Fractionated whole body X-irradiation (4 X 1.75 Gy at weekly intervals) induces a high percentage of thymic lymphomas in C57BL/Ka mice. These tumors develop after a long latency period during which the thymic lymphopoiesis is deeply altered. In the present work, we test wether those modifications are due to lack of prothymocyte homing to preleukemic thymuses. Our results show that the preleukemic state of the thymus don't prevent the homing of normal marrow precursors grafted immediately after an irradiation of 4 Gy. Thus the alterations of thymic lymphopoiesis observed after a leukemogenic irradiation are not due to a modification in the thymus receptivity to thymocyte precursors. [less ▲]

L’objectif de cette recherche consiste à étudier les processus économiques, politiques et sociaux ayant favorisé la diffusion de pratiques criminelles et mafieuses chez certains migrants d’origine italienne en Belgique. Nous émettons l’hypothèse que l’apparition de pratiques mafieuses ne se fait pas via l’exportation des activités criminelles sur une « base ethnique » d’un lieu à un autre, mais que ces pratiques se développent à la suite d'une adaptation aux contextes d’immigration où se vérifient toutes les conditions de transformation du parcours d’intégration de certains migrants en un parcours criminel ou mafieux. C’est pour cela que nous proposons un nouveau cadre théorique qui dépasse les interprétations habituelles sur les phénomènes mafieux dans les parcours d’immigration et qui se propose d’étudier le vaste et complexe système de relations dans lequel les forces criminelles s’enracinent. Pour ce faire, nous proposons de nous concentrer sur l’étude du secteur agroalimentaire et de la restauration dans lesquels la criminalité d’origine italienne a beaucoup investi durant les dernières décennies. Par ailleurs, nous proposons une analyse comparée à la société d’origine des migrants, le Sud de l’Italie, afin de comprendre les continuités et les ruptures dans les pratiques mafieuses entre les contextes d’origine des migrants et ceux présents dans les espaces d'immigration. Pour tester les hypothèses, cette recherche se base sur l’étude de la littérature scientifique, les données statistiques de la criminalité, les sources médiatiques, sur quelques dossiers figurant dans les archives judiciaires des tribunaux belges. Mais, la recherche est surtout basée sur une approche ethnographique qui repose sur des recueils biographiques, de récits familiaux et de l'observation participant en travaillant comme agent pour une entreprise d'import/export de produits italiens.

Previous publications on the migration and movements of kingfisher s have been limitid to a few countries; there has not been any previous synthesis of the data from the whole of Europe. The present study,based on the Euring database, related to the movements of 5991 ringed and recaptured birds. The data were classified according to the status of each individual (pulli, juvenile or adult) as noted at ringing, the time of year (autumn and winter; spring; breeding period), and general geographical area. In the first autumn and winter, half of the pulli remained in the nesting area. Those that did move (between 25 and 250 km) dispersed approximately equally in all directions. The tendency to migrate was most marked among birds born in Sweden. The tendency decreases progressively in the sequence North Europe/Central Europe/ North Western Europe, where only 5 % of birds migrate, moving in a southwesterly direction. Juvenile birds are less mobile (approximately 80 %) than the pulli. Those which do move have the same pattern of dispersion as the pulli. The tendency to migrate is especially marked in North Europe, and is almost non existent in Gread Britain and in the Mediterrannean peninsulas. In springtime, most birds are already nesting, but some migrate towards the N or NE, and some are delayed in their overwintering location. During the nesting period, the ex pulli rarely take over the burrow where they were born, while the majority of juveniles tend to remain in the area where they were first captured. Some adults do change area ot the time, this tendeny being more accentuated among females, while male birds appear to be more attached to their home territory. In subsequent autumns the patterns of dispersion, of distance and of direction of ex juveniles and ex pulli are indistinguishable from those of the first automn. In Sweden the adults migrate, whereas elswhere adults have similar behaviour as juvenile birds; but adults are even more sedentary. [less ▲]

This paper presents the results of a detailed field investigation that was performed for studying groundwater recharge processes and solute downward migration mechanisms prevailing in the unsaturated zone overlying a chalk aquifer in Belgium. Various laboratory measurements were performed on core samples collected during the drilling of boreholes in the experimental site. In the field, experiments consisted of well logging, infiltration tests in the unsaturated zone, pumping tests in the saturated zone and tracer tests in both the saturated and unsaturated zones. Results show that gravitational flows govern groundwater recharge and solute migration mechanisms in the unsaturated zone. In the variably saturated chalk, the migration and retardation of solutes is strongly influenced by recharge conditions. Under intense injection conditions, solutes migrate at high speed along the partially saturated fissures, downward to the saturated zone. At the same time, they are temporarily retarded in the almost immobile water located in the chalk matrix. Under normal recharge conditions, fissures are inactive and solutes migrate slowly through the chalk matrix. Results also show that concentration dynamics in the saturated zone are related to fluctuations of groundwater levels in the aquifer. A conceptual model is proposed to explain the hydrodispersive behaviour of the variably saturated chalk. Finally, the vulnerability of the chalk to contamination issues occurring at the land surface is discussed. (C) 2003 Elsevier B.V. All rights reserved. [less ▲]
