High-grade metamorphism and partial melting of basic and intermediate rocks
2016
Rocks of basic and intermediate bulk composition occur in orogenic terranes from all geological time periods and are thought to represent significant petrological components of the middle and lower continental crust. However, the former lack of appropriate thermodynamic models for silicate melt, amphibole and clinopyroxene that can be applied to such lithologies at high temperature has inhibited effective phase equilibrium modelling of their petrological evolution during amphibolite- and granulite facies metamorphism. In this work, we present phase diagrams calculated in the Na2O–CaO–K2O–FeO–MgO–Al2O3–SiO2–H2O–TiO2–O2 (NCKFMASHTO) compositional system for a range of natural basic and interm…
High-grade metamorphism and partial melting in Archean composite grey gneiss complexes
2016
Much of the exposed Archaean crust is composed of composite gneiss which includes a large proportion of intermediate to tonalitic material. These gneiss terrains were typically metamorphosed to amphibolite to granulite facies conditions, with evidence for substantial partial melting at higher grade. Recently published activity–composition (a-x) models for partial melting of metabasic to intermediate compositions allows calculation of the stable metamorphic minerals, melt production and melt composition in such rocks for the first time. Calculated P–T pseudosections are presented for six bulk rock compositions taken from the literature, comprising two metabasic compositions, two intermediate…
An Additive Model to Predict the Rheological and Mechanical Properties of Polypropylene Blends Made by Virgin and Reprocessed Components
2021
In this work, an additive model for the prediction of the rheological and mechanical properties of monopolymer blends made by virgin and reprocessed components is proposed. A polypropylene sample has been reprocessed more times in an extruder and monopolymer blends have been prepared by simulating an industrial process. The scraps are exposed to regrinding and are melt reprocessed before mixing with the virgin polymer. The reprocessed polymer is, then, subjected to some thermomechanical degradation. Rheological and mechanical experimental data have been compared with the theoretical predictions. The results obtained showed that the values of this simple additive model are a very good fit fo…
Visualization of Simulated Arrhythmias due to Gap Junctions
2018
New computational models are able to simulate details of cardiac cell networks. Their results allow a better understanding of the functionality of the heart and suggest possible actions to reduce non-fatal premature beats that can give rise to serious diseases. We developed a user-friendly interface to organize Neuron simulations and to present in real-time a three-dimensional representation of the electrical activity due to the gap junctions which interconnect the cells inside cardiac tissues. All physiological parameters were set according to real experimental observations and compared against different types of arrhythmias, retrieved from the Physionet Data Base.

The effectiveness of the GoKoan e-learning platform in improving university students’ academic performance
2021
Abstract The GoKoan e-learning platform supports face-to-face training in an educational community. Its aim is to optimise the way and the time of study in order to improve academic performance. To evaluate the GoKoan platform’s effectiveness as a tool for improving academic performance, an experimental study was carried out using a sample of 171 university students enrolled in the psychology degree programme who were randomly assigned to the two different conditions (the experimental group: traditional learning + e-learning with the GoKoan platform; and the control group: traditional learning without e-learning). The findings showed that using GoKoan had a positive impact on the students’ …
Beyond the “student” position: Pursuing agency by drawing on learners’ life-worlds on an EAP course
2018
AbstractIn today’s world, individuals should be able to maintain their expertise amidst constant changes. Thus, this type of agency should be supported in higher education. One approach for a teacher-researcher to examine supporting agency and how it manifests itself in higher education courses is through the learning design. In this article, learning design is defined as the planned course path and the way in which that path is enacted in the course in a real-life setting. Thus, the learning design of a blended EAP course is examined, with a focus on the course assignments in two different groups in two consecutive years. Different types of agency were assumed through the tasks and those t…
Training the modern translator – the acquisition of digital competencies through blended learning
2019
This paper presents the ERASMUS+ DigiLing project, which aims to teach and improve linguists’ and translators’ skills and knowledge of digitalisation to prepare them for today’s job market. Against this background, it discusses the development of digital competencies and distinguishes them from traditional domain-specific and general competencies. For the purpose of competence acquisition, six online courses have been created which all revolve around the field of ‘digital linguistics’, including localization in the digital age and post-editing machine translation. We provide an overview of the project, the course contents and the didactic methodology. In addition, we discuss which competenc…
From face-to-face to blended learning using ICT
2016
This study examines the development of the education model created in connection with the Master Studies in Mathematical Information Technology. The model has developed from the first stage, where there was only face-to-face teaching supported with Learning Management System, to a stage where studying is possible also fully in online and students may choose themselves how much to take advantage of technology in their studies. The examination of the development of the education model is made from the viewpoints of accessibility, increased role of technology and interaction. In earlier studies, the education model has been evaluated for example from the viewpoints of changes in the participat…
Las familias reconstituidas. Una realidad en continuo crecimiento
2020
Cada vez más parejas que han contraído matrimonio o formalizado su unión se disuelven y vuelven a formar otras familias, las llamadas familias reconstituidas. En ellas se involucran adultos y menores, por lo que necesitan una identidad propia que determine los derechos y obligaciones de cada uno. Aunque nada se ha previsto en el Código civil español, no acontece igual en otros Derechos, como en algunos de los llamados Derechos forales y en los ordenamientos jurídicos de otros países. Partiendo de ello, en este artículo vamos a realizar algunas consideraciones en torno a lo que podría ser su régimen jurídico. More and more couples who have married or formalized their union are dissolving and…
