This article explores the way in which Belgian law deals with situations where labour law engages with the right to freedom of religion and belief and the right not to be discriminated on grounds of religion. It starts with the Belgian regime of religious freedom, protection against discrimination and valid reasons for termination of employment. It then considers specific areas of those regimes in Belgian labour relations, such as the work schedule accommodation, the refusal to perform work, clothing and religious symbols in the workplace, and the work in an ethos organization. It relates mainly to Belgian case law but also to the case law of the European courts. [less ▲]

We introduce the notion of semantic background subtraction, a novel framework for motion detection in video sequences. The key innovation consists to leverage object-level semantics to address the variety of challenging scenarios for background subtraction. Our framework combines the information of a semantic segmentation algorithm, expressed by a probability for each pixel, with the output of any background subtraction algorithm to reduce false positive detections produced by illumination changes, dynamic backgrounds, strong shadows, and ghosts. In addition, it maintains a fully semantic background model to improve the detection of camouflaged foreground objects. Experiments led on the CDNet dataset show that we managed to improve, significantly, almost all background subtraction algorithms of the CDNet leaderboard, and reduce the mean overall error rate of all the 34 algorithms (resp. of the best 5 algorithms) by roughly 50% (resp. 20%). Note that a C++ implementation of the framework is available at http://www.telecom.ulg.ac.be/semantic. [less ▲]

High strength steels (HSS) have specific chemical compositions, which primarily depend on rolling tempering techniques, element thickness and the producer. Nonetheless, EN1993-1-12 related to HSS up to S700 grade does not provide any additional note on the design of steel structures subjected to fire and the designer is referred to EN1993-1-2 valid up to S460 grade. This paper presents the results of a numerical analysis on the behaviour at elevated temperature of Circular Hollow Sections (CHS) columns made of HSS. In details, three full-scale HSS CHS columns with average measured yield strength of 822 MPa and 3.15 m long were tested under the standard ISO fire with constant eccentric compression load. Two members were made of a cross section 323.9 mm x 10 mm and one of a cross section 355.6 mm x 12 mm. The constant applied loads during the tests were respectively equal to 10%, 14% and 19% of the axial capacity of the columns at ambient temperature. Then, a nonlinear thermomechanical finite element model made of solid elements was developed by means of ABAQUS. A fully-coupled analysis using Geometrically and Materially Nonlinear Imperfect Analysis (GMNIA) was employed meaning that the temperature field was determined together with the stress-displacement fields. The calibration of the numerical model was carried out against experimental data by exploiting the thermal and the mechanical properties of steel provided in EN1993-1-2. A sensitivity analysis was performed to highlight the main parameters that affect the simulation results, i.e. mesh size, residual stresses, geometrical imperfections etc. The calibration process showed a good agreement between the numerical results and the experimental outcomes both in terms of failure temperature and of failure mode. With the calibrated model, it was finally possible to perform a preliminary parametric analysis by varying the applied load and the column relative slenderness to assess the appropriateness of the buckling curve included in EN1993 -1-2 to predict the fire resistance of HSS CHS columns.

Robustness of Moment Resistant Frames (MRFs) designed according to current seismic codes and subjected to a loss-of-column scenario is strictly linked to the deformation capacity of beam-to-column connections, which are usually subjected to combined axial and bending loads. In the seismic design of steel frames, once avoided the yielding of columns, a global dissipative collapse mechanism has to be ensured by imposing the formation of plastic hinges at the ends of the beams or in the connections and guarantying, provided that the elements involved in plastic range have an adequate energy dissipation capacity. Within this framework, the aim of this paper is to analyse the influence of the response of the connections designed for seismic application on the global behaviour of MRFs under a loss-of-column scenario providing an accurate modelling of connections subjected to combined axial and bending loads. To this scope four different beam-to-column joints designed for seismic actions, previously tested under cyclic load history at the STRENGTH laboratory of Salerno University, have been modelled and introduced in a case-study structure, whose response has been assessed by means of push-down analyses. The performances of the analysed frames have been analysed and is compared using the Residual Reserve Strength Ratio (RRSR) index combined with the energy balance method. [less ▲]

Recent events such as natural catastrophes or terrorist attacks have highlighted the necessity to ensure the structural integrity of buildings under exceptional events. For more than 10 years, the University of Liege is strongly involved in researches on the response of structures further to such exceptional events through participations to national or European research projects. In particular, the University of Liege has contributed very recently to a European research project entitled ROBUSTIMPACT investigating the behaviour of steel or steel-concrete composite building structures subjected to impact loading and proposing simplified procedures to predict the response of such structures under the considered scenario. As a contribution to this research project, an experimental test campaign was realised in Liège; the objective was to study the behaviour of beam-to-column joints, of column bases and of most of their constitutive components under impact loading and, in particular, to highlight the influence of the strain rate effects on the response of the studied joints and components. The proposed paper first describes the conducted test campaign with all the required details about the tested specimens and the testing setup; then the analysis of the so-obtained experimental results is presented. Finally authors’ views on how to account for the strain rate effects in analytical approaches for joint design is briefly expressed. [less ▲]

On December 2010, several snow events allowed an exceptional snow cover over Belgium. 27 days with snow cover were observed at Uccle and snow depths of 20, 30 and 70 cm were measured on Christmas 2010 respectively at Uccle, Bierset and Mont Rigi in the Hautes-Fagnes. On December 20, while the entire Belgium was covered by a thick blanket of snow, warmer air invaded the country on December 21. This air was quickly replaced by polar air in Lower and Central Belgium (including Bierset). Heavy snowfalls were observed on December 22 and 23, except in the Upper Ardennes where rainfalls occurred under positive temperature which then dropped to -5°C. This event was due to a strong thermal inversion in the lower layers with warm air at 850 hPa above the Ardennes only. This paper aims to explain this atypical extreme event using the regional climate model MAR developed at the University of Liège [less ▲]

Amongst the 1837 papyri from the archive of Zenon, the private secretary to Apollonius, finance minister to Ptolemy II Philadelphus (285-246 BC), about twenty private Greek letters refer to ailments suffered either by the sender or the recipient of the letter, or by a third party. How do these letters, which were not written by medical professionals, designate and describe diseases, their evolution and their outcome? This paper attempts to answer this question, while highlighting the contribution of these documents to the history of health and illness in Ptolemaic Egypt. [less ▲]

Knowledge transmission through a scientific publication is something that can be taught and learned. The CeROArt journal started a project that it has supported and developed over the past ten years to provide educational support to first-time authors who have graduated in conservation, to encourage them to publish their work. This experience, conducted in Open Access with the support of several European training courses, highlights the skills acquired at the end of their studies in terms of scientific communication. It can also be used to consider several avenues for stimulating knowledge pro- duction outside the academic environment. [less ▲]

Contexte : L’EILP-G a été développé afin d’évaluer la sévérité des symptômes affectant la fonction physique et les capacités sportives chez des patients présentant des douleurs de jambe à l’effort. Le questionnaire a déjà été traduit en anglais et en grec. Objectifs : Le but de cette étude est de traduire et de réaliser une adaptation interculturelle du questionnaire EILP-G en français ainsi que d’en évaluer ses propriétés psychométriques. Matériel et Méthode : Le processus de traduction et d’adaptation interculturelle de l’exercise-induced leg pain questionnaire for German-speaking patients (EILP-G) a été guidé par les recommandations internationales d’adaptation interculturelle de questionnaires mesurant l’état de santé. Six étapes ont été respectées : (1) traduction française initiale, (2) synthèse de traduction française, (3) traduction inverse allemande, (4) comité d’expert, (5) test de la version pré-finale, (6) approbation du comité d’expert. 84 sujets furent recrutés et répartis en 3 groupes afin de tester l’EILP-FR : un groupe de sujets pathologiques (n=28), des sportifs à risque de développer ce type de pathologie (n=28) et des étudiants en sciences de la motricité asymptomatiques (n=28). Tous les sujets (n=84) ont rempli le questionnaire français à deux reprises avec un intervalle de 7 à 10 jours, parallèlement au Short Form Health Survey (SF-36) afin de pouvoir évaluer la fiabilité et la validité de l’EILP-FR. Résultats : L’EILP-FR indique une fidélité test-retest très bonne concernant le score total (ICC 0,96). Il en va de même pour le score total de chaque sous-groupe (ICC 0,88-0,94) ainsi que pour chaque item (0,75-0,92). Le questionnaire français présente une cohérence interne élevée (0,93). La corrélation entre l’EILP-FR et le SF-36 est modérée pour le score total (0,51;p<0.001). Une corrélation forte se présente entre le questionnaire et une partie des sous-échelles convergentes du SF-36 (PF, RP et BP ; chaque p<0.001). Les sous-échelles divergentes évaluant les propriétés psychologiques du SF-36 présentent toutes une corrélation faible et statistiquement non-significatives (RE, SF, VT), excepté MH (p<0.05). Aucun effet plancher ou plafond n’a été détecté. Conclusion : La version française, adaptée de la version originale EILP-G, a été traduite et adaptée interculturellement avec succès. L’EILP-FR est un questionnaire fiable et valide pour évaluer les patients francophones souffrant de douleurs chroniques de jambe à l’effort. [less ▲]

Introduction : Le syndrome fémoro-patellaire est l'un des problèmes du genou les plus fréquemment rencontrés. Il se caractérise par une douleur antérieure du genou dans les activités mettant en charge l'articulation fémoro-patellaire. Le Kujala Anterior Knee Pain Scale (Kujala AKPS) est un questionnaire utilisé pour évaluer les symptômes subjectifs, telles que les limitations fonctionnelles et la douleur antérieure du genou. Le questionnaire a déjà été traduit et validé en turc, en portugais brésilien, en persan, en chinois, et en néerlandais. Le but de cette étude est de traduire ce questionnaire en français afin d'en évaluer sa fiabilité et sa validité. Matériel et méthode : La traduction et l’adaptation interculturelle du questionnaire ont été réalisées selon les recommandations internationales comprenant 6 étapes : traduction initiale, synthèse des traductions, traduction de retour vers la langue d’origine, comité d'experts, test de la version pré-finale et approbation du comité d'experts. Une fois la version française obtenue, les participants (n=101) ont rempli 2 fois le Kujula AKPS à un intervalle de 7 jours, et le Short Form Health Survey (SF-36) afin d'en évaluer les propriétés psychométriques (la cohérence interne, la fidélité test-retest et la validité de construit). Résultats : Le Kujula AKPS montre une fidélité test-retest élevée pour le score total (ICC 0,97). La traduction française possède une cohérence interne élevée (0,87). Le Kujula AKPS possède une corrélation forte avec une partie des sous-échelles convergentes du SF-36 (PF, RP et BP). Il y a une corrélation faible ou modérée avec les sous-échelles divergentes du SF-36 (MH, SF et VT). Il n’y a pas d’effet plancher et plafond. Conclusion : La version française du questionnaire Kujula AKPS étant facilement compréhensible, elle semble avoir une bonne adaptation interculturelle. Cette étude a démontré que le Kujula AKPSF est fiable et valide pour les patients francophones souffrant d'un syndrome rotulien. [less ▲]

Some green microalgae synthesize secondary carotenoids as protecting agents under stress. These pigments have high value as feed supplement for aquaculture and as health products. The most promising pigment is astaxanthin, because of its antioxidant, antitumoral and anti-inflamatory properties. The most used natural source of this pigment is the microalga Haematococcus pluvialis. However this species grows slowly and lacks robustness for easy cultivation. Therefore, other species are investigated for astaxanthin production. Here, we identified a locally isolated strain as Coelastrella sp. that is a secondary carotenoid producer. [1] A known typical feature of this genus, that we could observed in the strain by scanning electron microcopy, is the presence of meridional ribs. [2] We analyzed the culture conditions and concluded that this strain grows both autotrophically and heterotrophically and is able of fast change in pigment composition under controlled stress conditions. Thanks to HPLC analyses, we determined that the strain accumulates a variety of secondary carotenoids, among which: astaxanthin, cantaxanthin and echinenone. Unidentified compounds will be further analyzed by mass spectrometry. [less ▲]
