From constituents to syntax-oriented dependencies

This paper describes the automatic process of building a dependency annotated corpus based on Ancora constituent structures. The Ancora corpus already has a dependency structure information layer, but the new annotated data applies a purely syntactic orientation and offers in this way a new resource to the linguistic research community. The paper details the process of reannotating the corpus, the linguistic criteria used and the obtained results.

Feasibility of electrochemical chloride extraction from structural reinforced concrete using a sprayed conductive graphite powder–cement paste as anode

This article summarizes research on the application of a conductive cement paste as an anode in the now classical technique of electrochemical extraction of chlorides applied to a concrete structural element by spraying the paste on the surface of a concrete structural element, a pillar. Sprayed conductive cement paste, by adding graphite powder, is particularly useful to treat sizable vertical surfaces such are structural supports. Outcomes indicate that this kind of anode not only provides electrochemical chloride removal with similar efficiency, but also is able to retain moisture even without the use of a continuous dampening system.

Nitrate reduction at Pt(1 0 0) single crystals and preferentially oriented nanoparticles in neutral media

The electroreduction of nitrate on Pt(1 0 0) electrodes in phosphate buffer neutral solution, pH 7.2, is reported. The sensitivity of the reaction to the crystallographic order of the surface is studied through the controlled introduction of defects by using stepped surfaces with (1 0 0) terraces of different length separated by monoatomic steps, either with (1 1 1) or (1 1 0) symmetry. The results of this study show that nitrate reduction occurs mainly on the well defined (1 0 0) terraces in the potential region where H adsorption starts to decrease, allowing the nitrate anion to access the surface. Adsorbed NO has been detected as a stable intermediate in this media. An oxidation process observed at 0.8 V has been identified as leading to the formation of adsorbed NO and being responsible for a secondary reduction process observed in the subsequent negative scan. Using in situ FTIRS, ammonium was found to be the main product of nitrate reduction. This species can be oxidized at high potentials resulting in adsorbed NO and nitrate (probably with nitrite as intermediate).

Study of the emissions from pyrolytic and oxidative thermal decomposition of PVC

Polyvinyl chloride (PVC) is one of the plastics most extensively used due to its versatility. The demand of PVC resin in Europe during 2012 reached 5000 ktonnes1. PVC waste management is a big problem because of the high volume generated all over the world and its chlorine content. End-of-life PVC is mainly mixed with municipal solid waste (MSW) and one common disposal option for this is waste-to-energy incineration (WtE). The presence of plastics such as PVC in the fuel mix increases the heating value of the fuel. PVC has two times higher energy content than MSW ‒around 20 MJ/kg vs 10 MJ/kg, respectively. However, the high chlorine content in PVC resin, 57 wt.%, may be a source for the formation of hazardous chlorinated organic pollutants in thermal processes. Chlorine present in the feedstock of WtE plants plays an important role in the formation of (i) chlorine (Cl2) and (ii) hydrochloric gas (HCl), both of them responsible for corrosion, and (iii) chlorinated organic pollutants2. In this work, pyrolytic and oxidative thermal degradation of PVC resin were carried out in a laboratory scale reactor at 500 ºC in order to analyze the influence of the reaction atmosphere on the emissions evolved. Special emphasis was put on the analysis of chlorinated organic pollutants such as polychlorodibenzo-p-dioxins (PCDDs), polychlorodibenzofurans (PCDFs) and other related compounds like polychlorobenzenes (PCBzs), polychlorophenols (PCPhs) and polycyclic aromatic hydrocarbons (PAHs). Another objective of this work was to compare the results with those of a previous work3 in which emissions at different temperatures in both pyrolysis and combustion of another PVC resin had been studied; in that case, experiments for PCDD/Fs emissions had been performed only at 850 ºC.

Synthesis of palladium nanoparticles over graphite oxide and carbon nanotubes by reduction in ethylene glycol and their catalytic performance on the chemoselective hydrogenation of para-chloronitrobenzene

Pd nanoparticles have been synthesized over carbon nanotubes (CNT) and graphite oxide (GO) by reduction with ethylene glycol and by conventional impregnation method. The catalysts were tested on the chemoselective hydrogenation of p-chloronitrobenzene and the effect of the synthesis method and surface chemistry on their catalytic performance was evaluated. The catalysts were characterized by N2 adsorption/desorption isotherms at 77 K, TEM, powder X-ray diffraction, thermogravimetry, infrared and X-ray photoelectron spectroscopy and ICP-OES. It was observed that the synthesis of Pd nanoparticles employing ethylene glycol resulted in metallic palladium particles of smaller size compared to those prepared by the impregnation method and similar for both supports. The presence of oxygen groups on the support surface favored the activity and diminished the selectivity. It seems that ethylene glycol reacted with the surface groups of GO, this favoring the selectivity. The activity was higher over the CNT-based catalysts and both catalysts prepared by reduction in ethylene glycol were quite stable upon recycling.

The European Court of Justice and process-oriented review. Research Paper in Law, 01/2012

Structuralism is a theory of U.S. constitutional adjudication according to which courts should seek to improve the decision-making process of the political branches of government so as to render it more democratic.1 In words of John Hart Ely, courts should exercise their judicial-review powers as a ‘representation-reinforcing’ mechanism.2 Structuralism advocates that courts must eliminate the elements of the political decision-making process that are at odds with the structure set out by the authors of the U.S. Constitution. The advantage of this approach, U.S. scholars posit, lies in the fact that it does not require courts to second-guess the policy decisions adopted by the political branches of government. Instead, they limit themselves to enforcing the constitutional structure within which those decisions must be adopted. Of course, this theory of constitutional adjudication, like all theories, has its shortcomings. For example, detractors of structuralism argue that it is difficult, if not impossible, to draw the dividing line between ‘substantive’ and ‘structural’ matters.3 In particular, they claim that, when identifying the ‘structure’ set out by the authors of the U.S. Constitution, courts necessarily base their determinations not on purely structural principles, but on a set of substantive values, evaluating concepts such as democracy, liberty and equality. 4 Without claiming that structuralism should be embraced by the ECJ as the leading theory of judicial review, the purpose of my contribution is to explore how recent case-law reveals that the ECJ has also striven to develop guiding principles which aim to improve the way in which the political institutions of the EU adopt their decisions. In those cases, the ECJ decided not to second-guess the appropriateness of the policy choices made by the EU legislator. Instead, it preferred to examine whether, in reaching an outcome, the EU political institutions had followed the procedural steps mandated by the authors of the Treaties. Stated simply, I argue that judicial deference in relation to ‘substantive outcomes’ has been counterbalanced by a strict ‘process review’. To that effect, I would like to discuss three recent rulings of the ECJ, delivered after the entry into force of the Treaty of Lisbon, where an EU policy measure was challenged indirectly, i.e. via the preliminary reference procedure, namely Vodafone, Volker und Markus Schecke and Test-Achats.5 Whilst in the former case the ECJ ruled that the questions raised by the referring court disclosed no factor of such a kind as to affect the validity of the challenged act, in the latter cases the challenged provisions of an EU act were declared invalid.

A stronger, growth-oriented surveillance for EMU. EuropEos Commentary No. 1, 19 April 2010

This Commentary finds that the recent adjustment measures taken by the Greek government in combination with the financial support proffered by the Eurogroup may not be sufficient to deal with the risk of instability in EMU in the longer term. The author argues that other imbalances, most notably the current account imbalances within EMU, need to be addressed to avoid a deflation spiral that would aggravate sustainability problems in highly indebted countries. The Greek crisis highlights the need to take steps to strengthen the economic governance of the euro area. A key component of these steps would be a stronger, growth-oriented, surveillance.

The CAP post-2013: more equitable, green and market-oriented? Based on the seminar held by Egmont on the 25th of November. European Policy Brief No. 5, December 2011

Following a seminar on the CAP post- 2013 held by Egmont - with the cooperation of the Polish Presidency - on the 25th of November 2011, Egmont commissioned the present policy brief. Three major policy issues were addressed at this occasion, namely; how to make the CAP more equitable, green and market-oriented? The trade-off between these policy issues will require policy choices that are worthy of analysis.

Modello activity oriented per la gestione della radioprotezione di una azienda sanitaria

Alla base delle analisi di radioprotezione di una azienda sanitaria si potrebbero considerare quattro settori da cui partire: le attività svolte che presentano un rischio dal punto di vista radiologico, gli apparecchi radiogeni, i locali all'interno del quale si svolgono le attività e infine i lavoratori, che devono essere classificati o meno in base ai valori di dose efficace a cui vengono esposti. In questo elaborato si vuole presentare un nuovo modello informatico di gestione, definito activity-oriented perché volto a portare le attività al centro dell'indagine di radioprotezione così da poter strutturare di conseguenza anche i dati relativi ad apparecchiature, locali e lavoratori, in modo da avere un visione completa dell’azienda così da facilitarne il monitoraggio. Tale modello è stato creato negli ultimi anni nell’azienda USL di Forlì e contemporaneamente è stato sviluppato un software che permette di automatizzare parte dei lavori di competenza dell’Esperto Qualificato. Applicando tali strumenti sull’Azienda USL della Romagna Area Territoriale di Ravenna è stato possibile passare da una gestione cartacea, priva di modellizzazione informatica, ad una gestione basata sul concetto di attività a rischio radiologico. Verranno evidenziati i passaggi che sono stati necessari per un corretto adattamento dello schema e inoltre verranno presentati i risultati ottenuti. In conclusione si vuole evidenziare come il modello descritto permetta una consistente riduzione del tempo necessario per svolgere le attività di competenza dell'Esperto Qualificato, riducendo inoltre gli errori commessi. Si ha così un guadagno di tempo impiegabile per formare i lavoratori classificati sui rischi che ci sono lavorando con radiazioni ionizzanti e quali possono essere le opportune precauzioni da utilizzare.
