Topical application of insecticidal compounds allows directly exposing these substances on insect tissues and measuring their toxicity while ignoring many factors. However, this technique remains difficult to apply on mosquito larvae considering their aquatic lifestyle. Micro-injection could be used for the direct deposition of toxic compounds in the larvae. Capillaries exhibiting an injection tip with an external diameter of 0.5 mm have been designed from silica tubes. For each treatment, a capillary is mounted on a pump connected to a flow rate regulator. Culex quinquefasciatus larvae were injected with 10^7 spores/ml of entomopathogenic fungi (Aspergillus clavatus, Metarhizium anisopliae, Metarhizium sp.). Mortalities were recorded daily during 72h. The distribution of spores stained with methylene blue and injected into the body of larvae was also observed according to the system described. Results showed that spores were distributed over the whole body. The injection of Aspergillus clavatus, Metarhizium anisopliae and Metarhizium sp spores induced corrected mortalities of 62%, 53% and 57% after 72h, and differed statistically from control groups. Finally, post-mortem emergences of filaments from dead larvae were observed in the case of the three fungal strains confirming spore viability. Injection of inactivated spores (or inert bodies of similar size) could help to reject the hypothesis of a response due to the presence of foreign bodies. [less ▲]

We briefly introduce hot subdwarfs and their evolutionary status before discussing the different types of known pulsators in more detail. Currently, at least six apparently distinct types of variable are known among hot subdwarfs, encompassing p- as well as g-mode pulsators and objects in the Galactic field as well as in globular clusters. Most of the oscillations detected can be explained in terms of an iron opacity mechanism, and quantitative asteroseismology has been very successful for some of the pulsators. In addition to helping constrain possible evolutionary scenarios, studies focussing on stellar pulsations have also been used to infer planets and characterize the rotation of the host star.

Hot B subdwarfs (sdB) are hot and compact helium core burning stars of nearly half a solar mass that can develop pulsational instabilities driving acoustic and/or gravity modes. These evolved stars are expected to be chemically stratified with an almost pure hydrogen envelope surrounding a helium mantle on top of a carbon/oxygen enriched core. However, the sdB stars pulsating in g-modes show regularities in their observed period distributions that, surprisingly (at first sight), are typical of the behavior of high order g-modes in chemically homogeneous (i.e., non-stratified) stars. This led to a claim that hot B subdwarfs could be much less chemically stratified than previously thought. Here, we reinvestigate trapping effects affecting g-modes in sdB stars. We show that standard stratified models of such stars can also produce nearly constant period spacings in the low frequency range similar to those found in g-mode spectra of sdB stars monitored with Kepler.

Lactate production is associated with total spermatozoa concentration. It negatively affects preservation of total and progressive motility, showing an effect of by-products of anaerobic metabolism on long-term storage. Moreover, our data show that non-progressive motile spermatozoa are highly associated to lactate concentration, and thus, anaerobic glycolysis. More studies are required to determine relative contributions of aerobiosis and anaerobiosis to spermatozoa motility under different storage conditions. [less ▲]

This research aims to formalize the spatiotemporal relationships of membership between individuals and the groups to which they belong. Specifically, we analyze how the membership to a community evolves over time considering past, present and future connections. The framework developed for this research is presented using an ontological approach. We demonstrate a specific domain ontology application for spatiotemporal membership using BFO2, an updated version of the Basic Formal Ontology. Key to this work is the representation of membership, modeled through different kinds of mereological relations possible with a group, for example, pre-member, active member, and alumni that capture how membership evolves and changes over time. The semantic web rule language (SWRL) is used to express the different spatiotemporal events that relate to membership and their consequences on membership such as subscription, graduation and reunion events. Mobility events are also included in the model. SWRL supports reasoning using the ontology and studying the evolution of membership between people and their various groups. We use the environment of a university community as an exemplar to develop and test the formalizations. However, the ideas are generalizable to a wide range of spatiotemporal domains, for example, these ideas hold for citizenship modeling or for consumers shopping at certain retail chains. The study of the evolution of membership connections between these entities and groups lends important insights for many different kinds of event planning. [less ▲]

We present a study of of copper-doped Al2O3 films prepared by sol-gel deposition. The films were spin-coated on Si and quartz substrates and a high-temperature treatment was conducted in the range 500-800 °C in oxygen or nitrogen. The impact was followed of the annealing procedures on the AlxCu1-xO3 films's properties. XRD was used to determine the films' structure; it revealed a mixture of amorphous and crystalline phases. Optical characterization was performed by UV-VIS spectroscopy. The sol-gel films prepared are very transparent. The band gaps of the Al-Cu-O films were estimated from the optical data, with the values ranging from 3.4 to 4.8 eV depending on the Cu content, the annealing and the gas ambients. [less ▲]

A six and a half year (January 2005 to May 2011) comparison of CO2 concentration observations has been performed at Jungfraujoch, Switzerland and the city of Bern using two different measurement techniques run by the University of Bern (UBE) and the University of Liege (UL). The UBE systems at Jungfraujoch and Bern are both combined systems for atmospheric oxygen and CO2 measurements. The cryogenically dried air is analysed for CO2 with a Maihak analyser based on the broad-band infrared absorption technique. The measurement frequency is every second but the final reported data are averages of six minute periods. UL is measuring the solar infrared spectrum since 1950 at Jungfraujoch. On its way through the atmosphere, the solar spectrum is modulated depending on the abundant gas species and their amount in the column. Since some gases like CO2 absorb the solar infrared radiation at particular wavelengths and the extinction is proportional to the gas concentration, it is possible to determine the gas concentration in the column above the sensor. At the conference, we will present the three observational records for the six and a half year period. The results show for all three records a distinct, but different seasonality. The seasonalities of the UL and UBE record at Jungfraujoch are lower than the seasonality in the city of Bern, i.e. 4.5 ppm per year and 9 ppm per year for the column and the in- situ record respectively, whereas the seasonality in the city of Bern is 31 ppm per year. Also the maxima and minima of the Jungfraujoch measurements are delayed by several weeks compared to the measurements in the city of Bern. The annual increase of the CO2 concentration of the UBE and UL records of Jungfraujoch are in good agreement with 1.94 ppm per year and 1.90 ppm per year, respectively. The annual increase of the CO2 concentration at the urban site is a bit higher at 2.01 ppm per year. [less ▲]

This work addresses the computation of the set of reachable configurations of linear hybrid automata. The approach relies on symbolic state-space exploration, using acceleration in order to speed up the computation and to make it terminate for a broad class of systems. Our contribution is an original method for accelerating the control cycles of linear hybrid automata, i.e., to compute their unbounded repeated effect. The idea consists in analyzing the data transformations that label these cycles, by reasoning about the geometrical features of the corresponding system of linear constraints. This approach is complete over Multiple Counters Systems (MCS), and is able to accelerate hybrid transformations that are out of scope of existing techniques. [less ▲]

Objectifs En Belgique, les mesures de prévention médicalisées restent inéquitablement distribuées dans plusieurs domaines (vaccins, dépistages, conseil cardio-vasculaire, etc.). Une recherche antérieure au moyen d’une échelle d’attitude a mis en évidence trois facteurs pouvant modeler l’attitude des médecins généralistes (MG) envers la prévention : 1. Evaluation de pratique. 2. Sentiment de responsabilité envers la santé des patients. 3. Compétences professionnelles particulières (CPP) : références scientifiques, positionnement dans le système de soins, délégation de tâches à des paramédicaux. Cette étude a cherché à établir des profils de MG par rapport à la prévention, en croisant les scores sur ces trois facteurs et les variables sociodémographiques. Méthode Les réponses des 457 MG répondants à l’échelle d’attitude ont été soumis à des analyses multivariées, en prenant comme variables dépendantes les scores obtenus sur les trois facteurs, et comme variables indépendantes l’ancienneté, le sexe, la langue, le lieu de pratique, le travail dans un centre de prévention (ONE, planning, PSE), le type de pratique (solo ou divers types d’association). Résultats Le type de pratique est le seul déterminant qui influence les 3 facteurs, avec un gradient des pratiques solo vers les maisons médicales, en passant par les associations mono- puis pluridisciplinaires. Les MG ayant moins de 20 ans de pratique ont de meilleurs scores en évaluation et CPP. Les hommes ont de meilleurs scores en évaluation, et les pratiques urbaines se distinguent en CPP. La langue influence tantôt dans un sens tantôt dans l’autre. Il n’y a pas d’influence du fait de travailler dans un centre de prévention. Conclusion Une diffusion plus large et équitable des actes préventifs passe par la prise en compte de facteurs personnels et organisationnels propres aux MG. Les associations pluridisciplinaires semblent mieux préparées pour atteindre cet objectif. [less ▲]

Plant productivity is partly dependent on soil fertility, which is why it is important to know the distribution of the chemical and morphological properties of the soil. The study was conducted at an experimental site located on a steep forested slope planted with conifers. Consequently, prior to the study of variations in soil and vegetation characteristics over time, we analysed the chemical and morphological properties along the slope. Eight pits were dug and sampled by horizon. Root density, bulk density and stone content measurements were performed as well as the analysis of the soil chemical properties (pH, K, Mg, Na, Ca and P content). The results confirm the significance of vertical differentiation as one moves along the profile. [less ▲]

Validation of the erosion models requires field data. To date, many authors continue to highlight the paucity of accurate field observations and long-term enough studies. The fields observations are often put aside because these measures are difficult to obtain: weighty experimental devices, climatic dependence, . . . Hence the models are evolving and propose refined calculation procedures including for instance the calculation of landscape evolution. The need of field data therefore increases and new measuring strategies should arise. In the centre of Belgium we choose an agricultural watershed quite representative of the local context. It covers 124 ha of loamy soil with more than 90% of arable land and a weak proportion of forest and artificial lands. The slope ranges between 0 and 9%. Instrumentation on the watershed includes meteorological observations and discharge measurement coupled with water sampling at different outlets. The weather data (radiation, temperature, wind velocity, relative humidity and rainfall) and discharge measurement (comparison between Doppler and pressure sensors) will allow us to model the hydrological behaviour of the catchment. Rainfall readings (tipping buckets) are completed with erosivity readings (disdrometer). Erosivity, together with soil data, land use and agricultural practices observations on field, will be used as entry in the Landsoil model. The sediment samplings at 3 points in the catchment will give an insight of the sediment delivery of 3 subcatchments. The Landsoil model calculates the evolution of the DTM through time. This cannot be compared to measurements at the outlet and requires further data collection. Older elevation data and/or archaeological data are a possible source of information even if their precision remains scarce in our context. 1950’s soil surveys are on the contrary really informative since they detail the horizons depth in a spatial way and can be compared to new observation across the watershed. Coupled with unmanned aerial system, they should allow us to test the model performances and improve our knowledge of the spatial patterns of erosion and deposition. [less ▲]

Ce travail vise à interroger la manière dont les jeux vidéo et les dynamiques de détournement qu’ils suscitent chez les joueurs redéfinissent la traditionnelle opposition entre consommation et création. Dans ce but, nous étudierons un usage spécifique du médium vidéoludique qui s’est institué en véritable pratique créative sur internet : le speedrun (et son dérivé, le tool-assisted speedrun). L’analyse se déroulera en deux temps : une première partie envisagera les déplacements concrets qu’opère le speedrun dans les notions liées au pôle de la réception (qu’est-ce qu’être un joueur ou un spectateur au sein de ce domaine ?) ; la seconde étudiera la façon dont cette pratique participe à redéfinir le pôle de la production (que deviennent les notions d’auteur, d’œuvre et de création dans le cadre de cette activité ?).

We present several examples of partial mode identification for rapidly pulsating subdwarf B stars on the basis of multi-colour observations. Three targets (V391 Per, Balloon 090100001, and EC 11583−2708) were analysed from multi-colour photometry, while studies were conducted from time-series spectrophotometry for two further stars (EC 20338−1925 and EC 01541−1409). In all cases, periodicities strongly dominating the frequency spectrum are associated with radial modes, indicating a clear hierarchy according to visibility when integrating over the visible disk of the star.

Depuis une décennie, les découvertes de matériaux colorants se multiplient parmi les sites dont les occupations remontent au Paléolithique moyen et au Paléolithique supérieur ancien. L’intérêt qu’elles suscitent tient à ce qu’elles sont susceptibles de révéler des pratiques techniques diverses et complexes, mais il tient aussi à leur forte potentialité à traduire des pratiques symboliques du fait de leur pouvoir colorant intense et des couleurs exploitées : le rouge et le noir. C’est sur le gisement châtelperronien de la grotte du Renne à Arcy-sur-Cure (Yonne), fouillé de 1949 à 1963 par André Leroi-Gourhan, qu'environ 2000 matières colorantes découvertes ont conduit à échafauder des théories concernant leurs transformations et leurs utilisations qui méritaient d’être éprouvées. Il est supposé, depuis leur découverte, qu’elles ont fait l’objet d’un chauffage contrôlé qui visait à en modifier la couleur, le chauffage permettant de transformer les matières colorantes jaunes (hydroxydes de fer) en orangé, en rouge et en violacé (oxydes de fer). De cette hypothèse découle la théorie selon laquelle les Néandertaliens ont exploité les matières colorantes en tant que pigment pour des réalisations symboliques, voire d’ordre esthétique, ce qui n’a pas encore pu être prouvé. La présente étude, fondée sur le croisement des données issues des analyses de la nature physico-chimique et pétrographique des assemblages de matières colorantes, mais aussi sur leur intégration dans le gisement, en association avec des structures d’habitat dont la conservation est exceptionnelle, et sur une série d’expérimentations visant à caractériser les poudres obtenues par différents moyens a permis de définir les choix techniques qui ont présidé à l’approvisionnement en matières colorantes dans tous les niveaux d’occupation châtelperroniens de la grotte du Renne. Il a ainsi été possible de démontrer qu’aucune des matières colorantes, rouges ou noires, n’a fait l’objet d’un chauffage préalablement à son utilisation, bien au contraire de ce qui avait été supposé jusqu’ici. Ces matières colorantes ont fait l’objet d’un approvisionnement raisonné auprès de formations géologiques affleurant ponctuellement. L’exploitation de ces gîtes de matières premières colorantes a été la même durant toute la séquence châtelperronienne et s’est orientée préférentiellement vers des matériaux que l’on peut aisément réduire en poudre. L’assemblage des matières colorantes de la grotte du Renne révèle à la fois une permanence des pratiques techniques et culturelles qui ont trait à l’emploi de matières colorantes et un profond ancrage des connaissances et de la compréhension des multiples propriétés et qualités de ces matériaux intensément mises à profit dans des activités diverses, domestiques, artisanales et manifestement aussi d’ordre symbolique, de telle sorte que le gisement châtelperronien était tout de rouge et noir.

the field data come from plot scale studies, the watershed scale seems to be more appropriate to understand them. Currently, small unmanned aircraft systems and images treatments are improving. In this way, 3D models are built from multiple covering shots. When techniques for large areas would be to expensive for a watershed level study or techniques for small areas would be too time consumer, the unmanned aerial system seems to be a promising solution to quantify the erosion and deposition patterns. The increasing technical improvements in this growth field allow us to obtain a really good quality of data and a very high spatial resolution with a high Z accuracy. In the center of Belgium, we equipped an agricultural watershed of 124 ha. For three years (2011-2013), we have been monitoring weather (including rainfall erosivity using a spectropluviograph), discharge at three different locations, sediment in runoff water, and watershed microtopography through unmanned airborne imagery (Gatewing X100). We also collected all available historical data to try to capture the “long-term” changes in watershed morphology during the last decades: old topography maps, soil historical descriptions, etc. An erosion model (LANDSOIL) is also used to assess the evolution of the relief. Short-term evolution of the surface are now observed through flights done at 200m height. The pictures are taken with a side overlap equal to 80%. To precisely georeference the DEM produced, ground control points are placed on the study site and surveyed using a Leica GPS1200 (accuracy of 1cm for x and y coordinates and 1.5cm for the z coordinate). Flights are done each year in December to have an as bare as possible ground surface. Specific treatments are developed to counteract vegetation effect because it is know as key sources of error in the DEM produced by small unmanned aircraft systems. The poster will present the older and more recent changes of relief in this intensely exploited watershed and notably show how unmanned airborne imagery might be of help in DEM dynamic modelling to support soil conservation research.

We present the preliminary seismic modeling of one of the hottest and most compact subdwarf pulsators, PB 8783 (EO Ceti). This is a well observed hot subdwarf star, including a 78 d campaign in white light photometry that we carried out at Mount Bigelow, Arizona, during the fall 2007. PB 8783 has also been observed at length in spectroscopy, revealing a spectrum highly contaminated by a main sequence companion. It is extremely difficult to disentangle the contribution of the two components and, as a consequence of this, the exact nature of the hot subdwarf (sdB or sdO star) is undetermined. We propose here to test the two hypotheses by asteroseismology. Although the sdB possibility cannot be excluded, the pulsation modes observed in PB 8783 are much better accommodated in the case of an sdO star. [less ▲]

The seasonal storage should allow reaching a nearly 100 % solar fraction for space heating of a "low energy" building". The selected adsorbent and adsorbate are respectively bromide strontium and water. The studied system, including the building and the ground exchanger, is simulated using the dynamic simulation software TRNSYS. Results show that expected performances are reached with a borehole of 100 m. The evaporation temperatures computed are really close to 0°C which might cause some problems. But an advanced research would maybe impose a deeper borehole to avoid cooling the ground on the long term. [less ▲]

The Extreme Ultraviolet Imager (EUI) on-board the Solar Orbiter mission will provide image sequences of the solar atmosphere at selected spectral emission lines in the extreme and vacuum ultraviolet. For the two Extreme Ultraviolet (EUV) channels of the EUI instrument, low noise and radiation tolerant detectors with low power consumption and high sensitivity in the 10-40 nm wavelength range are required to achieve the science objectives. In that frame, a dual-gain 10 µm pixel pitch back-thinned 1k x 1k Active Pixel Sensor (APS) CMOS prototype has been tested during the preliminary development phase of the instrument, to validate the pixel design, the expected EUV sensitivity and noise level, and the capability to withstand the mission radiation environment. Taking heritage of this prototype, the detector architecture has been improved and scaled up to the required 3k x 3k array. The dynamic range is increased, the readout architecture enhanced, the power consumption reduced, and the pixel design adapted to the required stitching. The detector packaging has also been customized to fit within the constraints imposed by the camera mechanical, thermal and electrical boundaries. The manufacturing process has also been adapted and back-thinning process improved. Once manufactured and packaged, a batch of sensors will undergo a characterization and calibration campaign to select the best candidates for integration into the instrument qualification and flight cameras. The flight devices, within their cameras, will then be embarked on the EUI instrument, and be the first scientific APS-CMOS detectors for EUV observation of the Sun. [less ▲]

Les nouvelles "Holunderblüte" (1863) de Wilhelm Raabe et "Ein Bekenntnis" (1887) de Theodor Storm allient psychologie, maladie et narration. Les deux textes racontent l’histoire de médecins qui à la fin de leur vie se questionnent sur leur propre responsabité dans un épisode du passé qui changea définitivement le cours de leur existence: la maladie et la mort de l’être qui leur était le plus cher (une jeune fille chez Raabe, l’épouse chez Storm). Par rapport aux études psychanalytiques très nombreuses dans la recherche sur Storm, cette étude souhaite montrer que la profondeur psychologique des textes doit être décrite par une analyse tenant compte du rôle anthropologique de la narration. Au niveau des narrateurs, la narration a ainsi une valeur curative pour ces deux médecins souffrant de sentiments de culpabilité et souhaitant retracer leur vie comme un sentier linéaire, cohérent et imbibé de sens. Les fonctions anthropologiques de la narration (production de sens, réduction de la contingence et de l’angoisse) auxquelles font appel ces individus sont toutefois relativisées par les textes eux-mêmes qui par leur forme et par le motif du labyrinthe évoquent l’aléatoire, la contingence et l’absence de sens.

Cataract is the opacity of the lens, causing impairment of vision or even blindness. Today, a surgery is still the only available treatment. The intraocular lens (IOL) is a polymer implant designed to replace the natural lens in the cataract surgery. However, the bioinert materials could not satisfy the unmet need in the secondary cataract control. Posterior capsular opacification (PCO, or Secondary Cataract), characterized by a thick and cloudy layer of lens epithelial cells (LECs), is the most common postoperative complication. In our research, a bioactive molecule is immobilized onto the conventional acrylic hydrophilic polymer pHEMA (Poly(2-hydroxyethyl methacrylate)) using oxygen plasma treatment followed by deposition. The RGD peptide sequence, being well-known for its ability to promote cellular attachment by binding to integrin receptors, is designed to stimulate the adhesion of LECs on the IOL. Our data show the peptide immobilized biomaterial not only exhibits similar optical property, but also reveals enhanced biological properties in cell adhesion and cell morphology maintenance. By means of surface functionalization of IOL to stimulate LECs adhesion, the secondary cataract could be controlled. [less ▲]

The work presents a sol-gel approach with two types of solvents for ZnO films deposition in view of varying the films' structural and optical properties. The ZnO films were characterized by X-Ray diffraction (XRD) and found to have a polycrystalline wurtzite phase structure. The grain sizes and the lattice parameters were determined; it was established that the ZnO crystallites' size increases with the annealing temperatures from 25 nm to 36 nm. The ZnO films possess high transmittance in the visible spectral range. Further, the optical band gap values were estimated. The material's vibration properties were analyzed by Fourier Transform Infrared (FTIR) spectroscopy. The two technological sol-gel approaches for deposition of ZnO films, using two different solvents, proved to be successful in producing structures with different structural and optical properties. The thin films fabricated were very smooth and uniform and exhibited a high transparency in the visible spectral range. [less ▲]

Understanding the formation of sdB stars is one of the remaining challenges of stellar evolution theory. Competing scenarios have been proposed to account for the existence of such evolved objects. They give quite different mass distributions for resulting sdB stars. Detailed asteroseismic analyses, including mass estimates, of 15 pulsating hot B subdwarfs have been published in the past decade. Masses have also been reliably determined by light curve modeling and spectroscopy for 7 sdB components of eclipsing or reflection binaries. We present here the empirical mass distribution of sdB stars on the basis of these samples. Implications are also briefly discussed. [less ▲]

The toxicity of Fyto11, a plant resistance elicitor commercial formulation used to increase the natural resistance of Cucurbitaceae (cucumber, zucchini and melon) and Solanaceae (tomato and sweet pepper) against powdery mildew under greenhouse conditions, has been assessed on several beneficial arthropods: the honeybee Apis mellifera, the predatory miteTyphlodromus pyri, the aphid parasitic wasp Aphidius rhopalosiphi and the aphid predator Episyrphus balteatus. Tested at 0.5% and 1.0% spray dilution on plants, Fyto11 did not lead to significant corrected mortalities for E. balteatus larvae and adult wasps of A. rhopalosiphi, with a maximum of 5.4% mortality. No effects on reproduction capacity of the parasitic wasps were observed. The exposure of T. pyri protonymphs to Fyto11 on glass plates lead to corrected mortalities of 1.1% and 32.6% at 0.5% and 1.0% and to a reduction of female fertility of 9.0% and 25.4%, compared to the control performance. When assessed on the honeybee by contact and oral exposure, Fyto11 did not lead to significant effects, with LD50 estimated as > 10 μg a.i./bee (oral) and 12.5 μg a.i./bee (contact), leading to HQ ratio < 50 and classifying the product at no or low risk for honeybees. These results showed that the product was harmless for all beneficials at the proposed commercial rate, except for T. pyri at 1.0% on glass plates, where the product was rated as slightly harmful. Even if all the beneficial species’ diversity has not been assessed with this product, negative effects on non-target organisms are not expected in field conditions and Fyto11 can be considered as compatible with IPM programs.

Monolithic, large grain, (RE)Ba2Cu3O7 high-temperature superconductors (where RE denotes a rare-earth ion) are known to be able to trap fields in excess of several teslas and represent thus an extremely promising competing technology for permanent magnet in several applications, e.g. in motors and generators. In any rotating machine, however, the superconducting permanent magnet is subjected to variable (transient, or alternating) parasitic magnetic fields. These magnetic fields interact with the superconductor, which yields a reduction of the remnant magnetization. In the present work we quantify these effects by analysing selected experimental data on bulk melt-textured superconductors subjected to AC fields. Our results indicate that the non-uniformity of superconducting properties in rather large samples might lead to unusual features and need to be taken into account to analyse the experimental data. We also investigate the evolution of the DC remnant magnetization of the bulk sample when it is subjected to a large number of AC magnetic field cycles, and investigate the experimental errors that result from a misorientation of the sample or a mispositioning of the Hall probe. The time-dependence of the remnant magnetization over 100000 cycles of the AC field is shown to display distinct regimes which all differ strongly from the usual decay due to magnetic relaxation.

Long period B subdwarf (sdB) pulsators, when observed from space with the satellites CoRoT and Kepler, show particularly rich g-mode oscillation spectra with often hundreds of frequencies. In many of these pulsation spectra, regularities in the observed period distributions typical of high order g-modes in chemically homogeneous stars have been reported. This led to a claim that sdB stars could be much less chemically stratified than previously thought. In this paper, we show that such an interpretation is unfounded. We reinvestigate trapping effects on g-modes in sdB stars in view of current observations and show that ”standard” stratified models can also produce nearly quasi-constant period spacings in the low frequency range which are comparable to those observed in the g-mode spectra of these stars.

This study explores the role of seismic activity in explaining spatial and temporal variation in sediment export from the Siret basin in Romania. Based on long-term (>30 years) sediment export measurements for 38 subcatchments, we found that spatial variation in sediment yield (SY) is strongly correlated to the degree of seismic activity and catchment lithology. Combined, these factors explain 80% of the variation in SY. To investigate the role of earthquake-triggered landslides in explaining these correlations, we studied the temporal variability in sediment concentrations before and after the 7.4 Mw earthquake of 1977 for ten subcatchments. Despite the fact that this earthquake triggered many landslides, only one subcatchment showed a clear (3-fold) increase in sediment concentration per unit discharge after the earthquake. This shows that, although prolonged seismic activity strongly controls average SY, individual earthquakes do not necessarily affect sediment export at short timescales. Copyright © 2014 IAHS Press.

Asteroseismic modeling of subdwarf B (sdB) stars provides measurements of their fundamental parameters with a very good precision; in particular, the masses and radii deter- mined from asteroseismology are found to typically reach a precision of 1% containing various uncertainties associated with their inner structure and the underlying microphysics (composition and transition zones profiles, nuclear reaction rates, etc.). Therefore, the question of the accuracy of the stellar parameters derived by asteroseismology is legitimate. We present here the seismic modeling of the pulsating sdB star in the eclipsing binary PG 1336-018, for which the mass and the radius are independently and precisely known from the modeling of the reflection/irradiation effect and the eclipses observed in the light curve. This allows us to quantitatively evaluate the reliability of the seismic method and test the impact of uncertainties in our stellar models on the derived parameters. We conclude that the sdB star parameters inferred from asteroseismology are precise, accurate, and robust against model uncertainties. [less ▲]
