Additive Manufacturing of Continuous Fibre Reinforced Composites: Process, Characterisation, Modelling, and Sustainability

Advanced Engineering Materials, EarlyView.
Additive manufacturing provides precise control over the placement of continuous fibres within polymer matrices, enabling customised mechanical performance in composite components. This article explores processing strategies, mechanical testing, and modelling approaches for additive manufactured continuous fibre‐reinforced composites.

Left ventricular assessment in patients with mucopolysaccharidosis using conventional echocardiography and myocardial deformation by two‐dimensional speckle‐tracking method

Jornal de Pediatria (Versão em Português), 2019
Objective: Mucopolysaccharidosis is a rare genetic disease characterized by the intralysosomal deposition of glycosaminoglycans. Cardiovascular impairment is a common feature.

Targeting Myocardial Mechanics in Children and Adolescents with Obesity and Non-Elevated Blood Pressure: A Meta-Regression Study

Diseases
Background/Objectives: Although global longitudinal strain (GLS) appears more sensitive than the ejection fraction in uncovering subtle left ventricular (LV) dysfunction, evidence of impaired LV mechanics in children/adolescents with obesity, independent

Spectrum of myocardial involvement in patients with COVID-19 – An echocardiography study [PDF]

Journal of Cardiovascular and Thoracic Research
Introduction: Covid-19 patients can have both regional and global ventricular dysfunction. We aim to study the spectrum of myocardial involvement in Covid-19 patients on echocardiography.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

The influence of material anisotropy and spiral welding on tensile strain capacity of spiral welded pipes [PDF]

, 2015
The longitudinal strain capacity of spiral welded pipelines displays to some extents unexplained behaviour. Therefore, they are not (yet) used extensively in offshore applications and harsh conditions, demanding a strain based design. An important factor

Global longitudinal strain changes during hemorrhagic shock: An experimental study

Turkish Journal of Emergency Medicine, 2020
OBJECTIVES: Global longitudinal strain (GLS) appears sensitive and reproducible to identify left ventricular systolic dysfunction. The main objective was to analyze the GLS changes in an anesthetized-piglet model of controlled hemorrhagic shock (HS). The secondary objective was to evaluate if GLS changes was different depending

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

Advanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...
