Cette présentation aborde la question des genres et de leurs effets interprétatifs par le biais de l’énonciation et, plus particulièrement, par le biais des jeux de hiérarchisation énonciative dont peuvent faire l’objet divers genres de discours. Nous avons choisi de contraster deux genres de discours a priori très différents (discours politique et littéraire) de manière à dépasser la conception du genre comme un ensemble de données situationnelles ou textuelles, pour y voir un double principe de transfert entre ces deux ensembles. Entre la situation et le texte, le genre (roman, témoignage, harangue, etc.) impose certaines routines communicationnelles ; entre le texte et la situation, c’est d’une autre définition du genre dont on a besoin, celle du genre comme activation d’un parcours au sein d’un espace de possibles interprétatifs, donnant ainsi au texte une orientation argumentative, une consistance évènementielle et une valeur d’acte performatif. Nous pensons que dans cette seconde acception, le genre – ici, l’effet politisant – est susceptible de généralisation, tout comme le sont les genres envisagés plus traditionnellement à partir du pôle de la production.

Recent investigations reveal, in marine ecosystems, an ecohydrodynamic hierarchical organization resulting from the different rates of ecological processes confronted to a multi-scale physical environment. Major marine hydrodynamic processes are briefly analyzed here in an ecohydrodynamic perspective, emphasizing the effects they have on ecosystems at different levels of hierarchy and identifying appropriate “spectral windows” for modelling. A case study application to the Northern Bering Sea's Summer Ecohydrodynamics is given in illustration. [less ▲]

Based on systematic observations regarding the encoding of hieroglyphs in an electronic corpus, specifically the Ramses corpus (ramses.ulg.ac.be), the aim of this presentation was to introduce and discuss the data-model of the Thot Sign-List (under development at the university of Liège) and to present online resources made available for documenting the elements of this model (http://thot.philo.ulg.ac.be/index.html). Among the future goals is a strengthened collaboration between the AKU project and the Thot Sign-List (e.g., a shared hieroglyphic sign-list and a connection between the graphemes analysed by the AKU project and the texts of Ramses Online).

In this paper, we review issues related to the existing hieroglyphic sign-lists, focusing especially on the problematic aspects of the 'Manuel de Codage' (1988) and of the so-called 'Hieroglyphica' (2000) for font-designers and users alike. We propose and discuss a data model for the Thot Sign-List (TSL, in prep.). This data model shall lead to the implementation of a structured and systematically referenced hieroglyphic repertoire, which should ultimately allow a sound extension of the Egyptian Hieroglyphs in Unicode.

The aim of this paper is to suggest a taxonomy that allows for a systematic description of the functions that can be fulfilled by hieroglyphic signs. Taking as a point of departure the insights of several studies that have been published on the topic since Champollion, we suggest that three key-features – namely, semography, phonemography and autonomy – are needed in order to provide a description of the glottic functions of the ancient Egyptian graphemes. Combining these paradigmatic and syntagmatic features, six core functions can be identified for the hieroglyphic signs: they may behave as pictograms, logograms, phonograms, classifiers, radicograms or interpretants. In a second step, we provide a definition for each function and discuss examples that illustrate the fuzziness between these core semiotic categories. [less ▲]

HIF-1 is the main transcription factor responsible for increased gene expression in hypoxia: VEGF, erythropoietin, GLUT-1, and glycolytic enzymes are such target genes and all participate in the adaptative response of cells to hypoxia. AP-1 activation by hypoxia has also been demonstrated in several cell lines and it cooperates with HIF-1 for increasing VEGF gene transcription in hypoxia. Both HIF-1 and AP-1 activation by hypoxia seems to involve members of the MAP kinase family. Here, we summarize the data indicating that ERK and JNK are needed for activation of HIF-1 and AP-1, respectively. [less ▲]

High-resolution far-infrared and sub-millimetre spectroscopy of water lines is an important tool to understand the physical and chemical properties of cometary atmospheres. We present observations of several rotational ortho- and para-water transitions in comet C/2008 Q3 (Garradd) performed with HIFI on Herschel. These observations have provided the first detection of the 2[SUB]12[/SUB]-1[SUB]01[/SUB] (1669 GHz) ortho and 1[SUB]11[/SUB]-0[SUB]00[/SUB] (1113 GHz) para transitions of water in a cometary spectrum. In addition, the ground-state transition 1[SUB]10[/SUB]-1[SUB]01[/SUB] at 557 GHz is detected and mapped. By detecting several water lines quasi-simultaneously and mapping their emission we can constrain the excitation parameters in the coma. Synthetic line profiles are computed using excitation models which include excitation by collisions, solar infrared radiation, and radiation trapping. We obtain the gas kinetic temperature, constrain the electron density profile, and estimate the coma expansion velocity by analyzing the map and line shapes. We derive water production rates of 1.7-2.8 × 10[SUP]28[/SUP] s[SUP]-1[/SUP] over the range r[SUB]h[/SUB] = 1.83-1.85 AU.

We first review the standard Higgs mechanism of the standard model. Then, in the second chapter, we motivate the introduction of a second doublet in the theory. In the third chapter, we talk about the reasons to study the most general two Higgs doublet model and introduce the Minkowski formalism introduced by I.P. Ivanov to simplify this problem. Finally, we study the masses of the Higgs bosons in the most general two-Higgs-doublet model (2HDM) in a basis-independent approach. We adapt the recently developed Minkowski-space formalism to this problem and calculate traces of any power of the mass matrix in a compact and reparametrization-invariant form. Our results can be used to gain insight into the dynamics of the scalar sector of the general 2HDM. [less ▲]

Blubber samples from three delphinid species (false killer whale, Guiana and rough-toothed dolphin), as well as liver samples from franciscana dolphins were analyzed for dioxins and related compounds (DRCs). Samples were collected from 35 cetaceans stranded or incidentally captured in a highly industrialized and urbanized area (Southeast and Southern Brazilian regions). Dioxin-like PCBs accounted for over 83% of the total TEQ for all cetaceans. Non-ortho coplanar PCBs, for franciscanas (82%), and mono-ortho PCBs (up to 80%), for delphinids, constituted the groups of highest contribution to total TEQ. Regarding franciscana dolphins, significant negative correlations were found between total length (TL) and three variables, ΣTEQ-DRCs, ΣTEQ-PCDF and ΣTEQ non-ortho PCB. An increasing efficiency of the detoxifying activity with the growth of the animal may be a plausible explanation for these findings. This hypothesis is reinforced by the significant negative correlation found between TL and PCB126/PCB169 concentration ratio. DRC concentrations (ng/g lipids) varied from 36 to 3006, for franciscana dolphins, as well as from 356 to 30776, for delphinids. The sum of dioxin-like and indicator PCBs varied from 34662 to 279407 ng/g lipids, for Guiana dolphins from Rio de Janeiro state, which are among the highest PCB concentrations ever reported for cetaceans. The high concentrations found in our study raise concern not only on the conservation of Brazilian coastal cetaceans, but also on the possibility of human health problem due to consumption of fish from Brazilian estuaries.

Perfluorooctane sulfonate (PFOS) and other perfluoroalkyl compounds (PFCs) were measured in liver samples from 29 marine tucuxi dolphins from Rio de Janeiro state (RJ), Brazil. PFC measurement combined liquid chromatography and mass spectrometry, using a CapLC system connected to a Quadrupole- LIT mass spectrometer. PFOS was the only PFC detected and it was so in all samples. PFOS concentrations (ng ·g-1 dw) of dolphins (n)23) from the highly contaminated Guanabara Bay (in RJ) varied between 43 and 2431 as well as between 76 and 427 from areas of RJ other than the quoted bay (n ) 6). Concentrations of three fetuses and one neonate varied between 664 and 1590. Fetus/mother ratios were calculated in two situations (2.75 and 2.62). It seems that mother-to-calf transference plays important role for relationships between PFOS and age. When a one-year-old male calf presenting 2431 ng ·g-1 dw was excluded from the test, significant correlations were observed between PFOS concentrations and both age and total length. Despite the placental transference, PFOS concentrations were not significantly lower in females than in males. PFOS levels in marine tucuxi dolphins from Guanabara Bay are among the highest detected to date in cetaceans, andthismayrepresentathreat to the small population concerned. [less ▲]
