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…

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…

La interacción cooperativa: condición social de aprendizaje

2003

No cabe duda de que la naturaleza de la práctica educativa es fundamentalmente social, un proceso en el que las personas discurren e interactúan mutuamente como parte de una red de influencias sociales definidas y deliberadas: «[ ... ] la educación es la revelación de los demás, de la condición humana como concierto de complicidades irremediables» (Savater 2001: 35). Sin embargo, al ser la educación un tipo de interacción social intencional, no se puede dejar de destacar que la forma en que se organiza esta interacción en los procesos sociales con fines formativos, como los que ocurren en la escuela, tenga consecuencias importantes en los resultados del aprendizaje, es decir, en los proceso…

Heading identity: a question among italian postwar immigrants in the city of Mar del Plata, Argentine

2015

Este trabajo analiza, a partir de los testimonios personales ofrecidos por un grupo de inmigrantes de la posguerra, el significado que estos sujetos históricos le han dado y le dan al concepto de identidad. En tal sentido, se ha buscado rastrear a través de entrevistas orales, cuál es el sentimiento de los inmigrantes con respecto a su identidad: se sienten ¿inmigrantes? ¿Extranjeros?, ¿Argentinos? Se parte de la idea de identidad como una construcción en la que es necesario comprender no sólo en su relación con el otro sino también como una alteridad propia. Por lo tanto, la identidad de muchos inmigrantes podría caracterizarse como una “identidad partida”, es decir, dividida en dos, entre…

Michelangelo Buonarroti: the distinguished homoeroticism

2018

En este artículo, proponemos una aproximación crítica a la producción lírica de Miguel Ángel Buonarroti, a partir de un dispositivo conceptual al que denominaremos “homoerotismo distinguido”. Durante la primera mitad del siglo XVI, la obra poética de Miguel Ángel Buonarroti permite recorrer las principales motivaciones culturales y estéticas que el movimiento humanista había desplegado, entre la Florencia de los Médici y la Roma de los papas. En este trabajo se propone una lectura crítica de algunos textos de sus Rimas que apuntan decididamente a la postulación de una poética personal del gran artista, basada en el idealismo platónico y en formas expresivas no del todo canónicas. In this pa…

Hernández, Esther. Lexicografía hispano-amerindia 1550-1800. Catálogo descriptivo de los vocabularios del español y las lenguas indígenas americanas.…

2019

Publicado como el volumen 9 de la colección “Lingüística misionera” de la editorial Iberoamericana, Esther Hernández nos ofrece un completo “catálogo descriptivo de los vocabularios del español y las lenguas indígenas americanas”, tal como reza el subtítulo, que registra las obras lexicográficas correspondientes entre 1550 y 1800. Si bien la etiqueta de “lingüística” puesta a la práctica lexicográfica (y gramaticográfica) de los misioneros en la época colonial es ciertamente polémica —como lo recuerda Wulf Oesterreicher en un artículo póstumo aparecido recientemente—, esta se ha ido convirtiendo en las últimas décadas en un importante objeto de estudio sistemático, lo que se muestra tanto …

The high five: Associations of the five positive factors with the big five and well-being

2017

The study of individual differences in positive characteristics has mainly focused on moral traits. The objectives of this research were to study individual differences in positive characteristics from the point of view of the layperson, including non-moral individual characteristics, and to generate a replicable model of positive factors. Three studies based on a lexical approach were conducted. The first study generated a corpus of words which resulted in a refined list of socially shared positive characteristics. The second study produced a five-factor model of positive characteristics: erudition, peace, cheerfulness, honesty, and tenacity. The third study confirmed the model with a diff…
