    Lucas Veríssimo Warren

    Full Text Available A individualização e o mapeamento da Formação Serra Alta no Estado de São Paulo sempre foi motivo de controvérsia na comunidade geológica. Apesar de apresentar extensão comparável à Formação Irati em subsuperfície, a unidade ainda carece de estudos mais acurados acerca de seu posicionamento estratigráfico, conteúdo fossilífero, sistema deposicional e idade. Na região centro-leste do Estado de São Paulo, a Formação Serra Alta sucede estratigraficamente a Formação Irati, sendo constituída por depósitos pelíticos cinza escuros. A unidade é mapeada desde o limite sul do estado até o Domo de Gibóia, no Município de Rio das Pedras. Neste local, as formações Serra Alta e Teresina são substituídas pelos depósitos pelíticos da Formação Corumbataí, que se estende para norte, além do limite do Estado de São Paulo, e pode ser considerada unidade correlata a estas. Neste estudo, são apresentadas seções colunares e caracterizados os contatos da Formação Serra Alta com as formações permianas verticalmente contíguas. É apresentada também detalhada análise de fácies, com a finalidade de caracterizar o sistema deposicional. A análise de perfis de sondagem possibilitou também melhor compreensão dos padrões arquiteturais da Formação Serra Alta, auxiliando na determinação de sua real distribuição e posição estratigráfica na porção centro-sul do estado. A integração das informações obtidas permitiu identificar tendências de empilhamento transgressivo particulares, contribuindo para o detalhamento da sucessão predominantemente regressiva em que se depositaram as unidades permianas da Bacia do Paraná.

    Full Text Available Estudos florísticos das comunidades de macroalgas lóticas no Brasil são quase que exclusivamente baseadas em material do Estado de São Paulo. Informações sobre macroalgas de riachos são escassos no Estado do Paraná. Neste contexto, o presente trabalho teve como objetivo realizar o levantamento florístico das comunidades de macroalgas de riachos da Serra da Prata, uma área bem preservada e protegida de Floresta Ombrófila Densa. As amostras foram realizadas em 14 segmentos de riachos. O levantamento resultou na identificação de 19 táxons (15 infragenéricos, três genéricos e uma fase do ciclo de vida de Batrachospermum spp., distribuídos em quatro divisões. Cyanophyta foi a divisão com maior número de representantes (58% das espécies e Microcoleus subtorulosus Gomont ex Gomont foi a espécie mais bem distribuída. A maioria dos táxons encontrados (53% são primeiros registros no Estado do Paraná, ao passo que alguns outros são considerados de ocorrência rara em riachos brasileiros. Estes resultados reforçam a importância e a necessidade de mais estudos florísticos e taxonômicos para que se amplie o conhecimento sobre a biodiversidade das comunidades de macroalgas de riacho no Brasil.Studies of stream macroalgal communities in Brazil are almost exclusively based on data from São Paulo state. There are no extensive studies concerning stream macroalgae in Paraná state. In this context, the main objective of this study was to survey the flora of stream macroalgal communities in the Serra da Prata, a well-preserved and protected area of dense Atlantic rain forest. Sampling was carried out in 14 stream segments. The survey resulted in the identification of 19 taxa (15 infrageneric, three generic and one life cycle stage of Batrachospermum spp., distributed in four divisions. Cyanophyta was the division with the highest number of taxa (58% of the species and Microcoleus subtorulosus Gomont ex Gomont was the most widespread

    Full Text Available Analogue experiments were carried out to get insights into the processes governing positive inversion during the foreland propagating thrust tectonics in the southern Serra do Espinhaço, a Brasiliano/Panafrican foldthrust belt in southeast Brazil. In particular, model listric half-grabens were inverted by applying contractional displacement to the footwall blocks. We investigated two different inversion conditions in listric half-grabens: (i extensional and contractional detachments at the same level and (ii at different positions. The models revealed that the development of a forward-breaking thrust system occurs in the basin synrift deposits, by contractional translation of the extensional footwall block when the extensional and contractional master faults do not coincide. Our experiments show the tectonic imbrication between basement and synrift sequences which characterizes the southern Serra do Espinhaço, and support the location in the eastern mountain range domain of the Espinhaço rift master fault system, which is not exposed at the surface.Em experimentos de areia foi simulada a inversão positiva com o intuito de investigar os processos que governam a tectônica da Cordilheira do Espinhaço Meridional na borda sudeste do Cráton São Francisco. Analisou-se, em particular, a evolução progressiva de hemigrabens, com falha de borda lístrica, na qual o fechamento da bacia ocorreu através da translação do bloco do muro da falha mestra. Duas condições foram investigadas: (i os descolamentos distensivos e compressivos ocorrem na mesma cota e (ii os descolamentos situam-se em posições diferentes. Os modelos revelaram que um sistema de falhas de cavalgamento com estilo colapso da lapa se desenvolve no interior do depósito sinrift quando os descolamentos não coincidem. O imbricamento entre escamas do pré- e sinrift, nos modelos, permite esboçar uma analogia com a tectônica da porção sul da Cordilheira do Espinhaço e situar a

    Full Text Available Abstract Background The island of Timor lies at the south-eastern edge of Indonesia on the boundary of the Oriental and Australian faunal regions. The country of Timor-Leste, which occupies the eastern part of the island, is malarious but anopheline faunal surveys and malaria vector incrimination date back to the 1960 s. Over the last decade the malaria vectors of south-east Asia and the south-west Pacific have been intensely studied using molecular techniques that can confirm identification within complexes of isomorphic species. The aim of this study is to accurately identify the Anopheles fauna of Timor-Leste using these techniques. Methods The survey was carried out over the period February to June 2001. Standard entomological techniques - human landing collections, larval collections and CO2 baited light traps - were used to collect anophelines from the main geographical regions: coastal plains, inland plains, and highlands. Specimens were processed for identification by morphology and genotyped for the ribosomal DNA ITS2 by restriction analysis and/or DNA sequencing. Phylogenetic relationship of Anopheles sundaicus and Anopheles subpictus individuals was also assessed using DNA sequences from the ITS2 and mitochondrial cytochrome-b. All specimens, other than those from larval surveys, were processed to detect the presence of the Plasmodium parasite circumsporozoite protein by ELISA for vector incrimination. Results Of 2,030 specimens collected, seven species were identified by morphology: Anopheles barbirostris, Anopheles aconitus, Anopheles annularis, Anopheles maculatus, Anopheles peditaeniatus, An. sundaicus and Anopheles vagus. These were confirmed by molecular analysis with the addition of Anopheles flavirostris and an unidentified species designated here as An. vagus genotype B. This latter species was morphologically similar to An. vagus and An. subpictus and is likely to be the An. subpictus described by other workers for Timor

    Full Text Available In this paper 19 additional mammalian species are reported in the Atlantic forest of the Paranean Serra do Mar, southern Brazil, including threatened and rare species. These findings resulted from a one-year field research in the western slope of the Serra do Mar, Piraquara municipality, with additional review of reports about mammal distribution in the region. Preliminarily mammal richness in the region is round 54 species, but this number could be higher with more systematic surveys, particularly with regards to bats. The occurrence of the hog-nosed skunk, Conepatus chinga (Molina, 1782, is reported for the first time in the eastern portion of Paraná, a State vastly deforested during the last century in Brazil.Neste artigo, 19 espécies adicionais de mamíferos são informadas para a Floresta Atlântica da Serra do Mar paranaense, sul do Brasil, incluindo espécies ameaçadas e raras. Este relato é resultado de uma pesquisa de campo de um ano na vertente oeste da Serra do Mar, município de Piraquara¸ com revisão adicional de relatos sobre a distribuição de mamíferos na região. A riqueza preliminar de mamíferos na Serra do Mar paranaense é de 54 espécies, mas este número poderá aumentar quando mais inventários faunísticos forem realizados, principalmente para morcegos. A ocorrência do cangambá, Conepatus chinga (Molina, 1782, é relatada pela primeira vez na porção leste do Paraná, um Estado altamente desflorestado neste último século no Brasil.

    2012-10-01

    Full Text Available O presente trabalho investigou a evolução do relevo da média Serra do Espinhaço Meridional (SdEM, região que delimita três das mais importantes bacias hidrográficas do sudeste brasileiro: à oeste, a do rio São Francisco e, à leste, as dos rios Doce e Jequitinhonha. Os procedimentos metodológicos basearam-se na utilização de dois tipos de análises. A primeira baseou-se em observações de campo e em análises cartográficas e visou reconhecer áreas onde os processos erosivos eram mais ativos. A segunda objetivou mensurar a atual denudação geoquímica em 16 bacias hidrográficas que se localizam nas duas vertentes da média SdEM. Os resultados demonstram que a litologia predominante – quartzito – é extremamente resistente aos processos intempéricos e desnudacionais e que o arcabouço litoestrutural controla os processos desnudacionais da área investigada. Demonstram ainda que, embora a vertente leste apresente relevo mais dissecado, fato que indica que no passado nesta vertente os processos desnudacionais eram mais intensos, é na vertente oeste que, atualmente, os processos desnudacionais geoquímicos são mais agressivos.

    2011-01-01

    Abstract Fieldwork conducted throughout Timor-Leste in September 2004 and July 2009 resulted in a collection or recording of 263 herpetological specimens (100 amphibians, 163 reptiles), comprising at least seven species of frogs and toads, 20 species of lizards, seven species of snakes, two species of turtles, and one species of crocodile. Among the amphibians, the most frequently encountered species were toads (Duttaphrynus melanostictus), rice paddy frogs (genus Fejervarya), and rhacophorid treefrogs (Polypedates cf. leucomystax). All three variants of rice paddy frogs encountered represent undescribed species similar to Fejervarya verruculosa from neighboring Wetar Island. Records of Fejervarya cancrivora and Fejervarya limnocharis for Timor Island are apparently errors based on misidentification. We obtained voucher specimens for a total of 147 lizards and voucher photographs only for four specimens of Varanus timorensis. Aside from geckos frequently associated with human habitations (e.g., Gehyra mutilata, Gekko gecko, Hemidactylus frenatus, Hemidactylus platyurus), we discovered an as yet undescribed species of bent-toed gecko, genus Cyrtodactylus, in the Same valley. Our specimens of Hemidactylus platyurus are the first record of this species from Timor-Leste. Commonly encountered skinks included four-fingered skinks (genus Carlia), wedge skinks (genus Sphenomorphus), and night skinks (genus Eremiascincus). Notable among the 15 snakes collected was the frequency of pitvipers (Cryptelytrops insularis), which amounted to over 25% of all snakes. Our specimen of the wolfsnake Lycodon subcinctus is the first record of this species for Timor-Leste. Based on these findings, it appears that the biodiversity of amphibians and reptiles in this remote corner of Wallacea is much greater than previously thought, particularly with respect to scincid lizards. The detail we provide in the species accounts is designed to allow the use of this report as a preliminary field

    Full Text Available The aim of this study was to inventory the mayfly fauna, based on nymphal and alate stages, in Serra da Mantiqueira and in Serra do Mar, São Paulo State, as well as to present information about habitats used by the genera. Nymphs were collected in several streams and mesohabitats with a Surber sampler and the winged stages with light attraction methods, entomological nets, and Malaise traps. In all, eight families and 33 genera were recorded, representing a very significant portion of the Brazilian fauna (80% of families and 49% of genera. Furthermore, it was possible to identify 11 species, of which two are new records for the state: Tricorythodes santarita Traver and Caenis reissi Malzacher. Despite the high diversity recorded, the accumulation curves presented an ascending form, indicating an increase in the number of genera with additional sampling effort. The high richness found in these areas are in agreement with the high biodiversity of the Atlantic Forest biome and the sampling effort employed, which included the use of different methods, the collection of both nymphs and winged stages, and the sampling of a large area with diverse streams and habitats.

    Full Text Available Taludes rochosos em rodovias são superfícies potencialmente instáveis, que frequentemente condicionam quedas de blocos, afetando a segurança dos usuários de rodovias, a infraestrutura dos transportes e o meio ambiente. O comportamento geológico-geotécnico dos maciços rochosos e as condições geométricas e de trafegabilidade das rodovias são aspectos fundamentais na avaliação do perigo de queda de blocos. Esta pesquisa busca aplicar um método de avaliação do perigo de queda de blocos rochosos em taludes de rodovias, objetivando a classificação e hierarquização dos segmentos rodoviários com base em critérios definidos. Neste contexto, doze taludes rochosos do sistema rodoviário do Espírito Santo foram investigados, a partir de parâmetros, visando à obtenção de um índice para expressar o grau de perigo aos condutores que trafegam pelos trechos, denominado índice de queda de blocos. A efetividade dos parâmetros no método adotado também foi avaliada. Os taludes foram hierarquizados, definindo-se ainda medidas prioritárias para intervenções em cada trecho, de forma a minimizar os problemas causados em cada segmento.

    2012-05-01

    Full Text Available This article shows how space and time indexed social identity in the market place of one of the larger ‘towns’ of Timor-Leste (or ‘East Timor’, Viqueque during the years 1966-1967 and examine their relevance for today’s Viqueque town. The space occupied by the weekly emporium offered a forum in which ethnicity, social hierarchy, gender, a pastime (cockfighting, and religious affiliation visually played themselves out and presented a physical replication of social distinctions that defined the character of the town and the sub-district it served.Focusing on gender, ethnicity, social class, and social identity, and their economic implications, also enables us to gain insight into the process whereby post-colonial nations transform themselves after gaining independence. By comparing the use made of social space at two periods of time separated by four decades during which momentous developments took place in Timor-Leste we can see in sharper relief the kind of changes urban spaces experience when they are subject to colonial authority, pressures resulting from independence, and – ultimately – the tortuous process of nation-building.

    Full Text Available Aspectos referentes à morfogênese mesozóico-cenozóica da Serra dos Órgãos no Estado do Rio de Janeiro, região sudeste do Brasil, foram investigados por meio da análise morfotectônica. Os resultados permitiram reconhecer padrões anômalos na rede de drenagem e nas formas de relevo, que encontram correspondência com dois eventos tectônicos superpostos, de caráter regional, no sudeste do país. O primeiro evento tectônico teria operado no Eoceno, caracterizado por distensão de direção NWSE, considerado como gerador do Rift Continental do Sudeste do Brasil.Sua principal conseqüência seria a compartimentação do relevo em blocos alongados e escalonados abatidos para sudeste. Concomitantemente a este abatimento, deu-se a deformação de uma antiga superfície de aplainamento, que teria nivelado a cimeira da Serra dos Órgãos em torno de 2.000 m s.n.m. O regime tectônico seguinte, caracterizado por cisalhamento destral, com binário E-W, de idade pleistocênica a holocênica, envolveria uma retomada dos processos erosivos, com desenvolvimento de drenagens ao longo de lineamentos de direção NW-SE, hoje realçadas pelas facetas trapezoidais parcialmente preservadas ao longo do vale do rio do Bonfim.

    Full Text Available The geochemical characterization of thirteen Serra Geral Group flows in the Vista Alegre region (RS-SC, southern Brazil, displays the homogeneous basaltic composition near 50 wt.% SiO2. Each of the five basal flows (Pitanga-type, high-Ti/Y ~600, TiO2 > 3 wt.% and eight upper flows (Paranapanema-type, medium Ti/Y ~400, TiO2 > 2 wt.% can be identified from their chemical composition; sets of flows have parallel variation in chemical composition. The flow-by-flowcorrelation in four sections shows the horizontal position of the flows in three profiles and an approximately 200-m downdrop of the Itapiranga block with respect to the Frederico Westphalen block. The world-class amethyst geode mineralization and the systematic presence of native copper in the basalts make the correlation of great geological and economic significance.A caracterização geoquímica de treze derrames do Grupo Serra Geral na região de Vista Alegre (RS e SC, sul do Brasil, exibe uma composição basáltica homogênea próxima a 50% de SiO2. Os cinco derrames basais são classificados quimicamente como tipo Pitanga (alto Ti/Y ~600 e TiO2 > 3 em peso percentual, os demais oito derrames possuem médio Ti/Y ~400 com TiO2 ~2.5 em peso percentual, sendo classificados como magma tipo Paranapanema. Cada derrame pode ser identificado através de sua composição química e correlacionado, com variação paralela entre os perfis estudados. A correlação derrame a derrame nos quatro perfis demonstra uma posição horizontal em três perfis e um rejeito vertical de aproximadamente 200 m do bloco Itapiranga em relação ao bloco Frederico Westphalen. A presença de jazidas de ametista em geodos e a sistemática ocorrência de cobre nativo nos basaltos da região tornam a correlação de grande significado geológico e econômico.

  11. Education in Timor-Leste: Envisioning the Future

    Directory of Open Access Journals (Sweden)

    Robin Burns

    2017-04-01

    Full Text Available Timor-Leste is a small state that finally achieved independence in 2002. It has had to re-build an entire education system from a small base largely destroyed in the independence struggle. This paper presents the issues identified in pre-independence meetings, and considers these within the framework of transition and transformation problems for a small island with a diverse population and a long history of colonisation, using Namibia as an apt example. Fifteen years later, teacher preparation both pre- and in-service is identified as a major issue in achieving educational and social goals, with language training a key factor. Enrolments have improved and gender equity is close to parity, but urban-rural differences remain. Late enrolments, drop-outs especially in the early years, and repetition are major hurdles in achieving an educated, knowledgeable and qualified population.

    Few studies have explored the relationships between nation-building, disaster risk reduction and climate change adaptation. Focusing on small island developing states, this paper examines nation-building in Timor-Leste, a small island developing state that recently achieved independence. Nation-building in Timor-Leste is explored in the context of disaster risk reduction, which necessarily includes climate change adaptation. The study presents a synopsis of Timor-Leste's history and its nation-building efforts as well as an overview of the state of knowledge of disaster risk reduction including climate change adaptation. It also offers an analysis of significant gaps and challenges in terms of vertical and horizontal governance, large donor presence, data availability and the integration of disaster risk reduction and climate change adaptation for nation-building in Timor-Leste. Relevant and applicable lessons are provided from other small island developing states to assist Timor-Leste in identifying its own trajectory out of underdevelopment while it builds on existing strengths.

  1. The complex impact structure Serra da Cangalha, Tocantins State, Brazil

    Science.gov (United States)

    Kenkmann, Thomas; Vasconcelos, Marcos A. R.; Crósta, Alvaro P.; Reimold, Wolf U.

    2011-06-01

    Serra da Cangalha is a complex impact structure with a crater diameter of 13,700 m and a central uplift diameter of 5800 m. New findings of shatter cones, planar fractures, feather features, and possible planar deformation features are presented. Several ring-like features that are visible on remote sensing imagery are caused by selective erosion of tilted strata. The target at Serra da Cangalha is composed of Devonian to Permian sedimentary rocks, mainly sandstones that are interlayered with siltstone and claystones. NNE-SSW and WNW-ESE-striking joint sets were present prior to the impact and also overprinted the structure after its formation. As preferred zones of weakness, these joint sets partly controlled the shape of the outer perimeter of the structure and, in particular, affected the deformation within the central uplift. Joints in radial orientation to the impact center did not undergo a change in orientation during tilting of strata when the central uplift was formed. These planes were used as major displacement zones. The asymmetry of the central uplift, with preferred overturning of strata in the northern to western sector, may suggest a moderately oblique impact from a southerly direction. Buckle folding of tilted strata, as well as strata overturning, indicates that the central uplift became gravitationally unstable at the end of crater formation.

Nymphs were collected in several streams and mesohabitats with a Surber sampler and the winged stages with light attraction methods, entomological nets, and Malaise traps. In all, eight families and 33 genera were recorded, representing a very significant portion of the Brazilian fauna (80% of families and 49% of genera. Furthermore, it was possible to identify 11 species, of which two are new records for the state: Tricorythodes santarita Traver and Caenis reissi Malzacher. Despite the high diversity recorded, the accumulation curves presented an ascending form, indicating an increase in the number of genera with additional sampling effort. The high richness found in these areas are in agreement with the high biodiversity of the Atlantic Forest biome and the sampling effort employed, which included the use of different methods, the collection of both nymphs and winged stages, and the sampling of a large area with diverse streams and habitats.O objetivo do trabalho foi inventariar a fauna de Ephemeroptera, com base em ninfas e estágios alados, da Serra da Mantiqueira e Serra do Mar no estado de São Paulo, bem como gerar informações sobre os hábitats utilizados pelos gêneros registrados.

Our fieldwork culminated in the discovery of one putative new frog species (genus Kaloula), at least five putative new lizard species (genera Cyrtodactylus,Cryptoblepharus, and Sphenomorphus), and two putative new snake species (genera Stegonotus and Indotyphlops). In addition, we present new distribution records of amphibians and reptiles for 11 of the country's 12 contiguous districts, along with additional natural history data. Results from our surveys increase the number of amphibian and reptiles known to occur in Timor-Leste from 22 species before our surveys began to over 60, including over 20 as yet undescribed species.

  12. Participatory Theater, Is It Really? A Critical Examination of Practices in Timor-Leste

    2013-01-01

    Full Text Available Dance, music, and oral narratives are an important and vibrant part of cultural practice and heritage in Timor-Leste. But while Timorese people have used such creative methods and processes during rituals, celebrations, and their fight for independence, today arts and artistic expression become an increasingly popular strategy in development cooperation. Especially diff erent forms of so-called participatory theater with origins in development cooperation, arts, and social movements, present themselves as innovative, participatory, and well applicable in terms of capacity building and stimulating positive social transformation. Based on the author’s experience and observations, this article critically examines the alliance between various stakeholders in Timor-Leste engaging with the fact that the current scene of participatory theater can hardly be seen as an independent grassroots or even social movement, rather than an initiated top-down process by donors with specific agendas.

    Full Text Available In December 2005, eleven Cuban educational advisers arrived in Timor-Leste to begin work on a national literacy campaign. Adapting the program known in Latin America as Yo, Sí Puedo (Yes I Can, the Cubans trained over 400 local tutors to run classes in every part of the country, using a method they call ‘alphanumeric’, delivered via audiovisual technology. The campaign was launched in March 2007, and the first classes began in June of that year. By September 2010, three years later, over 70,000 adults, over one fifth of the total illiterate population, had successfully completed a thirteen week basic literacy course. Drawing on original research undertaken in Timor-Leste between 2004 and 2009, followed by further investigations in May 2010 in Havana, Cuba, this paper describes the Timor-Leste campaign, locating it within the historical commitment of the country’s independence movement to adult literacy, and the broader context of Cuba’s international literacy work.

    Full Text Available In Timor-Leste, customary institutions contribute to sustainable and equitable rural development and the establishment of improved access to and management of land, water and other natural resources. Drawing on multi-sited empirical research, we argue that the recognition and valorization of custom and common property management is a prerequisite for sustainable and equitable land tenure reform in Timor-Leste. In a four-community study of the relationship between land access and the practice of rural livelihoods in eastern and western districts of Timor-Leste, where customary management systems are dominant, we found different types of traditional dispute resolution, with deep roots in traditional forms of land management and with varying levels of conflict. The article shows how customary land tenure systems have already managed to create viable moral economies. Interviewees expressed a desire for the government to formalize its recognition and support for customary systems and to provide them with basic livelihood support and services. This was more important than instituting private landholding or state appropriation of community lands, which is perceived to be the focus of national draft land laws and an internationally supported project. We suggest ways in which diverse customary institutions can co-exist and work with state institutions to build collective political legitimacy in the rural hinterlands, within the context of upgrading the quality of rural life, promoting social and ecological harmony, and conflict management.

    Full Text Available The study of plant succession provides information on vegetation dynamics of a region and, therefore, improves our understanding of the natural trends of present ecosystems. With this objective, plant succession based on palynology of a sediment profile in a swamp forest was studied on the Lower Northeast Slope of Serra Geral, Rio Grande do Sul. Samples were treated with HCl, HF, KOH and acetolysis; slides were mounted in glycerol-jelly. For each sample a minimum of 500 grains of pollen + pteridophyte and bryophyte spores was counted and other palynomorphs were counted in parallel. Tilia and Tilia Graph software were used to construct percentage and concentration diagrams, with three 14C datings. The results show a local water reservoir in the beginning of the Holocene (± 9800 yrs. BP, creating a herbaceous plant marsh by hydrosere. The initial colonization of the marsh by trees occurred about 8800 yrs. BP, with tropical species from the Coastal Plain migrating in an east-west direction. Afterwards, there was a dry phase between 7000-5000 yrs. BP. The second appearance of regional tree species began at about 5000 yrs. BP, resulting in the present forest and in the west-east migration of tropical species from interior lowlands, like this one, to re-colonize the coast after the last marine regression.O estudo de sucessão vegetal permite obter informações sobre a dinâmica da vegetação de uma região e, portanto, compreender melhor os ecossistemas da atualidade e suas tendências naturais.

    Full Text Available Groundwater with anomalous fluoride content and water mixture patterns were studied in the fractured Serra Geral Aquifer System, a basaltic to rhyolitic geological unit, using a principal component analysis interpretation of groundwater chemical data from 309 deep wells distributed in the Rio Grande do Sul State, Southern Brazil. A four-component model that explains 81% of the total variance in the Principal Component Analysis is suggested. Six hydrochemical groups were identified. δ18O and δ2H were analyzed in 28 Serra Geral Aquifer System samples in order to identify stable isotopes patterns and make comparisons with data from the Guarani Aquifer System and meteoric waters. The results demonstrated a complex water mixture between the Serra Geral Aquifer System and the Guarani Aquifer System, with meteoric recharge and ascending water infiltration through an intensive tectonic fracturing.

    Full Text Available Este trabalho tem por objetivo sistematizar e aplicar conceitos da Semântica Argumentativa de Oswald Ducrot e Marion Carel, no que diz respeito ao modelo teórico dos Blocos Semânticos, de modo que dêem conta da construção do sentido de unidades mais complexas como o texto e o discurso. A tese concebida como norteadora deste estudo, seguindo a metodologia proposta por Ducrot (1987, pressupõe que o texto é um bloco semântico inscrito no nível teórico da produção e realizado pelo encadeamento argumentativo complexo que é o discurso, orientado argumentativamente pelo uso de conectores tipo DC e/ ou PT. As análises discursivas realizadas, neste trabalho, demonstram que os encadeamentos dos enunciados estão bem marcados pelos conectores donc e pourtant que dão sentido ao discurso complexo, pelas conexões semânticas produzidas em suas AI e AE. Esse movimento argumentativo resulta da interdependência dos segmentos argumentativos, dos encadeamentos e por conseqüência dos blocos semânticos, todos interconectados e interdependentes nas relações de sentido que estabelecem entre si, processo que culmina na realização linguística de nível complexo constituído pelo texto, entidade abstrata subjacente aos discursos realizados, e pelo discurso, como seqüência de enunciados interligados, por isso, também entendido como entidade concreta, ou seja, a manifestação e realização do texto.

    Full Text Available O estudo foi realizado no Parque Nacional da Serra dos Órgãos (PARNASO, estado do Rio de Janeiro, no contexto da Serra do Mar e com vegetação típica da Mata Atlântica. O objetivo foi relacionar a organização do solo na paisagem, integrando os fatores pedológicos, geomorfológicos e geológicos. Os solos mostram seqüências assimétricas entre a vertente continental, mais suave, em relação à oceânica, com ruptura brusca de relevo. Os solos mostram polaridade evolutiva crescente entre o topo e base das vertentes. A vertente continental apresenta a seguinte toposseqüência com continuidade pedológica evolutiva: afloramentos rochosos, Neossolos Litólicos, Cambissolos, Argissolos e Latossolos. Por outro lado, a vertente oceânica mostra uma toposseqüência truncada, também com polaridade evolutiva do topo para a base: Afloramentos Rochosos, Cambissolos, Argissolos e Latossolos. A assimetria das vertentes é marcada pela escarpa oceânica formada por uma importante zona de falha na direção NE-SW. Nos compartimentos de Planalto os Neossolos Litólicos são associados localmente a Gleissolos, afloramentos  rochosos e Plintossolos Pétricos, desenvolvidos sobre granitos equigranulares e isotrópicos. No compartimento de Planalto Dissecado os Cambissolos são associados localmente a Plintossolos e Neossolos Litólicos e ocorrem sobre relevos multiconvexos relacionados com saprolitos de rochas gnáissicas ou de estrutura de fluxo ígneo. Os Argissolos são associados localmente a Latossolos e Chernossolos em depósitos formados em porções deprimidas de vales encaixados e formados por facetas trapezoidais. Estes ambientes refletem o contínuo processo de erosão por escorregamentos, movimentos de massa e quedas de blocos das porções mais elevadas e a intemperização destes materiais nas porções mais baixas.

    The Serra do Mar (SM) mountain range located along the southeast Brazilian continental margin is characterized by a low-lying coastal plateau separated from the elevated inland plateau by a steep escarpment. This morphology is a result of reactivation of Precambrian shear zones since the break-up of the Western Gondwana and opening of the South Atlantic Ocean in Early Cretaceous (1). Previous Thermochronological data from southeast Brazilian highlands (2,3), indicates that the landscape evolution is associated with several distinct exhumation events. In order to clarify the intensity and duration of the post-break up tectonic processes that shaped the SM we have undertaken a low temperature thermochronology study of crystalline basement, from the plateaus and escarpments situated between south of Rio de Janeiro and São Paulo state. Apatite fission track (AFT) and (U-Th/He) and (AHe) dating has been combined with geologic information to generate precise thermal histories and make initial attempts to quantify the amount of exhumation. AFT ages range from 145 to 53 Ma whereas preliminary AHe ages range from 75 to 37 Ma. Forward modeling using QTQt confirms Late Cretaceous-Paleogene cooling identified earlier (4,5) and identifies a distinct cooling phase in Neogene, between 30 and 10 Ma. Neogene cooling rapid caused exhumation of rocks 1 km through of the crust mainly in south portion of the SM in Rio de Janeiro state. (1) Almeida, 1976. An.

    Full Text Available Um dos fundamentos da realização desta pesquisa refere-se à possibilidade de minimizar os impactos ambientais decorrentes da exploração da rocha calcária. Nesta vertente, esta pesquisa apresenta um estudo de caráter experimental voltado à incorporação de resíduo calcário em formulações de blocos sílico-calcários para alvenaria estrutural, avaliando a viabilidade técnica de produção destes através da determinação de suas propriedades físico-mecânicas, representadas nesta pesquisa pela retração linear de cura, absorção de água, porosidade aparente, massa específica aparente e módulo de ruptura à flexão em três pontos. Ao término do estudo acerca da incorporação do resíduo nos blocos, foi constatado que torna-se inviável a sua utilização como agente aglomerante na mistura, tendo em vista que não propicia a formação de silicato hidratado de cálcio na mistura, o que resulta em valores pouco significativos no que concerne aos resultados das propriedades físico-mecânicas.

    Full Text Available A adoção das formações aluviais na reconstituição de eventos geomorfológicos é uma ferramenta metodológica importante para a compreensão dos processos de esculturação dos vales fluviais, da configuração espaço-temporal da rede hidrográfica e, consequentemente, da configuração do modelado do relevo no Quaternário tardio. Este trabalho investiga hipóteses sobre os fatores condicionantes que levaram à configuração de expressivos fundos de vale colmatados na bacia do Alto-Médio Rio Pomba, região leste de Minas Gerais. Os fundos de vale apresentam espessos níveis de terraços nos quais as planícies, por vezes com amplitudes anômalas, encontram-se embutidas ou encaixadas. O quadro geológico e geomorfológico regional, as idades obtidas via método de Luminescência Opticamente Estimulada (LOE para os sedimentos e a disposição de trechos de corredeira no médio Rio Pomba sugerem que a gênese dos depósitos fluviais esteve condicionada por uma tectônica diferencial de blocos durante o Quaternário tardio. A morfologia das planícies se deve à combinação de fatores antrópicos e tectônicos, além de ser influenciada pela morfologia da bacia do Rio Pomba.

Neste artigo, analisa‑se a forma como em Timor‑Leste a cultura tem sido interpretada, processada e incorporada em programas de desenvolvimento das Nações Unidas (ONU. Que tipo de concessões fazem as agências de desenvolvimento? Quais são os limites neste processo de hibridização e será que este implica uma renegociação das abordagens de desenvolvimento ou apenas concessões unilaterais? O artigo argumenta que os esforços das agências da ONU para aumentar a sua sensibilidade cultural nas operações em Timor‑Leste tinham claras limitações e não conseguiram refletir a cultura local em toda a sua diversidade. Nesta complexa interação entre variantes de cultura local, assimetrias de poder e ortodoxia internacional, as agências de desenvolvimento estão simultaneamente um passo atrás, na sua compreensão da cultural local, e um passo à frente, em termos do seu poder para definir as regras de envolvimento.

    2015-01-01

    In Timor-Leste, high fertility, high maternal mortality and low levels of contraceptive prevalence demonstrate the importance of exploring perceptions, policies and practices around reproductive health and rights. This paper explores the influence of the Catholic Church on reproductive decision-making at different levels of policy and practice. Utilising a feminist qualitative research methodology, in-depth interviews were conducted with a range of participants including nuns and priests, Timorese women and men of different ages and backgrounds and local and national stakeholders working in reproductive health and women's rights. Findings reveal that the Church is reported to play a significant role in reproductive health and rights decision-making at all levels of society, from policy-making to the reproductive decisions made by individual Timorese women and men. Nevertheless, the translation of Church teachings into practice, particularly by nuns, priests and Timorese men and women, reveal a range of attitudes and opinions; some that support and others that contest official Catholic doctrine. In light of the significant influence of the Timorese Catholic Church on policy and practice at many levels of society, there is a need to prioritise the development of rights-based strategies to improve reproductive health services in Timor-Leste.

    Full Text Available The livestock species play very important economic and socio-cultural roles for the wellbeing of rural households, such as food supply, source of income, asset saving, source of employment, soil fertility, livelihoods, transport, agricultural traction, agricultural diversification and sustainable agricultural production. The aim of this work was to identify and characterize the different roles that livestock and livestock species play in rural communities of Timor-Leste, highlighting the importance of animal production for the wellbeing and rural development, and relate the functions performed by livestock production with economic, social and cultural attributes of the communities. The data used in this study were collected in 2011 through a questionnaire survey in three rural communities in the district of Bobonaro, namely in a mountain area, an irrigation plain and a coastal zone, and were complemented with secondary data. Livestock production in Timor-Leste is predominantly familiar being chickens, pigs, goats, cattle, horses, buffaloes and sheep the main species. Beyond the economic function, each livestock species also performs social and cultural functions.

    Full Text Available A caracterização anatômica de regiões encefálicas topograficamente bem definidas é particularmente útil para a prática neurocirúrgica por propiciar melhor compreensão da tridimensionalidade das suas estruturas e das lesões que as acometem, e por incitar uma maior sistematização dos seus acessos cirúrgicos. Neste sentido, se destaca no interior de cada hemisfério cerebral, um verdadeiro bloco único composto externamente pela ínsula, internamente pelos núcleos da base e tálamo, e que abriga no seu interior a cápsula interna. Com uma conformação predominantemente biconvexa e disposto entre a cisterna silviana e as cavidades ventriculares supratentoriais, esse bloco cerebral central morfologicamente se caracteriza como uma cabeça de cada metade do tronco encefálico, encoberta por todo o manto neocortical do seu hemisfério ao qual se une através de verdadeiros istmos constituídos pelos prolongamentos das diferentes partes da cápsula interna. Anteriormente e sob o sulco limitante anterior da ínsula se dispõem as fibras que compõem o ramo anterior da cápsula interna, superiormente e sob o seu sulco limitante superior se dispõem as fibras restantes do ramo anterior e as do joelho e do ramo posterior, entre as quais se destacam em importância funcional as fibras piramidais córtico-espinhais, e sob o sulco limitante inferior da ínsula se dispõem as partes retro e sub-lentiformes da cápsula interna, que englobam as radiações auditiva e visual. Lateralmente o bloco cerebral central tem a ínsula como um verdadeiro escudo externo das principais estruturas cerebrais subcorticais. As escolhas dos acessos microneurocirúrgicos às lesões relacionadas com o bloco cerebral central devem ter como maior preocupação as suas relações topográficas com o tálamo e com as fibras da cápsula interna.The caracterization of well defined and circumscribed brain regions is particularly useful for the neurosurgical practice once

    Smoking is a global public health concern. Timor-Leste is facing a rapidly growing epidemic of tobacco use. The trend of smoking in Timor-Leste seems to be increasing and the magnitude of the problem affects people who smoke before reaching adulthood. One of the factors implicated in the continuously rising trend of smoking among young people in Timor-Leste is clearly due to unavailability of restrictive laws and regulations. Therefore, our study sought to analyze available dataset from the Global Youth Tobacco Survey (GYTS) for developing a comprehensive national smoking policy in order to lower smoking risks among young people in Timor-Leste. We conducted a secondary analysis of the 2009 GYTS in Timor-Leste. The 2009 GYTS assessed 1657 in-school students aged 13-15 years for current smoking prevalence and determinants of tobacco use. We used IBM SPSS version 21 software to analyze the data. Frequency analyses were computed to identify demographic characteristics of study participants. Bivariate logistic regression analysis was performed to examine the association between each demographic characteristic as well as each independent variable and the outcome of being current smokers. Out of 1657 in-school students, 51 % were of ages less than 15; 53 % were girls; and 45 % were in grade 2. Prevalence of current cigarette smoking was found to be 51 %. The prevalence of current smoking among in-school students increased with ages (from 46 % in less than 15 to 57 % in 15 plus). Boys were more likely to be smokers than girls (59 % versus 28 %). Significant factors positively associated with current smoking included parental smoking; closed-peer smoking; number of days people smoked in the house; having family discussion about harmful effects of smoking; being smoking in areas such as school, public places and home; and having seen cigarette advertisements on billboard. Timor-Leste has higher prevalence of cigarette smoking among minors, especially among boys. Our analysis

The aim of this study was to determine the risk factors for pulmonary tuberculosis in the Dili District. Methods: The study design was a case-control. Cases were patients with positive BTA pulmonary tuberculosis, and controls were non TB patients registered at two TB clinics (Motael and Bairro-Pite and the three public health centers (Comoro, Formosa and Becora in Dili, July 2013 - February 2014. Numbers of samples were 138 people consisting of 46 cases and 92 controls (1:2. Risk factors studied were smoking habits, contact with patients, nutritional status, family income, population density, sun lighting, ventilation and the use of firewood for cooking. Data were collected through interviews, observation and measurement. Bivariate analysis was performed to determine the similarity between cases and controls and to calculate the crude OR. Multivariate analysis with logistic regression was performed to determine adjusted risk factors that contribute to the increasing TB patients. Results: There were no significant differences between cases and control groups in age, gender, education and occupation (p>0.05. Bivariate analysis showed that the risk factors of pulmonary tuberculosis were the contact with patients (OR=2.809; 95%CI:1.337-5.900, nutritional status (OR=2.380; 95%CI:1.096-5.169, the sun lighting (OR=8.090; 95%CI:3.468-18.872 and ventilation (OR=6.141; 95%CI:2.709-13.924.

    The climate in Timor Leste (East Timor) is predicted to become about 1.5 °C warmer and about 10 % wetter on average by 2050. By the same year, the population is expected to triple from 1 to 2.5-3 million. This article maps the predicted changes in temperature and rainfall and reviews the implications of climate change and population growth on agricultural systems. Improved cultivars of maize, rice, cassava, sweet potato and peanuts with high yield performance have been introduced, but these will need to be augmented in the future with better adapted cultivars and new crops, such as food and fodder legumes and new management practices. The requirements for fertilizers to boost yields and terracing and/or contour hedgerows to prevent soil erosion of steeply sloping terrain are discussed. Contour hedges can also be used for fodder for improved animal production to provide protein to reduce malnutrition.

    Considering the goal of Ergonomic Work Analysis to establish, from the point of view of workers, safe, healthy, comfortable and efficient environments, this study propose to analyze the work situation of machine operators at five joineries from Florianópolis-SC. For this, it was applied the LEST Method to evaluate the task made by the operators, considering the physical, cognitive and organizational work environment. As results, it was identified the main ergonomics problems of these workstations, presenting an ergonomic diagnosis and their implications on health and safety of workers. As result, it was concluded that the main ergonomics problems at joineries are related with noise, with constant load of weight and with the postures taken. Besides these problems, others were diagnosed, for example, the pressure for workers to comply strictly the task stipulated and also the poor training and capacity of workers.

    Full Text Available This paper outlines the context in which many thousands of people went missing in Timor-Leste between 1975 and 1999. The issues related to estimating the exact number of missing are discussed, followed by a review of the mechanisms implemented by the government and civil society since independence to attempt to examine and investigate the fate of missing persons. The paper then examines the technical details involved with searching for the missing which impact on the effectiveness of the different mechanisms. Further complexities related to scientific and religious/cultural beliefs when dealing with the missing are discussed. The paper concludes with providing suggestions for ways that the future search for the missing can realistically continue in light of other competing development priorities.

A análise cinemática dos milonitos datados mostra estruturas extensionais bem preservadas com movimento de topo para ESE, compatível com o de estruturas encontradas em outros segmentos tectônicos na porção leste do Quadrilátero Ferrífero e na região do Vale do Rio Doce. Nossas idades situam-se nomesmo intervalo de tempo definido para o magmatismo alcalino da Suíte Serra do Mar. Sugerimos que o arcabouço tectônico regional tenha sido desenvolvido durante um processo de extensão em escala continental. Este processo teria sido contemporâneo da deformação em condições de convergência ligada a zonas de cisalhamento Neoproterozóicas dos cinturões Apiaí/Ribeira e Araçuaí, as quais compõem segmentos importantes destes cinturões. Os dados disponíveis mostram que estas estruturas não podem ser relacionadas simplesmente ao colapso gravitacional pós-orogênico, mas devem envolver um processo mais complexo relacionado provavelmente ao balanço dinâmico entre espessamento e afinamento crustal durante os eventos de convergência tectônica, formação de bacias e exumação.

Partindo-se de um traço de referência, fez-se a caracterização dos materiais componentes da mistura (cimento, areia média e pedrisco para a confecção de corpos-de-prova cilíndricos de 10x20cm. Em seguida, procedeu-se a moldagem de corpos de prova com a substituição do agregado miúdo por adições do resíduo de pneu nas porcentagens de 10%, 20% e 30%, em massa. Investigou-se nas amostras os parâmetros de Massa Específica e Resistência à Compressão. Analisou-se, de forma comparativa, os resultados obtidos nos corpos-de-prova de referência com os confeccionados com pneu. Verificou-se que até o limite de 30% de resíduo de pneu, a mistura apresentou trabalhabilidade e coesão, atingindo uma resistência à compressão de 12MPa. Tal valor pode ser considerado elevado em se tratando de blocos que serão usados apenas em calçadas, onde o tráfego será exclusivo de pedestres.

    There are 176 species representing eight genera and two families of Plecoptera known from Brazil. However, only ten of these species are recorded from the State of Bahia. In this study, an inventory of stoneflies from the southern region of Bahia State, Serra Bonita, including the municipality of Camacan, was undertaken from 2007-2012. Stoneflies were collected using UV light pan traps, Malaise traps, and aerial nets. One new gripopterygid species, Tupiperla bispoi n. sp., is described and illustrated. Four genera representing ten other species are recorded: Gripopteryx cancellata, G. clemira, G. garbei, G. pinima, Paragripopteryx sp., and Tupiperla tessellata (Gripopterygidae), Kempnyia alterosarum, K. gracilenta, K. jatim, and K. neotropica (Perlidae). With the present study, the number of known species of stoneflies recorded from Bahia State is 17, ten of these recorded from the Serra Bonita region.

    Thin sections and single grains of pyroxenes from the Serra de Mage feldspar cumulate eucrites were studied by X-ray crystallography, electron microprobe and optical techniques. It was concluded that the pyroxene crystallized as pigeonite. On cooling augite was exsolved along (001) and inverted to hypersthene, with exsolution of (100) augite from hypersthene during continued slow cooling. The estimated original bulk composition of the pigeonite pyroxene is Wo10En51Fs39. The compositional data, textural relations, and existence of P2 sub 1 ca hypersthene suggest very low cooling (about 0.0004 deg C/year) below 800 deg. The Serra de Mage augite lamellae were found to be as thick or thicker than those of Moore County and Moama meteorites.

    Fire is currently perceived as a major threat to ecosystems and biodiversity in the mountains of the Mediterranean region. Portugal's highest mountain range, the Serra da Estrela, is one of the country's most important protected areas and also the most fire-prone. We present a ˜14,000-year fire history based on microscopic charred particles in an infilled glacial lake to better understand the antiquity of biomass burning and its effects on Mediterranean vegetation at the Atlantic margin. Results indicate the continuous occurrence of fire in the Serra da Estrela over the period of the record. Two periods of increased fire activity - around 12,000-11,000 calendar years before the present (cal. a BP) and 3500-2500 cal. a BP - were accompanied by major vegetation changes and followed by long periods of vegetation stabilisation. Cross-correlation analyses reveal that post-fire succession consistently began with herbaceous vegetation, followed by forest and shrubland stages. Past successional trends were often markedly different to those observed at present. Holocene climatic changes, including shifts in the North Atlantic Oscillation, played a pivotal role in the vegetation development and fire history of the Serra da Estrela. In the late Holocene, human use of fire became a major agent of vegetation change, accelerating the Holocene decline of forests.

    Full Text Available Brazil faces a challenge to develop biomonitoring tools to be used in water quality assessment programs, but few multimetric indices were developed so far. This study is part of an effort to test and implement programs using benthic macroinvertebrates as bioindicators in Rio de Janeiro State. Our aim was first to test the Multimetric Index for Serra dos Órgãos (SOMI for a different area - Serra da Bocaina (SB - in the same ecoregion. We sampled 27 streams of different sizes and altitudes in the SB region. Despite the environmental similarities, results indicated biological differences between reference sites of the two regions. Considering these differences, we decided to develop an index specific for the SB region, the Serra da Bocaina Multimetric Index (MISB. We tested twenty-two metrics for sensitivity to impairment and redundancy, and six metrics were considered valid to integrate the MISB: Family Richness, Trichoptera Richness, % Coleoptera, % Diptera, IBE-IOC index, EPT / Chironomidae ratio. A test of the MISB in eleven sites indicated it was more related to land-use and water physico-chemical parameters than with altitude or stream width, being a useful tool for the monitoring and assessment of streams in the bioregion.

    Classical swine fever virus (CSFV) is a highly infectious pathogen of pigs and believed to be a major constraint to pig production in Timor-Leste. The Ministry of Agriculture and Fisheries conducts vaccination campaigns in an attempt to control clinical disease, however, there is no empirical data available concerning the seroprevalence and distribution of CSFV in Timor-Leste. To help address this knowledge deficit, a cross-sectional study to determine seroprevalence was conducted in the three districts that border Indonesia. Data on farmer- and pig-level factors were also collected to look at their impact on CSFV serological status. Overall, true CSFV seroprevalence was estimated at 34.4%. Seroprevalence estimates varied widely between and within districts, subdistricts, and villages. Older pigs and pigs that had been vaccinated for CSFV were more likely to test positive for CSFV antibody. Pigs owned by farmers that experienced the sudden death of pigs in the 12 months prior to the survey were more likely to test positive for CSFV antibody, while pigs that had been sick in the previous three months were less likely to test positive for CSFV antibody. The final multivariable model accounted for a large amount of variation in the data, however, much of this variation was explained by the random effects with less than one percent of the variation explained by the fixed effects. This work further supports the need for a collaborative approach to whole-island CSFV control between West Timor, Indonesia and Timor-Leste. Further work is needed to better understand the risk factors for CSFV serological status in order to allocate resources for control. As CSFV is now endemic in Timor-Leste research involving a combination of serology, antigen detection and in-depth investigation of suspect cases over a period of time may be required.

    Marcela Paschoal Perpétuo

    Full Text Available ABSTRACT: The Serra da Aldeia Suite is composed by circular or oval-shaped plutons, intrusive in meta-sedimentary and meta-volcanosedimentary rocks in the Riacho do Pontal Fold Belt, NE Brazil. The Serra das Melancias Pluton, belonging to Serra da Aldeia Suite, is located southeastern of Piaui state, near Paulistana city. These plutons represent a major magmatic expression in this area and contain important information about the late magmatic/collisional geologic evolution of the Brasiliano Orogeny. Based on petrographic and geochemical data, three facies were defined in the Serra das Melancias Pluton: granites, syenites and quartz monzonites. The rocks display high-K and alkaline to shoshonitic affinities, are metaluminous and show ferrous character. They are enriched in Light Rare Earth Elements and Large Ion Lithophile Elements, with negative anomalies in Nb, Ta and Ti. Their high Ba, Sr, K/Rb, low Rb, relatively low U, Th, Nb to very low Heavy Rare Earth Elements and Y resemble those of typical high Ba-Sr granitoids. The geochemical data suggest the emplacement of Serra das Melancias Pluton in a transitional, late to post-orogenic setting in the Riacho do Pontal Fold Belt during the late Brasiliano-Pan African Orogeny.

    The evidence-based policy (EBP) movement has received significant attention in the scientific literature; however, there is still very little empirical research to provide insight into how policy decisions are made and how evidence is used. The lack of research on this topic in low- and middle-income countries is of particular note. We examine the maternity waiting home policy in Timor-Leste to understand the role of context, policy characteristics, individual actors, and how evidence is used to influence the policy agenda. The research tracked the maternity waiting home policy from 2005 to 2009 and is based on in-depth interviews with 31 senior policy-makers, department managers, non-government organization representatives, and United Nations advisors. It is also informed by direct observation, attendance at meetings and workshops, and analysis of policy documents. The findings from this ethnographic case study demonstrate that although the post-conflict context opened up space for new policy ideas senior Ministry of Health officials rather than donors had the most power in setting the policy agenda. Maternity waiting homes were appealing because they were a visible, non-controversial, and logical solution to the problem of accessing maternal health services. Evidence was used in a variety of ways, from supporting pre-determined agendas to informing new policy directions. In the pursuit of EBP, we conclude that the power of research to inform policy lies in its timeliness and relevance, and is facilitated by the connection between researchers and policy-makers.

    Residues of the herbicides simazine, metribuzin, metolachlor, trifluralin, atrazine, and two metabolites of atrazine, deisopropylatrazine (DIA) and deethylatrazine (DEA), are surveyed in the surface and groundwater of the Primavera do Leste region, Mato Grosso, Brazil during September and December 1998 and April 1999. Different water source sampling stations of groundwater (irrigation water well, drinking water well, and water hole) and surface water (dam and river) are set up based on agricultural land use. A solid-phase extraction procedure followed by gas chromatography-nitrogen-phosphorus detection is used for the determination of these compounds. All compounds are detected at least once in water samples. A temporal trend of pesticide contamination is observed, with the highest contamination frequency occurring in December during the main application season. Metribuzin shows the highest individual detection frequencies throughout the monitoring period, followed by metolachlor, simazine, and DEA. The maximum mean concentrations of pesticides in this study are in the range from 0.14 to 1.7 microg/L. We deduct that the contamination of water resources is predominantly caused by non-point pollution of pesticides used in intensive cash-crop cultures of the Cerrado area. Therefore, a continuous monitoring of pesticide concentrations in water resources of this tropical region is necessary to detect the longer term contamination trends and developing health risks.

    Full Text Available A uva Merlot é uma cultivar originária da região de Bordeaux, França, uma das responsáveis pela notoriedade dos vinhos de Saint-Émilion e Pomerol. Na Serra Gaúcha, é a segunda vinífera tinta com maior área plantada. Na safra de 2007, a produção dessa uva alcançou 11.399t, representando 31% das uvas tintas viníferas processadas. O objetivo do trabalho foi avaliar a composição físico-química de vinhos Merlot elaborados na Serra Gaúcha, visando a sua identidade varietal, à caracterização regional e à formação de um banco de dados. Foram analisados 34 vinhos, safras 2000 a 2003, de 30 vinícolas. As análises foram realizadas na Embrapa Uva e Vinho, em Bento Gonçalves, RS. As determinações clássicas foram efetuadas por meio de métodos físico-químicos; os elementos minerais, por espectrofotometria de absorção atômica; e os compostos voláteis, por cromatografia gasosa. Os resultados mostram que os vinhos Merlot se enquadraram nos limites estabelecidos pela legislação brasileira. Foram observados valores elevados de matiz e baixos dos índices de cor avaliados a 520nm e 620nm, variáveis que participam do aspecto visual dos vinhos. Foram constatados teores elevados de acetato de etila e 1-propanol, compostos voláteis que influenciam as características sensoriais, e de K, que interfere na acidez e na conservação do vinho.

    Full Text Available Foi realizado um experimento para avaliar o efeito da suplementação de feno de Tifton (Cynodon dactylon, com blocos multinutricionais formulados com diferentes níveis de melaço, sobre a digestibilidade, o consumo e a uréia sangüínea. Foram utilizados quatro bezerros Hereford de aproximadamente um ano de idade, com peso médio no início do experimento de 196 kg. O delineamento experimental utilizado foi o quadrado latino, porém a fim de incluir o tratamento sem suplementação, os dados foram analisados em blocos casualizados. Os tratamentos foram: sem suplementação e suplementação com blocos elaborados com quatro níveis de melaço: 25; 30; 35 e 40%. A suplementação aumentou a digestibilidade da matéria seca e matéria orgânica significativamente. Não foram encontradas diferenças significativas no consumo de MS entre tratamentos. A suplementação diminuiu o consumo de matéria seca de feno, gerando um coeficiente de substituição de 0,58, porém aumentou o consumo total de matéria seca, matéria orgânica e proteína bruta. Embora não tenha sido encontrada diferença significativa entre os tratamentos suplementados com blocos, o consumo de matéria orgânica digestível aumentou significativamente com a suplementação, bem como a uréia sangüínea. A fim de avaliar alguns parâmetros ruminais como pH e N-NH3, foi realizado outro experimento com três bezerros Hereford fistulados no rúmen. Os tratamentos utilizados foram: feno de Tifton sem suplementação e suplementação com blocos com 25 e 30% de melaço. O delineamento experimental utilizado foi quadrado latino 3 x 3. A suplementação não alterou o pH ruminal a níveis críticos para digestão da fibra, porém aumentou significativamente a concentração de N-NH3 ruminal.

    The health services system of Timor-Leste (T-L) will, by 2015, add 800 physicians, most of them trained in Cuba, to the 233 employed by the national health system in 2010-2011. The need for more physicians is not in discussion: poor health indicators, low coverage and utilization of services, and poor quality of services are well documented in T-L. However, the choice of this scaling-up, with a relatively narrow focus on the medical workforce, needs to be assessed for its relevance to the health profile of the country, for its comprehensiveness in terms of other complementary measures needed to make it effective. This article discusses the potential effects of the rapid scaling-up of the medical workforce, and the organizational capacity needed to monitor the process and eventually mitigate any deleterious consequences. The analysis is based on a review of documentation collected on site (T-L) and on interviews with key-informants conducted in 2011. We stress that any workforce scaling-up is not simply a matter of increasing numbers of professionals, but should combine improved training, distribution, working conditions, management and motivation, as a means towards better performing health services' systems. This is a major challenge in a context of limited organizational and managerial capacity, underdeveloped information systems, limited training and research capacity, and dependency on foreign aid and technical assistance. Potential risks are associated with funding the additional costs of recruiting more personnel, associated expenditures on infrastructure, equipment and consumables, the impact on current staff mix, and the expected increased demand for services. We conclude that failing to manage effectively the forthcoming "great leap forward" will have long term effects: formal policies and plans for the balanced development of the health workforce, as well as strengthened institutions are urgently needed.

In order to clarify the problem, the authors of the present study selected two lines of research: 1detailed geomorphologic mapping; and 2laboratory analysis of the glacial deposits. This sedimentological study, which had not been carried out before in the area, proved to be very significant for the diagnosis of the style and extent of the glaciation. We can confirm the Serra do Gerês glaciaion. The vestiges are particularly clear and important on the Eastern side of the mountain and in the Fafião valley, where the most important glacigenic sediment complex is found. At the glaciation maximum, an ice dome reached the thickness of some 150m in both the Couce and the Compadre areas, from whence outlet glaciers radiated into the main peripheral valleys. At that time the upstream sector of the Homem Valley glacier must have reached the thickness of about 300m. Recent absolute dating, using cosmogenic isotopes in glaciated granitic surfaces, suggested that the glaciation maximum in the Gerês is older than the Last Glaciation.

    Full Text Available Este artigo apresenta uma análise do discurso do turismo considerando suas diversas manifestações. Essa análise possibilita entender que o discurso é fator de constituição da realidade do turismo. Por outro lado, o discurso do turismo seria um modelo que reflete a ação social dos atores da economia centrada no mercado, desconsiderando as necessidades das comunidades receptoras. O discurso descreve e explica o turismo, justificando sua importância e considerando-o uma fonte de lazer, prazer e uma alternativa de desenvolvimento econômico por meio da inclusão social. Ao se enfatizar os aspectos positivos e as cifras do seu desempenho, por meio do discurso, se evidencia a relevância econômica do turismo. Para fundamentar essas questões, este artigo analisa matérias do jornal Zero Hora sobre situações pontuais de contextos geográficos da Serra Gaúcha, como a Região das Hortênsias, a Região da Uva e do Vinho e os Campos de Cima da Serra.

    Full Text Available The Atlantic Forest is a priority area for the conservation of amphibians, with some regions already showing knowledge gaps. We analyzed the composition and richness of anuran species in an area of dense ombrophilous forest at Serra do Tabuleiro, the seasonal richness variation, and the daily activity of males during vocalization shifts. We collected samples of anurans from two permanent ponds and from a track within the forest for 14 months. We recorded 32 anuran species, among which Aplastodiscus cochranae, A. ehrhardti, and Hypsiboas poaju are included in the list of endangered species in the state. The highest number of species was associated to spring and summer. The most frequent anuran species were H. bischoffi, Adenomera araucaria, and Physalaemus nanus, registered throughout the study period. The daily activity of males was concentrated between 8 p.m. and 12 p.m., but some species keep vocalizing overnight, indicating that vocal activity can differ among species undergoing the same weather conditions. The diversity of anurans recorded in our study was high, including endangered species and species with poor biological knowledge, reinforcing the relevance of Serra do Tabuleiro as a priority area for preserving the Atlantic Forest.

  12. Demographic and spatial predictors of anemia in women of reproductive age in Timor-Leste: implications for health program prioritization.

    Andrew A Lover

    Full Text Available Anemia is a significant risk factor for poor health outcomes for both the mother and neonate; however, the determinants of anemia in many epidemiological settings are poorly understood. Using a subset of a nationally representative cluster survey (2010 Demographic and Health Survey in combination with other non-contemporaneous survey data, the epidemiology of anemia among women of reproductive age in Timor-Leste has been explored. Logistic regression was used to identify risk factors, population-level impacts were estimated as population attributable fractions and spatial analytics were used to identify regions of highest risk. The DHS survey found that ∼ 21% of adult women in Timor-Leste are anemic (49,053; 95% CI: 37,095 to 61,035, with hemoglobin <12.0 g/dL. In this population, the main risk factors (adjusted odds ratio; 95% CI are: currently abstaining from sex for any reason (2.25; 1.50 to 3.38; illiteracy (2.04; 1.49 to 2.80; giving birth within the previous year (1.80; 1.29 to 2.51; consumption of fruits/vegetables low in vitamin A (1.57; 1.13 to 2.20; and the district-level confirmed malaria incidence (1.31; 1.15 to 1.49. A review of prior soil-transmitted helminth surveys in Timor-Leste indicates low-to-moderate prevalence with generally low egg counts, suggesting a limited impact on anemia in this setting, although comprehensive survey data are lacking. Examination of the population-level effects highlights the impacts of both recent births and malaria on anemia, with more limited impacts from diet; the evidence does not suggest a large contribution from geohelminths within Timor-Leste. These patterns are divergent from some other settings in the Asia-Pacific region and highlight the need for further focused research. Targeting high-burden districts and by increasing access to pre/postnatal care, raising literacy levels, increasing access to family planning, and improving malaria control should be prioritized to maximize inherently

    Full Text Available Serra da Capivara National Park and surrounding areas in Southeastern Piau State (Brazil were subjected to morphostratigraphical, sedimentological, and geochronological studies about superficial deposits in order to interpret quaternary paleoenvironmental events. The following sedimentary deposits associated with morphostructural units were identified: colluvial fans at Serra Branca Valley and Structural Staircases, and eluvial-colluvial deposits at Reverse of the Cuesta. There are also colluvial and alluvial deposits outside Serra da Capivara National Park. Many colluvial and alluvial deposits are contemporaneous and indicate a semiarid climate. According to luminescence dating (thermoluminescence and optically stimulated luminescence, the present landscape evolution began around 436 51.5 ka when the Piau River deposited clayey sediments. From 296.55 46.95 ka to 116.3 19.52 ka, the fluvial channel likely exhibited a braided pattern and deposited sand and gravel bars. Penecontemporaneous sands and muds with ages ranging from 202.75 32.81 ka, 135 16.4 ka to 117 14.5 ka were deposited on Serra da Capivara National Park hillslopes. A colluviation episode occurred between 84.7 13.4 ka to 76.2 9.35 ka, which lacks correlatable alluvial deposits. In the Northern hemisphere last glacial maximum, the colluviation and alluviation processes intensified. These depositional processes likely occurred between 15.8 1.9 and 10.35 1.76 ka, during the Holocene-Pleistocene transition.

    The effectiveness of eye movement desensitization and reprocessing (EMDR) therapy for treating trauma symptoms was examined in a postwar/conflict, developing nation, Timor Leste. Participants were 21 Timorese adults with symptoms of posttraumatic stress disorder (PTSD), assessed as those who scored ≥2 on the Harvard Trauma Questionnaire (HTQ). Participants were treated with EMDR therapy. Depression and anxiety symptoms were assessed using the Hopkins Symptom Checklist. Symptom changes post-EMDR treatment were compared to a stabilization control intervention period in which participants served as their own waitlist control. Sessions were 60-90 mins. The average number of sessions was 4.15 (SD = 2.06). Despite difficulties providing treatment cross-culturally (i.e., language barriers), EMDR therapy was followed by significant and large reductions in trauma symptoms (Cohen's d = 2.48), depression (d = 2.09), and anxiety (d = 1.77). At posttreatment, 20 (95.2%) participants scored below the HTQ PTSD cutoff of 2. Reliable reductions in trauma symptoms were reported by 18 participants (85.7%) posttreatment and 16 (76.2%) at 3-month follow-up. Symptoms did not improve during the control period. Findings support the use of EMDR therapy for treatment of adults with PTSD in a cross-cultural, postwar/conflict setting, and suggest that structured trauma treatments can be applied in Timor Leste.

  20. Micromorphology of selected relict slope deposits from Serra da Estrela, Portugal

    2013-04-01

    Serra da Estrela is the highest mountain in Portugal (1,993 m ASL) and part of the Iberian Central Cordillera. The mountain has a strong relief and a lithological diversity with several types of granitoids and metasediments. Most of the western plateau area was glaciated during the Last Glacial Maximum and its morphology is dominated by glacial landforms. Vieira (2004) produced a detailed geomorphological map of Serra da Estrela and described several sites showing stratified slope, head and debris-flow deposits. Based on the geomorphological analysis of the relationships between glacial and periglacial evidence, a first relative chronology was presented. However, a detailed and systematical sedimentological analysis has not been conducted before and absolute ages are also lacking. Micromorphology analysis has proven to be of considerable value in the interpretation of mountain soils and sediments. Such interpretation depends on identifying diagnostic features, indicating factors as the presence or absence of permafrost, thickness of the active layer, ice segregation and the operation of processes of mass-wasting. In this study, micromorphology was used to answer questions concerning the composition, structure, origin and depositional processes of relict slope deposits. Micromorphology allowed a systematic description of the physical characteristics of the sediments. Lamination and sorting, when preserved, are good evidence for overland flow. Features due to deformation (folds, boudins, coatings and tails due to the rotation of clasts) are associated with sliding. Other mass-movements such as debris flows, earth flows, and to a certain extent, dry grain flows may be characterized by similar microscopic facies, typically a poorly sorted, porphyric material. Porosity gives evidence for both liquefaction (debris flows) and frost-induced mass-movement (solifluction). The relict slope deposits of the Serra da Estrela show an increase in cryogenic micromorphological

    We received for examination a small colection of ticks captured in the National Park of the Serra da Canastra (MG), between 1979 and 1980. The authors demonstrated the existence of a broad co-accomodation of Amblyomma pseudoconcolor on Edentata of the family Dasypodidae, being Dasypodini the tribe more adjusted to this infestation. In conformity to the Figs 1 and 2, Dasypodini are probably the real hosts of A. pseudoconcolor and also the oldest hosts. For the first time, A. pseudoconcolor is also recorded on Cabassous tatouay, C. unicinctus, Priodontes maximus and Euphractus sexcincuts. Also for the first time A. pseudoconcolor and Amblyomma calcaratum were recorded in the State of Minas Gerais. The ectoparasites are deposited in the "Departamento de Parasitologia da Universidade Federal de Minas Gerais, Brasil".

    Full Text Available Nella storiografia filosofica spagnola non esiste, probabilmente, una definizione ambigua e problematica come quella che riguarda la cosiddetta "Scuola di Barcellona". La tesi principale di questo articolo è che tale scuola non giunse mai a nascere, ma ne esistette soltanto una forma embrionale che non poté maturare perché, in conseguenza della situazione politica venutasi a creare con la guerra civile (1936-1939, i suoi componenti si dispersero nell'esilio. Ciò nonostante, è possibile riconoscere alcuni tratti comuni, seppur labili e (forse non sostanziali, nella diaspora degli intellettuali catalani che rendono possibile definirla, con le dovute cautele, "Scuola di Barcellona". Tali caratteristiche comuni si possono far risalire a colui che, in un certo senso, fu il fondatore della scuola, essendo il principale maestro delle nuove leve filosofiche della Catalogna all'inizio del XX secolo: Jaume Serra Hunter.

    Full Text Available The article aims to understand the relevance of wine production at Serra Gaúcha region (Rio Grande State, Brazil and unveil the role played by grapes and wine for XIXth century Italian migrants as for their contemporary descendents. A research was conducted at Vale dos Vinhedos (Vineyards Valley,(RS, Brazil, where a strong relation between wine and tourism exists. Bibliographical research, oral history and semi- structured interviews permitted the construction of a collective subject discourse. As a result it was revealed that wine production was important at first for subsistence and also a way to promote economic growth; at present, grapes and wine are cultural identity markers with which community members present themselves to tourist and visitors. It is a case study without intention of generalizing for other wine regions in Brazil and brings a new approach to tourism and heritage relations.

    Antitumor, antimicrobial and antioxidant activities of basil were studied, along with its characterization in phenolic compounds, organic acids and soluble sugars. The results placed basil as a valuable candidate for functionalization and conservation of food products, maintaining their nutritional properties, while increasing their shelf life and potential health effects. The basil leaves were then incorporated in "Serra da Estrela Cheese", either in its dehydrated form or as a decoction. The cheeses were then subject to a nutritional evaluation, being characterized for their fatty acids, minerals and CIE color parameters. To assess the combined effects of plant incorporation and storage time, a 2-way ANOVA was used to process the results, further analysed through a linear discriminant analysis. Overall, basil leaves provided antioxidant activity to the cheeses, reduced the moisture, and preserved the unsaturated fatty acids and proteins. Comparing both incorporation types, the decoctions had a higher functionalizing and conservative effect.

    Full Text Available The pig activity, as well as other livestock activities, is directly dependent on natural resources and therefore the lack of knowledge about the impact on water resources in the cattle industry could compromise the sector's growth. In this context, the water footprint comes as a comprehensive indicator of water use that evaluates which is the fuel used, directly or indirectly, to produce a particular product throughout the supply chain. In this context, this study aimed to evaluate the gray water footprint for pigs slaughtered in 2014 in Corede Serra/RS, in the confinement process. The gray water footprint in Corede Serra was 0.1346 km3. The municipalities of Parai (0.0142 km3, Nova Prata (0.0133 km3 and Serafina Correa (0.0103 km3 showed the largest footprints while the municipalities of São Marcos (0.00001 km3 and Bento Gonçalves (0.00002 km3 presented the smallest footprints. Because of the concentration of phosphorus in pig manure have presented a significant value (1.65 kg animal year-1 when evaluated under the total number of animals slaughtered in each municipality and considering the phosphorus concentration provided for in Conama Resolution n° 357/05, the demand is observed a large volume of water to phosphorus load assimilation. The gray water footprint can be reduced through the use of more efficient technologies for processing of manure, so that phosphorus is removed or reduced to low concentrations.

    Body sway while maintaining an upright quiet stance reflects an active process of balance based on the integration of visual, vestibular, somatosensory, and proprioceptive inputs. Richard Serra's Promenade sculpture featured in the 2008 Monumenta exhibition at the Grand Palais in Paris, France is herein hypothesized to have stimulated the body's vertical and longitudinal axes as it showcased five monumental rectangular solids pitched at a 1.69(°) angle. Using computerized dynamic posturography we measured the body sway of 23 visitors when fixating a cross, or when observing the artwork (fixating it or actively exploring it with eye movements) before and after walking around and alongside the sculpture (i.e., before and after a promenade). A first fixation at the sculpture increased medio-lateral stability (in terms of spectral power of body sway). Eye movement exploration in the depth of the sculpture increased antero-posterior stability [in terms of spectral power and canceling time (CT) of body sway] at the expense of medio-lateral stability (in terms of CT). Moreover, a medio-lateral instability associated with eye movement exploration before the promenade (in terms of body sway sensu stricto) was canceled after the promenade. Finally, the overall medio-lateral stability (in terms of spectral power) increased after the promenade. Fourteen additional visitors were asked to stand in a dark room and adjust a luminous line to what they considered to be the earth-vertical axis. The promenade executed within the sculpted environment afforded by Serra's monumental statuary works resulted in significantly improved performances on the subjective visual vertical test. We attribute these effects to the sculpted environment provided by the exhibition which may have acted as a kind of physiologic "training ground" thereby improving the visitors' overall sense of visual perspective, equilibrium, and gravity.

    Full Text Available Abstract Background The Timor-Leste Ministry of Health has recently finalized the National Malaria Control Strategy for 2010-2020. A key component of this roadmap is to provide universal national coverage with long-lasting insecticide-treated nets (LLINs in support of achieving the primary goal of reducing both morbidity and mortality from malaria by 30% in the first three years, followed by a further reduction of 20% by end of the programme cycle in 2020 1. The strategic plan calls for this target to be supported by a comprehensive information, education and communication (IEC programme; however, there is limited prior research into household and personal usage patterns to assist in the creation of targeted, effective, and socio-culturally specific behaviour change materials. Methods Nine separate focus group discussions (FGDs were carried out in Dili, Manatuto, and Covalima districts, Democratic Republic of Timor-Leste, in July 2010. These focus groups primarily explored themes of perceived malaria risk, causes of malaria, net usage patterns within families, barriers to correct and consistent usage, and the daily experience of users (both male and female in households with at least one net. Comprehensive qualitative analysis utilized open source analysis software. Results The primary determinants of net usage were a widespread perception that nets could or should only be used by pregnant women and young children, and the availability of sufficient sleeping space under a limited number of nets within households. Both nuisance biting and disease prevention were commonly cited as primary motivations for usage, while seasonality was not a significant factor. Long-term net durability and ease of hanging were seen as key attributes in net design preference. Very frequent washing cycles were common, potentially degrading net effectiveness. Finally, extensive re-purposing of nets (fishing, protecting crops was both reported and observed, and may

    Full Text Available Undernourishment continues to be a serious health problem in several regions worldwide and poverty its main and determinative underlying cause. In children, it establishes a favorable field for the development of infectious diseases among them malaria, acquired immunodeficiency syndrome and tuberculosis which simultaneously favour the maintenance of undernourishment and health lethality. In this report, the case of a 5 year- old undernourished girl, who was assisted by the cuban medical staff in Temor Leste, is presented. The patient is diagnosed as a case of pulmonary tuberculosis after a previously prolonged disease associated to malaria, acute respiratory diseases and intestinal parasites which motivated a stepped clinical assistance and further hospital admissions. The patient is still under medical treatment.La desnutrición continua siendo un problema de salud en varias regiones del mundo y la pobreza su causa subyacente principal y determinante. En los niños crea un terreno favorable para el establecimiento y desarrollo de enfermedades infecciosas, entre las que se pueden mencionar: la malaria, el síndrome de inmunodeficiencia adquirida y la tuberculosis, que a su vez contribuyen a mantener la desnutrición y constituyen una significativa causa de mortalidad. Se presenta el caso de una paciente de cinco años de edad, malnutrida, que es atendida por el personal cubano de la salud en Timor Leste y que se diagnostica finalmente con tuberculosis pulmonar luego de una historia prolongada de enfermedad previa marcada por la malaria, las enfermedades respiratorias agudas y el parasitismo intestinal que motivaron su atención escalonada en una clínica, además de posteriores ingresos hospitalarios. La paciente está recibiendo tratamiento médico.

    Full Text Available Neste estudo, avaliaram-se a composição e diversidade no Cerrado em três áreas do Leste de Mato Grosso do Sul, uma das regiões mais ameaçadas e menos estudadas do Cerrado brasileiro. Para tanto, levantaram-se as espécies vasculares em trilhas percorridas em diferentes fisionomias desse bioma, com enfoque especial para as espécies arbustivas e arbóreas. Adicionalmente, nas áreas de Cerrado sensu stricto foram instaladas 30 parcelas de 10 x 3 m, nas quais foram amostrados apenas indivíduos lenhosos > 1 m de altura. No geral, foram levantadas 220 espécies, 150 gêneros e 65 famílias de diferentes formas de vida, incluindo espécies consideradas raras nos Cerrados brasileiros e possíveis novas ocorrências nos Cerrados de Mato Grosso do Sul. A riqueza de espécies arbustivas e arbóreas no Cerrado sensu stricto foi alta (79-101 espécies por área. Houve baixa similaridade florística entre as áreas estudadas, de modo que apenas 50 espécies foram comuns a todas elas. O estudo da vegetação lenhosa por meio de parcelas (total de 651 indivíduos e 105 espécies revelou uma diferença na riqueza média, diversidade (índice de Shannon e dominância (Berger-Parker entre as áreas estudadas. Adicionalmente, a densidade relativa das espécies e a composição florística foram bastante variáveis entre as áreas estudadas (similaridade entre 0,42 e 0,53. Tais resultados colocam as áreas estudadas entre as mais ricas áreas de Cerrado sensu stricto do Brasil, mostrando que áreas marginais de Cerrado podem ser tão ricas quanto suas áreas centrais, mesmo que através da contribuição de elementos florísticos de outras formações florestais. Os resultados reforçam ainda a existência de elevada heterogeneidade florística no Cerrado, mesmo em distâncias relativamente curtas (≤60 km, que pode ser desencadeada por diferenças entre fragmentos em relação à característica de solo, histórico de perturbação e proximidade de outras

    Serra da Cangalha is a complex impact structure with an apparent diameter of 13.7 km located in essentially undisturbed sedimentary rocks of the Parnaíba basin in northeastern Brazil. The stratigraphy of the crater region includes, from bottom to top, the Longá, Poti, Piauí and Pedra de Fogo formations of Devonian to Late Permian age. The age of the impact event is constrained to shatter cones from the central depression. Furthermore, significant cementation with iron oxide is observed in the rocks of Serra da Cangalha, especially in the Poti Formation and in the polymict breccias, conferring to them a peculiar red color. Macroscopic deformation involves faulted, folded and subvertical strata within a ˜2.9 km radius from the center. (ii) The annular basin domain has limited outcrops; its most prominent features are two concentric annular ridges formed by chert breccias and fossilized wood-bearing folded strata of the Pedra de Fogo Formation. (iii) The crater rim and (iv) external domains comprise undisturbed strata of the Pedra de Fogo and Piauí formations with well-preserved sedimentary structures. Whilst the existing literature on Serra da Cangalha has focused on the structure morphology, general geology and some shock features, we present here a detailed description of the stratigraphy and the geology of each formation in the interior and around Serra da Cangalha, as well as further detailed microscopic shock feature analysis. This provides significant evidence that the rocks of the central uplift have undergone shock pressures of, at maximum, 10 GPa.

    This work deals with the genesis and paleoenvironmental significance of relict slope deposits in Serra da Estrela, Central Portugal and is part of a wider sedimentological and dating approach. The aim is to identify what microstructures indicate frost weathering, witch mechanisms are responsible for their development and the effectiveness of frost weathering across an altitudinal profile. Our goals are to contribute to the better understanding of the morphogenetical significance of the different types of slope deposits, clarifying the role of cold environment processes and develop a chronological framework for the Late Quaternary evolution of the slope environment of the mountains of Western Iberia. Quartz grains, 0.5 mm in diameter, were collected from samples from stratified, head and debris-flow deposits. Cailleux (1942) analysis, with modifications from Gozdzik (1980), was performed allowing assessing frosting and rounding, as well as the effects of later frost weathering in vertical profiles from slope deposits. Grains were also analysed using a scanning electron microscope (SEM) following Mahaney (2002). The effects of frost weathering comprise several microstructures such as breakage blocks, conchoidal fractures and fresh surfaces. Breakage blocks microstructures are the most common. Two types of frost weathering were distinguished: weathering of the P type is mainly initiated on convex fragments of grains as the result of ice segregation, and F type is linked to the volumetric expansion of ice and usually observed within concave linear microstructures. The frost action index (FAI) was estimated from the rate of microstructures from frost weathering. FAI varies between 0 and 3. The values of the sediments from the slope deposits vary between 1.2 and 2.05. This approach was for the first time applied on slope deposits from Serra da Estrela. There is a clear correlation between deposits in weathering type. Samples that display intensive physical weathering in

Neste ambiente, foi criado em 1973 o Parque Estadual do Ibitipoca (PEI pelo Instituto Estadual de Florestas de Minas Gerais, que protege uma área de 1488 ha, com altitude média de 1500m e altitudes superiores que variam de 1784m, referente ao Morro da Lombada e 1722m ao Pico do Pião. A Serra do Ibitipoca representa um contraforte proeminente da Serra da Mantiqueira, e constitui-se em duas cristas aplainadas ao norte e arrasadas ao sul. No âmbito geológico, a Serra do Ibitipoca é constituída basicamente por quartzitos de granulometria grossa, intercalados por camadas de quartzitos finos micáceos e granada-sillimanita-biotita xisto. Os sedimentos que preencheram a bacia sedimentar original foram metamorfizados na fácies anfibolito, e deformados em regime tectônico compressivo, resultantes de uma evolução tipo nappe de dobra, com desenvolvimento subseqüente de sistemas de falhas e zonas de cisalhamento de alto ângulo. O resultado desta manifestação tectônica em ambiente sedimentar transicional continente-oceano, associado à atuação de processos erosivos, propiciou o desenvolvimento de quinze magníficas e peculiares grutas formadas em rochas quarzíticas, destacandose a Gruta das Bromélias com maior extensão.

    There is growing acknowledgment that research in the postconflict field needs to include a focus on social conditions. The authors applied structural equation modeling to epidemiologic data obtained from postconflict Timor-Leste, to examine for links involving potentially traumatic events and sociodemographic factors (age, gender, educational levels, and unemployment) with psychological symptoms and functioning. Exposure to trauma and lack of education emerged as most relevant with psychological distress impacting on education in the urban area. Age and gender exerted influences at different points in the model consistent with the known history of Timor. Although based on cross-sectional data, the model supports the relevance of past trauma, posttraumatic distress, and postconflict social conditions to functioning in societies such as Timor-Leste.

    Full Text Available The Lagoa das Flores Mine is an important iron ore deposit located at the Serra Azul complex in the Northwestern border of the Ferriferous Quadrangle, Minas Gerais, where other important mines also occur, such as Arcelor Mittal, Usiminas, MBL and MMX. Presently 2.2 Mt/year of waste are generated; 70% of this waste is comprised by compact itabirite whose mineral resource is of the order of 370 Mt. The goals are to perform a mineralogical characterization and the development of process routes for this ore type by bench scale testing. The latter was carried out by work index and abrasion index determinations and magnetic concentration, desliming and flotation testing. The ore was composed by quartz, martitic hematite and minor magnetite; the average iron content was 34.3% and the quartz liberation degree was 92% below 0.075 mm. The best processing route are grinding to –0.15 mm, followed by medium and high strength field magnetic concentration, regrinding to –0.053 mm and reverse cationic flotation. Therefore, a final concentrate with 67.8% Fe, 1.84% SiO2 contents and metallic recovery of 83% is obtained.

    The interruption of important phenological series and the progressive disappearance of phenological observations in Catalonia led the Meteorological Service of Catalonia (SMC) to design and impulse a new phenological network promoted by the Climate Change Unit of this Met Service. The "Fenocat" network was born in March 2013, and currently has around fifty observers distributed throughout Catalonia that observe plants, birds and butterflies. We are providing data from different plant phenophases to PEP725 database. Besides this new phenological network (Fenocat), one of the aims of SMC is to rescue and preserve historical data from different observation points in Catalonia. We show in this poster the example of rescue and preservation of phenological data from la Serra d'Almos (in Tivissa, near Tarragona, Catalonia, NE Iberian Peninsula), an observation series that began in 1973. After digitalization process and quality control tasks, we show preliminary results of this phenological series, and we compare them with those of similar European series. We show the evolution trends for different observed species, such as almond tree (Prunus dulcis), hazel (Corylus avellana), plum (Prunus domestica), olive tree (Olea europea), apple tree (Malus domestica) or vineyard (Vitis vinifera).

    Full Text Available The upper montane forests in the southern and southeastern regions of Brazil have an unusual and discontinuous geographic distribution at the top of the Atlantic coastal mountain ranges. To describe the floristic composition and structure of the Atlantic Forest near its upper altitudinal limit in southeastern Brazil, 30 plots with 10 × 10 m were installed in three forest sites between 2,200 and 2,300 m.a.s.l. at Serra Fina. The floristic composition and phytosociological structure of this forest were compared with other montane and upper montane forests. In total, 704 individuals were included, belonging to 24 species, 15 families, and 19 genera. Myrsinaceae, Myrtaceae, Symplocaceae, and Cunoniaceae were the most important families, and Myrsine gardneriana, Myrceugenia alpigena, Weinmannia humilis, and Symplocos corymboclados were the most important species. The three forest sites revealed differences in the abundance of species, density, canopy height, and number of stems per individual. The upper montane forests showed structural similarities, such as lower richness, diversity, and effective number of species, and they tended to have higher total densities and total dominance per hectare to montane forests. The most important species in these upper montane forests belong to Austral-Antartic genera or neotropical and pantropical genera that are typical of montane areas. The high number of species shared by these forests suggests past connections between the vegetation in southern Brazilian high-altitude areas.

    Full Text Available A Serra Gaúcha, mais especificamente os municípios de colonização italiana, desde o início do século XX é tida como a maior e mais conceituada área produtora de uva e de vinhos do Brasil. Nos últimos trinta anos, porém, uma série de mudanças afetou o mercado de vinhos, tornando-o mais competitivo e internacionalizado, levando as empresas ali instaladas a valorizar aspectos de sua produção que as diferenciassem e mantivessem sua posição de destaque no mercado nacional. Essa valorização do local e de suas particularidades, promovida num contexto de globalização neoliberal do capitalismo, resultou numa maior importância do turismo, que, neste momento e naquele lugar, passou a exercer um papel-chave, “azeitando” as engrenagens e ajudando no bom funcionamento do motor do capital. O presente artigo tem por objetivo principal fornecer um panorama geral acerca de algumas das recentes transformações socioespaciais advindas do turismo, em especial sobre as tentativas de fazer daquele espaço uma representação de si mesmo.

    Full Text Available This paper proposes a mapping of landforms units for the southern portion of the middle third of the Serra do Espinhaço Meridional. The landforms units were delineated from the integrated analysis of thematic maps and satellite images that allowed the observation of changes in morphology, altimetry, slope, lithostructure and organization of the drainage network. The step of digital mapping, processed in the software ArcGIS 9.2, was based in the use of SRTM products (Shuttle Radar Topography Mission. The methodological procedures also included field work and literature research. The taxonomy of geomorphological mapping proposed by IBGE (2009 was applied , through which fourteen Geomorphologycal Units were individualized. The units are distributed amongst five different compartments as follows: two plateaux, two escarpments, six depressions, three sets of ridges and one set of intermediate levels. It was observed that the general layout of the units reflects the strong lithostructural control forced to regional relief. The differentiated resistance of the various lithologies in relation to denudational processes and the influence of neotectonic on landscape evolution are noteworthy.

The research consisted of data collection of vegetation and sheep, in 38 hectares of Caatinga from a private farm. We evaluated the herbage mass, herbal chemical composition, botanical composition, bare soil, litter, plants height, stocking rate, animal performance and herbage allowance. Herbage mass ranged from 422 ± 42 to 1262 ± 95 kg DM.ha-1within the period January 2011 to January 2012, which led to decreased herbage allowance (13,1± 1,3 a 56,4± 4,2 kg MS.kg PV- 1 . The weight gain of sheep observed was 2.0 ± 2.2 kg. head-1 .period-1 and 3.8 ± 4.0 kg.ha-1 .period-1 . The litter during the dry season was higher in October 2011 (38.8 ± 4.1% and January 2012 (41.4 ± 4.3%. Increased values were observed on bare soil, mainly in dry season, averaging 24.4 ± 1.5%. With the advance of the dry season, the concentrations of DM, NDF, ADF and TC of pasture increased, while the CP, MM, and NFC decreased. In general, the Caatinga show varieties in the range of herbage mass, forage chemical composition, and animal performance, over the year.

    Full Text Available Serra do Mar emerged by erosional processes of Santos fault line to the Upper Cretaceous, in the present continental south-american platform. Santos fault line caused abatement of the plateau, which corresponds at Japi erosional surface. The scarp’s retreat of Serra do Mar caused the river capture of plateau’s rivers as Guaratuba, in Boracéia-SP. Alto Guaratuba basin is located at Parque Estadual da Serra do Mar, near Serra do Mar scarp, approximately at 45º 56’ and 45º 52’ of longitude west and 23º 38’ and 23º 42’ of latitude south. Guaratuba river flows from NE-SW on the plateau to N-S on the scarp and its change suggests that Guaratuba is captured by headward erosion, as result of Serra do Mar’s regressive erosion. Some evidences are found: the elbow of capture in a sharp change from NE-SW to N-S, cutting rocks’ structural lines, near the scarp; a wind gap swampy and gravelly, near the elbow of capture, as an ancient Guaratuba’s riverbed; river profile of Guaratuba as a powerful slope rupture.

    Full Text Available The augmented block design is widely used in breeding programs, with non-replicated treatments generally being selection units, and replicated treatments being standard cultivars. Originally, an intrablock analysis (fixed model was proposed. Although non-replicated treatments and/or blocks can be considered of random nature, mixed linear models could be used instead. This work evaluated such an approach, using computer simulation. Populations consisted of sets of randomly generated inbred lines. Molecular marker data were also simulated to allow the estimation of the genetic covariance matrix. Different conditions were considered, varying heritability and the coefficient b of Smith of soil heterogeneity. For each condition 100 simulations were performed, considering four linear models, varying respectively the nature of the effects of blocks and non-replicated treatments (fixed - F, or random - R: FF, FR, RF and RR. In relation to FF, the mixed models were more efficient under low to intermediate heritability and high b. Mixed models could improve inference in breeding programs using the augmented block design and the choice of the model should rely on the kind of selection. If this is truncated, the RF model should be preferred; if it is not, then the RR model would be more suitable.O delineamento em blocos aumentados é amplamente utilizado em programas de melhoramento, geralmente com tratamentos não-repetidos correspondentes a unidades de seleção, e tratamentos repetidos sendo cultivares comerciais. Originalmente, uma análise intrablocos (modelo fixo foi sugerida. No entanto, se os tratamentos não-repetidos e/ou blocos puderem ser considerados de natureza aleatória, modelos lineares mistos poderiam ser utilizados.

    One current strategy to overcome the issue of shortage of qualified health workers has focused on the use of community health workers in the developing countries to deliver health care services specifically to the most vulnerable communities in the rural areas. Timor-Leste is the one of the world's newest developing countries that has incorporated the traditional birth attendance in its health system through a family health promoter initiative in response to reproductive and child health, hence to improve primary health care delivery and increase number of healthcare workforce. The study utilized a non-systematic review of the literature using key words such as community health workers, traditional birth attendants, reproductive health, child health and health outcomes. A case study from Timor-Leste was also used. Traditional birth attendants have performed wide variety of tasks including outreach and case finding, health and patient education, referrals, home visits and care management. Evidence indicated that there were, to varying degrees, positive associations between traditional birth attendance training and maternity care. Traditional birth attendance training was found to be associated with significant increases in attributes such as knowledge, attitude, behavior, advice for antenatal care, and pregnancy outcomes. However, some challenges faced by traditional birth attendants' role in encouraging women to go to health center for preventive services would be the compliance and refusal of the referral. The implementation case study from Timor-Leste shows that integrating traditional birth attendance into a national healthcare system through Family Health Promoter program has been programmatic effective. It is recommended that the implementation should consider regular communication between health staff and community leaders in recruiting members of family health promoters, and the use of supportive supervision tools to identify weaknesses in the management of

    Full Text Available The Campina Grande and Serra Redonda Granites are intrusive along the contact of the Paleoproterozoic basement(Alto Moxotó Domain with the Tonian gneisses (Alto Pajeú Domain of the Borborema Province (northeast Brazil. TheCampina Grande Granite (U-Pb age = 581± 2 Ma shows a concentric oval-shaped structure whereas the Serra RedondaGranite (U-Pb age = 576 ± 3 Ma has a tabular shape, elongated in the NE-SW direction. The plutons are separated bythe left-lateral Galante transcurrent shear zone. In this study, the anisotropy of magnetic susceptibility (AMS was appliedto 64 outcrops of granites to determine the internal structures of these plutons and to explore the relationship betweenmagmatism and deformation in an orogenic setting. The magnetic fabrics are concordant with the metamorphic structure ofthe host rocks. Strike-slip shear zones controlled the emplacement of the Serra Redonda Granite, as indicated by sigmoidalfoliation, defining shear bands associated with the Galante shear zone. In contrast, the magmatic/magnetic fabric of theCampina Grande granite seems to have been produced by body (ascensional forces. The pluton displays an inward dipping, concentric planar fabric parallel to the wall rock contact and lineations highly oblique to the foliation trend. The fabric of the Campina Grande pluton is consistent with a magma moving over a ramp dipping to southwest, with the lineation at high angle to the NE-trending flow direction. The contrasting structures of the plutons reflect the episodic nature of orogenic deformation, which was punctuated by the alternation of weak and strong strains, affecting the fabric development of the syntectonic intrusions.

    The most substantial and best preserved area of Atlantic Forest is within the biogeographical sub-region of Serra do Mar. The topographic complexity of the region creates a diverse array of microclimates, which can affect species distribution and diversity inside the forest. Given that Atlantic Forest includes highly heterogeneous environments, a diverse and medically important Culicidae assemblage, and possible species co-occurrence, we evaluated mosquito assemblages from bromeliad phytotelmata in Serra do Mar (southeastern Brazil). Larvae and pupae were collected monthly from Nidularium and Vriesea bromeliads between July 2008 and June 2009. Collection sites were divided into landscape categories (lowland, hillslope and hilltop) based on elevation and slope. Correlations between bromeliad mosquito assemblage and environmental variables were assessed using multivariate redundancy analysis. Differences in species diversity between bromeliads within each category of elevation were explored using the Renyi diversity index. Univariate binary logistic regression analyses were used to assess species co-occurrence. A total of 2,024 mosquitoes belonging to 22 species were collected. Landscape categories (pseudo-F value = 1.89, p = 0.04), bromeliad water volume (pseudo-F = 2.99, p = 0.03) and bromeliad fullness (Pseudo-F = 4.47, p mosquito assemblage structure. Renyi diversity index show that lowland possesses the highest diversity indices. The presence of An. homunculus was associated with Cx. ocellatus and the presence of An. cruzii was associated with Cx. neglectus, Cx. inimitabilis fuscatus and Cx. worontzowi. Anopheles cruzii and An. homunculus were taken from the same bromeliad, however, the co-occurrence between those two species was not statistically significant. One of the main findings of our study was that differences in species among mosquito assemblages were influenced by landscape characteristics.

    Full Text Available It is recognized that international water sector development work has issues with a lack of sustained positive outcomes. A large driver of this outcome is how NGOs work with communities to implement and then manage water services. Many NGOs tend to focus their efforts on improving their reach and organisational growth by continually engaging in new projects. This behaviour is largely driven by short-term donor funding models that reward extended coverage, leaving little focus on sustained outcomes. Similarly, community-based management (CBM schemes often impede sustained services as a result of the community’s limited capacity to operate and maintain the technology. To explore these complicated drivers on water service sustainability, we used causal loop diagramming to analyse the key aspect influencing the combined dynamics between NGOs, donors and CBM. We demonstrate this methodology through a study in Timor-Leste, where we gathered data necessary to develop and apply causal loop diagrams to analyse rural water supply program outcomes. The analysis of these diagrams allowed identification of leverage points used to suggest structural changes for sustained benefits of water services. These structural changes emphasize the importance of increased robustness and reliability of water technology and the associated impact this has on community satisfaction and, conjointly, on water service sustainability.

    It is important to define subpopulations with mental health and psychosocial reactions in the medium-term following conflict to ensure that an appropriate array of services are provided to meet the diversity of needs. We conducted a latent class analysis (LCA) on epidemiological data drawn from an urban and rural sample of 1221 adults (581 men and 640 women, response 82%) in post-conflict Timor Leste 4 years after the cessation of violence. The prevalence of PTSD was 4.9%; severe distress 4.8%; anger attacks 38.3%; and paranoid-like symptoms 10.9%. The best fitting LCA yielded three classes comprising those with no or minimal symptoms (86%), a class with anger-paranoia (13%) and a comorbid mental disorder class (1.5%) characterized by PTSD (100%) and severe distress (98%). The comorbid mental disorder class had an over-representation of men, the unemployed, residents in the urban area and persons with the greatest exposure to human rights trauma, murder and health stress. The anger-paranoia class experienced moderate levels of trauma and had an over-representation of urban dwellers, women, and those with higher levels of education. The analysis assists in clarifying the populations with mental disorder and adverse psychosocial reactions in need of intervention in the medium-term following conflict.

    Egg deposition within plants is one of the most widely distributed and ancient behaviors in Odonata. The resulting clutch consists of eggs placed in peculiar pattern that can be a characteristic for certain groups of Odonata. Despite their importance for paleontological and evolutionary research, data on egg-clutch positioning are missing or insufficient for most species. Here, patterning of egg clutches in Lestes virens was measured and described in detail for the first time. The female usually produces a linear row of single eggs directed at an angle rightward or leftward to the longitudinal axis of plant substrate. Less often eggs are arranged in egg-sets consisting of up to 4 eggs. Apparently, the female insect follows the rigid behavior stereotypes during oviposition and is unable to easily switch to the alternate stereotypical behavior of single egg deposition or production of multiegg sets. Based on a literature review and original data, egg clutch patterning of European Lestidae is overlaid on preexisting phylogenies. The resulting evolutionary scenario of egg-clutch patterning can be considered in the framework of egg-laying behavior in Lestidae.

    Full Text Available This article aims to rescue the historical data of the introduction of rainbow trout in the socio-spatial context of the Sierra Santa Catarina, particularly URUBICI / SC municipality. Despite being a kind associated with economic benefits, the process of introduction of trout Oncorhynchus mykiss often has brought environmental and socioeconomic damage whose effects are still unknown. Trout was introduced in Brazil for the first time in 1949 in the Serra da Bocaina (MG and Southeast. The main reasons for its introduction in Brazilian rivers have been the increase in and Rio Macae (RJ in 1952. Currently, the species can now be found in all the states of the South sport fishing and tourism, often on the grounds of alleged lack of other species of fish in the rivers, as happened for example in Sierra Santa Catarina. More recently the Law nº1098 by prohibiting the creation of exotic species in Brazilian rivers included the trout which was later also excluded from this relationship that allowed the creation of this kind continue to occur. Although historically trout has been introduced by government initiative, and the legislation has been lenient, the main supporters of this activity, now are businessmen in the tourist industry and anglers. The trout farming has also been practiced for sale of live specimens, without obtaining the environmental license. Restrictive environmental standards are very recent and little publicized. Impact assessment studies on the native fauna to support educational campaigns and to propose measures for handling and marketing Trout are recommended actions.

    Full Text Available In the southern escarpment of the Serra da Mantiqueira, northeast geographic divider between the State of São Paulo and Minas Gerais, there was an environmental accident caused by the disruption of an adductor whose purpose is to lead the water from a reservoir located at an altitude of 1820 m to the machine house where there is an electric generator located at 750 m.  This accident resulted in the formation of a scar on the hillside forest, with removal of soil and vegetation. To reverse the erosion processes, a methodology was developed consisting of the use of four barriers (numbered I to IV formed by seedlings of Bambusa mutiplex (Lour., whose purpose was to divert the water runoff in order to provide the regeneration of native vegetation. Stalks of bamboo intercropped with Bambusa multiplex were used to contain debris in two gullies formed by erosion. The development of vegetation was monitored for 18 months and evaluated by the application of a Leopold Matrix composed of 5 points, which are: erosion, regeneration of vegetation, success of bamboo planting, installed conservation structures and functionality. The purpose of the matrix was to demonstrate the effectiveness of interventions using bamboo. The result of the classification matrix enabled the quantitative and qualitative classification of the interventions, resulting in five levels, where the barriers I, II and IV were considered to be of very high efficiency, and barrier III was considered to be of high efficiency. The contention of the gully was considered to be of medium to very high efficiency.

    Full Text Available Serra da Tiririca State Park (Parque Estadual da Serra da Tiririca-PESET is located in an area of rich environmental history between the cities of Niterói and Maricá in Rio de Janeiro State, Brazil. Established through grassroots lobbying and popular mobilization, it nevertheless hosted some mistakes that catalyzed social problems, which should have been otherwise dealt with during its creation process. We believe that social representations allow us to learn about the symbolic sphere of the social insertion of protected areas. On the one hand, the protected area is seen as a “paper park” and as a stage where confl icts related to real-estate speculation, land ownership and the political situation take place. Its positive image, on the other hand, refers to the political mobilization for its creation and to the community’s vigilance. As a conclusion, the social representations must be understood so that its positive aspects maybe highlighted, contribute to its regional incorporation and aid in the Park’s management.

    Full Text Available A dissecção individualizada das estruturas do hilo pulmonar para execução de ressecções pulmonares nem sempre é de fácil execução. Nas operações vídeo-assistidas, as dificuldades de dissecção podem impedir a ressecção por essa via, obrigando o cirurgião a converter o procedimento operatório a aberto. As melhoras da qualidade técnica dos grampeadores cirúrgicos na década de 90 foram tão importantes que começam a surgir questionamentos quanto a sua possível eficiência na sutura em bloco das estruturas do hilo pulmonar, dispensando, assim, a dissecção individualizada de seus componentes, para a realização das ressecções. O objetivo de nosso trabalho foi verificar o efeito da sutura mecânica em bloco do hilo pulmonar. Realizamos pneumectomia em 12 cães machos, adultos, mestiços, com sutura simultânea do hilo pulmonar que foram distribuídos aleatoriamente em dois grupos com seis animais cada, observados até o 7º e 14 º dias de pós-operatório, obedecendo a protocolos experimentais previamente elaborados de verificação da macro e microscopia. A via de acesso foi a toracotomia lateral, realizada no animal anestesiado e mantido em ventilação controlada por ventilador mecânico. A sutura do hilo pulmonar em bloco foi realizada com somente um disparo do grampeador linear cortante de 60mm. Não houve a ocorrência de óbitos, deiscências de sutura ou fístulas arteriais ou venosas. Um animal apresentou abscesso no coto de amputação sem, entretanto, desenvolver fistulas ou deiscências nas suturas. A evolução pós-operatória foi considerada boa em 10 (83,3% dos animais e regular em 2 (16,7%, que apresentaram pequenos abscessos incisionais. Concluímos que esta técnica de sutura é viável, de rápida execução, apresenta bons resultados e necessita de estudos complementares que os corroborem.Individualized dissections of lung hilum structures to perform lung resections are not always easy.

    Full Text Available Este artigo examina as relações entre o discurso da justiça e a prática do ritual nos bandos do governo colonial português em Timor Leste, entre a segunda metade do século XIX e as primeiras décadas do século XX. Os bandos consistiam em ordens e instruções de comando emanadas pelo governador português em Díli, e comunicadas de forma cerimonial por oficiais às populações dos diversos reinos timorenses dispersos pelo país. Bandos eram um instrumento por excelência de governação colonial dos assuntos indígenas, servindo para arbitrar conflitos, punir transgressões e, em geral, instituir realidades no mundo timorense. Contudo, esta instituição assumiu igualmente uma singular expressão nos usos timorenses, servindo bandos para comunicar também as ordens de autoridades tradicionais, os liurais. O artigo acompanha as variações coloniais e indígenas que os bandos adquiriram em Timor Leste, conceptualizando-os enquanto colectivos de justiça. Ao considerar assim os bandos como colectivos - formações heterogéneas em que elementos linguísticos e não linguísticos se combinam na produção de efeitos de poder sobre as populações - o artigo propõe uma via conceptual alternativa às perspectivas linguísticas e literárias de análise do discurso colonial.This article examines the relations between juridical discourse and ritual practice in the bandos issued by the Portuguese colonial government in East Timor between the second-half of the nineteenth century and the early decades of the twentieth century. Bandos consisted of orders and instructions of command issued by the Portuguese governor in Dilly and ceremonially transmitted by colonial officers to the populations of the various Timorese kingdoms. Bandos were a principal tool of colonial governance with regards to indigenous matters. They were used by the Portuguese to arbitrate conflicts, punish transgressions and, generally, to institute realities in the Timorese

    Full Text Available We inventoried the birds from Serra do Aracá region, state of Amazonas. The region encompasses a high diversity of vegetation types, including white sand forests and campinas, terra firme and flooded forests, montane forests and tepuis. We recorded 416 bird taxa in 69 families through captures with mist nets, tape recording of bird voices, and collection of voucher specimens. A large proportion of them (61% were recorded in a single vegetation type. Qualitative estimates suggest that approximately 580 bird species occur in the region. The avifauna of the Aracá region has a mixed biogeographic composition, with species typical of both margins of the Rio Negro occurring sympatrically. Additionally, species whose distributions are restricted to three areas of endemism for Amazonian birds (Imeri, Guiana and Pantepui were recorded in the region. Rare landscapes in the Brazilian Amazon are found in the Serra do Aracá region. Additionally, we recorded endemic and rare birds, highlighting the value of the region for conservation. The Serra do Aracá State Park officially protects montane forests, terra firme forests and tepuis. We suggest that the large extension of white sand campinas and igapó forests at the southern portion of Serra do Aracá should be also preserved in order to improve the representation of the rich natural heritage of the region.

    Benthic microbial metabolism and bacterial diagenetic pathways were measured along the southern shelf of Timor-Leste during an upwelling event in the winter SE monsoon season. Vertical profiles of water properties and bottom water nutrient concentrations, and operational ocean modeling showed subsurface upwelling from the Indonesian Throughflow (ITF) along the southern shelf west of longitude 126°25'E and surface upwelling at the far eastern end of the shelf. Warm surface waters above the halocline had salinities of 33.6 to 33.9 overlying cooler ITF water with salinities of 34.4 to 34.6. Beneath the zone of subsurface upwelling and stratification, sediment chlorophyll a (range: 2.8-4.4 µg g-1) and phaeopigment (range: 4.5-7.0 µg g-1) concentrations were sufficient to fuel very rapid rates of benthic oxygen consumption (range: 89.9-142.3 mmol m-2 day-1) and dissolved inorganic carbon (DIC) release (range: 108.1-148.9 mmol m-2 day-1) across the sediment-water interface, and DIC (range: 94.7-142.5 mmol m-2 day-1) and NH4+ (range: 13.3-19.9 mmol m-2 day-1) production from incubated surface (0-10 cm) sediments. Molar ratios of DIC/NH4+ production were lower (range: 6.6-7.7) in fine-grained sediments under the subsurface upwelling regime than in sandy, possibly scoured sediments under surface upwelling (range: 11.9-21.2) where there was no evidence of benthic enrichment. It is proposed that subsurface upwelling along the widest portions of the shelf stimulates phytoplankton production, leading to deposition of fresh phytodetritus that is rapidly decomposed on the seafloor. These zones of high biological activity may attract and support large populations of pelagic fish and cetaceans that have been caught for centuries along the south coast.

    Post-traumatic stress disorder (PTSD) is the most widely assessed form of mental distress in cross-cultural studies conducted amongst populations exposed to mass conflict and displacement. Nevertheless, there have been longstanding concerns about the universality of PTSD as a diagnostic category when applied across cultures. One approach to examining this question is to assess whether the same factor structure can be identified in culturally diverse populations as has been described in populations of western societies. We examine this issue based on an analysis of the Harvard Trauma Questionnaire (HTQ) completed by a large community sample in conflict-affected Timor-Leste. Culturally adapted measures were applied to assess exposure to conflict-related traumatic events (TEs), ongoing adversities, symptoms of PTSD and psychological distress, and functional impairment amongst a large population sample (n = 2964, response rate: 82.4%) in post-conflict Timor-Leste. Confirmatory factor analyses of the ICD-10, ICD-11, DSM-IV, four-factor Emotional Numbing and five-factor Dysphoric-Arousal PTSD structures, found considerable support for all these models. Based on these classifications, concurrent validity was indicated by logistic regression analyses which showed that being a woman, trauma exposure, ongoing adversity, severe distress, and functional impairment were all associated with PTSD. Although symptom prevalence estimates varied widely based on different classifications, our study found a general agreement in PTSD assignments across contemporary diagnostic systems in a large conflict-affected population in Timor-Leste. Further studies are needed, however, to establish the construct and concurrent validity of PTSD in other cultures.

  1. Ore mineralogy of the Serra Pelada Au-Pd-Pt deposit, Carajás, Brazil and implications for ore-forming processes

    Serra Pelada is a world-class hydrothermal Au-Pd-Pt deposit located at the eastern border of the Amazon craton, northern Brazil. The rocks at Serra Pelada have experienced intense tropical weathering for about 70 Ma, but drill core samples preserve the primary mineralogy and hydrothermal alteration features, with extreme grades of Au, Pd and Pt individually reaching hundreds of parts per million (ppm) by weight. Mineralization at Serra Pelada occurs in hydrothermally altered metasiltstones and dolomitic metasandstones at the hinge zone of a recumbent syncline, comprising zones of hematite, chlorite-carbon, argillic, and siliceous alteration. The main hydrothermal gangue minerals are quartz, kaolinite, sericite, amesite, hematite, monazite, florencite and variable amounts of highly reflective carbonaceous matter. Hydrothermal carbon input is evident from precipitated carbon occurring along crenulation planes and veinlets associated with the precious metals. Ore and accessory minerals include a variety of sulphide, selenide, arsenide, sulphate and oxide minerals, including gold with variable metal contents, palladian gold, fischesserite, sudovikovite, sperrylite, selenian braggite, isomertieite, mertieite-II and secondary Au-Pt-Pd alloys. The composition of fischesserite varies from the ideal formula (Ag3AuSe2) towards a more Ag-rich composition, indicating a disordered solid solution form that is stable only above 260 °C, consistent with the high thermal maturity of associated carbonaceous matter approaching graphite. Primary ore and gangue minerals at Serra Pelada comprise a suite of elements that are best transported in oxidising conditions and precipitated upon reduction. This suggests that fluid mixing between a highly oxidised (metal carrier) and a reduced fluid was a key process for high-grade noble metal precipitation at Serra Pelada.

A investigação foi realizada na Serra Gaúcha, extremo sul do Brasil, hoje uma das mais pujantes regiões de turismo do país que, na primeira metade do século XX – período rememorado pelos entrevistados – ainda apresentava precariedades na sua infra-estrutura de transportes. A partir de reflexões teóricas sobre a questão da memória analisam-se, especificamente, os relatos dos idosos em termos de viagens por eles realizadas na sua juventude. Os entrevistados, na sua totalidade ítalo-descendente de origem rural, diferenciam nos seus relatos as viagens ocorridas na infância, daquelas realizadas na juventude e na idade adulta. Os participantes do estudo avaliaram o momento presente como o mais qualificado e diferenciado dos anteriores, em termos de desfrute do lazer e das viagens que realizam. As respostas também encaminham uma série de dados que contribuem para a construção da história das viagens e do turismo no Brasil.

    In this work, results on studies carried out on radioactive samples from Serra do Sossego (close to Carajas , in the state of Para) are reported. According to studies of mineralogical characterization, involving petrographic and mineralographic analysis, complemented by other specific techniques, it was possible to determine the forms of presentation of the uraninite (UO{sub 2}), and its respective association to sulphide minerals rich in copper, primarily those with greater concentration, such as bornite (Cu{sub 5}FeS{sub 4}) and, secondarily, calcopirite (CuFeS{sub 2}). These sulphides come associated to abundant iron oxide, such as magnetite (Fe{sub 3}O{sub 4}) and its alteration products, and also assorted silicate minerals. From the results of autoradiographic tests and an electronic microprobe, a significant amount of uraninite was determined, showing that sulfites and oxides that occur associated to the uranium mineral, include this element in their crystalline lattices.

This has led to the finding of a number of very interesting frogs which do not occur in the lower, mesic, or, occasionally, xeric, open country. One of these forms is presented here. As it did not fit perfectly into any of the known genera, she decided to consult her fellow herpetologist at the National Museum, Mr. Antenor Leitão de Carvalho, who is interested in anatomy. He cleared an adult and a juvenille specimen; the osteological characters found are given below. Joint publication was decided upon, one author contributing her field-notes and the morphological characters and drafting the text, whereas the other contributed the osteology, drawings and measurements. The specific name was also chosen by Leitão de Carvalho, in homage to the late Professor Adolpho Lutz, a pioneer in the study of Brazilian frogs.

    Two new records of Anopheles homunculus in the eastern part of the Atlantic Forest are reported. This species was found for the first time in Barra do Ouro district, Maquiné municipality, Rio Grande do Sul state, located in the southern limit of the Atlantic Forest. The 2nd new record was in the Serra Bonita Reserve, Camacan municipality, southeast Bahia state. These records extend the geographical distribution of An. homunculus, suggesting that the species may be widely distributed in coastal areas of the Atlantic Forest. It is hypothesized that the disjunct distribution of the species may be caused by inadequate sampling, and also difficulties in species identification based only on female external characteristics. Species identification was based on morphological characters of the male, larva, and pupa, and corroborated by DNA sequence analyses, employing data from both 2nd internal transcribed spacer of nuclear ribosomal DNA and of mitochondrial cytochrome c oxidase subunit I.

Using fieldwork, petrography, and remote sensing imagery, we characterize the geology of the plutons in the region. Five individual plutons were recognized. Two correspond to the previously defined Marumbi and Anhangava Plutons. We divide the former "Graciosa Pluton" into three new plutons: Capivari, Órgãos, and Farinha Seca. The plutons are elliptical with northeast-southwest orientation. Two petrographic associations can be recognized: an alkaline association that includes peralkaline and metaluminous hypersolvus alkalifeldspar granites and syenites (Anhangava, Farinha Seca, Órgãos, and an aluminous association composed of metaluminous and weakly peraluminous subsolvus granites (Capivari, Órgãos, Anhangava, Marumbi. Occurrences of each association are limited to one individual pluton or to portions of a pluton, and the age relationships are not well established. Monzodioritic rocks are found marginal to the Órgãos and Farinha Seca Plutons, and interaction with silicic magmas locally produced hybrid quartz syenites (Farinha Seca Pluton.

    Enhancement techniques and thematic classifications were applied to the metasediments of Bambui Super Group (Upper Proterozoic) in the Region of Serra do Ramalho, SW of the state of Bahia. Linear contrast stretch, band-ratios with contrast stretch, and color-composites allow lithological discriminations. The effects of human activities and of vegetation cover mask and limit, in several ways, the lithological discrimination with digital MSS data. Principal component images and color composite of linear contrast stretch of these products, show lithological discrimination through tonal gradations. This set of products allows the delineations of several metasedimentary sequences to a level superior to reconnaissance mapping. Supervised (maximum likelihood classifier) and nonsupervised (K-Means classifier) classification of the limestone sequence, host to fluorite mineralization show satisfactory results.

    We have elucidated the carbohydrate-binding profile of a non-monosaccharide-binding lectin named Eucheuma serra lectin (ESA)-2 from the red alga Eucheuma serra using a lectin-immobilized column and a centrifugal ultrafiltration-high performance liquid chromatography method with a variety of fluorescence-labeled oligosaccharides. In both methods, ESA-2 exclusively bound with high-mannose type (HM) N-glycans, but not with any of other N-glycans including complex type, hybrid type and core pentasaccharides, and oligosaccharides from glycolipids. These findings indicate that ESA-2 recognizes the branched oligomannosides of the N-glycans. However, ESA-2 did not bind with any of the free oligomannoses examined that are constituents of the branched oligomannosides implying that the portion of the core N-acetyl-D-glucosamine (GlcNAc) residue(s) of the N-glycans is also essential for binding. Thus, the algal lectin was strictly specific for HM N-glycans and recognized the extended carbohydrate structure with a minimum size of the pentasaccharide, Man(alpha1-3)Man(alpha1-6)Man(beta1-4)GlcNAc(beta1-4) GlcNAc. Kinetic analysis of binding with a HM heptasaccharide (M5) showed that ESA-2 has four carbohydrate-binding sites per polypeptide with a high association constant of 1.6x10(8) M-1. Sequence analysis, by a combination of Edman degradation and mass analyses of the intact protein and of peptides produced by its enzymic digestions, showed that ESA-2 is composed of 268 amino acids (molecular weight 27950) with four tandemly repeated domains of 67 amino acids. The number of repeats coincided with the number of carbohydrate-binding sites in the monomeric molecule. Surprisingly, the marine algal lectin was homologous to hemagglutinin from the soil bacterium Myxococcus xanthus.

    Full Text Available A Chironomidae (Diptera fauna list for headwater streams of high altitude areas in Serra da Estrela (Portugal is presented, doubling the previously established species richness for the region. The findings include 17 new records for Portugal, which represent an increase to 219 species for the Continental Portugal Chironomidae fauna. Two new records were detected for the Iberian Peninsula: one species (Tvetenia duodenaria, and one subgenus –Psectrocladius (Mesopsectrocladius–; and the presence of the genus Natarsia is confirmed. The last two occurrences correspond to monoespecific taxa of the Palearctic region. However, as taxonomic identification has been based on larval material, instead of pupae, pupal exuviae or imagoes, species level assignment is still uncertain.

    Se presenta una lista de especies de Chironomidae (Diptera recolectadas en los ríos de cabecera de zonas de alta montaña en la Serra da Estrela (Portugal. Con esta aportación se duplica la riqueza de especies regional conocida hasta el momento y se eleva la fauna de quironómidos del Portugal continental a 219 especies. Se incluyen dos nuevas citas para la Península Ibérica, una especie (Tvetenia duodenaria y un subgénero –Psectrocladius (Mesopsectrocladius–, y se confirma la presencia del género Natarsia. En los dos últimos casos se trata de larvas de taxones hasta el momento monoespecíficos en la región paleárctica, pero al no haberse recolectado pupas o adultos no se puede asegurar la identificación específica.

Entretanto, nem todas as pessoas se beneficiam com a atividade, como deficientes e pessoas com mobilidade reduzida, pois não podem usufruir dos espaços e atrativos turísticos devido à falta de adaptações. Assim, esta pesquisa tem como objetivo discutir e analisar a infraestrutura do Parque Nacional Serra da Capivara – PI, Patrimônio Cultural brasileiro, no que diz respeito à acessibilidade. Para tanto, realizou-se uma pesquisa bibliográfica sobre o tema e em uma pesquisa de campo, durante os meses de julho a setembro de 2010, com observação direta da área, coleta de dados, entrevistas e conversas informais. Percebeu-se, então, que a infraestrutura do Parque possui algumas adaptações, destinadas principalmente a cadeirantes, mas de maneira superficial e em alguns casos, incorreta.Palavras-chave: turismo acessível; unidade de conservação; deficiência. AbstractTourism provides many benefits for both as destinations for people who practice it.

    Serra da Estrela Protected Designation of Origin (PDO) cheese is the most famous Portuguese cheese and has a high commercial value. However, the adulteration of production with cheaper/lower-quality milks from non-autochthones ovine breeds compromises the quality of the final product and undervalues the original PDO cheese. A Randomly Amplified Polymorphic DNA (RAPD) method was developed for efficient detection of adulterant breeds in milk mixtures used for fraudulent production of this cheese. Furthermore, Sequence Characterized Amplified Region (SCAR) markers were designed envisioning the detection of milk adulteration in processed dairy foods. The RAPD-SCAR technique is here described, for the first time, to be potentially useful for detection of milk origin in dairy products. In this sense, our findings will play an important role on the valorization of Serra da Estrela cheese, as well as on other high-quality dairy products prone to adulteration, contributing to the further development of the dairy industry.

    Full Text Available Com o aumento da população nos últimos anos, a indústria de modo geral tem se adequado à demanda resultante. A indústria do processo de recauchutagem de pneus gera resíduos que em sua maioria têm sido descartados sem nenhum controle. Este fato contribui para aumentar a poluição ambiental e favorecer a proliferação de vetores nocivos à saúde. Visando encontrar uma aplicação para esse tipo de resíduo, neste trabalho serão apresentados resultados experimentais de blocos intertravados para pavimentos de concreto, com traços adicionados de resíduos de pneus. Foram confeccionados blocos intertravados em que se determinou, por meio de ensaios laboratoriais, a necessidade de se fixar o traço que desse maior retorno quanto às características analisadas. Verificaram-se quatro tipos de traços de concreto com resíduos de pneus. Procedeu-se aos ensaios de resistência mecânica à compressão, absorção de água e resistência ao impacto. Pelos resultados preliminares obtidos, verificou-se que são satisfatórios, confirmando-se a possibilidade de aplicação desse tipo de bloco intertravado em ambientes com solicitações baixas, o que traria, além da economia das fontes naturais de agregados, benefícios ecológicos pela reutilização dos resíduos da recauchutagem de pneus.

    One of the fundamental problems to understanding the evolution of volcano-sedimentary sequences in southeastern Brazil is constraining their depositional ages. Brasiliano tectonic and metamorphic either obscured or destroyed primary features, such as unconformities, as well as other geologic relationships. This problem is exemplified by the Serra do Itaberaba and Sao Roque groups, where the lack of data about the timing of their deposition has prevented resolution of proposed one-and two-stage geotectonic/depositional models. Recent U-Pb zircon data obtained from metavolcanic rocks in the Sao Roque Group indicate that it was deposited between 628 and 607 Ma. New U-Pb zircon data of 1395{+-} 10 Ma for a metandesite in the basal Morro da Pedra Preta Formation (Serra do Itaberaba Group) indicate the maximum age for the beginning of the deposition of the pelites overlying MORB-like basalt. A metarhyolite of the upper unit, the Nhangucu Formation, contains two zircon populations. One yielded an age of 619 {+-}3 Ma, which defines the crystallization age of the rock, and the other an age of 1449 {+-}3 Ma, interpreted as inherited xenocrystal grains from older units of the Serra do Itaberaba Group. The younger metarhyolite was affected only by the S{sub 2} foliation, generated during the Brasiliano orogenesis, whereas the Middle Proterozoic metavolcano-sedimentary sequence records additional metamorphic and deformational events, confirming the presence of two different geotectonic cycles.

    Full Text Available Serra do Cipó has attracted the interest of many researchers over the years because of its unique characteristics, particularly the fact that the site represents the transition between Cerrado and Atlantic Forest. The study area of Serra do Cipó is located along a gallery forest "córrego Três Pontinhas," at 19°16'00" S and 43°32'49" W and an altitude of 1,188 m. The objective of this study was to survey the Division Bryophyta in a gallery forest within the National Park of Serra do Cipo, Minas Gerais. Collections were made during the months of November 2009 and July 2011. We found 15 families, 26 genera, 43 species, and 4 varieties of mosses. The families with the largest number of species were Leucobryaceae (10, Sematophyllaceae (9, and Calymperaceae (6. Other families included Fissidentaceae (3, Bryaceae, Pylaisiadelphaceae, Pottiaceae, and Orthotrichaceae (2 spp. each; Brachytheciaceae, Cryphaeaceae, Fabroniaceae, Helicophyllaceae, Hypnaceae, Polytrichaceae, and Sphagnaceae had only 1 sp. each.

    Volatiles in Rabdosia serra were investigated by headspace solid phase microextraction (HS-SPME) and simultaneous-distillation extraction (SDE). The HS-SPME technique was previously evaluated to optimise sampling conditions. A total of 56 and 48 compounds including alcohols, aldehydes, hydrocarbons, ketones, carboxylic acid, ester, and aromatics were identified in leaf and stem by optimised HS-SPME method (CAR/PDMS fibre; incubation time, 10 min; extraction temperature, 50°C; extraction time, 40 min), respectively. 1-Octen-3-ol and (2E)-hexenal had significant contribution to R. serra aroma. Cluster analysis indicated that leaf and stem exhibited different volatile diversity. Air drying was favourable for the retention of the volatiles, while freeze- and sun-drying led to the loss of volatiles. SDE method preferred to the analysis of compounds with low volatility including fatty acids and esters. HS-SPME was a useful technique for the analysis of readily volatile components for the characteristics of R. serra aroma.

    The Serra da Canastra region, located in southwestern Minas Gerais, Brazil, is recognized worldwide for its tradition of producing artisanal cheeses. However, as production is done by hand, great variability exists in the characteristics of artisanal Minas cheese. Thus, it is important to characterize the sensory profile of these products and verify the quality attributes that lead to their acceptance. Therefore, this study aimed to characterize the dynamic sensorial profile of artisanal Minas cheese produced in the Serra da Canastra region through temporal dominance of sensations and sensory acceptance tests and verify the attributes that lead to product quality. We observed that the texture and flavor profile varied among the evaluated artisanal Minas cheeses from Serra da Canastra, some cheeses being more characterized by creamy and soft or hard and firm sensations, whereas others had high dominance rates for crumbly texture. In relation to flavor, salty and bitter tastes were dominant in most cheeses, some also being characterized by a sour taste, and others by buttery and rancid attributes, which indicates a lack of product standardization. However, all samples obtained scores between 6 (liked slightly) and 7 (liked moderately), indicating good acceptability in relation to the texture and flavor of the evaluated cheeses. Moreover, it is possible to infer that creamy and soft or hard and firm are positive attributes for cheese texture, and bitter, buttery, salty, and acid taste drive cheese acceptance. This study provides important information for product standardization, quality improvement, and process origin indications, besides providing quality attributes that meet consumer desires.

    2010-05-01

    The Serra do Moradal-Fajão syncline is a major NNW-SSE Variscan structure developed in the SW sector of the Centro-Iberian Zone, one of the main geodynamical structures of the Iberian Variscides. This tight syncline with a 1.5 km wavelength, could be followed for more than 80 km and represents one of the most important regional structures. Its complex structure has been possible to characterize, not only due to excellent outcrop condition (mostly induced by the competent behaviour of the Lower Ordovician Armorican Quartzite Formation), but also to the detailed lithostratigraphic control of the Ordovician-Silurian lithologies. These units are present in a homogeneous regional distribution, unconformably overlain the Cambrian Beiras Group. Concerning the Variscan structures, their geometry and kinematics show that they could be ascribed to progressive deformation induced by the first and main D1 tectonic event. During this event, a complex NNW-SSE aggregation of fold and thrust arrays have been developed. At the macroscale, this pattern is mainly characterized by the Serra de Moradal-Fajão syncline. Both limbs of this major D1 Variscan fold, which present a slightly ENE facing, have been disrupted by convergent thrust systems, leading to the superposition of the Cambrian Beiras metasediments on top of the Ordovician-Silurian succession. Concerning its SW limb, a major single overthrust has been developed, the Vilar Barroco-Fajão one, although in some very localized sectors, some minor thrusts could be emphasized; as they present a ENE facing, they are interpreted as duplex style forethrusts in relation to the main overthrust. Regarding the NE limb, a different behaviour is found. Indeed, in this sector, an imbricated thrust system has been mapped; due to their WSW facing it should be considered as backthrusts. Concerning the temporal relations between the previously described structures, although in some rare cases backthrusts cut forethrusts, the scarcity of

    The purpose of this paper is to describe and analyse the professional expectations and profile of medical students at the Cuban-supported School of General Medicine, in the Faculty of Medicine and Health Sciences of the National University of Timor-Leste. A piloted, standardized questionnaire, with closed- and open-ended questions, was distributed to registered medical students attending classes on the day of the survey. All data were analysed using SPSS. The statistical analysis is mostly descriptive. Students decide to study medicine at an early age. Relatives and friends seem to have an especially important influence in encouraging, reinforcing and promoting the desire to be a doctor. The degree of feminization of the student population is high. Medical students are in general satisfied with the training received, though demanding improvements in terms of systems to support their studies and training (e.g. libraries, laboratories, access to computers and the Internet). Medical students know that they will be needed in the public sector and that it would represent their opportunity to contribute to the public's welfare. Nonetheless, they report that they expect to combine public sector practice with private work, probably, in order to improve their earnings. This may be explained by their expectations for salaries, which are much higher than the current level of public sector salaries. A significant proportion of students are unsure about their future area of specialization. Of those that have determined their desired specialization, most intend to train as hospital specialists and to follow a hospital-based career. For many, specialization is equated with migration to study abroad. There are important differences between students at the start of their training compared with more advanced students. This paper gives an overview of student expectations for alignment with stated national human resources for health priorities for Timor-Leste.

    Increasingly popular mobile health (mHealth) programs have been proposed to promote better utilization of maternal, newborn and child health services. However, women who lack access to a mobile phone are often left out of both mHealth programs and research. In this study, we determine whether household mobile phone ownership is an independent predictor of utilization of maternal and newborn health services in Timor-Leste. The study included 581 women aged 15-49 years with a child under the age of two years from the districts of Manufahi and Ainaro in Timor-Leste. Participants were interviewed via a structured survey of knowledge, practices, and coverage of maternal and child health services, with additional questions related to ownership and utilization of mobile phones. Mobile phone ownership was the exposure variable, and the dependent variables included having at least four antenatal care visits, skilled birth attendance, health facility delivery, a postnatal checkup within 24 h, and a neonatal checkup within 24 h for their youngest child. Logistic regression models were applied to assess for associations. Sixty-seven percent of women reported having at least one mobile phone in the family. Women who had a mobile phone were significantly more likely to be of higher socioeconomic status and to utilize maternal and newborn health services. However, after adjusting socioeconomic factors, household mobile phone ownership was not independently associated with any of the dependent variables. Evaluations of the effects of mHealth programs on health in a population need to consider the likelihood of socioeconomic differentials indicated by mobile phone ownership.

    The five exons and the 5' and 3'-untranslated regions (5'-UTR and 3'-UTR) of the oGH gene were screened for mutations using PCR-single strand conformation polymorphism (PCR-SSCP) procedures in 523 Serra da Estrela ewes and were found to be highly polymorphic. The region extending across and between the GH2-N and GH2-Z copies was sequenced allowing the design of primers for the specific PCR amplification of each copy. These were cloned and sequenced in 20 animals representative of all SSCP patterns. The corresponding genotypes were established for each copy following nucleotide sequencing of SSCP alleles. Twenty-four polymorphic sites were found at the GH2-N (or GH1) and fourteen at the GH2-Z copies. Eight amino acid substitutions were predicted at the GH2-N and six at the GH2-Z copies. Milk yield adjusted to 150 lactation days was analysed for the genotype of each oGH gene copy taken separately or together (associated genotypes) by restricted maximum likelihood (REML) through a univariate best linear unbiased prediction (BLUP) animal model with repeated measures. Significant associations between genotypes and milk yield were observed. Within GH2-N genotypes there was a milk yield differential of 21.4+/-0.2 l/150 d between the most (N7) and the least (N5) productive ones. Within GH2-Z genotypes there was a differential of 21.6+/-0.2 l/150 d between the most (Z8) and the least (Z1) productive ones. The effect of associated GH2-N and GH2-Z genotypes revealed a differential of 39.6+/-0.3 l/150 d between the most (N1+Z7) and the least (N3+Z2) productive associated genotypes. The results show that GH2-N and GH2-Z genotypes significantly affect milk yield in Serra da Estrela ewes. Moreover, the apparent joint effect of GH2-N and GH2-Z genotype could improve milk yield in 25% as compared with the mean milk production of the analysed population.

    Full Text Available Peatlands are soil environments that store carbon and large amounts of water, due to their composition (90 % water, low hydraulic conductivity and a sponge-like behavior. It is estimated that peat bogs cover approximately 4.2 % of the Earth's surface and stock 28.4 % of the soil carbon of the planet. Approximately 612 000 ha of peatlands have been mapped in Brazil, but the peat bogs in the Serra do Espinhaço Meridional (SdEM were not included. The objective of this study was to map the peat bogs of the northern part of the SdEM and estimate the organic matter pools and water volume they stock. The peat bogs were pre-identified and mapped by GIS and remote sensing techniques, using ArcGIS 9.3, ENVI 4.5 and GPS Track Maker Pro software and the maps validated in the field. Six peat bogs were mapped in detail (1:20,000 and 1:5,000 by transects spaced 100 m and each transect were determined every 20 m, the UTM (Universal Transverse Mercator coordinates, depth and samples collected for characterization and determination of organic matter, according to the Brazilian System of Soil Classification. In the northern part of SdEM, 14,287.55 ha of peatlands were mapped, distributed over 1,180,109 ha, representing 1.2 % of the total area. These peatlands have an average volume of 170,021,845.00 m³ and stock 6,120,167 t (428.36 t ha-1 of organic matter and 142,138,262 m³ (9,948 m³ ha-1 of water. In the peat bogs of the Serra do Espinhaço Meridional, advanced stages of decomposing (sapric organic matter predominate, followed by the intermediate stage (hemic. The vertical growth rate of the peatlands ranged between 0.04 and 0.43 mm year-1, while the carbon accumulation rate varied between 6.59 and 37.66 g m-2 year-1. The peat bogs of the SdEM contain the headwaters of important water bodies in the basins of the Jequitinhonha and San Francisco Rivers and store large amounts of organic carbon and water, which is the reason why the protection and preservation

    Apesar da astronomia ser um dos temas indicados pelos Parâmetros Curriculares Nacionais, observa-se que poucas mudanças ocorreram desde a implementação do mesmo em sala de aula. A presente pesquisa diz respeito sobre como os tópicos de astronomia estão sendo abordados pelos professores no ensino médio. Optou-se por aplicar um questionário com os professores que ministram a disciplina de física. Os mesmos trabalham em escolas estaduais situadas nas cidades de Ribeirão Pires e Rio Grande da Serra, ambas subordinadas a Diretoria de Ensino de Mauá, no Estado de São Paulo. O questionário foi aplicado durante o 2° semestre de 2006. Até o momento os resultados são preliminares. Dos 82,0% dos professores que responderam ao questionário no município de Rio Grande da Serra, 66,7% não aplicaram nenhum tópico de astronomia, 77,8% não utilizaram qualquer tipo de programa computacional, 66,7% não utilizaram laboratório, que 77,8% nunca levaram os alunos a museus e ou planetários e que 66,7% não indicaram qualquer tipo de revista ou livro sobre astronomia aos seus alunos. No município de Ribeirão Pires, 53,3% dos professores responderam ao questionário, destes 75,0% não aplicaram nenhum tópico de astronomia, 93,8% não utilizaram qualquer tipo de programa computacional, 75,0% não utilizaram laboratório, 81,3% nunca levaram os alunos a museus e ou planetário e 56,3% não indicaram qualquer tipo de revista ou livro sobre astronomia ao seus alunos. Apesar da maioria dos professores reconhecerem que o conteúdo de astronomia influi na formação do jovem, os mesmos não incluem o tema em seus planejamentos escolares.

    The serra da Estrela (1,993 m asl) is the highest mountain range in mainland Portugal. Bounded by two main fault scarps, a granite massif occupies the central area forming a summit plateau between ci. 1,500 and 2,000 m. To the north and south, schists and greywackes dominate the landscape, also with granite presence. During the Last Glacial a plateau ice-field and five radiating valley glaciers occupied the highest parts of the mountain with an estimated equilibrium line altitude at 1,650 m asl. The plateau style of the glaciation and the Equilibrium Line Altitude just below the plateau edge made the Estrela very sensitive to climate fluctuations, having resulted in several terminal moraine complexes that reveal several glacial stages. The central plateau area shows widespread glacial erosion features and an almost complete stripping of the Cenozoic weathering mantle. The non-glaciated plateaus show a rich landscape dominated by granite weathering landforms. The remarkable glacial landscape of the serra da Estrela when considering its setting in SW Europe, together with other significant geoheritage such as periglacial, weathering and mass wasting phenomena, tectonic, petrological and hydrogeological features, are at the core of Estrela's application to become a UNESCO Global Geopark. But the framework of the application encompasses both the natural and the human landscape, involving nine municipalities in the wider Estrela range, whose population bears an Estrelean signature in its roots, traditions, culture and economy. The Estrela Aspiring Geopark builds on a high value geoheritage closely bonded with biodiversity and the local communities, and its strategy aims at conservation and promoting regional development in an interdisciplinary approach committed UNESCO's principles. This presentation is a brief overview of the Estrela geoheritage, with a focus on the strategy for the implementation and management of the Geopark, emphasising on the science-support plan

    The analysis of trace elements such as rare earths, Th, U, Ta, Hf, Ba, Rb and Ba, is a very important tool for petrogenetic studies. In order to study these processes in dykes of Enxame Serra do Mar (Coast of Sao Paulo and Rio de Janeiro), belonging to the Parana Magmatic Province (PMP), one of the most significant provinces of continental basalts in the world, were perform analyzes by neutron activation in these dikes. The technique, employed in Centro de Reator de Pesquisa of the Instituto de Pesquisas Energeticas e Nucleares, provided concentrations of trace elements with accuracy levels of 10% and 9%, which are suitable for petrogenetic studies. Due to the low concentrations of the elements analyzed, the experimental routine sample preparation processes covered very careful to avoid contamination. The samples investigated can be divided into four groups: basic rocks (SiO{sub 2} <55%) with Ti / Y> 500; basic rocks with Ti / Y <500; intermediate rocks (55% 63%). Dikes of intermediate and acid composition only occur at the Sao Sebastiao Island and adjacent coastal region. The concentrations of major and minor elements, as well as the abundance patterns of rare earths and other incompatible elements of these more differentiated rocks, show significant similarities with the type of the volcanic Chapeco, suggesting similar genesis, in other worlds, including also processes of crustal contamination.

In order to contribute to a better utilization of tire rubber residues generated in the retreading process, this paper was conducted with the aim of evaluating the absorption and compressive strength of concrete blocks for masonry, with residues and aggregates found in the western region of Santa Catarina State. Thus, concrete blocks were prepared with partial replacement of coarse aggregate for rubber residues in proportions of 15%, 25% and 35%, in mass, which were compared with blocks of a reference mix without residue. The test results confirmed a tendency to increase the absorption and reduction of the compressive strength of the blocks with the increase of the amount of residues tire rubber in the concrete mix. However, the mixture with 15% residue satisfies the minimum value of 3.0 MPa for the characteristic compressive strength and a 10% maximal absorption for hollow concrete blocks with structural function for use in masonry elements above the ground level. = O constante crescimento do número de veículos de cargas e passageiros em circulação acarreta aumento da quantidade de pneus com necessidade de recapagem ou que se tornam inservíveis.

    Full Text Available Fruit-feeding butterflies are used in ecological studies following standardized sampling protocols because they are easily collected using traps baited with food. This trait, and the fact that their populations respond rapidly to changes in habitat, make them good biological indicators. The goal of this study is to present a list of fruit-feeding butterfly species, including morphological and ecological characteristics of this group, for the Atlantic Forest of Serra do Tabuleiro State Park (Santa Catarina, to improve the knowledge about the butterflies from this region. Six field expeditions were carried out between November 2009 and August 2010. Twenty-five bait traps were used, which remained active for ten days and were checked every 48 h to replace the bait and collect individuals. Twenty species and 331 individuals were captured, which belonged to three subfamilies: Biblidinae, Charaxinae and Satyrinae. The study added eleven new species to the already existing list of the Atlantic Forest butterflies of Santa Catarina.

    Full Text Available This study aimed to evaluate the presence of enterotoxigenic S. aureus in the endogenous starter and in Artisan Minas cheeses from the Serra da Canastra. Sixteen samples of endogenous starters and cheese were collected during the rainy and dry seasons. The isolation and enumeration of S. aureus were performed using the PetrifilmTM-Rapid S. aureus Plate Count method. The presence of enterotoxin in the cheese samples was analyzed by the Optimal Sensitivity Plate (OSP method and the ELFA-VIDAS®-Staph enterotoxin-II assay. S. aureus strains were tested for their ability to produce enterotoxins using the Optimal Sensitivity Plate (OSP method and the polymerase chain reaction (PCR assay for the classical enterotoxin genes. The Optimal Sensitivity Plate (OSP method data showed that staphylococcal enterotoxin A (SEA was detected in 75% of the cheese samples, but no toxin was detected with the ELFA-VIDAS method. It was found that 12.5% of the isolated strains produced staphylococcal enterotoxin A (SEA and staphylococcal enterotoxin C (SEC. When using the the polymerase chain reaction (PCR assay, only one isolate was found to harbor an enterotoxin gene, contrary our expectations. However, discrepancies between the immunological and molecular assays are not uncommon. Despite the fact that most isolates did not produce classical enterotoxins, high S. aureus counts in the cheese samples causes concern since there is a risk of the presence of non-classical enterotoxins.

    Limeira city is located in the Sao Paulo State, in the second area of the State with the largest economic and demographic growth. It possesses expressive economy, with industries in several productive sections. As the Graminha and Aguas da Serra streams present its nascent ones in the urban zone of the Limeira city, they cross part of the rural zone and it unites draining in the Piracicaba River, it is possible that these basins suffer or have already suffered the impacts related to the environmental pollution caused by anthropogenic factors. Once the city have galvanization industries for the jewels, semi-jewels and bijoux production the descriptions and interpretations of the concentrations of heavy metals, in the water and in the sediments, are indicative to elucidate the influence anthropogenic and the loading of these compounds for Piracicaba River. For the metal determination Synchrotron Radiation Total Reflection X-Ray Fluorescence (SR-TXRF) was used. All measurements were performed using a white beam of synchrotron radiation for excitation and a Ge hyperpure detector. Detection limits for water samples was 0.04 -{mu}g.L{sup -1} and in sediment samples 0.03 {mu}g.g{sup -1} for Cu and Zn elements. In the water samples concentrations higher than permissive values established by CONAMA for Al, Fe, Zn, Cr, Ni, Cu and Pb were observed. For sediment samples values higher than reference value quality defined by CETESB was verified for Cr, Zn, Cu, Ni and Pb. (author)

    The lectin Eucheuma serra agglutinin (ESA) is known from previous studies to specifically bind to high-mannose type N-glycans and to induce apoptotic cancer cell death in vitro. In this study, Span 80 vesicles, with an average diameter between about 200 and 400 nm, containing immobilized ESA were prepared from the nonionic surfactant Span 80, also known as sorbitan monooleate. The vesicles were investigated in vitro and in vivo to evaluate the vesicles's potential applicability as novel drug delivery system. The results obtained are promising since the following was observed: (i) vesicular ESA had the same hemagglutinating activity as free ESA, demonstrating its biological activity when bound to the vesicles; (ii) vesicles containing immobilized ESA decreased the viability of Colo201 cancer cells in vitro while the growth of normal cells was not affected; (iii) the vesicles showed binding to Colo201 cells in vitro and caused inhibition of cancer cell growth in nude mice to which the vesicle-treated cells were added; (iv) the vesicles diminished tumor growth after intravenous administration to nude mice which contained an implanted Colo201 tumor; (v) the vesicles showed a tendency to accumulate at the site of the tumor 6h after i.v. administration to nude mice. Thus, all measurements carried out indicate that this type of Span 80 vesicle can be considered as promising alternatives to conventional phospholipid-based vesicles.

    Down-core changes in sedimentary facies, elemental geochemistry, pollen, spore, δ13C, δ15N and radiocarbon records from a filled lake, named R4, of the Serra Sul dos Carajás were used to study the relationship between the paleomorphological and paleoecological processes and their significance for Holocene paleoclimatology of the southeast Amazonia. The sediment deposition of the R4 lake started around 9500 cal yr BP. Increase of detrital components from 9500 to 7000 cal yr BP suggests high weathering of surrounding catchment rocks and soils, and deposition into the lake basin under mudflows. At that time, montane savanna and forest formation were already established suggesting predominance of wet climate. However, from 7000 to 3000 cal yr BP, a decline of detrital input occurred. Also, forest formation and pteridophytes were declined, while palms and macrophytes were remained relatively stable, indicating that water levels of the lake is likely dropped allowing the development of plants adapted to subaerial condition under drier climate conditions. After 3000 cal yr BP, eutrophication and low accommodation space lead to high lake productivity and the final stage of the lake filling respectively, and forest formation may has acquired its current structure, which suggests return of wetter climate conditions.

    Full Text Available This study aimed to provide support for the implementation of rafting in the Parque Estadual Serra do Mar – Núcleo Santa Virgínia (PESM-NSV State Park based upon the profile and the level of satisfaction of the practitioners of rafting. Data was collected via questionnaires, with closed and open questions to assess the socioeconomic profile of the practitioners, information regarding commuter trips, motivations, preferences, level of satisfaction with respect to the activities engaged in , as well as the practitioners’ perceptions of the experience and minimum impact of the visits. After the data was tabulated, an Analysis of Correspondence technique was used to verify the relationship between the “satisfaction” and “age” variables using MINITAB™ statistical software. Out of 47 people interviewed, the majority were males (66%, of which 55.5% were between 19 and 30 years old and 49% of the participants had college degree. In general, participants were satisfied with the service, but made it clear that some aspects of the rafting business management could be improved upon, such as a reduction of the admission fee, use of availability announcements and improvement of the infrastructure of the landing area of the cruising. It is concluded that the rafting participants are from an elite class of society with a high level of education and a demand for a high quality of service.

    Full Text Available Areas that comprise "damping zones" are important in minimizing the effects of impacts on the environment as they can affect the conservation unit, and in helping to maintain its natural resources. However, they are not protected and many are handled improperly, compromising the sustainability of the conservation units they should protect. The aim of this study was to evaluate the effect of human disturbance in the damping zone on the soil quality inside the Biological Reserve Serra dos Toledos, Itajubá-MG. For this, there were selected three areas under different activities in the damping zone (pasture, agriculture, and native forest and three areas sided to those, within the Reserve. They were characterized according to various physical, chemical, microbiological, and visual soil quality procedures. Areas that had the worst physical, visual, and microbiological conditions were those located in the damping zone under agriculture and pasture. The microbiological attributes were sensitive to the different areas, due to the direct relation between negative impact of agriculture practiced in the damping zone and the soil quality within the Biological Reserve studied.

    Full Text Available This work was carried out at the Núcleo Santa Virginia (State Park of Serra do Mar, São Paulo, Brazil (45º 30' W and 23º 17' S and has the goals of evaluating the response of the palm community in two landslide areas that occurred in the summer of 1996 due to an atmospheric event (Convergence Zone of South Atlantic. One of them is located in preserved forest area and the other in a secondary vegetation area nearby. In order to evaluate the palm community distribution, 100m2 circular plots were allocated in the edges of the scars of the landslides and in the interior of the adjacent vegetation for three altitudes (bottom, middle and top. The palms were classified in three ontogenetic stages (seedlings, juveniles and adults which represent five species in preserved area (canopy species: Attalea dubia and Euterpe edulis, understorey species: Geonoma gamiova, G. pohliana and G. schottiana and four species in secondary area (the same species, except G. pohliana. The disturbance caused perturbation in the palm community. The juveniles of species E. edulis and G. schottiana were stimulated by the increase in luminosity provoked by landslides while G. gamiova decreased drastically in these conditions for all developmental stages. The regeneration pattern observed indicates that species from different forest strata can respond in different ways to this type of environmental disturbance.

    Full Text Available Estudos de estrutura de tamanho e de estágios ontogênicos são importantes para se compreender quais fatores influenciam os processos populacionais, a regeneração e a resposta a perturbações de uma população. Este estudo analisou a estrutura de uma população de Kielmeyera rugosa Choisy (Clusiaceae no hábitat de Areias Brancas do Parque Nacional Serra de Itabaiana, Estado de Sergipe. Amostraram-se aleatoriamente 30 parcelas de 20 x 25 m, nas quais se determinou a abundância de indivíduos jovens e adultos, a circunferência do tronco, a altura da copa e o número de caules por planta. A distribuição espacial de jovens e adultos na população é agregada, causada por sua predisposição em formar grupos em locais onde há maiordisponibilidade de recursos e condições favoráveis. Outro fator que contribui com a agregação é a dispersão anemocórica da espécie. A população estudada apresentou o maior número de indivíduos nas categorias menores de altura e de DAS, indicando que a população está em crescimento ou em processo de autorregeneração. Há maior número de indivíduos de 2-3 m de altura, o que se deve ao fogo ou corte, eventos que não foram capazes de interromper o processo de recrutamento ou reprodução da espécie na área, pois não ocorreram lacunas nas classes de diâmetro de caule.Studies on structure, size and ontogenic stages are important to understand which factors influence population processes, regeneration and response to disturbances of a population. This study examined thestructure of a population of Kielmeyera rugosa Choisy (Clusiaceae in white sands habitat of Serra de Itabaiana, Sergipe State. Thirty 20 x 25 m plots were selected randomly selected, and their abundance of young and adult plants was recorded, as well as trunk circumference, crown height and number of stems per plant.

    Full Text Available A análise de bacias de drenagem, combinada com dados de sensoriamento remoto e cartográficos, fornece informações significantes para o reconhecimento de lineamentos morfoestruturais e para a detecção de feições tectônicas com expressão na paisagem atual. Este procedimento foi aplicado no estudo de três bacias de drenagem do leste da Ilha do Marajó, correspondentes aos rios Arari, Camará e Paracauari. Todas estas bacias mostram evidências de anomalias morfoestruturais, incluindo-se principalmente: mudanças rápidas no padrão de drenagem dentro de uma mesma bacia, variando de treliça, retangular, multibacinal a subparalelo; canais retilíneos comumente conectados em ângulos retos; canais fortemente sinuosos que se tornam retilíneos; meandros localizados; e bacias altamente assimétricas. Anomalias de drenagem, consistindo em frequentes desvios de direção formando ângulos retos e meandros isolados e comprimidos, são também reconhecidas na paleodrenagem preservada neste setor da ilha. Com base na densidade dos lineamentos estruturais, pode-se reconhecer dois compartimentos morfoestruturais. O compartimento I é localizado na porção centro-leste da área de estudo, onde ocorre densidade de lineamento alta com duas direções preferenciais para NW-SE e NE-SW. O compartimento II, correspondente ao restante da área, apresenta densidade de lineamentos variando entre muito baixa a média e com orientação principal para NE-SW. As características morfoestruturais dos sistemas de drenagem atual e pretérita permitem sugerir área com forte controle tectônico. A deformação tectônica pode refletir reativação de falhas de direções principais NW-SE e NE-SW, melhor registradas no compartimento I.

    Women in conflict-affected countries are at risk of mental disorders such as posttraumatic stress disorder and depression. No studies have investigated the association between experiences of abuse and injustice and explosive anger amongst women in these settings, and the impact of anger on women's health, family relationships and ability to participate in development. A mixed methods study including an epidemiological survey (n = 1513, 92.6% response) and qualitative interviews (n = 77) was conducted in Timor-Leste. The indices measured included Intermittent Explosive Disorder, posttraumatic stress disorder; severe distress; days out of role (the number of days that the person was unable to undertake normal activities); gender-specific trauma; conflict/violence; poverty; and preoccupations with injustice. Women with Intermittent Explosive Disorder (n = 184, 12.2%) were more disabled than those without the disorder (for >5 days out of role, 40.8% versus 31.5%, X(2) (2) = 12.93 p = 0.0016). Multivariable associations with Intermittent Explosive Disorder, controlling for the presence of PTSD, psychological distress and other predictors in the model, included the sense of being sick (OR 1.73; 95% CI 1.08-2.77); victimization as a result of helping the resistance movement (OR 2.33, 95% CI 1.48-3.68); war-related trauma specific to being a woman (OR 1.95, 95%, CI 1.09-3.50); ongoing family violence and community conflict (OR 1.88, 95% CI 1.27-2.77); extreme poverty (OR 1.23, 95%, CI 1.08-1.39); and distressing preoccupations with injustice (relating to 2/3 historical periods, OR 2.10, 95% CI 1.35-3.28). In the qualitative study, women elaborated on the determinants of anger and its impact on their health, family and community functioning, child-rearing, and capacity to engage in development. Women reflected on the strategies that might help them overcome their anger. Intermittent Explosive Disorder is prevalent and disabling amongst women in conflict-affected Timor-Leste

    Full Text Available This study was set out with the objective of analyzing successional process in areas which are deforested and dominated by Pteridium aquilinum in the Serra da Mantiqueira mountain range, by researching the natural regeneration of shrub and tree species and evaluating both disturbance history and the edaphic conditions on the natural regeneration community. This research investigated two abandoned pasture areas in Bocaina de Minas county exposed to natural regeneration intervals ranging from six years (area named 6A to twenty years (area named 20A. The inventory occurred from sixty plots of 10 m², where all samples surveyed were between 0.15 m and 3 m high. All samples were identified and both the diameter in ground level and total height of the specimens were measured. The survey totaled 1,159 samples and 53 species. Melastomataceae was registered with the highest species richness and the highest specimen abundance. The two sampled areas showed species composition differences, with Jaccard similarity coefficient equal to 3.7%. The canonical correspondence analysis showed the correlations between natural regeneration stratum and non-labile phosphorus and clay in the 6A area. On the other hand, the 20A area showed correlations between plant regeneration and the K, P, Ca²+, Al³+ levels, with higher pH levels, and with the sum of exchangeable bases. In addition, the vegetation surveyed in area 20A was correlated with higher Pteridium population density. The results showed that the dominance of Pteridium aquilinum leads to successional process under inhibition, in which the ferns act negatively on the richness and abundance of shrub populations. It was also confirmed the Pteridium's affinity to steep areas, mainly in higher altitudes, where the soil is acid, as well as its preference to disturbed areas. Moreover, we highlight the fragilities of the mountain environments and the importance of preserving natural vegetation, as well as the bracken

    Full Text Available The main goals of this study were: 1 to evaluate the structure, diversity, and functional trophic group composition of benthic macroinvertebrate communities; 2 to characterize water quality in the headwaters of the Doce river watershed, based on physical, chemical, and biological parameters (benthic macroinvertebrates, fecal coliforms, heterotrophic bacteria, and yeasts; and 3 to contribute to the knowledge of the structure and function of longitudinal gradients in lotic ecosystems in Brazil. A total of 60 benthic macroinvertebrate taxa were identified, the dominant group being the aquatic insects, with 50 families distributed in 8 orders. The dry period presented higher values of taxonomic richness and total density of benthic macroinvertebrates. A decreasing gradient was observed in these variable values from the 3rd order stretch down to the 6th order stretch. The highest Shannon-Wiener diversity values were found in the rainy period in the 3rd order stretches, which presented well-developed riparian forest. Besides the 3rd order stretches, the Pielou evenness index values were also high in the 6th order stretch. The collectors, together with the scrapers, predominated in the benthic macroinvertebrate communities in all river stretches, except in the 2nd, 4th, and 5th order stretches in the rainy period, where communities were dominated by filterers. The shredders and predators presented low densities for all river stretches. All microbiological variables presented low levels. Due to the high counts of heterotrophic bacteria and coliforms, the studied river stretches presented inadequate potability but adequate balneability levels. The results suggest that the structure, diversity, and composition of the benthic macroinvertebrate communities are influenced by the trophic resource availability, seasonality, and sediment heterogeneity. The microbiological results of this study allow inferring that the waters from Serra do Cipó have excellent

As coletas ocorreram em duas expedições, uma na estação seca (agosto e setembro de 2003 e outra na chuvosa (março e abril de 2004. Cada expedição contou com a participação de três coletores. O esforço de amostragem foi de 240 amostras, sendo 96 através de guarda-chuva entomológico e rede de varredura, 96 através de coleta manual noturna e 48 por triagem manual e extratores de Winkler. Foi comparada a diversidade de aranhas de quatro tipos de vegetação, Floresta Ombrófila Aberta, mata de galeria, áreas de Cerrado (Savana Arbórea e de Campina. As coletas resultaram em um total de 4.990 indivíduos, dos quais 2.750 adultos. Foram identificadas 427 morfoespécies em 37 famílias, sendo as mais abundantes Theridiidae, Salticidae e Araneidae e as mais ricas em espécies Araneidae, Salticidae e Theridiidae. As espécies representadas por apenas um indivíduo somaram 40% do total e apenas duas ultrapassaram cem indivíduos. A curva de riqueza específica estimada (ACE atingiu 614 espécies. A maior diversidade alfa (índice de Shannon-Wiener foi encontrada em Floresta Ombrófila, seguida pela mata de galeria, Campina e Cerrado. Tais diferenças entre as vegetações podem ser explicadas devido a variações na complexidade da vegetação e na disponibilidade de microhábitats em cada fitofisionomia.

    Full Text Available The Cerrado is the second largest biome in Brazil after the Amazon and is the savanna with the highest biodiversity in the world. Serra Tombador Natural Reserve (STNR is the largest private reserve located in Goiás State, and the fourth largest in the Cerrado biome. The present study aimed to map the burnt areas and to describe the spatial patterns of fire recurrence and its interactions with the classes of land-cover that occurred in STNR and its surroundings in the period between 2001 and 2010. Several Landsat TM images acquired around the months of July, August and September, coinciding with the region’s dry season when fire events intensify, were employed to monitor burnt areas. Fire scars were mapped using the supervised Mahalanobis-distance classifier and further refined using expert visual interpretation. Burnt area patterns were described by spatial landscape metrics. The effects of fire on landscape structure were obtained by comparing results among different land-cover classes, and results summarized in terms of fire history and frequencies. During the years covered by the study, 69% of the areas analyzed had fire events. The year with the largest burnt area was 2004, followed by 2001, 2007 and 2010. Thus, the largest fire events occurred in a 3-year cycle, which is compatible with other areas of the Brazilian savanna. The regions with higher annual probabilities of fire recurrence occur in the buffer zone around the park. The year 2004 also had the highest number of burnt area patches (831. In contrast, the burnt area in 2007 showed the most extensive fires with low number of patches (82. The physiognomies that suffered most fires were the native savanna formations. The study also identified areas where fires are frequently recurrent, highlighting priority areas requiring special attention. Thus, the methodology adopted in this study assists in monitoring and recovery of areas affected by fire over time.

Geo-processing techniques were used for producing a preliminary risk map for altimetry (a, land slope (e, slope orientation (d, land-use/cover (u and influence of roads and buildings (i. After, the risk maps were overlaid to produce a structural fire index (SFI-based risk map for the Park. The SFI was calculated by using the formula SFI = 0,35i + 0,30u + 0,15d + 0,10a + 0,10e. The risks classes were classified as low (0.0-0.9, moderate (1.0-1.9, high (2.0-2.9, very high (3.0-3.9 and extreme (4.0-5.0. All data were processed with 2.5 m base spatial resolution by using the ArcView GIS. According to the SFI calculated, the SSMP area can be divided into the following fire risk zones: Low (0.93%, Moderate (61.77%, High (31.32%, Very High (4.79% and Extreme (1.19%. The main risk factor is due to the influence of roads and buildings and most fires start due to anthropogenic causes. The low and moderate risk classes comprehend most of the rainforest area. Clearings and grasslands fit mainly the High risk class. The most vulnerable area of SSDMP was the Northern area bordering pasture, crops and eucalypt fields. The SFI map can be a valuable tool for elaborating a fire prevention plan in a small conservation unit when few climate and fire occurrence data are available.

    Full Text Available A Reserva Natural Serra do Tombador (RNST protege um grande remanescente natural nesse bioma. Nós analisamos a dinâmica da paisagem no seu entorno, monitorando a perda de habitat entre 2001 e 2008. A região de análise foi dividida em quarto quadrantes e em 64 células. Foram desenhados quatro buffers no entorno da Reserve, definidos a partir de 5, 10, 15 e 20 km dos seus limites. Métricas da paisagem foram geradas para os polígonos de desmatamento, que se tornaram mais numerosos em 2008, mostrando um aumento na fragmentação da paisagem. Esses resultados sugerem uma rápida conversão da paisagem analisada, ameaçando a biodiversidade da RNST pela fragmentação, isolamento e diminuição da conectividade da Reserva com outras áreas protegidas. Porém, a área alterada não apresentou mudança significativa, sugerindo uma oportunidade para a criação de novas unidades de conservação para proteção da biodiversidade. As principais ameaças para essa paisagem são o estabelecimento de estradas pavimentadas e reservatórios de pequenas centrais hidrelétricas, ambos planejados para a região. Para alcançar os objetivos da RNST de manter a biodiversidade regional, sugerimos a criação de novas áreas protegidas na região, principalmente nos quadrantes Nordeste e Noroeste, e atenção à conectividade entre a RNST e o PNCV.

    Full Text Available Soil information is needed for managing the agricultural environment. The aim of this study was to apply artificial neural networks (ANNs for the prediction of soil classes using orbital remote sensing products, terrain attributes derived from a digital elevation model and local geology information as data sources. This approach to digital soil mapping was evaluated in an area with a high degree of lithologic diversity in the Serra do Mar. The neural network simulator used in this study was JavaNNS and the backpropagation learning algorithm. For soil class prediction, different combinations of the selected discriminant variables were tested: elevation, declivity, aspect, curvature, curvature plan, curvature profile, topographic index, solar radiation, LS topographic factor, local geology information, and clay mineral indices, iron oxides and the normalized difference vegetation index (NDVI derived from an image of a Landsat-7 Enhanced Thematic Mapper Plus (ETM+ sensor. With the tested sets, best results were obtained when all discriminant variables were associated with geological information (overall accuracy 93.2 - 95.6 %, Kappa index 0.924 - 0.951, for set 13. Excluding the variable profile curvature (set 12, overall accuracy ranged from 93.9 to 95.4 % and the Kappa index from 0.932 to 0.948. The maps based on the neural network classifier were consistent and similar to conventional soil maps drawn for the study area, although with more spatial details. The results show the potential of ANNs for soil class prediction in mountainous areas with lithological diversity.

    The Rio Fortuna Gneiss crops out in the Serra Santa Barbara, near the Fortuna military headquarters, on the Brazil-Bolivia border. These orthogneisses are located in a portion of the Paragua terrain affected by the Sunsas Orogeny (1.0-0.9 Ga.). They are classified as monzo to granodiorite orthogneisses and underwent at least three episodes of deformation. The U-Pb zircon age of 1,711 ± 13 Ma obtained by laser ablation MC-ICP-MS is interpreted as the crystallization age of this orthogneiss. Geochemically, these rocks form a sequence comprising acidic subalkaline magmatism, calc-alkalic-type high-K, and metaluminous to peraluminous. (author)

Em uma estrutura de concreto que compõe uma barragem Vários instrumentos devem ser instalados de tal maneira que permitam leituras que avalie se a estrutura está em boas condições ou não, normalmente cada instrumento está destinado a coletar dados sobre características individuais da estrutura, possibilitando o diagnóstico de anomalias. O objetivo desse artigo é utilizar a instrumentação instalada em um bloco da barragem de Itaipu, para determinar modos de falhas possíveis de serem monitorados sem uma avaliação individual de cada instrumento. O método baseia-se no trabalho apresentado em XXX SNGB – Seminário Nacional de Grandes Barragens realizado em Foz do Iguaçu, que com o auxilio da análise fatorial, foi desenvolvido um método para determinação dos modos da falha possíveis de serem monitorados e de suas regiões críticas. Esse método será agora aplicado em um bloco chave de Itaipu, que é altamente instrumentado. Pretende-se, com essa aplicação obter resultados que comprove a eficiência desse método.

    Full Text Available Abstract Background In 2003, Timor-Leste successfully obtained its first Global Fund grant for a three-year programme for malaria control. The grant aimed to reduce malaria-related morbidity and mortality by 30 % by the end of the implementation. Methods A mixed-methods approach was used to assess the impact of the grant implementation. Fifty-eight in-depth interviews, eight group interviews, 16 focus group discussions, and on-site observations were used. Morbidity data reported to the Ministry of Health were also examined to assess trends. Results The National Malaria Programme with funding support from the Global Fund grant and other development partners contributed considerably to strengthening malaria control and the general health system. It also brought direct and indirect benefits to pregnant women and to the community at large. However, it failed to achieve the stated objective of reducing malaria morbidity and mortality by 30 %. The implementation was hampered by inadequate human resources, the rigidity of Global Fund rules, weak project management and coordination, and inadequate support from external stakeholders. Conclusion Despite limitations, the grant was implemented until the agreed closing date. Considerable contributions to malaria control, health system, and the community have been made and the malaria programme was sustained.

    Full Text Available O presente estudo investiga o impacto redistributivo dos processos de Orçamento Participativo sobre os gastos sociais nas cidades de Vitória e Serra/ES, no intuito de verificar em que medida as regiões tradicionalmente desfavorecidas são privilegiadas na distribuição de recursos. A relação entre democracia e justiça distributiva tende a ser fortalecida mediante o aumento de uma complexidade metodológica mediada por critérios objetivos e transparentes definidos segundo um complexo processo de conflito e negociação com base na reconfiguração das relações entre Estado e sociedade. A efetivação do OP enquanto política redistributiva é fruto de processos sociais resultantes do embate entre práticas sociais que, por sua vez, se consubstanciam em regras e normas coletivamente construídas e não da simples aplicação de um “modelo” supostamente eficiente.

    Eucheuma serra agglutinin (ESA) derived from a marine red alga, Eucheuma serra, is a lectin that specifically binds to mannose-rich carbohydrate chains. ESA is a monomeric molecule, with a molecular weight of29,000. ESA induced cell death against several cancer cell lines, such as colon cancer Colo201 cells and cervix cancer HeLa cells. DNA ladder detection and the induction of caspase-3 activity suggested that the cell death induced by ESA against cancer cells was apoptosis. ESA bound to the cell surface of Colo201 cells in the sugar chain dependent manner. This means that the binding of ESA to the cell surface is specific for mannose-rich sugar chains recognized by ESA. The binding of ESA to the cell surface of Colo201 cells was slightly suppressed by the high concentrations of serum because of the competition with serum components possessing the mannose-rich sugar chain motifs. On the other hand, a lipid vesicle is a very useful microcapsule constructed by multilamellar structure,and adopted as drug or gene carrier. ESA was immobilized on the surface of the lipid vesicles to apply the lipid vesicles to cancer specific drug delivery system. ESA-immobilized lipid vesicles were effectively bound to cancer cell lines compared with plane vesicles.

    Activities of gamma-ray emitting members of the uranium ({sup 238}U) and thorium ({sup 232}Th) series were measured in a quaternary limestone deposit that outcrops in the southeastern Pantanal Matogrossense Basin and in quaternary tufas deposited at the drainage of the Serra da Bodoquena. It is a first step in a study of the mobilization of uranium and thorium series and its relation to surface hydrology, in a region where carbonate deposits are being continuously dissolved and reprecipitated. The obtained results show that all these deposits are characterized by very low concentrations of uranium and thorium. The {sup 238}U/{sup 226}Ra and {sup 228}Th/{sup 228}Ra activity ratios are significantly different than 1.0, indicating that both series are in radioactive disequilibrium. Although the Serra da Bodoquena deposits seem to be very recent, their very fine granulation and high porosity suggest that they behave as open systems for geochemical exchanges of uranium and thorium series members. The Pantanal do Miranda limestone has a radiocarbon age of 3900 yr BP. Since the thorium series is in disequilibrium it is also concluded that this deposit behaves as an open system for geochemical exchanges.

    In the New World, the leishmaniases are primarily transmitted to humans through the bites of Leishmania-infected Lutzomyia (Diptera: Psychodidae) phlebotomine sand flies. Any or both of two basic clinical forms of these diseases are endemic to several cities in Brazil--the American cutaneous leishmaniasis (ACL) and the American visceral leishmaniasis (AVL). The present study was conducted in the urban area of a small-sized Brazilian municipality (Jaboticatubas), in which three cases of AVL and nine of ACL have been reported in the last five years. Jaboticatubas is an important tourism hub, as it includes a major part of the Serra do Cipó National Park. Currently, no local data is available on the entomological fauna or circulating Leishmania. During the one-year period of this study, we captured 3,104 phlebotomine sand flies belonging to sixteen Lutzomyia species. In addition to identifying incriminated or suspected vectors of ACL with DNA of the etiological agent of AVL and vice versa, we also detected Leishmania DNA in unexpected Lutzomyia species. The expressive presence of vectors and natural Leishmania infection indicates favorable conditions for the spreading of leishmaniases in the vicinity of the Serra do Cipó National Park.

    Full Text Available Biodiversity corridors comprise a mosaic of land uses connecting fragments of natural forest across a landscape. Two such corridors have been established along the eastern coast of Brazil: the Serra do Mar and the Central da Mata Atlântica corridors, along which most of the coastal plains are restinga areas. In this study, we analyze the present status of the endemic and endangered terrestrial vertebrates of both corridors. We sampled 10 restingas in both corridors, recording species of amphibians, reptiles, birds, and mammals. Some restingas harbor a relatively large number of endemic species, and two main regions of endemism can be identified along the restingas of both corridors: the coastal restingas from northern Espírito Santo State to southern Bahia State (between Linhares, ES, and Trancoso, BA, and the coastal region between the restingas of Maricá and Jurubatiba, Rio de Janeiro State. Six species of terrestrial vertebrates considered threatened with extinction are found in the restingas of Serra do Mar and Central da Mata Atlântica biodiversity corridors (Liolaemus lutzae, Formicivora littoralis, Mimus gilvus, Schistochlamys melanopis, and Trinomys eliasi. The region located between the restinga of Maricá and that of Jurubatiba is of special relevance for the conservation of vertebrate species of the restingas of the corridors because a considerable number of threatened species of terrestrial vertebrates are found there. We strongly recommend efforts to develop checklists of threatened faunas for the States of Espírito Santo and Bahia.

    Full Text Available We studied the species composition of the snake community of Serra do Mendanha, in Rio de Janeiro state, Southeastern Brazil, with an effort of 800 hours/man in different habitats, including undisturbed forest, secondary forest, areas under regeneration, and banana plantation. We sampled snakes monthly in the area using a combination of methods including intensive visual searching and pitfall traps with drift-fences. We found a total of 191 individuals of 27 snake species, belonging to four families: Boidae, Colubridae, Elapidae and Viperidae. In terms of species richness, the most speciose snake family in the area was Colubridae (85.2%; n = 23, followed by Viperidae (7.4%; n = 2, Boidae (3.7%; n = 1 and Elapidae (3.7%; n = 1 (Table 1.

    Analogue experiments were carried out to get insights into the processes governing positive inversion during the foreland propagating thrust tectonics in the southern Serra do Espinhaço, a Brasiliano/Panafrican foldthrust belt in southeast Brazil. In particular, model listric half-grabens were inverted by applying contractional displacement to the footwall blocks. We investigated two different inversion conditions in listric half-grabens: (i) extensional and contractional detachments at the same level and (ii) at different positions. The models revealed that the development of a forward-breaking thrust system occurs in the basin synrift deposits, by contractional translation of the extensional footwall block when the extensional and contractional master faults do not coincide. Our experiments show the tectonic imbrication between basement and synrift sequences which characterizes the southern Serra do Espinhaço, and support the location in the eastern mountain range domain of the Espinhaço rift master fault system, which is not exposed at the surface.

    Studies of magnetic properties of shocked basalt are underway for two impact craters in the 132 Ma Serra Geral basalt of southern Brazil: the Vista Alegre crater (25.95°S, 41.69°W) in the state of Paraná, with a diameter of 12.4 km, and the Vargeão crater (26.81°S, 52.17°W) in Santa Catarina, of 9.5 km. Shatter cones and quartz planar deformation features (pdfs) have been found at both structures. Uplifted crater rims and external ejecta deposits have been removed by erosion at both craters. The interior of the Vista Alegre crater contains ejecta fallback deposits, typically reworked and weathered, and basalts of the crater floor are poorly exposed. In contrast, shocked basalts are exposed across the interior of the Vargeão structure, ejecta fallback deposits have been removed by erosion, and a central domal uplift of quartzose strata from beneath the basalt is found. Discounting the possibility of differential erosion rates, these differences might suggest that the Vargeão is the older of the two structures. Laboratory experiments elsewhere have suggested that major axes of the ellipse of anisotropic susceptibility (K1 major; K3 minor) could be aligned with the direction of propagation of the shockwave accompanying impact processes. Insufficient exposures exist at Vista Alegre to test this hypothesis. Oriented samples along a NNW-trending diametral profile across the better exposed Vargeão structure did not show a radial alignment of either K1 or K3 relative to the centre of that structure. In general, the mean susceptibility at Vargeão is lower towards the center; the degree of anisotropy is low (Pj<1.01), and the highest degree of anisotropy is in basalts adjacent to the central uplift. The shape factor (T) varies considerably (-0.5 (prolate) to +0.7 (oblate)); most magnetofabrics are oblate. Only 3 of 16 sites are prolate, and those are near the crater margin. K3 (minimum) axes are mainly steep, with a mean direction steep and slightly north of the

    Full Text Available No Centro Nacional de Pesquisa de Trigo (CNPT - Embrapa Trigo, em 1999, genótipos de trigo integrantes do bloco de cruzamento foram avaliados quanto à altura de planta, à duração do ciclo até o espigamento, ao comprimento do pedúnculo e ao número de grãos por espiga. Relacionando essas características, foram estudados 122 genótipos em duas épocas de semeadura, que consistiram os blocos. Foram medidos dez pedúnculos do afilho principal, de cada genótipo, e contou-se o número total de grãos de cada espiga. Para a apresentação dos resultados, foram considerados os valores médios dessas avaliações. Para a análise estatística, considerou-se o experimento como blocos casualizados. Dos resultados obtidos, concluiu-se que os genótipos de trigo BR 18, BR 42 e Sonora 64 destacam-se por porte baixo e ciclo precoce, enquanto Florida 301 e "Trigo de chapéu" destacam-se por porte alto e ciclo longo até o espigamento. A altura de planta mostra elevada correlação com comprimento do pedúnculo e duração do ciclo até o espigamento, e esta, com o comprimento de pedúnculo. Os genótipos de trigo CNT 10 e PF 92130 são indicados com finalidades artesanais por suas características de pedúnculo longo e número de grãos por espiga acima da média.

Assim, este trabalho tem por objetivo utilizar o planejamento experimental aplicado ao estudo de misturas para avaliar a potencialidade do uso conjunto dos resíduos do beneficiamento do caulim e da serragem do granito para a produção de blocos e revestimentos cerâmicos. Utilizando o planejamento experimental foram formuladas determinadas composições com as matérias-primas. As matérias-primas foram misturadas em determinadas proporções e confeccionados corpos de prova por extrusão e por prensagem uniaxial. Os corpos de prova foram queimados e, em seguida, determinou-se sua absorção de água e módulo de ruptura à flexão. Foram ajustados modelos matemáticos de regressão relacionando a absorção de água e o módulo de ruptura com as proporções das matérias-primas. Os resultados mostraram que o procedimento de planejamento experimental utilizado permite maximizar a quantidade de resíduo incorporado às formulações para blocos e revestimentos cerâmicos, sendo possível a incorporação de teores de resíduos de até 50% em formulações para a produção de blocos cerâmicos e de ate 40% em composições para a produção de revestimentos cerâmicos.The use of experimental design to the study of mixtures has found a wide range of applications, even in laboratory scale or in industrial development works.

Deste modo, tem-se por objeto de estudo desta pesquisa o Bloco Inicial de Alfabetização (BIA que, por objetivo geral, pretende analisar o delineamento da política de alfabetização no município de Dourados/MS a partir da apreciação do BIA, e especificamente identificar as concepções e modalidades de ciclos presentes em documentos e na literatura, caracterizar e analisar no município referido, a proposta de organização do processo de alfabetização na modalidade do BIA e analisar três dos eixos estruturais da proposta pedagógica do BIA, sendo estes o currículo, a alfabetização e o letramento e a avaliação entendendo estes como possíveis caminhos para a concretização dos objetivos propostos. Para isso utilizou-se a pesquisa bibliográfica e análise documental, bem como a técnica de entrevista para levantamento de dados empíricos, configurando assim esta pesquisa a partir de uma abordagem qualitativa. Identificou-se que, como outras modalidades de ciclos investigadas, o BIA apresenta as mesmas dificuldades quanto ao seu processo de delineamento e implantação, fazendo-se necessário o trabalho paralelo de formação junto aos coordenadores e professores para melhor fundamentação da proposta do bloco e revisão das práticas avaliativas e alfabetizadoras, bem como da elaboração do currículo. Constatou-se que a qualidade do processo de alfabetização e letramento ainda continua atrelada às questões da reprovação e do fracasso escolar. Conclui-se que é imprescindível para a concretização das profundas transformações requeridas nas concepções, posturas e práticas que vão ao sentido contrário da lógica da

    Full Text Available O lodo gerado nas estações de tratamento de esgoto tem se tornado um problema crescente sendo considerado como resíduo. Este trabalho estudou a viabilidade da incorporação do lodo de estação de tratamento de esgoto (ETE em massa cerâmica para produção de blocos. Para isso, amostras de lodo foram coletadas na ETE Verde da SANEPAR no Município de Ponta Grossa, PR e de argila da Cerâmica S. Gerônimo no município de Prudentópolis, PR. O lodo na ETE Verde foi submetido a um processo de higienização, o qual reduz significativamente a concentração de patógenos no resíduo. O processo utilizado foi a caleação, que promove a estabilização, desinfecção química e térmica através da adição e mistura da cal ao lodo numa porcentagem de 30% a 50% da massa seca de lodo. Para a caracterização do lodo e da argila foram realizadas análises de difração de raios X, análise térmica diferencial e termogravimétrica, fluorescência de raios X e distribuição granulométrica. Foram estudadas composições com adições de 5 a 50% em massa do lodo na massa cerâmica. Após a mistura do lodo com as argilas, as amostras foram conformadas por prensagem uniaxial e sinterizadas a 900 ºC, 1000 ºC e 1100 ºC. As amostras sinterizadas foram caracterizadas por medidas de absorção de água, porosidade aparente, resistência mecânica, difração de raios X e microscopia eletrônica de varredura. Os resultados mostraram que a adição do lodo até 25% da massa da argila atende a todos os parâmetros preconizados pelas normas vigentes para fabricação dos blocos cerâmicos.

    Full Text Available One event of three consecutive days and another of four consecutive days of Stratus clouds were registered at the Maceio airport on the northeast coast of Brazil. This is a very rare phenomenon for equatorial regions and it was analyzed using the high resolution (10km ETA model, NCEP reanalysis, satellite data and conventional data supplied by the Hydrometeorological Directory DHM-SERHI/AL and by the Department of Flight Protection of the Zumbi dos Palmares airport. Wave disturbance in the trade winds and weak ascendant movements at low levels (1000 and 925hPa were identified. At the same time, anticyclonic curvature at high levels formed descendant movements and subsidence inversion. These vertical movements combined with a stable layer between 850 and 700hPa created a very humid layer at the low levels. The precipitation forecasted by the ETA model with 24h antecedence presented a satisfactory result for an average quantity of precipitation. Nevertheless, the spatial distributions of forecasted and observed precipitation were different. Precipitation during all days was not forecasted for the coastal region, and for the west region the forecasted precipitation was more intense than the observed ones.Foram registrados dois eventos de três e quatro dias consecutivos de nuvens Stratus no aeroporto de Maceió na costa leste do Nordeste Brasileiro (NEB.

    Full Text Available A região de Piraju -- SP é caracterizada geologicamente por apresentar uma grande distribuição de rochas básicas e ácidas da Formação Serra Geral. Os processos e produtos de alteração das rochas básicas são apresentados em muitos trabalhos, mas estudos envolvendo alteração de rochas vulcânicas ácidas são raros. Apresentam-se os resultados de estudos petrológicos, químicos e mineralógicos nas rochas vulcânicas ácidas (riodacitos da Formação Serra Geral, nos produtos de alteração dessas rochas, dando ênfase para a evolução mineralógica dos plagioclásios. Os riodacitos da Fm. Serra Geral (JKsg possuem em sua composição mineralógica cerca de 60-65% de plagioclásios configurando assim a parte mais importante de sua constituição. O estudo da alteração desses plagioclásios oferece informações importantes em relação a própria alteração da rocha e dos solos relacionados. Resultados obtidos a partir de análises de microscopia óptica, difratometria de raios-X aliados a determinações químicas qualitativas e semi-quantitativas obtidas por microscopia eletrônica de varredura (MEV permitiram importantes interpretações e conclusões sobre a evolução da alteração nos plagioclásios, a saber: a por meio de intemperismo não muito intenso, isto é, processo de hidrólise parcial (monossialitização os cristais de plagioclásio evoluem principalmente para caulinita e secundariamente para mica e haloisita; b por meio de intemperismo intenso, isto é, processo de hidrólise total (alitização os cristais de plagioclásio evoluem para gibbsita.The Piraju (SP Brazil area is geologicaly characterized by a great distribution of basic and acid rocks from the "Serra Geral" Formation.

    Full Text Available As variações da temperatura e do fluxo de calor em solos sob a floresta nativa de Caxiuanã e uma pastagem natural da Ilha do Marajó, foram monitoradas continuamente no período de dezembro de 2001 a fevereiro de 2005. O objetivo foi comparar as respostas térmicas ao aquecimento diário, dos solos desses dois tipos de ecossistemas existentes no leste da Amazônia, para subsidiar modelos regionais de clima e avaliação dos efeitos de desmatamento. Além das medidas de campo das variáveis acima citadas, em três níveis até a profundidade de 0,5 m, esse trabalho apresenta estimativas de fluxo de calor e propriedades dos solos, tais como: difusividade e condutividade térmicas, profundidade de amortecimento e velocidade de propagação do pulso de aquecimento diário, determinados por métodos analíticos. Os resultados mostraram o contraste sazonal e outras diferenças significativas de respostas entre os dois sítios estudados, destacando o papel do conteúdo de água nos perfis térmicos verticais em cada tipo de solo. O ajuste obtido entre as medidas e os valores calculados das variáveis, indica a possibilidade de generalização dos resultados para outros sítios de ecossistemas similares na Amazônia.

    The Serra dos Órgãos batholith in the State of Rio de Janeiro (Brazil) is a NE-SW-trending elongated body that occupies ca. 5000 km2 in plan view. It is a foliated intrusion, especially at its borders and is crosscut by syn-magmatic shear zones, with foliations that are moderately-to steeply-dipping to the northwest and moderately-to shallow-dipping in the center and to the southeast, in a configuration of a large laccolith. It was emplaced between 560 and 570 Ma, during an extensional episode that was part of a series of events that comprise the Brasiliano Orogeny in SE Brazil, and which includes deformation, metamorphism and granite intrusion during the interval between 630 and 480 Ma. The two main rock types in the batholith are biotite-hornblende monzogranite, and biotite leucogranite, with subordinate tonalite, granodiorite, diorite, quartz diorite (enclaves), aplite and pegmatite. Harker-type diagrams help show two rock groups with similar trends of evolution: a dioritic and a granitic. The first one is tholeiitic, whereas the second is calc-alkaline, with medium-to high-K calc-alkaline affinity and metaluminous to slightly peraluminous character. In both groups strong decrease in Al2O3, MgO, FeOT and CaO relative to silica contents are observed, which is compatible with trends of fractional crystallization involving clinopyroxene and/or hornblende, plagioclase, opaque minerals, apatite, microcline and biotite. The Sr and Nd isotopic data suggest recycling of a Paleoproterozoic crust as an important petrological process to generate the batholith rocks. Geothermometry (amphibole composition) and geobarometry (saturation in zircon and apatite) indicate that most of the batholith solidified at mid to lower crustal levels at about 750 °C and between 5 and 5.5 kbar. We consider that Serra dos Órgãos crustal protoliths underwent melting caused by the interaction with hotter mafic magma at the base of the crust. These two magmas, with distinct initial

El bosque descrito como Podocarpo lambertii-Araucarietum angustifoliae consiste de un alto estrato arbóreo de Araucaria sola sobre un sotobosque, donde predominan mirtáceas juntos con Dicksonia sellowii . Principalmente, ocupa la parte más alta de las elevaciones entre 1400 y más de 1500 m de altitud s.n.m., y en su borde inferior contra los «campos» se observa una ­franja ± ancha de bosque quemado del cual sobrevive solamente el estrato de araucarias altas. De los «campos» se describe el Plantagini-Andropogonetum macrothrici como el pajonal que predomina en el paisaje. Se compone de 42 especies, en su mayoría geófitos. En sitios protegidos del fuego se estableció el matorral del Baccharido-Heterothalametum alieni que también invadió el bosque quemado.

    Full Text Available ResumoEste artigo tem como objetivo desafiar a lógica binária que permeia a discussão sobre o impacto da adesão da Turquia na política externa e de segurança comum (PESC da União Europeia (UE. Defende-se que qualquer análise sobre tal impacto precisa levar em consideração as divisões existentes dentro da Europa e dentro da Turquia em termos de culturas de segurança. Com o intuito de ilustrar a pluralidade de culturas de segurança existentes na UE e na Turquia e fornecer indicações sobre as potenciais contribuições do país para a Europa enquanto ator internacional, são analisadas as respostas da União Europeia como um bloco, de alguns países-membros europeus (França, Reino Unido e Alemanha e da Turquia ao conflito na Líbia em 2011. Conclui-se que, com ou sem a Turquia, a União Europeia deverá continuar a atuar como uma potência humanitária no cenário mundial e que, portanto, os potenciais impactos de uma eventual adesão turca não devem ser exagerados.

    The Serra de Tramuntana, which forms the backbone of the north-west of Mallorca (Spain), was declared in 2011 World Heritage Site by UNESCO under the cultural landscape category. The particular landscape of this range is the fruit of the exchange of knowledge between cultures, with small-scale works performed collectively for a productive aim, conditioned by the limitations imposed by the physical medium. The steep topography of the chain, highly related to its geological complexity, and the Mediterranean climate, influence intense slope dynamics with the consequent multiple types of slope failures: rock slides, earth landslides and rockfalls, which cause significant damage and specifically to the road network (Mateos, 2013a). The human landscape marked by agricultural terraces (dry stone constructions) has significantly contributed to the slope stability in the range for centuries. In the present work, a landslide inventory map with 918 events has been updated and the landslides state of activity was analyzed exploiting 14 ALOS PALSAR satellite SAR (Synthetic Aperture Radar) images acquired during the period 2007-2010. Landslide activity maps were elaborated through the use of PSI (Persistent Scatterers Interferometry) technique (Bianchini et al., 2013). Besides assessing the PS visibility of the study area according to the relief, land use and satellite acquisition parameters, these maps evaluate, for every monitored landslide, the average velocities along the satellite Line Of Sight (VLOS) and along the maximum local steepest slope (VSLOPE), providing an estimate of their state of activity and their potential to cause damages. Additionally, a ground motion activity map is also generated, based on active PS clusters not included within any mapped landslide phenomenon. A confidence degree evaluation is carried out to attest the reliability of measured displacements to represent landslide dynamics. Results show that 42 landslides were identified as active (VSLOPE

    Atlantic Forest, in the eastern coast of Brazil, is a hotspot of biodiversity of mammals, and Parque Estadual da Serra do Mar (PESM) is the largest continuous area of this biome. Here, we characterized the karyotype composition of the small mammals from Santa Virgínia, a region in the northern part of PESM. Specimens were collected from July 2008 to September 2009. We identified 17 species (13 rodents and 4 marsupials) from which 7 exhibited species-specific karyotypes, illustrating the importance of karyotype information in cytotaxonomy. We report for first time the karyotype of Monodelphis scalops (Thomas, 1888) and two new records for PESM: Akodon montensis Thomas, 1913 and Brucepattersonius soricinus Hershkovitz, 1998. Cytogenetic polymorphisms were detected for some species trapped in the area. Our results show the importance of Santa Virgínia / PESM in addressing studies for the conservation of small mammal wildlife in the Atlantic Forest.

We report for first time the karyotype of Monodelphis scalops (Thomas, 1888 and two new records for PESM: Akodon montensis Thomas, 1913 and Brucepattersonius soricinus Hershkovitz, 1998. Cytogenetic polymorphisms were detected for some species trapped in the area. Our results show the importance of Santa Virgínia / PESM in addressing studies for the conservation of small mammal wildlife in the Atlantic Forest.

    Full Text Available The objective of this study was to analyze the gonadossomatic relation of males and females of Brycon opalinus (the Pirapitinga do Sul in the Serra do Mar State Park-Núcleo Santa Virgínia. The study area included three rivers: Paraibuna, Ipiranga, and Grande. From the gonadossomatic relation, it was possible to determine the reproductive season and strategy of this species. The gonadossomatic relation was high throughout the year for both males and females. Sperm competition and dilution of the ejaculate in the spawning locations favored substantial development of the testicles. The sex ratio of Brycon opalinus was always in favor of females. The existence of sexual dimorphism in this species was confirmed from the larger size of the females.

    Abstract Atlantic Forest, in the eastern coast of Brazil, is a hotspot of biodiversity of mammals, and Parque Estadual da Serra do Mar (PESM) is the largest continuous area of this biome. Here, we characterized the karyotype composition of the small mammals from Santa Virgínia, a region in the northern part of PESM. Specimens were collected from July 2008 to September 2009. We identified 17 species (13 rodents and 4 marsupials) from which 7 exhibited species-specific karyotypes, illustrating the importance of karyotype information in cytotaxonomy. We report for first time the karyotype of Monodelphis scalops (Thomas, 1888) and two new records for PESM: Akodon montensis Thomas, 1913 and Brucepattersonius soricinus Hershkovitz, 1998.

    Full Text Available The ecology of anopheline species (Diptera, Culicidae was studied in the vicinity of the Serra da Mesa Reservoir, State of Goiás, Brazil. Climatic factors and frequency of anopheline populations were analyzed. Bimonthly human-bait and Shannon trap captures were conducted for 36 consecutive months (January 1997 through December 1999. A total of 5,205 adult anophelines belonging to five species were collected. Anopheles darlingi was the most frequently collected anopheline (61.4%, followed by An. albitarsis s.l. (35.4%, An. triannulatus. (2.5%, An. oswaldoi (0.4%, and An. evansae (0.2%. The water level and vegetation along the banks of the reservoir were crucial to the frequency of the various anopheline species. Climatic factors had a secondary influence. The reservoir's water-level stability, increased frequency of An. darlingi, and the arrival of gold prospectors were responsible for the increase in malaria cases.

    A multi-proxy geochemical study of surficial sediments of an upland lake (Amendoim Lake), located in the Serra dos Carajás region, Brazil, was carried out to understand catchment weathering and provenance of sediments in the basin, as well as sedimentary processes. The carbon and nitrogen isotopic compositions of organic matter in the sediment were quite homogeneous, and suggest that the organic sources for this lake are mainly composed of palms and submerged macrophytes. The R-mode factor analysis indicates that most of the trace elements, including rare earth elements (REEs), are clustered with Al (Group 1), Si is grouped with Zr and Hf (Group 4), total organic carbon (TOC) with TS and Hg (Group 2), and Fe with Mn and As (Group 3). The elements of the Group 1 show strong positive correlations with Al, suggesting that these elements are hosted in detrital minerals during laterization in the catchment basin and not significantly affected by diagenesis. The high CIA values (96-99) of sediments together with their position in A-CN-K and log (Fe2O3/K2O) vs log (SiO2/Al2O3) plots indicate intense chemical weathering in source area. However, similar geochemical signatures between lake sediments and catchment lateritic crust indicates that mechanical erosion was the dominant sediment formation process. REE patterns normalized to chondrite along with geochemical indices (Al/K, Al/Ti, La/Th, La/Al, Ti/Zr, Zr/Hf, Th/Sc, Co/Th, Ba/Sr, and Eu/Eu*) also indicate that the sediments are mainly derived from laterite crust. This study provides reliable background information to reconstruct weathering processes and lake evolution in the Serra dos Carajás area.

Ambos já tinham prestígio em suas áreas, o que resultou em um embate de ideias bem fundamentadas e franca-mente divergentes, cujas colateralidades procuraremos investigar. Destacam-se da entrevista as suas discussões centrais: parte-se das diferentes noções que os artistas possuem acerca das origens da escultura modernista, passando pelas considerações sobre alusão na escultura e arquitetura americanas, desdobrando-se finalmente em distintas posições dos autores acerca do método de produção de suas obras e suas relações com o sítio. Ademais, analisa-se a entre-vista na sua contribuição ao debate geral dos artistas nos anos oitenta, e em seus auspícios quanto às fronteiras entre escultura e arquitetura.This article concerns an interview with the North American artist Richard Serra (1939- conducted by Peter Eisenman (North American architect, 1932- in 1983. Both artists were already prestigious in their areas, and that resulted in a deep and diverging debate, whose aspects will be investigated. This article starts with a study of the main issues of the interview: the different notions each artist had embracing the concept of modern sculpture, the question of allusion in sculpture and architecture, their divergences on their ways of developing their work, and how they interact with the site. Moreover, this interview was interpreted in its contribution to the overall discussion on art and architecture, and in its auspice on the borderline between sculpture and architecture.

    Full Text Available In the São Marcos (RS and Antonio Prado (RS, the Serra Geral Formation exposes at the base basalts of pahoehoe type, coveredby basalts of the ´a´ā type. The first succession was generated by a low rate of eruption in a closed flow system allowed the flow toreach distances > 100 km of the source.T he ´a´ā lava flow types were generated by higher rates of eruption andt ransported in openchannels where rapid cooling prevented long distances from the source to be reached. The two types of basalts are low-TiO2 tholeiiticand the morphology of flows is not related to variations in SiO2 and MgO contents. Above these rock types outcrop acidic volcanicrocks geochemically of Caxias Group (Palmas Subgroup. Dimension stones extraction exposed the inner portions of the acidicfeeder dikes with vertical magmatic foliations. The lava domes have exogenous characteristics and horizontal foliations. We proposea model for the generation of domes involving the diapirically rise of acids magmas that become vesicular and more viscous, thatstop near the surface. New magmatic pulses extracted “pieces” of the vesicular fraction generating autobreccias in the conduit andvertical structures that extend laterally toward the surface organizing the lava domes with vitrophyres in the base and in the top, witha thin massive phaneritic core. Magmatic textures of the domes are typical of effusive units and the identification of the feeder dykesin the area allows the understanding of the emplacement process of acidic flows in the Serra Geral Formation.

    Full Text Available INTRODUÇÃO: A eficácia da ressecção em bloco duodenopancreático para tumores infiltrativos não periampulares ainda não está bem definida³, mas sabe-se que em tumores colorretais localmente avançados, a ressecção multivisceral é, na maioria das vezes, a chance de melhor qualidade de vida4. OBJETIVO: apresentar um caso de neoplasia de cólon direito com invasão duodenopancreática tratado com gastroduodenopancreatectomia. RELATO DE CASO: Paciente de 73 anos, branco, que há oito meses apresentava astenia, adinamia e emagrecimento de aproximadamente 20 kg. Ao exame físico: IMC: 20,3, descorado ++/4. Abdome com massa palpável em flanco direito de aproximadamente 15cm. A colonoscopia demonstrou tumor de cólon direito e o anátomo-patológico evidenciou adenocarcinoma moderadamente diferenciado. A Tomografia computadorizada demonstrou os vasos mesentéricos livres de invasão. No intra-operatório se observou massa tumoral envolvendo cólon ascendente até ângulo hepático invadindo segunda para terceira porção duodenal. Foi realizada colectomia direita associadaà gastroduodenopancreatectomia em bloco. O anátomo-patológico da peça revelou adenocarcinoma moderadamente diferenciado de intestino grosso com metástases em tecido duodenal e pancreático com infiltração angio-linfática. O paciente sobreviveu por 8 meses. CONCLUSÃO: A gastroduodenopancreatectomia deve ser considerada para tumores não periampulares na ausência de metástases à distância e quando a condição clinica do paciente permitir e foi a conduta adequada para este paciente.INTRODUCTION: The effectiveness of duodenopancreatic ressection in block for infiltrative periampolar tumors are not yet know, but it is known that in local advanced colorretais tumors, the multivisceral ressection is, most of the time, the possibility of better quality of life.

    Full Text Available A grande procura de órgãos para transplante tornou necessária a aceitação de potenciais doadores pediátricos a fim de aumentar a oferta. Trabalhos anteriores relatando menor sobrevida do enxerto e taxas maiores de complicação fizeram com que cirurgiões considerassem o assunto com cautela. Esse é um estudo retrospectivo com o objetivo de analisar os resultados de transplantes renais em bloco de doadores infantis (The high demand for organs for transplantation has made it necessary to consider using the youngest of potential donors in order to increase the organ supply. Previous reports of decreased graft survival and increased complication rates have made surgeons wary of using such kidneys. This is a chart review with the objective to analyse the results achieved with transplantation of children kidneys (< 2 years in the HCFMRP-USP from 1998 to 2000. A total of 5 pacients received en bloc renal transplants from donors aged 9 months to 2 years old, weighthing between 8 and 14 kg. Results: Only one patient lost the allograft within 8 days of transplantation due to allograft trombosis. Two patients had ureteral complications, one with ureteral necrosis and urinary fistula and the other with total ureterovesical anastomosis disrupture. Both were successfully repaired. Intra operatory complication was experienced in one pacient, with arterial anastomosis rupture. In loco reperfusion and repair was made. Another patient had inferior renal pole rupture, treated with polar nefrectomy at the 4º PO. Despite such problems, mean follow up of 20,7 months showed serum creatinine ranging from 0,9 to 2 mg/100ml, with no serious complications. Conclusion: Our data support the use of en bloc child cadaveric kidneys, even from infant donors less than two year of age, when the organ necessity supplant the higher rates of complications.

    Full Text Available In Santa Fe, the central-east area of Argentina, the expansion of fruit tree crops requires the introduction and evaluation of low chilling varieties. The aims of this study was to characterize the phenological behaviour and the reproductive traits of peach (Prunus persica L. Batsch and nectarine varieties with chilling requirements ranging from 150 to 650 chilling hours (CH. Low chilling varieties (500 CH. The phenology of high chilling requirement varieties had the advantage that blooming and fruit set happened after the period of late frost occurrence. However, they did not satisfy their chilling requirement, showing an inadequate vegetative and reproductive behaviour. Low chilling varieties began to sprout during July, and the period of full bloom occurred from July 14th to August 4th. Fruit harvest was initiated on October 19th with the cv. 'Flordastar' and it extended for 58 days. However, on low chilling varieties the harvest time was reduced in ten days. Flower density, fruit set and fruit yield showed a negative relationship with the chilling requirement of the variety.Na região centro-leste do estado de Santa Fé, Argentina, para a expansão dos frutais é preciso introduzir variedades de baixo requerimento de frio.

    Full Text Available No Brasil, o número de plantios comerciais de espécies florestais de crescimento rápido vem aumentando consideravelmente nas últimas décadas. Contudo, os possíveis impactos desse aumento sobre os recursos hídricos ainda são desconhecidos. O objetivo deste estudo foi realizar a modelagem do balanço hídrico em uma microbacia cultivada com plantio comercial de híbridos de Eucalyptus grandis x urophylla no Leste de Minas Gerais, Brasil. O trabalho foi realizado em uma microbacia experimental com área total de 40 ha durante o ano hidrológico, compreendido entre outubro de 2009 e setembro de 2010. A principal entrada de água no sistema via precipitação pluvial e os dados meteorológicos foram coletados por uma estação automática instalada no interior da área de estudo. As principais saídas foram estimadas pela equação modificada de Penman-Monteith e pela mensuração do deflúvio gerado na saída da bacia. Do total precipitado (1.123 mm durante o ano, 9% (106 mm retornaram à atmosfera via interceptação, 66% (740 mm via transpiração da cultura e 11% (119 mm pela evaporação do solo, que somados corresponderam à aproximadamente 86% da entrada de água na microbacia. Do deflúvio total gerado (~147 mm, apenas 4,29 mm (0,4% foram convertidos em escoamento superficial. Pode-se concluir que durante o ano hidrológico monitorado o balanço entre as principais entradas e as saídas de água na microbacia foi equalizado, não comprometendo a disponibilidade hídrica natural no curso d'água.

    Full Text Available This paper approaches the recent strategies of building construction in the metropolitan area of Vitoria (RMGV. It focuses on the transformations of urban space in the municipality of Serra-ES, whose urban dynamics was related historically to the peripheral expansion of the metropolis since 1970. Thus, the forms of housing construction were articulated, above all, with the reproduction of the lower income population, such as lots and housing for the working class. In recent years, the city is a privileged stage for real estate investment materialized in new spatial forms, such as horizontal and vertical condominiums. In the real estate dynamics of the metropolis, Serra emerges as another front in the performance of real estate capital, which is based on promoting a new product in the State of Espírito Santo market, gated communities and image associated with security, access to nature etc. The activity of capitalist building production in the city is marked by new relations promoted by large corporations, publicly traded on the stock exchange, which establish partnerships with local companies.

Dentro deste contexto, as cavidades naturais da Serra da Piedade foram objeto de estudo, que tem como principal objetivo levantá-las e classificá-las, de acordo com seus aspectos morfológicos e genéticos, assim como analisar sua distribuição ao longo do relevo. Para isso, os seguintes procedimentos metodológicos foram realizados: (i revisão bibliográfica, (ii caracterização da área de estudo; (iii compartimentação do relevo; (iv prospecção e análise em campo dos aspectos morfológicos e genéticos; (v mensuração da projeção horizontal das cavidades, através de medidas realizadas em campo e mapeamento topográfico; e (vi análise e discussões dos resultados. Os resultados obtidos evidenciaram que existem três tipos de cavidades na Serra da Piedade: cavernas em tálus; cavernas com feições cársticas e cavernas onde não foi possível constatar evidências morfocársticas. De maneira geral, as cavidades formadas por acumulação de matacões encontram-se nos patamares altimétricos mais elevados, entretanto, estão situadas numa declividade relativamente suave. Já grande parte das cavernas sem evidências morfocársticas e das cavernas com feições cársticas estão localizadas na borda do platô de canga. Entretanto, a caverna cárstica de maior projeção horizontal está inserida no interior da unidade escarpa norte. Quanto ao desenvolvimento das cavernas topografadas, constatou-se que aquelas com feições cársticas são maiores do que as cavernas sem evidências morfocársticas.  Pode-se concluir que existem processos de carstificação em cavernas e feições superficiais desenvolvidas no itabirito e na canga, embora as mesmas não sejam tão desenvolvidas como as feições presentes em rochas carbon

    Full Text Available Recentemente foram introduzidos novos medicamentos no tratamento da esclerose múltipla (EM capazes de modificar a história natural da doença. Nos estudos clínicos que avaliam estas drogas utiliza-se com frequência a escala de incapacidade expandida (EDSS como instrumento para avaliar as disfunções e incapacidades neurológicas durante estes ensaios. Há inúmeras limitações no uso desta escala, predominantemente pelo fato desta ser uma escala que privilegia em demasia a capacidade de marcha dos pacientes. Neste estudo, apresentamos nossos resultados na aplicação do teste de destreza manual da caixa e blocos em indivíduos normais e em portadores de EM. Observamos que 64,8% das mulheres e 80,7% dos homens apresentaram alterações estatisticamente significantes no escore deste teste quando comparados com indivíduos normais. Por sua facilidade de aplicação e sensibilidade em detectar alterações das habilidades motoras em membros superiores, os autores recomendam o emprego deste teste na avaliação do efeito destes medicamentos em pacientes com EM.Recently new disease-modifying treatments for multiple sclerosis (MS were introduced wich can change the natural course of the disease. In clinical trials with these new agents the Expanded Disability Status Scale (EDSS is often used as a primary outcome instrument to measure neurological impairment and disability. A number of limitations have been identified when using the EDSS, some of wich are because the EDSS is an ordinal scale that is heavily biased to locomotor function. In this study we applied the box and block test of manual dexterity in normal subjects and relapsing-remitting MS patients. The results were that 64.8% of the female and 80.7% of the male patients had significant changes on this task compared with normal subjects, and as this test is easily applied and is sensitive in detecting upper extremity functional ability, we recommend its use in clinical trials to evaluate

    Full Text Available O reparo de fístulas oronasais representa um desafio para o cirurgião, devido à freqüente ocorrência de recidivas. Com o intuito de avaliar o emprego de osso bovino esponjoso inorgânico liofilizado em bloco (OBEILB no tratamento dessa afecção, foi realizado um experimento utilizando dez cães sem raça definida, fêmeas com peso variando entre 8-17kg, submetidos à indução de fístulas oronasais após exodontia dos caninos. O procedimento cirúrgico foi realizado em duas etapas: na fístula do lado esquerdo, foi feito reparo imediato após realização do defeito, e, no lado direito, o reparo foi efetuado após sete dias, ambos preenchidos com OBEILB e recobertos com retalho de mucosa de origem gengival. Os animais foram avaliados clínica e radiograficamente, semanalmente, entre sete e 120 dias. O material usado é eficaz no reparo de fístulas oronasais do alvéolo do dente canino maxilar, não apresentando evidências de rejeição e recidivas.The oronasal fistula repair still represents a challenge to the surgeons, due to the high incidence of recidivation. An experiment using 10 adult mongrel dogs weighting between 8 and 17 kilograms was performed in order to evaluate the in block lyophilized inorganic bovine bone cancellous (BLIBBC in the treatment of this disease. Each dog had an exodontic procedure of both canine teeth, in order to produce an oronasal fistula. The surgical procedure realized consisted in two different surgical steps: the left side defect was repaired right after the defect have been produced, while the right side defect was repaired seven days after the fistula induction; both sides were repaired using BLIBBC and covered with gengival flap. The animals were radiological and clinicaly evaluated every week for 120 days. The material used was effective in the repair of both fistulas, without rejection or recurrence.

    Full Text Available http://dx.doi.org/10.5007/2175-795X.2016v34n2p365 O presente artigo visa à sistematização dos resultados de estudos preliminares sobre os desafios e possibilidades de desenvolvimento de um trabalho de cooperação internacional compartilhada em Timor-Leste. Nesse sentido, partindo da problematização do papel da Cooperação Internacional para o Desenvolvimento nos países em desenvolvimento, tem-se como hipótese inicial que, após a restauração da independência, em 2002, e com a chegada das agências internacionais de cooperação, que aportaram em Timor-Leste com o objetivo de “ajudar” na construção do Estado-Nação, o maior desafio que o país vive é o enfrentamento da contradição entre, por um lado, atender às exigências das agências internacionais, capitaneadas pela Organização das Nações Unidas e pelo Banco Mundial, para colocar o Estado timorense e suas instituições nos trilhos da “globalização” e, por outro, defender e preservar sua identidade cultural. Portanto, com base em estudos de natureza bibliográfica, nos pressupostos teórico-metodológicos da dialética marxista e no pensamento de Paulo Freire, bem como na experiência vivida pelos autores por meio do Programa de Qualificação de Docentes e Ensino de Língua Portuguesa em Timor-Leste, conclui-se que o compromisso, a vontade política e o respeito pelas diferenças culturais entre os agentes envolvidos nas ações de cooperação são ingredientes necessários para superar os desafios e avançar na construção de uma relação de cooperação internacional compartilhada.

    This is the first record of a Permian seep deposit and an associated, morphologically bizarre, bivalve-dominated fauna from the Passa Dois Group, Paraná Basin, Brazil. Shales of the outer-shelf facies of the Serra Alta Formation preserve a low-diversity but high-abundant, large-sized bivalve fauna with unusual morphologies inside discoidal carbonate concretions. The bivalves are about ten times larger than tiny bivalves found scattered in laterally equivalent mudstones of the same unit. Intercalated between two concretion-bearing horizons, a cm-thick, sheet-like, disrupted, ;brecciated;, partially silicified carbonate layer with microbially-induced lamination is recorded. In some areas, the carbonate layer shows vertical structures formed by injections of mud mixed with white limestone clasts and microbial linings. Immediately above this, silicified mudstones preserve small domal structures (= mounds) with a slightly depressed center. Monospecific concentrations of closed articulated shells of Tambaquyra camargoi occur at the base of these domes. Carbon-isotope (δ13C) values from the shells, ;brecciated; carbonates, and fossil-rich concretions are all depleted (negative values ∼ -6.1 to -7.6‰). Combined taphonomic, sedimentological, petrographic, geochemical and paleontological data suggest that the disrupted, ;brecciated; carbonate and associated fauna and domes may have formed by an exudation system. Indeed, this interval of the Serra Alta Formation is ∼8.7 m above the contact with the underlying, oil-rich Irati Formation. This unit has very high total organic carbon (up to 23%) values and high sulphur contents, supporting the interpretation of the lithological and paleontological features as result of seepage of organic compounds at the seafloor. Where the gases and hydrocarbons escaped, the seabed was colonized by, at least facultatively, chemosymbiotic bivalves. The species above belong to a highly endemic group of pachydomids that were shallow

    Full Text Available The forest formations on quartz white-sand are a kind of oligotrophic ecosystem and its phytophysionomical characteristics are affected by the climate seasonality. The canopy is one of these characteristics, its variations may influence the spatial distribution of the energy in the environment. The objective of this research was to evaluate and compare the tree density and the seasonality change on the canopy openness on habitats of white-sand in Serra de Itabaiana National Park. The data were collected in two environments: gaping vegetation of white-sands strictu sensu (VA and closed vegetation of riparian forest (MR. To estimate tree density, it was utilized the wandering-quarter, where trees with CAP > 5cm were sampled. To evaluate the canopy dynamics, the transects had 5 points equidistant 20m, ten per environment. Hemispherical pictures were taken in January (dry season and June (wet season, utilizing a digital camera with a fisheye lens. The images were analyzed on the Gap Light Analyzer software. The results showed that riparian forest have higher tree density (498 ind ha -1 than the opened (296 ind ha -1 . The letter do not showed variations in the canopy openness ( t = -2,0052; p > 0,05 or in Leaf Area Index ( t = -2,0052; p > 0.05 between wet (52,24% ± 18,13% e 0,68 ± 0,45 and dry seasons (67,39% ± 15,38% e 0,36 ± 0,23. In riparian forest, the canopy openness ( t = 7,1739; p < 0.05 and LAI values ( t = -5,1609; p < 0.05 vary between wet (13,70% ± 2,24% e 2,13 ± 0,23 and dry (21,08% ± 2,36% e 1,63 ± 0,20 seasons showing the seasonality. Differences between the two habitats highlights the environmental heterogeneity in Serra de Itabaiana and show that forest formations on white-sand respond by different ways to the water seasonality of this ecosystem. Because it is located in an ecotone area between evergreen forest and forest Semideciduous, the riparian forest tends to lose some of their leaves during the dry season. Moreover

    Full Text Available Apesar de o interesse no comportamento espacial de atributos-chave do solo, só recentemente a variação em profundidade passou a receber mais atenção na literatura. O carbono orgânico do solo (COS é talvez o atributo que mais varie em profundidade, o que dificulta seu estudo. A partir de dados de levantamentos de solos de duas regiões de Minas Gerais (Sul e Serra do Espinhaço Meridional, foram modelados os teores de COS em profundidade, buscando identificar quais fatores mais os influenciam. Os perfis de COS foram mais bem descritos por funções logarítmicas neperianas em ambas as regiões. Houve efeito da classe de solo, uma vez que Latossolos apresentaram menores teores superficiais, mas menor decréscimo no perfil, do que Argissolos, Neossolos, Cambissolos e Nitossolos. Essas tendências podem ser devidas à maior profundidade, permeabilidade e teor de argila+silte dos Latossolos. A variação regular dos parâmetros intercepto (teor médio na superfície e fator logarítmico (taxa de decréscimo das equações obtidas para diferentes faixas de teor de argila+silte permitiu ainda obter funções de pedotransferência em perfil para descrever teores de COS em profundidade em qualquer classe de solo, confirmando a hipótese de que a textura é um controle importante dos teores de COS nessas duas regiões. Na região Sul de MG, os perfis de COS puderam também ser descritos em função de teores de Fe2O3 (ataque sulfúrico, evidenciando controle mineralógico do COS. Ainda na região Sul, solos entre 1.000 e 1.200 m de altitude apresentaram maiores teores de COS do que os de altitudes menores. Latossolos e Nitossolos das duas regiões mostraram perfis muito semelhantes de COS - similaridade atribuída ao efeito positivo de maiores teores de argila na região Sul e maior altitude na Serra do Espinhaço Meridional.

    Full Text Available A Reserva Biológica Municipal Serra dos Toledos é um importante remanescente de Mata Atlântica no sul de Minas Gerais, com elevada biodiversidade e riqueza em recursos hídricos. Estudos relacionados à qualidade de solos são necessários em planos de manejo de reservas, os quais objetivam manter ou melhorar a sustentabilidade ambiental dessas áreas. Assim, o objetivo do presente trabalho foi avaliar o potencial de inóculo de fungos micorrízicos arbusculares (MAs em amostras de solo características desta Reserva. A quantificação de propágulos desse grupo de micro-organismos, que estabelecem simbiose mutualística com a maioria das espécies vegetais é importante para a avaliação da qualidade de solos da Reserva. Foram definidas três áreas internas e uma externa à Reserva, retirando-se amostras de solo na profundidade de 0 a 10 cm, em duas épocas, inverno de 2008 e verão de 2009. As amostras foram encaminhadas ao Laboratório de Microbiologia da Universidade Federal de Itajubá para quantificação dos seguintes atributos microbiológicos relacionados aos fungos MAs: comprimentos de micélio extrarradicular ativo e total pelo método da fluorescência induzida com diacetato de fluoresceína, densidade e diversidade fenotípica (morfotipos de esporos, porcentagem e intensidade de colonização radicular. As médias dos resultados foram comparadas por Duncan 5% e submetidas à análise de multivariada. Os resultados mostraram que o potencial de inóculo de fungos MAs apresentou maior efeito das áreas que das épocas estudadas, sendo maior comprimento de micélio extrarradicular ativo e total, maior proporção de micélio ativo em relação ao total e maior diversidade de esporos obtidos nos solos dentro da Reserva Biológica Municipal Serra dos Toledos, em relação ao solo externo à mesma, sob pastagem. O potencial de inóculo não está diretamente relacionado à fertilidade do solo, ou seja, no solo externo à Reserva, sob

    In order to understand the causes of erosion before the construction of protective structures on erosional beaches of northeastern Brazil where the Macau/Serra oil field (Potiguar Basin) are installed, environmental studies based mainly on in situ measurements of hydrodynamic and beaches profiles data were undertaken as part of MARPETRO project (FINEP/CTPETRO/PETROBRAS). The data were collected monthly during a period of 24 months (October 2000 to September 2002), always in the spring tides. The beach profiles analysis show an intensive surface erosion rate, as observed by the decrease of the berm scarp in the profile 03, which retreat more than 17 meters in this period. Hydrodynamic data indicate a decrease in the period of erosion x deposition, as verified in the overlap of the topographic profiles. The results show that due to the high environmental sensibility of the area, which has a negative natural impacts while the human interference just accentuate the erosional processes. (author)

    Diego Fernando Ducart

    Full Text Available ABSTRACT: Mapping methods for iron oxides and clay minerals, using Landsat-8/Operational Land Imager (OLI and Earth Observing 1 (EO-1/Hyperion imagery integrated with airborne geophysical data, were applied in the N4, N5, and N4WS iron deposits, Serra Norte, Carajás, Brazil. Band ratios were achieved on Landsat-8/OLI imagery, allowing the recognition of the main minerals from iron deposits. The Landsat-8/OLI imagery showed a robust performance for iron oxide exploration, even in vegetated shrub areas. Feature extraction and Spectral Angle Mapper hyperspectral classification methods were carried out on EO-1/Hyperion imagery with good results for mapping high-grade iron ore, the hematite-goethite ratio, and clay minerals from regolith. The EO-1/Hyperion imagery proved an excellent tool for fast remote mineral mapping in open-pit areas, as well as mapping waste and tailing disposal facilities. An unsupervised classification was carried out on a data set consisting of EO-1/Hyperion visible near-infrared 74 bands, Landsat-8/OLI-derived Normalized Difference Vegetation Index, Laser Imaging Detection and Ranging-derived Digital Terrain Model, and high-resolution airborne geophysical data (gamma ray spectrometry, Tzz component of gradiometric gravimetry data. This multisource classification proved to be an adequate alternative for mapping iron oxides in vegetated shrub areas and to enhance the geology of the regolith and mineralized areas.

    Biodiversity studies allow ecosystem assessment and monitoring of environmental changes and impacts. Parasite diversity could reflect the host/ parasite coevolutionary process and the environment changes that permit the loss, gain or maintenance of species. This survey used species/morphotypes of helminths eggs found in feces from seven wild mammal species (the groups Dasypodidae and Large Cats, and Tamandua tetradactyla, Cebus apella, Alouatta caraya, Cerdocyon thous, Pecari tajacu) and from two domestic species (Canis familiaris and Sus scrofa), which occur within the Serra da Capivara National Park (PNSC) and surrounding areas in order to analise the diversity of mammal intestinal helminths. This work used the helminthological fauna findings of wild and domestic mammals, to consider a possible helminth flux between these two host groups using Unweighted Pair Group Method with Arithmetic Mean (UPGMA) of the hosts based on helminthological fauna composition. The results indicate that the region of the PNSC still maintains environmental conditions that still keep wild mammal helminthological fauna composition different from the one found for domestic mammals.

    During two full years--from October 1980 to September 1982--we captured sandflies in the National Park of Serra dos Orgãos, State of Rio de Janeiro, Brazil. The captures, with human bait, were carried out weekly, each with a duration of two hours, and at three different times (6 to 8 a.m., 5 to 7 a.m. and 7:30 to 9:30 p.m.). In every capture, we recorded the phase of the moon and, at each hour, the temperature, relative humidity, wind and rain. In 586 hours 4,834 sandflies of ten species were captured, all belonging to genus Lutzomyia França, 1924. L. ayrozai and L. hirsuta represented 92% of the total species captured. However, they were dominant at different times, the former being more frequent in the warm and wet months, and considerably declining in the cold and dry months, in which the latter gradually prevailed. L. fischeri and L. shannoni were shown to be the most resistant to unfavourable weather conditions. Whenever there was any rain or wind, they were, in general, the only species captured. With regard to lunar cycle, we observed that new moon was the most favourable phase for the capture of sandflies and full moon the one with the smallest yield, except for L. shannoni which occurred more frequently during this period.

    Full Text Available In February 2001, an accidental spill dumped 52,000 litres of diesel oil in Serra do Mar, Paraná state, Brazil, contaminating streams. This study aimed to evaluate if fish communities currently inhabiting environments exposed to the oil spill still showing evidence of spill-related impacts. Ichthyofauna communities were monitored in five rivers located in the region of the spill. Two sites exposed to oil (Meio and Sagrado rivers were considered treatment sites, and three unexposed sites with environmental characteristics similar to the treatment sites (Pinto, Passa Sete and Marumbi rivers were considered control sites. Analysis of water quality parameters indicated that sites within rivers were more similar than sites among rivers. The diversity and species composition of fish communities differed between the treatment and control groups and among the rivers. The distribution and species composition of ichthyofaunal communities likely reflect the environmental characteristics of each river and not related to the environmental contamination resulting from the oil spill.

Systematized biweekly human bait collections were made three times a day, for periods of 2 or 3 h each, in sylvatic and rural areas for 24 consecutive months (January 1991 to December 1992. A total of 24,943 adult mosquitoes belonging to 57 species were collected during 622 collective periods. Aedes scapularis, Coquillettidia chrysonotum, Cq. venezuelensis, Wyeomyia dyari, Wy. longirostris, Wy. theobaldi and Wy. palmata were more frequently collected at swampy and at flooded areas. Anopheles mediopunctatus, Culex nigripalpus, Ae. serratus, Ae. fulvus, Psorophora ferox, Ps. albipes and the Sabethini in general, were captured almost exclusively in forested areas. An. cruzii, An. oswaldoi and An. fluminensis were captured more frequently in a residence area. However, Cx. quinquefasciatus was the only one truly eusynanthropic. An. cruzii and Ae. scapularis were captured feeding on blood inside and around the residence, indicating that both species, malaria and arbovirus vectors respectively, may be involved in the transmission of these such diseases in rural areas.

    Full Text Available The structure of western Serra do Curral, Quadrilátero Ferrífero, represents the partial exposure of a syncline that verges to NNW – Piedade Syncline. This regional structure has parasitic folds denominated as B1A which are refolded by folds B1B that also have vergence to NNW. Both of them have ENE-WSW direction, are non-cylindrical folds and configure an interference pattern that is similar to Type 3 from Ramsay. This refolding occur during progressive deformation. The occurrence of high-grade magnetitic-martitic accumulation (> 64% Fe of medium size (~ 100 Mt is controlled by the combination of these folds and high angle thrust fault, both with the same direction. Above these structures, there is a development of folds with NNW- SSE direction and WSW vergence (B2 folds. These folds are restricted to the B1 limbs and they configure an interference pattern named “abbuting fold”. The age obtained by U/Pb SHRIMP on monazite grains is 2034±11 Ma. The monazite grains occur on textural balance with the iron oxide from high-grade accumulations. This age corresponds to the formation timing of the high-grade bodies and suggests that the mineralization process is contemporary to the regional metamorphic peak of Quadrilátero Ferrífero.

Including other author’s data, it was possible to reveal that Ilex microdonta is the most important species, followed by Drimys brasiliensis, Ocotea catharinensis, Blepharocalyx salicifo lius and Gordonia fruticosa. It was observed the high arborous density, with more than 4.490 trees per hectare, which configures a single stratum, and medium height of 4 m. On cluster analysis the best results were obtained by using the Importance Value. The minor stand similarity was registered among the sites on “morro do Araçatuba” (1.610 m and “morro do Vigia” (1.280 m, indicating that the altitude factor has a powerful influence on this aspect. Although the Jaccard´s index for all the sites revealed that despite of the structure significant differences, in relation to the floristic all of these were considered similar.

    Full Text Available This study was conducted for Pinus elliottii Engelm. at Serra do Sudeste, Rio Grande do Sul, with the following objectives: to check production costs and possible revenues; to perform the economic and financial analysis of Pinus elliottii's wood production under regional conditions; and to determine the rotation of maximum Net Present Value (NPV. The costs for planting the stands were estimated at $2,292.09/ha and the annual maintenance ranged from R$ 134.84 to R$ 363.98 per hectare. Departing from the Site Index 28, with NPV of R$ 1,147.17/ha, Pinus' wood production becomes interesting. At the IS 26, with 6.86% Internal Rate of Return (IRR, it would be possible to pay the 6.75% Propflora's interest. Analysis of different rotations for IS 28 showed maximum VPL with rotation of 26 years, thinning in cycle of 4 years, starting up the cuts to 10 years. The economic analysis was performed with considerable caution, using productivity moderated levels, costs within patterns that can be considered between middle and high and moderated prices for today's wood market. Even with the restrictions imposed on the analysis, results are promising; especially in view of the regional market prices' increase tendency and the probability of wood veneer industries comes to absorb the larger log's size production in a closed future.

  2. Composition and relative abundance of terrestrial medium- and large-sized mammals of Parque Estadual da Serra do Brigadeiro, Minas Gerais, Brazil

    2012-09-01

    Full Text Available Three northern areas of Parque Estadual da Serra do Brigadeiro (PESB were sampled for terrestrial medium- and large-sized mammals, using camera traps, for twelve months. Nine wild species and one domestic species were registered, through 49 records. The community’s composition was based on an exponential series with dominance of few species. In contrast, there was a relatively high proportion of species that might be “rare” in the community observed, with dominance of puma (Puma concolor over the other ones. The results show that the area named Vale Perdido is the most important one for the conservation of mammals, because the estimated species richness is higher there (13.99 ± 2.23 when compared to that of the other two areas, which had a richness of 6.00 ± 1.41 and 6.00 ± 1.00, respectively. It’s possible that the structural and spatial characteristics of Vale Perdido favored the use of this area by the species. The structure of the community of medium-and large-sized terrestrial mammals of PESB is unstructured or in a structuring phase. Possibly, this model was caused by negative historical effects of the occupation and extraction that the region underwent in the 1960s.

    Full Text Available Previously, we demonstrated that the novel lectin Eucheuma serra agglutinin from a marine red alga (ESA induces apoptotic cell death in carcinoma. We now find that ESA induces apoptosis also in the case of sarcoma cells. First, propidium iodide assays with OST cells and LM8 cells showed a decrease in cell viability after addition of ESA. With 50 μg/ml ESA, the viabilities after 24 hours decreased to 54.7 ± 11.4% in the case of OST cells and to 41.7 ± 12.3% for LM8 cells. Second, using fluorescently labeled ESA and flow cytometric and fluorescence microscopic measurements, it could be shown that ESA does not bind to cells that were treated with glycosidases, indicating importance of the carbohydrate chains on the surface of the cells for efficient ESA-cell interactions. Third, Span 80 vesicles with surface-bound ESA as active targeting ligand were shown to display sarcoma cell binding activity, leading to apoptosis and complete OST cell death after 48 hours at 2 μg/ml ESA. The findings indicate that Span 80 vesicles with surface-bound ESA are a potentially useful drug delivery system not only for the treatment of carcinoma but also for the treatment of osteosarcoma.

    Full Text Available Lectin sensitivity of the recent pandemic influenza A virus (H1N1-2009 was screened for 12 lectins with various carbohydrate specificity by a neutral red dye uptake assay with MDCK cells. Among them, a high mannose (HM-binding anti-HIV lectin, ESA-2 from the red alga Eucheuma serra, showed the highest inhibition against infection with an EC50 of 12.4 nM. Moreover, ESA-2 exhibited a wide range of antiviral spectrum against various influenza strains with EC50s of pico molar to low nanomolar levels. Besides ESA-2, HM-binding plant lectin ConA, fucose-binding lectins such as fungal AOL from Aspergillus oryzae and AAL from Aleuria aurantia were active against H1N1-2009, but the potency of inhibition was of less magnitude compared with ESA-2. Direct interaction between ESA-2 and a viral envelope glycoprotein, hemagglutinin (HA, was demonstrated by ELISA assay. This interaction was effectively suppressed by glycoproteins bearing HM-glycans, indicating that ESA-2 binds to the HA of influenza virus through HM-glycans. Upon treatment with ESA-2, no viral antigens were detected in the host cells, indicating that ESA-2 inhibited the initial steps of virus entry into the cells. ESA-2 would thus be useful as a novel microbicide to prevent penetration of viruses such as HIV and influenza viruses to the host cells.

    Full Text Available Tourmalines of intermediate schorl-dravite composition occur in iron formation (including metachert and tourmalinites, metasediments, calc-silicate and metabasic/intermediate rocks of the Morro da Pedra Preta Formation, a volcanic-sedimentary sequence of the Serra do Itaberaba Group (northeast of São Paulo City, southeastern Brazil. The Morro da Pedra Preta Formation is crosscut by quartz veins that contain both intermediate schorl-dravite and an alkali-deficient, Cr-(V-bearing tourmaline, in which the occupancy of the X-site is ϑ0.51Ca0.33Na0.15, characterizing it as intermediate to foitite and magnesiofoitite end-members. Mg# values for this tourmaline are higher than those for intermediate schorl-dravite. Raman spectroscopy also confirms the presence of two groups of tourmalines. Stable isotope data indicate sediment waters as fluid sources, rather than fluids from magmatic/post-magmatic sources. Delta18O compositions for tourmalines, host metachert, and quartz veins are similar, showing that fluid equilibration occurred during crystallization of both quartz and tourmaline. Syngenetic, intermediate schorl-dravite tourmalines were formed under submarine, sedimentary-exhalative conditions; amphibolite-grade metamorphism did not strongly affect their compositions. Younger tourmalines of compositions intermediate to foitite and magnesiofoitite reflect the composition of the host rocks of quartz veins, due to fluid percolation along faults and fractures that caused leaching of Cr (and V and the crystallization of these alkali-deficient, Cr-(V-bearing tourmalines.

    Full Text Available O artigo aborda o conflito em torno do comércio realizado por indígenas Kaingang em um município turístico da Serra Gaúcha, sob a luz do processo sócio-histórico de elaboração da identidade emblemática da cidade. A despeito do poder público e de outros segmentos sociais locais confrontarem as atividades mercadológicas dos índios com a justificativa de uma necessária regulação comercial, advoga-se aqui que o embate encontra explicação mais profunda no choque que estabelece com uma identidade citadina representativa, centrada na ideia de uma mescla étnica bem-sucedida, propiciada pela colonização alemã e italiana. O abalo identitário ocorre não apenas pela presença dos indígenas na cidade, mas também pela forma de comércio por eles realizada, classificada enquanto ambulante, bem como pelo tipo de produto vendido, caracterizado como industrializado de origem asiática. A partir dessa discussão central, outros contrastes identitários históricos e/ou contemporâneos são problematizados.

    Full Text Available Muitos, estudos ja foram conduzido com queijos artesanais nas regiões produtoras dc estado de Minas Gerais, e particularmente na Serra da Canastra, porém, os mesmos ainda são muito carentes de estudos que permitam melhoria da qualidade, padronização entre produtores e ao longo das variações sazonais que acontecem. Este trabalho estudou a composição do queijo Canastra a partir da escolha de uma quedaria típica e tradicional da região e em cada uma das quatro estações do ano. Poucas diferenças de temperatura e umidade relativa puderam ser verificadas entre as estações que mostra uma descaracterização entre elas. Porém mesmo assim resultaram em diferenças significativas na composição dos queijos, também per causa da sazonalidade da produção do leite e variação no "pingo", e, ainda pela despadronização do leite para fabricação de queijo, mesmo com o processo de fabricação sendo bem padronizado.

  12. The role of viscosity in the emplacement of high-temperature acidic flows of Serra Geral Formation in Torres Syncline (Rio Grande do Sul State, Brazil

    Directory of Open Access Journals (Sweden)

    Matheus Silva Simões

    Full Text Available The acidic flows from Serra Geral Formation in Torres Syncline, Rio Grande do Sul, Brazil, are on the top of a volcanic sequence composed by a complex facies association of compound, simple and rubbly pahoehoebasic flows, acidic lava domes, and tabular acidic lava flows. The origin and emplacement conditions of the acidic volcanic rocks are discussed in this paper based on petrology, on calculated apatite saturation thermometry temperatures, and on estimated viscosity data. The liquidus temperatures for metaluminous rhyodacite to rhyolite samples are about 1,067.5 ± 25ºC in average. The viscosity (η values vary from 105 to 106 Pas for anhydrous conditions, suggesting the emplacement of high-temperature - low-viscosity lava flows and domes. The occurrence of acidic lava domes above simple pahoehoe flows as flow-banded vitrophyres was under low effusion rates, in spite of their high temperature and low viscosities, which are reflected in their small height. The emplacement of lava domes has continued until the eruption of rubbly pahoehoe flows and the geometry of these deposits rugged the relief. Presence of tabular acidic lava flows covering the landscape indicates that it was under high effusion rates conditions and such flows had well-insulated cooled surface crusts. The capacity to attain greater distances and overpass relief obstacles is explained not only by high effusion rates, but also by very low viscosities at the time of emplacement.

    Ecological changes from water resources development projects often affect the epidemiology of water-associated diseases. In order to investigate the occurrence and distribution of freshwater snails of medical and veterinary importance in the area of influence of the Serra da Mesa Hydroelectric a survey has been performed since 1997 and revealed the occurrence of well-established populations of Biomphalaria straminea (Dunker, 1848) in the 8 municipalities surrounding the lake. Areas of epidemiologic risk for schistosomiasis were selected and studies of parasite-mollusc compatibility were undertaken using specimens from 19 populations of B. straminea and 3 strains (CM, EC and PB) originally isolated from B. straminea. Among 1,135 specimens used 15 became infected (infection index of 1.3%) and 8 populations were susceptible to the schistosome strains: B. straminea from Campinorte (Castelão, susceptible to CM and EC strains, and Planeta Agua, EC strain), Colinas (Tocantinzinho river, CM and EC strains), Minaçu (Canabrava river, EC strain), Niquelândia (Codemin, CM and PB strains, and Almas river, CM strain), Uruaçu (touristic area, PB strain) and Santa Rita do Novo Destino (Maranhão river, CM and EC strains). These results, associated with marked social and ecological changes occurred, strongly suggest the possibility of B. straminea coming to act as a vector of schistosomiasis in the studied area.

    Metasiliciclastic rocks predominate in the lower units of the Palaeo-Mesoproterozoic Espinhaço Supergroup, in the southern Serra do Espinhaço, Minas Gerais, Brazil. The lower units also comprise rocks with locally preserved igneous fabrics, but which have very unusual chemistries. These rocks, collectively known as hematitic phyllite, are characterised by abundant fine-grained muscovite, i.e. sericite, and variable amounts of titaniferous hematite, rutile and tourmaline. Currently, the hematitic phyllite has been interpreted as a metamorphosed palaeosol after basaltic rocks and, as such, has been used as a palaeoclimatic indicator. However, the lateritic nature of the hematitic phyllite cannot unambiguously be determined because of the K metasomatism, hematitisation and tourmalinisation recorded in the hematitic phyllite and in the arenaceous country rocks. Here we report the B-isotopic and chemical compositions of tourmaline from the hematitic phyllite. Our δ11B data are in the range between - 15‰ and 4‰. The tourmaline compositions fall along the povondraite-"oxy-dravite" join, which defines a meta-evaporitic tourmaline trend. A meta-evaporitic B source is constrained by the B-isotopic data as non-marine. Our model for the hematitic phyllite suggests that B- and K-rich brines were derived from the metamorphic dewatering of non-marine evaporites. Such brines extensively altered volcanic rocks of basaltic and rhyolitic compositions, leading to tourmaline-bearing, hematite-sericite assemblages of the hematitic phyllite.

    Horses are phylogenetically distant from primates, but considerable behavioral links exist between the two. The sociality of horses, characterized by group stability, is similar to that of primates, but different from that of many other ungulates. Although horses and primates are good models for exploring the evolution of societies in human and non-human animals, fewer studies have been conducted on the social system of horses than primates. Here, we investigated the social system of feral horses, particularly the determinant factors of single-male/multi-male group dichotomy, in light of hypotheses derived from studies of primate societies. Socioecological data from 26 groups comprising 208 feral horses on Serra D'Arga, northern Portugal suggest that these primate-based hypotheses cannot adequately explain the social system of horses. In view of the sympatric existence of multi- and single-male groups, and the frequent intergroup transfers and promiscuous mating of females with males of different groups, male-female relationships of horses appear to differ from those of polygynous primates.

    Full Text Available The ecology of mosquito species (Diptera: Culicidae was studied in areas of the Serra do Mar State Park, State of São Paulo, Brazil. The influence of the lunar cycle and the daily biting rhythms of mosquito populations were analyzed. Systematized biweekly human bait collections were made in a silvatic environment for 24 consecutive months (January 1991 to December 1992. A total of 20,591 specimens of adult mosquitoes belonging to 55 species were collected from 545 catches. Sabethini species were captured exclusively during daylight periods, with the exception of Trichoprosopon digitatum, while members of Anophelinae predominated during nocturnal hours. Members of the subfamily Culicinae that were collected primary during nocturnal periods included Culex nigripalpus, Coquillettidia chrysonotum and Cq. venezuelensis while daytime catches included Psorophora ferox and Ps. albipes. Others members of culicines mosquitoes that were collected during both day and night included: Aedes serratus, Ae. scapularis and Ae. fulvus. Lunar cycles did not appear to influence the daily biting rhythms of most mosquito species in the area, but larger numbers of mosquitoes were collected during the new moon. Ae. scapularis were captured mainly during the full moon.

    The reason for the development of this work is based on knowing many Basic Education's teachers (EB) don't deal concepts related to astronomy and when they do, followed didactic books which contain many conceptual errors, it also know that astronomy is one of the contents that it being taught in the EB and do part of what is proposed by the Education Ministry and Education Department São Paulo State and also, that several researchers point out many mistakes in the teaching of Astronomy. It's purpose of minimizing some deficiencies, which was drawed an University Extension Course for Teachers of Diretoria de Ensino Regional (Mauá, Ribeirão Pires and Rio Grande da Serra) with the following objectives: to raise alternative conceptions; to subsidize teachers by means of lectures, discussions and workshops, and to check the learning after the course. Therefore, sixteen questions were applied before and after the course, so it was established that 100% of the teachers knew the names of the phases of the moon, 97.0% understood that the Solar System is composed by eight planets, 78.1% explained as occured "Lunar Eclipse", "Solar Eclipse" and "Solstice", 72.7% knew to explain the occurrence of the seasons of the year; 64.5% explained the occurrence of the equinox correctly, 89.7% were able to define properly "comet"; 63.6% defined "Asteroid", 54.5% defined "meteor"; 58.1% defined "galaxy", and 42.4% defined "planet".

    The Serra da Providência batholith includes the type area of the homonymous suite, the oldest rapakivi magmatic assemblage in the SW of the Amazonian craton (1.60-1.53 Ga). In the midwest portion of this massif, besides wiborgites/pyterlites and granophyric syenogranites, a leucosyenogranite facies and porphyritic rhyolites constitute new rock varieties recently described in that area. Usbnd Pb LA-MC-ICP-MS zircon ages of 1574 ± 9 Ma and 1604 ± 3 Ma, respectively, were obtained for these new varieties and confirm their link with the Serra da Providência magmatism, whereas the subvolcanic rocks are older than the main rock varieties and were formed in a precursor event. These granitic facies are metaluminous to peraluminous, alkali-calcic, A2-type, ferroan granites. Their FeOt/(FeOt + MgO) ratios vary from 0.83 to 0.98 and suggest that these rocks were crystallized from oxidized-to reduced-A-type magmas, where the leucosyenogranites and granophyric sienogranites tend to be formed under more reduced conditions. They show fractionated REE patterns with very pronounced to weak negative Eu anomalies. The presence of granophyric textures and miarolitic cavities in equigranular syenogranitic facies suggests that these rocks were formed at shallow crustal depths, lower than 3 km. Three samples of leucosyenogranite have silica contents higher than 75% and low K/Rb ratios (negative Eu anomalies a feature not observed in the equigranular gabbronorites. Porphyritic gabbronorites geochemical characteristics are similar to calc-alkaline basalts, whereas equigranular gabbronorites are similar to continental basalts. Petrographic, geochemical, and geological data of the felsic facies and the presence of associated mafic rocks corroborate the bimodal and post-collisional character of this magmatism. The occurrence of porphyritic rhyolites associated with shallow level plutonic granites in the Serra da Providência batholith reinforces the similarities between the Rondonian

    The Rio dos Sinos Watershed area is located at the Middle-West region of the Rio Grande do Sul State, Southern Brazil, along thirty two municipalities and affecting 1.5 million inhabitants and many important industrial centers. Three main aquifers are recognized in the study area: the unconfined-fractured Serra Geral Aquifer System, the porous Guarani Aquifer System, and the Permian Aquitard. This study aims to understand groundwater, surface water and human activity interactions in the Rio dos Sinos Watershed, evaluating the application of stable lead isotopic ratios analyzed for this propose. Thirty six groundwater samples, 8 surface water samples and 5 liquid effluents of tanneries and landfills samples were measured using a Thermal Ionization Mass Spectrometer Thermo-Finnigan and a Neptune Multi-Collector Inductively Coupled Plasma Mass Spectrometer. Groundwater isotopic ratios have a wider range compared to the surface water, with less radiogenic averages (208)Pb/(204)Pb = 38.1837 vs 38.4050 (standard deviation = 0.2921 vs 0.1343) and (206)Pb/(204)Pb = 18.2947 vs 18.4766 (standard deviation = 0.2215 vs 0.1059), respectively. Industrial liquid effluents (tanneries and industrial landfill) have averages (208)Pb/(204)Pb = 38.1956 and (206)Pb/(204)Pb = 18.3169, distinct from effluent samples of domestic sanitary landfill (averages (208)Pb/(204)Pb = 38.2353 and (206)Pb/(204)Pb = 18.6607). Hierarchical cluster analysis led to distinguish six groups of groundwater, representing the three aquifers that occur in the area, two clusters suggesting groundwater mixtures and one demonstrating a highly contaminated groundwater. By analyzing the cluster results and wells' stratigraphic profiles it was possible to distinguish the different aquifers in the area. The Serra Geral Aquifer System has (206)Pb/(204)Pb ratios between 18.4718 and 18.7089; (207)Pb/(204)Pb between 15.6692 and 15.6777; (208)Pb/(204)Pb between 38.6826 and 38.7616; (207)Pb/(206)Pb between 0

    Full Text Available A influência do desmatamento da Mata Atlântica sobre o microclima da Serra da Mantiqueira ainda não é totalmente compreendida. Para conhecer as consequências do desmatamento sobre o clima serrano é necessário realizar estudos sobre o balanço de radiação na superfície. A falta de dados possibilita conjugar imagens de satélite com dados meteorológicos em um Sistema de Informação Geográfica na determinação do balanço de radiação. O presente estudo teve por objetivo avaliar o modelo MTCLIM em dias de céu claro ou nublado para simular o balanço de radiação na Serra da Mantiqueira, divisa entre os estados de São Paulo, Minas Gerais e Rio de Janeiro, Brasil. Imagens diárias, semanais e dezesseis dias do sensor MODIS disponíveis em 2003 foram utilizadas em rotinas específicas do MTCLIM. Alvos específicos foram selecionados para avaliar o comportamento do balanço de radiação. Observou-se que o balanço de radiação acompanhou a topografia local e é influenciado pelo tipo de uso da terra. Conclui-se que a temperatura da superfície contribui para aumentar a temperatura do ar implicando em diminuição do balanço de radiação sobre pastagem. O modelo MTCLIM demonstrou boa correlação para a temperatura do ar (R² = 0,82 e para a radiação solar global (R² = 0,71.The influence of deforestation of the Atlantic Forest on the microclimate of the mountain Mantiqueira is not yet fully understood. To understand the consequences of deforestation on the highland climate research is needed about the surface radiation balance. The lack of data allows combining satellite images with meteorological data in a Geographic Information System in determining the radiation balance. The study aimed to evaluate the MTCLIM model in cloudless days or cloudy sky and simulate the radiation balance in the Mantiqueira mountain, between São Paulo, Minas Gerais and Rio de Janeiro, Brazil.

    Full Text Available The reproductive biology of 13 monoecious species of Begonia L. (Begoniaceae that occur in the Serra do Mar State Park, São Paulo, Brazil, was investigated. These species flower annually and present flowers with mostly white tepals, light and sweet odour, pollen as a reward but no nectar, numerous yellow stamens, and coiled yellow styles. Anthesis is diurnal and floral duration is long (6 - 15 days. The unusual appearance of pistillate flowers of these species supports the view that they are intersexual mimics of the staminate flowers. Despite consistently high levels of fruit-set, none of the 11 species tested proved to be apomictic. In contrast to earlier reports of self-compatibility in Begonia, self-pollinations of B. integerrima and B. itatinensis produced no fruits or seeds, and the complete absence of pollen tubes in the styles of self-pollinated flowers of B. integerrima suggests that the species is genetically self-incompatible. Flowers pollinated under natural conditions showed many pollen tubes that reached ovules, suggesting that adequate numbers of compatible pollen grains had been transported by pollinators. The principal pollinators were small bees of the Apidae and Halictidae. Ten species of bees were observed to visit eight species of Begonia, and pollen collection occurred by means of vibration, except for Trigona spinipes. Visits to rewarding staminate flowers were significantly more frequent than visits to unrewarding pistillate flowers. Duration of visits to pistillate flowers also was significantly shorter than the duration of visits to staminate flowers. We conclude that visits to pistillate flowers occur by mistake but with sufficient frequency to allow for successful reproduction in natural populations of these species.

O tema central desse exercício foi o desenvolvimento de uma estratégia para implantação de uma infra-estrutura verde para a bacia do córrego Poá, localizada no município de Taboão da Serra, em São Paulo, que hoje se encontra em uma área intensamente transformada, densamente construída e poluída. O trabalho foi elaborado em dois momentos, abrangendo uma proposta para toda a bacia e outra para um recorte escolhido dessa bacia. As propostas surgiram do cruzamento entre os mapas elaborados sobre os aspectos biofísicos e urbanos locais, a revisão teórica e as análises realizadas em visitas a campo. Foram sugeridas novas formas de planejar-se a paisagem a partir da qualificação e articulação dos espaços abertos vegetados e da criação de formas de circulação para as pessoas, a fauna local e as águas. Contudo, para o sucesso da aplicação desse conceito é necessária a reunião de esforços coordenados e multidisciplinares, envolvendo instituições de pesquisa, comunidade, autoridades e lideranças locais.

  14. Aspects of a conceptual groundwater flow model of the Serra Geral basalt aquifer (Sao Paulo, Brazil) from physical and structural geology data

    A preliminary conceptual model of groundwater flow was developed for the Serra Geral fractured basalt aquifer in order to assess the recharge to the underlying sandstone Guarani Aquifer System, one of the main aquifer systems in Brazil, which supplies water to millions of people. Detailed geological investigations included macroscopic description of the basalt flow units and the underlying sandstone. Petrographic and chemical analyzes were conducted on rock samples from outcrops and from five drilled boreholes. Detailed fracture surveys were accomplished at outcrops to characterize fracture sets and their potential to transmit water in the current tectonic context. Four basalt flows were identified in the Ribeirao Preto area and were named B1, B2, B3 and B4 (from oldest to youngest). The cooling process in flow B3 led to the generation of large sub-horizontal fractures at the contacts B2/B3 and B3-C/B3-E, which are the most transmissive structures. Groundwater flow in the basalt appears to be of the stratabound type because fractures, in general, do not propagate through the basalt vesicular layers, which behave as a regional hydraulic barrier for the vertical groundwater flow. However, it is proposed that the localized, continuous and closely spaced subvertical tectonic fractures, the only features that have the potential to crosscut the vesicular layers and the intertrappe sediments, can vertically connect the sub-horizontal transmissive fractures. Weathering and water seepage, observed in rock exposures, indicate that subvertical NE-trending fractures would be the most transmissive in the Ribeirao Preto area.

    Full Text Available Entre os fatores que interferem na composição e na qualidade do vinho, destaca-se a safra vitícola, com suas variações climáticas. Com este objetivo, avaliou-se o efeito das safras de 1999, 2000 e 2001 na composição da uva, do mosto e do vinho Isabel da Serra Gaúcha. Nesse sentido, foram selecionados vinte e dois produtores de uva Isabel de onze municípios dessa região. Por ocasião da maturação, para as avaliações da uva e do mosto e a elaboração das microvinificações, foram colhidos 60kg de uva de cada viticultor. A safra vitícola interferiu significativamente no peso do cacho e da baga, mas não alterou a relação peso da ráquis/peso do cacho. No mosto, observaram-se diferenças em todas as variáveis, exceto para a relação degreesBrix/acidez total. No vinho, teve efeito na maior parte das variáveis avaliadas, com exceção aos cátions K, Mn, Cu e Rb. Em geral, a safra de 1999 foi a melhor, pois apresentou parâmetros mais adequados de acidez total, extrato seco, extrato seco reduzido, alcalinidade das cinzas, taninos, antocianinas e glicerol, variáveis essas que determinam a estrutura e a cor dos vinhos, importantes fatores para sua qualidade.

    Full Text Available As políticas de conservação da natureza em diversos paises estão cada vez mais ligadas à tomada de decisões ecológicas globais. Exemplos destas ligações variam entre a definição de prioridades e objetivos das políticas, à ação de ONG's ambientalistas internacionais, à existência de fundos e programas globais para o meio ambiente e o desenvolvimento sustentável, até as novas oportunidades econômicas representadas pelos mercados emergentes para serviços ecológicos globais e ''commodities ambientais''. Estas políticas freqüentemente conflitam com os direitos e as necessidades de diferentes populações locais, pois a implementação de áreas protegidas que excluem o homem recebe prioridade com respeito a outros modelos de conservação e uso sustentável da biodiversidade. O Brasil não faz exceção a esta regra. Hoje as políticas de conservação da natureza estão entrando em conflito direto com as políticas de preservação do direito à diferença cultural dos povos indígenas. Isto acontece a diversos níveis e em vários contextos locais diferenciados, desde a região Atlântica até a Amazônia e o Escudo das Guianas. A existência de fundos globais e suas prioridades podem contribuir para explicar estes conflitos, pois a ligação ecológica global contribui para redefinir as relações políticas nacionais e locais. O caso do Parque Nacional do Monte Roraima na Terra Indígena Raposa-Serra do Sol ilustra como modelos de conservação baseados na exclusão do homem, concebidos e implementados de cima para baixo, acirram conflitos preexistentes, políticos e sobre o direito à terra. Abordado através de um angulo diferente, este caso também aponta um possível caminho para soluções viáveis.

    is study was conducted in an area of 14 km in length oriented in the NNE direction by 7.3 km wide, covering the totality of the Serra do Carambei Granite and adjacent units. Located in the northern region of the Alagados dam, Parana State, this granite contains relatively high concentrations of K, eU and eTh, known since the 1970s through airborne and terrestrial gamma-ray spectrometry surveys. Recent radiochemical tests conducted on 61 samples of geological materials such as rocks (17 samples) and material of the weathering mantle and alluvial deposits (44 samples), confirmed the occurrence of radioactive anomalies in this granite, especially in thorium and uranium. The contents of K, eU and eTh obtained in gamma-ray spectrometry survey and radiochemical tests, converted to annual radiation dose (ARD), allowed to evaluate the intensity of natural radiation, whose levels relatively high in certain regions of the study area, can offer hazard to the local populations. The analysis and interpretation of data, as well the preparation of contour maps of K, eU and eTh were fundamental to understand the behavior and mobility of radionuclides in different environmental compartments of the area.

    Known oviposition attractants or stimulants were compared, singly and in combination, using inexpensive autocidal ovitraps designed to trap emerging adults, in a rural area of Timor-Leste during the dry season. In this area, the dengue vector Aedes albopictus (Stegomyia albopicta) Skuse (Diptera: Culicidae) was abundant, but Aedes aegypti (Stegomyia aegypti) L. was not detected. The attractants were: (a) a compound found in Aedes eggs (dodecanoic acid); (b) components of nitrogen, phosphorous and potassium-based (NPK) fertilizer, and (c) infusions of discarded cigarette butts. A solution of ammonium phosphate and potassium nitrate was significantly more attractive to gravid Ae. albopictus than water only. Dodecanoic acid and cigarette butt infusions were not significantly more attractive than the control; however, they attracted various other Diptera and many non-culicid larvae developed in ovitraps in which these substances were used; thus, the presence of eggs or larvae of other species may have deterred Aedes oviposition. Significantly more Aedes eggs were found in ovitraps under vegetation than in ovitraps placed inside houses or against external walls. Clear-sided ovitraps in which black mesh was placed over a black ring floating on the water surface collected significantly fewer eggs than black ovitraps with identically placed mesh and rings.

    Full Text Available A new species of Plebeia, the second largest genus of stingless bees in the Neotropical region, is described from eastern Brazil. Plebeia grapiuna sp. nov., known only from the lowland forests of southern Bahia, is most similar to P. lucii Moure, a species recently described from Minas Gerais. The lack of yellow marks and the smoother integument of the frons and mesoscutum in P. grapiuna sp. nov. distinguish them. Main features of the nesting habits of the new species are described and illustrated.Uma nova espécie de Plebeia, o segundo maior gênero de meliponíneos na região Neotropical, é descrita do leste do Brasil. Plebeia grapiuna sp. nov., conhecida apenas das florestas de terras baixas do sul da Bahia, é semelhante a P. lucii Moure, uma espécie recentemente descrita de Minas Gerais. A ausência de manchas amarelas e o integumento menos rugoso da fronte e do mesoscuto em P. grapiuna sp. nov. distinguem as duas espécies. Características principais do hábito de nidificação da nova espécie são descritas e ilustradas.

    Full Text Available The study of the physical geology and geochemistry of the basalts of Ribeirão Preto was part of a hydrogeologicalresearch that aimed at investigating the recharge of the Guarani Aquifer System (SAG through the basalts of the SerraGeral Aquifer (ASG, a project shortly named FRATASG. In addition to hydrogeological methods, the research demandeda detailed geological investigation, which is essential for the elaboration of conceptual models of groundwater circulationin complex aquifers, as is the case of the fractured basalts of the ASG. Thus, the study encompassed field work for thedescription of the macroscopic aspects and relationships among the basalts and the underlying sandstones, as well as, rocksampling and petrographic and chemical analysis. Furthermore, the use of lithologic logs of five wells drilled in FRATASG project was essential for the establishment of the subsurface basalt stratigraphy. The study concluded that, in Bonfim Paulista region,there are four basalt floods, namely B1, B2, B3 and B4. The B4 occurrence is very restricted as it was largely eroded. B1 and B2average thicknesses are 45 and 60 m, respectively. All four basalts are of sheet-like lobe types and were probably emplaced by inflation,B1 being the one that presents more evidence in that respect. B1 presents a thick vesicular top and, as well as B2, can show more thanone vesicular layer at the top. Columnar joints were observed in B2 and B3 and are more remarkable in B3, where a lower colonnadetier (B3-C is overlain by an entablature layer (B3-E. B3 is the thickest flow (75 to 105 m and contains irregular and roughly roundpatches of hydraulic breccia in B3-C or along sub-horizontal fractures that allow the circulation of fluids (groundwater at the present. The chemical composition of B3 is homogeneous and very different from B1 and B2 with regard to several oxides (Al2O3, P2O5, Fe2O3, TiO2 e MgO and trace elements (Ni, Zn, Cu, Y. B1 is very different from B2 with regard

    Full Text Available OBJETIVO: Estabelecer a influência exercida por três diferentes biótopos em áreas do Parque Nacional da Serra da Bocaina (PNSB sobre a fauna local de mosquitos. MÉTODOS: Foram realizadas capturas mensais em ambiente silvestre e domiciliar, em isca humana, durante três diferentes períodos do dia, pelo período de 24 meses consecutivos, de janeiro de 1991 a dezembro de 1992. RESULTADOS: Foram capturados 11.808 espécimes adultos, pertencentes a 28 espécies. Ru. reversa e An. cruzii foram predominantes, respectivamente 52,5% e 17,9% do total de mosquitos. Ru. reversa representou 59,4% do total de espécimes no ambiente de mata fechada, seguida por Ru. frontosa com 10,5% e An. cruzii com 9,9%. No ambiente formado por campos de altitude e matas de galeria, o An. cruzii predominou com 48,1%, seguido por Ru. reversa com 28,1%. No ambiente modificado pelo homem, o An. cruzii predominou com 73,7% dos espécimes. Coquillettidia chrysonotum foi a única que se apresentou preferencialmente nesse biótopo: 14,9% no intra, 19,4% no peri e 65,7% no extradomicílio. An. cruzii e Ru. reversa foram constantes em todos os ambientes ao longo do ano. CONCLUSÕES: Com exceção de Cq. chrysonotum, com preferência pelo ambiente modificado pelo homem, os mosquitos apresentam hábitos assinantrópicos no PNSB. An. cruzii, embora assinantrópico, se aproxima e adentra o domicílio para realizar a hematofagia. A presença do Ae. serratus no extra e peridomicílio reforça a importância epidemiológica como vetora potencial de arboviroses. Os Sabethini apresentaram-se exclusivamente silvestres.

Um dos escorregamentos fica situado em área de floresta preservada e o outro em uma área de vegetação secundária. Para avaliar a distribuição de comunidade de palmeiras, foram alocadas parcelas circulares de 100m2 nas bordas das cicatrizes dos deslizamentos e no interior da vegetação adjacente em três altitudes (baixo, meio e topo. As palmeiras classificadas em três estádios ontogênicos (plântulas, jovens e adultos estavam representadas por cinco espécies na área preservada (espécies de dossel superior: Attalea dubia e Euterpe edulis e espécies de sub-bosque: Geonoma gamiova, G. pohliana e G. schottiana e quatro espécies na área de floresta secundária (as mesmas espécies, exceto G. pohliana. A perturbação causada pelos escorregamentos na comunidade de palmeiras se deu de forma que as espécies como E. edulis e G. schottiana na fase jovem foram estimuladas pelo aumento de luminosidade provocado pelos deslizamentos, enquanto que a espécie G. gamiova diminuiu drasticamente nestas condições em todas as fases de desenvolvimento. O padrão de regeneração observado indica que espécies de palmeiras dos diferentes estratos da floresta respondem de maneira diferente a este tipo de perturbação ambiental.

    In the hinterland of Rio de Janeiro city the rivers Guapiaçu, Macacu and Iconha originate in the Serra dos Órgãos mountain range and drain into the Atlantic Ocean. Since their channelization in the 1950s, higher flow velocities caused an incision of the rivers into the valley fills. These circumstances provide the possibility to study the alluvial deposits along the streams during low water level and allow conclusions on palaeoenvironmental change and landscape history. Sedimentological investigations of 13 exposures as well as AMS 14C measurements were carried out to investigate sediment properties and reconstruct the sedimentation history within the floodplains. These results enable to distinguish three different facies units. A late Pleistocene Unit I can be detected at the base of the observed exposures and consists of clast-supported fine to coarse gravels. It can be assumed that the gravel bodies were formed by a climatically induced erosional-depositional cycle within a braided river system. The gravels are overlaid by Unit II, a grayish to bluish loam mainly of mid-Holocene age. During generally drier climates these loams have been deposited during high water stages or flooding events as a splay facies proximal to the rivers. A reduced flow competence and relatively stable morphodynamic conditions are assumed for that period. Unit III accumulated in the late Holocene typically consists of several meters of planar or cross bedded sands to fine gravels, interfingered by loamy inclusions, buried peat bogs and organic debris. Fining-upward sequences can be frequently studied within Unit III which were completed by loamy sediments in the uppermost parts of the exposures. The increased flow competence from Unit II to Unit III seems to be a fluvial response to the increased humidity of the late Holocene as well as the enhancement of El Niño-Southern Oscillation (ENSO). Heavy rainfall likely caused higher sediment supply from the steep slopes as well as a

    The most recent and significant transformations of European landscapes have occurred as a consequence of a series of diffused, varied and often connected phenomena: urban growth and sprawl, agricultural intensification in the most suitable areas and agricultural abandonment in marginal areas. These phenomena can affect dramatically ecosystems' structure and functioning, since certain modifications cause landscape fragmentation while others tend to increase homogeneity. Thus, a thorough comprehension of the evolution trends of landscapes, in particular those linked to urban-rural relations, is crucial for a sustainable landscape planning. In this framework, the main objectives of the present paper are: (a) to investigate Land Use/Land Cover (LULC) transformations and dynamics that occurred over the period 1955-2006 in the municipality of Serra San Bruno (Calabria, Italy), an area particularly representative of the Mediterranean mountainous landscape; (b) to compare the settlement growth with the urban planning tools in charge in the study area; (c) to examine the relationship between urban-rural gradient, landscape metrics, demographic and physical variables; (d) to investigate the evolution of urban-rural gradient composition and configuration along significant axes of landscape changes. Data with a high level of detail (minimum mapping unit 0.2 ha) were obtained through the digitisation of historical aerial photographs and digital orthophotos identifying LULC classes according to the Corine Land Cover legend. The investigated period was divided into four significant time intervals, which were specifically analysed to detect LULC changes. Differently from previous studies, in the present research the spatio-temporal analysis of urban-rural gradient was performed through three subsequent steps: (1) kernel density analysis of settlements; (2) analysis of landscape structure by means of metrics calculated using a moving window method; (3) analysis of composition and

    Full Text Available Nos últimos anos, grandes perdas de colônias de abelhas melíferas vêm sendo registradas em várias regiões do mundo. Contudo, os motivos desse acontecimento permanecem obscuros. O ácaro ectoparasita Varroa destructor Anderson e Trueman (Acari: Varroidae pode ser um dos responsáveis por esse fato, principalmente como vetor de vírus. Neste estudo, avaliaram-se as taxas de infestação (TIs do ácaro V. destructor em abelhas africanizadas Apis mellifera L. (Hymenoptera: Apidae e correlacionaram-se os dados com as médias de temperatura de 16 municípios das regiões do Vale do Paraíba e da Serra da Mantiqueira (São Paulo, Brasil, onde a apicultura comercial atua de maneira significativa. Em cada município, um apiário comercial foi selecionado para coleta de amostras de três colônias populosas (padrão Langstroth, totalizando 48 colônias amostradas. Aproximadamente 300 abelhas adultas localizadas na área de cria foram coletadas em cada colônia. As TIs variaram de 0.0 a 5.5%, níveis considerados baixos para causar danos significativos às colônias. As TIs mais baixas foram encontradas em municípios com clima mais ameno durante a estação avaliada (verão. Adicionalmente, cofatores como variações na disponibilidade de alimento entre os municípios e a variabilidade genética das abelhas podem interagir na interação entre parasita e hospedeiro. A variação nas TIs entre os municípios indica que, mesmo presente, a tolerância das abelhas africanizadas ao varroa pode variar drasticamente em uma pequena região, devido à dinâmica multifatorial de infestação do ácaro.

    Full Text Available Ischnocnema (Brachycephalidae includes many species that are important members of the leaf litter frog communities in the Atlantic Rainforest of Brazil. Ischnocnema parva (Girard, 1853 is endemic to the Atlantic Rainforest biome and is restricted to the forests of southeastern Brazil. Currently, the available information about the ecology of I. parva is scarce. We studied the diet, the habitat use, reproduction and density of I. parva in an area of Atlantic Rainforest at the Concórdia mountain range, Rio de Janeiro. Individuals of I. parva were captured in April 2005 using different sampling methods: time constrained search (transects, plots of 5 x 5 m (25 m² on the litter, and pitfall traps with drift fences. We found 240 frogs; 35 females and 205 males. Females (mean SVL = 19.1 mm were significantly larger (F1,238 = 143.016, R² = 0.375, p < 0.001 than males (13.2 mm. The species preyed mainly on arthropods, with ants and isopods being the most important items, both showing high values of importance index (Ix = 50.0 and 26.7, respectively. Ischnocnema parva is a terrestrial species whose preferential microhabitat at the Serra da Concórdia was the litter of the forest floor (78.7%. The activity was predominantly crepuscular-nocturnal and the estimated density of I. parva was 24.9 ind/100 m². For the eight ovigerous females captured, the mean number of mature oocytes per female was 25 (range: 22-30 and the oocyte mean diameter was 1.11 mm (N = 40 oocytes. Oocyte number increased with female body size (R² = 0.504, F1,6 = 6.107, p < 0.05, N = 8, indicating that as females increase in size they produce larger clutches. Some ecological aspects such as diet and microhabitat use were similar to that observed for an insular population of I. parva, whereas reproductive traits differed. Thus, long term studies are necessary to understand the extent to which these differences are explained by environmental factors.

    Full Text Available Com o aumento da população nos últimos anos, a indústria de modo geral tem se adequado à demanda resultante. A indústria do processo de recauchutagem de pneus gera resíduos que em sua maioria têm sido descartados sem nenhum controle. Este fato contribui para aumentar a poluição ambiental e favorecer a proliferação de vetores nocivos àsaúde. Visando encontrar uma aplicação para esse tipo de resíduo, neste trabalho serão apresentados resultados experimentais de blocos intertravados para pavimentos de concreto, com traços adicionados de resíduos de pneus. Foram confeccionados blocos intertravados em que se determinou, por meio de ensaios laboratoriais, a necessidade de se fixar o traço que desse maior retorno quanto às características analisadas. Verificaram-se quatro tipos de traços de concreto com resíduos de pneus. Procedeu-se aos ensaios de resistência mecânicaà compressão, absorção de água e resistência ao impacto. Pelos resultados preliminares obtidos, verificou-se que são satisfatórios, confirmando-se a possibilidade de aplicação desse tipo de bloco intertravado em ambientes com solicitações baixas, o que traria, além da economia das fontes naturais de agregados, benefícios ecológicos pela reutilização dos resíduos da recauchutagem de pneus.With the population growth in recent years, industry in general has ajusted itself to resulting demand. the industry of tire retreading generates residues that have been discarded without any control. this adds to environmental pollution and promotes the proliferation of vectors harmful to health. aiming to find an application for this type of residues, this study presents experimental results to interlocking concrete block pavements, with addition of residuestires. interlocking blocks were built up and we determined, through laboratory tests, the need to set the mark that provide greater return regarding analyzed characteristics. there are four types of dosage

    Full Text Available O presente texto analisa a relação da política macroeconômica e o desenvolvimento econômico com seus condicionantes políticos, desde 1995 até os dias atuais (governos FHC, Lula e Dilma, por meio da abordagem da economia política, aplicando os conceitos de dominância financeira, dependência e bloco no poder. Ao adotar tal método, partiu-se do pressuposto de que a adoção de determinada política econômica é decorrência: i dos condicionantes externos, atrelados, no caso brasileiro, à sua condição periférica; ii dos condicionantes internos associados à interação e conflitos de interesses econômicos e políticos das frações de classe no bloco no poder e em seus desenlaces no Estado. O texto conclui que as mudanças recentes no bloco no poder, entre o final do governo Lula e início do governo Dilma, conferiram maior autonomia ao Estado, especialmente diante da fração bancário-financeira, até então hegemônica, o que abre espaço para a retomada das políticas de desenvolvimento.This paper analyzes the relationship between macroeconomic policy and economic development and the political constraints of that relationship from 1995 until present day ( Cardoso, Lula and Dilma Rousseff. This analysis relies on the political economy approach, applying the concepts of financial domination, dependence and power blocs. By virute of this method, we assume that the adoption of certain economic policy is the result of: i the external constraints (which, in Brazil, are coupled with the country's status as a peripheral and dependent economy and ii the constraints associated with the internal interaction and conflicts of economic and political interests of class fractions in the power bloc and its influence on the State. The paper concludes that recent changes to the power bloc between the end of the Lula administration and the beginning of the Rousseff administration gave the government greater autonomy, particularly in relation to the
