16. Wear characteristics of materials for artificial hip joints
Abstract : Total hip prostheses have succeeded in significantly improving the quality of life of millions of patients worldwide. Ultra high molecular weight polyethylene (UHMWPE) has been widely and successfully used as a bearing material in orthopaedic prostheses since the 1960s. READ MORE

17. Assessment of acetabular cup wear with computed tomography and influence of surface roughness on wear of materials for hip prostheses
Abstract : Over one million hip prostheses are implanted in patients worldwide each year and the need is increasing as the patient group of younger and more active patients is increasing. Many parameters affect the longevity of the implant, where aseptic loosening caused by wear debris is the most common reason for revision. READ MORE

18. Particle emissions from car brakes : The influence of contact conditions on the pad-to-rotor interface
Abstract : Due to their adverse health effects emissions have been regulated for over three decades. Brake wear particulate matter is the most important non-exhaust source, however current knowledge is mainly limited to observational studies. READ MORE

19. Computed Tomography of Acetabular Cup Wear and Effect of Surface Roughness on Wear and Oxidation of UHMWPE Hip Prostheses
Abstract : Aseptic loosening is the most common complication in total hip replacement (5- 10% at 10 years follow up). The magnitude of the problem is illustrated by the fact that about one million hip prostheses are implanted worldwide each year. READ MORE

20. Ultrahigh-Voltage Silicon Carbide Device Performance, Requirements, and Limitations in High-Power Applications
Abstract : The increased awareness of the on-going climate change accelerates the electric energy system transformation from fossil-fueled power sources towards systems with larger portions of renewable energy sources. Moreover, the grid infrastructure requires reinforcements to cope with increasing electrical energy demand. READ MORE
