The Influence of Migration Crisis in Europe on EU-Turkey Relations

Directory of Open Access Journals (Sweden)

Pavel P. Timofeyev

2016-01-01

Full Text Available The paper examines the impact of the migration crisis in the EU on the European Union's relations with Turkey. It is shown that for a number of reasons, including a result of EU actions taken from 2011 to 2015, EU has experienced an influx of migrants on a number of routes from the Western to the Eastern Mediterranean. The largest of them fell on Turkey, which has tried to use this factor to exert pressure on the EU in order to obtain economic and political preferences. The author examines the development of the EU migration policy in the context of the crisis, its trying to bring Turkey to cooperate and difficult negotiations, which took place at the summits of the EU-Turkey at the end of 2015. There have been disagreements among the EU countries, and the time factor, which Turkey took advantage of, advancing conditions for the closure of borders to Europe for migrants. Facing the influx of migrants the EU had to agree with a number of conditions, though not with all. The author shows that the agreement reached by the country in March 2016 is not universal, and a number of issues important to the resolution of the crisis, are waiting to be decided upon. However, according to the author, the development of the current crisis can lead both to the reform of the migration and border policy within the EU, and to restarting relations with Turkey. Though guessing on possibilities on Turkey's entry to the EU in the near future is still premature.

EU Energy Law and Policy Issues. Volume 3

Energy Technology Data Exchange (ETDEWEB)

Delvaux, B.; Hunt, M.; Talus, K. (eds.)

2011-12-15

This third volume of EU Energy Law and Policy Issues presents an overview of some of the most recent developments taking place in the EU energy sector at a time when the Third Energy Package is likely to be or has been implemented in the EU Member States. In this respect, the reader will find a number of contributions which offer detailed and critical views on some of the main issues tackled by the Third Energy Package. Aside from this, the relationship between sector specific regulation and the rules of general competition law is examined in the second section of the book. This part also contains particular contributions on access regimes in gas and electricity markets as well as an innovating analysis on the methods for allocating allowances under the EU Emissions trading scheme and the interaction of such methods with EU state aid rules. Just like the previous volumes of the book, section III offers a deep insight into the external aspects of EU energy policy. Accordingly, the role of the Lisbon Treaty in promoting EU energy policy in the international arena is scrutinized in addition to the most recent evolutions on the topical issue of the Energy Charter Treaty. This section is completed with a daring contribution about the need to adopt a comprehensive theory of legal harmonization between the EU and third partners, which is presented using the specific case of the EU-Russia Energy Dialogue. Last but not least, some fundamental issues regarding the environmental aspects of EU Energy policy undergo an in-depth study in the final section of the book. Not only is the legal regime of energy efficiency in energy-related products examined, but also the issue of carbon constraining policies under WTO law. Finally, the electricity's industry viewpoint on the 2020 targets rounds off this third volume of EU Energy Law and Policy Issues with judicious comments.

NONE

2012-04-15

Trends towards green shipping and green shipbuilding provide new market opportunities for the European shipbuilding and marine equipment sectors. The maritime transport sector is being incentivised to improve its environmental performance as a result of both market driven and regulatory greening trends. Examples of these trends are global regulation on NOx and SO2 emissions of ships, increased energy efficiency of new ships, ballast water management and an increased demand for offshore renewable energy generation. The European shipbuilding and marine equipment sectors have a leading position in high value, high complexity segments. It has a good starting position to contribute to the greening trends. This study identifies market opportunities for the EU shipbuilding industry that follow from greening trends in shipping and other areas. Taking the greening together, the global market potential for the period until 2020 is estimated to be minimally euro 12.5-15.5 bn per year. The study recommends that the EU enhances its cluster support provision, continues the promotion of the shipbuilding and marine equipment sectors as attractive work places, continues promoting the use of market based instruments at IMO level and consider adopting schemes at EU level. This report is built on an extensive market consultation process through in-depth interviews with over 35 stakeholders, complemented with a review of the state of the art literature and a stakeholder workshop. As such it is not a statistical analysis, or an academic or political analysis, but it represents an in-depth insight based on key market actors and industry players.

Genezini, Frederico Antonio

2004-07-01

The {sup 155}Eu nuclide was investigated by the directional angular correlation technique following the {beta} decay of {sup 155}Sm. The angular correlation measurements were carried out using a setup with 4 Ge detectors and a multi parametric data acquisition system. To perform the data analysis a new methodology was developed . The multipole mixing ratios of twenty sixty {gamma}- transitions were determined. Seven of them agreed with the results of earlier angular correlation studies and nineteen obtained for the first time confirmed the multipolarity suggested in earlier electron capture studies. Besides, the spin of the level at 1106.83 keV as well as the parity of the level at 1301.41 keV have also been suggested. The nuclear structure of {sup 155}Eu was discussed successfully in terms of the single particle model using a deformed Woods-Saxon potential plus residual pairing interaction permitting the description of the rotational quasi-proton band heads.

The objective of this Memorandum is to provide a background document for the Danish Environmental Protection Agency (EPA) for use in assessing the impact of the EuP Directive 2005/32/EC of 6 July 2005. Firstly, it aims to highlight the areas of general environmental impact affected by the directive and shall assist the EPA in prioritising the focus, efforts and instruments to be applied in relation to the implementation of the EuP directive in Denmark. Secondly, it aims at extracting and highlighting horizontal themes from the product oriented policy adopted by the European Commission. The conclusions have been derived by the authors and do not necessarily represent the views of the EPA. However, it is the intention that the conclusions can be used as guidance for selecting the strategic focus points. Many aspects of energy-using products (EuPs) have a negative impact on the environment (emissions to air including greenhouse gases, to soil, water, and energy consumption, etc.). The Council and the European Parliament adopted a Commission proposal for a Directive on establishing a framework for setting Eco-design requirements (e.g. energy efficiency) for all energy using products in the residential, tertiary, and industrial sectors. The Commission launched an invitation to tender for 20 preparatory studies corresponding to the major categories of Energy using Products. The studies provide the Commission with the necessary information background to prepare for the next phases, the impact assessment, the consultation with the Eco-design Forum and a draft implementing measures. References to all the Preparatory Studies are found in section 20. The background papers produced in the preparatory studies describes relevant environmental impact issues, but the conclusions are often focused on energy aspects only. Hence, the Danish EPA is interested in a wider assessment and medium to long-term perspectives of the product groups in terms of total environmental impact

2010-01-01

In this study, we report the comparison between Eu 3+ -doped silica nanoparticles synthesized by Stoeber method using Eu(NO 3 ) 3 or Eu(acac) 3 as precursors. The impact of different europium species on the properties of the final silica nanospheres is investigated in details in terms of size, morphology, reachable doping amount, and luminescence efficiency. Moreover, the results obtained for different thermal treatments are presented and discussed. It is shown that the organic complex modify the silica growing process, leading to bigger and irregular nanoparticles (500-800 nm) with respect to the perfectly spherical ones (400 nm) obtained by the nitrate salt, but their luminescence intensity and lifetime is significantly higher when 800-900 o C annealing is performed.

Klok, Jacob

2001-11-01

The primary objective of this project is to identify the main political economic driving forces behind and barriers against the creation of an EU agreement on CO 2 /energy taxation. The analysis is based on a theoretical framework for understanding European integration and on detailed historical investigations into a process of EU negotiations concerning CO 2 /energy taxation that took place from the 1980s to 1994. Following the historical analysis of political economic driving forces and barriers, some overall perspectives on possible future developments within the field of EU CO 2 /energy taxation are finally advanced. The secondary objective of the project is to consider the possible effects on the EU negotiation process of Danish efforts to push the CO 2 /energy tax proposal from the late 1980s to 994. This analysis is based on the preceding historical analysis of the EU negotiation process, as well as further investigations into the national Danish development within the field of CO 2 /energy taxation, including accounts of Denmark's particular relations with the EU during the period in question. Finally, based on the likely future developments in the field EU CO 2 /energy taxation. Denmark's strategic opportunities are outlined. (BA)

'Nothing is agreed until everything is agreed'

McQuaid, Sara Dybris

In terms of conflict resolution, we may think of Northern Ireland as a case of (deferring conflict by) institutionalising radical disagreement, in particular through the Agreement from 1998. The violence has largely if not completely stopped, but the key constitutional question of whether Northern...... Ireland should be British or Irish, is only settled for now. In the language of dialogue, the parties have “agreed to disagree” with an understanding that these matters can be reopened at some future date if there is a majority wish to do so. In the meantime, a system of designated power-sharing has been...

Transfer pricing rules in EU member states

Veronika Solilová

2010-01-01

Full Text Available One of the important area of international taxes is transfer pricing. Transfer price is a price set by a taxpayer when selling to, buying from, or sharing resources with a related (associated person. The tran­sac­tions between these persons should be assessed at their arm’s length price in according the arm’s length principle – international accepted standard – as the price which would have been agreed between unrelated parties in free market conditions. This paper is focused on the tranfer pricing rules used in particular EU Member States so as if EU Member States apply the arm’s length principle, define the related persons, apply recommendations of the OECD Guidelines, use the transfer pricing methods, require TP Documentation, exercise specific transfer pricing audit or impose specific penalties and apply APAs. Transfer pricing rules should prevent taxpayers from shifting income to related person organized in tax havens or in countries where they enjoy some special tax benefit.

EU, Eastern Europe and Values Imperialism

Directory of Open Access Journals (Sweden)

Stephen White

2014-01-01

Full Text Available This paper proposes an idea of'values imperialism'as a helpful way of conceptualising the relationship between the EU and the states that came within its sphere of influence after the end of the Cold War, particularly its 'neighbours' in Eastern Europe. Values imperialism places its emphasis on the 'superstructure', including norms, laws and social practices. EU larger objective was that the assumptions about government and ownership that were favoured by the dominant powers (EU and the West in the broad term should be absorbed and recapitulated by those countries that were subordinate. The broad framework ofsubordination was established by the Partnership and Cooperation Agreements that began to be concluded from 1994 onwards. Patterns of'values imperialism'could also be discovered in the EU Common Strategies on Russia and Ukraine that were adopted in 1999. Article also points out several cases when the EU intervened directly in the domestic affairs of the Eastern Europe countries in a manner that was not always compatible with the provisions on state sovereignty: a 'European Instrument for Democracy and Human Rights', launched in 2006, interventions ofEU representatives in the work of local courts and organisation of exit polls, which could be used to discredit the official election results and in this way to undermine the position of local governments. Finally, the author concludes that the EU used 'values imperialism'practices in order to extend its influence, particularly in the Eastern Europe.

Implementing the EU climate and energy package with the economic crisis

International Nuclear Information System (INIS)

Kerebel, C.

2009-01-01

In March 2007, the European heads of state and government agreed at their European Council upon a 20% greenhouse gas (GHG) emission reduction target compared to 1990-levels and a 20% share of renewable energies in EU's final energy consumption by 2020. To implement these commitments, the European Commission prepared a set of legislative proposals - the so-called 'Climate and Energy Package' - which was jointly endorsed by the European Parliament and the European Council in Dec. 2008 and formally adopted in April 2009. This new policy will run from 2013 to 2020. Hence, the reinforcement of European Union's energy and climate policy in the decade to come was decided and prepared in 2007-2008. But in the meantime, the economic conditions worldwide and in Europe more particularly have radically changed compared to what they were in 2007-2008 when the package was designed. The European Commission has drafted its proposals for the Climate and Energy Package following the outcomes of an impact assessment based on several modeling tools. These modeling tools were not used for determining the 20-20 in 2020 targets or checking their feasibility - those were political targets decided by the European Council in March 2007. The models served to assess the effects and costs of different allocation methodologies. In its drafting proposals, the Commission projected an annual Gross Domestic Product (GDP) growth of 2.2% on average until 2010 in the EU and a 2.4% growth between 2010 and 2020. But because of the economic crisis, the European Union has on the contrary seen a sharp fall of its GDP in 2009: according to the latest forecast by the International Monetary Fund (IMF), which is quite similar with forecasts from other organizations, such as the European Commission or the OECD, the EU-27 should see its GDP decrease by 4.2% in 2009. Opinions are divided when it comes to the question of when and how fast the economy recovers. The IMF has predicted a rather flat GDP growth in 2010

The Eu is considering the adoption of a tighter emission target, to replace the agreed -20 per cent emission target already agreed on. In this study, we analyze the implications of the proposed -30 per cent EU-wide emission cut from the perspective of the Finnish economy. We use an energy system model to study the technological choices and direct energy and investment costs of the stricter target, and an applied general equilibrium model to analyse its economic implications at industry and macroeconomic levels. We find that the stricter target increases the economic costs roughly proportionally to the abatement effort and consist mostly of the welfare losses of taxation. (orig.)

Advanced Stirling Radioisotope Generator Engineering Unit 2 (ASRG EU2) Final Assembly

Oriti, Salvatore M.

2015-01-01

NASA Glenn Research Center (GRC) has recently completed the assembly of a unique Stirling generator test article for laboratory experimentation. Under the Advanced Stirling Radioisotope Generator (ASRG) flight development contract, NASA GRC initiated a task to design and fabricate a flight-like generator for in-house testing. This test article was given the name ASRG Engineering Unit 2 (EU2) as it was effectively the second engineering unit to be built within the ASRG project. The intent of the test article was to duplicate Lockheed Martin's qualification unit ASRG design as much as possible to enable system-level tests not previously possible at GRC. After the cancellation of the ASRG flight development project, the decision was made to continue the EU2 build, and make use of a portion of the hardware from the flight development project. GRC and Lockheed Martin engineers collaborated to develop assembly procedures, leveraging the valuable knowledge gathered by Lockheed Martin during the ASRG development contract. The ASRG EU2 was then assembled per these procedures at GRC with Lockheed Martin engineers on site. The assembly was completed in August 2014. This paper details the components that were used for the assembly, and the assembly process itself.

The study analyses options for further development of the EU Emissions Trading Scheme (EU-ETS) after 2012. The first analysis focuses on the effects of the EU-ETS on companies, power prices, competitiveness and employment. It is followed by an analysis of overlaps or lacking coverage regarding the climate policies EU-ETS, Eco-Tax (Oekosteuer) resp. Energy Tax, the Renewable Energy Sources Act and the Combined Heat and Powert Act. These instruments are analysed with regards to their coherence. As a next step, the national allocation plans of France, The Netherlands, the United Kingdom and Poland are evaluated and recommendations are developed. Best practice recommendations for further developing the EU-ETS after 2012 both at the European and the national level are developed from the comparison of these European national allocation plans. Finally, design features of certificate systems relevant for international linking of such systems are addressed. In the analysis such design features are identified and approaches for problems potentially arising when certificate systems are linked, are developed. (orig.)

Luminescence properties of different Eu sites in LiMgPO4:Eu2+, Eu3+

Baran, A; Mahlik, S; Grinberg, M; Cai, P; Kim, S I; Seo, H J

2014-01-01

The effect of temperature on the luminescence properties of LiMgPO 4 doped with Eu 3+ and Eu 2+ are presented. Depending on the excitation wavelength, luminescence spectra consist of two distinct broad emission bands peaking at 380 nm and 490 nm related to 4f 6 5d 1  → 4f 7 ( 8 S 7/2 ) luminescence of Eu 2+ and to europium-trapped exciton, respectively, and/or several sharp lines between the 580 nm and 710 nm region, ascribed to the 5 D 0  →  7 F J (J = 0, 1, 2, 3 and 4) transitions in Eu 3+ . To explain all the features of the Eu 2+ and Eu 3+ luminescence we discussed the existence of two different Eu sites substituting for Li + , with short and long distance compensation. The evident effect of increasing the intensity of the Eu 2+ luminescence with increasing temperature was observed. It was considered that the charge compensation mechanism for Eu 3+ and Li + as well as Eu 2+ replacing Li + in the LiMgPO 4 is a long distance compensation that allows for the existence of some of the europium ions either as Eu 3+ at low temperature or as Eu 2+ at high temperature. We concluded that Eu 2+ in the Li + site with long distance compensation yields only 4f 6 5d 1  → 4f 7 luminescence, whereas Eu 2+ in the Li + site with short distance compensation yields 4f 6 5d 1  → 4f 7 luminescence and europium-trapped exciton emission.

Lobbyism and CO2 Trade in the EU

DEFF Research Database (Denmark)

Svendsen, Gert Tinggaard

2002-01-01

Has the EU Directive Proposal on CO2 trade been influenced by lobbyism and can it be improved? After hypothesizing how the EU may be vulnerable to lobbyism and why industrial groups have a strong incentive to lobby for favourable environmental regulation, we turn to empirical evidence concerning...... design. Here, it is possible to measure lobbyism as the difference in proposed design between the Green Paper (before lobbyism) and the final Directive Proposal (after lobbyism). Overall we suggest that this lobbyism affected the design of the EU CO2 market in favour of small-sized and well......-organised industrial interest groups at the expense of the EU tax payers. Most critically, allocation of permits and enforcement issues are to be dealt with at the member state level rather than the supranational level allowing member states to favour their domestic industries. A likely market breakdown means less...

In 2009 the EU decided to reduce greenhouse gas emissions at least by 20% in 2020 compared to 1990 and to supply 20% of energy needs by 2020 from renewable energy sources. This paper uses an energy model coupled with a non-CO 2 greenhouse gas model to assess the range of policy options that were debated to meet both targets. Policy options include trading of renewable targets, carbon trading in power plants and industry and the use of the Clean Development Mechanism to improve cost-efficiency. The models also examined fairness by analysing the distribution of emission reduction in the non-emission trading sector, the distribution of CO 2 allowances in the emission trading sector and the reallocation of renewable targets across Member States. The overall costs of meeting both targets range from 0.4% to 0.6% of GDP in 2020 for the EU as a whole. The redistribution mechanisms employed significantly improve fairness compared to a cost-effective solution. - Research highlights: → Meeting the EU's greenhouse gas and renewable targets costs 0.4-0.6% of GDP. → Trading national targets for renewable energy reduces costs. → Carbon trading in power plants and industry and CDM also lowers costs. → The redistribution mechanisms agreed by the EU significantly improve fairness.

The Euro Zone Crisis and Differentiation in the European Union: a Threat to the Goals of the EU or an Instrument of Managing the Divergence of National Interests?

Directory of Open Access Journals (Sweden)

Vilpišauskas Ramūnas

2014-12-01

Full Text Available This article discusses the institutional evolution of the European Union (EU in reacting to the euro zone crisis and the new forms of differentiation in the EU. It presents and elaborates several arguments. First, despite calls to complete the creation of the “genuine Economic and Monetary Union“ and to make a step towards federal structure of the Union with single currency and single central budget used to react to asymmetric shocks, most decisions actually agreed upon by member states since the start of the crisis can be seen as attempts to avoid exactly such a scenario. Second, although the divide between the “Northern“ and “Southern“ groups of the EU member states seems attractive in its simplicity, it is a gross simplification of the current situation and hides important differences of member state preferences within each of the groupings. Third, it is also too simplistic to see the membership in the euro zone as the main characteristic defining the state of differentiation in the EU. As it is discussed in the text, both euro zone member states and EU countries outside the euro zone participate in different initiatives of integration and show different national preferences. Finally, the text concludes with a formulation of the main policy dilemmas for Lithuania in terms of ongoing process of complex differentiation and taking into account the prospect of joining the euro zone in 2015.

INTEGRATION OF ROMANIAN INSURANCES MARKET IN EU

2015-08-01

Full Text Available One of the most important phenomena of the last decade has been the convergence of the financial services industry, especially the capital and insurance markets. The convergence in the insurance industry was determined by the increased frequency and the severity of catastrophic risks, market inefficiency in the past, and the new technologies in IT and communications. These globally developments can be observed much better at EU level, one of the most integrated areas of the world, which aimed the convergence of financial market, including an important component such as insurance market. As part of the EU, Romania also aims to financial market convergence with the EU countries. The article offers an overview and an analysis of the insurance market in the EU and Romania. Through a wide series of indicators such as: the amount of insurance premiums, degree of penetration, number of employees or number of insurance companies, it will analyze the evolution of this market convergence, as per all EU countries and Romania. It will identify the stage in which the insurance market in Romania is, regarding the requirements of full integration. Finally, there will be identified factors encouraging and particularly those who are impediments to insurance market convergence in Romania.

The Determinants of European Union (EU Foreign Direct Investments in the EU Countries from Central and Eastern Europe During 1994–2012

Directory of Open Access Journals (Sweden)

Tang Donny

2017-03-01

Full Text Available This study examines whether the CEECs’ financial market development can explain the EU FDI in the CEECs during 1994–2012. The higher bank credit flows had a positive effect on the FDI in 2005–2012. This can be attributed to the major banking sector reforms undertaken before the CEECs’ EU accession. Second, the stock market size had a positive effect in 1997–2004. This is due to the fact that the EU membership announcement facilitated deeper stock market integration. Third, the higher country income, in interaction with a higher bank credit flow, had only a small positive effect in 2005–2012. The higher income CEECs have pursued much deeper bank liberalization through large-scale privatization of state-owned banks. Finally, the higher country income, in interaction with a larger stock market size, had a negative effect in 2005–2012. A possible reason for this is that the EU countries have started to divert their new FDI to the non-EU countries.

Green taxes in EU and Denmark; Groenne skatter og afgifter i EU og Danmark

Energy Technology Data Exchange (ETDEWEB)

Dyck-Madsen, S.

2000-12-01

One of the most essential means to reach an increased sustainability in the world is to increase the use of economical means and hereby extend the polluter-pay-principle. The EU-commission, OECD and other governments in the EU-countries recommend an increased use of green taxes. This book takes as its starting point the implementation of a green tax reform, where the taxation is moved from tax on manpower to tax on resource consumption and pollution. Hereby both the environmental effort and the economic development are strengthened. The book briefly examines the different definitions of sustainability and outlines the principles for a green tax reform. The elaboration of green taxes, the reversing entry to environmental aims or to the Exchequer, the relation to the social distribution, the financing of the welfare state, the development of the green taxes in the EU countries, removal of environmentally damaging subsidies and the positive effect of the existing green taxes are subjects treated in the book. Finally the book presents a proposal for some Danish possibilities to increase existing green taxes or to introduce new Danish green taxes. (EHS)

Enhanced flexibility in the EU's 2030 effort sharing agreement: issues and options - Final report

The sectors which are not covered by the European carbon market account for around 60% of the EU's GHG emissions. The European Council has set a target to reduce emissions in these sectors by -30% vs. 2005 levels by 2030. Given the way this target is allocated, there is a risk that EU Member States may fail to achieve their national goals by reducing abatement domestically, while others will undertake too little abatement and avoid needing to begin a low-carbon transition in these sectors. This paper therefore proposes a new design for a European financing mechanism to catalyse action in low-income Member States while ensuring that all Member States comply with the EU targets.

Renewable energies in the EU-Accession States

International Nuclear Information System (INIS)

Reiche, Danyel

2006-01-01

The aim of this article is to discuss obstacles and success conditions for renewable energy sources in the EU-Accession States and to compare them with the framework in the EU-15. Besides the ten states which will join the EU in 2004, Bulgaria and Romania which will probably join in 2007 as well as Turkey are analysed. Most of these countries have had a century-long tradition in the utilisation of RES, primarily in biomass and hydropower. However, the communist regimes were convinced of the superiority of large-scale systems and converted the energy sectors into centralised units. Due to this dominating belief system more decentralised applications such as installations using renewable energies had to close. One crucial driving force for future renewable energy development in the Accession States comes from the stipulations set by the EU. The EU-Directive on the promotion of electricity produced from RES gives the new EU-members targets for their RES-development until 2010. Due to the Directive many Accession States have already begun to pay more attention to the topic and to introduce more systematic policies. Six of the Accession States have introduced minimum tariffs which were one of the main success conditions (besides a stable and sound investment programme as well as favourable background conditions) in the leading wind energy countries Germany and Spain. Beside the external pressure by the EU and other international obligations other driving forces such as the path dependencies in the national energy policies (degree of coal, oil and gas exploitation, nuclear power use, import dependency), the political support schemes for renewable energies, possibilities of obtaining external financial support and the cognitive environment are discussed. Finally similarities and differences between EU-15 and Accession States are worked out

2010-01-01

Eu 3+ -doped SnO 2 nanoparticles with high surface area were generated within the template of the cationic surfactant (cetyltrimethylammonium bromide, CTAB) micelle assembly by surfactant-mediated method from the hydrous tin chloride (SnCl 4 .5H 2 O) and europium chloride (EuCl 3 .6H 2 O). The as-synthesized product was amorphous and transformed into crystalline calcined at 500 o C for 2 h. DSC-TGA, X-ray powder diffraction (XRD), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS) were used to examine the morphology and microstructure of the final products. The results showed that the Eu 3+ -doped SnO 2 nanoparticles with diameter of 3-7 nm were obtained. The influences of the molar ratios of Eu 3+ and CTAB on the room temperature photoluminescence (RTPL) properties of Eu 3+ -doped SnO 2 nanoparticles were investigated. The results showed that the contents of Eu 3+ and CTAB had a great influence on the crystallite sizes and RTPL properties of Eu 3+ :SnO 2 nanoparticles. The maximum of the RTPL intensity can be observed at the molar ratio 5.0% Eu 3+ and 10.0% CTAB.

In spite of the number of studies available in the field and policy documents developed both at the national and the international levels, there is no reliable data available regarding the variation of roles occupied by clinical mentors (CMs) across countries. To describe and compare the CM's role; responsibilities; qualifications; employment requirements and experience in undergraduate nurse education as enacted in 11 European Union (EU) and non- EU countries. A case study design. A panel of expert nurse educators from 11 countries within and outside of the EU (Croatia, Czech Republic, England, Iceland, Ireland, Italy, Poland, Serbia, Slovenia, Spain, and the USA). A questionnaire containing both quantitative and qualitative questions was developed and agreed by the panel using a Nominal Group Technique (NGT); four cycles of data collection and analysis were conducted involving key experts in nursing education in each country. In all countries, there are at least two types of clinical mentorship dedicated to undergraduate nursing students: the first is offered by higher education institutions, and the second is offered by health care providers. Variation was noted in terms of profile, responsibilities and professional requirements to act as a CM; however, the CM role is mainly carried out by registered nurses, and in most countries there are no special requirements in terms of education and experience. Those who act as CMs at the bedside continue to manage their usual caseload, thus the role adds to their work burden. Whilst it is imperative to have respect for the different national traditions in undergraduate nurse education, the globalisation of the nursing workforce and greater opportunities for student mobility during the course of their undergraduate education suggests that in areas such as clinical mentorship, jurisdictions, particularly within the EU, should work towards greater system harmonisation.

Effects of the auto irradiation in KBr:Eu2+ crystals

International Nuclear Information System (INIS)

Perez S, R.; Aceves, R.

2002-01-01

In KCl :Eu 2+ crystals and in KBr :Eu 2+ crystals it has been detected the effect of the auto irradiation with 40 K isotope. In this work, a study of auto irradiation thermoluminescence in KBr :Eu 2+ crystals with different Eu 2+ concentrations and different thermal treatments is presented. The form of the Tl curve shows mainly a sparkle at 110 Centigrade degrees. The sparkle intensity increases linearly in a time interval around 3600 sec. After this time the increase of intensity was slower. In the linear interval, the lukewarm effects are almost scornful. The analysis of results is looked to the relation between the thermoluminescence and the Eu 2+ additions. It is discussed the form of the curve comparing it with the Tl induced by external irradiation sources on this type of materials. Also it is discussed the temporary dependence of the quantity of induced defects. Finally, the Tl intensity results for crystals with and without previous luke warms are compared. (Author)

Impacts of market liberalisation on the EU gas industry

Van Oostvoorn, F.; Boots, M.G.

1999-10-01

The paper presents an analysis of tbc effects of tbc European Union (EU) Gas Directive on the EU natural gas industry in the next ten years. First, it briefly reviews the current driving factors for increasing competition in the EU gas markets. Second, the different directions of implementation of EU Gas Directive are discussed. Finally we give an assessment of impacts of the different directions of implementation of the Gas Directive, thereby focusing on structural changes of the gas industry and the scope for reduction of consumer gas prices. Note that our assessment of the impacts is partly based on an analysis of recent trends in the EU gas market and partly on calculations with a recently developed model of the EU gas market on company level. The paper summarises the main observations of a study conducted by the Netherlands Energy Research Foundation (ECN) last year in the framework of a larger scenario study for the European Committee, Directorate-General 17, in the Shared Analysis Project, 'Economic Foundations for Energy Policy in Europe to 2020' managed by FhG-ISI. For the complete results of the ECN study, see report 'Impacts of Market Liberalisation on the EU Gas Industry', September 1999, forthcoming. Note that the analysis is limited to the gas market and does not include other impacts, i.c. on energy conservation, emissions, etc. 21 refs

EU competences in European energy policy; EU-Kompetenzen einer europaeischen Energiepolitik

Schneider, Almut Madlen

2010-07-01

The author intends to analyze the possible consequences of legal acts in energy policy and to check whether they may serve as competence for an EU energy policy according to the EG or Euratom treaties. She starts by outlining energy-political acts of the EU on the basis first of the former EC treaty and then of the Euratom treaty. These acts cover the issues of nuclear safety and nuclear waste, 'nuclear package' and safeguards monitoring. The next chapter presents the fundamentals of the competence distribution between the EU and its member states. On this basis, the energy-political competences for action of the former EG and Euratom treaties are discussed. This includes operative competences, harmonization competences, material restrictions of national energy policy, and structural instruments for making restrictions on national energy policies. The next chapter presents a critical assessment of the extent of the competence of Article 95 EG (now: Article 114 AEUV) and discusses the role of European law on grants and competition for the functioning of the European energy markets. The 'nuclear package' is reassessed from the view of competence law. Finally, the central new contents of the Lisbon treaty and their consequences for energy law are gone into. The importance of an energy competence title for the energy sector is questioned, and the interdependences between the Lisbon treaty and the Euratom treaty are analyzed. (orig.)

Consistency of policy instruments. How the EU could move to a -30% greenhouse gas reduction target

The report provides options for how to achieve a 30% reduction in greenhouse gas emissions, in the EU, from 1990 to 2020. The EU has agreed a set of goals (objectives) and related instruments for 2020. The most significant objectives are the 20% or 30% reduction of greenhouse gases (all emissions, both within and outside the Emissions Trading System), the 20% improvement of energy efficiency and the 20% of renewable energy use by 2020. The stringency of the instruments used to reach these goals, must be set carefully to ensure overall consistency. Particularly after the economic crisis of 2008/2009, the Climate and Energy Package has to be 'tuned' again to be fully consistent, e.g. fast take up of renewable energy and fewer emissions due to the recession may cause an over-allocation in the EU-ETS.

Optically active centers in Eu implanted, Eu in situ doped GaN, and Eu doped GaN quantum dots

A comparison is presented between Eu implanted and Eu in situ doped GaN thin films showing that two predominant Eu sites are optically active around 620 nm in both types of samples with below and above bandgap excitation. One of these sites, identified as a Ga substitutional site, is common to both types of Eu doped GaN samples despite the difference in the GaN film growth method and in the doping technique. High-resolution photoluminescence (PL) spectra under resonant excitation reveal that in all samples these two host-sensitized sites are in small amount compared to the majority of Eu ions which occupy isolated Ga substitutional sites and thus cannot be excited through the GaN host. The relative concentrations of the two predominant host-sensitized Eu sites are strongly affected by the annealing temperature for Eu implanted samples and by the group III element time opening in the molecular beam epitaxy growth. Red luminescence decay characteristics for the two Eu sites reveal different excitation paths. PL dynamics under above bandgap excitation indicate that Eu ions occupying a Ga substitutional site are either excited directly into the 5 D 0 level or into higher excited levels such as 5 D 1 , while Eu ions sitting in the other site are only directly excited into the 5 D 0 level. These differences are discussed in terms of the spectral overlap between the emission band of a nearby bound exciton and the absorption bands of Eu ions. The study of Eu doped GaN quantum dots reveals the existence of only one type of Eu site under above bandgap excitation, with Eu PL dynamics features similar to Eu ions in Ga substitutional sites

Environmental Tax Policy in Romania in the Context of the EU: Double Dividend Theory

Directory of Open Access Journals (Sweden)

Magdalena Radulescu

2017-10-01

Full Text Available In the last decade, environment protection gained much more significance in designing the economic policies in the European Union (EU countries. There are many economic and policy differences between the European countries, despite of the harmonization process inside the EU area. The path of implementation of the environmental tax reforms in the EU countries differs greatly from one country to another and the effects of such taxation in the economic and environmental areas are manifold. The authors of this paper have agreed to undertake the task of testing the double dividend hypothesis of the environmental taxation in Romania (an energy-intensive country versus the EU area as a whole, using Vector Error Correction Model (VECM techniques and Ordinary Least Squares (OLS estimations. Our findings show that this hypothesis is validated neither in Romania (in the economic growth area nor in the EU area as a whole (in the unemployment area. Therefore, Romania cannot increase the level of the environmental tax for supporting economic growth, but it can grant environmental subsidies for decreasing the emissions and supporting the economic growth. This could be achieved by expanding the tax labor base and by collecting higher budgetary revenues to sustain such environmental subsidies. As far as the EU area is concerned, it is a necessary measure to continue the descending trend for the labor taxation to achieve the goal of improving the employment rate.

The AGREE Enterprise: a decade of advancing clinical practice guidelines.

Science.gov (United States)

Makarski, Julie; Brouwers, Melissa C

2014-08-15

The original AGREE (Appraisal of Guidelines for REsearch and Evaluation) Instrument was published in 2003, and its revision, the AGREE II, in 2009. Together, they filled an important gap in the guideline and quality of care fields. Ten years later, the AGREE Enterprise reflects on a trajectory of projects and international collaboration that have contributed to advancing the science and quality of practice guidelines and the uptake of AGREE/AGREE II. The AGREE Enterprise has undertaken activities to improve the tool and to develop resources to support its use. Since 2003, the uptake and adoption of AGREE by the international community has been swift and broad. A total of 33 language translations of the original AGREE Instrument and the current AGREE II are available and were initiated by the international community. A recent scan of the published literature identified over 600 articles that referenced the AGREE tools. The AGREE tools have been widely received and applied, with several organizations having incorporated the AGREE as part of their formal practice guideline programs. Since its redevelopment in 2010, the AGREE Enterprise website (www.agreetrust.org) continues to experience steady increases in visitors per month and currently has over 10,000 registered users. The AGREE Enterprise has contributed to the advancements of guidelines through research activities and international participation by scientific and user communities. As we enter a new decade, we look forward to ongoing collaborations and contributing to further advancements to improve quality of care and health care systems.

The aim of the EU Drugs Strategy 2013-2020 is to contribute to a reduction in drug demand and drug supply within the EU. The Strategy has so far been implemented by an Action Plan covering the period 2013-2016. This article sets out the findings of an evaluation that assesses the degree of implementation of the Strategy and the Action Plan in terms of outputs and, where possible, impacts. It looks at the extent to which the objectives of the Strategy have been achieved. The evaluation aims to provide evidence to support the European Commission's decision about whether to propose a new Action Plan for the period 2017-2020 and, if so, what changes would be needed compared to the current plan. Through applying a mixed-methods approach, the evaluation examined the effectiveness, efficiency, relevance and coherence of the actions undertaken on the basis of the EU Drugs Strategy and the Action Plan, as well as their EU added value. The evaluation makes 20 recommendations, addressed to the European Commission, Member States, the European Council and other stakeholders. The key recommendation for the Commission is that a new Action Plan should be implemented for the period 2017-2020. This should be an updated version of the current Action Plan, rather than taking a new approach or introducing more new actions.

EU Energy Policy in a Supply-constrained World

International Nuclear Information System (INIS)

De Jong, J.; Van der Linde, C.

2008-10-01

Energy is quickly becoming an issue of integration and disintegration of the EU and will perhaps turn out to be the ultimate litmus test of political and economic unity in the EU, as energy issues are increasingly intertwined with wider security issues on the continent. Very often, economic issues are elevated to the political-strategic level, serving a different agenda than merely contributing to the energy policy agenda of the EU. The challenges to the EU and its member states in the energy sector are many: some issues are part of the wider geopolitical and geo-economic agenda, but some are also the product of the new EU that emerged after the fall of the Berlin Wall. The enlargement with member states that are asymmetrically dependent on oil and gas supplies mainly from Russia has further emphasised the growth of structural energy import dependency. Moreover, the new member states did not have the benefit of introducing the energy 'acquis', i.e. liberalisation, in a period of ample supply and relatively low prices. From 2004 onwards, energy has become tighter and more politicised. It was these developments that also uncovered the calculated risk of the old member states to embark on liberalisation without putting a crisis management policy into place. With the increasing worries about the security of supply and the asymmetric exposure of Eastern Europe to a single supplier, energy security issues also began to dominate the internal policy debates both in energy and in external relations. The new developments require the EU member states to consider how and to what extent their external energy policies should also be merged into a more EU-wide approach, if they can agree on the common risks that need to be averted and the common benefits gained, and if and how a crisis mechanism for fuels other than oil is needed to manage the perceived increased security of supply risks. Moreover, they should also consider the internal market design they set out to implement and

Has accession to the EU affected business cycles?

Directory of Open Access Journals (Sweden)

Panagiotis EVANGELOPOULOS

2013-02-01

Full Text Available This paper undertakes to explain the relationship between EU accession and the length of business cycles, focusing specifically on whether participation in a multinational organization has, or has not, altered the length of the cycle. Employing a sample of nine EU countries (Austria, Denmark, Finland, Greece, Ireland, Portugal, Spain, Sweden and the UK we focused initially on annual data for per capita growth in GDP over a period of 59 years (1950-2008. For each country the sample was divided into two parts, one covering the period preceding accession to the EU and one is covering the accession year and succeeding years. Then, eliminating the background noise with the use of a periodogram, we proceeded to examine their spectral density plots. The results indicated that in the first years following accession, the countries tended to experience shorter cycles than they had previously. In the second phase the cycles were of the same duration as previous cycles. Finally, after a period of some years, the length of the cycles increased, as suggested by the J-shaped curve. This J-shaped growth curve applies for the countries that have joined the EU, strongly suggesting a causal relationship between accession to the EU and these specific characterristics of the curve. We cross-checked with a set of four non-EU member countries (Iceland, Norway, Switzerland and Turkey and found no change in the length of the business cycle in these countries.

151Eu nuclear resonant inelastic scattering of Eu3Pd20Ge6

151 Eu nuclear resonant inelastic scattering of Eu 3 Pd 20 Ge 6 . The Eu partial phonon density of states (DOS) in Eu 3 Pd 20 Ge 6 are investigated using 151 Eu nuclear resonance inelastic scattering (NRIS). 151 Eu NRIS was carried out at BL09XU of SPring-8. Significant temperature dependence was found in the partial phonon DOS. Judging from the valence change at the Eu 4a site and the comparison with the ab initio calculation of Eu 3 Pd 20 Ge 6 , the change of the Eu DOS is caused by the electronic states. On the other hand, significant acoustic contribution was found even at the guest site of the Eu ones. In addition, slower average velocity than transverse sound velocity was obtained by Eu partial phonon DOS. Considering that heat is carried by the acoustic phonon in materials, the present results demonstrate that the moderate thermal insulation in Eu 3 Pd 20 Ge 6 is connected with the observation of slow average sound velocity at the Eu sites.

Full Text Available In recent years, France has oppose d full EU membership for Turkey while Britain has been one of the staunchest supporters of Turkey's EU accession bid. This paper argues that this can be explained by fundamentally different conceptions of the EU in the two countries, based in turn on differences in national concep tions of state and nation. The paper thus analyses recent French and Britis h discourse on the EU and, particularly, on Turkey's accession bid, according to Sjursen's (20 07 framework of three idealised visions of the EU. These are firstly, the EU as a problem-solving entity, secundly as a values-based community based on a common cultural identity and finally as a post-national union underscored by 'universal' rights such as democracy and human rights

Cowan, David T; Norman, Ian J; Coopamah, Vinoda P

Enhanced nurse workforce mobility in the European Union (EU) is seen as a remedy to shortages of nurses in some EU countries and a surplus in others. However, knowledge of differences in competence, culture, skill levels and working practices of nursing staff throughout EU countries is not fully documented because currently no tangible method exists to enable comparison. The European Healthcare Training and Accreditation Network (EHTAN) project intends to address this problem by establishing an assessment and evaluation methodology through the compilation of a skills competency matrix. To this end, subsequent to a review of documentation and literature on nursing competence definition and assessment, two versions of a nursing competence self-assessment questionnaire tool have been developed. The final competence matrix will be translated and disseminated for transnational use and it is hoped that this will inform EU and national policies on the training requirements of nurses and nursing mobility and facilitate the promotion of EU-wide recognition of nursing qualifications.

Full Text Available The aim of this paper is to assess the degree of relative convergence achieved by Albania in relation to the EU during the last decade through a descriptive empirical analysis. The paper is divided into three sections related to real and nominal convergence in the fields of economic performance; trade openness and balance; and monetary convergence, according to the Euro criteria established in the art. 140 (1 of the TFEU and the protocol Nº 13 (price stability, public finances, exchange rate, and long-term interest rates. In order to have a wide perspective about convergence-divergence trends inside and outside the EU, the tendencies followed by Germany and Greece are also mentioned, as paradigmatic cases of divergence within the EU. Finally, a summary table is presented reviewing each of the analysed variables regarding the last decade evolution and the current situation.

Agreeing on expectations

DEFF Research Database (Denmark)

Nielsen, Christian; Bentsen, Martin Juul

Commitment and trust are often mentioned as important aspects of creating a perception of reliability between counterparts. In the context of university-industry collaborations (UICs), agreeing on ambitions and expectations are adamant to achieving outcomes that are equally valuable to all parties...... involved. Despite this, our initial probing indicated that such covenants rarely exist. As such, this paper draws on project management theory and proposes the possibility of structuring assessments of potential partners before university-industry collaborations are brought to life. Our analysis suggests...

With regard to phosphor thermometry, the materials Y{sub 3}Al{sub 5}O{sub 12}:Eu (YAG:Eu) and YAlO{sub 3}:Eu (YAP:Eu) were synthesised and characterised in order to substitute the commonly used thermographic phosphor Y{sub 2}O{sub 3}:Eu, whose temperature sensitive luminescence lifetime exhibits a strong and most often undesirable cross-sensitivity to the oxygen concentration of the surrounding gas phase. The synthesis is outlined in detail and the crystallographic structure was characterised by X-ray diffraction. In a second step, the luminescence properties following pulsed UV laser excitation were determined. In this context, the emission spectra and the temperature lifetime characteristics were monitored. For Y{sub 3}Al{sub 5}O{sub 12}:Eu and YAlO{sub 3}:Eu, temperature sensitive ranges of 1000 K–1470 K and 850 K–1300 K were identified. Contrary to Y{sub 2}O{sub 3}:Eu, both materials do show much lower cross-sensitivities to the oxygen concentration of the surrounding gas phase. - Highlights: ► Y{sub 3}Al{sub 5}O{sub 12}:Eu and YAlO{sub 3}:Eu were synthesised and characterised. ► The synthesis is outlined and the crystallographic structure was characterised. ► Emission spectra and the temperature lifetime characteristics were monitored. ► Compared to Y{sub 2}O{sub 3}:Eu lower sensitivities to the oxyg. conc. of the gas phase emerged.

We aimed to evaluate the effect of health literacy on agreement for bariatric surgery among morbidly obese patients. The data of 242 morbidly obese patients (body mass index-BMI ≥ 40 kg/m 2 ) were evaluated in a cross-sectional case-control pattern. The patients were classified into two groups as those who were attending the clinic for the purpose of receiving bariatric surgery (n = 138) and those who did not (n = 104). The Turkish version of the European Health Literacy Survey Questionnaire (HLS-EU-Q47), consisting of 47 questions, was used for the health literacy evaluation. It was seen that patients who accepted bariatric surgery were younger and had higher weight and BMI values (p bariatric surgery and 26.04 (8.33:46.88) in the group who did not agree to bariatric surgery, and a statistically significant difference was determined between the two groups (p bariatric surgery and 45.2% of the group who did not (p  25-33) (respectively, 36.2%, 37.5%, p = 0.840). A sufficient level (> 33-42) and a perfect level were higher in the group who agreed to bariatric surgery (respectively, 42.8%, 18.1%, p bariatric surgery in morbidly obese patients. The higher the health literacy level, the more the agreement to bariatric surgery increased.

Tremonti, M.; Breedvelt, L.; Padovan, G.; Bosio, S.; Corsini, M.

2008-01-01

In the light of the EuP Directive (2005/32/EC), producers of Energy using Product (EuP) are obliged to initiate eco design activities. Fourteen product groups are currently under study, one being the preparatory EC study Eco Boiler, and will result in a EuP Working Plan. The LCA of a condensing boiler, commissionated by an Italian SME in the Lombardy Region, has been conducted to support its environmental strategy and communication, to start implementing eco design activities and to anticipate implications to the EuP Directive. In line with the Eco Boiler study, no detailed LCA has been applied, instead a simplified LCA proves to be a strategic tool to support the company environmental objectives. Specifically, the condensing boiler (the option with the best environmental performance and the lowest life cycle costs for the final consumer) has been internally compared to other boilers, resulting in useful eco design recommendations

In this article I study the long-term evolution of the main categories of expenditure of the European Union (EU) budget (1984-2011). The aim is to assess the extent to which the EU is affected by a structural form of policy inertia, and to investigate the general pattern of policy stability...... and change in the EU in light of the two models of policy dynamics currently existing in the literature: the incrementalist model and the punctuated equilibrium model. The analysis of long series of original data extracted from the EU budget shows that EU policies do not evolve following an incrementalist...

A discrete γ-ray ransition with an energy of 3360.6 keV deexciting the second lowest SD state in 143 Eu has been discovered. It carries 3.2 % of the full intensity of the band and feeds into a nearly spherical state which is above the I = 35/2 (+) , E x =4947 keV level. The exact placement of the single-step link is, however, not established due to the specially complicated level scheme in the region of interest. The energy of the single-step link agrees well with the previously determined two-step links. (orig.)

Developing 2050 decarbonization strategies in the EU: Insights on good practice from national experiences

International Nuclear Information System (INIS)

Sartor, Oliver; Donat, Lena; Duwe, Matthias; Umpfenbach, Katharina

2017-01-01

There is increasing recognition that achieving deep cuts to GHG emissions requires a close link between long term strategic planning and short term policy action. Long term decarbonization strategies are important at a technical level, because they can help countries to identify concrete and feasible pathways to decarbonization, based on their national particularities, and then to determine their implications for immediate policies and measures. They can also serve an important social and political function, by facilitating a concrete and analytically based discussion between national stakeholders about what long-term decarbonization implies. Article 4.19 called on Parties to the Paris Agreement to develop long term low emissions development strategies, and decision 1/CP21 invites Parties to present them ahead of 2020. To implement this requirement across all 28 EU countries, the EU is in the process of agreeing minimum requirements and guidelines under a draft new governance regulation for the EU's Energy Union project. Unfortunately, early drafts of this document contain too little detail on what these strategies should include, or how member states should go about developing them. This is a concern, not only for the quality of climate governance in the EU, but also in terms of the potentially negative signal the EU may send under the Paris process, if many of its member states are incapable of producing robust and credible 2050 decarbonization strategies. A small number of EU member states have already developed their own 2050 decarbonization strategies and plans. This study - which was jointly undertaken by IDDRI in France and Ecologic in Germany - highlights some important lessons that can be learned from recent experiences with 2050 decarbonization strategies in selected EU countries. It builds on experiences in a small group of EU member states to highlight some examples of good practice when it comes to long term decarbonization strategy development. If the

The CO2MPARE model supports national and regional authorities in making balanced decisions for their investment portfolio under their regional development programmes, in particular under their Operational Programmes of EU Regional Policy. The EU's climate objectives require that investments across the EU are channeled towards low-carbon development. The carbon impacts of investments should therefore be seriously considered in the decision making process of regional development programmes. The CO2MPARE model informs national and regional authorities on the impacts that the investments under various Operational Programmes can have in terms of CO2 emissions. Knowing which investments lead either to additional emissions or rather to emission reductions, and what the overall impact of a programme is, represents the first step towards investment decisions that have decarbonisation co-benefits. CO2MPARE estimates the combined carbon impact of all activities that take place under a programme, and provides insights into the relative contributions of the different themes. Through its high aggregation level, it allows comparison of investment scenarios rather than individual projects. As such, it aims to support informed decisions on investment strategies rather than project investment decisions. In doing so, it also helps to build and develop a 'carbon culture' within the authorities directly or indirectly in charge of managing Regional Policy Operational Programmes. The model is primarily aimed at Operational Programmes co-financed by the European Regional Development Fund (ERDF)

SrF 2 :Eu nanophosphors were successfully synthesized by the hydrothermal method. The structure of the nanophosphors was investigated with x-ray diffraction. The average crystallite size calculated using the Scherrer equation was in the range of 7.0 nm. The photoluminescence of Eu doped as-prepared SrF 2 nanophosphors were studied using different excitation sources. The samples showed emission from both the Eu oxidation states, Eu 2+ and Eu 3+ . At low Eu concentrations the emission from Eu 2+ centered at 416 nm was more dominant. While the narrow band of Eu 3+ emission intensity increased with an increase in the Eu concentration. High resolution x-ray photoelectron spectroscopy results indicated that the Eu was indeed in both Eu 2+ and Eu 3+ valance states. The presence of Eu 2+ and Eu 3+ in the system largely enhanced the response of the Eu 3+ under ultraviolet excitation. The time of flight-secondary ion mass spectrometry results suggested that the energy transfer between two ions was likely to occur. The relative photoluminescence intensity of the Eu 2+ rapidly decreased with an increasing laser beam irradiating time. This result would make the current Eu 2+ doped SrF 2 samples unsuitable candidates for several applications, such as white light-emitting diodes and wavelength conversion films for silicon photovoltaic cells. - Highlights: • SrF 2 : Eu nanophosphors were successfully synthesised (hydrothermal technique). • PL and XPS results showed enhanced absorption response of Eu 3+ UV excitation. • Eu concentrations more than 5 mol% improved fluorescence emission. • TOF-SIMS results suggested that the energy transfer from Eu 2+ to Eu 3+ is dominant

The superconducting Satellite Tokamak machine “JT-60SA” under construction in Naka Fusion Institute is an international collaborative project between Japan Atomic Energy Agency (JAEA) as the Implementing Agency (IA) of Japan (JA) and Fusion for Energy (F4E) as the IA of Europe (EU). The contributions for this project are based on the supply of components, and thus European manufacturer shall conduct the installation, commissioning and tests on Naka site under the general supervision by F4E via the designated institute in each EU nation. This means that JAEA had an issue to manage the works by European workers and their safety although there is no direct contract. This report describes the approaches for the work and safety managements, which were agreed with EU after the negotiation, and the completed on-site works for Quench Protection Circuits (QPC) as the first experience for EU in JT-60SA project.

Zhu, Chaofeng; Wu, Dongqun; Zhang, Yanfei; Zhang, Meimei; Yue, Yuanzheng

2015-01-01

Highlights: • Eu doped oxyfluoride glasses for LED applications are studied. • Conversion of Eu 3+ to Eu 2+ is realized in the glasses prepared in air atmosphere. • CaF 2 crystals formed during melt cooling enhance the conversion of Eu 3+ to Eu 2+ . • Content of CaF 2 crystals can be controlled by adjusting base glass compositions. - Abstract: Europium doped oxyfluoride glasses were prepared by the melt quenching method for the light emitting diodes applications. The optical and structural properties of these glasses were studied by means of photoluminescence spectra, Commission Internationale de L’Eclairage chromaticity coordinates, X-ray diffraction, and Fourier transform infrared spectra. We find that the spontaneous reduction of Eu 3+ to Eu 2+ is realized by Eu 3+ ions occupying the sites of Ca 2+ in the glasses prepared in air atmosphere. The Eu 3+ to Eu 2+ conversion efficiency, optical performances and structure of the glasses strongly depend on the base glass compositions. For certain base glass compositions, CaF 2 crystals can form during the melt cooling process, and thereby enhance the conversion from Eu 3+ to Eu 2+ . The formation of CaF 2 crystals can be suppressed by adding CaO, Al 2 O 3 and B 2 O 3 , but enhanced by adding Na 2 O and K 2 O in glass compositions. Finally, we propose a mechanism to explain how the glass structure affects the reduction of Eu ions as well as optical properties of the glasses

Total neutron cross-section measurements have been carried out for natural Eu and its stable isotopes in the energy range from 3 meV to 1 eV. The measurements were performed using two time-of-flight spectrometers installed in front of two of the horizontal channels of the ET-RR-1 reactor. The following results have been obtained: sigmasub(a) ( 151 Eu) = (9180 +- 150) b at 0.0253 eV, sigmasub(s) ( 153 Eu) = (375 +- 20) b at 0.0253 eV, sigmasub(d) (Eu) = (4600 +- 120) b at 0.0253 eV. The contribution of the resonance to the total neutron cross-sections, in the thermal region, was calculated using the single-level Breit-Wigner formula. (orig.)

An overview of current research on EU ETS: Evidence from its operating mechanism and economic effect

International Nuclear Information System (INIS)

Zhang, Yue-Jun; Wei, Yi-Ming

2010-01-01

The European Union Emissions Trading Scheme (EU ETS) is supposed to be an important mechanism for addressing climate change. Up to now, the theoretical foundation of EU ETS has been widely acknowledged, but empirical research on its current situation has only been published recently or is forthcoming. Therefore, this paper is aimed to summarize the main arguments of empirical studies on the EU ETS, in terms of two aspects, i.e., the operating mechanism and economic effect of the EU ETS, which are two crucial topics and have been attached much attention. Based on the shortcomings of current research and future requirements of the EU ETS evolution, finally, we also present some further directions of the EU ETS research. Overall, the research overview here may be helpful to recognize the features of the EU ETS and its effect on others. (author)

This publication shows that the environmental ministers of the EU member states are largely agreed that a new generation of green legislation with dynamic standards is needed in order to create strong incentives for resource-efficient innovation. The German Federal Government has recognised the potential of this approach and is making a political drive for the introduction of a top-runner promotion scheme at EU level. A scheme of the same kind has also been incorporated in Germany's energy efficiency action plan. The top runner promotion scheme is a system of requirements and incentives for the promotion of the best and most efficient products on the market. It can also serve as a guiding model for product-related environmental protection in Germany. In its general considerations of the interaction between community law and national law in the implementation of the top runner promotion scheme on the basis of the Ecodesign Directive and in a special analysis based on the example of boilers and small-scale firing installations the present study shows that there is a trend of steady curtailment of the legislator's scope of influence. If any national scope for product-related regulation does still exist, then only in niches, but not in a manner that would permit the legal implementation of broad concepts.

Synthesis and tunable luminescent properties of Eu-doped Ca2NaSiO4F – Coexistence of the Eu2+ and Eu3+ centers

Directory of Open Access Journals (Sweden)

Mubiao Xie

Full Text Available Novel phosphors Ca2NaSiO4F:Eu were synthesized successfully by the conventional solid-state method in CO atmosphere, and their spectroscopic properties in UV−vis region were investigated. The photoluminescence properties show that Eu3+ ions were partially reduced to Eu2+ in Ca2NaSiO4F. As a result of radiation and re-absorption energy transfer from Eu2+ to Eu3+, both Eu2+ bluish-green emission at around 520 nm and Eu3+ red emission are observed in the emission spectra under the n-UV light excitation. Furthermore, the ratio between Eu2+ and Eu3+ emissions varies with increasing content of overall Eu. Because relative intensity of the red component from Eu3+ became systematically stronger, white light emission can be realized by combining the emission of Eu2+ and Eu3+ in a single host lattice under n-UV light excitation. These results indicate that the Ca2NaSiO4F:Eu phosphors have potential applications as a n-UV convertible phosphor for light-emitting diodes.

Highlights: •Persistent phosphor SrAl{sub 2}O{sub 4}:Eu{sup 2+} was synthesized and studied. •Ab initio calculations of its electronic properties were performed. •Lowest position of the Eu 4f states in the band gap was determined. •Position of the Eu 4f states agrees with the charge transfer transition. -- Abstract: A stoichiometric micro-sized powder SrAl{sub 2}O{sub 4}:Eu{sup 2+} was synthesized by traditional solid state reaction at 1250 °C. Low-temperature spectroscopic measurements revealed two luminescence bands at 450 nm and 512 nm; their origin was discussed. Theoretical calculations of the structural and optical properties of SrAl{sub 2}O{sub 4}:Eu{sup 2+} in the framework of the density functional theory (DFT) were carried out; the obtained results were compared with the corresponding experimental data. For the first time, the position of the lowest 4f states of Eu in the host’s band gap was calculated for both available Sr positions to be at about 4.5–5 eV above the top of the valence band. Reliability of this result is confirmed by good agreement with the experimental value of the O(2p)–Eu(4f) charge transfer energy, which is equal to about 4.9 eV.

The EU is one of the most advanced places of petroleum substituting energy development. The EU is highly aware of environmental issues. For the COP3 held at Kyoto in December 1997, The EU gave more severe regulation of CO2 emission than the other advanced countries. The EU takes efforts in the development and introduction of energy effective for global environmental protection. In addition, research and development of geothermal, biomass and wave force energy are actively promoted in this place. Energy situations in this place are significant for predicting and analyzing the future trends of energy development and consumption in the other countries. Firstly, this report looks back toward energy demand held in check to a head at the beginning of the 1990`s. Secondly, supply of energy and cover of energy trend are described for recent years from the point of view. Thirdly, competitiveness of energy in EU countries are discussed from a position of energy density. Fourthly, circumstances about environmental issues are considered. Fifthly, the world market of energy is also considered. Finally, development of new energy and a trend of introduction with a sample of Sweden are introduced. 13 refs., 15 figs., 28 tabs.

How to trigger low carbon technologies by EU targets for 2030? An assessment of technology needs

Energy Technology Data Exchange (ETDEWEB)

Groenenberg, H.; Van Breevoort, P.; Janeiro, L.; Winkel, T.

2013-04-15

The current EU framework for energy and climate policies up to 2020 consists of three headline targets: 20% reduction of GHG emissions compared to 2005, a 20% share of renewable energy in final energy consumption, and 20% primary energy savings compared to baseline developments. While progress on these 2020 targets is mixed, discussions in the EU about climate and energy policies and targets for the period after 2020 have started. Given the long cycles associated to energy and climate investments, agreement on a clear longer-term policy framework is critical to improve visibility for investors and avoid lock-in effects in inefficient or polluting technologies. Therefore, the European Commission published a Communication on 6 June 2012 on the need for a long term policy framework for renewable energy, and a Green Paper on the 2030 climate and energy policy framework on 27 March 2013. Against this background, the Dutch Ministries of Infrastructure and Environment and the Ministry of Economic Affairs requested PBL to create input for the European debate on climate targets and policies until and beyond 2030. Ecofys supported PBL by addressing the following two questions: (1) What steps are needed for selected key technology groups to achieve long term GHG emission reductions and what climate and energy policies are likely to trigger these steps?; and (2) What are the pros and cons of a 2030 policy framework with (a) a GHG reduction target only, and (b) targets for GHG reduction, renewable energy, and energy efficiency? The focus of the first question was on four technology groups, namely (1) energy efficiency in the built environment, notably for heat; (2) solar PV and wind energy; (3) advanced biofuels; (4) CO2 carbon capture and storage (CCS). An analysis of the steps needed for the deployment of the full GHG mitigation potential of the discussed technology groups shows that this will largely depend on the adoption of a wide range of policy instruments by EU Member

SrF{sub 2}:Eu nanophosphors were successfully synthesized by the hydrothermal method. The structure of the nanophosphors was investigated with x-ray diffraction. The average crystallite size calculated using the Scherrer equation was in the range of 7.0 nm. The photoluminescence of Eu doped as-prepared SrF{sub 2} nanophosphors were studied using different excitation sources. The samples showed emission from both the Eu oxidation states, Eu{sup 2+} and Eu{sup 3+}. At low Eu concentrations the emission from Eu{sup 2+} centered at 416 nm was more dominant. While the narrow band of Eu{sup 3+} emission intensity increased with an increase in the Eu concentration. High resolution x-ray photoelectron spectroscopy results indicated that the Eu was indeed in both Eu{sup 2+} and Eu{sup 3+} valance states. The presence of Eu{sup 2+} and Eu{sup 3+} in the system largely enhanced the response of the Eu{sup 3+} under ultraviolet excitation. The time of flight-secondary ion mass spectrometry results suggested that the energy transfer between two ions was likely to occur. The relative photoluminescence intensity of the Eu{sup 2+} rapidly decreased with an increasing laser beam irradiating time. This result would make the current Eu{sup 2+} doped SrF{sub 2} samples unsuitable candidates for several applications, such as white light-emitting diodes and wavelength conversion films for silicon photovoltaic cells. - Highlights: • SrF{sub 2}: Eu nanophosphors were successfully synthesised (hydrothermal technique). • PL and XPS results showed enhanced absorption response of Eu{sup 3+} UV excitation. • Eu concentrations more than 5 mol% improved fluorescence emission. • TOF-SIMS results suggested that the energy transfer from Eu{sup 2+} to Eu{sup 3+} is dominant.

The Interface Between EU Competition Law and Standard Essential Patents

In this paper the recent ECJ judgment in Huawei is discussed in light of the earlier case law from the EU and the US. The Huawei case has been long awaited and many in academia hoped that it would finally deliver answers to if, when and on what terms access to so-called Standard Essential Patents...... would be granted under EU antitrust law. However, the question is whether Huawei is that case. On the contrary, it seems that the ECJ ruling gives room for speculation even in reference to core issues, some of which are dealt with in this paper....

Enlarging the EU's internal energy market: Why would third countries accept EU rule export?

International Nuclear Information System (INIS)

Prange-Gstoehl, Heiko

2009-01-01

Why would countries without a membership perspective seek integration into the EU's internal energy market? One major element of the EU's external energy policy is the export of EU energy norms and regulations to neighbourhood countries and beyond. A core legal instrument the EU uses in this context is the Energy Community Treaty (ECT). The ECT goes both geographically and regarding its depth significantly beyond neighbourhood or association policies, addressing potentially also countries in the 'far neighbourhood' and aiming at the creation of a Single Market for energy with these countries. While, however, EU candidate countries are obliged to adopt the 'acquis' before accessing the EU and therefore comply to EU rules already before they enter the Club, I argue that countries with no or only a vague membership perspective - i.e. countries where the EU cannot apply the 'conditionality' - approach (e.g., ENP countries)-aim at deeper integration with the EU because they are either eager to demonstrate their capability and potential to become part of the Club, they seek greater independence from a regional hegemon or they envisage significant economic gains as common norms, rules and standards are likely to increase economic exchange with the EU.

Total neutron cross-section measurements have been carried out for natural Eu and its stable isotopes in the energy range from 3 meV to 1 eV. The measurements were performed using two time-of-flight spectrometers installed in front of two of the horizontal channels of the ET-RR-1 reactor. The following results have been obtained: sigmasub(a) (/sup 151/Eu) = (9180 +- 150) b at 0.0253 eV, sigmasub(s) (/sup 153/Eu) = (375 +- 20) b at 0.0253 eV, sigmasub(d) (Eu) = (4600 +- 120) b at 0.0253 eV. The contribution of the resonance to the total neutron cross-sections, in the thermal region, was calculated using the single-level Breit-Wigner formula.

Russian energy in the EU market: Bolstered institutionsand their effects

International Nuclear Information System (INIS)

Romanova, Tatiana

2014-01-01

The article examines institutional changes in EU–Russian energy relations since 2000. The article explores the ability of transformed institutions to limit the politicisation of energy and to reconcile the EU competitive-market approach with Russian state capitalism. More specifically, the article focuses on changes in intergovernmental, transgovernmental and transnational interactions. The article demonstrates that the gradual strengthening of transgovernmental and transnational institutions has inhibited the politicisation of energy relations and facilitated regulative cooperation between the EU and Russia. However, the potential of shared institutions is constrained by internal institutions on both sides. In Russia, these obstacles are insufficient top-down delegation of responsibilities in the government and its great power aspirations. In the EU, key barriers include inter-institutional rivalries, the EU’s propensity to impose its legislation on external partners and the integration of energy policy with foreign policy. The article presents several policy implications. First, it is futile to institutionally impose the regulative paradigm of one partner on the other; rather, mutual dialogue is needed. Thus, institutions should be structured appropriately. Second, current depoliticisation will require the involvement of not only the EU and Russia but also transit countries, such as Ukraine. Third, transgovernmental and transnational cooperation should be nurtured because this is a useful channel for both information exchange and a regulative convergence of policy implementing mechanisms. Finally, this incremental regulative convergence is the only option available today for the EU and Russia; this is also a way to further depoliticise energy relations. - Highlights: • EU and Russia developed transgovernmental and transnational energy institutions. • It allowed them to face energy challenges: depoliticisation and market construction. • Internal EU and

2008-01-01

The EuSe nanoparticles were prepared by the thermal reduction of Europium nitrate with new organic selenium compound, tetraphenylphosphonium diphenylphosphinediselenide (PPh 4 )(Se 2 P(C 6 H 5 ) 2 ), for the first time. EuSe nanoparticles were identified by the X-ray diffraction (XRD), the transmission electron microscope (TEM) and the energy dispersive X-ray spectroscopy (EDX) measurements. The average size of the EuSe nanoparticles was found to be 19 nm. The energy gap in EuSe nanoparticles of 19 nm was estimated by edge of absorption band, giving the energy gap of 1.86 eV

Development of Romanian Nuclear Power Program implications for future's EU enlargement

Energy and transport are two areas for which relations with third countries are crucial. Transport is of course essential in order to ensure smooth movements of people and economic operators within the EU but also with the outside world. Its importance becomes even more apparent in a period characterised by globalization. If modes of transport are the arteries of our society, then energy is the blood. The Green Paper on the security of EU energy supply issued by the Commission shows that whereas the EU economy is energy-intensive, Community energy resources are limited. Consequently, the EU is dependent on external sources of energy, a situation which will not change with the forthcoming enlargement. Hence, most of the EU's external relations include an important chapter on energy. The instrument for applying Romania's pre-accession strategy is the National Programme for Accession (NPAR). I focused on the current situation, short and medium term priorities of the Nuclear Energy as part of the Energy Chapter of the NPAR. In spite of the Romanian Authorities' strong commitment for the completion of Unit2, obtaining the EURATOM loan, for which Societatea Nationala Nuclearelectrica S.A. applied to the European Commission in 1999, remained a critical component of the overall financing requirements of this project. The National Strategy for the Development of the Energy Sector on Medium Term 2001- 2004, as part of our national economic strategy, concludes that on a least-cost basis and considering programs for improving energy efficiency, it is necessary to have Cernavoda Unit 2 in operation by 2006. Finally, are presented the benefits for Romania, as a country involved in the process of European Integration, with a view to obtaining the EURATOM loan and finalizing Cernavoda NPP - Unit2.(author)

Ni/EuS multilayers with excellent multilayer sequencing are deposited via e-beam evaporation on the native oxide of Si(100) wafers at 4 × 10{sup −9} millibars. The samples have very small surface and interface roughness and show sharp interfaces. Ni layers are nanocrystalline 4–8 nm thick and EuS layers are 2–4 nm thick and are either amorphous or nanocrystalline. Unlike for Co/EuS multilayers, all Eu ions are in divalent (ferromagnetic) state. We show a direct antiferromagnetic coupling between EuS and Ni layers. At room temperature, the EuS layers are spin-polarized due to the proximity of Ni. Therefore, Ni/EuS is a candidate for room-temperature spintronics applications.

Thermodynamic assessment of EuBr2 unary and LiBr-EuBr2 and NaBr-EuBr2 binary systems

International Nuclear Information System (INIS)

Gong, Weiping; Gaune-Escard, Marcelle

2009-01-01

As a basis for the design and development of molten salt mixtures, thermodynamic calculations of the phase diagrams and thermodynamic properties were carried out on the EuBr 2 unary and LiBr-EuBr 2 and NaBr-EuBr 2 binary systems over a wide temperature and composition range, respectively. The Gibbs energy of EuBr 2 was evaluated using an independent polynomial to fit the experimental heat capacity, the thermodynamic parameters for each phase in the LiBr-EuBr 2 and NaBr-EuBr 2 systems were optimized by using available experimental information on phase diagrams. A regular substitutional solution model for the liquid phase and Neumann-Kopp rule for the stoichiometric compound LiEu 2 Br 5 were adopted to reproduce the experimental data with reasonable excess Gibbs energy. Comparisons between the calculated phase diagrams and thermodynamic quantities show that all reliable experimental information is satisfactorily accounted for by the present thermodynamic description. Some thermodynamic properties were predicted to check the suitability of the present calculation.

We look at migration flows from 8 Central and Eastern European Countries (CEECs) to 5 Nordic countries over the years 1985 - 2005 and we can exploit a natural experiment that arose from the fact that while Sweden opened its labour market from the day one of the 2004 EU enlargement, the other Nordic...... countries chose a transition period in relation to the "new" EU members. We employ a differences-in-differences estimator in our analysis. The results show that the estimated effect of the opening of Swedish labour market in 2004 on migration is insignificantly different from zero. Further, we...... are interested in the overall effect of the "EU entry" on migration. Therefore we look at migration flows from CEECs during the first round EU enlargement towards CEECs in 2004 and compare them with migration flows from Bulgaria and Romania. We again used a DD estimator in our analysis. The estimated effect...

EuO and Gd-doped EuO thin films. Epitaxial growth and properties

International Nuclear Information System (INIS)

Sutarto, Ronny

2009-01-01

Europium oxide (EuO) based materials exhibit a wealth of spectacular phenomena, including half-metallic ferromagnetism, metal-insulator transition, colossal magneto-resistance, large magneto-optical Kerr effect, tunable ferromagnetic ordering temperatures, and large and long-lived photo-induced conductivity. These extraordinary properties make EuO an ideal candidate for implementation in device applications, in particular, for spintronics. Most of the work in the past has been carried out on bulk EuO, but for device applications it is preferred to have the EuO in thin lm form. A urry of studies have therefore emerged in the last decade in order to explore a wide variety of preparation routes and to investigate the properties of the resulting EuO thin films. A recent highlight is the demonstration that doped EuO films can be fabricated on Si and GaN, thereby exhibiting the expected spin-polarized transport effects. Nevertheless, it is still far from a trivial task to prepare EuO thin films with well de ned properties. For bulk EuO, it is already known that stoichiometry is the key issue, and that the presence of small amounts of defects or impurities quickly lead to very large deviations of the material properties. In fact, to make bulk EuO to be stoichiometric one needs temperatures as high as 1800 C. It is obvious that such high temperatures are not compatible with device engineering processes. The preparation of thin films must therefore involve much lower temperatures, preferably not higher than 400-500 C. The consequences are very dear. It turned out that many of the recent studies on EuO thin films are suffering from sample quality problems, due to the presence of, e.g., trivalent Eu species (Eu 3 O 4 , Eu 2 O 3 ), oxygen vacancies, or even Eu metal clusters. Controlled doping of the EuO with trivalent rare-earth ions is also not trivial, since most often even the actual doping concentrations were not known. In fact, one could also question in this respect the

Wier, Mette; Andersen, Johnny M.; Jensen, Joergen D.; Jensen, Thomas C.

2002-01-01

The Agenda 2000 reform, agreed on by the EU government leaders in the spring of 1999, implies considerable changes in EU agricultural policy. The reform involves both reductions in price support and compensations in the form of hectare and animal support. The Agenda 2000 reform may have considerable environmental and economic effects, and in this article we assess these effects. Within an integrated model system, we calculate environmental effects (changes in nitrogen loading in the terrestrial environment and the Danish marine waters, changes in oxygen concentrations in the inner Danish marine waters, and changes in emissions of the greenhouse gases (methane and nitrous oxide)), as well as economic effects (effects on private consumption, GDP, the balance of payments, and employment). The results indicate that the Agenda 2000 reform has significant economic costs but almost no effects on the environment - either positive or negative

EU-MOLDOVA TRADE RELATIONS: COMPETITIVE ADVANTAGES OF MOLDOVAN INDUSTRIES ON THE SINGLE MARKET

Full Text Available Engaging on the long road of implementing the Deep and Comprehensive Free Trade Area with the EU in 2010, Moldova is now closer than ever to being included in the most privileged category of the Eastern neighbouring countries - those who have chosen to deepen the European economic integration. The Vilnius Summit in November 2013 has reinforced the ‘more for more’ principle for both Moldova and Georgia by emphasizing, at the same time, the role of reactive measures and financial aid in counterbalancing aggressive trade barriers from non-EU states. Not only has Moldova proved to efficiently capitalize the provisions of the ATP agreement since 2008, but it has also consequently received more support from the EU in boosting exports to the single market. The wine industry was the first to benefit from the free-trade regime, as for the EU decision of eliminating quotas from the beginning of 2014. Nonetheless, the progressive liberalisation of trade flows between Moldova and the EU would finally oppose two asymmetric partners. Consequently, Moldova is facing the challenge of asserting its value on the EU market, by yet not undermining the relevance of other important trading partners nearby.

Full Text Available Eu3+ doped bulk monoliths and thin films were obtained by sol-gel methods in the ZrO2, SiO2 and SiO2-TiO2 systems. Eu3+ 5D0 ® 7FJ emission and decay time characteristics were measured during the entire experimental preparation route from the initial sol to the final xerogels. The crystalline phases identified were tetragonal ZrO2 and mixtures of rutile and anatase TiO2 at high temperature treatments in bulk samples. Good quality thin films were obtained for all systems by dip-coating optical glasses (Schott BK270. The same spectroscopic features were observed either for the bulk monoliths or the films. By appropriate heat treatments under H2 atmosphere Eu2+ containing samples could be obtained in the SiO2-TiO2 system.

Autism in Preschoolers: Does Individual Clinician’s First Visit Diagnosis Agree with Final Comprehensive Diagnosis?

Gunilla Westman Andersson

2013-01-01

Full Text Available Comprehensive clinical diagnosis based on all available information is considered the “gold standard” in autism spectrum disorders (ASD. We examined agreement across independent assessments (clinical judgment of 34 young children (age 24–46 months with suspected ASD, assessed by a multidisciplinary team, and final comprehensive clinical diagnosis. Agreement across settings and between each clinician’s assessment and final diagnosis was moderate. The poorest fit was found at assessment in connection with psychological evaluation and the best with preschool observation and parent interview. Some individual clinicians had good and others had poor fit with final diagnosis. Disagreement across assessments was pronounced for girls. The findings suggest that multidisciplinary assessments remain important and that comprehensive clinical diagnosis should still be regarded as the gold standard in ASD.

The AGREE II instrument is the most commonly used guideline appraisal tool. It includes 23 appraisal criteria (items) organized within six domains. AGREE II also includes two overall assessments (overall guideline quality, recommendation for use). Our aim was to investigate how strongly the 23 AGREE II items influence the two overall assessments. An online survey of authors of publications on guideline appraisals with AGREE II and guideline users from a German scientific network was conducted between 10th February 2015 and 30th March 2015. Participants were asked to rate the influence of the AGREE II items on a Likert scale (0 = no influence to 5 = very strong influence). The frequencies of responses and their dispersion were presented descriptively. Fifty-eight of the 376 persons contacted (15.4%) participated in the survey and the data of the 51 respondents with prior knowledge of AGREE II were analysed. Items 7-12 of Domain 3 (rigour of development) and both items of Domain 6 (editorial independence) had the strongest influence on the two overall assessments. In addition, Items 15-17 (clarity of presentation) had a strong influence on the recommendation for use. Great variations were shown for the other items. The main limitation of the survey is the low response rate. In guideline appraisals using AGREE II, items representing rigour of guideline development and editorial independence seem to have the strongest influence on the two overall assessments. In order to ensure a transparent approach to reaching the overall assessments, we suggest the inclusion of a recommendation in the AGREE II user manual on how to consider item and domain scores. For instance, the manual could include an a-priori weighting of those items and domains that should have the strongest influence on the two overall assessments. The relevance of these assessments within AGREE II could thereby be further specified.

Full Text Available During the last decade, many reforms took place in the European Union legal and policy framework. Some of those reforms were motivated by the participation of the European Union and its member States in the World Trade Organization. This paper aims to analyze the role of the European Union as an actor in that organization, paying special attention to its mixed legal nature – EU and Member States. With that purpose, the evolution of the relationship between the EU member States and the EU itself as simultaneous actors at the WTO is studied. The division of competences is also reviewed. Finally, the analysis of the EU position in different negotiation rounds (Uruguay, Doha for the agricultural sector is reviewed as an example of the evolution in the protection of European interests. The paper shows that some changes in the Treaty of Lisbon have strengthened the legal framework for the EU to be heard with a unique voice in the WTO

The as-prepared BaAlF 5 :Eu 2+ are composed of many particles with an average diameter of 40 nm. When excited at 260 nm, the sharp line emission located at 361 nm of Eu 2+ was observed. The optimum doping concentration of Eu 2+ was confirmed to be 5 mol%. The strong ultraviolet emission of Eu 2+ ions in BaAlF 5 :Eu 2+ nanoparticles suggests that these nanoparticles may have potential applications for sensing, solid-state lasers and spectrometer calibration. - Highlights: • BaAlF 5 :Eu 2+ nanophosphors were synthesized via a mild hydrothermal process. • The Van and Huang models were used to research the mechanism of concentration quenching. • The optimum doping concentration of Eu2+ was confirmed to be 5 mol%. - Abstract: Eu 2+ -doped BaAlF 5 nanophosphors were synthesized via a facile one-pot hydrothermal method. The final products were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), and photoluminescence (PL) spectroscopy. XRD results showed that the prepared samples are single-phase. The FE-SEM and TEM images indicated that the prepared BaAlF 5 :Eu 2+ nanophosphors are composed of many rice-shaped particles with an average diameter of 40 nm. When excited at 260 nm, BaAlF 5 :Eu 2+ nanophosphors exhibit the sharp line emissions of Eu 2+ at room temperature. The optimum doping concentration of Eu 2+ was confirmed to be 5 mol%. The Van and Huang models were used to study the mechanism of concentration quenching and the electric dipole–dipole interaction between Eu 2+ can be deduced to be a dominant for quenching fluorescence in BaAlF 5 :Eu 2+ nanophosphors. The strong ultraviolet emission of Eu 2+ in BaAlF 5 :Eu 2+ nanophosphors suggests that these nanoparticles may have potential applications for sensing, spectrometer calibration and solid-state lasers

Electricity generation in the European Union (EU) decreased by 0,7% in the period of 2001 to 2002, reaching 2521,3 billion kWh. Developments varied in different countries. Conventional thermal power plants generated 1340,1 billion kWh, which corresponds to a 53.0% share in the total generation and an increase by 2.7% over the level in the previous year. Generation in nuclear power plants increased by 2.7% to 855.5 billion kWh, which corresponds to a 33,8% share in EU-wide generation. Hydroelectric plants and other plants supplied 15.2% less electricity. Eurostat statistics do not differentiate these data any further. The volume of 332.2 kWh is tantamount to a 13.1% share. In the new EU member countries and the candidate countries, electricity generation showed a moderate increase by 0.4% and 2.1%, respectively. While generation both in conventional power plants and in other plants decreased, a considerable increase is shown for nuclear power generation of +13.5% and +10.6%, respectively [de

The EU in Geneva: The Diplomatic Representation of a System of Governance

Directory of Open Access Journals (Sweden)

Caterina Carta

2013-07-01

Full Text Available The European Union (EU diplomatic system can be conceived as representative of a system of governance, and, through this, of its constitutive independent units. The way in which the EU's political system is represented through diplomatic practices is telling of two interrelated aspects of the EU's international actorness. First, it reveals the link between the foreign policy of a non-state actor and sheds light on the division of competences that characterises the EU's foreign policy-making system. Second, it highlights the complex institutional and organisational features of a non-state diplomatic system. This article locates the puzzle of EU diplomatic activity in the general debate about changes in the institution of diplomacy. Secondly, it explains how post-Lisbon institutional arrangements have been translated into practice in two multilateral delegations: the delegation to the UN and the mission to the WTO in Geneva. It finally draws some preliminary conclusions. The article concludes that beyond competition over the attribution of competences in the EU’s diplomatic governance, different ideas coexist about what ‘locating the EU in the international scene’ means. Pursuing a ‘single voice’ by unifying forms of external representation is not necessarily perceived as the most convenient strategy envisaged by all EU actors. While institutional actors tend to believe that coherence and strength may descend from a more unified system of representation, the member states tend to believe that, in certain circumstances, differentiation could increase the EU’s strength.

Regulatory landscape for cell therapy--EU view.

Science.gov (United States)

McBlane, James W

2015-09-01

This article addresses regulation of cell therapies in the European Union (EU), covering cell sourcing and applications for clinical trials and marketing authorisation applications. Regulatory oversight of cell sourcing and review of applications for clinical trials with cell therapies are handled at national level, that is, separately with each country making its own decisions. For clinical trials, this can lead to different decisions in different countries for the same trial. A regulation is soon to come into force that will address this and introduce a more efficient clinical trial application process. However, at the marketing authorisation stage, the process is pan-national: the Committee for Human Medicinal Products (CHMP) is responsible for giving the final scientific opinion on all EU marketing authorisation applications for cell therapies: favourable scientific opinions are passed to the European Commission (EC) for further consultation and, if successful, grant of a marketing authorisation valid in all 28 EU countries. In its review of applications for marketing authorisations (MAAs) for cell therapies, the CHMP is obliged to consult the Committee for Advanced Therapies (CAT), who conduct detailed scientific assessments of these applications, with assessment by staff from national regulatory authorities and specialist advisors to the regulators.

Production of 147Eu for gamma-ray emission probability measurement

International Nuclear Information System (INIS)

Katoh, Keiji; Marnada, Nada; Miyahara, Hiroshi

2002-01-01

Gamma-ray emission probability is one of the most important decay parameters of radionuclide and many researchers are paying efforts to improve the certainty of it. The certainties of γ-ray emission probabilities for neutron-rich nuclides are being improved little by little, but the improvements of those for proton-rich nuclides are still insufficient. Europium-147 that decays by electron capture or β + -particle emission is a proton-rich nuclide and the γ-ray emission probabilities evaluated by Mateosian and Peker have large uncertainties. They referred to only one report concerning with γ-ray emission probabilities. Our final purpose is to determine the precise γ-ray emission probabilities of 147 Eu from disintegration rates and γ-ray intensities by using a 4πβ-γ coincidence apparatus. Impurity nuclides affect largely to the determination of disintegration rate; therefore, a highly pure 147 Eu source is required. This short note will describe the most proper energy for 147 Eu production through 147 Sm(p, n) reaction. (author)

Designing planning and reporting for good governance of the EU's post-2020 climate and energy goals

International Nuclear Information System (INIS)

Sartor, Oliver; Colombier, Michel; Spencer, Thomas

2015-10-01

The European Union has agreed climate and energy goals for 2030. These objectives include, among others: reduce greenhouse gas emissions by at least 40%; increase the share of renewable energy to at least 27% of total final energy consumption; improve the efficiency of energy consumption by at least 27-30%. But while the targets are clear, what remains less clear is how the EU is to ensure that they are collectively achieved by its 28 Member States and how the actions Member States take to meet their goals by 2030 can be made consistent with Europe's more ambitious, climate objectives to reduce emissions by 80-95% by 2050. This paper puts forward a proposal for a new European Energy Union 'governance mechanism' that attempts to answer these questions, taking into account the priorities of different Member States in the current European context. The EU's 2020 Climate and Energy Package could assign legally-binding national targets to Member States for different aspects of their energy systems, such as for renewable energy, because these targets, although ambitious, remained at the margins of the national energy mix. But as the low-carbon transition makes progress, the changes required to national energy mixes become more fundamental and structural, and national competencies become increasingly important in defining the strategic direction of the energy sector and decarbonization strategies. However, it is also crucial that Member State's nationally determined strategies are consistent with the EU's overarching climate and energy goals, both to 2030 and 2050, and that their progress on key areas of EU relevance and competency can be effectively monitored. Doing this will require a more nuanced approach to governing EU climate policy than the two extremes that are currently presented in the debate: either a) a set of top-down, legally binding targets for all aspects of Energy Union, or b) a harmonised but ultimately very weak planning and reporting instrument with no

The article describes the development of EU policies and regulations on the marketing authorization of medicines. First, it describes the changing perspective of the EU towards the regulation of such authorizations. While its original focus was on the liberalization of national markets, it has today assumed overarching political responsibility for the development and marketing of medicines. Second, the article describes the current, rather fragmented regulatory system. Finally, political perspectives on the integration of markets for medicines are developed.

The purpose of this paper is the measurement of the relative intensities of the most intensive conversion lines of 152 Eu, the determination of as reliable as possible magnitudes of the intensities of γ-quanta using all the available data on γ-radiation of 152 Eu, the measurement of the interval conversion coefficients (ICC) for the most intensive γ-transitions, the determination of the probabilities of the 152 Eu β-decays to the 152 Sm and 152 Gd levels. The conversion lines of the most intensive γ-transitions in the 152 Eu decay are studied and the corresponding ICC are measured on the beta-spectrometers of π√2 and UMB type. The balance for the γ-transitions in the 152 Sm and 152 Gd daughter nuclei are presented. This balance is used to determine the absolute intensities of γ-rays (in terms of the percentage of the 152 Eu decays) and the probabilities of β-transitions to the levels of daughter nuclei. More accurate data on γ-rays and conversion electrons obtained can be used for the calibration of gamma and beta spectrometers

The objective of this report is to provide an early estimate of greenhouse gas (GHG) emissions in the EU-15 and EU-27 for the year 2011. The official submission of 2011 data to the United Nations Framework Convention on Climate Change (UNFCCC) will occur in 2013. In recent years, the EEA and its European Topic Centre on Air Pollution and Climate Change Mitigation have developed a methodology to estimate GHG emissions using a bottom up approach - based on data or estimates for individual countries, sectors and gases - to derive EU GHG estimates in the preceding year (t-1). For transparency, this report shows the country-level GHG estimates from which the EU estimates have been derived. The 2011 estimates are based on the latest activity data available at country level and assume no change in emission factors or methodologies as compared to the official 2012 submissions to UNFCCC (which relate to emissions in 2010). Some Member States estimate and publish their own early estimates of GHG emissions for the preceding year. Where such estimates exist they are clearly referenced in this report in order to ensure complete transparency regarding the different GHG estimates available. Member State early estimates were also used for quality assurance and quality control of the EEA's GHG early estimates for 2011. Finally, the EEA has also used the early estimates of 2011 GHG emissions produced by EEA member countries to assess progress towards the Kyoto targets in its annual trends and projections report (due to be published alongside the present report). In that report, the EEA's early estimates for 2011 were only used for countries that lack their own early estimates to track progress towards national and EU targets. (LN)

International Atomic Energy Agency (IAEA) and European Union officials met this week for the second annual Senior Officials Meeting to review and further strengthen their nuclear-related cooperation. In the past year, the two institutions have improved collaboration in nuclear safety, security, safeguards and peaceful use of nuclear energy through implementing a number of initiatives. In 2013, new contracts for projects have been signed amounting to approximately 24 million euros. These included an EU Council decision to support IAEA nuclear security and verification activities worth of 8.05 million euros. Furthermore, a Memorandum of Understanding establishing a framework for cooperation to help improve nuclear safety was signed, as well as the Practical Arrangement on technical nuclear security issues. The EU and the IAEA have also worked to explore and identify new areas for cooperation such as using nuclear applications for socio-economic development. The meeting addressed enhanced cooperation in the areas of nuclear safety, nuclear security, nuclear applications, nuclear energy and safeguards. Participants agreed on the following steps, including holding a Senior Officials Meeting planned in early 2015 in the premises of the European Commission in Luxembourg

An electric mandate. The EU procedure for harmonising cross-border network codes for electricity

Energy Technology Data Exchange (ETDEWEB)

Jevnaker, Torbjoerg

2012-07-01

The research question addressed in this report is why the EU procedure for developing network codes for electricity was enacted in its particular form. Passed by the EU in 2009, European organisations partly outside of the formal EU structure were given a mandate to make rules that would apply across the EU. This was puzzling given the observed resistance on part of the member states to let go of national control over energy issues. Drawing on institutionalist perspectives, the analysis shows that the procedure would not have been passed without support from and compromise among the Commission, European Parliament and the member states in Council; that parts of the procedure imitated existing practices within related policy areas; that horizontal and vertical specialization within the nation-states along with a Commission actively promoting transnational cooperation changed the feedback mechanisms, which changed the direction of European energy market regulation; and finally, that the new actors played an active role vis-a-vis EU bodies as the latter were legislating on the procedure.

2009-05-15

In this final report for the Swiss Federal Office of Energy (SFOE), the Institute for Environmental Decisions at the Swiss Federal Institute of Technology ETH in Zurich reports on the carbon dioxide emissions of newly homologated vehicles in Switzerland. The report examines if, how, until when and with which pricing-signals Switzerland can adopt the EU's strategy for attaining an average CO{sub 2} emission rate of 130 g/km for newly homologated vehicles. It is noted that the Swiss car market is completely integrated into the EU market. The models used are looked at and demand-side tools such as models on the basis of sanctions and certificates are considered. Further points examined include measures for attaining a further 10 g/km saving, as well as rebound effects and economic feasibility aspects. Finally, monitoring using annual data for result-checking and Swiss joint CO{sub 2} monitoring reporting are discussed.

EU — Russia energy cooperation: major development trends and the present state

Full Text Available The article analyzes the development of EU — Russia energy relations through the lens of the evolution of three parameters: the political agenda (the Energy Dialogue, the institutional structure, and the legal modalities. The identification of these three aspects for assessing the evolution of EU — Russia energy relations is the novelty in the author’s approach. This study aims to identify the previous stages and assess the current state of EU — Russia energy dialogue, since they set out conditions for energy cooperation in the Baltic Sea region. This research is based on a political and legal analysis of various documents and employs various international relations theories (including integration theories. The article demonstrates that the EU nd Russia have made a transition to the integration agenda manifested in the Energy Dialogue (its current goal is the creation of a common European energy market. The author describes the process of gradual consolidation of transgovernmental and transnational institutions, which leads to depoliticization of cooperation and mutual socialization of the partners. Finally, legal discussions on the development of common rules have become more constructive. In sum, the current situation in EU — Russia energy relations is favourable and positively affects cooperation in the Baltic Sea region.

Sources of conflicts in climate policy within the EU. An economic analysis

Energy Technology Data Exchange (ETDEWEB)

Aaheim, H. Asbjoern; Bretteville, Camilla

1999-09-01

This report is a part of a study of the potential for the EU to take on leadership in the climate negotiations. The aim is to sort out factors that may explain the different economic interests in cutting CO{sub 2}-emissions within the EU. It is based on the idea that interests occur as a result of different perception of the cost of emission cuts among stakeholders. Sector-based comparisons of France, Germany, Italy, the Netherlands, Spain and United Kingdom indicate that the conflicts resulting from an announcement of emission cuts are likely to be moderate in Germany, the Netherlands and UK, while the possibilities for conflicts in France, Italy and Spain are significantly higher. The explanation can to a large extent be found by the possibilities for reducing emissions in the electricity sector. The differences facing the different countries when it comes to emission cuts might explain why the EU has not succeeded in implementing common measures across the member countries. To prepare for a common policy, a co-ordination of the electricity market should be given priority. Meanwhile, the differentiation of targets agreed upon after Kyoto clearly contributes to mitigate conflicts. However, new conflicts may occur as a result. The present analysis points out that Italy has got very strict targets compared with the other countries, while the targets for the Netherlands and Spain are moderate. 21 refs., 15 figs., 8 tabs.

The study evaluates the impacts of EU climate policy on the emission allowance price, electricity prices, the competitiveness of industry and macroeconomic developments in the third EU emission trading period 2013-2020. The economic impacts of climate policy on Finland are compared to the impacts on the entire EU area. It turns out that due to its cold climate and heating energy demand, higher export intensity of the economy and higher energy intensity of the industry Finland pays a higher price for EU climate policy in terms of output and employment losses than the EU on average. The study examines the macroeconomic effects of climate policy also in the more distant future, assuming that climate policy is tightened further in the 2020s. Climate policy implemented by emission trading means that the long-term economic growth in the EU area depends essentially on emission-free electricity production, and no longer on other growth factors, such as the labour supply and productivity growth.

Cathodoluminescence properties of yttrium aluminum garnet doped with Eu2+ and Eu3+ ions

International Nuclear Information System (INIS)

Trofimov, A. N.; Petrova, M. A.; Zamoryanskaya, M. V.

2007-01-01

Yttrium aluminium garnet (YAG) doped with Eu 2+ and Eu 3+ ions is very interesting as a phosphor for conversion of light-emitting diode light for white light sources. The europium ion occupies the structural position of yttrium in yttrium aluminium garnet and has valence state Eu 3+ . Our sample was doped with Zr 4+ , which is why some of the europium ions had valence state Eu 2+ . As a rule, luminescence of Eu 3+ ions is observed in the orange and red range of spectrum. The luminescence of Eu 2+ in yttrium aluminum garnet is characterized by an intensive broad band with maximum of intensity at about 560 nm (green color). In this work, we studied the intensity and decay time dependences on europium concentration, and the influence of excitation power density on the cathodoluminescence of the sample. The most interesting result is the change of visible cathodoluminescence color in dependence on the density of the exciting power

Negative pressure driven valence instability of Eu in cubic Eu0.4La0.6Pd3

Pandey, Abhishek; Mazumdar, Chandan; Ranganathan, R

We report the change in the valency of Eu-ions in the binary intermetallic cubic compound EuPd 3 induced by La doping at rare-earth sites. Doping of La generates negative chemical pressure in the lattice, resulting in a significant increase of the lattice parameter without altering the simple-cubic structure of the compound. Results of dc-magnetic measurements suggest that this increase in the lattice parameter is associated with the valence transition of Eu-ions from Eu 3+ to a mixed-valent state. As Eu 2+ -ions possess a large magnetic moment, this valence transition significantly modifies the magnetic behavior of the compound. In contrast to introducing boron at the vacant body center site of the unit cell to change the valency of Eu-ions, as in the case of EuPd 3 B, our results suggest it can also be altered by doping a rare-earth ion of larger size at the lattice site of Eu in EuPd 3 .

A liquid Eu precursor, bis(normal-propyl-tetramethylcyclopentadienyl)europium has been synthesized. This precursor exists as a liquid at temperatures higher than 49 °C, has a moderately high vapor pressure, contains no oxygen in its molecular structure, and can be distilled to high purity. These properties make it ideal for doping using a chemical vapor or atomic layer deposition method, and provide a degree of control previously unavailable. As a precursor the Eu exists in the divalent valance state, however, once doped into GaN by organometallic vapor phase epitaxy, the room-temperature photoluminescence of the Eu-doped GaN exhibited the typical red emission due to the intra-4f shell transition of trivalent Eu. After variation of the growth temperature, it was found that divalent Eu could be stabilized in the GaN matrix. By tuning the Fermi level through donor doping, the ratio of Eu 2+ to Eu 3+ could be controlled. The change in valence state of the Eu ions was confirmed using X-ray absorption near-edge structure. - Highlights: • A liquid Eu precursor was synthesized and its properties were characterized. • Precursor has a low melting point and a moderately high vapor pressure. • Does not contain oxygen in its molecular structure. • Eu can changed its valance state when incorporated into GaN. • Valence state of Eu in GaN can be controlled by donor doping.

Romaniuk, Ryszard S.

2013-10-01

Accelerator science and technology is one of a key enablers of the developments in the particle physic, photon physics and also applications in medicine and industry. EuCARD2 is an European research project which will be realized during 2013-2017 inside the EC FP7 framework. The project concerns the development and coordination of European Accelerator Research and Development. The project is particularly important, to a number of domestic laboratories, due to some plans to build large accelerator infrastructure in Poland. Large accelerator infrastructure of fundamental and applied research character stimulates around it the development and industrial applications as well as biomedical of advanced accelerators, material research and engineering, cryo-technology, mechatronics, robotics, and in particular electronics - like networked measurement and control systems, sensors, computer systems, automation and control systems. The paper presents a digest of the European project EuCARD2 which is Enhanced European Coordination for Accelerator Research and Development. The paper presents a digest of the research results and assumptions in the domain of accelerator science and technology in Europe, shown during the final fourth annual meeting of the EuCARD - European Coordination of Accelerator R&D, and the kick-off meeting of the EuCARD2. There are debated a few basic groups of accelerator systems components like: measurement - control networks of large geometrical extent, multichannel systems for large amounts of metrological data acquisition, precision photonic networks of reference time, frequency and phase distribution, high field magnets, superconducting cavities, novel beam collimators, etc. The paper bases on the following materials: Internet and Intranet documents combined with EuCARD2, Description of Work FP7 EuCARD-2 DoW-312453, 2013-02-13, and discussions and preparatory materials worked on by Eucard-2 initiators.

EU stresstest national report of Germany. Progress report

2011-09-15

The European Council concluded in March that the safety of all EU nuclear plants should be reviewed on the basis of a comprehensive and transparent risk assessment (''stress test''). The German Bundestag (Federal Parliament) called upon the German Federal Government on 17{sup th} March 2011 to conduct a comprehensive review of the safety requirements for the German nuclear power plants. The competent Federal Ministry asked its advisory body, the RSK, to perform this review. The findings of the RSK safety review were presented to the public on 17{sup th} May 2011. ENSREG published the scope and modalities for comprehensive risk and safety assessments of EU nuclear power plants on 13{sup th} May 2011. This ''Declaration of ENSREG'' determines the concept, methodology and time schedule of the EU stress test. The BMU as the federal regulator in Germany asked the Laender authorities to initiate the EU stress tests according to the ENSREG Declaration. The ''stress tests'' were started by all German licensees with the self-commitment to deliver the progress report by 15{sup th} August 2011 and the final report by 31{sup st} October 2011. The structure of the German national report follows mainly the chapters according to the ENSREG Declaration. In addition detailed insights from the broader scope and specific methodology of the RSK safety review are also included in the chapters. In chapter 6 are in particular insights from the RSK safety review related to initiating events caused by man-made hazards, such as an aircraft crash, terrorist attack or cyber attacks. The licensee progress reports and the certificates by the competent federal state regulators reflect an interim state. Further work is planned and should take additional guidance to be given by ENSREG into account. The Federal State authorities have so far reviewed the licensee reports in terms of completeness, the adequate application of the ENSREG

Energy independence of the EU and the role of France

International Nuclear Information System (INIS)

2014-03-01

After having outlined that the Ukrainian crisis has revealed the challenge of the EU energy independence and the issue of its dependence, and also indicated the evolutions of gas imports for some European countries between 1995 and 2011, this publication discusses the level of this energy dependence as it appears through the evolution of energy resources, and through the evolution of the final energy mix. It also briefly comments the position of member states. Then, it analyses the influence of French choices on this dependence level (contribution of France to a lower dependence, evolution of energy dependence rates of European countries), and defines the potential role France could play and actions France could implement for a positive evolution of EU energy independence

Differences and similarities between the EU and non-EU citizens

Full Text Available Initially, the European Union had a purely economic connotation, as his intent was the free movement of factors of production, in order to create a competitive internal market and achieving a rational distribution of resources. For this reason, the individual was seen simply as a worker and for this purpose the first aspects that are disciplined within the EU are those contained in this sphere. In the Treaty of Rome, which established the European Economic Community (EEC, the freedom of free movement was reserved for only a few special categories of workers, who were active subjects economically, since what resulted essential at the time was the creation of an internal market. Later the Maastricht Treaty, on one side marks the transition from the EEC to the EU, on the other presents for the first time the "European citizenship", making the free movement an autonomous right of every citizen belonging to a Member State. In this way the free movement is exercised not only for the economic purposes of the Treaties. In December 2000 the Charter of Fundamental Rights or the Charter of Nice was compiled and signed, which defines that the EU seeks to promote a balanced development and ensures free movement of persons, goods, services and capital, and also the freedom of residence. Main objective of this manuscript is an analysis of the differences and similarities between the EU and non-EU citizens.

Graphical abstract: - Highlights: • Silver nanoparticles are precipitated from the borate glasses during the melting process without any further heat treatment. • The reduction of Eu 3+ ions to Eu 2+ ions is presented in this material. • The intensity of Ag + luminescence. • The introduction of Eu ions accelerated the reaction between Eu 2+ ions and silver ions inducing the silver clusters formation. - Abstract: Ag + doped sodium borate glasses with different Eu ions concentration were prepared by the melt-quenching method. The absorption at about 410 nm which was caused by the surface plasmon resonance (SPR) of Ag nanoparticles (NPs) is promoted with increasing of Eu ions concentration. Meanwhile, the luminescent spectra showed that the emission intensity of Ag + decreased while that of the Ag aggregates increased simultaneously. The results indicated that the Ag ions intend to form the high-polymeric state such as Ag aggregates and nanoparticles with increasing of europium ions. Owing to the self-reduction of Eu 3+ to Eu 2+ in our glass system, it revealed that Ag + has been reduced by the neighboring Eu 2+ which leads to the formation of Ag aggregates and the precipitation of Ag NPs in the matrix. In addition, energy transfer (ET) process from Ag + /Ag aggregates to the Eu 3+ was investigated for the enhancement of Eu 3+ luminescence

The EU-strategy against soil acidification. Concept of the critical load; Die EU-Strategie gegen Bodenversauerung. Konzept der kritischen Belastung

Energy Technology Data Exchange (ETDEWEB)

Trautwein, W.P.

1998-10-01

The development of so-called `novel forest damages` is considered to be - at least partly - a result of the impact of certain air pollutants such as sulphur and nitrogen oxides; these precipitate as acid rain and acidify the soil, thus damaging sensitive ecosystems, e.g. forests. To combat acidification, the EU Commission has produced a Community strategy, which is based on the concept of critical loads. The DGMK report 548 deals with this concept of critical loads and with the measures to combat soil acidifiction. It explains that critical loads are not damage thresholds, but environmental standards, and deviation does not necessarily required any action. It demonstrates, why the reduction of sulphur dioxide emissions, formed during the utilization of fluid fuels, is not a cost-effective measures. It proposes continued implementation of agreed plans for emission reduction, before additional legislative steps are considered. This report contains information to June 1998 inclusive. (orig.) [Deutsch] Die Entstehung der sogenannten `neuartigen Waldschaeden` fuehrt man zum Teil auf die Einwirkung gewisser Luftschadstoffe wie Schwefel- und Stickoxide zurueck, die als saurer Regen auf die Erde niedergehen und zu einer Versauerung des Bodens und damit zu einer Schaedigung empfindlicher Oekosysteme wie der Waelder fuehren koennen. Die EU-Kommission hat eine Strategie der EU zur Bekaempfung dieser Versauerung entwickelt, die auf dem Konzept der kritischen Belastungen beruht. Der DGMK-Bericht 548 setzt sich mit diesem Konzept der kritischen Belastungen sowie mit den Massnahmen zur Bekaempfung der Bodenversauerung auseinander. Er erlaeutert, dass kritische Belastungen keinen Schwellenwert, sondern einen Umweltstandard darstellen, aus dessen Ueberschreitung nicht zwingend ein Handlungsbedarf abgeleitet werden kann. Er erlaeutert ferner, warum vor allem die Reduktion der Schwefeldioxidemissionen, die beim Einsatz fluessiger Kraft- und Brennstoffe entstehen, keine

Vaccination policies of immigrants in the EU/EEA Member States-the measles immunization example.

Bica, Mihai A; Clemens, Ralf

2018-06-01

In 2015-16, the European Union/European Economic Area Member States (EU/EEA MSs) experienced an unprecedented volume and rate of migration, posing serious challenges to existing national immunization systems and strategies and raising the questions of where, when and who to vaccinate. We assessed existing strategies for vaccinating immigrant populations in the EU/EEA using measles as an example of the most important vaccine-preventable diseases. In this cross-sectional study, conducted from March to May 2016, an electronic questionnaire was sent to the Heads of National Immunization Technical Advisory Groups (NITAGs) or equivalent policy-making bodies in each of the 31 EU/EEA Member States. Responses were entered into a structured database and validated by survey responders for final analysis. Validated responses from all 31 EU/EEA NITAGs or equivalents showed that there is no common measles immunization policy for European immigrants. Policies vary widely from no policy at all (9 of 31, 29%) to vaccination of all comers (2 of 31, 6%), or vaccination of selected cohorts based on vaccination history (17 of 31, 55%) or serum antibody analysis (2 of 31, 6%). Further, the operational responsibilities for immigrant vaccination and documentation methods are not unified within the EU/EEA region. With some notable exceptions immunization policies to contain spread of infectious diseases through migration are either non-existent or vary widely between countries in the EU/EEA. With freedom of movement within the EU/EEA there ought to be harmonization and a common EU/EEA vaccination strategy to replace national policies for immigrant populations.

How will the EU climate adaptation strategy affect EU agricultural policies?

DEFF Research Database (Denmark)

Nielsen, Helle Ørsted; Karali, Eleni; Castellari, Sergio

A key objective in the EU Strategy on adaptation to climate change (COM (2013) 216 final) is to ensure mainstreaming, i.e. integration, of adaptation measures into European sectoral policies. The Common Agricultural Policy (CAP) is one such sectoral policy which is prioritised in the strategy...... as an area to be climate proofed. The CAP is under revision and will be reformed for the 2014-2020 period with the explicit objectives of strengthening the competitiveness and the sustainability of agriculture (EC). Climate change adaptation objectives are included in the proposal for a greening...... of the single payment scheme (2011/0280 (COD), and the proposal for the Rural Development Fund also specifically sets out climate change adaptation as a cross-cutting objective to which rural development funding must contribute 2011/0282 (COD).

EU policies on car emissions and fuel quality. Reducing the climate impact from road transport

Energy Technology Data Exchange (ETDEWEB)

Christensen, Anne Raaum; Gulbrandsen, Lars H.

2012-07-01

Transport is the second biggest source of greenhouse gas (GHG) emissions in the EU, and contributes about one-quarter of the EU's total emissions of CO{sub 2}. Significant reductions in GHG emissions from transport are required if the EU is to achieve its long-term climate goals. This report examines the making and implementation of two of the regulations the EU has put in place to lower emissions from the transport sector: the EU's revised Fuel Quality Directive (Directive 2009/30/EC) and the cars/CO{sub 2} regulation (Regulation (EC) 443/2009). It was found that the relevance of various theories of policymaking in the EU varies with different policy phases. A policy-network understanding of EU policymaking is strengthened when assessing the policy-initiation phase. The Commission played a key role in this phase and drafted legislation in close collaboration with the car and oil refining industries. An intergovernmentalist understanding of EU policy-making is strengthened when assessing the decision-making phase. In this phase, member states defending the interests of their domestic industries had strong influence, but the European Parliament played an important role in this phase too, employing its power in the co-decision procedure. Finally, the implementation process is best understood as a multi-level governance process in which several actors and institutions - notably the Commission, member states, industries, and NGOs - influenced the process.

The AGREE code was originally developed as a multi physics simulation code to perform design and safety analysis of Pebble Bed Reactors (PBR). Currently, additional capability for the analysis of Prismatic Modular Reactor (PMR) core is in progress. Newly implemented fluid model for a PMR core is based on a subchannel approach which has been widely used in the analyses of light water reactor (LWR) cores. A hexagonal fuel (or graphite block) is discretized into triangular prism nodes having effective conductivities. Then, a meso-scale heat transfer model is applied to the unit cell geometry of a prismatic fuel block. Both unit cell geometries of multi-hole and pin-in-hole types of prismatic fuel blocks are considered in AGREE. The main objective of this work is to verify and validate the heat transfer model newly implemented for a PMR core in the AGREE code. The measured data in the HENDEL experiment were used for the validation of the heat transfer model for a pin-in-hole fuel block. However, the HENDEL tests were limited to only steady-state conditions of pin-in-hole fuel blocks. There exist no available experimental data regarding a heat transfer in multi-hole fuel blocks. Therefore, numerical benchmarks using conceptual problems are considered to verify the heat transfer model of AGREE for multi-hole fuel blocks as well as transient conditions. The CORONA and GAMMA+ codes were used to compare the numerical results. In this work, the verification and validation study were performed for the heat transfer model of the AGREE code using the HENDEL experiment and the numerical benchmarks of selected conceptual problems. The results of the present work show that the heat transfer model of AGREE is accurate and reliable for prismatic fuel blocks. Further validation of AGREE is in progress for a whole reactor problem using the HTTR safety test data such as control rod withdrawal tests and loss-of-forced convection tests.

Intra-EU Direct Investment and Enlargement

Festa Andrea

2015-03-01

Full Text Available This paper examines the determinants of the intra-EU direct investment (IDI into the New Member States (NMS using a panel dataset of bilateral capital flows for the period 1993-2013. It is found out by using a simple gravity model that EU membership is the most important determinant. Unlike previous studies including non-EU countries, the distance is insignificant, which is caused by proximity of these countries to one another. A separate analysis focused on subgroups of accession countries gives some evidence that even when size of their economy, distance, institutional quality and EU accession are taken into account, Central European countries receive more IDI than the Baltic and the Balkan states. On the contrary to that, the analysis restricted to the Balkan countries which have joined the EU shows the inexistence of a negative Balkans effect in attracting foreign investment. This finding is relevant because previous studies demonstrate a persistent negative Balkans effect for non-EU Balkan countries and suggests a crucial impact of the EU accession in determining the intra-EU capital flows.

The EuReDatA Association was formed to harmonize research and development work in the field of Reliability Data Banks, in particular by promoting the adoption of agreed definitions and procedures aimed at the exchange of information and experience on reliability data acquisition among members. To solve the problems arising from the organization and control of the large effort various ad-hoc project groups were created to work out solutions for specific topics. This paper describes the effort made and the results obtained by such specialized groups which have already produced reports that could be utilized by people active in an ever-widening variety of disciplines to facilitate the useful exchange of reliability information among them.

The impact of Septoria tritici Blotch disease on wheat: An EU perspective.

Science.gov (United States)

Fones, Helen; Gurr, Sarah

2015-06-01

Zymoseptoria tritici is the causal agent of one of the European Union's most devastating foliar diseases of wheat: Septoria tritici Blotch (STB). It is also a notable pathogen of wheat grown in temperate climates throughout the world. In this commentary, we highlight the importance of STB on wheat in the EU. To better understand STB, it is necessary to consider the host crop, the fungal pathogen and their shared environment. Here, we consider the fungus per se and its interaction with its host and then focus on a more agricultural overview of the impact STB on wheat. We consider the climatic and weather factors which influence its spread and severity, allude to the agricultural practices which may mitigate or enhance its impact on crop yields, and evaluate the economic importance of wheat as a food and animal feed crop in the UK and EU. Finally, we estimate the cost of STB disease to EU agriculture. Copyright © 2015. Published by Elsevier Inc.

Non-stoichiometric (Eu,Ca):WO 3 and Eu:CaWO 4 nanoparticles with anti-tumor activity are synthesized in a sol-gel method by adding excessive Eu 3+ and Ca 2+ ions to tungsten oxide crystal structure. Colorimetric assay shows that 10 nm (Eu,Ca):WO 3 and Eu:CaWO 4 nanoparticles can effectively inhibit growth of mammary cancer cells without any harm to normal cells. Nanoparticles are characterized by X-ray diffraction, high resolution transmission electron microscopy and fluorescence optical spectrometry. Nanomaterials, insoluble in synthesized water, have complicated self-charging surfaces that trap mammary cancer cells. Surface self-charging effect is suggested as the inhibition mechanism. (author)

The as-prepared BaAlF{sub 5}:Eu{sup 2+} are composed of many particles with an average diameter of 40 nm. When excited at 260 nm, the sharp line emission located at 361 nm of Eu{sup 2+} was observed. The optimum doping concentration of Eu{sup 2+} was confirmed to be 5 mol%. The strong ultraviolet emission of Eu{sup 2+} ions in BaAlF{sub 5}:Eu{sup 2+} nanoparticles suggests that these nanoparticles may have potential applications for sensing, solid-state lasers and spectrometer calibration. - Highlights: • BaAlF{sub 5}:Eu{sup 2+} nanophosphors were synthesized via a mild hydrothermal process. • The Van and Huang models were used to research the mechanism of concentration quenching. • The optimum doping concentration of Eu2+ was confirmed to be 5 mol%. - Abstract: Eu{sup 2+}-doped BaAlF{sub 5} nanophosphors were synthesized via a facile one-pot hydrothermal method. The final products were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), and photoluminescence (PL) spectroscopy. XRD results showed that the prepared samples are single-phase. The FE-SEM and TEM images indicated that the prepared BaAlF{sub 5}:Eu{sup 2+} nanophosphors are composed of many rice-shaped particles with an average diameter of 40 nm. When excited at 260 nm, BaAlF{sub 5}:Eu{sup 2+} nanophosphors exhibit the sharp line emissions of Eu{sup 2+} at room temperature. The optimum doping concentration of Eu{sup 2+} was confirmed to be 5 mol%. The Van and Huang models were used to study the mechanism of concentration quenching and the electric dipole–dipole interaction between Eu{sup 2+} can be deduced to be a dominant for quenching fluorescence in BaAlF{sub 5}:Eu{sup 2+} nanophosphors. The strong ultraviolet emission of Eu{sup 2+} in BaAlF{sub 5}:Eu{sup 2+} nanophosphors suggests that

Harmful Tax Competition in the EU with Reference to Croatia

Full Text Available The process of globalisation has led, among other things, to harmful tax competition. This paper considers the efforts within the EU in combating harmful tax competition (Code of Conduct on Business Taxation and their effects when taking into account the EU regulations in relation to state aids. Considering a number of problems in the implementation of the Code, and the numerous criticisms with regard to the validity of the combat against harmful tax competition – it is difficult to give a final answer about its success. Croatian tax system, and the corporation tax in particular, are analysed in the light of the aforementioned problems. The advantages of the equal treatment of domestic and foreign investors, as well as the certain elements of state aids in tax benefits, are pointed out.

Hyperfine interactions in europium orthophosphate EuPO{sub 4} were investigated using {sup 151}Eu Mössbauer spectroscopy from 6 to 300 K. The value of the quadrupole splitting and the asymmetry parameter were refined and further substantiated by nuclear forward scattering data obtained at room temperature. The temperature dependence of the relative absorption was modeled with an Eu specific Debye temperature of 221(1) K. Eu partial lattice dynamics were probed by means of nuclear inelastic scattering and the mean force constant, the Lamb-Mössbauer factor, the internal energy, the vibrational entropy, the average phonon group velocity were calculated using the extracted density of phonon states. In general, Eu specific vibrations are characterized by rather small phonon energies and contribute strongly to the total entropy of the system. Although there is no classical Debye like behavior at low vibrational energies, the average phonon group velocity can be reasonably approximated using a linear fit.

EU Think Tank Fora as Transaction Cost Reducers: A Study of Informal Interest Intermediation in the EU

Directory of Open Access Journals (Sweden)

Marybel Perez

2014-05-01

Full Text Available By examining the organisational structure of EU think tank fora (seminars, workshops and conferences, this article proposes that fora can play the role of transaction cost reducers in EU policymaking. I argue that certain aspects of EU policymaking, including i controlled processes of consultation, ii diminishing costs of management, and iii the risk of state capture, incentivise EU institutions to outsource part of the consultation activity to policy actors that can help EU institutions fulfil their informational and legitimacy needs. I argue that think tanks are able to play this role because they i reduce information asymmetries by connecting a wide variety of policy actors and ii act as intermediaries that mitigate opportunistic behaviour. The empirical assessment reveals that the dimensions characterising transactions are present in EU think tank fora. It shows that policy actors that do not usually participate in formal consultation processes frequently attend fora where they meet representatives of EU institutions, particularly Parliament and Commission representatives.

Up to now, orchestrating the coexistence of Eu 2+ and Eu 3+ activators in a single host lattice has been an extremely difficult task, especially for the appearance of the characteristic emission of Eu 2+ and Eu 3+ in order to generate white light. Nevertheless, here we demonstrate a new Eu 2+ /Eu 3+ coactivated SrAl 3 BO 7 nanocrystalline phosphor with abundant and excellent multichannel luminescence properties. A series of Eu 2+ /Eu 3+ coactivated SrAl 3 BO 7 nanocrystalline phosphors were prepared through a Pechini-type sol-gel method followed by a reduction process. With excitation of UV/NUV light, the prepared SrAl 3 BO 7 :Eu 2+ ,Eu 3+ phosphors show not only the characteristic f-f transitions of Eu 3+ ion ( 5 D J → 7 F J,J' , J, J' = 0-3), but also the 5d → 4f transitions of Eu 2+ ion with comparable intensity from 400 to 700 nm in the whole visible spectral region. The luminescence color of the SrAl 3 BO 7 :Eu 2+ ,Eu 3+ phosphor can be tuned from blue, blue-green, white, and orange to orange-red by changing the excitation wavelength, the overall doping concentration of europium ions (Eu 2+ , Eu 3+ ), and the relative ratio of Eu 2+ to Eu 3+ ions to some extent. A single-phase white-light emission has been realized in SrAl 3 BO 7 :Eu 2+ ,Eu 3+ phosphor. The obtained SrAl 3 BO 7 :Eu 2+ ,Eu 3+ phosphor has potential application in the area of NUV white-light-emitting diodes.

The Impact of the Explosion of EU News on Voter Choice in the 2014 EU Elections

Directory of Open Access Journals (Sweden)

Jan Kleinnijenhuis

2016-02-01

Full Text Available The European elections in 2014 were the first to be held after a long period in which EU-related news was prominent in the media. They were held after years of daily news about the euro crisis and after months of news about the popular uprising in the Ukraine against president Yanukovych, who had refused to sign the association agreement with the EU. This could have invited political parties to overcome the usual problem of low salience of EU issues by strongly profiling themselves on EU issues. Turnout at the 2014 EU elections, however, remained low, hinting that parties were unable to convert the attention for European issues into enthusiasm for their party at the European elections. This paper asks how vote choice was influenced by party campaigning on EU related issues. A news effects analysis based on a content analysis of Dutch newspapers and television, and on a panel survey among Dutch voters revealed that EU issues functioned as wedge issues: the more strongly parties were associated in the news with the euro crisis and the Ukraine, the less they succeeded in mobilizing voters.

Carbon pricing in the EU: Evaluation of different EU ETS reform options

International Nuclear Information System (INIS)

Brink, Corjan; Vollebergh, Herman R.J.; Werf, Edwin van der

2016-01-01

This paper studies various options to support allowance prices in the EU Emissions Trading System (ETS), such as adjusting the cap, an auction reserve price, and fixed and variable carbon taxes in addition to the EU ETS. We use a dynamic computable general equilibrium model that explicitly allows for allowance banking and for a detailed cost-effectiveness analysis at the EU Member State level. We find that tightening the cap provides an ad hoc solution to the fundamental issue of the robustness of the effective carbon price, while introducing a price component to the ETS brings structural carbon price support in times of negative demand shocks for emission allowances. These price-based policies still benefit from the intertemporal flexibility through the banking provision in the EU ETS by re-allocating emissions over time with stronger emission reductions in early years and emission increases in later years. A higher emission price has a larger negative impact on the new Member States' economies than on other Member States. Furthermore, introducing a carbon tax in addition to the EU ETS decreases the price of allowances, resulting in welfare gains for net buyers of allowances while net sellers are worse off. - Highlights: • We analyse reform options for European Union Emission Trading System (EU ETS) with a CGE model. • Variable carbon tax and auction reserve price support carbon price at least cost. • Price-based reforms decrease early emissions but increase later emissions through banking. • New Member States' economies are affected more than others by higher CO_2 prices. • Lower allowance prices due to a carbon tax are unfavourable to net sellers of allowances.

The EU-Africa Energy Partnership: Towards a mutually beneficial renewable transport energy alliance?

International Nuclear Information System (INIS)

Charles, Michael B.; Ryan, Rachel; Oloruntoba, Richard; Heidt, Tania von der; Ryan, Neal

2009-01-01

The European Union's EU-Africa Energy Partnership, with respect to its emphasis on transport fuels, aims to ensure that Member States can fulfil agreed upon commitments to sustainable energy via the importation of biomass grown in sub-Saharan Africa. This policy aims to reduce the dependence of developing sub-Saharan nations on fossil-fuels, while ensuring the global proliferation of alternative transport energy generation as a means to combat climate change. Though the policy seems equitable in theory, and indeed mutually beneficial, several important issues arise. The paper examines the EU-Africa Energy Policy in the context of biofuels in particular, with a view to identifying potential flaws and imbalances and making policy recommendations. Aside from establishing critical uncertainties, the study adduces environmental science, historical comparanda and economic theory in order to assess the various threats associated with aspects of the policy, especially in light of previous policies that have stifled the development of sub-Saharan economies. In addition, the paper has substantial relevance to developing and newly industrialized nations in Asia and South America also seeking to invest in biomass cultivation and production.

A liquid Eu precursor, bis(normal-propyl-tetramethylcyclopentadienyl)europium has been synthesized. This precursor exists as a liquid at temperatures higher than 49 °C, has a moderately high vapor pressure, contains no oxygen in its molecular structure, and can be distilled to high purity. These properties make it ideal for doping using a chemical vapor or atomic layer deposition method, and provide a degree of control previously unavailable. As a precursor the Eu exists in the divalent valance state, however, once doped into GaN by organometallic vapor phase epitaxy, the room-temperature photoluminescence of the Eu-doped GaN exhibited the typical red emission due to the intra-4f shell transition of trivalent Eu. After variation of the growth temperature, it was found that divalent Eu could be stabilized in the GaN matrix. By tuning the Fermi level through donor doping, the ratio of Eu{sup 2+} to Eu{sup 3+} could be controlled. The change in valence state of the Eu ions was confirmed using X-ray absorption near-edge structure. - Highlights: • A liquid Eu precursor was synthesized and its properties were characterized. • Precursor has a low melting point and a moderately high vapor pressure. • Does not contain oxygen in its molecular structure. • Eu can changed its valance state when incorporated into GaN. • Valence state of Eu in GaN can be controlled by donor doping.

Eu{sup 3+} and Eu{sup 2+} co-doped calcium aluminosilicate glass–ceramics have been prepared by devitrification of calcium aluminosilicate glass using heat-treatment. Control of crystallization in the glass–ceramics was studied by X-ray diffraction (XRD) and Raman spectroscopy. The results showed that crystalline phases in glass–ceramic belong to the family of melilite Ca{sub 2}Mg{sub 0.25}Al{sub 1.5}Si{sub 1.25}O{sub 7} as the major phase and anorthite CaAl{sub 2}Si{sub 2}O{sub 8} as the minor phase. Luminescent properties were investigated by emission; lifetime and the color points were calculated. Emission spectra showed that Eu{sup 2+} entered into the crystalline phase in a two steps mechanism: first as Eu{sup 3+} which is then reduced to Eu{sup 2+}. This incorporation in the crystal enhanced Eu{sup 2+} emission with increasing time of heat-treatment and therefore crystallization. - Highlights: • Crystallization of doped glass–ceramics by heat-treatment controlled by microRaman. • Crystalline phases consist of melilite and anorthite. • Eu{sup 3+} and Eu{sup 2+} emissions characterized by their lifetime and color indexes. • Crystallization process modified efficiently the emission color point.

Point Climat no. 25 'Auction revenues in EU ETS Phase 3: a new public resource'

International Nuclear Information System (INIS)

Chevaleyre, Guillaume; Berghmans, Nicolas

2013-01-01

Among the publications of CDC Climat Research, 'Climate Briefs' presents, in a few pages, hot topics in climate change policy. This issue addresses the following points: As from 1 January 2013, auctions will become the main mode for distributing CO 2 allowances within the EU ETS. By 2020, almost one billion EUAs will be sold every year and generate income for Member States. Although sales of Phase 3 allowances have begun, uncertainty still surrounds the total amount of allowances to be auctioned. In particular, benchmark free allocations, the potential review of the auction timetable and the exemption of international flights from the EU ETS will impact the final amounts auctioned and the EUA price. These factors will affect the final auction revenues of each Member States differently. Government authorities will need to take account of the variability of this new financial resource

Consequences of EU air quality directives for spatial development plans in various EU countries

International Nuclear Information System (INIS)

Koelemeijer, R.B.A.; Blom, W.F.; Bouwman, A.A.; Hammingh, P.; Backes, C.W.

2005-01-01

Over the past few years, the highest Dutch court of justice has rejected many building plans for new homes, roads and businesses because of reasons related to EU air quality limit values. This has made it clear that detailed impact assessments are necessary to having plans approved for permits, and that failure to achieve limit values can be a reason to reject a plan. An investigation to see whether such issues have also played a role in other EU countries has proven the contrary. Only a few similar court cases have taken place in other countries, while air quality limit values are breached in other EU countries as well. The reason is that the Netherlands has implemented the first EU Daughter Directive in a relatively strict manner in comparison to other countries, in particular: Adopting a strict legal coupling of air quality and spatial planning policies, with many types of plans being subject to an air quality impact assessment; Perceiving limit values as absolute limit values, whereas in many other countries a need to meet a limit value is weighted with other interests in granting permits; Applying limit values to the whole country. Although this application is, in principle, valid for all EU member states, some member states apply limit values only to locations where people can be exposed; Since air quality assessment is detailed in the Netherlands, many locations are appointed where air quality limit values are breached. Clearly, the role of limit values in granting permits for plans differs considerably among the EU countries, while the underlying EU legislation is the same, and while limit values are breached in other countries as well [nl

No fracking way: how the EU-US trade agreement risks expanding fracking

International Nuclear Information System (INIS)

2014-03-01

A major trade deal currently being negotiated between the European Union (EU) and the United States (US) threatens the power of governments to protect communities, citizens and the environment from risky new technologies such as fracking. The Transatlantic Trade and Investment Partnership (TTIP) covers a huge range of issues and sectors, including food safety, genetically modified products, toxic chemicals, highly polluting fuels and data protection. The talks threaten to weaken or roll-back democratically agreed safeguards put in place to protect the environment and citizens - for the sake of corporate profits. The talks are likely to favour safeguards for corporate investments over safeguards for citizens and the environment, allowing companies to seek compensation when government decisions affect their profits. This could benefit companies seeking to exploit natural resources through hazardous technologies whose activities may be affected by environmental or health regulations. Fracking - or high-volume hydraulic fracturing - is used to extract hard-to-access unconventional fossil fuels, such as shale gas and oil, tight gas and coal bed methane. Fracking will increase available gas supplies, locking us into fossil fuel dependency for several decades. There is growing evidence of huge health and environmental risks and impacts from fracking and this is leading to widespread public opposition at the community level, both in the EU and the US. This brief analyses how the TTIP could limit governments' ability to regulate the development and expansion of fracking. It argues that the TTIP could dangerously thwart government efforts to address climate change and to protect citizens; could expand fracking by removing the ability of governments to control natural gas exports; and could mean that states would be forced to pay millions in compensation to corporations for profits lost to regulation. It calls on the EU and the US to exclude investor-state dispute settlement

Luminescent properties of green- or red-emitting Eu2+-doped Sr3Al2O6 for LED

Zhang Jilin; Zhang Xinguo; Shi Jianxin; Gong Menglian

2011-01-01

Eu 2+ -doped Sr 3 Al 2 O 6 (Sr 3-x Eu x Al 2 O 6 ) was synthesized by a solid-state reaction under either H 2 and N 2 atmosphere or CO atmosphere. When H 2 was used as the reducing agent, the phosphor exhibited green emission under near UV excitation, while CO was used as the reducing agent, the phosphor mainly showed red emission under blue light excitation. Both emissions belong to the d-f transition of Eu 2+ ion. The relationship between the emission wavelengths and the occupation of Eu 2+ at different crystallographic sites was studied. The preferential substitution of Eu 2+ into different Sr 2+ cites at different reaction periods and the substitution rates under different atmospheres were discussed. Finally, green-emitting and red-emitting LEDs were fabricated by coating the phosphor onto near UV- or blue-emitting InGaN chips. - Highlights: →Sr 3 Al 2 O 6 :Eu 2+ is synthesized by a solid-state reaction under different atmospheres. →Phosphor obtained under H 2 +N 2 atmosphere emits green light under NUV excitation. →Phosphor obtained under CO atmosphere emits red light under blue light excitation. →Different emission wavelengths are due to Eu 2+ in different Sr 2+ sites. →The preferential substitution and the substitution rates of Eu 2+ are discussed.

In this work, [Y3+-Gd3+] and [Mn2+-Ba2+] substitutions were designed in Ba3GdNa(PO4)5F:Eu2+ system, which were marked as BG1-xYxNPF:Eu2+ and B1-yMyGNPF:Eu2+, respectively. It is found that their luminescence properties and thermal stability could be obviously tuned. For BG1-xYxNPF:Eu2+ series, under 365 nm UV light, the emission spectra exhibited a continuous red-shift from 458 nm (x = 0) to 485 nm (x = 1) with the corresponding luminescence varying from blue light to cyan light. For B1-yMyGNPF:Eu2+ series, it was observed the coexistence of blue-green and enhanced red emission of Eu2+ and the appearance of Eu3+ emission when Mn2+ partly substituted Ba2+, resulting in a final white emission. In addition, the thermal stabilities of B1-yMyGNPF:Eu2+ were obviously improved with Mn2+ doping. The corresponding luminescence and thermal stability tuning mechanisms were investigated.

Explaining the present GM business strategy on the EU food market: the gatekeepers' perspective.

Inghelbrecht, Linde; Dessein, Joost; Van Huylenbroeck, Guido

2015-01-25

The use of genetically modified (GM) crops and their applications is partially suppressed in European Union (EU) agriculture, even if one would expect otherwise given their complementarity with the neoliberal and industrialised EU agricultural regime in place. By applying a qualitative content analysis, this paper analyses how food manufacturers and retailers (referred to as gatekeepers in the food industry) explain and defend the exclusion of GM-labelled food products on the EU market. The study design places emphasis on the role of perceptions in the strategic behaviour of gatekeepers and on the role of interaction in this regard, as we assume that the way in which gatekeepers perceive the 'rules of the game' for commercialising GM crop applications on the EU food market will be influenced by their interaction with other agribusiness actors. In a first stage, the analysis determines thematic congruence in the (types of) perceptions that explain an agribusiness actor's overall interpretation of the EU business environment for GM crop applications. This perceived 'structuring arena' (SA) for GM crop applications - as conceptualised within our framework - contains areas of either internal and external tensions, that have a compelling or non-committal influence on the agribusiness actor's interpretation. In a second stage, the analysis particularly defines how gatekeepers in the food industry perceive and experience the SA for GM crop applications on the EU market, and how these perceptual tensions subsequently influence their strategic behaviour for GM-labelled products on the EU market. Finally, we highlight how these perceptions and actions (or inaction) suppress the main changes in practice that are necessary to manage this wicked problem. Copyright © 2014 Elsevier B.V.

Application of US and EU Sustainability Criteria to Analysis of Biofuels-Induced Land Use Change

Directory of Open Access Journals (Sweden)

Krissana Treesilvattanakul

2014-08-01

Full Text Available This research asks and answers a question that had been avoided by all the previous research on biofuels impacts. That is, to what extent are the US and EU biofuels sustainability criteria binding in the sense that if applied, sufficient land would be available to implement the programs? In answering the question, we simulate the global land by agro-ecological zone that would be needed to supply feedstocks for the US and EU biofuel programs using an advanced version of the GTAP-BIO model. Then we estimate the global area of land that would not be available due to sustainability criteria restrictions, again by agro-ecological zone. Finally, we determine the extent to which the US and EU sustainability criteria are binding and find that they are not binding at the biofuel levels currently targeted by the US and EU. In addition, we evaluate the same question, but this time freezing global food consumption, and get the same answer—plenty of land is available to meet the targets and supply food demands.

Can EU Act as a Democracy Promoter? Analysing the Democratization Demand and Supply in Turkey - EU Relations

Directory of Open Access Journals (Sweden)

Çiğdem Üstün

2017-06-01

Full Text Available The EU’s role to assist Turkey in its democratization efforts has been debated during Turkey’s candidacy. However, in the second decade of the 21st century, this role of the EU lost its visibility while Turkey seemed to lose its interest in reform movements. This paper, inspired by Pevehouse, defines the EU as a supplier of democratization mechanisms and Turkey as an actor in need. Although lack of enthusiasm and disengagement have come to characterize Turkey-EU relations, this study aims to demonstrate that there are differences between the governing and the opposition actors’ views on the EU and its role in the democratization of Turkey. Data collected from the speeches of opposition parties’ parliamentarians between 1 January 2011 and 31 August 2016 demonstrates the similarities observed in these parties’ concerns regarding democratic practices and the perception of the EU as an actor strengthening democracy, while indicating that the EU, as a supplier, overlooked their concerns during the process.

We report the change in the valency of Eu-ions in the binary intermetallic cubic compound EuPd{sub 3} induced by La doping at rare-earth sites. Doping of La generates negative chemical pressure in the lattice, resulting in a significant increase of the lattice parameter without altering the simple-cubic structure of the compound. Results of dc-magnetic measurements suggest that this increase in the lattice parameter is associated with the valence transition of Eu-ions from Eu{sup 3+} to a mixed-valent state. As Eu{sup 2+}-ions possess a large magnetic moment, this valence transition significantly modifies the magnetic behavior of the compound. In contrast to introducing boron at the vacant body center site of the unit cell to change the valency of Eu-ions, as in the case of EuPd{sub 3}B, our results suggest it can also be altered by doping a rare-earth ion of larger size at the lattice site of Eu in EuPd{sub 3}.

Highlights: • TBS safety demonstration files. • Safety functions and related design features – detailed TBS components classifications. • Nuclear analyses, radiation shielding and protection. • TBS radiological waste management strategy and categorization. • Selection and definition of reference accidents scenarios and accidents analyses. - Abstract: The European joint undertaking for ITER and the development of fusion energy (‘Fusion for Energy’ – F4E) provides the European contributions to the ITER international fusion energy research project. Among others it includes also the development, design, technological demonstration and implementation of the European test blanket systems (TBS) in ITER. Currently two EU TBS designs are in the phase of conceptual design – helium-cooled lithium-lead (HCLL) and helium-cooled pebble-bed (HCPB). Safety demonstration is an important part of the work devoted to the achievement of the next key project milestone the conceptual design review. The paper reveals the details of the work on EU TBS safety performed in the last couple of years: update of the TBS safety demonstration files; safety functions and related design features; detailed TBS components classifications; nuclear analyses, radiation shielding and protection; TBS radiological waste management strategy and categorization; selection and definition of reference accidents scenarios, and accidents analyses. Finally the authors share the information on on-going and planned future EU TBS safety activities.

Full Text Available Economic policies and decisions on EU association starting with the begginig of 90’s were pseudo-scientific, contradictory, incoherent because those policies have not based themselves on modern and current economic theories elaborated and promoted by the EU. Actuality. The topic is actual from the perspective of the factors’ analysis which were conducting to delay the association process of Moldova to the EU. At the same time, those were increasing instability, disequilibrium in the national economy and raise of social vulnerability and constraint levels which ultimately increased the gap between the national and EU economic development levels. During the period of 2000-2015, the socio-economic policy of the Republic of Moldova is described more as small and fragmented steps on conceiving economic and financial instruments for the integration into the EU which were reflected in the Neighbourhood Partnership and Association Agreement with the EU. These processes conducted for the state incapacity to define its own objectives and social-economic priorities for the association as well as legitimated a continuous stage of transition to the market economy. The scope of the present article is to propose a real change of the development and social-economic association policies for achieving final objective on integration to EU. The proposals would consist in emphasizing and implementation of the EU economic principles reflected in the neoclassic synthesis and neo-conservative theories; the elaboration and implementation of a new Strategy on economic supervision, coordination and anticipation of the economic disequilibrium; achieve economic stability for diminishing the negative effects of the global and regional crisis on national economy and adaptation of the development policies to the national socio-economic conditions. The methods used for the elaboration and achieving the expected results of the study were analysis and synthesis of the

Fighting climate change in the air: lessons from the EU directive on global aviation

2012-01-01

Full Text Available The European Union's (EU decision to include aviation into the Emissions Trade Scheme was heatedly contested. Countries around the world, but mainly the Brazil, Russia, India, China and South Africa group (BRICS and the US, denounced the EU's initiate as illegal and unilateral. Following a decade of frustrated negotiations at the International Civil Aviation Organization (ICAO, this paper interrogates why such measure, in principle climate-friendly, inspired so much global resentment. I argue that concerns with competitiveness and risks of legal inconsistency are important, but insufficient elements to explain the core of the conflict. The paper suggests that the EU was strongly criticized because third countries perceived this action as an imposed solution, which fostered an environment of distrust. Therefore, I claim that the problem has more to do with a normative divide than with a substantive divergence on what should be done regarding aviation emissions. My analysis is informed by the present literature on the links between trade and climate change, but gives particular weight to first-hand information through interviews with key stakeholders. The paper is divided in three parts. First, it presents the scope of the EU directive in historical perspective. Second, it explores the EU's measure through three different angles: legal, economical and political. The final part explores some possible solutions to overcome these divergences.

2009-01-01

Controlled formation of aggregates having organized structure of cube-shaped EuS nanocrystals is reported. The EuS aggregates in liquid media (methanol) were obtained by means of van der Waals interaction between EuS nanocrystals. The packing structure of the EuS aggregates is characterized with transmission electron microscopy (TEM) and small angle X-ray scattering measurements (SAXS). TEM image indicates the EuS nanocrystals form self-aggregated 2D orthogonal lattice structure. The diffraction peak of (111) of SAXS profile shows that the cube-shaped EuS form 3D cubic superlattice. We successfully demonstrated that the aggregates of cube-shaped EuS nanocrystals formed cubic stacking structure.

EU-US economic relations: the TTIP negotiations and its implications

Javier Arregui Moreno

2015-09-01

Full Text Available This article analyses some of the most important arguments for creating a free trade area between the EU and the United States. It also identifies the most conflictive issues in the Transatlantic Trade and Investment Partnership (TTIP and the possible agreements according to the mechanisms and strategies used. The article shows that the TTIP negotiation has sufficient potential to link issues together so that both the EU and the US can exchange positions on various subjects via the logrolling mechanism. Given that the TTIP presents significant potential advantages to both sides and that in this type of negotiation absolute profits tend to prevail, it is feasible that a final agreement will be reached that is accepted by both parties. It would be a new turn of the screw in the process of globalisation, with the aim of preserving the West’s central role on the international stage.

Helena Tendera-Właszczuk

2017-03-01

Full Text Available Objective: The objective of this paper is to evaluate the welfare state models in the EU countries and to start the discussion if the new member states (NMS, i.e. those EU member states that joined the EU in 2004/2007, fit the Sapir typology (Nordic model, Continental model, Anglo-Saxon model, Mediterranean model. The second objective is to examine the labour market situation, reduction of poverty and social inequalities in the EU countries. The third one is to open the issue if the public spending can be managed both justly and effectively. Research Design & Methods: The linear regression function and correlation has been used to present effectiveness of social expenditures to reduce poverty, as well as evidence that public spending can be managed both justly and effectively. Findings: This paper demonstrates more similarities can be drawn across the NMS and the EU-15 than within the NMS and EU-15, respectively. The typology of welfare state models is applied to the NMS and their effectiveness is tested. Accordingly, we classify the Czech Republic, Slovenia and Cyprus as countries of the Nordic model; Hungary, Slovakia and Malta as the Continental model; Lithuania, Latvia and Estonia as the Anglo-Saxon model and, finally, Poland, Croatia, Romania and Bulgaria as the Mediterranean model. Implications & Recommendations: Recent data suggest that the global crisis has caused an increase in the level of poverty and social spending in the EU countries. However, this is just a temporary situation and it does reflect the solutions of models. Contribution & Value Added: The NMS tend to be examined as a separate group of countries that – as the literature suggests – depict different qualities of the welfare models than those pursued in the EU-15.

The syntheses and crystal structures of the two isotypic europium(II) oxide halides Eu{sub 2}OBr{sub 2} and Eu{sub 2}OI{sub 2} are reported. They crystallize orthorhombically in the space group Ibam (Z=4; Eu{sub 2}OBr{sub 2}: a=709.86(5), b=1200.34(9), c=628.71(4) pm; Eu{sub 2}OI{sub 2}: a=739.78(5), b=1295.13(9), c=644.82(4) pm). The unit cell parameters presented here, and thus the interatomic distances of Eu{sub 2}OI{sub 2}, are significantly smaller than the ones reported in the literature, which is explained by the substitution of europium with larger barium cations due to the synthesis route described in the early study. Central building blocks of both crystal structures are trans-edge-connected [OEu{sub 4}]{sup 6+} tetrahedra forming straight {sup 1}{sub ∞}{[OEu"e_4_/_2]"2"+} chains running parallel to the [001] direction. Bundled like a hexagonal rod packing, their interaction is achieved by Br{sup -} or I{sup -} anions for charge compensation.

The expanding EU

DEFF Research Database (Denmark)

Zank, Wolfgang

In this paper I try to explore whether the EU can go on expanding and thereby become culturally ever more diversified, and at the same retain its stability. The answer is, in principle, affirmative. Europe has always been much diversified, and therefore it is not possible to define a European...... identity in terms of particular cultural traditions. However, in spite of their diversity, the EU-member countries are united by their adherence to the principles of democracy, rule by law and human rights. Countries which do not share this basic consensus would not be accepted as members, nor is it likely...... that they would apply for it. An essential part is the willingness of member states to accept a reduction of national sovereignty on some important policy fields. The EU project is basically about lifting the principles of democracy and rule by law on the international level, most and foremost among the member...

Graphical abstract: Three dimensional (3D) architectures YBO 3 :Eu 3+ phosphors were prepared via ionic liquid assisted hydrothermal process. The pH values and ionic liquid play an important role on the morphology of products. Excitation wavelength-dependent luminescent behavior was found in the as-prepared tyre-like YBO 3 :Eu 3+ microspheres. Highlights: • YBO 3 :Eu 3+ phosphors were prepared via ionic liquid assisted hydrothermal process. • pH values and ionic liquid play an important role on the morphology of products. • Excitation wavelength-dependent luminescent behavior was found. -- Abstract: Three dimensional (3D) architectures YBO 3 :Eu 3+ phosphors were prepared via ionic liquid-assisted hydrothermal process and characterized by X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM) and photoluminescence (PL). The pH value and ionic liquid play an important role in the control of morphology of products. By comparing with the corresponding bulk, the tyre-like YBO 3 :5 mol%Eu 3+ microspheres demonstrate a red shift of the charge transfer band (CTB), appearance of a long excitation tail at the long wavelength side of the CTB and high improved chromaticity. Two Eu 3+ environments in the tyre-like sample, namely interior and outside Eu 3+ , were found by selective excitation under the different wavelength light. Finally, fluorescent decays and Judd–Ofelt (J–O) theory were utilized to analyze the local crystal environments around Eu 3+ ions in the tyre-like and bulk phosphors

Patries', applies to a region where nation states are still the determinant factor. The second, 'Fortress Europe', is primarily inward-looking, with a strong drive towards inter-European cooperation and relations. 'Confident Europe' is an active participant in the global international system and practices what it preaches. And lastly, in 'Competitive Europe', market forces effectively deliver and are globally accepted. The main conclusions to be drawn are that the issue for the EU is not energy resources per se, but rather access to them, and that current ambitions at the EU level on climate change adaptation and related energy issues are not likely to be matched by long-term performance in the region. More specifically, in the futures depicted by the four scenarios, the historical downward trend in energy intensity continues in all four storylines; the share of oil in the TPES deceases in all the storylines as well, and even ends up at roughly the same level in all four; coal remains important in the energy mix, largely for electricity generation; gas seems to be the most stable energy source in 2050, no matter what is happening in the world at large; and no physical supply constraints are anticipated. Nuclear energy seems to experience a revival in all the storylines, but with regard to renewable energy sources, there are some notable variations among them. Finally, the new Energy policy for Europe (EPE) presented in early 2007 is assessed from a historical perspective, in the light of the EU's 50-year energy policy quest, and is further analysed in relation to the four 2050 storylines, it is concluded that elements of all four scenarios are found in the EPE, but that the general tendency seems to be moving in the direction of more government intervention in markets instead of less. Meanwhile, for global climate issues the EU seems to be building its policy more on multilateralism and globalism, whereas when seeking energy supply security, nationalism and bilateral or

Single-step linking transition from superdeformed to spherical states in {sup 143}Eu

Energy Technology Data Exchange (ETDEWEB)

1996-12-31

A discrete {gamma}-ray transition which connects the second lowest SD state with a normally deformed one in {sup 143}Eu has been discovered. It has an energy of 3360.6 keV and carries 3.2 % of the full intensity of the SD band. It feeds into a nearly spherical state which is above the I = 35/2{sup +}, E=4947 keV level. The exact placement of the single-step link could, however, not be established due to the especially complicated level scheme in the region of interest. The angular correlation study favours a stretched dipole character for the 3360.6 keV transition. The single-step link agrees well with the previously determined two-step links, both with respect to energy and spin.

Eu and Eu:Yb codoped ZnO nanocrystals embedded in B(2)O(3) glass matrix were synthesized and their structural, optical properties were discussed. On excitation with 532 nm laser radiation intense orange/red emissions from Eu(3+) ions were observed. The fluorescence intensity was found to enhance on annealing. Frequency upconversion emissions from Eu(3+) ions were observed in presence of Yb(3+) ions on excitation with NIR (976 nm) laser. The enhancement in emission intensity was explained and the photo-physics involved is linked with the unique structural properties of the crystallites formed. Ion interactions and the different energy transfer parameters were also calculated. Copyright © 2012 Elsevier B.V. All rights reserved.

Experimental study of concentrational depolarization luminescence (CDL) of phosphate and germanate glasses, containing Eu 3+ ions, has been carried out. On the basis of three-body self-consistent approximation the theory of CDL is conceived, which takes into account Eu-Eu interaction of higher multipolarities. By comparing the theory with the experiment energy transfer radii for Eu-Eu dipole-dipole, dipole-quadrupole and quadrupole-quadrupole interactions are determined. The attempt to discriminate Eu-Eu interaction types in the studied range of Eu 3+ ion concentration change has failed owing to law accuracy of luminescence emittance anisotropy measurement

Three computable general equilibrium models are used to estimate the economic implications of a stylized version of EU climate policy. If implemented at the lowest possible cost, the 20% emissions reduction would lead to a welfare loss of 0.5-2.0% by 2020. Second-best policies increase costs. A policy with two carbon prices (one for the ETS, one for the non-ETS) could increase costs by up to 50%. A policy with 28 carbon prices (one for the ETS, one each for each Member State) could increase costs by another 40%. The renewables standard could raise the costs of emissions reduction by 90%. Overall, the inefficiencies in policy lead to a cost that is 100-125% too high. The models differ greatly in the detail of their results. The ETS/non-ETS split may have a negligible impact on welfare, while the renewables standard may even improve welfare. The models agree, however, that the distortions introduced by total EU package imply a substantial welfare loss over and above the costs needed to meet the climate target. The marginal, total and excess costs reported here are notably higher than those in the impact assessment of the European Commission. (author)

Should the EU climate policy framework be reformed?

Directory of Open Access Journals (Sweden)

David ELLISON

2011-12-01

Full Text Available Though to-date the European Union (EU has played the most significant leadership role in international negotiations to reduce greenhouse gas (GHG emissions, the emission-reducing performance of individual EU Member states has for many been less than stellar. Several EU15 Member states continue to raise rather than lower emissions. Analysing the most successful policy instruments, this paper argues EU policy efforts could benefit from three important innovations. The following strategies – the adoption of an EU-wide FIT (feed-in tariff, an EU-wide carbon tax and more flexibility in the trading of carbon credits – could significantly improve emission reductions, their relative cost-efficiency and spread burden-sharing more evenly across technologies and Member states. This raises important questions, both about the effectiveness of EU and Kyoto-style commitments, as well as the EU Emission Trading Scheme (ETS. The commitment strategy, and in particular the EU ETS mechanism, have had the smallest impact on emission reductions. The proposed set of strategies could make a far greater contribution to future EU efforts and potentially lock in the impressive progress already made. Such a policy shift, if successful, would also greatly enhance the EU’s already significant credibility and bargaining power in international climate negotiations.

We have studied the valence behavior of rare-earth ions, in particular Eu-ions, in a cubic intermetallic compound Ce{sub 0.5}Eu{sub 0.5}Pd{sub 3}B{sub 0.5} which is a homogeneous solid solution of two mixed-valent compounds CePd{sub 3} and EuPd{sub 3}B. Results of {sup 151}Eu Moessbauer spectroscopic measurements show that two different valence states, i.e., divalent- and trivalent-like states of Eu-ions exist in the compound. The possible reason for the observed heterogeneous valency vis-a-vis the variation in the chemical environment and the number of nearest-neighbor B atoms surrounding the Eu-ions has been discussed. Our results demonstrate that B incorporation in such Eu-based cubic intermetallic compounds leads to a situation where heterogeneous-valence state of Eu-ions is an energetically favorable ground state. - Highlights: > Intermetallic compound Ce{sub 0.5}Eu{sub 0.5}Pd{sub 3}B{sub 0.5} crystallizes in a single phase. > Eu-ions in Ce{sub 0.5}Eu{sub 0.5}Pd{sub 3}B{sub 0.5} are charge-ordered compared to +2.3 valency in Ce{sub 0.5}Eu{sub 0.5}Pd{sub 3}. > B incorporation makes charge-ordered state of Eu-ions energetically more favorable. > Nearest-neighbor chemical environment affects the Eu valency.

They crystallize with the EuAuGe type structure, space group Imm2. The four structures were refined from single-crystal X-ray data. The silver and indium atoms build up orthorhombically distorted, puckered Ag{sub 3}In{sub 3} hexagons, which are stacked in AA' sequence, leading to direct Ag-Ag and In-In interlayer bonding (e.g. 303 and 304 pm in CaAgIn). Temperature dependent magnetic susceptibility measurements show a magnetic moment of 7.40(1) μ{sub B} per europium atom. EuAgIn orders antiferromagnetically at 5.7(5) K. The divalent nature of europium is also evident from {sup 151}Eu Moessbauer spectra: δ = -10.50(1) mm.s{sup -1} at 78 K. (copyright 2017 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim)

We study the valence band of Eu-intercalated C60 by synchrotron radiation photoelectron spectroscopy to un-derstand the ferromagnetism (FM) and the giant magnetoresistance (GMR) of Eu6C60. The results reveal the semiconducting property and the remarkable 5d6s-π hybridization. Eu-C60 bonding has both ionic and covalent contributions. No more than half the 5d6s electrons transfer from Eu to the LUMO derived band of C60, and the LUMO+1 derived band is not filled. The remaining valence electrons of Eu, together with some π (LUMO, HOMO and HOMO-1) electrons, constitute the covalent bond. The electronic structure implies that the magnetic coupling in Eu6C60 should be through the intra-atomic f-sd exchange and the medium of the π electrons. The possibility of the GMR being tunnelling magnetoresistance is ruled out.

The novel polyphosphide, EuP/sub 7/, was prepared under controlled conditions by reaction of the elements in salt melts at 750-800 K. EuP/sub 7/ forms black prismatic crystals not attacked by dilute mineral acids and bases. The thermal decomposition yields EuP/sub 3/ at 700 K and in further steps EuP/sub 2/, Eu/sub 3/P/sub 4/ and EuP, respectively. According to the crystal structure as well as the electrical, optical and magnetic properties, EuP/sub 7/ is a semiconductor (Esub(G) = 0.9 eV; Esub(G) (vert) = 1.1 eV) with divalent europium (..mu.. = 7.55 B.M.). The compound crystallizes in the monoclinic space group P 2/sub 1//n with a = 1148.8(7) pm, b = 570.0(3) pm, c = 1061.0(6) pm, and ..beta.. = 106.08/sup 0/(5); (X-ray diffraction data; 1479 hkl; R = 0.031). The P-atoms are connected ((P-P) = 218.0-223.5 pm) to a 2-dimensional infinite polyanionic structure 2sub(infinity)(P/sub 7//sup 2 -/) with homonuclear 3-bonded and 2-bonded P-atoms in the ratio 5 : 2. The polyanionic network contains P/sub 6/-rings (chair conformation) as well as P/sub 8/-rings and P/sub 10/-rings. The Eu-atoms are bonded to 9 P-atoms (1,4,4-polyhedra) with bond distances ranging from 306.6 to 326.6 pm. The Eu-atoms complete the tetrahedral environment of the P-atoms.

The emission limits for diesel locomotives inside the European Union are included within the scope of Directive 97/68/EC, which is sometimes referred to as the ''non-road directive''. The pollutants limited by it are NO{sub x}, particulates, CO and HCs. The aim, through the directive, is to reduce railway emissions by a factor of ten by the year 2020. The EU stage IIIB standard is due to take effect on 1 January 2012. This envisages a further drastic reduction in limit values compared with EU stage IIIA, which is applicable today. For diesel locomotives, EU stage IIIA only came into force as recently as 2009. The manufacturers of engines and locomotives are thus having to face up to the huge challenge of getting the technologies needed for EU stage IIIB ready for the production line within a period of only three years. MTU has succeeded in developing engines for diesel locomotives that comply with the EU stage IIIB emission standard, which appreciably lower emissions compared with engines satisfying EU stage IIIA, thanks to the incorporation of the most modern technologies available, and has even gone as far as preparing them for the EU stage IV, the next one to come into force.

By means of pulsed laser deposition, polycrystalline thin films of GaN doped with Eu{sup 3+} were grown on sapphire. The PLD target was formed in three steps. First, stoichiometric amounts of Ga{sub 2}O{sub 3} and Eu{sub 2}O{sub 3} were dissolved in nitric acid, which produces Ga{sub (1-x)}Eu{sub x} (NO{sub 3}){sub 3}. Next, the nitrates were oxidized in a tubular furnace with O{sub 2} flow forming Ga{sub 2(1-x)}Eu{sub 2x}O{sub 3}. Finally, the oxide powder was flushed with anhydrous ammonia to produce the desired nitride product: Ga{sub (1-x)}Eu{sub x}N. Film growth was done in a stainless steel vacuum chamber partially filled with N{sub 2} (400 mTorr). For the deposit, the 3{sup rd} harmonic of a Nd:YAG laser ({lambda}=355 nm) was focused on the surface of the target. After deposition, annealing in NH{sub 3} was required to produce films with pure GaN hexagonal phase. The luminescence of the film was characterized by photo- and cathodoluminescence. In addition, the chemical and structural properties were analyzed by X-ray diffraction, scanning electron microscopy and energy dispersive spectroscopy. (copyright 2008 WILEY-VCH Verlag GmbH and Co.

Effective photoswitchable europium sulfide nanocrystals with gold nanoparticles using dithiol (DDT: 1,10-decanedithiol) joint molecules, EuS-Au nanosystems, are demonstrated. The TEM image indicates the formation of EuS-Au nanosystems composed of cube-shaped EuS nanocrystals and spherical Au nanoparticles. Under visible-light irradiation, a drastic change of absorption band of EuS-Au nanosystems at around 600 nm was observed. The Faraday effects of EuS-Au nanosystems were estimated using magnetic circular dichroism (MCD) measurements. The effective change of the MCD spectra of EuS-Au nanosystems under visible-light irradiation was successfully observed at around 670 nm for the first time. The effective reversible changes in MCD spectra with the alternative irradiation cycles of visible light (>440 nm) and dark are also presented. The decrease rate of rotation angle at 670 nm of EuS-Au nanosystems is larger than that of absorbance. These results indicate that the effective change of MCD spectra of EuS-Au nanosystems would be dominated not only by a drastic change of absorption band related to enhanced LSPR of Au nanoparticles but also by specific interaction between EuS and Au in nanosystem under irradiation.

Within the framework of the research undertaken by the French Atomic Energy Commission on transmutation of long-lived radionuclides, targets of highly enriched actinides and fission products were irradiated in the fast neutron reactor Phenix. Precise and accurate measurements of the isotopic and elemental composition of the enriched elements are therefore required. In order to obtain the uncertainties of several per mil and to reduce handling time and exposure to analyst on radioactive material, the on-line coupling of ion exchange chromatography with quadrupole inductively coupled plasma mass spectrometry has been associated with the technique of the double spike isotope dilution. We present in this paper the results obtained on an irradiated sample of Europium oxide powder (enriched at 99.13% in 153 Eu). After irradiation of around 5 mg of Eu 2 O 3 powder the theoretical calculations predict the formation of several micrograms of gadolinium and samarium isotopes. In relation to the very high activity of the sample after irradiation and the very low quantity of Sm formed, the on-line ion exchange chromatography separation of Gd, Sm and Eu before Sm isotope ratio measurements has been developed for the quantification of the 152 Sm/ 153 Eu ratio. These on-line measurements were associated with the double spike isotope dilution technique after calibration of a 147 Sm/ 151 Eu spike solution. The external reproducibility of Sm isotopic ratios was determined to be around 0.5% (2 σ) resulting in a final uncertainty on the 152 Sm/ 153 Eu ratio of around 1% (2 σ). These on-line measurements present therefore a robust and high-throughput alternative to the thermal-ionisation mass spectrometry technique used so far in combination with off-line chromatographic separation, particularly in nuclear applications where characterisation of high activity sample solutions is required.

A series of new emission-tunable phosphors Bi{sub 0.95−y}PO{sub 4}:0.05Tb{sup 3+},yEu{sup 3+} were synthesized by a facile hydrothermal method with surfactant-free environment. XRD results indicated that phosphors possess the standard BiPO{sub 4} monoclinic structure. From the luminescence spectra and decay curves, the energy transfer from Tb{sup 3+} to Eu{sup 3+} was confirmed. The efficient Tb{sup 3+} to Eu{sup 3+} energy transfer can be used to tune the emission color from green, yellow to orange by simply changing the concentration of europium, making the materials have potential applications in three-color-based displays and white light illumination. Finally, the energy transfer mechanism between Tb{sup 3+} and Eu{sup 3+} was demonstrated to be the electric quadrupole–quadrupole interaction based on Dexter's energy transfer formula and the Inokuti–Hirayama model. - Highlights: • BiPO{sub 4}: Tb{sup 3+}, Eu{sup 3+} phosphor was synthesized by a facile hydrothermal method. • Energy transfer from Tb{sup 3+} to Eu{sup 3+} in BiPO{sub 4} was firstly studied. • The Q–Q interaction is the main mechanism for energy transfer from Tb{sup 3+} to Eu{sup 3+}. • BiPO{sub 4}: Tb{sup 3+}, Eu{sup 3+} has potential applications in white LEDs and display devices.

Highlights: • Eu incorporated ZnO thin films were grown by sol–gel spin coating. • The influence of Eu contribution on features of ZnO was investigated. • Al/ZnO:Eu/p-Si heterojunction diodes were also fabricated. • The diode parameters were calculated from I–V measurements. - Abstract: In present work, the pure and europium (Eu) incorporated zinc oxide (ZnO) thin films were deposited with sol-gel spin coating by using zinc acetate dehydrate and Eu (III) chloride salts. The coated films were examined by means of XRD, AFM and UV/VIS spectrophotometer. The ZnO hexagonal wurtzite nanoparticles with (002) preferential direction were observed for all films. The values of crystallite size, micro-strain and surface roughness continuously increased from 21 nm, 1.10 × 10{sup −3} and 2.43 nm to the values of 35.56 nm, 1.98 × 10{sup −3} and 28.99 nm with Eu doping, respectively. The optical band gap value of the pure ZnO initially increased from 3.296 eV to 3.328 eV with Eu doping up to 2 at.% doping level, then it started to decrease with more Eu content. The electrical features of Al/n-ZnO:Eu/p-Si heterojunction diodes were inquired by current-voltage (I–V) measurements at the room temperature.

2015-01-01

This study investigates CO 2 emission reduction within the EU resulting from the Emissions Trading Scheme (ETS) up to 2030. This is performed by constructing a baseline scenario without the ETS and assessing the impacts of the ETS, as currently designed. The results indicate that the ETS will start to impact emissions primarily after 2025 due to the prevalence of a sizable allowance surplus. The impact of approved (i.e. back-loading and 2.2% linear reduction factor (LRF)) and proposed (i.e. market stability reserve (MSR)) policy interventions and the inclusion of aviation, could accelerate the exhaustion of surplus and increase emission reductions during the investigated period. However, these measures would be insufficient to restore the scarcity of allowances and the corresponding carbon price before the start of ETS Phase IV, and the effectiveness of EU-internal abatement cannot be guaranteed until 2023. The effectiveness could be further reduced in the case of the economic shocks or the exclusion of international aviation. To restore the scarcity of allowances, other reform options are necessary. This paper extends the reasoning for the early removal of the back-loaded 900 Mtonne allowances by 2020 and broadening the scope of ETS to other sectors with potential high demand for allowances. - Highlights: • Quantification of CO 2 emission abatement in the EU resulting from the ETS up to 2030. • The impact of policy interventions and the inclusion of aviation is quantified. • The effectiveness of EU ETS in EU-internal abatement is limited until 2023

New reddish-orange and greenish-yellow light emitting phosphors: Eu3+ and Tb3+/Eu3+ in sodium germanate glass

A spectroscopic analysis of sodium germanate glasses activated with Eu 3+ , Tb 3+ and Eu 3+ /Tb 3+ is performed from their photoluminescence spectra and decay times. In the Eu 3+ -singly doped glass reddish-orange light emission, with x=0.64 and y=0.35 CIE1931 chromaticity coordinates, is obtained upon Eu 3+ excitation at 393 nm. Such chromaticity coordinates are close to those (0.67, 0.33) proposed by the National Television Standard Committee for the red phosphor. When the sodium germanate glass is co-doped with Tb 3+ and Eu 3+ greenish-yellow light emission, with (0.41, 0.46) CIE1931 chromaticity coordinates, is obtained upon Tb 3+ excitation at 344 nm. Such greenish-yellow luminescence is due mainly to the terbium 5 D 4 → 7 F 6,5 and europium 5 D 0 → 7 F 1,2 emissions, Eu 3+ being sensitized by Tb 3+ through a non-radiative energy transfer. The non-radiative nature of this energy transfer is inferred from the increase in the decay rate of the Tb 3+ emission when the glass is co-doped with Eu 3+ . From an analysis of the Tb 3+ emission decay time curves it is inferred that such energy transfer might take place between Tb 3+ and Eu 3+ clusters through a short-range interaction mechanism. - Highlights: • Sodium germanate glasses are optically activated with Eu 3+ (GNE) and Tb 3+ /Eu 3+ (GNTE). • Reddish-orange light (0.64, 0.35) is generated by GNE pumped with 393 nm light. • Greenish-yellow light (0.41, 0.46) is generated by GNTE pumped with 344 nm light. • Non-radiative energy transfer Tb 3+ →Eu 3+ takes place in GNTE

EU trade in the time of financial crisis

Fojtíková, L.

2010-12-01

Full Text Available The paper is focused on the European Union (EU trade and trade policy in the time of global financial and economic crisis. The analysis of the EU exports and imports points out that the financial crisis has had a negative impact on the intra as well as on the extra-EU trade in the period 2007-2009, but differences among the EU member states have existed. Although the EU tries to support trade development in the world and remove barriers to trade, some protectionist tendencies were recorded in the time of the economic crisis. The last part of the paper gives emphasis to the EU trade policy and some trade measures which have been taken in the EU and its member states to support trade development or vice versa, to protect domestic industries. The results of the analysis show that, although some protectionist tendencies have been recorded both in extra and intra-EU trade, trade relations which are provided among member states are of significant importance all the time.

EU import restrictions on genetically modified feeds: impacts on Spanish, EU and global livestock sectors

Energy Technology Data Exchange (ETDEWEB)

Philippidis, G.

2010-07-01

Over the last decade, much controversy has surrounded the usage of genetically modified organism (GMO) technology in commercial agriculture. More specifically, it is feared that GMOs may introduce new allergens into the food chain or contribute to antibiotic resistance. At the current time, the European Union (EU) adopts a zero tolerance policy toward non-approved GMO imports, whilst the approval process has not kept pace with the proliferation of new GMO varieties. In the EU livestock sectors, this apparent mis-match threatens to interrupt supplies of high protein feed inputs (e.g., soy meal) from countries with more relaxed regulations regarding GMOs. Employing a well known multi-region computable general equilibrium framework, this study quantitatively assesses the impact of a hypothetical EU import ban on unapproved GMO varieties of soybean and maize imports on livestock, meat and dairy sectors. The model code is heavily modified to improve the characterisation of the agricultural sectors and land usage, whilst a realistic baseline is employed to update the global database to 2008, the year the hypothetical ban is implemented. In the worst case scenario, there are significant competitive losses in EU livestock, meat and dairy sectors. In Spain, the negative impacts are particularly pronounced given the importance of pig production in agriculture. In contrast, all non-EU regions trade balances improve, with notable trade gains in the USA and Brazil. To conclude, the EU must urgently find a long term strategy for GMOs if it is to reconcile political expediency with pragmatic economic concerns. (Author) 21 refs.

Full Text Available The impact of the international economic crisis on new EU member states has proven to be more severe than the first estimates of the economic analysts. The situation is different for each Member State, the nature and the dimension of the challenges faced are not identical, and the pace of reform is not the same. The economic crisis has prompted intense and sustained action by the EU's national governments, the European Central Bank and the Commission. All have been working closely together to support growth and employment, ensure financial stability, and put in place a better governance system for the future. Sustainable development in the future is the common responsibility of all Member States and EU institutions, because our economies are closely interlinked, and the EU economic governance now reconfigured to provide more effective responses at the policy level, to give a good reaction to the present and the future challenges.

2017-08-01

The objective of this study is to understand light emission characteristics of fracto-mechanoluminescent (FML) europium tetrakis(dibenzoylmethide)-triethylammonium (EuD4TEA) crystals under high strain-rate compressive loading. As a sensing material that can play a pivotal role for the self-powered impact sensor technology, it is important to understand transformative light emission characteristics of the FML EuD4TEA crystals under high strain-rate compressive loading. First, EuD4TEA crystals were synthesized and embedded into polydimethylsiloxane (PDMS) elastomer to fabricate EuD4TEA-PDMS composite test specimens. Second, the prepared EuD4TEA-PDMS composites were tested using the modified Kolsky bar setup equipped with a high-speed camera. Third, FML light emission was captured to yield 12 bit grayscale video footage, which was processed to quantify the FML light emission. Finally, quantitative parameters were generated by taking into account pixel values and population of pixels of the 12 bit grayscale images to represent FML light intensity. The FML light intensity was correlated with high strain-rate compressive strain and strain rate to understand the FML light emission characteristics under high strain-rate compressive loading that can result from impact occurrences.

Effect of Eu magnetism on the electronic properties of the candidate Dirac material EuMnBi2

Science.gov (United States)

May, Andrew F.; McGuire, Michael A.; Sales, Brian C.

2014-08-01

The crystal structure and physical properties of the layered material EuMnBi2 have been characterized by measurements on single crystals. EuMnBi2 is isostructural with the Dirac material SrMnBi2 based on single-crystal x-ray diffraction, crystallizing in the I4/mmm space group (No. 139). Magnetic susceptibility measurements suggest antiferromagnetic (AFM) ordering of moments on divalent Eu ions near TN=22 K. For low fields, the ordered Eu moments are aligned along the c axis, and a spin flop is observed near 5.4 T at 5 K. The moment is not saturated in an applied field of 13 T at 5 K, which is uncommon for compounds containing Eu2+. The magnetic behavior suggests an anisotropy enhancement via interaction between Eu and the Mn moments that appear to be ordered antiferromagnetically below ≈310 K. A large increase in the magnetoresistance is observed across the spin flop, with absolute magnetoresistance reaching ≈650% at 5 K and 12 T. Hall effect measurements reveal a decrease in the carrier density below TN, which implies a manipulation of the Fermi surface by magnetism on the sites surrounding the Bi square nets that lead to Dirac cones in this family of materials.

The Location of ICT activities in EU regions. Implications for regional policies

Directory of Open Access Journals (Sweden)

Salvador Barrios

2008-11-01

Full Text Available The location of ICT producing industries does matter for global competitivenessand long-run growth potential. For instance, the differing contribution ofICT to economic growth between the US and the EU is often mentioned as one of themain cause explaining the diverging growth performance of these two areas since themid-1990s. In turn, since the mid-1990s, countries with especially dynamic economicgrowth have tended to be highly specialized in ICT-producing and ICT-using industries,see van Ark and Inkaar (2005. More generally, ICT producing sectors, tendto promote technological change and innovative capability which are seen to be at thecore of economic growth and competitiveness. When considering the EU economy,ICT industries appear to be concentrated in a limited number of regions, see Koski etal. (2002 for empirical evidence. Afirst objective of the present paper is to documentthe location of ICT producing industries in European regions in order to map existingEU clusters as well as to analyze recent changes in these industries using recent dataon employment and firm location, especially in relation to the EU enlargement thathas taken place in May 2004. The location of the ICT-producing sectors is not the endof the story however. A crucial aspect concerns the nature of activities that are beingundertaken in different regions. Importantly, ICT industries do have different characteristicsin terms of human capital, skill requirement, and knowledge content. In particular,because of the positive association between human capital, knowledge andlong-run growth, it is important to analyze to what extent EU regional ICT clustersdiffer in according to these characteristics. The second question addressed in the paperconcerns the nature of ICT activities undertaken in EU regions. Finally, the paperprovides econometric estimates of the location of firms in ICT industries across EUregions. The paper considers more specifically the case of multinationals�

Blue emission in photoluminescence spectra of the red phosphor CaAlSiN3:Eu2+ at low Eu2+ concentration

Suda, Yoriko; Kamigaki, Yoshiaki; Yamamoto, Hajime

2018-04-01

In red phosphor CaAlSiN3:Eu2+, unintentional blue emission occurs with increasing intensity at low Eu2+ concentrations and also at low measurement temperatures. Time-resolved photoluminescence measurements were used to confirm the decrease in red emission and increase in blue emission with the decreasing Eu2+ concentration. The peak timing of blue emission occurred faster than that of red emission, and long lasting luminescence of red emission was observed as well as that of blue emission. The Eu2+ concentration dependences of the red and blue emissions were similar to those of the g values 4.75 (Eu2+) and 2.0025 (nitrogen vacancies), respectively, which were observed from electron spin resonance (ESR) measurements. The origin of the blue emission is proposed to be nitrogen vacancy defects, which had about the same ESR signal intensity as that of Eu2+ ions in CaAlSiN3:Eu2+ containing 0.01 at. % Eu2+. The possibility of red emission also arising from excited electron tunneling or thermal pathways via nitrogen vacancies is discussed. Long lasting red emission was observed, which is proposed to involve trapped electrons remaining at nitrogen vacancies, yielding blue emission and inducing red emission from Eu2+ ions.

Fighting windmills? EU industrial interest and global climate negotiations

International Nuclear Information System (INIS)

Steiner Brand, U.; Tinggaard Svendsen, G.

2003-01-01

Why has the EU been so eager to continue the climate negotiations? Can it be solely attributed to the EU feeling morally obliged to be the main initiator of continued progress on the climate change negotiations, or can industrial interests in the EU, at least partly, explain the behaviour of the EU? We suggest that the EU has a rational economic interest in forcing the technological development of renewable energy sources to get a fast-mover advantage, which will only pay if a sufficient number of countries implement sufficiently stringent GHG reductions. The Kyoto Protocol, which imposes binding reductions on 38 OECD countries, implies that, as a first-mover, the EU will be to sell the necessary new renewable technologies, most prominently wind mills, to other countries, when they ratify and implement the Kyoto target levels. In the latest EU proposal made in Johannesburg, the EU pushed for setting a target of 15% of all energy to come from sources such as windmills, solar panels and waves by 2015. Such a target would further the EU's interests globally, and could explain, in economic terms, why the EU eagerly promotes GHG trade at a global level whereas the US has left the Kyoto agreement to save the import costs of buying the EU's renewable systems.

On January 23, 2008, the European Commission presented proposals in the form of a directive in an effort to give more specific shape to the objective adopted in the spring, i.e. to increase to 20% by 2020 the share of renewable energies in energy consumption in the Community. The proposal was to include legally binding goals for the overall share of renewable energy sources and the share of biofuels in the transport sector. The proposed directive on 'promoting the use of energy from renewable sources' calls upon each member state to ensure that its share of energy from renewable sources in the total energy consumption in 2020 at least corresponds to the target mentioned in Annex I Part A. In addition to the targets, the EU Commission charted a tentative course towards a minimum increase in the share of renewable energies in the period between 2011 and 2020. Finally, the member states are obliged to adopt national action plans. Unfortunately, the EU is missing an important target in its proposed directive: It should establish a framework for harmonized conditions promoting the use of renewable energies. One aspect to be welcomed is the introduction of a system of certificates of origin. It represents the entry, in principle, into a trading system with certificates of origin. The Green Package incorporates a wealth of new approaches. They will have to be tested and, if necessary, supplemented. Something else is evident, however: The directive established the foundations of a vast number of new regulations and red tape. (orig.)

Contract theory and EU Contract Law

OpenAIRE

Hesselink, M.W.; Twigg-Flesner, C.

2016-01-01

This paper explores the relationship between contract theory and European contract law. In particular, it confronts the leading contract law theories with the main characteristics of EU contract law. The conclusion is that the two do not match well. In particular, monist normative contract theories are largely irreconcilable with the contract law of the EU. The paper further addresses the main implications of this mismatch, both for contract theory and for EU contract law. It suggests that in...

Modelling Eu(III) speciation in a Eu(III)/PAHA/α-Al2O3 ternary system

International Nuclear Information System (INIS)

Janot, Noemie; Reiller, Pascal E.; Benedetti, Marc F.

2013-01-01

In this work, modelling of Eu(III) speciation in a ternary system, i.e., in presence of purified Aldrich humic acid (PAHA) and α-Al 2 O 3 , is presented. First, the mineral surface charge is measured by potentiometric titrations and then described using the CD-MUSIC model. This model is also used to describe Eu(III) binding to the α-Al 2 O 3 surface at different pH values, ionic strength and mineral concentrations. Time resolved luminescence spectroscopy (TRLS) is then used to study the binding of Eu(III) to PAHA at pH 4 with different humic acid concentrations. The spectra are used to calculate a spectroscopic 'titration curve', used to determine Eu(III)/PAHA binding parameters in the NICA-Donnan model. Following a previous study (Janot et al., Water Res. 46, 731-740), modelling of the ternary system is based upon the definition of two PAHA pools where one fraction remains in solution and the other is adsorbed onto the mineral surface, with each possessing different proton and metal binding parameters. The modification of protonation behaviour for both fractions is examined using spectrophotometric titrations of the non adsorbed PAHA fraction at different organic/mineral ratios. These data are then used to describe Eu(III) interactions in the ternary system: Eu(III) re-partitioning in the ternary system is calculated for different pH, ionic strength and PAHA concentrations, and results are compared to experimental observations. The model is in good agreement with experimental data, except at high PAHA fractionation rates. Results show that organic complexation dominates over a large pH range, with the predominant species existing as the surface-bound fraction. Above pH 8, Eu(III) seems to be mostly complexed to the mineral surface, which is in agreement with previous spectroscopic observations (Janot et al., Environ. Sci. Technol. 45, 3224-3230).

Arsene, Carmen

2009-01-01

The irradiated graphite in Romania is mainly generated in the thermal columns of TRIGA and WWER-S research reactors (about 9 tones). It was found that the radionuclide content of the graphite irradiated in the TRIGA research reactor is mainly due to C-14 (103 Bq/g), Eu-152 (600-700 Bq/g) and Co-60 (130-150 Bq/g) and low amounts of Eu-154 and Cs-137, depending on location in the thermal column and on irradiation history. In order to minimize the waste inventory and volume in view of their final disposal, in the present paper we show the results of experiments performed for developing and optimizing methods for the chemical decontamination of the irradiated graphite. These procedures are based on strong alkaline solutions for Eu-152 and strong acid solutions for Co-60. The influence of the process parameters on the decontamination factor is investigated.

Succession of States in the EU

Directory of Open Access Journals (Sweden)

Mario Martini

2014-09-01

Full Text Available A specter is haunting Europe – the specter of separatism. Scotland, Catalonia, Flanders, South Tyrol – all these regions have separatist movements pursuing independence from their current National State. The breakup of an EU Member State no longer seems impossible. To date, it is unclear what impact this would have on the EU membership of the new entities (with consequences for the character of citizenship, voting rights in the council, number of MEPs etc. that emerge from the old States. The common rules of Public International Law governing the succession of States are insufficient in the case of a succession of States in the EU. Although the Treaties do not provide for such a situation and the past 60 years of European history offer only a few and not really persuasive precedents, the nature of the EU as a joint association of sovereign States (“Staatenverbund” demands a special approach: A separated State will neither be automatically excluded from the EU nor will it automatically become a new Member State.

Energy transfer mechanism in CsI:Eu crystal

2014-01-01

This paper studies the scintillation process in CsI:Eu crystal exposed to the pulse electron irradiation (E=0.25 MeV, t 1/2 =15 ns and W=0.003 J/cm 2 ). It has been proved that the energy transfer from the lattice to Eu 2+ ions in CsI:Eu occurs through the re-absorption of STE emission. The proposed model rests on the following experimental facts: (1) the activator emission at 2.68 eV rises gradually after the decay of the excitation pulse even at temperature lower than 90 K when V k centers are immobile; (2) the rise time of 2.68 eV emission and the decay time of STE emission have the same temperature dependences at T=78–300 K; (3) the excitation spectrum of 2.68 eV emission overlaps the emission spectrum of STE. -- Highlights: • The scintillation process in CsI:Eu was studied under pulsed electron irradiation. • A model of the energy transfer from the lattice to Eu 2+ ions in CsI:Eu was proposed. • Eu 2+ ions in CsI:Eu reabsorb the π-emission of self-trapped excitons

The EU electricity production structure requires a differentiated energy policy; Die Stromerzeugungsstruktur der EU erfordert eine differenzierte Energiepolitik

For the electricity production of the EU there are differentiated structures which are based on different natural conditions, political decisions and investments of past decades. It has long been struggled committed to the ''one and correct'' energy policy. But precisely because of the differences in the individual countries, a unified energy and climate policy for the EU is not the right way. Diversity is a strength, which quite the EU Commission considered. Increased understanding of the specifics in other countries should just apply the German politics and the public that all too often judges from their own perspective. [German] Bei der Stromerzeugung in der EU bestehen differenzierte Strukturen, die auf unterschiedlichen natuerlichen Gegebenheiten, politischen Entscheidungen und Investitionen vergangener Jahrzehnte beruhen. Seit langem wird engagiert um die ''eine und richtige'' Energiepolitik gerungen. Doch gerade wegen der Unterschiede in den einzelnen Laendern kann eine vereinheitlichte Energie- und Klimapolitik fuer die EU nicht der richtige Weg sein. Vielfalt ist eine Staerke, was die EU-Kommission durchaus beruecksichtigt. Mehr Verstaendnis fuer die Spezifika in anderen Laendern sollte daher gerade die deutsche Politik und Oeffentlichkeit aufbringen, die allzu oft aus eigener Perspektive heraus urteilt.

The evolution of emissions trading in the EU. Tensions between national trading schemes and the proposed EU directive

Boemare, Catherine; Quirion, Philippe; Sorrell, Steve

2003-12-01

The EU is pioneering the development of greenhouse gas emissions trading, but there is a tension between the 'top-down' and 'bottom-up' evolution of trading schemes. While the Commission is introducing a European emissions trading scheme (EU ETS) in 2005, several member states have already introduced negotiated agreements that include trading arrangements. Typically, these national schemes have a wider scope than the proposed EU directive and allow firms to use relative rather than absolute targets. The coexistence of 'top-down' and 'bottom-up' trading schemes may create some complex problems of policy interaction. This paper explores the potential interactions between the EU ETS and the negotiated agreements in France and UK and uses these to illustrate some important generic issues. The paper first describes the proposed EU directive, outlines the UK and French policies and compares their main features to the EU ETS. It then discusses how the national and European policies may interact in practice. Four issues are highlighted, namely, double regulation, double counting of emission reductions, equivalence of effort and linking trading schemes. The paper concludes with some recommendations for the future development of UK and French climate policy

Europe, the EU and its 2050 Energy Storylines

societal climate prevailing in the region. The first, 'l'Europe des Patries', applies to a region where nation states are still the determinant factor. The second, 'Fortress Europe', is primarily inward-looking, with a strong drive towards inter-European cooperation and relations. 'Confident Europe' is an active participant in the global international system and practices what it preaches. And lastly, in 'Competitive Europe', market forces effectively deliver and are globally accepted. The main conclusions to be drawn are that the issue for the EU is not energy resources per se, but rather access to them, and that current ambitions at the EU level on climate change adaptation and related energy issues are not likely to be matched by long-term performance in the region. More specifically, in the futures depicted by the four scenarios, the historical downward trend in energy intensity continues in all four storylines; the share of oil in the TPES deceases in all the storylines as well, and even ends up at roughly the same level in all four; coal remains important in the energy mix, largely for electricity generation; gas seems to be the most stable energy source in 2050, no matter what is happening in the world at large; and no physical supply constraints are anticipated. Nuclear energy seems to experience a revival in all the storylines, but with regard to renewable energy sources, there are some notable variations among them. Finally, the new Energy policy for Europe (EPE) presented in early 2007 is assessed from a historical perspective, in the light of the EU's 50-year energy policy quest, and is further analysed in relation to the four 2050 storylines, it is concluded that elements of all four scenarios are found in the EPE, but that the general tendency seems to be moving in the direction of more government intervention in markets instead of less. Meanwhile, for global climate issues the EU seems to be building its

Electronic transport through EuO spin-filter tunnel junctions

KAUST Repository

Jutong, Nuttachai

2012-11-12

Epitaxial spin-filter tunnel junctions based on the ferromagnetic semiconductor europium monoxide (EuO) are investigated by means of density functional theory. In particular, we focus on the spin transport properties of Cu(100)/EuO(100)/Cu(100) junctions. The dependence of the transmission coefficient and the current-voltage curves on the interface spacing and EuO thickness is explained in terms of the EuO density of states and the complex band structure. Furthermore, we also discuss the relation between the spin transport properties and the Cu-EuO interface geometry. The level alignment of the junction is sensitively affected by the interface spacing, since this determines the charge transfer between EuO and the Cu electrodes. Our calculations indicate that EuO epitaxially grown on Cu can act as a perfect spin filter, with a spin polarization of the current close to 100%, and with both the Eu-5d conduction-band and the Eu-4f valence-band states contributing to the coherent transport. For epitaxial EuO on Cu, a symmetry filtering is observed, with the Δ1 states dominating the transmission. This leads to a transport gap larger than the fundamental EuO band gap. Importantly, the high spin polarization of the current is preserved up to large bias voltages.

Correlation theory applied to the static and dynamic properties of EuO and EuS

International Nuclear Information System (INIS)

Lindgard, P.A.

1981-10-01

The paramagnetic scattering was recently measured for EuO. It was found that spin-wave-like excitations develop for wave vectors approaching the zone boundary. The spectrum was found to be well described by damped harmonic oscillators (also called the two-pole-approximation). This approximation was used previously in the correlation theory primarily to calculate static properties. Selfconsistent dynamic and static calculations have been performed for EuO, which is an ideal Heisenberg magnet with significant second nearest neighbor interaction (J 2 = J/sub 1/5). The two-pole approximation describes accurately the correlation range, the static susceptibility and the qualitative behavior of the dynamic properties (i.e., the wave vector at which peaks appear in the spectrum as a function of temperature). However, in order to also obtain the correct frequency scale it is necessary to use a cut-off of the spectrum at high frequencies, which cannot be seen experimentally, but which significantly influences the frequency moments. It was found that the finite J 2 has significant importance for a comparison between theory and experiment. It is concluded that the calculation for a simple cubic n.n. magnet by Hubbard does not describe the EuO data accurately, neither with respect to lineshape nor frequency scale. Significant differences are to be expected between EuO and EuS having opposite sign for J 2

Over the last decades, researchers have explored nanotechnological applications in different areas. The non-hydrolytic and hydrolytic sol–gel routes offer the ideal conditions to obtain materials with distinct compositions and multifunctionality, for use in such diverse areas as nanomedicine and technology. In this work, we used the modified hydrolytic sol–gel route to prepare YVO{sub 4} doped with Eu{sup 3+} ion. The YVO{sub 4}:Eu{sup 3+} nanoparticles were functionalized with 3-chloropropyltriethoxysilane using the hydrolytic sol–gel process; the drug cisplatin was then added to them. The final powder was characterized by thermal analysis, infrared spectroscopy, X-ray diffraction, and photoluminescence. The powder X-ray diffraction patterns of the samples obtained before and after functionalization revealed well defined peaks ascribed to the tetragonal structure of the YVO{sub 4} phase. The thermal analysis curves evidenced mass loss relative to 3-chloropropyltriethoxysilane and cisplatin decomposition. Infrared spectroscopy showed the peaks related to the CH and NH groups vibration modes, confirming YVO{sub 4} functionalization. The excitation and emission spectrum of the Eu{sup 3+} ion did not change upon its doping into the matrix functionalized with 3-chloropropyl and cisplatin. Cytotoxicity tests conducted on normal Chinese hamster (V79 cells) and murine melanoma (B16F10) cells attested that the matrix was not toxic. - Highlights: • Sol–gel methodology was used to obtain luminescent YVO{sub 4}. • Matrix was functionalized by alkoxide. • YVO{sub 4} matrix was not toxic. • YVO{sub 4}:Eu{sup 3+} nanoparticles existed in the cell cytoplasm and nucleus. • YVO{sub 4}:Eu{sup 3+} can function as a fluorescent label and drug delivery system.

Rethinking EU Citizenship: Towards the Postmodern Ethics of Citizenship

Directory of Open Access Journals (Sweden)

Sanja IVIC

2009-11-01

Full Text Available The concept of EU citizenship reflects EU politics of (fixed identity, which guarantees rights only to the homogenous groups (and individuals as representatives of these groups. Hence, it leaves room for marginalizing, othering, excluding and other forms of discrimination, by creating binary oppositions: we/they, citizen/alien, EU/non-EU and so forth. EU citizenship is based on the modernist ethics of priority of right over the good. It is created to promote European idea, so it has only instrumental value. On the other hand, the politics of affinity leads to the substantive EU citizenship founded on multiple identities. The politics of affinity requires a new ethics which will lead to transformation of the main concepts of EU legal discourse.

Exporting EU Liberalism Eastwards

Full Text Available There is much more to liberalism in the post communist context than has been acknowledged. A sizeable effort has indeed emerged to transplant a relatively coherent liberal ideology to the region, one exported not merely through the conditionality of international financial institutions, but also through the conditionality and socialization of organizations like the NATO, OSCE, EU, and the Council of Europe. ‘EU liberalism’ includes the ‘standard’ liberal emphasis on individual rights, the rule of law, constitutional democracy, freedom, and market economics as well as support for minority rights, and a seemingly schizophrenic emphasis on economic integration that involves, first bringing down borders for the free movement of people, goods, capital, and services between member states, and second, market regulation to diminish the social downsides of capitalism. This paper outlines EU liberalism’s emergence and its application to Central and East European countries.

The EU's Convergence Dilemma

Directory of Open Access Journals (Sweden)

Notermans Ton

2015-02-01

Full Text Available As economic stagnation continues to mark the EU in the fifth year of the euro zone crisis, political support for integration is waning. The European Parliament elections of 2014 returned a hitherto unparalleled number of Eurosceptic MEPs, with EU-critical parties becoming the largest ones in several Member States. Much of this Euroscepticism is driven by economic polarisation between core and peripheral countries. While an increasing number of voters in the northwestern creditor countries resent having to foot the bill for what they consider economic mismanagement in the periphery, voters in peripheral countries increasingly rebel against what they deem to be an economically catastrophic Diktat from Germany and its allies. Continued political support for European integration will hinge on successful income convergence in the EU but the current dilemma is that such policies might not be politically feasible. Periods of rapid convergence would seem to suggest that success depends on two main policy strategies. First, a monetary policy that promotes credit for productive purposes, leaves inflation control to other instruments, and employs selective credit rationing to prevent asset booms. Second, a vertical industrial policy prioritising selected industrial sectors. The first policy conflicts with the present framework of euro zone monetary policy, but that framework was only installed in the first place because many peripheral countries were desperately in search of an external constraint on domestic distributional conflict. Industrial policies, in turn, require a sufficient degree of state autonomy from business elites in order to be effective, but it is highly questionable whether most states in the EU possess such autonomy. Though there are, as yet hesitant, signs of a reorientation of both monetary and cohesion policy in the EU, the question of the institutional and political preconditions for their successful implementation has been largely

Evidence-based practice guidelines in OHS: are they agree-able?

2007-01-01

The purpose of this study was to evaluate the acceptance, validity, reliability and feasibility of the AGREE (Appraisal of Guidelines and REsearch and Evaluation) instrument to assess the quality of evidence-based practice guidelines for occupational physicians. In total, 6 practice guidelines of the Netherlands Society of Occupational Medicine (NVAB) were appraised by 20 occupational health professionals and experts in guideline development or implementation. Although appraisers often disagreed on individual item scores, the internal consistency and interrater reliability for most domains was sufficient. The AGREE criteria were in general considered relevant and no major suggestions for additional items for use in the context of occupational health were brought up. The domain scores for the individual guidelines show a wide variety: 'applicability' had on average the lowest mean score (53%) while 'scope and purpose' had the highest one (87%). Low scores indicate where improvements are possible and necessary, e.g. by providing more information about the development. Key experts in occupational health report that AGREE is a relevant and easy to use instrument to evaluate quality aspects and the included criteria provide a good framework to develop or update evidence-based practice guidelines in the field of occupational health.

Implementing SDG 15.3 on Land Degradation Neutrality in the EU and EU Member States

Science.gov (United States)

Wunder, Stephanie; Starke, Sue Martina; Frelih-Larsen, Ana; Kaphengst, Timo

2017-04-01

The continuing degradation of land and soils is a severe threat to the provision of ecosystem services and economic development. Sustainable use of land and soils are therefore an integral part of the "Agenda 2030" with its 17 Sustainable Development Goals (SDGs) and 169 targets adopted by the UNGeneral Assembly in September 2015. The SDGs provide new opportunities for an ambitious and integrated environmental policy worldwide and in the EU. Among the many relevant targets that directly or indirectly address soils (such as goals on zero hunger, well being, clean energy, climate change, water and sustainable cities), target 15.3 that aims to achieve "a land degradation-neutral world" by 2030 is the most relevant. The concept of "Land Degradation Neutrality" (LDN) is not only about halting the loss of healthy and fertile land, but also actively reversing degradation by restoring land in order to counterbal-ance losses that cannot be avoided. It is a very ambitious target but due to a lack of balancing mechanisms for degradation and restoration in most countries also a new concept. Land Degra-dation Neutrality therefore both needs a scientific conceptual framework as well as a political debate about its implementation and development of instruments. In the EU and its Member States, this debate can also serve as a catalyst to revive the discussion on a common soil policy in Europe after the withdrawal of the proposal for a soil framework directive in 2014. To analyze options for the implementation of target 15.3 in Germany and Europe the research project "Implementing the Sustainable Development Goals on Soils in Germany" (http://ecologic.eu/12876) is currently carried out by the Ecologic Institute on behalf of the Ger-man Environment Agency (UBA) and the German Federal Environment Ministry (BMUB). The project will run until spring 2017 and the session "European Environmental Policies and Sustainability" at the EGU will be an ideal opportunity to present the final

Coordinating the Uncoordinated: The EU Forest Strategy

Directory of Open Access Journals (Sweden)

Filip Aggestam

2018-03-01

Full Text Available The second European Union (EU Forest Strategy responds to new challenges facing both forests and the forest-based sector which highlights the EU’s need for a policy framework ensuring coordination and coherence of forest-related policies. The objective of the present article is to analyse whether the new Strategy contributes towards horizontal policy coherence of EU forest-related policies, given its shared and exclusive competences. This is achieved by comparing European Commission and forest industry policy priorities as articulated in the Strategy and through research carried out for the recent Cumulative Cost Assessment (CCA of forest-based industries. Results from the comparative analysis demonstrate that the Strategy does not address many EU policies and policy instruments that affect the whole forest value chain and that it clearly omits existing EU policy instrument objectives that entail significant costs for the forest-based industry. It is therefore argued that without coordinating collective EU goals and gathering strong political support, it is at best extremely difficult or at worst impossible, to achieve coherence for EU forest-related policies across the whole forest value chain. Improving coherence of Union forest-related policies will require the Strategy to address more policy areas and instruments, including clearly defined parameters of what constitutes an EU forest-related policy. These pressing needs reach beyond what the Strategy presently sets out to achieve.

IMPACTS OF CLIMATE CHANGE ON EU AGRICULTURE

Shailesh Shrestha

2013-09-01

Full Text Available The current paper investigates the medium term economic impact of climate changes on the EU agriculture. The yield change data under climate change scenarios are taken from the BIOMA (Biophysical Models Application simulation environment. We employ CAPRI modelling framework to identify the EU aggregate economic effects as well as regional impacts. We take into account supply and market price adjustments of the EU agricultural sector as well as technical adaptation of crops to climate change. Overall results indicate an increase in yields and production level in the EU agricultural sector due to the climate change. In general, there are relatively small effects at the EU aggregate. For example, the value of land use and welfare change by approximately between -2% and 0.2%. However, there is a stronger impact at regional level with some stronger effects prevailing particularly in the Central and Northern EU and smaller impacts are observed in Southern Europe. Regional impacts of climate change vary by a factor higher up to 10 relative to the aggregate EU impacts. The price adjustments reduce the response of agricultural sector to climate change in particular with respect to production and income changes. The technical adaption of crops to climate change may result in a change production and land use by a factor between 1.4 and 6 relative to no-adaptation situation.

Legal Status of the Catholic Church as an Economic Entity in EU and Croatian Law

Full Text Available Regulation of the Catholic Church’s legal status in the European Union primarily falls within the competences of the Member States. The Croatian legal framework in this respect consists of various types of legal rules, most important of which is the set of international agreements entered into between the Republic of Croatia and the Holy See. Still, EU competition, state aid and free movement rules affect this legal framework to a significant degree. The aim of this paper is to analyse the applicability of the said EU rules to the activities of the Catholic Church in Croatia, that is to determine whether the Catholic Church can be considered an undertaking conducting an economic activity (and to what degree according to the said legal framework, whether the Croatian national legal framework is aligned with the EU rules, and whether there are points of contention in this area which need to be legally rectified. The second part of this paper analyses the European Union state aid and free movement legal framework, primarily trying to determine whether the Catholic Church is an undertaking carrying out an economic activity as prescribed by EU law. In this analysis, several issues emerge which have not been clearly resolved by the Court of Justice. The following part features an outline of the Croatian national legal framework on the legal status of the Catholic Church, focusing on potential points of contention between the national and the EU law. Finally, certain solutions to the mentioned issues are proposed, on the European and the national level, in accordance with legal certainty as the general principle of (EU law.

The Limits of Conditionality: Turkey – EU Taxation Negotiations

Directory of Open Access Journals (Sweden)

Hakan Cavlak

2015-10-01

Full Text Available Conditionality is mostly defined as the EU policy engendered for candidate countries. However, the mere use of conditionality by the EU does not essentially explain transferring of policies and EU rules towards the candidate countries. EU conditionality may be considered as a comprising approach but in certain policy areas or countries it might not be as successful as it was on other ones. The EU conditionality basically defined as a bargaining policy of affecting through reward, under which the EU provides inducements to candidate or neighbor countries to aligning with the conditions of the EU. In this study the explanatory power of conditionality would be questioned; so the main question will be “to what extent does the EU have influence on policy convergence in a candidate country that does not have a clear membership perspective? Taxation chapter in accession negotiations between Turkey and the EU has been chosen as the case of this research as providing to have an answer on this question. The main objective of this paper is ‘analyzing the extent of EU conditionality on Turkish taxation policy.’ Furthermore, it is argued in this study that “without a concrete incentive, European Union’s impact on a candidate country would be limited.”

2011-03-14

A comprehensive survey of electronic structure and optical properties of rare-earth ions-doped semiconductor is of vital importance for their potential applications. In this work, Eu(3+)-doped β-Ga(2)O(3) nanocrystals were synthesized via a combustion method. The evolution of the optical properties of nanophosphors with increasing the annealing temperature was investigated in detail by means of excitation and emission spectra at room temperature and 10 K. Eu(3+) ions were proved to be incorporated into the crystal lattice of the β-Ga(2)O(3) phase after annealing the as-prepared nanoparticles at 1100 °C. It was observed that the substitution of Eu(3+) for Ga(3+) occurred at merely single site, in spite of two crystallographically nonequivalent sites of Ga(3+) in β-Ga(2)O(3). Spectroscopic evidence corroborated and clarified the local symmetry of C(s) for Eu(3+) at this single site. From the high-resolution excitation and emission spectra, 71 crystal-field levels of Eu(3+) in β-Ga(2)O(3) were identified and analyzed in terms of 19 freely varied free-ions and crystal-field parameters based on C(s) symmetry. The standard deviation of the final fitting is as low as 12.9 cm(-1), indicating an excellent agreement between experimental and calculated energy levels. The temperature-dependent luminescence dynamics of the (5)D(0) multiplet for Eu(3+) in β-Ga(2)O(3) phosphors has also been revealed for the first time from 10 to 300 K.

Graphical abstract: Pure-phase CaZnOS:Eu{sup 2+},Ce{sup 3+}phosphor with good chemical and thermal stability can be synthesized by co-doping with Ce{sup 3+} as deoxidizer rather than reduction atmosphere. The broad bluish-green excitation and broad red emission show it is a better phosphor than CaS:Eu{sup 2+} for white LED and for sunlight harvesting of plants. -- Highlights: • Pure-phase phosphor CaZnOS:Eu{sup 2+} was synthesized by co-doping with Ce{sup 3+} as deoxidizer. • Energy transfer mechanism from Ce{sup 3+} to Eu{sup 2+} in CaZnOS host is proposed. • CaZnOS:Eu{sup 2+}, Ce{sup 3+} phosphor has good chemical and thermal stability performance. • The similarities and differences between CaZnOS:Eu{sup 2+} and CaS:Eu{sup 2+} were analyzed. • The green excitation and red emission show superior solar harvesting for plants. -- Abstract: The red-emitting phosphor CaZnOS:Eu{sup 2+} was synthesized from CaCO{sub 3}, ZnS, Eu{sub 2}O{sub 3} and CeCl{sub 3} by controlling the sintering condition. It was found that Ce{sup 3+} ions can play a role of reductant to contribute to the formation of Eu{sup 2+} in CaZnOS matrix under inert protective atmosphere. While the gas flow changed to H{sub 2}/N{sub 2}, the product turned to CaS easily. XRD, photoluminescence spectra, UV–vis and IR absorption spectra were evaluated to investigate the origin of the distinctions of the optical properties and stabilities between the two divalent europium ions doped phosphors CaZnOS:Eu{sup 2+} and CaS:Eu{sup 2+}. The similarities and differences between them were analyzed.

Tipping the scale? Social media’s influences on EU attitudes and vote choice in the Danish 2015 EU referendum

2017-01-01

The EU’s role to assist Turkey in its democratization efforts has been debated during Turkey’s candidacy. However, in the second decade of the 21st century, this role of the EU lost its visibility while Turkey seemed to lose its interest in reform movements. This paper, inspired by Pevehouse, defines the EU as a supplier of democratization mechanisms and Turkey as an actor in need. Although lack of enthusiasm and disengagement have come to characterize Turkey-EU relations, this study aims to ...

1999-10-01

This final report presents the results of the analyses at relevant trends and features in the EU gas market enabling or limiting more competition. The study focuses in particular on the possible impacts of the implementation of the EU Gas Directive and subsequently of the expected effects of increasing competition and further integration of gas markets in Europe. The study is conducted in the framework of the Shared Analysis project entitled 'Economic Foundations for Energy Policy', coordinated by FhG-ISI and prepared for the European Commission Directorate General for Energy. The report contains an analysis of the recent changes in the structure of gas demand and the supply and its consequences for enhancement of competition in the EU gas market. lt discusses the role of growing gas demand, changing structure of the supply industry and access to the network. Next, the implementation of the EU Gas Directive is discussed. In order to deal with the uncertainty in the results of the implementation process, two extreme institutional scenarios for future development of the liberalisation process in the EU gas markets are formulated. Finally, the consequences of these two gas market liberalisation scenarios are analysed. Note that part of the conclusions of the expected effects of the Directive, i.e. the expected changes in gas prices and market structures, are based on a model analysis. However, it should be clear that at this stage our conclusions presented in this report are still of a tentative nature. Note also that the final report is based on an extensive collection of EU gas market data both on country and company level, which was described in the first interim report entitled 'The natural gas market in the European Union'. A second interim report was drafted with an energy policy interpretation of the analyses of data and developments over the past ten years. Furthermore, at this moment, facts, opinions and available data are rapidly changing in the beginning of

Cost evaluation of energy crops at farm gate in different EU countries and related agricultural issues

1996-01-01

Interest on energy crops varies greatly among EU regions. Certain climatic conditions prevailing in the areas, determine the coice of the energy crop which is going to be used as raw material for energy production. Furthermore, energy markets, farm structure and set aside regulations as well as national policy play a critical role to biomass exploitation for energy purposes. A common methodology was developed (Moore, 1996) for comparing costs of different options for ''biomass-to-energy systems'' across six EU countries (figure 1). This methodology was developed in the framework of an AIR Concerted Action financed by DGXII of EU and entitled ''Development of a Standard Methodology for Integrating Non-Food Crops in Rural Areas with Niche Energy Markets''. Cost estimations were done form the first stage of raw material production till the final energy product (kWh of heat and electricity or lt of liquid biofuel. In this paper, only the raw material production cost estimation phase will be presented. (Author)

Nanocrystals of rare-earth garnets Y3Al5O12 and Lu3Al5O12 and perovskite GdAlO3 highly doped (10-20 at%) with Eu3+ are synthesized by the solution combustion technique and subsequent annealing in air at 800 and 1300oC. Their structure, morphology, and phase composition are studied. These materials exhibit intense red luminescence under UV excitation. Eu:GdAlO3 luminescence has CIE 1931 color coordinates (0.632, 0.368); dominant wavelength, 599.6 nm; and color purity, >99%. Judd-Ofelt parameters, luminescence branching ratios, and lifetimes of the Eu3+ 5D0 state are determined. The luminescence quantum yield for Eu:GdAlO3 (10 at%) reaches 74% with a lifetime of 1.4 ms for the 5D0 state. The synthesized materials are promising for red ceramic phosphors.

EU Emission Trading - better job second time around?

Schleich, Joachim |; Betz, Regina; Rogge, Karoline |

2007-01-01

The EU Emission Trading Scheme (EU ETS) for CO 2 -emissions from energy and industry installations reflects a paradigm shift towards market-based instruments for environmental policy in the EU. The centerpieces of the EU ETS are National Allocation Plans (NAPs), which individual Member States (MS) design for each phase. NAPs state the total quantity of allowances available in each period (ET-budget) and determine how MS allocate allowances to individual installations. The NAPs thus govern investments and innovation in energy efficient technologies and the energy sector. In terms of distribution, they predetermine winners and losers. In this paper we analyze and evaluate 25 NAPs submitted to the European Commission (EC) for phase 2 (2008-2012) of the EU ETS. At the macro level, we assess whether the submitted ET-budgets are stringent, and whether they imply a cost-efficient split of the required emission reductions between the EU ETS sectors (energy and industry) and the remaining sectors (transportation, tertiary and households). Comparing the submitted ET-budgets with those already approved by the EC suggests that the EC's decisions significantly improved the effectiveness and economic efficiency of the EU ETS. But given the high share of Kyoto Mechanisms companies are allowed to use, the EU ETS is unlikely to require substantial emission reductions within the EU. At the micro level, we assess (across countries and phases) the allocation methods for existing and new installations, for closures and for clean technologies. A comparison of the NAPs for the second phase and the first phase (2005-2007) provides insights into the (limited) adaptability and flexibility of the scheme. The findings provide guidance for the future design of the EU ETS and applications to other sectors and regions

Highlights: • We show that EuPdGe{sub 3} crystallizes in the BaNiSn{sub 3}-type structure with the lattice constants a = 4.4457(1) Å and c = 10.1703(2). • We demonstrate that EuPdGe{sub 3} is an antiferromagnet with the Néel temperature T{sub N} = 12.16(1) K. • The temperature dependence of the hyperfine magnetic field follows a S = 7/2 Brillouin function. • We find that the Debye temperature of the studied compound is 199(2) K. - Abstract: The results of X-ray diffraction, magnetic susceptibility and magnetization, and {sup 151}Eu Mössbauer spectroscopy measurements of polycrystalline EuPdGe{sub 3} are reported. EuPdGe{sub 3} crystallizes in the BaNiSn{sub 3}-type tetragonal structure (space group I4mm) with the lattice constants a=4.4457(1)Å and c=10.1703(2)Å. The results are consistent with EuPdGe{sub 3} being an antiferromagnet with the Néel temperature T{sub N}=12.16(1)K and with the Eu spins S=7/2 in the ab plane. The temperature dependence of the magnetic susceptibility above T{sub N} follows the modified Curie-Weiss law with the effective magnetic moment of 7.82(1) μ{sub B} per Eu atom and the paramagnetic Curie temperature of -5.3(1)K indicative of dominant antiferromagnetic interactions. The M(H) isotherms for temperatures approaching T{sub N} from above are indicative of dynamical short-range antiferromagnetic ordering in the sample. The temperature dependence of the hyperfine magnetic field follows a S=7/2 Brillouin function. The principal component of the electric field gradient tensor is shown to increase with decreasing temperature and is well described by a T{sup 3/2} power-law relation. The Debye temperature of EuPdGe{sub 3} determined from the Mössbauer data is 199(2) K.

Consumers are increasingly turning their attention to the quality and origin of products that they consume. European Union (EU) quality schemes are associated with a label, which was introduced to allow consumers to perform an informed choice and to protect producers from unfair practices. This present study provides an overview of the last 25 years of EU quality schemes [Protected Designations of Origin (PDO), Protected Geographical Indications (PGI) and Traditional Specialities Guaranteed (TSG)] on agricultural products and foodstuffs across the 28 EU Member States. According to the results, it was possible to conclude that Southern European countries have the highest number of registered products. The most used EU quality scheme is PGI, followed by PDO. Concerning the analysis of the evolution in the last 25 years, the number of registered products among EU Member States has increased significantly. The fruit, vegetables and cereals (fresh or processed) category is the one that accounts for the highest percentage (26.8%) of registered products, followed by cheeses and meat products (cooked, salted, smoked) categories, with 17.2% and 13.5%, respectively. Further investigations should address consumer preferences, knowledge and attitudes, especially Northern European countries with a lower number of registered products. Moreover, the investigation and registration of products should be encouraged among all EU Member States to allow the maintenance of important elements of the history, culture and heritage of the local areas, regions and countries. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

Six SD bands were populated in {sup 143}Eu and {sup 144}Eu, two of which had not been previously observed. Sum spectra were generated to search for two step links from the yrast SD band in {sup 143}Eu. However, no two step links were found. A single link from the SD band in {sup 143}Eu was found at 3364 keV. The level where it feeds into has not been identified. Alpha-particle energy (E{sub {alpha}}) spectra leading to the SD band and to normal states in {sup 143}Eu were measured and a correlation was found between E{sub {alpha}} and the level spin of the residual nucleus.

2016-04-01

The European Marine Observation and Data Network (EMODnet) initiative has the following purposes: to assemble marine metadata, data and products, to make these fragmented resources more easily available to public and private users and to provide quality-assured, standardised and harmonised marine data. EMODnet Chemistry was launched by DG MARE in 2009 to support the Marine Strategy Framework Directive (MSFD) requirements for the assessment of eutrophication and contaminants, following INSPIRE Directive rules. The aim is twofold: the first task is to make available and reusable the big amount of fragmented and inaccessible data, hosted in the European research institutes and environmental agencies. The second objective is to develop visualization services useful for the tasks of the MSFD. The technical set-up is based on the principle of adopting and adapting the SeaDataNet infrastructure for ocean and marine data which are managed by National Oceanographic Data Centers and relies on a distributed network of data centers. Data centers contribute to data harvesting and enrichment with the relevant metadata. Data are processed into interoperable formats (using agreed standards ISO XML, ODV) with the use of common vocabularies and standardized quality control procedures .Data quality control is a key issue when merging heterogeneous data coming from different sources and a data validation loop has been agreed within EMODnet Chemistry community and is routinely performed. After data quality control done by the regional coordinators of the EU marine basins (Atlantic, Baltic, North, Mediterranean and Black Sea), validated regional datasets are used to develop data products useful for the requirements of the MSFD. EMODnet Chemistry provides interpolated seasonal maps of nutrients and services for the visualization of time series and profiles of several chemical parameters. All visualization services are developed following OGC standards as WMS and WPS. In order to test new

(Sr, Ca, Ba)Al₂O₄:Eu 2+ , Dy 3+ phosphors were prepared via a high temperature solid-state reaction method. The correlation of phase structure, optical properties and lifetimes of the phosphors are investigated in this work. For the (Sr, Ca)Al₂O₄:Eu 2+ ,Dy 3+ phosphors, the different phase formation from monoclinic SrAl₂O₄ phase to hexagonal SrAl₂O₄ phase to monoclinic CaAl₂O₄ phase was observed when the Ca content increased. The emission color of SrAl₂O₄:Eu 2+ , Dy 3+ phosphors varied from green to blue. For the (Sr, Ba)Al₂O₄:Eu 2+ , Dy 3+ phosphors, different phase formation from the monoclinic SrAl₂O₄ phase to the hexagonal BaAl₂O₄ phase was observed, along with a shift of emission wavelength from 520 nm to 500 nm. More interestingly, the decay time of SrAl₂O₄:Eu 2+ , Dy 3+ changed due to the different phase formations. Lifetime can be dramatically shortened by the substitution of Sr 2+ with Ba 2+ cations, resulting in improving the performance of the alternating current light emitting diode (AC-LED). Finally, intense LEDs are successfully obtained by combining these phosphors with Ga(In)N near UV chips.

In this paper, radiological impacts on human beings during normal execution of the decommissioning operations from the current standard design of EU-APR which has been modified and improved from its original design of APR1400 to comply with EUR, are evaluated. Decommissioning is the final phase in the life cycle of a nuclear installation, covering all activities from shutdown and removal of fissile material to environmental restoration of the site. According to article 5.4 specified in chapter 2.20 of European Utility Requirements (EUR), all relevant radiological impacts on human being should be considered during the environmental assessment of decommissioning, including external exposure from direct radiation of plant and other radiation sources, and internal exposure due to inhalation and ingestion. In this paper, radiological impacts on human beings during normal circumstances of the decommissioning operation were evaluated from the current standard design of EU-APR based on the simple transport model and practical generic methodology for assessing the radiological impact provided by IAEA. The results of dose assessment fulfilled the dose limit for all scenarios.

2015-07-20

We found an enhancement of Eu{sup 3+} emissions in Eu-doped ZnO nanocrystalline films fabricated by microemulsion method. The Eu{sup 3+} emission intensities were increased by reducing annealing temperatures from 633 K to 533 K. One possible explanation for this phenomenon is that the size reduction enhances the energy transfer from ZnO nanoparticles to Eu{sup 3+} ions. Also, the shift of the charge-transfer band into the low-energy side of the absorption edge is found to be crucial, which seems to expedite the energy transfer from O atoms to Eu{sup 3+} ions. These findings will be useful for the material design of Eu-doped ZnO phosphors.

Full Text Available Phosphor-converted white light emitting diodes (white LEDs have received great attention in recent years since they have several excellent features such as high lumen output, low power consumption, long lifetime and environmentally friendly. In this work, we report the co-precipitation synthesis of red/blue Sr2MgSi2O7:Eu3+/Eu2+ phosphors with various Eu doping concentration. The results show that the obtained Sr2MgSi2O7:Eu3+/Eu2+ phosphors have good crystallinity and emit strong red (Sr2MgSi2O7:Eu3+ and blue (Sr2MgSi2O7:Eu2+ emissions under near UV light excitation. The sharp emission peaks at 577, 590, 612, 653, and 701 nm corresponded to the typical 5D0 → 7Fj (j = 0,1,2,3,4 transitions of Eu3+, and the blue emission peaking at 460 nm is attributed to the typical 4f65d1-4f7 transition of Eu2+ in the same Sr2MgSi2O7 host lattice. Both phosphors can be well excited in the wavelength range of 260–400 nm where the near UV-LED is well matched. The above results suggest that the Sr2MgSi2O7:Eu3+/Eu2+ phosphors are promising red/blue-emitting phosphors for the application in near UV pumped phosphor-converted white LEDs.

Economic Impacts of the 1997 EU Energy Tax: Simulations with Three EU-Wide Models

International Nuclear Information System (INIS)

Jansen, H.; Klaassen, G.

2000-01-01

In March 1997 the European Commission adopted a proposal that increases existing minimum levels of taxation on mineral oils by around 10 to 25% and introduces excises for other energy products. This paper analyses the macroeconomic impacts of the proposal. It employs three models: HERMES, GEM-E3, and E3ME. All models confirm that the proposal will have positive macroeconomic impacts when the tax revenues are used to reduce social security contributions paid by employers. For the EU as a whole, both GDP and employment are expected to be higher and CO2 emissions are 0.9 to 1.6 percent lower. The positive EU-wide effects can be observed in practically all member states. The sector impacts are modest, with the energy sector expected to face the most negative impacts. Differences between model results are due to the model type (general equilibrium or macro-econometric), the EU countries covered and the way tax exemptions were handled. Crucial assumptions to obtain the 'double dividend' are the modelling of the labour market and the impacts on EU external trade. The sensitivity of the results for the use of tax revenues, tax exemptions and tax rate increases is assessed. 21 refs

EU ENLARGEMENT AT A CROSSROADS

Directory of Open Access Journals (Sweden)

Andreea Cătălina Paul

2012-06-01

Full Text Available The present article aims to explore the general theme of the EU enlargement strategy in the new 2012 European context. Until now, the EU’s enlargement strategy has yielded impressive results. It succeeded in transforming ten central and eastern European countries from post-communism confusion into open-market, mature and effective systems of democratic governments, and even on the economic front, they have also made astonishing progress. It is no doubt that people in the new EU countries live better then before. In this context, the EU must continue the enlargement process to help stabilize the Balkan region that lie beyond its expanded eastern border. No one can deny that major issues concerning western Balkan countries’ accession are still on the table, and they even exert a geopolitical influence of sorts. This makes it all the more important to see stability and regional co-operation there are strategically vital. An all-out effort must now be made to complete the enlargement process and ensure there is no strategic vacuum. This article provides the framework of analyses for the EU problems and the challenges for the Balkans governments as for Brussels.

The interplay of magnetism with superconductivity is a fascinating, highly debated field of research and many questions still remain unsolved. Members of the EuFe{sub 2}As{sub 2} family are a perfectly suited playground for investigations concerning this topic, due to the peculiarity of strong local magnetism of the europium (T{sub N}∼ 20K), which is a unique feature among the 122 iron pnictides. Optical studies of the parent compound have already revealed that the spin density wave formation deviates from the other 122 pnictides. To get more insight into the superconducting properties of the EuFe{sub 2}As{sub 2} family we carried out an optical study on differently doped samples. We compare Eu(Fe{sub 1-x}Ir{sub x}){sub 2}As{sub 2} where electron doping takes place directly in the conducting iron layer, with EuFe{sub 2}(As{sub 1-x}P{sub x}){sub 2} which corresponds to isovalent substitution at atomic positions out of the Fe-plane. The influence of the Eu is furthermore investigated by placing data we obtained on Ba{sub 0.6}Eu{sub 0.4}(Fe{sub 1-x}Co{sub x}){sub 2}As{sub 2} in juxtaposition to the already highly investigated pure Ba analogue.

Pesticide authorization in the EU-environment unprotected?

Science.gov (United States)

Stehle, Sebastian; Schulz, Ralf

2015-12-01

Pesticides constitute an integral part of high-intensity European agriculture. Prior to their authorization, a highly elaborated environmental risk assessment is mandatory according to EU pesticide legislation, i.e., Regulation (EC) No. 1107/2009. However, no field data-based evaluation of the risk assessment outcome, i.e., the regulatory acceptable concentrations (RACs), and therefore of the overall protectiveness of EU pesticide regulations exists. We conducted here a comprehensive meta-analysis using peer-reviewed literature on agricultural insecticide concentrations in EU surface waters and evaluated associated risks using the RACs derived from official European pesticide registration documents. As a result, 44.7 % of the 1566 cases of measured insecticide concentrations (MICs) in EU surface waters exceeded their respective RACs. It follows that current EU pesticide regulations do not protect the aquatic environment and that insecticides threaten aquatic biodiversity. RAC exceedances were significantly higher for insecticides authorized using conservative tier-I RACs and for more recently developed insecticide classes, i.e., pyrethroids. In addition, we identified higher risks, e.g., for smaller surface waters that are specifically considered in the regulatory risk assessment schemes. We illustrate the shortcomings of the EU regulatory risk assessment using two case studies that contextualize the respective risk assessment outcomes to field exposure. Overall, our meta-analysis challenges the field relevance and protectiveness of the regulatory environmental risk assessment conducted for pesticide authorization in the EU and indicates that critical revisions of related pesticide regulations and effective mitigation measures are urgently needed to substantially reduce the environmental risks arising from agricultural insecticide use.

Magnetic oxide heterostructures. EuO on cubic oxides and on silicon

International Nuclear Information System (INIS)

Caspers, Christian

2013-01-01

In the thesis at hand, we explore fundamental properties of ultrathin europium oxide (EuO) films. EuO is a model system of a localized 4f Heisenberg ferromagnet, in which the ferromagnetic coupling. provided a high crystalline quality. can be tuned by biaxial lattice strain. Moreover, the magnetic oxide EuO is perfectly suited as a spin-functional tunnel contact for silicon spintronics. However, up to now a challenging bulk and interface chemistry of EuO and Si has hampered a seamless integration into functional silicon heterostructures. In order to investigate fundamental aspects of the magnetic and electronic structure of ultrathin EuO, in the first part of this thesis, we synthesize EuO thin films on conductive YSZ substrates from bulklike thicknesses down to one nanometer by oxide molecular beam epitaxy (MBE). The EuO thin films are of textbook-like single-crystalline quality, and show bulk-like magnetic properties. We control the stoichiometry of buried EuO thin films by hard X-ray photoemission spectroscopy (HAXPES); even a 1 nm ultrathin EuO film exhibits no valence change or interface shifts. Furthermore, we conduct an advanced magnetic characterization by the magnetic circular dichroism (MCD) of Eu core-levels in photoemission, this gives us insight into the intra-atomic exchange coupling of EuO thin films. The MCD reveals large asymmetries of up to 49% in the well-resolved Eu 4d photoemission multiplet. Thus, ultrathin EuO coherently grown on conductive YSZ allows us to explore fundamental magnetic and electronic properties of a 4f magnetic oxide. Biaxial lateral strain applied to single-crystalline EuO is of fundamental interest, since it alters the electronic structure and magnetic coupling in a controlled way. We apply +4.2% tensile biaxial strain to EuO by epitaxial EuO/LaAlO 3 (100) heterostructures. EuO seamlessly adapts the lateral lattice parameter of LaAlO 3 , while the perpendicular parameter of EuO is the unchanged EuO bulk value, thus the

Furfari, Samuele

2014-01-01

The Ukrainian crisis serves as a reminder just how much Ukraine plays a determining role for the European Union in energy matters, being the funnel through which most of Russian gas has to pass to reach Western Europe. One inevitable conclusion is already obvious: Russia and the EU are intimately linked and Moscow is as dependent on the EU for foreign exchange as is the EU on Russia for its gas. Nevertheless, the absence of stability in Ukraine constitutes a permanent threat to supplies to member states of the EU, especially Germany. (author)

Electrochemical behaviour of the Eu3+/Eu2+ system in propionic media studied by cyclic chrono potentiometry

International Nuclear Information System (INIS)

Brotto, M.E.

1989-01-01

The electrochemical behaviour of the Eu 3 + / Eu 2 + system in propionic media was studied by means of current reversal chrono potentiometry and cyclic chrono potentiometry. Sodium perchlorate was employed as supporting electrolyte. The experiments were carried out at (25.0 ± 0.1) 0 C. The studied variables were the concentration of the electro active species, the composition of the solution and the current density. The cyclic chrono potentiometry results reveal that the charge transfer reaction is followed by the (H 3 O) + ion assisted irreversible catalytic reaction in which the Eu 3 + species is regenerated.

The Impact of EU Financial Crisis and the EU Member States Measures taken to Leave Recession

Directory of Open Access Journals (Sweden)

Simona Moagăr-Poladian

2009-10-01

Full Text Available This paper is focussed on the financial packages and fiscal stimuli measures taken by EU as a group and by each EU country for supporting hard-hit sectors like automotive industry, tourism and construction. The economic crisis from 2008-2009 has led to a sharp decrease of investment climate and a massive contraction of economic activity. This means a sharp decrease of capacity utilisation that had led in time to an excessive unemployment especially in the most hit sectors. The financial rescue measures of EU are comprised in European Economic Recovery Plan (EERP. Measures approved are different from country to country, depending by the political support and the strategy chosen by the government. The EU's response to support the real economy during the economic crisis has been taken very fast and well-organized in certain countries and industries. By contrary, some Member States' recovery measures has been approved late and the rescue strategy wasn’t enough achieved. This has led to a deepening of financial instability and unemployment.

Photoluminescence properties of color-tunable SrMgAl10O17:Eu2+,Mn2+ phosphors for UV LEDs

Ju Guifang; Hu Yihua; Chen Li; Wang Xiaojuan

2012-01-01

Aluminate phosphors SrMgAl 10 O 17 codoped with Eu 2+ and Mn 2+ ions were prepared by solid-state reaction. The phase structure and photoluminescence properties of the as-prepared phosphors were characterized by powder X-ray diffraction, photoluminescence excitation and emission spectra. Upon excitation of UV light, two broad emission bands centered at 470 and 515 nm were observed, and they were assigned to Eu 2+ and Mn 2+ emissions, respectively. The emission color of the phosphors can be tuned from blue to cyan and finally to green by adjusting the concentration ratios of Eu 2+ and Mn 2+ . Effective energy transfer occurs from Eu 2+ to Mn 2+ in the host due to the spectral overlap between the emission band of Eu 2+ and the excitation bands of Mn 2+ . The energy transfer mechanism was demonstrated to be electric dipole–quadrupole interaction. The energy transfer efficiency and critical distance were also calculated. The phosphors exhibit strong absorption in near UV spectral region and therefore they are potentially useful as UV-convertible phosphors for white LEDs. - Highlights: ► The strong absorption of phosphors matches well with the emission band of UV LED. ► The energy transfer from Eu 2+ to Mn 2+ in SrMgAl 10 O 17 was investigated in detail. ► The emission color can be tuned by adjusting the content of Eu 2+ and Mn 2+ . ► Two methods were employed to calculate the critical distance of energy transfer.

Epistemic Dependence and the EU Seal Ban Debate

Directory of Open Access Journals (Sweden)

Lars Christian Blichner

2015-03-01

Full Text Available On September 2009 the European Union (EU adopted a regulation banning the import of seal products into the EU or placing seal products on the EU market. The European Parliament was the main driving force behind the regulation and the EU has been criticised by affected countries outside the EU for not basing this decision on the available expert knowledge. The questions asked are how, given epistemic dependence, non-experts may challenge an expert based policy proposal. Can non-experts hold experts accountable, and if so in what way? Three main tests and ten subtests of expert knowledge are proposed and these tests are then used to assess whether the European Parliament did in fact argue in a way consistent with available expert knowledge in amending the Commission proposal for a regulation.

Full Text Available This paper analyzes possible incidence of pending Croatian EU accession that is to take place on the 1st of July 2013, on the labour migration from Croatia to the European Union. We apply panel data estimators using the data on emigration from 18 EU countries into Germany (which is the EU country with the largest share of ex-Yugoslav and Croatian migrants in order to construct possible scenarios of Croatian migration to the EU.Three scenarios of migration - pessimistic, realistic and optimistic - are drawn and the sensitivity of estimated coefficients on migration from Croatia into Germany during next 25 years is further discussed in detail. We conclude that, similarly to hypothetical Turkish accession, Croatian EU accession is not going to cause massive migration inflows.

Assessing potential impacts of the EVFTA on Vietnam's pharmaceutical imports from the EU: an application of SMART analysis.

Science.gov (United States)

Vu, Huong Thanh

2016-01-01

This paper by adopting the Software on Market Analysis and Restrictions on Trade assessed the ex-ante impact of tariff elimination under the European-Vietnam free trade agreement (EVFTA) on Vietnam's pharmaceutical imports from the EU based on two scenarios. The results showed that although Vietnam's tariff removal for the EU's medicines would not result in a significant increase in Vietnam's imports from the EU, Vietnam's deeper integration with ASEAN + 3 and TPP (the Trans-Pacific Partnership) nations would affect quite slightly on its imports from the EU. Therefore, the EU would be still the most important and biggest source of pharmaceuticals for Vietnam in the near future. In addition, there might be an uneven distribution in Vietnam's import increases by the EU nation, pharmaceutical group and product. The simulation results also pointed out that the EVFTA's trade creation effect would be higher than trade diversion effect and therefore the agreement would improve welfare of Vietnam. When Vietnam extends its coverage of tariff elimination to also TPP and ASEAN + 3, Vietnam's welfare would potentially increase more but Vietnam would face with the relatively high increases of pharmaceutical imports from not only the EU but also the US, Australia, South Korea, Thailand and China. Bases on these results, the paper argued that both the Vietnamese government and pharmaceutical enterprises should not neglect the EVFTA and its impacts on the pharmaceutical sector, and perceive clearly the uneven distribution of Vietnam's import changes from the EU by nation and by product to design appropriate business and investment strategy. In addition, Vietnam should take measures to diversify its European import markets to be less dependent on the traditional ones in the current context of the EU. Finally, Vietnam should promote the integration in the pharmaceutical sector with all three groups of nations, especially ASEAN and ASEAN's key partners, to reduce trade diversion

Barriers to the EU Single Services Market

Directory of Open Access Journals (Sweden)

Ol'ga V. Biryukova

2015-01-01

Full Text Available The EU has the most developed liberalization mechanism in services trade within the framework of an economic bloc. The system of supranational institutions, which decisions are binding upon member states, contributes to a high level of liberalization of trade in services in the EU. However, the creation of a single market for services hasn't completed at all. The reasons are following: not all basic principles for single market are fully applied, and a service is a very specific object for international trade. Financial-economic crisis caused a new wave of protectionism in different countries, which has reflected in the preservation of old and the emergence of new barriers to trade in services within the EU. Integration of services in the Union is accompanied by important trade initiatives at the multilateral level. In the World Trade Organization EU countries negotiate a new agreement on trade in services, and offer provisions which providing transparency, deepening liberalization and investor protection for foreign investors in the market, will also complement and foster the Transatlantic Trade and Investment Partnership (TTIP EU - USA. Russia is only the fourth among most important partners of the EU in trade in services. At the same time the European Union remains a key Russian partner in trade in services and in goods. There is a considerable potential for growth in this sphere for both partners.

Business interest of Gazprom in the EU-27 in 2007

International Nuclear Information System (INIS)

Meijknecht, J.

2008-04-01

Gazprom is an important supplier of gas to the EU. Liberalisation of the EU gas market has also influenced the gas relations with Russia and the way the Russian Gas company Gazprom is securing its interest in this internal EU market. From a relationship of bilateral gas contracts with EU member states and their companies before gas market liberalisation, a new approach to secure its market share is beginning to evolve. The positioning of Gazprom in the EU market has raised concerns of EU policy makers. There is some trepidation that the investment strategy of Gazprom in the EU gas market will lead to a position of market dominance in an increasingly import dependent EU market. The discussion on Gazprom's market strategy needs to be fed with factual information on its activities and it is exactly what this new report is providing because information on the activities of Gazprom in the various member states' gas sector was incomplete. In this factual report in Dutch, the author presents a comprehensive oversight and characterisation of Gazprom's downstream assets in the EU-27. Through four layers - long-term contracts, company stakes, asset swaps and political support - a detailed insight is given in Gazprom's downstream activities in the EU-27. [nl

The new Zintl phases Eu{sub 21}Cd{sub 4}Sb{sub 18} and Eu{sub 21}Mn{sub 4}Sb{sub 18}

Crystals of two new Zintl compounds, Eu{sub 21}Mn{sub 4}Sb{sub 18} and Eu{sub 21}Cd{sub 4}Sb{sub 18} have been synthesized using the molten metal flux method, and their structures have been established by single-crystal X-ray diffraction. Both compounds are isotypic and crystallize in the monoclinic space group C2/m (No. 12, Z=4). The structures are based on edge- and corner-shared MnSb{sub 4} or CdSb{sub 4} tetrahedra, which make octameric [Mn{sub 8}Sb{sub 22}] or [Cd{sub 8}Sb{sub 22}] polyanions. Homoatomic Sb–Sb bonds are present in both structures. The Eu atoms take the role of Eu{sup 2+}cations with seven unpaired 4f electrons, as suggested by the temperature-dependent magnetization measurements. The magnetic susceptibilities of Eu{sub 21}Mn{sub 4}Sb{sub 18} and Eu{sub 21}Cd{sub 4}Sb{sub 18} indicate that both phases order anti-ferromagnetically with Néel temperatures of ca. 7 K and ca. 10 K, respectively. The unpaired 3d electrons of the Mn atoms in Eu{sub 21}Mn{sub 4}Sb{sub 18} do contribute to the magnetic response, however, the bulk magnetization measurements do not provide evidence for long-range ordering of the Mn spins down to 5 K. Electrical resistivity measurements suggest that both compounds are narrow band gap semiconductors. - Graphical abstract: Eu{sub 21}Mn{sub 4}Sb{sub 18} and Eu{sub 21}Cd{sub 4}Sb{sub 18} have complex monoclinic structures, based on MnSb{sub 4} and CdSb{sub 4} tetrahedra, both edge- and corner-shared. A perspective of the crystal structure is shown, as viewed along the b axis. Display Omitted - Highlights: • Eu{sub 21}Mn{sub 4}Sb{sub 18} and Eu{sub 21}Cd{sub 4}Sb{sub 18} are novel compounds in the respective ternary phase diagrams. • For both structures, the Zintl-Klemm rules are followed, and both are small gap semiconductors. • Eu{sub 21}Mn{sub 4}Sb{sub 18} and Eu{sub 21}Cd{sub 4}Sb{sub 18} are air-stable Zintl phases and could be new thermoelectric materials.

This report, written in partnership with I4CE and IFPen, provides the first complete and comprehensive assessment of the EU Commission's proposal and its coherence with the 2030 Framework for Climate and Energy policies, demonstrating that: 1 - Re-calibrating the EU ETS requires considering its interactions with complementary climate and energy policies by 2030. Interactions between different policies may induce additional costs vis-a-vis an optimal transition to a low-carbon economy. 2 - Introducing the Market Stability Reserve is necessary to support the ambition of the EU ETS. Guaranteeing MSR effectiveness calls for a governing framework to be established before 2030. 3 - The free allocation mechanism for Phase IV requires more flexible and targeted allocation to sectors most exposed to carbon leakage risk. 4 - Expanding the EU ETS scope with the inclusion of the road transport sector may not necessarily be the most cost-effective way to achieve the GHG 2030 target. 5 - Considering the large scale of ETS auction revenues by 2030, the use of ETS proceeds by the European Commission and by Member States constitutes an increasingly relevant funding source to support decarbonization efforts in non-ETS sectors and to finance R and D in low carbon technologies

In relation with coping with global environmental problems in recent years, needs are increasing more than ever for enhancing fossil energy utilization rates, developing and expanding utilization of petroleum substituting energies that can substitute fossil energies. Since Japan is particularly a large energy consuming country, and cannot escape from depending on import for the majority of its energy resources, it is an urgent issue to enhance the energy utilization efficiency and further promote development and utilization of new energies. To do this, it is indispensable to exchange such item of information as identification of actual status in other countries of handling the petroleum substituting energies. Taking up geothermal energy, fiscal 1998 invited four experts from EU countries. Visits were made for about two weeks on Japanese research institutes and business enterprises related to geothermal energy, and opinions and information were exchanged. A seminar was held on the final day, where the EU experts have made presentations on the current status and future prospects on geothermal research and development in EU. Greatly valuable suggestions were given for the Japan's future geothermal research and development. (NEDO)

Ligand L, based on two do3a moieties linked by the methylene groups of 6,6'-dimethyl-2,2'-bipyridine, was synthesized and characterized. The addition of Ln salts to an aqueous solution of L (0.01 M Tris-HCl, pH 7.4) led to the successive formation of [LnL] and [Ln(2)L] complexes, as evidenced by UV/Vis and fluorescence titration experiments. Homodinuclear [Ln(2)L] complexes (Ln = Eu, Gd, Tb, Yb, and Lu) were prepared and characterized. The (1)H and (13)C NMR spectra of the Lu and Yb complexes in D(2)O solution (pD = 7.0) showed C(1) symmetry of these species in solution, pointing to two different chemical environments for the two lanthanide cations. The analysis of the chemical shifts of the Yb complex indicated that the two coordination sites present square antiprismatic (SAP) coordination environments around the metal ions. The spectroscopic properties of the [Tb(2)L] complex upon ligand excitation revealed conventional behavior with τ(H2O) = 2.05(1) ms and ϕ(H2O) = 51%, except for the calculation of the hydration number obtained from the luminescent lifetimes in H(2)O and D(2)O, which pointed to a non-integer value of 0.6 water molecules per Tb(III) ion. In contrast, the Eu complex revealed surprising features such as: 1) the presence of two and up to five components in the (5)D(0)→(7)F(0) and (5)D(0)→(7)F(1) emission bands, respectively; 2) marked differences between the normalized spectra obtained in H(2)O and D(2)O solutions; and 3) unconventional temporal evolution of the luminescence intensity at certain wavelengths, the intensity profile first displaying a rising step before the occurrence of the expected decay. Additional spectroscopic experiments performed on [Gd(2-x)Eu(x)L] complexes (x = 0.1 and 1.9) confirmed the presence of two distinct Eu sites with hydration numbers of 0 (site I) and 2 (site II), and showed that the unconventional temporal evolution of the emission intensity is the result of an unprecedented intramolecular Eu-to-Eu

Part of the EaP agenda is to advance energy cooperation between the EU and the partner states, particularly regarding the diversification of import routes. As an energy corridor between the EU and the hydrocarbon-rich Caspian states, Turkey is a strategic asset for European energy security. Turkey also has economic ties and political capital in the Caspian region that can help the EU reach out to its eastern partners. Despite robust incentives for cooperation, however, the EU-Turkey energy partnership has so far failed to meet mutual expectations. This article argues that this is primarily due to the inability of the two actors to credibly commit to regional energy cooperation. Commitment problem stems from two factors. First, the predominance of national energy interests over communal ones undermines credible commitment. The variation in energy needs of Member States prevents the EU from acting in unison in external energy policy. Similarly, Turkey also prioritizes its own energy security, particularly in its relations with suppliers, which undermines cooperation with the EU. Second, the EU and Turkey hold divergent perspectives on the potential political payoffs of energy cooperation. Turkish decision makers are convinced that energy cooperation warrants palpable progress in Turkey’s accession while most EU actors appear hesitant to establish a direct connection between energy and accession.

Directory of Open Access Journals (Sweden)

Ferdi de Ville

2013-10-01

Full Text Available This paper aims to convince the reader of the potential of a critical version of historical institutionalism (HI as a theoretical perspective for EU trade policy analysis. It argues that critical HI sensitises the analyst to important but hitherto often neglected factors including: the influence of the past on EU trade policy; the complex, multiarena and multilevel nature of contemporary trade policy; and issues of distributional conflict. The core concept in critical HI is ‘reactive sequencing’, conceiving of policy evolution as a chain of events produced by reactions and counter-reactions. This paper demonstrates that this is invaluable to understand contemporary EU trade politics. Some examples of EU trade policy decisions and its general strategic evolution since the conclusion of the Uruguay Round are given to show the value of critical HI. Finally, the external dimension of “Europe 2020” as the latest trade policy strategy is analysed from a critical historical institutionalist angle.

Advanced Stirling Radioisotope Generator EU2 Anomaly Investigation

Science.gov (United States)

Lewandowski, Edward J.; Dobbs, Michael W.; Oriti, Salvatore M.

2016-01-01

The Advanced Stirling Radioisotope Generator (ASRG) Engineering Unit 2 (EU2) is the highest fidelity electrically-heated Stirling radioisotope generator built to date. NASA Glenn Research Center (GRC) completed the assembly of the ASRG EU2 in September, 2014 using hardware from the now cancelled ASRG flight development project. The ASRG EU2 integrated the first pair of Sunpower's ASC-E3 Stirling convertors (ASC-E3 #1 and #2) in an aluminum generator housing with Lockheed Martin's Engineering Development Unit (EDU) 4 controller. After just 179 hours of EU2 generator operation, the first power fluctuation occurred on ASC-E3 #1. The first power fluctuation occurred 175 hours later on ASC-E3 #2. Over time, the power fluctuations became more frequent on both convertors and larger in magnitude. Eventually the EU2 was shut down in January, 2015. An anomaly investigation was chartered to determine root cause of the power fluctuations and other anomalous observations. A team with members from GRC, Sunpower, and Lockheed Martin conducted a thorough investigation of the EU2 anomalies. Findings from the EU2 disassembly identified proximate causes of the anomalous observations. Discussion of the team's assessment of the primary possible failure theories, root cause, and conclusions is provided. Recommendations are made for future Stirling generator development to address the findings from the anomaly investigation. Additional findings from the investigation are also discussed.

Optical spectroscopy and optical waveguide fabrication in Eu3+ and Eu3+/Tb3+ doped zinc–sodium–aluminosilicate glasses

International Nuclear Information System (INIS)

Caldiño, U.; Speghini, A.; Berneschi, S.; Bettinelli, M.; Brenci, M.; Pasquini, E.; Pelli, S.; Righini, G.C.

2014-01-01

Optical and spectroscopic properties of 2.0% Eu(PO 3 ) 3 singly doped and 5.0% Tb(PO 3 ) 3 –2.0% Eu(PO 3 ) 3 codoped zinc–sodium–aluminosilicate glasses were investigated. Reddish-orange light emission, with x=0.64 and y=0.36 CIE1931 chromaticity coordinates, is obtained in the europium singly doped glass excited at 393 nm. Such chromaticity coordinates are close to those (0.67,0.33) standard of the National Television System Committee for the red phosphor. When the sodium–zinc–aluminosilicate glass is co-doped with Tb 3+ and Eu 3+ , reddish-orange light emission, with (0.61,0.37) CIE1931 chromaticity coordinates, is obtained upon Tb 3+ excitation at 344 nm. This reddish-orange luminescence is generated mainly by 5 D 0 → 7 F 1 and 5 D 0 → 7 F 2 emissions of Eu 3+ , europium being sensitized by terbium through a non-radiative energy transfer. From an analysis of the Tb 3+ emission decay curves it is inferred that the Tb 3+ →Eu 3+ energy transfer might take place between Tb 3+ and Eu 3+ clusters through a short-range interaction mechanism, so that an electric dipole–quadrupole interaction appears to be the most probable transfer mechanism. The efficiency of this energy transfer is about 62% upon excitation at 344 nm. In the singly doped and codoped glasses multimode optical waveguides were successfully produced by Ag + –Na + ion exchange, and they could be characterized at various wavelengths. -- Highlights: • Reddish-orange light emission can be generated from Tb 3+ and Eu 3+ codoped zinc–sodium–aluminosilicate glasses excited at 344 nm. • The Eu 3+ is sensitized by Tb 3+ through a non-radiative energy transfer. • Highly multimode waveguides can be fabricated by diluted silver–sodium exchange. • This type of AlGaN LEDs pumped glass phosphors might be useful for generation of reddish-orange light

Students measure out their lives, not with coffee spoons, but with grades on examinations. But what exams mean and whether or not they are a bane or a boon is moot. Senior undergraduates (A. Perrella, J. Koenig, and H. Kwon) designed and administered a 15-item survey that explored the contrasting perceptions of both students (n = 526) and faculty members (n = 33) in a 4-yr undergraduate health sciences program. A series of statements gauged the level of agreement on a 10-point scale. Students and faculty members agreed on the value of assessing student learning with a variety of methods, finding new information to solve problems, assessing conceptual understanding and logical reasoning, having assessments with no single correct answer, and having comments on exams. Clear differences emerged between students and faculty members on specific matters: rubrics, student choice of exam format, assessing creativity, and transfer of learning to novel situations. A followup questionnaire allowed participants to clarify their interpretation of select statements, with responses from 71 students and 17 faculty members. All parties strongly agreed that exams should provide a good learning experience that would help them prepare for the future (students: 8.64 ± 1.71 and faculty members: 8.03 ± 2.34).

The investigations carried out on the ..beta..-decay of /sup 155/Eu confirm some decay data of this nucleus and explain a few disagreements on the decay scheme. Using the half-life, the ..beta..-boundary energies and branching ratios, the log ft values of the individual ..beta..-transitions were calculated. Finally, by means of ..beta gamma..-coincidence measurements on the semiconductor spectrometer, the inner partial spectra ..beta../sub 3/ and ..beta../sub 4/ were separated for the first time. Form factor investigations were carried out on these spectra which, despite the high log ft values, confirm the allowed character of these transitions.

The harmonization of banking legislation in the EU

Directory of Open Access Journals (Sweden)

Shkëlqesa Çitaku

2016-03-01

Full Text Available This paper attempts to assess the current legislation of banking in the European Union. The process of unification in Europe is also followed by efforts to harmonize and unify the laws of the member states. In the field of banking industry the precondition for harmonization of laws is the integration of internal market with the free movement of capital. The regulation and supervision of banks in EU still remains fragmented. European member states still have diverse regulations concerning the role of the state. The European Commission has the important function of proposing EU legislation on financial services including banks and ensuring that EU law is properly applied throughout the EU. Banks are considered as a key industry enabling all the economic activities via depositing, crediting and arranging of payments. A number of secondary legislation has been adopted by the EU institutions to harmonize the national banking law of Member States. The principles and objectives set by the European Commission Treaty depend on four EU freedoms with the aim of effective and open market including banks. Therefore it was a continuous process of harmonization of national banking regulation via secondary law since the 70’s.

Zorenko, Y.; Gorbenko, V.; Voznyak, T.; Batentschuk, M.; Osvet, A.; Winnacker, A.

2008-01-01

The paper is devoted to investigation of the processes of excitation energy transfer between the host cations (Tb 3+ ions) and the activators (Ce 3+ and Eu 3+ ions) in single-crystalline films of Tb 3 Al 5 O 12 :Ce,Eu (TbAG:Ce,Eu) garnet which is considered as a promising luminescent material for the conversion of LED's radiation. The cascade process of excitation energy transfer is shown to be realized in TbAG:Ce,Eu: (i) from Tb 3+ ions to Ce 3+ and Eu 3+ ions; (ii) from Ce 3+ ions to Eu 3+ ions by means of dipole-dipole interaction and through Tb 3+ ion sublattice

Zorenko, Yu.; Gorbenko, V.; Grinberg, M.; Turos-Matysiak, R.; Kuklinski, B.

2007-01-01

EuAl 2 O 4 powder phosphor was prepared by solid-state reaction of EuO and Al 2 O 3 oxides in vacuum. The influence of conditions of preparation on spectral lineshape of Eu 2+ emission was analyzed. It was found that the fluorescence spectra of vacuum-prepared EuAl 2 O 4 samples at 300 K present the superposition of three bands peaked at 430, 500 and 528 nm, corresponding to the 4f 6 5d 1 →4f 7 ( 8 S 7/2 ) transition of Eu 2+ ions in the different sites of EuAl 2 O 4 lattice. The luminescence of Eu 2+ centers in EuAl 2 O 4 host was also studied using the high-pressure spectroscopy up to 67 kbar. It was found that the bright green-yellow fluorescence of EuAl 2 O 4 at 300 K in the band peaked at 520-530nm range can be presented by superposition of two Gaussian sub-bands. The different pressure shifts -23 and -27cm -1 /kbar for two sub-bands were found. Such a structure of the emission spectrum was attributed to the existence of two different Eu 2+ centers in the Eu II 2+ sites of EuAl 2 O 4 lattice with higher coordination number

Romeo-Victor Ionescu

2013-05-01

Full Text Available The paper answers at two important questions: Is the EU able to support new adhering processes? and Is the Euro area able to enlarge in 2014? The comparative analysis in the paper covers four economic competitors: EU, USA, China and Japan, and is based on GDP growth rate, unemployment and inflation rates. The second part of the paper deals with an economic forecast during 2015-2016, focused on EU27, Euro area, Croatia and Latvia, in order to discuss the effects of the adhering to EU and Euro area. The results of the two-level analysis are supported by pertinent diagrams and annexes. The analysis uses a neutral statistical database – Eurostat – and dedicated forecast software. The main conclusion of the paper is that the adhering processes from 2013 and 2014 are based on economic and political criteria.

Complexation of Cucurbit(7)uril with Eu(III)

International Nuclear Information System (INIS)

Kar, Aishwarya; Rawat, Neetika; Rao, Ankita; Tomar, B.S.; Nayak, S.K.; Ray, Alok

2014-01-01

Cucurbiturils (CBs) CB(n)s are macrocyclic molecules with carbonyl groups at the portals, which bind cations through ion dipole interactions and the cavity which stabilize hydrophobic moieties. The size of the portal and the volume of the interior cavities of CB(n)s are dependent on the number of glycoluril units present in CBs. CBs are widely used as supramolecular host systems in applications, such as formation of supramolecular hydrogels, drug delivery systems. Though the binding of CBs with organic guest molecules have been studied extensively where as metal complexation studies are very few. In the present work, complexation studies of Cucurbit(7)uril (with seven glycouril units, CB7) with Eu(III) were carried out using fluorescence, UV-vis spectrophotometry. The stability constant for 1:1 complex CB7-Eu(III) complex determined by monitoring the change in CB7 UV- vis absorption spectra on addition of Eu(III) was found to be 2.99 ± 0.08. The fluorescence spectra of increasing ligand to metal ratio exhibited the increase in the intensity ratio of peak at 616 and 592 which is the measure of complexation of Eu(III) with CB7 and was used to deduce the stability constant and the value (2.82 ± 0.07) obtained was in good agreement with that obtained from UV vis spectroscopy. Further, the life time of Eu(III) ion, which increased with CB7 to Eu(III) ratio, was used to deduce number of water molecules around Eu(III) metal ion which were found to decrease from 9 to 3 thereby suggesting inner sphere complexation. The stability constant of CB7 with Eu(III) is one order of magnitude less than CB5, derived in separate study by authors. The smaller cavity of CB5 (2.4 A 0 ) favors its interactions with Eu(III) ion of comparable diameter (2.16 A 0 ) leading to higher stability constant compared to CB7 (5.4 A 0 ) having larger cavity

A spectroscopic analysis of sodium germanate glasses activated with Eu{sup 3+}, Tb{sup 3+} and Eu{sup 3+}/Tb{sup 3+} is performed from their photoluminescence spectra and decay times. In the Eu{sup 3+}-singly doped glass reddish-orange light emission, with x=0.64 and y=0.35 CIE1931 chromaticity coordinates, is obtained upon Eu{sup 3+} excitation at 393 nm. Such chromaticity coordinates are close to those (0.67, 0.33) proposed by the National Television Standard Committee for the red phosphor. When the sodium germanate glass is co-doped with Tb{sup 3+} and Eu{sup 3+} greenish-yellow light emission, with (0.41, 0.46) CIE1931 chromaticity coordinates, is obtained upon Tb{sup 3+} excitation at 344 nm. Such greenish-yellow luminescence is due mainly to the terbium {sup 5}D{sub 4}→{sup 7}F{sub 6,5} and europium {sup 5}D{sub 0}→{sup 7}F{sub 1,2} emissions, Eu{sup 3+} being sensitized by Tb{sup 3+} through a non-radiative energy transfer. The non-radiative nature of this energy transfer is inferred from the increase in the decay rate of the Tb{sup 3+} emission when the glass is co-doped with Eu{sup 3+}. From an analysis of the Tb{sup 3+} emission decay time curves it is inferred that such energy transfer might take place between Tb{sup 3+} and Eu{sup 3+} clusters through a short-range interaction mechanism. - Highlights: • Sodium germanate glasses are optically activated with Eu{sup 3+} (GNE) and Tb{sup 3+}/Eu{sup 3+} (GNTE). • Reddish-orange light (0.64, 0.35) is generated by GNE pumped with 393 nm light. • Greenish-yellow light (0.41, 0.46) is generated by GNTE pumped with 344 nm light. • Non-radiative energy transfer Tb{sup 3+}→Eu{sup 3+} takes place in GNTE.

Investing EU ETS auction revenues into energy savings

The overall objective of this study is to analyse the effects of using EU ETS auction revenues to stimulate investments in energy savings in three key target sectors, i.e. Households, Tertiary and Industry (including both ETS and non-ETS industrial installations). The scenarios used refer basically to the situation before the recent agreement on the Energy Efficiency Directive (EED) and include (a mixture of) different policy options to enhance energy savings in the target sectors, in particular (1) reducing the ETS cap, (2) introducing an Energy Efficiency Obligation (EEO) for energy suppliers or distributors, and/or (3) using ETS auction revenues to support additional (private) investments in raising energy efficiency. In order to meet this objective a variety of different policy scenarios have been defined and analysed by means of the 'Energy-Environment-Economy Model for Europe (E3ME)'. The study presents and discusses a large variety of scenario modelling results by the year 2020 at the EU27 level. These results refer to, among others, energy savings, GHG emissions, the ETS carbon price, household electricity bills and to changes in some macro- or socio-economic outcomes such as GDP, inflation, employment or international trade. Finally, the study discusses some policy findings and implications, including options to enhance the effectiveness of some EE policies, in particular those having a potential adverse effect on the ETS carbon price.

EU energy-intensive industries and emissions trading: losers becoming winners?

Energy Technology Data Exchange (ETDEWEB)

Wettestad, Joergen

2008-11-15

The EU Emissions Trading System (ETS) initially treated power producers and energy-intensive industries similarly, despite clear structural differences between these industries regarding pass through of costs and vulnerability to global competition. Hence, the energy-intensive industries could be seen as losing out in the internal distribution. In the January 2008 proposal for a reformed ETS post-2012, a differentiated system was proposed where the energy-intensive industries come out relatively much better. What is the explanation for the change taking place? Although power producers still have a dominant position in the system, the increasing consensus about windfall profits has weakened their standing. Conversely, the energy-intensive industries have become better organised and more active. This balance shift is first and foremost noticeable in several important EU-level stake holder consultation processes. Energy-intensive industries have, however, also successfully utilised the national pathway to exert influence on Brussels policy-making. Finally, growing fear of lax global climate policies and related carbon leakage has strengthened the case of these industries further. The latter dimension indicates that although energy-intensive industries have managed to reduce internal distribution anomalies, external challenges remain. (author). 9 refs

Anthropogenic Nitrogen and Phosphorus Emissions and Related Grey Water Footprints Caused by EU-27′s Crop Production and Consumption

Full Text Available Water is a prerequisite for life on our planet. Due to climate change and pollution, water availability for agricultural production, industry and households is increasingly put at risk. With agriculture being the largest water user as well as polluter worldwide, we estimate anthropogenic nitrogen and phosphorus emissions to fresh water related to global crop production at a spatial resolution level of 5 by 5 arc min and calculate the grey water footprints (GWF related to EU-27′s crop production. A multiregional input-output model is used to trace the the GWF embodied in the final consumption of crop products by the EU-27. The total GWF related to crop production in the EU-27 in 2007 was 1 × 1012 m3/year. Spain contributed about 40% to this total. Production of cereals (wheat, rice and other cereals take the largest share, accounting for 30% of the GWF, followed by fruits (17%, vegetables (14%, and oil crops (13%. The total agricultural GWF of the EU-27 related to crop consumption was 1830 billion m3/year, which is 3700 m3/year per capita on average. Overall, the EU-27 was able to externalize about 41% of the GWF to the rest of the world through imports of crop products.

The photoluminescence/excitation (PL/E) spectroscopy of Eu-implanted GaN

KAUST Repository

O'Donnell, Kevin Peter

2011-05-01

Several distinct luminescent centres form in GaN samples doped with Eu. One centre, Eu2, recently identified as the isolated, substitutional Eu impurity, EuGa, is dominant in ion-implanted samples annealed under very high pressures (1 GPa) of N2. According to structural determinations, such samples exhibit an essentially complete removal of lattice damage caused by the implantation process. A second centre, Eu1, probably comprising EuGa in association with an intrinsic lattice defect, produces a more complex emission spectrum. In addition there are several unidentified features in the 5D0 to 7F2 spectral region near 620 nm. We can readily distinguish Eu1 and Eu2 by their excitation spectra, in particular through their different sensitivities to above-gap and below-gap excitation. The present study extends recent work on photoluminescence/ excitation (PL/E) spectroscopy of Eu1 and Eu2 to arrive at an understanding of these mechanisms in terms of residual optically active defect concentrations. We also report further on the \\'host-independent\\' excitation mechanism that is active in the case of a prominent minority centre. The relevance of this work to the operation of the red GaN:Eu light-emitting diode is discussed. © 2010 Elsevier B.V. All rights reserved.

Full Text Available VAT is one of the newest tools of the global economy and is widely adopted in most of the countries. For EU Member States is required not only the existence of VAT, but also that its main characteristics to be uniformly implemented. This should facilitate intra-Community transactions, but in practice does not as there are many local variations which can lead to costly errors and penalties. The objective of this paper is to collate data about the main characteristics of VAT in EU Member States and to highlight the key differences between them. This survey shows that there continue to be opportunities and risks for businesses trading cross border, as a result of differences in application of Community legislation on VAT. This led to the necessity of VAT reform. On this basis, the Commission adopted on the end of the last year a Communication on the future of VAT. This sets out the fundamental characteristics that must underlie the new VAT regime, and priority actions needed to create a simpler, more efficient and more robust VAT system in the EU.

A multi-level analysis of the EU linking directive process: the controversial connection between EU and global climate policy

Energy Technology Data Exchange (ETDEWEB)

Flaam, Karoline Haegstad

2007-10-15

Despite initial scepticism in the EU towards the Kyoto Protocol's project mechanisms (the CDM and JI), the 'Linking Directive' was adopted in October 2004, connecting the EU emissions trading scheme with the project mechanisms. Not only was the Linking Directive settled remarkably quickly, the decision-making process also left a more liberal text, with fewer restrictions on the use of the project mechanisms, as compared to the initial directive proposal. This report examines possible explanations to this puzzle, evaluating whether Member State preferences, EU institutions or external influence from the climate regime best can contribute to understanding the process. On the basis of the analysis of written sources stemming from the decision-making process, as well as seven in-depth interviews, the report finds that Member State preferences were the main driver in the Linking Directive process. This gives support to the intergovernmentalist mantra, that Member States are the main decision-makers in the EU. It also challenges much recent research claiming that EU policy-making is increasingly being taken out of the hands of the nation-state and into supranational actors such as the Commission and the European Parliament.

A pressure-induced valence transition has attracted much attention in Eu-compounds. Among them, EuRh2Si2, EuNi2Ge2, and EuCo2Ge2 reveal the valence transition around 1, 2, and 3 GPa, respectively. We have succeeded in growing single crystals of EuT2X2 (T: transition metal, X: Si, Ge) and studied electronic properties under pressure. EuRh2Si2 indicates a first-order valence transition between 1 and 2 GPa, with a large and prominent hysteresis in the electrical resistivity. At higher pressures, the first-order valence transition changes to a cross-over regime with an intermediate valence state. Tuning of the valence state with pressure is reflected in a drastic change of the temperature dependence of the electrical resistivity in EuRh2Si2 single crystals. Effect of pressure on the valence states on EuRh2Si2, EuIr2Si2, EuNi2Ge2, and EuCo2Ge2, as well as an isostructural related compound EuGa4, are reviewed.

Ukraine, EU and Russia: soft power versus Realpolitik?

2014-05-01

Full Text Available The relationship between the European Union (EU and Ukraine began in 1998 with the signature of the Partnership and Cooperation Agreement. Afterwards, in 2003 Ukraine joined the European Neighbourhood Policy and in 2004 EU was already the major trade partner with Ukraine, bigger than Russia. Anticipating the approach of former soviet republics towards Euro Atlantic structures and the foreseen loss of influence in its near abroad, Putin’s Russia launched in 2011 the Eurasian Economic Union, an economic bloc formed by some of the Russia’s former satellite States - Belarus and Kazakhstan – and through a carrot and stick policy tried to attract also Ukraine and Kyrgyzstan, in order to thwart the Chinese economic development and to impose itself in the regional and global markets. In November 2013, during the 3rd EU’s Eastern Partnership Summit, in Vilnius, Lithuania, Ukraine’s President, Viktor Yanukovych surprised the world refusing to sign the Commercial Agreement with EU, turning back to a EU possible integration. On the other hand, Russia offered to reduce the natural gas rates plus a fifteen billion dollars loan, throwing Ukraine in a quasi civil war, and leaving EU and Russia on opposite sides. Considering this situation what to expect from Ukraine? To continue being a Russian satellite or head towards the Euro Atlantic geopolitical space? This paper intents to analyse the actual situation in Ukraine following Barry Buzan’s approach of multidimensional security, focusing on the different postures assumed by each one of the actors - EU and Russia - which have been between complementarity and division. The scope of the analysis is to contribute to the academic debate about security dynamics between EU, Russia and Ukraine during the post-USSR period, arguing that in the geopolitical dispute for the post-soviet space where Ukraine is integrated, the Russian Realpolitik prevails the EU soft power.

In most Eu 3+ activated phosphors, only red luminescence from the 5 D 0 is obtainable, and efficiency is limited by concentration quenching. Herein we report a new phosphor of Ca 4 LaO(BO 3 ) 3 :Eu 3+ (CLBO:Eu) with advanced photoluminescence properties. The yellow luminescence emitted from the 5 D 1,2 states is not thermally quenched at room temperature. The relative intensities of the yellow and red emission bands depend strongly on the Eu 3+ doping concentration. More importantly, concentration quenching of Eu 3+ photoluminescence is absent in this phosphor, and the stoichiometric compound of Ca 4 EuO(BO 3 ) 3 emits stronger luminescence than the Eu 3+ doped compounds of CLBO:Eu; it is three times stronger than that of a commercial red phosphor of Y 2 O 3 :Eu 3+ . Another beneficial phenomenon is that ligand-to-metal charge transfer (CT) transitions occur in the long UV region with the lowest charge transfer band (CTB) stretched down to about 3.67 eV (∼330 nm). The CT transitions significantly enhance Eu 3+ excitation, and thus result in stronger photoluminescence and promote trapping of excitons for persistent afterglow emission. Along with structure characterization, optical spectra and luminescence dynamics measured under various conditions as a function of Eu 3+ doping, temperature, and excitation wavelength are analyzed for a fundamental understanding of electronic interactions and for potential applications.

Impact of Transposition of the Directive 2013/34/EU into the National Laws of EU Member States Emphatically V4

Selective separation of Eu3+ using polymer-enhanced ultrafiltration

International Nuclear Information System (INIS)

Norton, M.V.

1994-03-01

A process to selectively remove 241 Am from liquid radioactive waste was investigated as an actinide separation method applicable to Hanford and other waste sites. The experimental procedures involved removal of Eu, a nonradioactive surrogate for Am, from aqueous solutions at pH 5 using organic polymers in conjunction with ultrafiltration. Commercially available polyacrylic acid (60,000 MW) and Pacific Northwest Laboratory's (PNL) synthesized E3 copolymer (∼10,000 MW) were tested. Test solutions containing 10 μg/mL of Eu were dosed vath each polymer at various concentrations in order to bind Eu (i.e., by complexation and/or cation exchange) for subsequent rejection by an ultrafiltration coupon. Test solutions were filtered with and without polymer to determine if enhanced Eu separation could be achieved from polymer treatment. Both polymers significantly increased Eu removal. Optimum concentrations were 20 μg/mL of polyacrylic acid and 100 μg/mL of E3 for 100% Eu rejection by the Amicon PM10 membrane at 55 psi. In addition to enhancement of removal, the polymers selectively bound Eu over Na, suggesting that selective separation of Eu was possible. This suggests that polymer-enhanced ultrafiltration is a potential process for separation of 241 Am from Hanford tank waste, further investigation of binding agents and membranes effective under very alkaline and high ionic strength is warranted. This process also has potential applications for selective separation of toxic metals from industrial process streams

Solar Energy: Incentives to Promote PV in EU27

Directory of Open Access Journals (Sweden)

María del P. Pablo-Romero

2013-11-01

Full Text Available The growth in the use of renewable energies in the EU has been remarkable. Among these energies is PV. The average annual growth rate for the EU-27 countries in installed PV capacity in the period 2005-2012 was 41.2%. While the installed capacity of PV has reached almost 82 % of National Renewable Energy Action Plan (NREAP targets for the EU-27 countries for 2020, it is still far from being used at its full potential. Over recent years, several measures have been adopted in the EU to enhance and promote PV. This paper undertakes a complete review of the state of PV power in Europe and the measures taken to date to promote it in EU-27. 25 countries have adopted measures to promote PV. The most widespread measure to promote PV use is Feed- in Tariffs. Tariffs are normally adjusted, in a decreasing manner, annually. Nevertheless, currently, seven countries have decided to accelerate this decrease rate in view of cost reduction of the installations and of higher efficiencies. The second instrument used to promote PV in the EU-27 countries is the concession of subsidies. Nevertheless, subsidies have the disadvantage of being closely linked to budgetary resources and therefore to budgetary constraints. In most EU countries, subsidies for renewable energy for PV are being lowered. Twelve EU-27 countries adopted tax measures. Low-interest loans and green certificate systems were only sparingly used.

Full Text Available This article provides a critical review of the “terms” of the ongoing EU enlargement, in the light of the European public interest. The European public interest ought to include the prospective (Central European members, within a perspective of an enlarged Union in 2010, or so. The following forms a personalised summary of a major report published (in Dutch in September 2001 by the WRR in The Hague (a think-tank, formally under the Dutch Prime Minister, but by statute fully independent. The author was one of the lead-writers of this report. The present article merely focuses on the policy recommendations of the report. It is hoped that these kinds of critical analyses will help to stimulate solid policy debate on the EU in Romania, on the road to EU membership. The article discusses why the notion of a “core-acquis” would improve the enlargement strategy; the application of the core acquis to the internal market, environment and justice and home affairs; judicial and administrative capacity; accession to “euro-land”; the rapid reform of the CAP; a reform of “cohesion” approaches; and a note on the EU budgetary implications.

Streimikiene, Dalia; Sivickas, Gintautas

2008-11-01

The article deals with indicators framework to monitor implementation of the main EU (European Union) directives and other policy documents targeting sustainable energy development. The main EU directives which have impact on sustainable energy development are directives promoting energy efficiency and use of renewable energy sources, directives implementing greenhouse gas mitigation and atmospheric pollution reduction policies and other policy documents and strategies targeting energy sector. Promotion of use of renewable energy sources and energy efficiency improvements are among priorities of EU energy policy because the use of renewable energy sources and energy efficiency improvements has positive impact on energy security and climate change mitigation. The framework of indicators can be developed to establish the main targets set by EU energy and environmental policies allowing to connect indicators via chain of mutual impacts and to define policies and measures necessary to achieve established targets based on assessment of their impact on the targeted indicators representing sustainable energy development aims. The article discusses the application of indicators framework for EU sustainable energy policy analysis and presents the case study of this policy tool application for Baltic States. The article also discusses the use of biomass in Baltic States and future considerations in this field.

Lattice dynamic behaviors of Eu and Fe atom in the complexes were investigated by Moessbauer spectroscopy. By {sup 151}Eu-Moessbauer spectrum and parameters of new complexes, bpy complex showed the largest quadrupole splitting value, indicating bad symmetry of Eu ligand in the environment. Molecular structure of napy, bpy and phen complex were shown. These complexes are consisted of Eu atom coordinated with ligand and water molecule, of which (Fe(CN){sub 6}){sup 3-} ion formed one dimentional polymer chain and naphthyridines formed stacking structure. New complexes were observed by {sup 57}Fe-Moessbauer spectroscopy, too. The quadrupole splitting values were very different each other, indicating change of symmetry of Fe atom in the environment and three valence low spin state of Fe in the complex. (S.Y.)

The site and local structure of activator Eu{sup 2+} in phosphor Ca{sub 10−x}(PO{sub 4}){sub 6}Cl{sub 2}:xEu{sup 2+} is investigated by experiment measurements, first-principle calculations and XAFS simulations. From first-principle calculations, the “local” structure [bond length L(M–O)≤R(M{sup 2+})+R(O{sup 2−})] of host shows a significant deformation (expansion) when Ca{sup 2+} is substituted by Eu{sup 2+}, and Eu{sup 2+} should prefer 6h site to 4f site in the host. The d→f emission of Eu{sup 2+} at 4f site should show a longer wavelength than that of Eu{sup 2+} at 6h site. The XAFS measurement and simulations suggest that the Eu{sup 2+} in our Ca{sub 9.9}(PO{sub 4}){sub 6}Cl{sub 2}:0.1Eu{sup 2+} sample mainly locates at 6h site. In the emission spectrum, two emission profiles of Ca{sub 9.9}(PO{sub 4}){sub 6}Cl{sub 2}:0.1Eu{sup 2+} sample are obtained and assigned. The major one (2.71 eV≈456 nm) should be the emission of Eu{sup 2+} at 6h site. The minor one (2.61 eV≈465 nm) should be that of Eu{sup 2+} at 4f site. - Graphical abstract: The d→f emission of Eu{sup 2+} in Ca{sub 9.9}(PO{sub 4}){sub 6}Cl{sub 2}:0.1Eu{sup 2+} can be assigned as: emission profile at 2.71 eV and 2.61 eV are Eu{sup 2+} at 6h and 4f site, respectively. Display Omitted - Highlights: • Eu{sup 2+} in Ca{sub 10−x}(PO{sub 4}){sub 6}Cl{sub 2}:xEu{sup 2+} causes deformation to “local” structure. • Eu{sup 2+} should prefer 6h site to 4f site in the host from energy aspect. • Emission at 2.71 eV and 2.61 eV should be Eu{sup 2+} at 6h and 4f site.

In this work, structural, thermal and optical properties of Eu{sup 3+} doped TeO{sub 2}-La{sub 2}O{sub 3}-TiO{sub 2} glass were investigated. The differential scanning calorimetry (DSC) measurements reveal an important stability factor {Delta}T=143.52 K, which indicates the good thermal and mechanical stabilities of tellurite glass. From the absorption spectrum, the optical band gap was found to be direct with E{sub g}=3.23 eV. The temperature dependences of photoluminescence (PL) properties of Eu-doped and Eu-Tb codoped tellurite glass are investigated. As the temperature increases from 7 to 300 K, both the PL intensity and the PL lifetime relative to the {sup 5}D{sub 2}{yields}{sup 7}F{sub 0} are nearly constant below 230 K and then an enhancement takes place. This anomalous feature is attributed to the thermally activated carrier transfer process from charged intrinsic defects states to Eu{sup 3+} energy levels. By co-doping tellurite glasses with Eu and Tb, a strong Eu{sup 3+} PL enhancement is shown due to excitation transfer from Tb{sup 3+} and intrinsic defects to Eu ions. - Highlights: > TeO{sub 2}-La{sub 2}O{sub 3}-TiO{sub 2} glass doped Eu{sup 3+} with good thermal stability elaborated. > PL evolution of Eu{sup 3+} with temperature shows a non-conventional behavior. > Thermally activated carrier transfer from intrinsic defects states to Eu{sup 3+} shown. > Strong Eu{sup 3+} PL enhancement is shown in Eu-Tb codoped glass.

Involving the citizens. Radioactive waste management and the EU

International Nuclear Information System (INIS)

Ferraro, Gianluca

2014-01-01

The European Union (EU) has been often criticized for its democratic deficit, which has been studied in the academic literature at multiple levels: in the polity (macro-level), the institutions (meso-level) and the policies (micro-level) of the EU. The paper presents counterarguments in favour of the democratic nature of the EU and focuses on the micro-level, particularly the process of implementation of EU policies. Policy implementation and the democratic involvement of citizens are discussed with regard to radioactive waste management and the Directive 2011/70/EURATOM. The Directive's clause on transparency and the recent development of a centre of knowledge for public participation in energy policy implementation by the European Commission (EC) are expression of the democratic nature of the EU and provide further counterarguments to the claim of democratic deficit.

Exchange-rate policy in eastern Europe and EU integration

Jozef M. Van Brabant

2001-09-01

Full Text Available The paper examines potential conflicts between rapid EU integration of economies in transition (EiTs and their pursuing catch-up by focusing on exchange-rate policies. After justifying the proposed inquiry, official pronouncements on ER policies that EUcandidates are expected to pursue in the run-up to and upon their accession are summarized, and the salient features of recent debates on ER regimes recalled. Inasmuch as EiTs must modernize and reconcile this obligation with EU membership, in spite of the EU's cohesion experience, the paper combines real and nominal convergence issues with institutional changes upon EU accession to draw a novel perspective on the desirable postaccession transition regime for EiTs with a fairly active ER policy and the EU's cohesion strategy. Core components of such a strategy are advocated.

Turkey’s Population Dynamics As A Candidate Country For EU Membership

Directory of Open Access Journals (Sweden)

Harun Uçak

2011-01-01

Full Text Available Literally, it has been accepted that one of the major obstacles to Turkey’s EU membership is in population term. There has not been any enlargement process as large as Turkey’s population as a single state in EU history before. The enlargement in 2004 which includes 10 states involved 74 million people as whole member states while Turkey’s population is 72 million inhabitants in 2007 data which is only lower than Germany’s population in all EU member states. Thus, Turkey's accession would be different from previous enlargements because of the combined impact of high population. This study compares the population dynamics, working conditions, minimum wage rates and main macroeconomic indicators between Turkey and EU member states. Turkey has young generations compared to EU countries. In the comparison of age groups proportion in total population, 0-19 age group %21,9 in EU 27 and %36,5 in Turkey, 20-39 age group is %28 in EU 27 and %34,3 in Turkey, 40-59 age group is %27,9 in EU and %20,9 in Turkey, 60 and above age group is %22,1 in EU and %9,5 in Turkey. Thus, population dynamics of Turkey could make a contribution to offsetting the ageing of EU 27 societies if the membership would occur in the future. However, minimum wage rates in Turkey are lower than many EU member states but generally higher than EU member states located in Central and Eastern Europe. Thus, immigration possibilities from Turkey can be expected to Western European Countries, but not the same direction to Central and Eastern Europe Countries. Furthermore, the process in macroeconomic indicators will be a determinant in immigration expectations while Turkey’s GDP has been grown faster than EU level recently.

EU Action against Climate Change. EU emissions trading. An open scheme promoting global innovation

International Nuclear Information System (INIS)

2005-01-01

The European Union is committed to global efforts to reduce the greenhouse gas emissions from human activities that threaten to cause serious disruption to the world's climate. Building on the innovative mechanisms set up under the Kyoto Protocol to the 1992 United Nations Framework Convention on Climate Change (UNFCCC) - joint implementation, the clean development mechanism and international emissions trading - the EU has developed the largest company-level scheme for trading in emissions of carbon dioxide (CO2), making it the world leader in this emerging market. The emissions trading scheme started in the 25 EU Member States on 1 January 2005

Full Text Available The problems of renewable energy and regional development have gained a global dimension, as well as the concerns about the economic growth. Therefore, this study investigates the issue of managing renewable energy in the EU10 region, within the context of recovery and anticipated growth of the region. The findings of this study disclose that an important source of economic growth in the EU10 region's countries may be to start some new investments in renewable energy. In order to develop the field of renewable energy may be used EU funds, and may be envisaged different public-private partnership models, that may contribute to lower societal costs and increased deployment rates. The study was conducted by combining a wide variety of sources, such as statistics, reports and articles. The results reported in this study could be used for further research in the area of implementing green energy projects in the EU10 region. Another direction for further research could be to identify the most attractive countries for different renewable energy investment projects in the EU10 region.

The Government has instructed the Swedish Energy Agency and the Swedish Environmental Protection Agency to put forward a proposal for how the EU Emissions Trading Scheme (EU ETS) should be developed after 2012, subject to the overall objective of continuing to reduce emissions with the aim of achieving the long-term objectives of the Convention on Climate Change. In its Council Conclusions (7619/1/05) the EU has interpreted the long-term objectives of the Convention on Climate Change as aiming to achieve emission reductions of 15-30 % in the industrialised countries by 2020. According to Council Conclusions (13435/05), the EU has also decided that the Emissions Trading Scheme should continue after 2012. The starting point for this report is that, after 2012, the Scheme will be a key instrument in achieving cost-efficient emission reductions, not only within the EU but also globally, and regardless of whether, with effect from 2013, the Scheme has become a part of an international climate regime, or is serving as a transition to some future new international climate regime. The purpose of this report is to provide a proposal for how the Emissions Trading Scheme should be developed after 2012. The aim is to construct a system that helps to reduce global emissions of greenhouse gases (maintaining climate integrity), that assists measures being taken where they are cheapest (cost efficiency), that is accepted by parties concerned and by the general public (confidence inspiring), and which does not adversely affect the competitiveness of business or industry (competition-neutral). The Agencies recommend that Sweden should adopt the following standpoints concerning development of the EU Emissions Trading Scheme after 2012. (Recommended changes to the system presuppose a harmonised implementation throughout the EU.): In connection with international negotiations, Sweden should press for the Emissions Trading Scheme to be developed in such a way as to make it possible to

Synthesis and photocatalytic activity of Eu3+-doped nanoparticulate TiO2 sols and thermal stability of the resulting xerogels

2014-01-01

The synthesis of nanoparticulate TiO 2 sols without and with Eu 3+ doping (1, 2, or 3 mol%) by the colloidal sol–gel method in aqueous media was investigated, with emphasis on the effect of the Eu 3+ doping on the peptization time and rheological properties of the sols. It was found that the addition of Eu 3+ increasingly retards the peptization process, and also results in sols with greater aggregate sizes which are therefore more viscous, although in all cases the distributions of aggregate sizes are unimodal and the flow behavior is Newtonian. The shifting of the isoelectric point of the sols toward greater pH with increasing Eu 3+ doping indicates that the aforementioned trends are due to the chemical adsorption of europium ionic complexes in the form of solvated species. Furthermore, the effect of Eu 3+ doping on the ultraviolet–visible spectrum and photocatalytic activity of the peptized sols was also explored. It was found that the Eu 3+ doping increasingly shifts slightly the absorption edge from the ultraviolet to the visible range, and that its effect on the photocatalytic activity is certainly complex because this is enhanced only if the Eu 3+ cations have some electronic transition (charge transfer transition or transitions between the ground state and the excited states) at the wavelength of the incident radiation, in which case the photocatalytic activity first increases with increasing Eu 3+ content and then decreases perhaps due to occurrence of Eu–Eu interactions or simply to the greater aggregation state. Finally, the influence of the Eu 3+ doping on the thermal stability of the nanoparticulate xerogels resulting from the drying of the peptized sols was also examined by X-ray thermo-diffractometry together with transmission electron microscopy, selected area electron diffractometry, and X-ray energy-dispersive spectrometry. It was found that although the xerogels crystallize all as anatase phase, this is increasingly more thermally stable

In its fight against climate change the EU is committed to reducing its overall greenhouse gas emissions to at least 20% below 1990 levels by 2020. To meet this commitment, the EU builds on segmented market regulation with an EU-wide cap-and-trade system for emissions from energy-intensive installations (ETS sectors) and additional measures by each EU Member State covering emission sources outside the cap-and-trade system (the non-ETS sector). Furthermore, the EU has launched additional policy measures such as renewable energy subsidies in order to promote compliance with the climate policy target. Basic economic reasoning suggests that emission market segmentation and overlapping regulation can create substantial excess costs if we focus only on the climate policy target. In this paper, we evaluate the economic impacts of EU climate policy based on numerical simulations with a computable general equilibrium model of international trade and energy use. Our results highlight the importance of initial market distortions and imperfections as well as alternative baseline projections for the appropriate assessment of EU compliance cost. (author)

The European Union (EU) has been often criticized for its democratic deficit, which has been studied in the academic literature at multiple levels: in the polity (macro-level), the institutions (meso-level) and the policies (micro-level) of the EU. The paper presents counter-arguments in favour of the democratic nature of the EU and focuses on the micro-level, particularly the process of implementation of EU policies. Policy implementation and the democratic involvement of citizens are discussed with regard to radioactive waste management and the Directive 2011/70/EURATOM. The Directive's clause on transparency and the recent development of a centre of knowledge for public participation in energy policy implementation by the European Commission (EC) are expression of the democratic nature of the EU and provide further counter-arguments to the claim of democratic deficit.

2014-01-01

The presentation was oriented to critical review of the lessons learned from the European Union (EU) Stress Test focusing on NPP robustness against external hazards. These lessons addressed: - organization of the stress tests, - scope and objectives of the stress tests, - peer review findings, recommendations and implications on the design in the area of external hazards, - further studies recommended in the area of external hazards and PSA, - relevant research areas identified by the SNETP Task Group in response to Fukushima accident. Some important conclusions were made in the final part of the presentation: - Vulnerability to the Fukushima Dai-ichi reactor accidents caused by external hazards and including their secondary effects was underestimated, - Lessons learned from Fukushima Dai-ichi reactor accidents, from the EU Stress Test and from peer reviews are to be reflected in safety improvements of operating plants and considered in new designs, - while no completely new phenomena were revealed from the Fukushima Dai-ichi reactor accidents, improvements in specific research areas (including external hazards and use of PSA) should be considered with high priority

In order to perform our empirical analysis, we estimate different growth models restricting the time frame to the first 15 years of the Euro - from 1999 to 2013. We find...... a positive impact of EU membership on economic growth, but no impact of being part of the EZ, except during the financial crisis, when the EZ has a negative impact on growth amongst its members. Considering the heated political debate related to the Brexit referendum, our results favour a “yes” to the EU...

Sm{sup 3+} singly doped NaY(WO{sub 4}){sub 2} and Sm{sup 3+}, Eu{sup 3+} co-doped NaY(WO{sub 4}){sub 2} phosphors have been synthesized by molten salt method. The crystal structure and morphology were characterized by means of X-ray powder diffraction (XRD) and field emission scanning electron microscopy (FE-SEM). In Sm{sup 3+} singly doped NaY(WO{sub 4}){sub 2} phosphors, the suitable doping concentration was proved. In Sm{sup 3+}, Eu{sup 3+} co-doped NaY(WO{sub 4}){sub 2} phosphors, the energy transfer from Sm{sup 3+} to Eu{sup 3+} is confirmed by the luminescent spectra. A strong absorption line at 405 nm can be generated from {sup 6}H{sub 5/2}-{sup 4}K{sub 11/2} ({sup 4}F{sub 7/2}) transition of Sm{sup 3+} in Sm{sup 3+}, Eu{sup 3+} co-doped NaY(WO{sub 4}){sub 2} phosphors, which is suitable for the emission of the near-ultraviolet light-emitting diodes. The energy transfer efficiency, energy transfer rate and average distance between Sm{sup 3+} and Eu{sup 3+} in the NaY(WO{sub 4}){sub 2}:Sm{sup 3+}, Eu{sup 3+} phosphors have been calculated based on the fluorescent dynamic analysis. Finally, the energy transfer mechanism between Sm{sup 3+} and Eu{sup 3+} is confirmed, the energy transfer occurs between {sup 4}G{sub 5/2} state of Sm{sup 3+} ions and {sup 5}D{sub 0} state rather than {sup 5}D{sub 1} state of Eu{sup 3+} ions.

The Federal Features of the EU: Lessons from Canada

Directory of Open Access Journals (Sweden)

Amy Verdun

2016-08-01

Full Text Available There has been a rise and fall in interest in federalism in the context of European integration. This article assesses the federal nature of the EU. It draws in particular on the work of Michael Burgess who has been one of the key thinkers on this issue. Because there are many types of ‘federalisms’ available across the globe, it is helpful to make a comparison with another political system to offer a base line. In this article I explore to what extent the EU already has federal features. With the help of the work of Burgess I seek to look beyond the specific characteristics of the EU and reflect on how a comparison with this other polity can offer us insights into what is going on within the EU political system. Drawing on the comparison with Canada, I seek to identify the characteristics of the EU that are already those of a federation. Therefore, the guiding question of this article is: compared to Canada, what particular features does the EU have that reminds us of a federation and what features is it still lacking? It finds that the EU has a considerable amount of federal features (federation, but that a federal tradition, a federal ideology and advocacy to a federal goal (federalism are mostly absent.

(Sr, Ca, Ba)Al2O4:Eu2+, Dy3+ phosphors were prepared via a high temperature solid-state reaction method. The correlation of phase structure, optical properties and lifetimes of the phosphors are investigated in this work. For the (Sr, Ca)Al2O4:Eu2+, Dy3+ phosphors, the different phase formation from monoclinic SrAl2O4 phase to hexagonal SrAl2O4 phase to monoclinic CaAl2O4 phase was observed when the Ca content increased. The emission color of SrAl2O4:Eu2+, Dy3+ phosphors varied from green to blue. For the (Sr, Ba)Al2O4:Eu2+, Dy3+ phosphors, different phase formation from the monoclinic SrAl2O4 phase to the hexagonal BaAl2O4 phase was observed, along with a shift of emission wavelength from 520 nm to 500 nm. More interestingly, the decay time of SrAl2O4:Eu2+, Dy3+ changed due to the different phase formations. Lifetime can be dramatically shortened by the substitution of Sr2+ with Ba2+ cations, resulting in improving the performance of the alternating current light emitting diode (AC-LED). Finally, intense LEDs are successfully obtained by combining these phosphors with Ga(In)N near UV chips. PMID:29057839

2018-05-01

The red-emitting Sr2Si5N8:Eu2+ phosphors have been synthesized in a new facile process using (oxy)nitride precursors by inductive calcination under N2 atmosphere at ordinary pressure. Different from the prevailing methods, lower cost raw materials, simpler pretreatment, without harsh conditions and a shorter reaction time are achieved. It was found that red-emitting Sr2Si5N8:Eu2+ phosphors were synthesized with high crystallinity and purity after 1 h inductive calcination. The formation mechanism was characterized by XRD, SEM, TEM and Fluorescence microscopy. It was demonstrated that a hexagonal mesophase of Sr-doped α-Si3N4 was primarily formed in the reaction process, which transformed into the final product of the orthorhombic Sr2Si5N8:Eu2+ phosphors. During the reaction process, the color of the samples transforms from greenish-yellow to orange and eventually to red. The as-prepared phosphors have a wide excitation in the range of 250 ∼ 570 nm which matches blue light chips and give a red-light emission peaking at 610 nm. The results indicate a promising prospect for a simple, efficient and inexpensive way to prepare Sr2Si5N8:Eu2+ phosphors for blue/UV-based warm-white LEDs and other fluorescent applications.

Eu 3+ doped TiO 2 nanoparticles were prepared by urea hydrolysis in ethylene glycol medium at low temperature of 150 deg. C. X-ray diffraction study showed that anatase phase of tetragonal structure was formed below 500 deg. C; and above this temperature, additional peaks due to rutile phase were also observed. From luminescence study, it was found that as prepared nanoparticles showed the enhanced luminescence intensity due to energy transfer from host to europium ions. However, photoluminescence from these nanoparticles was found to disappear when the samples were heated above 900 deg. C. We established the origin of the reduction in the luminescence intensity from Eu 3+ when doped in TiO 2 and heated at 900 deg. C. Based on detailed studies at different heat-treatment temperatures using techniques such as X-ray diffraction, X-ray photoelectron spectroscopy, electron paramagnetic resonance, Raman spectroscopy, and Moessbauer spectroscopy, it has been established that formation of Eu 2 Ti 2 O 7 phase, wherein Eu 3+ ions occupy high symmetric environment (D 3d ) and also reduced distance between Eu 3+ and Eu 3+ ions is responsible for the decrease/loss in the luminescence intensity.

Meeting Europe's resource challenge within and beyond EU borders

The European Union (EU) faces a serious resource challenge. It is dependent on external sources of energy and other raw materials, and this makes it vulnerable to resource availability and price fluctuations. If not managed, this could have serious implications for Europe and its competitiveness, for public and private sectors, for citizens and for overall European well-being. The EU takes environmental challenges seriously, at least on paper, and has developed a number of internal policies and initiatives to tackle problems related to loss of biodiversity, inefficient use of resources and poor waste management. It is widely recognised that the EU should work together to tackle the energy challenge. At the same time, the EU has a two-fold approach to the external dimensions of resource challenges. Firstly, the EU has made sustainable development a fully-fledged component of its own narrative worldwide. Secondly, as do all actors, it has an interest in protecting its self-interests amidst increasing global competition over resources. However, in order to tackle the resource challenge effectively, the EU must both turn words into action within Europe and clarify its external strategy and the means to implement it

In this work, a facile hydrothermal route has been proposed for the morphology-controllable preparation of Eu-doped yttrium orthovanadate (YVO 4 :Eu 3+ ) powders in the presence of sodium dodecyl sulfonate (SDS) as a template in a wide pH range. The structure, composition, morphology, and optical properties of the final products were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and photoluminescence spectroscopy (PL), respectively. It was found that single phase YVO 4 :Eu 3+ micro- and nanocrystals with different shapes can be fabricated at 180 deg. C for 24 h with suitable amount of SDS in a wide pH range. The formation mechanism and the influence of SDS on the morphology of YVO 4 :Eu 3+ micro- and nanocrystals were investigated as a function of pH value. The PL measurement revealed that the samples with different morphologies exhibited different values for optical properties, especially soybean-like nanopowders showed a higher intensity compared to other samples with different morphologies due mainly to their high packing densities and low scattering of light.

Blue-emitting BaMgAl10O17:Eu2+ (BAM:Eu), suitable for applications in a next generation of Hg-free lamps based on UV LEDs, was prepared by a microwave induced solution combustion synthesis, using urea as combustion fuel and nitrates as oxidizers. Purity control of the as-synthesized blue phosphor was undertaken by a washing step followed by a reduction one. Structural and morphological properties of the outcoming phosphors have been considered. Synthesis process allows producing a well-crystallized and nanostructured BAM phase within only few minutes. The influence of reduction treatment on the relative amounts of Eu2+/Eu3+ in our samples has been investigated through an original study by magnetization and Mössbauer spectroscopy. Furthermore, a complete optical study has been carried out and allowed us to determine the europium localization in the three possible sites in BAM matrix. The percentage of Eu2+ increased twofold after the reduction treatment, entailing an increase in the luminescence efficiency upon UV excitation. Finally, temperature-dependent luminescence of combustion-derived powders has been studied till 170 °C and compared to that of commercial BAM:Eu. MISCS-derived phosphors present a higher thermal stability than commercial one: whereas the emission efficiency of this last was reduced by 64%, the one of combustion-derived BAM:Eu experienced an only 12% decline. Furthermore, while commercial BAM suffered from a severe blue-shift with increasing temperature, our phosphors keep its color quality with a good stability of the photometric parameters.

The EU promotes a culture of CBRN safety and security within the EU and internationally. Accordingly, the Instrument Contributing to Stability and Peace (IcSP) contributes to international efforts to mitigate CBRN risks, whether of natural (e.g. pandemics, volcanic eruptions), accidental (Fukushima) or criminal (trafficking, terrorism) origin, following a consistent ‘all hazards’ approach. The aim is twofold: to prevent CBRN incidents and to build partner countries' capacities for emergency r...

As a result of a lawsuit initiated by Washington activist Jeremy Rifkin and joined by the attorney general for the state of Utah, the U.S. Army has agreed to defer construction, pending a study of potential environmental hazards, of a new laboratory that was authorized by a small number of Congressmen under an unusual procedure in December 1984. The laboratory, intended for tests of highly infectious and lethal biological aerosols, has aroused controversy because of fears that the data gathered there might be used to develop offensive biological weapons.

Full Text Available In despite of extensive research of franchising in the scientific community, there are a lot of unresolved issues relating to franchising, in particular its regulation at the national level and at the level of the European Union that is why the purpose of the paper is to summarise and present the difference between state regulation of franchising in the EU member states and to research the basic principles of state regulation of franchising in the EU also to analyze legislation of the franchise relationship. Methodology. The survey is based on a comparison of data from all EU member countries and analisis of the legal framework of each country in particular and in general EU legislation. The article is devoted to a detailed analysis of main features of the franchise business in Europe. The mechanism of implementation of franchise relations between EU member states are studied. Government regulation of franchising in the EU member states are investigated. The rate of growth of franchising in Europe are analized. Results. By comparing different state laws and regulations of franchising we have identified the most effective and productive. We divided counties into two groups due to their regulation of franchising: countries which do not have a special government regulation of franchising; the countries which have state regulation of franchising; countries which have government regulation of franchising and it is governed by EU law, countries in which regulation is carried out in accordance with EU law. Thus, results of the survey showed that government regulation of franchising, as well as its regulation at the level of EU institutions have a positive impact on the development of franchising relationships. Practical implications of the results of the paper will help to develop well known network of franchise bussiness without legislative interference. Value/originality. It is first time we have grouped countries due to the main aspects of state

Eu-emission quenching by electron screening in VO2 thin films

As a kind of phase transition functional material, Vanadium dioxide (VO 2 ) thin films deposited on fused quartz substrate were fabricated using pulsed laser deposition (PLD) technique. Europium was introduced for structure study. By laser excitation at 526 nm, VO 2 thin film undergoes a reversible and ultrafast phase transition from semiconductor to metallic state, which results in a change of optical properties. In fluorescence measurement, Eu emission was found severely quenched in all as-grown thin films. After annealing the sample in air, a red Eu-emission appeared. The emission spectrum is characterized by a pronounced twin peak, centered at 617 nm ( 5 D - 7 F 2 ), surrounded by a set of broad, but relatively weaker bands (emission from 5 D to 7 F j manifold). The emission lifetime increased when the sample annealed at higher temperature for longer time. Each spectral component is actually a doublet which is the spectral overlap of emissions from Eu 3+ situated in two sites with different configurations. One is a linear h-Eu 3+ -h, where h stands for holes. Another is a right-angle configuration of h-Eu 3+ -h with Eu 3+ in the corner. In as-grown VO 2 film, Eu 3+ ions can either substitute V 4+ , leaving a negative charge around (Eu 3+ -O) - , or substitute V 5+ , leaving two negative charges around (Eu 3+ -O) -- . Due to trapped electrons in a large radius state, it covers Eu 3+ V 4+ -V 5+ complexes. It suggests that the screening by degenerate electronic gas may result in switching off the Eu-related optical response for a wide spectral region, causing emission quenching in VO 2 films

A spectroscopic investigation of zinc phosphate glasses activated with Eu{sup 3+}, Tb{sup 3+}/Eu{sup 3+} and Ce{sup 3+}/Tb{sup 3+}/Eu{sup 3+} ions is performed through photoluminescence spectra and decay time measurements. Greenish-yellow light emission, with x=0.42 and y=0.50 CIE1931 chromaticity coordinates, is obtained in the 5.0% Tb(PO{sub 3}){sub 3}-2.0% Eu(PO{sub 3}){sub 3} codoped zinc phosphate glass upon Tb{sup 3+} excitation at 340 nm. Such greenish-yellow luminescence is generated mainly by the {sup 5}D{sub 4}{yields}{sup 7}F{sub 6,5} and {sup 5}D{sub 0}{yields}{sup 7}F{sub 1,2} emissions of Tb{sup 3+} and Eu{sup 3+}, respectively, europium being sensitized by terbium through a non-radiative energy transfer. By codoping with 0.1 Ce(PO{sub 3}){sub 3} in addition to Tb{sup 3+}/Eu{sup 3+} yellowish-green light emission with CIE1931 chromaticity coordinates, x=0.33 and y=0.48, is achieved through non-radiative energy transfer from Ce{sup 3+} to Tb{sup 3+} and from Ce{sup 3+} via Tb{sup 3+} to Eu{sup 3+} upon 280 nm excitation (peak emission wavelength of AlGaN-based LEDs). - Highlights: Black-Right-Pointing-Pointer Zn(PO{sub 3}){sub 2} glasses are optically activated with Tb{sup 3+}/Eu{sup 3+} (ZPO5Tb2Eu) and Ce{sup 3+}/Eu{sup 3+}/Tb{sup 3+} (ZPOCe5Tb2Eu). Black-Right-Pointing-Pointer Non-radiative energy transfer Tb{sup 3+}{yields}Eu{sup 3+} takes place in ZPO5Tb2Eu. Black-Right-Pointing-Pointer Greenish-yellow light is generated by ZPO5Tb2Eu pumped with 340 nm-UV light. Black-Right-Pointing-Pointer Non-radiative energy transfer Ce{sup 3+}{yields}Tb{sup 3+} and Ce{sup 3+}{yields}Eu{sup 3+} via Tb{sup 3+} takes place in ZPOCe5Tb2Eu. Black-Right-Pointing-Pointer Yellowish-green light is generated by ZPOCe5Tb2Eu pumped with 280 nm-UV light (AlGaN-LEDs).
