Exploitation of SAR and Optical Sentinel Data to Detect Rice Crop and Estimate Seasonal Dynamics of Leaf Area Index
2017
This paper presents and evaluates multitemporal LAI estimates derived from Sentinel-2A data on rice cultivated area identified using time series of Sentinel-1A images over the main European rice districts for the 2016 crop season. This study combines the information conveyed by Sentinel-1A and Sentinel-2A into a high-resolution LAI retrieval chain. Rice crop was detected using an operational multi-temporal rule-based algorithm, and LAI estimates were obtained by inverting the PROSAIL radiative transfer model with Gaussian process regression. Direct validation was performed with in situ LAI measurements acquired in coordinated field campaigns in three countries (Italy, Spain and Greece). Res…
The Making of the New European Wind Atlas - Part 2: production and evaluation
2020
This is the second of two papers that document the creation of the New European Wind Atlas (NEWA). In Part 1, we described the sensitivity experiments and accompanying evaluation done to arrive at the final mesoscale model setup used to produce the mesoscale wind atlas. In this paper, Part 2, we document how we made the final wind atlas product, covering both the production of the mesoscale climatology generated with the Weather Research and Forecasting (WRF) model and the microscale climatology generated with the Wind Atlas Analysis and Applications Program (WAsP). The paper includes a detailed description of the technical and practical aspects that went into running the mesoscale simulati…
Virgin olive oil enriched with its own phenolic compounds or complemented with thyme improves endothelial function: The potential role of plasmatic f…
2017
The aim of the present study was to assess whether different functional virgin olive oils (FVOOs) with varying phenolic compounds (PC) could protect the plasmatic fat-soluble vitamins, which in turn could improve the endothelial function. In order to select the optimal phenolic dose in the improvement of ischemic reactive hyperemia (IRH), a dose-response study (n = 12, healthy subjects) was performed and the enrichment of 500 mg PC/kg oil was selected. In a 3-week cross-over sustained study (n = 33 hypercholesterolemic subjects), the consumption of 25 mL/day of two phenol-enriched olive oils (one enriched with its own PC and another combined with thyme PC) increased IRH and plasma concentra…
Polyphenol Levels Are Inversely Correlated with Body Weight and Obesity in an Elderly Population after 5 Years of Follow Up (The Randomised PREDIMED …
2017
Overweight and obesity have been steadily increasing in recent years and currently represent a serious threat to public health. Few human studies have investigated the relationship between polyphenol intake and body weight. Our aim was to assess the relationship between urinary polyphenol levels and body weight. A cross-sectional study was performed with 573 participants from the PREDIMED (Prevención con Dieta Mediterránea) trial (ISRCTN35739639). Total polyphenol levels were measured by a reliable biomarker, total urinary polyphenol excretion (TPE), determined by the Folin-Ciocalteu method in urine samples. Participants were categorized into five groups according to their TPE at the fifth …
Mediterranean Diet Improves High-Density Lipoprotein Function in High-Cardiovascular-Risk Individuals: A Randomized Controlled Trial.
2017
Background: The biological functions of high-density lipoproteins (HDLs) contribute to explaining the cardioprotective role of the lipoprotein beyond quantitative HDL cholesterol levels. A few small-scale interventions with a single antioxidant have improved some HDL functions. However, to date, no long-term, large-scale, randomized controlled trial has been conducted to assess the effects of an antioxidant-rich dietary pattern (such as a traditional Mediterranean diet [TMD]) on HDL function in humans. Methods: This study was performed in a random subsample of volunteers from the PREDIMED Study (Prevención con Dieta Mediterránea; n=296) after a 1-year intervention. We compared the effects …
Presupuestos hermenéuticos de la filosofia moral y política de Charles Taylor para una sociedad intercultural.
2009
Dos preguntas atraviesan la investigación desarrollada en el documento de la tesis doctoral: 1) ¿Qué relación guarda Taylor con la hermenéutica filosófica? 2) ¿Ahondar en dicha relación esclarece las tesis éticas y políticas de Taylor haciéndolas más defendibles?Respecto a la primera cuestión sostenemos que existe efectivamente una estrecha relación entre la filosofía de Charles Taylor y la hermenéutica filosófica. En este sentido la primera parte de la tesis "Presupuestos hermenéuticos" se encarga de ir precisando el perfil hermenéutico de su antropología filosófica. Más concretamente encontramos cuatro rasgos característicos: carácter auto-interpretativo del ser humano (capítulo 1), sí mi…

Las otras fallas: Imaginación metafórica como realidad de lo posible.
2009
Partiendo del análisis de dos obras concretas de construcciones falleras, confeccionadas en el propio taller del doctorando, y de la mano del estudio de determinadas concreciones estéticas de la imaginación metafórica, hemos pretendido esbozar el universo teórico-experimental que nos ha llevado a ser capaces de elaborar dichas obras en el espacio público de la calle, dentro del marco decidido de las otras fallas. La lucha contra las metáforas emanadas desde el Poder también puede hacerse creando otras realidades que desmonten esas virtualidad en que mayormente vivimos: o inventando pequeñas historias a medida de las personas, para contradecir la Historia que mienten l@s vencedor@s o mediant…
