SHOCK-CLOUD INTERACTION AND PARTICLE ACCELERATION IN THE SOUTHWESTERN LIMB OF SN 1006
2014
The supernova remnant SN 1006 is a powerful source of high-energy particles and evolves in a relatively tenuous and uniform environment despite interacting with an atomic cloud in its northwestern limb. The X-ray image of SN 1006 reveals an indentation in the southwestern part of the shock front and the H I maps show an isolated (southwestern) cloud, having the same velocity as the northwestern cloud, whose morphology fits perfectly in the indentation. We performed spatially resolved spectral analysis of a set of small regions in the southwestern nonthermal limb and studied the deep X-ray spectra obtained within the XMM-Newton SN 1006 Large Program. We also analyzed archive H I data, obtain…
Cerebral Dynamics during the Observation of Point-Light Displays Depicting Postural Adjustments
2017
Objective: As highly social creatures, human beings rely part of their skills of identifying, interpreting, and predicting the actions of others on the ability of perceiving biological motion. In the present study, we aim to investigate the electroencephalographic (EEG) cerebral dynamics involved in the coding of postural control and examine whether upright stance would be codified through the activation of the temporal-parietal cortical network classically enrolled in the coding of biological motion. Design: We registered the EEG activity of 12 volunteers while they passively watched point light displays (PLD) depicting quiet stable (QB) and an unstable (UB) postural situations and their r…
Identification of the conceptual, procedural and attitudinaldimensions of scientific activity by trainee teachers
2021
Es importante que los maestros y maestras en formación lleguen a interiorizar las características básicas del trabajo científico, es decir que la actividad científica no solamente se relaciona con leyes, principios, conceptos (dimensión conceptual)... sino que también contempla otras dimensiones esenciales como son la procedimental y la actitudinal. De lo contrario, en su futuro como docentes no las tendrán en cuenta, contribuyendo a visiones reduccionistas y empobrecidas de la actividad científica. Por ello,la presente investigación pretende determinar si los maestros y maestras en formación son capaces de reconocer las tres dimensiones (conceptual, procedimental y actitudinal) de la activ…
Uso de blogs en Ciencias de la Actividad Física y el Deporte
2011
Se describe la experiencia de un proyecto de innovación educativa que consistió en el diseño, desarrollo y evaluación de diversos usos de blogs y que se desarrolló en la Universitat de València, durante el curso académico 2009-10. El análisis refleja la heterogeneidad con la que los diferentes profesores dieron respuesta a los problemas específicos planteados en sus materias. La principal conclusión es que esta flexibilidad en el uso de los blogs supone una singular ventaja para la innovación en educación superior centrada en el aprendizaje de los estudiantes.
Innovative “Green” and Novel Strategies for the Extraction of Bioactive Added Value Compounds from Citrus Wastes—A Review
2017
Citrus is a major processed crop that results in large quantities of wastes and by-products rich in various bioactive compounds such as pectins, water soluble and insoluble antioxidants and essential oils. While some of those wastes are currently valorised by various technologies (yet most are discarded or used for feed), effective, non-toxic and profitable extraction strategies could further significantly promote the valorisation and provide both increased profits and high quality bioactives. The present review will describe and summarize the latest works concerning novel and greener methods for valorisation of citrus by-products. The outcomes and effectiveness of those technologies such a…
Edilizia abusiva a Favara. Analisi dell’insediamento e sviluppo del territorio
2007
Il Piano Regolatore Generale, strumento di fondamentale importanza per lo sviluppo di un centro urbano e del suo territorio, è ancora per diverse città siciliane un obiettivo da raggiungere. I dati provenienti dall'Assessorato Regionale al Territorio e Ambiente (A.R.T.A.) indicano una Sicilia decisamente indietro nella progettazione urbanistica. Nell'isola soltanto il 40,3% dei comuni hanno un piano regolatore vigente. La mancata approvazione degli strumenti urbanistici ha influito negativamente sui processi di urbanizzazione, spesso frammentari e disorganici. Le città si sono sviluppate senza una forma, un modello riconoscibile, alimentando nei cittadini una politica che ha preferito l’edi…
La validación del clima de justicia y de la justicia entre compañeros en un entorno real de trabajo
2016
Abstract In this study we tested the validity of justice climate and peer justice, measured as second-order constructs, in a real work setting. First, we investigated the appropriateness of aggregating first-order facets of justice climate and peer justice to work-unit level of analysis. Second, we examined the construct validity of justice climate and peer justice as two different factor structures. Third, we tested the hierarchical structure of justice climate and peer justice as second-order factors. Finally, we examined the predictive validity of second-order factors justice climate and peer justice within a nomological network composed of reciprocity with the supervisor and reciprocity…
Large clostridial cytotoxins — a family of glycosyltransferases modifying small GTP-binding proteins
1996
Some Clostridium species produce AB x -type protein cytotoxins of high molecular weight. These toxins constitute the group of large clostridial cytotoxins (LCTs), which have homologous protein sequences, exert glycosyltransferase activity and modify GTP-binding proteins of the Ras-superfamily. These characteristics render the LCTs valuable tools for developmental and cell biologists.
