The Gulf of Corinth is one of the fastest-spreading intra-continental rifts on Earth. GPS data indicate that the rift is currently opening in a NNE-SSW direction, with a rate of extension reaching up to 16 mm yr-1 in its westernmost part. Although the rest of the offshore rift has been well studied, the western tip of the rift is still poorly explored. We present an accurate map of submarine faults in this area based on two high-resolution seismic reflection surveys (single channel sparker). In the eastern part of the studied area, the sedimentary infill is affected by the known North Eratini, South Eratini and West Channel faults. Further to the west, the seafloor is mostly flat, and is bounded to the north by the normal, south-dipping, Trizonia fault. To the north, the shallower part of the Gulf shows to the east a diffuse pattern of normal and strike-slip deformation which is replaced to the west by a 7.5 km long SE striking strike-slip fault zone, called the Managouli fault zone. To the westernmost tip of the Gulf, in the Nafpaktos Basin, two fault sets with different strikes are encountered; the one with aNE-SW strike exhibits a clear strike-slip component. The western tip of the Gulf of Corinth is the only part of the Corinth Rift where convincing evidence for strike-slip movement has been found. This fault pattern is likely related to the complex deformation occurring at the diffuse junction at the western tip of the Rift between three crustal blocks: Continental Greece, Peloponnese, and the Ionian Island-Akarnia block.

BACKGROUND: Adult cardiac surgery is significantly associated with the development of acute kidney injury (AKI). Still, the incidence and outcomes of AKI vary according to its definition. Our retrospective monocentric study comparatively investigates the yield of RIFLE definition, which is based on the elevation of serum creatinine levels (SCr) or the reduction of urine output (UO), taking into account only one or both criteria. Pre- and per-operative risk factors for post-operative AKI were evaluated. METHODS: All adult patients undergoing cardiac surgery, with or without cardiopulmonary bypass, from April 2008 to March 2009 were included. Clinical, biological and surgical features were recorded. Baseline serum creatinine was determined as its value on day 7 before surgery. Post-operative AKI was diagnosed and scored based upon the highest serum creatinine and/or the lowest urine output. RESULTS: 443 patients (Male/Female ratio, 2.3; median age, 69y) were included, with 221 (49.9 %) developing postoperative AKI. Elevated serum creatinine (AKISCr) and oliguria (AKIUO) was observed in 9.7 % and 40.2 %, respectively. AKI patients had a significantly higher BMI and baseline SCr. In comparison to AKIUO, AKISCr mostly occurred in patients with co-morbidities, and was associated with an increased mortality at 1-year post surgery. CONCLUSIONS: The use of standard RIFLE definition of AKI in a cohort of 443 patients undergoing cardiac surgery resulted in an incidence reaching 50 %. Still, significant discrepancies were found between AKISCr and AKIUO regarding the incidence and outcomes. In line with previous reports, our data questions the utility of urine output as a criterion for AKI diagnosis and management after cardiac surgery. [less ▲]

Patients admitted to critical care often experience dysglycemia and high levels of insulin resistance, various intensive insulin therapy protocols and methods have attempted to safely normalize blood glucose (BG) levels. Continuous glucose monitoring (CGM) devices allow glycemic dynamics to be captured much more frequently (every 2-5 minutes) than traditional measures of blood glucose and have begun to be used in critical care patients and neonates to help monitor dysglycemia. In an attempt to obtain a better insight relating biomedical signals and patient status, some researchers have turned toward advanced time series analysis methods. In particular, Detrended Fluctuation Analysis (DFA) has been a topic of many recent studies in to glycemic dynamics. DFA investigates the "complexity" of a signal, how one point in time changes relative to its neighboring points, and DFA has been applied to signals like the inter-beat-interval of human heartbeat to differentiate healthy and pathological conditions. Analyzing the glucose metabolic system with such signal processing tools as DFA has been enabled by the emergence of high quality CGM devices. However, there are several inconsistencies within the published work applying DFA to CGM signals. Therefore, this article presents a review and a "how-to" tutorial of DFA, and in particular its application to CGM signals to ensure the methods used to determine complexity are used correctly and so that any relationship between complexity and patient outcome is robust.

During the XX century European administrative systems have undergone a profound process of managerial revolution during which private sector managerial tools and principles have spread across both central and local governments in many countries. As many scholars have associated this process of change with the raise and diffusion of a managerialist ideology, this paper empirically investigates the electoral propaganda that since 1950s has supported the diffusion of managerialist values across the national administrative systems of the European countries. On the basis of a longitudinal study of the electoral programs released by the European parties since 1950s, this research provides evidence-based knowledge about: i) the different patterns of diffusion of the public-sector managerialist propaganda in Eastern and Western Europe; ii) the controversial relationship that exists between the spread of the managerialist ideology and the actual adoption of managerialist reforms in the national structures of the public sector.

In the aftermath of the worst financial and economic crisis in generations, the modernization of public administrations of the EU’s Member States (MSs) is among the structural reforms recommended by the European Commission to relaunch growth in the European economy. This type of reforms has a longstanding tradition in the MSs as they sharply intensified during the 1990s following the paradigm of New Public Management (NPM). Indeed, by backing NPM-style reforms, the European Commission has fostered convergence between the administrative systems of the MSs based on a soft strategy of integration where, instead of establishing binding pan-European rules enforced directly in all the MSs, it has set a number of regulatory standards implemented in the MSs with the support of national legislators and political parties. This paper empirically addresses the above-mentioned process of soft integration by unveiling the domestic determinants that have led MSs’ political parties to call for NPM-style reforms in their national contexts between 1997 and 2011. The hypothesis tested in this study is that MSs’ political parties have called for NPM-style reforms in order to respond to specific challenges issuing from the macro-economic, institutional and political configuration of their domestic contexts. The contribution of this paper is twofold. On the one hand, it contributes to a better understanding of the process of European administrative integration by providing robust empirical evidence about the patterns of diffusion NPM-style reforms across the MSs of the EU. On the other hand, the empirical evidence provided by this paper for the comprehension of NPM-style reforms in the context of the EU also contributes to a better understanding of some traditional theories addressing the reasons of the worldwide striking international trend of the NPM paradigm.

The prediction of the shear resistance of connections as presently given in Eurocode 3, Part 1-8, cannot be applied in a straightforward way to the connection for tubular racking structures realized by means of long through bolts. In order to verify the possibility to extend the codified approach to such joint configurations, in the present paper a finite element model with three-dimensional solid elements is established investigating the behaviour of the connections under shear load in a wide range of variability of the geometrical parameters. The validation of the numerical model has been performed starting from the results of experimental tests already performed by the authors at the laboratory on Materials and Structures of the University of Liège. Based on the finite element results, the load displacement curves for all the assemblies were successfully predicted evidencing the important role played by the hole’s geometry and reduced diameter of the bolts on the initial stiffness of the connections. The results of a parametric study by means of a calibrated FE model in Abaqus/CAE allowed to verify the possibility to extend the formulations provided by EC3 for predicting the bearing resistance of plates to these kind of connections and to analyse the influence of the main parameters governing the bearing resistance: the distance e1 between the hole and the edge of the tube, the distance e2 between the hole and the lateral edge of the plate composing the tube section and the thickness t of the tube.

The in silico prediction of cis-acting elements in a genome is an efficient way to quickly obtain an overview of the biological processes controlled by a trans-acting factor, and connections between regulatory networks. Several regulon prediction web tools are available, designed to identify DNA motifs predicted to be bound by transcription factors using position weight matrix-based algorithms. In this paper we expose and discuss the conflicting objectives of software creators (bioinformaticians) and software users (biologists), who aim for reliable and exhaustive prediction outputs, respectively. Software makers, concerned with providing tools that minimise the number of false positive hits, often impose a stringent threshold score for a sequence to be included in the list of the putative cis-acting sites. This rigidity eventually results in the identification of strongly reliable but largely straightforward sites, i.e. those associated with genes already anticipated to be targeted by the studied transcription factor. Importantly, this biased identification of strongly bound sequences contrasts with the biological reality where, in many circumstances, a weak DNA-protein interaction is required for the appropriate gene's expression. We show here a series of transcriptionally controlled systems involving weakly bound cis-acting elements that could never have been discovered because of the policy of preventing software users from modifying the screening parameters. Proposing only trustworthy prediction outputs thus prevents biologists from fully utilising their knowledge background and deciding to analyse statistically irrelevant hits that could nonetheless be potentially involved in subtle, unexpected, though essential cis-trans relationships.

In 1865 the French mathematician Eugène Catalan was appointed professor at the University of Liege. In the nineteenth century the Belgian government developed a policy of attracting famous foreign scholars, mainly coming from the German principalities and France, in order to bring the education system to a higher level. In this case, however, the appointment had an outspoken political and philosophical dimension. Catalan sought and found refuge in Belgium because his career prospects in France were severely hindered due to his strong republican and anti-Bonapartist viewpoints. In a speech he gave at the University’s Academic Hall on the occasion of his retirement on December 7, 1881, Catalan emphasized he had two passions in life: la Politique militante et les Mathématiques [“Militant Politics and Mathematics”]. In this paper, we investigate the first of these passions against the background of the revolutionary tensions of the time on the basis of a series of primary sources: first, a brochure edited by Catalan himself at the end of his life, entitled Miettes littéraires et politiques, par un vieux mathématicien (Liège, 1889); second, Catalan’s correspondence, covering several decades, and preserved at the Manuscripts Department of the University of Liège; third, a journal kept by Catalan during the years 1858 to 1862, entitled Journal d’un bourgeois de Paris. An in-depth analysis of these sources allows us to discover Catalan’s own perception of his political and philosophical commitments, the reasons behind his involvement in the revolutionary uprisings of 1830, 1848 and 1851, the exact nature of his activism, his interpretation of the republican ideal, his political hopes and deceptions, his view on both French and European social and political realities, his struggle with the Catholic Church, the meaning of his engagement in Freemasonry.

In the context of fulfilling the Water Framework Directive requirements, the LIFE+ project Walphy allowed experimental restoration projects to be undertaken on two medium-size catchments of the Meuse basin in Wallonia (Belgium) between 2009 and 2014. Before undertaking sustainable rehabilitation measures, a multi-scale assessment of hydromorphological conditions (catchment, stream and site) was conducted. It was based on a variety of variables characterizing the river system and its geomorphic processes (e.g. sediment transport), along with human-induced disturbances (e.g. barriers to river continuity). The Bocq catchment has been subject to a large-scale restoration project through the removal or modification of 20 barriers (mainly old weirs), reconnecting the Bocq with the Meuse. In addition, 2.6 km of straightened courses were improved by restoring meanders or diversifying habitats through a wide range of rehabilitation techniques. The success of the restoration projects was evaluated on the basis of a multi-disciplinary monitoring. We compared hydromorphological parameters and biological diversity of benthic invertebrates, fish and macrophytes. 2-3 years post-rehabilitation, hydromorphology was significantly improved. Depending on the rehabilitation measures, the restoration effects observed for invertebrates and fish differ. Weir removal and restored meanders have resulted in the most positive effects, while habitat diversification has led to more contrasted results, depending on the level of ambition. The geomorphological monitoring has focused on the effectiveness of spawning gravel rehabilitation and the effect of barriers on sediment transport. Topographic surveys and the use of pebble tracers have highlighted a natural bedload transport following a weir removal. [less ▲]

Acoustic data were acquired in October 2011 over a Posidonia oceanica meadow in the Bay of la Revellata, Calvi, Corsica. The purpose was to develop an acoustic system for monitoring the oxygen (O2) production of an entire seagrass meadow. In a shallow water area (b38 m), densely covered by P. oceanica, a sound source transmitted signals in 3 different bands (400–800 Hz, 1.5–3.5 kHz and 6.5–8.5 kHz) toward three self-recording hydrophones at a distance of 100 m, over the period of oneweek. The data showa high correlation between the diel cycle of the acoustic signals' energy received by the hydrophones and the temporal changes in water column O2 concentration as measured by optodes. The results thus show that a simple acoustic acquisition system can be used to monitor the O2-based productivity of a seagrass meadow at the ecosystem level with high temporal resolution. The finding of a significant production of O2 as bubbles in seagrass ecosystems suggests that net primary production is underestimated by methods that rely on the mass balance of dissolved O2 measurements.

Les résultats de cette étude montrent qu’en général, les quantités consommées dans les ménages de Kinshasa ainsi que les apports énergétiques et protéiques sont déficitaires et en baisse. Ces quantités et apports sont plus faibles en saison pluvieuse qu’en saison sèche. La situation est alarmante pour les ménages pauvres situés dans la périphérie de la ville. Dans ces ménages, les quantités d’aliments consommées par individu et par jour en saison pluvieuse sont inférieures à 500 g avec des apports énergétiques estimés à 1 130 calories et 50 g de protéines. Il apparait donc que c’est pendant la saison pluvieuse que les ménages, surtout les plus pauvres, déjà en insécurité alimentaire, y tombent davantage. C’est une sorte de période de « vaches maigres » pour ces Kinois. C’est la saison pluvieuse qui est donc la période indiquée et pouvant rendre plus pertinentes les interventions à caractère social ou humanitaire tant du Gouvernement congolais que des autres partenaires. L’analyse qui découle des quantités consommées, des apports énergétiques et protéiques permet de confirmer qu’à Kinshasa, comme dans la quasi-totalité des pays du Tiers-Monde, les modes de consommation sont caractérisés par une forte consommation relative de céréales et/ou de racines et tubercules, complétés parfois par des produits riches en protéines, essentiellement les légumineuses. Il apparait ainsi clairement que les modes de consommation des Kinois s’inspirent des modèles traditionnels ruraux, tant pour les ménages situés dans la partie urbaine de la ville que ceux de la périphérie.
