Diseño y desarrollo de una interfaz para la simplificación automática de textos

La actual sociedad de la información obliga a que todos seamos capaces de acceder y comprender la información que Internet nos proporciona. Sin embargo, son muchas las personas que por muchos motivos, edad, discapacidad, aprendizaje de una lengua etc. no pueden llevar a cabo este acceso de la misma manera que la gran mayoría de las personas. Por ello es necesario disponer de entornos intuitivos y accesibles que permitan superar esta barrera. La tarea del alumno consistirá en diseñar una interfaz adecuada a las necesidades de cada usuario, que permita obtener versiones simplificadas y/o enriquecidas del texto deseado. Para ello el alumno se acercará al mundo de las tecnologías del lenguaje humano y a las herramientas que dicha tecnología proporciona para incorporar aquellas que resulten más adecuadas a los objetivos fijados

Dynamical and temporal characterization of the total ozone column over Spain

As the ozone is one of the most relevant variables in the climate system, to get further in its long-term characterization is a critical issue. In this study, measurements of total ozone column (TOC) from five well-calibrated Brewer spectrophotometers placed in the Iberian Peninsula are analyzed. The temporal trend rate for TOC is +9.3 DU per decade for the period 1993–2012 in Central Iberian Peninsula. However, the low TOC levels during 2011 and 2012 over the study region notably reduce this rate. Empirical linear relationships are established between TOC and pressure, height, and temperature of the tropopause. The linear fits showed seasonal and latitudinal dependence, with stronger relationships during winter and spring. Events with the presence of a double tropopause (DT) are proved to be characteristic of the study region. The decrease in TOC levels when these anomalous events occur is quantified around 10 % in winter and spring with respect to the usual cases with a single tropopause. The total weight of the DT events with respect to the annual values is about 20 %, with a negligible occurrence in summer and autumn and being latitudinal-dependent. The North Atlantic Oscillation (NAO) index explains 30 % of the total ozone variability in winter. The DT events are found to be more frequent during phases with positive NAO.This work was partially supported the Ministerio de Ciencia e Innovación through project CGL2011-29921-C02-01

Effects of Methyl Jasmonate and Nano-Methyl Jasmonate Treatments on Monastrell Wine Volatile Composition

This work has been supported by funding provided by the Spanish MCIN/AEI/10.13039/501100011033 and "ERDF, A way of making Europe" through the projects NanoVIT (RTI-2018-095794-B-C21 and RTI-2018-095794-A-C22), and by the Junta de Andalucia with the project NanoFERTi (P18-TP-969). GBRR also acknowledges Junta de Andalucia for her postdoctoral contract within the PAIDI 2020 program (DOC_01383).The application of methyl jasmonate (MeJ) as an elicitor to enhance secondary metabolites in grapes and wines has been studied, but there is little information about its use in conjunction with nanotechnology and no information about its effects on wine volatile compounds. This led us to study the impact of nanoparticles doped with MeJ (Nano-MeJ, 1mM MeJ) on the volatile composition of Monastrell wines over three seasons, compared with the application of MeJ in a conventional way (10 mM MeJ). The results showed how both treatments enhanced fruity esters in wines regardless of the vintage year, although the increase was more evident when grapes were less ripe. These treatments also achieved these results in 2019 in the cases of 1-propanol, ß-phenyl-ethanol, and methionol, in 2020 in the cases of hexanol and methionol, and in 2021, but only in the case of hexanol. On the other hand, MeJ treatment also increased the terpene fraction, whereas Nano-MeJ, at the applied concentration, did not increase it in any of the seasons. In summary, although not all families of volatile compounds were increased by Nano-MeJ, the Nano-MeJ treatment generally increased the volatile composition to an extent similar to that obtained with MeJ used in a conventional way, but at a 10 times lower dose. Therefore, the use of nanotechnology could be a good option for improving the quality of wines from an aromatic point of view, while reducing the necessary dosage of agrochemicals, in line with more sustainable agricultural practices.Junta de Andalucia P18-TP-969 DOC_01383Spanish MCIN/AEI"ERDF, A way of making Europe" through the projects NanoVIT RTI-2018-095794-B-C21 RTI-2018-095794-A-C2

Comparison of GOME-2/MetOp total ozone data with Brewer spectroradiometer data over the Iberian Peninsula

The main objective of this article is to compare the total ozone data from the new Global Ozone Monitoring Experiment instrument (GOME-2/MetOp) with reliable ground-based measurement recorded by five Brewer spectroradiometers in the Iberian Peninsula. In addition, a similar comparison for the predecessor instrument GOME/ERS-2 is described. The period of study is a whole year from May 2007 to April 2008. The results show that GOME-2/MetOp ozone data already has a very good quality, total ozone columns are on average 3.05% lower than Brewer measurements. This underestimation is higher than that obtained for GOME/ERS-2 (1.46%). However, the relative differences between GOME-2/MetOp and Brewer measurements show significantly lower variability than the differences between GOME/ERS-2 and Brewer data. Dependencies of these relative differences with respect to the satellite solar zenith angle (SZA), the satellite scan angle, the satellite cloud cover fraction (CF), and the ground-based total ozone measurements are analyzed. For both GOME instruments, differences show no significant dependence on SZA. However, GOME-2/MetOp data show a significant dependence on the satellite scan angle (+1.5%). In addition, GOME/ERS-2 differences present a clear dependence with respect to the CF and ground-based total ozone; such differences are minimized for GOME-2/MetOp. The comparison between the daily total ozone values provided by both GOME instruments shows that GOME-2/MetOp ozone data are on average 1.46% lower than GOME/ERS-2 data without any seasonal dependence. Finally, deviations of a priori climatological ozone profile used by the satellite retrieval algorithm from the true ozone profile are analyzed. Although excellent agreement between a priori climatological and measured partial ozone values is found for the middle and high stratosphere, relative differences greater than 15% are common for the troposphere and lower stratosphere.This work was partially supported by Ministerio de Educacion y Ciencia under project CGL2005-05693-C03-03/CLI and by Ministerio de Ciencia e Innovacion under project CGL2008-05939-C03-02/CLI
