    Treball Final de Grau de Podologia, Facultat de Medicina i Ciències de la Salut, Universitat de Barcelona, curs: 2016-2017, Tutor: J. Ignasi Beltrán RuizLas plantillas exteroceptivas son un tipo de tratamiento que, mediante pequeños estímulos, usa los captores de la planta del pie para provocar cambios a nivel postural. Estos cambios se realizan por un sofisticado sistema postural de carácter neurológico coordinado a nivel del sistema nervioso central en el cual intervienen numerosas estructuras y con implicaciones que quizá parecen ajenas entre sí a simple vista, como la relación de este sistema con el origen neuro-anatómico de las emociones, dando una idea de que quizá un estímulo en la planta del pie pueda condicionar la modulación de determinadas emociones. La idea de que las plantillas exteroceptivas influyan en nuestro estado anímico no es muy clara, ni tampoco fácil de imaginar, pero es para ello que se ha realizado este estudio de búsqueda bibliográfica. En total se han encontrado 32 artículos que, si bien ninguno habla directamente de la relación entre este tipo de plantillas y el sistema emocional, sí que hablan de la acción de las plantillas exteroceptivas sobre la postura y también de la relación de la postura con el estado anímico. Los resultados muestran que, a través de una interacción sobre la postura, las plantillas exteroceptivas podrían influir sobre las emociones, pero de una forma indirecta, aunque pueda tener una relación hipotética neuro-anatómica directa. Para acabar de discernir todas las posibles aplicaciones de las plantillas exteroceptivas, hacen falta más estudios tanto en el campo emocional como postural y la relación entre ambos

    The aim of this project is the virtual recreation of the aircraft Mil Mi-12 by using CATIA V5 r19, a helicopter whose production started in Russia in 1965, during the Cold War, with military purposes and an aircraft that achieved eight world records, four of which are still current. The first part of the project explains the background of its design, the reason why Russia decided to create such aircraft and some other secondary purposes. Knowing the main goals of the helicopter, there will be a short explanation regarding the design process of the aircraft, as well as the configuration of some preliminary prototypes and, after that, there will be introduced its main characteristics and technical specifications, in order to have a general knowledge about its final design. After that, in this same part, there will be mentioned the records achieved by the aircraft and some of the variants that, although some of them were never carried out, their production was in the mind of the engineers in charge of the project. Additionally, there will be commented everything related to its operational history. Once all the general knowledge about the aircraft has been provided, the following section will be dedicated to the main purpose of this project, the 3D modelling of the Mi-12. In order to do so, there will be an exhaustive explanation about each of the steps taken during the design process with CATIA. The order followed in this section will be the same carried out while modelling the aircraft, both externally and internally. Therefore, with each of the parts in which the Mi-12 has been divided during the design process completely defined, there will be explained the assembly process, which will provide the complete model of the aircraft. It is worth to mention that at the end of the project, there have been shown some rendered photographs of the created model in order to imagine how it would look in the actual world.Universidad de Sevilla.

    295 p.Las baterías de sodio ión están consideradas como una de las tecnologías más prometedoras como alternativa a las de litio ión usadas comúnmente a día de hoy. Especialmente, los óxidos laminares son uno de los candidatos más estudiados como material de cátodo. En este trabajo se estudian materiales ricos en hierro debido a su bajo coste y toxicidad, así como por sus interesantes propiedades electroquímicas: alta capacidad y voltaje. Sin embargo, a pesar de sus interesantes propiedades teóricas, estos materiales se deterioran con el ciclado.Esta tesis investiga estos mecanismos de degradación mediante el estudio de la evolución estructural utilizado difracción de rayos X y espectroscopía Mossbauer, así como la evolución del coeficiente de difusión mediante la impedancia electroquímica y la titulación potenciostática intermitente.Esta tesis ha confirma la migración de los iones de metal de transición a las capas de sodio, y se enseña por primera vez la migración en función del estado de carga. Sorprendentemente, se ha visto que la migración es más reversible de lo que se esperaba. En lugar de tratar de evitar la migración, el esfuerzo debería focalizarse en tratar de mejorar la reversibilidad de la actividad redox del oxígeno, ya que ambos eventos están relacionados.CIC Energigun

    El artículo describe el desarrollo y características de producción de aceros en Euskadi. El hierro se puede obtener de tres maneras: fundición, acero y hierro. El acero parece ser del 3000 a. de J.C., llegando a la península hacia el 650 a. de J.C. Una de las primeras ferrerías de la de las Peñas de Aya (Gipuzkoa). En el desarrollo de la siderometalurgia vasca hay dos etapas: la clásica con dos períodos diferentes (ferrerías de montaña y de ribera) y la modernaThe article describes the development and characteristics of the production of steel in the Basque Country. Iron could be obtained in three ways: smelting, steel and iron. Iron seems to date back to 3000 B.C., and it arrived in the Iberian peninsula towards 650 B.C. One of the first ironsmitheries was that in Peñas de Aya (Gipuzkoa). In the development of Basque siderurgy there are two stages: the classical one with two different periods (mountain and river bank smitheries) and modern ag

    EPJ Applied Physics 56. 2 (2011): 24021 with kind permission of The European Physical Journal (EPJ)A full characterization of plasma polymerized biofunctional films requires the use of multi-analytical approaches to determine the chemical composition, topography and potential interaction mechanisms of such films with biomolecules and cells. In this work we aim at underlining the versatility of ion-based techniques to contribute to the chemical characterization of plasma polymerized surfaces. The simultaneous use of energy recoil detection (ERD) and Rutherford backscattering (RBS) spectroscopies with incident He ions is an example of this versatility. Performing sequential measurements and the use of correlating computing tools for ERD-RBS interpretation allows providing in-depth concentration profiles of light elements, including namely hydrogen. More accurate analysis of light elements in polymer films can be increased by looking for particular ions with resonant backscattering responses (i.e., non-Rutherford Scattering). In particular, proton beams of 1.765 MeV are used to increase the detection of C and N, and particular incidence and detector angles to diminish the Si substrate contribution. These analytical tools have been applied to allylamine films and multi-layers crosslinked in a capacitive plasma onto both Si and porous Si substratesWe acknowledge MICINN funding provided by Grant No. MAT2008-06858-C02-01 and grant from Fundación Domingo Martíne

    Evidence-based management of multiple sclerosis spasticity with nabiximols oromucosal spray in clinical practice: a 10-year recap.

    Get PDF
    Effective symptomatic management of multiple sclerosis (MS) spasticity remains an unmet need for many patients. The second-line option nabiximols is the most widely investigated of the noninvasive antispasticity medications in this patient population. Clinical evidence accumulated with nabiximols since it was first approved in Europe in 2010 suggests that about 40% of initial responders (i.e., those with ≥20% improvement in their baseline 0-10 Numerical Rating Scale score) may expect to achieve clinically meaningful (≥30% Numerical Rating Scale response) and durable symptomatic improvement in MS spasticity. During 10 years' routine use of nabiximols, no new safety signals have emerged. Nabiximols-associated improvement in MS spasticity-related symptoms such as pain and sleep disruption suggests a need to track possible therapeutic effects beyond muscle tone control

    Visible light assisted organosilane assembly on mesoporous silicon films and particles

    Porous silicon (PSi) is a versatile matrix with tailorable surface reactivity, which allows the processing of a range of multifunctional films and particles. The biomedical applications of PSi often require a surface capping with organic functionalities. This work shows that visible light can be used to catalyze the assembly of organosilanes on the PSi, as demonstrated with two organosilanes: aminopropyl-triethoxy-silane and perfluorodecyl-triethoxy-silane. We studied the process related to PSi films (PSiFs), which were characterized by X-ray photoelectron spectroscopy (XPS), time of flight secondary ion mass spectroscopy (ToF-SIMS) and field emission scanning electron microscopy (FESEM) before and after a plasma patterning process. The analyses confirmed the surface oxidation and the anchorage of the organosilane backbone. We further highlighted the surface analytical potential of 13 C, 19 F and 29 Si solid-state NMR (SS-NMR) as compared to Fourier transformed infrared spectroscopy (FTIR) in the characterization of functionalized PSi particles (PSiPs). The reduced invasiveness of the organosilanization regarding the PSiPs morphology was confirmed using transmission electron microscopy (TEM) and FESEM. Relevantly, the results obtained on PSiPs complemented those obtained on PSiFs. SS-NMR suggests a number of siloxane bonds between the organosilane and the PSiPs, which does not reach levels of maximum heterogeneous condensation, while ToF-SIMS suggested a certain degree of organosilane polymerization. Additionally, differences among the carbons in the organic (non-hydrolyzable) functionalizing groups are identified, especially in the case of the perfluorodecyl group. The spectroscopic characterization was used to propose a mechanism for the visible light activation of the organosilane assembly, which is based on the initial photoactivated oxidation of the PSi matrixWe acknowledge MSC funding provided by the European Commission through FP7 grant THINFACE (ITN GA 607232) and by Ministerio de Economía y Competitividad through grant NANOPROST (RTC-2016-4776-1
