Influence of seasonality on the quality of oysters from the Sado and Mira rivers
Viana, Ana; Rodrigues, C.; Mata, A.; Salgado, R.; Palma, Silvina; Fidalgo, Liliana; Floro, António; Costa, Manuela; Carvalho, Maria JoãoThere is a lack of knowledge about the influence of seasonality on the microbial and physicochemical quality of oysters in Sado and Mira rivers. Water, sediment, and oysters (Crassostrea angulata and Crassostrea gigas) were collected for microbiological, nutritional, and sensory analyses. The microbiological water quality and the oyster shell contamination were better during the warmer months. No seasonal effec...

B.Made available in DSpace on 2022-04-29T07:48:20Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-06-20; Science and Technology Facilities Council; We present an archival search for transient gravitational-wave bursts in coincidence with 27 single-pulse triggers from Green Bank Telescope pulsar surveys, using the LIGO, Virgo, and GEO interferometer network. We also discuss a check for gravitational-wave si...

Nanostructured interfacial self-assembled peptide–polymer membranes for enhance...
Ribeiro, Sofia; Radvar, Elham; Yejiao Shi; Borges, J.; Pirraco, Rogério P.; Leonor, I. B.; Mano, J. F.; Reis, R. L.; Mata, A.; Azevedo, Helena S.Soft interfacial materials, such as self-assembled polymer membranes, are gaining increasing interest as biomaterials since they can provide selective barriers and/or controlled affinity interactions important to regulate cellular processes. Herein, we report the design and fabrication of multiscale structured membranes integrating selective molecular functionalities for potential applications in bone regenerat...
Co-assembly, spatiotemporal control and morphogenesis of a hybrid protein-pepti...
Inostroza-Brito, K. E.; Collin, E.; Siton-Mendelson, O.; Smith, K. H.; Monge-Marcet, A.; Ferreira, D. S.; Rodríguez, R. P.; Alonso, M.Controlling molecular interactions between bioinspired molecules can enable the development of new materials with higher complexity and innovative properties. Here we report on a dynamic system that emerges from the conformational modification of an elastin-like protein by peptide amphiphiles and with the capacity to access, and be maintained in, non-equilibrium for substantial periods of time. The system enabl...
A simulation-based approach for teaching the systems perspective of strategic p...
Capelo, C.; Lopes, A.; Mata, A.Kaplan and Norton introduced the balanced scorecard (BSC), which is based on a systems perspective of the business strategy and performance measurement. Many organisations around the world use the BSC to define, implement and manage strategy. Nevertheless, there are studies that identify problems and limitations associated with the implementation and use of the BSC. The contribution of this paper consists of pr...
Prosodic, syntactic, semantic guidelines for topic structures across domains an...
Mata, A.; Moniz, H.; Móia, T.; Gonçalves, A.; Silva, F.; Batista, F.; Duarte, I.; Oliveira, F.; Falé, I.This paper presents the annotation guidelines applied to naturally occurring speech, aiming at an integrated account of contrast and parallel structures in European Portuguese. These guidelines were defined to allow for the empirical study of interactions among intonation and syntax-discourse patterns in selected sets of different corpora (monologues and dialogues, by adults and teenagers). In this paper we foc...
Teenage and adult speech in school context: building and processing a corpus of...
Mata, A.; Moniz, H.; Batista, F.; Hirschberg, J.We present a corpus of European Portuguese spoken by teenagers and adults in school context, CPE-FACES, with an overview of the differential characteristics of high school oral presentations and the challenges this data poses to automatic speech processing. The CPE-FACES corpus has been created with two main goals: to provide a resource for the study of prosodic patterns in both spontaneous and prepared unscrip...
Co-assembled and microfabricated bioactive membranes
Mendes, A. C.; Smith, K. H.; Tejeda-Montes, E.; Engel, E.; Reis, R. L.; Azevedo, Helena S.; Mata, A.The fabrication of hierarchical and bioactive self-supporting membranes, which integrate physical and biomolecular elements, using a single-step process that combines molecular self-assembly with soft lithography is reported. A positively charged multidomain peptide (with or without the cell-adhesive sequence arginine-glycine-aspartic acid-serine (RGDS)) self-assembles with hyaluronic acid (HA), an anionic biop...
Spontaneous co-assembly of molecularly designed building blocks into hierarchic...
Smith, K. H.; Inostroza, K. E.; Alonso, Matilde; Reis, R. L.; Azevedo, Helena S.; Mata, A.A major limitation in generating materials using bottom-up strategies is the lack of order at the macroscale. In this work, we show that two self-assembling molecules, an elastin-like polymer (ELP) and a peptide amphiphile (PA), can interact to spontaneously to form hierarchically ordered, dynamic, bioactive, macrotubes. An RGD-containing ELP and a PA (C16V3A3K3) were synthesised using standard methods. The add...
