Since the creation of the Calvi oceanographic station (STARESO) in the early 1970s, a great deal of data has been acquired by ULg researchers. In 2005 it was decided to create the RACE database in order not only to preserve the old and current measures but also to promote their dissemination and exploitation. In this article, particular attention is paid to the acquisition and exploitation of the meteorological data of the RACE database and also the CalviOnLine database updated every 20 minutes by the on line reception of the new climatological data from a meteorological station located close to the oceanographic station.

Background In the last decades, day surgery has steadily and significantly grown in many countries, yet the increase has been uneven. There are large variations in day-surgery activity between countries, but also within countries between hospitals and surgeons. This paper explores the variability in day-care activity for elective surgical procedures between Belgian hospitals. Materials and methods The administrative hospital data of all patients formally admitted in a Belgian hospital for inpatient or day-surgery care between 2011 and 2013 were analysed and summarized in graphs. During 11 expert meetings with ad-hoc surgical expert groups the variability in day-surgery share between hospitals was discussed in depth. Results The variability in day-care share between Belgian hospitals is considerable. For 37 out of 486 elective surgical procedures, the variability ranged between 0 and 100%. High national day-care rates do not preclude room for improvement for certain hospitals as for the majority of these procedures there are “low performers”. According to the consulted clinical experts, the high variability in day-care share may for the greater part be explained by medical team related factors, customs and traditions, the lack of clinical guidelines, financial factors, organisational factors and patient related factors. Conclusion If a further expansion of day surgery is envisaged in Belgium the factors that contribute to the current variability in day-surgery rates between hospitals should be addressed. In addition, a feedback system in which hospitals and health care providers have the figures on their percentage of procedures carried out in day surgery compared to other hospitals and care providers (benchmarking) and the monitoring of a number of quality indicators (e.g. unplanned readmission, unplanned inpatient stay, emergency department visit) should be installed.

Frequent often-rough contact between players explains why handball has one of the highest injury rates (mainly contusion) recorded at the LondonOlympic Games. Ankle injuries predominated. Head injuries (commotion), shoulder injuries (dislocation and instability), and knee injuries (anteriorcruciate ligament tears) were also common. Wingmen are in constant activity both as attackers and defenders, making them the players with thehighest risk of injury. [less ▲]

Objective Negative symptoms of schizophrenia, in particular motivational deficits, have showed to be linked to dysfunctional attitudes, such as defeatist performance beliefs. This relationship has been found in various types of samples but has not been investigated in samples of individuals presenting persistent negative symptoms (PNS). The present study aimed to assess the relationship between defeatist performance beliefs and negative symptoms in a sample of individuals diagnosed with schizophrenia and PNS. Another objective was to evaluate the link between change in defeatist beliefs and change in negative symptoms, before and after psychosocial intervention. Methods Fifty-one participants diagnosed with schizophrenia and PNS followed 9 months of Motivation and Engagement Training. They were assessed before and after the intervention using the Negative Symptom Assessment (NSA), the Brief Negative Symptom Scale (BNSS), the Clinical Assessment Interview for Negative Symptoms (CAINS), and de the Defeatist Performance Beliefs scale. Results At baseline, defeatist performance beliefs were not significantly associated with negative symptoms, except with the motivation factor of the BNSS, but only at the trend level. However, change in defeatist beliefs was moderately correlated with change in motivation, as measured with the BNSS, but not with the other measures. Conclusion These results underlie the necessity of broadening the targets of psychosocial interventions to factors related to negative symptoms other than dysfunctional attitudes. [less ▲]

Implementing high-level radioactive wastes programs on a territory remain a sensitive step for nuclear waste management organizations. At this stage, the preferred solution of radioactive wastes programs (geological disposal) and their technological developments become highly visible and this is why the new instruments and strategies such as participatory technology development (PDT) have been adopted to tackle the territorial development of geological disposal technology. Considering the coproduction between territory and program (Jasanoff 2004), this presentation focuses on two siting processes of radioactive wastes programs, in France and in Canada to analyze the influence of in(sensible) local participatory technology development strategy and the influence of invited critics (Wynne 2007) on the industrial project. Our results show that frameworks of the participatory technology development have been designed very differently (with or without publics). Consequently, two undesirable, mostly non-intended side effects of information local committees (non) integration have appeared. In France, a closed PDT transformed invited critics as non-invited one. In Canada, a weak engagement of publics has occurred with an opened PDT. In both case, new socio-technical adjustments have occurred in those programs. [less ▲]

The purpose of this paper is to discern in what ways the semiotic methods of the Post- Greimasian French structuralist and the American Peircian traditions can enrich the study of contemporary methods of computational analysis of culture, particularly in the field of Cultural Analytics as implemented by the Russian Art Historian and Computer Scientist Lev Manovich. These semiotic approaches will be helpful in understanding what kinds of visualizations are being generated for use in Cultural Analytics, and what kinds of operations the observer must perform in order to experiment with scientific visualizations of this information.

Proton exchange membrane fuel cell (PEMFC) catalysts are generally made of carbon black (CB)supported platinum-based nanoparticles. However, the properties of CBs, as described by RodríguezReinoso [1], are not optimal for electrocatalysis. A possible solution to the drawbacks of CBs is the use of synthetic nanostructured materials with a controllable and reproducible texture and with a pure, known and constant chemical composition; carbon xerogels (CX) exhibit such properties [2]. Recently, various highly dispersed CX-supported Pt nanoparticles catalysts (Pt/CX) have been synthesized via several methods, such as the strong electrostatic adsorption (SEA) [3] or the charge-enhanced dry impregnation (CEDI) [4]. However, the decrease of the Pt mass contained in the PEMFC electrodes, in particular at the cathode where the oxygen reduction reaction (ORR) is processed, remains a major challenge. Improving the ORR mass activity is currently best achieved by alloying Pt with 3d-transition metal atoms such as cobalt (Co). These alloys perform better than the ORR because the substitution of some Pt atoms by 3d-metal atoms with smaller radius leads to a modified Pt electronic structure [5]. The synthesis and durability of Pt-Co hollow particles/CX (Fig. 1) is currently being studied in our groups. The results indicate that the specific and mass activity of the bimetallic hollow particles dispersed on CX is ca. 10 times higher than that of pure Pt/CB. The first durability results show good stability of the hollow particles structure. Performances and accelerated stress tests (ASTs) in PEMFCs were finally performed. [less ▲]

Underground Pumped Storage Hydropower (UPSH) is an alternative to manage the electricity production in flat regions. UPSH plants consist of two reservoirs of which at least one is underground. For this last reservoir, abandoned mines could be considered. UPSH related activities may induce hydrochemical variations, such as the increase of the oxygen (O2) partial pressure (pO2), which may entail negative consequences in terms of environment and efficiency, especially in coal mined areas where the presence of sulfide minerals is common. This work assesses the main expected environmental impacts that UPSH using abandoned coal mines may induce. [less ▲]

Some hypotheses are still necessary in order to access the ball bearing Newtonian equilibrium with quasi-static methods. Among these hypotheses are the values of the transverse loads within ball/race contacts. Those loads are due to the gyroscopic torques. Nowadays, the transverse loads are estimated without any equilibrium criterion by the specialized literature. Moreover, the race control assumption is often employed in addition to the hypotheses made about the transverse loads. The paper describes a new method to compute the transverse loads without using the race control assumption. Then, a correlation between the ball bearing kinematics and the transverse loads is established. It leads to an accurate and efficient computational method to access the Newtonian equilibrium of high speed ball bearings. [less ▲]

Recent catastrophic events have pointed out the necessity of ensuring the integrity for structures under “exceptional” events. Since many years, the University of Liège is involved in different activities and projects mainly related to the robustness assessment of structures. The robustness of a structure is the capacity of the system to remain globally stable after events not directly ac- counted for in the design, like impact, fire or consequences of a human error, leading to a reason- able damage when compared to the original cause. Particular attention has been dedicated to the loss of column scenario with analytical and numerical investigations. As a contribution to differ- ent European projects (FREEDAM and ROBUSTIMPACT), experimental campaigns have been carried out or are currently undergoing, with the aim of understanding the behaviour of different joint typologies under impact loads. The experimental campaigns have the goal to underline the influence of the strain-rate of the joint components on the behaviour of the tested connections. In the present paper, an overview on the design criteria for the ongoing experimental campaign, on the preliminary results and findings is given and critically analysed. Particularly, an application in the field of the FREEDAM project is presented. [less ▲]
