1. The Uncemented Cup in Total Hip Arthroplasty : stability, Wear and Osteolysis
Abstract : Background: Artificial hip joint replacement has undergone tremendous development in the past 100 years. In the beginning, complications, such as infection and early loosening, were the rule rather than the exception. Today, complications of any sort are rare during the first decade after the operation.

2. Tunable surfaces : using polyoxoniobates and -tantalates as molecular building blocks
Abstract : This thesis describes and explains the use of aqueous polyoxometalates (POMs), as molecular building blocks in the fabrication of tunable solid-state materials, such as thin films. Microwave irradiation in the synthesis of Nb10, Nb6 and Ta6 is a rapid and efficient alternative to conventional hydrothermal methods, while offering equal – if not greater yields – of product.

3. Me-Si-C (Me= Nb, Ti or Zr) : Nanocomposite and Amorphous Thin Films
Abstract : This thesis investigates thin films of the transition metal carbide systems Ti-Si-C, Nb-Si-C, and Zr-Si-C, deposited at a low substrate temperature (350 °C) with dc magnetron sputtering in an Ar discharge. Both the electrical and mechanical properties of these systems are highly affected by their structure. READ MORE

4. Rules of Thumb and Management of Common Infections in General Practice
Abstract : This thesis deals with problem solving of general practitioners (GPs), which is explored with different methods and from different perspectives. The general aim was to explore and describe rules of thumb and to analyse the management of respiratory and urinary tract infections (RTI and UTI) in general practice in Sweden. READ MORE

5. Nanocomposites for Use in Sliding Electrical Contacts
Abstract : In this thesis nanocomposite materials for use in high performance electrical contacts are tested. Self mating silver as coatings on cupper substrates are the most used material combination in power connectors today. In this work two new concepts were tested. READ MORE
