Introdução – A análise da forma ou morfometria de estruturas anatómicas, como o trato vocal, pode ser efetuada a partir de imagens bidimensionais (2D) como de aquisições volumétricas (3D) de ressonância magnética (RM). Esta técnica de imagem tem vindo a ter uma utilização crescente no estudo da produção da fala. Objetivos – Demonstrar como pode ser efetuada a morfometria do trato vocal a partir da imagem por re...
This paper describes the work developed in the final project of the degree in Electronics and Telecommunications Engineering, at Aveiro University in the domain of laboratory automation. Here are shown some final applications developed with the programming tool of National InstrumentsTM – LabVIEW, such as Pin/Pout, I/V and I/P for device characterisation. ; Nesta comunica&cc...
Improvement of food safety is a very important issue, and is on the basis of production and application of new/modified food contact surfaces. Titanium dioxide (TiO2) and, more recently, nitrogen-doped titanium dioxide (N-TiO2) coatings are among the possible forms to enhance food contact surfaces performance in terms of higher hygiene and easier sanitation. In this context, the present work aimed at evaluating...
Resumo O objetivo do presente trabalho é estudar o relacionamento entre os atributos do solo conteúdo de fósforo, potencial hidrogeniônico e densidade do solo com a produtividade da soja. As amostras foram coletadas em um Latossolo Vermelho, em área localizada no município de Braganey-PR, no Paraná, cultivada com soja (Glycine Max L). Na área experimental foram demarcados 84 elementos amostrais ao l...
Santo André is an enclosed brackish water coastal lagoon with temporary connections to the sea by a man-made channel. The exchange and mixture of saltwater and freshwater is irregular and the lagoon may show daily and seasonal fluctuations, but also long-term variation. Different benthic communities may be present along the annual cycle according to the magnitude of episodic freshwater and sea water inputs. In ...
INTRODUÇÃO: A presença de quistos renais na criança é rara, merecendo uma avaliação criteriosa. De um vasto leque de doenças renais e sistémicas que podem cursar com quistos renais na infância, destacam-se, por serem mais frequentes, as doenças renais poliquísticas de transmissão autossómica recessiva e dominante, o rim displásico multiquístico e a esclerose tuberosa. A ecografia é o método imagiológico de esco...
O documento em anexo encontra-se na versão post-print (versão corrigida pelo editor). ; Introduction: Atypical ankle patterns of muscle activity during gait are commonly reported in patients with stroke. These findings can be due to changes between tibialis anterior (TA) and soleus (SOL) coactivation mechanisms. Objective: To compare the electromyographic activity (EMGa) of SOL and TA muscles and antagonist co...
O documento em anexo encontra-se na versão post-print (versão corrigida pelo editor). ; Introduction: The beginning of the movement sequence from standing to sitting requires the modulation of plantar flexors activity, including soleus muscle (SOL), to allow the forward translation of the tibia in relation to the foot, preserving its antigravity function. Purpose: To analyze the SOL activity during the initial...
Purpose: To quantify the effect of unstable shoe wearing on muscle activity and haemodynamic response during standing. Methods: Thirty volunteers were divided into 2 groups: the experimental group wore an unstable shoe for 8 weeks, while the control group used a conventional shoe for the same period. Muscle activity of the medial gastrocnemius, tibialis anterior, rectus femoris and biceps femoris and venous cir...
Non-Hodgkin lymphoma (NHL) has been associated with immunological defects, chronic inflammatory and autoimmune conditions. Given the link between immune dysfunction and NHL, genetic variants in toll-like receptors (TLRs) have been regarded as potential predictive factors of susceptibility to NHL. Adequate anti-tumoral responses are known to depend on TLR9 function, such that the use of its synthetic ligand is b...
