El mundo de los actores en el Siglo de Oro: estado de la cuestión
2013
En España contamos con un rico patrimonio documental que nos ayuda a reconstruir una buena parte de la actividad de los actores y de las compañías teatrales que se fueron profesionali-zando a partir de la década de 1540. La consolidación progresi-va a partir de la década de 1580 de los primeros recintos teatra-les comerciales (los llamados corrales, patios o casas de comedias), supuso un empuje decisivo para la organización de la profesión, y trajo aparejada una paulatina regulación sobre dife-rentes aspectos de esta actividad. Este proceso culminó con el reconocimiento oficial de la existencia de un gremio de actores, aprobado como tal en 1634.
Lope y la tramoya de la corte: entre tradición e innovación
2013
El trabajo se centra en el periodo de actividad de Lope de Vega como dramaturgo para reconstruir, con la reunión de datos conocidos y los aportados por algunos documentos de archivo, la actividad espectacular y festiva vinculada a la corte de los Austrias. El artículo hace balance de esa tradición espectacular, sobre la que cada vez se tiene mayor información, porque es ese telón de fondo el que permite entender y contextualizar cabalmente los grandes dramas-espectáculo escritos por Lope desde fechas tempranas y hasta poco antes de su muerte, y comprender las trasformaciones que supo imprimir a esa tradición. This paper focuses on the period of Lope de Vega’s activity as a playwright in ord…
Preceptiva y práctica teatral: 'El mayordomo de la duquesa de Amalfi', una tragedia palatina de Lope de Vega
2015
El mayordomo de la duquesa de Amalfi se publicó en la Parte XI de las comedias de Lope de Vega, en 1618.2 Lope no cita esta obra en la lista de sus comedias incluida en la primera edición de El peregrino en su patria (1604), aunque sí lo hará en la segunda (1618).3 Morley y Bruerton sitúan su composición entre 1599 y 1604, adscribiéndola más probablemente al periodo comprendido entre 1604 y 1606 (356-57). Hay un documento que confirma que efectivamente debió de escribirse por estas fechas. Se trata de un contrato de 22 de mayo de 1606, por el que la compañía del autor Alonso de Riquelme se comprometía a representar cuatro comedias en La Puente del Arzobispo (Toledo) durante las fiestas de S…
Overview of first Wendelstein 7-X high-performance operation
2019
Abstract The optimized superconducting stellarator device Wendelstein 7-X (with major radius , minor radius , and plasma volume) restarted operation after the assembly of a graphite heat shield and 10 inertially cooled island divertor modules. This paper reports on the results from the first high-performance plasma operation. Glow discharge conditioning and ECRH conditioning discharges in helium turned out to be important for density and edge radiation control. Plasma densities of with central electron temperatures were routinely achieved with hydrogen gas fueling, frequently terminated by a radiative collapse. In a first stage, plasma densities up to were reached with hydrogen pellet injec…
Structural assessment of a whole toroidal sector of the HELIAS 5-B breeding blanket
2021
Abstract The European roadmap for the realization of fusion energy considers the stellarator line as a possible long-term alternative to a tokamak DEMO. In this context, from the plasma physics standpoint, the most promising option is a five-field period power plant called HELIcal-axis Advanced Stellarator (HELIAS) 5-B. In order to allow the electricity production, the HELIAS 5-B reactor must be endowed with a breeding blanket (BB). Hence, in this paper, the advancements in the HELIAS 5-B BB design are reported. In particular, the structural assessment of a whole BB period, extending along toroidal direction for 72 °, is depicted. A geometric configuration encompassing dummy BB segments has…
Preliminary structural assessment of the HELIAS 5-B breeding blanket
2019
Abstract The European Roadmap to the realisation of fusion energy, carried out by the EUROfusion consortium, considers the stellarator concept as a possible long-term alternative to a tokamak fusion power plant. To this purpose a pivotal issue is the design of a HELIcal-axis Advanced Stellarator (HELIAS) machine equipped with a tritium Breeding Blanket (BB), considering the achievements and the design experience acquired in the pre-conceptual design phase of the tokamak DEMO BB. Therefore, within the framework of EUROfusion Work Package S2 R&D activity, a research campaign has been launched at KIT. The scope of the research has been the determination of a preliminary BB segmentation scheme …

Influence of spectral composition on the temperature coefficients of solar cells from Elkem Solar
2014
The temperature coefficients of solar cells from two different feedstocks — a compensated silicon, the Elkem Solar Silicon (ESS®), and polysilicon - under full and selective parts of the light spectrum are presented based on results obtained using a AAA sun simulator. These results are of particular interest in understanding the possible causes behind the better temperature coefficients usually observed for ESS® compared to polysilicon solar cells when measured with a full AM1.5 spectrum. The optical filtered lights from four different regions of the spectrum have been used to examine the influence of temperature coefficients on the spectral composition. ESS® solar cells showed considerable…
Some decisional problems on rational relations
1997
Abstract In this paper we prove that the problem of deciding whether a deterministic rational relation is star-free is recursively solvable, although the same problem for any rational relation is undecidable. We also prove that a rational relation is star-free if and only if it is aperiodic and deterministic.
Cultured Ito cells of rat liver express the alpha 2-macroglobulin gene.
1987
Ito cells were isolated from rat liver and kept in culture for up to 13 days. The capability of the Ito cells to synthesize a2-macroglobulin was analyzed at different times after isolation and by pulse-chase experiments. Newly synthesized a2-macroglobulin was determined by immunoprecipitation followed by sodium dodecyl sulfate/ polyacrylamide gel electrophoresis and fluorography. a2-Macroglobulin synthesis was hardly detectable in Ito cells and their media 3 days after plating. However, 5 - 11 days after the isolation of the cells, increasing amounts of a2-macroglobulin were synthesized. The results of pulse-chase experiments performed on day 7 showed that radioactively labeled a2-macroglob…
