Le vaste ensemble sculpté constitué par les trois portails occidentaux de la cathédrale de Strasbourg a fait l’objet, ces dernières années, de plusieurs études. Une critique d’authenticité a été menée ; les choix iconographiques qui ont présidé à l’élaboration du programme ont été déterminés et justifiés. Toutes ces études ont pourtant laissé de côté une centaine de reliefs finement sculptés qui agrémentent les parties hautes du niveau des portails, à l’extérieur comme à l’intérieur de la façade. Cette iconographie, authentique pour l’essentiel, se distingue par une grande variété de « sujets ». A priori, elle rappelle celle des « drôleries » des manuscrits de la fin du XIIIe siècle et du XIVe. Mais est-ce le cas ? Et si c’est le cas, comment articuler ces sujets qui ont jusqu’à aujourd’hui été considérés comme marginaux, avec l’iconographie des ébrasements, des tympans et des voussures ? Enfin, l’ensemble de « drôleries » de la cathédrale de Strasbourg peut-il, d’un point de vue iconographique, être comparé à d’autres ensembles sculptés français et germaniques de la fin du XIIIe siècle et du XIVe ?

Bovine Respiratory Disease, or BRD, are common in young cattle in the first year of life but occurs mainly before 6 months. A peak of incidence is noticed between 2-10 weeks, due to a decline of immunity. BRD is associated with the well-known shipping-fever that may come from cumulative stress. This condition can reach 5-20% case fatality rate and a morbidity rate up to 100%. Most of the time, the treatment administered is effective. In other cases, a relapse within 2 weeks, associated or not with mortality, can be observed. BRD induces economic losses with treatments (antibiotics), prevention (vaccination) and mortalities. There are also zootechnical consequences with growth retardation, circulation of infectious agents, and increased sensitivity to other pathogens. Cattle are more susceptible to BRD for many reasons. They have narrow upper airways that increase air speed and allow a deeper colonization of particles in the lower respiratory tract. There is also a link between the digestive and respiratory system in bovines. Inhalation of eructation gaz occurs regularly. The respiratory tract in cattle is more sensitive to endotoxins. In case of rumen acidosis, a paralysis of the mucociliary escalator is observed. Finally, cases such liver abscess or Vena Cava Caudale thrombosis, a metastatic pneumonia can follow. BRD often begins with virus attack, which may be complicated with surroundings bacterial infections. Among the different viral aetiologies, Bovine Respiratory Syncytial Virus (B-RSV), Parainfluenza virus (PI-3), Bovine Herpes Virus (BHV-1 or IBR), Bovine Viral Diarrhoea Virus (BVD, for its immunosuppression effect) are the most frequent encountered. Adenovirus and Coronavirus, BHV-4, Rhinovirus, Reovirus, and Enterovirus can also be present, in a lesser extent. Among bacteriological causes, Mannheimia haemolytica, Pasteurella multocida, Histophilus somni, Trueperella pyogenes, and Mycoplasma bovis (dispar) are commonly met. Chlamydophila and Salmonella dublin can sometimes also provoke pneumonias. An onset of BRD can begin with only an increased rectal temperature. That is why it is recommended to the owner to check for temperature in the different batches of animals. After, other symptoms will appear, such as cough, nasal discharge, dyspnea, etc. BRD can be categorized in 4 clinical grades, from 1 to 4, according to the severity of the disease. Grade I does not need a treatment, as well as grade IV that is so severe that the animal may probably die within a few days. Other scores exist and they also take into account symptoms such cough, rectal temperature, nasal discharge, etc. The grade or score of the disease is important to establish a treatment, a prognosis or an ancillary exam. Measurement of blood L-Lactate (with portable spectrophotometer, e.g. Accutrend-Plus, Cobas, ~150€ and ~3€/test) allows on the field the determination of the grade of BRD as well as prognosis. L-Lactate ≥ 4 mmol/L in calves with BRD (up to 13 months) is associated with grade IV BRD and poor prognosis (death within 3 days) with 95% sensitivity and 80% specificity (Coghe et al., 2000). Another study shows that L-Lactate > 3.7 mmol/L is associated with 44 times more risk to die in calves with BRD, compared to calves with L-Lactate <1.3 mmol/L (Buczinski et al., 2014). BRD is clearly a multifactorial disease. Its management must include the resistance of animal (genetic, nutrition, vaccination), the environment (ventilation, hygiene) and the identification of the infectious agents. This conference is focused on the last topic. [less ▲]

The human exposure to persistent organic pollutants (POPs) is a concern since these compounds are ubiquitous in the environment. This class of compounds group different families such as the polychlorodibenzo-p-dioxins (PCDDs), the polychlorodibenzofurans (PCDFs), the polychlorinated biphenyls (PCBs), the organochlorine pesticides (OCPs), and the halogenated flame-retardants (HFRs). Their use, their release in the environment, their presence in foodstuffs, as well as in various goods on the market are mostly regulated through international conventions, like the Stockholm convention on POPs, and at the European and national levels. Despite the proactive approach in order to reduce the overall exposure to POPs, levels of contaminants (even banned) are still found in the environment and in the human body. In this thesis, we developed several methods of analysis of POPs in different samples. The first was a confirmatory method for PCDD/Fs and PCBs analysis in food and feed following a new European Regulation No 709/2014 that recently allowed the use of gas chromatography (GC) coupled to triple quadrupole mass spectrometry (GC-QQQMS/MS) for this purpose. We fully validated the method on vegetable oil matrix around the maximum level of 1.50 ng WHO2005TEQ/kg. We showed that all analytical criteria, specific to this instrumentation, laid down by the Regulation were met, which indicates that the QQQMS/MS can successfully be used in the legal context for confirmatory purposes and could be an alternative to high-resolution sector field mass spectrometry (HRMS) in this context. The proper establishment of limits of quantitation was a key point in the discussion along with other analytical criteria proposed in the European Regulation, as new interpretations were necessary for the use of triple quadrupole mass spectrometry due to its different features from the HRMS. In addition, we developed in parallel a method for the analysis of Dechloranes in food. The measurement of ultra-trace levels of compounds from this emerging class of flame-retardants was possible after optimization of the injections parameters by means of experimental design, and of fragmentation pathways. Eventually, we reported relatively low levels in various food matrices and preliminary data about the significance of this route of exposure for humans. Besides food analysis, we developed a screening method to quickly assess levels of contaminants in human blood, involving a minimally invasive sampling technique and a couple of drops of blood. The instrumentation was first based on cryogenic zone compression (CZC) hyphenated to high-resolution time of flight mass spectrometry (HRTOFMS) applied to the analysis of two markers of exposure in regular dried-blood spots (DBS) typically used for newborn sampling. The second approach was based on GC-QQQMS/MS applied to the analysis of a broader range of OCPs and NDL-PCBs (30 analytes) in 40 µL blood. The blood was however collected using a novel Volumetric Absorptive MicroSampling (VAMS) method, directly inspired by the DBS but offering a control on the volume of blood sampled, hence opening the door to quantitation. The sample preparation of the VAMS dried sample was miniaturized and only 2 mL of solvents were necessary to prepare a sample, which makes it environmentally friendly. The focus was especially drawn to maximize the sensitivity via the optimization of the ionization energy and the electron multiplier voltage in order to reach appropriate low limits of quantitation. In this context of ultra-low volume of blood, background levels arose as the limitation of the method owing to the small signals coming from samples and closing the gap with blanks. Nevertheless, this patient-friendly approach is perfectly suitable for fast screening of population and could be useful in the context of UNEP campaigns where samples are hardly collected. [less ▲]

J’interrogerai la problématique du rapport de la traduction à la politique à partir de la notion de représentation politique, telle que thématisée par le théoricien argentin de l’analyse de discours, Ernesto LACLAU. Je commencerai très brièvement par resituer le processus de représentation dans le champ politique actuel. Cette re-contextualisation permettra de montrer que les notions de « représentation » et de « politique » entretiennent un rapport privilégié, mais qui ne se limite pas uniquement à sa forme contemporaine la plus répandue, symbolisée par nos institutions et principes politiques, tels le régime parlementaire ou encore l’élection. Je passerai alors au cœur de ma communication en dessinant la proximité conceptuelle et fonctionnelle de la traduction et de la représentation. Je me baserai, pour ce faire, sur les développements qu’Ernsto LACLAU a proposés de cette dernière, ainsi que sur quelques développements de Jean-René LADMIRAL et Willard Van Orman QUINE au sujet de la traduction. Je montrerai notamment (1) en quoi la conception de la représentation que propose LACLAU est un outil d’analyse pertinent de la politique, mais surtout (2) en quoi cette conception de la représentation est guidée par des processus traductifs. Je tenterai enfin, en guise de conclusion, de montrer en quoi l’on peut dégager de ce qui précède une perspective d’analyse supplémentaire, voire innovante, de l’articulation entre traduction, représentation et politique.

The airline industry changed dramatically in 1978 when it became deregulated. Operations research analysts played a critical role after deregulation by developing algorithms and decision-support systems designed to help airlines to maximize their revenue. More than thirty-five years after deregulation, the airline industry is faced with new challenges. The increased use of the Internet as the major distribution channel and the increased market penetration of low cost carriers have led to an increasing interest in using discrete choice models to model air travel demand as the collection of individual's decisions.
