Background : TADAM est une étude contrôlée randomisée comparant un traitement par héroïne (HAT) avec des traitements par méthadone existants. Ce projet est toujours en cours mais nous disposons déjà de données sur les patients au moment de leur inclusion. Nous analysons leur profil, particulièrement leurs caractéristiques criminologiques, et nous le comparons avec celui des participants aux autres expériences HAT. Méthodologie : Lors de l’inclusion, chaque patient a répondu à des questionnaires standardisés ainsi qu’à un questionnaire de délinquance et de victimisation auto-rapportées. Comme point de comparaison, nous avons sélectionné trois études européennes contrôlées randomisées sur le HAT. Nous avons ajouté une étude suisse, sans groupe contrôle, évaluant les effets de la prescription d’héroïne sur la délinquance des patients. Résultats : Nos patients sont plus âgés et plus souvent de sexe masculin. Ils bénéficient plus souvent d’allocations sociales et ont connu plus de traitements pour un problème d'addiction. Ces patients avaient un passé judiciaire aussi important qu’à l’étranger. Sur les six derniers mois, ils sont moins nombreux à avoir commis des actes délinquants mais le nombre d'actes commis est plus important. Les faits sont surtout liés à la drogue ou à la propriété. Conclusion : Nos patients étaient moins nombreux à être délinquants mais il y aurait plus de professionnalisation qu'à l'étranger. Le plus petit nombre de délinquants pourrait s'expliquer par la moyenne d'âge plus élevée de nos patients, la plus grande proportion d'allocataires sociaux ou encore par le recours plus important à des traitements pour leur(s) addiction(s).

The paper proposes an equilibrium asset pricing model that accounts of the incomplete information on returns distribution and investors' preferences. Only moments up to order four of unknown unconditional distribution can be observed, and the model does not impose that portfolio diversi fication or moments preference should hold. Using Chebyshev-type of inequalities, an intuitive risk measure (risk horizon) is introduced with reference to the speed of convergence of a security's mean return to its expectations. By an arbitrage argument, this risk measure is related to the horizon of treasury securities in a system of equations that allows the calibration of the model parameters using term structure information. In particular, the expected return on the market portfolio can be endogenously estimated inside this system. The model calibration on U.S. market data provides plausible parameters estimates and interesting cyclical patterns in the time series of the expected return. The empirical relevance of these estimates is examined with tests of statistical and economic predictive ability for stock excess returns. The results provide signi ficant evidence on the added value of the estimates when compared to popular predictors found in the literature (see a.o. Lettau and Ludvigson, 2001; Rapach and Wohar, 2006; Goyal and Welch, 2008). [less ▲]

Several initiatives intended to highlight the geological heritage have been recently developed in the Liège province (Belgium). The Ampsin and Tchafornis (Engis) geosites rank among them. The Ampsin geosite shows the clear-cut passage between the shallow carbonate facies of the Middle Viséan and the terrigenous detrital facies of the Namurian. The Tchafornis geosite gives the opportunity to observe a superb example of biostrome with large colonial rugose corals of the base of the Upper Frasnian (Upper Devonian). Both are located in disused quarries and also give prominence to the regional extractive industry. [less ▲]

Asperity flattening has a huge influence on friction and wear in metal forming processes. Nevertheless, phenomena that occur at the microscopic scale are still not well understood. Since no experiment can be easily performed in real forming conditions, numerical models are essential to achieve a better knowledge of what happens in these contact regions. In this paper, a threedimensional model of a rough strip flattened by a rigid rough tool is presented. The boundary conditions applied to this model correspond to the ones encountered in a real cold-rolling case. The results are compared to experimental measurements from the pilot mill of ArcelorMittal Maizières R&D. [less ▲]

Due to the large number of applications of bisphenol-A (BPA), the human exposure routes are multiple. We aimed to review shortly the food and non-food sources of BPA, and to evaluate their contribution to the human exposure. Food sources discussed here include epoxy resins, polycarbonate and other applications, such as paperboard and polyvinylchloride materials. Among the non-food sources, exposures through dust, thermal paper, dental materials, and medical devices were summarized. Based on the available data for these exposure sources, it was concluded that the exposure to BPA from non-food sources is generally lower than that from exposure from food by at least one order of magnitude for most studied subgroups. The use of urinary concentrations from biomonitoring studies was evaluated and the back-calculation of BPA intake seems reliable for the overall exposure assessment. In general, the total exposure to BPA is several orders of magnitude lower than the current tolerable daily intake of 50 mug/kg bw/day. Finally, the paper concludes with some critical remarks and recommendations on future human exposure studies to BPA. [less ▲]

GC/MS (Gas Chromatography coupled to Mass Spectrometry) is the analytical method of choice for carboxylic acids analysis because of good sensitivity, low limit of detection and the possibility to compare the pattern of fragmentation with existing databases for identification. However GC requires that the analytes are volatile. If it is not the case, the use of chemicals in order to perform the derivatization is mandatory, this may induce analytical bias. CE (Capillary electrophoresis) is a technique of choice for ions separation without prior treatments. The method is fast and do not require highly technical skills. A UV detector is the most common detection method; however electrospray mass spectrometry detection is recently gaining interest, while it really helps for structural information of the detected compounds. In this poster, the preliminary results of CE/MS analysis of several carboxylic acids are presented. All carboxylic acids are analyzed without any sample pretreatment. These acids looked at are from the “Citric Acid Cycle” including pyruvate and some isotope labeled analogues but also glyoxylate, lactate, oxalate and tartrate. Moreover, the preliminary results of a sample preparation approach to remove phosphate salts are presented. Phosphate is a very common salt that is often used in biological buffers but prevents the derivatization of carboxylic acid for GC/MS analysis and reduces the reproducibility of results for both GC/MS and CE/MS analysis.

Little by little, nanotechnology has emerged amid enormous anticipations and fantastic promises of new materials, aspiring to manipulate our world “atom by atom.” While these grand visions continue to capture the imaginations of various audiences—and continue to be contested, as well—nanotechnology has developed into more than that. During the last two decades, many research programs and industrial R&D expenditures have resulted in actual products and tangible innovations. Nanotechnology, it seems, is expanding. But what does it mean to say that nanotechnology is expanding? [less ▲]

Gallery excavation in clayey rocks induces stress perturbations that trigger damage propagation. The excavation process creates then the so-called excavation damaged zone in which properties are modified. The prediction of the extension and especially of the fracturing structure in this zone remains a crucial issue in the context of underground storage. Since strain localization in shear band mode is frequently observed in experimental works, the excavation damaged zone can be modeled by considering the development of strain localization bands. A hydro-mechanical modelling of a gallery excavation is performed. The numerical results exhibit an excavation damaged zone extension similar to the in situ measurements and provides information about the rock state within this zone. [less ▲]

Relevance: LBP is common among tennis players. More than one third of professional tennis players reported LBP as reason for missing at least one tournament. As impaired lumbar motor functions have been associated with LBP, it appears particularly relevant to assess lumbopelvic movement control in tennis players. Methods: Twenty amateur tennis players (male, 22.9 ± 3.0 years) were included. Subjects were pooled into two groups: 10 players with chronic LBP (mean pain duration: 3.1 ± 2.6 years, pain severity score: 3.5/10 on a pain visual analogue scale) and 10 players without LBP. The Bent Knee Fall Out (BKFO) test was used to assess the players’ ability to control movement of lumbopelvic region. BKFO was performed in supine position and monitored by means of two pressure biofeedback units inflated to 40 mmHg and positioned under the lumbar spine of the participant. The reliability of this test has been previously assessed. Players were instructed to make an active abduction-external rotation movement of the hip (45°) without concomitant lumbopelvic movement of the pelvis and low back. Pressure modification (mmHg) was recorded, each side was assessed. Results: Tennis players with LBP had a worse lumbopelvic movement control than players without LBP both for dominant (9.0 mm Hg vs 3.4 mmHg, P<0.05) as well for the non-dominant side (9.1 mmHg vs 4.6 mmHg, P<0.05). Conclusions: Tennis players with LBP experience similar alterations of motor control as those observed in sedentary people with LBP. However, it remains unclear if these alterations are the cause of the consequence of chronic LBP. Implications: Further prospective studies should assess the cause or effect relationship and should determine whether motor control exercises are effective in tennis players with chronic LBP.

Although karstic weathering (sensu lato) is a major concern for the exploitation of limestone quarries, the importance, spatial extension, and intensity of this natural phenomenon are rarely investigated because of the lack of applicable technique to assess these variables other than subsurface geophysical exploration methods. Here, we propose to use the intrinsic property of ghost-rock weathering, tectonic control, to predict the degree and type of weathering of the reserve of two contiguous limestone quarries in the Tournai area (western Belgium). First, we revised the macrotectonic setting of these quarries, creating five tectonic entities. Then, we built an extensive fracture database (1357 ‘events’), recording fracture direction, dip, width, height, mineralization, and weathering. Then, we calculated a “Sterile Index” that is a simple function of the relative occurrence and mean width of karstified fractures. The rose diagrams of fracture orientations are contrasted between tectonic entities and so are the intensity and the dominant type of weathering: tectonic entities with widely dispersed fracture directions are significantly more weathered than entities with narrowly dispersed rose diagrams. Preliminary tests indicate fracture orientation and weathering are consistent within the tectonic entities, allowing extrapolation to quarries reserves. Ultimately, this technique can be used to predict the rock waste volume of the quarries reserves (when combined with geophysical exploration methods) and manage the development of the quarries accordingly.
