At a time of changes on the territory during the 19th century, the political and socioeconomic elites of the province and later State of Rio Grande do Norte evolved a discourse in order to justify the permanence of Natal as a city holding a status of capital. In this work we analyze the means employed by the ruling classes to impose their wish to raise Natal to an outstanding position among the existing cities by intervening on the territory during a period of one hundred years (1820-1920). During that time, which was characterized by changing commercial flows and technological development, the elites interventions were essentially directed to the implementation of modes of transportation, especially the railway. We try to understand the reinforcement of Natal as a capital city not only in political and administrative terms, but mainly in a commercial and symbolic manner, through the discourse and interventions undertaken by the local administrative elites, who stimulated the creation of a set of relations on the territory that also imprinted visible marks in the capital s urban fabric. These interventions were based upon the establishment of an infrastructure for exporting the State s production, firstly through and despite the Potengi River, and later on by the construction of railways. Although the project of Natal s hegemony had been outlined before the establishment of the railway network, in both cases the ultimate objective was to reinforce and develop the capital city as a commercial urban center to the detriment of other cities

Transport systems involved the use of territory in different Brazilian cities with regard to the occupation of road systems in urban areas. The implementation of systems engineering and transport infrastructure such as roads (roads), signs, stops, stations and complex road (bridges, viaducts and tunnels) are not used in the same way in the area. The subway is not even use the bus and vice versa. The time spent in travel, the time to access and the number of trips made by passengers in each way of transport is not the same. The use of transport systems in the territory, therefore, takes place through a whole in the current period we are in the technicalscientific and informational. This work addresses, however, the area used as a synonym of geographical area, analyzed by two categories of analysis, systems of objects formed by the fixed and the systems formed by the action flows. The system analyzed is the public transport by bus and population displacement that makes using this medium with source destination from home to work and has as empirical cut the Lagoa Azul located in the district administrative area north of Natal / RN. The general objective of this research is to understand the extent to which public transport has contributed to the socio-spatial accessibility of the residents of Barrio Blue Lagoon, located in Natal-RN, emphasizing the way home and the workplace. To reach the general objective of this dissertation, a study was made in light of the line which the methodological empirical facts, statistical data and theoretical knowledge of the events that occur in the quarter related to the Lagoa Azul economic aspects. Use for this, the concepts of mobility and Accessibility

O conceito de desempenho ambiental tem sido utilizado como forma para revelar as relações da empresa com o meio ambiente e com a sociedade, constituindo um parâmetro de análise da sua postura diante das questões sócio-ambientais. A avaliação dos aspectos e impactos ambientais gerados por determinada atividade é um instrumento da gestão ambiental, sendo aplicado, nesse trabalho, em uma pedreira de diabásio, na área de expansão urbana, no município de Campinas (SP). Foram avaliados os aspectos e impactos das etapas produtivas da pedreira e de suas instalações administrativas. Os impactos adversos mais significativos levantados foram a sobrepressão atmosférica e a vibração do terreno, causando desconforto à comunidade. Após tais levantamentos, algumas ações de melhoria foram implantadas pela empresa e resultaram na diminuição das reclamações por parte da comunidade; outras medidas, pró-ativas, devem ainda ser implementadas, principalmente aquelas voltadas para a prevenção de impactos negativos e a preservação do meio ambiente, além da recuperação da área degradada, como medida reativa.

Objetivou-se avaliar as alterações fisiológicas, produtivas e comportamentais em cabras da raça Alpina submetidas ao transporte. Foram utilizadas 12 cabras pluríparas em final de lactação. A produção, composição e contagem de células somáticas do leite e as respostas comportamentais das cabras durante a ordenha foram mensuradas três dias antes, no dia e três dias após o transporte. Também foram colhidas amostras de sangue antes (-120 e -10 minutos) e após (10 e 120 minutos) o transporte para determinação dos níveis de cortisol e glicose. Entre os comportamentos estudados durante a ordenha, apenas sobrepasso e coçar foram significativamente influenciados pelo transporte. Também foram observados aumentos significativos nos níveis de glicose e cortisol 10 minutos após o transporte. Os níveis de glicose permaneceram elevados até 120 minutos após o transporte, enquanto os de cortisol aos 120 minutos foram semelhantes aos observados antes do transporte. O transporte com retorno às instalações conhecidas e ao manejo rotineiro de ordenha causa pequenas alterações fisiológicas e comportamentais que não alteram significativamente a produção, a composição e a contagem de células somáticas do leite.

The environmental analysis is an important tool used in forecasting and mitigation of environmental problems. Focusing on the occupation of marginal areas of the Corumbataí River in an urban stretch in the city of Rio Claro (SP), this study aimed to gather information on situations of risk, both to the environment and the population, verified in that area. Through field observation and in specific studies, the geological and geotechnical aspects, the characteristics of surface waters and aspects of urbanization were analyzed. The results show that the environmental problems diagnosed are related to lack of planning in the occupation of the area. Moreover, the natural characteristics of the physical environment expose people to risks such as floods and soil slides.
