Contact improvisation: una exploración del estilo de danza desde las aportaciones somáticas del aikido, el tuishou y el kinomichi
No full textPrograma de doctorado en Ciencias del deporteContact Improvisation es una forma de danza fundada por Steve Paxton en 1972, influenciado a través del Aikido y el Taijiquan, entre otras modalidades. Ha sido desarrollado principalmente en Nueva York, donde se establecieron maestros como Yoshimitsu Yamada y Zheng Manqing. También destacamos al coreógrafo canadiense Mark Young, quien ha incorporado el Tuishou, Taijiquan en parejas, en las últimas dos décadas. En Norteamérica, esta danza en parejas ha crecido académica y culturalmente, mientras que en Europa su práctica ha ocultado los orígenes de dichas influencias. Esta Tesis Doctoral tiene como finalidad determinar las contribuciones somáticas del Aikido, Tuishou y Kinomichi transferibles al ámbito de la salud del Contact Improvisation. Se ha utilizado una metodología de análisis para un estudio de caso de neurorrehabilitación a través del Contact Improvisation. A partir de este estudio, se han realizado revisiones de alcance (Scoping Review) y revisiones sistemáticas mediante el modelo PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) para acercarnos a esta finalidad. La exploración ha proporcionado una serie de factores comunes terapéuticos y rehabilitadores entre las artes marciales modernas y el Contact Improvisation. Con base a este análisis, se han determinado aspectos psicoterapéuticos del Aikido y se han descrito los campos de aplicación del Tuishou. Además, se ha encontrado el Kinomichi como un arte de origen marcial que visibiliza las bondades terapéuticas del Aikido. La conclusión de este estudio nos revela que en las contribuciones somáticas aportadas al Contact Improvisation subyace un aspecto en común denominado "neuromuscular repatterning".Contact Improvisation is a dance form founded by Steve Paxton in 1972, influenced by Aikido and Taijiquan. It has developed mainly in New York, where masters such as Yoshimitsu Yamada and Zheng Manqing have established themselves. We also highlight the Canadian choreographer Mark Young, who has incorporated Tuishou, Taijiquan in pairs, over the last two decades. In North America, this couple dance has grown academically and culturally, while in Europe its practice has obscured the origins of these influences. This dissertation aims to identify the somatic contributions of Aikido, Tuishou and Kinomichi that are transferable to the health field of Contact Improvisation. An analytical methodology was used for a case study of neurorehabilitation through Contact Improvisation. From this study, scoping reviews and systematic reviews were conducted using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) model to approach this goal. The review identified a number of common therapeutic and rehabilitative factors between modern martial arts and contact improvisation. Based on this analysis, the psychotherapeutic aspects of Aikido were identified and the areas of application of Tuishou were described. Furthermore, Kinomichi was found to be an art of martial origin that makes the therapeutic benefits of Aikido visible. The conclusion of this study shows that the somatic contributions to Contact Improvisation have a common aspect referred to as 'neuromuscular repatterning'

The atrioventricular conduction axis in man and mouse
No full textThose using the mouse for the purposes of electrophysiological research presume that the morphology of the conduction axis is comparable with the human arrangement. As yet, however, to the best of our knowledge, no direct comparison has been made between the species. By comparing our extensive histological findings in the human heart with comparable serially-sectioned datasets prepared from adult murine hearts, we aimed to provide this information. When comparing the gross anatomy, we used three-dimensional datasets of neonatal mice hearts prepared using episcopic microscopy. The overall cardiac architecture is comparable, although the mouse has a persistent left superior caval vein draining via the coronary sinus. An inferior pyramidal space and an infero-septal recess are both present in the murine heart, although they are not as well developed as in the human heart. The overall arrangement of the conduction axis is similarly comparable, albeit with subtle differences reflecting the incomplete wedging of the subaortic outflow tract in the murine heart. Most significantly, the findings in both species reveal the presence of extensive superior septal pathways, which perhaps explain the finding of base-to-apex activation of the ventricular mass known to occur in the murine heart.peerReviewe
Football and indoctrination: The cases of Austria, Germany, and Italy, 1920-1942. An example of sports barbarity
No full textEn un mundo despedazado por las contradicciones de clases, estados y nacionalidades, el fútbol, funcionó como una eficaz ideología de justificación del orden existente en un ambiente dominado por las teorías del darwinismo social y por las corrientes neomalthusianas, que defendían la desigualdad entre los hombres. Una época donde se vinculó la práctica futbolística a unas medidas bio-políticas orientadas a combatir los factores disgénicos, fue un modelo a seguir por el nacionalsocialismo y el fascismo. El fútbol, se convirtió en un escenario propicio para la afirmación de las identidades colectivas, de los antagonismos locales y regionales estableciéndose una relación metafórica entre estados nación y fútbol.
En cuanto al método empleado en el trabajo utilizaremos preferentemente el análisis de fuentes primarias, la hemerografía de la época y el análisis de revistas científicas de índole deportiva. La investigación la desarrollaremos partiendo de la heurística histórica y textual, aunando la metodología léxica deportiva a partir de la hermenéutica.
En nuestras conclusiones resaltaremos las consecuencias de la utilización ideológica del fútbol acaecido durante este periodo, el proceso de adoctrinamiento, la censura y represión ejercida sobre futbolistas, clubs y directivos en aras a perpetuar unos sistemas políticos totalitarios.In a World torn apart by the contradictions of classes, states and nationalities football functioned as and effective ideology of justification of the existing order in an environment dominated by the theories of social Darwinism and neo-Malthusian currents which defended inequality between men. A time when football practice was linked to bio political measures aimed at combating dysgenics factors, was a model to follow for national socialism. Football became a favourable scenario for the affirmation of collective identities of local and regional antagonisms establishing a metaphorical relationship between nation states and football.
Regarding the method used in the work we will preferably use to analysis of primary sources newspapers of the time and the analysis of scientific journals.
In our conclusions we will highlight the consequences of the ideological use of football occurred during this period, the indoctrination process, censorship and repression exerted of footballers, clubs and managers.peerReviewe
Pasture quality assessment through NDVI obtained by remote sensing: a validation study in the mediterranean silvo-pastoral ecosystem
No full textMonitoring the evolution of pasture availability and quality throughout the growing season is the basis of grazing management in extensive Mediterranean livestock systems. Remote sensing (RS) is an innovative tool that, among many other applications, is being developed for detailed spatial and temporal pasture quality assessment. The aim of the present study is to evaluate the potential of satellite images (Sentinel-2) to assess indicators of pasture quality (pasture moisture content, PMC, crude protein, CP and neutral detergent fiber, NDF) using the normalized difference vegetation index (NDVI). Field measurements were conducted over three years at eight representative fields of the biodiversity and variability of dryland pastures in Portugal. A total of 656 georeferenced pasture samples were collected and processed in the laboratory. The results show a significant correlation between pasture quality parameters (PMC, CP and NDF) obtained in standard laboratory methods and NDVI satellite-derived data (R2 of 0.72, 0.75, and 0.50, respectively). The promising findings obtained in this large-scale validation study (three years and eight fields) encourage further research (i) to test and develop other vegetation indexes for monitoring pasture nutritive value; (ii) to extend this research to pastures of the other Mediterranean countries, building large and representative datasets and developing more robust and accurate monitoring models based on freely available Sentinel-2 images; (iii) to implement an extension program for agricultural managers to popularize the use of these technological tools as the basis of grazing and pasture management.This work was funded by National Funds through FCT (Foundation for Science and Technology) under the Project UIDB/05183/2020.

Análise das diferentes voltas vencedoras no padel profissional: masculino vs. fêmea
No full textEl padel es uno de los deportes con más en auge en la actualidad, sin embargo, son necesarios más documentos que analicen los indicadores de rendimiento en competiciones de máximo nivel. El objetivo general de esta investigación fue analizar los indicadores de rendimiento en competiciones de máximo nivel en función del sexo. La muestra estuvo constituida por doce partidos (seis masculinos y seis femeninos) de las rondas finales de diferentes torneos del World Padel Tour en 2021, con un total de 1451 puntos analizados. Se registraron variables relacionadas con la consecución del punto (Tipo de golpe ganador, Tipo de remate, Dirección del remate, Jugador, Zona del campo) y con la dinámica del juego (Número de golpes, Consecución del punto). Los resultados mostraron diferencias entre los partidos masculinos y femeninos realizando comparativas porcentuales, pudiendo observar como en los encuentros femeninos la variedad para conseguir puntos es mucho mayor que en los partidos masculinos. Aunque en ambas modalidades estar cerca de la red es determinante, destacando el remate, sobre todo en la competición masculino, y las voleas, de derecha y revés, como golpes más utilizados para la consecución de los mismos. El saque aportará una ventaja significativa respecto al resto debido a que se colocarán cerca de la red.Padel is one of the most booming sports today, however, more documents are needed to analyze the performance indicators in top-level competitions. The general objective of this research was to analyze the performance indicators in top-level competitions according to sex. The sample consisted of twelve matches (six men's and six women's) from the final rounds of different World Padel Tour tournaments in 2021, with a total of 1451 number of points. Variables related to the achievement of the point (Type of winning shot, Type of shot, Direction of the shot, Player, Area of the field) and to the dynamics of the game (Number of shots, Achievement of the point) were recorded. The results showed differences between the men's and women's matches, making percentage comparisons of the duration of the point and obtaining them, being able to observe how the game is slower in the women's matches and the variety of getting points is much greater than in the men's matches. Although in both modalities being close to the net is decisive, highlighting the shot, especially in the men's competitions, and the volleys, forehand and backhand, as the most used shots to achieve them. The serve will provide a significant advantage over the rest because they will be placed near the net.peerReviewe
Biocontrol de ocratoxina A en jamón curado utilizando cultivos protectores combinados
No full textPrograma de Doctorado en Ciencia de los AlimentosLas condiciones ambientales alcanzadas durante la maduración de los derivados cárnicos curadomadurados favorecen el desarrollo de mohos productores de ocratoxina A (OTA) en su superficie como Penicillium nordicum y Aspergillus westerdijkiae. Una estrategia para controlar este peligro es la utilización de microorganismos autóctonos como agentes de biocontrol. El objetivo de la Tesis Doctoral fue diseñar métodos de biocontrol con cultivos protectores combinados para reducir la OTA en jamón curado. Primero, se comprobó que el uso combinado de P. chrysogenum 20922 y D. hansenii 253H reducía la producción de OTA por P. nordicum en jamón, pero no la suprimía totalmente. Posteriormente, se seleccionó S. xylosus Sx8 por su actividad antifúngica y se demostró que su acción se debe a la competencia por nutrientes y espacio, originando cambios en el proteoma de los mohos ocratoxigénicos. Durante la maduración de salchichones, se comprobó que D. hansenii 253H inoculada individualmente o en combinación con S. xylosus Sx8 era eficaz para reducir la producción de OTA por P. nordicum. Su combinación también fue efectiva para reducir esta micotoxina en jamón curado, originando cambios en el metaboloma de mohos ocratoxigénicos. Por último, se observó que el cultivo combinado con D. hansenii 253H, S. xylosus Sx8 y P. chrysogenum Pg222 provocó un descenso superior al 98 % de la producción de OTA por P. nordicum y redujo su concentración hasta valores no cuantificables en A. westerdijkiae en jamón curado, por lo que se pueden proponer como cultivo protector mixto para este alimento.The environmental conditions reached during the maturation of cured and matured meat products favour the development of ochratoxin A (OTA) producing moulds on their surface such as Penicillium nordicum and Aspergillus westerdijkiae. One strategy to control this hazard is the use of autochthonous microorganisms as biocontrol agents. The aim of the Doctoral Thesis was to design biocontrol methods with combined protective cultures to reduce OTA in dry-cured ham. First, the combined use of P. chrysogenum 20922 and D. hansenii 253H was shown to reduce OTA production by P. nordicum in dry-cured ham but did not completely
suppress it. Subsequently, S. xylosus Sx8 was selected for its antifungal activity and its action was found to be due to competition for nutrients and space, leading to changes in the proteome of ochratoxigenic moulds. During the maturation of dry-cured fermented sausages, D. hansenii 253H inoculated singly or in combination with S. xylosus Sx8 was found to be effective in reducing OTA production by P. nordicum. Their combination was also effective in reducing this mycotoxin in dry-cured ham, leading to changes in the metabolome
of ochratoxigenic moulds. Finally, it was observed that the combined culture with D. hansenii 253H, S. xylosus Sx8 and P. chrysogenum Pg222 was the most effective, causing a decrease of more than 98 % of the production of this mycotoxin by P. nordicum and reducing its concentration to unquantifiable values in A. westerdijkiae in dry-cured ham, so that they can be proposed as a mixed protective culture for this food.Ministerio de Industria, Economía y Competitividad (AGL2016-80209-P), al Ministerio de Ciencia e Innovación (PID2019-104260GB-I00) y a la Junta de Extremadura y al FEDER a través de la ayuda a Grupo GR18056 y GR21130
Thermal and Hydrodynamic Measurements of a Novel Chaotic Micromixer to Enhance Mixing Performance
No full textIn this study, three-dimensional simulations were conducted on a new passive micromixer to assess the thermal and hydrodynamic behaviors of Newtonian and non-Newtonian fluids subjected to low generalized Reynolds numbers (0.1 to 50) and shear-thinning properties. To acquire a more profound comprehension of the qualitative and quantitative fluctuations in fluid fraction using the CFD Fluent Code, the mass mixing index, rheological behavior, performance index, mixing energy cost, mass fraction distributions, temperature contours, and pressure drop were compared to illustrate the importance of the mixer geometry in the context of two miscible fluids with varying inlet temperatures. The selected geometry is characterized by a robust chaotic flow that substantially enhances thermal and hydrodynamic performance across all Reynolds numbers. A mass mixing exceeding 72.5% is obtained when Re = 5, reaching 93.5% when Re = 50. Furthermore, the evolution of thermal mixing for all behavior indexes reaches a step of 98% with minimal pressure losses. This work enabled the demonstration of a chaotic geometry in a highly efficient mixing system, leading to enhanced thermal performance for both Newtonian and non-Newtonian fluids. The results of the hydrodynamic and thermal characterization of the mixing of shear-thinning fluids within the micromixers under investigation are conclusive.n este estudio, se realizaron simulaciones tridimensionales en un nuevo micromezclador pasivo para evaluar los comportamientos térmicos e hidrodinámicos de fluidos newtonianos y no newtonianos sometidos a bajos números de Reynolds generalizados (0,1 a 50) y propiedades de adelgazamiento por cizallamiento. Para adquirir una comprensión más profunda de las fluctuaciones cualitativas y cuantitativas en la fracción de fluido utilizando el código fluido CFD, se compararon el índice de mezcla de masa, el comportamiento reológico, el índice de rendimiento, el costo de energía de mezcla, las distribuciones de fracciones de masa, los contornos de temperatura y la caída de presión para ilustrar la importancia de la geometría del mezclador en el contexto de dos fluidos miscibles con temperaturas de entrada variables. La geometría seleccionada se caracteriza por un flujo caótico robusto que mejora sustancialmente el rendimiento térmico e hidrodinámico en todos los números de Reynolds. Se obtiene una mezcla de masa superior al 72,5% cuando Re = 5, alcanzando el 93,5% cuando Re = 50. Además, la evolución de la mezcla térmica para todos los índices de comportamiento alcanza un escalón del 98% con pérdidas de presión mínimas. Este trabajo permitió la demostración de una geometría caótica en un sistema de mezcla altamente eficiente, lo que condujo a un mejor rendimiento térmico para fluidos newtonianos y no newtonianos. Los resultados de la caracterización hidrodinámica y térmica de la mezcla de fluidos de cizallamiento-raleo dentro de los micromezcladores bajo investigación son concluyentespeerReviewe
Estudio del comportamiento de perfiles metálicos de pared delgada y sección abierta como cimentación de plantas fotovoltaicas en terrenos cohesivos
No full textPrograma de Doctorado Ingeniería Industriales
Tesis por compendio de publicacionesEn esta investigación, se ha estudiado exhaustivamente el comportamiento flexotorsional de perfiles metálicos de paredes delgadas y sección abierta empleados como cimentaciones semiprofundas (pilotes), así como su interacción con suelos cohesivos sometidos a cargas laterales y torsionales. Los estudios experimentales y numéricos presentados han permitido desarrollar una comprensión integral sobre cómo estas cimentaciones responden a las cargas inducidas por el viento, y cómo su capacidad para disipar esfuerzos se ve afectada por su geometría, sección transversal y la interacción con el suelo.This research has extensively investigated the flexural behaviour of thin-walled, open-section metal sections used as semi-deep foundations (piles) and their interaction with cohesive soils subjected to lateral and torsional loads. The experimental and numerical studies presented have developed a comprehensive understanding of how these foundations respond to wind-induced loads and how their ability to dissipate stresses is affected by their geometry, cross-section and interaction with the soil
