Esta disertación aborda la lectura e interpretación de las obras Grande Sertão: Veredas, de João Guimarães Rosa y Del Ingenioso Hidalgo Don Quijote de la Mancha, de Miguel de Cervantes Y Saavedra, enfocando aspectos relacionados a las acciones de los caballeros andantes Riobaldo, el jagunço de Rosa y don Quijote, el Caballero de Cervantes, las cuales tuvieron decisiva influencia en su estado de espíritu melancólico. En la base teórica de este trabajo, investigamos la noción de melancolía, sistematizada por Kristeva y Freud, así como los estudios de la melancolía y de la alegoría a la luz del pensamiento de Walter Benjamin. Este estudio se concentra, sobre todo, en el aspecto que denominamos de alegoría de la circularidad, que permea las dos novelas, mientras expresión de cosas inacabadas que sugiere la idea de movimientos de espiralamento. Se percibió que lo retorno es consagrado en ambas las obras, es decir diferente el igual, dicho que consagra la diferencia y cierra las puertas para la repetición literal de sentido. En tal comprensión, ese movimiento no puede ser concebido como metáfora del mismo, pues sugiere la travesía que permanece inacabada y tortuosa, su estatuto de repetición no se honda en el encuentro de las dos puntas del ovillo, porque gira en el interior de aquello que repite como diferencia y liberación

This master thesis aimed to investigate how the power relations operating in the tourism social processes, have shaped the urbanization of Ponta Negra district, Natal, Rio Grande do Norte - RN. The study assumes that the production of space is the result of global phenomena individualized by local forces a process of glocalization. The method used was the case study. It used primary and secondary data and information were treated using the technique of content analysis. The urbanization of Ponta Negra is inserted in the context of global process triggered in the 1970s. The Park of Dunas and Costeira Highway (PD/VC) urbanization project marks the beginning of the Tourisms since 1979. The period in focus was 1979 to 2009. The tourism was dived into four major sections time: tourism in Natal before the Coastal Highway (1939-1979); Project Parque das Dunas / Coastal Highway to the first boom in domestic tourism (1979 - 1990); the internationalization of tourism (1991-2000) and, of first "boom" to "decline" of international tourism (2001-2009). Based on the historical evolution of the tourism were elected three different social processes, able to demonstrate how relations of social forces brought in space act on them and help shape the process of urbanization of the neighborhood in question: The removal of beach hut , the soccer field Botafogo Football Club and the skyscrapers . Finally, it should summarize the research identified interests and conflicts among the actors that form the thrust of spatial transformations: cultural conflicts resulting from the imposition of social practices that differ from the taste of native; clashes between different groups that reflect the duality between use value and exchange value; and interests in land values. In addition, demonstrated that the social relations that involve the production of the area are stimulated by deep-seated societal processes historically and camouflaged by market relations and a modern facade that the city has acquired in recent times; revealed that the actors are linked in networks to increase their influence and that this influence varies mainly according to economic and political power that they or their associates hold

With process urbanization process the Brazilian cities have been goin through, Natal/RN does not differ from the other ones, it has had a fast, inordinate and planned urbanization, but not applied, it has caused a high increase of social environmental problems. One of the worrying problems observed is the change in the coastal landscape, which has caused serious damage to the city‟s population, more specifically, of Ponta Negra beach neighborhood. For the geographical studies, the issue, concerning the occupation of the beaches that has been getting higher and higher in the last decades is extremely important because these, in addition to being used as homes in the new urban configuration, have incorporated new ways of environmental interference, without a simultaneous advance of knowledge which would be necessary for a more suitable and rational use of litoral spaces. Thus, the current assignment aimed to focus the coastal landscape of Ponta Negra Beach, in the city of Natal/RN, checking and analyzing the effects caused by anthropic and natural action, and the way it reflects in the quality of life of the resident, working population and of the frequenters as well as the landscape transformations in the area which is object of study, from 1970 through 2010. The methodology used followed to stages, the first concerned the theoretical work bibliographic surveying and composition; and second one the empirical work marking of the environmental characterization and application of the questionnaires. So, we can measure that Ponta Negra, is very susceptible to environmental changes, the ones caused by the natural dynamics of the beach, as well as the human actions (society) in this really fragile and mutable space, so it needs, a more profound systematic study about the coastal landscape. In order to reach a minimization of the change of the landscapes in the coastal zones there must be an integrated management of the environments, based on the planning of actions and territorial reordination of the occupations of these so important spaces, environmentally, as well as socioeconomically. Whereas, only this way, we will have a sustentable development and a suitable use of that space

The broach presented in this dissertation, linked to post graduate Geography´s of the Universidade Federal do Rio Grande do Norte - UFRN, more exactly about the research group entitled interdisciplinary studies unit on space and housing built . The research developed through this study has this central theme on vertical grounding of the construction in the neighborhood of ponta negra in Natal, Rio Grande do Norte. Realizing this momentum as a way of accumulation of capital in city. Rio Grande do Norte´s city. During the 2000 s , the neighborhood of Ponta Negra went through an intense process of vertical integration of its ground, Provided by many factor of conditions created from new economic, political and social functions which start to be outlined mainly from the tourism development in this neighborhood since the 80´s decade. The Tourism development and the landing planning of the ponta negra´s neighborhood promoted for the government by using order to police the city´s urbanization, beyond the sense of the civilian building actors. They enabled this neighborhood to become propitious to the real estate investments. Many ventures were built before the year of 2010 while another are on building, which, over the years, changed the sociospatyal dinamics of the neighborhood. Considering the urban space is socially built, product and condition for the reproductive process of the capitalist society, the goal of this research is to investigate the verticalization of the ground, for capital reproduction purposes. This research aims to analyze the vertical this quarter through the theory of social production of space by Henri Lefebvre. The Methodology adopted pervades for secondary and primary research, compound for bibliographic research, documentary, journal, magazines, camp research and interview, to reach the best way to analyse the dynamics of the refered neighborhood

Cette étude a été fondée sur la reconaissance, la description et l'analyse du circuit spatial de la production de l activité des fabriques des casquettes dans la région du Seridó Potiguar. L activité des fabriques des casquettes est située dans les villes de Caicó, Serra Negra do Norte e São José do Seridó, qui forment le pôle de fabriques de casquettes, composé de soixante-quatre (64) unités de fabrication, le deuxième plus grand producteur de casquettes au Brésil. Dans la condition de base géographique, l'opérationnalisation du concept de circuits spatiales de la production a été essentielle à la compréhension de l'utilisation du territoire et de l'indivisibilité de l'espace, du fournisseur de matières premières au consommateur final, comprenant les étapes des matières premières, la main-d'oeuvre, le stockage, les transports, le commerce et la consommation dans la période actuelle, dans laquelle les instances de la production, la circulation, la distribution et de la consommation sont spatialement diffus. Sur la base de l'identification et de la localisation de ces étapes et des principaux acteurs impliqués dans la activité des fabriques de casquettes, une configuration de circuit spatial de la production a été élaborée, en s'interprétant l'utilisation des territoires par les instances productives. L'interprétation des étapes de production a identifié que les entreprises liées à l'Association Seridoense des Fabricants de Casquettes agissent plus efficacement sur le territoire que celles nonassociées, alors que toujours elles investissent dans des nouveaux équipements, en augmentant sa puissance technique pour se renforcer avant un marché si compétitif comme celui des casquettes. En examinant la contribution de la fabrication des casquettes à l'utilisation actuelle des territoires de la coupe, nous avons appris que les activités complémentaires et des matières premiéres nécessaires à sa réalisation se trouvent dans leur environnement géographique. Ainsi, la proximité spatiale entre les étapes de la fabrication des casquettes fait entrevoir la matérialité du territoire, conférée dans la coexistence des techniques passées et présentes, et l'ensemble des actions effectuées par un certain nombre de travailleurs sociaux qui collaborent à la création du circuit spatial de la production de l activité des fabriques des casquettes. Cette étude a confirmé que les fabriques des casquettes sont organisées sous la forme de cellules de production, continues ou discontinues, dont les équipements et les machines à coudre industrielles obéissent à la logique d'une production de plus en plus standardisée. Ce circuit spatial de la production contribue à l'utilisation actuelle des territoires de Caicó, Serra Negra do Norte et de São José do Seridó car il amplifie le mouvement du commerce et des relations entre les lieux, à travers la dynamique des flux des personnes, des biens et des produits, en constante circulation, guidées par la division du travail entre les étapes productives

This paper aims to analyse and discuss the labour in hospitality industry, specially the hospitality trade in Ponta Negra Natal/RN, Brazil, since the tourism has increased in the city, by investigating if the tourism field is suitable for public politics programs and labour qualification. The choice for Ponta Negra is because it has become the focus of tourism development in Natal. The research was developed by using qualitative approach of investigation, by means of some procedures such as: bibliographic and empirical researches, by using questionnaires with workers and recruiting personnel of hotels, always following a theory and a reflexive descriptive attitude. This dissertation involves eight chapters: Neoliberalism and labour; Economical and spatial restructuring of Rio Grande do Norte; Public politics concerning tourism area; Tourism, graduation and qualification in hospitality industry; Qualification for tourism hospitality; Hotels: territorialization and unterritorialization; Social qualification reality of people involved in hospitality activities in Ponta Negra, Natal/RN, Brazil; and Final considerations and recommendations. Therefore, this paper intends to contribute for understanding professional qualification in hospitality trade, confronting the needs that the service requires, and mainly, in the tourism sector, which is increasing in our city, Natal

This dissertation includes the monitoring of coastal environmental dynamics at three points distinct from Ponta Negra beach, located on the South Coast of Natal, capital of Rio Grande do Norte, in the period June 2012 to May, 2013. For this, the following hypotheses were developed: Which actors morphodynamic and/or anthropogenic responsible for the changes in the study area? And yet, the configuration of the morphodynamic state of the beach, dissipative, reflective or intermediate? Faced with these questions , studies on the beach environment has its relevance as they may clarify the risks and responsibilities of anthropogenic intervention and also assist managers in more targeted action regarding the protection of praiais systems, since once committed, it is very difficult recover the environmental framework of the area, being greatly more feasible the development of multidisciplinary work plans that can guide human actions possible in search of an understanding to the harmonious interaction between society and the beach system. Its main goal is the understanding of the processes of coastal dynamics, methodological procedures that supported the implementation of this research were based on the object of study related literature associated with the collection of data resulting from beach profiles made monthly in spring tides (full moon), the hydrodynamic data and statistical quantification data (%) and size classification of sediment sediment after laboratory analysis. The results obtained from annual comparative tables of beach profiles, associated sedimentological analysis, indicated a positive sediment budget, tending to equilibrium for Point 01 and Point 02 negative. Have to Step 03 were added to the hydrodynamic data, which allowed also on a comparative framework, the perception of a depositional dynamics, with a tendency to decrease the accumulation of material at the end of the annual cycle. These data also allowed for the point 03, the calculation of the volume of material transported by the longshore current was around 104.280 m³/m, plus the Dean parameter which established a morphological state of the dissipative beach with specific prevalences for point 03. Thus, given the results presented in this work in a timely monitoring of coastal dynamics is expected that managers and public authorities can articulate multidisciplinary work plans, always aiming actions that seek understanding and effective commitment to the recovery of the harmonious interaction between society and Ponta Negra beach environment

This dissertation is about low-income rental housing vilas in the South Zone in the city of Natal. Vilas are a string of houses, built privately in an urban plot of land, usually a backyard, facing a narrow street beco. This type of housing is originated in the 19th century in the Brazilian scenario. In Natal, this has become more popular since the late 1960s. This study is aimed at analyzing the urban integration of the vilas, considering that these house a low income population, vis à vis the speedy development of Natal s most economically dynamic area. The study starts with a discussion of the production of space, taking into consideration categories such as use value, exchange value, commodity and land rent. Field work was undertaken through structured interviews with dwellers of vilas in Nova Descoberta and Ponta Negra neighbourhoods. Owners of vilas were also interviewed. Data collected indicated worrisome housing conditions. Vilas, in the areas researched, are increasingly becoming unwelcome, constituting guetos in a place where landscape is changing rapidly. Gentrification is fast under way, first because of rise in rent and taxes; second because of general rise in living costs

A Sigatoka-negra (Mycosphaerella fijiensis) ameaça os bananais comerciais em todas as áreas produtoras do mundo e provoca danos quantitativos e qualitativos na produção, acarretando sérios prejuízos financeiros. Faz-se necessário o estudo da vulnerabilidade das plantas em diversos estádios de desenvolvimento e das condições climáticas favoráveis à ocorrência da doença. Objetivou-se com este trabalho desenvolver um modelo probabilístico baseado em funções polinomiais que represente o risco de ocorrência da Sigatokanegra em função da vulnerabilidade decorrente de fatores intrínsecos à planta e ao ambiente. Realizou-se um estudo de caso, em bananal comercial localizado em Jacupiranga, Vale do Ribeira, SP, considerando o monitoramento semanal do estado da evolução da doença, séries temporais de dados meteorológicos e dados de sensoriamento remoto. Foram gerados mapas georreferenciados do risco da Sigatoka-negra em diferentes épocas do ano. Um modelo para estimar a evolução da doença a partir de imagens de satélite foi obtido com coeficiente de determinação R² igual a 0,9. A metodologia foi desenvolvida para a detecção de épocas e locais que reúnem condições favoráveis à ocorrência da Sigatoka-negra e pode ser aplicada, com os devidos ajustes, em diferentes localidades, para avaliar o risco da ocorrência da doença em polos produtores de banana.

A mancha de mirotécio causada por Myrothecium roridum Tode ex Fr. foi observada em lavouras de algodão no sul do Maranhão, causando reduções de produtividade de até 60%. Os sintomas da doença são lesões necróticas, circulares, com estruturas salientes, os esporodóquios, de distribuição irregular. Foram observadas lesões nos pecíolos, brácteas, folhas e maçãs de algodoeiro cv. Deltapine Acala 90, Fibermax 966 e Sure Grow 821. O isolamento do fungo foi realizado em meio de cultura batata-dextrose-ágar (BDA). O teste de patogenicidade foi realizado em maçãs sadias, destacadas de algodoeiro cv. Fibermax 966, no estádio vegetativo R6, previamente desinfestadas. Foram testados 13 isolados de M. roridum, oito provenientes de algodão e cinco de soja. Avaliações das estruturas fúngicas foram realizadas com auxílio de microscópio óptico equipado com um micrômetro ocular. Os isolados causaram infecções em maçãs de algodão e destacou-se como mais agressivo o MA-75, proveniente de algodão, apresentando diâmetro médio de lesão de 1,3cm, aos sete DAI e 2,7cm aos 14 DAI. Todos os isolados formaram esporodóquios dispostos concenticamente em meio BDA. Os conídios são unicelulares, hialinos a oliváceos, abundantemente produzidos em massa verde-oliva a preta. Os conídios de isolados provenientes de algodão mediram, em média, 5,1µm x 1,5µm, e os obtidos de soja, 5,8µm x 1,5µm. Estes resultados relatam a ocorrência da mancha de mirotécio, causada por M. roridum, em lavouras comerciais de algodão no Brasil.

The objectives of this work were to determine the micelial growth curve of the pathogen and the sensitivity to some fungicides potencially efficient to disease control. The optimum temperature range for micelial growth of Phyllosticta sp, was between 25 and 27.5 degrees C. The maximum and minimum temperatures for micelial growth were 32.5 degrees C and 10 degrees C. Temperatures of 5 and 35 degrees C completely inhibited the growth of the isolates. Total inhibition of the micelial growth was observed with captan and mancozeb (1000 mg a.i./ml) and triadimenol (100 mg a.i./ml). Partial reduction of the micelial growth was observed with iprodione, methyl tiofanate and chlorothalonil until 1.000 mg/ml. The chemical control of PLS was studied in a commercial area of ginger ''Gigante'', in Morretes, PR, where 18 sprays were carried out, with a break of 7 to 10 days, from December to April. The highest reduction of the area under the disease progress curve standardized (AUDPCs) was observed with the spray of chlorothalonil. With the application of dithianon, cupper oxychloride, folpet, mancozeb and captan it was observed AUDPCs between 15.05 and 18.61 lesions/leaf. Iprodione, benomyl, triadimenol and methyl tiofanate did not control the disease (AUDPCs between 20.03 and 25.04 lesions/leaf). The AUDPCs in the check plot was 35.88 lesions/leaf. There was no significant difference of vigor and of ginger yield between fungicide treatments. The cupper oxichloride was phytotoxic to ginger.

Citrus blackfly, Aleurocanthus woglumi Ashby, is a serious pest of citrus culture and other economically important fruit crops. It is a present quarantine pest or A2 maximum alert restricting trades with other regions free of its presence. Since the frst occurrence of the citrus blackfly in Belem in 2001 its dissemination was quickly to other States and regions of citrus production in Brazil. As an exotic pest, basic knowledge is scarce in order to establish the appropriate management to the insect in Brazil. Thus, the aim of the present study was to provide information about important aspects of A. woglumi, such as: history and geographical distribution, bioecology, host plants, appropriate control methods, among others, in order to provide subsidies for futures researches about the citrus blackfly in Brazil.
