Severe acute respiratory infections in the 2012/2013 season studied by the Port...

During the 2009/10 influenza pandemic, a network of 14 laboratories located in the main reference hospitals from Portugal mainland, Madeira and Azores was established for the diagnosis of the new influenza A(H1N1)2009 pandemic strain. Since then, the network performs laboratory diagnosis of influenza as well as other respiratory pathogens, thus contributing to the laboratory diagnosis of respiratory disease in ...

O verbo: um estudo sobre criatividade e individuação

Parental cognitive dimensions associated with preschool children’s eating habit...

Childhood excessive weight and obesity are a major public health concern from early childhood. Early childhood is an important period of development for developing healthy eating habits, that may be associated with an adequate present/future BMI. There is extensive evidence that children’s food intake is shaped by early experiences, suggesting ways in which parenting practices may be promoting obesity. But wha...

Estimativas de transporte na parte oriental da Corrente dos Açores

Tese de mestrado, Ciências Geofísicas (Oceanografia), Universidade de Lisboa, Faculdade de Ciências, 2009 ; Circulation patterns of the eastern part of the Azores Current are investigated through estimates of current velocities and volume transports using two sets of data: ARGO hydrographic data and also an absolute dynamic topography (ADT) product resulting from merging ARGO data with Altimetry data. Calculat...

Influence of Sodium Cations of N3 Dye on the Photovoltaic Performance and Stabi...

We report on the effect of substituting the two tetrabutyl am-monium counter ions of the standard N719 dye by sodium ions on the performance and stability of dye-sensitized solar cells (DSCs). The disodium analogue of N719 in conjunction with a non-volatile electrolyte gives a conversion efficiency of 7.6% under standard global AM 1.5 sunlight. Devices maintain 99% of their initial performance after 1000 h unde...

Influence of Different Cations of N3 Dyes on Their Photovoltaic Performance and...

The N3 dye was modified by substituting two of its protons by potassium or sodium cations. The performance and stability of dye-sensitized solar cells incorporating the new dyes were evaluated under light soaking (1000W · m−2 )at50◦C. Photocurrent measurements demonstrated that proton substitution by potassiumcations rends the systemmore stable. Further characterization of the potassium-based ...

Os verbos recíprocos no PB:: Interface sintaxe-semântica lexical

Esta dissertação toma como objeto de estudo os verbos recíprocos no português brasileiro (PB). Esses verbos se comportam de duas maneiras na sintaxe: numa forma simples, como em João e Maria conversam (na qual os participantes da reciprocidade são denotados por um argumento) e numa forma descontínua, como em João conversa com Maria (na qual os participantes da reciprocidade são denotados separadamente por dois ...

Prevalence of human papillomavirus infection in rural villages of the Bolivian ...

Cervical cancer constitutes a major health problem in developing countries like Bolivia. The roles of certain genotypes of human papillomaviruses (HPVs) in the pathogenesis of cervical cancer is well established. The prevalence of HPV infection among sexually active women varies greatly. Information regarding HPV infection in Bolivia is very much scarce, specially in regions like the Amazonian lowland. We studi...

Comparação do uso tópico de cetotifeno com a olopatadina no tratamento de conju...

Objetivo: Avaliar e comparar a eficácia e tolerância do uso tópico do fumarato de cetotifeno a 0,05% e cloridrato de olopatadina a 0,1% no tratamento de pacientes com conjuntivite alérgica. Método: Foi realizado estudo clínico mascarado, randomizado comparando a eficácia, segurança e os efeitos colaterais com o uso da solução oftálmica de fumarato de cetotifeno a 0,05% e cloridrato de olopatadina a 0,1% no alív...
