1. 6. Modeling the Microstructural Evolution during Hot Deformation of Microalloyed Steels

   Författare :Linda Bäcke; Stefan Jonsson; Eric J. Palmiere; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modeling; austenite; microalloyed steels; hot deformation; microstructure evolution; static recrystallization; dynamic recrystallization; metadynamic recrystallization<; Materials science; Teknisk materialvetenskap;

   Sammanfattning :   This thesis contains the development of a physically-based model describing the microstructural evolution during hot deformation of microalloyed steels. The work is mainly focused on the recrystallization kinetics. During hot rolling, the repeated deformation and recrystallization provides progressively refined recrystallized grains. LÄS MER

3. 7. Impact of climate variability on dynamic groundwater storage in mid- to high latitude countries

   Författare :Michelle Nygren; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; climate change; time series analysis; groundwater statistics; Sweden; drought; cold region hydrogeology; groundwater memory;

   Sammanfattning : Climate change will alter the hydrological cycle, potentially changing dynamic groundwater storage and increasing groundwater drought risk. Climate influences groundwater storage directly via changes in groundwater recharge, but groundwater drought responsiveness further depends on groundwater system characteristics. LÄS MER

4. 8. Controlling DNA compaction and the interaction with model biomembranes

   Författare :Marie-Louise Ainalem; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; model biomembrane; DNA compaction; cryo-TEM; null ellipsometry; dynamic light scattering; toroid; bilayer; neutron reflectivity; dendrimer; PAMAM; DNA; poly amido amine ;

   Sammanfattning : The studies described in this thesis forms part of a larger collaborative project, Neonuclei, with the objective to design a module for packaging the negatively charged DNA into a ”neonucleus” with transcription competence. There are many applications that require control of DNA compaction, i.e. packaging or condensation. LÄS MER

5. 9. One coin - One vote : the rural political power shift that pushed Sweden towards industrialization

   Författare :Erik Lindgren; Björn Tyrefors; Per Pettersson-Lidbom; Erik Grönqvist; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Development; Education; Infrastructure Investment; Railroads; Historical data; Political Institutions; Infant mortality and Weather; Growth; Economics; nationalekonomi;

   Sammanfattning : The Causal Effect of Political Power on the Provision of Public Education: Evidence from a Weighted Voting SystemWe estimate how political power affects the provision of public education in local governments, using data from a nondemocratic society where voters received votes in proportion to their taxable income. This was the system used in Swedish local governments during the period 1862–1909. LÄS MER

7. 10. Forest-savanna transitions: Understanding adaptation and resilience of the tropical forest ecosystems using remote sensing

   Författare :Chandrakant Singh; Ingo Fetzer; Lan Wang-Erlandsson; Ruud van der Ent; Stefano Manzoni; Udita Sanga; Vivian Ribeiro; Stockholms universitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Environmental Sciences; miljövetenskap; Ecology and Evolution; ekologi och evolution; Hydrology; hydrologi;

   Sammanfattning : Climate and deforestation-induced changes in precipitation drive tropical forest-savanna transitions. However, precipitation alone provides a superficial understanding of the underlying mechanism behind these transitions. This is because our knowledge of how vegetation responds to changes in hydroclimate is fragmented. LÄS MER
