1. 21. Ligand Dependent Regioselectivity in Palladium Mediated Allylic Alkylation

   Författare :Charlotte Johansson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Palladium; allylic alkylation; η3-allyl palladium complexes; regioselectivity; PN-ligand; memory effects; dynamics; ligand effect; trans effects.;

   Sammanfattning : In this thesis, different aspects on ligand dependent regioselectivity in palladium mediated allylic alkylation have been studied. It is believed that the regioselectivity is a result of nucleophilic attack trans to phosphorous when applying ligands wih different donor atoms. LÄS MER

3. 22. Carbon Dioxide in Supermarket Refrigeration

   Författare :Samer Sawalha; Björn Palm; Eckhard Groll; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2; carbon dioxide; refrigeration system; supermarket; cascade; indirect; trans-critical; modelling; simulation; experiment; safety analysis; comparison; Mechanical energy engineering; Mekanisk energiteknik;

   Sammanfattning : This thesis theoretically and experimentally investigates different aspects of the application of CO2 in supermarket refrigeration. Theoretical analysis has been performed using computer simulation models developed to simulate CO2 indirect, NH3/CO2 cascade, CO2 trans-critical and direct expansion (DX) R404A systems. LÄS MER

4. 23. Medborgarskap efter nationalstaten? : Ett konstruktivt förslag

   Författare :Christian Fernández; Statsvetenskapliga institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Proposal; Constructive analysis; Normative analysis; Residence; Neo-republicanism; European Union; Multiculturalism; Cosmopolitanism; Trans-naitonalism; Citizenship; Post-national citizenship; Political and administrative sciences; Statsvetenskap; förvaltningskunskap;

   Sammanfattning : This thesis is an attempt to formulate a constructive proposal for the ongoing establishment of a post-national European citizenship in the European Union. To the extent that the proposal is post-national, the ambition is to re-conceptualise the idea and ideal of citizenship in a new historical setting. LÄS MER

5. 24. Interleukin 6 trans-signalling : cardiovascular risk marker or therapeutical target?

   Författare :Louise Ziegler; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Interleukin (IL) 6 signals in two pathways. In classical signalling, essential in antimicrobial defence and tissue regeneration, IL6 binds the membrane- bound IL6 receptor (IL6R) which associates with the signal transducing receptor gp130. LÄS MER

7. 25. Peptidyl-prolyl cis-trans Isomerases in the Chloroplast Thylakoid Lumen

   Författare :Anna Edvardsson; Alexander Vener; Bertil Andersson; Per Gardeström; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Peptidyl-prolyl isomerase activity; Cyclophilin; FKBP; Immunophilin; Chloroplast Thylakoid Lumen; protein characterization; Medical cell biology; Medicinsk cellbiologi;

   Sammanfattning : The Sun is the ultimate energy source on Earth. Photosynthetic organisms are able to catalyze the conversion of solar energy to chemical energy by a reaction called photosynthesis. In plants, this process occurs inside a green organelle called the chloroplast. LÄS MER
