Tidal Energy ”Round Robin” Tests Comparisons between towing tank and circulating tank results

One key step of the industrial development of a tidal energy device is the testing of scale prototype devices within a controlled laboratory environment. At present, there is no available experimental protocol which addresses in a quantitative manner the differences which can be expected between results obtained from the different types of facilities currently employed for this type of testing. As a consequence, where differences between results are found it has been difficult to confirm the extent to which these differences relate to the device performance or to the test facility type. In the present study, a comparative ”Round Robin” testing programme has been conducted as part of the EC FP VII MaRINET program in order to evaluate the impact of different experimental facilities on the test results. The aim of the trials was to test the same model tidal turbine in four different test facilities to explore the sensitivity of the results to the choice of facility. The facilities comprised two towing tanks, of very different size, and two circulating water channels. Performance assessments in terms of torque, drag and inflow speed showed very similar results in all facilities. However, expected differences between the different tank types (circulating and towing) were observed in the fluctuations of torque and drag measurements. The main facility parameters which can influence the behaviour of the turbine were identified; in particular the effect of blockage was shown to be significant in cases yielding for high thrust coefficients, even at relatively small blockage ratios.

Robin Hood: de leyenda a mito cultural

[es] A lo largo de la historia, los villanos, ya sean reales o imaginarios, han tenido funciones útiles para la sociedad y a menudo han actuado como «válvulas de seguridad» para aliviar las presiones sociales. Esta es probablemente la razón por la que muchos «villanos» han sido definidos como «bandidos sociales», término utilizado originalmente por Eric Hobsbawm para referirse a un forajido quizás mejor ejemplificado por el personaje de Robin Hood en la tradición inglesa. Este bandido social, admirado por todos y en todas partes, que roba a los ricos y reparte el botín entre los pobres, actúa al margen de la ley y personifica asimismo la resistencia a la opresión social y una serie de virtudes más personales. En este artículo, vamos a analizar la forma en que el bandido inglés se ha convertido en un héroe mítico más que legendario. De hecho, el personaje de Robin Hood ha trascendido el tiempo y la cultura, y se ha convertido en el arquetipo del proscrito benevolente, un héroe popular nacido de las frustraciones de una clase inferior que considera que no hay leyes ni reglas en una sociedad injusta, sino la voluntad y el capricho de quien detenta el poder. [en] Throughout history, villains -whether real or imaginary- have served useful functions, especially those of “safety valves” for society. This is probably why many “villains” have been defined as “social bandits”, a term originally used by Eric Hobsbawm to refer to a type best exemplified in the Anglo-Saxon tradition by Robin Hood. This true and widely admired social bandit who steals from the rich and gives to the poor operates outside the law but at the same time personifies both group resistance to oppression and a number of more personal virtues. In this paper, we shall analyse the way in which the English bandit has become a mythical rather than a legendary hero. Indeed, the Robin Hood figure has transcended time and culture, and has become the archetype of the benevolent outlaw, a folk hero born of the frustrations of an underclass that sees the law as the will and whim of the privileged classes above them.

Results of a round-robin exercise on read-across

A round-robin exercise was conducted within the CALEIDOSLIFE project. The participants were invited to assess the hazard posed by a substance, applying in silico methods and read-across approaches. The exercise was based on three endpoints: mutagenicity, bioconcentration factor and fish acute toxicity. Nine chemicals were assigned for each endpoint and the participants were invited to complete a specific questionnaire communicating their conclusions.The interesting aspect of this exercise is the justification behind the answers more than the final prediction in itself. Which tools were used? How did the approach selected affect the final answer?
