13. An overview of heavy oil properties and its recovery and transportation methods
Unconventional oils - mainly heavy oils, extra heavy oils and bitumens - represent a significant share of the total oil world reserves. Oil companies have expressed interest in unconventional oil as alternative resources for the energy supply. These resources are composed usually of viscous oils and, for this reason, their use requires additional efforts to

14. Methicillin-resistant Staphylococcus sp. colonizing health care workers of a cancer hospital
The aim of the study was to analyze epidemiological and microbiological aspects of oral colonization by methicillin-resistant Staphylococcus of health care workers in a cancer hospital. Interview and saliva sampling were performed with 149 health care workers. Antimicrobial resistance was determined by disk diffusion and minimum inhibitory concentration. Pol

15. Prevalence and phenotypic characterization of Enterococcus spp. isolated from food in Brazil
We evaluated the frequency of enterococci from food and found 95.2% of positivity, being E. faecium and E. faecalis the most frequent species. High-level streptomycin resistance was observed, as well as gelatinase and hemolysis activity, showing the potential role of environmental strains as reservoir of virulence and resistance traits.

16. Phytoplankton of two rivers in the eastern Amazon: characterization of biodiversity and new occurrences
During the various hydrological periods in 2011, we studied the phytoplankton along an 87-km stretch of the Araguari and Falsino rivers, which are located in the eastern Brazilian Amazon, in the state of Amapá, Brazil, the most ecologically preserved state in the country. In the study area, the aquatic ecosystem is under pressure from human activities such

17. Sensor químico baseado em microponte de impedância = : Chemical sensor based on impedance microbridge / Chemical sensor based on impedance microbridge
A integração de sistemas microeletrônicos em lab-on-a-chip está sendo cada vez mais necessária para concretizar novas aplicações dentro do emergente campo da microfluídica. Tanto na química quanto na bioquímica e até mesmo na medicina e bioengenharia, a microfluídica evolui conquistando um espaço crescente. Entretanto, desafios tecnológicos res

18. Molecular characterization of vanA-containing Enterococcus from migratory birds: song thrush (Turdus philomelos)
Vancomycin-resistant enterococci (VRE) were detected in two faecal samples (1.3%) of song thrush in Portugal. vanA isolates showed high level vancomycin/teicoplanin resistance, as well as resistance to ciprofloxacin, quinupristin-dalfopristin and cloranfenicol. Thrush can be a reservoir of VRE and transmit these resistant bacteria to other animals including

19. Genetic characterization of Bhutanese native chickens based on an analysis of Red Junglefowl (Gallus gallus gallus and Gallus gallus spadecieus), domestic Southeast Asian and commercial chicken lines (Gallus gallus domesticus)
The genetic diversity of Bhutanese chickens needs to be understood in order to develop a suitable conservation strategy for these birds in Bhutan. In this, work, we used microsatellite markers to examine the genetic diversity of Bhutanese chickens. Four Bhutanese chicken varieties (Black plumage, Frizzle, Naked neck and Red Junglefowllike, corresponding to Y

20. Sistemas alagados construídos para tratamento de águas residuárias do processamento dos frutos do cafeeiro: eficiência e caracterização das comunidades microbianas / Constructed wetlands systems for wastewater treatment in the processing of coffee fruits: eficiency and characterization of microbial communities
This study aimed to evaluate the influence of ryegrass cultivation (Lolium multiflorum Lam) and the artificial aeration of the affluent in the removal of organic matter, nutrients and phenolic compounds present in the ARC, as well as the diversity of microbial communities attached to the medium (gravel) and the rhizosphere of ryegrass, using T-RFLP multiplex

21. Caracterização da influência de sistemas frontais sobre a qualidade da água do reservatório de Itumbiara, GO, utilizando dados de sensoriamento remoto e dados in situ / Characterization of frontal systems influence on water quality of Itumbiara reservoir, GO, Brazil, using remote sensing and in situ data
In addition to human activities the water quality in reservoirs is influenced by weather and climate forcings that determine spatial and temporal variations in these systems. Conventional techniques for water quality monitoring require large time and fund investments. The synoptic view of large areas and high temporal frequency remote sensing data provides a

22. Caracterização de reservatórios fluviais da Bacia de Taubaté, SP / Fluvial reservoir characterization of Taubaté Basin, SP
A Bacia de Taubaté, localizada na porção leste do estado de São Paulo, ocupa uma área aproximada de 2400 km², estendendo-se ao longo do Vale do Rio Paraíba, desde Jacareí até a cidade de Cruzeiro. Posicionada no segmento central do Rifte Continental do Sudeste do Brasil, seu arcabouço estrutural é formado por semi-grábens, separados por zonas de

23. Métodos geoestatísticos de co-estimativas: aplicação aos dados do Campo Escola de Namorado / Co-estimation geostatistical methods: applications to the Namorado Oil Field data
Data used for studying petroleum reservoirs are obtained through drill core, well logs, seismic records and, as a consequence, they present different sampling scales. Multivariate geostatistics is a manner of integrating these data in order to co-estimate a poorly sampled variable based not only on its own information but also on a densely sampled variable.

24. Consolidação de um rejeito de mineração de areia e modelação do enchimento de um reservatório para sua disposição / Sand-mining waste disposal consolidation and a waste reservoir filling process modeling for its storage
Mining waste is frequently disposed of in the form of mud. The storage capacity of a collection reservoir of mining waste depends on its dimensions and on its operational processes, which are based on the physical characteristics of the mud and its compressibility and hydraulic conductivity. This research focuses on the study of the consolidation characteris
