Barracas de Praia, praia de barracas: configuração, tipo e usos na praia do futuro, Fortaleza CE

The purpose of this dissertation is to analyse the importance of the huts of Praia do Futuro to their users and to the city of Fortaleza in Ceará through the comprehension of relations between morphological categories - in urban and edified contexts - of the establishments and their use patterns. This place is one of the main recreation and leisure areas of the city, formed by six kilometres of waterfront, corresponding to a differentiated area through the coast. This space has beach huts with varied profiles: while some more simple huts persist, great complexes are being developed, building even water parks on the beach area. This study analyses relations between:i) spatial configuration (in geometric and mainly topological terms) based on the Social Logic of Space; ii) edified typology (analysing capacity, landscap treatment and program of the huts); and iii) use and environmental perception of the beach by its frequenters. There are consistent relations between the type of hut and their localization in the urban grid, of which were identified groups with different patterns: segregated (north, central and south) and integrated (north: more integrated. and south: less integrated). Such relations also reflect, in varied patterns of use and environmental perception. In spite of their strong economy, the beach huts find themselves in a fragile legal situation because they occupy the beach area, so that this study may come to assist the decision-making for the future of the region. For a sustainable development of the area by those responsible and managers it is necessary to evaluate the cultural importance of the huts at Praia do Futuro, understanding their occupation and uses.

Configurando a cidade contemporânea em Natal : os processos espaciais em Ponta Negra

This dissertation is about the spatial configuration in Natal and processes in the Ponta Negra neighborhood today. Ponta Negra has undergone a number of critical social and spatial changes due to tourism development after the 1990s. It is of special interest to consider the intensification of real estate investment after 2000, when the new airport terminal, located in the neighboring municipality of Parnamirim, was in use. Ponta Negra is the place where most tourists go to, so attracting considerable public investments. New agents of transformation have produced change in the neighborhood as well. The present study aims at analysing the spatial processes in this part of the city. Here, the spatial configuration that resulted from extended real estate investments, both public and private, in recent years, is analysed in detail. The study identifies the multually differentiated, however internally homogenous areas. The concepts of production of space, contemporanean urban development and spatial dynamics are discussed. The research is based on document analysis and field work. Results were plotted to maps and tables. A detailed analysis of the spatial processes in the Ponta Negra neighborhood is undertaken as a conclusion, considering the contemporanean global scenario

Geografia da dominação: um estudo sobre a organização espacial da terra do sal (Macau-RN)

This work aims to understand the spatial organization in the Town of Macau, State of Rio Grande do Norte, Brazil. This approach focus on bringing back the history of the town, the main personages responsible for the construction of this place, denominated "social agents", as well as its social processes and the spatial forms derived from them. As the personages and their practices were identified, it was found out the existence of a driving force for structuring, interlocking, and maintaining the actions carried out by the social agents during the time. Such actions were materialized in the urban space: "the social segregation". The social segregation takes place as a specific geography of domination. The outcome of those owning the best areas" and ways of accessibility in the urban space, varies from the enrichment by property valorization, because of the concentration of public investments of infrastructure, to the comfort of easily reaching all the daily needs related to the displacements in the urban space. In the latter case, such facility has contributed to improve life quality. While one takes advantage of the location in the urban space, others are negatively affected by the same process. This research identified the salina worker as the weakest element of this social structure, occupying the urban periphery of the town of Macau. Such area is characterized by the lack of services and urban equipment in opposition to the center of the town, the locus of elite. This way, it is established the most known segregation pattern: center x periphery, in which the space acts as a mechanism of segregation

Sistemas de informação geográfica e análise espacial de dados como ferramentas para determinação de agregação espacial de doenças: a hanseníase como modelo

This work demonstrates the importance of using tools used in geographic information systems (GIS) and spatial data analysis (SDA) for the study of infectious diseases. Analysis methods were used to describe more fully the spatial distribution of a particular disease by incorporating the geographical element in the analysis. In Chapter 1, we report the historical evolution of these techniques in the field of human health and use Hansen s disease (leprosy) in Rio Grande do Norte as an example. In Chapter 2, we introduced a few basic theoretical concepts on the methodology and classified the types of spatial data commonly treated. Chapters 3 and 4 defined and demonstrated the use of the two most important techniques for analysis of health data, which are data point processes and data area. We modelled the case distribution of Hansen s disease in the city of Mossoró - RN. In the analysis, we used R scripts and made available routines and analitical procedures developed by the author. This approach can be easily used by researchers in several areas. As practical results, major risk areas in Mossoró leprosy were detected, and its association with the socioeconomic profile of the population at risk was found. Moreover, it is clearly shown that his approach could be of great help to be used continuously in data analysis and processing, allowing the development of new strategies to work might increase the use of such techniques in data analysis in health care

Da Pedra do Rosário ao Pantanal: Espaço e Urbanização no Passo da Pátria (Natal/RN)

The Passo da Pátria is one of the areas of housing in the city of Natal/RN, presents characteristics of insecurity on ways to live and access to goods and services. The project of urbanization called Integrated Project Passo da Pátria implemented since 2002 by the public power wants to change this picture. In Passo da Pátria system of classifications of space operated by the villagers signals to singularities that allows the identification of four pieces: Pedra do Rosário , Passo , Areado and Pantanal . The actions of the Project of Urbanization promote a new socio-space configuration. Our objective is to examine ways of appropriation of space in Passo da Pátria , built by the residents, which included their cultural practices giving symbolic meaning to the four pieces. The methodological procedures consisted of: literature review of the themes of the City, Urban, Segregation socio-space, Space, the Public Policies in urban area and texts on the Passo da Pátria ; desk research and interviews with old residents, recent residents, and these: men, women, young, and leaders of the Passo da Pátria . The evaluation of the data indicates that residents live positively the action of the public power as regards the expansion of urban infrastructure and services. At the same time, negative value of the shares removal of residents and idea of integration for the different pieces that form the Passo da Pátria , for them, these actions desconstroem times, experiences and narratives that are expressed in their relations with the space in which live

Variabilidade espacial de atributos químicos de um argissolo para aplicação de insumos à taxa variável em diferentes formas de relevo

A agricultura de precisão implica análise da variabilidade espacial de fatores de produção e a aplicação de insumos de forma localizada. Várias são as causas que condicionam a variabilidade espacial dos solos, sendo o relevo um dos fatores mais importantes. O presente estudo teve por objetivo analisar a variabilidade espacial dos atributos químicos do solo e a elaboração de mapas de necessidade de aplicação de insumos de forma localizada, em áreas com diferentes formas de relevo. Duas parcelas de 1 ha cada foram delimitadas em áreas com topografia côncava e convexa. Foram retiradas, em cada área, 242 amostras de solos em 121 pontos, nas profundidades de solo de 0,00-0,20 m e 0,20-0,40 m. Os resultados de análise química foram submetidos às análises da estatística descritiva, geoestatística e interpolação por krigagem. A área convexa apresentou maior variabilidade espacial do solo em relação a área côncava. A adoção da agricultura de precisão possibilitou economia de aproximadamente 25 kg ha-1 de P2O5 na área côncava.

Reestruturação do setor industrial e transformação do espaço urbano de Campina Grande PB : a partir dos anos 1990

The central objective of this thesis is studying the changes in the industrial sector of Campina Grande-PB, in the years 1990, about the size of that space and urban sector. The hypothesis that guides this work is that there was a reconfiguration and industrial space in recent years, the result of the restructuring of productive capital and, secondarily, public policies - economic, urban etc. - implemented in the municipality in the years 1990. This reconfiguration industrial meant thepredominance of certain productive segments of the industry and the shift towards urban-industrial areas (industrial districts). This work is guided in these two axes to explain the changes in the industrial campinense and its consequent impact on the urban development of Campina Grande. It is understood by reconfiguration industrial changes in industrial structure, namely the preponderance of one or more productive segments on the other, changing the scenario of production, employment and the number of establishments. In this study, are considered as institutional structures of support and assistance to industry, the various institutions that directly and indirectly, contribute to the development of productive activity. These structures are the first to undergo institutional changes, physical and policies because of intrinsic connection with the industry. The institutional structures contribute to the development of industrial activity and urban development. In Campina Grande, these institutions are important for facilitating the development of certain segments. In this work, sought to identify the current configuration industrial campinense, explaining how the restructuring of production transformed the industry, modifying the urban space in Campina Grande - PB, to direct itself to specific urban areas, from the early 1990

Variabilidade espacial da emissão de CO2, da temperatura e umidade de um latossolo desprovido de vegetação sob diferentes lâminas de molhamento

The irrigation application is one of the most useful techniques in tropical environments, especially during dry seasons. In this study, CO2 efflux, temperature and soil moisture were studied in a field sampled with a grid having 48 points distributed in 35 x 25 m, under irrigation promoted by a sprinkler located at the center of the area, provoking different levels of water deposition, with maximum irrigation levels of 44.4 and 62.2 mm in points closer to the sprinkler. The results show that the emissions, temperature and moisture were strongly affected by the two irrigations events, having a total water level added of 106,6 mm for the points next to the sprinkler and zero for the most distant points from it. The maps of space variation of the variables, as well as the linear correlation between them, indicate that the emissions were positively related to the soil moisture and negative correlated to the soil temperature only after the irrigations events. The special variability models of soil CO2 emission changed from exponential to spherical after the irrigations events. Such results indicate that soil moisture is among possible controlling factors of the soil CO2 emission, because even with reductions in soil temperature provoked by the wetness, emissions increased strongly.

Influência do relevo e erosão na variabilidade espacial de um Latossolo em Jaboticabal (SP)

Com o objetivo de avaliar as relações entre formas de paisagem e erosão em um Latossolo Vermelho eutroférrico (LVef) por meio de técnicas geoestatísticas na Fazenda Santa Isabel, município de Jaboticabal (SP), identificaram-se modelos de paisagem côncavo e linear. Coletaram-se amostras de solo em ambas as formas de paisagem em uma malha regular espaçada de 50 x 50 m em sete transeções na profundidade de 0,00-0,20 m, totalizando 412 pontos em 93 ha. Determinou-se a erodibilidade dos solos pelo método indireto, granulometria, bem como o carbono orgânico para cada ponto da malha, sendo esses valores usados na estimativa do potencial natural de erosão (pne). Os dados obtidos das propriedades de solo, erodibilidade e potencial natural de erosão foram analisados por meio de estatística descritiva e geoestatística com a modelagem de semivariogramas, sendo este utilizado para a confecção de mapas de krigagem. Segundo os resultados, as propriedades do solo e do pne apresentaram maior variabilidade espacial na pedoforma côncava, apesar de esta forma de paisagem apresentar menores perdas de solo por erosão e menor variabilidade espacial da erodibilidade. Deste modo, conclui-se que a erosão não adicionou variabilidade espacial para as propriedades do solo na mesma magnitude do relevo.

Variabilidade espacial de atributos do solo para adoção do sistema de agricultura de precisão na cultura de cana-de-açúcar

O objetivo do presente trabalho foi avaliar a variabilidade espacial de atributos de Latossolos sob cultivo de cana-de-açúcar na região de Jaboticabal (SP). Foram feitas amostragens do solo a intervalos regulares de 50 m, em uma área de 90 ha, nas profundidades de 0,00-0,20 e 0,60-0,80 m para determinação de pH, CTC, V % e teores de matéria orgânica, P, K+, Ca2+, Mg2+, H + Al e argila. Os dados foram submetidos às análises: estatística descritiva, geoestatística e interpolação por krigagem. Os alcances de dependência espacial para os atributos químicos do solo e teores de argila na camada de 0,60-0,80 m de profundidade foram menores, quando comparados àqueles referentes à camada de 0,00-0,20 m. Estes resultados demonstraram maior descontinuidade na distribuição espacial dos atributos do solo na camada de 0,60-0,80 m de profundidade dos Latossolos, indicando que essa classe de solos não apresentou homogeneidade de seus atributos como conceituadamente a ela foi atribuída. O manejo no solo alterou a dependência espacial dos atributos do solo na camada superficial de forma a diminuir a variabilidade espacial dos atributos químicos do solo em relação à camada mais profunda. A investigação da variabilidade espacial de atributos químicos e do teor de argila da camada superficial e subsuperficial dos solos proporcionou condições para a definição de zonas homogêneas de manejo, o que permite a adoção do sistema de agricultura de precisão.

Distribuição espacial de Toxoptera citricida (Kirkaldy) (Hemiptera: Aphididae) na cultura de citros

O estudo da distribuição espacial de pragas é fundamental para elaboração de planos de amostragem para o uso do manejo integrado de pragas. Para o afídeo Toxoptera citricida (Kirkaldy), estudou-se a distribuição espacial em talhões de pomares de citros comerciais de laranja-doce [Citrus sinensis (L.) Osbeck] da variedade Pêra, com 5; 9 e 15 anos de idade, durante o período de setembro de 2004 a abril de 2005. Foram realizadas 14 amostragens de número de T. citricida em intervalos aproximados de 15 dias entre as mesmas, utilizando-se de armadilhas adesivas de cor amarela (0,11 x 0,11 m) fixadas à planta, a 1,5 m de altura aproximadamente. As armadilhas foram distribuídas na área, a cada cinco plantas na linha, em linhas alternadas, totalizando 137 armadilhas no talhão com 5 anos, 140 no talhão com 9 anos e 80 no talhão com 15 anos. Os índices de dispersão utilizados foram: razão variância média (I), índice de Morisita (Idelta), coeficiente de Green (Cx) e expoente k da distribuição Binomial Negativa. O índice que melhor representou a agregação do pulgão foi o expoente k da distribuição Binomial Negativa, e a distribuição binomial negativa foi o modelo que melhor se ajustou aos dados. Através destas análises, verificou-se que a maioria das amostragens apresentou uma distribuição agregada da população de T. citricida.
