El pacifismo-antimilitarismo en España desde el siglo XIX hasta la Guerra Civil: los «efectos desplazamiento»

2019

La historia del antimilitarismo en el Estado español es, en gran medida, desconocida. El presente trabajo pretende subsanar parcialmente esta carencia mediante la compilación de la literatura y las fuentes existentes sobre la materia, parciales o basadas en períodos específicos, exponiendo estas resistencias desde el pacifismo inicial del siglo XIX hasta el final de la Guerra Civil. Esta labor se realiza desde la confluencia entre la historia y la sociología, insertando estas movilizaciones en los conflictos y los movimientos internacionales, mostrando cómo se influyen mutuamente, así como la convergencia entre el feminismo y el antimilitarismo. Asimismo, se constata cómo la defensa de la p…

Maria Mulet, escriptora i docent (1911-1982)

2020

Resum: Els estudis sobre les contribucions de les escriptores valencians de la postguerrasón més aviat escassos, però a poc a poc s’avança en aquesta matèria. En el present treballtractem de poesia escrita per dones al llarg de la postguerra i, concretament, començareml’estudi de l’obra de Maria Mulet, nascuda el 1911 i que va ser una de les dones silenciadesque van experimentar un canvi social després de la guerra i que en van patir les conseqüències.Mestra i escriptora que sabia molt bé aprofitar tots els recursos que havia de subministrarper a escriure i treballar, va escriure en valencià i en castellà, a més de ser creadora de lecturesper a utilitzar-les a l’aula, en un moment en què l…

Measuring agglomeration by spatial effects: a proposal

2015

In this paper we examine the influence of spatial dependence on the estimation of the effect of standard measures of agglomeration on local growth. The hypothesis is that the forces of agglomeration do not use up their effects inside a single local area but extend to wider geographic areas, particularly on the adjacent territories. To account for these spatial effects, we propose a modification of the traditional agglomeration index, suggested by Maurel and Sedillot (1999), including both agglomeration of economic activity within an area and neighbour effects, that is, the effect of agglomeration that comes from neighbouring areas. In the empirical exercise we compute the a-spatial and the …

Proximal-sensing-powered modelling of energy-water fluxes in a vineyard: A spatial resolution analysis

2021

Spatial resolution is a key parameter in energy–water surface flux modelling. In this research, scale effects are analyzed on fluxes modelled with the FEST-EWB model, by upscaling both its inputs and outputs separately. The main questions are: (a) if high-resolution remote sensing images are necessary to accurately model a heterogeneous area; and (b) whether and to what extent low-resolution modelling provides worse/better results than the upscaled results of high-resolution modelling. The study area is an experimental vineyard field where proximal sensing images were obtained by an airborne platform and verification fluxes were measured via a flux tower. Modelled fluxes are in line with th…

Changes in Onset of Vegetation Growth on Svalbard, 2000–2020

2022

The global temperature is increasing, and this is affecting the vegetation phenology in many parts of the world. The most prominent changes occur at northern latitudes such as our study area, which is Svalbard, located between 76°30′N and 80°50′N. A cloud-free time series of MODIS-NDVI data was processed. The dataset was interpolated to daily data during the 2000–2020 period with a 231.65 m pixel resolution. The onset of vegetation growth was mapped with a NDVI threshold method which corresponds well with a recent Sentinel-2 NDVI-based mapping of the onset of vegetation growth, which was in turn validated by a network of in-situ phenological data from time lapse cameras. The results show th…

FUNCTIONALIZED HALLOYSITE NANOTUBES FOR ENHANCED REMOVAL OF Hg2+ IONS FROM AQUEOUS SOLUTIONS

2021

AbstractWater is essential for humans, animals, and plants; pollutants, usually derived from anthropogenic activities, can have a serious effect on its quality. Heavy metals are significant pollutants and are often highly toxic to living organisms, even at very low concentrations. Among the numerous removal techniques proposed, adsorption onto suitable adsorbent materials is considered to be one of the most promising. The objective of the current study was to determine the effectiveness of halloysite nanotubes (HNT) functionalized with organic amino or thiol groups as adsorbent materials to decontaminate polluted waters, using the removal of Hg2+ ions, one of the most dangerous heavy metals…

Model, software and database for line-mixing effects in the nu3 and nu4 bands of CH4 and tests using laboratory and planetary measurements - II : H2 …

2006

International audience; The absorption shapes of the nu(2), nu(3) and nu(4) infrared bands of CH4 perturbed by H-2 in large ranges of pressure and temperature have been measured in the laboratory. In order to model these spectra, the theoretical approach accounting for line-mixing effects proposed for CH4-N-2 and CH4-air and successfully tested in the companion paper (1), is used. As before, state-to-state rotational rates are used together with some empirical parameters that are deduced from a fit of a single room temperature spectrum of the nu(3) band at about 50 atm. The comparisons between measured and calculated spectra in the nu(3) and nu(4) regions under a vast variety of conditions …

INTEGRAL and RXTE observations of accreting millisecond pulsar IGR J00291+5934 in outburst

2005

Simultaneous observations of the accretion-powered millisecond pulsar IGR J00291+5934 by International Gamma-Ray Astrophysics Laboratory and Rossi X-ray Timing Explorer during the 2004 December outburst are analysed. The average spectrum is well described by thermal Comptonization with an electron temperature of 50 keV and Thomson optical depth tau_T ~ 1 in a slab geometry. The spectral shape is almost constant during the outburst. We detect a spin-up of the pulsar with nudot=8.4x10E-13 Hz/s. The ISGRI data reveal the pulsation of X-rays at a period of 1.67 milliseconds up to ~150 keV. The pulsed fraction is shown to increase from 6 per cent at 6 keV to 12--20 per cent at 100 keV. This is n…
