Mapping Persona Interaction with Scenarios
Gago, José; Marques, Tiago; Rolo, Ema; Pereira, Leonardo; Martins, NunoThe following article describes a Persona Method through Visual Clues and Socio-Economic Scenarios Interference (PMVC+) in a learning setting performed in the course of Design of Interfaces I, School of Arts, University of Evora, Portugal, in the academic year of 2021/22. The study follows a descriptive case methodology. Supported by previous work, the proposed PMVC+ concerns the project’s early stage and revea...
Profiling the Aroma of Grape Spirits for Port Wine Using a Multi-Analytical GC ...
Caldeira, Ilda; Loureiro, Maria; Martins, Nuno; Lourenço, Silvia; Cabrita, Maria joao; Silva, Ricardo; Rocha, Silvia; Alves, FernandoPort wine production involves the addition of grape spirit to halt fermentation and retain natural sweetness. This spirit, produced by distilling wine and its by-products, must comply with legal standards, including a mandatory sensory assessment. Because grape spirit influences Port wine’s volatile composition, this study investigated the odouractive compounds present in several grape spirits intended for fort...
Varietal Terpenoids and C13-Norisoprenoids in Alentejo Varietal Red Wines Acros...
Gastão-Muchecha, Sousa; Martins, Nuno; Garcia, Raquel; Cabrita, Maria JoãoThis study characterizes the volatile organic compound (VOC) profiles of young monovarietal red wines from five cultivars widely grown in Alentejo, Portugal—Aragonez, Castelão, Merlot, Syrah, and Trincadeira, across two consecutive vintages (2021 and 2022), in a total of 20 samples. Understanding how grape variety and harvest year shape VOC composition is essential for defining varietal typicity, supporting aut...
Water Stress Effects on Free and Bound Volatile Compounds in Macabeo and Chardo...
Cebrián-Tarancón, Cristina; Martins, Nuno; Fonseca, Daniela; Cabrita, Maria João; Salinas, Rosário; Alonso, Gonzalo; Sánchez-Gómez, RosarioClimate change and variable rainfall are pushing the wine industry to assess grapevine adaptability, as water deficit alters volatile compounds and understanding these processes is key to maintaining wine quality. A total of 64 compounds, free and glycosidically bound fractions, were analyzed using HS-SPME-GC×GC/ToFMS in Macabeo and Chardonnay grapes under two water irrigation regimes. Results showed that water...
Decoding the Communal Self: Ethnographic Documentary and Design as Methodologie...
Roberti, Ana Clara Nunes; Martins, Nuno; Brandão, DanielThis article draws on the interdisciplinary potentialities of design for societal intervention, to present and discuss approaches to ethnographic documentary in vulnerable socio-economic contexts, and specifically social housing neighborhoods. The article reflects on the impact of the approach taken in the project “Echoing the Communal Self: designing the dissemination and replication of self-initiated practice...
Self-initiated practices in the urban community of Balteiro: Design challenges ...
Martins, Nuno; Brandão, Daniel; Penedos-Santiago, Eliana; Alvelos, Heitor; Lima, Cláudia; Barreto, Susana; Roberti, Ana Clara NunesThis project aims to identify, document, interpret and disseminate current self-regulated community practices in social housing neighborhoods in the city of Vila Nova de Gaia, Portugal, in 2021. The main, specific case study is the neighborhood of Balteiro. We present methodologies and the first outcomes of the ethnographic work developed at Balteiro, namely an analysis of the origins, dynamics, needs and curre...
Comunicação de risco em saúde: Estratégias de design e de comunicação digital e...
Espanha, Rita; Martins, Nuno; Di Fátima, BrancoA pandemia de Covid-19 evidenciou o papel crucial da comunicação de risco em saúde pública e o impacto decisivo do design na gestão de crises. Entidades como a Direção-Geral da Saúde (DGS) e o Serviço Nacional de Saúde (SNS) desempe- nharam um papel central na disseminação de informações credíveis durante aquele período, contribuindo para a orientação dos cidadãos num cenário de incerteza. Este livro apresenta ...
The potential of enzymatic hydrolysis with HS-SPME-GC×GC-ToFMS for the study of...
Fonseca, Daniela; Martins, Nuno; Garcia, Raquel; Cabrita, Maria JoãoThis works focuses on developing an optimized methodology for analyzing free and bound volatile compounds in grapes using enzymatic hydrolysis with AR2000 enzyme and HS-SPME-GC × GC-ToFMS. To achieve this purpose, a previous optimization step of enzymatic hydrolysis was implemented and optimal conditions for enzymatic hydrolysis were established using 50 mg of AR2000 enzyme at 35 °C for 24 h, while the best ext...
Irrigation Regime Effects on Phenolic Composition of Portuguese Grape Varieties
Fonseca, Daniela; Sánchez-Gómez, Rosário; Salinas, Rosário; Cabrita, Maria João; Martins, Nuno; Garcia, Raquel; Cebrián-Tarancón, CristinaClimate change has led to increased extreme weather events, such as severe droughts and intense rainfall, with regions in Portugal, like Alentejo and Algarve, being particularly affected. Understanding the influence of water availability in the concentration of phenolic compounds in autochthonous varieties could be an important tool to know how these varieties adapt to water scarcity. This work has been carried...
Effect of high hydrostatic pressure treatment and vine-shoot chips on the volat...
Noviello, Mirella; Moreno, David; Martins, Nuno; Paradiso, Vito; Caponio, Francesco; Cabrita, Maria Joao; Valdés, EsperanzaThis study evaluates the impact of toasted vine-shoot chips and high hydrostatic pressure (HHP), applied either separately or in combination, on the volatile composition and sensory properties of Chardonnay wines to investigate their individual and synergistic effects on wine quality. Five treatments were carried out: (i) untreated wine as a control (W), (ii) wine macerated for 35 days with vine-shoot chips (12...
