Innovative moments and change in Career Construction Counseling
Cardoso, P; Silva, J.; Gonçalves, M. M.; Duarte, M. E.This article presents an intensive analysis of a career counseling case—the case of Michael—using the Innovative Moments Coding System (IMCS) and the Return to the Problem Coding System (RPCS). Both systems are grounded in a narrative conception of the self which suggests that narrative change results from the elaboration and development of narrative exceptions to a client’s core problematic self-narrative. The...
Uptake and depuration of PCB-153 in edible shrimp Palaemonetes varians and huma...
Grilo, T. F.; Cardoso, P. G.; Pato, P.; Duarte, A. C.; Pardal, M. A.A medium-term mesocosm exposure study was conducted to elucidate bioaccumulation and depuration of polychlorinated biphenyl congener 153 (PCB-153) in edible shrimp Palaemonetes varians. Over the 15-day exposure period, shrimp under different exposure concentrations exhibited a significant increase in PCB153 concentration compared with control organisms. Distinct bioaccumulation patterns and uptake rates ...
Mercury bioaccumulation and the population dynamics of Mesopodopsis slabberi (C...
D'Ambrosio, M.; Marques, S. C.; Azeiteiro, U. M.; Pardal, M. A.; Pereira, E.; Duarte, A. C.; Cardoso, P. G.The mercury bioaccumulation and population dynamics of the mysid Mesopodopsis slabberi was assessed along a mercury gradient in Ria de Aveiro (Portugal). M. slabberi is one of the most important mysid species in European temperate coastal shallow waters playing a key ecological role. Nevertheless, no references were found concerning the possible consequences of the Hg on the trophodynamics of these coastal ecos...
Impact of mercury contamination on the population dynamics of Peringia ulvae (G...
Cardoso, P. G.; Sousa, E.; Matos, P.; Henriques, B.; Pereira, E.; Duarte, A. C.; Pardal, M. A.The effects of mercury contamination on the population structure and dynamics of the gastropod Peringia ulvae (also known as Hydrobia ulvae) and its impact on the trophic web were assessed along a mercury gradient in Ria de Aveiro (Portugal). The gastropod was revealed to be a tolerant species to the contaminant, since the highest densities, biomasses and growth productivity values were recorded at the intermed...
pH influence on oxygen mass transfer coefficient in a bubble column. Individual...
Ferreira, António; Cardoso, P.; Teixeira, J. A.; Rocha, F.Experiments were performed in a laboratory scale bubble column (10 L), to investigate the pH influence on oxygen mass transfer coefficient, in order to achieve a better control of biological processes. The liquid-side mass transfer coefficient, kL, and the specific interfacial area, a, were studied individually. The specific interfacial area was obtained using the new automatic image analysis technique develope...
On the origin of the electrical response of vapor grown carbon nanofiber + epox...
Silva, J.; Cardoso, P.; Paleo, A.J.; van Hattum, F. W. J.; Simões, Ricardo; Lanceros-Méndez, S.The origin of the electrical response of vapor grown carbon nanofiber (VGCNF) + epoxy composites is investigated by studying the electrical behavior of VGCNF with resin, VGCNF with hardener and cured composites, separately. It is demonstrated that the onset of the conductivity is associated to the emergence of a weak disorder regime. It is also shown that the weak disorder regime is related to a hopping dependi...
Temperature dependence of the electrical conductivity of vapor grown carbon nan...
Cardoso, P.; Silva, J.; Agostinho Moreira, J.; Klosterman, D.; van Hattum, F.W.J.; Simões, Ricardo; Lanceros-Mendez, S.The influence of the dispersion of vapor grown carbon nanofibers (VGCNF) on the electrical properties of VGCNF/epoxy composites has been studied. A homogeneous dispersion of the VGCNF does not imply better electrical properties. The presence of well distributed clusters appears to be a key factor for increasing composite conductivity. It is also shown that the main conduction mechanism has an ionic nature for c...
The role of disorder on the AC and DC electrical conductivity of vapour grown c...
Cardoso, P.; Silva, J.; Klosterman, D.; Covas, J.A.; van Hattum, F.W.J.; Simões, RicardoFour dispersion methods were used for the preparation of vapour grown carbon nanofibre (VGCNF)/epoxy composites. It is shown that each method induces certain levels of VGCNF dispersion and distribution within the matrix, and that these have a strong influence on the composite electrical properties. A homogenous VGCNF dispersion does not necessarily imply higher electrical conductivity. In fact, it is concluded ...
Raça caprina Charnequeira
Andrade, C.S.C.R.; Cardoso, P.A cabra Charnequeira que deve o seu nome à sua área de exploração – a charneca – é um animal de aptidão mista, leite/carne. Subdivide-se em duas variedades, alentejana e beiroa, sendo esta última mais encorpada com cornos mais pequenos, inclinados para trás e menos retorcidos e, também, melhor produtora de leite. Parece que esta raça procede da Cabra Aegagrus, tendo mais tarde recebido influência do tronco Pire...
Long-term changes in the production by estuarine macrobenthos affected by multi...
Dolbeth, M.; Cardoso, P. G.; Grilo, T. F.; Bordalo, M. D.; Raffaelli, D.; Pardal, M. A.The macrobenthic production of an estuarine system was evaluated over a 14-year study period in a seagrass bed and in a sandflat. Over this period, the estuary suffered severe eutrophication and extreme weather events with important impacts on the community, impairing system functioning and ultimately the goods and services provided by the estuary (decline in the seagrass bed, decreased community production and...
