Protective fibrous structures based on cellulose fibers functionalized with met...
Araújo, Joana Carolina Carvalho; Silva, Pedro M.; Cerqueira, Miguel A.; Teixeira, Maria Pilar Araújo; Tira-Picos, Vânia; Neto, PedroThis work aims to develop a bio-based fibrous material that is able to adsorb and degrade chemical and biological hazardous agents. Thus, cellulosic fabrics (flax) were functionalized with chitosan (CS) and poly(ethylene oxide) (PEO) electrospun nanofibers doped with titanium dioxide (TiO2) and cerium dioxide (CeO2) nanoparticles (NPs). The electrospray deposition of these NPs was also tested. The TiO2 NPs were...
Development of functional foods: consumer acceptance of resveratrol-loaded crac...
Silva, Pedro M.; Cerqueira, Miguel A.; Pastrana, Lorenzo; Coimbra, Manuel A.; Vicente, A. A.; Van Bockstaele, Filip; Tzompa-Sosa, DaylanMicro-nano encapsulation can be impactful in flavour masking of bioactives, and it has the potential to be used in the development of functional food ingredients. This work aimed to develop functional foods using emulsified resveratrol, assessing the impact of resveratrol addition and its consumer acceptance. Resveratrol-loaded emulsions were produced through high-speed homogenization/ultrasonication. Functiona...
A hybrid bi-objective optimization approach for joint determination of safety s...
Silva, Pedro M.; Gonçalves, João N. C.; Martins, Tiago M.; Marques, Luís C.; Oliveira, Miguel; Reis, Marcelo I.; Araújo, Luís; Correia, DanielaIn material requirements planning (MRP) systems, safety stock and safety time are two well-known inventory buffering strategies to protect against supply and demand uncertainties. While the role of safety stocks in coping with uncertainty is well studied, safety time has received only scarce attention in the supply chain management literature. Particularly, most previous operations research models have typicall...
Profiling persistent asthma phenotypes in adolescents: A longitudinal diagnosti...
Amaral, Rita; Jácome, Cristina; Almeida, Rute; Pereira, Ana M.; Alves-Correia, Magna; Mendes, Sandra; Rodrigues, José C.; Carvalho, Joana; Araújo, LuísWe aimed to identify persistent asthma phenotypes among adolescents and to evaluate longitudinally asthma-related outcomes across phenotypes. Adolescents (13–17 years) from the prospective, observational, and multicenter INSPIRERS studies, conducted in Portugal and Spain, were included (n = 162). Latent class analysis was applied to demographic, environmental, and clinical variables, collected at a baseline med...
Aplicabilidade de métodos de estudo da composição de betão auto-compactável (BAC)
Silva, Pedro M.; De Brito, Jorge; Costa, João B.O presente artigo tem como objectivo apresentar os resultados obtidos na campanha experimental para o estudo de verificação da aplicabilidade técnica de dois métodos de cálculo de composição de betão auto-compactável - BAC - propostos por investigadores nacionais em trabalhos anteriores. Com o referido estudo, pretendeu-se, através dos métodos em análise, identificar o método que permite de um modo mais simples...
