Depuis son « âge d'or » dans les années 50, la bande dessinée a été une littérature particulièrement surveillée par les pouvoirs publics. Considérée comme une production destinée à la jeunesse, elle se devait de rester dans les limites de la bienséance. Aux Etats-Unis, cela a donné lieu au début des années 50, à l'instauration du Comic's Code, appliqué par les grands éditeurs. En France, et donc indirectement en Belgique, la loi de 1949 sur les publications destinées à la jeunesse est toujours d'actualité. Quelle a été – quelle est toujours - l'influence réelle de ces règles ? Y'a-t-il d'autres formes de censure en bande dessinée ? C'est notamment de ces questions que traitera la conférence. [less ▲]

La semaine dernière, la presse faisait écho du projet de la SNCB d'introduire des tarifs plus élevés pour les voyages effectués à l'heure de pointe. Concrètement, celui qui prendrait le train dans les tranches 6h-9h et 15h-18h paierait un supplément. La SNCB motive son projet par le fait que le prix actuel est un des plus faible d'Europe. La proposition a –comme on s'en doute- reçu un accueil glacial de la part des usagers du rail. Dans ce focus de Regards économiques, Axel Gautier livre les réflexions d'un économiste (qui est aussi navetteur) à propos de ce projet de la SNCB. [less ▲]

The Lumped parameter method (LPM) is the main method used for space structures thermal design. It is very versatile and allows easy integration of user-defined components but the computation of the conductive links is error-prone and still too often computed by hand. Widely used in structural design, the finite element method (FEM) is however not yet often used for thermal analysis. One of the main reasons is that the radiative exchange factors, usually computed through Monte Carlo ray tracing, are extremely expensive to compute due to the large number of elements composing a FE model. A new global approach for FE model reduction of thermal systems is presented. The method is based on an automated FE mesh partitioning leading to super-faces and super-nodes. It is tailored for radiative exchange factors computation, taking into account selected quadric recognition and material constraints. The method also provides accurate conductive links computation and enables a direct mapping of the reduced temperatures back onto the detailed FE mesh (for e.g. thermo-elastic analyses). The application to two instruments developed at the Centre Spatial de Liège in Belgium will be presented, namely the Extreme Ultraviolet Imager (EUI) onboard Solar Orbiter and the Back Telescope Assembly (BTA) onboard Meteosat Third Generation.

For an incompressible, isothermal, continuous and frictionless flow, the exact resolution of the equation of conservation of mechanical energy is equivalent to the exact resolution of the equation of momentum conservation. However, the discrete solution of the equation of momentum conservation does not verify the equation of energy conservation. This is particularly the case as a result of the presence of a non-conservative bed slope term in the equation of momentum conservation. In this research, the influence of (i) the formulation and (ii) the discretization scheme of the non-conservative bed slope term on the energy conservation is analysed in the case of a 1D horizontal and frictionless channel with a topographic step. The results for two different formulations of the bed slope term are firstly compared: the standard formulation of the bed slope source term and a divergence formulation of the bed slope term. Then, different discretization schemes of the divergence formulation of the bed slope term are analyzed to determine the one minimizing the numerical variation of energy. [less ▲]

Background and aims In experimental settings, 81% of the variance of judges’ rating of pitch accuracy is explained by musical variables (precision of pitch intervals and respect of tonality) (Larrouy-Maestri, Lévêque, Schön, Giovanni, & Morsonne, 2013). In ecological settings, non-musical variables influence judgments of music performances (i.e., McPherson & Thompson, 1998; Platz & Kopiez, 2012). This study aims to better understand the evaluation of pitch accuracy in the context of formative and summative solfeggio examinations at tertiary music level, for which live performances are evaluated. Method Twenty-one participants of conservatory were asked to learn simple melodies during solfeggio classes. They were evaluated two times (formative and summative examinations) by 3 judges. Each performance was also objectively analyzed regarding pitch accuracy (number of contour errors, precision of pitch intervals and respect of the tonal centre) with a computer-assisted method (Larrouy-Maestri & Morsomme, 2014). Results The 3 judges provided strongly and significantly correlated ratings. The musical criteria objectively analyzed explained 56% of the variance of the jury’s rating when the examination purpose was formative (p < .001) and 31% of the variance when the purpose was summative (p = .009). Interestingly, the predictive musical criteria differed depending on the examination’s purpose. In addition, the variance explained by our statistical model increased (from 56% to 67% and from 31% to 46%) when taking into account non-musical variables such as the gender of the music students. Conclusions Besides the educational perspectives, the proposed method appears interesting for examining the influence of non-musical variables on the pitch accuracy assessment in ecological contexts.

Introduction: Osteochondrosis (OC) is a developmental disease in horses which has a significant impact on the horse’s welfare and performance. The early disturbance in the process of endochondral ossification progresses to inflammatory and repair processes in older horses. Previously, differentially expressed genes in leukocytes of OC-affected horses have been identified. The aim of the present study is to detect age-related changes in these differentially expressed genes. Materials and Methods: The expression of OC-related genes was analysed by real-time PCR and subsequent statistical analysis (ΔΔCT) in the leukocytes of 135 Belgian Warmblood horses divided into three different age groups: 30 months (n=38). Results: Relative expression of genes of horses less than 12 months of age showed significant induction of the genes MGAT4A, PRKCG, MHCI, ApoB, ApoB3G, B4GALT6 and a significantly lower expression of the genes OAS3. Horses of 18–24 months of age, showed a significantly higher expression of the genes TBC1D9, MGAT4A, IFIH1, MHCIIa and MMP1. Horses of more than 30 months of age showed a significantly higher expression of the genes MGAT4A, HP, SECTM1 compared with their age-matched control groups. Conclusions: The study demonstrates that OC-related genes are differentially expressed in horses of different ages compared with their age-matched controls. Some of the genes may be implicated in cell signalling and differentiation as well as carbohydrate and lipid metabolism and inflammation. However, the causal relationship between the differentially expressed genes and the development and progression of the OC lesions needs to be determined. [less ▲]

Trends in the vertical distribution of ozone are reported and compared for a number of new and recently revised datasets. The amount of ozone-depleting compounds in the stratosphere (as measured by Equivalent Effective Stratospheric Chlorine – EESC) maximised in the second half of the 1990s. We therefore examine the trends in the periods before and after that peak to see if any change in trend is discernible in the ozone record. Prior to 1998, trends in the upper stratosphere (~ 45 km, 4 hPa) are found to be −5 to −10% per decade at mid-latitudes and closer to −5% per decade in the tropics. No trends are found in the mid-stratosphere (28 km, 30 hPa). Negative trends are seen in the lower stratosphere at mid-latitudes in both hemispheres and in the deep tropics. However it is hard to be categorical about the trends in the lower stratosphere for three reasons: (i) there are fewer measurements, (ii) the data quality is poorer, and (iii) the measurements in the 1990s are perturbed by aerosols from the Mt. Pinatubo eruption in 1991. These findings are similar to those reported previously even though the measurements for the two main satellite instruments (SBUV and SAGE II) and the ground-based Umkehr and ozonesonde stations have been revised. There is no sign of a continued negative trend in the upper stratosphere since 1998: instead there is a hint of an average positive trend of ~ 2% per decade in mid-latitudes and ~ 3% per decade in the tropics. The significance of these upward trends is investigated using different assumptions of the independence of the trend estimates found from different datasets. The averaged upward trends are significant if the trends derived from various datasets are assumed to be independent, but are generally not significant if the trends are not independent. This arises because many of the underlying measurement records are used in more than one merged dataset. At this point it is not possible to say which assumption is best. Including an estimate of the drift of the overall ozone observing system decreases the significance of the trends. The significance will become clearer as (i) more years are added to the observational record, (ii) further improvements are made to the historic ozone record (e.g. through algorithm development), and (iii) the data merging techniques are refined, particularly through a more rigorous treatment of uncertainties.
