Espaços de pobreza e mobilidade urbana: os deslocamentos da população de baixa renda em Natal/RN

This dissertation is an attempt to understand how families with an income of up to three minimum wages and living in different Areas of Demographic Expansion (AEDs) of Natal municipality specifically in the districts of Igapó and Salinas (North Administrative Zone of the city), Ponta Negra (South Administrative Zone), Santos Reis, Praia do Meio, Areia Preta and Mãe Luíza (East Administrative Zone) and Felipe Camarão (West Administrative Zone) solve their problems of urban mobility. It is, therefore, a reflection upon the mobility needs of poor urban households as expressed in terms of origin-destiny displacements for specific movements (house-work, house-school, house-shopping, house-healthcare and house-leisure), all of which being analyzed within the relationship between public transportation and poverty spaces of the city. In order to develop the study, theoretical aspects and themes related to the production of the urban space, to social and spatial segregation, to urban mobility and to transportation were confronted with the collected data referring to the urban population previously selected. One of the research main findings is the crucial role mobility plays in the social differentiation of such people living in Natal and that any policy for the improvement of their living conditions must take mobility issues into account

Adequação bioclimática para os espaços urbanos abertos do centro de Fortaleza, CE

This research presents a study investigating the correlation between the environmental-physycal charcateristics of cities and the formation of its micro-climates. The study was conducted in the central area of Fortaleza characterized as a stable and consolidated area, where the city originated and currently faces serious problems in its urban dynamics. The points of measurements were determined by the elaboration and analysis of topography maps, height of buildings, land use, type of surface coating and vegetation, following the methodology of Katzschner (1997). A zoning map was then determined, according to common morphological characteristics of the 12 measurement points, which were based on a set of Romero s (2001) bioclimatic criteria. Air measurements, temperature, humidity, intensity and direction of winds were made in transect form in two different circuits in the study area, with six points of data collection in each area, in three different times: 6:00 am, 1:00pm and 7:00pm, during two periods of the year: August 2008 and March 2009. The results verified the influence of different environmental-physical types in the behavior of the climatic variables that were collected. A verticalização tão condenada em algumas situações se bem equilibrada e controlada pode reduzir as temperaturas do ar através do sombreamento dos espaços urbanos e possibilidade de maior permeabilidade a ventilação natural. The highest average air temperature and lower humidity were recorded at the point I at all times. This situation may have been in result of the high density, poor vegetation and extended paving of the ground. According to the results, it s clear the positive influence vegetation has on easing air temperature. Another indicator observed that areas with a greater variation in building heights tend to present decreased average air temperature. High rise structure, planned in accordance to urban air quality parameters, can reduce air temperatures by the shading of urban spaces and the possibility of greater penetration of natural ventilation

El trabajo comprende, dentro de una visión macro, una importante compilación de datos, que se ha logrado mediante el inventario, análisis de muestreos, levantamientos fotográficos, análisis visual paisajístico de las áreas verdes y el manejo de datos técnicos e indicadores.

Qualidade do ar interior e conforto térmico : um estudo em espaços de estacionamento em Natal/RN

The recent tendency to utilize parking lots for other purposes has demonstrated that more time has been spent by visitors, mainly in great cities. Therefore, this paper investigates the thermal comfort and the air quality indoors in areas specifically used as parking lots by analyzing the direct relation between such environments and vehicular pollution. The thermal comfort and the quality of air indoors in parking lots with different architectonic typology (ground-floor and underground) are also studied, aiming to contribute to the proposition of suitable new areas designated to human usage. Field research was done, in two distinct periods within different weather conditions (January and July) in, two naturally cooled, parking lots located in Natal - RN. The internal environment agents were measured by using tools for air temperature, humidity, speed and direction; interviews with employees and visitors and chemical analysis through appropriate tools to analyze specific material, carbon monoxide and ozone. The results showed that chemical agents densely concentrate mostly in the closed parking space, aggravated by weather conditions, which dissatisfied the visitors. Still, it was shown that architectonic typology, alongside topographical aspects compromise internal environmental conditions, which increases the retention of pollution, leading to dissatisfactory thermal comfort levels and becoming less suitable for usage by visitors considering air and thermal comfort aspects. Consequently, they are not suitable for human stay due to the poor quality of the indoor air

Depois das fronteiras: a formação dos espaços de pobreza na periferia norte de Natal-RN

The periphery of the city of Natal was built during the last 20 years, trough informal land developments. This dissertation analyses the urbanization of Natal`s North Zone, the largest residential area in the city where 40% of the population lives. This urban space is characterized as a space of poverty because of its majority of low income dwellers as well as lack of infrastructure. The main objective here is to identify and characterize this space as well as resulting segregation. Variables as income, space morphology, residential typology and the history of real estate development as well as dweller`s history of life are analysed

Espaço público e sociabilidade urbana: apropriações e significados dos espaços públicos na cidade contemporânea

Study public space is studying the city and its dynamics through a representation point. The changes that are observed in these spaces and in the relations established there, or with it, are related to changes that occurred in the city as a whole, in the urban way of living. Study public space allied to urban sociability permits an even better focus on this relation between people in these spaces and with the spaces and in the consequences and fragile aspects this relation can impose to people and cities. This work is aimed towards this relation between public space and urban sociability. Through a conceptual/theoretical discussion aims, specifically, comprehend how to establish and what is the relation between urban space and urban sociability (appropriation/perception of place, tendencies of seclusion), from an isolated analysis of each one of these themes in the contemporaneous city. The Brazilian public space has peculiar characteristics, arising from its historical process of construction, also influenced by the public sphere fragile construction that permeates it, as well as more recent variables such as the sensation of insecurity and commodification of these places. The urban sociability influences and is influenced along all this process of significance and reframing of the public space. The conceptual discussion about each isolate variable provides the necessary coverage for discussion and analysis of the relation between them and the consequence of this relation in the city, such as the notation of relevant experiences of this process of revaluation of the public space. The hereby search is not through a path to reestablish the relation as it already existed, but also for an understanding of the dynamic as is established today and for existing possibilities for maintenance and appreciation of the relation between people and the city by believing in its importance to urban life

Caracterização da fração de óleo de café extraido de grãos sadios, verdes e preto-verdes, e a influência na adição deste na sensorial de café liofilizado

The application of roasted coffee oil directly on freeze dried soluble coffee is used to minimize the formation of fine poder which adhere on the glass packaging, which results in a negative visual appearance, as well as contributes to the aromatic impact when opening the packaging. The coffee oil is considered a high cost product obtained from Arabica coffee beans, previosly selected and roasted, by mechanical press. In Brazil the coffee culture and marketing results in the selection of the beans by type of defects and beverage, the volume of exportation works with types of coffee beans with low quantity of defects resulting in a large volume of defective coffee beans trading on the domestic market. Nevertheless, coffees which present defective grains like green, black-green beans present differences in the final flavor of the roasted coffees. The aim of this study was to evaluate the chemical composition of the oils extracted from grains classified as normal, green and black-green, at natural and roasted conditions. The oil was obtained by cold extraction using solvents of different polarities, and yield was calculated as well as its fatty acid composition. The oil of the roasted defective coffee grains was also used to prepare drinks of lyophilized soluble coffee in order to verify if jugdes were able to differenciate the sensory caracteristics of the beverages, in comparison to the product prepared using commercial oil obtained by mechanical pressing. Samples of oil obtained from defective grains showed similar extraction yields compared to hot extraction. Cromatographs of oils of the deffective grains did not showed differences compared to normal grains. In relation to the sensory analysis of the soluble coffee beverages, it was verified that when applying oils of light roasted black-green beans or oils of medium and dark roasted green beans obtained with rapid process, judges had more difficulties to distinguish differences between samples. Economic viability demonstrated that with the actual prices of the coffee beans, the use of defective beans could reduce in 64% the costs of the raw beans.

A produção do mobiliário urbano nos espaços públicos :o desenho do mobiliário urbano nos projetos de reordenamento das orlas do Rio Grande do Norte

This work aims to analyze and evaluate the Urban furniture designed to public areas according to the Revitalization planning for Rio Grande do Norte coastland, defining visual relations among urban elements in the landscape of revitalized public urban areas with cultural, paisagistic and touristic values and the design process used for developing urban furniture to those areas, observing the incoming consequences use to that process in a specific urban context which alters use, functions, cultural images as well as social values attributed to each particular place. Environmental perceptions, legibility of local cultural references and their representation through the design of urban elements, act in a positive or negative manner over the inhabitants cognition process of some particular revitalized area, determining new use and attributions to those areas. Designs for coastal urban interventions try excessively to standardize technical media, construction materials and planning configurations, creating artificial sceneries that segregates users, imposing new structures and usage, generating, consequently, the so called non-places and burlesque regionalism. The research is divided into 4 chapters: 1) Theoretical support (Industrial design; Urban furniture; Public urban spaces; Urban image and environmental perception; Urban occupation and interventions in coastland areas); 2) Methodological procedures and data collection; 3) Analysis of Rio Grande do Norte coastal areas and their urban interventions; 4) Final considerations and Industrial Design contributions to the subject

Localização em espaços interiores por luz visível para robôs móveis

Esta dissertação investiga a localização em espaços interiores através da comunicação por luz visível para robôs móveis, com base nos LEDs fixos nos edifícios, dando particular atenção à simulação e desenho do sensor, com vista ao desenvolvimento de um sensor de localização. Explica-se o crescimento da tecnologia LED e da constante necessidade de localização do homem em espaços interiores. Apresentado algumas características do LED e dos foto-detetores existentes. Com uma breve referencia a algumas das comunicações por luz visível de baixo débito possíveis de implementar. O desenvolvimento do protótipo do sensor inicia-se, principalmente, pela simulação de alguns dispositivos essenciais e das suas caraterísticas, como o emissor LED no controlo do ^angulo de meia potência (HPA) e a altura a que se encontra, e no recetor foto-díodo e a sua restrição de campo de visão (FOV). Simula-se o sensor pretendido com o número de foto-díodos necessários otimizando o espaço físico disponível e fazendo não só um refinamento no FOV mas também na distribuição espacial dos foto-díodos com funções predefinidas para a redução de incertezas de decisão de localização do robô. Estes resultados permitiram a construção física do sensor, desde o suporte para os foto-díodos, tendo em conta todas as medidas durante as simulações, e terminando com o desenvolvimento dos sensores e a sua integração completa. O tratamento de dados da leitura dos sinais recebidos do sensor são tratados por um microcontrolador, permitindo calcular parâmetros fundamentais no cálculo da posição. No final, os resultados teóricos bem como os práticos obtidos ao longo do desenvolvimento e possíveis propostas para trabalhos futuros que beneficiam desta investigação

Aplicação foliar de molibdênio em adubos verdes e o desempenho do feijoeiro em sucessão

The knowledge of molybdenum application in legumes on the availability of N, by BNF, increased enzymatic activity and the residual effect caused on crops growth and yield can contribute to the greater scientific understanding involved in green manure processes. The aim of this study was to evaluate the Mo application and the N from Crotalaria juncea and Canavalia ensiformis green manures on common bean performance. Were conducted field experiments for the crops succession system (green manures - common bean) and laboratory essays for the enzymatic activities. Green manure production was installed in a factorial arrangement 2 x 4, with two green manure legumes species, sunnhemp (Crotalaria juncea) and jack beans (Canavalia ensiformis), and four Mo doses (0, 40, 80, 120 g ha-1) in the form of sodium molybdate (Na2MoO4), foliar applied, in a randomized block design with four replicates. For succession crop (common bean) additional treatment was added, beans grown without any fertilization, following the same experimental design from the previous crop. The dry matter decomposition and the N mineralization of green manure were monitored through collection of residues over time, by using the litter bags method. In laboratory were carried out tests of nitrate reductase activity in green manures and common beans at 90 and 66 days after sowing, respectively. The sunnhemp responded linearly positively to the application of Mo as the dry matter and N accumulation. While the jack beans presented a negative quadratic response for dry matter and there was no adjustment of regression models to N. The jack beans showed a higher decomposition rate and N mineralization compared to sunnhemp. The half lives for decomposing 50% of dry matter on the soil was 123 and 104 days to sunnhemp and jack beans, respectively, and 50% of N present in the residues was mineralized at 93 and 85 days. In common bean, differed from the control for number of pods the dose of 40 g ha-1 of Mo in both species of green manures and the dose 80 g ha-1 of Mo in jack beans. For number of grains only in sunnhemp on the dose of 40 g ha-1 of Mo differ from the control. The nitrate reductase activity was influenced by developmental stage of green manure species. In common bean, the activity of nitrate reductase was up to three times higher than the dose 0 g ha-1 of Mo compared to treatment with application of Mo in both species. There was no effect of Mo doses or species of green manure on common bean yield.

As rugosidades do Ciberespaço: um contributo teórico aos estudos dos web espaços informacionais

Este artigo apresenta uma contribuição à área da Ciência da Informação, em sua dimensão teórica, ao trabalhar conceitos do geógrafo Milton Santos como elementos norteadores para uma análise das infraestruturas físicas e tecnológicas que compõem o que intitulo como web espaços informacionais. Balizado também em conceitos do filósofo Gilbert Simondon, propõe-se identificar as estruturas e objetos técnicos que compõem estes espaços em seu processo de concretização, reconhecendo nestes mesmos, práticas recorrentes de um cenário global marcado pela concentração de capital e conhecimento científico tecnológico. O artigo abre, com isso, a proposição de que as formas de visibilidade e acesso da informação nos web espaços informacionais constituem-se a priori como rugosidades de uma estrutura já existente apesar das inovações quanto aos objetos, plataformas e sistemas informacionais em constante ebulição.

Roda dos sentidos: a formação continuada de professores em espaços de coletividade

A dissertação de mestrado aqui apresentada está vinculada ao Programa de Pós Graduação em Educação – PPGEdu, da Universidade Federal do Rio Grande – FURG, situada na linha de pesquisa Culturas, Linguagens e Utopias. O objetivo do estudo é contribuir para que os professores possam pensar em outras práticas de formação docente dentro dos espaços educativos nos quais atuam, desenvolvendo suas ações pedagógicas, a partir da reflexão sobre cotidiano docente no coletivo. A pesquisa envolve um grupo de professores que se propôs a estudar a categoria trabalho e seus entrelaçamentos com o trabalho docente a partir da perspectiva marxista. Tal grupo organizou-se tendo em vista a metodologia das Rodas de Formação, conforme a perspectiva de Warschauer, intitulando-se Roda dos Sentidos. Como corpus de análise foram utilizados os registros escritos em um portfólio coletivo, realizado a cada semana por um dos professores da Roda. Tal escrita era alternada entre os sujeitos para que, assim, todos contribuíssem, ao seu modo, na composição dos registros da Roda dos Sentidos. Foram analisadas as escritas dos anos de 2011 e 2012, buscando-se responder ao questionamento: ―que significados de formação docente são vivenciados em espaços coletivos como os da Roda dos Sentidos?‖ A análise dos dados foi inspirada na Análise Textual Discursiva – ATD, de Moraes e Galiazzi, inicialmente realizou-se a impregnação do material produzido pelos sujeitos da pesquisa, para então proceder com a unitarização, a construção de categorias analíticas e a escrita de metatextos. As problematizações realizadas no decorrer da dissertação foram apontando compreensões sobre a importância da formação docente no coletivo, constituída pelos estudos e diálogos vivenciados pelos sujeitos envolvidos; a compreensão das amarras do sistema societário que interferem no trabalho docente, salientando a necessidade dos professores resgatarem, enquanto categoria, sua capacidade de luta, seu sentido de união e coletividade no trabalho, fortalecendo suas representatividades através dos sindicatos; a compreensão da profissão docente como interpelada pelas relações humanas, ao entrelaçar a construção do conhecimento aos sentimentos como afetividade, respeito, alegria e esperança, envolvidos nesse processo, estão, nesse sentido, os professores constituindo sua humana docência. A partir das análises realizadas, compreender-se que as vivências de estudo e formação na Roda dos Sentidos, proporcionaram momentos de avanços teóricos, realizados a partir de diálogos sobre o trabalho e o trabalho docente, potencializados pelos registros escritos e compartilhados nos encontros da Roda, possíveis a partir da construção do sentido de coletividade, compreendendo-se, assim, a importância dos elos afetivos na constituição docente.

Literatura para a infância e espaços educativos: a exploração didática do álbum narrativo no âmbito da Educação Pré-Escolar

Atualmente o álbum narrativo tem sido alvo de atenção crescente na literatura de especialidade, sendo realçada a sua mais-valia em contextos educativos diversificados, mormente na Educação Pré-Escolar, favorecendo o prazer de ler, aspetos bem vincados nas Orientações Curriculares para a Educação Pré-Escolar (OCEPE, 2016). No entendimento de que as práticas de leitura das crianças em contexto educativo se podem entrelaçar, de forma benéfica, com práticas educativas em contexto familiar, este estudo centra-se na exploração didática de álbuns narrativos, envolvendo a família. Procura-se, assim, responder à seguinte questão de investigação: «Qual o contributo da exploração didática regular de álbuns, envolvendo a família, no que respeita ao desenvolvimento do gosto pela leitura das crianças, no âmbito da Educação Pré-Escolar?». Face à questão colocada, estabelecemos os seguintes objetivos de investigação: i) compreender se o envolvimento da família em atividades de leitura pode motivar as crianças para a mesma; ii) analisar de que modo a exploração didática de álbuns narrativos, no jardim de infância, pode contribuir para motivar as crianças para a leitura; iii) promover momentos lúdicos de contacto com álbuns.

Produção de biomassa e composição química de adubos verdes cultivados no Vale do Ribeira

The contribution of green manure to soil improvement and crop production depends primarily on biomass production and its chemical composition, which vary depending on the species, region and growing season. The aim of this research was to evaluate the chemical composition of biomass produced by green manures in Vale do Ribeira, São Paulo, Brazil. In order to develop this research, was carried an experiment in Pariquera-Acu, in 2006/2007, in completely randomized blocks design with four treatments (three green manure and spontaneous vegetation) and five replications. At 30, 60, 90 and 120 after sowing samples were collected in 1m(2) of the shoots and determined fresh and dry, and chemical composition biomass. Sunhemp, pigeon pea and mucuna produced, in decreasing order, the largest quantities of biomass and were more efficient than the spontaneous vegetation. The biomass produced by green manure had higher quality than that produced by spontaneous vegetation. Sunhemp and pigeon pea have a higher proportion of dry matter in stems which have low N, high C/N and L/N ratio, variables indicating slow decomposition of residues. The analysis of dry matter partitioned to better indication of the chemical composition of the residues and the prevision of the availability of nutrients in the soil.
