Estudio experimental de la respuesta espacio-temporal de ondas gravitacionales en un flujo afectado débilmente por la rotación del medioRojas Lizama, Pedro Antonio January 2015 (has links)
Ingeniero Civil / Los procesos físicos y bioquímicos de lagos estratificados están fuertemente relacionados con la dinámica de las ondas gravitacionales superficiales e internas, las cuales son excitadas principalmente por la acción del viento en la superficie libre. Dependiendo del tamaño y de la latitud del cuerpo lacustre, la estructura espacio-temporal del campo de ondas gravitacionales puede comenzar a ser afectada por la rotación terrestre, posibilitando la existencia de dos clases de ondas de gravedad de gran escala, conocidas ampliamente como ondas de Kelvin y ondas de Poincaré. La dinámica de éstas ondas puede verse alterada por fenómenos no-lineales, permitiendo la formación de ondas con características no-lineales, tales como las ondas tipo solitarias.
En el Laboratorio de Hidráulica Francisco J. Domínguez, ubicado en el Departamento de Ingeniería Civil de la Universidad de Chile, se cuenta con un estanque cilíndrico montado sobre una mesa rotatoria con capacidad de inclinación, al interior de una cámara oscura. Allí se llevó a cabo un estudio experimental, con el objetivo de analizar la respuesta espacio-temporal de ondas gravitacionales - superficiales e internas - en un flujo afectado débilmente por la rotación del medio. Para ello, se realizaron 54 experimentos barotrópicos de una capa, donde se varió tanto la rotación como la inclinación inicial del sistema, y 3 experimentos baroclínicos de dos capas, donde se varió la rotación del medio y se delimitó superiormente el flujo con una tapa rígida. El campo de ondas de gravedad es excitado mediante la liberación de una inclinación lineal (diametral) inicial de las interfaces agua-aire y de densidad, respectivamente. La condición inicial induce ondas del tipo Kelvin y Poincaré, en respuesta al gradiente de presión horizontal inicial y a la rotación del medio, excitando todos los modos radiales del sistema y el modo azimutal fundamental. La evolución temporal de la perturbación de las interfaces se ha registrado con un CCD a lo largo del plano diametral inicialmente forzado, mediante la utilización del método óptico de fluorescencia inducida por láser (LIF). Adicionalmente, para los experimentos barotrópicos, la evolución temporal de la perturbación interfacial se registró en el borde mediante un sensor tipo capacitivo. El acoplamiento de ambos métodos permite caracterizar espacialmente el campo de ondas de gravedad.
Resultados obtenidos del espectro de densidad potencial (PSD) y de la transformada de wavelet (WT) evidencian distintos comportamientos dinámicos del campo de ondas gravitacionales en función del espacio, la rotación y la perturbación inicial. Los resultados dan cuenta de una transferencia de energía, en el espectro gravitacional, desde los modos fundamentales de baja frecuencia, a sub-modos radiales y azimutales de alta frecuencia. La estructura de la cascada de energía está influenciada por la rotación y el régimen dinámico de las ondas de gran escala.

From the Lago's plan of action (LPA) to the new partnership for Africa's development(NEPAD): The political economy of African regional initiativesIkome, Francis Nguendi 21 February 2006 (has links)
PhD - International Relations / The thesis examines the design and implementation of African regional economic
cooperation initiatives using the Lagos Plan of Action (LPA) and the New Partnership for Africa’s Development (NEPAD) as comparative case studies. With regards to design, it focuses on the international political economy of the shift from the LPA’s state-led, inward-looking, collective self-reliance model to NEPAD’s outward looking, market-friendly orientations. Pertaining to implementation, it examines the
domestic political economy of institutionalising compliance with regionally agreed policy prescriptions in the absence of an overarching central authority. It focuses on the level of implementation of the LPA and the prospects of implementing NEPAD.
The thesis pursues two main sets of arguments: First, it argues that African states’ common concerns about their vulnerability in the global economy have informed the design of a number of ambitious regional initiatives. Within this context, the shift from the LPA to the NEPAD has been dictated by changes in global realities and
circumstances. Second, it argues that individual African governments’ concern with vulnerability nationally has been responsible for the low levels of implementation of regional economic initiatives. In this regard, the prospects for the sustained implementation of regional cooperation initiatives is structured by expectations of socio- economic benefits, the cost of compliance to states and the institutions to enforce compliance.
The study employs neo-liberal and nationalist perspectives of international political economy to explain how global realities have dictated Africa’s economic cooperation options. To explain African governments’ attitude towards regional initiatives, the thesis uses insights from comparative political economy. The thesis
meanwhile employs insights from institutional economics and rational choice institutionalism to highlight the difficulties of institutionalising compliance with regional policy prescriptions.
To capture the differences in the contexts within which the LPA and the NEPAD were crafted and the variations in their orientations, the thesis uses a combination of ‘historical explanation’ and ‘structured focused comparison’ methodology that allows for two separate, but structurally linked accounts of the processes of design and implementation of the two initiatives.

Previous issue date: 2014-03-18 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / A variedade de ecossistemas microbianos que existe na Antártica representa uma oportunidade extraordinária para pesquisas sobre a ecologia, diversidade e evolução microbiana, principamente em termos de cianobactéria. Neste trabalho, foi avaliado o papel de atributos ambientais no controle da montagem de esteiras microbianas antárticas. Inicialmente foi caracterizado a diversidade cianobacteriana das esteiras ao longo de gradientes ambientais na região do McMurdo Sound, Antártica continental. Em seguida, foi avaliado o papel das variáveis ambientais na determinação da composição da assembléia de cianobactérias através da análise de amostras de água e esteiras de cianobactérias microbianas de 25 lagos distribuídos em quatro distintas áreas geográficas: McMurdo Ice Shelf, Ross Island e Upper e Lower Wright Valleys. Finalmente, foi realizado experimentos de laboratório para determinar a extensão com que a composição de espécies afeta a formação das esteiras microbianas. Vinte e nove morfoespécies foram identificadas e descritas no capítulo 1. Quatro foram designadas à ordem Chroococcales, três Nostocales e 22 Oscillatoriales. No segundo capítulo foram investigados os fatores que podem estar envolvidos na determinação da presença e/ou ausência de cianobactérias dentro da comunidade das esteiras microbianas em cada lago amostrado. Os lagos das regiões Ross Island, McMurdo Ice Shelf e Upper e Lower Wright Vallyes apresentaram algumas características específicas próprias de cada área em termos de fatores físico-químicos e diversidade de cianobactérias, embora em vários casos houve uma sobreposição considerável das características. A análise multivariada dos dados, com base em variáveis físico-químicas mostrou que os lagos de cada área amostrada tendeu a se agruparem por local, embora com considerável sobreposição, com os dois Wright Valleys e as duas zonas costeiras tendendo a ser mais semelhantes entre si. Este padrão tendeu a ser reproduzido em análises dos dados de biomassa e composição das espécies, onde foi possível indentificar táxons que foram amplamente espalhados por toda a região e outros que foram mais restritos por área. A importância da dispersão e condições de crescimento na condução desse padrão foi discutida. No terceiro capítulo foi desenvolvido um experimento para avaliar o papel de cepas de cianobactérias isoladas no processo de formação de esteiras microbianas. Seis cepas de cianobactérias foram utilizadas, em combinações variadas, para formar biofilmes em condições de laboratório: CYN-50 (Phormidium cf. autumnale); CYN-68 (Leptolyngbya A); CYN-65 (Leptolyngbya B); CYN-66 (Microcoleus sp.); CYN-67 (cf. Aphanocapsa) e CYN- 72 (Nostoc sp.). O conteúdo de clorofila-a, exopolissacarídeo e matéria orgânica foi avaliado e utilizado como medida de avaliação do desenvolvimento dos biofilmes. No final do experimento, observou-se que os biofilmes desenvolvidos mostraram-se diferentes em termos de sua morfologia e que as cianobactérias filamentosas “oscilatoriales” são requeridas para a formação de biofilme consistente, entretanto, todas as cepas morfologicamente diferentes produziram efeito nas matrizes dos biofilmes. Phormidium produziu o melhor biofilme desenvolvido. Em conclusão, este trabalho fornece um maior conhecimento sobre a taxonomia e ecologia de cianobactérias da Antártica na região do McMurdo Sound. Nós identificamos uma mistura de organismos amplamente distribuídos e tolerantes e outros com distribuições mais locais e requerimentos ambientais específicos. A significância destes em temos de gestão da biodiversidade antártica também foi discutida.

SANTOS, Claudineia Lizieri dos, D.Sc., Universidade Federal de Viçosa, March of 2014. Environmental attributes in assembling cyanobacterial communities from the Mcmurdo Sound region, Antarctica. / The variety of microbial ecosystems that exist in Antarctica represents an extraordinary opportunity for research on microbial ecology, diversity and evolution, particularly in terms of cyanobacteria. In this work we focus on the role of environment in controlling cyanobacterial mat assembly, and begin by describing the cyanobacterial diversity of mats along environmental gradients in the McMurdo Sound region, continental Antarctica. We then evaluated the role of environmental variables in determining their composition by analysing water and microbial cyanobacterial mat samples from 25 ponds from four distinct geographic sites: McMurdo Ice Shelf, Ross Island and Upper and Lower Wright Valleys. Finally we undertook a series of laboratory experiments to determine the extent to which species composition affects mat formation. Twenty nine morphospecies are identified and described in chapter one. Four were assigned to the order Chroococcales, three to the Nostocales and 22 to the Oscillatoriales. In chapter two, we investigated the factors that appeared to determine the presence or absence of morphospecies within the cyanobacterial mat community at each sampled pond. Ross Island, McMurdo Ice Shelf and Upper and Lower Wright Valleys ponds each showed some specific features in terms of physical-chemical factors and cyanobacteria diversity, though in many cases there was considerable overlap. Multivariate analysis based on physic-chemical variables showed that the ponds from each site tended to cluster by site, though with considerable overlap, and with the two Wright Valley and two coastal sites tending to be more similar to each other. This pattern tended to be reproduced in analysis of biomass and species composition data, and we were able to identify taxa that were broadly spread across the region and others that were more restricted by area. The importance of dispersal and growth conditions in driving this pattern is discussed. In chapter 3 we developed an experiment to evaluate the role of isolated cyanobacteria strains on the mat-building process. Six cyanobacteria strains, in varying combinations, were used to grow mats under laboratory conditions: CYN-50 (Phormidium cf. autumnale); CYN-68 (Leptolyngbya A); CYN-65 (Leptolyngbya B); CYN-66 (Microcoleus sp.); CYN-67 (cf. Aphanocapsa) and CYN-72 (Nostoc sp.). The content of chlorophyll-a, exopolysaccharide and organic matter was evaluated to assess mat development. At the end of our experiment, we observed that the mats developments showed variety in terms of their morphology, that oscillatorean cyanobacteria are required for coherent mat formation, but that different strains all produced effect mat matrices. P. autumnale produced the best developed mats. In conclusion, our findings provide an increased knowledge on the Antarctica cyanobacteria taxonomy and ecology in the McMurdo Sound region. We identified a mix of broadly tolerant, widely distributed organisms and other with more local distributions and specific environmental requirements. The significance of this in terms of management of Antarctic biodiversity is discussed.

The Impact of Student-Faculty Informal Interpersonal Relationships on Intellectual and Personal Development in the University of Lagos, Lagos, NigeriaAluko, Stella Ola 05 1900 (has links)
This study was conducted to determine the impact of student-faculty informal interpersonal relationships on the intellectual development and personal achievement of students attending the University of Lagos, Lagos, Nigeria. Specifically, the work of Pascarella and Terenzini was generalized with respect to the positive influence of student-faculty interactions on academic outcomes. Additionally, the work of Pascarella and Terenzini was extended with a sample of students at the University of Lagos, Lagos, Nigeria. Eight hundred subjects were selected for the study; 621 subjects responded. One survey instrument was used. Frequencies and multiple regression analyses were used. A series of studies on student-faculty interaction has shown a significant relationship between student-faculty informal contact and student outcomes. A large number of studies have also indicated that student outcomes are not independent of students' background. Therefore, pre-enrollment characteristics were controlled for this study.
