    Abstract Background Over the last few years, differential ion mobility spectroscopy (DMS) has become an important tool in medical research. There are attempts to find markers for specific diseases in exhaled air, using this technology as a non-invasive early diagnosis. Objective In the present research, exhaled air from 78 patients with known diagnosis and 39 control persons were tested with a DMS system from Sionex. Results Bronchial asthma showed a pattern of 6 characteristic points in a discriminant analysis. Patients with diagnosed hypertension showed a characteristic pattern with 4 points, hypothyroidism 2 points; increased LDL cholesterol 3 points, and type II diabetics treated with insulin 4 spots. No significant differences with respect to the control group were found in chronic obstructive pulmonary disease patients. The DMS pattern in the tested asthmatics showed a partial change depending on different medications used. Conclusion Differential ion mobility spectroscopy offers promise as a helpful diagnostic tool.</p

    International audienceResearch on fireballs and meteorites has always been of interest to the public, due to the beauty of shooting stars in the night sky and to the extraterrestrial origin of meteorites. A fireball observation network called FRIPON [1] (Colas et al, 2015) is currently being setup, funded by ANR (Agence Nationale pour la Recherche). It will cover France with 100 cameras and is expected to be operational for the end of 2015. FRIPON will detect fireballs and hence allow us to define meteorite strewn fields within 24h, so that meteorite searches can be launched very early on. Because of the need to search all over France, including in private land, it is important that the general public be aware of our project and be willing to help or participate. Indeed, as the main goal of FRIPON is to recover fresh meteorites (within a few days), our aim is to be able to organize a search with at least 50 persons to scan an area of a few km2 within a week. Help from the public would hence be most helpful but it is also important to have an operational and trained research team. This project thus appears as a unique occasion to involve the public in a scientific project while promoting informal scientific education. This prompted us to set up Vigie-Ciel, a citizen science network centered on meteorite recovery. FRIPON is an open network based on open-source software, it will accept citizenrun cameras. In addition to fireballs, it will allow scientists and Vigie-Ciel participants to study anything that can be observed by all-sky cameras: bird migrations, bats, clouds, lightning, etc. The data will be freely available to all

    Rrecovery and planned study of the Saint-Pierre-Le-Viger meteorite: an achievement of the FRIPON/Vigie-Ciel citizen science program

    International audienceAsteroid 2023 CX1 was discovered by KrisztiĂĄn SĂĄrneczky of Konkoly Observatory on February 12, 2023, only 7 hours before it encountered the Earth, which made it possible to track it and calculate its orbit veryprecisely. The potential strewnfield was determined in parallel by several groups and quickly released (e.g.:https://www.imo.net/the-atmospheric-trajectory-of-2023-cx1-and-the-possible-meteorite-strewn-field/). TheFRIPON/Vigie-ciel collaboration quickly mobilized its network to set up a field search campaign. An initial team ofresearchers and amateur enthusiasts met on the morning of February 15 in the fall zone identified by the international teams. On the programme: information for local resident access authorizations, meetings with mayors, scouting out favorable sites, and initial field research. At 4:47 pm on February 15 the eyes of LoĂŻs Leblanc, an 18-year-old art school student and member of the FRIPON/Vigie-Ciel team, were caught by a dark stone barely above the ground in a field located in the commune of Saint-Pierre-le-Viger (Seine Maritime), soon identified as the meteorite that we were searching for. The stone weighed 94 g and, during the following days and weeks, 10 more stones, weighing between 2 and 24 g, completed our harvest of extraterrestrial matter

    FRIPON: A worldwide network to track incoming meteoroids

    Context. Until recently, camera networks designed for monitoring fireballs worldwide were not fully automated, implying that in case of a meteorite fall, the recovery campaign was rarely immediate. This was an important limiting factor as the most fragile - hence precious - meteorites must be recovered rapidly to avoid their alteration. Aims. The Fireball Recovery and InterPlanetary Observation Network (FRIPON) scientific project was designed to overcome this limitation. This network comprises a fully automated camera and radio network deployed over a significant fraction of western Europe and a small fraction of Canada. As of today, it consists of 150 cameras and 25 European radio receivers and covers an area of about 1.5 × 106km2. Methods. The FRIPON network, fully operational since 2018, has been monitoring meteoroid entries since 2016, thereby allowing the characterization of their dynamical and physical properties. In addition, the level of automation of the network makes it possible to trigger a meteorite recovery campaign only a few hours after it reaches the surface of the Earth. Recovery campaigns are only organized for meteorites with final masses estimated of at least 500 g, which is about one event per year in France. No recovery campaign is organized in the case of smaller final masses on the order of 50 to 100 g, which happens about three times a year; instead, the information is delivered to the local media so that it can reach the inhabitants living in the vicinity of the fall. Results. Nearly 4000 meteoroids have been detected so far and characterized by FRIPON. The distribution of their orbits appears to be bimodal, with a cometary population and a main belt population. Sporadic meteors amount to about 55% of all meteors. A first estimate of the absolute meteoroid flux (mag &lt; -5; meteoroid size ≄∌1 cm) amounts to 1250/yr/106km2. This value is compatible with previous estimates. Finally, the first meteorite was recovered in Italy (Cavezzo, January 2020) thanks to the PRISMA network, a component of the FRIPON science project
