  1. Potential for joint implementation (activities implemented jointly in Kenya)

    Mwandoto, Stephen H. [Kenya Meteorological Department, Nairobi (Kenya)

    1999-07-01

    Kenya has ratified the United Framework Convention for Climate Change (UNFCCC) which entered into force on March 21st 1994 and therefore the country is free to participate in Joint Implementation (AIJ) projects. All development projects, activities and services utilise natural resources in one form or another. The technology used in the local industry therefore must be made as efficient as possible so as to provide a much higher output of saleable goods and services from the same resource base in order to reduce wastes in the form of pollutants in gaseous, liquids or solid forms. The 8th Kenya National Development Plan, the 1996 Sessional Paper on Industrialisation, the National Environmental Action Plan and the draft National Environmental policy paper have clearly defined the policy initiatives on acquisition of efficient manufacturing production processes to protect the resource base. What is now required is the implementation of those policy initiatives by application of the best available and affordable technology to maximise trade and investments. In this paper, the potential for investments in alternative energy technologies and energy efficiency in Medium and Small Scale enterprises in Kenya is discussed. (Author)

  2. Survey of Joint Implementation activities in China; Chugoku ni okeru kyodo jisshi katsudo kanren chosa

    1997-03-01

    It is a large task for Japan to positively promote the Joint Implementation activities related to the United Nations Framework Convention on Climate Change. Rapid increase in the emission of greenhouse-effect gases, especially CO2, is predicted in China with remarkable economic growth and population of 1.2 billion. It is essential to promote the Joint Implementation activities in China. In this survey, framework, organization, problems and tasks were investigated to effectively promote the Joint Implementation activities in China. Construction of framework for the real Joint Implementation activities has been proposed. Current problems for promoting the Joint Implementation activities in China are that the distinct guideline for the Joint Implementation is not established in the government, that the receiving system including receiving, planning and arranging sections is not established, and that the burden problems for the costs of project evaluation, data acquisition, monitoring, and verification are not solved. 5 refs., 21 figs., 6 tabs.

  3. Potential areas for AIJ [Activities Implemented Jointly] projects in Kenya

    Omulo, Monica A. [Climate Network Africa, Nairobi (Kenya)

    1998-09-01

    This paper identifies three sectors where AIJ could bring tangible benefits to Kenya as well as massive benefits to the environment in terms of greenhouse gas emissions reduction. The energy sector is one of the potential areas for AIJ activities. Kenya has few developed domestic energy sources, despite the potential, little attention has been paid in the past to the potential for domestic energy from existing renewable resources. There is potential for exploration of existing renewable energy resources using decentralized small scale renewable energy technologies based on wind and solar power. The other area is the transport sector which has a wide variety of proven options including increasing affordable public transport, by discouraging private car use, shifting freight from road to rail. The possible participants include local and international private industries and Government. For instance, the private industry could set up urban car clinics to fine-tune engines for more efficient operations, raise public awareness, save fuel and foreign exchange. The third potential sector for AIJ is the production industry. This requires modernization of the polluting industries using environmentally friendly technologies. There is great potential for the sectors to contribute to greenhouse gas emissions reduction. Kenya should therefore take advantage of the development potential offered in AIJ/JI by focusing attention primarily on sectors such as energy, transport, and industry and promote science and technology in these areas.

  4. Ruminant methane reduction through livestock development in Tanzania. Final report for US Department of Energy and US Initiative on Joint Implementation--Activities Implemented Jointly

    Livingston, Roderick

    1999-07-01

    This project was designed to help develop the US Initiative on Joint Implementation activities in Eastern Africa. It has been communicated in meetings with representatives from the Ministry of Environment of Tanzania and the consultant group that developed Tanzania's National Climate Change Action Plan, the Centre for Energy, Environment, Science and Technology, that this project fits very well with the developmental and environmental goals of the Government of Tanzania. The goal of the Activities Implemented Jointly ruminant livestock project is to reduce ruminant methane emissions in Eastern Africa. The project plans a sustainable cattle multiplication unit (CMU) at Mabuki Ranch in the Mwanza Region of Tanzania. This CMU will focus on raising genetically improved animals to be purchased by farmers, developmental organizations, and other CMUs in Tanzania. Through the purchase of these animals farmers will raise their income generation potential and reduce ruminant methane emissions.

  6. Practical aspects of joint implementation

    Article 4, 2a of the UN Framework Convention on Climate Change states the possibility of joint policies of different countries to achieve national greenhouse gas reduction commitments (Joint Implementation). The cost of reducing greenhouse gas emissions can be reduced drastically if industrialized countries shift abatement activities to developing countries as marginal cost of reduction is much higher in the former countries. In this way economic efficiency of abatement measures can be raised to the point where marginal cost is equal all over the world. At the Conference of the Parties in Berlin in March 1995, criteria for Joint Implementation are to be established. The paper discusses possible forms of Joint Implementation and develops criteria

  7. CO2 emission baseline construction for Activities Implemented Jointly reporting in heat production sector

    The present work is dedicated to the calculation method for the reduction of greenhouse gases emissions developed within the Joint Implementation projects of the Climate Change Framework Convention based on the case study of Estonian heat supply in 1990ies. Data of the Estonian Statistical Office and data of the Estonian Energy Research Institute on the use of fuels and heat production in recent decade have been used in the paper. CO2 emissions by the types of fuels have been calculated and emission reduction trend for the whole country is given based on the detailed statistics of the consumption of various fuels. This has been taken for a basis for calculating the decrease of CO2 emissions as a result of Joint Implementation pilot phase implementation between Sweden and Estonia. Baseline of CO2 emission has been constructed, considering the changes in the structure of fuel consumption as well as the forecasts of energy sector as whole. Constructed by authors of present paper baseline has been used by donor country for reporting to U N FCCC Secretariat in Bonn. Decision on credit sharing and emission trading between parties to Climate Convention has not been made yet, but Estonia and Sweden are ready for that looking forward to decisions to be made during the next conference of parties, COP 6. Authors do hope sincerely that the present contribution will elaborate to the solutions for future activities between two neighbours. (author)

  8. The joint implementation mechanisms (MOC)

    The aim of the joint implementation mechanisms (MOC) is aims to favor the fight against the climatic change, by the implementing of activities, technologies and appropriate techniques emitting less greenhouse gases in south countries and by the possibility of reducing the greenhouse gases emissions for a more economical cost. This guide brings a practical assistance to the projects set-up: the possible concerned projects, the formalization of the project, the methodology, the involvement of the carbon credits in the project financing.

    1996-03-01

    Elaboration of the evaluation guidelines for activities implemented jointly (AIJ) was researched to prevent the earth from warming. AIJ is the means to globally promote countermeasures against global warming cost-effectively by optimally combining every country`s technology, know-how and fund. AIJ was established in the 1st Conference of the Parties (COPI) of the United Nations Framework Convention on Climate Change in March, 1995. The pilot phase of AIJ is first carried out by voluntary workers jointly with developing countries under the agreement of the parties. The current situation of activities is reported in COPI as materials for evaluation of AIJ. To promote AIJ, elaboration of the evaluation guidelines for AIJ Japan program is also necessary for Japan. This research arranged the contents of the evaluation guidelines and the method of classifying projects for AIJ Japan program, and carried out some case studies of promising projects to reduce greenhouse gas emission for future proposal. 3 figs., 31 tabs.

  10. The Challenge of Limiting Greenhouse Gas Emissions Through Activities implemented Jointly in Developing Countries: A Brazilian Perspective

    La Rovere, E.L.

    1998-11-01

    This paper addresses, from the Brazilian perspective, the main problems with Joint Implementation/Activities Implemented Jointly (JI/AIJ) between industrialized (Annex I) and developing (non-Annex I) countries, as defined by the United Nations Framework Convention on Climate Change (UNFCCC). Four possible GHG emissions abatement measures are presented for Brazil: forest protection, reforestation projects for carbon sequestration or charcoal manufacturing, use of ethanol produced from sugar cane as a car fuel, and electrical energy conservation through an increase in end-use efficiencies. These four case studies form the basis of a discussion regarding the validity of developing countries' concerns about JI/AIJ. Recommendations are offered for overcoming the present shortcomings of JI/AIJ in developing countries. The primary conclusion is that Annex I countries' funding of JI/AIJ projects in developing countries in return for GHG emissions credits is not the best means to implement the UNFCCC. However, JI/AIJ projects can be a productive means of preventing global climate change if combined with other measures, including GHG emissions reduction targets for all countries involved in JI/AIJ projects and limits on the percentage of industrialized countries' emissions reductions that can be met through projects in developing countries.

  11. Renewable energy supply systems in Indonesia. The Activities Implemented Jointly (AIJ) project of the E7 initiative. A case study

    Betz, R.

    1999-02-01

    The Renewable Energy Supply System Project, short RESS project, is an Activities Implemented Jointly (AIJ) project carried out by the E7-Initiative combining eight of the world's largest electric utilities of G7 countries (RWE AG Germany is the main coordinator of this project). The first part of the chapter gives a description of the project's background, organisation and different components including the financial aspects and the present state of implementation of the RESS project. The second part presents the evaluation of the project: on the one hand primary objectives will be analysed from the investor's view, on the other hand secondary objectives from a more development co-operation and political point of view. In the final part general problems and especially problems relevant to the further development of the Clean Development Mechanism (CDM) will be summed up. (orig.)

  12. Russian energy efficiency projects: lessons learnt from Activities Implemented Jointly pilot phase

    Russia needs to improve the efficiency of energy. Failure to do so will retard the economic recovery of the country, but the energy sector is lacking both domestic and foreign investments. JI projects could provide the underfinanced Russian energy sector with additional investments. AIJ pilot project experiences provide an overview of the potential difficulties for future JI projects. Institutional problems were the most important category. Most of these problems remain, and the lack of ratification of the Kyoto Protocol by Russia has formed a new very significant barrier. Implementation level problems caused some problems to AIJ projects, but they are likely to have less impact on the better prepared JI projects. The character of funding-related problems has changed: for AIJ projects the main problem was that emission reductions could not be credited, whereas future JI projects will experience more competition in the Kyoto market where the overall investment climate and the availability of local cofunding are more relevant. Therefore, the unfinished economic and energy sector reforms currently discourage JI investments. The project experiences so far have been dismal, and if Russian policy-makers cannot improve this performance, only few JI projects can be expected in the future

  13. US initiative on joint implementation: An overview

    Dixon, R.K. [Initiative on Joint Implementation, Washington, DC (United States)

    1996-12-31

    More than 150 countries are now Party to United Nations Framework Convention on Climate Change, which seeks as its ultimate objective, to stabilize atmospheric concentrations of greenhouse gases at a level that would prevent dangerous human interference with the global climate system. As a step towards that goal, all Parties are to take measures to mitigate greenhouse gas emissions and to promote cooperation in the development and diffusion of technologies and practices that control or reduce emissions and enhance sinks of greenhouse gases. In the U.S. view, efforts between countries or entities within them to reduce net greenhouse gas emissions undertaken cooperatively, termed joint implementation (JI), holds significant potential both for reducing the threat of global climate change and for promoting sustainable development. To develop and operationalize the JI concept, the U.S. launched its Initiative on Joint Implementation (IJI) in October, 1993, and designed a program to attract private sector resources and to encourage the diffusion of innovative technologies to mitigate greenhouse gas emissions. The goals of U.S. IJI complement the principles of Decision 5, First Conference of the FCCC Parties, establishing an Activities Implemented Jointly pilot phase.

    The pilot phase of the activities implemented jointly (AIJ) was approved in 1995 in the 1st Conference of the Parties (COPI) of the United Nations Framework Convention on Climate Change to reduce greenhouse gas emission. In order to promote the AIJ Japan program smoothly, some practical examples in every preceding country and the situations and demands of Asian countries were researched. It was confirmed that since larger cost-effectiveness is achieved just in countries lower in emission control cost, AIJ can enhance the cost-effectiveness and promote environmental technology transfer. Japanese government had studied establishment of the framework for AIJ, and decided the basic framework of the AIJ Japan program in 1995. The government also approved the evaluation guidelines of this program which include confirmed and considered matters necessary for government offices related to this program to evaluate and approve each project.

    Rapid economy growth has been observed in Asia including Japan. On the other hand, problems of population and environment grew even worse with the economic growth. Especially, China is the second CO2 emission country in the world. Large energy demand is still forecasted with its economic growth in the future. It is well-known that the energy consumption per unit GDP is very large. Therefore, it is very significant to promote the activities implemented jointly with China for mitigating the emission of greenhouse gases including CO2, which provides a significant meaning for solving global environmental issues as well as for improving regional environmental issues. It is necessary for the above to recognize the appropriate current situations and to promote the activities implemented jointly suitable for the country. Based on the discussions and information exchanges about environmental issues with staffs concerning environmental policies and scientists as well as the field surveys, methods for the activities implemented jointly were investigated to provide some proposals. 4 figs., 8 tabs.

    More than 150 countries are now Party to the United Nations Framework Convention on Climate Change (FCCC), which seeks, as its ultimate objective, to stabilize atmospheric concentrations of greenhouse gases at a level that would prevent dangerous human interference with the climate system. As a step toward this goal, all Parties are to take measures to mitigate climate change and to promote and cooperate in the development and diffusion of technologies and practices that control or reduce emissions and enhance sinks of greenhouse gases. In the US view, efforts between countries or entities within them to reduce net greenhouse gas emissions undertaken cooperatively--called joint implementation (JI)--holds significant potential both for combating the threat of global warming and for promoting sustainable development. To develop and operationalize the JI concept, the US launched its Initiative on Joint Implementation (USIJI) in October 1993, and designed the program to attract private sector resources and to encourage the diffusion of innovative technologies to mitigate climate change. The USIJI provides a mechanism for investments by US entities in projects to reduce greenhouse gas emissions worldwide and has developed a set of criteria for evaluating proposed projects for their potential to reduce net GHG emissions.

  17. Joint implementation: Biodiversity and greenhouse gas offsets

    Cutright, Noel J.

    1996-11-01

    One of the most pressing environmental issues today is the possibility that projected increases in global emissions of greenhouse gases from increased deforestation, development, and fossil-fuel combustion could significantly alter global climate patterns. Under the terms of the United Nations Framework Convention on Climate Change, signed in Rio de Janeiro during the June 1992 Earth Summit, the United States and other industrialized countries committed to balancing greenhouse gas emissions at 1990 levels in the year 2000. Included in the treaty is a provision titled “Joint Implementation,” whereby industrialized countries assist developing countries in jointly modifying long-term emission trends, either through emission reductions or by protecting and enhancing greenhouse gas sinks (carbon sequestration). The US Climate Action Plan, signed by President Clinton in 1993, calls for voluntary climate change mitigation measures by various sectors, and the action plan included a new program, the US Initiative on Joint Implementation. Wisconsin Electric decided to invest in a Jl project because its concept encourages creative, cost-effective solutions to environmental problems through partnering, international cooperation, and innovation. The project chosen, a forest preservation and management effort in Belize, will sequester more than five million tons of carbon dioxide over a 40-year period, will become economically selfsustaining after ten years, and will have substantial biodiversity benefits.

  18. Joint implementation in the climate change convention

    The United Nations Climate Change Convention offers developed countries the possibility to realize a part of their obligations elsewhere via financing of emission reduction activities. This so-called joint implementation (JI) enlarges the effectiveness of the international climate change policy. It is assumed that the marginal costs of the emission reductions differ between countries. The application of JI has benefits, but also bears risks. With regard to potential nett benefits and costs/risks it is of interest to distinguish between micro-effects (on a project level), macro-effects (on a national level) and global effects, focusing on JI between OECD countries and developing countries. Five comments on this tripartite are made: (1) it is important to gain insight in the JI potential; (2) JI can contribute to projects of a high development priority; (3) there is a chance that parties, involved in JI, claim more reductions (credits) than take place in reality (double counting); (4) there exists the risk of a delay of technological progress; and (5) the danger exists that JI causes a minor stimulus for developing countries to accept emission reduction obligations. A functional JI-system demands criteria that limits the risks and optimize the benefits. The main criteria concern verification of realized emission reductions; an acceptable balance between measures in one's own country and JI, for which three mechanisms are briefly discussed (partial credit entry, funds, and separated targets); and additionality of JI-financing. Side criteria are the monitoring, verification and control of the possession of the credits. Finally attention is paid to the role of the government in JI and further developments and chances for JI. 7 refs

    The Kyoto Protocol allows some flexibility in the implementation of methods for achieving the goal, such as emission trading, activities implemented jointly (AIJ) among advanced countries, construction of clean development mechanisms (CDM) with developing countries, etc., and Japan intends to positively make use of them for the achievement of the goal. For China, who holds second place in the list of greenhouse gas emitting countries in the world, the promotion of CDM is quite important. With the situation taken into consideration, interaction was effected with Chinese officers and scientists of government agencies and academic institutes involved in environmental matters, and researches were conducted. Views and information were exchanged regarding environmental problems and, after on-site investigations, researches were conducted and suggestions were presented as to how AIJ and CDM should be. The suggestions covered Chinese policies toward AIJ and CDM, current state of AIJ projects in China and systems for their promotion, means for enhancing such projects, and discovery of candidates for AIJ and CDM project application.

  20. Joint implementation: methodology and policy considerations

    The focus of the present paper is on joint implementation (JI) projects between countries in Western and Eastern Europe and especially on the problems of constructing credible references (baselines). A number of the present EU countries are anticipated to have severe problems in meeting their greenhouse gas reduction commitments and they have already announced that they shall take advantage of JI in this connection. As stated in the Kyoto Protocol, JI emission reductions must be real and measurable. However, in most cases the reductions obtained by a JI project do not occur at the project site but elsewhere in the energy system. Therefore, when a number of JI projects are implemented concurrently and other changes in the energy system take place over time, there is no way to measure the reductions obtained by individual projects. Because the emission reduction obtained is a property of the entire energy system, it cannot be estimated a priori on the basis of a project baseline alone. A baseline must refer to the national energy system of which the project is a part. It is argued in this paper that baselines should be derived from national energy systems databases and models, which serve to ensure that JI projects effectively contribute to the fulfillment of the Kyoto Protocol objectives. In addition, they should provide governments with comprehensive energy information systems needed to address long-term climate mitigation and energy demand and supply issues in a rational, least-cost manner. Compared to other climate mitigation costs and the costs of failure to meet the Kyoto commitments the costs involved in the preparation of the databases needed and the implementation of systems analysis and documentation programs will be small. If these costs are carried by national governments, the investors in JI projects will benefit from lower transaction costs

  1. Joint implementation and the question of 'additionality' - a proposal for a pragmatic approach to identify possible joint implementation projects

    The theoretical concept of joint implementation and the idea of reducing greenhouse gas emissions where costs are least is still charming and - at least for economists - no revolution. However, one of the most critical aspects regarding joint implementation is the question of 'additionality'. Some argue that a 'real' joint implementation project may not have any commercial value at all, others propose that the value of emissions reduction credits shall bring about a positive return on investment where otherwise it would have been negative. The present paper states that there is no feasible option to divide projects into joint implementation and non-joint implementation candidates regarding their financing. The result is that any project which brings about real and measurable environmental and social benefits should be regarded as a possible joint implementation project, be it a pure donation or a highly profitable private investment. (Author)

  2. Joint implementation. Strategic reactions and possible remedies

    This paper investigates the promising proposal of Joint Implementation (R) to mitigate greenhouse gas emissions. This was ultimately the only concrete outcome of the Conference on Climate Change in Berlin, albeit restricted to a pilot phase. The basic idea, given the public's awareness of global warming, sounds economically plausible: The industrialized countries, the only ones required to stabilize and lower carbon emissions, can search for cheaper reductions of greenhouse gas emissions in developing countries and economies in transition. However, this proposal leads to strategic reactions by developing countries reinforced by the fact that this cheating coincides with the interest of the industrialized country. In short, this proposal will lead to cheating (given asymmetric information) and will thus produce largely faked reductions in emissions. On the constructive side, an efficient mechanism retaining the spirit of JI is derived, which deters strategic reactions. This differs from a usual principal-agent problem through an additional hierarchical layer: a global authority (e.g. Conference of Parties on Climate Change), an industrialized country and a developing country. The unavoidable loss that is even associated with an optimal scheme due to strategic, behavioural reality (the first best optimum is unattainable, except at the top) leads, of course, to much less glamorous predictions in emission reductions. Moreover, the implicit subsidization scheme focuses favours on already 'efficient' partners. 39 refs

  3. Mexico joins the venture: Joint Implementation and Greenhouse Gas Emissions

    Imaz, M.; Gay, C.; Friedmann, R.; Goldberg, B.

    1998-11-01

    Joint Implementation (JI) and its pilot phase of Activities Implemented Jointly (AIJ) are envisioned as an economic way of reducing global emissions of greenhouse gases. This paper draws upon the Mexican experience with AIJ to identify Mexican concerns with AIJ/JI and proposed solutions to these. Three approved Mexican AIJ projects (Ilumex, Scolel Te, and Salicornia) are described in detail. The Ilurnex project promotes the use of compact fluorescent lamps in Mexican homes of the States of Jalisco and Nuevo Leon, to reduce electric demand. Scolel Te is a sustainable forest management project in Chiapas. Salicornia examines the potential for carbon sequestration with a Halophyte-based crop irrigated with saline waters in Sonora. These three projects are reviewed to clarify the issues and concerns that Mexico has with AIJ and JI and propose measures to deal with them. These initial Mexican AIJ projects show that there is a need for creation of standard project evaluation procedures, and criteria and institutions to oversee project design, selection, and implementation. Further JI development will be facilitated by national and international clarification of key issues such as additionality criteria, carbon-credit sharing, and valuation of non-GHG environmental and/or social benefits and impacts for AIJ projects. Mexico is concerned that JI funding could negatively impact official development assistance or that OECD countries will use JI to avoid taking significant GHG mitigation actions in their own countries. The lack of carbon credit trading in the AIJ stage must be removed to provide useful experience on how to share carbon credits. National or international guidelines are needed to ensure that a portion of the carbon credits is allocated to Mexico.

    In order to positively promote the activities implemented jointly (AIJ) of the United Nations Framework Convention on Climate Change, the AIJ workshop acting in contact with Asia/Pacific countries, in particular, Chine having large effect on global environmental pollution was researched preliminarily. AIJ approved in the convention is the effective means to promote measures against global warming cost-effectively by optimally combining every developed country`s technology, know-how and fund. Distribution of the credit for greenhouse gas emission reduction by AIJ is unsolved because of the disagreement of views between developed and developing countries. The pilot phase of AIJ projects is carried out by voluntary workers jointly with developing countries until establishment of international rules. In fiscal 1995, the following were studied: the framework necessary for AIJ between Japan and China, the organization for promoting concrete AIJ projects, and the means to create the reliance of China for AIJ projects. 6 refs., 10 figs.

    Joint Implementation (JI) is a potentially powerful instrument of climate policy that could lead to a high amount of additional financial flows to developing countries. Nevertheless, many NGOs and developing country representatives are very skeptical about JI and fear that it would not take into account development priorities and create new kinds of dependence on industrial countries. Therefore, developing countries and industrial countries found a compromise at the Berlin Conference of the P...

  7. Domestic climate regimes and incentives for private sector involvement in joint implementation

    NONE

    1997-12-31

    This report analyses how effective incentive structures can be put in place for private sector involvement in pilot projects (AIJ, Activities Implemented Jointly) and, in due time, joint implementation (JI). Due to the short time record of AIJ/JI experience, lessons are drawn from other related policy areas: studies of public/private interface in environmental- and climate policy in the Netherlands, USA, Norway and Costa Rica. The report concludes with status and prospects for private sector incentives in the pilot phase and then provides lessons and proposals for such incentives in a more mature and ambitious JI regime with crediting. 22 refs.

  8. Joint Implementation Analysis: A Case Study of the Japan-China Coke Dry Quenching (CDQ) Project

    2000-01-01

    One of the key issues for "Joint Implementation" is how to define a plausible baseline, a necessary benchmark for calculating net Greenhouse Gases (GHGs) emission reductions through a comparative approach. Based on a thorough case study of the China-Japan Coke Dry Quenching (CDQ) project, the first approved pilot project in China under the "Activities Implemented Jointly" (AIJ) framework, the paper not only describes in detail the complete procedure of baseline definition of the case project, but also discusses its approach to baseline determination. Furthermore, cost-benefit analysis of GHGs mitigation is conducted according to the baseline. This empirical case study, based on real AIJ project data, will be beneficial for the development of future projects under Kyoto mechanisms such as "Clean Development Mechanism" and "Joint Implementation".

  10. DOD-DOE Workshop on Joint Energy Activities

    None

    1980-01-01

    The general conditions for DOD-DOE interactions were delineated in an October 1978, Memorandum of Understanding (MOU) that identified two basic goals: improving energy efficiency and availability within DOD, and utilizing DOD and DOE expertise and facilities to carry out projects of mutual interest. There has been considerable interaction between DOD and DOE, including a number of proposed joint initiatives but a systematic and coordinated approach for nurturing, maintaining, and expanding these relationships has not been developed. A DOD-DOE Workshop on Joint Energy Activities was held on March 10-12, 1980. The workshop was structured into five working groups - Mobility Fuels, Conservation, Fossil Fuels for Fixed Facilities, Solar and Renewable Energy Sources, and Special Projects - with DOD and DOE cochairmen for each. Over a hundred DOD and DOE management, program, and policymaking representatives were brought together by the workshop Steering Committee to identify specific programs for inclusion in an overall plan for implementing the MOU and to deal with fundamental issues and problems of maintaining future communications. The workshop accomplished its goals, these being to: (1) improve communication among the appropriate key DOD and DOE personnel at all levels and promote information exchange; (2) review ongoing and already-proposed joint DOD and DOE programs; (3) initiate a coordinated, systematic effort to establish joint DOD-DOE energy-security programs; and (4) propose specific programs and projects of mutual interest for inclusion in a follow-on joint-implementation plan.

  11. Joint Implementation, Clean Development Mechanism and Tradable Permits

    Nielsen, L.; Rose Olsen, K.

    2000-06-01

    This report deals with international environmental instruments aimed at a cost-effective reduction of greenhouse gas emissions. More precisely the instruments mentioned in the Kyoto Protocol, namely Joint Implementation (JI), the Clean Development Mechanism (CDM) and Tradable Permits (TP). The report describes the background for the international co-operation on reducing the greenhouse gases and the background for the instruments. How the instruments work in theory and what the practical problems may be. What agents' incentives are when they engage in JI or CDM, and how the initiation of the instruments can be organised. The institutional frameworks for JI, CDM and TP are discussed. The report describes how the Kyoto instruments and the Kyoto commitments interact with other instruments and describe distributive effects between countries. It is analysed how the use of CDM may influence the developing countries incentives to participate in the coalition of committed countries. In the concluding chapter some recommendations on the use of JI, TP and CDM are given. The recommendations are a kind of dialog with especially the Norwegian and Swedish reports on tradable permits. Some of the issues described in this main report are analysed in separate working papers. The working papers are collected in an appendix to the main report. (au)

  13. Joint implementation: a pioneer mechanism within the limits of emissions - Climate study nr 33

    The authors first notice that much has been written about the Clean Development mechanism defined in the Kyoto protocol, but also that the Joint Implementation mechanism has an always increasing importance. Provided that always more countries would adopt greenhouse gas emissions thresholds and the Joint Implementation after the Durban conference, they analyse the Joint Implementation mechanism operation in comparison with the Clean Development mechanism. They address the economic and environmental background of the Joint Implementation. Then, they analyse quantitative aspects of this mechanism, develop a model for the assessment of the potential offer in carbon credits. They discuss the qualitative aspects of the Joint Implementation mechanism: environmental integrity, double accounting, perceived concurrence of national climate policies. Case studies are presented (Russia, Ukraine, France, EU, etc.)

  16. Joint implementation, clean development mechanism and Tradable Permits. International regulation of greenhouse gases

    Nielsen, L.; Rose Olsen, K.

    2000-06-01

    A 'correct' accreditation is a key issue when evaluating Joint Implementation as a global environmental instrument. Problems mentioned in the literature on Joint Implementation - including the problem of additionality - are often relating to the problem of defining a correct accreditation. This paper lists some of these problems and lists some of the tools available to solve the reported problems of accreditation. The paper concludes that the institutional framework is crucial in defining what a correct accreditation is. It also concludes that different groups may have different interests in Joint Implementation, and that each of the reported problems may be a problem to some of the Joint Implementation interests groups but not to others. In designing the institutional framework for JI it is important to know the incentives and motivations of the different groups. The main part of the paper is an analysis of the basic incentives and motivations of the different Joint Implementation interest groups. This analysis can be used to weight the problems of Joint Implementation from an environmental perspective and from the perspective of cost effectiveness. (au)

  18. Joint implementation. Cost benefit analysis of global environmental care

    The strategy in SEP, the interconnected electricity supply undertaking of The Netherlands, for the limitation of greenhouse gas emissions is focussed on the implementation of cost-effective 'no regret' measures at home and abroad. Here, at present, SEP is concentrating on afforestation measures. Through a daughter organization called the FACE Foundation, SEP finances world-wide afforestation projects. FACE is able to take into account, forco-financing, the CO2 absorption capacity of these forests. These re-afforestation projects have proved to be a very cost-effective way of levelling out CO2 emissions in comparison with measures in The Netherlands. (orig.)

  19. A dynamic crediting regime for Joint Implementation to foster innovation in the long term

    Joint Implementation is a theoretically efficient instrument of a climate policy at least in the short run. This need not apply for the long run. Joint Implementation can reduce innovation in the industrialized countries because of reduced incentives for emission reduction. To realize short run efficiency gains and to avoid long run efficiency losses, we need a 'strategic' climate policy. This policy should start with full crediting of Joint Implementation allowing short-run efficiency gains which can foster technology transfer and thus lead to 'leapfrogging' by developing countries. Over time, the crediting ratio should be gradually reduced while domestic carbon taxes are raised. Experiences from the second oil shock have shown that energy-saving innovation is positively correlated to energy prices. Both, the reduced crediting and the raising domestic carbon tax, will therefore lead to long-run innovation. 7 figs., 2 tabs., 16 refs

    Full Text Available Abstract Background Parents and children joint activities are considered to be an important factor on healthy lifestyle development throughout adolescence. This study is a part of the Cross-National Survey on Health Behaviour in School-aged Children – World Health Organization Collaborative Study (HBSC. It aims to describe family time in joint activities and to clarify the role of social and structural family profile in a cross-national perspective. Methods The research was carried out according to the methodology of the HBSC study using the anonymous standardized questionnaire. In total, 17,761 students (8,649 boys and 9,112 girls aged 13 and 15 years from 6 European countries (Czech Republic, Finland, Greenland, Lithuania, Spain, and Ukraine were surveyed in the 2001–2002 school-year. The evaluation of joint family activity is based on 8 items: (1 watching TV or a video, (2 playing indoor games, (3 eating meals, (4 going for a walk, (5 going places, (6 visiting friends or relatives, (7 playing sports, (8 sitting and talking about things (chatting. Results Students from Spain and Ukraine reported spending the most time together with their families in almost all kinds of joint activities, whereas students from Greenland and Finland reported spending the least of this time. Boys were more likely than girls to be spending time together with family. Joint family activity goes into decline in age from 13 to 15 years. Variability of family time in a cross-national perspective was relatively small and related to children age category. Considering national, gender and age differences of studied population groups, we found that the distribution of joint family activities tends to be dispersed significantly by family structure (intact/restructured family and family wealth. Conclusion Our study compares children and parent joint activities in European countries and reveals differences and similarities in these patterns between countries. The findings

  10. Joint implementation - project simulation and organisation. Operationalization of a new instrument of climate policy

    The study served to analyze the practical aspects of 'Joint Implementation' (JI) under the Framework Convention on Climate Change, in which measures to reduce greenhouse gas emissions are carried out jointly by several countries. As a first step, possible climate protection measures were assessed with respect to their suitability for JI and an overview of suitable JI projects was compiled. In a further step, carried out in cooperation with partners from industry, four specific projects (coal-fired power plant, solar-thermal power plant, cement factory, least-cost planning) were used to simulate JI. In this work, solutions were developed for the calculation of greenhouse gas emissions avoided as well as for project reporting. In addition, proposals were made with respect to the organizational and institutional design on an international JI mechanism. (orig.)

  11. International negotiations on climate policy. Reduction targets, Joint Implementation and tradeable emission permits

    From 1 to 12 December 1997, member states of the United Nations will be negotiating targets and instruments to curb climate change. This paper outlines the background to these negotiations, providing an overview of the actors, proposals and issues. In the discussion on targets, actors will stress, among other things, problems of enforcement, fear of limits to economic growth and free-riding by developing countries. The political acceptance of ambitious reduction targets is therefore unlikely. The discussion on instruments focuses on international cooperation through Joint Implementation and tradeable emission permits. But the potential cost-effectiveness of these instruments is hampered by conceptual and practical problems. 2 tabs., 15 refs

  12. Legal aspects of Joint Pre-Commercial Procurements: from modeling to implementation

    CERN. Geneva

    2015-01-01

    The delivery of Information and Communication Technology (ICT) services is changing fundamentally. Cloud-based services are replacing traditional local - or on-premises - software and infrastructure installations for many public sector organisations. This applies to government but also to public research organisations, including libraries, which currently deal with the outburst of big data and the need for additional computing capacity. While technology service options continue to evolve, procurement processes and policies have remained firmly rooted in historical practices that are no longer effective. In order for public research organisations of all sizes to take advantage of the best solutions the market has to offer nowadays, a more flexible and agile procurement process must be created and implemented. The objective of this presentation is to review strategies and tips in order to help procurers implement and publish a Joint Pre-Commercial Procurement tender; including: General legal framework of PC...

    2016-06-01

    Full Text Available In this research work, we proposed a most effective noble approach for Human activity recognition in real-time environments. We recognize several distinct dynamic human activity actions using kinect. A 3D skeleton data is processed from real-time video gesture to sequence of frames and getter skeleton joints (Energy Joints, orientation, rotations of joint angles from selected setof frames. We are using joint angle and orientations, rotations information from Kinect therefore less computation required. However, after extracting the set of frames we implemented several classification techniques Principal Component Analysis (PCA with several distance based classifiers and Artificial Neural Network (ANN respectively with some variants for classify our all different gesture models. However, we conclude that use very less number of frame (10-15% for train our system efficiently from the entire set of gesture frames. Moreover, after successfully completion of our classification methods we clinch an excellent overall accuracy 94%, 96% and 98% respectively. We finally observe that our proposed system is more useful than comparing to other existing system, therefore our model is best suitable for real-time application such as in video games for player action/gesture recognition.

  16. Biomass energy projects for joint implementation of the UN FCCC [Framework Convention on Climate Change

    The UN Framework Convention on Climate Change (FCCC) allows for the joint implementation (JI) of measures to mitigate the emissions of greenhouse gases. The concept of JI refers to the implementation of such measures in one country with partial or full financial and/or technical support from another country, potentially fulfilling some of the supporting country's emission-reduction commitment under the FCCC. This paper addresses some key issues related to JI under the FCCC as they relate to the development of biomass energy projects for carbon offsets in developing countries. Issues include the reference case or baseline, carbon accounting and net carbon storage, potential project implementation barriers and risks, monitoring and verification, local agreements and host-country approval. All of these issues are important in project design and evaluation. We discuss briefly several case studies, which consist of a biomass-fueled co-generation projects under development at large sugar mills in the Philippines, India and Brazil, as potential JI projects. The case studies illustrate the benefits of bioenergy for reducing carbon emissions and some of the important barriers and difficulties in developing and crediting such projects. Results to date illustrate both the achievements and the difficulties of this type of project. (author)

  17. Joint Implementation under the UN Framework Convention on Climate Change. Technical and institutional challenges

    The UN Framework Convention of Climate Change (FCCC) allows for the Joint Implementation (JI) of measures to mitigate the emissions of greenhouse gases. The concept of JI refers to the implementation of such measures in one country with partial and/or technical support from another country, potentially fulfilling some of the supporting country's emission-reduction commitment under the FCCC. At present, all JI transactions are voluntary, and no country has claimed JI credit against existing FCCC commitments. Nevertheless, JI could have important implications for both the economic efficiency and the international equity of the implementation of the FCCC. The paper discusses some of the information needs of JI projects and seeks to clarify some of the common assumptions and arguments about JI. Issues regarding JI are distinguished according to those that are specific to JI as well as other types of regimes and transactions. The focus is on the position of developing countries and their potential risks and benefits regarding JI. 2 figs., 3 tabs., 35 refs

  18. Long-run implications for developing countries of joint implementation of greenhouse gas mitigation

    Joint Implementation (JI) calls for cooperation between industrialized and developing countries in the mitigation of greenhouse gas (GHG) emissions. However, a major concern of potential host countries is that if they utilize their low-cost options for JI now, they will be left with only high cost options in the future, thereby penalizing them at a time when they may be obligated to mitigate GHGs themselves. This paper formalizes this hypothesis by utilizing an optimal control framework analogous to the Hotelling model of non-renewable resource extraction. The results are that cumulative abatement effects can impose costs on the future, but that they can be offset by technological change, market power, or compensation. 11 refs

  19. Poverty and environment in Amazonia: a specific challenge for joint implementation

    Mitschein, T.A.; Schreiber, V. [Federal University of Para (Brazil). Program Poverty and Environment in Amazonia

    1998-08-01

    The largest continuous tropical forest is found in Amazonia. Its destruction by burning for cattle pastures and subsistence agriculture contributes to the increases in concentrations of CO{sub 2} in the atmosphere and at the same time exhausts the extraordinary biodiversity of this region. In this sense, global ecological problems such as the greenhouse effect and genetic erosion and the future modes of development in Amazonia represent the same side of a coin. This means that the elaboration and implementation of strategies that understand the value of joint implementation as an indispensable element to reverse the tendencies of devastation which are underway in the regional context are required. It is from this principle that the Program Poverty and Environment in Amazonia of the Federal University of Para has been working since its creation in 1992. Through this approach, encroachment on primary forest areas is avoided, while agroforestry systems restore degraded areas in a manner which mimics the natural regeneration of the forest, enriched with species which produce natural products with potential for industrial use.

    2008-07-01

    Full Text Available BackgroundTo increase levels of physical activity (PA, interventions that create or enhance access to places for PA are recommended. Establishing a joint use agreement is one way to increase access to existing PA and recreational facilities. The purpose of this article is to present a case study of In-Motion, a pilot joint use agreement project at one urban high school in Honolulu, Hawaii.ContextResidents of urban Honolulu are underserved by the amount of parkland and recreational facilities available for their use. The Honolulu County Department of Parks and Recreation sought to implement a joint use agreement to use the facilities of one urban high school for a recreational program. The high school selected for the pilot project has a student population primarily from low-income and ethnic minority backgrounds.MethodsAn assessment of the potential of 7 urban high schools to implement a joint use agreement was conducted to select the pilot site. In-Motion developed and implemented a joint use agreement. PA preferences of students, staff, and community members were assessed to guide recreational program offerings. Various recreational classes were offered free to the school community.ConsequencesSeveral barriers to implementing the joint use agreement and recreational program were encountered. However, participants were satisfied with the recreational classes they attended and said that the In-Motion program helped them to engage in more PA. Program awareness by high school students and staff was high.InterpretationIn-Motion has successfully modeled a pilot joint use agreement and provided new opportunities for PA to the high school’s students, teachers, and staff, and to community residents.

  1. Multi-Atlas Segmentation with Joint Label Fusion and Corrective Learning - An Open Source Implementation

    Hongzhi eWang

    2013-11-01

    Full Text Available Label fusion based multi-atlas segmentation has proven to be one of the most competitive techniques for medical image segmentation. This technique transfers segmentations from expert-labeled images, called atlases, to a novel image using deformable image registration. Errors produced by label transfer are further reduced by label fusion that combines the results produced by all atlases into a consensus solution. Among the proposed label fusion strategies, weighted voting with spatially varying weight distributions derived from atlas-target intensity similarity is a simple and highly effective label fusion technique. However, one limitation of most weighted voting methods is that the weights are computed independently for each atlas, without taking into account the fact that different atlases may produce similar label errors. To address this problem, we recently developed the joint label fusion technique and the corrective learning technique, which won the first place of the 2012 MICCAI Multi-Atlas Labeling Challenge and was one of the top performers in 2013 MICCAI Segmentation: Algorithms, Theory and Applications (SATA challenge. To make our techniques more accessible to the scientific research community, we describe an Insight-Toolkit based open source implementation of our label fusion methods. Our implementation extends our methods to work with multi-modality imaging data and is more suitable for segmentation problems with multiple labels. We demonstrate the usage of our tools through applying them to the 2012 MICCAI Multi-Atlas Labeling Challenge brain image dataset and the 2013 SATA challenge canine leg image dataset. We report the best results on these two datasets so far.

  4. Degenerative joint disease on MRI and physical activity: a clinical study of the knee joint in 320 patients

    We examined 320 patients with MRI and arthroscopy after an acute trauma to evaluate MRI in diagnosis of degenerative joint disease of the knee in relation to sports activity and clinical data. Lesions of cartilage and menisci on MRI were registered by two radiologists in consensus without knowledge of arthroscopy. Arthroscopy demonstrated grade-1 to grade-4 lesions of cartilage on 729 of 1920 joint surfaces of 320 knees, and MRI diagnosed 14 % of grade-1, 32 % of grade-2, 94 % of grade-3, and 100 % of grade-4 lesions. Arthroscopy explored 1280 meniscal areas and showed degenerations in 10 %, tears in 11.4 %, and complex lesions in 9.2 %. Magnetic resonance imaging was in agreement with arthroscopy in 81 % showing more degenerations but less tears of menisci than arthroscopy. Using a global system for grading the total damage of the knee joint into none, mild, moderate, or severe changes, agreement between arthroscopy and MRI was found in 82 %. Magnetic resonance imaging and arthroscopy showed coherently that degree of degenerative joint changes was significantly correlated to patient age or previous knee trauma. Patients over 40 years had moderate to severe changes on MRI in 45 % and patients under 30 years in only 22 %. Knee joints with a history of trauma without complete structural or functional reconstitution showed marked changes on MRI in 57 %, whereas stable joints without such alterations had degenerative changes in only 26 %. There was no correlation of degenerative disease to gender, weight, type, frequency, and intensity of sports activity. Therefore, MRI is an effective non-invasive imaging method for exact localization and quantification of chronic joint changes of cartilage and menisci that recommends MRI for monitoring in sports medicine.

  5. Somatomedin activity in synovial fluid from patients with joint diseases

    The somatomedin activity in synovial fluids from 50 patients with a variety of joint diseases has been studied and compared with the activity in each of the Patient's own serum and a standard reference serum (SRS). The porcine costal cartilage bioassay of Van den Brande and Du Caju (Acta Endocrinologica, 75, 233, 1974), has been used with the isotopes 3H-thymidine and 35S-sulphate. Synovial fluids from most patients with post-traumatic and post-operative effusions, osteoarthritis and arthritis associated with psoriasis, Reiter's disease, and ankylosing spondylitis stimulated the synthesis of DNA and proteoglycans in cartilage. Synovial fluids from patients with rheumatoid arthritis either had impaired capacity to stimulate DNA synthesis, or they inhibited it; a similar, but less evident pattern was observed for proteoglycan synthesis. Some synovial fluids from patients with miscellaneous synovitides stimulated, while other inhibited cartilage metabolism. It is concluded that the synovial fluid from patients with rheumatoid arthritis and from patients with miscellaneous synovitides contained an inhibitor(s) to DNA and possible proteoglycan synthesis. The sera from nearly all the patients stimulated both DNA and proteoglycan synthesis, but the somatomedin potency ratios for serum in terms of SRS were generally less than 1.0. There was a significant inverse correlation between the serum somatomedin potency ratio and the age of the patient. (author)

  6. Implementation of safeguards at the Ulba Joint Stock Company, Fuel Fabrication Plant, UST-Kamenogorsk, Kazakstan

    The Ulba Joint Stock Company Fuel Fabrication Plant (ULBA) produces VVER and RMBK fuel pellets. The facility has an annual capacity in excess of 1,000 metric tons with the pellets sold primarily to facilities in Russia for loading into rods and the production of fuel assemblies. The facility is part of a four plant complex at Ust-Kamenogorsk, Kazakstan. The Department of Energy (DOE) support for the enhancement of the facility Material Protection, Control and Accounting (MPC and A) programs started with the initial site survey in September 1994. During 1994 a two-person team for the US provided on-site assistance as part of the facility preparation for the initial physical inventory used to determine the quantities present for the declaration statement by the Republic of Kazakstan to the International Atomic Energy Agency (IAEA). The DOE support program has been funded primarily through the Nunn-Lugar Cooperative Threat Reduction Program. The management at the ULBA facility has demonstrated a commitment to developing a comprehensive Material Control and Accounting (MC and A) Program and has assigned staff and resources to the MC and A program. The facility has developed the structure and framework for the MC and A system and has developed procedures in several key MC and A areas. Initially the facility staff had a limited understanding of the purposes of a MC and A program but, through the continuing work with the DOE technical Team, there are a large number of staff throughout the facility who understand MC and A requirements and are committed to implementation of the MC and A system

  10. Implementation of ICT in Higher Education as Interacting Activity Systems

    Nyvang, Tom

    2006-01-01

    Implementation of ICT in higher education is not a trivial process. It is however a process leading to a number of challenges and problems. The paper develops a theoretical model of the implementation of ICT in higher education based on activity theory and on a case study in a Danish university....... The model suggest that implementation in itself is an activity system. The implementation activity is composed of three processes: Selection of ICT; adaptation of ICT and change of practice with ICT. Furthermore the model suggests that the implementation activity interacts with and systems development...... activity and an educational activity. Based on the model and case study the paper suggest a framework of challenges that must be met for an implementation to succeed....

  11. Etude Climat no. 33 'Joint Implementation: a frontier mechanism within the borders of an emissions cap'

    Among the publications of CDC Climat Research, 'Climate Reports' offer in-depth analyses on a given subject. This issue addresses the following points: Based on specific projects rather than economy-wide emissions reductions, and driven by the demand from the installations covered by the European Union Emissions Trading Scheme (EU ETS), Joint Implementation (JI) turned out to be a largely private sector mechanism. Besides attracting private investors in GHG abatement projects, JI creates an opportunity for countries to exploit the arbitrage price spread between different carbon offsets: Emission Reduction Units (ERU), the credits issued from JI projects, trade with a premium of up to 50% over Assigned Amount Units (AAU), the country-level carbon allowances. Some countries, like for instance Ukraine, quickly realized the added value of JI and boosted its development, while in others, like Russia, JI lacked political support and efficient frameworks took time to be established. According to the ERU supply forecasting model developed by CDC Climat Research, Annex I countries are expected to generate up to 356 million ERUs for the first Kyoto commitment period. Around 80% of these credits shall originate from Russia and Ukraine, and up to 70 million shall be generated from countries participating in the EU ETS. Within the EU, JI has been used as a 'frontier mechanism': JI projects mostly explored abatement opportunities not covered by the scheme and, as highlighted by the case of nitrous oxide emissions from the production of nitric acid, played an important role in identifying abatement technologies and providing information to extend the scope of the EU ETS. One of the most complex issues related to JI is the practice of additionality. The cases of France and Ukraine demonstrate that the stakes associated with additionality may differ depending on a country's compliance position. In Ukraine, additionality was not perceived as a significant economic risk due to a

    Research was made to promote Activities Implemented Jointly Japan Program. Joint Implementation (JI) is the methodology for preventing global climate changes by collaboration of countries. The countries take cooperative actions for reduction, absorption and fixation of greenhouse gases, and effectively distribute the reduction credits among relevant parties. This was decided in the first session of the Conference of Parties (COP) held in March, 1995. In COP3, Japan`s assigned reduction amount in 2008-2012 was determined as 6% of the emission level in 1990. The protocol defines JI between parties as dealings of emission reduction units, and JI between developing countries as clean development mechanism. The rules for a base line and credit distribution are necessary before full-scale implementation. Although JI is regarded as an important cost-effective project, it is important to decide where and how the JI projects should been promoted. The present state and issues of the primary approved project of Japan Program are arranged. In particular, various terms related to developing countries remain to be solved. 21 figs., 32 tabs.

    2004-01-01

    Business game can be used not only as an educational tool for the development of decision making ability, but also can be used for supporting the knowledge creation activity in organizations. In this paper, some conceptual considerations to meanings of the business game in the knowledge creation activity by using the knowledge creation theory and other related theories are given,and business game activity concept which refers to game play and development is proposed. Then focusing on the business game activity as an instantiation of the knowledge creation activity, and a Web based gaming activity support system based on the former system called YBG that enables us to play and develop many business games through the standard web browser is proposed. This system also provides us a lot of opportunities to play and develop the business games over business game communities.

    To many observers, the current recession provides compelling circumstances for renewed fiscal policy activism. But the strong support for fiscal policy intervention reflects a renewed belief in policy activism that had already appeared before the present crisis. However, the recent debate about possible fiscal policy interventions suggests that we are still relying on the approaches to discretionary policy used in past periods of policy activism. It is not surprising that there have been few ...

  18. Dynamic structure of joint-action stimulus-response activity.

    MaryLauren Malone

    Full Text Available The mere presence of a co-actor can influence an individual's response behavior. For instance, a social Simon effect has been observed when two individuals perform a Go/No-Go response to one of two stimuli in the presence of each other, but not when they perform the same task alone. Such effects are argued to provide evidence that individuals co-represent the task goals and the to-be-performed actions of a co-actor. Motivated by the complex-systems approach, the present study was designed to investigate an alternative hypothesis--that such joint-action effects are due to a dynamical (time-evolving interpersonal coupling that operates to perturb the behavior of socially situated actors. To investigate this possibility, participants performed a standard Go/No-Go Simon task in joint and individual conditions. The dynamic structure of recorded reaction times was examined using fractal statistics and instantaneous cross-correlation. Consistent with our hypothesis that participants responding in a shared space would become behaviorally coupled, the analyses revealed that reaction times in the joint condition displayed decreased fractal structure (indicative of interpersonal perturbation processes modulating ongoing participant behavior compared to the individual condition, and were more correlated across a range of time-scales compared to the reaction times of pseudo-pair controls. Collectively, the findings imply that dynamic processes might underlie social stimulus-response compatibility effects and shape joint cognitive processes in general.

    Micro slurry-jet erosion has been proposed as a precision machining technique for the bearing surfaces of artificial joints in order to reduce the total amount of polyethylene wear and to enlarge the size of the wear debris. The micro slurry-jet erosion method is a wet blasting technique which uses alumina particles as the abrasive medium along with compressed air and water to create an ideal surface. Pin-on-disc wear tests with multidirectional sliding motion on the textured surface of a \\text{Co}-\\text{Cr}-\\text{Mo} alloy counterface for polyethylene resulted in both a reduction of wear as well as enlargement of the polyethylene debris size. In this study, primary human peripheral blood mononuclear phagocytes were incubated with the debris, and it was elucidated that the wear debris generated on the textured surface regulated secretion of the proinflammatory cytokines IL-6 and TNF-α, indicating a reduction in the induced tissue reaction and joint loosening.

    Research was made on joint implementation (JI) for preventing global climate changes in China. Since such the stove and furnace consume a large amount of energy, their improvement and energy saving are important for integrated iron plants. Maanshan iron plant was selected for the research. All the furnaces were manually operated without combustion control systems, and oxygen meters for exhaust gas frequently troubled. As measures for the stoves, operation at a proper air fuel ratio, improvement of over heat storage combustion, and dust cleaning for waste heat recovery gas heaters were proposed. For the furnaces, a proper oxygen content at the end of furnaces (reduction of invasion air) was proposed to improve exhaust gas loss up to that in Japan. For this target, reinforced instrument management and standardized combustion control are essential. JI of software improvement for operation and management can reduce annual greenhouse effect gas emission to 45,900t and 6,300t in carbon equivalent for the stove and furnace, respectively. CO2 reduction is also estimated to be 1,173,000t and 205,000t in China of 107,570,000t in raw steel production, respectively. 28 figs., 32 tabs.

    In an effort to achieve the objectives, the following provisions were made. First of all, the current status of energy industry was carefully reviewed. An increase of energy consumption, both in industrial and home purposes, implored introduction of nuclear power as an alternative energy production source. Secondly, the current status of China's nuclear development programs together with future prospects was reviewed. Through this review, more effective implementation of nuclear cooperative programs could be devised. Thirdly, China's newly developed nuclear infrastructure was analyzed. The re-structuring of the CNNC was reviewed. Based on this analysis, future cooperative programs could be identified. Lastly, proper strategies for future cooperation between the two countries on a complementary basis were studied. Recommendations for better cooperation programs, particularly for the nuclear policy-making process, were presented. For fruitful cooperation, it is naturally needed match funds to support the implementation of joint projects. It is basically China's idea that Korea provides the funds and China provides manpower. China has a great potential market. The Korean Governments support for key funds for cooperative programs will thus have a sincere meaning.

    2011-09-01

    Full Text Available Many everyday life situations require two or more individuals to execute actions together. Assessing brain activation during naturalistic tasks to uncover relevant processes underlying such real-life joint action situations has remained a methodological challenge. In the present study, we introduce a novel joint action paradigm that enables the assessment of brain activation during real-life joint action tasks using functional near-infrared spectroscopy (fNIRS. We monitored brain activation of participants who coordinated complex actions with a partner sitting opposite them. Participants performed table-setting tasks, either alone (solo action or in cooperation with a partner (joint action, or they observed the partner performing the task (action observation. Comparing joint action and solo action revealed stronger activation (higher [oxy-Hb]-concentration during joint action in a number of areas. Among these were areas in the inferior parietal lobule (IPL that additionally showed an overlap of activation during action observation and solo action. Areas with such a close link between action observation and action execution have been associated with action simulation processes. The magnitude of activation in these IPL areas also varied according to joint action type and its respective demand on action simulation. The results validate fNIRS as an imaging technique for exploring the functional correlates of interindividual action coordination in real-life settings and suggest that coordinating actions in real-life situations requires simulating the actions of the partner.

  8. Summary report of joint research in Japan on BA DEMO R and D activity 2008 (Joint research)

    R and D on DEMO engineering was started from 2007 as the main activity of a DEMO design and R and D coordination center activity which was one of the international nuclear fusion energy research center (IFERC) activity of 'Broader Approach' (BA) activity. In the DEMO engineering R and D activity, five 'generic' R and D items were selected, which attract both Japan and EU interest and not specific to a DEMO design, i.e., 1) R and D on SiC/SiC Composites: 2) R and D on Tritium Technology: 3) R and D on Materials Engineering for DEMO Blanket: (R and D on reduced activation ferritic/martensitic steel: RAFM) 4) R and D on Advanced Neutron Multiplier for DEMO Blanket: 5) R and D on Advanced Tritium Breeders for DEMO Blanket. In first phase (2007 - 2009), some part of preliminary R and D, which was defined in procurement arrangement (PA) between Japan and EU, is conducted by JAEA university collaboration. This report summarized the results from joint research activities about R and D on SiC/SiC composite and RAFM in 2008. (author)

    The aim of the study was to investigate if push-rim kinetics could be used as markers of glenohumeral joint demand during manual wheelchair accessibility activities; demonstrating a method of biomechanical analysis that could be used away from the laboratory. Propulsion forces, trunk and upper limb kinematics and surface electromyography were recorded during four propulsion tasks (level, 2.5% cross slope, 6.5% incline and 12% incline). Kinetic and kinematic data were applied to an OpenSim musculoskeletal model of the trunk and upper limb, to enable calculation of glenohumeral joint contact force. Results demonstrated a positive correlation between propulsion forces and glenohumeral joint contact forces. Both propulsion forces and joint contact forces increased as the task became more challenging. Participants demonstrated increases in trunk flexion angle as the requirement for force application increased, significantly so in the 12% incline. There were significant increases in both resultant glenohumeral joint contact forces and peak and mean normalized muscle activity levels during the incline tasks. This study demonstrated the high demand placed on the glenohumeral joint during accessibility tasks, especially as the gradient of incline increases. A lightweight instrumented wheelchair wheel has potential to guide the user to minimize upper limb demand during daily activity. PMID:26736796

  10. Novel implementation of nonlinear joint transform correlators in optical security and validation

    Weber, David C.; Trolinger, James D.

    1999-01-01

    Emblems using holograms or other diffractive devices have long been used to mark cards and other objects as a means of authentication. The effectiveness of such emblems as security devices is ultimately determined by the inspection system. Due to the expense and highly variable performance of the human inspector, automated machine reading devices are an attractive alternative for performing the verification task. An additional advantage of the machine reactor is that information regarding the card or its holder can be stored covertly. A security verification system is presented consisting of a holographic security emblem in which information is covertly stored and an automated reader based on a joint transform correlator. A holographic encoding method is used to produce an emblem that stores the required phase and/or amplitude information in the form of a complex, 3D diffraction pattern that can be interpreted only through the use of a second `key' hologram. The reader incorporates the use of the nonlinear material, bacteriorhodopsin, as a means of miniaturizing the system, reducing system cost, and improving system performance. Experimental results are presented that demonstrate the feasibility of the approach for security applications.

    This study focused on Joint Base Lewis McChord (JBLM), which is located in Washington State. Task 1 consisted of a survey of the non-tactical fleet of vehicles at JBLM to begin the review of vehicle mission assignments and the types of vehicles in service. In Task 2, daily operational characteristics of select vehicles were identified and vehicle movements were recorded in data loggers in order to characterize the vehicles’ missions. In Task 3, the results of the data analysis and observations were provided. Individual observations of the selected vehicles provided the basis for recommendations related to PEV adoption (i.e., whether a battery electric vehicle or plug-in hybrid electric vehicle [collectively referred to as PEVs] can fulfill the mission requirements0, as well as the basis for recommendations related to placement of PEV charging infrastructure. This report focuses on an implementation plan for the near-term adoption of PEVs into the JBLM fleet.

    According to the forecasts of the Central Statistical Office of Poland, in 2030 people at the age of 65 and older will account for 23.8%, i.e. their number will amount to approx. 8.5 m people. Geriatric rheumatic patients more often decide to undergo surgical joint replacement. According to the National Health Fund, the number of joint replacement services provided in 2014 increased by 93%, as compared to 2005. Improving the physical performance of this constantly expanding group of patients requires taking into account many factors to raise their functional status, reduce the risk of falling, teach rules of proper functioning with an artificial joint and encourage unassisted physical activity. Restoring fitness and independence is a difficult but necessary task due to an increasing number of seniors with replaced joint. PMID:27504021

    2016-06-01

    Creep deformation and rupture behavior of single-pass and dual-pass 316LN stainless steel (SS) weld joints fabricated by an autogenous activated tungsten inert gas welding process have been assessed by performing metallography, hardness, and conventional and impression creep tests. The fusion zone of the single-pass joint consisted of columnar zones adjacent to base metals with a central equiaxed zone, which have been modified extensively by the thermal cycle of the second pass in the dual-pass joint. The equiaxed zone in the single-pass joint, as well as in the second pass of the dual-pass joint, displayed the lowest hardness in the joints. In the dual-pass joint, the equiaxed zone of the first pass had hardness comparable to the columnar zone. The hardness variations in the joints influenced the creep deformation. The equiaxed and columnar zone in the first pass of the dual-pass joint was more creep resistant than that of the second pass. Both joints possessed lower creep rupture life than the base metal. However, the creep rupture life of the dual-pass joint was about twofolds more than that of the single-pass joint. Creep failure in the single-pass joint occurred in the central equiaxed fusion zone, whereas creep cavitation that originated in the second pass was blocked at the weld pass interface. The additional interface and strength variation between two passes in the dual-pass joint provides more restraint to creep deformation and crack propagation in the fusion zone, resulting in an increase in the creep rupture life of the dual-pass joint over the single-pass joint. Furthermore, the differences in content, morphology, and distribution of delta ferrite in the fusion zone of the joints favors more creep cavitation resistance in the dual-pass joint over the single-pass joint with the enhancement of creep rupture life.

  18. Implementation of a Quality Management System in regulatory inspection activities

    The Institute for Radioprotection and Dosimetry - IRD -, of the Brazilian National Nuclear Energy Commission, CNEN, started in 2001, the implementation of a quality management system (SGQ), in the inspection, testing and calibration activities. The SGQ was an institutional guideline and is inserted in a larger system of management of the IRD started in 1999, with the adoption of the National Quality Award criteria - PNQ, within the Project for Excellence in Technological Research of Associacao Brasileira das Instituicoes de Pesquisas Tecnologicas - ABIPTI (Brazilian Association of Technological Research institutions). The proposed quality management system and adopted at the IRD was developed and implemented in accordance with the requirements of NBR ISO/IEC 17025 - General requirements for the competence of testing and calibration laboratories, and ISO/IEC 17020 - General criteria for operation of various types of bodies performing inspections. For regulatory inspection activities, the quality system was implemented on three program inspection services of radiological protection led, respectively, by clinics and hospitals that operate radiotherapy services; industries that use nuclear gauges in their control or productive processes and power reactor operators (CNAAA) - just the environmental part. It was formed a pioneering team of inspectors for standardizing the processes, procedures and starting the implementation of the system in the areas. This work describes the implementation process steps, including difficulties, learning and advantages of the adoption of a quality management system in inspection activities

    Full Text Available Severity of hands and feet joint destruction is the most objective marker of rheumatoid arthritis (RA progression determining functional disability. The main aim of RA treatment is suppression of joint destruction. Objective. To study dependence of joint erosions forming speed on disease modifying anti-rhcumatic drugs (DMARD administration and RA activity. Material and methods. Retrospective analysis of 451 cases of RA treatment was performed. Erosions were counted according to modified Sharp method. Erosions forming speed was counted as ratio of erosion number increase to a year’s time space. Averaged disease activity was calculated as arithmetic mean for all DAS28 values obtained during disease course. Considering close relationship between disease activity and DMARD administration two-factor analysis was used. DMARD administration (>3 months and mean activity of RA were considered as factors. Results. Variance analysis (ANOVA with covariant showed that mean RA activity is a significant factor influencing erosions forming speed (F=12,5; p=4xl0 4. Character of DMARD, fact of its administration and disease duration did not significantly influence erosions forming speed considering disease activity covariant. Regression model with inclusion disease duration factor mean disease activity and DMARD administration at the moment of assessment allowed to explain 42% of dispersion (determination coefficient. Conclusion. Activity of RA is the main factor influencing erosions forming speed. Therapy not decreasing activity of RA does not change erosions forming speed

  1. Sweden's third national report under the Joint Convention on the safety of spent fuel management and on the safety of radioactive waste management. Swedish implementation of the obligations of the Joint Convention

    define their own solutions, and demonstrate the safety level achieved to the regulatory bodies. The legislation clearly defines that all licence holders are responsible for the safe handling and disposal of spent fuel and radioactive waste, as well as for the decommissioning and dismantling of facilities. The operators of nuclear power plants must jointly carry out the research and development activities needed to ensure the safe handling and disposal of spent fuel and radioactive waste, as well as for the decommissioning of facilities. The RandD programme is presented to the Government regularly and is subject to regulatory review. The licensee of a nuclear facility which generate or has generated residual products must pay a fee to the Nuclear Waste Fund, which is subject to regulatory supervision, to ensure that resources are available for the handling and disposal of spent fuel and radioactive waste, and for the decommissioning and dismantling of the facilities. The legislation provides for public insight into the activities of the licensees and also provides an opportunity for stakeholders to receive financial support to participate in the ongoing consultations process to site a repository for spent nuclear fuel. The regulatory bodies have maintained and increased their resources and are further developing their regulatory practices. There is an open and generally constructive relationship between the regulatory bodies and the licence holders. Sweden also wishes to mention that there are areas in which improvements to the national waste management system are needed: The merger of SKI and SSI will pose challenges with regard to integrating the organisations and the regulatory practices. The resources of the regulatory body need to be strengthened in order to cope with the expected work load during the coming years. The implementation of the changes to the financing system as well as the regulatory review procedures related to the financing system need to be improved

    Thorhauge, Mikkel; Vuk, Goran; Kaplan, Sigal

    2012-01-01

    The traditional approach for modeling transport-related choices in Denmark refers to individual decision makers. However, in daily activities and travel choices individuals function according to the commitments as family members, and thus their choices derive from the welfare needs of other family...... members. A family-based approach enables to capture intra-household interactions and the priorities of household members in scheduling their daily activities, thus adding to the realism and the predictive strength of transport models. Joint activities and travel occur in order to maximize efficiency and...... family quality time, within a daily schedule. The current study unveils the joint activity and travel patterns of household members in the Copenhagen area, as part of the ACTUM research project, funded by the Danish Strategic Research Council, for the development of a new generation of activity...

  7. Implementation of skeletal muscle model with advanced activation control

    Kocková H.

    2009-12-01

    Full Text Available The paper summarizes main principles of an advanced skeletal muscle model. The proposed mathematical model is suitable for a 3D muscle representation. It respects the microstructure of the muscle which is represented by three basic components: active fibers, passive fibers and a matrix. For purposes of presented work the existing material models suitable for the matrix and passive fibers are used and a new active fiber model is proposed. The active fiber model is based on the sliding cross-bridge theory of contraction. This theory is often used in modeling of skeletal and cardiac muscle contractions. In this work, a certain simplification of the cross-bridge distribution function is proposed, so that the 3D computer implementation becomes feasible. The new active fiber model is implemented into our research finite element code. A simple 3D muscle bundle-like model is created and the implemented composite model (involving the matrix, passive and active fibers is used to perform the isometric, concentric and excentric muscle contraction simulations.

  8. Joint implementation as a cost-effective climate policy measure: a Chinese perspective

    By analysing the macroeconomic and sectoral effects of carbon emission limits for China through a time-recursive dynamic computable general equilibrium model of the Chinese economy, the report shows that the carbon taxes required in China are much lower than those for both the industrialised countries and the world average in order to achieve the same percentage of emission reductions relative to the baseline. This provides the economic rationale for the development of JI projects with China. The report discusses in some detail potential areas for JI projects with China. Areas of most interest are related to those activities and options aimed at: (1) improving the efficiency of energy use, particularly at energy intensive energy sectors (e.g. iron and steel industry, chemical industry, building materials industry, and power industry) and devices (e.g. industrial boilers); (2) pushing efficient use of coal through increasing proportion of raw coal washed; popularizing domestic use of coal briquette; substitution of direct burning of coal by electricity through development of large-size, high-temperature and high-pressure efficient coal-fired power plants; expanding district heating systems and developing cogeneration; increased penetration of town gas into urban households; and through development of environmentally sound coal technologies; (3) speeding up the development of hydropower and nuclear power; and (4) developing renewables. The report addresses some operational aspects of JI from a Chinese perspective. Some JI projects are under discussion but the Chinese government has not yet approved any

  9. Epidemiological characterization of implementation of the joint scientific Ukraine-USA thyroid project

    2003) 12419 persons have been screened (93.8% of the previous screening); during the third cycle of screening (from May 2003 to November 2005) 11715 subjects (94.3% of the previous screening or 88.5% of the first cycle of screening) have had screening examinations. About 70.0% of participants were examined (120-150 persons weekly) by mobile teams at their permanent place of residence, 30.0% of study subjects (mainly those from the non-controlled areas and areas located in the neighborhood of Kyiv) were examined by the fixed team at the Institute of Endocrinology and Metabolism of the Ukraine. By the end of November 2005 590 persons (4.4% of those having undergone regular screening) have had a follow up examination according to the results of the first screening, 598 (4.8%) according to the results of the second screening, and 641 subjects (5.5%) according to the results of the third screening. Aspiration biopsy of the thyroid was performed to 755 persons (5.7% of all Project participants), including 31.2% of cases where biopsy was performed two times or more for objective reasons. 144 persons were hospitalized at the Clinic of the Institute of Endocrinology and Metabolism of the Ukraine for medical treatment, out of which 128 were operated on. The main advantages of the Ukraine-USA Thyroid Project are as follows: a) large size of sample (over 13000 screened subjects); b) availability of thyroid radioactivity measurements made shortly after the Chornobyl accident; c) possibility of individual exposure dose estimates taking account of the modifiers of the effect; d) wide range of thyroid exposure doses (from minimum to maximum ones); e) minimal impact of subjective factors' on results; f) high degree of reliability of thyroid pathology diagnosis reviewed by an international expert group of specialists. Thus, effective implementation of the Ukraine-USA Thyroid Project allows to solve important medical and social problems of the Chornobyl accident, in particular, to

    The process of territorial ordering in Peru has little experiences; one of them is the one that comes carrying out in the department from san martin, with the conduction of its respective regional government. This department is in the Amazonian natural region and comes being affected by a series from problems social (like the existent of an uncontrolled migration, deficiency of basic services), economic (unemployment, un mannerliness), legal (territorial invasions to the property, conflicts) and environmental (deforestation, gradual loss of the biodiversity, environmental contamination), in addition to the loss of leadership of the organizations responsible for the departmental development. As opposed to it, the local institutional organizations decided to give priority as of year 2004 to the project of territorial ordering as a measurement to obtain the use and suitable occupation of the territory. This project has between its characteristics the one to gather and to group the experiences in demarcation and territorial organization, economic ecological zincification, road management of the use of the territory, plans and conformation of regions.

  12. Implementation of cystic fibrosis services in developing countries: memorandum from a Joint WHO/ICF(M)A meeting.

    1997-01-01

    A Joint WHO/ICF(M)A meeting defined strategies for the implementation and development of cystic fibrosis (CF) services in countries where CF is thought to be more common than is appreciated by the medical profession or the public and where CF services are either non-existent or in the early stages of development. The following common problems in such countries were identified: underdiagnosis; reduced life expectancy (relative to developed countries) among those diagnosed; a clinical profile that may vary from the "classic" description; poor availability of necessary drugs; and a lack of CF services or basic research on the condition. The following recommendations were made concerning CF: neonatal screening projects should be set up to determine its incidence and identify affected infants; national and regional laboratories should be encouraged to identify the specific mutations responsible for the condition in their populations; centres for diagnosis and treatment should be developed, using a team approach; a national organization, involving families and friends of individuals with CF and other volunteers, should be established; a national registry should be set up; awareness about the condition should be improved and knowledge about it developed among medical professionals, public health authorities, and the general public; and increased collaboration between groups and organizations (including pharmaceutical companies) at the national, regional, and international levels should be developed in order to exchange information about and promote knowledge of CF, and to stimulate the development of CF services in developing countries.

  13. Methods for dynamic characterization of the major muscles activating the lower limb joints in cycling motion

    Navit Roth

    2014-04-01

    Full Text Available The functional activation, through electrical stimulation, of the lower limb consisting of several deficient muscles requires well-patterned and coordinated activation of these muscles. This study presents a method for characterizing the parameters of the major muscle groups controlling the ankle and knee joints in cycling motion, the latter having particular significance in the rehabilitation of locomotion. To lower mechanical indeterminacy in the joints the system is reduced by grouping the muscles acting in synergism. The joint torques were calculated by inverse dynamics methods from cycling motion data, including kinematics and foot/pedal reaction loads (forces, moments. The mechanical indeterminacy was resolved by applying optimization criteria and the individual muscle torques were parceled-out from the joint torques. System identification of the individual muscles, part of which being bi-articular, in this non-isometric condition was performed from the relationship between the evaluated force and the measured EMG of each the muscles, using both first and second order linear transfer functions. Feasibility of the presented method was demonstrated through the computation of the coefficients of the muscles involved and validating the results on the experimental data obtained from one subject.

  17. Sweden's second national report under the Joint Convention on the safety of spent fuel management and on the safety of radioactive waste management. Swedish implementation of the obligations of the Joint Convention

    Article 32 of the Joint Convention calls for a self-assessment by each Contracting Party regarding compliance with the obligations of the Convention. Sweden's self-assessment has demonstrated compliance with all the obligations of the Convention, as shown in detail in sections B to K of this report. Having taken a very active part in the creation of the Joint Convention, Sweden wishes to emphasise the incentive character of the Convention. In Sweden's opinion, the Convention implies a commitment to continuous improvement of safety whenever operating experience, safety research or technical development indicates that there is room for such improvement. Continuous learning from experience and a proactive approach to safety are in fact corner stones of the current Swedish nuclear and radiation safety work, both for the industry and the regulatory bodies. Therefore, Sweden has found it important that its National Report highlights strong features in national practices, as well as areas in which improvements are justified. Implementation of such improvements should then be followed up in the National Reports to subsequent Review Meetings. The major events in the Swedish nuclear programme since the first report to the Convention was issued are: - The general safety regulations of SKI have been revised and issued as SKIFS 2004:1. - A commission of inquiry has been carried out in order to review and suggest improvements to the financing system. - The second unit of the twin nuclear power plant unit at Barsebaeck (Barsebaeck 2) was permanently shut down 31 May 2005. The first unit (Barsebaeck 1) was closed in 1999. - The research reactors R2 and R2-0 at the Studsvik site were permanently shut down 16 June 2005. - The Swedish Nuclear Fuel and Waste Management Co. (SKB) has announced its decision to take over operation of the interim storage facility for spent nuclear fuel (Clab). The operation of Clab is currently contracted out to OKG, who operates the three nuclear power

  18. Implementation Practices of Finland in Facilitating IAEA Verification Activities

    The Member States provide the information to the IAEA according to the Safeguards Agreements and Additional Protocols. For example, the requirements to provide the reports and declarations are very general and there are no explanation what the IAEA is looking for from that information. It is important for the States to understand how their efforts to collect and provide information, and to facilitate IAEA verification activities, contribute to the achievement of objectives and finally to draw conclusions on the exclusively peaceful use of nuclear materials in a State. The IAEA is producing a new series of guidance called Safeguards Implementation Practices, SIP, guides, which are shedding light on the requirements and sharing the good practices of States. It is hoped that the SIP Guides will create a better understanding of the needs of the IAEA and the important role of States and facility operators in achieving safeguards objectives. The guides are also important for the States to share their lessons learned and good practices for the benefit of other States that might be developing their capabilities or enhancing their processes and procedures. The way is very wide and long, when a State decides to start up a new nuclear programme. At first there is a need for legislation, regulatory body, contact point, international agreements and then finally practical implementation of the safeguards in the nuclear facilities. There are a lot of issues to be prepared in advance to facilitate the IAEA's implementation of verification activities successfully, effectively and with the good quality. Using the structure of the IAEA's draft SIP Guide on Facilitating Verification Activities as a framework, this paper will describe the most relevant implementation practices and experiences in Finland.

  3. Joint retrieval of surface reflectance and aerosol optical depth from MSG/SEVIRI observations with an optimal estimation approach: 2. Implementation and evaluation

    Wagner, S. C.; Govaerts, Y. M.; Lattanzio, A.

    2010-01-01

    An original method, based on optimal estimation, was presented in a part one of this paper for the joint retrieval of the mean daily total column aerosol optical depth and the surface Bidirectional Reflectance Factor (BRF) from the daily accumulated Meteosat Second Generation-Spinning Enhanced Visible and Infrared Imager (MSG/SEVIRI) observations in the solar channels. The objective of this paper is to evaluate the benefits of the proposed approach and to document the limits of the algorithm assumptions in the context of its implementation in an operational ground segment. A twofold approach is followed. In a first step, by looking at the posterior correlation error matrix the capability of the so-called Land Daily Aerosol (LDA) algorithm to decouple the surface-atmosphere signal is analyzed. In particular, the impact of the prior information is investigated in detail. In a second step, the results of the algorithm are compared with independent data sets of aerosol optical depth and surface reflectance. In this phase, the accuracy of the algorithm is evaluated against ground observations from the AERONET network. LDA is shown to be in good agreement with these data, especially when the prior update mechanism is activated. Comparisons with the MODIS surface product showed that the bihemispherical reflectance derived from the LDA products is consistent with the equivalent MODIS white-sky albedo. Aerosol spatial distributions are comparable in terms of geographical location and intensity, in particular for aerosol episodes with a limited daily variation.

    Behringer, Bruce; Mabe, Karen Harrell; Dorgan, Kelly A; Hutson, Sadie P

    2009-01-01

    Underserved communities with high cancer rates often are not involved in implementing state cancer control activities locally. An East Tennessee State University research team formed 2 Appalachian Community Cancer Research Review Work Groups, 1 in northeast Tennessee and 1 in southwest Virginia. During 4 sessions, the research team presented regional cancer data to the work groups. Work group participants explored research from a lay perspective and identified possible reasons for cancer disparities in central Appalachia. The fifth session was a community dissemination activity in which work group participants engaged in cancer education and action by presenting the research to their local communities in unique ways. During a sixth session, both work groups discussed these interventions and further attempted to answer the question, "What makes the experience of cancer unique in Appalachia?" This article describes the key steps of this community-based participatory research process. PMID:19080040

  7. Statistical measurements of library activities: implementation of ISO 2789 : 2003

    Eva Kodrič-Dačič

    2004-01-01

    Full Text Available The author presents statistical measurements of library activities in Slovenia and some problems which emerge when implementing the novelties of the new edition of ISO 2789 : 2003 from the standpoint of a librarian, who provides statistics on the national level. Collecting library statistics already has a long tradition in Slovenia and is presently carried out by the Statistical Office of the Republic of Slovenia and by the National Centre for Library Development at the National and University Library, which is also responsible for the content of statistical questionnaires. The questionnaires are based on UNESCO statistical questionnaires and ISO standards while in the last decade there have been some changes due to the requirements of the LIBECON project. As a response to the needs of the information society, libraries develop new services which have to be measured and monitored. The third edition of the standard ISO 2789 : 2003 has defined new measures which are needed to perform statistical research of library activities in the digital environment. In order to preserve international comparability of statistical data it is necessary to implement the novelties of the ISO standard in the national statistics. However, there are at least three problems: how to preserve comparability of the data with previous statistics, how to collect them and how to educate librarians to report the relevant data.

    2016-02-01

    We tested the in vitro activity of ceftaroline by Etest against staphylococci recovered from patients with prosthetic joint infection, including 97 Staphylococcus aureus isolates (36%, oxacillin resistant) and 74 Staphylococcus epidermidis isolates (74%, oxacillin resistant). Ceftaroline inhibited all staphylococci at ≤0.5 μg/mL. The ceftaroline MIC(90/50) values for methicillin-susceptible S. aureus, methicillin-susceptible S. epidermidis, methicillin-resistant S. aureus, and methicillin-resistant S. epidermidis were 0.19/0.125, 0.094/0.047, 0.5/0.38, and 0.38/0.19 μg/mL, respectively. Based on these in vitro findings, ceftaroline should be further evaluated as a potential therapeutic option for the treatment of prosthetic joint infection caused by methicillin-susceptible and methicillin-resistant S. aureus and S. epidermidis.

  10. Sports activity after total joint arthroplasty: recommendations for the counseling physician.

    Buza, John A; Fink, Leslie A; Levine, William N

    2013-02-01

    Sports activity after total joint arthroplasty (TJA) has become an increasingly important topic, as many younger patients seeking TJA have higher postoperative expectations with regard to return to athletic activity. Our current knowledge of this area is largely based on retrospective clinical studies and surveys of surgeon recommendations. The decision to participate in sports after TJA depends on the patient's general health, prior athletic experience, type of TJA, and desired sporting activity. Ultimately, patients should discuss these factors with their physician in order to make an educated decision regarding sports activity after TJA. This article summarizes the best available evidence to help guide physicians in their conversation with patients regarding safe and appropriate sports activity after TJA. PMID:23445855

  11. Could a geological storage of the CO2 emissions from Romanian power plants become a joint implementation project?

    Full text: Emissions trading is a solution that is most compatible with deregulated electricity markets. The Directive 2003/87/CE referring to CO2 emission trading within Europe entered into force and till 31 March 2004 all the countries had to present to the Commission their national plan to comply with Directive's rules. Recent predictions of the Intergovernmental Panel on Climate Change indicate that global warming will accelerate within this century. CO2 emitted by the burning of fossil fuels is thought to be a main driving factor of climate change. With the potential to produce power without releasing CO2 into the atmosphere, CO2 capturing may become an important part of the post- Kyoto strategies of many countries. Underground storage of CO2 seems to be one of the most attractive alternative. Potential targets for CO2 injection are: - depleted oil reservoirs, possibly in combination with enhanced oil recovery - former gas fields, possibly with additional gas production - deep aquifers containing saline, non-drinkable water - deep and unminable coal seams (exchange of absorbed methane by CO2 with simultaneous gas production) - geothermal wells, after heat extraction from the aquifers - residual volumes of former deep coal and salt mines. An environmental political decision about the option of CO2 underground storage has to consider forecasts about developments of global climate, societies, and economics. Due to the forthcoming emission trading there is a growing interest in underground storage options for CO2 in Europe now. Flexible mechanisms agreed by Kyoto Protocol, namely the Project-based Joint Implementation (Art. 6) and the Emission Trading (Art. 17) could help Romania to attract investment with a long term impact on emissions reduction. The brief identification of major CO2 emissions sources and of possible CO2 geological storage capacities (coal mines, aquifers, geothermal wells, oil and gas fields) shows that it is very probable to identify technical

  12. In-vitro and in-vivo imaging of MMP activity in cartilage and joint injury

    Non-destructive detection of cartilage-degrading activities represents an advance in osteoarthritis (OA) research, with implications in studies of OA pathogenesis, progression, and intervention strategies. Matrix metalloproteinases (MMPs) are principal cartilage degrading enzymes that contribute to OA pathogenesis. MMPSense750 is an in-vivo fluorimetric imaging probe with the potential to continuously and non-invasively trace real-time MMP activities, but its use in OA-related research has not been reported. Our objective is to detect and characterize the early degradation activities shortly after cartilage or joint injury with MMPSense750. We determined the appropriate concentration, assay time, and linear range using various concentrations of recombinant MMPs as standards. We then quantified MMP activity from cartilage explants subjected to either mechanical injury or inflammatory cytokine treatment in-vitro. Finally, we performed in-vivo MMP imaging of a mouse model of post-traumatic OA. Our in-vitro results showed that the optimal assay time was highly dependent on the MMP enzyme. In cartilage explant culture media, mechanical impact or cytokine treatment increased MMP activity. Injured knees of mice showed significantly higher fluorescent signal than uninjured knees. We conclude that MMPSense750 detects human MMP activities and can be used for in-vitro study with cartilage, as well as in-vivo studies of knee injury, and can offering real-time insight into the degradative processes that occurring within the joint before structural changes become evident radiographically. - Highlights: • MMPSense750 is near-infrared fluorescent probe which can detect MMP activity. • MMPSense750 can detect human MMP-3, -9, and -13. • The reaction kinetics with MMPSense750 were different for the three MMPs. • MMPSense750 can visualized real time MMP activity in mouse injured knees. • MMPSense750 is convenient tool to evaluate real-time MMP activity non-invasively

  14. Structural health monitoring of multi-spot welded joints using a lead zirconate titanate based active sensing approach

    Yao, Ping; Kong, Qingzhao; Xu, Kai; Jiang, Tianyong; Huo, Lin-sheng; Song, Gangbing

    2016-01-01

    Failures of spot welded joints directly reduce the load capacity of adjacent structures. Due to their complexity and invisibility, real-time health monitoring of spot welded joints is still a challenge. In this paper, a lead zirconate titanate (PZT) based active sensing approach was proposed to monitor the structural health of multi-spot welded joints in real time. In the active sensing approach, one PZT transducer was used as an actuator to generate a guided stress wave, while another one, as a sensor, detected the wave response. Failure of a spot welded joint reduces the stress wave paths and attenuates the wave propagation energy from the actuator to the sensor. A total of four specimens made of dual phase steel with spot welds, including two specimens with 20 mm intervals of spot welded joints and two with 25 mm intervals, were designed and fabricated for this research. Under tensile tests, the spot welded joints successively failed, resulting in the PZT sensor reporting decreased received energy. The energy attenuations due to the failures of joints were clearly observed by the PZT sensor signal in both the time domain and frequency domain. In addition, a wavelet packet-based spot-weld failure indicator was developed to quantitatively evaluate the failure condition corresponding to the number of failed joints.

  15. The IEA/bioenergy implementing agreement and other activities

    Costello, R. [U.S. Department of Energy, Washington D.C. (United States). Biofuels Systems Div.

    1996-12-31

    Implementing Agreements (IAs) are used widely in international collaborative work within the International Energy Agency (IEA). These agreements are meant to be very flexible depending on the nature of the work and the interests of the participating countries. Many IAs are directed at the development of specific technologies, while a number of IAs are primarily used to facilitate information collection and dissemination. There are also a number of agreements that do not deal directly with technology development, but deal with environmental, economic and safety aspects of the technologies under development. The IEA Bioenergy Agreement is a prime example of how Implementing Agreements can be utilised to establish and expand cooperative research for the effective leveraging of technical knowledge and financial resources in finding solutions to the future needs of a growing energy dependent world. As will be illustrated, these activities are important to the commercialisation and deployment of bioenergy technologies, which increasingly are being visualized as one of the few options that can maintain and promote economic and environmental stability

  18. Introduction to decommissioning activities implemented by EWN in Germany

    Germany stands among the front runners in the field old decommissioning of commercial nuclear power plants, from the standpoints of length of experience and scale of work. In Germany, EWN is now working on the decommissioning of six nuclear reactors. This is the largest decommissioning activity being performed in the world. JGC concluded a collaboration agreement with EWN in February 1999 with the aim of utilizing all the decommissioning-related information and technologies accumulated by EWN since 1991. This report introduces 1) the status of the decommissioning which EWN has implemented at the Greifswald NPP; 2) project management practices which are required for efficient work; and 3) remote techniques for the reactor dismantling, these being important from a schedule point of view.

  19. Development of joint regulatory guidance on the management of higher activity radioactive wastes on nuclear licensed sites - 16095

    In 2006 the UK Government's response (1) to recommendations by its Committee on Radioactive Waste Management (CoRWM) established, in England and Wales, that geological disposal, supported by safe and secure interim storage, is the preferred route for the long-term management of higher-activity radioactive waste (i.e. that which is not suitable for near-surface disposal). It also gave the responsibility for delivering the programme for a deep geological repository to the Nuclear Decommissioning Authority (NDA). The Scottish Government has a policy of long term, near site, near surface safe and secure interim storage. To support the open and transparent approach promised by Government, the Health and Safety Executive (HSE), the Environment Agency and the Scottish Environment Protection Agency (SEPA) are developing joint guidance on the management of higher-activity radioactive waste to explain regulatory objectives in securing safe and secure interim storage and the associated management of radioactive wastes. The guidance comes in two parts: - Guidance on the regulatory process; - Technical guidance modules. The guidance promotes a cradle to grave approach to radioactive waste management and by aligning the regulatory interests of environmental and safety regulators it delivers one of the Government's 'Better Regulation' objectives. This paper describes the process by which the joint guidance was produced with particular emphasis on stakeholder engagement. It describes the key features of the guidance, including the concept of the radioactive waste management case (RWMC). Finally the problems encountered with dissemination and implementation are discussed together with measures taken by the regulators to improve these aspects.

  5. Source terms and releases in routine and accidental situations: the scheme implemented at the Joint Research Centre in Ispra for the evaluation of the dose to the population

    This paper presents the scheme and the tools implemented for the evaluation of the dose to the population due to the routine and emergency situations of the nuclear installations at the Joint Research Centre in Ispra. In particular, it will be introduced and discussed the use of models provided by commercial software and international technical recommendations. The approach for all the calculations required the usual conservative hypotheses, so that the maximum dose results have been derived. The dose evaluations have been performed retrospectively, for the years 1990-2002. The doses are evaluated net of the doses due to the naturally occurring radioactivity. (author)

  6. Fast joint detection-estimation of evoked brain activity in event-related fMRI using a variational approach

    2013-01-01

    International audience In standard within-subject analyses of event-related fMRI data, two steps are usually performed separately: detection of brain activity and estimation of the hemodynamic response. Because these two steps are inherently linked, we adopt the socalled region-based Joint Detection-Estimation (JDE) framework that addresses this joint issue using a multivariate inference for detection and estimation. JDE is built by making use of a regional bilinear generative model of the...

  8. State space approach for joint estimation of activity and attenuation map from PET emission sinograms

    Liu Huafeng; You Hongshun; Shi Pengcheng

    2007-01-01

    Quantitative estimation of radioactivity map has important clinical implications for better diagnosis and understanding of cancers. Although attenuation map and activity map are usually treated sequentially, they can obviously benefit a great deal when the transmission data is missing. In this paper, we propose a novel scheme of simultaneously solving for attenuation map and activity distribution from emission sinograms. Our strategy combines the measurement model of PET, and the attenuation parameters are treated as random variables with known prior statistics. After the conversion to state space representation, the extended Kalman filtering procedures are adopted to linearize the equations and to provide the joint estimates in an approximate optimal sense. Experiments have been performed on both synthetic data to illustrate its abilities and benefits.

    2010-01-01

    This paper is a report of an initial investigation into tracking and monitoring the integrity of bolted joints using piezoelectric active-sensors. The target application of this study is a fitting lug assembly of unmanned aerial vehicles (UAVs), where a composite wing is mounted to a UAV fuselage. The SHM methods deployed in this study are impedance-based SHM techniques, time-series analysis, and high-frequency response functions measured by piezoelectric active-sensors. Different types of simulated damage are introduced into the structure, and the capability of each technique is examined and compared. Additional considerations encountered in this initial investigation are made to guide further thorough research required for the successful field deployment of this technology.

  10. The mechanical and tribological properties of UHMWPE loaded ALN after mechanical activation for joint replacements.

    Gong, Kemeng; Qu, Shuxin; Liu, Yumei; Wang, Jing; Zhang, Yongchao; Jiang, Chongxi; Shen, Ru

    2016-08-01

    Ultra-high molecular weight polyethylene (UHMWPE) loaded with alendronate sodium (ALN) has tremendous potential as an orthopeadic biomaterial for joint replacements. However, poor mechanical and tribological properties of UHMWPE-ALN are still obstacle for further application. The purpose of this study was to investigate the effect and mechanism of mechanical activation on mechanical and tribological properties of 1wt% ALN-loaded UHMWPE (UHMWPE-ALN-ma). In this study, tensile test, small punch test and reciprocating sliding wear test were applied to characterize the mechanical and tribological properties of UHMWPE-ALN-ma. Scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and Fourier transform infrared spectroscopy (FTIR) were employed to characterize UHMWPE-ALN-ma. Tensile test and small punch test showed that Young׳s modulus, tensile strength and work-to-failure (WTF) of UHMWPE-ALN-ma increased significantly compared to those of UHMWPE-ALN. The friction coefficients and wear factors of UHMWPE-ALN-ma both decreased significantly compared to those of UHMWPE-ALN. Mechanical activation obviously reduced type 1 (void) and type 2 (the disconnected and dislocated machining marks) fusion defects of UHMWPE-ALN-ma, which were revealed by SEM images of freeze fracture surfaces after etching and lateral surfaces of specimens after extension to fracture, respectively. It was attributed to peeled-off layers and chain scission of molecular chains of UHMWPE particles after mechanical activation, which were revealed by SEM images and FTIR spectra of UHMWPE-ALN-ma and UHMWPE-ALN, respectively. Moreover, EDS spectra revealed the more homogeneous distribution of ALN in UHMWPE-ALN-ma compared to that of UHMWPE-ALN. The present results showed that mechanical activation was a potential strategy to improve mechanical and tribological properties of UHMWPE-ALN-ma as an orthopeadic biomaterial for joint replacements.

  11. Design and Implementation of Alkali Activated Cement For Sustainable Development

    Moseson, Alexander James

    Herein, progress is presented on the design and implementation of technology for sustainable development in general and international development in particular. Necessarily interdisciplinary, the work draws upon the tools and techniques of Mechanical, Materials, and Civil Engineering; and History & Politics. The work was conducted along two paths, the first being the theory and methodology of sustainable development. A flexible design and dissemination framework was developed, Technology Seeding, defined as: development by the transfer and participatory adaptation of appropriate proven conceptual designs. The methodology was developed in part through two case studies which implemented, respectively, wood-turning lathes in Tanzania and upland rice planters in Thailand. The second path is the design and investigation of alkali-activated cements (AACs) for practical use. Those developed herein, for US markets, comprise ground granulated blast furnace slag, soda ash (sodium carbonate), and up to 68 wt.% granular limestone. Mixture Design of Experiment (DOE) was utilized to guide empirical and theoretical analysis of performance (e.g. compressive strength), economic & ecological aspects (e.g. cost, CO2 production, energy consumption), and chemistry (e.g. Rietveld analysis of x-ray diffractograms). Models were derived to understand the impact of mix design on performance and for optimization. Successful formulations are hydraulic and cure at room temperature, with strengths as high as 41 MPa at 3 days and 65 MPa at 28 days. Some of these formulations, compared to OPC, are competitive in performance, reduce cost by up to 40%, and reduce both CO2 production and energy consumption by up to 97%. Major chemical products include calcium silicate hydrates / calcium aluminum silicate hydrates (C-(A)-S-H), gaylussite, and calcite (both newly formed and remaining from limestone). Calcite/dolomite and C-(A)-S-H both contribute to strength. A fraction of the limestone is consumed

  12. Muscle activation and estimated relative joint force during running with weight support on a lower-body positive pressure treadmill

    Jensen, Bente Rona; Hovgaard-Hansen, Line; Cappelen, Katrine Louise

    2016-01-01

    Running on a lower-body positive pressure (LBPP) treadmill allows effects of weight support on leg muscle activation to be assessed systematically, and has the potential to facilitate rehabilitation and prevent overloading. The aim was to study the effect of running with weight support on leg......, while activity of biceps femoris muscle remained unchanged. Unweighting with LBPP reduced estimated joint force significantly although less than proportional to the degree of weight support (ankle). It was concluded that leg muscle activation adapted to the new biomechanical environment, and the effect...... muscle activation and to estimate relative knee and ankle joint forces. Runners performed 6-min running sessions at 2.22 m/s and 3.33 m/s, at 100, 80, 60, 40 and 20% body-weight (BW). Surface EMG, ground reaction force and running characteristics were measured. Relative knee and ankle joint forces were...

  13. Temporal expectation and attention jointly modulate auditory oscillatory activity in the beta band.

    Ana Todorovic

    Full Text Available The neural response to a stimulus is influenced by endogenous factors such as expectation and attention. Current research suggests that expectation and attention exert their effects in opposite directions, where expectation decreases neural activity in sensory areas, while attention increases it. However, expectation and attention are usually studied either in isolation or confounded with each other. A recent study suggests that expectation and attention may act jointly on sensory processing, by increasing the neural response to expected events when they are attended, but decreasing it when they are unattended. Here we test this hypothesis in an auditory temporal cueing paradigm using magnetoencephalography in humans. In our study participants attended to, or away from, tones that could arrive at expected or unexpected moments. We found a decrease in auditory beta band synchrony to expected (versus unexpected tones if they were unattended, but no difference if they were attended. Modulations in beta power were already evident prior to the expected onset times of the tones. These findings suggest that expectation and attention jointly modulate sensory processing.

  14. Hedgehog inhibits β-catenin activity in synovial joint development and osteoarthritis

    Rockel, Jason S.; Yu, Chunying; Whetstone, Heather; Craft, April M.; Reilly, Katherine; Ma, Henry; Tsushima, Hidetoshi; Puviindran, Vijitha; Al-Jazrawe, Mushriq; Keller, Gordon M.; Alman, Benjamin A.

    2016-01-01

    Both the WNT/β-catenin and hedgehog signaling pathways are important in the regulation of limb development, chondrocyte differentiation, and degeneration of articular cartilage in osteoarthritis (OA). It is not clear how these signaling pathways interact in interzone cell differentiation and synovial joint morphogenesis. Here, we determined that constitutive activation of hedgehog signaling specifically within interzone cells induces joint morphological changes by selectively inhibiting β-catenin–induced Fgf18 expression. Stabilization of β-catenin or treatment with FGF18 rescued hedgehog-induced phenotypes. Hedgehog signaling induced expression of a dominant negative isoform of TCF7L2 (dnTCF7L2) in interzone progeny, which may account for the selective regulation of β-catenin target genes observed. Knockdown of TCF7L2 isoforms in mouse chondrocytes rescued hedgehog signaling–induced Fgf18 downregulation, while overexpression of the human dnTCF7L2 orthologue (dnTCF4) in human chondrocytes promoted the expression of catabolic enzymes associated with OA. Similarly, expression of dnTCF4 in human chondrocytes positively correlated with the aggrecanase ADAMTS4. Consistent with our developmental findings, activation of β-catenin also attenuated hedgehog-induced or surgically induced articular cartilage degeneration in mouse models of OA. Thus, our results demonstrate that hedgehog inhibits selective β-catenin target gene expression to direct interzone progeny fates and articular cartilage development and disease. Moreover, agents that increase β-catenin activity have the potential to therapeutically attenuate articular cartilage degeneration as part of OA. PMID:27018594

It is in the interests of both States and the IAEA to cooperate to facilitate the practical implementation of safeguards. Such cooperation is explicitly required under all types of safeguards agreement. Effective cooperation depends upon States and the IAEA sharing a common understanding of their respective rights and obligations. To address this, in 2012 the IAEA published Services Series 21, Guidance for States Implementing Comprehensive Safeguards Agreements and Additional Protocols, which aimed at enhancing understanding of the safeguards obligations of both States and the IAEA and at improving their cooperation in safeguards implementation. States may establish different processes and procedures at the national level, and set up different systems as required to meet their safeguards obligations. Indeed, a variety of approaches are to be expected, owing to such differences as the size and complexity of States’ nuclear programmes and their regulatory framework. The purpose of this Safeguards Implementation Practices (SIP) Guide is to share the experiences and good practices as well as the lessons learned by both States and the IAEA, acquired over the many decades of safeguards implementation. The information contained in the SIP Guides is provided for explanatory purposes and use of the Guides is not mandatory. The descriptions in the SIP Guides have no legal status and are not intended to add to, subtract from, amend or derogate from, in any way, the rights and obligations of the IAEA and the States set forth in The Structure and Content of Agreements between the Agency and States Required in Connection with the Treaty on the Non-Proliferation of Nuclear Weapons (issued as INFCIRC/153 (Corrected)) and Model Protocol Additional to the Agreement(s) between State(s) and the International Atomic Energy Agency for the Application of Safeguards (issued as INFCIRC/540 (Corrected)).

    This paper outlined the success of the 2003 Joint US and Canadian Coast Guard, US Navy and Industry Viscous Oil Pumping System (JVOPS) Workshop, which demonstrated the capabilities of the United States Coast Guard and the Canadian Coast Guard to respond to oil spills on water using their viscous oil pumping system (VOPS). A diverse group of marine pollution response stakeholders including industry engineers, scientists, pollution response equipment manufacturers and first responders worked jointly to identify methodologies for improving traditional pump transfer methods which have limitations for heavy oil response measures. Proposed enhancements incorporate methodologies such as hot water supply to the annual water injection flanges of the primary pump. This workshop evaluated such systems in a simulated response scenario for extreme viscosity and pumping distance. One hundred people from 7 countries participated in the pump transfer tests. Different types of hose cleaning technologies were used to investigate the start, stop and restart of the long distance transfer process. Some of the accomplishments of the workshop were: improved performance due to annulus water injection applied with hot water on the pump inlet; oil with 200,000 centistokes was pumped a distance of 450 m at nearly full pump capacity with a pressure drop of only 3 bar; and, oil with 500,000 centistokes was pumped a distance of 150 m at nearly full pump capacity with a pressure drop of only 0.9 bar. Further testing can experiment with different water lubrication settings against the measurement of various parameters such as pump discharge pressure, temperature at the inlet of the pump and the pumps hydraulic pumping unit (HPU) pressure. 4 refs., 2 tabs., 1 fig.

  1. ACTIVITY OF CANONICAL WNT SIGNAL SYSTEM IN HYALINE CARTILAGE ARTICULAR CHONDROCYTES IN PROCESS OF SYNOVIAL JOINT DEVELOPMENT

    A.O. Molotkov

    2009-03-01

    Full Text Available Canonical and non-canonical Wnt systems are essential regulators of chondrogenesis and bone development. However, the roles of these systems in synovial joint development are not well studied. To determine if canonical Wnt system is active in developing articular chondrocytes we used immunohistochemistry for в-galactosidase and doublecortin (cell-type specific marker for articular chondrocytes to double label sections through joint regions of E14.5, E18.5, P10 and adult mice. Here the following results are presented. Canonical Wnt signal system does not work in developing articular chondrocytes at early embryonic stages (E14.5; it is active in the articular chondrocytes at late embryonic stages (E16.5-E18.5 and during postnatal development (P7-P10, but is turned off again in the adult articular chondrocytes. These results suggest that canonical Wnt signaling is being regulated during articular chondrocytes differentiation and joint formation.

  6. Active Metal Brazing and Characterization of Brazed Joints in Titanium to Carbon-Carbon Composites

    Singh, M.; Shpargel, T. P.; Morscher, G. N.; Asthana, R.

    2006-01-01

    The Ti-metal/C-C composite joints were formed by reactive brazing with three commercial brazes, namely, Cu-ABA, TiCuNi, and TiCuSiI. The joint microstructures were examined using optical microscopy and scanning electron microscopy (SEM) coupled with energy dispersive spectrometry (EDS). The results of the microstructure analysis indicate solute redistribution across the joint and possible metallurgical bond formation via interdiffusion, which led to good wetting and spreading. A tube-on-plate tensile test was used to evaluate joint strength of Ti-tube/ C-C composite joints. The load-carrying ability was greatest for the Cu-ABA braze joint structures. This system appeared to have the best braze spreading which resulted in a larger braze/C-C composite bonded area compared to the other two braze materials. Also, joint loadcarrying ability was found to be higher for joint structures where the fiber tows in the outer ply of the C-C composite were aligned perpendicular to the tube axis when compared to the case where fiber tows were aligned parallel to the tube axis.

  8. Observational facts regarding the joint activities of the southwest vortex and plateau vortex after its departure from the Tibetan Plateau

    Yu, Shuhua; Gao, Wenliang; Xiao, Dixiang; Peng, Jun

    2016-01-01

    Using atmospheric observational data from 1998 to 2013, station rainfall data, TRMM (Tropical Rainfall Measuring Mission) data, as well as annual statistics for the plateau vortex and shear line, the joint activity features of sustained departure plateau vortexes (SDPVs) and southwest vortexes (SWVs) are analyzed. Some new and useful observational facts and understanding are obtained about the joint activities of the two types of vortex. The results show that: (1) The joint active period of the two vortexes is from May to August, and mostly in June and July. (2) The SDPVs of the partnership mainly originate near Zaduo, while the SWVs come from Jiulong. (3) Most of the two vortexes move in almost the same direction, moving eastward together with the low trough. The SDPVs mainly act in the area to the north of the Yangtze River, while the SWVs are situated across the Yangtze River valley. (4) The joint activity of the two vortexes often produces sustained regional heavy rainfall to the south of the Yellow River, influencing wide areas of China, and even as far as the Korean Peninsula, Japan and Vietnam. (5) Most of the two vortexes are baroclinic or cold vortexes, and they both become strengthened in terms of their joint activity. (6) When the two vortexes move over the sea, their central pressure descends and their rainfall increases, especially for SWVs. (7) The two vortexes might spin over the same area simultaneously when there are tropical cyclones in the eastern and southern seas of China, or move southward together if a tropical cyclone appears near Hainan Island.

  9. The mechanics of activated semitendinosus are not representative of the pathological knee joint condition of children with cerebral palsy.

    Ateş, Filiz; Temelli, Yener; Yucesoy, Can A

    2016-06-01

    Characteristic cerebral palsy effects in the knee include a restricted joint range of motion and forcefully kept joint in a flexed position. To show whether the mechanics of activated spastic semitendinosus muscle are contributing to these effects, we tested the hypothesis that the muscle's joint range of force exertion is narrow and force production capacity in flexed positions is high. The isometric semitendinosus forces of children with cerebral palsy (n=7, mean (SD)=7years (8months), GMFCS levels III-IV, 12 limbs tested) were measured intra-operatively as a function of knee angle, from flexion (120°) to full extension (0°). Peak force measured in the most flexed position was considered as the benchmark. However, peak force (mean (SD)=112.4N (54.3N)) was measured either at intermediate or even full knee extension (three limbs) indicating no narrow joint range of force exertion. Lack of high force production capacity in flexed knee positions (e.g., at 120° negligible or below 22% of the peak force) was shown except for one limb. Therefore, our hypothesis was rejected for a vast majority of the limbs. These findings and those reported for spastic gracilis agree, indicating that the patients' pathological joint condition must rely on a more complex mechanism than the mechanics of individual spastic muscles.

    Malfait, Bart; Dingenen, Bart; Smeets, Annemie; Staes, Filip; Pataky, Todd; Robinson, Mark A.; Vanrenterghem, Jos; Verschueren, Sabine

    2016-01-01

    Purpose The purpose was to assess if variation in sagittal plane landing kinematics is associated with variation in neuromuscular activation patterns of the quadriceps-hamstrings muscle groups during drop vertical jumps (DVJ). Methods Fifty female athletes performed three DVJ. The relationship between peak knee and hip flexion angles and the amplitude of four EMG vectors was investigated with trajectory-level canonical correlation analyses over the entire time period of the landing phase. EMG vectors consisted of the {vastus medialis(VM),vastus lateralis(VL)}, {vastus medialis(VM),hamstring medialis(HM)}, {hamstring medialis(HM),hamstring lateralis(HL)} and the {vastus lateralis(VL),hamstring lateralis(HL)}. To estimate the contribution of each individual muscle, linear regressions were also conducted using one-dimensional statistical parametric mapping. Results The peak knee flexion angle was significantly positively associated with the amplitudes of the {VM,HM} and {HM,HL} during the preparatory and initial contact phase and with the {VL,HL} vector during the peak loading phase (p<0.05). Small peak knee flexion angles were significantly associated with higher HM amplitudes during the preparatory and initial contact phase (p<0.001). The amplitudes of the {VM,VL} and {VL,HL} were significantly positively associated with the peak hip flexion angle during the peak loading phase (p<0.05). Small peak hip flexion angles were significantly associated with higher VL amplitudes during the peak loading phase (p = 0.001). Higher external knee abduction and flexion moments were found in participants landing with less flexed knee and hip joints (p<0.001). Conclusion This study demonstrated clear associations between neuromuscular activation patterns and landing kinematics in the sagittal plane during specific parts of the landing. These findings have indicated that an erect landing pattern, characterized by less hip and knee flexion, was significantly associated with an

  14. Estimation of the knee joint angle from surface electromyographic signals for active control of leg prostheses

    The surface electromyographic (SEMG) signal is very convenient for prosthesis control because it is non-invasively acquired and intrinsically related to the user's intention. This work presents a feature extraction and pattern classification algorithm for estimation of the intended knee joint angle from SEMG signals acquired using two sets of electrodes placed on the upper leg. The proposed algorithm uses a combination of time-domain and frequency-domain approaches for feature extraction (signal amplitude histogram and auto-regressive coefficients, respectively), a self-organizing map for feature projection and a Levenberg–Marquardt multi-layer perceptron neural network for pattern classification. The new algorithm was quantitatively compared with the method proposed by Wang et al (2006 Med. Biol. Eng. Comput. 44 865–72), which uses wavelet packet feature extraction, principal component analysis and a multi-layer perceptron neural classifier. The proposed method provided lower error-to-signal percentage and peak error amplitudes, higher correlation and fewer error events. The algorithm presented in this work may be useful as part of a myoelectric controller for active leg prostheses designed for transfemoral amputees

  15. Bio-Inspired Control of an Arm Exoskeleton Joint with Active-Compliant Actuation System

    Michele Folgheraiter

    2009-01-01

    Full Text Available This paper presents the methodology followed on the design of a multi-contact point haptic interface that uses a bio-inspired control approach and a novel actuation system. The combination of these components aims at creating a system that increases the operability of the target, and, at the same time, enables an intuitive and safe tele-operation of any complex robotic system of any given morphology. The novelty lies on the combination of a thoughtful kinematic structure driven by an active-compliant actuation system and a bio-inspired paradigm for its regulation. Due to the proposed actuation approach, the final system will achieve the condition of wearable system. On that final solution, each joint will be able to change its stiffness depending on the task to be executed, and on the anatomical features of each individual. Moreover, the system provides a variety of safety mechanisms at different levels to prevent causing any harm to the operator. In future, the system should allow the complete virtual immersion of the user within the working scenario.

    2014-07-01

    Full Text Available There has been limited research on genome-wide association with physical activity (PA. This study ascertained genetic associations between PA and 344,893 single nucleotide polymorphism (SNP markers in 8842 Korean samples. PA data were obtained from a validated questionnaire that included information on PA intensity and duration. Metabolic equivalent of tasks were calculated to estimate the total daily PA level for each individual. In addition to single- and multiple-SNP association tests, a pathway enrichment analysis was performed to identify the biological significance of SNP markers. Although no significant SNP was found at genome-wide significance level via single-SNP association tests, 59 genetic variants mapped to 76 genes were identified via a multiple SNP approach using a bootstrap selection stability measure. Pathway analysis for these 59 variants showed that maturity onset diabetes of the young (MODY was enriched. Joint identification of SNPs could enable the identification of multiple SNPs with good predictive power for PA and a pathway enriched for PA.

  17. Preparing for Construction and Operation of Geological Repositories - Challenges to the Regulator and the Implementer. Proceedings of the Joint RF/IGSC Workshop, Issy-les-Moulineaux, France, 25-27 January 2012

    More radioactive waste management programmes are advancing to a new repository development phase and are preparing for the application of their construction license of a deep geological disposal facility. Such developmental progress brought along significant changes to repository development affecting both the waste management programme implementers and the regulators. New issues impacting both the regulatory authorities and the future facility operators include operational safety and reliability, increased demands on human resources, activities to ensure quality assurance, the additional requirements on information management system and management plans for construction work. To respond to new arising issues, the Radioactive Waste Management Committee (RWMC) of the OECD Nuclear Energy Agency (NEA) has agreed, as stated in the 2011-2016 Strategic Plan, that the Committee will focus on constituencies for the preparation of the construction and operation license of future deep geological repositories. In addition, the Committee will consider operational aspects of repository implementation, both connected to the operational safety and the impact on the post-closure long-term safety. In particular, the RWMC has approved the RWMC Regulator's Forum (RWMC-RF) and the Integration Group for the Safety Case (IGSC) to hold a joint workshop to explore challenging issues and practices in preparing for the application of the construction license of a geological repository. The joint workshop titled 'Preparing for Construction and Operation of Geological Repositories - Challenges to the Regulator and the Implementer' was held on January 25-27, 2012 at the NEA premises in Issy-les-Moulineaux, France. The key objective of the workshop was to identify, and exchange experience on, the current and future challenges faced by the implementers and the regulators when preparing for their application of a construction license of a geological repository. The workshop gave a

    Full Text Available As an attempt to increase the resistance to Newcastle Disease Virus (NDV and so further reduction of its risk on the poultry industry. This work aimed to build the eukaryotic gene co-expression plasmid of neuraminidase (NA gene and myxo-virus resistance (Mx and detect the gene expression in transfected mouse fibroblasts (NIH-3T3 cells, it is most important to investigate the influence of the recombinant plasmid on the chicken embryonic fibroblasts (CEF cells. cDNA fragment of NA and mutant Mx gene were derived from pcDNA3.0-NA and pcDNA3.0-Mx plasmid via PCR, respectively, then NA and Mx cDNA fragment were inserted into the multiple cloning sites of pVITRO2 to generate the eukaryotic co-expression plasmid pVITRO2-Mx-NA. The recombinant plasmid was confirmed by restriction endonuclease treatment and sequencing, and it was transfected into the mouse fibroblasts (NIH-3T3 cells. The expression of genes in pVITRO2-Mx-NA were measured by RT-PCR and indirect immunofluorescence assay (IFA. The recombinant plasmid was transfected into CEF cells then RT-PCR and the micro-cell inhibition tests were used to test the antiviral activity for NDV. Our results showed that co-expression vector pVITRO2-Mx-NA was constructed successfully; the expression of Mx and NA could be detected in both NIH-3T3 and CEF cells. The recombinant proteins of Mx and NA protect CEF cells from NDV infection until after 72 h of incubation but the individually mutagenic Mx protein or NA protein protects CEF cells from NDV infection till 48 h post-infection, and co-transfection group decreased significantly NDV infection compared with single-gene transfection group (P<0. 05, indicating that Mx-NA jointing contributed to delaying the infection of NDV in single-cell level and the co-transfection of the jointed genes was more powerful than single one due to their synergistic effects.

  20. Technetium-99m human polyclonal immunoglobulin g studies and conventional bone scans to detect active joint inflammation in chronic rheumatoid arthritis

    Rheumatoid arthritis is a chronic polyarthritis in which active inflammed joints coexist with joints in remission. We performed bone scans (99mTc-DPD) and 99mTc human polyclonal immunoglobulin G scans (99mTc-IgG) in 18 patients with rheumatoid arthritis to assess the uptake in actively inflammed joints and in joints in which remission after inflammation had occurred. A quantitative analysis of tracer uptake in each joint was performed on both scans. In 123 joints without current active inflammation, an increased 99mTc-DPD uptake was observed (2.31±1.27), whereas no 99mTc-IgG uptake was noted (1.18±0.32). Some 78 joints with mild pain or swelling exhibited increased 99mTc-DPD uptake (2.48±1.14) and increased 99mTc-IgG uptake (1.76±0.50; P99mTc-DPD uptake (2.39±0.93) and increased 99mTc-IgG uptake (1.79±0.51; P99mTc-IgG scans distinguish between joints with and without active inflammation in chronic rheumatoid arthritis, whereas bone scans do not. Thus, 99mTc-IgG scans may be useful in identifying joints with current active inflammation in rheumatoid arthritis. (orig.)

  2. Baseband Transceiver Design of a High Definition Radio FM System Using Joint Theoretical Analysis and FPGA Implementation

    Chien-Sheng Chen

    2014-01-01

    Full Text Available Advances in wireless communications have enabled various technologies for wireless digital communication. In the field of digital radio broadcasting, several specifications have been proposed, such as Eureka-147 and digital radio mondiale (DRM. These systems require a new spectrum assignment, which incurs heavy cost due to the depletion of the available spectrum. Therefore, the in-band on-channel (IBOC system has been developed to work in the same band with the conventional analog radio and to provide digital broadcasting services. This paper discusses the function and algorithm of the high definition (HD radio frequency modulation (FM digital radio broadcasting system. Content includes data format allocation, constellation mapping, orthogonal frequency division multiplexing (OFDM modulation of the transmitter, timing synchronization, OFDM demodulation, integer and fraction carrier frequency (integer carrier frequency offset (ICFO and fractional CFO (FCFO estimation, and channel estimation of the receiver. When we implement this system to the field programmable gate array (FPGA based on a hardware platform, both theoretical and practical aspects have been considered to accommodate the available hardware resources.

  3. Effects of activating fluxes on the weld penetration and corrosion resistant property of laser welded joint of ferritic stainless steel

    Wang, Yonghui; Hu, Shengsun; Shen, Junqi

    2015-10-01

    This study was based on the ferritic stainless steel SUS430. Under the parallel welding conditions, the critical penetration power values (CPPV) of 3mm steel plates with different surface-coating activating fluxes were tested. Results showed that, after coating with activating fluxes, such as ZrO2, CaCO3, CaF2 and CaO, the CPPV could reduce 100~250 W, which indicating the increases of the weld penetrations (WP). Nevertheless, the variation range of WP with or without activating fluxes was less than 16.7%. Compared with single-component ones, a multi-component activating flux composed of 50% ZrO2, 12.09% CaCO3, 10.43% CaO, and 27.49% MgO was testified to be much more efficient, the WP of which was about 2.3-fold of that without any activating fluxes. Furthermore, a FeCl3 spot corrosion experiment was carried out with samples cut from weld zone to test the effects of different activating fluxes on the corrosion resistant (CR) property of the laser welded joints. It was found that all kinds of activating fluxes could improve the CR of the welded joints. And, it was interesting to find that the effect of the mixed activating fluxes was inferior to those single-component ones. Among all the activating fluxes, the single-component of CaCO3 seemed to be the best in resisting corrosion. By means of Energy Dispersive Spectrometer (EDS) testing, it was found that the use of activating fluxes could effectively restrain the loss of Cr element of weld zone in the process of laser welding, thus greatly improving the CR of welded joints.

    IIEC, a division of CERF, has developed an extensive base of experience implementing activities that support climate action by developing USIJI projects in transitional countries within Asia, Latin America, Central and Eastern Europe, and southern Africa. IIEC has been able to provide a range of technical and policy assistance to governments and industry in support of sustainable energy use. IIEC continues to work in key countries with local partners to develop and implement energy efficiency policies and standards, develop site-specific projects, and assist governing bodies to establish national priorities and evaluation criteria for approving GHG-mitigation projects. As part of this project, IIEC focused on promoting a series of activities in Thailand and South Africa in order to identify GHG mitigation projects and work within the national approval process of those countries. The sections of this report outline the activities conducted in each country in order to achieve that goal.

  5. Determinants of Implementation Effectiveness in a Physical Activity Program for Church-Going Latinas.

    Beard, Megan; Chuang, Emmeline; Haughton, Jessica; Arredondo, Elva M

    2016-01-01

    Faith-based interventions show promise for reducing health disparities among ethnic minority populations. However, churches vary significantly in their readiness and willingness to support these programs. Semistructured interviews were conducted with priests, other church leaders, and lay health advisors in churches implementing a physical activity intervention targeting Latinas. Implementation effectiveness was operationalized as average 6-month participation rates in physical activity classes at each church. Factors facilitating implementation include church leader support and strength of parishioners' connection to the church. Accounting for these church-level factors may be critical in determining church readiness to participate in health promotion activities. PMID:27536927

  7. An fMRI study of joint action–varying levels of cooperation correlates with activity in control networks

    Chaminade, Thierry; Marchant, Jennifer L.; Kilner, James; Frith, Christopher D.

    2012-01-01

    As social agents, humans continually interact with the people around them. Here, motor cooperation was investigated using a paradigm in which pairs of participants, one being scanned with fMRI, jointly controlled a visually presented object with joystick movements. The object oscillated dynamically along two dimensions, color and width of gratings, corresponding to the two cardinal directions of joystick movements. While the overall control of each participant on the object was kept constant, the amount of cooperation along the two dimensions varied along four levels, from no (each participant controlled one dimension exclusively) to full (each participant controlled half of each dimension) cooperation. Increasing cooperation correlated with BOLD signal in the left parietal operculum and anterior cingulate cortex (ACC), while decreasing cooperation correlated with activity in the right inferior frontal and superior temporal gyri, the intraparietal sulci and inferior temporal gyri bilaterally, and the dorsomedial prefrontal cortex. As joint performance improved with the level of cooperation, we assessed the brain responses correlating with behavior, and found that activity in most of the areas associated with levels of cooperation also correlated with the joint performance. The only brain area found exclusively in the negative correlation with cooperation was in the dorso medial frontal cortex, involved in monitoring action outcome. Given the cluster location and condition-related signal change, we propose that this region monitored actions to extract the level of cooperation in order to optimize the joint response. Our results, therefore, indicate that, in the current experimental paradigm involving joint control of a visually presented object with joystick movements, the level of cooperation affected brain networks involved in action control, but not mentalizing.

    As social agents, humans continually interact with the people around them. Here, motor cooperation was investigated using a paradigm in which pairs of participants, one being scanned with fMRI, jointly controlled a visually presented object with joystick movements. The object oscillated dynamically along two dimensions, color and width of gratings, corresponding to the two cardinal directions of joystick movements. While the overall control of each participant on the object was kept constant, the amount of cooperation along the two dimensions varied along four levels, from no (each participant controlled one dimension exclusively) to full (each participant controlled half of each dimension) cooperation. Increasing cooperation correlated with BOLD signal in the left parietal operculum and anterior cingulate cortex (ACC), while decreasing cooperation correlated with activity in the right inferior frontal and superior temporal gyri, the intraparietal sulci and inferior temporal gyri bilaterally, and the dorsomedial prefrontal cortex. As joint performance improved with the level of cooperation, we assessed the brain responses correlating with behavior, and found that activity in most of the areas associated with levels of cooperation also correlated with the joint performance. The only brain area found exclusively in the negative correlation with cooperation was in the dorso medial frontal cortex, involved in monitoring action outcome. Given the cluster location and condition-related signal change, we propose that this region monitored actions to extract the level of cooperation in order to optimize the joint response. Our results, therefore, indicate that, in the current experimental paradigm involving joint control of a visually presented object with joystick movements, the level of cooperation affected brain networks involved in action control, but not mentalizing.

  10. NRF2 Activation as Target to Implement Therapeutic Treatments

    Bocci, Velio; Valacchi, Giuseppe

    2015-02-01

    A chronic increase of oxidative stress is typical of serious pathologies such as myocardial infarction, stroke, chronic limb ischemia, chronic obstructive pulmonary disease (COPD), type II-diabetes, age-related macular degeneration leads to an epic increase of morbidity and mortality in all countries of the world. The initial inflammation followed by an excessive release of reactive oxygen species (ROS) implies a diffused cellular injury that needs to be corrected by an inducible expression of the innate detoxifying and antioxidant system. The transcription factor Nrf2, when properly activated, is able to restore a redox homeostasis and possibly improve human health.

  12. Implementation Considerations for Active Noise Control in Ventilation Systems

    Asteborg, Marcus; Svanberg, Niklas

    2006-01-01

    The most common method to attenuate noise in ventilation systems today is passive silencers. For these to efficiently attenuate frequencies below 400 Hz such silencers need to be large and a more neat solution to attenuate low frequencies is to use active noise control (ANC). The usage of ANC in ventilation systems is well known and there are several commercial products available. ANC is not, however, used on a wide basis due to its often high price and poor performance. Since the price is an...

    Full Text Available Many businesses have obtained cheap raw materials thanks to recycling and recovery activities. The aim of this study is to describe the logistics activities performed by businesses and to identify the main reasons of reverse logistics appliance. The research is a case study defined as “integrated  multi-case design” type. For this purpose, 23 industrial enterprises were examined in the scope of sample. Because the data obtained via unstructured interview form, they have qualitative characters. The single answers were used as analysis unit in this study, descriptive and discourse analyses were performed on qualitative data. Some sentences were quoted directly. The obtained results were submitted to the approval of the respondents. Thereby, it was contributed to construct validity of the research by creating evidence chain. It seems reasonable to conclude that the most commonly applied ones among reverse logistics operations are storing, selling to a mediary, destruction, recycling, regulation of customer returns new repackaging and resale. The results showed that reverse logistics operations were performed for some reasons such as providing raw materials, saving in production, raising the level of consciousness of environmental responsibility and awareness taking part in social responsibility project and consumer rights.

  16. Learning dictionaries of sparse codes of 3D movements of body joints for real-time human activity understanding.

    Jin Qi

    Full Text Available Real-time human activity recognition is essential for human-robot interactions for assisted healthy independent living. Most previous work in this area is performed on traditional two-dimensional (2D videos and both global and local methods have been used. Since 2D videos are sensitive to changes of lighting condition, view angle, and scale, researchers begun to explore applications of 3D information in human activity understanding in recently years. Unfortunately, features that work well on 2D videos usually don't perform well on 3D videos and there is no consensus on what 3D features should be used. Here we propose a model of human activity recognition based on 3D movements of body joints. Our method has three steps, learning dictionaries of sparse codes of 3D movements of joints, sparse coding, and classification. In the first step, space-time volumes of 3D movements of body joints are obtained via dense sampling and independent component analysis is then performed to construct a dictionary of sparse codes for each activity. In the second step, the space-time volumes are projected to the dictionaries and a set of sparse histograms of the projection coefficients are constructed as feature representations of the activities. Finally, the sparse histograms are used as inputs to a support vector machine to recognize human activities. We tested this model on three databases of human activities and found that it outperforms the state-of-the-art algorithms. Thus, this model can be used for real-time human activity recognition in many applications.

  17. Activation of β-catenin signalling leads to temporomandibular joint defects

    2014-10-01

    Full Text Available Despite extensive research in knee and hip osteoarthritis (OA, the underlying mechanism of temporomandibular joint (TMJ disorder remains largely unknown. The purpose of this study was to determine whether the constitutive activation of β-catenin in the middle and deep layers of the articular cartilage can compromise the homeostasis of this tissue in the TMJ. Col2CreERT2 transgenic mice were bred with RosamT/mG reporter mice to determine Cre recombination efficiency. Col2CreERT2 mice were then crossed with β-cateninflox(ex3+ mice to generate β-catenin conditional activation mice, β-catenin(ex3Col2ER. TMJ samples were harvested when the mice were 1-, 3- or 6-month-old and evaluated using histology, histomorphometry and immunohistochemistry. β-catenin(ex3Col2ER mice were further crossed with Mmp13flox/flox and Adamts5-/- mice to generate (β-catenin(ex3/Mmp13Col2ER and β-catenin(ex3Col2ER/Adamts5-/- double mutant mice to investigate the role of Mmp13 and Adamts5 in the development of TMJ disorder. High levels of Cre-recombination were seen in Col2CreERT2;RosamT/mGmice. Progressive TMJ defects developed in 1-, 3- and 6-month-old β-catenin(ex3Col2ER mice, as revealed by histology and histomorphometry. Results further demonstrated that the defects observed in β-catenin(ex3Col2ER mice were significantly decelerated after deletion of the Mmp13 or Adamts5 gene in (β-catenin(ex3/Mmp13Col2ER or β-catenin(ex3Col2ER/Adamts5-/- double mutant mice. In summary, we found that β-catenin is a critical gene in the induction of TMJ cartilage degeneration, and over-expressing β-catenin in TMJ cartilage leads to defects assembling an OA-like phenotype. Deletion of Mmp13 and Adamts5 in β-catenin(ex3Col2ER mice ameliorates the development of TMJ defects. This study suggests that Mmp13 and Adamts5 could be potential therapeutic targets for the treatment of TMJ disorders.

  20. From design to implementation - The Joint Asia Diabetes Evaluation (JADE program: A descriptive report of an electronic web-based diabetes management program

    Lyubomirsky Greg

    2010-05-01

    Full Text Available Abstract Background The Joint Asia Diabetes Evaluation (JADE Program is a web-based program incorporating a comprehensive risk engine, care protocols, and clinical decision support to improve ambulatory diabetes care. Methods The JADE Program uses information technology to facilitate healthcare professionals to create a diabetes registry and to deliver an evidence-based care and education protocol tailored to patients' risk profiles. With written informed consent from participating patients and care providers, all data are anonymized and stored in a databank to establish an Asian Diabetes Database for research and publication purpose. Results The JADE electronic portal (e-portal: http://www.jade-adf.org is implemented as a Java application using the Apache web server, the mySQL database and the Cocoon framework. The JADE e-portal comprises a risk engine which predicts 5-year probability of major clinical events based on parameters collected during an annual comprehensive assessment. Based on this risk stratification, the JADE e-portal recommends a care protocol tailored to these risk levels with decision support triggered by various risk factors. Apart from establishing a registry for quality assurance and data tracking, the JADE e-portal also displays trends of risk factor control at each visit to promote doctor-patient dialogues and to empower both parties to make informed decisions. Conclusions The JADE Program is a prototype using information technology to facilitate implementation of a comprehensive care model, as recommended by the International Diabetes Federation. It also enables health care teams to record, manage, track and analyze the clinical course and outcomes of people with diabetes.

  1. Effect of Multipass TIG and Activated TIG Welding Process on the Thermo-Mechanical Behavior of 316LN Stainless Steel Weld Joints

    Ganesh, K. C.; Balasubramanian, K. R.; Vasudevan, M.; Vasantharaja, P.; Chandrasekhar, N.

    2016-04-01

    The primary objective of this work was to develop a finite element model to predict the thermo-mechanical behavior of an activated tungsten inert gas (ATIG)-welded joint. The ATIG-welded joint was fabricated using 10 mm thickness of 316LN stainless steel plates in a single pass. To distinguish the merits of ATIG welding process, it was compared with manual multipass tungsten inert gas (MPTIG)-welded joint. The ATIG-welded joint was fabricated with square butt edge configuration using an activating flux developed in-house. The MPTIG-welded joint was fabricated in thirteen passes with V-groove edge configuration. The finite element model was developed to predict the transient temperature, residual stress, and distortion of the welded joints. Also, microhardness, impact toughness, tensile strength, ferrite measurement, and microstructure were characterized. Since most of the recent publications of ATIG-welded joint was focused on the molten weld pool dynamics, this research work gives an insight on the thermo-mechanical behavior of ATIG-welded joint over MPTIG-welded joint.

  2. Development of HIP bonding procedure and mechanical properties of HIP bonded joints for reduced activation ferritic steel F-82H

    Structural materials of blanket components in fusion DEMO reactors will receive a neutron wall load more than 3-5MW/m2 as well as exposed by surface heat flux more than 0.5MW/m2. A reduced activation ferritic steel F-82H has been developed by JAERI in collaboration with NKK from viewpoints of resistance for high temperature and neutron loads and lower radioactivity. This study intends to obtain basic performance of F-82H to establish the fabrication procedure of the first wall and blanket box by using Hot Isostatic Pressing (HIP) bonding. Before HIP bonding tests, effects of heat treatment temperature and surface roughness on mechanical properties of joints were investigated in the heat treatment tests and diffusion bonding tests, respectively. From these results, the optimum HIP bonding conditions and the post heat treatment were selected. Using these conditions, the HIP bonding tests were carried out to evaluate HIP bondability and to obtain mechanical properties of the joints. Sufficient HIP bonding performance was obtained under the temperature of 1040degC, the compressive stress of 150MPa, the holding time of 2h, and the surface roughness ∼μ m. Mechanical properties of HIP bonded joints with these conditions were similar to those of as-received base metal. An oxide formation on the surface to be bonded would need to be avoided for sufficient bonding. The bonding ratio, Charpy impact value and fatigue performance of the joints strongly depended on the HIP conditions, especially temperature, while micro-structure, Vickers hardness and tensile properties had little dependence on the HIP temperature. The surface roughness strongly affected the bonding ratio and would be required to be in the level of a few μ m. In the HIP bonding test of the welded material, the once-melted surface could be jointed by the HIP bonding under the above-mentioned procedure. (J.P.N.)

  3. Improved clean development mechanism and joint implementation to promote holistic sustainable development - an integrated policy and methodology for international energy collaboration

    Kua Harn Wei

    2007-07-01

    The current Clean Development Mechanism/Joint Implementation framework does not emphasize on wholistic sustainability of energy projects. The Golden Standard was a good example of how this framework can be fine-tuned. However, it does not explicitly incentivize the adoption of the sustainability standards it outlines. A 4-element integrated policy strategy is proposed. A Sustainability Assessment Matrix is constructed to evaluate project proposals' sustainability performance. The Probational Sustainability Performance Demand requires continual monitoring of this performance of approved projects throughout a designated probation period. The involved countries will be awarded Sustainability Credits (measured with the matrix) in installments according to their performance within this period. The Probational Emission Reduction Demand requires investing countries to meet moderated emission reduction targets in order for them to claim the certified emission reductions/ emission reduction credits and their share of Sustainability Credits. These credits are converted into Sustainability Assistance Funds, which can be channeled back to finance either the approved projects or independent renewable energy projects in the involved countries. The MIT Energy Cost Model is used to estimate the required amount and identify the forms of such assistance package. Finally, an integrated policymaking framework is suggested to execute and monitor these interconnected policy elements. (auth)

  4. The Joint Cities

    Romano Fistola

    2010-04-01

    Full Text Available The new connections, which high speed train allows to activate among the metropolitan systems, seem to be able to give life to new urban macro-structures for which the transfer time, among the main poles of the railway segment, becomes comparable to an inside moving into the city and therefore considered as an inter-functional mobility. The tunnel effect generated by the high speed connection seems to be able to allow a new temporal and functional joint among the metropolitan systems consequently supporting the possibility, for the users, to move themselves among the different urban functions belonging to the different cities. The birth of these urban aggregations seems to drive towards new megalopolis, which we can define for the first time with the term: joint-city. For this new metropolitan settlement it seems to be very interesting to investigate the constitutive peculiarities, the systemic articulation, its relational structures, the evolutionary scenarios, and so on. The urban functions (activities can be considered as structures of relationships between people that allows to define "organizational links" inside the community; the urban functions are located in specific places inside urban container or in open spaces. The urban functions represent the urban engines and the functional system can be thought as the “soul of the city", abstract but essential to its survival. In the definition set out here the analysis is carried out for many interconnected urban functional system points (specifically those in Rome and Naples. The new high speed railway has to be considered not only as a new channel of mobility between cities, but as a real possibility of joint between the functional systems of the two centres. A final consideration can be carried out in relation to the possibility of implementing new measures of governance of urban transformations considering the new macro-city: the "Joint City".

  5. Joint imaging

    Joint imaging is a proven diagnostic procedure which has become indispensable to the detection and treatment of different joint diseases in almost all disciplines. The method is suited for early diagnosis of joint affections both in soft tissue and bone which cannot be detected by X-ray or other procedures. The local activity accumulation depends on the rate of metabolism and is visualized in the scan, which in turn enables the extension and floridity of focal lesions to be evaluated and followed-up. Although joint scans may often give hints to probabilities relevant to differential diagnosis, the method is non-specific and only useful if based on the underlying clinical picture and X-ray finding, if possible. The radiation exposure is very low and does not represent a hazard in cases of adequate assessment of indication. In pregnant women and children the assessment of indication has to be based on very strict principles. The method is suited for out-patient diagnosis and can be applied in all installations equipped with a gamma camera and a technetium generator. (orig.)

  6. Temporomandibular joint inflammation activates glial and immune cells in both the trigeminal ganglia and in the spinal trigeminal nucleus

    Jasmin Luc

    2010-12-01

    Full Text Available Abstract Background Glial cells have been shown to directly participate to the genesis and maintenance of chronic pain in both the sensory ganglia and the central nervous system (CNS. Indeed, glial cell activation has been reported in both the dorsal root ganglia and the spinal cord following injury or inflammation of the sciatic nerve, but no data are currently available in animal models of trigeminal sensitization. Therefore, in the present study, we evaluated glial cell activation in the trigeminal-spinal system following injection of the Complete Freund's Adjuvant (CFA into the temporomandibular joint, which generates inflammatory pain and trigeminal hypersensitivity. Results CFA-injected animals showed ipsilateral mechanical allodynia and temporomandibular joint edema, accompanied in the trigeminal ganglion by a strong increase in the number of GFAP-positive satellite glial cells encircling neurons and by the activation of resident macrophages. Seventy-two hours after CFA injection, activated microglial cells were observed in the ipsilateral trigeminal subnucleus caudalis and in the cervical dorsal horn, with a significant up-regulation of Iba1 immunoreactivity, but no signs of reactive astrogliosis were detected in the same areas. Since the purinergic system has been implicated in the activation of microglial cells during neuropathic pain, we have also evaluated the expression of the microglial-specific P2Y12 receptor subtype. No upregulation of this receptor was detected following induction of TMJ inflammation, suggesting that any possible role of P2Y12 in this paradigm of inflammatory pain does not involve changes in receptor expression. Conclusions Our data indicate that specific glial cell populations become activated in both the trigeminal ganglia and the CNS following induction of temporomandibular joint inflammation, and suggest that they might represent innovative targets for controlling pain during trigeminal nerve sensitization.

  7. Neutron activation studies of the in-body corrosion of hip-joint prostheses made of Co-Cr alloys

    Using instrumental neutron activation analysis (INAA) the trace element composition of 18 elements was investigated in human tissues (articular capsule and fascia lata) of 36 persons after removal of hip-joint prostheses made of Co-Cr alloys. Normal trace element concentrations were determined studying a group of 26 patients before receiving their first artificial hip-joint. The tissues of patients with metal implants exhibited a heavy burdening by corrosion products (Co, Cr, Ni) from the prostheses as well as by Zr, Hf and Ba from the bone cements. Moreover, changes in the distribution of trace elements not contained in the steel were also observed. A comparison of the analytical results with those of model experiments of the corrosion of Co-Cr alloy in Ringer's solution demonstrates that the distribution pattern of corrosion products in the tissues are influenced by both, the biochemical properties as well as by selective dissolution of the alloy constituents.

  8. Total joint replacement: A multiple risk factor analysis of physical activity level 1-2 years postoperatively.

    Paxton, Elizabeth W; Torres, Andy; Love, Rebecca M; Barber, Thomas C; Sheth, Dhiren S; Inacio, Maria C S

    2016-07-01

    Background and purpose - The effect of total joint arthroplasty (TJA) on physical activity is not fully understood. We investigated the change in physical activity after TJA and patient factors associated with change. Patients and methods - Using a total joint replacement registry, primary total hip arthroplasty (THA) patients (n = 5,678) and knee arthroplasty (TKA) patients (n = 11,084) between January 1, 2010 and December 31, 2012 were identified. Median age at THA was 68 and median age at TKA was 67. Change in self-reported physical activity (minutes per week) from before TJA (within 1 year of surgery) to after TJA (1-2 years) was the outcome of interest. Patient demographics and comorbidities were evaluated as risk factors. Multiple linear regression was used. Results - Median physical activity before surgery was 50 min/week (IQR: 0-140) for THA patients and 58 (IQR: 3-143) for TKA patients. Median physical activity after surgery was 150 min/week (IQR: 60-280) for both THA patients and TKA patients. Following TJA, 50% of patients met CDC/WHO physical activity guideline criteria. Higher body mass index was associated with lower change in physical activity (THA: -7.1 min/week; TKA: -5.9 min/week). Females had lower change than males (THA: -11 min/week; TKA: -9.1 min/week). In TKA patients, renal failure was associated with lower change (-17 min/week), as were neurological disorders (-30 min/week). Interpretation - Self-reported minutes of physical activity increased from before to after TJA, but 50% of TJA patients did not meet recommended physical activity guideline criteria. Higher body mass index, female sex, and specific comorbidities were found to be associated with low change in physical activity. Patient education on the benefits of physical activity should concentrate on these subgroups of patients. PMID:27299567

  9. Benefits from joint research activities by universities and national institutions for nuclear programmes in a developing country

    In a developing country such as Greece where a nuclear power programme is under consideration and faces special problems, collaboration between universities and national institutions in joint research projects, besides helping to obtain valuable results, is the best way to benefit both parties in their individual programmes. Ten years ago a joint research programme between the Control Group of the University of Patras and subsequently the National Technical University of Athens (NTUA) on the one side, and the Group of Research Reactor Modelling, Reliability and Failure Detection of the Nuclear Technology Department of the NRCPS 'Democritos' on the other, was established. The co-operation proved to be fruitful as regards (a) exchanging information and know-how relating to academically oriented activities and nuclear reactor and laboratory experiments and research; (b) working in joint research programmes on systems control theory and applications to nuclear reactors; and (c) training of post-graduate students in theory and applications as well as in methods and techniques used in a nuclear laboratory. Particular areas of joint activity and research are nuclear reactor modelling, simulation and identification; control theory methodology as applied to nuclear reactors; treatment of nuclear power systems using large scale systems techniques; microprocessor-based systems for nuclear reactor measurements, data acquisition and nuclear signal processing and control; analysis and optimization of system reliability and maintenance with application to nuclear reactor systems; dynamic failure detection of nuclear systems using state observers and filters; and application of knowledge-based systems and artificial intelligence techniques to nuclear reactor systems (evaluation, operation, maintenance and safety procedures). Naturally, this co-operation has contributed to the preparation of the necessary manpower for carrying out research and practical work in the systems and

  12. An analysis of a joint shear model for jointed media with orthogonal joint sets

    This report describes a joint shear model used in conjunction with a computational model for jointed media with orthogonal joint sets. The joint shear model allows nonlinear behavior for both joint sets. Because nonlinear behavior is allowed for both joint sets, a great many cases must be considered to fully describe the joint shear behavior of the jointed medium. An extensive set of equations is required to describe the joint shear stress and slip displacements that can occur for all the various cases. This report examines possible methods for simplifying this set of equations so that the model can be implemented efficiently form a computational standpoint. The shear model must be examined carefully to obtain a computationally efficient implementation that does not lead to numerical problems. The application to fractures in rock is discussed. 5 refs., 4 figs

  16. Implementation of the EU-policy framework WFD and GWD in Europe - Activities of CIS Working Group Groundwater

    Grath, Johannes; Ward, Rob; Hall, Anna

    2013-04-01

    At the European level, the basic elements for groundwater management and protection are laid down in the Water Framework Directive (WFD) (2000/60/EC) and the Groundwater Daughter Directive (2006/118/EC). EU Member States, Norway and the European Commission (EC) have jointly developed a common strategy for supporting the implementation of the WFD. The main aim of this Common Implementation Strategy (CIS) is to ensure the coherent and harmonious implementation of the directives through the clarification of a number of methodological questions enabling a common understanding to be reached on the technical and scientific implications of the WFD (European Communities, 2008). Groundwater specific issues are dealt with in Working Group C Groundwater. Members of the working group are experts nominated by Member states, Norway, Switzerland and Accession Countries (from administrative bodies, research institutes, …) and representatives from relevant stakeholders and NGOs. Working Group C Groundwater has produced numerous guidance documents and technical reports that have been endorsed by EU Water Directors to support and enable Member States to implement the directives. All the documents are published by the EC. Access is available via the following link: http://ec.europa.eu/environment/water/water-framework/groundwater/activities.htm Having addressed implementations issues during the 1st river basin planning cycle, WG C Groundwater is currently focussing on the following issues: groundwater dependent ecosystems, and climate change and groundwater. In the future, the outcome and recommendations of the "Blueprint" - to safeguard Europe's water resources - which was recently published by the EC will be of utmost importance in setting the agenda for the group. Most likely this will include water pricing, water demand management and water abstraction. Complementory to the particular working groups, a Science Policy Interface (SPI) activity has been established. Its purpose is

  17. Current activities in the interactive joint research at Tohoku University. Advanced evaluation of radiation effects on fusion materials

    International Research Center for Nuclear Materials Science of the Institute for Materials Research, Tohoku University (hereafter the 'Center') was founded in 1969 and has been playing a vital role as the joint-use research center in Japan to assess the dynamic and static effects of neutron irradiation on the physical and mechanical properties of a variety of structural and functional materials through the use of nuclear reactors in Japan and overseas. The Center is now also open to researchers overseas. As a new initiative, the Center started an interactive joint research scheme on nuclear fusion reactor engineering with the NIFS in fiscal 2010. The interactive joint research aims at pioneering inter-disciplinary fields that connect neutron reactor engineering with other nuclear fusion sciences, and at conducting activities primarily on the key research subjects through inter-research-center collaboration. For this, a TDS (Thermal Desorption Spectrometer) with an ion gun (IG-TDS) has been installed in the radiation controlled area at the Center. Development of a compact divertor plasma simulator (C-DPS) system that will be integrated with the IG-TDS apparatus is in progress. It is prospected that the Center could play a leading role in international collaborative studies of neutron irradiation effects on plasma material interaction, along with other major research institutes over the world.

  18. Report of fiscal 1999 basic survey for joint implementation, etc. Feasibility study on energy conservation and reduction of CO2 emission at Omsk Refinery

    NONE

    2000-03-01

    This paper explains fiscal 1999 survey on energy conservation and reduction of CO2 at Omsk Refinery in the Russian Federation for the purpose of making the project tied to the COP3 joint implementation. This refinery is the largest class refinery in Russia having a capacity of 600,000 BPSD. The atmospheric distillation unit AVT-10, which emits 470,000 t-CO2/year, was selected for the object of the survey. As the modification plans, optimization of process system, modification of waste heat boiler and installation of new furnaces were considered. The plans 1, 2 are possible due to their low investment costs. The plan 3 to install new furnaces is able to reduce the large volume of CO2 emission though its investment cost is higher. For each modification plan, estimation was made for the investment cost, the benefit by energy saving and the volume of reduction of CO2 emission. The results for each of the plans 1, 2 and 3 were 907x10{sup 3}, 3,377x10{sup 3}, 50,400x10{sup 3} in US$; 535x10{sup 3}, 928x10{sup 3}, 1,407x10{sup 3} in US$; and 36.1x10{sup 3}, 68.2x10{sup 3}, 86.6x10{sup 3} tons/year. The Russian side showed their satisfaction of the results and keen interest in the energy saving effect. For the purpose of realizing this plan, financial assistance and technological cooperation are essential. Russia shows their great expectations for the Japanese government. (NEDO)

    We describe an implementation of the protocol of Damgård, Pastro, Smart and Zakarias (SPDZ/Speedz) for multi-party computation in the presence of a dishonest majority of active adversaries. We present a number of modifications to the protocol; the first reduces the security to covert security, but...... implementation techniques, which are distinct from prior MPC work in this area due to the use of MACs within the SPDZ protocol. We then examine two implementation choices for the finite fields; one based on finite fields of size 28 and one based on embedding the AES field into a larger finite field of size 240...

  20. Application of Computational Lower Extremity Model to Investigate Different Muscle Activities and Joint Force Patterns in Knee Osteoarthritis Patients during Walking

    2013-01-01

    Full Text Available Many experimental and computational studies have reported that osteoarthritis in the knee joint affects knee biomechanics, including joint kinematics, joint contact forces, and muscle activities, due to functional restriction and disability. In this study, differences in muscle activities and joint force patterns between knee osteoarthritis (OA patients and normal subjects during walking were investigated using the inverse dynamic analysis with a lower extremity musculoskeletal model. Extensor/flexor muscle activations and torque ratios and the joint contact forces were compared between the OA and normal groups. The OA patients had higher extensor muscle forces and lateral component of the knee joint force than normal subjects as well as force and torque ratios of extensor and flexor muscles, while the other parameters had little differences. The results explained that OA patients increased the level of antagonistic cocontraction and the adduction moment on the knee joint. The presented findings and technologies provide insight into biomechanical changes in OA patients and can also be used to evaluate the postoperative functional outcomes of the OA treatments.

    Cross-sectoral assessment of health risks arising or existing at the human-animal interface is crucial to identifying and implementing effective national disease control measures. This requires availability of information from 4 functional information 'streams' - epidemiological, laboratory, animal, and human health. The Food and Agriculture Organization of the United Nations (FAO)/ World Organisation for Animal Health (OIE)/ World Health Organization (WHO) Four-Way Linking (4WL) project promotes the establishing of a national-level joint framework for data sharing, risk assessment, and risk communication, in order to both improve communications within and among governmental public health and animal health influenza laboratories, epidemiology offices, national partners, with the aim of strengthening the national capacity to detect, report and assess risks arising from emerging influenza viruses. The project is currently being implemented in countries where H5N1 avian influenza is endemic and where human cases have been reported. The project is comprised of two main activities at country level: a 'review mission', which is the project launch in the country and has the objective to assess the existing situation; and a 'scenario based workshop', with the scope to bring together key national partners and build relationships among people working in the 4 information streams and to improve understanding of national strengths and gaps. During the workshop the delegates engaged in interactive sessions on basic risk assessment and devoted to specify the needs and roles of the 4 different streams. The participants work through a mock influenza outbreak scenario, which practically illustrates how risk assessment and communication of an emergency at the animal-human interface is more effective when there is linking of the 4 streams, collaboration, communication, and coordinated action. In 2010, Egypt was the first country where the project was successfully implemented

  6. Fast joint detection-estimation of evoked brain activity in event-related fMRI using a variational approach

    In standard within-subject analyses of event-related functional magnetic resonance imaging (fMRI) data, two steps are usually performed separately: detection of brain activity and estimation of the hemodynamic response. Because these two steps are inherently linked, we adopt the so-called region-based joint detection-estimation (JDE) framework that addresses this joint issue using a multivariate inference for detection and estimation. JDE is built by making use of a regional bilinear generative model of the BOLD response and constraining the parameter estimation by physiological priors using temporal and spatial information in a Markovian model. In contrast to previous works that use Markov Chain Monte Carlo (MCMC) techniques to sample the resulting intractable posterior distribution, we recast the JDE into a missing data framework and derive a variational expectation-maximization (VEM) algorithm for its inference. A variational approximation is used to approximate the Markovian model in the unsupervised spatially adaptive JDE inference, which allows automatic fine-tuning of spatial regularization parameters. It provides a new algorithm that exhibits interesting properties in terms of estimation error and computational cost compared to the previously used MCMC-based approach. Experiments on artificial and real data show that VEM-JDE is robust to model mis-specification and provides computational gain while maintaining good performance in terms of activation detection and hemodynamic shape recovery.

  8. Joint analysis of infrasound and seismic signals by cross wavelet transform: detection of Mt. Etna explosive activity

    A. Cannata

    2013-06-01

    Full Text Available The prompt detection of explosive volcanic activity is crucial since this kind of activity can release copious amounts of volcanic ash and gases into the atmosphere, causing severe dangers to aviation. In this work, we show how the joint analysis of seismic and infrasonic data by wavelet transform coherence (WTC can be useful to detect explosive activity, significantly enhancing its recognition that is normally done by video cameras and thermal sensors. Indeed, the efficiency of these sensors can be reduced (or inhibited in the case of poor visibility due to clouds or gas plumes. In particular, we calculated the root mean square (RMS of seismic and infrasonic signals recorded at Mt. Etna during 2011. This interval was characterised by several episodes of lava fountains, accompanied by lava effusion, and minor strombolian activities. WTC analysis showed significantly high values of coherence between seismic and infrasonic RMS during explosive activity, with infrasonic and seismic series in phase with each other, hence proving to be sensitive to both weak and strong explosive activity. The WTC capability of automatically detecting explosive activity was compared with the potential of detection methods based on fixed thresholds of seismic and infrasonic RMS. Finally, we also calculated the cross correlation function between seismic and infrasonic signals, which showed that the wave types causing such seismo-acoustic relationship are mainly incident seismic and infrasonic waves, likely with a common source.

  9. Effects of nano-particles strengthening activating flux on the microstructures and mechanical properties of TIG welded AZ31 magnesium alloy joints

    Highlights: • Increased nano-particles strengthening activating flux degraded TIGed seams. • The reaction between SiC particles and Mg alloy produced Al4C3 and Mg2Si phases. • Al4C3 and SiC particles promoted the nucleation and suppressed the growth of α-Mg. • Refined α-Mg grains, precipitated phase and SiC particles enhanced TIGed joints. - Abstract: In this paper, AZ31 magnesium alloy joints were processed by nano-particles strengthening activating flux tungsten inert gas (NSA-TIG) welding, which was achieved by the mixed TiO2 and nano-SiC particles coated on the samples before welding tests. The macro/micro structural observation and mechanical properties evaluation of the welding joints were conducted by using optical microscope, scanning electron microscope, energy dispersive X-ray spectroscopy, X-ray diffraction and tension and microhardness tests. The results showed that nano-particles strengthening activating flux effective improved the microstructure, microhardness in fusion zone, ultimate tensile strength of the TIG welding joints. In addition, the chemical reaction between part of SiC particles and AZ31 magnesium alloy produced Al4C3 and Mg2Si in the joints. The Al4C3 performed as nucleating agents for α-Mg and the dispersed Mg2Si and SiC particles enhanced the mechanical properties of the NSA-TIG welding joints. However, large heat input induced by the increase of the surface coating density of the nano-particles strengthening activating flux, increased the α-Mg grain sizes and weakened the mechanical properties of the welded joints. Therefore, the grain size of α-Mg, distribution of β-Mg17Al12, Mg2Si and SiC particles together influenced the evolution of the mechanical properties of the NSA-TIG welded AZ31 magnesium alloy joints

    2005-01-01

    Background The urokinase plasminogen activator system is believed to play an important role in degradation of the extracellular matrix associated with cartilage and bone destruction; however its precise roles in temporomandibular disorders have not yet been clarified. The aims of this study were to investigate the gene expression of fibrinolytic factors urokinase plasminogen activator (uPA) and plasminogen activator inhibitor-1 (PAI-1) in the articular cartilage of rabbit temporomandibular joint (TMJ) with disc displacement (DD) and to probe the relationship between fibrinolytic activity and cartilage remodeling. Methods Disc displacement of right joints was performed in 36 of 78 rabbits under investigation. The animals were sacrificed at 4 days and 1, 2, 4, 8 and 12 weeks after surgery, respectively. The right joints of these animals were harvested and processed for the examination of mRNA expression of uPA and PAI-1 in articular cartilage using in situ hybridization techniques. Results The expression of uPA and PAI-1 was co-expressed weakly in the chondrocytes from transitive zone to hypertrophic zone and mineralized zone, while no hybridizing signals were shown in proliferative zone and superficial zone in control rabbits. The most striking was the up-regulation of uPA and PAI-1 mRNA in 4-day rabbits postoperatively at the onset of cartilage degeneration. The strongest hybridizing signals for uPA and PAI-1 were seen in 2-week rabbits postoperatively. After 2 weeks, the expression of uPA and PAI-1 began to decrease and reached nearly normal level at 12 weeks. Conclusions The expression of the uPA/PAI-1 system coincides with the pathological changes in condylar cartilage after DD. The uPA/PAI-1 system may be one of the essential mediators in articular cartilage remodeling.

  15. Creep property measurements of welded joint of reduced-activation ferritic steel by the small-punch creep test

    The small-punch (SP) test and the SP creep test were carried out by using a further miniaturized plate-type specimen (3 mm diameter x 0.25 mm thick). Those tests were applied to the electron-beam welded joint of reduced-activation ferritic steel for evaluating the distribution of high-temperature strength in the joint. The experimental results revealed that the distribution of the maximum load measured by the SP test at 873 K was very similar to that obtained from Vickers hardness, and the fusion zone was relatively devoid of high-temperature ductility. In addition, the ratio of the load of SP creep test to the stress of standard uniaxial creep test was calculated so that both the creep rupture curves were overlapped to convert the results of SP creep test into those of standard test. As a result, the ratio was determined to be 0.43 for the base metal and this load-stress conversion coefficient is in good agreement with that obtained from finite element analysis.

  16. Paying for hospital care: the experience with implementing activity-based funding in five European countries.

    O'Reilly, Jacqueline; Busse, Reinhard; Häkkinen, Unto; Or, Zeynep; Street, Andrew; Wiley, Miriam

    2012-01-01

    Following the US experience, activity-based funding has become the most common mechanism for reimbursing hospitals in Europe. Focusing on five European countries (England, Finland, France, Germany and Ireland), this paper reviews the motivation for introducing activity-based funding, together with the empirical evidence available to assess the impact of implementation. Despite differences in the prevailing approaches to reimbursement, the five countries shared several common objectives, albeit with different emphasis, in moving to activity-based funding during the 1990s and 2000s. These include increasing efficiency, improving quality of care and enhancing transparency. There is substantial cross-country variation in how activity-based funding has been implemented and developed. In Finland and Ireland, for instance, activity-based funding is principally used to determine hospital budgets, whereas the models adopted in the other three countries are more similar to the US approach. Assessing the impact of activity-based funding is complicated by a shortage of rigorous empirical evaluations. What evidence is currently available, though, suggests that the introduction of activity-based funding has been associated with an increase in activity, a decline in length of stay and/or a reduction in the rate of growth in hospital expenditure in most of the countries under consideration.

  17. Joint FAO/WHO/IOC activities to provide scientific advice on marine biotoxins (research report)

    The Joint FAO/WHO/IOC ad hoc Expert Consultation on Biotoxins in Molluscan Bivalves performed risk assessments for a number of biotoxins present in bivalve molluscs. For performing risk assessments, the Expert Consultation categorized the biotoxins into eight distinct groups based on chemical structure. The Expert Consultation established LOAELs for the azaspiracid (AZA), okadaic acid (OA), saxitoxin (STX), and domoic acid (DA) toxin groups. The derived provisional acute RfDs for the AZA, OA, STX, and DA toxin groups were 0.04 μg/kg bw, 0.33 μg/kg bw, 0.7 μg/kg bw, and 100 μg/kg bw, respectively. For the yessotoxin (YTX) group, a NOAEL was established, based on animal studies. Applying a safety factor of 100, a provisional acute RfD of 50 μg/kg bw was suggested for the YTX group. The Expert Consultation considered that the database for cyclic imines, brevetoxins, and pectenotoxins was insufficient to establish provisional acute RfDs for these three toxin groups

  1. Wear testing of moderate activities of daily living using in vivo measured knee joint loading.

    Jörn Reinders

    Full Text Available Resumption of daily living activities is a basic expectation for patients provided with total knee replacements. However, there is a lack of knowledge regarding the impact of different activities on the wear performance. In this study the wear performance under application of different daily activities has been analyzed. In vivo load data for walking, walking downstairs/upstairs, sitting down/standing up, and cycling (50 W & 120 W has been standardized for wear testing. Wear testing of each activity was carried out on a knee wear simulator. Additionally, ISO walking was tested for reasons of comparison. Wear was assessed gravimetrically and wear particles were analyzed. In vivo walking produced the highest overall wear rates, which were determined to be three times higher than ISO walking. Moderate wear rates were determined for walking upstairs and downstairs. Low wear rates were determined for standing up/sitting down and cycling at power levels of 50 W and 120 W. The largest wear particles were observed for cycling. Walking based on in vivo data has been shown to be the most wear-relevant activity. Highly demanding activities (stair climbing produced considerably less wear. Taking into account the expected number of loads, low-impact activities like cycling may have a greater impact on articular wear than highly demanding activities.

  3. Correlates of the Intention to Implement a Tailored Physical Activity Intervention: Perceptions of Intermediaries

    Denise Peels

    2014-02-01

    Full Text Available The public health impact of health behaviour interventions is highly dependent on large-scale implementation. Intermediaries—intervention providers—determine to a large extent whether an intervention reaches the target population, and hence its impact on public health. A cross-sectional study was performed to identify the correlates of intermediaries’ intention to implement a computer-tailored physical activity intervention. According to theory, potential correlates are intervention characteristics, organisational characteristics, socio-political characteristics and intermediary characteristics. This study investigated whether intermediary characteristics mediated the association between the intervention, organisational and socio-political characteristics and intention to implement the intervention. Results showed that intervention characteristics (i.e., observability (B = 0.53; p = 0.006; relative advantage (B = 0.79; p = 0.020; complexity (B = 0.80; p < 0.001; compatibility (B = 0.70; p < 0.001, organisational characteristics (i.e., type of organization (B = 0.38; p = 0.002; perceived task responsibility (B = 0.66; p ≤ 0.001; capacity (B = 0.83; p < 0.001, and the social support received by intermediary organisations (B = 0.81; p < 0.001 were associated with intention to implement the intervention. These factors should thus be targeted by an implementation strategy. Since self-efficacy and social norms perceived by the intermediary organisations partially mediated the effects of other variables on intention to implement the intervention (varying between 29% and 84%, these factors should be targeted to optimise the effectiveness of the implementation strategy.

    2013-01-01

    Physical activity is associated with reduced risk of a number of health outcomes, yet fewer than half of adults in the United States report recommended levels of physical activity. Analyses of structural characteristics of the built environment as correlates of physical activity have yielded mixed results. We examine associations between multiple aspects of urban neighborhood environments and physical activity in order to understand their independent and joint effects, with a focus on the ext...

  6. Active vibration control of Flexible Joint Manipulator using Input Shaping and Adaptive Parameter Auto Disturbance Rejection Controller

    Li, W. P.; Luo, B.; Huang, H.

    2016-02-01

    This paper presents a vibration control strategy for a two-link Flexible Joint Manipulator (FJM) with a Hexapod Active Manipulator (HAM). A dynamic model of the multi-body, rigid-flexible system composed of an FJM, a HAM and a spacecraft was built. A hybrid controller was proposed by combining the Input Shaping (IS) technique with an Adaptive-Parameter Auto Disturbance Rejection Controller (APADRC). The controller was used to suppress the vibration caused by external disturbances and input motions. Parameters of the APADRC were adaptively adjusted to ensure the characteristic of the closed loop system to be a given reference system, even if the configuration of the manipulator significantly changes during motion. Because precise parameters of the flexible manipulator are not required in the IS system, the operation of the controller was sufficiently robust to accommodate uncertainties in system parameters. Simulations results verified the effectiveness of the HAM scheme and controller in the vibration suppression of FJM during operation.

    2014-02-01

    The public health impact of health behaviour interventions is highly dependent on large-scale implementation. Intermediaries-intervention providers-determine to a large extent whether an intervention reaches the target population, and hence its impact on public health. A cross-sectional study was performed to identify the correlates of intermediaries' intention to implement a computer-tailored physical activity intervention. According to theory, potential correlates are intervention characteristics, organisational characteristics, socio-political characteristics and intermediary characteristics. This study investigated whether intermediary characteristics mediated the association between the intervention, organisational and socio-political characteristics and intention to implement the intervention. Results showed that intervention characteristics (i.e., observability (B = 0.53; p = 0.006); relative advantage (B = 0.79; p = 0.020); complexity (B = 0.80; p responsibility (B = 0.66; p ≤ 0.001); capacity (B = 0.83; p social support received by intermediary organisations (B = 0.81; p strategy. Since self-efficacy and social norms perceived by the intermediary organisations partially mediated the effects of other variables on intention to implement the intervention (varying between 29% and 84%), these factors should be targeted to optimise the effectiveness of the implementation strategy.

  8. The Effects of NMDA Antagonists on Neuronal Activity in Cat Spinal Cord Evoked by Acute Inflammation in the Knee Joint.

    Schaible, Hans-Georg; Grubb, Blair D.; Neugebauer, Volker; Oppmann, Maria

    1991-01-01

    In alpha-chloralose-anaesthetized, spinalized cats we examined the effects of NMDA antagonists on the discharges of 71 spinal neurons which had afferent input from the knee joint. These neurons were rendered hyperexcitable by acute arthritis in the knee induced by kaolin and carrageenan. They were located in the deep dorsal and ventral horn and some of them had ascending axons. The N-methyl-d-aspartate (NMDA) antagonists ketamine and d-2-amino-5-phosphonovalerate (AP5), were administered ionophoretically, and ketamine was also administered intravenously. In some of the experiments the antagonists were tested against the agonists NMDA and quisqualate. The effects of the NMDA antagonists consisted of a significant reduction in the resting activity of neurons and/or the responses of the same neurons to mechanical stimulation of the inflamed knee. Intravenous ketamine was most effective in suppressing the resting and mechanically evoked activity in 25 of 26 neurons tested. Ionophoretically applied ketamine had a suppressive effect in 11 of 21 neurons, and AP5 decreased activity in 17 of 24 cells. The reduction in the resting and/or the mechanically evoked discharges was achieved with doses of the antagonists which suppressed the responses to NMDA but not those to quisqualate. These results suggest that NMDA receptors are involved in the enhanced responses and basal activity of spinal neurons induced by inflammation in the periphery. PMID:12106256

  9. Implementation and Analysis of DEVS Activity-Tracking with DEVSimPy

    Santucci J.F.

    2013-01-01

    Full Text Available This paper deals with the implementation of Activity-Tracking (AT paradigm in the DEVSimPy environment. DEVSimPy has been developed at the SPE UMR CNRS6134 (University of Corsica in order to facilitate the modeling and the simulation of discrete-event systems described with the DEVS formalism. The AT paradigm is increasingly being used by DEVS modelers for example to improve structural aspects of models (modeling level or to make simulation more efficient using distributed or parallel algorithm (simulation level. Although DEVSimPy can be used as a software providing some features reusable for the implementation of AT paradigm (simulation profiling or step-by-step simulation, the object oriented way used to develop DEVSimPy makes it a powerful tool to implement AT paradigm in a generic manner. DEVSimPy may be viewed as an experimental framework allowing the implementation of new AT techniques while opening up new perspectives in the field of activity modeling and simulation theory.

  12. Joint effect of organic acids and inorganic salts on cloud droplet activation

    M. Frosch

    2010-07-01

    Full Text Available We have investigated CCN properties of internally mixed particles composed of one organic acid (oxalic acid, succinic acid, adipic acid, citric acid, cis-pinonic acid, or nordic reference fulvic acid and one inorganic salt (sodium chloride or ammonium sulphate. Surface tension and water activity of aqueous model solutions with concentrations relevant for CCN activation were measured using a tensiometer and osmometry, respectively. The measurements were used to calculate Köhler curves, which were compared to measured critical supersaturations of particles with the same chemical compositions, determined with a cloud condensation nucleus counter. Surfactant surface partitioning was not accounted for. For the mixtures containing cis-pinonic acid or fulvic acid, a depression of surface tension was observed, but for the remaining mixtures the effect on surface tension was negligle at concentrations relevant for cloud droplet activation, and water activity was the more significant term in the Köhler equation. The surface tension depression of aqueous solutions containing both organic acid and inorganic salt was approximately the same as or smaller than that of aqueous solutions containing the same mass of the corresponding pure organic acids. Water activity was found to be highly dependent on the type and amount of inorganic salt. Sodium chloride was able to decrease water activity more than ammonium sulphate and both inorganic compounds had a higher effect on water activity than the studied organic acids, and increasing the mass ratio of the inorganic compound led to a decrease in water activity. Water activity measurements were compared to results from the E-AIM model and values estimated from both constant and variable van't Hoff factors to evaluate the performance of these approaches. The correspondence between measuments and estimates was overall good, except for highly concentrated solutions. Critical supersaturations calculated with K

    In this paper, we combine active and passive source P wave seismic data to tomographically image the magmatic system beneath Newberry Volcano, located east of the Cascade arc. By using both travel times from local active sources and delay times from teleseismic earthquakes recorded on closely spaced seismometers (300-800 m), we significantly improve recovery of upper crustal velocity structure (benefit from longer deployment times to also record teleseismic sources.

  15. Environmental activities in uranium mining and milling. A Joint NEA/IAEA report

    This report on 'Environmental Activities in Uranium Mining and Milling' presents an overview of environmental activities related to uranium production. The profile of activities and concerns are based on survey responses from 29 countries and a review of relevant activities of the International Atomic Energy Agency and the OECD Nuclear Energy Agency. It also provides an overview of the reported interests of specialists working in the field, including environmental impact assessment, emissions to air and water, work environment, radiation safety, waste handling and disposal, mine and mill decommissioning and site restoration, and the regulation of these activities. The report reflects the increasing awareness in all countries of the need for environmental protection. For several years large programmes have been underway in several countries to clean up wastes from closed mines and mills. Many of these sites, particularly the older ones, were brought into production, operated and closed when little was known about environmental effects. At the time, little concern was given to the resulting environmental impacts. Currently, planning for and conducting uranium mine closure and mill decommissioning, together with site clean-up and restoration, are of almost universal concern. Mine closure and mill decommissioning activities have been or are being conducted in most of the countries with a history of uranium production. Information about several mine closures and mill decommissioning projects is included in this report

  1. Implementation of local feedback controllers for vibration supression of a truss using active struts

    McClelland, Robert; Lim, Tae W.; Bosse, Albert; Fisher, Shalom

    1996-05-01

    This paper describes the design and implementation of local feedback controllers for active vibration suppression of a laboratory truss referred to as the Naval Research Laboratory (NRL) space truss. The NRL space truss is a 3.7 meter, 12-bay aluminum laboratory truss used as a testbed to explore smart structures technologies for future Navy spacecraft missions. To conduct real-time control and data acquisition for the implementation of controllers, a digital signal processor based system is used. Two piezoceramic active struts are employed in this experimental study. Each strut is instrumented with a force transducer and a displacement sensor. Modal strain energy computed using a refined finite element model was used to select the optimum locations of the two actuators to ensure controllability of the first two structural modes. Two local feedback controllers were designed and implemented, an integral force feedback and an integral plus double-integral force feedback. The controllers were designed independently for each active strut using classical control design techniques applied to an identified model of the system dynamics. System identification results and controller design procedure are described along with closed loop test results. The test results show up to a factor of 1/110 attenuation of the truss tip motion due to sinusoidal resonant input disturbances and up to 100 times increase in damping of the lower frequency modes of the truss.

  2. Improvements in Students' Understanding from Increased Implementation of Active Learning Strategies

    Hayes-Gehrke, Melissa N.; Prather, E. E.; Rudolph, A. L.; Collaboration of Astronomy Teaching Scholars CATS

    2011-01-01

    Many instructors are hesitant to implement active learning strategies in their introductory astronomy classrooms because they are not sure which techniques they should use, how to implement those techniques, and question whether the investment in changing their course will really bring the advertised learning gains. We present an example illustrating how thoughtful and systematic implementation of active learning strategies into a traditionally taught Astro 101 class can translate into significant increases in students' understanding. We detail the journey of one instructor, over several years, as she changes the instruction and design of her course from one that focuses almost exclusively on lecture to a course that provides an integrated use of several active learning techniques such as Lecture-Tutorials and Think-Pair-Share questions. The students in the initial lecture-only course achieved a low normalized gain score of only 0.2 on the Light and Spectroscopy Concept Inventory (LSCI), while the students in the re-designed learner-centered course achieved a significantly better normalized gain of 0.43. This material is based upon work supported by the National Science Foundation under Grant No. 0715517, a CCLI Phase III Grant for the Collaboration of Astronomy Teaching Scholars (CATS), and Grant No. 0847170, a PAARE Grant for the Calfornia-Arizona Minority Partnership for Astronomy Research and Education (CAMPARE).

    2011-01-01

    Background Functional magnetic resonance is a non-invasive method that can examine brain activity and has been widely used in various fields including jaw movement and pain processing. Temporomandibular disorder (TMD) is one of the most frequent facial pain problems. The objective of this study was to investigate the brain activities using functional magnetic resonance imaging (fMRI) during unilateral maximal voluntary clenching tasks in the TMD synovitis patients with biting pain.Methods Fourteen TMD synovitis patients with unilateral biting pain and 14 controls were included in the study.Contralateral biting pain was defined as right molar clenching causing left temporomandibular joint (TMJ) pain. Ipsilateral biting pain was defined as right molar clenching causing right TMJ pain. Symptom Check List-90 (SCL-90) was administered to the patients and controls. Independent sample t-test was used to compare the SCL-90 subscales between the two groups. Unilateral clenching tasks were performed by the patients and controls. Imaging data were analyzed using SPM99.Results Patients were divided into contralateral TMD biting pain group (n=8) and ipsilateral TMD biting pain group (n=6). The SCL-90 subscales were significantly different between the two groups for somatization, depression, anxiety,phobic anxiety, and paranoid ideation. Group analysis of the controls demonstrated brain activations in the inferior frontal gyrus, precentral gyrus, middle frontal gyrus, superior temporal gyrus, and insular. The areas of activation were different between right and left clenching task. In TMJ synovitis patients with contralateral or ipsilateral biting pain, the group analysis showed activations in the inferior frontal gyrus, superior temporal gyrus, medium frontal gyrus, precentral gyrus,and anterior cingulate cortex.Conclusions The inferior frontal gyrus and precentral gyrus play essential roles during the unilateral clenching task.Activation of anterior cingulate cortex in the

    Tang, Yi; Blaabjerg, Frede

    2014-01-01

    Active power decoupling techniques are promising solutions for capacitance reduction in single-phase AC/DC or DC/AC systems. This paper proposes a novel circuit topology which can realize the power decoupling function without adding additional active switches into the circuit. Also, the proposed...... topology does not require additional passive component, e.g. inductors or film capacitors for ripple energy storage because this task can be accomplished by the dc-link capacitors themselves, and therefore its implementation cost can be minimized. Another unique feature of the proposed topology...

  12. Control of Surge in Centrifugal Compressors by Active Magnetic Bearings Theory and Implementation

    Yoon, Se Young; Allaire, Paul E

    2013-01-01

    Control of Surge in Centrifugal Compressors by Active Magnetic Bearings sets out the fundamentals of integrating the active magnetic bearing (AMB) rotor suspension technology in compressor systems, and describes how this relatively new bearing technology can be employed in the active control of compressor surge. The authors provide a self-contained and comprehensive review of rotordynamics and the fundamentals of the AMB technology. The active stabilization of compressor surge employing AMBs in a machine is fully explored, from the modeling of the instability and the design of feedback controllers, to the implementation and experimental testing of the control algorithms in a specially-constructed, industrial-size centrifugal compression system. The results of these tests demonstrate the great potential of the new surge control method developed in this text. This book will be useful for engineers in industries that involve turbocompressors and magnetic bearings, as well as for researchers and graduate students...

  13. Dynamic detection of window starting positions and its implementation within an activity recognition framework.

    Ni, Qin; Patterson, Timothy; Cleland, Ian; Nugent, Chris

    2016-08-01

    Activity recognition is an intrinsic component of many pervasive computing and ambient intelligent solutions. This has been facilitated by an explosion of technological developments in the area of wireless sensor network, wearable and mobile computing. Yet, delivering robust activity recognition, which could be deployed at scale in a real world environment, still remains an active research challenge. Much of the existing literature to date has focused on applying machine learning techniques to pre-segmented data collected in controlled laboratory environments. Whilst this approach can provide valuable ground truth information from which to build recognition models, these techniques often do not function well when implemented in near real time applications. This paper presents the application of a multivariate online change detection algorithm to dynamically detect the starting position of windows for the purposes of activity recognition. PMID:27392647

    2009-01-01

    In 2001, the 77th Texas legislature passed Senate Bill 19 requiring students in publicly funded elementary schools to participate in physical activity and schools to implement a coordinated school health program by September 1, 2007. We report on awareness of and adherence to Senate Bill 19 in a statewide sample of elementary schools and a subsample in two public health regions located along the Texas-Mexico border. Statewide, structured interviews with principals indicated high awareness of Senate Bill 19's requirements, but lower awareness of the need for parental involvement. Only 43% of Texas schools had adopted their coordinated program 1 year or less before the implementation deadline. Principals reported an average of 179 min of physical education per week, higher than the 135-min mandate. Among the subsample border schools, principals' physical activity reports were consistent with teacher records and student reports. Further, direct observation of physical education indicated that 50% of class time was spent in moderate and vigorous physical activity, meeting the level of physical activity intensity recommended by Healthy People 2010. The differences observed by public health regions included: more physical activity minutes in Region 10 (231 min compared to 217 min in Region 11); higher adoption of coordinated school health programs (92% compared to 75%); more district-level school health advisory committees (58% compared to 38%) and school-level school health advisory committees (83% compared to 25%); and a lower prevalence of obesity in 4th grade students (21% compared to 32%). Differences by region suggest that Senate Bill 19 is not being adhered to equally across the state, and some regions may require further support to increase implementation. Results underscore the importance of continued monitoring of enacted legislation, and that legislation for child health that focuses on school programs and policies requires funding and refinement to produce

  16. Implementing Joint TB and HIV Interventions in a Rural District of Malawi: Is There a Role for an International Non-Governmental Organisation?

    Zachariah, R.; Teck, R; Harries, A. D.; Humblet, P

    Full Text Available This study investigated the impact of using joint productive activity on the performance of second language learners in reading comprehension at the basic education level in Nigeria. A sample of forty (40 Junior Secondary II students from Kaduna North and South were used for the study. The study was quasi experimental. Government Junior Secondary School Doka was used as the experimental group while Government Junior Secondary School Makera was used as the control group. Both groups were assessed after six weeks of teaching using two reading comprehension tests. T-test was used to test the hypothesis raised in the study. The findings revealed significant differences in the performance of students taught reading comprehension using joint productive activity. Based on the findings teachers are encouraged to use joint productive activities in teaching reading comprehension. This is a positive deviation from the traditional practice in Nigeria where a teacher is regarded as the sole custodian of knowledge and students are empty tabula rasa who should be passive during class teaching. Teachers need to exploit this new approach by designing teaching comprehension activities that will require second language learners’ collaboration and active participation in accomplishing tasks jointly in class with the teacher.

    The aim of the study was to investigate the predictive value of different reduced joint ultrasound (US) assessments of synovitis and tenosynovitis in relation to unstable remission in a cohort of rheumatoid arthritis (RA) patients on methotrexate therapy. Forty-seven RA patients (38 women, 9 men), being treated with methotrexate (MTX), in clinical remission as judged by their consultant rheumatologist were evaluated for disease activity according to the Disease Activity Score (DAS) 28 at baseline and 6 months. Sustained remission and unstable remission were defined according to the baseline and 6-month DAS28 and changes in RA therapy during the follow-up. Each patient underwent at baseline a B-mode and power Doppler (PD) assessment of 44 joints and 20 tendons/tendon compartments by a rheumatologist blinded to the clinical and laboratory data. B-mode synovial hypertrophy (SH), synovial PD signal, B-mode tenosynovitis, and Doppler tenosynovitis were scored 0-3. The presence and index of synovial PD signal in 44 joints [odds ratio (OR) 8.21 (p = 0.016) and OR 2.20 (p = 0.049), respectively] and in 12 joints [OR 5.82 (p = 0.041) and OR 4.19 (p = 0.020), respectively], the presence of SH in wrist and MCP joints [OR 4.79 (p = 0.045)], and the presence of synovial PD signal in wrist-MCP-ankle-MTP joints [OR 4.62 (p = 0.046)] were predictors of unstable remission. The 12-joint or wrist-hand-ankle-MTP US assessments can predict unstable remission in RA patients in apparent clinical remission being treated with MTX. PMID:26712373

    Users in question-answer sites generate huge amounts of high quality and highly reusable information. This information can be categorized by topics but since users' interests change with time, it's important to uncover the temporal patterns and trends in their activity to detect their current expertize. These temporal variations remained unexplored in question-answer sites while detecting them enables us to improve tasks such as: question routing, expert recommending and community life-cycle ...

    Full Text Available Herein, we investigated the effects of a ballet class on the kinetic profiles of creatine kinase (CK and lactate dehydrogenase (LDH activities, cytokines, complement component 3 (C3, and the concentrations of immunoglobulin (Ig, IgA and IgM, in ballerinas. We also verified neutrophil death and ROS release. Blood samples were taken from 13 dancers before, immediately after, and 18 hours after a ballet class. The ballet class increased the plasma activities of CK-total (2.0-fold immediately after class, while the activities of CK-cardiac muscle (1.0-fold and LDH (3.0-fold were observed to increase 18 hours after the class. Levels of the TNF-α, IL-1β, IgG, and IgA were not affected under the study conditions. The exercise was found to induce neutrophil apoptosis (6.0-fold 18 hours after the ballet class. Additionally, immediately after the ballet class, the neutrophils from the ballerinas were found to be less responsive to PMA stimulus. Conclusion. Ballet class was found to result in inflammation in dancers. The inflammation caused by the ballet class remained for 18 hours after the exercise. These findings are important in preventing the development of chronic lesions that are commonly observed in dancers, such as those with arthritis and synovitis.

  3. Energy use in Kenya: advancement of alternative energy sources to mitigate climate change through Activities Implemented Jointly

    The main energy sources in Kenya are biomass, hydropower and geothermal. The source of biomass fuel includes fuelwood, crop residues and animal waste; woodfuel processed through carbonization; biogas from animal waste processed through fermentation; power alcohol and waste-wood from industries. Woodfuel in 1992 provided about 70% of Kenya`s total energy supply. The annual energy consumption in Kenya is about 7 million tonnes of oil equivalent. The main consumers of energy are domestic household, 60%; transport and manufacturing, 13% each, agriculture, 10%; and commercial sector, 6%. Petroleum fuels account for about 20% of the net energy and meets about 86% of the industrial energy demand. The ability to produce hydropower is sensitive to climate-induced water supply changes as power generation turbines operates within a small range of water level variability. Global warming is likely to increase precipitation in the highlands of Kenya. This is bound to affect the five hydropower generating plants along Tana River which contribute about 78% to the national electricity grid. However, increased exploitation of the geothermal resources at Olkaria, Eburru and Lake Bogoria could alleviate the situation once the targeted output of 1000 MW is achieved. The paper carries out a review of the potential energy sources in the country and proposes a country study on the use of renewable sources of energy particularly among the rural population who currently rely heavily on fuelwood as a source of energy. The paper finally proposes specific projects for the AIJ undertaking. (author)

  4. Implementing active-learning strategies to improve physics learning in Latin America

    Alarcon, Hugo; Zavala, G.; Fernandez, R.; Benegas, J.

    2006-12-01

    It is evident that the most effective active-learning strategies to improve physics learning at the college level have been developed in the United States. Recently, some universities in Latin America have begun adopting such methods as a part of institutional projects, or motivated by national projects led by education authorities. In this work we will present two cases, a large-scale implementation of Tutorials in Introductory Physics (1) in Mexico supported by the institution as a part of a change in its educational model, and a medium-scale implementation of this method in Chile supported by the national government. In both experiences, the professors involved in the educational experience have previously participated in a training workshop that prepared them for implementing this strategy in the classroom. The training workshop, described elsewhere (2), was designed also under active learning premises, so teachers completed the proposed activities in the same way as their students will do. We will present the first results of these two projects. References: (1) McDermott, L. C., Shaffer, P. S., & PER (1998).

  5. Making meaning through joint activity in Computer-Supported Collaborative Learning (CSCL settings: the interplay between content-related and activity-related talk

    Cesar Coll

    2014-10-01

    Full Text Available In the recent literature on CSCL which places the spotlight on participants' talk, there is a clear dichotomy between studies that focus on content-related talk and those that focus on off-topic or activity-related talk. In the approach adopted in this paper, based on the notion of educational influence, the guiding hypothesis is that both forms of talk are closely linked in the collaborative dynamics and that activity-related talk, far from being irrelevant, has an essential role to play in promoting the collaborative construction of knowledge. The paper empirically examines this hypothesis in four online collaborative learning situations. The results show that participants in small group situations requiring the preparation of a written product devote a major part of their discursive activity to negotiating the form of organization of their joint activity and to making sure that all members are familiar with it. In contrast, the technological tools used in the collaborative situation do not seem to have an impact on the relative weight of the type of participants' talk, either content-related or activity-related.

  8. Educational, research and implementation activities in the Department of Atomic Physics at Plovdiv University

    The Department of Atomic Physics at Plovdiv University has 40 year long experience in educating students in Atomic and Subatomic Physics. We aim at making the knowledge gained in nuclear physics part of the culture of our students. At the core of our educational activities lies our long and successful experience in studying the characteristics of atomic nuclei. In cooperation with JINR-Dubna we have studied the nuclei of approximately 40 percent of the periodic table elements. These studies also serve as a basis for the diverse implementation activities of the Department, which have an impressive geographical spread. In recent years our research has been focusing more specifically on radio-ecological issues with the valuable support of the Nuclear Regulatory Agency (NRA). Future more intense support on behalf of NRA's together with more dynamic links with other specialized units, such as the Kozloduy NPP in the first place, would considerably contribute to optimizing the effect of our overall activity.

  9. Implications of the regulatory framework and activities on R and D supporting repository implementation

    In the context of geological disposal, the mission of the Belgian regulatory body is to ensure that the repository is developed, constructed, operated and closed in a safe manner, i.e. people and the environment are protected against the hazards of ionising radiation emitted by the radioactive waste, without imposing undue burdens on future generations. This mission involves several types of activities such as the establishment of regulatory requirements as well as of procedures and conditions for meeting these requirements for the various stages of the licensing process (IAEA, 2011). The roles of the regulatory body also include the oversight of the activities of the organisation in charge of waste disposal and the review of the safety case and of its updates throughout the whole process of developing and implementing the geological disposal programme. In order to fulfil its mission, the Belgian regulatory body (constituted by FANC and Bel V) carries out its own R and D programme. R and D work is essential for regulators as it allows maintaining and improving their scientific and technical skills, contributes to their independence and helps to build public confidence in the regulatory system. This paper gives an overview of the Belgian pre-licensing and licensing process. The paper then discusses the possible implications of the regulatory framework and activities (R and D, safety case reviews and issuance of regulatory advices) on the R and D programme developed by the implementer of a disposal programme.

    Full Text Available The motivation of sports occupies an even more important role than actually performing physical activities. The Ministry of Education of the Slovak Republic ensures the implementation of several compulsory elective sports courses through different stages of educational institutions. We were curious how these courses - especially school in nature - act upon vacations in adulthood. By examining curricular documents and implementing questionnaire methods – applying ,,Vacation practice questionnaire” - we questioned the Hungarian language speakers of southern Slovakia n = 2965. The data were processed using the statistic program SPSS 17. 84.5 % (p < 0.01, of the canvassed took part in school in nature, from which 65,8 % (p < 0.01, rated the time spent there as positive. Amongst the positively valuing 44,2 % indicated the mountains as a favourite and frequently chosen travel destination. 25 % spends more than four hours hiking. We may say that organizing schools in nature has to be considered as an important event (5-7 days, where the students have fun, wherefore they will choose mountains as their travel destination more frequently, which results in higher physical activity. Listed partial discoveries are included in the grant: VEGA no. 1/0376/14 Physical activity intervention for the prevention of health of the population of Slovakia.

    On the basis of Kyoto Protocol-provided flexible measures such as joint implementation and clean development mechanisms, a study is conducted for introducing combined cycle into Konakovo Power Plant of Russia currently equipped with antiquated eight 300MW power plants constructed in the 1960's for which early renovation is necessary. The power station is an important power source connecting to the Moscow-Petersburg main. The gas turbine combined facilities to be newly installed will comprise 250MW-class state-of-the-art gas turbines arranged in four blocks, capable of a total output of 1600MW at a thermal efficiency of 58% (with simultaneous supply of heat). Four units capable of 1200MW out of the existing units will stay in operation for load adjusting. Since the price of power is set low under government control, the accounting capital/internal return rate is as low as 2.3%. The rate recalculated under the financing conditions of special yen credit for environmental protection, however, is as high as 19%, so high as to make the renovation an economically feasible project. It is expected that there will be an annual CO2 reduction of 2.3-million tons or a reduction of 57.50-million tons in 25 years (the life span of the new facilities). The renovation may be a joint implementation project to which both Japan and Russia will attach the highest priority. (NEDO)

    Aerogel and water Cerenkov detectors were employed to tag kaons for a lambda hypernuclear spectroscopic experiment which used the (e,e'K+) reaction in experimental Hall C at Jefferson Lab (JLab E05-115). Fringe fields from the kaon spectrometer magnet yielded ~5 Gauss at the photomultiplier tubes (PMT) for these detectors which could not be easily shielded. As this field results in a lowered kaon detection efficiency, we implemented a bucking coil on each photomultiplier tubes to actively cancel this magnetic field, thus maximizing kaon detection efficiency.

  13. Interlayer design to control interfacial microstructure and improve mechanical properties of active brazed Invar/SiO2–BN joint

    Ag–Cu/Cu/Ag–Cu–Ti composite interlayer was successfully designed to braze Invar alloy and SiO2–BN ceramic. The effect of Cu-foil thickness on the microstructure and mechanical properties of the brazed joints was investigated. The results showed that, compared with single Ag–Cu–Ti brazing foil, the formation of brittle Fe2Ti and Ni3Ti compounds detrimental to the joint strength was greatly inhibited by using composite interlayer. The active Ti atoms in the liquid filler reacted with SiO2–BN ceramic to form a TiN–TiB2 fine-grain layer. The desired interfacial microstructure composed of layered Ag- and Cu-based solid solutions was obtained, which was beneficial for the joint strength. The shear strength of brazed joints was 207% higher than the joints brazed with single Ag–Cu–Ti foil when a 100 μm thick Cu interlayer was used. The inhibition of brittle compounds formation was attributed to the control of reaction sequences during brazing and to the addition of Cu barrier layer

  14. Effect of material flow on joint strength in activation spot joining of Al alloy and steel sheets

    Watanabe, Goro; Yogo, Yasuhiro; Takao, Hisaaki

    2014-08-01

    A new joining method for dissimilar metal sheets was developed where a rotated consumable rod of Al alloy is pressed onto an Al alloy sheet at the part overlapped with a mild steel sheet. The metal flow in the joining region is increased by the through-hole in the Al sheet and consumable Al rod. The rod creates the joint interface and pads out of the thinly joined parts through pressing. This produces a higher joint strength than that of conventional friction stir spot welding. Measurements of the joint interface showed the presence of a 5-10 nm thick amorphous layer consisting of Al and Mg oxides.

    Full Text Available Abstract Background Forming implementation intentions (specifying when, where and how to act has been proposed as a potentially effective and inexpensive intervention, but has mainly been studied in controlled settings for straightforward behaviors. Purpose To examine if forming implementation intentions (II could be used in large-scale, population-based interventions that aim to promote more complex and clinically relevant behavior change, we tested the impact of different II on increasing daily physical activity (PA aimed at weight maintenance among 709 Dutch adults. Methods At T0, participants were randomly allocated to a control group or to form II for 1 a prescribed action (walking, 2 self-selected activities, 3 self-selected activities and repeat making these II two times. All participants were asked to increase PA by at least two hours a week (15–20 minutes per day. Post-tests took place two weeks (response 85%, three months (response 78% and six months (response 79% post-intervention. Results No main effects of II formation on BMI or physical activity were found. Intention to increase physical activity moderated the effects of repeated II, but not of the other II conditions. Forming repeated II had a positive effect on total PA and number of active days for respondents with strong intentions. Conclusion Implementation intention interventions may not yet be ready for implementation on its own for large-scale obesity prevention in the general public. Future research should test strategies for optimal II formation in both initiating and maintaining behavioral change. Trial registration ISRCTN81041724

  17. Depleted Monolithic Active Pixel Sensors (DMAPS) implemented in LF-150 nm CMOS technology

    We present the recent development of Depleted Monolithic Active Pixel Sensors (DMAPS), implemented with an LFoundry (LF) 150 nm CMOS process. MAPS detectors based on an epi-layer have been matured in recent years and have attractive features in terms of reducing material budget and handling cost compared to conventional hybrid pixel detectors. However, the obtained signal is relatively small (∼1000 e−) due to the thin epi-layer, and charge collection time is relatively slow, e.g., in the order of 100 ns, because charges are mainly collected by diffusion. Modern commercial CMOS technology, however, offers advanced process options to overcome such difficulties and enable truly monolithic devices as an alternative to hybrid pixel sensors and charge coupled devices. Unlike in the case of the standard MAPS technologies with epi-layers, the LF process provides a high-resistivity substrate that enables large signal and fast charge collection by drift in a ∼50 μm thick depleted layer. Since this process also enables the use of deep n- and p-wells to isolate the collection electrode from the thin active device layer, PMOS and NMOS transistors are available for the readout electronics in each pixel cell. In order to evaluate the sensor and transistor characteristics, several collection electrodes variants and readout architectures have been implemented. In this report, we focus on its design aspect of the LF-DMAPS prototype chip

    We present the recent development of Depleted Monolithic Active Pixel Sensors (DMAPS), implemented with an LFoundry (LF) 150 nm CMOS process. MAPS detectors based on an epi-layer have been matured in recent years and have attractive features in terms of reducing material budget and handling cost compared to conventional hybrid pixel detectors. However, the obtained signal is relatively small (~1000 e-) due to the thin epi-layer, and charge collection time is relatively slow, e.g., in the order of 100 ns, because charges are mainly collected by diffusion. Modern commercial CMOS technology, however, offers advanced process options to overcome such difficulties and enable truly monolithic devices as an alternative to hybrid pixel sensors and charge coupled devices. Unlike in the case of the standard MAPS technologies with epi-layers, the LF process provides a high-resistivity substrate that enables large signal and fast charge collection by drift in a ~50 μm thick depleted layer. Since this process also enables the use of deep n- and p-wells to isolate the collection electrode from the thin active device layer, PMOS and NMOS transistors are available for the readout electronics in each pixel cell.

    2016-07-01

    We present the recent development of DMAPS (Depleted Monolithic Active Pixel Sensor), implemented with a Toshiba 130 nm CMOS process. Unlike in the case of standard MAPS technologies which are based on an epi-layer, this process provides a high-resistive substrate that enables larger signal and faster charge collection by drift in a 50 - 300 μm thick depleted layer. Since this process also enables the use of deep n-wells to isolate the collection electrodes from the thin active device layer, NMOS and PMOS transistors are available for the readout electronics in each pixel cell. In order to characterize the technology, we implemented a simple three transistor readout with a variety of pixel pitches and input FET sizes. This layout variety gives us a clue on sensor characteristics for future optimization, such as the input detector capacitance or leakage current. In the initial measurement, the radiation spectra were obtained from 55Fe with an energy resolution of 770 eV (FWHM) and 90Sr with the MVP of 4165 e-.

  20. Pelvic belt effects on pelvic morphometry, muscle activity and body balance in patients with sacroiliac joint dysfunction.

    Odette Soisson

    Full Text Available The sacroiliac joint (SIJ is frequently involved in low back and pelvic girdle pain. However, morphometrical and functional characteristics related to SIJ pain are poorly defined. Pelvic belts represent one treatment option, but evidence still lacks as to their pain-reducing effects and the mechanisms involved. Addressing these two issues, this case-controlled study compares morphometric, functional and clinical data in SIJ patients and healthy controls and evaluates the effects of short-term pelvic belt application.Morphometric and functional data pertaining to pelvic belt effects were compared in 17 SIJ patients and 17 controls. Lumbar spine and pelvis morphometries were obtained from 3T magnetic resonance imaging. Functional electromyography data of pelvis and leg muscles and center of pressure excursions were measured in one-leg stance. The numerical rating scale was used to evaluate immediate pain-reducing effects.Pelvic morphometry was largely unaltered in SIJ patients and also by pelvic belt application. The angle of lumbar lateral flexion was significantly larger in SIJ patients without belt application. Muscle activity and center of pressure were unaffected by SIJ pain or by belt application in one-leg stance. Nine of 17 patients reported decreased pain intensities under moderate belt application, four reported no change and four reported increased pain intensity. For the entire population investigated here, this qualitative description was not confirmed on a statistical significant level.Minute changes were observed in the alignment of the lumbar spine in the frontal plane in SIJ patients. The potential pain-decreasing effects of pelvic belts could not be attributed to altered muscle activity, pelvic morphometry or body balance in a static short-term application. Long-term belt effects will therefore be of prospective interest.

  1. Joint association of physical activity/screen time and diet on CVD risk factors in 10-year-old children.

    2012-12-01

    The increasing prevalence of childhood overweight and obesity has been associated with an increased risk for cardiovascular disease (CVD). While several studies examined the effect of single behaviors such as physical activity (PA), sedentary behavior or diet on CVD risk, there is a lack of research on combined associations, specifically in children. Therefore, the purpose of this study was to examine the joint association of PA or screen time (ST) and diet on CVD risk factors in children. PA, STand diet were assessed via questionnaire in 210 fifth grade students (age: 10.6 ± 0.4 years). The healthy eating index (HEI) was subsequently calculated as indicator for diet quality. Height, weight, % body fat, and resting blood pressure were measured according to standard procedures and blood samples obtained via fingerprick were assayed for blood lipids. Total cholesterol HDL ratio (TC:HDL), mean arterial pressure (MAP), and % body fat were used as indicators of CVD risk. 55% of children did not meet current PA recommendations on at least 5 days/week and 70% exceeded current recommendations for ST. Further, only 2.5% possessed a "good" diet (HEI> 80). There was no significant association of PA or STand diet on CVD risk score. Neither TC:HDL, MAP, and % body fat nor the total CVD risk score was significantly correlated with diet, PA, or ST. Children in the high PA group, however, had significantly better diet scores. Despite the fact that self-reported PA, ST, or dietary intake were not directly related to CVD risk in this sample, higher activity levels were associated with a healthier diet and lower ST indicating an overall healthier lifestyle of this subgroup.

  3. Cessation of neutrophil influx in C5a-induced acute experimental arthritis is associated with loss of chemoattractant activity from the joint space

    Neutrophil emigration is a critical component of the inflammatory process and is generally thought to play a role in host defense as well as in the tissue injury that often accompanies inflammation. Most inflammatory reactions exhibit a sequence of emigrating cell types, thus clearly demonstrating that the neutrophil influx eventually ceases and that the neutrophils are then removed from the lesion. It has been our premise that in order to understand the processes that lead to the progressive inflammatory reactions that underly so many disease processes, it is important to determine the mechanism by which the ''normal'' inflammatory response resolves. The purpose of this study was to identify the time of cessation of neutrophil influx in experimental arthritis induced by the injection of C5 fragments (C5f) and to investigate mechanisms underlying the cessation process. The migration of i.v. delivery pulses to inflamed joints was assessed by lavage of the joint space and by external scintigraphy. We found no evidence for the development of inhibitory systems against chemotactic factors or ''desensitization'' of the inflamed site, because a second injection of C5f into joints which had been injected previously with C5f resulted in enhancement rather than inhibition of migration. Neither was evidence found for altered tissue barriers to migration or for desensitization of neutrophils as possible explanations for cessation of influx. The major mechanism appeared to be a loss of chemoattractant activity in the joint space between 2 h and 6 h after C5f injection which was detected by transfer into a fresh joint. Radiolabeled C5a des-Arg had a t1/2 of disappearance from the joint of less than 1 h, which suggested that the transferred chemoattractant must, in part, have been due to the generation of new chemotaxins by C5f injection

  4. Design and Implementation of a Nutrition and Physical Activity Curriculum for Child Care Settings

    Carolyn Dunn, PhD

    2006-03-01

    Full Text Available Background Childhood overweight continues to increase in the United States. Children should begin establishing healthy eating and physical activity behaviors at a young age. Context Many children spend a large part of their day in child care settings, whether in preschools or home day care settings. Child care providers in these settings have an opportunity to establish and reinforce habits that promote good health. However, the providers need training and creative educational materials to teach children about healthy eating and physical activity. Color Me Healthy is an educational program focusing on nutrition and physical activity that was developed for children aged 4 and 5 years by three of the authors (C.D., C.T., and L.P.. Methods In 2001 and 2002, the program was implemented in 47 North Carolina counties and the North Carolina Cherokee reservation. In December 2001, we used an information-dissemination model called Train the Trainer during a session to teach county teams comprising local public health professionals and cooperative extension employees how to teach child care providers in their communities to use the curriculum. The child care providers were then trained between March and August 2002. Follow-up evaluation forms were given to trained child care providers 8 weeks after the training. Consequences Of the providers who completed the evaluations (n = 486, 92.0% indicated that using the Color Me Healthy curriculum increased the physical activity of their students, and 91.8% indicated that it increased the children’s knowledge about movement. In addition, 93.0% of providers also indicated that using Color Me Healthy had increased the children’s knowledge about healthy eating. Interpretation Child care providers need educational materials on healthy eating and physical activity and should be trained to use them. The Train the Trainer model is an effective way to teach public health professionals to train child care providers on

    Full Text Available Studying the issues of implementation of financial support of tour operator activities in the Russian Federation, which have so far impeded the guaranteeing of protection of rights and legitimate interests of Russian tourists at a proper level, allows to formulate practical recommendations and suggestions for improvement of Russian legislation in order to enhance the efficiency of legal regulation of tourism field and protection of rights and legitimate interests of Russian citizens. The article presents a comparative study of the Russian financial guarantee institution and its foreign analogues, defines the causes of emergence of the institution of financial support of tour operator activities in Russian legislation and imposition of a prohibition on tour operator activities. We have come to the conclusion that acknowledgment of financial support of tour operator activities as financial guarantees of tour operator’s liability. Analysis of current Russian legislation allowed to detect its contradictions and develop practical recommendations for improvement of Russian tourism legislation. In particular, it allowed to draw a conclusion of the need to eliminate the non-conformance of standards of article 17.6 of the Federal law NO 132-FZ “On foundations of tourist activity in the Russian Federation” (“Tourist activity law” further on issued on 24.11.1996 to the standards of item 1 of article 48; item 1 of article 53; item 1, item 3 of article 56; article 402 of the Civil code of the Russian Federation (part one; federal law № 51-FZ issued on 30.11.1994 (the Civil code of the Russian Federation.

  6. Preparing for construction and operation of geological repositories - Challenges to the regulator and the implementer. Main findings of a joint RF/IGSC workshop Held in Issy-les-Moulineaux, France. 23-25 January 2012

    A key challenge for some national radioactive waste management programmes and an important learning opportunity for many others will be the licensing of the construction and operation of the first deep geological repositories for high level waste and spent fuel over the next decade. This document describes the main findings of the international workshop on this topic organised jointly by the Regulators' Forum (RF) and the Integration Group for the Safety Case (IGSC) of the NEA/RWMC. The main objective of the workshop was to identify, and share experience on, the challenges that implementers and regulators are facing or will face when preparing for the license for the implementation of a deep geological repository. Additional objectives were to: listen to viewpoints from representatives of governments and local communities, increase awareness of the actual challenges/issues and of the state of the art in dealing with them, identify areas of commonalities and differences amongst parties and explanation of the different views, create a record of the current thinking, inform future work at the international level. The first session introduced the workshop, its aims, the challenges to be faced and the expected achievements. The following sessions were divided into three parts: presentations, in plenary, of national case studies from both the regulators' and implementers' viewpoints and focusing on issues and practices in construction and operation of geological disposal facilities; round table discussions led by a moderator and recorded by a round-table spoke-person; presentation by spoke-persons in plenary followed by wrap up of the session by the session Rapporteur. The main findings concerned licensing regimes, challenges for construction (implementer), challenges for construction (regulator), challenges for operation (implementer and regulator), optimisation

  7. Towards developing a customer relationship management (CRM) strategy for supporting pre-implementation activities in business

    Khashab, Basel; Gulliver, Stephen; Michell, Vaughan

    2013-01-01

    Effectively preparing and planning for Customer Relationship Management (CRM) strategy is critical to CRM implementation success. A lack of a common and systematic way to implement CRM means that focus must be placed on the pre-implementation stage to ensure chance of success. Although existing CRM implementation approaches evidence the need to concentrate mostly on the pre-implementation stage, they fail to address some key issues, which raises the need for a generic framework that address ...

  8. Potential of Active-Steering Bogie for Reducing Lateral Axle Load Caused at Worn Welded Joints of Outer Rail in Curved Track

    Iizuka, Tatsuya; Tanifuji, Katsuya; Soma, Hitoshi

    This paper deals with the potential of an active-steering bogie to reduce the large lateral axle load that arises at worn welded joints of the outer rail in a curved track when high-speed trains pass. The shape of the worn joint, called lateral ‘angular bent’, is modeled on the basis of the measured irregularity shape of actual joints. Then, numerical simulation of running on a curved track is carried out for a two-axle bogie vehicle to compare an active-steering bogie and a conventional nonsteering bogie. The behavior of the vehicle negotiating the curve is evaluated from the viewpoints of decreasing the peak value of lateral axle load within the allowance limit and maintaining the running stability. To satisfy the requirements, wheelset-supporting parameters and feedback gains for active-steering are optimized on a curved section of 400 m radius by the Genetic Algorithm. On the basis of the optimized wheelset-supporting parameter values, additional sets of feedback gains, which are adjusted for the curves of different radii, are proposed. The numerical simulation shows that the operation speed of a vehicle with active-steering bogies having the optimized parameter values has the potential to be raised to the possible speed for tilting trains while satisfying the criterion of riding comfort.

  9. Joint molecule resolution requires the redundant activities of MUS-81 and XPF-1 during Caenorhabditis elegans meiosis.

    Nigel J O'Neil

    Full Text Available The generation and resolution of joint molecule recombination intermediates is required to ensure bipolar chromosome segregation during meiosis. During wild type meiosis in Caenorhabditis elegans, SPO-11-generated double stranded breaks are resolved to generate a single crossover per bivalent and the remaining recombination intermediates are resolved as noncrossovers. We discovered that early recombination intermediates are limited by the C. elegans BLM ortholog, HIM-6, and in the absence of HIM-6 by the structure specific endonuclease MUS-81. In the absence of both MUS-81 and HIM-6, recombination intermediates persist, leading to chromosome breakage at diakinesis and inviable embryos. MUS-81 has an additional role in resolving late recombination intermediates in C. elegans. mus-81 mutants exhibited reduced crossover recombination frequencies suggesting that MUS-81 is required to generate a subset of meiotic crossovers. Similarly, the Mus81-related endonuclease XPF-1 is also required for a subset of meiotic crossovers. Although C. elegans gen-1 mutants have no detectable meiotic defect either alone or in combination with him-6, mus-81 or xpf-1 mutations, mus-81;xpf-1 double mutants are synthetic lethal. While mus-81;xpf-1 double mutants are proficient for the processing of early recombination intermediates, they exhibit defects in the post-pachytene chromosome reorganization and the asymmetric disassembly of the synaptonemal complex, presumably triggered by crossovers or crossover precursors. Consistent with a defect in resolving late recombination intermediates, mus-81; xpf-1 diakinetic bivalents are aberrant with fine DNA bridges visible between two distinct DAPI staining bodies. We were able to suppress the aberrant bivalent phenotype by microinjection of activated human GEN1 protein, which can cleave Holliday junctions, suggesting that the DNA bridges in mus-81; xpf-1 diakinetic oocytes are unresolved Holliday junctions. We propose that the

    The very foundation of cooperation between the United States (US) and Russia (former Soviet Union) in space exploration is a direct result of the mutual desire for scientific understanding and the creation of a collaborative mechanism—the Joint Working Group (JWG) on Space Biology and Medicine. From the dawn of the space age, it has been the quest of humankind to understand its place in the universe. While nations can and do solve problems independently, it takes nations, working together, to accomplish great things. The formation of the JWG provided an opportunity for the opening of a series of productive relationships between the superpowers, the US and the Union of Soviet Socialist Republics (USSR); and served as a justification for continued relationship for medical assistance in spaceflight, and to showcase Earth benefits from space medicine research. This relationship has been played out on an international scale with the construction and operation of the International Space Station. The fundamental reason for this successful endeavor is a direct result of the spirit and perseverance of the men and women who have worked diligently side-by-side to promote science and move our understanding of space forward. This manuscript provides a historical perspective of the JWG; how it came about; its evolution; what it accomplished; and what impact it has had and continues to have in the 21st century with regard to human spaceflight and space life sciences research. It captures the spirit of this group, which has been in continuous existence for over 40 years, and provides a never before reported summary of its activities.

  11. Process evaluation methods, implementation fidelity results and relationship to physical activity and healthy eating in the Faith, Activity, and Nutrition (FAN) study.

    Saunders, Ruth P; Wilcox, Sara; Baruth, Meghan; Dowda, Marsha

    2014-04-01

    Faith, Activity and Nutrition (FAN), a community-based participatory research project in African American churches, aimed to increase congregant physical activity and healthy eating. The Health-Promoting Church framework, developed collaboratively with faith-based partners, guided the intervention and a comprehensive process evaluation. The Health-Promoting Church components related to healthy eating and physical activity were getting the message out, opportunities, pastor support, and organizational policy. There was no evidence for sequential mediation for any of the healthy eating components. These results illustrate the complexity of systems change within organizational settings and the importance of conducting process evaluation. The FAN intervention resulted in increased implementation for all physical activity and most healthy eating components. Mediation analyses revealed no direct association between implementation and increased physical activity; rather, sequential mediation analysis showed that implementation of physical activity messages was associated with improved self-efficacy at the church level, which was associated with increased physical activity.

  12. Design and implementation of an active rectangular aerostatic thrust bearing stage with electromagnetic actuators

    MAO JunHong; LI LiChuan

    2009-01-01

    The design and implementation of an active rectangular aerostaUc thrust bearing stage with electro-magnetic actuators are presented. The stage is fundamentally precise and simple since the out-of-plane degree-of-freedoms (DOF) of a thrust air bearing are closed-loop controlled by electromagnetic actua-tors. The design is one-moving-part with mechanical symmetry, and a commercially available air bear-ing is rigidly attached to the table. The actuators are four independent coils mounted to the guiding surface of the table with iron cores, which are directly machined on the table. A bench level prototype system is developed and out-of-plane axes decoupled models of the system are derived. A control al-gorithm synthesized by arbitrarily placing closed-loop poles according to the model with air bearing dynamics neglected is implemented by C programming language running on the DOS platform. The stage is capable of vertical direction precision micro-positioning and guiding 3-DOF plane motions without limiting the working range of plane motions. Positioning accuracy of the stage no longer de-pends upon design and manufacturing of an air bearing, while passive preload of the stage for a flat film aerostatic thrust bearing is eliminated.

  13. Implementation of interprofessional learning activities in a professional practicum: The emerging role of technology.

    Brault, Isabelle; Therriault, Pierre-Yves; St-Denis, Louise; Lebel, Paule

    2015-01-01

    To prepare future healthcare professionals to collaborate effectively, many universities have developed interprofessional education programs (IPE). Till date, these programs have been mostly courses or clinical simulation experiences. Few attempts have been made to pursue IPE in healthcare clinical settings. This article presents the results of a pilot project in which interprofessional learning activities (ILAs) were implemented during students' professional practicum and discusses the actual and potential use of informatics in the ILA implementation. We conducted a pilot study in four healthcare settings. Our analysis is based on focus group interviews with trainees, clinical supervisors, ILA coordinators, and education managers. Overall, ILAs led to better clarification of roles and understanding of each professional's specific expertise. Informatics was helpful for developing a common language about IPE between trainees and healthcare professionals; opportunities for future application of informatics were noted. Our results support the relevance of ILAs and the value of promoting professional exchanges between students of different professions, both in academia and in the clinical setting. Informatics appears to offer opportunities for networking among students from different professions and for team members' professional development. The use of technology facilitated communication among the participants. PMID:25955721

  14. An fMRI study of joint action – varying levels of cooperation correlates with activity in sensorimotor control, but not mentalization, networks

    Thierry Chaminade

    2012-06-01

    Full Text Available As social agents, humans continuously interact with with the people around them. Here, motor cooperation was investigated by designing a situation in which pairs of participants, one being scanned with fMRI, controlled jointly a visually presented object with joystick movements. The object oscillated dynamically along two dimensions, shades of pink and width of gratings, corresponding to the two cardinal directions of joystick movements. While the overall control of each participant on the object was kept constant, the amount of cooperation along the two dimensions varied along four levels, from no (each participant controlled exclusively one dimension to full (each participant controlled half of each dimension cooperation. Increasing cooperation correlated with BOLD signal in the left parietal operculum and anterior cingulate cortex, while decreasing cooperation correlated with activity in the right inferior frontal and superior temporal gyri, in the intraparietal sulci and inferior temporal gyrii bilaterally, and in the dorsomedial prefrontal cortex. As joint control improved with the level of cooperation, we assessed the brain responses correlating with joint performance, and found that activity in most of the areas associated with levels of cooperation also correlated with the joint performance. The only brain area found exclusively in the negative correlation with cooperation was within the posterior region of the rostral medial frontal cortex, involved in the monitoring of action outcome. We therefore propose that this region responds to the predictability of visual feedback given the motor commands, which is maximal when participants do not cooperate as they fully control one dimension. Our results therefore indicate that, in the current experimental paradigm, the level of cooperation affects sensorimotor processing, but not mentalizing. Altogether, humans do not need to have access to others’ intentional states to cooperate on a joint

  16. Implementing the strategy of multileveled PI activities to promote rapid nuclear power development

    The first two decades of the 21st century is the golden time for nuclear power development in China. According to the nuclear power development program laid down by the State Development and Reform Commission, nearly 30 units of 1000MW will be built in the next 15 years, so as to meet fastgrowing energy demand, to optimize energy mix and to alleviate environmental pollution. Under such a new situation, based on the public information practice and experience during the construction and operation of Qinshan Nuclear Power Complex where the first commercial NPP originated in the Mainland of China, this paper emphasizes on the necessity of establishment of an active and open strategy of multileveled nuclear energy public information activities and implementation of the strategy with adoption of various forms of nuclear energy popularization means, including seminars, contests, exhibitions, site tour to nuclear power plants, reports by mass media, hosting questions-answering dialogue by experts via Internet, TV and radio programs, newspapers and journals , etc.. Thus through the nuclear energy public information activity the recognition and confidence of the public, especially the local community and the public in vicinity of new nuclear power sites on the nuclear energy can be enhanced, and the nuclear power program can gain their support. Furthermore, the fine social environment for nuclear power development can be fostered. (authors)

  18. Implementation and Utilisation of Activity-Based-Costing: A Danish Perspective

    Nielsen, Steen; Sørensen, René; Jakobsen, Morten;

    2004-01-01

    The Activity-Based Costing (ABC) has achieved great attention in Denmark by now but no large survey exists concerning motives for implementing ABC in Denmark. Characteristic of the present situation is the lack of information concerning the current state of cost ac-counting practice. This paper...... reviews the result of a questionnaire survey of 90 respon-dents from Danish medium-size and large manufacturing companies. The analysis is based on a LISREL (LInear Structural RELation) model. The objective of the LISREL model is to test covariance-structures among latent and manifest variables where...... latent variables cannot be directly measured. Different variables related to relevance, size of the company, and sources for knowledge of ABC are tested. The findings show that a relatively large number of companies now have adopted ABC as a new cost management technique. The results also show...

  20. A Color LED Driver Implemented by the Active Clamp Forward Converter

    C. H. Chang

    2013-03-01

    Full Text Available Because light emitting diodes (LEDs have the advantages of dc working voltage, high luminescent efficiency, shortignition time, high reliability and pollution free, they have substituted for incandescent bulbs and fluorescent lampsgradually. In order to simplify circuit complexity, an active clamp forward converter with the sequential color display(SCD control is proposed to drive red, green and blue (RGB LED arrays. The proposed converter has zero-voltageswitching (ZVS operations of both the main switch and the auxiliary switch, resulting in high system efficiency. DrivingRGB LED arrays sequentially by one converter can save components and reduce cost significantly. Additionally, thepulse-width modulation (PWM control is applied to achieve a large chromaticity variation. The circuit operations areanalyzed in detail and the circuit parameters are designed based on the practical considerations. Finally, an illustrativeexample is implemented to demonstrate the feasibility and validity of the proposed LED driver.

  1. Restoration of active gully systems following the implementation of bioengineering techniques.

    Borja, Pablo; Vanacker, Veerle; Govers, Gerard

    2015-04-01

    Intensive land use in the central parts of the Andean basin has led to widespread land degradation. The formation of badlands dates back from the 1950s and 1960s. Several studies indicate that human activities have accelerated mountain erosion rates by up to 100 times. In this study, we have evaluated the effects of bio-engineering works aiming to stabilize degraded catchments. Five micro-catchments (0.2 up to 5 ha) have been selected within a 3 km2 area in the lower part of the Loreto catchment (Southern Ecuadorian Andes). The five micro-catchments differ in vegetation cover and implementation of bio-engineering works. The experimental design consisted of three micro-catchments: (1) DI with conservation works, (2) DF with reforestation by Eucalyptus sp and (3) DT with no conservation works. Two micro-catchments have been monitored in an agricultural area: with (AI) and without (AT) bio-engineering works in the active gullies. Small checkdams were constructed in the gully floors of two of the micro-catchments in the badland area (DI) and the agricultural area (AI). The checkdams are made of wood and tires. Water flow has been measured in every micro-catchment, while sediment traps were constructed to monitor sediment transport. Results show that bio-engineering techniques are effective to stabilize active gullies. Deposition of sediments in manmade dams is strongly dependent on previous rainfall events, as well as gully channel slope, and its vegetation cover. From the experimental data, an I30 max threshold value was determined. Above this threshold value, all micro-catchments are actively contributing sediment to the main river system. The checkdams built with wood and tires have an efficiency of 70%, and were shown to be very effective to stabilize active gullies in bad lands through significant reduction (about 62%) of the amount of sediment exported from the micro-catchments. Key words: degraded soils, erosion, sediment, restoration, reforestation

    2011-08-01

    The program "active health promotion in old age" focuses on persons aged 60 years and older who are not in need of care and are living independently without cognitive impairment. The objective of the intervention is to improve physical activity, healthy nutrition, and the integration of older people into network structures. The intervention was successfully conducted in an urban setting and has now been transferred to a rural area in southwestern Germany (Baden-Wuerttemberg). It was offered to statutory health insured people of Baden-Wuerttemberg within an integrated care program and was free of charge. This article reports the results of the process evaluation. For data collection, participants were interviewed using a standardized questionnaire. Semistructured interviews were conducted with the intervention team and involved general practitioners. In addition, secondary data were used to analyze selection bias between participants and nonparticipants. Although the rural area has a major impact on recruitment, access, and factors of implementation, results demonstrate that the intervention is highly accepted by participants. Moreover, structural conditions (e.g., fitness clubs, exercise classes) are essential for a successful transfer. PMID:21800241

  9. Web Services Implementations at Land Process and Goddard Earth Sciences Distributed Active Archive Centers

    Cole, M.; Bambacus, M.; Lynnes, C.; Sauer, B.; Falke, S.; Yang, W.

    2007-12-01

    NASA's vast array of scientific data within its Distributed Active Archive Centers (DAACs) is especially valuable to both traditional research scientists as well as the emerging market of Earth Science Information Partners. For example, the air quality science and management communities are increasingly using satellite derived observations in their analyses and decision making. The Air Quality Cluster in the Federation of Earth Science Information Partners (ESIP) uses web infrastructures of interoperability, or Service Oriented Architecture (SOA), to extend data exploration, use, and analysis and provides a user environment for DAAC products. In an effort to continually offer these NASA data to the broadest research community audience, and reusing emerging technologies, both NASA's Goddard Earth Science (GES) and Land Process (LP) DAACs have engaged in a web services pilot project. Through these projects both GES and LP have exposed data through the Open Geospatial Consortiums (OGC) Web Services standards. Reusing several different existing applications and implementation techniques, GES and LP successfully exposed a variety data, through distributed systems to be ingested into multiple end-user systems. The results of this project will enable researchers world wide to access some of NASA's GES & LP DAAC data through OGC protocols. This functionality encourages inter-disciplinary research while increasing data use through advanced technologies. This paper will concentrate on the implementation and use of OGC Web Services, specifically Web Map and Web Coverage Services (WMS, WCS) at GES and LP DAACs, and the value of these services within scientific applications, including integration with the DataFed air quality web infrastructure and in the development of data analysis web applications.

    The above-named effort aims to work out modification plans and to predict their energy saving, energy substituting, and greenhouse gas reduction effects, and thereby to scout out a project which will effectively utilize flexibility-ensuring 'joint implementation' for the attainment of greenhouse gas reduction levels defined at COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change). The results of assessment of this project based on the outcome of the survey show that (1) there is necessity for the project and that the presence of needs to be urgently satisfied is clear, that (2) energy saving, energy substituting, and greenhouse gas reduction effects are proved to exist and that the project is therefore an appropriate candidate for an activity to be implemented jointly, that (3) Russian agencies concerned are strongly interested in the project and that a sufficiently cooperative system will be available toward implementation, and that (4) there is an extremely large room for energy saving in the district heating oriented heat supply business in Russia and that probabilities are quite high that natural gas-fired turbine cogeneration plants capable of improving overall energy efficiency will enjoy extensive diffusion.

  11. Considerations on the implementation and modeling of an active mass driver with electric torsional servomotor

    Ubertini, Filippo; Venanzi, Ilaria; Comanducci, Gabriele

    2015-06-01

    The current trend in full-scale applications of active mass drivers for mitigating buildings' vibrations is to rely on the use of electric servomotors and low friction transmission devices. While similar full-scale applications have been recently documented, there is still the need for deepening the understanding of the behavior of such active mass drivers, especially as it concerns their reliability in the case of extreme loading events. This paper presents some considerations arisen in the physical implementation of a prototype active mass driver system, fabricated by coupling an electric torsional servomotor with a ball screw transmission device, using state-of-the-art electronics and a high speed digital communication protocol between controller and servomotor drive. The prototype actuator is mounted on top of a scaled-down five-story frame structure, subjected to base excitation provided by a sliding table actuated by an electrodynamic shaker. The equations of motion are rigorously derived, at first, by considering the torque of the servomotor as the control input, in agreement with other literature work. Then, they are extended to the case where the servomotor operates under kinematic control, that is, by commanding its angular velocity instead of its torque, including control-structure-interaction effects. Experiments are carried out by employing an inherently stable collocated skyhook control algorithm, proving, on the one hand, the control effectiveness of the device but also revealing, on the other hand, the possibility of closed-loop system instability at high gains. Theoretical interpretation of the results clarifies that the dynamic behavior of the actuator plays a central role in determining its control effectiveness and is responsible for the observed stability issues, operating similarly to time delay effects. Numerical extension to the case of earthquake excitation confirms the control effectiveness of the device and highlights that different

  19. Report on basic survey project for promoting joint implementation in 1999. Feasibility study on energy conservation and reduction of CO2 emission at Balikpapan Refinery

    NONE

    2000-03-01

    With an objective of implementation as the clean development mechanism (CDM), a survey was performed on energy conservation and CO2 reduction at Balikpapan Refinery in Indonesia with respect to reducing emission of greenhouse effect gases. A crude oil atmospheric distillation unit with a capacity of 200,000 BPSD, and a vacuum distillation unit with a capacity of 81,000 BPSD are in operation, which emit carbon dioxide of about 470,000 tons annually from fuels burned and consumed by these units. The result of the survey revealed that there is a room for improvement in heat recovery, and that these units are separated into two groups located far away with each other in distance, resulting in low thermal efficiency and wastes in fuel. Increase in heat recovery should be achieved, and fuel consumption in the heating furnace should be reduced. Energy saving technologies owned by JGC were applied to establish a modification plan. The plan calls for maximum annual reduction of carbon dioxide of about 61,000 tons at a reduction rate of 13%, and maximum annual fuel conservation of 190 times 10{sup 9} kcal at a saving rate of 13%. PERTAMINA also desires the realization thereof if technical and financial assistance is made available. The project has a significance that it would give a great impetus to the entire regions and industries. (NEDO)

  20. Input-output analysis of alternative policies implemented on the energy activities: An application for Catalonia

    The aim of this paper is to analyze the economic impact of alternative policies implemented on the energy activities of the Catalan production system. Specifically, we analyze the effects of a tax on intermediate energy uses, a reduction in intermediate energy demand, and a tax on intermediate uses combined with a reduction in intermediate energy demand. The methodology involves two versions of the input-output price model: a competitive price formulation and a mark-up price formulation. The input-output price framework will make it possible to evaluate how the alternative measures modify production prices, consumption prices, private real income, and intermediate energy uses. The empirical application is for the Catalan economy and uses economic data for the year 2001. The combination of a tax on energy uses and an improvement in the energy efficiency of the production system is a measure that accomplishes both economic and environmental goals, since it has no effects on prices, it has a positive effect on private real income and, finally, energy consumption is considerably reduced.

  4. Implementation of Active Teaching Methods and Emerging Topics in Photogrammetry and Remote Sensing Subjects

    Kosmatin Fras, M.; Grigillo, D.

    2016-06-01

    Fast technological developments in photogrammetry and remote sensing areas demand quick and steady changes in the education programme and its realization. The university teachers and assistants are faced with ensuring the learning materials, data and software for practical lessons, as well as project proposals for student's team work and bachelor or master thesis. In this paper the emerging topics that already have a considerable impact in the practice are treated mostly from the educational aspect. These relatively new topics that are considered in this paper are unmanned aerial systems for spatial data collection, terrestrial and aerial laser scanning, mobile mapping systems, and novelties in satellite remote sensing. The focus is given to practical implementation of these topics into the teaching and learning programme of Geodesy and Geoinformation at the University of Ljubljana, Faculty of Civil and Geodetic Engineering, and experiences gained by the authors so far. Together with the technological advances, the teaching approaches must be modernized as well. Classical approaches of teaching, where a lecturer gives lecture ex cathedra and students are only listeners, are not effective enough. The didactics science of teaching has developed and proved in the practice many useful approaches that can better motivate students for more active learning. We can use different methods of team work like pro et contra debate, buzzing groups, press conference, moderated discussion etc. An experimental study on active teaching methods in the class of students of the Master programme of Geodesy and Geoinformation has been made and the results are presented. After using some new teaching methods in the class, the students were asked to answer two types of a questionnaire. First questionnaire was the standard form developed by Noel Entwistle, an educational psychologist who developed the Approaches to Studying Inventory (ASI) for identifying deep and surface approaches to

  9. The temporomandibular joint

    Whilst the temporomandibular joint is in many ways unique, it is subject to all the diseases and disorders found in joints in other parts of the human skeleton. By far the most common disorder is injury, followed by arthropathy, acute and chronic dislocations, ankylosis, and in rare instances, neoplasms. The diagnosis and management of the temporomandibular joint are the primary responsibility of the oral surgeon. Nevertheless, this anatomical region is an area in which the cooperation of medical and dental disciplines may be required for the satisfactory conclusion of treatment. The more so when the disease process involves either associated psychosomatic illness or malignancy. The mainstay of the diagnosis is a careful radiological examination of the joint. There exists a delicate relationship between the dentition, the muscles of mastication, and the temporomandibular articulation, which is controlled by arthrokinetic reflex activity of the branches of the 5th cranial nerve. Imbalance between one or more of the components of this integrated system frequently leads to disturbances in function. Pain-dysfunction disorders constitute the larger part of temporomandibular joint disturbances generally encountered

    Full Text Available The Master Plan Activity of Serayu River Voyage (SRV for tourism development in Banyumas Regency were expected to be completed within five years from 2008 to 2012, but during the period until 2013, most programs and activities have not been implemented. The results showed that the Master Plan of SRV in the framework of tourism development in Banyumas Regency has not been implemented properly. The cause is the absence of good coordination between agencies, the lack programs and activities integration, supporting documents have not been revised, absence of good socialization, and the lack of private sector contribution. The factors that constrain and support implementation of the Master Plan is described as follows. Supporting factors: competent human resources (implementor already available at the managerial level and have intellectual tourism, it is only need to add personnel in the sector of culture; the availability of adequate budget; institutions that have been effective and efficient; High community response; High commitment of Banyumas Regent and cooperation related parties (stakeholders; and natural conditions of Serayu tend to calm and the river slope condition is small. The constrain factors: regulatory policies; integration of programs and activities; coordination and socialization implied sectoral ego that need to be addressed.

  14. Portal project implementation in Nuclear Malaysia to support knowledge management activities

    In Malaysian Nuclear Agency (Nuclear Malaysia), a portal project initiative was initiated as early as the preparation of its specification in the middle of the year 2005. It took six months project development and implementation to fit into Nuclear Malaysia requirements. The overall project is divided into two types of portal implementation, namely, Internet and Intranet Portal. The main objective of the portal project is to support knowledge management at the organizational level through the simplicity of content management system using web and open source technology. The portal project includes some features of knowledge management system such as online collaboration and communication, knowledge repository and document management. After few months implementation, we found that the number of hits by users in Intranet portal is still small. On the other hand, Internet portal still need to be improved on the design as well as the content. This paper describes Nuclear Malaysia's experience in the development and the implementation of the portal project in terms of the preparation, approaches and problems encountered during the operation and implementation of the project. Several recommendations based on the experience gained toward a successful implementation of the Internet and Intranet Portal is discussed and to be shared for the benefit of other nuclear research institutes

    2014-10-01

    Issuance of national policy guidance is a critical step to ensure quality HIV-TB (human immunodeficiency virus-tuberculosis) coordination and programme implementation. From the database of the Joint United Nations Programme on HIV/AIDS (UNAIDS), we reviewed 62 national HIV and TB guidelines from 23 high-burden countries for recommendations on HIV testing for TB patients, criteria for initiating antiretroviral therapy (ART) and the Three I's for HIV/TB (isoniazid preventive treatment [IPT], intensified TB case finding and TB infection control). We used UNAIDS country-level programme data to determine the status of implementation of existing guidance. Of the 23 countries representing 89% of the global HIV-TB burden, Brazil recommends ART irrespective of CD4 count for all people living with HIV, and four (17%) countries recommend ART at the World Health Organization (WHO) 2013 guidelines level of CD4 count ⩿500 cells/mm(3) for asymptomatic persons. Nineteen (83%) countries are consistent with WHO 2013 guidelines and recommend ART for HIV-positive TB patients irrespective of CD4 count. IPT is recommended by 16 (70%) countries, representing 67% of the HIV-TB burden; 12 recommend symptom-based screening alone for IPT initiation. Guidelines from 15 (65%) countries with 79% of the world's HIV-TB burden include recommendations on HIV testing and counselling for TB patients. Although uptake of ART, HIV testing for TB patients, TB screening for people living with HIV and IPT have increased significantly, progress is still limited in many countries. There is considerable variance in the timing and content of national policies compared with WHO guidelines. Missed opportunities to implement new scientific evidence and delayed adaptation of existing WHO guidance remains a key challenge for many countries. PMID:25216827

  16. Microstructural Variations Across a Dissimilar 316L Austenitic: 9Cr Reduced Activation Ferritic Martensitic Steel Weld Joint

    Thomas Paul, V.; Karthikeyan, T.; Dasgupta, Arup; Sudha, C.; Hajra, R. N.; Albert, S. K.; Saroja, S.; Jayakumar, T.

    2016-03-01

    This paper discuss the microstructural variations across a dissimilar weld joint between SS316 and 9Cr-RAFM steel and its modifications on post weld heat treatments (PWHT). Detailed characterization showed a mixed microstructure of austenite and martensite in the weld which is in agreement with the phases predicted using Schaeffler diagram based on composition measurements. The presence of very low volume fraction of δ-ferrite in SS316L has been identified employing state of the art electron back-scattered diffraction technique. PWHT of the ferritic steel did not reduce the hardness in the weld metal. Thermal exposure at 973 K (700 °C) showed a progressive reduction in hardness of weld joint with duration of treatment except in austenitic base metal. However, diffusion annealing at 1073 K (800 °C) for 100 hours resulted in an unexpected increase in hardness of weld metal, which is a manifestation of the dilution effects and enrichment of Ni on the transformation characteristics of the weld zone. Migration of carbon from ferritic steel aided the precipitation of fine carbides in the austenitic base metal on annealing at 973 K (700 °C); but enhanced diffusion at 1073 K (880 °C) resulted in coarsening of carbides and thereby reduction of hardness.

That hardware is modified to use active electrodes, instead of passive electrodes, for acquiring electroencephalographic signals. The application has been given to the interface has been a speller P300; for which has used the BC12000 open software that has the necessary configuration for the application. P300 speller has used a protocol in each session so that could be standardize the method to different users. Valuing the results with three neuropsychological tests, was within the objectives; however, has not been achieved by the limitation in time of project implementation. A brain computer interface has been used with passive electrodes; implemented in the same way that the BCI with active electrodes; and has worked better than the interface with active electrodes. One of the major advantages that has been observed of passive electrodes on the actives has been the size of the same, because the liabilities are smaller and therefore, easier to place preventing the hair of the user, which increases the noise in the signal.

  4. Joint Convention on the safety of spent fuel management and on the safety of radioactive waste management. Second national report on implementation by France of its obligations under the convention

    The Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management, hereinafter referred to as the 'Joint Convention', is the result of international discussions which took place following adoption of the Convention on Nuclear Safety in 1994. France signed the Joint Convention on 29 September 1997, the first day on which it was opened for signature, during the General Conference of the International Atomic Energy Agency (IAEA). France approved it on 22 February 2000 and deposited the corresponding instruments with the IAEA on 27 April 2000. The Joint Convention entered into force on 18 June 2001. For many years, France has been taking an active part in international action to reinforce nuclear safety and it considers the Joint Convention to be a key step in this direction. The fields it covers have for a long time been part of the French approach to nuclear safety. This report, which is the second of its kind, is published in accordance with article 32 of the Joint Convention and presents the measures taken by France to meet each of the obligations set out in the Convention. The facilities and radioactive materials which are the subject of this Convention are of widely differing types and in France are covered by different regulatory authorities, as explained in section E of this report. Above a certain radioactive content threshold, a facility is referred to as a 'basic nuclear installation' (BNI) and is placed under the authority of the Nuclear Safety Authority. This category includes in particular all facilities receiving spent fuel (reactors, reprocessing plants, storage facilities, etc.), most of the facilities whose 'main purpose is management of radioactive waste' as defined by this Convention, and a large number of facilities containing radioactive waste, even if management of the waste is not their primary objective: the total number of all types of BNIs is about 125 facilities. Below this threshold, an

  5. Development, Implementation and Experimental Validations of Activation Products Models for Water Pool Reactors

    Some parameters were obtained both calculations and experiments in order to determined the source of the meaning activation products in water pool reactors. In this case, the study was done in RA-6 reactor (Centro Atomico Bariloche - Argentina).In normal operation, neutron flux on core activates aluminium plates.The activity on coolant water came from its impurities activation and meanly from some quantity of aluminium that, once activated, leave the cladding and is transported by water cooling system.This quantity depends of the 'recoil range' of each activation reaction.The 'staying time' on pool (the time that nuclides are circulating on the reactor pool) is another characteristic parameter of the system.Stationary state activity of some nuclides depends of this time.Also, several theoretical models of activation on coolant water system are showed, and their experimental validations

  9. Temporomandibular joint imaging

    The temporomandibular joint (TMJ) though close to the surface is one of the most difficult structures to visualise effectively. This is mainly due to the presence of dense bony structures which become superimposed over the image of the joint. The need to visualise this anatomical area is on the increase as more and more patients actively seek treatment for problems related to, and associated with, the craniomandibular articulation. Conventional radiographic techniques used to evaluate the joint have been designed to cope with the unique combination of hard and soft tissues and airspaces found in the maxillofacial region, but still have limitations. With the advent of the space age with its new materials, silicon chips and microcomputers, radiography has given way to diagnostic imaging which covers a range of modalities such as computerised tomography, magnetic resonance imaging, ultrasound and thermography. These are now available to assist in obtaining a clearer picture of the internal structures of the TMJ without the problems of superimposition previously encountered. This article is a resume of the radiographic techniques and a review of the current imaging methods available for assessing disorders of the temporomandibular joint. 21 refs., 3 tabs., 14 figs

    2016-05-01

    Functional performance of total knee replacement (TKR) is often assessed using skin marker-based stereophotogrammetry, which can be affected by soft tissue artifacts (STA). The current study aimed to compare the STA and their effects on the kinematics of the knee between twelve patients with TKR and twelve healthy controls during sit-to-stand, and to assess the effects of STA on the statistical between-group comparisons. Each subject performed the sit-to-stand task while motions of the skin markers and the knees were measured by a motion capture system integrated with a three-dimensional fluoroscopy technique. The bone motions measured by the three-dimensional fluoroscopy were taken as the gold standard, with respect to which the STA of the markers were obtained. The STA were found to affect the calculated segmental poses and knee kinematics between the groups differently. The STA resulted in artefactual posterior displacements of the knee joint center, with magnitudes significantly greater in TKR than controls (ptrue between-group differences in the anterior-posterior translation and internal/external rotation of knee while leading to false significant between-group differences in the abduction/adduction and proximal-distal translation.

  18. Concurrent validation of Xsens MVN measurement of lower limb joint angular kinematics

    This study aims to validate a commercially available inertial sensor based motion capture system, Xsens MVN BIOMECH using its native protocols, against a camera-based motion capture system for the measurement of joint angular kinematics. Performance was evaluated by comparing waveform similarity using range of motion, mean error and a new formulation of the coefficient of multiple correlation (CMC). Three dimensional joint angles of the lower limbs were determined for ten healthy subjects while they performed three daily activities: level walking, stair ascent, and stair descent. Under all three walking conditions, the Xsens system most accurately determined the flexion/extension joint angle (CMC > 0.96) for all joints. The joint angle measurements associated with the other two joint axes had lower correlation including complex CMC values. The poor correlation in the other two joint axes is most likely due to differences in the anatomical frame definition of limb segments used by the Xsens and Optotrak systems. Implementation of a protocol to align these two systems is necessary when comparing joint angle waveforms measured by the Xsens and other motion capture systems. (note)

  9. Imaging active faulting in a region of distributed deformation from the joint clustering of focal mechanisms and hypocentres: Application to the Azores-western Mediterranean region

    Custódio, Susana; Lima, Vânia; Vales, Dina; Cesca, Simone; Carrilho, Fernando

    2016-04-01

    The matching between linear trends of hypocentres and fault planes indicated by focal mechanisms (FMs) is frequently used to infer the location and geometry of active faults. This practice works well in regions of fast lithospheric deformation, where earthquake patterns are clear and major structures accommodate the bulk of deformation, but typically fails in regions of slow and distributed deformation. We present a new joint FM and hypocentre cluster algorithm that is able to detect systematically the consistency between hypocentre lineations and FMs, even in regions of distributed deformation. We apply the method to the Azores-western Mediterranean region, with particular emphasis on western Iberia. The analysis relies on a compilation of hypocentres and FMs taken from regional and global earthquake catalogues, academic theses and technical reports, complemented by new FMs for western Iberia. The joint clustering algorithm images both well-known and new seismo-tectonic features. The Azores triple junction is characterised by FMs with vertical pressure (P) axes, in good agreement with the divergent setting, and the Iberian domain is characterised by NW-SE oriented P axes, indicating a response of the lithosphere to the ongoing oblique convergence between Nubia and Eurasia. Several earthquakes remain unclustered in the western Mediterranean domain, which may indicate a response to local stresses. The major regions of consistent faulting that we identify are the mid-Atlantic ridge, the Terceira rift, the Trans-Alboran shear zone and the north coast of Algeria. In addition, other smaller earthquake clusters present a good match between epicentre lineations and FM fault planes. These clusters may signal single active faults or wide zones of distributed but consistent faulting. Mainland Portugal is dominated by strike-slip earthquakes with fault planes coincident with the predominant NNE-SSW and WNW-ESE oriented earthquake lineations. Clusters offshore SW Iberia are

  14. Graphical processing unit implementation of an integrated shape-based active contour: Application to digital pathology

    Sahirzeeshan Ali

    2011-01-01

    Full Text Available Commodity graphics hardware has become a cost-effective parallel platform to solve many general computational problems. In medical imaging and more so in digital pathology, segmentation of multiple structures on high-resolution images, is often a complex and computationally expensive task. Shape-based level set segmentation has recently emerged as a natural solution to segmenting overlapping and occluded objects. However the flexibility of the level set method has traditionally resulted in long computation times and therefore might have limited clinical utility. The processing times even for moderately sized images could run into several hours of computation time. Hence there is a clear need to accelerate these segmentations schemes. In this paper, we present a parallel implementation of a computationally heavy segmentation scheme on a graphical processing unit (GPU. The segmentation scheme incorporates level sets with shape priors to segment multiple overlapping nuclei from very large digital pathology images. We report a speedup of 19× compared to multithreaded C and MATLAB-based implementations of the same scheme, albeit with slight reduction in accuracy. Our GPU-based segmentation scheme was rigorously and quantitatively evaluated for the problem of nuclei segmentation and overlap resolution on digitized histopathology images corresponding to breast and prostate biopsy tissue specimens.

    Full Text Available The education of the employees in each instance of company comes with the purpose to gain competences and experience in order to realize every business process in accordance with the requests of the products/ services, legal obligation and competitiveness criteria, as well as with the appointing of the employees requests, and all that with the intention to achieve quality where it is necessary to involve everyone in their own field. In this paper the following inputs are being given in order to get a clear picture if Macedonian companies are keen on to learning and stimulating the individual and collective learning as to improve the results in general. According to the given results in the research, it is stated that Macedonian companies do not care about the quality, insufficiently pay attention to the continuous education, make small investments in the innovations and over all, the quality system is built in a very small number of companies. In this paper the following model for a successful designing and implementing of the educational system as a subsystem of the house of quality is suggested. This methodology is integral and universal meaning it is applicable to all companies and institutions. Without a given training about TQM (Total Quality Management philosophy and a continued education provided firstly to the managers and further on to all the employees, the TQM strategy could not be implemented as well as the benefits that come with the quality system.

  16. Action Research on the Implementation of Active Learning at an Elementary School in Aceh

    Syamsul Bahri Ys

    2011-12-01

    Full Text Available Teachers in the state elementary schools and state Islamic elementary schools of the Indonesian province of Aceh have been trained repeatedly over the past several years on a variety of educational reform initiatives. One of the most important of these has been the effort to promote teaching for active learning in Acehnese schools. Research in other countries, and past experience with teacher training efforts in Aceh, suggest that such a transformation in classroom practice will not be easy. In order to investigate whether and how teachers were transferring their training in active learning into actual classroom practice, a team of lecturers from three universities in Banda Aceh conducted an action research project in one state elementary school. We found that teachers’, principals’, and school supervisors’ understanding of teaching for active learning remained extremely tentative months after receiving training in active learning, and their tentative understanding prevented their active experimentation with what they had learned. A brief retraining session focused on arriving at a common understanding of the concept, committed school leadership, and learning from peers appeared to have a significant impact on teachers’ willingness and ability to try to teach for active learning. Key Words: Active Learning, Action Research, Aceh, Elementary Schools

    Full Text Available Objective. To assess efficacy and tolerability of diclofenac-emulgel local application in comparison with oral ibuprofen administration for the treatment of active interphalangeal hand joints osteoarthritis (Heberden and/or Bushar nodules. Material and methods. 321 pts were randomized into two groups. Diclofenac-emulgel (active drug and placebo ibuprofen tablets were administered in one of them, placebo diclofenac-emulgel and ibuprofen tablets (active drug — in the other. Diclofenac was administered as 10 cm strip locally 4 times a day and 400 mg of ibuprofen were given 3 times a day. Frequency of improvement was used as the main outcome measure. Improvement was registered if pain on 100 mm visual analog scale decreased at least by 40%. Disease activity, pain at rest, pain at movement, morning stiffness, grip strength and quality of life were used as additional outcome measures. Results. To the end of treatment according to 5% lower equivalency limit local therapy was at least as effective as oral administration of ibuprofen (p=0,007. Administration of both treatment methods provided also comparable improvement of all additional outcome measures. Both treatment methods showed good tolerability but more pts with receiving ibuprofen experienced serious adverse events than those using diclofenac (9 and 4 pts respectively. There was also similar proportion of pts prematurely withdrawn due to side effects (n=21: 5 (3% from them received diclofenac and 16 (10% - ibuprofen. Similar ratio of adverse events attributed to study treatment was revealed. Such events were present in 2 pts using diclofenac and in 13 (8,3% receiving ibuprofen. Most of these events applied to gastrointestinal tract (in 1 pt using diclofenac and in 8 pts receiving ibuprofen. Conclusion. Local treatment of active interphalangeal hand joints osteoarthritis (Heberden and/or Bushar nodules with diclofenac is at least as effective as systemic administration of ibuprofen

  18. Economic evaluation of active implementation versus guideline dissemination for evidence-based care of acute low-back pain in a general practice setting.

    Duncan Mortimer

    Full Text Available INTRODUCTION: The development and publication of clinical practice guidelines for acute low-back pain has resulted in evidence-based recommendations that have the potential to improve the quality and safety of care for acute low-back pain. Development and dissemination of guidelines may not, however, be sufficient to produce improvements in clinical practice; further investment in active implementation of guideline recommendations may be required. Further research is required to quantify the trade-off between the additional upfront cost of active implementation of guideline recommendations for low-back pain and any resulting improvements in clinical practice. METHODS: Cost-effectiveness analysis alongside the IMPLEMENT trial from a health sector perspective to compare active implementation of guideline recommendations via the IMPLEMENT intervention (plus standard dissemination against standard dissemination alone. RESULTS: The base-case analysis suggests that delivery of the IMPLEMENT intervention dominates standard dissemination (less costly and more effective, yielding savings of $135 per x-ray referral avoided (-$462.93/3.43. However, confidence intervals around point estimates for the primary outcome suggest that--irrespective of willingness to pay (WTP--we cannot be at least 95% confident that the IMPLEMENT intervention differs in value from standard dissemination. CONCLUSIONS: Our findings demonstrate that moving beyond development and dissemination to active implementation entails a significant additional upfront investment that may not be offset by health gains and/or reductions in health service utilization of sufficient magnitude to render active implementation cost-effective.

  1. Joint instability and osteoarthritis.

    Blalock, Darryl; Miller, Andrew; Tilley, Michael; Wang, Jinxi

    2015-01-01

    Joint instability creates a clinical and economic burden in the health care system. Injuries and disorders that directly damage the joint structure or lead to joint instability are highly associated with osteoarthritis (OA). Thus, understanding the physiology of joint stability and the mechanisms of joint instability-induced OA is of clinical significance. The first section of this review discusses the structure and function of major joint tissues, including periarticular muscles, which play a significant role in joint stability. Because the knee, ankle, and shoulder joints demonstrate a high incidence of ligament injury and joint instability, the second section summarizes the mechanisms of ligament injury-associated joint instability of these joints. The final section highlights the recent advances in the understanding of the mechanical and biological mechanisms of joint instability-induced OA. These advances may lead to new opportunities for clinical intervention in the prevention and early treatment of OA. PMID:25741184

  8. Analysis of normative requirements for the development and implementation of a quality management system in Brazilian nuclear installations and activities

    The present work identifies, characterizes and analyses the normative requirements for the development and implementation of quality management systems in Brazilian nuclear installations and activities. The requirements established in standards IAEA GS-R-3, IAEA GS-G-3.1, IAEA DS 349, NBR ISO 9001:2000 e CNEN-NN-1.16 are critically analyzed. A correlation matrix of the applicable standards is presented and the related topics among them are identified. The standards IAEA GS-R-3, IAEA GS-G-3.1 and IAEA DS 349 define general requirements for establishing, implementing, assessing and continually improving an integrated management system in nuclear installations and activities, in IAEA member countries. The standard NBR ISO 9001:2000 establishes general requirements for the implementation of a quality management system in all kinds of organizations. The standard CNEN NN-1.16 establishes the regulating requirements for the quality assurance systems and programs of nuclear installations, for licensing and authorization for operation of these installations in Brazil. The standard IAEA GS-R-3 that replaces the code IAEA 50-C-Q introduces the concept of 'Integrated Management System' for the nuclear area, in preference to the concepts of 'Quality Assurance' and 'Quality Management'. This new approach is aligned with the current tendency incorporating requirements of quality, safety, health, environment, security, economics and other in a unique management system. Examples of quality management systems implemented by Brazilian nuclear organizations and by nuclear organizations outside Brazil are analyzed and considered in the discussion of results. (author)

  9. Robot Control near Singularity and Joint Limit Using a Continuous Task Transition Algorithm

    Hyejin Han

    2013-10-01

    Full Text Available When robots are controlled in the task space, singularities and joint limits are among the most critical and difficult issues that can arise. In this paper, we propose a new approach for the robots to operate in the regions near singularities and joint limits using the operational space control framework. Specifically, a continuous task transition algorithm called the intermediate desired value approach is applied to the hierarchically structured controller in the operational space control framework. In this approach, new tasks are defined for dealing with singularities and joint limits, and the tasks are activated or deactivated using the continuous task transition algorithm to guarantee the continuous execution of the tasks during the execution of the main task. The proposed approach is implemented on a 6-DOF manipulator called Roman-MD. The experimental results demonstrate its performance near the singular regions and joint limits.

  10. Spacesuit mobility knee joints

    Vykukal, H. C. (Inventor)

    1979-01-01

    Pressure suit mobility joints are for use in interconnecting adjacent segments of an hermetically sealed spacesuit in which low torques, low leakage and a high degree of reliability are required. Each of the joints is a special purpose joint characterized by substantially constant volume and low torque characteristics and includes linkages which restrain the joint from longitudinal distension and includes a flexible, substantially impermeable diaphragm of tubular configuration spanning the distance between pivotally supported annuli. The diaphragms of selected joints include rolling convolutions for balancing the joints, while various joints include wedge-shaped sections which enhance the range of motion for the joints.

  12. Activation and implementation of a Federal Radiological Monitoring and Assessment Center

    The Nevada Operations Office of the U.S. Department of Energy (DOE/NV) has been assigned the primary responsibility for responding to a major radiological emergency. The initial response to any radiological emergency, however, will probably be conducted under the DOE regional radiological assistance plan (RAP). If the dimensions of the crisis demand federal assistance, the following sequence of events may be anticipated: (1) DOE regional RAP response, (2) activation of the Federal Radiological Monitoring and Assistance Center (FRMAC) requested, (3) aerial measuring systems and DOE/NV advance party respond, (4) FRMAC activated, (5) FRMAC responds to state(s) and cognizant federal agency (CFA), and (6) management of FRMAC transferred to the Environmental Protection Agency (EPA). The paper discusses activation channels, authorization, notification, deployment, and interfaces

  19. Key programmatic steps and activities for implementing the Uranium Mill Tailings Remedial Action Project

    The Uranium Mill Tailings Radiation Control Act of 1978 (UMTRCA) was enacted based upon findings by Congress ''that uranium mill tailings located at active and inactive hazard to the public, and that protection of the public health, safety and welfare, and the regulations of interstate commerce, require that every reasonable effort be made to provide for the stabilization, disposal, and control in a safe and environmentally sound manner of such tailings in order to prevent or minimize radon diffusion into the environment and to prevent or minimize other environmental hazards from such tailings.'' A general understanding of the steps leading to elimination of the hazards associated with designated uranium mill tailings sites, and the parties involved in that effort, are presented in this document. A representative schedule is also presented in this document to show both program sequence and activity interdependence. Those activities that have the most potential to influence program duration, because of the significant amount of additional time that may be required, include identification and selection of a suitable site, field data collection delays due to weather, actual acquisition of the designated or alternate disposal site, construction delays due to weather, and site licensing. This document provides an understanding of the steps, the sequence, the parties involved, and a representative duration of activities leading to remedial action and cleanup at the designated inactive uranium mill tailings sites. 10 refs., 5 figs., 1 tab

  3. BSMac: a MATLAB toolbox implementing a Bayesian spatial model for brain activation and connectivity.

    Zhang, Lijun; Agravat, Sanjay; Derado, Gordana; Chen, Shuo; McIntosh, Belinda J; Bowman, F DuBois

    2012-02-15

    We present a statistical and graphical visualization MATLAB toolbox for the analysis of functional magnetic resonance imaging (fMRI) data, called the Bayesian Spatial Model for activation and connectivity (BSMac). BSMac simultaneously performs whole-brain activation analyses at the voxel and region of interest (ROI) levels as well as task-related functional connectivity (FC) analyses using a flexible Bayesian modeling framework (Bowman et al., 2008). BSMac allows for inputting data in either Analyze or Nifti file formats. The user provides information pertaining to subgroup memberships, scanning sessions, and experimental tasks (stimuli), from which the design matrix is constructed. BSMac then performs parameter estimation based on Markov Chain Monte Carlo (MCMC) methods and generates plots for activation and FC, such as interactive 2D maps of voxel and region-level task-related changes in neural activity and animated 3D graphics of the FC results. The toolbox can be downloaded from http://www.sph.emory.edu/bios/CBIS/. We illustrate the BSMac toolbox through an application to an fMRI study of working memory in patients with schizophrenia.

  6. Monosodium iodoacetate-induced joint pain is associated with increased phosphorylation of mitogen activated protein kinases in the rat spinal cord

    Jarvis Michael F

    2011-05-01

    Full Text Available Abstract Background Intra-articular injection of monosodium iodoacetate (MIA in the knee joint of rats disrupts chondrocyte metabolism resulting in cartilage degeneration and subsequent nociceptive behavior that has been described as a model of osteoarthritis (OA pain. Central sensitization through activation of mitogen activated protein kinases (MAPKs is recognized as a pathogenic mechanism in chronic pain. In the present studies, induction of central sensitization as indicated by spinal dorsal horn MAPK activation, specifically ERK and p38 phosphorylation, was assessed in the MIA-OA model. Results Behaviorally, MIA-injected rats displayed reduced hind limb grip force 1, 2, and 3 weeks post-MIA treatment. In the same animals, activation of phospho ERK1/2 was gradually increased, reaching a significant level at post injection week 3. Conversely, phosphorylation of p38 MAPK was enhanced maximally at post injection week 1 and decreased, but remained elevated, thereafter. Double labeling from 3-wk MIA rats demonstrated spinal pERK1/2 expression in neurons, but not glia. In contrast, p-p38 was expressed by microglia and a subpopulation of neurons, but not astrocytes. Additionally, there was increased ipsilateral expression of microglia, but not astrocytes, in 3-wk MIA-OA rats. Consistent with increased MAPK immunoreactivity in the contralateral dorsal horn, mechanical allodynia to the contralateral hind-limb was observed 3-wk following MIA. Finally, intrathecal injection of the MEK1 inhibitor PD98059 blocked both reduced hind-limb grip force and pERK1/2 induction in MIA-OA rats. Conclusion Results of these studies support the role of MAPK activation in the progression and maintenance of central sensitization in the MIA-OA experimental pain model.

  7. Goal striving strategies and effort mobilization: When implementation intentions reduce effort-related cardiac activity during task performance.

    Freydefont, Laure; Gollwitzer, Peter M; Oettingen, Gabriele

    2016-09-01

    Two experiments investigate the influence of goal and implementation intentions on effort mobilization during task performance. Although numerous studies have demonstrated the beneficial effects of setting goals and making plans on performance, the effects of goals and plans on effort-related cardiac activity and especially the cardiac preejection period (PEP) during goal striving have not yet been addressed. According to the Motivational Intensity Theory, participants should increase effort mobilization proportionally to task difficulty as long as success is possible and justified. Forming goals and making plans should allow for reduced effort mobilization when participants perform an easy task. However, when the task is difficult, goals and plans should differ in their effect on effort mobilization. Participants who set goals should disengage, whereas participants who made if-then plans should stay in the field showing high effort mobilization during task performance. As expected, using an easy task in Experiment 1, we observed a lower cardiac PEP in both the implementation intention and the goal intention condition than in the control condition. In Experiment 2, we varied task difficulty and demonstrated that while participants with a mere goal intention disengaged from difficult tasks, participants with an implementation intention increased effort mobilization proportionally with task difficulty. These findings demonstrate the influence of goal striving strategies (i.e., mere goals vs. if-then plans) on effort mobilization during task performance. PMID:27374255

  12. Microstructural characterization of weld joints of 9Cr reduced activation ferritic martensitic steel fabricated by different joining methods

    Thomas Paul, V.; Saroja, S.; Albert, S.K.; Jayakumar, T.; Rajendra Kumar, E., E-mail: vtp@igcar.gov.in

    2014-10-15

    This paper presents a detailed electron microscopy study on the microstructure of various regions of weldment fabricated by three welding methods namely tungsten inert gas welding, electron beam welding and laser beam welding in an indigenously developed 9Cr reduced activation ferritic/martensitic steel. Electron back scatter diffraction studies showed a random micro-texture in all the three welds. Microstructural changes during thermal exposures were studied and corroborated with hardness and optimized conditions for the post weld heat treatment have been identified for this steel. Hollomon–Jaffe parameter has been used to estimate the extent of tempering. The activation energy for the tempering process has been evaluated and found to be corresponding to interstitial diffusion of carbon in ferrite matrix. The type and microchemistry of secondary phases in different regions of the weldment have been identified by analytical transmission electron microscopy. - Highlights: • Comparison of microstructural parameters in TIG, electron beam and laser welds of RAFM steel • EBSD studies to illustrate the absence of preferred orientation and identification of prior austenite grain size using phase identification map • Optimization of PWHT conditions for indigenous RAFM steel • Study of kinetics of tempering and estimation of apparent activation energy of the process.

  13. MRI of the hip joint

    Magnetic resonance imaging (MRI) is performed to diagnose many pathologic conditions affecting the hip joint. Either conventional MRI (without contrast enhancement of the joint cavity) or MR arthrography is used to detect and most accurately differentiate hip joint pathologies. Conventional MRI is performed in cases of bone marrow edema, necrosis, arthrosis and especially the so-called ''activated arthrosis'', as well as in inflammatory and tumorous entities. MR arthography, which has only recently become available for use, is excellently suited for diagnosing lesions of the acetabular labrum, cartilage lesions, and free articular bodies. This article provides an overview about MRI characteristics and their accuracy of hip joint diseases and the impact on the therapeutic procedure. (orig.)

    2010-11-01

    Full Text Available This paper aims to explore factors, which influence the process of activity-based costing (ABC implementation, as well as analyze and explain the changes in the area of methodology and organization of a company, after activity-based costing implementation. The research findings are of both theoretical and practical importance. From the practical point of view, companies considering implementation of ABC should be aware of the positive and negative factors conditioning the process of implementation; in addition, they should be familiar with methodological and organizational changes, which might stem from the ABC implementation. From the theoretical point of view, this research might be helpful in determining a more general tendency: although modifications in cost accounting systems and implementation of modern methods of management accounting in Polish companies come later than in more developed economies, the tendency heads in the same direction.

  19. An institutional sociology perspective of the implementation of activity based costing by Spanish health care institutions

    Eriksen, Scott D.; Urrutia, Ignacio

    2005-01-01

    According to institutional sociology, hospitals will respond to external environmental pressures and adopt Activity-Based-Costing (ABC). This theory overemphasizes conformity and fails to consider the advantages of organizational non-conformance. A conflict of interests between physicians and management leads to physician resistance to accepting ABC. This paper investigates the Spanish government's response to this resistance by creating new public foundation hospitals, and involves a case st...

The proposed converter has zero-voltageswitching (ZVS) operations of both...

  1. The design and implementation of EPL: An event pattern language for active databases

    Giuffrida, G.; Zaniolo, C.

    1994-01-01

    The growing demand for intelligent information systems requires closer coupling of rule-based reasoning engines, such as CLIPS, with advanced data base management systems (DBMS). For instance, several commercial DBMS now support the notion of triggers that monitor events and transactions occurring in the database and fire induced actions, which perform a variety of critical functions, including safeguarding the integrity of data, monitoring access, and recording volatile information needed by administrators, analysts, and expert systems to perform assorted tasks; examples of these tasks include security enforcement, market studies, knowledge discovery, and link analysis. At UCLA, we designed and implemented the event pattern language (EPL) which is capable of detecting and acting upon complex patterns of events which are temporally related to each other. For instance, a plant manager should be notified when a certain pattern of overheating repeats itself over time in a chemical process; likewise, proper notification is required when a suspicious sequence of bank transactions is executed within a certain time limit. The EPL prototype is built in CLIPS to operate on top of Sybase, a commercial relational DBMS, where actions can be triggered by events such as simple database updates, insertions, and deletions. The rule-based syntax of EPL allows the sequences of goals in rules to be interpreted as sequences of temporal events; each goal can correspond to either (1) a simple event, or (2) a (possibly negated) event/condition predicate, or (3) a complex event defined as the disjunction and repetition of other events. Various extensions have been added to CLIPS in order to tailor the interface with Sybase and its open client/server architecture.

  2. Activation of Natural Killer Cells in Patients with Chronic Bone and Joint Infection due to Staphylococci Expressing or Not the Small Colony Variant Phenotype

    Sébastien Viel

    2014-01-01

    Full Text Available Chronic bone and joint infections (BJI are devastating diseases. Relapses are frequently observed, as some pathogens, especially staphylococci, can persist intracellularly by expressing a particular phenotype called small colony variant (SCV. As natural killer (NK cells are lymphocytes specialized in the killing of host cells infected by intracellular pathogens, we studied NK cells of patients with chronic BJI due to staphylococci expressing or not SCVs (10 patients in both groups. Controls were patients infected with other bacteria without detectable expression of SCVs, and healthy volunteers. NK cell phenotype was evaluated from PBMCs by flow cytometry. Degranulation capacity was evaluated after stimulation with K562 cells in vitro. We found that NK cells were activated in terms of CD69 expression, loss of CD16 and perforin, in all infected patients in comparison with healthy volunteers, independently of the SCV phenotype. Peripheral NK cells in patients with chronic BJI display signs of recent activation and degranulation in vivo in response to CD16-mediated signals, regardless of the type of bacteria involved. This could involve a universal capacity of isolates responsible for chronic BJI to produce undetectable SCVs in vivo, which might be a target of future intervention.

  3. Intercomparison of personal dose equivalent measurements by active personal dosimeters. Final report of a joint IAEA-EURADOS project

    Active personal dosimeters (APD) are widely used in many countries, i.e. in the medical field and as operational dosimeters in nuclear power plants. Their use as legal dosimeters is already established in a few countries, and will increase in the near future. In the majority of countries, APDs have not undergone accreditation programmes or intercomparisons. In 2001, an EURADOS (European Radiation Dosimetry Group) Working Group on harmonization of individual monitoring was formed, funded by the European Commission, in the fifth framework programme, and by the participating institutes. The work addressed four issues; inter alia also an inventory of new developments in individual monitoring with an emphasis on the possibilities and performance of active (electronic) dosimeters for both photon/beta and neutron dosimetry. Within the work on this issue, a catalogue of the most extensively used active personal dosimeters (APDs) suitable for individual monitoring was made. On the basis of the knowledge gained in this activity, the organization of an international intercomparison, which would address APDs, was considered of great value to the dosimetric community. The IAEA in cooperation with EURADOS organized such an intercomparison in which most of the testing criteria as described in two internationally accepted standards (IEC61526 and IEC61283) were used. Additionally, simulated workplace fields were used for testing the APD reactions to pulsed X ray fields and mixed gamma/X ray fields. This is the first time that results of comparisons of such types are published, which is of great importance for APD end users in medical diagnostic and surgery X ray applications. Nine suppliers from six countries in Europe and the USA participated in the intercomparison with 13 different models. One of the models was a special design for extremity dose measurements. Irradiations and readout was done by two accredited calibration laboratories in Belgium and France and the French

  4. Management of High Activity Sealed Sources in the European Union: HASS Directive implementation status and legal developments

    European Union Council Directive 2003/122/Euratom of 22 December 2003 on the control of high-activity sealed radioactive sources and orphan sources (HASS Directive) requires EU Member States to put in place several measures in order to guarantee the safety and security of high activity sealed radioactive sources (HASS) and to search for orphan sources. These legally binding measures are in line with the requirements of the IAEA Code of Conduct on the Safety and Security of Radioactive Sources. The paper discusses the results of the recent HASS Directive implementation review and the results of a supporting study project under the EU action plan on chemical, biological, radiological and nuclear security. The paper also outlines the current development of the HASS legislation in the European Union, especially in terms of the proposed new EU Basic Safety Standards Directive. (author)

  5. Consideration and research of high voltage insulation strategy for ITER Feeder busbar joint

    Highlights: • Several rounds insulation trials for ITER Feeder joint were carried out in ASIPP. • Wet-winding, VPI were practiced and attempt for the best impregnation strategy. • Improvement of wet-winding technology with vacuum assistance was realized. • To supplement the electrical test, DR technology was explored for insulation quality inspection. -- Abstract: The ITER Feeder busbar joint is an important component which connects different sections of busbar which run from the high temperature superconducting current leads to the magnet terminals. High voltage insulated bus bar sections will be assembled onto the feeder support structure (called the containment duct), and the joints between sections will be made in situ. The high voltage insulation over the joint is the final step to complete the insulation of the whole bus bar system, and its quality is key to achieving the required electrical performance of the system. The final joint has a complex external configuration with an irregular structure in places, which makes it difficult for the application of the insulation. The limited access in the Feeder and the complex joint external structure make the implementation of the joint insulation hard to solve. The Feeder group at ASIPP has carried out significant R and D for the joint insulation, involving research on the selection of materials, the design of the insulation structure, the curing technology and the quality inspection method. After many rounds of manufacturing and testing, the insulation strategy for the Feeder joint will focus on the so-called “wet-winding” technology. Despite the fact that this process has some intrinsic disadvantages, it is more appropriate for the joint structure compared to other methods. The sub-suppliers to ASIPP have chosen this impregnation method for the feeder qualification activities based on guidance from ASIPP. This paper describes the research procedure of the ITER Feeder busbar joint insulation

    2014-05-01

    Full Text Available Purpose: The primary aim is to describe the development and implementation of a smartphone application (app designed to promote physical activity and reduce screen-time in adolescent boys ‘at risk’ of obesity from low-income communities.Methods: An app was developed to support the delivery of a face-to-face school-based obesity prevention program known as the ‘Active Teen Leaders Avoiding Screen-time’ (ATLAS program. ATLAS was guided by self-determination theory and social cognitive theory and evaluated using a cluster randomized controlled trial with 361 boys (12.7± 0.5 years in 14 secondary schools. Following the completion of the study, participants in the intervention group completed a process evaluation questionnaire and focus groups were conducted with 42 students to explore their general perceptions of the ATLAS program and their experience with the smartphone app. Barriers and challenges encountered in the development, implementation and evaluation of the app are also described.Results: Participation in the study was not contingent on ownership of a smartphone, but 70% of participants in the intervention group reported having access to a smartphone or tablet device. Focus group participants reported an enjoyment of the program, and felt that it had provided them with new skills, techniques, and routines for the future. However, their engagement with the smartphone app was limited, due to a variety of reasons. Barriers to the implementation and evaluation of the app included limited access to smartphone devices, technical problems with the push notifications, lack of access to usage data and the challenges of maintaining participants’ interest in using the app.Conclusions: Although participants reported high levels of satisfaction with the ATLAS program in general, the smartphone app was not used extensively. Additional strategies and features may be needed to enhance engagement in adolescent boys.

  7. Lithium enrichment on the single active K1-giant DI Piscium -- Possible joint origin of differential rotation and Li enrichment

    Kriskovics, L; Vida, K; Granzer, T; Oláh, K

    2014-01-01

    We investigate the surface spot activity of the rapidly rotating, lithium-rich active single K-giant DI Psc to measure the surface differential rotation and understand the mechanisms behind the Li-enrichment. Doppler imaging was applied to recover the surface temperature distribution of DI Psc in two subsequent rotational cycles using the individual mapping lines Ca I 6439, Fe I 6430, Fe I 6421 and Li I 6708. Surface differential rotation was derived by cross-correlation of the subsequent maps. Difference maps are produced to study the uniformity of Li-enrichment on the surface. These maps are compared with the rotational modulation of the Li I 6708 line equivalent width. Doppler images obtained for the Ca and Fe mapping lines agree well and reveal strong polar spottedness, as well as cool features at lower latitudes. Cross-correlating the consecutive maps yields antisolar differential rotation with shear coefficient -0.083 +- 0.021. The difference of the average and the Li maps indicates that the lithium abu...

  9. Activation of voltage-gated KCNQ/Kv7 channels by anticonvulsant retigabine attenuates mechanical allodynia of inflammatory temporomandibular joint in rats

    Xu Wen

    2010-08-01

    Full Text Available Abstract Background Temporomandibular disorders (TMDs are characterized by persistent orofacial pain and have diverse etiologic factors that are not well understood. It is thought that central sensitization leads to neuronal hyperexcitability and contributes to hyperalgesia and spontaneous pain. Nonsteroidal anti-inflammatory drugs (NSAIDs are currently the first choice of drug to relieve TMD pain. NSAIDS were shown to exhibit anticonvulsant properties and suppress cortical neuron activities by enhancing neuronal voltage-gated potassium KCNQ/Kv7 channels (M-current, suggesting that specific activation of M-current might be beneficial for TMD pain. Results In this study, we selected a new anticonvulsant drug retigabine that specifically activates M-current, and investigated the effect of retigabine on inflammation of the temporomandibular joint (TMJ induced by complete Freund's adjuvant (CFA in rats. The results show that the head withdrawal threshold for escape from mechanical stimulation applied to facial skin over the TMJ in inflamed rats was significantly lower than that in control rats. Administration of centrally acting M-channel opener retigabine (2.5 and 7.5 mg/kg can dose-dependently raise the head withdrawal threshold of mechanical allodynia, and this analgesic effect can be reversed by the specific KCNQ channel blocker XE991 (3 mg/kg. Food intake is known to be negatively associated with TMJ inflammation. Food intake was increased significantly by the administration of retigabine (2.5 and 7.5 mg/kg, and this effect was reversed by XE991 (3 mg/kg. Furthermore, intracerebralventricular injection of retigabine further confirmed the analgesic effect of central retigabine on inflammatory TMJ. Conclusions Our findings indicate that central sensitization is involved in inflammatory TMJ pain and pharmacological intervention for controlling central hyperexcitability by activation of neuronal KCNQ/M-channels may have therapeutic potential for

  10. Successes and Challenges in Implementation of Radon Control Activities in Iowa, 2010–2015

    Abbott, Anne L.; Miller, Laura L.

    2016-01-01

    Background Radon gas has recently become more prominent in discussions of lung cancer prevention nationally and in Iowa. A review in 2013 of cancer plans in the National Comprehensive Cancer Control Program found that 42% of cancer plans, including Iowa’s, had terminology on radon. Plans included awareness activities, home testing, remediation, policy, and policy evaluation. Community Context Iowa has the highest average radon concentrations in the United States; 70% of homes have radon concentrations above the Environmental Protection Agency’s action levels. Radon control activities in Iowa are led by the Iowa Cancer Consortium, the Iowa Department of Public Health, and the Iowa Radon Coalition. Methods A collaborative approach was used to increase levels of awareness, testing, and (if necessary) mitigation, and to introduce a comprehensive radon control policy in Iowa by engaging partners and stakeholders across the state. Outcome The multipronged approach and collaborative work in Iowa appears to have been successful in increasing awareness: the number of radon tests completed in Iowa increased by 20% from 19,600 in 2009 to 23,500 in 2014, and the number of mitigations completed by certified mitigators increased by 108% from 2,600 to more than 5,400. Interpretation Through collaboration, Iowa communities are engaged in activities that led to increases in awareness, testing, mitigation, and policy. States interested in establishing a similar program should consider a multipronged approach involving multiple entities and stakeholders with different interests and abilities. Improvements in data collection and analysis are necessary to assess impact. PMID:27079648

  11. Instrumentation amplifier implements second-order active low-pass filter with high gain factor

    A single-ended second-order active low-pass filter can simultaneously provide high gain factor and dc voltage subtraction. This makes it possible to reduce the number of components and signal processing stages needed in an application where small voltage changes are measured on the top of large dc voltage masked by a large amplitude oscillating carrier. The filter described in this paper is constructed from a conventional 3-op-amp instrumentation amplifier and five passive circuit elements. (technical design note)

  15. Design and implement for control system of active magnetic bearings based on DSP

    Cao, Jie; Cao, Lihong

    2005-12-01

    Magnetic-bearings, which support shafts with magnetic levitation rather than mechanical contact, have been in industrial use for decades. Recent technological developments, especially in digital processing and control, have made magnetic bearings a more-robust and cost-effective design solution than ever. The dynamic characteristic of electromagnetic bearing depends upon adopted controller; the active control can makes the electromagnetic bearings to realize complex control and special control. With the development of signal processing technology and modern control theory, the main parts of the control system are the digital signal-processing (DSP) electronics, a power supply, and amplifiers. An Active Magnetic Bearing (AMB) controller is mainly discussed in the paper, which is to be solved to realize this flexible control by hardware design based on DSP using TMS320C32 processor. It is proved by experiment that this kind of controller can optimize for this system, improve its stability and also have a very important referential value on the further study of AMB system.

  16. Guidelines for youth sports clubs to develop, implement, and assess health promotion within its activities.

    Kokko, Sami

    2014-05-01

    The settings approach to health promotion is a world-known concept concerning settings like city, hospital, school, and workplace. The concept has also been used in some regionally specific settings, such as island, prison, or university. However, there are still many, often noninstitutional, settings that have a lot of potential but have not yet been recognized. One of the newcomers is the youth sports club, which has the potential to reach a lot of children and adolescents and is effective, via its casual educational nature based on voluntary participation. According to research, health is an important aim for most youth sports clubs, but it has not been converted into practical actions. Indeed, the clubs often recognize the importance of healthy lifestyles, but there is a lack of understanding of what to do to reinforce it within one's activities. That is why, on the basis of the results of the Health Promoting Sports Club survey in Finland, guidelines for clubs to enhance health promotion as a part of their activities were created. The aim of this article is to present the guidelines, theirs rationale, and practical examples. PMID:24357861

  17. Wireless portable electrocardiogram and a tri-axis accelerometer implementation and application on sleep activity monitoring.

    Chang, Kang-Ming; Liu, Shin-Hong

    2011-04-01

    Night-to-night variability of sleep activity requires more home-based portable sleep monitoring instead of clinical polysomnography examination in the laboratory. In this article, a wireless sleep activity monitoring system is described. The system is light and small for the user. Sleep postures, such as supine or left/right side, were observed by a signal from a tri-axis accelerometer. An overnight electrocardiogram was also recorded with a single lead. Using an MSP430 as microcontroller, both physiological signals were transmitted by a Bluetooth chip. A Labview-based interface demonstrated the recorded signal and sleep posture. Three nights of sleep recordings were used to examine night-to-night variability. The proposed system can record overnight heart rate. Results show that sleep posture and posture change can be precisely detected via tri-axis accelerometer information. There is no significant difference within subject data sets, but there are statistically significant differences among subjects, both for heart rate and for sleep posture distribution. The wireless transmission range is also sufficient for home-based users. PMID:21413872

  19. Active spacecraft potential control for Cluster – implementation and first results

    K. Torkar

    Full Text Available Electrostatic charging of a spacecraft modifies the distribution of electrons and ions before the particles enter the sensors mounted on the spacecraft body. The floating potential of magnetospheric satellites in sunlight very often reaches several tens of volts, making measurements of the cold (several eV component of the ambient ions impossible. The plasma electron data become contaminated by large fluxes of photoelectrons attracted back into the sensors. The Cluster spacecraft are equipped with emitters of the liquid metal ion source type, producing indium ions at 5 to 9 keV energy at currents of some tens of microampere. This current shifts the equilibrium potential of the spacecraft to moderately positive values. The design and principles of the operation of the instrument for active spacecraft potential control (ASPOC are presented in detail. Experience with spacecraft potential control from the commissioning phase and the first two months of the operational phase are now available. The instrument is operated with constant ion current for most of the time, but tests have been carried out with varying currents and a "feedback" mode with the instrument EFW, which measures the spacecraft potential . That has been reduced to values according to expectations. In addition, the low energy electron measurements show substantially reduced fluxes of photoelectrons as expected. The flux decrease in photoelectrons returning to the spacecraft, however, occurs at the expense of an enlarged sheath around the spacecraft which causes problems for boom-mounted probes.

  20. Management of acromioclavicular joint injuries.

    Li, Xinning; Ma, Richard; Bedi, Asheesh; Dines, David M; Altchek, David W; Dines, Joshua S

    2014-01-01

    Acromioclavicular joint injuries are among the most common shoulder girdle injuries in athletes and most commonly result from a direct force to the acromion with the arm in an adducted position. Acromioclavicular joint injuries often present with associated injuries to the glenohumeral joint, including an increased incidence of superior labrum anterior posterior (SLAP) tears that may warrant further evaluation and treatment. Anteroposterior stability of the acromioclavicular joint is conferred by the capsule and acromioclavicular ligaments, of which the posterior and superior ligaments are the strongest. Superior-inferior stability is maintained by the coracoclavicular (conoid and trapezoid) ligaments. Type-I or type-II acromioclavicular joint injuries have been treated with sling immobilization, early shoulder motion, and physical therapy, with favorable outcomes. Return to activity can occur when normal shoulder motion and strength are obtained and the shoulder is asymptomatic as compared with the contralateral normal extremity. The management of type-III injuries remains controversial and is individualized. While a return to the previous level of functional activity with nonsurgical treatment has been documented in a number of case series, surgical reduction and coracoclavicular ligament reconstruction has been associated with a favorable outcome and can be considered in patients who place high functional demands on their shoulders or in athletes who participate in overhead sports. Surgical management is indicated for high-grade (≥type IV) acromioclavicular joint injuries to achieve anatomic reduction of the acromioclavicular joint, reconstruction of the coracoclavicular ligaments, and repair of the deltotrapezial fascia. Outcomes after surgical reconstruction of the coracoclavicular ligaments have been satisfactory with regard to achieving pain relief and return to functional activities, but further improvements in the biomechanical strength of these

  1. Multi Objective Robust Active Vibration Control for Flexure Jointed Struts of Stewart Platforms via H∞ and μ Synthesis

    Liu Lei; Wang Benli

    2008-01-01

    Active vibration control is needed for future space telescopes, space laser communication and other precision sensitive payloads which require ultra-quiet environments. A Stewart platform based hybrid isolator with 6 hybrid struts is the effective system for ac- tive/passive vibration isolation over 5-250 Hz band. Using an identification transfer matrix of the Stewart platform, the coupling analysis of six channels is provided. A dynamics model is derived, and the rigid mode is removed to keep the signal of pointing control. Multi objective robust H∞ and μ synthesis strategies, based on singular values and structured singular values respectively, are presented, which simultaneously satisfy the low frequency pointing and high frequency disturbance rejection requirements and take account of the model uncertainty, parametric uncertainty and sensor noise. Then, by performing robust stability test, it is shown that the two controllers are robust to the uncertainties, the robust stability margin of H∞ controller is less than that of μ controller, but the order of μ controller is higher than that of H∞ controller, so the balanced controller reduction is provided. Additionally, the μ controller is compared with a PI controller. The time domain simulation of the μ controller indicates that the two robust control strategies are effective for keeping the pointing command and isolating the harmonic and stochastic disturbances.

  2. Implementation of the Additional Protocol: Verification activities at uranium mines and mills

    Full text: The mining and milling of uranium is the first in a long chain of processes required to produce nuclear materials in a form suitable for use in nuclear weapons. Misuse of a declared uranium mining/milling facility, in the form of understatement of production, would be hard to detect with the same high level of confidence as afforded by classical safeguards on other parts of the nuclear fuel cycle. For these reasons, it would not be cost-effective to apply verification techniques based on classical safeguards concepts to a mining/milling facility in order to derive assurance of the absence of misuse. Indeed, these observations have been recognised in the Model Protocol (INFCIRC/540): 'the Agency shall not mechanistically or systematically seek to verify' information provided to it by States (Article 4.a.). Nevertheless, complementary access to uranium mining/milling sites 'on a selective basis in order to assure the absence of undeclared nuclear material and activities' (Article 4.a.(i)) is provided for. On this basis, therefore, this paper will focus predominantly on options other than site access, which are available to the Agency for deriving assurance that declared mining/milling operations are not misused. Such options entail the interpretation and analysis of information provided to the Agency including, for example, from declarations, monitoring import/export data, open source reports, commercial satellite imagery, aerial photographs, and information provided by Member States. Uranium mining techniques are diverse, and the inventories, flows and uranium assays which arise at various points in the process will vary considerably between mines, and over the operating cycle of an individual mine. Thus it is essentially impossible to infer any information, which can be used precisely to confirm, or otherwise, declared production by measuring or estimating any of those parameters at points within the mining/milling process. The task of attempting to

This device has a very important applications in shipbuilding industry and military systems. Moreover it’s also being extensively used in deep sea research of new species of plants and minerals, where it is practically impossible for humans to go. The most important feature of this system is the usage of ultrasonicfrequency to detect objects that are important for data collection or detection. Transmitting an ultra sonic frequency using an electronic oscillator is not a very difficult task, the real challenge is to design a reciever that could carry out a particular modulation technique to convert an ultra-sonic frequency to an audiblefrequency. In this paper, we propose aseteroscopic active SONAR proto-type. Further, we performed a seriers of expeirments using modulation techniques. The results obtained from the experiments gives us a braod understanding of the different behaviour of asignal.

    Joint involvement is a common manifestation in systemic lupus erythematosus (SLE). According to the SLE disease activity index 2000 (SLEDAI-2K), joint involvement is present in case of ≥2 joints with pain and signs of inflammation. However this definition could fail to catch all the various features of joint involvement. Alternatively the Swollen to Tender joint Ratio (STR) could be used. This new index, which was originally proposed for rheumatoid arthritis (RA) patients, is based on the cou...

    Full Text Available A performance sport is an activity which forces physical and mental limits of the possibilities of professional athlete, the performance is the result of three basic components, namely organic, psychological and social.Biological component consists of the equipping somatic physiological and gymnast, the psychological means personality with aspirational notes, will power, self-checking, creativity, ideals, and the social is linked to the education, culture and interhuman relationships. In addition to solving questions of order of psychic athlete, preparing psychological influences the yield, creating conditions required to use the most of natural resources.Sociometric test is considered as main instrument and the point of departure of the knowledge of various aspects of the process of interaction that occurs as a collective, offering only raw material in connection with the professional athlete and relational aspects of the group as a whole.The purpose of research is represented by the identification interpersonal relations team sports games, as well as the possibilities in the improvement of their capacity in order to increase performance in general and in particular of the handball boys team Stiinta Municipal Bacau. At the inclusion in the sample of subjects, they were aged between 19 and 34 years of age and a seniority in practicing sport performance from 6 to 10 years. A conclusion that we can detach from the situation presented, it would be that even though they are players of basic team, it would seem that, in key moments of the game, the preferences of collaboration between them do not coincide with team composition in the same situations, that may cause negative effects in the course of carrying out the game and, by default, in attaining the desired results.

  6. International Space Station (ISS) Internal Active Thermal Control System (IATCS) New Biocide Selection, Qualification and Implementation

    Wilson, Mark E.; Cole, Harold E.; Rector, Tony; Steele, John; Varsik, Jerry

    2011-01-01

    The Internal Active Thermal Control System (IATCS) aboard the International Space Station (ISS) is primarily responsible for the removal of heat loads from payload and system racks. The IATCS is a water based system which works in conjunction with the EATCS (External ATCS), an ammonia based system, which are interfaced through a heat exchanger to facilitate heat transfer. On-orbit issues associated with the aqueous coolant chemistry began to occur with unexpected increases in CO2 levels in the cabin. This caused an increase in total inorganic carbon (TIC), a reduction in coolant pH, increased corrosion, and precipitation of nickel phosphate. These chemical changes were also accompanied by the growth of heterotrophic bacteria that increased risk to the system and could potentially impact crew health and safety. Studies were conducted to select a biocide to control microbial growth in the system based on requirements for disinfection at low chemical concentration (effectiveness), solubility and stability, material compatibility, low toxicity to humans, compatibility with vehicle environmental control and life support systems (ECLSS), ease of application, rapid on-orbit measurement, and removal capability. Based on these requirements, ortho-phthalaldehyde (OPA), an aromatic dialdehyde compound, was selected for qualification testing. This paper presents the OPA qualification test results, development of hardware and methodology to safely apply OPA to the system, development of a means to remove OPA, development of a rapid colorimetric test for measurement of OPA, and the OPA on-orbit performance for controlling the growth of microorganisms in the ISS IATCS since November 3, 2007.

  7. Developing Science Communication in Africa: Undergraduate and Graduate Students should be Trained and Actively Involved in Outreach Activity Development and Implementation

    Karikari, Thomas K.; Yawson, Nat Ato; Quansah, Emmanuel

    2016-01-01

    Despite recent improvements in scientific research output from Africa, public understanding of science in many parts of the continent remains low. Science communication there is faced with challenges such as (i) lack of interest among some scientists, (ii) low availability of training programs for scientists, (iii) low literacy rates among the public, and (iv) multiplicity of languages. To address these challenges, new ways of training and motivating scientists to dialogue with non-scientists are essential. Developing communication skills early in researchers’ scientific career would be a good way to enhance their public engagement abilities. Therefore, a potentially effective means to develop science communication in Africa would be to actively involve trainee scientists (i.e., undergraduate and graduate students) in outreach activity development and delivery. These students are often enthusiastic about science, eager to develop their teaching and communication skills, and can be good mentors to younger students. Involving them in all aspects of outreach activity is, therefore, likely to be a productive implementation strategy. However, science communication training specifically for students and the involvement of these students in outreach activity design and delivery are lacking in Africa. Here, we argue that improving the training and involvement of budding scientists in science communication activities would be a good way to bridge the wide gap between scientists and the African public.

  9. The Joint NEA/IAEA Uranium Group -- its role in assessing world uranium resources, production, demand and environmental activities and issues

    In 1965 a 20-page report entitled World Uranium and Thorium Resources was published by the OECD-European Nuclear Energy Agency. Today, 35 years later, the report is jointly prepared by the OECD/Nuclear Energy Agency and the IAEA and published by the OECD. The report: Uranium Resources, Production and Demand also known as the Red Book is in its 18th edition. It is the only official publication on world uranium statistics and provides information from 45 or more countries. One aim of the Red Book is to obtain a uniform, worldwide acceptable classification of uranium resources. The Red Book provides statistics and analyses for resources, exploration, production, demand, secondary sources, surplus defence material and the supply and demand relationship. The sales records indicate that it is used as reference material for various purposes including public and private libraries, energy companies, uranium production companies, national and international organisation, universities and other research and business institutions. In 1996 a study was started which led to the 1999 report: Environmental Activities in Uranium Mining and Milling, a companion to the Red Book. This complementary report provides information on the site characterization, dismantling and decommissioning, waste management, water remediation, long term monitoring policies and regulations for 29 countries. A second report entitled 'Environmental Remediation of Uranium Production Facilities' is being prepared. (author)

  10. Microstructural characterization of a diffusion-bonded joint for 9Cr-ODS and JLF-1 reduced activation ferritic/martensitic steels

    Bonding of oxide dispersion strengthened (ODS) steels to non-ODS reduced activation ferritic/martensitic (RAFM) steels is essential to their application to blanket systems. In the present study, a diffusion-bonded joint of the candidate 9Cr-ODS steel and JLF-1 RAFM steel was fabricated using hot isostatic pressing (HIP). The effect of post-bond heat treatments (PBHTs) was studied by hardness measurement and microstructural analysis. The results indicated that, after normalization and tempering (N and T), the hardness and microstructures of 9Cr-ODS and JLF-1 base metals recovered to levels similar to those before HIP. However, a soft region was observed across the bonding interfaces for all specimens containing the as-HIPed condition and those after PBHTs. This was due to coarser micro-carbides (M3C in as-HIPed condition and M23C6 in N and T conditions) near the interfaces than in the base metals for both 9Cr-ODS and JLF-1. Energy Dispersive X-ray Spectroscopy (EDS) analysis confirmed that carbon, tungsten, and chromium in the matrix near the interfaces are transferred to the micro-carbides, making them coarser there. Ti diffused from the 9Cr-ODS side to the JLF-1 side forming Ti-rich carbides after tempering, especially at high temperature to 1073 K

  11. Butt Joint Tool Commissioning

    Martovetsky, N N

    2007-12-06

    ITER Central Solenoid uses butt joints for connecting the pancakes in the CS module. The principles of the butt joining of the CICC were developed by the JAPT during CSMC project. The difference between the CSMC butt joint and the CS butt joint is that the CS butt joint is an in-line joint, while the CSMC is a double joint through a hairpin jumper. The CS butt joint has to carry the hoop load. The straight length of the joint is only 320 mm, and the vacuum chamber around the joint has to have a split in the clamp shell. These requirements are challenging. Fig.1 presents a CSMC joint, and Fig.2 shows a CS butt joint. The butt joint procedure was verified and demonstrated. The tool is capable of achieving all specified parameters. The vacuum in the end was a little higher than the target, which is not critical and readily correctable. We consider, tentatively that the procedure is established. Unexpectedly, we discover significant temperature nonuniformity in the joint cross section, which is not formally a violation of the specs, but is a point of concern. All testing parameters are recorded for QA purposes. We plan to modify the butt joining tool to improve its convenience of operation and provide all features necessary for production of butt joints by qualified personnel.

  12. The implementation of risk management in adventurous activities in Greece: The «Trekking Hellas» company

    2006-01-01

    Full Text Available Adventurous activities can be both beneficial and perilous for health, because the circumstances differ and because of external and not always controllable factors, which may influence the outcomes. Therefore, any company, which organises adventurous activities, needs to present effective risk management and valuable safety measures in order to respond to its participants’ safety and satisfaction. This study, which was performed in the Greek company «Trekking Hellas», aimed at asserting the importance of risk management for adventure tourism. The data that were collected through personal, semi – structured interviews with the company’s managers and participants have shown that the particular company has made notable attempts to establish an organised and well-controlled risk management. This has been accomplished through implementing a methodical risk assessment and operating all necessary safety measures. The research, also, discussed the influence that the above might have had on the clients’ motivation for participation. Finally, the data have pointed out the significance that risk management has for the success of every activity and in extent, for the success and promotion of the company.

    2006-02-01

    Full Text Available Abstract Background Powered lower limb orthoses could reduce therapist labor during gait rehabilitation after neurological injury. However, it is not clear how patients respond to powered assistance during stepping. Patients might allow the orthoses to drive the movement pattern and reduce their muscle activation. The goal of this study was to test the effects of robotic assistance in subjects with incomplete spinal cord injury using pneumatically powered ankle-foot orthoses. Methods Five individuals with chronic incomplete spinal cord injury (ASIA C-D participated in the study. Each subject was fitted with bilateral ankle-foot orthoses equipped with artificial pneumatic muscles to power ankle plantar flexion. Subjects walked on a treadmill with partial bodyweight support at four speeds (0.36, 0.54, 0.72 and 0.89 m/s under three conditions: without wearing orthoses, wearing orthoses unpowered (passively, and wearing orthoses activated under pushbutton control by a physical therapist. Subjects also attempted a fourth condition wearing orthoses activated under pushbutton control by them. We measured joint angles, electromyography, and orthoses torque assistance. Results A therapist quickly learned to activate the artificial pneumatic muscles using the pushbuttons with the appropriate amplitude and timing. The powered orthoses provided ~50% of peak ankle torque. Ankle angle at stance push-off increased when subjects walked with powered orthoses versus when they walked with passive-orthoses (ANOVA, p Two of the five subjects were able to control the orthoses themselves using the pushbuttons. The other three subjects found it too difficult to coordinate pushbutton timing. Orthoses assistance and maximum ankle angle at push-off were smaller when the subject controlled the orthoses compared to when the therapist-controlled the orthoses (p Conclusion Mechanical assistance from powered ankle-foot orthoses improved ankle push-off kinematics without

  15. Elevated sacroilac joint uptake ratios in systemic lupus erythematosus

    Sacroiliac joint radiographs and radionuclide sacroiliac joint uptake ratios were obtained on 14 patients with active systemic lupus erythematosus. Elevated joint ratios were found unilaterally in two patients and bilaterally in seven patients when their lupus was active. In patients whose disease became quiescent, the uptake ratios returned to normal. Two patients had persistently elevated ratios with continued clinical and laboratory evidence of active lupus. Mild sacroiliac joint sclerosis and erosions were detected on pelvic radiographs in these same two patients. Elevated quantitative sacroiliac joint uptake ratios may occur as a manifestation of active systemic lupus erythematosus

  16. Indigenous teachers' experiences of the implementation of culture-based mathematics activities in Sámi school

    Nutti, Ylva Jannok

    2013-03-01

    The goal of Indigenous education is that it should be approached on the basis of the Indigenous language and culture; this is also the case with Sámi education. The Sámi School Board has stated that all teaching in Sámi schools should be culturally based, despite the fact that Sámi culture-based teaching is not specifically defined. Therefore, teachers themselves must adapt the teaching and as a result, usually no Sámi culture-based mathematics teaching takes place. The aim of this article is to discuss Indigenous teachers' experiences with designing and implementing culture-based mathematics activities in Sámi preschool and primary school. The teachers' work with culture-based mathematics activities took the form of Sámi cultural thematic work with ethnomathematical content, Multicultural school mathematics with Sámi cultural elements, and Sámi intercultural mathematics teaching. Culture-based mathematics activities took place within an action research study in the Swedish part of Sápmi. Sápmi comprises northern Norway, Sweden, and Finland, as well as the Kola Peninsula in Russia. In the action research study, six teachers conducted culture-based mathematics activities in preschool and primary school on the basis of the action research loop "plan-act-observe-reflect." During the study the teachers changed from a problem-focused perspective to a possibility-focused culture-based teaching perspective characterised by a self-empowered Indigenous teacher role, as a result of which they started to act as agents for Indigenous school change. The concept of "decolonisation" was visible in the teachers' narratives. The teachers' newly developed knowledge about the ethnomathematical research field seemed to enhance their work with Indigenous culture-based mathematics teaching.

  17. Barriers and facilitators for the implementation of primary prevention and health promotion activities in primary care: a synthesis through meta-ethnography.

    Maria Rubio-Valera

    Full Text Available BACKGROUND: Evidence supports the implementation of primary prevention and health promotion (PP&HP activities but primary care (PC professionals show resistance to implementing these activities. The aim was to synthesize the available qualitative research on barriers and facilitators identified by PC physicians and nurses in the implementation of PP&HP in adults. METHODS AND FINDINGS: A systematic search of three databases was conducted and supported by manual searches. The 35 articles included were translated into each other and a new interpretation of the concepts extracted was generated. The factors affecting the implementation of PP&HP activities in PC according to professionals were fitted into a five-level ecological model: intrapersonal factors, interpersonal processes, institutional factors, community factors and public policy. At the intrapersonal level we find professionals' beliefs about PP&HP, experiences, skills and knowledge, and selfconcept. The attitudes and behavior towards PP&HP of patients, specialists, practice managers and colleagues (interpersonal factors affect the feasibility of implementing PP&HP. Institutional level: PC is perceived as well-placed to implement PP&HP but workload, lack of time and referral resources, and the predominance of the biomedical model (which prioritizes disease treatment hamper the implementation of PP&HP. The effectiveness of financial incentives and tools such as guidelines and alarms/reminders is conditioned by professionals' attitudes to them. Community factors include patients' social and cultural characteristics (religion, financial resources, etc., local referral resources, mass-media messages and pharmaceutical industry campaigns, and the importance given to PP&HP in the curriculum in university. Finally, policies affect the distribution of resources, thus affecting the implementation of PP&HP. CONCLUSIONS: Research on barriers and facilitators in the implementation of PP&HP activities

  2. Implementation of an active aging model in Mexico for prevention and control of chronic diseases in the elderly

    Correa-Muñoz Elsa

    2009-08-01

    Full Text Available Abstract Background World Health Organization cites among the main challenges of populational aging the dual disease burden: the greater risk of disability, and the need for care. In this sense, the most frequent chronic diseases during old age worldwide are high blood pressure, type 2 diabetes mellitus, cancer, arthritis, osteoporosis, depression, and dementia. Chronic disease-associated dependency represents an onerous sanitary and financial burden for the older adult, the family, and the health care system. Thus, it is necessary to propose community-level models for chronic disease prevention and control in old age. The aim of the present work is to show our experience in the development and implementation of a model for chronic disease prevention and control in old age at the community level under the active aging paradigm. Methods/Design A longitudinal study will be carried out in a sample of 400 elderly urban and rural-dwelling individuals residing in Hidalgo State, Mexico during five years. All participants will be enrolled in the model active aging. This establishes the formation of 40 gerontological promoters (GPs from among the older adults themselves. The GPs function as mutual-help group coordinators (gerontological nuclei and establish self-care and self-promotion actions for elderly well-being and social development. It will be conformed a big-net of social network of 40 mutual-help groups of ten elderly adults each one, in which self-care is a daily practice for chronic disease prevention and control, as well as for achieving maximal well-being and life quality in old age. Indicators of the model's impact will be (i therapeutic adherence; (ii the incidence of the main chronic diseases in old age; (iii life expectancy without chronic diseases at 60 years of age; (iv disability adjusted life years lost; (v years of life lost due to premature mortality, and (vi years lived with disability.

  4. The use of parent involved take-home science activities during student teaching: Understanding the challenges of implementation

    Zarazinski, Jill

    The purpose of this study was to identify student teachers use and implementation of Science in a Bag when it was no longer a required course-based assessment. This take-home science activity acted as the elaboration component of the 5Es lesson teacher candidates designed and taught in the classroom, utilized household items, and directly involved parents in their child's education. The purposeful sample was comprised of six teacher candidates during their student teaching practicum, the last semester of the childhood education teacher certification program. This collective case study centered on student teachers' use of the focused activity, Science in a Bag, in order to gain knowledge of challenges faced in applying take-home science kits and working with parents. Data collection was comprised of student teacher and parent interviews, candidate reflections, as well as in-class observations and discussions carried out during weekly seminars. Data collection occurred throughout the seven-week student teaching practicum. The four research questions were: 1) What factors do teacher candidates identify as interfering with their ability to implement Science in a Bag during student teaching placements? 2) What factors do teacher candidates identify as enhancing their ability to carry out Science in a Bag? 3) What forms of support do teacher candidates believe are important to their success in implementing Science in a Bag during student teaching? 4) How do teacher candidates deal with obstacles when implementing Science in a Bag? Despite the fact that no student teacher was prohibited from implementing Science in a Bag, the level to which candidates valued and utilized this instructional strategy varied compared to how they were taught and practiced it during the science methods course. Some student teachers attempted to hide their feelings toward Science in a Bag, however their actions revealed that they were simply carrying out the instructional strategy because they

  5. Detection of Arthritis by Joint Scanning

    Detection and identification of early arthritis is frequently difficult with routine methods. Several tracers, 131I human serum albumin (25 μCi/10 lb), 99mTc human serum albumin (1-3 mCi), 131I iodipamide (40 μCi/10 lb), and 99mTc pertechnetate (10 mCi), have been employed for joint scanning to detect synovitis produced by arthritis in joints of the extremities. When administered intravenously, the 25% increase in localization of these tracers in the synovial membrane, if there is active synovitis, can be demonstrated by scintillation scanning. This ability to detect synovitis at an early stage enables the joint scan to show areas of active synovitis not demonstrated on roentgenograms. The scan may objectively confirm or disprove questionable physical findings. From this standpoint the technique has been useful in determining whether joint pain is functional or due to arthritis as a negative localization tends to rule out active synovitis as the cause of the pain. The scan demonstration of a positive localization of the tracer in several joints when only one area is symptomatic is evidence that joint pain is due to systemic disease. The short half-life tracera permit serial studies to follow the course of an arthritis process. Use of 99mTc pertechnetate and an Anger camera have made joint scanning a practical technique for clinical use. A review of the accuracy of joint scanning in 130 cases as compared to roentgenograms is presented. (author)

  6. The effects of environmental parameters on diffuse degassing at Stromboli volcano: Insights from joint monitoring of soil CO2 flux and radon activity

    2016-04-01

    Soil CO2 flux and 222Rn activity measurements may positively contribute to the geochemical monitoring of active volcanoes. The influence of several environmental parameters on the gas signals has been substantially demonstrated. Therefore, the implementation of tools capable of removing (or minimising) the contribution of the atmospheric effects from the acquired time series is a challenge in volcano surveillance. Here, we present 4 years-long continuous monitoring (from April 2007 to September 2011) of radon activity and soil CO2 flux collected on the NE flank of Stromboli volcano. Both gases record higher emissions during fall-winter (up to 2700 Bq * m- 3 for radon and 750 g m- 2 day- 1 for CO2) than during spring-summer seasons. Short-time variations on 222Rn activity are modulated by changes in soil humidity (rainfall), and changes in soil CO2 flux that may be ascribed to variations in wind speed and direction. The spectral analyses reveal diurnal and semi-diurnal cycles on both gases, outlining that atmospheric variations are capable to modify the gas release rate from the soil. The long-term soil CO2 flux shows a slow decreasing trend, not visible in 222Rn activity, suggesting a possible difference in the source depth of the of the gases, CO2 being deeper and likely related to degassing at depth of the magma batch involved in the February-April 2007 effusive eruption. To minimise the effect of the environmental parameters on the 222Rn concentrations and soil CO2 fluxes, two different statistical treatments were applied: the Multiple Linear Regression (MLR) and the Principal Component Regression (PCR). These approaches allow to quantify the weight of each environmental factor on the two gas species and show a strong influence of some parameters on the gas transfer processes through soils. The residual values of radon and CO2 flux, i.e. the values obtained after correction for the environmental influence, were then compared with the eruptive episodes that

  10. Joint Degree Program: the Perspective of Employers

    Tatjana Bilevičienė

    2013-08-01

    Full Text Available Purpose — the purpose of this article is to extend discussion towards the need and importance of joint degree programs in modern universities, introducing the perspective of the employers toward this question. Design/methodology/approach — the research was conducted to analyze the demand of joint degree programs from the perspective of employers, identify weak and strong aspects, opinion and demand for graduates of such programs. To achieve this purpose, a combination of theoretical and empirical methods was chosen: document analysis (previous studies, statistics was conducted and an online qualitative survey was organized. Findings — The analysis of articles, studies and statistics points out the challenges and threats faced by universities nowadays, forcing higher education institutions to find new ways to raise the quality of studies and raise the interest of employers to choose graduates from MRU, as well as the satisfaction of employers with their choice of employees. Theoretical analysis pointed out these challenges and requirements for the modern employee, summarised the challenges in preparation of IT field specialists. The conducted research results showed that the diploma of joint degree programs would not be treated as an advantage of possible employee from the perspective of employers in case some important aspects will not be taken into consideration by program creators. On the other hand, undeniably there are strong sides, such as knowledge in the fields of foreign language, international experience, innovativeness and creativeness of employees that would be treated as an advantage in the process of selection for positions of any technical support related positions. Research limitations/implications — employers, whose business activities are closely related to information technology, have been invited as experts.

Conclusion: DCE-MRI provides fast and accurate assessment of synovial inflammation in RA patients. Manual outlining of the joint to...

  12. Joint action without and beyond planning

    Blomberg, Olle

    2013-01-01

    Leading philosophical accounts of joint activity, such as Michael Bratman’s account of ‘shared intentional activity’, take joint activity to be the outcome of two or more agents having a ‘shared intention’, where this is a certain pattern of mutually known prior intentions (plans) that are directed...... toward a common goal. With Bratman’s account as a foil, I address two lacunas that are relatively unexplored in the philosophical literature. The first lacuna concerns how to make sense of the apparently joint cooperative activities of agents that lack the capacities for planning and “mindreading” that...... “online”—that is, during action execution as a joint activity unfolds—without recourse to plans that specify in advance what they should do (consider the coordination involved when two friends meet and do a “high five”). Chapters 2 and 3 focus on the first lacuna, while chapters 4 and 5 focus on the...

  13. Estimation of Joint types and Joint Limits from Motion capture data

    Engell-Nørregård, Morten Pol; Erleben, Kenny

    2009-01-01

    It is time-consuming for an animator to explicitly model joint types and joint limits of articulated figures. In this paper we describe a simple and fast approach to automated joint estimation from motion capture data of articulated figures. Our method will make the joint modeling more efficient...... and less time consuming for the animator by providing a good starting estimate that can be fine-tuned or extended by the animator if she wishes, without restricting her artistic freedom. Our method is simple, easy to implement and specific for the types of articulated figures used in interactive animation...... such as computer games. Other work for joint limit modeling consider more complex and general purpose models. However, these are not immediately suitable for inverse kinematics skeletons used in interactive applications....

  14. Attention, Joint Attention, and Social Cognition

    Mundy, Peter; Newell, Lisa

    2007-01-01

    Before social cognition there is joint processing of information about the attention of self and others. This joint attention requires the integrated activation of a distributed cortical network involving the anterior and posterior attention systems. In infancy, practice with the integrated activation of this distributed attention network is a major contributor to the development of social cognition. Thus, the functional neuroanatomies of social cognition and the anterior–posterior attention ...

  15. Research and development activities of the Joint Research Centre -JRC and its involvement in the development of future nuclear energy systems

    Besides the policy driven support which the JRC gives to the European Commission and its Member States, the nuclear activities of the JRC also fulfil the Research and Development obligations as enshrined in the EURATOM Treaty. These have for objectives to develop and assemble knowledge in the field of nuclear energy and concern basic actinide research, nuclear data and nuclear measurements, radiation monitoring and radionuclides in the environment, health and nuclear medicine, management of spent fuel and waste, safety of reactors and fuel cycle and nuclear safeguards and non proliferation. The European Union currently imports 50% of its energy and, going by the present trend, this may increase to 70% within 20 years. One third of the electricity in Europe is currently been produced via nuclear fission and the move to innovative reactor systems holds great promise. In May 2006, the European Atomic Energy Community became a Party to the Framework Agreement for International Collaboration on Research and Development of Generation IV Nuclear Energy Systems (GIF Framework Agreement). The 'Generation IV' initiative concerns concepts for nuclear energy systems that can be operated in a manner that will provide a competitive and reliable supply of energy, while satisfactorily addressing nuclear safety, waste, proliferation and public perception concerns. The JRC with its strong international dimension is not only the implementing agent for EURATOM in the Generation IV international forum, but also participates actively in related Research and Development projects. The Research and Development projects are focused on fuel development, reprocessing and irradiation testing, fuel cladding interaction and corrosion, basic data for fuel and reprocessing, reprocessing and waste treatment. In this paper the Research and Development the nuclear activities of the JRC will be presented especially those related to its participation to GIF

  16. A field exercise course to train IAEA Safeguards inspectors in implementing the additional protocol and performing complementary access activities

    The International Atomic Energy Agency (IAEA) Department of Safeguards has the task of implementing the Additional Protocol (AP) in the Member States that have signed agreements bringing that treaty into force. The IAEA inspector under the traditional INFCIRC/153 safeguards has been an accountant focused on the declared nuclear material stores of a Member State. The INFCIRC/540 Strengthened Safeguards System (SSS) provides the Agency and its inspectors with the right to investigate a Member State's nuclear programme to see if all declared activities are in order and no undeclared activities exist. This broadening of the scope of the inspector's responsibilities has changed the training of the inspectors to orient them to being an investigator compared to an accountant. The Safeguards training department has created a curriculum of courses that provides the background to train the inspectorate into this new inspection regime. The United States Support Program (USSP) has contributed to this curriculum by putting together a course at Brookhaven National Laboratory (BNL) in Additional Protocol Complementary Access (APCA) to give the IAEA the opportunity to provide inspectors a necessary field exercise in a realistic environment at a research site. Brookhaven National Laboratory contains three shutdown nuclear research reactors, operating particle accelerators, hot cells, radioactive waste storage, laser laboratories, and magnet production facilities on a large site very similar to numerous research facilities around the world situated in non-nuclear weapon states (NNWS). The USSP Team created an Article 2 declaration containing annotated maps of the site, descriptions of the buildings on site, satellite and aerial photographs of the area, and a declaration of research activities on the site. The declaration is as realistic to actual BNL research except that proprietary and security concerns of the BNL site have been taken into account. The USSP Team felt the best

  17. Active Metal Brazing and Characterization of Brazed Joints in C-C and C-SiC Composites to Copper-Clad-Molybdenum System

    Singh, M.; Asthana, R.

    2008-01-01

    Carbon/carbon composites with CVI and resin-derived matrices, and C/SiC composites reinforced with T-300 carbon fibers in a CVI SiC matrix were joined to Cu-clad Mo using two Ag-Cu braze alloys, Cusil-ABA (1.75% Ti) and Ticusil (4.5% Ti). The brazed joints revealed good interfacial bonding, preferential precipitation of Ti at the composite/braze interface, and a tendency toward delamination in resin-derived C/C composite. Extensive braze penetration of the inter-fiber channels in the CVI C/C composites was observed. The Knoop microhardness (HK) distribution across the C/C joints indicated sharp gradients at the interface, and a higher hardness in Ticusil than in Cusil-ABA. For the C/SiC composite to Cu-clad-Mo joints, the effect of composite surface preparation revealed that ground samples did not crack whereas unground samples cracked. Calculated strain energy in brazed joints in both systems is comparable to the strain energy in a number of other ceramic/metal systems. Theoretical predictions of the effective thermal resistance suggest that such joined systems may be promising for thermal management applications.

  18. Progressive Damage Analysis of Bonded Composite Joints

    Leone, Frank A., Jr.; Girolamo, Donato; Davila, Carlos G.

    2012-01-01

    The present work is related to the development and application of progressive damage modeling techniques to bonded joint technology. The joint designs studied in this work include a conventional composite splice joint and a NASA-patented durable redundant joint. Both designs involve honeycomb sandwich structures with carbon/epoxy facesheets joined using adhesively bonded doublers.Progressive damage modeling allows for the prediction of the initiation and evolution of damage within a structure. For structures that include multiple material systems, such as the joint designs under consideration, the number of potential failure mechanisms that must be accounted for drastically increases the complexity of the analyses. Potential failure mechanisms include fiber fracture, intraply matrix cracking, delamination, core crushing, adhesive failure, and their interactions. The bonded joints were modeled using highly parametric, explicitly solved finite element models, with damage modeling implemented via custom user-written subroutines. Each ply was discretely meshed using three-dimensional solid elements. Layers of cohesive elements were included between each ply to account for the possibility of delaminations and were used to model the adhesive layers forming the joint. Good correlation with experimental results was achieved both in terms of load-displacement history and the predicted failure mechanism(s).
