    [ES] El presente Trabajo Final de Máster aborda el diseño y cálculo de la estructura, instalación eléctrica e instalación de protección contra incendios de una nave industrial destinada principalmente al almacenamiento y expedición de harina, ubicada en el término municipal de Silla (Valencia). Se trata de una nave de 50 metros de longitud por 20 metros de ancho, resuelta con estructura metálica a base de pórticos a dos aguas, de 1.140 metros cuadrados de superficie, con un altillo dos alturas destinado a oficinas y otros servicios. Se ha dispuesto también una marquesina lateral de 390 metros cuadrados. La instalación eléctrica se ha diseñado para abastecer las necesidades eléctricas del establecimiento, tanto para el alumbrado como para las tomas de corriente y maquinaria existentes. Se han diseñado las medidas de protección contra incendios, contemplando la instalación de exutorios, bocas de incendio equipadas, sistema de detección automática y extintores. Se dispondrá de un depósito y grupo de presión para el abastecimiento del agua para las bocas de incendio.[EN] The present Master Thesis deals with the design and calculation of the structure, electrical installation and fire protection installation of an industrial warehouse destined mainly for the storage and dispatch of flour, located in Silla (Valencia). It consists of an industrial building of 50 meters long by 20 meters wide, solved by a steel structure with gable frames, with a total 1.140 square meters floor area, comprising a twostorey mezzanine for housing the offices and other services. It has also a side canopy of 390 square meters. The electrical installation is designed to supply the electrical power needs of the industrial building, both for lighting and for existing electrical outlets and machinery. The fire protection measures have also been designed, including the installation of mechanical smoke vents, fire hose reels, automatic detection system and fire extinguishers. Additionally, a tank and pump unit will be installed, in order to supply the water for the fire hose reels.Cazorla García, C. (2020).

    The aim of this work is to establish the Oxygen Reduction Reaction (ORR) activity of self-standing electrospun carbon fiber catalysts obtained from different metallic salt/lignin solutions. Through a single-step electrospinning technique, freestanding carbon fiber (CF) electrodes embedded with various metal nanoparticles (Co, Fe, Pt, and Pd), with 8–16 wt% loadings, were prepared using organosolv lignin as the initial material. These fibers were formed from a solution of lignin and ethanol, into which the metallic salt precursors were introduced, without additives or the use of toxic reagents. The resulting non-woven cloths were thermostabilized in air and then carbonized at 900 °C. The presence of metals led to varying degrees of porosity development during carbonization, improving the accessibility of the electrolyte to active sites. The obtained Pt and Pd metal-loaded carbon fibers showed high nanoparticle dispersion. The performance of the electrocatalyst for the oxygen reduction reaction was assessed in alkaline and acidic electrolytes and compared to establish which metals were the most suitable for producing carbon fibers with the highest electrocatalytic activity. In accordance with their superior dispersion and balanced pore size distribution, the carbon fibers loaded with 8 wt% palladium showed the best ORR activity, with onset potentials of 0.97 and 0.95 V in alkaline and acid media, respectively. In addition, this electrocatalyst exhibits good stability and selectivity for the four-electron energy pathway while using lower metal loadings compared to commercial catalysts.The authors would like to thank the PID2019-105923RB-I00 project funded by MCIN/AEI/10.13039/501100011033, the RTI2018-097555-B-I00 project funded by MICINN and EFRD, and the Generalitat Valenciana (GRISOLIA/2020/114) for the financial support

    Cerebrospinal fluid neopterin as a biomarker of neuroinflammatory diseases.

    The elevation of neopterin in cerebrospinal fuid (CSF) has been reported in several neuroinfammatory disorders. However, it is not expected that neopterin alone can discriminate among diferent neuroinfammatory etiologies. We conducted an observational retrospective and case-control study to analyze the CSF biomarkers neopterin, total proteins, and leukocytes in a large cohort of pediatric patients with neuroinfammatory disorders. CSF samples from 277 subjects were included and classifed into four groups: Viral meningoencephalitis, bacterial meningitis, acquired immunemediated disorders, and patients with no-immune diseases (control group). CSF neopterin was analyzed with high-performance liquid chromatography. Microbiological diagnosis included bacterial CSF cultures and several specifc real-time polymerase chain reactions. Molecular testing for multiple respiratory pathogens was also included. Antibodies against neuronal and glial proteins were tested. Canonical discriminant analysis of the three biomarkers was conducted to establish the best discriminant functions for the classifcation of the diferent clinical groups. Model validation was done by biomarker analyses in a new cohort of 95 pediatric patients. CSF neopterin displayed the highest values in the viral and bacterial infection groups. By applying canonical discriminant analysis, it was possible to classify the patients into the diferent groups. Validation analyses displayed good results for neuropediatric patients with no-immune diseases and for viral meningitis patients, followed by the other groups. This study provides initial evidence of a more efcient approach to promote the timely classifcation of patients with viral and bacterial infections and acquired autoimmune disorders. Through canonical equations, we have validated a new tool that aids in the early and diferential diagnosis of these neuroinfammatory conditions
