O Litoral e a metrópole dinâmica imobiliária, turismo e expansão urbana na região metropolitana de Natal-RN

The metropolitan regions of Northeast Brazil are being gradually included in a scenario of international investments, which are motivated by the restructuring of both touristic and real-estate sectors. The new capital, real-estate developers and space configurations that result from this process indicate the need for the creation and implementation of public tools which should, at least, allow the mitigation of the urban impacts and environmental losses resulting from this situation. The effects on landscape and on the socio-spatial configuration result from the intensification caused by the dynamism of the "real estate-tourism" sector. There is a regional integration as an expression of the urban expansion of the metropolitan area of Natal. This study investigates the uniqueness of the restructuring and territorial integration of coastal areas and the strategies of the circuit of capital accumulation formed by linking the real estate to tourism. It is intended to increase the understanding about the strategies of tourism, real estate and public policy agents involved in this territorial reconfiguration and in the fund-raising needed for the investments, to understand the existing social and environmental effects and their future trends and also to understand the forms of spatial production as results from the practices of approaching the land transformation and the tourism valorization of the landscape, in a synchronous manner, first in the Northeast region and, as a focal study, in the Metropolitan Area of Natal. Likewise, it is intended to apprehend the current processes of metropolization of the eastern coast of Rio Grande do Norte, in addition to indicate its physical-territorial transformation and the types of projects/developments promoted by the market in the recent period. Based upon analysis undertaken for the Metropolitan Region of Natal RN, this piece of work presents some considerations on possible legal instruments that can be adjusted to the municipalities which are experiencing the impact of this peculiar and recent phenomenon in the region, caused by the arrival of the real estate-touristic capital. It is also intended to point out basic proposals to the forms of public intervention, in a speculative way, starting from a Metropolitan Planning project within a medium and long term

Entre serras e sertões A(s) (trans)formaç(ões) de centralidade(s) da Região Metropolitana do Cariri/CE

This study reviews the spatial configuration from the road network of an urban compound formed by the cities of Crato, Juazeiro do Norte and Barbalha (the Crajubar - core of the Cariri metropolitan region, in the State of Ceará, Brazil), in order to establish nexus (or relations) between different levels of accessibility and the formation/ transformation and specialization of centralities in local and metropolitan scales. Stemming from the Social Logic of Space theoretical and operational apparatus, the study explores modeling possibilities (with axial lines, segments and lines of continuity) which is then confronted to empirical observations concerning movement flows and land use, within a Geographic Information System database. At different scales of analysis, the results suggest evidences of continuity were found in the permanence of intra-urban centres and sub-centres within each town, whereas evidences of change pointed out to the formation of a new centrality of metropolitan magnitude in the neighbourhood referred to as the Triângulo, in the municipality of Juazeiro, where high levels of topological accessibility coincides with the appearance of new business buildings as well as with the emergence of urban equipment of a scale more adequate to meet a regional demand

Avaliação da ecotoxicidade de percolados em áreas de disposição de resíduos na região metropolitana de Natal/RN

Leachates are effluent produced by decomposition of solid waste, they have complex composition and can be highly toxic. Therefore such percolated liquid should be collected and treated properly to avoid environmental contamination of soil and of water bodies. The objective of this study was to evaluate the toxicity through ecotoxicological tests with Ceriodaphnia dubia (Cladocera - Crustacea) of percolated liquids generated in two different systems of municipal solid waste (MSW) disposal in the city of Natal/ RN: A Sanitary Landfill in the Metropolitan Region of Natal/ RN, and in a dump off area. Furthermore, it was evaluated the possible contamination of the underground water of the dump off area. Two monthly samples were taken at four points between the months of May/2009 and January/2010. The Point "A" corresponds to the end of the pond leachate treatment in ASRMN; The Point "B" corresponds to a containment pond at the dump. The Point "C" is an area near one of the cells of the dump off area where the leachate outcrops; The Point "D" stands for an underground water well at the area. The last point, called "E" was sampled only once and corresponds to the slurry produced by temporary accumulation of solid waste in the open area of the dump. The ecotoxicological tests, acute and chronic, followed the ABNT 13373/2005 rules, with some modifications. The samples were characterized by measuring the pH number, the dissolved oxygen (DO), the salinity, BOD5, COD, Cd, Cu, Pb, Cr, Fe, Mg, Ni, and Zn. At Point A, the average number of EC50-48h ranged between 1.0% and 2.77% (v/v), showing a high toxicity of the leachate to C.dubia in all months. To this point, positive correlations were found between the EC50- 48 with precipitation. Negative correlations were found between the EC50- 48h with salinity. At point B there was no response of the acute exposure of organisms to the test samples. At point C the EC50-48h ranged from 17.68% to 35.36% in just two months of the five ones analyzed, not correlated meaning. Point D, the EC50-48h level ranged between 12.31% and 71.27%, showed a negative correlation with, only, precipitation. Although it was observed toxicity of underground water in the Landfill Area, there was no evidence of water contamination by leachate, however, due to the toxic character of this water, additional tests should be conducted to confirm the quality of water that is used for human supply. At point E there was no acute toxicity. These results support the dangers of inappropriate disposal of MSW to water bodies due to the high toxicity of the leachate produced highlighting the necessity of places of safe confinement and a treatment system more effective to it

Flebotomíneos (Diptera: Psychodidae) em um sistema agroflorestal da Região Metropolitana de Natal, Rio Grande do Norte, Brasil

Sandflies stand out as important vectors of leishmaniasis. The females need to ingest blood meals, enabling them to transmit protozoa of the genus Leishmania, which may give rise to visceral leishmaniasis (VL) or American tegumentary leishmaniasis (ATL), in addition to transmitting other parasites. Leishmaniasis are important infirmities, distributed worldwide, whose infection results from the interaction of reservoir animals, the vector insect, parasitic protozoa and the healthy host. In the state of Rio Grande do Norte (RN), Brazil, these insects are important transmitters of VL, which usually presents in the most serious form. It occurs mainly in metropolitan areas, with the dog as its main reservoir and Lutzomyia longipalpis as the vector. ATL is most present in the highland areas of the state. In addition to hematophagia, engaged in by the females, both sexes need to ingest carbohydrates, which are essential to the sand flies energy requirements and may interfere in the development of Leishmania. The aim of this study was to determine the occurrence and abundance of sand flies in different environments on the farm belonging to the Empresa de Pesquisas Agropecuárias do RN (Institute of Agricultural Research of RN), in the municipality of Parnamirim, in order to relate this occurrence with climatological and biological references and eating habits. Three consecutive monthly collections were carried out with CDC traps in a fragment of the Atlantic Forest, in a residence, on a goat breeding farm and on cashew, dwarf and giant coconut, mango, banana, eucalyptus, acacia and bean plantations. A total of 1241 sandflies from eight species (Lutzomyia evandroi, Lutzomyia longipalpis, Lutzomyia shannoni, Lutzomyia sordellii Lutzomyia walkeri, Lutzomyia wellcomei, Lutzomyia whitmani, and Lutzomyia intermedia) were collected, most in the forest environment. L. longipalpis, the main VL transmitter, was confirmed as a species adapted to anthropic environments, whereas others such as L. wellcomei, the vector of ATL, occurred predominantly in forests. Carbohydrate characterization of the sand flies and plants of the region demonstrated that a number of exotic plants such as hay and eucalyptus may play some role in the adaptation of these species to modified environments. Breeding in laboratory showed a mean biological cycle of 53.5 days from egg to adulthood for L. shannoni and the possibility of diapause behavior in L. wellcomei. This study serves as a source of information that may contribute to the epidemiological vigilance of tegumentary and visceral leishmaniasis in the state, given that it analyzes the bioecology of transmitting species, as well as their potential to adapt to new environments

Mercado de trabalho, ocupações e rendimentos: a Região Metropolitana de Natal na década de 1990

The aim of this study is the labour market at Natal Metropolitan Region with emphasis in occupations and incomes that took place at the nineties. The definition of its chronological boundaries passed by verification of existence of evident socio-spatial impacts for output, occupation and income in national economy, with rebounds in all national territory, conditioned by institutional and socio-economical transformations which marked Brazilian insertion to capital flows and commodities globalization movement that took place at the cited decade. It has been shown that such impacts did not distributed themselves equally between diverse spatial levels (great regions, federate unities, municipalities) because of historical specificities in each place in terms of output structures and organization of distinct social agents. Having as its basis the Marxist perspective, it tackled theoretically occupations and incomes, transformations in labour universe occurred at world level, mainly in most urbanized areas, and following that to focus changes occurred in Brazilian society related to the search for competitive insertion in global economy during the period regarded. Special attention was gave to Natal Metropolitan Region, because it was historically a concentration area for investments, productive structure, people, occupations and incomes generated/appropriated in Rio Grande do Norte State. The basic data sources for research were the demographic Census (micro data) made by the Instituto Brasileiro de Geografia e Estatística (IBGE) intending to present the structure and the labour market dynamics, having as basis: 1) traditional indicators about labour market; 2) sectors of economic activities and 3) social positions and classes segments. One of the purposes is the demonstration that occupations and incomes keep relation with the restructuring which occurred in each specific sector during the period. Other purpose is to make explicit the factors which bear the participation of distinct segments in production or service execution that make possible the different participation in income distribution. Results are revealing the increasin precariousness in labour market, enlargement of occupations in tertiary sector and greater concentration of average incomes in the social segments which were owners of the greatest capital allowances between residents in Natal Metropolitan Region during the nineties

Efeitos do ethephon sobre a produção da uva 'Niagara Rosada' (Vitis labrusca L.), produzida na entressafra na região de Jales-SP

A produção de 'Niagara Rosada' na entressafra, embora sendo uma excelente opção para os viticultores de Jales-SP, é problemática devido à dificuldade de emissão e desenvolvimento das brotações após a poda, realizada nos meses de ocorrência de temperaturas inferiores a 10ºC, o que tem causado pequenas produções e desestímulo entre os viticultores. Visando a solucionar este problema, foram conduzidos seis experimentos nos anos de 2001 e 2002, cujo objetivo foi verificar o efeito do ethephon aplicado antes da poda sobre o número de cachos, a produção e a qualidade da uva. Foram testadas as doses 0; 3; 6 e 9L.ha-1 de ethephon aplicado via foliar. Concluiu-se que o uso de ethephon proporcionou aumento do número de cachos e da produtividade de 'Niagara Rosada', especialmente quando da ocorrência de condições climáticas desfavoráveis e com satisfatório grau de enfolhamento. A utilização de ethephon na dose de 9L.ha-1 proporcionou aumento da produtividade da uva 'Niagara Rosada' na entressafra.

Produtividade e qualidade dos frutos da laranjeira 'Pêra' clone IAC em 16 porta-enxertos na região de Bebedouro-SP

Avaliou-se a influência de 16 porta-enxertos na produtividade, nas características físicas e químicas (sólidos solúveis totais-°Brix; acidez; ratio; porcentagem de suco; índice tecnológico e tamanho dos frutos) dos frutos da laranjeira 'Pêra' [Citrus sinensis (L.) Osbeck] e na incidência e severidade da clorose variegada dos citros (CVC). O plantio do experimento foi realizado em julho de 1993, com espaçamento de 6,0 m entre linhas e 3,5 m entre plantas (476 plantas/ha). O experimento foi conduzido sem irrigação. O delineamento experimental foi em blocos ao acaso, duas plantas por parcela, três repetições e 16 tratamentos, constituídos pelas seguintes cultivares porta-enxertos: tangerineira 'Sun Chu Sha Kat' (Citrus reticulata Blanco), tangerineira 'Pectinífera' (C. reticulata), 'Shekwasha' (C. depressa Hayata), tangerineira 'Pectinífera/Shekwasha' (C. depressa Hayata), tangerineira 'Batangas' (C. reticulata), tangerineira 'Oneco' (C. reticulata), citrangor [citrange (Poncirus trifoliata Raf. x C. sinensis) x C. sinensis], citrandarin [C.sunki hort. Ex Tanaka) x Poncirus trifoliata (L.) Raf. cv. English, tangerineira 'Sunki' (C. sunki), tangerineira 'Suen-Kat' (C. sunki), tangerineira 'Nasnaran' (C. amblycarpa Ochse), tangerineira 'Venezuela' (C. reticulata), tangerineira Heen Naran (C. lycopersicaeformis hort. ex Tan. ), limoeiro 'Cravo' (C. limonia Osbeck) x tangerineira 'Cleópatra' (C. reshni hort ex Tanaka), limoeiro 'Cravo' (C. limonia), tangerineira 'Cleópatra' (C. reshni). A intensidade da clorose variegada dos citros variou em função dos porta-enxertos e não se relacionou com a produção de frutos até a quarta safra. Os porta-enxertos estudados, com exceção da tangerineira Nasnaran, proporcionaram qualidade e produções iniciais de frutos similares aos do limoeiro 'Cravo'.

Brincar, atividade humana e ferramenta pedagógica no contexto escolar da região metropolitana de natal

This thesis talks about the use of guided educational tools in play and playful in public schools in the Metropolitan Region of Natal (MRN), contributing to the teaching and students learning of basic education in the contents of portuguese and mathematics. We assume that the play is an activity / human need and therefore implies the proper development of children in physical, psychological, biological, cultural, social and historical aspects. We consider the mediation exercised by the teacher in the classroom, and the affection existing between teacher and student, sine qua non terms, so that the truth and fact of the process of teaching and learning occur. Thus, theoretically collaborated Paulo Freire, with his dialogical vision; Lev S. Vygotsky says that we learn and why we develop; Lev S. Vygotsky that states that we learn and for that we develop ourselves; Pierre Bourdieu and the concept of habitus, as something embedded and therefore procedural, and the cultural capital that needs to be fed and (re)meaning at school; Luiz Pereira, Bernard Lahire, Gilles Brougère and others brought their theoretical contributions. The empirical field of research was composed by the Municipal School Professor Ulysses de Góis, located in the neighborhood of Nova Descoberta in Natal, and the Municipal School José Horacio de Góis, located in the community of Guanduba, in São Gonçalo do Amarante, municipalities of the Metropolitan Region of Natal (MRN). We used as methodology the collaborative-action-research as a possible of effective participation of the research subjects, imputing them a voice and performance in the process, and not considering them just observers. The results indicate the effectiveness of the pedagogical tools in play and playful to the learning of students, but that alone is not able to solve all the problems of the school, other referrals need to be secured, as the planning of the actions to be developed in the school and in the classroom, systematized pedagogical orienttion for faculty, family participation/involvement in the school life of students, among other actions that need to be weighted so that education fulfills its role and promote the emancipation of the subject, because in the freireana liberating perspective, "the reading of the world preced the lecture of the word"

Família, aluno e professor: as forças tipológicas da educação básica na região metropolitana de Natal

This work was developed in the research line: "The habitus of study: builder of a new reality in the basic education of metropolitan area Natal" which is being developed with the support of CAPES by the Centre for Education. Acts, especially the problem of academic performance of students in basic education of the public in the Metropolitan Region of Natal (RMN). Thus, the aim of this paper is to construct a typology of students in the 9th year of basic education, attending the public schools (state or municipal) of MRN, 2009, and assess, according to these profiles, what personal characteristics student and their families: economic, social and cultural capital as well as teaching practices create environments capable of favoring a good educational development as measured by the performance obtained in the assessments in mathematics and English language. The data used were provided through the microdata Brazil Exam 2009 held by INEP. We used the methods Grade of Membership (GoM) for construction of profiles relevance of students according to the characteristics already mentioned. With these profiles was verified, which were effectively generating good performance in school curriculum components evaluated. The findings indicate that students belonging to the profile considered good environment, able to achieve better school performance both in Portuguese as in Mathematics, compared to the extreme profiles and adverse deficit

Qualidade do gasto público em educação para os municípios da região metropolitana de Natal-2007

The aim of this thesis is to evaluate the quality of public spending on education for the municipalities of the Metropolitan Region of Natal (RMN) in 2009 by use of two theories: The Theory of Welfare (Welfare State) and the Public Choice Theory (TEP), both important to understand the relationship between education and economics. The study also uses principles of microeconomics and public sector economics to get a better idea of the role of education in economy and society. It describes the development of the educational policy in Brazil from 1988 to the Federal Constitution of 2010, following the major changes in basic education during each government. The characteristics of the RMN municipalities were illustrated with socioeconomic indicators, while educational indicators were used to characterize each municipality regarding education. The model used in this study was developed by Bertê, Brunet and Borges, the data was collected on the back of the School Census 2009 and the Brazil Exam 2009 and it was processed quantitavely in the Information System on Public Budgets in Education (SIOPE) by use of the statistical method called standardized score of the normal cumulative distribution function. The quality of public spending on education is the result of the relation between performance indicator ratio and expense ratio. For the qualitative analysis of results, the criteria of efficiency, efficacy and effectiveness were used. The study found that municipalities with higher expenses showed a worse quality of spending and failed to convert the expenditure incurred into performance, thus confirming ineffectiveness

Industrialização e emprego formal: uma análise para os municípios da região metropolitana do Cariri nos anos de 1990 e 2000

The Northeast has a record of fighting to reduce disparities. In late 1950, the state intervened through SUDENE, organizing and planning the promotion of development through industrialization. This study aims to identify the characteristics of the industrialization of the Northeast and evolution of formal employment in the metropolitan area of Cariri, located in the southern state of Ceará, in the case of the municipalities of Crato, Juazeiro do Norte and Barbalha (CRAJUBAR) in decades of 1990 and 2000. The assumption permeates the SUDENE with public policies to encourage the industry, causing profound changes in the cities studied. The results indicate that the Cariri since the 1960 has been benefiting the programs implemented by SUDENE. With the implementation of these programs, with in a set of circumstances based on local vocations and state policies, there was a spatial distribution industry, triggering a growth and development on the provision of formal jobs in the industrial sector

O Cariri cearense: da ocupação do território à institucionalização da região metropolitana do Cariri

Urbanization in their mearing simpler, the agglomeration of people, occurred from the time that the productive activities have to be based on trade. The first cities arose when the evolution of agriculture allowed the production and storage of surpluses. However, with industrialization was that urbanization becomes intense, according to Singer (1987), the industrial revolution was to stage, from the beginning, the urban area. It requires, in its proximity, the presence of a large number of workers. With respect to the Cariri cearense, the occupation of its territory is associated with the movement of agricultural surpluses produced and reproduced under the hegemony of merchant capital and due to the development of extensive cattle that promoted the territorial occupation of Ceará. From the 1960s, the region has undergone changes in its productive structure due to industrial planning policies of the government of Ceará. However it was in the 1990s that the region itself as economic and urban polo because policies to attract investments from the state government of Ceará. This policy led to boosting trade and services marking the predominance of tertiary activities in the region, especially the retail, wholesale , medical services and education. Investments also consolidated the industrial park area making it diverse, especially the footwear industries, mining, non-metallic minerals, transport equipment, pharmaceutical chemical, food and beverages, rubber and leather and construction. Thus, the aim of this study was to review the region of Cariri cearense occupation of its territory institutionalizing its metropolitan region, to understand what factors influenced the Cariri cearense become an important area in urban and economic terms in the interior of Ceará. In order to develop this research in that refers to the methodological perspective, research is guided by bibliographic studies and also makes use of secondary data analysis (population, GDP, urbanization rate, employment) of the main databases the country, as IBGE, IPEADATA and RAIS - MTE

Desenvolvimento de frutos de Longan (Dimocarpus longan lour) na região de Jaboticabal-SP

O presente estudo teve por objetivo avaliar o desenvolvimento de frutos de plantas de longan (Dimocarpus longan Lour) na região de Jaboticabal, estabelecendo-se, portanto, a curva de crescimento dos frutos. As avaliações realizadas foram semanais, consistindo em medições do diâmetro longitudinal e transversal dos frutos marcados, a partir do momento da formação da polpa. Quinzenalmente, realizaram-se avaliações de características físicas: massa de fruto (g), casca (g), polpa (g) semente (g), e químicas: acidez titulável (AT), sólidos solúveis (SS), ácido ascórbico (AA) e ratio (SS/AT). Com os resultados obtidos, pode-se concluir que o ciclo de frutificação da Longan na região é entre 120 e 130 dias após antese, período em que o fruto estaria apto para o consumo. A curva do desenvolvimento dos frutos segue um padrão sigmoidal simples. Com relação aos atributos físicos e químicos, constatou-se que a planta 6 apresentou os melhores resultados, podendo ser recomendada como planta-matriz.
