    Este TFM se articula en torno a una propuesta didáctica de español para extranjeros (ELE) basada en la explotación didáctica de un largometraje de producción reciente. Para elaborarla, se ha recurrido a una revisión de numerosos estudios, otras propuestas didácticas sobre cine y documentos oficiales. Además, se ha llevado a cabo una observación de los grupos-clase donde se implantaría y se ha elaborado una encuesta sobre consumo cinematográfico dirigida a los alumnos. La propuesta resultante está formada por cuatro apartados, cada uno de ellos dedicado a un curso y nivel distintos, concretamente Years 10, 11, 12 y 13. Todas estas propuestas mantienen el cine como elemento central y buscan trabajar en el aula tanto aspectos lingüísticos como socioculturales. La contextualización tiene lugar en un instituto público de Reino Unido, en alumnado de entre 14 y 18 años que se encuentra en plena adolescencia. La película seleccionada es el largometraje de Pedro Almodóvar Madres paralelas (2021), que aborda temas como la maternidad temprana, el consentimiento afectivo-sexual y la identidad, tanto a nivel individual como social a través de la memoria histórica. La revisión teórica da lugar asimismo a una tabla que recopila y relaciona los objetivos y contenidos para la propuesta didáctica de dichos cursos extraídos del Marco Común Europeo de Referencia para las lenguas o MCER (2021), el Plan Curricular del Instituto Cervantes o PCIC (1997-2022), el Currículo inglés o The National Curriculum in England (2014) y los manuales de especificaciones para los exámenes conocidos como GCSE y A-Levels. En general, con este trabajo se pretende concienciar tanto a alumnos como a docentes de las múltiples ventajas de introducir el cine como detonante de temáticas transversales en la clase de ELE a adolescentes.This dissertation is built upon a lesson plan for the Spanish as a Foreign Language subject (ELE), which is based on the exploitation of a recent film as a educational resource. To elaborate the plan, an exhaustive review has been conducted over outnumbered studies, different lesson plans based on cinema and several official documents. Furthermore, a close observation of the groups where the plan would be implemented has been carried out, and a survey on cinema habits has been elaborated, addressed to students. The resulting lesson plan is composed of four parts, each of which is aimed to a different year with a specific level, concretely to Years 10, 11, 12 and 13. All these parts keep cinema as a central subject and seek for dealing with linguistic and sociocultural aspects as well. The contextualisation would take place in a group of students from a state school in United Kingdom who are between 14 and 18, in the mid-adolescence. The chosen film is Pedro Almodóvar’s Madres paralelas or Parallel Mothers (2021), which deals with topics such as early maternity, sexual consent and identity, both at an individual and a social level, the latter dealt with through historical memory. The theoretical framework also results in a chart which relates and compiles the objectives and contents corresponding to the four aimed years to elaborate the lesson plan. These are subtracted from the Common European Framework of Reference or CEFR (2020), the Plan Curricular del Instituto Cervantes or PCIC (1997-2022), The National Curriculum in England (2014) and the specifications for the GCSE and the A-Levels exams. In sum, this dissertation aims to raising awareness for both teachers and students about the multiple advantages of introducing cinema as a source to deal with cross-sectional matters in the Spanish subject with teenagers

    The growth in the use of novel materials, as it is the case of the Metal Matrix Composites (MMCs), is producing a positive impact in production processes, allowing to obtain final products with improved functionalities, such as an increase of the strength-to-weight ratio, or enhancement of the mechanical properties of the material, minimizing as well the environmental impacts and production costs without compromising the required technical properties. To determine and compare the environmental impact of different processes employing these materials, this paper provides a comparative analysis of the Life Cycle Assessment (LCA), under ISO 14040:2006 framework and European ILCD guidelines, of two different manufacturing technologies, Green Sand Casting (GSC) and Low Pressure Die Casting (LPDC), for the particular case of a self-cleaning doorknob, produced by an aluminium alloy reinforced with hard TiO2 nanoparticles, that confers special characteristics to the composite, such as an increase of the hardness value and tensile strength, a high wear resistance, a good chemical stability, and antibacterial properties. The results show a slight difference between both technologies in terms of kg CO2 eq. emitted, with just a 3,16 % variation, where GSC emissions are 13,098 kg, whereas 12,684 kg are released from LPDC. In addition, an economic analysis was performed, showing a 17 % cost reduction in case of LPDC. This study presents for the first time a comparative Life Cycle Assessment of GSC and LPDC, when employing new nanocomposite materials, contributing with novel datasets and meaningful insights to improve the state of the art in the field, serving as well as a support for manufacturers in decision making process involving the use of these technologies.This research has received funding from the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation programme (Grant Agreement No. 826312) in the context of the LightMe project. It has also received funds from Board of Education of Junta de Castilla y León and the European Social Fund (EDU/1508/2020).

    La parálisis cerebral infantil (PCI) es una de las principales discapacidades más comunes en el desarrollo infantil. Primera causa de discapacidad física importante en la infancia. La manifestaciones clínicas de esta enfermedad dependerán de la extensión y la localización de la lesión cerebral, así como de la capacidad del cerebro para adaptarse a ella. La PCI se clasifica en función de las manifestaciones clínicas del trastorno motor, las estructuras cerebrales comprometidas, el periodo en el cual se producen las lesiones y la gravedad de tipo de PCI. El abordaje de estos niños a menudo requiere de atención por un equipo multidisciplinar ya que estos niños tienen necesidades de atención médica compleja.Cerebral palsy (CPI) is one of the most common major disabilities in child development. It causes significant physical disability in childhood. The clinical manifestations of this disease will depend on the extent and location of the brain injury, as well as the ability of the brain to adapt to it. PCI is classified according to the clinical manifestations of the motor disorder, the brain structures involved, the period in which the injuries occur, and the severity of the type of PCI. The approach of these children often requires attention by a multidisciplinary team since these children have complex medical care needs.La paralisi cerebrale infantile (PCI) è una delle disabilità maggiori più comuni nello sviluppo del bambino. È la principale causa di disabilità fisica nell'infanzia. In questo capitolo abbiamo esaminato le manifestazioni cliniche di questa malattia che dipendono dall'estensione e dalla localizzazione della lesione cerebrale, nonché dalla capacità di adattamento del cervello. La classificazione è stata rivista in base alle manifestazioni cliniche del disturbo motorio, alle strutture cerebrali coinvolte e ai problemi associati a questa patologia infantile.Dječja cerebralna paraliza (DCP) jedan je od najčešćih teških poremećaja u razvoju djeteta.

    Targets, Mechanisms and Cytotoxicity of Half-Sandwich Ir(III) Complexes Are Modulated by Structural Modifications on the Benzazole Ancillary Ligand

    Cancers are driven by multiple genetic mutations but evolve to evade treatments targeting specific mutations. Nonetheless, cancers cannot evade a treatment that targets mitochondria, which are essential for tumor progression. Iridium complexes have shown anticancer properties, but they lack specificity for their intracellular targets, leading to undesirable side effects. Herein we present a systematic study on structure-activity relationships of eight arylbenzazole-based Iridium(III) complexes of type [IrCl(Cp*)], that have revealed the role of each atom of the ancillary ligand in the physical chemistry properties, cytotoxicity and mechanism of biological action. Neutral complexes, especially those bearing phenylbenzimidazole (HL1 and HL2), restrict the binding to DNA and albumin. One of them, complex 1[C,NH-Cl], is the most selective one, does not bind DNA, targets exclusively the mitochondria, disturbs the mitochondria membrane permeability inducing proton leak and increases ROS levels, triggering the molecular machinery of regulated cell death. In mice with orthotopic lung tumors, the administration of complex 1[C,NH-Cl] reduced the tumor burden. Cancers are more vulnerable than normal tissues to a treatment that harnesses mitochondrial dysfunction. Thus, complex 1[C,NH-Cl] characterization opens the way to the development of new compounds to exploit this vulnerabilityWe acknowledge the “la Caixa” Foundation (LCF/PR/PR12/11070003), Ministerio de Ciencia Innovación y Universidades-FEDER (RTI2018-102040-B-100) and Junta de Castilla y León-FEDER (BU305P18) for financial support.

    Electrodeposition of Molybdenum Disulfide (MoS2) Nanoparticles on Monocrystalline Silicon

    Get PDF
    Molybdenum disulfide (MoS2 ) has attracted great attention for its unique chemical and physical properties. The applications of this transition metal dichalcogenide (TMDC) range from supercapacitors to dye-sensitized solar cells, Li-ion batteries and catalysis. This work opens new routes toward the use of electrodeposition as an easy, scalable and cost-effective technique to perform the coupling of Si with molybdenum disulfide. MoS2 deposits were obtained on n-Si (100) electrodes by electrochemical deposition protocols working at room temperature and pressure, as opposed to the traditional vacuum-based techniques. The samples were characterized by X-ray Photoelectron Spectroscopy (XPS), Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM) and Rutherford Back Scattering (RBS)

    Antimicrobial Effect of Simira ecuadorensis Extracts and Their Impact on Improving Shelf Life in Chicken and Fish Products

    The objective of this work was to evaluate the antimicrobial potential of different extracts of Simira ecuadorensis, a characteristic plant of Ecuador, and to validate its potential as a food preservative. Four extracts referred to as ethanol, ethanol-water (50:50 v/v), spray-dried, and freeze-dried were obtained under different processes. Initially, their antimicrobial activities were evaluated against a wide group of microorganisms consisting of 20 pathogenic and spoilage microbial strains found in foods through the agar diffusion method. Then, the extracts with the best yields and antimicrobial properties against microorganisms of greatest interest were selected to determine their effect on model foods preserved under normal commercial conditions through challenge tests. Spray-dried and ethanol-water extracts were tested for their ability to inhibit C. jejuni in chicken model products, where is a common pathogen and Shew. putrefaciens in fish model products as it is a spoilage microorganism frequently found in fish. One solid and one liquid were chosen as model foods: burger and broth, respectively. Campylobacter jejuni and Shewanella putrefaciens were effectively inhibited by the four extracts with minimum inhibitory concentration (MIC) of 80 mg/mL. Bacillus cereus, Yersinia enterocolitica, Clostridium perfringens, and Leuconostoc mesenteroides were also inhibited by ethanolic extract. The ethanol-water extract showed greater antimicrobial activity in fish products, whereas spray-dried extract had low growth inhibition of C. jejuni in chicken burgers; however, it was quite effective on C. jejuni in broth. The spray-dried extract significantly decreased the pH of the chicken burgers, while the ethanolic extract had a slight impact on the pH of the fish burgers. The presence of antibacterial effects revealed that the S. ecuadorensis extracts could be potentially used in food preservation and as a natural antimicrobial
