1. 16. The Preservation of Favoured Morphs in the Struggle Between Sexes

   Författare :Thomas Gosden; Evolutionär ekologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sexual Selection; Polymorphism; Density-dependence; Population divergence; Zygoptera; Sexual Conflict;

   Sammanfattning : Sexual selection is particularly likely to promote population divergence, because sexual traits are expected to be subject to rapid evolutionary change. Identifying the relative roles of particular barriers to the amount of total reproductive isolation between populations or closely related species can provide important clues to the mechanisms of population divergence and speciation Phenotypic trait differences among populations are thought to reflect the interaction between the intensity of gene flow versus the strength of local selection and drift.

3. 17. My people right or wrong? : a comparative analysis of national sentiments and their meaning

   Författare :Mikael Hjerm; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; national sentiment; national identity; nationalism; attitudes; multiculturalism; nation; xenophobia; comparative research;

   Sammanfattning : In a world of presumed nation-states, nation has been, and still is, an intrinsic part of political legitimization and identity formation. Thus, it is clear that the understanding of nationality and people's relationship too it is of great importance for our understanding of how a stable society, partly built on nationality, can prevail in a world of migration consisting of individuals with diverging moral, religious and cultural conceptions.

4. 18. Advances in droplet evaporation

   Författare :Giandomenico Lupo; Christophe Duwig; Sébastien Tanguy; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : Droplet evaporation (and condensation) is one of the most common instances of multiphase flow with phase change, encountered in nature as well as in technical applications. Examples include falling rain drops, fogs and mists, aerosol applications like electronic cigarettes and inhalation drug delivery, and engineering applications like spray combustion, spray wet scrubbing or gas absorption, spray drying, flame spray pyrolysis.

5. 19. Nitric oxide and evaluation of different treatments in experimental colitis and inflammatory bowel disease

   Författare :Sofie Lundberg; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), is a chronic inflammatory disorder of unknown etiology of the gastrointestinal tract. Central features of IBD are increased nitric oxide (NO) generation in the gut lumen and dysfunction in regulation of leukocyte recruitment from the blood stream towards the affected tissue. LÄS MER

7. 20. Analysis of Transvascular Transport Phenomena in the glomerular and peritoneal microcirculation

   Författare :CARL ÖBERG; Njurmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Peritoneal dialysis; glomerular filtration barrier; pore model; automated peritoneal dialysis APD ; three-pore model;

   Sammanfattning : The current work is devoted entirely to the study of passive transport phenomena, or more specifically, the more simple diffusion, electric migration and filtration of solute matter and water over glomerular and peritoneal capillary walls. The driving forces behind such trans-capillary transport phenomena have long been assumed to be simple gradients of concentration, hydrostatic pressure and electric potential. LÄS MER
