Natural products as health promoters
Barros, Lillian; Heleno, Sandrina A.; Prieto Lage, Miguel A.Given the recognized health benefits of natural matrices, the scientific community, in strong collaboration with the industry, has been exploiting natural resources in search of bioactive molecules. These bioactive molecules, such as polyphenols, vitamins, and carotenoids, are responsible for the health-promoting effects of plants, mushrooms, fruits, etc. The main bioactive attributes are related to their antio...
Desenvolvimento e aplicação de sistema de baixo custo na avaliação de parâmetro...
Prestes, Matheus de Oliveira; Feliciano, Manuel; Frare, Laercio; Alves, Rafaela Cruz; Igrejas, GetúlioA associação das características físicas, químicas e biológicas observadas nas atmosferas interiores e a integridade física dos ocupantes têm-se tornado um objeto de estudo bastante comum nas últimas décadas, de forma a evidenciar relações significativas entre estes aspetos, com especial ênfase para a os efeitos da fração respirável do material particulado (PM2,5) e a saúde humana. Uma compreensão sistemática d...
Simulations of stirred yoghurt processing in plate heat exchangers. Part II: Th...
Afonso, Isabel M.; Fernandes, Carla S.; Maia, João M.; Melo, Luis F.Thermal processing and manufacturing in the food industry involves heating and cooling of highly viscous fluids. In general, these fluids exhibit complex flow patterns and are dependent on temperature, shear rate, duration of shear and elastic properties. Since the main factor limiting heat transfer is the viscous behaviour of the fluids, models that can capture this are of major interest to optimize heat excha...
Numerical analysis of piping elbows for in-plane bending and internal pressure
Fonseca, E.M.M.; Melo, F.J.M.Q. de; Oliveira, C.A.M deThis work presents the development of two different finite piping elbow elements with two nodal tubular sections for mechanical analysis. The formulation is based on thin shell displacement theory, where the displacement is based on high-order polynomial or trigonometric functions for rigid-beam displacement, and uses Fourier series to model warping and ovalization phenomena of cross-tubular section. To model t...
Seasonal variation in reproductive measures of tropical Roseate Terns Sterna do...
Ramos, JaimeSeasonal variation in egg-laying, egg size, hatching success, hatchling mass, fledging success and chick growth of Roseate Terns Sterna dougallii breeding on Aride Island (Seychelles), Indian Ocean, were studied in 1997 and 1998. I investigated to what extent two patterns, common in a range of species, were followed by tropical Roseate Terns: (a) seasonal decrease in clutch size, egg size and breeding success a...

Wind energy in Tunisia: opportunities for integration of storage technologies
Ayed, YasmineThis thesis has been conducted to couple hourly wind data of six different measurement station in Tunisia provided from Tunisian meteorological stations to the electricity consumption in a timeline fashion. The idea is to evaluate the wind potential for a few locations around Tunisia using Weibull distribution and Meteorological methods. The latent of wind power was statistically investigated including the aver...
The Aging Curve: How Age Affects Physical Performance in Elite Football
Branquinho, Luís; França, Elias; Titton, Adriano; Barros, Luís Fernando Leite; Campos, Pedro; Marques, Felipe O.; Glória, Igor Phillip dos SantosBackground: In elite football, understanding how age impacts players’ physical performance is essential for optimizing training, career longevity, and team management. Objectives: This study aimed to compare variations in physical capabilities of professional football players by chronological age and identify peak performance ages. Methods: Data from 5203 match performances across 351 official games were analyz...
Fire dynamics in open compartments
Piloto, P.A.G.; Possoli, Ketlen; Junior, Luiz C.M.; Nechab, Khadouma; Benarous, AbdallahWith the aim to increase fíre safety in open compartments, such as open car parks, some correlative models were used to test the ability to recover both dynamics and thermal characteristics ofa ceiling-jet flow. The flow occurs when the fire plume impinges the ceiling and develops in the radial direction ofthe fire axis. Both temperature and velocíty predictions decisive for sprinklers positioning, fire alarms ...
Ação social no Ensino Superior face aos objetivos de desenvolvimento sustentáve...
Praça, Lídia GalvãoO ano de 2015 fica associado ao lançamento da Agenda 2030 para o Desenvolvimento Sustentável, adotada por todos os países integrantes das Nações Unidas (ONU), cujo intuito foi definir prioridades e aspirações para o desenvolvimento sustentável global. Nela se incluem 17 Objetivos de Desenvolvimento Sustentável (ODS), cada um com várias metas para a respetiva concretização. De acordo com o Conselho Empresarial p...
