Assessing the Cost of Mounting an Immune Response
2003
International audience; The evolution of parasite resistance has often been assumed to be governed by antagonistic selection pressures. Defense against pathogens, by mounting an immune response, confers evident benefits but may also incur costs, so that the optimal level of defense is expected to depend on the balance between benefits and costs. Although the benefits of immune surveillance are well known, estimates of costs are still equivocal. Here we studied the behavioral and physiological modifications associated with exposure to a onreplicating antigen (lipopolysaccharide [LPS] of Escherichia coli) in a passerine species, the house sparrow (Passer domesticus).We further investigated wh…
Le dialogue de la musique et de la langue dans « Moderato cantabile » de Marguerite Duras
2014
Music in Duras’s works – analysed primarily in terms of intertextuality – is an element that creates the structure and sets the pace of the text. It provides an excuse to present feelings and thoughts of the characters, their hidden desires and yearnings. Music soothes the pain of parting, lets listeners forget about their problems, and brings forward true passions that cannot be put into words. Duras’s fondness of music is manifested by her attitude to reality and her vision of love. A piece of music with its depth and richness in a way reflects the inner self of the author.
Discussing Tourism as a Rite of Passage
2018
This chapter recapitulates the discussion originated by John Tribe respecting to the dispersion of produced knowledge in tourism. We critically give a new fresh paradigm in order for readers to understand what tourism is. This chapter centers on themes I am not accustomed to discuss but are very important to the epistemological advance of the discipline, precisely in a moment where the epistemology of tourism enters in a serious crisis. Though I here am synthesizing my experience as author, reviewer and editor, no less true is that it situates as a complementary platform to expand the current understanding of tourism and its intersection in culture.
Écrire sans honte: la sexualité féminine en question dans les traductions anglo-américaines de Passion simple, L’Événement et L’Occupation d’Annie Er…
2011
Cet article prend le parti d’étudier le rendu du discours sur la sexualité dans Passion simple et L’Occupation et celui sur la procréation dans L’Événement dans les traductions anglo-américaines de ces trois textes. Annie Ernaux conçoit l’écriture comme une activité politique destinée, entre autres tâches, à dénoncer la domination masculine. Ce travail passe par l’inscription textuelle de la sexualité et de la corporalité féminines. Il s’agit en effet pour l’auteure de s’approprier la liberté d’écrire « sans honte » et de transgresser une loi du silence imposée par la société. L’effort d’objectivation qui caractérise l’écriture ernausienne s’appuie sur un style dépourvu de métaphores et mar…
La mesura de l'ús de les llengües en els mitjans telemàtics
2020
La consolidació de l'entorn digital i totes les seues modalitats de comunicació ha ampliat les possibilitats d'interacció i, per tant, els àmbits d'ús de les llengües. Com a adaptació a aquesta nova realitat, en aquesta aproximació metodològica plantegem la combinació de diferents tècniques no reactives: explotació de fonts secundàries, observació sistemàtica, i mystery shopping. Les fonts d'observació directa ens permeten mesurar de manera efectiva l'ús de les llengües en la comunicació telemàtica. Els autors ho han aplicat específicament en l'administració local i en empreses de serveis. En l'àmbit administratiu, a més, això ens ha servit per a desenvolupar un índex global de presència de…
Polyphased mesozoic rifting from the Atlas to the north-west Africa paleomargin
2021
24 pages; International audience; Based on the interpretation of geological maps, seismic reflection and well data complemented with a bibliographic compilation and field work in the Rif, we investigate the factors that control the rift initiation, its development and the formation of oceanic crust in NW Africa. From SE to NW, we examine the Western Sahara Atlas, the Tendrara, the Guercif, and the Rif basins, to establish their geodynamic evolution in relation with the Mesozoic formation of the Central Atlantic and Maghrebian Tethys oceans, respectively. The Triassic extension was diffuse and developed over Lower Carboniferous horst-and-graben structures formed in the NW passive margin of G…
Perceived Competence in the Face of Death before and after Nursing Studies: An Intrasubject Longitudinal Study
2021
Perceived competence is a subject’s perception of being able to interact effectively with the environment. Perceived Competence in the face of death in Nursing degree programs in which the presence of the subject of death and bereavement is key becomes more topical and relevant. The objective of this study is to determine whether this competence is improved through Nursing Studies. This study was designed as paired repeated intrasubject measures, initial measurement at the beginning of the first year and second measurement in the fourth year of the Nursing degree. One hundred and seventeen nursing students were assessed. Significant improvement is evidenced in three of the four dimensions o…
Advanced Analysis of Propagation Losses in Rectangular Waveguide Structures Using Perturbation of Boundary Conditions
2011
In this paper, propagation losses effects present in rectangular waveguide structures are rigorously considered. For this purpose, a new formulation based on the perturbation of the boundary conditions on the metallic walls of the waveguides combined with an Integral-Equation (IE) analysis technique is proposed. Following this advanced technique, the drawbacks of the classical power-loss method are overcome and a complex modal propagation constant is computed. To validate this theory, we have successfully compared our results with numerical data of lossy hollow waveguides. Next, a Computed-Aided-Design (CAD) software package based on such a novel modal analysis tool has been used to predict…
Predicting the bioaccumulation of polyaromatic hydrocarbons and polychlorinated biphenyls in benthic animals in sediments
2016
There were two main objectives in this study. The first was to compare the accuracy of different prediction methods for the chemical concentrations of polyaromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) in the organism, based on the measured chemical concentrations existing in sediment dry matter or pore water. The predicted tissue concentrations were compared to the measured ones after 28-day laboratory test using oligochaeta worms (Lumbriculus variegatus). The second objective was to compare the bioaccumulation of PAHs and PCBs in the laboratory test with the in situ bioaccumulation of these compounds. Using the traditional organic carbon-water partitioning model, tissue…
Robust reliable passive control of uncertain stochastic switched time-delay systems
2014
This paper investigates the problem of robust reliable passive control for a class of uncertain stochastic switched time-delay systems with actuator failures. The multiple Lyapunov functions (MLFs) technique is exploited to derive a delay-dependent sufficient condition for the stochastic switched time-delay systems to be passive and exponentially stable under a state-based switching law. Moreover, the proposed approach is extended to investigate stochastic switched systems with structured uncertainties. Finally, two numerical examples are presented to illustrate the effectiveness of the proposed method.
