We would like to thank the study participants and the clinical and research staff at the Queen Elizabeth National Spinal Injury Unit, as without them this study would not have been possible. We are grateful for the funding received from Glasgow Research Partnership in Engineering for the employment of SC during data collection for this study. We would like to thank the Royal Society of Edinburgh's Scottish Crucible scheme for providing the opportunity for this collaboration to occur. We are also indebted to Maria Dumitrascuta for her time and effort in producing inter-repeatability results for the shape models.

El objetivo del artículo es analizar algunos aspectos de los orígenes de la “política cultural” estadounidense en Argentina. La atención se concentrará en el pasaje desde las declaraciones del presidente Hoover, que contribuyeron a favorecer un clima útil y propicio a la intensificación de los intercambios, a los primeros pasos concretos realizados en el periodo de la presidencia de Roosevelt. Se tratará, en particular, de individualizar las características de la cooperación establecida entre organismos estadounidenses y argentinos para favorecer la proyección cultural estadounidense en el país y el intercambio cultural entre Estados Unidos y Argentina, donde se iba intensificando la difusión de un sentimiento anti-imperialista, y que era entonces objetivo de formas de propaganda particularmente agresivas por parte de los regímenes totalitarios.

In the casting of reactive metals, such as titanium alloys, contamination can be prevented if there is no contact between the hot liquid metal and solid crucible. This can be achieved by containing the liquid metal by means of high frequency AC magnetic field. A water cooled current-carrying coil, surrounding the metal can then provide the required Lorentz forces, and at the same time the current induced in the metal can provide the heating required to melt it. This ‘attractive’ processing solution has however many problems, the most serious being that of the control and containment of the liquid metal envelope, which requires a balance of the gravity and induced inertia forces on the one side, and the containing Lorentz and surface tension forces on the other. To model this process requires a fully coupled dyna ic solution of the flow fields, magnetic field and heat transfer/melding process to account for. A simplified solution has been published previously providing quasi-static solutions only, by taking the irrotational ‘magnetic pressure’ term of the Lorentz force into account. The authors remedy this deficiency by modelling the full problem using CFD techniques. The salient features of these techniques are included in this paper, as space allows.

This was a peer-reviewed event that took place at the DiGRA-FDG conference in August 2016. While it has a paper component (the attached proposal), the output was a demonstration of games rather than a conference paper. As such, this entry should be considered an Event or Exhibition.

Abordamos hermenêuticamente a descentralização e a territorialização educativa em Portugal, numa tríade de relações: ‘escola-comunidade educativa’, parceria socioeducativa e política educativa local. A intervenção do poder local na educação processa-se numa perspetiva instrumental virada para o desenvolvimento e coesão social. As autarquias são os parceiros responsáveis pela educação e os professores valorizam a relação escola-comunidade educativa, principalmente na promoção da qualidade. A relação ’escola-poder local’ efetua-se numa interação participativa dos laços redutores e promotores da administração e gestão escolar, com lógicas de ação e racionalização das parcerias.
