3. 12. En hiar atti rikR : Om elit, struktur och ekonomi kring Uppsala och Mälaren under yngre järnålder

   Författare :John Ljungkvist; Stefan Brink; Kent Andersson; Dagfinn Skre; Uppsala universitet; []
   Nyckelord :Archaeology; Late Iron Age; Viking Age; Vendel Period; economy; landscape; elite; graves; settlements; central places; Arkeologi; arkeologi; Archaeology;

   Sammanfattning : In the Late Iron Age, the Mälaren region contained a clearly stratified society and many sites in the landscape indicate the presence of an upper stratum, an elite. This concept – elite – may perhaps be seen as problematic, but in this case it is decidedly more neutral, and considerably less limiting and excluding than many other concepts. LÄS MER

4. 13. Combinatorial Protein Engineering Of Affibody Molecules Using E. Coli Display And Rational Design Of Affibody-Based Tracers For Medical Imaging

   Författare :Ken G. Andersson; John Löfblom; Stefan Ståhl; Harald Kolmar; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; directed evolution; microbial display; E. coli; Affibody molecule; autotransporter; medical imaging; HER receptor family; Sortase A; Bioteknologi; Biotechnology;

   Sammanfattning : Directed evolution is today an established strategy for generation of new affinity proteins. This thesis describes the development of a cell-display method using Escherichia coli for directed evolution of Affibody molecules. LÄS MER

5. 14. Molecular gas in the galaxy M83 : Its distribution, kinematics, and relation to star formation

   Författare :Andreas Andersson Lundgren; Hans Olofsson; John Whiteoak; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular gas; Galaxies; Galaxies individual: M83; Star formation; Galactic dynamics; Astronomy and astrophysics; Astronomi och astrofysik;

   Sammanfattning : The barred spiral galaxy M83 (NGC5236) has been observed in the 12CO J=1–0 and J=2–1 millimetre lines with the Swedish-ESO Submillimetre Telescope (SEST). The sizes of the CO maps are 100×100, and they cover the entire optical disk. The CO emission is strongly peaked toward the nucleus. LÄS MER

7. 15. Union-Fertility Nexus and Fertility Variation in Sub-Saharan Africa : The Role of Marital Dissolution and Repartnering

   Författare :Ben Malinga John; Elizabeth Thomson; Gunnar Andersson; Natalie Nitsche; Myrskyla Mikko; Monica Grant; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; fertility; fertility transition; marriage; marriage formation; marital dissolution; repartnering; Sub-Saharan Africa; demographic methods; sociologisk demografi; Sociological Demography;

   Sammanfattning : The role of marital dissolution and repartnering in shaping fertility patterns in sub-Saharan Africa (SSA) has been largely overlooked, even though marital dissolution and repartnering are fundamental features of marriage dynamics in this region. This dissertation addresses this gap by using existing statistical and demographic techniques and developing new demographic methods to (i) examine the relationship between union dissolution and fertility at the micro level (Study I); (ii) assess the dynamics of union dissolution, including the levels of all-cause first union dissolution, the timing of first union dissolution, and the reproductive years spent outside of marriage due to union dissolution (Studies II & III); and (iii) analyze the influence of marital dissolution and repartnering on macro fertility patterns in SSA (Study IV).
