A broader model for C 4 photosynthesis evolution in plants inferred from the goosefoot family (Chenopodiaceae s.s.)
2012
C 4 photosynthesis is a fascinating example of parallel evolution of a complex trait involving multiple genetic, biochemical and anatomical changes. It is seen as an adaptation to deleteriously high levels of photorespiration. The current scenario for C 4 evolution inferred from grasses is that it originated subsequent to the Oligocene decline in CO 2 levels, is promoted in open habitats, acts as a pre-adaptation to drought resistance, and, once gained, is not subsequently lost. We test the generality of these hypotheses using a dated phylogeny of Amaranthaceae s.l. (including Chenopodiaceae), which includes the largest number of C 4 lineages in eudicots. The oldest chenopod C 4 lineage da…

Biodiversity, evolution and adaptation of fungi in exstreme environments
2013
Fungi play irreplaceable roles for ecosystem functioning. They may adopt different life styles, for example saprotrophs, symbionts or parasites: some species are cosmopolitan with a wide distribution and others, thanks to they ecological plasticity, may adapt to harsh environments precluded to most of life forms. In stressing conditions, their role is even more crucial for the recycling of organic matter or favouring nutrients uptake. When the conditions become really extreme and competion is low, fungi focus on extremotollerance and evolve peculiar competences to exploit natural or xenobiotic resources in the particular constraints imposed by the environment. This paper focuses on three di…
Technical Note: Prediction Models of Airborne Sound Insulation of Multilayer Materials with Viscoelastic Thin Sheets
2008
The growing introduction of new insulation materials in building acoustics has caused an increase of the importance of the prediction tools. Appropriate simulations allow strictly necessary laboratory measurements to be identified. In this way, costs are reduced. The demands of new legislation has resulted in the appearance of various software designed to facilitate prediction. The prediction models are based on different hypotheses: adaptation of impedances, spatial behaviour of spectral components, statistical energy distribution, the Finite Element Method (FEM), etc. Each of these models and methods offer advantages and contain limitations. In this paper, different models for prediction…
La adaptación cultural en estudiantes extranjeros
2015
En este trabajo, se desarrolla el concepto de adaptación cultural, particularmente se aborda la adaptación de los estudiantes extranjeros. Se plantean diferentes modelos explicativos y se comentan diferentes niveles de adaptación. Se trabaja con conceptos como aculturación y estrés por aculturación. Por último, se comentan algunas de las investigaciones que abordaron los factores que favorecen la integración del estudiante extranjero.
Psychological State after an Acute Coronary Syndrome: Impact of Physical Limitations
2021
The aim of this study was to investigate how physical limitations after ACS influence patients’ quality of life and health perception. This was a longitudinal clinical study. We recruited 146 patients diagnosed with ACS. The patients performed a stress test (Bruce’s protocol) for the evaluation of physical limitations and were classified according to the test result: without physical limitations (more than 10 METS), with some physical limitations (7 to 9 METS), and with high physical limitations (less than 6 METS). Significant differences were found between the three groups immediately after the diagnosis of ACS and after a period of three months, regarding health perception, anxiety, depre…
El «Llibre de les Bèsties» (1287-1289) de Ramon Llull: anàlisi d'adaptacions infantils i juvenils
2020
En aquest article presentem una anàlisi de les sis adaptacions que del Llibre de les Bèsties (1287- 1289) es van publicar per al públic infantil i juvenil amb motiu de l’Any Llull (2015-2016). Després de presentar la figura de Ramon Llull com a escriptor de referència en l’època medieval i de situar Llibre de les Bèsties dins de la producció literària de Llull, analitzem els paratextos extratextuals i textuals de les sis adaptacions aquí estudiades. La presentació i l’anàlisi d’aquests paratextos ens permet determinar, d’una banda, a quin tipus de nivell lector va adreçada cada adaptació i quin treball didàctic en pot resultar; i, d’altra banda, com el missatge que Llull transmet en aquesta…
Historia de vida de un alumno con distrofia muscular
2016
La distrofia muscular es una enfermedad que avanza muy rápida entre los 7 y los 12 años y poco común. Sus síntomas son la falta de movilidad en las extremidades y complicaciones a la hora de respirar. En este trabajo, a partir de la historia de vida de un adolescente con distrofia muscular de Duchenne, se pretende analizar cuáles son las dificultades que sufren los niños que la padecen en la escuela tanto a nivel material como a nivel de implicación y trabajo de los educadores. Esto ligado a una propuesta de con actividades que podrían realizar los maestros y maestras dentro de su aula con un alumnado con dicha enfermedad.
Distance Learning for Social Distancing through LMOOCs: From Local to Massive and Back
2022
This chapter discusses the first step of the adaptation of a Language Massive Open Online Course (LMOOC) offered on EdX4 to be used in higher education contexts as a result of social distancing measures imposed by the COVID19 outbreak and the sudden pivot to online learning. The LMOOC contents recently underwent a process of redesign and conversion from small-scale to massive and now the opposite move is necessary: the LMOOC is to go local by becoming embedded in English classes in higher education contexts. Participants’ feedback was analyzed and compared with the criteria from a MOOC analysis matrix in terms of content variety, quality of contents and instructors, linguistic level and ade…
Posibles causas del fracaso escolar y el retorno al sistema educativo.
2011
En el presente estudio de investigación educativa, los principales objetivos perseguidos son encontrar las posibles causas del fracaso escolar y el retorno al sistema educativo, mediante una muestra de 100 alumnos/as del C.F.P.A Germà Colón de Castelló de la Plana. Se ha utilizado una encuesta, que pretende reflejar las posibles influencias que han llevado al alumnado al fracaso escolar, así como el porqué de su retorno. Se han obtenido una serie de resultados, de los cuales destaca la notable influencia del profesorado, que lleva a una alta insatisfacción de los sujetos en cuanto a la insuficiente atención individualizada y a las clases no motivadoras ni participativas. Además se ha encont…
