La fréquence de fourbures rencontrées après une dystocie semble faible par rapport à la littérature. L’ajout d’héparines fractionnées aux traitements habituels de la métrite du post-partum (ocytocine, lavage utérins, antibiotiques et anti-inflammatoires) semble intéressant pour réduire le risque de fourbure.

Ekki, Lophira alata Banks ex C.F.Gaertn., is an African timber species occurring in tropical rainforests. Of important commercial value, this species is logged for its excellent timber properties and has been classified by the IUCN as «vulnerable" species. As for many other tropical tree species, the commercial exploitation of Ekki is confronted to an insufficient knowledge about the species’ ecological profile. With a distribution range limited to the Guinea-Congolian region, Ekki often displays insufficient natural regeneration, but the biotic and abiotic factors explaining this deficiency have been hardly characterized. This lack of knowledge makes it difficult to model the population dynamics on the long term. The reproductive biology of Ekki and the genetic variability of its population remains poorly studied too. To address this situation, a fundamental and applied research is being undertaken in the forest concessions managed by Wijma Cameroun SA., covering over 250,000 hectares of rainforest in Southern Cameroon. This study aims to answer four essential questions: (1) what is the phylogenetic relationship between L. alata and L. lanceolata, (2) how paleoclimate and human disturbances impact its distribution and abundance, (3) how to these populations respond to logging over several rotation periods, (4) does logging promote or inhibit the natural regeneration of the species. Several study devices have thus been installed to collect the data needed to improve the characterization of Ekki’s ecology and to conceive silvicultural strategies. [less ▲]

Les pratiques de catégorisation juridico-bureaucratique, mais aussi rhétorique occupent une place centrale au niveau des processus de constitution et de réinvention continuelle des Etats-nations comme les travaux de nombreux historiens l’ont montré. Aujourd’hui encore, la production et la circulation de catégories de l’altérité comme « immigré », « réfugié », « sans papier », « clandestin », « jeune des banlieues », etc. peuvent être pensées en rapport avec la constitution du « citoyen national » ainsi qu’avec valeurs et principes qui lui sont associés. Ces pratiques de catégorisation de la population participent de processus d’institution de relations de pouvoir. Ils touchent aux questions de construction sans cesse renouvelée de la légitimité des Etats, mais aussi au processus d’identification des groupes concernés. Cette problématique et cette dialectique « légitimation-identification » est particulièrement intéressante à étudier dans le cas des travailleurs d’origine rurale en République populaire de Chine. On s’intéressera à ces pratiques et luttes autour des catégories de discours car celles-ci participent, de configurations complexes d’institutions, de pratiques de contrôle social et de gouvernement. Ces catégorisations sont tour à tour le produit de ces configurations tout comme elles les constituent. Dans notre exposé, à travers une confrontation entre différents matériaux (presse, littérature migrante, chansons, entretiens, etc.), nous nous pencherons sur les relations de pouvoir et les luttes que recèle la catégorie de dagong (打工). Nous montrerons qu’elle cristallise tout un réseau de principes et de valeurs centraux dans la société chinoise post-maoïste et que la figure du « travailleur rural » (dagongzhe) concentre sur elle un champ normatif très dense. Nous nous poserons également la question de savoir quels outils conceptuels utiliser afin d’appréhender ces processus. [less ▲]

Motor prostheses aim to restore functions lost to neurological disease and injury by translating neural signals into control signals for prosthetic limbs. Despite compelling proof of concept systems, barriers to clinical translation—mainly strict power dissipation constraints—still remain. The proposed solution is to use the ultra-low-power neuromorphic approach to potentially meet these constraints. [less ▲]

We report the detection of CoRoT-23b, a hot Jupiter transiting in front of its host star with a period of 3.6314 \pm 0.0001 days. This planet was discovered thanks to photometric data secured with the CoRoT satellite, combined with spectroscopic radial velocity (RV) measurements. A photometric search for possible background eclipsing binaries conducted at CFHT and OGS concluded with a very low risk of false positives. The usual techniques of combining RV and transit data simultaneously were used to derive stellar and planetary parameters. The planet has a mass of Mp = 2.8 \pm 0.3 MJup, a radius of Rpl = 1.05 \pm 0.13 RJup, a density of \approx 3 g cm-3. RV data also clearly reveal a non zero eccentricity of e = 0.16 \pm 0.02. The planet orbits a mature G0 main sequence star of V =15.5 mag, with a mass M\star = 1.14 \pm 0.08 M\odot, a radius R\star = 1. 61 \pm 0.18 R\odot and quasi-solar abundances. The age of the system is evaluated to be 7 Gyr, not far from the transition to subgiant, in agreement with the rather large stellar radius. The two features of a significant eccentricity of the orbit and of a fairly high density are fairly uncommon for a hot Jupiter. The high density is, however, consistent with a model of contraction of a planet at this mass, given the age of the system. On the other hand, at such an age, circularization is expected to be completed. In fact, we show that for this planetary mass and orbital distance, any initial eccentricity should not totally vanish after 7 Gyr, as long as the tidal quality factor Qp is more than a few 105, a value that is the lower bound of the usually expected range. Even if Corot-23b features a density and an eccentricity that are atypical of a hot Jupiter, it is thus not an enigmatic object. [less ▲]
