1. Molecular detection of flaviviruses and alphaviruses in mosquitoes (Diptera: Culicidae) from coastal ecosystems in the Colombian Caribbean
Arboviruses belonging to the genera Flavivirus and Alphavirus were detected in mosquitoes in a rural area of San Bernardo del Viento (Córdoba, Colombia). A total of 22,180 mosquitoes were collected, sorted into 2,102 pools, and tested by generic/nested reverse transcription-polymerase chain reaction. Venezuelan equine encephalitis virus, dengue virus, West

2. Influência dos modelos digitais de terreno na modelagem de circulação hidrodinâmica 2DH: um estudo de caso
Os modelos digitais de terreno (MDT) consistem na representação matemática computacional da distribuição de um fenômeno espacial que ocorre dentro de uma região da superfície terrestre. A qualidade da representação do MDT está influenciada, dentre outros fatores, pela origem do dado e pelo algoritmo interpolador utilizado. A caracterização da ci

3. A finite element model for the ocean circulation driven by wind and atmospheric heat flux
A finite element model for solving ocean circulation forced by winds and atmospheric heat fluxes is presented. It is vertically integrated 1 1/2 layer model which solves the motion and continuity hydrodynamic equations coupled with the advection-diffusion transport equation for temperature. A space-time Petrov-Galerkin formulation is used to minimize the und

4. Padrões diagenéticos em arenitos de sistemas de Sabk ha costeiros-eólicos: um estudo comparativo dos reservatórios Juruá da área de Urucu, Bacia de Solimões, AM
Coastal-eolian sabkha sandstones from different ages and basins show similar diagenetic patterns, which understanding is important for their evaluation as geochemical systems and as hydrocarbon reservoirs. The Carboniferous sandstones of the Juruá Formation (Solimões Basin) are one of the most important gas reservoirs of Brazil. The sandstones and interbed

5. Processos dinÃmicos e evolutivos da zona costeira de Itamaracà por sensoriamento remoto e medidas in situ
The coastal zone of Itamaracà is like a highly dynamic environment where land and oceanic processes interact altering frequently coastal characteristics. In this context, this current study examines the responsible processes of such changes from the development and application of methodologies, which includes digital image processing and the obtaining of in

6. Distribuição vertical e sazonal da comunidade fitoplanctônica em dois reservatórios eutróficos do Estado de Pernambuco
The dynamics of the phytoplankton community in aquatic ecosystems provides considerable diagnostic information and serves as a sensitive tool for the indication of environmental changes, enabling the prediction of changes in any body of water. The vertical distribution of these organisms in eutrophic reservoirs remains an under-explored field of study, but i

7. Estudo da circulação hidrodinâmica e da dispersão de óleo na zona costeira entre Macau e Galinhos RN
This paper presents a study on coastal hydrodynamics and the spread of an oil spill in waters off Macau and Galinhos, on the east coast of the state of Rio Grande do Norte in Northeast Brazil. This area has a very marked coastal dynamic owing to the complexity of its geomorphological features, developed in a regime of semidiurnal mesotides involving reefs, s

8. Análise crítica da utilização de modelagem matemática na avaliação da dispersão de efluentes leves no litoral da Baixada Santista ( Estado de São Paulo). / The analysis of mathematical models in the assessment of effuents dispersion in Baixada Santista coastline (State of São Paulo).
The prediction of the hydrodynamic water circulation and pollutants dispersion, mainly in coastal areas, has been a problem that engineers have been facing. This is due to the increase environmental impacts that involve coastal engineering work and management. The usage of mathematic modeling as assessment tool is necessary for these studies. The main purpos

9. Resposta da Plataforma Continental Sudeste a ventos sazonais e sinóticos de verão: estudos numéricos / Response of the South Brazil bight to summer seasonal and synoptic winds: numerical studie
In order to study the pertubations caused on the South Brazil Bigth (SBB) caused by the passage of a cold front during Summer, a mean basic state for currents was obtained using the POM (Princeton Ocean Model) through diagnostic simulation, followed by a short round prognostic. The mean currents modeled are in certain instancies similar to the currents measu

10. Reconstituição paleoambiental das enseadas do Flamengo e da Fortaleza, Ubatuba, S.P., durante o Holoceno, inferida a partir da variação das associações de foraminíferos / Paleoenvironmental reconstitution of Flamengo and Fortaleza bays, Ubatuba, SP, during the Holocene, inferred from the variations of Benthic foraminifera associations
Variations in Holocene environments in the marine bays of Flamengo and Fortaleza at Ubatuba, State of São Paulo, southeast Brazil, were detected in cores UB1 and UB3, respectively, on the basis of the distribution pattern of foraminiferal associations and their correlation with abiotic characteristics of the sediments. Correlations were then established bet

11. Praia da Boa Viagem, Recife-PE: anÃlise sÃcio-ambiental e propostas de ordenamento
Due to its environmental, social and economic complexity, beaches, especially urban beaches, need a special plan for their proper use. This planning must take into account the interaction between the environment (e.g. biota, substrate and water) and the socioeconomic and cultural scenarios (e.g. types of uses and conflicts). In this context, one of the main

12. Estudo filogeográfico de duas espécies de medusozoários (Cnidaria), Liriope tetraphylla (Trachymedusae, Gerioniidae) e Olindias sambaquiensis (Limnomedusae, Olindiasidae), em uma região do Oceano Atlântico Sul-Ocidental / Phylogeographic study of two medusozoan species (Cnidaria), Liriope tetraphylla (Trachymedusae, Geryoniidae) and Olindias sambaquiensis (Limnomedusae, Olindiasidae), in a region of the South Western Atlantic Ocean
Medusozoan species, with quite different life-cycles, inhabit different seas and oceans around the world. In a regional scale, some hydrozoan species are widespread along the Southwestern Atlantic Ocean (Brazilian and Argentinean shores), with populations distributed along a heterogeneous and structured environment. The relation between the distribution of t
