An understanding of sediment redox conditions across the Paleocene-Eocene thermal maximum (PETM) (?55 Ma) is essential for evaluating changes in processes that control deep-sea oxygenation, as well as identifying the mechanisms responsible for driving the benthic foraminifera extinction. Sites cored on the flanks of Walvis Ridge (Ocean Drilling Program Leg 208, Sites 1262, 1266, and 1263) allow us to examine changes in bottom and pore water redox conditions across a ~2 km depth transect of deep-sea sediments of PETM age recovered from the South Atlantic. Here we present measurements of the concentrations of redox-sensitive trace metals manganese (Mn) and uranium (U) in bulk sediment as proxies for redox chemistry at the sediment-water interface and below. All three Walvis Ridge sites exhibit bulk Mn enrichment factors (EF) ranging between 4 and 12 prior to the warming, values at crustal averages (Mn EF = 1) during the warming interval, and a return to pre-event values during the recovery period. U enrichment factors across the PETM remains at crustal averages (U EF = 1) at Site 1262 (deep) and Site 1266 (intermediate depth). U enrichment factors at Site 1263 (shallow) peaked at 5 immediately prior to the PETM and dropped to values near crustal averages during and after the event. All sites were lower in dissolved oxygen content during the PETM. Before and after the PETM, the deep and intermediate sites were oxygenated, while the shallow site was suboxic. Our geochemical results indicate that oxygen concentrations did indeed drop during the PETM but not sufficiently to cause massive extinction of benthic foraminifera.

En este trabajo se ha realizado un análisis de la estructura del juego y de los parámetros morfológicos y fisiológicos en jugadores de bádminton. Para ello se han realizado 4 estudios aplicados. Objetivo: Los objetivos del trabajo han sido: (1) comprobar si existen diferencias entre el lado dominante y no dominante de las medidas antropométricas en jugadores de bádminton de máximo nivel nacional, así como verificar si el lado del cuerpo donde se realiza la medición puede influir en el cálculo de la composición corporal y del somatotipo. (2) Comparar la estuctura temporal y notacional en partidos de individual masculino entre los Juegos Olímpicos de Pekín y de Londres para observar como ha evolucionado el bádminton de 2008 a 2012. (3) Medir la ocurrencia de daño muscular después de un partido simulado de bádminton y su influencia en parámetros físicos y hematológicos. (4) Investigar la efectividad de una bebida energética que contiene cafeína para mejorar el rendimiento físico y el rendimiento en un partido en jugadores de élite de bádminton. Metodología: Para caracterizar el bádminton participaron en esta tesis un total de 78 jugadores de bádminton de élite (63 hombres y 15 mujeres), distribuidos en tres estudios y se analizaron 40 sets de bádminton de individual masculino usando los videos oficiales de los Juegos Olímpicos de Pekín 2008 y Londres 2012. En el primer estudio se tomaron medidas de pliegues cutáneos, diámetros, longitudes y perímetros del lado dominante y no dominante de los jugadores. Se calculó la composición corporal y el somatotipo. En el segundo estudio se analizaron los factores temporales y los factores notacionales de los partidos. En el tercer estudio se midieron la fuerza máxima isométrica, la velocidad en test específicos de bádminton y se tomaron muestras de sangre antes y después de jugar un partido de bádminton de 45 minutos. En el cuarto estudio se realizó un experimento a doble ciego, aleatorizado y controlado con placebo, los jugadores ingirieron 3 mg de cafeína por kilógramo de masa corporal en forma de bebida energética, o la misma bebida sin cafeína (placebo). En este estudio se registraron diferente tests específicos de bádminton (tests de salto, fuerza máxima y test de agilidad) y se jugó un partido simulado de 45 minutos. Resultados y discusión: (1) El porcentaje óseo fue mayor calculado a partir de las mediciones del lado dominante (dominante = 16.37 ± 1.14 %, no dominante = 15.66 ± 1.12 %; P < 0.001), mientras que el porcentaje muscular fue mayor calculado a partir de las mediciones del lado no dominante (dominante = 49.39 ± 2.60 %, no dominante = 50.18 ± 2.69%; P < 0.001). (2) La duración del set (Pekín: 1124.6 ± 229.9 s vs Londres: 1260.3 ± 267.1 s.; P < 0.05), el tiempo real de juego (Pekín: 306.9 ± 45.7 s vs Londres: 354.7 ± 86.5 s; P < 0.05), tiempo de rally, golpeos por rally, tiempo de descanso en el punto 11, tiempo de descanso entre sets y golpeos por rally fueron significativamente mayores en Londres que en Pekín. (3) El partido simulado de bádminton no afectó a la fuerza isométrica máxima (Pre: 1263.6 ± 245.5, Post: 1290.8 ± 240.4 N) o a la velocidad específica de bádminton (Pre: 21.0 ± 1.7, Post: 20.9 ± 1.8 s), sin embargo las concentraciones de mioglobina y de creatina quinasa en sangre aumentaron de 26.5 ± 11.6 a 197.3 ± 70.2 μg • L-1 y de 258.6 ± 192.2 a 466.0 ± 296.5 U • L-1, respectivamente después del partido de bádminton. (4) En comparación con la bebida placebo, la ingesta de la bebida energética con cafeína incrementó la altura del SJ (34.5±4.7 vs. 36.4±4.3 cm; P < 0.05) y del CMJ (37.7 ± 4.5 vs. 39.5 ± 5.1 cm; P < 0.05) y aumentó el número de aceleraciones totales durante el partido (7395 ± 1594 vs. 7707 ± 2033 aceleraciones; P < 0.05). Conclusiones: (1) Existen asimetrías corporales en los jugadores de bádminton de alto nivel, al encontrarse diferencias en los diámetros óseos y en los perímetros entre el lado dominante y no dominante. Al calcular la composición corporal con el lado dominante de los jugadores de bádminton se está sobreestimando el porcentaje óseo e infraestimando el porcentaje muscular. (2) El bádminton está evolucionando hacía rallies más largos con intervalos de descanso mayores, lo que resulta en partidos más largos. (3) El partido de bádminton generó daño muscular, sin embargo, el nivel de daño muscular alcanzado después de un partido de bádminton no produjo una disminución del rendimiento muscular. (4) El uso de una bebida energética con cafeína puede ser una ayuda nutricional eficaz para aumentar el rendimiento en el salto y patrones de actividad durante el juego en jugadores de élite de bádminton. ABSTRACT: This study analyzes the structure of the game and the morphological and physiological parameters in badminton players, investigated in four applied studies. Purpose: The purposes of the study were: (1) To check if there are differences between the dominant and non-dominant side in the anthropometric measures of badminton players at the highest national level and verify if the side of the body where the measurements are performed can influence the calculation of the body composition and the somatotype. (2) To compare the temporal and notational structure in men’s singles matches between the Olympic Games in Beijing and London to observe the evolution of badminton between 2008 and 2012. (3) To asses the occurrence of muscle damage after a simulated badminton match and its influence on physical and haematological parameters. (4) To determine the effectiveness of a commercially available energy drink that contains caffeine to improve match performance in elite badminton players. Methods: A total of 78 elite badminton players (63 men and 15 women) participated in this thesis to characterize the sport of badminton distributed in three studies and 40 sets of men’s singles badminton analyzed using the official videos of the Olympic Games of Beijing 2008 and London 2012. In the first study skinfolds, diameters, lengths and perimeters of the dominant and non-dominant side of the players were measured and body composition and somatotype were calculated. In the second study the temporal and notational factors were analyzed. In the third study maximal isometric force and speed in badminton specific tests were measured and blood samples were taken before and after a badminton match of 45 minutes. In the fourth study, a double-blind, randomized placebo-controlled experiment, players ingested 3 mg of caffeine per kilogram of body mass in the form of an energy drink or an identical drink with no caffeine content (placebo). In this study different badminton specific tests (jump tests, handgrip force test and an agility test) were recorded and a simulated badminton match of 45 minutes was played. Results and discussion: (1) The percentage of bone was higher when calculated from measurements of the dominant body side (dominant = 16.37 ± 1.14 %, nondominant = 15.66 ± 1.12 %; P < 0.001), while the muscle percentage was higher when calculated from measurements of the non-dominant side (dominant = 49.39 ± 2.60 %, non-dominant = 50.18 ± 2.69%; P < 0.001). (2) Set duration (Beijing: 1124.6 ± 229.9 s vs. London: 1260.3 ± 267.1 s.; P < 0.05), real time played (Beijing: 306.9 ± 45.7 s vs. London: 354.7 ± 86.5 s; P < 0.05), rally time, shots per rally, rest time at point 11, rest time between sets and shots per rally were significantly higher in London than in Beijing. (3) A simulated badminton match did not affect maximal isometric force (Pre: 1263.6 ± 245.5, Post: 1290.8 ± 240.4 N) or specific badminton speed (Pre: 21.0 ± 1.7, Post: 20.9 ± 1.8 s), however, concentrations of myoglobin and creatine kinase in blood increased from 26.5 ± 11.6 to 197.3 ± 70.2 μg • L-1 and from 258.6 ± 192.2 to 466.0 ± 296.5 U • L-1, respectively after the badminton match. (4) In comparison to the placebo drink, the caffeinated beverage increased height in the SJ (34.5±4.7 vs. 36.4±4.3 cm; P < 0.05) and in the CMJ (37.7 ± 4.5 vs. 39.5 ± 5.1 cm; P < 0.05) and increased the number of total accelerations during the match (7395 ± 1594 vs. 7707 ± 2033 accelerations; P < 0.05). Conclusions: (1) Body asymmetries were found in high level badminton players, due to the differences found in bone diameters and perimeters between the dominant and non-dominant body side. When calculating body composition with the dominant side of the badminton players we are overestimating bone percentage and underestimating muscle percentage. (2) Badminton is evolving towards longer rallies with greater rest intervals, resulting in longer matches. (3) The badminton match generated muscle damage, however, the level of muscle damage reached after a badminton match did not produce a decrease in muscle performance. (4) The ingestion of an energy drink containing caffeine might be an effective ergogenic nutritional supplement to increase jump performance and activity patterns during the game in elite badminton players.

New technologies such as, the new Information and Communication Technology ICT, break new paths and redefines the way we understand business, the Cloud Computing is one of them. The on demand resource gathering and the per usage payment scheme are now commonplace, and allows companies to save on their ICT investments. Despite the importance of this issue, we still lack methodologies that help companies, to develop applications oriented for its exploitation in the Cloud. In this study we aim to fill this gap and propose a methodology for the development of ICT applications, which are directed towards a business model, and further outsourcing in the Cloud. In the former the Development of SOA applications, we take, as a baseline scenario, a business model from which to obtain a business process model. To this end, we use software engineering tools; and in the latter The Outsourcing we propose a guide that would facilitate uploading business models into the Cloud; to this end we describe a SOA governance model, which controls the SOA. Additionally we propose a Cloud government that integrates Service Level Agreements SLAs, plus SOA governance, and Cloud architecture. Finally we apply our methodology in an example illustrating our proposal. We believe that our proposal can be used as a guide/pattern for the development of business applications.

O aumento na demanda mundial por energia, a perspectiva de encolhimento dos recursos energéticos e a preocupação global com a questão ambiental, despertaram o interesse por fontes alternativas de energia. A biomassa lignocelulósica é abundante e de baixo custo, com potencial para complementar a produção em larga escala de combustíveis. A degradação das moléculas constituintes da parede celular à açúcares fermentescíveis e então à etanol, ocorre através da hidrólise enzimática da biomassa. Contudo, a utilização de enzimas para esse fim encontra-se em estágio exploratório e representa um gargalo na implementação de tecnologias de etanol 2G em escala industrial, desencadeando a busca de celulases bioquimicamente mais ativas, estáveis e economicamente viáveis. O presente trabalho visou a caracterização da endoglucanase I do fungo Trichoderma harzianum, e para isso foi realizada expressão, ensaios bioquímicos e biofísicos do domínio catalítico (ThCel7B-CCD) e da proteína inteira (ThCel7B-full). A enzima exibiu um perfil acidofílico, com atividade ótima em pH 3,0 a 55°C. A proteína também se mostrou capaz de hidrolisar uma variedade de substratos, sendo a maior atividade hidrolítica em β-glucano (75 U mg-1). Ao analisar a estabilidade térmica medida a 55°C em pH 5, a atividade residual manteve-se intacta por mais de 2 meses. Outra característica relevante foi o elevado grau de sinergismo entre ThCel7B e ThCel7A. Análises de microscopia eletrônica de flocos de aveia submetidas à hidrólise com ThCel7B evidenciaram os efeitos de degradação do substrato em relação às amostras controle. O conjunto desses resultados, além de importante para a compreensão do mecanismo molecular de ThCel7B e de outras endoglucanases da família GH7, também revelou uma enzima de interesse biotecnológicos uma vez que o comportamento ácido e sua estabilidade térmica são características relevantes para aplicações industriais sob condições extremamente ácidas.
