Tempo, memória e narrativa kaingang no oeste catarinense: a tradição kaingang e a proteção tutelar no contexto da transformação da paisagem na terra indígena Xapecó
Get PDFTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-Graduação em História, Florianópolis, 2015.Este estudo acerca dos Kaingang da Terra Indígena Xapecó orienta-se pelas relações estabelecidas do povo com o ambiente e seus desdobramentos, visa dessa forma apresentar os meandros da atuação da proteção tutelar no contexto da transformação da paisagem e as consequentes rupturas, impactos e/ou continuidades no modo de vida e no habitus social Kaingang. A temporalidade deste estudo conduziu-se a partir dos registros e descrições relacionadas aos Kaingang do século XVIII e alcança a contemporaneidade. Os encontros e desencontros dos Kaingang com não índios em terras meridionais foram registrados em descrições de cunho etnográfico e representam momentos decisivos na trajetória histórica do povo. Por outro lado, foi a partir dos oitocentos e, sobretudo, dos novecentos que a espacialização e a territorialidade Kaingang deslocaram-se visceralmente da condição de mobilidade para a de homo situs, impactando as relações do povo no tempo/espaço. A indigeneidade da paisagem marca as narrativas de história e memória dos Kaingang ressaltando a existência do tempo dos ?antigos? e do tempo de ?agora?. As reminiscências mnemônicas expressas entre silêncios, esquecimentos e lembranças descrevem os enredos das relações de contato e da proteção tutelar, bem como as instâncias constituintes do mundo Kaingang. As narrativas ressaltam o papel central do ?mato virgem? e do ?pinhalão? no modo de vida e no habitus social à medida que estes espaços são entendidos como elementos integrantes da tradição Kaingang. A tese elaborou e apresenta diversos produtos em história indígena e ambiental no que concerne a localização e a caracterização da TI Xapecó através de mapas e da perspectiva multi-temporal da composição da cobertura florestal. As sinuosidades da transformação do modo de vida e habitus social Kaingang e da paisagem da TI Xapecó são expressas nas múltiplas faces da proteção tutelar, que por meio do propulsor indigenismo brasileiro, possibilitou a grilagem, o esbulho e a espoliação dos índios do ?Chapecózinho? ao mesmo tempo em que a inserção da TI na lógica do desenvolvimento econômico. A ?marcha para a emancipação econômica? do Posto Indígena Xapecó a partir da gestão do patrimônio indígena percorreu momentos distintos e pautou-se na exploração das potencialidades naturais. O modelo de indigenismo rondoniano-varguista marcou um primeiro momento da proteção tutelar sendo procedido pelo indigenismo da FUNAI, que a despeito de seu início moralizante, permitiu à exaustiva exploração dos recursos florestais e inseriu as terrasindígenas no sul do Brasil no contexto do nacional-desenvolvimentismo brasileiro. A exploração da madeira se encerrou na TI Xapecó e a proteção tutelar na figura do chefe de Posto perdeu definitivamente qualquer status de poder centralizador à medida que o protagonismo Kaingang passou a conduzir as práticas políticas e socioeconômicas locais.Abstract : This study about the Kaingang of the Indigenous Land Xapecó is guided by the established relationships of the people with the environment and its consequences, aims to present the intricacies of the tutelary protection action in the context of the landscape transformation and the resulting disruptions, impacts and/or continuities in the way of the Kaingang life and social habitus. The temporality of this study was conducted from the records and descriptions related to the Kaingang of the eighteenth century and reach the contemporary. The meetings and missings of the Kaingang with non-Indians in southern lands were recorded in ethnographic descriptions and represent defining moments in the historical trajectory of the people. On the other hand, was from eight hundred and, especially, the nine hundreds that the Kaingang spatiality and the territoriality viscerally moved up from de mobility condition for the homo situs, impacting the relationships of the people in the time/space. The indigeneity of the landscape mark the narratives of memory and history of Kaingang highlighting the existence of time the "old" and the time of "now." The mnemonic reminiscences expressed between silences, omissions and memories describe the plots of contact relations and of tutelary protection, as well as the constituent bodies of the Kaingang world. The narratives emphasize the central role of the "virgin forest" and the "Pinhalão" on the way of life and social habitus as these spaces are seen as integral components of Kaingang tradition. The thesis developed and presents several products in indigenous and environmental history regarding the location and characterization of Indigenous Land Xapecó through maps and multi-temporal perspective of the composition of the forest cover. The sinuosity of the transformation of the Kaingang way of life and social habitus and the Indigenous Land Xapecó landscape are expressed in the multiple facets of tutelary protection, which through the Brazilian indigenous propellant movement, allowed the illegal occupation, the dispossession and the theft of the "Chapecozinho" Indians while the integration of Indigenous Land in the logic of economic development. The "march toward economic emancipation" of the Indian Post Xapecó from the management of Indian heritage come different times and was marked on the exploitation of natural potential. The model rondonian-varguist of indianism scored a first moment of tutelary protection being undertaken by the FUNAI indianism, which despite its moralizing beginning, allowed the plundering of forest resources and entered indigenous landsin southern Brazil in the context of the Brazilian national-developmentalism. The logging ended in Indigenous Land Xapecó and the tutelary protection in the image of the post headman definitely lost any power status as the Kaingang role began to conduct local political and socio-economic practices
Na alvorada de um sport : o remo na ilha de Santa Catarina
Get PDFDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-graduação em História, Florianópolis, 2013Em Florianópolis, a primeira Sociedade de Regatas organizada, meados do século XIX, contaria com a participação dos Coronéis da Marinha e da Escola de Menores e Marinheiros da Canhoneira. Na virada do século, a fundação do Clube 29 de Abril permitiria que as atividades relacionadas ao Remo fossem oferecidas a todos que se associassem ao Clube. No entanto, somente entre os anos de 1915 e 1918, com a fundação dos Clubes Náuticos Riachuelo e Martinelli e o Clube de Regatas Aldo Luz, é que o Remo adquiriria sua característica de prática física salutar ao homem. Entre as transformações urbanas que ocorriam em Florianópolis, que visavam higienizar a cidade e dar ares modernos aos seus habitantes, o Remo e sua prática seriam incentivados. Intelectuais, imprensa e sociedade se intrincariam com a prática náutica, pois durante as regatas os remadores tornar-se-iam verdadeiros heróis ao exibirem sua força, beleza e disciplina. Assim, esboçar a presença do Remo e as suas relações com um corpo, a cidade e uma intelectualidade na capital catarinense, do início do século XX, é o principal objetivo desta dissertação. Abstract: In Florianópolis, the first Society of Regattas organized, mid-nineteenth century, would include the participation of the colonels Navy and School of Minors Marines and the Gunboat. At the turn of the century, the foundation of the Clube 29 de Abril, activities related with the Rowing were offered to all who associate the Clube. However, only between the years 1915 and 1918, with the founding of the Clubes Náuticos Riachuelo and Martinelli and Clube Regata Aldo Luz, the rowing is that acquire their characteristic physical practice and healthy man. Among the urban transformations that occurred in Florianópolis, which aimed to sanitize and give the city its modern air inhabitants, Rowing and his practice would be encouraged. Intellectuals, media and society had spoken of nautical practice, rowers would become real heroes to showcase their strength, beauty and discipline. Sketch the presence of Remo and their relationships with one body, the city and Intellectuality in the capital of Santa Catarina, in the early twentieth century, is the main objective of this work
Grau de espessamento da carina brônquica e de quantidade de muco na traqueia como indicador de inflamação das vias respiratórias inferiores em equinos
Get PDFOrientação : João Rodrigues ; co-orientação : Manuel PequitoO tema abordado neste trabalho incide sobre grau de espessamento da carina brônquica e de quantidade de muco na traqueia como indicador de inflamação das vias respiratórias inferiores em equinos. Estas alterações são observadas em doenças respiratórias como a doença inflamatória das vias aéreas e a doença obstrutiva recorrente. Estas doenças afectam um grande número de cavalos, e os indicadores foram medidos através de uma endoscopia das vias aéreas.
Uma vez que a relevância da medição de parâmetros como o grau de espessamento da carina brônquica e a quantidade de muco na traqueia estão pouco estudados, o objetivo deste trabalho é contribuir para um melhor esclarecimento sobre o mesmo, bem como, determinar esta mesma relevância.
Foram realizadas endoscopias e lavagens broncoalveolares a 253 animais, nas quais foram estabelecidos scores de muco na traqueia e na carina brônquica e avaliado o grau de espessamento da carina brônquica. Através de testes estatísticos foram avaliadas as relações entre estes mesmos scores e as percentagens das células resultantes da citologia da lavagem broncoalveolar. Outro teste efetuado foi a avaliação da relação entre a idade e a quantidade de muco.
Os resultados do trabalho comprovaram que a utilização de escalas de quantidade de muco e do espessamento da carina brônquica não é um indicador fiável de inflamação das vias aéreas inferiores dos equinos. No entanto, a avaliação do espessamento da carina brônquica é fiável quando avaliamos esta quanto à presença ou não de espessamento. Outra conclusão retirada deste estudo é que a idade do animal é proporcional à quantidade de muco presente na traqueia.The issue addressed in this paper focuses on the degree of thickening of the bronchial carina and amount of mucus in the trachea as an indicator of inflammation of the lower respiratory tract in horses. These changes are seen in respiratory diseases such as inflammatory airway disease and recurrent obstructive disease. These diseases affect a large number of horses,
and the indicators were measured using an endoscopy of the airways.
Since the relevance of the measurement of parameters such as the degree of thickening
of the bronchial carina and the amount of mucus in the trachea are understudied, the aim of this
work is to contribute to a better clarification on these topics, as well as determine this
relevance’s level.
Endoscopies and bronchoalveolar lavages were performed on 253 animals, in which were established scores regarding presence of mucus in the trachea and bronchial carina, and
was also assessed the degree of thickening of the bronchial carina. Through the use of statistical
tests it was possible to assess the relation between the established scores, as well as the
percentages of cells resulting from the cytology of bronchoalveolar lavage. It was also performed a test to assess the relation between age and the amount of mucus.
The findings demonstrate that the use of scales for the amount of mucus and the
thickening of the bronchial carina is not a reliable indicator of inflammation of the lower airways of horses. Nevertheless, the assessment of the thickening of the bronchial carina is
reliable when it is assessed regarding the presence or absence of thickening. Another conclusion
to be drawn from this study is that the age of the animal is proportional to the amount of mucus
existing in the trachea

Protibia and tarsus with occlusal inner surface flattened; tarsus one-segmented, immovable; pretarsal claw single, minute, triangular. Meso- and metacoxae partially recessed into thorax. Meso- and metafemora with row of short, brown spines on anterior margin. Meso- and metatibiae with ventrolateral, ventromedial, dorsolateral, and dorsomedial rows of stout brownish spines; meso- and metatibiae with two transverse rows of spines distally, one each on lateral and mesal margins. Meso- and metatibiae and metatarsus with long, pale swimming hairs, hairs profuse on metatibia and - tarsus. Meso- and metapretarsi with paired claws slender, gently curved, with minute basal tooth. Leg measurements as follows: fore leg, femur 2.05, tibia 1.20, tarsus 0.53; middle leg, femur 1.90, tibia 1.35, tarsomeres 1–3, 0.10, 0.30, 0.35; hind leg, femur 2.65, tibia 2.70, tarsomeres 1–3, 0.15, 0.65, 0.65. Abdomen. Dorsally with lateral margins of terga III–VII exposed; terga III–VI dark-brown anteriorly, light-brown posteriorly (Fig. 2A); marginal row of short yellow setae, and group of trichobothria near posterolateral corners (collapsed in holotype). Lateral margin of abdomen serrated, tergum V with 18 teeth. Posterolateral corners of II–V right angled, not spinose, VI acute. Sterna mostly brown; elongate golden setae generally dispersed, concentrated near midline (Fig. 2D); sternum II with sinuous row of elongate golden setae. Tergum VI symmetrical. Subgenital plate broad, almost as wide as long, width 0.98 × length; length at midline 1.38; maximum width 1.35; lateral margin with tuft of elongate golden setae at mid-length (collapsed in holotype), ending in a narrowly rounded apex; laterosternite VII tapered at apex (Fig. 2D). Male – hindwing brachypterous. Paratypes (n = 2), length 8.05–8.13; maximum width 5.60–5.65. Similar to female in general structure and coloration, except as follows: Mediotergite VI with accessory genitalic process narrowly rounded; posterior margin without notch on left side. Mediotergite VII posterior margin forming two pairs of small rounded lobes, one medial and one lateral; mesal margin of laterotergite VII convex (Fig. 6A). Lateral lobe of tergum VIII with lateral margin straight in anterior half; left medial lobe angled laterally and truncate at apex, with posteromesal corner narrowly rounded; right medial lobe twisted in distal third (Fig. 6B). Diagnosis. Body length 7.82–8.13, body width 5.60–5.70. The shagreened area of the propleuron is not extended posteriorly along the lateral margin (Fig. 2B). The mesosternal carina has the median ridge straight, and the fossa is deflexed ventrad, oval, poorly crenulated at the lateral margins, and contains short golden hairs inside the rim and on the anterior projection; the posterior margin is excavated in lateral view after the fossa (Figs. 2C, E). Male mediotergite VII has the posterior margin with two pairs of small rounded lobes, one medial and one lateral (Fig. 6A). The female subgenital plate is broad, ending in a narrowly rounded apex (Fig. 2D). Comparative notes. This species has a propleuron shagreened pattern similar to that of L. flavescens n. sp., where in both species the shagreened area is not extended posteriorly along the lateral margin. However, these two species are easily separated by the shapes of the meso- and metasternal carinae. In L. amazonensis, the fossa of the meso- and metasternal carinae are oval and developed (Fig. 2C, 2E), whereas in L. flavescens these two carinae are narrow and, specifically for the metasternal carina, the fossa is indistinct (Figs. 5C, E); in addition, they differ in coloration of the body and the shapes of male abdominal terga VI–VIII. Some species associated with the slopes of the Andes Mountains also share with L. amazonensis a similar pattern of the shagreened area of the propleuron (not or slightly extending posteriorly along the lateral margin) and the shape of male abdominal tergum VII (where the posterior margin forms four small, rounded lobes); these are L. distanti Montandon, L. elongatus Rodrigues & Sites, L. malkini La Rivers, L. ochraceus Montandon, and L. pallescens (Stål). Important features to distinguish L. amazonensis from the Andean species are the shapes of the mesosternal carina and female subgenital plate. Distribution. This species is known only from the type locality, in the Serra da Mocidade, state of Roraima, northern Brazil (Fig. 13A). Etymology. The specific epithet refers to the region in which the specimens were collected. Type material examined. All specimens brachypterous.

Percursos urbanos : momentos de relação público-privado
Get PDFMestrado integrado em ArquitecturaExame público realizado em 11 de Julho de 2012A presente dissertação de mestrado surge na continuidade do trabalho realizado na cadeira de Projecto III, como culminar da aprendizagem do percurso de estudo do curso de Arquitectura. No âmbito da cadeira de Projecto III procedeu-se, em primeira instância, à leitura crítica da área de estudo situada em Lisboa, entre a Ribeira das Naus e o novo Terminal de Cruzeiros projectado por Carrilho da Graça. Posteriormente, desenvolveram-se três propostas: um percurso, um complexo de piscinas e dois hotéis. Estes projectos exploram o programa, o sítio e outros elementos que possam contribuir para a implementação de novas relações entre individuo, edifício e espaço, construindo-se assim o lugar de cada um deles.
Neste contexto, o tema da dissertação: "Percursos Urbanos: momentos de relação público/privado", procura explorar a temática das relações espaciais no contexto urbano. Para tal torna-se necessário abordar noções caracterizadoras da realidade espacial que a arquitectura propõe.
Foram escolhidas três Igrejas que procuram clarificar o tema no contexto urbano. Três Igrejas, uma vez que o "seu" espaço apela ao transcendente, caracterizando-se por construir relações particulares entre o ambiente exterior e o seu interior - espaço de reflexão por excelência.
Pretende-se, estudar a complexidade que existe no desenho e na elaboração de um espaço público ou espaço privado. O carácter de um espaço não é determinado pela designação (público/privado, interior-exterior), mas é sim resultado das vivências.

Estudo do pré-condicionamento com n-metil-d-aspartato (NMDA) em convulsões induzidas por ácido quinolínico em camundongos
Get PDFDissertação (mestrado) - Universidade Federal de Santa Catarina. Centro de Ciências Biológicas. Programa de Pós-Graduação em Neurociências.O objetivo deste estudo foi avaliar o tipo de morte celular no hipocampo e córtex cerebral induzida pela administração de AQ em camundongos, bem como avaliar os efeitos do pré-condicionamento com NMDA sobre a expressão da caspase-3, fragmentação de DNA e sobre o sistema antioxidante da glutationa. Os camundongos foram tratados com NMDA (75mg/kg, 10ml/kg i.p) 24 h antes da infusão de AQ (4µl, 9.2mM i.c.v.). O AQ não promoveu fragmentação do DNA tanto no córtex cerebral como no hipocampo, sugerindo morte celular por necrose. O PC com NMDA não promoveu alteração na fragmentação do DNA, demonstrando que não possui efeito neurotóxico. O PC com NMDA e a infusão de AQ não promoveram alterações na expressão da pró-caspase-3 e da caspase-3. O PC com NMDA e a infusão de AQ não alteraram o conteúdo de glutationa total, e a atividade das enzimas glutationa redutase e da glicose 6-fosfato desidrogenase. Contudo, um aumento na atividade da glutationa S-transferase foi observado no córtex após o tratamento com NMDA e AQ. Além disso, o PC com NMDA preveniu a diminuição na atividade da glutationa peroxidase induzida pelo AQ no hipocampo, mas não teve efeito sobre a diminuição da atividade da GPx cortical
