- The ANTARES Neutrino Telescope was completed in May 2008 and is the first operational Neutrino Telescope in the Mediterranean Sea. The main purpose of the detector is to perform neutrino astronomy and the apparatus also offers facilities for marine and Earth sciences. This paper describes the design, the construction and the installation of the telescope in the deep sea, offshore from Toulon in France. An illustration of the detector performance is given.

- The ANTARES neutrino telescope, to be immersed depth in the Mediterranean Sea, will consist of a three-dimensional matrix of 900 large area photomultiplier tubes housed in pressure-resistant glass spheres. The selection of the optimal photomultiplier was a critical step for the project and required an intensive phase of tests and developments carried out in close collaboration with the main manufacturers worldwide. This paper provides an overview of the tests performed by the collaboration and describes in detail the features of the photomultiplier tube chosen for ANTARES. (c) 2005 Elsevier B.V.

- Aims To explore whether music can reduce anxiety and pain in patients who underwent diagnostic endoscopic examinations in conscious and deep sedation and to assess degree of satisfaction and willingness to repeat the procedure. Design Prospective study led by nursing. Methods Between March 2019-June 2019, consecutive outpatients undergoing endoscopic examinations were simple matched into four groups: Group 1: conscious sedation with music; Group 2: conscious sedation without music; Group 3: deep sedation with music and Group 4: deep sedation without music. Ten minutes before the procedure, two trainee nurses applied music.State-Trait Anxiety Inventorywas used to evaluate anxiety. Results Before and at the end of the procedure, patients who listened to music had a lower level anxiety than those who did not listen and, also, reported lower pain intensity during procedure. Only within Group 1 median anxiety, measured after the procedure, is lower than that measured before. In the bivariate logistic regression model, pain and listening to music were independent factors for satisfaction and willingness to repeat procedure. Conclusion music in digestive endoscopy reduce pain and anxiety in conscious sedation, thus could be used to reduce anxiety in support to conscious sedation leading to lower usage of deep sedation and consequently reduction of costs and adverse events. Impact Anxiety in digestive endoscopy limits patients' satisfaction. Music in digestive endoscopy as a specific nursing intervention could reduce anxiety of patients. This nursing intervention study confirms positive effect of music in digestive endoscopy. As part of nursing management, the addition of music to daily care practice in digestive endoscopy may reduce anxiety and increase the patient's degree of satisfaction. Use of music could limit deep sedation use in digestive endoscopy with consequent reduction of risks for patients, execution times, and costs of procedures.

- The formation mechanisms of secondary ions from organic targets under MeV ion bombardment were studied with a high-resolution time-of-flight (TOF) mass spectrometer. Promptly formed ions Hn+, Cn+ and CnH+ were used for calibrating the TOF scale. Theoretical flight times of other ions were calculated according to the calibration curve and compared to experimentally determined values. The TOF values of non-specific low mass fragments formed via rearrangement or breaking of several bonds and/or abstraction of several atoms, agree well with the theoretical values. On the other hand, target-specific organic ions, including molecular ions of peptides, have longer TOF values than predicted by the calibration curve. Time delays of a few hundred picoseconds were found for low-mass specific fragments, and a few nanoseconds for peptide molecular ions. For protonated species and non-covalent clusters, the delays are larger than for pre-formed and radical molecular ions. Metals contained in organic samples, as contamination, also give delayed ions. For inorganic targets of LiBF4, significant delays were found for the clusters (LiF)nLi+ with n >3. A strong correlation was observed between the delay of an ion and the tailing of its kinetic energy distribution. The conclusion was made that the majority of target-specific ions are formed in the gas phase, at a distance from the target surface of the order of 1 μm.
