2. 11. Holocene climate and atmospheric circulation changes in northern Fennoscandia : Interpretations from lacustrine oxygen isotope records

   Author : Christina E. Jonsson; Gunhild Rosqvist; Jan Seibert; Philip Barker; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; oxygen isotope; diatom silica; lake sediment; atmospheric circulation; North Atlantic Oscillation; northern Fennoscandia; The Holocene; Little Ice Age; Physical geography; Naturgeografi; Physical Geography; naturgeografi;

   Abstract : This thesis investigates how variations in the oxygen isotopic composition of lake waters in northern Fennoscandia are recorded in lake sediment archives, especially diatoms, and how these variations can be used to infer past changes in climate and atmospheric circulation. Results from analyses of the oxygen isotopic composition of lake water samples (δ18Olakew) collected between 2001 and 2006 show that δ18O of northern Fennoscandian lakes is mainly controlled by the isotopic composition of the precipitation (δ18Op).

4. 12. Analysing Fault Tolerance for Erlang Applications

   Author : Jan Henry Nyström; Bengt Jonsson; Sven-Olof Nyström; John Hughes; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; formal methods; symbolic evaluation; fault tolerance; erlang; Computer engineering; Datorteknik; Computer Systems; Datorteknik;

   Abstract : ERLANG is a concurrent functional language, well suited for distributed, highly concurrent and fault-tolerant software. An important part of Erlang is its support for failure recovery. Fault tolerance is provided by organising the processes of an ERLANG application into tree structures. READ MORE

5. 13. Modified Glycopeptides Targeting Rheumatoid Arthritis : Exploring molecular interactions in class II MHC/glycopeptide/T-cell receptor complexes

   Author : Ida E. Andersson; Jan Kihlberg; Anna Linusson Jonsson; Craig Crews; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Major histocompatibility complex; class II MHC; T-cell receptor; rheumatoid arthritis; collagen-induced arthritis; glycopeptide; amide bond isostere; comparative modeling; rational design; molecular docking; molecular dynamics simulation; statistical molecular design; Bioorganic chemistry; Bioorganisk kemi; organisk kemi; Organic Chemistry; Biorganic Chemistry; bioorganisk kemi; datorlingvistik; computational linguistics;

   Abstract : Rheumatoid arthritis (RA) is an autoimmune inflammatory disease that leads to degradation of cartilage and bone mainly in peripheral joints. In collagen-induced arthritis (CIA), a mouse model for RA, activation of autoimmune CD4+ T cells depends on a molecular recognition system where T-cell receptors (TCRs) recognize a complex between the class II MHC Aq protein and CII259-273, a glycopeptide epitope from type II collagen (CII).

6. 14. Redefining the essential molecular aspects that drive interactions between small molecules and G-quadruplex DNA

   Author : Måns Andréasson; Erik Chorell; Anna Linusson Jonsson; Jan Kihlberg; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; G-Quadruplexes; DNA; Oncogenes; G4 ligands; heterocycles; macrocycles; organic synthesis; molecular interactions; rational compound design; medicinal chemistry.; medicinal chemistry; läkemedelskemi; organisk kemi; Organic Chemistry;

   Abstract : G-Quadruplex (G4) structures are secondary nucleic acid structures located in guanine-rich regions of DNA and RNA sequences, involved in gene regulation and cellular maintenance. Efforts to target G4s in a therapeutic setting are scarce, mainly due to vague details about the binding interactions between the ligands and the G4 structure combined with the lack of emphasis on drug-like properties early in the ligand development process.

7. 15. Happy hour? Studies on well-being and time spent on paid and unpaid work

   Author : Katarina Boye; Jan O. Jonsson; Marie Evertsson; Sonja Drobnič; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Well-being; paid work; housework; gender equality; family policy; parental leave; social comparison; Sweden; Europe; Sociology; Sociologi; Sociology; sociologi;

   Abstract : The present thesis focuses on causes and consequences of paid working hours and housework hours among women and men in Sweden and Europe. It consists of four studies. Study I investigates changes in the division of housework in Swedish couples when they become parents. READ MORE
