Sistema integrado para tomada de decisão espacial em situações de derramamento de óleo no litoral norte do Estado do RN

The northern coast of Rio Grande do Norte State (RN) shows areas of Potiguar basin with high activity in petroleum industry. With the goal of avoiding and reducing the accident risks with oil it is necessary to understand the natural vulnerability, mapping natural resources and monitoring the oil spill. The use of computational tools for environmental monitoring makes possible better analyses and decisions in political management of environmental preservation. This work shows a methodology for monitoring of environment impacts, with purpose of avoiding and preserving the sensible areas in oil contact. That methodology consists in developing and embedding an integrated computational system. Such system is composed by a Spatial Decision Support System (SDSS). The SDSS shows a computational infrastructure composed by Web System of Geo-Environmental and Geographic Information - SWIGG , the System of Environmental Sensibility Maps for Oil Spill AutoMSA , and the Basic System of Environmental Hydrodynamic ( SisBAHIA a System of Modeling and Numerical Simulating SMNS). In a scenario of oil spill occurred coastwise of Rio Grande do Norte State s northern coast, the integration of such systems will give support to decision agents for managing of environmental impacts. Such support is supplied through a system of supporting to spatial decisions

Caracterização geomorfológica e paleogeográfica da plataforma continental adjacente a foz do Rio Apodi-Mossoró, RN/Brasil

The brazilian marginal basins have a huge potential to generate and accumulate petroleum. Incised valleys which are eroded in response to a fall of relative sea level are related to potential reservoir as well, modern drowned-valley estuaries serve as harbors to petroleum and salt industries, fisheries, waste-disposal sites and recreational areas for a significant fraction of the world s population. The combined influence of these factors has produced a dramatic increase in research on modern and ancient incised-valley systems. This research is one expression of this interest. The integrated use of satellites images and high resolution seismic (bathymetry, sides scan sonar) was used on the Apodi River mouth-RN to characterizes the continental shelf This area is located at the Potiguar Basin in the NE Brazilian Equatorial Atlantic margin. Through bathymetric and side scan sonar data processing, a digital Terrain Model was developed, and a detailed geomorphologic analysis was performed. In this way was possible to recognize the geomorphologic framework and differents sismofacies, which may influence this area. A channel extending from the ApodiMossoró river mouth to the shelf edge dominates the investigated area. This structure can be correlated with the former river valley developed during the late Pleistocene sea level fall. This channel has two main directions (NW-SE and NE-SW) probably controlled by the Potiguar Basin structures. The western margin of the channel is relatively steep and pronounced whereas the eastern margin consists only of a gentle slope. Longitudinal bedforms and massive ridges also occur. The first are formed doe to the shelf sediment rework and the reef-like structures probably are relics of submerged beachrock-lines indicating past shoreline positions during the deglacial sea-level rise. The sub-bottom seismic data allow the identification of different sismic patterns and a marcant discontinuity, interpreted as the Upper

Outra leitura do "outro lado":o espaço da Zona Norte em questão

It analyzes the production of the space of the North Zone of Natal/RN, of the beginning of its formation - decade of 1970 - a present time, under the optics of the urban planning and of the administration of the territory. Inside of that path, it examines the interests that orientated the "creation" of the referred space, as support to the process of urban planning and of administration of the territory; as well as the recent processes that evidence a new partner-space dynamics, which is configured, now as an incipient insert of the North Zone to the context natalense urban-space, now as a "reedition" of its report process of partner-space segregation. It stands out that, while in the beginning of the formation of the North Zone, the State was made the main actor, making possible the expansion of the capital in the north sense of the city of Natal, through the implantation of the Industrial District of Natal (DIN) and of the expansion of the habitational politics of the House of Financial System (SFH); at the present time, the new space processes are configured through the economical inclination, through expansion of the tertiary section in the city of Natal. It is based in bibliography regarding the theme in focus, in primary and secondary sources, as well as in processes and forms that were unchained in the North Zone along the research. It analyzes the North Zone then in its group, the one that makes possible apprehend the inherent conflicts to the process of production-appropriation of the urban space, for the several social actors - the State, the capital and the society - that dispute the control of the production of the space according themselves their interests

Aproveitamento de vísceras não comestíveis de aves para elaboração de farinha de carne

No presente trabalho, estudou-se o processamento das vísceras de frango (Gallus domesticus) e das ratitas avestruz (Struthio camellus) e ema (Rhea americana), processadas da mesma forma, com o objetivo de elaborar farinhas. A qualidade e controle de produção dessas farinhas foram avaliados por meio de parâmetros tecnológicos exigidos pela legislação vigente. Basicamente, a matéria-prima foi cozida e esterilizada, filtrada em peneira (para a separação do óleo), moída, seca em estufa e analisada. Foram obtidos dados de rendimentos de produção, de composição de nutrientes, de digestibilidade em pepsina, do valor calórico, determinados os teores de cálcio e fósforo, e realizados estudos da estabilidade da farinha durante o armazenamento (Salmonella, pH, índice de acidez e TBA). Os resultados mostraram que a produção de farinha pelo processamento das vísceras de avestruz e ema é viável, seus parâmetros de qualidade atendem, em grande parte, às exigências, mas, para um emprego imediato (uso regular) na elaboração de rações, necessita de alguns ajustes (correções) de parâmetros físico-químicos (nutrientes).
