There is today a real lack of scientific studies and simple design tools to understand wind flows around buildings. This research is based on a great number of CFD (computational fluid dynamics) simulations carried out with FLUENT software to evaluate wind comfort at pedestrian level. This paper describes first the wind comfort criteria chosen. It then develops the process used for validating FLUENT software for wind studies in dense urban environments by comparing our simulations results with wind tunnel tests. This validation shows that wind mean velocities around buildings can be simulated numerically with a very high degree of accuracy. Based on the results of our simulations, we developed simple graphical tools to quantify critical wind speeds around buildings. This article should thus help in practice architects and town planners to design our built environment. Moreover, this paper shows how numerical modelling is now a high-performance tool to work out useful guidelines and simple design tools for urban planners. [less ▲]

Cerebral folate deficiency syndrome, a recently recognized cause of developmental delay, regression, and seizures, is associated with autoantibodies against folate receptors. A female child with developmental delay and a history of seizures who presented with seizures and unexplained coma is reported. Extensive testing to evaluate the patient's coma and subsequent developmental regression were unrevealing until the results of her cerebrospinal fluid neurotransmitter analysis returned. These showed low levels of methyltetrahydrofolate, the active metabolite of folate in the cerebrospinal fluid; subsequently, elevated titers of autoantibodies against folate receptors were found. Despite treatment with folinic acid, she developed intractable epilepsy and severe developmental delay. [less ▲]

Le trouble obsessionnel-compulsif (TOC) est une maladie fréquente et débilitante caractérisée par la présence d'obsessions et/ou de compulsions. Ce trouble entraîne une détresse importante tant pour la personne qui en souffre que pour son entourage. Le diagnostic, avant tout clinique, peut s'appuyer sur différentes échelles d'évaluation. Bien que plusieurs hypothèses étiopathogéniques existent et que différents traitements soient proposés, la physiopathologie de ce trouble reste encore largement incomprise. Le but de cette revue est de synthétiser les dernières avancées en matière de physiopathologie du TOC. [less ▲]

Free surface flows in several shallow rectangular basins have been analyzed experimentally, numerically and theoretically. Different geometries, characterized by different widths and lengths, are considered as well as different hydraulic conditions. First, the results of a series of experimental tests are briefly depicted. They reveal that, under clearly identified hydraulic and geometrical conditions, the flow pattern is found to become nonsymmetric, in spite of the symmetrical inflow conditions, outflow conditions and geometry of the basin. This non-symmetric motion results from the growth of small disturbances actually present in the experimental initial and boundary conditions. Second, numerical simulations are conducted based on a depth-averaged approach and a finite volume scheme. The simulation results reproduce the global pattern of the flow observed experimentally and succeed in predicting the stability or instability of a symmetric flow pattern for all tested configurations. Finally, an analytical study provides mathematical insights into the conditions under which the symmetric flow pattern becomes unstable and clarifies the governing physical processes. [less ▲]

Previous studies that investigated the ability of high priority stimuli to grab attention reported contradictory results. In the present study, eye tracking was used to examine the effect of the presence of the self-face among unfamiliar faces in a visual search task in which face identity was task-irrelevant. We evaluated whether the self-face (i) received prioritized selection, (ii) retained attention, and (iii) whether its status as target or distractor had a differential effect. Another highly familiar face was included to control whether possible effects were specific to the self-face or could be explained by high familiarity. We found that the presence of the self-face affected performance on the search task. This was not due to a prioritized processing but rather to a difficulty to disengage attention. Crucially, this effect seemed due to self-face familiarity. Indeed, similar results were obtained with the other familiar face. Moreover, the effect of the self-face was stronger when it was presented as the target than when it was a distractor. [less ▲]

My paper investigates the meeting of theatre and photography in ‘theatre photography’. Recognizing that both art forms can determine theoretical and philosophical views on representation and self-representation, I aim to compare their visual strategies and the way they construct point of view. In the process several questions are raised: do qualities of photographs belong to objects photographed or to photographs themselves? How important is the object that ‘triggers’ the view? Should the theatre photographer place his camera anywhere? What of framing? In the second section I offer an analysis of photographs taken by Roger Pic in 1957 during the Paris performance of Brecht’s Mother Courage and Her Children by the Berliner Ensemble. This analysis seeks to demonstrate that theatre photography, which often seen as an example of documentary photography, can reach artistic status, provided it relies on enunciative strategies that express what cannot otherwise be photographed in a ‘direct’ manner, namely the characters’ words and emotions.

For the FE simulations relying on elasto-plastic models based on anisotropic yield locus description, it is important for the simulation accuracy to follow a Cartesian reference frame, where the yield locus is expressed. The classical formulations like the Hill 1948 model keep a constant shape of the yield locus when other texture based yield loci regularly update their shape. However in all these cases, the rotation of the Cartesian reference frame must be known. For simple shear tests performed on steel sheets, experimental displacements provide the actual updated position of initial orthogonal grids. The initial and final texture measurements give information on the average crystals rotation. For Hill constitutive law and texture based models, this paper compares the experimental results with different ways to follow the Cartesian reference frame: the co-rotational method, an original method based on the constant symmetric local velocity gradient and the Mandel spin computed by four different methods.

The swimming, air-gaping, and agonistic behaviours of Heterobranchus longifilis (318 +/- 67 mm) were examined while fish were in a fasted state under 12L: 12D and variable group size ( 2, 5, 10 and 15 fish) in a 1000-L aquarium. Fish exhibited a predominantly nocturnal activity pattern independent of group size. A diurnal peak of activity occurred, however, at the usual feeding time. A reduction in frequency of agonistic interactions was observed in larger groups. Five fish were then observed under 72L: 0D and 0L: 72D. The nocturnal activity pattern remained, contrary to the diurnal peak, and was independent of the duration of illumination or darkness. These results suggest the absence of biological clock in H. longifilis, although fish may somehow be influenced by past feeding experience. Behavioural plasticity in this species may provide potential for aquaculture in northern latitudes. [less ▲]
