La personnalité borderline: clinique d'une psychopathologie "sans limites"

The borderline personality disorder is a common psychiatric entity, which is characterized by a varied symptomatology and a significant comorbidity. It seems that its etiologic is heterogeneous, comprising psychosocial factors as much as biological and genetic. So the best approach of the borderline personality disorder would be a multidisciplinary bio-psycho-social one. Through a clinical case, we illustrate this disorder and its treatment in outpatient clinic. [less ▲]

Development of Bio-climatic zones in North East India

This paper represents the very basic work of bio-climatic classification of north-east India into warm and humid, cool and humid and cold and cloudy zones. This classification is extremely useful to the building design for wide range of objectives such as climate responsive building design, building energy conservation, thermal comfort, out door design conditions, etc. This classification is based on the meteorological data collected over a period of more than 30 years, from Regional Meteorological Centre, Guwahati, India from 30 stations spread all over the region. Psychometric charts are prepared for each bio-climatic zone to assess the potential of solar passive design strategies for residential buildings. [less ▲]

Interaction between dendritic cells and nerve fibres in lymphoid organs after oral scrapie exposure

In transmissible spongiform encephalopathies (TSEs), the infectious agent, called PrPsc, an abnormal isoform of the cellular prion protein, accumulates and replicates in lymphoid organs before affecting the nervous system. To clarify the cellular requirements for the neuro-invasion of the scrapie agent from the lymphoid organs to the central nervous system, we have studied, by confocal microscopy, the innervations within Peyer's patches, mesenteric lymph nodes and the spleen of mice in physiological conditions and after oral exposure to prion. Contacts between nerve fibres and PrPsc-associated cells, dendritic cells (DCs) and follicular dendritic cells (FDCs), were evaluated in preclinical prion-infected mice. Using a double immunolabelling strategy, we demonstrated the lack of innervation of PrPsc-accumulating cells (FDCs). Contacts between nerve fibers and PrPsc-propagating cells (DCs) were detected in T-cell zones and cell-trafficking areas. This supports, for the first time, the possible implication of dendritic cells in the prion neuroinvasion process. [less ▲]

En Belgique, la Fondation Roi Baudouin est une référence en matière de développement du bien-être des citoyens. Depuis très longtemps, elle est aussi un des piliers belges en matière du développement d'activités utilisant les vertus sociales du sport et son rôle pour le bien-être de la population. L'Université de Liège a été chargée de réaliser une étude prospective visant à identifier des pistes d'interventions originales susceptibles de rencontrer les besoins actuels des acteurs de terrain dans le domaine du "sport social" et de stimuler le développement de ce dernier en Communauté Wallonie-Bruxelles. La première étape a porté sur l'établissement d'un état des lieux non exhaustif des initiatives utilisant le sport 'activité physique en général) comme outil social. Sur base des informations fournies par les acteurs de terrain, il était aussi question d'identifier les raisons justifiant le développement limité des nitiatives locales ou régionales dans ce secteur d'activité et les moyens qui devraient être mis en oeuvre pour remédier à cette situation. Dans une deuxième étape, un groupe de praticiens s'est réuni en vue de faire émerger les pistes d'actions dans lesquelles la Fondation Roi Baudouin pourrait s'investir afin de rencontrer les attentes réelles des citoyens. Des propositions concrètes ont ainsi pu être formulées. Elles peuvent être considérées comme des recommandations ou, mieux encore, comme une source d'inspiration. ... [less ▲]

Aims:The principal aim of this project is to determine the structural parameters of the rapidly pulsating subdwarf B star PG 0911+456 from asteroseismology. Our work forms part of an ongoing programme to constrain the internal characteristics of hot B subdwarfs with the long-term goal of differentiating between the various formation scenarios proposed for these objects. So far, a detailed asteroseismic interpretation has been carried out for 6 such pulsators, with apparent success. First comparisons with evolutionary theory look promising, however it is clear that more targets are needed for meaningful statistics to be derived. Methods: The observational pulsation periods of PG 0911+456 were extracted from rapid time-series photometry using standard Fourier analysis techniques. Supplemented by spectroscopic estimates of the star's mean atmospheric parameters, they were used as a basis for the “forward modelling” approach in asteroseismology. The latter culminates in the identification of one or more “optimal” models that can accurately reproduce the observed period spectrum. This naturally leads to an identification of the oscillations detected in terms of degree ℓ and radial order k, and infers the structural parameters of the target. Results: The high S/N low- and medium resolution spectroscopy obtained led to a refinement of the atmospheric parameters for PG 0911+456, the derived values being T_eff = 31 940 ± 220 K, log g = 5.767 ± 0.029, and log He/H = -2.548 ± 0.058. From the photometry it was possible to extract 7 independent pulsation periods in the 150-200 s range with amplitudes between 0.05 and 0.8% of the star's mean brightness. There was no indication of fine frequency splitting over the 68-day time baseline, suggesting a very slow rotation rate. An asteroseismic search of parameter space identified several models that matched the observed properties of PG 0911+456 well, one of which was isolated as the “optimal” model on the basis of spectroscopic and mode identification considerations. All the observed pulsations are identified with low-order acoustic modes with degree indices ℓ = 0,1,2 and 4, and match the computed periods with a dispersion of only 0.26%, typical of the asteroseismological studies carried out to date for this type of star. The inferred structural parameters of PG 0911+456 are T_eff = 31 940 ± 220 K (from spectroscopy), log {g} = 5.777 ± 0.002, Mast/Msun = 0.39 ± 0.01, log{M_env/Mast} = -4.69 ± 0.07, R/Rsun = 0.133 ± 0.001 and L/Lsun = 16.4 ± 0.8. We also derive the absolute magnitude MV = 4.82 ± 0.04 and a distance d = 930.3 ± 27.4 pc. [less ▲]

We explore collective behavior in biological systems using a cooperative control framework. In particular, we study a hysteresis phenomenon in which a collective switches from circular to parallel motion under slow variation of the neighborhood size in which individuals tend to align with one another. In the case that the neighborhood radius is less than the circular motion radius, both circular and parallel motion can occur. We provide Lyapunov-based analysis of bistability of circular and parallel motion in a closed-loop system of selfpropelled particles with coupled-oscillator dynamics. [less ▲]
