Introduction – Lors de l’enregistrement du potentiel global d’action musculaire (PGAM) au niveau du muscle premier interosseux dorsal de la main (PID) après stimulation du nerf ulnaire au poignet, il est habituel d’observer un pic positif initial (pour une amplification d’environ 1 mV par division). Objectif – Déterminer l’origine de cette déflection positive précédant le PAGM du PID lors de la stimulation du nerf ulnaire au poignet. S’agit-il d’une réponse motrice générée au voisinage de l’électrode de détection active (champ proche) ? La positivité signifiant que les plaques motrices, où est générée cette réponse, ne sont pas exactement sous l’électrode active. S’agit-il, au contraire, de la captation d’une activité générée nettement à distance du système de détection (champ lointain) ? La positivité étant alors liée à l’orientation d’un dipôle électrique par rapport au système de détection. Sujets et méthodes - Dix patients successifs, indemnes d’atteinte du nerf ulnaire, sont étudiés. Une électrode active (G1) est placée sur le PID, au sommet de la saillie musculaire provoquée par le rapprochement actif du pouce et de l’index. L’électrode de référence (G2) est placée successivement sur le pouce, l’index, l’auriculaire, l’os trapèze au poignet et sur le membre controlatéral. Une stimulation électrique percutanée est appliquée au nerf ulnaire au poignet. Le muscle abducteur du Vème doigt (AB5) est également étudié (G1 au milieu de l’éminence hypothénar et G2 sur l’auriculaire). Résultats – Le pic positif précédant le PAGM du PID est en moyenne plus ample lorsque l’électrode de référence est placée sur l’index. Le PAGM du PID débute systématiquement par une déflection négative lorsque l’électrode de référence est placée sur l’os trapèze au poignet ou sur le membre controlatéral. L’absence de positivité initiale est associée à un raccourcissement de la latence distale motrice. Lorsque le gain des réponses motrices du PID et de l’AB5 est fixé à 0,1 ou 0,2 mV/division, quel que soit le muscle étudié et quel que soit le montage G1/G2 utilisé, toutes les déflections initiales (positives ou négatives) présentent une latence identique ou presque. Discussion – La déflection positive initiale qui précède le PAGM du PID, lorsque G2 est distale par rapport à la cathode, reflète l’activité générée au niveau des autres muscles innervés par le nerf ulnaire et notamment l’AB5. L’absence de cette positivité, lorsque G2 est proximale à la cathode ou sur le membre controlatéral, est liée à une inversion de polarité de la déflection initiale. Il en résulte, une réduction artificielle de la latence distale motrice. Ce type de référence doit donc être évité dans nos examens de routine. Conclusion – Ce travail souligne d’une part, l’importance de G2 dans l’enregistrement d’un PAGM et d’autre part, que les enregistrements de surface peuvent être influencés par la contraction de muscles situés à distance du couple G1/G2, même si un seul nerf est activé par la stimulation électrique percutanée.

La sensibilité à l'anxiété (AS)est la peur des sensations corporelles liées à l'anxiété. Plusieurs études constatent qu'une grande proportion de la variance de l'AS des filles et la totalité de la variance de l'AS des garçons s'expliquent par des facteurs environnementaux. L'objectif est de dégager, chez l'enfant au sein du milieu familial, les facteurs de risque et de protection de la sensibilité à l'anxiété (AS). Dans un premier temps, le lien entre divers états émotionnels des parents et la présence d'une AS chez leur enfant sera étudiée. La part contributive des mécanismes d'apprentissage (transmission d'information, renforcement, modeling) de l'AS lorsque l'enfant ressent des symptômes corporels sera également analysée. Différents effets seront testés: le type d esymptômes sur lequel l'apprentissage porte (douleur/anxiété), la source (père/mère) et la diversité des apprentissages. Dans un second temps, afin d'affiner les liens entre les états émotionnels des parents, les expériences d'apprentissage au sein du milieu familial et la présence d'une sensibilité à l'anxiété chez l'enfant, l'influence de deux modérateurs sera testée: l‘intelligence émotionnelle de l'enfant et les apprentissages sociaux. Les hommes apprennent qu'il est moins acceptable pour eux que pour les femmes d'exprimer leurs craintes. Les mères parlent plus volontiers de leurs inquiétudes et donc, lorsqu'elles présentent des manifestations anxieuses, elles peuvent plus facilement expliquer à l'enfant que ses peurs sont irrationnelles contrairement aux pères qui préféreront ne pas en parler. Que se passerait-il si le père parlait de ses craintes sachant qu'un père qui oserait exprimer sa détresse sera perçu de façon plus marquante par son enfant qu'une mère qui ose le faire? [less ▲]

According to us, it matters to situate the sustainable development in relation to the social responsibility and to the question of the different actors. It is in this particular context that we will analyse the relationship between the trade unions and the sustainable development in Belgium. We will show the involvement of the trade unions in relation to the three areas which define the sustainable development: the environment protection, the work quality and its organization and the benefit notion. This implication depends on the relations between the actors: state, company, workers (notably the trade unions). The question of sustainable development is culturally rooted and is linked to a certain conception of the economy and of the social contract. Obstacles are liable to appear during the appropriation of the sustainable development by the trade unions. The resolution of these difficulties is linked with the company management, the corporate culture and the type of negotiation. The trade union involvement depends on particular situations and specific contexts. We will therefore show that a systemic and contingent approach to the problem is required. [less ▲]

In Parkinson's disease, altered activity in posterior associative cortices has often been associated with dementia. It remains to be determined if this pattern is a reliable marker of a progression toward dementia in patients without demonstratable dementia. In this retrospective analysis, we used positron emission tomography to study resting-state cerebral fluodeoxyglucose uptake in 8 healthy controls and 8 Parkinson's disease patients who did not have evidence of dementia at the time of assessment. For those patients, clinical follow up was available and we know that they did not meet dementia criteria on average 10,37 years after assessment. The results show that patients had reduced fluodeoxyglucose uptake mostly localised in the right hemisphere and including precuneus, superior temporal, middle temporal and inferior parietal cortices. It also includes right insula. These cerebral activity predominating in posterior cortices is present in non-demened patients but is not always predictive of dementia within the 10,34 years.

Les caractéristiques du langage adressé à l’enfant ont un impact important sur l’acquisition langagière, tant chez les enfants présentant un développement normal du langage que pour ceux qui ont des troubles langagiers. Mais, pour ces derniers, le bénéfice lié à un input optimal est plus important que chez les enfants sans trouble (Snow, 1994). Malheureusement, en raison même du retard de développement du langage, l’ajustement du langage de l’adulte à l’enfant est rendu plus difficile (D’Ordorico & Jacob, 2006). On se trouve dans une spirale négative : les enfants fragiles au niveau langagier dépendent plus que leurs pairs de la qualité de l’input qui leur est proposé et, à cause de leurs difficultés langagières, ils suscitent des interactions moins riches et moins à même de les soutenir dans leur développement langagier ultérieur. Face à ce constat, des programmes d’intervention ont été mis en place (Girolametto, Weitzman, & Greenberg, 2004). Dans ce travail, nous présenterons les résultats obtenus suite à une session de guidance parentale organisée avec les parents de 4 enfants d’environ 4 ans présentant un retard de développement de langage. L’objectif de cette formation est d’aider les parents à tenir un rôle d’acteur principal dans le développement langagier de leur enfant, en lui donnant des occasions de communiquer, en suivant ses intérêts, en le plaçant dans des routines prévisibles et familières, et en lui fournissant un langage plus adapté à ses difficultés. Dans un premier temps, chaque enfant a été filmé en interaction avec ses parents afin de disposer de mesures pré-thérapeutiques concernant le niveau langagier et communicatif de l’enfant et les stratégies d’interaction parentales. Ensuite, deux orthophonistes ont travaillé avec le groupe de parents afin de les familiariser aux stratégies utilisées dans les programmes d’intervention parentale. Ces stratégies sont les suivantes (Girolametto, 2004) : 1) les stratégies centrées sur l’enfant (par exemple, se mettre au niveau de l’enfant, attendre que l’enfant initie l'interaction) ; 2) les stratégies de promotion de l’interaction (par exemple, encourager l’enfant à prendre leur tour dans une interaction, à poser des questions) ; 3) les stratégies de modelage du langage (par exemple, l’expansion, la reformulation, etc). Enfin, deux séances de post-thérapie ont été réalisées, la première directement après la session de formation, la seconde 6 mois plus tard. Chaque film a été transcrit et analysé. Les résultats, qui seront présentés et discutés, ont des implications importantes en termes de prise en charge précoce des enfants présentant des troubles de développement langagier. [less ▲]

Towards the end of the 20th century, as the propagation of new discourses of ethnic success generated new versions of the American Dream, “America” came to signify not only immigrant mobility and whiteness, but also multiculturalism. As Inderpal Grewal argues in Transnational America, this paradox of sorts was only made possible through a slippage in the meaning of “white,” within which whiteness still connoted Anglo-America, yet extended its meaning to include a more heterogeneous group that passed as white through the endorsement of culturally-specific consumerist practices and middle-class norms of behaviour. Posing as multicultural yet covertly fastening whiteness to an ideal Americanness, these so-called “new” versions of the American Dream elevated the Asian American community to “model minority” status, thus contributing to rationalize away the lure that a “relative whiteness” could somehow be acquired by non-white minority groups. Drawing on whiteness studies and psychoanalytical theory, my paper will explore representations of interracial relationships as a means to claim and/or contest the ideal of whiteness in Mohsin Hamid’s The Reluctant Fundamentalist. In Hamid’s novel, the 9/11 attacks trigger a crisis in self-identification for model-minority protagonist Changez, which proves illuminating in terms of the invisible racial subjugation exerted so far onto him by Jim, Changez’s passport into the corporate world, and by Erica, his (white) lifeline to exclusive Manhattan. My paper will focus on the ways in which Hamid uses the post 9/11 context to reveal the racial melancholia surreptitiously informing today’s “new” versions of the American Dream, which is apparent in Changez’s and Erica’s relationship as well as in their parallel impossible mourning of the broken mirror of “white” Am/Erica. Emphasizing the extent to which whiteness and racial melancholia permeate the discourse of assimilation, Hamid’s book rewrites the “new” American Dream as a “fantasy built on absences” (Anne Anlin Cheng).

Notre recherche a pour but de mieux repérer ce qui semble faciliter chez l'enfant tout venant son développement linguistique et communicationnel, afin de mettre en place des stratégies éducatives adaptées aux enfants présentant des troubles du langage. Dans une étude longitudinale des interactions mère-enfant chez trois enfants tout-venant entre 1 an 6 mois et 3 ans, notre équipe s'est penchée sur un phénomène interactionnel au croisement de l'appropriation du système linguistique et de son usage : les rectifications. Nos analyses soulignent le rôle clé de la mère ainsi que les similarités et les différences entre les dyades.

Nowadays, collision avoidance (CA) systems are an intensive research topic since the majority of all traffic accidents are collisions that are caused due to inattention or unadjusted driving behaviour of the driver. Up to date prototypic CA systems are based on on-board environmental sensors, such as camera or radar systems, in order to scan the vehicle’s surrounding for potential crashes. The functionality of the used sensors under varying environmental conditions and the limited sensor covering area require an enormous effort to ensure a reliable detection of obstacles, and thus limit the application of the systems. In order to expand the operating field of such systems, a GALILEO-based CA system will be developed within the project GALILEO-above. This advanced driver assistance system detects surrounding vehicles that are on collision course, and react autonomous, if the driver does not intervene to avoid the crash. For this purpose the system initiates an emergency stop or an emergency steering. For the development of the CA system the GALILEO test centre “Automotive Gate” in Aldenhoven, Germany will be used. On this test area pseudolites will be installed which provide GALILEO-like navigation signals. Thus, the development respectively tuning of GALILEO based vehicle systems will be enabled, so that they are available on the market when the GALILEO satellite system becomes operative. At the end of the project GALILEO-above, first prototypes should demonstrate the potential of GALILEO-based collision avoidance systems. In this paper the GALILEO-above project will be introduced followed by a detailed description of the development process of the CA system. Furthermore, first results will be presented. [less ▲]

Pharyngo Laryngeal Reflux (PLR) influences the voice quality : hoarseness, vocal fatigue and hypertonia (Shaw et al, Hopkins et al). Our goal is to measure the influence of the PLR on the voice of 96 subjects by using the Belafsky’s reflux symptom index (RSI) and reflux finding score (RFS). 46 dysphonic patients (26M/24F) constitute the experimental group (EG) and 50 subjects (13 M/33F) without vocal or gastric complaint the control group (CG). All are evaluated by subjective measures (RSI), D-type scale (DS-16, Denollet et al) and objective measures (Video Laryngo Stroboscopy, RFS). The EG shows a RSI score significantly higher on test than on the retest (p=0.002). The specificity of the RSI calculated on the CG amounts to 98 % (chi ²: p < 0,05, Cramer: 0,678). The EG scores are significantly higher than those of the CG (p=0,000) although the CG obtains scores significantly higher as for the eating risk habits (p=0,001). In the EG, we note a correlation between the coffee consumption, the item 9 (pyrosis) (rho: 0,32; p < 0,05 ) and the global RSI score (rho: 0,35; p < 0,05). In the CG, alcohol consumption influences significantly the item 9 (rho: 0,47). The correlations between RSI and RFS are not significant (p < 0.05). The ENT evaluation is severe and probably influences the result. We observe no influence of the gender and of the D-type scale on the RSI scores (p <0.05). The RSI scale is an interesting tool for the detection of RPL. [less ▲]

The term empathy refers to two related human abilities: mental perspective taking (cognitive empathy) and the vicarious sharing of emotions (emotional empathy). The main object of this study was to explore the relationship between capacities of both aspects of empathy and their relationships with interpersonal difficulties in alcohol-dependant patients (AD). The research in alcoholism empathy has focalised around one aspect of cognitive empathy - the capacity to infer an emotional state-, and that essentially on the basis of emotional facial expression (EFE) recognition. However, researchers have shown little interest in the investigation of the other aspects of cognitive empathy. The present study focuses on the capacity to infer interpersonal intentions and on emotional empathy. As documented by the research on EFE decoding, AD patients show deficits in cognitive empathy. In this study, we investigated their capacity to infer interpersonal intentions in social situation. We hypothesized that AD patients compared to healthy individuals and to depressed patients will attributed more intentions of reject and of aggressiveness to other people on the basis of their EFE. In this study, emotional empathy was defined as the modulation of the emotional feeling state of the participant in function of the EFE display by other people. We hypothesized that the modulation in AD patient will be different from the one of healthy people in function of the Cloninger subtype of alcoholism (Cloninger, Bohman, Sigvardsson, 1987). This emotional reactivity will be more important in Type II alcoholism and less important in Type I alcoholism. As Mimicry facilitates feelings of empathy in healthy people, it was also investigated. Twenty type I AD patients, 20 type II AD patients, 20 depressed patients, and 20 healthy subjects participated to the study. The alcoholism subtype identification was maid according to the criteria from von Knorring, Bohman, von Knorring, and Oreland (1985). The participant completed questionnaires assessing the quality of interpersonal relationships, their usual quantity of alcohol consumption, and, for AD patients, their level of alcohol dependence. Their capacity to recognise faces was evaluated by the Benton facial recognition test. The empathy tasks were computerized. In the cognitive empathy task, the participants had to evaluate the adequacy (in a 7-point Likert scale) between a film of a face changing from a neutral EFE to an emotional EFE (the photographs come from the material of Matsumoto & Ekman, 1988) and an adjective descriptive of personality. Each adjective was weighted on the interpersonal dimensions of reject, aggressiveness, dominance, and affiliation. In the emotional empathy task, the participants had to evaluate their own emotional feeling state (in a 7-point Likert scale; from very negative to very positive) after watching a series of films depicting emotional faces (same material as before). During this task, the participant’s face was filmed in order to assess mimicry. The differences of empathy capacities between AD patients and control participants (depressed and healthy) are discussed in reference to the characteristics of their interpersonal relationship.

Computation of lactation yields from test-day data has lost much of its importance for genetic evaluations as the use of test-day models is currently quite widespread. In the other hand its interest for intra-farm management is increasing as a base for advanced management tools. The first and principal aim of this study was to develop a method which takes into account advantages and disadvantages of existing methods, and to test its potential to provide useful management tools to dairy farmers. A test-day model with modifications to able daily run and management tools was developed. Because of its similarities with best prediction, the method developed here was called modified best prediction. The second objective was to compare the accuracy of this new method with best prediction and test interval methods. Modified best prediction showed good results for predicting daily yields and was slightly better than best prediction for lactation yields prediction. Management tools obtained with modified best prediction are explained. [less ▲]

Socially anxious children have difficulties to interact adequately with others. The core characteristic of social anxiety, the fear of being negatively evaluated by others, may among others, be based on problems with the decoding of other persons’ emotional facial expression (EFE). Up to now, the research on EFE recognition in socially anxious children has produced mixed results. Whereas some studies reported differences between anxious and healthy children in EFE recognition (e.g., Simonian, Beidel, Turner, Berkes, & Long, 2001), others didn’t find such differences (Melfsen & Florin, 2002). In this study, we addressed two new issues in the investigation of EFE recognition in socially anxious children. Firstly, we investigated self-esteem. Socially anxious children show low confidence in one’s cognitive and social abilities. Furthermore, high self-esteem is related to high capacities of EFE recognition (Garfield, Rogoff, & Steinberg, 1987), and more generally to high level of social functioning (Serretti et al., 1999 ; Shapira et al., 1999). Indeed, the perception of ourselves depends on the way we think others people perceive us. Secondly, past researches have investigated this issue in low anxious situations and thus, not in situations in which social anxious individuals feel threatened. The originality of the present study is that it addresses the relationship between EFE recognition performance and self-esteem in children placed in an anxious social situation. We predicted a low capacity to decode EFE in socially anxious children. Moreover, we hypothesised a relationship between a low self-esteem and difficulties to decode accurately EFE in an anxious social situation. Seventy children (8 – 12 years) were placed in an anxious social situation of performance in which they were instructed to count aloud backwards, beginning at 200 in increments of 13. Children assessed their emotional feeling state, including their degree of anxiety, before and after the anxious social situation. Furthermore, children were assessed on an EFE decoding test consisting of 16 photographs depicting EFE of happiness, anger, disgust, and sadness. For each photograph, they evaluated the presence of nine types of emotions on a 7-point Likert scale. They also completed the Self-Perception Profile for Children (Harter, 1985). No correlations emerged between the accuracy of EFE recognition and an increase of anxious feelings after the anxious social situation. However, self-esteem was correlated with performance on the EFE recognition test, r (70) = -.33, p < .01. Moreover, the lower the child’s level of self-esteem was, the more he/she perceived negative emotions (fear, anger, disgust, and shame) in EFE of anger. In conclusion, social anxiety doesn’t seem to interfere with EFE recognition performance in an anxious social situation. However, low level of self-esteem in children appears to be associated with deficits and interpretative bias in EFE recognition in an anxious social situation. The recognition of the expression of anger, an emotion socially threatening, seems particularly biased in children with low level of self-esteem. [less ▲]

The question of lowering the voting age to 16 has long been debated in university circles. In the last Austrian elections, young people aged 16 and older were invited to vote, even if young people themselves are divided over this issue, even hostile to the idea. Nevertheless, isn’t such a question, which is rarely discussed by the larger public and touches on several dimensions of a person’s life, an ideal topic for a debate, where the confrontation of ideas may change opinions and reveal – or even modify – young people’s global attitudes towards political interest and participation? A non-random sample of nearly two hundred 16- to 22-year-old youth in French-speaking Belgium was selected to discuss the possibility of lowering the voting age to 16, as well as political interest and political participation, during one day with four experts. The same questionnaire was filled in in the beginning and at the end of the day. These first results are presented here. They show little evolution during the discussion, in a sample already largely against the idea of lowering the voting age. However, these are the consequences for political socialisation we would like to discuss with this research project based on political reasoning. [less ▲]

Nowadays, collision avoidance (CA) systems are an intensive research topic since the majority of all traffic accidents are collisions that are caused due to inattention or unadjusted driving behaviour of the driver. In order to scan the vehicle's surrounding for potential crashes, up to date prototypic CA systems are based on on-board environmental sensors, such as camera or radar systems. The limited sensor covering area and the functionality of the used sensors under varying environmental conditions require an enormous effort to ensure a reliable detection of obstacles, and thus limit the application of the systems. In order to expand the operating field of such systems, a Galileo-based CA system will be developed within the project "GALILEO above". This advanced driver assistance system detects surrounding vehicles that are on collision course, and react autonomous, if the driver does not intervene to avoid the crash. For this purpose the system initiates an emergency stop or an emergency steering. For the development process of the CA system the Galileo test centre "automotiveGATE" in Aldenhoven, Germany will be used. Pseudolites will be installed at the automotiveGATE which provide Galileo-like navigation signals and enable the development and tuning of Galileo based vehicle systems. Thus, these systems are available on the market when the Galileo satellite system becomes operative. At the end of the project GALILEO above, first prototypes should demonstrate the potential of Galileo-based collision avoidance systems. In this paper the GALILEO above project will be introduced followed by a detailed description of the development process of the CA system. Furthermore, first results will be presented. [less ▲]

The two-Higgs-doublet model (2HDM) realizes ground states (vacuum) with different properties for different parameter values. The parameters of the effective potential change during cooling of the Universe after the Big Bang. In so doing, the properties of vacuum state can be affected, phase transitions take place. The evolution of phase states and the set of phase transitions can turn out to be much wider than those accounted for within the conventional Standard model (SM) with a single Higgs doublet. The phase history of the Universe is analyzed for any specified set of the 2HDM parameters. All possible variants of the history are considered. Sets of modern, observed, in principle, parameters corresponding to different sequences of thermal phase transitions are determined. Possible cosmological consequences are briefly discussed.

Objective: The present study investigated the Autobiographical Memory (AM) in borderline disorder population. AM is an entity that encompasses the individuals’past personnal experiences. Previous researches have shown disturbances in AM among several psychiatric disorders such as depression, schizophrenia and bipolar disorder. This disturbances take the overgeneral retrieving form. Thus, when patients were asked to retrieve a specific event located in time and place, they recalled an overgeneral event. This deficit is not an isolated phenomen. Indeed the researches showed that AM deficits is related to decreasing of the ability to solve interpersonnal problem (Evans et al., 1992; Goddard et al., 1996) and impairments to project onself into the specific future events (D’argembeau et al., 2008; Williams et al., 1996). Impairments to respond adequately to social problems or to concrete plans for the future create hopelessness and to contribute to suicide attempt (Arie et al., 2008). Given the high risk of suicide or suicide attempts present in the Bordeline Personnality Disorder (BPD), consideration of AM in this population is appropriate. The aim of the present study was investigate the AM, the projection into the future and the problem solving in patients suffering from BPD. Method: 21 subjects BPD and 21 healthy controls participated in this study. First, the participants were asked to complete TeMA (validated French versions of AMT by Neumann & Philippot, 2006). Participants were instructed to generate specific past and future memories in response to cues words. Secondly, they were had to complete the OTT, they were asked to yield the most solutions as possible to daily problems. Finally the depression was controlled as well as neuropsychological variables. Results: The subjects with BPD recalled less specific past events and imagined less specific future events than healthy subjects (t(40) = 2.21, p = .031; t(40) = 3.4, p = .001, respectively). In addition, the number of past and future specific events was marginally correlated (r(42) = .31, p = .051). However, no difference between two groups on OTT and no correlation between past specificity and problem solving emerged. Discussion: As other clinical populations, the subjects with a BPD encounter deficits to retrieve specific past events. Moreover, these impairments are associated with deficits to imagine specific future events. Nevertheless, the ability to generate specific events was not related to the ability to solve problem. The observation of reduced specificity in the generation of autobiographical material is particularly clinically relevant. Indeed, difficulty in imagining the future may contribute to relapse. In conclusion, more systematic measure of this ability should be taken in both research and clinical fields. [less ▲]

This paper aims to evaluate Senegalese consumers' willingness-to-pay (WTP) for local fresh milk-based products, in opposition to the ones produced with imported powder. Exploiting data from a choice-based-conjoint analysis conducted on 400 households in the region of Dakar, we evaluate the premium that consumers are willing to pay for fresh raw material (rather than powder) in the composition of sour milk. Based on an Ordered Probit Model, the results show evidence for a positive WTP for fresh raw material, which may be seen as a strong indication of preference for local products. This WTP greatly depends on the characteristics of the households. Wealthier households are willing to pay more than the medium households, while big households are ready to pay much less than the base category ones. Obviously, some niche markets exist, that producers may target to sell the local milk-based dairy products. However, more information has to be provided about the composition of dairy products, as consumers are not currently able to distinguish both types of raw material, even if they are willing to pay more for one of them. In spite of some restrictions about the presence of a potential "hypothetical bias" due to the nature of the data, this study gives a first insight of consumers' preferences for local milk-based dairy products.

Milk coagulation has a direct effect on cheese yield. Several factors influence the milk coagulation kinetics. In addition to calcium and milk protein concentrations, titratable acidity influences all the phases of milk coagulation. The objective of this research was to study the feasibility of prediction of titratable acidity directly in bovine milk using mid-infrared spectrometry. In order to maximize the variability in the measurements of titratable acidity, milk samples were collected on basis of several criteria (e.g. breeds). The titratable acidity was recorded as Dornic degree. All samples were also analyzed by MIR spectrometry. Using partial least squares regressions and first derivative pretreatment of spectral data, a calibration equation was built to predict the Dornic degree in cow milk. First results were promising and showed the potentiality to this calibration. The calibration and cross-validation coefficients of determination were 92.25 and 89.88 %, respectively. Moreover, the ratio of standard error of prediction to standard deviation was 3.13 and permits us to consider the calibration equation as usable in most application such as scientific researches and the screening of the Walloon dairy herd particularly in order to improve the milk coagulation properties.

This paper presents the new report n°106 of PIANC InCom WG29 on Innovations in Navigation Lock Design, published by PIANC in August 2009, as well as some additional contributions on lock gates (gate contact technology). The paper highlights the main objectives and issues of his PIANC report with a specific emphasis on gates and specifically on the contact aspects. Locks are key structures for the development of the navigation in canals and in natural rivers where weirs regulate water levels to enable navigation. They may also be strategic infrastructure for port development. The core of this report has three major parts. The first part presents an exhaustive list of design goals associated with locks. This section is particularly important for decision makers who have to launch a new project. The second part reviews the design principles that must be considered by designers. This section is methodologically oriented. The third part is technically oriented. All main technical aspects (hydraulics, structures, foundations, including computational aspects, etc.) are reviewed, focussing on changes and innovations occurring since 1986. Perspectives and trends for the future are also listed. When appropriate, recommendations are listed. It is impossible to give the details of all lock innovation areas in this paper. As an example, the lock gates and, in particular, the modern views on their contact issues have been chosen. These new solutions are welcome to limit the maintenance and to extend the service life of lock gates. [less ▲]

A contaminated alluvial aquifer, in a former gasworks factory, discharging to an adjacent river was the object of field and laboratory investigations to assess pollutant attenuation and dispersion. Various organic and inorganic compounds were found in the aquifer in concentrations exceeding regulatory values, among them, benzene, which was presenting the major worry for off-site dispersion, mainly due to its mobility and high concentration, i.e. up to 750 mg L-1 in the source zone. However, benzene could never be detected near the river which is about 160 m downgradient the main source. Due to redox conditions of the aquifer, heavy metals were almost immobile, thus not posing a major risk of dispersion off-site the brownfield. Benzene concentrations together with redox conditions in the aquifer, suggested that benzene degradation was mainly occurring within 100 m distance from the contaminant source under anoxic conditions, and most probably with sulphate as main oxidant. A numerical groundwater flow and transport model, calibrated under transient conditions, was used to simulate benzene attenuation in the alluvial aquifer towards the Meuse River. The mean benzene degradation rate used in the model was quantified in situ along the groundwater flow path using compound-specific carbon isotope analysis (CSIA). The results of the solute transport simulations confirmed that benzene concentrations decreased almost five orders of magnitude 70 m downgradient the source. Simulated benzene concentrations were found to be below the detection limit in the zone adjacent to the river and consistent with the absence of benzene in downgradient piezometers located close to the river. In a transient model scenario including groundwater-surface water dynamics, benzene concentrations were observed to be inversely correlated to the river water levels, leading to the hypothesis that benzene dispersion is mainly controlled by natural attenuation and river fluctuations.

Objective: In the recovery from coma, the acquisition of command following represents an important milestone, indicating emergence from the vegetative state (Schnakers et al., 2009). In some patients, recovery of consciousness may precede motor recovery. Brain-computer interfaces (BCI) might permit these patients to show non-motor dependent signs of awareness and in a next step might enable communication. This study aimed at testing to what extent an EEG-based BCI could help detecting signs of awareness and communication in disorders of consciousness. We employed a P300 based BCI where healthy volunteers and patients with locked-in syndrome and in a minimally conscious state were asked to answer yes or no to simple questions by paying attention to one out of four auditorily presented stimuli (‘yes’, ‘no’, ‘stop’, ‘go’). Methods: We studied 13 patients with a minimally conscious state (MCS, 5 TBI – 8 anoxic, mean time post injury 70±109 months; mean age 42 ± 21) and 2 in pseudo-coma or locked in syndrome (LIS; brainstem stroke, time post injury 26 and 46 months; aged 63 and 29)) and 16 healthy controls (aged 45±19). Patients were evaluated using the Coma Recovery Scale Revised (CRS-R). An auditory P300 four choice speller paradigm (Furdea et al., 2009) based on the BCI2000 system (Schalk et al., 2004) was used. 16-Channel EEG was recorded using a g.tec USBAmp amplifier. A trial constituted of 15 presentation of four sounds the order of presentation being pseudo-randomized (sound duration: ~400ms; inter-stimulus interval: ~600ms). After a training session of 4 trials, patients and healthy subjects were required to answer 10 or 12 questions, respectively. Questions were of the following kind: “Is your name Quentin?”, “Is your mother’s name Dorothée?”. A stepwise linear discriminant analysis based on the training session was used to classify the data and to provide online feedback. Offline, all training and testing sequences were pooled. Sequences with artifacts were discarded and a leave-one-out approach was used to classify the data. Results: Healthy subjects presented a mean correct response rate of 73% online and 93% offline. Note that online classification failed for one control subject due to a presumed change in cognitive strategy between training and testing sessions. LIS patients showed a correct response rate of 30 and 60% (online) and 36 and 79% (offline). Three MCS patients had a correct response rate of ≥50% offline (10, 18, 0% online and 50, 53, 57% offline). Two of these three patients did not show any command following at the bedside. The 10 remaining MCS cases showed online and offline correct answers <50% (mean 33±9% online and 25±13% offline). Conclusion: Our auditory P300-based BCI permitted functional interactive communication in 15/16 controls (online) and in all offline. Our data obtained in patients with locked-in syndrome and disorders of consciousness demonstrate the potential clinical usefulness of the technique following coma but also show lower accuracy in patients as compared to healthy volunteers. This might be due to fluctuating attentional levels and exhaustibility in the MCS and to the suboptimal EEG recording quality due to movement, ocular and respiration artifacts in these challenging patients. Further algorithmic developments should include automatic artifact detection and single trial classification. Despite the need for further improvement in BCI devices adapted to post-coma patients, our results already indicate that MCS patients without any clinical sign of command-following can employ a yes-no speller offering the hope of functional interactive communication and a possibility for decision making and autonomy.

The integrated water resource management problems require studying efficiently seawater intrusion at local and regional scale and identifying in real time the seawater/freshwater interface dynamic. Hydrogeological modeling is widely used to predict seawater intrusion if additional natural or man‐made factors are modified. These models are currently calibrated using measured heads and salt mass fractions in boreholes, which generally result in sparse data coverage. Within this scope, non to minimally invasive geophysical techniques like electrical resistivity tomography (ERT) or time‐domain electromagnetic method are becoming increasingly popular, given their relatively greater spatial horizontal resolution compared to borehole observations. We present a comparison between both a sequential and joint approach to calibrate seawater intrusion models using ERT. The former consists of constraining hydrogeological parameters using ERT derived parameters and relies on sequential inversions of the geophysical and hydrogeological data using a given petrophysical relationship. The second approach in based on simultaneous inversion of petrophysical and hydrogeological data using electrical resistance data as data. It is performed by coupling an inversion code with two hydrogeological and geophysical modeling codes through a petrophysical conversion. This investigation was performed on a densitydependent flow and transport numerical (three/two‐dimensional) simulation study from complex and realistic heterogeneous models. In the sequential approach, the simulations showed that only the shallow salt concentration of the seawater/freshwater transition zone could be recovered for different time‐lapse, due to poorly resolved regions in depth. The capability of image appraisal indicators (cumulative sensitivity and resolution) has been analyzed to emphasize the discrepancy between the targeted and imaged parameter values. On the other hand, the preliminary coupled inversion avoids the regularization bias introduced by ERT and addresses the non‐stationarity of the petrophysical relationship. [less ▲]

Model refinements of non-linear magnetic circuits are performed via a finite element subproblem method. A complete problem is split into subproblems to allow a progression from 1- D to 3-D including linear to non-linear model corrections. Its solution is then expressed as the sum of the subproblem solutions supported by different meshes. A convenient and robust correction procedure is proposed allowing independent overlapping meshes for both source and reaction fields. The procedure simplifies both meshing and solving processes, and quantifies the gain given by each model refinement on both local fields and global quantities. [less ▲]

Whereas it is obvious that the failure process can vary from one firm to another (Argenti, 1976; D'Aveni, 1989; Laitinen, 1991), to date, few researchers have worked on the detection of several explanatory failure patterns. In addition, none of the reviewed research really focuses on small firms while their failure is important and particular (Haswell and Holmes, 1989). Considering these observations and on the basis of two complementary statistical analyses (Thiétart, 2003), this paper identifies, among a sample of 208 small distressed firms, a taxonomy of five explanatory business failure patterns, i.e. five homogeneous groups of small firms on the basis of the reasons for their failure. These five patterns are the following ones : shocked firms (1), firms serving other interests (2), apathetic firms (3), firms that fail after a punctual managerial error (4) and badly-managed firms (5). The results of this paper are consistent with previous literature but they shed new lights on the understanding of the reasons for small business failure. As the detection of the fundamental explanatory failure factors is the basis of failure prevention (Argenti, 1976), the identification of these patterns is of crucial importance for a better understanding and for a better prevention of this phenomenon.

This paper discusses the contribution of an additional feedback loop to the entrainment and the robustness of a circadian system. To quantify robustness, we perform a global analysis of the system's parameter space. We quantify the parameter region where the circuit displays an experimentally observed behavior, under entrainment. This global measure is comleted with a classification based on the phase response curve (PRC). For two models of circadian rhythms, we found that the one with two loops is more robust than the one with a single loop: the two-loop model shows better resilience to parameter perturbations and it has also a larger region where the PRC matches experimental PRCs of circadian oscillators.

Cette communication présente le fruit d’une recherche en langues modernes menée en collaboration avec neuf enseignants du secondaire dans des écoles proposant des formations qualifiantes et accueillant un public plutôt défavorisé par son milieu socio-économique ou au parcours scolaire davantage marqué par l’échec. Cette recherche a permis la création d’outils qui ont été expérimentés dans les classes partenaires et réajustés grâce aux retours des enseignants mais aussi des élèves de façon à diagnostiquer les difficultés récurrentes chez les apprenants (maîtrise des compétences et des savoirs linguistiques) et de tenter d’y apporter des solutions. Toutefois, il ne suffit pas d’identifier les lacunes d’un élève et lui proposer des pistes de remédiation pour améliorer la maîtrise de sa langue. Il faut le rendre conscient de ses forces et faiblesses et l’engager dans des démarches qui lui permettront de progresser, notamment par un apprentissage stratégique. Nous avons veillé à expliciter les stratégies de réception et de production qu’un élève peut utiliser lorsqu’il apprend une langue étrangère et qui restent sans doute encore trop souvent de l’ordre de l’implicite. Permettre aux élèves de prendre conscience de leurs difficultés et de s’autoréguler dans leur apprentissage est un enjeu d’équité essentiel car tous ne sont pas aidés, accompagnés dans leur réflexion par leur milieu familial.

In order to take into account the dynamic effects of molten metal during solidification, a methodology is presented to interface a metal solidification solver (coupled thermal mechanical metallurgical finite elements solver) with a specifically developed flow dynamics solver. (flow dynamics and thermics finite volume solver) The numerical set of tools is designed to be used for the simulation of bimetallic hot rolling mill rolls vertical spincasting. Modeling the industrial process for these products imply certain specifications on the numerical methods used, mainly due to the size of the geometrical domain, low Rossby & Ekman numbers, and a high Reynolds number.

A complete ichthyosaur rostrum with 124 associated teeth was recently discovered in Laux-Montaux locality, department of Drôme, southeastern France. The associated belemnites and ammonites indicate a late Valanginian age (Neocomites peregrinus Zone, Olcostephanus nicklesi Subzone) for this fossil, which consequently represents the first diagnostic ichthyosaur ever reported from Valanginian strata. Despite its incompleteness, this specimen is perfectly consistent with Aegirosaurus leptospondylus WAGNER 1853 and is therefore referred to this rare taxon. This specimen thus greatly increases the temporal and geographic biozones of this taxon, which was previously restricted to the Tithonian (Upper Jurassic) lithographic limestones of Bavaria (southern Germany). Moreover, it indicates that Late Jurassic ichthyosaurs actually crossed the Jurassic-Cretaceous boundary with a much lighter diversity drop than previously supposed. Finally, tooth morphology and wear pattern suggest that Aegirosaurus belonged to the “Pierce II/ Generalist” feeding guild sensu Massare (1987; 1997), which was hitherto not represented in post-Liassic ichthyosaurs.

In this paper, we describe a new automatic target recognition method for classifying targets according to their bistatic backscattering coefficients. The classification model is based on the construction of subspaces, one per target class. Results show an overall correct classification rate of about 83%, indicating that our method seems to be valid. Further improvements of the algorithm are also discussed. [less ▲]

Objective: In the recovery from coma, the acquisition of command following represents an important milestone, indicating emergence from the vegetative state. In some patients, recovery of consciousness may precede motor recovery. Brain-computer interfaces (BCI) might permit these patients to show non-motor dependent signs of awareness and in a next step might enable communication. This study aimed at testing to what extent an EEG-based BCI could help detecting signs of awareness and communication in disorders of consciousness. Methods: We studied 13 patients with a minimally conscious state (MCS, 5 TBI – 8 anoxic, mean time post injury 70±109 months; mean age 42 ± 21) and 16 healthy controls (aged 45±19). Patients were evaluated using the Coma Recovery Scale Revised. 16-Channel EEG was recorded using a g.tec USBAmp amplifier. An auditory P300 four choice speller paradigm based on the BCI2000 system was used. Subjects were asked to answer yes or no to simple questions by paying attention to one out of four auditorily presented stimuli (‘yes’, ‘no’, ‘stop’, ‘go’). A trial constituted of 15 presentations of each sound the order of presentation being randomized. After a training session, patients and healthy subjects were required to answer 10 to 12 questions. A stepwise linear discriminant analysis based on the training session was used to classify the data. Offline, all training and testing trials were pooled and a leave-one-out approach was used to classify the data. Results: Healthy subjects presented a mean correct response rate of 73% online and 93% offline. Three MCS patients had a correct response rate of ≥50% offline (10, 18, 0% online and 50, 53, 57% offline). Two of these three patients did not show any command following at the bedside. The 10 remaining MCS cases showed online and offline correct answers <50% (mean 33±9% online and 25±13% offline). Conclusion: Our auditory P300-based BCI permitted functional interactive communication in 15/16 controls (online) and in all offline. Our data obtained in patients with disorders of consciousness demonstrate the potential clinical usefulness of the technique following coma but also show lower accuracy in patients as compared to healthy volunteers. This might be due to fluctuating attentional levels and exhaustibility in the MCS and to the suboptimal EEG recording quality due to movement, ocular and respiration artifacts in these challenging patients.
