Piezoelectric co-axial filaments produced by co-extrusion of poly(vinylidene fl...

Documento submetido para revisão pelos pares. A publicar em "Journal of applied polymer science". ISSN 1097-4628. Article first published online: 3 APR 2014 : http://onlinelibrary.wiley.com/doi/10.1002/app.40710/abstract. DOI 10.1002/app.40710. ; The development of new thermoplastic polymer-based piezoelectric sensors with filament geometry is described. These filaments are appropriate for integration into tex...

Processing and electrical response of fully polymer piezoelectric filaments for...

This paper describes the production and characterization of novel geometries for piezoelectric products with a large potential in the design and implementation of flexible sensors produced at low cost and high rates. In particular, the filament geometry, appropriate for integration into textiles, is analyzed. Piezoelectric filaments producing electrical signals under bending or traction stress, thus acting as m...

Ryanodine myopathies without central cores-clinical, histopathologic, and genet...

BACKGROUND: Mutations in ryanodine receptor 1 gene (RYR1) are frequent causes of myopathies. They classically present with central core disease; however, clinical variability and histopathologic overlap are being increasingly recognized. PATIENTS: Patient 1 is a 15-year-old girl with mild proximal, four-limb weakness from age 5, presenting with a progressive scoliosis starting at age 10. Patient 2 is an 18-yea...

Dramatic recovery after IV thrombolysis in anterior circulation ischemic stroke...

BACKGROUND AND PURPOSE: Dramatic recovery (DR) after thrombolysis is dependent of vessel recanalization and is predictive of favorable clinical outcome. Successful recanalization is not equivalent to DR. Our objective was to assess its frequency and evaluate clinical and biochemical predictors and their prognosis. METHODS: We analyzed prospectively registered data from January 2007 to September 2012. All patie...

Traumatic brain injury in portugal: trends in hospital admissions from 2000 to ...

Introduction: Traumatic brain injury has a considerable socio-economic impact, being a major cause of morbi-mortality, often with permanent disability. We sought to characterize health resource utilization of adult traumatic brain injury patients in Portugal between 2000 and 2010. Material and Methods: Retrospective study of medical records of adult patients with ICD9 diagnostic code of traumatic brain injury i...

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...

Museu da Pessoa – arquitectura

É conhecido o extremo valor patrimonial e sociológico das Histórias de Vida. No entanto, apesar do encanto irresistíveldas histórias, trata-se de um património em rápido desaparecimento.O Museu da Pessoa é um arquivo fundamentalmente acessível pela Internet, que apresenta um conjunto de especificidades:

Blistering of W–Ta composites at different irradiation energies

Pure tungsten and tantalum plates and tungsten–tantalum composites produced via mechanical alloying and spark plasma sintering were bombarded with He+ and D+ energetic ion beams and deuterium plasmas. The aim of this experiment is to study the effects caused by individual helium and deuterium exposures and to evidence that the modifications induced in the composites at different irradiation energies could be fo...

Effects of helium and deuterium irradiation on SPS sintered W–Ta composites at ...

Energetic He+ and D+ ions were implanted into different W–Ta composites in order to investigate their stability under helium and deuterium irradiation. The results were compared with morphological and chemical modifications arising from exposure of pure W and Ta. Special attention was given to tantalum hydride (Ta2H)formation due to its implications for tritium inventory. Three W–Ta composites with 10 and 20 at...
