Infeção assintomática por Bordetella pertussis na população adulta portuguesa, ...
Palminha, P.; Costa, I.; Pinto, S.; Roquette, R.; Nunes, B.; Moura, S.; Neves, R.; Lourenço, T.; Ribeiro, C.; Pereira, B.Introdução: Em Por tugal e apesar da alta cober tura vacinal o número de casos de tosse convulsa notificados tem vindo a aumentar. A reemergência da tosse convulsa em países com elevadas cober turas vacinais tem tornado par ticularmente relevante a avaliação da infeção por Bordetella per tussis em adultos, descrita como assintomática ou ligeiramente sintomática, pela possibilidade de transmissão da bactéria aos...
Challenges for sustainable monitoring and evaluation of the EU Marine Strategy ...
Campuzano, F.; García, M.; Dabrowski, T.; Groom, S.; Ruiz-Villarreal, M.; Brotas, V.; Kaufmann, M.; Hartman, S.; Oliveira, P.; Martins, A.; Juliano, M.The European Atlantic Area in situ characterization/monitoring is challenging due to the high costs involved (24% of total EU waters for 12% of total population). The implementation of the EU Marine Strategy Framework Directive (MSFD) is complex if the objective is to extend periodic monitoring programs to offshore waters. Remote sensing and modelling have been recognised by the Copernicus Marine Service as sui...
Predicting the effectiveness of different mulching techniques in reducing post-...
Vieira, D. C. S.; Serpa, D.; Nunes, J. P. C.; Prats, S. A.; Neves, R.; Keizer, J. J.Wildfires have become a recurrent threat for many Mediterranean forest ecosystems. The characteristics of the Mediterranean climate, with its warm and dry summers and mild and wet winters, make this a region prone to wildfire occurrence as well as to post-fire soil erosion. This threat is expected to be aggravated in the future due to climate change and land management practices and planning. The wide recogniti...
Métodos de manejo de Cyperus esculentus na lavoura de arroz irrigado
Panozzo, L.E.; Agostinetto, D.; Galon, L.; Moraes, P.V.D.; Pinto, J.J.O.; Neves, R.As espécies da família Cyperaceae incluem-se entre as principais plantas daninhas que infestam as lavouras de arroz irrigado no Rio Grande do Sul. Objetivou-se com este trabalho avaliar o controle de Cyperus esculentus, a seletividade e a produtividade de grãos de arroz, cultivar Qualimax 1, em função de épocas de início da irrigação por inundação, épocas de aplicação e doses do herbicida penoxsulam. O experime...
The effect of long-chain polyunsaturated fatty acids intake during pregnancy on...
Pereira-da-Silva, Luís; Cabo, C.; Moreira, Ana Catarina; Papoila, A. L.; Virella, Daniel; Neves, R.Objective - The adjusted effect of long-chain polyunsaturated fatty acid (LCPUFA) intake during pregnancy on adiposity at birth of healthy full-term appropriate-for-gestational age neonates was evaluated. Study Design - In a cross-sectional convenience sample of 100 mother and infant dyads, LCPUFA intake during pregnancy was assessed by food frequency questionnaire with nutrient intake calculated using Food Pro...
Modeling SST and chlorophyll patterns in a coupled estuary-coastal system of Po...
Vaz, N.; Mateus, M.; Plecha, S.; Sousa, M. C.; Leitão, P. C.; Neves, R.; Dias, J. M.This work studies the influence of the Tagus estuary, Portugal, on the near coastal systemusing amodel application to describe the main physical and biogeochemical processes in the Region of Freshwater Influence (ROFI). It was used as nested modeling approach, downscaling the solution for the general circulation from a larger domain model (the Portuguese coast), to the local Tagus estuary domain. The model is e...
A process-oriented model of pelagic biogeochemistry for marine systems. Part II...
Mateus, M.; Vaz, N.; Neves, R.The main goal of this study is to use an integrated ecosystem model to study the role of physical, chemical and environmental parameters on the biogeochemistry of the Tagus estuary, the main estuarine system in Portugal. This work was developed as part of EU-funded INSEA project and tried to accomplish two major aims: (1) the development and implementation of a coupled modeling system capable of reproducing all...
Does the intake of LC-PUFAS during pregnancy affect the body composition of ter...
Camões, T.; Silva, A.; Neves, R.; Pereira-da-Silva, Luís; Moreira, Ana Catarina; Virella, Daniel; Alves, M.; Papoila, A. L.; Serelha, M.; Mendes, LinoBackground: The effect of the intake of polynsaturated long chain fatty acids (LCPUFAs) during pregnancy on fetal body composition has been assessed by studies using mostly neonatal anthropometry. Their results have been inconsistent, probably because neonatal anthropometry has several validity limitations. Air displacement plethismography (ADP) is a recently validated non-invasive method for assessing body com...
Benthic biodiversity patterns in Ria de Aveiro, Western Portugal: Environmental...
Rodrigues, A. M.; Quintino, V.; Sampaio, L.; Freitas, R.; Neves, R.This study characterizes the macrobenthic gradients in Ria de Aveiro, Western Portugal. Ria de Aveiro is the meeting place of a number of river basins, resulting in a transition system of complex geometry, with channels running parallel to the coast line, north and south of the entrance, but also inland, creating an intricate system of navigation channels, islands and intertidal sand and mudflats. This renders ...
Hydrological modelling of Maranhão and Pracana Basins, a first approach
Venâncio, A.; Neves, R.; Martins, Flávio Augusto Bastos da CruzModelling the hydrology of hydrographic basins has shown itself as a useful tool in environment management. The hydrological models can be used for multiple purposes: estimate runoff from sequences of rainfall, access stream water quality, quantify the diffuse pollution that reaches water masses such as estuaries, rivers and lakes, etc. This study has as final objective to simulate and analyse the flow, sedimen...
