Discontinuous Galerkin approximation of two-phase flows in heterogeneous porous media with discontinuous capillary pressures
No full textWe design and investigate a sequential discontinuous Galerkin method to approximate two-phase immiscible incompressible flows in heterogeneous porous media with discontinuous capillary pressures. The nonlinear interface conditions are enforced weakly through an adequate design of the penalties on interelement jumps of the pressure and the saturation. An accurate reconstruction of the total velocity is considered in the Raviart-Thomas(-Nedelec) finite element spaces, together with diffusivity-dependent weighted averages to cope with degeneracies in the saturation equation and with media heterogeneities. The proposed method is assessed on one-dimensional test cases exhibiting rough solutions, degeneracies, and capillary barriers. Stable and accurate solutions are obtained without limiters.

Swedish design in MoMA´s collection : a study of the collections correlations with the marketing of Swedish design in the U.S.A. 1930-1960
No full textMuseum of Modern Art har varit mycket tongivande för historieskrivningen och definitionen av modernismen, "the international style". Svensk modernisms mest kärnfulla period 1930-1960, representeras av 55 objekt i MoMAs arkitektur och designsamling. De svenska objekten i samlingen visar på en reception av svensk design som mest inflytelserik under 1950-talet. Årtiondet är det mest välrepresenterade, till antalet objekt räknade, men ger också den mest representativa bilden av hur svensk design marknadsfördes i USA. De mest inflytelserika tillfällena för marknadsföringen av svensk design i USA under åren 1930-1960 är enligt konstprofessor Jeff Werner (Medelvägens estetik: Sverigebilder i USA), världsutställningen i Chicago 1933, världsutställningen i New York 1939 och utställningen Design in Scandinavia 1954-1957. Knappt hälften av de representerade formgivarna i MoMAs samling fanns med under marknadsföringen ,vilket kan visa på samband mellan marknadsföringen och samlingens karaktär.Museum of Modern Art has been very influential for the historiography and definition of modernism, "the international style". Swedish modernisms most vigorous period 1930-1960, is represented by 55 items in MoMA´s Architecture and Design collection. The Swedish objects in the collection show at a reception of Swedish design as most influential during the 1950s. The decade is the most well-represented, in number of objects counted, but also gives the most representative picture of how Swedish design was marketed in the United States. The most influential opportunities for the promotion of Swedish design in the United States during the years 1930-1960 are according to art professor Jeff Werner (Medelvägens estetik: Sverigebilder i USA), the World's Fair in Chicago in 1933, the World's Fair in New York in 1939, and Exhibition Design in Scandinavia 1954-1957. Just under half of the represented designers in the MoMA collection, were included in the marketing, which can show correlations between marketing and the collection's character

No full textAllergic sensitization over the first eight years of life, associated factors and morbidity in PARIS birth cohort
No full textContexte. Les premières années de vie apparaissent particulièrement propices au développement de la sensibilisation allergénique. Objectifs. Cette thèse vise à : i) décrire les profils de sensibilisation allergénique chez le nourrisson et l’enfant, ii) étudier l’association entre ces profils et la morbidité allergique et iii) identifier les facteurs de risque de cette sensibilisation. Méthodes. Dans le cadre du suivi de la cohorte prospective de naissances en population générale Pollution and Asthma Risk: an Infant Study (PARIS), la sensibilisation allergénique a été évaluée chez 1 860 nourrissons à 18 mois et 1 007 enfants à 8/9 ans par dosage des IgE spécifiques dirigées contre 16 et 19 allergènes, respectivement. Les informations concernant la santé et le cadre de vie des enfants ont été recueillies par questionnaires standardisés répétés. Des profils de sensibilisation et des profils de morbidité ont été identifiés par classification non supervisée et mis en relation par régression logistique multinomiale. Enfin, les facteurs associés à la sensibilisation allergénique chez le nourrisson ont été étudiés par régression logistique multivariée. Résultats. Dès 18 mois, 13,8% des enfants étaient sensibilisés et 6,2%, multi-sensibilisés. À 8/9 ans, ces prévalences étaient de 34,5% et 19,8%, respectivement. Les profils de sensibilisation identifiés chez le nourrisson (3) et dans l’enfance (5) différaient au regard de la morbidité allergique. L’analyse étiologique a permis de préciser le rôle des expositions précoces aux allergènes et aux microorganismes sur la sensibilisation allergénique. Conclusion. Cette thèse contribue à une meilleure compréhension de l’histoire naturelle de la sensibilisation allergénique, et ce, dès les premières années de vie. Cette connaissance est essentielle à la prévention des maladies allergiques qui en découlent.Background. The first years of life appear to be critical for the development of allergic sensitization. Objectives. This thesis aims: i) to describe allergic sensitization profiles in infants and children, ii) to assess the link between these sensitization profiles and allergic morbidity, and iii) to identify risk factors for allergic sensitization. Methods. This work concerns children involved in the Pollution and Asthma Risk: an Infant Study (PARIS) population-based prospective birth cohort. Allergic sensitization was assessed in 1,860 18-month-old infants and 1,007 8/9-year-old children by specific IgE measurements towards 16 and 19 allergens, respectively. Lifelong health and living condition data were collected by repeated standardized questionnaires. Sensitization profiles and morbidity profiles were identified using unsupervised classification, and related to each other by multinomial logistic regression. Finally, risk factors for early allergic sensitization were assessed by multivariate logistic regression. Results. As soon as 18 months of age, 13.8% of children were sensitized and 6.2%, multi-sensitized. When 8/9 years old, corresponding prevalence was 34.5% and 19.8%, respectively. Sensitization profiles identified in infancy (3) and in childhood (5) differed in terms of allergic morbidity. Risk factor analysis allowed to clarify the role of early exposure to allergens and microorganisms on allergic sensitization. Conclusion. This thesis improves the natural history of allergic sensitization understanding, as soon as the first years of life. This knowledge is essential for subsequent disease preventing
