Retrieving and broadcasting near-real-time biophysical parameters from MODIS and SEVIRI receiving stations at the global change unit of the Universit…
2015
We present here the automatic processing chains implemented at the Global Change Unit of the University of Valencia. These allow for a near-real-time retrieval of various biophysical parameters from both Sun-synchronous TERRA/AQUA Moderate Resolution Imaging Spectroradiometer MODIS and geostationary Meteosat Second Generation Spinning Enhanced Visible and Infrared Imager MSG SEVIRI sensors. Retrieved parameters, namely sea and land surface temperatures SST and LST, respectively, normalized difference vegetation index NDVI, and vegetation condition index VCI, are similar for both sensors, and specific approaches have been developed and implemented for near-real-time parameter retrievals: htt…
Organocatalytic Enantioselective Friedel-Crafts Alkylation of 1-Naphthol Derivatives and Activated Phenols with Ethyl Trifluoropyruvate
2015
An organocatalytic enantioselective Friedel–Crafts alkylation of a series of substituted 1- naphthol derivatives and activated phenols with ethyl trifluoropyruvate, catalyzed by a quinine-derived squaramide, is presented. Good yields and high to excellent enantioselectivities of the Friedel– Crafts alkylation products were obtained.
Detection and discrimination of organophosphorus pesticides in water by using a colorimetric probe array
2014
[EN] Detection and discrimination of several organophosphorus pesticides in water using a colorimetric probe array containing twelve dyes has been achieved. A clear discrimination for malathion, leptophos, dichlorvos, dibrom and diazinon was observed. The array was used to determine the concentration of diazinon in orange leaves
La rajola a la costa i els residus a l’interior. Mapa dels conflictes socioecològics al País Valencià
2020
EnglishIn the last decade, the Valencian Country has experimented a growth of the productive processes that has led to an unprecedented degradation of the territory. At the same time, the increase in the ecological, material and carbon footprint has led to the generation of socio-ecological conflicts. A typology of socio-ecological conflicts is proposed, consisting of 5 categories —derived from urban processes, infrastructures, pollution and public health, the extraction of mineral resources and the use of water resources—, which classifies and places them on the 'map of the socio-ecological conflicts of the Valencia Country'. The map locates such environmental conflicts. Furthermore, the u…
Análisis del efecto Airbnb en la ciudad de Valencia. Situación actual (2020) y perspectivas de futuro / / / \ \ \ Analysis of the Airbnb effect in th…
2021
Resumen: Las ciudades experimentan cambios rápidos. Uno de estos tiene como elemento disruptivo el crecimiento del turismo, es decir, de la atractividad de determinados espacios urbanos que ha dado lugar a un aumento de la oferta para los visitantes, tanto de recursos como, sobre todo, de alojamiento. Un elemento clave para explicar este aumento de la oferta es el alquiler turístico o alquiler de corta duración a través de plataformas digitales, entre las que destaca Airbnb. En la ciudad de Valencia, este fenómeno ha experimentado un crecimiento espectacular durante el segundo decenio del presente siglo. A partir de un análisis detallado de la oferta turística en los barrios de Valencia, se…
Comparison of aerosol optical thickness retrieval from spectroradiometer measurements and from two radiative transfer models
2000
Abstract The spectral values of the aerosol optical thickness τ a λ in the 400–670 nm band have been determined from 500 solar direct irradiance spectra at normal incidence registered at Valencia (Spain) in the period from July 1993 to March 1997. The τ a λ values obtained from experimental measurements have been compared with the boundary layer aerosol models implemented in the radiative transfer codes ZD-LOA and LOWTRAN 7. For the ZD-LOA code, the continental and maritime models have been considered and for the LOWTRAN 7 code the rural, maritime, urban and tropospheric models have been used. The obtained results show that the aerosol model that best represents the average turbidity of the…
La fiesta mutante. La construcción histórica de la Feria de Julio de Valencia
2014
[EN] In the present article it is tried to show as the holidays they are social historical constructions, which mutations are inseparable both of the diverse political contexts and of the institutional action. This one is the case of Julio's Fair of Valencia, founded in in 1871 under the requiriments of bourgeois taste. In our work we show, resting on historical documentation of press and file, the diverse stages of the evolution of the Fair, insisting in since there is modified his cultural institutional management. So if at firdt period of euphoria and ascent, the Feria de Valencia managed to become one of the most important festive events in Valencia, taking on a distinctly popular carac…
