   Författare :Wei Xiao; Yves Zenou; Peter Rupert; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Search; Unemployment; Cities; Crimes; Rural-urban migration; Economics; nationalekonomi;

   Sammanfattning : Search Frictions, Unemployment, and Housing in Cities: Theory and PoliciesWe propose an urban search-matching model with land development. We characterize the steady-state equilibrium and then discuss the issue of efficiency. LÄS MER

3. 2. Role of adhesion molecules and chemokines in TNF-alpha-induced leukocyte recruitment

   Författare :Xiao Wei Zhang; Kirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; intravital microscopy; microcirculation; inflammation; adhesion; leukocyte; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

   Sammanfattning : Migration of leukocytes from the circulating blood into the extravascular tissue is a key component in inflammatory reactions. Leukocyte extravasation (rolling-activation-adhesion-transmigration) is strictly coordinated by adhesion molecules and chemokines expressed on cell surfaces and in tissues. LÄS MER

4. 3. Toward Energy-efficient Physical Vapor Deposition : Routes for Replacing Substrate Heating during Magnetron Sputtering by Employing Metal Ion Irradiation

   Författare :Xiao Li; Grzegorz Greczynski; Ivan Petrov; Lars Hultman; Jyh-Wei Lee; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PVD; Magnetron sputtering; Thin films; HiPIMS; TiAlN; Energy efficiency;

   Sammanfattning : In this Thesis, magnetron sputtering is perfected as an environmental-friendly deposition technique. I performed systematic studies of a novel approach - hybrid high-power impulse and dc magnetron co-sputtering (HiPIMS/DCMS) with metal-ion-synchronized substrate bias pulses. LÄS MER
