Wide-scope screening of pharmaceuticals, illicit drugs and their metabolites in the Amazon River.
2021
Only a limited number of households in the Amazon are served by sewage collection or treatment facili- ties, suggesting that there might be a significant emission of pharmaceuticals and other wastewater contaminants into freshwater ecosystems. In this work, we performed a wide-scope screening to assess the occurrence of pharmaceuticals, illicit drugs and their metabolites in freshwater ecosystems of the Brazilian Amazon. Our study included 40 samples taken along the Amazon River, in three of its major tributaries, and in small tributaries crossing four important urban areas (Manaus, Santarém, Macapá, Belém). More than 900 compounds were investigated making use of target and suspect screenin…
Preventing Violence and Social Exclusion through Sport and Physical Activity: The SAVE Project
2018
Sport Against Violence and Exclusion (SAVE), a project cofounded by the Erasmus + Program of the European Union, seeks to prevent violent and socially exclusive behaviors through physical activity. The current editorial shows a range of possible interpretations of these two phenomena from both a psychological and sociological point of view, offering helpful methods to coaches who train children (ages 6 to 12)in grass-root sport clubs. Following a thorough analysis, partners from seven EU countries (Lithuania, Italy, Croatia, Bosnia and Herzegovina, Serbia, Austria, and Spain) will be able to identify skills and techniques for coaches to ensure inclusive training methods as well as to provid…
Cronología bayesiana aplicada a las intervenciones de Lluís Pericot en Cueva de la Cocina (1941 y 1945)
2017
Este capítulo tiene como objetivo la comprensión de la estratigrafía en Cueva de la Cocina, y más en concreto de las intervenciones realizadas por Pericot en el año 1941 y 1945. Para ello se hará uso del conjunto de dataciones radiocarbónicas disponibles para dichas intervenciones sobre las que se elaborarán diferentes modelos cronológicos a partir de la estadística bayesiana. Finalmente sobre los resultados de la modelización cronológica se discierne en torno a la ocupación mesolítica de la cueva a lo largo del Mesolítico reciente (entidad arqueológica conocida como Mesolítico geométrico), haciendo hincapié en las diferentes fases culturales (Geométrico A y B) y sus rangos cronológicos.

Virtual Tours as Emerging Technologies to Engage Children and Youth with their Country’s Historical Conflicts
2022
Virtual Reality (VR) is increasingly used for visiting historic places. Research on VR experiences in dark tourism (that focuses on mortality) focuses almost exclusively on adults. No studies were found that used virtual tours to engage children with their own country’s conflicts. The present study addresses this gap by designing and developing virtual tours in four cities of Europe with a troubled past. Virtual tours engage children and youth in historical conflicts using multi-perspective storytelling. The aim of this pre-test post-test comparative case study is to examine the change on students’ perceptions of their country’s troubled past after their interaction with a virtual tour of t…
Full field of view super-resolution imaging via two static masks
2008
The usage of two static gratings for obtaining super resolved imaging dates back to the work by Bachl and Lukosz in 1967. However, in that approach, a severe reduction in the field of view was the necessary condition for improving the resolution. In this paper we present two approaches that are also based upon two static gratings but without the need to sacrifice in the field of view. The key idea for not paying with the field of view is performed in two ways: First, by using white light illumination that averages the ghost images obtained outside the region of interest since the positions of those images are wavelength dependent. Second, by using two random functions for the encoding and t…
Recent results on heavy-ion induced reactions of interest for neutrinoless double beta decay at INFN-LNS
2019
Abstract The NUMEN project aims at accessing experimentally driven information on Nuclear Matrix Elements (NME) involved in the half-life of the neutrinoless double beta decay (0νββ). In this view measurements of Heavy Ion (HI) induced Double Charge Exchange (DCE) reaction cross sections are performed with high-accuracy. In particular, the (18O,18Ne) and (20Ne,20O) reactions are used as tools for β+β+ and β-β- decays, respectively. In the experiments, performed at INFN - Laboratory Nazionali del Sud (LNS) in Catania, the beams are accelerated by the Superconducting Cyclotron (CS) and the reaction ejectiles are detected the MAGNEX magnetic spectrometer. The measured cross sections are challe…
Explotació dels mamífers i economia de les darreres comunitats caçadores-recol·lectores del vessant mediterrani ibèric durant la transició Tardiglaci…
2015
En el presente trabajo se realiza el estudio zooarqueológico de los vertebrados terrestres explotados por los grupos humanos de los niveles tardiglaciares de los yacimientos de Santa Maira (boca Oeste) y Nerja (sala del Vestíbulo). A partir de los datos obtenidos para las facies culturales Magdaleniense / Epipaleolítico / Mesolítico se caracterizan las tendencias de cambio en los modelos económicos de las últimas comunidades cazadoras-recolectoras de la península ibérica. Estas secuencias se contextualizan así mismo en la zona biogeográfica mediterránea peninsular. Entre los resultados obtenidos cabe destacar la definición y caracterización de un modelo económico "tardiglaciar", donde el mo…
High Resolution Study of the v1 + 2v2 −v2 and 2v2 + v3 − v2 ”Hot” Bands and Ro-Vibrational Re-Analysis of the v1 + v2/v2 + v3/3v3 Poliad of the SO2 M…
2010
The main goal of the present study was to analyse rotational stuctures of two excited vibrational states, (120) and (021). Because both the band, v1+2v2 and 2v2+v3 one are extremally weak, a special efforts were faired to record very weak hot bands, v1+2v2−v2 and 2v2+v3−v2.Both of those bands are located in the region of considerably more stronger combinational bands, v1 + v2 and v2 + v3. On that reason, as the first step of analysis, we made assignments of transitions belonging to these v1 + v2 and v2 + v3 bands. As the result of analysis, we were able to assign three times more transitions to the bands v1 + v2 and v2 + v3 than it was known in the before literature. After "cleaning" the ex…
Magnetic Resonance Microscopy Contribution to Interpret High-Resolution Magic Angle Spinning Metabolomic Data of Human Tumor Tissue
2010
[EN] HRMAS NMR is considered a valuable technique to obtain detailed metabolic profile of unprocessed tissues. To properly interpret the HRMAS metabolomic results, detailed information of the actual state of the sample inside the rotor is needed. MRM (Magnetic Resonance Microscopy) was applied for obtaining structural and spatially localized metabolic information of the samples inside the HRMAS rotors. The tissue was observed stuck to the rotor wall under the effect of HRMAS spinning. MRM spectroscopy showed a transference of metabolites from the tissue to the medium. The sample shape and the metabolite transfer after HRMAS indicated that tissue had undergone alterations and it can not be s…
Resolution of β-aminophosphines with chiral cyclopalladated complexes
2005
Abstract Resolution of the racemic chiral β-aminophosphines Ph 2 PCH 2 CH(Ph)NH(Ar) ( L 1 for Ar = C 6 H 5 and L 2 for Ar = 2,6-C 6 H 3 i Pr 2 ) has been investigated by use of different cyclopalladated complexes as chiral agents. The resulting complexes afford diastereomeric adducts in a 1:1 ratio. After successive crystallizations from ethanol, a d.e. of 98% was achieved for one aminophosphine palladium complex, while no significant d.e. was obtained after crystallizations from chlorinated solvents. The X-ray structure analysis has pointed out intermolecular hydrogen interactions N–H⋯Cl between the P,N ligand and the chloride ion, which are responsible for the formation and stabilization …
