Aplicação de técnicas de geoprocessamento para a avaliação da expansão urbana no municípo de Duque de Caxias (RJ) como subsídio ao monitoramento de dutos: trecho da faixa de dutos Rio de Janeiro - Belo Horizonte

Different forms of human pressure may occur in the pipeline ranges, due to the large extensions and various configurations of land use, which can pass through the pipelines. Due to the dynamics of these pressures, it is necessary to monitor temporal changes of land use and cover the surface. Under this theme, appears as extremely important to use products and techniques of remote sensing, as they allow the identification of objects of the land surface that may compromise the security and monitoring of the pipeline, and allows the extraction of information conditions on land use at different periods of time. Based on the above, this paper aims to examine in a temporal approach, the process of urban expansion in the municipality of Duque de Caxias, located on the outskirts of the metropolitan area of the state of Rio de Janeiro, as well as settlement patterns characteristic of areas that the changes occurred in the period 1987 to 2010. We used the technique of visual analysis to perform the change detection and the technique of image classification, aimed at monitoring human pressure over a stretch of track pipeline Rio de Janeiro - Belo Horizonte, located in the state of Rio de Janeiro. The stages of work involved the characterization of the study area, urban sprawl and the existing settlement patterns, through the analysis of bibliographic data. The processing of Landsat 5 images and the application of the technique of change detection were performed in three scenes for the years 1987, 1998 and 2010, while the classification process was performed on the image RapidEye for the year 2010. Can be noted an increase in urban area of approximately 22.38% and the change of land cover from natural to built. This growth is concentrated outside to the area of direct influence of the duct, occurring in the area of indirect influence of the enterprise. Regarding the settlement patterns of growth areas, it was observed that these are predominantly

Análise das ocorrências de escorregamento por meio de imagens Geoeye em trecho da faixa de dutos Rio de Janeiro - Belo Horizonte

The analysis of natural processes, such as landslides, has a great importance for the prevention of accidents in pipelines, since it might compromise its security, with serious social and environmental implications. Considering the large territorial dimensions that pipelines can reach, remote sensing tools have great applicability for data acquisition, allowing the analysis of large areas in regular time periods. This study aims to analyze the relations between the occurrence of landslides and its natural conditionings, on a stretch of the ORBEL pipeline, in the municipalities of Duque de Caxias, Nova Iguaçu and Belford Roxo – Rio de Janeiro. GeoEye sensor system images were used with spatial resolution of 0.5 m, from November/2009, January/2010 and March/2010, that are months of summer rains. The work involved the characterization of the study area and existing landslides, through bibliographic data collection; the application of visual analysis techniques for the extraction of landslide scars and fractures; preparation of maps for the landslide constraints and preparation of the susceptibility map. In the images from November only three landslide scars were extracted, while in January there were 166 and 111 in March. Difficulties were found with the shading in the images. From the relations among landslide scars, lithological units, relief systems, slope, downhill profile and the generated map of landslide susceptibility, presented in 1:70,000 scale, it was possible to conclude that slope is the main determinant of the process, allied secondarily to downhill profile, relief systems and lithology

As técnicas de agricultura tradicional em combinação com propostas e práticas de sistemas agroflorestais: consensos possíveis ao desenvolvimento sustentável da Reserva de Desenvolvimento Sustentável Quilombos de Barra do Turvo, Vale do Ribeira (SP)

O presente estudo teve como objetivo analisar questões sociais e econômicas do cotidiano de quatro comunidades quilombola (Cedro, Pedra Preta, Ribeirão Grande e Terra Seca) residentes da Reserva de Desenvolvimento Sustentável Quilombos de Barra do Turvo (Vale do Ribeira/SP), e levantar o debate acerca da questão da luta pelo reconhecimento da posse da terra frente à saída dos mais jovens da comunidade para as grandes cidades. Através dos dados coletados por meio de levantamento bibliográfico a respeito do tema e entrevistas semiestruturadas com representantes das famílias das quatro comunidades, foi possível discorrer a respeito da problemática da saída dos jovens, que afeta diretamente o futuro dessas comunidades tradicionais, bem como a sugestão de alternativas que visando geração de renda para essas famílias e a inserção e o futuro estabelecimento desses jovens no cotidiano das comunidades. Os resultados deste trabalho mostram que esses quilombolas, bem como seus antepassados, formam comunidades essencialmente rurais e agrícolas, com dinâmica fortemente ligada ao meio natural circundante. Quanto às suas práticas agrícolas, as famílias se dividem em dois grupos: os praticantes da agricultura tradicional, também chamada de “coivara”, e a agroecologia, com Sistemas Agroflorestais bem estabelecidos, onde os agricultores são organizados através de uma cooperativa agroflorestal. Essa divisão agrícola, como mostrado na pesquisa, tem reflexo direto na organização social e econômica das comunidades, bem como no processo de preservação do patrimônio cultural desses grupos. A pesquisa apontou ainda para um grande êxodo dos indivíduos mais jovens das quatro comunidades rumo aos grandes centros urbanos, pela falta de interesse destes na cultural local, ou pela busca por empregos regulares, levantando o questionamento sobre a preservação da cultura e do território quilombola de Barra do Turvo

Uma opção terapêutica para o aumento da faixa de gengiva inserida: o enxerto de tecido conjuntivo livre

Several periodontal procedures have been described in the literature to correct mucogingival alterations or to achieve root coverage. The epithelized free gingival graft is a well established periodontal surgery to increase the width of keratinized gingiva with good stability in the long term follow up. However, this procedure is not commonly used in aesthetic areas since the grafted tissue presents differences of color and contrast. The free connective tissue graft emerges as a viable option to increase attached gingiva in areas where aesthetics results are required. The removal of an epithelized free gingival graft from the hard palate region creates a sore and raw surgical wound that slowly repairs, while the connective tissue graft produces only a line of incision that can be easily sutured promoting a more confortable outcome for the patient. This paper aims to report a case where a free connective tissue graft was used to increase the width of attached gingiva in a tooth with gingival recession. This technique presented satisfactory esthetics results, with a better contrast and color matching with the surrounding tissues.

Spatial distribution of arboviral mosquito vectors (Diptera, Culicidae) in Vale do Ribeira in the South-eastern Brazilian Atlantic Forest

Mosquitoes are vectors of arboviruses that can cause encephalitis and hemorrhagic fevers in humans. Aedes serratus (Theobald), Aedes scapularis (Rondani) and Psorophora ferox (Von Humboldt) are potential vectors of arboviruses and are abundant in Vale do Ribeira, located in the Atlantic Forest in the southeast of the State of Sao Paulo, Brazil. The objective of this study was to predict the spatial distribution of these mosquitoes and estimate the risk of human exposure to mosquito bites. Results of the analyses show that humans are highly exposed to bites in the municipalities of Cananeia, Iguape and Ilha Comprida. In these localities the incidence of Rocio encephalitis was 2% in the 1970s. Furthermore, Ae. serratus, a recently implicated vector of yellow fever virus in the State of Rio Grande do Sul, should be a target for the entomological surveillance in the southeastern Atlantic Forest. Considering the continental dimensions of Brazil and the inherent difficulties in sampling its vast area, the habitat suitability method used in the study can be an important tool for predicting the distribution of vectors of pathogens.

USING THE FRESHWATER BIVALVE Anodontites tenebricosus (LEA, 1834) AS A BIOMONITOR OF METALS IN THE RIBEIRA DE IGUAPE RIVER

USING THE FRESHWATER BIVALVE Anodontites tenebricosus (LEA, 1834) AS A BIOMONITOR OF METALS IN THE RIBEIRA DE IGUAPE RIVER. This study investigated the contamination of the Ribeira de Iguape River - RIR by Cd, Zn, Cr and Pb, using the bivalve Anodontites tenebrieosus as a biomonitor. Metal concentrations in tissue samples were measured by HR-ICPMS. Bivalve tissues exhibited mean levels of 1.00 mu g/g Cd: 152.89 mu g/g Zn; 14.79 mu g/g Cr and 4.40 mu g/g Pb. Lead concentrations were comparable to those reported for moderately contaminated sites. The results showed that Pb is bioavailable to the bivalves, exhibiting high concentrations and exceeding both natural and reference values for human consumption. The freshwater bivalve Anodontites tenebricosus is a suitable biomonitor of contamination by metals.

PRODUÇÃO DE BIOMASSA E COMPOSIÇÃO QUÍMICA DE ADUBOS VERDES CULTIVADOS NO VALE DO RIBEIRA

A contribuição da adubação verde com leguminosas para melhoria do solo e produção agrícola depende em primeiro lugar da produção de biomassa e da sua composição química, que variam em função da espécie, região e estação de cultivo. Objetivo do presente trabalho foi avaliar a composição química da biomassa produzida por adubos verdes no Vale do Ribeira, São Paulo, Brasil. Para tal, foi conduzido um experimento em Pariquera-Açu-SP, no ano agrícola 2006/2007, em blocos casualizados, com quatro tratamentos (três adubos verdes e vegetação espontânea) e cinco repetições. Aos 30, 60, 90 e 120 dias após a semeadura, foram coletadas amostras em 1 m² da parte aérea das plantas e determinada a matéria fresca e seca, bem como a composição da biomassa. Crotalária, guandu e mucuna produziram, em ordem decrescente, as maiores quantidades de biomassa e foram mais eficientes do que a vegetação espontânea. A biomassa produzida pelos adubos verdes apresentou qualidade superior à produzida pela vegetação espontânea. Crotalária e guandu apresentam maior proporção de matéria seca acumulada no caule que possui baixo teor de N, alta relação C/N e L/N, variáveis que tornam a decomposição dos resíduos mais lenta. A análise particionada da matéria seca permite indicação mais precisa da composição química dos resíduos e a previsão da disponibilidade dos nutrientes no solo.

Using AMS combined with mineral shape preferred orientation analysis to understand the emplacement fabrics of the Apiai gabbro-norite (Ribeira Belt, SE Brazil)

The Apiai gabbro-norite is a massive fine-grained Neoproterozoic intrusion emplaced in a core of synformal structure that deforms low-grade marine metasedimentary rocks of the Ribeira Belt of south-eastern Brazil. The lack of visible magmatic layering or any internal fabric has been a major limitation in deciding whether the emplacement occurred before or after the regional folding. To assist in the tectonic interpretations, we combine low-field anisotropy of magnetic susceptibility (AMS) and silicate shape preferred orientation (SPO) to reveal the internal structure of the mafic intrusion. Magnetic data indicate a mean susceptibility of about 10(-2) SI and a mean anisotropy degree (P) of about 1.08, essentially yielded by titanomagnetite. The magnetic and silicate foliations for P >= 1.10 are parallel to each other, while the lineations tend to scatter on the foliation plane, in agreement with the dominant oblate symmetry of the AMS and SPO ellipsoids. For lower P values, the magnetic and silicate fabrics vary from coaxial to oblique, and for P <= 1.05, their shapes and orientations can be quite distinct. The crystal size distribution (CSD) of plagioclase for P > 1.05 is log linear, in agreement with a bulk simple crystallisation history. These results combined show that for a strong SPO, corresponding to a magnetic anisotropy above 1.10, AMS is a reliable indicator of the magmatic fabric. They indicate that the Apiai gabbro-norite consists of sill-like body that was inclined gently to the north by the regional folding.
