1. 1. Evolutionary consequences of maternal effects and stress

   Författare :Piotr K. Rowiński; Björn Rogell; Karl Gotthard; Katja Räsänen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; parental effects; meta-analysis; development time; bet-hedging; brain size; evolutionary potential; unpredictable environments; zoologisk ekologi; Animal Ecology;

   Sammanfattning : Maternal effects occur when maternal environment or phenotype influence offspring phenotype, in addition to genetic contribution of the mother. As maternal effects often influence phenotypes that are under natural selection, they hence have evolutionary consequences. LÄS MER

3. 2. Formation of Inclusions and their Development during Secondary Steelmaking

   Författare :Mikael Thunman; Du Sichen; Piotr Scheller; KTH; []

   Sammanfattning : Al–O relations in iron were investigated. Pure iron with varying Al content was equilibrated at 1873 K. The oxygen content of iron with higher Al content than 1.0 mass % was found to be much lower than previous works, while the oxygen content for Al content less than 1 mass% was found to be slightly higher.

4. 3. Experimental Studies of Neutron Deficient Nuclei in the A ≈ 110 and A ≈ 170 Mass Regions

   Författare :Wei Zhang; Bo Cederwall; Piotr Bednarczyk; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics;

   Sammanfattning : This doctoral thesis describes several experimental studies on the structures of neutron-deficient nuclei with mass numbers A≈110 and A≈170. The experiments were carried out at the Accelerator Laboratory of the University of Jyväskylä, Finland, using heavy-ion fusion-evaporation reactions induced by beams of energies around 5 megaelectronvolts/nucleon.
