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 ▲]

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 ▲]

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 ▲]

High-Frequency Radar Currents are assimilated in a West Florida Shelf (WFS) model based on the Regional Ocean Model System (ROMS) which is nested in the Atlantic Hybrid Coordinate Ocean Model (HYCOM) to include both local and deep-ocean forcing, particularly the Gulf of Mexico Loop Current (LC). An ensemble simulation of the WFS ROMS model is carried out under different wind forcings in order to estimate the error covariance of the model state vector and the covariance between ocean currents and winds. Radial currents measured by HF-Radar antennas near St. Petersburg and Venice, FL, are assimilated using this ensemble-based error covariance. Different assimilation techniques using a time-average ensemble, a filter to reduce surface-gravity waves and an extended state vector including wind stress were tested. Results of WFS ROMS model assimilating surface currents show an improvement of the model currents not only at the surface but also at depth. The LC is a highly unstable current which generates large anticyclones traveling to the West but also a series of smaller anticyclones and filaments moving to the East and affecting the West Florida shelf. An additional tracer is included in the model simulation to track the presence of LC water. With this tracer, the total amount of LC water reaching the shelf and its mechanism is studied. [less ▲]

This paper considers sequential decision making problems under uncertainty, the tradeoff between the expected return and the risk of high loss, and methods that use dynamic programming to find optimal policies. It is argued that using Bellman's Principle determines how risk considerations on the return can be incorporated. The discussion centers around returns generated by Markov Decision Processes and conclusions concern a large class of methods in Reinforcement Learning. [less ▲]

L'estimation de la nuisance olfactive dans l'environnement est une tâche rendue particulièrement difficile par la multiplicité des sources, leur grande variabilité, leur caractère parfois très diffus et fugitif et surtout par la subjectivité de l'appréciation de la gêne. Aussi faut-il mettre en œuvre plusieurs méthodes complémentaires qui vont de l'analyse chimique (GCMS) aux enquêtes de riverains, en passant par l'olfactométrie dynamique impliquant un panel de personnes reniflant différentes dilutions d'un échantillon prélevé sur le terrain. Or, aucune de ces méthodes ne permet un suivi continu des odeurs qui viserait, par exemple, à détecter l'émergence d'une émission particulière dans une ambiance. A ce niveau, la technologie des nez électroniques semble très prometteuse et particulièrement attractive. Basée sur la réponse globale d'un réseau de capteurs non spécifiques, elle permet non seulement d'identifier qualitativement une source particulière, mais également de la suivre en continu. L'unité "Surveillance de l'Environnement" de l'ULg applique cette technique pour suivre les odeurs en périphérie de sites émetteurs et notamment un centre de compostage. Les appareils développés sont basés sur des capteurs commerciaux à oxydes métalliques. La méthode exige une calibration préalable afin de créer et de valider le modèle de reconnaissance et la loi qui relie les signaux des capteurs à une variable quantitative comme la concentration d'odeur. Bien que testée avec succès autour d'installations en vraie grandeur, la technique des "nez électroniques" reste soumise à de nombreuses limitations et contraintes. Parmi ces contraintes, il faut citer la dérive des capteurs, l'influence de l'humidité et de la température, la difficulté de trouver un gaz étalon représentatif des odeurs environnementales ou encore celle de calculer un indicateur global qui serait l'image "électronique" de la nuisance olfactive. En général, la méthode du nez électronique peut être envisagée pour le suivi d'odeurs ponctuelles à la source, par exemple dans un hall de compostage ou dans un bâtiment d'élevage, pour autant que l'ambiance ne soit pas trop agressive. L'unité de recherche teste actuellement le principe de réseaux de nez électroniques placés tout autour d'un site. En ajoutant l'information en provenance d'une station météorologique, un tel système permet la prédiction en temps réel de zones de nuisance olfactive dans l'environnement. Cependant, dès que l'on s'éloigne de l'émission et que l'on s'intéresse à la mesure de l'ambiance olfactive à proximité des habitations des riverains, la technique des nez électroniques présente une limitation sévère due au seuil de détection des capteurs. En effet, le nez humain est parfois sensible à de très faibles concentrations de composés volatils qui ne sont pas détectées par les capteurs. Il devient alors indispensable de piéger ces composés dans des dispositifs de pré-concentration en ligne. De tels dispositifs, actuellement en développement, autoriseraient un élargissement du champ d'application des nez électroniques, notamment vers le domaine très vaste de l'environnement intérieur.

The development of the winter-spring phytoplankton bloom is investigated in the oligotrophic Bay of Calvi (Corsica, Ligurian Sea, Northwestern Mediterranean) since 1979. Time-series results enlighten that changes in environmental conditions in the Corsican sector have altered the coastal phytoplankton dynamics and induced a drastic reduction of the winter-spring phytoplankton biomass over the last three decades. At the local scale, variations in winter wind stress control the development of the winter-spring phytoplankton bloom and the structure of the phytoplankton assemblages. Results emphasize that the total phytoplankton biomass (chl a) is higher during high winter wind stress years. From a specific point of view, flagellates are always the dominant component of the phytoplankton bloom communities. However, diatoms tend to be more abundant during high winter wind stress years. At a wider scale, a link between the intensity of the phytoplankton bloom and the winter NAO index is established. Lastly, the decrease in phytoplankton abundance coincides with changes in zooplankton populations. As a consequence, the entire pelagic food web dynamics is affected by climate variations and the ecosystem resilience is threatened. [less ▲]

In August 2006, Belgium notified its first cases of Bluetongue (BT), serotype 8, in cattle and sheep. The disease was also observed at this time in the neighboring countries. The resurgence of BT was observed in Northern Europe in 2007. The aim of the study was to compare clinical signs of BT observed in 2006 vs 2007 in Belgian cattle. The description of clinical signs was based on the observation of 38 and 39 cows in 2006 and 2007, respectively. BT cases were only included if they were confirmed by one or both laboratory diagnostic tests (competitive ELISA test and/or RT-qPCR). The inventory of clinical signs was made with a standardised clinical form for BT. This form is divided into general, cutaneous, locomotor, digestive, respiratory, neurological and reproductive clinical signs. Case data were summarised to determine changes in clinical presentation of BT between 2006 and 2007. A Fischer’s exact probability test was performed to compare (P<0.05) the frequency of clinical signs between the two years. Regarding general clinical signs, hyperthermia and tiredness were more often observed in 2007, compared to 2006. All clinical signs about skin and annexes were not significantly different between the two years. Locomotor signs such as prostration, incapacity to get up, reluctance to move, lameness and amyotrophy were more frequent in 2007. Loss of appetite, difficulties in grasping feed, salivation and drooling were the digestive signs more often observed in 2007. A purulent nasal discharge was the only respiratory sign more commonly observed in 2007. Apathy, generalised weakness and paresis or paralysis were more often encountered in 2007. The most important changes between the two years concerned reproduction. A higher incidence of abortion, premature calving and stillbirth was observed during 2007 outbreak. The frequency of most of the clinical signs of BT was higher in 2007 in Belgian cattle. Confirmed cases of BT in Belgian cattle were only 296 in 2006 compared to 4187 in 2007. These data do not represent the real situation of BT infection because the farmers do not notify all cases. Nevertheless, it seems that the 2007 outbreak was more severe regarding the number of cases and the frequency of clinical signs. The mild winter and wet 2007 summer might have favored the persistence of the vectors. [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 ▲]

We concentrate particularly on the determination of radiative parameters for selected rare-earth (RE) ions (lanthanides and actinides) and for some atoms and ions of the sixth row of the periodic table.
