The small-scale fishing fleet of Corsica (France, NW Mediterranean) is mostly composed of small artisanal boats. The common spiny lobster, Palinurus elephas, is the most valuable of all caught species. As a result, it is the main target of most fishermen during the 7-months fishing season. Populations of this species seem to decrease since the 1950's. The aim of this study was to understand if this decline could be linked with overfishing, or if other biological, ecological or climatic factors could explain this population drop. To achieve this goal, we combined 1) a meta-analysis of all data concerning fishing effort and captures in published and grey literature and 2) an on-board monitoring program that started in 2004. Using obtained data, we followed fleet structure, fishing effort and captures evolution from 1950 to 2011. Our results point out an important capture decrease during the 20th century. This trend started during the 1950’s and 1960’s, when trammel nets replaced traditional wood traps. A micro-regional analysis revealed that exploitation intensity widely varied among different areas around the island. Moreover, landings and catch rates showed important spatial and temporal variations. This could be caused by changes in recruitment rates. However, recruitment processes of this species are still poorly understood. Improving our knowledge of common spiny lobster life cycle will likely lead to a more comprehensive and efficient assessment of Corsican stocks of this species. [less ▲]

The e-nose technology has enormous potentialities for in site monitoring of off-odours. However a number of limitations are associated with the properties of chemical sensors, the signal processing performances and the real operating conditions of the environmental field. The field experience of the research group included testing of a large amount of sensors in different sensor technologies and among those the metal oxide-based gas sensors (Figaro type) are the best gas sensors for long term application, as stated during more than 1 year of field testing. To be usable for the off-odours field measurement, the e-nose has to deal with the lack of long term stability of these sensors. The drift and the sensors replacement have to be considered. In order to appraise the time evolution of the sensors and the effect on the results of an electronic nose, experimentation has been performed during more than 3 years on two identical sensor arrays. The two arrays contain the same six Figaro sensors and are in the same sensor chamber of the e-nose system. Both arrays have worked continuously, without break. This paper presents the drift of some TGS sensors for 7 years as well as the difference in the temporal behaviour of identical sensors and the consequence on the e-nose results after the sensor replacement in the sensors array. A correction of the drift and of the replacement effect is applied and the classification results are exposed, with and without correction. [less ▲]

To our knowledge, the stability results reported in the literature only concern cells made from classical doctor-bladed or screen-printed nanoparticles films. This study focuses on the comparison of the long-term stability of these cells with DSSCs working with templated mesoporous films. Indeed, the increased surface area of templated films could lead to a faster degradation of the resulting cells. In accordance with IEC:1646:1996 standard tests, light soaking test at 45°C has been applied to determine the cells stability under prolonged illumination. Moreover, thermal stress in the dark has been applied. Unfortunately, due to the sealing material heat resistance, thermal stress test was only performed at 45°C. [less ▲]

The goal of this study is the evaluation of the long-term efficiency of voice therapy (> to 6 months) in the treatment of dysfunctional dysphonia . Four subjective measurements were performed on 29 patients: -A visual analogical scale (VAS) ranging from 0 (not efficient at all) to 100 (very efficient). -A question “Is the speech therapy still efficient?” Yes or no. -The G(rade), R(oughness) and B(reathiness) parameters from the GRBAS perceptual scale (evaluated by the patient measured on VAS). -The Voice Handicap Index-10 (VHI-10). The results show that 76% of the patients consider that the voice therapy is still efficient. In regard to G.R.B., we observe a high score for G (median: 77). The score for R is lower (median R: 12). G and R are significantly correlated (r Spearman=0.516, p=0.004), but the satisfaction of the vocal quality does not seem correlated to B (p=0,251, NS). The median values of VHI 10 shows a significant improvement from 15 to 10 (p=0,017). In addition, the correlations between the judgment on the treatment efficiency and vocal quality (r=0,623, p<0,001) and between VHI-10 and the length of treatment (r=0.416, p=0,035) are significant. The first correlation shows that the most satisfied patients when it comes to the vocal therapy are also the most satisfied when it comes to their vocal quality. The second correlation specifies that the longer the treatment, the higher the grade of vocal handicap. Voice therapy is efficient in the long term and is worth to be prolonged for difficult cases [less ▲]

The global neutrino physics community is developing a multi-decade physics program to measure unknown parameters of the Standard Model of particle physics and search for new phenomena. The program will be carried out as an international, leading-edge, dual-site experiment for neutrino science and proton decay studies, which is known as the Deep Underground Neutrino Experiment (DUNE). The detectors for this experiment will be designed, built, commissioned and operated by the international DUNE Collaboration. The facility required to support this experiment, the Long-Baseline Neutrino Facility (LBNF), is hosted by Fermilab and its design and construction is organized as a DOE/Fermilab project incorporating international partners. Together LBNF and DUNE will comprise the world’s highest-intensity neutrino beam at Fermilab, in Batavia, IL, a high-precision near detector on the Fermilab site, a massive liquid argon time-projection chamber (LArTPC) far detector installed deep underground at the Sanford Underground Research Facility (SURF) 1300 km away in Lead, SD, and all of the conventional and technical facilities necessary to support the beamline and detector systems.

Background: Diagnosis of childhood active tuberculosis (aTB) or latent Mycobacterium tuberculosis (Mtb) infection (LTBI) remains a challenge, and replacement of tuberculin skin tests (TST) by commercialized interferon-gamma release assays (IGRA) is not currently recommended. Methods: 266 children between 1 month and 15 years of age, 214 being at risk of recent Mtb infection and 51 being included as controls, were prospectively enrolled. According results of clinical evaluation, TST, chest X-Ray and microbiology, children were classified as non-infected, LTBI or aTB. Long-incubation time PPD-, ESAT-6-, and CFP-10-IGRA were performed and evaluated for their accuracy to correctly classify the children. Results: Whereas both TST and PPD-IGRA were suboptimal to detect aTB, combining CFP-10-IGRA with TST or with PPD-IGRA allowed us to detect all the children with aTB, with 96% specificity for children who were positive for CFP-10-IGRA. Moreover, combination of CFP-10- and PPD-IGRA also detected 96% of children classified as LTBI, but a strong IFN-γ response to CFP-10 (>500 pg/ml) was highly suggestive of aTB at least among children less than 3 years old. Conclusions: Long-incubation time CFP-10- and PPD-IGRA should help the clinicians to identify quickly aTB or LTBI in young children. [less ▲]

Students were exposed to a priming task in which subliminal representations of the goal of studying were directly paired (priming-positive group) or not (priming group) to positive words. A control group without subliminal prime of the goal was added. Just after the priming task, students performed an easy or a difficult learning task based on their coursework. Participants in the priming-positive group performed better and had a stronger decrease of pulse transit time and pulse wave amplitude reactivity than participants of the two other groups, but only during the difficult condition. Results suggested that subliminal priming induces effortful behavior extending over twenty five minutes but only when the primes had been associated with visible positive words acting as a reward. These findings provide evidence that subliminal priming can have long-lasting effects on behaviors typical of daily life. [less ▲]

BACKGROUND: Unwanted male-pattern pilosity is a heavy psychological burden and can cause distress for male-to-female transsexuals. Orchidectomy and oestrogen supplementation combined with antiandrogens fail to make hair disappear. AIMS: To study the effect of long-pulsed ruby laser treatment. RESULTS: Hair density was successfully abated on the beard and chest of three male-to-female transsexuals. A lingering effect over 6 months with a 50-90% hair density reduction was obtained. CONCLUSION: Photothermolysis using the long-pulsed ruby laser is a promising, well-tolerated method of hair removal in male-to-female transsexuals under oestrogen supplementation and antiandrogens.
