Spanish primary school buildings are likely to present a high seismic vulnerability. This is due to two main factors: (a) most of them were built prior to the enforcement of the Spanish seismic codes; (b) the elevated child-to-adult ratio compromises the effectivity of the evacuation plans. In this work, the schools of the Spanish province of Huelva, mainly reinforced concrete framed buildings from the 70s, were studied. First, a general classification based on the structural type and overall geometry of the building was made. Next, several characteristics of the buildings that could influence their seismic response have been analysed through a sensitivity analysis. This paper focuses on one of the characteristics studied: the existence of an atrium (an observed recurrent irregularity) and its position. Different versions of the index building model, varying the position of the atrium, have been analysed. Non-linear static analyses were used to study the seismic performance of the models. Results have shown that if the atrium is located in the short direction of the building, it improves its seismic performance, in most of the cases. However, the addition of one or more atriums in the long direction of the building diminishes the global strength of the building. Finally, it should be mentioned that torsional effects appear when the atrium is not located next to the centre or the surface occupied by the atrium is large. Therefore, the existence and position of the atrium must be carefully considered for a safe seismic design.

Trabajo presentado en: EIFS2022, the 2nd Iberian Meeting on Supercritical Fluids (2º Encontro Ibérico de Fluidos Supercríticos / 2º Encuentro Ibérico de Fluidos Supercríticos), to be held on 28.February - 2.March 2022 in Coimbra, Portugal., Nowadays, the society is immersed in the transition from a linear to a circular economy, in which the value of products, materials and resources is maintained in the economy for as long as possible and the generation of waste is minimized. This means that the byproduct of a process becomes the input of a new one where it acquires new value. Among other agricultural by-products, onion (Allium cepa L.) skin wastes offer great potential for valorization. Onion is the second most important horticultural crop worldwide. More specifically, Spain, in the year 2018 produced 1.27 Mt [1]. The onion industry generates every year more than 0.5 Mt of Onion Skin Wastes (OSW) worldwide [2], including skins (the outermost layers), roots and bulbs unfit for consumption. The non-edible brown skin and external layers of onions are rich in phenolic compounds, mainly flavonoids such as quercetin (QC) [3] and its derivatives: quercetin 4’-O-β- glycoside (QC4’), quercetin 3,4’-O-β-diglycoside (QC3,4’) and quercetin 3-O-β- glycoside (QC3). All of them are high-added value natural antioxidants [2]. The main drawback of quercetin and quercetin derivatives is the limited solubility in water, which limits their oral bioavailability [4] and extractability, and forces the use of an organic solvent to successfully extract them. Alternatively, Subcritical Water (SubW) can be used to extract flavonoids from onion skins. SubW refers to water at temperatures ranging from 100 °C (boiling point) to 374 °C (critical point) which remains in a liquid state due to the application of pressure. Changes in the working conditions change the properties of the SubW (among them, viscosity, surface tension and dielectric constant, which can be similar to those of some organic solvents), enhancing mass transfer and the extractability of barely water-soluble bioactive compounds, as summarized by Benito-Roman et al. [5], as SubW favors the hydrolysis of the bonds between phenolic compounds and the vegetable matrix. In this work the extraction, identification and quantification of phenolic compounds from OSW has been studied using SubW in a semicontinuous extractor (flow rate constant and equal to 2.5 mL/min; temperatures up to 180 °C with working pressure of 5 MPa, to keep water in liquid state). The extraction of flavonoids resulted to be fast (, This work was supported by AEI [PID2019-104950RB-I00 and PID2020-116716RJ-I00] and JCyL and ERDF [BU050P20] [BU301P18]

Orientadores: Artemis Maria Francelin Sanches Moroni, Hermes Renato Hildebrand Dissertação (mestrado) - Universidade Estadual de Campinas, Instituto de Artes Resumo: Este trabalho apresenta um estudo sobre a multisemiose e a interatividade na web arte. Neste estudo observamos os usos desses conceitos em algumas obras brasileiras concebidas especificamente para a internet. O corpo da dissertação possui a seguinte estrutura: primeiramente, refletimos sobre como a descentralização da produção e distribuição de conteúdos na internet trouxe novas discussões para o campo das mídias e das artes, e sobre como a multisemiose e a interatividade são aspectos característicos do hipertexto relevantes neste novo contexto. Apresentamos cada um desses termos separadamente, listando as referências teóricas que utilizamos em relação a cada um deles. Em seguida refletimos sobre os usos desses conceitos em obras de web arte criadas por artistas brasileiros. Analisamos o uso da multisemiose e da interatividade na obra de web arte Imaterial, de Marília Coelho e Bruno Kurru, sob a Teoria Semiótica de Charles Peirce. Por fim, apresentamos as reflexões que desenvolvemos com base nos estudos realizados Abstract: This work presents a study about multisemiosis and interactivity in web art.
