The main airway function is the conduction of thé air from the amblent air to the gas exchange regions of the lung and conversely. Upper airway include nasal cavities, pharynx, larynx and extrathoracic trachea. These structures, supported by bones, cartilages or muscles, must be as permeable as possible to the air. flow. If for structural or functional reasons, a permanent or dynamic narrowing occurs along the airway, the resulting bottleneck will increase the resistance to airflow, thus impair ventilation and generate abnormal respiratory noises, and finally decrease the exercise capacity. This paper focuses on the function and potential dysfunctions of the different parts of the upper airway in horses [less ▲]

There is currently a debate regarding the status of recall and recognition memory in amnesic patients with focal hippocampal damage. Proportionate deficits of recall and recognition memory have been observed in some patients with selective hippocampal damage. In addition, these patients showed an impairment of both the recollection and familiarity aspects of recognition memory. In contrast, other amnesic patients with selective hippocampal lesions demonstrated relatively preserved recognition memory, despite severely impaired recall abilities. In some of them, familiarity processes were found to be intact. The resolution of this controversy has important implications for theories of episodic memory. In the present study, we examined the recall and recognition performance of an amnesic patient, MR, who suffered from bilateral hippocampal damage and temporoparietal cortical atrophy following carbon monoxide poisoning. Verbal and nonverbal recall and recognition memory were measured by tasks matched for difficulty. On these tasks, MR’s recall performance was more severely impaired than his recognition memory. In addition, MR’s recognition performance was normal on most of the tasks. In order to determine on which processes MR based his recognition decisions, we administered to the patient and to matched controls the process dissociation procedure. This evaluates the contribution of recollection and familiarity within a recognition task. The results indicated that, in this patient, familiarity was preserved, but recollection was impaired. This study thus supports the idea that amnesic patients with hippocampal damage can show preserved familiarity-based recognition memory, despite poor recall and recollection. [less ▲]

For pomerons described by a sum of two simple-pole terms, a soft and a hard pomeron, the unitarity bounds from saturation in impact-parameter space are examined. We consider the effect of these bounds on observables linked with polarisation, such as the analyzing power A(N) in elastic proton-proton scattering, for LHC energies. We obtain the s and t dependence of the Coulomb-nuclear interference at small momentum transfer, and show that the effect of the hard pomeron may be observed at the LHC. [less ▲]

The Ligurian Sea, part of the Cetacean Sanctuary, is known to be a productive area hosting many marine mammal species of the Mediterranean Sea. Investigations on trophic relationship and pollutant monitoring are of primary importance for their conservation. As isotopic composition of an animal is related to that of its prey, ð13C and ð15N were measured by mass spectrometry in muscle of 12 striped dolphins (Stenella coeruleoalba), 1 bottlenose dolphin (Tursiops truncatus), 2 fin whales (Balaenoptera physalus), 3 Risso's dolphins (Grampus griseus), 1 Cuvier's beaked whale (Ziphius cavirostris) and 1 juvenile sperm whale (Physeter macrocephalus) stranded along the Ligurian coasts between 1991 and 2004. Hg concentration was also analysed in marine mammal liver by spectrometric absorption. Through ð13C and ð15N measurements, two marine mammal groups appeared: the first group characterised by high ð13C and ð15N values (mean values: -17.5‰ and 11.0‰ respectively) included the sperm whale, the bottlenose dolphin, the Risso’s dolphin and the beaked whale. The second group including striped dolphin and fin whale displayed lower mean ð13C than the first group (-18,48‰), with the fin whale showing the lowest ð15N value (8,8‰ ± 0,7). Our isotopic data are in good agreement with previously described feeding habits: the first group obviously fed at a higher trophic level and in more coastal waters associated with the continental slope while the second fed offshore, with the fin whale occupying the lowest trophic position. Hg concentrations reflected a similar pattern, with the lowest value observed in the fin whale (mean value: 0.1 µg.g-1 dw) and the highest in both the bottlenose dolphin (3769 µg.g-1 dw) and the Risso’s dolphin (1363 µg.g-1 dw). However, beside trophic position, numerous factors might be involved in Hg accumulation in marine mammals such as the age, body condition and specific metabolism. [less ▲]

We consider random matrix models for the thermodynamic competition between chiral symmetry breaking and diquark condensation in QCD at finite temperature and finite baryon density. The models produce mean field phase diagrams whose topology depends solely on the global symmetries of the theory. We discuss the block structure of the interactions that is imposed by chiral, spin, and color degrees of freedom and comment on the treatment of density and temperature effects. Extension of the coupling parameters to a larger class of theories allows us to investigate the robustness of the phase topology with respect to variations in the dynamics of the interactions. We briefly study the phase structure as a function of coupling parameters and the number of colors. [less ▲]

Most newts experience both terrestrial and aquatic environments during their adult life. A large number of studies explored the feeding habits in the aquatic habitat while very few focused on the terrestrial component and none compared the two systems within a single population. The aim of this study was to find out which foraging tactic is the most successful in terms of energy intake. To this end, I analysed the feeding habits of metamorphosed juveniles in the Alpine newt inhabiting a Greek alpine lake and its surrounding lands. The diet reflected the range of prey available in the two habitats, but invertebrates, which fell on the water surface, were also ingested by aquatic newts. These two lifestyles had different energy outcomes because the highest number of terrestrial invertebrates taken in the terrestrial habitat than in the aquatic one provided higher energy gains to terrestrial juveniles. However, different mortality rates between habitats (highest probability of freezing risk on high-elevated lands than in deep waters) and an expected lower energy intake on land when air temperature is low could explain the persistence of the aquatic foraging tactic in the population.

The study of shoaling behaviours is tackled by scientists by three approaches: the field, laboratory and computer modelling approach. The field studies are complicated and permit rarely an analysis of individual positions. The third approach, consisting of development of mathematic models, is artificial. It requires a comparison with empiric results to validate and to determine the explications’ degree of each model. Thanks to the developments of digital imaging techniques, the laboratory studies on fish are able to measure the behavioural parameters with precision, impossible to realize with manual recording. Multitracking systems are rare and of recent development. These are insufficient to study the real size of shoals, often composed of hundreds of .shes. We have developed a new system of multitracking thanks to collaboration with the G.R.A.S.P. The G.R.A.S.P. has before realised other multitracking systems to follow some hundreds physical objects. Our video multitracking system is able to detect and to track more than a hundred unmarked fishes by gray scaling technique during some minutes. It permits an analysis as well at the group level as at the individual level. The multitraking program is able to attribute a number at each fish and to follow each one during the whole duration of the track. Our system permits the analysis of the movement of each individual, even if the trajectories of two fishes cross each other. It is possible thanks to the theoretical estimation of trajectory of each fish, compared with the real trajectory (analysis with feedback). The human eye is always necessary to detect the errors in identification but reediting is possible. However, if the fishes don’t move too rapidly, a rate of 25 images /s gives very good results, without too much visual expertise from the experimenter. If the fishes are too fast (i.e. escape response), it is better to use a high speed camera. [less ▲]

Carapidae (or pearlfish) are eel-like fishes living inside different invertebrates, such as holothurians, sea stars or bivalves. In some Polynesian areas where they live in sympatry, several species (Carapus homei, Carapus mourlani, Carapus boraborensis and Encheliophis gracilis) are able to inhabit the same host species. The heterospecific infestation rate is very rare, suggesting that the four species can compete for their hosts. Some differences in settlement period, breeding period and in pelagic larval duration (PLD) could allow better characterisation of the life history of each species. More than 700 larvae were collected during an entire year on the Rangiroa atoll (French Polynesia). Each species was identified; their settlement pattern was examined and their PLD was deduced from otolith (sagittae) increments. In the four collected species, the settlement pattern differed: C. homei and C. mourlani settle on the reef during the entire year, and show an asynchronous and diffuse breeding cycle. C. boraborensis and E. gracilis have a shorter settlement period which could be compatible with breeding synchronisation. As most reef fishes, Carapidae larvae mainly settle during moonless nights. Moreover, each species presents some plasticity, allowing it to settle on the reef under suitable conditions. [less ▲]

This paper deals with the consequences of modelling a tapered steel frame with beam elements rather than shell elements. It starts by presenting a specific beam element accounting for the tapering that allows performing geometrically as well as materially non-linear analysis. Then, several kinds of analyses are carried out on two different frames and the results obtained using shell elements, tapered beam elements and prismatic beam elements are compared. This comparison shows that the use of tapered elements leads to results in close agreement with those obtained by shell elements, unlike the prismatic ones. The paper aims at showing that resorting to a so-called segmentation technique should be decided carefully. It also intends at showing the accuracy and convenience of tapered elements when compared to shell models: the total number of degrees of freedom is indeed significantly reduced, leading to easier meshing, shorter computation time and easier interpretation of results.

Coastal ocean circulation models need high-resolution input fields, such as winds, sea surface height and heat fluxes, to represent the variability of coastal systems. Atmosphere model outputs and satellite data are usually used. However, atmosphere models are usually too coarse and do not represent the high variability of coastal systems, and satellite data do not present a complete coverage, mainly due to cloudiness. In situ observations can accurately represent the complex temporal variability of coastal regions, but usually their spatial coverage is far from optimal. Several products derived from atmosphere models, satellite images and in situ observations are prepared to use as high-resolution input fields suitable for coastal models. An optimally interpolated (OI) wind field has been realized by merging atmosphere model winds, satellite-derived winds (from quikSCAT) and in situ buoy measurements. Other fields, such as geostrophic currents, are derived from Sea Surface Height anomaly obtained from the Topex/Poseidon, Jason, ERS 1/2 and Envisat altimeter product of the CLS center, plus a MICOM mean dynamic topography. Sea Surface Temperature (SST) is also needed to correct surface heat fluxes, but satellite SST is often gappy due to clouds. Two different approaches are investigated in order to obtain complete fields, one using OI and the other using Empirical Orthogonal Functions (EOF) for the reconstruction of missing data. The EOF-based method can reconstruct different variables together, such as SST and surface chlorophyll, by using the correlation between them. This multi-variate approach is used here, and compared to the mono-variate OI product. [less ▲]

This research developed at University of Liege aims to optimize the complete semi-continuous casting process at LBP Company, a producer of copper-nickel alloys (or cupro-nickels). The process consists in vertical casting of 7m long ingots. Some problems recurrently occur during casting process: formation of oscillations (wave length of about 500 mm), unsuitable concave cross-sections or internal cracks. In order to reduce the occurrence of such defects and to better understand their formation, we have been asked to develop a finite element model. The research focuses on two main topics: identification of material properties through laboratory tests and literature survey and the development of the numerical tool. The laboratory tests provide thermal and mechanical properties of the ingot and the mould, as well as heat transfer coefficients between the ingot and its surroundings (mould, air and water). These parameters are required for the numerical simulations of the process. In the second part of the research, numerical calculations have been performed using finite element method. Two types of 2D models have already been studied: horizontal slice and vertical slice. This first choice has been guided by the high coupling between thermal and mechanical aspects of the problem, leading to highly complex systems of equations and subsequent long CPU times. However, due to the limitations of such 2D models, a 3D formulation has then been considered and it is still in progress. [less ▲]

The optimal location of a facility is a rather complex task that was already studied many times. Several optimal location problems and solution exists, but only a few can be applied to the location of multimodal freight terminals. Among the possible approaches, if theoretical solutions can be found in the literature, the computational complexity of the proposed methods make them impossible to be applied to real world large geographical networks. Indeed, many of them are based on linear programming, for which the number of constraints drastically increases with the number of terminals to take into account. This paper identifies the possible existing theoretical exact solutions and the framework of a new approach, in which the initial set of potential terminals is computed by means of the results obtained by the assignment of the flows of commodities on the trans-European network [less ▲]

Locomotor activation is often reported to occur after a systemic administration of low doses of ethanol in most mouse strains, as for example outbred CD1 mice. However, in some strains of mice, such as the inbred C57BL/6J mice, and in rats, systemic injections of ethanol typically induce only a depression of the locomotor activity. Recently, Correa et al. (2003) showed that direct infusions of ethanol in the brain ventricles of rats induced locomotor stimulant effects. These authors suggested that some undefined peripheral effects of ethanol may mask its central stimulant effects when ethanol is administered intraperitoneally. The aim of the present study was to investigate the locomotor effects of either intraperitoneal and intracerebroventricular ethanol administrations in two strains of mice, outbred CD1 and inbred C57BL/6J, that are respectively characterized by the presence and absence of a locomotor stimulant response to ethanol. The results showed that ethanol at moderate and high doses induced locomotor depressant effects in C57BL/6J mice whatever the route of ethanol administration. In contrast, ethanol induced a biphasic effect on locomotor activity in CD1 mice with a stimulant response at low doses followed by a significant sedation. Such a response to ethanol was observed after both peripheral and central administrations of ethanol. The results of the present study demonstrate that the locomotor effects of ethanol in mice are not affected by the route of administration, i.e. peripheral or central. In these rodents, there is no evidence that unidentified peripheral effects of ethanol mask the stimulant ethanol effects. [less ▲]

Many CAD tools already allow to create and manipulate directly ideas in a digital way. However, designers still use the pen and paper technique during the early design phase of their projects. Indeed, existing CAD tools con-straint the creative work. There is a need for a sponta-neous human computer interaction in design computing. In order to answer to this need, we develop an integrated aided design tool based on an Virtual Desktop. The de-signer sits in front of a classical desktop where s/he can create and manipulate drawings and generated models. The paper relates the observations made from an ex-periment about the use of the Virtual Desktop by a de-signer. That experiment demonstrates that the immersive aspect of our system interface modifies the relation exist-ing between the designer and his/her model and, this way, its generates a new type of augmented interaction.

The state of Minas Gerais (Brazil) exhibits several major karst areas located in sandstone and quartzite terrains, that display a complex suite of underground and surface karstic forms. In the Espinhaço Ridge, central Minas Gerais, several caves, up to a few hundred metres long, occur in the surroundings of the town of Diamantina. Some of these caves, such as Salitre, represent swallow-holes and show dome pits. Other horizontal caves are characterized by corrosion forms generated into the phreatic zone. In some places, such as in the Rio Preto area, these phreatic forms have been overprinted by ceiling tubes, suggesting a polyphase karst evolution, prior to the draining of the cave. Relicts of passages, with circular cross section up to a metre in diametre, can be found amidst the residual tower-like surface landforms, which constitute a typical scenery in the landscape. Their dissection is due to a generalised karstification in the area, resulting in closed canyons, megakarrens and kamenitzas. In southern Minas Gerais, close to the Mantiqueira Ridge, the caves of the state park of Ibitipoca can extent 2 km in length. These caves are associated with a very large hanging geological syncline. Several of these caves contain active streams, that flow for hundreds of metres before disappearing in sand-choked passages. Keyhole cross sections characterize steeply descending passages in these caves, indicating a change from slow phreatic flow towards a faster vadose flow responsible for the vertical incision of the passage. Such change is probably related to base level lowering and/or to turn in the direction of the water flow. Several generations of wall-pockets, from a few centimetres to over a metre long, occur into the caves. These features are good indicators of the initial phase of speleogenesis, generating the initial conduits by their coalescence. This mechanism is also responsible for cut-off meanders. The main river in the area, which flows along the syncline axis, cuts through a rock barrier, generating a tunnel-like passage. This cave drains, through resurgences in its walls, part of the water that flows in other caves located in the flank of the syncline. The non-carbonate karst features observed in the state of Minas Gerais demonstrate the complex organisation of polyphase karst systems due to the linkage of underground and surface forms not previously connected. As in carbonate areas, these systems may play an important hydrological role. [less ▲]

This study investigated the influence of some physic and chemical parameters of wheat grains on the performances of broilers (Ross). Four varieties (Agami, Corvus, Folio et Meunier) were grown on a single site in harvest year 2003. This cultivar samples are ground and included in starter (57.6 % of wheat) and growth diets (61.4 % of wheat). Broiler’s intake was not influenced (p > 0.05, n = 24) by varieties. But weights of chicken (38 days) were (p < 0.05, n = 516) higher with Folio and Meunier. Feed conversion ratios cumulated between day 3 to day 38 (FCR) were (p < 0.05, n = 24) lower with Folio and Meunier than with Corvus and Agami. Hardness was negatively correlated with FCR (r = - 0.60, p < 0.01, n = 4). The correlation between crude proteins and FCR was equal to - 0.70 (p < 0.001, n = 4). FCR was negatively correlated to Zeleny’s index (r = - 0.62, p < 0.01, n = 4), wet (r = - 0.66, p < 0.001, n = 4) and dry gluten (r = - 0.51, p < 0.05, n = 4). FCR was negatively correlated to ratio of large (> 1800 μm) particles in ground wheat (r = - 0.48, p < 0.05, n = 4) and also related to small (< 707 μm) material (r = 0.53, p < 0.01, n = 4). Surprisingly, FCR was negatively correlated with amounts of soluble Non-Starch Polysaccharides and soluble Arabinoxylans. The same pathway was observed with in vitro viscosity data. Intestinal viscosities were not related (p > 0.05, n = 24) to broiler’s performances. [less ▲]

More than 21 500 harbour seals were killed by Phocine Distempter Virus in the North Sea and adjacent waters in 2002. After the second seal die-off had ceased, seals were captured alive (and then released) on a sandbank (Schleswig-Holstein, Germany) for health and ecotoxicological investigations. Stable carbon and nitrogen ratios (δ13C and δ15N) were measured by mass spectrometry in clotted blood cells of 24 harbour seals captured between 2002 and 2003. Total mercury (Hg) concentrations were determined by spectrometric absorption in the whole blood of 8 harbour seals and compared to the Hg level measured in blood from 8 seals found stranded along the southern North Sea coast. The average isotopic composition measured in the blood cells was –15.6 ± 0.3 0/00 and 18.7 ± 0.6 0/00 for δ13C and δ15N respectively, similar to that obtained previously in muscle of stranded individuals, confirming the high position of the harbour seal in the trophic food chain. δ13C and δ15N values did not differ significantly between seals caught in November 2002, April 2003 and September 2003 suggesting similar diet throughout these 3 periods. The average concentration of mercury in whole blood of living and stranded harbour seals did not differ significantly (94 ± 41 vs 146 ± 71 µg.l-1 respectively). No biological parameters (weight, length, age status and stable isotopes ratios) seemed to influence these concentrations. Blood is known to reflect recent exposure to mercury through the diet. These preliminary results suggest that blood is an interesting substrate for both trophic studies and pollutant long-term monitoring of the harbour seal in the North Sea. [less ▲]

In this paper we study the concept of electric power system control, when the responsibility for controlling the entire system is shared by agents controlling their assigned areas. Within this framework, we suggest to study the dynamics created by the interactions of agents. In particular, we discuss the relation that exists between the information available to the different agents and their optimisation objective, and the performance of the overall power system. Simulations results, carried out on a 39-node power system voltage control problem, are provided and analyzed. They highlight, among others, the sub-optimal performance level attained by the system when the different agents exchange information about their area dynamics without sharing a common control objective.
