made of non-woven tissues based on the use of chitin nanofibril (CN and nanolignin (LG, obtained from crustaceans and plant biomass, respectively. To this purpose, nanoparticles and electrospun fibres have been characterized by Dynamic Light Scattering and SEM, while the safeness and effectiveness of the obtained tissues was verified in vitro on a culture of keratinocytes and fibroblasts, and controlled in vivo by expert dermatologists on 30 volunteer photo-aged women, by subjective and objective bioengineered methods. The in vitro results have shown that the beauty masks have no toxic effects on the viability of keratinocytes and fibroblasts treated by the Dimethyl Tetrazole (MTT method, and exhibit a decreased expression of cytokines, playing a central role in the regulation of immune and inflammatory responses in premature aging and environmental assaults. The reparative and antiaging effectiveness of these innovative beauty masks have been also verified on the release of Metallo Proteinase I (MMP-1 and the increased synthesis of collagen type I, reduced in skin aging. The first preliminary in vivo results, obtained by engineering methods, have confirmed the protective and rejuvenating activity shown by the in vitro study conducted on 30 voluntary women exhibiting signs of photoaging. The raw materials used are of natural origin being also respectful of the

    According to the Millennium Development Goals, managing the environment is considered an integral part of the global development process. The main purpose of the IAEA's environment laboratories is to provide Member States with reliable information on environmental issues and facilitate decision making on protection of the environment. An increasingly important feature of this work is to assess the impact of climate change on environmental sustainability and natural resources. The IAEA's environment laboratories use nuclear techniques, radionuclides, isotopic tracers and stable isotopes to gain a better understanding of the various marine processes, including locating the sources of pollutants and their fate, their transport pathways and their ultimate accumulation in sediments. Radioisotopes are also used to study bioaccumulation in organisms and the food chain, as well as to track signals of climate change throughout history. Natural and artificial radionuclides are used to track ocean currents in key regions. They are also used to validate models designed to predict the future impact of climate change and ocean acidification. The laboratories study the fate and impact of contamination on a variety of ecosystems in order to provide effective preventative diagnostic and remediation strategies. They enhance the capability of Member States to use nuclear techniques to understand and assess changes in their own terrestrial and atmospheric environments, and adopt suitable and sustainable remediation measures when needed. Since 1995, the IAEA environment laboratories have coordinated the international network of Analytical Laboratories for the Measurement of Environmental Radioactivity, providing accurate analysis in the event of an accident or an intentional release of radioactivity. In addition, the laboratories work alongside other organizations, such as UNESCO, the IOC, UNEP and the EC. The laboratories collaborate with Member States through direct involvement with

    Changes to the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) occurred in 2009 when supplemental foods offered through the programme were updated to align with current dietary recommendations. The present study reports on a new index developed to monitor the retail environment's adoption of these new food supply requirements in New Orleans. A 100-point WIC Availability Index (WIC-AI) was derived from new minimum state stocking requirements for WIC vendors. A sample of supermarkets, medium and small food stores was assessed in 2009 before changes were implemented and in 2010 after revisions had gone into effect. WIC-AI scores were utilized to compare differences in meeting requirements by store type, WIC vendor status and year of measurement. Supermarkets, medium and small WIC and non-WIC food stores in New Orleans, Louisiana, USA. At baseline supermarkets had the highest median WIC-AI score (93·3) followed by medium (69·8) and small food stores (48·0). Small WIC stores had a higher median WIC-AI score at baseline than small non-WIC stores (66·9 v. 38·0). Both medium and small WIC stores significantly increased their median WIC-AI scores between 2009 and 2010 (P<0·01). The increased median WIC-AI score in small food stores was largely attributed to increased availability of cereals and grains, juices and fruit, and infant fruit and vegetables. The WIC-AI is a simple tool useful in summarizing complex food store environment data and may be adapted for use in other states or a national level to inform food policy decisions and direction.

    Full Text Available Spreadsheet management is a border-land between office applications and programming, however, it is rather communicated that spreadsheet is nothing more than an easily handled fun piece. Consequently, the complexity of spreadsheet handling, the unprepared end-users, their problem solving abilities and approaches do not match. To overcome these problems we have developed and introduced Sprego (Spreadsheet Lego. Sprego is a simplified functional programming language in spreadsheet environment, and such as can be used both as introductory language and the language of end-user programmers. The essence of Sprego is that we use as few and simple functions as possible and based on these functions build multilevel formulas. With this approach, similar to high level programming, we are able solve advanced problems, developing algorithmic skills, computational thinking. The advantage of Sprego is the simplicity of the language, when the emphasis is not on the coding but on the problem. Beyond that spreadsheets would provide real life problems with authentic data and tables which students are more interested in than the artificial environment and semi-authentic problems of high level programming languages.

    Aside from the atomic bomb attacks in 1945, the experience of radioactive contamination of human environment was the exposure of a tuna fishing boat to the radioactive fallout of a hydrogen bomb test explosion at Bikini atoll in March, 1954. Thereafter, radioactivity was frequently detected in fishes in central Pacific Ocean. Radioactivity was also detected in rain, which resulted in the contamination of agricultural products. Due to the great concern of general public for the radioactivity in food materials, the government initiated the national program of radioactivity surveillance. Since then, the fallout radioactivity due to nuclear test explosions was the main object surveillance in 1950s and 1960s, but the program was gradually expanded to include natural radiation, the artificial radioactivity due to the peaceful uses of nuclear energy and other special programs. The history of the radioactive contamination of environment, natural radiation, medical exposure, the radioactive fallout due to nuclear tests, nuclear power generation and the Chernobyl accident are reported.

    Lack of classroom space is a common problem for many hospital-based nurse educators. This article describes how nursing educators in one institution redesigned fixed classroom space into a flexible learning center that accommodates their various programs. Using the nursing process, the educators assessed their needs, planned the learning environment, implemented changes in the interior design, and evaluated the outcome of the project. The result was a learning environment conducive to teaching and learning.

    The international symposium on Isotope Hydrology was held in May 2003. This symposium marked the 40th anniversary of these quadrennial IAEA symposia first convened in 1963 and was one of the contributions of the Agency to the International Year of Freshwater. The symposium drew a record 274 participants from 69 countries. The state-of-the-art in isotope techniques and their application to water resources management were reviewed, confirming that groundwater sustainability issues remain the mainstay for isotope applications, while application in climate modelling and watershed management is also becoming increasingly important. Water cycle research is one of the key elements of the Johannesburg Plan of Implementation resulting from the World Summit on Sustainable Development. As a result of the Agency's efforts since 2001, isotopes are now being integrated into the GEWEX (Global Energy and Water Cycle Experiment) project of WMO/ICSU's World Climate Research Programme project. An IAEA/GEWEX workshop evaluated the potential means of integrating precipitation isotope data in moisture source tracing models and, as a first step, initiated an international inter-comparison of the isotopic modules in different global circulation models. Two new research coordinated projects (CRPs) were recently initiated aimed at investigating the use of isotopes for groundwater sustainability assessment by characterizing the age of river baseflow, and for improved quantification of evaporation-transpiration fluxes by measuring isotopes in air, leaf and stem moisture. Each of these evinced tremendous response for participation by more than 20 research groups. Partnerships with other international agencies and programmes were further strengthened. A strong link was established with the UNEP/Global Environment Monitoring System/Water Programme (GEMS/Water) through a joint project to undertake inter-laboratory comparison exercises for water chemistry aimed at improving the quality of chemical
