Curanderos, sanadores y santiguadoras en Lanzarote entre los siglos XVI y XIX

[ES] Curanderos y sanadores nacieron ante la necesidad de hacer frente a los escasos medios que tenía la isla para curar sus enfermedades, la poca confianza que les daban los conquistadores y sobre todo ante la aparición de nuevas epidemias y plagas, que año tras año dejaban los visitantes y transeúntes. Partiendo de la premisa de que la “magia” popular es utilitaria, un medio para lograr un fin.

Tratamientos de depuración de aguas residuales contaminadas con pesticidas

[ES] En el presente trabajo se ha comparado la eficiencia de los tratamientos biológicos y fotocatalíticos en la depuración de aguas contaminadas con dos pesticidas: Pirimetanil y Triadimenol, ampliamente utilizados como fungicidas sistémicos en la lucha contra plagas de hongos en los cultivos de tomate de la isla de Gran Canaria. Ambos compuestos son considerados tóxicos para organismos acuáticos, hecho que justifica la necesidad de estudiar un tratamiento efectivo de depuración de aguas residuales que los contengan, antes de proceder a su vertido. Paralelamente, se ha llevado a cabo el mismo estudio con otro contaminante orgánico: Resorcinol, con mayor biodegradabilidad que los pesticidas estudiados. Los resultados obtenidos en el presente trabajo indican que las aguas contaminadas con ambos pesticidas deben ser tratadas mediante procesos fotocatalíticos, mientras que, en el caso de Resorcinol, el tratamiento debe ser mediante procesos de depuración biológicos.

Photocatalytic degradation of phenolic compounds with new TiO2 catalysts

[EN] New TiO2 catalysts have been synthesised by means of a sol–gel method in which aggregates have been selected before thermal treatment. Sieving and calcination temperature have been proved to be key factors in obtaining catalysts with greater photoactivity than that of Degussa P-25. These new catalysts have been characterized by means of transmission electron microscopy (TEM), BET surface area, diffuse reflectance spectroscopy (DRS), UV–vis spectroscopy, Fourier transformed infrared (FTIR) and X-ray diffraction (XRD). The different parameters studied were compared to those obtained from two commercial catalysts (Degussa P-25 and Hombikat-UV100). The photocatalytic efficiency of the new catalysts was evaluated by the degradation of various phenolic compounds using UV light (maximum around 365 nm, 9mW). The catalyst sieved and calcinated at 1023 K, ECT-1023t, showed phenol degradation rates 2.7 times higher than those of Degussa P-25. Also in the degradation of different phenolic compounds, this catalyst showed a higher activity than that of the commercial one. The high photoactivity of this new catalyst has been attributed to the different distribution of surface defects (determined from FTIR studies) and its increased capacity to yield H2O2

Oceanográfica: más de una década generando libros para la divulgación de las ciencias del mar

[ES]Con motivo de la celebración del Día Internacional del Libro 2014 la empresa canaria de divulgación de obras de divulgación científica sobre las ciencias del mar, Oceanográfica, nos cuenta cómo lo han hecho y porqué se han auditado conforme a los principios de la Economñia del Bien Común. Una de las razones del éxito obtenido parece residir en el maridaje del trabajo editorial con contenidos de calidad proporcionado por los científicos con vocación de divulgar dicho conocimiento

Eliminación de microcontaminantes orgánicos mediante tratamientos avanzados para un uso potable indirecto de aguas regeneradas

[ES]En este trabajo se ha evaluado la utilización de procesos avanzados en la obtención de agua regenerada para un uso potable indirecto. Se ha investigado la eficacia de procesos de oxidación avanzada (UV/H2O2) y (UV/TiO2), así como de adsorción sobre carbón activado, en la eliminación de 23 fármacos presentes habitualmente en aguas tratadas por tratamientos convencionales en EDAR urbanas, en concentraciones del orden de ng/L. El tratamiento con UVC y H2O2 resultó ser más eficiente que la fotocatálisis con TiO 2, ya que elimina el 100% de los fármacos estudiados. La presencia de materia orgánica y bicarbonato en agua microfiltrada procedente de un tratamient o de lodos activados, limitan la aplicación de la fotocatálisis heterogénea debido al envenenamiento de la superficie del catalizador así como a una competencia de los componentes del agua y los contaminantes en las reacciones con las especies oxidantes generada.

La medida del síndrome de Burnout en deportistas: una perspectiva multidimensional

[ES] El objetivo fundamental de este trabajo es comparar dos instrumentos de medida del burnout en deportistas: el Inventario de Burnout en Deportistas-Revisado (IBD-R) y el Athlete Burnout Questionnaire (ABQ). Ambos modelos de medida asumen una composición tridimensional del síndrome existiendo supuestamente un paralelismo conceptual entre dimensiones. Los análisis de correlaciones realizados entre subescalas supuestamente equivalentes muestran, no obstante, que sólo existe un buen grado de convergencia entre una de las subescalas (Agotamiento Emocional del IBD-R y Agotamiento Físico y Emocional del ABQ). Otras dos subescalas que deberían converger (Reducida Realización Personal del IBD-R y Reducida Sensación de Logro del ABQ) muestran un grado de convergencia menor del esperado y las subescalas de Despersonalización del IBD-R y Devaluación de la Práctica Deportiva del ABQ apenas evidencian relación. Las disonancias teóricas y psicométricas observadas nos hacen reflexionar acerca de desarrollo de un nuevo modelo que integre los componentes del burnout no convergentes.

Determinants of specific food consumption in the Canary Islands (Spain)

The consumption of specific functional foods (FF) and some determinants of FF item selection were assessed using a questionnaire administered to 1112 individuals in the Canary Islands (Spain). Food items considered were Milk products: easily digestible milk (or milk low in lactose), milk enriched with vitamins and/or minerals, skimmed milk with soluble fiber, milk with royal jelly, milk with modified fatty acids (omega 3), milk products low in fat, pro-biotic foods (yoghurt and fermented milk) and yoghurt with phytosterols; Cereals: fortified breakfast cereals, wholemeal cereals and energy bars; Drinks: juices and enriched drinks, stimulating drinks and isotonic drinks; DHA-enriched, low cholesterol eggs; Meat products: low salt sausages and cooked low fat ham; Fats: enriched margarine, margarine rich in phytosterols and

Determinants of specific food consumption in the Canary Islands (Spain)

[EN]The consumption of specific functional foods (FF) and some determinants of FF item selection were assessed using a questionnaire administered to 1112 individuals in the Canary Islands (Spain). The results indicated that the highest prevalence was fortified drinks (63.6%; 95%CI: 60.7–66.5). Overall FF consumption prevalence was 80.1% (95%CI: 77–83): single FF item consumption being rare. There were significant inter-group relationships, and some group intakes (milk products, cereals and drinks) were related to age but with no overall relationship between consumption and age. The education level was significantly related to the consumption of cereals, drinks, meat products and condiments (c2 test p ¼ 0.04).

La hija de Cervantes: un dramma romantico inedito di Aureliano Fernández-Guerra y Orbe. Edizione critica e studio

Aureliano Fernandez-Guerra is known especially among Quevedo’s scholars because he published the first complete edition of Quevedo’s works. Few people know his plays and, for this reason, they have never been studied. These plays were written during his youth, when Fernández-Guerra hadn’t decided anything about his career yet. Therefore, these plays were always very important for him and, for this reason, he continued to correct and to revise them. Among them, the unpublished drama La hija de Cervantes (1840) was considered the most important play. In this doctoral thesis I have tried to describe this Spanish author, especially focusing on theatre. In the first part I wrote about the life and the literary works, giving particularly importance to his plays that are La peña de los enamorados (1939), La hija de Cervantes (1840), Alonso Cano (1842) and La Ricahembra (1845), this last one written in collaboration with Manuel Tamayo y Baus, another important and famous playwright. In the second part I deepened the study of La hija de Cervantes because it is a particular interesting drama: Aureliano Fernández-Guerra chose to represent the author of the Quixote as a character of his drama, especially dramatizing the most mysterious moments of his life, such as the Gaspar de Ezpeleta’s murder, his relationship with his daughter Isabel de Saavedra and his supposed love for a woman, whose existence his unknown. Besides, this drama is interesting because it is partially autobiographic: I found several letters and articles where it is emphasized the similarities between Cervantes’ and Aureliano’s life: both feel misunderstood and not appreciated by other people and both had to renounce a big love. In the final part I presented the critical edition of La hija de Cervantes based on the last three manuscripts that are today at the Institut de Teatre in Barcelona. A wide philological note shows the transcription criterions.

El guiño de lo real. Percorsi intertestuali nella narrativa di Cristina Rivera Garza

La tesi si occupa di analizzare la produzione narrativa della scrittrice messicana di frontiera Cristina Rivera Garza. In particolare, si pone l'accento sull'uso della strategia dell'intertestualità. A partire dalle fondamentali teorie classiche di Julia Kristeva, Gérard Genette e molti altri, lo scopo è quello di proporre un nuovo modello interpretativo che possa considerare la peculiarità della letteratura ispano-americana e inglobare la particolarità della proposta narrativa della scrittrice in oggetto. Attraverso l'innovativo studio di Roberto González Echevarría, l'obiettivo è quello di analizzare non solo i rapporti che si stabiliscono tra opere che appartengono al sistema della letteratura, ma anche i produttivi rapporti che si stabiliscono fra testi letterari e testi che non appartengono al sistema della letteratura. In particolare si analizza: a) le relazioni tra Storia e narrazione nel romanzo storico messicano tra XX e XXI secolo; b) le relazioni tra cronaca (considerata come genere tout court e come insieme di notizie giornalistiche) e narrazione nel romanzo poliziesco messicano contemporaneo.
