Attempts were made to establish models to study interactions between marrow stromal cells and hematopoietic cells in vivo. The approach was to create a NOD-SCID-hu murine model of long-term human hematopoiesis by implantation of a human adult bone fragment. Nine to 12 weeks posuransplantation, human CD45(+) cells were detected in the blood and the spleen of some mice. The histology of the human transplant showed that human bone fragment was viable at 9 weeks. Moreover, vessels of human origin, as assessed by immunohistochemical detection of human beta(2)-microglobulin, were observed in the mouse tissue surrounding the transplanted human fragment.

We present the discovery context of Neolithic ceramic sherds from stratum 4 (attributed to the Late Mesolithic) at Trou Al'Wesse. The spatial distribution of the archaeological materials, as well as stratigraphic data, demonstrate that these sherds are not associated with the Mesolithic assemblage. Thestratigraphy also shows that, near the cliff face, there is no mixing between the two occupations. [less ▲]

This paper presents the numerical studies lead by the Laboratory of Applied Hydrodynamics and Hydraulic Constructions of the University of Liège (HACH) for the rehabilitation of the 21-meter high Nisramont dam in Belgium. After determination of the up-to-date 1000-year return flood using the hydrological runoff model WOLFHYDRO on the global 74,000 ha watershed real topography coupled with statistical analyzes, and after validation on the existing situation and for extreme observed events, the 2D finite volume multiblock flow solver WOLF2D has been applied to the design of the new stilling basin and to the bottom outlet rehabilitation impact study. The multiblock solver possibilities allow mesh refinement close to interesting areas, such as dam spillway and stilling pool, without leading to prohibitive CPU times, while suitable shallow water equations formulation allows the computation of the flows on the strongly vertically curved bottom of the spillway. In the described simulation, 270,000 structured finite volumes, from .25 to 1 meters long, are used to simulate as a whole the flows in the upstream reservoir, dam, spillway, stilling basin and downstream river, this on a real topography.

In the last years, Europe was subject to catastrophic inundations. At the same time, computer's capacity are increasing such as bidimensional simulations can be applied to real cases. Two compementary theoretical and numerical models are presented and discussed in the present paper: the diffusive approximation and the complete shallow-water approach. An original refinement of meshes is also presented to increase the convergence speed to a steady solution. Numerous comparisons between models and methods of resolution are described. Finally, an example of determination of the flood extension on a natural river is illustrated. [less ▲]

The quasi-3D flow solver WOLF has been developed at the University of Liege for almost a decade. It has been used to carry out the simulation of silting processes in large reservoirs and to predict the efficiency of flushing operations. Besides briefly depicting the mathematical and numerical model, the present paper demonstrates its applicability on the case of a large hydropower project in India. The silting process of the reservoir has been simulated by means of the quasi-3D flow model with a quasi-steady approach. For simulating flushing events, both the topography changes and their interactions with the flow have been carefully handled in a strongly coupled approach. This narrow coupling has required the development of a suitable upwind numerical scheme. Results are presented with 2D- and 3D-views, completed by cross-sections and curves of the variation of key variables. The numerous observations based on those results lead to a global assessment of the silting mechanism and of the flushing efficiency. [less ▲]

This paper presents the scale model studies of a complex under pressure settling structure, carried out at the Laboratory of Hydraulic Constructions of the University of Liège. Made up of fourteen identical settling chambers placed side by side and the bottom of which is divided into pyramidal hoppers, the structure, totally under pressure, is fed by a vertical shaft. Downstream, the settling chambers discharge into a collector, which ensures the clean water feeding of four penstocks through a free surface basin. Finally, a pipes network, under the chambers, ensures the downstream evacuation of the sand trapped in the hoppers. Using adapted and theoretically justified similarity laws coupled with realistic scales for the models, the hydrodynamic behavior and solid transport phenomena in this complex system have been studied. Special care has been taken to evaluate the trap efficiency, the evacuation system working and the global discharge repartition between the fourteen chambers. Sawdust, plastic balls or very small sand particles have been used to model real sediments. A total of three models, from only one hopper to the full settling structure, have been built, with scales from 1/18.5 to 1/100. According to the results of the studies, the length of the settling chambers has been shortened of up to 38 meters, i.e. 2 hoppers, and best use instructions have been suggested for the sediment evacuation system.

The paper covers a brief description and a comprehensive comparative analysis of several state-of-the-art dam breaching models. The study is specifically focused on the applicability and on the predictive capacity of the models for the gradual breaching of an overtopped rockfill dam. A wide range of modelling techniques is reviewed, from process-oriented numerical simulations to empirical models. Comparisons are performed regarding various aspects, such as the applicability of the model without prior calibration or the possibility of coupling the breaching model with a quasi-3D flow solver such as WOLF. Finally, a sensitivity analysis of the downstream hydrograph to various parameters is conducted and the conclusions drawn are illustrated in the case of a large-scale real application in Belgium.

L'industrie belge a-t-elle fait, dans la première moitié du XXème siècle, l'expérience de ce qui, dans des pays voisins, a été étudié sous le nom de rationalisation, ou en a-t-elle été empêchée par la prépondérance en son sein d'activités anciennes, nées de la Révolution industrielle? Pour répondre à cette question, ce livre fait le choix de donner un très large aperçu de mesures d'organisation, saisies autant que possible à l'échelle de l'atelier; il prend appui sur le dépouillement de nombreux fonds d'archives d'entreprises et d'une abondante littérature technique, patronale et syndicale. Il s'attache d'abord aux pratiques d'organisation présentées en référence non exclusive à la taylorisation, à la recherche de la fluidité du processus de production et aux techniques de contrôle centralisé des exploitations; il réserve ensuite une large attention à la gestion du facteur humain, depuis la formation et la sélection professionnelles jusqu'à la politique sociale patronale, en passant par la question du commandement. Enfin, il tente de mesurer l'impact du changement organisationnel sur les conditions d'activité des travailleurs, de saisir leurs réactions et celles du mouvement ouvrier organisé. S'en dégage un bilan nuancé de la rationalisation dans l'industrie belge à la veille de la Seconde Guerre mondiale, prenant en compte le poids de la conjoncture, les contraintes structurelles, internes et externes aux entreprises, et le jeu — conflictuel ou coopératif — des acteurs.

The inhalation route is widely studied for many drug applications focusing on either local or systemic distributions. One matter of concern is the solubilization of hydrophobic drugs. We have studied the feasibility of using different cyclodextrins (CDs) to elaborate pharmaceutical formulations for the inhalation route and tested the short-term toxicity of such formulations administered by inhalation to C57BL/6 mice. We have shown that HP-beta-CD, gamma-CD, as well as RAMEB aqueous solutions can undergo aerosolization and that the resulting droplet-size ranges are compatible with pulmonary deposition. In vivo, we have demonstrated that short-term exposure to inhaled HP-beta-CD, gamma-CD and RAMEB solutions are non-toxic after assessing bronchoalveolar lavage (BAL), lung and kidney histology, bronchial responsiveness to methacholine and blood urea. The only change noted is a slight increase in lymphocyte count in the BAL after HP-beta-CD and gamma-CD inhalation. We conclude that CDs are useful in significantly enhancing the solubility of apolar drugs with a view to inhalation therapy although an increase in lymphocyte counts in the BAL after CDs inhalations needs further investigations.
