El movimiento de liberación de las mujeres
2023
Este dosier complementa la obra ‘El lugar de las mujeres en la historia’ y ha sido elaborado por el mismo equipo investigador. Con idéntica articulación por capítulos, las propuestas de trabajo, eminentemente prácticas, se han pensado para incitar a la reflexión –tanto en las aulas como fuera de ellas– acerca de los diversos itinerarios de la historia de las mujeres. Fragmentos de obra escrita, imágenes y propuestas de actividades conforman una guía para que quien lea la obra amplíe sus saberes para obtener un conocimiento claro y provechoso, una visión más veraz y completa de nuestra historia, una historia de hombres y mujeres, de lo que fuimos y de lo que somos.

El patrimoni rural com a recurs de desenvolupament local. Els Pelegrins de les Useres
2017
La present tesi doctoral pretén, des de l’àmbit científic del desenvolupament local, aportar el seu granet d’arena a la salvaguarda del pelegrinatge de les Useres. Aquest treball ha volgut ser, tant en els seus objectius com en la forma de dur-lo a terme, una ferramenta més al servei dels valors de la peregrinació de les Useres. Amb freqüència, quan apareixen una llei, un decret, una disposició legislativa, podem arribar a pensar que ja està tot fet; i si no, sovint es cau en la idea que emparant-se a una llei es protegirà el patrimoni. És cert que millor si hi ha una norma que si no hi ha res, perquè al menys així hi ha on agafar-se front a la vulneració de drets. Això no obstant, abans de…
El procés de patrimonialització de les festes de la Mare de Déu de la Salut d'Algemesí (1959-2020)
2022
L’objecte d’estudi d’aquesta investigació és el procés de patrimonialització de les festes de la Mare de Déu de la Salut d’Algemesí –en endavant la Festa–. Des de 1880, la Festa s’estructura en una trilogia de seguicis processionals (la Processó de les Promeses, la Processoneta del Matí i la Processó de Volta General), realitzats els dies 7 i 8 de setembre, cada un amb un itinerari diferent i en el qual participen una sèrie de danses (Muixeranga, Nova Muixeranga, Bastonets, Arquets, Carxofa, Pastorets, Llauradores i Tornejants), la música que les acompanya, realitzada en la majoria de les danses amb dolçaina i tabal, i una sèrie d'elements religiosos, el més important la imatge de la Mare d…
Pickering Emulsion Gels Based on Halloysite Nanotubes and Ionic Biopolymers: Properties and Cleaning Action on Marble Surface
2019
We have fabricated ecocompatible Pickering emulsions based on halloysite nanotubes and ionic biopolymers (chitosan and pectin) from renewable resources. The effect of pectin and chitosan on the Pickering emulsion was investigated by direct visualization of the oil droplets and by the thermodynamic characterization at the interface. Pectin enhances the Pickering emulsion stability, while a phase separation and nonhomogeneous gel was observed in the presence of chitosan. We have demonstrated that the Pickering emulsion in a pectin based gel phase is suitable for wax layer removal from a marble surface. A controlled cleaning is achieved by tuning the contact time between the gel and the marble…
Assessment of the lower limb biomechanics in patients after tibiofibular syndesmosis injury treatment
2021
Purpose: There is no consensus as to the number of bone cortices engaged in tibiofibular syndesmosis treatment. The purpose of our study was to assess the weight distribution on the lower limbs after tricortical or quadricortical syndesmosis fixation and different timing of screw removal. Methods: A total of 55 patients who underwent treatment for acute tibiofibular syndesmosis injury were analyzed in this study. The Zebris pedobarographic platform was used to measure the distribution of body weight on the lower limbs. The study population was stratified by the time to syndesmotic screw removal (8–15 weeks versus 16–22 weeks) and the number of bone cortices involved in fixation (three [tric…
Impurity behaviour in JET-ILW plasmas fuelled with gas and/or with pellets: a comparative study with the transport code COREDIV
2021
Abstract This study deals with the comparison of impurity behaviour in pellet and gas fuelled JET-ITER like wall pulses with the aim of finding the mechanisms leading to the generally observed higher concentration of tungsten in pellet fuelled plasmas. In fact, tungsten is the main high-Z impurity in the JET-ILW plasmas and is responsible for most of the radiative losses in the plasma core. Analysis of the experimental data pertaining to pulses at different plasma currents, different input power and different electron densities is integrated by numerical modelling with the self-consistent fluid transport code COREDIV. Experimentally, and numerically, the ratio between the radiated power in …
Natural Ingredients of Transdermal Drug Delivery Systems as Permeation Enhancers of Active Substances through the Stratum Corneum
2023
In recent years, significant progress has been made in transdermal drug delivery systems, but there is still a search for enhancers that can improve the absorption of active substances through the stratum corneum. Although permeation enhancers have been described in the scientific literature, the use of naturally occurring substances in this role is still of particular interest, because they can offer a high level of safety of use, with a low risk of skin irritation, and high efficiency. In addition, these ingredients are biodegradable, easily available, and widely accepted by consumers due to the growing trust in natural compounds. This article provides information on the role of naturally…
Relationship Between Visual Field Sensitivity and Retinal Nerve Fiber Layer Thickness Measured by Scanning Laser Polarimetry and Optical Coherence To…
2009
Purpose: To evaluate the correlation between automated achromatic perimetry (AAP) and the output of two retinal nerve fiber layer (RNFL) analysers: scanning laser polarimetry (GDx-VCC) and optical coherence tomography (OCT). Methods: Quantitative RNFL measurements with GDx-VCC and Stratus-OCT were obtained in one eye from 52 healthy subjects, 38 ocular hypertensive (OHT) patients and 94 glaucomatous patients. All patients underwent a complete examination, including AAP using the Swedish interactive threshold algorithm (SITA). The relationship between RNFL measurements and SITA visual field global indices were assessed by means of the following methods: analysis of variance, bivariate Pearso…
Neutron Radiography Visualization of Solid Particles in Stirring Liquid Metal
2015
Abstract This paper presents the analysis of the first dynamic neutron radiography experiment that visualized motion of solid particles in liquid metal, which was stirred by a system of four counter-rotating magnets. The paper also contains the quantitative results derived from neutron images: the distribution of particle concentration, number of admixed particles and velocities as functions of the magnet rotation speed.
