OVERLAND FLOW AND SURFACE RUNOFF / Hydrological Science and Engineering

Cape Verde, off the coast of Senegal in western Africa, is a volcanic archipelago where soil and water conservation techniques play an important role in the overall subsistence of half a million inhabitants. In fact, the step slopes in the more agricultural islands due to it's volcanic origin, together with semi-arid and arid environments (the country is located in the Sahelian region), characterized by a very irregular wet season, with high intensity rainfall events, make life tough. The hard conditions lead during the first half of the XX century to frequent cycles of drought with severe implications on the local populations, with impressive numbers of deaths by famine, and a decrease of the number of local inhabitants by more than halve in some islands. Maintain the soil in place and the water inside the soil was there after a mater of survival, and the CapeVerdians implemented over the last half century a number of soil and water conservation techniques that cover all the landscape. In this work, we monitored a number of slope soil and water conservation techniques, such as terraces, half moons, live barriers, etc, together with two cultural strategies, used to plant corn and beans on one side and peanuts on the other, with a semi-quantitative methodology, to evaluate their effectiveness. A discussion is given on the costs and effectiveness of the techniques to reduce overland flow production and therefore erosion, and to promote rainfall infiltration.

Major: Electronics and Communication Engineering

Today, information technology is strategically important to the goals and aspirations of the business enterprises, government and high-level education institutions – university. Universities are facing new challenges with the emerging global economy characterized by the importance of providing faster communication services and improving the productivity and effectiveness of individuals. New challenges such as provides an information network that supports the demands and diversification of university issues. A new network architecture, which is a set of design principles for build a network, is one of the pillar bases. It is the cornerstone that enables the university’s faculty, researchers, students, administrators, and staff to discover, learn, reach out, and serve society. This thesis focuses on the network architecture definitions and fundamental components. Three most important characteristics of high-quality architecture are that: it’s open network architecture; it’s service-oriented characteristics and is an IP network based on packets. There are four important components in the architecture, which are: Services and Network Management, Network Control, Core Switching and Edge Access. The theoretical contribution of this study is a reference model Architecture of University Campus Network that can be followed or adapted to build a robust yet flexible network that respond next generation requirements. The results found are relevant to provide an important complete reference guide to the process of building campus network which nowadays play a very important role. Respectively, the research gives university networks a structured modular model that is reliable, robust and can easily grow.

A motivação e satisfação organizacional como factores essenciais de conquista de melhores resultados empresariais: Estudo de caso no Hotel Marine Club Beach Resort

A motivação no âmbito organizacional está relacionada à qualidade de desempenho e esforços de seus colaboradores, constituindo a energia motriz para atingir os resultados desejados. Com a chegada da globalização, o avanço tecnológico, aumento da competitividade entre as empresas, custos de contratação, treinamentos e processo de automação industrial, a exigência do melhor desempenho de seus colaboradores está cada vez maior. Por esse motivo, as empresas estão sempre buscando alternativas que motivem seus colaboradores, com o intuito de proporcionar um melhor clima organizacional e desempenho dos seus profissionais. O presente trabalho tem por objectivo estudar a satisfação dos trabalhadores como factores essenciais de motivação e sucesso empresarial no Hotel Marine Club Beach Resort, da ilha de Boa vista. Além de se valorizar o conhecimento técnico e científico do profissional é igualmente importante ter em consideração estas condicionantes (satisfação e motivação no trabalho), que embora sejam de carácter psicológico e emocional, desempenham um papel preponderante na produtividade do trabalhador, acabando por influenciar o sucesso de qualquer empresa. Conclui-se que o grau de motivação e satisfação do hotel é bom, o ambiente organizacional também é satisfatório mas é preciso que o hotel melhora as políticas de gestão tais como, benefícios em relação a promoções, salários e valorização do colaborador para mantê-los motivados e satisfeitos no trabalho.
