2. 1. The Uncemented Cup in Total Hip Arthroplasty : stability, Wear and Osteolysis

   Author : Volker T C Otten; Sead Crnalic; Kjell G Nilsson; André Stark; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   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.

4. 2. Tunable surfaces : using polyoxoniobates and -tantalates as molecular building blocks

   Author : Mark Rambaran; C. André Ohlin; Jean-Francois Boily; Mari-Ann Einarsrud; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   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.

5. 3. Me-Si-C (Me= Nb, Ti or Zr) : Nanocomposite and Amorphous Thin Films

   Author : Olof Tengstrand; Lars Hultman; Per Eklund; Benny André; Linköpings universitet; []
   Keywords : ;

   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

6. 4. Rules of Thumb and Management of Common Infections in General Practice

   Author : Malin André; Norbert Donner-Banzhoff; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; General practice; rules of thumb; decision making; respiratory tract infections; urinary tract infections; diagnostic tests; C-reactive protein test; antibiotic prescribing; Urology and andrology; Urologi och andrologi;

   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

7. 5. Nanocomposites for Use in Sliding Electrical Contacts

   Author : Benny André; Urban Wiklund; Staffan Jacobson; Kenneth Holmberg; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tribology; materials science; Materialvetenskap; Materials Science; Engineering Science with specialization in Materials Science; Teknisk fysik med inriktning mot materialvetenskap; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

   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
