Sebastião Rodrigues: hijo de Lisboa y padre del diseño portugués

A lo largo del siglo XX, el diseño gráfico portugués recaía en los pintores y arquitectos. Dicha disciplina no se consolidó como tal hasta los años 70, con la ayuda de relevantes personajes como Sebastiāo Rodrigues. El artista lisboeta es considerado el mayor icono del diseño en Portugal y las gráficas publicitarias que realizó para la Fundación Calouste Gulbenkian lo reafirman. El presente trabajo pretende mostrar la imagen de Rodrigues, su vida, obra y estética. Asimismo, es necesario reflejar una correcta contextualización sobre la situación en la que se desenvolvió su trabajo.Grado en Publicidad y Relaciones Pública

Thermal suspectability analysis of the reuse of fly ash from cellulose industry as contribution filler in bituminous mixtures

The increased population has accelerated pavement deterioration of and boosted production of residues, generating a constant environmental problem. One of the main problems of pavements is a failure to develop union between bituminous mastic ligand and aggregate. The following study evaluates the use of ash from cellulose incineration as a contribution filler to improve thermal susceptibility of pavements in different climatic zones. The applied methodology for dosage was based on volumetric criteria and state curves. The obtained results showed that reusing this residue in determined conditions (Cv/Cs???1) offers lower wear loss to 35% of temperatures between ?10 and 60?°C, due to the Cv/Cs?=?0.75 ratio that maximizes the cohesive properties of the mixture. Therefore, we showed that this type of industry residue can be reused without complication in zones of certain climatic criteria and that it provides improved properties to the asphalt mix compared to conventional mixes

Effect of copper slag addition on mechanical behaviour of asphalt mixes containing reclaimed asphalt pavement

Annually, copper production and refining processes of generate large volumes of copper slag, and the disposal of this waste remains a major economic and environmental problem. This annual production causes an increase in the number and volume of landfills, as well as the quantity of slag that backs up landfills, it also produces leachates which contain metals such as Cu, Pb, Hg and SO2. In this research, friction and cohesive qualities of copper slag are exploited, in order to incorporate this slag as aggregate in asphalt mixes containing Reclaimed Asphalt Pavement (RAP). Results demonstrate that the use of copper slag in an addition percentage of 35% is favorable, because flow values increase and stability values decrease. The Marshall Quotient is reduced up to 27%, improving the performance of mixes with RAP and obtaining behavior similar to a traditional mixture. This improvement is also reflected in an 8% increase in the indirect tensile strength, which stands the use of copper slag as a solution in RAP applications with more demanding tensile and fatigue requirements.The presented results are part of the FONDECYT Initiation into Research project No. 11140889, funded by CONICYT-Chile, and the DID S-2014-27 project, funded by the Universidad Austral de Chile.

Development of an estimative model for the optimal tack coat dosage based on aggregate gradation of hot mix asphalt pavements

In this work the performance of tack coats on asphalt pavement layers is analysed. Adjustment models based on experimental measurements were implemented, relating surface layer macro-texture and aggregate content larger than 8 mm. The best fits were obtained with a Gompertz model, which follows the expected physical macro-texture changes outside the test range. Shear strength was analysed, through prediction curves of each evaluated tack coat dosage, with an optimum tack coat performance for aggregate contents larger than 8 mm between 45% and 50%, and no relevant influence of the tack coat dosage used.The authors would like to acknowledge the support provided by the Technologic Research Construction Group (GITECO) and the Group of Roads of Santander at Cantabria University for the development of tests and samples.

La subtitulación amateur: la subtitulación amateur de series online: el caso de Lost

Curs 2011-2012Debido a su gran repercusión y rápido ritmo de expansión, resulta obvio que la subtitulación amateur se configura como uno de los fenómenos más interesantes y novedosos de los estudios teóricos y prácticos de la investigación traductológica. Por este motivo, el objetivo principal del presente trabajo es el de conocer y estudiar más en profundidad dicho fenómeno, así como analizar la calidad de estos subtítulos con relación a los profesionales a través de un análisis comparativo de materiales reales de la serie norteamericana Lost. Por otro lado, y a la vista de las conclusiones, también se reflexiona acerca del estado actual de la subtitulación interlingüística, así como de la viabilidad de llevar a cabo una modernización de la disciplina mediante el establecimiento, renovación y diversificación de nuevas y existentes modalidades, junto con las repercusiones académicas, sociológicas y profesionales que ello acarrearía.Due to its great impact and rapid growth, it seems obvious that amateur subtitling is one of the most interesting and groundbreaking phenomena of the theoretical and practical aspects of Translation Studies.

On the other hand, and in view of the conclusions drawn, it also offers a reflection about the current state of interlinguistic subtitling, as well as on the feasibility of modernizing the discipline through the establishment, renewal, and diversification of new and currently existing subtitling typologies within audiovisual translation, taking into account, besides, the academic, sociological, and professional consequences that this may imply.Director/a: Francesca Bartrin

Use of plastic scrap in asphalt mixtures added by dry method as a partial substitute for bitumen

In recent decades, the generation of plastic waste has increased substantially worldwide, with the result that more of such waste is introduced into the environment. Currently, most polymers (polyethylene terephthalate, polyethylene, polyvinyl chloride, and others) are recycled. However, some are rejected for recycling in the primary separation processes due to their physical condition, contamination, or size. These materials are called plastic scrap. In this research, the use of plastic scrap added by dry method was evaluated as a replacement for bitumen in asphalt mixtures. Two sizes of plastic scrap, coarse and fine, were considered. An AC16S semi-dense mixture was designed for this purpose, with a 10% reduction in binder, and 10% and 20% of plastic scrap binder was added in coarse and fine sizes. The results obtained in the Marshall stability and flow test showed reduced moisture damage, greater indirect tensile strength, higher air void content, and a 2% decrease in the conserved tensile strength ratio while the same usage field as the conventional mixture was maintained. Meanwhile, significant decreases in plastic deformations, as compared to traditional values, were obtained from resilient modulus and rutting tests

Effects of high temperature on survival, symbiotic performance and genomic modifications of bean nodulating Rhizobium strains.

High temperatures can affect the survival, establishment and symbiotic properties of Rhizobium strains. Bean nodulating Rhizobium strains are considered particularly sensitive because on this strains genetic recombinations and/or deletions occur frequently, thus compromising the use of these bacteria as inoculants. Rhizobium tropici and R. leguminosarum bv. phaseoli strains isolated from cerrado soils were exposed to thermal stress and the strains' growth, survival and symbiotic relationships as well as alterations in their genotypic and phenotypic characteristics were analysed. After successive thermal shocks at 45 degrees C for four hours, survival capacity appeared to be strain-specific, independent of thermo-tolerance and was more apparent in R. tropici strains. Certain R. leguminosarum bv. phaseoli strains had significant alterations in plant dry weight and DNA patterns obtained by AP-PCR method. Rhizobium tropici strains (with the exception of FJ2.21) were more stable than R. leguminosarum bv. phaseoli strains because no significant phenotypic alterations were observed following thermal treatments and they maintained their original genotypic pattern after inoculation in plants.

The use of copper slags as an aggregate replacement in asphalt mixes with RAP: Physical-chemical and mechanical behavioural analysis

Copper slag (CS) is a derivative of copper production that is mainly composed of heavy metals. The large amount of this material accumulated around the world entails a serious environmental danger. Its use as a replacement of mineral aggregate in asphalt mixtures would allow to increase the durability and resistance, taking advantage of its physical-chemical properties. In this research, physicochemical analyses of different combinations of CS, reclaimed asphalt pavements (RAP), asphalt cement and aggregates by X-Ray Diffraction (XRD) and Fourier-Transform InfraRed spectroscopy (FT-IR) were developed. Subsequently, Marshall stiffness ratio, indirect tensile strength (IDT) and resilient modulus tests were performed to determine their implication in mechanical behaviour. Asphalt mixes with ranges from 45 to 55% of recycled material have improved stability, Marshall Flow and Stiffness ratio, obtaining values comparable with those from a conventional mixture. At the same time, its resilient modulus and IDT values increased by 35% compared to conventional mixes. To maintain values similar to conventional mixes, when the amount of RAP decreases the amount of CS should be increased, with a maximum value of 35%. This behaviour is explained by the presence of fayalite and magnetite in CS, which are hard, dense and hydrophobic components that produce increased elastic deformation of the binder before breaking.These results are part of a project funded by: the Universidad Austral de Chile [DID S-2014-27]; and a CONICYT-Chile project [FONDECYT Initiation into Research No. 11140889]
