2. 1. Developments and application of neutron noise diagnostics of sodium cooled fast reactors

   Author : Florian Zylbersztejn; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neutron monitoring; Neutron noise; Fast neutron reactors; Core volume fluctuations;

   Abstract : The Sodium cooled Fast Reactor (SFR) is one of the six reactor types selected by the Generation-IV international forum (GIF), and the building of an industrial prototype is planned in France. The safety standard of the future SFR has to be equivalent to the EPR's. READ MORE

4. 2. The Littorina transgression in southeastern Sweden and its relation to mid-Holocene climate variability

   Author : Shiyong Yu; Kvartärgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; marklära; kartografi; Fysisk geografi; geomorfologi; climatology; cartography; pedology; geomorphology; Physical geography; tidal action; solar forcing; global meltwater pulse; North Atlantic storminess; climate changes; shoreline displacements; sea-level fluctuations; Littorina transgression; Baltic Sea; klimatologi;

   Abstract : Lateglacial and Holocene shoreline displacement along the Baltic coast resulted from both the isostatic land uplift and the ice-volume-equivalent sea-level rise. Relative changes of these two components led to alternating contact/isolation of the Baltic Basin with the North Sea during the Holocene. READ MORE

5. 3. Influence of green pellet properties on pelletizing of magnetite iron ore

   Author : Seija Forsmo; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

   Abstract : Magnetite iron ore green pellets are produced by balling moist concentrates to green pellets, which are then dried, oxidized to hematite, sintered, cooled and transported to steelmaking plants. The existing theory for balling is based on the capillary theory, but its applicability under industrial balling conditions is unclear. READ MORE

6. 4. Osmoregulation at different stages of the yeast life cycle

   Author : Cecilia Geijer; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; stress signalling; osmoregulation; aquaporins; cerevisiae; germination; germination;

   Abstract : The ability to adapt to changing and potentially harmful conditions in the surrounding environment is crucial for fitness and survival of all living cells; in particular unicellular organisms, since they are frequently exposed to stress factors such as heat, drought, nutritional starvation and toxic substances. The aim of this thesis is to determine how cells respond to osmotic and nutritional changes in the environment and how downstream targets of signalling cascades are regulated. READ MORE

7. 5. Multi-level Interactions between Fisheries and Trade : Modeling intertwined social-ecological systems

   Author : Laura G. Elsler; Schlüter Maja; Florian Diekert; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; multi-level interactions; social-ecological model; trade relationships; complexity; inequality in fisheries; fisheries sustainability; seafood trade; international markets; fisheries collapse; Sustainability Science; vetenskap om hållbar utveckling;

   Abstract : Sustainable and equitable fisheries are central for addressing the challenges of the UN Sustainable Development Goal 14: Life Below Water. International trade, once presented by Walrasian economists as a panacea for fisheries development, has not markedly decreased poverty and has been related to the overexploitation of marine species.
