The relationship between past exercise behavior and future exercise adherence: ...
Rodrigues, F.; Figueiredo, N.; Teixeira, D.; Cid, Luis; Monteiro, D.The present study explored the mediation role of past exercise adherence, self-reported frequency and intentions in the association between past experience and future exercise adherence. In total, 431 exercisers (female = 216; male = 215) aged 18 and 64 years, engaged in fitness activities such as group fitness classes and resistance training, were included in the analysis. Serial mediation procedures were empl...

The corrosion resistance of Wiron88 in the presence of S. mutans and S. sobrinu...
Proença, L.; Barroso, H.; Figueiredo, N.; Lino, A. R.; Capelo, S.; Fonseca, I. T. E."The corrosion resistance of Wiron®88, a Ni–Cr–Mo alloy, was evaluated in liquid growth media in the absence and presence of the Streptococcussobrinus and Streptococcus mutans strains. Open circuit potential measurements, cyclic voltammetry, linear sweep voltammetry, as well as electronic microscopy coupled to electron diffraction spectroscopy (SEM/EDS), were the main techniques used in this study. It was concl...
Impact of agricultural practices, elevated temperature and atmospheric carbon d...
Figueiredo, N.; Carranca, C.; Goufo, P.; Pereira, J.; Trindade, H.; Coutinho, J.Data on the movements of available N and non-exchangeable NH4 + in the soil are of crucial importance in designing an efficient plant N nutrition management scheme in paddy rice fields. To investigate the processes affecting the dynamics of N and pH under Mediterranean conditions, rice (Oryza sativa L. cv. Ariete) was cultivated in 2011 and 2012 in Salvaterra de Magos (central Portugal) under the following clim...
Elevated carbon dioxide and temperature effects on rice yield, leaf greenness, ...
Figueiredo, N.; Carranca, C.; Trindade, H.; Pereira, J.; Goufo, P.; Coutinho, J.; Marques, P.; Maricato, R.; de Varennes, A.Abstract The present field experiment was conducted during two consecutive cropping seasons in central Portugal to study the effects of simultaneous elevation of carbon dioxide concentration ([CO2]) (550 lmol mol-1 ) and air temperature (?2–3 C) on japonica rice (Oryza sativa L. ‘‘Ariete’’) yield, crop duration, and SPAD-values across the seasons compared with the open-field condition. Open-top chambers were us...

Proença, Luís; Barroso, H.; Figueiredo, N.; Lino, A.R.; Capelo, Sofia; Fonseca, I.T.E.The corrosion resistance of Wiron®88, a Ni–Cr–Mo alloy, was evaluated in liquid growth media in the absence and presence of the Streptococcus sobrinus and Streptococcus mutans strains. Open circuit potential measurements, cyclic voltammetry, linear sweep voltammetry, as well as electronic microscopy coupled to electron diffraction spectroscopy (SEM/EDS), were the main techniques used in this study.

Efectividade da Rede de Referenciação Perinatal da Região Centro
Costa, E.; Moleiro, P.; Carvalho, L.; Neves, F.; Oliveira, J.; Ventura, A.; Teixeira, A. L.; Martins, J.; Figueiredo, N.; Costa, R.; Peixoto, J.Resumo Em 1990 foi desenvolvida em Portugal uma Rede de Referenciação Perinalal, com definição dos limites e as responsabilidades assistenciais dos Hospitais de Apoio Perinatal Diferenciado (HAPD) e dos Hospitais de Apoio Perinatal (HAP). Graças ao espírito de cooperação c complementaridade desenvolvidos, os critérios de transferência iu útero e pós natal estão bem estabelecidos* Com os resultados do Registo Na...
Rice (Oryza sativa L.) phenolic compounds under elevated carbon dioxide (CO2) c...
Goufo, P.; Pereira, J.; Moutinho-Pereira, J.; Correia, C.; Figueiredo, N.; Carranca, C.; Rosa, E.; Trindade, HPrevious studies have shown that elevated levels of carbon dioxide [CO2] may increase, decrease, or have no effect on the concentrations of phenolic compounds in plants. The underlying causes of these variations in responses remain poorly understood. In the present study, it was hypothesized that different plant responses come mainly from the duration of exposure to the gas, growing conditions, and sampling pro...
Effect of elevated carbon dioxide (CO2) on phenolic acids, flavonoids, tocopher...
Goufo, P.; Pereira, J.; Figueiredo, N.; Oliveira, M.; Carranca, C.; Rosa, E.; Trindade, H.There have been no studies conducted with the objective of investigating the effect of elevated CO2 concentrations ([CO2]) on antioxidants in grains. Therefore, a two-year field experiment was conducted using open-top chambers with two levels of atmospheric CO2 (375 and 550 mmol/mol) to evaluate their effects on rice grain antioxidants. Following exposure to high [CO2], the total phenolic content of all rice mil...
A alteração climática na “fixação” do amónio em solos cultivados com arroz (Ory...
Figueiredo, N.; Carranca, C.; Coutinho, J.; Trindade, H.; Pereira, J.; Prazeres, A.; Marques, P.O arroz, é essencialmente produzido como monocultura, em canteiros alagados, nas regiões do centro e sul do País (Vales do Mondego, Tejo e Sado). O ião NH4 + é a forma de N mineral mais abundante e preferencialmente absorvida pelo arroz, em condições de alagamento. O alagamento potencia a mineralização, por acção dos microrganismos aeróbios facultativos, aumentando a sua concentração na solução do solo. No solo...
