BUSCADOR RECOLECTA

A hierarchical hybrid coating (HHC) comprising a ceramic oxide layer and two biodegradable polymeric (polycaprolactone, PCL) layers has been developed on Mg3Zn0.4Ca cast alloy in order to provide a controlled degradation rate and functionality by creating a favorable porous surface topography for cell adhesion. The inner, ceramic layer formed by plasma electrolytic oxidation (PEO) has been enriched in bioactive elements (Ca, P, Si). The intermediate PCL layer sealed the defect in the PEO layer and the outer microporous PCL layer loaded with the appropriate active molecule, thus providing drug-eluting capacity. Morphological, chemical, and biological characterizations of the manufactured coatings loaded with ciprofloxacin (CIP) and paracetamol (PAR) have been carried out. In vitro assays with cell lines relevant for cardiovascular implants and bone prosthesis (endothelial cells and premyoblasts) showed that the drug-loaded coating allows for cell proliferation and viability. The study of CIP and PAR cytotoxicity and release rate indicated that the porous PCL layer does not release concentrations detrimental to the cells. However, complete system assays revealed that corrosion behavior and increase of the pH negatively affects cell viability. H2 evolution during corrosion of Mg alloy substrate generates blisters in PCL layer that accelerate the corrosion locally in crevice microenvironment. A detailed mechanism of the system degradation is disclosed. The accelerated degradation of the developed system may present interest for its further adaptation to new cancer therapy strategies.

Electron microprobe and micro-Raman analysis of two samples collected in the Fe-Mn supergene enrichment zone of the Serra da Mina vein-hosted deposit, Iberian Pyrite Belt, SW Portugal. Data collected in the framework of a research project focusing on the paragenetic sequence of Mn oxides and the corresponding associated changes in physical-chemical conditions.

Esta base de datos está configurada por archivos de imagen, archivos que combinan imagen y texto y datos médicos. Las imágenes corresponden a tres bodegones que sirvieron de modelo y a la obra pictórica, con temple acrílico sobre lienzo, de cuatro sujetos con discromatopsia, estudiantes del Grado en Bellas Artes de la Universidad Complutense de Madrid. Se muestra la codificación de los tonos empleados por las personas participantes en el estudio. Hay, también, notas procesuales, que incluyen reflexiones de cada participante sobre la ejecución pictórica e imágenes del resultado conseguido en cada sesión. Finalmente, se incluyen los resultados del test CAD de visión cromática para cada sujeto.

The aim of the Teacher Learning for European Literacy Education (TeL4ELE) project was to support literacy educators in five European countries to become experts in genre based literacy pedagogy and in turn support teachers to improve learning outcomes for all students especially those who are educationally disadvantaged. Based on the external evaluation of the project1 this aim was fulfilled. Survey and interview data showed high levels of engagement with the pedagogy on the part of both educators and classroom teachers. Ninety seven per cent2 stated that, in their view, the pedagogy offered a completely different approach to reading and writing compared to those that are generally used in school. Moreover almost all teachers perceived it had had an impact on their students’ understanding of how language operates in different texts to make meaning and on their students’ reading and writing. Ninety two per cent wished to continue with the approach citing the following reasons as motivation: improvement in student learning, empowering nature of pedagogy, enjoyed working with the approach. Most significantly students’ assessment scores based on their pre and post reading and writing scores showed that all students (drawn from the 97 participating classes) had improved by an average of 14.3 % on their writing and 9% on their reading (in almost half of all cases in less than 5 weeks).
