Cet article analyse les conflits qui, en France, sont liés à l'usage du poison pour lutter contre la prolifériation du campagnol terrestre, du ragondin et du rat musqué. Avec le concept d'agencement s; emprunté au philosophe Gilles Deleuze, nous décrivons ces situations comme des façons mouvantes et interactives par lesquelles des forces diverses définissent les problèmes et redistribuent les places de chacun, humains et animaux, dans des paysages et au moyen de techniques qui suscitent des polémiques. Ces agencements sont des moments au croisement de plusieurs histoires entremêlées, moments tantôt conflictuels, tantôt porteurs de coexistence. Des états de paix sont négociés, mais ils restent fragiles et ils sont susceptibles d'autres résistances ou défaillances. [less ▲]

The two types of endometrial carcinomas are preceded by precancerous lesions. Type I endometrial carcinomas are most commonly encountered in perimenopausal women with the classical risk factors associated with estrogen exposure: obesity, multiparity, diabetes, estrogen treatment, ... Hyperplasia (simple, followed by complex forms without cellular atypias and subsequently by complex hyperplasias with cellular transformation) precede such cancers. Estrogens exert a promoting effect on these lesions but do not initiate them. Progesterone and progestins exert a preventive and protective effect. However, the progressive loss of steroidal receptors is correlated to the progression of tissular anomalies and to the onset of cytogenetic anomalies and to mutations of p53 anti-oncogene. The preventive role of progestin is well established, but their curative beneficial effect on atypical precursors forms of endometrial cancers and on endometrial carcinomas remains controversial. The second type of endometrial cancer appears during the postmenopause and is characterized by an increased invasiveness and a poor prognosis, devoid of identifiable risks factors, these aggressive cancers are not preceded by hormone-sensitive precancerous lesions, but by an intra-epithelial endometrial carcinoma. This lesion appears most often in an atrophic endometrium. Finally, the two types of precancerous states are characterized by distinct gene anomalies suggesting two different pathogenic mechanisms of cancerisation. [less ▲]

Using a model of experimental leukemia in mice, we have demonstrated that tumor development depends upon interactions between preleukemic cells and their microenvironment whose functions are altered. Cytokine injections inhibit tumor development by inducing a functional restoration of this environment. Human myelodysplastic syndromes (MDS) are marrow pathologies considered as preleukemic stages. As in murine leukemias, it is possible that marrow environment could play a key role in their evolution. We currently establish a model of human hematopoiesis in NOD/SCID mice grafted with human bone fragments. We hope that this model would allow to analyse the role of the marrow stromal cells in MDS and to establish treatments restoring their functions. [less ▲]

This paper addresses a new approach to formalize the spatiotemporal relationships between geographical objects that do not exist or that are not present at the time of the analysis. We propose first an analysis of the spatiotemporal states of existence and presence for a geographical object. Then, we combine the spatiotemporal states to define a comprehensive set of life and motion configuration. The proposed model serves as formal basis to perform spatiotemporal queries by retrieving selected patterns in the life and motion configurations. The research is applied to the organization of a scientific conference, in doing so we are able to define the relationships that exist between an event located in space and time and mobiles objects evolving within the space, i.e. the conference participants.

Résumé : En parcourant les nombreuses études qui décrivent et analysent, depuis plus de vingt ans, le fonctionnement des organisations et des politiques pénitentiaires, trois questions semblent avoir jusqu’ici suscité un moindre intérêt scientifique : qui dirige ces organisations ? En quoi consiste le travail des équipes de direction ? Quelle position les membres de ces équipes occupent-ils dans le système organisationnel et politique pénitentiaire belge ? Cet article apporte quelques éléments de réponse à ces questions tout en éclairant les recompositions des contextes de travail des équipes de direction pénitentiaire. Cet éclairage souligne la nécessité de définir politiquement et avec les principaux intéressés un processus de professionnalisation de la fonction qu’ils exercent. [less ▲]

We have fabricated curved optical micromirrors on silicon. We expect to be able to form open optical cavities between these mirrors and plane mirrors coated on the ends of optical fibres. The curved mirror templates have been prepared with less than 10 nm surface roughness by means of isotropic chemical etching. Two different methods are used for the fabrication of the mirrors: the first method uses a silicon oxide mask, while the second uses dry etching to form an indentation in the silicon surface that is opened out by wet isotropic etching. After coating the silicon substrate with gold, good quality mirrors are obtained with R ∼ 98% in the near infra-red. We find that a reflectivity of approximately 98% can be achieved by this method. Cavities formed from these mirrors will be useful for manipulating single atoms. [less ▲]
