O projeto Mujeres Maestras del Perú. Estudo de caso sobre identidades de ensino
2018
El proyecto «Mujeres Maestras de Perú» nos acerca a las opiniones de veintiun maestras peruanas. Las que trabajan en entornos menos favorecidos e insisten en su precocidad vocacional. Las maestras nos hablan de dicho factor vocacional como de algo que ya aparece en su infancia en tanto que deseo explícito de dedicarse a la docencia. Nuestra investigación parte de un enfoque cualitativo, mediante un estudio de caso al que incorporamos elementos de rango artístico (Investigación basada en las artes). Utilizamos grabaciones audiovisuales como instrumento de recogida de datos. Desde la educación artística, visibilizamos las identidades del colectivo docente como homenaje y reivindicación profes…

An X-ray characterization of the central region of the supernova remnant G332.5-5.6
2015
Aims. We present an X-ray analysis of the central region of supernova remnant (SNR) G332.5-5.6 through an exhaustive analysis of XMM-Netwon observations with complementary infrared observations. We characterize and discuss the origin of the observed X-ray morphology, which presents a peculiar plane edge over the west side of the central region. Methods. The morphology and spectral properties of the X-ray SNR were studied using a single full frame XMM-Netwon observation in the 0.3 to 10.0 keV energy band. Archival infrared WISE observations at 8, 12 and 24 μm were also used to investigate the properties of the source and its surroundings at different wavelengths. Results. The results show th…
Photografted methacrylate-based monolithic columns coated with cellulose tris(3,5-dimethylphenylcarbamate) for chiral separation in CEC
2018
A chiral capillary monolithic column for enantiomer separation in capillary electrochromatography was prepared by coating cellulose tris(3,5-dimethylphenylcarbamate) on porous glycidyl methacrylate-co-ethylene dimethacrylate monolith in capillary format grafted with chains of [2(methacryloyloxy)ethyl] trimethylammonium chloride. The surface modification of the monolith by the photografting of [2(methacryloyloxy)ethyl] trimethylammonium chloride monomer as well as the coating conditions of cellulose tris(3,5-dimethylphenylcarbamate) onto the grafted monolithic scaffold were optimized to obtain a stable and reproducible chiral stationary phase for capillary electrochromatography. The effect o…
Monitoring Chemical Reactions with SERS-Active Ag-Loaded Mesoporous TiO2 Films
2020
Monitoring chemical reactions that occur in small spaces or confined environments is challenging. Surface-enhanced Raman scattering (SERS) spectroscopy offers the unique possibility to monitor spectral changes with high sensitivity and time resolution. Herein, we report the application of composite mesoporous TiO2 films loaded with Ag nanoparticles (NPs) to track in situ chemical processes in real time. In particular, the AgNPs@TiO2 system was employed to monitor two chemical reactions: one occurring on the Ag NPs surface and another taking place in the surrounding solution. In the first case, we monitored the decarboxylation reaction of 4-mercaptobenzoic acid on Ag NPs, which allowed us to…
Monitoring and data quality assessment of the ATLAS liquid argon calorimeter
2014
The liquid argon calorimeter is a key component of the ATLAS detector installed at the CERN Large Hadron Collider. The primary purpose of this calorimeter is the measurement of electron and photon kinematic properties. It also provides a crucial input for measuring jets and missing transverse momentum. An advanced data monitoring procedure was designed to quickly identify issues that would affect detector performance and ensure that only the best quality data are used for physics analysis. This article presents the validation procedure developed during the 2011 and 2012 LHC data-taking periods, in which more than 98% of the proton-proton luminosity recorded by ATLAS at a centre-of-mass ener…
Aikuisten S2-oppijoiden kielenoppimisen kokemuksia selkomukautetun kaunokirjallisuuden parissa
2020
Artikkeli käsittelee oppimisen kokemuksia selkomukautetun kaunokirjallisuuden parissa kotoutumiskoulutuksen lukupiirissä. Aineistona ovat lukupiirien 24 osallistujan haastattelut. Haastattelut on tehty osallistujien toisella kielellä tai lingua franca -englannilla, ja niitä lähestytään fenomenologista ajattelutapaa hyödyntäen kertomuksina oppimisen kokemuksista. Kokemukset vaihtelevat yksilöllisesti, ja tärkeimmiksi merkityskokonaisuuksiksi nousevat sanat, kielen rakenteet ja kielenkäyttö. Kokemusten yksilöllisyyttä voidaan selittää sosiokulttuurisesta teoriasta käsin: vaikka selkomukautettu kaunokirjallisuus tarjoaa lukijalleen runsaasti kielellisiä affordansseja, tarjoumia, kukin lukija t…
An updated insight into the Sialotranscriptome of Triatoma infestans: developmental stage and geographic variations
2014
Background Triatoma infestans is the main vector of Chagas disease in South America. As in all hematophagous arthropods, its saliva contains a complex cocktail that assists blood feeding by preventing platelet aggregation and blood clotting and promoting vasodilation. These salivary components can be immunologically recognized by their vector's hosts and targeted with antibodies that might disrupt blood feeding. These antibodies can be used to detect vector exposure using immunoassays. Antibodies may also contribute to the fast evolution of the salivary cocktail. Methodology Salivary gland cDNA libraries from nymphal and adult T. infestans of breeding colonies originating from different loc…
Interpersonal dynamics in 2-vs-1 contexts of football: the effects of field location and player roles
2019
This study analyzed the spatial-temporal interactions that sustained 2-vs-1 contexts in football at different field locations near the goal. Fifteen male players (under 15 years, age 13.2 ± 1.03 years, years of practice 4.2 ± 1.10 years), 5 defenders, 7 midfielders, and 3 attackers, participated in the study. Each participant performed a game to simulate a 2-vs-1 sub-phase as a ball carrier, second attacker, and defender at three different field locations, resulting in a total number of 142 trials. The movements of participants in each trial were recorded and digitized with TACTO software. Values of interpersonal distance between the ball carrier and defender and interpersonal angles betwee…
Serial Production, Serial Photography, and the Writing of History in Three Farmers on Their Way to a Dance.
2010
Three Farmers on their Way to a Dance, titre d’une photographie qu’August Sander prit en 1914, hante le roman éponyme de Richard Powers. Cette photographie faisait partie d’un projet plus vaste, intitulé « Hommes du vingtième siècle » par Sander qui entendait dresser un inventaire des habitants de sa province natale, le Westerwald. Sander composa ainsi un catalogue de plus de 600 photos d’Allemands de tous types, dont il fit plus tard paraître une partie sous le nom de Visage de notre temps. Dans le roman de Richard Powers, le motif de la série se déploie entre les pôles incarnés par Henry Ford et August Sander, dont les séries de voitures et de photographies deviennent la métaphore du mode…
