Interest of end-users and policy makers for understanding and managing water systems at the regional scale has increased for years. At this scale, groundwater models of different complexity ranging from black-box models to physically based distributed models have been used in various hydrogeological conditions. Black-box models, such as transfer functions, have been applied for example to model groundwater in large scale hydrological models, to model karstic systems, in particular for the interpretation of isotopic data. Their concepts are simple and attractive because they require relatively few data. The main drawbacks are however that modelling results are not spatially distributed and their predictive capability is questionable due to the semi-empirical nature of process descriptions. On the contrary, due to a more advanced description of ongoing processes, physically-based distributed models are expected to have better predictive capabilities than black-box models. However, because such models require more data, they are generally applied for case studies that are better characterized from a hydrogeological point of view, for which the distribution of water levels or solute concentrations in the groundwater systems are needed. For large-scale modelling purposes, black-box models and physically-based distributed models have both proved their utilities and have their own justifications, advantages and disadvantages. However, few attempts have been made to combine the advantages of these two categories of approaches in a unified modelling application. A new flexible modelling approach, the Hybrid Finite-Element Mixing-Cell method (HFEMC), has been developed that allows combining in a single model, and in a fully integrated way, different mathematical approaches of various complexities for groundwater modelling in complex and large scale environments. This method has been implemented in the groundwater flow and solute transport numerical code SUFT3D. The approach has been first tested and illustrated using basic and advanced “synthetic” examples that allow validating and discussing its advantages over existing modelling concepts. The HFEMC approach is now applied for the development of a large scale groundwater flow and solute transport model in different groundwater basins in Belgium. [less ▲]

Spatially resolved spectra of the NO delta and gamma ultraviolet bands have been obtained from 80 to 130 km on the Venus night side with the SPICAV instrument on board Venus Express. This NO airglow emission results from radiative recombination of oxygen and nitrogen atoms created on the dayside and transported by the subsolar to antisolar global circulation. Spectral images of the O2 (1 â delta g ) at 1.27 µm have also been made with the VIRTIS-M instrument both at nadir and at the limb. The O2 (1 â g ) emission is produced by three-body recombination of O atoms giving rise to an airglow layer near 96 km. The brightness of both emissions changes by over an order of magnitude. They also show variations in the altitude of the peak emission, with larger variability of the NO airglow. The characteristics of both airglows and their implications on global circulation and vertical transport on the nightside will be discussed. Concurrent observations of both limb airglows will be described. It will be shown that limb observations of the vertical and latitudinal distribution of the 1.27 µm emission make it possible to remotely determine the density of atomic oxygen in the upper mesosphere and improve current atmospheric models. One-dimensional models of the O and N distributions will be presented and global properties of the 1-D parameterization of turbulent transport will be discussed. [less ▲]

This paper describes a rare occurrence of a rich and diverse palynological assemblage from a controversial stratigraphic unit in well EW8 in northwestern Saudi Arabia. The composition of this assemblage strongly suggests a Pridoli age and therefore it is referred here to the Tawil Formation. The assemblage encountered contains very characteristic chitinozoans, acritarchs, tasmanities, scolecodontsm, eurypterid cuticle and common land-derived miospores and hilate cryptospores. Chitinozoans such as Margachitina elegans, Ancyrochitina fragilis brevis, Ancyrochitina fragilis, Sphaerochitina sphaerocephala, Urnochitina urna, Pseudochlathrochitina carmenchui and Lagenochitina brevicollis confer the Pridoli age assignment. This assemblage of chitinozoans correlates very well with Assemblage D from the Alternances Gréso-Argileuses Formation of the A1-61 well in northwestern Libya. Among the acritarchs present are: Cymbosphaeridium pilar, Leoniella carminae,Diexallophasis spp., Tunisphaeridium cf caudatum, Leiofusa estrecha and Eupoikilofusa striatifera. <br /> <br />Furthermore, the join occurrence of U. urna, P. carmenchui and M. elegans is clearly indicative of the middle part of the Pridoli as in the Libyan well A1-61, and in many wells in Algeria. This corresponds to what is considered to be a transgressive mid Pridoli event in the Algerian Sahara, with non marine intervals bracketing this brief marine sea level rise. This event is likely to have extended into all of north Gondwana including Arabia. [less ▲]

This contribution aims to show a multidisciplinary method to understand and formalize design process, from a cognitive point of view, in the particular case of human errors in architectural preliminary design process. We first emphasize the importance of error detection and recovery in the sketching phase in architecture. After the description of our methodology, we explain the general theory and model on human error, the short study we made and our proposition of a model on hu- man error in architectural design. We finally conclude by giving some first re- quirements from this model in order to improve to the development of sketch- based CAD tools. [less ▲]

Clownfishes (i.e. Amphiprion akallopisos) are territorial fishes that use sound production to defend their anemone territory. They live in social groups which display a size-based dominance hierarchy. In such a system, agonistic interactions are frequent and play an important role in the social organization. In addition, these interactions are often associated with sounds. In this study, we compared the sonic features between individuals of different sizes and in different sexual status (juvenile, male and female). The existent relationship between fish size and swimbladder size also implied to seek the swimbladder role in the sound production. Sound analyses showed that juveniles, males and females had distinct sounds in the dominant frequency and pulse duration. These differences were however not in relation to the sexual state; influence of sex on sonic features being mainly the result of a size dimorphism between sexes. Differences in calls were therefore due to the respective size of the emitter. This observation highlighted the role of the swimbladder as a resonance chamber. This role was also reinforced because the experimental filling of the swimbladder with physiological liquid significantly modified the acoustic features. In A. akallopisos, frequency and pulse duration are directly related to swimbladder size, and thus to fish size. This relationship provides strong evidence that the emitter could be identified by its calls. [less ▲]

The goal of this study is the evaluation of the long-term efficiency of voice therapy (> to 6 months) in the treatment of dysfunctional dysphonia . Four subjective measurements were performed on 29 patients: -A visual analogical scale (VAS) ranging from 0 (not efficient at all) to 100 (very efficient). -A question “Is the speech therapy still efficient?” Yes or no. -The G(rade), R(oughness) and B(reathiness) parameters from the GRBAS perceptual scale (evaluated by the patient measured on VAS). -The Voice Handicap Index-10 (VHI-10). The results show that 76% of the patients consider that the voice therapy is still efficient. In regard to G.R.B., we observe a high score for G (median: 77). The score for R is lower (median R: 12). G and R are significantly correlated (r Spearman=0.516, p=0.004), but the satisfaction of the vocal quality does not seem correlated to B (p=0,251, NS). The median values of VHI 10 shows a significant improvement from 15 to 10 (p=0,017). In addition, the correlations between the judgment on the treatment efficiency and vocal quality (r=0,623, p<0,001) and between VHI-10 and the length of treatment (r=0.416, p=0,035) are significant. The first correlation shows that the most satisfied patients when it comes to the vocal therapy are also the most satisfied when it comes to their vocal quality. The second correlation specifies that the longer the treatment, the higher the grade of vocal handicap. Voice therapy is efficient in the long term and is worth to be prolonged for difficult cases [less ▲]
