3. 2. Housing, labour market conditions and regional migration

   Författare :Hans Jonsson; Lindh Thomas; Matz Dahlberg; Linnéuniversitetet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; employment; mobility; housing tenure; matching efficiency; Economics; Nationalekonomi;

   Sammanfattning : Essay 1: Swedish micro and macro data on internal migration indicate that home-owners on average have a higher propensity to migrate to other labour market areas in response to higher unemployment and job vacancy rates than renters and tenant-owners. This is evidence that owning your home does not constrain labour mobility across labour market areas in comparison to other forms of housing tenure. LÄS MER

4. 3. Turbulent Forced Convection Air Cooling of Electronics with Heat Sinks Under Flow Bypass Conditions

   Författare :Hans Jonsson; KTH; []
   Nyckelord :forced convection; heat transfer; pressure drop; turbulent; air cooling; bypass; plate; strip; pin; fin; heat sink; electronics; experimental; numerical; CFD; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Air cooling is still the dominant method for dissipating theheat produced by electronic components. In a typical electronicdevice, the components are situated on a Printed Circuit Board(PCB). For most applications natural convection is sufficientto cool the components. LÄS MER

7. 5. Safety and biological aspects of present techniques of haemodialysis

   Författare :Per Jonsson; Hans Dietrich Polaschegg; Umeå universitet; []
   Nyckelord :haemodialysis; safety; leakage current; central dialysis catheter; microbubbles; microemboli; air contamination; transfusion medicine; transfusionsmedicin;

   Sammanfattning : Introduction: Haemodialysis (HD) is a treatment in which blood from the patient is lead through a tubing system into a dialysis device in a extracorporeal circuit. This circuit contains semipermeable membranes (dialyzer). Blood with uraemic toxins flows on one side, and a salt solution flows on the other side. LÄS MER
