In order to handle future economic, social and environmental changes, the assessment, management and conservation of the local genetic resources of cash crop species is a fundamental requirement. We investigated the pattern of genetic and morphological diversity of Cananga odorata (Lam.) Hook f. & Thomson forma genuina, an important essential oil tree for the perfume industry in the introduction area of the western Indian Ocean islands. We sought to identify key elements for developing a conservation and management strategy for ylang-ylang genetic resources. Genetic and morphological variations were assessed using Amplified Fragments Length Polymorphism and morphometrics traits and information about farmers' practices were collected. The existence of substantial overall genetic diversity (HT = 0.2599) and the grouping of plantations into different genetic groups suggest that there have been a series of introduction events in the area, with limited exchanges of genetic material within and between islands, which is not what is suggested in the historical records. The morphological study revealed high phenotypic variability despite very similar agronomical practices throughout the studied area. The morphological and genetic variability might have been created and maintained without any planned or conscious management, and this has largely determined the genetic structuring in the area (11.74% genetic variation among islands and 20.68% among plantations). With this species, where past introduction events and farmers’ practices have shaped the genetic variation, on-farm preservation and the maintenance of the current management practices is recommended. Ex situ conservation efforts should also be undertaken, if economically affordable. [less ▲]

We numerically study the expansion dynamics of ultracold atoms in a one-dimensional disordered potential in the presence of a weak position measurement of the atoms. We specifically consider this position measurement to be realized by a combination of an external laser and a periodic array of optical microcavities along a waveguide. The position information is acquired through the scattering of a near-resonant laser photon into a specific eigenmode of one of the cavities. The time evolution of the atomic density in the presence of this light-scattering mechanism is described within a Lindblad master equation approach, which is numerically implemented using the Monte Carlo wave function technique. We find that an arbitrarily weak rate of photon emission leads to a breakdown of Anderson localization of the atoms. [less ▲]

Objectif : Etudier l’expression de KISS1 (métastatine) et de son récepteur KISS1R lors de la grossesse normale et pathologique. Matériels et méthodes : Nous avons étudié la localisation de KISS1 et KISS1R par immunohistochimie dans des placentas normaux (1 er et 3 ème trimestre). Par RT-PCR quantitative, nous avons évalué le niveau d’expression des ARNm dans les placentas et les lits placentaires correspondants. Les niveaux d’expression de ARNm ont été comparés entre les grossesses normales (GN, n=13) et les grossesses spathologiques Prééclampsiques -PE-, n=17 et retard de croissance intrautérine -RCIU-, n=9). Résultats : Au premier trimestre des GN, KISS1 est majoritairement localisé dans les syncitiotrophoblastes, alors que KISS1R est détecté dans le mesenchyme villositaire. Au cours du troisième trimestre, KISS1 est uniquement localisé dans le syncitiotrophoblaste au contact avec la décidue et dans le mésenchyme villositaire et KISS1R est détecté dans le trophoblaste extra-villeux ainsi que dans quelques cellules de la décidue. Les analyses par RT-PCR mettent en évidence une expression plus importante des ARNm de KISS1 (p<0,001) et de KISS1R (p=0.039) dans les placentas (GN,PE et RCIU) par rapport aux lits placentaires correspondants. Les niveaux d’expression de KISS1 et KISS1R ne sont pas, cependant, significativement modulés dans les grossesses pathologiques. Conclusions : Par immunohistochimie, nos résultats indiquent une expression spatiotemporelle différente pour KISS1 et KISS1R entre le 1 er et 3 ème trimestre des grossesses normales. Nous n’avons pas mis en évidence de modulation de l’expression des ARNm dans les grossesses pathologiques. [less ▲]

Bulk (RE)BCO materials can be used potentially as powerful permanent magnets. The magnetic field distribution around a bulk HTS magnet, however, is strongly non-uniform (conic profile predicted by the Bean model) compared to the rather flatter distribution around a ferromagnet. In the present work, we study how FeNi soft ferromagnetic alloys of different shapes can be combined with (RE)BCO bulk superconductors to improve the distribution of trapped field or its average value at the surface of the bulk sample. The FeNi ferromagnetic alloys are machined into pieces of various shapes (e.g. cylinder, cone) attached to the bottom surface of the bulk HTS disks. The magnetic properties of each ferromagnetic/superconductor (F/S) assembly are measured under axial magnetic field at 77 K. Small coils and Hall probe mappings provide the average magnetization and field distribution respectively. The results are compared to the intrinsic magnetic hysteresis curves of the magnetic alloys and of the superconductor. Measurements of the average magnetization show that the effects of the ferromagnetic alloys depend mainly on the volume of the ferromagnet and add up to the effect of the superconductor. However, at constant ferromagnetic volume, the shape of the ferromagnetic piece is found to influence the magnetic field penetration and distribution against the top surface of the superconductor.

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 ▲]

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 ▲]

The aim of the present study is to compare the effect of different steam explosion treatments on physicochemical properties and hydrolysis rate of a pure bleached cellulose. The results showed that moderate steam explosion treatments (severity factor below 5.2) did not improve the enzymatic hydrolysis rate of the cellulose fibers. The characterization of the obtained samples showed an increase of the cellulose accessibility coupled with an increase of the overall crystallinity of the substrate. In these conditions, the higher accessibility is counterbalanced by the increased crystallinity. Indeed, a greater proportion of the substrat is accessible by only a fraction of the enzymatic complex (exo-glucanases) activities. When the severity factor reached 5.2, a decrease of the cellulose enzymatic hydrolysis rate was observed. In this case, TGA analysis showed an increase of the char level at the end of the pyrolysis which traduced an important thermal degradation of the samples. The thermal degradation of cellulose lead to an important change in substrate composition, which induced a decrease of the cellulose ratio available for hydrolysis and caused a decrease of the hydrolysis yields.

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.
