The genetic parameters of CH4 indicators were estimated by single trait test-day models from 16,825 records collected on Walloon Dual Purpose Belgium Blue cows in their first 3 lactations. Fatty acid based CH4 indicators published in the literature were predicted from milk mid-infrared spectra using 597 calibration samples. For the indicator showing the highest link (R2 =0.88) with SF6 CH4 data, the average daily heritability was 0.21, 0.20 and 0.10 for each lactation, respectively. The sire genetic variability was on average 2.82 kg2 of CH4 per lactation. The genetic difference between the sires having cows eructing higher and lower CH4 was 10 kg of CH4 averaged per lactation. In conclusion, CH4 indicators can be predicted by MIR and the genetic variability of these traits seems to exist. [less ▲]

Introduction : Le diabète atteint environ 3% de la population française. Or, cette maladie expose à l'apparition précoce de complications cardiovasculaires. Les troponines de nouvelles générations hautement sensibles pourraient être un bon outil diagnostic pour mettre en évidence des macroou micro-angiopathies non diagnostiquée chez ces patients. Le but de notre étude était de comparer la performance de la troponine T ultrasensible (hsTnT) (Roche Diagnostic) avec la troponine I ultrasensible (TnI II) (Abbott Diagnostic) chez le sujet diabétique. Matériel et méthodes : Vingt patients diabétiques (âge moyen : 52.6 ± 8.4 ans) ont été sélectionnés sur le critère d’un taux d’hémoglobine glyquée (HbA1c) élevé. Ces sujets ont été comparés à vingt sujets contrôles d’âge moyen : 60.05 ± 2.86 ans. Les patients atteints d’insuffisance rénale et d’affections cardiovasculaires ont été exclus. Les analyses ont été réalisées sur du plasma hépariné lithium. La hsTnT a été dosée par électrochemiluminescence sur le Modular E (Roche Diagnostic). Abbott utilise des microparticules chemiluminescentes pour le dosage de la TnI II sur l’ARCHITECT i. Résultats : Les sujets diabétiques ont un taux plasmatique de hsTnT représenté par les valeurs suivantes [médiane (1er quartile, 3ème quartile)] : 0,007 (0,03 ; 0,018) ng/mL ; alors que les sujets contrôles négatifs présentent les valeurs suivantes : 0,003 (0,003 ; 0,004) ng/mL. La différence de taux de hsTnT observée entre ces 2 populations est statistiquement significative (p = 0,000922). Pour la TnI II, on observe un taux plasmatique de: 0,004 (0,003 ; 0,075) ng/mL chez les sujets diabétiques et 0,002 (0,001 ; 0,005) ng/mL chez les sujets contrôles. La différence de taux de TnI II observée entre ces 2 populations n’est pas statistiquement significative (p > 0,005). Discussion-conclusion : Au décours d’un diabète, il apparait que les taux de hsTnT sont augmentés de façon significative par rapport au groupe des contrôles négatifs. Si les taux hsTnT augmentent chez le diabétique, il semblerait normal qu’il en soit de même pour la TnI II, vu que ces deux marqueurs sont intimement liés. Nous ne l’avons pas observé mais ceci peut être du à la plus faible performance analytique du dosage de la TnI II utilisé. Cette libération de hsTnT dans le sang peut être due aux micro- et macro-angiopathies au niveau des coronaires induites au cours d’un diabète. [less ▲]

Introduction Un acide gras (AG) est un acide carboxylique avec une longue chaine aliphatique, qui peut être saturé ou insaturé. Récemment, le rôle des AG, particulièrement, celui des oméga-3 et oméga-6, a émergé comme facteur de risque cardiovasculaire dans la littérature. Le but de ce travail était de comparer les taux d’AG mesurés dans une population saine avec ceux obtenus chez des patients admis aux urgences pour un infarctus du myocarde. Matériels et méthodes Cinquante quatre sujets sains (33±11ans, 31 femmes) ont été sélectionnés comme population de référence. Ces derniers ont été sélectionnés selon leur mode de vie (alimentation, tabac, etc). En parallèle, nous avons dosé les AG chez 33 patients (55±9 ans, 12 femmes) admis dans le service d’urgence de notre institution pour infarctus aigu du myocarde (AMI). Le sang était prélevé sur EDTA. Avant l’analyse, les échantillons étaient lavés et transméthylés. Le dosage des AG était réalisé par chromatographie gazeuse couplée à un détecteur à ionisation de flamme (GCFID). Après le dosage, nous avons réalisés une comparaison des taux, sommes et rapport entre les différents AG ainsi que l’index oméga-3 (somme de l’acide eicosapentaénoïque et docosahexaénoïque) obtenus dans les 2 groupes. Résultats. Des valeurs de référence ont été obtenues pour notre population de référence via le logiciel de statistique MedCalc. Dans le groupe AMI, les taux d’oméga-6 étaient significativement plus élevés (p<0.05) pour C18:2n6 (Figure 1) et C18:3n6 (Figure 2)comparés aux résultats obtenus dans la population de référence. Par contre les taux d’oméga-3 étaient significativement plus bas (p<0.01) par rapport aux sujets de référence pour le C22 :6n3 (Figure 3). L’index oméga-3 montrait une valeur plus basse et le rapport oméga-6/oméga-3 était plus élevé dans le groupe AMI comparé aux sujets de référence. Conclusion Le dosage des AG est un nouvel outil que le laboratoire peut proposer aux cliniciens afin de stratifier les patients présentant le plus de risque cardiovasculaire avant ou après un infarctus du myocarde. Ces patients pourraient ainsi être supplémenté en acides gras oméga-3 afin d’éviter les récidives d’infarctus du myocarde ou de diminuer la formation de la plaque d’athérosclérose avant le premier accident.

This paper describes recent advances in prediction software using advanced data-mining tools, and shows how this can significantly increase the operational value of the data gathered. These new tools allow for new operational procedures to be defined that increase the usages of the network without decreasing security of supply. We will use the example of dynamic line rating, i.e. determining the thermal rating of an overhead line based on real-time environmental parameters (temperature, wind speed & direction and solar radiation) to highlight how the use of numerical data-mining tools can help us reliably predict future behavior of power networks.

The European Space Agency (ESA) is planning a Lunar Lander mission in the 2018 timeframe that will demonstrate precise soft landing at the polar regions of the Moon. To ensure a safe and successful landing a careful risk analysis has to be carried out. This is comprised of identifying favorable target areas and evaluating the surface conditions in these areas. Features like craters, boulders, steep slopes, rough surfaces and shadow areas have to be identified in order to assess the risk associated to a landing site in terms of a successful touchdown and subsequent surface operation of the lander. In addition, global illumination conditions at the landing site have to be simulated and analyzed. The Landing Site Risk Analysis software framework (LandSAfe) is a system for the analysis, selection and certification of safe landing sites on the lunar surface. LandSAfe generates several data products including high resolution digital terrain models (DTMs), hazard maps, illumination maps, temperature maps and surface reflectance maps which assist the user in evaluating potential landing site candidates. This paper presents the LandSAfe system and describes the methods and products of the different modules. For one candidate landing site on the rim of Shackleton crater at the south pole of the Moon a high resolution DTM is showcased. * Corresponding [less ▲]

Cet article s'intéresse à la relation entre narration et communication. Il suggère que la frontière réel/fiction serait non pertinente relativement à une « efficacité » ou à une « réussite » de la communication. Plus précisément, il suppose que la non pertinence de l’opposition réel/fiction est au cœur de la réussite de la communication elle-même : telle est la seconde thèse. Encore faudra-t-il auparavant s’être entendu sur ce qu’est une communication « réussie », et pour ce faire reconsidérer cette question, en établissant une relation de dépendance réciproque entre ses « rites », qui cadrent et limitent l’interaction ainsi que l’a montré Goffman, et ses « risques » que sont la possibilité du dérapage, de la sortie du cadre, voire la difficulté à établir un cadre. C'est là la première thèse : pas de rites sans risques, et ce non pas parce l’échec ou l’accident pourraient toujours survenir, mais parce qu’ils sont constitutifs du rite lui-même. En définitive, cet article s'attache à montrer que l’échec de la communication est l’une des conditions de sa réussite, et qu’il est au cœur de la possibilité de la narration ainsi que de sa lecture.

Over the last decade ground-based remote sensing measurements of CO2 have been established as an important component in the global observing system for greenhouse gases. Since 2004 the Total Carbon Column Observing Network (TCCON) sites have provided CO2 retrievals in the near-IR region. CO2 can also be retrieved in the mid-IR spectral region and it would be of great benefit to use these spectra to produce CO2-data of sufficient precision. With this, 20 years of additional observations obtained in the mid-IR at a suite of FT-IR sites of the Network Detection of Atmospheric Composition Change (NDACC) will be accessible. We investigated a series of different CO2 microwindows in the mid-IR spectral region and present results from the most promising candidates for a showcase FT-IR site (Ny Alesund). Limitations of the approach are outlined and the feasibility of a future Mid-IR CO2-product of sufficient precision is discussed. [less ▲]

Substrate limitation responsive biosensors have been used in order to detect spatial substrate heterogeneities, , inside industrial bioreactors (whole-cell biosensor). Three green fluorescent protein (GFP) transcriptional reporters have been chosen in E.coli, i.e. uspA::gfp, csiE::gfp and yciG::gfp. The promoter uspA is induced in response to a variety of stresses whereas the two other promoters, csiE and yciG, are supposed to be more specific in front of a substrate limitation. The responsiveness of these biosensors has been assessed in chemostat reactor. Secondly, the same biosensors have been tested in well-mixed laboratory reactors and in scale-down reactors able to reproduce industrial conditions. Finally, a mini scale-down platform has been proposed as a high throughput tool to investigate rapidly the usefulness of a given microbial biosensor. Local heterogeneities in mini-bioreactor have caused a decrease of GFP expression, as in scale-down reactor. The presence of GFP in supernatants was noticed and this leakage seems to be correlated with the membrane permeability. [less ▲]

The aggregative behaviour of the multicoloured Asian ladybeetle, Harmonia axyridis Pallas, during winters, is still misunderstood. Our study was focused on the chemical and physical factors involved in the selection of its aggregation sites. Chemical and behavioural analyses highlighted that long-chain hydrocarbons lead congeners towards aggregations and ensure the cohesion of the cluster. On the other hand, we investigated the influence of (1) the density of individuals and (2) the quality of available shelters on H. axyridis decision to settle and aggregate under shelters. A binary choice experiment conducted in laboratory highlighted a permanent aggregative behaviour of H. axyridis, even during non-wintering conditions, and the existence of social interactions between individuals.

Long-term series of tropospheric water vapour amounts and HDO/H2O ratio profiles above Jungfraujoch

Water vapour is a crucial climate variable involved in many processes which widely determine the energy budget of our planet. In particular, water vapour is the dominant greenhouse gas in the Earth’s atmosphere and its radiative forcing is maximum in the middle and upper troposphere. Because of the extremely high variability of water vapour concentration in time and space, it is challenging for the available relevant measurement techniques to provide a consistent data set useful for trend analyses and climate studies. Schneider et al. (2006a) showed that ground-based Fourier Transform Infrared (FTIR) spectroscopy, performed from mountain observatories, allows for the detection of H2O variabilities up to the tropopause. Furthermore, the FTIR measurements allow the retrieval of HDO amounts and therefore the monitoring of HDO/H2O ratio profiles whose variations act as markers for the source and history of the atmospheric water vapour. In the framework of the MUSICA European project (Multi-platform remote Sensing of Isotopologues for investigating the Cycle of Atmospheric water, http://www.imk-asf.kit.edu/english/musica.php), a new approach has been developed and optimized by M. Schneider and F. Hase, using the PROFFIT algorithm, to consistently retrieve tropospheric water vapour profiles from high-resolution ground-based infrared solar spectra and so taking benefit from available long-term data sets of ground-based observations. The retrieval of the water isotopologues is performed on a logarithmic scale from 14 micro-windows located in the 2600-3100 cm-1 region. Other important features of this new retrieval strategy are: a speed dependant Voigt line shape model, a joint temperature profile retrieval and an interspecies constraint for the HDO/H2O profiles. In this contribution, we will combine the quality of the MUSICA strategy and of our observations, which are recorded on a regular basis with FTIR spectrometers, under clear-sky conditions, at the NDACC site (Network for the Detection of Atmospheric Composition Change, http://www.ndacc.org) of the Jungfraujoch International Scientific Station (Swiss Alps, 46.5°N, 8.0°E, 3580m asl). Information content analysis of the retrieved H2O products allows us to produce a long-term trend from 1996 to 2011 for different tropospheric levels. We will compare the annual cycle of tropospheric HDO/H2O ratio profiles with those already produced at other sites (Schneider et al., 2010). We will also focus on the diurnal variability of water vapour to determine a time limit in the inter-comparison of different water vapour measurement techniques. [less ▲]

The determination of isotopic ratios in comets is of primary importance for a good understanding of their origin and the formation of solar system. The [SUP]14[/SUP]N/[SUP]15[/SUP]N ratio is an interesting tracer, because of its variability among various solar system bodies. So far it has only been measured in bright comets through optical observations of the CN radical (Arpigny et al., 2003; Manfroid et al., 2009) and millimeter observations of HCN (Bockelée-Morvan et al., 2005, 2008). The measurements give for both species the same non-terrestrial isotopic composition ([SUP]14[/SUP]N/[SUP]15[/SUP]N≈150 in comets versus 272 in the Earth atmosphere), but HCN and CN are minor species. In order to get a determination of this ratio in another molecule we have searched for [SUP]15[/SUP]NH[SUB]2[/SUB] lines in a high-resolution and high signal-to-noise ratio spectrum of comet C/2002 T7 (LINEAR) obtained with the UVES spectrometer at the VLT ESO 8-m telescope (Hutsemékers et al., 2008). This work is based on a new laboratory experiment conducted with the AILES beamline spectrometer at synchrotron SOLEIL to determine the [SUP]15[/SUP]NH[SUB]2[/SUB] wavelengths by Fourier transform spectroscopy. We will present the first results obtained from these data, which have allowed to search for the first time [SUP]15[/SUP]NH[SUB]2[/SUB] emission lines in a comet.

Despite the great uncertainties regarding the future climatic context, lots of studies have focused on hydrological effects of climate change on the Meuse catchment. It appears that both winter high flows and summer low flows could be exacerbated. Climate change and its impacts on hydrology will thus affect various socio-economic sectors. High flows have been widely studied compared to low-flows. This poster will put the emphasis on a methodology developed in order to study impacts of droughts on agriculture. Agriculture is among the most impacted sectors due to climate change. The consequences could be both positive as negative in accordance with the range of predicted changes and the adaptation capacity of agricultural systems. Most of the existing studies related to climate change on agriculture focused on specific territory. Within the AMICE Interreg IVB project, a transnational approach has been developed to assess droughts impacts on agriculture through the Meuse basin. The project’s previous works gave us a common scenario of climate trends and of the evolution of the hydrology in the Meuse basin. The methodology is based on the use of a physically-based model able to simulate the water-soil-plant continuum (derived from EPIC model). In order to be transferable from one country to another, the methodology proposed used data available at the basin scale. The UE soil data base was complemented with local information on agricultural practices and statistics. Three crops have been studied: maize, wheat and barley. The basic cultural calendar is supposed to be the same for the different countries. The methodology developed permits to study the evolution of yields, leaf area index, crops stress due to excess or lack of water through time under different scenarios build up in the frame of the project. It appears that corn is negatively affected by climate change, and thus despite the CO2 fertilization effect. Wheat and barley have similar behavior and are positively affected by climate change and CO2 fertilization. Leaf Area Index study reveals that the different crops start earlier and reach earlier maturity. These first results will be completed with other economic sectors’analysis like drinkable water production, electricity production and navigation. Therefore, the project will progress towards a better understanding of economic effects of future droughts and low-flows. [less ▲]

Nowadays, tillage simplification is an increasing practice. Many advantages are cited in the literature, such as energy saving, soil conservation etc. Agricultural management practices influence soil structure, but consequent changes in soil hydrodynamic behaviour at the field scale are still not well understood. Many studies focus only on macroscopic measurements which do not provide mechanistic explanations. Moreover, research shows divergent conclusions over structure modification. The aim of this work is to fill this gap by quantifying soil structure modification depending on tillage intensity through both macroscopic and microscopic measurements, the latter improving our comprehension of the fundamental mechanisms involved.

The verbal overshadowing effect (VO) (eg, Schooler and Engstler-Schooler, 1990 Cognitive Psychology 22(1) 36–71) suggests that the fact of generating a verbal description of a previously seen face may impair subsequent performance on a lineup identification task in adults. Previous research has examined whether descriptions also impaired children’s identification abilities but no evidence of VO was found (Memon and Rose, 2002 Psychology, Crime and Law 8(3), 229–242). However, the method might not have been appropriate to observe this effect as, for instance, a 24-hour delay between the description and the identification tasks (associated with a release of the VO effect in adults) was used. Hence, in this current experiment, groups of children (7–8, 10–11, 13–14 years old) and adults were presented with a short video and then assigned to a description or a no description condition before the identification task. Participants were also assigned either to a “no delay”, a “24-hour post encoding delay” or a “24-hour post description delay” condition to determine the influence of delay on the VO effect. Results indicated that, compared to the control condition, the description decreased correct identification performance in both children and adults and no release of VO was found with delay.

At the time when the significance of water becomes more than obvious, we realize the utility of models that describe hydrological phenomena and that permit the optimization of water management. The soil properties, as they have an influence both on hydrology and on plant development, are an element really essential in this type of model. But, as for tree characteristics, these properties are spatially and temporally variable. Therefore this research will specially focus on the case of forested slopes. The study will be divided into three parts. The first will characterize the vertical and the horizontal heterogeneity of the structural and hydrodynamic properties of soil. To do this, in addition to the analysis of the soil sampled along the slope, moisture sensors will be installed on different places on a slope and on different depths. For the greatest part it will be capacitive sensors whose values will be confirmed by TDR sensors. Each sensor will be inserted to cover the largest pedological and topographic variability. The second part of the study will permit to characterize the water flux repartition into the horizons down the slope. We will therefore apply a dye to surface on the top of the slope. The bottom of the slope will be equipped with an experimental system which collects water for each soil layer. The third parts will deal with the forest stand heterogeneity along the slope. We will measure characteristics such as tree height, roots repartition, stem circumference and also for different periods of the year, leaf area index (LAI). At the end of the research, we will measure tree rings for a dendrochronolocical study. The collected data will be analyzed to determine the slope effects on the soil properties, on the water flux distribution into the soil layer and on the tree characteristics. Afterwards the relations and the interactions can be conceptualized and introduced into a physical hydrological model. The studied slope is located on the Houille watershed in the West of the Belgian Ardenne. The site is situated under a Douglas fir cover (Pseudotsuga menziesii (MIRB.) FRANCO). It is about 170 meters long with an average slope of 25%. There are only few studies that attempt to connect physical models and the tree growth at the slope scale, leaving a vast untapped investigation area in the hydrological modelling. The study of this variability would afford possibility to improve hydrological models. From the point of view of the climate change, such a model would e.g. determine the best adapted species to each forest site. [less ▲]

Appel au peuple/appel du public : décrire la réception comme une adresse

Par rapport à d'autres productions culturelles ou scientifiques, la particularité des médias de masse est qu'ils font quelque chose au peuple en faisant quelque chose du peuple, c'est-à-dire en le représentant à lui-même. La construction mass-médiatique du "peuple" a donc une dimension pragmatique que les études de réception doivent intégrer. C'est à quoi s'attache cette communication, notamment à travers la notion d'adresse, issue du travail de J. Derrida, et celle de "partage du sensible" formalisée par Jacques Rancière. [less ▲]

Alzheimer’s disease (AD) is characterised by altered recollection function, with impaired controlled retrieval of associations. In contrast, familiarity-based memory for individual items may sometimes be preserved in the early stages of the disease. This is the first study that directly examines whole brain regional activity during one core aspect of the recollection function: associative controlled episodic retrieval (CER), contrasted to item familiarity in AD patients. Cerebral activity related to associative CER and item familiarity in AD patients and healthy controls (HC) was measured with functional magnetic resonance imaging during a word-pair recognition task to which the process dissociation procedure was applied. Some patients had null CER estimates (AD–), whereas others did show some CER abilities (AD+), although significantly less than HC. In contrast, familiarity estimates were equivalent in the three groups. In AD+, as in controls, associative CER activated the inferior precuneus/posterior cingulate cortex (PCC). However, during associative CER, functional connection between this region and the hippocampus, the inferior parietal and dorsolateral prefrontal cortex (DLPFC) was significantly higher in HC than in AD+. In all three groups, item familiarity was related to activation along the intraparietal sulcus (IPS). In conclusion, whereas the preserved automatic detection of an old item (without retrieval of accurate word association) is related to parietal activation centred on the IPS, the inferior precuneus/PCC supports associative CER ability in AD patients, as in HC. However, AD patients have deficient functional connectivity during associative CER, suggesting that the residual recollection function in these patients might be impoverished by the lack of some recollection-related aspects such as autonoetic quality, episodic details and verification.

Comet 8P/Tuttle was the target of an ESO multiwavelength observing campaign in 2008. Observations of the spatial distribution of C2 and C3 were obtained, as well as simultaneous direct detections of the C2 parent species C2H2 and C2H6. We combine these observations to investigate the origin of cometary C2. The observed C2 column densities are inconsistent with a production of C2 from C2H2, C2H6, and C3. Based on a photochemical model, we quantitatively discuss the influence of further potential C2 parent species. The assumption of C4H2 as an additional C2 parent species in comet 8P/Tuttle provides the best explanation for the observed C2 column densities. [less ▲]

Seeking for the optimum retrieval strategy of methanol (CH3OH) from ground-based high-resolution FTIR solar observations recorded at the high-altitude Jungfraujoch station (46.5ºN)

Methanol (CH3OH) is a key organic compound in the Earth’s troposphere, with reported concentrations of the order of a few ppbv. It is indeed the second most abundant organic atmospheric compound after methane (Jacob et al., 2005). The same authors have estimated its lifetime to a few days. Natural sources of CH3OH include plant growth, oceans, decomposition of plant matter, oxidation of methane,. . . They are complemented by anthropogenic (from vehicles, industry) and biomass burning emissions. Oxidation by the hydroxyl radical is the main sink, leading to the formation of carbon monoxide (CO) and formaldehyde (H2CO) (Rinsland et al., 2009; Stavrakou et al., 2011, and references therein). The first retrievals of methanol from ground-based Fourier Transform Infrared (FTIR) spectra have been reported by Rinsland et al. (2009), using spectra recorded at Kitt Peak (31.9ºN) and a microwindow extending from 992 to 999 cm-1. Soon after, Stavrakou et al. (2011) used another spectral interval from 1029 to 1037 cm-1, for methanol retrievals at Reunion Island (21ºS). In both cases, lines of the strong nu8 band of CH3OH were adjusted, accounting for interferences by several isotopologues of ozone and by water vapor. In this contribution, we will present first retrievals of CH3OH from observations recorded at the high-altitude station of the Jungfraujoch (46.5ºN, 8ºE, 3580 m asl), with a Bruker 120HR spectrometer, in the framework of the Network for the Detection of Atmospheric Composition Change (NDACC, visit http://www.ndacc.org). We will implement existing retrieval approaches –and possibly additional one(s)– to determine which strategy is the most appropriate for our dry high-altitude site. If successful, a long-term CH3OH total column time series will be produced using the Jungfraujoch observational database, and we will perform preliminary investigations to characterize the seasonal and inter-annual variations of this species at northern mid-latitudes.

In the standard seesaw model, finite corrections to the neutrino mass matrix arise from one-loop self-energy diagrams mediated by a heavy neutrino. We discuss the impact that these corrections may have on the different low-energy neutrino observables paying special attention to their dependence with the seesaw model parameters. It is shown that sizable deviations from the tri-bimaximal mixing pattern can be obtained when these corrections are taken into account. [less ▲]
