1. 16. The dynamic microfilament system : cellular organization of actin and profilin and their association with cell signalling

   Författare :Lucie Hájková; Karl-Eric Magnusson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Zoological Cell Biology; zoologisk cellbiologi;

   Sammanfattning : Active shape changes and movement of whole cells, and translocations within cells are essential to life. For instance, during embryogenesis cell migration is a central theme. Wound healing depends on increased and directed motile activity of several cell types. LÄS MER

3. 17. Essays on Dynamic Macroeconomics

   Författare :Martin Flodén; Orazio Attanasio; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; nationalekonomi;

   Sammanfattning : This thesis consists of four independent papers in macroeconomics.Labor Supply and Consumption under Uncertainty: Prudence Reconsidered examines how variations in labor supply can be used to self insure against individual specific risks. LÄS MER

4. 18. Alterations in peripheral glucocorticoid metabolism : effects of weight changes

   Författare :Kotryna Simonyté; Cecilia Mattsson; Bo Angelin; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 11ß Hydroxysteroid dehydrogenase 1; obesity; glucocorticoids; cortisol; phosphoenolpyruvate carboxykinase; adipose tissue; liver; Endocrinology; Endokrinologi; medicin; Medicine;

   Sammanfattning : Background: An important role has been suggested for tissue-specific glucocorticoid metabolism in the development of obesity and its complications. 11ß hydroxysteroid dehydrogenase 1 (11ßHSD1) is an enzyme that catalyzes the interconversion of biologically inactive cortisone to active cortisol, thereby regulating its access to glucocorticoid receptors in target tissues.

5. 19. Assessing future effects on lake ecosystem resilience using data analysis and dynamic modelling : Modelling the effects of extreme weather events and climate warming on lakes

   Författare :Jorrit P. Mesman; Bastiaan W Ibelings; Stéphane Goyette; Don C Pierson; Karsten Rinke; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Extreme events; Storms; Modelling; Climate change; Thermal structure; Phytoplankton;

   Sammanfattning : Extreme weather events can have short-term and long-term effects on lake thermal structure, nutrient dynamics, and community composition. Moreover, changes in lake variables induced by global climate change may influence the response and recovery of lake ecosystems to extreme weather events. LÄS MER

7. 20. Metals in Dynamic Chemistry: Selection & Catalysis

   Författare :Brian J.J. Timmer; Olof Ramström; Stéphane Bellemin-Laponnaz; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; constitutional dynamic chemistry; selection; multivalent interactions; carbohydrates; quartz crystal microbalance; catalyst screening; aqueous olefin metathesis; C-H activation; Kemi; Chemistry;

   Sammanfattning : In the adaptation to the oxidative environment on earth, metals played a crucial role for the evolution of life. The presence of metals also allowed access to advanced functions due to their unique coordination sphere and reactivity. LÄS MER
