  1. Global Health as a Field of Power Relations: A Response to Recent Commentaries.

    Shiffman, Jeremy

    2015-05-22

    Actors working in global health often portray it as an enterprise grounded in principled concerns, advanced by individuals and organizations who draw on scientific evidence to pursue health equity. This portrait is incomplete. It is also a field of power relations-a social arena in which actors claim and draw on expertise and moral authority to gain influence and pursue career, organizational and national interests. A clear understanding of how power operates in this field is necessary to ensure that it is used productively to serve the aims of health equity and improved population health. Responding to commentaries on an editorial published in this journal, I offer 3 ideas toward this end: (1) be skeptical of the global health rationality project-the effort to rescue the field from the alleged indignities of politics through the application of scientific methods; (2) analyze global health as a field of power relations, a concept developed by sociologist Pierre Bourdieu; and (3) elevate the place of input legitimacy-inclusive deliberation, fair process and transparency-to address legitimacy and knowledge deficits in this field. © 2015 by Kerman University of Medical Sciences.

  3. Global development of advanced nuclear power plants, and related IAEA activities

    2006-09-01

    Renewed interest in the potential of nuclear energy to contribute to a sustainable worldwide energy mix is underlining the IAEA's statutory role in fostering the peaceful uses of nuclear energy, in particular the need for effective exchanges of information and collaborative research and technology development among Member States on advanced nuclear power technologies deployable in the near term as well as in the longer term. For applications in the medium to longer term, with rising expectations for the role of nuclear energy in the future, technological innovation has become a strong focus of nuclear power technology developments by many Member States. To meet Member States' needs, the IAEA conducts activities to foster information exchange and collaborative research and development in the area of advanced nuclear reactor technologies. These activities include coordination of collaborative research, organization of international information exchange, and analyses of globally available technical data and results, with a focus on reducing nuclear power plant capital costs and construction periods while further improving performance, safety and proliferation resistance. In other activities, evolutionary and innovative advances are catalyzed for all reactor lines such as advanced water cooled reactors, high temperature gas cooled reactors, liquid metal cooled reactors and accelerator driven systems, including small and medium sized reactors. In addition, there are activities related to other applications of nuclear energy such as seawater desalination, hydrogen production, and other process heat applications. This brochure summarizes the worldwide status and the activities related to advanced nuclear power technology development and related IAEA activities. It includes a list of the collaborative research and development projects conducted by the IAEA, as well as of the status reports and other publications produced

  4. Global power: Markets and strategies

    Poirer, J.L.

    1998-01-01

    The author will first present an updated view of the global power market activity, including opportunities in power generation, transmission and distribution. This will include a review of the trends in closings and transaction flowed by type of activity and geographic area. Estimates will be based on Hagler Bailly's comprehensive database on global power transactions and project announcements. The firm has also worked with dozens of global power companies since 1990. Second, the author will review trends in terms of regulatory changes, project cost trends, developers' project experiences, and financing issues. This systematic review will be the foundation for projection of future market activity (e.g., number of closing by type of project through 2000). A forecast of future greenfield and privatization activity will be provided and the key markets will be highlighted. Third, the author will present an updated view of the competition in the global power market (including the various types of competitors and changes in their respective market posture). Finally, the author will discuss the various types of strategies and business models that are followed by key global power players

    Southworth, F.H.

    2010-01-01

    'Full text:' The global nuclear power forecast, the North American outlook and the effect of nuclear power growth on greenhouse gas emissions in North America will be discussed. The construction of Generation III reactors will replace aging power plants and, further, add capacity that is environmentally sustainable. The outlook for Generation IV reactors also may significantly improve the environmental balance after 2030, both in electrical markets, waste reduction, and in non-traditional markets such as process heat.

  6. Global general relativity

    Penrose, R.

    1979-01-01

    Much theoretical work in General Relativity has been concerned with finding explicit solutions of Einstein field equations. Exact solutions must involve simplifying procedures which in the case of strong gravitational fields may not be valid. Computers can help but complementary to these are the global qualitative mathematics that have been introduced into relativity over the past years. These have shown that Einstein's equations together with suitable inequalities on the energy-momentum tensor can lead inevitably to space-time singularities arising, provided that some qualitative geometric criterion is satisfied. It seems that in suitable situations of gravitational collapse this criterion will be satisfied. Similarly in a cosmological setting the criterion can be applied in the reverse direction in time. There is, however, the unsolved problem in general relativity of cosmic censorship and this is discussed as a consequence of Einstein's equations. (UK)

  7. Electric power globalization and reforming

    Soares Neto, Jose Lino

    1999-01-01

    The central issue of debate was the need to align the energy sector's options and organization with changing global patterns of economic and social development, characterized by the increasing role played by the private sector, greater integration in the world economy, and new economic and social priorities such as efficiency, decentralization, deregulation, and a closer attention to environmental issues. The aim of the work was to define the economic and political forces of the electric power sector regulation restructuring

  8. Can global warming save nuclear power?

    Pearce, D.

    1994-01-01

    Nuclear powered electricity generation in the United Kingdom has an uncertain future. The relative costs of generating electricity by nuclear fission compared to other means and the need for a desirable mixture or ''portfolio'' of energy sources in the electricity industry are identified as the key to this uncertainty. The author argues that Government commitments to reducing Carbon Monoxide (CO) emissions, and hence global warming, may strengthen arguments in favour of a firm commitment to nuclear power, as even modern fossil-fuelled power plants emit nearly 90 times as much CO as nuclear plants. (UK)

  9. Global warming and nuclear power

    Wood, L., LLNL

    1998-07-10

    Nuclear fission power reactors represent a potential solution to many aspects of global change possibly induced by inputting of either particulate or carbon or sulfur oxides into the Earth`s atmosphere. Of proven technological feasibility, they presently produce high-grade heat for large-scale electricity generation, space heating and industrial process-energizing around the world, without emitting greenhouse gases or atmospheric particulates; importantly, electricity production costs from the best nuclear plants presently are closely comparable with those of the best fossil-fired plants. However, a substantial number of issues currently stand between nuclear power and widespread substitution for large stationary fossil fuel-fired systems. These include perceptual ones regarding both long-term and acute operational safety, plant decommissioning, fuel reprocessing, radwaste disposal, fissile materials diversion to military purposes and - perhaps most seriously- readily quantifiable concerns regarding long-term fuel supply and total unit electrical energy cost. We sketch a road-map for proceeding from the present situation toward a nuclear power-intensive world, addressing along the way each of the concerns which presently impede widespread nuclear substitution for fossil fuels, particularly for coal in the most populous and rapidly developing portions of the world, e.g., China and India. This `design to societal specifications` approach to large-scale nuclear fission power systems may lead to energy sources meeting essentially all stationary demands for high-temperature heat. Such advanced options offer a human population of ten billion the electricity supply levels currently enjoyed by Americans for 10,000 years. Nuclear power systems tailored to local needs-and-interests and having a common advanced technology base could reduce present-day world-wide C0{sub 2} emissions by two-fold, if universally employed. By application to small mobile demands, a second two

  10. Global warming and nuclear power

    Hodgson, P.E. [Nuclear and Particle Physics Laboratory, Department of Physics, Oxford Univ., Oxford (United Kingdom)

    1999-09-01

    The concentration of carbon dioxide in the atmosphere is steadily increasing and it is widely believed that this will lead to global warming that will have serious consequences for life on earth. The Intergovernmental Panel on Climate Change has estimated that the temperature of the earth will increase by between 1 and 3.5 degrees in the next century. This will melt some of the Antarctic ice cap, raise the sea level and flood many low-lying countries, and also produce unpredictable changes in the earth's climate. The possible ways of reducing carbon dioxide emission are discussed. It is essential to reduce the burning of fossil fuels, but then how are we to obtain the energy we need? We can try to reduce energy use, but we will still need to generate large amounts energy. Some possible ways of doing this are by using wind and solar generators, by hydroelectric and tidal plants, and also by nuclear power. These possibilities will be critically examined. (author)

  12. Nuclear power generation and global heating

    Taboada, Horacio

    1999-01-01

    The Professionals Association and Nuclear Activity of National Atomic Energy Commission (CNEA) are following with great interest the worldwide discussions on global heating and the role that nuclear power is going to play. The Association has an active presence, as part of the WONUC (recognized by the United Nations as a Non-Governmental Organization) in the COP4, which was held in Buenos Aires in November 1998. The environmental problems are closely related to human development, the way of power production, the techniques for industrial production and exploitation fields. CO 2 is the most important gas with hothouse effects, responsible of progressive climatic changes, as floods, desertification, increase of average global temperature, thermal expansion in seas and even polar casks melting and ice falls. The consequences that global heating will have on the life and economy of human society cannot be sufficiently emphasized, great economical impact, destruction of ecosystems, loss of great coast areas and complete disappearance of islands owing to water level rise. The increase of power retained in the atmosphere generates more violent hurricanes and storms. In this work, the topics presented in the former AATN Meeting is analyzed in detail and different technological options and perspectives to mitigate CO 2 emission, as well as economical-financial aspects, are explored.

  13. Global warming and nuclear power

    Hodgson, P.E.

    1999-01-01

    The problems of pollution, global warming and renewable energy sources are not going to go away. Governments need to act with urgency if they are to produce a long-term energy policy. This paper looks at the current energy situation, and how this would project into the future without the instigation of radical changes. It concludes that nuclear is the best option available for averting a growing energy, pollution and global warming crisis. (author)

  14. The challenge of market power under globalization

    David Arie Mayer-Foulkes

    2014-01-01

    The legacy of Adam Smith leads to a false confidence on the optimality of laissez faire policies for the global market economy. Instead, the polarized character of current globalization deeply affects both developed and underdeveloped economies. Current globalization is characterized by factor exchange between economies of persistently unequal development. This implies the existence of persistent extraordinary market power in transnational corporations, reflected in their disproportionate par...

  15. Global Protest Against Nuclear Power

    Kirchhof, Astrid Mignon; Meyer, Jan-Henrik

    2014-01-01

    Protest against nuclear power plants, uranium mining and nuclear testing played a pivotal role in the rise of a mass environmental movement around the globe in the 1970s and 1980s. Nevertheless, the history of anti-nuclear activism has largely been told from a strictly national perspective...... that anti-nuclear movements across the globe were transnationally connected. First, scientific expertise and protest practices were transferred between movements, and subsequently adapted to local requirements. Secondly, transnational cooperation and networks did indeed emerge, playing an important role...

  16. Knowledge, politics and power in global health

    Brown, Garrett Wallace

    2015-01-01

    This article agrees with recent arguments suggesting that normative and epistemic power is rife within global health policy and provides further examples of such. However, in doing so, it is argued that it is equally important to recognize that global health is, and always will be, deeply political and that some form of power is not only necessary for the system to advance, but also to try and control the ways in which power within that system operates. In this regard, a better focus on health politics can both expose illegitimate sources of power, but also provide better recommendations to facilitate deliberations that can, although imperfectly, help legitimate sources of influence and power.

  17. Global income related health inequalities

    Jalil Safaei

    2007-01-01

    Full Text Available Income related health inequalities have been estimated for various groups of individuals at local, state, or national levels. Almost all of theses estimates are based on individual data from sample surveys. Lack of consistent individual data worldwide has prevented estimates of international income related health inequalities. This paper uses the (population weighted aggregate data available from many countries around the world to estimate worldwide income related health inequalities. Since the intra-country inequalities are subdued by the aggregate nature of the data, the estimates would be those of the inter-country or international health inequalities. As well, the study estimates the contribution of major socioeconomic variables to the overall health inequalities. The findings of the study strongly support the existence of worldwide income related health inequalities that favor the higher income countries. Decompositions of health inequalities identify inequalities in both the level and distribution of income as the main source of health inequality along with inequalities in education and degree of urbanization as other contributing determinants. Since income related health inequalities are preventable, policies to reduce the income gaps between the poor and rich nations could greatly improve the health of hundreds of millions of people and promote global justice.

  19. Global wind power development: Economics and policies

    Timilsina, Govinda R.; Cornelis van Kooten, G.; Narbel, Patrick A.

    2013-01-01

    Existing literature indicates that theoretically, the earth's wind energy supply potential significantly exceeds global energy demand. Yet, only 2–3% of global electricity demand is currently derived from wind power despite 27% annual growth in wind generating capacity over the last 17 years. More than 95% of total current wind power capacity is installed in the developed countries plus China and India. Our analysis shows that the economic competitiveness of wind power varies at wider range across countries or locations. A climate change damage cost of US$20/tCO 2 imposed to fossil fuels would make onshore wind competitive to all fossil fuels for power generation; however, the same would not happen to offshore wind, with few exceptions, even if the damage cost is increased to US$100/tCO 2 . To overcome a large number of technical, financial, institutional, market and other barriers to wind power, many countries have employed various policy instruments, including capital subsidies, tax incentives, tradable energy certificates, feed-in tariffs, grid access guarantees and mandatory standards. Besides, climate change mitigation policies, such as the Clean Development Mechanism, have played a pivotal role in promoting wind power. Despite these policies, intermittency, the main technical constraint, could remain as the major challenge to the future growth of wind power. - Highlights: • Global wind energy potential is enormous, yet the wind energy contribution is very small. • Existing policies are boosting development of wind power. • Costs of wind energy are higher than cost of fossil-based energies. • Reasonable premiums for climate change mitigation substantially promote wind power. • Intermittency is the key challenge to future development of wind power

  20. Wind power: breakthrough to global dimensions

    Horrighs, W.

    1996-01-01

    The beginning of the 1980s saw the start of wind-turbine manufacture. Soon it had become a booming industrial sector, thanks mainly to the spirit of some young entrepreneurs and political support in many countries. But the wind-power market has assumed global dimensions and major structural changes have to be faced. (author)

  1. The development of global energy supply as a succession of energy-related innovation processes. A qualitative model approach to assess the use of nuclear power

    Herrmann, Dieter

    2017-01-01

    Often, the development of the world energy supply is adopted as a painful sequence of the exhaustible and polluting use of primary energy sources. Therefore the expectations in practically inexhaustible and environmentally neutral renewable energy sources are high. However, in fact, it depends on the available production, conversion, and utilization technology, which sources of energy are suitable to meet given demands and requirements. In particular, the development of the energy demand requires energy technology innovations to use new energy sources, to use known energy sources more efficient and to replace exhaustible energy sources at an early stage by others. The historical development of the global energy supply is a sequence of interrelated energy technology innovation processes. This makes it also possible, to analyse the historical development of nuclear power and to derive a model on the future role of nuclear power worldwide.

  2. Global warming mitigation strategies and programs for power plant developers

    Holmes, N.R.

    1992-01-01

    Power plant developers are increasingly being surprised by regulatory agencies requiring them to mitigate the carbon dioxide(CO 2 ) emissions from their proposed power plants, as part of the plant's operating permit conditions. Since carbon dioxide is not a criteria pollutant with a National Ambient Air Quality Standard, power plant developers are often troubled by this additional regulatory requirement. This presentation will describe the contribution that CO 2 makes to global warming, the role of trees and forests as carbon sequesters or sinks, some non-forestry related and forestry related mitigation programs, including the advantages, disadvantages, and some cost estimates for the forestry related CO 2 mitigation programs. As public concern about global warming continues to escalate, it is almost certain that regulatory agencies will increase their focus on CO 2 mitigation

  3. Nuclear power and the logic of globalization

    Weizsaecker, C.C. von

    2000-01-01

    The article discusses effects and results of globalization for nuclear power and other options of electricity generation. According to the present state of knowledge, it will not be possible to meet the growing worldwide energy requirement with fossil and renewable energy sources only - also because of the CO 2 problem. Consequently, nuclear power will remain an important alternative. On an international scale, this applies in particular to large countries, such as China and India, as large national economies particularly benefit from the economies of scale offered by nuclear power. This could well make Chinese nuclear technology a product for the world market. Thinking along these lines has not really gained ground in Germany, as nuclear power, being a technology requiring considerably capital outlay, is considered unsuitable for southern countries. It is an illusion to believe that Germany's opting out of the use of nuclear power could be a model to others. Instead, we are faced by the ethical question of how we can help to minimize the accident risks of nuclear facilities worldwide. We can do so only by maintaining the use of nuclear power and exporting our level of safety, for the risks will not become any smaller merely as a result of our opting out. (orig.) [de

  4. Global implications of standby power use

    Lebot, Benoit; Meier, Alan; Anglade, Alain

    2000-05-01

    Separate studies indicate that standby power is responsible for 20-60 W per home in developed countries. Standby power is responsible for about 2% of OECD countries total electricity consumption and the related power generation generates almost 1% of their carbon emissions. Replacement of existing appliances with those appliances having the lowest standby would reduce total standby power consumption by over 70%. The resulting reductions in carbon emissions would meet over 3% of OECD's total Kyoto commitments. Other strategies may cut more carbon emissions, but standby power is unique in that the reductions are best accomplished through international collaboration and whose costs and large benefits would be spread over all countries.

  5. Perspectives of the electric power industry amid the transforming global power generation markets

    Makarov, A. A.; Mitrova, T. A.; Veselov, F. V.; Galkina, A. A.; Kulagin, V. A.

    2017-10-01

    A scenario-based prognosis of the evolution of global power generation markets until 2040, which was developed using the Scaner model-and-information complex, was given. The perspective development of fuel markets, vital for the power generation industry, was considered, and an attempt to predict the demand, production, and prices of oil, gas, coal, and noncarbon resources across various regions of the world was made. The anticipated decline in the growth of the global demand for fossil fuels and their sufficiency with relatively low extraction expenses will maintain the fuel prices (the data hereinafter are given as per 2014 prices) lower than their peak values in 2012. The outrunning growth of demand for electric power is shown in comparison with other power resources by regions and large countries in the world. The conditions of interfuel competition in the electric power industry considering the changes in anticipated fuel prices and cost indicators for various power generation technologies were studied. For this purpose, the ratios of discounted costs of electric power production by new gas and coal TPPs and wind and solar power plants were estimated. It was proven that accounting the system effects (operation modes, necessary duplicating and reserving the power of electric power plants using renewable energy sources) notably reduces the competitiveness of the renewable power industry and is not always compensated by the expected lowering of its capital intensity and growth of fuel for TPPs. However, even with a moderate (in relation to other prognoses) growth of the role of power plants using renewable energy sources, they will triple electric power production. In this context, thermal power plants will preserve their leadership covering up to 60% of the global electric power production, approximately half using gas.

  6. Problem free nuclear power and global change

    Teller, E.; Wood, L.; Nuckolls, J.; Ishikawa, M.; Hyde, R.

    1997-01-01

    Nuclear fission power reactors represent a solution-in-principle to all aspects of global change possibly induced by inputting of either particulate or carbon or sulfur oxides into the Earth's atmosphere. Of proven technological feasibility, they presently produce high- grade heat for electricity generation, space heating and industrial process-driving around the world, without emitting greenhouse gases or atmospheric particulates. However, a substantial number of major issues currently stand between nuclear power implemented with light- water reactors and widespread substitution for large stationary fossil fuel-fired systems, including long-term fuel supply, adverse public perceptions regarding both long-term and acute operational safety, plant decommissioning, fuel reprocessing, radwaste disposal, fissile materials diversion to military purposes and - perhaps more seriously - cost. We describe a GW-scale, high-temperature nuclear reactor heat source that can operate with no human intervention for a few decades and that may be widely acceptable, since its safety features are simple, inexpensive and easily understood. We provide first-level details of a reactor system designed to satisfy these requirements. Such a back-solving approach to realizing large-scale nuclear fission power systems potentially leads to an energy source capable of meeting all large-scale stationary demands for high- temperature heat. If widely employed to support such demands, it could, for example, directly reduce present-day world-wide CO 2 emissions by two-fold; by using it to produce non-carbonaceous fuels for small mobile demands, a second two-fold reduction could be attained. Even the first such reduction would permit continued slow power-demand growth in the First World and rapid development of the Third World, both without any governmental suppression of fossil fuel usage

  7. Powerful Concepts in Global Health Comment on “Knowledge, Moral Claims and the Exercise of Power in Global Health”

    Eivind Engebretsen

    2015-02-01

    Full Text Available In this paper we emphasize the importance of questioning the global validity of significant concepts underpinning global health policy. This implies questioning the concept of global health as such and accepting that there is no global definition of the global. Further, we draw attention to ‘quality’ and ‘empowerment’ as examples of world-forming concepts. These concepts are exemplary for the gentle and quiet forms of power that underpin our reasoning within global health.

  8. Global movement in reviewing nuclear power generation

    Kimura, Yoshiyasu

    2007-01-01

    The price of crude oil, natural gas and coal has increased since 2004 with the rapid increase of primary energy demand in China, India and other developing countries. Moreover due to the political uncertainty in the Middle East, and the state control of energy resources in countries like Russia, the issue of energy security has become a critical issue. Nuclear power has been reconsidered in recent years in the US and European countries, because nuclear power is one of the cheapest sources of low carbon energy and also has relatively stable costs, and is thereby useful to energy security and to prevent climate change. Electricity demand is growing very rapidly in China and additional reactors are planned to give a fivefold increase in nuclear capacity to 40,000 MWe by 2020. India has a largely indigenous nuclear power program and expects to have 20,000 MWe nuclear capacity by 2020. Russia is moving steadily forward with plans for a much expanded role of nuclear energy, and the restructuring of nuclear industries has begun to strengthen competitiveness in international nuclear markets.

  9. The power of general relativity

    Clifton, Timothy; Barrow, John D.

    2005-01-01

    We study the cosmological and weak-field properties of theories of gravity derived by extending general relativity by means of a Lagrangian proportional to R 1+δ . This scale-free extension reduces to general relativity when δ→0. In order to constrain generalizations of general relativity of this power class, we analyze the behavior of the perfect-fluid Friedmann universes and isolate the physically relevant models of zero curvature. A stable matter-dominated period of evolution requires δ>0 or δ -19 assuming that Mercury follows a timelike geodesic. The combination of these observational constraints leads to the overall bound 0≤δ -19 on theories of this type

  13. Recognition of people with an opinion that nuclear power generation causes global warming

    Fukue, Chiyokazu

    2004-01-01

    Almost a half of the people are thinking that nuclear power generation causes global warming. We conducted a survey in order to explore the recognition and background for the thinking of people. Consequently, the existence of the right knowledge ''nuclear power generation does not discharge carbon dioxide at the time of power generation'' influenced most the idea which nuclear power generation prevents global warming. On the other hand, the misunderstanding as ''the radioactive material produced from a nuclear power plant advances global warming'' has influenced the idea considered as a cause, and it is though that this misunderstanding depend on the negative image to nuclear power generation. Moreover, many people do not recognize the mechanism of global warming, and it is thought that they confuse global warming with the other global environment problems, such as acid rain or ozone layer destruction. Therefore, it is required to spread the knowledge that nuclear power generation does not discharge carbon dioxide, and to promote the understanding that a radioactive material is not related to global warming. Furthermore, it is required to distinguish global warming from the other global environment problems, and to explain them intelligibly. (author)

  14. The future role of nuclear power in the global energy balance

    Semenov, B.A.; Guthrie, D.; Tatsuta, Y.

    1991-01-01

    A sound judgement on the role of nuclear power in the global energy balance within the time span of the next 30 years should logically be based on the consideration of at least a number of factors such as global trends in energy and electricity demand, practically available or estimated sources of supply, major requirements that these energy sources should meet, nuclear power's own potential, a realistic assessment of nuclear power's present status, and problems related to nuclear power. The conclusion of such an analysis is that nuclear power will retain, and may even enhance, its position as an important element in the world's energy supply mix

    Neumann, J.

    1991-01-01

    The contribution of nuclear power to satisfying the future energy needs of mankind and to alleviating the greenhouse effect problem is discussed. It is concluded that in addition to fossil fuels and the hydro-energy, nuclear power is the only macroeconomic source of energy for the majority of countries in this and the next centuries. In the first decade of the 21th century the production capacity of nuclear engineering shall roughly double, and high-temperature and fast-breeding reactors shall play an important role. It is expected that the research into nuclear fusion will progress. (Z.M.). 5 figs., 4 tabs., 8 refs

    Wheeler, John; Kagramanyan, Vladimir; Poplavskaya, Elena; Edwards, Geoffrey; Dixon, Brent; Usanov, Vladimir; Hayashi, Hideyuki; Beatty, Randall

    2011-01-01

    The INPRO collaborative project 'Global architecture of innovative nuclear energy systems based on thermal and fast reactors with the inclusion of a closed nuclear fuel cycle (GAINS)' was one of several scenario studies implemented in the IAEA in recent years. The objective of GAINS was to develop a standard framework for assessing future nuclear energy systems (NESs) taking into account sustainable development, and to validate the results through sample analyses. Belgium, Canada, China, the Czech Republic, France, India, Italy, Japan, the Republic of Korea, the Russian Federation, Slovakia, Ukraine, USA, the European Commission and Argentina as an observer participated in the project. The results received are discussed in the paper, including: development of a heterogeneous multi-group model of a global NES, estimation of nuclear energy demand, identification of a representative set of reactors and fuel cycles, evaluation capability of available analytical and modelling tools, and quantitative analysis of the different options of the global architecture. It was shown that the approach used contributes to development of a coherent vision of driving forces for nuclear energy system development and deployment. (author)

  2. POWER-SHIFTS IN THE GLOBAL ECONOMY. TRANSITION TOWARDS A MULTIPOLAR WORLD ORDER

    Ion IGNAT

    2013-12-01

    Full Text Available The paper aims to analyze the new realities and trends related to the new polarity of the global economy, and thus the reconfiguration of global power centers, a process characterized by two simultaneous trends: the rise of new powers and the relative decline of traditional powers. At the beginning of 21st century, global power is suffering two major changes: on the one hand it manifests a transition from West to East, from Atlantic to the Asia-Pacific, and on the other hand, a diffusion from state to non-state actors. Current global economic power has a multipolar distribution, shared between the United States, European Union, Japan and BRICs, with no balance of power between these poles, opposed by the strong ambition of rising countries, China especially, China that rivals the traditional powers represented by the developed countries. The evolution of the main macroeconomic indicators given by the most important global organizations, shows a gradual transition towards a multipolar world. Therefore, the United States is and will remain for a long period of time the global economic leader. However, as China, India and Brazil are growing rapidly, and Russia is looking for lost status, the world is becoming multipolar.

Nationalist attention has always been devoted, at various occasions, to the Brazilian nuclear sector. However, since Brazilian society has many needs and the Brazilian government always had numerous energy options, this sector has not been developed as it could be.

  6. Global implications of U.S. power deregulation

    Maschoff, D.C.

    1996-01-01

    With U.S. power deregulation remaining a topic that is dominating the entire North American energy marketplace, this paper provides an update of events occurring in U.S. electric power markets, offering some observations about changes due to increasing competition in electric power markets, and discusses some reasons why the events in U.S. electric power markets will soon transform global energy markets. How quickly is the move from local service territory to global markets proceeding? More than fifty U.S. utility companies with revenues of over $1 billion (U.S.) will soon be actively seeking and participating in global business opportunities. Using the same logic that led them to pursue utility initiatives nationally, U.S. utilities will use their core capabilities to compete in global energy services markets. In connection with these global initiatives, U.S. utilities will bring the same fuel-neutral, gas-electric perspective to international electric power and natural gas markets. (Author)

  7. The European Union’s normative power in global politics

    comparison. Both political and scholarly assessments argue that ‘we are one of the most important, if not the most important, normative powers in the world’ (Barroso in Peterson, 2008: 69) and that ‘Europe has tremendous normative power’ (Moravcsik, 2010: 18). The normative power approach set out here makes...... it possible to explain, understand, and judge the EU in global politics by rethinking the nature of power and actorness in a globalising, multilateralising and multipolarising era. The EU uses normative power in global politics but the question is whether it is more prone than other actors to do so? In areas...... which are core to the ‘European project’, it seems clear that the EU is more disposed to use normative power....

  8. Global wind power potential: Physical and technological limits

    Castro, Carlos de; Mediavilla, Margarita; Miguel, Luis Javier; Frechoso, Fernando

    2011-01-01

    This paper is focused on a new methodology for the global assessment of wind power potential. Most of the previous works on the global assessment of the technological potential of wind power have used bottom-up methodologies (e.g. ). Economic, ecological and other assessments have been developed, based on these technological capacities. However, this paper tries to show that the reported regional and global technological potential are flawed because they do not conserve the energetic balance on Earth, violating the first principle of energy conservation (). We propose a top-down approach, such as that in , to evaluate the physical-geographical potential and, for the first time, to evaluate the global technological wind power potential, while acknowledging energy conservation. The results give roughly 1 TW for the top limit of the future electrical potential of wind energy. This value is much lower than previous estimates and even lower than economic and realizable potentials published for the mid-century (e.g. ). - Highlights: → Reported wind power potentials are flawed because they violate energy conservation. → For the first time, it is evaluated the technological wind power potential with a top-down approach. → Our results show 1 TWe for the limit of wind power energy, which is much lower than previous estimates.

  9. Power shift -- Cool solutions to global warming

    2000-11-01

    The argument advanced in this paper by the Suzuki Foundation is that Canada, a rich, industrialized nation that has often led the world in technological advances, including advances in the energy sector, is lagging behind Europe and Japan in utilizing new energy-efficient technologies and techniques, despite the fact that these new approaches could reduce energy costs, improve air quality and public health stimulate new industries and create jobs. The paper describes an analytical model created by Ralph Torrie, one of Canada's foremost sustainable energy experts, which shows that based on population and economic growth, Canada's emissions will continue to grow to 30 percent above today's levels by 2010, instead of being reduced to 94 per cent of 1990 levels as required by the Kyoto Protocol. The end-use model created by Torrie runs various scenarios regarding the level and mix of activity, technological efficiency and fuel shares showing their effect of GHG emissions levels. Beginning with 1995 as the base-year, and assuming population growth of 19 per cent and a growth in transportation of 38 per cent over the next 30 years, GHG emission reduction scenarios are produced for people and freight transportation, residential and commercial buildings, industrial energy use, power production and non-energy sources. The GHG savings described in the model show that a 50 per cent reduction by 2030 is conceivable even with technologies that are already available. To get there, however, will require wholehearted effort by both the public and private sectors. Regulation, public investment, innovative market mechanisms and behavioral changes will all have significant roles to play if GHG emission levels of this magnitude are to be achieved

    The paper examines the extent to which nuclear power could help ameliorate the greenhouse problem. Topics discussed include: (1) How serious is the environmental threat posed by the greenhouse effect? (2) How large a part do fossil fuels play in producing greenhouse gases? (3) Is it possible to prevent or abate the anticipated global warming? (4) Can nuclear power play a significant role? (5) What overall approached might best reduce greenhouse emissions? Global cooperativeness in addressing the problem will be essential. 14 refs., 5 tabs

  12. Global analysis of a renewable micro hydro power generation plant

    Rahman, Md. Shad; Nabil, Imtiaz Muhammed; Alam, M. Mahbubul

    2017-12-01

    Hydroelectric power or Hydropower means the power generated by the help of flowing water with force. It is one the best source of renewable energy in the world. Water evaporates from the earth's surface, forms clouds, precipitates back to earth, and flows toward the ocean. Hydropower is considered a renewable energy resource because it uses the earth's water cycle to generate electricity. As far as Global is concerned, only a small fraction of electricity is generated by hydro-power. The aim of our analysis is to demonstrate and observe the hydropower of the Globe in micro-scale by our experimental setup which is completely new in concept. This paper consists of all the Global and National Scenario of Hydropower. And how we can more emphasize the generation of Hydroelectric power worldwide.

  13. Global Status of Nuclear Power: Prospects and Challenges

    Tayobeka, B. M.

    2010-01-01

    Global energy requirements and the share of electricity in total energy consumption are increasing rapidly, and the contribution of nuclear power is projected to increase significantly. Out of the 29 countries currently using nuclear power for electricity generation, 22 intend to allow new plants to be built, and, of those, the majority are actively supporting the increased use of nuclear power, some by providing incentives. Most of these countries are expected to build reactors with a generating capacity of over 1000 MW(e). Only three countries continue to have a policy to phase out the use of nuclear energy in the future by not replacing existing operating nuclear power plants and with no consideration of the option of new nuclear plants.In addition, a growing number of countries are expressing interest in introducing nuclear power. Of the more than 60 countries that have expressed such an interest in recent years, over 20 are actively considering nuclear power programmes to meet their energy needs and the others have expressed interest in understanding the issues associated with the introduction of nuclear power.The drivers for rising expectations for nuclear power include: growing energy demand, concern over national energy supply security, the increasingly volatile price of fossil fuels and global environmental concerns. The drivers appear to be the same for countries expanding existing nuclear programmes and those seeking to introduce programmes. The projections made by different international organizations indicate a significant growth in the use of nuclear power. The IAEA projections indicate a world total for nuclear electrical generating capacity of between 445 and 543 GW(e) by 2020 and between 511 and 807 GW(e) by 2030. This paper takes a detailed look into the global status of nuclear power, highlighting challenges and prospects of the technology going into the next century.(author).

  16. The status and prospects of the debate upon the global warming and nuclear power

    Yim, C. Y.

    2001-01-01

    Possible climate change caused by global warming becomes one of the most serious challenges that mankind shall tackle in 21 st century. Nuclear power, which doesn't emit any greenhouse gas during the generation of electricity, is a promising solution to mitigate the global warming. However, there are still debates about the role of nuclear power related to the subjects such as safety, radioactive waste management and nuclear proliferation risk in the international climate change talks. This paper introduces on-going negotiation focused on the nuclear power and then, gives some prospects on the future negotiations. Finally the brief analysis of their impacts on domestic nuclear industry is carried out

  17. Canada's global health role: supporting equity and global citizenship as a middle power.

    Nixon, Stephanie A; Lee, Kelley; Bhutta, Zulfiqar A; Blanchard, James; Haddad, Slim; Hoffman, Steven J; Tugwell, Peter

    2018-02-22

    Canada's history of nation building, combined with its status as a so-called middle power in international affairs, has been translated into an approach to global health that is focused on equity and global citizenship. Canada has often aspired to be a socially progressive force abroad, using alliance building and collective action to exert influence beyond that expected from a country with moderate financial and military resources. Conversely, when Canada has primarily used economic self-interest to define its global role, the country's perceived leadership in global health has diminished. Current Prime Minister Justin Trudeau's Liberal federal government has signalled a return to progressive values, driven by appreciation for diversity, equality, and Canada's responsibility to be a good global citizen. However, poor coordination of efforts, limited funding, and the unaddressed legacy of Canada's colonisation of Indigenous peoples weaken the potential for Canadians to make meaningful contributions to improvement of global health equity. Amid increased nationalism and uncertainty towards multilateral commitments by some major powers in the world, the Canadian federal government has a clear opportunity to convert its commitments to equity and global citizenship into stronger leadership on the global stage. Such leadership will require the translation of aspirational messages about health equity and inclusion into concrete action at home and internationally. Copyright © 2018 Elsevier Ltd.

    Although nuclear power presents problems of waste, safety and non-proliferation, many people understand that it is an essential energy for addressing the global climate and reducing CO2. However, a vague negative-image to the radiation and nuclear power is deep-rooted among the public. Young generation is not an exception. It is very important to transfer many information from the experienced generation in the industry to young generations. In this paper, the research that applied the information intelligence to nuclear power, which involves of the nuclear fuel cycle, and the communication related activities for the social acceptance and improvement.

    We survey some known facts and open questions concerning the global properties of 3+1 dimensional space--times containing a compact Cauchy surface. We consider space--times with an $\\ell$--dimensional Lie algebra of space--like Killing fields. For each $\\ell \\leq 3$, we give some basic results and conjectures on global existence and cosmic censorship. For the case of the 3+1 dimensional Einstein equations without symmetries, a new small data global existence result is announced.

  20. Assessing the environmental impacts of freshwater thermal pollution from global power generation in LCA.

    Raptis, Catherine E; Boucher, Justin M; Pfister, Stephan

    2017-02-15

    Freshwater heat emissions from power plants with once-through cooling systems constitute one of many environmental pressures related to the thermoelectric power industry. The objective of this work was to obtain high resolution, operational characterization factors (CF) for the impact of heat emissions on ecosystem quality, and carry out a comprehensive, spatially, temporally and technologically differentiated damage-based environmental assessment of global freshwater thermal pollution. The aggregation of CFs on a watershed level results in 12.5% lower annual impacts globally and even smaller differences for the most crucial watersheds and months, so watershed level CFs are recommended when the exact emission site within the basin is unknown. Long-range impacts account for almost 90% of the total global impacts. The Great Lakes, several Mississippi subbasins, the Danube, and the Yangtze are among the most thermally impacted watersheds globally, receiving heat emissions from predominantly coal-fuelled and nuclear power plants. Globally, over 80% of the global annual impacts come from power plants constructed during or before the 1980s. While the impact-weighted mean age of the power plants in the Mississippi ranges from 38 to 51years, in Chinese watersheds including the Yangtze, the equivalent range is only 15 to 22years, reflecting a stark contrast in thermal pollution mitigation approaches. With relatively high shares of total capacity from power plants with once-through freshwater cooling, and tracing a large part of the Danube, 1kWh of net electricity mix is the most impactful in Hungary, Bulgaria and Serbia. Monthly CFs are provided on a grid cell level and on a watershed level for use in Life Cycle Assessment. The impacts per generating unit are also provided, as part of our effort to make available a global dataset of thermoelectric power plant emissions and impacts. Copyright © 2016 Elsevier B.V.

  1. Politics, Power, Poverty and Global Health: Systems and Frames.

    2016-08-06

    Striking disparities in access to healthcare and in health outcomes are major characteristics of health across the globe. This inequitable state of global health and how it could be improved has become a highly popularized field of academic study. In a series of articles in this journal the roles of power and politics in global health have been addressed in considerable detail. Three points are added here to this debate. The first is consideration of how the use of definitions and common terms, for example 'poverty eradication,' can mask full exposure of the extent of rectification required, with consequent failure to understand what poverty eradication should mean, how this could be achieved and that a new definition is called for. Secondly, a criticism is offered of how the term 'global health' is used in a restricted manner to describe activities that focus on an anthropocentric and biomedical conception of health across the world. It is proposed that the discourse on 'global health' should be extended beyond conventional boundaries towards an ecocentric conception of global/planetary health in an increasingly interdependent planet characterised by a multitude of interlinked crises. Finally, it is noted that the paucity of workable strategies towards achieving greater equity in sustainable global health is not so much due to lack of understanding of, or insight into, the invisible dimensions of power, but is rather the outcome of seeking solutions from within belief systems and cognitive biases that cannot offer solutions. Hence the need for a new framing perspective for global health that could reshape our thinking and actions. © 2016 by Kerman University of Medical Sciences.

  4. Global status of nuclear power and the needed human resources

    Bernido, Corazon C.

    2009-01-01

    According to projections of the OECD/IEA, the world energy demand will expand by 45% from now until 2030, with coal accounting for more than a third of the overall rise. To reduce greenhouse gases and mitigate climate change, many countries are resorting to renewables and nuclear power. Some statistics about nuclear energy in the global energy mix and about nuclear power plants worldwide, as well as the energy situation in the country are presented. According to sources from the Department of Energy on the Philippine Energy Plan, nuclear power is a long-term energy option and will likely enter the energy mix by 2025. Preparation of the infrastructure for nuclear power has to start ten to fifteen years before the first plant comes online. The needed human resources, the education and training required are present.

  5. On nuclear power, population and sustainable global civilization

    Ishiguro, Yuji

    2007-01-01

    Humanity is facing a multitude of difficult problems that threaten not only human development but the very continuity of civilization. The fundamental cause is the size of the human population but at present the subject is not discussed in international fora. It is not clear if it is wishfully avoided or if it is not recognized as the fundamental problem. Without limiting fertility and population globally, there will be no future for civilization as we know it and there will be no need for nuclear power as a source of energy. Instead, nuclear power will be the principal agent of the end. The nuclear community is in a position to point out the problem and propose a solution. Principles of sustainability and a path to a sustainable global civilization are shown. (author)

  6. Relative Power in Sibling Relationships Across Adolescence.

    Lindell, Anna K; Campione-Barr, Nicole

    2017-06-01

    During childhood, older siblings typically hold a more powerful position in their relationship with their younger siblings, but these relationships are thought to become more egalitarian during adolescence as siblings begin to prepare for their relationships as adults and as younger siblings become more socially and cognitively competent. Little is known about relationship factors that may explain this shift in power dynamics, however. The present study therefore examined longitudinal changes in adolescents' and their siblings' perceptions of sibling relative power from age 12 to 18 (n = 145 dyads), and examined whether different levels of sibling relationship positivity and negativity, as well as sibling structural variables, indicated different over-time changes in relative power. Multilevel models indicated that adolescents reported significant declines in their siblings' relative power across adolescence, with older siblings relinquishing the most power over time. However, only siblings with less positively involved relationships reported declines in relative power, suggesting that siblings who maintain highly involved relationships may not become more egalitarian during adolescence. © 2017 Wiley Periodicals, Inc.

  7. On global environment problems in electric power business

    Sugi, Masashi

    1992-01-01

    The former environmental problems were atmospheric pollution, water quality contamination, noise and vibration nuisance, waste disposal and so on mainly at interior or district level, but now, the influence that the problems such as the global warming due to carbon dioxide emission, the ozone layer breaking due to freon gas, acid rain going over boundaries and so on exert to environment spreads to wide areas, therefore, various research and investigation have been carried out as the environmental problems on global scale at national and international levels. It has become an important subject to make the preservation of global environment and durable economical development compatible by effectively utilizing limited resources and energy. The electric power companies have advanced positively the prevention of pollution and the preservation of environment, and attained the environment preservation of top level in the world. The consciousness of people on environmental problems has heightened, therefore the construction and operation of power plants harmonized to districts are important. The countermeasures to environmental problems taken by electric power companies are reported. (K.I.)

    Das, S.K. [Indian School of Mines, Dhanbad (India). Centre of Longwall Mine Mechanisation

    1996-04-01

    The efficiency of hydraulic powered roof support systems mainly depends upon the efficient control and operation of hydraulic valves and their associated accessories. From 1961 to 1994 tremendous efforts had been made for the development of higher and higher efficient, reliable but simpler control systems starting from the manual hydraulic to electro-hydraulic and finally computer based electronic control system. A global survey of development of various types and design of control systems of powered roof supports has been made and many of them are highlighted in the paper for making this work a small emblem regarding the efforts of development of the controls of powered roof support systems by the global engineers of the 20th century. Many of the control systems are no longer in use and have totally vanished from this earth and many more control systems including their literatures may vanish from this world in the coming decades. This work may give a guideline regarding the selection of right type of control systems for the powered supports in future. 14 refs., 6 figs.

  10. Global radioxenon emission inventory based on nuclear power reactor reports.

    Kalinowski, Martin B; Tuma, Matthias P

    2009-01-01

    Atmospheric radioactivity is monitored for the verification of the Comprehensive Nuclear-Test-Ban Treaty, with xenon isotopes 131mXe, 133Xe, 133mXe and 135Xe serving as important indicators of nuclear explosions. The treaty-relevant interpretation of atmospheric concentrations of radioxenon is enhanced by quantifying radioxenon emissions released from civilian facilities. This paper presents the first global radioxenon emission inventory for nuclear power plants, based on North American and European emission reports for the years 1995-2005. Estimations were made for all power plant sites for which emission data were unavailable. According to this inventory, a total of 1.3PBq of radioxenon isotopes are released by nuclear power plants as continuous or pulsed emissions in a generic year.

    Nuclear power is currently making an important contribution to our energy requirements. It provides 17% of the world's electricity today --- almost 20% in the US. Reducing the emissions of carbon dioxide over the next 30 to 50 years sufficiently to address the issue of global warming can only be accomplished by a combination of much improved energy efficiency, substantial growth in use of nuclear power, and substantial growth in use of renewable energy. This paper discusses new initiatives in the major nuclear technologies (LWR, HTGR, LMR) which are emerging from a fundamental reexamination of nuclear power in response to the challenges and opportunities in the 21st century. To fulfill its role, nuclear power must gain worldwide acceptance as a viable energy option. The use of modern technology and ''passive'' safety features in next-generation nuclear power plants offers the potential to simplify their design and operation, enhance their safety, and reduce the cost of electricity. With such improvements, we believe nuclear power can regain public confidence and make a significant contribution to our energy future. 24 refs., 2 figs., 1 tab

  12. Global freshwater thermal emissions from steam-electric power plants with once-through cooling systems

    Raptis, Catherine E.; Pfister, Stephan

    2016-01-01

    Large quantities of heat are rejected into freshwater bodies from power plants employing once-through cooling systems, often leading to temperature increases that disturb aquatic ecosystems. The objective of this work was to produce a high resolution global picture of power-related freshwater thermal emissions and to analyse the technological, geographical and chronological patterns behind them. The Rankine cycle was systematically solved for ∼2400 generating units with once-through cooling systems, distinguishing between simple and cogenerative cycles, giving the rejected heat as a direct output. With large unit sizes, low efficiencies, and high capacity factors, nuclear power plants reject 3.7 GW heat into freshwater on average, contrasting with 480 MW rejected from coal and gas power plants. Together, nuclear and coal-fuelled power plants from the 1970s and 1980s account for almost 50% of the rejected heat worldwide, offering motivation for their phasing out in the future. Globally, 56% of the emissions are rejected into rivers, pointing to potential areas of high thermal pollution, with the rest entering lakes and reservoirs. The outcome of this work can be used to further investigate the identified thermal emission hotspots, and to calculate regionalized water temperature increase and related impacts in environmental, energy-water nexus studies and beyond. - Highlights: • The thermodynamic cycles of ∼2400 power units with once-through cooling were solved. • Global freshwater heat emissions depend on technology, geography & chronology. • Half the global emissions come from nuclear and coal plants from the 70s & 80s. • Hotspots of freshwater thermal emissions were identified globally. • Global georeferenced emissions are available for use in water temperature models.

  13. Global Sustainable Development: The Role of Nuclear Power

    Hatcher, Stanley R.

    1990-01-01

    The inevitable growth in the world's population and the need for a reasonable standard of living for all nations will drive the demand for energy to much higher levels than the world has yet experienced. A radical improvement in energy efficiency and conservation could limit the global annual demand to 100 GJ per person. consumption of North America. With the developing nations achieving a standard of living commensurate with this level, the global energy demand would increase by a factor of 2.5 to 1000 EJ per year. Concern over the impact of CO 2 emissions on global warming will likely lead to an international consensus on some reduction in the use of fossil fuels. To maintain environmental sustainability, all nations of the world would need to limit their fossil fuel consumption, particularly those in North America and Europe. Other energy sources will play an important role in all regions. However, the main burden is likely to fall upon nuclear energy as an essential element of the total energy supply. The danger eliminated while sustaining global development if the governments of the world commit to the use of nuclear power on a global scale. The industrial intrastucture can be put in place for such a major international program. A more difficult question is the availability of the necessary financing. On a global scale the financial requirement is within the range of current military expenditures. However, it is clear that not all the countries of Asia, Africa and Latin America will be able to finance their own needs. A new international cooperative program will be necessary. The needed change in energy patterns is dramatic and will take time to implement. The change should be underway by the beginning of the next century. Otherwise the world faces the prospect of environmental disaster and social disruption as the nations struggle to improve their living standards through the increased use of fossil fuels. The role of nuclear power in providing the energy for

  15. Mapping the impacts of thermoelectric power generation: a global, spatially explicit database

    Raptis, Catherine; Pfister, Stephan

    2017-04-01

    Thermoelectric power generation is associated with environmental pressures resulting from emissions to air and water, as well as water consumption. The need to achieve global coverage in related studies has become pressing in view of climate change. At the same time, the ability to quantify impacts from power production on a high resolution remains pertinent, given their highly regionalized nature, particularly when it comes to water-related impacts. Efforts towards global coverage have increased in recent years, but most work on the impacts of global electricity production presents a coarse geographical differentiation. Over the past few years we have begun a concerted effort to create and make available a global georeferenced inventory of thermoelectric power plant operational characteristics and emissions, by modelling the relevant processes on the highest possible level: that of a generating unit. Our work extends and enhances a commercially available global power plant database, and so far includes: - Georeferencing the generating units and populating the gaps in their steam properties. - Identifying the cooling system for 92% of the global installed thermoelectric power capacity. - Using the completed steam property data, along with local environmental temperature data, to systematically solve the Rankine cycle for each generating unit, involving: i) distinguishing between simple, reheat, and cogenerative cycles, and accounting for particularities in nuclear power cycles; ii) accounting for the effect of different cooling systems (once-through, recirculating (wet tower), dry cooling) on the thermodynamic cycle. One of the direct outcomes of solving the Rankine cycle is the cycle efficiency, an indispensable parameter in any study related to power production, including the quantification of air emissions and water consumption. Another direct output, for those units employing once-through cooling, is the rate of heat rejection to water, which can lead to

  16. Hydroelectric power and global environmental problems: benefits and environmental impacts

    Chabot, B.

    1992-01-01

    The risk of global warming is one of the most serious global environmental problems. It is due to the increase of greenhouse gases emissions, mainly because of the use of fossil fuels in the energy sector, particularly for electricity generation. At an international level, experts now agree that measures are to be taken to reduce this risk. In the energy sector, an improvement of energy efficiency and an increase of nuclear electricity generation are often presented as the best available solutions. Renewable energy sources are often presented as a solution with a negligible potential impact, and sometimes, hydro power is even forgotten, or its coasts and its potential impacts on local environment are presented as an obstacle to its positive contribution to the reduction of global warming risk. Without denying the positive impacts of other solutions, this paper explains the possibilities and the benefits of an increased use of hydroelectric power, when implemented with a minimum impact on local environment and with a synergistic effect with the rational use of generated energy, in order to have access to a sustainable development. 19 refs., 6 figs

    1998-05-15

    This paper takes a view of hydraulic and pneumatic industry. The United States accounts for 33% of hydraulic and pneumatic device shipment, while Japan accounts for 16% and Germany 14%. Japan has recorded the highest shipment record in 1991, but the shipment decreased largely in 1992 as a result of the collapse of the bubble economy. Thereafter, pneumatic devices recovered production in 1995, and continuing smooth growth since then. However, hydraulic devices have not reached the level of 1989. Pneumatic devices have achieved great progress as a result of making them lighter, thinner, shorter and smaller to meet users` strong demands, development of energy saving, space saving and life extending technologies and control technologies, function combination, and diversification. International competition is so intense that, in order to survive this mega-competition age, efforts must be made in areas of noise, oil leakage, positioning control and energy conservation as substantial technological issues. Measures against global environmental problems may include prevention of pollution and disaster caused from working oils and development of hydraulic devices. Transferring the excellent Japanese technologies and know-hows to developing countries constitutes international contribution. Progress in hydraulic and pneumatic technologies combined with electronics technologies is also desired. 3 figs., 1 tab.

  18. Historical construction costs of global nuclear power reactors

    Lovering, Jessica R.; Yip, Arthur; Nordhaus, Ted

    2016-01-01

    The existing literature on the construction costs of nuclear power reactors has focused almost exclusively on trends in construction costs in only two countries, the United States and France, and during two decades, the 1970s and 1980s. These analyses, Koomey and Hultman (2007); Grubler (2010), and Escobar-Rangel and Lévêque (2015), study only 26% of reactors built globally between 1960 and 2010, providing an incomplete picture of the economic evolution of nuclear power construction. This study curates historical reactor-specific overnight construction cost (OCC) data that broaden the scope of study substantially, covering the full cost history for 349 reactors in the US, France, Canada, West Germany, Japan, India, and South Korea, encompassing 58% of all reactors built globally. We find that trends in costs have varied significantly in magnitude and in structure by era, country, and experience. In contrast to the rapid cost escalation that characterized nuclear construction in the United States, we find evidence of much milder cost escalation in many countries, including absolute cost declines in some countries and specific eras. Our new findings suggest that there is no inherent cost escalation trend associated with nuclear technology. - Highlights: •Comprehensive analysis of nuclear power construction cost experience. •Coverage for early and recent reactors in seven countries. •International comparisons and re-evaluation of learning. •Cost trends vary by country and era; some experience cost stability or decline.

    Approximately 80% of the world's electricity supply depends on reliable water resources. Thermoelectric and hydropower plants have been impacted by low flows and floods in recent years, notably in the US, Brazil, France, and China, amongst other countries. The dependence on reliable flows imputes a large vulnerability to the electricity supply system due to hydrological variability and the impacts of climate change. Using an updated dataset of global electricity capacity with global climate and hydrological data from the ISI-MIP project, we present an overview analysis of power sector vulnerability to hydroclimatic risks, including low river flows and peak flows. We show how electricity generation in individual countries and transboundary river basins can be impacted, helping decision-makers identify key at-risk geographical regions. Furthermore, our use of a multi-model ensemble of climate and hydrological models allows us to quantify the uncertainty of projected impacts, such that basin-level risks and uncertainty can be compared.

Après un bref rappel des concepts de base de la tectonique globale et de la structure de la lithosphère, on fait le point des connaissances acquises à ce jour sur les principaux paramètres intervenant lors des déformations intraplaques - les déplacements absolus des plaques qui conditionnent les relations entre phénomènes profonds et déformations de surface ; - les hétérogénéités de la croûte terrestre qui introduisent des déséquilibres mécaniques - dissymétrie de structure des marges stables, - variations d'épaisseur et de composition chimique de la croûte continentale, - modifications des charges lithostatiques par sédimentation ou érosion. - les phénomènes thermiques qui n'apparaissent pas, sauf pour les marges stables, directement en relation avec la tectonique globale mais avec la géométrie de la lithosphère continentale mal connue à ce jour; - les forces motrices ou résistantes responsables du mouvement des plaques c'est en réalité l'étude des déformations actuelles qui doit permettre de tester la validité des mécanismes proposés par la tectonique globale. Ces mécanismes, une fois établis, permettront une meilleure compréhension des déformations passées affectant le sédimentaire dans la mesure où l'on tient compte des hétérogénéités anciennes du substratum. Après cet examen critique, on présente en conclusion un exemple concret, l'évolution structurale des grabens rhénans, évolution qui résulte de l'influence conjuguée des trois facteurs précédemment examinés : phénomènes thermiques, hétérogénéité de la croûte, mouvement des plaques.

    1990-01-01

    The radiation losses and the global power balance for Ohmic and neutral beam heated plasmas have been investigated in different JT-60 configurations. Discharges with a TiC coated molybdenum wall and with a graphite wall, with limiter, outer and lower X-point configurations have been studied by bolometric measurements, thermocouples and an infrared TV camera. In neutral beam heated outer X-point discharges with a TiC coated molybdenum first wall, the radiation loss of the main plasma was very low (10% of the absorbed power). The radiation loss due to oxygen was dominant in this case. On the contrary, in discharges with TiC coated molybdenum limiters the radiation loss was very high (>60% of the absorbed power). In the discharges with a graphite wall the radiated power from the main plasma was 20-25% for both limiter and lower X-point configurations. In lower X-point discharges the main contributor to the radiation loss was oxygen, whereas in limiter discharges the loss due to carbon was equal to the loss due to oxygen. The radiation loss from the lower X-point divertor increased with increasing electron density of the main plasma. (author). 33 refs, 14 figs, 1 tab

  4. Global warming and oil: Can nuclear power make a difference?

    Bodansky, D.

    1991-01-01

    A responsible energy policy, for the United States and the world, must address two needs: to restrain the rate of fossil fuel consumption, and to reduce the consumption of oil. Unless the first is accomplished, the world may experience major climate changes, some perhaps disastrous, from the buildup of carbon dioxide and other greenhouse gases. Unless the second is met, we face recurring threats of economic disruption and war, due to the dangerous concentration of the world's oil resources in the Persian Gulf region. Nuclear power has long been cited as a possible answer to these needs. Mr. Bodansky takes a fresh look at the contribution nuclear power could make, in the light of our increased awareness of global warming dangers and the renewed reminders of the instabilities of oil markets. He notes, however, that the basic objections to nuclear power remain. They are well-known, stemming from concerns about reactor safety, waste disposal, nuclear proliferation, and cost. These are old but continuing controversies, involving a tangle of technical, political, social, and economic issues. If nuclear power is to be revived, these concerns clearly must be addressed. 1 fig., 7 tabs

    1994-01-01

    supply, in the world and by region. In the long term, up to 2100, the broad range of uncertainties with regard to population, economic growth and technology evolution prevent from any sound forecast in the field of energy and in particular of nuclear power. The scenario presented in the paper has been prepared for the Inter Governmental Panel on Climate Change (IPCC) in order to illustrate the potential role of nuclear power in alleviating greenhouse gas emissions. The global energy demand projections established by IPCC, which serve as a basis for the nuclear power scenario, assume high economic growth, drastic energy efficiency improvement and the implementation of voluntary policies for greenhouse gas reduction. Under these assumptions, it is estimated that the total primary energy consumption in the world will reach some 660 EJ per annum in 2100 as compared to 330 EJ per annum in 1985. Since the world population is expected to more than double during this time frame, it means that the average energy consumption per capita will a sustained deployment of nuclear power worldwide as a means to reduce greenhouse gas emissions from the energy sector. Although this scenario would require strong commitment to the development of nuclear energy, technical and industrial capabilities would enable its implementation. In view of the potential role of nuclear power in sustainable energy supply strategies, there is a need for continued research and development aiming towards the design and implementation of advanced reactors with enhanced safety, technical and economic performance. Natural nuclear fuel resources could support a broad deployment of nuclear energy production as a major part of the mix of options for sustainable supply in the long term. The challenge for the nuclear industry is to restore the confidence in nuclear energy and enhance its social acceptability through the design and implementation of sound technical solutions for nuclear power plants, fuel cycle

  9. Power Watch - A global, open database of power plants that supports research on climate, water and air pollution impact of the global power sector.

    Friedrich, J.; Kressig, A.; Van Groenou, S.; McCormick, C.

    2017-12-01

    Challenge The lack of transparent, accessible, and centralized power sector data inhibits the ability to research the impact of the global power sector. information gaps for citizens, analysts, and decision makers worldwide create barriers to sustainable development efforts. The need for transparent, accessible, and centralized information is especially important to enhance the commitments outlined in the recently adopted Paris Agreement and Sustainable Development Goals. Offer Power Watch will address this challenge by creating a comprehensive, open-source platform on the world's power systems. The platform hosts data on 85% of global installed electrical capacity and for each power plant will include data points on installed capacity, fuel type, annual generation, commissioning year, with more characteristics like emissions, particulate matter, annual water demand and more added over time. Most of the data is reported from national level sources, but annual generation and other operational characteristiscs are estimated via Machine Learning modeling and remotely sensed data when not officially reported. In addition, Power Watch plans to provide a suite of tools that address specific decision maker needs, such as water risk assessments and air pollution modeling. Impact Through open data, the platform and its tools will allow reserachers to do more analysis of power sector impacts and perform energy modeling. It will help catalyze accountability for policy makers, businesses, and investors and will inform and drive the transition to a clean energy future while reaching development targets.

  10. Global impact of carbon-14 from nuclear power reactors

    Moghissi, A.A.; Carter, M.W.

    1977-01-01

    Carbon-14 is produced by nuclear power reactors, predominently as a result of the interaction of a neutron and nitrogen-14 both in the fuel and in the coolant. Several other reactions also contribute to the production of carbon-14. Present operational procedures, in general, for reactors and fuel reprocessing plants result in the release of carbon-14 into the environment. Combustion of fossil fuels and certain industrial operations contribute to the supply of CO 2 in the atmosphere and this contribution is essentially free of carbon-14. Future carbon-14 burdens by assuming a thorough mixing of all CO 2 in the atmosphere is predicted. Available data on electric power generation, fossil fuel combustion and certain other information are used to calculate the projected specific activity of carbon-14 by the year 2000 and the twenty-first century. According to these calculations, the global population dose from carbon-14 can be substantial. Also, carbon-14 in the vicinity of nuclear power reactors is considered. Because of the chemistry of carbon-14, it is shown that local problems may be more significant around BWR's as compared to PWR's. Based on environmental considerations of carbon-14, its increasing production and discharge into the atmosphere, and available control technology, it is recommended that nitrogen use and its presence be minimized in pertinent reactor components and operations

  16. Is nuclear power part of Australia's global warming solutions?

    Lowe, I.

    2007-01-01

    Forty years ago, I was preparing for my final exams. Having studied electrical engineering and science part-time for seven years at the University of New South Wales, I did well enough to spend the following year doing honours in physics. I then went to the United Kingdom for doctoral studies at the University of York, supported by the UK Atomic Energy Authority. At the time, like most young physicists, I saw nuclear power as the clean energy source of the future. Here, I want to tell you why my professional experience has led me to reject that view. There is no serious doubt that climate change is real, it is happening now and its effects are accelerating. It is already causing serious economic impacts: reduced agricultural production, increased costs of severe events like fires and storms, and the need to consider radical, energy-intensive and costly water supply measures such as desalination plants. The alarming consequences of climate change have driven distinguished scientists like James Lovelock to conclude that the situation is desperate enough to reconsider our attitude to nuclear power. I agree with Lovelock about the urgency of the situation, but not about the response. The science is very clear. We need to reduce global greenhouse pollution by about 60%, ideally by 2050. To achieve that global target, allowing for the legitimate material expectations of poorer countries, Australia's quota will need to be at least as strong as the UK's goal of 60% by 2050 and preferably stronger. Our eventual goal will probably be to reduce our greenhouse pollution by 80-90%. How can we reach this ambitious target?

  17. Developmental changes of BOLD signal correlations with global human EEG power and synchronization during working memory.

    Lars Michels

    Full Text Available In humans, theta band (5-7 Hz power typically increases when performing cognitively demanding working memory (WM tasks, and simultaneous EEG-fMRI recordings have revealed an inverse relationship between theta power and the BOLD (blood oxygen level dependent signal in the default mode network during WM. However, synchronization also plays a fundamental role in cognitive processing, and the level of theta and higher frequency band synchronization is modulated during WM. Yet, little is known about the link between BOLD, EEG power, and EEG synchronization during WM, and how these measures develop with human brain maturation or relate to behavioral changes. We examined EEG-BOLD signal correlations from 18 young adults and 15 school-aged children for age-dependent effects during a load-modulated Sternberg WM task. Frontal load (in-dependent EEG theta power was significantly enhanced in children compared to adults, while adults showed stronger fMRI load effects. Children demonstrated a stronger negative correlation between global theta power and the BOLD signal in the default mode network relative to adults. Therefore, we conclude that theta power mediates the suppression of a task-irrelevant network. We further conclude that children suppress this network even more than adults, probably from an increased level of task-preparedness to compensate for not fully mature cognitive functions, reflected in lower response accuracy and increased reaction time. In contrast to power, correlations between instantaneous theta global field synchronization and the BOLD signal were exclusively positive in both age groups but only significant in adults in the frontal-parietal and posterior cingulate cortices. Furthermore, theta synchronization was weaker in children and was--in contrast to EEG power--positively correlated with response accuracy in both age groups. In summary we conclude that theta EEG-BOLD signal correlations differ between spectral power and

    This issue of MEDICC Review appears in the wake of a media splash on the reopening of the Cuban and US embassies in Washington and Havana, signaling the renewal of full diplomatic relations between the two governments. Although the US embargo is still law and one of the thorniest bilateral issues remaining, the Obama administration's bold opening towards Cuba is being echoed in the chambers of Senate committees, calling for an end to the policy in place since 1962. Meanwhile, people from the United States have begun to travel to Cuba in droves, and for the first time in many years, we perceive real hope that cooperation may replace hostility-at least in the sectors that most matter to ordinary people in both nations.

    Full Text Available This paper addresses the  generation  of  rents  and  the  distribution  of  gains  in  the  global  operations  of  governed Global  Value  Chains  (GVCs  and  seeks  to  provide  an  architecture  for  analyzing  the  governance  of  GVCs.  It distinguishes between four sets of rent—gifts of nature; innovation rents; exogenously defined rents; and market power—and three spheres of governance—setting the rules -“legislative governance”; implementing the rules -“executive governance”; and monitoring rules and sanctioning malfeasance -“judicial governance.” The exercise of governance power in GVCs over the generation, protection and appropriation of rents is considered though the lens of four sets of key GVC stakeholders—the corporate sector, civil society organizations, the nation state and supranational institutions. This general analysis is given flesh through three case studies: food-safety standards in GVCs; taxation  policies  and  competition  policies.  In these  sectors,  the  corporate  sector  is  generally  much  more effective in governing rent generation and appropriation in the global operations of GVCs than are the three sets of  non-corporate  stakeholders.  From this  observation  we  offer  a  hypothesis  that  the  capacity  of  non-corporate stakeholders, including national states, to govern GVCs is contingent upon the extent to which this coincides with the interest of the corporate sector. However, as noted, this balance of power between private and non-corporate actors is a contested terrain and dynamic in nature.

  20. Age-related decline in global form suppression

Selective attention, i.e., the ability to focus on relevant and ignore irrelevant information, declines with increasing age; however, how this deficit affects selection of global vs. local configurations remains unknown. On this background, the present study examined for age-related differences in a global...... differences in the subsequent (250–500 ms) posterior contralateral negativity (PCN) indicated that attentional resources were allocated faster to Kanisza, as compared to non-Kanisza, targets in both age groups, while the allocation of spatial attention seemed to be generally delayed in older relative...... to younger age. Our results suggest that the enhanced global-local asymmetry in the older age group originated from less effective suppression of global distracter forms on early processing stages – indicative of older observers having difficulties with disengaging from a global default selection mode...

  1. Global Public Goods and The Role of Emerging Power: Considering the Concept of Impure Public Goods

    Liu Rieshøj Yi

    2016-12-01

    Full Text Available The existing analysis of global public goods over-emphasizes the significance of public. Great power as a main provider has played an active role in these strategic initiatives, which may be ignored. In fact, main power has thought about the possible free-riders when providing public goods and making its foreign strategic plan. China’s announcement to “welcome the neighbouring countries to be a free-rider and benefit from China’s rise” is a good example. It is necessary to think about the theory of public goods and take another look at the free-riding phenomenon. The concept of impure public goods may be useful and effective when we understand the reason why global public goods are being provided and are relatively efficient. As an emerging power, China should have a clear strategy on global public goods with a possible “marketing” viewpoint, including more initiatives and specific measures, so that the global public goods provision may be more diverse and well-planned.

  2. A Global Civilian Power? The Future Role of the European Union in International Politics

    Bedrudin Brljavac

    2011-06-01

    Full Text Available Questions about the future of the European Union as an international actor continue to puzzle students of international relations and particularly students of EU foreign policy. What kind of predictions can we make about the future role of the EU in international politics? While the question is often framed in terms of military versus normative and/or global civilian power Europe, there are indications that ambitions in both directions may very well coincide. However, despite the EU’s development towards deepened defense integration since the 1990s, such developments are by far outweighed by developments pointing in the direction of the EU consolidating its role as a global civilian power. In this article, we analyze the union’s civilian policies and contrast the findings of our analysis with developments in the field of Common Security and Defence Policy (CSDP. Based on our analysis of EU enlargement policy, external aid, global environmental policy and the union’s commitment to multilateralism, our conclusion is that the EU’s international role in the next decades will continue to be best described in terms of a global civilian power.

  3. Globfit: Consistently fitting primitives by discovering global relations

    2011-01-01

    Given a noisy and incomplete point set, we introduce a method that simultaneously recovers a set of locally fitted primitives along with their global mutual relations. We operate under the assumption that the data corresponds to a man-made engineering object consisting of basic primitives, possibly repeated and globally aligned under common relations. We introduce an algorithm to directly couple the local and global aspects of the problem. The local fit of the model is determined by how well the inferred model agrees to the observed data, while the global relations are iteratively learned and enforced through a constrained optimization. Starting with a set of initial RANSAC based locally fitted primitives, relations across the primitives such as orientation, placement, and equality are progressively learned and conformed to. In each stage, a set of feasible relations are extracted among the candidate relations, and then aligned to, while best fitting to the input data. The global coupling corrects the primitives obtained in the local RANSAC stage, and brings them to precise global alignment. We test the robustness of our algorithm on a range of synthesized and scanned data, with varying amounts of noise, outliers, and non-uniform sampling, and validate the results against ground truth, where available. © 2011 ACM.

  5. The development of global energy supply as a succession of energy-related innovation processes. A qualitative model approach to assess the use of nuclear power; Die Entwicklung globaler Energieversorgung als Abfolge energietechnischer Innovationsprozesse. Ein qualitativer Modellansatz zur historischen Einordnung der Kernenergie

    Herrmann, Dieter

    2017-04-15

    Often, the development of the world energy supply is adopted as a painful sequence of the exhaustible and polluting use of primary energy sources. Therefore the expectations in practically inexhaustible and environmentally neutral renewable energy sources are high. However, in fact, it depends on the available production, conversion, and utilization technology, which sources of energy are suitable to meet given demands and requirements. In particular, the development of the energy demand requires energy technology innovations to use new energy sources, to use known energy sources more efficient and to replace exhaustible energy sources at an early stage by others. The historical development of the global energy supply is a sequence of interrelated energy technology innovation processes. This makes it also possible, to analyse the historical development of nuclear power and to derive a model on the future role of nuclear power worldwide.

  6. Reduced order models inertial manifold and global bifurcations: searching instability boundaries in nuclear power systems

    Suarez Antola, R.

    2009-01-01

    In the framework of an analytic or numerical model of a BWR power plant, this could imply first to find an suitable approximation to the solution manifold of the differential equations describing the stability behaviour of this nonlinear system, and then a classification of the different solution types concerning their relation with the operational safety of the power plant, by distributing the different solution types in relation with the exclusion region of the power-flow map. Then the goal is to obtain the best attainable qualitative and quantitative global picture of plant dynamics. To do this, the construction and the analysis of the so called reduced order models (Rom) seems a necessary step. A reduced order model results after the full system of coupled nonlinear partial differential equations of the plant is reduced to a system of coupled nonlinear ordinary differential equations

  7. Nuclear power a viable alternative in global warming context

    Cretu, Ileana; Balan, Iosif Bogdan; Ionila, Maria; Petra, Nicoleta Mihaela

    2008-01-01

    Energy sources available in the world include: coal, oil, gas, biomass, nuclear, hydroelectric, wind, solar, refuse-based, and hydrogen. In addition, fusion had been originally proposed as the long-term source. Every form of energy generation has both advantages and disadvantages. Burning fuel for energy requirements represent about 88% from the total emission of NO x and CO 2 , and about 90% from SO 2 respectively, and about 72% from suspension powder evacuated into the atmosphere. Global warming represents a real threat and is the most visible sign of the climatic changes which take place all over the world. To reduce the emission of greenhouse gases: carbon dioxide (CO 2 ), methane (CH 4 ), nitrous oxide (N 2 O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulphur hexafluoride (SF 6 ), the 'Kyoto Protocol to the United Nations framework convention on climate change' has been adopted in 1997. According to this protocol European countries must reduce their overall emissions of greenhouse gases by at least 5% below 1990 levels in the commitment period 2008 -- 2012. In this context, because the natural resources for power generation based on the fossil fuels are decreasing and their prices are rising, nuclear power has become a real alternative for classical energy sources. It is indicated by: - Fuel is inexpensive because uranium represents a very small part of nuclear power cost and uranium sediment is found on a large scale all over the world; - No greenhouse emission or acid rain effects occur during a normal operation. Nuclear power is also named 'clean energy'; - Wastes are more compact than those of any source of energy and are stored in underground and secured deposits; - Nuclear energy has a number of advantages which warrant its use as one of the many methods of fulfilling the energy-demand of the world. Even with conservation efforts, energy demand increased and will continue to increase. Using each and every one of these forms of energy

  8. Classification of delocalization power of global unitary operations in terms of LOCC one-piece relocalization

    Akihito Soeda

    2010-06-01

    Full Text Available We study how two pieces of localized quantum information can be delocalized across a composite Hilbert space when a global unitary operation is applied. We classify the delocalization power of global unitary operations on quantum information by investigating the possibility of relocalizing one piece of the quantum information without using any global quantum resource. We show that one-piece relocalization is possible if and only if the global unitary operation is local unitary equivalent of a controlled-unitary operation. The delocalization power turns out to reveal different aspect of the non-local properties of global unitary operations characterized by their entangling power.

  9. Global Health Warning: Definitions Wield Power Comment on "Navigating Between Stealth Advocacy and Unconscious Dogmatism: The Challenge of Researching the Norms, Politics and Power of Global Health".

    Marten, Robert

    2015-12-25

    Gorik Ooms recently made a strong case for considering the centrality of normative premises to analyzing and understanding the underappreciated importance of the nexus of politics, power and process in global health. This critical commentary raises serious questions for the practice and study of global health and global health governance. First and foremost, this commentary underlines the importance of the question of what is global health, and why as well as how does this definition matter? This refocuses discussion on the importance of definitions and how they wield power. It also re-affirms the necessity of a deeper analysis and understanding of power and how it affects and shapes the practice of global health. © 2016 by Kerman University of Medical Sciences.

  10. Dynamics of global supply chain and electric power networks: Models, pricing analysis, and computations

    Matsypura, Dmytro

    In this dissertation, I develop a new theoretical framework for the modeling, pricing analysis, and computation of solutions to electric power supply chains with power generators, suppliers, transmission service providers, and the inclusion of consumer demands. In particular, I advocate the application of finite-dimensional variational inequality theory, projected dynamical systems theory, game theory, network theory, and other tools that have been recently proposed for the modeling and analysis of supply chain networks (cf. Nagurney (2006)) to electric power markets. This dissertation contributes to the extant literature on the modeling, analysis, and solution of supply chain networks, including global supply chains, in general, and electric power supply chains, in particular, in the following ways. It develops a theoretical framework for modeling, pricing analysis, and computation of electric power flows/transactions in electric power systems using the rationale for supply chain analysis. The models developed include both static and dynamic ones. The dissertation also adds a new dimension to the methodology of the theory of projected dynamical systems by proving that, irrespective of the speeds of adjustment, the equilibrium of the system remains the same. Finally, I include alternative fuel suppliers, along with their behavior into the supply chain modeling and analysis framework. This dissertation has strong practical implications. In an era in which technology and globalization, coupled with increasing risk and uncertainty, complicate electricity demand and supply within and between nations, the successful management of electric power systems and pricing become increasingly pressing topics with relevance not only for economic prosperity but also national security. This dissertation addresses such related topics by providing models, pricing tools, and algorithms for decentralized electric power supply chains. This dissertation is based heavily on the following

  11. The Role of Cultural Power and Its Influence on Global Developments

    Gholamreza Mortazavi

    2018-03-01

    Full Text Available The study of the culture power in international politics is very complicated and difficult matter because it has been less explicitly used in the analyses and theorizing of cultural elements, hence the role of culture like political, security and economic factors, is not apparent in the theory of international relations. Many researchers have found that it is not possible to achieve the depth of the relations between nations only by relying on the pure political and economic factors. They prescribe to focus on cultural issues and special attention to the field of culture in order to achieve a realistic cognition of international relations. What doubles the importance of the issue, is the design of some new theories and new intellectual schools, and its effect on global politics. Including, the theory of the clash of civilizations, the dialogue of civilizations, cultural fluidity and postmodernist attitude towards the category of identity and culture, that each of them in some way recommends a particular action framework, according to its noetic framework. Hence, the fundamental question is that: What is the role of culture (soft power in foreign policy and what impact does it have on global changes and developments trend? In response to this, the hypothesis is raised in such a way (trying to produce, procure and persuade values, attitudes, and trends and common attitudes lead to achieve cultural power and, as a result, facilitate the achievement of the national goals and interests of the countries, and promote the foreign policy of the countries and, on the other hand, the use of cultural power, creates a culture of resistance in the field of global politics.

  12. Global map of solar power production efficiency, considering micro climate factors

    Hassanpour Adeh, E.; Higgins, C. W.

    2017-12-01

    Natural resources degradation and greenhouse gas emissions are creating a global crisis. Renewable energy is the most reliable option to mitigate this environmental dilemma. Abundancy of solar energy makes it highly attractive source of electricity. The existing global spatial maps of available solar energy are created with various models which consider the irradiation, latitude, cloud cover, elevation, shading and aerosols, and neglect the influence of local meteorological conditions. In this research, the influences of microclimatological variables on solar energy productivity were investigated with an in-field study at the Rabbit Hills solar arrays near Oregon State University. The local studies were extended to a global level, where global maps of solar power were produced, taking the micro climate variables into account. These variables included: temperature, relative humidity, wind speed, wind direction, solar radiation. The energy balance approach was used to synthesize the data and compute the efficiencies. The results confirmed that the solar power efficiency can be directly affected by the air temperature and wind speed.

  15. The European Union in International Politics: Acting as a Global Civilian Power (GCP

    Bedrudin Brljavac

    2011-01-01

    Full Text Available During the Cold War the European Community lacking common military instruments was perceived as the example of a civilian power. However, in the early 1990s, under the framework of CFSP, the first concrete defence initiatives have been launched. By the end of the 1990s and after the agreement on the Common Security and Defence Policy (CSDP the first Rapid Reaction Forces were on the European military agenda. Such defence and military capabilities challenged the idea of the EU as a civil or civilian power. Thus, a main concern in the paper has been to assess the character and identity of the EU`s activities in the context of international relations. For this purpose, this study has explored the EU policy instruments such as the enlargement policy, external aid, environmental policy at the global level, multilateralism, and the EU armed forces. The study concludes that the enlargement policy accounts for an important EU strategy to shape the international environment through civilian means. Furthermore, the international aid policy of the EU states has primarily been based on the sense of duty to other countries as constructivists point out. The EU has also been vocal and has used environmental foreign policy as an instrument to demonstrate its global leadership role which is a clear indication of its commitment to global welfare. Thanks to its presence in the major multilateral interventions of the last decade, the EU has qualified itself as great supporter of multilateralism. Lastly, the EU military capabilities are not achieved by creating permanent European armed forces but are still based on the voluntary contributions of its member states. Therefore, the EU still can be portrayed as a global civilian power (GCP or civilian power Europe (CPE.

    NASA's POWER project, or the Prediction of the Worldwide Energy Resources project, synthesizes and analyzes data on a global scale. The products of the project find valuable applications in the solar and wind energy sectors of the renewable energy industries. The primary source data for the POWER project are NASA's World Climate Research Project (WCRP)/Global Energy and Water cycle Experiment (GEWEX) Surface Radiation Budget (SRB) project (Release 3.0) and the Global Modeling and Assimilation Office (GMAO) Goddard Earth Observing System (GEOS) assimilation model (V 4.0.3). Users of the POWER products access the data through NASA's Surface meteorology and Solar Energy (SSE, Version 6.0) website (http://power.larc.nasa.gov). Over 200 parameters are available to the users. The spatial resolution is 1 degree by 1 degree now and will be finer later. The data covers from July 1983 to December 2007, a time-span of 24.5 years, and are provided as 3-hourly, daily and monthly means. As of now, there have been over 18 million web hits and over 4 million data file downloads. The POWER products have been systematically validated against ground-based measurements, and in particular, data from the Baseline Surface Radiation Network (BSRN) archive, and also against the National Solar Radiation Data Base (NSRDB). Parameters such as minimum, maximum, daily mean temperature and dew points, relative humidity and surface pressure are validated against the National Climate Data Center (NCDC) data. SSE feeds data directly into Decision Support Systems including RETScreen International clean energy project analysis software that is written in 36 languages and has greater than 260,000 users worldwide.

  18. Knowledge and networks - key sources of power in global health: Comment on "Knowledge, moral claims and the exercise of power in global health".

    Hanefeld, Johanna; Walt, Gill

    2015-02-01

    Shiffman rightly raises questions about who exercises power in global health, suggesting power is a complex concept, and the way it is exercised is often opaque. Power that is not based on financial strength but on knowledge or experience, is difficult to estimate, and yet it may provide the legitimacy to make moral claims on what is, or ought to be, on global health agendas. Twenty years ago power was exercised in a much less complex health environment. The World Health Organization (WHO) was able to exert its authority as world health leader. The landscape today is very different. Financial resources for global health are being competed for by diverse organisations, and power is diffused and somewhat hidden in such a climate, where each organization has to establish and make its own moral claims loudly and publicly. We observe two ways which allow actors to capture moral authority in global health. One, through power based on scientific knowledge and two, through procedures in the policy process, most commonly associated with the notion of broad consultation and participation. We discuss these drawing on one particular framework provided by Bourdieu, who analyses the source of actor power by focusing on different sorts of capital. Different approaches or theories to understanding power will go some way to answering the challenge Shiffman throws to health policy analysts. We need to explore much more fully where power lies in global health, and how it is exercised in order to understand underlying health agendas and claims to legitimacy made by global health actors today.

  19. Outlook for Global Nuclear Power: Energy, Electricity and Nuclear Power Estimates for the Period up to 2050

    Gritsevskyi, A.

    2016-01-01

    Nuclear power's global expansion is projected to continue in the coming decades - albeit at a slowing pace - amid challenges including low fossil fuel prices, a sluggish world economy and the legacy of Japan's Fukushima Daiichi accident. Each year, the IAEA publishes projections of the world's nuclear power generating capacity in Energy, Electricity and Nuclear Power Estimates for the Period up to 2050, now in its 35th edition.The latest projections point to slower growth in nuclear power, in keeping with the trend since the 2011 Fukushima Daiichi accident. The world's nuclear power generating capacity is projected to expand by 2.4 percent by 2030, according to the low projections, compared with 7.7 percent estimated in 2014. In the high case, generating capacity is estimated to grow by 68 percent by 2030, versus 88 percent forecast last year. Uncertainty related to energy policy, license renewals, shutdowns and future constructions accounts for the wide range.The estimates also factor in the likely future retirement of many of the world's 438 nuclear reactors currently in operation, more than half of which are over 30 years old. Despite the need to replace scores of retiring reactors, nuclear power is still set to maintain - and possibly increase - its role in the world's low-carbon energy mix. It's important to understand that these projections, while carefully derived, are not predictions.The estimates should be viewed as very general growth trends, whose validity must be constantly subjected to critical review.(author).

  7. Thermal Aspects Related to Power Assemblies

    PLESCA, A.

    2010-02-01

    Full Text Available In many cases when a power assembly based on power semiconductors is used, catastrophic failure is the result of steep temperature gradient in the localized temperature distribution. Hence, an optimal heatsink design for certain industrial applications has become a real necessity. In this paper, the Pro/ENGINEER software with the thermal simulation integrated tool, Pro/MECHANICA, has been used for thermal study of a specific power semiconductor assembly. A series of steady-state and transient thermal simulations have been performed. The experimental tests have confirmed the simulation results. Therefore, the use of specific 3D modeling and simulation software allows to design special power semiconductor assemblies with a better thermal transfer between its heatsink and power electronic components at given operating conditions.

  8. Global health-related publications in otolaryngology are increasing.

    Chambers, Kyle J; Creighton, Francis; Abdul-Aziz, Dunia; Cheney, Mack; Randolph, Gregory W

    2015-04-01

    Determine trends in global health-related publication in otolaryngology. A review of research databases. A search of publications available on PubMed and nine additional databases was undertaken reviewing two time periods 10 years apart for the timeframes 1998 to 2002 (early time period) and 2008 to 2012 (recent time period) using specific search terms to identify global health-related publications in otolaryngology. Publications were examined for region of origin, subspecialty, type of publication, and evidence of international collaboration. χ and t test analyses were used to identify trends. In the 1998 to 2002 time period, a total of 26 publications met inclusion criteria for the study, with a mean of 5.2 ± 2.8 publications per year. In the 2008 to 2012 time period, a total of 61 publications met inclusion criteria, with a mean of 12.3 ± 5.6 publications per year. The 235% increase in global health-related publications identified between the two study periods was statistically significant (P = .02). The absolute number of publications in which collaboration occurred between countries increased from three in the early time period to nine the recent time period. There has been a significant increase in the volume of global health-related publications in English language otolaryngology journals over the past decade, providing strong evidence of the increasing trend of global health as an academic pursuit within the field of otolaryngology. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

  9. Nuclear power from a long term global perspective

    Davis, D.A.

    1994-01-01

    The global problem with energy, now and into the longer term, is the same as the global problem with food. There is no absolute shortage of either and nor is there likely to be. But the pattern of availability is such that large numbers of people have inadequate supplies of one or the other, or of both. Thus, in considering global energy futures the problems are more about energy distribution than about its absolute availability: it is important that in arguing its case for expansion the nuclear industry bears that fact in mind.

  10. Global Health Governance and Global Power: A Critical Commentary on the Lancet-University of Oslo Commission Report.

    Gill, Stephen; Benatar, Solomon

    2016-01-01

    The Lancet-University of Oslo Commission Report on Global Governance for Health provides an insightful analysis of the global health inequalities that result from transnational activities consequent on what the authors call contemporary "global social norms." Our critique is that the analysis and suggested reforms to prevailing institutions and practices are confined within the perspective of the dominant-although unsustainable and inequitable-market-oriented, neoliberal development model of global capitalism. Consequently, the report both elides critical discussion of many key forms of material and political power under conditions of neoliberal development and governance that shape the nature and priorities of the global governance for health, and fails to point to the extent of changes required to sustainably improve global health. We propose that an alternative concept of progress-one grounded in history, political economy, and ecologically responsible health ethics-is sorely needed to better address challenges of global health governance in the new millennium. This might be premised on global solidarity and the "development of sustainability." We argue that the prevailing market civilization model that lies at the heart of global capitalism is being, and will further need to be, contested to avoid contradictions and dislocations associated with the commodification and privatization of health. © The Author(s) 2016.

  12. Why do they think nuclear power is origin of global warming effect?

    Fukae, Chiyokazu

    2005-01-01

    A questionnaire on nuclear power was conducted on 1500 adults in Kansai area, Japan, from October 9 to November 9, 2003. The recovery ratio was 71.0%. The results showed that 34% of them thought the nuclear power was protection of the global warming effect and 35% it was origin of the effect. It was analyzed by the logistic regression analysis method on whether the nuclear power was protection of global warming effect or not. About 43% of them recognized the nuclear power contributed to control carbon dioxide emission, and the mechanism of global warming effect. However, 35% of them did not recognize the mechanism and thought radioactive materials emission gave bad effects on the global environment. To make recognize the nuclear power is a good power source for protection of the global warming effect, the amount of reduction of carbon dioxide emission by nuclear power had to be shown. It is the shortest way for solution of the global warming problem to prove worthy of nuclear power's trust by safety and stable operation. (S.Y.)

  14. Lived experience of economic and political trends related to globalization.

    Cushon, Jennifer A; Muhajarine, Nazeem; Labonte, Ronald

    2010-01-01

    A multi-method case study examined how the economic and political processes of globalization have influenced the determinants of health among low-income children in Saskatoon, Saskatchewan, Canada. This paper presents the results from the qualitative interview component of the case study. The purpose of the interviews was to uncover the lived experience of low-income families and their children in Saskatoon with regards to political and economic trends related to globalization, an important addition to the usual globalization and health research that relies primarily on cross-country regressions in which the personal impacts remain hidden. In-depth phenomenological interviews with 26 low-income parents of young children (aged zero to five) who were residents of Saskatoon. A combination of volunteer and criterion sampling was used. Interview questions were open-ended and based upon an analytical framework. Analysis proceeded through immersion in the data, a process of open coding, and finally through a process of selective coding. The larger case study and interviews indicate that globalization has largely not been benefiting low-income parents with young children. Low-income families with young children were struggling to survive, despite the tremendous economic growth occurring in Saskatchewan and Saskatoon at the time of the interviews. This often led to participants expressing a sense of helplessness, despair, isolation, and/or anger. Respondents' experiences suggest that globalization-related changes in social conditions and public policies and programs have great potential to negatively affect family health through either psychosocial effects in individuals and/or decreased levels of social cohesion in the community.

  16. Nuclear power and related safety issues

    Valdezco, Eulinia M.

    2009-01-01

    There are a cluster of trends that reinforce the importance of nuclear power on the world scene. Energy is the essential underpinning for economic and societal progress and, as the developing world advances, the demand for energy is growing significantly. At the same time, the carbon-intensive sources of energy on which the world has traditionally relied - in particular, coal, oil, and natural gas - pose grave threats because the growing concentrations of carbon dioxide in the atmosphere will bring about climate and ocean acidification. At the same time, rising and volatile fossil fuel prices, coupled with concerns about the security of supplies of oil and gas, enhance interest in sources of energy that do not pose the same costs and risks. As an important part of the world's response to these threats, many countries are embarking on either new or expanded nuclear power programs, more commonly referred to as a nuclear renaissance. The construction of nuclear power plants is under consideration in over thirty countries that do not currently use nuclear power. For new entrants that may have experience in constructing and operating large-scale industrial and infrastructure projects, they may not be fully familiar with the unique requirements of nuclear power and may not be fully recognize the major commitments and understandings that they must assume. Additionally, an understanding of the full range of obligations may have diminished in those countries with only one or a few reactors and where nuclear construction has not been undertaken for a long time. It is therefore in the interest of all to ensure that every country with a nuclear power program has the resources, expertise, authority and capacity to assure safety in a complete and effective manner and is committed to doing so. This presentation will outline some of the more important national infrastructure considerations including nuclear safety issues for launching a nuclear power program. An update on the

  17. International cost relations in electric power generation

    Schmitt, D.; Duengen, H.; Wilhelm, M.

    1986-01-01

    In spite of the fact that analyses of the cost of electric power generation as the result of international comparative evaluations are indisputably relevant, problems pending in connection with the costs of representative power plant technologies are of the methodological bind. German authors have hitherto also been failing to clear up and consider all aspects connected with the problems of data acquisition and the adequate interpretation of results. The analysis presented by the paper abstracted therefore aims at the following: 1) Systematization of the different categories of cost relevant in connection with international comparative evaluation. Classification into different categories of decision making and development of standards meeting the requirements of international comparative evaluation. 2) Calculation of relevant average financial costs of Western German, America and French fossil-fuel and nuclear power plants by means of adequate calculation models, that is the assessment of costs with regard to countries and power plant technologies which are relevant to the Federal Republic of Germany. 3) Analysis of the resulting differences and determinantal interpretation.

  20. CCS Retrofit: Analysis of the Global Installed Power Plant Fleet

    NONE

    2012-07-01

    Electricity generation from coal is still growing rapidly and energy scenarios from the IEA expect a possible increase from today’s 1 600 GW of coal-fired power plants to over 2 600 GW until 2035. This trend will increase the lock-in of carbon intensive electricity sources, while IEA assessments show that two-thirds of total abatement from all sectors should come from the power sector alone to support a least-cost abatement strategy. Since coal-fired power plants have a fairly long lifetime, and in order to meet climate constraints, there is a need either to apply CCS retrofit to some of today’s installed coal-fired power plants once the technology becomes available. Another option would be to retire some plants before the end of their lifetime. This working paper discusses criteria relevant to differentiating between the technical, cost-effective and realistic potential for CCS retrofit. The paper then discusses today’s coal-fired power plant fleet from a statistical perspective, by looking at age, size and the expected performance of today’s plant across several countries. The working paper also highlights the growing demand for applying CCS retrofitting to the coal-fired power plant fleet of the future. In doing so this paper aims at emphasising the need for policy makers, innovators and power plant operators to quickly complete the development of the CCS technology and to identify key countries where retrofit applications will have the biggest extent and impact.

  2. Economic issues relating to power sector

    Nair, S.K.N.; Mohan, Rakesh

    1998-01-01

    Financial distress alongside high rates of growth, stagnant organizations coexistent with upgraded technologies, richly endowed regions marked by low levels of electricity consumption and the long wait for private power in face of mounting shortfalls are among the contradictions marking the power sector. Decades of public financing support could shore up the rates of growth but forms of past intervention failed to address critical institutional and regulatory issues. Key areas that need intervention have now been identified, although several are yet to be tackled. This paper discusses the more important of the problem areas holding up significant economic gains that could be realized through cost reductions, the needed levels of investments, operation of market forces and targeting of resources to promote equitable growth. The slow pace of progress is a matter for concern. Effectiveness of many of the policy initiatives of government is also dependent on providing well thought out policy supports. (author)

  5. Awareness structure of the people with opinion that nuclear power is effective for preventing global warming

    Fukae, Chiyokazu

    2006-01-01

    Most of people think that nuclear power generation is not effective for preventing global warming. In this research, the reason why people think so was investigated with using questionnaire survey. As a result, the misunderstanding, the thermal effluent and radioactive substance etc. produced from a nuclear plant promotes global warming, has influenced on this issue. People have negative image against nuclear power in the background of this idea. This negative image is a factor to decrease the evaluation that nuclear power is useful for preventing global warming regardless of the presence of the misunderstanding. By the fear that the accident of the nuclear plant brings the environmental destruction, people evaluate that nuclear power doesn't have the capabilities for environmental preservation. Especially young people have such awareness. It is necessary to learn energy and environmental issues including the merits and demerits of nuclear power objectively in the academic training.

  11. Knowledge and networks – key sources of power in global health

    Hanefeld, Johanna; Walt, Gill

    2015-01-01

    Shiffman rightly raises questions about who exercises power in global health, suggesting power is a complex concept, and the way it is exercised is often opaque. Power that is not based on financial strength but on knowledge or experience, is difficult to estimate, and yet it may provide the legitimacy to make moral claims on what is, or ought to be, on global health agendas. Twenty years ago power was exercised in a much less complex health environment. The World Health Organization (WHO) was able to exert its authority as world health leader. The landscape today is very different. Financial resources for global health are being competed for by diverse organisations, and power is diffused and somewhat hidden in such a climate, where each organization has to establish and make its own moral claims loudly and publicly. We observe two ways which allow actors to capture moral authority in global health. One, through power based on scientific knowledge and two, through procedures in the policy process, most commonly associated with the notion of broad consultation and participation. We discuss these drawing on one particular framework provided by Bourdieu, who analyses the source of actor power by focusing on different sorts of capital. Different approaches or theories to understanding power will go some way to answering the challenge Shiffman throws to health policy analysts. We need to explore much more fully where power lies in global health, and how it is exercised in order to understand underlying health agendas and claims to legitimacy made by global health actors today.

  12. Power-plant-related estuarine zooplankton studies

    Sage, L.E.; Olson, M.M.

    1981-01-01

    In-plant studies examining the effects of entrainment on zooplankton and field studies examining zooplankton abundance, composition, and distribution in the Chesapeake Bay in the vicinity of Calvert Cliffs Nuclear Power Plant have been conducted from 1974 to the present. The evolution of these studies, with particular emphasis on design and statistical treatment, is discussed. Entrainment study designs evolved from discrete sampling episodes at 4-h intervals over 24 h to a time-series sampling design in which sampling took place every 30 min over 24 and 48-h periods. The near-field study design and samping methods have included replicated net tows, using 0.5-m nets, and replicated and nonreplicated pumped sampling, using a high-speed centrifugal pump. 16 refs

  13. Global hydrobelts: improved reporting scale for water-related issues?

    Meybeck, M.; Kummu, M.; Dürr, H. H.

    2012-08-01

    Questions related to water such as its availability, water needs or stress, or management, are mapped at various resolutions at the global scale. They are reported at many scales, mostly along political or continental boundaries. As such, they ignore the fundamental heterogeneity of the hydroclimate and the natural boundaries of the river basins. Here, we describe the continental landmasses according to eight global-scale hydrobelts strictly limited by river basins, defined at a 30' (0.5°) resolution. The belts were defined and delineated, based primarily on the annual average temperature (T) and runoff (q), to maximise interbelt differences and minimise intrabelt variability. The belts were further divided into 29 hydroregions based on continental limits. This new global puzzle defines homogeneous and near-contiguous entities with similar hydrological and thermal regimes, glacial and postglacial basin histories, endorheism distribution and sensitivity to climate variations. The Mid-Latitude, Dry and Subtropical belts have northern and southern analogues and a general symmetry can be observed for T and q between them. The Boreal and Equatorial belts are unique. The hydroregions (median size 4.7 Mkm2) contrast strongly, with the average q ranging between 6 and 1393 mm yr-1 and the average T between -9.7 and +26.3 °C. Unlike the hydroclimate, the population density between the North and South belts and between the continents varies greatly, resulting in pronounced differences between the belts with analogues in both hemispheres. The population density ranges from 0.7 to 0.8 p km-2 for the North American Boreal and some Australian hydroregions to 280 p km-2 for the Asian part of the Northern Mid-Latitude belt. The combination of population densities and hydroclimate features results in very specific expressions of water-related characteristics in each of the 29 hydroregions. Our initial tests suggest that hydrobelt and hydroregion divisions are often more

    textabstractIt has been argued that power activates a general tendency to approach whereas powerlessness activates a tendency to inhibit. The assumption is that elevated power involves reward-rich environments, freedom and, as a consequence, triggers an approach-related motivational orientation and attention to rewards. In contrast, reduced power is associated with increased threat, punishment and social constraint and thereby activates inhibition-related motivation. Moreover, approach motiva...

    2013-11-01

    Full Text Available With the comprehensive advent in information and communication technologies and worldwide ease of transportation, the volume of international trade and business increased profoundly. Within this process, a Born Global Firm (BGF, right from its initiation, aims at creating competitive advantage by marketing a large volume of its products in various international markets by utilizing technological advances. Therefore, the rational behind the idea of BGF is to become an international firm in a short period of time and making international business affairs core of its business activities. Thus, the aim of this study is to review the concept of BGF theoretically and relate the issue to foreign trade affairs resting on significant sources related to the Turkish case mainly focusing on trade statistics as to review the potential development of BGFs in Turkey.

  17. Introduction of nuclear power plant for mitigating the impact of global warming

    Ida Nuryatin Finahari

    2008-01-01

    Energy utilization for power plants in Indonesia is still highly depending on the burning of fossil fuel like coal, oil, and gas. From the combustion of fossil fuel, greenhouse gases such as CO 2 and N 2 O are produced. An increase of CO 2 gas emission to the atmosphere can block the heat loss from the earth surface and will increase the greenhouse effect that results in the temperature increase of the earth surface (global warming). Global warming can cause a very extreme climate change on earth. One of the solutions to reduce CO 2 gas emission produced by fossil fuel power plants is to utilize the plants with flue gas treatment facility. At such facility, CO 2 gas is reacted with certain mineral based substances thus can be used as base material in food-, pharmaceutical-, construction-, and cosmetic industry. Another alternative to reduce CO 2 gas emission is by replacing fossil fuel power plants with nuclear power plants. Considering the environmental and economic aspects, the nuclear power plant does not emit CO 2 gas, so that the use of nuclear power plant can mitigate the impact of global warming. Based on the operational experience of nuclear power plants in advanced countries, the cost of generating electricity from nuclear power plants is more competitive than that of fossil fuel power plant.

    Naudet, G.; Capron, J.M.

    1993-01-01

    Today nuclear energy is a significant component of the electricity generation in the world; its role in the future has to be estimated as an answer to the issues concerning both energy supply and atmosphere pollution. Taking into account the lead-times observed in the energy field, the year 2020 appears a convenient time horizon to appreciate the contrast of significant differences in nuclear power expansion. The approach consists in considering one by one all the countries which have already implemented a nuclear program or could be able to launch a program before this date. However, to be clear, the results are presented according to either the five regions defined in appendix or the World Energy Council regions for comparison with the WEC results.

    Aubrecht, C.; Elvidge, C. D.; Ziskin, D.; Baugh, K. E.; Tuttle, B.; Erwin, E.; Kerle, N.

    2009-04-01

    world. Elvidge et al. (1998) first demonstrated that under certain conditions a detection of power outages is possible using OLS data. A standard procedure for visual detection of power outages has been developed. The procedure is based on identifying locations where consistently observed lighting is missing or reduced following a disaster event. Visible and thermal spectral bands of the event-related OLS data are compared to a recent cloud-free composite of nighttime lights by producing a color (RGB) composite image. For the cloud-free nighttime lights composite serving as reference information both monthly and annual composites can be used, depending on the respective availability and suitability of OLS data. The RGB color composite uses the reference lights as red (R), the current visible band as green (G) and the current thermal band as blue (B). The thermal band is typically inverted to make clouds appear bright. As clouds are typically colder than the surface of the Earth, in the thermal band higher values are observed on cloud-free areas, which thus appear brighter in standard visualization modes. The resulting color composite is visually interpreted to identify power outages, which show up as red lights on a dark (cloud-free) background. Red color stands for high values in the reference data (red band of the RGB composite) compared to low values in the event data (green and blue bands of the RGB composite), thus showing the disaster-related absence or reduction of lighting. Heavy cloud cover also obscures lights, resulting in red lights on a blue background. Yellow color in the RGB composite indicates areas where the lights are on, i.e. both red and green band (reference composite and visible band of the event image) feature high values with no cloud cover present (low values in the blue band). Under ideal conditions the presented procedure detects individual cities and towns where power has been lost or has been reduced. Conditions reducing or eliminating the

  3. Fission nuclear power prospects and its role in meeting global energy needs

    Golan, S.

    1992-01-01

    Nuclear power currently makes an important contribution to world's energy requirements providing 17% of its electricity. But as global warming becomes of greater concern, many ask whether nuclear power can and should contribute more. The author, who is involved in the nuclear power enterprise for 35 years, tries to answer this question affirmative. He holds the view that: a) nuclear fission power is essential to meeting world's energy needs without unduly impairing the global environment; b) by possessing the required attributes discussed in this paper, nuclear fission power can be made societally acceptable; c) the industrialized world should accelerate LMFR deployment while fostering more convenient energy alternatives for the developing world; and d) the HTGR is unique in its ability to augment non-electricity energy needs and could become the technology choice of developing countries for nuclear electricity production.

  4. The Global Politics of Gay Rights: The Straining Relations between the West and Africa

    Hakeem Onapajo

    2016-01-01

    Full Text Available This article analyses the contemporary global politics of gay rights as it relates to the straining relations between the Western powers and many African states that oppose sexual minorities’ rights. While the West (with emphasis on the United States, EU, and Britain advocates for the protection of gay rights in the world, Africa provides the largest concentration of states opposed to them. Therefore, there has been rising tension between both regions. This became more apparent after Nigeria and Uganda, respectively, signed their anti-gay bills into law in January and February 2014. In response to this, the Western powers decided to take some punitive measures, especially imposition of sanctions, against the countries to pressurise them to repeal their laws. In an unusual manner, the African states are radically determined to go ahead with their anti-gay laws in open defiance to the demands of the Western powers. This development, which is informed by a number of factors, shows a rather new pattern of behaviour by African states in global politics.

  5. The global climate change and its effect on power generation in Bangladesh

    Khan, Iftekhar; Alam, Firoz; Alam, Quamrul

    2013-01-01

    Frequent and intense natural calamities, sea level rises and salinity have been causing adverse impacts on economic, environmental and social aspects of hundreds of millions people across the world. Although a series of studies was undertaken on social and environment impacts, very little information is available on power generation affected by climate change. The power generation in developing countries, especially Bangladesh, whose existence is severely threatened by the rise of sea levels, salinity, the ambient temperature, drought and flood, is not well studied and reported. Therefore, the primary objective of this study was to identify the risks imposed by global climate change on existing and projected power generation in Bangladesh. The climate effect parameters and their impacts on power generation capacity are studied and analysed. The findings indicate that all existing and future power plants and their generation across the country will be affected by global climate change. - Highlights: • Analysed the future climate change impact on power generation in Bangladesh. • Projected future power generation in Bangladesh up to 2100. • Power plant in coastal areas will experience threat of inundation and salinity. • Northwest region power generation in Bangladesh will face more drought threat. • Power generation in middle region of Bangladesh will be in high risk of flood

  6. The relation between global migration and trade networks

    Sgrignoli, Paolo; Metulini, Rodolfo; Schiavo, Stefano; Riccaboni, Massimo

    2015-01-01

    In this paper we develop a methodology to analyze and compare multiple global networks, focusing our analysis on the relation between human migration and trade. First, we identify the subset of products for which the presence of a community of migrants significantly increases trade intensity, where to assure comparability across networks we apply a hypergeometric filter that lets us identify those links which intensity is significantly higher than expected. Next, proposing a new way to define country neighbors based on the most intense links in the trade network, we use spatial econometrics techniques to measure the effect of migration on international trade, while controlling for network interdependences. Overall, we find that migration significantly boosts trade across countries and we are able to identify product categories for which this effect is particularly strong.

  8. Estimation of nuclear power-related expenditures in fiscal 1982

    1981-01-01

    In fiscal 1982 (April to March, 1983), the research and development on nuclear power should be promoted actively and extensively by taking the appropriate measures. In view of the importance, the budgetary expenditures are to be estimated duly for the purpose, considering also the stringent financial situation. The budgetary expenditures for nuclear power estimated for the fiscal year 1982 are about 292,800 Million in total and the obligation act limit is about 139,900 Million. The following matters are described: nuclear power-related measures for securing nuclear power safety, promotion of nuclear power generation, establishment of the nuclear fuel cycle, development of power reactors, research on nuclear fusion, strengthening of the foundation in nuclear power research, development and utilization, promotion of international cooperation, etc.; estimated budgetary expenditures; tables of budgetary demands in various categories.

  9. The transformation of the global oil industry and its impact on international relations

    Appleyard, J.

    1994-01-01

    The transformations of ownership and control in the global oil industry since the first oil shock of 1974 are discussed and the impact of that change on several interconnected issues is explored. It is argued that structural changes in the industry affect interstate relations in ways that are of central concern to the discipline of international relations. Any likely future oil industry scenario will have considerable political and economic repercussions for both producer and consumer states, with a concommitant impact on the relations between those states more generally. There is a danger that interstate conflicts among oil producers will increase with perodic changes in the global supply and demand conditions for oil. Ways are suggested for international relations studies to take into account the change in the global oil industry and its impact on the distribution of power and on international order and justice. It is contended that a growing number of states must be considered as behaving much like firms in a competitive market, and the new international oil order both constrains and provides opportunities for those firm-like states. 20 refs

  10. The necessity of nuclear power: a global human and environmental imperative

    Ritch, J.

    Humankind cannot conceivably achieve a global clean-energy revolution without a huge expansion of nuclear power to generate electricity; to produce battery power and possibly hydrogen for tomorrow's vehicles; to desalinate seawater in response to the worlds rapidly emerging fresh-water crisis. Factors for accelerating the nuclear renaissance are: comprehensive post-Kyoto agreement all major nations, with appropriate obligations, strong political and economic incentives and goal to achieve 60% cut in global emissions by 2050; harness UN system to one clean-energy vision nuclear power at centre of global strategy; national incentive policies not for subsidy but for acceleration; education policies public's better understanding of nuclear energy new generation of nuclear professionals

    if the interpretation also takes the unequal power relation into account. Consequently, interpreting the researched in a respectful manner is difficult. This article demonstrates the necessity of increasing awareness of the unequal power relation by posing, discussing and, to some extent answering, three methodological...... questions inspired by meta-theory that are significant for qualitative research and qualitative researchers to reflect on. This article concludes that respectful interpretation and consciously paying attention to the unequal power relation in the final interpretation require decentring the subject...

  12. Tracking the global maximum power point of PV arrays under partial shading conditions

    Fennich, Meryem

    This thesis presents the theoretical and simulation studies of the global maximum power point tracking (MPPT) for photovoltaic systems under partial shading. The main goal is to track the maximum power point of the photovoltaic module so that the maximum possible power can be extracted from the photovoltaic panels. When several panels are connected in series with some of them shaded partially either due to clouds or shadows from neighboring buildings, several local maxima appear in the power vs. voltage curve. A power increment based MPPT algorithm is effective in identifying the global maximum from the several local maxima. Several existing MPPT algorithms are explored and the state-of-the-art power increment method is simulated and tested for various partial shading conditions. The current-voltage and power-voltage characteristics of the PV model are studied under different partial shading conditions, along with five different cases demonstrating how the MPPT algorithm performs when shading switches from one state to another. Each case is supplemented with simulation results. The method of tracking the Global MPP is based on controlling the DC-DC converter connected to the output of the PV array. A complete system simulation including the PV array, the direct current to direct current (DC-DC) converter and the MPPT is presented and tested using MATLAB software. The simulation results show that the MPPT algorithm works very well with the buck converter, while the boost converter needs further changes and implementation.

  13. Social power and approach-related neural activity.

    Boksem, Maarten A S; Smolders, Ruud; De Cremer, David

    2012-06-01

    It has been argued that power activates a general tendency to approach whereas powerlessness activates a tendency to inhibit. The assumption is that elevated power involves reward-rich environments, freedom and, as a consequence, triggers an approach-related motivational orientation and attention to rewards. In contrast, reduced power is associated with increased threat, punishment and social constraint and thereby activates inhibition-related motivation. Moreover, approach motivation has been found to be associated with increased relative left-sided frontal brain activity, while withdrawal motivation has been associated with increased right sided activations. We measured EEG activity while subjects engaged in a task priming either high or low social power. Results show that high social power is indeed associated with greater left-frontal brain activity compared to low social power, providing the first neural evidence for the theory that high power is associated with approach-related motivation. We propose a framework accounting for differences in both approach motivation and goal-directed behaviour associated with different levels of power.

  15. Legal Pluralism, Private Power, and the Impact of the Financial Crisis on the Global Political Economy

    Edward S. Cohen

    2013-10-01

    Full Text Available Private corporate actors have played a central role in the construction of the legal rules of globalized capitalism over the past four decades. In no sector has this been more true than in global finance, where private agents have reshaped the norms and practices of credit creation and allocation. The global financial crisis, however, has led many states to challenge aspects of this power and raised broader questions about the legitimacy and future of private power in the global legal order(s. In this paper, I argue that –while state actors have clawed back significant power in global finance– the specific powers of credit creation and allocation combined with the structural pull of transnational legal pluralism will enable major private financial institutions to retain substantial power in the face of these challenges and questions. In the process, I present some broad suggestion about how we can think about private power in the making of global commercial law. Durante las últimas cuatro décadas, actores corporativos privados han desempeñado un papel decisivo en la construcción de las normas legales del capitalismo globalizado. En ningún sector ha sido esto más cierto que en las finanzas globales, donde los agentes privados han reformado las normas y prácticas de la creación de crédito y asignación. La crisis financiera global, sin embargo, ha llevado a muchos estados a cuestionar aspectos de este poder y planteado cuestiones más amplias acerca de la legitimidad y el futuro del poder privado en el/los ordenamiento/s jurídico/s global/es. En este trabajo se sostiene que –mientras que los actores estatales han recuperado un poder significativo en las finanzas globales– los poderes específicos de la creación de crédito y asignación combinados con la fuerza estructural del pluralismo jurídico transnacional permitirán a las principales instituciones financieras privadas retener poder sustancial ante estos retos y preguntas

  16. Global analysis of small molecule binding to related protein targets.

    Felix A Kruger

    2012-01-01

    Full Text Available We report on the integration of pharmacological data and homology information for a large scale analysis of small molecule binding to related targets. Differences in small molecule binding have been assessed for curated pairs of human to rat orthologs and also for recently diverged human paralogs. Our analysis shows that in general, small molecule binding is conserved for pairs of human to rat orthologs. Using statistical tests, we identified a small number of cases where small molecule binding is different between human and rat, some of which had previously been reported in the literature. Knowledge of species specific pharmacology can be advantageous for drug discovery, where rats are frequently used as a model system. For human paralogs, we demonstrate a global correlation between sequence identity and the binding of small molecules with equivalent affinity. Our findings provide an initial general model relating small molecule binding and sequence divergence, containing the foundations for a general model to anticipate and predict within-target-family selectivity.

  17. University students' understanding level about words related to nuclear power

    Oiso, Shinichi; Watabe, Motoki

    2012-01-01

    The authors conducted a survey of university students' understanding level about words related to nuclear power before and after Fukushima Daiichi Power Plant accident, and analyzed the difference between before and after the accident. The results show that university students' understanding level improved after the accident, especially in the case of reported words by mass media. Understanding level of some nuclear power security words which were not reported so much by mass media also improved. That may be caused by rising of people's concern about nuclear power generation after the accident, and there is a possibility that the accident motivated people to access such words via internet, journals, etc. (author)

  18. The global existence problem and cosmic censorship in general relativity

    Moncrief, V.; Eardley, D.M.

    1981-01-01

    Two global existence conjectures for the Einstein equations are formulated and their relevance to the cosmic censorship conjecture discussed. It is argued that the reformulation of the cosmic censorship conjecture as a global existence problem renders it more amenable to direct analytical attack. To demonstrate the facility of this approach the cosmological version of the global existence conjecture is proved for the Gowdy spacetimes on T 3 X R. (author)

  19. Global income-related inequalities in HIV testing.

    Larose, Auburn; Moore, Spencer; Harper, Sam; Lynch, John

    2011-09-01

    Voluntary counseling and testing (VCT) is an important prevention initiative in reducing HIV/AIDS transmission. Despite current global prevention efforts, many low- and middle-income countries continue reporting low VCT levels. Little is known about the association of within- and between-country socioeconomic inequalities and VCT. Based on the 'inverse equity hypothesis,' this study examines the degree to which low socioeconomic groups in developing countries are disadvantaged in VCT. Using recently released data from the 2002 to 2003 World Health Survey (WHS) for 106 705 individuals in 49 countries, this study used multilevel logistic regression to examine the association of individual- and national-level factors with VCT, and whether national economic development moderated the association between individual income and VCT. Individual income was based on country-specific income quintiles. National economic development was based on national gross domestic product per capita (GDP/c). Effect modification was evaluated with the likelihood ratio test (G(2)). Individuals eligible for the VCT question of the WHS were adults between the ages of 18-49 years; women who had given birth in the last 2 years were excluded from this question. VCT was more likely among higher income quintiles and in countries with higher GDP/c. GDP/c moderated the association between individual income and VCT whereby relative income differences in VCT were greater in countries with lower GDP/c (G(2)= 9.21; P= 0.002). Individual socio-demographic characteristics were also associated with the likelihood of a person having VCT. Relative socioeconomic inequalities in VCT coverage appear to decline when higher SES groups reach a certain level of coverage. These findings suggest that changes to international VCT programs may be necessary to moderate the relative VCT differences between high- and low-income individuals in lower GDP/c nations.

  20. Accounts from the field: a public relations perspective on global AIDS/HIV.

    Bardhan, Nilanjana R

    2002-01-01

    This study is a theoretical as well as empirical exploration of the power and cultural differentials that mark and construct various intersecting discourses, specifically media discourse, on global AIDS/HIV. It applies the language and concepts of public relations to understand how the press coverage of the pandemic is associated with the variables that impact the newsmaking process as well as the public and policy implications of macro news frames generated over time. Theoretical work in the areas of agenda setting and news framing also instruct the conceptual framework of this analysis. Narrative analysis is used as a methodology to qualitatively analyze three pools of accounts-from people either living with AIDS/HIV, involved in AIDS/HIV work, or discursively engaged in the media construction of the pandemic; from transnational wire service journalists who cover the issue at global and regional levels; and policy shapers and communicators who are active at the global level. These three communities of respondents represent important stakeholders in the AIDS/HIV issue. The findings are analyzed from a public relations standpoint. Perhaps the most important finding of this study is that the public relations approaches used to address AIDS/HIV related issues need to be grounded in context-specific research and communicative practices that bring out the lived realities of AIDS/HIV at grassroots levels. The findings also posit that those situated at critical junctions between various stakeholders need to cultivate a finely balanced understanding of the etic and emic intersections and subjectivities of global/local AIDS/HIV.

  1. A relational approach to durable poverty, inequality and power.

    Mosse, David

    2010-01-01

    The article argues for what can be called a 'relational' approach to poverty: one that first views persistent poverty as the consequence of historically developed economic and political relations, and second, that emphasises poverty and inequality as an effect of social categorisation and identity, drawing in particular on the experience of adivasis ("tribals") and dalits ("untouchables") subordinated in Indian society. The approach follows Charles Tilly's Durable Inequality in combining Marxian ideas of exploitation and dispossession with Weberian notions of social closure. The article then draws on the work of Steven Lukes, Pierre Bourdieu and Arjun Appadurai to argue for the need to incorporate a multidimensional conception of power; including not only power as the direct assertion of will but also 'agenda-setting power' that sets the terms in which poverty becomes (or fails to become) politicised, and closely related to power as political representation. This sets the basis for discussion of the politics of poverty and exclusion.

    The galaxy integrated Hα star formation rate–stellar mass relation, or SFR(global)–M *(global) relation, is crucial for understanding star formation history and evolution of galaxies. However, many studies have dealt with SFR using unresolved measurements, which makes it difficult to separate out the contamination from other ionizing sources, such as active galactic nuclei and evolved stars. Using the integral field spectroscopic observations from SDSS-IV MaNGA, we spatially disentangle the contribution from different Hα powering sources for ∼1000 galaxies. We find that, when including regions dominated by all ionizing sources in galaxies, the spatially resolved relation between Hα surface density (ΣHα (all)) and stellar mass surface density (Σ*(all)) progressively turns over at the high Σ*(all) end for increasing M *(global) and/or bulge dominance (bulge-to-total light ratio, B/T). This in turn leads to the flattening of the integrated Hα(global)–M *(global) relation in the literature. By contrast, there is no noticeable flattening in both integrated Hα(H II)–M *(H II) and spatially resolved ΣHα (H II)–Σ*(H II) relations when only regions where star formation dominates the ionization are considered. In other words, the flattening can be attributed to the increasing regions powered by non-star-formation sources, which generally have lower ionizing ability than star formation. An analysis of the fractional contribution of non-star-formation sources to total Hα luminosity of a galaxy suggests a decreasing role of star formation as an ionizing source toward high-mass, high-B/T galaxies and bulge regions. This result indicates that the appearance of the galaxy integrated SFR–M * relation critically depends on their global properties (M *(global) and B/T) and relative abundances of various ionizing sources within the galaxies.

  6. Relations of power in public schools: a case study

    Maria Custódia Jorge Rocha

    2014-04-01

    Full Text Available In this paper, based on a few authors who see power as a substantive element – instituted power – and others who consider it as an action verb – instituting power (ROCHA, 2007 –, highlighting some types of power relevant in sociological and organizational research on schools, we present empirical data and institutional discourses, enabled by a case study of qualitative nature. Thus, we can say that relations of power in schools both allow the strengthening of hierarchical and asymmetrical relations of power that exist between institutional players and enable the creation of new “circles of power” that can be promptly activated or can be object of a modernization process held in a more or less generalized manner. This may be reinforced and introduced to players/students, our main target of study, as the most legitimate object, superseding all others but not canceling them. The key objective is to present school organization as a highly complex environment, especially when considered in the light of the multiple and cumulative relations of power that emerge and are materialized.

  7. The future of nuclear power worldwide and the role of the global nuclear energy partnership

    Spurgeon, D.R.

    2008-01-01

    This presentation is entitled, 'The Future of Nuclear Power Worldwide and the Role of the Global Nuclear Energy Partnership', and the core message in one sentence is: When we look at the challenges of meeting our growing energy demands, providing for energy security and reducing greenhouse gas emissions, we must conclude that nuclear power has to play a significant and growing role in meeting these challenges. Similarly, the mission of the Global Nuclear Energy Partnership is to foster the safe and secure worldwide expansion of nuclear energy. GNEP comes at a crucial time in the burgeoning expansion of nuclear power. It is the only comprehensive proposal to close the nuclear fuel cycle in the United States, and engage the international community to minimize proliferation risks as well as provide and benefit from cooperation in policy formation, technical support, and technology and infrastructure development. Nuclear power's poised renaissance is encouraging, but it will require public support, expanded R and D activities and facilities, and increases in human capital needed for wide-scale construction and operation of new nuclear plants. Despite recent political currents, Germany can, too, become a part of this renaissance and become a full partner in the global partnership that shares a common vision for nuclear power's expansion.

    In this paper, we try to show how the EU became a global ecological power, i.e. a power that influences environmental policies throughout the world. While the existing literature stresses the significance of normative power, regulatory politics and multi-level governance in this process, we highlight the importance of what we call the logics of market integration. By that we mean the decisive role of Single market integration in fostering convergence of environmental policies at the European level as well as in extending European influence at the global level. We illustrate our approach with the case of climate policy, detailing the EU's influence on economic instruments developed worldwide to mitigate climate change. (authors)

    consistently declining by approximately 2% per annum. There is, however, a lack of information from low HDI countries where screening is less likely to have been successfully implemented. Estimates of the projected incidence of cervical cancer in 2030, based solely on demographic factors, indicate a 2% increase in the global burden of cervical cancer, i.e., in balance with the current rate of decline. Due to the relative small numbers involved, it is difficult to discern temporal trends for the other cancers associated with HPV infection. Genital warts represent a sexually transmitted benign condition caused by HPV infection, especially HPV6 and HPV11. Reliable surveillance figures are difficult to obtain but data from developed countries indicate an annual incidence of 0.1 to 0.2% with a peak occurring at teenage and young adult ages.

  12. Power station design and public relations - association with the citizen

    Eiteneyer, H.

    1977-01-01

    The series of questions concerning public relations, connected with the realization of power plant construction projects will be discussed before the background of the public requirement of electricity supply corporations. It will be explained that public relation cannot be seen as an instrument, having the purpose to inform about 'good or bad' of power plant designs and construction intentions. PR is more a constitutive element of economy policy. Transparent, clear information of the citizen about power plant projects, and power plant related procedures should be their targets. This signifies a distance from just technical presentation. PR must develop in the direction to active corporational strategy, taking psychological- and social psychological influences into consideration. Statements will be made in regard to the dialogue between power plant advocates and power plant opponents. The special responsibility of the public electricity supply corporations for an always sufficient, safe and economical supply to the consumer, will be pointed out. Better information of the public in this regard is a necessary requirement. (orig.) [de

  13. Status, Power, and Intergroup Relations: The Personal Is the Societal.

    Fiske, Susan T; Dupree, Cydney H; Nicolas, Gandalf; Swencionis, Jillian K

    2016-10-01

    Hierarchies in the correlated forms of power (resources) and status (prestige) are constants that organize human societies. This article reviews relevant social psychological literature and identifies several converging results concerning power and status. Whether rank is chronically possessed or temporarily embodied, higher ranks create psychological distance from others, allow agency by the higher ranked, and exact deference from the lower ranked. Beliefs that status entails competence are essentially universal. Interpersonal interactions create warmth-competence compensatory tradeoffs. Along with societal structures (enduring inequality), these tradeoffs reinforce status-competence beliefs. Race, class, and gender further illustrate these dynamics. Although status systems are resilient, they can shift, and understanding those change processes is an important direction for future research, as global demographic changes disrupt existing hierarchies.

  14. With power comes responsibility: motorcycle engine power and power-to-weight ratio in relation to accident risk.

    Mattsson, Markus; Summala, Heikki

    2010-02-01

    Current European legislation allows the EU member states to restrict the maximum power output of motorcycles to 74 kW even though evidence supporting the limit is scarce and has produced mixed results-perhaps because motorcycle performance has been measured by engine displacement, not engine power, in most of the previous studies. This study investigates the relationship of motorcycle engine power and power-to-weight ratio to risk of fatal and nonfatal crashes in Finland. The fatality rate (number of fatal accidents/number of registered motorbikes) for riders of different ages riding bikes belonging to different power and power-to-weight ratio classes was examined using a comprehensive in-depth database. Data on nonfatal accidents were acquired from a Web questionnaire (N = 2708), which also served as a basis for estimating riders' annual mileage. Mileage data allowed the calculation of accident risk per kilometer ridden for bikes differing in power and power-to-weight ratio. The fatality risk per number of registered motorcycles and per kilometer ridden increases both with power and power-to-weight ratio, independently of rider's age. No relationship between performance and risk of a less severe crash was found. The pre-accident speed of the most powerful bikes was 20 km/h or more over the speed limit in a large proportion of the fatal accidents (odds ratio = 4.8 for > 75 kW motorbikes; odds ratio = 6.2 for > 0.3 kW/kg motorbikes). The risk of being involved in a fatal crash is higher among the riders of powerful motorcycles. However, it is not clear whether the results are related to the riding habits of the riders that choose the most powerful bikes available or whether the high risk is due to the properties of the bikes themselves. Therefore, further research is needed before considering legal limits on motorcycle performance.

  17. Safety issues relating to the design of fusion power facilities

    Stasko, R.R.; Wong, K.Y.; Russell, S.B.

    1986-06-01

    In order to make fusion power a viable future source of energy, it will be necessary to ensure that the cost of power for fusion electric generation is competitive with advanced fission concepts. In addition, fusion power will have to live up to its original promise of being a more radiologically benign technology than fission, and be able to demonstrate excellent operational safety performance. These two requirements are interrelated, since the selection of an appropriate safety philosophy early in the design phase could greatly reduce or eliminate the capital costs of elaborate safety related and protective sytems. This paper will briefly overview a few of the key safety issues presently recognized as critical to the ultimate achievement of licensable, environmentally safe and socially acceptable fusion power facilities. 12 refs

  18. A Power Efficient Exaflop Computer Design for Global Cloud System Resolving Climate Models.

    Wehner, M. F.; Oliker, L.; Shalf, J.

    2008-12-01

    Exascale computers would allow routine ensemble modeling of the global climate system at the cloud system resolving scale. Power and cost requirements of traditional architecture systems are likely to delay such capability for many years. We present an alternative route to the exascale using embedded processor technology to design a system optimized for ultra high resolution climate modeling. These power efficient processors, used in consumer electronic devices such as mobile phones, portable music players, cameras, etc., can be tailored to the specific needs of scientific computing. We project that a system capable of integrating a kilometer scale climate model a thousand times faster than real time could be designed and built in a five year time scale for US$75M with a power consumption of 3MW. This is cheaper, more power efficient and sooner than any other existing technology.

  19. The Emergence of `Power with': The Case of a Born Global Organization

    Yan, Lin; Panteli, Niki

    Thanks to the advancement of Information and Communications Technologies, the past decade has seen the rise of Born Global organizations (Rennie, 1993; Oviatt and McDougall, 1994; Karra and Philips, 2004; Zahra, 2005). Broadly defined as ‘business organizations that, right from inception, seek to derive significant competitive advantages from the use of resources and the sales of outputs in multiple countries’ (Oviatt and McDougall, 1994: 49), Born Global organizations are small, young, and internationally dispersed. While sharing the characteristics of ‘smallness’ and ‘newness’ of Small- and Medium-sized Enterprises (SMEs), Born Global organizations also bear ‘foreignness’, similar to that of Multinational Corporations (Zahra, 2005). Born Globals therefore need to strike a balance between ‘global reach’ and ‘local touch’ as in Multinational Corporations (Bartlett and Ghoshal, 1989); yet they have to do so with scare resources and organizational uncertainty similar to SMEs, and with ‘lean’ and ‘mean’ communications afforded by ICT (e.g. Sproull and Kiesler, 1986). This study is an initial attempt to untangle the combined challenges in Born Globals’ innovative way of management. Through a longitudinal case study, we aim to explore the issue of power in a Born Global’s endeavour to manage its global knowledge via technology mediation.

  20. Power Deals. Mergers and acquisitions activity within the global electricity and gas market. 2010 Annual Review

    NONE

    2011-02-15

    The global power deal market is finally seeing an upward trend in momentum from the lows reached in 2009, with the total deal value in the non-renewable electricity and gas sectors up 19% year on year from USD 97.6bn to USD 116bn in 2010 - a year which also saw an end to the deal stalemate in the US with a renewed deal flow that looks set to continue this year. Compared to the heady mountain of power deals transacted between 2005-2008, deal values remain low but conditions are in place for a return at least to the foothills of these peaks, according to PwC's annual Power Deals review. Globalisation of the power sector is moving forward on a number of fronts with, for example, companies looking at gaining a larger presence in growth markets, acquisitions of global network asset portfolios with strong international interest in infrastructure assets and signs of greater Chinese involvement, not just from grid companies but also independent power producers.

    It is shown that there exists a family of coordinate systems in which the energy-momentum tensor is globally conserved. Furthermore, this preferred class of frames includes geodesic systems with respect to any arbitrary point or timelike geodesic line. This implies a physically satisfactory conservation law with no need to introduce an extraneous pseudotensor

  8. Roles of nuclear power system in the presence of uncertainties from global warming

    Kiriyama, Eriko; Iwata, Shuichi

    2005-01-01

    Environmental 'bads' like carbon dioxide are not simply incorporated in the market system. The costs involved, however, do not really reflect the inherent value of the environment, or what it is worth to them. This study focuses on the uncertainty of CO 2 emission credits. Assigning economic values to environmental goods and services is complex, but it is an area that is receiving considerable attention from environmental economists. The purpose of this study is to analyze the value of an investment in power generation assets that do not emit CO 2 . To deal with the CO 2 emission credit, we built new models based on the real option model by Pindyck (2000). In the modern, market-based financial systems that dominate the global economy, the value of a resource is represented by the price that an individual or a group is willing to pay for it. Managing CO 2 emission limitations will be a critical aspect of power generation systems. And it will be increasingly so as the emphasis on global environmental issues continues to rise. In order to secure the effectiveness of measures against global warming, we should reconsider the role of nuclear power systems. (author)

  10. Ownership relations and cooperation in the Norwegian power market

    Singh, Balbir; Skjeret, Frode

    2006-01-01

    The Norwegian Competition Authority (KT) under a grant from The Ministry for Government Administration and Reform (FAD) commissioned a study in December 2005 to outline the extent and nature of cooperation among the power production companies in the Norwegian Power market. The main objective of the study was to establish an updated data set that documents the status with respect to distribution of ownership of generation capacity, and to identify the main forms of cooperation and information exchange among the power generation companies in Norway. Both secondary and primary sources have been used in the study. Data related to the distribution of generation capacity is mainly based on secondary sources and covers the total population consisting of 622 power plants and 183 companies in the Norwegian power market. In addition, requests for information were sent to a sample of power companies to collect primary information that could shed light on the status, trend, motivations, behavioral constraints, and exchange of information associated with different forms of cooperation between the power producers. The complete data set and results are modeled in a spread sheet based database (OPS) that accompanies this report. This report summarizes the main findings of the study. The primary data collected from the power companies during the sample survey is not included in this report. Only the main conclusions drawn on the basis of the analysis of the information provided by the respondents are presented in this report. It is important to emphasize that this publication reports data and information as collected from the primary and secondary sources in this project. The material presented in this publication reports a summary of the collected information and is not meant to draw any conclusions about the existence or otherwise of any form of collusion among the responding companies (author) (ml)

  11. Power and Politics in the Global Health Landscape: Beliefs, Competition and Negotiation Among Global Advocacy Coalitions in the Policy-Making Process.

    McDougall, Lori

    2016-01-30

    Advocacy coalitions play an increasingly prominent role within the global health landscape, linking actors and institutions to attract political attention and resources. This paper examines how coalitions negotiate among themselves and exercise hidden forms of power to produce policy on the basis of their beliefs and strategic interests. This paper examines the beliefs and behaviours of health advocacy coalitions using Sabatier's Advocacy Coalition Framework (ACF) as an informal theoretical lens. Coalitions are further explored in relation to the concept of transnational advocacy networks (Keck and Sikkink) and of productive power (Shiffman). The ACF focuses on explaining how policy change takes place when there is conflict concerning goals and technical approaches among different actors. This study uses participant observation methods, self-reported survey results and semi-structured qualitative interviews to trace how a major policy project of the Millennium Development Goal (MDG) era, the Global Strategy for Women's and Children's Health, was constructed through negotiations among maternal, newborn, and child health (MNCH) and sexual and reproductive health and rights (SRHR) advocacy coalitions. The Global Strategy represented a new opportunity for high-level political attention. Despite differing policy beliefs, MNCH and SRHR actors collaborated to produce this strategy because of anticipated gains in political attention. While core beliefs did not shift fundamentally and collaboration was primarily a short-term tactical response to a time-bound opportunity, MNCH actors began to focus more on human rights perspectives and SRHR actors adopted greater use of quantifiable indicators and economic argumentation. This shift emphasises the inherent importance of SRHR to maternal and child health survival. As opportunities arise, coalitions respond based on principles and policy beliefs, as well as to perceptions of advantage. Global health policy-making is an arena of

  19. The Power Reconfiguration and Global Governance with and Without Government: A View on The New Actors

    Giovanni Olsson

    2015-12-01

    Full Text Available This article aims to address the reconfiguration of the exercise of power and governance by new international actors. Initially, the power is identified in both conflictual relations as in consensual, presenting him with a bifronte categorization: power on and power to. Still, it is the conceptual shift that involves governance, showing that the authority may be exercised independently of the will of States, presenting it as governance with and without government. Finally, it is shown that the new players, especially non-governmental organizations and transnational corporations exert significant role in the political landscape of contemporary international society, whose national borders have every day lost importance.

  1. Globalization, Transnational Crime and State Power: The Need for a New Criminology

    Viano Emilio C.

    2010-03-01

    Full Text Available This paper focuses on globalization as it relates to transnational crime. It attempts to show how the very patterns and dynamics that make globalization possible and effective as a positive force in the world also give rise to “collateral” negative, that is criminal, consequences and facilitate the spawning and rapid growth of transnational crimes. Moreover, there are also crimes committed opposing globalization. And globalization also makes it easier to fight crime since it facilitates cooperation and coordination of anti-crime efforts. Thus it has a complex relationship with crime: positive, negative and preventative. The paper also addresses how criminologists should review and revise their research and intervention models to take into account how globalization has changed the way we can and should approach crime. It addresses the lack of criminological interest in the “crimes” of globalization. It challenges the essentialist assumption of mainstream criminology that the legal definitions of crime are sacrosanct and frozen. We need a broader conceptualization of crime which goes beyond the prescriptions of criminal law and draws on different intellectual traditions (crimes of globalization, structural violence and the critique of neo-liberalism which emphasize the contingent influence of social harm in people's life choices. New and bold ways of thinking and modeling are needed. Examples are provided.

  2. Power relations and reciprocity: dialectics of knowledge construction.

    Ben-Ari, Adital; Enosh, Guy

    2013-03-01

    In this article we suggest a theoretical framework of knowledge construction by employing the concept of dialectics to power relationships between researcher and participants. Power distribution in research is perceived as dichotomous and asymmetrical in favor of the researcher, creating unequal power relations that make exploitation possible. Acknowledging such exploitation has led to a critical stance and attempts to bridge gaps through egalitarianism and empowerment of participants. Some scholars have focused on shifting expert knowledge differentials between researcher and participants throughout the research project. Others have evaluated such gaps as a source of knowledge construction. In the present work we applied a dialectical approach to understanding research relationships, suggesting reciprocity as their defining attribute, regardless of symmetry or asymmetry and as a source of knowledge construction. In this article we recommend avoiding a taken-for-granted attitude, because we see it as a direct obstacle to the construction of knowledge.

  3. Nuclear position in power generation sector - under the pressure of anti-global warming and power market reform

    Hayashi, Taizo

    2005-01-01

    The future structure surrounding fuel choice in power generation sector should be understood how to evaluate actual and potential merit and demerit both in economic and environmental aspects on nuclear power generation. That is i.e. nuclear can be understood as superior power source without GHGs and on the other hand, as unfavorable power source which might cause some critical dangers due to its hazardous radioactive nuclear waste. On this specific characteristic, this theme on fuel choice surrounding nuclear in power generation sector could be understood as a highly cultural problem as much as economic and political one. For instance, we can observe quite opposite direction with each other on nuclear power development in European countries like France and Finland on one hand and Germany and Sweden on the other hand. Looking at Asian countries, we also observe the very reality of high economic growth with rapid growth of electricity demand like China. What on earth, is it really possible without nuclear power source for such gigantic countries. I will develop my personal idea on nuclear power source based on Japanese experience towards successfully managing nuclear power technologies in the world, consisting of developing countries with growing economies and of advanced ones with rather matured nuclear technology under the pressure of environmentally restricted world order. My basic view point to discuss nuclear power problem has, conclusionally speaking, several aspects; The first one is in the relation with deregulation or liberalization of electricity market, which has been undergoing among such developed countries as OECD member countries i.e. USA, EU, Japan and other countries. Deregulation or liberalization of electricity market seems to be the inevitable process towards more matured market economy among developed countries group, and that process inevitably forces management of power companies towards more near sighted attitude if those companies are

    Japanese government has issued action program so called {open_quotes}Action Program to Arrest Global Warming{close_quotes} for preventing global warming at Oct., 1990. According to the program, CO{sub 2} emission should be stabilized on a per capita basis in the year 2000 and beyond at about same level as in 2000 by introducing several methods such as energy conservation, improvement of energy using efficiency, expanding use of renewable energy and so on. The basic concept, target and methods are summarized. At the same time, MITI published so called {open_quotes}New Earth 21{close_quotes} project which aims remedying the earth environment modified by human activities since industrial innovation began at about 200 years ago in coming 100 years. This plan proposed yearly step of research development of technology for mitigating CO{sub 2} emission. According to the MITI`s plan, 15 institutions belonging to AIST have carrying research for developing technology of reducing emission of CO{sub 2} and other greenhouse gases, with cooperation of other research organizations such as RITE (research Institute of Innovative Technology for Earth) and NEDO (New Energy and Industrial Technology Developing Organization). Time schedule of the research development by The New Earth 21 project is summarized in Table 2. Now, in Japan, many national institutions and universities, research works relating reduction and mitigation of GHG are carried out according to this guideline.

    Full Text Available Abstract Background 'Innovation' has become a policy focus in its own right in many states as they compete to position themselves in the emerging knowledge economies. Innovation in biomedicine is a global enterprise in which 'Rising Power' states figure prominently, and which undoubtedly will re-shape health systems and health economies globally. Scientific and technological innovation processes and policies raise difficult issues in the domains of science/technology, civil society, and the economic and healthcare marketplace. The production of knowledge in these fields is complex, uncertain, inter-disciplinary and inter-institutional, and subject to a continuing political struggle for advantage.

  7. Global Thermal Power Plants Database: Unit-Based CO2, SO2, NOX and PM2.5 Emissions in 2010

    Tong, D.; Qiang, Z.; Davis, S. J.

    2016-12-01

    There are more than 30,000 thermal power plants now operating worldwide, reflecting a tremendously diverse infrastructure that includes units burning oil, natural gas, coal and biomass and ranging in capacity from 1GW. Although the electricity generated by this infrastructure is vital to economic activities across the world, it also produces more CO2 and air pollution emissions than any other industry sector. Here we present a new database of global thermal power-generating units and their emissions as of 2010, GPED (Global Power Emissions Database), including the detailed unit information of installed capacity, operation year, geographic location, fuel type and control measures for more than 70000 units. In this study, we have compiled, combined, and harmonized the available underlying data related to thermal power-generating units (e.g. eGRID of USA, CPED of China and published Indian power plants database), and then analyzed the generating capacity, capacity factor, fuel type, age, location, and installed pollution-control technology in order to determine those units with disproportionately high levels of emissions. In total, this work is of great importance for improving spatial distribution of global thermal power plants emissions and exploring their environmental impacts at global scale.

  11. Incorporating global warming risks in power sector planning: A case study of the New England region

    Krause, F.; Busch, J.; Koomey, J.

    1992-11-01

    Growing international concern over the threat of global climate change has led to proposals to buy insurance against this threat by reducing emissions of carbon (short for carbon dioxide) and other greenhouse gases below current levels. Concern over these and other, non-climatic environmental effects of electricity generation has led a number of states to adopt or explore new mechanisms for incorporating environmental externalities in utility resource planning. For example, the New York and Massachusetts utility commissions have adopted monetized surcharges (or adders) to induce emission reductions of federally regulated air pollutants (notably, SO 2 , NO x , and particulates) beyond federally mandated levels. These regulations also include preliminary estimates of the cost of reducing carbon emissions, for which no federal regulations exist at this time. Within New England, regulators and utilities have also held several workshops and meetings to discuss alternative methods of incorporating externalities as well as the feasibility of regional approaches. This study examines the potential for reduced carbon emissions in the New England power sector as well as the cost and rate impacts of two policy approaches: environmental externality surcharges and a target- based approach. We analyze the following questions: Does New England have sufficient low-carbon resources to achieve significant reductions (10% to 20% below current levels) in fossil carbon emissions in its utility sector? What reductions could be achieved at a maximum? What is the expected cost of carbon reductions as a function of the reduction goal? How would carbon reduction strategies affect electricity rates? How effective are environmental externality cost surcharges as an instrument in bringing about carbon reductions? To what extent could the minimization of total electricity costs alone result in carbon reductions relative to conventional resource plans?

    Full Text Available Gorik Ooms recently made a strong case for considering the centrality of normative premises to analyzing and understanding the underappreciated importance of the nexus of politics, power and process in global health. This critical commentary raises serious questions for the practice and study of global health and global health governance. First and foremost, this commentary underlines the importance of the question of what is global health, and why as well as how does this definition matter? This refocuses discussion on the importance of definitions and how they wield power. It also re-affirms the necessity of a deeper analysis and understanding of power and how it affects and shapes the practice of global health.

  13. Steady-state global optimization of metabolic non-linear dynamic models through recasting into power-law canonical models.

    Pozo, Carlos; Marín-Sanguino, Alberto; Alves, Rui; Guillén-Gosálbez, Gonzalo; Jiménez, Laureano; Sorribas, Albert

    2011-08-25

    Design of newly engineered microbial strains for biotechnological purposes would greatly benefit from the development of realistic mathematical models for the processes to be optimized. Such models can then be analyzed and, with the development and application of appropriate optimization techniques, one could identify the modifications that need to be made to the organism in order to achieve the desired biotechnological goal. As appropriate models to perform such an analysis are necessarily non-linear and typically non-convex, finding their global optimum is a challenging task. Canonical modeling techniques, such as Generalized Mass Action (GMA) models based on the power-law formalism, offer a possible solution to this problem because they have a mathematical structure that enables the development of specific algorithms for global optimization. Based on the GMA canonical representation, we have developed in previous works a highly efficient optimization algorithm and a set of related strategies for understanding the evolution of adaptive responses in cellular metabolism. Here, we explore the possibility of recasting kinetic non-linear models into an equivalent GMA model, so that global optimization on the recast GMA model can be performed. With this technique, optimization is greatly facilitated and the results are transposable to the original non-linear problem. This procedure is straightforward for a particular class of non-linear models known as Saturable and Cooperative (SC) models that extend the power-law formalism to deal with saturation and cooperativity. Our results show that recasting non-linear kinetic models into GMA models is indeed an appropriate strategy that helps overcoming some of the numerical difficulties that arise during the global optimization task.

  14. Steady-state global optimization of metabolic non-linear dynamic models through recasting into power-law canonical models

    2011-08-01

    Full Text Available Abstract Background Design of newly engineered microbial strains for biotechnological purposes would greatly benefit from the development of realistic mathematical models for the processes to be optimized. Such models can then be analyzed and, with the development and application of appropriate optimization techniques, one could identify the modifications that need to be made to the organism in order to achieve the desired biotechnological goal. As appropriate models to perform such an analysis are necessarily non-linear and typically non-convex, finding their global optimum is a challenging task. Canonical modeling techniques, such as Generalized Mass Action (GMA models based on the power-law formalism, offer a possible solution to this problem because they have a mathematical structure that enables the development of specific algorithms for global optimization. Results Based on the GMA canonical representation, we have developed in previous works a highly efficient optimization algorithm and a set of related strategies for understanding the evolution of adaptive responses in cellular metabolism. Here, we explore the possibility of recasting kinetic non-linear models into an equivalent GMA model, so that global optimization on the recast GMA model can be performed. With this technique, optimization is greatly facilitated and the results are transposable to the original non-linear problem. This procedure is straightforward for a particular class of non-linear models known as Saturable and Cooperative (SC models that extend the power-law formalism to deal with saturation and cooperativity. Conclusions Our results show that recasting non-linear kinetic models into GMA models is indeed an appropriate strategy that helps overcoming some of the numerical difficulties that arise during the global optimization task.

  15. CHANGE MANAGEMENT STRATEGIES RELATED TO THE GLOBAL ENVIRONMENT COMPLEXITY

    Elena DOVAL

    2016-12-01

    Full Text Available The changes in organizations appear as a reaction to the organizational environment changes. In order to manage these changes successfully, the managers need to anticipate and design alternative strategies by preparing different options.  Nevertheless, the complexity of the global environment forces the managers to adopt strategies for their organizations that are facilitating the creation of new strategic competences and competitive advantages to face the environmental rapid changes. In this context, this paper is aiming to illustrate the main directions the change management may consider to change the organization strategies in order to harmonize them to the external environment, such as: integration versus externalization, flexible specialization and flexible organization, standardization versus adaptation, market segmentation, relationship building and maintaining and communication integration.  However, the new strategies are based on a changed attitude of the managers towards the competitive advantage that is dynamic and focused on creation rather then to operations.

  19. An International Relations perspective on the global politics of carbon dioxide capture and storage

    De Coninck, H. [Energy research Centre of the Netherlands ECN, Unit Policy Studies, Radarweg 60, 1043 NT Amsterdam (Netherlands); Baeckstrand, K. [Department of Political Science, Lund University, P.O. Box 52, 221 00 Lund (Sweden)

    2011-05-15

    With the publication of the IPCC Special Report on Carbon dioxide Capture and Storage (CCS), CCS has emerged as a focal issue in international climate diplomacy and energy collaboration. This paper has two goals. The first goal is to map CCS activities in and among various types of intergovernmental organisations; the second goal is to apply International Relations (IR) theories to explain the growing diversity, overlap and fragmentation of international organisations dealing with CCS. Which international organisations embrace CCS, and which refrain from discussing it at all? What role do these institutions play in bringing CCS forward? Why is international collaboration on CCS so fragmented and weak? We utilise realism, liberal institutionalism and constructivism to provide three different interpretations of the complex global landscape of CCS governance in the context of the similarly complicated architecture of global climate policy. A realist account of CCS's fragmented international politics is power driven. International fossil fuel and energy organisations, dominated by major emitter states, take an active role in CCS. An interest-based approach, such as liberal institutionalism, claims that CCS is part of a 'regime complex' rather than an integrated, hierarchical, comprehensive and international regime. Such a regime complex is exemplified by the plethora of international organisations with a role in CCS. Finally, constructivism moves beyond material and interest-based interpretations of the evolution of the institutionally fragmented architecture of global CCS governance. The 2005 IPCC Special Report on CCS demonstrates the pivotal role that ideas, norms and scientific knowledge have played in transforming the preferences of the international climate-change policy community.

  20. Energy-Water-Land Nexus: The relative contributions of climate and human systems on global water scarcity

    2017-12-01

    There is a growing consensus that energy, water, and land systems are interconnected and should be analyzed as such. New tools are required to represent the interactions between population, economic growth, energy, land, and water resources in a dynamically evolving system. Here we use the Global Change Assessment Model (GCAM) to investigate the relative contributions of climate and human systems on water scarcity regionally and globally under a wide range of scenarios. The model accounts for a variety of human activities, including changing demands for water for agriculture, power generation, industry, and public supply. We find that these activities exert a larger influence on water scarcity than climate in 93% of river basins globally. This work highlights the importance of accounting for human activities in hydrologic modeling applications and how they may change under different pathways of how land use and agricultural systems, energy systems, and economies may evolve in the future.

    2013-10-01

    We analyze whether the prediction of the fractal markets hypothesis about a dominance of specific investment horizons during turbulent times holds. To do so, we utilize the continuous wavelet transform analysis and obtained wavelet power spectra which give the crucial information about the variance distribution across scales and its evolution in time. We show that the most turbulent times of the Global Financial Crisis can be very well characterized by the dominance of short investment horizons which is in hand with the assertions of the fractal markets hypothesis.

  4. Liberty, Security and Power: Some Reflections on Transatlantic Relations

    Angela Liberatore

    2009-08-01

    Full Text Available The leitmotiv of the tensions between security and liberty is recurrent in democratic debate – especially in connection with wars, but also in relation to other cases where internal or external threats are seen as requiring the sacrifice of liberty to guarantee survival. Such tension can hardly arise in non-democracies, where liberties are seen as a threat themselves by those in power, while a democracy cannot survive as such without safeguarding liberty – including to criticise and ‘send back home’ those in power. Following the terrorist attacks of 11 September 2001 the issue became especially acute, and heavily reflected on policies in the European Union (EU as well as in the relation between the EU and the USA. The changes taking place in the USA with the election of President Obama and those, admittedly less visible, taking place in the EU – including the election of the new European Parliament and the fate of the Lisbon Treaty – provide an interesting occasion for some reflection on the kind of continuity or change that may be expected in EU-US relations in handling the relations between security and liberty.

  7. Global assessment of onshore wind power resources considering the distance to urban areas

    Silva Herran, Diego; Dai, Hancheng; Fujimori, Shinichiro; Masui, Toshihiko

    2016-01-01

    This study assessed global onshore wind power resources considering the distance to urban areas in terms of transmission losses and costs, and visibility (landscape impact) restrictions. Including this factor decreased the economic potential considerably depending on the level of supply cost considered (at least 37% and 16% for an economic potential below 10 and 14 US cents/kWh, respectively). Its importance compared to other factors was secondary below 15 US cents/kWh. At higher costs it was secondary only to land use, and was more important than economic and technical factors. The impact of this factor was mixed across all regions of the world, given the heterogeneity of wind resources in remote and proximal areas. Regions where available resources decreased the most included the European Union, Japan, Southeast Asia, the Middle East, and Africa. The supply cost chosen to evaluate the economic potential and uncertainties influencing the estimation of distance to the closest urban area are critical for the assessment. Neglecting the restrictions associated with integration into energy systems and social acceptability resulted in an overestimation of global onshore wind resources. These outcomes are fundamental for global climate policies because they help to clarify the limits of wind energy resource availability. - Highlights: • Global onshore wind resources were assessed including the distance to urban areas. • We evaluate the impact of transmission losses and cost, and visibility restrictions. • The distance to urban areas' impact was considerable, depending on the supply cost. • This factor's importance was secondary to economic, land use, and technical factors. • Neglecting this factor resulted in an overestimation of global wind resources.

  8. Power Deals. Mergers and acquisitions activity within the global electricity and gas market. 2008 Annual Review

    2009-01-01

    2008 was the year in which power deal values came down from their record-breaking highs of the two preceding years as the financial crisis and a number of market uncertainties had a negative impact on deal activity. Nonetheless, total deal numbers leapt by 24% as companies concentrated on smaller deals and took advantage of new opportunities that arose in the changed market conditions. Europe was least affected by the downturn in deal values and accounted for over half of all bidder and target power deal value. In contrast, power deals in Australia, which had previously been a main motor of growing M and A activity in the Asia Pacific region, virtually stalled as uncertainty over new carbon emission policies combined with the financial crisis to deter deal flow. In North America, like Europe, big deals were fewer but underlying deal activity was comparable with previous years. This report examines the rationale behind the overall trends and the key individual deals. We also highlight, in a series of deal dialogues throughout the report, some of the critical issues for companies engaging in deal activity within the sector, drawing on our global experience as an adviser to players in major deals throughout the sector in all key electricity and gas utilities markets. Looking to the future, the easing of the financial crisis will be key to deal flow but the near-term outlook looks less robust than the recent past, especially as debt markets will be further constrained by calls from the public financing required to support government bail-out programmes. Set against this, the underlying imperatives of consolidation, supply security and capitalisation remain in place and will create increasing pent-up deal demand. A lower energy price environment will change the metrics for more expensive cleaner power assets, placing an even higher importance on the outcome of global climate talks and the run-up to the December 2009 UN Climate Summit in Copenhagen

    2014-07-01

    We estimate the global risk from the release and atmospheric dispersion of radionuclides from nuclear power plant accidents using the EMAC atmospheric chemistry-general circulation model. We included all nuclear reactors that are currently operational, under construction and planned or proposed. We implemented constant continuous emissions from each location in the model and simulated atmospheric transport and removal via dry and wet deposition processes over 20 years (2010-2030), driven by boundary conditions based on the IPCC A2 future emissions scenario. We present global overall and seasonal risk maps for potential surface layer concentrations and ground deposition of radionuclides, and estimate potential doses to humans from inhalation and ground-deposition exposures to radionuclides. We find that the risk of harmful doses due to inhalation is typically highest in the Northern Hemisphere during boreal winter, due to relatively shallow boundary layer development and limited mixing. Based on the continued operation of the current nuclear power plants, we calculate that the risk of radioactive contamination to the citizens of the USA will remain to be highest worldwide, followed by India and France. By including stations under construction and those that are planned and proposed, our results suggest that the risk will become highest in China, followed by India and the USA.

  11. Energy choices and risk beliefs: is it just global warming and fear of a nuclear power plant accident?

    Greenberg, Michael; Truelove, Heather Barnes

    2011-05-01

    A survey of 3,200 U.S. residents focused on two issues associated with the use of nuclear and coal fuels to produce electrical energy. The first was the association between risk beliefs and preferences for coal and nuclear energy. As expected, concern about nuclear power plant accidents led to decreased support for nuclear power, and those who believed that coal causes global warming preferred less coal use. Yet other risk beliefs about the coal and nuclear energy fuel cycles were stronger or equal correlates of public preferences. The second issue is the existence of what we call acknowledged risk takers, respondents who favored increased reliance on nuclear energy, although also noting that there could be a serious nuclear plant accident, and those who favored greater coal use, despite acknowledging a link to global warming. The pro-nuclear group disproportionately was affluent educated white males, and the pro-coal group was relatively poor less educated African-American and Latino females. Yet both shared four similarities: older age, trust in management, belief that the energy facilities help the local economy, and individualistic personal values. These findings show that there is no single public with regard to energy preferences and risk beliefs. Rather, there are multiple populations with different viewpoints that surely would benefit by hearing a clear and comprehensive national energy life cycle policy from the national government. © 2010 Society for Risk Analysis.

  12. Conflict and diarrheal and related diseases: a global analysis.

    Kerridge, Bradley T; Khan, Maria R; Rehm, Jürgen; Sapkota, Amir

    2013-12-01

    The purpose of this study was to determine the association between deaths owing to terrorism, civil war and one-sided violence from 1994-2000 and disability-adjusted life years (DALYs) attributable to diarrheal and related diseases, schistosomiasis, trachoma and the nematode infections (DSTN diseases) in 2002 among World Health Organization Member States. Deaths resulting from terrorism, civil war and one-sided violence were significantly related to DSTN DALYs across the majority of sex-age subgroups of the populace, after controlling for baseline levels of improved water/sanitation and a variety of economic measures: overall, a 1.0% increase in deaths owing to terrorism and related violence was associated with an increase of 0.16% in DALYs lost to DSTN diseases. Associations were greatest among 0-to-4-year olds. The results of the present study suggest that DSTN disease control efforts should target conflict-affected populations with particular attention to young children who suffer disproportionately from DSTN diseases in these settings. In view of the evidence that terrorism and related violence may influence DSTN DALYs in the longer term, control strategies should move beyond immediate responses to decrease the incidence and severity of DSTN diseases to seek solutions through bolstering health systems infrastructure development among conflict-affected populations.

  13. The rise of smart customers. How consumer power will change the global power and utilities business. What consumers think

    NONE

    2011-08-15

    Smart technology puts unprecedented power in the hands of consumers to manage and control their energy use. In time, this will fundamentally shift the balance of customer relations. It seems the era of a one-way relationship - where a utility delivers energy to domestic consumers, end of story - is over. Most power and utility businesses are currently treating the smart transition as an infrastructure upgrade, focusing chiefly on the technology and on fulfilling regulatory obligations. So far, the customer perspective and need for consumer education have not figured prominently in smart implementation programs. But following customer resistance to implementations in the US and Australia, the sector has been alerted to further challenges. Consumers' newfound power to say 'no' is one that the industry is not used to dealing with. Power and utility businesses must learn from the mistakes made so far. They need customer buy-in before they can exploit the host of new business opportunities that smart technology could provide. To explore the sector's readiness to respond to the present cycle of change, we asked domestic energy consumers how they viewed their relationship with energy providers. We wanted to know if they understood the benefits of smart metering, as well as their appetite for smart energy services.

  14. The Global Precipitation Measurement (GPM) Spacecraft Power System Design and Orbital Performance

    2016-01-01

    The Global Precipitation Measurement (GPM) spacecraft was jointly developed by National Aeronautics and Space Administration (NASA) and Japan Aerospace Exploration Agency (JAXA). It is a Low Earth Orbit (LEO) spacecraft launched on February 27, 2014. The spacecraft is in a circular 400 Km altitude, 65 degrees inclination nadir pointing orbit with a three year basic mission life. The solar array consists of two sun tracking wings with cable wraps. The panels are populated with triple junction cells of nominal 29.5% efficiency. One axis is canted by 52 degrees to provide power to the spacecraft at high beta angles. The power system is a Direct Energy Transfer (DET) system designed to support 1950 Watts orbit average power. The batteries use SONY 18650HC cells and consist of three 8s x 84p batteries operated in parallel as a single battery. The paper describes the power system design details, its performance to date and the lithium ion battery model that was developed for use in the energy balance analysis and is being used to predict the on-orbit health of the battery.

  15. Uniform decrease of alpha-global field power induced by intermittent photic stimulation of healthy subjects

    Rau R.

    2002-01-01

    Full Text Available Nineteen-channel EEGs were recorded from the scalp surface of 30 healthy subjects (16 males and 14 females, mean age: 34 years, SD: 11.7 years at rest and under trains of intermittent photic stimulation (IPS at rates of 5, 10 and 20 Hz. Digitalized data were submitted to spectral analysis with fast fourier transformation providing the basis for the computation of global field power (GFP. For quantification, GFP values in the frequency ranges of 5, 10 and 20 Hz at rest were divided by the corresponding data obtained under IPS. All subjects showed a photic driving effect at each rate of stimulation. GFP data were normally distributed, whereas ratios from photic driving effect data showed no uniform behavior due to high interindividual variability. Suppression of alpha-power after IPS with 10 Hz was observed in about 70% of the volunteers. In contrast, ratios of alpha-power were unequivocal in all subjects: IPS at 20 Hz always led to a suppression of alpha-power. Dividing alpha-GFP with 20-Hz IPS by alpha-GFP at rest (R = alpha-GFP IPS/alpha-GFPrest thus resulted in ratios lower than 1. We conclude that ratios from GFP data with 20-Hz IPS may provide a suitable paradigm for further investigations.

  16. The Ghost Is the Machine: How Can We Visibilize the Unseen Norms and Power of Global Health? Comment on "Navigating Between Stealth Advocacy and Unconscious Dogmatism: The Challenge of Researching the Norms, Politics and Power of Global Health".

    Forman, Lisa

    2015-12-03

    In his recent commentary, Gorik Ooms argues that "denying that researchers, like all humans, have personal opinions ... drives researchers' personal opinion underground, turning global health science into unconscious dogmatism or stealth advocacy, avoiding the crucial debate about the politics and underlying normative premises of global health." These 'unconscious' dimensions of global health are as Ooms and others suggest, rooted in its unacknowledged normative, political and power aspects. But why would these aspects be either unconscious or unacknowledged? In this commentary, I argue that the 'unconscious' and 'unacknowledged' nature of the norms, politics and power that drive global health is a direct byproduct of the processes through which power operates, and a primary mechanism by which power sustains and reinforces itself. To identify what is unconscious and unacknowledged requires more than broadening the disciplinary base of global health research to those social sciences with deep traditions of thought in the domains of power, politics and norms, albeit that doing so is a fundamental first step. I argue that it also requires individual and institutional commitments to adopt reflexive, humble and above all else, equitable practices within global health research. © 2016 by Kerman University of Medical Sciences.

  17. Power and momentum relations in rotating magnetic field current drive

    Hugrass, W N [Flinders Univ. of South Australia, Bedford Park. School of Physical Sciences

    1984-01-01

    The use of rotating magnetic fields (RMF) to drive steady currents in plasmas involves a transfer of energy and angular momentum from the radio frequency source feeding the rotating field coils to the plasma. The power-torque relationships in RMF systems are discussed and the analogy between RMF current drive and the polyphase induction motor is explained. The general relationship between the energy and angular momentum transfer is utilized to calculate the efficiency of the RMF plasma current drive. It is found that relatively high efficiencies can be achieved in RMF current drive because of the low phase velocity and small slip between the rotating field and the electron fluid.

    Hennig, R. J.; Friedrich, J.; Malaguzzi Valeri, L.; McCormick, C.; Lebling, K.; Kressig, A.

    2016-12-01

    The Power Watch project will offer open data on the global electricity sector starting with power plants and their impacts on climate and water systems; it will also offer visualizations and decision making tools. Power Watch will create the first comprehensive, open database of power plants globally by compiling data from national governments, public and private utilities, transmission grid operators, and other data providers to create a core dataset that has information on over 80% of global installed capacity for electrical generation. Power plant data will at a minimum include latitude and longitude, capacity, fuel type, emissions, water usage, ownership, and annual generation. By providing data that is both comprehensive, as well as making it publically available, this project will support decision making and analysis by actors across the economy and in the research community. The Power Watch research effort focuses on creating a global standard for power plant information, gathering and standardizing data from multiple sources, matching information from multiple sources on a plant level, testing cross-validation approaches (regional statistics, crowdsourcing, satellite data, and others) and developing estimation methodologies for generation, emissions, and water usage. When not available from official reports, emissions, annual generation, and water usage will be estimated. Water use estimates of power plants will be based on capacity, fuel type and satellite imagery to identify cooling types. This analysis is being piloted in several states in India and will then be scaled up to a global level. Other planned applications of of the Power Watch data include improving understanding of energy access, air pollution, emissions estimation, stranded asset analysis, life cycle analysis, tracking of proposed plants and curtailment analysis.

  3. Electric power and the global economy: Advances in database construction and sector representation

    Peters, Jeffrey C.

    The electricity sector plays a crucial role in the global economy. The sector is a major consumer of fossil fuel resources, producer of greenhouse gas emissions, and an important indicator and correlate of economic development. As such, the sector is a primary target for policy-makers seeking to address these issues. The sector is also experiencing rapid technological change in generation (e.g. renewables), primary inputs (e.g. horizontal drilling and hydraulic fracturing), and end-use efficiency. This dissertation seeks to further our understanding of the role of the electricity sector as part of the dynamic global energy-economy, which requires significant research advances in both database construction and modeling techniques. Chapter 2 identifies useful engineering-level data and presents a novel matrix balancing method for integrating these data in global economic databases. Chapter 3 demonstrates the relationship between matrix balancing method and modeling results, and Chapter 4 presents the full construction methodology for GTAP-Power, the foremost, publicly-available global computable general equilibrium database. Chapter 5 presents an electricity-detailed computational equilibrium model that explicitly and endogenously captures capacity utilization, capacity expansion, and their interdependency - important aspects of technological substitution in the electricity sector. The individual, but interrelated, research contributions to database construction and electricity modeling in computational equilibrium are placed in the context of analyzing the US EPA Clean Power Plan (CPP) CO 2 target of 32 percent reduction of CO2 emissions in the US electricity sector from a 2005 baseline by 2030. Assuming current fuel prices, the model predicts an almost 28 percent CO2 reduction without further policy intervention. Next, a carbon tax and investment subsidies for renewable technologies to meet the CPP full targets are imposed and compared (Chapter 6). The carbon tax

  4. Reduced order models, inertial manifolds, and global bifurcations: searching instability boundaries in nuclear power systems

    Suarez Antola, R.

    2011-01-01

    One of the goals of nuclear power systems design and operation is to restrict the possible states of certain critical subsystems, during steady operation and during transients, to remain inside a certain bounded set of admissible states and state variations. Also, during transients, certain restrictions must be imposed on the time scale of evolution of the critical subsystem's state. A classification of the different solution types concerning their relation with the operational safety of the power plant is done by distributing the different solution types in relation with the exclusion region of the power-flow map. In the framework of an analytic or numerical modeling process of a boiling water reactor (BWR) power plant, this could imply first to find an suitable approximation to the solution manifold of the differential equations describing the stability behavior of this nonlinear system, and then a classification of the different solution types concerning their relation with the operational safety of the power plant, by distributing the different solution types in relation with the exclusion region of the power-flow map. Inertial manifold theory gives a foundation for the construction and use of reduced order models (ROM's) of reactor dynamics to discover and characterize meaningful bifurcations that may pass unnoticed during digital simulations done with full scale computer codes of the nuclear power plant. The March-Leuba's BWR ROM is used to exemplify the analytical approach developed here. The equation for excess void reactivity of this ROM is generalized. A nonlinear integral-differential equation in the logarithmic power is derived, including the generalized thermal-hydraulics feedback on the reactivity. Introducing a Krilov- Bogoliubov-Mitropolsky (KBM) ansatz with both amplitude and phase being slowly varying functions of time relative to the center period of oscillation, a coupled set of nonlinear ordinary differential equations for amplitude and phase

    2017-01-01

    Malaysia had considered nuclear energy as an option for future electricity generation during the 9th Malaysia Development Plan. Since 2009, Malaysia had implemented a number of important preparatory steps towards this goal, including the establishment of Nuclear Power Corporation of Malaysia (MNPC) as first Nuclear Energy Programme Implementing Organization (NEPIO) in Malaysia. In light of the establishment of MNPC, the National Nuclear Policy was formulated in 2010 and a new comprehensive nuclear law to replace the existing Atomic Energy Licensing Act (Act 304) is currently in the pipeline. Internationally, public acceptance is generally used to gauge the acceptance of nuclear energy by the public whenever a government decides to engage in nuclear energy. A public survey was conducted in between 14 March 2016 to 10 May 2016 focusing on the Malaysian public acceptance and perception towards the implementation of nuclear energy in Malaysia. The methodology of this research was aim on finding an overview of the general knowledge, public-relation recommendation, perception and acceptance of Malaysian towards the nuclear power development program. The combination of information gathered from this study can be interpreted as an indication of the complexity surrounding the development of nuclear energy and its relationship with the unique background of Malaysian demography. This paper will focus mainly on energy-related section in the survey in comparison with nuclear energy.

    Full Text Available The papers included in this collection are part of concerted project to develop a political economy of law in the contemporary global system. Over the past two decades, scholars have noted the expanding role of law, legal institutions, and legal agents that have been part of the process of “globalization,” and have employed a number of frameworks to make sense of this process of legalization. A central theme of our project is that none of these frameworks has provided an adequate political economic analysis of the creation, diffusion, and use of law, and we present an alternative approach to advance the understanding of the turn to law across the many dimensions and sectors of the global system. The papers advance the analysis behind this approach and explore the various ways in which law matters in a variety of areas, including global finance, corporate governance, copyright, diplomacy, and the provision of security. Their goal is to advance our understanding of how law intersects with the mobilization of power in the construction of the contemporary political economy.

En las últimas dos décadas, los expertos han señalado el creciente papel de la ley, las instituciones legales, y los agentes judiciales que han sido parte del proceso de "globalización", y han empleado una serie de marcos para dar sentido a este proceso de legalización. Un tema central de nuestro proyecto es que ninguno de estos marcos ha proporcionado un adecuado análisis económico político de la creación, difusión y uso de la ley, y se presenta un enfoque alternativo para avanzar en la comprensión de la vuelta a la ley a través de las muchas dimensiones y sectores del sistema global.

  12. Power spectral density and scaling exponent of high frequency global solar radiation sequences

    Calif, Rudy; Schmitt, François G.; Huang, Yongxiang

    2013-04-01

    The part of the solar power production from photovlotaïcs systems is constantly increasing in the electric grids. Solar energy converter devices such as photovoltaic cells are very sensitive to instantaneous solar radiation fluctuations. Thus rapid variation of solar radiation due to changes in the local meteorological condition can induce large amplitude fluctuations of the produced electrical power and reduce the overall efficiency of the system. When large amount of photovoltaic electricity is send into a weak or small electricity network such as island network, the electric grid security can be in jeopardy due to these power fluctuations. The integration of this energy in the electrical network remains a major challenge, due to the high variability of solar radiation in time and space. To palliate these difficulties, it is essential to identify the characteristic of these fluctuations in order to anticipate the eventuality of power shortage or power surge. The objective of this study is to present an approach based on Empirical Mode Decomposition (EMD) and Hilbert-Huang Transform (HHT) to highlight the scaling properties of global solar irradiance data G(t). The scale of invariance is detected on this dataset using the Empirical Mode Decomposition in association with arbitrary-order Hilbert spectral analysis, a generalization of (HHT) or Hilbert Spectral Analysis (HSA). The first step is the EMD, consists in decomposing the normalized global solar radiation data G'(t) into several Intrinsic Mode Functions (IMF) Ci(t) without giving an a priori basis. Consequently, the normalized original solar radiation sequence G'(t) can be written as a sum of Ci(t) with a residual rn. From all IMF modes, a joint PDF P(f,A) of locally and instantaneous frequency f and amplitude A, is estimated. To characterize the scaling behavior in amplitude-frequency space, an arbitrary-order Hilbert marginal spectrum is defined to: Iq(f) = 0 P (f,A)A dA (1) with q × 0 In case of scale

  13. A fault diagnosis system for PV power station based on global partitioned gradually approximation method

    Wang, S.; Zhang, X. N.; Gao, D. D.; Liu, H. X.; Ye, J.; Li, L. R.

    2016-08-01

    As the solar photovoltaic (PV) power is applied extensively, more attentions are paid to the maintenance and fault diagnosis of PV power plants. Based on analysis of the structure of PV power station, the global partitioned gradually approximation method is proposed as a fault diagnosis algorithm to determine and locate the fault of PV panels. The PV array is divided into 16x16 blocks and numbered. On the basis of modularly processing of the PV array, the current values of each block are analyzed. The mean current value of each block is used for calculating the fault weigh factor. The fault threshold is defined to determine the fault, and the shade is considered to reduce the probability of misjudgments. A fault diagnosis system is designed and implemented with LabVIEW. And it has some functions including the data realtime display, online check, statistics, real-time prediction and fault diagnosis. Through the data from PV plants, the algorithm is verified. The results show that the fault diagnosis results are accurate, and the system works well. The validity and the possibility of the system are verified by the results as well. The developed system will be benefit for the maintenance and management of large scale PV array.

  14. Investigation of potential fire-related damage to safety-related equipment in nuclear power plants

    1985-11-01

    Based on a review of vendor information, fire damage reports, equipment qualification and hydrogen burn test results, and material properties, thirty-three types of equipment found in nuclear power plants were ranked in terms of their potential sensitivity to fire environments. The ranking considered both the functional requirements and damage proneness of each component. A further review of the seven top-ranked components was performed, considering the relative prevalence and potential safety significance of each. From this, relays and hand switches dominate as first choices for fire damage testing with logic equipment, power supplies, transmitters, and motor control centers as future candidates

    International development programmes, including global health interventions, have the capacity to make important implicit and explicit benefits to diplomatic and international relations outcomes. Conversely, in the absence of awareness of these implications, such programmes may generate associated threats. Due to heightened international tensions in conflict and post-conflict settings, greater attention to diplomatic outcomes may therefore be necessary. We examine related 'collateral' effects of Global Fund-supported tuberculosis programmes in Iraq. During site visits to Iraq conducted during 2012 and 2013 on behalf of the Global Fund to Fight AIDS, Tuberculosis and Malaria, on-site service delivery evaluations, unstructured interviews with clinical and operational staff, and programme documentary review of Global Fund-supported tuberculosis treatment and care programmes were conducted. During this process, a range of possible external or collateral international relations and diplomatic effects of global health programmes were assessed according to predetermined criteria. A range of positive diplomatic and international relations effects of Global Fund-supported programmes were observed in the Iraq setting. These included (1) geo-strategic accessibility and coverage; (2) provisions for programme sustainability and alignment; (3) contributions to nation-building and peace-keeping initiatives; (4) consistent observation of social, cultural and religious norms in intervention selection; and (5) selection of the most effective and cost-effective tuberculosis treatment and care interventions. Investments in global health programmes have valuable diplomatic, as well as health-related, outcomes, associated with their potential to prevent, mitigate or reverse international tension and hostility in conflict and post-conflict settings, provided that they adhere to appropriate criteria. The associated international presence in such regions may also contribute to peace

    Full Text Available This article addresses the analysis of power relations within the operation of social welfare policy, based on a case study conducted in Londrina, Paraná. Our analysis adopts a relational perspective on the confi guration of power among the beneficiaries of the policy and the social workers responsible for implementing state actions to fi ght poverty. Basically what we found were areas of dissonance between conceptions and perceptions of users and social workers, so that an unreadable universe is created for users on social welfare and, thus, possible ways to consolidate the transfer of income are blocked as a right to citizenship. We focus on actions related to the transfer of income because of its relevance to the Brazilian social welfare today.

  17. Globally Stable Microresonator Turing Pattern Formation for Coherent High-Power THz Radiation On-Chip

    Huang, Shu-Wei; Yang, Jinghui; Yang, Shang-Hua; Yu, Mingbin; Kwong, Dim-Lee; Zelevinsky, T.; Jarrahi, Mona; Wong, Chee Wei

    2017-10-01

    In nonlinear microresonators driven by continuous-wave (cw) lasers, Turing patterns have been studied in the formalism of the Lugiato-Lefever equation with emphasis on their high coherence and exceptional robustness against perturbations. Destabilization of Turing patterns and the transition to spatiotemporal chaos, however, limit the available energy carried in the Turing rolls and prevent further harvest of their high coherence and robustness to noise. Here, we report a novel scheme to circumvent such destabilization, by incorporating the effect of local mode hybridizations, and we attain globally stable Turing pattern formation in chip-scale nonlinear oscillators with significantly enlarged parameter space, achieving a record-high power-conversion efficiency of 45% and an elevated peak-to-valley contrast of 100. The stationary Turing pattern is discretely tunable across 430 GHz on a THz carrier, with a fractional frequency sideband nonuniformity measured at 7.3 ×10-14 . We demonstrate the simultaneous microwave and optical coherence of the Turing rolls at different evolution stages through ultrafast optical correlation techniques. The free-running Turing-roll coherence, 9 kHz in 200 ms and 160 kHz in 20 minutes, is transferred onto a plasmonic photomixer for one of the highest-power THz coherent generations at room temperature, with 1.1% optical-to-THz power conversion. Its long-term stability can be further improved by more than 2 orders of magnitude, reaching an Allan deviation of 6 ×10-10 at 100 s, with a simple computer-aided slow feedback control. The demonstrated on-chip coherent high-power Turing-THz system is promising to find applications in astrophysics, medical imaging, and wireless communications.

  18. Unified force and its relation with global warming crave for hydrogen energy and promote fuel cell technology

    Krishnan, K.J.; Kalam, A.

    2011-01-01

    Global warming is presently a tremendous public interest and has become a threat to every individual. Huge quantities of CO/sub 2/ are emitted to the atmosphere by burning of fossil fuels to produce electricity in power plants and burning of gasoline in aeroplanes and vehicles. Enormous amount of greenhouse gasses are sent into the air when garbage is burnt in landfills. Cutting down of trees and other plants which collect CO/sub 2/ a greenhouse gas which is inhaled and which gives back oxygen which is exhaled makes global warming worse. 'Self-Compressive Surrounding Pressure Force' which is also known as Unified Force is also related with global warming which is proportional to increase of H/sub 2/O level in sea and causes floods, storms, droughts and severe impacts to the environment and society. In order to better understand global warming and its relation with Unified Force, this paper discusses the cause and effect system on the amount of greenhouse gases emitted to the atmosphere from the burning of fossil fuels and also the other green house gases like CH/sub 4/, water vapour, NOx etc. and emphasis its importance to focus on crave for Hydrogen Energy and to promote Fuel Cell technology to keep the earth green and safer from the impacts of global warming. The benefit of switching from fossil fuels to Hydrogen Energy and Fuel Cell technology reduces the impact of global warming, elimination of pollution caused by fossil fuels and greenhouse gases, economic dependence and distributed production.

    2015-07-01

    Full Text Available This paper aims to present an improved version of a typical particle swarm optimization (PSO algorithm, such that the global maximum power point (MPP on a P-V characteristic curve with multiple peaks can be located in an efficient and precise manner for a photovoltaic module array. A series of instrumental measurements are conducted on variously configured arrays built with SANYO HIP2717 PV modules, either unshaded, partially shaded, or malfunctioning, as the building blocks. There appear two, triple and quadruple peaks on the corresponding P-V characteristic curves. Subsequently, the tracking performance comparisons, made by some practical experiments, indicate the superiority of this improved MPP tracking algorithm over the typical one.

    2007-01-01

    The global warming effect due to ?greenhouse gases? is a hot topic discussed by world climate scientists today. This effect causes sea levels to rise, countries experiencing extreme weather conditions, violent storms and long dry spells. In centuries to come, these catastrophic effects can cause the spread of diseases and destroy food production and human habitat. Over one-third of the greenhouse gases come from the burning of fossil fuel to generate electricity. Nuclear power plants do not generate these gases. This paper presents the results obtained from a case study using MESSAGE, an analytical tool developed by the IAEA, which was used to evaluate Malaysia future energy requirements and strategies in addressing climate change issues.

  1. Consistency relation in power law G-inflation

    Unnikrishnan, Sanil; Shankaranarayanan, S.

    2014-01-01

    In the standard inflationary scenario based on a minimally coupled scalar field, canonical or non-canonical, the subluminal propagation of speed of scalar perturbations ensures the following consistency relation: r ≤ −8n T , where r is the tensor-to-scalar-ratio and n T is the spectral index for tensor perturbations. However, recently, it has been demonstrated that this consistency relation could be violated in Galilean inflation models even in the absence of superluminal propagation of scalar perturbations. It is therefore interesting to investigate whether the subluminal propagation of scalar field perturbations impose any bound on the ratio r/|n T | in G-inflation models. In this paper, we derive the consistency relation for a class of G-inflation models that lead to power law inflation. Within these class of models, it turns out that one can have r > −8n T or r ≤ −8n T depending on the model parameters. However, the subluminal propagation of speed of scalar field perturbations, as required by causality, restricts r ≤ −(32/3) n T

    2014-06-01

    Full Text Available Turkey's role as a regional power has increased since Justice and Development Party (AKP came to power. AKP leadership not only aspired to become a regional power but also a global player. Turkey has, therefore, assumed different roles: the "natural leader" of the region; a historical "big brother;" and the "protector" of the Muslim minorities. Turkey has also assumed a "mediator" and a "facilitator" role by trying to negotiate a deal with an emerging power such as Brazil in order to attempt to resolve the controversial Iranian nuclear issue. By making use of recent developments, Turkey tried to solidify its long desired role as a "rising power" by increasing its influence in its neighborhood and engaging with other emerging powers. The concept "regional power" is a context-based notion. In other words, the location and geography are contesting and disputed approaches. Notwithstanding the fact that concepts such as "region" and "power" are social constructed reality, this paper analyzes the notion of 'regional power' as a subcategory of 'power'. In this context, this paper will make use of Stefan Schim's criteria while analyzing Turkey's power capacity in the region. Schim posits that the "regional power" needs to have a "role definition," and it should possess material power (hard power. It should also have economic as well as diplomatic and organizational capacity. Its power whether it is 'soft power' (attraction of ones idea's and or the ability to set the political agenda in a way that shapes the preferences of other actors or 'hard power' (material power that can be measured-economic and military power needs to be acknowledged by other actors in the region. It should also be accepted by great powers and emerging powers that are determinant in the international system. dditionally, the regional power (and/ or global power needs to have leverage, thus its power projection needs to yield results.

    2000-02-01

    The article discusses effects and results of globalization for nuclear power and other options of electricity generation. According to the present state of knowledge, it will not be possible to meet the growing worldwide energy requirement with fossil and renewable energy sources only - also because of the CO{sub 2} problem. Consequently, nuclear power will remain an important alternative. On an international scale, this applies in particular to large countries, such as China and India, as large national economies particularly benefit from the economies of scale offered by nuclear power. This could well make Chinese nuclear technology a product for the world market. Thinking along these lines has not really gained ground in Germany, as nuclear power, being a technology requiring considerably capital outlay, is considered unsuitable for southern countries. It is an illusion to believe that Germany's opting out of the use of nuclear power could be a model to others. Instead, we are faced by the ethical question of how we can help to minimize the accident risks of nuclear facilities worldwide. We can do so only by maintaining the use of nuclear power and exporting our level of safety, for the risks will not become any smaller merely as a result of our opting out. (orig.)

  7. The 'International' and the 'Global' as Complementary Power Strategies within Corporate Roman Catholicism

    Kenneth Houston

    2010-09-01

    Full Text Available The putative resurgence of religious belief and its reinvigorated socio-political importance – or at least prominence – has prompted critical reflection on religion, broadly defined, as a new force in politics. This paper examines the ‘global’ and ‘international’ role of Roman Catholicism. Roman Catholicism has manifested itself as an actor on the international stage and as a trans-national and global ‘community’. Frequently the conceptual dividing line between these is ambiguous. Vatican City and the Holy See have both been accorded international status, the former since the conclusion of the Lateran Treaty by Italy’s fascist leader, Benito Mussolini, in 1929, the latter since the mid nineteenth century following the absorption of the Papal States into the newly unified Italian Republic. The Holy See also enjoys a special status position within the United Nations system as a non-member observer state. Following revelations of clerical child abuse the Holy See was put on the defensive in several national contexts in a public controversy that resonated much more widely. This trans-nationally organised religion has mobilised both nationally and internationally to defend its institutional interests. Through an examination of empirical instances the study sidesteps the question of whether religions are ‘global’ or ‘international’ phenomena, and draws attention to the distinct power modalities operative at the level of both international politics and in transnational or global organisation.

  8. Nuclear power and global warming: a first cost-benefit calculation

    Hope, C.

    1994-01-01

    This paper investigates the costs and benefits of a modest nuclear power programme in the European Union to combat the threat of global warming. The nuclear programme is found to bring a double benefit. The first and more obvious benefit is that the economic impacts of global warming are reduced. The second benefit is counter-intuitive; most people would expect it to be a cost. It comes from the stimulus to the economy from the construction of the nuclear plant, which, with the recycling of carbon tax revenues, offsets its construction and operating costs, and may even cause consumers' expenditure to rise. Calculations in this paper show that over the period to 2100 the mean net present value of the first benefit is 6 billion European Currency Units (ECU; 1 ECU is about Dollars 1), while the second benefit has a mean net present value of 159 billion ECU. However both benefits, particularly the second, are still very uncertain, to the extent that even their sign is not yet definitely established. (author)

  9. "Power quality system," a new system of quality management for globalization: towards innovation and competitive advantages.

    Abdul-Rahman, H; Berawi, M A

    Knowledge Management (KM) addresses the critical issues of organizational adoption, survival and competence in the face of an increasingly changing environment. KM embodies organizational processes that seek a synergistic combination of the data and information processing capabilities of information and communication technologies (ICT), and the creative and innovative capacity of human beings to improve ICT In that role, knowledge management will improve quality management and avoid or minimize losses and weakness that usually come from poor performance as well as increase the competitive level of the company and its ability to survive in the global marketplace. To achieve quality, all parties including the clients, company consultants, contractors, entrepreneurs, suppliers, and the governing bodies (i.e., all involved stake-holders) need to collaborate and commit to achieving quality. The design based organizations in major business and construction companies have to be quality driven to support healthy growth in today's competitive market. In the march towards vision 2020 and globalization (i.e., the one world community) of many companies, their design based organizations need to have superior quality management and knowledge management to anticipate changes. The implementation of a quality system such as the ISO 9000 Standards, Total Quality Management, or Quality Function Deployment (QFD) focuses the company's resources towards achieving faster and better results in the global market with less cost. To anticipate the needs of the marketplace and clients as the world and technology change, a new system, which we call Power Quality System (PQS), has been designed. PQS is a combination of information and communication technologies (ICT) and the creative and innovative capacity of human beings to meet the challenges of the new world business and to develop high quality products.

    uses of electricity and fuels currently covered by fossil fuels. This is a global replacement load of about 9000 gigawatts. Green theorists are divided on this issue. Some claim that ground based solar, wind, and other renewable sources will supply all the energy we need, ignoring economic costs that severely limit their use. Others would (unrealistically) require the developed countries to reduce their energy consumption per capita to a level closer to that of the developing world, thereby admitting the limitations of the "appropriate" systems they espouse. Both sides in the past have rejected as "non-appropriate" and/or "dangerous" all the chemically clean energy sources of high capacity that have been previously proposed, such as safer nuclear fission, fusion power, and space solar power. If ground based "appropriate" energy sources are not sufficient, the economic and social effects of sudden forced curtailments of fossil energy use could be drastic. This paper supports the thesis that Space Solar Power does have the potential to provide such a clean, abundant, and economical energy source. It will cover both the limitations and promise of ground based energy sources, including the difficulties of using intermittent energy sources. It will discuss whether specified levels of energy cost increases would be damaging to the world economy and whether economical ground based sources alone would have sufficient capacity. It will show how the one major problem of launch costs, (currently preventing economical implementation of Space Solar Power), has a number of quite reasonable solutions. Finally, it will consider whether Space Solar Power, along with the other major space goals of Science &Exploration, Mars Colonization, Non- terrestrial Materials Recovery and Space Tourism, could be another space "killer app" which, by creating a high demand for launch services, could force large reductions in launch costs.

  11. Structural Power and International Relations Analysis: "Fill your basket, get your preferences"

    In this article, we will address current deficits of the study of power in IR by introducing a new concept of structural power. After briefly presenting existing concepts of relational power, of structural power as well as of conceptualizing power as the possession of resources (power-as-resources), we will introduce our concept of structural power as an approach suitable for bridging the gap between existing concepts (by strongly focusing on the importance of the structural level). We will s...

    and creativity suggests that when managers give people the opportunity to gain power and explicate that there is reason to be more creative, people will show a boost in creative behaviour. Moreover, this process works best in unstable power hierarchies, which implies that power is treated as a negotiable....... It is thus a central point that power is not necessarily something that breaks down and represses. On the contrary, an explicit focus on the dynamics of power in relation to creativity can be productive for the organisation. Our main focus is to elaborate the implications of this for practice and theory...

  14. A power law global error model for the identification of differentially expressed genes in microarray data

    Granucci Francesca

    2004-12-01

    Full Text Available Abstract Background High-density oligonucleotide microarray technology enables the discovery of genes that are transcriptionally modulated in different biological samples due to physiology, disease or intervention. Methods for the identification of these so-called "differentially expressed genes" (DEG would largely benefit from a deeper knowledge of the intrinsic measurement variability. Though it is clear that variance of repeated measures is highly dependent on the average expression level of a given gene, there is still a lack of consensus on how signal reproducibility is linked to signal intensity. The aim of this study was to empirically model the variance versus mean dependence in microarray data to improve the performance of existing methods for identifying DEG. Results In the present work we used data generated by our lab as well as publicly available data sets to show that dispersion of repeated measures depends on location of the measures themselves following a power law. This enables us to construct a power law global error model (PLGEM that is applicable to various Affymetrix GeneChip data sets. A new DEG identification method is therefore proposed, consisting of a statistic designed to make explicit use of model-derived measurement spread estimates and a resampling-based hypothesis testing algorithm. Conclusions The new method provides a control of the false positive rate, a good sensitivity vs. specificity trade-off and consistent results with varying number of replicates and even using single samples.

  15. Redefining the Indirect Approach, Defining Special Operations Forces (SOF Power, and the Global Networking of SOF

    Scott Morrison

    2014-07-01

    Full Text Available The current Defense Strategy assigns Special Operations Forces (SOF to play a central role in countering terrorism, weapons of mass destruction, and irregular warfare. However, there has been little published that defines the role of Special Operations alongside air, land, and sea domains. The U.S. Special Operations Community struggles to define its own theoretical concepts such as direct approach and indirect approach. The U.S. SOF circles typically define direct approach with direct action and the indirect approach with foreign internal defense or security force assistance. Military theorist Liddell Hart viewed the indirect approach as a method to orient upon, target, and upset an adversary’s equilibrium in order to plan for and direct decisive blows. Today, the SOF indirect approach is arguable more applicable due to the prevalence of non-state threats and internal conflicts. Following Hart’s definition, precision raids are among the integral components of a broader application of the indirect approach. The approach also networks U.S. government power as a force when used in concert with allies and local partners. Global networking along with balanced precision raids will exponentially increase the utility of SOF power and position it to appropriately complement all domains to tackle 21st century challenges.

  16. Local and global particle and power balance in large area capacitive discharges

    Cho, Suwon; Lieberman, M A

    2003-01-01

    Large area radio frequency (rf) capacitive discharges have attracted recent interest for materials etching and deposition on large area substrates. A distinguishing feature is that the radial distribution of the absorbed rf power in these discharges depends on the rf voltage across the plates, independent of the radial variation of the plasma density n(r). A reduced set of steady-state fluid equations has been used to investigate the radial variation of n and electron temperature T e . The derived equations are shown to be invariant with respect to pL and pR, where p is the pressure, L is the plate separation and R is the discharge radius, and can be further reduced to the equations of the usual global balance model when R ε , the energy relaxation length. In this limit, the ionization frequency and T e are essentially independent of radius and n can be approximately described by the usual radial profile of a zeroth-order Bessel function. When R≥λ ε , n and T e are predominantly determined by local particle and power balance, and the n and T e radial profiles are flat over most of the volume except near the radial boundary, where n falls and T e rises to account for the increased losses at the boundary. The scale length of the edge density variation in the local balance regime is shown to be proportional to the energy relaxation length

  17. A Dynamic Approach to the Analysis of Soft Power in International Relations

    Chi Zhang

    2013-12-01

    Full Text Available This article discusses soft power in international relations and the soft power of China’s foreign policy in recent years. After presenting a critique of the soft power theory developed by Joseph S. Nye, the paper provides an alternative interpretation of soft power. The author proposes a dynamic analysis of soft power in international relations, and argues that whether a power resource is soft or hard depends on the perceptions and feelings of various actors in specific situations. Due to the varying degrees of acceptance, power can be divided into hard power, soft power and bargaining power. An analysis should look at the soft or hard effectiveness of a power resource from three perspectives–horizontally, vertically and relatively. Recently, the soft power of China’s foreign policy and international behavior has mainly been manifested in multilateralism, economic diplomacy and a good-neighborly policy.

    The global geothermal electricity market has significantly grown over the last decade and is expected to reach a total installed capacity of 18.4 GWe in 2021 (GEA, 2016). Currently, geothermal project developers customize the size of the power plant to fit the resource being developed. In particular, the turbine is designed and sized to optimize efficiency and resource utilization for electricity production; most often, other power plant components are then chosen to complement the turbine design. These custom turbine designs demand one-off manufacturing processes, which result in higher manufacturing setup costs, longer lead-times, and higher capital costs overall in comparison to larger-volume line manufacturing processes. In contrast, turbines produced in standard increments, manufactured in larger volumes, could result in lower costs per turbine. This study focuses on analysis of the global supply chain and manufacturing costs for Organic Rankine Cycle (ORC) turboexpanders and steam turbines used in geothermal power plants. In this study, we developed a manufacturing cost model to identify requirements for equipment, facilities, raw materials, and labor. We analyzed three different cases 1) 1 MWe geothermal ORC turboexpander 2) 5 MWe ORC turboexpander and 3) 20 MWe geothermal steam turbine, and calculated the cost of manufacturing the major components, such as the impellers/blades, shaft/rotor, nozzles, inlet guide lanes, disks, and casings. Then we used discounted cash flow (DCF) analysis to calculate the minimum sustainable price (MSP). MSP is the minimum price that a company must sell its product for in order to pay back the capital and operating expenses during the plant lifetime (CEMAC, 2017). The results showed that MSP could highly vary between 893 dollar/kW and 30 dollar/kW based on turbine size, standardization and volume of manufacturing. The analysis also showed that the economy of scale applies both to the size of the turbine and the number

    , the client exercised near complete control, with developers unwittingly playing a cooperative but submissive role. Our study makes two principal contributions. First, we combine Hardy’s (1996) multi-dimensional power framework and the principles of Pickering’s (1995) version of disciplinary agency to propose...... why the developer was compliant in this scenario of power inequality. Second, we examine how a development methodology helped convey symbolic and disciplinary power. By doing so we gain rich insight into how meaning power, and the power of the system institutionalised within the methodology, can...... constrain the actions of developers....

    One of the goals of nuclear power systems design and operation is to restrict the possible states of certain critical subsystems to remain inside a certain bounded set of admissible states and state variations. In the framework of an analytic or numerical modeling process of a BWR power plant, this could imply first to find a suitable approximation to the solution manifold of the differential equations describing the stability behavior, and then a classification of the different solution types concerning their relation with the operational safety of the power plant. Inertial manifold theory gives a foundation for the construction and use of reduced order models (ROM's) of reactor dynamics to discover and characterize meaningful bifurcations that may pass unnoticed during digital simulations done with full scale computer codes of the nuclear power plant. The March-Leuba's BWR ROM is generalized and used to exemplify the analytical approach developed here. A nonlinear integral-differential equation in the logarithmic power is derived. Introducing a KBM Ansatz, a coupled set of two nonlinear ordinary differential equations is obtained. Analytical formulae are derived for the frequency of oscillation and the parameters that determine the stability of the steady states, including sub- and supercritical PAH bifurcations. A Bautin's bifurcation scenario seems possible on the power-flow plane: near the boundary of stability, a region where stable steady states are surrounded by unstable limit cycles surrounded at their turn by stable limit cycles. The analytical results are compared with recent digital simulations and applications of semi-analytical bifurcation theory done with reduced order models of BWR. (author)

    Abstract: Global health research is essentially a normative undertaking: we use it to propose policies that ought to be implemented. To arrive at a normative conclusion in a logical way requires at least one normative premise, one that cannot be derived from empirical evidence alone. But there is no widely accepted normative premise for global health, and the actors with the power to set policies may use a different normative premise than the scholars that propose policies - which may explain...

  4. Issues related to gas use by European power utilities

    Jonchere, J.P.

    1992-01-01

    Gas-fired combined cycle frequently appears as a least-cost option for newly built power plants. Moreover, this option also brings obvious environmental benefits. But, power utilities, facing unavoidable long term uncertainties about electricity demand are not at ease with long term commitments such a a take-or-pay formula or a price indexation not reflecting the market place in the power generation industry. Due to the flexibilities in the management of existing power plants (deferred closures, etc...) or even on the demand side (load shifting, peak clipping, etc...), early decision making is not compulsory. Therefore, a gas breakthrough in the power sector interfuel competition will require a mutual understanding of constraints and flexibilities faced by partners: gas sellers and power utilities. A fair rent sharing between them would certainly be a prerequisite to a large but possibly temporary access of natural gas to the European power sector. 4 refs., 1 fig., 2 tabs

  5. Attentional selection of relative SF mediates global versus local processing: evidence from EEG.

    Flevaris, Anastasia V; Bentin, Shlomo; Robertson, Lynn C

    2011-06-13

    Previous research on functional hemispheric differences in visual processing has associated global perception with low spatial frequency (LSF) processing biases of the right hemisphere (RH) and local perception with high spatial frequency (HSF) processing biases of the left hemisphere (LH). The Double Filtering by Frequency (DFF) theory expanded this hypothesis by proposing that visual attention selects and is directed to relatively LSFs by the RH and relatively HSFs by the LH, suggesting a direct causal relationship between SF selection and global versus local perception. We tested this idea in the current experiment by comparing activity in the EEG recorded at posterior right and posterior left hemisphere sites while participants' attention was directed to global or local levels of processing after selection of relatively LSFs versus HSFs in a previous stimulus. Hemispheric asymmetry in the alpha band (8-12 Hz) during preparation for global versus local processing was modulated by the selected SF. In contrast, preparatory activity associated with selection of SF was not modulated by the previously attended level (global/local). These results support the DFF theory that top-down attentional selection of SF mediates global and local processing.

  8. Relativity evaluation of reliability on operation in nuclear power plant

    Inata, Takashi

    1987-01-01

    The report presents a quantitative method for evaluating the reliability of operations conducted in nuclear power plants. The quantitative reliability evaluation method is based on the 'detailed block diagram analysis (De-BDA)'. All units of a series of operations are separately displayed for each block and combined sequentially. Then, calculation is performed to evaluate the reliability. Basically, De-BDA calculation is made for pairs of operation labels, which are connected in parallel or in series at different subordination levels. The applicability of the De-BDA method is demonstrated by carrying out calculation for three model cases: operations in the event of malfunction of the control valve in the main water supply system for PWR, switching from an electrically-operated water supply pump to a turbin-operated water supply pump, and isolation and water removal operation for a low-pressure condensate pump. It is shown that the relative importance of each unit of a series of operations can be evaluated, making it possible to extract those units of greater importance, and that the priority among the factors which affect the reliability of operations can be determined. Results of the De-BDA calculation can serve to find important points to be considered in developing an operation manual, conducting education and training, and improving facilities. (Nogami, K.)

  9. Gendered Help at the Workplace: Implications for Organizational Power Relations.

    Chernyak-Hai, Lily; Waismel-Manor, Ronit

    2018-01-01

    One of the most thoroughly studied aspects of prosocial workplace behavior is organizational citizenship behavior (OCB). Yet, the definition of OCB seems to overlook the fact that help-giving acts may be of different types with different consequences for both giver and recipient. The present research explores workplace help-giving behavior by investigating the importance of gender as a factor that facilitates or inhibits specific types of help that empower and disempower independent coping: autonomy- and dependency-oriented help, respectively. A pilot and two following studies were conducted. The pilot study empirically assessed which acts would be clearly perceived by participants as representing both types of help. Then, using the descriptions of these acts, Study 1 examined which type of help would be perceived as most likely to be given by a male or female employee to a male or female colleague in a sample of 226 participants (78% women). Study 2 explored which type of help participants perceived as one they would rather receive from a male or female helper in a sample of 170 participants (65% women). Our findings indicate that male and female respondents who rated men giving help were more likely to expect them to give autonomy-oriented help, especially to women. There were no significant differences in dependency-oriented help. Further, women preferred to receive more autonomy-oriented help than men did, regardless of the help-giver's gender; no significant results were found for men. Implications for OCB and workplace power relations are discussed.

  10. Physical mechanisms of spring and summertime drought related with the global warming over the northern America

    Choi, W.; Kim, K. Y.

    2017-12-01

    Drought during the growing season (spring through summer) is severe natural hazard in the large cropland over the northern America. It is important to understand how the drought is related with the global warming and how it will change in the future. This study aims to investigate the physical mechanism of global warming impact on the spring and summertime drought over the northern America using Cyclostationary Empirical Orthogonal Function (CSEOF) analysis. The Northern Hemisphere surface warming, the most dominant mode of the surface air temperature, has resulted in decreased relative humidity and precipitation over the mid-latitude region of North America. For the viewpoint of atmospheric water demand, soil moisture and evaporation have also decreased significantly, exacerbating vulnerability of drought. These consistent features of changes in water demand and supply related with the global warming can provide a possibility of credible insight for future drought change.

  11. The rise of global health diplomacy: An interdisciplinary concept linking health and international relations.

    Chattu, Vijay Kumar

    2017-01-01

    Global health diplomacy (GHD) is relatively a very new field that has yet to be clearly defined and developed though there are various definitions given by different experts from foreign policy, global health, diplomacy, international relations, governance, and law. With the intensification of globalization and increasing gaps between countries, new and reemerging health threats such as HIV/AIDS, tuberculosis, influenza, severe acute respiratory syndrome, Ebola, and Zika and a gradual rethinking on security concepts framed a new political context. The health problems addressed diplomatically have also become diverse ranging from neglected tropical diseases, infectious diseases, sale of unsafe, counterfeit drugs to brain drain crisis. We see that global health has become more diverse as the actors widened and also the interests appealing not only to the traditional humanitarian ideals associated with health but also to the principles grounded in national and global security. Recently, we are witnessing the increased priority given to the GHD because the issue of health is discussed by various actors outside the WHO to shape the global policy for health determinants. In fact, the area of health has become the part of UN Summit Diplomacy involving the G8, G20, BRICS, and the EU. The recent WHO Pandemic Influenza Framework, UN High Level Framework on Prevention and Control of Noncommunicable Diseases, and the WHO Framework Convention on Tobacco Control are some of the examples of long-term negotiation processes for agreements that took place.

  13. From technology transfer to local manufacturing: China's emergence in the global wind power industry

    Lewis, Joanna Ingram

    This dissertation examines the development of China's large wind turbine industry, including the players, the status of the technology, and the strategies used to develop turbines for the Chinese market. The primary goals of this research project are to identify the models of international technology transfer that have been used among firms in China's wind power industry; examine to what extent these technology transfers have contributed to China's ability to locally manufacture large wind turbine technology; and evaluate China's ability to become a major player in the global wind industry. China is a particularly important place to study the opportunities for and dynamics of clean energy development due to its role in global energy consumption. China is the largest coal consuming and producing nation in the world, and consequently the second largest national emitter of carbon dioxide after only the United States. Energy consumption and carbon emissions are growing rapidly, and China is expected to surpass the US and become the largest energy consuming nation and carbon dioxide emitter in coming decades. The central finding of this dissertation is that even though each firm involved in the large wind turbine manufacturing industry in China has followed a very different pathway of technology procurement for the Chinese market, all of the firms are increasing the utilization of locally-manufactured components, and many are doing so without transferring turbine technology or the associated intellectual property. Only one fully Chinese-owned firm, Goldwind, has succeeded in developing a commercially available large wind turbine for the Chinese market. No Chinese firms or foreign firms are manufacturing turbines in China for export overseas, though many have stated plans to do so. There already exists a possible niche market for the smaller turbines that are currently being made in China, particularly in less developed countries that are looking for less expensive

    There are major differences in cancer drug prices around the world. However, the patterns of affordability of these drugs are poorly understood. The objective of this study was to compare patterns of affordability of cancer drugs in Australia, China, India, Israel, South Africa, the United Kingdom, and the United States. Cancer drug prices are highest in the United States. Cancer drugs are the least affordable in India by a large margin. Despite lower prices than in the USA, cancer drugs are less affordable in middle-income countries than in high-income countries. We obtained the prices of a basket of cancer drugs in all 7 countries, and converted the prices to US$ using both foreign exchange rates and purchasing power parity. We assessed international differences in wealth by collecting values for gross domestic product (GDP) per capita in addition to average salaries. We compared patterns of affordability of cancer drugs by dividing the drug prices by the markers of wealth. Cancer drugs are less affordable in middle-income countries than in high-income countries. Differential pricing may be an acceptable policy to ensure global affordability and access to highly active anti-cancer therapies.

  16. Power Deals. Mergers and acquisitions activity within the global electricity and gas market. 2006 Annual Review

    2007-01-01

    2006 was another recordbreaking year in the electricity and gas utilities sector. Total deal values shot through the record level set in 2005 to reach a dizzying USD 298.8bn. This is nearly seven times the USD 43bn level of transactions recorded in the sector only three years earlier in 2003. The rise is all the more astonishing as it comes in a year when deal activity from corporate US utility players plummeted. The sharp downturn in North America came as companies took stock of aggressive regulatory stances from some state regulators during a US midterm election year that coincided with the ending of rate freezes and reaction to the repeal of the Public Utilities Holding Company Act. North American electricity deal values by bidder fell 64% to USD 20.7bn, not far above the USD 16.7bn level of 2003. The picture in Europe and the Asia Pacific region was very different. Both regions recorded record levels of power deal activities as utility companies continued to strive for super regional'' scale. Deal activity in Europe was given extra momentum by the countdown to the July 2007 implementation of full retail market liberalisation. This report examines the rationale behind the overall trends and the key individual deals. We also highlight, in a series of deal dialogues throughout the report, some of the critical issues for companies engaging in deal activity within the sector drawing on our global experience as an adviser to players in major deals throughout the sector in all key power and gas markets. Looking to the future, the regulatory environment will play a key role in determining the course of deal activity. Companies entering into big deals need to be ready more than ever for the long haul. However, the underpinning momentum in the sector remains strong and this is likely to create continued buoyancy in the period ahead

    2006 was another recordbreaking year in the electricity and gas utilities sector. Total deal values shot through the record level set in 2005 to reach a dizzying USD 298.8bn. This is nearly seven times the USD 43bn level of transactions recorded in the sector only three years earlier in 2003. The rise is all the more astonishing as it comes in a year when deal activity from corporate US utility players plummeted. The sharp downturn in North America came as companies took stock of aggressive regulatory stances from some state regulators during a US midterm election year that coincided with the ending of rate freezes and reaction to the repeal of the Public Utilities Holding Company Act. North American electricity deal values by bidder fell 64% to USD 20.7bn, not far above the USD 16.7bn level of 2003. The picture in Europe and the Asia Pacific region was very different. Both regions recorded record levels of power deal activities as utility companies continued to strive for super regional'' scale. Deal activity in Europe was given extra momentum by the countdown to the July 2007 implementation of full retail market liberalisation. This report examines the rationale behind the overall trends and the key individual deals. We also highlight, in a series of deal dialogues throughout the report, some of the critical issues for companies engaging in deal activity within the sector drawing on our global experience as an adviser to players in major deals throughout the sector in all key power and gas markets. Looking to the future, the regulatory environment will play a key role in determining the course of deal activity. Companies entering into big deals need to be ready more than ever for the long haul. However, the underpinning momentum in the sector remains strong and this is likely to create continued buoyancy in the period ahead.

  19. Age-related changes in oscillatory power affect motor action.

    Liqing Liu

    Full Text Available With increasing age cognitive performance slows down. This includes cognitive processes essential for motor performance. Additionally, performance of motor tasks becomes less accurate. The objective of the present study was to identify general neural correlates underlying age-related behavioral slowing and the reduction in motor task accuracy. To this end, we continuously recorded EEG activity from 18 younger and 24 older right-handed healthy participants while they were performing a simple finger tapping task. We analyzed the EEG records with respect to local changes in amplitude (power spectrum as well as phase locking between the two age groups. We found differences between younger and older subjects in the amplitude of post-movement synchronization in the β band of the sensory-motor and medial prefrontal cortex (mPFC. This post-movement β amplitude was significantly reduced in older subjects. Moreover, it positively correlated with the accuracy with which subjects performed the motor task at the electrode FCz, which detects activity of the mPFC and the supplementary motor area. In contrast, we found no correlation between the accurate timing of local neural activity, i.e. phase locking in the δ-θ frequency band, with the reaction and movement time or the accuracy with which the motor task was performed. Our results show that only post-movement β amplitude and not δ-θ phase locking is involved in the control of movement accuracy. The decreased post-movement β amplitude in the mPFC of older subjects hints at an impaired deactivation of this area, which may affect the cognitive control of stimulus-induced motor tasks and thereby motor output.

  20. Nuclear power: renaissance or relapse? Global climate change and long-term Three Mile Island activists' narratives.

    Culley, Marci R; Angelique, Holly

    2010-06-01

    Community narratives are increasingly important as people move towards an ecologically sustainable society. Global climate change is a multi-faceted problem with multiple stakeholders. The voices of affected communities must be heard as we make decisions of global significance. We document the narratives of long-term anti-nuclear activists near the Three Mile Island (TMI) nuclear power plant who speak out in the dawn of a nuclear renaissance/relapse. While nuclear power is marketed as a "green" solution to global warming, their narratives reveal three areas for consideration; (1) significant problems with nuclear technology, (2) lessons "not" learned from the TMI disaster, and (3) hopes for a sustainable future. Nuclear waste, untrustworthy officials and economic issues were among the problems cited. Deceptive shaping of public opinion, nuclear illiteracy, and an aging anti-nuclear movement were reasons cited for the lessons not learned. However, many remain optimistic and envision increased participation to create an ecologically-balanced world.

  1. A statement on safety and related topics respecting nuclear power

    1982-01-01

    It is stated that nuclear power is remarkably safe and certainly safer than power from coal or oil. Waste presents no genuine problem in terms of storage, disposal or quantity while the ecological environmental impact is less than that of virtually all possible alternatives. Use of nuclear power can make the UK independent of external politically unreliable sources of energy. There are ethical arguments for choosing it in preference to coal or oil and it is broadly irrelevant to the question of nuclear proliferation. (U.K.)

  2. Global Ordo-Liberalism, Private Power and the Transfiguration of Diplomatic Law

    Noe Cornago

    2013-10-01

    Full Text Available Diplomatic law is commonly depicted as a field of law particularly differentiated and stable, and apparently at least not particularly vulnerable to the tensions associated to the restructuring of the global political economy which are so easily observable in other fields of international law. For centuries its formative process was customary. Later, early diplomatic practices, institutions, and norms were tailored to measure the functional and normative needs of a world of nation States. However, it was not until the signing in 1961 of the Vienna Convention on Diplomatic Relations that its basic rules were formally codified. But, as the preamble in this Convention affirms, the rules of customary law continue to govern all questions not expressly regulated by its contents. Custom however is not always the residue of the past that some practitioners and scholars use to imagine. Moreover, its formative processes are also embedded in wider historical transformations of global capitalism. Through the examination of current transformations affecting diplomatic settlement of disputes, diplomatic protection, diplomatic immunity and diplomatic reciprocity, this article contends that diplomatic law is becoming another field of struggle, both particularly unexpected and revealing, in the current transition from embedded liberalism towards a new era of global ordo-liberalism. El derecho diplomático se representa comúnmente como una rama del derecho especialmente diferenciada y estable, y aparentemente al menos no particularmente vulnerable a las tensiones asociadas a la reestructuración de la economía política global, que son tan fácilmente observables en otros ámbitos del derecho internacional. Su proceso formativo era habitual durante siglos. Más tarde , las tempranas prácticas diplomáticas, instituciones y normas se adaptaban para medir las necesidades funcionales y normativas de un mundo de estados naciones. Sin embargo, no fue hasta la firma

  3. Relative power and coherence of EEG series are related to amnestic mild cognitive impairment in diabetes

    Zhijie eBian

    2014-02-01

    Full Text Available Objective: Diabetes is a risk factor for dementia and mild cognitive impairment. The aim of this study was to investigate whether some features of resting-state EEG (rsEEG could be applied as a biomarker to distinguish the subjects with amnestic mild cognitive impairment (aMCI from normal cognitive function in type 2 diabetes. Materials and Methods: In this study, 28 patients with type 2 diabetes (16 aMCI patients and 12 controls were investigated. Recording of the rsEEG series and neuropsychological assessments were performed. The rsEEG signal was first decomposed into delta, theta, alpha, beta, gamma frequency bands. The relative power of each given band/sum of power and the coherence of waves from different brain areas were calculated. The extracted features from rsEEG and neuropsychological assessments were analyzed as well. Results: The main findings of this study were that: 1 compared with the control group, the ratios of power in theta band (P(theta versus power in alpha band (P(alpha (P(theta/P(alpha in the frontal region and left temporal region were significantly higher for aMCI, and 2 for aMCI, the alpha coherences in posterior, fronto-right temporal, fronto-posterior, right temporo-posterior were decreased; the theta coherences in left central-right central (LC-RC and left posterior-right posterior (LP-RP regions were also decreased; but the delta coherences in left temporal-right temporal (LT-RT region were increased. Conclusion: The proposed indexes from rsEEG recordings could be employed to track cognitive function of diabetic patients and also to help in the diagnosis of those who develop aMCI.

  4. Relative radiation hazards of coal based and nuclear power plants

    Mishra, U.C.

    1983-04-01

    Coal, like most materials found in nature, contains trace quantities of naturally occurring radionuclides. However, low concentrations may become important if large quantities of coal are burnt in thermal power plants. Therefore a study was performed to determine the radioactivity in coal, in fly-ash and slag and assess the importance of radioactive emissions from thermal power plants. The results were compared to the radiological impact of nuclear power stations. Based on these data, theoretical estimates for the population living within 80km from power stations indicate that the collective dose commitments of coal-fired plants are one order of magnitude higher than those for BWR-type nuclear plants. Measurements taken in the vicinity of coal-fired plants were comparable to those for nuclear plants, i.e. within the range of variation of natural background radiation in India

    This book explains the science behind the concerns that our nation faces in the immediate future. It outlines the tools of terrorists, the dangers of nuclear power, and the reality of global warming. As citizens who will elect future presidents of the most powerful and influential countries in the world, we need to know-truly understand if Iran's nascent nuclear capability is a genuine threat to the West, if biochemical weapons are likely to be developed by terrorists, if there are viable alternatives to fossil fuels that should be nurtured and supported by the government, if nuclear power should be encouraged, and if global warming is actually happening. This book is written in everyday, nontechnical language on the science behind the concerns that our nations faces in the immediate future.

  10. Flexible mechanisms in the corporate greenhouse: implementation of the Kyoto Protocol and the globalization of the electric power industry

    Schreuder, Y.; Sherry, C. [University of Delaware, Newark, DE (United States). Center for Energy and Environmental Policy

    2001-07-01

    The contradictions and unresolved tensions between economic globalization and climate change negotiations have added urgency to the climate change debate. The paper argues that the declining role of the nation state in the global economy and the increasing reach of transnational corporations throughout the world present a serious challenge to the environmental integrity and success of international environmental treaties such as the Kyoto Protocol. In particular efficacy and equity of the flexible mechanism under the Kyoto Protocol are questioned as illustrated by the patterns of Foreign Direct Investment (FDI) of the US electric power industry in the developing world. US FDI in the electric power sectors of developing countries supports continued carbon-intensive development patterns which will make the long-term goals of the Kyoto Protocol more difficult to achieve. Consequently, FDI raises questions about justifiability of giving credit to Annex I countries through CDM projects undertaken by transnational electric power corporations. 13 refs.

  16. Economic opportunities resulting from a global deployment of concentrated solar power (CSP) technologies-The example of German technology providers

    Vallentin, Daniel; Viebahn, Peter

    2010-01-01

    Several energy scenario studies consider concentrated solar power (CSP) plants as an important technology option to reduce the world's CO 2 emissions to a level required for not letting the global average temperature exceed a threshold of 2-2.4 o C. A global ramp up of CSP technologies offers great economic opportunities for technology providers as CSP technologies include highly specialised components. This paper analyses possible value creation effects resulting from a global deployment of CSP until 2050 as projected in scenarios of the International Energy Agency (IEA) and Greenpeace International. The analysis focuses on the economic opportunities of German technology providers since companies such as Schott Solar, Flabeg or Solar Millennium are among the leading suppliers of CSP technologies on the global market.

  18. Multistage and multiobjective formulations of globally optimal upgradable expansions for electric power distribution systems

    Vaziri Yazdi Pin, Mohammad

    Electric power distribution systems are the last high voltage link in the chain of production, transport, and delivery of the electric energy, the fundamental goals of which are to supply the users' demand safely, reliably, and economically. The number circuit miles traversed by distribution feeders in the form of visible overhead or imbedded underground lines, far exceed those of all other bulk transport circuitry in the transmission system. Development and expansion of the distribution systems, similar to other systems, is directly proportional to the growth in demand and requires careful planning. While growth of electric demand has recently slowed through efforts in the area of energy management, the need for a continued expansion seems inevitable for the near future. Distribution system and expansions are also independent of current issues facing both the suppliers and the consumers of electrical energy. For example, deregulation, as an attempt to promote competition by giving more choices to the consumers, while it will impact the suppliers' planning strategies, it cannot limit the demand growth or the system expansion in the global sense. Curiously, despite presence of technological advancements and a 40-year history of contributions in the area, many of the major utilities still relay on experience and resort to rudimentary techniques when planning expansions. A comprehensive literature review of the contributions and careful analyses of the proposed algorithms for distribution expansion, confirmed that the problem is a complex, multistage and multiobjective problem for which a practical solution remains to be developed. In this research, based on the 15-year experience of a utility engineer, the practical expansion problem has been clearly defined and the existing deficiencies in the previous work identified and analyzed. The expansion problem has been formulated as a multistage planning problem in line with a natural course of development and industry

  19. Electrofishing power requirements in relation to duty cycle

    Miranda, L.E.; Dolan, C.R.

    2004-01-01

    Under controlled laboratory conditions we measured the electrical peak power required to immobilize (i.e., narcotize or tetanize) fish of various species and sizes with duty cycles (i.e., percentage of time a field is energized) ranging from 1.5% to 100%. Electrofishing effectiveness was closely associated with duty cycle. Duty cycles of 10-50% required the least peak power to immobilize fish; peak power requirements increased gradually above 50% duty cycle and sharply below 10%. Small duty cycles can increase field strength by making possible higher instantaneous peak voltages that allow the threshold power needed to immobilize fish to radiate farther away from the electrodes. Therefore, operating within the 10-50% range of duty cycles would allow a larger radius of immobilization action than operating with higher duty cycles. This 10-50% range of duty cycles also coincided with some of the highest margins of difference between the electrical power required to narcotize and that required to tetanize fish. This observation is worthy of note because proper use of duty cycle could help reduce the mortality associated with tetany documented by some authors. Although electrofishing with intermediate duty cycles can potentially increase effectiveness of electrofishing, our results suggest that immobilization response is not fully accounted for by duty cycle because of a potential interaction between pulse frequency and duration that requires further investigation.

  20. Global nuclear survey: Public support for new power plants remains tentative

    2005-01-01

    14 of the 18 countries - and pluralities in the remaining four countries - believes that the risk of terrorist acts involving radioactive materials and nuclear facilities is high because of insufficient protection. A majority of 54 percent across all countries surveyed believe the risk of nuclear terrorism to be high, while three in ten (28%) say that the risk is low; 3) People appreciate the value of nuclear technology. When asked to consider the peaceful uses of nuclear technology, people in all but three countries are most supportive, by far, of medical applications, followed by electricity generation. Across the 18 countries surveyed, respondents are most likely to choose the use of nuclear technology to treat human diseases as their preferred application (39%). This is followed by electricity generation (26%); 4) Stressing the climate benefits of nuclear energy positively influences one in ten people to be more supportive of expanding the role of nuclear power in the world, but there is still a general reluctance to build more nuclear plants; 5) Awareness of the IAEA among the general population is generally low. However, one in four citizens across the 18 countries surveyed say that they have heard or read 'a lot' or 'some' about the agency, with higher awareness in Asia and the Middle East. The full report, Global Public Opinion on Nuclear Issues and the IAEA - Final Report from 18 Countries, is being released today by the IAEA in Vienna. The countries surveyed included: Argentina, Australia, Cameroon, Canada, France, Germany, the United Kingdom, Hungary, India, Indonesia, Japan, Jordan, Mexico, Morocco, Russia, Saudi Arabia, South Korea, and the United States.

  1. Avoidance of singularity and global non-conservation of energy in general relativity

    Verma, M.M.

    2009-06-01

    We show that the singularity in the General Theory of Relativity (GTR) is the expression of a non-Machian feature. It can be avoided with a scale-invariant dynamical theory, a property lacking in GTR. It is further argued that the global non-conservation of energy in GTR also results from the lack of scale-invariance, and the field formulation presented by several authors can only partly resolve the problem. Assuming the global energy conservation, we propose a negative energy density component with a positive equation of state that can drive the late-time acceleration in the universe, while the positive component confines to smaller scales.

  2. ICRF power limitation relation to density limit in ASDEX

    Ryter, F.

    1992-01-01

    Launching high ICRF power into ASDEX plasmas required good antenna-plasma coupling. This could be achieved by sufficient electron density in front of the antennas i.e. small antenna-plasma distance (1-2 cm) and moderate to high line-averaged electron density compared to the density window in ASDEX. These are conditions eventually close to the density limit. ICRF heated discharges terminated by plasma disruptions caused by the RF pulse limited the maximum RF power which can be injected into the plasma. The disruptions occurring in these cases have clear phenomenological similarities with those observed in density limit discharges. We show in this paper that the ICRF-power limitation by plasma disruptions in ASDEX was due to reaching the density limit. (orig.)

  3. Human resource issues related to an expanding nuclear power programme

    2006-05-01

    The IAEA Technical Working Group on Training and Qualification of Nuclear Power Plant Personnel recommended that the IAEA develop guidelines on human resource management (including staffing) and training/education programmes for new nuclear power plant (NPP) designs. This recommendation was made in recognition that these future NPPs may have significantly different needs in this area compared to operating plants, and if so, NPP operating organizations should integrate these needs into their planning for future NPP projects. This report is primarily intended for use by NPP operating organizations that already have units in operation and that are considering adding to their fleet. Therefore, the addition of both new and current designs are addressed in this report. However, it should also be of value to those organizations that are considering the initial implementation of nuclear power, as well as decision makers in government, and in other nuclear industry organizations

  5. Aspects related to the decommissioning of the nuclear power plants

    Goicea, Andrei; Andrei, Veronica

    2003-01-01

    All power plants, either coal, gas or nuclear, at the end of their life needs to be decommissioned and demolished and thus, to made the site available for other uses. The first generation nuclear power plants were designed for a life of about 30 years and some of them proved capable of continuing well beyond this term. Newer plants have been designed for a 40 to 60 years operating life. To date, other 90 commercial power reactors have been retired from operation. For nuclear power plants and nuclear facilities in general the decommissioning process consists of some or all of the following activities: the safe management of nuclear materials held in the facility, cleaning-up of radioactivity (decontamination), plant dismantling, progressive demolition of the plant and site remediation. Following the decommissioning, the regulatory controls covering facility end, partially or totally, and the safe site is released for appropriate alternative use. Cernavoda NPP is a young plant and it can benefit from the continuously developing experience of the decommissioning process at the international level. The current experience allows the most metallic parts of a nuclear power to be decontaminated and recycled and makes available proven techniques and equipment to dismantle nuclear facilities safely. As experience is gained, decommissioning costs for nuclear power plants, including disposal of associated wastes, are reducing and thus, contribute in a smaller fraction to the total cost of electricity generation. The new specific Romanian regulations establish a funding system for decommissioning and provisions for long-term radioactive waste management. In the near future a decommissioning plan will be made available for Cernavoda NPP. Since the plant has only 7 years operation, that plan can be improved in order to benefit from international experience that is growing. (authors)

  6. Simulations research of the global predictive control with self-adaptive in the gas turbine of the nuclear power plant

    2007-01-01

    For further improving the dynamic control capabilities of the gas turbine of the nuclear power plant, this paper puts forward to apply the algorithm of global predictive control with self-adaptive in the rotate speed control of the gas turbine, including control structure and the design of controller in the base of expounding the math model of the gas turbine of the nuclear power plant. the simulation results show that the respond of the change of the gas turbine speed under the control algorithm of global predictive control with self-adaptive is ten second faster than that under the PID control algorithm, and the output value of the gas turbine speed under the PID control algorithm is 1%-2% higher than that under the control slgorithm of global predictive control with self-adaptive. It shows that the algorithm of global predictive control with self-adaptive can better control the output of the speed of the gas turbine of the nuclear power plant and get the better control effect.

  7. Employment within the power supply industry and the power supply related activities 2010; Sysselsatte i kraftnaeringen og kraftrelatert virksomhet 2010

    Thoen, Haavard

    2011-07-01

    The report's main objective is to investigate employment within the power supply industry and the power supply related activities. The report will describe the composition of employees in regard to sex, age and education. The power supply industry is defined in Statistics Norway's Standard Industrial Classification, as 'Production and distribution of electricity'. The group of companies related to power supply related activities employ similar persons in regard to education and occupation, typical to companies in the power supply industry. In the report, these two groups make up the power supply sector. In 2010 there were 18215 employees in the power supply sector. This constitutes an increase of nearly 12 per cent since 2004 and 1,7 per cent since 2008. The sex distribution of about 80 per cent men and 20 per cent women has been fairly stable since 2004. Compared to the private sector in general the power supply sector has a low share of women among its employees. In 2009 the level of education in the power supply sector was higher than for the private sector in general. Since 2004, the share of persons with higher education has increased from 27 to 33 per cent. Employees in the power supply sector are on an average older than the employees in the private sector. The employees have matured since 2004, but in the last few years, there have also been signs of fresh recruitment. The power supply industry had a net influx of 347 new employees, or 2 percent, in the period between 2009 and 2010. There were 1522 new employees and 1175 employees lost in the sector due to attrition, which gives a turnover rate of 20 percent. If we look at the supply of new employees who were also employed in 2009, 19 percent of female employees worked in temporary staff recruitment agencies. This indicates that temporary work was an entry gate to the power supply industry for many women. Among men, the building- and construction sector was the most common background for

  8. River ice implications related to water power production in Norway

    Asvall, R.P. [Norwegian Water Resources and Energy Directorate, Oslo (Norway). Hydrology Dept.

    2009-07-01

    Nearly 99 per cent of the electricity produced in Norway is based on water power. While the period of large power development is over, the current focus lies in developing small hydroelectric power plants. A new market based energy law was implemented in Norway in 1991 to achieve more efficient use of electricity production by means of market forces. Since water regulation influences ice conditions in lakes and rivers, this paper focused on the implications of changes in ice conditions. In Norway, the expected changes in ice conditions are taken into account when issuing permits for water regulations and schemes for water discharge because some waterways are used as winter roads. Follow-up includes both close and long term observations and measurements. The impact of variable price on power was also discussed, with particular reference to ice conditions in cases where water discharge occurs on rivers. This paper summarized selected ice problems and how they have been handled. The paper also included a summary of anticipated climatic changes relevant to ice conditions.

In Norway, the expected changes in ice conditions are taken into account when issuing permits for water regulations and schemes for water discharge because some waterways are used as winter roads. Follow-up includes both close and long term observations and measurements. The impact of variable price on power was also discussed, with particular reference to ice conditions in cases where water discharge occurs on rivers. This paper summarized selected ice problems and how they have been handled. The paper also included a summary of anticipated climatic changes relevant to ice conditions.

  11. What contribution can international relations make to the evolving global health agenda?

    Davies, Sara E

    2010-01-01

    This article presents two approaches that have dominated International Relations in their approach to the international politics of health. The statist approach, which is primarily security-focused, seeks to link health initiatives to a foreign or defence policy remit. The globalist approach, in contrast, seeks to advance health not because of its intrinsic security value but because it advances the well-being and rights of individuals. This article charts the evolution of these approaches and demonstrates why both have the potential to shape our understanding of the evolving global health agenda. It examines how the statist and globalist perspectives have helped shape contemporary initiatives in global health governance and suggests that there is evidence of an emerging convergence between the two perspectives. This convergence is particularly clear in the articulation of a number of UN initiatives in this area - especially the One World, One Health Strategic Framework and the Oslo Ministerial Declaration (2007) which inspired the first UN General Assembly resolution on global health and foreign policy in 2009 and the UN Secretary-General's note "Global health and foreign policy: strategic opportunities and challenges". What remains to be seen is whether this convergence will deliver on securing states' interest long enough to promote the interests of the individuals who require global efforts to deliver local health improvements.

  12. Relations between high and low power groups: the importance of legitimacy.

    Hornsey, Matthew J; Spears, Russell; Cremers, Iris; Hogg, Michael A

    2003-02-01

    Using a social identity perspective, two experiments examined the effects of power and the legitimacy of power differentials on intergroup bias. In Experiment 1, 125 math-science students were led to believe that they had high or low representation in a university decision-making body relative to social-science students and that this power position was either legitimate or illegitimate. Power did not have an independent effect on bias; rather, members of both high and low power groups showed more bias when the power hierarchy was illegitimate than when it was legitimate. This effect was replicated in Experiment 2 (N = 105). In addition, Experiment 2 showed that groups located within an unfair power hierarchy expected the superordinate power body to be more discriminatory than did those who had legitimately high or low power. The results are discussed in terms of their implications for group relations. Copyright 2003 Society for Personality and Social Psychology, Inc.

  13. Agenda setting for maternal survival: the power of global health networks and norms.

    Smith, Stephanie L; Rodriguez, Mariela A

    2016-04-01

    Nearly 300,000 women--almost all poor women in low-income countries--died from pregnancy-related complications in 2010. This represents a decline since the 1980s, when an estimated half million women died each year, but is still far higher than the aims set in the United Nations Millennium Development Goals (MDGs) at the turn of the century. The 1970s, 1980s and 1990 s witnessed a shift from near complete neglect of the issue to emergence of a network of individuals and organizations with a shared concern for reducing maternal deaths and growth in the number of organizations and governments with maternal health strategies and programmes. Maternal health experienced a marked change in agenda status in the 2000s, attracting significantly higher level attention (e.g. from world leaders) and greater resource commitments (e.g. as one issue addressed by US$40 billion in pledges to the 2010 Global Strategy for Women's and Children's Health) than ever before. Several differences between network and actor features, issue characteristics and the policy environment pre- and post-2000 help to explain the change in agenda status for global maternal mortality reduction. Significantly, a strong poverty reduction norm emerged at the turn of the century; represented by the United Nations MDGs framework, the norm set unusually strong expectations for international development actors to advance included issues. As the norm grew, it drew policy attention to the maternal health goal (MDG 5). Seeking to advance the goals agenda, world leaders launched initiatives addressing maternal and child health. New network governance and framing strategies that closely linked maternal, newborn and child health shaped the initiatives. Diverse network composition--expanding beyond a relatively narrowly focused and technically oriented group to encompass allies and leaders that brought additional resources to bear on the problem--was crucial to maternal health's rise on the agenda in the 2000s

  14. Navon's classical paradigm concerning local and global processing relates systematically to visual object classification performance.

    Gerlach, Christian; Poirel, Nicolas

    2018-01-10

    Forty years ago David Navon tried to tackle a central problem in psychology concerning the time course of perceptual processing: Do we first see the details (local level) followed by the overall outlay (global level) or is it rather the other way around? He did this by developing a now classical paradigm involving the presentation of compound stimuli; large letters composed of smaller letters. Despite the usefulness of this paradigm it remains uncertain whether effects found with compound stimuli relate directly to visual object recognition. It does so because compound stimuli are not actual objects but rather formations of elements and because the elements that form the global shape of compound stimuli are not features of the global shape but rather objects in their own right. To examine the relationship between performance on Navon's paradigm and visual object processing we derived two indexes from Navon's paradigm that reflect different aspects of the relationship between global and local processing. We find that individual differences on these indexes can explain a considerable amount of variance in two standard object classification paradigms; object decision and superordinate categorization, suggesting that Navon's paradigm does relate to visual object processing.

    2015-10-01

    Sensory phenomena, including premonitory urges, are experienced by patients with Tourette syndrome (TS) and obsessive-compulsive disorder (OCD). The goal of the present study was to investigate such phenomena related to tics, obsessive-compulsive symptoms (OCS), and global functioning in Japanese patients with TS. Forty-one patients with TS were assessed using the University of São Paulo Sensory Phenomena Scale (USP-SPS), the Premonitory Urge for Tics Scale (PUTS), the Yale Global Tic Severity Scale (YGTSS), the Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS), and the Global Assessment of Functioning (GAF) Scale. USP-SPS and PUTS total scores were significantly correlated with YGTSS total and vocal tics scores. Additionally, both sensory phenomena severity scores were significantly correlated with DY-BOCS total OCS scores. Of the six dimensional OCS scores, the USP-SPS scores were significantly correlated with measures of aggression and sexual/religious dimensions. Finally, the PUTS total scores were significantly and negatively correlated with GAF scores. By assessing premonitory urges and broader sensory phenomena, and by viewing OCS from a dimensional approach, this study provides significant insight into sensory phenomena related to tics, OCS, and global functioning in patients with TS.

  16. The global coastline dataset: the observed relation between erosion and sea-level rise

    Donchyts, G.; Baart, F.; Luijendijk, A.; Hagenaars, G.

    2017-12-01

    Erosion of sandy coasts is considered one of the key risks of sea-level rise. Because sandy coastlines of the world are often highly populated, erosive coastline trends result in risk to populations and infrastructure. Most of our understanding of the relation between sea-level rise and coastal erosion is based on local or regional observations and generalizations of numerical and physical experiments. Until recently there was no reliable global scale assessment of the location of sandy coasts and their rate of erosion and accretion. Here we present the global coastline dataset that covers erosion indicators on a local scale with global coverage. The dataset uses our global coastline transects grid defined with an alongshore spacing of 250 m and a cross shore length extending 1 km seaward and 1 km landward. This grid matches up with pre-existing local grids where available. We present the latest results on validation of coastal-erosion trends (based on optical satellites) and classification of sandy versus non-sandy coasts. We show the relation between sea-level rise (based both on tide-gauges and multi-mission satellite altimetry) and observed erosion trends over the last decades, taking into account broken-coastline trends (for example due to nourishments).An interactive web application presents the publicly-accessible results using a backend based on Google Earth Engine. It allows both researchers and stakeholders to use objective estimates of coastline trends, particularly when authoritative sources are not available.

  17. Field theories on conformally related space-times: Some global considerations

    Candelas, P.; Dowker, J.S.

    1979-01-01

    The nature of the vacua appearing in the relation between the vacuum expectation value of stress tensors in conformally flat spaces is clarified. The simple but essential point is that the relevant spaces should have conformally related global Cauchy surfaces. Some commonly occurring conformally flat space-times are divided into two families according to whether they are conformally equivalent to Minkowski space or to the Rindler wedge. Expressions, some new, are obtained for the vacuum expectation value of the stress tensor for a number of illustrative cases. It is noted that thermalization relates the Green's functions of these two families

  18. Final argument relating to the Canadian nuclear power program

    Robertson, J.A.L.

    1978-05-01

    This report is the second brief, and one of a number of documents, submitted by Atomic Energy of Canada Limited (AECL) to the Ontario Royal Commission on Electric Power Planning. It is intended to update the original brief (AECL--5800) with respect to those matters that emerged during the course of the hearings and which had not been fully anticipated in that brief, as well as to summarize the AECL position on the various issues. To enable it to qualify as a ''final argument'' it contains only evidence or material that has been presented to the Royal Commission and is provided with marginal notations identifying the source of each section. It is AECL's position that the Canadian nuclear power program provides a safe, proven and efficient means of making a needed contribution to electricity supply, while strengthening the economy through the deployment of indigenous technology and resources.

  19. Precipitation and total power consumption in the ionosphere: Global MHD simulation results compared with Polar and SNOE observations

    M. Palmroth

    2006-05-01

    Full Text Available We compare the ionospheric electron precipitation morphology and power from a global MHD simulation (GUMICS-4 with direct measurements of auroral energy flux during a pair of substorms on 28-29 March 1998. The electron precipitation power is computed directly from global images of auroral light observed by the Polar satellite ultraviolet imager (UVI. Independent of the Polar UVI measurements, the electron precipitation energy is determined from SNOE satellite observations on the thermospheric nitric oxide (NO density. We find that the GUMICS-4 simulation reproduces the spatial variation of the global aurora rather reliably in the sense that the onset of the substorm is shown in GUMICS-4 simulation as enhanced precipitation in the right location at the right time. The total integrated precipitation power in the GUMICS-4 simulation is in quantitative agreement with the observations during quiet times, i.e., before the two substorm intensifications. We find that during active times the GUMICS-4 integrated precipitation is a factor of 5 lower than the observations indicate. However, we also find factor of 2-3 differences in the precipitation power among the three different UVI processing methods tested here. The findings of this paper are used to complete an earlier objective, in which the total ionospheric power deposition in the simulation is forecasted from a mathematical expression, which is a function of solar wind density, velocity and magnetic field. We find that during this event, the correlation coefficient between the outcome of the forecasting expression and the simulation results is 0.83. During the event, the simulation result on the total ionospheric power deposition agrees with observations (correlation coefficient 0.8 and the AE index (0.85.

  20. Navigating Between Stealth Advocacy and Unconscious Dogmatism: The Challenge of Researching the Norms, Politics and Power of Global Health.

    Ooms, Gorik

    2015-06-16

    Global health research is essentially a normative undertaking: we use it to propose policies that ought to be implemented. To arrive at a normative conclusion in a logical way requires at least one normative premise, one that cannot be derived from empirical evidence alone. But there is no widely accepted normative premise for global health, and the actors with the power to set policies may use a different normative premise than the scholars that propose policies - which may explain the 'implementation gap' in global health. If global health scholars shy away from the normative debate - because it requires normative premises that cannot be derived from empirical evidence alone - they not only mislead each other, they also prevent and stymie debate on the role of the powerhouses of global health, their normative premises, and the rights and wrongs of these premises. The humanities and social sciences are better equipped - and less reluctant - to approach the normative debate in a scientifically valid manner, and ought to be better integrated in the interdisciplinary research that global health research is, or should be. © 2015 by Kerman University of Medical Sciences.

  1. The rise of smart customers. How consumer power will change the global power and utilities business. What the sector thinks

    NONE

    2011-09-15

    This report is the second in a two-part study, geared to helping power and utilities companies adapt their business strategies and customer handling in a new smart world. It explores the views of power and utilities leaders across 12 countries on how smart might change consumers' needs and behaviors, what new services they plan to offer and where they see the strongest new opportunities and competitors. We also compare these results with those of the first study, which examined the views of consumers and their appetite for new smart services.

  2. QUALITY-RELATED FUNDING IN ROMANIAN HIGHER EDUCATION THROUGHOUT 2003 – 2011: A GLOBAL ASSESSMENT

    Gabriel-Alexandru Vîiu

    2015-12-01

    Full Text Available The article explores quality-related funding and its global outcomes in the context of Romanian higher education by focusing on the funding allocations provided to public universities throughout a period of nine years based on their institutional performance on the quality indicators integrated in the funding algorithm. Global funding allocations between universities are analysed and a summative appraisal for the entire nine-year window is provided. The article also explores the relation between quality- related funding, institutional disciplinary profiles and the results of a comprehensive evaluation conducted in 2011 by the Ministry of Education to complete a classification of the universities. The main findings indicate a low overall impact of qualityrelated funding for many institutions, but also a clear pattern in which universities focused on science, technology, engineering and mathematics overwhelmingly outperformed mixed institutions, as well as those focused on humanities, arts and social sciences. Furthermore, the global quality-related funding outcomes of the 2003 – 2011 period studied in the paper are shown to be significantly associated with the results of the 2011 classification

  3. Empirical Global Relations Converting M S and m b to Moment Magnitude

    Scordilis, E. M.

    2006-04-01

    The existence of several magnitude scales used by seismological centers all over the world and the compilation of earthquake catalogs by many authors have rendered globally valid relations connecting magnitude scales a necessity. This would allow the creation of a homogeneous global earthquake catalog, a useful tool for earthquake research. Of special interest is the definition of global relations converting different magnitude scales to the most reliable and useful scale of magnitude, the moment magnitude, M W. In order to accomplish this, a very large sample of data from international seismological sources (ISC, NEIC, HRVD, etc.) has been collected and processed. The magnitude scales tested against M W are the surface wave magnitude, M S, the body wave magnitude, m b, and the local magnitude, M L. The moment magnitudes adopted have been taken from the CMT solutions of HRVD and USGS. The data set used in this study contains 20,407 earthquakes, which occurred all over the world during the time period 1.1.1976-31.5.2003, for which moment magnitudes are available. It is shown that well-defined relations hold between M W and m b and M S and that these relations can be reliably used for compiling homogeneous, with respect to magnitude, earthquake catalogs.

  4. Call-related factors influencing output power from mobile phones.

    Hillert, Lena; Ahlbom, Anders; Neasham, David; Feychting, Maria; Järup, Lars; Navin, Roshan; Elliott, Paul

    2006-11-01

    Mobile phone use is increasing but there is also concern for adverse health effects. Well-designed prospective studies to assess several health outcomes are required. In designing a study of mobile phone use, it is important to assess which factors need to be considered in classifying the exposure to radiofrequency fields (RF). A pilot study was performed in Sweden and in the UK 2002 to 2003 to test the feasibility of recruiting a cohort of mobile phone users from a random population sample and from mobile phone subscription lists for a prospective study. As one part of this pilot study, different factors were evaluated regarding possible influence on the output power of the phones. By local switch logging, information on calls made from predefined subscriptions or dedicated handsets were obtained and the output power of phones during calls made indoors and outdoors, in moving and stationary mode, and in rural as well in urban areas were compared. In this experiment, calls were either 1, 1.5 or 5 min long. The results showed that high mobile phone output power is more frequent in rural areas whereas the other factors (length of call, moving/stationary, indoor/outdoor) were of less importance. Urban and rural area should be considered in an exposure index for classification of the exposure to RF from mobile phones and may be assessed by first base station during mobile phone calls or, if this information is not available, possibly by using home address as a proxy.

  5. Nuclear power and related issues: the US outlook

    Burstein, S.

    1989-01-01

    The author notes there are now 108 nuclear units licensed to operate in the US and another 18 under construction or completed but not licensed; nuclear power provided 19.5% of US total electrical energy as of May 1988. One of the most disturbing items is the increase in operating and maintenance costs of US nuclear plants which, in some cases, exceed costs of coal-fired plants. US leadership in nuclear power has lost much momentum due primarily to institutional rather than technological problems. There are some indications, however, that the anti-nuclear fever of the past is receding, namely: (1) President Reagan recently endorsing the need for nuclear power by signing legislation extending Price-Anderson nuclear insurance protection; (2) a more favorable regulatory climate; (3) some progress on the nuclear waste problem; (4) more supportive public acceptance; (5) decommissioning activities; (6) increased attention of plant aging and 40-yr. license requirement; (7) radon concerns, ironically, because of conservation practices; and (8) substantial progress in advanced reactor technology

  6. Costs related to radioactive residues from nuclear power

    1988-06-01

    The nuclear power enterprises are responsible for proper actions for safe handling and final storage of spent nuclear fuel and radioactive waste from Swedish nuclear power facilities. The most important actions are to plan, build and operate necessary plants and systems. The nuclear power enterprises have designated Swedish Nuclear Fuel and Waste Management Co., (SKB), to perform these tasks. In this report calculations concerning costs to carry out these tasks are presented. The calculations are based upon a plan prepared by SKB. The plan is described in the report. As final storage of the long lived and highly radioactive waste is planned to take place in the 21st century continuing research and development may indicate new methods which may affect system design as well as costs in a simplifying way. Plants and systems already operational are: Transport systems for radioactive waste products; A central temporary storage for spent nuclear fuel, 'CLAB'; A final storage for radioactive waste from operating nuclear facilities, 'SFR 1'.

  7. Employment within the power supply industry and the power supply related activities; Sysselsatte i kraftnaeringen og kraftrelatert virksomhet 2011

    Thoen, Haavard

    2012-07-01

    The report's main objective is to investigate employment within the power supply industry and the power supply related activities. The report will describe the composition of employees in regard to sex, age and education. The power supply industry is defined in Statistics Norway's Standard Industrial Classification, as 'Production and distribution of electricity'. The group of companies related to power supply related activities employ similar persons in regard to education and occupation, typical to companies in the power supply industry. These two groups make up the power supply sector in this report. In 2011 there were 18 450 employees in the power supply sector. This constitutes an increase of nearly 13.5 per cent since 2004 and 1.1 per cent since 2010. The sex distribution of about 80 per cent men and 20 per cent women has been fairly stable since 2004. The power supply sector has a low share of women among its employees compared to the private sector in general. In 2011 the level of education in the power supply sector was higher than for the private sector in general. Since 2004, the share of persons with higher education has increased from 27 to 33 per cent. Employees in the power supply sector are on average older than employees in the private sector. The employees have matured since 2004, but in the last few years, there have also been signs of fresh recruitment. The power supply industry had a net influx of 380 new employees, in the period between 2009 and 2011. There were 1678 new employees and 1298 employees lost in the sector due to attrition. If we look at the supply of new employees who were also employed in 2010, 14.2 percent of female employees worked in temporary staff recruitment agencies. Temporary work seems to be an important entry gate to the power supply industry for women. Among men, the building- and construction sector was the most common background for new employees in the power supply industry. Among people who quit

  10. Premises and solutions regarding a global approach of gaseous pollutants emissions from the fossil fuel power plants in Romania

    Tutuianu, O.; Fulger, E.D.; Vieru, A.; Feher, M.

    1996-01-01

    This paper deals with the present state of RENEL (Romanian Electricity Authority) - controlled thermal power plants from the point of view of technical aspects, utilized fuels and pollutant emissions. National and international regulations are also analyzed as well as their implications concerning the management of pollutant atmospheric emissions of the plants of RENEL. Starting from these premises the paper points out the advantage of global approach of pollution problems and offers solutions already implemented by RENEL. This global approach will result in an optimization of costs implied in pollutant emission limitations as the most efficient solution were found and applied. Having in view this treatment of the pollution problems, RENEL has submitted to the Ministry of the Industries and to the Ministry of Waters, Forests and Environmental Protection a 'Convention on the limitation of CO 2 , SO 2 and NO x emissions produced in the thermal power plants of RENEL'.

  11. Global power production scenarios to 2100 and the dual role of forests: accelerated climate damage or regulating and provisioning ecosystem services?

    Callesen, Ingeborg

    The worlds' electrical power production is depending on the current energy infrastructure, and future investments in new power supply facilities using renewable and non-renewable energy sources. Continued growth in power production in the 21st century will cause global environmental change (GEC......). GEC with climate change as an important driver will affect the environment and the economy in multiple ways that can be summarized as losses of biodiversity and changing ecosystem services (ES), but with very diverse temporal and spatial impacts. In a simple global growth model for power production......, including non-renewable and renewable energy sources, the potential role of forest biomass is investigated. The demands for forest ecosystem services imposed by the global power production are assessed in the present study. Three global power supply scenarios to 2050 with different emphasis...

  12. A Relational Database of WHO Mortality Data Prepared to Facilitate Global Mortality Research

    Albert de Roos

    2015-09-01

    Full Text Available Detailed world mortality data such as collected by the World Health Organization gives a wealth of information about causes of death worldwide over a time span of 60 year. However, the raw mortality data in text format as provided by the WHO is not directly suitable for systematic research and data mining. In this Data Paper, a relational database is presented that is created from the raw WHO mortality data set and includes mortality rates, an ICD-code table and country reference data. This enriched database, as a corpus of global mortality data, can be readily imported in relational databases but can also function as the data source for other types of databases. The use of this database can therefore greatly facilitate global epidemiological research that may provide new clues to genetic or environmental factors in the origins of diseases.

  15. Global solar energy radiation in relation with electricity supply in Romania

    Zoran, Maria

    2001-01-01

    Solar energy is one of the most viable source of renewable energy being both clean and nonpolluting. Spiraling energy use and other human activities have led to measurable effects upon the global environment and climatic changes. There is increasing international concern particularly in the areas of global warming owing to the increase of carbon dioxide (CO 2 ) in the atmosphere and of other greenhouse gases as sulfur dioxide (SO 2 ), oxides of nitrogen (NOx), hydrogen sulfide H 2 S, diethyl sulfide (DMS), chlorofluorocarbons (CFCs), methane CH 4 , as well in the effect of depletion of ozone (O 3 ) layer in the stratosphere. Climatological and global solar radiation analysis for some Romanian zones with great solar energy potential are presented. Remote sensing data provided by satellites are used for radiative fluxes monitoring and solar energy mapping as well as for solar energy use assessment. The realistic technical potential for solar energy applications in Romania is substantial, over 40000 TJyear -1 . As average energy global solar radiation in horizontal plane lies between 1100 and 1300 kWhm -2 year -1 , solar energy using for electrical power supply being a reliable alternative. More than one half of Romania's area has a range of insolation period between 1200 and 1500 hours year -1 , at an overall average daily irradiation of 1000 - 1200 kWh m -2 . The most favorable area in Romania is the North - Western part of Black Sea coast with an insolation period above 2300 hours year -1 . A small part 140 TJyear -1 are used profitably and almost 10% of the installed 10 6 m 2 of collector area, is still in operation. (author)

  16. Relative Error Evaluation to Typical Open Global dem Datasets in Shanxi Plateau of China

    Zhao, S.; Zhang, S.; Cheng, W.

    2018-04-01

    Produced by radar data or stereo remote sensing image pairs, global DEM datasets are one of the most important types for DEM data. Relative error relates to surface quality created by DEM data, so it relates to geomorphology and hydrologic applications using DEM data. Taking Shanxi Plateau of China as the study area, this research evaluated the relative error to typical open global DEM datasets including Shuttle Radar Terrain Mission (SRTM) data with 1 arc second resolution (SRTM1), SRTM data with 3 arc second resolution (SRTM3), ASTER global DEM data in the second version (GDEM-v2) and ALOS world 3D-30m (AW3D) data. Through process and selection, more than 300,000 ICESat/GLA14 points were used as the GCP data, and the vertical error was computed and compared among four typical global DEM datasets. Then, more than 2,600,000 ICESat/GLA14 point pairs were acquired using the distance threshold between 100 m and 500 m. Meanwhile, the horizontal distance between every point pair was computed, so the relative error was achieved using slope values based on vertical error difference and the horizontal distance of the point pairs. Finally, false slope ratio (FSR) index was computed through analyzing the difference between DEM and ICESat/GLA14 values for every point pair. Both relative error and FSR index were categorically compared for the four DEM datasets under different slope classes. Research results show: Overall, AW3D has the lowest relative error values in mean error, mean absolute error, root mean square error and standard deviation error; then the SRTM1 data, its values are a little higher than AW3D data; the SRTM3 and GDEM-v2 data have the highest relative error values, and the values for the two datasets are similar. Considering different slope conditions, all the four DEM data have better performance in flat areas but worse performance in sloping regions; AW3D has the best performance in all the slope classes, a litter better than SRTM1; with slope increasing

  17. Power and Frequency Control as it Relates to Wind-Powered Generation

    Lacommare, Kristina S H

    2010-12-20

    This report is a part of an investigation of the ability of the U.S. power system to accommodate large scale additions of wind generation. The objectives of this report are to describe principles by which large multi-area power systems are controlled and to anticipate how the introduction of large amounts of wind power production might require control protocols to be changed. The operation of a power system is described in terms of primary and secondary control actions. Primary control is fast, autonomous, and provides the first-line corrective action in disturbances; secondary control takes place on a follow-up time scale and manages the deployment of resources to ensure reliable and economic operation. This report anticipates that the present fundamental primary and secondary control protocols will be satisfactory as wind power provides an increasing fraction of the total production, provided that appropriate attention is paid to the timing of primary control response, to short term wind forecasting, and to management of reserves for control action.

  19. Enhancement of the REMix energy system model. Global renewable energy potentials, optimized power plant siting and scenario validation

    Stetter, Daniel

    2014-04-10

    As electricity generation based on volatile renewable resources is subject to fluctuations, data with high temporal and spatial resolution on their availability is indispensable for integrating large shares of renewable capacities into energy infrastructures. The scope of the present doctoral thesis is to enhance the existing energy modelling environment REMix in terms of (i.) extending the geographic coverage of the potential assessment tool REMix-EnDaT from a European to a global scale, (ii.) adding a new plant siting optimization module REMix-PlaSMo, capable of assessing siting effects of renewable power plants on the portfolio output and (iii.) adding a new alternating current power transmission model between 30 European countries and CSP electricity imports from power plants located in North Africa and the Middle East via high voltage direct current links into the module REMix-OptiMo. With respect to the global potential assessment tool, a thorough investigation is carried out creating an hourly global inventory of the theoretical potentials of the major renewable resources solar irradiance, wind speed and river discharge at a spatial resolution of 0.45°x0.45°. A detailed global land use analysis determines eligible sites for the installation of renewable power plants. Detailed power plant models for PV, CSP, wind and hydro power allow for the assessment of power output, cost per kWh and respective full load hours taking into account the theoretical potentials, technological as well as economic data. The so-obtined tool REMix-EnDaT can be used as follows: First, as an assessment tool for arbitrary geographic locations, countries or world regions, deriving either site-specific or aggregated installable capacities, cost as well as full load hour potentials. Second, as a tool providing input data such as installable capacities and hourly renewable electricity generation for further assessments using the modules REMix-PlasMo and OptiMo.

  1. Significant change of predictions related to the future of nuclear power

    Dumitrache, Ion

    2002-01-01

    During the last two decades of the 20th century, nuclear power contribution increased slowly in the world. This trend was mainly determined by the commissioning of new nuclear power plants, NPP, in the non-developed countries, except for Japan and South Korea. Almost all the forecasts offered the image of the stagnant nuclear power business. Sweden, Germany, Holland and Belgium Governments made clear the intention to stop the production of electricity based on fission. Recently, despite the negative effects on nuclear power of the terrorism events of September 11, 2001, the predictions related to the nuclear power future become much more optimistic. USA, Japan, South Korea and Canada made clear that new NPPs will offer their significant electricity contribution several decades, even after years 2020-2030. Moreover, several old NPP from USA obtained the license for an additional 20 years period of operation. The analysis indicated that most of the existing NPP in USA may increase the level of the maximum global power defined by the initial design. In the European Union the situation is much more complicated. About 35% of the electricity is based now on fission. Several countries, like Sweden and Germany, maintain the position of phasing out the NPPs, as soon as the licensed life-time is over. Finland decided to build a new power plant. France is very favorable to nuclear power, but does not need more energy. In the UK several very old NPP will be shut down, and companies like BNFL and British Energy intend to build new NPP, based on Westinghouse or AECL-Canada advanced reactors. Switzerland and Spain are favorable to the future use of nuclear power. In the eastern part of Europe, almost all the countries intend to base their electricity production on coal, fission, hydro and gas, nuclear contribution being significant. The most impressive increases of nuclear power output are related to Asia; in China, from 2.2 Gwe in 1999, to 18.7 Gwe in 2020, reference case, or 10

  3. On accounting difficulties: Risks related to nuclear power

    Plot, Emmanuelle; Vidal, Olivier

    2014-01-01

    An extreme risk has a very slight probability but potentially heavy consequences. Despite the existence of three accountancy methods for dealing with them (provisions, contingent liabilities and insurance), the transposition of such risks into financial statements is based on a sequential analysis of both the probability of the risk happening and the ability to estimate the effects. This method keeps us from taking into account risks with a highly uncertain probability of occurrence, such as accidents at nuclear power plants - independently of the 'amount' at stake. As management reports from firms concerned by nuclear risks show, the diffusion of qualitative information does not offset this gap in bookkeeping

  5. Development trends in power economy and related particularities of nuclear power

    Belostockij, A.M.

    1975-01-01

    This article deals with a concept, presented by the International Institute for Applied Systems Analysis (IIASA), of future power-economic developments in the light of the energy crisis. Nuclear reactors are the foundation of the concept. The demands now made on them differ from the traditional demands as follows: whereas nuclear reactors used to be exclusively intended for generating power, they will have to serve in future for generating power and process heat. As a result of increasing shortage, natural hydrocarbons, petroleum, and natural gas will have to be replaced by synthetic hydrocarbons on the basis of coal gasification. It is expected that the process heat needed for this will be made available in good time by the HTR. (HR/LN) [de

  6. Current methodological questions of studying social-political relations of global society

    2010-01-01

    Full Text Available Identification and critical study of social-political aspects of contemporary society within conditions of globalization must start from the characteristics (essence of globalization as a process of human kind consolidation. Globalization represents a process of economic, political and cultural connecting of all separate mankind societies (specific societies into the one whole, into a 'World' - 'Global' society (mega-society on the Planet with many contradictions. It is a meaningful way for money to bring profit in a peaceful manner. It leads not only to expanding of economic power through transnational and multinational economic corporations, but also to imposing way of life, social organization and categorized value system of countries - protagonists of globalization to others, as indicators of their creative capabilities and specific forms of their appearance, specialty and durability. These and other changes, as well as multiple and versatile consequences that accompany them, indicate the necessity of constructing a new social approach in their scientific cognition, with full respect of not only social but also natural laws on cognition and estimation of accomplishing social life. The social and especially sociological sciences should investigate and excogitate the next areas of global reality of contemporary society in this context.

  8. Perspectives at the East European engineering companies in the field of power industry in the power-plant construction globalization conditions

    Ganchev, R.

    2001-01-01

    A large group of companies, institutes, boiler and power engineering work ect. from East European countries, currently in process of reorganization or already transformed into new-established private companies and corporations possess significant intellectual property in the field of thermal power technologies and equipment and broad experience in the design and the erection of thermal power plants. In many cases this know-how is not only competitive to that of the large companies of the West and of the Far East, but frequently it also proves to have a number of advantages. However, in the years of transition in these countries and simultaneous globalization, the owners of this potentials meet with difficulties and restrictions to realize it fully. Large investment projects - for new or replacement capacities or comprehensive rehabilitation or refurbishment of TPPs - are accessible only for the financially powerful EPC-contractors and key equipment suppliers, for which large bank credits are accessible. The near future perspective, for the scientists and experts that have accumulated this capital, is in the opportunity to employ the extensive experience and know-how of this firms in the forthcoming large-scale rehabilitation projects in these countries, and primarily, in the solution of specific problems, that have not been solved so far, provided that the projects are awarded not on the basis of the financial power of the contractors but on the basis of the efficiency of the proposed original solutions

  9. Power and behavioral approach orientation in existing power relations and the mediating effect of income

    Lammers, Joris; Stoker, Janka I.; Stapel, Diederik A.

    A large number of authors have observed that the experience of power increases behavioral approach tendencies. There are however some important unresolved problems. Predominantly, the literature relies on lab manipulations, priming, and student populations. This has resulted in low face validity.

    The energy crisis that experiences the world drives to carry to an extreme, the use of all energy sources which are available. The sources need to be connected to the electric network in their next point, requiring of electric-electronic interfaces. The traditional electric power systems are changing their characteristics, in what concerns to structure, operation and on overvoltage generation. This change is not taking place in coordinated form among the involved sectors. The interconnection of a Distributed Generator (DG) directly with the power system is objectionable and risky. It is required of an interconnection transformer which performs several functions. Rigid specifications do not exist in this respect, for the variety of systems in use in the world, nevertheless there are utilities recommendations. Overvoltages caused by the DG, which arise due to the change of structure of the electric system, are explained. The transformer connection selection, presents positive and negative aspects that impact the utility and the user in a different or many times in an antagonistic way. The phenomenon of balanced and unbalanced ferroresonance overvoltage is studied. This phenomenon can takes place when using DG, either with synchronous or asynchronous generator, and for any type of connection of the transformer. The necessary conditions so that the phenomenon appears are presented. Eight interconnection transformer connection ways were studied. It is concluded that the solutions to reach by means of the employment of the DG, offer technical-economic advantages so much to the utility as to the user. It is also concluded in this work that the more advisable interconnection type is function of the system connection type. (author)

  11. Internalisation of external cost in the power generation sector: Analysis with Global Multi-regional MARKAL model

    Rafaj, Peter; Kypreos, Socrates

    2007-01-01

    The Global MARKAL-Model (GMM), a multi-regional 'bottom-up' partial equilibrium model of the global energy system with endogenous technological learning, is used to address impacts of internalisation of external costs from power production. This modelling approach imposes additional charges on electricity generation, which reflect the costs of environmental and health damages from local pollutants (SO 2 , NO x ) and climate change, wastes, occupational health, risk of accidents, noise and other burdens. Technologies allowing abatement of pollutants emitted from power plants are rapidly introduced into the energy system, for example, desulphurisation, NO x removal, and CO 2 scrubbers. The modelling results indicate substantial changes in the electricity production system in favour of natural gas combined cycle, nuclear power and renewables induced by internalisation of external costs and also efficiency loss due to the use of scrubbers. Structural changes and fuel switching in the electricity sector result in significant reduction of emissions of both local pollution and CO 2 over the modelled time period. Strong decarbonisation impact of internalising local externalities suggests that ancillary benefits can be expected from policies directly addressing other issues then CO 2 mitigation. Finally, the detailed analysis of the total generation cost of different technologies points out that inclusion of external cost in the price of electricity increases competitiveness of non-fossil generation sources and fossil power plants with emission control

  14. Global outlook of nuclear power in the LDC's in the 1980's

    Malu wa Kalenga

    1981-01-01

    A programme is outlined which is sufficiently complex and capital intensive to warrant or to necessitate an international effort combining the resources and expertise of organizations such as the IAEA, the World Bank, OECD, OPEC fund, national organizations and firms, in order to tackle simultaneously: 1) the problem of education and manpower development, which is the main task of IAEA; 2) building a stronger international commitment to international financing of third world nuclear programmes, which will be the main task of World Bank, OECD, OPEC special funds; 3) devising buildings and testing the prototype of a small nuclear power reactor. This has to be done in a developed nation so that prospective buyers can see one in operation. To oversome the technical constraint related to such a project it will be necessary to help organize an international consortium which will first determine with the help of the IAEA the potential market for small reactor in the 200-400 MWe range, then select the best design and finally carry out the building and testing of the prototype. 4) to create and manage an international fuel bank in order to relieve developing countries of the considerable concerns about quaranted sources of supply.

  15. Global models underestimate large decadal declining and rising water storage trends relative to GRACE satellite data

    Scanlon, Bridget R.; Zhang, Zizhan; Save, Himanshu; Sun, Alexander Y.; van Beek, Ludovicus P. H.; Wiese, David N.; Reedy, Robert C.; Longuevergne, Laurent; Döll, Petra; Bierkens, Marc F. P.

    Assessing reliability of global models is critical because of increasing reliance on these models to address past and projected future climate and human stresses on global water resources. Here, we evaluate model reliability based on a comprehensive comparison of decadal trends (2002–2014) in land water storage from seven global models (WGHM, PCR-GLOBWB, GLDAS NOAH, MOSAIC, VIC, CLM, and CLSM) to trends from three Gravity Recovery and Climate Experiment (GRACE) satellite solutions in 186 river basins (∼60% of global land area). Medians of modeled basin water storage trends greatly underestimate GRACE-derived large decreasing (≤−0.5 km3/y) and increasing (≥0.5 km3/y) trends. Decreasing trends from GRACE are mostly related to human use (irrigation) and climate variations, whereas increasing trends reflect climate variations. For example, in the Amazon, GRACE estimates a large increasing trend of ∼43 km3/y, whereas most models estimate decreasing trends (−71 to 11 km3/y). Land water storage trends, summed over all basins, are positive for GRACE (∼71–82 km3/y) but negative for models (−450 to −12 km3/y), contributing opposing trends to global mean sea level change. Impacts of climate forcing on decadal land water storage trends exceed those of modeled human intervention by about a factor of 2. The model-GRACE comparison highlights potential areas of future model development, particularly simulated water storage. The inability of models to capture large decadal water storage trends based on GRACE indicates that model projections of climate and human-induced water storage changes may be underestimated.

  16. Nuclear power and the global challenges of energy security, 6 September 2007, London, England, World Nuclear Association Annual Symposium

    ElBaradei, M.

    2007-01-01

    In the Atoms for Peace speech given by US President Eisenhower in 1953 - the speech that paved the way for the creation of the IAEA - he declared that a special purpose of Atoms for Peace would be 'to provide abundant electrical energy in the power-starved areas of the world'. That vision has yet to be realized. And it should not be taken to mean that nuclear power is the solution for all countries, or for all developing countries. But I would reiterate what I said at the outset - that the global challenges of security and development are interlinked, and that addressing the energy security needs of all countries will be a key to progress on both fronts. It is incumbent upon us to see to it that nuclear power will fulfil its potential in addressing these challenges

  17. Intermittent 20-HZ-photic stimulation leads to a uniform reduction of alpha-global field power in healthy volunteers.

    Rau, R; Raschka, C; Koch, H J

    2001-01-01

    19-channel-EEGs were recorded from scalp surface of 30 healthy subjects (16m, 14f, mean age: 34 ys, SD: 11.7 ys) at rest and under IPS (Intermittent Photic Stimulation) at rates of 5, 10 and 20 Hertz (Hz). Digitalized data underwent spectral analysis with fast fourier transfomation (FFT) yielding the basis for the computation of global field power (GFP). For quantification GFP values in the frequency ranges of 5, 10 and 20 Hz at rest were divided by the corresponding data gained under IPS. While ratios from PDE data showed no stable parameter due to high interindividual variability, ratios of alpha-power turned out to be uniform in all subjects: IPS at 20 Hz always led to a suppression of alpha-power. Dividing alpha-GFP at rest by alpha-GFP under 20-Hz IPS thus resulted in a ratio paradigma.

  18. US/Japan workshop on mitigation and adaptation technologies related to global climate change

    Bernthal, F.M.

    1993-12-31

    It is a great pleasure for me to have the honor of delivering the keynote address for this important gathering, an honor enhanced further because of the many activities and historic relationships represented by this workshop. First of all, it represents the spirit of continuing cooperation and good relations between the United States and Japan. With the aid of the framework provided by the U.S./Japan Science and Technology Agreement, our two nations can come together to address a problem that has no national boundaries {hor_ellipsis} and we can think about solutions of potential benefit to all citizens of the global community. This workshop also symbolizes the spirit of cooperation so characteristic of the conduct of research in science and technology -- cooperation between us as individual scientists and engineers, between the various institutions we represent, and across our diverse disciplines. This workshop is only the second of its kind. The first US/Japan Workshop on global climate change was held last year in Japan. That workshop focused on cooperative scientific research in the United States and Japan. Out of it came a general agreement to continue collaborative work and to extend cooperation into the area of global change-related technologies, in particular those technologies that hold promise for mitigation and adaptation.

  19. Self-compassion versus global self-esteem: two different ways of relating to oneself.

    Neff, Kristin D; Vonk, Roos

    2009-02-01

    This research examined self-compassion and self-esteem as they relate to various aspects of psychological functioning. Self-compassion entails treating oneself with kindness, recognizing one's shared humanity, and being mindful when considering negative aspects of oneself. Study 1 (N=2,187) compared self-compassion and global self-esteem as they relate to ego-focused reactivity. It was found that self-compassion predicted more stable feelings of self-worth than self-esteem and was less contingent on particular outcomes. Self-compassion also had a stronger negative association with social comparison, public self-consciousness, self-rumination, anger, and need for cognitive closure. Self-esteem (but not self-compassion) was positively associated with narcissism. Study 2 (N=165) compared global self-esteem and self-compassion with regard to positive mood states. It was found that the two constructs were statistically equivalent predictors of happiness, optimism, and positive affect. Results from these two studies suggest that self-compassion may be a useful alternative to global self-esteem when considering what constitutes a healthy self-stance.

  20. Global search tool for the Advanced Photon Source Integrated Relational Model of Installed Systems (IRMIS) database

    Quock, D.E.R.; Cianciarulo, M.B.

    2007-01-01

    The Integrated Relational Model of Installed Systems (IRMIS) is a relational database tool that has been implemented at the Advanced Photon Source to maintain an updated account of approximately 600 control system software applications, 400,000 process variables, and 30,000 control system hardware components. To effectively display this large amount of control system information to operators and engineers, IRMIS was initially built with nine Web-based viewers: Applications Organizing Index, IOC, PLC, Component Type, Installed Components, Network, Controls Spares, Process Variables, and Cables. However, since each viewer is designed to provide details from only one major category of the control system, the necessity for a one-stop global search tool for the entire database became apparent. The user requirements for extremely fast database search time and ease of navigation through search results led to the choice of Asynchronous JavaScript and XML (AJAX) technology in the implementation of the IRMIS global search tool. Unique features of the global search tool include a two-tier level of displayed search results, and a database data integrity validation and reporting mechanism.

It originates from power imbalance in a social group, and can target anyone who qualifies as “different” in ...

  2. Providing all global energy with wind, water, and solar power, Part II: Reliability, system and transmission costs, and policies

    Delucchi, Mark A.; Jacobson, Mark Z.

    2011-01-01

    This is Part II of two papers evaluating the feasibility of providing all energy for all purposes (electric power, transportation, and heating/cooling), everywhere in the world, from wind, water, and the sun (WWS). In Part I, we described the prominent renewable energy plans that have been proposed and discussed the characteristics of WWS energy systems, the global demand for and availability of WWS energy, quantities and areas required for WWS infrastructure, and supplies of critical materials. Here, we discuss methods of addressing the variability of WWS energy to ensure that power supply reliably matches demand (including interconnecting geographically dispersed resources, using hydroelectricity, using demand-response management, storing electric power on site, over-sizing peak generation capacity and producing hydrogen with the excess, storing electric power in vehicle batteries, and forecasting weather to project energy supplies), the economics of WWS generation and transmission, the economics of WWS use in transportation, and policy measures needed to enhance the viability of a WWS system. We find that the cost of energy in a 100% WWS will be similar to the cost today. We conclude that barriers to a 100% conversion to WWS power worldwide are primarily social and political, not technological or even economic. - Research highlights: → We evaluate the feasibility of global energy supply from wind, water, and solar energy. → WWS energy can be supplied reliably and economically to all energy-use sectors. → The social cost of WWS energy generally is less than the cost of fossil-fuel energy. → Barriers to 100% WWS power worldwide are socio-political, not techno-economic.

  3. Relation of tolerance of ambiguity to global and specific paranormal experience.

    Houran, J; Williams, C

    1998-12-01

    We examined the relationship of tolerance of ambiguity to severe global factors and specific types of anomalous or paranormal experience. 107 undergraduate students completed MacDonald's 1970 AT-20 and the Anomalous Experiences Inventory of Kumar, Pekala, and Gallagher. Scores on the five subscales of the Anomalous Experiences Inventory correlated differently with tolerance of ambiguity. Global paranormal beliefs, abilities, experiences, and drug use were positively associated with tolerance of ambiguity, whereas a fear of paranormal experience showed a negative relation. The specific types of anomalous experiences that correlated with tolerance of ambiguity often involved internal or physiological experience, e.g., precognitive dreams, memories of reincarnation, visual apparitions, and vestibular alterations. We generally found no effects of age of sex. These results are consistent with the idea that some paranormal experiences are misattributions of internal experience to external ('paranormal') sources, a process analogous to mechanisms underpinning delusions and hallucinations.

  5. Autism and increased paternal age related changes in global levels of gene expression regulation.

    Mark D Alter

    2011-02-01

    Full Text Available A causal role of mutations in multiple general transcription factors in neurodevelopmental disorders including autism suggested that alterations in global levels of gene expression regulation might also relate to disease risk in sporadic cases of autism. This premise can be tested by evaluating for changes in the overall distribution of gene expression levels. For instance, in mice, variability in hippocampal-dependent behaviors was associated with variability in the pattern of the overall distribution of gene expression levels, as assessed by variance in the distribution of gene expression levels in the hippocampus. We hypothesized that a similar change in variance might be found in children with autism. Gene expression microarrays covering greater than 47,000 unique RNA transcripts were done on RNA from peripheral blood lymphocytes (PBL of children with autism (n = 82 and controls (n = 64. Variance in the distribution of gene expression levels from each microarray was compared between groups of children. Also tested was whether a risk factor for autism, increased paternal age, was associated with variance. A decrease in the variance in the distribution of gene expression levels in PBL was associated with the diagnosis of autism and a risk factor for autism, increased paternal age. Traditional approaches to microarray analysis of gene expression suggested a possible mechanism for decreased variance in gene expression. Gene expression pathways involved in transcriptional regulation were down-regulated in the blood of children with autism and children of older fathers. Thus, results from global and gene specific approaches to studying microarray data were complimentary and supported the hypothesis that alterations at the global level of gene expression regulation are related to autism and increased paternal age. Global regulation of transcription, thus, represents a possible point of convergence for multiple etiologies of autism and other

  6. Power plants 2020+. Power plant options for the future and the related demand for research

    2010-01-01

    This short overview already demonstrates that in the foreseeable future all generation options - nuclear power, fossil-fired power plants and renewable sources of energy - will continue to be applied. If, however, due to climate protection targets, energy conversion processes are to be to switched to CO 2 -free or -low carbon energy sources, comprehensive research endeavours will be required in order to advance existing technology options and to adjust them to changing conditions. This paper is bound to recommend individual fields of research from the viewpoint of the VGB Scientific Advisory Board for the period 2020 and beyond. Firstly, the generation structure in the European high-voltage grid and its development until 2020 will be considered, then the research demand for - Hard coal- and lignite-fired power plants, - Renewables-based electricity generation (wind, solar energy) and - Nuclear-based electricity generation will be outlined briefly, listing the main technology issues to be answered by researchers in order to increase efficiency and to settle any ''loose ends''. Apart from generation technologies, the options for storing electrical energy will also be dealt with. These options can contribute to make the feed-in of renewables-based electricity more permanent and sustainable. (orig.)

  8. Management of age-related degradation for nuclear power plants

    Gregor, Frank E.

    2004-01-01

    Life extension for nuclear power plants has been studied in the USA for the last six years, largely supported by EPRI, DOE and the USNRC. Though there are diverse opinions for the strategies and priorities of life extension and aging management, one common conclusion has been formulated regarding the need of current maintenance programs having to focus on aging and degradation management. Such program, called 'Maintenance Effectiveness Evaluation and Enhancement' or M3E for short, has been developed to assist plant operators to upgrade and enhance existing programs by integrating aging/degradation management activities for important or critical equipment and components. The key elements of the M3E program consist of the definition and selection of the critical components or commodities to be included in the scope, the survey/inventory of the current programs and their respective action steps, frequencies, corrective measures and extent of coverage, the component/commodity degradation mechanism, sites and severity, safety functions and service environments and lastly, the correlation of degradation/aging with the individual maintenance activities. The degree of correlation provides a measure of effectiveness and the opportunity to identify/specify needed enhancements, abandonment or generation of new maintenance activities. Implementation of the activities can then be prioritized at the option of the plant staff. (author)

  9. Safety related requirements on future nuclear power plants

    Niehaus, F.

    1991-01-01

    Nuclear power has the potential to significantly contribute to the future energy supply. However, this requires continuous improvements in nuclear safety. Technological advancements and implementation of safety culture will achieve a safety level for future reactors of the present generation of a probability of core-melt of less than 10 -5 per year, and less than 10 -6 per year for large releases of radioactive materials. There are older reactors which do not comply with present safety thinking. The paper reviews findings of a recent design review of WWER 440/230 plants. Advanced evolutionary designs might be capable of reducing the probability of significant off-site releases to less than 10 -7 per year. For such reactors there are inherent limitations to increase safety further due to the human element, complexity of design and capability of the containment function. Therefore, revolutionary designs are being explored with the aim of eliminating the potential for off-site releases. In this context it seems to be advisable to explore concepts where the ultimate safety barrier is the fuel itself. (orig.) [de

  10. Interpersonal Dominance in Relational Conflict: A View from Dyadic Power Theory

    Stacy L. Young

    2008-06-01

    Full Text Available This investigation uses dyadic power theory (Dunbar, 2004; Dunbar & Burgoon, 2005a; Rollins & Bahr, 1976 to offer competing hypotheses examining the relationship between power and dominance in close relationships. Forty-seven couples engaged in a conversation while being videotaped; the tapes were coded by third-party observers for dominance. Participants rated themselves to be the most dominant when they were equal to their partners in power, followed by those who perceived they were more powerful relative to their partners. Men and women had different perceptions of power and dominance in their relationships. Men’s perceptions of power were not related to their behavioral dominance whereas when women saw themselves as more powerful, they viewed their partners as more dominant.

  11. Global Crustal Dynamics of Magnetars in Relation to Their Bright X-Ray Outbursts

    This paper considers the yielding response of a neutron star crust to smooth, unbalanced Maxwell stresses imposed at the core–crust boundary, and the coupling of the dynamic crust to the external magnetic field. Stress buildup and yielding in a magnetar crust are global phenomena: an elastic distortion radiating from one plastically deforming zone is shown to dramatically increase the creep rate in distant zones. Runaway creep to dynamical rates is shown to be possible, being enhanced by in situ heating and suppressed by thermal conduction and shearing of an embedded magnetic field. A global and time-dependent model of elastic, plastic, magnetic, and thermal evolution is developed. Fault-like structures develop naturally, and a range of outburst timescales is observed. Transient events with time profiles similar to giant magnetar flares (millisecond rise, ∼0.1 s duration, and decaying power-law tails) result from runaway creep that starts in localized sub-kilometer-sized patches and spreads across the crust. A one-dimensional model of stress relaxation in the vertically stratified crust shows that a modest increase in applied stress allows embedded magnetic shear to escape the star over ∼3–10 ms, dissipating greater energy if the exterior field is already sheared. Several such zones coupled to each other naturally yield a burst of duration ∼0.1 s, as is observed over a wide range of burst energies. The collective interaction of many plastic zones forces an overstability of global elastic modes of the crust, consistent with quasi-periodic oscillation (QPO) activity extending over ∼100 s. Giant flares probably involve sudden meltdown in localized zones, with high-frequency (≫100 Hz) QPOs corresponding to standing Alfvén waves within these zones.

  12. Parametrized overview of CO_2 power cycles for different operation conditions and configurations – An absolute and relative performance analysis

    Cardemil, José M.; Silva, Alexandre K. da

    2016-01-01

    Highlights: • Thermodynamic modeling of CO_2-based power cycles. • A multi-parameter analysis for different cycle configurations. • Performance comparison between CO_2 and four other fluids. • Detailed discussion considering optimized operational parameters (i.e., pressure, HX size). • Overview of the technical applicability of the CO_2. - Abstract: This thermodynamically based study focuses on the thermal performance of power cycles using CO_2 as the working fluid. The work considers numerous aspects that can influence the cycle's performance, such as the type of cycle (i.e., Rankine or Brayton), its configuration (i.e., with and without a recuperator), and different operational conditions (i.e., heat source temperature and the upper and lower operating pressures of the CO_2). To account for all possible scenarios, a thermodynamic routine was especially implemented and linked to a library that contained all the thermodynamics properties of CO_2. The results are mostly presented in terms of the absolute and relative 1st and 2nd Law efficiencies of CO_2 as well as the cycle's scale, here represented by the global conductance (UA) of the heat exchangers used within the cycle. For the relative performance assessment, four other working fluids, commonly used in energy conversion cycles, were considered (i.e., ethane, toluene, D4 siloxane and water). As expected, the absolute performance results indicate a strong dependence of the cycle's efficiencies on the operational conditions. As for the relative performance, the results suggest that while the CO_2's 1st Law efficiency might be lower than other fluids, its exergetic efficiency can be significantly higher. Furthermore, the calculations also indicate that the CO_2's needed global conductance is potentially lower than competing fluids (e.g., toluene) for certain operational conditions, which suggests that CO_2-based power plants can be more compact, since they might require smaller heat exchangers to produce

  13. The future role of nuclear power in addressing global environmental problems

    Stumpf, W.

    1995-01-01

    Decision makers have to increasingly balance the costs versus benefits of various energy choices against a background of global environmental deterioration. This is particularly so in the choice of long term electricity production strategies where these have to be balanced against the potential of a very severe disruption of the world's climate due to global warming. In this presentation, the threat of global warming is quantified and scenarios are developed of future predicted energy consumption patterns and their impact on international policies to curb global warming, are analyzed. The conclusion is reached that the threat of global warming is so severe that, on the macro level, an international accepted strategy of utilising a proper balance between all forms of electricity production, is a matter of priority and that all national energy choices should be taken against this framework. Such strategic decisions on the macro level must, however, also translate into the micro level of energy production on topics which include: - more efficient plant utilisation; - more effective risk management; correct choice and application of technology; and - better understanding of issues concerning safety, quality and environmental impact.

  14. Entropy-power uncertainty relations: towards a tight inequality for all Gaussian pure states

    Hertz, Anaelle; Jabbour, Michael G; Cerf, Nicolas J

    2017-01-01

    We show that a proper expression of the uncertainty relation for a pair of canonically-conjugate continuous variables relies on entropy power, a standard notion in Shannon information theory for real-valued signals. The resulting entropy-power uncertainty relation is equivalent to the entropic formulation of the uncertainty relation due to Bialynicki-Birula and Mycielski, but can be further extended to rotated variables. Hence, based on a reasonable assumption, we give a partial proof of a tighter form of the entropy-power uncertainty relation taking correlations into account and provide extensive numerical evidence of its validity. Interestingly, it implies the generalized (rotation-invariant) Schrödinger–Robertson uncertainty relation exactly as the original entropy-power uncertainty relation implies Heisenberg relation. It is saturated for all Gaussian pure states, in contrast with hitherto known entropic formulations of the uncertainty principle. (paper)

  15. Quantitative Evaluation of MODIS Fire Radiative Power Measurement for Global Smoke Emissions Assessment

    Ichoku, Charles; Ellison, Luke

    2011-01-01

    Satellite remote sensing is providing us tremendous opportunities to measure the fire radiative energy (FRE) release rate or power (FRP) from open biomass burning, which affects many vegetated regions of the world on a seasonal basis. Knowledge of the biomass burning characteristics and emission source strengths of different (particulate and gaseous) smoke constituents is one of the principal ingredients upon which the assessment, modeling, and forecasting of their distribution and impacts depend. This knowledge can be gained through accurate measurement of FRP, which has been shown to have a direct relationship with the rates of biomass consumption and emissions of major smoke constituents. Over the last decade or so, FRP has been routinely measured from space by both the MODIS sensors aboard the polar orbiting Terra and Aqua satellites, and the SEVIRI sensor aboard the Meteosat Second Generation (MSG) geostationary satellite. During the last few years, FRP has steadily gained increasing recognition as an important parameter for facilitating the development of various scientific studies and applications relating to the quantitative characterization of biomass burning and their emissions. To establish the scientific integrity of the FRP as a stable quantity that can be measured consistently across a variety of sensors and platforms, with the potential of being utilized to develop a unified long-term climate data record of fire activity and impacts, it needs to be thoroughly evaluated, calibrated, and validated. Therefore, we are conducting a detailed analysis of the FRP products from MODIS to evaluate the uncertainties associated with them, such as those due to the effects of satellite variable observation geometry and other factors, in order to establish their error budget for use in diverse scientific research and applications. In this presentation, we will show recent results of the MODIS FRP uncertainty analysis and error mitigation solutions, and demonstrate

  16. Performance Improvement of Power Analysis Attacks on AES with Encryption-Related Signals

    Lee, You-Seok; Lee, Young-Jun; Han, Dong-Guk; Kim, Ho-Won; Kim, Hyoung-Nam

    A power analysis attack is a well-known side-channel attack but the efficiency of the attack is frequently degraded by the existence of power components, irrelative to the encryption included in signals used for the attack. To enhance the performance of the power analysis attack, we propose a preprocessing method based on extracting encryption-related parts from the measured power signals. Experimental results show that the attacks with the preprocessed signals detect correct keys with much fewer signals, compared to the conventional power analysis attacks.

  17. Politics and Power in Global Health: The Constituting Role of Conflicts

    Askheim, Clemet; Heggen, Kristin; Engebretsen, Eivind

    2016-01-01

    In a recent article, Gorik Ooms has drawn attention to the normative underpinnings of the politics of global health. We claim that Ooms is indirectly submitting to a liberal conception of politics by framing the politics of global health as a question of individual morality. Drawing on the theoretical works of Chantal Mouffe, we introduce a conflictual concept of the political as an alternative to Ooms’ conception. Using controversies surrounding medical treatment of AIDS patients in developing countries as a case we underline the opportunity for political changes, through political articulation of an issue, and collective mobilization based on such an articulation.

  18. Perceived reciprocal value of health professionals' participation in global child health-related work.

    Carbone, Sarah; Wigle, Jannah; Akseer, Nadia; Barac, Raluca; Barwick, Melanie; Zlotkin, Stanley

    2017-05-22

    Leading children's hospitals in high-income settings have become heavily engaged in international child health research and educational activities. These programs aim to provide benefit to the institutions, children and families in the overseas locations where they are implemented. Few studies have measured the actual reciprocal value of this work for the home institutions and for individual staff who participate in these overseas activities. Our objective was to estimate the perceived reciprocal value of health professionals' participation in global child health-related work. Benefits were measured in the form of skills, knowledge and attitude strengthening as estimated by an adapted Global Health Competency Model. A survey questionnaire was developed following a comprehensive review of literature and key competency models. It was distributed to all health professionals at the Hospital for Sick Children with prior international work experience (n = 478). One hundred fifty six health professionals completed the survey (34%). A score of 0 represented negligible value gained and a score of 100 indicated significant capacity improvement. The mean respondent improvement score was 57 (95% CI 53-62) suggesting improved overall competency resulting from their international experiences. Mean scores were >50% in 8 of 10 domains. Overall scores suggest that international work brought value to the hospital and over half responded that their international experience would influence their decision to stay on at the hospital. The findings offer tangible examples of how global child health work conducted outside of one's home institution impacts staff and health systems locally.

  19. Global Reduction in HIV-related Maternal Mortality: ART as a Key Strategy

    Hamisu M. Salihu, MD, PhD

    2015-12-01

    Full Text Available Dr. Holtz and colleagues present a synthesis of evidence from published studies over the previous decade on the collective impact of HIV-targeted interventions on maternal mortality. Amongst an assortment of interventions [that include antiretroviral therapy (ART, micronutrients (multivitamins, vitamin A and selenium, and antibiotics], only ART reduced maternal mortality among HIV-infected pregnant and post-partum mothers. These findings have fundamental and global strategic implications. They are also timely since they provide the evidence that ART reduces HIV-related maternal mortality, and by further enhancing access to ART in HIV-challenged and poor regions of the world, significant improvement in maternal morbidity and mortality indices could be attained. The paper bears good tidings and sound scientific proof that the financial investment made globally by government and non-governmental organizations and agencies to reduce the global burden of HIV/AIDS primarily by making ART more accessible to regions of the world most affected by the epidemic is beginning to show beneficial effects not only in terms of numerical reductions in the rates of new cases of HIV/AIDS among women, but also in maternal mortality levels.

  2. Relation of major volcanic center concentration on Venus to global tectonic patterns

    Crumpler, L. S.; Head, James W.; Aubele, Jayne C.

    1993-01-01

    Global analysis of Magellan image data indicates that a major concentration of volcanic centers covering about 40 percent of the surface of Venus occurs between the Beta, Atla, and Themis regions. Associated with this enhanced concentration are geological characteristics commonly interpreted as rifting and mantle upwelling. Interconnected low plains in an annulus around this concentration are characterized by crustal shortening and infrequent volcanic centers that may represent sites of mantle return flow and net downwelling. Together, these observations suggest the existence of relatively simple, large-scale patterns of mantle circulation similar to those associated with concentrations of intraplate volcanism on earth.

  4. Global Risks as Factors that Affect the Current system of international Relations

    Irina A. Zaitseva

    2017-01-01

    Full Text Available The problem of the globalization of risks is examined in this article. Based on the World Economic Forum (WEF report on global risks 2015-2017, the impact of global risks on the social and economic development of countries is examined. Economic, social, environmental, geopolitical, technological risks are analyzed in a coordinated fashion. The article notes that the main risks are in the field of environment and ecology. Anthropogenic pressure amplification, scientific and technological advance have an influence on the natural environment. The risks of infrastructure and environmental damage in danger zone are increased because of the growth of the frequency of extreme weather events. The measures for the protection of the environment are examined. The unilateral approach to solving international issues, instead of the collective efforts of the international community; the deployment of weapons of mass destruction (nuclear, chemical, biological and technologies for the production of radioactive materials; escalation of economic and resource nationalization (the desire of States to expropriate or restrict the export of important for the world economy of resources, etc. promote the increasing geopolitical risks.Economic risks include the risk in terms of their likelihood their impact on the macroeconomic, as from the financial systems and infrastructure to price volatility and regulatory issues. Social risks are the risks relating to instability of population dynamics, social crises and human survival.Technological risks include such problems as software defects, failure of important information systems, upon which today industrial production is depended, the services and communications sector; the escalation of large-scale cyber-attacks; theft of electronic information and the illegal usage of personal data. The trends that can intensify the global risks or to change the correlation between them are analyzed in this article.

  5. Dynamic modelling of water demand, water availability and adaptation strategies for power plants to global change

    Koch, Hagen; Voegele, Stefan

    2009-01-01

    According to the latest IPCC reports, the frequency of hot and dry periods will increase in many regions of the world in the future. For power plant operators, the increasing possibility of water shortages is an important challenge that they have to face. Shortages of electricity due to water shortages could have an influence on industries as well as on private households. Climate change impact analyses must analyse the climate effects on power plants and possible adaptation strategies for the power generation sector. Power plants have lifetimes of several decades. Their water demand changes with climate parameters in the short- and medium-term. In the long-term, the water demand will change as old units are phased out and new generating units appear in their place. In this paper, we describe the integration of functions for the calculation of the water demand of power plants into a water resources management model. Also included are both short-term reactive and long-term planned adaptation. This integration allows us to simulate the interconnection between the water demand of power plants and water resources management, i.e. water availability. Economic evaluation functions for water shortages are also integrated into the water resources management model. This coupled model enables us to analyse scenarios of socio-economic and climate change, as well as the effects of water management actions. (author)

  13. Space matters: the relational power of mobile technologies

    Nancy Odendaal

    2014-01-01

    Full Text Available The ubiquitous presence of mobile telephony and proliferation of digital networks imply a critical role for these technologies in overcoming the constraints of space in fragmented cities. Academic literature draws from a range of disciplines but fails to address the significance of new technologies for African and South African cities. Debates on technologies and urban spaces reflect a Northern bias and case literature that dwells on the developmental aspects of ICT do not engage with the broader significance with regards to urban change in African cities. This research addresses these gaps by examining the local transformative qualities of mobile telephony in a South African city, Durban. It focuses on the ways in which informal traders active in the city use technology. Actor-network theory was used in the analysis of the field work, uncovering material and human actors, network stabilization processes and agency in determining the transformative potential of this form of digital networking at city and local scales. Findings indicate that appropriation of technology is informed by livelihood strategies. Innovation is enabled when translation extends to appropriation. More in-depth research is needed on how technology is molded and appropriated to suit livelihoods. Throughout the research the spatial dimensions of the relationship between mobile telephony and networks were considered. The network spaces that emerge from actor relations do not correspond with the physical spaces usually considered in policy.

  14. Gamma power and cognition in patients with schizophrenia and their first-degree relatives.

    Díez, Álvaro; Suazo, Vanessa; Casado, Pilar; Martín-Loeches, Manuel; Molina, Vicente

    2014-01-01

    Gamma oscillations are essential for functional neural assembly formation underlying higher cerebral functions. Previous studies concerning gamma band power in schizophrenia have yielded diverse results. In this study, we assessed gamma band power in minimally treated patients with schizophrenia, their first-degree relatives and healthy controls during an oddball paradigm performance, as well as the relation between gamma power and cognitive performance. We found a higher gamma power in the patient group than in the healthy controls at the P3, P4, Fz, Pz and T5 sites. Compared with their relatives, gamma power in the patients was only marginally higher over P3 and P4. We found a nearly significant inverse association between gamma power at F4 and Tower of London performance in the patients, as well as a significant inverse association between gamma power at T5 and verbal memory and working memory scores in the relatives. These results support higher total gamma power in association with schizophrenia and its inverse association with cognitive performance in patients and their first-degree relatives.

  15. Power and trust in organizational relations: an empirical study in Turkish public hospitals.

    Bozaykut, Tuba; Gurbuz, F Gulruh

    2015-01-01

    Given the salience of the interplay between trust and power relations in organizational settings, this paper examines the perceptions of social power and its effects on trust in supervisors within the context of public hospitals. Following the theoretical background from which the study model is developed, the recent situation of hospitals within Turkish healthcare system is discussed to further elucidate the working conditions of physicians. Sample data were collected employing a structured questionnaire that was distributed to physicians working at seven different public hospitals. The statistical analyses indicate that perceptions of supervisors' social power affect subordinates' trust in supervisors. Although coercive power is found to have the greatest impact on trust in supervisors, the influence of the power base is weak. In addition, the results show that perceptions of social power differ between genders. However, the results do not support any of the hypotheses regarding the relations between trust in supervisors and the examined demographic variables. Copyright © 2014 John Wiley & Sons, Ltd.

    present data on the overnight costs of more than half of nuclear reactors built worldwide since the beginning of the nuclear age. The authors claim that this consolidated data set offers more accurate insights than previous country-level assessments. Unfortunately, the authors make analytical choices that mask nuclear power's real construction costs, cherry pick data, and include misleading data on early experimental and demonstration reactors. For those reasons, serious students of such issues should look elsewhere for guidance about understanding the true costs of nuclear power. - Highlights: • claim to accurately assess nuclear plant costs over time. • The authors err by relying on overnight costs, which exclude interest. • The authors cherry pick data (e.g, ignoring problems with French nuclear data). • The article's cherry picked data don’t even support the article's own conclusions. • Lovering et al. is not a reliable source for costs of nuclear power.

  20. Relative motions of the Australian, Pacific and Antarctic plates estimated by the Global Positioning System

    Larson, Kristine M.; Freymueller, Jeff

    1995-01-01

    Global Positioning System (GPS) measurements spanning approximately 3 years have been used to determine velocities for 7 sites on the Australian, Pacific and Antarctic plates. The site velocities agree with both plate model predictions and other space geodetic techniques. We find no evidence for internal deformation of the interior of the Australian plate. Wellington, New Zealand, located in the Australian-Pacific plate boundary zone, moves 20 +/- 5 mm/yr west-southwest relative to the Australian plate. Its velocity lies midway between the predicted velocities of the two plates. Relative Euler vectors for the Australia-Antarctica and Pacific-Antarctica plates agree within one standard deviation with the NUVEL-1A predictions.

  1. Global environmental issues and electric power in the twenty-first century

    Hidy, G.M.; Spencer, D.F.

    1993-01-01

    Development of the electric utility industry in the 21st Century will be central to the well-being of mankind. Electricity worldwide is still likely to be produced mainly from fossil fuel combustion for the foreseeable future. On a global scale, this energy sector will contribute to growing carbon dioxide (CO 2 ) emissions through most of the next century. A potential for global climate alteration has been identified with accumulation of CO 2 and other greenhouse gases (GHGs) in the Earth's atmosphere. If climate changes, adverse environmental effects are possible, acting on human systems, as well as on managed and natural ecosystems. Projected rates of increase in atmospheric CO 2 levels for the next century have motivated decision makers to consider early strategies for beginning to aggressively manage GHG emissions. The objective of this paper is to review the global issues associated with expected increases in gaseous emissions, particularly carbon dioxide from increased energy use, indicating the nature and significance of the issue. The authors emphasize a methodology integrating information on environmental issues with social and economic factors to develop informed international policies. The paper summarizes the technological choices available worldwide that could minimize the environmental impact of increasing energy use, particularly with respect to enhanced electricity production

  2. Life cycle analysis of distributed concentrating solar combined heat and power: economics, global warming potential and water

    Norwood, Zack; Kammen, Daniel

    2012-12-01

    We report on life cycle assessment (LCA) of the economics, global warming potential and water (both for desalination and water use in operation) for a distributed concentrating solar combined heat and power (DCS-CHP) system. Detailed simulation of system performance across 1020 sites in the US combined with a sensible cost allocation scheme informs this LCA. We forecast a levelized cost of 0.25 kWh-1 electricity and 0.03 kWh-1 thermal, for a system with a life cycle global warming potential of ˜80 gCO2eq kWh-1 of electricity and ˜10 gCO2eq kWh-1 thermal, sited in Oakland, California. On the basis of the economics shown for air cooling, and the fact that any combined heat and power system reduces the need for cooling while at the same time boosting the overall solar efficiency of the system, DCS-CHP compares favorably to other electric power generation systems in terms of minimization of water use in the maintenance and operation of the plant. The outlook for water desalination coupled with distributed concentrating solar combined heat and power is less favorable. At a projected cost of 1.40 m-3, water desalination with DCS-CHP would be economical and practical only in areas where water is very scarce or moderately expensive, primarily available through the informal sector, and where contaminated or salt water is easily available as feed-water. It is also interesting to note that 0.40-1.90 m-3 is the range of water prices in the developed world, so DCS-CHP desalination systems could also be an economical solution there under some conditions.

    2017-03-01

    Full Text Available Energy consumption in cellular networks is receiving significant attention from academia and the industry due to its significant potential economic and ecological influence. Energy efficiency and renewable energy are the main pillars of sustainability and environmental compatibility. Technological advancements and cost reduction for photovoltaics are making cellular base stations (BSs; a key source of energy consumption in cellular networks powered by solar energy sources a long-term promising solution for the mobile cellular network industry. This paper addresses issues of deployment and operation of two solar-powered global system for mobile communications (GSM BSs that are being deployed at present (GSM BS 2/2/2 and GSM BS 4/4/4. The study is based on the characteristics of South Korean solar radiation exposure. The optimum criteria as well as economic and technical feasibility for various BSs are analyzed using a hybrid optimization model for electric renewables. In addition, initial capital, replacement, operations, maintenance, and total net present costs for various solar-powered BSs are discussed. Furthermore, the economic feasibility of the proposed solar system is compared with conventional energy sources in urban and remote areas.

  5. Long-term outlook for global natural uranium and uranium enrichment supply and demand situations after the impact of Fukushima Daiichi Nuclear Power Plant accident

    Matsuo, Yuhji; Murakami, Tomoko

    2012-01-01

    In this paper, the authors propose long-term projections of global nuclear power generation, uranium production, and uranium enrichment capacities by region, and estimate the trade flows of natural uranium and uranium enrichment activities in 2020 and 2035. In spite of the rapid nuclear power generation capacity growth expected especially in Asia, the natural uranium and uranium enrichment trade will not be tightened by 2020 due to the projected increase in both natural uranium production and uranium enrichment capacities, which may cause a drop in natural uranium and uranium enrichment prices. Thus, there is a great possibility that the current projects for capacity expansion will be delayed considerably. However, in the 'high-demand scenario', where nuclear expansion will be accelerated due to growing concerns about global warming and energy security issues, additional investments in uranium production and enrichment facilities will be needed by 2035. In Asia, the self-sufficiency ratio for both natural uranium supply and uranium enrichment activities will remain relatively low until 2035. However, the Herfindahl-Hirschman (HH) index of natural uranium and uranium enrichment activity trade to Asia will be lowered considerably up to 2035, indicating that nuclear capacity expansion can contribute to enhancing energy security in Asia.

  7. Smart Global Maximum Power Point Tracking Controller of Photovoltaic Module Arrays

    Long-Yi Chang

    2018-03-01

    Full Text Available This study first explored the effect of shading on the output characteristics of modules in a photovoltaic module array. Next, a modified particle swarm optimization (PSO method was employed to track the maximum power point of the multiple-peak characteristic curve of the array. Through the optimization method, the weighting value and cognition learning factor decreased with an increasing number of iterations, whereas the social learning factor increased, thereby enhancing the tracking capability of a maximum power point tracker. In addition, the weighting value was slightly modified on the basis of the changes in the slope and power of the characteristic curve to increase the tracking speed and stability of the tracker. Finally, a PIC18F8720 microcontroller was coordinated with peripheral hardware circuits to realize the proposed PSO method, which was then adopted to track the maximum power point of the power–voltage (P–V output characteristic curve of the photovoltaic module array under shading. Subsequently, tests were conducted to verify that the modified PSO method exhibited favorable tracking speed and accuracy.

  9. Power Deals. Mergers and acquisitions activity within the global electricity and gas market. 2007 Annual Review

    2007-01-01

    The year 2007 saw a continued remarkable expansion in the total number and value of deals in the power utilities sector (electricity and gas) worldwide. A 25% increase put the total power deal value of USD 372.5bn nearly nine times above the US$43bn recorded just four years earlier in 2003. Records continue to be set in the sector for the total number and value of deals and for the size of individual deals. There was little sign of the sector pausing for breath in 2007. There were fewer mega-deals, reflecting the complexity of getting really huge deals over the political and regulatory hurdles, but this was more than compensated by a rise in mid-size deal numbers. There was no clear evidence of a fall-off in deal activity in the second half of the year as the credit crisis broke. Indeed, 57% of all power sector deals, 441 of the total 768 deals, came in the second half. Strong deal momentum characterised all the major markets and, with the restructuring of the Russian electricity sector, 2007 marked the year when deals in the Russian Federation made a significant impact on the worldwide totals. Thus, for the first time, Power Deals 2007 includes a specific section on the Russian deals and we separate them out from the wider Asia Pacific totals where they featured in previous editions

    1997-01-01

    The 30 years of the exploitation of the TPP Rance in France and Kyslogubskaya TPP in Russia had proved the energy expedience economical and ecological effectiveness and a high performance of the tidal energy. The possibility of such utilizing could be proved thanks to the application of the theoretical cycles of Gibrat, of the bulb units and the russian model of the tidal utilizing and application of the floating methods of creating the TPP. The investigations at TPP Kislaya Guba helped to solve the row of problems of marine power building with the high exploitation performance and ecological safety. Thus the TPP of Mezen with a capacity of 17 million kW can transfer to the united power system of Europe 50 TWh/year and the Tugur TPP with a capacity 8 million kW can produce 20 TWh/year of energy for the power system of seaside of Russian and Japan. Penzinskaya TPP with the capacity of 87 million kW can be promoted in 21. century in connection to the advanced in USA proposition of construction of the combining transport-power tunnel across the Bering Strait.

  14. Nature–Culture Relations: Early Globalization, Climate Changes, and System Crisis

    Sing C. Chew

    2016-01-01

    Full Text Available Globalization has been on everyone’s lips in light of the contemporary conditions. It has been viewed mostly as a stage reached as a result of long-term societal changes over the course of world history. For us, globalization has been an ongoing process for at least the last 5000 years. Little attention has been paid to the socioeconomic and natural processes that led to the current transformation. With the exception of historical sociologists, there is less interest in examining the long-term past as it is often assumed that the past has nothing to teach us, and it is the future that we have to turn our intellectual gaze. This paper will argue the opposite. We believe a long-term tracing of the socioeconomic and political processes of the making of the modern world will allow us to have a more incisive understanding of the current trajectory of world development and transformations. To plead our case, we outline the emergence of the first Eurasian World Economy linking seven regions (Europe, the Arabian Peninsula, East Africa, the Persian Gulf, Central Asia, South Asia, Ceylon, Southeast Asia, and China of the world, with the exception of the Americas, starting as early as 200 BC, and the sequence of structural crises and transformations (trading networks and commodities that has circumscribed the structures and trends of the current global system. Such consideration in our view is limited if we do not also include the relations between social systems and Nature, and the rhythms of the climate. For the latter, an awareness of the natural rhythms of the climate as well as human induced changes or climate forcing have triggered system-wide level collapses during certain early historical periods.

    2014-11-01

    Full Text Available This study focuses on worldwide governance. It will be related to the Assian approach of international relationships. This approach claiming by the Chinese is closed to the David Miller Nationalist and liberal way of thinking. But it remains very restrictive because it is only based on the liberal economic point of view. We will do a critical study of the principles which are regulating the governances and we will analyse a special sectorial field: the Sino-African relations. These thoughts and statements need to have a sectorial dimension of approaching matters. The management of the different governments can have effects on local realities of people's life and on investments. In thirty years China passed from an emerging country to the second worldwide economically powerful country just behind the United States. Now, they must have an interdependance relationship with the United States. It is very important and necessary to undermine this interdependance relationship in order to understand how its economic strategy has an influence upon the worldwide market. And from this study, we will understand how the Chinese relate to the balance of power they are dealing with.

All these operators map binary relations to binary relations. We compare the ex...

  1. Increasing water cycle extremes in California and in relation to ENSO cycle under global warming

    Yoon, Jin-Ho; Wang, S-Y Simon; Gillies, Robert R.; Kravitz, Ben; Hipps, Lawrence; Rasch, Philip J.

    2015-01-01

    Since the winter of 2013–2014, California has experienced its most severe drought in recorded history, causing statewide water stress, severe economic loss and an extraordinary increase in wildfires. Identifying the effects of global warming on regional water cycle extremes, such as the ongoing drought in California, remains a challenge. Here we analyse large-ensemble and multi-model simulations that project the future of water cycle extremes in California as well as to understand those associations that pertain to changing climate oscillations under global warming. Both intense drought and excessive flooding are projected to increase by at least 50% towards the end of the twenty-first century; this projected increase in water cycle extremes is associated with a strengthened relation to El Niño and the Southern Oscillation (ENSO)—in particular, extreme El Niño and La Niña events that modulate California's climate not only through its warm and cold phases but also its precursor patterns.

    2014-07-01

    Full Text Available Brugha and Bruen (2014 raise a number of compelling issues related to the interaction between politics and policy in the global health context. The first question that their views invite is whether this is, at heart, best characterized as a benign or malign influence. Many commentators have suggested that this overlap should be discouraged (see, for example, Marseille et al 2002; Thomas & Weber 2004; Fidler 2011, while others advocate a decrease in 'stove-piped' or 'siloed' approaches to government, politics, and academia (Lee et al 2010; Feldbaum 2011. To use a parallel example, the world of sport has indirectly contributed a number of notable political advances, not least the end of apartheid in South Africa as a partial result of the ban imposed on their international teams (Nixon 2002. In spite of this, organizations such as FIFA refuse to be drawn into sanctioning international football teams on non-sporting grounds (Sobolev & Gazeta 2014. The future scope and role of global health will, inevitably, face corresponding challenges.

  3. Global environmental policy strategies. ''Environment and development'' in north-south relations

    Bruckmeier, K.

    1994-01-01

    Global environmental policy has hardly made headway after the United Nations World Conference on Environment and Development (UNCED) in Rio in June 1992, despite there being no shortage of programmes, institutions, and actors. Obviously, formal structures for political action based on the system of institutions of the United Nations do not suffice. Global environmental policy strategies must reach further, overcoming system-immanent obstacles to sustainable development. This necessitates analyzing the causes of environmental destruction and making a critical evaluation of the relations between the societies of the North and South that received their imprint from development policies. Only after such a preliminary elucidation by interdisciplinary approaches in the light of political and ecological economy and human ecology does an empirical analysis of politically controlled processes in environmental and development policy make sense. The analysis points to strategies for this international political field that rely on non-governmental actors and social movements, and question the traditional European model of an environmental policy determined by government institutions.

  5. Prospects and strategies for nuclear power: global boon or dangerous diversion?

    Beck, P.

    1994-01-01

    The complex arguments surrounding the future of nuclear energy are examined. The probability of growth in electricity demand in the next century and the possibility of climate change due to the greenhouse effect support the retention of nuclear energy as an option for strong world-wide expansion. Three important concerns are associated with present nuclear technology, however, which makes expansion politically unlikely. These are the possibility of accidental radioactive releases, safe disposal of long-lived waste and the risk of proliferation of nuclear weapons and terrorism that might accompany an expansion of nuclear power. Furthermore, as competition increases in the power generation market, it is unlikely that private investment in nuclear power will be forthcoming without government support. Technological developments over the past decade have demonstrated new ways of improving the safety and security of fuel cycles by reducing the waste disposal problem and proliferation damages, and simpler, safer reactor designs have emerged. There are, nevertheless grave doubts as to whether funds will be found to bring a new generation of reactors to the stage where they are commercially available. A far greater understanding of, and consensus about, whether the new developments could lead to a safe, economic and acceptable nuclear industry is needed. (UK)

  6. Climate change and the role of nuclear power - contributions to a global solution

    McKechnie, A.J.

    1990-01-01

    The threat of global climate change is a challenge to those who decide on energy policy. If we are complacent and the worst case scenario materializes, our descendants could be faced with unprecedented problems that would impose massive costs. On the other hand, it is our generation which would suffer if substantial resources were devoted to addressing a problem that did not turn out to be serious. Fortunately, the choice is not a stark as this. There are options such as increased energy efficiency and clean fuels that are economically justified before their environmental benefits are considered. These options are the first priority for addressing climate change. What will be the contribution of nuclear energy? In developing countries it is likely to be small. In the industrialized world, where the cost of capital is lower, the role of nuclear will depend on construction and operating performance of the industry, and the level of public confidence. New nuclear technologies that are inherently safe and small modular designs could transform the nuclear option if costs are competitive with other energy sources. The nuclear option is one that should be kept alive in case a global environmental crisis is forced upon us. (orig.)

  7. Review of the total system related to operation of nuclear-powered ship

    Takamasa, Tomoji; Miyashita, Kunio

    2000-01-01

    It is essential to establish a marine reactor having excellent safety and reliability, which is capable of competing economically with conventional ships, and which can be accepted by international society, in order to be prepared for practical application of future nuclear-powered ships. For this purpose, it is important not only to demonstrate a marine reactor using a model or test device to simulate actual operation, but also to establish the environmental requirements for operation of a nuclear-powered ship, such as safety standards that are operationally and internationally common for ships, and to establish a repair base for nuclear-powered ships. Systems research for the practical application of nuclear-powered ships was conducted for five years, fiscal years 1992 through 1996, by a group in the Japan Atomic Energy Research Institute (JAERI), under the project title 'Review of the total system related to operation of nuclear-powered ships.' The project sought to summarize requirements for the practical application of nuclear-powered ships from the standpoint of the need side, e.g., what nuclear-powered ships will be requested, and what functions will be provided under the expected future social environment; to show a complete system concept for the operation of nuclear-powered ships; and to clarify the situations creating demand for nuclear-powered ships, as well as the system and environmental conditions to be established for operation of practical nuclear-powered ships. Study considerations included the size of the operation system for a nuclear-powered ship, a scenario for introducing a nuclear-powered container ship, and economic evolution from the effects on the whole shipping system, based on container ships, of introducing a nuclear-powered ship. The results of these considerations were made the framework for constructing an entire system and evaluating its economy. The treatment and disposal of radioactive waste from a nuclear-powered ship, and the

  8. A mathematical model for malaria transmission relating global warming and local socioeconomic conditions

    Hyun M Yang

    2001-06-01

    Full Text Available OBJECTIVE: Sensitivity analysis was applied to a mathematical model describing malaria transmission relating global warming and local socioeconomic conditions. METHODS: A previous compartment model was proposed to describe the overall transmission of malaria. This model was built up on several parameters and the prevalence of malaria in a community was characterized by the values assigned to them. To assess the control efforts, the model parameters can vary on broad intervals. RESULTS: By performing the sensitivity analysis on equilibrium points, which represent the level of malaria infection in a community, the different possible scenarios are obtained when the parameters are changed. CONCLUSIONS: Depending on malaria risk, the efforts to control its transmission can be guided by a subset of parameters used in the mathematical model.

  9. Decision-making interventions to stop the global atrial fibrillation-related stroke tsunami.

    Cerasuolo, Joshua O; Montero-Odasso, Manuel; Ibañez, Agustin; Doocy, Shannon; Lip, Gregory Yh; Sposato, Luciano A

    2017-04-01

    Atrial fibrillation affects 33.5 million people worldwide and its prevalence is expected to double by 2050 because of the aging population. Atrial fibrillation confers a 5-fold higher risk of ischemic stroke compared to sinus rhythm. We present our view of the role of shared medical decision-making to combat global underutilization of oral anticoagulation for stroke prevention in atrial fibrillation patients. Oral anticoagulation underuse is widespread as it is present within atrial fibrillation patients of all risk strata and in countries across all income levels. Reasons for oral anticoagulation underuse include but are probably not limited to poor risk stratification, over-interpretation of contraindications, and discordance between physician prescription preferences and actual administration. By comparing a catastrophic event to the consequences of atrial fibrillation related strokes, it may help physicians and patients understand the negative outcomes associated with oral anticoagulation under-utilization and the magnitude to which oral anticoagulations neutralize atrial fibrillation burden.

  10. Neo-Mercantilist Policy and China’s Rise as a Global Power

    Fu-Lai Tony Yu

    2017-12-01

    Full Text Available This paper argues that China is adopting Neo-mercantilist policies in its national development and global expansion. China’s Neo-mercantilist strategies include promoting nationalism and patriotism, stockpiling gold and foreign reserves, striving for favorable balance of payment via exchange rate manipulation, tariff, export subsidies and other trade protections. The Chinese government also controls population growth for national development and social control, initiates “Belt and Road” project and the Asian Infrastructure Investment Bank to counter American and Western influences, and deploys strategic expansion in Africa, South Asia and Latin American countries. China’s economic success through Neo-mercantilist strategies may provide an incentive for other Asian developing nations such as the Philippines to follow.

    2015-03-01

    Full Text Available The process of globalization influences not only economic relations but also causes significant changes in the area of industrial relations and employee participation. The answer to the challenges of globalization has been the emergence of new transnational institutions of participation in the form of European Works Councils (EWCs and European Companies (SEs and the concluding of transnational company agreements. The aim of this paper is to examine the impact of globalization on the development of employee participation in Polish industrial relations. The paper argues that globalization leads to dissemination of forms of employee participation in Polish companies but the scope of the forms of participation is still lower than in companies in the old EU countries. The slow growth of participation in Poland has primarily resulted from an indifferent or even hostile attitude to participation on the part of the state and social partners.

  13. Reconceptualizing the nature and health consequences of work-related insecurity for the new economy: the decline of workers' power in the flexibility regime.

    Scott, Heather K

    2004-01-01

    This article aims to reconceptualize job insecurity in a manner relevant to shifts in the power relations of work that have accompanied globalization, in order to assess the implications for workers' health. The linkage between job insecurity and health has been well established, but little formal theorizing has analyzed the mechanisms responsible. Implicitly, however, the assumption remains that its role as a stressor is limited to the realm of job strain, whereby workers lack control over a threatened employment situation. Within this framework, job insecurity and related dimensions of power remain locked in the "box" of the standard employment relationship, precluding an analysis of work-related insecurity in the new context of globalization. In contrast, the author constructs a model of work-related insecurity that takes into account current shifts in the balance of power toward employers, which in turn has undermined the fundamental quid pro quo associated with the standard postwar model of employment. She proposes that job insecurity is no longer a mere temporary break in an otherwise predictable work-life pattern but rather a structural feature of the new labor market. Emerging contingencies associated with the New Economy, "flexibilized" employment relationships, and diminution of workers' power have constituted work-related insecurity as a chronic stressor with several implications for long-term health outcomes at the individual and societal levels.

    Full Text Available The paper presents the analysis of South Africa’s BRICS Presidency which formally started with the summit in Durban on March 15-17, 2013 and finished in June 2014 with the BRICS leaders’ Fortaleza meeting. To assess the Presidency effectiveness the author applies “supply-demand” model fine-tuned to achieve a balance of external conditions and national priorities of the country chairing informal summitry institutions, such as BRICS, G20 or G7/8. This analytical paradigm allows reveal to what extent the Presidency has managed to ensure: 1 a high level of response to the key global governance challenges in the summit agenda and decisions; 2 a balance between internal demand (domestic priorities and external demand (other members’ interests and global governance challenges in the Presidency priorities; 3 maximal use of the institution’s capabilities. Conformity of the role chosen by the Presidency (organizer, mediator, political leader, national representative to the combination of external and internal conditions is also considered as it is a major factor of the presidency success. Content analysis, comparative analysis and functional approach were used in the study. The primary sources of the research included the BRICS documents, national documents of the member states, the leaders’ addresses. The study reveals that the major factors of the South African BRICS presidency success were commitment to implementation of the Durban decisions and action plan as well as the will to utilize the BRICS capabilities for African countries development and South African regional leadership. In the former case the foundation of success was reinforced the chair’ choice of the organizer role, whereas in the latter a combination of the political leader and national representative roles proved to be the most productive for the presidency.

  15. Traffic-related air pollution and allergic disease: an update in the context of global urbanization.

    Carlsten, Christopher; Rider, Christopher F

    2017-04-01

    The review aims to give an update on the literature around traffic-related air pollution (TRAP) and allergic disease in the context of global urbanization, as the most populous countries in the world face severe TRAP exposure challenges. As research continues to show that gene-environment interactions and epigenetics contribute to the TRAP-allergy link, evidence around the links to climate change grows. Greenspace may provide a buffer to adverse effects of traffic on health, overall, but pose risks in terms of allergic disease. The link between traffic-related pollution and allergy continues to strengthen, in terms of supportive observational findings and mechanistic studies. Levels of TRAP across the world, particularly in Asia, continue to dramatically exceed acceptable levels, suggesting that the related adverse health consequences will accelerate. This could be counterbalanced by primary emission control and urban planning. Attention to combined effects of TRAP and allergen exposure is critical to avoiding misleading inferences drawn though examination only of isolated factors.

  16. The MUSIC of galaxy clusters - II. X-ray global properties and scaling relations

    Biffi, V.; Sembolini, F.; De Petris, M.; Valdarnini, R.; Yepes, G.; Gottlöber, S.

    2014-03-01

    We present the X-ray properties and scaling relations of a large sample of clusters extracted from the Marenostrum MUltidark SImulations of galaxy Clusters (MUSIC) data set. We focus on a sub-sample of 179 clusters at redshift z ˜ 0.11, with 3.2 × 1014 h-1 M⊙ mass. We employed the X-ray photon simulator PHOX to obtain synthetic Chandra observations and derive observable-like global properties of the intracluster medium (ICM), as X-ray temperature (TX) and luminosity (LX). TX is found to slightly underestimate the true mass-weighted temperature, although tracing fairly well the cluster total mass. We also study the effects of TX on scaling relations with cluster intrinsic properties: total (M500 and gas Mg,500 mass; integrated Compton parameter (YSZ) of the Sunyaev-Zel'dovich (SZ) thermal effect; YX = Mg,500 TX. We confirm that YX is a very good mass proxy, with a scatter on M500-YX and YSZ-YX lower than 5 per cent. The study of scaling relations among X-ray, intrinsic and SZ properties indicates that simulated MUSIC clusters reasonably resemble the self-similar prediction, especially for correlations involving TX. The observational approach also allows for a more direct comparison with real clusters, from which we find deviations mainly due to the physical description of the ICM, affecting TX and, particularly, LX.

  17. Global Maximum Power Point Tracking (MPPT of a Photovoltaic Module Array Constructed through Improved Teaching-Learning-Based Optimization

    Kuei-Hsiang Chao

    2016-11-01

    Full Text Available The present study proposes a maximum power point tracking (MPPT method in which improved teaching-learning-based optimization (I-TLBO is applied to perform global MPPT of photovoltaic (PV module arrays under dissimilar shading situations to ensure the maximum power output of the module arrays. The proposed I-TLBO enables the automatic adjustment of teaching factors according to the self-learning ability of students. Incorporating smart-tracking and self-study strategies can effectively improve the tracking response speed and steady-state tracking performance. To evaluate the feasibility of the proposed I-TLBO, a HIP-2717 PV module array from Sanyo Electric was employed to compose various arrays with different serial and parallel configurations. The arrays were operated under different shading conditions to test the MPPT with double, triple, or quadruple peaks of power-voltage characteristic curves. Boost converters were employed with TMS320F2808 digital signal processors to test the proposed MPPT method. Empirical results confirm that the proposed method exhibits more favorable dynamic and static-state response tracking performance compared with that of conventional TLBO.

    Water temperatures and water availability can affect the reliable operations of power plants in the United States. Data on water-related impacts on the energy sector are not consolidated and are reported by multiple agencies. This study provides an overview of historical incidents where water resources have affected power plant operations, discusses the various data sources providing information, and creates a publicly available and open access database that contains consolidated information about water-related power plant curtailment and shut-down incidents. Power plants can be affected by water resources if incoming water temperatures are too high, water discharge temperatures are too high, or if there is not enough water available to operate. Changes in climate have the potential to exacerbate uncertainty over water resource availability and temperature. Power plant impacts from water resources include curtailment of generation, plant shut-downs, and requests for regulatory variances. In addition, many power plants have developed adaptation approaches to reducing the potential risks of water-related issues by investing in new technologies or developing and implementing plans to undertake during droughts or heatwaves. This study identifies 42 incidents of water-related power plant issues from 2000-2015, drawing from a variety of different datasets. These incidents occur throughout the U.S., and affect coal and nuclear plants that use once-through, recirculating, and pond cooling systems. In addition, water temperature violations reported to the Environmental Protection Agency are also considered, with 35 temperature violations noted from 2012-2015. In addition to providing some background information on incidents, this effort has also created an open access database on the Open Energy Information platform that contains information about water-related power plant issues that can be updated by users.

  2. Local Power -- Global Connections: linking the world to a sustainable future through decentralized energy technology

    Brent, Richard; Sweet, David

    2007-07-01

    Various international dynamics are converging to increase the attractiveness of decentralized energy as a complement to existing centralized energy infrastructures. Decentralized energy (DE) technologies, including onsite renewables, high efficiency cogeneration and industrial energy recycling, offer considerable benefits to those seeking working alternatives to emerging challenges in the energy sector. DE is ideally suited to provide clean affordable energy to areas where modern energy services are currently lacking. Having smaller generators close to where energy is required ensures a safe, reliable and secure energy supply when the energy is required. Furthermore, because DE is a much cleaner alternative than conventional central power plants and the energy provided comes at a much smaller price tag DE is an increasingly acceptable alternative both in the developed and developing world. DE is sure to play a key role in any plan to build a sustainable energy future. (auth)

  3. Relationship power, decision making, and sexual relations: an exploratory study with couples of Mexican origin.

    Harvey, S Marie; Beckman, Linda J; Browner, Carole H; Sherman, Christy A

    2002-11-01

    This study explored how couples of Mexican origin define power in intimate relationships, what makes men and women feel powerful in relationships, and the role of each partner in decision making about sexual and reproductive matters. Interviews were conducted with each partner of 39 sexually active couples and data were analyzed using content analysis. Results indicate that power is perceived as control over one s partner and the ability to make decisions. Women say they feel more powerful in relationships when they make unilateral decisions and have economic independence. Men feel powerful when they have control over their partner and bring home money. Respondents agreed that women make decisions about household matters and children, while men make decisions related to money. Findings indicate that whereas couples share decision making about sexual activities and contraceptive use, men are seen as initiators of sexual activity and women are more likely to suggest condom use.

  4. Economics of nuclear and thermal power plants in the transition to market relations

    Chernilin, Yu.F.

    1993-01-01

    In the economic conditions taking shape, the provision of electricity for the national economy of Russia, including in the short term (up to the years 2010-2015), depends in many ways on a weighted choice of strategy for the use of alternative means of electricity generation from the standpoint of fuel resources and electrical technology. When considering problems that need to be reassessed, the role of all alternative energy sources, including nuclear power, in the energy system of Russia must be determined, i.e., a strategy must be worked out for the development of the power industry. Information and data are presented on the present state of the electrical power industry in Russia including fossil and nuclear. Issues and policies associated with the transition to a market-driven economy as related to the nuclear power industry is examined. Specifically, a open-quotes Conception of a Power Policy for Russiaclose quotes is discussed

  5. SELF-DETERMINATION AND POWER: A HUMAN-CENTRIC APPROACH TO THE INTERNATIONAL RELATIONS

    Shameer Modongal

    2017-05-01

    Full Text Available This paper analyzes the importance of self-determination in international relations. It explains the puzzle why some small regions or group of people are ready to be small states by separating from big powerful states. The self-determination of a nation is preferable to the people than a military power of the large state. The military power of a state may not translate into a better life of people. So people’s empowerment cannot be treated the necessary outcome of state’s military power. When one group of people feel as marginalized in national policymaking and its implications, they show a secessionist tendency. This paper contends that people may prefer their ideology, identity and self-determination than the power of the state.

  7. Stress-related factors in the emergence of transient global amnesia with hippocampal lesion

    Juliane eDöhring

    2014-08-01

    Full Text Available The transient global amnesia (TGA is a rare amnesic syndrome that is characterized by an acute onset episode of an anterograde and retrograde amnesia. Its origin is still debated, but there is evidence for psychological factors involved in TGA. In neuroimaging, selective lesions in the CA1 fields of the hippocampus can be detected, a region that is particularly involved in the processing of memory, stress and emotion. The aim of this study was to assess the role of psychological stress in TGA by studying the prevalence of stress related precipitating events and individual stress-related personality profiles as well as coping strategies in patients. The hypothesis of a functional differentiation of the hippocampus in mnemonic and stress-related compartments was also evaluated. From all 113 patients, 18 % (n= 24 patients experienced emotional and psychological stress episodes directly before the TGA. In a cohort of 21 acute patients, TGA patients tend to cope with stress less efficiently and less constructively than controls. Patients who experienced a stress related precipitant event exhibited a higher level of anxiety in comparison to non-stress patients and controls. However, there was no difference between the general experience of stress and the number of stress inducing life events. The majority of patients (73% did show typical MRI lesions in the CA1 region of the hippocampal cornu ammonis. There was no clear association between stressful events, distribution of hippocampal CA1 lesions and behavioral patterns during the TGA. Disadvantageous coping strategies and an elevated anxiety level may increase the susceptibility to psychological stress which may facilitate the pathophysiological cascade in TGA. The findings suggest a role of emotional stress factors in the manifestation of TGA in a subgroup of patients. Stress may be one trigger involved in the emergence of transient lesions in the hippocampal CA1 region, which are thought to be the

  8. COMPETING CONCEPTIONS OF GLOBALIZATION

    Leslie Sklair

    2015-08-01

    Full Text Available Globalization is a relatively new idea in the social sciences, although people who work in and write about the mass media, transnational corporations and international business have been using it for some time. The purpose of this paper is to critically review the ways in which sociologists and other social scientists use ideas of globalization and to evaluate the fruitfulness of these competing conceptions. The central feature of the idea of globalization is that many contemporary problems cannot be adequately studied at the level of nation-states, that is, in terms of each country and its inter-national relations. Instead, they need to be conceptualized in terms of global processes. Some have even gone so far as to predict that global forces, by which they usually mean transnational corporations and other global economic institutions, global culture or globalizing belief systems/ideologies of various types, or a combination of all of these, are becoming so powerful that the continuing existence of the nation-state is in serious doubt. This is not a necessary consequence of most theories of globalization. The argument of this paper is that much of the globalization literature is confused because not all those who use the term distinguish it clearly enough from internation-alization, and some writers appear to use the two terms interchangeably. I argue that a clear distinction must be drawn between the inter-national and the global. The hyphen in inter-national is to distinguish (inadequate conceptions of the global' founded on the existing even if changing system of nation-states, from (genuine conceptions of the global based on the emergence of global processes and a global system of social relations not founded on national characteristics or nation-states. This global system theory is the framework for my own research. Globalization studies can be categorized on the basis of four research clusters:1. The world-systems approach; 2. The global

  9. An approach to safety problems relating to ageing of nuclear power plant components

    Conte, M.; Deletre, G.; Henry, J.Y.; Le Meur, M.

    1989-10-01

    The safety of nuclear power plants, in France, is discussed. The attention is focused on the ageing phenomena, as a potential cause of the degradation of the systems functional capabilities. The allowance for ageing in design and its importance on safety, are analyzed. The understanding of phenomena relating to ageing and the components surveillance, are considered. As the effective ageing on the components of nuclear power plants is not fully understood, technical improvements and more accurate analysis are required

    This standard presents guidelines for evaluating site-related geotechnical parameters for nuclear power sites. Aspects considered include geology, ground water, foundation engineering, and earthwork engineering. These guidelines identify the basic geotechnical parameters to be considered in site evaluation, and in the design, construction, and performance of foundations and earthwork aspects for nuclear power plants. Also included are tabulations of typical field and laboratory investigative methods useful in identifying geotechnical parameters. Those areas where interrelationships with other standards may exist are indicated

    1984-01-01

    Two representative examples were chosen to demonstrate that the problems related to safe working conditions can be solved with work being prepared extensively and in detail taking into consideration radiation protection and conventional job safety measures and with qualified staff. Most of the job safety problems in nuclear power plants are pretty much the same as in conventional plants. Despite successful implementation of employment and radiation protection in nuclear power plants, improvements in detail are possible and make sense. (orig.) [de

  14. THE ECONOMIC INSTRUMENTARY OF THE "SOFT POWER" IN THE INTERNATIONAL ECONOMIC RELATIONS

    Zlatka Kushelieva

    2017-09-01

    Full Text Available "Soft power" is a complex instrument of international politics. It is an organized set of interactions and relationships predetermined to a large extent by the psychological element. Its core qualities are attraction, persuasion and legitimacy. The "soft power" acts in international relations through a complex instrumentation consisting of actions in the military, political, economic, cultural, sports, ideological, religious spheres, but all its manifestations must be supported by the economic instrument. To this end, many countries have set up special bodies. It is expected that "soft power" will be a major instrument of international politics in the coming epoch.

  15. Public opinion on age-related degradation in nuclear power plants

    Matsuda, Toshihiro

    2005-01-01

    The first objective of this study is to shed light on the public opinion on age-related degradation at nuclear power plants, namely, on how the general public recognizes or views age-related degradation, which is a safety-related issue and one of the factors contributing to accidents and failures which occur at nuclear power plants. The second objective is to look into the impacts of the accident at Mihama Unit 3, which was caused by a failure to check on the piping wall thickness, on the public opinion on age-related degradation. The first survey was conducted in August 2003, followed by the second survey in October 2004, two months after the accident. The surveys found that the age-related degradation is being perceived by people as one of the risk factors that affect the safety of nuclear power plants. The characteristics of the citizens' perceptions toward age-related degradation in the form of piping cracks are that: (a) many respondents feel uneasy but a relatively few people consider that nuclear operators are technologically capable of coping with this problem; (b) many people believe that radioactivity may be released; and (c) numerous respondents consider that signs of cracks must be thoroughly detected through inspections, while on the other hand, a large percentage of the respondents attribute the accident to improper inspections/maintenance. Based on these results, the government and nuclear operators are expected to give most illuminating explanation on the current situation of and remedial measures against age-related degradation at nuclear power plants. As for the effects of the Mihama-3 accident on the public opinion on age-related degradation, it was revealed that the accident has not so significantly affected the general view for the safety of nuclear power plants, but has newly or strongly aroused people's consciousness of two of the risk factors - improper inspections/maintenance and the age-related degradation of piping.

  16. Powerful agent of change? The global insurance industry as a driver for greenhouse mitigation and adaptation

    Phelan, Liam; Taplin, Ros

    2007-01-01

    Full text: This paper explores the potential for the gloPal insurance industry to play a powerful and constructive role towards significant reductions in greenhouse gas emissions as well as in climate change adaptation. Climate change presents a formidable public policy challenge (IPCC 2001) and one to which sections of the insurance industry have been responsive (Mills 2005). The industry can be expected to play a further constructive role for three reasons: the industry has core capacities in risk management and loss prevention; the industry is the world's largest with annual income in the order of US$3.4 trillion derived from premiums and US$1 trillion derived from investments; and anthropogenic climate change is constricting limits to insurability, with implications for the ongoing functioning of the insurance sector (Mills and Lecomte 2006). Insurance understood as a social institution is both a crucial component of contemporary socio-economic systems and a powerful agent of socio-economic change (Pfeffer and Klock 1974, Denenberg et al. 1964). The ability to transfer risk historically has played a major facilitative role in economic and social development at the broadest scales of human socio-economic systems (Supple 1984; Clark 1999). Governments historically and currently explicitly harness the potential of insurance in support of specific public policy outcomes. The creation of the modern welfare state is a public policy objective on a grand scale achieved in part through application of insurance, in the form of universal health care and pensions (Lengwiler2003). The insurance industry itself also initiates significant socioeconomic change in three ways: direct engagement, for example by establishing the first fire brigades (Kline 1964a); loss prevention research, for example by conducting and financing research into building and vehicle safety (Mills and Lecomte 2006; Kline 1964b); and engaging in lobbying for implementation of safety standards (Kline

    Choudhury, B. J.

    1988-01-01

    Global observations at 37 GHz by the Nimbus-7 SMMR are related to zonal variations of land surface evaporation and primary productivity, as well as to temporal variations of atmospheric CO2 concentration. The temporal variation of CO2 concentration and the zonal variations of evaporation and primary productivity are shown to be highly correlated with the satellite sensor data. The potential usefulness of the 37-GHz data for global biospheric and climate studies is noted.

  18. Electric power generated by fossil fuels: Impact and environmental administration at global and local level

    Moscarella, John Paul

    1999-01-01

    An analysis is presented on the derived environmental implications of the current and future structure in the electric power market at international level. The reduced prices of the hydrocarbons determine that the fossil electricity is imposed on other generation forms, that which generates serious challenges to the companies and the governments as regards control and handling of gases emissions. By means of a comparative sample of eight electric companies of developed countries and in development, the tendencies are evaluated in the local and regional markets, as well as the environmental effects of different generating systems of electricity. The mechanism of well-known market is analyzed as activities implemented jointly (AIJ) referred to activities to be implemented jointly to combat the greenhouse gases effect. It concludes that in the short and medium term the conditions of the market will continue favoring the generation of fossil energy, reason why they should strengthen mechanisms of the climatic change control and to impel toward the long term the development of renewable and alternative energy

    Iliyasu, Z.; Abubakar, I.; Gajida, A.U.

    2010-07-01

    Sub-Saharan African countries are at an increased risk of the effects of global warming. Unfortunately they have the least capacity to adapt to its untoward effects. We studied public awareness of global warming, its perceived causes, effects and prevention in Kano city, northern Nigeria. Structured questionnaires were administered on a cross section of 181 adults in Kano eliciting their awareness of global warming, as well as perceived causes, effects and ways of prevention. Of the 181 respondents, 132 (72.9%) were aware of global warming mainly from electronic media (44.4%), the Internet (20.5%) and schools (18.7%). They mostly attributed it to air pollution (99.2%), use of fossil fuels (97.7%), toxic waste (78.0%) and chlorofluorocarbons (73.5%). Perceived effects of global warming include extremes of ambient temperature (97.7%), increased disease outbreaks (92.4%), floods (68.2%), droughts (51.5%) and loss of species (50.0%). Respondents opined that global warming could be prevented by using renewable sources of energy such as the sun (53.8%), massive tree planting (44.7%) and phasing out of old automobiles (43.2%). A significantly higher proportion of males, younger and educated respondents were aware of global warming. The high awareness about global warming needs to be reinforced through use of media to encourage advocacy and community action towards preventing global warming and ensuring environmental sustainability.
