Cruz, Simão; Cruz, Simão; Matos, Anabela; Braz, Luis; Falcão de Campos, Catarina; Cerqueira, Joao; Medeiros, Luisa; Santos, Ernestina; Santos, Luis

A miastenia gravis é uma doença autoimune da junção neuromuscular, cuja fisiopatologia consiste na produção de anticorpos patogénicos, mais frequentemente dirigidos contra o recetor nicotínico da acetilcolina e, mais raramente, contra a cinase específica do músculo. Outros elementos fisiopatológicos importantes incluem a cascata do complemento e as linhagens linfocitárias B e T. O diagnóstico assenta em fraquez...


Sustainable Aviation Fuels and their impact in commercial airport operation

Magalhães, Leandro; Santos, Luis; Ferreira, Ana Filipa; Silva, André Resende Rodrigues da

With global air traffic projected to grow annually by approximately 3.8%, the aviation sector faces increasing pressure to implement effective strategies for mitigating its environmental impact, particularly with respect to greenhouse gas emissions. Sustainable Aviation Fuels represent a critical pathway for decarbonizing aviation by offering a lower-emission alternative to conventional jet fuels. This study ev...

Efficacy of Pelvic Rehabilitation in the Person with Fecal Incontinence after c...

Martins, Rosa Maria Lopes; Fonseca, Irene; Santos, Luis; Carvalho, Nélia

Introduction: Fecal incontinence (FI) has deleterious effects on patients, resulting in discomfort, anxiety, embarrassment and profound changes in their quality of life. There is tenuous evidence that these effects can be mitigated with the implementation of pelvic rehabilitation programs. Objective: To evaluate the effectiveness of implementing pelvic rehabilitation programs in people with fecal incontinence a...

Silva, Julio; Santos, Luis; Lopes, Vasco

O turismo de natureza é uma das indústrias que mais cresceu no mundo desde o início do século. Este crescimento é raramente acompanhado pelos sistemas de gestão de áreas naturais que lutam contra o número crescente de turistas, falta de infraestruturas, informação e organização. Uma das soluções adotadas por muitas áreas naturais é a adoção de classificações adicionais, tais como reservas de biosfera, Ramsar, N...


Bridging Culture, Tourism, and Literature: The Short Videos of Saramago's Small...

Silva, Julio; Santos, Luis; Silva, Manuela; Cordeiro, João; Carmo, Ana do; Romana, Maria Barras; Caetano Domingos, Susana Isabel

A arte, conforme definida por Leo Tolstoi (2013), é a atividade pela qual uma pessoa, tendo experimentado uma emoção, transmite-a intencionalmente a outros. A forte ligação entre o enquadramento geográfico e experiências do autor, despoleta a imaginação do leitor e a vontade de viver na primeira pessoa as experiências. Algumas obras literárias e autores que estimularam os leitores a viajar, por exemplo Stratfor...


Environmental Factors Affecting the Efficiency of Water Reservoir Restoration U...

Mazur, Robert; Jakubiak, Mateusz; Santos, Luis

Aquatic ecosystems are often subject to degradation due to various environmental stressors. The accumulation of an organic sediment layer causes shallowing, algal blooms, and hypertrophy in water reservoirs. The processes of overgrowth and shallowing lead to a reduction in the ecosystem services provided by the reservoir as well as potentially causing the disappearance of the water body. To address these challe...


Integrated Analysis of Tourism Offer from Golegã and Torres Novas Municipalities

Santos, Luis; Silva, Julio; Lopes, Eunice R.; Simões, Jorge

Post pandemic tourism observes a worldwide consumer choice shift from the traditional sun and beach to adventure and nature-based tourism. While interesting for many countries such as Portugal where interior regions observe abandonment and deteriorating economic development, this new economic boost presents unforeseen risk. Both Municipalities hold similar potential and diversity of assets, from cultural festiv...


Dynamics of a gyrostat satellite with the vector of gyrostatic moment tangent t...

Morais, Renato; Santos, Luis; Silva, André; Melicio, Rui

In this paper, a gyrostat satellite in a circular orbit with its gyrostatic moment tangent to the orbital plane and collinear with the orbital speed is studied regarding its equilibria, bifurcation of equilibria, and asymptotic stability conditions. In the general case, where any gyrostat angular momentum is aligned with any of the orbital coordinate frames, interesting results arose regarding its equilibria bi...


Short-Term Consequences of Asteroid Impacts into the Ocean: A Portuguese Case S...

Morais, Renato; Santos, Luis; Silva, André; Melicio, Rui

Asteroid impacts are a proven global threat, meaning that any location on Earth might be a subject to their consequences. Such collisions are not likely in any person’s lifetime, but their aftermath could be catastrophic. As Earth’s surface is mostly water, a water impact is more probable than a ground impact, and tsunami waves could pose a significant threat. This study expands the knowledge about asteroid imp...


Corrosion behaviour in artificial saliva of medical grade SS316L sputter-coated...

Frois, António; Faia, Pedro; Santos, Luis; Santos, Ana; Louro, C.

ABSTRACT: Hydrogenated amorphous carbon (a-C:H) top layer was deposited onto 316L medical grade stainless steel by reactive magnetron sputtering with two types of interlayers, based on Cr and Ti. The goal was to evaluate the effect of the adhesion-promoting layers on the overall coating/substrate system. After the immersion test in acidic artificial saliva, no surface signs of corrosion were detected. However, ...
