From the second half of the last century ecology has been recognized as one of the most important value in landscape design, together with aesthetics and social involvement (Ian H. Thompson). After a period dominated by the prevalence of the aesthetical values in landscape/gardens conception a new perspective arose: the global growth and the effects of exploitation of natural resources have generated an increasing awareness about the impacts of human life on environment and a reflection on new possible way of living balancing the quality of life and the respect for nature in our territories. The ecological approach has developed thanks to some landscape architects contributions, based on their researches on: the displacement from a more anthropocentric to a more ecocentric view in landscape planning (Ian McHarg) and the introduction of the principles of balance, diversity, sustainability in order to learn to perceive and to design healty landscapes. Working with nature, in landscape urbanism, means to activate processes involving plants, animals and people, with the aim of improving the quality of life in urban environment. Therefore ecology is strictly linked to aesthetical and social aspects: landscape design must relate spatial values, by reinterpreting and enhancing the characters of the places, with social values, by introducing activities to strengthen social interactions. In contemporary landscape design, ecology is interpreted as a key approach, concerning mostly regenerative design (J.T Lyle). This innovative concept considers design as the cultural instrument accompanying and orienting ecological processes. In fact landscape design deals with urban development strategies, interventions on urban fringes, reclamation of waste lands: in all cases arise the necessity to rethink the territories starting from the restoration of an interrupted balance between natural resources and anthropic actions. The ecological approach is based on the use of natural elements and dynamics as a means for transformation of the territories. One powerful effect of these interventions is the capacity to recover the relationship between people and the spirit of the places and sometimes, the possibility to build a new identity, especially in rejected areas, and this is a “catalyst act”, involving society in regenerative design programs. New green structures enhancing environmental qualities and protecting biodiversity, agricultural technologies remediating soils and water are only few of the potentials of landscape ecology. Another important consequence of this innovative approach is the rise of a new aesthetics, as “nature is perceived as a process, not as a scenary” (R.Smithson). Recognizing change and uncertainty as the basic dynamics of landscape (M.Antrop), designers methods and sensitivity appear more effective if based on predicting different and open scenarios. But ecology is not a panacea itself: the risks in ecosystem service approach are several. First, specially in public spaces design, there is the risk of confusing the primary values of the action of planting trees and greenery: some aesthetical choices could not represent the ecological efficiency. This happens very often because the client’s will is more oriented to achieve an immediate effect, where vegetation’s use is equated to a decorative device, instead of a new balance generator one. Similarly, choices based on low maintenance perspective are not always synonymous of ecology. Furthermore, in Urban Planning, prescriptions about greenery and trees plantation follow some quantitative parameters instead of qualitative ones. The contribution of landscape design to Urbanism is based on a multidisciplinary approach which tends to detect and enhance those hidden and overwritten features characterizing the “genius loci”. Thus, ecology represents a site specific aspect and its introduction in landscape urbanism supposes a deep knowledge of the process and its effects on environment and on society. [less ▲]

OBJECTIVES: To compare the concordance of ceftaroline MIC values by reference broth microdilution (BMD) and Etest (bioMérieux, France) for MSSA and MRSA isolates obtained from PREMIUM (D372SL00001), a European multicentre study. METHODS: Ceftaroline MICs were determined by reference BMD and by Etest for 1242 MSSA and MRSA isolates collected between February and May 2012 from adult patients with community-acquired pneumonia or complicated skin and soft tissue infections; tests were performed across six European laboratories. Selected isolates with ceftaroline resistance in broth (MIC >1 mg/L) were retested in three central laboratories to confirm their behaviour. RESULTS: Overall concordance between BMD and Etest was good, with >97% essential agreement and >95% categorical agreement. Nevertheless, 12 of the 26 MRSA isolates found resistant by BMD scored as susceptible by Etest, with MICs ≤1 mg/L, thus counting as very major errors, whereas only 5 of 380 MRSA isolates found ceftaroline susceptible in BMD were miscategorized as resistant by Etest. Twenty-one of the 26 isolates with MICs of 2 mg/L by BMD were then retested twice by each of three central laboratories: BMD MICs of 2 mg/L were consistently found for 19 of the 21 isolates. Among 147 Etest results for these 21 isolates (original plus six repeats per isolate) 112 were >1 mg/L. CONCLUSIONS: BMD and Etest have good overall agreement for ceftaroline against Staphylococcus aureus; nevertheless, reliable Etest-based discrimination of the minority of ceftaroline-resistant (MIC 2 mg/L) MRSA is extremely challenging, requiring careful reading of strips, ideally with duplicate testing.

Dans les années 1920 et 1930, Liège, qui fut aux premières loges de la Grande Guerre, doit d’abord panser ses plaies pour mieux poursuivre sa modernisation urbanistique. Entre francophilie et germanophobie, elle cherche à assumer son statut de métropole industrielle, de cité culturelle et de capitale du mouvement wallon. Si les Expositions de 1930 et 1939 la mettent en évidence, l’inquiétude face aux enjeux politiques et économiques n’est pas absente, d’autant qu’à l’Est gronde une nouvelle menace. [less ▲]

Les multiples systèmes, formes, catégories et pratiques de la parenté ont retenu l’attention des anthropologues comme une dimension centrale des façons dont les individus et les groupes humains conçoivent et vivent leurs rapports à eux-mêmes, aux autres, aux sociétés et au monde qui les entoure. Dans différents contextes et périodes historiques, des évolutions – tant démographiques, politiques, socio-culturelles, économiques, juridiques, scientifiques, médicales, ou encore relatives aux âges ou aux genres – ont contribué à sa (re)définition constante. Force est de constater que les innovations récentes concernant, entre autres, les technologies de procréation médicalement assistée et de gestation pour autrui, ou les débats autour du « mariage pour tous » et de l’adoption par des couples du même sexe, ont parfois été interprétés en termes de profondes ruptures par rapport à des conceptions plus « traditionnelles » de la parenté, ce qui leur confère un certain caractère inédit et polémique. D’un point de vue anthropologique, ces reconfigurations de la parenté témoignent de différentes modalités d’articulation entre le social, le culturel et le biologique, faits de société et faits de nature, construit et inné, dans la définition de la parenté. Cela amène à repenser la parenté dans toutes ses dimensions, du public à l’intime. Partant de l’anthropologie, et afin d’élargir le champ des réflexions empiriques, théoriques et épistémologiques, ce colloque invite à croiser les perspectives sur les (re)configurations contemporaines de la parenté dans les sciences humaines et sociales en privilégiant les approches ethnographiques. Il comprend deux axes principaux mais non exclusifs. Le premier axe entend appréhender les manières dont la question des (re)configurations contemporaines de la parenté est posée dans différents espaces publics et intimes. Le second axe ouvre quant à lui un débat épistémologique sur les regards croisés et comparatifs entre divers contextes, thématiques ou disciplines en invitant à analyser les enjeux, apports et limites issus de tels travaux de recherche.

Equol is a microbial metabolite of isoflavones that could be used as therapeutic agent against several diseases and cancers. Cow's milk could be a potential source of equol in the human diet, but more studies are needed on the changes in equol concentration during the technological processing of milk and dairy products. This first exploratory study sought to assess the impact of industrial skimming and microfiltration processes on equol concentration in conventional cow's milk. The milk samples used in this study came from bulk cow’s milk collected in Wallonia (Belgium), by a local dairy and processed in a local cheese factory. Six random sampling were conducted during spring and, for each of them, samples from raw, skimmed and microfiltered milk were analyzed. Equol was present in all samples at a concentration of between 3.2 and 10.3 µg.L-1. A Wilcoxon's signed rank test was then performed on the difference of data, having raw milk as reference, irrespective of the collection date. The results showed that the skimming process slightly increased the equol concentration in milk and therefore that equol had no or little affinity with the lipid milk fraction. The results also showed that, with the microfiltration process, a small proportion of equol was retained. Equol concentration has returned to the same level as that found in raw milk. This might be because of a chemical affinity either with bigger molecules that are physically retained or through direct interaction with the membrane. This scoping study paves the way for more extensive studies on the interaction between equol and other components of the milk. [less ▲]

Dans le champ intellectuel contemporain, la pensée de Paul Ricœur semble avoir pleinement intégré l’outillage conceptuel requis pour penser les identités et modes de subjectivation. Contre les conceptions du texte comme espace formel autorégulé, Ricœur a décrit le récit comme un dispositif cognitif fondamental, offrant aux individus et aux collectivités des modes de subjectivation et des prises sur le monde. Cette approche constitue un bénéfice disciplinaire non- négligeable pour les sciences humaines. Cette actualité de Ricœur peut sembler paradoxale. Certes, le concept de refiguration permet de penser les effets du récit dans le monde, à une époque où la diffusion massive d’information nécessite de capter l’attention par des récits efficaces (storytelling en politique, publicité, management, infotainment). Par contre, le concept d’identité narrative ne semble pas pouvoir se justifier de la même actualité. En effet, quoi de plus opposé à nos expériences démultipliées que cette forme narrative qui devrait les ordonner dans un récit unique ? Quoi de plus hétérogène que le vécu de l’individu contemporain, sans cesse sommé de s’adapter à de nouveaux rôles et de nouveaux projets ? Dans le cadre de cette communication, notre objectif sera d’évaluer la pertinence du concept d’identité narrative pour penser les modes de subjectivation individuelle, par le prisme de plusieurs romans contemporains (Farah, Delaume, Mérot, Minard, de Toledo, Vasset). Comment le récit de vie littéraire développe-t-il des formes qui puissent répondre aux expériences fragmentaires des sujets ? Ces formes renouvellent-elles l’usage de la narration et/ou de la fiction ? [less ▲]

Ion mobility spectrometry (IMS) is a gas phase separation technique which relies on differences in the collisional cross section (CCS) of ions. Ionic clouds of unresolved conformers overlapped if the CCS difference is below the instrumental resolution expressed as Ω/ΔΩ. The experimental arrival time distribution (ATD) peak is then a superimposition of the various contributions weighted by their relative intensities. We have developed a strategy for accurate drift time determination using traveling wave ion mobility spectrometry (TWIMS) of poorly and unresolved conformers. This method implements through a calibration procedure the link between the peak full width at half maximum (FWHM) and the drift time of model compounds for wide range of settings for wave heights and velocities. We modified a Gaussian equation which achieves the deconvolution of ATD peaks where the FWHM is fixed according to our calibration procedure. The new fitting Gaussian equation only depends on two parameters: The apex of the peak (A) and the mean drift time value (µ). The standard deviation parameter (correlated to FWHM) becomes a function of the drift time. This correlation function between µ and FWHM is obtained using the TWIMS calibration procedure which determines the maximum instrumental ion beam diffusion using ionic compounds which are detected as single conformers in the gas phase. This deconvolution process has been used to highlight the presence of poorly resolved conformers for couples of crown ethers and peptides leading to CCS determination in better agreement with quantum chemistry predictions.

Vertical matter transfer processes (bioturbation and <2μm translocation) in soils and their dynamics are up to now poorly constrained although they are responsible for the temporal evolution of the ecosystem services. In order to better constrain and quantify these processes, a kinetic quantification of the involved transfers based on vertical profiles of 210Pb (xs), 10Be and 137Cs has been developed for Luvisols in which soluble transfers could be neglected. The range of applicability of this type of approach was nevertheless not tested. In this work, we analyzed 210Pb (xs), 10Be and 137Cs in soils exhibiting gradients of organic matter, pH and < 2 μm fraction (Podzol, Andosol Ferralsol, Leptosol). Acidic soils and large organic matter contents were considered. The depth distribution of the studied isotopes was then interpreted as a function of the organic matter content, the soil pH and its < 2 μm fraction. This demonstrates that 10Be and 137Cs losses occur under soluble form in the Podzol, especially under forest, more acid, for the latter. Soluble 10Be transfers were also identified in the Andosol when they were considered as negligible in the Leptosol. For 210Pb (xs), soluble transfers are also probable for soils with pH less than 5.5 (Andosol and Ferralsol) and strong affinity for organic matter has been demonstrated. Thus, under acidic conditions and low < 2 μm fraction, soluble transfer cannot neglected anymore. [less ▲]
