    Terahertz (THz) response of a chemical vapor deposited graphene on a quartz substrate has been investigated by using an ultrafast optical-pump THz-probe spectroscopy. Without photoexcitation, the frequency-dependence optical conductivity shows a strong carrier response owing to the intrinsically doped graphene. Upon photoexcitation, an enhancement in THz transmission is observed and the transmission increases nonlinearly with the increase of pump power, which is rooted in a reduction of intrinsic conductivity arising from the strong enhancement of carrier scattering rather than THz emission occurrence. The modulation depth of 18.8% was experimentally achieved, which is more than four times greater than that of the previous reported. The photoinduced response here highlights the variety of response possible in graphene depending on the sample quality, carrier mobility and doping level. The graphene provides promising applications in high-performance THz modulators and THz photoelectric devices.

    We studied the association of Eu(III) with Gram-negative bacteria, Alcaligenes faecalis, Shewanella putrefaciens, and Paracoccus denitrificans by a batch method and time-resolved laser-induced fluorescence spectroscopy (TRLFS). The kinetics study showed that the Eu(III) adsorption on the bacteria rapidly proceeded. The Eu(III) adsorption on A. faecalis and P. denitrificans at pHs 3, 4, and 5, and that on S.putrefaciens at pHs 4 and 5 reached a maximum within 5 minutes after contact. For P. denitrificans, the percent adsorption of Eu(III) decreased after the maximum percent adsorption was attained, which suggests the existence of exudates with an affinity with Eu(III). TRLFS showed that the coordination of Eu(III) on these bacteria is multidentate through an inner-spherical process. The ligand field of Eu(III) on P. denitrificans was as strong as the ones observed for halophilic microorganisms, while that of A. faecalis and S. putrefaciens was the typical one observed for non-halophilic microorganisms. The coordination environment of Eu(III) on the bacteria differed from each other, though they are categorized as Gram-negative bacteria with the similar cell wall components. (author)

    1999-11-01

    Negative ion plasmas (NIPs) are charge-neutral plasmas in which the negative charge is dominated by negative ions rather than electrons. They are found in laser discharges, combustion products, semiconductor manufacturing processes, stellar atmospheres, pulsar magnetospheres, and the Earth's ionosphere, both naturally and man-made. They often display signatures of strong turbulence^1. Development of a novel, compact, unmagnetized alkali halide (MX) NIP source will be discussed, it incorporating a ohmically-heated incandescent (2500K) tantulum solenoid (3cm dia, 15 cm long) with heat shields. The solenoid ionizes the MX vapor and confines contaminant electrons, allowing a very dry (electron-free) source. Plasma densities of 10^10 cm-3 and positive to negative ion mass ratios of 1 Fusion 4, 91 (1978).

    We study impact of inertia on directed transport of a Brownian particle under non-equilibrium conditions: the particle moves in a one-dimensional periodic and symmetric potential, is driven by both an unbiased time-periodic force and a constant force, and is coupled to a thermostat of temperature T. Within selected parameter regimes this system exhibits negative mobility, which means that the particle moves in the direction opposite to the direction of the constant force. It is known that in such a setup the inertial term is essential for the emergence of negative mobility and it cannot be detected in the limiting case of overdamped dynamics. We analyse inertial effects and show that negative mobility can be observed even in the strong damping regime. We determine the optimal dimensionless mass for the presence of negative mobility and reveal three mechanisms standing behind this anomaly: deterministic chaotic, thermal noise induced and deterministic non-chaotic. The last origin has never been reported. It may provide guidance to the possibility of observation of negative mobility for strongly damped dynamics which is of fundamental importance from the point of view of biological systems, all of which in situ operate in fluctuating environments.

    Diffusion experiments in compacted FEBEX bentonite were performed with strongly sorbing radionuclides, 60 Co and 152 Eu. Diffusion experiments with these radionuclides present several difficulties: first of all these tests are very time consuming because of the high sorption on the clays, secondly these elements not only present high sorption onto clays but also on diffusion cells, tubing, filters and reservoirs, typically used in the classical through-diffusion or in-diffusion methods, which makes difficult the interpretation of the results. In this study, the experiments were performed using the instantaneous planar source method, where a paper filter tagged with a tracer is placed between two tablets of compacted bentonite. The apparent diffusion coefficient (D a ) is obtained analysing the tracer concentration profile in the samples at the end of the experiment, both with an analytical and a numerical approach. The ranges of D a values obtained from these experiments in the FEBEX clay compacted at 1.65 g/cm 3 are (0.5-2.3) x 10 -13 m 2 /s for Co and (0.8-2.5) x 10 -14 m 2 /s for Eu. Results showed that the analytical solution is able to fit reasonably well the Eu concentration profiles, whereas Co concentration profiles show a different behavior, not straightforward to explain, which was also analyzed by numerical methods.

    Document available in extended abstract form only. Compacted bentonite is used as an engineered barrier in high-level radioactive waste (HLRW) repositories because is a swelling clay of very low permeability and high sorption capability for many solutes. The transport of radionuclides through compacted bentonite is a diffusion-controlled process retarded by sorption. Performance assessment calculations of a repository need diffusion coefficients data of relevant radionuclides. Several studies on diffusion behaviour of neutral, anionic and weakly sorbing elements on clay exist while very few studies are available for moderately sorbing elements, and almost no studies for Eu, a highly sorbing element are reported. In this study, diffusion experiments with strongly sorbing radionuclides, as 60 Co and 152 Eu, have been performed through compacted FEBEX bentonite. Diffusion essays with these strongly sorbing radionuclides are not straightforward to carry out because they are very time consuming essays, but also because sorption on the diffusion cells, tubing, filters and reservoirs, typically used in the classical through-diffusion or in-diffusion methods make hard the interpretation of the experimental results and the calculation of the diffusion coefficients. FEBEX bentonite was selected as Spanish reference buffer materials, and used in many national and international projects. The clay comes from the Cortijo de Archidona deposit (Almeria, Spain), and has a smectite content greater than 90% (93 ± 2%), with quartz (2 ± 1%), plagioclase (3 ± 1%), cristobalite (2 ± 1%), potassic feldspar, calcite, and trydimite as accessory minerals. The specific weight of the FEBEX bentonite is 2.7 g/cm 3 . Diffusion experiments were performed using the instantaneous plane source method. In this setup, a paper filter tagged with a tracer is introduced between two compacted tablets, avoiding contact between the tracer and the experimental vessels. The tracer can diffuse into both

  10. Debunking vaccination myths: strong risk negations can increase perceived vaccination risks.

    Betsch, Cornelia; Sachse, Katharina

    2013-02-01

    Information about risks is often contradictory, especially in the health domain. A vast amount of bizarre information on vaccine-adverse events (VAE) can be found on the Internet; most are posted by antivaccination activists. Several actors in the health sector struggle against these statements by negating claimed risks with scientific explanations. The goal of the present work is to find optimal ways of negating risk to decrease risk perceptions. In two online experiments, we varied the extremity of risk negations and their source. Perception of the probability of VAE, their expected severity (both variables serve as indicators of perceived risk), and vaccination intentions. Paradoxically, messages strongly indicating that there is "no risk" led to a higher perceived vaccination risk than weak negations. This finding extends previous work on the negativity bias, which has shown that information stating the presence of risk decreases risk perceptions, while information negating the existence of risk increases such perceptions. Several moderators were also tested; however, the effect occurred independently of the number of negations, recipient involvement, and attitude. Solely the credibility of the information source interacted with the extremity of risk negation: For credible sources (governmental institutions), strong and weak risk negations lead to similar perceived risk, while for less credible sources (pharmaceutical industries) weak negations lead to less perceived risk than strong negations. Optimal risk negation may profit from moderate rather than extreme formulations as a source's trustworthiness can vary.

  11. Strong negative self regulation of Prokaryotic transcription factors increases the intrinsic noise of protein expression

    2008-01-01

    Full Text Available Abstract Background Many prokaryotic transcription factors repress their own transcription. It is often asserted that such regulation enables a cell to homeostatically maintain protein abundance. We explore the role of negative self regulation of transcription in regulating the variability of protein abundance using a variety of stochastic modeling techniques. Results We undertake a novel analysis of a classic model for negative self regulation. We demonstrate that, with standard approximations, protein variance relative to its mean should be independent of repressor strength in a physiological range. Consequently, in that range, the coefficient of variation would increase with repressor strength. However, stochastic computer simulations demonstrate that there is a greater increase in noise associated with strong repressors than predicted by theory. The discrepancies between the mathematical analysis and computer simulations arise because with strong repressors the approximation that leads to Michaelis-Menten-like hyperbolic repression terms ceases to be valid. Because we observe that strong negative feedback increases variability and so is unlikely to be a mechanism for noise control, we suggest instead that negative feedback is evolutionarily favoured because it allows the cell to minimize mRNA usage. To test this, we used in silico evolution to demonstrate that while negative feedback can achieve only a modest improvement in protein noise reduction compared with the unregulated system, it can achieve good improvement in protein response times and very substantial improvement in reducing mRNA levels. Conclusion Strong negative self regulation of transcription may not always be a mechanism for homeostatic control of protein abundance, but instead might be evolutionarily favoured as a mechanism to limit the use of mRNA. The use of hyperbolic terms derived from quasi-steady-state approximation should also be avoided in the analysis of stochastic

    The synthesis and photoluminescence properties of trivalent europium doped lithium titanate (Eu{sup 3+}:Li{sub 4}Ti{sub 5}O{sub 12}) with different Eu{sup 3+} concentrations (0.1 mol%, 0.3 mol%, 1.0 mol%, 3.0 mol%) are reported and analyzed as a phosphor. Europium (III) nitrate (Eu(NO{sub 3}){sub 3}) was employed as Eu{sup 3+} source, while lithium acetate dihydrate (CH{sub 3}COOLi·2H{sub 2}O) and titanium n-butoxide (Ti(OC{sub 4}H{sub 9}){sub 4}) were adopted as raw materials to synthesize the host lithium titanate with a Li:Ti stoichiometry of 4.5:1. Phase identification was performed using X-ray diffraction (XRD), and morphology was examined using scanning electron microscopy (SEM). Eu{sup 3+}:Li{sub 4}Ti{sub 5}O{sub 12} powders showed strong red emission at 612 nm, corresponding to the {sup 5}D{sub 0}–{sup 7}F{sub 2} transition, with the strongest excitation peak observed in the blue light region at 464 nm. Decay time analyses revealed relatively short lifetimes accompanying typical exponential decay rates. The effect of Eu{sup 3+} concentration (0.1 mol%, 0.3 mol%, 1.0 mol%, 3.0 mol%) on photoluminescence intensity and decay time was explored, and is reported here. It was determined that the CIE color coordinates (0.66, 0.34) of the doped Li{sub 4}Ti{sub 5}O{sub 12} powders were independent of Eu{sup 3+} concentration, and that the coordinates are very similar to the ideal red chromaticity (0.67, 0.33) designated by the National Television Standard Committee (NTSC) system.

  14. Achieving a strongly negative scattering asymmetry factor in random media composed of dual-dipolar particles

    Understanding radiative transfer in random media like micro- or nanoporous and particulate materials, allows people to manipulate the scattering and absorption of radiation, as well as opens new possibilities in applications such as imaging through turbid media, photovoltaics, and radiative cooling. A strong-backscattering phase function, i.e., a negative scattering asymmetry parameter g , is of great interest, which can possibly lead to unusual radiative transport phenomena, for instance, Anderson localization of light. Here we demonstrate that by utilizing the structural correlations and second Kerker condition for a disordered medium composed of randomly distributed silicon nanoparticles, a strongly negative scattering asymmetry factor (g ˜-0.5 ) for multiple light scattering can be realized in the near infrared. Based on the multipole expansion of Foldy-Lax equations and quasicrystalline approximation (QCA), we have rigorously derived analytical expressions for the effective propagation constant and scattering phase function for a random system containing spherical particles, by taking the effect of structural correlations into account. We show that as the concentration of scattering particles rises, the backscattering is also enhanced. Moreover, in this circumstance, the transport mean free path is largely reduced and even becomes smaller than that predicted by independent scattering approximation. We further explore the dependent scattering effects, including the modification of electric and magnetic dipole excitations and far-field interference effect, both induced and influenced by the structural correlations, for volume fraction of particles up to fv˜0.25 . Our results have profound implications in harnessing micro- or nanoscale radiative transfer through random media.

    EuTiO3 exhibits strong magneto-electric coupling at the onset of antiferromagnetic order below TN = 5.7 K. The dielectric permittivity drops at TN by 7% and recovers to normal values with increasing magnetic field. This effect is shown to stem from tiny lattice effects as seen in magnetostriction data which directly affect the soft optic mode and its polarizability coordinate. By combining experimental results with theory we show that marginal changes in the lattice parameter of the order of 0.01% have a more than 1000% effect on the transverse optic soft mode of ETO and thus easily induce a ferroelectric instability.

    We consider a two-dimensional magnetic tunnel junction of the FM/I/QW(FM+SO)/I/N structure, where FM, I and QW(FM+SO) stand for a ferromagnet, an insulator and a quantum wire with both magnetic ordering and Rashba spin-orbit (SOC), respectively. The tunneling magneto-resistance (TMR) exhibits strong anisotropy and switches sign as the polarization direction varies relative to the quantum-wire axis, due to interplay among the one-dimensionality, the magnetic ordering, and the strong SOC of the quantum wire.

    Numerous studies have yielded small, negative correlations between measures of paranormal and "traditional religious beliefs". This may partly reflect opinions of Christians in the samples who take biblical sanctions against many "paranormal" activities seriously. To test this, 391 college students (270 women and 121 men) rated their beliefs in various paranormal phenomena and were classified as Believers, Nominal Believers, and Nonbelievers on the strength of their self-rated commitment to key biblical (particularly Protestant) doctrines. As predicted, Believers were significantly less likely than Nominal Believers or Nonbelievers to endorse reincarnation, contact with the dead, UFOs, telepathy, prophecy, psychokinesis, or healing, while the beliefs of Nominal Believers were similar to those of Nonbelievers. Substantial percentages of Nominal and Nonbelievers (30-50%) indicated at least moderate acceptance of the paranormal phenomena surveyed.

    The nuclear liquid drop model is applied to describe some basic properties of a negative hydrogen ion in the strong electric field of a laser. The equilibrium ionic size, energy and polarizability of the ion are calculated. Collective modes of the dipole oscillations are considered. A barrier which arises in a strong electric field is studied. The barrier vanishes at some large value of the electric field, which is defined as a critical value. The dependence of the critical field on frequency is studied. At frequencies {omega}{>=}({omega}{sub d}/2{sup 1/2}) ({omega}{sub d} is the frequency of the dipole oscillations of the electronic cloud relative to the nucleus) the barrier remains for any field. At high frequencies a 'stripping' mechanism for instability arises. At the resonant frequency a rather low amplitude of the electric field causes the 'stripping' instability. (author)

  20. Can we bet on negative emissions to achieve the 2°C target even under strong carbon cycle feedbacks?

    Negative emission technologies such as Bioenergy with Carbon dioxide Capture and Storage (BioCCS) play an ever more crucial role in meeting the 2°C stabilization target. However, such technologies are currently at their infancy and their future penetrations may fall short of the scale required to stabilize the warming. Furthermore, the overshoot in the mid-century prior to a full realization of negative emissions would give rise to a risk because such a temporal but excessive warming above 2°C might amplify itself by strengthening climate-carbon cycle feedbacks. It has not been extensively assessed yet how carbon cycle feedbacks might play out during the overshoot in the context of negative emissions. This study explores how 2°C stabilization pathways, in particular those which undergo overshoot, can be influenced by carbon cycle feedbacks and asks their climatic and economic consequences. We compute 2°C stabilization emissions scenarios under a cost-effectiveness principle, in which the total abatement costs are minimized such that the global warming is capped at 2°C. We employ a reduced-complexity model, the Aggregated Carbon Cycle, Atmospheric Chemistry, and Climate model (ACC2), which comprises a box model of the global carbon cycle, simple parameterizations of the atmospheric chemistry, and a land-ocean energy balance model. The total abatement costs are estimated from the marginal abatement cost functions for CO2, CH4, N2O, and BC.Our preliminary results show that, if carbon cycle feedbacks turn out to be stronger than what is known today, it would incur substantial abatement costs to keep up with the 2°C stabilization goal. Our results also suggest that it would be less expensive in the long run to plan for a 2°C stabilization pathway by considering strong carbon cycle feedbacks because it would cost more if we correct the emission pathway in the mid-century to adjust for unexpectedly large carbon cycle feedbacks during overshoot. Furthermore, our

    To study the cellular mechanism of the tendon repair process, we used a mouse Achilles tendon injury model to focus on the cells recruited to the injured site. The cells isolated from injured tendon 1 week after the surgery and uninjured tendons contained the connective tissue progenitor populations as determined by colony-forming capacity, cell surface markers, and multipotency. When the injured tendon-derived progenitor cells (inTPCs) were transplanted into injured Achilles tendons, they were not only integrated in the regenerating area expressing tenogenic phenotype but also trans-differentiated into chondrogenic cells in the degenerative lesion that underwent ectopic endochondral ossification. Surprisingly, the micromass culture of the inTPCs rapidly underwent chondrogenic differentiation even in the absence of exogenous bone morphogenetic proteins or TGFβs. The cells isolated from human ruptured tendon tissues also showed connective tissue progenitor properties and exhibited stronger chondrogenic ability than bone marrow stromal cells. The mouse inTPCs contained two subpopulations one positive and one negative for CD105, a coreceptor of the TGFβ superfamily. The CD105-negative cells showed superior chondrogenic potential in vitro and induced larger chondroid degenerative lesions in mice as compared to the CD105-positive cells. These findings indicate that tendon progenitor cells are recruited to the injured site of tendons and have a strong chondrogenic potential and that the CD105-negative population of these cells would be the cause for chondroid degeneration in injured tendons. The newly identified cells recruited to the injured tendon may provide novel targets to develop therapeutic strategies to facilitate tendon repair. © 2014 AlphaMed Press.

    A series of Na3Mo12PO40:xEu3+ phosphors have been successfully synthesized by a solid-state method, and characterized by powder x-ray diffraction (PXRD). The PXRD results confirm that the samples have crystal phases of Na3Mo12PO40. For PL spectra of Na3Mo12PO40:2.0Eu3+ excited by 394 and 465 nm, R (R is the peak area ratio of 5D0  →  7F2 to 5D0  →  7F1) is only 1.46 with an excitation of 394 nm, but increases to 3.03 with an excitation of 465 nm. Furthermore, a new enhancement of electric dipole transition is observed. Emission spectrum (PL) intensity at 617 nm excited by 465 nm is 1.95 times as high as the excitation spectrum (PLE) intensity at 465 nm. Thus, cooperative energy transfers from the magnetic dipole (MD) Eu3+ center to the electric dipole (ED) Eu3+ center when excited by 465 nm is demonstrated for the new fluorescent behavior.

    Full Text Available Mental imagery, seeing with the mind’s eyes, can induce stronger positive as well as negative affect compared to verbal processing. Given this emotion-amplifying effect, it appears likely that mental images play an important role in affective disorders. According to the subcomponents model of depression, depressed mood is maintained by both negative imagery (which amplifies negative mood and less efficient positive imagery processes. Empirical research on the link between mental imagery and affect in clinical depression, however, is still sparse. This study aimed at testing the role of mental imagery in depression, using a modified version of the Affect Misattribution Procedure (AMP and the Self-Assessment Manikin (SAM to assess implicit (AMP and explicit (SAM affect elicited by mental images, pictures, and verbal processing in clinically depressed participants (n = 32 compared to healthy controls (n = 32. In individuals with a depressive disorder, compared to healthy controls, negative mental images induced stronger negative affect in the explicit as well as implicit measure. Negative mental imagery did not, however, elicit greater increases in explicitly and implicitly assessed negative affect compared to other processing modalities (verbal processing, pictures in the depressed group. Additionally, a positive imagery deficit in depression was observed in the explicit measure. Interestingly, the two groups did not differ in implicitly assessed affect after positive imagery, indicating that depressed individuals might benefit from positive imagery on an implicit or automatic level. Overall, our findings suggest that mental imagery also plays an important role in depression and confirm the potential of novel treatment approaches for depression such as the promotion of positive imagery.

In adult Dutch, hoeven is an NPI that necessarily scopes under negation, giving rise to a NOT > NECESSARY reading. The findings from a hidden-object task with 5- and 6-year-old children showed that children's performance is suggestive of an interpretation of sentences with hoeft niet in which the modal scopes over negation (NECESSARY > NOT). This is in line with the Semantic Subset Principle that dictates that children should opt for the strongest possible reading in case of potential scope ambiguities. The full pattern of results, however, seems to be determined, in addition, by a particular strategy children use when facing uncertainty called Premature Closure.

    Zhang, Peng; Le, Son T.; Hou, Xiaoxiao; Zaslavsky, A.; Perea, Daniel E.; Dayeh, Shadi A.; Picraux, S. T.

    2014-08-01

    We report on room-temperature negative transconductance (NTC) in axial Si/Ge hetero-nanowire tunneling field-effect transistors. The NTC produces a current peak-to-valley ratio >45, a high value for a Si-based device. We characterize the NTC over a range of gate VG and drain VD voltages, finding that NTC persists down to VD = -50 mV. The physical mechanism responsible for the NTC is the VG-induced depletion in the p-Ge section that eventually reduces the maximum electric field that triggers the tunneling ID, as confirmed via three-dimensional (3D) technology computer-aided design simulations.

  9. Starting off on the right foot: strong right-footers respond faster with the right foot to positive words and with the left foot to negative words.

    Recent studies have provided evidence for an association between valence and left/right modulated by handedness, which is predicted by the body-specificity hypothesis (Casasanto, 2009) and also reflected in response times. We investigated whether such a response facilitation can also be observed with foot responses. Right-footed participants classified positive and negative words according to their valence by pressing a key with their left or right foot. A significant interaction between valence and foot only emerged in the by-items analysis. However, when dividing participants into two groups depending on the strength of their footedness, an interaction between valence and left/right was observed for strong right-footers, who responded faster with the right foot to positive words, and with the left foot to negative words. No interaction emerged for weak right-footers. The results strongly support the assumption that fluency lies at the core of the association between valence and left/right.

    Full Text Available In my paper, I want to put the prevailing crisis policy of the EU in a broader context of ‚judicialization‘ of democratic politics. Building on the works on ‚new constitutionalism‘ (mainly by Stephen Gill and Ran Hirschl and ‚authoritarian statism‘ (Nicos Poulantzas, I thoroughly and critically analyse the ratified EU-regulations and treaties with regard to their impact on democratic freedoms and the competences of legislature bodies. Based on this, I point out that even in the period before the current multiple crises, extensive and intensive judicialization of politics took place; that policies are being enforced increasingly authoritatively and partly outside established European Union law.

  11. EU Enlargement

    Pedersen, Peder J.; Pytlikova, Mariola

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

    Liu, Lihong; Wang, Le; Zhang, Chenning; Cho, Yujin; Dierre, Benjamin; Hirosaki, Naoto; Sekiguchi, Takashi; Xie, Rong-Jun

    2015-06-01

    A series of Eu(2+)- and Mn(2+)-codoped γ-AlON (Al1.7O2.1N0.3) phosphors was synthesized at 1800 °C under 0.5 MPa N2 by using the gas-pressure sintering method (GPS). Eu(2+) and Mn(2+) ions were proved to enter into γ-AlON host lattice by means of XRD, CL, and EDS measurements. Under 365 nm excitation, two emission peaks located at 472 and 517 nm, resulting from 4f(6)5d(1) → 4f(7) and (4)T1(4G) → (6)A1 electron transitions of Eu(2+) and Mn(2+), respectively, can be observed. Energy transfer from Eu(2+) to Mn(2+) was evidenced by directly observing appreciable overlap between the excitation spectrum of Mn(2+) and the emission spectrum of Eu(2+) as well as by the decreased decay time of Eu(2+) with increasing Mn(2+) concentration. The critical energy-transfer distance between Eu(2+) and Mn(2+) and the energy-transfer efficiency were also calculated. The mechanism of energy transfer was identified as a resonant type via a dipole-dipole mechanism. The external quantum efficiency was increased 7 times (from 7% for γ-AlON:Mn(2+) to 49% for γ-AlON:Mn(2+),Eu(2+) under 365 nm excitation), and color-tunable emissions from blue-green to green-yellow were also realized with the Eu(2+) → Mn(2+) energy transfer in γ-AlON.

  14. Bubble Formation within Filaments of Melt-Processed Bi2212 wires and its strongly negative effect on the Critical Current Density

    2011-01-01

    Most studies of Bi2Sr2CaCu2Ox (Bi2212) show that the critical current density Jc is limited by the connectivity of the filaments, but what determines the connectivity is still elusive. Here we report on the role played by filament porosity in limiting Jc. By a microstructural investigation of wires quenched from the melt state, we find that porosity in the unreacted wire agglomerates into bubbles that segment the Bi2212 melt within the filaments into discrete sections. These bubbles do not disappear during subsequent processing because they are only partially filled by Bi2212 grains as the Bi2212 forms on cooling. Correlating the microstructure of quenched wires to their final, fully processed Jc values shows an inverse relation between Jc and bubble density. Bubbles are variable between conductors and perhaps from sample to sample, but they occur frequently and almost completely fill the filament diameter, so they exert a strongly variable but always negative effect on Jc. Bubbles reduce the continuous Bi221...

    Mayoral Diaz-Asensio, Juan Antonio; Jaremba, Urszula; Nowak, Tobias

    2014-01-01

    The judicial protection system in the European Union (EU) is premised on the fact that national judges are supposed to act as decentralized EU judges. This role is exercised through tools enshrined in, inter alia, primacy, direct and indirect effect of EU law, and the preliminary ruling procedure....... However, a number of studies show that national judges experience difficulties in exercising EU competences due to their lack of knowledge in the field of EU law. In this contribution we study the differences in the level of self-evaluation of EU law knowledge among judges, which consequently influence...... the way judges approach EU law. For that purpose we question the relevance of several institutional and socio-legal factors, such as organization of the judiciary, generation, the system of legal education and judicial training and practical experience with EU law. Our analysis is based on data collected...

    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.

  4. Health, alcohol and EU law: understanding the impact of European single market law on alcohol policies.

    Baumberg, Ben; Anderson, Peter

    2008-08-01

    Many professionals in the alcohol field see the role of the the European Court of Justice (ECJ) as negative for health. This review examines ECJ and European Free Trade Association (EFTA) case law in the context of two broader debates: firstly the extension of European Union (EU) law into alcohol policy (the 'juridification' of alcohol policy), and secondly the extent to which alcohol policy is an example of the dominance of 'negative integration' (the removal of trade-distorting policy) over 'positive integration' (the creation of European alcohol policies). A comprehensive review of all ECJ/EFTA Court cases on alcohol, with interpretation aided by a secondary review on alcohol and EU law and the broader health and trade field. From looking at taxation, minimum pricing, advertising and monopoly policies, the extension of the scope of the these courts over alcohol policy is unquestionable. However, the ECJ and EFTA Court have been prepared to prioritize health over trade concerns when considering alcohol policies, providing certain conditions have been met. While a partial juridification of alcohol policy has led to the negative integration of alcohol policies, this effect is not as strong as sometimes thought; EU law is more health friendly than it is perceived to be, and its impact on levels of alcohol-related harm appears low. Nevertheless, lessons emerge for policymakers concerned about the legality of alcohol policies under EU law. More generally, those concerned with alcohol and health should pay close attention to developments in EU law given their importance for public health policy on alcohol.

    In the European Union (EU), employment policy is a prerogative of the member states. Therefore the EU's ability to govern in this area depends on its capability to involve national governments and relevant stakeholders in a collaborative effort to formulate and implement shared policy objectives....... Drawing an analytical distinction between cooperation, coordination and collaboration, the article analyses the formulation and implementation of EU employment policies. It concludes that while the formulation of policy objectives and the discussion of national policy approaches do involve elements...... of collaboration, the implementation phase mainly consists in the less demanding forms of cooperation and coordination....

    This paper discusses the changing relationship between the EU and Vietnam, and asks whether there is a shift from a “parental” to a “competitive” relationship. The focus of the paper is on the shift from aid to trade as the main interface between the EU and Vietnam. Aid relationships are often...... understood as hierarchical, linking a benevolent donor to a needy recipient, whereas commercial relationships are typically expected to involve a more competitive relationship. However, we argue that the bilateral relationship was never a “parental” one, even at the time when Vietnam’s relation to the EU...... 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. Instead, there has been substantial tension between the donor community and Vietnam...

    Directory of Open Access Journals (Sweden)

    Ines Kersan-Škabić

    2017-01-01

    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.

  7. The EU's Convergence Dilemma

    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

    YVO 4 nanocrystals doped with 10.0 mol% Eu 3+ have been synthesized from an aqueous solution of (Y,Eu)(NO 3 ) 3 and NH 4 VO 3 with or without ultrasonic irradiation. The ultrasonic irradiation has a strong effect on the morphology of the YVO 4 :Eu particles. The spindle-like particles with an equatorial diameter of 90-150 nm and a length of 250-300 nm could be obtained with ultrasonic irradiation, whereas only nanoparticles were produced without ultrasonic irradiation. The photoluminescence intensity of YVO 4 :Eu of the spindle-like particles was largely improved compared with that of the nanoparticles. The possible formation mechanism of the spindle-like particles of YVO 4 :Eu with the application of ultrasonic irradiation was discussed in this paper

    2010-12-01

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

  13. EU COMPARISON OF VAT

    Directory of Open Access Journals (Sweden)

    MARIA ZENOVIA GRIGORE

    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.

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

    International Nuclear Information System (INIS)

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

    2016-01-01

    This paper studies various options to support allowance prices in the EU Emissions Trading System (ETS), such as adjusting the cap, an auction reserve price, and fixed and variable carbon taxes in addition to the EU ETS. We use a dynamic computable general equilibrium model that explicitly allows for allowance banking and for a detailed cost-effectiveness analysis at the EU Member State level. We find that tightening the cap provides an ad hoc solution to the fundamental issue of the robustness of the effective carbon price, while introducing a price component to the ETS brings structural carbon price support in times of negative demand shocks for emission allowances. These price-based policies still benefit from the intertemporal flexibility through the banking provision in the EU ETS by re-allocating emissions over time with stronger emission reductions in early years and emission increases in later years. A higher emission price has a larger negative impact on the new Member States' economies than on other Member States. Furthermore, introducing a carbon tax in addition to the EU ETS decreases the price of allowances, resulting in welfare gains for net buyers of allowances while net sellers are worse off. - Highlights: • We analyse reform options for European Union Emission Trading System (EU ETS) with a CGE model. • Variable carbon tax and auction reserve price support carbon price at least cost. • Price-based reforms decrease early emissions but increase later emissions through banking. • New Member States' economies are affected more than others by higher CO 2 prices. • Lower allowance prices due to a carbon tax are unfavourable to net sellers of allowances.

    2014-01-01

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

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

    Energy Technology Data Exchange (ETDEWEB)

    Philippidis, G.

    2010-07-01

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

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

    International Nuclear Information System (INIS)

    Jansen, H.; Klaassen, G.

    2000-01-01

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

    2004-07-01

    Full Text Available This article deals with one of the most important, but also challenging economic issues nowadays, which is economic competitiveness. The literature is not unanimous in recognizing the importance of competitiveness, especially where it concerns the state level. However, the relevance of international competitiveness is increasingly brought into light by theory, specific policy measures and by periodical evaluations made by international organizations. Against this background, the EU is one of the main players whose position is still lagging behind the USA, and, according to recent evaluations, behind the other OECD countries. The European Council in March 2000, held in Lisbon, had launched a very inciting challenge – that of transforming the EU economy into the most competitive and dynamic knowledge-based economy in the world, by 2010. Such an ambitious target requires an evaluation of the competitiveness level and also new measures to be taken in order to accomplish this objective.The article presents opinions on the EU competitiveness issue, and on the main weak and strong points, concluding that even the target and especially the schedule seem to be unrealistic, the new direction of action, i.e. towards better business conditions for enterprises being correct.

    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.

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. 

  17. Technology Transfer in the EU: Exporting Strategically Important ICT Solutions to Other EU Member States

    Directory of Open Access Journals (Sweden)

    Säär Anni

    2015-10-01

    Full Text Available The fast development of ICTs pose new challenges to the European Union and its Member States. Every EU country has its own policies regarding technology transfer, ownership of state e-services, and the possibilities how the state-owned or licensed e-service could be exported. Taking into account the free movement of goods, the EU has created a platform to cooperate and export IT solutions. However, the lack of preparedness of infrastructures, legislation and stakeholders for cross-border exchanges poses a threat to IT transfer and should be taken into consideration in the EU as well. In the coming decades the number of outsourced ICT solutions, strategically important ICT solutions, public services and critically important information exchange platforms developed on behalf of the states, will grow exponentially. Still, digital development is uneven across the EU, they grow at different speeds and the performance is quite splintered. There are legal provisions which are outdated and therefore impede technological cooperation and export of IT solutions. A Member State may restrict the ICT licensing based on national security and policy reasons and the ownership of intellectual property might pose a threat to technology transfer or further development of the IT solution. There are examples of strategically important export of ICT solutions, the experience at which can be expanded to cover other EU Member States. Strong collaboration would enable mutual learning from past experiences along with the opportunities for better use of technology. Parallels can be drawn with military technology transfers, as the policies and legal framework was first developed and mostly used with them.

    In the EU, the EMA has been working with biosimilars since 1998. This experience is crystallized in the extensive set of guidelines, which range from basic principles to details of clinical trials. While the guidance may appear complicated, it has enabled the development of biosimilars, of which 21 have managed to get marketing authorization. Currently marketed biosimilars in the EU have a good track record in safety and traceability. No biosimilars have been withdrawn from the market because of safety concerns. The most controversial issues with biosimilars are immunogenicity and extrapolation of therapeutic indications. The available data for these topics do not raise concerns among EU regulators. Interchangeability and substitution are regulated by individual EU member states.

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.

  1. Chinese investments in the EU

    Full Text Available China’s investments in the European Union are much lower than what you may expect given the economic size of both entities. 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.

    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.

    Full Text Available With over twenty years ago, Romania was a big producer of meat, with breeding pigs steers and lambs farms, throughout the country. At present, the meat industry has declined considerably. For many years, however, Romania from the exporter of meat has become a fresh meat and meat products importer. Meat consumption per capita in Romania is about half the EU average (92 kg. Romanians show a strong preference for pork, although chicken meat consumption is increasing. The current financial crisis will trigger a decline in terms of meat consumption in EU countries including in Romania.

    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

    Comparative adsorption behaviors of Eu(III) and Am(III) on thorium phosphate diphosphate (TPD), i.e., Th4(PO4)4P2O7, have been studied using a batch approach and surface complexation model (SCM) in this study. The results showed that Eu(III) and Am(III) adsorption increased to a large extent with the increase in TPD dose. Strong pH-dependence was observed in both Eu(III) and Am(III) adsorption processes, suggesting that inner-sphere complexes (ISCs) were possibly responsible for the adsorption of Eu(III) and Am(III). Meanwhile, the adsorption of Eu(III) and Am(III) decreased to a different extent with the increase in ion strength, which was possibly related to outer-sphere complexes and/or ion exchange. In the presence of fulvic acid (FA), the adsorption of Eu(III) and Am(III) showed high enhancement mainly due to the ternary surface complexes of TPD-FA-Eu(3+) and TPD-FA-Am(3+). The SCM showed that one ion exchange (≡S3Am/Eu) and two ISCs (≡(XO)2Am/EuNO3 and ≡(YO)2Am/EuNO3) seemed more reasonable to quantitatively describe the adsorption edges of both Eu(III) and Am(III). Our findings obviously showed that Eu(III) could be a good analogue to study actinide behaviors in practical terms. However, it should be kept in mind that there are still obvious differences between the characteristics of Eu(III) and Am(III) in some special cases, for instance, the complex ability with organic matter and adsorption affinity to a solid surface.

    Full Text Available BACKGROUND: 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. METHODOLOGY/PRINCIPAL FINDINGS: 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. CONCLUSIONS/SIGNIFICANCE: 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.

    Full Text Available Our first research objective is to outline the degree of dependence on EU trade and investment of the CEE countries included in the 16+1 platform, as well as their attitudes towards the EU. The resulting EU dependence/attitude matrix helps us to identify four groups of CEE countries according to their lower/higher dependence on EU trade and investment, alongside their negative/positive attitudes towards the EU. Our second objective is to classify CEE-16 according to their cooperation intensity with China, as mirrored by their economic and political ties with China. Our investigation underlines that: (1 higher levels of cooperation intensity with China are generally correlated with negative attitudes towards the EU, importance of national interests and need to develop balanced relations with major global actors; (2 lower levels of cooperation intensity with China correspond to euro-optimist/moderate stances, extreme dependence on the internal market or political inertia.

  12. Achieving Economic Growth in the EU Through Lobbyism

    Directory of Open Access Journals (Sweden)

    Gert Tinggaard Svendsen

    2009-11-01

    Full Text Available At Lisbon in 2000, the European Union (EU set itself a new strategic goal, namely to become the world’s leading economy and to enhance social cohesion across the union, all within a decade. It is argued in this article that one fundamental barrier to the fulfilment of this dream is the fact that power is centralised in the Commission rather than the Parliament. The basic idea upon which our theoretical model is predicated is that a political system that centralises power lowers the cost of rent-seeking and therefore leads to a more economically harmful redistribution, as reflected in the annual EU budget. Here, the two main redistribution policies, (1 Common Agricultural Policy (CAP and (2 the Structural Funds, consume more than four fifths of the total annual EU budget. Thus, if the EU is to achieve its strategic goal, a strong cure is needed to reduce redistribution and encourage more free trade. The simple cure for this ‘EU disease’ would be to strengthen the decision-making power of the Parliament at the expense of the Commission. In this way, power would be spread out between the democratically elected members of the Parliament rather than being concentrated with a few bureaucrats. Such constitutional change and decentralisation of power would increase the costs of lobbyism in particular and thereby reduce distortions of policy outcomes, clearing the road for free-trade policies and economic growth in the new millennium.

    The European Union (EU) refers to health as a human right in many internal and external communications, policies and agreements, defending its universality. In parallel, specific health needs of migrants originating from outside the EU have been acknowledged. Yet, their right to health and in particular sexual and reproductive health (SRH) is currently not ensured throughout the EU. This paper reflects on the results of a comprehensive literature review on migrants' SRH in the EU applying the Critical Interpretive Synthesis review method. We highlight the discrepancy between a proclaimed rights-based approach to health and actual obstacles to migrants' attainment of good SRH. Uncertainties on entitlements of diverse migrant groups are fuelled by unclear legal provisions, creating significant barriers to access health systems in general and SRH services in particular. Furthermore, the rare strategies addressing migrants' health fail to address sexual health and are generally limited to perinatal care and HIV screening. Thus, future European public health policy-making should not only strongly encourage its Member States to ensure equal access to health care for migrants as for EU citizens, but also promote migrants' SRH effectively through a holistic and inclusive approach in SRH policies, prevention and care.

    2014-10-01

    Full Text Available An alarming decision “to pause” the process of Ukrainian Eurointegration taken by the previous government of Ukraine, turned out to be highly disturbing, both to the Ukrainian people and the EU in terms of planned partnership. Following the country’s course change a series of dramatic events unraveled triggering a mass protest movement called Euromaidan across major part of Ukraine, indicating the position of Ukrainian society towards the events. The further unfolding of the events in the Ukraine starting from November 22, 2013 diminished the “euro” direction making it solemnly “MAIDAN”. The direction of Eurointegration in Ukraine’s foreign policy was no longer the priority of the rebel movement, shifting the focus of those protesting to the internal issues. During the Maidan the EU’s representatives initiated and participated in the negotiation process between the government and the opposition, thus demonstrating support to Ukraine on its way to democracy. In the meantime, Maidan expected stricter sanctions towards representatives of the state at that time: freezing of the accounts of those associated with corruption as well as their visa bans and restrictions for travel and business conduction in the EU, etc.. The EU’s lasting conservative behavior was regarded negatively by protesters and lead to disappointment.

    Temperature measurements and thermal mapping using luminescent MOF operating in the high-temperature range are of great interest in the micro-electronic diagnosis. In this paper, we report a thermostable Eu/Tb-mixed MOF Eu{sub 0.37}Tb{sub 0.63}-BTC-a exhibiting strong luminescence at elevated temperature, which can serve as a ratiometric luminescent thermometer for high-temperature range. The high-temperature operating range (313–473 K), high relative sensitivity and accurate temperature resolution, make such a Eu/Tb-mixed MOF useful for micro-electronic diagnosis. - Graphical abstract: A thermostable Eu/Tb-mixed MOF Eu{sub 0.37}Tb{sub 0.63}-BTC-a was developed as a ratiometric luminescent thermometers in the high-temperature range of 313–473 K. - Highlights: • A thermostable Eu/Tb-codoped MOF exhibiting strong luminescent at elevated temperature is reported. • The high-temperature operating range of Eu{sub 0.37}Tb{sub 0.63}-BTC-a is 313–473 K. • The mechanism of Eu{sub 0.37}Tb{sub 0.63}-BTC-a used as thermometers are also discussed.

    Ce 1%, Eu 1%, and Eu 2%-doped LiSrAlF 6 (LiSAF) single crystals were grown by the micro-pulling-down method for thermal neutron applications. The crystals were transparent, 2.0 mm in diameter and 20–40 mm in length. Neither visible inclusions nor cracks were observed. Their transmittance spectra were measured. The strong absorption lines were observed at 200, 240, and 300 nm for Ce:LiSAF due to Ce 3+ 4f–5d transition. In Eu:LiSAF, 200 (4f–5d) and 300 (4f–4f) nm absorption lines were detected. The samples demonstrated strong emission peaks at 300 nm (Ce:LiSAF) and 370 nm (Eu:LiSAFs) when they were irradiated with 241 Am α-rays simulating the α-particles from the 6 Li(n, α) reaction. Thermal neutron responses were examined under 252 Cf irradiation. The absolute light yield of Ce, Eu 1%, and Eu 2% crystals were 3400, 18000, and 30000 ph/n, respectively. Main components of the scintillation decay time of Ce, Eu 1%, and Eu 2%-doped LiSAFs were 63, 1293, and 1205 ns.

  19. Markets for energy efficiency: Exploring the implications of an EU-wide 'Tradable White Certificate' scheme

    International Nuclear Information System (INIS)

    Mundaca, Luis

    2008-01-01

    Recent developments in European energy policy reveal an increasing interest in implementing the so-called 'Tradable White Certificate' (TWC) schemes to improve energy efficiency. Based on three evaluation criteria (cost-effectiveness, environmental effectiveness and distributional equity) this paper analyses the implications of implementing a European-wide TWC scheme targeting the household and commercial sectors. Using a bottom-up model, quantitative results show significant cost-effective potentials for improvements (ca. 1400 TWh in cumulative energy savings by 2020), with the household sector, gas and space heating representing most of the TWC supply in terms of eligible sector, fuel and energy service demand, respectively. If a single market price of negative externalities is considered, a societal cost-effective potential of energy savings above 30% (compared to the baseline) is observed. In environmental terms, the resulting greenhouse gas emission reductions are around 200 Mt CO 2-eq by 2010, representing nearly 60% of the EU-Kyoto-target. From the qualitative perspective, several embedded ancillary benefits are identified (e.g. employment generation, improved comfort level, reduced 'fuel poverty', security of energy supply). Whereas an EU-wide TWC increases liquidity and reduces the risks of market power, autarky compliance strategies may be expected in order to capture co-benefits nationally. Cross subsidies could occur due to investment recovery mechanisms and there is a risk that effects may be regressive for low-income households. Assumptions undertaken by the modelling approach strongly indicate that high effectiveness of other policy instruments is needed for an EU-wide TWC scheme to be cost-effective

  7. A study of the local structure around Eu3+ ions in oxide glasses using Moessbauer spectroscopy

    International Nuclear Information System (INIS)

    Todoroki, S.; Hirao, K.; Soga, N.

    1993-01-01

    The local structure around Eu 3+ ions in several oxide glasses (silicate, germanate and borophosphate glasses) was investigated by using 151 Eu Moessbauer spectroscopy. It was found that the isomer shift (IS) of silicate and borophosphate glasses was independent of the sodium content, but that of germanate glasses was not. This means the first coordination sphere around Eu 3+ ions in silicate glasses is insensitive to the composition of the glass matrix. It is assumed that, regardless of the sodium content, Eu 3+ ions in silicate glasses attract a certain amount of nonbridging oxygen (NBO, Si-O direct difference ) when incorporated stably into silicate glass matrix, because NBO is the only species donating negative charge. For germanate glasses, the behavior of IS is considered to be related to the resence of GeO 6/2 octahedra. On the basis of experimental results, the coordination models of Eu 3+ in these systems are proposed. (orig.)

Therefore, this article investigates the reasons for the EU’s non-application of Article 96 of the Cotonou Agreement in five countries that can be considered typical cases where negative conditionality is generally imposed, namely countries that experienced flawed elections over the last ten years: Ethiopia, Rwanda, Nigeria, Kenya and Chad. On the one hand, the study confirms previous findings that security interests tend to trump the EU’s efforts to promote democratisation. On the other hand, the article adds that democratisation might not only conflict with the EU’s interests, but also with its objective to promote development and poverty reduction.

  14. Negative Ion Density Fronts

    International Nuclear Information System (INIS)

    Igor Kaganovich

    2000-01-01

    Negative ions tend to stratify in electronegative plasmas with hot electrons (electron temperature Te much larger than ion temperature Ti, Te > Ti ). The boundary separating a plasma containing negative ions, and a plasma, without negative ions, is usually thin, so that the negative ion density falls rapidly to zero-forming a negative ion density front. We review theoretical, experimental and numerical results giving the spatio-temporal evolution of negative ion density fronts during plasma ignition, the steady state, and extinction (afterglow). During plasma ignition, negative ion fronts are the result of the break of smooth plasma density profiles during nonlinear convection. In a steady-state plasma, the fronts are boundary layers with steepening of ion density profiles due to nonlinear convection also. But during plasma extinction, the ion fronts are of a completely different nature. Negative ions diffuse freely in the plasma core (no convection), whereas the negative ion front propagates towards the chamber walls with a nearly constant velocity. The concept of fronts turns out to be very effective in analysis of plasma density profile evolution in strongly non-isothermal plasmas

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

    Energy Technology Data Exchange (ETDEWEB)

    Christensen, Anne Raaum; Gulbrandsen, Lars H.

    2012-07-01

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

    We report a study of the phosphate glass PZABP (P{sub 2}O{sub 5}–ZnO–Al{sub 2}O{sub 3}–BaO–PbO) doped with europium (Eu{sup 3+}) in different concentrations. Absorption, photoluminescence and time resolved photoluminescence were used to investigate the influence of increasing Eu{sup 3+} concentrations. The present glass exhibits Eu{sup 3+} absorption bands in the ultraviolet region (about 300 nm) due to the high transparency of the system compared to other phosphate glasses. In this way, it was possible to obtain the Judd–Ofelt parameters from the emission and absorption spectra. Moreover, a strong red emission attributed to the transition {sup 5}D{sub 0}→{sup 7}F{sub 2} of Eu{sup 3+} (611 nm) was observed. It was found that the radiative lifetime and the quantum efficiency of the Eu{sup 3+} level, {sup 5}D{sub 0}, do not suffer a significant change as the concentration of Eu{sup 3+} ions increases. - Highlights: • UV transparent glass matrix is used for Eu{sup 3+} doping. • Judd–Ofelt parameters from the emission and absorption spectra were obtained. • Red emission attributed to the transition {sup 5}D{sub 0}→{sup 7}F{sub 2} of Eu{sup 3+} (611 nm) was observed.

    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.

    Metal–insulator transitions (MITs) offer new functionalities for nanoelectronics. However, ongoing attempts to control the resistivity by external stimuli are hindered by strong coupling of spin, charge, orbital and lattice degrees of freedom. This difficulty presents a quest for materials which exhibit MIT caused by a single degree of freedom. In the archetypal ferromagnetic semiconductor EuO, magnetic orders dominate the MIT. Here we report a new approach to take doping under control in this material on the nanoscale: formation of oxygen vacancies is strongly suppressed to exhibit the highest MIT resistivity jump and magnetoresistance among thin films. The nature of the MIT is revealed in Gd doped films. The critical doping is determined to be more than an order of magnitude lower than in all previous studies. In lightly doped films, a remarkable thermal hysteresis in resistivity is discovered. It extends over 100 K in the paramagnetic phase reaching 3 orders of magnitude. In the warming mode, the MIT is shown to be a two-step process. The resistivity patterns are consistent with an active role of magnetic polarons—formation of a narrow band and its thermal destruction. High-temperature magnetic polaron effects include large negative magnetoresistance and ferromagnetic droplets revealed by x-ray magnetic circular dichroism. Our findings have wide-range implications for the understanding of strongly correlated oxides and establish fundamental benchmarks to guide theoretical models of the MIT.

    Full Text Available EU Humanitarian Programs in the Southern Caucasus States are considered in the article. The increasing number and importance of the programs developing person-toperson contacts for the conflicting areas are noted. The influence of TRACECA and INOGATE programs was very significant in developing the local economies. Humanitarian aspects became important since 1992 when the first peace-building conferences of the Minsk group on Nagorno-Karabakh conflict took place. The political cooperation was institutionalized in 2004 with the implementing the European Neighborhood program. According to the “Eastern Partnership” a number of grants was offered to develop so called “new democracies”. A lot of educational programs provided the space for the personal cooperation in the area now are implementing. Mobility Partnerships program provides the regional cooperation in the migration policy. Consequently all the EU programs make the European volumes popular for the Caucasian inhabitants. That’s why the author puts the question about possible transformations in the regional identity. The states elites declare the importance for developing close contacts with EU institutes. Still there are some arguable issues. The status of sexual minorities in Azerbaijan provides the base for the mutual discontent in their relations with EU. Yet Azerbaijan has enough financial resources (based on the petrol supplies to reduce the EU influence in some objectionable fields. Georgia under M. Saakashvili ruling showed a strong trend towards EU and “Western” values on the whole. But this trend was mainly based on the strategies of the state financial surviving. There are some evidences proving that the main target of this police was to make a distance from the Russian policy. Armenia may be introduces as the state with strong interests in European cooperation for developing its economy. But there are also some important projects connecting Armenia with Russia, still

    The kinetics of complexation (C) and decomplexation (D) reactions between Eu(III) and Aldrich humic acid (HA) was investigated as a function of pH (pH 4, 5, 6, 7 and 8) in the system Eu(III) - HA - Amberlite IR-120(Na) (I 0.1). The derivation of the kinetic differential equations was based on the reactions of Eu 3+ with, so called, strong (HAS) and weak (HAW) carboxylic groups of HA formulated in accordance with the new complexation model. The differential equations determining d[Eu a HAS]/dt and d[Eu b HAW]/dt have the classical form applicable for reversible reactions where the forward reaction is the C-reaction and the reverse one is the D-reaction. Kinetic model used for the evaluation of experimental data includes these differential equations and the film diffusion model of sorption of Eu 3+ on Amberlite IR-120(Na). (author)

    2014-01-01

    We examine the social desirability of renewable diesel production from imported palm oil in the EU when greenhouse gas emissions are taken into account. Using a partial market equilibrium model, we also study the sectoral social welfare effects of a biofuel policy consisting of a blend mandate in a small EU country (Finland), when palm oil based diesel is used to meet the mandated quota for biofuels. We develop a market equilibrium model for three cases: i) no biofuel policy, ii) biofuel policy consisting of socially optimal emission-based biofuel tax credit and iii) actual EU biofuel policy. Our results for the EU biofuel market, Southeast Asia and Finland show very little evidence that a large scale use of imported palm oil in diesel production in the EU can be justified by lower greenhouse gas emission costs. Cuts in emission costs may justify extensive production only if low or negative land-use change emissions result from oil palm cultivation and if the estimated per unit social costs of emissions are high. In contrast, the actual biofuel policies in the EU encourage the production of palm oil based diesel. Our results indicate that the sectoral social welfare effects of the actual biofuel policy in Finland may be negative and that if emissions decrease under actual biofuel policy, the emission abatement costs can be high regardless of the land use change emissions. - Highlights: • We study the social desirability of renewable diesel production from palm oil in EU. • We also study sectoral social welfare impacts of actual biofuel policy in Finland. • Life cycle GHG emission costs of diesels are included in the economic analysis. • Extensive use of palm oil diesel in EU is difficult to justify by climate benefits. • The social welfare effects of the actual biofuel policy in Finland can be negative

    Eu, Tb co-doped SrAl{sub 2}Si{sub 2}O{sub 8} luminescent materials were synthesized via a high-temperature solid-state reaction. Excitation spectra of SrAl{sub 2}Si{sub 2}O{sub 8}: Eu{sup 2+} gives two broad excitation bands maximizing at 270 and 330 nm, resulting from splitting Eu{sup 2+} energy levels in octahedral crystal field. Eu single doped SrAl{sub 2}Si{sub 2}O{sub 8} luminescent material exhibits two emission bands at about 406 and 616 nm. Intensity of the blue emission from Eu{sup 2+} is always strong, compared with that of the red emission band of Eu{sup 3+}. Reduction from Eu{sup 3+} to Eu{sup 2+} can be explained with the model of charge compensation. Blue emission in SrAl{sub 2}Si{sub 2}O{sub 8}: xEu was strengthened after incorporation of Tb, which can be explained by electron transfer from Tb{sup 3+} to Eu{sup 3+} (Tb{sup 3+} + Eu{sup 3+} → Tb{sup 4+} + Eu{sup 2+}). Under 230 nm excitation, intensity of Tb{sup 3+} emission was nearly unchanged and that of Eu{sup 2+} was increased, obviously due to the delivery of more electrons to Eu{sup 3+}. The strongest emission of Eu{sup 2+} in 0.09Eu/0.06Tb co-doped SrAl{sub 2}Si{sub 2}O{sub 8} and excited at 270 and 330 nm was remarkably enhanced by about four times compared to that of 0.15Eu Single doped SrAl{sub 2}Si{sub 2}O{sub 8}. All of the results indicate that SrAl{sub 2}Si{sub 2}O{sub 8}:xEu, yTb are potential blue emitting luminescent materials for UV-LEDs. More importantly, this research may provide a new perspective in designing broad band blue luminescent materials. (copyright 2017 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim)

  16. State aid in the EU law and national law

    Directory of Open Access Journals (Sweden)

    Divljak Drago

    2011-01-01

    Full Text Available Due to emphasized negative implications, state aid in contemporary law is more and more the subject of legal rules of supra-national and international law, and consequently it is more and more frequently the subject of national laws. The systems of state aid are based on the principle of general non-allowedness of state aid, which is relativised with wide exceptions and the form of allowed and conditionally allowed forms of state aid. In the EU law, a complex and differentiated system of legal regime on state aid is created aimed at preventing the Member States to protect or promote their companies at the expense or harm of competition within the EU. Compared to the regulations that refer to subsidies and that are created at the international level, within the WTO, these regulations are much more detailed and they cover a wide spectrum of different forms of state aid. National laws are accepting the EU concept as a novelty, which is valid in particular for countries in the process of the EU integrations. This has been done in our law as well by enacting of the Law on state aid control. This Law regulates general conditions for granting, granting control, and utilization of state assistance, with the essential objective to establish and provide for competitive market conditions and introduction of order in the field that has not been regulated previously. At the same time, this means a successful fulfillment of the obligations related to pre-accession harmonization of this field, which is a necessary pre-condition for accession of our country into this group of countries since the EU standards and requirements have been fully observed with the above-mentioned Law.

    Lobbying in the EU is difficult to measure. It varies in intensity and modes of expression across different policy areas and EU countries. By looking at a specific EU policy area this paper suggests to measure differences in the lobbying activity across EU countries by the combination...... of petitioning firms and Council voting in the case of anti-dumping policy.

    Despite the fact that Member States and many citizens of the EU like to keep healthcare a foremost national competence and the EU treaties state that Member States remain primarily responsible for the organization and delivery of health care services, the European Union (EU) has expanded its...... involvement in healthcare policy over the last twenty years. Based on interviews and document and literature analysis we show that the scope of EU involvement has widened from public health and access to care, to quality of care. In this paper we concentrate on the latter. Focusing on the recent EU...... initiatives regarding the quality systems of the Member States and the quality of services, this paper shows how the depth of EU interference has increased from sharing information to standardization and even to the first signs of enforcement. We argue that at this stage, reflection on the feasibility...

    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...

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

    Full Text Available The new Silk Road Economic Belt and 21st Century Maritime Silk Road (OBOR is a historic opportunity for further Sino-EU maritime cooperation, as both sides have much to share and more to build in terms of vision, policies, and security, making it possible for a new line in the already-thriving exchanges across the continent. The two sides will carry on the China-EU 2020 Strategic Agenda for Cooperation with fusion of maritime strategies and joint efforts for safer sea passage, and may proceed to a Maritime Cooperative Organization (MCO when needed to build not only a participative maritime order, but also next-gen cooperation between Asia, Africa, and Europe. Yet this still needs a well-assorted toolset of bi- and multilateral cooperation backed by strong policy and theory, to boost consensus and action by management of differences.

  10. 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.

    Ab initio calculations on Eu doped (GaN){sub n} (n = 12, 13, and 32) nanoparticles show that Eu doping in nanoparticles is favorable compared with bulk GaN as a large fraction of atoms lie on the surface where strain can be released compared with bulk where often Eu doping is associated with a N vacancy. Co-doping of Si further facilitates Eu doping as strain from an oversized Eu atom and an undersized Si atom is compensated. These results along with low symmetry sites in nanoparticles make them attractive for developing strongly luminescent nanomaterials. The atomic and electronic structures are discussed using generalized gradient approximation (GGA) for the exchange-correlation energy as well as GGA + U formalism. In all cases of Eu (Eu + Si) doping, the magnetic moments are localized on the Eu site with a large value of 6μ{sub B} (7μ{sub B}). Our results suggest that co-doping can be a very useful way to achieve rare-earth doping in different hosts for optoelectronic materials.

  12. Fluctuation-induced first-order transition in Eu-based trillium lattices

    Science.gov (United States)

    Franco, Diego G.; Prots, Yurii; Geibel, Christoph; Seiro, Silvia

    2017-07-01

    Among spin arrangements prone to geometric frustration, the so-called trillium lattice has not been very intensively investigated. A few theoretical works show that it is at the border between a degenerate, an only partially ordered, and a fully ordered ground state. However, only few compounds with this structure have been studied, and there is presently no good example of a trillium lattice with an antiferromagnetic ground state and clear evidence for frustration effects. We present magnetic and specific heat measurements on two realizations of a trillium lattice of local spins, EuPtSi and EuPtGe. Both compounds exhibit a similar magnetic behavior, with Eu2 + moments ordering antiferromagnetically at TN=4.1 K (EuPtSi) and 3.3 K (EuPtGe), albeit retaining a considerable amount of entropy in strong magnetic fluctuations extending to temperatures well above TN. The magnetic entropy reaches only roughly half of R ln8 at TN. These fluctuations are presumably the source for the pronounced first-order character of the transition at TN and are likely due to magnetic frustration. Thus, EuPtSi and EuPtGe open a new door to experimental studies of frustration effects in the trillium lattice and provide a testing ground for theoretical predictions.

  16. Shifting policy priorities in EU-China energy relations: Implications for Chinese energy investments in Europe

    International Nuclear Information System (INIS)

    Gippner, Olivia; Torney, Diarmuid

    2017-01-01

    Shifting energy policy priorities both in China and the EU (European Union) have transformed their bilateral relationship. In order to assess the impact of domestic policy priorities on bilateral energy cooperation and climate policy, this comparative study traces the evolution of EU and Chinese approaches to energy policy – and their relative emphasis on factors and frames such as availability, efficiency, affordability and environmental stewardship. Drawing on government documents and a data set of interviews with Chinese policy-makers, experts and academics in 2015–2016, the article argues that while the EU started with a strong emphasis on environmental stewardship and moved towards a focus on affordability and availability, China started with a strong emphasis on availability and has moved towards a greater emphasis on environmental stewardship. This shift in frames on the Chinese side and subsequent changes in subsidy structures and targets can partially explain the increase in investments in renewable energy technologies. The article concludes that the Chinese and EU perspectives have become more aligned over the past ten years, coinciding with an increasing trend towards renewable energy in Chinese energy investments in the EU, for example in Italy and the UK. - Highlights: • Compares dominant frames of energy policy in China and the European Union in the period 2005–2015. • Shows that there has been a convergence of policy frames between China and the EU. • Convergence on environmental stewardship is necessary but not sufficient for FDI in clean energy.

  18. EU SDS. Ingredients for the 2006 revision

    International Nuclear Information System (INIS)

    De Ridder, W.; Wesselink, L.G.

    2006-01-01

    The current EU strategy for sustainable development comprises three separate components. Collectively, these comprise a broad spectrum of sustainable development goals, ranging from economic growth and more jobs to halting biodiversity loss and attaining millennium development goals such as poverty reduction. On paper, the entire EU Sustainable Development Strategy (EU SDS) reflects the different views on sustainable development. In reality, however, it is the so-called Lisbon strategy, whose goal it is to transform Europe into the most competitive area of the world by 2010, that dominates policy development in the EU. This focus on the Lisbon strategy is motivated by the assumption that competitiveness is a precondition for sustainable development. However, historical trends show that more growth has thus far not contributed to attaining the sustainable development goals for protection of the world's climate and biodiversity. The current EU SDS is not clear about the extent to which such trade-offs are accepted or about how further trade-offs will be avoided. There are also indications that large groups of EU citizens do not necessarily desire the EU to focus on the Lisbon strategy in favour to the other components of the EU SDS. Revising the EU SDS provides an opportunity to explicitly subordinate the Lisbon strategy to the EU SDS by creating one single document, endorsed and monitored by the EU Council, in which all goals for sustainable development are presented integrally. This document should then describe how the focus on Lisbon will contribute to sustainable development and how tradeoffs are dealt with. Trade-offs should ideally be scientifically underpinned and choices based on broad societal consultation

  19. Regionale Meeresschutzkooperation und die EU-Gratwanderung der Helsinki-Kommission imOsterweiterungsprozess der EU

    Imhoff, Heike

    1999-12-01

    The purpose of the lecture is to describe the role of regional marine protection cooperation in the context of international cooperation. My intention is to provide evidence that regional forms of cooperation are an indispensable instrument, in particular against the backdrop of the EU enlargement to the east. Signed at times when the iron curtain still existed, the Baltic Marine Environment Protection Convention was the basis of a first reluctant cooperation between Western and Eastem states bordering on the Baltic Sea. As a result of the fall of the iron curtain and of the accession of Finland and Sweden to the European Union there was a shift in the political structure of the Baltic Sea cooperation. 4 EU member states are represented in the Helsinki Commission. As there is a total of 10 Parties (one of them the Commission of the European Communities) this means that EU countries currently already make up 50% of the Commission. The regulatory instruments of the Helsinki Commission (legally non-binding, yet politically appellative recommendations) and of the EU (directives, regulations etc. which are binding by international law) make it clear that there are serious differences. From the point of view of regional marine protection cooperation, the EC Commission’s involvement in issues of regional marine protection has been linked to both advantages and disadvantages. The pressure created by the EC’s involvement in certain issues can be considered an advantage, since it requires that certain issues are continually addressed in the framework of regional marine protection cooperation. For example, in the wake of the adoption of the nitrates directive special rules were established in the framework of the Helsinki Commission. However, the exclusive competence for individual areas (e.g. fisheries) claimed by the EC Commission sometimes has negative effects. Those member states of the Helsinki Commission which are also EU member states may formally only accept rules

    Density functional theory in conjunction with COSMO and COSMO-RS solvation models employing dispersion correction (DFT-D3) has been applied to gain an insight into the complexation of Eu 3+ /Am 3+ with diglycolamide (DGA) and calix[4]arene appended diglycolamide (CAL4DGA) in ionic liquids by studying structures, energetics, thermodynamics and population analysis. The calculated Gibbs free energy for both Eu 3+ and Am 3+ ions with DGA was found to be smaller than that with CAL4DGA. The entropy of complexation was also found to be reduced to a large extent with DGA compared to complexation with CAL4DGA. The solution phase free energy was found to be negative and was higher for Eu 3+ ion. The entropy of complexation was not only found to be further reduced but also became negative in the case of DGA alone. Though the entropy was found to be negative it could not outweigh the high negative enthalpic contribution. The same trend was observed in the solution where the free energy of extraction, ΔG, for Eu 3+ ions was shown to be higher than that for Am 3+ ions towards free DGA. But the values of ΔG and ΔΔG(= ΔG Eu -ΔG Am ) were found to be much higher with CAL4DGA (-12.58 kcal mol -1 ) in the presence of nitrate ions compared to DGA (-1.69 kcal mol -1 ) due to enhanced electronic interaction and positive entropic contribution. Furthermore, both the COSMO and COSMO-RS models predict very close values of ΔΔΔG (= ΔΔG CAL4DGA - ΔΔG nDGA ), indicating that both solvation models could be applied for evaluating the metal ion selectivity. The value of the reaction free energy was found to be higher after dispersion correction. The charge on the Eu and Am atoms for the complexes with DGA and CAL4DGA indicates the charge-dipole type interaction leading to strong binding energy. The present theoretical results support the experimental findings and thus might be of importance in the design of functionalized ligands.

  1. Brussels without Muscles? Exploring the EU's Management of its Gas Relationship with Russia

    2010-03-01

    In many respects, the EU is a strong player on the world stage, for example, in trade, climate change issues and crisis management. In its relationship with Russia over gas supply, however, the EU's political capacity remains limited. Part of the problem lies in the lack of EU unity, but this is more a symptom than an actual cause. A key explanation is the interplay between external and internal factors. The external factors - that is the EU's and Russia's conflicting interests and the structure of the political system - reinforce the EU's internal problems. This is an effect of that the gas issue falls under different policy areas (energy, foreign relations and security policy) within which the European Commission and the member states have different responsibilities. Another problem is that energy is the Commission's responsibility, but the real competence lies with the member states. The current multipolar structure of European politics reduces the scope for cooperation that favours the EU as a whole - in this case its energy security. The fact that the Commission and member states, and the member states among themselves, have different views on energy policy vis-a-vis Russia exacerbates these circumstances. Other key factors are the lack of transparency and competition in the gas sector (which suits both the Russian company Gazprom and large EU companies) and the unbalanced dependence of EU countries on Russian gas. Relations between France, Germany and Russia are also important. Germany and France are key players for the EU's energy security, and their support for the gas pipeline Nord Stream, their resistance to unbundling in the gas sector and their relatively warm relations with Russia have not strengthened the EU's position in its gas relationship with Russia. Besides, the Lisbon Treaty increases France's and Germany's powers inside the EU. Combined with the conflicting interests of the EU nd Russia, the structure of European politics, and different views

    This study examined the interplay of anti-immigrant prejudice and intergroup contact experience on voting intentions within Britain's 2016 referendum on its membership in the European Union. In the days before the referendum, we asked more than 400 British people how they planned to vote. We measured a number of demographic factors expected to predict voting intentions as well as individuals' prejudice towards and intergroup contact experience (positive and negative) with EU immigrants. Anti-immigrant prejudice was a strong correlate of support for Brexit. Negative intergroup contact experience was associated with higher anti-immigrant prejudice and, in turn, increased support for 'Leave'. Positive intergroup contact, on the other hand, seemed to play a reparative role, predicting lower prejudice and increasing support for 'Remain'. © 2017 The British Psychological Society.

    2017-11-01

    A new borate solid solution series of powders, Li6Eu1-xSmx(BO3)3 (LSEBx, x = 0.35, 0.5, 0.6, 1), were synthesized by solid-state reaction, characterized and their luminescent properties were investigated. The absorption spectra indicate that absorption takes place mainly from the Sm3+6H5/2 ground state, with a strong band at 405 nm. The photoluminescence spectra reveal that the Eu3+ red emission intensity strongly depends on the Sm3+ content x. Judd-Ofelt theory was applied to experimental data for the quantitative determination of phenomenological parameters Ωi (i = 2, 4, 6) Judd Ofelt parameters, radiative transition rates and emission quantum efficiency. Owing to the energy transfer from Sm3+ to Eu3+ the intense red light detected at 613 nm at room temperature under UV or blue light excitation, was improved by ∼35% as compared with Sm3+-free samples. This energy transfer was confirmed by faster decay times of Sm3+ as energy donors. Moreover, the energy transfer between Sm3+ and Eu3+ is unidirectional and irreversible, implying that the energy transfer wastage between Sm3+ and Eu3+ is very low. Magnetic susceptibility (χ) measurements of LSEBx were carried out in the temperature range 2-320 K and are used to compare calculated and experimental energy levels.

  4. Tendances Carbone no. 66 'Understanding the link between macro-economic environment and the EU carbon price'

    International Nuclear Information System (INIS)

    Chevallier, Julien

    2012-01-01

    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 reaction of the carbon price to changes in macro-economic fundamentals can be understood from different levels. My recent academic research has identified two strong linkages. First, there is a link between the EU carbon price and financial markets, such as equity and bond markets. These analyses emphasize how the volatility of the carbon price is affected when financial markets enter 'bull' or 'bear' periods. By estimating various volatility models, carbon futures prices may be weakly forecasted on the basis of two variables from the stock and bond markets, i.e equity dividend yields (returns on stocks) and the 'junk bond' premium (spread between BAA- and AAA-rated bonds). Moreover, by assessing the transmission of international shocks to the carbon market, carbon prices tend to respond negatively to an exogenous recessionary shock on global economic indicators. In consequence, for investments managers, carbon assets such as EUA appear to be well-suited for portfolio diversification since they do not match exactly the business cycle. The second relationship addresses the physical association between industrial production and carbon price changes though the emissions level. The first objective of an academic researcher is to identify the most explanatory variable: in our case, the monthly Eurostat aggregated industrial production index to proxy for changes in macro-economic fundamentals. In the light of the recent periods of economic expansion (2005-2007) and recession (since 2008), several studies can bring fruitful results: - Our results tend to confirm that the carbon market adjusts to the macro-economic environment with a delay due to the specific institutional constraints of the EU ETS. - The relationship between carbon prices and EU industrial production has

  15. The paradox of EU enlargement and member states' policies: Dilemmas and challenges: The case of Portugal

    Directory of Open Access Journals (Sweden)

    Full Text Available The paper addresses the issue of EU enlargement with its dual nature: of an intra-EU process, related to the consolidation of a democratic-peace based on collective security, and an external process, involving EU foreign policy and impact on relations with other major global players. Although enlargement is a multidimensional process that combines different perspectives - candidate countries' enlargement politics, member states' politics/policy, EU enlargement politics and external global impact - the paper focuses on Member States policies towards enlargement by looking at the case of Portugal, in particular in relation with the Big Bang Eastern enlargement, and aims at explaining the paradox of Portugal's strong political support to enlargement while it was one of the main potential losers in terms of economic interests. A 'foreign policy analysis' framework is adopted in order to understand the process of decision-making and the interaction between the domestic and the EU levels. The argument put forward is that an exclusive constructivist approach does not provide a satisfactory explanation, as there was also rationalist-interest logic at play. The Portuguese policy towards enlargement was determined not only by the 'solidaritysimilarity' logic, dominant in the formal political discourse but also by the consideration of long-term interests in the EU related to the preservation of the strategic alliance with Germany. The overall systemic impact of enlargement tends to weaken the EU as it presents a major paradox functioning as a double-edged sword. While it has a positive impact by contributing to the enhancement of the EU international profile as it grows in size raising expectations about its potential global role, it also leads to greater heterogeneity, undermining the EU cohesion and its ability to act together with a single voice becoming a robust global player, thus frustrating the expectations raised in the first place.

    Spherical SiO2 particles having a LaBO3:Eu3+ shell have been prepared by coating of silica nanoparticles (size around 130-150 nm) with a LaBO3:Eu3+ sol-gel precursor and subsequent calcination. The SiO2@LaBO3:Eu3+ nanoparticles were characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy, and transmission electron microscopy. The XRD and FTIR results revealed that the LaBO3:Eu3+ layer on SiO2 nanoparticles formed an H-LaBO3 crystal phase when calcination at a temperature up to 700 °C. Both excitation and emission properties were characterized. The strong excitation lines at 393 and 465 nm of SiO2@LaBO3:Eu3+ indicated that the core-shell phosphor matched well with the output wavelength of near-UV (350-400 nm) or blue LED (450 nm) chips in phosphor-converted W-LEDs. The emission spectra of the 5D0 → 7F J ( J = 0, 1, 2, 3, and 4) transitions at blue/near-UV light showed strong emission lines around 615 nm which were attributed to the induced electric dipole transition of 5D0 → 7F2. The coating cycles affected the luminescence of SiO2@LaBO3:Eu3+ nanoparticles and their CIE chromaticity coordinate shifted from orange-red to the deep red zone with the increase in the coating cycles (up to 3). The luminescence lifetime of the Eu3+ ions in SiO2@LaBO3:Eu3+ was 2.32 ms. Such a luminescent material may be useful for display and light applications.

    In this work, we investigate the efficient energy transfer occurring between ZnO nanocrystals (ZnO-nc) and europium (Eu(3+)) ions embedded in a SiO2 matrix prepared using the sol-gel technique. We show that a strong red emission was observed at 614 nm when the ZnO-nc were excited using a continuous optical excitation at 325 nm. This emission is due to the radiative (5)D0 → (7)F2 de-excitation of the Eu(3+) ions and has been conclusively shown to be due to the energy transfer from the excited ZnO-nc to the Eu(3+) ions. The photoluminescence excitation spectra are also examined in this work to confirm the energy transfer from ZnO-nc to the Eu(3+) ions. Furthermore, we study various de-excitation processes from the excited ZnO-nc and their contribution to the energy transfer to Eu(3+) ions. We also report the optimum fabrication process for maximum red emission at 614 nm from the samples where we show a strong dependence on the annealing temperature and the Eu(3+) concentration in the sample. The maximum red emission is observed with 12 mol% Eu(3+) annealed at 450 °C. This work provides a better understanding of the energy transfer mechanism from ZnO-nc to Eu(3+) ions and is important for applications in photonics, especially for light emitting devices.

    Full Text Available The European Community Humanitarian Office (ECHO and the 15 membercountries of the EU provide more than 50% of the humanitarian aid worldwide: ECHO assigns more than 90% of its budget (only 0.9% of the Community’s total to victims of man-made conflicts. For the author, the experience of ECHO shows the "limits of what is humanitarian": that is, the lack of security for humanitarian workers, the still-to-beoperational Permanent Tribunal for Crimes Against Humanity, the difficult access to refugees, and the fact that humanitarian efforts are not a substitute for policy and, therefore, that humanitarian efforts can not resolve a crisis that has a political origin and solution. The challenges to be faced in the coming years include denouncing the violations of humanitarian values, transferring these values into a future CFSP, organizing humanitarian aid efficiently, combating “donor fatigue” and supporting conflict prevention.

    Isenberg, James

    2017-01-01

    The Hawking-Penrose theorems tell us that solutions of Einstein's equations are generally singular, in the sense of the incompleteness of causal geodesics (the paths of physical observers). These singularities might be marked by the blowup of curvature and therefore crushing tidal forces, or by the breakdown of physical determinism. Penrose has conjectured (in his `Strong Cosmic Censorship Conjecture`) that it is generically unbounded curvature that causes singularities, rather than causal breakdown. The verification that ``AVTD behavior'' (marked by the domination of time derivatives over space derivatives) is generically present in a family of solutions has proven to be a useful tool for studying model versions of Strong Cosmic Censorship in that family. I discuss some of the history of Strong Cosmic Censorship, and then discuss what is known about AVTD behavior and Strong Cosmic Censorship in families of solutions defined by varying degrees of isometry, and discuss recent results which we believe will extend this knowledge and provide new support for Strong Cosmic Censorship. I also comment on some of the recent work on ``Weak Null Singularities'', and how this relates to Strong Cosmic Censorship.

    Pervoskite manganite EuMnO3 synthesized by solid-state route was studied for their structural and magnetocaloric properties. EuMnO3 formed a single phase compound in orthorhombic crystal structure with a space group of Pbnm. The zero field cooling and field cooling magnetic responses exhibit an optimal Neel temperature (TN) of 57 K. A stronger magnetic coupling between the EuMnO3 particles are observed by a delay in reaching TN. The magnetocaloric effect analyzed extensively from the negative entropy (‑ΔSm) change of 15.23 JKg‑1K‑1 for EuMnO3, exhibited a Relative Cooling Power (RCP) of ∼211 JKg‑1 at 1.2 T proposing EuMnO3 as a potential magnetic refrigerant.

  3. EU Integration and Harmonisation of Personal Income Taxation

    Directory of Open Access Journals (Sweden)

    Tomasz Wołowiec

    2011-03-01

    Full Text Available In the process of furthering EU integration little attention was given to the role of income taxes. Multiple income tax systems exist across the Union and their differentiation negatively impacts the European labour market, investments and savings, inhibiting economic growth. Individual nations have little motivation to harmonise as they can engage in tax rate competition and income taxes are interwoven with social security systems that make any attempts at reform extremely complex and politically unpopular. Much of current harmonisation is “silent”, paralegal, and occurs in response to market forces rather than following a formal plan and through intergovernmental cooperation.

  4. EU, Eastern Europe and Values Imperialism

    Directory of Open Access Journals (Sweden)

    Stephen White

    2014-01-01

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

  5. Normative power Europe? EU relations with Moldova

    Tessa de Wekker

    2010-10-01

    Full Text Available This article analyses the extent to which the European Union (EU constitutes a normative power in its relations with Moldova. ‘Normative power Europe’ is examined along three dimensions: (i normative intent; (ii normative process; and (iii normative impact. Our empirical analysis focuses on two norms: democracy and good governance. In addition, we ask how ‘normatively’ the EU has acted regarding a solution to the Transnistrian conflict. On the basis of our three-dimensional framework, we find that EU normative power can be judged as only moderate in EU-Moldovan relations. As for intent, while norms of democracy and good governance seem to play a central role in EU-Moldovan relations, the Union tends to apply double standards in terms of what it expects from (EU Member States and what it asks of Moldova, and also seems to be inconsistent in its policies towards Moldova and Ukraine. In terms of process, the degree of inclusiveness on the part of the Union has not been satisfactory. Neither has the extent of reflexivity, but more recently the Commission seems to have developed a more reflexive behaviour. In regards to impact, while norm changes in Moldova have been modest/moderate, it seems that the EU has substantially contributed to these changes.

  6. EU Security of Gas Supplies: Solidarity Runs Through the Pipeline

    Aoun, Marie-Claire; Rutten, Daan

    2016-05-01

    The ongoing efforts to lessen the European Union's (EU) vulnerability to gas shortages by adopting internal measures were triggered by the Ukrainian gas disputes of 2006 and 2009. The latter deprived several EU Member States of 20% of their gas supplies (30% of imports) for 14 days in the middle of winter due to tensions with Russia. This prompted Member States in 2010 to adopt a Regulation for the Security of Gas Supply, replacing the skeletal 2004 Directive. Since 2014, tensions have increased significantly between the EU and Russia, the block's main gas supplier. Although this has not led to any gas supply disruptions in Europe, and this time Ukraine has been able to revert to reverse flows, national production and storage withdrawals to replace the Russian gas flows, there remains a perceived elevated risk of gas supply disruptions to the EU, especially by certain Member States. This led the European Commission (EC) to publish its first-ever European Energy Security Strategy in May 2014, which was followed by the Gas Stress Tests of October 2014. In February 2015, the EC published its Energy Union Strategy Framework, which was strongly motivated by energy security concerns. In that context, the EC announced a series of proposals for its gas and electricity markets in 2016 and 2017, among which was the 'Sustainable Energy Security Package' (hereafter: Package). This Package, published in February 2016, consists of four proposals. Two of them have a legislative nature, namely a Regulation for Security of Gas Supply and a Decision on Intergovernmental Agreements on energy. The two non-legislative proposals are strategy papers dealing respectively with LNG and Gas Storage, and Heating and Cooling. The purpose of this paper is to focus on the proposed Regulation and to offer considerations on some of its provisions, in particular on the move from the national to the regional level of cooperation and on the legislative formalization of solidarity

    We present β -detected NMR measurements of the spin-lattice relaxation of +8Li implanted into an epitaxial heterostructure based on a 100 nm thick film of ferromagnetic (FM) EuO as a function of temperature through its FM transition. In the FM state, the spin-lattice relaxation rate follows the same temperature dependence, determined by magnon scattering mechanisms, observed in the bulk by 153Eu NMR, but above 40 K, the signal is wiped out. We also find that +8Li stopped in material adjacent to the magnetic layer exhibits spin relaxation related to the critical slowing of the Eu spins. A particularly strong relaxation in the Au overlayer suggests an unusual strong nonlocal coupling mechanism to 8Li in the metal.

  8. Tests for removal of Co-60 and Eu-154 from irradiated graphite in the TRIGA Reactor

    2009-01-01

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

  9. Post-accession compliance with EU gender equality legislation in post-communist new member states

    Ulrich Sedelmeier

    2009-12-01

    Full Text Available This paper analyses the transposition of EU legislation on gender equality at the workplace in the Czech Republic, Hungary, Lithuania and Slovenia, as well as the enforcement powers of their national equality institutions. It does not find significant differences between post- and pre-accession compliance. Overall compliance can be considered good in Hungary, Lithuania, and Slovenia, while it is considerably worse in the Czech Republic – both pre- and post-accession. As an explanation for these variations in legal transposition and enforcement bodies, the paper finds two equifinal paths towards correct transposition of EU gender equality legislation and strong enforcement bodies: either the absence of high adjustment costs, or the combination of strong social democratic governments and NGOs with special expertise in EU gender equality legislation.

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

    International Nuclear Information System (INIS)

    Prange-Gstoehl, Heiko

    2009-01-01

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

The Eu{sup 3+} → Eu{sup 2+} reduction was monitored analyzing XANES region when the sample are excited at the Eu L{sub III}-edge. The results show that the hydrogen reducing agent are the most appropriate gas for Eu{sup 2+} stabilization in BaAl{sub 2}O{sub 4} and that only a part of the Eu ions can be stabilized in the divalent state. A model of Eu reduction process, based on the incorporation of charge compensation defects, is proposed.

    2017-03-01

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

    Luminescence properties of divalent europium in the mixed-anion hydride chloride EuHCl were studied for the first time. Olive-green single crystals of EuHCl (PbFCl-type structure: tetragonal, P4/nmm, a = 406.58(3) pm, c = 693.12(5) pm, c/a = 1.705, Z = 2) resulted from the reaction of elemental europium (Eu), sodium hydride (NaH) and sodium chloride (NaCl), while powder samples were prepared from the binary components europium dihydride (EuH 2 ) and dichloride (EuCl 2 ). Low temperature X-ray powder diffraction proved the absence of phase transitions for 12(2) K ≤ T ≤ 295(2) K. Bright green emission was observed under UV-excitation and assigned to the 4f 6 5d 1 -4f 7 transition of divalent europium. Temperature-dependent luminescence absorption and emission, as well as lifetime measurements were carried out on single crystal and powder samples. Surprisingly, only limited concentration quenching was found. Additionally, two emission bands (485 and 510 nm) are observed, whose intensity ratio depends strongly on temperature. In order to explain this behavior for a single Eu 2+ site, we suggest either a dynamical Jahn-Teller effect in the excited 5d 1 state or emission from both a 4f 6 5d 1 state and a trapped exciton state.

    Full Text Available The Eastern Partnership (2009 as a component part of the European Neighbourhood Policy is a tool that aims at the economic integration and political cooperation of the countries that are included in this project by signing association and free trade agreements with the European Union (EU. The recent events in Ukraine have revealed the possibility of these countries to become EU member states depending on the progress made, which is confirmed by many European experts. However, there are big differences among the Eastern Partnership countries on their way to EU integration on the background of the strong pressure from Russia, aimed to suppress any pro-European manifestations of such countries. Despite the sharpening of geopolitical challenges, the EU continues to use the traditional ways of enlargement and deepening of cooperation processes with the Eastern Neighbourhood. This paper aims at reviewing the theoretical approaches through which the EU, as a normative power, exerts major influence on the Eastern Partnership (EaP countries by extending the neofunctional practices, intergovernmental cooperation and the constructivist model. However, in view of reaching the soft power objectives, we aim at transforming and strengthening the EU positions in the context of amplified economic and political-ideological problems at regional level.

    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.

    Full Text Available Highly luminescent nanophosphors (NPs containing rare earth (RE ions were successfully prepared by careful control of nanosynthesis. The YVO4:Eu3+ NPs formed core/shell structures with sizes from 10 nm to 25 nm. The NPs were functionalized with biocompatible groups such as OH, NH2 and SCN. A chemical coupling reaction connected the functionalized YVO4:Eu3+ NPs with Biotin via a direct reaction between the functional groups or an intermediate linker. Under UVIS excitation, YVO4:Eu3+ NPs exhibited strong red luminescence with narrow bands corresponding to the intra 4f transitions of D05–Fj7 (j = 1, 2, 3, 4 Eu3+. The peaks were found at 594 nm (D05–F17, 619 nm (D05–F27, 652 nm (D05–F37 and 702 nm (D05–F47 with the strongest emission at 619 nm. The fluorescence intensity and stability of the functionalized YVO4:Eu3+ NPs have been increased. This is a promising result in sense of using the conjugates of YVO4:Eu3+ and a bioactive molecule, Biotin for the development of a fluorescent label tool in biomedical analysis.

  3. Inconsistencies in data requirements of EU legislation involving tests on animals.

    European Union (EU) legislation on the protection of animals used for scientific purposes requires that alternative methods must be used instead of animal tests wherever they are available. Unfortunately, this provision is not implemented to its full extent when it comes to risk assessment of chemicals and new products prior to their authorization and placing on the market in the EU. In this study, we screened data requirements of relevant EU law regarding chemicals (REACH), biocides, pesticides, and food safety (Novel Food) and found that data requirements as part of the risk assessment do not always reflect state-of-the-art science and technology. Most of the data requirements we investigated still include testing on animals for many toxicological endpoints, even though more than 40 alternative testing methods accepted at the level of the EU or the OECD are available. This may be due to a multitude of reasons, including a shortage of both manpower to implement existing knowledge and expertise in the field of alternative methods, as well as unclear and misleading statements on the applicability and state of validation of alternative methods. In conclusion, we strongly suggest a homogeneous EU-wide approach for all areas involving risk assessment of substances with the goal of better implementing the 3Rs and complying with Directive 2010/63/EU. This also would streamline data requirements, save costs on various levels, and enhance product safety for consumers.

    Europium single doped potassium lutetium tungstate Eu 3+ :KLu(WO 4 ) 2 single crystals have been grown with the top seeded solution growth slow cooling method. Their absorption spectra are studied in detail for principal light polarizations, E||N p , N m and N g at room and low temperatures. The absorption oscillator strengths parameters are calculated by means of the theory of f–f transition intensities for systems with anomalously strong configuration interaction and by Judd–Ofelt theory. The Ω t (t=2, 4, 6) intensity parameters, and the {O dk , O ck , Δ d , Δ c1 and Δ c2 } (k=1, 2, 3) ASCI parameters are calculated. The radiative transition rates A R , radiative lifetimes τ R , and fluorescent branching ratios β R associated with 5 D 0 – 7 F J transitions of Eu 3+ were determined. The calculated decay times are discussed and compared with experimental values. - Highlights: • Absorption spectra of Eu:KLuW are investigated with respect to principal light polarizations. • Spectroscopic properties of Eu:KLuW are modeled within conventional Judd–Ofelt and (ASCI) theories. • 5 D 0 multiplet shows the contribution of a NR processes and an ET between the Eu 3+ ions. • It is suggested that the Eu 3+ :KLuW is a potential host material for optical applications.

    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.

    2014-04-01

    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.

    Gd2O3:Eu3+ and Y2O3:Eu3+ nanophosphors have been successfully fabricated by a combustion method at low temperature (350°C) in a short time (5 min) using natriethylenediaminetetraacetic acid (EDTA-Na2) as fuel. The structure, morphology and size of Gd2O3:Eu3+ and Y2O3:Eu3+ nanophosphors have been determined by x-ray diffraction and field emission scanning electron microscopy. Photoluminescence spectra indicated that the optimum Eu3+ ion concentrations with the strongest luminescence emission intensities are 5 mol.% for Y2O3:Eu3+ and 7 mol.% for Gd2O3:Eu3+. The nanocomposites of Gd2O3:Eu3+/silica and Y2O3:Eu3+/silica were fabricated by a sol-gel process with tetraethoxysilane (TEOS) as matrix material, and the nanocomposite compositions were analyzed by energy dispersion spectra. The strongest luminescence peaks from the 5D0-7F2 transition of the Eu3+ ion in Gd2O3:Eu3+ and Y2O3:Eu3+ nanophosphors are between 613 nm and 615 nm. The Gd2O3:Eu3+ and Y2O3:Eu3+ nanophosphors and their silica nanocomposites were studied to elucidate the influences of the Eu3+ concentration, host materials, annealing temperature, and weight ratio of TEOS and Gd2O3:Eu3+ or Y2O3:Eu3+.

    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.

    Full Text Available ZnO doped with Eu3+ and Tb3+ had been successfully prepared by wet chemical method with the assistance of microwave. The influence of reaction conditions such as temperature, time, content of Eu3+, Tb3+ ion, and annealing treatment on the structure and luminescent characteristics was studied. The analysis of energy dispersive spectroscopy (EDS and photoluminescence spectra measurements indicated that Eu3+ and Tb3+ exist in host lattice and create the new emission region compared to ZnO crystalline host lattice. The field emission scanning electron microscope (FE-SEM studies show the Eu3+, Tb3+ doped ZnO nanoparticles have a pseudohexagonal shape. The particle size was 30–50 nm for ZnO:Eu3+ and 40–60 nm for ZnO:Tb3+. Photoluminescence excitation (PLE and photoluminescence (PL spectra at room temperature have been studied to recognize active centers for characteristic luminescence of ZnO:Eu3+ and ZnO:Tb3+. The characteristic luminescent lines of Eu3+ (5D0-7Fj and Tb3+ (5D4-7Fj were determined. It has been demonstrated that the wet chemical synthesis method with microwave assistance can strongly enhance the luminescent intensity of nanoparticles ZnO:Eu3+ in red and ZnO:Tb3+ in green.

    Directory of Open Access Journals (Sweden)

    Abdul Kareem Parchur

    2012-09-01

    Full Text Available This article explores the tuning of blue to pink colour generation from Li+ ion co-doped YPO4:5Eu nanoparticles prepared by polyol method at ∼100-120 °C with ethylene glycol (EG as a capping agent. Interaction of EG molecules capped on the surface of the nanoparticles and/or created oxygen vacancies induces formation of intermediate/mid gap bands in the host structure, which is supported by UV-Visible absorption data. Strong blue and pink colors can be observed in the cases of as-prepared and 500 °C annealed samples, respectively. Co-doping of Li+ enhances the emission intensities of intermediate band as well as Eu3+. On annealing as-prepared sample to 500 °C, the intermediate band emission intensity decreases, whereas Eu3+ emission intensity increases suggesting increase of extent of energy transfer from the intermediate band to Eu3+ on annealing. Emission intensity ratio of electric to magnetic dipole transitions of Eu3+ can be varied by changing excitation wavelength. The X-ray photoelectron spectroscopy (XPS study of as-prepared samples confirms the presence of oxygen vacancies and Eu3+ but absence of Eu2+. Dispersed particles in ethanol and polymer film show the strong blue color, suggesting that these materials will be useful as probes in life science and also in light emitting device applications.

    2015-01-01

    Piezoelectrically-induced stress-luminescence in the CaAl 2 O 4 :Eu 2+ was investigated. Blue light that was visible to the naked eye could be observed in the dark when a pulse force of ∼7.7 kN was applied to the sample. The intensity of the stress-luminescence strongly depended on the magnitude of the applied force during a pulse cycle. The intensity decreased with repetitive application of pulse stress and was completely recovered after irradiation with ultraviolet light. It is suggested that the stress-luminescence effect in CaAl 2 O 4 :Eu 2+ arises from the piezoelectrically-induced de-trapping of the charge carriers. A CaAl 2 O 4 :Eu 2+ ceramic that exhibits a stress-luminescence effect has potential applications in smart stress optically-sensing devices. - Highlights: • The strong induced stress-luminescence in CaAl 2 O 4 :Eu 2+ was observed. • The stress-luminescent intensity strongly depends on the magnitude of force. • The stress-luminescence could be completely recovered after the UV irradiation. • The strong stress-luminescent effect is potential in stress-light sensors

  1. Taxing of financial sector as possible own resource of EU budget

    Directory of Open Access Journals (Sweden)

    Danuše Nerudová

    2013-01-01

    Full Text Available The discussion about the possible taxation of the financial sector has started in the European Union as a result of the financial crisis which has spread to the Europe from the United States in 2008. European Commission concluded that EU should lead the efforts to introduce system of levies or taxies on financial institutions. EU member states individually committed to support the financial sector for a total about EUR 4.6 trillion (i.e. 39% of EU-27 GDP in 2009. Those public interventions have significant budgetary consequences (strongly felt in Greece, Spain or Italy and imposes a heavy burden on the present and future generations. Therefore there is a strong consensus not only on the level of the European Union but also internationally, that financial sector should contribute to the public finance more fairly. As a reaction on costs of the financial crisis which was paid out from the public money, some of the countries immediately introduced temporary measures in order to collect back paid out money. The aim of the paper is to research the possibility of financial sector taxation, to discuss the proposal of the European Union on the introduction of financial transaction tax on EU level and through the multi-criteria analysis to research, whether this type of the tax is suitable as an own resource of EU budget.

  2. Strong Electroweak Symmetry Breaking

    CERN Document Server

    Grinstein, Benjamin

    2011-01-01

    Models of spontaneous breaking of electroweak symmetry by a strong interaction do not have fine tuning/hierarchy problem. They are conceptually elegant and use the only mechanism of spontaneous breaking of a gauge symmetry that is known to occur in nature. The simplest model, minimal technicolor with extended technicolor interactions, is appealing because one can calculate by scaling up from QCD. But it is ruled out on many counts: inappropriately low quark and lepton masses (or excessive FCNC), bad electroweak data fits, light scalar and vector states, etc. However, nature may not choose the minimal model and then we are stuck: except possibly through lattice simulations, we are unable to compute and test the models. In the LHC era it therefore makes sense to abandon specific models (of strong EW breaking) and concentrate on generic features that may indicate discovery. The Technicolor Straw Man is not a model but a parametrized search strategy inspired by a remarkable generic feature of walking technicolor,...

  3. 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.

  4. IAEA-EU Joint Action Partnership in Improving Nuclear Security

    International Nuclear Information System (INIS)

    2011-12-01

    Nuclear and other radioactive material is on the move and in demand. Used in peaceful applications such as energy, medicine, research and industry, it improves the daily lives of individuals worldwide. Nonetheless, the risk posed by it falling into the wrong hands is a real and growing concern of the international community and one that demands improved nuclear security. Steps to bolster nuclear security and mitigate this risk include accounting for and securing nuclear and radioactive material as well as their related facilities, and helping to prevent theft, sabotage and use with malicious intent. Strong legislative, regulatory and enforcement frameworks, enhanced national capacity, and increased international cooperation in protecting against, and preparing for, any scenario strengthens these measures further. As a result, the Board of Governors of the International Atomic Energy Agency (IAEA) approved a plan of activities in 2002 to improve nuclear security worldwide. In 2003, the Council of the European Union (EU) adopted its Strategy against Proliferation of Weapons of Mass Destruction. Since then, five Contribution Agreements between the European Commission (EC) and the IAEA have been undertaken to provide financial support to IAEA activities in the areas of nuclear security and verification. These 'Joint Actions' assist States in strengthening their nuclear security infrastructure and underscore both the EU and IAEA's commitment to effective cooperation. IAEA-EU JOINT ACTION. The IAEA works to improve and strengthen national nuclear security programmes worldwide. EU support helps to advance the IAEA's efforts by raising awareness and improving understanding of nuclear security and its many component parts. Priority is given to those States that need to determine what radioactive and nuclear material they have, how to control it and how to reduce the risk it poses. Efforts focus on three main areas, strengthening: (i) States' legislative and regulatory

  7. Plasmons in strong superconductors

    International Nuclear Information System (INIS)

    Baldo, M.; Ducoin, C.

    2011-01-01

    We present a study of the possible plasmon excitations that can occur in systems where strong superconductivity is present. In these systems the plasmon energy is comparable to or smaller than the pairing gap. As a prototype of these systems we consider the proton component of Neutron Star matter just below the crust when electron screening is not taken into account. For the realistic case we consider in detail the different aspects of the elementary excitations when the proton, electron components are considered within the Random-Phase Approximation generalized to the superfluid case, while the influence of the neutron component is considered only at qualitative level. Electron screening plays a major role in modifying the proton spectrum and spectral function. At the same time the electron plasmon is strongly modified and damped by the indirect coupling with the superfluid proton component, even at moderately low values of the gap. The excitation spectrum shows the interplay of the different components and their relevance for each excitation modes. The results are relevant for neutrino physics and thermodynamical processes in neutron stars. If electron screening is neglected, the spectral properties of the proton component show some resemblance with the physical situation in high-T c superconductors, and we briefly discuss similarities and differences in this connection. In a general prospect, the results of the study emphasize the role of Coulomb interaction in strong superconductors.

    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 European Conference ‘Patient Safety – Making it happen!’ took place in Luxembourg under the auspices of the Luxembourg EU presidency and EU Commissioner Kyprianou and resulted in the “Luxembourg Declaration on Patient Safety”.

    This Declaration contains recommendations to the EU, national authorities and healthcare organizations. It underlines the added value of the EU and recommends joining forces with the WHO Alliance for Patient Safety.

    A culture of transparency, trust and safety is being sought for through the suggested use of e-health, flows of health information, patient involvement and reporting systems. CPME saw perseverance and commitment pay off as patient safety is now seen as a priority by all health stakeholders and EU institutional bodies (European Commission, presidencies and Council. However all parties realise full well that the Luxembourg Declaration on Patient Safety is only the first step. All efforts are now focussed on follow up and implementation.

    The interaction of calcite with trivalent europium under recrystallization conditions was studied on the molecular level using site-selective time-resolved laser fluorescence spectroscopy (TRLFS). We conducted batch studies with a reaction time from seven days up to three years with three calcite powders, which differed in their specific surface area, recrystallization rates and impurities content. With increase of the recrystallization rate incorporation of Eu(3+) occurs faster and its speciation comes to be dominated by one species with its excitation maximum at 578.8 nm, so far not identified during previous investigations of this process under growth and phase transformation conditions. A long lifetime of 3750 μs demonstrates complete loss of hydration, consequently Eu must have been incorporated into the bulk crystal. The results show a strong dependence of the incorporation kinetics on the recrystallization rate of the different calcites. Furthermore the investigation of the effect of different background electrolytes (NaCl and KCl) demonstrate that the incorporation process under recrystallization conditions strongly depends on the availability of Na(+). These findings emphasize the different retention potential of calcite as a primary and secondary mineral e.g. in a nuclear waste disposal site.

  15. Strong-coupling approximations

    Standard path-integral techniques such as instanton calculations give good answers for weak-coupling problems, but become unreliable for strong-coupling. Here we consider a method of replacing the original potential by a suitably chosen harmonic oscillator potential. Physically this is motivated by the fact that potential barriers below the level of the ground-state energy of a quantum-mechanical system have little effect. Numerically, results are good, both for quantum-mechanical problems and for massive phi 4 field theory in 1 + 1 dimensions. 9 references, 6 figures

    With an assumed weak multiplet structure for bosonic hadrons, which is consistent with the ΔI = 1/2 rule, it is shown that the strong interaction effective hamiltonian is compatible with the weak SU(2) x U(1) gauge transformation. Especially the rho-meson transforms as a triplet under SU(2)sub(w), and this is the origin of the rho-photon analogy. It is also shown that the existence of the non-vanishing Cabibbo angle is a necessary condition for the absence of the exotic hadrons. (orig.)

    2016-12-01

    A comparative μSR study of ceramic samples of the EuMn2O5 and Eu0.8Ce0.2Mn2O5 multiferroics is performed in the temperature range from 15 to 300 K. It is found that the Ce doping of the EuMn2O5 sample slightly reduces the temperature of the magnetic phase transition from T N = 45 K for the EuMn2O5 sample to T N = 42.5 K for the Eu0.8Ce0.2Mn2O5 sample. Below the temperature T N for both samples, there are two types of localization of a thermalized muon with different temperature dependences of the precession frequency of the magnetic moment of the muon in an internal magnetic field. The higher frequency in both samples refers to the initial antiferromagnetic matrix. The behavior of this frequency in Eu0.8Ce0.2Mn2O5 follows the Curie-Weiss law with the exponent β = 0.29 ± 0.02, which differs from the value β = 0.39 standard for 3D Heisenberg magnetics and is observed in EuMn2O5, because of the strong frustration of the doped sample. The temperature-independent low frequency is due to the presence of Mn3+-Mn4+ ferromagnetic pairs located along the b axis of the antiferromagnetic matrix and in the regions of phase separation, which contain such ion pairs and e g electrons recharging them. In both samples, polarization losses are the same (about 20%) and are associated with the formation of Mn4+-Mn4+ + Mu complexes near Mn3+-Mn4+ ferromagnetic pairs. In the temperature interval from 25 to 45 K, the separation of the Eu0.8Ce0.2Mn2O5 structure into two fractions where the relaxation rates of polarization of muons differ by an order of magnitude is revealed. This effect is due to a change in the state of regions of phase separation (1D superlattices) at the indicated temperatures. Such effect in EuMn2O5 is significantly weaker.

  20. Strong Coupling Holography

    2009-01-01

    We show that whenever a 4-dimensional theory with N particle species emerges as a consistent low energy description of a 3-brane embedded in an asymptotically-flat (4+d)-dimensional space, the holographic scale of high-dimensional gravity sets the strong coupling scale of the 4D theory. This connection persists in the limit in which gravity can be consistently decoupled. We demonstrate this effect for orbifold planes, as well as for the solitonic branes and string theoretic D-branes. In all cases the emergence of a 4D strong coupling scale from bulk holography is a persistent phenomenon. The effect turns out to be insensitive even to such extreme deformations of the brane action that seemingly shield 4D theory from the bulk gravity effects. A well understood example of such deformation is given by large 4D Einstein term in the 3-brane action, which is known to suppress the strength of 5D gravity at short distances and change the 5D Newton's law into the four-dimensional one. Nevertheless, we observe that the ...

    We synthesized Eu3+/Tb3+co-doped polymethyl methacrylate (PMMA), and studied the excitation and emission spectra of the sample in detail. Under 332 nm excitation, the sample can emit strong white-light by mixing red, green, and blue emissions. The CIE chromaticity coordinates (X  =  0.355, Y  =  0.346) of the luminescence are close to the standard white-light illumination (0.333, 0.333). Thus, the Eu3+/Tb3+ co-doped PMMA is a valuable luminescent material for white light-emitting diodes.

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

    Electron spin resonance of Eu2+ ( 4f7 , S=7/2 ) in a La hexaboride (LaB6) single crystal shows a single anisotropic Dysonian resonance. From the observed negative g shift of the resonance, it is inferred that the Eu2+ ions are covalent exchange coupled to the B2p -like host conduction electrons. From the anisotropy of the spectra (linewidth and field for resonance), we found that the S ground state of Eu2+ ions experience a cubic crystal field of a negative fourth order crystal field parameter (CFP), b4=-11.5(2.0)Oe , in agreement with the negative fourth order CFP, A4 , found for the non- S ground state R hexaborides. These results support covalency as the dominant contribution to the fourth order CFP for the whole R hexaboride family.

    2015-12-01

    Full Text Available Nowadays, one of the major concerns of the EU leaders is how to cope with the large inflows of refugees that are coming from the Arab region, because of the prolonged conflicts and civil wars. While some EU leaders consider that this is a humanitarian crisis and the member states should act accordingly, others consider that these people are migrants and not refugees. From the economic perspective, the opinions are also divided. Some analysts see this large influx of refugees as an opportunity for the economic and social environment, while others consider that the refugees can negatively influence the well-being of the host countries. In the present paper we investigate the impact of the refugees’ inflows on the economic growth and development of the EU countries. In order to reach this purpose, our arguments are based on a multidisciplinary analysis of the specialised literature and of the empirical investigations.

    Full Text Available In the process of EU integration, the aspiring and potential candidate countries have undergone a major process of reforms. The question that is aroused in this sense is to what extent the EU has had transformative power and impacted the internal judicial structures of Kosovo and under which conditions the EU is more effective. This article analyzes the findings of the Progress reports for a ten-year period (2005 – 2015 and the extent of the EU impact. It uses the conceptual and rational framework of external incentives model and argues that the EU impact in the judiciary system of Kosovo is crucial considering the starting low phase of reforms in Kosovo.

  9. Do supranational EU institutions make a difference? EU asylum law before and after ‘communitarization’

    Ripoll Servent, Ariadna; Trauner, Florian

    2014-01-01

    ABSTRACT This article examines whether the empowerment of the European Union's (EU) supranational institutions has had an impact on the development of EU asylum. By systematically investigating EU asylum law before and after ‘communitarization’, it argues that its ‘policy core’ has maintained a high degree of continuity. An advocacy coalition under the leadership of the interior ministers managed to co-opt pivotal actors in the newly empowered European Commission and European Parliament. By contenting themselves with changes of secondary order, these EU institutions accepted and institutionalized the restrictive and weakly integrated core of EU asylum set by the Council in the first negotiation round. Their role and decisions were driven not only by the negotiation dynamics and political expediency, but also by new inter- and intra-institutional norms fostering consensual practices. PMID:26924934

    2009-04-01

    Full Text Available Following a five-year period of uninterrupted growth and reaching a historical peak in 2007, world foreign direct investment flows (FDI declined in 2008, in large part as a result of the global financial and economic crisis. The European Union (EU as a major source and recipient of FDI flows in the world has been particularly badly hit, reflecting the close economic relationship which exists between the EU and the rest of the world, on the one hand, and among the Member States, on the other hand. The paper analyses the impact of the current crisis on EU's FDI inflows and outflows, in terms of dynamics and volume, as well as the short term and long-term prospects for FDI. Special attention is devoted to disentangling the transmission channels of the crisis, the key features of the FDI downturn and its underlying factors. The empirical investigation relies on UNCTAD data for tracing the evolution of FDI flows at the European level as compared to worldwide trends, while Eurostat data are used to highlight the impact of the crisis on intra-EU FDI flows. Whenever possible, a distinctive analysis is carried out for the old and new EU Member States. The paper is organized around six sections. Its findings reveal, inter alia, that notwithstanding the sharp fall in total FDI flows in 2008, the EU maintains its position as a global leader in terms of FDI flows. However, it will take quite a long time until recovering from the negative effects of the present crisis in terms of investments. Besides, the EU is not likely to be the driving force behind the next wave of FDI surge in the world as this role will be taken over by emerging economies like China, India and Brazilia.

    In order to obtain an interdisciplinary understanding of the world that also includes theology, I believe panentheism, as a potential explanatory model of a God relationship to the world, needs to be revisited. Naturalistic explanations leave out the possible existence of God and hence deprive...... millions of religious believers of a satisfactory explanation. The present paper deals with this neglect.

    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.

    2015-08-01

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

    2009-10-01

    Full Text Available In line with the world economy trend, the collapse in world trade in goods and services observed in the last quarter of 2008 intensified inthe first quarter of 2009, but the trough in growth rates has likely been reached; positive quarterly growth rates are expected by the end of 2009. UE-27 registered the slowest export growth of any region last year, with an expansion of just 0.0per cent, down from 3.5 per cent in 2007. Import growthturned negative in 2008, falling by 1 per cent (+3.5 per cent in 2007. If the 27 members of the European Union are considered collectively(excluding internal EU trade, the five leading exporters were the European Union (15.9 per cent of world exports, China (8.9%, the United States(8.1%, Japan (4.9% and Netherlands (3.9 per cent. Exports from the EU were worth US$ 1.93 trillion in 2008. Signs of recovery are not yet soclearly visible in the EU-27 like in USA, in the last part of 2009. Each country has its own specific combination of weaknesses such as burstinghousing bubbles, declining exports and damaged financial sectors. The eventual recovery is likely to be slow as rising unemployment will hitconsumer spending. In the above mentioned conditions, GDP in the euro area is expected to contract 4.8% in 2009 and to show 0% growth in 2010.The previous projections were for a 4.1% fall in 2009 and a 0.3% fall in 2010. The main factors with a positive influence, taken into consideration forrevising up the projections for 2010 in euro area are: the strengthening growth in world trade which will help support a turnaround in exports, thegovernmental policy support and an easing of financial conditions adopted in some countries.

  15. EU Emission Allowances and the stock market Evidence from the electricity industry

    Oberndorfer, Ulrich

    2009-01-01

    This paper constitutes - to our best knowledge - the first econometric analysis on stock market effects of the EU Emission Trading Scheme (EU ETS). Our results suggest that EU Emission Allowance (EUA) price developments matter to the stock performance of electricity firms: EUA price changes and stock returns of the most important European electricity corporations are shown to be positively related. This effect does not work asymmetrically, so that stock markets do not seem to react differently to EUA appreciations in comparison to depreciations. The carbon market effect is shown to be both time- and country-specific: It is particularly strong for the period of EUA market shock in early 2006, and differs with respect to the countries where the electricity corporations analysed are headquartered. Stock market reactions to EUA volatility could not be shown. (author)

    2016-01-01

    This article discusses Habermas’ vision of a supranational yet democratic EU. The article engages in a discussion of what I take to be two problematic elements of Habermas’ model of EU democracy. Firstly, it discusses the European Parliament as a representative channel, which should, according...... to Habermas, be strengthened. I here raise the concern that Habermas is not sufficiently sensitive to the tension between the recognition of a weak public and the desire for a strong Parliament. Secondly, I discuss whether executive federalism can also be circumvented by strengthening not just...... the representation of the European citizens, but also by strengthening parliamentarian representation of the European peoples. Based on these two critiques I end up arguing that Habermas’ vision for EU democracy would benefit from drawing inspiration from the demoicracy literature’s focus on alternative channels...

  17. Some New Insights into Trade Potential between the EU and Its Mediterranean Partners

    Directory of Open Access Journals (Sweden)

    Nicolas Péridy

    2012-01-01

    Full Text Available This paper provides new insights into the calculation of trade potential between the EU and its Southern and Eastern Mediterranean partners (MPs. It is based on an econometric specification which takes into account some new explanatory variables which are not included simultaneously in the previous studies. These include trade costs (tariffs, NTBs, and logistics costs, factor movement (migration and FDI, as well as governance. In addition, specific estimators are implemented in order to account for zero trade flows, endogeneity and dynamics. The main conclusion of this study is that contrary to some results found in previous studies, MPs have reached their export potential with the EU. It is also shown that there is no specificity of the MP-EU trade potential in comparison with the other main PTAs (NAFTA, MERCOSUR, and ASEAN which have also reached their trade potential. These results have strong policy implications.

    Optical, scintillation properties, optical stimulated luminescence, and thermally stimulated luminescence of Ce 1, 3, and 5% doped and Eu 1, 1.5, and 2% doped LiCaAlF 6 crystals fabricated by Tokuyama Corp. were investigated. In transmittance, absorption was proportional to dopant concentrations and typical optical quantum yield of Ce and Eu-doped LiCaAlF 6 were 40 and 100%, respectively. Scintillation wavelength and decay time profiles were investigated under X-ray irradiation. Ce 3+ and Eu 2+ 5d-4f luminescence appeared around 300 nm and 370 nm with typical decay time of 40 ns and 1.5 μs, respectively. Optically stimulated luminescence of Ce-doped ones appeared under 405 nm stimulation with detectable intensity while those of Eu doped ones were quite weak. Thermally stimulated luminescence of Ce- and Eu-doped LiCaAlF 6 were enough strong and they exhibited good response function from 1 to 1000 mGy exposure. - Highlights: • Optical, scintillation, OSL, and TSL properties of Ce or Eu differently doped LiCaAlF6 were studied. • PL quantum yield of Ce and Eu doped LiCaAlF6 showed 40% and 100%, respectively. • OSL was observed in Ce-doped LiCaAlF6. • TSL was observed in both material systems and exhibited a good dose response from 1 to 1000 mGy

    The Eu 2+ - and Ce 3+ -doped CaAl 2 S 4 phosphors were comparatively synthesized by conventional solid-state reaction and the evacuated sealed quartz ampoule. The X-ray diffraction (XRD) patterns show that the sample with better crystalline quality was prepared by the evacuated sealed quartz ampoule, resulting in the enhancement of the emission intensity of Eu 2+ ion by a factor of 1.7. The intensive green LEDs were also fabricated by combining CaAl 2 S 4 :Eu 2+ with near-ultraviolet InGaN chips (λ em =395 nm). The dependence of as-fabricated green LEDs on forward-bias currents shows that it presents good chromaticity stability and luminance saturation, indicating that CaAl 2 S 4 :Eu 2+ is a promising green-emitting phosphor for a near-UV InGaN-based LED. In addition, the optical properties of CaAl 2 S 4 :Ce 3+ were systematically investigated by means of diffuse reflectance, photoluminescence excitation and emission, concentrating quenching and the decay curve. - Graphical abstract: The Eu 2+ - and Ce 3+ -doped CaAl 2 S 4 phosphors were comparatively synthesized by two methods. The emission intensity of Eu 2+ ion in sample synthesized by the evacuated sealed quartz ampoule method is by a factor of 1.7 as strong as that of Eu 2+ ion in sample prepared by the conventional solid-state reaction method

    Our friend and colleague John Strong was cruelly taken from us by a brain tumour on Monday 31st July, a few days before his 65th birthday John started his career working with a group from Westfield College, under the leadership of Ted Bellamy. He obtained his PhD and spent the early part of his career on experiments at Rutherford Appleton Laboratory (RAL), but after the early 1970s his research was focussed on experiments in CERN. Over the years he made a number of notable contributions to experiments in CERN: The Omega spectrometer adopted a system John had originally developed for experiments at RAL using vidicon cameras to record the sparks in the spark chambers; He contributed to the success of NA1 and NA7, where he became heavily involved in the electronic trigger systems; He was responsible for the second level trigger system for the ALEPH detector and spent five years leading a team that designed and built the system, which ran for twelve years with only minor interventions. Following ALEPH he tur...

  1. Stirring Strongly Coupled Plasma

    CERN Document Server

    Fadafan, Kazem Bitaghsir; Rajagopal, Krishna; Wiedemann, Urs Achim

    2009-01-01

    We determine the energy it takes to move a test quark along a circle of radius L with angular frequency w through the strongly coupled plasma of N=4 supersymmetric Yang-Mills (SYM) theory. We find that for most values of L and w the energy deposited by stirring the plasma in this way is governed either by the drag force acting on a test quark moving through the plasma in a straight line with speed v=Lw or by the energy radiated by a quark in circular motion in the absence of any plasma, whichever is larger. There is a continuous crossover from the drag-dominated regime to the radiation-dominated regime. In the crossover regime we find evidence for significant destructive interference between energy loss due to drag and that due to radiation as if in vacuum. The rotating quark thus serves as a model system in which the relative strength of, and interplay between, two different mechanisms of parton energy loss is accessible via a controlled classical gravity calculation. We close by speculating on the implicati...

  2. Strong-interaction nonuniversality

    International Nuclear Information System (INIS)

    Volkas, R.R.; Foot, R.; He, X.; Joshi, G.C.

    1989-01-01

    The universal QCD color theory is extended to an SU(3) 1 direct product SU(3) 2 direct product SU(3) 3 gauge theory, where quarks of the ith generation transform as triplets under SU(3)/sub i/ and singlets under the other two factors. The usual color group is then identified with the diagonal subgroup, which remains exact after symmetry breaking. The gauge bosons associated with the 16 broken generators then form two massive octets under ordinary color. The interactions between quarks and these heavy gluonlike particles are explicitly nonuniversal and thus an exploration of their physical implications allows us to shed light on the fundamental issue of strong-interaction universality. Nonuniversality and weak flavor mixing are shown to generate heavy-gluon-induced flavor-changing neutral currents. The phenomenology of these processes is studied, as they provide the major experimental constraint on the extended theory. Three symmetry-breaking scenarios are presented. The first has color breaking occurring at the weak scale, while the second and third divorce the two scales. The third model has the interesting feature of radiatively induced off-diagonal Kobayashi-Maskawa matrix elements

    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.

  7. AN ANALYSIS OF UNEMPLOYMENT IN THE COUNTRIES OF EASTERN AND CENTRAL EUROPE IN THE CONTEXT OF E.U. ADHERING

    Directory of Open Access Journals (Sweden)

    Adrian\tLiviu\tSCUTARIU

    2015-06-01

    Full Text Available Unemployment is a negative phenomenon that manifests itself in any economy with varying degrees of intensity. In this paper we propose to analyze the evolution of unemployment in the EU. There are countries where economic recession was felt more intense and harder recovered from it, such as Greece or Spain. Within the European Union one notes some differences in unemployment between Member States but also in terms of age groups. In the EU youth unemployment rate is approximately double that the general unemployment rate, but the situation is worse in some countries where youth unemployment rate is even higher. Our analysis also focuses on trends recorded at regional level in Central and Eastern Europe countries in the context of their accession to the EU, highlighting positive developments, which were maintained in the coming years. The unemployment rate decrease is one of the objectives followed by the EU through its policies.

    2016-06-01

    Full Text Available Increasing amounts of the EU structural support in Lithuania require theoretical and practical research to disclose the determinants that have a significant impact on the competitiveness of Lithuanian economics. The purpose of this article is to evaluate the impact of the EU structural support on the competitiveness of Lithuanian economics. The methods of the research include systematic and comparative analysis of the scientific literature, expert evaluation and linear regression. The research disclosed the main determinants of country’s competitiveness. The results have revealed that EU structural support has the most significant impact on Lithuanian engineering and technological infrastructure. The impact of the support on country’s macroeconomic, scientific and social environment can also be considered as significant. The EU structural support has medium strong impact on education and business environment conditions in Lithuania. It has been established that, in the field of business advancement, Lithuanian should be rated as medium competitive. Hence, the increase in country’s competitiveness by employing EU structural funds should be treated as one of priority aims. In addition, responsible authorities should perform with higher efficiency seeking for higher competitiveness of the country.

  9. Potential for Introduction of Bat-Borne Zoonotic Viruses into the EU: A Review

    2014-05-01

    Full Text Available Bat-borne viruses can pose a serious threat to human health, with examples including Nipah virus (NiV in Bangladesh and Malaysia, and Marburg virus (MARV in Africa. To date, significant human outbreaks of such viruses have not been reported in the European Union (EU. However, EU countries have strong historical links with many of the countries where NiV and MARV are present and a corresponding high volume of commercial trade and human travel, which poses a potential risk of introduction of these viruses into the EU. In assessing the risks of introduction of these bat-borne zoonotic viruses to the EU, it is important to consider the location and range of bat species known to be susceptible to infection, together with the virus prevalence, seasonality of viral pulses, duration of infection and titre of virus in different bat tissues. In this paper, we review the current scientific knowledge of all these factors, in relation to the introduction of NiV and MARV into the EU.

    2018-04-01

    This paper reports the photoluminescence properties of Eu3+ doped CdF2 single crystals. The pulled crystals were prepared by use of the Bridgman technique from a vacuum furnace in fluoride atmosphere. Absorption, excitation and emission spectra of the crystal doped with three Eu3+ concentrations (0.02%, 0.1% and 0.6% mol.) were recorded at room temperature. The emission spectra exhibit a strong yellow and red emissions in the spectral range 550-720 nm which are assigned to 5D0 → 7FJ (J = 1, 2, 4) transitions and a weak infrared emission around 816 nm corresponding to 5D0 → 7F6 transition. The magnetic dipole emission (5D0 → 7F1) is the most intense for each Eu3+ concentration. The Judd-Ofelt intensity parameters Ω2, Ω4, Ω6 for 4f-4f transitions of Eu3+ ions were computed from the emission spectra using the 5D0 → 7FJ (J = 1, 2, 4, 6) transitions. Via these phenomenological intensity parameters, the spontaneous emission probabilities, branching ratios, radiative lifetimes, quantum efficiencies and emission cross-sections for the main Eu3+ emitting levels are evaluated.

  11. LANGUAGE, POWER AND INTERNATIONAL RELATIONS: THE CASE OF ENGLISH IN THE EU

    Directory of Open Access Journals (Sweden)

    MARÍA LUZ SUÁREZ CASTIÑEIRA

    2013-05-01

    Full Text Available Though generally overlooked, the language question is at the core of International Relations studies: it is associated with power in general and with the concept of “soft power”1 in particular. Indeed, language cannot be considered as just an instrument of communication. In the context of the Nation State as well as in the context of the EU and International Relations in general, it has a strong symbolic value. At the level of the EU and its institutions, the linguistic governance is a very technical and political debate. On the one hand, the European institutions have been promoting multilingualism as crucial for social and political inclusion, but, on the other, English has imposed itself as the main lingua franca. Despite the affirmation of the official character of all national official languages, the EU has never clearly addressed the challenge we are facing. The main focus of this presentation is on whether in the context of regionalization and globalization, English can be stopped from being used as the main lingua franca. First the EU language reality and doctrines will be addressed. Then we shall consider the unbalance of power and the role of English in the EU and worldwide on the basis of several theoretical debates, and finally we shall conclude addressing future challenges.

  12. Support for international trade law: The US and the EU compared.

    Eckhardt, Jappe; Elsig, Manfred

    2015-10-01

    In this article we compare US and EU support for bilateral and multilateral international trade law. We assess the support for international law of both trading blocs by focusing on the following four dimensions: leadership, consent, compliance and internalization. Although we find strong support for international trade law from both the US and the EU in general, we also witness some variation, most notably in relation to the design of preferential trade agreements (PTAs) and compliance with World Trade Organization (WTO) law. Turning to explaining these (moderate) differences, we argue that outcomes in US trade policy can best be explained by a domestic political factor, namely the direct influence of interest groups. Although the involvement of societal interests also goes a long way in explaining EU behavior, it does not tell the entire story. We posit that, in EU trade policy, institutions are a particular conditioning factor that needs to be stressed. Moreover, we suggest that foreign policy considerations in managing trade relations have characterized EU's support for international trade law.

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

    Directory of Open Access Journals (Sweden)

    Nicole de Paula Domingos

    2012-01-01

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

    TiO2(Eu)/CuO nanocomposites were prepared by precipitation method. The anatase nanocrystallites with a size of 26 nm exhibited well crystallized and characteristical dipyramidal morphology and {1 0 1} and {0 0 1} faceting. Transmission electron microscopy photographs with atomic resolution showed that the Eu(III) dopants were bounded on surface of titania. In the composites, the CuO nanocrystals exhibiting a monoclinic tenorite structure with a size in the range from 2 to 5 nm were grafted to the surface of titania. The influence of copper(II) oxide led to distinct selectivity in the photocatalytic and antimicrobial properties of the investigated TiO2(Eu)/CuO nanocomposites. While the presence of CuO nanocrystals strongly increased the photocatalytic production of hydrogen by ethanol reforming, it decreased the activity in photoinduced total mineralization of phenol comparing with non-modified TiO2(Eu). In investigated TiO2(Eu)/CuO powders, the photoinduced antimicrobial activity against membranes of Enterococcus species was influenced by the selective binding of CuO to the surface of the microorganism leading to distinct selectivity in their action. The activity against Enterococcus faecalis was higher than against Enterococcus faecium.

    2013-01-01

    Eu and Rb co-doped LiCaAlF 6 (LiCAF) single crystals with different dopant concentrations were grown by the micro-pulling-down method for neutron detection. Their transmittance spectra showed strong absorption bands at 200–220 and 290–350 nm, and under 241 Am alpha-ray excitation, their radioluminescence spectra exhibited an intense emission peak at 373 nm that was attributed to the Eu 2+ 5d–4f transition. These results were consistent with those for the Rb-free Eu:LiCAF. The highest light yield among the grown crystals was 36,000 ph/n, which was 20% greater than that of the Rb-free crystal. In addition, the neutron-excited scintillation decay times were 650–750 ns slower than that of the Rb-free Eu:LiCAF. -- Highlights: •Eu and Rb co-doped LiCaAlF 6 crystals were grown by the micro-pulling down method. •Transmittance, photoluminescence and radioluminescence spectra were measured. •The light yields and scintillation decays were evaluated under 252 Cf neutron irradiation

    Full Text Available Few months before the Barroso’s mandate completion, the European Commission launched the Communication on an urban dimension of the EU Policies. This one comes to support the achievement of the Europe 2020 Strategy, in the middle of its implementation. The revision of the Strategy is expected in the next spring, and the cities’ fundamental role to reach our common policies objectives is recognized. This is expected to be the key for a more inclusive, sustainable and smarter Europe. The meeting of 28 Mayors of the capital cities of EU on October 1 , 2014 in Rome shows the need to urgently adopt an Urban Agenda of the European Union. The administration of Bucharest strongly supports the initiative and considers as priorities in the coming period: the creation of a data base among the capitals comprising the best practices, making permanent the urban dialogue by creating a platform allowing and encouraging citizens’ involvement in the decision-making actions, the promotion of the success examples and strengthening the experience exchange in the context of the similarity of the problems the current society is confronted with. Meanwhile the subsidiarity is expected to be respect and a large part of European investments available over the next 7 years will be allocated to strategic targets concerning research, innovation and promotion of the small and medium enterprises.

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

    International Nuclear Information System (INIS)

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

    2017-01-01

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

    2016-01-01

    Full Text Available Economic policies and decisions on EU association starting with the begginig of 90’s were pseudo-scientific, contradictory, incoherent because those policies have not based themselves on modern and current economic theories elaborated and promoted by the EU. Actuality. The topic is actual from the perspective of the factors’ analysis which were conducting to delay the association process of Moldova to the EU. At the same time, those were increasing instability, disequilibrium in the national economy and raise of social vulnerability and constraint levels which ultimately increased the gap between the national and EU economic development levels. During the period of 2000-2015, the socio-economic policy of the Republic of Moldova is described more as small and fragmented steps on conceiving economic and financial instruments for the integration into the EU which were reflected in the Neighbourhood Partnership and Association Agreement with the EU.

The scope of the present article is to propose a real change of the development and social-economic association policies for achieving final objective on integration to EU. The proposals would consist in emphasizing and implementation of the EU economic principles reflected in the neoclassic synthesis and neo-conservative theories; the elaboration and implementation of a new Strategy on economic supervision, coordination and anticipation of the economic disequilibrium; achieve economic stability for diminishing the negative effects of the global and regional crisis on national economy and adaptation of the development policies to the national socio-economic conditions.

    Full Text Available The united general growth strategy for all EU Member States, a common economic and political vision as well as location in the same geographic region provides a necessary basis for the benchmarking modelling of economies. The main objective of this study is determination of the functional regularities and drivers of the growth of EU economies and the context of the Baltic States in line with the general trend of the EU, as well as development of the growth model, which can be used for sustainable planning and prediction. Analysis of several regularly published analytical indexes suggests a thesis on innovation as the real basic driving force for EU economies and outlines Innovation Performance Index, which have a very strong compliance with the economic growth of particular country. At the same time study of the data set and methodology of the Index indicates space for further optimization. By use of several linear regression tools the growth model was created. It is based on three hard independent statistical indicators (predictors only; of course, these indicators is a peak of a complex pyramid. Despite of the simplicity of the model, the long-term correlation of fitted values with the real GDP per capita is extremely strong 0.961 – 0.987.

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

    Energy Technology Data Exchange (ETDEWEB)

    2009-07-06

    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{sub 3}O{sub 4}, Eu{sub 2}O{sub 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

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.

    2009-07-01

    Since the 1990s, railway services in new EU member states have been undergoing a major transformation. This is connected on the one hand with the transition from a central planning to a market-based economy, and on the other hand with the application of the so-called ''railway packages'' of the European Union. Further changes are related to the evolution of the transport infrastructure and the extension of the Schengen Agreement to these countries. Thanks to the reforms undertaken and the application of the railway packages, the principal prerequisites for the stability of rail freight transport in central and eastern European countries have been fulfilled, although various issues still remain to be addressed in some countries. Fair competition between all modes of transport is developing in the new EU member states as in the old. In the area of infrastructure, strong support from the European Commission will continue to be required, namely through the structural and cohesion funds. (orig.)

    Highlights: • PLD production of high quality europium sesquioxide (Eu{sub 2}O{sub 3}) films. • The deposition of Al{sub 2}O{sub 3} capping and/or buffer layers modifies the crystallization for Eu{sub 2}O{sub 3} films upon annealing. • The formation of cubic or monoclinic phases can be favored. • Eu{sup 3+} emission tuning is achieved as a consequence of crystal field effects. - Abstract: We report the growth of europium sesquioxide (Eu{sub 2}O{sub 3}) thin films by pulsed laser deposition (PLD) in vacuum at room temperature from a pure Eu{sub 2}O{sub 3} ceramic bulk target. The films were deposited in different configurations formed by adding capping and/or buffer layers of amorphous aluminum oxide (a-Al{sub 2}O{sub 3}). The optical properties, refractive index and extinction coefficient of the as deposited Eu{sub 2}O{sub 3} layers were obtained. X-ray photoelectron spectroscopy (XPS) measurements were done to assess its chemical composition. Post-deposition annealing was performed at 500 °C and 850 °C in air in order to achieve the formation of crystalline films and to accomplish photoluminescence emission. According to the analysis of X-ray diffraction (XRD) spectra, cubic and monoclinic phases were formed. It is found that the relative amount of the phases is related to the different film configurations, showing that the control over the crystallization phase can be realized by adequately designing the structures. All the films showed photoluminescence emission peaks (under excitation at 355 nm) that are attributed to the intra 4f-transitions of Eu{sup 3+} ions. The emission spectral shape depends on the crystalline phase of the Eu{sub 2}O{sub 3} layer. Specifically, changes in the hypersensitive {sup 5}D{sub 0} → {sup 7}F{sub 2} emission confirm the strong influence of the crystal field effect on the Eu{sup 3+} energy levels.

    Full Text Available The participation of countries in GVCs can be measured in different ways; most commonly by using the GVC participation index and the GVC position index. The research is focused on the analysis of GVC participation of EU member states applying different indicators and comparing the characteristics of three groups of EU member states (EU core members, EU Southern members and EU new member states. We have applied statistical analysis on the TiVA database. The results indicate a high level of participation of EU member states in GVCs with a predominance of backward linkages. Luxembourg, Slovakia and Hungary have the highest levels of participation while Croatia has the lowest participation. EU member states are very integrated and intra-regional, so about 80% of value added in their gross export or final demand originates from the EU (domestic value added or value added from other member states.

    This paper describes the legal and system framework of energy policy in EU. It also summarizes the previous progress for the establishment of a single energy market. Organization, which deals with energy policy within EU, consists of Commission, Council of Ministers and European Parliament. The policy decision method in EU is classified into six ways due to the proposal and decision of the Commission and Council of Ministers. The establishment of a single market for energy products and services is included in a concept of so-called common market. Coal, oil, natural gas and nuclear energy are included in the energy market. The purpose of establishment of a single energy market is to promote a free and fair competition. The target of Competition Policy Commission in the energy division is to establish the enhanced competition, stable supply and maintenance of public services, compatibly. Furthermore, the current status of private management and reconstruction in EU is described.

    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)

    2014-12-01

    We introduce the European Rapid Raw Strong-Motion database (RRSM), a Europe-wide system that provides parameterised strong motion information, as well as access to waveform data, within minutes of the occurrence of strong earthquakes. The RRSM significantly differs from traditional earthquake strong motion dissemination in Europe, which has focused on providing reviewed, processed strong motion parameters, typically with significant delays. As the RRSM provides rapid open access to raw waveform data and metadata and does not rely on external manual waveform processing, RRSM information is tailored to seismologists and strong-motion data analysts, earthquake and geotechnical engineers, international earthquake response agencies and the educated general public. Access to the RRSM database is via a portal at http://www.orfeus-eu.org/rrsm/ that allows users to query earthquake information, peak ground motion parameters and amplitudes of spectral response; and to select and download earthquake waveforms. All information is available within minutes of any earthquake with magnitude ≥ 3.5 occurring in the Euro-Mediterranean region. Waveform processing and database population are performed using the waveform processing module scwfparam, which is integrated in SeisComP3 (SC3; http://www.seiscomp3.org/). Earthquake information is provided by the EMSC (http://www.emsc-csem.org/) and all the seismic waveform data is accessed at the European Integrated waveform Data Archive (EIDA) at ORFEUS (http://www.orfeus-eu.org/index.html), where all on-scale data is used in the fully automated processing. As the EIDA community is continually growing, the already significant number of strong motion stations is also increasing and the importance of this product is expected to also increase. Real-time RRSM processing started in June 2014, while past events have been processed in order to provide a complete database back to 2005.

    Full Text Available This paper analyzes the quality of governance and financial assistance as key determinants for successful functioning of the process of integration within the European Union (EU. Moreover, the paper develops a comparison of the Western Balkans with current EU members and the forthcoming, on the basis of the selected indicators of governance (rule of law, democracy, corruption, political stability, and effectiveness of state with the experience of the implementation of the reforms of public administration. Various surveys show that the Western Balkans, by all quality of governance indicators, especially in the rule of law, lags behind 28 (twenty eight of the current EU countries (without taking in account the Great Britain. The low level of the functioning of rule of law, combined with inadequate and unreformed public administration is potentially the biggest obstacle in the association agreement of the Western Balkans with EU, but also as challenge in achieving sustainable social and economic development. Whereas in the case of the Western Balkan countries, there is an obvious difference between proclaiming and internal reality, which is further compounded by a difficult political and economic transition, as well as in social domain - where poverty and corruption are the most worrying. The research data obtained from independent bodies - academic and research institutions, civil society and international organizations - confirm this controversial picture of the Western Balkans. Negative attitudes still prevail in Western Balkans political elites and if given the chance to political manipulation, may behave unpredictably. All this makes it obligatory to make a comparative overview, for depicting in particular the quality of governance as sine qua non for the Western Balkans countries‘ integration in EU.

Display Omitted - Highlights: • Eu 2+ and Mn 2+ codoped SrSi 2 O 2 N 2 phosphors were first synthesized by sol–gel method. • The green emission of Eu 2+ was greatly enhanced by codoping Mn 2+ ions. • The reason is attributed to the coexcitation and energy transfer from Mn 2+ to Eu 2+ . • SrSi 2 O 2 N 2 : Eu 2+ , Mn 2+ also exhibits a higher quantum yield and better thermal stability. • SrSi 2 O 2 N 2 :Eu 2+ , Mn 2+ is a promising green-emitting phosphor for WLEDs. - Abstract: Eu 2+ and Mn 2+ co-doped SrSi 2 O 2 N 2 phosphors were firstly synthesized via a simple sol–gel method using low-cost SrCO 3 , Eu 2 O 3 , Mn(CH 3 COO) 2 ⋅ 4H 2 O, α-Si 3 N 4 and C 8 H 20 O 4 Si (TEOS) as the starting materials. Their luminescence properties, quantum yield, and thermal stability were investigated in comparison with the single Eu 2+ doped samples. The green emission intensity of Eu 2+ ions is greatly enhanced by introducing Mn 2+ ions into SrSi 2 O 2 N 2 :Eu 2+ due to the coexcitation and energy transfer between Mn 2+ and Eu 2+ . The energy transfer probability from Mn 2+ to Eu 2+ depends strongly on the Mn 2+ concentration, which is maximized at 2.0 mol%. Mn 2+ . Simultaneously, quantum efficiency and thermal stability in SrSi 2 O 2 N 2 :0.03Eu 2+ , 0.02Mn 2+ is dramatically improved. All these excellent optical properties indicate that SrSi 2 O 2 N 2 :Eu 2+ , Mn 2+ synthesized in the present work is a promising green-emitting phosphor for white-light emitting diodes with near-UV LED chips

  7. EU Climate Policy Tracker 2011. Main report

    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

    Highlights: • Nanocomposites composed of Eu-doped anatase grafted with CuO. • Increase in photocatalytic hydrogen production due to CuO acting as electrons sink. • CuO in composites decreasing the photoinduced total mineralization of phenol. • Selective photoinduced antimicrobial activity against Enterococcus species. - Abstract: TiO 2 (Eu)/CuO nanocomposites were prepared by precipitation method. The anatase nanocrystallites with a size of 26 nm exhibited well crystallized and characteristical dipyramidal morphology and {1 0 1} and {0 0 1} faceting. Transmission electron microscopy photographs with atomic resolution showed that the Eu(III) dopants were bounded on surface of titania. In the composites, the CuO nanocrystals exhibiting a monoclinic tenorite structure with a size in the range from 2 to 5 nm were grafted to the surface of titania. The influence of copper(II) oxide led to distinct selectivity in the photocatalytic and antimicrobial properties of the investigated TiO 2 (Eu)/CuO nanocomposites. While the presence of CuO nanocrystals strongly increased the photocatalytic production of hydrogen by ethanol reforming, it decreased the activity in photoinduced total mineralization of phenol comparing with non-modified TiO 2 (Eu). In investigated TiO 2 (Eu)/CuO powders, the photoinduced antimicrobial activity against membranes of Enterococcus species was influenced by the selective binding of CuO to the surface of the microorganism leading to distinct selectivity in their action. The activity against Enterococcus faecalis was higher than against Enterococcus faecium.

    Red-emitting Eu3+-doped (Y,Gd)BO3 phosphors have been synthesized by a sol-gel process using metal oxides and boric acid as starting materials and citric acid as chelating agent. The main factors affecting the structure and luminescence properties of the product, such as sintering temperature, chemical composition, and Eu3+ doping concentration, were investigated. X-ray diffraction (XRD) analysis indicated that the phosphors begin to crystallize at sintering temperature of 700°C and become phase pure at 900°C. The average size of the phosphor particles after sintering at 1000°C was determined to be about 30 nm to 50 nm. The (Y,Gd)BO3:Eu3+ phosphors were found to exhibit strong red emission at 611 nm and 625 nm corresponding to the 5D0-7F2 transitions of Eu3+ in the host lattice. The photoluminescence intensity was enhanced by posttreatment at 900°C and remained unchanged at 1000°C. It was also found that the optimal concentration of Gd3+ ions for Eu3+ emission was 35%, and no concentration quenching of the photoluminescence was observed even at Eu3+ doping concentration up to 30%.

  11. The initial impact of EU ETS verification events on stock prices

    2016-01-01

    This paper studies the impact of verified emissions publications in the European Emissions Trading Scheme (EU ETS) on the market value of participating companies. Using event study methodology on a unique sample of 368 listed companies, we show that verified emissions only resulted in statistically significant market responses when the carbon price was high and allowance scarcity was anticipated. The cross-section analysis of abnormal returns surrounding the publication of verified emissions shows that share prices decrease when actual emissions relative to allocated emissions increase. This negative relationship between allocation shortfalls and firm value is only significant for firms that are either carbon-intensive, compared to sector peers, or are less likely to pass through carbon-related costs in their product prices. The results suggest that although the EU ETS has been deemed unsuccessful so far due to over-allocation and low carbon price, shareholders initially perceived allowance holdings as value relevant. Our results highlight that a significant carbon market price and addressing pass-through costing are essential for successful future reforms of the EU ETS and other analogous carbon cap-and-trade systems implemented or planned worldwide. - Highlights: •We study the impact of EU ETS verified emissions disclosure on firms' market value. •Disclosure is relevant if carbon price is high and permits scarcity is anticipated. •We find a negative relationship between allocation shortfalls and firm value. •Stronger relationship for carbon – intensive and no cost pass-through firms. •High carbon price and addressing cost pass-through are crucial for EU ETS reforms.

  12. Manipulating light with strongly modulated photonic crystals

    2010-01-01

    Recently, strongly modulated photonic crystals, fabricated by the state-of-the-art semiconductor nanofabrication process, have realized various novel optical properties. This paper describes the way in which they differ from other optical media, and clarifies what they can do. In particular, three important issues are considered: light confinement, frequency dispersion and spatial dispersion. First, I describe the latest status and impact of ultra-strong light confinement in a wavelength-cubic volume achieved in photonic crystals. Second, the extreme reduction in the speed of light is reported, which was achieved as a result of frequency dispersion management. Third, strange negative refraction in photonic crystals is introduced, which results from their unique spatial dispersion, and it is clarified how this leads to perfect imaging. The last two sections are devoted to applications of these novel properties. First, I report the fact that strong light confinement and huge light-matter interaction enhancement make strongly modulated photonic crystals promising for on-chip all-optical processing, and present several examples including all-optical switches/memories and optical logics. As a second application, it is shown that the strong light confinement and slow light in strongly modulated photonic crystals enable the adiabatic tuning of light, which leads to various novel ways of controlling light, such as adiabatic frequency conversion, efficient optomechanics systems, photon memories and photons pinning.

    The mixed solvent-thermal method has been developed for the synthesis of YVO 4 :Eu 3+ luminescent materials in the N, N-dimethylformamide (DMF)/ de-ionized water (DIW) solution. The samples have been characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electronic microscope (TEM), UV/vis absorption and photoluminescence spectroscopies. The results demonstrate that we have obtained the uniform YVO 4 :Eu 3+ cobblestone - like microcrystalline phosphors in the mixed solution of DMF and DIW, which are different to the as-obtained YVO 4 :Eu 3+ nanoparticles in pure DIW. And the as - prepared YVO 4 :Eu 3+ microcrystalline particles are composed of numerous nanoparticles. The assembling phenomenon of the nanoparticles is strongly affected by the pH value of the solution and the volume ratio of DMF/DIW. Under UV excitation, the samples can emit the bright red light. While, the photoluminescence (PL) intensities of YVO 4 :Eu 3+ show some difference for samples obtained under the different reaction conditions. This is because that different microstructures of samples result in different combinative abilities between the surface and the adsorbed species so as to produce the different quenching abilities to the emission from Eu 3+ ions.

    Full Text Available This article analyses the issues of EU energy policy in the 1990s-the beginning of the 2000s in order to identify the features of energy supply and energy safety of the Baltic region countries. The research and practical significance of the work lies in the stepwise description of actions taken by EU leaders and EU member states in order to formulate a common European energy policy. The 2004 EU enlargement posed the problem of taking into account the features of energy supply of Eastern European countries and, especially, the Baltic States. The energy industries of Lithuania, Latvia, and Estonia, as well as other Eastern European and CIS countries, are closely related to the energy industry of the Russian Federation. Trying to allow for this circumstance, EU leaders and energy structures took a number of organizational measures aimed, on the one hand, at an increase in energy independence of new members of the EU and, on the other hand, at taking into account the recent trends in the energy market development. The research shows that most of the initiatives do not take into account the perspective and interests of Russia, which has a strong presence in the energy market. The analysis conducted will help the assessment of prospects of further development of the Baltic States' energy industry and its interaction with that of the Russian Federation.

    We report on a comprehensive spectroscopic study of monoclinic Eu:KLu(WO 4 ) 2 crystal concerning its potential applications in red lasers. Optical absorption and stimulated-emission cross-section spectra are determined for this crystal for the principal light polarizations, E || N p , N m and N g . The maximum σ SE corresponding to the 5 D 0 → 7 F 4 transition is 1.78×10 −20 cm 2 at 703.5 nm (for E || N m ). Spectroscopic properties of Eu:KLu(WO 4 ) 2 are modeled within the conventional Judd–Ofelt theory, as well as its modification for systems with an anomalously strong configuration interaction (ASCI), yielding absorption oscillator strengths, luminescence branching ratios for 5 D J → 7 F J' transitions and radiative lifetimes of the 5 D J states. Photoluminescent properties of Eu:KLu(WO 4 ) 2 are studied under UV/visible excitation. Polarized Raman spectra are measured for Eu:KLu(WO 4 ) 2 . - Highlights: • Top-seeded solution growth of Eu:KLu(WO 4 ) 2 monoclinic crystal. • Modeling of spectroscopic parameters with modified Judd–Ofelt theory. • Polarization-resolved absorption and stimulated-emission cross-section spectra. • Maximum stimulated-emission cross-section is 1.78×10 −20 cm 2 at 703.5 nm. • Polarized Raman spectroscopy of Eu:KLu(WO 4 ) 2 crystal.

    Hollow europium-doped yttrium orthovanadate (YVO4:Eu3+) microspheres were fabricated via a sodium dodecyl sulfate (SDS)-polyethylene glycol (PEG)-assisted hydrothermal technique. The as-synthesized hollow YVO4:Eu3+ microspheres were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and photoluminescence spectroscopy (PL). The obtained results showed that the morphology and size of the hollow microspheres have a strong dependence on the hydrothermal reaction time of the YVO4:Eu3+ powders. It is believed that the SDS-PEG clusters perform a function of dual soft-template that results in a unique template-induced secondary assembly in the one-pot synthesis of hollow YVO4:Eu3+ microspheres. The photoluminescence measurement revealed that the YVO4:Eu3+ powders with a spherical hollow shape have better red luminescence compared to the YVO4:Eu3+ solid microspheres. As a result, the controlled synthesis of hollow YVO4:Eu3+ microspheres not only has a great theoretical significance in studying the three-dimensional control and selective synthesis of inorganic materials but also benefits the potential applications based on hollow YVO4:Eu3+ microspheres owing to reducing the usage of expensive rare-earth elements.

    EuFe 2 As 2 -based iron pnictides are quite interesting compounds, due to the two magnetic sublattices in them and the tunability to superconductors by chemical doping or application of external pressure. The effects of hydrostatic pressure on the static magnetism in Eu(Fe 0.925 Co 0.075 ) 2 As 2 are investigated by complementary electrical resistivity, ac magnetic susceptibility and single-crystal neutron diffraction measurements. A specific pressure-temperature (P-T) phase diagram of Eu(Fe 0.925 Co 0.075 ) 2 As 2 is established. The structural phase transition, as well as the spin-density-wave order of Fe sublattice, is suppressed gradually with increasing pressure and disappears completely above 2.0 GPa. In contrast, the magnetic order of Eu sublattice persists over the whole investigated pressure range up to 14 GPa, yet displaying a non-monotonic variation with pressure. With the increase of the hydrostatic pressure, the magnetic state of Eu evolves from the canted antiferromagnetic structure in the ground state, via a pure ferromagnetic structure under the intermediate pressure, finally to an "unconfirmed" antiferromagnetic structure under the high pressure. The strong ferromagnetism of Eu coexists with the pressure-induced superconductivity around 2 GPa. Comparisons between the P-T phase diagrams of Eu(Fe 0.925 Co 0.075 ) 2 As 2 and the parent compound EuFe 2 As 2 were also made.

    A blue-emitting phosphor Ca 12 Al 14 O 32 F 2 :Eu 2+ was synthesized using a high-temperature solid-state reaction under a reductive atmosphere. The X-ray diffraction measurements indicate that a pure phase Ca 12 Al 14 O 32 F 2 :Eu 2+ can be obtained for low doping concentration of Eu 2+ . The phosphor has a strong absorption in the range 270-420 nm with a maximum at ~340 nm and blue emission in the range 400-500 nm with chromatic coordination of (0.152, 0.045). The optimal doping concentration is ~0.24. In addition, the luminescence properties of the as-synthesized phosphor were evaluated by comparison with those of Ca 12 Al 14 O 32 Cl 2 :Eu 2+ and the commercially available phosphor BaMgAl 10 O 17 :Eu 2+ . The emission intensity of Ca 12 Al 14 O 32 F 2 :Eu 2+ was ~72% that of BaMgAl 10 O 17 :Eu 2+ under excitation at λ = 375 nm. The results indicate that Ca 12 Al 14 O 32 F 2 :Eu 2+ has potential application as a near-UV-convertible blue phosphor for white light-emitting diodes. Copyright © 2017 John Wiley & Sons, Ltd.

  6. 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.

    1998-01-01

    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)

    Full Text Available Persistent luminescent materials are able to emit light for hours after being excited. The majority of persistent phosphors emit in the blue or green region of the visible spectrum. Orange- or red-emitting phosphors, strongly desired for emergency signage and medical imaging, are scarce. We prepared the nitrido-silicates Ca2Si5N8:Eu (orange, Sr2Si5N8:Eu (reddish, Ba2Si5N8:Eu (yellowish orange, and their rare-earth codoped variants (R = Nd, Dy, Sm, Tm through a solid state reaction, and investigated their luminescence and afterglow properties. In this paper, we describe how the persistent luminescence is affected by the type of codopant and the choice and ratio of the starting products. All the materials exhibit some form of persistent luminescence, but for Sr2Si5N8:Eu,R this is very weak. In Ba2Si5N8:Eu the afterglow remains visible for about 400 s, and Ca2Si5N8:Eu,Tm shows the brightest and longest afterglow, lasting about 2,500 s. For optimal persistent luminescence, the dopant and codopant should be added in their fluoride form, in concentrations below 1 mol%. A Ca3N2 deficiency of about 5% triples the afterglow intensity.

    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.

Results show that the nanocomposites are spherical with a mean diameter of 700 nm and there are high special saturation magnetization (47.4 emu/g) and strong red emission under UV-light. Even dispersed in water solution, the nanocomposites also exhibit a strong red emission under ultraviolet light radiation, and it could be manipulated using an external magnet. Thus it looks promising for application in biomedicine field, especially in drug targeting and fluorescence label. And we also discussed the effect of the electron transfer process between the Fe magnetic core and Y 2 O 3 :Eu 3+ shell.

    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

  17. DEINDUSTRIALIZATION AS A PROCESS IN THE EU

    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.

    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.

    2014-01-01

    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.

    Full Text Available This paper examines the dynamic effect of the economic determinants on bilateral trade intensity of the European Union (EU region’s bioenergy industry outputs. The authors adopt the panel co-integration model approach to estimate annual trade intensity data of the EU-28 countries’ bioenergy industry outputs from 1990 to 2013. This study investigated the long-term influence of the rate of real exchange, gross domestic product (GDP, and export price on the trade intensity of bioenergy industry applying fully modified oriented least square (FMOLS, dummy oriented least square (DOLS, and pooled mean group (PMG models. In the current study, the findings boost the empirical validity of the panel co-integration model through FMOLS, indicating that depreciation has improved the trade intensity. This study has further investigated, through the causality test, a distinct set of countries. FMOLS estimation does find proof of the long run improvement of trade intensity. Thus, the result shows that the gross domestic product (GDP and the real exchange rate have a positive and noteworthy influence on the EU-28 region trade intensity of the bioenergy industry. Moreover, the export price affects negatively and significantly the trade intensity of the bioenergy industry in the EU-28 countries.

    A secure supply of raw materials is a European priority that extends beyond country borders and national policies. Recent European initiatives have pioneered the development of an EU strategy on raw materials emphasizing the concept of the "added value chain", which continues to pursue the three pillar strategy to: (1) ensure the fair and sustainable supply of raw materials from international markets, promoting international cooperation with developed and developing countries; (2) foster sustainable supply of raw materials from European sources, and (3) reduce consumption of primary raw materials by increasing resource efficiency and promoting recycling. This contribution presents the Horizon 2020 funded project INTRAW, the objective of which is to establish the European Union's International Observatory for Raw Materials. The creation and maintenance of the European Union's International Observatory for Raw Materials is designed to have a strong impact in two dimensions: 1. To narrow the existing gap in aspects of the raw materials knowledge infrastructure in the EU by providing a link with the same knowledge infrastructure in technologically advanced reference countries. This should contribute to the harmonization of mineral policies all over the EU, by providing data that enables evidence-based policies and appropriate, cost-effective management, planning and adaptation decisions by the public sector. This will benefit businesses, industry and society. The Observatory will also provide to policy makers in the EU and its Member States the data they need to facilitate discussion in multilateral forums. 2. To enable a better alignment of the R&I activities among the individual EU members and international cooperation countries AND between the European Union and international cooperation countries by boosting synergies with international research and innovation programmes. This way the EU's role and scientific capabilities in the raw materials area will be

    Calcite is an important component of Valanginian marl, a potential host rock for a low and intermediate level radioactive waste (L/ILW) repository in Switzerland. This mineral also forms an important component of the disturbed zone around a repository, as it remains largely unaffected by the hyperalkaline waters migrating out of the cementitious repository . The sorption behaviour of Eu(III) and Th(IV) on Merck calcite in an artificial cement pore water (ACW) at pH 13.3 has been studied in batch-type sorption experiments. In addition, the effect of α-isosaccharinic acid (ISA) and gluconic acid (GLU) on the sorption of these two cations has been investigated. In the absence of ISA and GLU, a strong interaction of Eu(III) and Th(IV) with Merck calcite was observed. Eu(III) and Th(IV) sorption kinetics were fast and the isotherms indicated a linear adsorption behaviour over the experimentally accessible concentration range. In the case of Eu(III), a decrease of the R d value with increasing solid to liquid (S:L) ratio was observed indicating that, along with adsorption, other processes might influence the immobilisation of this cation by Merck calcite under ACW conditions. In the case of Th(IV), however, changes in the S:L ratio had no effect on the sorption behaviour . High ISA and GLU concentrations in solution significantly affected the sorption of both Eu(III) and Th(IV): R d values for Eu(III) decreased significantly at ISA concentrations higher than 10 -5 M and at GLU concentrations higher than 10 -7 M. The sorption of Th(IV) was reduced at ISA concentrations above 2.10 -5 M and at GLU concentrations above 10 -6 M. The effects of ISA and GLU on the immobilisation of Eu(III) and Th(IV) were interpreted in terms of complex formation in solution. In the case of Eu(III) the metal ligand complexes were found to have a 1 : 1 stoichiometry. Complexation constants derived for the aqueous Eu(III)-ISA. and Eu(III)GLU complexes were determined to be logβ 0 EulSA = -31.1

    The indirect bandgap of single-crystalline silicon has so far precluded the full integration of silicon microelectronics with photonics—which is expected to allow the realization of low-cost, high-speed optical information processing and communication in the future. Here we report the growth of europium (Eu)-doped Si-SiO2 core-shell nanowires by an oxide-assisted chemical vapor deposition method. The Eu concentration in these nanowires is effectively improved by intentionally increasing the thickness of SiO2 shells. As a result, a strong Si-compatible red emission from Eu3+ ions was observed under laser illumination. The effect of Eu3+ concentration on the emission efficiency was comprehensively studied, with the highest efficiency at Eu content about 0.8 at%. The relaxation mechanism of this concentration dependent luminescence was further explored through lifetime measurements. In light of the strong characteristic red emission and nanoscale footprint, these nanowires are promising Si-compatible light emission materials for future integrated nanophotonics.

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

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

    The Natura 2000 network is regarded as one of the conservation success stories in the global effort to protect biodiversity. However, significant challenges remain in Natura 2000 implementation, owing to its rapid expansion, and lack of a coherent vision for its future. Scientific research is critical for identifying conservation priorities, setting management goals, and reconciling biodiversity protection and society in the complex political European landscape. Thus, there is an urgent need for a comprehensive evaluation of published Natura 2000 research to highlight prevalent research themes, disciplinary approaches, and spatial entities. We conducted a systematic review of 572 scientific articles and conference proceedings focused on Natura 2000 research, published between 1996 and 2014. We grouped these articles into 'ecological' and 'social and policy' categories. Using a novel application of network analysis of article keywords, we found that Natura 2000 research forms a cohesive small-world network, owing to the emphasis on ecological research (79% of studies, with a strong focus on spatial conservation planning), and the underrepresentation of studies addressing 'social and policy' issues (typically focused on environmental impact assessment, multi-level governance, agri-environment policy, and ecosystem services valuation). 'Ecological' and 'social and policy' research shared only general concepts (e.g., Natura 2000, Habitats Directive) suggesting a disconnection between these disciplines. The UK and the Mediterranean basin countries dominated Natura 2000 research, and there was a weak correlation between number of studies and proportion of national territory protected. Approximately 40% of 'social and policy' research and 26% of 'ecological' studies highlighted negative implications of Natura 2000, while 21% of studies found positive social and biodiversity effects. We emphasize the need for designing inter- and transdisciplinary research in order to

    2009-01-01

    During the 1990s, limited investment opportunities in Western Europe, the opening of the energy markets in Eastern Europe, and the future expansion of the European Union (EU) prompted an expansionist strategy by energy companies from the original EU member states. In this paper, the acquisition and divestiture activities and strategies of utilities from France and Germany are analyzed in the context of the 2004 and 2007 EU enlargements. Through quantitative and qualitative data analysis, including the development of two case studies, the strategy for expansion and evolution in new member states is examined. The results demonstrate a concerted effort to establish economies of scale through ownership of distribution companies. A change in strategy occurs as these privatization opportunities disappear. Generation and trading activity become the growth area for these companies as electricity supply becomes another factor that can contribute to the economies of scale. Recent EU-supported efforts towards regionalization of electricity markets, positions these companies well due to their strong regional presence. This paper will explore these issues in the context of ownership and geographic distribution. (author)

    A blue CaMgSi2O6:Eu(2+) phosphor was prepared by the solid-state reaction method and the phosphor characterized in terms of crystal structure, particle size, photoluminescence (PL), thermoluminescence (TL) and mechanoluminescence (ML) properties using X-ray diffraction (XRD), transmission electron microscopy (TEM), PL spectroscopy, TLD reader and ML impact technique. The XRD result shows that phosphor is formed in a single phase and has a monoclinic structure with the space group C2/c. Furthermore, the PL excitation spectra of Eu(2+) -doped CaMgSi2 O6 phosphor showed a strong band peak at 356 nm and the PL emission spectrum has a peak at 450 nm. The depths and frequency factors of trap centers were calculated using the TL glow curve by deconvolution method in which the trap depths were found to be 0.48 and 0.61 eV. The formation of CaMgSi2O6:Eu(2+) phosphor was confirmed by Fourier transform infrared spectroscopy. The ML intensity increased linearly with the impact velocity of the piston used to deform the phosphor. It was shown that the local piezoelectricity-induced electron bombardment model is responsible for the ML emission. Finally, the optical properties of CaMgSi2O6:Eu(2+) phosphors are discussed.

  13. 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

    Eu{sup 3+}/Gd{sup 3+} co-doped silicate sol–gel powders have been successfully obtained. The effect of high concentration of gadolinium ions on visible emission of europium ions in prepared materials has been studied under different excitation wavelengths. Spectroscopic properties of Eu{sup 3+} and Gd{sup 3+} ions in prepared powders were determined based on excitation and emission measurements as well as luminescence decay analysis. In the visible spectral range the observed emission bands correspond to transitions of trivalent Eu{sup 3+} and Gd{sup 3+} ions. The changes of excitation mechanism of optically active dopants significantly affect the increase of luminescence intensities. The luminescence lifetime for the {sup 5}D{sub 0} level of Eu{sup 3+} ions in examined samples upon excitation at λ{sub exc}=273 nm ({sup 8}S{sub 7/2}→{sup 6}I{sub J} transition of Gd{sup 3+}) is about 12 times longer in comparison to excitation at λ{sub exc}=393 nm ({sup 7}F{sub 0}→{sup 5}L{sub 6} transition of Eu{sup 3+}). The luminescence intensity coefficient R (Eu{sup 3+}) was also calculated, and it was found that ratio of the intensity of red to orange emission depends on the excitation wavelength. Based on determined spectroscopic parameters the energy transfer process from Gd{sup 3+} to Eu{sup 3+} ions was confirmed. - Highlights: • Eu{sup 3+}/Gd{sup 3+} co-doped silicate powders have been fabricated. • The emission bands in the visible range correspond to transitions of Eu{sup 3+} and Gd{sup 3+}. • The lifetime for the {sup 5}D{sub 0} state of Eu{sup 3+} upon excitation at 273 nm is strongly prolonged. • Efficient energy transfer from Gd{sup 3+} to Eu{sup 3+} ions was confirmed.

  15. 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.

Stoichiometric compounds such as cubic Eu3Ga5O12 (EGG) and orthorhombic Eu3GaO6 were synthesized using molar ratios of x = 0.375 and 0.75 [x≡Eu2O3/(Eu2O3 + Ga2O3)], respectively, together with the end-point binary compounds β-Ga2O3 (x = 0) and monoclinic (m-) Eu2O3 (x = 1.0). The structural change from "cubic" to "monoclinic" in Eu2O3 is due to the structural phase transition occurring at Tc ≥ 1050 °C. In principle, the perovskite-type EuGaO3 and monoclinic Eu4Ga2O9 can also be synthesized at x = 0.5 and 0.667, respectively; however, such stoichiometric compounds could not be synthesized in this study. The PL and PLE properties of EGG and Eu3GaO6 were studied in detail. The temperature dependence of the PL spectra was observed through measurements carried out between T = 20 and 300 K and explained using a newly developed model. Raman scattering measurements were also performed on the Eu-Ga-O ternary systems over the entire composition range from x = 0 (β-Ga2O3) to 1.0 (m-Eu2O3).

    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

  18. EU BUDGET – THE POLICY OF SHARING THE CAKE

    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.

    Many countries in the European Union (EU) have very developed waste management systems. Some of its members have managed to reduce their landfilled waste to values close to zero during the last decade. Thus, European Union legislation is very stringent regarding waste management for their members and candidate countries, too. This raises the following questions: Is it possible for developing and developed countries to comply with the European Union waste legislation, and under what conditions? How did waste management develop in relation to the economic development in the countries of the European Union? The correlation between waste management practices and economic development was analysed for 27 of the European Union Member States for the time period between 1995 and 2007. In addition, a regression analysis was performed to estimate landfilling of waste in relation to gross domestic product for every country. The results showed a strong correlation between the waste management variables and the gross domestic product of the EU27 members. The definition of the municipal solid waste management development phases followed a closer analysis of the relation between gross domestic product and landfilled waste. The municipal solid waste management phases are characterised by high landfilling rates at low gross domestic product levels, and landfilling rates near zero at high gross domestic product levels. Hence the results emphasize the importance of wider understanding of what is required for developing countries to comply with the European Union initiatives, and highlight the importance of allowing developing countries to make their own paths of waste management development. © The Author(s) 2015.

    The treatment and disposal of tyres from vehicles has long been of considerable environmental importance. The main problem lies in the mixed composition of the tyres. Studies have been undertaken to modify the structure of the tyres, especially with reference to the percentage of granulated rubber incorporated, in order to improve their performance, and also to reduce their environmental impact during normal functioning (noise, particulates, etc.) and facilitate recycling and final disposal. The aim of the present study is to review and compare how used tyres are treated and disposed of in two different EU countries. The first is Italy, which has been part of the European Union since its inception, and has important industrial traditions. The second is Romania, an emerging country which recently became part of the EU, and whose economic and industrial development has had a major boost in recent years, with a strong growth in waste production, together with consumption in urban areas. The occasion was useful to consider the situation concerning the evolution of the different aspects related to the management of the end-of-life tyres. In particular, the paper considers the properties of tyre waste and their potential reuse, the enhancement of end-of-life tires and the various types of recovery, such as the reconstruction of tyres and the material recovery. The aspects related to the energy recovery and the use of the life cycle analysis, as a tool to support the choices of the best management system, were also taken into consideration, not forgetting that an adequate end-of-life planning is important when developing a sustainable product, since it can affect considerably its overall life cycle.

  1. A comprehensive analysis of the current and future role of biofuels for transport in the European Union (EU

    Directory of Open Access Journals (Sweden)

    Massimo Raboni1

    2015-01-01

    Full Text Available The production of biofuels is strongly supported all over the world as a renewable energy source for reducing dependence on the unstable oil market. Bioethanol, the main biofuel produced in the world, is widely used to power vehicles in both the USA and Brazil, but concerns exist in both places regarding its sustainability. In Brazil, it is produced from a by-product of the sugar cane industry, while in the USA it is manufactured from food crops. The production of biogas and biodiesel is growing rapidly, but neither has outpaced the production of bioethanol. The European Union (EU is greatly interested in this issue, and in 2011 adopted an extensive strategy to reduce carbon dioxide emissions related to transport by 60% by the year 2050. In order to achieve this result, the current European transportation system must be transformed. This ambitious goal will require the implementation of complex measures including the reduction of fossil fuels in favor of renewable fuels. This program has various options regarding the development of biofuels (e. g., biogas, bioethanol and biodiesel and their related technologies, which are still on trial (mainly regarding the bioethanol production, and must also analyze their sustainability from a social and economic standpoint. The paper discusses the use of biofuels for transport in the European setting, and shows that their sustainability may result in relevant negative social effects due mainly to the use of land for energy crops (e.g., change of food price and world food shortage.

  2. 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 emission spectrum of neat Sr 3 Tb(PO 4 ) 3 upon excitation at 337 nm in the levels above 5 D 3 is dominated by 5 D 4 emission and no significant emission from 5 D 3 is observed due to efficient cross relaxation involving the Tb 3+ levels. On the other hand, the emission spectrum of the same host containing 10 mol% Eu 3+ upon excitation at the same wavelength (in the Tb 3+ levels) is dominated by strong emission bands from the 5 D 0 level of Eu 3+ . This clearly indicates that Tb 3+ →Eu 3+ energy transfer is present. The excitation spectrum of the Eu 3+5 D 0 emission is dominated by Tb 3+ bands extending in the UV region. The presence of 10 mol% Eu 3+ in Sr 3 Tb(PO 4 ) 3 very strongly shortens the 5 D 4 decay time. The decay curve is not far from exponential, indicating that the energy transfer to Eu 3+ is accompanied by fast energy migration. The transfer regimes are identified and the donor-donor and donor-acceptor transfer microparameters are quantified under the assumption of electric dipole-electric dipole interactions. - Highlights: → Tb 3+ →Eu 3+ energy transfer in Sr 3 Tb 0.90 Eu 0.10 (PO 4 ) 3 is evidenced and investigated. → The energy migration in the 5 D 4 level of Tb 3+ is faster than the transfer to the Eu 3+ ion. → The fast migration among the Tb 3+ ions greatly enhances the transfer efficiency.

  7. High enhancement of Eu3+ luminescence in SrAl4O7 phosphor by means of charge compensation with Na+ ions

    2017-10-01

    A comparative study of the luminescent properties of SrAl4O7:Eu3+(x%) and SrAl4O7:Eu3+(x%),Na+(x%) (x = 0.002-0.1) phosphor powders as a function of activator concentration is reported. Upon UV excitation both series of compounds exhibit strong characteristic red Eu3+ photoluminescence with a maximum around 611.5 nm, which intensity increases with an increase of activator content. It was found that the luminescence spectra of singly Eu3+ doped strontium aluminate are much more concentration dependent. As the dopant content increases, the spectra of SrAl4O7:Eu3+ show an increased line broadening and the emergence of new emission components. The observed changes in the studied concentration range are due to an increased disorder of Eu3+ local symmetry induced by the increase in the number of defects in host lattice and by the presence of a new crystalline phase that occurs at the higher dopant content. Charge compensation through Na+ co-doping facilitates an incorporation of Eu3+ into the SrAl4O7 lattice and leads to a smaller symmetry disorder of activator surroundings as well as a significantly enhanced Eu3+ luminescence intensity. The largest increase in emission intensity (∼6.5 times) was observed for 7%-doped sample. Concentration dependences of the luminescence kinetics of both types of materials are clearly different. It was found that for singly Eu3+ doped SrAl4O7 the 5D0 lifetime shortens with the increase of activator content from 1.8 to 1.4 ms while for Na+ co-doped SrAl4O7 this value does not vary over a range of concentrations and is approximately 1.8 ms. SrAl4O7:Eu3+,Na+ powders are potential candidates to be used as luminescent materials.

    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.

    Ca 2 MgSi 2 O 7 :Ce 3+ , Ca 2 MgSi 2 O 7 :Eu 2+ and Ca 2 MgSi 2 O 7 :Eu 2+ ,Ce 3+ phosphors were prepared using the solid-state reaction method. The crystal structures of the sintered phosphors were of melilite type, which has a tetragonal crystallography. The chemical compositions of the sintered phosphors was confirmed by energy dispersive X-ray spectroscopy. The different thermoluminescence kinetic parameters [activation energy (E), frequency factor (s) and order of the kinetics (b)] of these phosphors were evaluated and compared using the peak shape method. Under ultraviolet excitation, the emission spectra of both Ca 2 MgSi 2 O 7 :Eu 2+ and Ca 2 MgSi 2 O 7 :Eu 2+ ,Ce 3+ phosphors were composed of a broad emission band peaking at 530 nm. When the Ca 2 MgSi 2 O 7 :Eu 2+ phosphor is co-doped with Ce 3+ ions, photoluminescence, afterglow and mechanoluminescence intensity was strongly enhanced. Ca 2 MgSi 2 O 7 :Eu 2+ showed some afterglow with a short persist time. On incorporation of Ce 3+ , efficient energy transfer from Ce 3+ to Eu 2+ was found and the emission intensity of Eu 2+ was enhanced. The mechanoluminescence intensities of Ca 2 MgSi 2 O 7 :Ce 3+ , Ca 2 MgSi 2 O 7 :Eu 2+ and Ca 2 MgSi 2 O 7 :Eu 2+ ,Ce 3+ phosphors increased proportionally increased with the increase in impact velocity, which suggests that these phosphors can be used as sensors to detect stress in an object.

    2004-12-01

    The present report is prepared as part of the project 'Poland - Electricity and gas market development study and practical guidelines for using EU - funds'. The EU structural and cohesion funds are presently considered the most relevant funds concerning support to energy projects. In general, the Polish administration of the EU structural funds is strongly decentralized. The eligible project types to be supported from the various structural funds are described in a number of sector programmes. The sector programmes are described in vertical view, meaning that it is difficult to assess what kind of energy projects are eligible for support and, if eligible, then under which programme. This report presents a horizontal view of the various programmes in order to give an overview of the possibilities of support to energy related projects. The background for this report is a study of the following sector programmes: 1. Improvement of the competitiveness of enterprises. 2. Human resources development. 3. Restructuring and modernization of food sector and rural development. 4. Fisheries and fish processing. 5. Transport - maritime economy. 6. Integrated regional operational programme. 7. Technical assistance. Based on this review, it can be stated that energy projects in general have a low priority but can be supported under various measures within the programmes. (BA)

    Full Text Available Eu-doped ZnS quantum dots (QDs have been synthesized by wet-chemical method and found to form in zinc blende (cubic structure. Both Eu2+ and Eu3+ doped ZnS can be controllably synthesized. The Eu2+ doped ZnS QDs show broad photoluminescence emission peak around 512 nm, which is from the Eu2+ intra-ion transition of 4f6d1 – 4f7, while the Eu3+ doped samples exhibit narrow emission lines characteristic of transitions between the 4f levels. The investigation of the magnetic properties shows that the Eu3+ doped samples exhibit signs of ferromagnetism, on the other hand, Eu2+ doped samples are paramagnetic of Curie-Weiss type. The incident photon to electron conversion efficiency is increased with the Eu doping, which suggests the QD solar cell efficiency can be enhanced by Eu doping due to widened absorption windows. This is an attractive approach to utilize benign and environmentally friendly wide band gap ZnS QDs in solar cell technology.

    Full Text Available When the original Rome Treaty was drafted, it was envisaged by the authors that the procedure as set out in what is now article 258 T.F.E.U. (infringement procedure would be the primary means by which EU law is enforced - a “centralized” and “public” form of enforcement assured by the ECJ, the Commission and Member States, which was itself innovative, since most international treaties contained no such mechanism. It was a point of view shared by Member States, who could see no reason why provisions of EC Treaties should be treated any differently from those of other international treaties. Thus, on the one hand, the effect of international treaties was generally governed by the principle that they cannot by themselves create rights and obligations for individuals, but only for contracting states - therefore, states were considered the only ones entitled to claim respect of international norms in international courts (individuals and national courts were excluded; on the other hand, as the text of EC treaties made no specific reference to the effect their provisions were to have, the general rule governing international treaties should also apply to them. The European Court of Justice disagreed and engaged in a prolonged judicial activism, resulting in the creation of other legal mechanisms by which national courts and individuals (rather than ECJ, Commission and Member States were to take the leading role in the enforcement of EU law - a “decentralized” and “private” form of enforcement, governed by three interrelated principles developed jurisprudentially by the ECJ: direct effect, indirect effect and state liability. In this context, the purpose of this paper is to provide an overview of actual means of EU law enforcement, as presented above; to this end, there will be considered the legal/judicial basis, scope, limits and practical difficulties of the ”centralized” and “decentralized” form of enforcement.

    In the fast-moving world of personalised medicine there are many issues and barriers-not least when it comes to getting novel drugs and treatments swiftly to where they are really needed. Slow bench-to-bedside rates do not help the 500 million potential patients across the EU's current 28 Member States, and the timings are affected by several elements during the development and licensing phases. As we all know, personalised medicine starts with the patient. It holds huge potential for improving the health of many patients and ensuring better outcomes for health systems' efficiency and transparency.

  3. EU Energy Policies Targeting the Environment

    2014-05-01

    Full Text Available Activities in the energy sector provide the greatest contribution to the emission of greenhouse gases (GHG, which are assigned primary responsibility for producing climate change. The European Union puts great emphasis on the mitigation of the environmental impact of the energy sector, in particular concerning the combat against climate change, this fact being demonstrated by the implementation of policies by the EU in this field. This paper aims to analyse the most important Community energy policies with environmental effects, such as setting of climate and energy targets for 2030, policies on nuclear and renewable energy or measures to increase energy efficiency.

    In the recently issued Opinion 2/13, the EU Court of Justice ruled that EU accession to the European Convention on Human Rights on the basis of the current Draft Accession Agreement would be incompatible with the EU Treaties. This article examines the impact of Opinion 2/13 on European fundamental...... rights protection. It argues that the concerns for EU law autonomy expressed in the Opinion for the most part are unwarranted and that the Court, through the use of classic constitutionalist language, seeks to position EU law as the superior European fundamental rights regime.

  10. Negative ion sources

    International Nuclear Information System (INIS)

    Ishikawa, Junzo; Takagi, Toshinori

    1983-01-01

    Negative ion sources have been originally developed at the request of tandem electrostatic accelerators, and hundreds of nA to several μA negative ion current has been obtained so far for various elements. Recently, the development of large current hydrogen negative ion sources has been demanded from the standpoint of the heating by neutral particle beam injection in nuclear fusion reactors. On the other hand, the physical properties of negative ions are interesting in the thin film formation using ions. Anyway, it is the present status that the mechanism of negative ion action has not been so fully investigated as positive ions because the history of negative ion sources is short. In this report, the many mechanisms about the generation of negative ions proposed so far are described about negative ion generating mechanism, negative ion source plasma, and negative ion generation on metal surfaces. As a result, negative ion sources are roughly divided into two schemes, plasma extraction and secondary ion extraction, and the former is further classified into the PIG ion source and its variation and Duoplasmatron and its variation; while the latter into reflecting and sputtering types. In the second half of the report, the practical negative ion sources of each scheme are described. If the mechanism of negative ion generation will be investigated more in detail and the development will be continued under the unified know-how as negative ion sources in future, the development of negative ion sources with which large current can be obtained for any element is expected.

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

    Recent results obtained by BABAR experiment and related to strong interactions physics are presented, with particular attention to the extraction of the first four hadronic-mass moments and the first three lepton-energy moments in semileptonic decays. From a simultaneous fit to the moments, the CKM element |V{sub cb}|, the inclusive B {yields} X{sub c}lv and other heavy quark parameters are derived. The second topic is the ambiguity-free measurement of cos(2{beta}) in B {yields} J/{Psi}K* decays. With approximately 88 million of B{bar B} pairs, negative solutions for cos(2{beta}) are excluded at 89%.

    This article outlines the current context and the development of the European Bioeconomy Strategy. It analyses the current situation, challenges and needs for EU action and concludes with the next steps that the European Commission will undertake to review and update the Bioeconomy Strategy. Bioeconomy offers great opportunities to realising a competitive, circular and sustainable economy with a sound industrial base that is less dependent on fossil carbon. A sustainable bioeconomy also contributes to climate change mitigation, with oceans, forests and soils being major carbon sinks and fostering negative CO 2 emissions. The EU has invested significantly in research and innovation in this field and the European Commission is committed to lead on European bioeconomy strategy. Copyright © 2017 Elsevier B.V.

    Polymer-based scintillator composites have been produced by combining polystyrene (PS) and Gd2O3:Eu3+ scintillator nanoparticles. Polystyrene has been used since it is a flexible and stable binder matrix, resistant to thermal and light deterioration and with suitable optical properties. Gd2O3:Eu3+ has been selected as scintillator material due to its wide band gap, high density and visible light yield. The optical, thermal and electrical characteristics of the composites were studied as a function of filler content, together with their performance as scintillator material. Additionally 1 wt.% of 2,5-diphenyloxazole (PPO) and 0.01 wt.% of 1,4 di[2-(5phenyloxazolyl)]benzene (POPOP) were introduced in the polymer matrix in order to strongly improve light yield, i.e., the measured intensity of the output visible radiation, under X-ray irradiation. Increasing scintillator filler concentration (from 0.25 to 7.5 wt.%) increases scintillator light yield and decreases the optical transparency of the composite. The addition of PPO and POPOP strongly increased the overall transduction performance of the composite due to specific absorption and re-emission processes. It is thus shown that Gd2O3:Eu3+/PPO/POPOP/PS composites with 0.25 wt.% of scintillator content with fluorescence molecules are suitable for the development of innovative large-area X-ray radiation detectors with huge demand from the industries.

  15. Changes in Policy and Market and Network Regulation to Increase Power Generation by Renewables and DG in the EU

    Van Oostvoorn, F.; Van der Welle, A.

    2009-01-01

    Recently the importance of 'Large scale DER integration' has increased as means to meet the ambitious 2020 EU policy objectives and targets for RES, emissions reductions and energy efficiency. Increasing the role of RES and DG (Renewable Energy Sources and Distributed Generation or DER) in supply is also highly beneficial for reducing EU dependency on gas and oil imports. In this EU context, it is important to review the current barriers, support policies and network regulation for integration of more DG, RES and small scale CHP (Combined Heat and Power) in the power systems. Several studies conducted for the EU and led by the ECN (Energy research Centre of the Netherlands) reveal that currently, in some, mainly new, Member States, the contribution of RES and DG is still very low. However, in coming decades the share of variable RES-E sources should become much larger in many EU countries. Note that 20% RES in a country in 2020 implies a share of electricity supply by RES of about 30% or more. Currently, countries like Denmark and Spain, already experience such a large contribution of (mostly intermittent type) renewables and this is already negatively impacting power system costs. Now the question arises whether or not we can increase the contribution of RES to the power supply beyond 20-30% without raising system inefficiency and what changes in system conditions and market and network regulation are necessary to efficiently absorb large volumes of so called intermittent RES supply resources. Based on findings from several large EU projects promoting the role of RES and DG in the power supply, the authors discuss and present the different barriers and solutions that should facilitate meeting the ambitious EU policy targets for RES in 2020

They crystallize with the EuAuGe type structure, space group Imm2. The four structures were refined from single-crystal X-ray data. The silver and indium atoms build up orthorhombically distorted, puckered Ag{sub 3}In{sub 3} hexagons, which are stacked in AA' sequence, leading to direct Ag-Ag and In-In interlayer bonding (e.g. 303 and 304 pm in CaAgIn). Temperature dependent magnetic susceptibility measurements show a magnetic moment of 7.40(1) μ{sub B} per europium atom. EuAgIn orders antiferromagnetically at 5.7(5) K.

    2009-10-01

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

    2013-04-01

    Full Text Available In March 2013, the EU and Japan launched negotiations for a comprehensive free trade agreement (FTA. The EU also announced starting of similar negotiations with the United States. Japan decided to join the Trans-Pacific Partnership under negotiation among 11 developed and developing nations in Asia-Pacific. FTAs are not new for the multilateral trading system. Striking is, however, the outstanding pace of the new trade deals among traditional trading powers. Our paper addresses the significance of the EU-Japan FTA. It first discusses the new FTA from a broader perspective, focusing on the difficulties and ongoing structural changes in the world economy. Second, it explores its importance through the lens of EU-Japan bilateral trade relations. It concludes that the recent push for FTAs by the big trading powers is a rapid means of mutual market opening in the context of reforming the very fundamentals of their economic and trade policies, as a response to the financial crisis and the shift in economic power from developed to developing countries.

It seems plausible to expect that if the negation as such is central to the meaning...... of the utterance (as in polemic negations), the negation will be articulated prominently in order to emphasise this importance. Likewise, if the negation is not central to the meaning of the utterance, it should not be articulated prominently.

    2012-12-01

    EU enlargement has facilitated the mobility of EU citizens, including health professionals, from the 2004 and 2007 EU accession states. Fears have been raised about a mass exodus of health professionals and the consequences for the operation of health systems. However, to date a systematic analysis of the EU enlargement's effects on the mobility of health professionals has been lacking. The aim of this article is to shed light on the changes in the scale of movement, trends and directions of flows pre and post 2004 and 2007 EU enlargements. The study follows a pan-European secondary data analysis to (i) quantitatively and (ii) qualitatively analyse mobility before and after the EU enlargement. (i) The secondary data analysis covers 34 countries (including all EU Member States). (ii) Data were triangulated with the findings of 17 country case studies to qualitatively assess the effects of enlargement on health workforce mobility. The stock of health professionals from the new (EU-12) into the old EU Member States (EU-15) have increased following EU accession. The stock of medical doctors from the EU-12 in the EU-15 countries has more than doubled between 2003 and 2007. The available data suggest the same trend for dentists. The extremely limited data for nurses show that the stock of nurses has, in contrast, only slightly increased. However, while no reliable data is available evidence suggests that the number of undocumented or self-employed migrant nurses in the home-care sector has significantly increased. Health professionals trained in the EU-12 are becoming increasingly important in providing sufficient health care in some destination countries and regions facing staff shortages. A mass exodus of health professionals has not taken place after the 2004 and 2007 EU enlargements. The estimated annual outflows from the EU-12 countries have rarely exceeded 3% of the domestic workforce. This is partly due to labour market restrictions in the destination countries

  6. Roles of doping ions in afterglow properties of blue CaAl2O4:Eu2+,Nd3+ phosphors

    2014-04-01

    Eu2+ doped and Nd3+ co-doped calcium aluminate (CaAl2O4:Eu2+,Nd3+) phosphor was prepared by a urea-nitrate solution combustion method at furnace temperatures as low as 500 °C. The produced CaAl2O4:Eu2+,Nd3+ powder was investigated in terms of phase composition, morphology and luminescence by X-Ray diffraction (XRD), Scanning Electron Microscope (SEM), Fourier Transform Infra Red spectroscopy (FTIR) and Photoluminescence (PL) techniques respectively. XRD analysis depicts a dominant monoclinic phase that indicates no change in the crystalline structure of the phosphor with varying concentration of Eu2+ and Nd3+. SEM results show agglomerates with non-uniform shapes and sizes with a number of irregular network structures having lots of voids and pores. The Energy Dispersive X-ray Spectroscopy (EDS) and (FTIR) spectra confirm the expected chemical components of the phosphor. PL measurements indicated one broadband excitation spectra from 200 to 300 nm centered around 240 nm corresponding to the crystal field splitting of the Eu2+ d-orbital and an emission spectrum in the blue region with a maximum on 440 nm. This is a strong indication that there was dominantly one luminescence center, Eu2+ which represents emission from transitions between the 4f7 ground state and the 4f6-5d1 excited state configuration. High concentrations of Eu2+ and Nd3+ generally reduce both intensity and lifetime of the phosphor powders. The optimized content of Eu2+ is 1 mol% and for Nd3+ is 1 mol% for the obtained phosphors with excellent optical properties. The phosphor also emits visible light at around 587 and 616 nm. Such emissions can be ascribed to the 5D0-7F1 and 5D0-7F2 intrinsic transition of Eu3+ respectively. The decay characteristics exhibit a significant rise in initial intensity with increasing Eu2+ doping concentration while the decay time increased with Nd3+ co-doping. The observed afterglow can be ascribed to the generation of suitable traps due to the presence of the Nd3

  7. 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.

    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)

    An orange-emitting phosphor, Eu(2+)-activated LiSr4(BO3)3, was synthesized using the conventional solid-state reaction. The photoluminescence excitation and emission spectra, and temperature dependence of the luminescence intensity of the phosphor were investigated. The results showed that LiSr4(BO3)3:Eu(2+) could be efficiently excited by incident light of 250-450 nm, and emits a strong orange light. With increasing temperature, the emission bands of LiSr4(BO3)3:Eu(2+) show an abnormal blue-shift with broadening bandwidth and decreasing emission intensity.

    Titanium (Ti) is a strong silver-gray metal that is highly resistant to corrosion and is chemically inert. It is as strong as steel but 45 percent lighter, and it is twice as strong as aluminum but only 60 percent heavier. Titanium dioxide (TiO2) has a very high refractive index, which means that it has high light-scattering ability. As a result, TiO2 imparts whiteness, opacity, and brightness to many products. ...Because of the unique physical properties of titanium metal and the whiteness provided by TiO2, titanium is now used widely in modern industrial societies.

    The (Eu, La, Sm) ions were doped into ZnO nanoparticles by a chemical route, and the substitution of (Eu, La, Sm) for Zn{sup 2+} ions was proved by analytic techniques of X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Raman, transmission electron microscope (TEM), photoluminescence (PL) and UV–vis absorption spectroscopy. The results revealed that the codoping did not change the wurtzite structure of ZnO nanoparticles, but the diameter of the nanoparticles decreased with increasing the rare earth (RE) doping concentrations. The optical bandgaps calculated through UV–visible absorption spectroscopy were found to decrease from 3.26 to 3.14 eV with increasing the RE doping concentrations, which also proved by the slight shift of UV positions in PL spectra. The sharp red emissions located at 578.2, 590.1 and 615.7 nm were originated from the 4f-4f transitions in Eu{sup 3+} ions under excitation of 325 nm. And these red emissions of Eu{sup 3+} ions showed a strong correlation with the energy storage centers of oxygen vacancies in the samples which was introduced by the other RE ions of La{sup 3+} and Sm{sup 3+} codoping. - Highlights: • Doping of (Eu, La, Sm) ions into ZnO nanoparticles is realized by a chemical route. • Eu{sup 3+}-related red emissions from intra-4f follow a similar trend as broad defect emission. • Red emissions of Eu{sup 3+} enhance with RE codoping due to oxygen vacancies as energy storage centers. • The bandgap can be tuned by RE codoping, which shows a prospect for the visible utilization.

    The efficiency of Eu3+ luminescence by energy transfer from an antenna ligand can be strongly dependent on the metal ion coordination geometry. The geometric component of the Eu(III) sensitization has been probed using series of tetradentate 1,2-HOPO derivatives that are connected by bridges of varying length and geometry. The ligands are N,N'-(1,2-phenylene)bis(1-hydroxy-6-oxo-1,6-dihydropyridine-2-carboxamide) for the ligand (L{sup 1}), 1-hydroxy-N-(2-(1-hydroxy-6-oxo-1,6-dihydropyridine-2-carboxamido)benzyl)-6-oxo-1,6-dihydropyridine-2-carboxamide (L{sup 2}) and N,N'-(1,2-phenylenebis(methylene))bis(1-hydroxy-6-oxo-1,6-dihydropyridine-2-carboxamide) (L{sup 3}). Spectroscopic characterization of both the Gd(III) and Eu(III) metal complexes, TD-DFT analysis of model compounds and evaluation of the kinetic parameters for the europium emission were completed. Some striking differences were observed in the luminescence quantum yield by altering the bridging unit. The [Eu(L{sup 2}){sub 2}]{sup -} derivative shows efficient sensitization coupled with good metal centered emission. For [Eu(L{sup 3}){sub 2}]{sup -}, the large quenching of the luminescence quantum yield compared to [Eu(L{sup 2}){sub 2}]{sup -} is primarily a result of one inner sphere water molecule bound to the europium cation while for [Eu(L{sup 1}){sub 2}]{sup -}, the low luminescence quantum yield can be attributed to inefficient sensitization of the europium ion.

    The five-year value in the compound annual growth rate of the biopesticides sector is predicted to be 16% by 2017 and to produce a global market worth $US 10 billion. Despite this, several impediments occur within the EU that negatively affect biopesticide research and innovation. At present, there are fewer biopesticide-active substances registered in the EU compared with the United States, India, Brazil and China. The relatively low level of biopesticide research in the EU (6880 ISI papers) versus the United States (18 839), India (9501) and China (7875) relates to the greater complexity of EU-based biopesticide regulations compared with these other countries. In this light, it is worth noting that tensions may exist between regulators that emphasise the beneficial nature of biopesticides in environmentally friendly crop management and those that adopt a more technologically based approach dependent on a chemical-pesticide-driven model. Compared with the other aforementioned countries, far fewer biopesticide products are available in the EU market, mainly as a direct result of the severe regulatory factors present there. The extent to which this trend will continue depends largely on a range of interacting political and/or regulatory decisions that influence environmentally friendly agricultural industries. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    The sorption mechanisms of Eu(3+) on calcium silicate hydrate (CSH) phases of hydrated cement were investigated as a tool for the prediction of the behavior of trivalent radionuclides with aged/degraded cements in radioactive waste repositories. Four techniques were used: site-selective and time-resolved luminescence spectroscopy, XPS, high-resolution SEM coupled with EDX, and XRD. Results showed that europium is not precipitated in the solution despite its low solubility limit. It is strongly retained on CSH, resulting in a more than 99.8% sorption rate. Two main sorption sites were characterized by luminescence spectroscopy. One site, with a long lifetime, can be interpreted as Eu included in the framework of CSH. Another one, with a shorter lifetime, can be interpreted as a site with a hydrated environment that is high but is less than that of europium hydroxide. It corresponds to superficial complexation or precipitation. Copyright 2001 Academic Press.

  18. New opportunities for EU projects at CERN

    2009-01-01

    In July 2009 the European Commission (EC) finalised how it will spend research funding for 2010, within its Framework Programme 7 (FP7). On 31 July the EC is expected to publish new calls for European project proposals, many of which are relevant to CERN. In the first two and a half years of Framework Programme 7 (2007-2013), CERN has been very successful – the Organization is participating in around 30 EU projects, with total EC contribution of nearly 35 million Euros. The now finalised 2010 Work Programmes for FP7 outline how the EC will allocate budgets within each research field. From these Work Programmes, a series of calls for proposals are published so researchers can apply for targeted funding within given deadlines. The first calls are expected to be launched on 31 July and closed later in the year. The web-site of the CERN EU Projects Office contains a list of all new calls of potential interest to CERN, as well as the relevant Work Programmes and Guide for A...

  19. REFUEL: an EU road map for biofuels

    2007-05-15

    A successful mid-term development of biofuels calls for a robust road map. REFUEL assesses inter alia least-cost biofuel chain options, their benefits, outlines the technological, legislative and other developments that should take place, and evaluate different policy strategies for realisation. Some preliminary conclusions of the project are discussed here. There is a significant domestic land potential for energy crops in the EU, which could supply between one quarter and one third of gasoline and diesel demand by 2030 if converted into advanced biofuels. A biomass supply of 8 to 10 EJ of primary energy could be available at costs around or below 3 EURO/GJ. However, the introduction of advanced biofuel options may meet a considerable introductory cost barrier, which will not be overcome when EU policy is oriented to the introduction of biofuels at least cost. Therefore, conventional biodiesel and ethanol may dominate the market for decades to come, unless biofuels incentives are differentiated, e.g. on the basis of the differences in greenhouse gas performance among biofuels.The introduction of advanced biofuels may also be enhanced by creating stepping stones or searching introduction synergies. A stepping stone can be the short-term development of lignocellulosic biomass supply chains for power generation by co-firing; synergies can be found between advanced FT-diesel production and hydrogen production for the fuel cell.

    The reimbursement landscape for new and innovative diabetes devices in Europe is very heterogeneous and nontransparent, with each country employing different mechanisms, pathways, and requirements. This article provides an overview of how diabetes device reimbursement works in the outpatient setting in the five major European Union markets (France, Germany, Italy, Spain, and the United Kingdom; the EU-5). It will be of particular interest to manufacturers of innovative devices. Markets are first categorized as either a centralized or a regionalized reimbursement decision-making system, and implications for device reimbursement are explored. In the second part, specific requirements and success factors for wide reimbursement in the EU-5 are analyzed in detail. Gaining early acceptance by the main influencers (key opinion leaders and payers) is the first step. Equally important is the provision of convincing evidence, be this clinical, health-economic (cost-effectiveness), or a demonstration of cost savings (budget impact). In some countries, local usage data may be a requirement as well. Lastly, as payers' willingness to pay stems directly from their perceived value of a device, a key success factor and a necessary precondition for manufacturers is to set the right price. © 2013 Diabetes Technology Society.

    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.

  3. Highly luminescent colloidal Eu(3)+-doped KZnF(3) nanoparticles for the selective and sensitive detection of Cu(II) ions.

    2014-03-17

    This article describes a green synthetic approach to prepare water dispersible perovskite-type Eu3+-doped KZnF3 nanoparticles, carried out using environmentally friendly microwave irradiation at low temperature (85 8C) with water as a solvent. Incorporation of Eu3+ ions into the KZnF3 matrix is confirmed by strong red emission upon ultraviolet (UV) excitation of the nanoparticles. The nanoparticles are coated with poly(acrylic acid) (PAA), which enhances the dispersibility of the nanoparticles in hydrophilic solvents. The strong red emission from Eu3+ ions is selectively quenched upon addition of CuII ions, thus making the nanoparticles a potential CuII sensing material. This sensing ability is highly reversible by the addition of ethylenediaminetetraacetic acid (EDTA), with recovery of almost 90% of the luminescence. If the nanoparticles are strongly attached to a positively charged surface, dipping the surface in a CuII solution leads to the quenching of Eu3+ luminescence, which can be recovered after dipping in an EDTA solution. This process can be repeated for more than five cycles with only a slight decrease in the sensing ability. In addition to sensing, the strong luminescence from Eu3+-doped KZnF3 nanoparticles could be used as a tool for bioimaging.

    2010-01-01

    Full Text Available A phosphorescent material in the form of Y2O2S:Eu3+, Mg2+, Ti4+ hollow microspheres was prepared by homogeneous precipitation using monodispersed carbon spheres as hard templates. Y2O3:Eu3+ hollow microspheres were first synthesized to serve as the precursor. Y2O2S:Eu3+, Mg2+, Ti4+ powders were obtained by calcinating the precursor in a CS2 atmosphere. The crystal structure, morphology and optical properties of the composites were characterized. X-ray diffraction measurements confirmed the purity of the Y2O2S phase. Electron microscopy observations revealed that the Y2O2S:Eu3+, Mg2+, Ti4+ particles inherited the hollow spherical shape from the precursor after being calcined in a CS2 atmosphere and that they had a diameter of 350–450 nm and a wall thickness of about 50–80 nm. After ultraviolet radiation at 265 or 325 nm for 5 min, the particles emitted strong red long-lifetime phosphorescence originating from Eu3+ ions. This phosphorescence is associated with the trapping of charge carriers by Ti4+ and Mg2+ ions.

    (Y0.99Eu0.01)2O3 nanoceramics have been produced by sintering of stable cubic nanopowders under 8 GPa at temperature in the range of 25-500 °C with the use of Low Temperature High Pressure (LTHP) technique. During consolidation step irreversible phase transition from cubic to monoclinic yttria occurs resulting in two-phase nanoceramics with a grain size in the 10-40 nm range. It has been demonstrated that composite nanoceramics possess a high transmittance in the visible and mid IR ranges due to small light scattering on the nanoscale pores and low birefringence due to extremely small grain size. It has been shown that Eu3+ ions act as a luminescent probe in composite (Y0.99Eu0.01)2O3 nanoceramics since their 4f-4f luminescence strongly depends on the crystallographic environment. The luminescence spectra excited in the charge transfer band (CTB) are presented by superposition of emission from europium ions in cubic and monoclinic yttria. A new wide emission band of (Y0.99Eu0.01)2O3 ceramics in the λ = 500-650 nm wavelengths range (λex. = 307 nm) were attributed to luminescence of Eu3+ ions located in perturbed sites at grain boundaries or interfaces.

  7. Effectiveness of EU Conditionality in the Western Balkans: Minority Rights and the Fight Against Corruption in Croatia and Macedonia

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available EU candidate countries must prove their respect for democracy and the rule of law to be eligible for EU membership. The Commission administers their accession processes following the principle of conditionality. This paper examines how domestic conditions and different aspects of the conditionality principle affect policy outcomes. It reviews the arguments made in the literature on EU conditionality and applies them to the policy areas of minority rights and the fight against corruption in Croatia and Macedonia. Both countries have been subjected to the Commission’s conditionality while their democratic achievements differ substantially. Thereby, the two countries offer a fruitful ground to evaluate the lessons drawn from the 2004-07 enlargement. While previous studies have remained quite unclear about the relative importance of domestic and EU-related determinants of effective conditionality, I argue that domestic influences vary strongly across the researched policy areas. In comparison, the political-legal instruments of the Commission show clear impacts on policies in candidate countries. Material incentives offered by the EU are only effective within the early phases of the accession process.

    Single crystals of GdCa{sub 4}O(BO{sub 3}){sub 3} (GdCOB) pure and doped with Eu concentration of 1 and 4 at% were grown by the Czochralski and micropulling-down methods. The distribution of Eu ions in GdCOB crystals was uniform. The substitutions of Eu{sup 3+} in Gd, Ca(1) and Ca(2) cation sites and eventually formation Eu{sup 2+} have been investigated. The spectroscopic properties of crystals are compared with the properties of nanopowders obtained by sol-gel method. Radioluminescence spectra of undoped GdCOB crystal show the characteristic emission of Gd{sup 3+} at about 312 nm, whereas this emission dramatically decreases in Eu-doped crystals upon X-ray excitation, as well as in Eu-doped nanopowders excited in vacuum ultraviolet (VUV) region. The VUV excitation in the range 125-333 nm for Eu-doped samples leads to strong emission in red coming from the {sup 5}D{sub 0} multiplet of Eu{sup 3+}, only. In the photoluminescence decay kinetics of 312 nm emissions substantial shortening and departure for single exponential decay in Eu-doped samples is clearly observed. Higher Eu doping results in further acceleration of the decay. In undoped GdCOB crystal, the lifetime of the Gd{sup 3+} {sup 6}P{sub 7/2} multiplet is 2.79 ms. The Eu{sup 3+} {sup 5}D{sub 0} decay kinetics monitored at 613 nm are rather constant. Numerical fitting of fully exponential curves, reveals lifetimes 2.7 ms for nanopowder and 2.5 ms for single crystal. The results suggest that this material may be used as a red phosphor in plasma display panels in nanopowder form because of strong excitation band of Eu{sup 3+} luminescence in the 160-200 nm regions. Contrary to nanopowder sample, such an excitation band, attributed to the Gd{sup 3+}-O{sup 2-} charge transfer was not observed in crystal obtained by the micropulling-down method.

    Full Text Available The purpose of the present paper is to gauge the main trends in the evolution and structure of the EU trade in goods, mainly after 2004, starting from a quantitative analysis and comparing trends in the trade in goods with trends in the trade in services, where necessary. We focus on the trade of the EU-27 as a group, but we stress the differences and similarities between the old member states (EU- 15 and the new member states (NMS as well. Structured in seven parts, the paper reveals several noteworthy conclusions. Firstly, the EU remains the world trade leader; nevertheless, its market shares have been diminishing in the recent years, both in the export and import flows, due to a complex of factors. Secondly, the NMS shares in the EU trade flows have been growing; yet, the NMS shares in the exports and imports of the EU-27 remain at a very low level. Besides, the normalized trade balance of the NSM, compared with that of the EU-15 underlines the different competitive advantages of the two groups. Thirdly, the trade deficit of the EU-27 continues to deepen (the extra-EU trade deficit tripled in 2004-2008; however, there are significant differences between the manufactures trade balance (with large surpluses and the commodities trade balance (with a deficit that doubled between 2004 and 2008. Fourth, the paper points out that the extra-EU exports and the imports are dominated by the manufactures; however the share of manufactures in the import flows is much smaller than that in the export flows. Finally, the present analysis traces evidence of the major impact of the global financial and economic crisis on the EU trade flows and the first signs of recovery.

    Full Text Available The study presented here is aimed at analyzing the comparative advantages in the European clothing sector with the focus on Balkan states. The dynamics of change over a 15‐year period following economic reforms are revealed. For all Balkan countries export plays an important role in promoting economic growth and development and the clothing industries play a significant role and continue to contribute to the economic prosperity in this countries. The evolution of the RCA index for garment industry is decreasing for all countries in the Balkans. The evolution of the Lafay index is also decreasing in the most Balkan countries (except Greece, Montenegro and Slovenia but still the values for Lafay index is positive what indicating that in these countries the sale of garments contribute positively to balance the trade balance of countries analyzed. Negative value of the Lafay index may be due to the fact that the garment industry is one of the key industries in the economy of that country and also because the earnings from garment industry in these countries is high. When the producers of the Balkan countries will create products with higher added value in garment industry the competitiveness of these countries will decrease. Also rising wages in this industry, as a result of trade union pressure or government policy, will lead to decreasing competitiveness of these products on the EU market and implicitly to the decrease of exports of garments from these countries.

We use the EU KLEMS database for growth accounting and a broad set of indicators of labour regulations, covering two distinct 'areas' of labour regulation: employment laws and collective relations laws. This comprehensive approach allows us to consider arrangements that regulate allocation of labour inputs (fixed-term and part-time contracts, hours worked and the payoff and decision rights of employees. We find that, since 1995, European countries have not followed similar patterns of growth. A large number of variations between European economies are caused by marked differentials in multifactor productivity and part of this heterogeneity is caused by sectoral diversities. We show that, in labour-intensive sectors such as services, fixed-term contracts, which imply shorter-term jobs and lower employment tenures, may discourage investment in skills and have detrimental effects on multifactor productivity increases. Employment protection reforms which slacken the rules of fixed-term contracts cause potential drawbacks in terms of low productivity gains. We also find that more stringent regulation of these practices, as well as a climate of collective relations, sustain long-term relationships and mitigate these negative effects

    The emphasis in this chapter is on the future of EU public diplomacy in a more globalised, mulitipolar, multilateral world. The chapter does not seek to explore the role of EU member states within this future shift but clearly, as Mai’a Davis Cross discusses in her chapter, if the EU and its member...... states are to have a future role at all, they must develop synergies not antergies in external actions and public diplomacy. As the next five sections set out, this fundamental shift in the role of the EU in global politics requires a recognition of how the EU has ‘“gone global’” (section II); how EU...... diplomacy is ‘“going public’” (section III); and how EU public diplomacy needs to consider ‘“sharing minds’” (section IV); how the normative power of public diplomacy can ensure the EU is ‘“remaining distinctive’” in global politics (section V); and before concluding on the normative power approach...

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

    International Nuclear Information System (INIS)

    Norton, M.V.

    1994-03-01

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

  8. Solar Energy: Incentives to Promote PV in EU27

    Directory of Open Access Journals (Sweden)

    María del P. Pablo-Romero

    2013-11-01

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

    International Nuclear Information System (INIS)

    Yakovlev, V.; Trefilova, L.; Karnaukhova, A.; Ovcharenko, N.

    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
