Evaluation of the fertilizer potential of Chlorella vulgaris and Scenedesmus ob...
Alvarenga, Paula; Martins, M.; Ribeiro, Henrique; Mota, M.; Guerra, I.; Cardoso, H.; Silva, J. L.Producing microalgae with agricultural drainage water (ADW) allows recycling water and nutrients, with the produc- tion of a biofertilizer, avoiding receiving waters' contamination. Chlorella vulgaris and Scenedesmus obliquus were culti- vated using ADW and standard media supplementation and presented higher productivities, relatively to the control industrial growth medium (using freshwater). Selected strains ...
Effects of LED lighting on Nannochloropsis oceanica grown in outdoor raceway ponds
Carneiro, M.; Maia, Inês Beatriz; Cunha, P.; Guerra, I.; Magina, T.; Santos, Tamara; Schulze, Peter S.C.; Pereira, H.; Malcata, F. X.; Navalho, J.Growth in most microalgal mass cultivation systems is light-limited, particularly in raceway ponds (RWP) where the light path is higher. Artificial lighting can be a promising solution to diminishing dark zones and enhance microalgal productivity. Therefore, our goal was to prevent the cell shift from photosynthesis to a respiration-only stage by resorting to LED illumination. Nannochloropsis oceanica cultures ...

Increased red cell distribution width in Fanconi anemia: a novel marker of stre...
Sousa, R.; Gonçalves, C.; Guerra, I.; Costa, E.; Fernandes, A.; Bom-Sucesso, M.; Azevedo, J.; Rodriguez, A.; Rius, R.; Seabra, C.; Ferreira, F.BACKGROUND: Red cell distribution width (RDW), a classical parameter used in the differential diagnosis of anemia, has recently been recognized as a marker of chronic inflammation and high levels of oxidative stress (OS). Fanconi anemia (FA) is a genetic disorder associated to redox imbalance and dysfunctional response to OS. Clinically, it is characterized by progressive bone marrow failure, which remains the ...
Coping strategies of long-term unemployed in Portugal
Suleman, F.; Amor, T.; Guerra, I.This paper examines coping strategies adopted by women and men after job loss in Portugal. The data were gathered through interviews and an open-ended inquiry applied to fifteen unemployed persons (eight women), who were asked to describe their cognitive and behavioural efforts to cope with unemployment. Almost all the sampled unemployed persons search for a job, accept or look for training, do odd jobs, or req...
Residential trajectories in the Lisbon Metropolitan Area: Social profiles, mobi...
Pinto, T. C.; Ferreira, A. C.; Guerra, I.The article is the result of the research project ‘Residential Trajectories and Metropolization: Continuities and Changes in the Lisbon Metropolitan Area’ and analyses the residential trajectories of families in Lisbon. Following some international studies, our overriding objective is to examine the relationship between housing dynamics and family and professional contexts related to moving house. We observe th...
