Communication présentée lors du LXIième congrès de la Société Française de Phoniatrie et des Pathologies de la Communication; Paris, le 9 octobre 2005. Our knowledge of vocal fold structure has profoundly evolved since the description by M.Hirano in 1974 of the laminar organization of the connective tissue of the human vocal fold , the lamina propria. The molecular composition of the extracellular matrix (ECM) of the lamina propria is essential in determining the viscoelastic properties of the tissue. This is particularly true in the superficial layer of the lamina propria ( also called Reinke’s space). With the epithelium, Reinke’s space constitutes the vocal fold main vibrator. In normal subjects, the jelly like structure of the Reinke’s space is due to a very loose fibrous scaffolding and to a balance between the interstitial proteins of the ECM : proteoglycans like decorin and hyaluronic acid and glycoproteins like fibronectin. Vibratory trauma leads , in disease states , to molecular modification of the extracellular matrix of Reinke’s space resulting in benign cordal lesions like nodules, submucosal fibrosis and vocal folds scars. Improving the knowledge of the homeostasis of Reinke’s space ECM can lead to improvement of the therapeutic and prevention strategies of vocal fold benign lesions. The main histologic and viscoelastic characteristics, as well as surgical treatment of cordal nodular lesions and scars are described. The recent researches in the field of regeneration of Reinke’s space are evoked. Rappel des connaissances de la microstructure cordale normale( et en particulier de la structure laminaire de la corde vocale ainsi que la répartition particulière des protéo- et glycosaminoglycans) , de l'altération de celle-ci en cas de nodule cordal et de cicatrice cordale. Implications thérapeutiques en terme de technique microchirurgicale, en particulier implantation d'acide hyaluronique estérifié dans la plaie microchirurgicale afin de moduler le processus de cicatrisation [less ▲]

Our study showed the potential of a surrogate of the oesophageal pressure, the jaw motion, and a dedicated automatic analysis to diagnose the obstructive sleep apnoea and hypopnoea syndrome (OSAHS). Twentyfour patients were recorded in hospital settings and the jaw motion of fifteen of them was also recorded at home with an ambulatory device. The apnoea and hypopnoea index (AHI) of the gold standard, AHI_PSG, and the two AHI from the automatic analysis of the jaw motion, AHI_H (hospital) and AHI_A (ambulatory), were compared : AHI_PSG Vs AHI_H showed good correlation (r = 0.97) and under-estimation (slope p = 0.76). AHI_A Vs AHI_H revealed good reliability with r = 0.98 and slope p = 0.99. Finally, AHI_PSG Vs AHI_A showed very good accuracy of the diagnosis with sensitivity of 90% and specificity of 100%.

The next generation of infrared - sub mm space telescopes requires reflectors with large dimensions, high quality and, according to weight issues, are based on composite or new materials technology. The challenging tasks of on-ground testing are to achieve the required accuracy in the measurement of these reflectors shape and antenna structures and to verify their performance under simulated space conditions (vacuum, low-high temperatures). A holographic camera for the verification and validation of this type of reflector in a space environment is presented. A diffuser is implemented to measure the deformations of reflective surfaces in a more flexible way. The system has been made compatible with the vacuum conditions. Some elements of the holographic camera (camera lenses, CCD, crystal, optical fibre) have been adapted and tested under vacuum. The metrological certification of the whole system is realised by the measurement of a parabolic CFRP reflector with a 1.1 meter diameter. The results are compared to the one achieved with a high spatial resolution IR interferometer on the same reflector in laboratory conditions and under thermal vacuum conditions. This later test consists in measuring the deformations of the reflector between an initial state at a selected temperature and a final state at another temperature. The comparison between the high spatial resolution IR interferometer and this dynamic holographic method showed very good qualitative and quantitative agreement between the techniques, thus verifying the potential of this new Holographic approach.

This paper analyzes the ability of the Multiple Centrality Corrections (MCC) interior point algorithm to solve various classical optimal power flow (OPF) variants, namely: the minimization of generation cost, the minimization of active power losses, the maximization of power system loadability and the minimization of the amount of load curtailment. The performances of the MCC approach are assessed with respect to the predictor-corrector algorithm, which is widely recognized as the best interior point method based optimizer to date.

Prion cell tropism varies significantly among animal species, depending on both the agent strain and host-specific factors. For example, prions show high lymphotropism in scrapie infected sheep and vCJD, but little, if any, in sCJD or BSE. In particular, the BSE strain is associate with significant PrP-res accumulation in tonsils, spleen and appendix in humans, whereas, it is largely confined to the nervous system in infected cattle. So, it appears that, at least in the case of BSE and vCJD, host properties can influence the accumulation of the infectious agent in lymphoid organs. Given that the normal cellular prion protein (PrPC), is sine qua non for PrP-res formation and the development of TSE, it appears reasonable to hypothesize that tissue-specific PrPC properties may represent one of the host factors influencing the cell tropism of the infectious agent in human or bovine. We applied a western blot analyses to compare the relative percentage of the di-, mono- and unglycosylated PrPC (the so called glycoform ratio) as well as the expression of truncated PrPC forms in tissues from the central nervous system and lymphoid structures (lymphoid follicles, lymphocytes and follicular dendritic cells) of both bovine and human. We found that PrPC glycoform ratio is significantly different between cerebellum and medulla in both bovine and human. Moreover, the expression of truncated forms of PrPC (i.e. 21 and 18 kDa PrPC) was also significantly heterogenous according to the brain region investigated. PrPC was highly glycosylated in spleen and lymphoid follicles isolated from bovine tonsils, mesenteric lymph nodes, ileal and jejunal Peyer’s patches. After deglycosylation, a novel PrPC truncated form with a relative molecular mass of about 25 kDa was detected in bovine lymphoid organs beside the typical 18 and 21 kDa forms. No difference in WB PrPC profile was seen in human lymphocytes extracted either from spleen or tonsil. Our results highlight variation in the profile expression of PrPC in peripheral and central tissues of bovine and human. Such differences may have an implication for PrPC function or may represent critical factors influencing the accumulation of the infectious agent in these areas.

This paper presents an intermediate approach between parametric shape optimization and topology optimization. It is based on using the recent Level Set description of the geometry and the novel eXtended Finite Element Method (XFEM). The method takes benefit of the fixed mesh work using X-FEM and of the curves smoothness of the Level Set description. Design variables are shape parameters of basic geometric features. The number of design variables of this formulation is small whereas various global and local constraints can be considered. The Level Set description allows to modify the connectivity of the structure as geometric features can merge or separate from each other. However no new entity can be introduced. A central problem that is investigated here is the sensitivity analysis and the way it can be carried out efficiently. Numerical applications revisit the classical elliptical hole benchmark from shape optimization. [less ▲]

INTA Cautelar. El gen completo que codifica para la proteína mayoritaria de la cápside del Virus de la leucosis bovina (BLV), p24, fue amplificado y clonado en un vector de expresión para E.coli. La proteína p24 recombinante (p24r) expresada fue caracterizada por Western blot utilizando un suero monoclonal y un suero policlonal de referencia, demostrando ser altamente específica y no reconocida por sueros de animales no infectados. La proteína fusionada a un tag de histidina fue purificada y utilizada como antígeno de ELISA para detectar anticuerpos anti-BLV en muestras individuales de suero bovino. La metodología fue optimizada en sus diferentes parámetros de uso como solución bloqueante, temperatura y tiempo de incubación, dilución de suero, fase sólida y sustrato colorimétrico; y se desarrolló a partir de estos resultados un ensayo de ELISA indirecto (ELISAp24r) que fue comparado con la prueba oficial de Inmunodifusión en gel de agar (IDGA) y un ELISA indirecto previamente validado, que utilizan como antígeno BLV completo semi-purificado obtenido de un cultivo celular persistentemente infectado. El ensayo comparativo demostró que de 91 sueros positivos por IDGA, 87 resultaron positivos por ELISAp24r. Asimismo, de un total de 184 sueros negativos por IDGA, 179 resultaron negativos por ELISA recombinante. El análisis comparativo mostró un índice de concordancia muy bueno con la prueba oficial de uso actual (IDGA). El ELISAp24r demostró ser una herramienta útil y fácil de aplicar para el diagnóstico de BLV sobre un gran número de muestras, y además posee una ventaja comparativa económica debido al bajo costo de producción y purificación del antígeno p24r en comparación con la producción del mismo a partir de cultivos celulares.

One of the main interesting concerns in work about numeration systems is studying the relationship that exist between arithmetic properties of numbers and syntactical properties of their representation. More precisely, we prefer to manipulate set of numbers whose representations are characterized by very simple syntactical rules, that is, forming a regular language. Such sets are called S-recognizable sets, where S is the numeration system we are working with. In particular, we would like to obtain numeration systems in which the whole set N is recognizable, partly due to the fact that, if the set of representations of all integers is regular, there are very simple algorithms making it possible to decide if a word stands or does not stand for a number. Some general questions in this area are the following. • Characterization of the recognizable parts in a fixed numeration system. • Determination of the numeration systems for which a given set of numbers is recognizable. • To examine the stability of recognizability under arithmetic operations. In this poster we present our research about that last problem. First, we will define the abstract numeration systems based on a regular language. Then we will study the relationship between multiplication by a constant and the S-recognizability for languages of the type a_1^∗ . . . a_k^∗. [less ▲]

Ultraviolet (UV) lines from Saturn's aurorae are emitted following inelastic collisions between energetic electrons and H[SUB]2[/SUB] molecules. De-excitation by radiative process lead to Far Ultraviolet (FUV) and Extreme Ultraviolet (EUV) emissions in the 750-1750 Å spectral window. Low resolution spectra ( 12 Å) obtained with HST/STIS in the 900-1700 Å window are employed to derive the absorption of the auroral photons by hydrocarbons (mainly methane) and depth of the auroral energy deposition. Determination of H[SUB]2[/SUB] temperature and overlying H[SUB]2[/SUB] column is achieved by analyzing spectra obtained with the FUSE instrument ( 0.2 Å resolution with the LWRS aperture in the 900-1200 Å spectral window). Below 1100 Å, transitions connecting to the v" = 0 and 1 levels of ground-state H[SUB]2[/SUB] are partially or totally absorbed by ambient H[SUB]2[/SUB] (self-absorption). Comparisons between observed and synthetic spectra allow to derive the gaz temperature and the overlying H[SUB]2[/SUB] column, which is an indicator of the depth of the aurora, hence of the energy of the precipitated electrons. Auroral spectra of Saturn at 12 Å resolution were also obtained with Cassini's Ultraviolet Imaging Spectrograph (UVIS), both in the EUV and FUV spectral bands. While the spectral resolution of UVIS is too low to estimate temperatures, the coverage of the entire UV domain allows to determine the energy of precipitated particles through the quantification of the methane and molecular hydrogen columns. Results from observations with these three instruments are presented and compared in order to characterize the auroral atmosphere and auroral electrons precipitated from Saturn's magnetosphere.

The aim of this work was to study the ability of two different strains of the yeast Yarrowia lipolytica to grow on Olive Mill Wastewater (OMW) and their potential to produce high-value products such as lipases. Factors affecting cellular growth and OMW degradation were studied, such as nitrogen supplementation, cells concentration and surfactant addition. Both strains used were able to grow in an OMW with a COD of 19 g/L and total phenols concentration of around 800 mg/L. The strain W29 presented the highest potential for extracellular lipase production from OMW. Lipase productivity was improved by the medium supplementation with ammonium sulphate up to 6 g/L, leading to 80 % of COD degradation and 70 % of total phenols reduction. The surfactant Tween 80 enhanced cell growth and COD degradation, but had no significant effect on lipase productivity. The results evidenced that the conditions that favoured lipase production differ from the conditions that improve COD removal from OMW. [less ▲]

Colloque - Répondre à la question de la conciliation des intérêts économiques et sociaux dans les centres d’appels ne peut se faire sans prendre en considération l’extrême hétérogénéité du secteur et des entreprises qui le composent. Souvent dénoncé pour la dégradation des conditions d’emploi et de travail qu’il entraîne, ce secteur d’activité est pourtant loin de répondre à une seule et même logique dans la gestion de l’emploi. Des études de cas diversifiées selon deux axes, le niveau de valeur ajoutée des services offerts par le centre d’appels, et sa complexité organisationnelle, laissent émerger des logiques différentes, influencées par la position de l’entreprise étudiée sur ces deux axes. Elles montrent l’existence d’un lien entre la configuration prise par la relation d’affaires qui unit le centre d’appels à ses clients ou donneurs d’ordres, et la politique interne de gestion de l’emploi. Ce lien n’est pas sans effet sur l’extrême difficulté à concilier les intérêts des travailleurs avec ceux des clients, particulièrement lorsque ces derniers interviennent lourdement dans la gestion interne du centre d’appels, ou en conditionnent fortement le fonctionnement par des exigences contractuelles.

Have you ever wondered what is the shortest route to join the office? What is the best way to plan a trip through several cities? You have maybe already played with magical squares? Then you have met one of the nu- merous instances of discrete optimization. Discrete optimization is a field of mathematics which deals with any problem where parts of the solutions cannot be divided or fractional. And as one may guess, this is the case in many real-life problems. This poster is divided in three main topics. The first part focuses on formulating those problems. We will start from one of the industrial appli- cations and show how we can model it as a mathematical problem. In the second part we sketch the main tools and algorithms used to tackle those problems. In particular we point out the fact that requiring integrality leads to extremely hard problems to solve. We show that despite this fact, we are able to solve problems of substantial size. However there remain some problems that are hard to solve using the state-of-the-art techniques. In the third part we indicate what are the chal- lenges of the field. In particular we will give an overview of the research car- ried out in the universities supported by the Marie-Curie network ADONET. [less ▲]

In order to investigate the influence of the nozzle capacity on the performance of fuel oil boilers, tests have been performed in transient and steady state regimes on our experimental boiler. The aim of the tests was to deduce the better couple nozzle - fuel injection pressure to reach the desired output power while producing fewer pollutants as possible. In short, a high fuel injection pressure associated with a low capacity nozzle is recommended. [less ▲]

Non-forward elastic hadron-scattering data are collected and analysed within the Regge approach. Through an analysis of the data in small bins in t, we have directly extracted the pomeron trajectory and the hadronic form factors (or reggeon couplings). We found higher values than usually used for the intercept and for the slope of the soft pomeron trajectory. The presence of zeros in t for the effective hadronic form factors is emphasised.

The object of the present paper is to present a fast and reliable CFD tool that is able to simulate stationary and transient operations of multistage axial compressors. The computational domain is the compressor flow path, using a row-by-row, quasi-one-dimensional representation of the machine at mid-span. This analysis tool is based on an adapted version of the Euler equations solved by a time-marching, finite-volume method. The basic Euler equations have been extended by including source terms expressing the blade-flow interactions. The source terms are determined using the velocity triangles for each blade row, at mid-span. The losses and deviations undergone by the fluid in each blade row are supplied by correlations. The resulting flow solver is a performance prediction tool based only on compressor geometry. It offers the possibility of exploring the entire characteristic map of a compressor before its construction. Its efficiency in terms of CPU time makes it possible to use it as a fast design tool by coupling it to an optimization algorithm. In this paper, this CFD tool (called Quads hereafter) has been applied to two test-cases. Calculated characteristic curves are presented and compared to experimental ones. A correlation tuning process is described for an undocumented family of blade profiles. [less ▲]

The impact of unitarity is considered in different approaches to saturation in impact-parameter space. The energy and momentum-transfer dependence of the total and differential cross sections and of the ratio of the real to imaginary parts of the scattering amplitude are obtained in a model that includes soft and hard pomeron contributions, coupled to hadrons via the electromagnetic form factor. It is shown that the hard pomeron may significantly contribute to soft physics at the LHC. A similar conclusion can also be reached in the framework of non-linear approaches to unitarisation of the BFKL pomeron. [less ▲]

The dynamic response of a mass-spring model of electrostatically actuated MEMS is analyzed when a voltage step is applied. The dynamics of a clamped-clamped beam representing a micro-bridge system are also considered. To model and simulate the strong coupling between the electric and mechanical fields, a general finite element program has been developed based on a new monolithic formulation. The methodology proposed in this program does not require any iterative numerical scheme based on separate electrostatic and mechanical solvers, respectively. [less ▲]
