De nombreux travaux montrent que les évolutions urbaines contemporaines s’inscrivent dans un processus de recomposition des villes induit par la mobilité facilitée et par la banalisation de la conduite automobile. Dans le cadre de cet article, nous traitons cette thématique en étudiant, pour le contexte belge, comment le relâchement des freins à la mobilité interfère avec les logiques résidentielles des familles en formation. Un bilan sur la situation contemporaine est d’abord dressé. Nous y présentons les principaux liens entre choix résidentiels, classes d’âges et parcours de vie. Nous y analysons aussi les relations entre, d’une part, le constat de l’étalement périurbain et, d’autre part, la pression foncière à laquelle les ménages en formation ont à faire face. En seconde partie, la situation contemporaine est confrontée aux évolutions des cinq dernières décennies. Ces analyses réalisées pour la région urbaine de Liège permettent de combiner les trois grilles explicatives du moment du cycle de vie, de l’effet du renouvellement des générations et de l’impact du contexte socio-économique. De ce travail, nous relevons que la mobilité facilitée conduit à dilater les inscriptions démographiques. Comme les groupes sociaux, les groupes démographiques sont, en effet, de plus en plus spatialement ségrégés dans une région urbaine très largement recomposée par la mobilité automobile. [less ▲]

Le livre reprend 10 contributions issues d'un colloque organisé en 2004 à Bruxelles. Il aborde les relations entre mobilité et temporalité qui conjuguent deux préoccupations contemporaines s'alimentant l'une l'autre. D'une part la question des mobilités et d'autre part la question du temps (du discours sur son accéleration à celui de son individualisation). [less ▲]

This study performed in the Patapedia River (Quebec, Gaspesie) was designed to examine the space utilization and mobility patterns of individual Atlantic salmon parr over short time scales with frequent detections of position. In August 2004, n = 7 radio-tagged Atlantic salmon parr were located every 20 min during 10 tracking periods chosen to take into account the dawn, day, dusk and night periods. Parr showed important inter individual variability in space utilization and mobility patterns, occupying large home ranges (123 to 5602 m(2)) and sometimes migrating 2 km upstream in the river. No differences were observed in the mean distance travelled among the four daily periods by individual fish, but the estimated home ranges utilized during the four daily periods overlapped only partially, demonstrating that parr partly occupy different areas of the river during different parts of the daily cycle. The results suggest that an intense survey on a small number of fish may contribute to a complementary comprehension of space utilization and mobility patterns of Atlantic salmon parr when viewed in association with results from studies surveying larger number of fish at lower frequency.

Adult roach Rutilus rutilus (L.) (N = 24; 19.9-36.1 cm FL) from three highly fragmented Belgian rivers were tagged with surgically implanted radio transmitters. Their seasonal movements were observed from March to August 2004 (circum reproduction period) in river stretches delimited by two physical barriers. In the three rivers, roach displayed similar patterns of movements which were mainly influenced by the date of observation (movements increased in late April-May) and water temperature (travel distances were more important when water temperature ranged between 10 degrees C and 14 degrees C). Roach sometimes cleared physical obstacles. The mean distances travelled in each river were relatively short (max. 2.5 km) and mainly influenced by the length of the study reach, which was delimited by physical barriers. [less ▲]

Several mechanisms increase the QoS level of mobile networks thanks to an underlying mobility prediction method (i.e. a means to predict a mobile's next access router). This paper aims at studying how the accuracy of the prediction method can influence the network QoS in the particular context of call admission control. It shows that (a) the mobiles behaviour must be adapted according to the prediction scheme accuracy in order to achieve good performance and (b) the admission algorithm can be modified to increase its fairness and to give mobiles an incentive to do such an adaptation.

AquaTerra is one of the first environmental projects within the 6th Framework program by the European Commission. It began in June 2004 with a multidisciplinary team of 45 partner organizations from 13 EU countries, Switzerland, Serbia, Romania and Montenegro. Results from sampling and modeling in 4 large river basins (Ebro, Danube, Elbe and Meuse) and one catchment of the Brévilles Spring in France led to new evaluations of diffuse and hotspot input of persistent organic and metal pollutants including dynamics of pesticides and polycyclic aromatic hydrocarbons, as well as metal turnover and accumulation. While degradation of selected organic compounds could be demonstrated under controlled conditions in the laboratory, turnover of most persistent pollutants in the field seems to range from decades to centuries. First investigations of long-term cumulative and degradation effects, particularly in the context of climate change, have shown that it is also necessary to consider the predictions of more than one climate model when trying to assess future impacts. This is largely controlled by uncertainties in climate model responses. It is becoming evident, however, that changes to the climate will have important impacts on the diffusion and degradation of pollutants in space and time that are just at the start of their exploration.

Northern elephant seals (Mirounga angustirostris) are characterized by extended fasting during which they rely entirely on their own body reserves. During fasts, lipids are mobilized from blubber to match the energy requirements of the animal. This transfer frees toxic fat-soluble pollutants into the blood circulation, which may exert adverse health effects, especially in young and developing animals. We investigated the dynamics of mobilization of polychlorinated biphenyls (PCBs) from the blubber of northern elephant seal pups during the post-weaning fast. Longitudinal samples of blubber and serum were collected from free-ranging animals throughout the fast at Ano Nuevo, California. Blubber biopsies were separated into inner and outer layers. The PCB profiles of blubber and serum consisted mainly of penta- (PCB-101, -110, -118), hexa- (PCB-138, -153) and hepta- (PCB-180, -183, -187) chlorobiphenyls, which accounted for almost 90% of the total PCB burden. Total PCB concentrations in inner blubber increased significantly between early and late fasting (563.6 +/- 162.0 mu g/kg lipids at early versus 911.6 +/- 513.1 mu g/kg lipids at late fasting) whereas they remained fairly constant in outer blubber (572.6 +/- 134.8 mu g/kg lipids at early versus 659.2 +/- 158.8 mu g/kg lipids at late fasting). A corresponding rise of PCB concentrations was observed in serum during the second half of the fast (3.8 +/- 1.1 mu g/l serum at early versus 7.2 +/- 0.9 mu g/l at late fasting). The longitudinal changes in circulating total PCBs could not be explained by the changes in serum lipid fractions (cholesterol, phospholipids, triacyl glycerols and free fatty acids). The increases in total PCB concentrations in inner blubber and serum were more pronounced in leaner animals, which suggests that they might be more at risk to potential toxic effects.
