Study of fatigue crack propagation on modified CT specimens under variable ampl...
Santos, B.; Infante, Virginia; Barros, T.; Miguel Gomes Simões Baptista, RicardoThis study focuses on predicting fatigue crack paths and fatigue life in modified compact tension specimens, under mixed mode and variable amplitude loading conditions, using Machine Learning techniques. Mixed-mode conditions were induced by using specimens that incorporated holes with different radii and center coordinates. Initially, multiple Finite Element Method (FEM) simulations were conducted to determine...
Respiração lenta abdominal ióguica e variabilidade da frequência cardíaca em cr...
Mercê, Cristiana; Catela, David; Borges, A.; Santos, B.; Pereira, M.; Gomes, M.; Esperança, R.; Santos, Júlia; Oliveira, JoanaA variabilidade da frequência cardíaca (VFC) é um indicador de saúde. Uma respiração lenta pode propiciar o seu aumento. Fomos verificar se crianças de 7 e 8 anos conseguiriam executar uma respiração predominantemente diafragmática, e qual o seu efeito agudo em parâmetros da VFC. Ocorreu uma redução significativa da frequência respiratória e um aumento da VFC. As crianças conseguiram executar esta técnica respi...
Importância da citologia na deteção de lesões do endométrio
Santos, B.; Oliveira, C.; Ramos, S.; Gomes, N.; Oliveira, Daniel; Silva, A. S.; Adriano, A.; Luís, A.; Mendonça, PaulaO presente estudo reporta a citologia de uma mulher de 66 anos, que apresenta um epitélio atrófico com fundo inflamatório. Identificaram-se agregados tridimensionais de células glandulares com sobreposição celular, anisocariose, aumento nuclear, hipercromasia moderada, presença de nucléolos e cromatina grosseira, irregularmente distribuída. O diagnóstico citológico foi de células glandulares atípicas sem outra ...
Bone remodelling of the humerus after a resurfacing and a stemless shoulder art...
Santos, B.; Quental, Carlos; Folgado, João; Sarmento, Marco; Monteiro, JacintoBackground: New implant designs, such as resurfacing and stemless implants, have been developed to improve the long-term outcomes of the shoulder arthroplasty. However, it is not yet fully understood if their influence on the bone load distribution can compromise the long-term stability of the implant due to bone mass changes. Using three-dimensional finite element models, the aim of the present study was to an...
Meeting in Viena 30 years after Ottawa: QuoVadis health promotion?
Saboga-Nunes, L.A.; Costa, A.; Padua, F.; Amann, G. Von; Figueiras, M.J.; Carvalho, Graça Simões de; Martins, R.; Caldas-Almeida, T.; Stock, C.This study explores experts’ and practitioners’ opinions on the current trends that Health promotion (HP) faces in Portugal. The survey was carried out with several health stakeholders and results showed that HP is not well developed and a deeper reflection on the issue is needed.
Meeting in Vienna 30 years after Ottawa: QuoVadis health promotion?
Saboga-Nunes, L.A.; Costa, A.; de Pádua, F.; von Amann, G.; Figueiras, M.J.; Carvalho, G.S.; Martins, R.; Caldas-Almeida, T.; Stock, C.; Milczarski, A.Objetives: - To explore the opinions of health promotion researchers and practitioners on the current relevance of health promotion principles: - To study how the Ottawa Charter and Health Promotion concepts and practices have been applied; - To answer the questions: Is the Charter known and still relevant in today’s context? ; Where does Health Promotion stand?
Biophysical probing of Spartina maritima photo-system II changes during prolong...
Duarte, B.; Santos, B.; Marques, J. C.; Caçador, I.Submergence is one of the major constrains affecting wetland plants, with inevitable impacts on their physiology and productivity. Global warming as a driving force of sea level rise, tend to increase the submersion periods duration. Photosynthesis biophysical probing arise as an important tool to understand the energetics underlying plant feedback to these constrains. As in previous studies with Spartina marit...
Perforated duodenal diverticulum: Surgical treatment and literature review
Costa Simões, V.; Santos, B.; Magalhães, S.; Faria, G.; Sousa Silva, D.; Davide, J.Duodenum is the second most frequent location for a diverticulum in the digestive tract. Complications are rare and perforation was only reported in less than 200 cases. PRESENTATION OF CASE: A 79-year-old female was admitted to Emergency Department with abdominal pain and vomiting for the last 24h. A CT scan was performed and moderated extra-luminal air was identified. During surgery a fourth portion perforate...
