¿Cuáles son los referentes deportivos femeninos en los libros de texto de Educación Física?
2018
La representación de las mujeres deportistas en los libros de texto españoles es un campo de estudio poco analizado en comparación con el análisis de la presencia femenina en los medios desde una perspectiva generalista. La finalidad de este estudio es averiguar cuáles son los referentes deportivos femeninos que aparecen en los libros de texto de Educación Física (EF) en Educación Primaria (EP), a la vez que reflexionar sobre su ausencia en el imaginario social, de manera que niñas y adolescentes carecen de modelos referentes a los cuales imitar. Se realiza un estudio cuantitativo que confirma su infrarrepresentación con respecto a los deportistas masculinos, en el máximo evento deportivo c…

Plankton Ecology and Diversity
2010
In this chapter we describe plankton responses induced by fluctuating hydrology and eutrophication process in the semi-arid TDNP wetland. We have followed the planktonic community since 1992, at seasonal and interannual scales, covering as well the spatial heterogeneity of the wetland. The studied planktonic components were bacterioplankton, autotrophic picoplankton, nano and microphytoplankton and zooplankton, including ciliates. Plankton has been studied in terms of species composition (diversity), functional groups, spatial heterogeneity, population dynamics. The present data from this wetland allow us to determine which factors (resources and conditions) are relevant for each group and …
Axial Flux Permanent Magnet Synchronous Generators for Pico Hydropower Application: A Parametrical Study
2022
A pico hydropower plant is an energy harvesting system that allows energy production using the power of the water flowing in small watercourses, and in water distribution network. Axial Flow Flux Permanent Magnet Synchronous Generator (AFPMSG) are particularly suitable for this application, being efficient machines that achieve high power with small dimensions. This paper presents a parametrical study of several configurations and topologies of three-phase and single-phase AFPMSG, for pico hydropower application, to assess the most suitable dimensional characteristics for the most energy production using a safe voltage of 25 V. The AFPMSGs here considered has a simple single stator and roto…
The fumarolic CO2 output from Pico do Fogo volcano (Cape Verde)
2020
The Pico do Fogo volcano, in the Cape Verde Archipelago off the western coasts of Africa, has been the most active volcano in the Macaronesia region in the Central Atlantic, with at least 27 eruptions during the last 500 years. Between eruptions fumarolic activity has been persisting in its summit crater, but limited information exists for the chemistry and output of these gas emissions. Here, we use the results acquired during a field survey in February 2019 to quantify the quiescent summit fumaroles' volatile output for the first time. By combining measurements of the fumarole compositions (using both a portable Multi-GAS and direct sampling of the hottest fumarole) and of the SO2 flux (u…
Teschoviruses and sapeloviruses in faecal samples from wild boar in Spain
2013
Teschovirus and Sapelovirus are two genera of the Picornaviridae family, comprising highly variable and heterogeneous enteric viruses, commonly found in faecal samples from domestic pigs. Although both of them are also known to infect wild boar, studies on their presence in these wild suids are scarce. The present study aimed at determining the presence of porcine teschovirus (PTV) and sapelovirus (PSV) in free-living wild boar populations, as well as to study their relationships with similar viruses present in pigs. Fresh faecal samples (n = 63) from wild boar were collected in Doñana Biological Reserve (SW Spain) during 2007 and 2011, and analysed using multiplex RT-PCR for the simultaneo…
Fusulines of the Hoyo Oscuro section, Ándara massif of Picos de Europa (Cantabrian Zone, N Spain). New constraints about the onset of the Variscan de…
2020
The Hoyo Oscuro section (Andara Massif, southeastern part of Picos de Europa) is a comparatively small exposure of Pennsylvanian syntectonic deposits that shown angular unconformity on the fairly extensive pre-tectonic carbonate platform strata of Pennsylvanian age accumulated in the distalmost realms of the Variscan foreland basin of the Cantabrian Zone. Fusuline-bearing strata from this section yielded species belonging to the genera P seudostaffella, Ozawainella, Fusulinella, Protriticites, Pseudotriticites, Fusulina and Quasifusulinoides ; one of these forms, Protriticites schulzei Villa, is described as a new species from the Cantabrian Mountains. Fusuline assemblages allow us to corre…
Dall'epico al grottesco. "La Guerra de' Mostri" di Antonfrancesco Grazzini
2019
Il poema in ottave "La Guerra de’ Mostri", composto da Antonfrancesco Grazzini nel 1547 – all’indomani della sua cacciata dall’Accademia Fiorentina – attesta l’evoluzione in chiave eroicomica del genere letterario e insieme testimonia, attraverso il filtro dell’allegoria, il mutamento della funzione intellettuale attuatosi a metà Cinquecento, costituendo un affascinante esemplare della dialettica rinascimentale fra dimensione comica e dimensione epica.
El síndrome de Kallmann. Correlación fenotipo-genotípica.
2015
El Síndrome de Kallmann (SK) es una enfermedad genética del desarrollo, que asocia un hipogonadismo hipogonadotrópico (HH) congénito con pérdida total (anosmia) o parcial (hiposmia) del olfato. La alteración olfativa es secundaria a la aplasia o hipoplasia de las estructuras olfatorias (bulbos, tractos y surcos cerebrales olfatorios). El HH se debe a la deficiencia en la hormona liberadora de gonadotropinas hipotalámica (GnRH) como resultado del fallo en la migración de las neuronas productoras de esta hormona, por las vías olfatorias, desde la placoda olfatoria hasta el hipotálamo durante el desarrollo embrionario. La prevalencia del déficit de GnRH congénito se estima que es del orden de …
Droplet digital PCR as a tool for investigating dynamics of cryptic symbionts
2021
Abstract Interactions among symbiotic organisms and their hosts are major drivers of ecological and evolutionary processes. Monitoring the infection patterns among natural populations and identifying factors affecting these interactions are critical for understanding symbiont–host relationships. However, many of these interactions remain understudied since the knowledge about the symbiont species is lacking, which hinders the development of appropriate tools. In this study, we developed a digital droplet PCR (ddPCR) assay based on apicomplexan COX1 gene to detect an undescribed agamococcidian symbiont. We show that the method gives precise and reproducible results and enables detecting cryp…
