La formation en sciences pharmaceutiques, des réformes successives
2019
EnglishIn France, healthcare studies are regulated on a national level. Pharmacy degrees are subjected to numerous decrees and laws setting out the different modifications brought about by successive reforms. The process to adapt this degree course is far from finished. francaisEn France, les etudes de sante sont reglementees au niveau national. La formation pharmaceutique a fait l’objet de nombreux decrets et arretes fixant les differentes modifications induites par les reformes successives
La aporofobia como desafío antropológico. De la lógica de la cooperación a la lógica del reconocimiento
2019
el objetivo de este trabajo es poner en relación el núcleo crítico de la última obra de Adela Cortina, Aporofobia, que puede ser resu- mido como una protesta contra los límites del paradigma de la cooperación y la reciprocidad, con algunos elementos aparecidos en obras ante- riores de la autora 1 . Para ello expondré primero algunos límites y virtualidades del paradigma de la reciprocidad. Tras bosquejar el núcleo de la obra Aporofobia, deteniéndome en los lugares en que este problema se hace más patente, terminaré rastreando algunos lugares anteriores en los que la autora anticipaba ya, desde una óptica diferente, esta misma crítica. he aim of this paper is to connect the critical core of …

Ten millennia of hepatitis B virus evolution
2021
Hepatitis B virus (HBV) has been infecting humans for millennia and remains a global health problem, but its past diversity and dispersal routes are largely unknown. We generated HBV genomic data from 137 Eurasians and Native Americans dated between ~10,500 and ~400 years ago. We date the most recent common ancestor of all HBV lineages to between ~20,000 and 12,000 years ago, with the virus present in European and South American hunter-gatherers during the early Holocene. After the European Neolithic transition, Mesolithic HBV strains were replaced by a lineage likely disseminated by early farmers that prevailed throughout western Eurasia for ~4000 years, declining around the end of the 2nd…
Dependence of polytetrafluoroethylene reflectance on thickness at visible and ultraviolet wavelengths in air
2020
[EN] Polytetrafluoroethylene (PTFE) is an excellent diffuse reflector widely used in light collection systems for particle physics experiments. However, the reflectance of PTFE is a function of its thickness. In this work, we investigate this dependence in air for light of wavelengths 260 nm and 450 nm using two complementary methods. We find that PTFE reflectance for thicknesses from 5 mm to 10 mm ranges from 92.5% to 94.5% at 450 nm, and from 90.0% to 92.0% at 260 nm We also see that the reflectance of PIFE of a given thickness can vary by as much as 2.7% within the same piece of material. Finally, we show that placing a specular reflector behind the PTFE can recover the loss of reflectan…
Electron drift properties in high pressure gaseous xenon
2018
[EN] Gaseous time projection chambers (TPC) are a very attractive detector technology for particle tracking. Characterization of both drift velocity and di¿usion is of great importance to correctly assess their tracking capabilities. NEXT-White is a High Pressure Xenon gas TPC with electroluminescent ampli¿cation, a 1:2 scale model of the future NEXT-100detector, which will be dedicated to neutrinoless double beta decay searches. NEXT-White has been operating at Canfranc Underground Laboratory (LSC) since December2016. The drift parameters have been measured using 83mKr for a range of reduced drift ¿elds at two di¿erent pressure regimes, namely 7.2 bar and 9.1 bar. Theresults have been comp…
The Next White (NEW) detector
2018
[EN] Conceived to host 5 kg of xenón at a pressure of 15 bar in the ¿ducial volume,the NEXTWhite (NEW)apparatus is currently the largest high pressure xenon gas TPC using electroluminescent ampli¿cation in the world. It is also a 1:2 scale model of the NEXT-100 detector scheduled to start searching for ßß0¿ decays in 136Xe in 2019. Both detectors measure the energy of the event using a plane of photomultipliers located behind a transparent cathode. They can also reconstruct the trajectories of charged tracks in the dense gas of the TPC with the help of a plane of silicon photomultipliers located behind the anode. A sophisticated gas system, common to both detectors, allows the high gas puri…
