Enhancement of energy performance in cheese ripening chambers through renewable...
Garcia, João; Dias, João; Semedo, Arian; Teixeira, Tiago; Calvo, FranciscoThis research explores the integrated application of renewable energy sources—specifically wind, solar thermal, and photovoltaic—combined with Phase Change Materials (PCMs) to enhance energy efficiency and reduce CO₂ emissions in the production of traditional ewe’s milk cheese. Particular emphasis is placed on optimizing the cooling mechanisms within cheese ripening chambers. Given the increasing urgency of add...
Impact of organic and conventional production systems on mineral, chemical, ant...
Freitas, Daniela; Coelho, Ana; Marques, Ana; Dias, João; Amaral, Olga; Lageiro, Manuela; Simões, ManuelaThe winemaking industry represents one of the most important sectors of the Mediterranean agrifood economy, generating large amounts of solid residues, especially grape pomace. The study aimed to evaluate during two consecutive harvest years the influence of the production system (conventional vs. organic) and cultivar on the mineral, chemical, and antioxidant composition, as well as the colorimetric properties...
Bridging meadows and sheaves
Dias, João; Dinis, Bruno; Macias Marques, PedroWe bridge sheaves of rings over a topological space with common meadows (algebraic structures where the inverse for multiplication is a total operation). More specifically, we show that, given a topological space X, the subclass of pre-meadows with a, coming from the lattice of open sets of X, and the class of presheaves over X are the same structure. Furthermore, we provide a construction that, given a sheaf o...
LINA: an augmented reality social game enhancing sense of belonging among class...
Krammer, Ina; Mittmann, Gloria; Nater, Urs M.; Barnard, Adam; Martins, Diogo; Dias, João; Schrank, Beate; Woodcock, Kate A.Supportive peer relationships are fundamental in the development of well-being. Since early adolescents spend a lot of time at school, especially in their classroom, a sense of belonging among classmates plays a pivotal role for mental health and academic functioning. Programs that enhance sense of belonging among classmates through improving peer relationships in classrooms are rare. Given that early adolescen...
Wieacker-Wolff syndrome - A rare X-linked hereditary disorder
Dias, João; Martins, Cecília; Soares, Ana Rita; Gonçalves-Rocha, Alexandra M; Rocha, FelisbelaWieacker-Wolff syndrome (WWS) is an X-linked disorder caused by a pathogenic mutation in the ZC4H2 gene. It affects both the central and peripheral nervous systems. The authors describe the case of a six-year-old boy with global developmental delay since the age of four months, with marked axial hypotonia. He had a history of bilateral clubfoot, feeding difficulties, and recurrent respiratory infections. Physic...
Towards an enumeration of finite common meadows
Dinis, Bruno; Dias, JoãoCommon meadows are commutative and associative algebraic structures with two operations (addition and multiplication) with additive and multiplicative identities and for which inverses are total. The inverse of zero is an error term a which is absorbent for addition. We study the problem of enumerating all finite common meadows of order n (that is, common meadows with n elements). This problem turns out to be d...
Strolling through common meadows
Dinis, Bruno; Dias, JoãoThis paper establishes a connection between rings, lattices and common meadows. Meadows are commutative and associative algebraic structures with two operations (addition and multiplication) with additive and multiplicative identities and for which inverses are total. Common meadows are meadows that introduce, as the inverse of zero, an error term a which is absorbent for addition. We show that common meadows a...
Impact of different Cynara cardunculus L. extracts on the physicochemical, micr...
Alvarenga, Nuno; Fernandes, Jaime; Fidalgo, Liliana; Santos, Maria Teresa; Dias, João; Gomes, Sandra; Baltazar, T.; Fiates, V.; Conceição , CristinaThis study aimed to evaluate the impact of different Cynara cardunculus L. extracts on the physicochemical, microbial, and sensory properties of PDO Serpa cheese, including moisture content, texture, nitrogen fractions, fatty acid profile, microbial characteristics, and overall acceptance. Cheese samples were produced in two dairies (C and G) with three cardoon coagulants (J, C, and G) and analyzed at the begin...
Gelidium corneum and its solid by-product from agar extraction are sources of h...
Batista, Joana; Lopes, Diana; Neves, Bruna B.; Pais, Ana Rita; Pinho, Marisa; Moreira, Ana S. P.; Conde, Tiago; Bonciarelli, Stefano; Goracci, LauraThe red alga Gelidium corneum is commonly harvested for agar extraction, producing significant biomass residue that remains underutilized. Gelidium corneum and its residue represent promising sources of high-value compounds, including lipid ingredients, encompassing omega-3 and omega-6 polyunsaturated fatty acids, with potential applications in foods and cosmetics. Algae lipids are quite diverse and complex, ho...
PORTRESS – the PORTuguese Reuma.pt registry for Sjögren’S disease
Bandeira, Matilde; Silvério-António, Manuel; Costa, Roberto Pereira da; Lopes, Ana Rita; Santos, Filipe Cunha; Pereira, Paulo J.Aims: Sjögren's disease (SjD) is a complex disease with a wide variety of manifestations and outcomes. We recently created PORTRESS, the Portuguese SjD registry within Reuma.pt. We aim to describe this registry and characterize our national cohort. Methods: We included patients with a clinical diagnosis of SjD, registered in PORTRESS up to November 2023. Demographic, clinical, treatment, and patient-reported ou...
