Tethyan vs. Cordilleran ophiolites: a reappraisal of distintctive tectono-magmatic features of supra-subduction complexes in relation to the subducti…
2004
Abstract Supra-subduction zone (SSZ) ophiolites deserve special attention because they represent fundamental markers of intraoceanic convergence and generation of new lithosphere above subduction zones. Moreover, owing to their structural characteristics and location in the overriding plate, these complexes are far better represented and preserved than Mid-Ocean-Ridge-Basalt (MORB) ophiolites in orogenic belts. In terms of their structure, tectonics, and magmatic features, SSZ ophiolites may be classified in two main types: (1) “Tethyan complexes” (such as those of the Albanide-Hellenide belt), which mostly consist of complete and extensive volcanic, dyke, plutonic, and mantle sections with…
The use of soil water retention curve models in analyzing slope stability in differently structured soils
2017
Abstract This study analyzes whether and at what rate the parameterization of the Soil Water Retention Curve (SWRC) affects the analysis of shallow slope stability for differently structured unsaturated soils. Advanced empirical or physically-based equations of SWRCs have been proposed in literature to describe soil systems characterized by the so-called bimodal porous domain. In unsaturated soils, SWRC affects the stability assessment in two ways. It influences the resistance properties in terms of shear strengths, which depend on the soil water suction; and it affects the hydrological process modeling (e.g. infiltration) directly influencing soil moisture patterns and indirectly influenci…
La distribución espacial de hogares perceptores de prestaciones económicas individualizadas: una comparación de casos
2021
El análisis de las desigualdades socioespaciales ha constituido una línea de investigación destacada en el ámbito de las ciencias sociales. No obstante, la cuestión de la desigual proyección territorial de las políticas sociales en el interior de las ciudades ha recibido una menor atención académica. En este artículo se analizan, desde una perspectiva comparada, los patrones de distribución espacial de los hogares perceptores de Prestaciones Económicas Individualizadas (PEI) en dos municipios de la Comunidad Valenciana (España): Bétera y Torrent. Para ello, se implementan distintas técnicas de análisis de puntos espaciales y de Análisis Exploratorio de Datos Espaciales (AEDE). Los resultado…
Conflictos y desarrollos del imaginario colectivo: el paisaje de la Albufera y el Saler
2017
La Dehesa del Saler forma parte de la Albufera, el espacio más problemático y al mismo tiempo, el más emblemático del patrimonio paisajístico valenciano. Su análisis no podría estar separado de una construcción histórica polifónica, tejida por un lado por los múltiples discursos que forman la historia del espacio real, humano y paisajístico y, a la vez, por aquellas voces que configuran un imaginario cultural con fuertes valores identitarios. The Dehesa of the Saler forms a part of the Albufera lagoon, the most problematic, and in the same time, the most emblematic space of the Valencian landscape heritage. Its analysis might not be separated from a historical polyphonic construction, woven…
Vivienda pública y estado de bienestar en España: balance y estado de la cuestión en la época del COVID-19
2021
La presente investigación se centra en analizar la trayectoria de la política pública de vivienda en España para el periodo 1956-2020 enfatizando en la emergencia social y habitacional a lo largo de sesenta años al objeto de introducir la coyuntura actual y los retos futuros en el escenario post pandemia. Para ello, se ha realizado una búsqueda exhaustiva en bases de datos jurídicas a partir de la especificación de una serie de descriptores analíticos, así como la búsqueda en fuentes secundarias de tipo bibliográfico y estadístico. El artículo profundiza en la trayectoria de la política pública de vivienda a través de los distintos marcos de actuación a lo largo de sesenta años, su comparat…
Effects of simulated environmental changes on growth and growth form in a late snowbed population of pohlia wahlenbergii (Web. et Mohr) Andr
2003
In a factorial field experiment we increased the temperature (Open Top Chambers) and nutrients (nitrogen, phosphorus, and potassium [NPK]) to simulate predicted future climate changes and studied the growth response of the acrocarpous bryophyte Pohlia wahlenbergii (Bryaceae) in a wet snowbed environment. The species shows a positive growth-length response to added nutrients and increased temperature. The stronger response to nutrients indicates a strong limitation of nutrients in the snowbed environment. There was an immediate response to nutrient treatment, whereas the temperature response was delayed. The growth response shows a clear interaction between temperature and nutrients. The imm…
The study of climate change in Primary Education: an exploration from Social Science textbooks in the Valencian Community
2020
El cambio climático constituye uno de los principales desafíos socio-ambientales del actual siglo XXI. El objetivo de esta investigación es analizar los contenidos sobre el cambio climático que proponen los manuales escolares de Educación Primaria de Ciencias Sociales (3er ciclo) en la Comunidad Valenciana (España) atendiendo a: 1) la explicación del fenómeno (causas y consecuencias); y 2) la descripción de los principales gases de efecto invernadero. Los resultados indican que actualmente estos recursos proyectan una imagen excesivamente catastrófica sobre el cambio climático, especialmente por las consecuencias que se aluden (incremento de los fenómenos extremos atmosféricos) y citando co…
A Kalman filter single point positioning for maritime applications using a smartphone
2020
Different positioning techniques have been largely adopted for maritime applications that require high accuracy kinematic positioning. The main objective of the paper is the performance assessment of a Single Point Positioning algorithm (SPP), with a Kalman filter (KF) estimator, adapted for maritime applications. The KF has been chosen as estimation technique due to the ability to consider both the state vector dynamic and the measurements. Particularly, in order to compute an accurate vertical component of the position, suitable for maritime applications, the KF settings have been modified by tuning the covariance matrix of the process noise. The algorithm is developed in Matlab environme…

La ville, la raison et le rêve : entre théorie et utopie
1996
City, reason and dream : between theory and utopia. — This paper aims at comparing two kinds of discourses about the city, that of the microeconomics of cities, which is admitted in the realm of science, and that of Utopian cities, which is not. We analyse the processes of thinking which lead respectively to theory and utopia, then we compare the ideas of man and society upon which they are grounded. Finaly, we try to enhance the similarities and disimilarities between the two series of urban space representations to which these approaches lead. This comparison may contribute to a better understanding of the real nature of the theoretical discourse and lead both to a relativization and a va…
