Pires, Rosa; Guerra, Rui Manuel Farinha das Neves; Cruz, Sandra; Antunes, MDC; Brazio, António; Afonso, Andreia M.; Daniel, MarianaThe aim of this study was the non-destructive assessment of ‘Ortanique’ (Citrus reticulata Blanco x Citrus sinensis (L) Osbeck) ripening, based on the prediction of internal quality attributes (IQA) by short-wave near-infrared reflectance spectroscopy (SW-NIRS) calibration models. Spectra from fruit of 50 trees located in two different orchards, were acquired on tree using a customized portable visible near-inf...
Feature discovery in NIR spectroscopy based Rocha pear classification
Daniel, Mariana; Guerra, Rui Manuel Farinha das Neves; Brazio, António; Rodrigues, Daniela; M. Cavaco, A.; Antunes, Maria DulceNon-invasive techniques for automatic fruit classification are gaining importance in the global agro-industry as they allow for optimizing harvesting, storage, management, and distribution decisions. Visible, near infra-red (NIR) diffuse reflectance spectroscopy is one of the most employed techniques in such fruit classification. Typically, after the acquisition of a fruit reflectance spectrum the wavelength do...
Spatiotemporal modelling of the quality and ripening of two cultivars of "Algar...
Cavaco, Ana M.; Cruz, Sandra P.; Antunes, M. Dulce; Guerra, Rui; Pires, Rosa; Afonso, Andreia M.; Brazio, António; Silva, LeonardoAlgarve Citrus are non-climacteric Protected Geographical Indication (PGI) commodities. They are harvested with minimal levels of juice content (>35 %), soluble solids content (SSC) (>10 %) and maturation index (MI) (>8), as required by the respective PGI normative reference. These internal quality attributes (IQA) are usually determined in small samples of fruit collected from the orchards close to harvest. Th...
Uso da Vara com Instrumento em Crianças de 3 anos de idade: Affordances e Efeti...
Seabra, Ana Paula; Catela, David; Galvão, Teresa; Tomás, Catarina; Daniel, Mariana; Sabino, Solange; Rodrigues, ValériaPodemos alcançar o mesmo objetivo usando diferentes combinações de nossos segmentos corporais, fenómeno que é denominado de "equivalência motora" (Lashley, 1930). Um instrumento é um objeto destacável do meio ambiente, que é acoplado ao nosso corpo, e que pode ampliar a nossa capacidade de o explorar e modificar (Beck, 1980, cf. St Amant, & Horton, 2008). O processo de uso de um instrumento tem implicações neur...
