[more ▼] A new generation of photobioreactors for the clean production of green biofuels is described. It is based on the smart combination of living and inanimate, namely microalgae encapsulated in porous silica gels. Such hybrid materials would allow for the controlled exploitation of photosynthesis to assimilate atmospheric CO2 and convert it into useful energy sources by using sunlight. The use of biocompatible routes for the immobilization of cyanobacteria has extended the duration of survival up to 40 weeks.

[more ▼] OBJECTIVES: Use functional brain imaging to explore activity changes in centres involved in trigeminal pain processing and control before and after occipital neurostimulation in drug-resistant chronic cluster headache patients. BACKGROUND: Occipital nerve stimulation (ONS) provides relief to about 60% of patients suffering from drug-resistant chronic cluster headache (drCCH). Its mode of action, however, remains elusive, but the long latency to meaningful effect suggests that ONS induces slow neuromodulation. METHODS: Ten drCCH patients underwent an 18FDG-PET scan after ONS durations varying between 0 and 30 months. All were scanned with ongoing ONS (ON) and with the stimulator switched OFF. RESULTS: After 6-30 months of ONS, 3 patients were pain free and 4 had a ≥ 90% reduction of attack frequency (responders). In patients overall compared to controls, several areas of the pain matrix were hypermetabolic: ipsilateral hypothalamus, midbrain and ipsilateral lower pons. All normalized after ONS, except the hypothalamus. Switching ON or OFF the stimulator had little influence on brain glucose metabolism. The perigenual anterior cingulate cortex (PACC) was hyperactive in ONS responders compared to non-responders. INTERPRETATION AND CONCLUSIONS: Metabolic normalization in the pain neuromatrix and lack of short-term changes induced by the stimulation support the hypothesis that ONS acts in drCCH through slow neuromodulatory processes. Selective activation in responders of PACC, a pivotal structure in the endogenous opioid system, suggests that ONS may restore balance within dysfunctioning pain control centres. That ONS is nothing but a symptomatic treatment might be illustrated by the persistent hypothalamic hypermetabolism which could explain why autonomic attacks may persist despite pain relief and why cluster attacks recur shortly after stimulator arrest.

[more ▼] Background. Drug-resistant chronic cluster headache (drCCH) is a devastating condition for which various invasive procedures have been tempted without any satisfactory effect. Our prospective pilot study of great occipital nerve stimulation (ONS) in 8 drCCH patients showed encouraging results at 15 months (1). Methods. We recruited 15 patients with drCCH according to the previously published criteria of intractability (2). They were implanted with suboccipital stimulators on the side of their headache. Long-term follow-up was achieved by questionnaires administered during a headache consultation and/or by telephone interviews. Results. One patient had an immediate post operative infection of the material. Mean time with ONS was 28.8 months (range 3-60 months). Nine of the 14 remaining patients were totally pain-free (64%), 2 patients had an improvement in frequency exceeding 90% and one patient a 89% amelioration. Two patients did not respond or described mild improvement. Intensity of residual attacks was not improved by ONS. Four patients (29%) were able to reduce their prophylaxis. Common technical problems were battery depletion (N=8/14, 57%) and material infection (N=3/15, 20%). Recurrent battery replacement (until 2/ year in one patient) is now avoided by the availability of rechargeable batteries. Clinical peculiarities associated with ONS were occurrence of infrequent contralateral attacks (N=5/14, 36%), and/or isolated ispilateral autonomic attacks (N=5/14, 36%). Rapid attack recurrence after stimulator switch off was reported by 7/12 improved patients (58%). Two patients found ONS-related paresthesias unbearable; one had his stimulator removed, the other switched it off though he was objectively ameliorated. Subjectively, nine patients are very satisfied by ONS and one patient moderately satisfied. Conclusions. Our long-term follow-up confirms the efficacy of ONS in drCCH, which remains a safe and well-tolerated technique. The occurrence of contralateral attacks and isolated autonomic attacks in nearly 50% of ONS responders may have therapeutic and pathophysiological implications.

[more ▼] The Extreme Ultraviolet Imager (EUI) onboard Solar Orbiter consists of a suite of two high-resolution imagers (HRI) and one dual-band full Sun imager (FSI) that will provide EUV and Lyman-α images of the solar atmospheric layers above the photosphere. The EUI instrument is based on a set of challenging new technologies allowing to reach the scientific objectives and to cope with the hard space environment of the Solar Orbiter mission. The mechanical concept of the EUI instrument is based on a common structure supporting the HRI and FSI channels, and a separated electronic box. A heat rejection baffle system is used to reduce the Sun heat load and provide a first protection level against the solar disk straylight. The spectral bands are selected by thin filters and multilayer mirror coatings. The detectors are 10µm pitch back illuminated CMOS Active Pixel Sensors (APS), best suited for the EUI science requirements and radiation hardness. This paper presents the EUI instrument concept and its major sub-systems. The current developments of the instrument technologies are also summarized.

[more ▼] The aim of the present study was to assess the occurence of an own-age bias on age estimation performance (better performance for faces from the same age range as that of the beholder) by using an experimental design inspired from research on the own-race effect. The age of participants (10 to 14 year old children and 20 to 30 year old adults) was an independent factor that was crossed with the age of the stimuli (faces of 10 to 14 year old children and faces of 20 to 30 year old adults), the dependent measure being the accuracy of age estimation. There were 30 participants in each age group. An interaction between the two factors was expected. A two-way 2 (age of the participants)x 2 (age of the stimuli) ANOVA with repeated measures on the last factor was carried out on the accuracy scores. This analysis revealed a main effect of age of participants and of age of stimuli, and an interaction between these two factors. Children's performance was less accurate when estimating the age of adults' faces compared with children's faces. However, in both age groups, accuracy was better for children's faces than for adults' faces.

[more ▼] We consider the move generation in a modern board game where the set of all the possible moves is too large to be generated. The idea is to provide a set of simple abstract tactics that would allow enough combinations to provide strong opposition. The reduced search space is then traversed using the alpha beta search. We also propose a technique that allows us to remove the stochasticity from the search space. The model was tested in a game called Axis and Allies: a modern, turn-based, perfect information, non-deterministic, strategy board game. We first show that a tree search technique based on a restrained set of moves can beat the actual scripted AI engine --- E.Z. Fodder. We can conclude from the experiments that searching deeper generates complex maneuvers which in turn significantly increase the likelihood of victory.

[more ▼] The trapped magnetic field is examined in bulk high-temperature superconductors that are artificially drilled along their c-axis. The influence of the hole pattern on the magnetization is studied and compared by means of numerical models and Hall probe mapping techniques. To this aim, we consider two bulk YBCO samples with a rectangular cross-section that are drilled each by six holes arranged either on a rectangular lattice (sample I) or on a centered rectangular lattice (sample II). For the numerical analysis, three different models are considered for calculating the trapped flux: (i), a two-dimensional (2D) Bean model neglecting demagnetizing effects and flux creep, (ii), a 2D finite-element model neglecting demagnetizing effects but incorporating magnetic relaxation in the form of an E – J power law, and, (iii), a 3D finite element analysis that takes into account both the finite height of the sample and flux creep effects. For the experimental analysis, the trapped magnetic flux density is measured above the sample surface by Hall probe mapping performed before and after the drilling process. The maximum trapped flux density in the drilled samples is found to be smaller than that in the plain samples. The smallest magnetization drop is found for sample II, with the centered rectangular lattice. This result is confirmed by the numerical models. In each sample, the relative drops that are calculated independently with the three different models are in good agreement. As observed experimentally, the magnetization drop calculated in the sample II is the smallest one and its relative value is comparable to the measured one. By contrast, the measured magnetization drop in sample (1) is much larger than that predicted by the simulations, most likely because of a change of the microstructure during the drilling process.

Their catalytic performances were compared to those of bulk HPAs in the propylene oxidation by molecular oxygen at 350°C. The supported HPAs exhibit higher catalytic activity in propylene oxidation than the bulk ones and favoured the formation of acrolein, acetaldehyde and acetic acid, compared to the mother catalysts which lead only to the formation of COx. The enhanced oxidation catalytic activity of supported systems was attributed to the fine dispersion of H 3+xPMo 12-xVxO 40 species on the CMI-1 mesoporous material via physical adsorption, together with the fact that the structure of both CMI-1 and HPAs remained intact during the impregnation. © 2010 Elsevier B.V.

This marker has been proposed for urinary measurement. However, in the literature, authors indistinctly use "absolute" value or NGAL to creatinine ratio. Up to now, there are no strong arguments favouring for one. This question is of importance as this marker is sensed to be used only on urine random samples. To find an answer to this very practical matter, one approach could be to compare biological CV(intra-individual variation) of the "absolute" and ratio results.

The analysis shows that not unlike a “Swiss knife”, sector inquiries constitute a convenient, multifunctional tool, which serves a variety of purposes. Sector inquiries indeed entitle the Commission to (i) lower the minimal procedural requirements which must be met to launch investigations; (ii) extend the substantive scope of its inquiries beyond mere infringements to Article 101 and 102 TFEU; and (iii) incentivize firms to spontaneously comply with the antitrust rules. In light, however, of a number of shortcomings arising from the Commission’s sector inquiries’ practice, this article formulates several “best practices” (which are also relevant for other competition authorities with similar powers).

[more ▼] Recent development of equations based on mid-infrared (MIR) spectrometry for the prediction of milk fatty acid (FA) contents allows their measurement on a large scale during performance recording. The objective was to show that a genetic evaluation for milk FA in dairy cattle is feasible in the Walloon region of Belgium and to report first results. Estimated breeding values (EBV) and associated reliabilities (REL) were computed using a multi-trait test-day animal model similar to the one used for the routine genetic evaluation for yield traits. Studied traits were first lactation test-day milk, fat and protein yields, fat (FAT) and protein contents, and content of saturated fatty acids in milk (g/100g of milk, SAT). More than 6,700,000 records were available for common production and content traits and 194,000 records were used for SAT. Used variance components were estimated using REML. The average SAT content was 2.79% with a standard deviation (SD) of 0.50%. A total of 1,707 Holstein bulls used in Walloon Region had REL superior to 0.49 for all studied traits. REL for SAT ranged from 0.53 to 0.99. A total of 1,217 bulls had REL superior to 0.74. SD of EBV for SAT was 0.20%. The maximum and minimum SAT EBV values were 0.89% and -0.69%, respectively. In order to have a direct measure of the part of FAT that is not due to SAT, a new trait (dSAT) was post-evaluated and defined as difference between expected SAT EBV for a given FAT EBV and the estimated EBV for SAT. This new trait can be assumed to be a direct predictor of the content of unsaturated fatty acids in fat. The interest is that this trait cannot be accurately predicted directly by MIR. The maximum and minimum EBV for dSAT for the 1,707 bulls were -0.28% and 0.24%, respectively. Based on these results, a genetic evaluation for milk fatty acids is feasible. In the bull population used recently, a genetic variability for dSAT exists and could be used to improve the milk fat composition.

The problem of deciding whether an automatic sequence is ultimately weakly R-periodic is also shown to be decidable.

We propose a framework to assess the robustness of such an ICS in the presence of churn, and evaluate two models for handling churn. The key idea is to reactively recover lost neighbours, either by picking new nodes at random, or by selecting a new one among the node’s two-hop neighbours, while maintaining high reliability and low communication overhead. We then show by simulations that our models mitigate the impact of churn, and lead to a good accuracy com- pared to an instance of an ICS running without churn.

[more ▼] A cardiovascular and circulatory system (CVS) model has been validated in silico, and in several animal model studies. It accounts for valve dynamics by means of Heaviside function to simulate “open on pressure, close on flow” law. Thus, it does not consider the real time scale of the valve aperture and thus doesn’t fully capture valve dysfunction. This work describes a new coupled model of the cardiovascular system that accounts for progressive mitral valve aperture. Simulations show good correlation with physiologically expected results for healthy or diseased valves. The large number of valve model parameters indicates a need for emerging, lighter and minimal mitral valve models that are readily identifiable to achieve full benefit in real-time use. These results suggest a further use of this model to track, diagnose and control valves pathologies.

[more ▼] Introduction : Depuis une vingtaine d’années, le développement des activités sportives s’accompagne d’une incidence accrue de diverses tendinopathies, souvent rebelles aux traitements conservateurs classiques (anti-inflammatoires non stéroïdiens, orthèses, kinésithérapie, infiltrations…). De nouvelles thérapeutiques, dont l’injection de concentrés plaquettaires (plasma riche en plaquettes ou PRP), sont actuellement en cours d’évaluation clinique. Objectifs : L’injection de PRP fait actuellement l’objet de recherche comme thérapeutique des tendinopathies chroniques. L’injection intra-tendineuse nécessite idéalement un volume minimal afin de diminuer la pression lors de l’injection et minimiser les douleurs, mais il doit également présenter une concentration plaquettaire élevée ; par ailleurs, la quantité de facteurs de croissance libérés pourrait être liée au système de préparation. Méthodes : Après avoir prélevés divers échantillons de sang veineux chez 5 patients, nous avons comparé 5 techniques de préparation du PRP : celle du Service d’Hématologie Biologique du CHU de Liège, le PRP Kit de Curasan®, les techniques Plateltex®, GPS®II et RegenLab®. Résultats : Les différentes techniques permettent d’obtenir des concentrations plaquettaires plus importantes que dans le sang avec des volumes variables (de 0,3 mL à 6 mL) et un nombre de globules rouges et globules blancs limité (sauf pour GPS® II). Le nombre de plaquettes/µL apparaît plus élevé avec la technique Plateltex® et obtient le plus petit volume à injecter. Les autres techniques permettent également d’obtenir de petits volumes sauf avec le GPS®II. Le nombre de plaquettes collectées dans le PRP apparaît donc plus élevé avec cette technique mais avec une concentration faible. Discussion – Conclusion : La technique décrite par Plateltex® permet de recueillir le PRP le plus concentré dans le volume le plus faible.

Certains travaux, essentiellement in vitro, soulignent les potentialités réparatrices des plaquettes qui présentent la capacité d’accélérer la cicatrisation de différents tissus : os, muscles et tendons. Objectifs : Le but de notre étude préliminaire est d’objectiver l’effet « accélérateur » sur la réparation tendineuse suite à l’emploi d’injection de plasma enrichi en plaquettes (platelet-rich plasma ou PRP) car cette technique pourrait représenter une thérapeutique d’avenir en médecine physique et en traumatologie du sport. Méthodes : Nous avons sectionné et réalisé un défect de 5mm dans le tendon d’Achille de rats (N = 12). Quatre rats ont bénéficié d’une injection in loco de PRP et remis en liberté comme les autres dans leur cage. Trois rats (2 sans PRP et 1 avec PRP) sont euthanasiés à J5, J10, J20 et J30 et le tendon d’Achille en cours de régénération est disséqué et prélevé. Une étude biomécanique de traction jusqu’à rupture est réalisé à l’aide de « Cryo-jaw ». Résultats : L’analyse des résultats montre que la force développée pour obtenir la rupture tendineuse doit être plus importante pour les tendons ayant bénéficié d’une injection de PRP et ce dès J5. Discussion – Conclusion : Cette série préliminaire permet de montrer que les injections de PRP permettent une accélération de la cicatrisation tendineuse et une augmentation des valeurs de résistances à la traction.

[more ▼] Since the early nineties it is accepted that the excitation mechanism of B-type pulsators on the main sequence is due to the opacity peak in the iron-group elements at T~200,000 K. The Fe content plays then a major role in the excitation of β Cep and SPB pulsations. While theoretical non-adiabatic computations predict no β Cep pulsators and only a small number of SPBs for low metallicity environments such as that of the Magellanic Clouds (MCs), recent variability surveys of B stars in the SMC have reported the detection of a significant number of SPB and β Cep candidates. Since the SMC is the metal poorest (Z~0001-0.004) of the MCs, it constitutes an interesting object for investigating the disagreement between theory and observations. We approach the problem by calling into question some of the hypotheses made in previous studies: given the different chemical evolution of the SMC compared with our local galactic environment, is it appropriate to describe the chemical composition of SMC B stars by scaling the solar mixture to lower Z? Is that composition uniform in space and time? In this paper we present the results of a stability analysis of B-type stellar models computed with a revised chemical composition and metallicity specific to the SMC.

[more ▼] Comets had formed from dust and icy materials in the solar nebula 4.6 Gyrs ago. The cometary materials are considered as the most pristine in the solar system and both dust grains and icy materials in comets have been used to investigate the formation conditions of the solar system. One of interesting primordial characters is a nuclear spin temperature (related to an ortho-to-para ratio; OPR) of cometary molecules such as H2O, NH3, etc. The nuclear spin temperatures probably reflect the molecular formation temperatures in the solar nebula (or in the presolar molecular cloud). In this work, we analyzed high dispersion optical spectra of C/2001 Q4 (NEAT), C/2000 WM1 (LINEAR), 88P/Howell, fragments B and C of 73P/Schwassmann-Wachmann 3 and 8P/Tuttle. Our observations were performed by the Ultraviolet and Visual Echelle Spectrograph (UVES) mounted on the Very Large Telescope (VLT) in Chile and the High Dispersion Spectrograph (HDS) mounted on the Subaru telescope in Hawaii. We determined nuclear spin temperatures of NH3 in five comets based on optical spectra of NH2. The nuclear spin temperatures of NH3 can be obtained from OPRs of NH2. We used the (0,9,0) ro-vibronic band at 610nm in this work. Absorption lines (by the telluric atmosphere) and cometary C2 emission lines blended with NH2 emission lines were also taken into account in our analysis. These lines have never been considered in previous studies. The origin of icy materials in the five comets will be discussed based on these results.

[more ▼] Hot subdwarf stars, including helium core burning subdwarf B (sdB) stars and more evolved subdwarf O (sdO) stars, host three classes of nonradial pulsators. Two of them show rapid acoustic mode oscillations (with periods in the 60-600 s range), while the third class features slow gravity mode vibrations of period typically 1h. All three classes provide a strong potential for sounding the internal properties of stars in these evolved phases of stellar evolution through asteroseismology. This has so far been exploited mainly for the rapid p-mode sdB pulsators, but the long period g-mode sdB pulsators, with the advent of space observations, carry good promises for sounding even deeper regions inside these stars. In this review paper, we summarize the properties of pulsating hot subdwarf stars and we outline progress that have recently occured in the asteroseismic exploitation of the pulsations observed in sdB stars.

[more ▼] The MULTISITE model [1] is based on polycrystalline plasticity and the underlying hypotheses of the model are (i) that the deformation of each grain is significantly influenced by the interaction with a limited number of adjacent grains, and (ii) that local strains deviate from their macroscopic average according to specific “relaxation modes”. The LAMEL model [2] is reformulated into the more general elastic-viscoplastic MULTISITE model permitting various relaxation modes. This model has been validated for cubic materials but hexagonal close-packed (HCP) crystals usually demonstrate larger anisotropy than cubic crystals. The model was used to simulate uniaxial tensile tests performed on rolled sheets made of Ti-6Al-4V. The Lankford coefficients (r) calculated in various directions in the plane of the sheet were analysed. In this study, different grain interaction hypotheses were tested. Besides, it appeared that the value of the critical resolved shear stresses (CRSS) of the different slip system families of the HCP metal had significant effects on the results. Their influence as well as the influence of the strain rate sensitivity parameter was examined.

[more ▼] Summary: Objectives. The aim of this study was to evaluate the objective voice results ofWendler’s glottoplasty in male-to-female transsexuals. Method. We retrospectively reviewed our patients treated with Wendler’s technique with minor modifications. Glottoplasty consisted in CO2-laser epithelial ablation of the anterior commissure and the two vocal folds in anterior third, suturing of the two vocal folds with two stitches of 3.0 resorbable thread, and application of fibrin sealant to strengthen the suture. Voice assessment was based mainly on fundamental frequency (F0), frequency range, jitter, maximum phonation time, phonation quotient, estimated subglottic pressure (ESGP) grade of dysphonia (G), and voice handicap index (VHI). These measures were taken before surgery and on the last follow-up visit. Results. Our series included 15 patients with a mean age of 36 years. The mean follow-up period was 7.2 months.We did not observe any early complications related to the technique. The comparison between the preoperative and the postoperative measurements, using Wilcoxon signed rank test, showed a significant improvement of median F0 from 139 to 191 Hz (P ¼ 0.006) with an increase in the grade of dysphonia (Gpre ¼ 0.2, Gpost ¼ 1, P ¼ 0.013) and ESGP (ESGPpre ¼ 8.1 ± 3.2, ESGPpost ¼ 12.0 ± 3.8, P ¼ 0.002). Other measurements, including VHI, did not show any significant differences pre- and postoperatively. Conclusion. Wendler’s glottoplasty can contribute to feminize the voice.

Rodríguez, S.M., Trono, K., Jones, L.R., Golemba, M., Campos, R. Instituto De Virología - Cicvya - Inta Castelar We sequenced the env gene from 28 BLV field strains from Argentina, and combined these sequences with 45 env sequences representing all the genetic groupings identified previously. These data were analyzed by phylogenetic analysis and similarity comparisons. Phylogenetic analyses showed the existence of five groups of sequences or genotypes. Four genotypes were supported by high bootstraps (89–100) and posterior probabilities (p=1.0), and the fifth one was supported by a high posterior probability (p=1.0) and moderate bootstrap (80–96) values. All these genotypes have one or more counterparts among the groupings identified previously, and thus many groups that were originally named differently correspond actually to the same genotype. Two sequences did not cluster with any other sequence, and were highly divergent when compared to the five groups mentioned above. This indicates that two extra genotypes could exist. The similarity comparisons were highly congruent with the phylogenetic analyses. The mean number of pair wise nucleotide substitutions between sequences from the same genotype was 11.1 (min. 6.5; max. 19), whereas it was 39.6 (min.36.8; max. 47.9) between sequences from different genotypes. Likewise, the mean number of amino acid substitutions in pair wise comparisons at the intra-genotype level was 3.3 (min. 0.4; max. 6.2), whereas it was 9.6 (min. 8.3; max. 13.5) at the inter-genotype level. Our analyses confirmed the existence of geographic clusters (p=6.838E-15, Chi2 test; p=4.583E-12, Fisher’s exact test).

LW is Research Director of the FNRS. We previously proposed to interfere with proviral loads in HAM/TSP patients by modulating lysine deacetylase activity using valproic acid (VPA). The strategy aims at activating viral gene expression in order to expose virus-positive cells to the host immune response. We conducted a single-center, two-year open-label trial, with 19 HAM/TSP volunteers treated with oral doses of VPA (20mg/Kg/day). Objectives were to assess biological response and clinical safety to VPA treatment in HAM/TSP patients. By microarray analysis, we show that VPA treatment moderately stimulated expression of cyclinD2 and Rho GTPase activating protein 18 in CD4-T cells. CD8-mediated lysis efficiency of Tax-expressing cells was unaltered by VPA treatment. The CD4-T cell turnover rate was calculated by GC/MS analysis from quantitative incorporation of deuterium into DNA. Transient increase in proviral loads correlated with accelerated proliferation. After 2 years, the proviral loads reached levels similar to those before treatment. The main clinical side effects were drowsiness (52%), tremor (47%), digestive symptoms (37%), vertigo (26%), and alopecia (10%). The frequency of side symptoms tended to decrease over the trial course. The neurological status over the study constituted the primary clinical safety measures. Disability Status Scale, muscle testing score, Ashworth score, and urinary dysfunction score showed no significant changes. Walking Time Test (WTT) slightly varied over the study except in 3 patients in whom the WTT variation rates were>20%. These 3 patients experienced drowsiness and tremor and improved rapidly after treatment discontinuation. Together, these observations indicated that long term treatment with VPA is safe but does not alleviate the condition of HAM/TSP.

[more ▼] Low-level line profile variability in the optical domain is a ubiquitous feature of O, Of and Wolf-Rayet type stars. This variability can arise from pulsations, from magnetic fields or wind structures (both small and large scales). For main-sequence O-type stars, the spectra display many absorption lines that provide stringent diagnostics of photospheric features. However, as the stars evolve off the main-sequence towards the Of and Wolf-Rayet stage, the stellar wind densities (and hence the wind optical depths) increase dramatically. The wind eventually dominates the formation of the entire spectrum rendering the investigation of photospheric structures more ambiguous. We discuss the observational analyses of the spectroscopic and photometric variability of massive stars of spectral type O, Of and WR. In particular, we highlight the search for a connection between the photospheric and the wind variability.

[more ▼] Chemical turbulent mixing induced by rotation can affect the internal distribution of μ near the energy-generating core of main-sequence stars, having an effect on the evolutionary tracks similar to that of overshooting. However, this mixing also leads to a smoother chemical composition profile near the edge of the convective core, which is reflected in the behavior of the buoyancy frequency and, therefore, in the frequencies of gravity modes. We show that for rotational velocities typical of main-sequence B-type pulsating stars, the signature of a rotationally induced mixing significantly perturbs the spectrum of gravity modes and mixed modes, and can be distinguished from that of overshooting. The cases of high-order gravity modes in Slowly Pulsating B stars and of low-order g modes and mixed modes in β Cephei stars are discussed.

[more ▼] HD 152219 is a massive binary system with O9.5 III and B1-2 III/V components and a short orbital period of 4.2 d. In a previous work, we showed that the primary star (M_{prim}˜21 M_&sun;) was presenting clear line profile variabilities (LPVs) that might be caused by nonradial pulsations (NRPs). In the present work, we report on an intensive spectroscopic monitoring, that aimed at unveiling the nature of the detected LPVs. Based on this new data set, we discard the NRPs and point out the Rossiter-McLaughlin effect as % being the cause of the observed LPVs. The upper limit derived on the amplitude of undetected NRPs, if any, is set at a couple of part per thousands of the continuum level.
