    Chronicle of a forecast flood: exposure and vulnerability on the south‑east coast of Spain
    (Springer, 2022-06-09) Giménez García, Rubén; Ruiz Álvarez, Víctor; García Marín, Ramón; Geografía
    In recent years, floods have become one of the natural hazards that generate the greatest economic and human losses on the planet. As is well known, torrential rainfall events are the triggering factor for flooding processes; nevertheless, it is worth examining the responsibility of the human factor, such as urban development, in the occurrence of these potential natural disasters. To this end, rainfall observations obtained during different precipitation events have been analysed. The evolution and urban development from the growth of the number of buildings was also examined. The information obtained has been crossed with the digital cartography of flooded areas (National System of Flood Zones Cartography, SNCZI in Spanish acronym). The results obtained show that the last two extraordinary rainfall events (December 2016 and September 2019) that occurred in the municipalities of Los Alcázares and San Javier (Region of Murcia, SE Spain) exceeded 200 mm, and quantified very high hourly intensities (> 50 mm/h). On the other hand, the number of buildings constructed and the built-up area in both municipalities has increased notably, with an evolution between 1950 and 2019 from 1057 to 15,969 buildings constructed, increasing from 16.09 ha. to 450.06 ha. occupied. This real estate development has caused the number of buildings exposed to flooding to reach 3840 in 2019 for a 10-year RP (return period) and 5941 for a 500-year RP. It can be concluded by indicating the clear influence of territorial transformation on the increase of exposure and economic losses generated by flood events

    Community, exposed singularity and death in Mrs Dalloway.
    (Universidad de Murcia, Servicio de Publicaciones., 2024) López Sánchez-Vizcaíno, María Jesús
    This essay brings Virginia Woolf and Jean-Luc Nancy into dialogue, focusing on their similar critique of essentialized models of community and evocation of forms of being-with that derive from the experiences of singularity and death. It identifies two forms of community in Woolf’s novel Mrs Dalloway (1925). The first one corresponds to Nancy’s conception of the immanent community, built upon essence and fusion, and in which death is provided with an ideological meaning. In Woolf’s novel, this communitarian logic traverses the official, ritualistic way in which England has sublimated the death and loss caused by the First World War, and the repressive conventions and the authoritarian spirit of the governing classes. An alternative kind of community, however, is suggested in Mrs Dalloway, one that can be identified with Nancy’s conception of the inoperative community: a community of singular beings who share their finitude, exposure and death. Blanchot’s ideas on the transient community of lovers and Butler’s theorization of a ‘we’ based upon common vulnerability and loss also shed light on this novel’s concern with antisocial bonds between characters that escape traditional forms of affiliation.

    (Ex)poniendo el cuerpo: espacios, transiciones y resistencias
    (Departamento de Filosofía y Sociología. Facultad de Ciencias Humanas y Sociales. Universitat Jaume I (España), 2022-03-13) Gómez Prada, Hernando C.; Varela-Manograsso, Agustina; Bote, Marcos; Filosofía
    La transición experimentada por las personas trans agita las concepciones de las ciencias sociales respecto al entendimiento del tiempo y el espacio como unidades de análisis ancladas en axiomas biológicos y físicos tradicionales. La superación del binarismo sexual implica también el cuestionamiento del espacio y el tiempo como elementos aislados para ser entendidos como realidades entrelazadas. Tomando en consideración las concepciones de temporalidad y espacio queer de Halberstam y los estudios trans, el presente artículo alinea el relato individual de un hombre trans con diversidad funcional y trastornos del espectro autista (TEA) (mediante la implementación de la historia de vida como metodología inclusiva) con las trans-formaciones sociales, al vincular la exposición del cuerpo a la transgresión del tiempo cis heteronormativo, para ser reemplazado, paulatinamente, por una temporalidad trans y descubrir nuevas formas de cohabitar los espacios.

    Influencia de la sabina (Juniperus Thurifera) sobre el estrato herbáceo en función de la orientación
    (Murcia: Universidad de Murcia, Servicio de Publicaciones, 1989) Tárrega, R.; Luis, E.; Facultad de Biología
    Se estudia el efecto de la sabina (Juniperus thurifera) sobre el estrato herbáceo más próximo a ella. Para ello se realizan inventarios con una unidad de muestre0 cuadrada de 25 cm de lado, según transecciones en los cuatro rumbos principales a partir de la base de 10 árboles, elegidos aleatoriamente. Los datos así obtenidos se comparan mediante un análisis de afinidad y un análisis factorial en componentes principales. También se determina la diversidad u y y. Se observa una mayor homogeneidad en la composición específica de la vegetación más cercana al árbol, con pocas especies muy adaptadas a las especiales condiciones creada,por él y por tanto dominantes. Entre ellas destacan Bromus erectus y Brachypodium pinnatum subsp. rupestre. Al aumentar la distancia al árbol disminuye el efecto de dominancia, incrementándose la diversidad. Este aumento se manifiesta generalmente de modo progresivo desde los primeros inventarios. La particular importancia del efecto de sombra, dentro del conjunto de complejos factores mediante los cuales el árbol influye sobre el estrato herbáceo, se pone de manifiesto por una mayor y más clara influencia en dirección norte.

    Reliable and sensitive analytical platform to assess dietary exposure of pigs to mycotoxins and explore potential urinary biomarkers
    (Elsevier, 2024-12-24) Castell Martínez, Ana; Arroyo Manzanares, Natalia; Campillo Seva, Natalia; Sanz Fernández, Santos; Rodríguez Estévez, Vicente; Roquet, Josep; González, Antonio; Fenoll, José; Viñas López-Pelegrin, Pilar; Química Analítica
    A reliable and sensitive analytical platform is proposed for the assessment of pig exposure to mycotoxins through the consumption of commercial feed. A total of 48 naturally contaminated feed and 55 urine samples collected from eight Spanish farms were analyzed using a fast and simple methodology based on solid-liquid extraction (SLE) or liquid-liquid extraction (LLE) and dispersive liquid-liquid microextraction (DLLME). High-performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS/MS) was used for the targeted analysis of 27 mycotoxins from different families in both matrices achieving limits of quantification in a range of 0.019–73.5 ng/g in feed and 0.011–31.7 ng/mL in urine. All feed samples showed contamination with at least 7 mycotoxins. Enniatins (A, A1, B and B1) and beauvericin were quantified in 100 % of feed samples. ENNB, tenuazonic acid (TeA) and deoxynivalenol (DON) were the mycotoxins with the highest mean total concentrations (1.0 ± 1.9 μg/g, 155 ± 209 ng/g and 81 ± 94 ng/g, respectively). In urine samples, DON, TeA, ENNB1 and ENNA were the most prevalent mycotoxins; and TeA, fumonisin B1 and alternariol had the highest mean total concentration (133 ± 199 ng/mg, 0.43 ± 1.3 μg/mg and 0.29 ± 1.3 μg/mg creatinine, respectively). Statistical tests revealed the correlation of DON and TeA occurrence in feed and urine. Untargeted analysis byHPLC coupled to quadrupole-time-of-flight mass spectrometer (Q-TOF-MS) yielded some urinary biomarkers of mycotoxin exposure and other relevant compounds such as certain antibiotic residues in urine.
