The effect of observation timescales on the characterisation of extreme Mediterranean precipitation
2018
Abstract. This paper analyses the behaviour of five rainfall indicators (maximum intensity, cumulative rainfall, irregularity, probability of rain and persistence of rain) over different observation timescales ranging from 5 min to 24 h. It covers a large area on the Mediterranean side of the Iberian Peninsula (River Júcar Water Authority, 43 000 km2) on a continuous basis over a period of 14 years (1994–2007). The results show that the behaviour of extreme Mediterranean rainfall is heavily dependent on the observation timescale. There are a number of turning points in the indicator trends which occur on different timescales (1 and 6 h in the case of rain intensity and irregularity, 6 h for…
Polysaccharide remains in Maya mural paintings: is it an evidence of the use of plant gums as binding medium of pigments and additive in the mortar?
2020
A number of monosaccharides characteristic of plant gums were found in paint layers and preparation layers of samples of Maya mural paintings of 10 archaeological sites located in Campeche and Yucatan regions. This finding opens the question about the deliberate use of these organic polymers as additives for improving workability and mechanical properties in the preparation layer mortar and conferring cohesion to the pigments in the paint layer. The study performed by GC-MS has confirmed the presence, in significant amounts, of a series of monosaccharides, being glucose and mannose between the most abundantly found. Nevertheless, the low amount present in most of the samples hindered the qu…
A (des)confiança dos jornalistas espanhóis às instituições públicas a partir do estudo de fatores organizacionais
2016
Existe un creciente interés en la bibliografía científica por conocer las prácticas y rutinas de las y los periodistas en distintos contextos (Hanitzsch et al., 2011). La confianza que tienen estos profesionales en las instituciones públicas es una variable clave para comprender su cultura profesional (Hanitzsch & Berganza, 2012; Brants, de Vreese, Möller & van Praag, 2010; van Dalen, Albæk & de Vreese, 2011), así como el interés y la confianza de la ciudadanía en la política (Cappella & Jamieson, 1997). Este estudio pretende conocer el nivel de confianza de las y los periodistas españoles en las instituciones públicas y verificar si el tipo, alcance y propiedad del medio influyen en dichos…
Leggere il diritto nella prospettiva del genere e viceversa
2021
Il contributo illustra uno dei filoni tematici del volume di O. Cavallar e J. Kirshner, ovvero il ruolo del genere nell���ordine giuridico, e sottolinea l���importanza del diritto per affrontare la storia delle identit�� di genere e soprattutto per promuovere la storia della mascolinit��.
Chlorine as a Discriminant Element to Establish the Provenance of Central Mediterranean Obsidians
2020
Abstract Chlorine is a minor element present in obsidians in quantities greater than in average igneous rocks. The chlorine concentration in obsidians is generally low, of the order of tenths of wt %, but it exhibits an appreciable differentiation among geological sources. Despite these characteristics, chlorine has rarely been taken into consideration as a possible indicator of obsidian provenance and it does not appear in the chemical analytical tables accompanying the geochemical characterisation of obsidian samples. In this work, after an overview of chlorine geochemistry and cycle, we present thirty-one new electron microprobe (EPMA) analyses, including Cl, of geologic obsidians sample…
Sensitivity of precipitation forecasts to convective parameterization in the October 2007 Flash Flood in the Valencia Region (Eastern Spain)
2018
Abstract. The Valencia region, on the Mediterranean coast of the Iberian Peninsula, is an area prone to torrential rains, especially the north of Alicante province and the south of Valencia province. In October 2007, a torrential rain event with accumulated rainfall values exceeding 400 mm in less than 24 h affected the aforementioned areas, producing flash floods that caused extensive economic losses and human casualties. Several simulations of this rain event have been performed with the Regional Atmospheric Modeling System (RAMS) to test the influence of the different convective parameterization scheme implemented in the model on the precipitation forecast.
Middle Palaeolithic flint procurement in Central Mediterranean Iberia: IMplications for human mobility.
2014
Different flint types from the Middle Palaeolithic site of Abrigo de la Quebrada (Chelva, Valencia) are characterized, both macro- and microscopically, and compared with types found at other localities in the region. Although procurement predominantly concerned the immediate vicinity of sites, our results show the presence of the same types in assemblages separated by distances of up to 120 km. The long distances involved are suggestive of a pattern of North-South mobility of human groups along the coastline of central Mediterranean Iberia.
