Notre thèse se décline en une approche chronologico-thématique autour de trois pôles majeurs. Il s'agit, tout d'abord d'une démonstration qui entend établir un tableau aussi précis que possible de la structure, des rouages et de l'implantation des organisations d'AF à Paris et en province. L'objectif est ensuite d'analyser les grandes matrices de l'engagement militant mais aussi et surtout leurs évolutions successives en lien avec un contexte politico-diplomatique extrêmement mouvant. Il s'agit pour chaque période donnée de chercher à comprendre ce qui constitue l'engagement au sein de la ligue dans une approche résolument tournée vers la base militante. Enfin, il faut réfléchir à la place et au rôle de l'AF dans la nébuleuse royaliste et nationaliste de son temps afin de comprendre les jeux d'alliance et de concurrence entre les diverses organisations mais aussi dans quelle mesure et de quelle manière la ligue d'AF s'est intégrée au répertoire d'action collective de son temps tout en participant à son renouvellement. Le choix de notre découpage chronologique répond à des nécessités à la fois contextuelles et propres à l'histoire de l'Action française. Au cours de la première période, de 1905 à 1914, on assiste à une structuration rapide et continue de l'appareil d'action intellectuelle et militante. Les rouages nationaux et locaux de la ligue se mettent en place et les matrices de l'engagement militant sont diffusées par l'intermédiaire du quotidien et contribuent à influencer l'opinion publique. A cette époque, l'AF est presque seule dans le champ nationaliste mais doit se positionner au sein du monde royaliste. Pendant la Grande Guerre, les structures de la ligue sont désorganisées. L'objectif principal est alors de continuer à diffuser le journal ce qui n'empêche pas la ligue d'utiliser le temps de guerre pour tenter de nouvelles méthodes de propagande notamment dans l'armée. La période 1914-1918 permet aussi à l'AF de se respectabiliser en choisissant la voie de l'Union sacrée. Elle reste malgré tout une organisation particulièrement surveillée d'autant plus que son influence dans l'opinion publique s'accroît. Après-guerre, l'AF se réorganise partout en province. Au cours de la période 1919-1926, elle fait l'expérience de la vie parlementaire et glisse, de fait, vers une sorte de conservatisme contre lequel elle s'est initialement constituée. Ses échecs électoraux couplés à l'influence croissante des communistes dans la vie publique contribuent à relancer son activisme militant mais pas suffisamment selon certains de ses membres qui suivent alors Georges Valois dans la dissidence du Faisceau. L'AF doit également faire face à l'apparition d'une nouvelle concurrence nationaliste avec la naissance des Jeunesses Patriotes. En 1926, elle est confrontée à la plus grave crise de son histoire : sa condamnation pontificale. Au cours de la période 1927-1929, la ligue cherche à rebondir et à maintenir son implantation et ses activités dans un contexte, par ailleurs, globalement défavorable. Les résultats sont extrêmement nuancés selon les régions mais, dans l'ensemble, il n'y a pas d'écroulement de sa structure militante même si les difficultés financières de la ligue sont de plus en plus importantes. Au tournant des années 1930, la crise économique aggrave encore ces difficultés mais contribue aussi à créer un contexte favorable à un nouvel épisode de flambée ligueuse. Au cours de la période 1933-1936, l'AF connaît un regain de vitalité dont le paroxysme se situe au moment du 6 février 1934. Cela étant, cet épisode démontre également les limites et les faiblesses du phénomène ligueur nationaliste en France. [less ▲]

Research on nuclear technologies has been largely driven by a detachment of the 'technical content' from the 'social context'. However, social studies of science and technology - also for the nuclear domain – emphasize that 'the social' and 'the technical' dimensions of technology development are inter-related and co-produced. In an effort to create links between nuclear research and innovation and society in mutually beneficial ways, the Belgian Nuclear Research Centre started fifteen years ago a ‘Programme of Integration of Social Aspects into nuclear research’ (PISA). In line with broader science-policy agendas (responsible research and innovation and technology assessment), this paper argues that the importance of such programmes is threefold. First, their multi-disciplinary basis and participatory character contribute to a better understanding of the interactions between science, technology and society, in general, and the complexity of nuclear technology assessment in particular. Second, their functioning as (self )critical policy supportive research with outreach to society is an essential prerequisite for policies aiming at generating societal trust in the context of controversial issues related to nuclear technologies and exposure to ionising radiation. Third, such programmes create an enriching dynamic in the organisation itself, stimulating collective learning and transdisciplinarity. The paper illustrates with concrete examples these claims and concludes by discussing some key challenges that researchers face while engaging in work of this kind. [less ▲]

Adult neural crest stem cells (NCSC) are of extraordinary high plasticity and promising candidates for a use in regenerative medicine. Several locations like skin, adipose tissue, dental pulp or bone marrow have been described in rodent. However, very few information is available concerning their correspondence in human tissues. The main objective of this study was therefore to characterize NCSC from adult human bone marrow. In this purpose, we compared human bone marrow stromal cells to human adipose tissue and dermis, already described for containing NCSC. We performed comparative analyses in terms of gene and protein expression, as well as functional characterizations. It appeared that human bone marrow, similarly to adipose tissue and dermis contains NESTIN+ / SOX9+ / TWIST+ / SLUG+ / P75NTR+ / BRN3A+/ MSI1+/ SNAIL1+ cells and were able to differentiate into melanocytes and Schwann cells. Moreover, when injected into chicken embryos, all those cells were able to migrate and follow endogenous neural crest migration pathways. Altogether, the phenotypic characterization and migration abilities strongly suggest the presence of neural crest-derived cells in human adult bone marrow. [less ▲]

A large number of UV images of Jupiter's aurora were obtained in 2007/2008 with the Hubble Space Telescope (HST) ACS/SBC camera. The initial results on variations with the solar wind conditions have been published elsewhere, but the large database permits other studies to be performed. In particular, while auroral emissions have been detected from the magnetic footprints of Io, Europa, and Ganymede in Jupiter's atmosphere, the footprint of Callisto has been located too close to the main auroral oval to be detected. We have thus analyzed images of the ultraviolet auroral emissions of Jupiter taken using the F115LP filter on the HST/ACS instrument. Using a unique co-addition method, we have identified a strong candidate for the footprint of Callisto on May 24, 2007. We tested this finding by applying the same co-addition method to a nearly identical auroral configuration on May 30, 2007 when Callisto was well removed in its orbit. Comparing the two co-added images, we can clearly see the presence of Callisto’s footprint on the 24th and its absence on the 30th. The method relies as well on the motion of Callisto's footprint remaining under the satellite, while most of the auroral emissions rotate with the planet. The images and analysis method will be presented in this presentation. [less ▲]

Ces dernières années, l’historiographie des premières Guerres d’Italie (1494-1525) s’est considérablement enrichie notamment grâce aux études de D. Le Fur, N. Hochner, A.-M. Lecoq et R. W. Scheller. Croisant délibérément des sources variées (littéraires, politiques et iconographiques) ainsi que les méthodes (celle de l’historien des textes et celle de l’historien d’art), leurs travaux se sont attachés à définir les différents aspects du pouvoir royal et la manière dont celui-ci se met en scène tout spécialement sous les règnes de Charles VIII, de Louis XII et de François Ier. Force est donc de constater que la figure du roi de France domine l’historiographie récente des premières Guerres d’Italie. Pourtant, à chaque fois que les souverains des fleurs de lys sont mis en scène, ils n’occupent pas seuls le discours politique. D’autres personnages, la France et les Français, apparaissent à côté d’eux. Le premier est dépeint, selon une tradition établie, comme un espace bénéficiant de qualités exceptionnelles. Lesdites qualités conditionnent la nature du deuxième personnage – les Français –, lequel s’intègre dès lors à un portrait de la nation. Durant les Guerres d’Italie, ce discours sur la France et les Français ne sert pas uniquement à décrire le royaume lui-même. Il permet avant tout aux artisans de la propagande royale d’élaborer une pensée légitimant la conquête de l’Italie et permettant d’y imposer une nouvelle culture politique et sociale d’inspiration française. Cet amalgame d’images à propos de l’Italie française ou Franco-Italia traverse l’ensemble de la période, croisant parfois la figure royale, mais s’en éloignant aussi très souvent. L’étude d’une telle idéologie révèle enfin un intérêt supplémentaire. Au cours des premières décennies du XVIe siècle, la France connaît un véritable bouleversement de son modèle d’organisation sociale traditionnel. Nous voulons parler des trois ordres du féodalisme (oratores, bellatores et laboratores). Certes, dans la réalité quotidienne, le système ternaire ne reflète plus, depuis des siècles, la complexité des relations politiques et sociales. Par contre, la remise en cause de ce modèle au sein de la pensée politique curiale, en somme dans la culture de l’élite, est une donnée relativement nouvelle en ce début de XVIe siècle. Ainsi, le discours sur l’Italie française sert de champ d’expérimentation aux théoriciens du politique, aux polémistes ainsi qu’aux chroniqueurs et même aux poètes, leur permettant de redéfinir les contours d’un schéma ternaire qui, dans sa forme traditionnelle, leur apparaît désuet. On l’aura compris : notre thèse s’oriente donc vers l’étude, non d’un seul mode de pensée, mais plutôt d’une pluralité de concepts et d’opinions ayant comme dénominateur commun la redéfinition des contours de l’Italie et également de la France. Il s’agira de comprendre la manière dont les auteurs de la cour de France regardent la Péninsule et ses habitants et comment, de cette expérience de l’altérité, ils en arrivent à pratiquer un retour sur eux-mêmes et à relire leur propre mode d’organisation sociale, autrement dit, les cadres théoriques de leur existence. Cette histoire des lys qui s’évertuent à fleurir dans les champs d’une Italie pourtant bien décidée à les faucher sera l’occasion d’entrevoir sous un angle neuf cette période de bouleversements et d’inquiétudes que sont les premières Guerres d’Italie.

During the first Italian Wars (1494–1525), at the court of France, an ideology of assimilation of Italy by France is developing: Franco-Italia. Historiographers and poets show the Peninsula as a new France populated by Italians Frenchified. But this thought reveals much more than an attempt absorption of Italy by France. It highlights a real disruption of traditional social structures. At the beginning of the sixteenth century, there is a critique of the social order at the heart of the closed circles of power. This work is well under the sign of acculturation - that of Italy and Italians - and reflection of identity - Frenchising Italy, the French redefine their own socio-political structures. It enlights the very nature of political thought at the beginning of the Renaissance, thought full of contradictions and doubts, in a period full of turmoil and worry. [less ▲]

Ces derniers ont pour objectif de faire avancer les relations économiques, commerciales, politiques, culturelles et de coopération. Toutefois, le sommet de Lima a démontré l'écart entre les intentions de créer un "partenariat stratégique" et la réalité qui est traversée par des conflits aussi bien entre l'UE et l'AL qu'au sein même des relations intralatinoaméricaines. Cette situation bloque les ambitions de l'agenda UE/AL. [less ▲]

The Imaging Ultraviolet Spectrograph (IUVS) on NASA's Mars Atmosphere and Volatile Evolution (MAVEN) mission observed the Martian upper atmosphere in late 2015 (Ls ~ 70) and early 2016 (Ls ~ 150). Although designed to measure the dayglow between 90-200 km IUVS also scans the limb down to 60 km, where solar scattered light dominates the mid-ultraviolet (MUV) signal. Occasionally, this MUV light shows enhanced scattering between 60-90 km indicating the presence of aerosols in the mesosphere. We quantify the solar scattering for each daylight scan obtained between October and December, 2015 and between April and June, 2016. We then identify over 100 scans of enhanced scattering between 60-90 km and assemble them both geographically and diurnally. The geographical distribution of the enhancements in 2015 is preferentially located near the equator, consistent with previous observations of mesospheric clouds for this part of the season. A wave three pattern in equatorial cloud occurrence suggests forcing from a non-migrating tide, possibly linked to the longitudinal variation of Mars surface topography. At the same time, there are indications of a diurnal variation such that the clouds seen in 2015 and 2016 are preferentially observed in the early morning, between 0600-0900 local solar time. This suggests an important role for a migrating temperature tide controlling the formation of Martian mesospheric clouds. [less ▲]

Limb observations of the spectrum of nightglow emission in the delta (190-240 nm) and gamma (225-270 nm) bands of nitric oxide have been made with the Spectroscopy for Investigation of Characteristics of the Atmosphere of Venus (SPICAV) ultraviolet spectrometer on board Venus Express. These emissions arise from radiative recombination between O([SUP]3[/SUP]P) and N([SUP]4[/SUP]S) atoms that are produced on the dayside and recombine to form excited NO molecules on the nightside. No other emission feature has been identified. The mean altitude of the emission layer is located at 113 km, but it varies between 95 and 132 km. The mean brightness of the total NO emission at the limb is 32 kR, but it is highly variable with limb intensities as large as 440 kR observed at low latitude and values below 5 kR seen at northern midlatitudes. No systematic dependence of the brightness with latitude is observed, but the mean altitude of the emission maximum statistically drops with increasing latitude between 6° and 72°N. Typical observed limb profiles are compared with simulations based on a one-dimensional chemical-diffusive atmospheric model. From model fits to observed profiles, we find that the downward flux of N atoms at 130 km typically varies between 1 × 10[SUP]8[/SUP] to 4 × 10[SUP]9[/SUP] atoms cm[SUP]-2[/SUP] s[SUP]-1[/SUP]. Comparisons of observed airglow topside scale heights with modeled profiles smoothed by the instrumental field of view indicate that the observations are compatible with a downward flow of O and N atoms by molecular and turbulent transport above the peak of emission. The K coefficient deduced from comparisons to limb profiles is less than that determined from the observations made with the Pioneer Venus UV spectrometer at low latitude during periods of high solar activity.

Objective: To investigate functional connectivity between the default mode network (DMN) and other networks in disorders of consciousness. Methods: We analyzedMRI data from 11 patients in a vegetative state and 7 patients in a minimally conscious state along with age- And sex-matched healthy control subjects. MRI data analysis included nonlinear spatial normalization to compensate for disease-related anatomical distortions. We studied brain connectivity data from resting-state MRI temporal series, combining noninferential (independent component analysis) and inferential (seed-based general linear model) methods. Results: In DMN hypoconnectivity conditions, a patient's DMN functional connectivity shifts and paradoxically increases in limbic structures, including the orbitofrontal cortex, insula, hypothalamus, and the ventral tegmental area. Conclusions: Concurrently with DMN hypoconnectivity, we report limbic hyperconnectivity in patients in vegetative and minimally conscious states. This hyperconnectivity may reflect the persistent engagement of residual neural activity in self-reinforcing neural loops, which, in turn, could disrupt normal patterns of connectivity. [less ▲]

Limestone filler is a raw material that is already used in several applications like paints, bricks, bituminous mixtures…etc. Moreover, and particularly in Belgium, classical additions for concrete like fly ashes and granulated blast furnace slags are becoming rare; there is a need for new additions that could have a positive effect on the properties of the fresh and hardened cementitous composites. Substitution of limestone filler in Portland cement and Granulated blast furnace slag cement has been realized between 15 and 27 % in mass. In addition to the characterization of the powder itself – specific mass, specific surface and laser granulometry – the problem of the water demand has been analysed: it seems that it remains constant with the substitution rate. Electric conductivity has also been performed in order to study the evolution of the “dormant” period. Tests on hardened mortars were performed with regard to mechanical properties and evolution of the porosity. Test results indicate that the porosity seems to be finer in the case of granulated blast furnace slags cements, partially due to a very low diameter of the slags particles. Oxygen permeability doesn’t seem to be influenced by the filler while capillary absorption increases with substitution rate. Finally, carbonation rate, sulphate resistance and chloride penetration show quite interesting behaviours, leading to the conclusion that limestone fillers maybe a good substitution material.
