Three culture Media: PBS; HAM F10 and B2 Menezo were used to compare and study the in vitro development of goats embryos. After 48h of culture in these media, the rate of Morulas developed was o%, 19% and 42% respectively, and that of blastocysts was 25%, 73% and 95%. The B2 Menezo medium would therefore appear well adapted to the culture of blastocysts. The morulas, however, irrespective of the medium used showed limited development. [less ▲]

In Belgium, several researchers have been highly active in developing pinhole tomoscintigraphy and have sometimes made a pioneer work. Their contributions concern as well the methodology of the technique as its applications to human and small animals. Reconstruction algorithms, of analytic and iterative type, have been developed and validated. They can reconstruct data obtained along circular, half-circular and non-circular acquisition orbits, the camera head being eventually tilted. A very performing method has been elaborated to determine the seven geometric parameters of the acquisition that are needed for an optimal reconstruction. The use of pinhole tomoscintigraphy for thyroid exploration seems to be born in Belgium and a few validation studies were conducted in the country. Potentials of pinhole tomography application to parathyroid or bone scintigraphy have also been considered. Finally, some research groups are using pinhole tomoscintigraphy for small animal studies.

This work is the continuation of a longstanding project which aims at developping a fixed-wing unmanned air vehicule. This UAV has a high-mounted wing, a pushing propeller and its designated payload is a stereoscopic camera fixed on the front of the fuselage, surrounded by a fixed plexiglas globe. Based on the four previous years of developpement, two colleagues and I have modified and developped the design further. This year, a real-scale wing was manufacturerd in order to conduct mechanical tests on it. Furthermore, a new, aerodynamic-efficient half-scale fuselage was developped to study the aerodynamics of the new design in the wind tunnel of the University of Liège. This report is articulated about four main chapters. The first develops the changes applied to the \textbf{modified fuselage}, the constraints we faced in conceiving it and experimental data gathered from the wind tunnel. Second, an \textbf{aerodynamic study} is conducted on the whole half-scale model, that is including a wing and an empennage. Alas, due to a technical problem with a 6-axes sensor of the wind tunnel, no equilibrium study has been conducted; only 3-axes mesures were available. Third, an in-depth study is conducted on the \textbf{propulsive system}. The motor was also tested in the wind tunnel in order to obtain the quadratic thrust curve, and hence the performances at take off and in flight. A design change to a twin-engine configuration is also introduced. Last, the \textbf{flight control surfaces} are sized following given flight constraints, and the servomotors acting on those surfaces are selected based on the couple computed at the hinge of the mobile surface. As such, this work tries to address some hurdles raised in the previous reports, particularly on the aerodynamic and performance side. [less ▲]

Contexte : La Faculté de Médecine de l’Université de Liège propose dès la 2ème année de son cursus un enseignement de type PBL. Nous avons étudié le développement des capacités de raisonnement en lien avec la base de connaissances et son utilisation. Méthodes : Le développement des capacités de raisonnement est étudié de façon transversale par l’utilisation d’un TCS ainsi que longitudinalement exploitant les résultats des évaluations certificatives de raisonnement. Les niveaux de certitude aux réponses correctes et incorrectes aux tests de connaissances sont utilisés pour calculer un indice d’auto-évaluation du champ des connaissances sous-jacentes au raisonnement. Par ailleurs, l’effet d’une consigne de validation du processus de raisonnement en cours de séance PBL a également été étudié. Résultats : La capacité de raisonnement est manifeste dès la 2ème année et augmente avec l’expérience. Elle est corrélée à la capacité d’auto-évaluation du champ des connaissances. De plus, la validation du processus de raisonnement peut être renforcée par une consigne explicite et favorise ainsi l’apprentissage du raisonnement. Conclusion : Ces résultats ont abouti à l’élaboration d’un modèle permettant de mettre en perspective les différents facteurs impliqués dans le processus d’apprentissage du raisonnement en lien avec la base de connaissances et son utilisation.

This project for the graduation of Mechanical Engineer has been realised in the Laboratory for Hydraulic Research of the Ministry of Equipment and Transport of Belgium. It consisted of the design and the realisation of a test bench for hydraulic control valves in preparation for qualified calibration (ISO 17025). Enventually measurement of actual flow characteristics will allow to optimise the use of valves in piping systems. The work has been done in several phases: design, study of metrology, study of standards, implementation and finally preliminary tests and results. The dimensioning of the test bench led to the drawings and draughts of all pipe sections and of the rejection canal (valves with diameter from 100 to 300 mm). The prssure drop has also been evaluated over the whole system. Concerning methodology, measuring techniques were identified, sensors and their signal handling units have been chosen and dimensioned: weirs, pressure sensor, torque meter and electromagnetic flow meter. With the aim to prepare the future qualification of the test bench, existing standards were identified and studied. Their recommendations have been applied where possible. Finally the test bench has been constructed, which has been a rich experience because of the many unexpected problems related to technique as well as to methodology. Preliminary test results for the calibration of a butterfly valve are promising. Nevertheless there is still some work to do before calibration can be qualified. Anyhow the data already collected and the many observations done during these tests were a good opportunity to analyse technological problems and standardisation. So this as a whole results in a data package which can be the base for future projects. [less ▲]
