1. 1. Effects of cigarettes, e-cigarettes and Swedish snus on vascular function

   Författare :Lukasz Antoniewicz; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Cigarette smoking is considered one of the leading causes of preventable morbidity and premature death worldwide. A large portion of this is attributable to cardiovascular disease such as ischemic heart disease and stroke. LÄS MER

3. 2. Single-Electron Tunneling Spectroscopy in Magnetic Nanoparticles and Molecular Magnets

   Författare :Lukasz Michalak; Fasta tillståndets fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; master equation; magnetic nanoparticles; spin accumulation; molecular magnets; TMR; tunneling magnetoresistance; F-SET; ferromagnetic single-electron transistor; single-electron tunneling; nanomagnetism; spintronics; Coulomb blockade;

   Sammanfattning : This thesis deals with single-electron tunneling in transistor-like devices in which the central electrode is either a metal nanoparticle (possibly ferromagnetic) or a molecular magnet. The investigated systems split into two different categories, depending on the size of the central island. LÄS MER

4. 3. Swedish refugee policymaking in transition? : Czechoslovaks and Polish Jews in Sweden, 1968-1972

   Författare :Łukasz Górniok; Martin Hårdstedt; Malin Thor Tureby; Umeå universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Sweden; Czechoslovak refugees; Polish-Jewish refugees; Cold War; 1968-1972; active foreign policy; refugee policy; multiculturalism; national security; labour market considerations;

   Sammanfattning : The aim of this dissertation is to examine the Swedish government’s responses to the Prague Spring, the Warsaw Pact invasion of Czechoslovakia, the anti-Semitic campaigns in Poland and, first and foremost, to Czechoslovak and Polish-Jewish refugees fleeing their native countries as a result of these event during the formative period of the late 1960s and early 1970s. This has been accomplished by examining the entire process from the decision to admit the refugees in 1968, to their reception and economic integration into Swedish society during the seven-year period necessary for acquiring Swedish citizenship.

7. 5. Nonlinear Propagation of Partially Incoherent Light

   Författare :Lukasz Helczynski-Wolf; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis deals with consequences of partial incoherence on light propagation in nonlinear media. A new approach, based on the Wigner transform method, has beed developed and used to investigate several important problems in nonlinear light propagation. LÄS MER
