Texte intégralThis dissertation examines how medical progresses, allowing for the cure of particularly diseases,and technological progress, such as the discovery of modern electric batteries, affect socio-economicdevelopment in the USA and in Sub-Saharan Africa. The dissertation also combines agriculturalprogresses, such as the discovery of a new staple crop with low health conditions, such as malariaprevalence to assess how much of the progress might be absorbed by poor environmental and healthconditions.The first chapter of the dissertation examines technological progresses, such as the creation ofmodern lithium-ion electrical batteries and their implications for socio-economic development. I ex-amine the cobalt mining boom in the Democratic Republic of Congo, which occurred in 2007, andwas caused by the advent of modern smartphones, PCs, tablets, and electric vehicles had on childlabor, through reduced education attainment and subsequently on parental fertility choices. Thisis achieved first, by combining geo-referenced data on education attainment and wealth conditionsof individuals across different villages or towns with the location of all cobalt mine deposits in theDRC in a differences-in-differences strategy. The procedure compares education attainment later inlife of those individuals who, during their childhood, lived within 10 kilometers away from a cobaltmine deposit before and after the cobalt mining boom. Moreover, the first chapter of the thesisshows that the increase in child labor lowers the opportunity cost for parents of having an additionalchild, thus resulting in a higher fertility rate. Effects of cobalt mining on wealth conditions, later inlife are also quantified.The second chapter of the dissertation examines progresses in medical field, such as the eradica-tion of malaria and related vector-borne diseases and their implications for historical economic de-velopment. I examine the eradication of malaria which happened in the US during early 1900s. Thisis achieved by comparing agricultural productivity levels of highly malarious counties with those ofless malarious counties before and after the eradication of malaria in the US which was achieved as aresult of the understanding that malaria was transmitted by the bite of specific species of mosquitoesand in turn of newly discovered drugs, such as quinine first and chemical components such as the DDT later on. Using a difference-in-difference (DID) estimation comparing historical agriculturalproductivity levels between US counties that had climatic conditions more suitable for the trans-mission of malaria with counties that were less suitable for a stable transmission of the disease, Ipresent causal evidence on the effects of higher malaria prevalence on agricultural productivity andeconomic development. Finally, the third chapter of this dissertation builds on the seminal paper of Nunn and Qian(2011) to examine if the positive impacts of the discovery of a new staple crop in the Old World,such as potato, on population and urbanization were partially absorbed by exogenous poor healthconditions. The exogenous variations of weather conditions for the transmission of malaria allowfor the comparison between potato suitable areas which had more or less prevalence of malaria. Weemploy two different estimation strategies. The first estimation entirely relies on that adopted inNunn and Qian (2011). The second estimation procedure allows us to compare population andurbanization levels at a 0.5° latitude by 0.5° longitude level. We find that the presence of weatherconditions suitable for a stable transmission of malaria counteracted the significant benefits onpopulation and urbanization observed during the eighteenth and nineteenth centuries due to theintroduction of potato.

Texte intégralModern world dynamics in which competitivity is the key word has forced organizations to structure themselves in a way to elaborate Strategic Technology Plans which consider the creation of research and innovation projects in short, medium and long terms. In this context it is up to Technology Manager to administrate and allocate the organization\'s limited financial resources in initiatives which enable opportunities to introduce innovations in the market which could add value either in financial terms and or for sustainability and Company\'s image. In the past Technology Strategic Plans which were based on Innovation Managers and Top Administration experience and intuition have produced good results, but in dynamic and globally interconnected markets there is no margin for mistakes under the penalty to compromise business continuity. There is a need to use Methodologies which enable the Technology Manager to balance the risks and success possibilities when implementing Technology Innovation programs and this reflection impelled the author to establish the following objectives for this research: a) Identify and apply Technological and Forecast analysis methodologies using a range of tools like Morphological Analysis, Delphi Method, Decision Matrix and Technological Road mapping which could allow the elaboration of Technological Roadmap applied to a specific technological scope and that could serve as well as a work routine for other technology branches.; b) Show to the reader the lessons learned in this research\'s process (right points and mistakes) as well as recommendations for this techniques use and suggestions for future studies. A specific product from Magneti Marelli in which this research\'s author works as Innovation Manager has been chosen as a theme for this action researches, that is, the Strut. The abovementioned methodologies composition has generated a rich data bank. The methodology implementation over these data generated a Technological Roadmap aiming to reduce weight in Struts. The right points and mistakes observed during research process have been shown as well suggestions for future studies. This is considered a material with a great academic and managerial value since the developed methodology can be applied total or partially in any technology field.

Texte intégralLa pesca marina de captura silvestre ha proporcionado a los seres humanos alimentos, ingresos y una forma de vida durante siglos. Sin embargo, el último medio siglo ha sido testigo de una dramática intensificación de los impactos humanos en el océano, amenazando los beneficios proporcionados por la pesca en todo el mundo. Procesos como el progreso tecnológico, los cambios demográficos, la gestión marina, el cambio climático y la mecanización influirán en gran medida en las pesquerías futuras y en quienes viven de ellas, pero ¿en qué medida y con qué consecuencias? Esta tesis tiene como objetivo explorar y desenredar los impulsores antropogénicos de cambio a gran escala y multidecadales en la pesca mundial. Desarrollo nuevas formas de representar procesos humanos clave en un modelo macroecológico global de peces y pesquerías, y utilizo el modelo para simular el efecto de cambios progresivos y abruptos en factores socioeconómicos y climáticos clave. Siempre que es posible, me baso en la teoría existente, pero para comprender mejor los mecanismos de cambio en los pescadores, también recopilo y analizo nuevos datos. En el primer estudio, incluyo la regulación pesquera en el modelo y lo utilizo para mostrar que la sostenibilidad a largo plazo en las pesquerías globales depende de una carrera entre una gestión pesquera fortalecida y aumentos en la eficiencia de las capturas impulsados por la tecnología. Mis hallazgos también sugieren que esta carrera puede ocultar una erosión progresiva de la biomasa global de peces. El segundo estudio investiga cómo responde la pesquería mundial a un evento de enfriamiento climático catastrófico; una guerra nuclear. Encuentro que si bien el enfriamiento disminuye un poco las posibles capturas de peces del océano, la gestión de la pesca proactiva y preventiva con anticipación puede crear un suministro considerable de pescado para la proteína animal de emergencia. El tercer estudio reconstruye el empleo mundial histórico en la pesca. Sugiere que, a pesar de las grandes diferencias regionales, la fracción de la población humana mundial que trabaja como pescadores ha sido sorprendentemente estable y el aumento de la captura por pescador relativamente pequeño entre 1950 y 2015. En conjunto, los hallazgos de esta tesis proporcionan una nueva comprensión a macroescala de procesos en la pesca mundial que son importantes para la gestión estratégica a largo plazo de los recursos marinos. También trazan vías para futuras investigaciones sobre la respuesta de la pesquería mundial a crisis repentinas y sobre la evolución a largo plazo de sus dimensiones humanas.
Marine wild-capture fisheries have supplied humans with food, income and a way of life for centuries. However, the past half century has seen a dramatic intensification of human impacts on the ocean, threatening the benefits provided by fisheries worldwide. Processes like technological progress, demographic shifts, marine management, climate change and mechanization will greatly influence future fisheries and those who live off them – but to what extent and with what consequences? This thesis aims to explore and untangle large-scale and multidecadal anthropogenic drivers of change in the global fishery. I develop new ways of representing key human processes in a global macroecological fish and fisheries model, and use the model to simulate the effect of both progressive and abrupt changes in key socio-economic and climatic factors. Where possible, I draw on existing theory, but to better understand the mechanisms of change in fishers, I also assemble and analyze new data. In the first study, I include fisheries regulation in the model, and use it to show that long-term sustainability in global fisheries hinges on a race between strengthened fisheries management and technology-driven increases in catch efficiency. My findings also suggest that this race can hide a progressive erosion of the global fish biomass. The second study investigates how the global fishery responds to a catastrophic climatic cooling event; a nuclear war. I find that while cooling somewhat decreases the potential fish catches from the ocean, proactive and precautionary fisheries management ahead of time can create a considerable supply of fish for emergency animal protein. The third study reconstructs the historical global employment in fisheries. It suggests that despite great regional differences, the fraction of the global human population working as fishers has been surprisingly stable and the increase in catch per fisher relatively small between 1950 to 2015. Altogether, the findings in this thesis provide new macro-scale understanding of processes in the global fishery that are important for long-term, strategic management of marine resources. They also lay out avenues for further research on the global fishery’s response to sudden shocks and on the long-term evolution of its human dimensions.

We show that the regularity of the gravitational metric tensor cannot be lifted from C0;1 to C1;1 by any C1;1 coordinate transformation in a neighborhood of a point of shock wave interaction in General Relativity, without forcing the determinant of the metric tensor to vanish at the point of interaction. This is in contrast to Israel's Theorem [6] which states that such coordinate transformations always exist in a neighborhood of a point on a smooth single shock surface. The results thus imply that points of shock wave interaction represent a new kind of singularity in spacetime, singularities that make perfectly good sense physically, that can form from the evolution of smooth initial data, but at which the spacetime is not locally Minkowskian under any coordinate transformation. In particular, at such singularities, delta function sources in the second derivatives of the gravitational metric tensor exist in all coordinate systems, but due to cancelation, the curvature tensor remains uniformly bounded.

Texte intégralInterferometria é a principal técnica de metrologia aplicada em física de choque. Velocidades de detonação e de partícula, medidas com resolução nanométrica, proporcionam resultados precisos utilizados para o cálculo de parâmetros chave para a caracterização da onda de detonação de choque. Particle/Photon Doppler Velocimetry (PDV) é um interferómetro de fibra ótica mais económico e de fácil uso, em relação aos seus predecessores. É utilizado para aplicações de tanto baixa como alta velocidade. Este trabalho engloba um design de PDV para a Universidade de Coimbra. A configuração do PDV e a especificação dos seus componentes é definido e minuciosamente justificado. O design do PDV é baseado em requerimentos definidos pelas aplicações desejadas (soldadura por explosão, testes de aceleração de placas planas e cilíndricas para caracterização de explosivos) e pela investigação de outros PDV publicada. A técnica de análise de dados é discutida com o objetivo de obter a melhor relação resolução de velocidade e temporal e com a escolha mais apropriada de window function para o algoritmo de transformada de Fourier. A experiência prática é descrita, juntamente com o PDV utilizado e a sua calibração. Os anexos resumem o design PDV, considera as perdas óticas previstas em cada componente e proporcionam uma estimativa de custo para um PDV de dois canais para a mesma aplicação.O design de PDV é severamente afetado economicamente pelo osciloscópio. O tipo de fibre end é demasiado dependente em aspetos práticos das experiências desejadas para dar uma resposta final. O design mede velocidade até 4 km/s com resolução de nanossegundos. Este trabalho é composto como um guia para qualquer tipo de PDV de geração um, iniciando em um contexto geral de seleção de componentes até à especificação baseada nos nossos requisitos.Upshifted PDV e multiplexing PDV são recomendados como possíveis evoluções do sistema, coincidindo com o atual estado da arte.
Interferometry is the main metrology technique applied in shock physics. The detonation and particle velocities measured with nanosecond resolution provide accurate results used for the calculation of key parameters to characterise the detonation shock wave. Particle/Photon Doppler Velocimetry (PDV) is a more affordable, easier to operate fibre optics interferometer than its predecessors, used for both low and high velocity experiments. This work was comprised to propose a PDV design for the University of Coimbra. The configuration of the PDV and the specification of its components is defined and thoroughly justified. The PDV design is based on requirements defined by the intended applications (explosive welding, cylinder and flyer plate tests for explosives characterisation) and research published on other PDV systems. The data analysis technique is also discussed as to obtain the maximum time-velocity resolution trade-off and select the appropriate window function of the Fourier transform algorithm. The gained practical experience is described and the used PDV detailed, along with the laser calibration. Annexes summarise the PDV design, account for expected power losses of each component and provide an estimated budget for a two channel PDV for the same application.The PDV design is severely hindered economically by the oscilloscope. The type of fibre end is too dependent on practical aspects of the experiments to provide a final response. The PDV design is prepared to measure particle velocities up to 4 km/s accurately with nanosecond resolution. This work is written as a guide for any type of generation one PDV design, starting from the general selection process to indicating the specifications of each component for the previously established requirements.Upshifted PDV and multiplexing PDV are recommended as possible upgrades of the system, coinciding with current state of the art.

Texte intégralFactores como radiação, poluentes tóxicos ambientais, stress oxidativo e choque térmico (CT) são muitas vezes apontados como responsáveis pela apoptose em embriões de bovinos, podendo este ser um dos fatores da baixa fertilidade observada nos bovinos durante a época de verão. Desta forma o presente estudo foi elaborado no sentido de avaliar a capacidade de maturação in vitro de ovócitos, após terem sido submetidos a um CT durante 0 (controlo) 6, 12 18 e 24 horas de CT1=39,5 °C e CT2=40,5 °C, bem como a expressão genética dos genes responsáveis pela sua maturação: Cx43, CDH1, DNMT1, HSPA14 e dos genes de referência, GAPDH e SDHA. Para isso, os complexos cumulus-ovócitos (CCOs) (n= 1124) foram aspirados durante os meses de Inverno e submetidos, respetivamente ao CT1 e CT2. Passadas as 24h, os CCOs foram divididos em dois grupos no qual no primeiro foram registadas as taxas de maturação nuclear (TMN), após a fixação e coloração com aceto-orceina (3:1) e no segundo grupo foi analisada a expressão genética, tendo como genes alvo Cx43, CDH1, DNMT1, HSPA14 e como referência os genes de manutenção GAPDH e SDHA. A duração do stress térmico resultou numa diminuição significativa (p <0,05) nas TMN para os ovócitos submetidos ao CT1 quando comparados com os resultados de maturação obtidos para o grupo controlo, diminuindo de 86,4% ± 4,3 para 65,5 ± 0,7; 51,3 ± 0,9; 38,1 ± 1,9 e 36,3 ± 0,9 respetivamente para o CT1 de 6, 12, 18 e 24 h. Esta diminuição de maturação foi ainda mais acentuada para o CT2 em que os valores baixaram para 38,4 ± 16,9; 35,7 ± 7,5; 29,1 ± 3,3; 20,3 ± 7,1 respetivamente para 6, 12, 18 e 24 h de CT. Para a avaliação da expressão de genes, os resultados demonstraram uma tolerância do ovócito ao CT nas 6h, não foi observada nenhuma regulação do gene CDH1 a partir das 12h mas o gene DNMT1 observou-se uma regulação positiva, representando o efeito do CT no desenvolvimento do ovócito.
ABSTRACT: Factors such as radiation, environmental toxic pollutants, oxidative stress and thermal shock (CT) was many times pointed as responsible for apoptosis in bovine embryos, which may be one of the factors of low fertility observed in cattle during the summer season. Thus, the present study was designed to assess the maturation of oocytes in vitro capacity, having undergone one o'clock CT for 0 (control) 6, 12, 18 and 24 hours of CT1 = 39.5 ° C and CT2 = 40.5 ° C, as well as gene expression of genes responsible for maturation: Cx43, CDH1, DNMT1, HSPA14 and reference genes, GAPDH and SdhA. For this, the cumulus-oocyte complexes (COCs) (n = 1124) were aspirated during the winter months and submitted respectively to CT1 and CT2. After 24h, COCs were divided into two groups where the first nuclear maturation rates were recorded (TMN), after fixing and staining with aceto-orcein (3: 1) and the second group gene expression was analyzed, Cx43 gene targeting, CDH1, DNMT1, and HSPA14 reference to the housekeeping genes GAPDH and SdhA. The duration of heat stress resulted in a significant decrease (p <0.05) in TMN for oocytes undergoing CT1 compared with the maturation results obtained for the control group, decreasing from 86.4% ± 4.3 to 65, 5 ± 0.7; 51.3 ± 0.9; 38.1 ± 1.9 and 36.3 ± 0.9 respectively for CT1 6, 12, 18 and 24 h. This decrease in maturation was even more pronounced for the CT2 where values fell to 38.4 ± 16.9; 35.7 ± 7.5; 29.1 ± 3.3; 20.3 ± 7.1 respectively 6, 12, 18 and 24 h CT. For review of gene expression, the results demonstrated oocyte tolerance CT in 6h, observed no regulation CDH1 gene from 12pm but the DNMT1 gene are observed a positive control, representing the effect of CT development oocyte.
