We are facing a real technical revolution in radiation oncology. The radiation oncologist is pushed by the industry to implement rapidly new and "high-tech" therapeutic modalities. All of the technical improvements are obviously aiming at an increase in the therapeutic index. However, one should be cautious before implementing on a large scale those technical innovations as no one really knows neither what the possible impact is on medical outcome (efficacy, toxicity and risk), nor what the economical consequences will be. It is our duty as radiation oncologists to make a comprehensive estimation of the impacts in order to be able to set up guidelines for use that are both ethical and in respectful of human dignity.

Activeandpassivemeasurementsfortopologydiscoveryhave known an impressive growth during the last decade. If a lot of work has been done regarding inter-domain topology discovery and modeling, only a few papers raise the question of how to extract intra-domain topologies from measurements results. In this paper, based on a large dataset collected with mrinfo, a multicast tool that silently discovers all interfaces of a router, we provide a mechanism for retrieving intra-domain topologies. The main challenge is to assign an AS number to a border router whose IP addresses are not mapped to the same AS. Our algorithm is based on probabilistic and empirical IP allocation rules. The goal of our pool of rules is to converge to a consistent router to AS mapping. We show that our router-to-AS algorithm results in a mapping in more than 99% of the cases. Furthermore, with mrinfo, point-to-point links between routers can be distinguished from multiple links attached to a switch, providing an accurate view of the collected topologies. Finally, we provide a set of large intra-domain topologies in various formats. [less ▲]

A real-time and interactive auralization system has been developed within the research project Auralias (www.auralias.be). Originally conceived for architectural acoustics applications, this system is now applied to auralize the effect of noise reduction solutions in industrial halls. Some specific characters of this kind of problems are first identified: several sources with intermittent noise emission, rectangular hall geometries, quite reverberant spaces, sound level calibration needed. A protocol for the application of the auralizer is then tested on an example, from the room acoustics model to the final sound rendering. [less ▲]

Pneumococcal infections are a major cause of morbidity and mortality among the elderly and high-risk groups. There is a concern about the expansion of pneumococcal drug resistance. A pneumococcal polysaccharide vaccine exists, which is epidemiologically adapted and has few side effects. The comparison of vaccine recommendations in six countries shows significant divergences. These can be explained by the few scientific evidence of the current vaccine efficacy. While awaiting a more effective vaccine, the current vaccine has a limited place in the strategies of preventive medicine. [less ▲]

European policies (European Framework Directive: Water 2000/60/CE, Directive 76/464/CE) impose to reduce the releases of about a hundred substances in surface water. In the last years, the AQUAPOLE has been involved in two studies related to this matter. First, on the request and with the financial support of both the French Ministry of Environment and ONEMA (“Office National de l’Eau et des Milieux Aquatiques”), INERIS (“Institut National de l’Environnement Industriel et des Risques”) drew up the guidelines of a methodology allowing fixing the local Limit Values to Emission so as to abide by the quality standards on the whole watershed. Within this context, INERIS wishes to test the use of pollutant transfer models on pilot sub-basins. The PEGASE model has been used to simulate micropollutants on two concrete use cases (1): (iii) in the Meuse sub-basin, managed by the French Water Agency Rhine-Meuse, for simulations concerning cadmium and zinc; (iv) in the Adour sub-basin, managed by the French Water Agency Adour-Garonne, for simulations applied to cadmium and copper. The choice of each substances and sub-basins was made by mutual agreement between INERIS, the concerned Water Agencies, and the AQUAPOLE. A major selection criterion for the substances and the sub-basins was the availability of data (sources and in situ measurements). For the second study, the PEGASE model has been adapted to describe the cocaine’s behaviour (using a stable metabolite of the cocaine in the environment: the benzoylecgonine (BZE)) in waste water, waste water treatment plants (WWTP) and surface water (2). The cocaine is newly described in the model as an additional micropollutant (PEGASE already treats numerous heavy metals), thanks to the implementation of new state variable equations and their specific parameterizations. Simulations of BZE have been done in the Walloon and Flemish regions, where many measurements from the COWAT project (3) were available. The first results are showing good agreement between calculated and measured values. The ability of the model to simulate the fate of studied micropollutants (cadmium, zinc, copper, and the cocaine derivatives) in surface waters should be enhanced and extended to other substances and basins. Moreover, additional data still have to be collected and measured. [less ▲]

This paper reports investigations carried out to determine the optimum culture conditions for the production of hydrogen with a recently isolated strain Clostridium butyricum CWBI1009. The production rates and yields were investigated at 30 °C in a 2.3 l bioreactor operated in batch and sequenced-batch mode using glucose and starch as substrates. In order to study the precise effect of a stable pH on hydrogen production, and the metabolite pathway involved, cultures were conducted with pH controlled at different levels ranging from 4.7 to 7.3 (maximum range of 0.15 pH unit around the pH level). For glucose the maximum yield (1.7 mol H2 mol-1 glucose) was measured when the pH was maintained at 5.2. The acetate and butyrate yields were 0.35 mol acetate mol-1 glucose and 0.6 mol butyrate mol-1 glucose. For starch a maximum yield of 2.0 mol H2 mol-1 hexose, and a maximum production rate of 15 mol H2 mol-1 hexose h-1 were obtained at pH 5.6 when the acetate and butyrate yields were 0.47 mol acetate mol-1 hexose and 0.67 mol butyrate mol-1 hexose.
