Thermo-Mechanical Behaviour of Flax-Fibre Reinforced Epoxy Laminates for Industrial Applications

2015

The present work describes the experimental mechanical characterisation of a natural flax fibre reinforced epoxy polymer composite. A commercial plain woven quasi-unidirectional flax fabric with spun-twisted yarns is employed in particular, as well as unidirectional composite panels manufactured with three techniques: hand-lay-up, vacuum bagging and resin infusion. The stiffness and strength behaviours are investigated under both monotonic and low-cycle fatigue loadings. The analysed material has, in particular, shown a typical bilinear behaviour under pure traction, with a knee yield point occurring at a rather low stress value, after which the material tensile stiffness is significantly r…

Decompressive Craniectomy Improves QTc Interval in Traumatic Brain Injury Patients

2020

Background: Traumatic brain injury (TBI) is commonly associated with cardiac dysfunction, which may be reflected by abnormal electrocardiograms (ECG) and/or contractility. TBI-related cardiac disorders depend on the type of cerebral injury, the region of brain damage and the severity of the intracranial hypertension. Decompressive craniectomy (DC) is commonly used to reduce intra-cranial hypertension (ICH). Although DC decreases ICH rapidly, its effect on ECG has not been systematically studied. The aim of this study was to analyze the changes in ECG in patients undergoing DC. Methods: Adult patients without previously known cardiac diseases treated for isolated TBI with DC were studied. EC…

The effects on riding performance using active vs passive recovery during a simulated motocross race

2017

Aleix Ollé Casanovas. 2017. The effects on riding performance using active vs passive recovery during a simulated motocross race. University of Jyväskylä. 53p. The aim of the present study was to examine the effect of active and passive recovery methods in order to improve physical performance between motocross races. Exercise induced muscle damage post motocross racing was assessed as well. Participants performed 2 races of 30 minutes with one hour break in between. During the break they performed either active or passive recovery protocols. Specific motocross performance outcomes and athlete’s physical conditions were measured during, and before and after every motocross race. Lap times (…

Progressive non-linear damage of variable angle tow composite plates by a Ritz approach

2022

In this work a Ritz model for progressive non-linear damage analysis of variable angle tow composite plates is presented. The damage is treated in the framework of continuum damage mechanics and its evolution is based on a linear softening law with which four damage indices are computed for degrading the mechanical properties of the material. A set of analyses have been carried out to investigate how damage evolves in VAT composite plates under progressive loading.

Neuronal effects of Sugammadex in combination with Rocuronium or Vecuronium.

2017

Rocuronium (ROC) and Vecuronium (VEC) are the most currently used steroidal non-depolarizing neuromuscular blocking (MNB) agents. Sugammadex (SUG) rapidly reverses steroidal NMB agents after anaesthesia. The present study was conducted in order to evaluate neuronal effects of SUG alone and in combination with both ROC and VEC. Using MTT, CASP-3 activity and Western-blot we determined the toxicity of SUG, ROC or VEC in neurons in primary culture. SUG induces apoptosis/necrosis in neurons in primary culture and increases cytochrome C (CytC), apoptosis-inducing factor (AIF), Smac/Diablo and Caspase 3 (CASP-3) protein expression. Our results also demonstrated that both ROC and VEC prevent these…

Electrical conductivity of glass fiber-reinforced plastic with nanomodified matrix for damage diagnostic

2021

The electrical conductivity of glass fiber-reinforced plastic (GFRP) with epoxy matrix modified by multiwall carbon nanotubes (MWCNT) was studied. The electrical conductivity of nanomodified lamina and multi-layered GFRP was investigated on several levels using a structural approach. Components of the electrical conductivity tensor for unidirectional-reinforced monolayer were calculated similarly as in micromechanics using the conductivity of the nanomodified matrix. The electrical conductivity of multilayer composite was calculated using laminate theory and compared with values measured experimentally for various fiber orientation angles. Calculated and experimental data were in good agree…
