L’approche proposée par le projet existe dans la combinaison des besoins en formation des ingénieurs de haut niveau de l’EIER d’une part avec les besoins de la DRH-HB d’autre part. En utilisant le système d’information géographique de la DRH-HB le projet a comme objectif de développer des outils informatiques qui peuvent aider à gérer mieux l’eau et qui ont la capacité de formuler une estimation précise du rendement des cultures pluviales dans la région pendant la saison. Afin de garantir des effets multiplicateurs et spin-off, et de disposer d’un nombre suffisant de chercheurs qui travailleront dans le cadre du projet sans exagérer les coûts, les outils seront développés dans le cadre des mémoires de fin d’études des meilleurs étudiants africains des quatorze états subsahariens de l’EIER et des étudiants des Universités flamandes.

Existing concrete surfaces need to be roughened to a profile necessary to achieve mechanical interlock with repair material. Surface mechanical morphometry is based on the measurement of surface profile - profilometry - which can be extended to 3D representation with surfometry by means of a stylus registering the profile. Profilometry and surfometry analysis were realized on concrete after different surface treatments (grinding, sandblasting, shotblasting, hand- and mechanical milling). The profile has been quantified by means of statistical and amplitude parameters calculated from the waviness (lower frequencies) and the roughness (higher frequencies) profiles of the surface. Bearing ratio and Abbott's curve observations are also very useful to characterise surface profiles. [less ▲]

Few studies have been performed to assess the risk of skin damage by cyclodextrins (CD) and they have yielded contradictory results. The present study was conducted using the corneoxenometry bioassay on human stratum corneum to compare the skin compatibility of CD currently used in pharmaceutical preparations (betaCD, gammaCD, Rameb, Dimeb, Trimeb, HP-betaCD and HP-gammaCD) and that of new amphiphilic CD derivatives, namely, the phospholipidyl-CD (DMPE-Dimeb and DMPE-Trimeb). All the tested CD were well tolerated by the stratum corneum at a concentration of 5%. However, inter-individual reactivity was larger for DMPE-Dimeb, suggesting a more aggressive trend for this compound. Cutaneous Index of Mildness values obtained confirm that Dimeb is able to extract some skin components and shows that DMPE-Dimeb performs similarly. [less ▲]

(E)-20-Deoxy-20-(fluoromethylene) cytidine (FMdC), an inhibitor of ribonucleotide diphosphate reductase (RR), is a potent radiation-sensitiser acting through alterations in the deoxyribonucleoside triphosphate (dNTP) pool in the de novo pathway to DNA synthesis. The activity of thymidine kinase (TK), a key enzyme in the ‘salvage pathway’, is known to increase in response to a lowering of dATP induced by FMdC. Nucleoside analogues such as iododeoxyuridine (IdUrd) are incorporated into DNA after phosphorylation by TK. Radiation sensitisation by IdUrd depends on IdUrd incorporation. Therefore, we have investigated the radiosensitising effect of the combination of FMdC and IdUrd on WiDr (a human colon cancer cell-line) and compared it to the effect of either drug alone. We analysed the effects of FMdC and IdUrd on the dNTP pools by high-performance liquid chromatography, and measured whether the incorporation of IdUrd was increased by FMdC using a [125I]-IdUrd incorporation assay. The combination in vitro yielded radiation-sensitiser enhancement ratios of >2, significantly higher than those observed with FMdC or IdUrd alone. Isobologram analysis of the combination indicated a supra-additive effect. This significant increase in radiation sensitivity with the combination of FMdC and IdUrd could not be explained by changes in the dNTP pattern since the addition of IdUrd to FMdC did not further reduce the dATP. However, the increase in the radiation sensitivity of WiDr cells might be due to increased incorporation of IdUrd after FMdC treatment. Indeed, a specific and significant incorporation of IdUrd into DNA could be observed with the [125I]-IdUrd incorporation assay in the presence of 1 lM unlabelled IdUrd when combined with FMdC treatment. 2004 Elsevier Ltd.

Purpose: To assess the patterns of failure in the treatment of early-stage squamous cell carcinoma of the glottic larynx. Patients and Methods: Between 1983–2000, 122 consecutive patients treated for early laryngeal cancer (UICC T1N0 and T2N0) by radical radiation therapy (RT) were retrospectively studied. Male-to-female ratio was 106 : 16, and median age 62 years (35–92 years). There were 68 patients with T1a, 18 with T1b, and 36 with T2 tumors. Diagnosis was made by biopsy in 104 patients, and by laser vaporization or stripping in 18. Treatment planning consisted of three-dimensional (3-D) conformal RT in 49 (40%) patients including nine patients irradiated using arytenoid protection. A median dose of 70 Gy (60–74 Gy) was given (2 Gy/fraction) over a median period of 46 days (21–79 days). Median follow-up period was 85 months. Results: The 5-year overall, cancer-specific, and disease-free survival amounted to 80%, 94%, and 70%, respectively. 5-year local control was 83%. Median time to local recurrence in 19 patients was 13 months (5–58 months). Salvage treatment consisted of surgery in 17 patients (one patient refused salvage and one was inoperable; total laryngectomy in eleven, and partial laryngectomy or cordectomy in six patients). Six patients died because of laryngeal cancer. Univariate analyses revealed that prognostic factors negatively influencing local control were anterior commissure extension, arytenoid protection, and total RT dose < 66 Gy. Among the factors analyzed, multivariate analysis (Cox model) demonstrated that anterior commissure extension, arytenoid protection, and male gender were the worst independent prognostic factors in terms of local control. Conclusion: For early-stage laryngeal cancer, outcome after RT is excellent. In case of anterior commissure extension, surgery or higher RT doses are warranted. Because of a high relapse risk, arytenoid protection should not be attempted. [less ▲]

The influence of a periodic landscape of pinning sites on the vortex dynamics in Pb thin films is explored by ac susceptibility measurements. For different amplitudes h of the ac drive, the ac susceptibility chi=chi'+ichi" exhibits a complex field dependence associated with different dynamic regimes. At very low ac drives where both multiquanta vortices trapped by the antidots and interstitial vortices oscillate inside the pinning potential (intravalley motion), a small kink in chi'(H) together with a very low dissipation is observed. At intermediate ac excitations such that vortices in the antidots remain pinned, whereas interstices are driven out of the pinning well, a more pronounced kink in the screening coinciding with the onset of dissipation [chi"(H)not equal0] indicates the entrance of interstitial vortices. Eventually, at high enough amplitudes all vortices are set in motion and the penetration of interstitial vortices appears as a sudden reduction of the shielding power. We show that these distinctive features allow us to identify clearly the maximum number of flux quanta per hole, regardless of the vortex dynamic regime. [less ▲]

For five years, a postgraduate program in Educational and Training Technology has been developed by both Universities of Liège and Namur (Belgium). This program addresses already graduated adults having a training background. Depending on his/her training experience and a personnal project, the participant has the opportunity of developing different competencies profiles like: educational designer, designer and manager of training systems integrating ICT, e-tutor or trainer in e-learning environments, designer and producer of information or learning multimedia products. The plan of action articulates face-to-face and distance activities. It is based on several principles like definition and follow-up of a personal learning project, clarification of the actors’ roles, systematical use of technologies, active pedagogical methods and quality process. The authors present a series of scenarios including several types of distance activities. On the one hand, they illustrate these activities, insisting on their target goals, their meaning and usefulness, their development and their evaluation criteria. On the other hand, they discuss the organization of face-toface, blended or distance activities taking into account different sides of a learning system in order to stimulate the thought of designers and animators of such learning environments.

Erysipelas is a serious infection of the skin. In case of delay in initiating adequate antibiotic treatment, complications, sometimes dismal, can supervene. In addition, erysipelas shows a tendancy to recurrences. The prevention of an episode of erysipelas calls for correct personal hygiene and adequate use of topical antiseptics in case of skin effraction, even when minimal. When erysipelas is established, a rapidly initiated antibiotic treatment for a prolonged period prevents streptococcal gangrene complications. Elastic contention of any leg edema from venous or lymphatic origin and prophylactic antisepsis of discrete wounds help in preventing erysipelas recurrences. [less ▲]
