1. 16. Organophosphates and phthalates in air and dust from indoor environments : Method development and applied measurements

   Författare :Caroline Bergh; Conny Östman; Peter Haglund; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organophosphate esters; phthalate esters; air; dust; sampling; method development; GC MS; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

   Sammanfattning : Organophosphate and phthalate esters are polymer additives that are frequently found in air and dust in indoor environments. This thesis describes the development and application of air sampling and selective mass spectrometric (MS) determination of these two compound groups. LÄS MER

3. 17. Computations in the Grothendieck Group of Stacks

   Författare :Daniel Bergh; Torsten Ekedahl; David Rydh; Jochen Heinloth; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; matematik;

   Sammanfattning : Given an algebraic group, one may consider the class of its classifying stackin the Grothendieck group of stacks. This is an invariant studied byEkedahl. For certain connected groups, called the special groups bySerre and Grothendieck, the invariant simply gives the inverse of the class ofthe group itself. LÄS MER

4. 18. Destackification and Motivic Classes of Stacks

   Författare :Daniel Bergh; David Rydh; Dan Edidin; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Algebraic geometry; Algebraic stacks; Destackification; Grothendieck ring; Motive; Torus; Classifying stack; Mathematics; matematik;

   Sammanfattning : This thesis consists of three articles treating topics in the theory of algebraic stacks. The first two papers deal with motivic invariants. In the first, we show that the class of the classifying stack BPGLn is the inverse of the class of PGLn in the Grothendieck ring of stacks for n ≤ 3. LÄS MER

5. 19. Social Relations and Health : How do the associations vary across contexts and subgroups of individuals?

   Författare :Daniel Bergh; Curt Hagquist; Bengt Starrin; Viveca Östberg; Karlstads universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social Relations; Social Capital; Health; Health Behaviours; School; Adolescents; Sociologi; Sociology;

   Sammanfattning : Objectives: The aim of this thesis is to study the association between social relations and health in different social spheres, and to examine possible interaction effects. Material and Methods: In Paper I, the link between measures of the psychosocial neighbourhood environment, the psychosocial working environment, and psychosomatic health is analyzed by using a subset of data from the survey Life and Health 2000.

7. 20. The role of microorganisms in prostate cancer development

   Författare :Johanna Bergh Drott; Fredrik Elgh; Torkel Wadström; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostate cancer; aetiology; inflammation; Propionibacterium acnes; patologi; Pathology;

   Sammanfattning : Prostate cancer is the most common cancer among Swedish men, but the aetiology of this disease is largely unknown. There is evidence for a linkage between chronic inflammation and prostate cancer. The mechanisms causing prostate inflammation and how this could promote tumour development and progression are however largely unknown. LÄS MER
