Introduction: Patients suffering from long standing dysphagia need tube feeding through gastrostomy. Nutritional assessment of these patients is challenging and must be supported on objective data, including anthropometric evaluation.Aim: The aim of this study was the evaluation of the usefulness of anthropometry for identifying and grading malnutrition, as part of the initial assessment of patients that underw...
Introduction: In tissues and organs exposed to large pressure amplitude low frequency noise fibrosis occurs in the absence of inflammatory signs, which is thought to be a protective response. In the parotid gland the perivasculo-ductal connective tissue surrounds arteries, veins and the ductal tree. Perivasculo-ductal connective tissue is believed to function as a mechanical stabilizer of the glandular tissue.M...

CONTEXT: Healthcare-associated infection represents the most frequent adverse event during care delivery. Medical advances like percutaneous endoscopic gastrostomy have brought improvement on quality of life to patients but an increased risk of healthcare-associated infection. Predictive risk factors for peristomal wound infection are largely unknown but evidence suggests that antibiotic prophylaxis and prevent...

O presente trabalho avalia a influência dos sedimentos na caracterização das praias, recorrendo ao estudo da praia da Barra, no distrito de Aveiro. Durante o período compreendido entre Outubro de 2010 e Maio de 2011, foram realizadas 33 recolhas semanais de sedimentos, ao longo de cinco pontos pertencentes a um perfil transversal, que incluíram areias emersas e imersas. Paralelamente foram recolhidos dados do c...
A child restraint system, to be certified to NBR 14400 standard, has as one of its main requirements, to reach specific performance levels under impact tests. During its development, the device has to undergo several times such tests, which are expensive, until approval. This study proposes a simplified impact test, not to replace the certification test, but as a preliminary and eliminatory test. The main equip...
Considerando o consumo como o conjunto de processos socioculturais nos quais se realizam a apropriação e os usos dos produtos, este artigo tem por proposta uma análise histórica das principais teorizações sobre esta temática, com destaque às análises que se preocuparam com efeitos de subjetivação advindos da "sociedade de consumo". Apresenta e analisa as primeiras contribuições para esta discussão em Marx e em ...
O projecto de modernos sistemas de engrenamento, para operarem em regimes de grandes potências e elevadas velocidades, recorre cada vez com maior frequência à Concepção Assistida por Computador apoiada em códigos do Método dos Elementos Finitos e do Método dos Elementos Fronteira. A correcta definição da geometria do perfil dos dentes das rodas é fundamental para a credibilidade dos resultados obtidos. A defini...
