Wildfire behaviour depends on complex interactions between fuels, topography, and weather over a wide range of scales, being important for fire research and management applications. To allow for significant progress towards better fire management, the operational and research communities require detailed open data on observed wildfire behaviour. Here, we present the Portuguese Large Wildfire Spread database (PT...
Melt extrusion-based additive manufacturing (ME-AM) is a promising technique to fabricate porous scaffolds for tissue engineering applications.However,most synthetic semicrystalline polymers do not possess the intrinsic biological activity required to control cell fate. Grafting of biomolecules on polymeric surfaces of AM scaffolds enhances the bioactivity of a construct; however, there are limited strategies a...
O presente trabalho surge no âmbito de um estudo em que foram desenvolvidos varões de compósito entrançados (BCRs) piezoresistivos através da incorporação de um filamento de fibra de vidro impregnado com nanotubos de carbono (CNTs). Diferentes concentrações mássicas de CNTs [0%, 0,5%, 1%, 1,5%, 2% e 2,5%] foram dispersas em formulações poliméricas de resina epóxi e ácido polilático (PLA). Estas formulações fora...
Simulation of vegetation fires very often resorts to fire-behavior models that need fuel models as input. The lack of fuel models is a common problem for researchers and fire managers because its quality depends on the quality/availability of data. In this study we present a method that combines expert- and research-based knowledge with several sources of data (e.g. satellite and fieldwork) to produce customize...
The low prevalence of European paediatric transplanted patients and scarcity of resources and expertise led to the need for a multidisciplinary network able to improve the quality of life of paediatric patients and families requiring a solid organ or haematopoietic stem cell transplantation. The European Reference Network (ERN) TransplantChild is one of the 24 ERNs established in a European legal framework to i...
This work compares two polyureas used in blast mitigation through a chemical and mechanical characterization, by FTIR and tensile tests, respectively. The FTIR test performed allowed to identify some differences regarding the content of hard domains of the polyureas. The tensile tests carried out allowed to analyse the influence of the content of hard domains of the polyureas on its mechanical properties. In th...
The present work intends to evaluate the influence of the impregnation of different polymeric materials in the energy absorption of reinforced composites with three-dimensional auxetic meshes. In this sense, composites were developed with two different thermosetting polymeric matrices, namely polyurethane and epoxy resins, which were applied on one and both sides of the reinforcement mesh. As main results, it w...
This work compares the influence of different thermoplastic polymer/waste wood dust ratios on the mechanical and thermal properties of composite materials. Moreover, the effect of a coupling agent incorporation, namely maleic anhydride polypropylene (MAPP), to promote better adhesion between both components, on these properties was evaluated. The composite materials were obtained by compression moulding process...
ANCA-positive systemic vasculitides, rare in paediatric age, present multiorganic involvement. A female teenager presented with a history of subglottic stenosis diagnosed at the age of 12. From the investigation carried out, we highlight hematoproteinuria and negative ANCAs. At 15 years old, she was admitted for gastrointestinal symptoms and respiratory distress. She presented poor peripheral perfusion, pulmona...
