Queiroz,Gabriela Marina Pompeo; Silva,Marcos Rivail da; Bianco,Renata Joaquim Ferraz; Pinheiro,Adilson; Kaufmann,VanderGlyphosate was determined in runoff and leaching waters in agricultural soil that received an application of active ingredient and was exposed to simulated intensive rain conditions. The concentrations decreased during the simulation period and the concentrations of the runoff were higher than those achieved in the samples of leaching waters. The concentrations were lower than the pattern in the Brazilian Regul...
Terceira lavas isotopic sigantures and multi-scale mantle heterogeneity at the ...
Madureira, Pedro; Mata, João; Mattielli, Nadine; Queiroz, GabrielaTerceira Island mafic lavas (< 30 ka), erupted from two main active volcanic systems, were analysed in this study: Fissural zone (F), interpreted as the sub aerial expression of the Terceira Rift, and Sta Bárbara central volcano (SB), which dominates the western topography of the island. These mafic lavas present a significant elemental range, with SB (Mg# <50) being generally more evolved than F (typically Mg...

Impacto do estudo urodinâmico em mulheres com incontinência urinária
Araujo,Maíta Poli de; Oliveira,Emerson de; Queiroz,Gabriela Cabral; Pimentel,Silvia Helena C. de O.; Takano,Cláudia Cristina; Sartori,Marair Gracio F.OBJETIVO: Avaliar a tolerabilidade das pacientes com incontinência urinária submetidas ao estudo urodinâmico (EUD). MÉTODOS: Foram avaliadas 49 pacientes com queixas do trato urinário inferior submetidas ao estudo urodinâmico. Por meio de um questionário, as pacientes respondiam sobre seus anseios em relação ao exame a que iriam se submeter (medo, vergonha, ansiedade) e a expectativa de dor, por meio de uma esc...
Características elementares e isotópicas (He e Ne) das lavas da Terceira (Açore...
Madureira, Pedro; Mata, João; Moreira, Manuel; Queiroz, GabrielaAs razões isotópicas de He e de Ne permitem relacionar a ilha Terceira com uma pluma profundamente enraizada. Ainda que os os elementos incompatíveis apontem para o início da fusão parcial na zona da granada, as suas lavas apresentam, a maior parte das vezes, um carácter transicional e hiperstena normativa, que contrasta com o referenciado para algumas das ilhas da Macaronésia (e.g. Canárias e Cabo Verde). Esta...
Chemical variation on one single basaltic lava flow from Terceira Island (Azore...
Madureira, Pedro; Mata, João; Queiroz, GabrielaSeveral processes controlling magma rheology, crystallisation and cooling are believed to occur in magma chambers in order to generate layered intrusions (e.g. Bottinga and Weil 1970; McBirney, 1996). These processes are also expected to develop an important role in the differentiation of cogenetic lava series through fractional crystallisation. For Terceira island, several rock samples coming from one single b...
STRAIN AND RHEOLOGY WITHIN A TRACHYTIC FLOW: A meso-scale example from the Terc...
Lourenço, Nuno; Marques, Fernando; Madureira, Pedro; Ribeiro, António; Mata, João; Queiroz, Gabriela; Miranda, MiguelFault kinematic indicators are widely used to constrain local and regional stress fields at the origin of a fault population. We present clear tectonic like structures, which were developed and are confined within a trachytic flow at the Terceira Island. Its tectonic pattern when considered as a whole is consistent with the dynamic history of the cooling flow rather than with the regional tectonic stress field....
Multiple olivine He isotopic signatures from a single rock sample
Madureira, Pedro; Moreira, Manuel; Mata, João; Queiroz, GabrielaFor a porphyritic basaltic sample from Terceira Island, He isotopic analysis of 3 distinct olivine separates defined by petrographic characteristics and composition. He isotopic ratios range between 8.6 and 9.7 R/Ra and interpreted in function of magmatic evolution and and host rocks assimilation processes.
Atipias de Células Escamosas de Significado Indeterminado (ASCUS): estudo de 20...
Eleutério Junior,José; Cavalcante,Diane Isabelle Magno; Dias,Maria Tereza M. P.; Alves,Rossana M.; Queiroz,Gabriela C.; Proença,Aline R.Objetivos: avaliar aspectos clínicos, colposcópicos e acompanhamento citológico de quadros classificados como atipias de células escamosas de significado indeterminado (ASCUS). Métodos: foram analisados retrospectivamente 208 casos de ASCUS diagnosticados entre 1996 e 1998 e tabulados quanto a idade, queixas clínicas, colposcopia e seguimento. Resultados: a relação ASCUS:lesão intra-epitelial escamosa foi de 1:...
