1. On Active Suspension in Rail Vehicles
Sammanfattning : The topic of this PhD thesis is active suspension in rail vehicles whichis usually realized through sensors, controllers and actuation components.A well established example of an active suspension is the tiltingcontrol system used to tilt the carbody in curves to reduce centrifugalacceleration felt by passengers.

2. 3D Magnetic Photonic Crystals : Synthesis and Characterization
Sammanfattning : This thesis presents the synthesis methods and the characterizations of magnetic Fe3O4 nanoparticles, silica spheres with Fe3O4 nanoparticles embedded, and three dimensional magnetic photonic crystals (MPCs) prepared from the spheres. The structure, material composition, magnetic and optical properties, photonic band gaps (PBGs), as well as how these properties depend on the concentration of the magnetic nanoparticles, are investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), vibrating sample magnetometer (VSM), superconducting quantum interference device (SQUID), Faraday rotation (FR) and optical spectrophotometers.

3. Novel Insight into Thymidylate Kinase: Biochemical Characterization of the Human and Zebrafish Enzymes
Sammanfattning : Deoxythymidine triphosphate (dTTP or T) is one of the four building blocks for DNA. In dTTP synthesis, the catalysis of dTMP to dTDP, is mediated by one known enzyme only: Thymidylate kinase (TMPK, EC 2.7.4. LÄS MER
