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).

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 ▲]

Ce livre s’adresse plus particulièrement aux commerçants «indépendants», débutants ou confirmés. Il concerne autant ceux qui envisagent de lancer une nouvelle activité commerciale en ligne que ceux qui souhaiteraient positionner leur business actuel également en ligne. Il fait le point sur le "commerce connecté" et sur les bonnes pratiques de mise en place d’une stratégie en la matière. Si la volonté affichée est d’inciter à entreprendre une activité commerciale en ligne, il serait trompeur de faire croire qu’il s’agit d’un eldorado. Cet ouvrage se veut donc réaliste en livrant l’état de l’art, avec des recommandations concrètes pour maximaliser les chances de réussite et éviter les écueils les plus fréquemment observés.

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.

There are currently only six known high mass X-­‐ray binaries (HMXBs) that also exhibit MeV, GeV, and/or TeV emission ("gamma-­‐ray binaries"). Expanding the sample of gamma-­‐ray binaries and identifying unknown Fermi sources are currently of great interest to the community. Based upon their positional coincidence with the unidentified Fermi sources 1FGL J1127.7-­‐6244c and 1FGL J1808.5-­‐1954c, the Be stars HD 99771 and HD 165783 have been proposed as gamma-­‐ray binary candidates. During Fermi Cycle 4, we have performed multiwavelength observations of these sources using XMM-­‐Newton and the CTIO 1.5m telescope. We do not confirm high energy emission from the Be stars. Here we examine other X-­‐ray sources in the X-­‐ray sources in the field of view that are potential counterparts to the Fermi sources. [less ▲]

Introduction : Le projet TADAM, une étude contrôlée randomisée, comparait un nouveau traitement assisté par héroïne avec des traitements existants par méthadone à Liège, en Belgique. Nous avons réalisé une étude qualitative sur l'attitude des personnes dépendantes de l'héroïne envers ce type de projet, ainsi que sur l'attitude des intervenants d'institutions de soins travaillant avec ces personnes Méthode : Avant qu'un patient ne soit inclus dans le projet TADAM, il lui était demandé d'expliquer pourquoi il souhaitait rentrer en traitement (n=80). Des interviews ont également été réalisées auprès de consommateurs d'héroïne non inclus dans le projet, avant la période d'inclusion (n=65), au milieu de celle-ci (n=30) et dans ses derniers mois (n=23). Pendant le projet, des interviews ont également été réalisées auprès d'intervenants travaillant dans des institutions de soins pour personnes dépendantes de substances, soit de manière individuelle (n=10), soit en groupe (n=6) pour connaître leur attitude face au projet TADAM. Résultats : De nombreux patients souhaitaient rentrer dans ce projet pour améliorer leurs conditions de vie. La raison principale de ne pas rentrer dans ce type de traitement était la peur de devenir plus dépendant. Cette raison était renforcée par le fait que le traitement par héroïne proposé ne durait que 12 mois et les patients s'inquiétaient de leur situation après ce traitement : ils avaient peur d'être plus dépendants et donc dans une situation plus difficile qu'avant le traitement. L'attitude des intervenants étaient plutôt favorable mais prudente. Conclusion : Contrairement aux craintes préalables, les usagers d'héroïne ne se précipitent pas en masse et sans réfléchir vers un traitement assisté par héroïne. Certains réfléchissent longtemps avant de s'y engager. Une information précise et un traitement sans durée minimum sont nécessaires. [less ▲]

The gonadosomatic index at spawning, absolute fecundity, and egg size for the female sexual products as well as the density and consistency of semen for the male sexual products were examined in cultured Abramis brama 9 Blicca bjoerkna F1 hybrids and compared with the parental species at their first sexual maturity. Females ovulated under environmental conditions, and their eggs were weighed, counted and measured. Semen of males was macroscopically examined and spermatozoa counted using a hemocytometer. Results revealed that hybridization affected the quality of female and male gametes but with an overlap between hybrids and parents. The gonadosomatic index and fecundity were significantly lower than those of parental species. Egg sizes in hybrids showed a parental effect but to the benefit of hybrids. Semen of hybrids was more diluted which was classified into two groups: the white semen overlapping slightly with parents and the aqueous without any overlap with parents. Overlapped areas between hybrids and parents in term of quality of sexual products could translate that females and males of these hybrids have the biological capacity to produce high quality gametes and thus, a greater chance to produce F2 and backcross generations in rivers.

The EUV high resolution imager (HRI) channel of the Extreme Ultraviolet Imager (EUI) on-board Solar Orbiter will observe the solar atmospheric layers at 17.4 nm wavelength with a 200 km resolution. The HRI channel is based on a compact two mirrors off-axis design. The spectral selection is obtained by a multilayer coating deposited on the mirrors and by redundant Aluminum filters rejecting the visible and infrared light. The detector is a 2k x 2k array back-thinned silicon CMOS-APS with 10 µm pixel pitch, sensitive in the EUV wavelength range. Due to the instrument compactness and the constraints on the optical design, the channel performance is very sensitive to the manufacturing, alignments and settling errors. A trade-off between two optical layouts was therefore performed to select the final optical design and to improve the mirror mounts. The effect of diffraction by the filter mesh support and by the mirror diffusion has been included in the overall error budget. Manufacturing of mirror and mounts has started and will result in thermo-mechanical validation on the EUI instrument structural and thermal model (STM). Because of the limited channel entrance aperture and consequently the low input flux, the channel performance also relies on the detector EUV sensitivity, readout noise and dynamic range. Based on the characterization of a CMOS-APS back-side detector prototype, showing promising results, the EUI detector has been specified and is under development. These detectors will undergo a qualification program before being tested and integrated on the EUI instrument. [less ▲]

We present here the results obtained during our tentative to analyse quantitatively dried drops of phospholipidic solutions by Raman spectroscopy. Drops of different solutions of phospholipid were deposed onto different material supports. The spots were then analyses by confocal Raman microspectroscopy. Experimental settings have been optimised and the analysis of the intensity profile of the Raman signal inside the spot allows the establishment of a calibration curve for the determination of the phospholipids amount within a 1 µL solution.

This paper presents the design, fabrication and preliminary characterization of highly sensitive MEMS-based Xylophone Bar Magnetometers (XBMs) realized in imec’s poly-SiGe MEMS technology. Key for our Lorentz force driven capacitively sensed resonant sensor are the combination of reasonably high Q-factor and conductivity of imec’s poly-SiGe, our optimized multiphysics sensor design targeting the maximization of the Q-factor in a wide temperature range as well as our proprietary monolithic above-CMOS integration and packaging schemes. Prototypes 3-axis devices were fabricated and characterized. We present optical vibrometer and electrical S-parameter measurements of XBMs performed in vacuum with a reference magnet at increasing sensor separation. The optical oscillation amplitude is well correlated with the magnetic field amplitude. The electrical 2-port measurements, 1st port as Lorentz force actuator and 2nd port as capacitive sensor, also reproduces the designed magnetic field dependence. This opens the way towards the on-chip integration of small footprint extremely sensitive magnetometers. [less ▲]

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.
