1. Effect of valve replacement for aortic stenosis on ventricular function
Abstract : Background:Aortic stenosis (AS) is the commonest valve disease in the West. Aortic valve replacement (AVR) remains the only available management for AS and results in improved symptoms and recovery of ventricular functions. READ MORE

2. Aspects on ventilation induced stress and strain on regional and global inflammation in experimental acute respiratory distress syndrome
Abstract : Mechanical ventilation (MV) is a life-saving therapy in acute respiratory distress syndrome (ARDS), a condition that affects 3000 patients/year in Sweden with a mortality rate of about 40%. However, MV may induce or worsen lung injury causing “ventilator-induced lung injury (VILI)”. READ MORE

3. The Plastic Flow Behaviour of Aluminium Alloys Exhibiting Dynamic Strain Ageing
Abstract : The phenomenon known as dynamic strain ageing, abbreviated DSA, has been known since the beginning of last century. It was first discovered as serrations in the load-elongation curve obtained upon deforming specimens of certain alloys in tension. This phenomenon became known as the Portevin-Le Chatelier (PLC) effect. READ MORE

4. Modelling of the Fletcher-Gent effect and obtaining hyperelastic parameters for filled elastomers
Abstract : The strain amplitude dependency , i.e. the Fletcher-Gent effect and Payne effect, and the strain rate dependency of rubber with reinforcing fillers is modelled using a modified boundary surface model and implemented uniaxially. READ MORE

5. High strain rate deformation of Alloy 718
Abstract : Alloy 718 is a high temperature alloy, used where high temperature strength or oxidation resistance is required. As the alloy is precipitate heat treatable it is possible to have a large variety of strength depending on microstructure. READ MORE
