    Conditions for wind power on a liberalised North European electrical power market are addressed in the paper. Results are presented from a recently completed study carried out by Risoe National Laboratory in collaboration with the Danish electric utilities Eltra, Elsam and Elkraft. A main result from the study is, that the market will be able to provide the necessary power regulation, that will be required year 2005 as consequence of the expected wind power capacity extension, according to the Danish energy plan, Energy21. The averege sales price on the market for the wind-generated electricity is less than the average spot market price, due to provision of power regulation to balance the unpredictability of the wind power. This reduction in the market value of wind power has been calculated to 10-20 DKK/MWh of 1.3-2.7 EUR/MWh. (au)

  2. Effects of internalising external production costs in a North European power market

    The aim of integrating national power markets is to improve the overall efficiency thereby making a potential for reducing electricity prices. However, efficiency is not necessarily improved if external environmental protection costs are neglected. In this paper, we analyse the effects of regulating an integrated power market by using environmental producer taxes based on external production costs. The analysis is based on an empirical equilibrium model for the North European power market. The results show that internalising costs will increase electricity producer prices by 40-50% in the period from 1995 to 2020. Further, demand for electricity will be reduced by 10%. We conclude, however, that in order to achieve the national Kyoto targets of reducing CO 2 emissions, further regulation is needed, such as national CO 2 taxes or cost efficient mechanisms like tradeable permits and joint implementation.

    A nearly continuous, 3600 km long, NE-running North European Transect (NET) is combined from the existing deep seismic reflection data sets in the Baltic Sea (BABEL, 1600 km), Northern Finland (FIRE 4-4A, 580 km) and Barents Sea (1-AR, 1440 km;). The reflective image of the deep crust is highly dependent on the thickness of the sedimentary cover. The cover is few hundred meters in the Baltic sea, few tens of meters in the land areas and few kilometers in the Barents Sea area. In the Barents Sea area, the seismic image is dominated by the layered structure of the sedimentary basins and the middle and lower crust are poorly imaged. Therefore the Moho boundary in the Barents Sea has been determined from wide-angle reflections. Geologically the transect covers the transition from Phanerozoic Europe to Precambrian Europe and back to the Phanerozoic Barents Sea Shelf. It displays how Northern Europe grew around Baltica in several tectonic episodes involving the formation and destruction of Columbia/Hudsonland, Rodinia and Pangea supercontinents. The paleo plateboundaries are traversed by subvertical transparent zones suggesting transpressional and trantensional environments. The BABEL lines image how the core of Baltica was formed by sequential accretion of microcontinents and arc terranes at the old continental margin during the Svecofennian Orogeny ~1.9-1.8 Ga .When Baltica joined the Columbia supercontinent, new terranes were added to its southern edge in the Sveocbaltic Orogeny (~1.8 Ga). During the dispersal of the Columbia, the Baltic Sea failed rift was formed, rapakivi granitoids were intruded and sedimentary basins were developed. An extended plate margin structure has been imposed on the Rodinian (Sveconorwegian) and Pangean additions (Variscan-Caledonian). Major crustal thinning takes place along a series of subvertical faults across the Trans-European Suture Zone marking the transition from Phanerozoic to Proterozoic Europe.

    In 2004, nuclear power plants were operated and/or built in eighteen European countries. Thirteen of these countries are members of EU-25. Five of the ten countries joining the European Union on May 1, 2004 operate nuclear power stations. A total of 206 power reactors with a gross power of 181,941 MWe and a net power of 172,699 MWe were in operation at the end of the year. In 2004, one nuclear power plant was commissioned in Russia (Kalinin 3), two (Kmelnitzki 2 and Rowno 4) in Ukraine. Five nuclear power plants were decommissioned in Europe in the course of 2004. As announced in 2000, the Chapelcross 1 to Chapelcross 4 plants in Britain were shut down for economic reasons. In Lithuania, the Ignalina 1 unit was disconnected from the power grid, as had been demanded by the EU Commission within the framework of the negotiations about the country's accession to the EU. As a result of ongoing technical optimization in some plants, involving increases in reactor power or generator power as well as commissioning of plants of higher capacity, nuclear generating capacity increased by approx. 1.5 GW. In late 2004, four nuclear generating units were under construction in Finland (1), Romania (1), and Russia (2). 150 nuclear power plants were operated in thirteen states of the European Union (EU-25), which is sixteen more than the year before as a consequence of the accession of new countries. They had an aggregate gross power of 137,943 MWe and a net power of 131,267 MWe, generating approx. 983 billion gross kWh of electricity in 2003, thus again contributing some 32% to the public electricity supply in the EU-25. In largest share of nuclear power in electricity generation is found in Lithuania (80%), followed by 78% in France, 57% in the Slovak Republic, 56% in Belgium, and 46% in Ukraine. In several countries not operating nuclear power plants of their own, such as Italy, Portugal, and Austria, nuclear power makes considerable contributions to public electricity supply as

    In 2005, nuclear power plants were operated and/or built in eighteen European countries. Thirteen of these countries are members of EU-25. Five of the ten countries joining the European Union on May 1, 2004 operate nuclear power stations. A total of 204 power reactors with a gross power of 181,030 MWe and a net power of 171,8479 MWe were in operation at the end of the year. In 2005, no nuclear power plant was commissioned. Two nuclear power plants were decommissioned in Europe in the course of 2005. In Germany the Obrigheim NPP and in Sweden the Barsebaeck 2 NPP have been permanently shut down due to political decisions. As a result of ongoing technical optimization in some plants, involving increases in reactor power or generator power as well as commissioning of plants of higher capacity, nuclear generating capacity increased by approx. 1.6 GW. In late 2005, five nuclear generating units were under construction in Finland (1), Romania (1), and Russia (3). 148 nuclear power plants were operated in thirteen states of the European Union (EU-25). They had an aggregate gross power of 137,023 MWe and a net power of 130,415 MWe, generating approx. 970 billion gross kWh of electricity in 2005, thus again contributing some 31% to the public electricity supply in the EU-25. In largest share of nuclear power in electricity generation is found in France (80%), followed by 72% in Lithuania, 55% in the Slovak Republic, 55% in Belgium, and 51% in Ukraine. In several countries not operating nuclear power plants of their own, such as Italy, Portugal, and Austria, nuclear power makes considerable contributions to public electricity supply as a result of electricity imports.

    North Carolina (NC) is one of the most forested states, and supports a major wood products industry. The NC Department of Natural Resources sponsored a study by Research Triangle Institute to examine new, productive uses of the State`s wood resources, especially electric power generation by co-firing with coal. This paper summarizes our research of the main factors influencing wood power generation opportunities, i.e., (1) electricity demand; (2) initiative and experience of developers; (3) available fuel resources; (4) incentives for alternate fuels; and (5) power plant technology and economics. The results cover NC forests, short rotation woody crops, existing wood energy facilities, electrical power requirements, and environmental regulations/incentives. Quantitative assessments are based on the interests of government agencies, utilities, electric cooperatives, developers and independent power producers, forest products industries, and the general public. Several specific, new opportunities for wood-to-electricity in the State are identified and described. Comparisons are made with nationwide resources and wood energy operations. Preferred approaches in NC are co-generation in existing or modified boilers and in dedicated wood power plants in forest industry regions. Co-firing is mainly an option for supplementing unreliable primary fuel supplies to existing boilers.

    2007-12-01

    This economical study answers the following questions: what is the dynamics of European power markets? What is the relative competitiveness of the different power production means? What are the determining factors of electricity wholesale prices? Who are the operators the most threatened by the rise of wholesale prices? To what extend power producers are impacted by the CO 2 constrain? Who are the most efficient producers? The analysis is based on 18 of the most representative groups of the European electric utilities. The first volume of the study presents the strategic perspectives of European power producers: dynamics and basic characteristics of European power markets, strategic options of European operators, typology and financial results of European power producers, scenarios of market reorganization according to Eurostaf (possible mega-mergers in the future, competition). Volume 2 makes a detailed analysis of the positioning and perspectives of the 18 selected groups: key figures, sourcing strategies, production means management, Eurostaf's diagnosis. (J.S.)

    Full Text Available This article discusses European Union (EU-North Africa energy relations with a special focus on renewables in North Africa, arguing that the research so far has not taken due account of North African perceptions of EU external energy policy. It is argued that current research on EU-North African relations has not taken sufficient note of the multidimensionality of energy or addressed the inconsistent nature of EU policy making. However, addressing these issues is vital in approaching EU-North Africa energy relations and EU policy towards North Africa in general. The study of perceptions is introduced as one way to develop research further, to give further impetus on understanding how EU-North African energy relations develop and to understand energy relations in their complexity.

    In the nuclear power sector, the main concern for the candidate countries entering the European Union, remains the nuclear safety. New standards and regulation will be issued for improving the general quality of life in a sound environment. For the candidate countries entering the European Union, this situation represents a real challenge. Their national legislation must be improved to meet the European standards. The conditions are different from country to country, and more difficult for those, which operate ''non west European reactor type''. The paper also present the actual status of the Romanian legislation related to nuclear power and environment. There are presented the principles, terms and responsibilities contained in this legislation. The authors discuss some aspects related to the possibilities to improve the national legislation to meet the actual European Commission or EURATOM standards. (author)

    Natural gas can, of course, be transported over very long distances but, because of the economics of gas transmission, its impact is most often local. This has certainly been the case with North Sea gas, which has clearly contributed significantly to European energy supply and will continue to do so for some time to come. The historical importance of the discovery of gas in the North Sea has been that it has enabled natural gas industries to grow rapidly in North West Europe. Without North Sea gas and Dutch gas it is difficult to see how town gas would have been replaced in North West Europe. Certainly, a much smaller natural gas industry would have emerged. North Sea gas has inevitably had the greatest impact on gas markets in the countries of the European Community and this will remain the case in future. Nevertheless, it is inevitable that gas will, in future, flow across more national boundaries than in the past, and that North Sea gas will have an important part to play in meeting the Central European demand for competitively priced, secure supplies. This paper discusses the United Kingdom market for gas and future demand both in the United Kingdom and more widely in Europe. An examination of the availability of gas supplies from the North Sea suggests that it is unlikely that there will be a surplus of gas for export from the United Kingdom continental shelf. Norway will remain the main source of exports, with the Netherlands also in a strong position. Transportation and political aspects are also considered. (author)

    Full Text Available Integration is one of the main consequences of globalization. Elements of microsystems are growing closer, which brings to the foreground problems of interaction and — in a longer perspective — those of close cooperation between different social systems. The article considers the case of North-West Russia, the only territory having a common border with the EU, in order to examine the issue of Russia using the geographical factor, which Otto von Bismarck called the most powerful and intrinsic factor in history. The significance of this factor increased after the Cold War. It was then when the independent Baltic States became a platform for emergence and recognition of the Baltic Sea region. The author focuses on the social and cultural integrity of the region and considers the traditional Nordic countries and the Baltic Sea states as interrelated components of a single region, different from other European regions in terms of economic interests, as well as its natural and sociocultural landscape.

    The requirement for energy worldwide is going to rise dramatically in the next few years and decades. Despite all developments of renewable energy sources, and despite the expansion of nuclear power in some industrialized countries and emerging countries, coal will turn out to be the key source of energy in the 21st century. Europe as a whole has a lot to offer which strengthens its position with respect to present and future requirements to be met in the construction of new power plants as well as in electricity and power supplies. As regards nuclear power in Germany, if it is to be given another chance, we must seek a dialog, pointing out that - nuclear power offers advantages in ensuring energy supply in Germany, given the development in the world energy markets; - nuclear power makes an important contribution to climate protection; - Germany's energy supply must be adapted to the global situation; - nuclear power offers opportunities in education, training, research and development; - nuclear power is contributing massively to our economic prosperity. The future viability of European power supply will not depend on the debate about nuclear power in Germany. The debate will be decided chiefly by the world market and on a European level. (orig.)

    From 1991 through 1996 the European Union signed the Association Agreements with ten East European countries (EE10), namely: Czech Republic, Estonia, Hungary, Poland, Slovenia, Latvia, Lithuania, Slovakia, Bulgaria and Romania. In the period 1994-1996 European Union received membership applications from all ten countries. The paper analyzes the approach of complying the requirements and regulations for European Union accession in the field of the Romanian nuclear power based on the CANDU technology. In this process, the real challenge is represented by the preparation and implementation of new regulations aiming to improve the general business environment by introducing International Accounting Standards simplification of bankruptcy laws, reform of taxation procedures and secureness of financial instruments. A new stand-by agreement with the International Monetary Fund and World Bank was set out in late April 1999 for an one-year loan of 475 million dollars. (authors)

  19. Pathways for the North European electricity supply

    International Nuclear Information System (INIS)

    Odenberger, M.; Unger, T.; Johnsson, F.

    2009-01-01

    This paper investigates the development of the electricity-supply systems in Northern Europe (Germany, UK, Denmark, Finland, Sweden and Norway) until the year 2050. The focus is on the response to an assumed common stringent CO 2 -reduction target and on the role of carbon capture and storage technologies (CCS). Special emphasis is put on turn-over in capital stock, timing of investments and the infrastructural implications of large-scale introduction of CCS. The analysis is carried out through scenario analysis with the aid of a techno-economic model, in which a case including CCS is compared to a case excluding this option. The phase out of the present capital stock (power plants) is included from the Chalmers energy infrastructure databases, which gives information on present and planned power plants down to block level for plants exceeding 10 MW net electric power. Assuming technical lifetimes for these plants yield residual capacities in each year, here referred to as the phase-out pattern. CCS technologies are assumed to become commercially available in 2020. The age structure of the power plants indicate that full turn-over in capital stock will take several decades with the present generation capacities accounting for around 50% of generated electricity in 2020. The results show that CO 2 emission reductions of 20% and 60% by the years 2020 and 2050, respectively, relative to 1990, can be met at a marginal cost of abatement of about 25-40 Euro /ton CO 2 over the period studied if CCS is included as an option from 2020. At the same time the marginal cost of generating electricity lies in the range 45-60 Euro /MWh. Excluding CCS raises the marginal cost of abatement with about 10 Euro /ton CO 2 , whereas the marginal cost of electricity generation increases with roughly 5-10 Euro /MWh. The CO 2 target by the year 2020 is met by implementation of renewable electricity and fuel shifting from coal to gas. After 2020 CCS technologies constitute an attractive way

    It is well known that the North Atlantic strongly influences European climate. Only few studies exist that focus on its impact on climate extremes. We are interested in these extremes and the processes and mechanisms behind it. For the analysis of the North Atlantic Oscillation (NAO) we use simulations performed with the Max Planck Institute for Meteorology Earth System Model (MPI-ESM). The NAO has a strong impact especially on European winter and the changes in minimum temperature are even larger than in maximum temperature. The impact of the Atlantic Multi-decadal Variability (AMV) on climate extremes is analyzed in ECHAM6 simulations forced with AMV warm and AMV cold sea surface temperature patterns. We analyze different extreme indices and try to understand the processes.

    There is no doubt about the importance of North Sea oil to the energy supply of the European Community. One might however be used to it and forget about the nature and the size of its impact on our economies. Firstly, this paper intends to estimate this impact - past, present and future. Secondly, a more qualitative approach will explore possible consequences of the implementation of the internal market for North Sea oil. Thirdly, the assistance given by the Community to innovative technologies which enabled North Sea oil to contribute, under better economic conditions and within a safer environment, to our supply is recalled. And finally, some remarks on energy policy form an EC perspective, are offered. (author)

    2017-11-01

    Poland's accession to the European Union has reduced the remnants of import barriers. Moreover, the consolidation and commercialization of the energy sector, the implementation of climate package elements and a whole host of other determinants have caused hard coal mining to begin functioning in a highly competitive market, and its negotiating position, as well as the possibility of survival, depends not only on the level of coal prices in international markets, but also on internal competition. This paper discusses the position of power coal on international markets and presents some current problems concerning the functioning of particular segments of the hard coal market in the European Union and Poland in terms of opportunities and threats that are a result of climate and energy policy.

    Livi-bacci, M

    1994-01-01

    This work compares attitudes toward immigration in Europe and North America. Europe has adopted and reinforced a restrictive immigration policy since the 1970s, but family reunification and asylum for refugees have replaced labor migration to maintain the flow of newcomers over the past two decades. Illegal immigration has increased in countries such as Italy and Spain where immigration is a recent phenomenon. Migratory pressure from the former Soviet block, violence against immigrants in Germany and elsewhere, the crisis of social protection systems, economic recession and increasing unemployment have pressured European governments to reinforce their closed door policy. In the US, restrictions against immigration have relaxed greatly since adoption of the Immigration Reform and Control Act in 1986. Over 800,000 immigrants have been admitted annually to the US in recent years. The factors explaining the different immigration policies in North America and Europe are not economic or demographic, but stem rather from history, social structure, the functioning of the labor market and social mobility. North America, more than Europe, has a positive view of immigration as contributing to the vitality and renewal of the culture and promoting development by broadening experience and knowledge. Immigration is regarded in Europe as, at best, a necessity in times of labor shortage and economic expansion. European countries tend to perceive themselves as totally formed and not requiring further cultural contribution. Homogeneity in culture, language, and religion is valued. Social mobility is possible in North America through professional success, but in the older and more hierarchical societies of Europe, social status is determined by birth and family or other connections. Since the early 1990s, public opinion toward immigration has become less favorable on both sides of the Atlantic, with increasing proportions favoring limitation. The positive perception of immigration in

    1997-11-01

    For 41 toothpastes available to European consumers in 1995, the cleaning efficacy was evaluated in comparison with abrasivity on dentin (RDA value). For cleaning power assessment, a modified pellicle cleaning ratio (PCR) measurement method was developed. The method is characterized by a five-day tea-staining procedure on bovine front teeth slabs on a rotating wheel, standardized brushing of the slabs in a V8 cross-brushing machine, and brightness measurement by a chromametric technique. All tested products were in accordance with the new DIN/ISO standard 11,609 for toothpastes in terms of dentin abrasivity. Not a single product exceeded an RDA value of 200. The majority of toothpastes (80%) had an RDA value below 100. Only three products surpassed the reference in cleaning power. Most products (73%) had a cleaning power (PCR value) between 20 and 80. The correlation between cleaning power and dentin abrasion was low (r = 0.66), which can be explained with the different influence on dentin and stains by factors like abrasive type, particle surface and size, as well as the chemical influence of other toothpaste ingredients. Some major trends could be shown on the basis of abrasive types. The ratio PCR to RDA was rather good in most silica-based toothpastes. A lower ratio was found in some products containing calcium carbonate or aluminum trihydrate as the only abrasive. The addition of other abrasives, such as polishing alumina, showed improved cleaning power. Some active ingredients, especially sequenstrants such as sodium tripolyphosphate or AHBP, also improve the PCR/RDA ratio by stain-dissolving action without being abrasive. The data for some special anti-stain products did not differ significantly from standard products. Compared with data measured in 1988, a general trend toward reduced abrasivity without loss of cleaning efficacy could be noticed on the European toothpaste market. This may be mostly due to the increased use of high-performance abrasives such

    The most important way to acquire cross border transmission rights in the North West European electricity market is through explicit auctions. Although market driven flexibility and therefore efficiency can be further enhanced. One way to this is to introduce a secondary market for transmission rights. In this paper the North West European Market Parties Platform (NWE MPP) proposes a model that is developed and preferred by the market parties. The paper will provide a converging contribution to the congestion management discussions in the North Western European region

    The author analyzes and compares the trade situation in the European Community (EC) with the North American Free Trade Agreement (NAFTA). He finds that "while both the EC and NAFTA are designed to provide trade preferences to the member countries, the two groupings differ markedly in other respects. The Treaty of Rome, establishing what is now the EC, consciously used economic means to foster political cohesion in Western Europe; whereas, the NAFTA negotiations seek free trade rather than more comprehensive economic integration precisely to minimize political content. The EC contains many social provisions absent from the NAFTA discussions, the most important of which is the right of migration from one EC country to another." The effects of NAFTA on the economy of Mexico and on Mexican migration to the United States are also assessed. excerpt

    The primary objective of Working Group 2 of Project MARINA was to consider recent measurements of environmental radioactivity in north European waters and to use this, and other information, to report likely magnitude of doses to the critical group from marine pathways. The monitoring data were supplemented, where appropriate, with predictions from simple models. The major sources of radioactivity studied were as follows: (i) liquid wastes from nuclear fuel reprocessing plants, (Sellafield, Dounreay, Cap de la Hague); (ii) liquid wastes from nuclear power plants and other major nuclear industry sites, (including Belgium, Denmark, France, Finland, GDR, FDR, Netherlands, Sweden, UK, USSR); (iii) solid waste disposal in the deep north-east Atlantic; (iv) fallout from Chernobyl; and (v) naturally-occurring radionuclides.

  9. The European Union and Iranian Nuclear Power

    Drevet, Jean-Francois

    2015-01-01

    On 14 July 2015, after 12 years of repeated crises around the nuclear issue and the ambitions of Iran in that regard, an agreement was finally signed between Tehran and the members of the UN Security Council plus Germany. Restriction on the enrichment of uranium and the production of plutonium, a strengthening of the inspection regime, the lifting of sanctions against Iran from 2016 onwards, maintaining the arms embargo - these are, broadly speaking, the outlines of this agreement. It will become clear over time how it is to be applied. Above and beyond these aspects, it is probably in the negotiation process that led to the agreement that the greatest lessons are to be learned, at least for the European Union. After reminding us of the context and the role played by economic and financial sanctions, Jean-Francois Drevet goes more precisely into the analysis of the new role the Union has assumed in this diplomatic territory, showing the extent to which 'soft power', as seen in this negotiation, could apply to other conflicts, beginning with those in the Middle East.

  10. East European nuclear power plant review

    International Nuclear Information System (INIS)

    Thomas, Steve

    1993-01-01

    Western public opinion regards East European nuclear power plants as inefficient and dangerous. However the plants achieve consistently good operating performances. The load factors achieved by each type of plant by country in 1991 are tabulated. These are shown to be good, especially the Hungarian plant. Load factors seem to be dependent on the type of plant rather than where they were installed. WWER 213s worked better than the WWER 320s. This was because of long shutdowns to try and bring the safety standards up to acceptable levels. RBMK performances were depressed because of a 30% derating by safety authorities on 8 out of the 15 units operating. Overall the picture in Eastern Europe is encouraging with improvements in safety related indicators such as break-down frequency whilst the plants still achieve respectable load factors. The performance of the WWER 320s is particularly encouraging. Good load factors from this type of plant in Russia, the Ukraine and Bulgaria may allow older unsafe plant to be phased out. (UK)

  11. Migration and tourism entrepreneurship: North-European immigrants in Cataluna and Languedoc.

    Lardies, R

    1999-01-01

    This paper examines new North European immigration into two Mediterranean regions and identifies the characteristics of North European entrepreneurs who work in small tourist businesses. Data used for analyses were gathered from 169 questionnaires addressed to small tourism firms and other tourism-related businesses in Cataluna (Spain) and Languedo (France). Also, the North European entrepreneurs are examined within the context of new migration flows into South European regions from the north of the continent. As for the reasons for moving to these South European regions, company formation and the style of running the businesses are found to be less motivated by the need for work than by lifestyle considerations. The results suggest that international migration theory offers little to explain these new migratory flows.

    The right energy mix is decisive. The European Commission feels that nuclear power can make an important contribution towards sustainable energy supply in Europe. Nuclear power should keep its place in the European energy mix. One important aspect in this regard is improved public acceptance through communication, transparency, and confidence building. High safety standards and a credible approach to the safe long-term management of radioactive waste are major components of this sustainable energy source. (orig./GL)

    2012-09-06

    Due to its clean burning properties, low investment costs and flexibility in production, natural gas is often put forward as the ideal partner fuel for wind power and other renewable sources of electricity generation with strongly variable output. This working paper examines three vital questions associated with this premise: 1) Is natural gas indeed the best partner fuel for wind power? 2) If so, to what extent will an increasing market share of wind power in European electricity generation affect demand for natural gas in the power sector? and 3) Considering the existing European natural gas markets, is natural gas capable of fulfilling this role of partner for renewable sources of electricity?.

    To evaluate differences in the inclusion of anesthesiologists in mobile extracorporeal membrane oxygenation (ECMO) teams between North American and European centers. A retrospective review of North American versus European mobile ECMO teams. The search terms used to identify relevant articles were the following: "extracorporeal membrane transport," "mobile ECMO," and "interhospital transport." MEDLINE review of articles. None. None. Between 1986 and 2015, 25 articles were published that reported the personnel makeup of mobile ECMO teams in North America and Europe: 6 from North American centers and 19 from European centers. The included articles reported a total of 1,329 cases: 389 (29%) adult-only cohorts and 940 (71%) mixed-age cohorts. Among North American studies, 0 of 6 (0%) reported the presence of an anesthesiologist on the mobile ECMO team in contrast to European studies, in which 10 of 19 (53%) reported the inclusion of an anesthesiologist (Fisher exact p for difference = 0.05). In terms of number of cases, this discrepancy translated to 543 total cases in North America (all without an anesthesiologist) and 499 cases in Europe (37%) including an anesthesiologist on the team (Fisher exact p for difference<0.001). This study demonstrated significant geographic discrepancies in the inclusion of anesthesiologists on mobile ECMO teams, with European centers more likely to incorporate an anesthesiologist into the mobile ECMO process compared with North American centers.

    The storage and balancing needs of a simplified European power system, which is based on wind and solar power generation only, are derived from an extensive weather-driven modeling of hourly power mismatches between generation and load. The storage energy capacity, the annual balancing energy...... and the balancing power are found to depend significantly on the mixing ratio between wind and solar power generation. They decrease strongly with the overall excess generation. At 50% excess generation the required long-term storage energy capacity and annual balancing energy amount to 1% of the annual consumption....... The required balancing power turns out to be 25% of the average hourly load. These numbers are in agreement with current hydro storage lakes in Scandinavia and the Alps, as well as with potential hydrogen storage in mostly North-German salt caverns....

    1988-01-01

    Statistical and prognostic data were compared characterizing the development of the power industry, electric power generation and nuclear power in the CSSR and in other European countries. The penetration of nuclear power into the power industry of the individual countries is affected especially by the economic necessity of changing the level and structure of the respective country's national economy with primary power resources and electric power. The analysis shows among others that nuclear energy has become most widely introduced in countries where electric power makes up a high proportion of the power balance and where the country only has an average amount of primary power resources. By the year 2000 nuclear power is envisaged to make up 27.5 to 32.2% of total power output which corresponds to an annual increase of 5.6% in the power output of nuclear power plants. The dependence of Czechoslovakia's increase of power output on nuclear power is greater than that of both the European capitalist and socialist countries. (Z.M.). 1 fig., 4 tabs., 5 refs

    Trajectories of gender identity were examined from Grade 6 (M age  = 11.9 years) to Grade 9 in European French (n = 570) and North African French (n = 534) adolescents, and gender and ethnic group differences were assessed in these trajectories. In Grade 6, boys of both ethnic groups reported higher levels of gender typicality and felt pressure for gender conformity than girls. European French girls and boys and North African French girls reported decreasing gender typicality from Grade 6 to Grade 9, whereas North African French boys did not change. Felt pressure decreased among girls, did not change in European French boys, and increased in North African French boys. Ethnic and gender differences in gender identity development are discussed. © 2017 The Authors. Child Development © 2017 Society for Research in Child Development, Inc.

    1989-01-01

    The primary objective of Working Group 2 of Project MARINA was to consider recent measurements of environmental radioactivity in north European waters and to use this, and other information, to report the likely magnitude of doses to the critical group from marine pathways. The monitoring data were supplemented, where appropriate, with predictions from simple models. The major sources of radioactivity studied were as follows: (i) liquid wastes from nuclear fuel reprocessing plants; (ii) liquid wastes from nuclear power plants and other major nuclear industry sites; (iii) solid waste disposal in the deep north-east Atlantic; (iv) fallout from Chernobyl; and (v) naturally-occurring radionuclides. Some of the largest doses from marine pathways are predicted for naturally-occurring radionuclides. In this case, the dominant radionuclide is polonium-210 and the dominant pathway is via consumption of molluscan species. The highest doses from the nuclear industry were due to the operation of the reprocessing plant at Sellafield. Discharges from this site have been decreasing substantially in recent years and, as a consequence, doses have also been reducing. (author).

    Oil, coal and natural gas dominate the energy consumption in Northern Europe, as well as in the world at large. The energy supply mix varies between the countries of the region. For example, a large proportion of biomass and waste in Finland and Latvia (Norway) and Sweden use a high proportion of hydroelectric power, while Poland has a very high proportion of coal in their energy mix. Energy use per person in Northern Europe is more than twice as high compared with the average global - but lower than the average in the OECD. In Northern Europe, there are three separate networks for energy transfer: natural gas, electricity and heating. The expansion of the natural gas network has been strong since 1970. Gas pipelines today covers large parts of Europe and new pipelines are planned. The electricity grids and their transmission capacity has grown. Electricity began to be transferred between the Nordic countries during the 1960s. Today, the North European countries are linked with a number of high capacity cables. While the networks for district heating has grown, these systems are separate for individual cities. In recent years, the region's net imports of oil rose, as (Norway's oil production has declined since the early 2000s. On the other hand, the North European countries in 2007 became, for the first time, net exporters of natural gas. As the energy systems expand, trade in energy increases - both within the region and with the rest of Europe and the rest of the world. Several new energy projects are planned in Northern Europe for expanded capacity in oil refineries and new pipelines for natural gas and transmission lines for electricity. The energy integration in the region is therefore expected to increase further. In the long term, climate policy will be of greater importance, both for the region's use of primary energy and for the look of the region's future energy map

  8. Fruitful symbiosis: Why an export bundled with wind energy is the most feasible option for North African concentrated solar power

    International Nuclear Information System (INIS)

    Kost, Christoph; Pfluger, Benjamin; Eichhammer, Wolfgang; Ragwitz, Mario

    2011-01-01

    The idea of generating electricity in North Africa using concentrating solar thermal power (CSP) has been around for some time now but has recently gained momentum through the Mediterranean Solar Plan (MSP) and the formation of the Desertec Industrial Initiative. This paper argues that while the large-scale deployment of CSP in North Africa does not seem economically attractive for either European or African institutions or countries on their own at present, combining domestic use and electricity exports could be profitable for both parties. A detailed economic portfolio covering both solar and wind power plants can achieve competitive price levels, which would accelerate the diffusion of solar technology in North Africa. This portfolio could be financed partially by exporting electricity from solar thermal plants in North Africa via HVDC interconnections to European consumers. Sharing the costs in this way makes it possible to generate solar electricity for the domestic market at a reasonable cost. Some of the electricity produced from the solar power plants and wind parks in North Africa is sold on European energy markets in the form of a long-term contracted solar-wind portfolio, which would qualify for support from the financial incentive schemes of the European Member States (e.g. feed-in tariffs). This transfer of green electricity could help to meet the targets for energy from renewable energy sources (RES) in the EU Member States as the new EU Directive of 2009 opened the European electricity market to imports from third states. - Research highlights: → This paper describes a feasible approach to financing a larger deployment of CSP in North Africa. → The proposed portfolio includes local consumption and electricity export to Europe. → Bundling wind with solar power as a business model for exporting solar electricity. → Prices of the solar-wind mix are competitive with other renewable energy sources. → Scenario outlook for the North African CSP

    2010-01-01

    Learning from operational experience and applying this knowledge promptly and intelligently is one of the ways to improve the safety of Nuclear Power Plant (NPP). Recent reviews of the effectiveness of Operational Experience Feedback (OEF) systems have pointed to the need for further improvement, with importance being placed on tailoring the information to the needs of the regulators. In 2007, at the request of a number of nuclear safety regulatory authorities in Europe, the Institute for Energy of the European Commission's Joint Research Centre (EC JRC) initiated a project on Nuclear Power Plant operational experience feedback, which adopts an integrated approach to the research needed to strengthen the European capabilities for assessment of NPP operational events and to promote the development of tools and mechanisms for the improved application of the lessons learned. Consequently, a so-called ''European Clearinghouse'' on NPP OEF was established, which includes scientific officers from the EC JRC, a number of European nuclear safety regulatory authorities and some of their Technical Support Organizations (TSOs). The paper discusses the activities implemented in 2008 within the framework of the European Clearinghouse on NPP OEF (hereinafter called the European NPP Clearinghouse) and provides an overview of the main conclusions drawn from the safety studies performed. Outlook of the activities carried out in 2009 are given. (orig.)

    Making conservative assumptions on the development of energy demand, the major requirements in terms of annual and cumulative uranium, separative work, reprocessing capacity and fossile fuel are reviewed for a reference case assuming the use of conventional, LWR, FBR power stations and recycle of plutonium in thermal reactors. A very long-term view is taken to show how the long-term future is affected by decisions taken in the medium-term future. A saturation of the demand is assumed in the long term, both because this assumption seems to be reasonable and because it helps making the scenario simpler and our arguments clearer. Four main conclusions are drawn: (1) Even assuming that conventional power stations are used in the long term only to cover peak-load demand, the number of conventional stations and the fossil-fuel consumption will be quite large. (2) Supplying enough uranium and enrichment capacity will pose formidable problems, particularly in view of the large increase in the demand in the last decades of our century. (3) Fast breeder reactors should be used to considerably reduce such demands. In any case, the availability of large reprocessing capacity is a must. (4) From the analysis of the sensitivity of the results to FBR breeding ratio and to the out-of-pile time (due to cooling and reprocessing), the conclusion is drawn that both are very important, the latter being more important in the short term, the former in the long term. The achievement of an advanced reprocessing technology must be considered as a primary development goal. (author)

  14. Issues related to gas use by European power utilities

    International Nuclear Information System (INIS)

    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

    In recent times a large number of studies have investigated the various policies which can be followed to satisfy a given electric energy demand. Installation policies concerning conventional stations and several types of nuclear stations have been analyzed from the point of view of consumptions, expenditures, investments etc. The exercise is usually repeated for several demand-growth curves. Sometimes an optimization of the power station installation policy based on minimizing consumption of a type of fuel or expenditures is made. In the study presented here a different attitude is taken, in the sense that it is assumed that the energy demand growth will be large enough to justify the growth of nuclear energy production; this will be limited by a number of technological constraints, namely: 1- The Uranium delivery rate. This rate (tons/year) is assumed to increase from 1985 by 10% per annum and to reach a saturation level after a given number of years. 2- Availability of reprocessing capacity. It is assumed to increase with a given doubling time after 1985. 3- Development of reprocessing technology, which is represented here by the out-of-pile time of the fuel. 4-Availability and technology of fast reactors, represented by the year of first installlation and by their physical characteristics. All the values defining the above-mentioned constraints are varied parametrically and their effects on the penetration of thermal and fast reactors and on the consequent consumptions and expenditures are assessed. A few considerations on the demand of conventional energy resulting from such constraints and from various hypotheses on the total demand are made, to show that a considerable production of conventional energy must be foreseen in the next few decades

    operating reserves. To study the effects of these imbalances, anticipated wind scenarios for European power systems are modelled for 2020 and 2030. Wind power forecasts for different time scales and real-time available wind power are modelled. Based on these studies, this paper qualitatively analyzes......Wind power generation is expected to increase in Europe by large extent in future. This will increase variability and uncertainty in power systems. Imbalances caused due to uncertainty in wind power forecast can trigger frequency instability in the system. These imbalances are handled using...... the adequacy of primary and secondary reserves requirements for future European power systems.

    The report is the first in a series of three produced by the PowerClean Thematic Network that looks at and defines future requirements for research and development of fossil fuel power generation in the European Union. It makes the case for fossil fuel R & D with emphasis on the need for clean coal technologies (to increased efficiency and other CO{sub 2} capture and storage) For satisfying future energy demands of the enlarged European Union between now and 2030. The report concludes that affirmative R, D and D action is needed to support the EU power industry, working together on a Europe-wide basis, to establish the use of coal and other fossil fuels in near-zero emissions power plant. The role model would be the European Research Area, as in the Sixth Framework Programme (FP6), but with a more comprehensive range of technical objectives recognising the importance of fossil fuels. Section headings are: introduction; current energy use; future needs and requirements; the future for clean fossil fuel energy in Europe; comparison with approaches adopted elsewhere (USA Vision 21 and FutureGen programmes, Japan); and responsibilities for EU coal R, D & D. 14 refs., 9 figs., 4 tabs.

  20. What will become of the european nuclear power plant market

    International Nuclear Information System (INIS)

    Goulden, O.A.

    1976-01-01

    In a forecast of the development of the future market for power plants and components in Europe a British consultant comes to the conclusion that the nuclear power programs established in various countries in 1974 are oversized in the light of the reduction in the increment of electricity consumption, which is expected to continue, if they are implemented in addition to existing and planned conventional thermal power stations, and that these programs are too costly if they are intended more or less only to substitute for other sources of energy. A streamlining process, which is deemed to be inescapable, is bound to result in a major cutback of the nuclear power station market in Europe and in a hard fight for survival among the power plant manufacturers now in the market. In the author's opinion, the only way out would be a uniform European electricity generation, transmission and distribution system with all the rationalization effects this would entail. (orig.) [de

    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....

    Full Text Available This paper evaluates, for a 2030 scenario, the impact on onshore power systems in terms of the variability of the power generated by 81 GW of offshore wind farms installed in the North Sea. Meso-scale reanalysis data are used as input for computing the hourly power production for offshore wind farms, and this total production is analyzed to identify the largest aggregated hourly power variations. Based on publicly available information, a simplified representation of the coastal power grid is built for the countries bordering the North Sea. Wind farms less than 60 km from shore are connected radially to the mainland, while the rest are connected to a hypothetical offshore HVDC (High-Voltage Direct Current power grid, designed such that wind curtailment does not exceed 1% of production. Loads and conventional power plants by technology and associated cost curves are computed for the various national power systems, based on 2030 projections. Using the MATLAB-based MATPOWER toolbox, the hourly optimal power flow for this regional hybrid AC/DC grid is computed for high, low and medium years from the meso-scale database. The largest net load variations are evaluated per market area and related to the extra load-following reserves that may be needed from conventional generators.

    This article compares the important differences in the American College of Cardiology Foundation (ACCF)/American Heart Association (AHA)/Heart Rhythm Society (HRS), Canadian Cardiovascular Society (CCS), and European Society of Cardiology (ESC) 2010 guidelines on atrial fibrillation (AF). All guidelines recommend more lenient targets for ventricular rate control although the CCS guidelines recommend a target heart rate at rest guidelines accept a target heart rate at rest guidelines recommend that the choice of antiarrhythmic drug for maintenance of sinus rhythm be based on the underlying cardiovascular disease state. However, the CCS guidelines do not recommend that the use of Class IC drugs or sotalol be restricted in the presence of left ventricular hypertrophy alone. All the guidelines have incorporated dronedarone into their recommendations of antiarrhythmic drug therapy for maintenance of sinus rhythm. However, the CCS guidelines do not make a specific recommendation that the use of dronedarone is reasonable to decrease the risk of hospitalization for cardiovascular causes in patients with AF. The ACCF/AHA/HRS update makes a strong recommendation for catheter ablation in patients with paroxysmal AF who have failed a single anti-arrhythmic drug whereas the CCS and ESC guidelines make this a conditional recommendation. The CCS guidelines are the only guidelines at present that recommend dabigitran for prevention of stroke in high risk patients and suggest that dabigatran is preferred to warfarin for stroke prevention in most patient groups.

    After decades of stability the European power and gas industries are now undergoing fundamental changes. Made possible by policy reforms and technological developments, these changes are largely driven by commercial forces which have developed their own momentum and dynamics. New commercial risks are a key feature of the emerging market order and companies cannot protect themselves through a ''no move strategy''. This report explores the key changes and examines the emerging commercial strategies in response to the new environment. (author)

    2010-01-01

    In the European Union, in order to support the Community activities on operational experience, a centralized regional network on nuclear power plants operational experience feedback (European Clearinghouse on Operational Experience Feedback for Nuclear Power Plants) was established in 2008 at the EC JRC-IE, Petten (The Netherlands) on request of nuclear Safety Authorities of several Member States. Its main goal is to improve the communication and information sharing on OEF, to promote regional collaboration on analyses of operational experience and dissemination of the lessons learned. The enlarged EU Clearinghouse was launched in April 2010, and it is currently gathering the Regulatory Authorities of Finland, Hungary, Lithuania, the Netherlands, Romania, Slovenia, Switzerland, Bulgaria, Czec Republic, France, Germany, Slovak Republic, and Spain (these last six countries as observers). The OECD Nuclear Energy Agency, the IAEA, the EC Directorates General of the JRC and ENER are also part of the network. Recently, collaboration between some European Technical Support Organizations (such IRSN and GRS) and the EU Clearinghouse has been initiated. This paper explains in detail the objectives and organization of the EU Clearinghouse, as well as the most relevant activities carried out, like research work in trend analysis of events ocurred in NPP, topical reports on particular events, dissemination of the results, quarterly reports on events reported publicly and operational experience support to the members of the EU Clearinghouse.

    The subpolar North Atlantic is a key location for the Earth's climate system. In the Labrador Sea, intense winter air-sea heat exchange drives the formation of deep waters and the surface circulation of warm waters around the subpolar gyre. This process therefore has the ability to modulate the oceanic northward heat transport. Recent studies reveal decadal variability in the formation of Labrador Sea Water. Yet, crucially, its longer-term history and links with European climate remain limited. Here we present new decadally resolved marine proxy reconstructions, which suggest weakened Labrador Sea Water formation and gyre strength with similar timing to the centennial cold periods recorded in terrestrial climate archives and historical records over the last 3000 years. These new data support that subpolar North Atlantic circulation changes, likely forced by increased southward flow of Arctic waters, contributed to modulating the climate of Europe with important societal impacts as revealed in European history.

  12. Costs of reducing water use of concentrating solar power to sustainable levels: Scenarios for North Africa

    International Nuclear Information System (INIS)

    2011-01-01

    Concentrating solar power (CSP) has the potential to become a leading sustainable energy technology for the European electricity system. In order to reach a substantial share in the energy mix, European investment in CSP appears most profitable in North Africa, where solar potential is significantly higher than in southern Europe. As well as sufficient solar irradiance, however, the majority of today's CSP plants also require a considerable amount of water, primarily for cooling purposes. In this paper we examine water usage associated with CSP in North Africa, and the cost penalties associated with technologies that could reduce those needs. We inspect four representative sites to compare the ecological and economical drawbacks from conventional and alternative cooling systems, depending on the local environment, and including an outlook with climate change to the mid-century. Scaling our results up to a regional level indicates that the use of wet cooling technologies would likely be unsustainable. Dry cooling systems, as well as sourcing of alternative water supplies, would allow for sustainable operation. Their cost penalty would be minor compared to the variance in CSP costs due to different average solar irradiance values. - Highlights: → Scaling up CSP with wet cooling from ground water will be unsustainable in North Africa. → Desalination and alternative cooling systems can assure a sustainable water supply. → On large-scale, the cost penalties of alternative cooling technologies appear minor.

    To address the relationship between years lived with a disability (YLDs), prevalence and cost of neurological diseases, and to test whether there is a European North-South gradient for national health expenditure, disability, costs and prevalence of neurological diseases. Information on costs, prevalence and YLDs referred to 2010 were taken from the Study on the Cost of Disorders of the Brain and from the Global Burden of Disease study; data on health expenditure were taken from OECD reports. Selected conditions were as follows: brain tumours, stroke, dementia, Parkinson's disease, epilepsy, multiple sclerosis, migraine and tension-type headache; selected countries were from North (Denmark, Finland, Norway, Sweden) and South (Greece, Italy, Portugal, Spain) Europe. The association between the variables for each condition was tested using Spearman's correlation; Wilcoxon signed ranks test was used to test North-South Europe differences. Correlations were largely non-significant (except for stroke). YLDs and cost were generally lower in South-European countries, and prevalence was lower in North-European countries, but no significant differences were found. Health expenditure, YLDs, costs and prevalence of neurological conditions were generally not correlated across the eight countries. A clear North-South gradient was found for health expenditures, and partially for YLDs, costs and diseases' prevalence. We hypothesized that this is a consequence of the expansion of morbidity of neurological conditions connected to ageing, that health and welfare systems of selected countries were not prepared to face. © 2014 John Wiley & Sons A/S.

    Perez, Yannick

    2002-01-01

    This research thesis reports a comparative analysis of reforms of the electric power sector implemented in European countries. In the first part, the authors proposes a presentation of the theoretical framework adopted for this analysis which is notably based on the New Institutional Economy approach. He also proposes an approach to the electric power industry based on the Transaction Cost Theory, and presents an overview of the various European reforms in the field of electricity, and of still unresolved problems which emerged after the creation of different power markets. The next part addresses an assessment of the attractive and desirable characters of reforms which have been implemented in the United Kingdom, in Germany and in Spain, with an attempt to identify winners and losers, and to classify these reforms. In the third part, the author defines a framework for the analysis of the feasibility of reforms which combine institutional and industrial dimensions, notably by reference to Noll and Williamson works. In the last part, the author sheds a new light on the concept of credibility. He introduces the conventional arbitrage of the Transaction Cost Theory between commitment stability and flexibility to generate uncertainty. He notably shows that the main problem in centralised institutional environments, is to guarantee the stability of commitments in front of opportunism, whereas in decentralised institutional environments, the main problem is to produce flexibility to manage uncertainty [fr

    Full Text Available Soils of Russian European North were investigated in terms of stability and quality of organic matter as well as in terms of soils organic matter elemental composi­tion. Therefore, soil humic acids (HAs, extracted from soils of different natural zones of Russian North-East were studied to characterize the degree of soil organic matter stabilization along a zonal gradient. HAs were extracted from soil of different zonal environments of the Komi Republic: south, middle and north taiga as well as south tundra. Data on elemental composition of humic acids and fulvic acids (FAs extracted from different soil types were obtained to assess humus formation mechanisms in the soils of taiga and tundra of the European North-East of Russia. The specificity of HAs elemental composition are discussed in relation to environmental conditions. The higher moisture degree of taiga soils results in the higher H/C ratio in humic substances. This reflects the reduced microbiologic activity in Albeluvisols sods and subsequent conser­vation of carbohydrate and amino acid fragments in HAs. HAs of tundra soils, shows the H/C values decreasing within the depth of the soils, which reflects increasing of aromatic compounds in HA structure of mineral soil horizons. FAs were more oxidized and contains less carbon while compared with the HAs. Humic acids, extracted from soil of different polar and boreal environments differ in terms of elemental composition winch reflects the climatic and hydrological regimes of humification.

    Full Text Available Unlike European Schools of Public Health, whose development was primarily influenced by the medical profession and was linked to the healthcare system, North American Schools of Public Health operate as independent academic institutions engaged in research and education of Public Health specialists. While Public Health has been recognised as a distinctive profession in USA and Canada for almost a century, in many European countries it is not recognized as such and, accordingly, there are no well-defined job positions for graduates. Similarities and differences between the European and American Schools of Public Health are reviewed and the importance of classification of core competences, responsibilities and scope of knowledge required for Public Health practice was pointed out as a prerequisite for accreditation of study curricula. For the professionalization of Public Health in Europe further efforts are needed.

This model has producers as Cournot players with conjectured supply functions relative to their rivals. As such, these producers can withhold production to increase downstream prices for greater profits. The other players are taken to be perfectly competitive and are combined with extensive pipeline, seasonal, and other data reflecting the current state of the market. Four market scenarios are run to analyze the extent of market power by these producers as well as the importance of pipeline and storage capacity. (author)

    The dominant variability modes of the North Atlantic-European rotational flow are examined by applying a principal component analysis (PCA/EOF) to the 200 hPa streamfunction mid-winter anomalies (Jan-Feb monthly means). The results reveal that, when this norm is used, the leading mode (EOF1) does not correspond to the traditional North Atlantic Oscillation (NAO, which appears in our analysis as the second leading mode, EOF2) but is the local manifestation of the leading hemispheric streamfunction EOF. The regression of this regional mode onto the global SST field exhibits a clear El Nino signature, with no signal over the Atlantic, while the associated upper height anomalies resemble the Tropical/Northern Hemisphere (TNH) pattern. East of North America, this TNH-like wavetrain produces a meridional dipole-like pattern at lower levels. Although in some ways this pattern resembles the NAO (EOF2), the dynamics of these two modes are very different in that only EOF2 is associated with a latitudinal shift of the North Atlantic stormtrack. Thus, the choice of the streamfunction norm in the EOF analysis allows the separation of two different phenomena that can produce similar dipolar surface pressure anomalies over the North Atlantic but that have different impact on European climate. These two modes also differ on their contribution to variability at lower levels: while NAO-EOF2 is mostly confined to the North Atlantic, TNH-EOF1 has a more annular, global character. At upper levels NAO-EOF2 also produces a global pattern but with no annular structure, reminiscent of the ''circumglobal'' teleconnection. (orig.)

    Electromagnetic Interference (EMI) arising from a wide range of sources can threaten nuclear power plant operation. The need for measures to mitigate its effects have long been recognised although there are difference in approaches worldwide. The US industry approaches the problem by comprehensive site surveys defining an envelope of emissions for the environmental whilst the UK nuclear industry defined many years ago generic levels which cover power station environments. Moves to standardisation within the European community have led to slight changes in UK approach, in particular how large systems can be tested. The tests undertaken on UK nuclear plant include tests for immunity to conducted as well as radiated interference. Similar tests are also performed elsewhere in Europe but are not, to the authors` knowledge, commonly undertaken in the USA. Currently work is proceeding on draft international standards under the auspices of the IEC.

  4. The European Constitution: sovereignty, legitimacy and constituent power

    Directory of Open Access Journals (Sweden)

    Signe Larsen

    2014-06-01

    Full Text Available On the basis of Hannah Arendt’s and Carl Schmitt’s writings on the constituent power, this article sets out to develop an interpretative framework which would aid the understanding of the legitimation crisis of European integration initiated by the EU constitutional failure of 2004. The question raised in this essay is whether the successful establishment of democratic constitutional legitimacy is conditional upon the existence of a federal state. From the perspective of the constituent power, two opposing answers are given based on two rivalling notions of the ultimate meaning of constitutional politics: freedom and security. The article concludes that even though the EU as a case remains undecided, it seems likely that democracy and constitutional politics have parted ways in the EU both in the Arendtian and in the Schmittian sense. If that is the case, the constitutional crisis is a serious problem for the future of democracy in the EU.

    Full Text Available Information about the genetic diversity of potato germplasm in Iran is important for variety identification andto enhance the classification of germplasm collections and exploit them in breeding programs and for the development andintroduction of new varieties. AFLP fingerprinting was applied to a group of cultivated potato varieties to find if there is anygeographical differentiation in potato diversity from Europe and North America. The high level of polymorphism within potatovarieties and the high number of variety-specific bands suggest that AFLPs are powerful markers for diversity analysis inpotato varieties. No region-specific AFLP markers were found (present in varieties from the same origin and absent inothers. The UPGMA dendrogram revealed four distinct clusters corresponding almost to the geographical origin of thevarieties. However, the bootstrap support for branches was rather weak. No clusters clearly distinguished varieties fromEurope and North America. Varieties from the same geographical origins however tended to group together within eachcluster. The mean similarity and the UPGMA dendrogram both suggest that North American varieties have nearly identicalgenetic diversity to European varieties. The results of AMOVA revealed large within-region variations which accounted for94.5% of the total molecular variance. The between-region variation, although accounting for only 5.5% of the total variation,was statistically significant. AFLP technology was successfully used to evaluate diversity between different geographicalgroups of potatoes and is recommended for potato genetic studies.

    In the European market, the promotion of wind power leads to more network congestion. Zonal pricing (market coupling), which does not take the physical characteristics of transmission into account, is the most commonly used method to relieve congestion in Europe. Zonal pricing fails to provide adequate locational price signals regarding the energy resource scarcity and thus creates a large amount of unscheduled cross-border flows originating from wind-generated power, making the interconne...

  8. Perception of risks in renewable energy projects: The case of concentrated solar power in North Africa

    2012-01-01

    The world needs to reduce greenhouse gas emissions to prevent climate change, while meeting the energy needs of developed and developing economies. Recent studies suggest that generation of electricity from concentrated solar power in North African countries and its transmission to Europe could provide European and North African partners with low-carbon electricity.The private capital will be likely required to achieve the scale of new investment and yet the North African region experience difficulties with sustaining high levels of foreign direct investment from the private sector. The literature identifies a number of risks as barriers to investment, and we examine these in the particular context of renewable energy development. We conducted three stages of interviews with stakeholders to learn their perceptions of the risks most likely to affect renewable energy projects. Three class of risks—regulatory, political, and force majeure (which includes terrorism)—stand out as being of high concern. Of these, regulatory risks are perceived as being the most consequential, and the most likely to occur. This suggests that attention to building the capacities of North African countries to develop, implement, and enforce sound regulations in a transparent manner could be an important step in promoting renewable energy cooperation with Europe.

    The European Union has yet to determine how exactly to reach its greenhouse gas emissions targets for the future. One potential answer involves large-scale development of concentrated solar power (CSP) in the North African region, transmitting the power to Europe. CSP is a relatively young and little utilized technology and is expensive when compared to other methods of generation. Feasibility studies have shown it is possible to generate enough power from CSP plants in Africa to spearhead the EUs climate goals. However, the costs of such a project are less well known. Currently, CSP must compete with low cost coal-fired electricity plants, severely hindering development. We examine the possible investment costs required for North African CSP levelized electricity cost to equal those of coal-fired plants and the potential subsidy costs needed to encourage growth until the technologies reach price parity. We also examine the sensitivity of investment and subsidies to changes in key factors. We find that estimates of subsidy amounts are reasonable for the EU and that sensitivity to such factors as perceived risk and learning rates would enable policy-makers to positively influence the cost of subsidies and time required for CSP to be competitive with coal.

    Reduced operating costs, lower greenhouse gas emissions and security of supply are being cited by North Queensland industry leaders as the reasons for investing more than A$550 million to expand operations and convert to coal seam gas as their preferred fuel source. The article, by Enertrade, reports that just a few months after commissioning its North Queensland Gas Pipeline to transport coal seam gas from Moranbah to Townsville, Enertrade has signed contracts that will see combined cycle gas-fired baseload electricity generated in Townsville and the Queensland Nickel Refinery, and Xstrata Copper Refinery switch from liquid fuels to gas. The development has been driven by state government policy that 13% of Queensland's electricity be sourced from gas-fired power generation from 1 January 2005.

    The purpose of this study was to compare experiences and concerns about pouch seal leakage between persons with ostomies residing in North America (Canada and the United States) and Europe (United Kingdom, Netherlands, Sweden, Germany, Belgium, France, and Italy). Differences in reported pouch wear time and accessories used between the 2 groups were also examined. Secondary analysis of data from a cross-sectional study (Ostomy Life Study). Responses from persons residing in European countries (n = 1939) were compared with responses of 1387 individuals residing in North American countries. Persons with an ostomy completed a questionnaire that focused on 4 topics related to the daily use of an ostomy pouching system (pouch seal leakage, ballooning, appearance of pouching system such as color and size of the pouch and whether it is discrete under clothing, and coupling failure of 2-piece pouching systems). Pouch seal leakage was defined as stomal effluent seeping between the skin and the wafer of the ostomy pouching system. Statistical analysis was performed using a proportional odds model including various variable effects. Special attention was given to frequency of pouch seal leakage occurrences. All tests were 2-sided; P values ≤.05 were deemed statistically significant. Participants living in the North American countries indicated they were more likely to experience leakage from the ostomy (odds ratio = 2.610, 95% CI 2.187-3.115; P < .0001). Findings also indicated they were more likely to worry about pouch seal leakage than those in the European countries' data set (odds ratio = 2.722, 95% CI 2.283-3.246; P < .0001). Participants residing in the North American countries had significantly longer wear times than those participants in the European countries (P < .0001, χ test). The use of accessories was associated with a longer pouching system wear time. Study results suggest that participants from the North American countries indicated significantly more

    To investigate time-trend changes in the frequency of drunkenness among European and North American adolescents. Cross-sectional surveys in the 1997/1998 and 2005/2006 Health Behaviour in School-Aged Children Study (HBSC). High schools in 23 countries. A sample of 77 586 adolescents aged 15 years was analyzed by means of hierarchical linear modeling. The frequency of drunkenness. We observed a significant increase of about 40% in the mean frequency of drunkenness in all 7 participating Eastern European countries. This increase was evident among both genders, but most consistently among girls. Meanwhile, it declined in 13 of 16 Western countries, about 25% on average. Declines in Western countries were particularly notable among boys and in North America, Scandinavia, the United Kingdom, and Ireland. Despite this gender convergence, with few exceptions (Greenland, Norway, United Kingdom) boys continued to have a higher frequency of drunkenness in 2005/2006 than girls. The confirmed cultural convergence implies that adoption and implementation of evidence-based measures to mitigate the frequency of adolescent drunkenness such as tax increases and restricting alcohol access and advertisement should get the same priority in Eastern European countries as in Western countries. Policy measures that might facilitate decreases in drunkenness such as server training and the promotion of alcohol-free leisure-time activities should be reinforced in Western countries. The gender convergence implies that prevention policy should be less exclusively focused on male adolescents.

    Ageing of nuclear power plants means evolution of material or equipment properties on one side, and evolution of personnel skill and procedure adequacy on the other side, both of which, after a certain time, may not be compatible with the required safety provisions, or with an economic operation of the plant. Repair or replacement of components, as well as change in service conditions for a better compatibility with component reduced capabilities can be used to mitigate ageing effects. The paper summarises the results of a study conducted in this field with the support of the European Commission. It presents: the synthesis of the work done under international auspices, and in the European context; the comparison of ageing management approaches used in several European countries with international recommendations; the summary of the various potential phenomena and their governing parameters, the methods of in-service ageing identification and possible mitigation methods; illustrative ageing management practices, taking material ageing aspects as examples. Concerning the first topic, the European report identifies 56 OECD and IAEA reports on ageing management issues, 35 being summarised in an appendix to the report. It also identifies numerous European and international studies covering topics of interest to ageing and Plant Life management. ageing management approaches have been considered from the regulatory point of view and from the utilities management point of view. Contributors to the study have identified a general consensus in Europe, with no limited time operating authorisation, the safety being a utility responsibility under continuous surveillance by the regulatory authority. Practical ageing management methods include: periodic safety reviews (PSR), a ten years periodicity being a common practice, completed by continuous ageing management taking into account safety and industrial anticipation needs; the implementation of life-time management programmes

    This study compared the conceptual foci and methodological characteristics of research projects which tested the effects of nursing interventions, published in four general nursing research journals with predominantly North American, and two with predominantly European/International authorship and readership. Dimensions and variables of comparison included: nature of subjects, design issues, statistical methodology, statistical power, and types of interventions and outcomes. Although some differences emerged, the most striking and consistent finding was that there were no statistically significant differences (and thus similarities) in the content foci and methodological parameters of the intervention studies published in both groups of journals. We conclude that European/International and North American nursing intervention studies, as reported in major general nursing research journals, are highly similar in the parameters studied, yet in need of overall improvement. Certainly, there is no empirical support for the common (explicit or implicit) ethnocentric American bias that leadership in nursing intervention research resides with and in the United States of America.

    European precipitation has sustained robust trends during wintertime (January - March) over recent decades. Central, western, and northern Europe have become wetter by an average 0.1-0.3% per annum for the period 1901-2010, while southern Europe, including the Iberian Peninsula, much of Italy and the Balkan States, has sustained drying of -0.2% per annum or more over the same period. The overall pattern is consistent across different observational precipitation products, while the magnitude of the precipitation trends varies amongst data sets. Using cluster analysis, which identifies recurrent states (or regimes) of European winter precipitation by grouping them according to an objective similarity criterion, changes in the frequency of dominant winter precipitation patterns over the past century are evaluated. Considerable multi-decadal variability exists in the frequency of dominant winter precipitation patterns: more recent decades are characterised by significantly fewer winters with anomalous wet conditions over southern, western, and central Europe. In contrast, winters with dry conditions in western and southern Europe, but above-average rainfall in western Scandinavia and the northern British Isles, have been more common recently. We evaluate the associated multi-decadal large-scale circulation changes across the broader extratropical North Atlantic region, which accompany the observed wintertime precipitation variability using the 20th Century reanalysis product. Some influence of the North Atlantic Oscillation (NAO) is apparent in modulating the frequency of dominant precipitation patterns. However, recent trends in the characteristics of atmospheric blocking across the North Atlantic sector indicate a change in the dominant blocking centres (near Greenland, the British Isles, and west of the Iberian Peninsula). Associated changes in sea level pressure, storm track position and strength, and oceanic heat fluxes across the North Atlantic region are also

    This periodic report no. 1 describes the work done in the Danish part of the European Wind Power Integration Study in the period until 1.4.1991. The R and D project was initiated January 1, 1989 upon prior establishment of registration equipment at 7 wind farms and at the Tjaereborg turbine. ELSAM and the meteorological service centre in Karup (VTC-Karup) have supplied data for the task. Wind Predictability, Potential and Benefits, Wind Farm - Grid Interface, Distribution System Strength, Wind Farm Cost and Operation, and Co-generation Wind Turbines/Other renewables were measured and modelled. The statistical distribution of the wind speed variations (changes in wind speed from one period of time to another) has been established with great certainty in the report. The wind speed variations follow a Weibull distribution, irrespective of the time intervals with which the data are considered. Duration curves and power distributions for the 7 wind farms have been estimated. Registration equipment for one-minute measurements was chosen in order to clarify the short-term variations in the wind power production. The possibility of working out production forecasts, to be applied in the daily load dispatching, were to be assessed for the total amount of wind power production in Jutland and Funen. The report has examined whether it would be possible to have only one wind measurement and then let it be `guiding` for the total wind farm production. Some simulations are to be carried out in the attempt to set up guidelines for the connection between the strength of distribution systems and the requirements which must be made to the wind farms which are to be places in the system.

    In this paper different options to connect large solar power plants in North Africa to the European power system are compared from a transmission system investment point of view. Three different possible DC connections from Tunisia to Italy are investigated from a cost-based perspective. In the second part of the paper, the impact of the power fluctuations from CSP and PV power plants on the frequency control is examined in a qualitative manner. It is shown that the frequency response mainly depends on the amount of PV installed and the inertia present in the grid. The results of the simulations give a first estimation of the maximum amount of PV integration in the Tunisian grid without reaching certain frequency limits after a sudden power fluctuation.

    2011-01-01

    On 11 March 2011, the Tohoku region in north Honshu, Japan, suffered a severe earthquake with an ensuing tsunami and an accident at the Fukushima Dai-ichi nuclear power plant. Due to the accident the Council of the European Union declared in late March that Member States were prepared to begin reviewing safety at nuclear facilities in the European Union by means of a comprehensive assessment of risk and safety ('stress testing'). On 25 May, SSM ordered the licensees of the nuclear power plants to conduct renewed analyses of the facilities' resilience against different kinds of natural phenomena. They were also to analyse how the facilities would be capable of dealing with a prolonged loss of electrical power, regardless of cause. On 31 October, the licensees reported on their stress tests to SSM. After reviewing these reports, SSM produced a summary stress test report, which was submitted to the Government on the 15 December. The present report is the national report on Swedish stress tests of nuclear power plants. The report will be submit to the European Commission no later than 31 December. Based on the review SSM has drawn the conclusion that the stress tests carried out by Swedish licensees are largely performed in accordance with the specification resolved within the European Union. The scope and depth of these analyses and assessments are essentially in accordance with ENSREG's definition of 'a comprehensive assessment of risk and safety'. The stress tests show that Swedish facilities are robust, but the tests also identify a number of opportunities to further strengthen the facilities' robustness. SSM will order the respective licensees to present an action plan for dealing with the results from the stress tests. The Authority will then examine the plans and adopt a standpoint on proposed measures as well as check that the necessary safety improvements are made. In a number of cases, the stress tests indicate deficiencies in relation to, or alternatively

    Poland's accession to the European Union contributed to the infrastructure development of the whole country. One of the elements of the modernized infrastructure is the sewage network and facilities on this network, as well as facilities for waste water treatment and disposal of sludge. A wide stream of funds flowing to the country, and consequently also to the north-eastern polish voivodeships (Podlaskie, Warmian-Masurian, Lublin), allowed modernization, organize, and sometimes to build a new sewage management of this part of the country. The main factors and parameters that allow us to evaluate the development of the sewage management in north-eastern Poland are included: percentage of population using sewage treatment plants, number of municipal sewage plants with the division of their type, number of industrial plants, number of septic tanks, amount of sewage purified in a year, amount of sludge produced in the year, design capacity of sewage treatment plant, size of plant in population equivalent (PE). From a number of investments in the field of wastewater management carried out in the discussed area in the period after Poland's accession to the European Union, 9 investments were considered the most important, 3 from each of the voivodeships.

    The most important goal of the Environmental Law is to maximize the prevention approach. As so far, a scheme has been initiated since a few years to reach this objective: a legal environmental process with a lot of mechanisms whose the objective is to estimate the environmental impact of a project in order to control it. This legal environmental process including for example the Environmental Impact Assessment is more and more integrated in the environmental policies of the industrialized countries. It began in North America, first in the U.S.A. but also in Canada. A few years after, the countries of the Western Europe, particularly the European Unions, have introduced a similar legal process taking into account the specificities of these European countries. So if the goals of this legal environmental preventive approach are similar in North America and in Western Europe, the implementation is often different according to the legal, economic but also sociological structures of these two major regions. This Phd Thesis try to study the two major impacts of this legal evaluating process: it is implemented by the public authorities to reach with a best result a Sustainable Development. But also, it tries to combine the protection of the Environment and the utilisation of legal, economic and financial mechanisms of the Market to obtain a fair trade competition. (authors)

    At the past AGU Annual Meeting in 2011, we presented information about development of the recreation industry in European Russia within the "Silver Ring" Project (http://neespi.org/web-content/meetings/AGU_2011/Yakovleva-poster.pdf). This Project can be considered as a system of actions directed to a comprehensive socio-economic development of the Northwest of the Russian Federation that includes 11 provinces ("oblast", "republic", "okrug") of the country. Among the provinces included in the Project, The Komi Republic is one of the most interesting regions. The Komi Republic is located in the North of European Russia within the gridbox restricted by 59N - 69N latitudes and 45E - 66E longitudes. The region is populated by indigenous northern nations: Komi, Russians, Karels, Ved', Permyaks, and others. It is characterized as an ecologically clean territory, has a small population density, is rich with natural reserves, and has abundant forest and water resources. Flora and fauna of the Republic are unique and attractive. Rich biodiversity and abundance of fish and game allow hunting and sport fishing. As of January 1, 2010, The Komi Republic has 240 territories of special environmental protection ("zakazniki") with restricted human activity. This allows a diversity of field trips devoted to in-depth studies of regional ecosystems as well as tourist visits aiming to enjoy unique nature and ethnic-cultures of the North.

  5. Rents in the European power sector due to carbon trading

    2010-01-01

    The European Union Emissions Trading Scheme (EU ETS) has imposed a price on the allowances for CO 2 emissions of electricity companies. Integrating this allowance price into the price of electricity earns a rent for companies who have received these allowances for free. During Phase I, 2005-2007, rents corresponding to the aggregate value of allocated allowances amounted to roughly EUR 13 billion per year. However, due to the specific price-setting mechanism in electricity markets true rents were considerably higher. This is due to the fact that companies also that have not received any allowances gain additional infra-marginal rents to the extent that their variable costs are below the new market price after inclusion of the allowance price. Producers with low carbon emissions and low marginal costs thus also benefit substantially from carbon pricing. This paper develops a methodology to determine the specific interaction of the imposition of such a CO 2 constraint and the price-setting mechanism in the electricity sector under the assumption of marginal cost pricing in a liberalized European electricity market. The article thus provides an empirical estimate of the true total rents of power producers during Phase I of the EU-ETS (2005-2007). The EU ETS generated in Phase I additional rents in excess of EUR 19 billion per year for electricity producers. These transfers are distributed very unevenly between different electricity producers. In a second step, the paper assesses the impact of switching from free allocation to an auctioning of allowances in 2013. We show that such a switch to auctioning will continue to create additional infra-marginal rents for certain producers and will leave the electricity sector as a whole better off than before the introduction of the EU ETS.

    Selenium supplementation and its effects on Northerners have been little studied. The aim of our study was to assess the selenium levels of the inhabitants of North European Russia, the seasonal aspects of selenium supplementation, and the interrelationships between selenium levels and the levels of thyroid gland hormones. To study the particular features of selenium metabolism in Northerners over the course of 1 year, 19 healthy male Caucasian volunteers (18-21 years old) were recruited for the present study. The subjects were military guards in a Northern European region of Russia (Syktyvkar, Russia, 62°N latitude) who spent 6-10-h outdoors daily. The study was conducted over a 12-month period. Selenium levels, glutathione peroxidase (GP) activity, as well as total triiodothyronine (T3), total thyroxin (T4), free thyroxin, free triiodothyronine, and thyrotropin (TSH) levels, were determined in the blood serum. The study subjects showed low levels of plasma selenium throughout the year. We observed a noticeable decrease in plasma selenium levels during the period from May to August, with the lowest levels in July. Selenium levels in the military guards correlated with the levels of selenium-dependent GP enzyme activity throughout the year. Additionally, we demonstrated a significant correlation between selenium and pituitary-thyroid axis hormones (total T3, free T4, and TSH) in periods in which plasma selenium levels were lower than the established normal ranges. Over the course of 1 year, low levels of plasma selenium affect GP activity and thyroid hormone levels in humans living in North European Russia.

  7. Review on the Projections of Future Storminess over the North Atlantic European Region

    Full Text Available This is an overview of the results from previously published climate modeling studies reporting on projected aspects of future storminess over the North Atlantic European region (NAER in the period 2020–2190. Changes in storminess are summarized for seven subregions in the study area and rated by a categorical evaluation scheme that takes into account emission scenarios and modeling complexity in the reviewed studies. Although many of the reviewed studies reported an increase in the intensity of high-impact wind speed and extreme cyclone frequency in the second half of the 21st century, the projections of aspects of future storminess over the NAER differed regionally. There is broad consensus that the frequency and intensity of storms, cyclones, and high-impact wind speed will increase over Central and Western Europe, and these changes will probably have the potential to produce more damage. In contrast, future extratropical storminess over Southern Europe is very likely to decrease. For Northern and Eastern Europe the results of the evaluation are inconclusive, because there is an indication of increasing as well as decreasing development of the evaluated aspects of future storminess. Concerning the storm track, we found indications of a likely north- and eastward shift in most assessed studies. Results from three studies suggest a northeastward shift of the North Atlantic Oscillation.

    To a chief these goals a series of experimental procedure have been executed for the wastewater in sump tank at river side where all wastewater collected. This paper attempts to investigate the chemical and physical characteristics of Khartoum North Power Station waste water and to suggest methods for removing oil before being discharged to River Bule Nile. To achieve this goal numerous numbers of samples have been collected and examined to detect oil content, turbidity, suspended solids, total dissolved solids, pH, BOD, COD and conductivity, and average values of these parameters were 924.3 ppm, 554.2 NTU, 80 ppm, 559.5 ppm, 7.3 pH unit, 130 Pm, 443.14 ppm, 736.7 μs/cm respectively. The average values of these results were compared with [1] guide lines which are 15 ppm, 5 ppm, 60 ppm, <1000 ppm, 7.5 pH unit, 60 ppm, 100 ppm 500 μs/cm respectively. The outcome of the paper confirmed that waste water at Khartoum North Power Station (KNPS) is heavily polluted with oil and other pollutants. For this reason a second phase of experiments is carried out mainly to remove or reduce oil content to 6.7 ppm and other pollutants to levels which may comply with International Regulations and Local Authority acts. The treatment phase of experiment comprising different processing units arranged in a logical sequence starting with units for oil removal through a coagulation process, NaoH ending with air floatation and skimping to reduce oil content. Results obtained from second phase of experiments after waste water being treated are encouraging and a total reduction in contamination of not less than 80% has been achieved. (Author)

    2010-04-01

    There has been a debate in the Netherlands about the compatibility of new investment by individual utilities in the thermal plant park with Government policy to have 12 GW of onshore and offshore wind generation capacity installed by the year 2020. The key areas of concern are: (a) whether sufficient flexibility will exist in the power system to permit uncertain, intermittent wind generation output to be accommodated; and (b) whether the available sources of flexibility will be accessible by relevant market participants. In this context, EnergieNed asked Frontier Economics to carry out a study of the year 2020 for the Dutch and North West European power system. The requirement was to undertake quantitative modelling and qualitative analysis of the system in the year 2020 under a small number of scenarios in order to answer a series of specific questions. Frontier Economics was also asked to look at experience in Denmark and other countries with high wind and combined heat and power plant (CHP) penetration.

It was shown that the conditions of the European North in the absence of anthropogenic pollution failed to affect the number of 14-year-old boys and girls having health groups I, II, III, IV, and V. Anthropogenic pollution was found to decline the number of health group I adolescents living in the European North, without influencing this indicator in those dwelling at mid-latitudes, but, in spite of the latitude of their residence, to increase that of persons with health group II, without having an impact on the number of persons with health groups III, IV, and V.

    To investigate eating disorder psychopathology, restraint and eating concern in young women with and without an eating disorder from two different ethnic groups in Australia and Singapore. The relationship of Eating Disorder Examination Questionnaire Global, Restraint and Eating Concern scores to cultural orientation and sociocultural factors was analysed in 154 women with and without an eating disorder. Participants were from the following backgrounds: North European Australian, East Asian Australian, Singaporean Chinese and North European expatriates in Singapore. Women with eating disorders had similar psychopathology across the cultural groups. Among controls, Singaporean Chinese reported significantly greater overall eating disorder psychopathology than other cultural groups and greater restraint than North European Australians/expatriates. Eating concern was not associated with cultural group overall or acculturation to Western culture. Dissatisfaction with family functioning, socioeconomic status and education level were not significantly associated with any of the eating disorder measures. In eating disorder psychopathology, the specific symptom of eating concern may transcend cultural influences.

    Based on a DLR-study in 1998/99 on behalf of ESA/ESTEC called ''System Concepts, Architectures and Technologies for Space Exploration and Utilization (SE and U)'' a new design for an Earth-orbiting Solar Power Satellite (SPS) has been developed. The design is called ''European Sail Tower SPS'' and consists mainly of deplorable sail-like structures derived from the ongoing DLR/ESA solar sail technology development activity. Such an SPS satellite features an extremely light-weight and large tower-like orbital system and could supply Europe with significant amounts of electrical power generated by photovoltaic cells and subsequently transmitted to earth via microwaves. In order to build up the sail tower, 60 units - each consisting of a pair of square-shaped sails - are moved from LEO to GEO with electric propulsion and successively assembled in GEO robotically on a central strut. Each single sail has dimensions of 150 m x 150 m and is automatically deployed, using four diagonal lightweight carbon fiber (CFRP) booms which are initially rolled up on a central hub. The electric thrusters for the transport to GEO could also be used for orbit and attitude control of the assembled tower which has a total length of about 15 km and would be mainly gravity gradient stabilized. Employing thin film solar cell technology, each sail is used as a solar array and produces an electric power in orbit of about 3.7 MW{sub e}. A microwave antenna with a diameter of 1 km transmits the power to a 10 km rectenna on the ground. The total mass of this 450 MW SPS is about 2100 tons. First estimates indicate that the costs for one kWh delivered in this way could compete with present day energy costs, if launch costs would decrease by two orders of magnitude. Furthermore, mass production and large numbers of installed SPS systems must be assumed in order to lower significantly the production costs and to reduce the influence of the expensive technology

    The European nuclear power industry is being restructured from an industry drawn along national lines to a European-wide industry. This, in part, reflects growth of the European Economic Community, but it also reflects changes in the international nuclear power industry. The objectives of the participants, beyond better integration of the nuclear industry in Western Europe, are to (1) obtain European leadership of the worldwide commercial nuclear power industry, (2) improve medium- and long-term safety of Eastern Europe and the former Soviet Union (FSU) power reactors, and (3) reduce domestic concerns about nuclear power. The activities to achieve these goals include (1) formation of Nuclear Power International (a joint venture of the German and French nuclear power plant vendors for design and construction of nuclear power plants), (2) formation of a utility group to forge agreement throughout Europe on what the requirements are for the next generation of nuclear power plants, and (3) agreement by regulators in multiple European countries to harmonize regulations. This is to be achieved before the end of the decade. These changes would allow a single design of nuclear power plant to be built anywhere in Europe. The creation of European-wide rules (utility requirements, engineering standards, and national regulations) would create strong economic and political forces for other European countries (Eastern Europe and FSU) to meet these standards.

    We study time-zero efficiency of electricity derivatives markets. By time-zero efficiency is meant a sequence of prices of derivatives contracts having the same underlying asset but different times to maturity which implies that prices comply with a set of efficiency conditions that prevent profitable time-zero arbitrage opportunities. We investigate whether statistical tests, based on the law of one price, and trading rules, based on price differentials and no-arbitrage violations, are useful for assessing time-zero efficiency. We apply tests and trading rules to daily data of three European power markets: Germany, France and Spain. In the case of the German market, after considering liquidity availability and transaction costs, results are not inconsistent with time-zero efficiency. However, in the case of the French and Spanish markets, limitations in liquidity and representativeness are challenges that prevent definite conclusions. Liquidity in French and Spanish markets should improve by using pricing and marketing incentives. These incentives should attract more participants into the electricity derivatives exchanges and should encourage them to settle OTC trades in clearinghouses. Publication of statistics on prices, volumes and open interest per type of participant should be promoted. - Highlights: •We test time-zero efficiency of derivatives power markets in Germany, France and Spain. •Prices in Germany, considering liquidity and transaction costs, are time-zero efficient. •In France and Spain, limitations in liquidity and representativeness prevent conclusions. •Liquidity in France and Spain should improve by using pricing and marketing incentives. •Incentives attract participants to exchanges and encourage them to settle OTC trades in clearinghouses.

  16. Influence of the North Atlantic Oscillation on European tropospheric composition: an observational and modelling study

    Pope, R.; Chipperfield, M.

    2017-12-01

    The North Atlantic Oscillation (NAO) has a strong influence on winter-time North Atlantic and European circulation patterns. Under the positive phase of the NAO (NAO+), intensification of the climatological Icelandic low and Azores high pressure systems results in strong westerly flow across the Atlantic into Europe. Under the NAO negative phase (NAO-), there is a weakening of this meridional pressure gradient resulting in a southerly shift in the westerlies flow towards the sub-tropical Atlantic. Therefore, NAO+ and NAO- introduce unstable stormy and drier stable conditions into Europe, respectively. Under NAO+ conditions, the strong westerlies tend to enhance transport of European pollution (e.g. nitrogen oxides) away from anthropogenic source regions. While during NAO-, the more stable conditions lead to a build up of pollutants. However, secondary pollutants (i.e. tropospheric ozone) show the opposite signal where NAO+, while transporting primary pollutants away, introduces Atlantic ozone enriched air into Europe. Here ozone can form downwind of pollution from continental North America and be transported into Europe via the westerly flow. Under NAO-, this westerly ozone transport is reduced yielding lower European ozone concentrations also depleted further by ozone loss through the reaction with NOx, which has accumulated over the continent. Peroxyacetyl nitrate (PAN), observed in the upper troposphere - lower stratosphere (UTLS) by satellite, peaks over Iceland/Southern Greenland in NAO-, between 200-100 hPa, consistent with trapping by an anticyclone at this altitude. During NAO+, PAN is enhanced over the sub-tropical Atlantic and Arctic. Model simulations show that enhanced PAN over Iceland/Southern Greenland in NAO- is associated with vertical transport from the troposphere into the UTLS, while peak Arctic PAN in NAO+ is its accumulation given the strong northerly meridional transport in the UTLS.

    1987-01-01

    This paper describes a characterization of the solid radwaste generated at Virginia Power's North Anna and Surry power stations. The primary focus of this characterization was dry active waste (DAW). The characterization, covering the 21-month period from January 1985 through September 1986, was based on information in the station's health physics procurement records, radwaste shipping records, and from interviews with station personnel. The procurement records were the principal source of information for DAW. They were reviewed to determine the quantities of various materials, purchased during the study period, that were expected to become DAW. This provides an upper limit on the quantity in the waste for several major DAW components and a basis for the total amount of other components in the waste. The approach to characterizing DAW discussed in this paper could be implemented and regularly updated by utilizing a computerized procurement records system. If a use code (i.e., contaminated or noncontaminated) is associated with each stock requisition, a characterization could be performed by a computer run. This approach would help track minimization effort effectiveness and would refine the characterization of DAW considerably

    One key to the impact of deregulation being transmitted to residential customers is the successful formation of aggregation groups and their expansion to include different classes of customers with convergent usage interests. This activity currently is being sponsored not only by for-profit brokerage entities, but also by associations of not-for-profit corporations such as hospitals and universities and by countries. The issues presented fall into several categories. (1) Technical rate taking--feasibility of making appropriate arrangements for alternative supply to consumers on a basis which appropriately reflects customer characteristics and also confers benefit on them all; (2) Legal--Compatibility of proposed arrangements with FERC wholesale regulation under Order No. 888 and emerging state regulation under the different restructuring regimes which their state utility commissions are implementing; (3) Marketing/Sociopolitical--Utilization of modern marketing techniques to effect the political consensus which is a precursor of alternative aggregation arrangements; (4) Financing--identification of capital costs; techniques for financing such costs, including monetization of the savings to be realized. The presentation will extrapolate the potential future significance of aggregation as a force in both restructuring and the development of merchant power projects. It will also assess the extent to which institutional, legal, technical or financial factors may modify the ultimate significance of aggression in the North American Power Industry

    With an objective to save energies and reduce global warming gas emission, a feasibility study was performed on the oil burning thermal power plant in the city of North Bangkok in Thailand to reconstruct the plant into a natural gas burning combined cycle power plant. In the project, the old facilities with an output of 237.8 MW using three steam turbines in total will be reconstructed into a plant comprising of two steam turbines for 256,2 MW and two gas turbines for 460.4 MW, or a facility of 716.6 MW in total. The plant construction will have the gas turbines, steam turbines, generators, and a waste heat recovered steam generator fixed on one axis, two of which will be installed. The gas turbines will use natural gas as fuel, and the steam turbines will be operated by steam from the waste heat recovered steam generator. As a result of the discussions, the reduction of the energy consumption for a period of 40 years will correspond to crude oil of 20,560 kt, while the reduction of the global warming gas emission will be 107,200 t-CO2. In addition, the energy saving cost will be 9-ton crude oil equivalent/one million yen, and the cost for reduction of the global warming gas emission will be 47 t-CO2/one million yen. (NEDO)

  1. The future profile of power generation in North America

    Eynon, R.T.

    2004-01-01

    This presentation addressed North American power generation issues with particular reference to energy markets, electricity projections, coal supply and natural gas supply. Energy demand is expected to grow due to an increase in population and economic activity. Growth will be tempered by improvements in energy efficiency of equipment and buildings. Production of domestic energy is projected to grow, but not enough to meet energy demands in the United States, thereby increasing levels of imports, primarily natural gas from Canada. One of the key factors in energy markets is the price of natural gas which rose to record levels in 2001 due to strong demand in the winter and tight supplies stemming from low drilling rates in the late 1990s. In the long term, technology improvements will offset price increases. Improvements in gas finding and development technology will continue. Electricity use is projected to grow at slightly slower than historical rates due to improvements in equipment efficiency and investments in demand-side management programs. The growth in electricity sales is led by the commercial sector followed by the industrial sector. The paper emphasized the need for new generating capacity to replace aging generating plants. Coal-fired steam plants have the largest share of power generation in the United States, representing about one-half of total generation, followed by nuclear, natural gas and renewable energy sources. The use of petroleum for generation is small and is expected to decline in the future with the advent of new efficient generating technologies. The use of natural gas for power generation is expected grow significantly due to new technologies for efficient combustion turbines and combined-cycle generators fueled by natural gas. These technologies have low capital costs compared to other technologies and have short lead times for construction. tabs., figs

    Full Text Available Mapping and assessing the ecosystem services provided by benthic habitats are a highly valuable source of information for understanding their current and potential benefits to society. The main objective of this investigation is to assess and map the ecosystem services provided by benthic habitats of the European North Atlantic Ocean, in the context of Mapping and Assessment of Ecosystems and their Services (MAES programme, the European Biodiversity Strategy and the implementation of the Marine Strategy Framework Directive. In total, 62 habitats have been analysed in relation to 12 ecosystem services over 1.7 million km2. Results indicated that more than 90% of the mapped area provides biodiversity maintenance and food provision services; meanwhile grounds providing reproduction and nursery services are limited to half of the mapped area. Benthic habitats generally provide more services closer to shore than offshore and in shallower waters. This gradient is likely to be explained by difficult access (i.e. distance and depth and lack of scientific knowledge for most of the services provided by distant benthic habitats. This research has provided a first assessment of the benthic ecosystem services at Atlantic European scale, with the provision of ecosystem services maps and their general spatial distribution patterns. Related to the objectives of this research, the conclusions are: (i benthic habitats provide a diverse set of ecosystem services, being the food provision and biodiversity maintenance services the ones that are more extensively represented. In addition, other regulating and cultural services are provided in a more limited area; and (ii the ecosystem services assessment categories are significantly related to the distance to the coast and with depth (higher near the coast and in shallow waters.

  3. Renewable energy and CCS in German and European power sector decarbonization scenarios

    Ludig, Sylvie

    2013-11-06

    system costs are lower when transmission and storage are available. Restrictions on transmission expansion induce high amounts of storage since high local shares of solar PV lead to large output variations. In contrast, a highly interconnected European power grid allows for optimized renewable power generation siting in regions with highest potentials, which requires large-scale transmission expansions but limits total power system costs. Results from a detailed study for Germany show that the level of power demand is strongly relevant for the realization of high renewable shares and ambitious decarbonization targets. A broad technology portfolio allows to hedge against the failure to meet efficiency goals for electricity demand. CCS is necessary to reach ambitious government targets if power demand is not sufficiently decreased by efficiency measures, as is offshore wind energy. Even in case of decreasing demand, at least one of both technologies needs to be available. The choice of transmission expansion corridors is strongly influenced by technology availability: in scenarios without offshore wind energy, north-south interconnections, which are crucial in all other scenarios, only play a minor role. The studies in this thesis show that a large-scale decarbonization of the German and European power sectors is achievable through large shares of renewable energy technologies for electricity generation. CCS is not a prerequisite for successful CO{sub 2} emission strategies, but allows reaching mitigation targets at a lower cost. A portfolio of renewable energy integration options is essential to manage temporal and spatial fluctuations; the optimal technology mix is determined by the underlying power system.

    1992-01-01

    The electric utilities of North America have become ever more interconnected via transmission facilities, largely to insure reliability. Current policy discussions regarding transmission include calls for improved access, increased capacity, and deregulation to facilitate trade in electric power. From an environmental perspective, two issues have been notably absent in much of the debate: (1) a recognition of the full range of environmental impacts related to electricity transmission; and (2) the potential for end-use efficiency to address the reliability and economy requirements that motivate attention to transmission. This paper broaches these issues, starting with an elaboration of the environmental impacts, which range from global and regional effects to local concerns, including the potential health risks associated with electric and magnetic fields. We emphasize that transmission planning should occur as part of an integrated planning process, in which the environmental and social costs of various options are fully considered. We discuss the potential for end-use efficiency to lessen environmental impacts of both transmission and generation. We conclude that there is a need to ensure that environmental externalities and demand-side alternatives are adequately considered when transmission network expansions are proposed. (Author)

  7. Access pricing on gas networks and capacity release markets: Lessons from North American and European experiences

    David, L.; Percebois, J.

    2004-01-01

    An evaluation of different access fee systems in North America and Europe in relation to normative prices is discussed. Among available alternatives the entry-exit pricing system as it is currently applied in the United Kingdom, the Netherlands, Italy and France, was judged to be the best solution to increased competition. Canadian and American experiences highlight the influence of the market power of shippers with regard to the efficacy of capping the market. Whether or not to cap the price on a capacity release market is a choice between the protection of shippers against market abuses and the promotion of secondary market liquidity, a choice that is linked to the level of congestion of a pipeline system. If there is much congestion, a price cap may be necessary; if there is little congestion, the need for market value given by an uncapped price may be more important than the market power of shippers. 15 refs., 2 tabs

    This paper seeks to explore the extent to which the corporate realignments which have occurred in the North American Natural Gas Industry during a now relatively lengthy experience with liberalization involving a large number of players, will be imitated in the future by European Union countries other than the UK (which is of course already long-embarked along the path of Anglo-Saxon liberalization). The paper first of all catalogues the North American experience, drawing on company performance data assembled by the authors over the last decade (Rutledge and Wright, 1993, 1995, 1997, 1999, 2000). Secondly, this empirical exploration gives way to theoretical speculation: are there elements of the North American experience for which explanatory generalizations are possible? Thirdly, these empirical and theoretical insights are employed to identify and explore actual and potential differences in the corporate evolution of the European Union natural gas industry.

    Full Text Available Integration is one of the main consequences of globalization. Elements of microsystems are growing closer, which brings to the foreground problems of interaction and — in a longer perspective — those of close cooperation between different social systems. The article considers the case of North-West Russia, the only territory having a common border with the EU, in order to examine the issue of Russia using the geographical factor, which Otto von Bismarck called the most powerful and intrinsic factor in history. The significance of this factor increased after the Cold War. It was then when the independent Baltic States became a platform for emergence and recognition of the Baltic Sea region. The author focuses on the social and cultural integrity of the region and considers the traditional Nordic countries and the Baltic Sea states as interrelated components of a single region, different from other European regions in terms of economic interests, as well as its natural and sociocultural landscape.

    Jones, R.; Taylor, J.; Santucci, J.

    1996-01-01

    The structure of the US utility industry is in transition. Political, social, and economic factors are contributing to a rapid shift from a monopoly structure (captive markets, cost-plus prices, negotiated rate of return on capital) to a highly competitive one (choices for customers, prices determined by the market place, earnings based on market price less cost). The rate of change has been accelerating. For example, what just two years ago would have been thought of as highly unlikely -- competition for the individual electric customer -- is now part of the plan in California and other states. In our view, technology is at the root of many of these structural changes with more to come. Yet another round of technological change is afoot, involving even more efficient gas turbines, new methods of utilizing transmission lines, distributed generation, and new opportunities for electricity use and service. It can be argued that the restructuring of the marketplace reflects, in some measure, anticipation for these advances. For the foreseeable future, nuclear energy will continue to play a significant role in the generating grid of North America. However, new nuclear generation will be held to standards of competition that are dictated by market forces, and by advances in competing technologies for base load generation. It is important to understand these forces, and devise a response which ensures that nuclear energy will continue to provide a viable, competitive, and environmentally superior option for generating electricity in the 21st century. The EPRI Nuclear Power program is focused on achieving these goals. (author)

    Recent studies have presented conflicting results regarding the 11 year solar cycle (SC) influences on winter climate over the North Atlantic/European region. Analyses of only the most recent decades suggest a synchronized North Atlantic Oscillation (NAO)-like response pattern to the SC. Analyses of long-term climate data sets dating back to the late 19th century, however, suggest a mean sea level pressure (mslp) response that lags the SC by 2-4 years in the southern node of the NAO (i.e. Azores region). To understand the conflicting nature and cause of these time dependencies in the SC surface response, the present study employs a lead/lag multi-linear regression technique with a sliding window of 44 years over the period 1751-2016. Results confirm previous analyses, in which the average response for the whole time period features a statistically significant 2-4 year lagged mslp response centered over the Azores region. Overall, the lagged nature of Azores mslp response is generally consistent in time. Stronger and statistically significant SC signals tend to appear in the periods when the SC forcing amplitudes are relatively larger. Individual month analysis indicates the consistent lagged response in December-January-February average arises primarily from early winter months (i.e. December and January), which has been associated with ocean feedback processes that involve reinforcement by anomalies from the previous winter. Additional analysis suggests that the synchronous NAO-like response in recent decades arises primarily from late winter (February), possibly reflecting a result of strong internal noise.

    The edge of the North West European Shelf (NWES) is characterised by a steep continental slope and a northward flowing slope current. These topographic/hydrographic features separate oceanic water and shelf water masses hence potentially separate phytoplankton communities. The slope current may facilitate the advective transport of phytoplankton, with mixing at the shelf edge supporting nutrient supply and therefore phytoplankton production. On the west Scottish shelf in particular, little is known about the phytoplankton communities in and around the shelf break and adjacent waters. Hence, to improve our understanding of environmental drivers of phytoplankton communities, biological and environmental data were collected on seven cross-shelf transects across the Malin and Hebridean Shelves during autumn 2014. Density profiles indicated that shelf break and oceanic stations had a 100 m deep mixed surface layer while stations on the shelf were generally well mixed. Analysis of similarity and multidimensional scaling of phytoplankton counts revealed that phytoplankton communities on the shelf were significantly different to those found at the shelf break and at oceanic stations. Shelf stations were dominated by dinoflagellates, with diatoms contributing a maximum of 37% of cells. Shelf break and oceanic stations were also dinoflagellate dominated but displayed a lower species diversity. Significant difference between shelf and shelf break stations suggested that the continental slope limited cross shelf phytoplankton exchange. Northern and southern phytoplankton communities on the shelf were approximately 15% dissimilar while there was no latitudinal gradient for stations along the slope current, suggesting this current provided south to north connectivity. Fitting environmental data to phytoplankton ordination showed a significant relationship between phytoplankton community dissimilarities and nutrient concentrations and light availability on the shelf compared to

    In recent years, many countries have implemented policies to incentivize renewable power generation. This paper outlines the effects of weather uncertainty on investment and operation decisions of electricity producers under a feed-in tariff and renewable quota obligation. Furthermore, this paper tries to quantify the sectoral welfare and investments risks under the different policies. For this purpose, a spatial stochastic equilibrium model is introduced for the European electricity market. The numerical analysis suggests that including the electricity market price in renewable policies (wholesale price + x) reduces the loss of sectoral welfare due to a renewable policy by 11-20 %. Moreover, investors face an only slightly higher risk than under fixed price compensations. However, electricity producers face a substantially larger investment risk when introducing a renewable quota obligation without the option of banking and borrowing of green certificates. Given the scenario results, an integration of the hourly market price in renewable support mechanisms is mandatory to keep the financial burden to electricity consumers at a minimum. Additionally, following the discussion of a European renewable quota after 2020, the analysis indicates the importance of an appropriate banking and borrowing mechanism in light of stochastic wind and solar generation.

    The European energy sector is currently facing a new set of challenges in the light of the COP21 Paris agreement, the Energy Union initiative and new market design projections. Nuclear energy sector understands the post COP21 constellation as a unique opportunity for all low carbon technologies which will be basic for transition towards COP21 commitments. A new policy outlook for Europe is needed in order to provide low carbon capacity, lead to the modernisation of technical processes and contribute to the prosperity of Europeans. The benefits of nuclear are highlighted for a low carbon future and for the security of supply and recommend actions for supporting new investments.

    We need more rather than less money for research, energy research in particular, research being an important contributor to progress, in order to achieve peak performance, comply with the quest for knowledge about the structure of the world, or to be able to further improve our quality of life at far less expense of materials and energy. This latter concept is in line with European identity. If we succeed in demonstrating to the world that people can live a better life if they manage their affairs sustainably, we Europeans will have won a new trademark: a sustainable Europe which can be left to future generations. For this purpose Europeans, more than before, must perceive Europe as a space of knowledge. Science policy must be geared to Europe, not just to a national territory. Also, Europe should devote more attention to fundamental research. Some outstanding projects are needed, particularly in energy research, with the participation of industry in order to reduce materials consumption and avoid emissions. Education, too, must be given much attention. In the absence of enthusiastic young scientists, engineers, and skilled workers who know their neighboring countries and their technologies and languages from an early age, European energy policy is bound to remain fragmented.

    Phenological sensitivity of plants strongly depends on regional climate variability, moreover it is also influenced by large-scale atmospheric circulation patterns. Plants in different environmental conditions (determined by geographical latitude and longitude, altitude, continentality) may show diverse responses to climate change. The first results of an international cooperation aiming at the analysis of plant phenological data along a latitudinal gradient over 12 European countries (Macedonia, Bosnia and Herzegovina, Montenegro, Slovenia, Croatia, Hungary, Slovakia, Poland, Lithuania, Latvia, Estonia and Finland) are presented. The spatio-temporal changes in the flowering onset dates of common lilac (Syringa vulgaris L.) during the period of 1970-2000 were analysed. To characterise the environmental conditions driving the phenological responses, climatic variables (atmospheric pressure, air temperature, precipitation) obtained from a gridded observational dataset (E-OBS 9.0) and time series of the North Atlantic Oscillation (NAO) index were used. Preliminary results for this particular species found a gradual advance of mean flowering onsets along latitudes from 40° N to 65° N, at the rate of -0.12 to -0.32 day/year. Significant zonal differences were found in these rates, which can be explained by the sensitivity of flowering to climatic conditions while moving from Mediterranen to boreal regions of Europe. Thus our results were coherent with most observations in the literature, that higher latitudes can exhibit more pronounced responses, particularly in case of spring phenological events.

    Domestic dogs have an ancient origin and a long history in Africa. Nevertheless, the timing and sources of their introduction into Africa remain enigmatic. Herein, we analyse variation in mitochondrial DNA (mtDNA) D-loop sequences from 345 Nigerian and 37 Kenyan village dogs plus 1530 published sequences of dogs from other parts of Africa, Europe and West Asia. All Kenyan dogs can be assigned to one of three haplogroups (matrilines; clades): A, B, and C, while Nigerian dogs can be assigned to one of four haplogroups A, B, C, and D. None of the African dogs exhibits a matrilineal contribution from the African wolf (Canis lupus lupaster). The genetic signal of a recent demographic expansion is detected in Nigerian dogs from West Africa. The analyses of mitochondrial genomes reveal a maternal genetic link between modern West African and North European dogs indicated by sub-haplogroup D1 (but not the entire haplogroup D) coalescing around 12,000 years ago. Incorporating molecular anthropological evidence, we propose that sub-haplogroup D1 in West African dogs could be traced back to the late-glacial dispersals, potentially associated with human hunter-gatherer migration from southwestern Europe.

  3. Spatial patterns of North Atlantic Oscillation influence on mass balance variability of European glaciers

    2012-06-01

    Full Text Available We present and validate a set of minimal models of glacier mass balance variability. The most skillful model is then applied to reconstruct 7735 individual time series of mass balance variability for all glaciers in the European Alps and Scandinavia. Subsequently, we investigate the influence of atmospheric variability associated with the North Atlantic Oscillation (NAO on the glaciers' mass balances.

    We find a spatial coherence in the glaciers' sensitivity to NAO forcing which is caused by regionally similar mechanisms relating the NAO forcing to the mass balance: in southwestern Scandinavia, winter precipitation causes a correlation of mass balances with the NAO. In northern Scandinavia, temperature anomalies outside the core winter season cause an anti-correlation between NAO and mass balances. In the western Alps, both temperature and winter precipitation anomalies lead to a weak anti-correlation of mass balances with the NAO, while in the eastern Alps, the influences of winter precipitation and temperature anomalies tend to cancel each other, and only on the southern side a slight anti-correlation of mass balances with the NAO prevails.

    Full Text Available Indigenous Peoples of North America have collectively used approximately 1800 different native species of plants, algae, lichens and fungi as food. When European explorers, traders and settlers arrived on the continent, these native foods, often identified and offered by Indigenous hosts, gave them sustenance and in some cases saved them from starvation. Over the years, some of these species – particularly various types of berries, such as blueberries and cranberries (Vaccinium spp., wild raspberries and blackberries (Rubus spp., and wild strawberries (Fragaria spp., and various types of nuts (Corylus spp., Carya spp., Juglans spp., Pinus spp., along with wild-rice (Zizania spp. and maple syrup (from Acer saccharum – became more widely adopted and remain in use to the present day. Some of these and some other species were used in plant breeding programs, as germplasm for hybridization programs, or to strengthen a crop's resistance to disease. At the same time, many nutritious Indigenous foods fell out of use among Indigenous Peoples themselves, and along with their lessened use came a loss of associated knowledge and cultural identity. Today, for a variety of reasons, from improving people's health and regaining their cultural heritage, to enhancing dietary diversity and enjoyment of diverse foods, some of the species that have dwindled in their use have been “rediscovered” by Indigenous and non-Indigenous Peoples, and indications are that their benefits to humanity will continue into the future.

  5. Variability of the North Atlantic summer storm track: mechanisms and impacts on European climate

    2013-01-01

    The summertime variability of the extratropical storm track over the Atlantic sector and its links to European climate have been analysed for the period 1948–2011 using observations and reanalyses. The main results are as follows. (1) The dominant mode of the summer storm track density variability is characterized by a meridional shift of the storm track between two distinct paths and is related to a bimodal distribution in the climatology for this region. It is also closely related to the Summer North Atlantic Oscillation (SNAO). (2) A southward shift is associated with a downstream extension of the storm track and a decrease in blocking frequency over the UK and northwestern Europe. (3) The southward shift is associated with enhanced precipitation over the UK and northwestern Europe and decreased precipitation over southern Europe (contrary to the behaviour in winter). (4) There are strong ocean–atmosphere interactions related to the dominant mode of storm track variability. The atmosphere forces the ocean through anomalous surface fluxes and Ekman currents, but there is also some evidence consistent with an ocean influence on the atmosphere, and that coupled ocean–atmosphere feedbacks might play a role. The ocean influence on the atmosphere may be particularly important on decadal timescales, related to the Atlantic Multidecadal Oscillation (AMO). (letter)

    The goal of this project is to apply the WPA’s proactive outreach strategy to the problem of educating the public about the likely transmission infrastructure developments concomitant to the significant development of wind energy resources in North Carolina. Given the lead time to develop significant new transmission infrastructure (5-10 years), it is critical to begin this outreach work today, so that wind resources can be developed to adequately meet the 20% by 2030 goal in the mid- to long-term (10-20 years). The project team planned to develop a transmission infrastructure outreach campaign for North Carolina by: (1) convening a utility interest group (UIG) of the North Carolina Wind Working Group (NC WWG) consisting of electric utilities in the state and the Southeast; and (2) expanding outreach to local and state government officials in North Carolina.

    2010-01-01

    A key motive for establishing the European Food Safety Authority (EFSA) was restoring public confidence in the wake of multiplying food scares and the BSE crisis. Scholars, however, have paid little attention to the actual political and institutional logics that shaped this new organization. This article explores the dynamics underpinning the making of EFSA. We examine the way in which learning and power shaped its organizational architecture. It is demonstrated that the lessons drawn from the past and other models converged on the need to delegate authority to an external agency, but diverged on its mandate, concretely whether or not EFSA should assume risk management responsibilities. In this situation of competitive learning, power and procedural politics conditioned the mandate granted to EFSA. The European Commission, the European Parliament and the European Council shared a common interest in preventing the delegation of regulatory powers to an independent EU agency in food safety policy.

    The North American natural gas industry's experience with deregulation is described, with emphasis on the transition to competition and the conditions for viability under open access. Lessons learned from the North American experience are then examined for relevance to the European situation, which is emphasizing greater access to transmission systems. It is found likely that the European proposal will frequently operate only to facilitate negotiations among players already active in the gas market, and is less likely to introduce a large number of independent transactions or new merchants. Challenges for the system will include: government assurance of reliability to domestic gas users who have made arrangements with foreign suppliers; administration of pipeline grids; resolution of competing claims on available transmission services; planning for future suppliers; and impact on investment. 8 refs., 1 fig

  11. Exploring the meteorological potential for planning a high performance European electricity super-grid: optimal power capacity distribution among countries

    2017-11-01

    The concept of a European super-grid for electricity presents clear advantages for a reliable and affordable renewable power production (photovoltaics and wind). Based on the mean-variance portfolio optimization analysis, we explore optimal scenarios for the allocation of new renewable capacity at national level in order to provide to energy decision-makers guidance about which regions should be mostly targeted to either maximize total production or reduce its day-to-day variability. The results show that the existing distribution of renewable generation capacity across Europe is far from optimal: i.e. a ‘better’ spatial distribution of resources could have been achieved with either a ~31% increase in mean power supply (for the same level of day-to-day variability) or a ~37.5% reduction in day-to-day variability (for the same level of mean productivity). Careful planning of additional increments in renewable capacity at the European level could, however, act to significantly ameliorate this deficiency. The choice of where to deploy resources depends, however, on the objective being pursued—if the goal is to maximize average output, then new capacity is best allocated in the countries with highest resources, whereas investment in additional capacity in a north/south dipole pattern across Europe would act to most reduce daily variations and thus decrease the day-to-day volatility of renewable power supply.

    Several factors are affecting power generating facilities, such as the opening of both electricity and gas markets, and the pressure applied on generators and governments to ensure a steady energy supply for consumers. An additional factor is the pressure for the closing of nuclear power facilities. European siting and emissions requirements for coal-fired and natural gas generating facilities were presented in this background paper. In addition, the author provided an overview of the standardization process in place in Europe. The European Union and its functioning were briefly described, as well as a listing of relevant organizations. The current trends were examined. The document first introduced the European Union, and the next section dealt with Regulatory regime: the internal energy market. The third section examined the issue of Regulatory regime: generation and environmental regulations. Section four presented environmental management systems, followed by a section on standardization. Section six discussed European organizations involved in electricity issues, while the following section dealt with European commission programs. The last section briefly looked at the trends in the electricity sector, broaching topics such as compliance, electricity generation, and emissions trading. 52 refs., 2 tabs

  15. The link between eddy-driven jet variability and weather regimes in the North Atlantic-European sector

    2017-12-01

    Understanding the variability of the North Atlantic eddy-driven jet is key to unravelling the dynamics, predictability and climate change response of extratropical weather in the region. This study aims to 1) reconcile two perspectives on wintertime variability in the North Atlantic-European sector and 2) clarify their link to atmospheric blocking. Two common views of wintertime variability in the North Atlantic are the zonal-mean framework comprising three preferred locations of the eddy-driven jet (southern, central, northern), and the weather regime framework comprising four classical North Atlantic-European regimes (Atlantic ridge AR, zonal ZO, European/Scandinavian blocking BL, Greenland anticyclone GA). We use a k-means clustering algorithm to characterize the two-dimensional variability of the eddy-driven jet stream, defined by the lower tropospheric zonal wind in the ERA-Interim reanalysis. The first three clusters capture the central jet and northern jet, along with a new mixed jet configuration; a fourth cluster is needed to recover the southern jet. The mixed cluster represents a split or strongly tilted jet, neither of which is well described in the zonal-mean framework, and has a persistence of about one week, similar to the other clusters. Connections between the preferred jet locations and weather regimes are corroborated - southern to GA, central to ZO, and northern to AR. In addition, the new mixed cluster is found to be linked to European/Scandinavian blocking, whose relation to the eddy-driven jet was previously unclear. The results highlight the necessity of bridging from weather to climate scales for a deeper understanding of atmospheric circulation variability.

    Phytoplankton underpin the marine food web in shelf seas, with some species having properties that are harmful to human health and coastal aquaculture. Pressures such as climate change and anthropogenic nutrient input are hypothesized to influence phytoplankton community composition and distribution. Yet the primary environmental drivers in shelf seas are poorly understood. To begin to address this in North Western European waters, the phytoplankton community composition was assessed in light of measured physical and chemical drivers during the "Ellett Line" cruise of autumn 2001 across the Scottish Continental shelf and into adjacent open Atlantic waters. Spatial variability existed in both phytoplankton and environmental conditions, with clear differences not only between on and off shelf stations but also between different on shelf locations. Temperature/salinity plots demonstrated different water masses existed in the region. In turn, principal component analysis (PCA), of the measured environmental conditions (temperature, salinity, water density and inorganic nutrient concentrations) clearly discriminated between shelf and oceanic stations on the basis of DIN:DSi ratio that was correlated with both salinity and temperature. Discrimination between shelf stations was also related to this ratio, but also the concentration of DIN and DSi. The phytoplankton community was diatom dominated, with multidimensional scaling (MDS) demonstrating spatial variability in its composition. Redundancy analysis (RDA) was used to investigate the link between environment and the phytoplankton community. This demonstrated a significant relationship between community composition and water mass as indexed by salinity (whole community), and both salinity and DIN:DSi (diatoms alone). Diatoms of the Pseudo-nitzschia seriata group occurred at densities potentially harmful to shellfish aquaculture, with the potential for toxicity being elevated by the likelihood of DSi limitation of

    Full Text Available European wolves (Canis lupus show population genetic structure in the absence of geographic barriers, and across relatively short distances for this highly mobile species. Additional information on the location of and divergence between population clusters is required, particularly because wolves are currently recolonizing parts of Europe. We evaluated genetic structure in 177 wolves from 11 countries using over 67K single nucleotide polymorphism (SNP loci. The results supported previous findings of an isolated Italian population with lower genetic diversity than that observed across other areas of Europe. Wolves from the remaining countries were primarily structured in a north-south axis, with Croatia, Bulgaria, and Greece (Dinaric-Balkan differentiated from northcentral wolves that included individuals from Finland, Latvia, Belarus, Poland and Russia. Carpathian Mountain wolves in central Europe had genotypes intermediate between those identified in northcentral Europe and the Dinaric-Balkan cluster. Overall, individual genotypes from northcentral Europe suggested high levels of admixture. We observed high diversity within Belarus, with wolves from western and northern Belarus representing the two most differentiated groups within northcentral Europe. Our results support the presence of at least three major clusters (Italy, Carpathians, Dinaric-Balkan in southern and central Europe. Individuals from Croatia also appeared differentiated from wolves in Greece and Bulgaria. Expansion from glacial refugia, adaptation to local environments, and human-related factors such as landscape fragmentation and frequent killing of wolves in some areas may have contributed to the observed patterns. Our findings can help inform conservation management of these apex predators and the ecosystems of which they are part.

    Benthic zones of shallow shelf seas receive high amounts of organic material. Physical processes such as resuspension, as well as complex transformations mediated by diverse faunal and microbial communities, define fate of this material, which can be returned to the water column, reworked within sediments or ultimately buried. In recent years, numerical models of various complexity and serving different goals have been developed and applied in order to better understand and predict dynamics of benthic processes. ERSEM includes explicit parameterisations of several groups of benthic biota, which makes it particularly applicable for studies of benthic biodiversity, biological interactions within sediments and benthic-pelagic coupling. To assess model skill in reproducing temporal (inter-annual and seasonal) dynamics of major benthic macrofaunal groups, 1D model simulation results were compared with data from the Western Channel Observatory (WCO) benthic survey. The benthic model was forced with organic matter deposition rates inferred from observed phytoplankton abundance and model parameters were subsequently recalibrated. Based on model results and WCO data comparison, deposit-feeders exert clear seasonal variability, while for suspension-feeders inter-annual variability is more pronounced. Spatial distribution of benthic fauna was investigated using results of a full-scale NEMO-ERSEM hindcast simulation of the North-West European Shelf Seas area, covering the period of 1981-2014. Results suggest close relationship between spatial distribution of biomass of benthic faunal functional groups in relation to bathymetry, hydrodynamic conditions and organic matter supply. Our work highlights that it is feasible to construct, implement and validate models that explicitly include functional groups of benthic macrofauna. Moreover, the modelling approach delivers detailed information on benthic biogeochemistry and food-web at spatial and temporal scales that are unavailable

  8. The development of the northern European fishery for north Atlantic bluefin tuna Thunnus thynnus during 1900-1950

    North Atlantic bluefin tuna, Thunnus thynnus, used to migrate to northern European waters (Norwegian Sea, North Sea, Skagerrak, Kattegat, and Øresund) where it supported important commercial and sportfisheries. The species disappeared from the region in the early 1960s and the species is now still...... increasing. The species was frequently sighted while fishermen were targeting other species (herring, mackerel) and occasionally was caught as bycatch with these and other species. Information from scientifically trained observers demonstrate that tuna schools were common in the North Sea for 2–3 months...... during the summers of 1923–1931. As fishermen realized that the species had market value, new catch methods were developed and employed. These included harpoon-rifle, improved hook and line methods, and hydraulically operated purse seines. Landings rose sharply as did the number of vessels...

    Dominant European winter precipitation patterns over the past century, along with their associated extratropical North Atlantic circulation changes, are evaluated using cluster analysis. Contrary to the four regimes traditionally identified based on daily wintertime atmospheric circulation patterns, five distinct seasonal precipitation regimes are detected here. Recurrent precipitation patterns in each regime are linked to changes in atmospheric blocking, storm track, and sea surface temperatures across the North Atlantic region. Multidecadal variability in the frequency of the precipitation patterns reveals more (fewer) winters with wet conditions in northern (southern) Europe in recent decades and an emerging distinct pattern of enhanced wintertime precipitation over the northern British Isles. This pattern has become unusually common since the 1980s and is associated with changes in moisture transport and more frequent atmospheric river events. The observed precipitation changes post-1950 coincide with changes in storm track activity over the central/eastern North Atlantic toward the northern British Isles.

  10. Finacial Expertise, Authority and Power in the European Football 'Industry'

    Directory of Open Access Journals (Sweden)

    Hertbert F. Moorhouse

    2007-12-01

    Full Text Available The paper aims to provoke discussion about two issues. Firstly, how do economic ideas, concepts, theories, principles and information enter into the discourse of the owners and controllers of Europe’s most popular sport – football – and into political discussion about the game? It stresses the role management consultants have created for themselves in the new football 'industry'. Secondly, as a specific example of the general concern, the paper considers the role of the Deloitte company in European football. Its publications – especially the Annual Reviews of Football Finance – have been very influential and the company has acted as consultants for UEFA on many of the key issues in contemporary football. The paper critically assesses the approach Deloitte has adopted to the commercialisation of football, and explores difficulties in the way it has analysed some of the key issues in European football. It suggests that some countervailing forces need to be created to limit the authority and influence Deloitte currently exercise.

    Report about Operation, Construction, and Planning in 18 European Countries Eighteen European countries operate and build, respectively, nuclear power plants in 1995. The ''Nuclear Power Plants in Europe 1995'' atw report singles out the main events and lines of development. As per August 1995, 214 (1994: 215) nuclear generating units (which means power reactors for the purposes of this report) with an aggregate 177,010 (176,322) MWe installed gross capacity are in operation in seventeen countries, and 26 (30) units with 24,786 (28,086) MWe are under construction in seven countries. This adds up to a total of 240 (245) nuclear generating units with an aggregate 201,796 (204,408) MWe. In the nuclear power plants in Europe, some 1048 TWh of nuclear power was converted into electric power in 1994; 792 TWh of this aggregate was converted in 137 units in the European Union (EU). In the EU the share of nuclear power in the public supply of electricity was 36%. Lithuania, with 77%, has the highest share of nuclear power in Europe, followed by France with 75% and Belgium with 56%. The lowest percentage, only 5%, is recorded in the Netherlands. As a consequence of electricity imports, nuclear power holds considerable shares in the public electricity supply also of countries in which no nuclear power plants are operated, such as Italy or Austria.

  12. The role of power sources in the European electricity mix

    2017-01-01

    Full Text Available The ongoing debate in Europe about energy transition enhances the necessity to evaluate the performance of the envisaged mix of power sources, in terms of production cost, CO2 emissions and security of supply. In this study, we use MIXOPTIM, a Monte-Carlo simulator of the behavior of a mix of power sources on a territory, to evaluate the performance of the present EU power mix. After a validation on the French mix, we applied it to the whole EU territory and made variational calculations around the present mix to evaluate the performance impacts induced by small changes in installed renewable power and nuclear power. According to the analyzed criteria, the study shows that a plausible way to keep an affordable MWh in Europe with minimal amount of CO2 emissions and acceptable security of supply could be to extend the life of existing Gen II nuclear reactors. All other options lead to the degradation of the mix performance, on at least one of the three criteria listed above.

    2012-01-01

    In response to the Fukushima-Daiichi accident, the European Council laid down the requirement that a transparent and comprehensive risk assessment exercise ('stress tests') be carried out at each European nuclear power plant. The stress tests concentrated on the nuclear power plants' safety margins in the light of the lessons learned from the accident. The reviews focused on natural external events including earthquake, tsunami and extreme weather, loss of safety functions, and severe accident management. The stress test procedure comprised 3 steps: (i) The nuclear facility operators performed the stress tests and prepared proposals for safety improvements. (ii) The national regulators performed independent reviews of the stress tests and prepared national reports. (iii) The reports submitted by the national regulators were subjected to review at a European level. The article describes the scope of the stress tests and their results, verified at the European level. (orig.)

    Behind electrical systems, we should not forget the human networks. The European case is interesting for that matter. There were major players involved, from the pioneers up to the conceivers of national and international systems. More particularly, the engineers should be considered for their technical as well as organizational performance. Attitudes must also be stressed: in Europe, electricity has constantly been developed with both nationalist and internationalist considerations, as shown by the passage from Unternehmergeschaeft to Bankgeschaeft after 1918. Neither should we forget the role played by institutions in the formation of networks: schools, holdings, cartels, and also those frontier zones formed by small countries like Belgium and Switzerland. The human networks, finally, left long term results such as: interconnection, inter-firm cooperation, technocracy, and the growing intervention of the State

    As a power outage affected several millions European people in November 2006, this article identifies and discusses actions to be implemented at the European level to avoid such a situation and thus strengthen energy security for all European citizen. It proposes a detailed analysis of the situation of electricity transport grids before the incident, of what happened in terms of overloads for some very high voltage lines: the de-energizing of a line over the Ems River resulted in a domino triggering off of very high voltage lines connected to different areas of Europe; a decrease of current frequency resulted in the disconnection of power plants and grid managers had to reduce consumption in emergency. The article draws some early lessons of the incident before the UCTE (Power Transport Coordination Union) inquiry, and recommends some actions regarding grid coordination, harmonisation of abilities and decisions, and performance of provisional assessments of the electricity supply/demand balance

    Southern Europe, on the edge of the sunbelt, represents the ideal location for solar thermal generated power. Last year. SAWIE reported on the THESEUS project, a proposed 50 MWe solar thermal power plant for Frangokastello, southern Crete, which was submitted for support under the European Union`s THERMIE Programme. Funding was approved for the design phase for this innovative power plant, the first large-scale SEGS-style plant on European soil, at the end of last year. However, the THERMIE Programme also provided support for another Southern European plant, proposed by Colon Solar for Huelva in Southern Spain. Whilst hurdles remain to be overcome before both plants are built and commissioned, there is an excellent chance that by the start of the new Millennium, the solar collectors from these two plants could be generating over half a million MWh of energy a year. SAWIE compares the two projects. (author)

    2011-01-01

    For prevention of reactor accidents of nuclear power plants, multiplicity and redundancy of emergency power would be most important. At station blackout accident, European type manually operated vent operation could minimize release amount of radioactive materials and keep safety of neighboring residents. After Fukushima Daiichi accident, nuclear power plants could not restart operation even after completion of periodical inspection. This article introduced European type emergency power and vent systems in Swiss, Sweden and Germany with state of nuclear power phaseout for reference at considering to upgrade safety and accident mitigation measures for better understanding of the public. In addition, it would be important to recover trust of nuclear technology to continue to disseminate latest information on new knowledge of accident site and decontamination technologies to domestic and overseas people. As its implementation, establishment of Fukushima international center was proposed. (T. Tanaka)

    The first Euroatom European nuclear conference was held in Brussels on November 25/26, 2004 was attended by more than 250 renowned experts, including more than 20 managers of the board from a dozen European countries. They all agreed that the construction of new nuclear power plants will depend on the public opinion, i.e. it will be a political and communication problem rather than a technical problem. A swing of public opinion is difficult as rational arguments do not apply when emotions are high. The economic efficiency of nuclear power was proved again by the new reactor constructed in Finland.

    2009-01-01

    The aim of this study is to estimate the C loss from forest soils due to the production of dissolved organic C (DOC) along a north-south European transect. Dissolved organic matter (DOM) was extracted from the forest soils incubated at a controlled temperature and water content. Soils were sampled from forest plots from Sweden to Italy. The plots represent monocultures of spruce, pine and beech and three selected chronosequences of spruce and beech spanning a range of mean annual temperature from 2 to 14 deg. C. The DOM was characterized by its DOC/DON ratio and the C isotope composition δ 13 C. The DOC/DON ratio of DOM varied from 25 to 15 after 16 days of incubation and it decreased to between 16 and 10 after 126 days. At the beginning of incubation the δ 13 C values of DOC were 1 per mille or 2 per mille less negative than incubated soils. At the end of the experiment δ 13 C of DOC were the same as soil values. In addition to DOC production heterotrophic respiration and N mineralization were measured on the incubated soils. The DON production rates decreased from 30 to 5 μgN gC -1 d -1 after 16 days of incubation to constant values from 5 to 2 μgN gC -1 d -1 after 126 days at the end of experiment. The DIN production rates were nearly constant during the experiments with values ranging from 20 to 4 μgN gC -1 d -1 . DOC production followed first-order reaction kinetics and heterotrophic respiration followed zero-order reaction kinetics. Kinetic analysis of the experimental data yielded mean annual DOC and respiration productions with respect to sites. Mean annual estimates of DOC flux varied from 3 to 29 g of C m -2 (1-19 mg C g -1 of available C), corresponding to mean DOC concentrations from 2 to 85 mg C L -1 .

  3. Power for all? Electricity and uneven development in North Carolina

    Science.gov (United States)

    Harrison, Conor M.

    Many towns in eastern North Carolina face a number of challenges common to the rural South, including high rates of poverty and diminishing employment opportunities. However, some residents of this region also confront a unique hardship---electricity prices that are vastly higher than those of surrounding areas. This dissertation examines the origins of pricing inequalities in the electricity market of eastern North Carolina---namely how such inequalities developed and their role in the production of racial and economic disparities in the South. This dissertation examines the evolving relations between federal and state agencies, corporations, and electric utilities, and asks why these interactions produced varying social outcomes across different places and spatial settings. The research focuses on the origins and subsequent development of electric utilities in eastern North Carolina, and examines how electricity as a material technology interacted with geographies of race and class, as well as the dictates of capital accumulation. This approach enables a rethinking of several concepts that are rarely examined by scholars of electric utilities, most notably the monopoly service territory, which I argue served as a spatial fix to accumulation problems in the industry. Further, examining the way that electric utilities developed in North Carolina during the 20th century brings to the forefront the at times contradictory relationships among systems of electricity provision, Jim Crow segregation, the Progressive Era, and the New Deal. Such a focus highlights the important role that the control of electricity provision played in shaping racial inequalities that continue to persist in the region. With most urban areas were electrified in the 1930s, the research also traces the electricity distribution lines as they moved out of cities through rural electrification programs, a shift that highlights the state as a multi-scalar and variegated actor that both aided and

    2015-04-01

    The penetration of renewable energies in the European power system has increased in the last decades (23.5% share of renewables in the gross electricity consumption of the EU-28 in 2012) and is expected to increase further up to very high shares close to 100%. Planning and organizing this European energy transition towards sustainable power sources will be one of the major challenges of the 21st century. It is very likely that in a fully renewable European power system wind and photovoltaics (pv) will contribute the largest shares to the generation mix followed by hydro power. However, feed-in from wind and pv is due to the weather dependant nature of their resources fluctuating and non-controllable. To match generation and consumption several solutions and their combinations were proposed like very high backup-capacities of conventional power generation (e.g. fossile or nuclear), storages or the extension of the transmission grid. Apart from those options hydro power can be used to counterbalance fluctuating wind and pv generation to some extent. In this work we investigate the effects of hydro power from Norway and Sweden on residual storage needs in Europe depending on the overlaying grid scenario. High temporally and spatially resolved weather data with a spatial resolution of 7 x 7 km and a temporal resolution of 1 hour was used to model the feed-in from wind and pv for 34 investigated European countries for the years 2003-2012. Inflow into hydro storages and generation by run-of-river power plants were computed from ERA-Interim reanalysis runoff data at a spatial resolution of 0.75° x 0.75° and a daily temporal resolution. Power flows in a simplified transmission grid connecting the 34 European countries were modelled minimizing dissipation using a DC-flow approximation. Previous work has shown that hydro power, namely in Norway and Sweden, can reduce storage needs in a renewable European power system by a large extent. A 15% share of hydro power in Europe

    Recently, concerns about the atmospheric environmental problems in North Korea (NK) have been growing. According to the World Health Organization (WHO) (2017), NK was the first ranked country in mortality rate attributed to household and ambient air pollution in 2012. Reliable energy-related data in NK were needed to understand the characteristics of air quality in NK. However, data from the North Korean government were limited. Nevertheless, we could find specific energy-related data produced by NK in the Project Design Documents (PDDs) of the Clean Development Mechanism (CDM) submitted to the United Nations Framework Convention on Climate Change (UNFCCC). There were the 6 registered CDM projects hosted by North Korea, developed as small hydropower plants. Several data of each power plant, such as the electricity output, connected to the Eastern Power Grid (EPG) or the Western Power Grid (WPG) in North Korea were provided in the CDM PDDs. We (1) figured out the trends of the electricity output, the `power conversion efficiency' which we defined the amount of generated electricity to the supplied input primary energy for power generation, and fuel mix as grid emission factor in NK as using the data produced by NK between 2005 and 2009, (2) discussed the operating status of the thermal power plants in NK, and (3) discussed the energy/environmental-related policies and the priority issues in NK in this study.

    Rock and pop stars are frequently characterised as indulging in high-risk behaviours, with high-profile deaths amongst such musicians creating an impression of premature mortality. However, studies to date have not quantified differences between mortality experienced by such stars and general populations. This study measures survival rates of famous musicians (n = 1064) from their point of fame and compares them to matched general populations in North America and Europe. We describe and utilise a novel actuarial survival methodology which allows quantification of excess post-fame mortality in pop stars. Individuals from North America and Europe performing on any album in the All-Time Top 1000 albums from the music genres rock, punk, rap, R&B, electronica and new age. From 3 to 25 years post fame, both North American and European pop stars experience significantly higher mortality (more than 1.7 times) than demographically matched populations in the USA and UK, respectively. After 25 years of fame, relative mortality in European (but not North American) pop stars begins to return to population levels. Five-year post-fame survival rates suggest differential mortality between stars and general populations was greater in those reaching fame before 1980. Pop stars can suffer high levels of stress in environments where alcohol and drugs are widely available, leading to health-damaging risk behaviour. However, their behaviour can also influence would-be stars and devoted fans. Collaborations between health and music industries should focus on improving both pop star health and their image as role models to wider populations.

  18. The European Commission: nuclear power has an important role to play

    International Nuclear Information System (INIS)

    2008-01-01

    The European Commission (E.C.) thinks that nuclear power has an important role to play: first to reduce CO 2 emissions and secondly to reinforce energy self-reliance of the member states. The decision to introduce nuclear power in their energy mix belongs to every state but the E.C. has also highlighted that if adequate investment are quickly made 2 thirds of the electricity produced in the European Union in 2010 could by from low-carbon-emitting sources. Today with 148 reactors operating in 15 member countries nuclear power contributes to 1 third of the electricity produced. Another issue that is looming is the security of electricity supplying. A study has shown that the security level is worsening (particularly in winter) because of the greater part of wind energy in the energy mix as wind energy is not necessarily available when energy demand is peaking. The E.C. has proposed a new directive drawing a common standard frame for nuclear safety requirements concerning design, site selection, maintenance, operation and decommissioning of nuclear facilities. Each member state will have the choice to implement stiffer regulations. The European Union must reduce its dependency on Russian gas by increasing its storing capacities, by easing gas exchanges between member states and by importing more liquefied natural gas. European member states will have to invert 1000*10 9 euros in gas and electrical power infrastructures in the next 25 years. (A.C.)

    This paper describes the results of a study on characterization of the major constituents of the solid radwaste generated at Virginia Power's North Anna and Surry Power Stations. The characterization consisted of identifying the individual constituents of the dry active waste (DAW) and estimating the fraction of the total DAW (both weight and volume) made up by each constituent. The analysis of the characterization of solid waste streams generated at both North Anna and Surry stations has lead to recommending techniques for both source minimization and waste volume reduction

  3. The European Commission in the power relations of the European Union after the 2004–07 enlargement

    2014-05-01

    Full Text Available pplying a comparative perspective, this article argues that the current crisis of European Union integration cannot be resolved by member states either transferring additional competences to the EU level or strengthening the intergovernmental dimension of integration. The systemic character of the ongoing process is weakening the institutional structure, which affects both the institutions and their power relations. The European Commission (EC, once a highly independent supranational actor on the eve of the integration process in the 1950s, now faces growing competition from intergovernmental elements in the institutional balance. The theoretical approach of historical neo-institutionalism offers new, useful insights into this research area. The articles uses this theory to analyze the EC’s evolution since the time of its creation in the form of the High Authority of the European Coal and Steel Community, focusing on the links between the gradual changes in its internal structure and its institutional position. Although the phenomenon of “path dependence” was initially present in the EC’s internal systems, the later development of its competences in the institutional balance provoked member states to limit the commission’s activities in the second half of the 1960s. First attempts were made mainly by appointing weak presidents, but the later reform of the EC’s internal structure, undertaken by Neil Kinnock in the beginning of the 21st centry, directed its further structural development as a more technocratic institution. Consequently, the EC was not able to pursue its aims effectively in preparing for its enlargement to include Central and Eastern Europe. The increased heterogeneity of the member states after the 2004–07 enlargement also weakened the EC’s position in the institutional balance, diminishing its traditional function as the “engine of integration.”

    2012-01-01

    Through a parametric time-series analysis of 8 years of hourly data, we quantify the storage size and balancing energy needs for highly and fully renewable European power systems for different levels and mixes of wind and solar energy. By applying a dispatch strategy that minimizes the balancing energy needs for a given storage size, the interplay between storage and balancing is quantified, providing a hard upper limit on their synergy. An efficient but relatively small storage reduces balancing energy needs significantly due to its influence on intra-day mismatches. Furthermore, we show that combined with a low-efficiency hydrogen storage and a level of balancing equal to what is today provided by storage lakes, it is sufficient to meet the European electricity demand in a fully renewable power system where the average power generation from combined wind and solar exceeds the demand by only a few percent. - Highlights: ► We model a wind and solar based European power system with storage and balancing. ► We find that storage needs peaks when average renewable generation matches load. ► We find strong synergetic effects when combining storage and balancing. ► We study the effects of a storage capable of storing 6 h average use. ► We find a realisable fully renewable scenario based on wind, solar and hydro power.

    In a jointly adopted communique in August 1992 the regulations governing the partnerships were laid down. The following principles are given priority: bilateral exchange of operating experience on the basis of equal partnership; the knowledge gained from the exchange of experience is used to improve the operation and safety of the respective partner plant; the partnership programme is free from commercial interests and does not include transfer of funds. Since the establishment of the first partnership relations (Biblis) with an east european nuclear power plant (Balakowo) late in April 1990, a total of 126 reciprocal visits was paid, 82 of which to German nuclear power plants. The balance of the efforts made by German nuclear power plant operators to integrate east european nuclear plant operators can be considered positive. (orig./HP) [de

    2014-10-01

    Full Text Available We establish that the European Union is facing severe ecological problems, by analysing the ecological footprint of selected member states. Many of these problems are related to carbon and carbon equivalent emissions, some of which are generated by fossil fuel power plants. It is then shown that the European Union has potential in the solar power renewable energy sector. Finally, we calculate roughly how much land would be necessary in order to replace fossil fuel power plants, as well as nuclear plants, which are largely seen as environmentally dangerous. It is concluded that developing this alternative energy sector would help improve the ecological sustainability of the Union, by diminishing a significant part of its carbon footprint.

    Balmer, M.; Spreng, D.; Moest, D.

    2006-01-01

    This article takes a look at a number of questions in relation to the future use of Swiss hydropower that are neither clear nor unchallenged. Questions concerning the replacement or refurbishment of hydropower schemes that will have to be renewed in the next few years are asked. Also, developments in the European power market are looked at. The future influence of wind power, trading with CO 2 certificates, increases in the price of gas etc. are examined. An analysis of the competitiveness of Swiss hydropower with reference to the European power supply system that was made by the Centre for Energy Policy and Economics CEPE at the Swiss Federal Institute of Technology ETH is described. The 'Perseus'-model developed by CEPE and the Industrial Technology Institute at the University of Karlsruhe in Germany is used to analyse possible developments over the period up to 2030. The results are presented in graphical form and commented on

  9. Functional Resilience against Climate-Driven Extinctions - Comparing the Functional Diversity of European and North American Tree Floras.

    Directory of Open Access Journals (Sweden)

    Mario Liebergesell

    Full Text Available Future global change scenarios predict a dramatic loss of biodiversity for many regions in the world, potentially reducing the resistance and resilience of ecosystem functions. Once before, during Plio-Pleistocene glaciations, harsher climatic conditions in Europe as compared to North America led to a more depauperate tree flora. Here we hypothesize that this climate driven species loss has also reduced functional diversity in Europe as compared to North America. We used variation in 26 traits for 154 North American and 66 European tree species and grid-based co-occurrences derived from distribution maps to compare functional diversity patterns of the two continents. First, we identified similar regions with respect to contemporary climate in the temperate zone of North America and Europe. Second, we compared the functional diversity of both continents and for the climatically similar sub-regions using the functional dispersion-index (FDis and the functional richness index (FRic. Third, we accounted in these comparisons for grid-scale differences in species richness, and, fourth, investigated the associated trait spaces using dimensionality reduction. For gymnosperms we find similar functional diversity on both continents, whereas for angiosperms functional diversity is significantly greater in Europe than in North America. These results are consistent across different scales, for climatically similar regions and considering species richness patterns. We decomposed these differences in trait space occupation into differences in functional diversity vs. differences in functional identity. We show that climate-driven species loss on a continental scale might be decoupled from or at least not linearly related to changes in functional diversity. This might be important when analyzing the effects of climate-driven biodiversity change on ecosystem functioning.

    Bronze birch borer (Agrilus anxius Gory) is the key pest of birches (Betula spp.) in North America, several of which have been recommended for ornamental landscapes based on anecdotal reports of borer resistance that had not been confirmed experimentally. In a 20-yr common garden experiment initiated in 1979 in Ohio, North American birch species, including paper birch (Betula papyrifera Marshall), 'Whitespire' gray birch (Betula populifolia Marshall), and river birch (Betula nigra L.), were much more resistant to bronze birch borer than species indigenous to Europe and Asia, including European white birch (Betula pendula Roth), downy birch (Betula pubescens Ehrh.), monarch birch (Betula maximowicziana Regel), and Szechuan white birch (Betula szechuanica Jansson). Within 8 yr of planting, every European white, downy, and Szechuan birch had been colonized and killed, although 100% of monarch birch had been colonized and 88% of these plants were killed after nine years. Conversely, 97% of river birch, 76% of paper birch, and 73% Whitespire gray birch were alive 20 yr after planting, and river birch showed no evidence of colonization. This pattern is consistent with biogeographic theory of plant defense: North American birch species that share a coevolutionary history with bronze birch borer were much more resistant than naïve hosts endemic to Europe and Asia, possibly by virtue of evolution of targeted defenses. This information suggests that if bronze birch borer were introduced to Europe or Asia, it could threaten its hosts there on a continental scale. This study also exposed limitations of anecdotal observation as evidence of host plant resistance.

    2008-09-01

    Glass eel catches and FAO (Food and Agricultural Organization) landings of the European freshwater eel (Anguilla anguilla) show a decrease over the past 20 years. The long-term trends in the time series mask an interannual fluctuation, which becomes apparent on the application of a high-pass filter and autocorrelation analysis. Both the FAO landings and the glass eel catches show interannual fluctuations with a repeat period of 6-8 years, similar to the period of the North Atlantic Oscillation (NAO). Most glass eel catch monitoring stations are in phase. The glass eel catches show a significant negative correlation with the NAO lagged by 0-2 years, consistent with the hypothesis that the positive NAO phase has an adverse impact on the larval survival in and migration from the Sargasso Sea spawning location, one year prior to the arrival of the glass eels in Europe and North Africa. The FAO landings can be divided into two groups of different phase that have an approximate correspondence to the NAO dipole in winter rainfall in Europe and North Africa. One group (P) comprises Denmark, Ireland, Morocco, Netherlands, Norway, Sweden, Tunisia, and the United Kingdom, and the other group (N) comprises France, Germany, Italy, Poland, Portugal, Spain, and Turkey. At least for the interannual fluctuations, the success of the glass eel fishery (and eel recruitment) may be coupled with the number of migrating silver eels from the N group of countries and uncoupled with the P group of countries.

    This paper describes the next-generation ocean forecast model for the European north-west shelf, which will become the basis of operational forecasts in 2018. This new system will provide a step change in resolution and therefore our ability to represent small-scale processes. The new model has a resolution of 1.5 km compared with a grid spacing of 7 km in the current operational system. AMM15 (Atlantic Margin Model, 1.5 km) is introduced as a new regional configuration of NEMO v3.6. Here we describe the technical details behind this configuration, with modifications appropriate for the new high-resolution domain. Results from a 30-year non-assimilative run using the AMM15 domain demonstrate the ability of this model to represent the mean state and variability of the region.Overall, there is an improvement in the representation of the mean state across the region, suggesting similar improvements may be seen in the future operational system. However, the reduction in seasonal bias is greater off-shelf than on-shelf. In the North Sea, biases are largely unchanged. Since there has been no change to the vertical resolution or parameterization schemes, performance improvements are not expected in regions where stratification is dominated by vertical processes rather than advection. This highlights the fact that increased horizontal resolution will not lead to domain-wide improvements. Further work is needed to target bias reduction across the north-west shelf region.

  16. The strategic role of power grids in the implementation of a European energy policy

    2010-01-01

    With the development of low carbon and renewable energies, the World is living a third energy revolution. In this new context, the European Union has adopted an ambitious energy policy with a triple objective: reducing the volume of carbon dioxide emissions in the atmosphere in order to fight against a possible disastrous climatic change, increasing the security of its energy supplies by limiting its fossil fuels dependence and by reinforcing the solidarity between member states in particular during crisis situation, and completing the building up of domestic electricity and gas markets by a better integration of these markets at the European scale and in relation with neighboring areas (Mediterranean region, Russia). This article explains the key of success of such a policy: a prominent part of electricity in the European energy mix, with a strategic role given to power grids

    2011-01-01

    This paper investigates the impact of the economic recession on CO 2 emissions in the European power sector, during the years 2008 and 2009. Three main determinants of the power sector's emissions are identified: the demand for electricity, the CO 2 price, and fuel prices. A counterfactual scenario has been set up for each of these, i.e., what these parameters would have been if not affected by the recession. A simulation model of the European power sector is then employed, comparing a historical reference simulation (taking the parameters as actually occurred) with the counterfactual scenarios. The lower electricity demand (due to the recession) is shown to have by far the largest impact, accounting for an emission reduction of about 175 Mton. The lower CO 2 price (due to the recession) resulted in an increase in emissions by about 30 Mton. The impact of fuel prices is more difficult to retrieve; an indicative reduction of about 17 Mton is obtained, mainly as a consequence of the low gas prices in 2009. The simulated combined impact of the parameters results in an emission reduction of about 150 Mton in the European power sector over the years 2008 and 2009 as a consequence of the recession. - Research highlights: → CO 2 emissions are simulated for the European power sector. → Emissions reduced drastically because of the economic recession in 2008 and 2009. → Lower electricity demand had highest impact and accounts for reduction of about 175 Mton. → Impact of different CO 2 and fuel prices on emissions is more limited.

    Jaureguy-Naudin, Maite

    2012-01-01

    Europe's energy policy is commonly defined by three axes of equal importance: security of supplies, competitiveness and sustainable development. The European Commission is mandated to develop the policy tools that allow the implementation of this common policy. Early on, challenges arose from the trade-offs to be made not only between these three pillars but also between a common European policy and national approaches. The European Commission has always had to struggle in attempting to keep a balanced line. Over the past twenty years, the EU has been engaged in the liberalization of the electricity and gas sector. For a long time, liberalization was the main objective of European energy policy. Liberalization of the electricity sector was supposed to bring many benefits. Foremost, these included the more efficient allocation of generation and transmission capacities, and the enhancement of the competitiveness of the European economy as a whole, through lower energy costs. The trading of electricity output between countries was part of this strategy. Interconnections are vital to facilitating electricity trade between Member States. It is in this context that interest in cross-border interconnections has increased. However, new constraints have emerged and have put climate change at the top of European agenda. In December 2008, as part of the fight against climate change, the European Union adopted its Energy and Climate package endorsing three objectives for 2020: i) a 20% increase in energy efficiency, ii) a 20% reduction in GHG emissions (compared to 1990), and iii) a 20% share of renewable energy sources in final energy consumption. A direct consequence of the later objective is that renewable energy sources (RES) in electricity generation are expected to expand from 20.3% of electricity output in 2010, to around 33%, in order to meet the objective set by the European Commission. Hydroelectric power has limited additional potential due to geographical

  4. Economic analysis of the cross-border coordination of operation in the European power system

    International Nuclear Information System (INIS)

    Janssen, Tanguy

    2014-01-01

    The electricity high voltage transmission networks are interconnected over most of the continents but this is not the case of the power system organizations. Indeed, as described with the concept of integrated power system, the organization over these large networks is divided by several kinds of internal borders. In this context, the research object, the cross-border coordination of operation, is a set of coordination arrangements over internal borders between differing regulatory, technical and market designs. These arrangements can include for instance the famous market couplings, some cost-sharing agreements or common security assessments among several other solutions. The existence and improvement of the cross-border coordination of operation can be beneficial to the whole integrated power system. This statement is verified in the European case as in 2012 where several regional and continental coordination arrangements are successfully implemented.In order to benefit from the European experience and contribute to support the European improvement process, this thesis investigates the cross-border coordination of operation in the European case with four angles of study. First, a modular framework is built to describe the existing solutions and the implementation choices from a regulatory point of view. Second, the thesis analyses the tools available to assess the impact of an evolution of the cross-border coordination. Third, the role of the European Union (EU) is described as critical both for the existing arrangements and to support the improvement process. The last angle of study focuses on two dimensions of the economic modes of coordination between transmission system operators. (author)

    1993-01-01

    The original steam generators at Virginia Electric and Power Company's (Virginia Power) North Anna Power Station (NAPS) Unit 1 have experienced corrosion-related degradation that require periodic inspection and plugging of steam generator tubes to ensure their continued safe and reliable operation. Despite improvements in secondary water chemistry, continued tube degradation in the steam generators necessitated the removal from service of approximately 20.3 percent of the tubes by plugging, (18.6, 17.3, and 25.1 for steam generators A, B, and C, respectively). Additionally, the unit power was limited to 95 % during, its last cycle of operation. Projections of industry and Virginia Power experience indicated the possibility of mid-cycle inspections and reductions in unit power. Therefore, economic considerations led to the decision to repair the steam generators (i.e., replace the steam generator lower assemblies). Three new Model 51F Steam Generator lower assembly units were ordered from Westinghouse. Virginia Power contracted Bechtel Power Corporation to provide the engineering and construction support to repair the Unit 1 steam generators. On January 4, 1993, after an extended coastdown period, North Anna Unit 1 was brought off-line and the 110 day (breaker-to-breaker) Steam Generator Replacement Project (SGRP) outage began. As of this paper, the outage is still in progress

    Westinghouse Electric Company has provided a number of Chemistry On-Line Monitoring (OLM) Systems to Nuclear Power Plants in Eastern Europe. Eleven systems were provided to the Temelin Nuclear Power Plant in the south of the Czech Republic. Four systems were provided to the Russian NPP at Novovoronezh. In addition, a system design was developed for primary side chemistry monitoring for units 5 and 6 of another eastern European VVER. The status of the Temelin OLM systems is discussed including updates to the Temelin designs, and the other Eastern European installations and designs are also described briefly. Some of the problems encountered and lessons learned from these projects are also discussed. (R.P.)

    Full Text Available Recent crises show clearly that Europeans security depends on external developments. The Common Security and Defense Policy failed to provide security, while the European Union military missions were limited in terms of their scope. This inability threatens the interests and security of the member states. Exactly, this research explores the concept of military power of the EU. In order to elaborate anatomy of military power of the EU, the descriptive-analytic method is used. Military performance analysis proves that the EU is able to have the greatest impact in the global arena. The research shows that with the achievement of a political strategy among the stakeholder, on which the replacement of the consensus mechanism with an ordinary majority is predicted, the EU would be able to lead a proactive and efficient security policy.

    A cost-minimizing electricity market model was used to explore optimized infrastructures for the integration of renewable energies in interconnected North African power systems until 2030. The results show that the five countries Morocco, Algeria, Tunisia, Libya and Egypt could together achieve significant economic benefits, reaching up to €3.4 billion, if they increase power system integration, build interconnectors and cooperate on joint utilization of their generation assets. Net electricity exports out of North Africa to Europe or Eastern Mediterranean regions, however, were not observed in the regime of integrated electricity markets until 2030, and could only be realized by much higher levels of renewable energy penetration than currently foreseen by North African governments. - Highlights: • Market model to optimize North Africa's generation and transmission infrastructures until 2030. • Simulations consider existing interconnectors, power plant inventories, as well as national renewable goals. • Savings of up to €3.4 billion can be realized by more cooperation and integrated system planning. • No electricity exports to Europe in a competitive market framework, except for very high renewable penetrations

    The low technological standard of nuclear power plants in East Europe is a matter of concern. NPP operators are in a bad financial situation as they often are compelled to sell their electricity below cost price, or payment increasingly is delayed, or not coming in at all. Special EU programmes and partnership agreements with West European electricity companies have been instigated in order to lead out of the crisis. Will they remain no more than a pebble dropped into the sea? (orig.) [de

    2006-01-01

    This paper develops a static computational game theoretic model. Illustrative results for the liberalising European electricity market are given to demonstrate the type of economic and environmental results that can be generated with the model. The model is empirically calibrated to eight Northwestern European countries, namely Belgium, Denmark, Finland, France, Germany, The Netherlands, Norway, and Sweden. Different market structures are compared, depending on the ability of firms to exercise market power, ranging from perfect competition without market power to strategic competition where large firms exercise market power. In addition, a market power reduction policy is studied where the near-monopolies in France and Belgium are demerged into smaller firms. To analyse environmental impacts, a fixed greenhouse gas emission reduction target is introduced under different market structures. The results indicate that the effects of liberalisation depend on the resulting market structure, but that a reduction in market power of large producers may be beneficial for both the consumer (i.e. lower prices) and the environment (i.e. lower greenhouse gas permit price and lower acidifying and smog emissions)

    The North West European Shelf break acts as a barrier to the transport and exchange between the open ocean and the shelf seas. The strong spatial variability of these exchange processes is hard to fully explore using observations, and simulations generally are too coarse to simulate the fine-scale processes over the whole region. In this context, under the FASTNEt program, a new NEMO configuration of the North West European Shelf and Atlantic Margin at 1/60° (˜1.8 km) has been developed, with the objective to better understand and quantify the seasonal and interannual variability of shelf break processes. The capability of this configuration to reproduce the seasonal cycle in SST, the barotropic tide, and fine-resolution temperature profiles is assessed against a basin-scale (1/12°, ˜9 km) configuration and a standard regional configuration (7 km resolution). The seasonal cycle is well reproduced in all configurations though the fine-resolution allows the simulation of smaller scale processes. Time series of temperature at various locations on the shelf show the presence of internal waves with a strong spatiotemporal variability. Spectral analysis of the internal waves reveals peaks at the diurnal, semidiurnal, inertial, and quarter-diurnal bands, which are only realistically reproduced in the new configuration. Tidally induced pycnocline variability is diagnosed in the model and shown to vary with the spring neap cycle with mean displacement amplitudes in excess of 2 m for 30% of the stratified domain. With sufficiently fine resolution, internal tides are shown to be generated at numerous bathymetric features resulting in a complex pycnocline displacement superposition pattern.

    Full Text Available The article presents the results of studies of the spatial development qualities and the human capital expanded reproduction of the Republic of Karelia and the Arctic regions of Russia’s European North. The aim of the article is the identification of characteristics, opportunities and threats of human capital reproduction in terms of region spatial development. The application of the research results is to provide recommendations for improving reproduction of the human capital and development of the education and vocational guidance systems, human capital management in the region. The study of spatial development and reproduction of the human capital used methods of logical, statistical and comparative analysis and SWOT- analysis principles. The results of the study allowed revealing the peculiarities of spatial development and human capital expanded reproduction of the Republic of Karelia in comparison with the Russian Arctic regions of the European North (Arkhangelsk Oblast, Murmansk Oblast, Komi Republic and Nenets Autonomous District. The Republic of Karelia has a special geographical position, and based on many socio-economic indicators is considered to be a «depressive» region. The expanded reproduction of human capital will bring the Republic of Karelia to the next level of development, taking into consideration external and internal factors as well as opportunities and threats. The results obtained in the study will expand the existing system of knowledge about reproduction of the human capital in the framework of spatial development, and the review of the expanded reproduction of human capital on the regional level will allow the government authorities to develop objective measures of quality formation of the region's human resources. It is proved that the introduction of the vocational guidance system in the region could lead to minimization of the threats associated with depopulation and the gap between education system and the

    Full Text Available Energy infrastructures in North-Central Nigeria are inadequate and grid electricity is unable to meet suburban housing electricity demand. The alternative power-supply options proposed by government for the region require appropriation analysis for selection. Four public housing estates in suburban Abuja are selected for electricity demand analysis under conventional and energy-efficient lighting scenarios; then techno-economic parameters of two off-grid electric power supply systems (PV and Diesel-powered generation to meet these electricity demands are evaluated. An energy techno-economic assessment methodology is used. The study determines the energy-efficient lighting system is appropriate with 40% energy savings relative to the Conventional Lighting Systems. The diesel generator alternative power-supply option has Life Cycle Costs almost 4 times those of the PV option. The study established the PV-energy-efficient lighting system as the most feasible off-grid electric power supply alternative for implementation.

    Highlights: • The thermodynamic and economic evaluation of power plant have been studied. • Saving and boosting modes are considered as the same solar field area. • Two modes of operation have been used and simulated on Libyan climate conditions. • The benefit/cost ratios are 1.74 and 1.30 for fuel saving and power boosting mode. • Fuel saving mode is more economical than power boosting mode. - Abstract: The aim of this paper is to study the thermodynamic performance of a proposed integrated solar/North Benghazi combined power plant under Libyan climatic conditions. The parabolic trough collector field with direct steam generation was considered as solar system. Two modes of operations with the same solar field area are considered: fuel saving mode in which the generated solar steam was used to preheat the combustion air in the gas turbine unit and power boosting mode in which the generated solar steam was added into the steam turbine for boosting the electrical power generated from steam turbine unit. Moreover, the economic impact of solar energy is assessed in the form of benefit/cost ratio to justify the substitution potential of such clean energy. This study shows that, for fuel saving mode: the annual saving of natural gas consumption and CO_2 emission are approximately 3001.56 and 7972.25 tons, respectively, in comparison with the conventional North Benghazi combined cycle power plant. For power boosting mode: the annual solar share of electrical energy is approximately 93.33 GW h. The economic analysis of solar supported plant has indicated that the benefit/cost ratios are 1.74 and 1.30 for fuel saving and power boosting mode, therefore, then fuel saving mode is more economical than power boosting mode for the same solar field area, moreover, it reduces the greenhouse CO_2 emission in order to avoid a collapse of the word climate.

  8. Biography of a technology: North America's power grid through the twentieth century

    Science.gov (United States)

    Cohn, Julie A.

    North Americans are among the world's most intense consumers of electricity. The vast majority in the United States and Canada access power from a network of transmission lines that stretch from the East Coast to the West Coast and from Canada to the Mexican Baja. This network, known as the largest interconnected machine in the world, evolved during the first two thirds of the twentieth century. With the very first link-ups occurring at the end of the 1890s, a wide variety of public and private utilities extended power lines to reach markets, access and manage energy resources, balance loads, realize economies of scale, provide backup power, and achieve economic stability. In 1967, utility managers and the Bureau of Reclamation connected the expansive eastern and western power pools to create the North American grid. Unlike other power grids around the world, built by single, centrally controlled entities, this large technological system emerged as the result of multiple decisions across eighty-five years of development, and negotiations for control at the economic, political, and technological levels. This dissertation describes the process of building the North American grid and the paradoxes the resulting system represents. While the grid functions as a single machine moving electricity across the continent, it is owned by many independent entities. Smooth operations suggest that the grid is a unified system; however, it operates under shared management and divided authority. In addition, although a single power network seems the logical outcome of electrification, in fact it was assembled through aggregation, not planning. Interconnections intentionally increase the robustness of individual sub-networks, yet the system itself is fragile, as demonstrated by major cascading power outages. Finally, the transmission network facilitates increased use of energy resources and consumption of power, but at certain points in the past, it also served as a technology of

    Seabed sediment mapping is important for a wide range of marine policy, planning and scientific issues, and there has been considerable national and international investment around the world in the collation and synthesis of sediment datasets. However, in Europe at least, much of this effort has been directed towards seabed classification and mapping of discrete habitats. Scientific users often have to resort to reverse engineering these classifications to recover continuous variables, such as mud content and median grain size, that are required for many ecological and biophysical studies. Here we present a new set of 0.125° by 0.125° resolution synthetic maps of continuous properties of the north-west European sedimentary environment, extending from the Bay of Biscay to the northern limits of the North Sea and the Faroe Islands. The maps are a blend of gridded survey data, statistically modelled values based on distributions of bed shear stress due to tidal currents and waves, and bathymetric properties. Recent work has shown that statistical models can predict sediment composition in British waters and the North Sea with high accuracy, and here we extend this to the entire shelf and to the mapping of other key seabed parameters. The maps include percentage compositions of mud, sand and gravel; porosity and permeability; median grain size of the whole sediment and of the sand and the gravel fractions; carbon and nitrogen content of sediments; percentage of seabed area covered by rock; mean and maximum depth-averaged tidal velocity and wave orbital velocity at the seabed; and mean monthly natural disturbance rates. A number of applications for these maps exist, including species distribution modelling and the more accurate representation of sea-floor biogeochemistry in ecosystem models.

    The November 25, 1988, Saguenay earthquake of magnitude M b L g = 6.5 occurred in the province of Quebec, Canada. It represents the first strong event in eastern North America for which the seismic behavior of a power system is documented. The paper describes the seismic performance of the main components of the power system with emphasis on damages to the substation's equipment and on the triggering of control and protection devices by the seismic waves. Performance of the network is analyzed taking in account the seismological and strong ground motion features. Attention is drawn to general observations related to soil conditions and topographical relief. These data, when extrapolated to the eastern North American context, indicate that caution must be exercised concerning the seismic resistance of lifelines in eastern Canada and United States

    In European and American nations, competitive principle was also recently introduced to electric industry allowed its local exclusion as a public business before today by liberalization of electric power market due to regulative relaxation, and then the existing electric power companies are now under serious competition with the other companies, of course with IPP which is its new comer. And, as nuclear power generation has already established there its position for an important source essential for electric power supply, by liberalization of electric power economy has also been severely required to the nuclear power generation. Then, the electric power companies intend to carry out cost-down by various means such as contraction of periodical inspection, and so on. Especially, in U.S.A., not only rationalization effort at a pace of every company but also various cost-down procedures ranging to reorganization of business such as purchase of other company power station, establishment of operation company integrally carrying out operation management of some companies, and so on, As a result, the nuclear power generation has come to obtain an evaluation to be an electric source sufficiently capable of competing with the other sources even at competitive market. On the other hand, its new construction continues at difficult condition. By adding to traditional objection against nuclear energy, in general, by recently entering of environmental protection party to the regime in some nations of western Europe, political environment around nuclear energy becomes unstable. And, liberalization of electric power also forms an investment environment advantageous for natural gas burning thermal power plants capable of carrying out short term capital recovery, in general. Therefore, the electric companies tend strongly to correspond to rather life elongation of the present plant than new plan construction. (G.K.)

    Full Text Available Phosphaenus hemipterus (Goeze is a Palaearctic glow worm (Coleoptera: Lampyridae, previously been reported in North America on the basis of two specimens; one collected in 1947 in Yarmouth, Nova Scotia; the other in 1989 in Montreal, Quebec. The present study newly records it from three sites in Halifax, Nova Scotia. One hundred and twenty six adult males and larvae were collected in 2009 in disturbed urban grassland areas, similar to habitats in England and Belgium where the species has been investigated. Experiments confirm that larvae feed on earthworms (Lumbricus terrestris, consistent with observations in Europe. The habitat is described, including vegetation, potential predators, and prey. Although ballast-shipments have previously been proposed as a vector for the species’ introduction to North America, the present study suggests that the importation of agricultural and horticultural products, which has lead to the introduction of many earthworms to the continent, could also serve as a conduit for the introduction of obligate earthworm predators such as the larvae of P. hemipterus. Although an adventive species, possible conservation concerns are discussed for a species that is considered endangered in parts of its native range.

    The process of liberalising European electricity markets, encompassing a wide range of restructuring activities, has mainly been spurred by the attempt to increase the economic efficiency of the whole sector. This process might be used to trigger a development towards a sustainable power sector by increasing the use of renewable energy sources and enhancing energy efficiency on the supply and demand side. However, by taking a closer look at the current trends of the European electricity markets, it becomes obvious that the liberalisation not only implies opportunities but also risks for the creation of a sustainable power sector. Many of these risks are due to market distortions and imperfections caused by the delay in creating a fully functional single European market. Thus, in the short-term, the market liberalisation tends to constitute more risks than opportunities without government actions to prevent these risks. In the long run, though, the efficiency gains of the sector and the appearance of new market factors are likely to bring forth the opportunities of liberalisation and actively foster a transformation towards a sustainable electricity sector.

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

    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.

    This paper uses a static computational game theoretic model of a fully opened European electricity market and can take strategic interaction among electricity-producing firms into account. The model is run for a number of scenarios: first, in the baseline under perfect competition, the prices differ due to the presence of various generation technologies and a limited ability to exchange electricity among countries. In addition, when large firms exercise market power, the model runs indicate that prices are the highest in countries where the number of firms is low. Second, dry weather would increase the prices in the hydro-rich Nordic countries followed by the Alpine countries. The price response would be about 20% higher with market power. Third, more transmission capacity would lower the prices in countries with high prices and it also reduces the impact of market power. Hence, more transmission capacity can improve market competitiveness. (author)

    accurate information on the overall indices and new regional development trends. Public's perceptions is evolving into the right direction with respect to nuclear power. As a result of public debates, more and more people become aware, understand and place proper confidence in nuclear technology that is environmentally friendly while offering safe, reliable and cost effective industrial electricity. Once concluded the Agreement of Accession to the European Union on February 1st, 1995, Romania irreversibly committed itself onto the way of the European integration, assuming increased responsibilities regarding the compliance with the Copenhagen criteria. The conclusion of the analysis carried out by the European Commission '2000 Agenda', confirmed by the Western Europe Nuclear Regulators' Association - WENRA, were in favor of Romania and Slovenia, presently the only countries in the Central and South-eastern Europe that hold nuclear units (Cernavoda and Krsko, respectively) based on western technology design. It is obviously that each country is monitored and evaluated for the purpose of harmonizing all the units' nuclear safety standards imposed on European level. The following conclusions come out of the aforesaid: - The electric power developed in Romania based on the CANDU Western Technology successfully complies with the nuclear safety requirements and standards. Thus, considering this pre-requisite, the process of our country's accession to the European structure is not jeopardized; - moreover by using the own resources of natural uranium and heavy water for the industrial generation of electricity, Romania is contributing to its own safe supply and EU's safe supply as well, after the accession; - the development strategies and policies in the electric power in Romania are harmonized with the present ones provided for the EU development, what is confirmed by the current support granted by EURATOM for the completion of the Cernavoda NPP Unit 2.

    This contribution analyses the European electricity markets with respect to their aptitude to absorb large amounts of wind energy. Thereby in a first step the market designs of the major European power markets in France, Germany, Scandinavia, Spain and UK are reviewed, with a particular focus on liquidity in the spot and intraday markets. Then some key features of the short-term adjustments required by wind energy are discussed and the necessity of sufficient liquidity in intraday markets is highlighted. For the example of the German market subsequently the discrepancy between the physical short-term adjustment needs and the traded volumes on the intraday market is analyzed. This leads to an evaluation of proposals for improving the liquidity on the short-term market, including the use of continuous spot trading like in UK or the use of intraday auctions like in Spain.

  1. Promoting investments in combined heat and power production in East-European countries

    1992-01-01

    The study concerns the evaluation of the potential of Combined Heat and Power (CHP) locations, both in industry and district heating with a heat demand of at least 20 GJ/h or ca. 1 MWe capacity. In fact 58 Hungarian locations were analyzed on scope and profitability for investment in CHP, using financial accounting models and criteria such as Internal Rate of Return and Pay-back Period. Due to the already existing favourable infrastructure in East European countries the present expectations in Hungary about the CHP capacity to be developed in the future are very optimistic (1300 up till 2000 MWe in the year 2000). Clearly there exist an overoptimism concerning the possibilities of increasing the energy efficiency in former East-European countries by investment in cogeneration. A more financially and economic attractive way for efficiency improvements is promoting energy saving in these countries and thus avoiding investments in supply technologies. 6 refs

  2. The North American power delivery system: Balancing market restructuring and environmental economics with infrastructure security

    2006-01-01

    The North American electric power system was developed over the last 100 years without a conscious awareness and analysis of the system-wide implications of its current evolution under the forces of deregulation, system complexity, power-market impacts, terrorism, and human error. The possibility of power delivery beyond neighboring areas was a distant secondary consideration. Today, the North American power network may realistically be considered to be the largest machine in the world. With the advent of deregulation and competition in the electric power industry, new ways are being sought to improve the efficiency of that network without seriously diminishing its reliability and security. Controlling a heterogeneous, widely dispersed, yet globally interconnected system is a serious technological problem in any case. It is even more complex and difficult to control it for optimal efficiency and maximum benefit to the ultimate consumers while still allowing all its business components to compete fairly and freely. In this paper we present an overview of key issues and the context in which the electricity infrastructure is being operated under the above forces along with a strategic vision extending to a decade, or longer, that would enable more secure and robust systems operation, security monitoring, and efficient energy markets.

With respect to the intended global character of the USEtoxTM model, different approaches to determine normalization references of other economic systems (e.g. Asia or world) are discussed in relation to these findings. Overall, we thus...... recommend the use of the provided set of normalization references for USEtoxTM, but we also advocate 1) to perform an update as soon as a more comprehensive inventory can be obtained and as soon as characterization factors for metals are revised; 2) to consider extension to other economic systems in order...

  4. Nonlinear Response of the Stratosphere and the North Atlantic-European Climate to Global Warming

    The response of the northern winter atmospheric circulation for two consecutive global warming periods of 2 K is examined in a grand ensemble (68 members) of idealized CO2 increase experiments performed with the same climate model. The comparison of the atmospheric responses for the two periods shows remarkable differences, indicating the nonlinearity of the response. The nonlinear signature of the atmospheric and surface responses is reminiscent of the positive phase of the annular mode of variability. The stratospheric vortex response shifts from an easterly wind change for the first 2 K to a westerly wind change for the second 2 K. The North Atlantic storm track shifts poleward only in the second period. A weaker November Arctic amplification during the second period suggests that differences in Arctic sea ice changes can act to trigger the atmospheric nonlinear response. Stratosphere-troposphere coupling thereafter can provide for the persistence of this nonlinearity throughout the winter.

  5. The effect of fish impingement at Sizewell 'A' Power Station, Suffolk, on North Sea fish stocks

    Samples collected from the cooling water intake screens of Sizewell 'A' power station over a 12 month period contained 73 species of fish. Of these, only 20 species were present on more than 50% of sampling dates and only 7 commercially exploited species were caught in quantities of more than a few hundred over the year; namely sprat, herring, cod, whiting, sole, dab and plaice. These species formed the basis of analysis of the impact of the Power Station on commercial species. Commercial species found in the Sizewell area are part of major North Sea stocks. The impact of the losses due to the Power Station is spread over these stocks, hence the effect is minimal. The mortality rate caused by the Power Station is one thousandth to one hundred-thousandth, depending on species, of that caused by commercial fishing and the effect is less than that of a small, inefficient commercial trawler.

  6. North-south polarization of European electricity consumption under future warming.

    There is growing empirical evidence that anthropogenic climate change will substantially affect the electric sector. Impacts will stem both from the supply side-through the mitigation of greenhouse gases-and from the demand side-through adaptive responses to a changing environment. Here we provide evidence of a polarization of both peak load and overall electricity consumption under future warming for the world's third-largest electricity market-the 35 countries of Europe. We statistically estimate country-level dose-response functions between daily peak/total electricity load and ambient temperature for the period 2006-2012. After removing the impact of nontemperature confounders and normalizing the residual load data for each country, we estimate a common dose-response function, which we use to compute national electricity loads for temperatures that lie outside each country's currently observed temperature range. To this end, we impose end-of-century climate on today's European economies following three different greenhouse-gas concentration trajectories, ranging from ambitious climate-change mitigation-in line with the Paris agreement-to unabated climate change. We find significant increases in average daily peak load and overall electricity consumption in southern and western Europe (∼3 to ∼7% for Portugal and Spain) and significant decreases in northern Europe (∼-6 to ∼-2% for Sweden and Norway). While the projected effect on European total consumption is nearly zero, the significant polarization and seasonal shifts in peak demand and consumption have important ramifications for the location of costly peak-generating capacity, transmission infrastructure, and the design of energy-efficiency policy and storage capacity.

  7. Genetic structure of Europeans: a view from the North-East.

    Directory of Open Access Journals (Sweden)

    Mari Nelis

    Full Text Available Using principal component (PC analysis, we studied the genetic constitution of 3,112 individuals from Europe as portrayed by more than 270,000 single nucleotide polymorphisms (SNPs genotyped with the Illumina Infinium platform. In cohorts where the sample size was >100, one hundred randomly chosen samples were used for analysis to minimize the sample size effect, resulting in a total of 1,564 samples. This analysis revealed that the genetic structure of the European population correlates closely with geography. The first two PCs highlight the genetic diversity corresponding to the northwest to southeast gradient and position the populations according to their approximate geographic origin. The resulting genetic map forms a triangular structure with a Finland, b the Baltic region, Poland and Western Russia, and c Italy as its vertexes, and with d Central- and Western Europe in its centre. Inter- and intra- population genetic differences were quantified by the inflation factor lambda (lambda (ranging from 1.00 to 4.21, fixation index (F(st (ranging from 0.000 to 0.023, and by the number of markers exhibiting significant allele frequency differences in pair-wise population comparisons. The estimated lambda was used to assess the real diminishing impact to association statistics when two distinct populations are merged directly in an analysis. When the PC analysis was confined to the 1,019 Estonian individuals (0.1% of the Estonian population, a fine structure emerged that correlated with the geography of individual counties. With at least two cohorts available from several countries, genetic substructures were investigated in Czech, Finnish, German, Estonian and Italian populations. Together with previously published data, our results allow the creation of a comprehensive European genetic map that will greatly facilitate inter-population genetic studies including genome wide association studies (GWAS.

  8. The state of the North-European electricity market. Attempt to a problem-oriented analysis

    This analysis covers the period 2000-2005, plus a few longer prognoses. Most analyses that preceded the deregulation of the electricity market in Europe, held the opinion that the market, due to the important over capacity, would be characterized by a severe price competition and lead to a market restructuration with only a few large producers surviving. The need for new investments was considered to be limited. Even a growing demand for electricity would not disturb the price reductions. The development followed this scheme to a certain extent. The restructuring is taking place. The utilities EdF (France), ENI (Italy), E.On, RWE (both Germany) and Vattenfall (Sweden) are obtaining dominant positions on their largely extended markets. But the prices have been stabilized on a level above the marginal production costs, and the power surplus has been halved compared to 1998. Northern Europe is approaching a state with increasing prices and threatening power shortages. The producers have adapted to the new situation by exploiting the differences in production- and demand-structure in the different countries and the associated price differences. Producers in Germany have instead of competing with the price chosen to close down a number of plants with large investment needs and high operating costs. The energy policy of all countries in the region gives highest priority to investment in renewable energy sources, which can not replace all the capacity lost by closing fossil and nuclear power plants. The ambition of the power producers to regain control of the market and the political inclination to prioritize CO 2 -free power production has, in combination, led to a strengthening of the existing producers and denying market access for new larger actors. New base load production capacity will be needed in the long run, and investment decisions are needed in the near future, if risks for power shortages are to be avoided. Increasing prices will stimulate commercial

    1. Energy policy post-Fukushima: • Following the initial shock: differentiated development, no cohesive European policy; • EU: Nuclear Power (NP) remains important in the context of climate policy; • Bulk of European countries: Keep or even expand share of NP (UK, Eastern Europe); • Germany and Switzerland (CH): Exit from NP, in Germany based on previously fixed shutdown deadlines for every facility, in CH based on exclusion of new builds. 2. Switzerland's focus: • Current CH electricity supply: twin pillars of NP + hydro power; high sustainability. • Federal Council's new energy strategy and its consequences: Strain on economy and companies due to market distortion and high renovation costs; plus growing environmental stress, dependency on imports and social inequality due to artificially high electricity prices. 3. Future of nuclear power in Switzerland: Conceivable possibilities: • Short-term: Relatively rapid ban on nuclear power (but poss. with back-door research/no ban on thinking about the technology); • Medium-term: Ban on new facilities but old plants continue to operate; • Long-term: Re-entry/new start, poss. even sanctioned by politicians, on the following grounds: rather new facilities than old, good for the climate, costeffectiveness, energy security. 4. A new look for nuclear power? HTR technology of particular interest due to the following benefits: • Disposal (less waste, recycling); • Technical controllability, core meltdown impossible; • Manageable dimensions (particularly important in CH); • Financial feasibility. Whether NP will remain on the agenda, and which technology wins through also depends heavily on external factors: climate policy, cost-effectiveness/financial feasibility, readiness for market, change in value, trends in other energy sources. 5. Summary: Future of NP difficult to predict. If technology is mature and launched on the market within a reasonable time frame, the potential is there. Opportunities

    2007-01-01

    This paper presents a newly established database of the European power plant infrastructure (power plants, fuel infrastructure, fuel resources and CO 2 storage options) for the EU25 member states (MS) and applies the database in a general discussion of the European power plant and natural gas infrastructure as well as in a simple simulation analysis of British and German power generation up to the year 2050 with respect to phase-out of existing generation capacity, fuel mix and fuel dependency. The results are discussed with respect to age structure of the current production plants, CO 2 emissions, natural gas dependency and CO 2 capture and storage (CCS) under stringent CO 2 emission constraints. The analysis of the information from the power plant database, which includes planned projects, shows large variations in power plant infrastructure between the MS and a clear shift to natural gas-fuelled power plants during the last decade. The data indicates that this shift may continue in the short-term up to 2010 since the majority of planned plants are natural gas fired. The gas plants are, however, geographically concentrated to southern and northwest Europe. The data also shows large activities in the upstream gas sector to accommodate the ongoing shift to gas with pipelines, liquefaction plants and regasification terminals being built and gas fields being prepared for production. At the same time, utilities are integrating upwards in the fuel chain in order to secure supply while oil and gas companies are moving downwards the fuel chain to secure access to markets. However, it is not yet possible to state whether the ongoing shift to natural gas will continue in the medium term, i.e. after 2010, since this will depend on a number of factors as specified below. Recently there have also been announcements for construction of a number of new coal plants. The results of the simulations for the German and British power sector show that combination of a relatively low

    The North Atlantic Oscillation (NAO) is responsible for the climatic variability in the Northern Hemisphere, in particular, in Europe and is related to extreme events, such as droughts. The purpose of this paper is to study the correlation between precipitation and winter (December-January-February-March (DJFM)) NAO both for the historical period (1951-2000) and two future periods (2001-2050 and 2051-2100). NAO is calculated for these three periods by using sea level pressure, while precipitation data from seven climate models following the representative concentration pathway (RCP) 8.5 are also used in this study. An increasing trend in years with positive DJFM NAO values in the future is defined by this data, along with higher average DJFM NAO values. The correlation between precipitation and DJFM NAO is high, especially in the Northern (high positive) and Southern Europe (high negative). Therefore, higher precipitation in Northern Europe and lower precipitation in Southern Europe are expected in the future. Cross-spectral analysis between precipitation and DJFM NAO time series in three different locations in Europe revealed the best coherence in a dominant cycle between 3 and 4 years. Finally, the maximum drought period in terms of consecutive months with drought is examined in these three locations. The results can be used for strategic planning in a sustainable water resources management plan, since there is a link between drought events and NAO.

    Atmospheric deposition from industry in Russian tundra and taiga. - Trace metal composition of winter snowpack, snow-melt filter residues and top-soil samples were determined along three transects through industrial towns in the Usa basin, North-East Russia: Inta, Usinsk and Vorkuta. Snow was analysed for Ag, Al, As, Ba, Cd, Co, Cr, Cu, Mn, Ni, Pb, Sr and Zn using ICP-MS (Ca and K by F-AAS for Vorkuta only), pH and acidity/alkalinity. Filter residues were analysed for: Al, Ba, Ca, Cd, Cu, K, Mg, Mn, Ni, Pb, Sr and Zn using F-AAS and GF-AAS; top-soil samples were analysed for Ba, Cu, Mg, Mn, Na, Ni, Pb, Sr, Zn using F-AAS. Results indicate elevated concentrations of elements associated with alkaline combustion ash around the coal mining towns of Vorkuta and Inta. There is little evidence of deposition around the gas and oil town of Usinsk. Atmospheric deposition in the vicinity of Vorkuta, and to a lesser extent Inta, added significantly to the soil contaminant loading as a result of ash fallout. Acid deposition was associated with pristine areas whereas alkaline combustion ash near to emission sources more than compensated for the acidity caused by SO 2

    Genetic and morphological similarity between populations separated by large distances may be caused by frequent long-distance dispersal or retained ancestral polymorphism. The frequent lack of differentiation between disjunct conspecific moss populations on different continents has traditionally been explained by the latter model, and has been cited as evidence that many or most moss species are extremely ancient and slowly diverging. We have studied intercontinental differentiation in the amphi-Atlantic peat moss Sphagnum angermanicum using 23 microsatellite markers. Two major genetic clusters are found, both of which occur throughout the distributional range. Patterns of genetic structuring and overall migration patterns suggest that the species probably originated in North America, and seems to have been established twice in Northern Europe during the past 40,000 years. We conclude that similarity between S. angermanicum populations on different continents is not the result of ancient vicariance and subsequent stasis. Rather, the observed pattern can be explained by multiple long-distance dispersal over limited evolutionary time. The genetic similarity can also partly be explained by incomplete lineage sorting, but this appears to be caused by the short time since separation. Our study adds to a growing body of evidence suggesting that Sphagnum, constituting a significant part of northern hemisphere biodiversity, may be more evolutionary dynamic than previously assumed. © 2010 The Author(s).

    Atmospheric transport of midlatitude pollutant emissions to the Arctic can result in disproportionate impacts on the receptor region. We use carbon monoxide (CO), a tracer of incomplete combustion, to study changes in pollutant transport to the Arctic. Using a wavelet transform, we spectrally decompose CO mole fraction measurements from three Arctic sites (Alert, Barrow, and Zeppelin) collected by NOAA over the past 20-25 years. We show that CO concentrations have decreased by -1.0 to -1.2 ppb/yr. We find that the dampened seasonal cycle (-1.2 to -2.3 ppb/yr) is mostly due to a reduction in peak concentrations (-1.5 to -2.4 ppb/yr), which we attribute to reduced source emissions. We find no evidence to support a persistent increase in hydroxyl radical concentration. Using the GEOS-Chem global 3-D chemistry transport model, we show that observed decreases are consistent with reductions in fossil fuel usage from Europe and North America.

    Canine distemper virus (CDV) creates a very contagious viral multi-systemic canine distemper (CD) disease that affects most species of Carnivora order. The virus is genetically heterogeneous, particularly in section of the hemagglutinin (H) gene. Sequence analysis of the H gene can be useful to investigate distinction of various lineages related to geographical distribution and CDV molecular epidemiology. Since vaccination program is conducted only in large cities of Iran, CD still remains as one of the major causes of death in dogs in this country. In order to monitor H gene, CDV has been detected in 14 out of 19 sampled dogs through the amplification of nucleoprotein (NP) gene in nested-PCR assay. In the next step 665 bp of H gene was amplified in 9 out of 14 NP-gene positive dogs. Phylogenetic analysis distinguished two distinct CDV genotypes in Iran. JN941238 has been embedded in European cluster and JN941239 has been embedded in Arctic cluster. Nucleic analysis has been shown high difference among both Iranian CDV lineages with CDV vaccine strains.

    East Asia and North America are the regions most heavily affected by powerful cyclones. In this paper we investigate the morphological characteristics of ionospheric disturbances induced by cyclones in different continents. The global ionosphere map supplied by the Center for Orbit Determination in Europe (CODE), International Reference Ionosphere Model (IRI) 2012, and Wallops Island ionosonde station data are used to analyse the ionospheric variations during powerful typhoons/hurricanes in East Asia and North America, respectively. After eliminating the ionospheric anomalies due to the solar-terrestrial environment, the total electron content (TEC) time series over the point with maximum wind speed is detected by the sliding interquartile range method. The results indicate that significant ionospheric disturbances are observed during powerful tropical cyclones in East Asia and North America, respectively, and that all the ionospheric anomalies are positive. In addition, the extent and magnitude of travelling ionospheric disturbances are associated with the category of tropical cyclone, and the extent of TEC anomalies in longitude is more pronounced than that in latitude. Furthermore, the maximum ionospheric anomaly does not coincide with the eye of the storm, but appears in the region adjacent to the centre. This implies that ionospheric disturbances at the edges of cyclones are larger than those in the eye of the winds. The phenomenon may be associated with the gravity waves which are generated by strong convective cells that occur in the spiral arms of tropical cyclones. This comprehensive analysis suggests that the presence of powerful typhoons/hurricanes may be a possible source mechanism for ionospheric anomalies.

    This article draws attention to problems important for all EU power consumers-the unfairness in individual payments for power transmission and in the cross-border subsidy element in the mechanism of Inter-Transmission System Operators (TSO) Compensation (ITC). A brief review of power transmission tariffs brings out the structure of the problems. A short retrospection explains their growth. The essence of the ITC mechanism is explained and existing shortcomings are illustrated. The deficiencies of existing regulations for transmission pricing are analyzed. In the light of this analysis, the ITC problem is reconsidered and defined more precisely. The basic prerequisites to an ITC reformulation process are presented. The main principles of a new simple, transparent and equitable approach are suggested, in accordance with the contemporary legal positions and functions of the TSOs. - Highlights: → Investigations in the mechanism known as Inter-TSO Compensation (ITC). → Deficiencies in European regulations for cross-border power transmission payments. → Main principles of a new approach avoiding the existing cross-subsidies. → Appeal for reconsideration and a more precise definition of the ITC problem. → Public welfare enhancement by fairness in payment for power transmission.

  20. Tropospheric mid-latitude geopotential wave characteristics associated with strong wind events in the North Atlantic/European region

    The variability of strong synoptic scale wind events in the mid-latitudes have long been linked to baroclinic wave activity in the mid troposphere. Previous studies have also shown that greater amplitudes of planetary waves in the mid troposphere are likely to increase the occurrence of regional extremes in temperature and precipitation. In this study we examine whether characteristics of planetary and synoptic mid-latitude waves show systematic anomalies in the North Atlantic/ European region which can be related to the occurrence of a strong surface wind event. We will mainly focus on two questions: 1) Do amplitudes for waves with different wave lengths show a systematic anomaly when a strong wind event occurs? 2) Can phases of the individual wave components be detected that favour strong wind events? In order to decompose the mid-tropospheric flow into longitudinal waves we employ the fast Fourier transform to the meridional mean of the geopotential height in 500hPa between 35° and 60°N for i) the entire latitude belt and ii) for a North Atlantic/European sector (36°W to 36°E). Our definition of strong wind events is based on the Storm Severity Index (SSI) alongside a wind tracking algorithm identifying areas of exceedances of the local 98th percentile of the 10m wind speed. First results using ERA-Interim Reanalysis from 1979 - 2014 for the extended winter season (ONDJFM) for the 50 most intense strong wind systems with respect to the SSI reveal a greater amplitude for all investigated wave numbers. Especially waves with wave lengths below 2000km show an increase of about 25% of the daily standard deviation on average. The distribution of wave phases for the different wave numbers with respect to the location of a strong wind event shows a less homogenous picture. There is however a high proportion of events that can be associated with phases around 3π/4 and 5π/4 of waves with lengths of around 6000km, equivalent to wave number 5 on a planetary scale

    Several radiotracers that bind to fibrillar amyloid-beta in the brain have been developed and used in various patient cohorts. This study aimed to investigate the comparability of two amyloid positron emission tomography (PET) tracers as well as examine how age affects the discriminative properties of amyloid PET imaging. Fifty-one healthy controls (HCs), 72 patients with mild cognitive impairment (MCI) and 90 patients with Alzheimer's disease (AD) from a European cohort were scanned with [11C]Pittsburgh compound-B (PIB) and compared with an age-, sex- and disease severity-matched population of 51 HC, 72 MCI and 84 AD patients from a North American cohort who were scanned with [18F]Florbetapir. An additional North American population of 246 HC, 342 MCI and 138 AD patients with a Florbetapir scan was split by age (55-75 vs 76-93 y) into groups matched for gender and disease severity. PET template-based analyses were used to quantify regional tracer uptake. The mean regional uptake patterns were similar and strong correlations were found between the two tracers across the regions of interest in HC (ρ = 0.671, p = 0.02), amyloid-positive MCI (ρ = 0.902, p < 0.001) and AD patients (ρ = 0.853, p < 0.001). The application of the Florbetapir cut-off point resulted in a higher proportion of amyloid-positive HC and a lower proportion of amyloid-positive AD patients in the older group (28 and 30 %, respectively) than in the younger group (19 and 20 %, respectively). These results illustrate the comparability of Florbetapir and PIB in unrelated but matched patient populations. The role of amyloid PET imaging becomes increasingly important with increasing age in the diagnostic assessment of clinically impaired patients. (orig.)

    An analysis of the frequency of cyclones and surface wind velocity for the Euro-Atlantic sector is performed by means of an objective methodology. Monthly and seasonal trends of cyclones and wind speed magnitude are computed and trends between 1960 and 2000 evaluated. Results reveal a significant frequency decrease (increase) in the western Mediterranean (Greenland and Scandinavia), particularly in December, February, and March. Seasonal and monthly analysis of wind magnitude trends shows similar spatial patterns. We show that these changes in the frequency of low-pressure centers and the associated wind patterns are partially responsible for trends in the significant height of waves. Throughout the extended winter months (October-March), regions with positive (negative) wind magnitude trends, of up to 5 cm/s/year, often correspond to regions of positive (negative) significant wave height trends. The cyclone and wind speed trends computed for January-March are well matched by the corresponding trends in significant wave height, with February being the month with the highest trends (negative south of lat 50 degrees N up to -3 cm/year, and positive up to 5 cm/year just north of Scotland). Trends in European precipitation are assessed using the Climatic Research Unit data set. The results of the assessment emphasize the link with the corresponding tendencies of cyclone frequencies. Finally, it is shown that these changes are associated, to a large extent, with the preferred phases of major large-scale atmospheric circulation modes, particularly with the North Atlantic Oscillation, the eastern Atlantic pattern, and the Scandinavian pattern.

    Interest in climate change effects on groundwater has increased dramatically during the last decade. The mechanisms of climate-related groundwater depletion have been thoroughly reviewed, but the influence of global warming on groundwater-dependent ecosystems (GDEs) remains poorly known. Here we report long-term water temperature trends in 66 northern European cold-water springs. A vast majority of the springs (82%) exhibited a significant increase in water temperature during 1968-2012. Mean spring water temperatures were closely related to regional air temperature and global radiative forcing of the corresponding year. Based on three alternative climate scenarios representing low (RCP2.6), intermediate (RCP6) and high-emission scenarios (RCP8.5), we estimate that increase in mean spring water temperature in the region is likely to range from 0.67 °C (RCP2.6) to 5.94 °C (RCP8.5) by 2086. According to the worst-case scenario, water temperature of these originally cold-water ecosystems (regional mean in the late 1970s: 4.7 °C) may exceed 12 °C by the end of this century. We used bryophyte and macroinvertebrate species data from Finnish springs and spring-fed streams to assess ecological impacts of the predicted warming. An increase in spring water temperature by several degrees will likely have substantial biodiversity impacts, causing regional extinction of native, cold-stenothermal spring specialists, whereas species diversity of headwater generalists is likely to increase. Even a slight (by 1 °C) increase in water temperature may eliminate endemic spring species, thus altering bryophyte and macroinvertebrate assemblages of spring-fed streams. Climate change-induced warming of northern regions may thus alter species composition of the spring biota and cause regional homogenization of biodiversity in headwater ecosystems. © 2015 John Wiley & Sons Ltd.

    Corn (Zea mays L.) cobs are being evaluated as a potential bioenergy feedstock for combined heat and power generation (CHP) and conversion into a biofuel. The objective of this study was to determine corn cob availability in north central United States (Minnesota, North Dakota, and South Dakota) using existing corn grain ethanol plants as a proxy for possible future co-located cellulosic ethanol plants. Cob production estimates averaged 6.04 Tg and 8.87 Tg using a 40 km radius area and 80 km radius area, respectively, from existing corn grain ethanol plants. The use of CHP from cobs reduces overall GHG emissions by 60%–65% from existing dry mill ethanol plants. An integrated biorefinery further reduces corn grain ethanol GHG emissions with estimated ranges from 13.9 g CO 2  equiv MJ −1 to 17.4 g CO 2  equiv MJ −1 . Significant radius area overlap (53% overlap for 40 km radius and 86% overlap for 80 km radius) exists for cob availability between current corn grain ethanol plants in this region suggesting possible cob supply constraints for a mature biofuel industry. A multi-feedstock approach will likely be required to meet multiple end user renewable energy requirements for the north central United States. Economic and feedstock logistics models need to account for possible supply constraints under a mature biofuel industry. - Highlights: • Corn cob biomass was estimated for the north central United States region. • Cobs were evaluated for combined heat and power generation and bioethanol. • Co-located ethanol plants showed a reduction in greenhouse gas emissions. • Biomass supply constraints may occur under a mature cellulosic ethanol scenario

  7. Trading in the rain. Rainfall and European power sector emissions. Research note no. 9

    International Nuclear Information System (INIS)

    2006-01-01

    Analysts often say that temperature and rainfall have an impact on the price of CO 2 , as they influence the conditions of electric power supply and demand. Rainfall mainly affects the capacity of hydropower production, the third largest source of electricity in Europe and by far the leading source of renewable energy. The variability of hydroelectric volumes is indeed usually offset by other, higher-emitting sources of electricity, which has repercussions on the European allowances trading market. In 2005, rainfall was unusually low in several European countries: in the Iberian peninsula and in France, drought is believed to have brought about a rise of approximately 15 Mt CO 2 in power sector emissions. In contrast, hydrological conditions were particularly good in the Nordic countries, allowing them to reduce CO 2 emissions in the region as a whole through hydropower-based exports. The additional allowances demand would therefore have been 'only' about 9 Mt CO 2 . To make the interaction with the CO 2 market easier to understand, an indicator of rainfall in Europe must include this compensating phenomenon resulting from the heterogeneity of the climatic conditions and volumes produced in Europe

    Full Text Available Within the European Union, we can talk about a high degree of power and this means that states have different capacities to reach prosperity, but they also have the capacity to help other states reach a similar degree of welfare. Development Assistance plays a very important role in the world, being offered to states which can not surpass economic, social or political difficulties. In order to reach a certain balance at the international level, between levels of development that states possess, a fundamental need occurs: states that are economically, socially and politically left behind must receive development assistance. The present work aims to analyse the degree to which the European Union contributes to international development. Both EU institutions and EU and OECD member states play fundamental roles on the world stage by granting funds to fragile and less developed states.Rethinking the third world might mean a restructuring of the political systems of states and of their economic systems, so that these countries become more developed and less dependent on other states. European institutions and assistance policies also need to change their way of regarding the matter of international development and of approaching the problem of poverty so that the needs of the third world states could be satisfied in an appropriate manner. Europe has the role of transformative power because it helps the third world states develop their economies and political systems so that they could satisfy the needs of their citizens. As a consequence, these economies are transforming. They are not autarchic systems, so when we are talking about transformation, we are talking about development.

  9. Assimilation of ocean colour to improve the simulation and understanding of the North West European shelf-sea ecosystem

    Shelf-seas and coastal zones provide essential goods and services to humankind, such as fisheries, aquaculture, tourism and climate regulation. The understanding and management of these regions can be enhanced by merging ocean-colour observations and marine ecosystem simulations through data assimilation, which provides (sub)optimal estimates of key biogeochemical variables. Here we present a range of applications of ocean-colour data assimilation in the North West European shelf-sea. A reanalysis application illustrates that assimilation of error-characterized chlorophyll concentrations could provide a map of the shelf sea vulnerability to oxygen deficiency, as well as estimates of the shelf sea uptake of atmospheric carbon dioxide (CO2) in the last decade. The interannual variability of CO2 uptake and its uncertainty were related significantly to interannual fluctuations of the simulated primary production. However, the reanalysis also indicates that assimilation of total chlorophyll did not improve significantly the simulation of some other variables, e.g. nutrients. We show that the assimilation of alternative products derived from ocean colour (i.e. spectral diffuse attenuation coefficient and phytoplankton size classes) can overcome this limitation. In fact, these products can constrain a larger number of model variables, which define either the underwater light field or the structure of the lower trophic levels. Therefore, the assimilation of such ocean-colour products into marine ecosystem models is an advantageous novel approach to improve the understanding and simulation of shelf-sea environments.

    Phenotypic variation was characterized in 187 modern and archaeological specimens of the lesser white-toothed shrew (Crocidura suaveolens), obtained from both insular and continental European locations. Geometric morphometric methods were used to quantify variation in size and shape of the mandible. The phenotypic distance between populations, and the influence of several eco-geographical factors on the size and shape of the mandible in island populations, were assessed. Based on mandible shape divergence, the populations of C. suaveolens were clustered into continental, insular Atlantic and insular Mediterranean groups. Archaeological specimens from Molène Island, more than 3400 years old, display a mandible shape signal closer to that of the continental population than those of modern island populations. Conversely, the continental shape signals of the modern populations from Höedic and Sark suggest that these are relatively recent anthropogenic introductions. The populations of C. suaveolens from both the Atlantic and Mediterranean islands (except for Rouzic and Cyprus) show a significant increase in mandible size, compared to those from continental Europe. Significant phenotypic differences support the indigenous condition of C. suaveolens on most of the Atlantic islands, suggesting that the species arrived there before the separation of the Scilly Isles and Ushant from the continent due to the post-glacial rise in sea level. This provides an ante quem for its colonization of the north-western fringe of continental Europe, notwithstanding its absence from the region in the present day.

    Full Text Available European corn borer (Ostrinia nubilalis Hubner is one of the major corn pest in the world and in Croatia. Former investigations of corn borer in Croatia covered mostly its Eastern region. In trials conducted in 1998 and 1999 the research was extended to the North Western part of Croatia too. Macro trials were carried out with corn hybrids of FAO groups 200-600 at three localities: Križevci, Agricultural institute Osijek and at «Belje» PIK Karanac. In 1998 the intensity of the corn borer attack at the locality of «Belje» PIK Karanac was about 37.92% and in Agricultural institute Osijek 80.83%. In 1999 it varied between 37.08% at the locality of Agricultural Institute Osijek and 71.20% at the locality in Križevci. The estimated number of holes per plant in all three localities in both years was higher than the number of caterpillars. Length of damage per plant was between 0.38 and 18.80 cm. The data showed significant differences in the intensity of damaging effects on different localities while no significant differences concerning various hybrids were found. The statistical data concerning yield in both years showed significant differences among hybrids, localities and their interactions.

    Winter, W.

    2010-03-15

    Large capacities of wind generators have already been installed and are operating in Germany (26GW) and Spain (16GW). Installations which are as significant in terms of proportion to system size are also established in Denmark (3.3GW), the All Island Power System of Ireland and Northern Ireland (1.5GW), and Portugal (3.4GW). Many other countries expect significant growth in wind generation such that the total currently installed capacity in Europe of 68GW is expected to at least double by 2015. Yet further increases can be expected in order to achieve Europe's 2020 targets for renewable energy. The scale of this development poses big challenges for wind generation developers in terms of obtaining suitable sites, delivering large construction projects, and financing the associated investments from their operations. Such developments also impact the networks and it was to address the immediate transmission related challenges that the European Wind Integration Study (EWIS) was initiated by Transmission System Operators (TSOs) with the objective of ensuring the most effective integration of large scale wind generation into Europe's transmission networks and electricity system. The challenges anticipated and addressed include: 1) How to efficiently accommodate wind generation when markets and transmission access arrangements have evolved for the needs of traditional controllable generation. 2) How to ensure supplies remain secure as wind varies (establishing the required backup/reserves for low wind days and wind forecast errors as well as managing network congestion in windy conditions). 3) How to maintain the quality and reliability of supplies given the new generation characteristics. 4) How to achieve efficient network costs by suitable design and operation of network connections, the deeper infrastructure including offshore connections, and crossborder interconnections. EWIS has focused on the immediate network related challenges by analysing detailed

  14. The liberalization of the European energy market from the perspective of the Austrian regional power company

    Sander, H.

    1999-01-01

    This dissertation addresses the liberalization of the European energy sector from an Austrian perspective, emphasizing its effect on a regional power company (KELAG). The energy market's changing conditions are creating new opportunities for consumers that allow them to optimize their ability to fulfill their power requirements. Decentralized solutions are now just as viable for large industrial customers as the ability to have all energy supplied through the utility network. In addition, partnerships with independent power producers (IPP's) or cooperation between the large customers in energy production can be considered. From a regional perspective, the central management concept of KELAG is the answer to an altered market situation, since this concept created tremendous potential for streamlining the management of energy production and operation of the network. The liberalization of the energy market for large industrial customers in Carinthia's electricity sector was preceded by a series of important decisions. The Verbundgesellschaft combine their generating facilities. In the future the power plants of Draukraft in Carinthia will be supervised and controlled remotely from KELAG's central control unit in Klagenfurt, as a result of which the central control unit becomes the primary energy control for Carinthia.

    Helium-cooled divertor concepts are considered suitable for use in fusion power plants for safety reasons, as they enable the use of a coolant compatible with any blanket concept, since water would not be acceptable e.g. in connection with ceramic breeder blankets using large amounts of beryllium. Moreover, they allow for a high coolant exit temperature for increasing the efficiency of the power conversion system. Within the framework of the European power plant conceptual study (PPCS), different helium-cooled divertor concepts based on different heat transfer mechanisms are being investigated at ENEA Frascati, Italy, and Forschungszentrum Karlsruhe, Germany. They are based on a modular design which helps reduce thermal stresses. The design goal is to withstand a high heat flux of about 10-15 MW/m 2 , a value which is considered relevant to future fusion power plants to be built after ITER. The development and optimisation of the divertor concepts require an iterative design approach with analyses, studies of materials and fabrication technologies, and the execution of experiments. These issues and the state of the art of divertor development shall be the subject of this report. (author)

    The cupressaceous genus Tetraclinis is recognized from the Oligocene and Miocene of western North America on the basis of co-occurring seed cones, seeds, and foliage branches. Morphological and anatomical comparisons with the two previously recognized European Tertiary species indicate that the North American specimens are morphologically inseparable from Tetraclinis salicornioides (Unger) Kvacek. The North American taxon is treated as a new variety, T. salicornioides (Unger) Kvacek var. praedecurrens (Knowlton) comb. et stat. nov., and is distinguished from the European representatives, T. salicornioides (Unger) Kvacek var. salicornioides, by slight anatomical differences in the leaf epidermis. Although cones and seeds of the fossil species are closely similar to those of extant Tetraclinis articulata, the foliage is more "spreading," composed of flattened segments with fused facial and lateral leaves that are apparently adaptive for a more mesic climate. The recognition of T. salicornioides in western North America along with the absence of Tetraclinis in the fossil and recent flora of eastern Asia provide evidence for communication of the species across the North Atlantic during the early or middle Tertiary.

    The paper presents a strategy for the market introduction of concentrating solar power (CSP) plants in the Middle East and North Africa (MENA) that will not require considerable subsidization and will not constitute a significant burden for electricity consumers in the region. In the first section, the paper explains the need of MENA countries for sustainable supply of electricity and calculates the cost of electricity for a model case country. In the second part, the cost development of concentrating solar power plants is calculated on the basis of expectations for the expansion of CSP on a global level. After that, the challenges for the market introduction of CSP in MENA are explained. Finally, we present a strategy for the market introduction of CSP in MENA, removing the main barriers for financing and starting market introduction in the peak load and the medium load segment of power supply. The paper explains why long-term power purchase agreements (PPA) for CSP should be calculated on the basis of avoided costs, starting in the peak load segment. Such PPA are not yet available, the paper aims to convince policy makers to introduce them. - Research Highlights: → Concentrating Solar Power in the Mediterranean Region (MED-CSP 2005) (www.dlr.de/tt/med-csp). → Trans-Mediterranean Interconnection for Concentrating Solar Power (TRANS-CSP 2006) (www.dlr.de/tt/trans-csp). → Concentrating Solar Power for Seawater Desalination (AQUA-CSP 2007) (www.dlr.de/tt/aqua-csp). → Risk of Energy Availability: Common Corridors for Europe Supply Security (REACCESS 2009) (http://reaccess.epu.ntua.gr/). → Combined Solar Power and Desalination in the Mediterranean (MED-CSD 2010) (www.med-csd-ec.eu).

    Full Text Available Hydro Electric Power Plant is a power generating system using gravity fall of water as the main force to move the turbine and generate electricity. The construction purpose of Lau Gunung hydropower (2×7. 5 MW that is located in Dairi, North Sumatra, is to Supply power to 14,000 house of the surrounding region. The river run-off system, where the water is immediately contained and then flowed through a tunnel considering the discharge flowing river, where it is constant and does not occur in the fluctuating water level. The Lau Gunung river has the minimum flow that can exceed from 15 to 25 m3/s with a high tunnel dimensions of 4 metres long, 3,9 metres wide and a length of 1,6 kilometres. In terms of the analysis of the time effectiveness of the NATM can be saved because of the continuous work of 24 hours, without any obstacles in which the sub methods used include the drilling & blasting. The tunnel then use the form of steel reinforcement rib and Safety shotcrete lining. The general review may show that using NATM result a tremendous savings, also the use of horse shape conduce small displacement which is effective for the construction.

    In this study, an inexact coupled coal and power management (ICCPM) model was developed for planning coupled coal and power management systems through integrating chance-constrained programming (CCP), interval linear programming (ILP) and mixed integer linear programming (MILP) techniques. The ICCPM model can effectively handle uncertainties presented in terms of probability density functions and intervals. It can also facilitate dynamic analysis of capacity expansions, facility installation and coal inventory planning within a multi-period and multi-option context. Complexities in coupled coal and power management systems can be systematically reflected in this model, thus applicability of the modeling process would be highly enhanced. The developed ICCPM model was applied to a case of long-term coupled coal and power management systems planning in north China. Interval solutions associated with different risk levels of constraint violations have been obtained, which can be used for generating decision alternatives and helping identify desired policies. The generated results can also provide desired solutions for coal and power generation, capacity initiation and expansion, and coal blending with a minimized system cost, a maximized system reliability and a maximized coal transportation security. Tradeoffs between system costs and constraint-violation risks can also be tackled.

    To investigate the relationship between skinfold thickness and body mass index (BMI) in North European Caucasian and East Asian young women with and without anorexia nervosa (AN) in two countries. Height, weight and skinfold thicknesses were assessed in 137 young women with and without AN, in Australia and Singapore. The relationship between BMI and the sum of triceps, biceps, subscapular and iliac crest skinfolds was analysed with clinical status, ethnicity, age and country of residence as covariates. For the same BMI, women with AN had significantly smaller sums of skinfolds than women without AN. East Asian women both with and without AN had significantly greater skinfold sums than their North European Caucasian counterparts after adjusting for BMI. Lower BMI goals may be appropriate when managing AN patients of East Asian ancestry and the weight for height diagnostic criterion should be reconsidered for this group.

    Gender inequality is a long-recognized driver of the HIV epidemic. However, few studies have investigated the association between gender-based power and HIV risk in India, which has the world's third largest HIV epidemic. Population-based data collected in 2003 from 3,385 couples residing in Uttar Pradesh and Uttarakhand, North India, were used to examine associations between gender-based power (wife's autonomy and husband's inequitable gender attitudes) and indicators of couples' HIV risk (whether the husband had had premarital sex with someone other than his eventual spouse, extramarital sex in the past year or STI symptoms in the past year). Structural equation modeling was used to create composite variables for the gender-based power measures and test their associations with HIV risk measures. Twenty-four percent of husbands had had premarital sex, 7% had had extramarital sex in the past year and 6% had had STI symptoms in the past year. Structural equation models indicated that wives who reported higher levels of autonomy were less likely than other wives to have husbands who had had extramarital sex in the past year (direct association) or STI symptoms in the past year (indirect association). Moreover, husbands who endorsed more inequitable gender attitudes were more likely than others to report having had premarital sex with someone other than their spouse, which in turn was associated with having had extramarital sex and STI symptoms in the past year. If the associations identified in this study reflect a causal relationship between gender-based power and HIV risk behavior, then HIV prevention programs that successfully address inequitable gender roles may reduce HIV risks in North India.

    Bio-oil (biomass fast pyrolysis) systems for heat, power or CHP production are nearing demonstration status. Their commercial attractiveness will depend on many factors, and will vary with the application, the scale, and importantly the location and its associated economic and logistical factors. The objective of this work, carried out as part of an EC-ALTENER project, was to evaluate the opportunities for bio-oil in the heat and power markets of Europe. Bio-oil applications were compared with conventional (fossil) alternatives for the same heat and power duty. The evaluation was carried out by a quantitative assessment of the economic competitiveness of standard applications in 14 European countries. Location-specific data were collected, and combined with technology-specific data obtained from earlier work. A competitiveness factor (c F ) was derived which represents the total annual cost of a conventional alternative relative to a bio-oil application. The results showed a wide variation across Europe. A total of six countries had at least one bio-oil application which was economically competitive. Heat-only applications were found to be the most economically competitive, followed by CHP applications, with electricity-only applications only very rarely competitive. For a given technology, the larger the scale, the better the competitiveness

    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.

    Full Text Available The European Union encourages and institutionalizes participation by environmental, consumer, and labor organizations in the governance of nanotechnology. Interviews with leaders of the civil society organizations (CSOs show that they identified multiple problems with nanotechnology policy but had only limited success in gaining the changes that they sought. CSO leaders explain their lack of success as due to the overwhelming power of industry and the support of the European Commission for new industrial development, including nanotechnology. We analyze the perspectives of CSO leaders about their difficulties to develop the theory of the political opportunity structure in the situation of a highly scientized policy field with strong industrial monitoring. We suggest the need to extend the theory to pay more attention to the strategies that reformers can use to maneuver in and to open a relatively closed political opportunity structure. We argue that formal stakeholder engagement is not very effective and suggest instead the importance of the following: building coalitions with government actors, threatening or mobilizing grassroots mobilization, making the issue salient to the public, and pursuing the full range of institutional repertoires.

    Full Text Available Confronting an increasing EU opposition from a number of influential member states to its membership the AKP government adopted a multilateral approach to its foreign policy making resulting in dynamic economic and diplomatic policies with the countries from Asia, Africa, Latin America, and the Balkans region. In this article we analyzed the effects and consequences of a paradigmatic shift in Turkish foreign policy in the Western Balkans in relation to the country's EU membership prospects. Through its pro-active economic and diplomatic initiatives in the region Turkey has been proving itself as indispensable country for the European Union membership. Thus, if the Turkish government concentrates more on solving its internal problems and continues its pro-active diplomacy in Western Balkans, among other regions, it could become not only a regional but also a global power.

    The Safety and Environmental Assessment of Fusion Power (SEAFP) project was set up by the European Community Fusion Programme in response to recommendations made by a high level Fusion Programme Evaluation Board. The Evaluation Board stated that fusion potentially possesses ''inherent environmental and safety advantages over all current alternatives for base load electricity generation'', but that a ''convincing demonstration'' of these potential advantages is necessary. SEAFP is undertaken by three main participants: the NET Team, The Euratom/UKAEA Association, and European industry. Other EC fusion laboratories also participate. The work embraces the outline design of fusion power stations, the safety and environmental assessment of those designs, and interactions between design and assessment to improve the design. The project began in April 1992 and will report in December 1994. In the first year of the project, five candidate blanket concepts were developed in parallel. Other aspects of design were developed as far as possible independently of the blanket designs. Assessments were made of the technical merits of the candidate designs, and scoping calculations were used to provide preliminary assessments of their accident and waste management characteristics. Accident identification studies were used to select the bounding sequences to be analysed later in detail. Targets for safety and environmental performance were developed. This phase of the study culminated, in August 1993, in the selection of two plant models, one based on a water/martensitic steel/lithium-lead blanket, the other based on a helium/vanadium alloy/lithium oxide blanket, to be developed and assessed in more detail. Other design variants will be assessed through sensitivity studies. ((orig.))

    Nature reserves are created to keep in their original states natural environment, flora and fauna of various ecological systems, territories, climatic zones, etc. Now natural objects everywhere exist under anthropogenic loading from man-made activities. It is impossible to avoid atmospheric or river transport of pollution to the environment of reserved territories. The main idea of the work is to analyze atmospheric transport of anthropogenic metals (Ni, Cu, Pb, Fe, Al), as well as of soot (black carbon - BC) from Russian large industrial areas (source-regions) to the territories of nature reserves at the North of European Russia - the Kostomukshsky reserve (KR) in Karelia (64.57°N, 30.67°E) and the Nenetzky reserve (NR) at the Pechora River mouth (68,5°N, 53,5°E). The basic data for these 2 points were back trajectories of air mass transport calculated for every day of January, April, July, and October during 10 years from 2001 to 2010. We used NCEP/NCAR Reanalysis Data Files with HYSPLIT 4 model and two approaches for analyzing the trajectories. The main source-regions were chosen for each reserve. The annual source emissions for the last decade are generalized from the data published by Roshydromet of Russia (http://www.nii-atmosphere.ru/files/PUBL/Eg_2008.doc). The deposition velocity was a sum of dry and wet components. The equal values of deposition velocities onto the surface were assumed for all impurities because they are mainly on submicron aerosol particles under atmospheric transport for a long distance. The seasonal and spatial variations of averaged deposition velocity were accounted in accordance with surface properties and precipitation regimes. As a result, the maximal air concentrations of aerosol pollutants are observed in cold seasons, whereas the maximal fluxes onto the surface occur in warm period. Thus, it's possible that the cleanest air does not indicate the same surface. Fe and Al are the crust (dust or soil) elements. Thus, their main

    High energy demand has necessitated search for all possible sources of energy. Conventional energy source is having negative impact on our environment, therefore our attention is focused on renewable energy sources, such as solar, wind, hydro, which are considered to be clean and sustainable energy sources. India has set an ambitious target of producing 175 GW of energy using solar energy. Therefore, it is necessary to estimate the solar potential to observe the feasibility of such project. North-east India is an underdeveloped region of India and due to its geographical location and difficult terrain, many regions are still not electrified. Such regions can be electrified by installing renewable energy based power plants, which can also generate number of jobs hence improving the quality of life and economic condition of the region. The objective of this paper is to estimate the solar power potential of Silchar (Assam, India) and perform a feasibility study for installation of solar-based power plant in the region. In this paper, solar radiation on tilted surface is estimated by using an anisotropic sky model. This radiation data has been used to estimate the PV power output. Finally, feasibility of the PV plant has been verified by mapping with a practical load demand.

    All of the North African countries have plans to develop nuclear power. If successful, nuclear energy could supply up to 9-15% of all electricity consumption in the region by 2030. How realistic are these plans and under what conditions can they be implemented? This paper seeks to answer this question by analyzing the motivations and capacities for deploying nuclear energy in the five North African countries by examining both regional and national factors. These factors are compared to similar characteristics of the countries with existing nuclear power programs using a series of quantitative indicators. While all five countries have strong motivations to develop nuclear power, which result from the high growth rates in demand for electricity and energy security concerns, their financial and institutional capacities to deploy nuclear energy vary and are generally lower than in those countries which already operate nuclear power plants. Most likely, North Africa will need to rely on external assistance to implement its nuclear energy plans. The article identifies three scenarios of nuclear power development from the interplay between internal and external factors, particularly the success of renewable energy projects and the ability to attract international investment in nuclear power. - Research Highlights: → Nuclear power is an option to diversify electricity and meet demand in N. Africa. → With current plans, nuclear power could generate up to 15% of electricity by 2030. → Capacities in N. Africa are insufficient to launch nuclear power programs. → Deployment of nuclear power in N. Africa depends on external assistance and investment.

    Cucumber (Cucumis sativus L.), a widely cultivated crop, has originated from Eastern Himalayas and secondary domestication regions includes highly divergent climate conditions e.g. temperate and subtropical. We wanted to uncover adaptive genome differences between the cucumber cultivars and what sort of evolutionary molecular mechanisms regulate genetic adaptation of plants to different ecosystems and organism biodiversity. Here we present the draft genome sequence of the Cucumis sativus genome of the North-European Borszczagowski cultivar (line B10) and comparative genomics studies with the known genomes of: C. sativus (Chinese cultivar--Chinese Long (line 9930)), Arabidopsis thaliana, Populus trichocarpa and Oryza sativa. Cucumber genomes show extensive chromosomal rearrangements, distinct differences in quantity of the particular genes (e.g. involved in photosynthesis, respiration, sugar metabolism, chlorophyll degradation, regulation of gene expression, photooxidative stress tolerance, higher non-optimal temperatures tolerance and ammonium ion assimilation) as well as in distributions of abscisic acid-, dehydration- and ethylene-responsive cis-regulatory elements (CREs) in promoters of orthologous group of genes, which lead to the specific adaptation features. Abscisic acid treatment of non-acclimated Arabidopsis and C. sativus seedlings induced moderate freezing tolerance in Arabidopsis but not in C. sativus. This experiment together with analysis of abscisic acid-specific CRE distributions give a clue why C. sativus is much more susceptible to moderate freezing stresses than A. thaliana. Comparative analysis of all the five genomes showed that, each species and/or cultivars has a specific profile of CRE content in promoters of orthologous genes. Our results constitute the substantial and original resource for the basic and applied research on environmental adaptations of plants, which could facilitate creation of new crops with improved growth and yield in

    Developments between 2004 and 2006 indicate that a North European Gas Pipeline (NEGP) through the Baltic Sea, from Russia to Germany, may be realised in the coming decade. This would provide Europe with yet another opportunity to diversify its import channels of gas. It is however reasonable to assume that the NEGP also could change the strategic pattern and be a source of friction. The NEGP may rock the regional stability and reduce the potential of the new EU members to become security providers in Europe's northern dimension. It also gives increased leverage and influence to Russia, a state that has moved in an authoritarian direction under President Putin. The aim of this pilot study is to elucidate on the NEGP pipeline and Sweden's increasing dependence on Russian energy. A subsidiary aim is to outline a set of concerns that have bearing on the situation for the EU and Baltic Sea Region and that need to be further addressed. In conclusion, the NEGP will enhance Russia's direct leverage on Poland, Ukraine, and Belarus, as it will allow Russia to turn off gas supplies without affecting exports to other parts of Europe. Russia will also increase its leverage over the states that will or may be connected to the NEGP (Germany, and possibly Belgium, Denmark, the Netherlands and the UK). Even if Sweden is not embracing the NEGP, it is today highly sensitive as it imports most of its energy. It is increasingly dependent on Russian oil and is partly dependent on imports of electricity from Russia. Should the NEGP materialise and Sweden becomes connected in the future, it would likely be dependent also on natural gas. It is of paramount importance for the energy security of the connected states how the pipeline is constructed and operated. If there will be technical possibilities for Russia to tamper with the flow of gas to individual states without affecting supply to others, there are tangible threats to the importing states.

    Today honey bees, principally the western honey bee, Apis mellifera, represent a multi-billion dollar agricultural industry. Through the efforts of humans they have become established well outside of their modern native ranges, having been introduced multiple times into the Americas, Australia, New Zealand, New Caledonia, and many areas of Oceania. The native, i.e., non-human influenced, distribution and migration of honey bee species and populations has been a matter of serious and continued debate. Apicultural dogma informs us that the center of origin of honey bees (genus Apis) resides in Asia, with subsequent migration and diversification into Europe and Asia. Recent population genetic studies of the western honey bee, Apis mellifera, slightly modified this received wisdom by suggesting that this species originated in Africa and subsequently reinvaded Eurasia. Research into the historical biogeography of honey bees has ignored entirely the abundant fossil evidence distributed through a variety of Late Paleogene (Oligocene) and Early Neogene (Miocene) deposits, a diversity which is predominantly European in origin, particularly among the most basal species of the genus. We have examined the morphological disparity and affinities of the full living and fossil diversity of honey bees ranging from their earliest origins to the present day. This analysis indicates that honey bees exhibited a greater morphological disparity during the Oligocene and Miocene epochs, a time when the principal lineages were established, and that Apis apparently originated in Europe, spreading from there into Asia, Africa, and North America, with subsequent diversification in the former two regions and extinction in the latter. During the human migrations and colonization honey bees were once again introduced multiple times into the Americas, as well as into Australia and Asia.

If there will be technical possibilities for Russia to tamper with the flow of gas to individual states without affecting supply to others, there are tangible threats to the importing states

    Dyslipidemia is reported in 27 - 43% of children and adolescents with overweight/obesity and tracks into adulthood, increasing the risk of cardiovascular morbidity. Cut-off values for fasting plasma lipid concentrations are typically set at fixed levels throughout childhood. The objective of this cross-sectional study was to generate fasting plasma lipid references for a Danish/North-European White population-based cohort of children and adolescents, and investigate the prevalence of dyslipidemia in this cohort as well as in a cohort with overweight/obesity. A population-based cohort of 2141 (1275 girls) children and adolescents aged 6 - 19 (median 11.5) years was recruited from 11 municipalities in Denmark. Additionally, a cohort of children and adolescents of 1421 (774 girls) with overweight/obesity aged 6 - 19 years (median 11.8) was recruited for the study. Height, weight, and fasting plasma lipid concentrations were measured on all participants. Smoothed reference curves and percentiles were generated using the Generalized Additive Models for Location Scale and Shape package in the statistical software R. In the population-based cohort, plasma concentrations of total cholesterol (TC) (P dyslipidemia was 6.4% in the population-based cohort and 28.0% in the cohort with overweight/obesity. The odds ratio for exhibiting dyslipidemia in the cohort with overweight/obesity compared with the population-based cohort was 6.2 (95% CI: 4.9 - 8.1, P dyslipidemia.

    Since July 2014 the interstate standard GOST 32144-2013 is the only document that defines standard requirements for the power quality in the territory of the Russian Federation. The new standard preamble specifies that this document considers the requirements of the European regional standard EN 50160-2010. However, GOST authors established the degree of standards conformity as nonequivalent. In connection with Russia's accession to the World Trade Organization (WTO) all requirements for goods including electric energy should correspond the international standard requirements. The article analyzes the above standard requirements and assesses the requirements for the power quality standards used in the European Union and in the Russian Federation.

    European countries of nuclear power phase-out have changed to commit to the future of nuclear energy due to the intended low-carbon power, the energy security concerns and the need of replacement reactors as current reactors approach the end of operating lives, as Italian government has passed legislation to build new nuclear power plants. This article described the perspective of nuclear power policy changes in UK, Italy an Sweden and the business trend and the SWOT analysis of related electric utilities (EDF, Enel and Vattenfall) and nuclear industries (Areva NP, Sheffield Forgemasters, ENSA and Studsvik). Policy implications obtained from this analysis were commented for Japanese nuclear industry activities. (T. Tanaka)

    This conference offered an opportunity to review energy markets in North American with particular reference to opportunities for traditional technologies and new generation technologies based on renewable energy sources including wind powered generation. The presentations focused on relative fuel prices and the potential for distributed generation and demand side management. Several presentations examined the issue of why Canadian and North American markets remain divided about the best market design and how to ensure reliability. The 6 sessions were entitled: the future of generation in Canada; wind power opportunities and constraints; new business opportunities for distributed power and demand side management; the future of restructuring in North America; reliability; and, the future of restructuring in Alberta. tabs., figs

  6. Opting out of the peaceful use of nuclear power in Germany. A promising special approach in the European context?

    Nuclear power is in the focus of politics and public attention in Germany not only because of the federal elections. Again and again, voices are heard which doubt the decision taken in 2000 to opt out of the use of nuclear power. The change in parliamentary majority in favor of the alliance of CDU/CSU and FDP as a result of the elections on September 27 is leading to another review of the opt-out decision, as the three parties in their platforms expressed themselves in favor of extending nuclear power plant life. This makes a stocktaking exercise of all salient arguments imperative at the present juncture. The perspective in that case should not be restricted to national aspects but include especially the influence of the European dimension of the subject. Present political positions in the 27 EU countries indicate a renaissance of nuclear power. Numerous countries, such as Italy, Sweden, Poland or the United Kingdom, revoked their historic opt-out decisions, are using nuclear power for the first time, or want to expand greatly the nuclear share in their electricity generation mix. All 3 European agencies with clear majorities advocate the extensive use of nuclear power as a long-term component of the mix of energy resources. Germany, with its decision to opt out of the use of nuclear power, is part of a minority. Being part of a European electricity market which will grow together more and more closely up to complete integration, Germany will always be supplied electricity from nuclear sources in the long run. This will be true irrespective of nuclear power plants being operated in the country. So, shutting down German nuclear power plants will not achieve the goals of nuclear opponents but merely give rise to additional challenges in power technology in an effort to ensure Germany's electricity supply. For this reason, the new German federal government should revoke the decision to opt out of the peaceful use of nuclear power. (orig.)

  7. Integration of renewable energies and nuclear power into North African Energy Systems: An analysis of energy import and export effects

    2011-01-01

    The North African countries Morocco, Algeria, Tunisia, Libya and Egypt have been and are currently experiencing rapid growth in energy demand. This development confronts their political leaders with the question of how to expand or diversify their countries' generation capacities. In this context, renewable energies and nuclear power constitute options that have rarely been exploited so far in the region. This article analyzes the drawbacks and benefits of both alternatives, with a special focus on import and export dynamics. When attempting to make the strategic decision between renewables and atomic power, North African regional specifics and circumstances have to be taken into account. Hence, in a first step, the article characterizes the energy systems of the North African countries and presents scenarios for their future development. In a second step, it scrutinizes the energy challenges these states face in terms of domestic concerns and foreign affairs. Finally, a case study of Algeria is used to demonstrate how renewable energies, but not nuclear power, are able to respond to North African energy challenges. - Research highlights: → Using nuclear power would require fuel imports over the entire operation time. → Hence, energy exporters (Algeria, Libya) would become dependent on fuel imports. → Renewable energies can make North African countries less fuel import dependent. → Nuclear technologies would have to be imported over the whole life cycle of plants. → Domestic production for renewables technologies could be established after a first phase of technology imports.

  8. Finance considerations relating to power station construction from the viewpoint of a European banker

    The energy industry in the European Community is outlined in brief in the first section. It includes a description of the structure and organization of the various companies operating power stations, featuring such keywords as centralized-decentralized and shareholding. The general considerations of the banking sector are then dealt with. From the banker's point of view, the risk factor of a loan depends on whether the load is to be used for the financing of a brand new power station based either on fossil fuels, nuclear power or alternative sources of energy or whether the load is to be used for modernization purposes. In this respect the credit rating of the borrower, including shareholders, profitability, capital investment volume in relation to company size, project risk and methods of furnishing security shall be discussed. Having dealt with these basic questions, the specific factors relating to financing for modernization purposes are examined. A distinction must be made between voluntary and mandatory modernization measures. The assessment of modernization required by law is generally based on whether the mandatory standards an be fulfilled by investing the least possible expenditure. On the other hand, the banker assesses voluntary modernization mainly in light of the resulting effects on the financial standing of the borrower. If satisfactory results are achieved from the examination of these points, the question of security must be considered when evaluating the residual exposure. All considerations culminate in the selection of the appropriate form of financing. In addition to the traditional bank loan and project financing, government support and special forms of financing are also discussed

    Despite the recognition of power as being central to health research collaborations between high income countries and low and middle income countries, there has been insufficient detailed analysis of power within these partnerships. The politics of research in the global south is often considered outside of the remit of research ethics. This article reports on an analysis of power in north-south public health research, using Zambia as a case study. Primary data were collected in 2011/2012, through 53 in-depth interviews with: Zambian researchers (n = 20), Zambian national stakeholders (n = 8) and northern researchers who had been involved in public health research collaborations involving Zambia and the global north (n = 25). Thematic analysis, utilising a situated ethics perspective, was undertaken using Nvivo 10. Most interviewees perceived roles and relationships to be inequitable with power remaining with the north. Concepts from Bourdieu's theory of Power and Practice highlight new aspects of research ethics: Northern and southern researchers perceive that different habituses exist, north and south - habituses of domination (northern) and subordination (Zambian) in relation to researcher relationships. Bourdieu's hysteresis effect provides a possible explanation for why power differentials continue to exist. In some cases, new opportunities have arisen for Zambian researchers; however, they may not immediately recognise and grasp them. Bourdieu's concept of Capitals offers an explanation of how diverse resources are used to explain these power imbalances, where northern researchers are often in possession of more economic, symbolic and social capital; while Zambian researchers possess more cultural capital. Inequities and power imbalances need to be recognised and addressed in research partnerships. A situated ethics approach is central in understanding this relationship in north-south public health research.

    The state of affairs in the North American energy markets was discussed. Significant changes are taking place in the energy industry at a greater pace than ever before. These changes include more strategic alliances, mergers, acquisitions and name changes. This paper also discussed the issue of climate change and how it will effect business operations in the energy industry in the next millennium. It was suggested that climate change should be viewed as a business issue. Marketing 'green power' will become a significant business tool in the next century. The role that natural gas will play in new business opportunities was also discussed. Future gas supply and demand forecasts indicate that there is enough natural gas to last well into the twenty second century. Natural gas prices are not expected to climb high enough to deter its use. The future for natural gas looks promising

    Dr. Rita Colwell, director of the U.S. National Science Foundation (NSF), and Dr. Catherine Cesarsky, director general of the European Southern Observatory (ESO), today signed a historic agreement jointly to construct and operate ALMA, the Atacama Large Millimeter Array, the world's largest and most powerful radio telescope operating at millimeter and sub-millimeter wavelengths. "With this agreement, we usher in a new age of research in astronomy," said Dr. Colwell. "By working together in this truly global partnership, the international astronomy community will be able to ensure the research capabilities needed to meet the long-term demands of our scientific enterprise, and we will be able to study and understand our Universe in ways that have previously been beyond our vision."

Representing Europe, and in collaboration with many laboratories and institutes on this continent, we together look forward toward wonderful research projects. With ALMA, we may learn how the earliest galaxies in the Universe really looked like, to mention but one of the many eagerly awaited opportunities with this marvelous facility." When complete in 2011, ALMA will be an array of 64, 12-meter radio antennas that will work together as one telescope to study millimeter and sub-millimeter wavelength light from space. These wavelengths of the electromagnetic spectrum, which cross the critical boundary between infrared and microwave radiation, hold the key to understanding such processes as planet and star formation, the formation of early galaxies and galaxy

    The transition of the European power system from fossil generation towards renewable sources is driven by different reasons like decarbonisation and sustainability. Renewable power sources like wind and solar have, due to their weather dependency, fluctuating feed-in profiles, which make their system integration a difficult task. To overcome this issue, several solutions have been investigated in the past like the optimal mix of wind and PV [1], the extension of the transmission grid or storages [2]. In this work, the optimal distribution of wind turbines and solar modules in Europe is investigated. For this purpose, feed-in data with an hourly temporal resolution and a spatial resolution of 7 km covering Europe for the renewable sources wind, photovoltaics and hydro was used. Together with historical load data and a transmission model , a simplified pan-European power power system was simulated. Under cost assumptions of [3] the levelized cost of electricity (LCOE) for this simplified system consisting of generation, consumption, transmission and backup units is calculated. With respect to the LCOE, the optimal distribution of generation facilities in Europe is derived. It is shown, that by optimal placement of renewable generation facilities the LCOE can be reduced by more than 10% compared to a meta study scenario [4] and a self-sufficient scenario (every country produces on average as much from renewable sources as it consumes). This is mainly caused by a shift of generation facilities towards highly suitable locations, reduced backup and increased transmission need. The results of the optimization will be shown and implications for the extension of renewable shares in the European power mix will be discussed. The work is part of the RESTORE 2050 project (Wuppertal Institute, Next Energy, University of Oldenburg), that is financed by the Federal Ministry of Education and Research (BMBF, Fkz. 03SFF0439A).

    2009-01-01

    The DISCO test facility at Forschungszentrum Karlsruhe (FZK) has been used to perform experiments to investigate direct containment heating (DCH) effects during a severe accident in European nuclear power plants, comprising the EPR, the French 1300 MWe plant P'4, the VVER-1000 and the German Konvoi plant. A high-temperature iron-alumina melt is ejected by steam into scaled models of the respective reactor cavities and the containment vessel. Both heat transfer from dispersed melt and combustion of hydrogen lead to containment pressurization. The main experimental findings are presented and critical parameters are identified. The consequences of DCH are limited in reactors with no direct pathway between the cavity and the containment dome (closed pit). The situation is more severe for reactors which do have a direct pathway between the cavity and the containment (open pit). The experiments showed that substantial fractions of corium may be dispersed into the containment in such cases, if the pressure in the reactor coolant system is elevated at the time of RPV failure. Primary system pressures of 1 or 2 MPa are sufficient to lead to full scale DCH effects. Combustion of the hydrogen produced by oxidation as well as the hydrogen initially present appears to be the crucial phenomenon for containment pressurization.

    1983-01-01

    The report covers operational nuclear power stations of capacity greater than 5C MWe and nucler fuel reprocessing plants in the European Community. Radioactive gaseous and liquid effluent discharges from these installations are given for the period 1976 to 1980, expressed both in absolute terms and normalized to net electricity production from the fuel. An assesssment is then made of exposure of members of the public consequent to the 1980 discharges. Where environmental contamination levels were detectable the results have been taken into account in the dose assessment; however, environmental contamination was in general below the limit of detection. In these circumstances the dose estimates rely entirely on theoretical models which frequently incorporate conservative assumptions; hence these estimates are likely to be greater than the doses actually received. The estimated exposures have then been compared with the dose limits set out in the Euratom Directive of 15th July, 1980. It is concluded that the exposure of members of the public always left an appreciable safety margin relative to the limits and indeed lay within the variations in exposure which result from natural background

  19. Radioactive effluents from nuclear power stations and reprocessing plants in the European Community

    International Nuclear Information System (INIS)

    1978-04-01

    The report presents the available data on radioactive gaseous and liquid effluents discharged by nuclear power stations and nuclear fuel reprocessing plants in the European Community from 1972 to 1976. Discharges are expressed both in absolute terms and relative to the net production of electricity from the fuel. On the basis of the discharges recorded for 1976 the resulting maximum exposure of members of the population is quantified and compared with the dose limits prescribed by Euratom radiological protection standards and with the exposure resulting from natural radioactivity. It is concluded that there is no case in which a discharge could have given rise to an exposure exceeding the relevant prescribed limit. Not only did the possible maximum exposures incurred by individuals leave an appreciable safety margin relative to that limit but, for the vast majority of installations, they were comparable with or were considerably lower than the geographical and temporal variations in exposures resulting from natural radioactivity. Where environmental levels have been detectable the measured results have of course been used but, with few exceptions, the levels have remained less than the very low limits of detection currently possible. In general, where theoretical models are used to evaluate exposure, they are designed to give conservative results and hence it is likely that the true exposures are even less than those calculated

    When the European Commission`s Directorate for Energy (DG XVII) opened the second application window for THERMIE proposals under the Fourth Framework Programme on September 15, 1995, Europe`s solar thermal power community discovered a remarkable modification to the previous call for proposals. For the first time since solar thermal electricity was introduced for THERMIE demonstration projects, it now became eligible for EU financial support. Right now, the European Commission committed funding for the design and engineering phase of the THESEUS project implementation. (orig.)

    Sixteenth- and seventeenth-century European blue glass trade beads from aboriginal sites in the eastern Great Lakes area of North America have been analysed non-destructively using low neutron dose instrumental neutron activation analysis, so that the beads could be returned to their keepers. Dark blue (cobalt-coloured) beads are readily separable from turquoise (copper-coloured) beads. Differences in the chemistries of the turquoise blue beads appear to be useful in separating glass beads from the two centuries. Low calcium, sixteenth-century turquoise beads tend to disintegrate by a leaching of the alkali metals. (Author)

    2007-01-01

    The European Concerted Action for Offshore Wind Energy Deployment (COD) was carried out by eight sea-bordering European Union member states, with the objective to remove not explicitly technical barriers to offshore wind energy. Within the COD, an inventory of relevant aspects affecting the grid integration of offshore wind energy on a large scale in the eight countries has been made. Collected data items for this inventory are national plans and prospects for offshore wind energy, information about the transmission system, possibilities for grid connection, aspects of the grid codes, balancing, connection and energy pricing. The comprehensive COD reports were published and presented in October 2005 during the Copenhagen Offshore wind conference. This paper provides a short description of the situation for each country. Thereafter, country-specific information is grouped based on geography and membership in a synchronous zone. Additionally, a view is developed on the desirable facilities for the trans-European exchange of power from large wind farms. Finally, we elaborate overall conclusions in order to arrive at generalized observations, recommendations for policy makers and issues that will emerge in the near future. As a general conclusion, many things need to be done on a technical level in order to integrate large amounts of offshore wind power into our power systems. However, none of these measures is technically unknown. Therefore, the feasibility of integrating large amounts of offshore wind power is mainly a question of finance and hence based on political decisions. (Author)

    2005-07-01

    This paper presents a static computational game theoretic COMPETES model. This model is used to study the economic and environmental effects of the liberalisation of the European electricity market. The COMPETES model takes strategic interaction into account. The model is calibrated to four European countries: Belgium, France, Germany and the Netherlands. To analyse the impact of emission trading, a fixed permit price per tonne CO2 emissions is introduced. The effects are studied under different market structures depending on the ability of firms to exercise market power. The results indicate that the effects of liberalisation depend on the resulting market structure, while a reduction in market power of large producers may be beneficial for the consumer (i.e. lower prices), this is not necessarily true for the environment (i.e. lower reduction in CO2 emissions)

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

    If one speaks of electric power prices and price control in the year 1992, this subject has a different dimension than it did two or three years ago, when the new federal rate scale for electric power (ETO Elt) was drawn up and put into practice. Since the beginning of this year, a draft for guidelines which was drawn up by the EC Commission exists which, going on the assumption that the European domestic electric power market will set an example, does away with territorial protection and in the name of third party access (TPA) allows for electric power-line transit, thus introducing at least partial competition to the electric power market. We no longer think in terms of closed systems with clear-cut responsibilities in regard to power supply, which form the basis for the laws on electric power prices, the cartel laws, the practices of the electric power control board and the cartel authorities. Thus, using the new federal rate scale for electric power and its principles as formulated in Article 1 as a point of departure, developments will go in the direction of a competitive system in accordance with the ideas of the EC Commission and German free-enterprise theoreticians, as laid down for example by the deregulation commission. Thus developments will lead us away from the status quo in the direction of possible reforms, if not to say revolutionary structural changes and the consequnces which they will bring for price and cartel laws.

    Against the background of an increasing importance of climate change mitigation and the liberalization of the European energy supply this study assesses the perspectives of power plants with Carbon dioxide Capture and Storage (CCS). CCS power plants represent one option to reduce CO 2 emissions of fossil energy based electricity production significantly. In this study the deployment of CCS power plants is investigated for the European electricity market until 2050 taking different energy and climate policy framework conditions into consideration. By applying an integrated model-based approach, structural changes of the whole energy system are incorporated, including their implications on costs and emissions. The study addresses uncertainties concerning future CCS power plant invest costs and efficiencies explicitly, and analyses the effects of changes of these parameters with respect to the perspectives of CCS power plants in Europe. Thereby, interdependencies on horizontal level related to competition of different technologies within the electricity sector are examined, but also vertical interdependencies resulting from effects between the upstream and energy demand sectors. In order to reflect the heterogeneity among the national energy systems in Europe, country specific particularities on technical aspects and energy policy are taken into account, such as potentials and costs of CO 2 storage, and national regulations on the use of nuclear power and renewable energy. The results of the analysis reveal a strong influence of the stringency of the EU greenhouse gas reduction target and the policy on the use of nuclear energy on the perspectives of CCS power plants in the European electricity market. Comparing the influence of different policy frameworks analysed in this study with the influences of the variation of the technical and economic CCS power plant parameters shows, that uncertainties concerning energy policy measures can have a stronger influence on the

  10. The role of power exchanges for the creation of a single European electricity market: market design and market regulation

    The electricity sector worldwide is undergoing a fundamental transformation of its institutional structure as a consequence of the complex interactions of political, economic and technological forces. The way the industry is organized is changing from vertically integrated monopolies to unbundled structures that favor market mechanisms. This process in Europe, known as the liberalization process, has had a wide impact on the European electricity industry. The focus of this dissertation is an analysis of the role of electricity power exchanges in the recently liberalized electricity markets of Europe. In the context of creating a competitive electricity market at a European level, the key questions considered are the functioning of these power exchanges with respect to electricity characteristics, market design and regulatory framework. In Europe, very little attention has been paid to the role of these new marketplaces and to the issue of market design in general. Hence the main purpose of this work was to analyze how these marketplaces facilitate the trading of electricity and the role they can play in the construction of a pan-European competitive electricity market. An analysis of power exchange requires taking into account the 'double-duality' of such institutions. One, power exchanges are both a market and an institution. As a market they facilitate the trading of electricity and determine an equilibrium price. As an institution power exchanges have their own objectives and constraints, and play a role in the market design of the overall electricity market. Two, the relationship between electricity power exchanges and liberalization is neither linear nor one way: liberalization encourages the birth of such marketplaces yet marketplaces are more than the results of such process, they are also a driving force of the liberalization process. This thesis is divided into three parts. The current situation in Europe and different existing theoretical approaches in

    Along with hydroelectric, wind power is today's major and expanding producer of electricity from renewable sources. So far mainly coastal locations have been used around Europe, and potential for expansion lies especially in places which until now have been used little or not at all. The European Commission White Paper states: ''In particular, there is enormous potential for offshore wind farms [..] In order to achieve large-scale penetration of wind energy in the European Union these areas have also to be used.'' However, other location factors and technical challenges on the open sea demand very careful and thorough planning. As early as 1991, 11 450-kW wind turbine generators came into operation in the Vindeby offshore wind park in Denmark. The Tun diameter Knob park followed in 1995 with 10 500-kW units. By contrast, no wind park is expected to be operating off the coast of Germany until 2005. All around the North Sea and the Baltic Ring, plans are being laid to erect offshore wind power facilities - but in many places the legal and technical framework conditions are the subject of scrutiny on criteria of nature conservation and suitability for the location. The 'Wind Power goes Offshore' seminar presents current planning in Denmark, Sweden, Poland and Germany. There will be reports on experiences with running existing plants, and on procedures for setting up new projects. The seminar and concurrent exhibition were intended to stimulate wide exchanges of information and networking between practitioners at European level. The seminar was for manufacturers, planners and operators of wind power plants, environmental and nature conservation organisations, local authorities, and energy supply companies around the North Sea and the Baltic Ring.

    Competition is an indispensable prerequisite of evolution. In the sector of electricity supply it is defined, inter alia, by the choice of source of primary energy. On the other hand, opening of the European market entails new challenges. In many European countries, electric energy is converted at less expense than in Germany. The builders of capital intensive power grid systems are trying to protect themselves against their competitive chances deteriorating also by their being required to make these grid systems available to competitors not having to bear these expenses. Nuclear power plants are among the most capital intensive generating units in the power industry. However, operating them is not only a matter of the power utilities; to them, nuclear power is one tpye of primary energy out of many others. Instead, the government must indicate the direction, through its energy policy, in which future technologies are to create international competitive advantages to domestic industries. In addition, the government must provide the funds necessary in the launching phase. (orig.) [de

    The Prince Edward Island Energy Corporation, Edmonton Power, Energy, Mines and Resources Canada and the Canadian Electrical Association commissioned a study to understand how electrical power and district heat from combined heat and power (CHP) plants is priced in Europe. Four northern European countries were investigated, Denmark, Germany, Sweden and Finland. These countries produce 45.8 TWh of power from combined heat and power plants, 7.1% of their annual consumption. In the case of Denmark, CHP accounts for 37.5% of its total power production. The energy situation in each country is reviewed using published statistics, and in particular the rapidly changing situation with regard to environmental and fuel taxes is examined. In order to obtain practical insights with regard to tariffs used by the various utilities, a series of generic examples were examined, supported by specific case studies. Technologies reviewed included: CHP from coal-fuelled extraction plant, CHP from coal-fuelled back pressure plant, waste heat from a municipal waste plant, and gas turbine with waste heat recovery. The benefits and risks associated with different tariff designs are discussed in detail including tariff formulae. This should enable interested parties to develop appropriate tariffs for combined heat and power plants in the context of current electrical utility policies. As a complement to the tariffs for combined heat and power plants, the design of district heating tariffs is also addressed. The typical concepts used in different countries are presented and discussed. 23 tabs

    Water-soluble organic compounds (WOCs) and their single components, i.e. low-molecular organic acids, alcohols, and carbohydrates, attain a great deal of attention among soil scientists. WOCs are an important component of soil organic matter (SOM) and form as a results of different biological and chemical processes in soils. These processes are mainly responsible for formation and development of soils in aboveground ecosystems. The purpose of the work was identifying qualitative and quantitative composition of low-molecular organic substances which form in podzolic loamy soils against natural reforestation after spruce forest cutting. The studies were conducted on the territory of the European North-East of Russia, in the middle taiga subzone (Komi Republic, Ust-Kulom region). The study materials were soil of undisturbed bilberry spruce forest (Sample Plot 1 (SP1)) and soils of different-aged tree stands where cutting activities took place in winter 2001/2002 (SP2) and 1969/1970 (SP3). Description of soils and vegetation cover on the plots is given in [1]. Low-molecular organic compounds in soil water extracts were identified by the method of gas chromatography mass-spectrometry [2, 3]. Finally, reforestationafterspruceforestcutting was found to be accompanied by different changes in soil chemical composition. In contrast with soils under undisturbed spruce forest, organic soil horizons under different-aged cuts decreased in organic carbon reserves and production of low-molecular organic compounds, changed in soil acidity. Within the soil series of SP1→SP2→SP3, the highest content of WOCs was identified for undisturbed spruce forest (738 mg kg-1 soil). In soils of coniferous-deciduous forests on SP1 and SP3, WOC content was 294 and 441 mg kg-1 soil, correspondingly. Soils at cuts decreased in concentration of any water-soluble low-molecular SOM components as low-molecular acids, alcohols, and carbohydrates. Structure of low-molecular WOCs in the study podzolic

    The Group of European Municipalities with Nuclear Facilities (GMF) was constituted in 1999. Its basic objectives are to keep and strengthen the relations between municipalities with the aim of consolidating a European network of municipalities with common problems; and to participate in European forums on the future of nuclear energy, contributing and helping in decision making processes. The GMF wants to become a support element to the local authorities of nuclear areas in order to foster their participation in the decision making processes, working continuously in collaboration with other agents of the nuclear sector, especially with the authorities of the European Commission, assuming that its major contribution is the knowledge of the everyday territorial reality, as a fundamental element that should be born in mind in all defined policies, whether on european or national level. It is stated that the debate on the future of nuclear energy represents a new era for the municipalities with nuclear facilities across Europe and that international cooperation will open the way for a better use of nuclear energy in Europe

    Full Text Available This paper aims to identify the manifested connection between the dynamics of the population purchasing power and the dynamic of agroalimentary markets in general as well as by product types on European Union level. Based on the last data supplied by Eurostat 2013, using the specific methods for studying the correlations, we have detected that increases and decreases of the purchasing power generated similar changes on agroalimentary markets level from the point of view of achieved sales in most of the poorer countries of the European Union, but not in those states which got beyond the average gross domestic product per capita of the European Union. This relationship has been noticed only on the agroalimentary markets as a whole (respectively on the amounts spent by the population for purchasing agroalimentary goods, beverages and tobacco, but not on the level of markets of various types of product (“meat and meat products”, “fruit and vegetables”, “dairy produce, eggs and edible oils and fats”, “beverages”, “sugar and chocolate and sugar confectionery”, “tobacco products”.

    Highlights: • This paper studies the effect of an unexpected runway of a control rod in the ESFR. • The power peaked fuel pin within the core was identified. • The increase of the fission power density of the fuel pin has been evaluated. • Radial/axial fission power density of the power peaked fuel pin has been evaluated. - Abstract: The new reactor concepts proposed in the Generation IV International Forum require the development and validation of new components and new materials. Inside the Collaborative Project on the European Sodium Fast Reactor, several accidental scenario have been studied. Nevertheless, none of them coped with mechanical safety assessment of the fuel cladding under accidental conditions. Among the accidental conditions considered, there is the unprotected transient of overpower (UTOP), due to the insertion, at the end of the first fuel cycle, of a positive reactivity into the reactor core as a consequence of the unexpected runaway of one control rod. The goal of the study was the search for a detailed distribution of the fission power, in the radial and axial directions, within the power peaked fuel pin under the above accidental conditions. Results show that after the control rod ejection an increase from 658 W/cm{sup 3} to 894 W/cm{sup 3}, i.e. of some 36%, is expected for the power peaked fuel pin. This information will represent the base to investigate, in a future work, the fuel cladding safety margin.

    The MENA CSP (Middle East and North Africa - Concentrated Solar Power) plan is an ambitious scheme with an appeal to anyone concerned about climate change and convinced by the need for clean, renewable power. But what does it really mean for the average citizen of say Morocco or Tunisia? The World Bank sees potential for significant job and wealth creation in solar energy producing countries. If the CSP market grows rapidly over the next few years, equipment manufacturing will be essential to supply this new sector. This study proposes roadmaps and an action plan to help develop the potential of locally manufactured CSP components in the existing industry and for new market entrants.

    Full Text Available The empirical record on PPP tests for transition economies is far from being so opulent as it is for the developed market economies. This paper attempts to fill this gap by scrutinizing the theory of PPP on a sample of Central and Eastern European economies. The paper has two main advances with respect to previous PPP studies. First, it employs a monthly data base on real exchange rates for a panel of 12 Central and Eastern European economies by testing the theory separately with respect to US dollar and with respect to Euro. Second, we utilise a panel unit root test that involves the estimation of the ADF regression in a SUR framework. Since our study found support for the validity of PPP in some reforming European economies, special attention should be devoted to individual country-specific factors that cause PPP deviations.

    This work consists of assessing the thermal power plants impact on the environment by the global considering of the pollutant SO 2 and NO x emissions. This assessment takes into account the emission comparisons with the admissible values provided by the European norms. The conclusion we might draw is that the SN proposed global criterion application, (S from sulfur, namely the sulfur dioxide and N from nitrogen, namely the nitrogen oxides), the investment expenses for installing the necessary SDN and SDS systems (were SDN stands for denox plant and SDS for desulfurization systems), and the operation expenses are smaller (in case of pit coal they are even smaller) if we apply such criterion. The ecologic analysis model we applied as an estimation for large solid fuels categories (lignite, pit coal) and for the 330 MW existing power units, can also be applied to the actual cases for different fuel qualities or unit unitary power levels

    This paper uses a static computational game theoretic model of a fully opened European electricity market and can take strategic interaction among electricity-producing firms into account. The model is run for a number of scenarios: first, in the baseline under perfect competition, the prices differ due to the presence of various generation technologies and a limited ability to exchange electricity among countries. In addition, when large firms exercise market power, the model runs indicate that prices are the highest in countries where the number of firms is low. Second, dry weather would increase the prices in the hydro-rich Nordic countries followed by the Alpine countries. The price response would be about 20% higher with market power. Third, more transmission capacity would lower the prices in countries with high prices and it also reduces the impact of market power. Hence, more transmission capacity can improve market competitiveness.

    2002-06-01

    A significant source of air pollutants and greenhouse gases in North America is a direct result of the generation of electricity from the combustion of fossil fuels. An attempt at estimating the future emissions of four key pollutants from the electricity generation sector in North America was made by the authors in this paper. They based their estimates on projections of future electricity generation capacity changes. They looked at new power plant projects in North America, as well as the expected changes in emissions as a result of these projects compared to the historical data originating from power plant emissions in the recent past. Both the local context and the national level were examined. Nitrogen oxides, sulfur dioxide, mercury, and carbon dioxide, all arising from the combustion of fossil fuels, were considered in this paper. Ground level ozone, or smog results from nitrogen oxides. Acidic deposition, also called acid rain, is caused in part by both nitrogen oxides and sulfur dioxide, as is fine particles in the atmosphere linked to lung damage and premature death. Fish consumption advisories were issued due to the levels of toxic mercury deposited in lakes and streams. Global climate change is caused in part to the greenhouse gas carbon dioxide. Air quality and climate change will both be impacted by the future evolution of the electricity generation sector in an integrated North American energy market. The authors attempted to provide a baseline of air emissions from that sector in North America for a common reference year, enabling the tracking of changes in emissions patterns in the future. A reference case inventory for the four pollutants was estimated, followed by the development of two boundary cases estimating future emissions in 2007. refs., 22 tabs

    This article discusses how the public utilities in Hannover, Germany, have developed a strategy for the operation of their power generation facilities and power distribution network as independent yet co-operating units. Three models that were examined are described: 'free-sailing', where generation and distribution were kept completely independent, the 'wedding' model, where they were closely tied together and 'Enercity', a mixture of both models. The various rules necessary and the degrees of freedom needed to implement the 'Enercity' model are discussed, as are the advantages it offers to both the power generation and the sales units

  14. Solar Power in the European Context: Conversion Efficiency and the Issue of Carbon

    Directory of Open Access Journals (Sweden)

    Henrique Silva Pacini Costa

    2009-04-01

    Full Text Available The European Union is committed to increasing the use of renewable energies across Europe. One of the ways this is to be done is through the promotion of solar photovoltaics (PV, a method with significant environmental benefits. However, the high costs of electricity generated through PV have constrained the market reach of this option. This paper takes the form of a policy discussion, analyzing the fundamental issues concerning this type of energy, and its place in the European alternative energy market. Furthermore, a scenario is drafted to estimate how efficient solar panels should ideally be to make electricity produced by them cost-competitive with conventional, grid-tied energy sources. The study considers both a conventional scenario and another, with carbon capture costs incorporated into the final electricity prices. It is observed that in order to be competitive with conventional fossil-based electricity, photovoltaic conversion efficiencies should be around 34%. Incorporating carbon costs would further help promote solar PV, making it more price-attractive compared to emission-intensive electricity generation based on fossil fuels. The final part of the paper sheds light on the new developments on European PV, mainly in regards to the 2008 European Commission Climate Change Package, its implications and reactions from the industry.

    This paper discusses a methodology for detailed modelling of electricity generation of large interconnected power systems in a liberalised market. The resulting model, called E-Simulate, respects the technological restrictions and boundary conditions inherent to power generation and simulates the power generation and cross border trade on an hourly basis and on a power plant level. Nevertheless, E-Simulate is sufficiently flexible, transparent and fast. It is a valid, objective and useful tool in the simulation of the impact of power generation topics in the context of liberalised markets and GHG emission reduction. As a comprehensive example of the use and the strength of E-Simulate, we study the effect of a CO 2 tax on power generation and electricity trade in and between eight interconnected European zones: The Netherlands, Belgium/Luxemburg, France, Germany, Spain, Portugal, Switzerland and Italy. A CO 2 tax of 10 Euro /ton CO 2 causes an overall CO 2 emission reduction of about 6%. We notice an overall increase in gas fired generation and a corresponding reduction of coal and lignite fired generation on a trans-national level. In some zones (The Netherlands, Belgium/Luxemburg and Italy), the emissions will rise. In others (France, Germany and Spain), emissions will decrease. This is a result of the CO 2 tax that not only causes a shift towards fuels with lower carbon content but also, and correspondingly, leads to a redistribution of cross border trade

    The status of the European eel population is critical.; the annual recruitment of glass eel to European waters in 2015 is 1.2% of the 1960-1979 level in the 'North Sea' area, and 8.4% in the rest of Europe (ICES 2015) . There are a number of anthropogenic impacts potentially affecting eel population including commercial exploitation, habitat loss, dam and weir construction, hydropower, pumping stations and surface water abstractions. Furthermore, the first eel stages and larval migration and marine survival are heavily influenced by oceanic and climatic factors since the species breeds in the Sargasso Sea and migrates to the continental shelf of the Atlantic coast of Europe and North Africa. Therefore, the study of the relations between recruitment and oceanic conditions may allow to study the potential effect of climatic change on the future eel recruitment and therefore stock. In the present study, the relation between glass eel recruitment and oceanic and climatic factors has been studied. Historic glass eel catches data beginning in the 50s from two Mediterranean and two Atlantic estuaries have been used as a proxy of recruitment. The relation of catches with the main oceanographic and climatic factors identified in the literature was established using an ocean reanalysis, the Simple Ocean Data Assimilation (SODA) and determined which variables are significantly related to the number of catches. The analysis shows significant relationships between catches and oceanic (Surface Downward Stress, Sea Water Temperature and Sea Water Velocity) and atmospheric (NAO Index, AMO Index) variables. Subsequently, we applied the results of three climate models (GFDL-ESM2M, CanESM2 and CNRM-CM5), associated with the Coupled Model Intercomparison Project Phase 5 (CMIP5) under two simulations of climate change (RCP4.5 and RCP8.5), both associated with the 5th Assessment Report of the IPCC, for possible future influences on the eel. This research was funded by the Spanish

    Wind energy resource is subject to changes in climate. To investigate the impacts of climate change on future European wind power generation potential, we analyze a multi-model ensemble of the most recent EURO-CORDEX regional climate simulations at the 12 km grid resolution. We developed a mid-century wind power plant scenario to focus the impact assessment on relevant locations for future wind power industry. We found that, under two greenhouse gas concentration scenarios, changes in the annual energy yield of the future European wind farms fleet as a whole will remain within ±5% across the 21st century. At country to local scales, wind farm yields will undergo changes up to 15% in magnitude, according to the large majority of models, but smaller than 5% in magnitude for most regions and models. The southern fleets such as the Iberian and Italian fleets are likely to be the most affected. With regard to variability, changes are essentially small or poorly significant from subdaily to interannual time scales. (letter)

    Decarbonizing electricity production is central to reducing greenhouse gas emissions. Exploiting intermittent renewable energy resources demands power system planning models with high temporal and spatial resolution. We use a mixed-integer linear programming model – SWITCH – to analyze least-cost generation, storage, and transmission capacity expansion for western North America under various policy and cost scenarios. Current renewable portfolio standards are shown to be insufficient to meet emission reduction targets by 2030 without new policy. With stronger carbon policy consistent with a 450 ppm climate stabilization scenario, power sector emissions can be reduced to 54% of 1990 levels by 2030 using different portfolios of existing generation technologies. Under a range of resource cost scenarios, most coal power plants would be replaced by solar, wind, gas, and/or nuclear generation, with intermittent renewable sources providing at least 17% and as much as 29% of total power by 2030. The carbon price to induce these deep carbon emission reductions is high, but, assuming carbon price revenues are reinvested in the power sector, the cost of power is found to increase by at most 20% relative to business-as-usual projections. - Highlights: ► Intermittent generation necessitates high-resolution electric power system models. ► We apply the SWITCH planning model to the western North American grid. ► We explore carbon policy and resource cost scenarios through 2030. ► As the carbon price rises, coal generation is replaced with solar, wind, gas and/or nuclear generation ► A 450 ppm climate stabilization target can be met at a 20% or lower cost increase.

  2. Modeling dust emission response to North Atlantic millennial-scale climate variations from the perspective of East European MIS 3 loess deposits

    Full Text Available European loess sequences of the Marine Isotope Stage 3 (~60–25 kyr BP show periods of strong dust accumulation alternating with episodes of reduced sedimentation, favoring soil development. In the western part of the loess belt centered around 50° N, these variations appear to have been related to the North Atlantic rapid climate changes: the Dansgaard–Oeschger (DO and Heinrich (H events. It has been recently suggested that the North Atlantic climate signal can be detected further east, in loess deposits from Stayky (50°05.65' N, 30°53.92' E, Ukraine. Here we use climate and dust emission modeling to investigate this data interpretation. We focus on the areas north and northeast of the Carpathians, where loess deposits can be found, and the corresponding main dust sources must have been located as well. The simulations were performed with the LMDZ atmospheric general circulation model and the ORCHIDEE land surface model. They represent a reference "Greenland stadial" state and two perturbations, seen as sensitivity tests with respect to changes in the North Atlantic surface conditions between 30° and 63° N: a "Greenland interstadial" and an "H event". The main source for the loess deposits in the studied area is identified as a dust deflation band, with two very active spots located west-northwest from our reference site. Emissions only occur between February and June. Differences from one deflation spot to another, and from one climate state to another, are explained by analyzing the relevant meteorological and surface variables. Over most of the source region, the annual emission fluxes in the "interstadial" experiment are 30 to 50% lower than the "stadial" values; they would only be about 20% lower if the inhibition of dust uplift by the vegetation were not taken into account. Assuming that lower emissions result in reduced dust deposition leads us to the conclusion that the loess–paleosol stratigraphic succession in the Stayky

    The contribution outlines legal problems from the view of national and European law. It presents alternative funding models and investigates their legal applicability. For example, funds may be established with obligatory contributions by nuclear power plant operators. A model of this type was proposed by the EU Commission. The authors discuss whether the EU Commission has the right at all to make this proposal, and what legal problems may arise in Germany, e.g. the right of property of public utilities. Other funding models are presented and investigated as well. (orig.)

    Understanding the status of contaminants in the marine environment is a requirement of European Union Directives and the Regional Seas Conventions, so that measures to reduce pollution can be identified and their efficacy assessed. The international ICON workshop (Hylland et al., in this issue) was developed in order to test an integrated approach to assessing both contaminant concentrations and their effects. This paper describes and assesses the concentrations of trace metals, polycyclic aromatic hydrocarbons, and polychlorinated biphenyls in sediments, mussels, and fish collected from estuarine, coastal and offshore waters from Iceland to the Mediterranean Sea. For organic contaminants, concentrations progressively increased from Iceland, to the offshore North Sea, to the coastal seas, and were highest in estuaries. Metals had a more complex distribution, reflecting local anthropogenic inputs, natural sources and hydrological conditions. Use of internationally recognised assessment criteria indicated that at no site were concentrations of all contaminants at background and that concentrations of some contaminants were of significant concern in all areas, except the central North Sea.

    Life satisfaction (LS) is an indicator which is widely used for assessing the perception of a child's feeling about his life. LS is assessed in Health Behaviour in School-aged Children via the Cantril ladder with 10 steps indicating the worst and best possible life. This range of values (0-10) was dichotomized into 'low' (0-5) vs. 'high' (6-10). Countries, age groups and genders were compared based on the odds ratio (OR) of declaring a higher LS in 2010 with respect to 2002. Analyzing the difference between 2002 and 2010, six countries from Western Europe show decreasing LS: Austria, Canada, Switzerland, Denmark, Finland and Greenland. In contrast, a group of Eastern European Countries, that is, Estonia, Croatia, Lithuania, Latvia, Russia and Ukraine, show a significant increase in LS. Data on gender and age differences confirm the lower rating of LS in girls and a decreasing rating with age. The LS scale appears to be a tool capable of discriminating the level of wellbeing of adolescent population among countries. © The Author 2015.

    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

    Creating a European electrical network is an idea originating from the inter-war years and that was to be realized only in 1995. By replacing the history of this idea within its historic dimension, this article breaks with the determinist visions. The actor's play and more particularly the international institutions, can explain that the European dimension, even though continually asserted, has only been designed as the growth of the regional networks. Additionally, in the context of cold war, the projects that associate the East to the West had to overcome several obstacles. Parties were brought together many times, but only the fall of the Iron Curtain has enabled a true interconnection between the two halves of Europe

    By tracing the development of theories of comedy within Western philosophy, this thesis claims that anti-comic prejudices prevented comedy from being recognized as a serious genre. Comedy's inferior status for over two thousand years is shown to correspond to an ethical model that distinguishes the real from the Ideal and affirms a Neo-Platonic vision of existence. Through numerous examples taken from a particular phenomenon of post-war European theatre comprising five different playwrights, ...

    This study explores and assesses challenges for the European permitting and planning system with regard to grid development in the North Sea. The following question is discussed: What planning and permitting challenges can influence the realization of an offshore grid in the North Sea? This is answered by referring to the political context of the North Sea and the development of an offshore grid therein. We present the main features of the proposed regulation by the European Commission (COM(2011)658) that will, if it is adapted, impact current grid permitting procedures. Further, key supranational planning tools for offshore grid development are accounted for and the proposed EU measures are discussed with reference to relevant studies on planning and permitting procedures of realizing electricity grids. Finally, the report provides the general findings and conclusions. (Author)

    Capacity development (CD) in food and nutrition is much more than formal training and includes human resource development, and organisational, institutional and legal framework development with the aim of enhancing nutrition-relevant knowledge and skills to support infrastructural development. The goal of the European Food Information Resource (EuroFIR) Network of Excellence has been to develop and integrate food composition data throughout Europe. EuroFIR joined forces in CD with the United Nations (UN) University and UN System Standing Committee on Nutrition, the Network for Capacity Development in Nutrition in Central and Eastern Europe, the Central and Eastern European Countries Food Data Systems network and with the Middle East and North African Capacity Building Initiative. The aim of this paper is to discuss an inventory of the status of food composition databases (FCDBs) and the training needs of compilers in non-EuroFIR countries in Central and Eastern Europe (CEE) and in the Middle East and North Africa (MENA), and to present the CD achieved through EuroFIR and other network collaborations. Two online questionnaires were created addressing the FCDB status and specific training needs in countries of the targeted regions. Data were collected during 2006-2008 and then analysed. Subsequently, CD activities were organised. Contacts were established in 19 CEE and 7 MENA countries, of which several had national food composition tables, but no electronic versions. Education, training, workshops, networking and the sharing of experiences were uniformly requested. Subsequently, CD activities in EuroFIR were organised focussing on food composition courses, exchange visits, workshops and individual training for PhD students, junior scientists and other staff categories, as well as conferences linked to food composition research and food information. To facilitate CD activities, EuroFIR has signed a Memorandum of Understanding with the Czech Republic, Hungary

    2010-01-01

    Risk-informed in-service inspection (RI-ISI) methods aim at enhancing ISI effectiveness by taking into account the risk importance of possible inspection sites. These methods are widely applied in US, but in Europe the situation is different, as there are many regulatory environments implying a variety of ISI codes and standards and national guidelines. The objective of the European Network for Inspection Qualification, ENIQ, is to co-ordinate and to manage at European level expertise and resources for the qualification of non-destructive inspection techniques and procedures primarily for the in-service inspection of nuclear components. ENIQ has established a Task Group on Risk (TGR) to work towards developing best practice for RI-ISI methodologies. TGR has published a European framework document for risk-informed in-service inspection, and the group has been working at producing more detailed recommended practices and discussion documents on several RI-ISI related issues. In addition, TGR has been active in initiating international projects, such as the JRC-OECD/NEA coordinated RI-ISI benchmark exercise (RISMET). This paper describes the activities and publications of TGR to date, and summarises the contents and main results of the RISMET RI-ISI benchmark exercise. (orig.)

  15. Making full use of wind power potential in North America -- possibilities

    Energy Technology Data Exchange (ETDEWEB)

    Guillaud, Christian

    2010-09-15

    The anticipated increase in electrical load in North America up to the year 2050 will be at least 50%. Wind potential in North America is enormous, well in excess of the expected requirements. However, the amount of wind capacity, which can be directly connected to a grid is limited to 20% of the installed capacity because of technical constraints. Technologies to enable full wind potential to be harnessed still need to be developed; they will consist in storing wind energy in hydroelectric reservoirs or generating hydrogen. However, the resulting cost of electricity will be somewhat higher than present.

  16. The impact of European balancing rules on wind power economics and on short-term bidding strategies

    International Nuclear Information System (INIS)

    Chaves-Ávila, J.P.; Hakvoort, R.A.; Ramos, A.

    2014-01-01

    Wind power represents a significant percentage of the European generation mix and this will increase to fulfill the renewable energy targets. Different balancing rules are applied to wind power among the countries; for instance, to what extent wind power producers (WPPs) are responsible for the energy imbalances and how those imbalances are penalized. This paper discusses those different rules and evaluates their effects on WPP bidding strategies. To do so, a quantitative analysis is presented for an offshore wind farm, considering the differences in the balancing rules and prices of Belgium, Denmark, Germany and the Netherlands. The quantitative approach consists of a stochastic optimization model that maximizes the profits of a WPP by trading in different markets (day-ahead and intraday) and computes the final energy delivered. The model considers uncertainties of most important parameters such as wind energy forecasts and prices at different time frames. The results show that the imbalance pricing design and the allocation of balance responsibility significantly affect WPP’ revenues. Additionally, WPPs deviate differently from the expected energy depending on the balancing rules, which can impact the system. Furthermore, these balancing rules should be considered with other market regulations, such as the design of support schemes. - Highlights: • European countries apply different imbalance pricing rules. • The allocation of balance responsibility to wind power varies between the countries. • A stochastic optimization model is used to compare the effect of balancing rules. • Balancing rules have an important impact on wind generators bidding strategies. • Balancing rules have also an effect on the system imbalances

  17. Pu isotopes in the western North Pacific Ocean before the accident at Fukushima Dai-ichi Nuclear Power Station

    Science.gov (United States)

    Yamada, M.; Zheng, J.; Aono, T.

    2011-12-01

    Anthropogenic radionuclides such as Pu-239 (half-life: 24100 yr), Pu-240 (half-life: 6560 yr) and Pu-241 (half-life: 14.325 yr) mainly have been released into the environment as the result of atmospheric nuclear weapons testing. In the North Pacific Ocean, two distinct sources of Pu isotopes can be identified; i.e., the global stratospheric fallout and close-in tropospheric fallout from nuclear weapons testing at the Pacific Proving Grounds in the Marshall Islands. The atom ratio of Pu-240/Pu-239 is a powerful fingerprint to identify the sources of Pu in the ocean. The Pu-240/Pu-239 atom ratios in seawater and marine sediment samples collected in the western North Pacific before the accident at Fukushima Dai-ichi Nuclear Power Station will provide useful background data for understanding the process controlling Pu transport and for distinguishing future Pu sources. The atom ratios of Pu-240/Pu-239 in water columns from the Yamato and Tsushima Basins in the Japan Sea were significantly higher than the mean global fallout ratio of 0.18; however, there were no temporal variation of atom ratios during the period from 1984 to 1993 in the Japan Sea. The total Pu-239+240 inventories in the whole water columns were approximately doubled during the period from 1984 to 1993 in the two basins. The atom ratio of Pu-240/Pu-239 in surface water from Sagami Bay, western North Pacific Ocean, was 0.224 and showed no notable variation from the surface to the bottom with the mean atom ratio being 0.234. The atom ratios for the Pacific coast, near the Rokkasho nuclear fuel reprocessing plant, were approximately the same as the 0.224 ratio obtained from Sagami Bay, western North Pacific margin. The atom ratios in the surficial sediments from Sagami Bay ranged from 0.229 to 0.247. The mean atom ratio in the sediment columns in the East China Sea ranged from 0.248 for the Changjiang estuary to 0.268 for the shelf edge. The observed atom ratios were significantly higher than the mean

    Highlights: •Wind speed spatial resolution highly influences calculated wind power peaks and ramps. •Reduction of wind power generation uncertainties using statistical downscaling. •Publicly available dataset of wind power generation hourly time series at NUTS2. -- Abstract: The growing share of electricity production from solar and mainly wind resources constantly increases the stochastic nature of the power system. Modelling the high share of renewable energy sources – and in particular wind power – crucially depends on the adequate representation of the intermittency and characteristics of the wind resource which is related to the accuracy of the approach in converting wind speed data into power values. One of the main factors contributing to the uncertainty in these conversion methods is the selection of the spatial resolution. Although numerical weather prediction models can simulate wind speeds at higher spatial resolution (up to 1 × 1 km) than a reanalysis (generally, ranging from about 25 km to 70 km), they require high computational resources and massive storage systems: therefore, the most common alternative is to use the reanalysis data. However, local wind features could not be captured by the use of a reanalysis technique and could be translated into misinterpretations of the wind power peaks, ramping capacities, the behaviour of power prices, as well as bidding strategies for the electricity market. This study contributes to the understanding what is captured by different wind speeds spatial resolution datasets, the importance of using high resolution data for the conversion into power and the implications in power system analyses. It is proposed a methodology to increase the spatial resolution from a reanalysis. This study presents an open access renewable generation time series dataset for the EU-28 and neighbouring countries at hourly intervals and at different geographical aggregation levels (country, bidding zone and administrative

  19. West Nile Virus: High Transmission Rate in North-Western European Mosquitoes Indicates Its Epidemic Potential and Warrants Increased Surveillance.

    Directory of Open Access Journals (Sweden)

    Jelke J Fros

    Full Text Available West Nile virus (WNV is a highly pathogenic flavivirus transmitted by Culex spp. mosquitoes. In North America (NA, lineage 1 WNV caused the largest outbreak of neuroinvasive disease to date, while a novel pathogenic lineage 2 strain circulates in southern Europe. To estimate WNV lineage 2 epidemic potential it is paramount to know if mosquitoes from currently WNV-free areas can support further spread of this epidemic.We assessed WNV vector competence of Culex pipiens mosquitoes originating from north-western Europe (NWE in direct comparison with those from NA. We exposed mosquitoes to infectious blood meals of lineage 1 or 2 WNV and determined the infection and transmission rates. We explored reasons for vector competence differences by comparing intrathoracic injection versus blood meal infection, and we investigated the influence of temperature. We found that NWE mosquitoes are highly competent for both WNV lineages, with transmission rates up to 25%. Compared to NA mosquitoes, transmission rates for lineage 2 WNV were significantly elevated in NWE mosquitoes due to better virus dissemination from the midgut and a shorter extrinsic incubation time. WNV infection rates further increased with temperature increase.Our study provides experimental evidence to indicate markedly different risk levels between both continents for lineage 2 WNV transmission and suggests a degree of genotype-genotype specificity in the interaction between virus and vector. Our experiments with varying temperatures explain the current localized WNV activity in southern Europe, yet imply further epidemic spread throughout NWE during periods with favourable climatic conditions. This emphasizes the need for intensified surveillance of virus activity in current WNV disease-free regions and warrants increased awareness in clinics throughout Europe.

Our research examined whether there was a difference in the acceptance of nuclear energy across 27 European countries in 2009, before the Fukushima accident. In particular, we analyzed how each factor at the individual and contextual level influences the acceptance. To answer this question, we set up the acceptance of nuclear energy as a dependent variable, and 5 perception variables at the individual level and 11 structural ones at the contextual level as independent variables. We executed multilevel modeling by using a Eurobarometer survey, which covered 27 European countries. The analysis results showed that at the individual level, the perceived benefit explained the largest variance of the acceptance, followed by perceived risk and trust. At the contextual level, the share of the energy supply by nuclear power, environmentalism and ideology influenced the acceptance of nuclear energy. This study shows that individuals’ acceptance of nuclear energy is based on individual beliefs and perceptions, but it is also influenced by the institutional and socio-cultural context which each country faces.

  1. Reduction of electricity use in Swedish industry and its impact on national power supply and European CO2 emissions

    Decreased energy use is crucial for achieving sustainable energy solutions. This paper presents current and possible future electricity use in Swedish industry. Non-heavy lines of business (e.g. food, vehicles) that use one-third of the electricity in Swedish industry are analysed in detail. Most electricity is used in the support processes pumping and ventilation, and manufacturing by decomposition. Energy conservation can take place through e.g. more efficient light fittings and switching off ventilation during night and weekends. By energy-carrier switching, electricity used for heat production is replaced by e.g. fuel. Taking technically possible demand-side measures in the whole lines of business, according to energy audits in a set of factories, means a 35% demand reduction. A systems analysis of power production, trade, demand and conservation was made using the MODEST energy system optimisation model, which uses linear programming and considers the time-dependent impact on demand for days, weeks and seasons. Electricity that is replaced by district heating from a combined heat and power (CHP) plant has a dual impact on the electricity system through reduced demand and increased electricity generation. Reduced electricity consumption and enhanced cogeneration in Sweden enables increased electricity export, which displaces coal-fired condensing plants in the European electricity market and helps to reduce European CO 2 emissions. Within the European emission trading system, those electricity conservation measures should be taken that are more cost-efficient than other ways of reducing CO 2 emissions. The demand-side measures turn net electricity imports into net export and reduce annual operation costs and net CO 2 emissions due to covering Swedish electricity demand by 200 million euros and 6 Mtonne, respectively. With estimated electricity conservation in the whole of Swedish industry, net electricity exports would be larger and net CO 2 emissions would be

    Estimated radiation dose is important for assessing and communicating the risks and benefits of pediatric nuclear medicine studies. Radiation dose depends on the radiopharmaceutical, the administered activity, and patient factors such as age and size. Most radiation dose estimates for pediatric nuclear medicine have not been based on administered activities of radiopharmaceuticals recommended by established practice guidelines. The dosage card of the European Association of Nuclear Medicine (EANM) and the North American consensus guidelines each provide recommendations of administered activities of radiopharmaceuticals in children, but there are substantial differences between these two guidelines. For 12 commonly performed pediatric nuclear medicine studies, two established pediatric radiopharmaceutical administration guidelines were used to calculate updated radiation dose estimates and to compare the radiation exposure resulting from the recommendations of each of the guidelines. Estimated radiation doses were calculated for 12 common procedures in pediatric nuclear medicine using administered activities recommended by the dosage card of the EANM (version 1.5.2008) and the 2010 North American consensus guidelines for radiopharmaceutical administered activities in pediatrics. Based on standard models and nominal age-based weights, radiation dose was estimated for typical patients at ages 1, 5, 10 and 15 years and adult. The resulting effective doses were compared, with differences greater than 20% considered significant. Following either the EANM dosage card or the 2010 North American guidelines, the highest effective doses occur with radiopharmaceuticals labeled with fluorine-18 and iodine-123. In 24% of cases, following the North American consensus guidelines would result in a substantially higher radiation dose. The guidelines of the EANM dosage card would lead to a substantially higher radiation dose in 39% of all cases, and in 62% of cases in which patients

    Local to regional climate anomalies are to a large extent determined by the state of the atmospheric circulation. The knowledge of large-scale sea level pressure (SLP) variations in former times is therefore crucial when addressing past climate changes across Europe and the Mediterranean. However, currently available SLP reconstructions lack data from the ocean, particularly in the pre-1850 period. Here we present a new statistically-derived 5 x 5 resolved gridded seasonal SLP dataset covering the eastern North Atlantic, Europe and the Mediterranean area (40 W-50 E; 20 N-70 N) back to 1750 using terrestrial instrumental pressure series and marine wind information from ship logbooks. For the period 1750-1850, the new SLP reconstruction provides a more accurate representation of the strength of the winter westerlies as well as the location and variability of the Azores High than currently available multiproxy pressure field reconstructions. These findings strongly support the potential of ship logbooks as an important source to determine past circulation variations especially for the pre-1850 period. This new dataset can be further used for dynamical studies relating large-scale atmospheric circulation to temperature and precipitation variability over the Mediterranean and Eurasia, for the comparison with outputs from GCMs as well as for detection and attribution studies.

    Full Text Available Dorena Genetic Resource Center (DGRC has used artificial inoculation trials to evaluate progenies of thousands of Pinus monticola and P. lambertiana selections from Oregon and Washington for resistance to white pine blister rust caused by Cronartium ribicola. In addition, early results are now available for P. albicaulis and P. strobiformis. DGRC has also recently evaluated seed orchard progenies of P. strobus, as well as bulked seedlots from P. armandii and P. peuce. The majority of P. monticola, P. lambertiana, P. albicaulis, and P. strobus progenies are very susceptible to blister rust. However, resistance exists in all these species. P. strobiformis showed relatively high levels of resistance for the eight progenies tested. Resistance in P. armandii was mainly reflected in the very low percentage of cankered seedlings; for P. peuce, the high percentage of cankered seedlings alive three years after inoculation was notable. R-genes are present in some of the North American five-needle pine species, but partial resistance traits (e.g. bark reaction will play a major role in breeding activities for P. monticola and P. lambertiana and will likely be the key to developing durable resistance.

  8. What can gene flow and recruitment dynamics tell us about connectivity between European hake stocks in the Eastern North Atlantic?

    2011-04-01

    Systematic genetic analyses of fish populations allow the testing of temporal stability in their genetic structures and better understanding their pattern of connectivity. In this study the pattern of gene flow between the two Atlantic stocks of the European hake has been examined for the period 2000-2002. Present analyses indicate that a large genetic homogeneity existed among all Atlantic populations in that period, and that a systematic grouping occurred between Porcupine Bank samples and Cantabric ones. This scenario is congruent with an inter-annual gene flow from central grounds of the northern stock (Porcupine and Great Sole) to Iberian grounds inhabited by the southern stock. Additionally, estimated migration figures were in agreement with the good recruitments observed in the southern stock after 2003 despite the spawning biomass was at its historical minimum. Altogether these results highlight the central role of Porcupine bank and Great Sole in making sustainable both stocks and advocate the integrative management of this hake fishery by means of a multidisciplinary assessment.

  9. Norway as a Battery for the Future European Power System—Impacts on the Hydropower System

    2017-12-01

    Full Text Available Future power production in Europe is expected to include large shares of variable wind and solar power production. Norway, with approximately half of the hydropower reservoir capacity in Europe, can contribute to balance the variability. The aim of this paper is to assess how such a role may impact the Norwegian hydropower system in terms of production pattern of the plants, changes in reservoir level and water values. The study uses a stochastic optimization and simulation model and analyses an eHighway2050 scenario combined with increases in the hydropower production capacities in Norway. The capacity increases from ca. 31 GW in the present system to 42 and 50 GW respectively. The study uses 75 years with stochastic wind, solar radiation, temperature and inflow data. The results show that the hydropower system is able to partly balance the variable production and significantly reduce the power prices for the analyzed case. The paper shows that some of the power plants utilize their increased capacity, while other plants do not due to hydrological constraints and model limitations. The paper discusses how the modelling can be further improved in order to quantify more of the potential impacts on the future power system.

    We describe a measurement of the angular power spectrum of anisotropies in the Cosmic Microwave Background (CMB) from 0.3 degrees to ~10 degrees from the North American test flight of the BOOMERANG experiment. BOOMERANG is a balloon-borne telescope with a bolometric receiver designed to map CMB anisotropies on a Long Duration Balloon flight. During a 6-hour test flight of a prototype system in 1997, we mapped > 200 square degrees at high galactic latitudes in two bands centered at 90 and 150 GHz with a resolution of 26 and 16.6 arcmin FWHM respectively. Analysis of the maps gives a power spectrum with a peak at angular scales of ~1 degree with an amplitude ~70 uK.

    Large power plants for power generation from fossil fuels are constantly being optimised in order to improve their efficiency. One element of the overall considerations is once-through cooling with brackish or seawater on sites near the sea. In addition to the higher overall efficiency, such sites - thanks to their connection to ocean shipping - also offer infrastructural advantages regarding fuel supply and residual material disposal compared to inland sites. Because the cooling water intake and discharge structures have to be built anyway, they lend themselves to also producing the process and demineralised water from the brackish or seawater. In this case, the use of fresh or drinking water as resources can be minimised. In the following report, we present a pilot study using ultrafiltration and reverse osmosis on a North Sea site with raw water intake from a seaport basin. (orig.)

    The 1968 salvage excavations at Pukearuhe (N99/49), north Taranaki, are reported. Pukearuhe was for long a Ngati Tama fortification; in the period 1865-1885 it was occupied by european forces, firstly, imperial troops and Taranaki military settlers, later, armed constabulary. Ngati Tama and european occupation was based on the powerful strategic situation of Pukearuhe at the northern gateway into Taranaki. Excavations revealed evidence of the Maori and European occupation. Radiocarbon dates were obtained for Maori occupation. European material adds to the knowledge of sites relating to the period of military conflict in Taranaki which extended from 1860 to the early 1880s

    In the current context of falling prices, nuclear power proves competitive and this will only progress in the coming years. For the future, nuclear power must draw on two assets, namely environment and economy. It offers a reliable and stable procurement policy, with both security and energy independence. As a matter of fact, only nuclear power may guarantee stable prices over the long term. Other energy sources are branded by a high volatility in prices. And this volatility has a price in itself: customers are obliged to hedge their risk exposure with financial tools. It remains to be assessed what will be the share of these risk-coverage tools in the various energy offers, and what amounts the customers will be ready to pay for their risk-exposure. All the above being economical scenarios in a newly emerging and fluctuating market, where forecasts and market trending are still relatively doubtful. (author)

  15. Productivity, facies and stable-isotope records of OAE2 (Cenomanian - Turonian) in the NW European epicontinental sea: from the English Chalk to North Sea black shales

    The Late Cretaceous (100.5 - 66.0 Ma) provides perhaps the best example of how the Earth System may function under long-term extreme greenhouse conditions. Rapidly rising global temperatures indicate that we are heading 'back to the Cretaceous' within a few hundred years, so a better understanding of this time interval is essential. The beginning of the Late Cretaceous was characterized by a period of rapidly rising eustatic sea level, the Cenomanian transgression, which flooded continental margins and established large areas of new epicontinental sea that accumulated thick sequences of pelagic and hemipelagic carbonate (chalk). Highest global temperatures were reached during the early part of the Turonian Stage (93.9 - 89.8 Ma). This period of dramatic palaeoenvironmental change was accompanied by one the largest perturbations of the global carbon cycle in the Mesozoic: Oceanic Anoxic Event 2 (OAE2), which was characterized by a 500 kyr episode of oceanic anoxia, widespread black shale deposition, biotic turnover, and a large global positive carbon stable-isotope excursion (2 - 6 ‰ ∂13C) recorded in marine carbonates and both marine and terrestrial organic matter. The Cenomanian-Turonian boundary interval exposed at Eastbourne, southern England, has become established as a European reference section for OAE2. Here, and elsewhere in Europe, the base of the ∂13C excursion is coincident with a marked facies change from rhythmically bedded grey chalks and marls, to a >8 m thick package of dark greenish-grey marl - the Plenus Marl. The termination of OAE2 occurs 6 m above, in a package of pale-yellow-weathering nodular chalks with prominent marl seams. Sediments are organic lean (10 wt%. The onshore equivalent in eastern England (the Black Band) is similarly organic-rich, as are comparable sections in northern Germany (e.g. Wunstorf), indicating likely fully anoxic episodes within some NW European basins. The exact stratigraphic equivalence between the onshore

    One of the founding treaties (the Euratom Treaty) of the European Community, to which the UK acceeded in 1973, foresaw an important role for nuclear energy in helping to develop economic prosperity and in facilitating collaboration with other countries. Nuclear energy already provides some 10% of all Community electricity but neither this contribution, nor that now forecast, is as great as was foreseen a few years ago. The causes of this shortfall are identified: they cover socio-economic, technical and political problems, and are exhibited, in varying degrees, in all nine Member States of the Community. It is suggested that, although some aspects of the matter are the inescapable responsibility of individual Member States, there are many features where a common Community position can be advantageous to all.

    Extranodal NK/T cell lymphoma, nasal type (ENKTL-NT) is an aggressive extranodal non-Hodgkin lymphoma most commonly occurring in East Asia and Latin America but with increasing incidence in the United States. Data on epidemiology, disease presentation, and outcome for European and North American ("Western") cases are very limited. We review published landmark clinical studies on ENKTL-NT in the West and report in detail recent data, including our institutional experience. We highlight key observations in its epidemiology, natural history, and trends in clinical management. In the USA, ENKTL-NT is more common among Asian Pacific Islanders (API) and Hispanics compared to non-Hispanic whites. Published studies indicate less heterogeneity in clinical presentation in Western ENKTL-NT compared to Asian patients. While there is variation in age at diagnosis, presence of antecedent lymphoproliferative disorders, and outcomes among racial/ethnic groups, the universal association of ENKTL-NT with EBV and the poor response of this neoplasm to anthracycline-based therapy is consistent across all geographic areas. Data on epidemiology, disease presentation, and clinical outcomes in mature T cell and NK cell (T/NK cell) neoplasms, including ENKTL-NT, in Europe and North America are very limited. As the classification and diagnostic characterization of the currently recognized T/NK cell lymphoma disease entities continue to evolve, gaps and inconsistencies in data reporting across different studies are being recognized. Despite these limitations, several studies from the USA suggest that the incidence of ENKTL-NT is higher in Asian Pacific Islanders (API) and non-white Hispanics and that outcomes may be worse in non-whites. However, the universal association of ENKTL-NT with Epstein-Barr virus (EBV) across all ethnic groups suggests a common pathogenesis. Given the overlap between the entities included in the category of T/NK cell neoplasms, there is a need to further define

  18. Exclusion and Inclusion of Nonwhite Ethnic Minority Groups in 72 North American and European Cardiovascular Cohort Studies.

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available BACKGROUND: Cohort studies are recommended for understanding ethnic disparities in cardiovascular disease. Our objective was to review the process for identifying, including, and excluding ethnic minority populations in published cardiovascular cohort studies in Europe and North America. METHODS AND FINDINGS: We found the literature using Medline (1966-2005, Embase (1980-2001, Cinahl, Web of Science, and citations from references; consultations with colleagues; Internet searches; and RB's personal files. A total of 72 studies were included, 39 starting after 1975. Decision-making on inclusion and exclusion of racial/ethnic groups, the conceptual basis of race/ethnicity, and methods of classification of racial/ethnic groups were rarely explicit. Few publications provided details on the racial/ethnic composition of the study setting or sample, and 39 gave no description. Several studies were located in small towns or in occupational settings, where ethnic minority populations are underrepresented. Studies on general populations usually had too few participants for analysis by race/ethnicity. Eight studies were explicitly on Caucasians/whites, and two excluded ethnic minority groups from the whole or part of the study on the basis of language or birthplace criteria. Ten studies were designed to compare white and nonwhite populations, while five studies focused on one nonwhite racial/ethnic group; all 15 of these were performed in the US. CONCLUSIONS: There is a shortage of information from cardiovascular cohort studies on racial/ethnic minority populations, although this has recently changed in the US. There is, particularly in Europe, an inequity resulting from a lack of research data in nonwhite populations. Urgent action is now required in Europe to address this disparity.

    Several studies have demonstrated that perioperative hemodynamic optimization has the ability to improve postoperative outcome in high-risk surgical patients. All of these studies aimed at optimizing cardiac output and/or oxygen delivery in the perioperative period. We conducted a survey with the American Society of Anesthesiologists (ASA) and the European Society of Anaesthesiology (ESA) to assess current hemodynamic management practices in patients undergoing high-risk surgery in Europe and in the United States. A survey including 33 specific questions was emailed to 2,500 randomly selected active members of the ASA and to active ESA members. Overall, 368 questionnaires were completed, 57.1% from ASA and 42.9% from ESA members. Cardiac output is monitored by only 34% of ASA and ESA respondents (P = 0.49) while central venous pressure is monitored by 73% of ASA respondents and 84% of ESA respondents (P < 0.01). Specifically, the pulmonary artery catheter is being used much more frequently in the US than in Europe in the setup of high-risk surgery (85.1% vs. 55.3% respectively, P < 0.001). Clinical experience, blood pressure, central venous pressure, and urine output are the most widely indicators of volume expansion. Finally, 86.5% of ASA respondents and 98.1% of ESA respondents believe that their current hemodynamic management could be improved. In conclusion, these results point to a considerable gap between the accumulating evidence about the benefits of perioperative hemodynamic optimization and the available technologies that may facilitate its clinical implementation, and clinical practices in both Europe and the United States.

    Classical approaches to the calculation of the photovoltaic (PV) power generated in a region from meteorological data require the knowledge of the detailed characteristics of the plants, which are most often not publicly available. An approach is proposed with the objective to obtain the best possible assessment of power generated in any region without having to collect detailed information on PV plants. The proposed approach is based on a model of PV plant coupled with a statistical distribution of the prominent characteristics of the configuration of the plant and is tested over Europe. The generated PV power is first calculated for each of the plant configurations frequently found in a given region and then aggregated taking into account the probability of occurrence of each configuration. A statistical distribution has been constructed from detailed information obtained for several thousands of PV plants representing approximately 2 % of the total number of PV plants in Germany and was then adapted to other European countries by taking into account changes in the optimal PV tilt angle as a function of the latitude and meteorological conditions. The model has been run with bias-adjusted ERA-interim data as meteorological inputs. The results have been compared to estimates of the total PV power generated in two countries: France and Germany, as provided by the corresponding transmission system operators. Relative RMSE of 4.2 and 3.8 % and relative biases of -2.4 and 0.1 % were found with three-hourly data for France and Germany. A validation against estimates of the country-wide PV-power generation provided by the ENTSO-E for 16 European countries has also been conducted. This evaluation is made difficult by the uncertainty on the installed capacity corresponding to the ENTSO-E data but it nevertheless allows demonstrating that the model output and TSO data are highly correlated in most countries. Given the simplicity of the proposed approach these results are

    Renewable sources of electricity production are strongly increasing in many parts of the world. The production costs are going down quickly, thus accelerating the deployment of new solar and wind electricity generation. In the long-term, these variable sources of electricity could represent a high share of the power system. However, long-term foresight energy models have difficulties describing precisely the integration challenges of Variable Renewable Energy Sources (VRES) such as wind or solar. They just do not represent the short-term technical constraints of the power sector. The objective of this paper is to show a new approach of the representation of the challenges of variability in the long-term foresight energy model POLES (Prospective Outlook on Long-term Energy Systems). We develop a short-term optimization model for the power sector operation, EUCAD (European Unit Commitment and Dispatch) and we couple it to POLES year after year. The direct coupling, with bi-directional exchanges of information, brings technical precision to the long-term coherence of energy scenarios. (author)

    The aim of this study was to determine the susceptibility of insectivorous bats (using the big brown bat as a model) to infection with European bat lyssavirus type 1a (EBLV-1a), to assess the dynamics of host immune responses and to evaluate the opportunity for horizontal viral transmission within colonies. Two isolates of EBLV-1a, originating from Slovakia (EBLV-1aSK) and Germany (EBLV-1aGE), were tested. Four different routes of inoculation were used with isolate EBLV-1aSK [10(4.8) mouse intracerebral median lethal dose (MICLD(50)) in 50 mul]: intramuscular (i.m.) in the deltoid area or masseter region, per os (p.o.) and intradermal (i.d.) scratches. Isolate EBLV-1aGE (10(3.2) and 10(2.2) MICLD(50) in 20 mul) was inoculated via the intranasal (i.n.), i.m. (low- and high-dose groups, into pectoral muscles); p.o. and intracerebral (i.c.) routes. None of the bats infected by the i.n., p.o. or i.d. route with either virus isolate developed disease during the experiments (91 or 120 days, respectively). Incubation periods were 9-12 days for i.c.-inoculated bats (66 % mortality), 12-33 days for bats inoculated i.m. with the higher dose (23-50 % mortality) and 21-58 days in bats inoculated i.m. with the lower dose of virus (57 % mortality). Virus or viral RNA in bat saliva was detected occasionally, as early as 37 days before death. All i.d.-inoculated and the majority of i.m.-inoculated bats seroconverted within 7-10 days of inoculation. These observations suggest that exposure of bats to varying doses of EBLV-1 from rabid conspecifics via natural (i.d.) routes could lead to an abortive infection and serve as a natural mode of immunization resulting in the presence of virus-neutralizing antibodies in free-ranging bats.

    The European Community's research activities on the decommissioning of nuclear installations are aimed at developing effective techniques and procedures for ensuring the protection of man and his environment against the potential hazards from nuclear installations that have been withdrawn from service. The first five-year (1979-1983) programme of research on the decommissioning of nuclear power plants has comprised seven R and D projects concerning the following areas: maintaining disused plants in safe condition; surface decontamination for decommissioning purposes; dismantling techniques; treatment of the main waste materials arising in decommissioning, i.e. steel, concrete and graphite; large containers for decommissioning waste; arisings and characteristics of decommissioning waste; plant design features facilitating decommissioning. The research work was carried out by organizations and companies in the Member States under 51 research contracts, most of them cost-sharing. The Commission is now launching a new five-year (1984-1988) programme of research on the decommissioning of nuclear installations. (author)

  9. Market power across the Channel: Are Continental European gas markets isolated?

    Massol, Olivier; Banal-Estanol, Albert

    2014-01-01

    This paper examines the efficiency of the arbitrages performed between two regional markets for wholesale natural gas linked by a capacity-constrained pipeline system. We develop a switching regime specification to (i) detect if the observed spatial arbitrages satisfy the integration notion that all arbitrage opportunities between the two markets are being exploited, and (ii) decompose the observed spatial price differences into factors such as transportation costs, transportation bottlenecks, and the oligopolistic behavior of the arbitrageurs. Our framework incorporates a test for the presence of market power and it is thus able to distinguish between the physical and behavioral constraints to marginal cost pricing. We use the case of the 'Interconnector' pipeline as an application, linking Belgium and the UK. Our empirical findings show that all the arbitrage opportunities between the two zones are being exploited but confirm the presence of market power. (authors)

    Full Text Available This paper focuses on the Nord Stream 2 pipeline in a double reflection (Russia - the candle, Germany - the mirror handling one particular aspect that influences Russia-EU relations since the Ukrainian factor emerged as a playground for both East and West tectonic plates - namely the energy sector. It is vital for any global power to understand this approach in order to reach people’s minds, in order to emerge as leaders on the world map and to build a strong perception over a political scene. A recently debated subject is Nord Stream 2. The reason why I have chosen to explore this subject is because I am very interested in how Kremlin seeks to have an exclusive control over Eastern Europe, given the full debate in the last three years. In this thesis I will also discuss some important elements of the Russian Soft Power over Europe introducing the plot of South Stream project.

  11. Second strategic energy report of the European Union - more security of supply with nuclear power

    International Nuclear Information System (INIS)

    Heller, W.

    2008-01-01

    On November 13, 2008, the EU Commission presented the Second Strategic Energy Report. The Report was supplemented by one proposed directive each on the security of gas supply and on oil stockpiling, by a multitude of measures to improve energy efficiency, and by 2 communications by the Commission on offshore wind energy and the nuclear program of the EU. The Commission attaches strategic importance in securing energy supply to the domestic energy resources, renewables, coal, and nuclear power. Moreover, the Commission assigns to the use of nuclear power an important role in the transition to an economy causing only a minimum of CO 2 emissions. The updated nuclear program contains these proposals: - The most up-to-date technology is to be employed in the construction of new reactors, and - the highest standards of nuclear safety are to be applied. - The diverse licensing conditions and procedures currently existing in the member states are to be harmonized. A few days earlier, the Nuclear Energy Agency (NEA) of OECD had presented the 2008 Nuclear Energy Outlook in which the points raised by the EU Commission are outlined in the same sense for the OECD member countries. Germany clearly continues to be in an isolated position worldwide in opting out of the use of nuclear power. This raises the question when and in what way political majorities may again be found which would prevent the enforcement of laws in the interest of phasing out nuclear power, and get rid of the irrational blockages in spent fuel and nuclear waste management.

    2016-01-01

    Extranodal NK/T-cell lymphoma, nasal type (ENKTL-NT) is an aggressive extranodal non-Hodgkin lymphoma most commonly occurring in East Asia and Latin America but with increasing incidence in the U.S. Data on epidemiology, disease presentation, and outcome for European and North American (“Western”) cases are very limited. We review published landmark clinical studies on ENKTL-NT in the West and report in detail recent data, including our institutional experience. We highlight key observations in its epidemiology, natural history, and trends in clinical management. In the U.S., ENKTL-NT is more common among Asian Pacific Islanders (API) and Hispanics compared to non-Hispanic whites. Published studies indicate less heterogeneity in clinical presentation in Western ENKTL-NT compared to Asian patients. While there is variation in age at diagnosis, presence of antecedent lymphoproliferative disorders, and outcomes among racial/ethnic groups, the universal association of ENKTL-NT with EBV and the poor response of this neoplasm to anthracycline-based therapy are consistent across all geographic areas.

    It has been shown that several modifications occurred, over the span of the 17th to 19th centuries, in the agents used to opacify European-made white soda-glass beads that were transmitted as trade goods to northeastern North America. Tin was used at the beginning of the 17th century, followed by Sb later in the century, and then by As during the 18th and 19th centuries. In an attempt to define more closely the transition from Sn-rich to Sb-rich white beads, 198 white glass beads from a number of archaeological sites in western New York State were analyzed. It was shown that the arrival of Sb-white soda-glass trade beads began in this region during the period from approximately A.D. 1625-1640, and that they had completely replaced Sn-white beads by A.D. 1675. Specific bead chemistries link a number of the archaeological sites. (author)

    Full Text Available The aim of this article is to investigate the explanatory variables of the number of Facebook fans and Twitter followers for professional sports clubs based on the financial value literature. Such explanatory variables are related to local market conditions and on-field and off-field performance. Based upon a sample of North American major league clubs and the most valuable European soccer clubs as evaluated by Forbes over the 2011–2013 period (423 observations, our results indicate a range of variables with a significant positive impact on the number of social media fans: population, no competing team in the market, current sports performance, historical sports performance, facility age, attendance, operating income, expenses/league mean, and being an English football club. An improved understanding of the effectiveness of clubs’ social media presence is important for contemporary sport managers in terms of enhancing supporter communication, involvement, and accountability, as well as maximizing clubs’ revenue generation possibilities. Our findings could help sport managers to realize their clubs’ social media potential in pursuit of these objectives, specifically to understand which variables are under-exploited and why some clubs over-perform, which will allow managers to prioritize decisions to increase their number of social media fans and financial value.

  15. The closure of European nuclear power plants: a commercial opportunity for the gas-producing countries

    International Nuclear Information System (INIS)

    Pauwels, J-P.; Swartenbroekx, C.

    2000-01-01

    The planned closure of nuclear power plants in Sweden, Germany, Belgium, Spain and the Netherlands and their hypothetical closure in the United Kingdom and Switzerland - two countries where this question remains open - will require their replacement by other types of production capacity, mainly gas turbine combined-cycle power stations (GTCCs). The increase in efficiency of GTCCs and the lower carbon content of natural gas favour the use of gas for electricity generation over coal. However, carbon dioxide emissions are unavoidable and, in the context of the Kyoto Protocol, supplementary measures must be taken to compensate, where possible, for the resulting increases in emissions. The replacement of nuclear plants with a 35-40 year lifetime by up-to-date GTCCs will require some 62 billion cubic metres per year of natural gas, resulting in an emissions increase of about 130 million tonnes per year of CO 2 . The replacement of polluting coal-fired and oil-fired plants by GTCCs will reduce CO 2 emissions, but will also require some extra 42 bcm/y of natural gas, at an (unrealistic) high cost. In short, gas-producing countries will benefit from the market breakthrough of their 'clean' fuel, thanks to the GTCCs, and gas demand will be reinforced by the abandonment of nuclear power.

    2016-03-01

    Full Text Available A numbers of studies focusing on the determinant of the insurance market efficiency have increased in the last decade. In fact, many factors, like the CEO’s power, can influence the efficiency in the insurance firm. The purpose of this research is to analyze the relationship between efficiency, measured by the cost function using the stochastic frontier approach (SFA methodologies, and the market structure, as well as the macroeconomic variables. In addition, it focuses on identifying the impact of the integration of the CEO power variable in the cost function on this relation. The result shows that after the consideration of the CEO power score in the cost efficiency, the relation between insurance efficiency and the determinant of market development, as well as the domestic economy, has changed and become more significant. The result also shows that the firms become more efficient and more profitable with a higher concentration ratio and this is in accordance with the structure-conduct-performance (SCP theory.

    2003-01-01

    The competition of fusion power plants with the renewable energy sources in the second half of the 21st century requires structural materials operating at high temperatures, and sufficient radiation resistance to ensure high plant efficiency and availability. The reduced activation materials development in the EU counts several steps regarding the radiation damage resistance: 75 dpa for DEMO and 150 dpa and beyond for power plants. The maximum operating temperature development line ranges from the present day from the present day feasible 600 K up to 1300- K in advanced power plants. The reduced activation steel, RAS, forms the reference for the development efforts. EUROFER has been manufactured in the EU on industrial scale with specified purity and mechanical properties up to 825 K. The oxide dispersion strengthened , ODS, variety of RAS should reach the 925 K operation limit. The EU has selected silicon carbide ceramic composite as the primary high temperature, 1300 K, goal. On a small scale the potential of tungsten alloys for higher temperatures is investigated. The present test environments for radiation resistance are insufficient to provide data for DEMO. Hence the support of the EU for the International Fusion Materials Irradiation facility. The computational modelling is expected to guide the materials development and the design of near plasma components. The EU co-operates closely with Japan, the RF and US in IEA and IAEA co-ordinated agreements, which are highly beneficial for the fusion structural materials development. (author)

    2011-01-01

    This article presents a dynamic Generalized Nash-Cournot model to describe the evolution of the natural gas markets. The major players along the gas chain are depicted including: producers, consumers, storage and pipeline operators, as well as intermediate local traders. Our economic structure description takes into account market power and the demand representation tries to capture the possible fuel substitution that can be made between the consumption of oil, coal, and natural gas in the overall fossil energy consumption. We also take into account long-term contracts in an endogenous way, which makes the model a Generalized Nash Equilibrium problem. We discuss some means to solve such problems. Our model has been applied to represent the European natural gas market and forecast, until 2030, after a calibration process, consumption, prices, production, and natural gas dependence. A comparison between our model, a more standard one that does not take into account energy substitution, and the European Commission natural gas forecasts is carried out to analyze our results. Finally, in order to illustrate the possible use of fuel substitution, we studied the evolution of the natural gas price as compared to the coal and oil prices. (authors)

    Wohlgemuth, N.; Madlener, R.

    2002-01-01

    The impacts of the changes in the industrial organisation of the (European) electricity supply industry pull in different directions. Pairs of largely antithetic issues in the transition towards a more liberalised electricity supply industry include: competition vs monopoly; efficiency vs equity and/or public service considerations; short-term vs long-term policy goals; slow vs rapid transition to a more competition-oriented industry structure; permanent vs temporary regulation; light-handed vs heavy-handed regulation; centralised vs decentralised regulation; and public vs private ownership. Because of the increasing recognition of the importance of sustainability, this paper aims to shed some light on the various impacts of electricity sector reform on sustainable development and, in turn, on how sustainable development policies tend to affect the electricity sector. We find that for a transition towards a more sustainable development in the electricity sector it is crucial that increased energy production and use does not outweigh the (efficiency, equity, social, environmental, etc.) gains that are, or have been, achieved towards sustainable development. In this respect an internalisation of external costs, which includes the abolition of subsidies for non-sustainable energy carriers ('first-best solution'), or an explicit accounting of the benefits offered by renewable and efficiency technologies ('second-best solution'), plus rigorous energy saving and energy efficiency promotion measures, are paramount on the path towards sustainability.

    2003-01-01

    The European helium cooled pebble bed (HCPB) blanket concept is the basis for one of two limited-extrapolation plant models that are being elaborated within the European power plant conceptual study (PPCS). In addition to addressing the case for fusion safety and environmental compatibility, following earlier studies like SEAFP or SEAL, this reactor study puts emphasis on plant availability and economic viability, which are closely related to specific plant models and require a detailed lay-out of the fusion power core and a consideration of the overall plant (balance of plant). Within the development of in-vessel components for the plant model, the major tasks to be carried out were: (i) adaptation of the HCPB concept--featuring separate pebble beds of ceramic breeder and Beryllium neutron multiplier and reduced-activation ferritic-martensitic steel EUROFER as structural material--to the large module segmentation chosen for reasons of plant availability in part II of the PPCS; (ii) proposal of a concept for a Helium cooled divertor compatible with a maximum of 10 MW/m 2 heat flux to satisfy the requirements of reasonably extrapolated plasma physics; (iii) lay-out of the major plant model components and integration into the in-vessel dimensions found from system code calculations for a power plant of 1500 MW electrical output and iterated data on the plant model performance. The paper defines all major in-vessel components of plant model B, as it is called in the PPCS, namely (i) the unit of FW, blanket and high temperature shield that is to be replaced regularly; (ii) the low temperature shield that is laid out as a lifetime component of the reactor; (iii) the divertor; and (iv) the in-vessel manifolding. Results are presented for the thermal-hydraulic performance of the components and for the thermal-mechanical behaviour of the blanket and the divertor target plate. These results suggest, together with results from the wider exploration of the plant model within

    In a study sponsored by the US Nuclear regulatory Commission (NRC), Pacific Northwest Laboratory has developed and applied a methodology for deriving plant-specific risk-based inspection guidance for the auxiliary feedwater (AFW) system at pressurized water reactors that have not undergone probabilistic risk assessment (PRA). This methodology uses existing PRA results and plant operating experience information. Existing PRA-based inspection guidance information recently developed for the NRC for various plants was used to identify generic component failure modes. This information was then combined with plant-specific and industry-wide component information and failure data to identify failure modes and failure mechanisms for the AFW system at the selected plants. North Anna was selected as a plant for study. The product of this effort is a prioritized listing of AFW failures which have occurred at the plant and at other PWRs. This listing is intended for use by the NRC inspectors in preparation of inspection plans addressing AFW risk important components at the North Anna plant

    The first Euroatom European nuclear conference was held in Brussels on November 25/26, 2004 was attended by more than 250 renowned experts, including more than 20 managers of the board from a dozen European countries. They all agreed that the construction of new nuclear power plants will depend on the public opinion, i.e. it will be a political and communication problem rather than a technical problem. A swing of public opinion is difficult as rational arguments do not apply when emotions are high. The economic efficiency of nuclear power was proved again by the new reactor constructed in Finland.

    1994-01-01

    In the Netherlands only pulverized coal-fired dry bottom boilers are installed. The flue gases are cleaned by high-efficiency cold-side electrostatic precipitators (ESPs) and in all large coal-fired power plants by flue-gas desulfurization (FGD) installations of the lime(stone)/gypsum process. KEMA has performed a large research program on the fate of (trace) elements at coal-fired power plants. A great deal of attention has been paid to the concentrations and distribution of trace elements in coal, in ash and in the vapor phase in the flue gases. Sixteen balance studies of coal-fired power plants, where coal imported from various countries is fired, have been performed. With the information provided by these studies the enrichment factors for the trace elements in ash and the vaporization percentage of the minor and trace elements in the flue gases have been calculated. Using these enrichment factors and vaporization percentages combined with data on the concentration in the coal, the concentrations in the ash and in the vapor phase in the flue gases can be predicted. The emission into the air of trace elements occurs in the solid state (fly ash) and in the gaseous state. The emissions in the solid state are low due to the high degree of removal in the ESPs. The emissions in the gaseous phase are, relatively speaking, more important. In an FGD both emissions are further diminished. In the next section the behavior of elements in the boiler and ESP will be discussed. The influence of the electrostatic precipitators will be reviewed the section thereafter, followed by the fate of gaseous minor and trace elements. And finally the behavior of elements in the FGD will be treated in the last section

    Highlights: • Breeder blanket concepts for DEMO—design features. • Neutronic characteristics of breeder blankets. • Evaluation of Tritium breeding potential. • Evaluation of shielding performance. - Abstract: This paper presents nuclear performance issues of the HCPB, HCLL, DCLL and WCLL breeder blankets, which are under development within the PPPT (Power Plant Physics and Technology) programme of EUROfusion, with the objective to assess the potential and suitability of the blankets for the application to DEMO. The assessment is based on the initial design versions of the blankets developed in 2014. The Tritium breeding potential is considered sufficient for all breeder blankets although the initial design versions of the HCPB, HCLL and DCLL blankets were shown to require further design improvements. Suitable measures have been proposed and proven to be sufficient to achieve the required Tritium Breeding Ratio (TBR) ≥ 1.10. The shielding performance was shown to be sufficient to protect the super-conducting toroidal field coil provided that efficient shielding material mixtures including WC or borated water are utilized. The WCLL blanket does not require the use of such shielding materials due to a very compact blanket support structure/manifold configuration which yet requires design verification. The vacuum vessel can be safely operated over the full anticipated DEMO lifetime of 6 full power years for all blanket concepts considered.

    In response to the ENFSI and EDNAP groups' call for new STR multiplexes for Europe, Promega(®) developed a suite of four new DNA profiling kits. This paper describes the developmental validation study performed on the PowerPlex(®) ESI 16 (European Standard Investigator 16) and the PowerPlex(®) ESI 17 Systems. The PowerPlex(®) ESI 16 System combines the 11 loci compatible with the UK National DNA Database(®), contained within the AmpFlSTR(®) SGM Plus(®) PCR Amplification Kit, with five additional loci: D2S441, D10S1248, D22S1045, D1S1656 and D12S391. The multiplex was designed to reduce the amplicon size of the loci found in the AmpFlSTR(®) SGM Plus(®) kit. This design facilitates increased robustness and amplification success for the loci used in the national DNA databases created in many countries, when analyzing degraded DNA samples. The PowerPlex(®) ESI 17 System amplifies the same loci as the PowerPlex(®) ESI 16 System, but with the addition of a primer pair for the SE33 locus. Tests were designed to address the developmental validation guidelines issued by the Scientific Working Group on DNA Analysis Methods (SWGDAM), and those of the DNA Advisory Board (DAB). Samples processed include DNA mixtures, PCR reactions spiked with inhibitors, a sensitivity series, and 306 United Kingdom donor samples to determine concordance with data generated with the AmpFlSTR(®) SGM Plus(®) kit. Allele frequencies from 242 white Caucasian samples collected in the United Kingdom are also presented. The PowerPlex(®) ESI 16 and ESI 17 Systems are robust and sensitive tools, suitable for the analysis of forensic DNA samples. Full profiles were routinely observed with 62.5pg of a fully heterozygous single source DNA template. This high level of sensitivity was found to impact on mixture analyses, where 54-86% of unique minor contributor alleles were routinely observed in a 1:19 mixture ratio. Improved sensitivity combined with the robustness afforded by smaller amplicons

    Results of an empirical survey, one of the first to deal with the Role of the Operator in nuclear power plants in North America, are presented. The survey showed that the theoretical match between operators' responsibility and control (written definition of ''role'') is not supported by the numerical evaluations of these two concepts. Across a dimension from existing to advanced reactors, there is increasingly a shift from hands-on manipulation and readout-by-readout information integration by the operators to a role in which the operator is a passive monitor whose primary task is to give permissives to the automated control system. There is a decreasing degree of control for operators, while responsibility remains high. Decreased control coupled with high responsibility may create shift operating staff problems

  9. Evaluation of Manual Ultrasonic Examinations Applied to Detect Flaws in Primary System Dissimilar Metal Welds at North Anna Power Station

    2012-01-01

    During a recent inservice inspection (ISI) of a dissimilar metal weld (DMW) in an inlet (hot leg) steam generator nozzle at North Anna Power Station Unit 1, several axially oriented flaws went undetected by the licensee's manual ultrasonic testing (UT) technique. The flaws were subsequently detected as a result of outside diameter (OD) surface machining in preparation for a full structural weld overlay. The machining operation uncovered the existence of two through-wall flaws, based on the observance of primary water leaking from the DMW. Further ultrasonic tests were then performed, and a total of five axially oriented flaws, classified as primary water stress corrosion cracking (PWSCC), were detected in varied locations around the weld circumference.

    This paper discusses the application of the North Anna Power Station Individual Plant Examination (IPE) models in PRA study of the Service Water System Preservation Project (SWSPP). The service water project involves repair and restoration of the Service Water System (SWS) piping and will require excavation of the buried SWS lines in addition to temporarily removing one of the two redundant SWS loops from operation. The SWSPP will be carried out with one or both units in normal operation. The objective of the PRA study was to quantify the risk impact (as measured by the change in Core Damage Frequency (ΔCDF)) of the SWSPP and to identify and evaluate countermeasures to reduce the risk impact of the project activities. The study concluded that the ΔCDF would be acceptable by undertaking preventative measures and by providing additional accident mitigating measures during performance of the SWSPP activities

    The European Commission (E.C.) thinks that nuclear power has an important role to play: first to reduce CO{sub 2} emissions and secondly to reinforce energy self-reliance of the member states. The decision to introduce nuclear power in their energy mix belongs to every state but the E.C. has also highlighted that if adequate investment are quickly made 2 thirds of the electricity produced in the European Union in 2010 could by from low-carbon-emitting sources. Today with 148 reactors operating in 15 member countries nuclear power contributes to 1 third of the electricity produced. Another issue that is looming is the security of electricity supplying. A study has shown that the security level is worsening (particularly in winter) because of the greater part of wind energy in the energy mix as wind energy is not necessarily available when energy demand is peaking. The E.C. has proposed a new directive drawing a common standard frame for nuclear safety requirements concerning design, site selection, maintenance, operation and decommissioning of nuclear facilities. Each member state will have the choice to implement stiffer regulations. The European Union must reduce its dependency on Russian gas by increasing its storing capacities, by easing gas exchanges between member states and by importing more liquefied natural gas. European member states will have to invert 1000*10{sup 9} euros in gas and electrical power infrastructures in the next 25 years. (A.C.)

    , one could point out that the current 'holding period' for nuclear power in Europe will soon come to an end. In the near future, Europe will be faced with important energy decisions. With an increasing number of nuclear power plants reaching their original design lifetimes, Europe will have to decide how to replace its retiring nuclear power plants. Making these decisions will depend, to some extent, on where you choose to place your emphasis, for example, on exploring available coal and natural gas resources, improving the performance and cost of renewables, or placing greater reliance on imports. What seems clear is that the only baseload option available today with low carbon emissions comparable to nuclear power is large hydropower, and sites for hydropower expansion are somewhat limited in Europe. Whether decisions involve decommissioning, extending the life of existing reactors, or building the next generation of European nuclear power plants, the IAEA will be ready to assist you in your efforts to ensure a safe and secure energy supply

    Modern methods for detecting seismic anisotropy offer an array of promising tools for imaging deep crustal deformation but also present challenges, especially with respect to potential biases in both the detection methods themselves as well as in competing processes for localized versus distributed deformation. We address some of these issues from the geophysical perspective by employing azimuthally dependent amplitude and polarity variations in teleseismic receiver functions combined with a compilation of published rock elasticity tensors from middle and deep crustal rocks, and from the geological perspective through studies of shear zone deformation processes. Examples are highlighted at regional and outcrop scales from western North America and the European Alps. First, in regional patterns, strikes of seismically detected fabric from receiver functions in California show a strong alignment with current strike-slip motion between the Pacific and North American plates, with high signal strength near faults and from depths below the brittle-ductile transition suggesting these faults have deep ductile roots. In contrast, despite NE-striking shear zones being the most prominent features portrayed on Proterozoic tectonic maps of the southwestern USA, receiver function anisotropy from the central Rocky Mountain region appears to more prominently reflect broadly distributed Proterozoic fabric domains that preceded late-stage localized shear zones. Possible causes for the discrepancy fall into two categories: those that involve a) bias in seismic sampling and/or b) deformation processes that lead to either weaker anisotropy in the shear zones compared to adjacent domains or to a symmetry that is different from that conventionally assumed. Most of these explanations imply that the seismically sampled domains contain important structural information that is distinct from the shear zones. The second set of examples stem from studies of outcrop-scale shear zones in upper

    Peer Power is an innovative school-based program that trains high school students as health educators and mentors for middle school students. The program was designed to produce positive health behavior changes in youth and reduce long-term incidence of chronic diseases of the heart and lung. This program, developed at the Management Academy for Public Health, has been successful in receiving grant funds and has demonstrated positive behavioral changes in youth in the areas of physical activity, nutrition, and tobacco use. Peer Power has far exceeded the anticipated outcomes and proven to be a catalyst for improved health behaviors throughout the community. Positive unintended consequences of Peer Power include the development of an effective social marketing campaign, reduction in tobacco sales to minors, and an increase in smoke-free restaurants in Dare County. Benefits received by Management Academy participants are evident through improved business and administrative skills at the Dare County Department of Public Health, the number of new and innovative programs that have succeeded in securing grant funds, and the sustainability of the programs developed.

  20. Hypoxic survival strategies in two fishes: extreme anoxia tolerance in the North European crucian carp and natural hypoxic preconditioning in a coral-reef shark.

    Especially in aquatic habitats, hypoxia can be an important evolutionary driving force resulting in both convergent and divergent physiological strategies for hypoxic survival. Examining adaptations to anoxic/hypoxic survival in hypoxia-tolerant animals may offer fresh ideas for the treatment of hypoxia-related diseases. Here, we summarise our present knowledge of two fishes that have evolved to survive hypoxia under very different circumstances. The crucian carp (Carassius carassius) is of particular interest because of its extreme anoxia tolerance. During the long North European winter, it survives for months in completely oxygen-deprived freshwater habitats. The crucian carp also tolerates a few days of anoxia at room temperature and, unlike anoxia-tolerant freshwater turtles, it is still physically active in anoxia. Moreover, the crucian carp does not appear to reduce neuronal ion permeability during anoxia and may primarily rely on more subtle neuromodulatory mechanisms for anoxic metabolic depression. The epaulette shark (Hemiscyllium ocellatum) is a tropical marine vertebrate. It lives on shallow reef platforms that repeatedly become cut off from the ocean during periods of low tides. During nocturnal low tides, the water [O(2)] can fall by 80% due to respiration of the coral and associated organisms. Since the tides become lower and lower over a period of a few days, the hypoxic exposure during subsequent low tides will become progressively longer and more severe. Thus, this shark is under a natural hypoxic preconditioning regimen. Interestingly, hypoxic preconditioning lowers its metabolic rate and its critical P(O(2)). Moreover, repeated anoxia appears to stimulate metabolic depression in an adenosine-dependent way.

  1. Free-ranging European bisons accumulate more cadmium in the liver and kidneys than domestic cattle in north-eastern Poland

    It has been shown that free-ranging big game animals accumulate several-fold more cadmium (Cd) in the liver and kidneys than domestic animals. To examine possible reasons for this difference, in the present work we determined the concentrations of Cd in the liver and kidney cortex of European bisons (n = 23) from Bialowieza Forest (north-eastern Poland) and domestic cattle (n = 15) from the same region; in addition, analyses of Cd in the grasses and soil as well as of soil pH were carried out. The accumulation of Cd in liver and kidney cortex of the female bisons correlated significantly with the age up to 7 years, but stabilized thereafter. The 7-12-year-old bisons had 2.14- and 2.25-fold higher concentrations of Cd in the liver and kidney cortex, respectively, than the age-matched domestic cattle. Notably, the Cd levels in the liver and kidneys of the 8-12-year-old cattle were comparable to those found in the 2-year-old and 4-6-year-old bisons, respectively. The content of Cd in the grasses from Bialowieza Forest appeared to be 2.1-fold higher than that in the plants from the pastures. Similarly, the concentration of water-extractable Cd in the soil was 2.7-fold greater in Bialowieza Forest than in the pastures, despite the fact that nitric acid-extractable Cd (total Cd) was similar in the soils from the two sites. The concentration of water-extractable Cd in the soil as well as the content of Cd in the grasses inversely correlated with soil pH, which appeared to be significantly lower in Bialowieza Forest. These data indicate that soil pH is probably responsible for the higher concentrations of Cd in the feed and tissues of bisons as compared with those of domestic cattle

    Background The increase in tick-borne encephalitis (TBE) incidence is observed in recent decades in a number of subarctic countries. The reasons of it are widely discussed in scientific publications. The objective of this study was to understand if the climate change in Arkhangelsk Oblast (AO) situated in the north of European subarctic zone of Russia has real impact on the northward expansion of Ixodid ticks and stipulates the increase in TBE incidence. Methods This study analyzes: TBE incidence in AO and throughout Russia, the results of Ixodid ticks collecting in a number of sites in AO, and TBE virus prevalence in those ticks, the data on tick bite incidence in AO, and meteorological data on AO mean annual air temperatures and precipitations. Results It is established that in recent years TBE incidence in AO tended to increase contrary to its apparent decrease nationwide. In last 10 years, there was nearly 50-fold rise in TBE incidence in AO when compared with 1980–1989. Probably, the increase both in mean annual air temperatures and temperatures during tick active season resulted in the northward expansion of Ixodes Persulcatus, main TBE virus vector. The Ixodid ticks expansion is confirmed both by the results of ticks flagging from the surface vegetation and by the tick bite incidence in the population of AO locations earlier free from ticks. Our mathematical (correlation and regression) analysis of available data revealed a distinct correlation between TBE incidence and the growth of mean annual air temperatures in AO in 1990–2009. Conclusion Not ruling out other factors, we conclude that climate change contributed much to the TBE incidence increase in AO. PMID:22028678

    Full Text Available One of the competencies that the EU Treaties confer to the European Commission is the control and supervision of the application of primary and secondary law and the enforcement of this legislation so it is observed by private persons, Member States and EU institutions2 . Further to an official communiqué in October 2014, the European Commission has announced that it sued Romania at the European Union Court of Justice concerning the failure to observe EU legislation on the treatment of extractive industry waste. Namely, it refers to the Moldova Noua case, in which toxic waste from the zinc and copper mines were discharged into the Bosneag pond. This paper means to present the regulations in the field of extractive industry, the competence of the European Commission regarding the enforcement of EU legislation and the ability to sue a Member State at the EU Court of Justice, when the entity exploiting the zinc and copper deposits is not the Romanian state, but a private law legal person.

    Precipitation sequence is a typical nonlinear and chaotic observational series, and studies on precipitation forecasts are restricted to the use of traditional linear statistical methods, especially when analysing the regional characteristics of precipitation. In the context of 20 stations' daily precipitation series (from 1956 to 2000) in South China (SC) and North China (NC), we divide each precipitation series into many self-stationary segments by using the heuristic segmentation algorithm (briefly BG algorithm). For each station's precipitation series, we calculate the exponent of power-law tail (EPT) of the cumulative probability distribution of segments with a length larger than l for precipitation and temperature series. Our results show that the power-law decay of the cumulative probability distribution of stationary segments might be a common attribution for precipitation and other nonstationary time series; the EPT somewhat indicates the precipitation duration and its spatial distribution that might be different from area to area. The EPT in NC is larger than in SC; Meanwhile, EPT might be another effective way to study the abrupt changes in nonlinear and nonstationary time series. (geophysics, astronomy and astrophysics)

    A review of the construction and operation of nuclear power plants in Slovak Republic which belong within Slovenske Elektrarne is made. Since 1993 with the applying of the Least Cost Planning Methods and Financial Feasibility Analysis the optimal variant, considering construction completion of the two units at Mochovce NPP, has been adopted and a project for safety enhancement has been implemented. Some changes have been made in siting project in order to meet the seismic requirements, following by change of the control system design and supplier. The most important result of the safety enhancement program, important not only for NPP Mochovce, but also for all NPPs of WWER 440/213 type, is the fact, that operability of containment with passive bubbler-condenser system for pressure suppression and its acceptability from safety point of view, has been fully confirmed. Results of safety enhancement program have been re-evaluated not only by International Atomic Energy Agency, but also by other international authorities and professional organisations with positive result. Especially significant is the conclusion of RISKAUDIT, which has carried out repeated evaluation of safety level of NPP Mochovce based on PHARE project and which is accepted by European Commission. A similar approach for enhancing the safety has been applied for the NPP V-1 units at Jaslovske Bohunice

  8. Research priorities at the European Commission in relation to maintenance optimization and nuclear power plant life management

    International Nuclear Information System (INIS)

    Contri, Paolo

    2009-01-01

    Analysis of experience in many countries operating nuclear power plants (NPPs) suggests that, while differences in long term operation (LTO) programs are mainly related to the various national regulatory processes, the main features and basic technical requirements are similar. The implementation of these however needs reshaping in an integrated plant life management (PLIM) framework, bearing in mind the specific safety implications of LTO. R and D is essential to support this process, not only for long term extrapolation of the component integrity and behaviour, but also for a proper maintenance system and for an adequate management structure ensuring effective management strategies at plant level, able to address organisational issues, spare part management, staff ageing, component obsolescence, etc. This is recognised by the European Commission, which supports R and D in targeted areas in the framework of the EURATOM programme, both by “direct actions” i.e. projects managed and executed by its Directorate General Joint Research Centers (JRC) and by indirect actions i.e. funding of selected projects, managed by the Directorate General Research (RTD). This paper outlines the JRC's priorities in the current 7th Framework Programme in relation to R and D tasks for maintenance and ISI to support the highest safety level at member's NPPs and appropriate decision-making tools for the optimisation of these programs. A newly developed UE model for PLIM, also integrating maintenance optimisation issues, is presented for further discussion. (author)

  9. Nuclear power use backed by EURATOM law. European Court of Justice ruling points the way ahead in cross-border litigation

    International Nuclear Information System (INIS)

    Schneider, Horst

    2010-01-01

    The Europeanization of nuclear safety has become highly evident with the adoption of the EURATOM Safety Directive of June 25, 2009. It will remain in the focus of public attention because its transposition into national law is to be completed by July 22, 2011. The subject of nuclear safety is treated also by the European Court of Justice (ECJ). The Court's rulings may even set the courses of events. It is not only EURATOM rules and regulations and secondary European law in the format of directives which are up for review, but also more extensive principles of European law. The main sources of dispute are the different nuclear energy policies and non-uniform safety regulations of member states. Cross-border events again and again trigger such disputes. One such constellation constitutes the background to the latest ECJ ruling of October 27, 2009 about nuclear safety and radiation protection. Action before an Austrian court was brought against a nuclear power plant situated in the Czech Republic and licensed by Czech authorities. Cessation of emissions of hazardous ionizing radiation by that plant and, thus, ultimately shutdown of that plant were demanded. The special feature of the case is the fact that the action was filed with an Austrian (civil) court and heard there. As the ECJ had commented in 2006 on a procedural question before legal proceedings were started, the issue at stake now was the right to bring action out of Austria against the nuclear power plant licensed in the Czech Republic. In Austrian law, there is no such right of cessation with respect to plants licensed in Austria, but only a right to claim damages. Against this background some thoughts are expressed about, and forecasts attempted of, European nuclear and radiation protection law. In this assessment, the difficult, multifaceted issues of European law rank second to the explanations of practical consequences for the development of nuclear power in EU member states. (orig.)

    Bramwell, Roberta; Foreman, Kathleen

    1993-11-01

    This paper begins with case studies of innovative approaches to the education of Aboriginal Canadian Peoples and Philippine Aboriginal Peoples. These illustrate that, in such situations, where more traditional approaches have little success, the power to design, implement and evaluate educational programs can beneficially be shared between teacher and learner. Learners co-operate with each other in deciding what they need to learn. They examine their own needs and issues and assess their learning in terms of their cultural, economic and community value systems. Leadership is shared with the teacher/facilitators and word, image, number, gesture and sound are all employed to acquire knowledge and to demonstrate what that knowledge means to the group. In this particular enterprise, popular theatre has a major role to play in democratizing the provision of education and in encouraging educational development in circumstances where other approaches have been ineffectual. In the latter part of the paper, a model of education implied by the case studies is constructed and examined to provide alternatives to the traditional views of epistemology, of ethics and of pedagogy based on a notion of democracy as a daily struggle.

    In the light of the introduction of thousands of large offshore wind power foundations into the North Sea within the next decades, this manuscript focuses on the biofouling processes and likely reef effects. The study explores the macrozoobenthos (biofouling) colonization at an offshore platform which is comparable to offshore wind turbine foundations. A total of 183 single samples were taken and the parameters water depth and time were considered comparing biofouling masses and communities. The blue mussel Mytilus edulis, Anthozoa and the Amphipoda Jassa spp. were the dominant species. The community from the 1 m zone and those from the 5 and 20-28 m zones can clearly be differentiated. The 10 m zone community represents the transition between the M. edulis dominated 1 m and 5 m zones and the Anthozoa dominated 20-28 m zone. In the future offshore wind farms, thousands of wind turbine foundations will provide habitat for a hard bottom fauna which is otherwise restricted to the sparse rocky habitats scattered within extensive sedimentary soft bottoms of the German Bight. However, offshore wind power foundations cannot be considered natural rock equivalents as they selectively increase certain natural hard bottom species. The surface of the construction (1280 m²) was covered by an average of 4300 kg biomass. This foundation concentrates on its footprint area (1024 m²) 35 times more macrozoobenthos biomass than the same area of soft bottom in the German exclusive economic zone (0.12 kg m(-2)), functioning as a biomass hotspot. Concerning the temporal biomass variation, we assume that at least 2700 kg biomass was exported on a yearly basis. 345 × 10(4) single mussel shells of different sizes were produced during the study period. It is anticipated that the M. edulis abundance will increase in the North Sea due to the expansion of the offshore wind farm development. This will result in the enhanced production of secondary hard substrate (mussel shells

  12. Sweden and the NEGP: A Pilot Study of the North European Gas Pipeline and Sweden's Dependence on Russian Energy

    Energy Technology Data Exchange (ETDEWEB)

    Larsson, Robert L.

    2006-06-15

    Developments between 2004 and 2006 indicate that a North European Gas Pipeline (NEGP) through the Baltic Sea, from Russia to Germany, may be realised in the coming decade. This would provide Europe with yet another opportunity to diversify its import channels of gas. It is however reasonable to assume that the NEGP also could change the strategic pattern and be a source of friction. The NEGP may rock the regional stability and reduce the potential of the new EU members to become security providers in Europe's northern dimension. It also gives increased leverage and influence to Russia, a state that has moved in an authoritarian direction under President Putin. The aim of this pilot study is to elucidate on the NEGP pipeline and Sweden's increasing dependence on Russian energy. A subsidiary aim is to outline a set of concerns that have bearing on the situation for the EU and Baltic Sea Region and that need to be further addressed. In conclusion, the NEGP will enhance Russia's direct leverage on Poland, Ukraine, and Belarus, as it will allow Russia to turn off gas supplies without affecting exports to other parts of Europe. Russia will also increase its leverage over the states that will or may be connected to the NEGP (Germany, and possibly Belgium, Denmark, the Netherlands and the UK). Even if Sweden is not embracing the NEGP, it is today highly sensitive as it imports most of its energy. It is increasingly dependent on Russian oil and is partly dependent on imports of electricity from Russia. Should the NEGP materialise and Sweden becomes connected in the future, it would likely be dependent also on natural gas. It is of paramount importance for the energy security of the connected states how the pipeline is constructed and operated. If there will be technical possibilities for Russia to tamper with the flow of gas to individual states without affecting supply to others, there are tangible threats to the importing states.

    Policy measures to stimulate the proliferation of combined heat and power generation (CHP) have been motivated because of the energy efficiency potential. In this paper we investigate to what extent the penetration of CHP has taken place in the 12 member states of the European Union (EU-12). Also analyzed is the potential heat demand which can be covered by CHP, and the corresponding amount of capacity for each country. A short overview is given of the goals for CHP capacity for some of the EU-12 member states. We distinguish two different kinds of policy instruments: standard settings and economic instruments. Four different types of standard settings are given. We evaluate a specific standard setting which is applied in the Netherlands in the 1970's and early 1980's. The economic instruments are evaluated in terms of payback time. This payback period can be influenced by for instance an investment grant, tax on the emission of carbon dioxide, a raise of selling electricity to the public grid and lower the price for natural gas for CHP applications. Finally, we give some recommendations how EU policy may stimulate the application of CHP. In section 2 we describe the development of CHP from 1974 to 1990 in the EU-12 member states. and the intentions stated by the national governments. In section 3 we give an overview of the potential capacity of CHP. In section 4 we discuss the regulation instruments: standard settings and economical instruments. In section 5 we give some conclusions especially with regard to EU policy options. 23 refs

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

    The European Network for Inspection Qualification, ENIQ, which groups the major part of the nuclear power plant operators in the European Union and in the Applicant Countries, has developed the European methodology for Qualification of Non Destructive Tests. As qualification of NDT is nowadays a standard method in the nuclear industry and in other industries. CEN (European Committee for Standardization) Technical Committee 138 '' Non Destructive Testing '' has established a Working Group, which is responsible for developing a Standard document detailing the CEN Methodology for the qualification of Non Destructive Tests applicable to all industries carrying out Non-Destructive Tests. This Standard document sets out basic principles and provides recommendations and general guidelines for carrying out qualification of NDT. It describes a methodology for qualification of Non-Destructive Tests, applicable to all NDT methods and considers qualification of equipment, procedure and personnel training. This paper presents a short background of the European Methodology for Qualification of Non-Destructive Tests and the Standard document CEN/TR 14748 '' Non-destructive testing - Methodology for qualification of non-destructive tests ''.

    In the frame of the ongoing debate on the 2030 energy and climate policies in the European Union, this article provides the first assessment of the effectiveness of European energy and climate policies on the CO 2 emissions reductions. This ex-post analysis deals with the CO 2 emissions of the electricity sector covered by the European Union Emission Trading Scheme (EU ETS) during its phases I and II (2005-2012). We analyze the contribution of different variables (including climate and energy policies, energy prices, economic activity and technical features of plants) in the evolution of CO 2 emissions from electricity production plants in Europe. The empirical results allow drawing a number of conclusions regarding the causes of the downward trend in the carbon emissions generated by power production covered by the EU ETS between 2005 and 2012. First, we show that the increased use of renewable energy in electricity production has played a dominant role in the fall in CO 2 emissions in the power sector. Second, the analysis confirms that the economic downturn has played a significant role, although not a dominant one. Third, price substitution effects between coal and gas also seem to have affected carbon emissions. Last but not least, we identify that the price of carbon has also pushed down power CO 2 emissions.

    The most promising way to increase the output power of an X-ray FEL (XFEL) is by tapering the magnetic field of the undulator. Also, significant increase in power is achievable by starting the FEL process from a monochromatic seed rather than from noise. This report proposes to make use of a cascade self-seeding scheme with wake monochromators in a tunable-gap baseline undulator at the European XFEL to create a source capable of delivering coherent radiation of unprecedented characteristics at hard X-ray wavelengths. Compared with SASE X-ray FEL parameters, the radiation from the new source has three truly unique aspects: complete longitudinal and transverse coherence, and a peak brightness three orders of magnitude higher than what is presently available at LCLS. Additionally, the new source will generate hard X-ray beam at extraordinary peak (TW) and average (kW) power level. The proposed source can thus revolutionize fields like single biomolecule imaging, inelastic scattering and nuclear resonant scattering. The self-seeding scheme with the wake monochromator is extremely compact, and takes almost no cost and time to be implemented. The upgrade proposed in this paper could take place during the commissioning stage of the European XFEL, opening a vast new range of applications from the very beginning of operations.We present feasibility study and examplifications for the SASE2 line of the European XFEL.

    Full Text Available Nowadays, enlargement is one of the most important issue for European Union. The situation that makes this issue important is the influence of membership of the candidate states on the voting power distribution. With the enlargements, European Union decision-making processes were regulated several times. The last regulation to the European Union voting system was brought by the Treaty of Lisbon. In this study, voting power distribution in Council of the European Union is evaluated for candidate states and member states considering the acts adopted by the Treaty of Lisbon and determined as candidate states determined as Turkey, Croatia, Iceland, Former Yugoslav Republic of Macedonia. In the analysis, member states are grouped the according to the enlargement of the EU and the effect of the states that take part in these groups on the decision and changes of voting power are calculated using Banzhaf power index for power measurement.

  2. Economics of intermittent renewable energy sources: four essays on large-scale integration into European power systems

    International Nuclear Information System (INIS)

    Henriot, Arthur

    2014-01-01

    This thesis centres on issues of economic efficiency originating from the large-scale development of intermittent renewable energy sources (RES) in Europe. The flexible resources that are necessary to cope with their specificities (variability, low-predictability, site specificity) are already known, but adequate signals are required to foster efficient operation and investment in these resources. A first question is to what extent intermittent RES can remain out of the market at times when they are the main driver of investment and operation in power systems. A second question is whether the current market design is adapted to their specificities. These two questions are tackled in four distinct contributions.The first chapter is a critical literature review. This analysis introduces and confronts two (often implicit) paradigms for RES integration. It then identifies and discusses a set of evolutions required to develop a market design adapted to the large-scale development of RES, such as new definitions of the products exchanged and reorganisation of the sequence of electricity markets.In the second chapter, an analytical model is used to assess the potential of intra-day markets as a flexibility provider to intermittent RES with low production predictability. This study highlights and demonstrates how the potential of intra-day markets is heavily dependent on the evolution of the forecast errors.The third chapter focuses on the benefits of curtailing the production by intermittent RES, as a tool to smooth out their variability and reduce overall generation costs. Another analytical model is employed to anatomise the relationship between these benefits and a set of pivotal parameters. Special attention is also paid to the allocation of these benefits between the different stakeholders.In the fourth chapter, a numerical simulation is used to evaluate the ability of the European transmission system operators to tackle the investment wave required in order to

    Energy Technology Data Exchange (ETDEWEB)

    Mathiesen, Vivi (ed.)

    2011-07-01

    This report shows that the principals of nodal pricing can be implemented in different ways. A common denominator for markets with nodal pricing is a central market based nodal dispatch, where prices and flows are determined simultaneously close to real time. This stands apart from the European market design, which is based on a highly simplified version of the grid, and a physical point auction day ahead. Congestion management is handled by the TSO during the operational hour and not through the market as is the case in nodal pricing systems. Nodal pricing yields optimal dispatch and congestion management through the market, and as such an optimal utilisation of energy generation and network. However, whether this short term optimisation delivers the highest overall efficiency for the market in terms of competition in the wholesale and retail market, price discovery, possibilities for hedging, long term price signals etc. is difficult to determine. The markets investigated handle issues such as market power, risk management, investment signals and retail markets in very different ways. New Zealand and PJM are examples of markets with full nodal pricing, i.e. both generators and the demand side are exposed to nodal prices. The PJM market has more 'additional features' than the New Zealand market. Examples of these are separate capacity market to trigger investments in generation and generator price caps to deal with situations of market power. In addition PJM offers liquid and mature markets for risk management, such as aggregates of nodes where market participant can chose to be settled (rather than to be settled directly at the node). A general finding though, seems to be that risk management at peripheral nodes is challenging in nodal markets, particularly for independent retailers. In New Zealand generators and retailers were permitted to 'reintegrate' in order to cope with the nodal prices. The Australian market has central market based

    The aim of the study was to determine and analyze the level of certain motor abilities (acceleration and agility, the explosive strength of arms, and take-off power) of young elite European female basketball players. We also wanted to establish whether there were any differences between 3 groups of female basketball players who differed in terms of their playing performance. The sample of subjects consists of 65 female basketball players aged 14.49 (± 0.61) years who were divided into 3 groups (divisions A, B, and C of the European Championships). We compare the groups by using 8 motor tests. p Values training status, this is also 1 of the key reasons for these players' lower playing efficiency compared to those from divisions A and B. We hope the findings of this study will enable the generation of model values, which can assist basketball coaches for this age category in basketball clubs, high schools, national teams, and basketball camps.

    After having recalled the organisation of nuclear safety and radiation protection regulation in France, presented the French nuclear safety regulations (acts, decrees, orders, ASN decisions, rules and guides), described the nuclear safety approach in France (the 'defense in depth' concept), and ASN's sanctions powers, this report presents the French approach to complementary safety assessments (CSAs) with their different types of specifications (those consistent with European specification, those broader than the European specifications, and those which take into account some situations resulting from a malevolent act), and with the different categories of facilities concerned by these CSAs. It presents the organisation of the targeted inspections and outlines the transparency of this action and public information. Then, after an overview of the French nuclear power plant fleet, it discusses how earthquakes, flooding, and other extreme natural phenomena related to flooding are taken into account in the design of facilities and in terms of evaluation of safety margins. It describes the consequences of some critical situations (loss of electrical power supplies and cooling systems) and how they could be dealt with. It also addresses the different aspects of a severe accident management (organisation, measures, and actions to be performed) and the conditions related to the use of outside contractors

  11. Experience and activities in the field of plutonium recycling in civilian nuclear power plants in the European Union

    The European Union industry has established a world-wide leadership position in manufacturing and exploiting plutonium bearing fuel (MOX). About 15 to 20 tons of plutonium have been manufactured in the MOX fuel fabrication plants of E.U. companies. The current capacity of about 60 tons of MOX fuel per year is being upgraded to reach 400 tons/year by the year 2000. As a result, the excess amounts of separated plutonium, presently stored in the European Union, should no longer raise but should steadily decrease to converge to zero. Studies by the European Commission have indicated that the best use at present of weapons-grade and reactor-grade plutonium is to burn it in operating and future planned nuclear reactors. Disposing of plutonium by blending it with fission products or immobilising it into synthetic matrices appears to be far from being an industrially viable option. Following this path would mean to continue storing the excess plutonium of both military and civilian origin for an unknown, but very long period of time. For these and other reasons, the European Commission is striving to foster international cooperation between the European Union companies, having a long industrial experience accumulated in the field of recycling plutonium, and, so far, the Russian Federation and the Newly Independent States. This cooperation is aiming at supporting projects that could be mutually beneficial to all parties involved. To meet this objective, several programmes have been established either bilaterally or multilaterally, in particular within the framework of the International Science and Technology Centre (I.S.T.C.) in Moscow. Some examples of such collaborations will be described. (author)

    On 23 June 2003, the European Parliament and Council issued the directive on grid access for transfrontier electricity trading (EltHVO). It is part of a bundle of directives comprising also directives on electricity and natural gas trading (EltRL and GasRL). This marks the third and final state of unbundling of the European internal power market. In December 2003, the European Commission also announced the issuing of a directive on access to natural gas pipelines (GasHVO) which was issued on 28 September 2005 and came into force on 1 July 2006. While the European Parliament views the legislation as a key project for standardizing the European internal market, others see a danger of centralisation and standardisation of concrete regulation decisions. The publication investigates the consequences of the EltHVO and GAsHVO for the internal power market, especially with a view to the possible danger of centralisation. (orig.)

    Integration in the power system has become a limiting factor to the further development of photovoltaics. Proper quantification is needed to evaluate both issues and solutions; the share of annual electricity demand is widely used but we found that some of the metrics which are related to power...... rather than energy better reflect the impact on networks. Barriers to wider deployment of PV into power grids can be split between local technical issues (voltage levels, harmonics distortion, reverse power flows and transformer loading) and system-wide issues (intermittency, reduction of system...... resilience). Many of the technical solutions to these issues rely on the inverters as actuators (e.g., for control of active and reactive power) or as interfaces (e.g., for local storage). This role requires further technical standardisation and needs to be taken into account in the planning of power...

    Directory of Open Access Journals (Sweden)

    Andrzej Borodo

    2013-10-01

    Full Text Available The issues of public debt and budget deficit are regulated by constitutions (e.g. of Poland, Germany, Spain as well as by the law of the European Union. The constitutional regulations concerning public debt and deficit are norms primarily directed at governments and parliaments. However, these regulations mainly have a preventive and auxiliary character and cannot by themselves stop the debt level of the state from increasing. Financial aims concerning debt and deficit can be achieved by non-financial methods, i.e. through the appropriate social and economic policies implemented by the authorities enjoying considerable social respect. The EU regulations regarding public debt and deficit can only be implemented with the instruments of the national law. The set of the EU regulations limiting the budgetary powers of member states, including the budgetary powers of governments and national parliaments, are questionable and undermine the authority of the state.

    2011-01-01

    The large-scale wind power development in China has reached a bottleneck of grid integrating capability. As a result, excess wind electricity has to be rejected in the nighttime low demand hours, when the wind power is ramping up. To compensate for the fluctuation of wind power, new coal-fired power plants are being constructed along with the big wind projects in the North China grids. This study analyzed why adding coal-fired generation cannot remove the bottleneck of wind integration by modeling the operating problem of the wind integration. The peak-load adjusting factor of the regional grid is defined. Building more coal-fired power plants will not increase the adjusting factor of the current grid. Although it does help to increase the total integrated wind power in the short term, it will add difficulties to the long-term wind integration. Alternatively, the coordinated resource utilization is then suggested with the discussion of both the effective pumped hydro storage and the potential electric vehicle storage. - Highlights: → Adjusting factors indicate the grid wind integrating capability. → Building coal-fired generation restrains long-term wind integration. → HVDC and nuclear projects should be planned integrated with the wind. → Pumped storage and electric vehicles provide potential solutions.
