Reconhecimento da tectônica mezozóica-cenozóica na borda leste da Bacia do Paraná através da aplicação de traços de fissão em apatitas no Domo de Pitanga (Sudoeste de Rio Claro, SP)

A tectônica Mesozóica-Cenozóica na borda leste da Bacia do Paraná foi interpretada com base no estudo geocronológico de uma importante feição estrutural conhecida como Domo de Pitanga (sudoeste de Rio Claro, SP), que, como outras estruturas do mesmo tipo presentes na borda da bacia, coincide com grandes alinhamentos estruturais formados pela reativação de estruturas preexistentes no seu embasamento. O método utilizado foi o de datação por análise de traços de fissão em apatitas, o qual permite a modelagem térmica entre 120oC e a temperatura ambiente. Utilizando apatitas de rochas sedimentares, foi possível a modelagem da história térmica da área, graças à homogeneidade dos dados que cada amostra apresentou em função do aquecimento no Eocretáceo pelo magmatismo Serra Geral. Além do resfriamento posterior ao magmatismo marcado pelas idades (Eocretáceo), foram detectadas as principais épocas de resfriamento na área de estudo, sendo elas do Neocretáceo, Paleoceno e, com menor importância, do Mioceno. Estes períodos remontam a importantes eventos tectônicos ocorridos no Sudeste brasileiro, bem descritos no embasamento cristalino. Fica clara a influência desta tectônica de caráter ascensional do embasamento adjacente no interior da bacia, atuando na formação de estruturas, como é o caso do Domo de Pitanga.

Agricultura familiar em Rio Claro - SP: em busca de alternativas para permanência no campo

As we focusing in the Brazilian rural area we see that it presents the spatial diversity and the different organization forms of the space arising from its diversity, tied to the different economic, social, politic and cultural contexts .These contextual diversities bring results that is not limited to the agrarian sector, but get beyond the border of the rural world, taking different ways of organization and structuring in the urban areas. The building and management of the rural spaces are constituted as an attribute of the agricultural production that in the course of the centuries made disappear and reduce significant proportions from the natural areas. In many places, the intensification of the production process gives satisfaction to the globalized markets and that return allows the reproduction of the productive conditions. In other areas the access difficulties to the market and the proximity to the developed urban centers cause the abandonment of the agricultural activity and the maintenance of property without production or with specific services (tourism, for example). That process triggers a multiplicity of factors that are defining the pace of the rural areas in Brazil. This work sought to understand all the deals of the ‘’rural’’ county of Rio Claro-SP and what’s the role and the situation that we find the familiar agriculture in the advanced urban areas, which is the case of this study. Where the agriculture doesn’t represent the flagship of the economy. It was the intention, identify what activities and practices socio-spatial are developed in the county rural area. Trying to understand the public politics acts in the promotion and encouragement to the already developed activities or even other activities that can represent the possibility of a social and territorial reproduction of the families on the country

Análise morfométrica da alta bacia do rio Jacuí

This course conclusion project is linked to the work of the research group at the Chronology and Chronometry Center of UNESP-Rio Claro and also proposes the application of morphometric analysis techniques of the drainage network, by applying Slope Index Value and Extension methods and also the application of longitudinal profile in the far east of the southeast region, more precisely on the border between the states of São Paulo and Rio de Janeiro, in the geomorphological sub-zone of Serra da Bocaina. The research was conducted in the watershed of Jacuí river, in order to outline neotectonical influences and structural controls on the landscape configuration, and also sort the drainage network in relation to the proposed standards in the literature so far today

Three new species of Lebiasina (Characiformes: Lebiasinidae) from the Brazilian Shield border at Serra do Cachimbo, Para, Brazil

Lebiasina marilynae n. sp., L. melanoguttata n. sp., and L. minuta n. sp. are described from the headwaters of the rio Curua in Serra do Cachimbo, Para, Brazil, and represent the only members of the Lebiasininae in the Brazilian Shied, so far. A close relationship among these species is proposed based on: I) the presence of a pair of foramina through which the rain us palatinus of the facial nerve passes, a modification unique in Lebiasinidae and apparently in the Characiformes, 2) the enlargement of the extrascapular bone, 3) the absence of the secondary stripe, and 4) the nearly equal length of caudal-fin lobes. Lebiasina marilynae additionally differs from all congeners in having the primary stripe extending from the tip of the snout to the distal border of the caudal-fin peduncle, the possession of two series of dark blotches parallel to the primary stripe, and a rounded dorsal surface of the mesethmoid. Lebiasina melanoguttata and Lebiasina minuta additionally differ from all congeners in the absence of the primary stripe and the caudal blotch, and the presence of three longitudinal series of dark blotches at the base of the scales of series 3-5. Lebiasina melanoguttata differs from Lebiasina minuta in the absence of a dark blotch at the base of the median rays of the dorsal fin, second infrapharyngobranchial bearing conical teeth, the reddish overall coloration of the eye and fins, and the dark blotches never coalescing (vs. dark dorsal-fin blotch present; the second infrapharyngobranchial being edentulous; dark, olive green eyes, and the yellowish overall color of body and fins; and the dark blotches of longitudinal series 3 and 4 coalescing where scales of adjacent longitudinal series overlap). The occurrence of species of the Lebiasininae on the Brazilian Shield is discussed, and the distribution pattern of the species described herein is compared to that of other endemic species of the Serra do Cachimbo, a highly biodiverse area isolated from the rest of the Amazon basin.

West Nile virus in the Rio Grande Valley: A seroprevalence study of juvenile dogs

This study used canine sentinel surveillance and collected a sample of adult mosquitoes to investigate the potential impact of West Nile virus (WNV) in human populations in the Rio Grande Valley along the Texas-Mexico border. Samples for this study were collected from juvenile dogs two months to one year of age in animal shelters located in the Rio Grande Valley. The sample was comprised of stray dogs in order to include animals with maximum nighttime exposures to Culex mosquitoes. Serum samples were collected following the 2007 WNV transmission season and were tested for IgG antibodies against WNV. Evidence of antibodies to WNV was found in 35.1% of the sample population consisting of 74 dogs. During this same time period, mosquitoes in Brownsville were trapped and morphologically identified to develop greater understanding of the mosquito populations in the region and to further understand other potential mosquito vectors for disease transmission. The vast majority of mosquitoes living in this area were Aedes albopictus (47.6%), Culex quinquefasciatus (23.7%), and Aedes aegypti (20.1%). This study shows that WNV and the vector responsible for WNV transmission are active in the Rio Grande Valley and pose a threat to the human and animal populations. ^

A community-based assessment of the spatiotemporal distribution of influenza in a U.S.-Mexico border county during the spring 2009 novel H1N1 swine-origin influenza A pandemic

This study retrospectively evaluated the spatial and temporal disease patterns associated with influenza-like illness (ILI), positive rapid influenza antigen detection tests (RIDT), and confirmed H1N1 S-OIV cases reported to the Cameron County Department of Health and Human Services between April 26 and May 13, 2009 using the space-time permutation scan statistic software SaTScan in conjunction with geographical information system (GIS) software ArcGIS 9.3. The rate and age-adjusted relative risk of each influenza measure was calculated and a cluster analysis was conducted to determine the geographic regions with statistically higher incidence of disease. A Poisson distribution model was developed to identify the effect that socioeconomic status, population density, and certain population attributes of a census block-group had on that area's frequency of S-OIV confirmed cases over the entire outbreak. Predominant among the spatiotemporal analyses of ILI, RIDT and S-OIV cases in Cameron County is the consistent pattern of a high concentration of cases along the southern border with Mexico. These findings in conjunction with the slight northward space-time shifts of ILI and RIDT cluster centers highlight the southern border as the primary site for public health interventions. Finally, the community-based multiple regression model revealed that three factors—percentage of the population under age 15, average household size, and the number of high school graduates over age 25—were significantly associated with laboratory-confirmed S-OIV in the Lower Rio Grande Valley. Together, these findings underscore the need for community-based surveillance, improve our understanding of the distribution of the burden of influenza within the community, and have implications for vaccination and community outreach initiatives.^

Características de ecossistema e sustentabilidade: estudo sobre a vegetação original e remanescente da bacia hidrográfica do Rio Canoas

Com o objetivo de comparar em termos de paisagem, a vegetação florestal nativa com os fragmentos da vegetação remanescente na bacia hidrográfica do Rio Canoas, situada na divisa dos Estados de São Paulo (à Nordeste) e Minas Gerais (à Centro-Oeste), busca-se dar subsídios aos atores locais para trabalhar políticas públicas com vistas à sustentabilidade do uso dos recursos naturais na região. Foram mapeados sete tipos de vegetação, com destaque para o cerrado e a floresta estacional semidecidual. O método do estudo é exploratório, realizado em fontes secundárias, pesquisa bibliográfica e documental, baseado no estudo de mapas e suas simulações, dados do IBGE, Embrapa, Ministério do Meio Ambiente e trabalhos de autores, como: Cogo (1987), Coutinho (2000) e Bozini (2005). Observou-se que a bacia hidrográfica objeto em estudo é degradada historicamente pelos diversos usos e ocupações do solo e sua maior parte ainda está sujeita à um elevado nível de perturbação, seja pela pecuária, ou mesmo pelas plantações de laranja, milho, eucalipto, cana-de-açúcar e, principalmente, pela cultura do café.

The Security Challenges for the 2016 Rio de Janeiro Olympic Games

Brazilians greeted the long-awaited decision of making Rio de Janeiro the host of the 2016 Olympic Games with tremendous exhilaration. Although Rio’s fantastic natural beauty certainly added to its attraction in hosting the games, its alarming rates of urban crime and violence largely associated with drug trafficking immediately triggered worldwide criticism, and put at issue its ability to guarantee the security for the games. Brazilians have been vying for a position as an emerging global economy and understand the importance of the Games for international prestige. This makes the stakes very high when hosting the Olympic Games in the wake of the 2014 Soccer World Cup, which will also be held in Brazil. This paper explores these criticisms and assesses Rio’s ability to prepare for this important event. The paper further explores the consensus that Brazilians will be more equipped to address actions taken by organized crime capable of affecting the Olympic Games than to face a terrorist attack. Brazil – and Rio – does not figure in the “terrorism map” as a region particularly linked to terrorism. Aside from uncorroborated suspicions of activities by terrorist organizations on the Tri-Border region (Argentina, Brazil, and Paraguay), Brazil does not elicit many concerns regarding terrorism.1 Yet, there is no way to guarantee that terrorist organizations will not try to make use of the 2016 Rio Olympic Games to advance their agenda. This being in mind, Rio and Brazil in general face a long road ahead to prepare, prevent, protect and respond to a possible terrorist attack during the 2016 Olympics. It is clear that prevention and preparation towards potential threats to the Games must necessarily include cooperation and exchange of best practices with other countries. 1 U.S. Department of State has confirmed that this area may have been used to transport weapons and conduct financial affairs in the past. This type of activity has been made more difficult with the fortification of border controls in more recent times.

O homem maldito, de Carlos Eugênio Fontana: o início do romance sul-rio-grandense.

O presente trabalho pretende contribuir para a compreensão do sistema literário sulrio- grandense e, para isso, pretende-se divulgar e analisar a obra literária do autor gaúcho Carlos Eugênio Fontana, a qual se revelou de suma importância para a compreensão da formação do sistema literário no Rio Grande do Sul, sendo que este autor foi o primeiro a publicar romance na cidade de Rio Grande e o quarto no Estado. Em 1858, Carlos Eugênio Fontana publicou o romance O homem maldito e, em 1860, a novela Cenas da vida. Por serem precursoras do gênero no Estado e estarem dentro do padrão literário vigente na época, o estudo destas obras torna-se necessário para a compreensão do processo literário na região sul do país. Contudo, cabe ressaltar que as análises deter-se-ão no romance O homem maldito, por este apresentar recursos literários propícios a uma investigação teórica. Desta forma, buscar-se-á analisar a obra do referido autor com o contexto literário da época em que foi produzida. Além disso, no decorrer da investigação, buscar-se-á analisar as discussões entre história e literatura presentes no romance O homem maldito, foco deste estudo, discutindo questões referentes ao gênero da obra, assim como estudar-se-á também a formação do sistema literário gaúcho, do qual Carlos Eugênio Fontana faz parte, observando a questão da produção/recepção de sua obra.
