importancia curricular de la Educación para la Ciudadanía en las escuelas de la Unión Europea
2022
Actualmente la sociedad se enfrenta a grandes desafíos a los que debe responder. Las Naciones Unidas aprobaron en 2015 la Agenda 2030 junto con los Objetivos de Desarrollo Sostenible con el fin de crear una ciudadanía capaz de dar respuesta a las necesidades y retos de la sociedad. Desde 1992 Europa sintió la necesidad crear una ciudadanía supranacional compuesta por todos los ciudadanos que forman la Unión Europea. La Educación para la Ciudadanía cumple con esta función y su implementación en los sistemas educativos de los países es muy diversa, dando como resultado diferentes ciudadanos.
El arquitecto Rafael Guastavino (1842-1908): obra en cuatro actos
2018
[EN] This text presents extensive new information on the figure of architect Rafael Guastavino Moreno (1842-1908), those around him, and his personal and family relationships with architecture. It also examines other artistic fields and trades such as music, carpentry and winemaking, all of which influenced and obtained feedback for Guastavino¿s architecture within the historical, political and economic situation of the three places where he lived in Spain: Valencia, Barcelona and Almudévar (Huesca), before emigrating to the United States of America, where his successful professional career as an architect is widely recognized in the literature
An Ovalbumin Peptide-Specific Cytotoxic T Cell Clone with Antigen Self-Presentation Capacity Uses Two Distinct Mechanisms to Kill Target Cells
1993
Abstract Cloned 10BK.1 T cells with specificity for the ovalbumin peptide OVA257-264 are representative of a novel cell type within the CD8 + subset of T cells. In the presence and in the absence of added antigen presenting cells these T cells react toward antigen (Ag) by proliferation and lymphokine production. These data suggest self-presentation of the Ag by 10BK.1 cells. Here we present evidence that 10BK.1 cells exhibit cytotoxic activity that involves two different cytotoxic effector mechanisms. (i) One mechanism is fast killing activity, apparent within 4 hr. Constitutive mouse T cell-specific proteinase-1 (MTSP-1) activity, constitutive expression of MTSP-1 RNA, increased by Ag chal…
La oscura memoria: cine negro y brechas fantásticas en Enterrar a los muertos (2005) y Las serpientes ciegas (2008) [Una contraposición]
2021
La literatura en torno a la memoria es uno de los puntales de la narrativa hispánica reciente. Lo que este artículo pretende es adentrarse en una de sus áreas más inexploradas (las purgas estalinistas en España durante la Guerra Civil) a través del análisis y la confrontación de dos obras tan reconocidas como heterodoxas: la novela Enterrar a los muertos, de Ignacio Martínez de Pisón, y el cómic Las serpientes ciegas, de Felipe Hernández Cava y Bartolomé Seguí. La pasarela que comunica ambos textos es la estética de cine negro que ambienta el cómic y que –como intentaremos demostrar– modula la tensión de la novela. El final del camino lo marca el empleo de lo fantástico por parte de Cava y …
Functional Inactivation of pRB Results in Aneuploid Mammalian Cells After Release From a Mitotic Block
2002
AbstractThe widespread chromosome instability observed in tumors and in early stage carcinomas suggests that aneuploidy could be a prerequisite for cellular transformation and tumor initiation. Defects in tumor suppressers and genes that are part of mitotic checkpoints are likely candidates for the aneuploid phenotype. By using flow cytometric, cytogenetic, immunocytochemistry techniques we investigated whether pRB deficiency could drive perpetual aneuploidy in normal human and mouse fibroblasts after mitotic checkpoint challenge by microtubule-destabilizing drugs. Both mouse and human pRB-deficient primary fibroblasts resulted, upon release from a mitotic block, in proliferating aneuploid …
Genomic instability induced by α-pinene in Chinese hamster cell line.
2012
Here, we report the effects of exposure of mammalian cells to α-pinene, a bicyclic monoterpene used in insecticides, solvents and perfumes. Morphological analysis, performed in V79-Cl3 cells exposed for 1 h to increasing concentrations (25 up to 50 μM) of α-pinene, indicated a statistically significant increase in micronucleated and multinucleated cell frequencies; apoptotic cells were seen at 40 and 50 μM. This monoterpene caused genomic instability by interfering with mitotic process; in fact, 50% of cells (versus 19% of control cells) showed irregular mitosis with multipolar or incorrectly localised spindles. Cytogenetic analysis demonstrated high-frequency hypodiploid metaphases as well…
Quantification of Listeria monocytogenes in salads by real time quantitative PCR
2005
Abstract A real time quantitative PCR (RTQ-PCR) was carried out purifying DNA extracts of Listeria monocytogenes using a High Pure Listeria Sample Preparation Kit and quantifying in a LightCycler system with hybridisation probes. A standard curve was constructed with serial dilutions. A range linear relationship, from 10 to 10 5 L. monocytogenes colony forming units (CFU), was observed between threshold cycle ( C t ) and logarithmic concentration of the serial dilutions. The assay was linear in a range from 10 to 10 5 L. monocytogenes CFU and the coefficient of determination ( r 2 ) was > 0.98. RTQ-PCR presented an efficiency of > 85%. The accuracy of the PCR-based assay, expressed as % bia…
Coordinated Interpersonal Behaviour in Collective Dance Improvisation: The Aesthetics of Kinaesthetic Togetherness
2018
International audience; Collective dance improvisation (e.g., traditional and social dancing, contact improvisation) is a participatory, relational and embodied art form which eschews standard concepts in aesthetics. We present our ongoing research into the mechanisms underlying the lived experience of "togetherness" associated with such practices. Togetherness in collective dance improvisation is kinaesthetic (based on movement and its perception), and so can be simultaneously addressed from the perspective of the performers and the spectators, and be measured. We utilise these multiple levels of description: the first-person, phenomenological level of personal experiences, the third-perso…
Capturing and Indexing Rehearsals: The Design and Usage of a Digital Archive of Performing Arts
2015
International audience; Preserving the cultural heritage of the performing arts raises difficult and sensitive issues, as each performance is unique by nature and the juxtaposition between the performers and the audience cannot be easily recorded. In this paper, we report on an experimental research project to preserve another aspect of the performing arts—the history of their rehearsals. We have specifically designed non-intrusive video recording and on-site documentation techniques to make this process transparent to the creative crew, and have developed a complete workflow to publish the recorded video data and their corresponding meta-data online as Open Data using state-of-the-art audi…
Experimental Study Regarding PA and PE Sheets on Single Point Incremental Forming Process
2021
The present paper aims to present an experimental study on the behaviour of PA and PE sheets during the single point incremental forming. Due to the fact that the purpose of this research is to study the behaviour of PA and PE sheets during the single point incremental process both in terms of process forces and in terms of major and minor strain and thickness reduction, a Kuka Kr210 robot was chosen as an alternative to using a universal milling machine. The specimens were made of 3 mm PA and PE sheets. The size of the sheets was 250 mm x 250 mm. The forces measured on the three directions of the coordinate axes were compared. To measure the major strain, minor strain and thickness reducti…
