    Full Text Available Since the terrorist attacks in New York and Washington, DC (2001, Madrid (2004 and London (2005, the European Union (EU has stepped up its efforts to develop new instruments and reinforce existing ones to fight terrorism jointly. One of the key aspects of the EU-wide fight against terrorism and serious crime is the facilitation and enforcement of information and intelligence exchange among law enforcement authorities and, to a limited extent, security and intelligence services. This article examines how far the EU’s commitment to democracy, accountability and transparency is actually fulfilled with respect to its efforts at fighting terrorism by drawing on the example of the activities of the European Police Office (Europol. Taking the European Parliament (EP and National Parliaments (NPs, but also inter-parliamentary forums, into account, the article analyses how, and to what extent, mechanisms of democratic accountability and, in particular, parliamentary scrutiny are in place to hold EU-wide counter-terrorism actors, such as Europol, to account. This is a particularly timely question given that Europol’s parliamentary scrutiny procedures are currently subject to considerable changes due to the change in its legal mandate as of 1 January 2010 and the entry into force of the Lisbon Treaty.

    In political science literature, federal systems may be classified as ‘dual’ or ‘co-operative’ polities. This contribution further explores this dichotomy between dual and co-operative systems from the perspective of Spain and Belgium, two EU member states that may be qualified as ‘dual’ systems.

    Full Text Available The EU’s international agreements with Morocco on trade in agricultural and fishery products have drawn criticism due to their application to the disputed territory of Western Sahara, a territory that remains on the list of non-self-governing territories to be decolonised in accordance with the right of self-determination of the indigenous Sahrawi people. Recently, the Sahrawi liberation movement Front Polisario brought an action for annulment before the General Court of the European Union (GC against the Council Decision approving the conclusion of one such agreement, alleging multiple violations of European and international legal norms. Interestingly, although the GC concurred by annulling the Decision insofar as it applies to Western Sahara, it chose to exclusively base its judgment on EU fundamental rights, invoking the EU’s failure to ensure that the fundamental rights of the Sahrawi people were not infringed by applying the agreements to Western Sahara. By summarily setting aside Front Polisario’s other claims, several relevant questions of applicable international and European law, which warrant further discussion, remain. This article examines these questions using the GC’s judgment in Front Polisario, thereby combining general matters of international and European law with the specific circumstances of the EU-Morocco relations and Western Sahara.

  8. 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)

    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

    Theranostic nanoparticles currently have been regarded as an emerging concept of ‘personalized medicine’ with diagnostic and therapeutic dual-functions. Eu 3+ doped hydroxyapatite (HAp) has been regarded as a promising fluorescent probe for in vivo imaging applications. Additionally, substitution of Ca 2+ with Fe 3+ in HAp crystal may endow the capability of producing heat upon exposure to a magnetic field. Here we report a preliminary study of doping mechanism and photoluminescence of Eu 3+ and Fe 3+ doped HAp nanoparticles (Eu/Fe:HAp). HAp with varied concentration of Eu 3+ and Fe 3+ doping are presented as Eu(10 mol%):HAp, Eu(7 mol%)-Fe(3 mol%):HAp, Eu(5 mol%)-Fe(5 mol%):HAp, Eu(3 mol%)-Fe(7 mol%):HAp, and Fe(10 mol%):HAp in the study. The results showed that the HAp particles, in nano-size with rod-like morphology, were successfully doped with Eu 3+ and Fe 3+ , and the particles can be well suspended in cell culture medium. Photoluminescence analysis revealed that particles have prominent emissions at 536 nm, 590 nm, 615 nm, 650 nm and 695 nm upon excitation at a wavelength of 397 nm. Moreover, these Eu/Fe:HAp nanoparticles belonged to B-type carbonated HAp, which has been considered an effective biodegradable and biocompatible drug/gene carrier in biological applications.

    The phenomenon of stimulable luminescence of phosphors pre-irradiated with high-energy radiation is widely used in the field of imaging. Phosphors such as BaFX:Eu (X = Cl, Br) are extensively used in x-ray screens for digital image processing. There is, however, divided opinion regarding the mechanism responsible for the luminescence process in these materials. In this paper we have discussed the role of Eu sup 3 sup +reversible Eu sup 2 sup + conversion in BaFCl:Eu phosphor using PL, TL, TL emission and ESR techniques. (author)

    The theoretical investigation on the mechanical, dynamical and electronic properties of MgEu in CsCl-type structure has been carried out through the ab-initio calculations within the framework of the density functional theory and the density functional perturbation theory. For the purpose, Vienna Ab initio Simulation Package and Phonopy packages were used. Our calculated ground-state properties of MgEu are in good agreement with other available results. Our computed elastic constants and phonon spectrum results suggest that MgEu is mechanically and dynamically stable up to 5 GPa. The thermodynamic quantities as a function of temperatures are also reported and discussed. The band structure, density of states and charge density also calculated to understand the electronic properties of MgEu.

    The clinic is a loaded space for LGBTQI persons. Historically a site of pathology and culturally a site of stigma, the contemporary clinic for queer patient populations and their loved ones is an ethically fraught space. This paper, which introduces the featured articles of this special issue of the Journal of Bioethical Inquiry on "Bioethics, Sexuality, and Gender Identity," begins by offering an analysis of scrutiny itself. How do we scrutinize? When is it apt for us to scrutinize? And what are the benefits and perils of clinical and bioethical scrutiny? Bearing in mind these questions, the second half of this paper introduces the feature articles in this special issue in response to such forms of scrutiny. How, why, when, and in what ways to sensitively scrutinize LGBTQI persons in the clinic are the aims of this piece.

  19. Optical properties, luminescence quenching mechanism and radiation hardness of Eu-doped GaN red powder phosphor

    We report on the luminescence quenching mechanism of Eu-doped GaN powder phosphor produced with a low-cost, high yield rapid-ammonothermal method. We have studied as-synthesized and acid rinsed Eu-doped GaN powders with the Eu concentration of ∼0.5 at.%. The Eu-doped GaN photoluminescence (PL) was investigated with 325 nm excitation wavelength at hydrostatic pressures up to 7.7 GPa in temperature range between 12 K and 300 K. The room temperature integrated Eu 3+ ion PL intensity from acid rinsed material is a few times stronger than from the as-synthesized material. The temperature dependent PL studies revealed that the thermal quenching of the dominant Eu 3+ ion transition ( 5 D 0 → 7 F 2 ) at 622 nm is stronger in the chemically modified phosphor indicating more efficient coupling between the Eu 3+ ion and passivated GaN powder grains. Furthermore, it was found that thermal quenching of Eu 3+ ion emission intensity can be completely suppressed in studied materials by applied pressure. This is due to stronger localization of bound exciton on Eu 3+ ion trap induced by hydrostatic pressure. Furthermore, the effect of 2 MeV oxygen irradiation on the PL properties has been investigated for highly efficient Eu-doped GaN phosphor embedded in KBr-GaN:Eu 3+ composite. Fairly good radiation damage resistance was obtained for 1.7 x 10 12 to 5 x 10 13 cm -2 oxygen fluence. Preliminary data indicate that Eu-doped GaN powder phosphor can be considered for devices in a radiation environment.

  20. Fossil fuel subsidies and the new EU Climate and Energy Governance Mechanism

    International Nuclear Information System (INIS)

    Sartor, Oliver; Spencer, Thomas

    2016-07-01

    There is currently no dedicated process to track the extent of fossil fuel subsidies, nor to ensure that Member States phase them out. This situation is inconsistent with the European Union's stated decarbonization and energy efficiency dimensions under the Energy Union. The EU is therefore in need of an alternative process for tracking and ensuring the phase-out of fossil fuel subsidies by the Member States. The new Energy Union governance mechanism presents an opportunity for creating this alternative. Providing the right price signals is essential part of the policy mix that is needed to achieve Europe's climate policy goals. Phasing out fossil fuel subsidies in the EU is an important part of aligning energy prices with the EU's climate and energy goals. Depending on how they are measured, combined fossil fuel subsidies in the EU range from 39 to over euro 200 billion per annum (European Commission, 2014). They therefore constitute a significant source of incoherence between the EU's climate mitigation and fiscal policies for energy. However, there has recently been mixed progress in addressing fossil fuel subsidies in Europe. For instance, under the Europe 2020 Strategy, Member States had committed to begin developing plans for phasing out fossil fuel subsidies by 2020. Progress on implementing these plans was supposed to be monitored under the European Semester. However, the decision was taken to remove the focus on energy and fossil fuel subsidies from the European Semester in 2015. As yet, no new system for governing the phase-out of fossil fuel subsidies has been advanced, leaving the question of fossil fuel subsidy reform in limbo. The advent of the EU's Energy Union project creates an opportunity for putting the phase-out of fossil fuel subsidies back on track in Europe. This could be done by including requirements for national goal setting on specific kinds of fossil fuel subsidies in a dedicated sub-section of the National Climate and Energy Plans

  1. Charge compensation mechanisms in favor of the incorporation of the Eu3+ ion into the ZnO host lattice

    Eu3+ doped phosphors with charge compensation are potential candidates of red emitting phosphors for lamp applications. Charge compensation improves the luminescence performance of the material. The charge compensation can most probably be achieved by three possible mechanisms: (a) two Zn2+ ions are replaced by one Eu3+ ions and one monovalent cation, 2Zn2+ →Eu3++ Li+, where Li+ is acting as a charge compensator; (b) the charge compensation is provided by a zinc vacancy (VZn) defects, 3Zn2+ → 2Eu3++ VZn, the subscript Zn denotes an ion in a normal zinc site in the lattice; (c) two Zn2+ ions are replaced by one Eu3+ ions with the presence of interstitial oxygen (Oi), 2Zn2+ → 2Eu3++ Oi. Electronic structures of the crystals corresponding to the three models are evaluated by the first-principles quantum mechanical calculations based on the density functional theory. It is found that the charge compensator defects make Eu3+ doping in ZnO energetically more favorable. They break the local symmetry around the Eu3+ ion and lead to deep states below the empty upper band, the conduction band that could facilitate intra-4f shell transitions, which can obviously improve the emission intensity of Eu3+-doped ZnO. Therefore, the effect of these defects on the host crystals electronic band states relative to the Eu3+ states is reported, since both electron transfer and electronically energy transfer processes enhance the performance of optoelectronic devices based on this material. These theoretical insights are helpful for designing rare-earth doped oxide materials with high photoluminescence (PL) performance.

  2. Reducing Greenhouse Gas Emissions in India. Financial mechanisms and opportunities for EU-India collaboration

    This report illuminates potential areas for collaboration between the EU and India on actions that reduce greenhouse gas emissions in India. If human-induced climate change is to have any hope of being limited to 2 degrees, it is essential that ways are found to address rapidly rising greenhouse gas emissions in India, as elsewhere. This is a challenging proposition: even though India's per capita emissions are very low, her 1.15 billion people are collectively a major source of greenhouse gas emissions. This fact, coupled with the immediate task of tackling widespread poverty, means that the international community must play a major role in providing financial and technological resources to support India's domestic efforts. As India's 2008 National Action Plan on Climate Change recognises, tackling the country's greenhouse gas emissions means not least finding ways to transform a rapidly growing energy sector. International financial mechanisms such as the Clean Development Mechanism and the Global Environment Facility have been unable to deliver the scale of transformative change needed to shift India's emissions trajectory. While the Indian government has already initiated some ambitious policy measures - particularly pertaining to solar energy and energy efficiency- the effectiveness of international finance mechanisms and other forms of international partnership will be crucial in determining the success of greenhouse gas mitigation efforts. The EU India Summit is held a month before COP15 negotiations in Copenhagen. While this provides challenges in terms of seeking concrete agreements on questions of finance, it is also an important opportunity to devise complementary efforts outside the UNFCCC process. Genuine, productive collaboration could not only be used to foster the sorts of transformative changes that are needed in India's growing economy but could also create a spirit of cooperation that spills over into UNFCCC

  3. Free allocation in the European Emissions Trading System (EU ETS): identifying efficient mechanisms through to 2030

    International Nuclear Information System (INIS)

    Jalard, Matthieu; Alberola, Emilie

    2015-11-01

    In a world with asymmetrical climate policies, the conclusions of the European Council of October 2014 agreed on continuing the allocation of free CO 2 emissions allowances beyond 2020 to industrial sectors in the EU ETS. This statement has been confirmed in the European Commission's proposal to revise EU ETS directive for phase IV disclosed in July 2015. The stated objective is to ensure that the most efficient industrial installations do not face undue carbon costs which would lead to carbon leakages. Furthermore, free allocations should not undermine the incentive to cut CO 2 emissions, lead to distortions or windfall profits and reduce the auctioning share of allowances. From 2013 to 2020, the allocation of free allowances has been defined according to harmonized European rules based on benchmarks (carbon intensity targets) and historical output adjusted to the free allocation cap by applying the Cross-Sectoral Correction Factor (CSCF). What would be the impact of pursuing the current mechanism through to 2030? Does the EU Commissions' proposal of 15 July respond to the Council's requirements? Which alternative mechanisms could do so? This study examines four scenarios and their potential consequences. - Scenario 1 continues the current free allocation mechanism until 2030. The volume of free allocations thus calculated would be higher than the available free allocation cap and would need to be reduced by a Cross-Sectoral Correction Factor (CSCF) of 66% in 2030. Carbon costs would thus increase for all installations, regardless their exposure to carbon leakages, reducing the protection of most exposed sectors, while widely allocating sectors with limited exposure. - Scenario 2 analyses the proposal to implement an allocation mechanism based on recent industrial output combined with appropriate updating of benchmarks. This allocation method is more effective in combating carbon leakage, as it gives clearer incentive to maintain domestic production

  4. Understanding the differing governance of EU emissions trading and renewable: feedback mechanisms and policy entrepreneurs

    Energy Technology Data Exchange (ETDEWEB)

    Boasson, Elin Lerum; Wettestad, Joergen

    2010-04-15

    This paper presents a comparative study of two central EU climate policies: the revised Emissions Trading System (ETS), and the revised Renewable Energy Directive (RES). Both were originally developed in the early 2000s and revised policies were adopted in December 2008. While the ETS from 2013 on will have a quite centralized and market-streamlined design, the revised RES stands forward as a more decentralized and technology-focused policy. Differing institutional feed-back mechanisms and related roles of policy entrepreneurs can shed considerable light on these policy differences. Due to member states' cautiousness and contrary to the preferences of the Commission, the initial ETS was designed as a rather decentralized and 'politicized' market system, creating a malfunctioning institutional dynamic. In the revision process, the Commission skillfully highlighted this ineffective dynamic to win support for a much more centralized and market-streamlined approach. In the case of RES, national technology-specific support schemes and the strong links between the renewable industry and member states promoted the converse outcome: decentralization and technology development. Members of the European Parliament utilized these mechanisms through policy networking, while the Commission successfully used developments within the global climate regime to induce some degree of centralization.

    The proliferation of EU agencies, referred to as agencification phenomenon, constitutes a significant EU institutional innovation. Agencification aimed to provide information, promote efficiency, decrease politicization and generate standards based on specialised technical knowledge. However...... this article claims that in order to assess the overall legitimacy of the EU regulatory governance through agencies, the ‘throughput’ criterion needs to be considered. Although important, the ‘input’ (politics) and ‘output’ (policy) criteria fail to capture what happens within the actual governance (process...

    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.

  7. Capacity mechanisms and cross-border participation: the EU wide approach in question

    International Nuclear Information System (INIS)

    Finon, Dominique

    2014-07-01

    A capacity remuneration mechanism (CRM) which excludes cross border participants is considered to have serious distortive effects on long term competition, compared to explicit cross border participation (CBP), on the grounds that it doesn't capture the advantages of multi-system competition. This paper examines the reality of these advantages by distinguishing situations with and without congestion between systems during critical periods because congestion separates markets and their collective goods of reliability and adequacy for each system, and suppresses any economic and physical relevance of a capacity commitment from a new external participant to a CRM. From the limited perspective of any single system, there are two potential advantages of explicit CBP: the first is the supplement of the set of committed capacities to a CRM; the second is the lower cost of the adequacy policy of the system, thanks to enlarged competition, but it is illusory because the clearing price of capacity is the same with and without explicit CBP. Moreover concretization of such benefits for the system is not possible when there is congestion. From the EU wide perspective, we identify some potential gains of social efficiency from explicit CBP at the multi-system level, when we have systems with a long standing situation of over-capacity beside systems with tight situations during their critical periods; or when there exists projects of hydro equipment (pumping storage, etc... But again, congestion removes any sense to any additional revenue to them. In any case erratic revenues certainly do not steer new investment towards either system. Furthermore exchanges of capacity rights between systems equipped with different CRMs introduce a supplement of distortions compared to the same situation with implicit CPB and no trade of capacity rights. It is problematic in the case of congestion; this delays the price signal of capacity scarcity in the system with the least attractive CRM in

    We investigated the Li{sup +} ion incorporation in Ba{sub 2}GdNbO{sub 6}:Eu{sup 3+} perovskite by atomistic simulations based on energy minimization. We predicted the most probable sites occupied by Eu{sup 3+} and Li{sup +} ions and the related charge-compensation mechanisms involved into these substitutions. The results show that the Eu{sup 3+} and Li{sup +} ions are incorporated mainly at the Gd{sup 3+} site. In the Li{sup +} ion case, there is a charge compensation by Nb{sub Gd}{sup •} {sup •} antisite. The crystal field parameters and the transition levels for the Eu{sup 3+} ion in the BGN:Eu{sup 3+} were calculated with basis on the simulated local symmetry of the Eu{sup 3+} site. The results show that the mechanism of luminescent properties enhancement is the symmetry distortion induced by the Li{sup +} co-doping. - Highlights: • We performed a full defect calculations in Ba{sub 2}GdNbO{sub 6} double perovskite. • We modeled with excellent agreement the optical transition of Ba{sub 2}GdNbO{sub 6}:Eu{sup 3+} crystal. • We explained the mechanism of luminescent enhancement in Ba{sub 2}GdNbO{sub 6}:Eu{sup 3+} perovskite by Li{sup +} co-doping.

    We examine whether people are more honest in public than in private. In a laboratory experiment, we have subjects roll dice and report outcomes either in public or in private. Higher reports yield more money and lies cannot be detected. We also elicit subjects' ethical mindsets and their expectations about others' reports. We find that outcome-minded subjects lie less in public to conform with their expectations about others' reports. Ironically, these expectations are false. Rule-minded subjects, in turn, do not respond to public scrutiny. These findings challenge the common faith in public scrutiny to promote ethical behavior. While public scrutiny eventually increases honesty, this effect is contingent on people's mindsets and expectations.

  15. U(VI) and Eu(III) ion sorption in the interface solution-phosphate solids: Structural study and mechanisms

    Drot, Romuald

    1998-01-01

    As part of the storage of nuclear wastes in a deep underground disposal, radionuclides sorption on geological or engineered barriers is one of the most important factor which could enhance retardation. Thus, the knowledge of such mechanisms is needed. For this purpose, we chose to experimentally define sorption equilibria before performing simulation of retention data. Several phosphate compounds are potential candidates as engineered barrier additives. We considered Th 4 (PO 4 ) 4 P 2 O 7 , Zr 2 O(PO 4 ) 2 which allow to study the effect of PO 4 and P 2 O 7 groups separately. Eu(III) and U(IV) ions were used as structural probes in order to simulate actinides (III) and (VI) behavior. X-ray powder diffraction, IR spectroscopy and electron probe microanalysis were used to characterized the synthesized solids. Electrophoretic measurements showed an amphoteric behavior of surface sites. Moreover, laser spectro-fluorimetry experiments indicated that no diffusion phenomena of the sorbed ion inside the solid occurs. Thus, we considered that a surface complexation model should be applied. Laser spectro-fluorimetry and XPS allowed to determine the nature of surface sites. ZrP 2 O 7 presents only one single site (P 2 O 7 groups) whereas Th 4 (PO 4 ) 4 P 2 O 7 and Zr 2 O(PO 4 ) 2 admit two types of sites (PO 4 /P 2 O 7 and PO 4 /oxo groups, respectively). Sorbed species were identified using laser spectro-fluorimetry which indicate that, in KNO 3 0.5 M medium and for a known surface site, there are two surface complexes for U(VI) (sorption of UO 2+ 2 et de UO 2 NO + 3 species) and only one for Eu(III) (sorption of EuNO 2+ 3 ). They are linked to the substrate as bidentate inner sphere complexes (EXAFS study). Surface acidity constants were determined by simulation of potentiometric titration curves obtained for each solid suspension using FITEQL code (CCM). As sorption equilibria were defined, experimental retention data simulation was performed with respect to structural

  16. Cooperation mechanisms of the EU renewable energy directive and flexible mechanisms of the Kyoto Protocol: comparison and lessons learnt. Working paper

    Frieden, Dorian; Tuerk, Andreas; Steiner, Daniel

    2013-07-15

    This working paper discusses similarities and differences between the cooperation mechanisms of the EU renewable energy directive (RES directive) and the flexible mechanisms of the Kyoto Protocol. The cooperation mechanisms allow the (virtual) trade of renewable energy and were introduced with the RES directive to provide Member States (MS) with greater flexibility to achieve their national targets for renewable energy sources (RES). A similar kind of flexibility is known from the flexible mechanisms of the Kyoto Protocol which aim at the cost efficient achievement of emission reduction targets. Lessons learned from the Kyoto mechanisms may allow conclusions to be drawn on the design and implementation of the renewable energy cooperation mechanisms. This paper first gives an overview of the cooperation mechanisms regarding their potential, advantages and disadvantages, barriers and preconditions. This is followed by a brief explanation of and a systematic comparison with the flexible mechanisms of the Kyoto Protocol – Joint Implementation (JI); Clean Development Mechanism (CDM); and International Emissions Trading (IET). A gamut of factors influenced the success of the Kyoto mechanisms in general and in specific national contexts. Therefore, it is not possible to directly transfer past experiences with the Kyoto mechanisms to the capability of specific nations to make use of the renewable energy cooperation mechanisms. A comparison of specific features, such as the mechanism type (transfer, project-based, support scheme), price building and specific barriers can, however, help anticipate the possible dynamics and challenges of the cooperation mechanisms. Experiences with the Kyoto mechanisms show that predictions based on supply-demand analysis were valid only to a limited extent and that specific factors such as institutional capacity constraints or legal uncertainties delayed or prevented the use of the mechanisms in some cases. Similarly, for the cooperation

    2016-01-01

    Full Text Available In order to completely understand and analyse the transmission mechanism, it is necessary to observe all factors conditioning its overall efficiency as well as the efficiency of individual transmission channels. This paper focuses on countries that have successfully passed the transition period and have experience with implementing different monetary policy regimes. The evolution of monetary policy resulted in the development of instruments through which central banks influence the real sector activity by means of a transmission mechanism. The empirical analysis based on econometric tools investigates the efficiency of transmission mechanism channels, or more precisely, their significance in the monetary targeting regime. With a view to reaching the conclusion about the direction in which it is necessary to develop the structure of the real and financial sector, aimed at a better functioning of monetary policy instruments, the paper features a theoretical analysis of the characteristics of the monetary policy in the developed economies, as well as the structural characteristics of these economies.

    Full Text Available The article gives a definition to the concept of ‘deep integration’ taken by the Ukrainian Government as a framework concept for the establishment of a Ukraine-EU free trade area. The paper uses the term ‘deep free trade’ or ‘free trade area +’. It offers a review of the Ukrainian economy and its readiness to open such industries as mechanical engineering, chemical and light industry to free trade with the EU. It examines which cooperative steps might be taken in the sectors in question in the framework of a free trade area by identifying specific features of those sectors in Ukraine and the EU through SWOT analysis and review of certain provisions in relevant agreements between the EU and other countries. It proposes to forecast the possible impact of a free trade area on stakeholders’ position regarding the agreement by using the ‘stakeholder approach’ (identifying and classifying interest groups and the European Commission’s method of ‘impact assessment’. Based on the results of this research, conclusions are made concerning the fundamental negotiation principles for talks between Ukraine and the EU as to the economic and trade component of the new ‘enhanced agreement.

    2017-10-01

    Full Text Available Both the EU and China face a number of challenges. The EU has reached the pinnacle of international identity and is going through a rather difficult process of rethinking it. Regarding China, this actor goes through a phase of rethinking its economic growth model, namely the transition from an economy based, in greater extent on exports and investment to an economic growth based on stimulating domestic consumption. In this context, in order to meet the challenges of the third millennium and beyond, the two actors need to strengthen their cooperative relations as they are vital in solving the challenges of this millennium. This paper aims to provide an overview of EU-China economic relations and to analyse the impact of these relations on the EU economy.

    The N2HDM is based on the CP-conserving 2HDM extended by a real scalar singlet field. Its enlarged parameter space and its fewer symmetry conditions as compared to supersymmetric models allow for an interesting phenomenology compatible with current experimental constraints, while adding to the 2HDM sector the possibility of Higgs-to-Higgs decays with three different Higgs bosons. In this paper the N2HDM is subjected to detailed scrutiny. Regarding the theoretical constraints we implement tests of tree-level perturbativity and vacuum stability. Moreover, we present, for the first time, a thorough analysis of the global minimum of the N2HDM. The model and the theoretical constraints have been implemented in ScannerS, and we provide N2HDECAY, a code based on HDECAY, for the computation of the N2HDM branching ratios and total widths including the state-of-the-art higher order QCD corrections and off-shell decays. We then perform an extensive parameter scan in the N2HDM parameter space, with all theoretical and experimental constraints applied, and analyse its allowed regions. We find that large singlet admixtures are still compatible with the Higgs data and investigate which observables will allow to restrict the singlet nature most effectively in the next runs of the LHC. Similarly to the 2HDM, the N2HDM exhibits a wrong-sign parameter regime, which will be constrained by future Higgs precision measurements.

    Full Text Available In the area of computer security the problem of polyinstantiation is widely recognized. The research on polyinstantiation can be considered morally questionable, since it involves lying. This being the case, a moral scrutiny on the problem of polyinstantiation is warranted. The morality of polyinstantiation shall be critically analysed from the viewpoint of a moral philosophical framework. The moral philosophical framework used includes 1 Kantian ethics, 2 the universality theses advocated by Hare, Rawls, Gewirth, Jewish-Christian ethics, and Confucian ethics, 3 utilitarianism, and 4 Theory of Information Ethics (IE by Floridi. The result of this analysis suggests that research and practice on polyinstantiation is morally questionable, at least in the light of the chosen moral philosophical theories. The aim of the paper is not, however, to deem polyinstantiation as morally wrong altogether, but to provide researchers and practitioners with tools and insights for analyzing the morality of polyinstantiation in different cases. Moreover, the results suggest that, as far as polyinstantiation is concerned, traditional ethics theories seem to be at least as adequate as IE.

    2010-01-01

    Under European Union proposals for CO 2 emission reduction between 2013 and 2020, a Member State can transfer to another Member State the right to use its unused Clean Development Mechanism ('CDM') credits. The paper addresses three issues in relation to these CDM Warrants ('CDM W '). First, how should the Member State treat the CDM W in making decisions concerning emission reduction? The price of the property right is an important signal for a Member State in deciding the level of domestic abatement compared to trading in CDM W s. In other words, a shadow price for CDM W s should be used in formulating the emission strategy in order to determine whether or not a Member State is a buyer or seller of CDM W s. Second, what mechanism should be used to facilitate the exchange of CDM W s? The preferred mechanism depends on the market size, over which there appears to be some ambiguity: market intermediaries such as Over-the-Counter trades and exchanges are preferred if market size is small; auctions if the market size is large. Third, who should realise the value of CDM W s-the State, existing polluters, etc.? The value of CDM W s should accrue to the State. - Research highlights: →Clean Development Mechanism Warrants (CDMw) reduce the costs of emission reduction. →Member States should explicitly take into account the value of the CDM w s. →Appropriate market mechanisms - exchanges or auctions - should be created. →The value of CDM w s should accrue to government.

    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.

  7. Capacity mechanisms: EU or National Issue? Are capacity remuneration mechanisms helping to build the market or just a symptom of what does not work?

    International Nuclear Information System (INIS)

    Parmigiani, Laura

    2012-10-01

    In a competitive energy system, generation investment choices are let to investors. It is then the responsibility of the market actors to invest and ensure peak, medium and base load generation, based on market perspectives and trends. If through actors' investments the stability of the system cannot be ensured (because, for example, peak generation is not sufficient to satisfy demand), some measures have to be taken. These can have economic and system integrity impacts on neighboring systems, especially if they are connected. This is precisely what is happening in the European electricity market. While the internal electricity market should be completed by 2014, the adoption by Member States of capacity remuneration mechanisms in an uncoordinated way may lead to new market distortions. Whereas national capacity remuneration mechanisms (CRMs) already exist in several European countries (e.g. Italy, Spain, Sweden), others have taken steps in the past months to implement CRMs (France, UK) or contemplated to introduce them (Germany). After the puzzle of more than 27 different regimes for incentivizing renewables, the same heterogeneity will appear in the capacity markets if no coherent and Europe-wide framework is proposed. While increased interconnections and market coupling will lead to more efficient and liquid markets at regional and EU levels, the opposite will happen if Member States adopt national solutions without looking beyond their borders. In order to understand why we have come this point, it is essential to start from the roots of the problem and to throw light on some false beliefs. It would be much easier to blame market liberalization and un-bundling or RES integration into the market. The truth is that both measures were important. Timing showed that the RES production is developing very fast and creates local over capacity in some national systems, while when there is no wind or sun, the conventional plants are still needed to supply the customers

    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.

    The structural, electronic, magnetic and elastic properties of cubic EuMO3 (M  =  Ga, In) perovskites has been successfully predicted within well accepted density functional theory using full potential linearized augmented plane wave (FP-LAPW). The structural study reveals ferromagnetic stability for both the compounds. The Hubbard correlation (GGA+U) calculated spin polarized electronic band and density of states presents half-metallic nature for both the compounds. The magnetic moments calculated with different approximations were found to be approximately 6 µ B for EuGaO3 and approximately 7 µ B for EuInO3. The three independent elastic constants (C 11, C 12, C 44) have been used for the prediction of mechanical properties like Young modulus (Y), Shear modulus (G), Poisson ratio (ν), Anisotropic factor (A) under pressure. The B/G ratio presents the ductile nature for both compounds. The thermodynamic parameters like specific heat capacity, thermal expansion, Grüneisen parameter and Debye temperature etc have also been analyzed in the temperature range 0-900 K and pressure range from 0 to 30 GPa.

    LaCO(3)OH nano/microcrystals with a variety of morphologies/sizes including nanoflakes, microflowers, nano/microrhombuses, two-double microhexagrams sandwichlike microspindles, and peach-nucleus-shaped microcrystals have been synthesized via a facile homogeneous precipitation route under mild conditions. A series of controlled experiments indicate that the pH values in the initial reaction systems, carbon sources, and simple ions (NH(4)(+) and Na(+)) were responsible for the shape determination of the LaCO(3)OH products. A possible formation mechanism for these products with diverse architectures has been presented. After annealing at suitable temperatures, LaCO(3)OH was easily converted to La(2)O(2)CO(3) and La(2)O(3) with the initial morphologies. A systematic study on the photoluminescence and cathodoluminescence properties of Eu(3+)- or Tb(3+)-doped La(2)O(2)CO(3)/La(2)O(3) samples has been performed in detail. The excitation and site-selective emission spectra were recorded to investigate the microstructure, site symmetry, and difference in the (5)D(0) → (7)F(2) transition of Eu(3+) ions in La(2)O(2)CO(3) and La(2)O(3) host lattices. In addition, the dependence of the luminescent intensity on the morphology for the as-prepared La(2)O(2)CO(3)/La(2)O(3):Ln(3+) (Ln = Eu, Tb) samples has been investigated. The ability of generating diverse morphologies and multiemitting colors for different rare-earth activator ion (Ln = Eu, Tb) doped La(2)O(2)CO(3)/La(2)O(3) nano/microstructures provides a great opportunity for the systematic evaluation of morphology-dependent luminescence properties, as well as the full exploration of their application in many types of color display fields.

    Full Text Available This article analyzes the link between culture and diplomacy between Russia and the European Union, and shows the importance of cultural relations. It examines the common space of science, education and culture introduced at the 2003 EU-Russia Summit in St. Petersburg and the application of the principles of this concept that were established at the 2005 EU-Russia Summit in Moscow. It then considers EU-Russia collaboration on humanitarian action and the challenges that both parties face in this sphere. It also explains the formation of EU domestic and foreign cultural policy, and the role of European institutions and states in cultural affairs and diplomacy, as well as key elements and mechanisms of contemporary Russian foreign cultural policy. In addition, the article focuses on the European side of post-Soviet EU-Russia cultural relations. This cultural collaboration is defined as a competitive neighbourhood. EU and Russian interests collide: while Europeans try to promote their values, norms and standards within the framework of the European Neighbourhood Policy, Russia seeks to culturally influence and engage in this region for geostrategic and historical reasons. Finally, the article assesses the prospects for the EU-Russia cultural relations and emphasizes the role of ideology in improving such relations.

    In order to investigate the excitation processes in Eu,O-codoped GaN (GaN:Eu,O), the time-resolved photoluminescence signal including the rising part is analyzed. A rate equation is developed based upon a model for the excitation processes in GaN:Eu to fit the experimental data. The non-radiative recombination rate of the trap state in the GaN host, the energy transfer rate between the Eu3+ ions and the GaN host, the radiative transition probability of Eu3+ ion, as well as the ratio of the number of luminescent sites (OMVPE 4α and OMVPE 4β), are simultaneously determined. It is revealed and quantified that radiative transition probability of the Eu ion is the bottleneck for the enhancement of light output from GaN:Eu. We also evaluate the effect of the growth conditions on the luminescent efficiency of GaN:Eu quantitatively, and find the correlation between emission intensity of GaN:Eu and the fitting parameters introduced in our model.

    Two prototype Nb3Sn cable-in-conduit conductors conductors were designed and manufactured for the toroidal field (TF) magnet system of the envisaged European DEMO fusion reactor. The AC loss, contact resistance and mechanical properties of two sample conductors were tested in the Twente Cryogenic Cable Press under cyclic load up to 30 000 cycles. Though both conductors were designed to operate at 82 kA in a background magnetic field of 13.6 T, they reflect different approaches with respect to the magnet winding pack assembly. The first approach is based on react and wind technology while the second is the more common wind and react technology. Each conductor was tested first for AC loss in virgin condition without handling. The impact of Lorentz load during magnet operation was simulated using the cable press. In the press each conductor specimen was subjected to transverse cyclic load up to 30 000 cycles in liquid helium bath at 4.2 K. Here a summary of results for AC loss, contact resistance, conductor deformation, mechanical heat production and conductor stiffness evolution during cycling of the load is presented. Both conductors showed similar mechanical behaviour but quite different AC loss. In comparison with previously tested ITER TF conductors, both DEMO TF conductors possess very low contact resistance resulting in high coupling loss. At the same time, load cycling has limited impact on properties of DEMO TF conductors in comparison with ITER TF conductors.

  1. Positive mood can increase or decrease message scrutiny: the hedonic contingency view of mood and message processing.

    Wegener, D T; Petty, R E; Smith, S M

    1995-07-01

    Currently dominant explanations of mood effects on persuasive message processing (i.e., cognitive capacity and feelings as information) predict that happy moods lead to less message scrutiny than neutral or sad moods. The hedonic contingency view (D. T. Wegener & R. E. Petty, 1994) predicts that happy moods can sometimes be associated with greater message processing activity because people in a happy mood are more attentive than neutral or sad people to the hedonic consequences of their actions. Consistent with this view, Experiment 1 finds that a happy mood can lead to greater message scrutiny than a neutral mood when the message is not mood threatening. Experiment 2 finds that a happy mood leads to greater message scrutiny than a sad mood when an uplifting message is encountered, but to less message scrutiny when a depressing message is encountered.

    This paper reports the thermoluminescence properties of Eu(3+) doped different host matrix phosphors (SrY2O4 and Y4Al2O9). The phosphor is prepared by high temperature solid state reaction method. The method is suitable for large scale production and fixed concentration of boric acid using as a flux. The prepared samples were characterized by X-ray diffraction technique and the crystallite size calculated by Scherer's formula. The prepared phosphor characterized by Scanning Electron Microscopic (SEM), Fourier Transform Infrared (FTIR), Energy Dispersive X-ray analysis (EDX), thermoluminescence (TL) and Transmission Electron Microscopic (TEM) techniques. The prepared phosphors for different concentration of Eu(3+) ions were examined by TL glow curve for UV, beta and gamma irradiation. The UV 254nm source used for UV irradiation, Sr(90) source was used for beta irradiation and Co(60) source used for gamma irradiation. SrY2O4:Eu(3+)and Y4Al2O9:Eu(3+) phosphors which shows both higher temperature peaks and lower temperature peaks for UV, beta and gamma irradiation. Here UV irradiated sample shows the formation of shallow trap (surface trapping) and the gamma irradiated sample shows the formation of deep trapping. The estimation of trap formation was evaluated by knowledge of trapping parameters. The trapping parameters such as activation energy, order of kinetics and frequency factor were calculated by peak shape method. Here most of the peak shows second order of kinetics. The effect of gamma, beta and UV exposure on TL studies was also examined and it shows linear response with dose which indicate that the samples may be useful for TL dosimetry. Formation of deep trapping mechanism by UV, beta and gamma irradiated Eu(3+) activated SrY2O4 and Y4Al2O9 phosphors is discussed in this paper. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Highlights: ► New long-lasting CdSiO 3 : Mn 2+ , RE 3+ (RE = Tb, Eu, Nd) phosphors were synthesized by a sol–gel method. ► The afterglow performance of the CdSiO 3 : Mn 2+ , Eu 3+ phosphor was the best. ► The role of RE 3+ co-doped into the CdSiO 3 : Mn 2+ matrix was discussed in this paper. -- Abstract: Mn 2+ and RE 3+ (RE = Tb, Eu, Nd) co-doped CdSiO 3 orange phosphors were prepared at 1050 °C by a sol–gel method. The phase and crystallinity of the synthesized materials were investigated by X-ray powder diffraction (XRD) and scanning electron microscopy (SEM). The luminescence characteristics were analyzed using photoluminescence (PL) spectra, afterglow decay curves, long-lasting phosphorescence spectra, and thermoluminescence (TL) spectra. Due to the difference in co-doped rare earth ionic radii, it varied greatly in trap density and trap depth caused by the different defects deriving from RE 3+ ions co-doping into the CdSiO 3 : Mn 2+ host. The afterglow intensity and time for these samples increased as follows: CdSiO 3 : Mn 2+ 0.2%, Nd 3+ 0.8% 3 : Mn 2+ 0.4%, Tb 3+ 0.8% 3 : Mn 2+ 0.4%, Eu 3+ 0.3%. CdSiO 3 : Mn 2+ 0.4%, Eu 3+ 0.3% had the best afterglow properties, which could be due to the proper traps formed by Eu 3+ ions co-doping into the host. The role of RE 3+ co-doped into the CdSiO 3 : Mn 2+ matrix and the possible long-lasting phosphorescence process was also discussed in this paper.

    Nanocrystal rods of Eu{sup 3+}/Tb{sup 3+}-co-doped ZrO{sub 2} were synthesized using a simple chemical precipitation technique. Both ions were successfully doped into the Zr{sup 4+} ion site in a mixed structure containing both monoclinic and tetragonal phases. The Eu{sup 3+} or Tb{sup 3+} singly doped zirconia produced red and green luminescence which are characteristics of Eu{sup 3+} and Tb{sup 3+} ions, respectively. The co-doped zirconia samples produced blue emission from defect states transitions in the host ZrO{sub 2}, red and green luminescence from dopant ions giving cool to warm white light emissions. The phosphors were efficiently excited by ultraviolet and near-ultraviolet/blue radiations giving white and red light, respectively. The decay lifetime was found to increase with increasing donor ion concentration contrary to conventional observations reported by previous researchers. Weak quadrupole–quatdrupole multipolar process was responsible for energy transfer from Tb{sup 3+} (donor) ion to Eu{sup 3+} ion. No energy back-transfer from Eu{sup 3+} to Tb{sup 3+} ion was observed from the excitation spectra. Temperature-dependent photoluminescence shows the presence of defects at low temperature, but these defects vanished at room temperature and beyond. The Eu{sup 3+}/Tb{sup 3+}-co-doped ZrO{sub 2} nanocrystal rod is a potential phosphor for white light application using UV as an excitation source. Thermoluminescence measurements show that the inclusion of Tb{sup 3+} ion increases trap depths in the host zirconia.

    2004-01-01

    The luminescent properties of an Eu{sup 2+}-activated hexagonal aluminate, BaMgAl{sub 10}O{sub 17} (BAM), were studied under 147- and 254-nm excitations. The BAM samples were thermally treated by baking and then irradiated in vacuum ultraviolet (VUV) rays. The results show that the emission efficiency of Eu{sup 2+} in BAM under 147-nm excitation degraded seriously after baking or VUV-irradiating treatments, while no significant degradation was observed under 254-nm excitation. The degree of degradation depended on the excitation wavelength, and the absorption edge of the BAM host was suggested to be close to 175 nm (7.2 eV). The differences between the thermal-induced and the VUV-irradiation-induced degradations, and their mechanisms are discussed for the color plasma display applications.

    Tin and zirconium silicates have been prepared with Sn/Si and Zr/Si molar ratios of 1 and 0.75, respectively. Kinetics and exchange studies of Zn 2+ and Eu 3+ ions on the prepared stannous and zirconium silicates have been carried out as a function of reaction temperature, particle diameters, solution concentration of the exchanging cations from water and alcohol-water mixture. The capacity of the exchangers for the studied cations from alcohol-water mixture was found higher than in pure aqueous solutions. The rate of exchange was dependent on particle diameters and independent on concentration of metal ions. The kinetic and thermodynamic parameters, vis. effective diffusion coefficients, activation energies and entropies of activation have been evaluated. Negative values of entropy, enthalpy and free energy of activation for Zn 2+ /M + and Eu 3+ /H + on both exchangers have been recorded at different conditions

    Full Text Available Corporate governance ensures that boards are able to exercise appropriate scrutiny over management and that shareholders, as owners of the company, are able to hold boards accountable. As such, a high level of corporate governance contributes significantly to investors' confidence and market stability, thus fostering business efficiency. In 2005 the European Commission launched a recommendation on the boards of listed companies and invited Member States to follow the guidelines. In 2008 both Romania and Hungary launched a new Code of Corporate Governance on the basis of the EU recommendations. In my paper I present the EU principles, and by examining the national codes of Romania and Hungary I analyze to which extent and in what issues these two countries have adopted the EU recommendations. I concluded that by the new codes of corporate governance issued in 2008 Romania and Hungary have followed to a large extent the provisions of the EU recommendation.

    Yellow-emitting phosphor mat consisting of Ca{sub 0.68}Si{sub 9}Al{sub 3}(ON){sub 16}:Eu{sup 2+} microbelts was prepared by electrospinning and subsequent nitridation. The as-prepared fiber precursor is smooth and uniform with diameter of 800 to 900 nm. After removing organic templates and nitridation, the morphology of the fiber is well retained and thus a smooth microbelts phosphor mat was obtained. X-ray diffraction and the photoluminescence (PL) spectra reveals that a relatively pure Ca{sub 0.68}Si{sub 9}Al{sub 3}(ON){sub 16} phase and the highest spectral intensity could be obtained at a relatively low temperature of 1500 °C and Eu{sup 2+} doping molar concentration of 0.1. The excitation spectra exhibits a broad band, ranging from 300 to 550 nm, which could be excited by blue LED chip at room temperature. The emission spectra of all exhibits a single broad band in the 400 to 700 nm region, with the maximum intensity always being at 580 nm. The Ca{sub 0.68}Si{sub 9}Al{sub 3}(ON){sub 16}:Eu{sup 2+} microbelts phosphor mat has the bending strength about 4.5 MPa with a photoluminescence quantum yield as high as 65%. By employing it as yellow phosphor, a high-performance warm white LED could be fabricated with low correlated color temperature (2985 K), high-color-rendering index (Ra=86) and luminous efficacy of 129.5 lm W{sup −1}. Different color temperatures also could be tuned by employing microbelts phosphor mats with different thicknesses. - Graphical abstract: Yellow-emitting phosphor mat consisting of Ca{sub 0.68}Si{sub 9}Al{sub 3}(ON){sub 16}:Eu{sup 2+} microbelts fibers were prepared by electrospinning the fiber precursor and subsequent nitridation.

    Full Text Available This article describes the discipline of missiology and mission over the last century since Edinburgh 1910 followed by two world wars to Edinburgh 2010, as a long walk to obedience – a walk in discerning God’s will. Even in biblical times, mission as spreading the gospel to those who do not yet believe in the Trinitarian God, was under scrutiny from within and outside the church (cf. Ac 10-11, 15 and Galatians. Throughout history until today it was never different. This article looks at the development of mission over the last 100 years from a Western (mainline missionary churches – MMCs perspective. The development of missiology as a subject and theological discipline will be described along the lines of some of the mission conferences. Attention will be given to the following questions: What does it mean to b eobedient to the mission calling in a broken and traumatised world? Is there a credible way of redeeming mission and missiology from its own past?

    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.

    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.

    As part of the storage of nuclear wastes in a deep underground disposal, radionuclides sorption on geological or engineered barriers is one of the most important factor which could enhance retardation. Thus, the knowledge of such mechanisms is needed. For this purpose, we chose to experimentally define sorption equilibria before performing simulation of retention data. Several phosphate compounds are potential candidates as engineered barrier additives. We considered Th{sub 4}(PO{sub 4}){sub 4}P{sub 2}O{sub 7}, Zr{sub 2}O(PO{sub 4}){sub 2} which allow to study the effect of PO{sub 4} and P{sub 2}O{sub 7} groups separately. Eu(III) and U(IV) ions were used as structural probes in order to simulate actinides (III) and (VI) behavior. X-ray powder diffraction, IR spectroscopy and electron probe microanalysis were used to characterized the synthesized solids. Electrophoretic measurements showed an amphoteric behavior of surface sites. Moreover, laser spectro-fluorimetry experiments indicated that no diffusion phenomena of the sorbed ion inside the solid occurs. Thus, we considered that a surface complexation model should be applied. Laser spectro-fluorimetry and XPS allowed to determine the nature of surface sites. ZrP{sub 2}O{sub 7} presents only one single site (P{sub 2}O{sub 7} groups) whereas Th{sub 4}(PO{sub 4}){sub 4}P{sub 2}O{sub 7} and Zr{sub 2}O(PO{sub 4}){sub 2} admit two types of sites (PO{sub 4}/P{sub 2}O{sub 7} and PO{sub 4}/oxo groups, respectively). Sorbed species were identified using laser spectro-fluorimetry which indicate that, in KNO{sub 3} 0.5 M medium and for a known surface site, there are two surface complexes for U(VI) (sorption of UO{sup 2+}{sub 2} et de UO{sub 2}NO{sup +}{sub 3} species) and only one for Eu(III) (sorption of EuNO{sup 2+}{sub 3}). They are linked to the substrate as bidentate inner sphere complexes (EXAFS study). Surface acidity constants were determined by simulation of potentiometric titration curves obtained for each solid

  11. 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.

    The work presented here is an experimental investigation of the biokinetics of transfer of a transuranic and a rare earth element ( 238 Pu and 152 Eu) in the lobster Homarus gammarus. The study of 238 Pu biokinetics forms part of a wider framework of research concerning the transfer of transuranic elements in marine species, while the study of 152 Eu is carried out with a view to supporting the analogy between the behaviour of transuranics and rare earths in living organisms. Exactly the same experimental protocol, based on techniques from various disciplines (biology, biochemistry and metrology), was used to Investigate the biokinetics of transfer of these two radionuclides. The Individual lobsters were radiolabelled by means of one-shot or chronic ingestion of spiked meals. As the first approach, the kinetics and transfer mechanisms were studied In whole animal samples and in different organs distinct series of pathways through the different organs were identified in the case of both radionuclides, being mainly linked to digestive processes induced by the meal as well as the transport function of hemo-lymph in this way, the Important role of the digestive gland was picked out, with two of four cellular types displaying a successive involvement In the fixation and then the retention of the studied radionuclides. As a corroborative approach, the digestive gland was subjected to a more detailed investigation with the aim of describing the mechanisms of Incorporation and elucidating transfer processes at the cellular and molecular levels. 238 Pu is preferentially partitioned into the cytosol, where it is associated with various constituents such as ferritin (iron-storing protein). 152 Eu is more diffusely distributed in the hepato-pancreatic cells, while the lysosomes appear to play a more important role during transfer. The results obtained in this study, both on the macroscopic scale (i.e. the whole animal and different organs) as well as the cellular and molecular

    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

    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.

  2. Assessing the Sustainability of EU Timber Consumption Trends: Comparing Consumption Scenarios with a Safe Operating Space Scenario for Global and EU Timber Supply

    Directory of Open Access Journals (Sweden)

    Meghan O’Brien

    2017-12-01

    Full Text Available The growing demand for wood to meet EU renewable energy targets has increasingly come under scrutiny for potentially increasing EU import dependence and inducing land use change abroad, with associated impacts on the climate and biodiversity. This article builds on research accounting for levels of primary timber consumption—e.g., toward forest footprints—and developing reference values for benchmarking sustainability—e.g., toward land use targets—in order to improve systemic monitoring of timber and forest use. Specifically, it looks at future trends to assess how current EU policy may impact forests at an EU and global scale. Future demand scenarios are based on projections derived and adapted from the literature to depict developments under different scenario assumptions. Results reveal that by 2030, EU consumption levels on a per capita basis are estimated to be increasingly disproportionate compared to the rest of the world. EU consumption scenarios based on meeting around a 40% share of the EU renewable energy targets with timber would overshoot both the EU and global reference value range for sustainable supply capacities in 2030. Overall, findings support literature pointing to an increased risk of problem shifting relating to both how much and where timber needed for meeting renewable energy targets is sourced. It is argued that a sustainable level of timber consumption should be characterized by balance between supply (what the forest can provide on a sustainable basis and demand (how much is used on a per capita basis, considering the concept of fair shares. To this end, future research should close data gaps, increase methodological robustness and address the socio-political legitimacy of the safe operating space concept towards targets in the future. A re-use of timber within the economy should be supported to increase supply options.

  3. The EU pledge for responsible marketing of food and beverages to children: implementation in food companies.

    Jensen, J D; Ronit, K

    2015-08-01

    Increasing political pressure on the food industry's marketing activities stimulated the formation of the collective EU Pledge for responsible marketing of foods and beverages to children. The objective of the study is to evaluate the commitments made by companies in joining the pledge for the purpose of assessing its effectiveness in regulating signatory companies' marketing activities. Data on company commitments in relation to the EU Pledge were collected, analyzed and recalculated in order to enable comparison across companies and with general nutritional recommendations. Data on companies' product portfolio and market orientation were collected from their most recent available annual reports. Data on the companies' product profiles were generated via review of the companies' main websites. Similar data were generated for a reference group of companies outside the EU Pledge. Compared with a reference group of large food and beverage companies, EU Pledge signatory companies have a public image strongly based on products with appeal to children. The EU Pledge sets common standards for regulating signatory companies' marketing behaviour towards children. Further scrutiny of the companies' stated commitments revealed considerable variation in their actual content and in their de facto bindingness on the companies' marketing behavior--for example, in the definition of target audience for advertising or in nutritional characteristics making products eligible for advertising to children. In order for voluntary self-regulation schemes such as the EU Pledge to be a credible alternative to public regulation of marketing behaviour, more transparency and stringency are needed.

    Adequate provision of information is essential for decision making. This paper provides the results of the quality assessment of Environmental Impact Statements (EIS), documents prescribed by EIA Directive (337/85/EEC). The assessment was completed by several categories of reviewers in Estonia, which has been an EU member state since 2004. The quality assessment of EIS was based on the EC Guidance on EIS Review (2001). Firstly, the quality assessment of 50 randomly selected EIS was carried out by a single reviewer. Secondly, the individual grading among 24 independent reviewers of a single EIS was tested. Thirdly, a comparison of the results of 15 individual and 5 group assessments of the same EIS was conducted. The results from the quality assessment of the selected EIS demonstrate a satisfactory level of information provided for decision making; 68% of the sample EIS were positively graded. However, more than half of the 50 EIS were graded as 'just satisfactory'. Comparison between the individual and group assessment of the same EIS demonstrates that the group assessment is more critical than the individual assessment. This possibly results from a wider technical expertise and balancing of subjective values and perspectives among group members. Arguably, the current practice of EIA competent authorities assessing the quality of EIS with individuals could be revised. We discuss the effect of the group assessment on expanding the narrow technical expertise and the subjectivity of a single expert.

  10. 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

    2012-05-01

    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.

    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)

    during most of the period since the early 1990s, when aid flows from the EU started growing. Regarding trade relations, we note that the EU’s increasing use of antidumping tariffs against Vietnamese exporters during the past years could be an indication of a less friendly and more competitive attitude...... was limited to aid. The reason is largely Vietnam’s historical experiences from the aid relationship with the Soviet Union, which created dependence and eventually an economic crisis when aid flows dried up in the late 1980s.

    EuFe{sub 2}As{sub 2} is an extraordinary parent compound of the iron pnictides, as it exhibits at low temperatures - additional to the Fe spin density wave - long-range magnetic order of the Eu{sup 2+} local moments. Nevertheless, bulk superconductivity around 30 K can be induced by mechanical pressure or chemical substitution. In this talk we review the remarkable interplay of unconventional superconductivity, itinerant and local magnetism in Eu based iron pnictides. We focus on the appearance of a re-entrant spin glass phase that coexists with superconductivity and an indirect magneto-elastic coupling, enabling the persistent magnetic detwinning by small magnetic fields.

  5. EU Emission Trading - better job second time around?

    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

    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 ...

    With constant incentives for healthcare payers to contain their pharmaceutical budgets, forecasting has become critically important. Some countries have, for instance, developed pharmaceutical horizon scanning units. The objective of this project was to build a model to assess the net effect of the entrance of new patented medicinal products versus medicinal products going off-patent, with a defined forecast horizon, on selected European Union (EU) Member States' pharmaceutical budgets. This model took into account population ageing, as well as current and future country-specific pricing, reimbursement, and market access policies (the project was performed for the European Commission; see http://ec.europa.eu/health/healthcare/key_documents/index_en.htm). In order to have a representative heterogeneity of EU Member States, the following countries were selected for the analysis: France, Germany, Greece, Hungary, Poland, Portugal, and the United Kingdom. A forecasting period of 5 years (2012-2016) was chosen to assess the net pharmaceutical budget impact. A model for generics and biosimilars was developed for each country. The model estimated a separate and combined effect of the direct and indirect impacts of the patent cliff. A second model, estimating the sales development and the risk of development failure, was developed for new drugs. New drugs were reviewed individually to assess their clinical potential and translate it into commercial potential. The forecast was carried out according to three perspectives (healthcare public payer, society, and manufacturer), and several types of distribution chains (retail, hospital, and combined retail and hospital). Probabilistic and deterministic sensitivity analyses were carried out. According to the model, all countries experienced drug budget reductions except Poland (+€41 million). Savings were expected to be the highest in the United Kingdom (-€9,367 million), France (-€5,589 million), and, far behind them

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

    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.

  12. Legal aspects of the EU policy on irregular immigration

    2015-12-01

    Full Text Available This article addresses the issues pertaining to the adoption and development of legislation on irregular migration in the context of uncontrolled growth in the number of immigrants from North Africa and the Middle East to the EU. The article attempts at studying the EU legislation on irregular migration, classifying it, and analysing the prospects of EU migration legislation in the light of an increase in irregular immigration into the EU. The author systematises, classifies the current EU legislation on irregular immigration, and analyses the conditions, in which this legislation was developed. Using the legislation analysis method, the author proposes the following system of EU legislation on irregular immigration: rules preventing assistance to irregular immigration, rules preventing employment of irregular immigrants, rules on the return of irregular migrants and readmission, rules on border control, and rules on collaboration with third countries. The author pays special attention to analysing the current state of irregular immigration to the EU, which was dubbed the ‘greatest migration crisis in Europe’. The conclusion is that the European Union succeeded in the development of pioneering legislation on irregular immigration, which can serve as the basis for reception by other states. However, changes in the political and economic situation in the EU’s southern borderlands made the current legal mechanisms incapable of withstanding new threats. It necessitates a radical reform of the legislation on irregular immigration.

First, we review the mechanisms and determinants of vertical specialization (VS, as this has gradually become the dominant characteristic of international trade. Second, we underline that there is a rich literature regarding VS in EU trade, at aggregate and individual levels and research is advancing together with the instruments used to measure trade in value added. Third, our investigation brings to the forefront a classification of EU countries according to their GVC participation index, taking into consideration both upstream and downstream links. As a conclusion, the VS analyses help us better understand the interconnectedness among countries and industries by means of foreign direct investment, trade, labour migration and technology transfer.

    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

  16. Lost in Implementation: EU Law Application in Albanian Legal System

    Hajdini Bojana

    2017-06-01

    Full Text Available Considering the growing importance of the researchers in the area of Europeanization in the candidate countries, the purpose of this paper is to analyse whether, and to what extent EU as a legal normative power has influenced Albania to approximate existing and future legislation and to ensure proper implementation. The paper argues that the Europeanization process is pushing Albania toward greater convergence with EU acquis by developing a modern legal framework. However, the paper points out that weak implementation has hampered the application of EU law in Albania due to: a weak bureaucracy or uneven distribution of human capacities; b the lack of an established practice of consultation with interest groups on specific draft legislation, and c the inability to put in sound planning mechanisms and to carry out a realistic assessment. The paper concludes that effective adjustment of Albanian legal system with EU norms requires cooperation between different actors involved in the approximation and implementation process.

    Full Text Available The article is dedicated to implementation of the enhanced cooperation in the EU. Actually two such projects are шn progress (the law applicable to divorce and legal separation and unitary patent protection and other two are under discussionffmandai transaction tax and European Public Prosecutor's Office. Active use of the enhanced cooperation recently shows that such kind of the promoting integration is more and more required in the EU. However its implementation can jeopardize the principles of the EU functioning and undermine the status of the institutions in the integration process. This mechanism can also be used in order to exclude the discordant states from integration process instead of traditional search of compromises. This argument is based on analysis of the implementation conditions of the project on the unitary patent protection. At the same time the projects of the enhanced cooperation obviously make the interaction in different spheres more efficient. In addition they can be used for testing the new types of cooperation. That's why the search for an optimal balance between promotion integration through the mechanism of enhanced cooperation and preserving the unity of the EU should be considered as main goal by participants of the integration process. Otherwise the gradual separation on the vanguard group may lead to EU division. Nevertheless taking into consideration enlargement of the EU and its diversity, the enhanced cooperation Should be used onlyas "extreme measure".

    Full Text Available On average, EU countries allocate 6.4% of total public expenditure for the direct support of the public sector at all levels of education. In view of a more rational allocation of resources seriously diminished by the crisis there are made efforts to identify educational areas considered problematic in terms of accessing various education programs. This paper presents pre-school funding policies and policies to support families with preschool and school age children in the European Union through a comparative analysis of the focus group type. There are also presented concrete ways of achieving that family support such as tax cuts, family allowances or by taking into account certain factors in order to establish fees. In all countries where taxes are paid for pre-compulsory education (ISCED A there is a mechanism by which parental contributions can be adjusted according to the means available taking into account criteria such as family income, number of children, family status (children who live with one parent geographic area, etc.

    Full Text Available In recent years European Commission has developed a set of documents for Members States tracing, directly or indirectly, recommendations for the transformation of the European city. The paper wants to outline which future EU draws for the city, through an integrated and contextual reading of addresses and strategies contained in the last documents, a future often suggested as Smart City. Although the three main documents (Cohesion Policy 2014-2020 of European Community, Digital Agenda for Europe and European Urban Agenda face the issue of the future development of European cities from different points of view, which are respectively cohesion social, ICT and urban dimension, each of them pays particular attention to urban and territorial dimension, identified by the name of Smart City. In other words, the paper aims at drawing the scenario of evolution of Smart Cities that can be delineated through the contextual reading of the three documents. To this end, the paper is divided into three parts: the first part briefly describes the general contents of the three European economic plan tools; the second part illustrates the scenarios for the future of the European city contained in each document; the third part seeks to trace the evolution of the Smart Cities issue developed by the set of the three instruments, in order to provide the framework of European Community for the near future of our cities.

    Luminescent and scintillation properties of polystyrene-based plastic scintillators with {beta}-diketone Eu complexes are investigated. A scintillator with dibenzoylmethane Eu complex containing two phenyl groups demonstrates the maximum scintillating efficiency. It is shown that plastic scintillators efficiency is dramatically decreased if {beta}-diketone derivatives contain no phenyl groups as substituents. This fact can be explained by exciplex mechanism of energy transfer from a matrix to Eu complex. - Highlights: > Fluorescent properties of polystyrene scintillators with {beta}-diketone complexes of Eu were studied. > Scintillating efficiency is increased with the number of phenyl groups in Eu complex. > This is related to exciplex mechanism of energy transfer from a polymer matrix to Eu complex.

  5. Does Male Circumcision Protect against Sexually Transmitted Infections? Arguments and Meta-Analyses to the Contrary Fail to Withstand Scrutiny.

    We critically evaluate a recent article by Van Howe involving 12 meta-analyses that concludes, contrary to current evidence, that male circumcision increases the risk of various common sexually transmitted infections (STIs). Our detailed scrutiny reveals that these meta-analyses (1) failed to include results of all relevant studies, especially data from randomized controlled trials, (2) introduced bias through use of inappropriate control groups, (3) altered original data, in the case of human papillomavirus (HPV), by questionable adjustments for "sampling bias," (4) failed to control for confounders through use of crude odds ratios, and (5) used unnecessarily complicated methods without adequate explanation, so impeding replication by others. Interventions that can reduce the prevalence of STIs are important to international health. Of major concern is the global epidemic of oncogenic types of HPV that contribute to the burden of genital cancers. Meta-analyses, when well conducted, can better inform public health policy and medical practice, but when seriously flawed can have detrimental consequences. Our critical evaluation leads us to reject the findings and conclusions of Van Howe on multiple grounds. Our timely analysis thus reaffirms the medical evidence supporting male circumcision as a desirable intervention for STI prevention.

    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.

  9. High-Precision Measurement of Eu/Eu* in Geological Glasses via LA-ICP-MS Analysis

    Elemental fractionation during laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) analysis has been historically documented between refractory and volatile elements. In this work, however, we observed fractionation between light rare earth elements (LREEs) and heavy rare earth elements (HREEs) when using ablation strategies involving large spot sizes (greater than 100 millimeters) and line scanning mode. In addition: (1) ion yields decrease when using spot sizes above 100 millimeters; (2) (Eu/Eu*)(sub raw) (i.e. Europium anomaly) positively correlates with carrier gas (He) flow rate, which provides control over the particle size distribution of the aerosol reaching the ICP; (3) (Eu/Eu*)(sub raw) shows a positive correlation with spot size, and (4) the changes in REE signal intensity, induced by the He flow rate change, roughly correlate with REE condensation temperatures. The REE fractionation is likely driven by the slight but significant difference in their condensation temperatures. Large particles may not be completely dissociated in the ICP and result in preferential evaporation of the less refractory LREEs and thus non-stoichiometric particle-ion conversion. This mechanism may also be responsible for Sm-Eu-Gd fractionation as Eu is less refractory than Sm and Gd. The extent of fractionation depends upon the particle size distribution of the aerosol, which in turn is influenced by the laser parameters and matrix. Ablation pits and lines defined by low aspect ratios produce a higher proportion of large particles than high aspect ratio ablation, as confirmed by measurements of particle size distribution in the laser induced aerosol. Therefore, low aspect ratio ablation introduces particles that cannot be decomposed and/or atomized by the ICP and thus results in exacerbated elemental fractionation. Accurate quantification of REE concentrations and Eu/Eu* requires reduction of large particle production during laser ablation. For the reference

  10. Russian energy in the EU market: Bolstered institutionsand their effects

    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

    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.

  13. 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.

    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.

  15. Sharing Lessons Learned Between Industries in EU

    2012-01-01

    Recent events in nuclear industry remind us on importance of continuous sharing of the knowledge and experience gained through evaluations of incidents and accidents. We frequently use experience from our daily life activities to improve our performance and avoid some mistakes or unwanted events. In the similar way we can use other industries experience. These experiences can be applied to improve nuclear safety. For example, Safety Culture, which has a great influence on the level of nuclear power plants safety, is similarly presented in other industries. Mechanisms which led to accidents from weak safety culture in one branch of other industry could be comparable to those in nuclear industry. Some other industries have many more cumulative years of experience than nuclear industry. Aviation and Oil industries are typical representatives. Part of their experience can be used in nuclear industry too. Number of reports from nuclear power plants showed us that not only specific equipment related causes lay behind accidents; there are also other causes and contributors which are more common for all industries. Hence lessons learned in other industry should be assessed and used in nuclear industry too. In the European Union, a regional initiative has been set up in 2008 in support of EU Member State nuclear safety authorities, but also EU technical support organizations, international organizations and the broader nuclear community, to enhance nuclear safety through improvement of the use of lessons learned from operational experience of nuclear power plants (NPPs). The initiative, called ''the EU Clearinghouse on Operational Experience Feedback for NPP'', is organized as a network operated by a centralized office located at the Joint Research Centre of the European Commission. The reduction of occurrence and significance of events in NPPs and their safe operation is its ultimate goal. Among others EU Clearinghouse provides services such as technical and scientific

    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

    2015-09-01

    Full Text Available Legal frameworks exist within democracies to prevent the misuse and abuse of personal data that law enforcement authorities obtain from private communication service providers. The fundamental rights to respect for private life and the protection of personal data underpin this framework within the European Union. Accordingly, the protection of the principles and safeguards required by these rights is key to ensuring that the oversight of State surveillance powers is robust and transparent. Furthermore, without the robust scrutiny of independent judicial review, the principles and safeguards guaranteed by these rights may become more illusory than real. Following the Edward Snowden revelations, major concerns have been raised worldwide regarding the legality, necessity and proportionality standards governing these laws. In 2014, the highest court in the EU struck down the legal framework that imposed a mandatory duty on communication service providers to undertake the mass retention of metadata for secret intelligence and law enforcement authorities across the EU. This article considers the influence of the Snowden revelations on this landmark judgment. Subsequently, the analysis explores the significance of this ruling for the future reform of EU law governing metadata surveillance and its contribution to the worldwide debate on indiscriminate and covert monitoring in the post-Snowden era.

  18. Antitrust rules and Intellectual Property Rights in the EU and the US – Towards convergence?

    2014-07-01

    Full Text Available In light of the exponential increase of the number of investigations raising the issue of how to reconcile competition rules and Intellectual Property Rights (IPRs, it is now clear that the area of Antitrust/IP intersection is becoming the battleground of antitrust enforcers around the Globe. In some areas inherently prone to market power accumulation, antitrust rules tend to clash with IPRs and prevail over the latter, for the intensity in the application of competition rules increasingly depends on the strength of the IPRs at stake, as well as on the sector involved. Information Communication Technology and Pharmaceuticals are the sectors most affected by this trend, as they both display specific market features calling for intensive antitrust scrutiny. Surprisingly enough, in these areas the EU and the US agencies are heading towards convergence, in light of the decisions taken in cases such as the judicial injunctions sought by FRAND-pledged SEPs holders and the reverse settlements in the Pharma sector. The purpose of this article is to show that in those areas more exposed to tension between antitrust and IP rules, there is an increasing level of convergence between the US and the EU. In particular, it is submitted that, like in the EU, the US is departing from the traditional symmetry principle under which antitrust rules are applied to IPRs exactly the same way as other property rights. In this new framework, inconsistency is more likely to come from the enforcement activity of NCAs across Europe.

    Graphical abstract: Rice-shaped BaAlF 5 :Eu 2+ nanophosphors were synthesized via one-pot hydrothermal process. 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

    2014-01-01

    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

    strained EuO thin film shows a Poisson ratio of ν EuO ∼ 0. The tensile strain reduces the Curie temperature significantly by 12.3 K. The MCD effect provides an advanced magnetic characterization: the MCD asymmetries in Eu core-level photoemission reveal a larger reduction due to the tensile strain than obtained from bulk-averaging SQUID measurements. Thus, the mechanism of tensile strain on intra-atomic exchange (indicated by MCD) is significantly different than on the spin order of the 4f 7 shell (indicated by SQUID). Experiments on EuO by MCD, thereby, reveal exciting perspectives for studying fundamental magnetic properties of EuO. In the second part of this thesis, we explore how to integrate EuO directly with Si (001). We focus on interface engineering of structural and chemical properties of the EuO/Si (001) spin-functional heterointerface. In response to the extremely high chemical reactivity and pronounced surface kinetics of Eu, EuO, and Si during EuO synthesis at elevated temperatures, we initially conduct a thermodynamic analysis of the EuO/Si interface. In this way, we decide to investigate three in situ passivation techniques for the Si (001) surface, in order to prevent metallic and oxide contaminations at the EuO/Si interface. both being main antagonists for spin-selective tunneling. We conduct a comprehensive optimization study of the EuO/Si heterointerface by tuning the passivation parameters of the Si (001) surface and the growth parameters of EuO. Using HAXPES, we evaluate Si and Eu core-level spectra and determine the minimum of interface contaminants as d opt (SiO x ) = 0.69 nm concomitant with d opt (EuSi 2 ) = 0.20 nm, both of which are clearly in the subnanometer regime. In conclusion, our ultrathin EuO/Si (001) heterostructures reveal a high chemical quality of the spinfunctional interface, combined with magnetic properties of the EuO layer akin to bulk. By selected interface passivation methods, we achieve a reduction of residual contaminations

    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.

    A new method of the absolute measurement for 152 Eu was established based on the 4πβ-γ spectroscopic anti-coincidence method. It is a coincidence counting method consisting of a 4πβ-counter and a Ge(Li) γ-ray detector, in which the effective counting efficiencies of the 4πβ-counter for β-rays, conversion electrons, and Auger electrons were obtained by taking the intensity ratios for certain γ-rays between the single spectrum and the spectrum coincident with the pulses from the 4πβ-counter. First, in order to verify the method, three different methods of the absolute measurement were performed with a prepared 60 Co source to find excellent agreement among the results deduced by them. Next, the 4πβ-γ spectroscopic coincidence measurement was applied to 152 Eu sources prepared by irradiating an enriched 151 Eu target in a reactor. The result was compared with that obtained by the γ-ray spectrometry using a 152 Eu standard source supplied by LMRI. They agreed with each other within the error of 2%. (author)

    2010-09-01

    Full Text Available The WTO has an innovative system of dispute settlement, with the following features: sui-generis, integrated, resolving the disputes according to the WTO agreements, excluding unilateral solutions, interstate system. These features are detailed in the present article. Another level of analysis concerns the standing of the EU in the WTO, in general, and in the Geneva proceedings for dispute settlement, in particular. Generated by the quality of the European Communities statute as an original member of the Organisation, the EU has become one of the main users of the WTO dispute settlement system. One of the main challenges of the WTO dispute settlement mechanism is the implementation of decisions. In view of the cases assessed, while the execution record of the EU is a quite satisfactory one, it is apparent that implementation of decisions in more intricate cases creates difficulties at the Union level.

    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.

    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.

    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

    Faced with the mounting evidence of the harmful effects of climate change, the European Union is convinced that the world must take urgent action to tackle the problem. That is why the EU has been at the forefront of international efforts to deal with climate change for well over a decade. The EU is convinced that the status quo is simply not an option. Without urgent, concerted action, the problem will continue to get worse with potentially disastrous consequences. That is why the European Union has consistently taken the lead in international moves to tackle climate change and why it will continue to develop this strategy for as long as it takes to guarantee a world for ourselves and our children where everyone can grow, breathe and live in safety

Some authors have wondered if this concept is a fashion, comprising some older ideas and principles, while other authors have asserted that the reasons why different methods of governance appear in the EU are based on “the complexity and the uncertainty of the problems on the agenda, an irreducible, the new approaches on public administration and law, hidden competencies, legitimacy and subsidiarity”. At a normative level, the White Paper of European Governance consecrated five principles on which good governance is based upon: openness, participation, responsibility, efficiency and coherence.

    Full Text Available Eurozone has gone through turmoil of sovereign debt crisis just after the detrimental effect of global financial crises of 2007/2008. Sovereign debt crisis of the eurozone was caused by bank-sovereign interdependence and lack of fiscal union in the eurozone. Financial fragmentation in the eurozone financial markets was an immediate outcome. Banking union of the EU is a regulatory and institutional remedy for main financial problems of the eurozone post global financial crisis. It is clear signal that lessons have been learned from the two crises. Stricter regulation (single rule book aims to increase the quality of banks. Single Supervisory Mechanism (SRM, and Single Resolution Mechanism (SRM aim to unify and better the standards of supervision and resolution in the EU. With emphasis on bail-ins, and EU level backstops, bank-sovereign interdependence should be dismantled and chances of financial crisis reoccurrence with huge costs for taxpayers should be significantly lower. There are important elements of Banking Union that could be introduced in non-eurozone transition countries both members and nonmembers of the EU.

    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

    In this work, we report permanent reduction of Eu{sup 3+} to Eu{sup 2+} in sodium borate glasses by irradiation of near-infrared femtosecond laser. Glass composition of sodium borate was 85B{sub 2}O{sub 3}-15Na{sub 2}O. The glasses were doped with 0.05, 0.1, and 0.5 mol% Eu{sub 2}O{sub 3}. Absorption and fluorescence dynamics were studied to investigate valence state change of europium ions and the energy transfer between Eu{sup 2+} and Eu{sup 3+} ions. As the femtosecond laser intensity or exposure time increases, the emission band at 400 nm becomes stronger. However, the photoreduction efficiency decreases as the dopant concentration increases. We discuss the photoreduction mechanism under multiphoton absorption.

    Highlights: → Photoionization behavior of BaMgSiO 4 :Eu 2+ long persistent phosphor upon UV irradiation. → Green phosphorescence was obtained from BaMgSiO 4 :Eu 2+ . → The ionization of Eu 2+ to Eu 3+ was observed in BaMgSiO 4 :Eu 2+ . → The photogenerated Eu 3+ cannot change back to its divalent state at room temperature. → The phosphorescence is associated with the formation forming Eu 3+ -e - pairs. - Abstract: The fluorescence, phosphorescence and thermoluminescence properties of Eu-doped BaMgSiO 4 phosphors sintered in air and in a reducing atmosphere were investigated. Phosphorescence of phosphor sintered in a reducing atmosphere can last for 1.5 h at a recognizable intensity level, whereas phosphorescence of air-sintered phosphor can only persist for 6 min. In addition, a distinction between the shape of the fluorescence spectrum and its corresponding phosphorescence spectrum is observed in the former case. Ionization of Eu 2+ to Eu 3+ upon UV irradiation is observed in the phosphor prepared in a reducing atmosphere, but there is no indication that the photogenerated Eu 3+ cannot change back to its divalent state at room temperature after the excitation source is switched off. In addition, phosphor sintered in a reducing atmosphere shows photochromism upon UV irradiation. No such photoionization and photochromism behavior is observed for the air-sintered phosphor. A possible Eu 2+ photoionization mechanism is constructed on the basis of these experimental observations. The photoionization mechanism presented can also successfully explain the fluorescence and phosphorescence behavior of Eu in BaMgSiO 4 .

    Highlights: • Ca{sub 2}BO{sub 3}Cl doped with Eu{sup 2+} prepared by solid state reaction. • Concentration quenching studied by intensity and lifetime measurements. • Accurate determination of the critical transfer distance. • Interaction mechanism verified to be dipole–dipole interactions. - Abstract: With the aim of determining the concentration quenching mechanism of Eu{sup 2+} doped Ca{sub 2}BO{sub 3}Cl, a series of phosphors with a varied Eu{sup 2+} concentration (Ca{sub 2−x}BO{sub 3}Cl:xEu{sup 2+}) was synthesized by the solid state reaction method. The phase structure was determined by X-ray diffraction. Photoluminescence (PL) measurements showed broad excitation and emission signatures of the allowed f–d transition of Eu{sup 2+} ions. The PL emission intensity was found to be increased by increasing the concentration of Eu{sup 2+} ions up to x = 0.03 and then decreased as a result of the concentration quenching effect. The lifetime of the emission from the Eu{sup 2+} ions was measured and the decrease in the lifetime with increasing Eu{sup 2+} concentration confirmed that non-radiative energy transfer occurred between Eu{sup 2+} ions. From the luminescence data, the value of the critical transfer distance was calculated as 1.5 nm and the corresponding concentration quenching mechanism was verified to be a dipole–dipole interaction.

    Full Text Available Red-emitting phosphors Ba2-xMgSi2O7: Eux3+ was prepared by combustion-assisted synthesis method and an efficient red emission under near-ultraviolet (UV was observed. The luminescence and crystallinity were investigated using luminescence spectrometry and X-ray diffractometer. The emission spectrum shows that the most intense peak is located at 614 nm, which corresponds to the 5D0 → 7F2 transitions of Eu3+. The phosphor has two main excitation peaks located at 394 and 465 nm, which match the emission of UV and blue light-emitting diodes, respectively. The effect of Eu3+ concentration on the emission spectrum of Ba2MgSi2O7:Eu3+ phosphor was studied. The results showed that the emission intensity increased with increasing Eu3+ concentration, and then decreased because of concentration quenching. The critical quenching concentration of Eu3+ in Ba2MgSi2O7: Eu3+ phosphor is about 0.05 mol. The mechanism of concentration quenching of Ba2MgSi2O7: Eu3+ luminescence is energy transfer between Eu3+ ions casued by the dipole-dipole interaction.

  11. EU's CO2 trade a high risk project

    International Nuclear Information System (INIS)

    2003-01-01

    The uncertainty about the planned CO 2 trade of the European Union (EU) is very great. For the possible buyers in this politically created market the risks may be great and difficult to assess. The most effective way of forcing a reduction of emissions is trading emission licences. But this requires taking a stand on issues of very unpleasant nature. And the Kyoto protocol evades these questions, it is a thin document right from the beginning. Trade in emission licences is one of the three so-called flexible mechanisms of the Kyoto agreement. The second mechanism is joint implementation in which one industrialized country carries out emission reduction actions in another industrialized country. The third is the mechanism of clean development, in which one industrialized country takes remedial actions in a developing country. It is unclear how these mechanisms are to act in accordance with each other, both in the Kyoto Protocol and on the level of the EU. The biggest and most fundamental uncertainty, both on the EU and global levels, relates to the fact that the partners have not decided how to define the right of ownership of emissions of a certain size

    2013-01-01

    A series of Ca6AlP5O20 doped with rare earths (Eu and Ce) and co-doped (Eu, Ce and Eu,Mn) were prepared by combustion synthesis. Under Hg-free excitation, Ca6AlP5O20:Eu exhibited Eu(2+) (486 nm) emission in the blue region of the spectrum and under near Hg excitation (245 nm), Ca6AlP5O20:Ce phosphor exhibited Ce(3+) emission (357 nm) in the UV range. Photoluminescence (PL) peak intensity increased in Ca6AlP5O20:Eu,Ce and Ca6AlP5O20:Eu, Mn phosphors due to co-activators of Ce(3+) and Mn(2+) ions. As a result, these ions played an important role in PL emission in the present matrix. Ca6AlP5O20:Eu, Ce and Ca6AlP5O20:Eu, Mn phosphors provided energy transfer mechanisms via Ce(3+) → Eu(2+) and Eu(2+) → Mn(2+), respectively. Eu ions acted as activators and Ce ions acted as sensitizers. Ce emission energy was well matched with Eu excitation energy in the case of Ca6AlP5O20:Eu, Ce and Eu ions acted as activators and Mn ions acted as sensitizers in Ca6AlP5O20:Eu, Mn. This study included synthesis of new and efficient phosphate phosphors. The impact of doping and co-doping on photoluminescence properties and energy transfer mechanisms were investigated and we propose a feasible interpretation. Copyright © 2012 John Wiley & Sons, Ltd.

    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.

    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.

  18. EU Trade Governance and Policy: A Critical Perspective

    Directory of Open Access Journals (Sweden)

    Lucy Ford

    2013-10-01

    Full Text Available This article offers a critical analysis of EU trade policy. It does so by highlighting the political and economic enclosures within which EU trade policy is embedded and that continue to hamper more holistic and interdisciplinary analyses that are argued to be necessary in order to comprehend the obstacles to and avenues towards a more sustainable and socially just world. The article critically analyses economic and political hegemony by drawing on two strands of critical international thought, namely neo-Gramscian analysis and global political ecology, employing a critical realist approach. The article identifies the perceived twin short-comings of conventional analyses: firstly, the neglect of understandings of power relations and social justice, and secondly the lack of attention to criteria of sustainability. Within critical debates about European governance, including the governance of trade and trade policy, neo-Gramscian perspectives highlight the power relations within EU governance, exposing the mechanisms of hegemony as well as identifying potential counter-hegemonic forces. While this offers important insights, the article argues that a critical perspective cannot be complete without attention to sustainability. Political ecology makes a vital contribution to critical perspectives by highlighting the natural limits within which by necessity all human activity takes place. Using illustrations from trade policy debates, the article argues that current EU trade policy and governance is not best placed to meet the challenges of sustainability and social justice and it points to the need for more holistic systems thinking to challenge orthodoxy.

    EU energy policies have changed focus in the last few years with a view to substantially reducing energy import dependency and greenhouse gas emissions. The EU Commission has played a leading role in defining the new orientations. The implementation of the EU policy objectives approved by the Council of March 2007 will require a substantial expansion of energy investments. However, the degree of uncertainty affecting investment decisions remains high, notably in relation to the pricing of CO2...

  4. Improving inter-transmission compensation in EU

    International Nuclear Information System (INIS)

    Stoilov, Dimo; Stoilov, Luben

    2013-01-01

    This article is intended as a roadmap to the correction of the existing shortcomings in the EU power transmission tariff system, especially in the existing mechanism of Inter-Transmission System Operator (TSO) Compensation (ITC). The relevant literature is surveyed and the essence of the issue is formulated. Definitions, preconditions, assumptions and constraints for the problem are explained. The paper outlines the most simple and straightforward approach for the improvement of inter-transmission compensation in the Continental European Synchronous Area. The proposals are based on the old practice of socialization of the network costs retained in almost all European countries, i.e. the principle of charging the customers “at the exit”. Equal treatment is given to internal users and cross-border users: a TSO is reimbursed for both internal and cross-border flows from the users conjoined to its network on an equal footing with the users extracting power from the peripheral nodes. The existing inequity in individual payments for power transmission is overcome and the cross-border subsidy element is avoided. This approach should be tested (modeled and evaluated) with real data for the European union of networks. Some key parts of the article are written in a more popular style, in order to be accessible to inexpert readers as well. -- Highlights: •A roadmap to the correction of the shortcomings in the EU power transmission tariff system. •Simple and straightforward approach for improvement of ITC in the European synchronous area. •Equal treatment to internal and cross-border users avoiding cross-subsidies. •Formalization and illustration of the approach. •Real data tests for the European interconnected systems should be performed

  8. EU environmental policy and competitiveness

    Directory of Open Access Journals (Sweden)

    Stojanović Boban

    2006-01-01

    Full Text Available Protection of the environment was not a specific importance to the Community although the Treaty of Rome expressly specified that "health, safety environmental protection" shall be based on "a high level of protection". In deciding upon a framework for a European environmental policy, the Community was also responding to increased public awareness of the problem and concerns about the state of the natural and man-made environment. During the past years, competitiveness concerns have dominated the EU policy debate, in the course of which a growing consensus is being developed on the importance of eco-innovations and resource efficiency for EU competitiveness and on the market opportunities they offer. There is an increasing evidence that environmental policy and eco-innovations can promote economic growth, as well as maintain and create jobs, contributing both to competitiveness and employment. Environmental constraints to rapid economic growth are increasingly recognized by countries, leading to a rising awareness of the need for sustainable development. Implementation of an environmental policy however, generates significant implications for competition among countries.

  9. Renewable energies in the EU

    International Nuclear Information System (INIS)

    Heller, W.

    2008-01-01

    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.)

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

  16. Policy options for carbon taxation in the EU

    International Nuclear Information System (INIS)

    Laurent, Eloi; Le Cacheux, Jacques

    2010-06-01

    Even though the EU clearly leads the global fight against climate change and despite the additional reduction in emissions due to the global crisis and European recession, the ambitious objectives flagged in the '20-20-20 by 2020' strategy and 'climate-energy package' are probably out of reach if a more resolute and consistent policy of carbon taxation is not rapidly put in place. First, the EU is not as 'virtuous' as it may seem, and shows signs of a 'fatigue' in mitigating climate change; this is explained by the weak incentive structure of current climate institutions, due to both narrow coverage and insufficient stringency of the European 'Emission Trading Scheme' (ETS) - the European 'carbon market'-, and to excessive reliance on emission standards combined with weak energy taxation. Fears of losing competitiveness are a major argument against imposing a higher carbon price on industries, feeding tax competition both within the EU and vis-a-vis the rest of the world. Though not fully satisfactory, the Commission's recent proposal (a revision of the 2003 energy taxation directive introducing floors on national excises based on carbon content) would help solving the intra-EU conundrum. Alternatively, an extension of the EU ETS to households and the transport sector via the 'upstream' inclusion of fossil fuel dealers would also be a feasible solution. In order to answer the 'carbon leakage' argument and to send appropriate price signals to European consumers on extra-EU imports, a border adjustment mechanism - carbon levy or inclusion of importers into the EU ETS - is also necessary. Ultimately though, in order to make sure that economic agents face a uniform carbon price, a generalized carbon tax, in the form of a European 'Carbon Added Tax' (ECAT), would be the most effective instrument in the fight against climate change, as well as the pillar of a thorough tax

  8. Intra-EU Direct Investment and Enlargement

    Directory of Open Access Journals (Sweden)

    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 spectral-luminescent properties of CsI-BaCl 2 (1 mol%)-Eu(0.02 mol%) crystalline system are studied. Europium ion doped BaCl 2 microcrystals embedded in a CsI matrix are revealed on CsI-BaCl 2 (1 mol%)-Eu(0.02 mol%) freshly cleaved surface by the scanning electron microscopy. The size of microcrystals is shown to be within 0.5–5 microns. The luminescent parameters of the BaCl 2 -Eu 2+ microcrystals are shown to be similar to ones of a single crystal analogue. The 4f → 5d absorption transitions in europium ions and the reabsorption of the intrinsic emission of the CsI host are the main excitation mechanisms of europium luminescence in the BaCl 2 microcrystals. -- Highlights: ► The formation of chloride BaCl 2 :Eu microcrystals in the case of BaCl 2 doped CsI crystal has been revealed. ► The observed size of microcrystals at BaCl 2 concentration of 1% is about 0.5–5 μm. ► Majority of Eu 2+ ions in CsI-BaCl 2 -EuCl 3 crystalline system enters into BaCl 2 microcrystals. ► The luminescent parameters of the BaCl 2 :Eu 2+ microcrystals and its bulk analogue are similar

    Emissions trading listed as a flexible mechanism under the Kyoto Protocol is regarded as a market economy way in climate protection. Since 2005 the European Emissions Trading System (EU ETS) is the central climate policy instrument for reducing the emissions of greenhouse gases, in particular for carbon dioxide (CO{sub 2}). For years, however, the CO{sub 2} price is too low to direct the politically and socially targeted technical innovations in the electricity sector and the industry. The article analyses the temporary and structural causes of this problem, highlights the EU's reform efforts and points to areas of activity, the basis of which the EU ETS may act in the future as a central instrument for climate protection in the European Union. [German] Der im Kyoto-Protokoll als flexibler Mechanismus aufgefuehrte Emissionshandel gilt als marktwirtschaftlicher Weg in den Klimaschutz. Das Europaeische Emissionshandelssystem (EU ETS) ist seit 2005 das zentrale klimapolitische Instrument zur Senkung des Ausstosses von Treibhausgasen, insbesondere fuer Kohlenstoffdioxid (CO{sub 2}). Seit Jahren ist der CO{sub 2}-Preis jedoch zu gering, um die politisch und gesellschaftlich angestrebten technischen Innovationen im Stromsektor und der Industrie zu lenken. Der Artikel untersucht die temporaeren und strukturellen Ursachen dieses Problems, beleuchtet die Reformbestrebungen der EU und zeigt Handlungsfelder auf, anhand derer das EU ETS auch in Zukunft als zentrales Instrument fuer Klimaschutz in der Europaeischen Union fungieren kann.

    The WHO Global Code of Practice on the International Recruitment of Health Personnel provides for guidance in health workforce management and cooperation in the international context. This article aims to examine whether the principles of the voluntary WHO Global Code of Practice can be applied to trigger health policy decisions within the EU zone of free movement of persons. In the framework of the Joint Action on European Health Workforce Planning and Forecasting project (Grant Agreement: JA EUHWF 20122201 (see healthworkforce.eu)), focus group discussions were organised with over 30 experts representing ministries, universities and professional and international organisations. Ideas were collected about the applicability of the principles and with the aim to find EU law compatible, relevant solutions using a qualitative approach based on a standardised, semi-structured interview guide and pre-defined statements. Based on implementation practices summarised, focus group experts concluded that positive effects of adhering to the Code can be identified and useful ideas-compatible with EU law-exist to manage intra-EU mobility. The most relevant areas for intervention include bilateral cooperations, better use of EU financial resources, improved retention and integration policies and better data flow and monitoring. Improving retention is of key importance; however, ethical considerations should also apply within the EU. Compensation of source countries can be a solution to further elaborate on when developing EU financial mechanisms. Intra-EU circular mobility might be feasible and made more transparent if directed by tailor-made, institutional-level bilateral cooperations adjusted to different groups and profiles of health professionals. Integration policies should be improved as discrimination still exists when offering jobs despite the legal environment facilitating the recognition of professional qualifications.

    EuO is a widely studied magnetic semiconductor. It is an ideal case of a Heisenberg ferromagnet as well as a model magnetic polaron system. The interesting aspect of this material is the existance of magnetic polarons in the low temperature region. We study the properties of oxygen deficient EuO prepared by pulsed laser deposition. Besides normal ferromagnetic transitions near 70K and 140K, we observe a different transition at 16K. We also observe a shift in the coercivity for field cooling versus zero field cooling. Possible mechanisms driving these behaviors will be discussed. This work was supported by the U.S. Department of Energy, Office of Basic Energy Sciences, Division of Materials Sciences and Engineering (DEFG02-10ER46728) and by the School of Energy Resources of the University of Wyoming.

    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

    We present an efficient way to search a host for ultraviolet (UV) phosphor from UV nonlinear optical (NLO) materials. With the guidance, Na 3 La 2 (BO 3 ) 3 (NLBO), as a promising NLO material with a broad transparency range and high damage threshold, was adopted as a host material for the first time. The lanthanide ions (Tb 3+ and Eu 3+ )-doped NLBO phosphors have been synthesized by solid-state reaction. Luminescent properties of the Ln-doped (Ln=Tb 3+ , Eu 3+ ) sodium lanthanum borate were investigated under UV ray excitation. The emission spectrum was employed to probe the local environments of Eu 3+ ions in NLBO crystal. For red phosphor, NLBO:Eu, the measured dominating emission peak was at 613 nm, which is attributed to 5 D - 7 F 2 transition of Eu 3+ . The luminescence indicates that the local symmetry of Eu 3+ in NLBO crystal lattice has no inversion center. Optimum Eu 3+ concentration of NLBO:Eu 3+ under UV excitation with 395 nm wavelength is about 30 mol%. The green phosphor, NLBO:Tb, showed bright green emission at 543 with 252 nm excited light. The measured concentration quenching curve demonstrated that the maximum concentration of Tb 3+ in NLBO was about 20%. The luminescence mechanism of Ln-doped NLBO (Tb 3+ and Eu 3+ ) was analyzed. The relative high quenching concentration was also discussed

    A family of apatite-type fluorophosphate phosphors with general formula Sr3Gd(1-m-n)Na(PO4)3F:mTb3+,nEu3+ (SGN:mTb3+,nEu3+) have been synthesized via the high-temperature solid-state reaction method. Triple energy transfer processes from Gd3+ in the host to both Tb3+ and Eu3+, as well as from Tb3+ to Eu3+ have been verified by the photoluminescence spectra. Under the excitation of UV light, both green line from the transitions of Tb3+ and red line origin from the transitions of Eu3+ have been simultaneously observed in a single phase phosphor, which makes a promise for tunable color emissions from yellowish-green through yellow and ultimately to reddish-orange by simply adjusting the Eu3+ content (n) in SGN:0.20Tb3+,nEu3+ phosphors. Additionally, the energy transfer from the Tb3+ to the Eu3+ ions has been demonstrated to be a resonant type via a quadrupole-quadrupole mechanism based on the Dexter's theoretical model, and the energy transfer efficiency increases with an increase in Eu3+ concentration.

    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.

    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

    When I began to write this book, I originally had in mind the needs of university students in their first year. May aim was to keep the mathematics simple. No advanced techniques are used and there are no complicated applications. The emphasis is on an understanding of the basic ideas and problems which require expertise but do not contribute to this understanding are not discussed. How­ ever, the presentation is more sophisticated than might be considered appropri­ ate for someone with no previous knowledge of the subject so that, although it is developed from the beginning, some previous acquaintance with the elements of the subject would be an advantage. In addition, some familiarity with element­ ary calculus is assumed but not with the elementary theory of differential equations, although knowledge of the latter would again be an advantage. It is my opinion that mechanics is best introduced through the motion of a particle, with rigid body problems left until the subject is more fully developed. Howev...

    A new compound Eu 2 Pt 3 Si 5 with plate shaped morphology has been grown from excess In flux. The compound crystallizes in the orthorhombic U 2 Co 3 Si 5 structure type, Ibam space group and the lattice parameters are a=10.007(2) Å, b=11.666(2) Å and c=6.0011(12) Å. The crystal structure of this compound can be conceived as inter-twinned chains of [Pt 2 Si 2 ] and [PtSi 3 ] tetrahedra connected along [100] direction to give rise to a complex three dimensional [Pt 3 Si 5 ] network. Temperature dependent magnetic susceptibility data suggests that Eu 2 Pt 3 Si 5 undergoes a strong antiferromagnetic ordering (T N =19 K) followed by a weak ferromagnetic transition (T C =5.5 K). The effective magnetic moment/Eu obtained from susceptibility data is 6.78 μ B accounts mixed valent Eu with almost 85% divalent Eu, which is supported by X-ray absorption near edge spectroscopy. The compound undergoes a metamagnetic transition under applied magnetic field through a probable spin flop mechanism. - Graphical abstract: Eu 2 Pt 3 Si 5 , a new member in the U 2 Co 3 Si 5 (Ibam) family undergoes metamagnetic transition at high magnetic field and Eu is in mixed valence state. - Highlights: • A new compound Eu 2 Pt 3 Si 5 has been synthesized using indium as an inactive metal flux. • The compound undergoes metamagnetic transition at higher field. • Eu in this compound resides in a mixed valence state

    The sorption of europium(Eu(III)) onto kaolinite and the influence of humic acids over a range of pH 3 ∼ 11 has been studied by batch adsorption experiment (V/m = 250:1 mL/g, CEu(III) = 1x10 -5 mol/L, C HA = 5 ∼ 50 mg/L, PCO 2 = 10 -3.5 atm). The concentrations of HA and Eu(III) in aqueous phase were measured by UV absorbance at 254 nm(e.g., UV 254 ) and ICP-MS after microwave digestion for HA removals, respectively. Results showed that the HA sorption onto kaolinite was decreased with increasing pH and their sorption isotherms fit well with the Langmuir adsorption model (except pH 3). Maximum amount(q max ) for the HA sorption at pH 4 to 11 was ranged from 4.73 to 0.47 mg/g. Europium adsorption onto the kaolinite in the absence of HA was typical, showing an increases with pH and a distinct adsorption edge at pH 3 to 5. However in the presence of HA, Eu adsorption to kaolinite was significantly affected. HA was shown to enhance Eu adsorption in the acidic pH range (pH 3 ∼ 4) due to the formation of additional binding sites for Eu coming from HA adsorbed onto kaolinite surface, but reduce Eu adsorption in the intermediate and high pH above 6 due to the formation of aqueous Eu-HA complexes. The results on the ternary interaction of kaolinite-Eu-HA are compared with those on the binary system of kaolinite-HA and kaolinite-Eu and adsorption mechanism with pH was discussed

    Among the publications of CDC Climat Research, 'Tendances Carbone' bulletin specifically studies the developments of the European market for CO 2 allowances. This issue addresses the following points: The Carbon Market Report published last November by the European Commission launched a debate on structural measures to sustainably address the EU ETS's large surplus and sets out six options for measures which could do so: (a) increasing the EU reduction target to 30% in 2020, (b) retiring a number of allowances in phase 3, (c) early revision of the annual linear reduction factor, (d) extension of the EU ETS to other sectors, (e) limit access to international credits, (f) discretionary price management mechanisms. To assess these options, we must ask: what needs to be improved about the EU ETS's current design?

  6. EU, Eastern Europe and Values Imperialism

    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.

  7. Coordinating the Uncoordinated: The EU Forest Strategy

    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.

  8. IMPACTS OF CLIMATE CHANGE ON EU AGRICULTURE

    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.

    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.

    HARALAMBIE GEORGE ALIN

    2017-08-01

    Full Text Available Social inclusion, a dynamic process of stringent topicality, manifested in the community space, is constituted in a subject with multiple reverberations on contemporary society. From this perspective, the growing interest of the Member States in social inclusion is due to the widening of existing inequalities in terms of people's living standards due to the deterioration of economic well-being. A growing number of studies on social cohesion at the level of the countries of the European Union tried to identify the similarities and disparities between Member States in the process of social inclusion. The paper evaluated and compared the existing disparities between the 28 EU countries, based on a set of social indicators that provide an insight into social inclusion. The methodology used implied a cluster analysis based on the method of k-means, which allowed me to form a grouping of Member States based on indicators of social inclusion. The results of the analysis reveal significant differences between the countries of the European Union regarding social inclusion due to factors of a political, economic and social nature. Understanding the mechanism of manifestation and correction of the level of social inclusion can provide, in this sense, explanations and solutions in capitalizing the economic potential by developing specific policies to the existing social imbalances.

    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.)

  15. Estimating broad-brush rebound effects for household energy consumption in the EU 28 countries and Norway: some policy implications of Odyssee data

    International Nuclear Information System (INIS)

    Galvin, Ray

    2014-01-01

    Currently there is a strong policy commitment in European Union (EU) and Organisation for Economic Co-operation and Development (OECD) countries to increase the energy efficiency of residential buildings, and it is widely assumed that this will naturally and automatically reduce domestic energy consumption. However, other factors such as fuel prices, wages, attitudes and lifestyles also influence energy consumption. This paper calculates broad-brush rebound effects based on changes in energy efficiency and energy consumption in each of the 28 EU countries plus Norway, for the years 2000–2011. In doing so, it tests how well the assumption of energy efficiency leading to energy reduction stands up to scrutiny in these lands. It uses the EU’s Odyssee database for efficiency and consumption figures and a commonly employed econometric definition of the rebound effect as an energy-efficiency elasticity. Most older EU lands show rebound effects in the expected range of 0–50%. However, the range for newer EU countries is 100–550%, suggesting that energy efficiency increases are not a good predictor of energy consumption. A more in-depth look at one country, Germany, suggests these results underestimate the rebound effect significantly. This also identifies research needs for specific energy consumption determinants in each country, to find more precisely what is driving consumption levels. - Highlights: • Policymakers frequently link energy efficiency gains with energy consumption falls. • Household energy rebound effects are calculated for EU lands using Odyssee data. • Most older EU lands show results in the range of 0–50% but newer lands show 100–552%. • Energy efficiency gains are not always a reliable predictor of energy consumption. • Targeted research could explore why consumption is often so unrelated to efficiency

  16. Study of sorption mechanisms of europium(3) and uranium(6) ions on clays : impact of silicates; Etude des mecanismes de retention des ions U(6) et Eu(3) sur les argiles: influence des silicates

    Bentonite clay has been selected as a potential buffer or backfill material in a number of disposal programmes for high level waste. In order to enhance the thermodynamic database of sorption phenomena at the solid-water interface, we have investigated sorption mechanisms of europium(III) and uranium(VI) ions onto montmorillonite and bentonite. Thermodynamic data were obtained for different ions concentrations, different background electrolytes and different ionic strengths. The structural identification of the surface complexes and sorption sites was carried out using two spectroscopies, XPS and TRLIFS, while sorption edges were performed using batch experiments. However, clays are complex minerals and in order to understand these sorption mechanisms we have studied europium(III) and uranium(VI) retention on a silica and an alumina because these solids are often considered as basic components of clays. The comparison of structural results shows that europium ions are significantly sorbed on permanently charged sites of clay until pH 7. But this ion is also sorbed on {identical_to}SiOH and {identical_to}AlOH sites of montmorillonite at pH higher than 6. Uranyl ions sorption on montmorillonite is mainly explained by retention of three complexes on {identical_to}SiOH sites. Moreover, we have shown that nitrate ions and dissolved silicates affect on uranium(VI) sorption mechanisms onto alumina. Nevertheless, uranyl ions sorption on montmorillonite and bentonite only decreases with increasing carbonate concentration. Finally, all the sorption edges were then modeled using these results and a surface complexation model (2 pK and constant capacitance models). (author)

  17. The EU model evaluation group

    1999-01-01

    The model evaluation group (MEG) was launched in 1992 growing out of the Major Technological Hazards Programme with EU/DG XII. The goal of MEG was to improve the culture in which models were developed, particularly by encouraging voluntary model evaluation procedures based on a formalised and consensus protocol. The evaluation intended to assess the fitness-for-purpose of the models being used as a measure of the quality. The approach adopted was focused on developing a generic model evaluation protocol and subsequent targeting this onto specific areas of application. Five such developments have been initiated, on heavy gas dispersion, liquid pool fires, gas explosions, human factors and momentum fires. The quality of models is an important element when complying with the 'Seveso Directive' requiring that the safety reports submitted to the authorities comprise an assessment of the extent and severity of the consequences of identified major accidents. Further, the quality of models become important in the land use planning process, where the proximity of industrial sites to vulnerable areas may be critical.

    Full Text Available The article explores the variety of tools and vehicles applied within the EU to expand the prerogative of the regions of the EU member states. The author uses as an example the inter-regional policies in Belgium in respect of the Flemish Region and the Walloon Region. The author analyzes the mechanisms of promotion of external regional relations in Belgium as a means of addressing different problems both on national and all-European level, supporting the arguments and conclusions by examples of relevant EU initiatives. The article details the activities of the EU Regional Committee (RC, the EU advisory body with the powers of political initiative, upholding the principle ofsubsidarity in the implementation of the EU member states' regional policies. The involvement of the Flemish Region and the Walloon Region in the activities of EU RC is described and summarized. As a case study, the article deals with Belgium's rotating six months presidency in the EUin 2010 when the country, which was going through a severe political crisis with no federal government in place, was represented by the two regions. The special focus of the article is on the strategic EU program "Europe2020" and its implementation by the regions of Belgium. There is an account of the initiatives undertaken by the Flemish Region and the Walloon Region within the framework of this program outlining the interaction of the two regions. The author provides a comprehensive analysis of the involvement of the Flemish Region and the Walloon Region with various EU institutions describing how each party achieves the promotion of its regional interests. Within this context, it is a noteworthy development that the Flemish Region is participating in the international program "Pact 2020" on energy all by its own. The article features quotations by Flemish and Walloon political figures which serve as an illustration of the prevailing attitudes in the Belgian society to the process of

    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

  8. 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.

    This paper explores the incentives for energy efficiency induced by the European Union Emissions Trading Scheme (EU ETS) for installations in the energy and industry sectors. Our analysis of the National Allocation Plans for 27 EU Member States for phase 2 of the EU ETS (2008-2012) suggests that the price and cost effects for improvements in carbon and energy efficiency in the energy and industry sectors will be stronger than in phase 1 (2005-2007), but only because the European Commission has substantially reduced the number of allowances to be allocated by the Member States. To the extent that companies from these sectors (notably power producers) pass through the extra costs for carbon, higher prices for allowances translate into stronger incentives for demand- side energy efficiency. With the cuts in allocation to energy and industry sectors these will be forced to greater reductions, thus the non-ET sectors like household, tertiary and transport will have to reduce less, which is more in line with the cost-efficient share of emission reductions. The findings also imply that domestic efficiency improvements in the energy and industry sectors may remain limited since companies can make substantial use of credits from the Kyoto mechanisms. The analysis of the rules for existing installations, new projects and closures suggests that incentives for energy efficiency are higher in phase 2 than in phase 1 because of the increased application of benchmarking to new and existing installations and because a lower share of allowances will be allocated for free. Nevertheless, there is still ample scope to further improve the EU ETS so that the full potential for energy efficiency can be realized. (orig.)

    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 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.

  3. EU GHG Emission Targets: 'Mind the gap'

    International Nuclear Information System (INIS)

    2012-06-01

    In Durban, the European Union has been able to overcome the traditional dividing lines between developed and developing countries, setting a 'road-map' for a post-Kyoto framework. This would see countries conclude an 'agreed outcome with legal force' on emissions targets by 2015. Was this a key goal or a partial success for EU climate diplomacy? The main concerns are that the second commitment period would only come into force by 2021, and that necessary carbon cuts are not be increased before 2020. The direct by-product for the EU victory has been the awakening of the debate about raising emissions reductions to 30%. In fact, as stated in the Low Carbon Road-map, the EU has adopted a target of cutting emissions by 20% to by 2020, and of moving to a 30% reduction target if the conditions are right. Is this finally the time for Europe to improve its performance, even if it means going it alone? The EU has always been a strong defender of the Kyoto Protocol under certain constraints, such as developing and emerging countries entering into the deal. But does the EU have all the right assets to fight for this? Where is Europe in achieving its 2020 goal? In essence, this paper provides an estimate of what EU emissions could be in 2020, and how they stand compared to Kyoto and 20% objective of the 2020 strategy. (author)

These relatively low investments in Europe are a combination of priority and obstacles. The priority for investments is clearly in Asia, Africa and Latin America. This regional pattern is heavily influenced by the need to solve the resource shortage in the medium and long term. The investments in Europe and the United States are mostly market seeking investments. Research specifically focused on Chinese M&A abroad comes to the same conclusion. The success rate of Chinese M&A abroad is much lower than what we see with respect to American or European investments abroad. In this paper, we examine why Chinese firms are facing more difficulties in the European Union than in other regions. The paper focuses on Chinese M&A as proxy for total foreign direct investments abroad. By looking at the factors that have been documented as influencing the level of M&A abroad, it becomes clear that Chinese firms in Europe are hindered by many factors. For example, the trade between China and the EU is relatively low, the institutional quality is lower compared to the United States, there is less experience with respect to Europe and relatively many deals relate to State Owned Enterprises (SOE which makes the deal sensitive. So it is logical that Chinese investments are not very high in Europe. However, the research makes clear that the obstacles for Chinese investments in Europe are disappearing step by step. In that sense, we expect a strong increase of Chinese investments in Europe in the future.

    Ln 3+ -doped fluoride is a far efficient material for realizing multicolor emission, which plays an important part in full-color displays, biolabeling, and MRI. However, studies on the multicolor tuning properties of Ln 3+ -doped fluoride are mainly concentrated on a complicated process using three or more dopants, and the principle of energy transfer mechanism is still unclear. Herein, multicolor tunable emission is successfully obtained only by codoping with Tb 3+ and Eu 3+ ions in β-NaGdF 4 submicrocrystals via a facile hydrothermal route. Our work reveals that various emission colors can be obtained and tuned from red, orange-red, pink, and blue-green to green under single excitation energy via codoping Tb 3+ and Eu 3+ with rationally changed Eu 3+ /Tb 3+ molar ratio due to the energy transfer between Tb 3+ and Eu 3+ ions in the β-NaGdF 4 host matrix. Meanwhile, the energy transfer mechanism in β-NaGdF 4 : x Eu 3+ /y Tb 3+ (x + y = 5 mol %) submicrocrystals is investigated. Our results evidence the potential of the dopants' distribution density as an effective way for analyzing energy transfer and multicolor-controlled mechanism in other rare earth fluoride luminescence materials. Discussions on the multicolor luminescence under a certain dopant concentration based on single host and wavelength excitation are essential toward the goal of the practical applications in the field of light display systems and optoelectronic devices.

    Graphical abstract: The graphical abstract shows the excitation and emission spectrum of LiCaPO 4 :Eu 2+ , and the CIE coordinates of LiCaPO 4 :Eu 2+ . The inset shows the photo of blue LED prepared by LiCaPO 4 :Eu 2+ and NUV chip. It indicates that this phosphor can be excited by UV light and emit strong greenish-blue light. Highlights: •Pure phase blue phosphors of LiCaPO 4 :Eu 2+ with a hexagonal structure were first prepared via solid-state method. •The crystallographic site of Eu 2+ ion in the LiCaPO 4 lattice was identified as 8-fold Ca 2+ site. •The phosphor exhibits excellent thermal stability and the corresponding mechanism was thermal assisted ionization. •Bright and high color purity blue LED prototype based on LiCaPO 4 :Eu 2+ phosphor was fabricated. -- Abstract: Blue-emitting phosphors of Eu 2+ -activated LiCaPO 4 with a hexagonal structure were prepared via a conventional solid-state method. The XRD, PL spectra and thermal quenching were applied to characterize the phosphors. The crystallographic site of Eu 2+ ion in the LiCaPO 4 lattice was identified and discussed. The optimized LiCaPO 4 :0.03Eu 2+ exhibits the bright greenish-blue emission with CIE coordinates of (0.119, 0.155) and a quantum efficiency of 52%. The critical energy-transfer distance was confirmed as ∼18 Å by both calculated crystal structure method and experimental spectral method. The thermal stability of LiCaPO 4 :Eu 2+ was evaluated by temperature-dependent PL spectra, and the thermal quenching mechanism was found to be thermal assisted ionization. Prototype blue LEDs with high color purity and good current stability were fabricated

    We carry out a detailed computable general equilibrium (CGE) analysis of the EU Decarbonisation Roadmap 2050 on a macroeconomic and on a sectoral level. Herein, we study a Reference scenario that implements existing EU policies as well as 3 unilateral and 3 global climate action scenarios. We identify global climate action with international emissions trading and the full equalisation of CO 2 prices across all (EU) sectors as an economically reasonable policy option to avoid additional costs of the Decarbonisation Roadmap to a large extent. This policy option may include CDM (Clean Development Mechanism in the sense of ‘where’-flexibility) in an extended form if there are countries without emissions caps. Moreover, we identify diverse sectoral effects in terms of output, investment, emissions and international competitiveness. We conclude that the successful realisation of the EU Decarbonisation Roadmap probably requires a wise and joint consideration of technology, policy design and sectoral aspects. - Highlights: ► We extend the CGE model PACE until 2050 and include energy technologies. ► We assess the newest EU Decarbonisation Roadmap in six policy scenarios. ► Global action with ETS and CDM credits from non-participants create low(est) costs. ► Mitigation costs can strongly increase at CO 2 reductions around 80%. ► The policy effects vary strongly across EU sectors

    In this paper, a novel fluorescent probe, dtpa-bis(cytosine), was designed and synthesized for detecting europium (Eu3 +) ion. Upon addition of Eu3 + ions into the dtpa-bis(cytosine) solution, the fluorescence intensity can strongly be enhanced. Conversely, adding other rare earth metal ions, such as Y3 +, Ce3 +, Pr3 +, Nd3 +, Sm3 +, Gd3 +, Tb3 +, Dy3 +, Ho3 +, Er3 +, Yb3 + and Lu3 +, into dtpa-bis(cytosine) solution, the fluorescence intensity is decreased slightly. Some parameters affecting the fluorescence intensity of dtpa-bis(cytosine) solution in the presence of Eu3 + ions were investigated, including solution pH value, Eu3 + ion concentration and interfering substances. The detection mechanism of Eu3 + ion using dtpa-bis(cytosine) as fluorescent probe was proposed. Under optimum conditions, the fluorescence emission intensities of EuIII-dtpa-bis(cytosine) at 375 nm in the concentration range of 0.50 × 10- 5 mol • L- 1-5.00 × 10- 5 mol • L- 1 of Eu3 + ion display a better linear relationship. The limit of detection (LOD) was determined as 8.65 × 10- 7 mol • L- 1 and the corresponding correlation coefficient (R2) of the linear equation is 0.9807. It is wished that the proposed method could be applied for sensitively and selectively detecting Eu3 + ion.

    CsI:Eu{sup 2+} needle crystal layers were produced by Physical Vapour Deposition (PVD). The luminescence properties were studied before and after thermal anneal. It was shown by Electron Paramagnetic Resonance (EPR) that annealing produces Eu{sup 2+} monomer centres, probably starting from Eu clusters in the needle crystalline layers. These centres seem structurally very similar to the Eu{sup 2+} monomer centres in annealed CsBr:Eu{sup 2+} needle layers. They give rise to a narrow luminescence band peaking at about 450 nm (2.76 eV) at room temperature, both under X-ray and UV excitation. The luminescence intensity of as-deposited layers is low. Annealing enhances photo- and radioluminescence on average by a factor of 1.5–3. Surprisingly, further sensitization of radioluminescence with a factor of up to 7 is possible by exposing the annealed needle layers to X-rays or UV, while in contrast, UV excited luminescence is slightly reduced. X-ray enhancement thus leads to a structured scintillator with a conversion efficiency of about 42,000 photons/MeV upon X-ray excitation. A similar radioluminescence enhancement is observed for annealed CsI:Eu{sup 2+} fine powder, but not for large single crystals or conglomerated polycrystals. The measurements and observations are consistent with Eu{sup 2+} monomer centres stabilized by water molecules. These molecules are incorporated via annealing, and that this happens when the morphology is such that water can diffuse throughout the volume of the crystals. The presence of stabilized Eu{sup 2+} monomers is necessary to enhance radioluminescence by X-ray exposure. A mechanism is proposed for the phenomenon.

  18. Competition Law and the Nuclear Sector: An EU Outlook

    International Nuclear Information System (INIS)

    Sousa Ferro, M.

    2010-01-01

    Competition law essentially aims at preventing harmful distortions of competition in the market which may be caused by agreements between companies, by the abusive behaviour of dominant companies, by structural changes in the market due to mergers or by state aid.1 However, often such practices and measures are actually necessary to render certain services viable, to obtain new or better products, to pursue other policies for the greater benefit of the collective, etc. Occasionally, this raises interesting issues in the nuclear sector. This paper aims to provide European competition law practitioners with a summary of the leading legal issues and precedents in this domain, alerting them to relevant specifics. It also aims to introduce nuclear lawyers to the reality and potential of antitrust enforcement in this sector. For the purposes of this paper, the 'nuclear sector' shall be broadly defined so as to include any activity which, given its link to nuclear energy or to ionizing radiation, is (at least partially) subject to special regulation under nuclear law. While many nuclear-related activities will not, in principle, require a special analysis beyond the usual parameters of competition law enforcement, others present distinct challenges to practitioners. Some of these challenges are specific to the European legal order and justify the restriction of the scope of this analysis to the European Union. That being said, the extensive harmonization of the national competition law of member states, as well as the fact that national competition authorities are required to enforce EU competition law, makes it advisable to look simultaneously at European-wide and national antitrust enforcement. The relationship between EU competition law and the nuclear sector remains somewhat shrouded in mystery - perhaps excessively so. The issue has been tackled to some extent in general works on competition law and energy law. As one would expect, research developed in the framework

    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.

    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.

    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.

    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.

    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

    2012-01-01

    Multicolor emission is reported from ultrasmall (<10 nm) β-NaYF4:Eu,Tb nanocrystals depending on the excitation wavelengths or emission detection delay time. Detailed optical investigations of three samples (NaYF4:Eu, NaYF4:Tb and NaYF4:Eu,Tb) obtained by a co-thermolysis method have been carried out. Photoluminescence, photoluminescence excitation and emission decay time obtained at different excitation wavelengths have been measured. Excitation mechanisms of Eu and Tb ions have been explained based on the experimental results and calculations using Judd-Ofelt theory. It has been shown that efficient energy transfer from Tb to Eu ions accounts for the efficient red emission of NaYF4:Tb,Eu nanocrystals. © The Royal Society of Chemistry 2012.

    This paper seeks to explore some of the conditions under which energy policy could be formulated in and by the European Union (EU) over the next 40 years. The development of energy policy at the EU level is addressed from a wider historical perspective, taking into account a number of factors that influence both the EU project and its energy supply security. These factors include the EU's international orientation and cooperation; the EU 'economic community of law' paradigm; the EU's (failing?) external leadership role; the impact of the fall of the Berlin Wall; and Europe's talents for creativity and improvisation. These factors are discussed in somewhat greater depth in the context of the formulation of an all-EU energy policy. The global energy policy environment is briefly discussed, indicating that energy resources for the world are less at stake than their access. On this basis, a closer look is taken at the theoretical and practical aspects of using scenarios as a tool for energy policy-making. A few examples are presented, and it is argued that scenarios should basically be addressed on the basis of storylines. Storylines do require a set of specific parameters, and in this case the choice was made to use the various roles played by stakeholders for intervening in markets and in the world order. This choice is argued on the basis of the global interrelations that are currently influencing resource policies in general and energy in particular. Market efficiency, climate change, poverty issues, geopolitics and global coordination mechanisms are considered, leading to the two policy dimensions of 'nationalism' versus 'globalism' and 'heavy' versus 'light' government as the axes for the scenarios and storylines. This paper develops four storylines that are conceivable and inherently consistent. They are labelled with names that refer not only to their content, but also to the political and

    to describe Australian midwives' experiences of an external review of obstetric services, involvement in legal proceedings and the impact on midwives' clinical practice and personal wellbeing. the external review process (commonly referred to as the 'Douglas Inquiry') was initiated by a state government and was in response to hospital staff and consumer complaints that focused on anomalies in client care and a significantly high rate of adverse outcomes and clinical errors. It took place within the context of a number of legal proceedings against medical practitioners. As a result, some midwives employed by the hospital were called to give evidence at a variety of legal forums. a qualitative study using an explorative descriptive design. Snowball sampling was used to invite 16 Australian midwives to participate in a tape-recorded interview. Thematic analysis and the techniques associated with constant comparison were used to analyse the data. Australian maternity tertiary referral centre. the analysis identified two overarching themes, 'A story of scrutiny' and 'A story of fear', each with a number of subthemes. 'A story of scrutiny' consists of three subthemes. 'A cloak and dagger affair' reflects the midwives' sense of being and feeling 'exposed' and 'vulnerable' whilst simultaneously being 'kept in the dark' and uninformed during the review process. The subtheme 'Being thrown to the wolves' describes the midwives' experiences of being involved, as witnesses, in medico-legal proceedings. The third subtheme, 'The Inquiry followed them home' outlines the effect on midwives' emotional wellbeing and personal relationships. The second major theme, 'A story of fear' again consists of a number of subthemes. 'Feeling unsafe at work: a culture of fear' describes the midwives' experiences of working within an environment they perceive as driven by the fear of litigation. In order to protect themselves and maintain a sense of control, the midwives adopted a number of

    This contribution develops a framework of analysis that covers the actors involved in the policy making process of international security provision, the dynamics of this process itself, its outcomes (concrete strategies and policies) and their impact. Our efforts to establish such a framework...... of analysis, which could serve as the foundation for a mid-range theory of the EU as an international security provider, will examine the relevance of, and apply, existing theories of international relations/international security and foreign policy analysis to the specific case of the EU. The framework...... that will emerge from this analysis will then be tested and applied empirically in the following contributions that focus on how particular policies are formulated and implemented, and that analyse, in single and comparative case studies, the impact and effectiveness of the EU as an international security provider....

    Full Text Available The EU is the world’s largest trade group, occupying an important position in the world trade in goods and services, especially in the field of service trade. The EU trade in services exports and imports are higher than the United States and Japan, and the EU is the world’s largest capital output and input group, and the world’s largest foreign aid providers. With the deepening of the European integration process, Europe’s position in the world economy and trade is on the rise. Therefore, the EU’s trade policy has increasingly become the focus of attention. From the vertical point of view, research directions can be divided into trade in goods policy, trade in services policy, international direct investment policy, trade-related intellectual property policy four field. In this paper, the four vertical areas are illustrated as the focus of the study.

    Full Text Available The paper deals with the EU aid concerning to improved the economic situation from developing countries. Therefore, the aim of this research is to identify how EU states contribute to helping poor countries, members of the World Trade Organization. For the beginning, we define the EU’position before, during and after the Doha Round – a round of WTO multilateral trade negotiations. Moreover, we analyse the development dimension, focusing on countries „marginalized” until early of XXI century in terms of international trade, because this represents the idea-axis of the Doha Round. In this context, the EU – one of the leading global commercial players and a key member of the institution mentioned above – has set several objectives to achieve the basic goal of negotiations and several ways to support developing countries. To conclude, we propose to define the key points of the European aid for least developed and developing countries.

    In this work, we report the preparation, characterization, comparison and luminescence mechanisms of Eu 2 + -doped and Eu 2 + ,Dy 3 + -co-doped Ba 2 MgSi 2 O 7 (BMSO) phosphors. Prepared phosphors were synthesized via a high temperature solid-state reaction method. All prepared phosphors appeared white. The phase structure, particle size, and elemental analysis were analyzed using X-ray diffraction (XRD), transmission electron microscopy (TEM) and energy-dispersive X-ray (EDX) analysis. The luminescence properties of the phosphors were investigated by thermoluminescence (TL) and photoluminescence (PL). The PL excitation and emission spectra of Ba 2 MgSi 2 O 7 :Eu 2 + showed the peak to be around 381 nm and 490 nm respectively. The PL excitation spectrum of Ba 2 MgSi 2 O 7 :Eu 2 + Dy 3 + showed the peak to be around 341 nm and 388 nm, and the emission spectrum had a broad band around 488 nm. These emissions originated from the 4f 6 5d 1 to 4f 7 transition of Eu 2 + . TL analysis revealed that the maximum TL intensity was found at 5 mol% of Eu 2 + doping in Ba 2 MgSi 2 O 7 phosphors after 15 min of ultraviolet (UV) light exposure. TL intensity was increased when Dy 3 + ions were co-doped in Ba 2 MgSi 2 O 7 :Eu 2 + and maximum TL intensity was observed for 2 mol% of Dy 3 + . TL emission spectra of Ba 1.95 MgSi 2 O 7 :0.05Eu 2 + and Ba 1.93 MgSi 2 O 7 :0.05Eu 2 + ,0.02Dy 3 + phosphors were found at 500 nm. TL intensity increased with UV exposure time up to 15 min, then decreased for the higher UV radiation dose for both Eu doping and Eu,Dy co-doping. The trap depths were calculated to be 0.54 eV for Ba 1.95 MgSi 2 O 7 :0.05Eu 2 + and 0.54 eV and 0.75 eV for Ba 1.93 MgSi 2 O 7 :0.05Eu 2 + ,0.02Dy 3 + phosphors. It was observed that co-doping with small amounts of Dy 3 + enhanced the thermoluminescence properties of Ba 2 MgSi 2 O 7 phosphor. Copyright © 2016 John Wiley & Sons, Ltd.

    Optical and spectroscopic properties of 2.0% Eu(PO{sub 3}){sub 3} singly doped and 5.0% Tb(PO{sub 3}){sub 3}–2.0% Eu(PO{sub 3}){sub 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{sup 3+} and Eu{sup 3+}, reddish-orange light emission, with (0.61,0.37) CIE1931 chromaticity coordinates, is obtained upon Tb{sup 3+} excitation at 344 nm. This reddish-orange luminescence is generated mainly by {sup 5}D{sub 0}→{sup 7}F{sub 1} and {sup 5}D{sub 0} →{sup 7}F{sub 2} emissions of Eu{sup 3+}, europium being sensitized by terbium through a non-radiative energy transfer. From an analysis of the Tb{sup 3+} emission decay curves it is inferred that the Tb{sup 3+}→Eu{sup 3+} energy transfer might take place between Tb{sup 3+} and Eu{sup 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{sup +}–Na{sup +} ion exchange, and they could be characterized at various wavelengths. -- Highlights: • Reddish-orange light emission can be generated from Tb{sup 3+} and Eu{sup 3+} codoped zinc–sodium–aluminosilicate glasses excited at 344 nm. • The Eu{sup 3+} is sensitized by Tb{sup 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.

  19. 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

    A piece-shaped phosphor Ca 2 BO 3 Cl: Eu 2+ was synthesized by solid-state reaction method. This phosphor exhibited wide absorption in ultra-violet and visible range, and bright yellow emission band centering at 570 nm. The concentration quenching mechanism was verified to be a dipole–dipole interaction, and its critical transfer distance was about 17 Å by both calculated crystal structural method and experimental spectral method. This phosphor has a good thermal stability with a quenching temperature (T 1/2 ) of 200 °C. Yellow and white LEDs were fabricated with this phosphor and near UV chips, and the yellow LED has a high color purity of 97.0% and promising current tolerant property, while the white LED shows a luminous efficiency of 11.68 lm/W. - Highlights: ► Broadband excitable and strong yellow-emitting Ca 2 BO 3 Cl: Eu 2+ phosphor is obtained by solid state reaction. ► Concentration quenching mechanism of Ca 2 BO 3 Cl: Eu 2+ is dipole–dipole interaction. ► Quenching temperature (T 1/2 ) of Ca 2 BO 3 Cl: Eu 2+ is at 200 °C. ► As synthesized material can be used for LED phosphor application.

  2. Harmful effect of arbitration dispute settlement EU intra bits to the legal order of the European Union

    Directory of Open Access Journals (Sweden)

    Vukadinović Radovan D.

    2017-01-01

    Full Text Available The issue of interpreting and applying intra BITs, especially in cases where their solutions conflict with EU law or international law, are a reflection of the still unresolved relationship between EU law and international law. Despite the exceptional theoretical significance, the issue of hierarchy is, first and foremost, a political issue. The answer to it defines the legal nature of the EU and the direction of its further development: as a sui generis federal community or a regional community of a confederal type. In the legal theory, the opinion on sui generis and the autonomous legal order of the EU is prevalent. This was also confirmed by the Court of Justice in a series of cases. However, the analyzed decisions of investment arbitrations engaged on the basis of the ISDS mechanism call into question such a position. Arbiters believe that the rights and obligations of the BIT should be interpreted in accordance with the rules of international law and that, in the event of a conflict with EU law, priority should be given to the rules of international public law. For this reason, the European Commission and the Court of Justice only see the existence of ISDS clauses in the BITs as a threat to the preservation of the unity and autonomy of the EU legal order, because their activation is jeopardized by the 'interpretative monopoly' of the Court of Justice entrusted with the decision of previous issues to ensure unity of rights EU. The fact that the question of the effect of the ISDS mechanism is not only of theoretical importance is testified by the fact that the EU negotiations on a new generation of trade and investment agreements are examining proposals to establish a more democratic and transparent multilateral international judicial mechanism in place of the existing mechanism.

  9. 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.

  13. 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

    The tritium loading of current grades of advanced ceramic breeder pebbles with three different lithium orthosilicate (LOS)/lithium metatitanate (LMT) compositions (20–30 mol% LMT in LOS) and pebbles of EU reference material, was performed in a consistent way. The temperature dependent release of the introduced tritium was subsequently investigated by temperature programmed desorption (TPD) experiments to gain insight into the desorption characteristics. The obtained TPD data was decomposed into individual release mechanisms according to well-established desorption kinetics. The analysis showed that the pebble composition of the tested samples does not severely change the release behaviour. Yet, an increased content of lithium metatitanate leads to additional desorption peaks at medium temperatures. The majority of tritium is released by high temperature release mechanisms of chemisorbed tritium, while the release of physisorbed tritium is marginal in comparison. The results allow valuable projections for the tritium release behaviour in a fusion blanket.

    Full Text Available The paper gives an overview of the most important EU acts that prohibit the sexual harassment in the workplace and recommend the protection mechanisms. The problem of sexual harassment has been perceived from the aspect of gender (inequality and discrimination while its solution is found in urgeing for consistent implementation of the principle of equal opportunity of women and men in the sphere of labor and employment. For the purpose of providing a comparative insight, it has been also given an overview of national legislative in this domain proceeding by conclusion that only few initial steps in creating the adequate mechanisms of protection from sexual harassment in the workplace have been made so far. .

    BaCl 2 :Eu 2+ microcrystals embedded in the NaCl host have been obtained in the NaCl–BaCl 2 (1 mol%)–EuCl 3 (0.02 mol%) crystalline system. The influence of the annealing conditions on the formation of such particles has been studied. In particular, long-term annealing (at 200 °S during 100 h) promotes the microcrystals formation in the NaCl–BaCl 2 –Eu crystalline system. The subsequent heat treatment (annealed at 600 °S during 72 h and quenched to room temperature) is shown to lead to the destruction of the majority of these particles. The luminescent-kinetic properties of BaCl 2 :Eu 2+ microcrystals have been studied upon the ultra-violet excitation by the synchrotron radiation. The X-ray excited luminescence has been measured in order to estimate the distribution of europium ions between microcrystals and the NaCl host. The excitation mechanisms of Eu 2+ ions in the NaCl–BaCl 2 –Eu crystalline system are discussed. - Highlights: ► The formation of BaCl 2 :Eu 2+ microcrystals of 1–100 μm size embedded in the NaCl host is revealed. ► Annealing at 600 °C leads to the destruction of significant number of embedded microcrystals. ► The luminescent parameters of microcrystals is similar to ones of single crystal analogs.

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.

    2014-01-01

    Full Text Available The results of the Vilnius summit of the EaP project and the consequent Ukrainian crisis with major international effects make possible questioning about the eventual scenarios of the EU eastern politics and possible configurations ofinternational interactions. The article elaborates on the key elements and trends of the EU activities at the post-soviet space that are likely to frame the context of its further developments. The most visible trends analysed here are the extreme differentiation of bilateral relations within the EaP project alongside with the growing symbolism of official rhetoric and program practices of the European Union. As a result, we see the EU's intention to narrow the geographical and qualitative field of its activities on the eastern directionwith saving the shell of the EaP for nominal functioning. Such tactics is not likely to result in a drastic change of the model of conflict dependencies in the "shared neighbourhood". The article analyses key misperceptions of the actors involved in the complex of interactions in the region. The structure is complicated by the deepening and widening of Russia-lead Eurasian integration project. Current crisis of the EU eastern policy is considered to derive from the exaggeration of the value-based, normative aspect of the common foreign policy in general and will have the systemic consequences both for the European external actions and for its internal developments.

    Eu 3+ is often used as a structural probe, because of the relative simplicity of its energy-level structure and dependence on its site symmetry in the host material. The phonon energy of the host for rare-earth ions is a crucial factor to be considered for developing luminescent materials.Thorium molybdate can satisfy both low phonon energy environment for rare-earth ions and good chemical and mechanical stabilities for practical use. Thus Eu 3+ doped Th(MoO 4 ) 2 are expected to be a good promising optical materials. To the best of our knowledge, there is no report on optical spectroscopy of Eu 3+ doped thorium molybdate and thus work has been carried out and discussed in this paper

  17. The EU and Climate Change Policy: Law, Politics and Prominence at Different Levels

    Directory of Open Access Journals (Sweden)

    Chad David Damro

    2008-11-01

    Full Text Available The European Union (EU is a prominent player in the politics of climate change, operating as an authoritative regional actor that influences policy-making at the national and international levels. The EU’s climate change policies are thus subjected to multiple pressures that arise from the domestic politics of its twenty-seven individual member states and the international politics of non-EU states with which it negotiates. Facing these multiple pressures, how and why could such a non-traditional actor develop into a prominent player at different levels of climate change policy-making? This article argues that the EU’s rise to prominence can be understood by tracking a number of historical-legal institutional developments at the domestic and international levels. The article also provides a preliminary investigation of the EU emissions trading scheme, a new institutional mechanism that illustrates the policy pressures arising from different levels.

    2015-01-01

    Emissions trading listed as a flexible mechanism under the Kyoto Protocol is regarded as a market economy way in climate protection. Since 2005 the European Emissions Trading System (EU ETS) is the central climate policy instrument for reducing the emissions of greenhouse gases, in particular for carbon dioxide (CO 2 ). For years, however, the CO 2 price is too low to direct the politically and socially targeted technical innovations in the electricity sector and the industry. The article analyses the temporary and structural causes of this problem, highlights the EU's reform efforts and points to areas of activity, the basis of which the EU ETS may act in the future as a central instrument for climate protection in the European Union.

    2008-10-01

    If the EU stands alone in adopting climate policy and imposes a strict emissions ceiling, competitiveness of EU energy-intensive sectors will be affected negatively. Relocation of EU energy-intensive firms to countries with a lax regime also leads to carbon leakage. However, when use is made of the opportunities of the Clean Development Mechanism these impacts are very modest. Border tax adjustments (BTAs) to 'level the playing field' between domestic and foreign producers may be considered to address the concerns about both competitiveness and carbon leakage. It is far from clear whether these measures are WTO-proof. Simulations show that both an import levy and an export refund restore competitiveness to a certain extent. BTAs may lower the costs for energy-intensive sectors, but induce higher costs for other sectors. This paper uses a general equilibrium model to quantify and assess the implications of a number of policy scenarios

    2005-08-01

    Full Text Available For each country, joining the union is a unique process, considering advantages and disadvantages which a country can thus obtain. In order to fulfill conditions for the EU accession, transition countries must achieve different convergence criteria. Expansion of the EU brings along many challenges including coordination of policies and conducting a common monetary policy. After joining the EU new members are expected to have a minimum of two years of participation in the Exchange Rate Mechanism 2 before accepting euro. ERM2 can be a flexible and efficient framework for the determination of a appropriate level of irrevocable exchange rate fixing according to euro, as well as for achieving macroeconomic stability. Even though, considering demands for complete abolition of capital controls and high capital mobility, fixed exchange rate with fluctuation margins of ±15% is to become sensitive to the capital movements and speculative attacks.

    Radiation-induced defects in SrB 4 O 7 :Eu 2+ (0.033 at.%) single crystal irradiated with γ and X-ray quanta has been studied. The induced optical absorption in the 400-700 nm region has been ascribed to F + centers. The Eu 2+ ions have been shown to act simultaneously as traps and as radiative recombination centers of charge carriers. Basing on the thermally stimulated luminescence (TSL), optical absorption and photoluminescence studies of SrB 4 O 7 :Eu 2+ crystals, a TSL mechanism has been proposed associated with the decay of F + centers being in non-equivalent crystallographic positions followed by radiative recombination of charge carriers on europium ions. Various positions of localization of the radiation-induced defects in the SrB 4 O 7 crystal structure have been discussed

    Climate and Energy Framework will have an impact, our study suggests that the ambition of EU and Member State policies is either a continuation of business as usual in terms of rates of progress, or is being dialed down in some cases. The EU and Member State policy should significantly revise their approach to decarbonization by refocusing on the key drivers of emissions in each sector. The EU's new Energy Union Governance Mechanism should be designed based on this principle and current proposals to implement the 2030 package should be adopted in the strongest possible form to put the EU back on track. The EU, in coordination with the Member States, should develop a suite of sectoral policies to complement the overarching emissions caps of the EU ETS and non-ETS sectors

  3. 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.

    We propose an efficient bioimaging strategy using Yb 3+ ,Er 3+ ,Eu 3+ -triplet doped YVO 4 nanoparticles which were synthesized with polymer as a template. The obtained particles possess nanoscale, uniform, and flexible excitation. The effect of Eu 3+ ions on the luminescence properties of YVO 4 :Yb 3+ ,Er 3+ ,Eu 3+ was investigated. The upconversion mechanism of the prepared material was also discussed. The structure and optical properties of the prepared material were characterized by using X-ray diffraction (XRD), Fourier-transform IR spectroscopy (FTIR), scanning electron microscopy (SEM), Transmission electron microscopy (TEM) upconversion and photoluminescence spectra. The Commission International de I′Eclairage (CIE) chromaticity coordinates was investigated to confirm the performance of color luminescent emission. The prepared YVO 4 :Yb 3+ ,Er 3+ ,Eu 3+ nanoparticles could be easily dispersed in water by surface modification with cysteine (Cys) and glutathione (GSH). The aqueous dispersion of the modified YVO 4 :Yb 3+ ,Er 3+ ,Eu 3+ exhibits bright upconversion and downconversion luminescence and has been applied for bioimaging of HeLa cells. Our developed material with dual excitation offers a promising advance in bioimaging. - Highlights: • Prepared particles possess nanoscale size, uniform, and larger scale. • The material exhibits strong emission under dual mode excitations. • The surface material has been applied for bioimaging of HeLa cell. • Low cytotoxicity, no auto-fluorescence

    Eu3+ doped bismuth gadolinium tungstate (BGW), a simplest member of Aurivillius family of layered perovskites, was synthesized by solid-state reaction method. Structural characterisation has been performed by X-Ray diffraction (XRD), Raman spectroscopy, Fourier Transform Infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). Band gap of the host matrix has been calculated using reflectance and absorption spectra. Three different mechanisms were found to explain the excitation of Eu3+ ions and are described in detail. Photoluminescence (PL) spectra of the BGW phosphor doped with Eu3+ ions consist of major emission lines associated with 5D0 → 7FJ (J = 0, 1, 2, 3 and 4) of Eu3+ ion. Site selective PL excitation and emission indicates that Eu3+ ions doped in BiGdWO6 are sensitive to the excitation wavelength without change in the structure. Change in emission spectra were observed when the excitation wavelength was changed. Judd-Ofelt (J-O) parameters were determined from the indirect method to interpret the interactions between the host and dopant ions along with detailed analysis of lifetime measurements.

    A new bis-Schiff base ligand, N,N -bis-(4-N-aminothiourea-2-amylidene)-4,4 -diaminodiphenyl ether (ARADE), was synthesized. Its complex with Eu 3+ in DMF emits the intrinsic fluorescence of Eu 3+ . The fluorescence intensity of the Eu 3+ -ARADE system was enhanced about 60-fold by the addition of hexamethylene tetramine (NMTM) and potash alum. This is a new fluorescence enhancement phenomenon. The excitation and emission wavelengths are 375 nm and 615 nm, respectively. Under optimal conditions, the fluorescence intensities vary linearly with the concentration of Eu 3+ in the range of 7.8x10 -9 -1.75x10 -5 mol L -1 with a detection limit of 5.2x10 -9 mol L -1 , or with the concentration of Al 3+ in the range of 3.1x10 -7 -9.7x10 -5 mol-L -1 with a detection limit of 2.7x10 -7 mol L -1 . The interferences of some rare earth metals and other inorganic ions were described. This method was applied to the determination of Eu 3+ in high purity yttrium oxide and the analysis of AI 3+ in alloy steel standard samples. The mechanism of fluorescence enhancement was also studied. (author)

  7. Russia-EU energy efficiency cooperation in the Baltic region: the untapped potential

    Directory of Open Access Journals (Sweden)

    Romanova T. A.

    2014-03-01

    Full Text Available A stereotypical understanding of EU-Russia energy relations is often reduced to trade in oil and natural gas, which downplays the importance of energy efficiency cooperation. Such cooperation is promoted within the Energy Charter and its Treaty, Partnership and Cooperation Agreement, Energy Dialogue, Common Economic Space, Partnership for Modernisation. However, it lacks practical development, which relates to the instability of the legal environment in Russia, insufficient mechanisms of financial support for energy conservation projects and poor political support. Nevertheless, energy efficiency cooperation is capable of changing Russia-EU energy cooperation qualitatively: it offers a cheaper way to meet the needs of the EU, redefines interdependence between the parties, and introduces new elements of equality between them. Energy efficiency cooperation also transforms the patterns of the EU-Russia legal harmonization, creates new conditions for the convergence of regulations and the development of the middle class in Russia. Due to its specific features, cooperation in the Baltic Sea region becomes a locomotive of the Russia-EU energy efficiency cooperation, and, as a result, is capable of changing the quality of relations between the partners.

  8. EU Floods Directive implementation in Austria

    2016-01-01

    Full Text Available Floods have the potential to cause fatalities, displacement of people and damage to the environment, to severely compromise economic development and to undermine the economic activities of the Community. The EU Directive on the assessment and management of flood risks [2007/60/EC] was adopted on 23 October 2007. Its aim is to reduce and manage the risks that floods pose to human health, the environment, cultural heritage and economic activity. The paper reflects on how the requirements of the FD had been achieved in Austria and how the nationwide comparability and transferability of results as well as the international coordination had been obtained. Austria as a federal state has its competences structured in different departments as well as administrational levels. Besides administrational characteristics there is also a high diversity in topographical boundary conditions from Alpine areas to lowland areas emphasising different approaches and foci of flood risk management. To harmonise the related interests a discussion and decision committee had been established. The resolutions of this committee then defined the basis for a national coordination procedure where the Federal Ministry provided a “federal blueprint” to the federal provinces. The federal provinces then incorporated their regional and local information and data. Based on this response the coordinated and nationwide comparable FRMP had been set up and had been forwarded to public information and consultation. Complementary stakeholder involvement has been ensured by information and discussion workshops throughout the entire process. The administrational and topographical characteristics to be considered in the frame of FD implementation strengthened the coordination and harmonisation across all sectors and stakeholders related to flood risk management. The FD implementation, therefore, is a holistic attempt to outline the needs for action for all sectors related to risk

    The surface charge characteristics of Na-rectorite (NaAl{sub 4}[Si,Al]{sub 8}O{sub 20}(OH){sub 4}.nH{sub 2}O;) were studied by potentiometric acid-base titrations. Sr(II) and Eu(III) adsorptions on Na-rectorite as a function of pH, ionic strength, and Sr(II)/Eu(III) concentrations were carried out to investigate the surface interactions between Sr(II)/Eu(III) with Na-rectorite. The results indicated that the adsorptions of Sr(II) and Eu(III) on Na-rectorite increased with increasing pH and decreased with increasing ionic strength and initial Sr(II)/Eu(III) concentrations, and that the affinity of Na-rectorite for Eu(III) was much higher than for Sr(II). The experimental data of Sr(II)/Eu(III) adsorption were simulated by the diffuse-layer model (DLM) well with the aid of FITEQL 3.2. Simultaneous adsorptions of Sr(II) and Eu(III) on Na-rectorite were also modeled using the DLM. The adsorption mechanisms of Sr(II) and Eu(III) on Na-rectorite may be dominated by ion exchange interaction at low pH or moderate pH, and by surface complexation interaction at high pH. (orig.)

    A group of color tunable Sr 3 LaNa(PO 4 ) 3 F:Tb 3+ ,Eu 3+ phosphors were prepared by conventional high temperature solid state method. The phase structures, luminescence properties, fluorescence lifetimes and energy transfer were investigated in detail. Under 369nm excitation, owing to efficient energy transfer of Tb 3+ →Eu 3+ , the emission spectra both have green emission of Tb 3+ and red emission of Eu 3+ . An efficient energy transfer occur in Tb 3+ , Eu 3+ co-doped Sr 3 LaNa(PO 4 ) 3 F phosphors. The most possible mechanism of energy transfer is dipole-dipole interaction by Dexter's theoretical model.

    A group of color tunable Sr3LaNa(PO4)3F:Tb3 +,Eu3 + phosphors were prepared by conventional high temperature solid state method. The phase structures, luminescence properties, fluorescence lifetimes and energy transfer were investigated in detail. Under 369 nm excitation, owing to efficient energy transfer of Tb3 + → Eu3 +, the emission spectra both have green emission of Tb3 + and red emission of Eu3 +. An efficient energy transfer occur in Tb3 +, Eu3 + co-doped Sr3LaNa(PO4)3F phosphors. The most possible mechanism of energy transfer is dipole-dipole interaction by Dexter's theoretical model. The energy transfer of Tb3 + and Eu3 + was confirmed by the variations of emission and excitation spectra and Tb3 +/Eu3 + decay lifetimes in Sr3LaNa(PO4)3F:Tb3 +,Eu3 +. The color tone can tuned from yellowish-green through yellow and eventually to reddish-orange with fixed Tb3 + content by changing Eu3 + concentrations. The results show that the prepared Tb3 +, Eu3 + co-doped color tunable Sr3LaNa(PO4)3F phosphor can be used for white LED.

    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.

    Two crops (sunflower and upland rice) cultivated using three K-bearing minerals and KCl by Sugiyama and Ae (2000) were analyzed for rare earth elements (REEs). The two crops had been reported by them to general more available silica in soil (especially in the case of sunflower) and absorbed silica in plants (especially in the case of upland rice) than that available originally in soil. The K-bearing minerals included biotite, muscovite, and K-feldspar. The REE patterns of individual crop specimens exhibited different extents of Eu anomaly; upland rice exhibited more varying extent of Eu anomaly than sunflower. It is inferred that REEs released from the K-bearing minerals had a longer contact with soil in the case of sunflower than in the case of upland rice. By the scrutiny of the extent of the Eu anomaly, it was found that upland rice took in K and REEs from all the K-bearing minerals, including hardly-soluble feldspar. Eu anomaly can be a good proxy of sources of inorganic nutrients in plants as well as of the directness of absorption of the nutrients. When the present results are viewed from a different angle, they endorse that plant-induced weathering is equivalent to physiological action of plants. (author)

    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.

    Full Text Available Contemporary trade analysis indicates the necessity of calculating trade in value added (TiVA which is created through global value chains (GVCs. This paper aims to determine the characteristics and importance of GVC trade in the EU new member states (EU NMS with special emphasis placed on the industry level. The results demonstrate different levels of GVC participation of the EU NMS, where Hungary is the most integrated country and Croatia the least integrated. Regional GVCs exist because a huge part of value added (VA comes from EU member states, as in gross export as well as in final demand (Europe as a hub. The most important source countries are Germany and Italy and there is also evidence of geographical and historical relations between the countries. The domination of backward participation has been found in the analysis made on the industrial level, i.e. the EU NMS are highly dependent on the import of intermediates for the production and export of final products. Strong interconnections between imports of intermediate products and exports of final products have been found in the manufacture of computers, electronics and optical products; manufacture of wood, paper, printing and reproduction. This research has contributed to the scarce literature concerning GVC (TiVA in EU NMS and has opened up new possibilities for further research and analysis.

    2018-02-01

    Full Text Available Novel LiLa1−x−y(MoO42:xSm3+,yEu3+ (in short: LL1−x−yM:xSm3+,yEu3+ double molybdate red phosphors were synthesized by a solid-state reaction at as low temperature as 610 °C. The optimal doping concentration of Sm3+ in LiLa1−x(MoO42:xSm3+ (LL1−xM:xSm3+ phosphor is x = 0.05 and higher concentrations lead to emission quenching by the electric dipole—electric dipole mechanism. In the samples co-doped with Eu3+ ions, the absorption spectrum in the near ultraviolet and blue regions became broader and stronger than these of the Sm3+ single-doped samples. The efficient energy transfer from Sm3+ to Eu3+ was found and the energy transfer efficiency was calculated. Under the excitation at 403 nm, the chromaticity coordinates of LL0.95−yM:0.05Sm3+,yEu3+ approach to the NTSC standard values (0.670, 0.330 continuously with increasing Eu3+ doping concentration. The phosphor exhibits high luminous efficiency under near UV or blue light excitation and remarkable thermal stability. At 150 °C, the integrated emission intensity of the Eu3+ remained 85% of the initial intensity at room temperature and the activation energy is calculated to be 0.254 eV. The addition of the LL0.83M:0.05Sm3+,0.12Eu3+ red phosphors can improve the color purity and reduce the correlated color temperature of WLED lamps. Hence, LL1−x−yM:xSm3+,yEu3+ is a promising WLED red phosphor.

    A series of color-tunable blue–green emitting Na 2 Ca 4 (PO 4 ) 3 F:Eu 2+ ,Tb 3+ phosphors were prepared by a high temperature solid-state reaction. Their luminescence properties reveal that there is an efficient energy transfer from Eu 2+ to Tb 3+ ions via a dipole–quadrupole mechanism where Eu 2+ ions exhibit a strong excitation band in near ultraviolet (UV) region, matching well with the dominant emission band of near UV (350–420 nm) LED chips, and Eu 2+ and Tb 3+ ions can give characteristic blue and green emission light. The varied color of the phosphors from blue to green can be achieved by properly tuning the relative ratio of Eu 2+ to Tb 3+ dopant through the energy transfer from Eu 2+ to Tb 3+ ions. Thermal quenching luminescence results reveal that Na 2 Ca 4 (PO 4 ) 3 F:Eu 2+ ,Tb 3+ exhibits good thermal stability. These results demonstrate that Tb 3+ ion with low 4f–4f absorption efficiency in near UV region can play the role of an activator in narrow green-emitting phosphor through efficient energy feeding by allowing 4f–5d absorption of Eu 2+ with high oscillator strength. The present Eu 2+ –Tb 3+ codoped Na 2 Ca 4 (PO 4 ) 3 F phosphor will have potential application for the near UV white LEDs. - Highlights: ► Color-tunable blue–green Na 2 Ca 4 (PO 4 ) 3 F:Eu 2+ ,Tb 3+ phosphors were prepared. ► Eu 2+ –Tb 3+ energy transfer process and mechanism discussed. ► Thermal quenching properties of blue and green phosphors were studied.

    This paper analyses the possibilities of a strategy and all-encompassing European policy that could constitute an efficient and structured system against proliferation. This paper concentrate on actions and developments at the level of the E.U. sensu stricto, i.e. where common actions under the E.U. umbrella are set up and contribute to the efforts in non-proliferation. It does not cover all measures and mechanisms under the 'non-proliferation regime', the integrated and evolving network of unilateral, bilateral, regional, multilateral treaties and other standing-setting arrangements, which collectively provide a framework guiding the behaviour of states, international organisations, enterprises, associations and all non state actors generally active in the nuclear sector. For the purposes of this paper, the 'utilitarian and teleological' prisms are used. The 'utilitarian perspective aims to maximizing the net expectable utility for all parties affected by a decision or action knowing the that traditional utilitarianism favours the options that bring about the best consequences and aims at the 'good'. The teleological approach lies in an interpretation that favours the ultimate goals of any provision and action as well as their spirit, rather than accepting to remain in a more narrow exegetic interpretation that favours the strict letter thereof.

    Limiting the rise in the average global temperature to 2C has been the EU goal since 1996, and in December 2010 the UN recognised the need to consider a 1.5C limit. Avoiding overshooting these levels will require massive emissions reductions - in the order of 80-95% for industrialised countries, like those in the EU. The next ten years are crucial in establishing whether society will be able to make this transition, or whether temperature increase limits will be irreversibly missed. Last year, the European Union Climate Policy Tracker (EU CPT) investigated each member state's implementation of policy and legislation, and rated their progress towards a 2050 vision of deep decarbonisation using renewable energy. The uniquely developed rating scheme, modelled on appliance efficiency labels (A-G), gave an indication of how member states were doing compared to a 'low-carbon policy package'. The average score was an 'E', indicating that the level of effort needed to treble, to be on a pace to reach the 2050 vision. However, aggregating best practices across sectors and countries doubled the score - meaning that the tools are already at hand for major improvements across Europe. This report builds on last year's EU CPT by giving an update on action in member states, and an indicative trend in the rating, as well as adding a new section on EU policy. The addition of an EU section is appropriate, with the Commission having produced a roadmap on a low-carbon economy by 2050, a transport white paper, and with another roadmap for 2050 focused on energy anticipated by the end of 2011. This report seeks to answer the question of whether these and other related initiatives are sufficient to help Europe reach its low-carbon goals. When interpreting the results of this report, it is important to understand that the goal underlying the vision here is not the same as the one in the European Commission's 'low-carbon economy' roadmap

  8. Constructing post-carbon institutions: Assessing EU carbon reduction efforts through an institutional risk governance approach

    International Nuclear Information System (INIS)

    LaBelle, Michael

    2012-01-01

    This paper examines three different governance approaches the European Union (EU) and Member States (MS) are relying on to reach a low carbon economy by 2050. Current governance literature explains the operational methods of the EU's new governance approach to reduce carbon emissions. However, the literature neglects to account for the perceived risks that inhibit the roll-out of new low carbon technology. This article, through a novel approach, uses a grounded theoretical framework to reframe traditional risk literature and provides a connection to governance literature in order to assess the ability of EU governance mechanisms to reduce carbon emissions. The empirical research is based on responses from European energy stakeholders who participated in a Delphi method discussion and in semi-structured interviews; these identified three essential requirements for carbon emissions to be reduced to near zero by 2050: (1) an integrated European energy network, (2) carbon pricing and (3) demand reduction. These features correspond to institutionalized responses by the EU and MS: the Agency for the Cooperation of Energy Regulators (ACER); European Union Emission Trading Scheme (EU ETS) and energy efficiency directives and policies integrated into existing MS institutions. The theoretical and empirical findings suggest that governance by facilitation (energy efficiency) fails to induce significant investment and new policy approaches and cannot be relied on to achieve requisite reductions in demand. Governance by negotiation (ACER) and governance by hierarchy (EU ETS) do reduce risks and may encourage the necessary technological uptake. The term ‘risk governance’ is used to explain the important role governance plays in reducing risks and advancing new technology and thereby lowering carbon emissions in the energy sector. - Highlights: ► This article assesses the role of EU institutions in reducing carbon emissions by 2050. ► Empirical research is based on Delphi

    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

  20. 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.

  1. 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.

    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.

    The European Union with 15 Member States at the end of the century and with 6 more countries in the accession phase has set up certain instruments which enhance energy cooperation among them and with third countries. The major dimensions of EU energy policy presented in the White Paper are the external dimension - globalization of markets, the increasing environmental concern, the technology developments and the EU institutional responsibilities. To contribute to these, certain EU initiatives and supporting actions are undertaken through the energy and the broader co-operation programmes like THERMIE, SYNERGY, SAVE, ALTENER, PHARE, etc. The THERMIE programme supports the demonstration application and dissemination of innovative and successful energy technologies. SYNERGY is a programme for energy co-operation with third countries in energy policy and strategy implementation issues. SAVE and ALTENER concentrate on the promotion and enhancement of energy efficiency practices and use of renewable respectively. PHARE is a technical assistance programme addressed to Eastern European Countries which are in the phase of transition to market economy. There are also other initiatives like the Transeuropean Energy Network (TEN) and the activities managed by the financial institutions namely the European Bank for Reconstruction and Development (EBRD) and the European Investment Bank (EIB). All this context of programmes and initiatives is modified from period to period in order to serve the EU energy policies and the developments in the energy markets. The recent agreement which came up from the Kyoto conference has actually influenced the direction of actions towards more intensive amelioration of environmental pollution. (author)

  9. Banning banking in EU emissions trading?

    2006-01-01

    Admitting banking in emissions trading systems reduces overall compliance costs by allowing for inter-temporal flexibility: cost savings can be traded over time. However, unless individual EU Member States (MS) decide differently, the transfer of unused allowances from the period of 2005-2007 into the first commitment period under the Kyoto Protocol, i.e. 2008-2012, will be prohibited. In this paper, we first explore the implications of such a ban on banking when initial emission targets are lenient. This analysis is based on a simulation which was recently carried out in Germany with companies and with a student control group. The findings suggest that a EU-wide ban on banking would lead to efficiency losses in addition to those losses which arise from the lack of inter-temporal flexibility. Second, we use simple game-theoretic considerations to argue that, under reasonable assumptions, such a EU-wide ban on banking will be the equilibrium outcome. Thus, to avoid a possible prisoners' dilemma, MS should have co-ordinated their banking decisions

  12. DEINDUSTRIALIZATION AS A PROCESS IN THE EU

    2017-01-01

    Full Text Available Deindustrialization is a natural process in the developed countries, which takes place under the influence of external and internal factors and occurs as a result of economic growth. It is marked by the decline in the share of industry in GDP and employment with a simultaneous increased importance of the service sector. Considering the complexity of the concept, there are many theoretical approaches of deindustrialisation. In this paper the analysis of deindustrialization in the EU was conducted. The research results indicate the existence of relative deindustrialization in the EU, which is characterized by reduced share of agriculture and industry and increased share of the service sector in GDP. Also, it was found that the decrease in employment in the industry was not created as a result of a decrease in industrial production. The EU economy, including the industrial sector, is heavily influenced by the globalization process, while the process of deindustrialization is significantly impacted by the increased volume of foreign direct investment. In key strategic documents European industry is recognized as the main "engine" of the recovery of the European economy. Therefore, the highest  priority is the creation of conditions for the process of reindustrialization, i.e. the development of industry in the variable circumstances, with an emphasis on strengthening and improving the industrial foundation and implementation of new solutions based on innovation, research and new technologies.

  13. REFORM OF RULES ON EU VAT

    2018-05-01

    Full Text Available In January 2018 the EU has released two proposal designed to simplify the VAT system, specifically around reduced rates, and to reduce compliance costs of smaller businesses in respect of VAT. The EU's common rules on VAT rates do not treat Member States equally. More than 250 exemptions allow several Member States much more flexibility in setting VAT rates than others. While these derogations are due to expire once the reformed VAT system comes into place, the rates proposal will ensure that all Member States have the same flexibility and a uniform structure in which to set their own VAT rates. The second proposal is designed to make trading in other EU member states easier for smaller businesses. Currently, small businesses may benefit from generous thresholds in their state of establishment, but zero thresholds exist for nonestablished businesses, meaning higher compliance costs. The intended proposals will provide simplification measures (around invoicing, record keeping etc. for businesses with a turnover not exceeding €2 million and will allow member states to apply thresholds to non-established businesses with a turnover not exceeding €100,000.

  14. The EU's Antidumping Actions Against Chinese Products

    2014-10-01

    Full Text Available As the importance of tariffs in international trade has declined with the reduction of tariff rates under the GATT/WTO programs of multilateral trade liberalization, most governments prefer to protect domestic industries from foreign competitors through a variety of non-tariff barriers. Antidumping actions have recently become the world's biggest trade impediment due to their specific features and the antidumping activity of new users. Since China has become the major engine of world trade growth in recent years, it also has become the largest anti-dumping target in the world. However, the present world competition situation implies that world trade liberalization might arouse regional trade friction. The objective of this research is to identify whether China's WTO accession changed China's situation with regard to EU antidumping actions. The research analysis empirically proved that trade liberalization could partly affect the EU's antidumping actions against Chinese exports and the higher degree of industrial concentricity becomes a motive to increase the EU's antidumping activities against China.

  15. Differences and similarities between the EU and non-EU citizens

    2017-03-01

    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.

    How environmental regulation affects electricity players' investment decisions? Should policy makers look beyond for alternative mechanisms - such as energy efficiency, capture and storage of carbon dioxide, and incentives for renewables - to fulfill the environmental objectives set by Kyoto Protocol? This paper suggests - through a Real Option approach - how the efficacy of the EU Emission Trading Scheme on technological innovation, emissions reduction and energy price dynamics, is strongly affected by the 'hysteresis' emerging from the capital budgeting process of main utilities. As a matter of fact, long-term substitutions between coal-fired units and Combined Cycle Gas Turbine plants production only take place under quite restrictive conditions. (auth)

    Mesoporous structures are interesting materials for the incorporation of dyes, drugs, and luminescent systems, leading to materials with important multifunctionalities. In a very unique way, these guest/host materials combine the high stability of inorganic systems, new guest-structuring features, and adsorption mechanisms in their well-defined pores. This work evaluates the luminescent properties of rare earth-doped YVO 4 nanoparticles coated with a mesoporous silica shell. The use of two different synthesis methodologies allowed for particle size control. The crystalline phase emerged without further heat treatment. The mesoporous shell decreased undesirable quenching effects on YVO 4 :Eu 3+ nanoparticles and rendered them biocompatible. The materials prepared herein could have interesting applications as luminescent markers or drug release systems.

    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

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

    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.

    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.

    A series of novel red-emitting phosphors Ca9La1- x (PO4)7: xEu3+ were synthesized by high-temperature solid state reactions. The photoluminescence excitation and photoluminescence spectra of these phosphors were investigated in detail. O2--Eu3+ charge transfer band peaking at about 261 nm is dominant in the PLE spectra of Eu3+-doped Ca9La(PO4)7, indicating that the phosphors are suitable for tricolor fluorescent lamps. The phosphors also show a good absorption in near ultraviolet (around 395 nm) and blue (around 465 nm) spectral region, which indicates that it can be pumped with NUV and blue chips for white light-emitting diodes. The transition of 5D0 → 7F2 of Eu3+ in this lattice can emit bright red light. Ca9La(PO4)7 could accommodate a large amount of Eu3+ with an optimal concentration of 60 mol%. The dipole-dipole interaction between Eu3+ is the dominant mechanism for concentration quenching of Eu3+. The calculated color coordinates lie in red region ( x = 0.64, y = 0.36), which is close to Y2O3: 0.05Eu3+ ( x = 0.65, y = 0.34). The integral emission intensity of Ca9La0.4(PO4)7: 0.6Eu3+ is 1.9 times stronger than that of widely used commercial red phosphor Y2O3: 0.05Eu3+. All these results indicate that Eu3+-doped Ca9La(PO4)7 is a promising red-emitting phosphor which can be used in tricolor fluorescent lamps and white light-emitting diodes.

    New tuneable light-emitting Ca3Al8Si4O17N4:Ce(3+)/Tb(3+)/Eu(2+) oxynitride phosphors with high brightness have been prepared. When doped with trivalent cerium or divalent europium they present blue luminescence under UV excitation. The energy transfer from Ce(3+) to Tb(3+) and Ce(3+) to Eu(2+) ions is deduced from the spectral overlap between Ce(3+) emission and Tb(3+)/Eu(2+) excitation spectra. The energy-transfer efficiencies and corresponding mechanisms are discussed in detail, and the mechanisms of energy transfer from the Ce(3+) to Tb(3+) and Ce(3+) to Eu(2+) ions are demonstrated to be a dipole-quadrupole and dipole-dipole mechanism, respectively, by the Inokuti-Hirayama model. The International Commission on Illumination value of color tuneable emission as well as luminescence quantum yield (23.8-80.6%) can be tuned by controlling the content of Ce(3+), Tb(3+) and Eu(2+). All results suggest that they are suitable for UV light-emitting diode excitation.

    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

    Full Text Available On May 1, 2004 ten new states joined the EU. At the same time, budgetary cash flow mechanisms between the EU budget (as the central subject and national budgets were established. Despite the fact that all the rules are clear and known in advance - stipulated by the EU directives and regulations - there are some uncertainties, which may have an important effect on the liquidity as well as on the budgetary cash flows in new member states. The greatest problem for the liquidity of new member states’ budgets is posed by the time lags between inflows and outflows of EU funds. These lags are mainly because of delayed payments from the EU budget and problems with some member state’s absorption capacity. This article deals with the dynamics and the scale of budgetary cash flows between the Slovenian budget and the EU budget until 2006. A couple of likely scenarios are presented, which could happen in case of delayed payments of European funds. Consequently, both an unexpected state budget liquidity deficit and an additional burden arising from interest on delayed payments to the Brussels are possible for Slovenia.

    Full Text Available According to the analysis of World Bank data on the dynamics of migration indicators in Europe and Fragile State Index data the authors determine the groups of EU countries in geo-economic risk, which forms the pushing factors in the refugee flow formation. The geographic structure of refugees’ migratory flows to the EU is analyzed and the migration corridor dynamics is determined, in particular, it is found out that the overwhelming majority of refugees arrive to the EU through the Central and Eastern Mediterranean channels. In addition, It is determined that strengthening military and political instability in Africa and the Middle East, the tight policies and institutional mechanisms for crossing the EU's borders cause the increased flows of illegal migrants entering the EU in dangerous ways, in particular through the Mediterranean Sea, where a significant number of such persons, especially women and children, die. In addition, EU countries are structured by their migration policies (views on immigration, using of quantitative restrictions on immigration including highly skilled workers. As a result of the legal document study, the authors establish the system of documents identifying the institutional frameworks for the refugees’ and asylum seekers’ migratory flow management.

    The extraction behaviour of Am(III) and Eu(III) from nitric acid medium was studied in the solvent impregnated resins containing extractants such as tetra-bis(2-ethylhexyl)diglycolamide (TEHDGA) or bis-(2-ethylhexyl)phosphoric acid (HDEHP) or mixture of TEHDGA+HDEHP. The rate of extraction of Am(III) and Eu(III) from 1 M nitric acid and the effect of various parameters, such as the concentration of nitric acid in aqueous phase and concentration of TEHDGA and HDEHP in resin phase, on the distribution coefficient of Am(III) and Eu(III) was studied. The distribution coefficient of Am(III) and Eu(III) in HDEHP-impregnated resin decreased and that in TEHDGA-impregnated resin increased, with increase in the concentration of nitric acid. However, in (TEHDGA+HDEHP) - impregnated resin, synergic extraction was observed at lower nitric acid concentration and antagonism at higher nitric acid concentration. The mechanism of Am(III) and Eu(III) extraction in the combined resin was investigated by slope analysis method. The extraction of various metal ions present in the fast reactor simulated high-level liquid waste was studied. The separation factor of Am(III) over Eu(III) was studied using citrate-buffered diethylenetriaminepentaacetic acid (DTPA) solution.

  7. Adsorption behaviour and kinetics of exchange of Zn2+ and Eu3+ ions on a composite ion exchanger

    Equilibria and kinetics of exchange of both Zn2+ and Eu3+ ions on a composite ion-exchanger, cobalt hexacyanocobaltate (III) (CoHCC) incorporated in polyacrylonitrile (PAN), has been studied. The apparent capacity of CoHCC-PAN for Zn2+ and Eu3+ was determined and found to be 0.353 and 0.69 meq/g, respectively. The higher capacity for Eu3+ ions than that for Zn2+ ions is due to the higher electrostatic interaction strength of the higher charge ion with the surface. Freundlich and Langmiur adsorption isotherms were used to investigate solute (Zn2+ or Eu3+) exchange phenomenon at the liquid/solid interface. The results indicated that both Langmuir and Freundlich isotherms fit well for both Zn2+ and Eu3+. Sorption data have been also treated with the Dubinin-Radushkevich equation. The kinetics of Zn2+ or Eu3+ sorption on the composite seems to show that the reaction was proceed via two steps. The first one was fast and probably due to adsorption followed by a slow exchange reaction. In view of the data obtained on the effect of particle size and metal ion concentrations on the rate of exchange reaction, it is concluded that the mechanism for both ions was chemical control. Generally, it seems that there are two exchange sites chemically equivalent but present in pores of different sizes which lead to different degrees of dehydration of the ions sorbed on the two sites

    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.

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

    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.

  10. The Limits of Conditionality: Turkey – EU Taxation Negotiations

    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.”

    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.

    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

    Graphical abstract: Na 2 CaSiO 4 :Eu 2+ phosphor can be effectively excited by an ultraviolet and near-ultraviolet light, and produce a bright blue emission centered at 436 nm. The CIE chromaticity coordinations (x, y) of Na 2 CaSiO 4 :Eu 2+ (NSCE)/Li 2 SrSiO 4 :Eu 2+ (LSSE) vary with the molar ratio of the two constituents. When NSCE/LSSE is 1:3, the CIE chromaticity coordination is (0.332, 0.346), which is close to that of the natural sunlight (0.33, 0.33). The results indicate that Na 2 CaSiO 4 :Eu 2+ may be a promising blue phosphor for UV chip-based multi-phosphor converted white light emitting diodes. Highlights: ► Na 2 CaSiO 4 :Eu 2+ shows the blue emission with a peak at 436 nm and broad excitation band in the UV/n-UV range. ► White light with CIE coordinates (0.332, 0.346) is generated by mixing the blue phosphor with the Li 2 SrSiO 4 :Eu 2+ yellow phosphor. ► Na 2 CaSiO 4 :Eu 2+ would be a promising blue phosphor candidate for UV chip-based multi-phosphor converted white LEDs. - Abstract: A novel blue phosphor Na 2 CaSiO 4 :Eu 2+ is synthesized by a high temperature solid-state reaction, and its luminescent properties are systematically studied. Na 2 CaSiO 4 :Eu 2+ can be effectively excited by the 354 nm radiation, and create blue emission (436 nm). The emission intensity of Na 2 CaSiO 4 :Eu 2+ is influenced by the Eu 2+ doping content, and the optimal doping content is 1.5%, and the concentration quenching mechanism of Eu 2+ in Na 2 CaSiO 4 can be attributed to the multipolar interaction. The white light with CIE coordinates (0.332, 0.346) is generated by mixing the blue phosphor Na 2 CaSiO 4 :Eu 2+ with the yellow phosphor Li 2 SrSiO 4 :Eu 2+ . The results indicate that Na 2 CaSiO 4 :Eu 2+ may be a potential blue emitting phosphor for UV chip-based multi-phosphor converted white light emitting diodes

    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.

    A layerlike MOF (MIL-124, orGa2(OH)4(C9O6H4)) has been prepared and chosen as a parent compound to encapsulate Eu(3+) cations by one uncoordinated carbonyl group in its pores. The Eu(3+)-incorporated sample (Eu(3+)@MIL-124) is fully characterized, which shows excellent luminescence and good fluorescence stability in water or other organic solvents. Subsequently, we choose Eu(3+)@MIL-124 as sensitive probe for sensing metal ions, anions, and organic small molecules because of its robust framework. Studying of the luminescence properties reveals that the complex Eu(3+)@MIL-124 was developed as a highly selective and sensitive probe for detection of Fe(3+) (detection limit, 0.28 μM) and Fe(2+) ions through fluorescence quenching of Eu(3+) and MOF over other metal ions. In connection to this, a probable sensing mechanism was also discussed in this paper. In addition, when Eu(3+)@MIL-124 was immersed in the different anions solutions and organic solvents, it also shows highly selective for Cr2O7(2-)(detection limit, 0.15 μM)and acetone. Remarkably, it is the first Eu-doped MOF to exhibit an excellent ability for the detection of Fe(3+) and Fe(2+) in an aqueous environment without any structural disintegration of the framework.

    Full Text Available The studies concerning the impact of corruption on the effectiveness of governance are numerous, valorising profound approaches, based on criteria and standards related to good governance, organizational behaviour. The concepts and mechanisms specific for econometrics and statistics provide the quantitative support for qualitative analyses, substantiating public policies, in view to assure effectiveness in performance measurement. For EU Member States and acceding countries, the level of development and social organization determines specific ethical behaviours. In this context, the current paper aims a comparative economic and social evaluation of the correlations between corruption, performance and economic freedom in the states mentioned, following the various significant stages of the EU enlargement. The working hypotheses turn into consideration the following issues:# Corruption holds national specific character and the statistic, econometric or sociologic analyses reveal that it is stable during time.# The climate of economic freedom and the intensity of corruption influence powerfully the economic performance.# The EU membership, “seniority” in EU, regional context determine different attitudes and perceptions on the corruption phenomena.# For the newer EU states or the acceding countries, the strategies of integrity have mimetic character and the National Integrity Systems have structured powerful connections aimed at determining an action focused on public integrity.In the analyses achieved, the EU is approached globally, at least from statistic point of view, and the conclusions aim situations specific to the groups of states that have been or will be the beneficiaries of the EU enlargement. The quantitative analyses use both own results of the researches carried out by the authors and public results of World Bank or Heritage Foundation, as well as results of authorities responsible for national statistics.

    2015-01-01

    Full Text Available A novel phosphor, ZnB4O7:Eu3+, with urchin-like structure consisting of radially arranged high density nanorods was successfully synthesized by hydrothermal process at 150°C for 24 h. The nanorods were measured from 200 to 400 nm in diameter and several µm in length. The urchins were few µm to 40 µm in diameter. The ZnB4O7:Eu3+ phosphors were efficiently excited by ultraviolet (UV ~ 254 nm to visible light of ~ 220 to 450 nm and exhibited intense orange-red emission consisting of main peaks at 590, 615, and 695 nm due to the charge transfer in the host and f→f transitions (5D0 to 7F1,2,4 of the Eu3+ ions. Effect of the Eu3+ ions concentration on the photoluminescence (PL emission intensity was investigated and it was found that 5 at% Eu3+ is the optimum concentration. Meanwhile, the concentration quenching mechanism was discussed. The key parameters, such as temperature dependent PL and CIE values of ZnB4O7:Eu3+ phosphors, were studied. The ZnB4O7:Eu3+ phosphor exhibited good thermal stability and better absorption cross section compared to the commercial Y2O2S:Eu3+ phosphor. All these characteristics indicate that the phosphor will be a potential candidate for the UV based white LEDs.

    Spectra of excitation and emission were measured at RT and 15 K in crystals quenched (Q) of CsBr:Eu{sup 2+}, CsBr:Mn{sup 2+} and CsBr:Eu{sup 2+},Mn{sup 2+}. Emission bands at 444, 480, 520 and 570 nm with different relative intensities are generated in the samples after UV excitation. The blue band at 444 nm was ascribed with unknown clusters or aggregated centers (AC) of dipoles type Eu{sup 2+}–V{sub C}{sup −} and insulated dipole centers (IDC) like Eu{sup 2+}–O{sup 2−}. The bands at 480, 520 and 570 nm were assigned to Cs{sub 4}EuBr{sub 6} nanocrystals; AC containing MnBr{sub 4}{sup 2−} units in tetrahedral symmetry and another yet unidentified AC defect, respectively. In crystals of CsBr:Eu{sup 2+},Mn{sup 2+} the excitation and emission spectra taken at 15 K show no clear evidence of an energy transfer mechanism. Instead, the results suggest that the emission is produced by direct excitation of the ions of Eu{sup 2+} and Mn{sup 2+}. Accordingly, single- or double-doped CsBr crystals may contain the same type of defects, either AC and/or IDC. -- Highlights: • The PL consists of several overlapping bands in the entire visible region. • The emission bands were ascribed to dipoles, aggregated and nanocrystals of different nature. • No clear evidence of energy transfer, meaning Eu and Mn pairs are not formed. • The material shows potential characteristics for its use as LED to white emission.

    Full Text Available Constructivist-driven conventional wisdom posits that ideas and beliefs are pivotal to shaping foreign policy trajectories. Thus, the explanatory power ascribed to material forces falls back on ideas and cultural practices (Wendt, 1999. Whereas the case of Armenia, characterized by the co-existence of European foreign policy identity with Russia-led foreign policy preferences suggests that identity and beliefs may well be outweighed by material forces. This paper seeks to explain the evolution of how the European Union (EU and Russia have been conceptualised within the foreign policy discourse of Armenia. The study relies on the critical discourse analysis of relevant speeches and statements of Armenia’s foreign policy-makers and, particularly, on those of the President. It scrutinizes the core notions and discursive structures, employed in the Armenian foreign policy discourse for justifying the choice of the Russia-led path. It suggests that Armenia’s deviation from the identity driven path towards the EU has been broadly justified in terms of the country’s economic and, particularly, security needs, which prompted to treat Russia as an indispensable ally. Yet, a closer scrutiny of external constraints indicates that Russian coercive policy left little room for Armenia to achieve a Russian-European balance.

    A trend towards automation of scientific research has recently resulted in what has been termed "data-driven inquiry" in various disciplines, including physics and biology. The automation of many tasks has been identified as a possible future also for the humanities and the social sciences, particularly in those disciplines concerned with the analysis of text, due to the recent availability of millions of books and news articles in digital format. In the social sciences, the analysis of news media is done largely by hand and in a hypothesis-driven fashion: the scholar needs to formulate a very specific assumption about the patterns that might be in the data, and then set out to verify if they are present or not. In this study, we report what we think is the first large scale content-analysis of cross-linguistic text in the social sciences, by using various artificial intelligence techniques. We analyse 1.3 M news articles in 22 languages detecting a clear structure in the choice of stories covered by the various outlets. This is significantly affected by objective national, geographic, economic and cultural relations among outlets and countries, e.g., outlets from countries sharing strong economic ties are more likely to cover the same stories. We also show that the deviation from average content is significantly correlated with membership to the eurozone, as well as with the year of accession to the EU. While independently making a multitude of small editorial decisions, the leading media of the 27 EU countries, over a period of six months, shaped the contents of the EU mediasphere in a way that reflects its deep geographic, economic and cultural relations. Detecting these subtle signals in a statistically rigorous way would be out of the reach of traditional methods. This analysis demonstrates the power of the available methods for significant automation of media content analysis.

    2012-01-01

    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: The European Union is moving ahead with a proposal to regulate trading in carbon assets under the revised Markets in Financial Instruments Directive (MiFID). This would mean that all trading in such assets, from the European Union Emissions Trading System (EU ETS) to international carbon credits from Kyoto project-based mechanisms eligible for the EU ETS would be covered by the existing EU regulatory framework for financial markets. Allowance spot and derivative markets are set to be supervised by a single oversight authority, and the MiFID and Market Abuse Directive will apply. While this will bring benefits in terms of improved security, transparency and protections for market participants in the carbon market, future challenges for the EU ETS will involve the proper coordination of MiFID with the Auctioning Regulation, and ensuring that the ad hoc treatment of emission allowances is maintained within the MiFID legislation

    Eu2 + -doped alkali or alkali earth iodide scintillators with energy resolutions ≤3 % at 662 keV promise the excellent discrimination ability for radioactive isotopes required for homeland-security and nuclear-nonproliferation applications. To extend their applications to x-ray imaging, such as computed tomography scans, the intense afterglow which delays the response time of such materials is an obstacle that needs to be overcome. However, a clear understanding of the origin of the afterglow and feasible solutions is still lacking. In this work, we present a combined experimental and theoretical investigation of the physical insights of codoping-based defect engineering which can reduce the afterglow effectively in KCaI3:Eu2 + single-crystal scintillators. We illustrate that Sc3 + codoping greatly suppresses the afterglow, whereas Y3 + , Gd3 + , or La3 + codoping enhances the afterglow. Meanwhile, a light yield of 57 000 photons / MeV and an energy resolution of 3.4% at 662 keV can be maintained with the appropriate concentration of Sc3 + codoping, which makes the material promising for medical-imaging applications. Through our thermoluminescence techniques and density-functional-theory calculations, we are able to identify the defect structures and understand the mechanism by which codoping affects the scintillation performance of KCaI3:Eu2 + crystals. The proposed defect-engineering strategy is further validated by achieving afterglow suppression in Mg2 + codoped KCaI3:Eu2 + single crystals.

  12. Banking and Fiscal Unions in the EU: What is More Relevant?

    Full Text Available The article deals with financial system structures in the eurozone member states, linkages between banking sectors and fiscal solvency of states and EU initiatives towards improving frameworks to prevent and if necessary to deal with crises in the future. The global economic and financial crisis has revealed a close interrelation between banks problems and sovereigns in the EU. The instruments which were used by national governments in order to save systemically important banks forced the EU to revise approaches to bank supervision and establish new mechanisms for banks' restructuring. At the same time sovereign debt crises in a number of member-states, on the one hand, showed lack of an effective EU-wide system of control over a fiscal discipline and, on the other hand raised questions about lack of any system of fiscal transfers to countries hit by a negative shock. The New Banking and Fiscal unions have been designed to withshand those challenges. The author analyses problems which might be solved with the help of the new instruments established within theabove mentioned unions. At the same time far from all initiatives aimed at achieving greater fiscal consolidation might turn out to be effective when dealing with systemic problems in times of a crisis.

    The integrated European project, EU-ToxRisk, proudly sees itself as "flagship" exploring new alternative-to-animal approaches to chemical safety evaluation. It promotes mechanism-based toxicity testing and risk assessment according to the principles laid down for toxicology for the twenty-first century. The project was officially launched in January 2016 with a kickoff meeting in Egmond aan Zee, the Netherlands. Over 100 scientists representing academia and industry as well as regulatory authorities attended the inaugural meeting. The project will integrate advances in in vitro and in silico toxicology, read-across methods, and adverse outcome pathways. EU-ToxRisk will continue to make use of the case study strategy deployed in SEURAT-1, a FP7 initiative ended in December 2015. Even though the development of new non-animal methods is one target of EU-ToxRisk, the project puts special emphasis on their acceptance and implementation in regulatory contexts. This €30 million Horizon 2020 project involves 38 European partners and one from the USA. EU-ToxRisk aims at the "development of a new way of risk assessment."

    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.

  15. Mitigation and Compensation under EU Nature Conservation Law in the Flemish Region: Beyond the Deadlock for Development Projects?

    Directory of Open Access Journals (Sweden)

    Hendrik Schoukens

    2014-05-01

    Full Text Available For years, the predicament of many of the European protected habitats and species in the Flemish Region, as in many other Member States, passed relatively unnoticed. The lack of proper rules and clear implementation rules fuelled the impression amongst project developers and planning authorities that the impacts of project developments on biodiversity did not really warrant closer assessment. However, in the past ten years, strict national case law has significantly altered this view. Faced with tighter judicial scrutiny, the Habitats and Birds Directives were seen as an important obstacle to project development. Hence mitigation and compensation have now come up as novel approaches to better align spatial aspirations with the conservation of nature. In reality, mitigation was often used as a cover-up for projects that would not fit the strict requirements enshrined in the derogatory clauses. Interestingly, the Belgian Council of State showed itself quite cautious in reasserting the lax view of some planning authorities on mitigation and compensation. In reviewing the legality of several new approaches to mitigation and compensation, the Belgian Council of State, which was initially very cautious in quashing decisions that would actually jeopardise major infrastructure developments, has rendered some compelling rulings on the specific application of mitigation and compensatory measures in a spatial planning context. By letting the objectives of EU nature conservation law prevail in the face of economic interests, the recent case law of the Belgian Council of State can be seen as a remarkable example of judicial environmental activism.

    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.

    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

    2006-06-01

    Full Text Available This paper discusses the EU budget aiming at casting light on the relationship between political and economic matters and on the importance that they function as a mechanism. Somehow the budget could be compared to a barometer showing the political pressure and the level of integration inside the European Union. Discussing the structure of the budget, where the EU money come from and how are the funds distributed afterwards, and also referring to important moments in the historical development of the European Union’s budget, the paper emphasizes the same idea of financial matters strong related to the political choices. It argues also, by describing the complexity of the budgetary procedure and the importance of financial control, that the budget is an important interplay between actors, is an important balance of power trying to reach equilibrium and efficiency. The paper also reviews the main issues of the present budgetary debates, the positions taken by European actors, counting their losses and gains, and to which extent their choices are more a national concern or following the European interest, aiming at presenting the actual state of the European Union taking into account both the economic and the political integration. The budget being one of the key elements forming the structure of the big edifice, the European Union, it is of great importance when discussing budgetary matters to have in mind the present context as a whole, determined by issues like the failure of the summit for setting a new budgetary framework, or the rejection of the European Constitution by the citizens of two of its founding members. Though, it is important when discussing the budget, economical matters to put them in a political context and also to see them in the present context.

    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)

  6. The Eastern Partnership and the EU-Turkey Energy Relations

    Directory of Open Access Journals (Sweden)

    Demiryol Tolga

    2014-10-01

    Full Text Available This article discusses the prospects and challenges of energy cooperation between the European Union (EU and Turkey within the context of the Eastern Partnership (EaP. 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.

    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

    Since the last SOFT conference held in Helsinki in 2002, substantial progress has been made in the EU R and D on the divertor components. A number of activities have been completed and new ones have been launched. The present paper gives an update of the works carried out by the EU Participating Team in support of the development of the divertor, which is one of the most challenging components of the next-step ITER machine. The following topics are covered: (1) the further development and consolidation of suitable technologies for the production of high heat-flux components, which culminated with the successful manufacturing and testing of a full-scale vertical target prototype; (2) the completion of the post-irradiation testing of divertor mock-ups and samples; (3) the preparation for the hydraulic and assembly tests of a complete set of full-scale divertor components; (4) the on-going R and D on the definition of workable acceptance criteria for the procurement of ITER high heat-flux components; (5) the activities in support of the divertor design

    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.

    An orange emitting long persistent phosphor LiSr 4 (BO 3 ) 3 :Eu 2+ was prepared successfully using a conventional solid state reaction method. The luminescent and persistent luminescence properties were studied using fluorescence spectra, decay curves, persistent luminescence spectra and thermoluminescence (TL) glow curves. The effects on the fluorescence and persistent luminescence properties by the dosage of Li 2 CO 3 were explored. The relationship between the Eu 2+ contents and persistent luminescence properties were studied. The optimal doping concentration of Eu 2+ was experimentally to be 1 mol%. The detailed processes and a possible mechanism were also discussed. - Highlights: • Li 2 CO 3 plays a critical role in producing persistent luminescence. • 40 % excess of Li 2 CO 3 makes the largest enhancement on persistent luminescence. • The optimal doping concentration of Eu 2+ was experimentally to be 1mol %. • Possible mechanism for persistent luminescence was discussed.

    Eu{sup 3+}-doped NaGd(WO{sub 4}){sub 2} nanophosphors were synthesized via a facile one-step hydrothermal method without any surfactants or a further heat treatment. X-ray powder diffraction (XRD), scanning electron microscope (SEM), fourier transform infrared spectroscopy (FT-IR), the photoluminescence (PL) excitation and emission spectra, and decay curves were used to characterize NaGd(WO{sub 4}){sub 2}:Eu{sup 3+} phosphors. The results show that the Eu{sup 3+}-concentration has little influence on the structure and morphology of the as-synthesized samples. However, pH value plays a vital role on the structure and morphology of NaGd(WO{sub 4}){sub 2}. The well-crystallized sheet-like NaGd(WO{sub 4}){sub 2} phosphors can be obtained only at pH = 5–7. On the basis of the time-dependent synthesis, a possible growth mechanism of sheet-like architectures is proposed. The luminescence properties of NaGd{sub 1-x}Eu{sub x}(WO{sub 4}){sub 2} (0 ≤ x ≤ 1) are investigated. It is found that the charge transfer band of Eu{sup 3+} shifts to lower energy and broadens with increasing the Eu{sup 3+}-concentration. - Highlights: • NaGd(WO{sub 4}){sub 2}:Eu{sup 3+} nanosheets were synthesized by facile one-step hydrothermal method. • Luminescence properties of NaGd(WO{sub 4}){sub 2}:Eu{sup 3+} phosphor were firstly reported. • The CT band of Eu{sup 3+} depends strongly on Eu{sup 3+}-concentrations.

    A series of novel color-tunable Ba3Y4O9:Bi(3+),Eu(3+) phosphors were prepared for the first time via the high-temperature solid-state reaction route. The effect of Bi(3+) concentration on the emission intensity of Ba3Y4O9:Bi(3+) was investigated. The emission spectra of the Ba3Y4O9:Bi(3+),Eu(3+) phosphors present both a greenish yellow band of Bi(3+) emission centered at 523 nm, and many characteristic emission lines of Eu(3+), derived from the allowed (3)P1-(1)S0 transition of the Bi(3+) ion and the (5)D0-(7)FJ transition of the Eu(3+) ion, respectively. The energy transfer phenomenon from Bi(3+) to Eu(3+) ions is observed under UV excitation in Bi(3+), Eu(3+) co-doped Ba3Y4O9 phosphors, and their transfer mechanism is demonstrated to be a resonant type via dipole-quadrupole interaction. The critical distance between Bi(3+) and Eu(3+) for the energy transfer effect was calculated via the concentration quenching and spectral overlap methods. Results show that color tuning from greenish yellow to orange red can be realized by adjusting the mole ratio of Bi(3+) and Eu(3+) concentrations based on the principle of energy transfer. Moreover, temperature-dependent PL properties, CIE chromaticity coordinates and quantum yields of Ba3Y4O9:Bi(3+),Eu(3+) phosphors were also supplied. It is illustrated that the as-prepared Ba3Y4O9:Bi(3+),Eu(3+) phosphors can be potential candidates for color-tunable phosphors applied in UV-pumped LEDs.

    Full Text Available The concept of national and regional development strategies for small and medium-sized enterprises (SMEs are studied for a long time, as small and medium businesses are the foundation of the economy and the basis for effective country functioning. The business development program of the European Union countries is particularly interesting because there are several levels that correspond to each other and give full effect on the SMEs development. The EU standards are higher than in non-EU countries; therefore, it is worth considering legislative documents, as well as statistics showing the indicators of openness and access to the development of small and medium-sized enterprises (SMEs. The complexity and comparative novelty of studying such a problem in Ukraine led to the need to explore sources of information in the original language due to the lack of information in Ukrainian or Russian. All these suggest that the problem of creating strategies at the national and regional level is more relevant and important to study in the West that demonstrates the current state. The subject of the study is to analyse the effectiveness of implementing strategies for the development of small and medium-sized enterprises as well as the impact of national and regional policies on their functioning and development in the European Union countries. Methodology. The authors highlighted the peculiarities and main features of the development strategies implementation for small and medium-sized enterprises in the EU countries through a comparative analysis of the legislative framework, statistical and other data that help assess the performance and effectiveness of the implemented strategies. The content analysis helps to identify peculiarities of the implemented strategies in quantitative and qualitative forms. The thorough analysis using the above-mentioned methods allowed doing a qualitative study of national and regional strategies in the context of the

    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.

    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.

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

    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 .

    Citizens’ media use can be an important predictor of attitudes towards the European Union; those attitudes, in turn, can affect EU-related vote decisions. Elementary changes in the media environment and the increasing pressure on the EU in recent referendums may therefore be connected (e.g. Denmark...... in a referendum. Using a two-wave survey design (n=675), the study investigates if political social media use reinforces existing attitudes towards the EU. Subsequently, positive and negative polarization tendencies are connected to the ‘yes or no’ vote of Danish citizens in the 2015 EU referendum. The study...

    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.

    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.

    Research on health worker migration in the Irish context has categorized migrant health workers by country or region of training (for example, non-EU nurses or doctors) or recruitment mechanism (for example, actively recruited nurses). This paper applies a new typology of health worker migrants - livelihood, career-oriented, backpacker, commuter, undocumented and returner migrants (European Observatory on Health Systems and Policies and WHO, vol. 2:129-152, 2014) - to the experiences of non-EU migrant doctors in Ireland and tests its utility for understanding health worker migration internationally. The paper draws on quantitative survey (N = 366) and qualitative interview (N = 37) data collected from non-EU migrant doctors in Ireland between 2011 and 2013. Categorizing non-EU migrant doctors in Ireland according to the typology (European Observatory on Health Systems and Policies and WHO, vol. 2:129-152, 2014) offers insight into their differing motivations, particularly on arrival. Findings suggest that the career-oriented migrant is the most common type of doctor among non-EU migrant doctor respondents, accounting for 60 % (N = 220) of quantitative and 54 % (N = 20) of qualitative respondents. The authors propose a modification to the typology via the addition of two additional categories - the family migrant and the safety and security migrant. Employing a typology of health worker migration can facilitate a more comprehensive understanding of the migrant medical workforce, a necessary prerequisite for the development of useful policy tools (European Observatory on Health Systems and Policies and WHO, vol. 2:129-152, 2014). The findings indicate that there is some fluidity between categories, as health worker motivations change over time. This indicates the potential for policy levers to influence migrant health worker decision-making, if they are sufficiently "tuned in" to migrant health worker motivation.

    The crystal structure, electronic structure and optical properties of BaSi{sub 2}O{sub 2}N{sub 2}:Eu{sup 2+} with varying Eu doping concentrations are computed by the density functional theory (DFT) and compared with experimental results. The results show that the lattice parameters of primitive cells of Ba{sub 1−x}Si{sub 2}O{sub 2}N{sub 2}:Eu{sub x} become smaller and Eu–N bond length shortens as Eu concentration increases. The band structure of Ba{sub 1−x}Si{sub 2}O{sub 2}N{sub 2}:Eu{sub x} exhibits a direct optical band gap and it's propitious to luminescence. The energy differences from the lowest Eu 5d state to the lowest Eu 4f state decrease with increasing Eu concentrations. The analysis of simulative absorption spectra indicates that the electron transition from Eu 4f states to 5d states of both Eu and Ba atoms contributes to the absorption of Ba{sub 1−x}Si{sub 2}O{sub 2}N{sub 2}:Eu{sub x}. Under the coupling effect between Eu and Ba, Ba in BaSi{sub 2}O{sub 2}N{sub 2} exhibits longer wavelength absorption and increases absorption efficiency. The emission wavelength is deduced by measuring energy differences from the lowest Eu 5d state to the lowest Eu 4f state, and the result is in good agreement with experimental value within experimental Eu{sup 2+} doping range. - Graphical abstract: The structure and optical property of BaSi{sub 2}O{sub 2}N{sub 2}:Eu{sup 2+} are computed by DFT and its absorption mechanism is analysed. Results show that absorption peak α is from the host lattice absorption. The absorption peaks β, γ and δ are from Eu 4f to Eu 5d and Ba 6s 5d states. The absorption is attributed to the coupling effect of Eu and Ba atom. - Highlights: • The crystal, electronic structure and optical properties of BaSi{sub 2}O{sub 2}N{sub 2}:Eu{sup 2+} are computed by DFT. • The lattice parameters of primitive cells reduces and Eu–N bond length shortens as Eu{sup 2+} increases. • The energy gap from Eu 5d state to Eu 4f state

    The electron cyclotron (EC) heating and current drive (H (and) CD) system of ITER will deliver 20 MW/CW in the plasma at 170 GHz for H (and) CD in addition to 2.5 MW/3 s at 120 GHz for plasma start-up. The EC system is composed of power supplies (PS), up to 24 H (and) CD gyrotrons (1 to 2 MW tubes), 3 start-up gyrotrons (1 MW tubes), 24 transmission lines and two sets of launching antennas: equatorial (EL) and upper (UL) launchers. Under the present ITER procurement package the EU is responsible for one third of the H (and) CD 170 GHz gyrotrons, all PSs associated with the H (and) CD system, and the whole set (4) of upper launchers. In all areas of participation, the EU EC partnership (coordinated by the European Fusion Development Association - EFDA) aims toward advancing the technology of each of these subsystems. For example, procurement of Pulse Step Modulator (PSM) HVPS is under consideration, which might have equivalent costs to the present ITER design (thyristor HVPS and HV series switch), but with an increased flexibility in operation and variation in the EC power waveform. The EU is at the forefront in gyrotron research and is developing a 2 MW CW 170 GHz coaxial cavity gyrotron offering an increase in output power while maintaining moderate power densities in the gyrotron cavity and collector. THALES R in collaboration with its EFDA partners (FZK, CRPP, TEKES) is manufacturing a series of prototype tubes in three phases of typically 1 s, 100 s and then CW pulse capacity (∼ 20 10 ). A 2 MW, CW gyrotron test facility is being built at CRPP that will be used to develop the 2 MW coaxial tube, in addition to testing various components required by the EC system. EFDA has undertaken a parallel development of two launcher options: front (FS) and remote (RS) steering, with the aim of providing an optimum launcher for ITER weighing EC physics aspects and operation reliability. The FS launcher (ITER reference design) offers a significant enhancement in physics

    In phosphor area today top priority is the replacement of the high performance but very expensive rare earth activated phosphors with cheaper materials. This essentially means replacing the rare earth ions with transition metal ions or post transition ions. Now a day's phosphors are used in various fields. After World War II, the advances in the optical spectroscopy of solids, especially those of transition metals ions help to evolve research on phosphor and solid state luminescence. In 1960 efficient rare earth activated phosphors were developed for use in color TV (Tb 3+ green, Eu 3+ red, and Dy 3+ yellow). In 1970 tricolor lamp was introduced blue emission from Ce 3+ + Tb 3+ pair was used in tricolor lamps. At present combination of halo phosphor and tri-band phosphor blend is used in many lamp as a compromise between performance, phosphor cost and the lamp making Cost. Thermo luminescence of 0.5 Gy X-ray irradiated BAM.Eu has been studied. The irradiated phosphor has been studied for its TL dosimetric properties one week after irradiation and after 100 weeks of storage. Interesting TL results are reported in the present paper. Heating rate used in the present experiment is 6.6 deg C/Sec. The following two figures are on TL recorded 100 weeks after irradiation and TL recorded after 235 weeks of storage. Before storage for 100 weeks the TL glow curve with a hump around 180 deg C followed by a peak at 273 deg C. After storage for 100 weeks the TL pattern changes entirely. i.e. the composite TL peak structure emerged as two well resolved peaks and with slightly higher TL peak temperatures at 215 deg C and 300 deg C. Normally after storage for 100 weeks the peak at 190 deg C reduces in its intensity or disappears in some cases, instead of that the peak appears at 215 deg C as well resolved peak and its intensity is almost comparable to that of 300 deg C peak. Since the TL phenomenon observed is interesting the two well resolved, isolated, high intensity peaks

    Several Frankia strains have been shown to be copper-tolerant. The mechanism of their copper tolerance was investigated for Frankia sp. strain EuI1c. Copper binding was shown by binding studies. Unusual globular structures were observed on the surface of the bacterium. These globular structures were composed of aggregates containing many relatively smaller "leaf-like" structures. Scanning electron microscopy with energy-dispersive X-ray (SEM-EDAX) analysis of these structures indicated elevated copper and phosphate levels compared to the control cells. Fourier transform infrared spectroscopy (FTIR) analysis indicated an increase in extracellular phosphate on the cell surface of copper-stressed cells. Bioinformatics' analysis of the Frankia sp. strain EuI1c genome revealed five potential cop genes: copA, copZ, copC, copCD, and copD. Experiments with Frankia sp. strain EuI1c using qRT-PCR indicated an increase in messenger RNA (mRNA) levels of the five cop genes upon Cu(2+) stress. After 5 days of Cu(2+) stress, the copA, copZ, copC, copCD, and copD mRNA levels increased 25-, 8-, 18-, 18-, and 25-fold, respectively. The protein profile of Cu(2+)-stressed Frankia sp. strain EuI1c cells revealed the upregulation of a 36.7 kDa protein that was identified as FraEuI1c_1092 (sulfate-binding periplasmic transport protein). Homologues of this gene were only present in the genomes of the Cu(2+)-resistant Frankia strains (EuI1c, DC12, and CN3). These data indicate that copper tolerance by Frankia sp. strain EuI1c involved the binding of copper to the cell surface and transport proteins.

  14. Selective separation of Eu3+ using polymer-enhanced ultrafiltration

    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

    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.
