1. Eucoleus contortus (Nematoda: Capillariidae), a parasite of Cairina moschata domestica (Anseriformes: Anatidae) on Marajó Island, Pará State, in Brazilian Amazon
Resumo A família Capillariidae é uma das mais importantes da superfamília Trichinelloidea, com 27 gêneros e mais de 300 espécies parasitando os vertebrados. Este estudo considera a morfologia, morfometria e prevalência de Eucoleus contortus parasito do esôfago de pato doméstico na Ilha de Marajó, Estado do Pará, Brasil. Morfologicamente os nematód

2. Angiostrongylus spp. in the Americas: geographical and chronological distribution of definitive hosts versus disease reports
BACKGROUND Angiostrongyliasis is an infection caused by nematode worms of the genus Angiostrongylus. The adult worms inhabit the pulmonary arteries, heart, bronchioles of the lung, or mesenteric arteries of the caecum of definitive host. Of a total of 23 species of Angiostrongylus cited worldwide, only nine were registered in the American Continent. Two spe

3. The impact of eggshell colour and spot area in Japanese quails: I. eggshell temperature during incubation and hatching results
ABSTRACT This study was carried out to investigate the effects of eggshell colour and spot properties (colour and size of the spot area) on eggshell incubation temperature and hatching outcomes of Japanese quail eggs (Coturnix coturnix japonica). Study material was allocated to five groups according to their eggshell and spot colours: black spots on greyish

4. Molecular findings from influenza A(H1N1)pdm09 detected in patients from a Brazilian equatorial region during the pandemic period
After the World Health Organization officially declared the end of the first pandemic of the XXI century in August 2010, the influenza A(H1N1)pdm09 virus has been disseminated in the human population. In spite of its sustained circulation, very little on phylogenetic data or oseltamivir (OST) resistance is available for the virus in equatorial regions of Sou

5. Impactos de El Niño y La Niña en las lluvias del Perú (1965-2007)
The impacts of El Niño (EN) and La Niña (LN) in rainfall in Peru are evaluated using monthly data (1965-2007) of 155 stations distributed over the three hydrographic drainages of Peru: 85 in the Pacific (VP), 21 in the Lake Titicaca (VT) and 49 in the Amazon (VA). To classify El Niño and La Niña is used the Index Troup Southern Oscillation (SOI) based on

6. Relação entre a ocorrência do contra eletrojato equatorial e o aparecimento de oscilações de pequena escala na região E / Relation between the occurrence of counter equatorial eletrojet and small scale oscillations in the E region
A Dissertação de Mestrado apresenta evidências da correlação entre as oscilações de pequena escala, compatíveis com ondas de gravidade, e do aparecimento de contra eletrojato equatorial (CEJ). Para identificar as condições de CEJ foram utilizados os dados de velocidade das irregularidades do tipo 2 mostradas nos dados do radar RESCO, o qual está i

7. A further contribution to the knowledge of Pectiniunguis minutus (Demange, 1968), a little known dwarf schendylid centipede from western equatorial Africa (Chilopoda: geophilomorpha)
El quilópodo geofilomorfo Pectiniunguis minutus (Demange, 1968), una especie enana de Schendylidae pobremente conocida de Gabon (Africa ecuatorial occidental), se redescribe e ilustra en base al material tipo y a un espécimen adicional no tipo conservados en las colecciones del Muséum national d' Histoire naturelle, París. P. minutus se puede diferenciar

8. Genetic-morphometric variation in Culex quinquefasciatus from Brazil and La Plata, Argentina
Variation among natural populations of Culex (Culex) quinquefasciatus Say is associated with different vectorial capacities. The species Cx. quinquefasciatus is present in the equatorial, tropical and subtropical zones in the Brazilian territory, with intermediate forms between Cx. quinquefasciatus and Culex pipiens occurring in regions of latitudes around 3

9. Estudo da ionosfera da região brasileira com dados dos satélites FORMOSAT-3/COSMIC e de Digissondas / Study of Brazilian region ionosphere using data from the FORMOSAT-3/COSMIC Satellites and Digisondes
Este trabalho visa melhorar o estudo da ionosfera da região brasileira com a utilização de dados da constelação de satélites FORMOSAT-3/COSMIC que fornece dados globais da atmosfera quase em tempo real. Os dados ionosféricos destes satélites permitem a construção de mapas dos parâmetros para monitorar o desenvolvimento e a manutenção das estrutu

10. Características da precipitação pluviométrica do nordeste brasileiro e seus padrões de acoplamento com as TSM do Pacífico Equatorial e Atlântico Sul. / Rainfall characteristics in northeastern brazil and their patterns coupling with sst equatorial Pacific and South Atlantic.
The eastern coast of the Northeast Brazil (NEB) is a region where transient weather systems interact with local systems, modulating their frequency and intensity. Understanding the mechanisms of such interactions may be instrumental in explaining the observed precipitation patterns in this region. The objective of this work is quite within this scope and tak

11. Electric and magnetic field signatures of gravity waves and 2-day planetary waves in the equatorial E-region / Assinaturas nos campos elétricos e magnéticos às ondas de gravidade e ondas planetárias de 2-dias na região E equatorial
Equatorial electrojet (EEJ) observations using VHF radars show backscattered echoes from two types of electron density irregularities explained by the modified two-stream (Type I) and the gradient drift (Type 11) instabilities. From the Type II irregularity velocities obtained by radar data we have inferred the vertical electric fields (E_z). The harmonic an

12. Performance evaluation of GPS receiver under equatorial scintillation
Abstract: Equatorial scintillation is a phenomenon that occurs daily in the equatorial region after the sunset and affects radio signals that propagate through the ionosphere. Depending on the temporal and spatial situation, equatorial scintillation can represent a problem in the availability and precision of the Global Positioning System (GPS). This work is
