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.

SWAP (Sun Watcher using Active Pixel System detector and Image Processing) is an instrument that has been selected to fly on the PROBA-II technology demonstration platform, a program of the European Space Agency (ESA) to be launched in 2006. This paper presents the instrument concept and its scientific goals. SWAP uses an off-axis Ritchey Chretien telescope that will image the EUV solar corona at 19.5 nm on a specifically fabricated extreme ultraviolet (EUV) sensitivity enhanced CMOS APS detector. This type of detector has advantages that promise to be very profitable for solar EUV imaging. The SWAP design is built on a similar concept as the MAGRITTE instrument suite for the NASA Solar Dynamics Observatory (SDO) mission to be launched in 2007. The optics have been adapted to the detector size. The SWAP PROBA-2 program will be an opportunity to demonstrate and validate the optical concept of MAGRITTE, while it will also validate space remote sensing with APS detectors. On the science outcomes, SWAP will provide solar corona images in the Fe XII line on a baselined 1-min cadence. Observations with this specific wavelength allow detecting phenomena, such as solar flares or 'EIT-waves", associated with the early phase of coronal mass ejections. Image recognition software will be developed that automatically detects these phenomena and sends out space weather warnings. Different modules of this software will run both on the ground system as well as on the onboard computer of PROBA II. The SWAP data will complement the observations provided by SOHO-EIT, and STEREO-SECCHI. [less ▲]

High Speed Steel (HSS) cast rolls are used in front finishing stands of hot strip mills. Good wear resistance and hardness at high temperatures, are defining features of HSS. Many types of carbides are present in these alloys, each having different effect upon their final properties. As a result, nature, morphology and amount of these carbides are factors of important concern. Identification and characterisation of carbides were realised. MC, M2C, M7C3 carbides were found. Some relationships with mechanical properties were obtained especially in the field of the solidification sequence that affects grain size and carbides dispersion. [less ▲]

Allogeneic hematopoietic stem cell transplantation (HSCT) is used for the treatment of selected hematological malignancies. Its curative potential is based on two very different mechanisms, involving the conditioning regimen and the graft-versus-host reactions, respectively. The high-dose chemo-radiotherapy conditioning regimen is aimed at destroying tumor cells, ablating the host immune system (to prevent rejection) and eliminating the host bone marrow (to "make space" for donor stem cells). However, the definitive eradication of tumor cells is also largely mediated by an immune-mediated destruction of malignant cells by donor lymphocytes termed graft-versus-leukemia (GVL) or graft-versus-tumor (GVT) effect. However, because of its toxicity, conventional allogeneic HSCT is restricted to younger (< 55 years) and fitter patients. These observations led several groups to set up new (less toxic) transplant protocols based on a two step approach: first the use of immunosuppressive (but nonmyeloablative) conditioning regimens providing sufficient immunosuppression to achieve engraftment of allogeneic hematopoietic stem cells and, in a second step, destruction of malignant cells by the GVL effect. These transplants are called nonmyeloablative HSCT or reduced-conditioning HSCT or minitransplants. Preliminary results show that minitransplants are feasible with a relatively low transplant-related mortality (TRM) even in patients up to 70 years. In addition, strong anti-tumor responses are observed in several hematological malignancies as well as in some patients with renal cell carcinoma. As the benefits of minitransplants over alternative forms of treatment remain to be demonstrated, this strategy should be restricted to patients included in clinical trials. [less ▲]

This study examines the prognostic significance of pathologic factors in patients with primary locally advanced rectal cancer treated prospectively with preoperative radiotherapy. From 1992 to 1998, 104 patients with rectal cancer of grades T3 or T4 and any N underwent preoperative radiotherapy followed by surgical resection. Survival curves were estimated according to the Kaplan-Meier method. Correlation of outcome with clinicopathologic variables (pathologic tumor and lymph node staging, histology, radial resection margin [RRM], clearance, vessel involvement, and tumor regression grade [TRG], quantitated in 5 grades) was evaluated using the Cox proportional hazards model. None of the patients achieved a histologically confirmed complete pathologic response, but 79% of the patients showed partial tumor regression (TRG2–4) and 21% did not show any tumor regression (TRG5). Among the tumors, 22% were of a mucinous type. The RRM was free of tumor in 76% of the surgical specimens. The median clearance was 2 mm. Vascular invasion was present in 37 cases (36%). In the univariate analysis, lymph node metastases, absence of tumor regression, positive RRM, and vascular invasion were correlated with adverse overall survival and diseasefree survival; absence of tumor regression, positive RRM, and clearance <2 mm were correlated with local recurrences; and advanced pT stage was correlated only with disease-free survival. However, in the multivariate analysis, only lymph node metastases and RRM were independent prognostic factors for overall survival and disease-free survival, and clearance <2 mm was an independent prognostic factor for local control. Pathologic parameters remain strong determinants of local recurrence and survival in locally advanced rectal cancer, treated preoperatively with hyperfractionated and accelerated radiotherapy. We show that patients with advanced pT, positive lymph nodes, vascular invasion, positive RRM, clearance <2 mm, or absence of tumor regression are known to have poor clinical outcome.
