Seaweed extracts to control postharvest phytopathogenic fungi in Rocha pear
Toledo, Eloísa; Félix, Carina; Vicente, Tânia F. L.; Augusto, Ana; Félix, Rafael; Toledo, Bernardo; Silva, Joana; Trindade, Carina; Raimundo, DélioFungal infections cause losses amounting to between 20 and 25% of the fruit industry’s total outcome, with an escalating impact on agriculture in the last decades. As seaweeds have long demonstrated relevant antimicrobial properties against a wide variety of microorganisms, extracts from Asparagopsis armata, Codium sp., Fucus vesiculosus, and Sargassum muticum were used to find sustainable, ecofriendly, and saf...
O tempo do espaço em branco : O lugar do kairos e do ócio numa pedagogia a part...
Augusto, AnaA partir das características de vivência do tempo, contidas nos conceitos clássicos de kairos e otium, que têm na sua base a experimentação de um tempo qualitativo, pretende-se perceber de que forma é que estes têm evoluído e que espaço ocupam no nosso quotidiano, particularmente no que respeita à educação e aos processos de criação artística teatral. Através do cruzamento entre os processos criativos de encena...
Preservation of fresh-cut Rocha Pear using Codium tomentosum extract
Augusto, Ana; Miranda, Andreia; Crespo, Daniel; Campos, Maria J.; Raimundo, Délio; Pedrosa, Rui; Mitchell, Geoffrey; Niranjan, KeshavanRocha is a Portuguese pear cultivar with high economic importance in the Portuguese Western Region. Degradative processes following its manipulation can quickly lead to product rejection, especially when sold as a freshcut product. The efficacy of a marine-based edible coating to inhibit superficial browning development in freshcut Rocha pear slices was investigated over a storage period of 15 days. The aqueous...

Augusto, Ana; Miranda, Andreia; Costa, Leonor; Pinheiro, Joaquina; Campos, Maria J.; Raimundo, Délio; Pedrosa, Rui; Mitchell, GeoffreyCodium tomentosum hydroethanolic extract was obtained using a pilot solid–liquid extractor to validate the anti-browning functionality of the extract under industrial conditions. Fresh-cut apple slices were coated by immersion in: (1) a seaweed extract solution (0.5% w/v) and (2) a commercial coating, and the two sets of samples were compared with a control (immersion in water). Packaged samples were stored, un...
Electrospun polycaprolactone (PCL) degradation: An in vitro and in vivo study
Dias, Juliana R.; Sousa, Aureliana; Augusto, Ana; Bártolo, Paulo J.; Granja, Pedro L.Polycaprolactone (PCL) is widely used in tissue engineering due to its interesting properties, namely biocompatibility, biodegradability, elastic nature, availability, cost efficacy, and the approval of health authorities such as the American Food and Drug Administration (FDA). The PCL degradation rate is not the most adequate for specific applications such as skin regeneration due to the hydrophobic nature of ...

Argan oil as a rich source of linoleic fatty acid for dietetic structured lipid...
Simões, Tiago; Ferreira, Jessica; Lemos, Marco F.L.; Augusto, Ana; Félix, Rafael; Silva, Susana F.J.; Ferreira-Dias, Suzana; Tecelão, CarlaArgan oil is rich in long-chain unsaturated fatty acids (FA), mostly oleic and linoleic, and natural antioxidants. This study addresses the production of low-calorie structured lipids by acidolysis reaction, in a solvent-free system, between caprylic (C8:0; system I) or capric (C10:0; system II) acids and argan oil, used as triacylglycerol (TAG) source. Three commercial immobilized lipases were tested: Novozym®...

Talaia, Mário; Augusto, AnaA obra publicada pelo Ministério da Educação e Ciência, Ensino Básico e Ensino Secundário apresenta um enquadramento curricular da Educação para o Risco que é hoje reconhecida como uma componente da formação da criança e do jovem que importa desenvolver desde os primeiros anos de vida. O Conselho Nacional de Educação sugere que se vive numa sociedade que é sistematicamente confrontada com notícias sobre a prese...
