The transportation of oil through pipelines raises a concern related to safety and environmental impacts they may cause, especially when exposed to risks that affect their integrity. Among the natural phenomena that can affect the pipelines are erosion and landslides. Considering the large territory involving the pipelines, remote sensing tools have a great applicability for data acquisition. For this, visual analysis techniques were applied to perform change detection in order to monitor erosion features and landslides along a stretch of pipeline Rio de Janeiro – Belo Horizonte, in the state of Rio de Janeiro. The work involved the characterization of the study area as well as the erosion and landslide processes, through bibliographical data. The satellite image processing and the application of change detection techniques were developed in two scenes for the years 2002 and 2010. It was noted a small increase in the number of the identified features, however with regard to their area, a decrease of 21.7% was observed

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

The transportation of oil through polyducts implies a concern related to safety and environmental impacts they may cause, especially when exposed to risks that affect their integrity. Among the various anthropogenic activities included in this scenario, mining can aggravate, increase the risks and degrade the environment. Since these polyducts go through significant extensions, remote sensing has great applicability as a tool for data acquisition. For this, change detection techniques were used to monitor mining activities in a defined study area in the state of Rio de Janeiro, along the duct ORBEL. The characterization of the study area and the mining activities were developed through bibliographical data. The satellite images processing and the application of change detection technique were performed in two scenes for the years 2002 and 2010. The growth in the mining area was about 6.67 times and it was possible to identify types of extraction involved which can represent direct risks to the pipeline

Visando melhoria na qualidade do ensino e da aprendizagem dos alunos, a Secretaria de Educação do Estado de São Paulo elaborou em 2008 um documento para sistematizar um currÃculo único para todas as escolas dos nÃveis de ensino fundamental II e médio, sob sua jurisdição. Assim, objetiva-se com o presente estudo analisar tanto qualitativa quanto quantitativamente a produção acadêmicocientÃfica no campo da Educação FÃsica acerca do CurrÃculo do Estado de São Paulo, a fim de identificar as possÃveis implicações para a prática pedagógica. Para isso, foram analisados artigos publicados em sete periódicos nacionais da área e um banco de teses e dissertações, tendo como recorte temporal o perÃodo de 2008 até 2014. A análise e discussão dos dados se deu, inicialmente, por apresentar os resultados referentes a cada um dos periódicos investigados para, em um segundo momento, compreender de forma qualitativa o panorama geral concernente à produção acadêmica na área da Educação FÃsica sobre a temática do CurrÃculo do Estado de São Paulo. Logo após, os artigos e as teses e dissertações foram organizados de acordo com a classificação de temas investigados proposta por Bracht et al. (2011). Assim, foi possÃvel identificar as possÃveis implicações da produção acadêmico-cientÃfica para a prática pedagógica, sob essa temática. Os resultados indicaram uma baixa quantidade de publicações pautadas no CurrÃculo do Estado de São Paulo para a disciplina de Educação FÃsica. Do total de 593 artigos ou trabalhos monográficos que foram encontrados sobre Educação FÃsica escolar, foram identificados apenas 16 baseados no CurrÃculo do Estado de São Paulo para a disciplina de Educação FÃsica, valor correspondente a 2,69% do total encontrado sobre a temática de Educação FÃsica escolar durante o perÃodo considerado para a pesquisa. Assim, conclui-se que como não é possÃvel afirmar que tudo aquilo...

During 2008D2010, ticks were collected from road-killed wild animals within the Serra dos Orgaos National Park area in the state of Rio de Janeiro, Brazil. In total, 193 tick specimens were collected, including Amblyomma dubitatum Neumann and Amblyomma cajennense (F.) from four Hydrochoerus hydrochaeris (L.), Amblyomma calcaratum Neumann and A. cajennense from four Tamandua tetradactyla (L.), Amblyomma aureolatum (Pallas) and A. cajennense from five Cerdocyon thous L., Amblyomma longirostre (Koch) from one Sphiggurus villosus (Cuvier), Amblyomma varium Koch from three Bradypus variegatus Schinz, and A. cajennense from one Buteogallus meridionalis (Latham). Molecular analyses based on polymerase chain reaction targeting two rickettsial genes (gltA and ompA) on tick DNA extracts showed that 70.6% (12/17) of the A. dubitatum adult ticks, and all Amblyomma sp. nymphal pools collected from capybaras were shown to contain rickettsial DNA, which after DNA sequencing, revealed to be 100% identical to the recently identified Rickettsia sp. strain Pampulha from A. dubitatum ticks collected in the state of Minas Gerais, Brazil. Phylogenetic analysis with concatenated sequences (gltA-ompA) showed that our sequence from A. dubitatum ticks, referred to Rickettsia sp. strain Serra dos Orgaos, segregated under 99% bootstrap support in a same cluster with Old World rickettsiae, namely R. tamurae, R. monacensis, and Rickettsia sp. strain 774e. Because A. dubitatum is known to bite humans, the potential role of Rickettsia sp. strain Serra dos Orgaos as human pathogen must be taken into account, because both R. tamurae and R. monacencis have been reported infecting human beings.

Mannose-binding lectin (MBL) is a protein able to bind to carbohydrate patterns on pathogen membranes; upon MBL binding, its associated serine protease MBL-associated serine protease type 2 (MASP2) is autoactivated, promoting the activation of complement via the lectin pathway. For both MBL2 and MASP2 genes, the frequencies of polymorphisms are extremely variable between different ethnicities, and this aspect has to be carefully considered when performing genetic studies. While polymorphisms in the MBL-encoding gene (MBL2) have been associated, depending upon ethnicity, with several diseases in different populations, little is known about the distribution of MASP2 gene polymorphisms in human populations. The aim of our study was thus to determine the frequencies of MBL2 (exon 1 and promoter) and MASP2 (p.D371Y) polymorphisms in a Brazilian population from Rio de Janeiro. A total of 294 blood donor samples were genotyped for 27 polymorphisms in the MBL2 gene by direct sequencing of a region spanning from the promoter polymorphism H/L rs11003125 to the rs1800451 polymorphism (at codon 57 in the first exon of the gene). Genotyping for MASP2 p.D371Y was carried out using fluorogenic probes. To our knowledge, this is the first study reporting the prevalence of the MASP2 p.D371Y polymorphism in a Brazilian population. The C allele frequency 39% is something intermediate between the reported 14% in Europeans and 90% in Sub-Saharan Africans. MBL2 polymorphisms frequencies were quite comparable to those previously reported for admixed Brazilians. Both MBL2 and MASP2 polymorphisms frequencies reported in our study for the admixed Brazilian population are somehow intermediate between those reported in Europeans and Africans, reflecting the ethnic composition of the southern Brazilian population, estimated to derive from an admixture of Caucasian (31%), African (34%) and Native American (33%) populations. In conclusion, our population genetic study describes the frequencies of MBL2 and MASP2 functional SNPs in a population from Rio de Janeiro, with the aim of adding new information concerning the distribution of these SNPs in a previously unanalysed Brazilian population, thus providing a new genetic tool for the evaluation of the association of MBL2 and MASP2 functional SNPs with diseases in Brazil, with particular emphasis on the state of Rio de Janeiro.

Estratégias passivas de projeto reduzem significativamente o uso de ar condicionado e melhoram o conforto térmico dos usuários. Isto pode ser ilustrado através dos hospitais da Rede Sarah Kubitschek projetados pelo arquiteto João Filgueiras Lima, Lelé, cujas soluções além de propiciarem ambientes mais agradáveis e salubres, evitam o uso de sistemas mecânicos de resfriamento, reduzindo o consumo de energia elétrica. Deste modo, o presente artigo tem como objetivo avaliar o conforto térmico dos hospitais Sarah de Salvador e do Rio de Janeiro, através de medições in loco da temperatura do ar, umidade relativa do ar e velocidade do ar. A análise dos resultados foi baseada em leituras de projeto, na norma ASHRAE Standard 55/2004 e em parâmetros adquiridos na literatura especializada. Os resultados demonstram a preocupação de Lelé na incorporação de aspectos bioclimáticos nos projetos. No Sarah - Salvador, alguns ambientes permaneceram fora da zona de conforto no perÃodo do meio dia, devido ao ganho de calor pela cobertura. No entanto, o uso da ventilação natural auxilia no efeito de resfriamento, melhorando o conforto térmico nos espaços internos. Já no Sarah - Rio, todos os ambientes permanecem dentro da zona de conforto proposta pela ASHRAE 55.
