El pintor Antoni Viladomat i Manalt (1678-1755): Biografia i Catàleg crític

La tesi és un estudi integral de la figura i l'obra del pintor Antoni Viladomat i Manalt (1678-1755), un dels artífexs més destacats del panorama artístic català del Set-cents. El primer volum aborda la revisió de la seva biografia partint de les aportacions de la historiografia i de les noves dades inèdites d'arxiu. S'hi fa també un anàlisi de la seva cultura visual i figurativa, una panoràmica sobre la relació del pintor amb el seu ambient artístic més proper i immediat, i un estudi de l'encaix de la seva personalitat artística en el context de la pintura precedent i contemporània peninsular i europea. El primer volum inclou, també, un epíleg on s'aborden temes com els detonants i les conseqüències de la seva extraordinària fortuna crítica. El segon volum és un catàleg crític de la seva obra, organitzat a partir de fitxes individuals de cadascuna de les obres. L'autor considera que dues-centes cinquanta obres conservades, comptant dibuixos i pintures, són autògrafes, quaranta-una de les quals són inèdites. El catàleg també te recull i classifica les obres descartades i les perdudes. Les principals aportacions de la tesi, a banda de l'actualització del coneixement de la seva biografia i de l'elaboració per primera vegada d'un catàleg crític complet de la seva obra, són la localització del testament del pintor, la revisió de la relació de Viladomat amb els artistes de la cort de l'Arxiduc Carles d'Àustria, la proposta d'una nova cronologia per als treballs dels anys vint del segle XVIII, una interpretació nova dels plets contra el col·legi de pintors de Barcelona, la revisió de la seva intervenció a la Capella dels Dolors de Santa Maria de Mataró, bona part de la qual l'autor d'aquesta Tesi atribueix al pintor Joan Gallart; la definició dels usos que el pintor fa amb l'estampa de traducció, la relació amb la pintura siscentista dels Juncosa o la importància de l'aprenentatge en un context tradicional, etcètera.

Realidade em crise: uma cobertura in loco da crise econômica na Espanha

Em um contexto globalizado, onde os acontecimentos possuem alcance mundial, torna-se necessário avaliar a eficiência do chamado Jornalismo Internacional na divulgação de informações. A singularidade do olhar jornalístico tem sido comprometida neste ramo, uma vez que a modalidade está cada vez mais ligada às agências de notícias, que apresentam uma cobertura pasteurizada dos assuntos em questão. O objetivo geral deste projeto foi contribuir para o enriquecimento das informações sobre a crise de origem econômica na Espanha, por meio da produção de conteúdo in loco, e retratar os reflexos deste contexto na vida da população europeia, nos âmbitos cultural, econômico, político e social, a fim de comprovar que é fundamental a presença do correspondente no local do assunto reportado. Além disso, constatou-se ser necessário reportar os efeitos da crise na vida comum dos habitantes da Espanha, uma vez que os meios de comunicação tradicionais se limitam a fornecer uma visão tecnicista do assunto, por meio de números e estatísticas. As notas, notícias, entrevistas, fotos e vídeos produzidos foram publicados em uma página experimental criada no Facebook, de modo a avaliar a eficácia das redes sociais enquanto novas plataformas do jornalismo digital

Desarrollo de las técnicas de producción de larvas de bocinegro (Pagrus pagrus) en Canarias

The incorporation of new marine species in aquaculture is esencial to development of this activity. The recent advances on the establishment oftechniques to produce red porgy (Pagrus pagrus), allow to consider it as a strong potencialto aquaculture, being predictable its implement in the Canary Archipel. Neverthe!ess, so far it is not posible to produce it comercially, due to difficulties in assuring a continual supply of larvae and fry. Knowing this, it is crucialto continue studying the production techniques oflarvae and the feeding system during this periodo For this, the aim of tbe work is to optimize production

Crecimiento y supervivencia de paralarvas de O. vulgaris cultivadas bajo diferentes intensidades de luz.

[EN] Paralarval rearing constitutes the main bottleneck to the complete development of octopus culture. This paper try to optimise the larval rearing conditions of Octopus Paralarvae, testing the effect of light intensity (1000, 3000 and 6000 lux ) over growth and paralarval survival. Four fibber glass tanks, 100 litter capacity with an initial density of 20 ind./litter were used for each treatment. All light treatments were fed with the same protocol, just hatching Maja Squinado Zoeas and Artemia metanaulios (72 hours)enriched with a commercial emulsion (Red Pepper Paste, Bernaqua, bva; Belgium). Better growth and survival were found with the highest light intensity treatment.

La renuncia al ejercicio de la acción social de responsabilidad

En el presente estudio se aborda un tema, el del régimen jurídico de la renuncia a la acción social de responsabilidad, que ha sido objeto de un escaso tratamiento por parte de la doctrina española. Estamos ante una institución controvertida, que regula la posibilidad de que una sociedad de capital abandone voluntariamente las pretensiones indemnizatorias que pudiera ostentar frente a alguno de sus administradores por los daños que éstos hubieran ocasionado en el patrimonio social como consecuencia del incumplimiento sus deberes de diligencia y lealtad. El hecho de que una sociedad de capital pueda acordar esta renuncia es un claro indicio del carácter dispositivo de las normas que regulan la responsabilidad de los administradores frente a la sociedad. Después de abordar de los antecedentes y evolución histórica de la renuncia a la acción social, la primera parte del estudio se centra en el análisis del ámbito material y temporal de su régimen jurídico, concluyendo que éste regula no sólo la renuncia o la transacción procesal, sino que se aplica cualquier acuerdo de la junta general que tenga como efecto una exoneración total o parcial de los administradores. La segunda parte del estudio profundiza en el régimen jurídico de la renuncia, haciendo hincapié en el derecho de veto que la Ley española y el Codice civile reconocen a la minoría y que se configura como una auténtica excepción al principio mayoritario que rige, con carácter general, la formación de la voluntad social. En el último capítulo se analizan los efectos de la renuncia acordada por la junta sobre la legitimación extraordinaria que ostentan los socios minoritarios y los acreedores sociales para el ejercicio de la acción social.

Optimization of laser-firing processes for silicon-heterojunction solar-cell back contacts

One of the key steps to achieve high efficiencies in amorphous/crystalline silicon photovoltaic structures is to design low-ohmic-resistance backcontacts with good passivation in the rear part of the cell. A well known approach to achieve this goal is to use laser-fired contact (LFC) processes in which a metal layer is fired through the dielectric to define good contacts with the semiconductor. However, and despite the fact that this approach has demonstrated to be extremely successful, there is still enough room for process improvement with an appropriate optimization. In this paper, a study focused on the optimal adjustment of the irradiation parameters to produce laser-fired contacts in a-Si:H/c-Si heterojunctionsolarcells is presented. We used samples consisting of crystalline-silicon (c-Si) wafers together with a passivation layer of intrinsic hydrogenated amorphous silicon (a-Si:H(i)) deposited by plasma-enhanced chemical deposition (PECVD). Then, an aluminum layer was evaporated on both sides, the thickness of this layer varied from 0.2 to 1 μm in order to identify the optimal amount of Al required to create an appropriate contact. A q-switched Nd:YVO4laser source, λ = 532 nm, was used to locally fire the aluminum through the thin a-Si:H(i)-layers to form the LFC. The effects of laser fluences were analyzed using a comprehensive morphological and electrical characterization.

System Integration in a UAS design. An example of undergraduate student's tasks.

Systems integration is the origin of most major difficulties found in the engineering design of aeronautical vehicles. The whole design team must assure that each subsystem accomplishes its particular goals and that, together with the rest of the systems, they all meet the general aircraft requirements.Design and building of UAS is a field of actuation to which leading Universities, research Centers and Aeronautical designers have dedicated a lot of effort. In recent years, a team of students, lecturers and professors at the Escuela Universitaria de Ingeniería Técnica Aeronáutica (EUITA) have been working on the design and building of a UAS for civil observation. The design of multi-mission Unmanned Aerial Vehicles (UAVs) has seen a rapid progress in the last years. A wide variety of designs and applications, some of them really ingenious, have been proposed. The project, which has been going on as a teamwork experience for the last ten years, consists of the design and building of a UAV, and its peculiarity is that it has been carried out entirely by undergraduate students, as part of their Final Research Project. The students face a challenge that includes all the features and stages of an authentic engineering project. We present the current moment of evolution in the process, together with a description of the main difficulties the project has undergone, as a global experience in engineering design and development.

Absorción acústica a incidencia normal de espumas de aluminio

En este artículo se presentan los primeros resultados de absorción acústica a incidencia normal de espumas de aluminio fabricadas mediante una técnica pulvimetalúrgica. El interés de estas espumas radica en que en ellas se combinan interesantes propiedades acústicas y mecánicas. Se estudian espumas de aluminio de distinta morfología superficial conseguida variando el tipo de precursor y usando materiales de relleno durante el proceso de espumación. Se muestra un estudio comparativo de las espumas fabricadas mediante esta técnica con las espumas comerciales ALPORAS. Las espumas de menor densidad presentan una absorción acústica comparable a la de las comerciales ALPORAS. ABSTRACT. In this paper, the first experimental data of acoustic absorption at normal incidence in aluminum foams generated by a metallurgic technique are presented. The interest of this kind of structures is due to the combination of mechanical and acoustic properties. By changing the precursor type or using filling materials during the foaming process, we have obtained aluminum foams with different surface morphologies. A comparative study between foams fabricated using this technique and ALPORAS commercial aluminum foams is shown. The foams which present the lower density show an acoustic absorption comparable to the ALPORAS commercial ones.

Experimental investigation on box-wing configuration for UAS

The range for airframe configurations available for UAS is as diverse as those used for manned aircraft and more since the commercial risk in trying unorthodox solutions is less for the UAS manufacturer. This is principally because the UAS airframes are usually much smaller than the manned aircraft and operators are less likely to have a bias against unconventional configurations. One of these unconventional configurations is the box-wing, which is an unconventional solution for the design of the new UAS generation. The existence of two wings separated in different planes that are, however, significantly close together, means that the aerodynamic analysis by theoretical or computational methods is a difficult task, due to the considerable interference existing. Considering the fact that the flight of most UAS takes place at low Reynolds numbers, it is necessary to study the aerodynamics of the box wing configuration by testing different models in a wind tunnel to be able to obtain reasonable results. In the present work, the study is enhanced by varying not only the sweepback angles of the two wings, but also their position along the models’ fuselage. Certain models have shown being more efficient than others, pointing out that certain relative positions of wing exists that can improve the aerodynamics efficiency of the box wing configuration.

Project based learning activities as a means of adapting conventional curricula to the demands of the 21st century aeronautical engineer: The design and building of the EYEFLY 1.

In this paper we report the process of designing and building the EYEFLY 1, a real UAS platform which has just performed its maiden flight. For the development of this aircraft, 30 groups of students from successive years at the Escuela Universitaria de Ingeniería Técnica Aeronáutica (EUITA) of the Universidad Politécnica de Madrid (UPM) carried out their compulsory End of Degree Project as a coordinated Project Based learning activity. Our conclusions clearly indicate that Project Based Learning activities can provide a valid complement to more conventional, theoretically-based, teaching methods. The combination of both approaches will allow us to maintain traditional but well-tested methods for providing our students with a sound knowledge of fundamental engineering disciplines and, at the same time, to introduce our students to exciting and relevant engineering situations and sceneries where social and business skills, such as communication skills, team-working or decision-taking, can be put into practice.
