Life cycle assessment of two diets for finishing Bísaro boars - a case study to...
Martin, L.; Santos, A.; Amaral, F.; Silva, D.; Ressurreição, S.; Ramos, A.; Charneca, R.; Costa, F.; Marmelo, C.; Martins, J.M.Improving animal feed efficiency to reduce Greenhouse Gas Emissions (GGE) is part of the support to be granted under the new Common Agricultural Policy Strategic Plan for Portugal. Pig producers do not have many alternatives to reduce the carbon footprint impact of their pork as the Feed Industry (FI) that supplies them still buys low-cost ingredients from the world market without considering their environmenta...
Primeiro registo de trilobites no Silúrico de Portugal (Sinclinal de Moncorvo)
Pereira, Sofia; Silvério, Gonçalo; Colmenar Lallena, Jorge; Moreira, Noel; Silva, D.; Sá, ArturRESUMO: A ocorrência de fósseis de trilobites em Portugal é conhecida desde há mais de 150 anos, mas permanecia por comprovar a presença deste grupo nas litologias do Silúrico. Reporta-se agora o primeiro registo de trilobites no Silúrico de Portugal, numa sucessão de intercalações de argilitos e calcários da Formação Campanhó do Sinclinal de Moncorvo. As trilobites são raras, estando a associação amplamente do...
Long-Term Physical Activity Modulates Lipid Metabolism and Gene Expression in M...
Martins, José Manuel; Albuquerque, A.; Silva, D.; Neves, J.; Charneca, R.; Freitas, A.This study examined the effect of long-term physical activity during the finishing period on meat and fat quality, and metabolic gene expression in obese Alentejano (AL) pigs. From 87.3 to 161.6 kg BW and for 130 days, eighteen pigs were assigned to either individual pens without an exercise area (NE, n = 9) or an outdoor park with an exercise area (WE, n = 9). Both groups received identical commercial diets at...
The Acute Effects of a Fast-Food Meal Versus a Mediterranean Food Meal on the A...
Silva, D.; Mendes, F.C.; Stanzani, V.; Moreira, R.; Pinto, M.; Beltrao, M.; Sokhatska, O.; Severo, M.; Padrão, Patrícia; Garcia-Larsen, V.; Delgado, L.Background/Objectives: This study aimed to assess the acute effects of two isoenergetic but micronutrient-diverse meals-a Mediterranean-like meal (MdM) and a fast food-like meal (FFM)-on the autonomic nervous system (ANS), lung function, and airway inflammation response. Methods: Forty-six participants were enrolled in a randomized crossover clinical trial, consuming two isoenergetic meals: FFM (burger, fries, ...
Harmony at home—nurturing work-pet family enrichment and harmony through a self...
Silva, D.; Junça Silva, A.; Pinheiro, P.Work-pet[family] enrichment has been recognised as an important part of the work-family boundaries as many families have pets of their own. Despite its increasing importance for both families and organisations, so far, no studies have explored how and when it increases harmony at home. Relying on the self-determination theory, we argued that work-pet[family] enrichment would improve employees' harmony through t...
Folie à deux? How Mavericks shape the relationship between the dark triad and n...
Silva, D.; Junça-Silva, A.; Pinheiro, P.This study used the trait activation theory to develop a conceptual model that explained how and when the dark triad state influenced negative deviant behaviours (NDB). For that, we tested malevolent creativity as a mediating variable and maverickism as a moderator. Diary data was collected from 54 working adults (324 measurement occasions). The multilevel results showed that (1) all the DT states had a positiv...

Use of videogames, internet gaming disorder, and agressiveness in emerging adul...
Silva, D.; Maia, B. R.Introduction: Internet gaming disorder has been associated with an excessive number of hours spent playing video games, which leads to a detriment of other daily activities and interests. In addition, it is associated with personality traits such as aggression and anger. In Portugal this relations are almost unexplored. Objectives: To explore the relationship between video game use, internet gaming disorder and...
Digital transformation in Portuguese architecture studios: Insights from the field
Silva, D.; Paio, A.The integration of digital tools in architecture is revolutionizing the field, affecting design processes, construction precision, and project management. This study explores the digital transformation of Portuguese architecture studios, focusing on the adoption and impact of digital tools such as Building Information Modeling (BIM) and digital fabrication. Through qualitative analysis of interviews with nine a...
Smart IoT lightning system for energy consumption optimization
Silva, D.; Mataloto, B.; Coutinho, C.This research details the development of a smart lighting system designed to optimize energy consumption by dynamically adjusting the brightness of a Tapo L530E smart lamp based on real-time ambient light measurements. The system integrates a light intensity sensor, an Arduino MKR WAN 1300 Lora, a Sonoff Dual R3 power consumption monitor, and a Tapo L530E smart lamp, with data communication facilitated through ...
